Abstract

The application relates to the technical field of pollutant treatment, in particular to a pollutant treatment equipment which comprises a box body, a polishing mechanism, a water curtain forming mechanism, a first dust removal mechanism and a gas suction mechanism; the water curtain forming mechanism is used for forming a water curtain at the communication position of a first dust removal cavity and a polishing cavity. The first dust removal mechanism is used for removing dust in airflow. The gas suction mechanism is used for driving airflow to flow through an air inlet, the polishing cavity, the first dust removal cavity and an air outlet in sequence. In the process that the airflow flows from the polishing cavity to the first dust removal cavity, part of the dust settles in a first water storage cavity, and part of the dust falls into a second water storage cavity along the water curtain. After the airflow flows into the first dust removal cavity, the airflow ascends in the first dust removal cavity, and when the airflow flows through the first dust removal mechanism, the dust in the airflow is further removed by the first dust removal mechanism.

Description

Technical Field

[0001] This application relates to the field of pollutant treatment technology, and in particular to a pollutant treatment device. Background Technology

[0002] Grinding and polishing is a crucial process in the metal processing industry, generating a significant amount of dust. This dust, as a pollutant, not only contaminates the environment but also harms workers' health. Therefore, it is essential to effectively manage the dust generated during the grinding and polishing of metal parts.

[0003] Currently, existing pollutant treatment equipment includes a housing and a water curtain forming mechanism. Grinding work is performed inside the housing. The water curtain forming mechanism, installed inside the housing, creates a water curtain within the housing. Dust generated during grinding is carried by airflow through the water curtain and then discharged from the housing.

[0004] The existing technical solutions mentioned above have the following drawbacks: In practical applications, the existing pollutant treatment equipment has poor dust removal effect, and the exhaust airflow still carries dust. Summary of the Invention

[0005] To improve dust removal efficiency, this application provides a pollutant treatment device.

[0006] This application provides a pollutant treatment device, which adopts the following technical solution: A pollutant treatment device, comprising: The housing has a grinding chamber and a first dust removal chamber in the upper part, and a first water storage chamber and a second water storage chamber in the lower part. An air inlet connected to the grinding chamber is formed on one side, and an exhaust port connected to the first dust removal chamber is formed at the top of the other side. The bottom of the first dust removal chamber is connected to the bottom of the grinding chamber. The first water storage chamber is connected to the grinding chamber. The second water storage chamber is connected to the first dust removal chamber. The grinding mechanism, located inside the grinding chamber, is used to grind metal parts; A water curtain forming mechanism is installed inside the housing to form a water curtain at the connection between the first dust removal chamber and the grinding chamber. The first dust removal mechanism is installed inside the first dust removal chamber and is used to remove dust from the airflow; An air extraction mechanism is installed at the top of the first dust removal chamber to drive the airflow through the air inlet, grinding chamber, first dust removal chamber and air outlet in sequence.

[0007] By adopting the above technical solution, during the airflow from the grinding chamber to the first dust removal chamber, some dust settles in the first water storage chamber, while some dust falls into the second water storage chamber with the water curtain. After the airflow flows into the first dust removal chamber, it rises within the chamber and, upon passing through the first dust removal mechanism, is further cleaned of dust. This effectively improves the dust removal effect, resulting in a virtually dust-free exhaust airflow.

[0008] This application further specifies that the first dust removal mechanism includes: The lower drawer has an open structure at the bottom and top and is movably installed inside the first dust removal chamber; The dust filter plate is detachably installed in the lower drawer; The upper drawer has an open structure at the bottom and top, is movably installed in the first dust removal chamber, and is located above the lower drawer; The plate-type electrostatic precipitator is detachably installed in the upper drawer; The water-blocking component is installed inside the first dust removal chamber and located below the lower drawer.

[0009] By adopting the above technical solution, the dust removal filter plate in the lower drawer first removes larger dust particles from the airflow, and then the plate electrostatic precipitator in the upper drawer removes smaller dust particles from the airflow, effectively ensuring the dust removal effect. The water-blocking component can effectively remove water vapor in the rising airflow to ensure the stable operation of the plate electrostatic precipitator.

[0010] This application further specifies that the water-blocking component includes: There are multiple interceptor plates, all with an arc-shaped cross-section; at least one interceptor plate is fixed to one side of the inner wall of the first dust removal chamber; at least one interceptor plate is fixed to the other side of the inner wall of the first dust removal chamber; the interceptor plates on both sides are staggered in the vertical direction.

[0011] By adopting the above technical solution, when the airflow rises from the bottom of the first dust removal chamber, it moves upward in an "S" shaped path due to the action of the intercepting plates on both sides. During this process, water vapor in the airflow breaks away from the airflow trajectory due to inertia and adheres to the bottom surface of the intercepting plates, flowing down along the bottom surface of the intercepting plates into the second water storage chamber, effectively separating the water vapor mixed in with the airflow. During the airflow turning process, some of the unsettled dust impacts the bottom surface of the intercepting plates due to inertia and falls into the second water storage chamber with the water flow, playing a certain dust removal role and effectively reducing the workload of the dust removal filter plates and plate electrostatic precipitators. Since the cross-sections of multiple intercepting plates are all arc-shaped structures, the airflow can turn more smoothly, avoiding violent airflow impact, reducing the loss of extraction pressure, and ensuring dust removal efficiency.

[0012] This application further specifies that the water-blocking component also includes: The guide tube is fixedly connected to the inner wall of the first dust removal chamber on its outer wall, and has an open structure at its top. The top of the water-blocking cover is fixedly connected to the bottom of the guide tube, and its interior is connected to the interior of the guide tube. An air inlet hole is formed on the side wall. The lower water-blocking cover is fixedly connected at its top to the bottom of the upper water-blocking cover, and the bottom is an open structure. The interception net is fixed inside the first dust removal chamber, located below the lower water-blocking hood and above multiple interception plates; The absorbent pad is fixed to the top inside the guide tube.

[0013] By employing the above technical solution, as the airflow rises from the bottom of the first dust removal chamber, the staggered interceptor plates on both sides serve as initial water blocking and pre-dust removal. The interceptor net serves as a secondary interceptor of fine water droplets. The airflow flows from below the lower water-blocking hood into the upper water-blocking hood through the air inlet, and then rises along the guide tube. During this process, the airflow undergoes multiple turns, achieving deep water blocking. Finally, the absorbent pad removes the very small amount of water vapor remaining in the airflow.

[0014] This application further specifies that the water curtain forming mechanism includes: A water storage tank is installed on the outer wall of the first dust removal chamber near the grinding chamber. The submersible pump is installed in the second water storage chamber and is connected to the water storage tank through a diversion pipe. It is used to deliver water into the water storage tank. The guide plate has an arc-shaped cross-section and is installed on the outer wall of the first dust removal chamber near the grinding chamber. Its top end abuts against the bottom end of the water storage tank, and its bottom end extends to the connection between the first dust removal chamber and the grinding chamber. The first partition plate is inclined, with one side fixedly connected to the outer wall of the first dust removal chamber near the grinding chamber, and the other side fixedly connected to the side of the guide plate near the first dust removal chamber.

[0015] By adopting the above technical solution, the water storage tank acts as a buffer, preventing water flow fluctuations and ensuring the continuity and uniformity of the water curtain. No additional water source is required, enabling water reuse. Water from the second water storage chamber flows into the water storage tank through a drainage pipe, then flows downwards through a guide plate to form a water curtain below the guide plate. The raised surface of the guide plate guides the water flow to spread naturally, forming a complete and uniform water curtain at the connection between the first dust removal chamber and the grinding chamber. On one hand, the first partition plate improves the stability of the connection between the outer wall of the first dust removal chamber and the guide plate; on the other hand, the first partition plate prevents airflow from flowing onto the concave surface of the guide plate, allowing airflow to flow smoothly into the first dust removal chamber.

[0016] This application further specifies that: multiple diversion teeth are formed at the top of the opposite sides of the water storage tank; and multiple segmentation teeth are formed at the bottom of the guide plate.

[0017] By employing the above technical solution, the water flow is divided into multiple uniform fine streams by multiple diverting teeth, which helps to form a water curtain of uniform thickness. The water flowing down the guide plate is further divided by multiple diverting teeth into multiple fine streams, making the formed water curtain finer and more uniform. This significantly increases the contact area between the airflow and the water, improving the dust capture effect. At the same time, it avoids the formed water curtain from being too thick, reducing the resistance of the water flow to the airflow and ensuring the airflow rate.

[0018] This application further specifies that the polishing mechanism includes: A grating is installed at the top of the first water storage chamber; The control panel is set on the grating, and its top surface is used to support metal parts; Sandpaper storage assembly for storing sandpaper; A multi-axis robotic arm is used to pick up and put down sandpaper and to move the sandpaper on metal parts.

[0019] By adopting the above technical solutions, the grinding work can be replaced or assisted by manual labor, effectively reducing labor intensity and improving work efficiency.

[0020] This application further specifies that: a second dust removal chamber is formed in the upper part of the interior of the housing; the second dust removal chamber is located between the first dust removal chamber and the grinding chamber; Also includes: The second dust removal mechanism is installed in the second dust removal chamber and is connected to the grinding chamber and the first dust removal chamber respectively. It is used to remove dust from the airflow.

[0021] This application further specifies that the second dust removal mechanism includes: The second partition plate is installed in the lower part of the second dust removal chamber; through holes are formed on the second partition plate; The separator is fixedly connected at its bottom to the top of the second partition plate, and its interior is connected to the through hole. The air intake assembly is embedded inside one side wall of the second dust removal chamber and is connected to the bottom of the grinding chamber and the upper part of the separation cylinder, respectively. The air outlet assembly is embedded inside the other side wall of the second dust removal chamber and is connected to the top of the separator and the bottom of the first dust removal chamber, respectively.

[0022] By adopting the above technical solution, the airflow from the grinding chamber flows into the separator cylinder through the air inlet assembly and then flows to the bottom of the first dust removal chamber through the air outlet assembly. The separator cylinder separates larger dust particles from the airflow, causing the dust to fall in a spiral path into the first water storage chamber. This achieves the purpose of pre-dust removal, reduces the workload of the first dust removal mechanism, and improves the overall dust removal effect.

[0023] This application further includes: The back-blowing mechanism is installed at the top of the first dust removal chamber and is used to blow airflow into the first dust removal mechanism.

[0024] In summary, the beneficial technical effects of this application are as follows: 1. A water curtain forming mechanism is used to form a water curtain at the connection between the first dust removal chamber and the grinding chamber. The first dust removal mechanism is used to remove dust from the airflow. The exhaust mechanism is used to drive the airflow sequentially through the air inlet, the grinding chamber, the first dust removal chamber, and the air outlet. During the airflow from the grinding chamber to the first dust removal chamber, some dust settles in the first water storage chamber, and some dust falls into the second water storage chamber with the water curtain. After the airflow flows into the first dust removal chamber, it rises within the chamber and flows through the first dust removal mechanism, where the first dust removal mechanism further removes dust from the airflow. In this way, the dust removal effect is effectively improved, resulting in a virtually dust-free exhaust airflow.

[0025] 2. First, the dust collector filter in the lower drawer removes larger dust particles from the airflow, and then the plate electrostatic precipitator in the upper drawer removes smaller dust particles, effectively ensuring the dust removal effect. The water-blocking component can effectively remove water vapor from the rising airflow to ensure the stable operation of the plate electrostatic precipitator.

[0026] 3. As the airflow rises from the bottom of the first dust removal chamber, it moves upward in an "S" shaped path due to the action of the intercepting plates on both sides. During this process, water vapor in the airflow breaks away from the airflow trajectory due to inertia and adheres to the bottom surface of the intercepting plates, flowing down along the bottom surface into the second water storage chamber, effectively separating the water vapor mixed in with the airflow. During the airflow turning process, some of the unsettled dust impacts the bottom surface of the intercepting plates due to inertia and falls into the second water storage chamber with the water flow, playing a certain dust removal role and effectively reducing the workload of the dust removal filter plates and plate electrostatic precipitators. Because the cross-sections of multiple intercepting plates are all arc-shaped structures, the airflow can turn more smoothly, avoiding violent airflow impact, reducing the loss of extraction pressure, and ensuring dust removal efficiency.

[0027] 4. As the airflow rises from the bottom of the first dust removal chamber, the staggered interceptor plates on both sides serve as initial water blocking and pre-dust removal. The interceptor net further intercepts fine water droplets. The airflow flows from below the lower water-blocking hood into the upper water-blocking hood through the air inlet, and then rises along the guide tube. During this process, the airflow undergoes multiple turns, achieving deep water blocking. Finally, the absorbent pad removes the very small amount of water vapor remaining in the airflow.

[0028] 5. Multiple flow-dividing teeth separate the water flow into multiple uniform fine streams, which helps to form a water curtain of uniform thickness. The water flowing down the guide plate is further divided by multiple dividing teeth into multiple fine streams, making the formed water curtain finer and more uniform. This significantly increases the contact area between the airflow and the water, improving the dust capture effect. At the same time, it avoids the formed water curtain from being too thick, reducing the resistance of the water flow to the airflow and ensuring the airflow rate. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] Reference Figure 1 and Figure 2This application discloses a pollutant treatment device, including a housing 110, a grinding mechanism 120, a water curtain forming mechanism 130, a first dust removal mechanism 140, and an air extraction mechanism 150. A grinding chamber 111 and a first dust removal chamber 112 are formed in the upper part of the housing 110. The bottom of the first dust removal chamber 112 is connected to the bottom of the grinding chamber 111. A first water storage chamber 113 and a second water storage chamber 114 are formed in the lower part of the housing 110. The first water storage chamber 113 and the second water storage chamber 114 are separated from each other. The first water storage chamber 113 is connected to the grinding chamber 111, while the second water storage chamber 114 is connected to the first dust removal chamber 112. Water is stored in both the first water storage chamber 113 and the second water storage chamber 114. An air inlet connected to the grinding chamber 111 is formed on one side of the housing 110, and an exhaust port 115 connected to the first dust removal chamber 112 is formed at the top of the other side. An air inlet allows air to flow into the grinding chamber 111. An exhaust port 115 allows airflow to exit the first dust removal chamber 112. A grinding mechanism 120 is located inside the grinding chamber 111 and is used for grinding metal parts. A water curtain forming mechanism 130 is installed inside the housing 110 and is used to form a water curtain at the connection between the first dust removal chamber 112 and the grinding chamber 111. A first dust removal mechanism 140 is located inside the first dust removal chamber 112 and is used to remove dust from the airflow. An air extraction mechanism 150 is installed at the top inside the first dust removal chamber 112 and is used to drive the airflow sequentially through the air inlet, the grinding chamber 111, the first dust removal chamber 112, and the air outlet. During the airflow from the grinding chamber 111 to the first dust removal chamber 112, some dust settles in the first water storage chamber 113, and some dust falls with the water curtain into the second water storage chamber 114. After the airflow flows into the first dust removal chamber 112, it rises within the chamber and flows through the first dust removal mechanism 140, where the dust in the airflow is further removed. This effectively improves the dust removal effect, resulting in a virtually dust-free exhaust airflow.

[0033] Reference Figure 2In one embodiment, the first dust removal mechanism 140 includes a lower drawer 141, a dust removal filter plate 142, an upper drawer 143, and a plate electrostatic precipitator 144. The lower drawer 141 has open ends and is movably disposed within the first dust removal chamber 112. This facilitates the opening and closing of the lower drawer 141, thereby facilitating the replacement of the dust removal filter plate 142. The dust removal filter plate 142 is detachably installed within the lower drawer 141 for easy removal, replacement, and installation. The upper drawer 143 has open ends and is movably disposed within the first dust removal chamber 112, located above the lower drawer 141. This facilitates the opening and closing of the upper drawer 143, thereby facilitating the replacement of the plate electrostatic precipitator 144. The plate electrostatic precipitator 144 is detachably installed within the upper drawer 143 for easy removal, replacement, and installation. For the rising airflow within the first dust removal chamber 112, larger dust particles are first removed by the dust removal filter plate 142 in the lower drawer 141, and then smaller dust particles are removed by the plate electrostatic precipitator 144 in the upper drawer 143, effectively ensuring the dust removal effect. It should be noted that the plate electrostatic precipitator 144 charges the dust particles in the airflow using a high-voltage electric field and uses the electric field force to adsorb them onto the dust collection plate, thereby achieving the dust removal purpose. Therefore, the first dust removal mechanism 140 also includes a water-blocking component 145. The water-blocking component 145 is installed in the first dust removal chamber 112 and located below the lower drawer 141, effectively removing moisture from the rising airflow to ensure the stable operation of the plate electrostatic precipitator 144.

[0034] Preferably, there are two lower drawers 141, two dust collector filter plates 142, two upper drawers 143, and two plate electrostatic precipitators 144. The two lower drawers 141 are arranged side-by-side. The two dust collector filter plates 142 are installed in the lower drawers 141 in a one-to-one correspondence with each of the two lower drawers 141. The two upper drawers 143 are arranged side-by-side. The two plate electrostatic precipitators 144 are installed in the upper drawers 143 in a one-to-one correspondence with each of the two upper drawers 143.

[0035] In one embodiment, the water-blocking assembly 145 includes multiple intercepting plates 1451. The cross-sections of the multiple intercepting plates 1451 are all arc-shaped. At least one side of the intercepting plate 1451 is fixed to one inner wall of the first dust removal chamber 112, and at least one side of the intercepting plate 1451 is fixed to the other inner wall of the first dust removal chamber 112. The intercepting plates 1451 on both sides are staggered vertically. When the airflow rises from the bottom of the first dust removal chamber 112, it moves upward in an "S" shaped path due to the action of the intercepting plates 1451 on both sides. During this process, water vapor in the airflow is deflected from the airflow trajectory due to inertia and adheres to the bottom surface of the intercepting plate 1451, flowing down along the bottom surface of the intercepting plate 1451 into the second water storage chamber 114, effectively separating the water vapor mixed in with the airflow. During the airflow turning process, some of the unsettled dust particles impact the bottom surface of the interceptor plate 1451 due to inertia and fall into the second water storage chamber 114 with the water flow, achieving a certain dust removal effect and effectively reducing the workload of the dust removal filter plate 142 and the plate electrostatic precipitator 144. Since the cross-sections of multiple interceptor plates 1451 are all arc-shaped, the airflow can turn more smoothly, avoiding violent airflow impact, reducing the loss of extraction pressure, and ensuring dust removal efficiency.

[0036] Reference Figure 3 In another embodiment, the water-blocking assembly 145 includes multiple intercepting plates 1451, a guide tube 1452, an upper water-blocking cover 1453, a lower water-blocking cover 1454, an intercepting net 1455, and a water-absorbing pad 1456. The cross-sections of the multiple intercepting plates 1451 are all arc-shaped. At least one side of the intercepting plate 1451 is fixed to one inner wall of the first dust removal chamber 112, and at least one side of the intercepting plate 1451 is fixed to the other inner wall of the first dust removal chamber 112. The intercepting plates 1451 located on both sides are staggered in the vertical direction. The outer wall of the guide tube 1452 is fixedly connected to the inner wall of the first dust removal chamber 112, and its top end is an open structure. The top end of the upper water-blocking cover 1453 is fixedly connected to the bottom end of the guide tube 1452, and its interior is connected to the interior of the guide tube 1452. An air inlet 14531 is formed on its side wall. The top of the lower water-blocking cover 1454 is fixedly connected to the bottom of the upper water-blocking cover 1453. The bottom is an open structure, and its interior is not directly connected to the interior of the upper water-blocking cover 1453. The intercepting net 1455 is fixed inside the first dust removal chamber 112, located below the lower water-blocking cover 1454 and above the multiple intercepting plates 1451. The water-absorbing pad 1456 is fixed to the top inside the guide tube 1452. Figure 3The direction of the airflow is indicated by the middle arrow. As the airflow rises from the bottom of the first dust removal chamber 112, the staggered interceptor plates 1451 on both sides serve as initial water blocking and pre-dust removal. The interceptor net 1455 serves as a secondary interceptor of fine water droplets. The airflow flows from below the lower water blocking cover 1454 into the upper water blocking cover 1453 through the air inlet 14531, and then rises along the guide tube 1452. During this process, the airflow undergoes multiple turns, achieving deep water blocking. Finally, the water absorption pad 1456 removes the very small amount of water vapor remaining in the airflow.

[0037] Reference Figure 2 and Figure 4 In one embodiment, the water curtain forming mechanism 130 includes a water storage tank 131, a submersible pump 132, a guide plate 133, and a first partition plate 134. The water storage tank 131 is installed on the outer wall of the first dust removal chamber 112 near the grinding chamber 111, serving to buffer water, prevent water flow fluctuations, and ensure the continuity and uniformity of the water curtain. The submersible pump 132 is installed in the second water storage chamber 114 and communicates with the water storage tank 131 through a drainage pipe, used to supply water to the water storage tank 131. No additional water source is required, enabling water reuse. The guide plate 133 has an arc-shaped cross-section and is installed on the outer wall of the first dust removal chamber 112 near the grinding chamber 111. Its top end abuts against the bottom end of the water storage tank 131, and its bottom end extends to the connection point between the first dust removal chamber 112 and the grinding chamber 111. Water from the second water storage chamber 114 flows into the water storage tank 131 through the diversion pipe, and then flows downward through the guide plate 133 to form a water curtain below the guide plate 133. The convex surface of the guide plate 133 guides the water flow to spread naturally, forming a complete and uniform water curtain at the connection between the first dust removal chamber 112 and the grinding chamber 111. The first partition plate 134 is inclined, with one side fixedly connected to the outer wall of the first dust removal chamber 112 near the grinding chamber 111, and the other side fixedly connected to the side of the guide plate 133 near the first dust removal chamber 112. On the one hand, the first partition plate 134 improves the stability of the connection between the outer wall of the first dust removal chamber 112 and the guide plate 133; on the other hand, the first partition plate 134 can prevent the airflow from flowing to the concave surface of the guide plate 133, so that the airflow can flow smoothly into the first dust removal chamber 112.

[0038] Preferably, multiple diverting teeth 1311 are formed at the top of opposite sides of the water storage tank 131. These teeth divide the water flow into multiple uniform fine streams, facilitating the formation of a water curtain of uniform thickness. Multiple dividing teeth 1331 are formed at the bottom of the guide plate 133. The water flowing down the guide plate 133 is further divided by these teeth, becoming multiple fine streams, resulting in a finer and more uniform water curtain. This significantly increases the contact area between the airflow and the water, improving dust capture efficiency. Simultaneously, it prevents the water curtain from becoming too thick, reducing water resistance to airflow and ensuring the airflow rate.

[0039] Reference Figure 2 and Figure 5 In one embodiment, the polishing mechanism 120 includes a grid 121, an operating table 122, a sandpaper storage assembly 123, and a multi-axis robotic arm 124. The grid 121 is mounted on the top of the first water storage chamber 113. The operating table 122 is disposed on the grid 121, and its top surface is used to support metal parts. The sandpaper storage assembly 123 is used to store sandpaper. A suction cup is provided at the end of the multi-axis robotic arm 124. The multi-axis robotic arm 124 is used to pick up and put down sandpaper and to move the sandpaper across the metal parts to polish them. Overall, it can replace or assist manual polishing work, effectively reducing labor intensity and improving work efficiency.

[0040] Reference Figure 5In one embodiment, the sandpaper storage assembly 123 includes a support platform 1231, a lifting plate 1232, a linear actuator 1233, a guide rod 1234, four limit rods 1235, four peeling discs 1236, and a collection box 1237. The lifting plate 1232 is movably mounted above the support platform 1231, with its top surface used to support a stack of sandpaper. The linear actuator 1233 is mounted on the top of the support platform 1231, with its axis vertically aligned. Its output shaft is fixedly connected to the middle of the lifting plate 1232, driving the lifting plate 1232 to move up and down, thereby moving the stack of sandpaper up and down. The vertical height of the lifting plate 1232 can be adjusted according to the thickness of the sandpaper stack to facilitate the multi-axis robotic arm 124 in picking up the sandpaper. The guide rod 1234 is vertically aligned, with its bottom end fixed to the top of the support platform 1231. A guide hole is formed on the lifting plate 1232 for the guide rod 1234 to pass through. The guide rod 1234, in conjunction with the guide hole, improves the accuracy of the movement of the lifting plate 1232. Four limit rods 1235 are vertically positioned at the four corners of the lifting plate 1232, with their bottom ends fixedly connected to the top surface of the support platform 1231 to prevent the sandpaper stack from tilting or collapsing during lifting. Four peeling plates 1236 are fixed to the top of the limit rods 1235, corresponding one-to-one. When the multi-axis robotic arm 124 picks up the top layer of sandpaper, the four peeling plates 1236 prevent the next-to-top layer of sandpaper from moving upwards. The recycling box 1237 is fixed to the support platform 1231 and is used to recycle waste sandpaper. A recycling hole 12371 is provided at the top of the recycling box 1237. When the multi-axis robotic arm 124 moves the waste sandpaper across the top surface of the recycling box 1237, the recycling hole 12371 allows the sandpaper to detach from the multi-axis robotic arm 124.

[0041] Reference Figure 6 In one embodiment, a second dust removal chamber 116 is formed in the upper part of the interior of the housing 110. The second dust removal chamber 116 is located between the first dust removal chamber 112 and the grinding chamber 111. The pollutant treatment equipment also includes a second dust removal mechanism 160. The second dust removal mechanism 160 is installed in the second dust removal chamber 116 and is connected to the grinding chamber 111 and the first dust removal chamber 112 respectively, for removing dust in the airflow and guiding the dust to fall into the first water storage chamber 113.

[0042] Reference Figure 6 and Figure 7In one embodiment, the second dust removal mechanism 160 includes a second partition plate 161, a separation cylinder 162, an air inlet assembly 163, and an air outlet assembly 164. The second partition plate 161 is installed in the lower part of the second dust removal chamber 116, serving both to separate the second dust removal chamber 116 from the first water storage chamber 113 and to support the separation cylinder 162. A through hole is formed in the second partition plate 161. The bottom end of the separation cylinder 162 is fixedly connected to the top end of the second partition plate 161, and its interior communicates with the first water storage chamber 113 through the through hole. The air inlet assembly 163 is embedded inside one side wall of the second dust removal chamber 116, communicating with the bottom of the grinding chamber 111 and the upper part of the interior of the separation cylinder 162. The air outlet assembly 164 is embedded inside the other side wall of the second dust removal chamber 116, communicating with the top of the interior of the separation cylinder 162 and the bottom of the first dust removal chamber 112. Airflow from the grinding chamber 111 flows into the separator 162 via the air inlet assembly 163 and then flows to the bottom of the first dust removal chamber 112 via the air outlet assembly 164. The separator 162 separates larger dust particles from the airflow, causing them to fall in a spiral path into the first water storage chamber 113. This achieves pre-dust removal while reducing the workload of the first dust removal mechanism 140, thus improving the overall dust removal effect.

[0043] Preferably, the air intake assembly 163 includes a collecting hood 1631 and an air intake pipe 1632. The collecting hood 1631 is embedded in the lower part of the second dust removal chamber 116 near the grinding chamber 111. The air intake pipe 1632 is embedded in the side wall of the second dust removal chamber 116 near the grinding chamber 111, and communicates with the upper part of the interior of the collecting hood 1631 and the separating cylinder 162, respectively. The air outlet assembly 164 includes a diffuser hood 1641 and an air outlet pipe 1642. The diffuser hood 1641 is embedded in the lower part of the second dust removal chamber 116 near the first dust removal chamber 112. The air outlet pipe 1642 is embedded in the side wall of the second dust removal chamber 116 near the first dust removal chamber 112, and communicates with the top of the interior of the diffuser hood 1641 and the separating cylinder 162, respectively.

[0044] Reference Figure 2 and Figure 8In one embodiment, the pollutant treatment equipment further includes a backflushing mechanism 170. The backflushing mechanism 170 is installed at the top of the first dust removal chamber 112 and is used to blow airflow into the first dust removal mechanism 140. The backflushing mechanism 170 includes an air reservoir 171, two electromagnetic pulse valves 172, and two air blowing pipes 173. The air reservoir 171 stores compressed gas. The two air blowing pipes 173 are arranged side-by-side above the first dust removal mechanism 140. Each air blowing pipe 173 is connected to the air reservoir 171 through an electromagnetic pulse valve 172. By controlling the release of compressed gas through the electromagnetic pulse valves 172, pulsed backflushing is achieved. Compared with continuous blowing, this significantly reduces the consumption of compressed gas and lowers the operating cost of the equipment. Each air blowing pipe 173 has multiple nozzles 1731 evenly distributed axially at its bottom end to ensure that compressed gas is evenly blown onto all parts of the first dust removal mechanism 140.

[0045] The implementation principle of this embodiment is as follows: The water curtain forming mechanism 130 is used to form a water curtain at the connection between the first dust removal chamber 112 and the grinding chamber 111. The first dust removal mechanism 140 is used to remove dust from the airflow. The suction mechanism 150 is used to drive the airflow sequentially through the air inlet, the grinding chamber 111, the first dust removal chamber 112, and the air outlet. During the process of the airflow flowing from the grinding chamber 111 to the first dust removal chamber 112, part of the dust settles in the first water storage chamber 113, and part of the dust falls into the second water storage chamber 114 with the water curtain. After the airflow flows into the first dust removal chamber 112, it rises in the first dust removal chamber 112 and flows through the first dust removal mechanism 140, where the first dust removal mechanism 140 further removes the dust from the airflow. In this way, the dust removal effect is effectively improved, so that the discharged airflow is basically free of dust.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
