[0036] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figure 1 and Figure 2 As shown, the car washing machine sewage treatment equipment provided in this embodiment includes a car washing machine sewage treatment equipment composed of a sewage treatment mechanism 2 installed on a casing 1, wherein the sewage treatment mechanism 2 includes a rotary drum filter frame 201 arranged inside the casing 1, a hollow shaft 203 fixed to the opposite side of the rotary drum filter frame 201 and connected to the inner wall bearing of the casing 1, and a driving device 202 fixed to the casing 1 for driving the rotary drum filter frame 201 to rotate. The interior of the rotary drum filter frame 201 is hollow, and a slag discharge pipe 204 extending to the outside at both ends is installed inside the hollow shaft 203. The ends of the slag discharge pipe 204 extend to the interior of the rotary drum filter frame 201 and the outside of the casing 1 respectively. A material receiving pipe 205 connected to the slag discharge pipe 204 is installed inside the rotary drum filter frame 201. The material receiving pipe 205 is horizontally arranged inside the rotary drum filter frame 201.

[0038] In order to improve the filtering effect of the sewage treatment unit 2, Figure 1 、 Figure 3-Figure 8 As shown, in this embodiment, the housing 1 is provided with a gear pump body 3 for flushing the sewage treatment mechanism 2; the gear pump body 3 is fixed to the outer surface of the top side of the housing 1, the outside of the fixing frame 501 is fixed with a first water delivery pipe 31 and a second water delivery pipe 32, and the upper surface of the fixing frame 501 is fixed with a multi-way pipe 33, the outer surface of the gear pump body 3 is fixedly connected with two delivery pipes 4, and the two delivery pipes 4 are fixedly connected to the water tank and the multi-way pipe 33 respectively. Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the housing 1 is provided with an adjustment mechanism 5 for use with the gear pump body 3, wherein the adjustment mechanism 5 includes a fixed frame 501, a sliding frame 502 and a swing arm 503, the sliding frame 502 is movably provided on the outside of the fixed frame 501, the swing arm 503 is rotatably mounted on the outer surface of the fixed frame 501, and the sliding frame 502 and the swing arm 503 are slidably matched, and the fixed frame 501 is provided with a guide structure for limiting the sliding frame 502.

[0039] like Figure 6-Figure 8 As shown, a pressure regulating head 34 is provided on the outside of the fixing frame 501. The pressure regulating head 34 includes a connector 341 provided on the outside of the fixing frame 501, a pressure regulating pipe 342 fixedly passing through the inside of the connector 341 and located on one side of the second water pipe 32, and an elastic buffer pad 343 fixed to one end of the pressure regulating pipe 342 and abutting against the bottom end of the second water pipe 32. The pressure regulating head 34 includes a connector 341, a pressure regulating pipe 342 and an elastic buffer pad 343. This design allows the flushing water flow to be subject to a certain resistance when passing through the pressure regulating head 34, thereby increasing the static pressure energy of the water flow and converting it into stronger flushing kinetic energy. The provision of the elastic buffer pad 343 not only ensures a tight connection between the pressure regulating head 34 and the second water pipe 32, but also can absorb the impact force during the flushing process to a certain extent, protecting the equipment from damage.

[0040] It should be noted that if Figure 6 and Figure 7 As shown, the pressure regulating head 34 is arranged perpendicular to the second water pipe 32, and after being adjusted by the regulating mechanism 5, the pressure regulating head 34 rotates and contacts the bottom end of the second water pipe 32. Since the design size of the pressure regulating head 34 is smaller than that of the second water pipe 32, when the fluid passes through the reduced cross-section, its speed will increase, and the static pressure energy will be converted into kinetic energy, which helps to enhance the flushing effect. The fixed frame 501 is composed of two horizontal plates distributed up and down and a vertical seat fixed between the two horizontal plates. The swing arm 503 is internally rotatably installed with a connecting shaft 504 connected to the bottom horizontal plate. The first water pipe 31, the second water pipe 32 and the pressure regulating head 34 are all multiple in number, and the number of the regulating mechanisms 5 corresponds to them. A connecting rod 7 is fixed between the two sliding frames 502 in the two adjacent regulating mechanisms 5. The second water pipe 32 is located above the drum filter frame 201 , and the position of the material receiving pipe 205 corresponds to the second water pipe 32 . When the drum filter frame 201 is being flushed, the flushed impurities will enter the material receiving pipe 205 in time.

[0041] In order to achieve stable transmission, in this embodiment, Figure 7 and Figure 8As shown, a roller 508 is rotatably mounted on the side of the sliding frame 502 near the swing arm 503. A chute 509 communicating with the outside is provided inside the swing arm 503. The roller 508 is in rolling connection with the inner wall of the chute 509. The guide structure includes a slide 505 and a guide rod 506. The side of the sliding frame 502 away from the roller 508 is fixed to the outer surface of the slide 505. The guide rod 506 is fixed between two vertical plates and extends through the interior of the slide 505. A buffer spring 507 is fixed between one of the vertical plates and the slide 505 and surrounds the outer surface of the guide rod 506. The rolling connection between the roller 508 and the chute 509 and the provision of the buffer spring 507 not only improves the smoothness and accuracy of adjustment, but also reduces mechanical wear and extends the service life of the device.

[0042] It is worth mentioning that the design innovation in this embodiment not only improves the filtering effect of the sewage treatment mechanism 2, but also enhances the flushing capacity through the flexible adjustment mechanism and the optimized pressure regulating head 34 design, thereby ensuring the stability and reliability of the equipment.

[0043] To further improve the flushing effect, Figure 1 、 Figure 3-Figure 5 As shown, the gear pump body 3 is provided with a drive mechanism 6 for adjusting the speed of the gear pump body 3 and cooperating with the adjustment mechanism 5; the drive mechanism 6 includes a gear transmission member, an adjustment structure 607 and a rack transmission assembly, wherein the rack transmission assembly is used to drive the adjustment mechanism 5 to reciprocate, and the adjustment structure 607 is installed on the outer surface of the gear pump body 3 to adjust the gear transmission member and the rack transmission assembly. The rack transmission assembly includes a rack 601, a gear 602 and a cam 603. The outer surface of the outermost fixed frame 501 rotates with a support shaft connected to the gear 602 and the cam 603. The gear 602 and the cam 603 are fixed to the outer surface of the support shaft. The rack 601 meshes with the gear 602 and drives the cam 603 to rotate and counteract the outer surface of the sliding frame 502; the rack transmission assembly realizes precise reciprocating motion control of the adjustment mechanism 5 through the meshing of the rack 601 and the gear 602, and the contact between the cam 603 and the sliding frame 502. This design ensures that the pressure regulating head 34 can be accurately connected to or disconnected from the second water supply pipe 32, thereby adjusting the flushing water flow.

[0044] Specifically, the gear transmission component includes a connecting frame 604 disposed on the outside of the gear pump body 3, a second drive gear 606 mounted at the upper and lower ends of the connecting frame 604, and a first drive gear 605 mounted on the outer surface of the gear pump body 3. The first drive gear 605 is connected and fixed to one of the transmission gears in the gear pump body 3 via a transmission shaft. The two second drive gears 606 are of different sizes and are distributed up and down. The two second drive gears 606 are driven by an adjustment structure 607 and are respectively engaged with the first drive gear 605. The drive mechanism 6 achieves precise adjustment of the speed of the gear pump body 3 through the gear transmission component. The two second drive gears 606 of different sizes can be engaged with the first drive gear 605 respectively, thereby providing different transmission ratios to meet the speed requirements under different flushing needs.

[0045] Among them, the adjustment structure 607 includes two motor seats 6071 fixed to the outer surface of the gear pump body 3, a drive motor 6072 fixed to the outer surface of the bottom motor seat 6071, and a screw 6073 rotatably installed between the two motor seats 6071 and fixed to the output shaft of the drive motor 6072. The external thread of the screw 6073 is connected to the connecting block 6074 fixed to the outer surface of the connecting frame 604, and the top of the rack 601 is fixed to the outer surface of the connecting block 6074.

[0046] To realize the detection of the second driving gear 606 and the first driving gear 605, as shown in FIG. Figure 5 As shown, a limit slot 6075 is defined on one side of the gear pump body 3 near the connecting bracket 604. A limit block 6076, fixed to the connecting block 6074, is slidably mounted within the limit slot 6075. Two pressure sensors 6077 are also mounted within the limit slot 6075. The sliding fit of the limit block 6076 within the limit slot 6075 ensures stable transmission of the gear transmission. Furthermore, the pressure sensors 6077 within the limit slot 6075 monitor pressure changes during transmission in real time, providing data support for equipment fault warnings and maintenance.

[0047] like Figures 1-8 As shown, the working principle of the car washing machine sewage treatment equipment provided in this embodiment is as follows:

[0048] When the present invention is in use, sewage enters the drum filter frame 201 in the housing 1, and the driving device 202 drives the drum filter frame 201 to rotate. The sewage is filtered inside the drum filter frame 201, and the filtered impurities will remain in the drum filter frame 201. The gear pump body 3 is used to transport water to flush the drum filter frame 201. At this time, the impurities are collected as waste residue through the material receiving pipe 205 and enter the slag discharge pipe 204 and are discharged from the outside of the housing 1.

[0049] When the flushing effect needs to be adjusted, the two second drive gears 606 are respectively engaged with the first drive gear 605 through the transmission cooperation of the driving motor 6072 and the screw 6073. Since the two second drive gears 606 and the first drive gear 605 are set in different sizes, the speed can be adjusted during driving. When the bottom second drive gear 606 moves upward, the engagement of the rack 601 and the gear 602 drives the cam 603 to rotate to the left. After the cam 603 rotates, it abuts against the sliding frame 502 and squeezes the swing arm 503, so that the pressure regulating head 34 is connected to the second water pipe 32. Since the design size of the pressure regulating head 34 is smaller than the second water pipe 32, when the fluid passes through the reduced cross-section, its speed will increase, and the static pressure energy will be converted into kinetic energy, which helps to enhance the flushing effect.

[0050] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction.
