Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum electrolysis production, and particularly relates to a device for transferring liquid electrolyte used in aluminum electrolysis production. Background Art

[0002] Electrolytic aluminum plays a very important role in industrial production. The cryolite-aluminum oxide salt electrolysis method was initially invented at the end of the 19th century. During the development process of up to a hundred years, it has been used by aluminum production manufacturers all over the world and is widely applied to the aluminum electrolysis industry in various regions of the world. The cryolite-aluminum oxide molten salt acts as an electrolyte throughout the electrolysis process. By dissolving the aluminum oxide contained in the electrolyte, an electrochemical reaction occurs to produce aluminum liquid.

[0003] In industrial production, the electrolyte composition is complex, including cryolite, aluminum fluoride, aluminum oxide, calcium fluoride, lithium fluoride, etc. In theory, the electrolyte does not participate in the electrochemical reaction and will not be consumed. However, in actual production, the height of the electrolyte will change due to various factors. The height of the electrolyte has a great influence on the operation of the electrolytic cell and even determines the quality of the finally produced aluminum product. Therefore, it is necessary to strictly control the height of the electrolyte, which is generally maintained at 18 cm to 22 cm. The height of the electrolyte often changes due to changes in the molecular ratio, superheat degree, electrolysis temperature, aluminum oxide concentration, etc. When it exceeds the control range, corresponding adjustments need to be made, and the transfer of liquid electrolyte is involved in the specific operation. The usual practice is to transfer the liquid electrolyte in the electrolytic cell with a high electrolyte level to the electrolytic cell with a low electrolyte level. During the operation process, there are difficulties in pouring out the liquid electrolyte in the liquid container and safety risks of scalding caused by splashing of high-temperature liquid. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for transferring liquid electrolyte used in aluminum electrolysis production to solve the above problems.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A device for transferring liquid electrolyte used in aluminum electrolysis production includes a vehicle body, an adjusting mechanism support, an adjusting mechanism, an electrolyte barrel, a counterweight, and a handrail; the vehicle body includes symmetrically arranged wheels and axles provided on the wheels.

An adjusting mechanism support is arranged on the top of the cross beam. The adjusting mechanism support includes vertical support rods symmetrically arranged on the top of the cross beam. A horizontal support rod is arranged between the vertical support rods. The electrolyte barrel is arranged at the end of the front support rod far from the cross beam.

[0007] In order to further realize the utility model, the electrolyte barrel has symmetrical barrel ears on both sides, and movable slots are respectively arranged on the front support rods, and the barrel ears are clamped in the movable slots.

[0008] In order to further realize the utility model, a fixed pull ring is provided at one end of the electrolyte barrel near the crossbeam, and the adjustment mechanism includes an adjustment rod, a rotating sleeve, a movable pull rod and a control handle. The rotating sleeve is sleeved on the outer periphery of the horizontal support rod, and a bending portion is provided in the middle of the adjustment rod and is mounted on the rotating sleeve. A movable pull rod is provided at one end of the adjustment rod near the electrolyte barrel, and movable rings I and II are provided at both ends of the movable pull rod, respectively. The movable ring I is rotatably connected to the adjustment rod, and the movable ring II is sleeved on the fixed pull ring. The fixed pull ring is fixedly connected to the barrel wall, and the connection point is in the vertical direction of the midpoint of the line connecting the two ears, which is lower than half of the height of the barrel body. The setting of the size and position of the above components and connection points ensures that the liquid electrolyte barrel can flexibly rotate in the movable slot and will not automatically tip over, and the barrel can be smoothly tipped over to pour out the liquid electrolyte when the adjustment mechanism is operated.

[0009] In order to further realize the utility model, the angle between the front support rod and the rear connecting rod is less than 150°. The setting of this angle is to ensure that the operator can easily control the rise or fall of the rear of the vehicle when the device is used, thereby controlling the rise and fall of the electrolyte barrel.

[0010] In order to further realize the utility model, reinforcing rods are symmetrically arranged on both sides of the cross beam, one end of the reinforcing rod is fixedly connected to the movable slot, and the other end is fixedly connected to the connection between the rear connecting rod and the vertical rod. The reinforcing rod is arranged to improve the overall stability of the vehicle body.

[0011] In order to further realize the utility model, the distance between the vertical support rods is smaller than the length of the crossbeam, the horizontal support rod is in the shape of a round rod, and the two ends of the horizontal support rod are respectively inserted into the top of the vertical support rod.

[0012] In order to further realize the utility model, the movable slot is in a "U" shape with the opening facing in the direction of the liquid electrolyte barrel.

[0013] In order to further realize the utility model, the barrel ear is a round rod structure, the barrel ear is set above 1 / 2 of the barrel body height of the electrolyte barrel, and the fixed pull ring is set below 1 / 2 of the barrel body height of the electrolyte barrel. It is ensured that the electrolyte barrel will not be separated from the vehicle body and can be tilted forward and backward along the axis of the entire device.

[0014] In order to further realize the utility model, the moment between the counterweight and the axle is smaller than the moment between the electrolyte barrel and the axle when the electrolyte barrel is filled with liquid.

[0015] To further implement the present utility model, the armrest includes vertically arranged rods symmetrically disposed and a cross bar at the end of the vertically arranged rods. One ends of the vertically arranged rods away from the cross bar are respectively connected to the rear connecting rods, and the angle between the vertically arranged rods and the rear connecting rods is not less than 150°.

[0016] The beneficial effects of the present utility model compared with the prior art are as follows:

[0017] The function of the adjusting mechanism bracket is to provide a fulcrum for the adjusting mechanism to achieve the purpose of tilting the electrolyte barrel through the adjusting mechanism; the horizontal support rod is in the shape of a round bar to provide a support for the adjusting mechanism to rotate around the top end of the adjusting mechanism bracket. The entire adjusting mechanism is connected in series with the electrolyte barrel, that is, by pressing or lifting the control handle, the rotating sleeve of the adjusting mechanism rotates around the cross bar of the bracket, the front end of the adjusting rod moves up and down, driving the movable pull rod to move up and down, further driving the fixed pull ring at the bottom of the barrel wall, so that the electrolyte barrel tilts to pour out the liquid electrolyte. The settings of the movable ring Ⅰ and the movable ring Ⅱ are to ensure the movable connection between the adjusting mechanism and the electrolyte barrel, prevent jamming, and ensure smooth operation.

[0018] To ensure the overall strength of the vehicle body, the cross beam is made of channel steel with a wall thickness of not less than 3 mm, the front support rod and the rear connecting rod are made of steel bars with a diameter of not less than 30 mm, and the reinforcing rod is made of steel bars with a diameter of not less than 20 mm. Because when this device is in use, the electrolyte barrel is filled with electrolyte liquid, which will generate a large moment, and at the same time it is in contact with a high-temperature environment. The above size settings can fully ensure the safety of the device.

[0019] The device of the present utility model has a simple structure and a low manufacturing cost. Ordinary technicians in the field of aluminum electrolysis production technology can fabricate it by themselves according to the technical solution.

[0020] The usage method of the present utility model is simple. Technicians in this industry can understand and apply it to aluminum electrolysis production according to the technical solution;

[0021] Through the implementation of the present utility model, the pouring operation of the liquid electrolyte between electrolytic cells is convenient, easy, efficient and safe. When the operator takes the electrolyte, the electrolyte barrel can be easily moved to the front of the electrolytic cell. When moving the barrel filled with liquid electrolyte, only a small force is required, and at the same time, the operator is far away from the barrel body. When pouring the electrolyte, the electrolyte barrel can also be easily tilted, which not only reduces the labor intensity and improves the work efficiency, but also avoids the scalding of personnel caused by the overflow or splash of the liquid electrolyte.
