[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In the following embodiments, Figure 1 and Figure 2 The first groove 4 and the second groove 5 shown are located on the ground, but the bottom surface shown in the figure is only a part of the bottom surface. This part being shown makes the screening module 3 partially suspended in the air, which is not the actual installed state. Figure 1 and Figure 2 It is only to demonstrate its positional relationship with the first groove 4 and the second groove 5.

[0028] Example 1

[0029] refer to Figures 1-3A cleaning system for a mixing tanker includes a cleaning platform 1, a connecting frame 2 connected to the cleaning platform 1, and a screening module 3 arranged side by side with the cleaning platform 1. The cleaning platform 1 is provided with an inclined water tank 11, and a water supply pipe 111 is provided at the highest point of the water tank 11 to maintain flowing water in the water tank 11. The screening module 3 is located below the lowest point of the water tank 11. The screening module 3 is connected to an external circulation system and transports water to the water supply pipe 111 through the external circulation system. The connecting frame 2 is provided with multiple water delivery modules 21.

[0030] In this design, the driver of the mixing tanker truck reverses the vehicle to the designated position on the cleaning platform 1, and then water is delivered to the inside of the mixing tanker truck through the water delivery module 21. The mixing tanker truck's own mixing function cleans the inside of the mixing tanker truck, and then the cleaned wastewater and sand are discharged into the water tank 11 in reverse. Under the action of the water tank 11, the sand and gravel are guided to the screening module 3 for solid-liquid separation. The water that is screened will be sent to the water delivery pipe 111 through the external circulation system.

[0031] In this way, the water tank 11 with flowing water can handle the cleaning of multiple mixing tank trucks at the same time, avoiding clogging of the water tank 11, and the cost is low. Multiple mixing tank trucks can share a single screening module 3.

[0032] It should also be noted that the peripheral circulation system adopts a water circulation system well known to those skilled in the art, which has the most basic functions of filtration, water supply and water replenishment. The water that is screened is filtered and then transported to the water supply pipe 111. Water can also be replenished when the water volume is insufficient.

[0033] More preferably, multiple water delivery modules 21 are slidably connected to the connecting frame 2, and the water delivery modules 21 can move along the width direction of the washing platform 1. The driver of the mixing tanker or other operators can adjust the position of the water delivery modules 21 by adjusting the parking position of the mixing tanker, thus increasing the flexibility of the system.

[0034] In this embodiment, the water supply module 21 includes a support block 211 slidably connected to the connecting frame 2 and a water supply pipe 212 connected to the support block 211. The water supply pipe 212 has an L-shaped structure and is connected to an external water source. The position of the water supply pipe 212 can be adjusted by sliding the support block 211 on the connecting frame 2, and the L-shaped structure ensures that the output end of the water supply pipe 212 is vertically downward.

[0035] In a preferred embodiment, the water supply pipe 212 is an L-shaped rigid pipe; in other embodiments, the water supply pipe 212 uses a combination of a horizontal rigid pipe and a vertical flexible pipe. It should also be noted that, regardless of whether it is a rigid pipe or a combination of both, the end connected to the external water source must be a flexible pipe to ensure the movement of the water supply pipe 212. Regarding the connection method between the flexible and rigid pipe, methods well-known to those skilled in the art can be used, or a clamp connection can be used to ensure a tight connection between the flexible and rigid pipe. The external water source can be a faucet or other structure with water supply capability.

[0036] It should also be noted that regarding the connection method between the support block 211 and the water supply pipe 212, a hole matching the water supply pipe 212 is opened on the support block 211. The hole and the water supply pipe 212 are either tightly fitted or fixedly connected.

[0037] In this embodiment, the sliding connection can be achieved by using a slide rail and slider combination method well known to those skilled in the art. Specifically, a slide rail (not shown in the figure) is provided on the connecting frame 2, and a slider (not shown in the figure) is provided on the support block 211.

[0038] In other embodiments, the sliding connection can also adopt the sliding rail and pulley combination method known to those skilled in the art, specifically by setting a sliding rail (not shown in the figure) on the connecting frame 2 and setting a roller (not shown in the figure) on the support block 211.

[0039] Both methods can achieve a sliding connection between the support block 211 and the connecting frame 2. Operators can choose the first or second method depending on the actual situation.

[0040] More preferably, the water conveying module 21 also includes a pull rod 213, which is arranged vertically and connected to the bottom of the support block 211.

[0041] In practical applications, because the support block 211 is relatively high, in order to facilitate the movement of the water delivery module 21 by the driver of the mixing tanker or other operators, a vertically arranged pull rod 213 is connected to the bottom of the support block 211. The operator can move the support block 211 and the water delivery pipe 212 by pulling the pull rod 213.

[0042] In this embodiment, the screening module 3 includes a base frame 31 and a fixing frame 32. The fixing frame 32 is connected to the base frame 31. An inclined screen 321 is provided inside the fixing frame 32. A solid output port 312 is provided inside the base frame 31. The solid output port 312 is located below the output end of the screen 321. A first groove 4 for collecting the screened material from the screen 321 and a second groove 5 for collecting the solid output from the solid output port 312 are also provided on a ground.

[0043] Specifically, by setting an inclined screen 321 inside the fixed frame 32, the sand and gravel can slide down along the inclined direction of the screen 321 and fall from the fixed output port to the second groove 5, avoiding the accumulation of sand and gravel on the screen 321. The wastewater after washing and the water in the water tank 11 will fall directly through the screen 321 to the first groove 4 for storage, which is convenient for the external circulation system to process and transport the water to the water supply pipe 111, thus avoiding water waste.

[0044] In other embodiments, the screening module 3 also includes a drive unit 33, an elastic component 311 is provided on the base frame 31, a fixed frame 32 is connected to the elastic component 311, the drive unit 33 is connected to one side of the base frame 31, the power output end of the drive unit 33 is connected to the fixed frame 32, and the drive unit 33 is used to drive the fixed frame 32 to vibrate.

[0045] More specifically, the elastic component 311 can be springs, of which there are four, and one end of each of the four springs is fixedly connected to the top of the base frame 31, and they are arranged in a rectangular pattern. On both sides of the fixing frame 32, there are four connecting pieces that match the positions of the springs. The positions of the connecting pieces can be found in [reference needed]. Figure 1 and Figure 2 The four connecting pieces are fixedly connected to four springs respectively. All of these fixed connections can be made by welding. Under the action of the four springs, the fixed frame 32 can sway on the base frame 31. The drive unit 33 can be a vibrating motor. If a vibrating motor is used, the entire vibrating motor is bolted to one side of the fixed frame 33, since the output end of the vibrating motor is itself. Furthermore, in a preferred embodiment, the screening module 3 can also be a circular vibrating screen well-known to those skilled in the art. That is, the elastic component 311 and the drive unit 33 are both basic components of a circular vibrating screen. Circular vibrating screens are existing technology in this field. For specific structures, please refer to the circular vibrating screen described in Baidu Encyclopedia, or to a single-axis elliptical vibrating screen disclosed in Chinese Patent CN102962198A. The purpose of setting up the drive unit 33, elastic component 311, etc., is to further prevent sand and gravel from accumulating on the screen 321. If the base frame 31, fixed frame 32, and screen 321 are sufficient to meet the screening requirements, then the drive unit 33, elastic component 311, etc., are not required.

[0046] More preferably, the base frame 31 is provided with symmetrically arranged guide plates 313, which are inclined and have gaps between them. The gaps are solid output ports 312, and the solid output ports 312 gradually narrow from top to bottom.

[0047] The function of the guide plate 313 is to prevent sand and gravel from flying away from the solid output port 312 on the base frame 31 when they are discharged. Moreover, the solid output port 312, which gradually narrows from top to bottom, can also guide the sand and gravel to accurately enter the second groove 5.

[0048] Preferably, by providing a ramp 12 on one side of the cleaning platform 1, vehicles entering the cleaning platform 1 can be prompted to slow down. Furthermore, a wheel anti-rollover structure 13 is provided on the cleaning platform 1 so that after the vehicle stops, the corresponding inlet and outlet on the mixing tank truck correspond to the water delivery module 21 and the water tank 11, respectively.

[0049] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make several improvements or modifications without departing from the principles of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
