[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The device realizes the pretreatment of the spray paint wastewater through the setting of the filtering unit. The funnel-shaped water inlet can guide the wastewater to quickly enter the filter chamber. The combination of the first filter, the second filter and the fence can intercept impurities of different particle sizes in turn, from large particles of paint residue to fine paint particles and suspended matter. This multiple filtering structure greatly improves the filtering accuracy, reduces the burden of the subsequent processing unit, and ensures the stable operation of the entire purification treatment device. The filter element is detachable, and the card slot on the assembly box facilitates the replacement of the first filter and the second filter. When the filter is blocked or damaged, there is no need to replace the entire filtering device. The filter can be disassembled and installed with simple operations, saving maintenance costs and time. At the same time, the setting of the liquid storage tank and the water pump can place flocculants in the liquid storage tank, and the flocculants are transported to the filter box through the water pump. The flocculants are fully mixed with the sewage, prompting the tiny particles, suspended matter and some oil pollution in the sewage to quickly condense into larger flocs, effectively improving the filtering efficiency, strengthening the interception ability of impurities in the sewage, and laying the foundation for subsequent treatment links; 2. In the sedimentation unit of the device, a sedimentation piece is provided in the sedimentation box. The sedimentation piece includes a connecting frame and multiple groups of inclined tubes. The inclined tubes are inclined and detachably connected to the connecting frame. The multiple groups of inclined tubes are provided to increase the sedimentation area. When the sewage flows through these inclined tubes, the water flow path is extended and the flow rate is slowed down. At this time, the sediment in the sewage, such as suspended paint particles, impurities, etc., can more fully contact the inner wall of the inclined tube, and then be adsorbed on the inner wall of the inclined tube, and quickly settle, thereby improving the sedimentation efficiency. An inclined buffer box is provided on one side of the sedimentation box. Multiple groups of buffer boxes are provided in the buffer box. The inner side surface of the bottom of the buffer box is provided with a wave, and a buffer sill is formed between adjacent buffer boxes. The water body treated by the filter unit flows into the sedimentation box from the high place of the buffer box to the low place. The setting of the buffer box can slow down the flow rate of the water flow. When the water body passes through the buffer sill, some impurities in the water body will be blocked by the buffer sill and stay on the buffer sill, further improving the interception effect of impurities. 3. The air dissolving tank and compressor of the separation unit of the device work together to dissolve air in water to form air-dissolving water, and the tiny bubbles are evenly released into the separation box through the distribution block on the distribution box. The bubbles adhere to impurities such as oil in the sewage and float up to achieve deep purification. The inverted triangle setting on the top of the distribution block and the air outlet holes on both sides ensure the uniform distribution of bubbles and improve the flotation efficiency. At the same time, the combination of the electric slider, the electric lifting rod and the collection box realizes the intelligent collection of floating impurities. The electric slider can move along the slide rail to drive the collection box to the specified position, and the electric lifting rod controls the lifting of the collection box to facilitate the collection of impurities. The collection net and the bottom trough design in the collection box facilitate the separation of impurities from water, and the inclined collection plate is conducive to the centralized collection of impurities. The setting of the waste box facilitates the storage and treatment of waste. The entire separation process is efficient and convenient, reducing manual operations and improving the automation of the purification treatment device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the scope of protection of the present invention.

[0017] Example: Figures 1 to 11 As shown, the present invention provides a paint spraying wastewater oil pollution purification treatment device, including a filtering unit, a sedimentation unit and a separation unit. The sedimentation unit includes a main frame 101 and a sedimentation box 102. A first mounting plate 103 is placed on the top of the main frame 101, and the mounting plate provides a stable support for the filter unit; and a second mounting plate 104 is arranged at the bottom of the main frame 101, which carries the separation unit. The sedimentation box 102 is fixed on the main frame 101, and a sedimentation bottom box 105 is connected below the sedimentation box 102. The sedimentation bottom box 105 and the sedimentation box 102 are connected together in a detachable manner to form a sedimentation chamber. A sedimentation piece is arranged in the sedimentation chamber, and the sedimentation piece is also detachably connected to the sedimentation bottom box 105. The entire sedimentation unit is mutually connected with the filtering unit and the separation unit respectively. When the paint spraying wastewater flows in, it will first enter from the water inlet 21 of the filtering unit, and the filtering unit will perform preliminary impurity interception and other treatments on the wastewater. After the preliminary treatment, the wastewater will flow into the sedimentation unit and complete the sedimentation process in the sedimentation chamber. The precipitated sewage then flows into the separation unit, and after further purification treatment, the purified water that meets the standards is finally discharged from the water outlet 22 of the separation unit. Through such a structural setting and the coordinated operation between the units, the device can effectively treat the spray paint sewage. At the same time, the entire device is controlled by an external controller, and the controller adopts a common and general controller.

[0018] like Figures 2 to 4 , Fig.11 As shown, the filter unit includes a filter box 301 and a filter cover plate 302. The filter cover plate 302 and the filter box 301 are detachably connected, and a filter chamber is formed after the two are connected. The filter box 301 is mounted on the first mounting plate 103, thereby achieving a stable placement in the device. The water inlet 21 is arranged on the top of the filter cover plate 302, and its top is funnel-shaped. Such a shape enables the paint spraying wastewater to flow more smoothly into the filter chamber. When the sewage enters the filter box 301, the filtering process begins. A mounting frame 303 is arranged in the filter box 301. The filter element in the filter chamber is located directly below the water inlet 21, and the filter element is clamped in the mounting frame 303. This arrangement ensures the stable position of the filter element in the filter box 301, which is conducive to the effective filtering of sewage. A plurality of first water outlet pipes are arranged on one side of the filter box 301, and solenoid valves are installed on the first water outlet pipes. These first water outlet pipes are located above the sedimentation unit. After the sewage is initially filtered in the filter cavity, the switch of the solenoid valve is controlled so that the initially filtered sewage can flow smoothly into the sedimentation unit.

[0019] The filter element includes an assembly box 304, a first filter screen 305, and a second filter screen 306. The assembly box 304 is hollowed out and has multiple sets of slots 307. The first filter screen 305 and the second filter screen 306 are respectively mounted in the slots 307 and are both detachably connected to the assembly box 304. The first filter screen 305 is located above the second filter screen 306, so that the sewage is first filtered by the first filter screen 305 and then further filtered by the second filter screen 306, which can effectively intercept impurities of different particle sizes. A fence 308 is also provided in the assembly box 304. The fence 308 is located above the first filter screen 305. It can initially block larger debris and prevent it from directly impacting the first filter screen 305. A liquid storage tank 309 and a water pump 310 are provided above the filter box 301. The liquid storage tank 309 is installed on the filter box 301, and the water pump 310 is installed on the filter cover plate 302. The water pump 310 is connected to the filter box 301 and the liquid storage tank 309 through connecting pipes. Flocculants can be placed in the liquid storage tank 309, and the water pump 310 transports the flocculants to the filter box 301 to fully mix the flocculants with the sewage, so as to make the tiny particles, suspended matter and some oil pollution in the sewage condense into larger floccules, further improve the filtering effect, and lay the foundation for subsequent sedimentation and separation treatment.

[0020] like Figure 2 , Figure 5 , Figure 8 , Fig. 9 As shown, a buffer box 106 is provided on one side of the sedimentation box 102, and the buffer box 106 is tilted. This tilted state helps the sewage to enter the sedimentation box 102 at a suitable flow rate and direction. A plurality of buffer boxes 107 are arranged above the buffer box 106. A through slot 108 is provided on one side of the buffer box 106. The buffer box 107 is inserted into the through slot 108 and is detachably connected to the buffer box 106, so as to facilitate the replacement or cleaning of the buffer box 107. A positioning block 109 is provided at the bottom of the buffer box 107, and a positioning slot 110 is provided at the position of the buffer box 106 corresponding to the positioning block 109. The positioning block 109 is clamped in the positioning slot 110 to ensure that the buffer box 107 can be stably installed on the buffer box 106. The edges of the two sides of the buffer box 107 are arranged in arcs. When multiple buffer boxes 107 contact each other, a buffer ridge is formed. Moreover, the inner side of the bottom of the buffer box 107 is in a wave shape, and when the sewage treated by the filter unit flows from the high position of the buffer box 106 to the low position into the sedimentation tank 102, the buffer box 106 can slow down the flow rate of the water flow. When the sewage flows through the buffer sill, some impurities in the water body will be blocked by the buffer sill and stay on the buffer sill, further intercepting the impurities in the sewage.

[0021] The sedimentation parts in the sedimentation box 102 are composed of a connecting frame 111 and multiple groups of inclined tubes 112. The inclined tubes 112 are hexagonal in shape and are arranged at an angle. Connecting clamps 113 are provided on both sides of the inclined tubes 112. The connecting clamps 113 are connected to the connecting frame 111 by connecting screws, so that the inclined tubes 112 and the connecting frame 111 are detachably connected. Multiple groups of inclined tubes 112 are equidistantly installed on the connecting frame 111 to form a honeycomb structure. This structure increases the sedimentation area. When sewage flows through these inclined tubes 112, the water flow path is extended and the flow rate is slowed down. At this time, the sediment in the sewage, such as suspended paint particles, impurities, etc., can more fully contact the inner wall of the inclined tube 112, and then adsorb on the inner wall of the inclined tube 112, quickly settle, and improve the sedimentation efficiency. The sedimentation bottom box 105 is located below the sedimentation box 102, and a plurality of second water outlet pipes are arranged on one side thereof. Solenoid valves are installed on the second water outlet pipes. By controlling the switch of the solenoid valves, the flow rate and speed of sewage flowing out of the sedimentation bottom box 105 can be adjusted. The second water outlet pipes are connected to the separation unit through water pipes, and the sewage after sedimentation treatment will flow into the separation unit through these second water outlet pipes for subsequent purification treatment.

[0022] like Figure 2 , Figure 6 , Figure 7 , Fig.10 As shown, the separation unit is an important part of the paint spraying wastewater oil purification treatment device, which is composed of a separation box 401, a dissolving tank 402 and a compressor 403. The separation box 401 is installed on the second mounting plate 104, and a water inlet pipe is provided on one side thereof, and the water inlet pipe is connected to the sedimentation unit through a water pipe, and the sewage after sedimentation treatment flows into the separation box 401 through this water inlet pipe. A fixed plate 404 is provided on one side of the separation box 401, and the fixed plate 404 is stepped. The dissolving tank 402 and the compressor 403 are both installed on the fixed plate 404, and the dissolving tank 402 is connected to the compressor 403 through a vent pipe. The compressor 403 provides compressed air for the dissolving tank 402, so that the air is dissolved in the water in the dissolving tank 402 to form dissolved air water. A distribution box 405 is also provided in the separation box 401, and the dissolving tank 402 is connected to the external water source and the distribution box 405 through a conduit, and the dissolved air water enters the separation box 401 after being distributed through the distribution box 405. A water outlet 22 is provided on one side of the separation box 401, through which the purified water after separation treatment is discharged.

[0023] There are multiple distribution blocks 406 on the top of the distribution box 405. The distribution blocks 406 are hollow and connected to the distribution box 405. The top of the distribution block 406 is in an inverted triangle shape, and multiple groups of equidistantly arranged air outlet holes 407 are opened on the inclined surfaces on both sides. When the dissolved air water enters the distribution box 405, tiny bubbles are released through these air outlet holes 407. These bubbles adhere to impurities such as oil in the sewage, causing the impurities to float up and achieve separation.

[0024] There are multiple groups of symmetrically distributed slide rails 408 on the top of the separation box 401, and a slidable electric slider 409 is provided on the slide rail 408. The connecting plate 410 above the separation box 401 is connected to the multiple groups of electric sliders 409 at both ends. There are multiple groups of electric lifting rods 419 and collection boxes 420 below the connecting plate 410, and one end of the electric lifting rod 419 is connected to the connecting plate 410, and the other end is connected to the collection box 420. Through the sliding of the electric slider 409 on the slide rail 408 and the lifting and lowering of the electric lifting rod 419, the collection box 420 can be moved to a suitable position for impurity collection. There are multiple hooks 411 on the inner side of the collection box 420, and the collection net 412 is mounted on these hooks 411. There are multiple groups of drain grooves 413 at the bottom of the collection box 420, and an inclined collection plate 414 is provided on one side. When the collecting box 420 collects the floating impurities, the water can flow back to the separation box 401 through the drain groove 413, and the impurities remain on the collecting net 412. The inclined collecting plate 414 can better concentrate the impurities.

[0025] A waste box 415 is detachably provided on one side of the separation box 401, and is located below the slide rail 408. A filter 416 and a collection box 417 are provided in the waste box 415, and the filter 416 is above the collection box 417, and the filter 416 and the waste box 415 are drawer-type structures, which are convenient for cleaning. A storage box 418 is also provided on one side of the separation box 401, which can be used to store some related tools or spare parts. The entire separation unit effectively realizes the separation and treatment of impurities such as oil pollution in sewage through the coordinated work of various components.

[0026] The specific usage and function of this embodiment are as follows: When in use, the paint spraying wastewater flows into the water inlet 21 of the filter unit, and the funnel-shaped water inlet 21 allows the wastewater to enter the filter chamber smoothly. The wastewater passes through the fence 308 in turn to initially block larger debris, and then passes through the first filter 305 and the second filter 306 to filter impurities of different particle sizes. In this process, the water pump 310 transports the flocculant in the liquid storage tank 309 to the filter box 301, mixes it with the wastewater, and causes tiny particles, suspended matter and some oil to condense into large flocs, thereby improving the filtering effect. The wastewater after preliminary filtration flows into the sedimentation unit by controlling the solenoid valve on the first outlet pipe on one side of the filter box 301.

[0027] The filtered sewage flows into the sedimentation tank 102, and first passes through the inclined buffer box 106. The buffer box 107 in the box slows down the flow rate of the water, and some impurities are intercepted by the buffer sill. Then the sewage enters the sedimentation chamber and flows through the honeycomb structure composed of the inclined tubes 112. The water flow path is extended, the flow rate is slowed down, and the sediment is adsorbed on the inner wall of the inclined tube 112 and settled. After the sedimentation is completed, the sewage is transported to the separation unit by controlling the solenoid valve on the second outlet pipe on one side of the sedimentation bottom box 105.

[0028] Turn on the power supply, start the compressor 403, so that it provides compressed air to the air dissolving tank 402, dissolving the air in the water to form air-dissolving water; at the same time, start the water pump 310 and put it in a standby state. The precipitated sewage flows into the separation box 401 through the water inlet pipe, and the air-dissolving water in the air dissolving tank 402 passes through the distribution block 406 on the top of the distribution box 405, and releases tiny bubbles from the air outlet 407. The bubbles adhere to impurities such as oil and dirt in the sewage and make them float. Start the electric slider 409 to move on the slide rail 408, drive the connecting plate 410 and the electric lifting rod 419 and the collection box 420 below to the appropriate position, and lower the collection box 420 to collect the floating impurities. The collection net 412 in the collection box 420 intercepts impurities, and the water flows back to the separation box 401 from the leakage groove 413. The inclined collection plate 414 concentrates the impurities. Clean the waste box 415 regularly, pull the drawer-type leakage net 416, and clean the intercepted impurities into the collection box 417. Finally, the purified water is discharged from the water outlet 22 on one side of the separation box 401 .
