Abstract
The utility model discloses a slag dragging device, which relates to the improvement for the slag dragging device in the production of electrolytic aluminum, in particular to the improvement for a pneumatic controlling device in the slag dragging device. The utility model provides the slag dragging device which has high production efficiency and locking function. The utility model comprises a supporting frame, and a self-locking air cylinder arranged on the supporting frame is mutually connected with the axle of a grab bucket through a connecting rod; the air cylinder of the self-locking air cylinder is mutually connected with an air passage through two throttling valves and a three-position five-way valve respectively; the locking cavity of the self-locking air cylinder is mutually connected with the air passage through a pressure relay and two-position three-way valve; the utility model has the structural key point that the air cylinder of the self-locking air cylinder is mutually connected with the air passage through the three-position five-way valve.
Description
Technical field:
The utility model relates to the improvement of device for dragging dregs in the Aluminum Electrolysis Production; Especially relate to the improvement of air control unit in the device for dragging dregs.
Background technology:
In the Aluminum Electrolysis Production process, the ionogen waste material (slag) that electrolytic aluminum produces needs to pick up with device for dragging dregs at any time, transports to then and concentrates reason everywhere.But in dragging for the slag process, often there is waste material to adhere in the grab bucket of device for dragging dregs, influenced production efficiency; In addition, in the air control unit of device for dragging dregs, locking latches is not set usually, grab bucket is closed and be can not get guaranteeing, therefore, in the operational process of grab bucket with crane, has potential safety hazard.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of production efficiency height is provided, and has the device for dragging dregs of locking function.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises bracing frame, and the self-locking cylinder on the bracing frame links to each other by the axle of connecting rod with grab bucket; The cylinder of self-locking cylinder links to each other with gas circuit by two throttling valve, a three position five-way valve respectively; The lock chamber of self-locking cylinder links to each other with gas circuit by pressure relay, two position three-way valve; Its structural feature is that the cylinder of self-locking cylinder links to each other with gas circuit by three position five-way valve.
The beneficial effects of the utility model:
1, enhance productivity:
Because the cylinder of the utility model self-locking cylinder links to each other with gas circuit by three position five-way valve; Just can realize the quick opening and closing (the continuous rapping of grab bucket) of grab bucket by this device, make grab bucket go up adherent ionogen waste material and come off; Be beneficial to the non-stop run effectively of grabbing bucket, improved production efficiency;
2, security is good:
Because the utility model adopts self-locking cylinder (for example, the CLSD250 self-locking cylinder of Japanese SNC), this cylinder requires to unblank earlier afterwards to move, and can prevent operator's flase operation; Realize any position locking, guarantee the closing condition of grabbing bucket, avoided potential safety hazard.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a pneumatic control schematic diagram of the present utility model.
Embodiment:
The utility model comprises bracing frame 16, and the self-locking cylinder 13 on the bracing frame 16 links to each other by the axle 11 of connecting rod 12 with grab bucket 10; The cylinder 14 of self-locking cylinder 13 links to each other with gas circuit 5 by two throttling valve 4, a three position five-way valve 2 respectively; The lock chamber 15 of self-locking cylinder 13 links to each other with gas circuit 5 by pressure relay SP, two position three-way valve 1; The cylinder 14 of self-locking cylinder 13 links to each other with gas circuit 5 by three position five-way valve 3.
Self-locking cylinder 13 adopts the CLSD250 of Japanese SNC; Can purchase from market.
Below in conjunction with a description of drawings course of action of the present utility model:
At first, the rly. 5DT of two position three-way valve 1 gets electric, and position, two position three-way valve 1 left side is logical, and lock chamber 15 internal gas pressures of self-locking cylinder 13 raise, and lock is opened; When air pressure was elevated to 0.4MPa, pressure relay SP sent signal, allowed grab bucket 10 to carry out next step action.When the rly. 3DT of three position five-way valve 2 gets when electric, grab bucket 10 opens, and descend; When the rly. 4DT of three position five-way valve 2 gets when electric, grab bucket 10 is closed, and grabs bucket this moment 10 to grab full ionogen waste material; When the rly. 5DT of two position three-way valve 1 outage, two position three-way valve 1 right position is logical, and lock chamber 15 internal gas pressures reduce, locking grab bucket 10; Grab bucket then and 10 rise, crane drives grab bucket 10 behind the predetermined position, and grab bucket 10 descends; The rly. 3DT of three position five-way valve 2 gets electric, and grab bucket 10 is opened, and topples over the ionogen waste material; The rly. 1DT of three position five-way valve 3 gets electric, and grab bucket 10 is opened fast; Rly. 2DT gets electric, and grab bucket 10 is closed fast; Realize the rapping of grab bucket 10.
