Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to garbage leachate recycling equipment. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of urban garbage generated continues to increase. During the landfill or storage process, garbage produces a large amount of leachate. This liquid has complex composition, high concentration, and high toxicity. If not properly treated, it will cause serious pollution to the environment.

[0003] Currently, various filter devices are widely used to treat landfill leachate. However, existing landfill leachate filter devices have some obvious shortcomings. The most prominent problem is that most of these filter devices do not have a self-cleaning function for the filter screen.

[0004] During the leachate filtration process, the filter screen gradually becomes clogged with impurities, resulting in a decrease in filtration efficiency. To maintain proper operation, the filter screen must be frequently cleaned or replaced manually. This not only increases labor and equipment maintenance costs, but also requires the filtration system to be shut down during cleaning or replacement, affecting the continuous leachate treatment process and reducing treatment efficiency.

[0005] Furthermore, manual cleaning of filters often fails to completely remove clogs and can damage them, shortening their lifespan. Replacing filters requires time and resources, while also generating more waste.

[0006] Therefore, in order to solve the problems of easy clogging of the filter net and lack of self-cleaning function in the existing landfill leachate filtering device, a new type of landfill leachate recycling filtering device is urgently needed. Utility Model Content

[0007] In order to solve the above problems, the utility model designs a garbage leachate recycling device.

[0008] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0010] A top plate is provided on the top end wall of the cylinder, and a cleaning drive mechanism is provided on the top end wall of the top plate.

[0011] Furthermore, the cleaning drive mechanism includes a shell, a water inlet pipe is provided on the side wall of the shell, the upper and lower inner walls of the shell are rotatably connected to a rotating rod through a sealed bearing, the outer wall of the rotating rod is penetrated by a through hole communicating with the inner cavity, a motor is provided on the top wall of the shell, and the output end of the motor is fixedly connected to the top of the rotating rod through a coupling, the bottom end of the rotating rod extends into the cylinder and is provided with a cleaning mechanism.

[0012] Furthermore, the cleaning mechanism includes a connecting rod, brush plates are provided on the two end walls of the connecting rod, and the brush plates are placed on both sides of the outer wall of the filter cartridge, a round rod is provided on the bottom end wall of the connecting rod, and an inclined plate is provided on the outer wall of the round rod through a support rod, and a water spray hole is opened on the outer wall surface of the inclined plate.

[0013] Furthermore, the inclined plate, the support rod, the round rod, the connecting rod and the rotating rod are connected.

[0014] Furthermore, valves are provided on the outer walls of the liquid inlet pipe, liquid discharge pipe and sewage discharge pipe.

[0015] Furthermore, the outer wall of the filter cartridge is in a cone shape.

[0016] The beneficial effects of the utility model are:

[0017] The device has a self-cleaning function, which can promptly remove impurities on the filter screen during operation to avoid filter blockage. This allows the filter device to always maintain a good filtering state and continuously and stably filter the landfill leachate, thereby greatly improving the filtering efficiency.

[0018] The self-cleaning function eliminates the need for frequent manual cleaning and replacement of the filter screen, saving significant labor costs. Operators no longer need to spend significant time and energy maintaining the filter, allowing them to devote more resources to other important tasks, further improving overall work efficiency.

[0019] Compared with manual cleaning, the self-cleaning function can more gently and effectively remove impurities on the filter surface, reducing damage to the filter. At the same time, it avoids the cost of frequent filter replacement, extends the service life of the filter, and reduces equipment maintenance costs.

[0020] Stable filtration performance ensures the treatment effect of landfill leachate. By removing impurities in a timely manner, the self-cleaning filter device can always maintain a high filtration accuracy and effectively remove various pollutants in the landfill leachate, such as organic matter, heavy metals, suspended solids, etc., ensuring that the treated water quality meets environmental protection requirements.
