[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] like Figure 1 As shown, a wastewater recycling tank includes a tank body 1 and a door 2. The lower part of the tank body is provided with at least two fixing posts 15, and the ends of the fixing posts are provided with flanges 16. The tank body can be installed at the rear of a cleaning vehicle using the flanges and fixing posts, facilitating assembly and disassembly. One side of the door is hinged to the tank body. The tank body is provided with a cylinder or hydraulic cylinder 3 for controlling the opening and closing of the door, realizing automated opening and closing control of the door, reducing the labor intensity of manual opening, and combining... Figure 3 and Figure 4As shown, the door is equipped with a filter barrel 4 and a slag discharge mechanism. The filter barrel includes a barrel body 401 and a bottom plate 402. One side of the bottom plate is hinged to the barrel body, and the other side is connected to the slag discharge mechanism for controlling the opening and closing of the bottom plate. The barrel body is located on the inner wall of the door. When the bottom plate flips downward along its hinge with the barrel body, the door can be opened, and the waste slag inside the barrel can be unloaded; conversely, when the bottom plate flips upward and abuts against the barrel body, the door can be closed. Figure 2 As shown, a vertical sewage pump 17 is installed on the outside of the tank. The suction port of the vertical sewage pump passes through the side wall of the tank and extends into the tank. The vertical sewage pump is located in the concave groove on the outside of the tank and can discharge the wastewater after it has been filtered by the filter barrel. Multiple liquid level sensors 18 are provided on one side of the tank, which are distributed from top to bottom to facilitate the automatic control of the vertical sewage pump according to the wastewater volume inside the tank.
[0030] like Figures 3 to 5 As shown, the slag discharge mechanism includes a winch 5 and multiple fixed pulleys. The winch's wire rope is turned by the pulleys and connected to a lifting ring 6 located on the bottom plate. The lifting ring is located on the side of the bottom plate away from its hinge to the barrel. When the winch winds up the wire rope, it causes the bottom plate to flip upwards to close; when the winch unwinds the wire rope, the bottom plate flips downwards under its own weight and the weight of the slag to open, allowing for slag removal. The winch is located on the outer wall of the barrel door, which has a rope-passing hole. The winch's wire rope passes through this hole and connects to the lifting ring. To improve the sealing at the rope-passing hole, a waterproof sealing joint is provided inside for the wire rope to pass through. The waterproof sealing joint in this embodiment is a commercially available product, specifically a 304 stainless steel waterproof cable connector from Jingteng Electronics. It uses an external thread connection for installation, providing good sealing, waterproofing, dustproofing, and rust resistance. In actual use, other commercially available products can also be used, as long as they do not obstruct the pulling of the wire rope and have a certain degree of sealing. A first fixed pulley 7 is provided on the outer wall of the box door, and a second fixed pulley 8 is provided on the upper part of the barrel. The winch's wire rope passes sequentially through the first fixed pulley, the rope hole, and the second fixed pulley before connecting to the lifting ring. The two fixed pulleys improve the stability and smoothness of opening and closing the bottom plate.
[0031] like Figure 1 and Figure 2 As shown, the upper part of the box is equipped with a wastewater recovery pipe connector 9 and a vacuum extraction pipe connector 10. A filter assembly is installed at the connection point between the vacuum extraction pipe connector and the box. Connecting the vacuum pump to the vacuum extraction pipe connector creates a negative pressure inside the box, drawing wastewater into the box through the wastewater recovery pipe connector. The inner end of the wastewater recovery pipe connector is located directly above the filter barrel. Combined with... Figure 6As shown, the filter assembly includes a protective cover 11, a positioning component 12, a filter frame 13, and a filter screen 14. The positioning component is connected to the housing. One side of the filter frame is pressed against the positioning component, and the other end is connected to the top wall of the housing. The filter screen is located inside the filter frame. The protective cover is located above the filter frame and connected to the housing. The filter screen effectively filters the exhaust gas, preventing waste residue mixed in the exhaust gas from entering the vacuum pump and causing damage to the vacuum pump. The filter frame is connected to the top wall of the housing with screws, which facilitates disassembly and replacement, reducing maintenance costs.
[0032] In use, this utility model is installed at the rear of the cleaning truck, without occupying space on the vehicle. The vacuum extraction pipe connector 10 is connected to the vacuum pump, and the wastewater recovery pipe connector 9 is connected to the wastewater recovery pipe of the cleaning equipment. The vacuum pump is started, creating negative pressure inside the housing 1. Wastewater and waste residue generated during the cleaning process are drawn into the housing 1 through the wastewater recovery pipe and fall into the filter tank 4, where the tank 401 filters the waste residue. During the vacuum pump's vacuuming process, fine waste residue mixed in with the exhaust gas is filtered by the filter screen 14. After cleaning, the cleaning truck is moved to the designated wastewater and waste residue recovery point, and the vertical sewage pump 17 is started to discharge the wastewater from the housing 1. After the wastewater is discharged, start the cylinder or oil cylinder 3 to open the box door 2, so that the filter barrel 4 is transferred to the outside of the box body 1 along with the box door 2. The winch 5 unwinds the wire rope 501, and the bottom plate 402 flips downward under its own weight and the weight of the waste residue. At this time, the waste residue falls and is unloaded. After the waste residue is cleaned up, the winch 5 winds up the wire rope 501, driving the bottom plate 402 to flip upward to close the bottom plate 402. Then close the box door 2.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
