[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 6 , the present invention provides the following technical solutions: A pretreatment device for kitchen waste slurry includes a crushing tank 1. In the middle of the top end of the crushing tank 1, a first driving motor 2 is fixedly connected. The output shaft of the first driving motor 2 extends into the crushing tank 1 and is fixedly connected to the stirring shaft. Crushing blades 3 are installed on the surface of the stirring shaft. A feed pipe 4 is installed on one side of the top end of the crushing tank 1. A cleaning component 5 is installed in the crushing tank 1. A discharge pipe 6 is installed at the bottom end of the crushing tank 1. The discharge pipe 6 is connected to the top end of the extrusion pipe 7 in a communicating manner. One end of the extrusion pipe 7 is fixedly connected to a second driving motor 8. The output shaft of the second driving motor 8 extends into the extrusion pipe 7 and is connected to an auger 9. A filter plate 10 is installed at the bottom end of the auger 9 in the extrusion pipe 7. The other end of the extrusion pipe 7 is hinged with a sealing cover 11. Connecting blocks 12 are provided on the side surface of the sealing cover 11 and the side surface of the end of the extrusion pipe 7. When the sealing cover 11 and the extrusion pipe 7 are closed, the two connecting blocks 12 are aligned and fixed by bolts.

The end of the connecting rod 52 located outside is fixedly connected to a connecting handle 54. The annular scraper 51 fits the inner wall of the crushing tank 1.

[0024] Specifically, the staff member drives the connecting rod 52 to move downward through the connecting handle 54, so that the annular scraper 51 can scrape the slurry splashed and adhered to the inner wall of the crushing tank 1, facilitating the cleaning of the inside of the crushing tank 1.

[0025] In this embodiment, the filter plate 10 is arc-shaped, and hanging ears 13 are provided on both sides of the filter plate 10.

[0026] Specifically, the slurry falling into the extrusion tube 7 first lands on the surface of the filter plate 10, and then the slurry in the slurry can be filtered. The second drive motor 8 drives the auger 9 to rotate, so that the auger 9 can convey the slurry towards the sealing cover 11. When the slurry accumulates at the sealing cover 11 and the auger 9 continues to convey, the excess slurry in the slurry can be squeezed, and the squeezed slurry flows into the bottom of the extrusion tube 7 through the filter plate 10.

[0027] In this embodiment, an annular water pipe 15 is installed at the top end inside the crushing tank 1, a spray head 16 is installed at the bottom of the annular water pipe 15, a connecting pipe 17 communicating with the annular water pipe 15 is installed at the top end of the crushing tank 1, and the connecting pipe 17 is connected to an external water source.

[0028] Specifically, water is supplied into the annular water pipe 15 through the connecting pipe 17, and the water in the annular water pipe 15 is sprayed out through the spray head 16, facilitating the cleaning of the inside of the crushing tank 1, and disinfecting the inside of the crushing tank 1 when spraying disinfectant.

[0029] In this embodiment, a spiral blade 18 is installed at the bottom end of the stirring shaft.

[0030] Specifically, the spiral blade 18 can convey the slurry blocked at the bottom of the crushing tank 1 downward, so that the blocked slurry can enter the extrusion tube 7 through the discharge pipe 6, avoiding the influence of slurry blockage on the slurry treatment effect.

[0031] In this embodiment, a first limiting hole 55 is formed on the surface of the sleeve 53, a second limiting hole 56 is formed on the surface of the connecting rod 52, a limiting pin 57 is inserted and connected in the first limiting hole 55 and the second limiting hole 56, and when the first limiting hole 55 is aligned with the second limiting hole 56, the annular scraper 51 fits against the top end of the crushing tank 1.

[0032] Specifically, after lifting the connecting rod 52 downward to align the first limiting hole 55 with the second limiting hole 56, the position of the connecting rod 52 can be fixed by the limiting pin 57.

[0033] In this embodiment, a sealing groove 19 is provided at one end of the extrusion tube 7 at the end of the sealing cover 11. A sealing rubber ring 20 is provided on the side of the sealing cover 11, and the size of the sealing rubber ring 20 matches the size of the sealing groove 19.

[0034] Specifically, by setting the sealing rubber ring 20 in cooperation with the sealing groove 19, the sealing performance between the sealing cover 11 and the end of the extrusion tube 7 can be improved.

[0035] In this embodiment, a first wedge surface 21 is provided at the inner bottom of the crushing tank 1, a second wedge surface 22 is provided at the inner bottom end of the extrusion tube 7, and a collecting tube 23 is installed at the bottom end of the extrusion tube 7.

[0036] Specifically, by setting the first wedge surface 21, it is convenient for the crushed slurry to enter the extrusion tube 7 through the discharge pipe 6 as much as possible, and by setting the second wedge surface 22, the filtered slurry can be discharged through the collecting tube 23 as much as possible.

[0037] In this embodiment, a first leg 24 is fixedly connected between the crushing tank 1 and the extrusion tube 7, and a second leg 25 is installed at the bottom end of the extrusion tube 7.

[0038] Specifically, by setting the first leg 24, the stability of the use of the crushing tank 1 can be improved, and by setting the second leg 25, the stability of the use of the device can be improved.

[0039] Working principle: The slurry to be processed is put into the crushing tank 1 through the feed pipe 4. The crushing blade 3 is driven by the first driving motor 2 to initially crush the slurry. The crushed slurry falls into the extrusion tube 7 through the discharge pipe 6. By setting the spiral blade 18, the slurry can be prevented from being blocked at the discharge pipe 6. The second driving motor 8 drives the auger 9 to convey and extrude the slurry falling into the extrusion tube 7. The slurry generated by the extrusion is discharged through the collecting tube 23. The staff can open the sealing cover 11 to collect and process the extruded slurry. By setting the cleaning component 5, the inner wall of the crushing tank 1 can be cleaned. By setting the annular water pipe 15 in cooperation with the nozzle 16, the inside of the crushing tank 1 can be further cleaned.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
