Therefore, there is an urgent need for a stable and continuous dust reduction system. Utility Model Content

[0003] In view of the above problems, the utility model provides a sewage circulation dust suppression system for a road sweeper. The system uses a filtering device to filter the sewage and garbage mixture in a garbage collection box, and recycles the filtered sewage to achieve the purpose of continuous dust reduction and effectively save water resources.

[0004] A sewage circulation dust suppression system for a road sweeper includes a garbage bin, one of the sides of the garbage bin is an inclined surface, a sewage tank is connected to the outside below the inclined surface, a filter device is installed between the garbage bin and the sewage tank and on the inclined surface, the filter device is a structure with two layers of filter plates hinged to each other, the hinge point of the two layers of filter plates is located above the filter device, and each layer of the filter device is provided with a plurality of vertically arranged shear ribs.

[0005] Preferably, the filtering device comprises a bottom filter plate, a side surface of the bottom filter plate is hinged to the inclined surface, an upper filter plate is hinged to the upper end of the bottom filter plate, and a counterweight is provided at the lower end of the upper filter plate.

[0006] Preferably, both filter plates include a frame and a plurality of vertical shear ribs installed in the inner area of ​​the frame, the shear ribs of the bottom filter plate protrude from the upper surface of the frame, and the shear ribs of the upper filter plate protrude from the lower surface of the frame. When the two filter plates overlap, their respective shear ribs intersperse with each other to form a filtering structure with a filtering density twice that of a single filter plate.

[0007] Preferably, the counterweight blocks are multiple, and the multiple counterweight blocks are evenly arranged along the bottom edge of the upper filter plate.

[0008] Preferably, the counterweight blocks are arranged at intervals on the upper filter plate.

[0009] Preferably, a locking device is provided on the outer side surface of the inclined surface, and a hook is provided on the middle part of the upper end of the bottom filter plate. The hook penetrates the inclined surface outwardly and is detachably connected to the locking device.

[0010] Preferably, the sewage tank is provided with a liquid level display device.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. After the sewage mixture in the garbage bin is filtered by the filtering device, the sewage is separated, and then the sewage enters the negative pressure air inlet of the garbage bin through the water outlet of the sewage bin. The sewage and dry dust are fully mixed into liquid sludge before entering the garbage bin, so as to achieve the purpose of dust suppression.

[0014] 2. When dumping garbage, the center of gravity of the upper filter plate will change according to the change of the flipping angle of the garbage bin. When the flipping angle of the garbage bin makes the upper filter plate completely pass the center of gravity, the upper filter plate is completely flipped. Therefore, the upper filter plate and the lower filter plate form a shear force to shear and clean the accumulated garbage, so as to achieve the purpose of self-cleaning while unloading.

[0015] 3. The sewage circulation is self-circulating under the action of water level pressure difference and fan negative pressure, and there is no need to configure additional circulating water pumps. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] In response to the problems in the background technology, the technical solution of the present application is mainly to separate the sewage mixture entering the garbage bin. The specific implementation method is to expand the capacity of the garbage bin, add a sewage tank outside the garbage bin, and set a filtering device between the garbage bin and the sewage tank. The filtering device has a self-cleaning function to achieve the purpose of continuously filtering the sewage with garbage in the garbage bin into the sewage tank.

[0025] like Figure 1-5 As shown, the utility model discloses a sewage circulation dust suppression system for a road sweeper, wherein the garbage bin of the system is an inverted trapezoidal structure with a top area larger than a bottom area, the left and right sides of the inverted trapezoidal structure are vertical surfaces 9, the front and rear sides of the inverted trapezoidal structure are inclined surfaces 1 inclined inwardly, a sewage bin 8 is connected to the outside below the inclined surface, a through hole is processed between the garbage bin and the sewage bin and below the inclined surface, the garbage bin and the sewage bin are connected through the through hole, a filter device covering the through hole is installed on one side of the garbage bin on the inclined surface, the filter device includes a bottom filter plate 2 and an upper filter plate 5, the two filter plates are hinged to each other at the top, and the hinge point is located above the through hole. The bottom filter plate is connected to the inclined surface 1 by a hinge 3, and a counterweight is provided at the lower end of the upper filter plate. There are multiple counterweights, and the multiple counterweights are evenly arranged at intervals along the bottom edge of the upper filter plate.

[0026] Both filter plates include a frame and a plurality of vertical shear ribs installed in the inner area of ​​the frame. The shear ribs of the bottom filter plate 2 protrude from the upper surface of the frame, and the shear ribs of the upper filter plate 5 protrude from the lower surface of the frame. When the two filter plates overlap, their respective shear ribs intersect with each other to form a filtering structure with a filtering density twice that of a single filter plate. When the trash bin is dumped, the center of gravity position of the counterweight block 7 will change according to the change of the flip angle of the trash bin. When the flip angle of the trash bin makes the counterweight block 7 completely pass the center of gravity, the counterweight block 7 will drive the upper filter plate 5 to flip completely. Therefore, the upper filter plate 5 and the lower filter plate 2 form a shear force to shear and clean the accumulated garbage, so as to achieve the purpose of self-cleaning while unloading, so that the filtering device can continue to filter and operate stably.

[0027] In order to facilitate observation of the water volume in the sewage tank, a liquid level display device is provided in the sewage tank.

[0028] After the sewage mixture in the garbage bin is filtered by the plate filter device, the sewage is separated, and then the sewage enters the negative pressure air inlet of the garbage bin through the water outlet of the sewage bin, and then the sewage and dry dust are fully mixed into liquid sludge before entering the garbage bin, so as to achieve the purpose of dust suppression. Supplement: The entire upper and lower plate filter devices can also be opened and cleaned separately. The specific implementation method is that a hinge is provided on one side of the plate filter device, a locking device 7 is provided above the sewage tank side of the inclined surface 1, and a hook 6 is provided on the middle part of the upper end of the bottom filter plate 2. The hook passes through the inclined surface outward and is detachably connected to the locking device. Before cleaning, tighten the hook with the locking device, and when cleaning, release the locking device, flip the plate filter device, and the sludge in the sewage tank can be opened and cleaned.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
