Description

Technical Field

[0001] This solution belongs to the field of snow melting salt production, specifically involving a cleaning mechanism for a snow melting salt screening device. Background Technology

[0002] De-icing agents are chemicals that lower the melting temperature of ice and snow. Common de-icing agents are made from readily available and inexpensive raw materials, primarily composed of potassium acetate and chloride salts, and are classified based on these two components. De-icing agents melt snow on roads by lowering the melting temperature, facilitating road clearance.

[0003] A search revealed a utility model patent application with authorization announcement number CN205686716U, which discloses a production equipment for de-icing agents. This equipment includes a silo, belt scale, conveying device, corrosion inhibitor spraying device, roller press, high-pressure roller mill, screening machine, finished product packaging machine, and a return hopper elevator. The silo, belt scale, corrosion inhibitor spraying device, conveying device, roller press, high-pressure roller mill, screening machine, and finished product packaging machine are arranged sequentially. The return hopper elevator connects the screening machine and the roller press. This utility model's de-icing agent production equipment is simple, highly automated, and solves the problems of difficult demolding and rough particle surfaces in traditional roller extrusion granulation. The prepared de-icing agent particles have smooth surfaces, resulting in a smooth product surface and less powder generation due to inter-particle friction. Furthermore, the recycling of substandard de-icing agent particles saves raw material losses and improves the performance of the finished product.

[0004] In existing technologies, after the de-icing salt is screened, some de-icing salt will still remain on the screening machine. At this time, it is necessary to manually use a vacuum cleaner to collect and clean the remaining de-icing salt on the screening machine. However, the entire cleaning process is too labor-intensive for manual labor. At the same time, when the de-icing agent slides down the screen plate for screening, some de-icing agent will be embedded in the screen holes of the screen plate, making it impossible for the vacuum cleaner to quickly suck it out, resulting in incomplete cleaning. Utility Model Content

[0005] The purpose of this solution is to provide a cleaning mechanism for a snow-melting salt screening device to solve the problem that manual cleaning of the screening device is required in the existing technology, and at the same time solve the problem that the cleaning efficiency is too low by simply vacuuming.

[0006] To achieve the above objectives, this solution provides a cleaning mechanism for a snow-melting salt screening device, including a crossbeam. Both ends of the crossbeam are mounted on an installation mechanism. A U-shaped frame with an opening facing downwards is located below the crossbeam. An electric lifting rod is mounted on the top of the U-shaped frame and fixed to the crossbeam. A rotating roller is located on the inner side of the U-shaped frame, with its end rotatably connected to the U-shaped frame. A brush is mounted on the outer wall of the rotating roller, and a driving mechanism is located at one end of the roller. Dust collection hoods are located on both sides of the roller, with their ends connected to the U-shaped frame via connecting frames. A dust collection pipe is connected to the top of the dust collection hood, and the other end of the dust collection pipe is mounted on a fan. The fan is mounted on a dust collection box, which is installed on the top of the U-shaped frame.

[0007] The principle of this solution is as follows: When in use, the installation mechanism is first fixed on the top of both sides of the screening machine. After the screening machine finishes screening the de-icing salt, the electric lifting rod lowers the brush close to the screen plate of the screening machine. The installation mechanism will drive the brush and the dust collection hood to move in a straight line along the surface of the screen plate. During the movement, the drive mechanism drives the brush to rotate continuously, thereby cleaning the de-icing salt on the screen plate. The de-icing salt on the screen plate can be sucked into the dust collection hood by the fan and sent into the dust collection box along the dust collection pipe for collection, thus completing the operation of cleaning the de-icing salt remaining on the screening machine.

[0008] The technical advantages of this solution are as follows: by using a dust suction hood to move back and forth in a straight line along the surface of the screen plate of the screening machine, the residual de-icing salt on the screen plate can be quickly cleaned, eliminating manual labor. Furthermore, the continuously rotating brush can sweep out the de-icing salt embedded in the screen holes, thereby improving the cleaning effect and thoroughness of the equipment.

[0009] Furthermore, the brush is mounted on a sleeve, which is fitted onto the rotating roller, and the end of the sleeve is fixed to the rotating roller by bolts. The bolts securing the sleeve to the rotating roller facilitate the disassembly and replacement of the brush.

[0010] Furthermore, the bottom of the suction pipe is connected to a multi-port pipe, with branches of the multi-port pipe installed on the suction hood and connected to the inside of the suction hood. The multi-port pipe provides multiple air sources to the suction hood, thereby dispersing the suction effect of the suction hood on the de-icing salt, ensuring that the de-icing salt at different positions on the sieve plate is subjected to suction, thus improving the cleaning effect of the de-icing salt.

[0011] Furthermore, at least one guide shaft is provided parallel to the side of the electric lifting rod. The bottom of the guide shaft is fixed to the U-shaped frame, and the top of the guide shaft slides through the crossbeam. The guide shaft provides guidance for the lifting and lowering of the U-shaped frame, ensuring the stability of the lifting and lowering of the U-shaped frame.

[0012] Furthermore, the drive mechanism includes a first pulley, which is coaxially mounted on the end of the rotating roller. A second pulley is located above the first pulley and connected to the first pulley via a belt. A drive motor is mounted on the second pulley, and the drive motor is mounted on a U-shaped frame. The belt drive provides power to rotate the roller, and the drive motor can also be positioned above the U-shaped frame, allowing sufficient space for the length of the U-shaped frame to ensure that the length of the brush corresponds appropriately to the width of the screen plate.

[0013] Furthermore, the mounting mechanism includes two parallel, strip-shaped mounting frames. A linear motor is mounted on each frame on its opposite side, and a support column is mounted on each linear motor. The support column is fixed to the end of the crossbeam. The linear motors provide power for the movement of the brush and dust collection hood along the inclined direction of the sieve plate.

[0014] Furthermore, a detachable sealing door is installed on one side of the dust collection box. The dust collection box can be opened through the sealing door to remove the collected de-icing salt for secondary processing of the unscreened salt. Attached Figure Description

[0020] The reference numerals in the accompanying drawings include: mounting bracket 1, linear motor 2, support column 3, crossbeam 4, electric lifting rod 5, U-shaped frame 6, guide shaft 7, rotating roller 8, sleeve 9, brush 10, pulley one 11, belt 12, pulley two 13, drive motor 14, dust hood 15, multi-port pipe 16, suction pipe 17, fan 18, dust collection box 19, mounting mechanism 20, and drive mechanism 21. Detailed Implementation

[0021] The basic implementation examples are as follows: Figures 1-4As shown: A cleaning mechanism for a snow-melting salt screening device includes a crossbeam 4. Both ends of the bottom of the crossbeam 4 are mounted on an installation mechanism 20. The installation mechanism 20 includes two parallel, strip-shaped mounting frames 1. A linear motor 2 is mounted on each of the two mounting frames 1 on the side furthest from each other. A support column 3 is mounted on the linear motor 2. The support column 3 is fixed to the end of the crossbeam 4. The linear motor 2 provides power for the movement of the crossbeam 4 along the inclined direction of the screen plate. A U-shaped frame 6 with an opening facing downward is provided below the crossbeam 4. An electric lifting rod 5 is mounted on the top of the U-shaped frame 6. The electric lifting rod 5 is fixed to the crossbeam 4. At least one guide shaft 7 is provided parallel to the side of the electric lifting rod 5. The bottom of the guide shaft 7 is fixed to the U-shaped frame 6, and the top of the guide shaft 7 slides through the crossbeam 4. The guide shaft 7 provides guidance for the lifting and lowering of the U-shaped frame 6, ensuring the stability of the lifting and lowering of the U-shaped frame 6.

[0022] like Figure 2 and Figure 3 As shown, a rotating roller 8 is provided on the inner side of the U-shaped frame 6. The end of the rotating roller 8 is rotatably connected to the U-shaped frame 6. A brush 10 is installed on the outer wall of the rotating roller 8, and the brush 10 is mounted on a sleeve 9. The sleeve 9 is fitted onto the rotating roller 8, and the end of the sleeve 9 is fixed to the rotating roller 8 by bolts. The bolts fixing the sleeve 9 to the rotating roller 8 facilitate the disassembly and replacement of the brush 10. A drive mechanism 21 is provided at one end of the rotating roller 8. The drive mechanism 21 includes a pulley 11, which is coaxially mounted on the rotating roller. At the end of 8, above the first pulley 11, there is a second pulley 13. The second pulley 13 is connected to the first pulley 11 via a belt 12. A drive motor 14 is installed on the second pulley 13. The drive motor 14 is mounted on the U-shaped frame 6. Through the transmission of the belt 12, it provides power for the rotation of the rotating roller 8. At the same time, the drive motor 14 can be placed above the U-shaped frame 6 to leave sufficient space for the length of the U-shaped frame 6, ensuring that the length of the brush 10 and the width of the screen plate can be fully corresponded.

[0023] like Figure 1 and Figure 2As shown, dust collection hoods 15 are provided on both sides of the rotating roller 8. The ends of the dust collection hoods 15 are connected to the U-shaped frame 6 via connecting frames. A dust collection pipe 17 is connected to the top of the dust collection hoods 15, and a multi-port pipe 16 is connected to the bottom of the dust collection pipe 17. Branch pipes of the multi-port pipe 16 are installed on the dust collection hoods 15, and the multi-port pipe 16 communicates with the inside of the dust collection hoods 15. Through the arrangement of the multi-port pipe 16, multiple air sources are provided to the dust collection hoods 15, thereby dispersing the suction effect of the dust collection hoods 15 on the de-icing salt. The suction force is applied to the de-icing salt at different positions on the sieve plate, improving the cleaning effect of the de-icing salt. The other end of the suction pipe 17 is installed on the fan 18, which is set on the dust collection box 19. The dust collection box 19 is installed on the top of the U-shaped frame 6. A sealing door is detachably installed on one side of the dust collection box 19. The dust collection box 19 can be opened through the sealing door to take out the de-icing salt collected in the dust collection box 19 for secondary processing of the unscreened de-icing salt.

[0024] The specific implementation process of this utility model is as follows: When in use, the installation mechanism 20 is first fixed on the top of both sides of the screening machine. After the screening machine finishes screening the de-icing salt, the electric lifting rod 5 lowers the brush 10 close to the screen plate of the screening machine. The installation mechanism 20 will drive the brush 10 and the dust suction hood 15 to move in a straight line along the surface of the screen plate. During the movement, the drive mechanism 21 drives the brush 10 to rotate continuously, thereby cleaning the de-icing salt on the screen plate. The de-icing salt on the screen plate can be sucked into the dust suction hood 15 by the fan 18 and sent into the dust collection box 19 along the dust suction pipe 17 for collection, thus completing the operation of cleaning the de-icing salt remaining on the screening machine.

[0025] This solution uses a dust suction hood 15 to move linearly back and forth along the surface of the screen plate of the screening machine, which can quickly clean the de-icing salt remaining on the screen plate, saving manual labor. In addition, the continuously rotating brush 10 can sweep out the de-icing salt embedded in the screen holes of the screen plate, thereby improving the cleaning effect and thoroughness of the equipment.
