Description

Food waste crushing and sorting machine

technical field

The invention relates to the technical field of solid waste food waste pretreatment, in particular to a food waste crushing and sorting machine.

Background technique

Anaerobic fermentation biogas recycling process is the mainstream development trend of domestic kitchen waste disposal. The difficulty of this process is wet pretreatment and solid fermentation process. The prerequisite for the successful operation of the solid fermentation system is that the pretreatment is stable and efficient. running.

Food waste is generally processed through crushing, sand removal, and oil separation, and then anaerobic fermentation can be used for power generation and biodiesel production. Due to factors such as my country's eating habits, garbage classification, and weak awareness of resource recycling, there are more impurities in food waste, high water content, mixed with a large amount of plastic, disposable packaging, tableware, and even some domestic waste, construction materials, etc. Garbage will also be mixed in. Therefore, the crushing of kitchen waste requires a special crushing device. After the food waste is recycled, it undergoes crushing and beating treatment, and the organic matter is crushed to obtain a slurry after the food waste is crushed, which provides a guarantee for the stable operation of the subsequent anaerobic process. During the crushing process, the hard-to-break and other inorganic substances in the food waste can also be removed to avoid the formation of a scum layer in the anaerobic tank. In the prior art, most of the kitchen crushing and sorting machines are horizontal, occupying a large area, low processing efficiency, heavy equipment itself, and inconvenient installation and maintenance.

Processing device.

The technical scheme of invention is realized like this:

Food waste crushing and sorting machine, the sorting machine includes a circular connecting frame, and a circular filter screen is set inside the filter screen connecting frame. There are water inlet holes; the filter screen is equipped with a rotating main shaft, and the rotating main shaft is equipped with striking blades; the upper and lower parts of the rotating main shaft are respectively fixed by the bearing seat on the machine cover and the base, and the rotating main shaft is connected with the driving device through a coupling ; The filter screen and the lower seat form a chamber 1 for solid-liquid separation of domestic waste; a chamber 2 for collecting paddle liquid is formed between the lower seat and the base; the slurry outlet is installed at the bottom of the base; The frame is arranged on the rotating main shaft in the second cavity; the feed inlet extends to the filter sieve cylinder through the connecting frame; the outlet of inorganic substances is installed on the upper end of the connecting frame.

Further, the striking blades are arranged in a helical shape on the rotating main shaft, and the inclination angle between adjacent striking blades is 60°.

Further, the position of the above-mentioned water inlet hole is in a spiral shape.

Further, the above-mentioned feeding port is provided at the bottom of the filter screen.

Further, a sealing observation door is installed around the outside of the connecting frame.

Compared with the existing food waste crushing and sorting machine, the present invention has the advantages of compact structure, stable operation, high working efficiency, convenient installation and maintenance, and the like.

detailed description

Further explanation is made below in conjunction with accompanying drawing:

The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in the figure, the food waste crushing and sorting machine is mainly composed of motor 1, water supply system 2, striking blade 3, rotating main shaft 4, filter sieve cylinder 5, connecting frame 6, lower seat 7, feeding frame 8, feeding Mouth 9, inorganic substance outlet 10, slurry outlet 11, base 12 form.

The water supply system 2 is composed of steel pipes, hoses, valves, etc., and the water volume can be adjusted.

The striking blades 3 are arranged in a helical shape on the rotating main shaft 4, and the inclination angle between adjacent striking blades 3 is about 60°. The striking blades 3 are detachable for easy maintenance.

The bearing seats of the upper cover top and the lower base of the rotating main shaft 4 are fixed, and the upper part is connected with the motor 1 through a shaft coupling.

Connecting frame 6 is circular, is equipped with observation (maintenance) hole all around, detachable.

The filter screen cylinder 5 is circular and installed in the connecting frame 6. The diameter is smaller than the diameter of the connecting frame. The aperture of the screen cylinder (aperture 6mm) and the same spacing are evenly distributed. Water inlet holes are arranged around the screen cylinder. The position is spiral.

The feed inlet 9 extends to the filter screen cylinder 5 through the connecting frame 6, and the feed inlet 9 can be square, circular or other shapes.

Rotating main shaft 4 tops connect motor 1, and the center is helically installed detachable striking blade 3, and the lower end installs material shifting rack 8, and the bottom end is connected with the bearing seat on the base 12. The rotating main shaft 4 is placed in the filter screen cylinder 5 with water inlet pipes installed around it, the filter screen cylinder 5 is fixed inside the connecting frame 6, and a sealed observation door is installed around the outside of the connecting frame 6, and the motor 1 and the water supply system 2 are installed on the upper part. The bottom is connected with the lower seat 7 installed on the base 12 . The feed inlet 9 of the food waste crushing and sorting machine is installed at the bottom of the filter sieve drum 5 , the outlet of inorganic matter 10 is installed at the top of the connecting frame 6 , and the slurry outlet 11 is installed at the bottom of the base 12 .

The food waste enters the filter screen cylinder from the feed port. When the motor drives the rotating shaft to rotate at a high speed, the striking blades distributed in a spiral structure on the rotating shaft are rotated at a high speed, and the speed reaches 1200r/min. The violent collision breaks the food waste; at the same time, the water supply system starts to work, and the water volume is adjusted to an appropriate range for spraying, which can clean the grease attached to the inorganic matter of the food waste; under the high-speed rotation of the motor, strong The centrifugal force of the crushed garbage slurry is thrown onto the filter screen cylinder with an aperture of 6mm. The slurry passing through the mesh of the filter cylinder is sprayed by the water supply system and enters the inner side of the connecting frame, flows into the lower seat, and passes through the material rack. The blades transfer the slurry to the slurry outlet and enter the next process for subsequent processing; the inorganic substances (such as plastics, disposable packaging, etc.) in the crushed food waste materials and the materials larger than 6mm are separated by centrifugal force. Rise up and discharge from the inorganic substance outlet on the upper part of the connecting frame. The device of the invention effectively sorts the useful organic matter and inorganic matter in the kitchen waste to obtain the slurry with ideal water content.

The device of the invention can realize the advantages of thorough solid-liquid separation of kitchen waste, homogeneous slurry, high efficiency, compact structure, convenient installation and maintenance, and the like.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of changes or modifications within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention.
