[0031] Furthermore, the cleaning structure 4 includes a first conveyor roller 401, a spray head 402, and a sponge cleaning brush roller 403. Two groups of first conveyor rollers 401 are rotatably connected inside the cleaning tank 2. A spray head 402 is fixedly installed on the inner top wall of the cleaning tank 2. Three sponge cleaning brush rollers 403 located between the two groups of first conveyor rollers 401 are rotatably connected inside the cleaning tank 2.

[0032] Furthermore, the drying structure 5 includes a second conveyor roller 501, a drying air jet pipe 502, a drying chamber 503, an air heating box 504, an electric heater 505, and a blower 506. Two groups of second conveyor rollers 501 are rotatably connected inside the drying box 1.

A blower 506 is fixedly installed inside the drying chamber 503.

[0033] Example 1:

[0034] When the water circulation type automatic cleaning and drying equipment for fire hoses of the present invention is in operation, first, the fire hose to be cleaned is fed into the cleaning tank 2 through the material inlet 7, and the first conveyor roller 401 and the sponge cleaning brush roller 403 are used for preliminary cleaning in a physical contact manner. The spray head 402 will spray a cleaning liquid onto the surface of the fire hose to help remove stains.

[0035] The water purification and recycling structure 6 is one of the key components of the present invention; after cleaning, the wastewater containing dirt flows into the water purification chamber 602 in the equipment box 3 through the connecting pipe 601; the flocculant in the flocculant tank 603 is quantitatively added to the mixing tank 606 through the feeding pipe 604 and the control valve 605, and the driving motor 608 drives the stirring rod 607 to work, so that the water and the flocculant are fully mixed, thereby promoting the suspension particles in the sewage to agglomerate into larger lumps, facilitating subsequent filtration treatment.

[0036] The water that has been preliminarily purified in the mixing tank 606 will be introduced into the filter tank 609, and the filter cartridge 610 composed of the sponge filter inner layer 6101, the fiberglass intermediate layer 6102 and the activated carbon outer layer 6103 filters and purifies the water in multiple stages; the selection and combination of these filter materials can effectively remove different types of pollutants, including organic matter, inorganic salts and fine particles, etc., ensuring the quality of the circulating water.

[0037] The water after filtration and purification is re-extracted by the transfer pump 611 and transported to the spray head 402 through the second transfer pipe, forming a closed water circulation system; such a design not only saves a large amount of water resources, but also reduces the equipment operation cost, meeting the requirements of modern environmental protection concepts.

[0038] Embodiment 2:

[0039] Two groups of second conveyor rollers 501 are arranged in the drying box 1, which are responsible for supporting and guiding the fire hose through the entire drying area; in order to ensure that the fire hose can maintain appropriate tension and flatness during the drying process, the second conveyor rollers 501 are driven by a servo motor, so that the fire hose can be smoothly transferred from one roller to another.

[0040] The drying air jets 502 located on the upper and lower sides inside the drying box 1 are the key components to achieve efficient drying; the drying air jets 502 are interconnected to ensure that the hot air can cover all surfaces of the fire hose; each drying air jet 502 is equipped with multiple small holes for spraying the heated air flow, thereby forming a dense hot air curtain, which not only speeds up the water evaporation rate, but also avoids the risk of material damage caused by local overheating.

[0041] The air heating box 504 is internally provided with an electric heater 505, which can heat the incoming air to a set temperature, usually between 60°C and 80°C. This temperature range can not only ensure rapid drying, but also will not damage the fire hose; the fan 506 is installed in the drying chamber 503, and its function is to extract the heated air and send it into the drying air jets 502 through the first air pipe; in addition, a second air pipe is fixedly installed on the left side of the fan 506, which is connected to one of the drying air jets 502, forming a complete air flow circulation path.

[0042] Embodiment three:

[0043] The design of connecting the first conveying roller 401, the sponge cleaning brush roller 403 and the second conveying roller 501 to the servo motors installed on the back of the drying box 1 and the cleaning box 2 respectively is as follows:

[0044] The first conveying roller 401 and the sponge cleaning brush roller 403 are located inside the cleaning box 2, and they are connected to the servo motor installed on the back of the cleaning box 2 through a coupling; this connection method ensures that each roller can rotate under precise control, which can not only provide the necessary traction to allow the fire hose to pass through the cleaning area smoothly, but also stop rotating when necessary for maintenance or troubleshooting.

[0045] The second conveying roller 501 is also connected to the servo motor installed at the back of the drying box 1 through a similar transmission mechanism.

[0046] In summary, the water circulation type fire hose automatic cleaning and drying equipment realizes efficient recycling of water resources through the water purification circulation structure 6; specifically, the connecting pipe 601 at the bottom of the cleaning box 2 guides the used water into the mixing tank 606 inside the equipment box 3; at the same time, the flocculant box 603 adds flocculant to the mixing tank 606 in a quantitative manner through the feeding pipe 604, and the driving motor 608 drives the stirring rod 607 to fully mix the water and the flocculant to promote the coagulation of impurities; then, the sewage enters the filter tank 609, and is filtered and purified at multiple levels through the filter cartridge 610 composed of a sponge filter inner layer 6101, a glass fiber middle layer 6102 and an activated carbon outer layer 6103; finally, the delivery pump 611 pumps the purified water back to the sprinkler head 402, thereby realizing the recycling of water, reducing the consumption of fresh water sources, and reducing operating costs and environmental impacts.

[0047] In addition, the water-circulating fire hose automatic cleaning and drying equipment, the drying structure 5 ensures that the fire hose is dried quickly and evenly; two sets of second conveyor rollers 501 support the fire hose to pass through the drying box 1, during which the drying jet pipe 502 sprays hot air to the fire hose from top and bottom; the electric heater 505 in the air heating box 504 heats the air, and the fan 506 draws the heated air through the first air pipe and blows it to the fire hose through the connected drying jet pipe 502, thereby realizing the simultaneous cleaning and drying of the fire hose, improving the overall work efficiency, and solving the problem that the existing technology does not fully take into account the recycling of water resources. Each complete cleaning cycle consumes a large amount of fresh water, which is unfavorable for long-term cost control and environmental protection.
