All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0024] Combined with Figure 1 and Figure 2 , an anaerobic fermentation tank shell-breaking device includes a tank body 1 and a tank cover 2 threadedly connected to the upper surface of the tank body 1. A shell-breaking assembly 3 for preventing caking is provided inside the tank body 1, and a collection assembly 4 for collecting floating slag is provided inside the tank body 1.

[0025] The present utility model will be further described below in conjunction with the embodiments.

[0026] Embodiment 1:

[0027] Please refer to Figures 1-5 , the collection component 4 includes a limiting ring 41 fixedly installed on the inner wall of the tank body 1, and a collection box 42 placed on the upper surface of the limiting ring 41. A groove 43 is formed on the upper surface of the collection box 42. A spring 44 is arranged on the inner wall of the groove 43. The upper end of the spring 44 is fixedly installed with a connecting rod 45. The upper end of the connecting rod 45 is provided with an elastic block 46. The upper surface of the elastic block 46 is in contact with the bottom of the tank cover 2. A handle 47 is arranged on the upper surface of the collection box 42. A filter hole 48 is formed at the bottom of the collection box 42. The collection box 42 is placed on the upper surface of the limiting ring 41 in the tank body 1, and then the elastic block 46 is squeezed by covering the tank cover 2, and through the connecting rod 45 and the compressed spring 44, the collection box 42 is fixed, so that the broken scum particles are collected in the collection box 42, and the remaining fermentation liquid flows out from the bottom of the filter hole 48. And when it is necessary to clean the collection box 42, the operator can easily take it out of the tank body 1 through the handle 47.

[0028] The shell-breaking component 3 includes a motor 31 arranged on the upper surface of the tank cover 2, and a rotating shaft 32 fixedly installed at the output end of the motor 31. One end of the rotating shaft 32 penetrates through the inside of the tank cover 2 and the collection box 42. A crushing paddle 33 is fixedly sleeved on the outer surface of the rotating shaft 32, and the crushing paddle 33 is located inside the collection box 42. The motor 31 drives the rotating shaft 32, and then drives the crushing paddle 33 to rotate, so as to stir the materials inside the collection box 42 and prevent caking.

[0029] A cylinder 5 is arranged through the center of the bottom of the collection box 42. A bearing 51 is arranged on the inner wall of the cylinder 5. The outer surface of the rotating shaft 32 is movably connected with the bearing 51, reducing the friction between the rotating shaft 32 and the cylinder 5 and ensuring that the rotating shaft 32 rotates more smoothly.

[0030] A reciprocating threaded rod 6 is fixedly installed at the bottom of the rotating shaft 32. The reciprocating threaded rod 6 is located below the collection box 42. A sleeve 61 is threadedly connected to the outer surface of the reciprocating threaded rod 6. A rotating rod 62 is arranged on the outer surface of the sleeve 61. One end of the rotating rod 62 is provided with a scraping block 63. The outer surface of the scraping block 63 is in contact with the inner wall of the tank body 1. The reciprocating threaded rod 6 drives the sleeve 61 to move up and down below the collection box 42 through the rotation of the rotating shaft 32. Therefore, the rotating rod 62 and the scraping block 63 also move accordingly, so as to not only prevent fine slag from sticking to the wall, but also collide with the bottom of the collection box 42 to prevent the scum from blocking the filter hole 48.

[0031] A feed hopper 7 is arranged on the upper surface of the tank cover 2 for convenient feeding.

[0032] An exhaust pipe 8 is provided on the upper part of the can lid 2. A pressure valve 81 is provided on the outer surface of the exhaust pipe 8. A pressure gauge 82 is provided on the upper surface of the can lid 2. The detection needle of the pressure gauge 82 penetrates into the interior of the can lid 2. The pressure valve 81 is used to adjust the pressure inside the tank body 1, and the pressure gauge 82 displays the pressure inside the tank body 1, so as to monitor and control the pressure inside the tank body 1 and ensure safe operation.

[0033] A slag storage box 9 is provided inside the tank body 1. A slag discharge pipe 91 is provided inside the slag storage box 9. One end of the slag discharge pipe 91 penetrates through the outer surface of the tank body 1. A valve 92 is provided on the outer surface of the part where the slag discharge pipe 91 penetrates out. The fine crushed slag scraped off by the scraping block 63 and the part of the floating slag not collected by the collection box 42 will both precipitate in the slag storage box 9 and be discharged through the slag discharge pipe 91, so as to collect the crushed slag more comprehensively.

[0034] Specifically, place the collection box 42 on the upper surface of the limit ring 41 inside the tank body 1, then squeeze the elastic block 46 by covering the can lid 2, and through the connecting rod 45 and the compression spring 44, the collection box 42 is fixed. Add materials through the feed hopper 7, then start the motor 31 to drive the rotating shaft 32, and then drive the crushing paddle 33 to rotate, so as to stir the materials inside the collection box 42 to prevent caking. Therefore, the crushed floating slag particles are collected in the collection box 42, and the remaining fermentation liquid flows out from the bottom of the filter holes 48. And when it is necessary to clean the collection box 42, the operator can easily take it out of the tank body 1 through the handle 47. Also, because a cylinder 5 is penetrated through the center of the bottom of the collection box 42, a bearing 51 is provided on the inner wall of the cylinder 5, and the outer surface of the rotating shaft 32 is movably connected with the bearing 51, so the friction between the rotating shaft 32 and the cylinder 5 can be reduced, ensuring that the rotating shaft 32 rotates more smoothly. In addition, because a reciprocating threaded rod 6 is fixedly installed at the bottom of the rotating shaft 32, the reciprocating threaded rod 6 drives the sleeve 61 to move up and down below the collection box 42 through the rotation of the rotating shaft 32. Therefore, the rotating rod 62 and the scraping block 63 also move accordingly, so that not only can the fine crushed slag be prevented from sticking to the wall, but also the bottom of the collection box 42 can be collided to prevent the floating slag from blocking the filter holes 48. At the same time, the fine crushed slag scraped off by the scraping block 63 and the part of the floating slag not collected by the collection box 42 will both precipitate in the slag storage box 9 and be discharged through the slag discharge pipe 91, so as to collect the crushed slag more comprehensively. Finally, because an exhaust pipe 8 is provided on the upper part of the can lid 2 and a pressure valve 81 is provided on the outer surface of the exhaust pipe 8, the pressure valve 81 is used to adjust the pressure inside the tank body 1. And a pressure gauge 82 is provided on the upper surface of the can lid 2, and the detection needle of the pressure gauge 82 penetrates into the interior of the can lid 2, so that the pressure gauge 82 can display the pressure inside the tank body 1, so as to monitor and control the pressure inside the tank body 1 and ensure safe operation.
