Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to an air washing device for an inclined screen type solid-liquid separator. Background Art

[0002] Large-scale breeding is prone to breed many pathogens. In line with the principle of epidemic prevention and sanitation, the breeding farm should be located more than 1 km away from residents or towns, with high terrain, open and flat. During breeding, a lot of breeding manure will be produced. The breeding manure contains a lot of water, which needs to be separated from the solid and liquid before subsequent environmental protection treatment. Inclined screen solid-liquid separators are widely used in farms to separate the solid and liquid of breeding manure, and their separation effect is high.

[0003] The inclined screen solid-liquid separator needs to be cleaned regularly during operation to prevent feces from blocking the screen and affecting work efficiency and results. At present, most of the existing inclined screen solid-liquid separators use water washing to clean the screen to ensure the normal operation of the solid-liquid separator, but a large amount of flushing water enters the back-end wastewater treatment system, which not only wastes water resources, but also increases the amount of wastewater treatment and treatment costs. In line with the principles of protecting the environment and saving water, it is obvious that this technology still has a lot of room for improvement.

[0004] Therefore, we need to design an air washing device for the inclined screen solid-liquid separator to solve the above problems. Utility Model Content

[0005] According to one aspect of the utility model, an air washing device for an inclined screen solid-liquid separator is provided, comprising an air knife, wherein both ends of the air knife are connected to sliders, wherein the sliders are slidably connected to a track provided on the inclined screen solid-liquid separator, wherein an inclined screen is installed in the inclined screen solid-liquid separator, wherein the air knife is located above the screen, wherein a driving motor is provided on the slider, wherein the driving motor drives the slider to move back and forth along the track, thereby driving the air knife to move back and forth above the screen. The utility model can blow high-pressure air onto the screen through the air knife located above the screen; under the action of the driving motor, the slider is moved back and forth along the track, thereby driving the air knife to move back and forth above the screen, thereby completing the cleaning of the screen. The air washing device can completely replace the traditional water washing method, thereby saving water, reducing the amount of wastewater treatment system processing increased due to water washing, and reducing the cost of wastewater treatment.

[0006] In some embodiments, the length of the wind knife is adapted to the width of the screen. The beneficial effect is that the effect and efficiency of screen cleaning can be guaranteed, so that the entire screen can be fully cleaned.

[0007] In some embodiments, the number of the wind knife is at least one. The beneficial effect is that the number of the wind knife can be one or more, and one or more wind knives can be opened according to the degree of dirtiness of the screen.

[0008] In some embodiments, there are two tracks, which are arranged in parallel on both sides of the inclined screen solid-liquid separator, and the tracks are located above the screen. The beneficial effect is that the two parallel tracks are used, which are distributed on both sides, so that the wind force of the wind knife is unobstructed, there is no dead angle, and the machine is evenly stressed, which has a good cleaning effect on the screen.

[0009] In some embodiments, the rail is made of stainless steel or hot-dip galvanized material. The beneficial effect is that stainless steel or hot-dip galvanized material is not easy to rust, is more resistant to corrosion, and has a long service life.

[0010] In some embodiments, a high-pressure blower is further included, and the high-pressure blower is connected to the wind knife through an air duct. The beneficial effect is that the high-pressure blower provides high-pressure wind to the wind knife through the air duct, and the high-pressure wind blows away the dirt on the screen, which can more effectively achieve the effect of cleaning the screen.

[0011] In certain embodiments, the high-pressure blower is installed on the ground next to the inclined screen solid-liquid separator.

[0012] In some embodiments, a controller is further included, and the high-pressure fan and the drive motor are both connected to the controller, and the controller is used to control the operation of the high-pressure fan and the drive motor. The beneficial effect is that the controller controls the operation of the high-pressure fan and the drive motor, making the device more operable and controllable, and the drive motor can be enabled and wind power can be used according to specific circumstances.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model can blow high-pressure air onto the screen through the air knife located above the screen; under the action of the driving motor, the slider moves back and forth along the track, thereby driving the air knife to move back and forth above the screen to complete the screen cleaning work. The air washing device can completely replace the traditional water washing method, saving water, reducing the wastewater treatment system processing volume increased by water washing, and reducing the wastewater treatment cost.
