Abstract

The utility model discloses an attaching device for aluminum electrolysis. The utility model is composed of a cylinder, an upper drawing rod, a sealing valve cover, a constant volume cylinder and a bell jar valve. The upward and downward move of the inner piston of the cylinder drives the sealing valve cover and the bell jar valve positioned on the upper drawing rod to move upwards and downwards simultaneously. The sealing valve cover is a lower cone body, the bell jar valve is an upper cone body and the periphery of the sealing valve cover is a material box. The piston of the cylinder is upward lifted and the sealing valve cover is in open state to obtain the material filling step. The raw material enters the constant volume cylinder from the material box. When the piston of the cylinder downward moves, the upper drawing rod also downward moves, the sealing valve cover is closed and the bell jar valve cover opens to obtain the material feeding step. The constant volume material filling and feeding operation of the aluminum electrolysis can be finished by the cylinder work to carry out automatic production. The utility model has the advantages of simple structure, convenient installation and use, flexible control, high sensibility and stable work. The utility model can be in connecting use with the automatic controlling device without manual control. The utility model reduces the personal disoperation caused by environmental pollution.

Description

The brushless constant-volume blanking device of used for aluminium electrolysis

Technical field

The utility model relates to a kind of electrolysis of aluminum accessory device, is adapted at installing and using on the aluminium cell.

Background technology

At present, because the continuous development and the raising of Aluminium Electrolysis, the constant-volume blanking device development is also brought in constant renewal in and is regenerated along with the aluminum electrolyzation technology development, be that what to use on blanking device is board plug type the earliest, owing to this structure at high temperature is out of shape and is broken down, developed into the pneumatic type blanking device afterwards, because the constant volume precision is low, can't satisfy intelligent requirement, it is the main flow that develops at present that brush blanking device is arranged, it has the precision height, it is reliable relatively to work, and becomes aluminium manufacturer's preferred unit in for some time, but its weak point is card brush phenomenon often to occur, the easy chargings of epicoele etc. make troubles for automatic production in enormous quantities.

Summary of the invention

For solving the deficiency of above constant-volume blanking device structure, the purpose of this utility model provides a kind of electrolysis of aluminum brushless constant-volume blanking device, utilizes the structure of brushless air pressure, with reach control flexibly, constant volume precision height, purpose easy to install.

Structure design of the present utility model is to realize like this, this brushless constant-volume blanking device is by cylinder, upper connecting rod, sealed valve cap, constant volume tube and belljar valve are formed, whole device is vertical stratification, detailed structure is the top cylinder that is, be provided with air inlet/outlet in the side, have the boiling air inlet port simultaneously, vertical fixing has upper connecting rod below the cylinder, and the upper connecting rod center fixed has sealed valve cap, sealed valve cap is tapered downwards, lower end is fixed with belljar valve, and belljar valve upwards is vertebra shape, in the sealed valve cap both sides boiling dish is housed, connect with the boiling air inlet port, the assurance blanking is even, is the constant volume tube below the boiling dish, adopts Bolt Connection between constant volume tube and cylinder, around the sealed valve cap is hopper, connect with ring flange below the cylinder by upper bolt, sealing rubber cover is equipped with in the centre, and whole device is become an integral body (as shown in Figure 1) after installing.

The utility model has following advantage compared with the prior art: simple in structure, easy to install; Maximum characteristics: control flexible, highly sensitive, working stability, can connect use with automatic control device,, reduced the infringement of environmental pollution to the person without hand control.

Description of drawings

Fig. 1 is the brushless constant-volume blanking device structure principle chart of aluminium cell.

Among the figure: 1 cylinder, 2 upper connecting rods, 3 sealed valve caps, 4 belljar valves, air inlet/outlet on 5 cylinders, air inlet/outlet under 6 cylinders, 7 boiling air inlet ports, 8 ring flanges, 9 sealing rubber cover, 10 hoppers, 11 constant volume tubes, 12 boiling dishes

Embodiment

Its structure as shown in drawings, cylinder 1 is equipped with on the blanking device top, lateral all have air inlet/outlet 5 up and down, 6, the gas inlet hole at present of working, carry on the piston, upper connecting rod makes progress, the upper surface hole air inlet, then cylinder piston is downward, upper connecting rod is downward, is fixed with sealed valve cap 3 on the upper connecting rod, is following vertebra shape, the lower end is belljar valve 4 fixedly, be last vertebra shape, belljar valve 4 outsides are the constant volume tube, adopt Bolt Connection between constant volume tube and the cylinder, around the upper connecting rod is hopper 10, because action of gravity, raw material flow to naturally sealed valve cap around, cylinder operation during work, upper connecting rod 2 pull-ups, wherein sealed valve cap is opened with funnel on every side, for filling the material stage, after the constant volume tube is full of, the cylinder upper connecting rod is transferred as required, then sealed valve cap is closed, and belljar valve 4 is opened, and is the Aluminium Electrolysis material loading stage, so just can finish the constant volume loading and unloading function of Aluminium Electrolysis automatically, produce and carry out automatically.
