Description

Technical Field

[0001] The utility model relates to the technical field of magnesium alloy material casting, in particular to a cleaning device for a magnesium alloy smelting crucible. Background Art

[0002] Magnesium alloy material is an alloy composed of magnesium metal as the matrix and other elements. It is the lightest metal structural material in practical application. It has many advantages such as low density, high strength, damping, good machinability and casting performance. With the lightweight development trend of aerospace, transportation, and 3C products, magnesium alloy as a new material is not only light but also environmentally friendly. It is one of the new alloy materials currently popular in various industries. At present, the production of deformable magnesium alloy materials adopts a semi-continuous casting process. The specific process is to put the magnesium ingot to be melted in the crucible of the melting furnace, melt the magnesium ingot all at once, and then directly add other alloy elements in the form of pure metal or intermediate alloy into the magnesium melt. However, the crucible needs to be cleaned before smelting. The purpose of cleaning is to prevent the increase of impurity content in the alloy on the one hand, and to remove non-metallic and gaseous inclusions in some crucible seams on the other hand.

[0003] At present, the process of cleaning crucibles in factories is as follows: first, the furnace is baked. When baking the furnace, the crucible is heated until the inner wall is dark red, and then the solvent is sprinkled in the crucible. The reaction generated by the melting process of the flux is used to bring some impurities into the bottom of the pot. Then the worker uses a shovel to scrape the impurities attached to the inner wall of the crucible. After scraping, the worker uses a crane to lift the crucible and move it to an unmanned place. The worker hooks the edge of the crucible with an iron hook, reverses the crucible, and pours the magnesium liquid and slag liquid in the pot into the designated position. This process usually requires 2 to 3 people to complete. Therefore, at this stage, the factory has a low degree of automation in cleaning magnesium alloy smelting crucibles, and basically relies on manual cleaning. The temperature of the crucible can be as high as 600°C when the furnace is baked. The disadvantage of manual cleaning is that the environment in which the workers scrape is harsh and dangerous. In addition, the cleaning efficiency of the crucible is relatively low in harsh environments, and the cleaning quality is difficult to control.

[0004] To this end, the utility model proposes an automatic cleaning device for magnesium alloy smelting crucibles, which solves the problem of low automation of magnesium alloy crucible cleaning in the prior art by adding a moving device, a cleaning device and a collecting device, and also reduces the operating procedures of workers to achieve the purpose of automatic cleaning.

[0037] The following is a detailed description of the method for using the automatic cleaning device for magnesium alloy melting crucible, which includes the following steps:

[0038] Step 1: When starting to clean the crucible, you first need to limit the screw linear lift mechanism. According to the characteristics of the magnesium alloy smelting crucible, it is generally cleaned from the bottom upwards. The worker uses the handle to push the entire device to the top of the crucible, and then starts the switch of the screw linear lift mechanism. The screw linear lift mechanism begins to move, and the screw linear lift mechanism drives the cross plate to move. The cross plate starts to descend from the highest point, and the descending movement of the cross plate drives the brush to descend. During the descent of the brush, it passes through the round hole on the bottom plate and enters the crucible as it descends. When it lands at the bottom of the crucible, the linear screw lift can be closed and the rotating mechanism can be turned on. When the rotating mechanism rotates at high speed, the brush begins to scrub the area covered by it.

[0039] Step 2. After the brush has scrubbed the bottom of the crucible, start the screw linear lifting frame mechanism to rise. By reading the scale of the screw linear lifting frame mechanism, judge the displacement of the brush rising. When the brush rises to a certain position, close the screw linear lifting frame mechanism, and then turn on the rotating mechanism. The brush starts to rotate at high speed to scrub. Repeat this step so that the crucible wall covered by the solution can be scrubbed. After scrubbing, if there are places that are difficult to scrub, scrub them vigorously. The impurities on the inner wall of the crucible can be removed by adjusting the speed of the motor to increase the rotation speed. After cleaning, start the screw linear lifting mechanism to start rising, and the cross plate drives the brush to move upward and return to its initial position.

[0040] Step three, after cleaning, start collecting the waste liquid of magnesium liquid or solvent in the crucible. First, place the free end of the water inlet pipe in the crucible, open the buckle, and place the stored water inlet pipe into the crucible cleaning waste liquid. After placing the water outlet pipe, start the centrifugal pump and use the centrifugal pump to extract the waste liquid of magnesium liquid or solvent in the crucible. The waste liquid of magnesium liquid or solvent is pumped into the wastewater collection box through the water outlet pipe, the centrifugal pump and the water inlet pipe, and wait for the waste liquid to be pumped out.

[0041] Step 4. After the waste liquid is extracted, wait for the temperature of the water outlet pipe to drop to a touchable state. The water outlet pipe can be put into the buckle, and the handle can be used to push the entire device to the waste liquid recovery area. Turn on the faucet to drain the waste liquid to the designated location.

[0042] The present invention discloses an automatic cleaning device for magnesium alloy melting crucibles, which is used to solve the problems existing in the manual cleaning process of the existing magnesium alloy melting crucibles, such as poor safety of manual cleaning in harsh environments, difficulty in ensuring cleaning quality, low cleaning efficiency and high labor intensity. In view of the above problems, the present invention sets a lifting device and a rotating device on the mobile device, controls the height of the brush block by the lifting device, and at the same time, uses the rotating device to rotate the brush block at high speed to realize the automatic cleaning of the crucible, which greatly reduces the labor intensity of the workers. In the cleaning process, the mobile device is located at the top of the crucible, which improves the safety of the workers. Secondly, the brush on the cleaning device is controlled by the control console to reduce the participation of human labor, which can ensure the quality and efficiency of the cleaning of the magnesium alloy melting crucible; at the same time, the in-situ cleaning is performed without moving the crucible, which not only reduces the probability of damage to the crucible and surrounding equipment during the moving process, but also improves the working environment of the workers. The automatic cleaning device is simple and convenient to operate, and can be completed by only one person, reducing labor costs.
