Description

Technical Field

[0001] The utility model relates to the technical field of engineering car washing machines, in particular to a sludge separation and recovery device for engineering car washing machines. Background Art

[0002] A construction vehicle washer, also known as a wheel washer, automatically washes all types of construction vehicles, resolving the problem of road pollution caused by vehicles on urban construction sites. It is suitable for locations with potentially polluting roads, such as construction sites, waste disposal sites, quarries, and freight transfer yards.

[0003] Typically, a drainage channel is installed on the ground beneath the car wash machine to drain the wastewater generated during the washing process into a nearby sewage tank. Once the wastewater enters the sewage tank, it carries too much silt, so natural sedimentation is currently required. Once the silt settles to the bottom of the tank, the water above the silt layer is pumped away. Finally, workers use tools such as shovels to remove the sludge from the tank bottom. However, this operation is inefficient and cumbersome, and the sludge in the sewage tank is prone to bacterial growth and odor, which affects the surrounding environment. Utility Model Content

[0004] The present application provides a sludge separation and recovery device for an engineering car wash machine, which can solve the following problems: waiting for the silt to settle naturally before pumping out and cleaning it is inefficient, troublesome and easy to affect the surrounding environment.

[0005] In the present application, a sludge separation and recovery device for an engineering car washing machine is provided, comprising a filter portion, the filter portion being in the shape of a rectangular box opening upward, and mainly composed of a plurality of filter plates connected together, the filter portion being arranged at the outlet of the car washing machine drain, and being used to filter the sewage discharged from the drain, so that the silt remains in the filter portion, and two reeling components are arranged above the filter portion, each of the reeling components mainly comprising a driving motor, a reeling roller, and a rope wound on the reeling roller, the two reeling rollers respectively rotating on the left and right sides above the filter portion, The rotating shafts are parallel to each other and are driven to rotate by the two driving motors respectively. One end of each of the two ropes is wound around the winding roller, and the other end is respectively connected to the left and right ends of the filter part. The filter part is moved up and down by the synchronous winding or unwinding of the two winding and unwinding components; the filter plate on one side of the left and right sides of the filter part is set to be openable and closable, and the filter part is driven to rise on one side by a single winding and unwinding component to tilt one side of the filter part and open the filter plate on that side, so that the mud and sand collected in the filter part automatically slide down the inclined surface and are discharged thereby.

[0006] In one embodiment, a collection box is further included. The collection box is in the shape of a box with an upward opening. The collection box is slidably arranged horizontally beside the sewage tank and can be slid from outside the sewage tank to the openable and closable side of the filter part to collect mud and sand discharged from the filter part.

[0007] In one embodiment, a slide is fixedly provided on the side of the sewage tank in a straight line close to or away from the filter part, and the collection box is slidably connected to the slide along the direction of the slide. The slide can limit the collection box in the vertical direction so that it can slide horizontally, and the two ends of the slide are penetrated so that the collection box can slide out.

[0008] In one embodiment, at least three wheels are rotatably provided at the lower end of the collection box, and the wheels contact the ground.

[0009] In one embodiment, the filter plate that can be opened and closed is rotatably connected to the filter portion, and is provided with a small motor for driving its rotation, thereby realizing the opening and closing of this side.

[0010] In one embodiment, a rubber pad is provided on a side of the openable filter plate close to the filter portion, and the filter plate contacts the filter portion through the rubber pad.

[0011] In summary, in this application, a sludge separation and recovery device for an engineering car wash machine has the following beneficial effects compared to the prior art:

[0012] (1) The sewage generated during the flushing process will first enter the filter part through the drainage channel, and then fall into the sewage pool after the silt is filtered out by the filter part. This allows the staff to directly pump out the filtered water in the sewage pool without waiting for it to settle naturally before cleaning. This is more efficient and saves trouble. In addition, the process of sludge settling naturally in the sewage pool is omitted, making the sewage pool cleaner and less likely to breed bacteria and produce odor.

[0013] (2) When the sludge filtered out by the filter section accumulates to a certain level, the filter section is lifted up synchronously by the two retractable and unreeling components, so that it rises. Then, one retractable and unreeling component is held while the other continues to lift up, so that the filter section tilts toward the side that can be opened and closed. After the filter plate on this side is opened, the mud and sand collected by the filter section will automatically slide down along the slope and be discharged, which is convenient and quick.

[0022] See also Figure 1 、 Figure 2 、 Figure 3A sludge separation and recovery device for an engineering car washing machine includes a filter part 1, which is a rectangular box-shaped body with an upward opening. It is mainly composed of multiple filter plates 2 (a bottom plate and four side plates) connected together. One of the bottom plates and three of the side plates are fixedly connected by welding, and the remaining side plate is on one of the left and right sides, and the filter plate 2 is configured to be openable and closable.

[0023] See also Figure 2 The filter part 1 is arranged at the outlet of the car washing machine drain 5, and one end thereof is attached to the wall where the drain 5 is located. The filter plate 2 is covered with many filter holes. When the filter part 1 is lower than the drain 5, it can filter the sewage discharged from the drain 5 and leave the sediment in the filter part 1.

[0024] See also Figure 3 Two reeling and unreeling components 7 are provided above the filter section 1, and each of the reeling and unreeling components 7 is mainly composed of a driving motor 8, a reeling roller 9 and a rope 10 wound on the reeling roller 9. The two reeling rollers 9 rotate respectively on the left and right sides above the filter section 1, and their rotating shafts are both horizontal and parallel, and are driven to rotate by the two driving motors 8 respectively. The two driving motors 8 are both fixedly mounted on the wall above the filter section 1, and their output shafts are each fixedly connected to the rotating shaft of one of the reeling rollers 9. One end of the two ropes 10 is knotted and wound around the reeling roller 9, and the other end is connected to the left and right ends of the filter section 1 by tying. A through hole 4 is provided at each of the left and right ends of the filter section 1 for providing a knotting position for the rope 10. In this arrangement, the filter portion 1 is moved up and down by synchronously reeling or unreeling the two reeling and unreeling components 7; the filter portion 1 is driven to rise on one side by a single reeling and unreeling component 7, so that one side of the filter portion 1 is tilted and the filter plate 2 on that side is opened, so that the mud and sand collected in the filter portion 1 automatically slides down the inclined surface and is discharged thereby.

[0025] See also Figure 3 In one embodiment, the upper end of the filter plate 2 that can be opened and closed is rotatably connected to the filter part 1, and its rotating shaft is in the horizontal direction. A small motor 3 is provided to drive its rotation, so as to realize the opening and closing of this side. The housing of the small motor 3 is fixedly mounted on the filter part 1, and its output shaft is fixedly connected to the rotating shaft of the filter plate 2. With this arrangement, the structure is simple, easy to implement and the effect is relatively stable. Furthermore, a layer of rubber pad is adhered to the side of the filter plate 2 that can be opened and closed, close to the filter part 1, and contacts the filter part 1 through the rubber pad. With this arrangement, the connection between the filter plate 2 and the filter part 1 is tighter and the gap is smaller after closing, making it less likely for mud and sand in the sewage to leak out.

[0026] See also Figure 4 In one embodiment, a collecting box 11 is further included. The collecting box 11 is in the shape of a rectangular box with an opening facing upward. The collecting box 11 is slidably arranged beside the sewage tank 6 in the horizontal direction, and can be slid from the outside of the sewage tank 6 to the openable and closable side of the filter part 1 to collect the silt discharged by the filter part 1. It is more convenient to use this solution to collect the filtered silt.

[0027] See also Figure 4 The two chutes 13 are respectively located on both sides of the collection box 11, and the chutes 13 can limit the collection box 11 in the vertical direction so that it can slide horizontally. The end of the chute 13 close to the filter part 1 does not extend to the location of the filter part 1 (to avoid interference when the filter part 1 moves up and down), and the two ends of the chute 13 pass through, so that the collection box 11 can slide out and slide out (incompletely slide out) toward the side close to the filter part 1 to collect the sediment discharged by the filter part 1. When the sediment in the collection box 11 accumulates to a certain extent, it slides out (completely slides out) toward the side away from the filter part 1 to clear away the sediment collected by the collection box 11.

[0028] See also Figure 4 In one embodiment, the collecting box 11 is rotatably provided with four wheels 12 at the lower end thereof, and rolls on the ground by the wheels 12. This arrangement makes it more convenient for the collecting box 11 to slide.
