[0002] The primary filter plate is a device used for air filtration, commonly used in ventilation systems, air-conditioning systems and other fields. It has the characteristics of high filtration efficiency and low resistance. Its main function is to filter dust, pollutants and other impurities in the air to prevent these impurities from entering the back-end equipment and affecting the normal operation and service life of the equipment, while ensuring the cleanliness and quality of indoor air.

[0003] However, during use, the primary filter plate needs to be replaced regularly to ensure the air volume of the air conditioner and prevent impurities from entering the back-end equipment.

[0041] As a further improvement of the above-mentioned utility model, the bottom of the support frame (1) is also provided with a moving wheel with a brake device.

[0042] The working principle is as follows: before using the automatic cleaning device for the primary filter plate of the above-mentioned design structure, the operator first moves the utility model to a cleaning site for standby use, then connects the water inlet of the water inlet pipe (51) to an external water source and the air inlet of the air inlet pipe (53) to an external high-pressure air source, at which time the water inlet pipe control valve (52) and the air inlet pipe control valve (54) are both in a closed state; then, the operator connects the transmission mechanism (2), the water inlet pipe control valve (52), the air inlet pipe control valve (54), the nozzle (55) and the limit switch (7) to the control device (6), and finally, the operator adjusts the operation mode of the nozzle (55);

[0043] When in use, the operator starts the transmission motor (24) to work through the control device (6). During operation, the operator only needs to press the start button installed inside the device, and the device will automatically clean. During specific operation, when the lifting frame (42) rises or falls to the position set by the limit switch (7), the limit switch (7) sends a trigger signal to the control device (6). After the control device (6) receives the trigger signal, the control device (6) sends a transmission motor steering change signal to the transmission motor (24) to change the steering direction of the transmission motor output shaft, thereby realizing that the lifting platform (4) automatically drives the cleaning device (5) to move up and down on the support frame (1) to perform spray cleaning work;

[0044] When the cleaning device (5) moves up and down, the operator controls the flow rates of the water inlet pipe control valve (52) and the air inlet pipe control valve (54), as well as the operation mode of the nozzle (55) through the control device (6) to perform cleaning work.

[0045] In the water mode, the operator only needs to switch the nozzle (55) to the water mode and close the air inlet pipe control valve (54); the nozzle (55) can spray water to form a water column or water mist for cleaning the primary filter plate (8), wherein the size and spray angle of the water flow of the nozzle (55) can also be adjusted by the control device (6);

[0046] In the gas mode, the nozzle (55) is switched to the gas mode, the water inlet pipe control valve (52) is closed, and the nozzle (55) can spray out high-pressure air to form a strong airflow for use in soot blowing, cleaning, drying, etc. of the primary filter plate (8). The size and spraying direction of the airflow of the nozzle (55) can also be adjusted by the control device (6).

[0047] In the water-gas mode, the operator only needs to open the air inlet pipe control valve (54) and the water inlet pipe control valve (52), and the nozzle (55) can mix the water flow and the high-pressure air and spray them out to form a water-gas mixture for cleaning the primary filter plate (8). The water-gas ratio and the spraying effect of the nozzle (55) can also be adjusted by the control device (6);

[0048] During use, water and high-pressure air are mixed through corresponding pipes and sprayed out by the nozzle (55). The water and high-pressure air are used in combination to achieve the purpose of cleaning the surface of the primary filter plate (8); the high-pressure air can effectively blow away the dust and dirt on the surface of the primary filter plate (8). Since the high-pressure air has a high speed and flow rate, it can blow away the dust and dirt from the surface and take away the water and grease therein. This cleaning method is particularly suitable for dirt and residues on the surface, such as food residues, dust, grease and dirt.

[0049] Secondly, the water can further clean the surface of the primary filter plate (8). By mixing water with high-pressure air, a soft water spray effect can be formed. This effect can wash away the dust and dirt on the surface of the primary filter plate (8) and make the surface smoother and cleaner. This cleaning method is suitable for various surfaces, such as glass, metal, plastic and ceramic tile.

[0050] In addition, the combination of water and high-pressure air can also be used to clean hard-to-reach areas. For example, when cleaning pipes or slits, high-pressure air can be used to inject water and gas into them, thereby flushing out the dirt and residue inside. This cleaning method is particularly suitable for hard-to-reach areas such as slits, pipes and containers.

[0051] Compared with the prior art, the utility model has the following beneficial effects:

[0052] 1. The utility model adopts water-gas mixed cleaning technology, which can clean the primary filter plate more quickly and thoroughly, improve the cleaning efficiency, and save time and labor costs;

[0053] 2. The utility model can directly clean the filter plate without disassembly, and can be directly washed with high-pressure water and gas in the air-conditioning box, which reduces maintenance downtime, improves equipment availability and production efficiency, saves water resources and manpower, and improves construction efficiency;

[0054] 3. The utility model has a high degree of automation, which reduces the need for manual operation, reduces cleaning costs, and also reduces water waste;

[0055] 4. The utility model adopts automation technology, which reduces the exposure and risk of operators, reduces the possibility of work safety accidents, and at the same time can ensure the consistency and reliability of cleaning quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0118] Example 1

[0119] Before using the automatic cleaning device for the primary filter plate of the above-mentioned design structure, the operator first moves the utility model to the cleaning site for standby use, then connects the water inlet of the water inlet pipe 51 to the external water source and the air inlet of the air inlet pipe 53 to the external high-pressure air source, at which time the water inlet pipe control valve 52 and the air inlet pipe control valve 54 are both in a closed state; then, the operator connects the transmission mechanism 2, the water inlet pipe control valve 52, the air inlet pipe control valve 54, the nozzle 55 and the limit switch 7 to the control device 6, and finally, the operator adjusts the operation mode of the nozzle 55;

[0122] Example 2

[0123] Embodiment 2 is basically the same as Embodiment 1, except that, in the water mode, the operator only needs to switch the nozzle 55 to the water mode, and the air intake control valve 54 is closed; the nozzle 55 can spray water to form a water column or water mist for cleaning the primary filter plate 8, wherein the size and spray angle of the water flow of the nozzle 55 can also be adjusted by the control device 6;

The size and spraying direction of the nozzle 55 airflow can also be adjusted by the control device 6.

[0125] The specific cleaning method is the same as that in Example 1 and will not be repeated here.

[0126] Example 3

[0127] Embodiment 3 is basically the same as Embodiment 1, except that, in the water-gas mode, the operator only needs to open the air inlet control valve 54 and the water inlet control valve 52, and the nozzle 55 can mix the water flow and the high-pressure air and spray out to form a water-gas mixture for cleaning the primary filter plate 8, wherein the water-gas ratio and the spraying effect of the nozzle 55 can also be adjusted by the control device 6;

[0128] During use, water and high-pressure air are mixed through corresponding pipes and sprayed out by the nozzle 55. The water and high-pressure air are used in combination to achieve the purpose of cleaning the surface of the primary filter plate 8. The high-pressure air can effectively blow away the dust and dirt on the surface of the primary filter plate 8. Since the high-pressure air has a high speed and flow rate, it can blow away the dust and dirt from the surface and take away the moisture and grease therein. This cleaning method is particularly suitable for dirt and residues on the surface, such as food residues, dust, grease and dirt.

[0129] Secondly, water can further clean the surface of the primary filter plate 8. By mixing water with high-pressure air, a soft water spray effect can be formed, which can wash away the dust and dirt on the surface of the primary filter plate 8 and make the surface smoother and cleaner. This cleaning method is suitable for various surfaces, such as glass, metal, plastic and ceramic tile.

[0130] In addition, the combination of water and high-pressure air can also be used to clean hard-to-reach areas. For example, when cleaning pipes or slits, high-pressure air can be used to inject water and gas into them, thereby flushing out the dirt and residue inside.
