Description

Technical Field

[0001] This utility model belongs to the field of environmental protection equipment technology and relates to a hand-cranked activated carbon cleaning device. Background Technology

[0002] Currently, activated carbon has numerous applications in the market, such as water treatment, air purification, and industrial production. Activated carbon cannot be used directly upon receipt because its surface is covered with dust, carbon powder, and other impurities. Therefore, it must be cleaned before use. Failure to clean it can cause serious pollution to the environment and water bodies, and may also cause irreversible damage to some machinery.

[0003] Although some industries (such as water treatment) cannot do without activated carbon, the required quantity is not large, making it difficult to form a large-scale, standardized, fully automated cleaning method. Therefore, most cleaning methods are manual cleaning.

[0004] However, manual cleaning has obvious drawbacks: it is inefficient and wastes resources and effort. Manual cleaning typically only removes impurities from the surface of activated carbon, failing to thoroughly remove pollutants from within the pores, resulting in limited adsorption capacity. During the cleaning process, especially vigorous scrubbing or using hard brushes, the pore structure of the activated carbon may be damaged, reducing its adsorption performance. Manual cleaning may also result in incomplete cleaning of some areas, affecting the overall performance of the activated carbon. Manual cleaning is also less effective at removing certain chemically adsorbed pollutants (such as heavy metals and organic matter). Furthermore, if the water or tools used for cleaning are not clean, new pollutants may be introduced, leading to secondary pollution. Moreover, manual cleaning requires a significant amount of time and physical effort and is inefficient. Summary of the Invention

[0005] The technical problem solved by this utility model is to provide a hand-cranked activated carbon cleaning device, which combines stirring and spraying head driven by a hand crank to achieve efficient cleaning, water saving and environmental protection, and reduce the complexity of operation.

[0006] This utility model is achieved through the following technical solution:

[0007] A hand-cranked activated carbon cleaning device includes a cleaning cover mounted between fixed supports via a horizontal shaft. Both ends of the cleaning cover are sealed with support panels. The outer cover between the support panels is evenly distributed with mesh and has a feed port. Both ends of the horizontal shaft extend out of the support panels and are mounted on the fixed supports. One end of the horizontal shaft is connected to a hand crank. The horizontal shaft is also fixedly connected to the support panels.

[0008] A water pipe support is also provided on the side of the fixed bracket. The water pipe is horizontally mounted on the water pipe support and located above the cleaning hood. Multiple nozzles are arranged on the water pipe.

[0009] The cleaning hood is cylindrical, and the mesh is arranged in an array on the cleaning hood.

[0010] The cleaning hood is made of metal mesh rolled into a cylindrical shape.

[0011] The fixed end of the feed inlet is connected to the cleaning hood by bolts or hinges, and the movable end is movably connected to the cleaning hood by a buckle.

[0012] The horizontal axis is welded to the support panel, and multiple auxiliary support ribs are provided between the horizontal axis and the cleaning hood.

[0013] The fixed bracket is a Y-shaped bracket, with a bearing seat at the top center; one end of the horizontal shaft is fitted into the bearing seat, and the other end extends out of the bearing seat and connects to the hand crank.

[0014] The end of the horizontal shaft is connected to the hand crank via a detachable cross buckle.

[0015] The water pipe support is a Y-shaped support, which is set on the side of the fixed support; the water pipe support is equipped with a tripod to support the water pipe.

[0016] The water pipe is connected to a faucet or water pump.

[0017] Furthermore, it is also equipped with multiple soaking containers.

[0018] Specifically, the cleaning hood is a cylinder with a length of 1 to 1.5 meters and a diameter of 0.8 to 1 meter, with a mesh of 1 to 1.5 cm × 1 to 1.5 cm on the outer cover; or the mesh is a round hole with a diameter of 2 to 3 cm.

[0019] The feed inlet is an opening that is 80-100cm long and 30-40cm wide;

[0020] The nozzles are evenly distributed at intervals of 8-10cm, and the spray range of the nozzles covers the cleaning hood.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] This invention provides a hand-cranked activated carbon cleaning device that uses a cleaning mesh cover, a manual stirring mechanism, and a spray nozzle in combination to clean activated carbon. Rotating the hand crank causes the cleaning mesh cover to rotate, resulting in the activated carbon tumbling and being physically rinsed by flowing water. The mesh cover then filters out contaminants from the activated carbon. This device is simple in structure, low in cost, and suitable for activated carbon cleaning needs in environments without electricity or in small-scale settings, as well as for cleaning small-scale (1-20 kg) activated carbon in laboratories.

[0023] This invention is suitable for small-scale cleaning and can be used without power without affecting work efficiency. The device is also detachable and portable, making it suitable for different scenarios.

[0024] This invention can prevent secondary pollution from activated carbon and avoid secondary pollution caused by workers directly contacting activated carbon; it also saves costs, as the use of automatic spray nozzles can significantly reduce water output and avoid water waste; it requires no electricity and is suitable for field operations or areas with unstable power supply.

[0025] This invention can improve cleaning efficiency and shorten the cleaning time compared to traditional manual cleaning; it has low maintenance costs, a simple structure, and is easy to disassemble and replace parts; it also allows for monitoring of the cleaning progress at any time, avoiding over-cleaning that could lead to activated carbon loss.
