Description

Technical Field

[0001] The utility model belongs to the technical field of road cleaning equipment, and in particular relates to a sewage recovery garbage box and a washing and sweeping vehicle. Background Art

[0002] The emergence of cleaning and sweeping vehicles not only greatly reduces the labor intensity of sanitation workers, but also improves cleaning efficiency.

[0003] A washing and sweeping truck has multiple working modes, two of which are mainly. One is a pure cleaning mode in which the sweeping brush set on the side of the bottom of the truck sweeps the garbage on the road into the suction cup working space located in the middle part of the bottom of the truck. The suction cup sucks up the garbage at the bottom of the truck and sends it into the garbage bin inside the truck. The other is a combination of washing and sweeping mode, that is, water is sprayed to reduce dust and flush the road surface during the cleaning process. Not only does it clean the road surface and reduce dust being raised, but the garbage is also not easy to escape from under the suction cup after being sprayed with water. The cleaning effect is better than the pure cleaning mode.

[0004] The washing and sweeping vehicle not only needs to be equipped with a water tank for holding clean water, but also a garbage bin for storing garbage. Given the limited volume of the washing and sweeping vehicle, the water tank cannot be set too large, and the volume of the water tank directly affects the length of time for spraying water during the cleaning process. If the water in the water tank is used up ahead of time, the washing and sweeping vehicle can only clean the road surface in pure cleaning mode, and the cleaning effect will also be worse. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a sewage recovery garbage bin, which can recover and purify the sewage in the garbage bin and then recycle it, thereby saving water resources and improving the cleaning effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] Preferably, the first filter partition is fixedly arranged in parallel with the horizontal plane on the side plate and the connecting plate on the side corresponding to the sewage suction port in the box, and the height of the plane where the first filter partition is located is higher than the first top plate and lower than the second top plate; the second filter partition is fixedly arranged in the box perpendicular to the first filter partition, and the edges of the second filter partition are respectively fixed on the first filter partition, the connecting plate, the first top plate, the back plate, and the first bottom plate, that is, the first filter partition and the second filter partition are in an inverted L shape; when the garbage dumping door is closed, the edges of the first filter partition and the second filter partition close to the garbage dumping door are in contact with the garbage dumping door; along the direction from the garbage dumping door to the back plate, the box is divided into mutually embedded rectangular spaces and inverted L-shaped spaces by the first filter partition and the second filter partition.

[0010] Preferably, the first bottom plate is arranged to be inclined downward toward the garbage dumping door.

[0011] Preferably, the box body also includes a filter barrel, which is arranged above the first bottom plate in the inverted L-shaped space, with an open top and a hollow interior. The bottom of the filter barrel is connected to one end of a pipe passing through the first bottom plate, and the other end of the pipe is connected to the filter.

[0012] Preferably, the top of the filter barrel is provided with a circle of outward-turned eaves.

[0013] Preferably, the box body also includes a wave-breaking plate, which is arranged in an inverted L-shaped space and is located behind the filter barrel near the back plate. Both sides of the wave-breaking plate are respectively fixed on the second filter baffle and the inner surface of the side plate close to the filter barrel, and the bottom of the wave-breaking plate does not contact the first bottom plate.

[0014] Preferably, the box body further includes a second spray bar, and the second spray bar is arranged on the inner surface of the side plate opposite to the second filter baffle in the inverted L-shaped space.

[0015] Preferably, the box body further includes a first spray bar, and the first spray bar is arranged on the lower surface of the second top plate opposite to the first filter baffle in the inverted L-shaped space.

[0016] The utility model also provides a washing and sweeping vehicle, which adopts the above-mentioned sewage recovery garbage box.

[0017] The beneficial effects of the utility model are:

[0018] (1) In the prior art, when the washing and sweeping vehicle is in a combined washing and sweeping mode, the suction cup will suck in some sewage into the garbage bin while sucking in the garbage, thus occupying the space for storing the garbage in the garbage bin. The sewage recovery garbage bin of the utility model can store large garbage at the same time, and through the filtering function of the filtering baffle and the filtering barrel and the specific position setting, the sewage in the bin enters the filtering barrel after sedimentation and filtering treatment for more than one time and flows out of the sewage recovery garbage bin. This not only reduces the problem of garbage storage space occupation caused by the sewage in the garbage bin, but also the sewage discharged from the sewage recovery garbage bin of the utility model basically contains only a small amount of sewage, that is, extremely small gravel and dust. This sewage can be directly used to flush heavily dirty roads, thus saving water.

[0019] (2) The utility model also mixes the sewage flowing out of the sewage recycling garbage bin with the clean water in the water tank, and then performs a final purification (dust reduction and pollution removal) at the filter. Mixing the sewage flowing out of the sewage recycling garbage bin with the clean water in the water tank can improve the cleanliness of the sewage. Performing the final purification at the filter can further improve the overall cleanliness of subsequent water spraying. At the same time, because the sewage flowing out of the sewage recycling garbage bin is already relatively clean, the purification speed of the filter is greatly shortened. The technicians can adjust the mixing ratio of the two water sources according to the dirtiness of the road surface, thereby further improving the utilization efficiency of water resources while ensuring the cleaning effect of the road surface.

[0020] (3) The sewage suction port is located in the rectangular space inside the box, so the garbage entering the box from the sewage suction port will first enter the rectangular space, and because it is intercepted by the filter baffle, the larger garbage in the rectangular space is stored in the rectangular space, and the sewage containing mud and dust can pass through the filter baffle into the inverted L-shaped space. In addition, the height of the plane where the first filter baffle is located is higher than the first top plate and lower than the second top plate, that is, the larger garbage in the rectangular space will not escape from the air suction port of the fan due to the suction force of the fan; at the same time, it also avoids the situation where the air suction port of the fan is blocked by garbage, and guarantees the air volume required for the normal operation of the fan to the greatest extent.

[0021] (4) After the sewage containing mud, sand and dust is intercepted by the filter baffle, the flow rate is greatly reduced, and the speed of the cleaning and sweeping vehicle during operation is relatively slow, so the flow rate of the sewage entering the inverted L-shaped space is relatively stable; in this environment, the mud in the sewage is very easy to settle, so as the level of the sewage in the inverted L-shaped space rises, the mud in the sewage in the inverted L-shaped space settles to the upper surface of the first bottom plate until the sewage in the inverted L-shaped space is higher than the bottom of the filter barrel. The sewage above the bottom of the filter barrel is filtered again by the filter barrel body and flows into the filter barrel from the outer wall of the barrel body. At this time, the sewage entering the filter barrel has been purified through two filtrations and one mud sedimentation, and is relatively clean.

[0022] (5) When the water flow rate through the filter baffle is too high, and the flow rate of the sewage filtered through the filter barrel body is too low, the overall sewage water level in the box will rise, reducing the space for storing garbage. The top of the filter barrel of the utility model is open. When the sewage after sedimentation is higher than the top of the filter barrel, it will flow into the filter barrel from the top of the filter barrel. The water quality of this part of the sewage has been greatly improved. At the same time, the sewage height in the box is guaranteed, so that the space for storing garbage will not be excessively occupied by sewage.

[0023] (6) The second spray bar and / or the first spray bar in the utility model can spray water toward the opposite filter baffle to flush out the blockage in the filter through hole of the filter baffle, thereby improving the filtering capacity of the filter baffle in subsequent work.

[0024] (7) The purification and recycling of sewage in the sewage recovery garbage bin in the utility model are carried out simultaneously during the working process of the washing and sweeping vehicle. Compared with the prior art of using chemical agents to produce flocculent precipitation of sewage in the garbage bin to purify water, the utility model not only does not use the high cost of chemical agents, but also greatly shortens the water purification cycle compared with chemical agents.

[0035] When the washing and sweeping vehicle is in the washing and sweeping combined mode, the debris sucked in by the suction cup of the washing and sweeping vehicle mainly includes garbage, mud, and sewage.

[0036] like Figure 1 to Figure 4As shown, a sewage recycling garbage bin of the utility model comprises a garbage bin 1, a fan 2, a one-way valve 3 and a filter 5. A sewage suction port 11 is arranged at one end of the top of the garbage bin 1, a fan 2 is arranged at the other end of the top of the garbage bin 1, the bottom of the garbage bin 1 is connected with the filter 5 through a pipeline, and a one-way valve 3 is also arranged on the pipeline between the bottom of the garbage bin 1 and the filter 5, and the flow direction of the one-way valve 3 is from the garbage bin 1 to the filter 5.

[0037] Specific:

[0038] The garbage bin 1 further comprises a box body 17 and a second filter partition 14b arranged in the box body 17. The box body 17 comprises a first top plate 17a, a second top plate 17b, a first bottom plate 17c, a garbage dumping door 17e, a side plate 17f, and a back plate 17g. The first top plate 17a and the second top plate 17b are arranged adjacent to each other at the top of the box body 17 along the length direction, and the height of the first top plate 17a in the vertical direction is less than the height of the second top plate 17b in the vertical direction. The first top plate 17a and the second top plate 17b are connected by a connecting plate (not numbered in the figure), that is, the first top plate 17a, the second top plate 17b and the connecting plate are arranged at the top of the box body 17 in two steps; the bottom of the box body 17 comprises a first bottom plate 17c arranged obliquely downwardly toward the garbage dumping door 17e, and the angle between the first bottom plate 17c and the horizontal plane is denoted as θ; the side surface of the box body 17 used to connect the top and bottom of the box body 17 comprises The back panel 17g, two side panels 17f and a garbage dumping door 17e. The upper end of the garbage dumping door 17e is movably hinged on a side of the second top panel 17b away from the first top panel 17a in the length direction. When the garbage dumping door 17e is lifted up and opened, the garbage and sewage in the box body 17 can be poured out. When the garbage dumping door 17e is closed, the upper surface of the first bottom panel 17c close to the garbage dumping door 17e is tightly fitted with the bottom of the garbage dumping door 17e. The back panel 17g is arranged opposite to the garbage dumping door 17e. The upper edge of the back panel 17g is fixedly connected to the side of the first top panel 17a away from the second top panel 17b in the length direction, and the lower edge of the back panel 17g is fixedly connected to the side of the first bottom panel 17c away from the garbage dumping door 17e. The other two sides of the back panel 17g are respectively fixedly connected to the side panels 17f.

[0039] The first top plate 17a is inclined below the horizontal plane to help the garbage and sewage in the box body 17 to accumulate toward the garbage dumping door 17e, so that the garbage and sewage will not block the sewage suction port 11; and when the garbage dumping door 17e is opened, the garbage and sewage that have accumulated for a long time will automatically flow out.

[0040] Optionally, the bottom of the box body 17 also includes a second bottom plate 17d, one side of the second bottom plate 17d along the length direction is fixedly connected to the side of the first bottom plate 17c close to the garbage dumping door 17e, and the second bottom plate 17d is parallel to the horizontal plane, and the bottom of the garbage dumping door 17e is tightly fitted with the upper surface of the second bottom plate 17d.

[0041] The second bottom plate 17d is used to closely cooperate with the garbage dumping door 17e, further improving the sealing performance of the garbage dumping door 17e when it is closed.

[0042] In this embodiment, the angle θ between the first bottom plate 17c and the horizontal plane is 25°; the second bottom plate 17d is 20 mm wide; the edge where the garbage dumping door 17e contacts the first bottom plate 17c and the side plate 17f (or the edge where the garbage dumping door 17e contacts the upper surface of the second bottom plate 17d and the inner surface of the side plate 17f) is provided with sealing rubber, and when the garbage dumping door 17e is closed, the garbage and sewage in the garbage bin 1 will not leak out.

[0043] The first filter baffle 14a is fixedly arranged parallel to the horizontal plane on the side plate 17f and the connecting plate on the side corresponding to the sewage suction port 11 in the box body 17. The height of the plane where the first filter baffle 14a is located is higher than the first top plate 17a and lower than the second top plate 17b; the second filter baffle 14b is fixedly arranged in the box body 17 perpendicular to the first filter baffle 14a, and the edges of the second filter baffle 14b are respectively fixed on the first filter baffle 14a, the connecting plate, the first top plate 17a, the back plate 17g, and the first bottom plate 17c, that is, the first filter baffle 14a and the second filter baffle 14b are in an inverted L shape; looking from the garbage dumping door 17e into the box body 17, the box body 17 is divided into two mutually interlocking rectangular and inverted L-shaped spaces by the first filter baffle 14a and the second filter baffle 14b. When the garbage dumping door 17e is closed, the edges of the first filter partition 14a and the second filter partition 14b close to the garbage dumping door 17e are in close contact with the garbage dumping door 17e.

[0044] The first filter partition plate 14a and the second filter partition plate 14b intercept garbage with a size larger than the filter through holes through a plurality of filter through holes provided thereon and penetrating the first filter partition plate 14a and the second filter partition plate 14b.

[0045] The sewage suction port 11 is arranged on the first top plate 17a corresponding to the rectangular space in the box body 17, and the sewage suction port 11 leads to the interior of the box body 17; the fan 2 is arranged on the second top plate 17b at one end away from the sewage suction port 11 and close to the back plate 17g, and the exhaust port of the fan 2 is located in the inverted L-shaped space in the box body 17, which is used to extract the air in the box body 17 so that the gas in the box body 17 is in a relatively negative pressure state.

[0046] In the utility model, the sewage suction port 11 is located in the rectangular space in the box body 17, so the garbage entering the box body 17 from the sewage suction port 11 will first enter the rectangular space, and because it has been intercepted by the first filter partition 14a and the second filter partition 14b, the garbage with a larger volume in the rectangular space is stored in the rectangular space, and the sewage containing mud and dust can enter the inverted L-shaped space through the filter partition 14. In addition, the height of the plane where the first filter partition 14a is located is higher than the first top plate 17a and lower than the second top plate 17b, that is, the garbage with a larger volume in the rectangular space will not escape from the air suction port of the fan 2 due to the suction force of the fan 2; at the same time, it also avoids the situation that the air suction port of the fan 2 is blocked by garbage, and the air volume required for the normal operation of the fan 2 is guaranteed to the greatest extent, that is, the operation effect of the suction cup (not shown in the figure) connected to the sewage suction port 11 is guaranteed.

[0047] The trash bin 1 further includes a second spray bar 13 disposed in the bin body 17. The second spray bar 13 is disposed on the inner surface of the side plate 17f in the inverted L-shaped space, opposite to the second filter baffle 14b. The second spray bar 13 sprays water toward the second filter baffle 14b to flush out the blockage in the filter through hole of the second filter baffle 14b, so as to improve the filtering capacity of the second filter baffle 14b in subsequent work.

[0048] Optionally, the trash bin 1 further comprises a first spray bar 12 disposed in the bin body 17, the first spray bar 12 being disposed on the lower surface of the second top plate 17b in the inverted L-shaped space, opposite to the first filter baffle 14a. The first spray bar 12 sprays water toward the first filter baffle 14a to flush out the blockages in the filter through holes of the first filter baffle 14a, so as to improve the filtering capacity of the first filter baffle 14a in subsequent work.

[0049] The spray head angles of the first spray bar 12 and / or the second spray bar 13 can be adjusted manually, and the water sprayed by the first spray bar 12 and / or the second spray bar 13 comes from the water tank containing clean water or the sewage in the garbage bin 1.

[0050] The garbage bin 1 further comprises a filter barrel 16 arranged in the box body 17. The filter barrel 16 is arranged in the inverted L-shaped space near the garbage dumping door 17e. The top of the filter barrel 16 is open, the interior of the filter barrel 16 is hollow, the bottom of the filter barrel 16 is connected to one end of the pipe, the pipe passes through the first bottom plate 17c, and the other end of the pipe is connected to the filter 5 arranged on the lower surface of the first bottom plate 17c; a one-way valve 3 is arranged on the pipe between the filter barrel 16 and the filter 5. The portion of the first bottom plate 17c through which the pipe passes is sealed and waterproof. The bottom of the filter barrel 16 is spaced apart from the upper surface of the first bottom plate 17c by a set distance. Looking from the top 4 of the box body 17 into the box body 17, the filter barrel 16 and the fan 2 are arranged at the front and rear positions on the same side. When there is no sewage in the filter barrel 16, the valve flap of the one-way valve will be closed due to the suction force of the fan 2.

[0051] The bottom of the filter barrel 16 is made of water-impermeable material, and the body of the filter barrel 16 is made of porous filter material.

[0052] In this embodiment, the set distance between the bottom of the filter barrel 16 and the upper surface of the first bottom plate 17c of the filter barrel 16 at the closest interval is 40 mm.

[0053] After the sewage containing silt and dust is intercepted by the first filter baffle 14a and the second filter baffle 14b, the flow rate is greatly reduced, and the speed of the washing and sweeping vehicle during operation is relatively slow, so the flow rate of the sewage entering the inverted L-shaped space is relatively stable; in this environment, the silt in the sewage is very easy to settle, so as the level of the sewage in the inverted L-shaped space rises, the silt in the sewage in the inverted L-shaped space settles to the upper surface of the first bottom plate 17c, until the sewage in the inverted L-shaped space is higher than the bottom of the filter barrel 16, the sewage above the bottom of the filter barrel 16 is filtered again by the barrel body of the filter barrel 16, and then flows into the filter barrel 16 from the outer wall of the barrel body. When the sewage in the inverted L-shaped space is higher than the top of the filter barrel 16, the sewage above the top of the filter barrel 16 flows into the filter barrel 16 from the top of the filter barrel 16. The sewage in the filter barrel 16 passes through the pipe at the bottom of the filter barrel 16, flows through the one-way valve 3, and enters the filter 5.

[0054] In the utility model, the filter barrel 16 and the fan 2 are arranged at the front and rear positions on the same side. Compared with directly arranging the fan 2 above the filter barrel 16, this avoids the situation where the sewage near the filter barrel 16 is pushed into the filter barrel 16 by the airflow of the suction fan before the sediment is completely settled.

[0055] At the same time, when the water flow rate passing through the first filter baffle 14a and the second filter baffle 14b is too large, and the flow rate of the sewage filtered through the filter barrel 16 is too small, the overall sewage water level in the box 17 will rise, reducing the space for storing garbage. The top of the filter barrel 16 of the utility model is open. When the sewage after sediment precipitation is higher than the top of the filter barrel 16, it will flow into the filter barrel 16 from the top of the filter barrel 16. The water quality of this part of the sewage has been greatly improved. At the same time, the sewage height in the box 17 is also guaranteed, so that the space for storing garbage will not be excessively occupied by sewage.

[0056] Optionally, a circle of outward-turned eaves 16a is provided on the top of the filter barrel 16. When the sewage near the filter barrel 16 is slightly bumped by the washing and sweeping vehicle, sewage waves will occur, which makes it possible for sewage with a water level lower than the top of the filter barrel 16 to enter the filter barrel 16, and sewage waves are easy to bring up sediment, resulting in poor water quality of the sewage in the filter barrel 16 in the machine, containing a large amount of sediment; and the outward-turned eaves 16a can well reduce the probability of sewage near the filter barrel 16 entering the filter barrel 16 due to small waves.

[0057] Optionally, the trash bin 1 further includes a wave-breaking plate 15 arranged in the inverted L-shaped space perpendicular to the horizontal plane, and the two sides of the wave-breaking plate 15 are respectively fixed on the second filter partition 14b and a side plate 17f, and the wave-breaking plate 15 is located at a position near the back plate 17g behind the filter barrel 16, that is, when viewed from the top 4 of the box body 17 into the box body 17, the wave-breaking plate 15 is located between the filter barrel 16 and the fan 2, and at the same time, the bottom of the wave-breaking plate 15 does not contact the first bottom plate 17c, and the top of the wave-breaking plate 15 is higher than the top of the filter barrel 16. The distance between the wave-breaking plate 15 and the first bottom plate 17c will not block the movement of the silt deposited on the upper surface of the first bottom plate 17c, and at the same time, the existence of the wave-breaking plate 15 makes it possible for a large sewage surge carrying a large amount of silt caused by the washing and sweeping vehicle at the back plate 17g when the washing and sweeping vehicle brakes suddenly to enter the filter barrel 16 from the top of the filter barrel 16, further ensuring the water purification effect of the trash bin 1 of the utility model.

[0058] In this embodiment, the bottom of the wave-breaking plate 15 is at the same height as the middle of the filter barrel 16 .

[0059] The filter 5 is equipped with a tee, one water inlet is connected to the pipe at the bottom of the garbage bin 1, and the other water inlet is connected to the water tank pipe containing clean water. According to cleaning requirements, technicians can set the valve openings of the two water inlets so that the sewage that has undergone preliminary purification in the garbage bin 1 is mixed with the clean water, and then flows out after final purification by the filter 5, and reaches the required water spraying device of the washing and sweeping vehicle under the action of the water pump 4.

[0060] The sewage recovery garbage bin of the utility model can be used to store clean water when no garbage is loaded. Without changing the original volume of the washing and sweeping vehicle, the initial loading amount of the clean water is increased, the water spraying time of the washing and sweeping vehicle is prolonged, and the cleaning effect of the washing and sweeping vehicle is improved.

[0061] In the prior art, when the washing and sweeping vehicle is in a combined washing and sweeping working mode, the suction cup will suck in some sewage into the garbage bin while sucking in the garbage, occupying the space for storing garbage in the garbage bin. The sewage recovery garbage bin of the utility model, while storing larger garbage, also uses the filtering functions of the first filter baffle 14a and the second filter baffle 14b, the filter barrel 16 and the specific position setting to allow the sewage in the bin to enter the filter barrel 16 after sedimentation and more than one filtering treatment and flow out of the sewage recovery garbage bin. This not only reduces the problem of garbage storage space occupation caused by the sewage in the garbage bin, but also the sewage flowing out of the sewage recovery garbage bin of the utility model basically contains only a small amount of sewage containing extremely small gravel and dust. This sewage can be directly used to flush heavily dirty roads, saving water resources.

[0062] The utility model also mixes the sewage flowing out of the sewage recovery garbage box with the clean water in the water tank, and then performs a final purification (dust reduction and pollution removal) at the filter 5. Mixing the sewage flowing out of the sewage recovery garbage box with the clean water in the water tank can improve the cleanliness of the sewage. Performing the final purification at the filter 5 can further improve the overall cleanliness of subsequent water spraying. At the same time, because the sewage flowing out of the sewage recovery garbage box is already relatively clean, the purification speed of the filter 5 is also greatly shortened. The technicians can adjust the mixing ratio of the two water sources according to the dirtiness of the road surface, which further improves the utilization efficiency of water resources while ensuring the cleaning effect on the road surface.

[0063] In addition, the purification and recycling of sewage in the sewage recovery garbage bin in the utility model are carried out simultaneously during the working process of the washing and sweeping vehicle. Compared with the prior art of using chemical agents to produce flocculent precipitation of sewage in the garbage bin to purify water, the utility model not only does not have the high cost of using chemical agents, but also greatly shortens the water purification cycle compared to chemical agents.

[0064] The utility model also provides a washing and sweeping vehicle, which adopts the sewage recovery garbage box as mentioned above.

[0065] The above are only preferred embodiments of the invention and are not intended to limit the invention of the invention. The technology, shape, and structure that are not described in detail in the invention are all known technologies.
