AN IMPROVED EQUIPMENT FOR IMPREGNATING FERROUS & NON-FERROUS CASTINGS, i.e. VERTICAL TRANSVERSE SYSTEM
3. Preamble to the Description:
Field of Invention
The present invention relates to improved equipment for impregnating ferrous & non-ferrous castings, i.e. vertical transverse system.
Background of the Invention & the Related Art
In the present system for impregnating ferrous & non-ferrous castings, two tanks viz. reservoir & autoclave are used. Herein, the workload (components to be impregnated) is loaded into the basket imbedded in the autoclave. The sealant in put in an adjacent tank i.e. in the reservoir. Further, the high-speed vacuum is drawn on basket containing the workload in the autoclave to clean the porosity of the workload. At the same time, similar high-speed vacuum is subjected to the reservoir also. Further, the valve between the reservoir and the autoclave is opened allowing the transfer of the sealant from the reservoir into the autoclave. With the transfer of the sealant into the autoclave the basket containing workload is immersed in the sealant. Then, with the help of the high speed vacuum still present in the autoclave and being maintained until the workload in basket is thoroughly impregnated or forcing the sealant into the porosity sealing. Then, the unused sealant returns to the original tank i.e. the reservoir. Further, the high-speed vacuum in the autoclave is released and the lid of the autoclave is opened to enable the charge basket containing the workload to be removed from the autoclave.
However, a need was felt to invent a system, which shall be better than the current system, which shall be more space effective.
Also, the manufacturing cost of the same is quite high because of the use of two tanks.

Similarly, as the tank height is more, more volume of air to be sucked (i.e. part of the dry cycle), hence resulting in non-effective porosity sealing.
4. Description of the invention:
In the invention under consideration, only one tank is used in the impregnation process. Within the said tank, hydraulic/pneumatic cylinder filled with the sealant/liquid/air upto an appropriate level is used for holding (hooked on) the basket in which the workload is placed. The basket is so held on the hydraulic/pneumatic cylinder that, it allows upward & downward movement of the basket with the help of piston. This up & down movement of the basket allows the impregnation process to commence. There is a pneumatic cylinder attached to the tank to allow the locking & unlocking of the basket and further allowing the charge basket containing the workload to move upwards or downwards.
Herein, in the tank containing the charge basket containing the workload, a highspeed vacuum is created to clean the porosity of the workload. Further, there is a pneumatic cylinder placed on the tank for locking and unlocking of the basket. By unlocking of the basket with help of the pneumatic cylinder, the basket is allowed to move downwards with the help of the piston towards the lower part of the tank where sealant is present. With the movement of the piston, the sealant/liquid/air in the hydraulic/pneumatic cylinder is slowly pushed down making the basket to move downwards at an appropriate speed. With this the basket containing the workload is properly immersed in the sealant. Once, the basket containing the workload has sufficiently moved down and the same has appropriately immersed in the sealant, with the help of the high speed vacuum maintained in the tank the sealant is forced into the porosity sealing. Further, the vacuum in the tank is released and the lid of the tank is opened and the charge basket is pushed upwards in the tank to enable the charge basket to be removed from the tank.

Description of the Invention with the Drawings:
In the invention under consideration, there is only one tank (1) used for the impregnation process. Within the said tank (1) a hydraulic/pneumatic cylinder (2) which is filled with the sealant/liquid/air within the Hydraulic/Pneumatic Cylinder (3) upto an appropriate level. The hydraulic/pneumatic cylinder (2) for holding (hooked on) the charge basket (4) in which the workload to be impregnated (5) is placed. The charge basket (4) is held in a particular fashion on the hydraulic/pneumatic cylinder (2). This holding of the charge basket (4) in a particular fashion allows upward &/or downward movement of the said charge basket (4) with the help of piston (7) fitted inside the hydraulic/pneumatic cylinder (2). This smoother up/down movement of the charge basket (4) is facilitated by the existence of the sealant/liquid/air within the Hydraulic/Pneumatic Cylinder. With this up &/or down movement of the charge basket (4) allows the impregnation process to happen.

There is a pneumatic cylinder (6) attached tank (1) at the top left corner of the said tank (1). The pneumatic cylinder is meant for the locking &/or unlocking of the charge basket (4). With this locking &/or unlocking of the charge basket (4), the said charge basket (4) moves slowly downwards with the help of the piston (7) fitted inside the hydraulic/pneumatic cylinder (2). On completion of this downward movement of the charge basket (4), the process of impregnation commences.
To commence with the actual process of impregnation, within the tank (1), the charge basket (4) further containing the workload to be impregnated (5), a highspeed vacuum is created. With creation of this high-speed vacuum the porosity of the workload to be impregnated (5) is cleaned to enable a proper impregnation on the workload to be impregnated (5). On the lapse of the required time for cleaning the porosity of the workload to be impregnated (5), pneumatic cylinder placed at the top left corner of the tank (1), unlocks of the charge basket (4) and allows the said charge basket (4) to move downward slowly with the help of the piston (7) which is placed inside the hydraulic cylinder (2). With this downward movement of the charge basket (4) the workload to be impregnated (5) placed in the charge basket (4) slowly starts immersing in the sealant in the bottom portion of the tank (8) present in the tank (1).
Once, the charge basket (4) containing the workload (5) has sufficiently moved down towards the bottom end of the tank (1) and the workload to be impregnated (5) has immersed properly in the sealant in the bottom portion of the tank (8), with the help of the high-speed vacuum maintained in the tank (1) the sealant in the bottom portion of the tank (8) is forced into the porosity sealing.
When the sufficient time for porosity sealing is lapsed as per the time set for the process of impregnation, the high-speed vacuum in the tank (1) is released and the lid of the tank (9) is opened and the charge basket (4) is pushed upwards in the tank (1) to enable the charge basket (4) to be removed from the tank (1).

ABSTRACT
In the invention under consideration relating to an improved equipment for impregnating ferrous & non-ferrous castings, i.e. vertical transverse system, only one tank is used in the impregnation process. Within the said tank, hydraulic/pneumatic cylinder filled with the sealant/liquid/air upto an appropriate level is used for holding (hooked on) the charge basket in which the workload is placed. The basket is so held on the hydraulic/pneumatic cylinder that, it allows upward & downward movement of the charge basket with the help of piston and the sealant/liquid/air /air in the hydraulic/pneumatic cylinder. A high-speed vacuum is created within the tank to clean the porosity of the workload to be impregnated. Further, there is a pneumatic cylinder attached to the tank to allowing the locking & unlocking of the basket and further allowing the charge basket containing the workload to move upwards or downwards. By unlocking of the charge basket with help of the pneumatic cylinder, the basket moves downwards towards the lower part of the tank where sealant is present and finally basket containing the workload is immersed in the sealant. Once, the basket containing the workload has sufficiently and properly immersed in the sealant, with the help of the high-speed vacuum maintained in the tank the sealant is forced into the porosity sealing. Further, the vacuum in the tank is released and the lid of the tank is opened and then charge basked is pushed upwards in the tank to enable the same to be removed from the tank.
