[0003] The existing anaerobic tank for kitchen use has only one pipe at the edge of the tank body. When discharging mud and sand, only a small amount of mud and sand near the pipe can be discharged. The discharge efficiency of mud and sand is low, which reduces the effective volume in the anaerobic tube. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 2 As shown in Figures 3 and 4, the utility model provides a technical solution: a new type of CSTR anaerobic tank, comprising: a tank body 1 with a stirring part arranged inside; a mud pumping pipe 9 is vertically slidably installed at the bottom of the tank body 1, the bottom of the tank body 1 is provided with a through hole cooperating with the mud pumping pipe 9, a strip hole is arranged on the side of the mud pumping pipe 9, a sealing cover 8 is fixedly connected to the top of the mud pumping pipe 9, the sealing cover 8 is a metal plate with a sealing gasket installed at the bottom, a pipe assembly is installed at the bottom of the mud pumping pipe 9, and a lifting part is provided at the bottom of the pipe assembly. When the lifting part drives the mud pumping pipe 9 to rise, the strip hole pumps and discharges the inside of the tank body 1, and when the lifting part drives the mud pumping pipe 9 to descend, the thickness of the bottom of the tank body 1 blocks the strip hole; a toggle part is placed inside the tank body 1, the toggle part includes a plurality of toggle blades 6 with an arc structure, and a staggered notch 7 cooperating with the sealing cover 8 is provided in the middle of the toggle blade 6.

[0023] It should be noted that, when the utility model needs to pump out the accumulated mud and sand in the internal anaerobic tank, the mud pumping pipe 9 is lifted by the lifting part, and the mud pumping pipe 9 passes through the through hole, and the sealing cover 8 is separated from the through hole. At this time, the mud pumping pipe 9 leaks out from the bottom of the tank body 1 and is connected to the mud pumping pipe 9 through the sand pumping pump. Under the action of negative pressure, the mud and sand enter the pipeline assembly through the mud pumping pipe 9 and are discharged. During this period, the shifting blade 6 rotates inside the tank body 1 to shift the internal mud and sand so that it can contact the mud pumping pipe 9. To prevent mud and sand from accumulating in a fixed position and making it inconvenient to clean it, after cleaning, the residual mud and sand are discharged by flushing, and then the lifting part drives the mud pumping pipe 9 to descend, and the strip holes on the side of the mud pumping pipe 9 are received in the thickness of the bottom of the tank body 1, that is, the thickness of the bottom of the tank body 1 is greater than the height of the strip holes. A rubber ring is provided on the outside of the mud pumping pipe 9 to enable the mud pumping pipe 9 to move downward. When the strip holes are misaligned with the bottom of the tank body 1, the mud pumping pipe 9 seals the inside of the tank body 1, and the sealing cover 8 can also seal the through hole.

[0024] See also Figure 1 As shown, the stirring part includes a cover plate 3 fixedly connected to the top of the tank body 1, a No. 1 motor 4 is fixedly connected to the top of the cover plate 3, and a stirring shaft 5 is fixedly connected to the output end of the No. 1 motor 4.

[0025] It should be noted that the first motor 4 of the present invention mixes and stirs the interior of the tank body 1 through the stirring shaft 5 to facilitate the reaction inside.

[0026] See also Figure 4 As shown, the pipeline assembly includes a lifting plate 16, the bottom of the lifting plate 16 is fixedly connected to the hydraulic cylinder 12, the output end of the hydraulic cylinder 12 passes through the lifting plate 16 and is fixedly connected to the bottom of the tank body 1, the bottom of the tank body 1 is fixedly connected to the limiting rod 14, and the limiting rod 14 is slidably connected to the lifting plate 16.

[0027] It should be noted that, when the mud pumping pipe 9 is raised or lowered, the output end of the hydraulic cylinder 12 is extended and retracted, and the hydraulic cylinder 12 drives the lifting plate 16 to rise and fall on the outside of the limiting rod 14, thereby driving the mud pumping pipe 9 to rise and fall. Two limiting rods 14 are symmetrically arranged to ensure the stability of the lifting plate 16 when it is raised or lowered.

[0028] See also Figure 4 As shown, the bottom of the mud suction pipe 9 is fixed with a branch pipe 11, and the branch pipe 11 is fixed with the lifting plate 16. An annular pipe 10 is provided on the outside of the lifting plate 16. One end of the branch pipe 11 is connected to the annular pipe 10, and a connecting pipe 13 is fixed to the bottom of the annular pipe 10.

[0029] It should be noted that a valve is provided in the middle of the connecting pipe 13 of the utility model and one end of the connecting pipe 13 is connected to the input end of the sand pump. The sand pump generates negative pressure in the annular pipe 10 through the connecting pipe 13. Under the action of pressure, the mud and sand enter the branch pipe 11 through the strip holes on the outside of the mud pumping pipe 9, and then enter the annular pipe 10 from the end of the branch pipe 11, enter the connecting pipe 13 through the annular pipe 10, and then be discharged by the sand pump.

[0030] See also Figure 4 As shown, the bottom of the tank body 1 is fixedly connected to the No. 2 motor 15, and the shifting blades 6 are fixedly connected to the outside of the output shaft of the No. 2 motor 15 at equal distances with the output shaft of the No. 2 motor 15 as the center.

[0031] It should be noted that the No. 2 motor 15 of the utility model drives the toggle blade 6 to rotate. The toggle blade 6 is an arc-shaped structure. The toggle blade 6 pushes the mud and sand back and forth toward the position of the mud pumping pipe 9, making it convenient for the mud pumping pipe 9 to extract the mud and sand. The offset notch 7 in the middle of the toggle blade 6 corresponds to the sealing cover 8. When the sealing cover 8 is raised, the offset notch 7 passes through the outside of the sealing cover 8 and will not collide with each other.

[0032] See also Figure 1 、 2 As shown in Figures 3 and 3, a support base 2 is fixed to the bottom of the tank body 1, and holes are equidistantly arranged on the outside of the support base 2.

[0033] It should be noted that the support base 2 of the present invention can ensure the stability of the tank body 1 and can create a height difference between the tank body 1 and the ground, making it convenient for the hydraulic cylinder 12 to drive the lifting plate 16 to move up and down.
