Abstract

The utility model relates to a directly operated type constant-volume feeder which comprises an upright air cylinder, a connecting pipe below the piston rod end of the air cylinder, and a feeder body at the lower end of the connecting pipe. The directly operated type constant-volume feeder is characterized in that the air cylinder is connected with the connecting pipe by an air cylinder connecting flange, the connecting pipe passes through a center through hole of an feeder fixing seat in stationary fit, and a manhole for maintaining, dismantling and mounting the connection part of a piston rod of the air cylinder and the connecting rod of the feeder is formed in the pipe wall of the connecting pipe section above the feeder fixing seat and is used for fulfilling the purpose of split overhauling.

Description

The Direct Action Type constant-volume blanking device

Technical field

The utility model belongs in Aluminium Electrolysis aluminum oxide powder and electrolytical feeding device technical field on electrolyzer, and what relate generally to is a kind of Direct Action Type constant-volume blanking device.

Background technology

In Aluminium Electrolysis, constant-volume blanking device is indispensable a kind of blanking device on electrolyzer, the constant-volume blanking device used on the current electrolysis groove has multiple, all blanking devices role on electrolyzer is all consistent, and all can reach the demand of Aluminium Electrolysis, just structurally have any different, but the mode of connection of all blanking devices and electrolytic bath feed box is all the same Direct Action Type constant-volume blanking device as disclosed as Chinese patent ZL201120141447.2.The mode of connection of this blanking device is as follows: after blanking device is put into hopper, with double-screw bolt 9, blanking device permanent seat 3 is connected to compression with hopper 11 and gets final product.See Fig. 1,2.

Blanking device in use, is kept away unavoidable maintenance.The common fault of blanking device is material and the cylinder problem of leaking, no matter that is out of order, all must be by blanking device from whole taking-up maintenance hopper, and the material in hopper flows in electrolyzer in a large number, affects the steady running of electrolyzer, and maintenance intensity is large, length consuming time.

Although the Direct Action Type constant-volume blanking device has solved leakage material problem, maintenance mode is the same with other blanking device, as long as cylinder goes wrong, just whole taking-up of blanking device must be overhauled.Only have 9-12 month the work-ing life of any blanking device cylinder, the sealing member of partial cylinders will be changed after 3 months, and therefore, the repair rate of cylinder is higher.

Summary of the invention

The purpose of this utility model provides a kind of Direct Action Type constant-volume blanking device for existing weak point in above-mentioned prior art just.

The purpose of this utility model can realize by following technique measures:

Direct Action Type constant-volume blanking device of the present utility model comprises the cylinder of vertical setting, the pipe connecting that is arranged on cylinder piston rod end below and the blanking device body that is arranged on the pipe connecting lower end; Described cylinder is connected with pipe connecting by the cylinder joint flange, described pipe connecting is installed in the central through hole of blanking device permanent seat by the mode of heavy keying fit, on the tube wall that is positioned at the connection pipeline section above the blanking device permanent seat, offers for cylinder piston rod and blanking device connecting rod link position place are keeped in repair, the access opening of dismounting.

Access opening described in the utility model is comprised of two symmetrically arranged through holes; And in access opening, be embedded with rubber plug.

More specifically, Direct Action Type constant-volume blanking device of the present utility model is by the whole lengthening of pipe connecting on the disclosed technical foundation of Chinese patent ZL201120141447.2, the central through hole that the blanking device permanent seat is passed in the upper end of pipe connecting directly is connected with the cylinder piston rod end by the cylinder joint flange, and symmetry is opened two access openings on the tube wall that is positioned at the pipe connecting above the blanking device permanent seat, dismountable from here cylinder overhauls, and realizes the purpose of split maintenance.

The beneficial effects of the utility model are as follows:

The utility model has been realized the purpose of split maintenance by abovementioned technology, during the maintenance cylinder, do not need to adopt weight handling equipment (driving) that blanking device is hung out from integral body hopper, without blowing, can guarantee the steady running of electrolyzer due to hopper.In maintenance process, can save the repair time 70%, save manually 60%, reduce labour intensity 90%, make service work easily easy.
