Description

Technical Field

[0001] The utility model relates to the field of garbage disposal, in particular to a screening mechanism for kitchen waste. Background Art

[0002] Kitchen waste is a type of organic waste. Because it contains high levels of water and organic matter, it is very easy to rot, so it must be professionally processed and treated to be converted into new resources, such as fertilizer, feed, etc. In addition, it can also be used as biogas fuel or for power generation. Some waste containing oil and fat can be used to prepare biofuels.

[0003] When processing food waste, a drum screen is needed to separate recyclable and non-recyclable materials.

[0004] While using a conveyor belt to transport food waste to the drum screen, the oil and sewage in the food waste will fall between the conveyor belt and the driving wheel, causing the driving wheel and the belt to slip, thus affecting transportation. Utility Model Content

[0005] The utility model aims to provide a screening mechanism for kitchen waste, which has the advantage of reducing the amount of sewage and oil in the kitchen waste falling between the belt and the driving wheel of the conveyor belt during the transportation of the kitchen waste.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A screening mechanism for kitchen waste comprises a support seat, a drum screen, and a conveyor belt, wherein the drum screen is fixedly connected to the upper part of the support seat, the drum screen comprises an inner screen and a shell, the inner screen is rotatably connected to the inside of the shell, a discharge port is provided at the bottom of the shell, and a conveyor belt is provided below and at both ends of the drum screen, characterized in that a plurality of rows of support frames are fixedly connected below the shell, a water collecting trough is provided above the support frame, the water collecting trough is slidably connected to the support frame, a sieve plate is fixedly connected to the upper opening of the water collecting trough, a cylinder is fixedly connected to the side of the outer wall of the shell, the cylinder output shaft is fixedly connected to the water collecting trough, an opening is provided at the upper part of the water collecting trough, and the water collecting trough opening is located directly below the discharge port at the bottom of the shell.

[0008] By adopting the above technical solution, the rotation of the drum screen causes the kitchen waste on the screen surface to flip and roll, and small garbage falls out from the screen holes. At the same time, the sewage and oil in the kitchen waste are thrown out and enter between the inner screen and the shell, and then fall into the screen plate of the sump, and the liquid matter falls into the sump. After screening for a period of time, the cylinder moves the sump, and the lower discharge port of the drum screen opens, and the solid waste under the screen falls onto the conveyor belt below, reducing the liquid matter falling onto the conveyor belt and affecting its transportation of garbage.

[0009] Preferably, the contact surface between the belt and the driving wheel of the conveyor belt is provided with gear teeth, and the belt and the driving wheel are meshed through the gear teeth.

[0010] By adopting the above technical solution, the gear teeth increase the friction between the driving wheel and the belt.

[0011] Preferably, the inner wall of the inner screen is fixedly connected with threads.

[0012] By adopting the above technical solution, the garbage in the drum screen can be better transported.

[0013] Preferably, a sawtooth block is fixedly connected to the inner wall of the inner screen.

[0014] By adopting the above technical solution, bags can be broken and garbage can be screened better.

[0015] Preferably, a brush is fixedly connected to the inner wall of the shell, and the brush is in contact with the inner screen.

[0016] By adopting the above technical solution, the inner screen rotates and the brush can clean the inner screen to prevent the screen holes from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0023] See also Figure 1 -- Figure 4A screening mechanism for kitchen waste comprises a support seat 1, a drum screen, and a conveyor belt 2. The drum screen is fixedly connected to the upper part of the support seat 1. The drum screen comprises an inner screen 3 and a shell 4. The inner screen 3 is rotatably connected to the inside of the shell 4.
