[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3A tire pyrolysis wastewater pretreatment device in this embodiment includes an operating table 1, on the surface of the operating table 1 are installed two filter cartridges 2, a stirring box 5 and a water collecting box 12, the two filter cartridges 2 are connected to the stirring box 5 through a water guide pipe 4, a water inlet pipe 3 is installed on the top of the outer side of the filter cartridge 2, the top of the stirring box 5 is connected to a drug inlet pipe 6 connected to an external doser, a filter frame 14 is installed on the top of the water collecting box 12, a sewage pipe 7 located above the filter frame 14 is installed at the bottom of the stirring box 5, the bottom of the stirring box 5 is inclined toward the sewage pipe 7, and an overflow pipe 16 is connected to the back of the water collecting box 12.

[0019] In the above structure, the wastewater is guided to the two filter cartridges through the water inlet pipe. The two filter cartridges can improve the filtration efficiency. At the same time, with the cooperation of the mixing box and the drug inlet pipe, the wastewater and the drug can be fully mixed to improve the quality and efficiency of water treatment. After stirring evenly, the sewage is discharged through the sewage pipe. At this time, the filter frame will filter the wastewater again, and then allow the wastewater to settle in the water collecting tank until it is discharged through the overflow pipe.

[0020] There are two water collecting tanks 12, which are connected by an overflow pipe 16, which is a three-way pipe. The support portion of the mixing tank 5 is located below the sewage pipe 7 and is fixed with a U-shaped flow channel 9. The two ends of the U-shaped flow channel 9 are respectively located above the filter frames 14 on the two water collecting tanks 12. When the sewage pipe discharges sewage, the U-shaped flow channel can guide the wastewater to the two filter frames for filtration, collection and sedimentation, thereby improving the efficiency of water source treatment.

[0021] In addition, Figure 2 A support seat 8 is fixed at the supporting part of the mixing box 5, and a long hole is opened on the support seat 8. The U-shaped flow channel 9 is slidably connected to the top of the support seat 8. A baffle 10 is formed on the inner side of one end of the U-shaped flow channel 9 close to the sewage pipe 7. The baffle 10 is convex in shape. A cylinder 11 is hinged at the bottom of the support seat 8, and the ejection end of the cylinder 11 is hinged to the bottom of the U-shaped flow channel 9. When sewage is discharged through the sewage pipe, the U-shaped flow channel will block the drainage at one end under the action of the baffle, so that it can only flow out through the drainage port at one end until the filter frame connected to the drainage port accumulates more impurities through filtration and becomes blocked. At this time, the cylinder pushes the U-shaped flow channel to slide on the support seat, and at the same time, the sewage pipe can be located at the other end of the baffle. Therefore, the wastewater can be introduced into the water collection tank at the other end through the drainage port at the other end, so as to facilitate the cleaning of the blocked filter frame and continue to operate without reducing the efficiency of water treatment. At the same time, the U-shaped flow channel can be pushed by the cylinder to make the baffle located at the center of the sewage pipe, which can also achieve the effect of double flow.

[0022] like Figure 3The water collecting box 12 has an opening at the top, and two keels 13 are fixed to the inner top wall of the water collecting box 12 below the opening. The filter frame 14 is embedded in the water collecting box 12 and supported by the keels 13. The filter frame is embedded in the water collecting box, which can prevent the sewage from overflowing onto the water collecting box when it is introduced into the filter frame. At the same time, the filter frame is supported by the keels to improve its placement stability, and it is also convenient for the staff to take out the filter frame for cleaning.

[0023] The inner side of the water collecting tank 12 is fixed with an inclined plate 15 located above the overflow pipe 16, a gap is left between the left side of the inclined plate 15 and the inner wall of the water collecting tank 12, and the upper surface of the left end of the inclined plate 15 is in an arc shape. After the wastewater is filtered through the filter frame, it can flow down along the inner wall of the water collecting tank under the guidance of the inclined plate, thereby effectively preventing the water source from splashing and affecting the sedimentation effect in the water collecting tank.

[0024] In addition, a pump body 17 connected to the bottom of the two water collecting tanks 12 is installed on the table top of the operating table 1. The bottom of the water collecting tank 12 is conical, and the water delivery end of the pump body 17 is connected to the top of the outer side of the two filter cartridges 2. The impurities left in the water collecting tank can be extracted by the pump body and introduced into the filter cartridge for filtering again, so as to achieve the effect of circulating filtration.

[0025] At the same time, a backwash pipe 18 is installed at the bottom of the two filter cartridges 2. Water is introduced into the backwash pipe, and the water backwashes the filter layer in the filter cartridge from bottom to top, and then the washed impurities are discharged through the water inlet pipe, thereby increasing the service life of the filter cartridge and avoiding blockage to reduce the filtering effect and efficiency.

[0026] The working principle of the above embodiment is:

[0027] The sewage is guided to the filter cartridge for filtration through the water inlet pipe. The filtered water source will enter the mixing box through the water guide pipe. At this time, the medicine inlet pipe adds medicine inside, and the mixing box is turned on for stirring, so that the wastewater and the medicine are fully mixed to filter out impurities. When the stirring is completed, the sewage is discharged through the sewage pipe, and the wastewater is guided to the two filter frames through the U-shaped flow channel to complete the filtration. Then, when falling, with the assistance of the inclined plate, the water source can flow down along the inner wall of the water collection tank, thereby reducing the impact of the water source falling. At the same time, the pump body can extract the water source in the water collection tank and guide it into the filter cartridge again for filtration treatment, thereby realizing the circulation treatment and improving the effect of water source treatment. At the same time, it can also be precipitated through the water collection tank until it overflows and is discharged through the overflow pipe;

[0028] In another case, the U-shaped flow channel is pushed by the cylinder to slide on the support seat, so that the baffle can be located in the middle of the sewage pipe, and the double-channel guidance can also be achieved. At the same time, the U-shaped flow channel can be pushed by the cylinder to make the sewage pipe located on the left and right sides of the baffle, so as to achieve single-channel sewage discharge. This method can facilitate the clogging of the filter frame on one side, and then push it to the other side, and connect it with another water collecting tank through the flow channel at the other end, so as to facilitate the removal of the filter frame for cleaning or replacement;

[0029] When the filtration efficiency of the filter cartridge decreases, water is directed through the backwash pipe, the pipes connected to the pump body and the water pipe are closed, and the water inlet pipe is opened, so that the impurities in the filter cartridge can be directed into the sewage pool through backwashing;

[0030] In summary, it can be filtered through the filter cartridge, mixed with the reagents in the mixing box, and precipitated through the filter frame and the water collecting tank. Under the action of the pump body, circulating filtration can be achieved, thereby effectively improving the effect and efficiency of wastewater treatment.
