Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste treatment, and in particular to a crushing device for kitchen waste treatment. Background Technology

[0002] Food waste refers to food scraps, waste oil, and expired food generated during food processing, catering services, and dining in establishments such as hotels, restaurants, enterprise and institution canteens, and school canteens. Food waste contains a large number of pathogens that can cause zoonotic infectious diseases, which can easily lead to cross-infection of viruses in animals and also cause human infections such as foot-and-mouth disease and hepatitis.

[0003] Extensive searching revealed Chinese Patent Publication No. CN211392777U, which discloses a recyclable waste screw conveyor for a waste station. The device includes a main body, a support frame fixedly connected to the bottom of the main body, a movable cover movably connected to the side of the main body, a handle movably connected to the outer side of the movable cover, a feed hopper fixedly connected to the top left side of the main body, and a discharge port on the bottom right side of the main body. This application provides a recyclable waste screw conveyor for waste stations. The movable cover on the surface of the main body facilitates easy opening and maintenance of the internal components. The rotation of a motor drives a crushing rod, which agitates the recyclable waste in the feed hopper, preventing blockage and improving efficiency. The crushing rod also crushes the recyclable waste while agitating it, reducing subsequent processing steps and increasing efficiency.

[0004] In summary, existing screw conveyor systems cannot handle liquid waste, which may contain a large amount of liquid.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a crushing device for food waste treatment, which would make it more industrially valuable. Utility Model Content

A feeding base is installed in the crushing box below the material discharge chamber. A spiral conveying assembly distributed in the left and right direction is provided on the feeding base. The feeding motor outside the crushing box on the right side of the spiral conveying assembly is connected to the spiral conveying assembly on the inner side. A discharge port is installed on the crushing box on the right side of the spiral conveying assembly. The discharge port is adapted to the conveying unit on the lower right side.

[0011] Several drainage holes are evenly distributed on the feeding base. The bottom left side of the crushing box is connected to the water collection tank below through the water inlet. The water outlet is installed on the bottom left side of the water collection tank.

[0012] As a further improvement of this utility model, the conveying unit includes a first conveying platform that moves along the front-to-back direction and a second conveying platform that moves along the left-to-right direction.

[0013] As a further improvement of this utility model, the first conveying platform moves along the front-to-back direction on the first conveying track below, and the second conveying platform moves along the left-to-right direction on the second conveying track below.

[0014] As a further improvement of this utility model, a connecting port that connects to the front, back, left, and right sides is provided at the intersection of the first and second conveying tracks.

[0015] As a further improvement of this utility model, a filter screen is installed on the feeding base above or below the drain hole.

[0016] As a further improvement of this utility model, both the feeding base and the screw conveyor assembly are arranged with an inclined structure that is lower on the left and higher on the right.

[0017] As a further improvement of this utility model, a visible observation window is provided on the crushing box body on one side of the crushing roller assembly and the screw conveyor assembly.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] This invention can crush kitchen waste and collect liquid waste that leaks into the water collection tank below during the transportation process, while solid waste is transported out via a screw conveyor assembly.
