Description

Technical Field

[0001] The utility model relates to the technical field of sanitation equipment, in particular to a cleaning device for a water filter element of a sanitation vehicle. Background Art

[0002] A water filter is a filtering device that is widely used in the fields of sanitation equipment, etc. When used, it can filter out particulate impurities in the water to achieve the purpose of purifying water.

[0003] In the prior art, although the water filter of the sanitation vehicle can achieve the purpose of filtering out particulate impurities in the water, there are still many disadvantages in actual use. For example, the water filter in the prior art is difficult to achieve self-cleaning. When the filter in the water filter filters out the particulate impurities in the water, the impurities will remain on the surface of the water filter element. After using it for a period of time, the water filter needs to be cleaned manually to avoid clogging of the water filter, which increases the workload of the staff and makes the actual use effect of the water filter in the prior art less than ideal. Summary of the invention

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a device for cleaning the water filter element of a sanitation vehicle, which realizes automatic cleaning by reversely flushing the filter element of the water filter, thereby significantly reducing the workload of the staff.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sanitation vehicle water filter element cleaning device, including a clean water tank, a water pump, a water distribution pipe and a water filter;

[0007] The water outlet of the clean water tank is connected to the water inlet of the water filter through a first ball valve, the water outlet of the water filter is connected to the water inlet of the water pump through a second ball valve, and the water outlet of the water pump is connected to the water distribution pipe;

[0008] The water outlet of the clean water tank is also connected to the water inlet of the water pump through a fourth ball valve;

[0009] The water distribution pipe is also connected to a third ball valve, a fifth ball valve and a sixth ball valve; the other end of the third ball valve is connected to the water channel for cleaning and sweeping operations, and is used to control the water spraying of the cleaning and sweeping operation nozzle; the other end of the fifth ball valve is connected to the water outlet of the water filter; the other end of the sixth ball valve is connected to the clean water tank, and is used to return excess clean water to the clean water tank;

[0010] A seventh ball valve is connected to the pipeline between the water inlet of the water filter and the first ball valve, and the seventh ball valve is used for discharging sewage after flushing the filter element of the water filter.

[0011] Furthermore, the first ball valve, the second ball valve, the third ball valve, the fourth ball valve, the fifth ball valve, the sixth ball valve and the seventh ball valve are all pneumatic high-pressure ball valves.

[0012] Furthermore, the water pump is a high-pressure water pump.

[0013] The utility model adopts the above technical scheme, and has the beneficial effect that: the cleaning device of the utility model can be used to clean the filter element without manual disassembly of the filter element, and the filter element of the water filter can be directly backwashed with high-pressure water to achieve automatic cleaning, which significantly reduces the workload of the staff and improves the cleaning efficiency of the water filter element. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0015] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0016] like Figure 1 As shown, the utility model of the sanitation vehicle water filter element cleaning device includes a clean water tank 1, a water pump 5, a water distribution pipe 7 and a water filter (including a housing 3 and a filter element 6);

[0017] The water outlet of the clean water tank 1 is connected to the water inlet of the water filter through the first ball valve 2-1, the water outlet of the water filter is connected to the water inlet of the water pump 5 through the second ball valve 2-2, and the water outlet of the water pump 5 is connected to the water distribution pipe 7;

[0018] The water outlet of the clean water tank 1 is also connected to the water inlet of the water pump 5 through the fourth ball valve 4-1;

[0019] The water distribution pipe 7 is also connected to the third ball valve 2-3, the fifth ball valve 4-2 and the sixth ball valve 4-3; the other end of the third ball valve 2-3 is connected to the water channel for washing and sweeping operations, and is used to control the water spraying of the washing and sweeping operation nozzle; the other end of the fifth ball valve 4-2 is connected to the water outlet of the water filter; the other end of the sixth ball valve 4-3 is connected to the clean water tank 1, and is used to return excess water to the clean water tank 1 (when the water flow and pressure of the reverse flushing are too large, the sixth ball valve 4-3 can be opened to disperse the water flow and reduce the pressure);

[0020] A seventh ball valve 4-4 is connected to the pipeline between the water inlet of the water filter and the first ball valve 2-1. The seventh ball valve 4-4 is used for discharging sewage after flushing the water filter element 6. Particulate impurities attached to the outer surface of the water filter element 6 are discharged through the seventh ball valve 4-4.

[0021] In this embodiment, the first ball valve 2-1, the second ball valve 2-2, the third ball valve 2-3, the fourth ball valve 4-1, the fifth ball valve 4-2, the sixth ball valve 4-3 and the seventh ball valve 4-4 are all pneumatic high-pressure ball valves, and the water pump 5 is a high-pressure water pump 5.

[0022] The opening and closing actions of the pneumatic high-pressure ball valves on each pipeline are performed by button operation in the cab of the sanitation vehicle.

[0023] The working principle of this utility model:

[0024] 1. Working state of sanitation vehicle (non-water filter cleaning state): the first ball valve 2-1, the second ball valve 2-2, and the third ball valve 2-3 are all open, and the other ball valves are closed, and the vehicle performs normal cleaning operations. The solid arrow of the waterway indicates that the water in the water filter flows from the outside to the center, and the particulate impurities in the clean water are attached to the outer surface of the water filter element;

[0025] 2. Water filter cleaning state: the fourth ball valve 4-1, the fifth ball valve 4-2, the sixth ball valve 4-3, and the seventh ball valve 4-4 are all open, and the other ball valves are all closed. The water path goes to the direction indicated by the dotted arrow, and the water in the water filter flows out from the filter element 6. The above technology does not require manual removal of the filter element for cleaning, and reverse cleaning is directly performed by high-pressure water to achieve the purpose of cleaning the water filter element 6.

[0026] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
