Description

Technical Field

[0001] This invention relates to the field of dust removal, and in particular to a wet dust removal device, an integrated grinding workstation, and a dust removal method. Background Technology

[0002] The core principle of wet scrubbing equipment is to use liquid as a medium to capture and separate pollutants in gas, such as dust, soot, and oil mist. It mainly achieves purification through mechanisms such as inertial collision, interception, diffusion, and agglomeration: when the dust-laden airflow impacts the liquid surface or passes through the droplet layer, larger dust particles are released from the airflow due to inertia and are captured after colliding with the droplets or liquid film; fine dust is captured because it is intercepted by the droplets or diffuses to the surface of the droplets through Brownian motion. In short, this equipment uses water to adhere to and encapsulate dust in the air, and then uses water to carry it away, thus achieving gas-dust separation.

[0003] In grinding workstations, the application of wet scrubbing equipment is crucial. Grinding, polishing, and cutting processes generate large amounts of metal dust, which not only harms worker health but also poses an explosion risk. Wet scrubbing equipment is the preferred choice due to its unique advantages, including excellent explosion-proof performance and efficient handling of high-concentration, heavy-particle dust generated during grinding.

[0004] The existing technology also has the following drawbacks:

[0005] After a wet dust collector captures a large amount of dust, the water contains a lot of impurities, which need to be filtered. After filtering for a period of time, the filter cartridge needs to be cleaned to prevent clogging. Cleaning is quite troublesome. The cleaning equipment set inside the filter cartridge, especially the cleaning brush, will get contaminated with impurities during the filtration process, resulting in a decrease in cleaning effect.

[0006] Therefore, this application provides a wet dust removal device, an integrated grinding workstation, and a dust removal method to meet the requirements. Summary of the Invention

At the same time, the cleaning brush is located in the cleaning strip hole, and the sealing strip closes the cleaning strip hole to prevent impurities in the separation tank from contaminating the cleaning brush and ensuring the cleaning effect of the cleaning brush. In the cleaning mode, the sealing strip and the cleaning brush move, and the cleaning brush and the separation tank rotate in opposite directions to brush off the impurities on the inner wall of the separation tank, preventing the inner wall of the separation tank from becoming clogged and improving the continuous separation effect of the separation tank.

At the same time, the cleaning brush is located in the cleaning strip hole, and the sealing strip closes the cleaning strip hole to prevent impurities in the separation tank from contaminating the cleaning brush and ensuring the cleaning effect of the cleaning brush. In the cleaning mode, the sealing strip and the cleaning brush move, and the cleaning brush and the separation tank rotate in opposite directions to brush off the impurities on the inner wall of the separation tank, preventing the inner wall of the separation tank from becoming blocked and improving the continuous separation effect of the separation tank. The separation and cleaning functions do not interfere with each other.

[0027] 2. In this invention, the back spray pipe is connected to an external high-pressure water source to deliver clean water to the back spray shell. The back spray shell is fixed on the support frame and sprays high-pressure water into the outer wall of the separator tank through the nozzle.

In conjunction with the rotation of the separator tank, the outer wall of the separator tank is thoroughly cleaned.

[0028] 3.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1: Reference Figures 1-12 The wet dust removal equipment shown includes a spray assembly 3, an input pipe 2, and a treatment tank 1. A separation tank 4 is installed inside the treatment tank 1. The spray assembly 3 can spray water curtains to intercept dust in the air and let it flow into the separation tank 4. The separation tank 4 has separation holes and cleaning strip holes. A cleaning assembly 5 is installed inside the cleaning strip holes. The bottom of the treatment tank 1 is connected to a liquid outlet pipe 7. The bottom of the separation tank 4 is connected to a sewage discharge pipe 6. The cleaning assembly 5 includes a sealing strip 51 and a cleaning brush 52.

[0045] The processing tank 1 can switch between processing mode and cleaning mode. When the processing tank 1 is in processing mode, the liquid outlet pipe 7 is open, the sewage pipe 6 is closed, the sealing strip 51 abuts against the inner wall of the separation tank 4, and the cleaning brush 52 is located in the cleaning strip hole. When the processing tank 1 is in cleaning mode, the liquid outlet pipe 7 is closed, the sewage pipe 6 is open, the sealing strip 51 moves away from the inner wall of the separation tank 4, and drives the cleaning brush 52 to be located on the inner wall of the separation tank 4.

[0046] The separation tank 4 is equipped with a drive assembly 8, which can drive the separation tank 4 and the cleaning brush 52 to rotate, and the rotation directions of the separation tank 4 and the cleaning brush 52 are opposite.

[0047] The spray assembly 3 generates a water curtain to capture dust in the air. The dust-laden water flows through the input pipe 2 into the separation tank 4. The separation tank 4 achieves solid-liquid separation through the separation hole. The liquid is discharged through the liquid outlet pipe 7, and impurities are trapped inside the tank. The sealing strip 51 and cleaning brush 52 of the cleaning assembly 5 are integrated into the cleaning strip hole, realizing the switching between two working modes. In the processing mode, the sealing strip 51 seals the inner wall of the separation tank 4, the cleaning brush 52 is stored in the cleaning strip hole, the liquid outlet pipe 7 is open and the drain pipe 6 is closed. In the cleaning mode, the sealing strip 51 is removed, the cleaning brush 52 extends to the inner wall of the separation tank 4, the liquid outlet pipe 7 is closed and the drain pipe 6 is opened. The drive assembly 8 drives the separation tank 4 and the cleaning brush 52 to rotate in opposite directions, achieving efficient cleaning through relative motion.

[0048] In the processing mode, the separator 4 separates wastewater and impurities for convenient subsequent treatment. At the same time, the cleaning brush 52 is located inside the cleaning strip hole, and the sealing strip 51 seals the cleaning strip hole to prevent impurities inside the separator 4 from contaminating the cleaning brush and to ensure the cleaning effect of the cleaning brush 52. In the cleaning mode, the sealing strip 51 and the cleaning brush 52 move, and the cleaning brush 52 and the separator 4 rotate in opposite directions to brush off the impurities on the inner wall of the separator 4, preventing the inner wall of the separator 4 from becoming clogged and improving the continuous separation effect of the separator 4. The separation and cleaning functions do not interfere with each other.

[0049] The input pipe 2 is fixedly installed on the processing tank 1 and communicates with the processing tank 1. The separation tank 4 is rotatably connected inside the processing tank 1, and the top of the separation tank 4 is set as an opening.

[0050] The top opening design allows the dust-laden water captured by the spray assembly 3 to directly enter the interior of the separation tank 4.

[0051] Example 2, refer to Figures 1-12 Unlike the above embodiments, the drive assembly 8 includes a drive rod 801, a cleaning drive gear 802, a transfer gear 803, and a separation drive gear 804. The drive rod 801 can rotate, the separation drive gear 804 can drive the sealing strip 51 and the cleaning brush 52 to rotate on the inner wall of the separation tank 4, and the separation drive gear 804 can drive the separation tank 4 to rotate.

[0052] The drive rod 801 rotates, which drives the separation drive gear 804 to rotate. The separation drive gear 804 directly drives the separation tank 4 to rotate. At the same time, through the transmission of the cleaning drive gear 802 and the intermediate gear 803, the sealing strip 51 and the cleaning brush 52 are driven to move, and the separation tank 4 and the cleaning brush 52 rotate in opposite directions to achieve relative movement to enhance the cleaning effect.

[0053] The drive assembly 8 also includes a support frame 805, a drive motor 806, a drive pulley, a driven pulley, a drive belt, a separation drive gear ring 807, and a cleaning drive gear ring 808. The support frame 805 is fixedly mounted on the processing tank 1, the drive motor 806 is fixedly mounted on the support frame 805, the drive pulley is fixedly mounted on the output end of the drive motor 806, the driven pulley is fixedly mounted on the drive rod 801, the drive belt connects the drive pulley and the driven pulley, the cleaning drive gear 802 is rotatably connected to the support frame 805, the separation drive gear ring 807 is fixedly mounted on the separation tank 4, the separation drive gear 804 meshes with the separation drive gear ring 807, the cleaning drive gear ring 808 is rotatably connected to the middle of the separation tank 4, and the intermediate gear 803 meshes with the cleaning drive gear ring 808.

[0054] The drive motor 806 drives the active pulley to rotate, the active pulley drives the drive belt to rotate, the drive belt causes the passive pulley to rotate, the passive pulley drives the drive rod 801 to rotate, the drive rod 801 drives the separation drive gear 804 to rotate, the separation drive gear 804 drives the separation drive gear ring 807 to rotate, and the separation drive gear ring 807 drives the separation tank 4 to rotate.

[0055] The drive assembly 8 also includes a rectangular drive block 809, a rectangular drive cylinder 810, a movable plate 811, a switching cylinder 812, a fixed plate, and a pressure spring 813. The rectangular drive block 809 is fixedly mounted on the drive rod 801. The rectangular drive cylinder 810 is slidably fitted on the rectangular drive block 809. The movable plate 811 is rotatably connected to the rectangular drive cylinder 810. The cleaning drive gear 802 is fixedly mounted on the rectangular drive cylinder 810. The switching cylinder 812 is fixedly mounted on the support frame 805. The fixed plate is fixedly mounted on the output end of the switching cylinder 812. One end of the pressure spring 813 is fixedly mounted on the fixed plate, and the other end of the pressure spring 813 is fixedly mounted on the movable plate 811.

[0056] When the separator tank 4 is in processing mode, the cleaning drive gear 802 disengages from the intermediate gear 803, and the drive rod 801 only drives the separator tank 4 to rotate. Because the sealing strip 51 abuts against the separator tank 4, the sealing strip 51 and the cleaning brush 52 rotate together with the separator tank 4, causing the separator tank 4 to rotate and generate centrifugal force, which quickly discharges water from the inner wall and improves processing capacity. When the separator tank 4 is in cleaning mode, the switching cylinder 812 drives the moving plate 811 to descend through the clamping spring 813. The moving plate 811 drives the rectangular drive cylinder 810 to descend. The rectangular drive cylinder 810 descends on the rectangular drive block 809, and the rectangular drive cylinder 810 drives the cleaning drive... The moving gear 802 rotates, and the cleaning drive gear 802 moves downward to mesh with the intermediate gear 803. The drive rod 801 drives the rectangular drive block 809 to rotate, the rectangular drive block 809 drives the rectangular drive cylinder 810 to rotate, the rectangular drive cylinder 810 drives the cleaning drive gear 802 to rotate, the cleaning drive gear 802 drives the cleaning drive gear ring 808 to rotate, the cleaning drive gear ring 808 drives the fixed block 55 and the connecting block 54 to rotate, the connecting block 54 drives the sealing strip 51 and the cleaning brush 52 to rotate. The cleaning brush 52 rotates in the opposite direction to the rotation of the separation tank 4, and the cleaning brush 52 rotates on the inner wall of the separation tank 4 to brush off the impurities on the inner wall of the separation tank 4.

[0057] The compression spring 813 provides constant pressure to ensure that the cleaning drive gear 802 and the intermediate gear 803 mesh tightly and to avoid rigid impact during gear meshing. When the cleaning drive gear 802 and the intermediate gear 803 mesh, the speed of the drive motor 806 is reduced, making it easier for them to mesh.

[0058] The cleaning drive gear ring 808 is rotatably connected to the middle of the separator tank 4, dividing the separator tank 4 into upper and lower parts. Separation drive gear rings 807 are fixedly installed on both the upper and lower parts. Two separation drive gears 804 are fixedly installed on the drive rod 801, which mesh with the two separation drive gear rings 807 respectively.

[0059] Example 3, referring to Figures 1-12 Unlike the above embodiments, the cleaning component 5 also includes a drive push rod 53, a connecting block 54, a fixing block 55, and a sliding block 56. The drive push rod 53 is fixedly installed on the inner wall of the cleaning drive gear ring 808, the connecting block 54 is fixedly installed on the output end of the drive push rod 53, the sealing strip 51 is fixedly installed on the connecting block 54, the cleaning brush 52 is fixedly installed on the sealing strip 51, the fixing block 55 is fixedly installed on the inner wall of the cleaning drive gear ring 808, and a sliding groove is provided on the fixing block 55, and the sliding block 56 is slidably engaged in the sliding groove.

[0060] The drive push rod 53 of the cleaning component 5 generates linear motion, which drives the sealing strip 51 and the cleaning brush 52 to move along the sliding groove of the fixed block 55 through the connecting block 54, so that the cleaning brush 52 moves out from the cleaning strip hole and is located on the inner wall of the separation tank 4. The rotational motion of the cleaning drive gear ring 808 drives the cleaning brush 52 to make a circular motion around the inner wall of the separation tank 4 for cleaning.

[0061] The cleaning assembly 5 also includes two back-spray shells 57 and a back-spray pipe 58. The back-spray shells 57 are fixedly mounted on the support frame 805, and the back-spray pipe 58 is fixedly mounted on the side of the back-spray shells 57 and communicates with the back-spray shells 57. The back-spray pipe 58 is set through the treatment tank 1.

[0062] The back spray pipe 58 is connected to an external high-pressure water source to deliver clean water to the back spray shell 57. The back spray shell 57 is fixed on the support frame 805 and sprays high-pressure water into the outer wall of the separator 4 through the nozzle. This forms a coordinated cleaning process with the internal cleaning brush 52, cleaning the impurities in the separation holes of the separator 4 and improving the cleaning capacity. In conjunction with the rotation of the separator 4, the outer wall of the separator 4 is thoroughly cleaned.

[0063] Example 4, refer to Figures 1-12 The difference from the above embodiment is that a connecting pipe is fixedly installed at the bottom of the treatment tank 1, and a drain pipe 6 is fixedly installed at the bottom of the separation tank 4. The drain pipe 6 is rotatably connected to the connecting pipe. The connecting pipe passes through the treatment tank 1 and extends outward. A drain solenoid valve is installed on the connecting pipe, and a liquid outlet solenoid valve is installed on the liquid outlet pipe 7.

[0064] The connecting pipe at the bottom of the treatment tank 1 serves as a rotational support for the drain pipe 6. The drain pipe 6 forms a sealed rotational connection with the connecting pipe through a rotary joint, ensuring that the drain channel is unobstructed when the separation tank 4 rotates.

[0065] Example 5, refer to Figures 1-12 Unlike the above embodiments, the spray assembly 3 includes a fan 31, a spray shell 32, a water curtain generator 33, and a water tank 34. An air intake channel is provided inside the spray shell 32. The fan 31 is fixedly installed on the spray shell 32 and communicates with the air intake channel. The water curtain generator 33 is installed inside the air intake channel. The spray shell 32 is connected to the water tank 34. A water pump is installed inside the water tank 34 and is connected to the input pipe 2.

[0066] The spray assembly 3 uses a fan 31 to generate negative pressure, drawing dust-laden air into the duct. The water curtain generator 33 forms a high-density water curtain within the duct, where dust particles collide with and are captured by water droplets, forming dust-laden water that flows into the water storage tank 34. The water pump in the water storage tank 34 pressurizes the dust-laden water and pumps it through the input pipe 2 into the separation tank 4 for solid-liquid separation, achieving water recycling.

[0067] Furthermore, the water curtain generator 33 includes several spray heads, which are connected to an external water source to spray cleaning water through the spray heads.

[0068] Example 6, refer to Figures 1-12 Unlike the above embodiments, an integrated grinding workstation uses the aforementioned wet dust removal equipment, including a negative pressure housing 9, a feeding assembly 10, a grinding robot 11, and a grinding wheel 12. The feeding assembly 10 can transport the workpiece into the negative pressure housing 9, the grinding robot 11 can clamp the workpiece on the feeding assembly 10 and move it to the position of the grinding wheel 12, the grinding wheel 12 can rotate to grind the workpiece, a grinding motor is installed on the negative pressure housing 9, and the grinding wheel 12 is connected to the output end of the grinding motor.

[0069] The feeding assembly 10 includes a transfer base 101 and two sets of transfer units. Each transfer unit includes a transfer track 102, a transfer push rod 103, a transfer frame 104, and a workpiece storage tray 105. The transfer track 102 is fixedly installed on the transfer base 101, and the transfer frame 104 is slidably fitted on the transfer track 102. The output end of the transfer push rod 103 is fixedly installed on the transfer frame 104, and the workpiece storage tray 105 is fixedly installed on the transfer frame 104. The transfer frames in the two transfer units have different heights.

[0070] The grinding robot 11 clamps the workpiece and moves it to the position of the grinding wheel 12. The grinding motor drives the grinding wheel 12 to rotate, and the grinding wheel 12 grinds the workpiece. The grinding robot 11 is existing technology and will not be described in detail here.

[0071] The workpiece is placed on the workpiece storage tray 105. The transfer push rod 103 drives the transfer frame 104 and the workpiece storage tray 105 to move, moving the workpiece storage tray 105 into the negative pressure housing 9. One of the two transfer units is located inside the negative pressure housing 9 to store the workpiece for grinding, and the other transfer unit is located outside the negative pressure housing 9 to take out the ground workpiece and put in the unground workpiece.

[0072] Furthermore, the bottom of the negative pressure housing 9 is also equipped with several cleaning nozzles for spraying cleaning fluid to flush the impurities scattered at the bottom of the negative pressure housing 9 into the water tank 34 for treatment.

[0073] A dust removal method, using the aforementioned integrated grinding workstation, includes the following steps:

[0074] The workpiece is placed on the workpiece storage tray 105, and the transfer push rod 103 drives the transfer frame 104 and the workpiece storage tray 105 to move, moving the workpiece storage tray 105 into the negative pressure housing 9.

[0075] The grinding robot 11 clamps the workpiece and moves it to the position of the grinding wheel 12. The grinding motor drives the grinding wheel 12 to rotate, and the grinding wheel 12 grinds the workpiece.

[0076] The fan 31 draws dust from the air inside the negative pressure housing 9 into the air duct, and the water curtain generator 33 sprays water into the air duct. The dust in the air is captured and flows into the separation tank 4.

[0077] Separator 4 is in processing mode, and impurities in the water are trapped.

[0078] After a period of time, the separator 4 switches to the cleaning mode, the sealing strip 51 is removed, the cleaning brush 52 extends to the inner wall of the separator 4, the liquid outlet pipe 7 is closed and the drain pipe 6 is opened, and the drive assembly 8 drives the separator 4 to rotate in the opposite direction to the cleaning brush 52, brushing off the impurities on the inner wall of the separator 4 and discharging them through the drain pipe 6.

[0079] Working principle of this invention:

[0080] The workpiece is placed on the workpiece storage tray 105. The transfer push rod 103 moves the transfer frame 104 and the workpiece storage tray 105, moving the workpiece storage tray 105 into the negative pressure housing 9. The grinding robot arm 11 clamps the workpiece and moves it to the position of the grinding wheel 12. The grinding motor drives the grinding wheel 12 to rotate, and the grinding wheel 12 grinds the workpiece. At the same time, the fan 31 sucks the dust in the air inside the negative pressure housing 9 into the exhaust duct. The water curtain generator 33 sprays water into the exhaust duct. The dust in the air is trapped and flows into the water tank 34. The water pump introduces the wastewater into the separation tank 4. Impurities in the water are trapped and the pump drives the separation tank 4. Motor 806 drives the drive pulley to rotate, which in turn drives the drive belt to rotate. The drive belt causes the driven pulley to rotate, which in turn drives the drive rod 801 to rotate. The drive rod 801 drives the separation drive gear 804 to rotate, which in turn drives the separation drive gear ring 807 to rotate. The separation drive gear ring 807 drives the separation tank 4 to rotate, causing the water and impurities in the separation tank 4 to be centrifuged, accelerating the discharge of water. The filtered water enters the treatment tank 1 and is discharged through the outlet pipe 7. When it is necessary to clean the separation tank 4, the outlet pipe 7 is closed, the drain pipe 6 is opened, and the back spray pipe 58 is connected to an external water source to allow water to flow into the back spray housing 57. The back spray shell 57 sprays cleaning water onto the outer wall of the separator 4. Simultaneously, the drive push rod 53 moves the connecting block 54, which in turn moves the sealing strip 51. The sealing strip 51 then moves the cleaning brush 52, causing it to move to the inner wall of the separator 4. The switching cylinder 812, via the compression spring 813, lowers the moving plate 811. The moving plate 811 lowers the rectangular drive cylinder 810, which descends on the rectangular drive block 809. The rectangular drive cylinder 810 drives the cleaning drive gear 802 to rotate, causing it to move downwards and mesh with the intermediate gear 803. The drive rod 801 then... The rectangular drive block 809 rotates, which drives the rectangular drive cylinder 810 to rotate. The rectangular drive cylinder 810 drives the cleaning drive gear 802 to rotate, which drives the cleaning drive gear ring 808 to rotate. The cleaning drive gear ring 808 drives the fixed block 55 and the connecting block 54 to rotate. The connecting block 54 drives the sealing strip 51 and the cleaning brush 52 to rotate. The cleaning brush 52 rotates in the opposite direction to the separation tank 4. The cleaning brush 52 rotates on the inner wall of the separation tank 4, brushing off the impurities on the inner wall of the separation tank 4. In conjunction with the back spray shell 57, cleaning water is sprayed into the separation tank 4 in the opposite direction to clean the separation tank 4. The impurities are discharged through the drain pipe 6.

[0081] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
