Abstract
The utility model relates to an air permeable piston type constant volume crust breaking material feeding device for aluminium electrolysis. The utility model has the structure that one end of a connection rod in a shell body is connected with a cylinder, and the other end of the connection rod is connected with a movable sealing head; the middle part of the connection rod is connected with the air permeable piston, and a material inlet is arranged on the shell body; a striking head is arranged on the movable sealing head, the cylinder is connected with an electromagnetic valve, and a contact face on the movable sealing head is contacted with an end face of the shell body; a constant volume chamber is formed between the end face of the air permeable piston and the movable sealing head in the shell body. In the utility model, disposable investment of an electrolytic tank is reduced, the acquisition cost, the maintenance frequency, and the maintenance cost of the device are respectively reduced; the gas consumption quantity is reduced by 50 percent, and the operational reliability of the device is enhanced.
Description
The utility model relates to a kind of aluminum electrolyzation technology equipment, particularly a kind of used for aluminium electrolysis air-permeable piston formula constant volume crust breaking blanking device.
In the prior art, in the production process of carrying out electrolytic aluminum, the electrolytic aluminum that needs to be frozen into shell breaks up the quantitative aluminum oxide powder of back adding, to guarantee normal production; For accomplishing this point, present technology is that taper, blanking device are designed respectively, use, and the problem that causes like this is: the acquisition cost of equipment is than probability height higher, maintenance, and maintenance cost is many, the poor reliability of equipment.
The purpose of this utility model is: taper, blanking device are designed to one and use, reduce acquisition cost, reduction frequency of maintenance and the maintenance cost of equipment like this, improve the working reliability of equipment.
The utility model is to constitute like this: an end of the connecting rod (3) in housing (9) connects cylinder (2), the other end of connecting rod (3) is connected with movable end socket (7), the middle part of connecting rod (3) also is connected with air-permeable piston (4), offer feed port (6) on the housing (9), attacking head (8) is installed on the movable end socket (7), cylinder (2) is connected with magnetic valve (1), there is a contact surface (10) to contact on the movable end socket (7), in housing (9) with the end face (11) of housing (9), form a constant volume chamber (12) between the end face of air-permeable piston (4) and the movable end socket (7).
The utility model has compared with prior art reduced the one-time investment of electrolyzer, has reduced acquisition cost and the frequency of maintenance and the maintenance cost of equipment, and it is about 50% to reduce gas consumption, has improved the working reliability of equipment.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: an end of the metal connecting rod (3) in metal shell (9) connects cylinder (2), the other end of connecting rod (3) is connected with movable end socket (7), the middle part of connecting rod (3) also is connected with air-permeable piston (4), offer feed port (6) on the housing (9), metal attacking head (8) is installed on the movable end socket (7), cylinder (2) is connected with magnetic valve (1), there is a contact surface (10) to contact on the movable end socket (7), in housing (9) with the end face (11) of housing (9), form a constant volume chamber (12) between the end face of air-permeable piston (4) and the movable end socket (7).
During use, magnetic valve (1) work makes cylinder drivening rod (3) move, when air-permeable piston (4) moves to the left side of feed port (6), be contained in aluminum oxide powder in the hopper (5) from the end of feed port (9) and (11) closely contact, aluminum oxide powder can not spill; Under the work of magnetic valve, when air-permeable piston (4) moves to the right side of feed port (6), the contact surface (10) of movable end socket (7) breaks away from the end face (11) of housing (9), attacking head (8) motion, the electrolytic aluminum that to form shell punctures, at this moment, because air-permeable piston (4) seals feed port (6), make the aluminum oxide powder that is contained in the hopper (5) can not enter again in the constant volume chamber (12) from feed port (6), can break away from along with the end face (11) of the contact surface (10) of movable end socket (7) and housing (9) and from the constant volume chamber, spill according to the quantity that pre-sets and entered the indoor aluminum oxide powder of constant volume, enter in the electrolyzer, guarantee that the production of electrolytic aluminum is normally carried out; Said process is finished the operation of crust breaking, blanking so repeatedly.
