Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and particularly relates to a water swirl type spray booth wastewater treatment device. Background Art

[0002] The water swirl type spray booth mainly separates particulate matter in wastewater and waste gas generated during the painting process through the rotational action of water flow. This device is usually used in spray booths or painting workshops containing pollutants such as paint mist, paint, and solvents. The water swirl flow technology utilizes the centrifugal force generated by the rotating water flow to effectively separate paint, oil stains, suspended matter, and other pollutants.

[0003] The water swirl type spray booth wastewater treatment device is an efficient and environmentally friendly wastewater treatment system applicable to wastewater treatment in the painting industry. Through this system, not only can environmental pollution be reduced, but also the recycling and resource utilization of wastewater can be achieved. Wastewater treatment is one of the important links in the entire treatment system. During the painting process, the water swirl flow can carry away a large amount of particulate matter generated by painting, and the subsequent water flow will enter a dedicated wastewater treatment device to complete the separation of paint sludge, debris, and water flow, so that the water flow can be recycled within a certain period of time. However, currently, the existing water swirl type spray booth wastewater treatment devices on the market usually only design several consecutive separation tanks. During the actual working process, the wastewater will be centrally collected and enter the separation tanks. However, due to the large inflow and fast flow rate of the separation tanks, the paint sludge and debris will continuously mix and stir in the water, resulting in the inability to quickly separate the paint sludge, debris, and water flow, thus affecting the recycling of the water flow. At the same time, the paint sludge and other debris separated in the current separation tanks generally need to be manually cleaned regularly, which is not only time-consuming and laborious, with low efficiency, but also wastes a certain amount of human and material resources. Summary of the Invention

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

[0005] The technical solution adopted to solve the above technical problem is: A water swirl type spray booth wastewater treatment device includes a water flow buffering mechanism. A wastewater separation mechanism is provided below the water flow buffering mechanism. A paint sludge separation filter cloth is fixedly installed in the wastewater separation mechanism for separating and filtering paint sludge and debris in the wastewater;

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

[0007] A paint sludge collection mechanism is provided at one end of the wastewater separation mechanism, and a guiding mechanism communicating with it is connected to the bottom at the rear end of the wastewater separation mechanism;

[0008] A water filtering and storing mechanism is fixedly connected to the rear end of the diversion mechanism, and a secondary filtering mechanism is slidably installed at the center of the inner surface of the front end of the water filtering and storing mechanism.

[0009] Furthermore, the water flow buffering mechanism includes a buffer box. One end of the buffer box is provided with a water inlet. A plurality of buffer inclined plates are fixedly connected inside the buffer box. One side of the bottom of the buffer box is fixedly connected with a diversion cover. A plurality of evenly distributed flow dividing plates are fixedly connected inside the diversion cover. A main support frame for support is fixedly connected to the outside of the buffer box.

[0010] Through the above technical solution, the water flow buffering mechanism is mainly used for buffering treatment of the recycled water flow. The recycled wastewater will enter the buffer box through a special pipeline via the water inlet. After the water flow enters the buffer box, it will flow along a plurality of buffer inclined plates. Subsequently, the water flow will fall into the diversion cover through the gaps between the plurality of buffer inclined plates. Since a plurality of horizontally evenly distributed flow dividing plates are fixedly connected inside the diversion cover, the falling water flow will be further divided by the plurality of flow dividing plates, thereby realizing further dispersion of the water flow, greatly reducing the impact force of the water flow entering the lower wastewater separation mechanism, and further reducing the disturbance caused after the water flow enters 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 manner rising from the water inlet to the other end.

[0012] Through the above technical solution, the water flow entering the buffer box can perform a climbing movement along the plurality of buffer inclined plates, thereby quickly reducing the flow rate and impact force of the water flow, and then realizing the buffering effect. When the water flow speed gradually decreases, it will automatically fall into the diversion cover through the gaps between the plurality of buffer inclined plates.

[0013] Furthermore, the wastewater separation mechanism includes a wastewater separation box located directly below the water flow buffering mechanism. One end of the wastewater separation box is provided with a slag guiding plate. A first diversion hole is opened at the bottom of the rear end of the wastewater separation box.

[0014] Through the above technical solution, the wastewater separation mechanism is used for separating paint residues and sundries in the wastewater. During the working process, it needs to cooperate with a paint residue separation filter cloth. When the buffered wastewater enters the wastewater separation box, since the paint residue separation filter cloth divides the wastewater separation box into upper and lower regions, and the paint residue separation filter cloth is located in the middle, the paint residues and sundries in the wastewater can be filtered. The water flow enters the lower region 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 water filtering and storing mechanism, while the intercepted paint residues and sundries will stay above the paint residue separation filter cloth; in addition, both the front and rear edges of the paint residue separation filter cloth are closely attached to the inner side wall of the wastewater separation box, so as to better reduce the entry of impurities in the upper water body into the lower water body, thereby realizing a better interception and filtering effect.

[0015] Further, the separation driving mechanism includes long holes opened at the top of the front and rear ends of the wastewater separation tank. A transverse guide rail is fixedly connected to the top of the rear end of the wastewater separation tank. Rotating shafts are rotatably connected to both sides of the rear end of the wastewater separation tank. Pulley wheels are fixedly connected to the outer sides of the two rotating shafts. A transmission belt is installed between the two pulley wheels. A motor seat is fixedly connected to one side of the rear end of the wastewater separation tank. A servo motor is installed on the motor seat. The output shaft of the servo motor is fixedly connected to the corresponding pulley wheel. A first connection seat is fixedly installed on the transmission belt. A limiting sliding seat is fixedly connected to the front end of the first connection seat. The limiting sliding seat is slidably limited within the transverse guide rail. A fixing rod passing through the two long holes is fixedly connected to the front end of the limiting sliding seat. A limiting ring is fixedly connected to the front end of the fixing rod.

[0016] Through the above technical solution, whenever the equipment operates normally for a certain period of time, the paint sludge separation filter cloth will be driven by the separation driving mechanism to move, so as to automatically drive the intercepted paint sludge and sundries into the paint sludge collection mechanism. Specifically, during operation, the servo motor drives the corresponding pulley wheel to rotate. When the pulley wheel rotates, it drives the transmission belt to move, so that the transmission belt can drive the first connection seat, the limiting sliding seat and the fixing rod to move synchronously. Since the fixing rod is located below the paint sludge separation filter cloth and the overall height of the fixing rod is higher than the liquid level in the wastewater separation tank, when the fixing rod moves towards the slag guiding plate, the fixing rod can continuously lift the corresponding position of the paint sludge separation filter cloth and make the paint sludge separation filter cloth move in a wavy shape, so as to drive the paint sludge floating on the water surface and the impurities in the water in the upper area of the paint sludge separation filter cloth towards the slag guiding plate until all the paint sludge and impurities are automatically driven into the paint sludge collection mechanism, thus completing the automatic collection of the paint sludge and impurities. And because the overall water permeability of the paint sludge separation filter cloth is good, a large amount of water will not gush out from the position of the slag guiding plate during the driving process. After the automatic driving and collection of the paint sludge are completed, the servo motor will drive the fixing rod to automatically reset. In addition, the limiting ring and the limiting sliding seat are respectively fixedly connected to the front and rear ends of the fixing rod, so that the fixing rod can play a better limiting role during the movement, thus ensuring the stability of the fixing rod during the movement.

[0017] Further, the spray separation mechanism includes a second connection seat fixed to the first connection seat. A spray pipe is fixedly connected to the front end of the second connection seat. A plurality of uniformly distributed spray holes are opened on the spray pipe. A connection head is provided at the center of one side of the spray pipe. A water inlet pipe for supplying water is connected to the connection head.

[0018] Through the above technical solution, when the separation drive mechanism drives the paint sludge separation filter cloth to separate paint sludge and impurities, some of the paint sludge and impurities in the upper water body are likely to adhere to the paint sludge separation filter cloth. By setting up a spray separation mechanism, it is possible to further automatically clean some of the impurities and paint sludge adhering to the paint sludge separation filter cloth. During specific operation, the high-pressure water flow pumped in the water inlet pipe will enter the spray pipe through the connector. A plurality of evenly distributed spray holes are opened on the lower side of the spray pipe close to the slag guide plate. Therefore, when the spray holes move synchronously with the fixed rod, the scattered high-pressure water flow ejected from the plurality of spray holes will automatically spray and clean some of the impurities and paint sludge adhering to the paint sludge separation filter cloth. On the one hand, the impurities and paint sludge adhering to the paint sludge separation filter cloth during the movement can be cleaned into the upper water body on one side. On the other hand, the ejected high-pressure water flow can also perform high-pressure cleaning on the surface of the paint sludge separation filter cloth, so as to ensure the water permeability and filtering and interception effect of the paint sludge separation filter cloth during subsequent continuous use, thereby ensuring the working efficiency of the paint sludge separation filter cloth and at the same time prolonging its replacement cycle.

[0019] Further, the paint sludge collection mechanism includes a collection box, and a separable separation frame is placed in the collection box. Fixed handles are fixedly connected to the front and rear ends of the top of the separation frame.

[0020] Through the above technical solution, the paint sludge collection mechanism is mainly used to centrally collect the automatically cleaned impurities and paint sludge. The impurities and paint sludge falling from the slag guide plate will be automatically collected in the separation frame. The bottom of the separation frame is a hollow filter screen structure, so as to further realize the water drainage function to ensure that solid impurities and paint sludge can be collected in the separation frame, while a small amount of water flow will be collected at the bottom of the collection box and can be processed separately by manual later.

[0021] Further, the diversion mechanism includes a diversion pipe communicated with the first diversion hole, and a valve is installed on the diversion pipe.

[0022] Through the above technical solution, the diversion mechanism is mainly used to connect the wastewater separation mechanism and the water filtration storage mechanism. During operation, the connection state of the diversion pipe can be controlled through the valve. During operation, the water flow separated in the wastewater separation mechanism will enter the water filtration storage mechanism through the diversion pipe, and the water flow in the subsequent water filtration storage mechanism can be recycled.

[0023] Further, the water filtration storage mechanism includes a water filtration storage box fixedly connected to the rear end of the diversion pipe. A second diversion hole communicating with the diversion pipe is opened at the bottom center of the front end of the water filtration storage box. Water filtration return pipes and drainage pipes are respectively fixedly connected to the bottom centers of both ends of the water filtration storage box.

[0024] Through the above technical solution, when the filtered water flow enters the water filtration storage tank, the water flow can be pumped out through the water filtration return pipe and pumped into the water swirl mechanism for recycling. When the water body needs to be replaced as a whole, the drain pipe can be opened so that the water in the water filtration storage tank can be quickly drained.

[0025] Further, the secondary filtration mechanism includes a vertical slide rail fixed to the inner surface of the front end of the water filtration storage tank. A filter cotton mounting seat is slidably installed in the vertical slide rail. A filter sponge is installed in the filter cotton mounting seat. The top of the filter cotton mounting seat is fixedly connected with a lifting handle.

[0026] Through the above technical solution, the secondary filtration mechanism is mainly used for the secondary interception and filtration of the 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 water filtration storage tank, thereby realizing the 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) By designing a water flow buffering mechanism, the present invention can further buffer and disperse the water flow, thereby greatly reducing the impact force of the water flow entering the lower waste water separation mechanism and further reducing the disturbance caused after the water flow enters the waste water separation mechanism, thereby ensuring the subsequent interception and separation effect of paint residues and impurities; (2) By designing a separation driving mechanism and a spray separation mechanism that cooperate with each other, the fixed rod continuously lifts the paint residue separation filter cloth at the corresponding position during the movement process and makes the paint residue separation filter cloth move in a wavy shape, so that the paint residues floating on the water surface and the impurities in the water in the upper layer area of the paint residue separation filter cloth can be driven towards the slag guiding plate. Cooperating 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 the work efficiency.

Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

[0043] As Figures 1 - 13 shown, a wastewater treatment device for a water swirl spray booth in this embodiment includes a water flow buffering mechanism 1. The water flow buffering mechanism 1 includes a buffer tank 101. One end of the buffer tank 101 is provided with a water inlet 102. A plurality of buffer inclined plates 103 are fixedly connected in the buffer tank 101. One side of the bottom of the buffer tank 101 is fixedly connected with a flow guide cover 104. A plurality of uniformly distributed flow dividing plates 105 are fixedly connected in the flow guide cover 104. The outside of the buffer tank 101 is fixedly connected with a main support frame 106 for support. The water flow buffering mechanism 1 is mainly used for the buffering treatment of the recycled water flow. The recycled wastewater will enter the buffer tank 101 through the water inlet 102 via a special pipeline. After the water flow enters the buffer tank 101, it will flow along the plurality of buffer inclined plates 103, and then the water flow will fall into the flow guide cover 104 through the gaps between the plurality of buffer inclined plates 103. Since a plurality of horizontally uniformly distributed flow dividing plates 105 are fixedly connected in the flow guide cover 104, the falling water flow will be further divided by the plurality of flow dividing plates 105, thereby further dispersing the water flow, greatly reducing the impact force of the water flow entering the lower wastewater separation mechanism 2, and further reducing the disturbance caused after the water flow enters the wastewater separation mechanism 2.

[0044] Furthermore, in this embodiment, the inclination angles of the plurality of buffer inclined plates 103 are the same, and the plurality of buffer inclined plates 103 are distributed in a stepped manner rising from the water inlet 102 to the other end, so that the water flow entering the buffer tank 101 can perform a climbing movement along the plurality of buffer inclined plates 103, thereby quickly reducing the flow rate and impact force of the water flow, and then realizing the buffering effect. When the water flow speed gradually decreases, it will automatically fall into the flow guide cover 104 through the gaps between the plurality of buffer inclined plates 103.

[0045] Regarding the wastewater separation mechanism 2, refer to Figures 6 - 7, the wastewater separation mechanism 2 includes a wastewater separation tank 201 located directly below the water flow buffering mechanism 1. A slag guide plate 202 is provided at one end of the wastewater separation tank 201, and a first diversion hole 203 is opened at the bottom of the rear end of the wastewater separation tank 201. The wastewater separation mechanism 2 is used for separating paint slag and sundries in the wastewater and needs to be used in cooperation with the paint slag separation filter cloth 3 during the working process. When the wastewater passing through the buffer enters the wastewater separation tank 201, since the paint slag separation filter cloth 3 divides the wastewater separation tank 201 into upper and lower regions and the paint slag separation filter cloth 3 is located in the middle, the paint slag and sundries in the wastewater can be filtered. The water flows through the paint slag separation filter cloth 3 and then enters the lower region, and then enters the diversion mechanism 7 through the first diversion hole 203 and finally flows to the water filtration and storage mechanism 8, while the intercepted paint slag and sundries will stay above the paint slag separation filter cloth 3. In addition, the front and rear edges of the paint slag separation filter cloth 3 are closely attached to the inner side walls of the wastewater separation tank 201, so that the entry of impurities in the upper layer of water into the lower layer of water can be better reduced, thus achieving a better interception and filtration effect.

[0046] Regarding the paint slag separation filter cloth 3 and the separation drive mechanism 4, refer to Figures 10 - 13, a paint sludge separation filter cloth 3 is fixedly installed inside the wastewater separation mechanism 2 for separating and filtering paint sludge and sundries in the wastewater; on one side of the rear end of the wastewater separation mechanism 2, a separation driving mechanism 4 corresponding to the paint sludge separation filter cloth 3 is installed. The separation driving mechanism 4 includes long strip holes 401 opened at the top of the front and rear ends of the wastewater separation box 201. A transverse guide rail 402 is fixedly connected to the top of the rear end of the wastewater separation box 201. Both sides of the rear end of the wastewater separation box 201 are rotatably connected with rotating shafts 403. Pulley wheels 404 are fixedly connected to the outer sides of the two rotating shafts 403. A transmission belt 405 is installed between the two pulley wheels 404. On one side of the rear end of the wastewater separation box 201, a motor base 406 is fixedly connected. A servo motor 407 is installed on the motor base 406. The output shaft of the servo motor 407 is fixedly connected to the corresponding pulley wheel 404. A first connection seat 408 is fixedly installed on the transmission belt 405. The front end of the first connection seat 408 is fixedly connected with a limit sliding seat 409. The limit sliding seat 409 is slidably limited inside the transverse guide rail 402. The front end of the limit sliding seat 409 is fixedly connected with a fixing rod 410 passing through the two long strip holes 401. The front end of the fixing rod 410 is fixedly connected with a limit ring 411. Whenever the equipment operates normally for a certain period of time, the paint sludge separation filter cloth 3 will be driven by the separation driving mechanism 4 to move, so as to automatically drive the intercepted paint sludge and sundries into the paint sludge collection mechanism 6. Specifically, during operation, the servo motor 407 drives the corresponding pulley wheel 404 to rotate. When the pulley wheel 404 rotates, it will drive the transmission belt 405 to move, so that the transmission belt 405 can drive the first connection seat 408, the limit sliding seat 409 and the fixing rod 410 to move synchronously. Since the fixing rod 410 is located below the paint sludge separation filter cloth 3 and the overall height of the fixing rod 410 is higher than the liquid level inside the wastewater separation box 201, when the fixing rod 410 moves towards the slag guiding plate 202, the fixing rod 410 can continuously lift the corresponding position of the paint sludge separation filter cloth 3 and make the paint sludge separation filter cloth 3 move in a wavy shape, so as to drive the paint sludge floating on the water surface and the impurities in the water in the upper layer area of the paint sludge separation filter cloth 3 towards the slag guiding plate 202 until all the paint sludge and impurities are automatically driven into the paint sludge collection mechanism 6, thus completing the automatic collection of the paint sludge and impurities. And because the overall water permeability of the paint sludge separation filter cloth 3 is good, during the driving process, a large amount of water will not gush out from the position of the slag guiding plate 202. After the automatic driving and collection of the paint sludge are completed, the servo motor 407 will drive the fixing rod 410 to automatically reset. In addition, the front and rear ends of the fixing rod 410 are respectively fixedly connected with a limit ring 411 and a limit sliding seat 409, so that the fixing rod 410 can play a better limiting role during the movement process, thus ensuring the smoothness of the fixing rod 410 during the movement process.

[0047] Regarding the spray separation mechanism 5, refer to Figures 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 guide mechanism 7, refer to Figures 4 - 6, at the bottom of the rear end of the wastewater separation mechanism 2, there is a diversion mechanism 7 connected thereto and communicating with it; the diversion mechanism 7 includes a diversion pipe 701 communicating with the first diversion hole 203, and a valve 702 is installed on the diversion pipe 701. The diversion mechanism 7 is mainly used to connect the wastewater separation mechanism 2 and the water filtration and storage mechanism 8. During operation, the communication state of the diversion pipe 701 can be controlled through the valve 702. During operation, the separated water flow in the wastewater separation mechanism 2 will enter the water filtration and storage mechanism 8 through the diversion pipe 701, and the water flow in the subsequent water filtration and storage mechanism 8 can be recycled.

[0050] Regarding the water filtration and storage mechanism 8, refer to Figures 1 - 8 , at the rear end of the diversion mechanism 7, there is a water filtration and storage mechanism 8 fixedly connected thereto. The water filtration and storage mechanism 8 includes a water filtration and storage tank 801 fixedly connected to the rear end of the diversion pipe 701. At the bottom of the center of the front end of the water filtration and storage tank 801, there is a second diversion hole 802 communicating with the diversion pipe 701. At the bottom of the centers of both ends of the water filtration and storage tank 801, there are fixedly connected a water filtration return pipe 803 and a drainage pipe 804 respectively. When the filtered water flow enters the water filtration and storage tank 801, the water flow can be pumped out through the water filtration return pipe 803 and pumped into the water swirl 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 water filtration and storage tank 801 can be quickly drained.

[0051] Regarding the secondary filtration mechanism 9, refer to Figures 4 - 5 , inside the front end inner surface center of the water filtration and storage mechanism 8, there is a secondary filtration mechanism 9 slidably installed. The secondary filtration mechanism 9 includes a vertical slide rail 901 fixed to the front end inner surface of the water filtration and storage tank 801. Inside the vertical slide rail 901, there is a filter cotton mounting seat 902 slidably installed. Inside the filter cotton mounting seat 902, there is a filter sponge 903 installed. At the top of the filter cotton mounting seat 902, there is a lifting handle 904 fixedly connected. The secondary filtration mechanism 9 is mainly used for the secondary interception and filtration of the water flow. Since the paint residue separation filter cloth 3 cannot guarantee 100% interception during the filtration and separation process, a filter sponge 903 can be installed at the second diversion hole 802 at the front end of the water filtration and storage tank 801, thereby realizing the secondary interception and filtration of the water flow. Since the filter cotton mounting seat 902 can be lifted and slid inside the vertical slide rail 901 through 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 recycled wastewater will enter the buffer tank 101 through the special pipeline via the water inlet 102. Subsequently, the water flow will fall into the diversion cover 104 through the gaps between the multiple buffer inclined plates 103. The falling water flow will be further dispersed by the multiple flow splitting plates 105 and finally fall into the wastewater separation tank 201;

[0053] Since the paint residue separation filter cloth 3 divides the wastewater separation tank 201 into upper and lower regions, and the paint residue separation filter cloth 3 is located in the middle, it can filter the paint residues and sundries in the wastewater. The water flows through the paint residue separation filter cloth 3 and enters the lower region, then enters the diversion mechanism 7 through the first diversion hole 203, and finally flows to the water filtration storage mechanism 8. A secondary filtration mechanism 9 is slidably installed at the center of the inner surface of the front end of the water filtration storage mechanism 8. The secondary filtration mechanism 9 is mainly used for the secondary interception and filtration of water flow. After the filtered water flow enters the water filtration storage tank 801, the water flow can be pumped out through the water filtration return pipe 803 and pumped into the water swirl mechanism for recycling;

[0054] On one side of the rear end of the wastewater separation mechanism 2, a separation driving mechanism 4 corresponding to the paint residue separation filter cloth 3 is installed. 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 move in a wavy shape, so that the paint residues floating on the water surface and the impurities in the water in the upper region of the paint residue separation filter cloth 3 can be driven towards the slag guide plate 202. At the same time, by setting the spray separation mechanism 5, some of the impurities and paint residues attached to the paint residue separation filter cloth 3 can be automatically cleaned until all the paint residues and impurities are automatically driven into the paint residue collection mechanism 6 for centralized collection.

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