[0018] Example: See Figures 1 to 3 As shown, a perishable garbage feeding device with preliminary sewage separation and filtration includes a hopper 1, a rectangular tubular discharge port 11 is formed at the lower end of the hopper 1, an inclined conveying pipe 2 is fixedly inserted into the discharge port 11, a feed slot 23 is formed on the pipe wall of the lower part of the conveying pipe 2, the feed slot 23 is located in the discharge port 11 of the hopper 1, the upper end of the conveying pipe 2 extends out of the discharge port 11 and is formed with a conical transition pipe 21, the upper end of the transition pipe 21 is formed with an inclined guide pipe 22, the upper wall of the guide pipe 22 is formed with a discharge slot 24, and a discharge pipe 6 connected to the discharge slot 24 is fixedly connected to the pipe wall of the guide pipe 22;

[0019] A central rotating shaft 3 is inserted into the conveying pipe 2, transition pipe 21 and guide pipe 22, and the lower end of the central rotating shaft 3 is pivotally connected to a cylindrical end cover 5, which is inserted and fixed to the lower end of the guide pipe 22, and an arc-shaped drainage groove 51 is formed on the outer wall of the lower side of the end cover 5; the upper end of the central rotating shaft 3 is fixed to the rotating shaft of the conveying motor 7, and the conveying motor 7 is fixed to the motor mounting plate 8, and the motor mounting plate 8 is fixed to the top of the guide pipe 22; a spiral conveying blade 4 is inserted and fixed on the central rotating shaft 3 between the end cover 5 and the motor mounting plate 8.

[0020] The central axis of the conveying pipe 2, the central axis of the transition pipe 21, the central axis of the guide pipe 22 and the central axis of the central rotating shaft 3 coincide with each other, otherwise the conveying blades 4 will interfere with the conveying pipe 2 during the rotation of the central axis 3; the inner diameter of the conveying pipe 2 is larger than the inner diameter of the guide pipe 22. Based on the reduction in the diameter, the garbage in the spiral conveying pipe is compressed, thereby achieving preliminary dehydration and preliminary separation of sewage and garbage.

[0021] The outer walls of the conveying pipe 2 are respectively against the inner walls on both sides opposite to the discharge port 11, the feed slot 23 is located on the upper wall of the conveying pipe 2, and the discharge slot 24 is located on the lower wall of the guide pipe 22. The discharge pipe 6 is vertical, and its discharge slot 24 is paired with the material hopper 1, and the discharge slot 24 is arranged on the lower wall of the guide pipe 22 to facilitate the output of garbage. A conveyor belt can be arranged under the discharge pipe 6 to transfer the garbage to the required processing equipment.

[0022] The conveying blade 4 is composed of a lower spiral blade with a cylindrical outer ring, a middle spiral blade with a conical outer ring and an upper spiral blade with a cylindrical outer ring. The lower spiral blade, the middle spiral blade and the upper spiral blade are respectively arranged in the conveying pipe 2, the transition pipe 21 and the guide pipe 22. The shape of the conveying blade 4 changes with the change of the conveying pipe 2.

[0023] The lower end of the delivery pipe 2 extends out of the discharge port 11 and is fixedly connected with a drainage pipe 10, which is convenient for connecting to a sewage pipe.

[0024] The central rotating shaft 3 is connected to the end cover 5 through a bearing. The upper and lower end faces of the end cover 5 are respectively against the upper limit sleeve 9 and the lower limit sleeve 20. The upper limit sleeve 9 and the lower limit sleeve 20 are respectively inserted and fixed on the central rotating shaft 3, that is, the central rotating shaft 3 and the end cover 5 are pivotally connected.

[0025] The lower end face of the end cover 5 is formed with a recessed platform 53, and the lower limit sleeve 20 is arranged in the recessed platform 53.

The outer wall of the upper limit sleeve 9 is formed with an extension arm 91, and the outer end of the extension arm 91 is formed with a shift rod 92. The shift rod 92 is inserted into the cleaning ring groove 52 of the end cover 5. Some small kitchen waste has the problem of blocking the drainage groove 51, and then a circular cleaning ring groove 52 is set at the entrance of the drainage groove 51. Based on the rotation of the central rotating shaft 3, the upper limit sleeve 9 is rotated, and then the shift rod 92 can move in the cleaning ring groove 52 to push away the small garbage blocking the entrance of the drainage groove 51.

[0026] Working principle: This structure is a perishable waste feeding device for preliminary separation and filtration of sewage. It is mainly the first process in the kitchen waste treatment line, that is, the feeding and conveying of kitchen waste. Its hopper 1 can hold the dumped kitchen waste, and the kitchen waste in the hopper 1 is output through the spiral conveying equipment;

[0027] However, this spiral conveying equipment adopts a conveying pipe 2 and a guide pipe 22 structure with a variable diameter structure. It compresses the kitchen waste in the spiral conveying equipment by narrowing the conveying channel, and realizes preliminary dehydration treatment. The sewage flows down along the inner pipe wall of the guide pipe 22, the transition pipe 21 and the conveying pipe 2, and is then discharged through the drainage trough 51, thereby realizing preliminary filtration and separation of kitchen waste and sewage during the conveying process.

[0028] The embodiments are intended to illustrate the present invention and are not intended to limit the present invention. Any person skilled in the art may modify the embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
