Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a water-rotating paint spraying room wastewater treatment device. Background Art

[0002] The hydrocyclone spray booth mainly separates the particulate matter in the wastewater and exhaust gas generated during the painting process by the rotation of water flow. This device is usually used in spray booths or painting workshops containing pollutants such as paint mist, paint, solvents, etc. Hydrocyclone technology uses the rotating water flow to generate centrifugal force to help effectively separate paint, oil, suspended matter and other pollutants.

[0003] The water-cyclone spray paint room wastewater treatment device is an efficient and environmentally friendly wastewater treatment system, which is suitable for wastewater treatment in the coating industry. Through this system, not only can the pollution to the environment be reduced, but also the recycling and resource utilization of wastewater can be realized. Wastewater treatment is one of the important links in the entire treatment system. During the painting process, the water cyclone can take away a large amount of particulate matter generated by the painting, and the subsequent water flow will enter the dedicated wastewater treatment device to complete the separation of paint residue, debris and water flow, so that the water flow can be recycled within a certain period of time. However, the existing water-cyclone spray paint room wastewater treatment devices on the market are usually designed with several continuous separation tanks. In the actual working process, the wastewater will be collected and enter the separation tank. However, due to the large water inlet and fast flow rate of the separation tank, the paint residue and debris will be continuously mixed and stirred in the water, so that the paint residue, debris and water flow cannot be quickly separated, which will affect the recycling of the water flow. At the same time, the paint residue and other debris separated in the separation tank generally need to be manually cleaned regularly, which is not only time-consuming and labor-intensive, but also inefficient, and will also waste a certain amount of manpower and material resources. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a water-cyclone type spray paint room wastewater treatment device.

[0005] The technical solution adopted to solve the above technical problems is: a water-rotating paint spray room wastewater treatment device, comprising a water flow buffer mechanism, a wastewater separation mechanism is provided below the water flow buffer mechanism, and a paint residue separation filter cloth is fixedly installed in the wastewater separation mechanism to separate and filter paint residues and debris in the wastewater;

[0006] A separation drive mechanism corresponding to the paint residue separation filter cloth is installed on one side of the rear end of the wastewater separation mechanism, and a spray separation mechanism is fixedly installed on the separation drive mechanism;

[0007] A paint residue collecting mechanism is provided at one end of the wastewater separation mechanism, and a flow guiding mechanism is connected to the bottom of the rear end of the wastewater separation mechanism;

[0008] The rear end of the flow guide mechanism is fixedly connected with a filtered water storage mechanism, and the center of the inner surface of the front end of the filtered water storage mechanism is slidably mounted with a secondary filtering mechanism.

[0009] Furthermore, the water flow buffering mechanism includes a buffer box, a water inlet is provided at one end of the buffer box, a plurality of buffer inclined plates are fixedly connected inside the buffer box, a guide cover is fixedly connected to one side of the bottom of the buffer box, a plurality of evenly distributed diverter plates are fixedly connected inside the guide cover, and a main support frame for support is fixedly connected to the outside of the buffer box.

[0010] Through the above technical scheme, the water flow buffer mechanism is mainly used for buffering treatment of recycled water flow. The recycled wastewater will enter the buffer box through a dedicated pipe via the water inlet. After entering the buffer box, the water flow will flow along multiple buffer inclined plates. Then the water flow will fall into the guide cover through the gaps between the multiple buffer inclined plates. Since the guide cover is fixedly connected with multiple laterally evenly distributed diverter plates, the falling water flow will be further divided by the multiple diverter plates, thereby achieving further dispersion of the water flow, thereby greatly reducing the impact force of the water flow entering the wastewater separation mechanism below, and further reducing the disturbance caused by the water flow entering the wastewater separation mechanism.

[0011] The inclination angles of the plurality of buffer inclined plates are the same, and the plurality of buffer inclined plates are distributed in a stepped ascending manner from the water inlet to the other end.

[0012] Through the above technical solution, the water flow entering the buffer box can climb along multiple buffer inclined plates, thereby quickly reducing the flow velocity and impact force of the water flow, thereby achieving a buffering effect. When the water flow velocity gradually decreases, it will automatically fall into the guide cover along the gaps between the multiple buffer inclined plates.

[0013] Furthermore, the wastewater separation mechanism includes a wastewater separation box located directly below the water flow buffer mechanism, a slag guide plate is provided at one end of the wastewater separation box, and a first guide hole is opened at the bottom of the rear end of the wastewater separation box.

[0014] Through the above technical scheme, the wastewater separation mechanism is used to separate paint residue and debris in the wastewater, and needs to be used in conjunction with the paint residue separation filter cloth during the working process. After the buffered wastewater enters the wastewater separation box, the paint residue separation filter cloth divides the wastewater separation box into two upper and lower areas, and the paint residue separation filter cloth is located in the middle, so that the paint residue and debris in the wastewater can be filtered. The water flows into the lower area after being filtered by the paint residue separation filter cloth, and then enters the diversion mechanism through the first diversion hole, and finally flows to the filtered water storage mechanism, and the intercepted paint residue and debris will be retained above the paint residue separation filter cloth; in addition, the front and rear end sides of the paint residue separation filter cloth are tightly fitted with the inner wall of the wastewater separation box, so as to better reduce the impurities in the upper water body from entering the lower water body, thereby achieving better interception and filtration effect.

[0015] Furthermore, the separation drive mechanism includes an elongated hole opened at the top of the front and rear ends of the wastewater separation box, a transverse guide rail is fixedly connected to the top of the rear end of the wastewater separation box, both sides of the rear end of the wastewater separation box are rotatably connected with a rotating shaft, the outer sides of the two rotating shafts are fixedly connected with pulleys, a transmission belt is installed between the two pulleys, one side of the rear end of the wastewater separation box is fixedly connected with a motor seat, a servo motor is installed on the motor seat, the output shaft of the servo motor is fixedly connected to the corresponding pulley, a first connecting seat is fixedly installed on the transmission belt, the front end of the first connecting seat is fixedly connected to a limiting slide, the limiting slide is slidably limited in the transverse guide rail, the front end of the limiting slide is fixedly connected with a fixing rod passing through the two elongated holes, and the front end of the fixing rod is fixedly connected to a limiting ring.

[0016] Through the above technical scheme, whenever the equipment has been operating normally for a certain period of time, the paint residue separation filter cloth will be driven by the separation drive mechanism to move, so that the intercepted paint residue and debris will be automatically driven into the paint residue collection mechanism. During specific operation, the corresponding pulley is driven by the servo motor to rotate, and the rotation of the pulley will drive the transmission belt to move, so that the transmission belt can be used to drive the first connecting seat, the limiting slide and the fixed rod to move synchronously. Since the fixed rod is located below the paint residue separation filter cloth, and the overall height of the fixed rod is higher than the liquid level in the wastewater separation box, when the fixed rod moves in the direction of the slag guide plate, the fixed rod can continuously lift the paint residue separation filter cloth at the corresponding position, and make the paint residue separation filter cloth present. The wave-like movement can drive the paint residue floating on the water surface and the impurities in the water in the upper area of ​​the paint residue separation filter cloth toward the slag guide plate until all the paint residue and impurities are automatically driven into the paint residue collection mechanism, thereby completing the automatic collection of the paint residue and impurities. In addition, since the overall water permeability of the paint residue separation filter cloth is good, during the driving process, a large amount of water will not flow out from the position of the slag guide plate. After the automatic driving and collection of the paint residue is completed, the servo motor will drive the fixed rod to automatically reset. In addition, the front and rear ends of the fixed rod are respectively fixedly connected to the limit ring and the limit slide, so that the fixed rod can play a better limiting role during the movement, thereby ensuring the stability of the fixed rod during the movement.

[0017] Furthermore, the spray separation mechanism includes a second connecting seat fixed on the first connecting seat, a spray pipe is fixedly connected to the front end of the second connecting seat, a plurality of evenly distributed spray holes are opened on the spray pipe, a connecting head is provided at the center of one side of the spray pipe, and a water supply pipe for water supply is connected to the connecting head.

[0018] Through the above technical scheme, when the separation driving mechanism drives the paint residue separation filter cloth to separate paint residue and impurities, some of the paint residue and impurities in the upper water body will easily adhere to the paint residue separation filter cloth. By setting up a spray separation mechanism, some of the impurities and paint residue attached to the paint residue separation filter cloth can be further automatically cleaned. During specific operation, the high-pressure water flow pumped in the water diversion pipe will enter the spray pipe through the connector. A plurality of evenly distributed spray holes are provided on the lower side of the spray pipe close to the direction of the slag guide plate. Therefore, when the spray holes move synchronously with the fixed rod, the scattered high-pressure water flow sprayed through the plurality of spray holes will automatically spray and clean some of the impurities and paint residue attached to the paint residue separation filter cloth. On the one hand, the impurities and paint residue attached to the paint residue separation filter cloth during the movement can be cleaned to the upper water body on one side. On the other hand, the sprayed high-pressure water flow can also perform high-pressure cleaning on the surface of the paint residue separation filter cloth, thereby ensuring the water permeability and filtering interception effect of the paint residue separation filter cloth in the subsequent continuous use, thereby ensuring the working efficiency of the paint residue separation filter cloth, and also extending its replacement cycle.

[0019] Furthermore, the paint residue collecting mechanism comprises a collecting box, a detachable separation frame is placed in the collecting box, and the front and rear ends of the top of the separation frame are fixedly connected with fixed handles.

[0020] Through the above technical scheme, the paint residue collection mechanism is mainly used to centrally collect the impurities and paint residues automatically cleaned out. The impurities and paint residues falling on the residue guide plate will be automatically collected in the separation frame. The bottom of the separation frame is a hollow filter structure, which can further realize the drainage function to ensure that solid impurities and paint residues can be collected in the separation frame, and a small amount of water will be collected at the bottom of the collection box, which can be processed separately manually later.

[0021] Furthermore, the flow guiding mechanism comprises a flow guiding pipe connected to the first flow guiding hole, and a valve is installed on the flow guiding pipe.

[0022] Through the above technical scheme, the diversion mechanism is mainly used to connect the wastewater separation mechanism and the filtered water storage mechanism. When working, the connectivity state of the diversion pipe can be controlled by the valve. When working, the separated water flow in the wastewater separation mechanism will enter the filtered water storage mechanism through the diversion pipe, and the water flow in the subsequent filtered water storage mechanism can be recycled.

[0023] Furthermore, the filtered water storage mechanism includes a filtered water storage box fixedly connected to the rear end of the guide pipe, a second guide hole communicating with the guide pipe is opened at the bottom of the front center of the filtered water storage box, and a filtered water return pipe and a drainage pipe are respectively fixedly connected to the bottom of the center of both ends of the filtered water storage box.

[0024] Through the above technical scheme, when the filtered water flows into the filtered water storage box, the water can be drawn out through the filtered water return pipe and pumped to the water cyclone mechanism for recycling. When the water body needs to be replaced as a whole, the drainage pipe can be opened so that the water in the filtered water storage box can be quickly discharged.

[0025] Furthermore, the secondary filtering mechanism includes a vertical slide rail fixed to the inner surface of the front end of the filtered water storage box, a filter cotton mounting seat is slidably installed in the vertical slide rail, a filter sponge is installed in the filter cotton mounting seat, and a lifting handle is fixedly connected to the top of the filter cotton mounting seat.

[0026] Through the above technical scheme, the secondary filtering mechanism is mainly used for secondary interception and filtration of water flow. Since the paint residue separation filter cloth cannot guarantee 100% interception during the filtration and separation process, a filter sponge can be installed at the second diversion hole at the front end of the filtered water storage box to achieve secondary interception and filtration of the water flow. Since the filter cotton mounting seat can be lifted and slid in the vertical slide rail through the lifting handle, the filter sponge can be replaced more conveniently and quickly, thereby ensuring the filtration efficiency of the water body.

[0027] The beneficial effects of the present invention are as follows: (1) The present invention can further buffer and disperse the water flow by designing a water flow buffer mechanism, thereby greatly reducing the impact force of the water flow entering the wastewater separation mechanism below, and further reducing the disturbance caused by the water flow entering the wastewater separation mechanism, thereby ensuring the subsequent interception and separation effect of paint residues and impurities; (2) The present invention designs a separation drive mechanism and a spray separation mechanism that cooperate with each other. During the movement, the fixed rod continuously lifts the paint residue separation filter cloth at the corresponding position and makes the paint residue separation filter cloth move in a wave-like manner, so that the paint residue floating on the water surface and the impurities in the water in the upper area of ​​the paint residue separation filter cloth can be driven toward the slag guide plate. In conjunction with the spray separation mechanism, all paint residues and impurities can be quickly and automatically driven into the paint residue collection mechanism, thereby completing the automatic collection of paint residues and impurities without manual intervention, and greatly improving work efficiency.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] like Figure 1-Figure 13 As shown, a water-cyclone paint spray room wastewater treatment device of the present embodiment includes a water flow buffer mechanism 1, the water flow buffer mechanism 1 includes a buffer box 101, one end of the buffer box 101 is provided with a water inlet 102, a plurality of buffer inclined plates 103 are fixedly connected in the buffer box 101, a guide cover 104 is fixedly connected to one side of the bottom of the buffer box 101, a plurality of evenly distributed diverter plates 105 are fixedly connected in the guide cover 104, a main support frame 106 for support is fixedly connected to the outside of the buffer box 101, and the water flow buffer mechanism 1 is mainly used for buffering treatment of recycled water flow, and the recycled wastewater will pass through A dedicated pipe enters the buffer box 101 through the water inlet 102. After entering the buffer box 101, the water flow will flow along the multiple buffer inclined plates 103, and then the water flow will fall into the guide cover 104 through the gaps between the multiple buffer inclined plates 103. Since the guide cover 104 is fixedly connected with multiple laterally evenly distributed diverter plates 105, the falling water flow will be further divided by the multiple diverter plates 105, thereby achieving further dispersion of the water flow, thereby greatly reducing the impact force of the water flow entering the wastewater separation mechanism 2 below, and further reducing the disturbance caused by the water flow entering the wastewater separation mechanism 2.

[0044] Furthermore, in this embodiment, the inclination angles of the multiple buffer inclined plates 103 are the same, and the multiple buffer inclined plates 103 are distributed in a stepped manner from the water inlet 102 to the other end, so that the water flow entering the buffer box 101 can climb along the multiple buffer inclined plates 103, thereby quickly reducing the flow velocity and impact force of the water flow, thereby achieving a buffering effect. When the water flow velocity gradually decreases, it will automatically fall into the guide cover 104 along the gaps between the multiple buffer inclined plates 103.

[0045] For wastewater separation mechanism 2, refer to Figure 6-Figure 7The wastewater separation mechanism 2 includes a wastewater separation box 201 located directly below the water flow buffer mechanism 1. A slag guide plate 202 is provided at one end of the wastewater separation box 201. A first guide hole 203 is provided at the bottom of the rear end of the wastewater separation box 201. The wastewater separation mechanism 2 is used to separate paint residue and debris in the wastewater. During the working process, it needs to be used in conjunction with the paint residue separation filter cloth 3. When the wastewater passing through the buffer enters the wastewater separation box 201, the paint residue separation filter cloth 3 divides the wastewater separation box 201 into two upper and lower areas. The paint residue separation filter cloth 3 is located at The paint residue and debris in the wastewater can be filtered out in the middle, and the water flows into the lower area after being filtered through the paint residue separation filter cloth 3, and then enters the diversion mechanism 7 through the first diversion hole 203, and finally flows to the filtered water storage mechanism 8, while the intercepted paint residue and debris will be retained above the paint residue separation filter cloth 3; in addition, the front and rear end sides of the paint residue separation filter cloth 3 are tightly fitted with the inner wall of the wastewater separation box 201, so as to better reduce the impurities in the upper water body from entering the lower water body, thereby achieving a better interception and filtration effect.

[0046] Regarding the paint residue separation filter cloth 3 and the separation drive mechanism 4, refer to Figure 10-13A paint residue separation filter cloth 3 is fixedly installed in the wastewater separation mechanism 2, which is used to separate and filter paint residues and debris in the wastewater; a separation drive mechanism 4 corresponding to the paint residue separation filter cloth 3 is installed on one side of the rear end of the wastewater separation mechanism 2, and the separation drive mechanism 4 includes a long hole 401 opened on the top of the front and rear ends of the wastewater separation box 201, and a transverse guide rail 402 is fixedly connected to the top of the rear end of the wastewater separation box 201. The two sides of the rear end of the wastewater separation box 201 are rotatably connected to a rotating shaft 403, and the outer sides of the two rotating shafts 403 are fixedly connected to pulleys 404. A transmission belt 405 is installed between the two pulleys 404, and a motor seat 406 is fixedly connected to one side of the rear end of the wastewater separation box 201. The motor A servo motor 407 is installed on the seat 406, and the output shaft of the servo motor 407 is fixedly connected to the corresponding pulley 404. A first connecting seat 408 is fixedly installed on the transmission belt 405. The front end of the first connecting seat 408 is fixedly connected to a limited position slide 409. The limited position slide 409 is slidably limited in the transverse guide rail 402. The front end of the limited position slide 409 is fixedly connected to a fixed rod 410 that passes through two long holes 401. The front end of the fixed rod 410 is fixedly connected to a limited position ring 411. Whenever the equipment operates normally for a certain period of time, the separation drive mechanism 4 will drive the paint residue separation filter cloth 3 to move, so that the intercepted paint residue and debris are automatically driven to the paint residue collection mechanism 6. During operation, the servo motor 407 drives the corresponding pulley 404 to rotate, and the rotation of the pulley 404 drives the transmission belt 405 to move, so that the transmission belt 405 can be used to drive the first connecting seat 408, the limiting slide 409 and the fixing rod 410 to move synchronously. Since the fixing rod 410 is located below the paint residue separation filter cloth 3, and the overall height of the fixing rod 410 is higher than the liquid level in the wastewater separation box 201, when the fixing rod 410 moves in the direction of the slag guide plate 202, the fixing rod 410 can continuously lift the paint residue separation filter cloth 3 at the corresponding position, and make the paint residue separation filter cloth 3 move in a wave-like manner, so that the paint residue floating on the water surface and the paint residue separation filter cloth 3 located at the paint residue separation filter cloth 3 can be lifted up. Impurities in the water in the upper area of ​​the cloth 3 are driven toward the slag guide plate 202 until all paint residues and impurities are automatically driven into the paint residue collecting mechanism 6, thereby completing the automatic collection of paint residues and impurities. Moreover, since the overall water permeability of the paint residue separation filter cloth 3 is good, during the driving process, a large amount of water will not flow out from the position of the slag guide plate 202. After the automatic driving and collection of the paint residue is completed, the servo motor 407 will drive the fixed rod 410 to automatically reset. In addition, the front and rear ends of the fixed rod 410 are respectively fixedly connected to the limit ring 411 and the limit slide 409, so that the fixed rod 410 can play a better limiting role during the movement, thereby ensuring the stability of the fixed rod 410 during the movement.

[0047] For spray separation mechanism 5, refer to Figure 10-13, a spray separation mechanism 5 is fixedly installed on the separation driving mechanism 4; the spray separation mechanism 5 includes a second connecting seat 501 fixed on the first connecting seat 408, a spray pipe 502 is fixedly connected to the front end of the second connecting seat 501, a plurality of evenly distributed spray holes 503 are opened on the spray pipe 502, a connecting head 504 is provided at the center of one side of the spray pipe 502, and a water diversion pipe 505 for water supply is connected to the connecting head 504. When the separation driving mechanism 4 drives the paint residue separation filter cloth 3 to separate the paint residue and impurities, some of the paint residue and impurities in the upper water body will be easily attached to the paint residue separation filter cloth 3. By setting the spray separation mechanism 5, some impurities and paint residues attached to the paint residue separation filter cloth 3 can be further automatically cleaned. When working, the high-pressure water flow pumped in the water diversion pipe 505 will pass through the connecting seat 501 to separate the paint residue and impurities. The joint 504 enters the spray pipe 502, and a plurality of evenly distributed spray holes 503 are opened on the lower side of the spray pipe 502 near the direction of the slag guide plate 202. Therefore, when the spray holes 503 move synchronously with the fixed rod 410, the scattered high-pressure water flow sprayed through the plurality of spray holes 503 will automatically spray and clean some impurities and paint residues attached to the paint residue separation filter cloth 3. On the one hand, the impurities and paint residues attached to the paint residue separation filter cloth 3 during the movement can be cleaned to the upper water body on one side. On the other hand, the sprayed high-pressure water flow can also perform high-pressure cleaning on the surface of the paint residue separation filter cloth 3, thereby ensuring the water permeability and filtering interception effect of the paint residue separation filter cloth 3 in the subsequent continuous use process, thereby ensuring the working efficiency of the paint residue separation filter cloth 3, and also extending its replacement cycle.

[0048] Regarding the paint residue collection mechanism 6, refer to Figure 7 A paint residue collecting mechanism 6 is provided at one end of the wastewater separation mechanism 2, and the paint residue collecting mechanism 6 includes a collecting box 601, in which a detachable separation frame 602 is placed, and the front and rear ends of the top of the separation frame 602 are fixedly connected with fixed handles 603. The paint residue collecting mechanism 6 is mainly used for centrally collecting impurities and paint residues automatically cleaned out, and the impurities and paint residues falling from the residue guide plate 202 will be automatically collected in the separation frame 602. The bottom of the separation frame 602 is a hollow filter mesh structure, which can further realize the drainage function to ensure that solid impurities and paint residues can be collected in the separation frame 602, and a small amount of water will be collected at the bottom of the collection box 601, which can be processed separately manually later.

[0049] Regarding the flow guide mechanism 7, refer to Figure 4-Figure 6The bottom of the rear end of the wastewater separation mechanism 2 is connected to a guide mechanism 7 that is connected thereto; the guide mechanism 7 includes a guide pipe 701 that is connected to the first guide hole 203, and a valve 702 is installed on the guide pipe 701. The guide mechanism 7 is mainly used to connect the wastewater separation mechanism 2 and the filtered water storage mechanism 8. When working, the connection state of the guide pipe 701 can be controlled by the valve 702. When working, the separated water flow in the wastewater separation mechanism 2 will enter the filtered water storage mechanism 8 through the guide pipe 701, and the water flow in the filtered water storage mechanism 8 can be recycled.

[0050] Regarding the filtered water storage mechanism 8, refer to Figure 1-Figure 8 The rear end of the guide mechanism 7 is fixedly connected to a filtered water storage mechanism 8, and the filtered water storage mechanism 8 includes a filtered water storage box 801 fixedly connected to the rear end of the guide pipe 701. A second guide hole 802 that is connected to the guide pipe 701 is opened at the bottom of the front end center of the filtered water storage box 801. The bottoms of the centers of both ends of the filtered water storage box 801 are respectively fixedly connected to a filtered water return pipe 803 and a drainage pipe 804. When the filtered water flows into the filtered water storage box 801, the water can be drawn out through the filtered water return pipe 803 and pumped to the water cyclone mechanism for recycling. When the water body needs to be replaced as a whole, the drainage pipe 804 can be opened so that the water in the filtered water storage box 801 can be quickly discharged.

[0051] Regarding the secondary filtering mechanism 9, refer to Figure 4-Figure 5 A secondary filtering mechanism 9 is slidably installed at the center of the inner surface of the front end of the filtered water storage mechanism 8. The secondary filtering mechanism 9 includes a vertical slide rail 901 fixed to the inner surface of the front end of the filtered water storage box 801. A filter cotton mounting seat 902 is slidably installed in the vertical slide rail 901. A filter sponge 903 is installed in the filter cotton mounting seat 902. A lifting handle 904 is fixedly connected to the top of the filter cotton mounting seat 902. The secondary filtering mechanism 9 is mainly used for secondary interception and filtration of water flow. Since the paint residue separation filter cloth 3 cannot guarantee 100% interception during the filtering and separation process, the filter sponge 903 can be installed at the second guide hole 802 at the front end of the filtered water storage box 801, thereby realizing secondary interception and filtration of the water flow. Since the filter cotton mounting seat 902 can be lifted and slid in the vertical slide rail 901 by the lifting handle 904, the filter sponge 903 can be replaced more conveniently and quickly, thereby ensuring the filtration efficiency of the water body.

[0052] The working principle of this embodiment is as follows: the recovered wastewater will enter the buffer tank 101 through the dedicated pipeline via the water inlet 102, and then the water will fall into the guide cover 104 through the gaps between the multiple buffer inclined plates 103, and the falling water will be further dispersed by the multiple diverter plates 105, and finally fall into the wastewater separation tank 201;

[0053] Since the paint residue separation filter cloth 3 divides the wastewater separation box 201 into two upper and lower areas, the paint residue separation filter cloth 3 is located in the middle, so that the paint residue and debris in the wastewater can be filtered. The water flows through the paint residue separation filter cloth 3 and enters the lower area, and then enters the diversion mechanism 7 through the first diversion hole 203, and finally flows to the filtered water storage mechanism 8. The center of the front inner surface of the filtered water storage mechanism 8 is slidably installed with a secondary filtering mechanism 9. The secondary filtering mechanism 9 is mainly used for secondary interception and filtration of the water flow. After the filtered water flows into the filtered water storage box 801, the water flow can be drawn out through the filtered water return pipe 803 and pumped to the water cyclone mechanism for recycling;

[0054] A separation driving mechanism 4 corresponding to the paint residue separation filter cloth 3 is installed on one side of the rear end of the wastewater separation mechanism 2, and a spray separation mechanism 5 is fixedly installed on the separation driving mechanism 4. During the movement of the fixed rod 410, the paint residue separation filter cloth 3 can be made to move in a wave-like manner, so that the paint residue floating on the water surface and the impurities in the water in the upper area of ​​the paint residue separation filter cloth 3 can be driven toward the slag guide plate 202. At the same time, by setting up the spray separation mechanism 5, some impurities and paint residues attached to the paint residue separation filter cloth 3 can be further automatically cleaned until all paint residues and impurities are automatically driven to the paint residue collection mechanism 6 for centralized collection.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
