Description

Technical Field

[0001] The utility model relates to the field of kitchen waste fermentation devices, and particularly to a kitchen waste fermenter. Background Art

[0002] Kitchen waste refers to the waste generated in residents' daily life, food processing, food service, unit meal supply and other activities, including discarded vegetable leaves, leftovers, rice, fruit peels, eggshells, tea dregs, bones, etc. Kitchen waste is quite useful and can be made into fertilizers or feeds after being crushed and fermented. When the existing small fermentation containers ferment kitchen waste, since the fermented materials are relatively viscous, it is rather troublesome to clean the inside, and it is difficult to clean them thoroughly by flushing with water. Content of the Utility Model

[0003] The purpose of the utility model is to provide a kitchen waste fermenter to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A kitchen waste fermenter includes a fermentation barrel and a barrel cover. The barrel cover is arranged on the top of the fermentation barrel. A bearing hole is opened at the center of the barrel cover. A stirring bearing is installed in the bearing hole. A stirring shaft is rotatably installed in the stirring bearing. The bottom end of the stirring shaft extends into the fermentation barrel and is provided with a stirring roller. A stirring scraping wall motor is supported and installed on the top of the barrel cover. A driving gear is connected and installed on the stirring scraping wall motor. The driving gear is meshed with a driven gear. The top end of the stirring shaft extends above the barrel cover and is connected with the driven gear. A scraping part connecting rod is rotatably installed on the stirring shaft in the fermentation barrel through a one-way bearing. The end of the scraping part connecting rod is connected and installed with a barrel scraping part. The barrel scraping part is pressed against the inner barrel wall of the fermentation barrel. The barrel scraping part is composed of a cylindrical arc scraping part and an inclined scraping edge arranged on the inner arc surface of the cylindrical arc scraping part. A controller is installed on the outer side of the fermentation barrel.

[0006] Further, a discharge hole is opened at the bottom of the side barrel wall of the fermentation barrel. A discharge pipe is installed on the discharge hole. A discharge valve is installed on the discharge pipe.

[0007] Further, a motor gear cover is fixedly covered on the top of the barrel cover. The stirring scraping wall motor, the driving gear and the driven gear are all covered in the motor gear cover.

[0008] Further, a liquid hole and an air hole are opened on the barrel cover. An air valve is installed on the top of the air hole. A liquid pipe is installed on the top of the liquid hole.

[0009] Further, the fermentation barrel and the barrel cover are buckled and installed together through a cover locking fastener.

[0010] The beneficial effects are as follows: The kitchen waste fermenter described in the utility model can stir and ferment the kitchen waste in the barrel, with uniform fermentation and high efficiency. At the same time, reverse rotation is adopted to scrape the barrel, avoiding the adhesion of viscous substances generated during long-term fermentation to the inner wall, which is convenient for cleaning.

[0015] The present utility model will be further described below with reference to the drawings:

[0016] As Figure 1 - Figure 2 shown, a kitchen waste fermenter is composed of a fermentation barrel 1 and a barrel cover 2;

[0017] The barrel cover 2 is covered on the top of the fermentation barrel 1. A bearing hole is provided at the center of the barrel cover 2. A stirring bearing 3 is installed in the bearing hole. A stirring shaft 22 is rotatably installed in the stirring bearing 3. The bottom end of the stirring shaft 22 extends into the fermentation barrel 1 and is provided with a stirring roller 17. A stirring and scraping wall motor is supported and installed on the top of the barrel cover 2. A driving gear 11 is connected and installed on the stirring and scraping wall motor 10. The driving gear 11 is meshed and connected with a driven gear 12. The top end of the stirring shaft 22 extends above the barrel cover 2 and is connected with the driven gear 12;

[0018] A scraper connecting rod 5 is rotatably installed on the stirring shaft 22 in the fermentation barrel 2 through a one-way bearing 4. The end of the scraper connecting rod 5 is connected and installed with a barrel scraper 6. The fermentation barrel 1 is cylindrical. The barrel scraper 6 is pressed against the inner cylindrical wall of the fermentation barrel 1, which is convenient for scraping the inner wall;

[0019] The barrel scraping member 6 is composed of a cylindrical arc scraping member 20 and an inclined scraping blade 21 arranged on the inner arc surface of the cylindrical arc scraping member 20. The cylindrical arc scraping member 20 is pressed against the inner wall of the fermentation barrel 1, and the inner wall is scraped by the inclined scraping blade 21. A controller 7 is installed on the outer side of the fermentation barrel 1.

[0020] As Figure 1 - Figure 2 shown, the present utility model also discloses the following various more optimized specific structures:

[0021] A discharge hole is provided at the bottom of the side barrel wall of the fermentation barrel 1 to facilitate the discharge of the fermented food waste. A discharge pipe 18 is installed on the discharge hole, and a discharge valve 19 is installed on the discharge pipe 18.

[0022] A motor gear cover 9 is fixedly covered on the top of the barrel cover 2. The stirring and scraping wall motor 10, the driving gear 11 and the driven gear 12 are all covered in the motor gear cover 9.

[0023] A liquid hole 13 and an air hole 16 are provided on the barrel cover 2. An air valve 15 is installed at the top of the air hole 16, and a liquid pipe 14 is installed at the top of the liquid hole 13. A pipe cap is installed on the liquid pipe 14. The liquid pipe 14 is mainly convenient for supplementing the fermentation liquid.

[0024] The fermentation barrel 1 and the barrel cover 2 are fastened and installed together through a cover locking fastener 8.

[0025] As Figure 1 - Figure 2 shown, when the food waste fermenter shown is fermenting, the shredded food waste can be stirred. Specifically, by starting the stirring and scraping wall motor 10 to rotate forward, during the rotation, the stirring shaft 22 drives the stirring roller 17 to rotate, so as to stir and ferment the food waste fermentation material. When it is necessary to scrape the inner barrel wall of the fermentation barrel 1, the stirring and scraping wall motor 10 is rotated in the reverse direction, so that the stirring shaft 22 rotates in the reverse direction. Due to the action of the one-way bearing 4, it can drive the scraping member connecting rod 5 to rotate together, so as to drive the barrel scraping member 6 to scrape the inner barrel wall, avoiding the sticky kitchen waste fermentation product from accumulating on the inner barrel wall for a long time and being difficult to clean.
