Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis devices, in particular to an automatic soot blowing device for the crimping surface of an aluminum electrolysis anode guide rod. Background Art

[0002] In the process of electrolytic aluminum production, the anode aluminum guide rod is closely attached to the busbar to transmit current. Therefore, in the repeated use of the anode aluminum guide rod, the conductive surface of the anode aluminum guide rod (i.e. the surface attached to the anode busbar) needs to be ground and polished, and the impurity oxide layer on its surface needs to be removed to ensure that the contact resistance is reduced, the heat generation is reduced, and the energy consumption is reduced during the electrolytic aluminum production.

[0003] In the prior art, the crimping surface of the anode guide rod and the busbar is prone to increased compression and power consumption due to the large amount of dust, and sometimes manual processing is required, which is not conducive to the safe and stable operation of the electrolytic cell and also increases the labor intensity of employees. Therefore, the utility model proposes an automatic soot blowing device for the crimping surface of the aluminum electrolysis anode guide rod to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an automatic soot blowing device for the crimping surface of an aluminum electrolysis anode guide rod, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an automatic sootblowing device for the crimping surface of an aluminum electrolysis anode guide rod, comprising: an automatic sootblowing device body, a connecting block is arranged at the bottom of the automatic sootblowing device body, and a guide rod is arranged on the upper side of the connecting block.

[0006] An air guide iron pipe is sleeved on one side of the guide rod, a first clamping block is installed on the upper side of the air guide iron pipe, and a second clamping block is installed on the lower side of the first clamping block.

[0007] Preferably, the upper surface of the connection block is threadedly connected to one end of the stud, and the other end of the stud is threadedly connected to a nut.

[0008] Preferably, a base plate is provided between the nut and the connecting block, and the base plate is sleeved on the studs all around.

[0009] Preferably, the bottom plate and the guide rod are fixed by welding via a connecting plate, a positioning strip is fixedly mounted on the guide rod, and an air guide hole is opened on one side of the guide rod.

[0010] Preferably, the air guide iron pipe is slidably sleeved in the limiting sleeve, and the limiting sleeve is fixedly sleeved in the guide rod.

[0011] Preferably, one side of the first clamping block and the second clamping block is fixedly connected to the elbow clamp, and the elbow clamp is fixedly connected to the limiting sleeve by a hexagon socket screw.

[0012] Preferably, a sealing sleeve is sleeved on the air-conducting iron pipe, one side of the sealing sleeve abuts against the limiting sleeve, and the other side of the sealing sleeve abuts against the first clamping block and the second clamping block.

[0013] Preferably, one side of the first clamping block is fixedly connected to a limiting column, one side of the second clamping block is provided with a limiting hole, and the limiting column is slidably plugged into the limiting hole.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The air source of the third section of the big arm of the grab is fixedly connected with one end of the air guide iron pipe, and the other end of the air guide iron pipe is slidingly sleeved in the limit sleeve, and then the elbow clamp is adjusted to make the first clamp block and the second clamp block abut against the outer ring surface of the air guide iron pipe, and the limit column is inserted into the limit hole at the same time, so as to limit the first clamp block and the second clamp block. When the first clamp block and the second clamp block abut against the outer ring surface of the air guide iron pipe, the sealing sleeve on one side will be compressed to ensure the tightness of the air intake. After the grab is lowered, the air source when the grab is opened enters from the air guide iron pipe and is blown out from the air guide hole, so as to purge the contact surface between the anode busbar and the anode guide rod, effectively avoiding the increase of clamping pressure and power consumption due to the pressure joint surface of the anode guide rod and the busbar due to more dust, thereby improving the degree of automation and reducing the labor intensity of employees.
