Description

Technical Field

[0001] The utility model relates to the technical field related to sludge treatment, in particular to a water recycling system for a vehicle-mounted sludge solidification device. Background Art

[0002] The operation of sewage treatment plants usually produces a large amount of sludge. If the sludge is not properly treated, it will have a serious impact on the environment. Therefore, a sludge solidification device is needed for treatment. However, the existing sludge solidification device still has certain defects when used;

[0003] During use, the existing sludge solidification process is to add a solidifying agent to the dewatered sludge to form a solidified body with good integrity. However, after filtering out the sludge, it needs to be manually stirred, which has a poor stirring effect, increases the labor intensity of the staff, and cannot meet the needs of modern production.

[0004] In order to overcome the above-mentioned defects, prior art 1 (Chinese patent application number 201922498478.2, application date 2019-12-31) is a solidification device utilizing sludge slag resources, comprising a frame, a feed port, a pusher box, a mixing box and a solidification box, wherein the pusher box is mounted on the frame, the feed port is mounted on the pusher box, the pusher box is provided with a sludge channel, the pusher box is provided with a pusher device, the mixing box is provided with a mixing device, the mixing device is provided with a filter plate, the filter plate is provided with a purification tank, the mixing box is provided with a dosing device, the mixing box body is provided with a control component, and the solidification box is provided with an extrusion device, thereby realizing an automated stirring method, improving the solidification effect of the sludge, and having a reasonable overall structural design;

[0005] Although the existing technology can realize an automated stirring method, during the working process, the sludge is processed and solidified through a push box, a mixing box and a solidification box. Not only does the whole process require clean water for auxiliary operations during solidification, but it also requires cleaning operations after solidification, which results in a large amount of water resource usage, increases the overall cost, increases the pressure on water resource management, and produces more polluted water, which affects the external environment.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original vehicle-mounted sludge solidification device water recycling system. Therefore, we proposed a vehicle-mounted sludge solidification device water recycling system that can well solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a vehicle-mounted sludge solidification device water recycling system to solve the problem raised in the above-mentioned background technology that the sludge in the current market is processed and solidified as a whole through a pushing box, a mixing box and a solidification box. Not only does the whole need clean water for auxiliary operation during solidification, but also cleaning operations are required after solidification, which results in a large amount of water resource usage, increases the overall cost, increases the pressure on water resource management, and produces more polluted water, resulting in the problem of affecting the external environment.

[0008] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a vehicle-mounted sludge solidification device water recycling system, comprising a vehicle seat;

[0009] A mud mixing box is provided on the vehicle seat, which is connected to a medicine mixing box through a medicine pump, which is connected to a filter press through a mud double-cylinder plunger pump. The filter press is installed on the vehicle seat, and clean water enters the mud mixing box from the medicine mixing box and is then pumped into the filter press. The liquid after filtration flows back into the medicine mixing box.

[0010] Preferably, a pretreatment component is provided at the upper end of the mud mixing box, and the pretreatment component includes a rotary screen machine installed on the mud mixing box.

[0011] Preferably, the rotary screen machine is connected to a screen body, the screen body is located inside the mud mixing box, and a guide plate is provided at the bottom of the rotary screen machine.

[0012] Preferably, the mud mixing box is provided with a first mixer away from the pretreatment component, and an electric control box is installed at the side end of the mud mixing box.

[0013] Preferably, a generator is installed at the side end of the electric control box, and the generator is installed on the vehicle seat.

[0014] Preferably, a feed pump is installed on the vehicle seat, and a delivery end of the feed pump is connected to the mud mixing box near the pretreatment component.

[0015] Preferably, a second mixer is installed on the medicine mixing box, a conveyor is provided at the bottom of the filter press, and an adjustable filter plate is provided on the conveyor.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: in the vehicle-mounted sludge solidification device water recycling system, clean water enters the mud mixing tank from the chemical mixing tank and is then pumped into the filter press. The liquid after filtration flows back into the chemical mixing tank, thereby reducing the discharge of sewage and the problem of polluting water resources and affecting the surrounding environment. In addition, the overall water resources are circulated and no external water is required. This not only reduces the overall cost but also alleviates the pressure of overall management. The specific contents are as follows:

[0017] Clean water enters the slurry mixing tank from the reagent mixing tank, and is then pumped into the filter press. The liquid after filtration flows back into the reagent mixing tank, and the entire water resource is circulated. No external water is required, which reduces the problem of polluting water resources and affecting the surrounding environment.

[0018] The electric control box monitors the equipment status in real time to ensure efficient operation. An appropriate amount of PAM flocculant is added to the reagent mixing tank and stirred evenly using the second mixer. The adsorption and bridging effects of the PAM flocculant aggregate fine solid particles into larger particles, making it easier to process them later.

[0019] The sewage is treated by the rotary screen machine of the pretreatment component. The guide plate of the rotary screen machine guides the particles out, and the remaining mud enters the mixing side of the mud mixing tank, reducing the problem of large particles inside the mud wearing the first mixer and shortening its service life.

[0020] Start the mud double-cylinder plunger pump. The mud double-cylinder plunger pump is equipped with a lower limit stop function to prevent damage due to vacuum. After stopping, it needs to be manually started, which greatly improves the overall operational safety, thereby reducing the wear problem caused by automatic start and extending the overall service life;

[0021] The set conveyor pulls the filter plate apart and transports the unloaded filter cake. During the unloading process, it is necessary to manually shake the filter cloth or use a mud shovel to clean the material stuck on the filter cloth, which improves the smoothness of the overall operation, facilitates reuse and operation, and improves the overall practicality.
