Abstract

DC60 (12/07/55) This invention provides a machine and a means for the suction and exhaust of the storage tanks for Sand in a casting machine with a less valve opening and preventing sand from sticking to the inside of the valve for Ventilation while air is ventilated Machine for suction and exhaust ventilation from the storage tank for The sand in the casting machine consists of a storage tank for sand in the casting machine. Porous hulls that are arranged in storage tanks For sand and that is far from the inner skin of the storage tank for sand The empty chamber formed by the surface. The exterior of the hull is porous and the inner surface of the sand storage tank. The seal is placed on the edge of the tip. The end of the tank nozzles for sand filling and to expand when compressed air is supplied inside the seal, pilot operating valves for both suction and ventilation, which are seamlessly connected to the empty chamber. And an open-close valve that is flowable connected to the pilot operating valve for both suction and ventilation and to Inside leak-proof The invention provides a machine and a method for the suction and exhaust of the storage tanks for Sand in a casting machine with a less valve opening and preventing sand from sticking to the inside of the valve for Ventilation while air is ventilated Machine for suction and exhaust ventilation from the storage tank for The sand in the casting machine consists of a storage tank for sand in the casting machine.

Apparatus for suction and ventilation from the storage tank for sand in the casting machine. which Includes: Storage tank for sand in the casting machine The porous hulls are supplied quickly in the sand storage tanks and beyond the inner surface of the sand storage tank, the vacant chamber formed by the perforated body outer surface and the inner surface of the sand storage tank. A seal is placed at the edge of the tip of the nozzle for the sand filling of the sand tank. And to expand when compressed air is supplied from the inside The pilot operating valve for both suction and ventilation is flowable to the chamber, and the valve that is flowable to the pilot operating valve for both suction and discharge. Air and connect to the inside, leak proof Where the speed control valve is provided between the on-off valve and the pilot operating valve for both Suction and ventilation and between the valve and the inside of the seal -------------------------------------------------- -------------------------------------------------- 1. a machine for suction and ventilation from the collecting tank for sand in the casting machine, which Includes: Storage tank for sand in the casting machine The porous hulls arranged in the sand storage tank and beyond the inner surface of the sand storage tank, the vacant chamber formed by the perforated body outer surface and the inner surface of the sand storage tank. That was placed at the edge of the tip of the nozzle for the sand filling of the storage tank for sand And to expand when compressed air is supplied from inside the leak side The pilot operating valve for both suction and ventilation is flowable to the chamber, and the valve that is connected to the flow through the pilot operating valve for both suction and discharge. Air and connect to the inside, leak proof 2. Apparatus for suction and exhalation from the sand hopper in the casting device of claim 1 where the speed control valve is positioned between the on-off valve and the pilot operating valve for Both suction and ventilation, and between the valve and the inside of the leak barrier. 3.Method for suction and ventilation from the collector for sand in the casting machine, which is used Machine for suction and ventilating of the storage tank for sand in the one-method holder of the right holder, which consists of the procedure of: filling the foundry sand collected in the sand tank into the bottle by opening the valve. On-off While casting sand is stored in a storage tank for sand While the leak barrier is expanded to allow the splice to be firmly attached. To the edge of the end of the slot for introducing sand into the bottle To make the valve conductive for Suction and ventilation are opened to allow compressed air to be supplied inside the storage tank for sand through the void and perforated hull, and to allow compressed air to be vented from the sand tank through the perforated hull and void by closing. On-off valve to allow the seal to shrink so that it is disengaged from the edge of the far end of the channel for conduction. Sand enters the bottle and so that the suction and ventilation operating valves are closed. 4. Method for suction and discharge from the hopper for sand in the right holder 3, where the speed control valve is placed between the on-off valve and the pilot operating valve for Both suction and ventilation and between the valve and the seal inside. And where the control valve The velocity is adjusted to allow the seal to expand so that it is securely attached to the edge of the tip of the The opening for introducing sand into the bottle before the suction and ventilation pilot operating valve is opened.
