Description

Technical Field

[0001] This utility model relates to the field of fermentation technology, and in particular to an intermittent feeding tank-type aerobic fermenter. Background Technology

[0002] An aerobic fermentation machine is a device that uses the activity of microorganisms to decompose and mature organic waste under aerobic conditions.

[0003] Chinese patent application publication number CN216808533U discloses an intermittent feeding tank-type aerobic fermenter. In this patent, materials are added to the inside of the hopper and enter the tank through the bottom feed port. The drive mechanism drives the rotating shaft to rotate, so that the stirring blades stir the materials inside, which can better disperse the materials for fermentation and avoid the accumulation of a large amount of materials in the same place. When sampling is required, the sampling tube rotates inside the installation tube, so that the sampling slot is rotated to connect with the feed trough.

[0004] When using the aforementioned patent, we found that the device does not have the ability to clean the tank, resulting in a certain amount of dirt and bacteria on the tank, which affects the use of the tank. Therefore, we proposed an intermittent feeding tank-type aerobic fermenter. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intermittent feeding tank-type aerobic fermenter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intermittent feeding tank-type aerobic fermenter includes a tank body. A fixing plate is fixed inside the tank body, and a stirring mechanism for stirring materials is installed on the fixing plate. A cleaning mechanism for cleaning the inside of the tank body is also installed inside the tank body. A water injection pipe is fixedly connected to the top of the tank body, and a distribution plate is connected to the bottom of the water injection pipe. A nozzle is installed at the bottom of the distribution plate. A feed hopper is installed on the top side of the tank body, and a discharge pipe is connected to the bottom side of the tank body. A valve is installed on the discharge pipe.

[0008] Preferably, the stirring mechanism includes a first motor, a lead screw, a slider, a rack, a first rotating shaft, a gear, and a stirring blade. The first motor is installed on the side of the tank. The output shaft of the first motor rotates through the tank and is connected to the lead screw. A slider is threaded onto the lead screw. A rack is fixed to the side of the slider. The first rotating shaft is rotatably installed inside a fixed plate. A gear is fixedly sleeved at the bottom of the first rotating shaft. The rack meshes with the gear for transmission. A stirring blade is fixed on the first rotating shaft.

[0009] Preferably, a limiting groove is formed inside the tank, and a limiting block is fixed to the side of the slider, with the limiting block slidably installed in the limiting groove.

[0010] Preferably, the cleaning mechanism includes a second motor, a second rotating shaft, a crossbar, a mounting plate, and a cleaning brush. The second motor is mounted on the top of the tank. The output shaft of the second motor rotates through the tank and is connected to the second rotating shaft. A crossbar is fixed to the bottom of the second rotating shaft. Mounting plates are fixed to the bottom of both ends of the crossbar. A cleaning brush is mounted on the mounting plate.

[0011] Preferably, the tank body has a through hole on its side, and an observation screen is fixed inside the through hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the first motor is started, and through the threaded transmission between the lead screw and the slider, the slider drives the rack to move. Through the threaded transmission between the rack and the gear, the gear drives the first rotating shaft to rotate, which in turn drives the stirring blade to rotate. This allows the stirring blade to stir and mix the material, thus facilitating and improving the fermentation efficiency of the material.

[0014] 2. In this utility model, starting the second motor causes the second rotating shaft to rotate the crossbar, which in turn causes the mounting plate to rotate. This allows the mounting plate to rotate the cleaning brush inside the tank, facilitating the cleaning of the tank's interior. Attached Figure Description

[0021] Reference Figure 2 , Figure 3 The stirring mechanism 3 includes a first motor 31, a lead screw 32, a slider 33, a rack 34, a first rotating shaft 35, a gear 36, and a stirring blade 37. The first motor 31 is installed on the side of the tank 1. The output shaft of the first motor 31 rotates through the tank 1 and is connected to the lead screw 32. The slider 33 is threaded onto the lead screw 32. A limit groove is formed inside the tank 1. A limit block 4 is fixed to the side of the slider 33 and slides in the limit groove. A rack 34 is fixed to the side of the slider 33. The first rotating shaft 35 is rotatably mounted on the fixed... Inside plate 2, a gear 36 is fixedly sleeved at the bottom of the first rotating shaft 35. The rack 34 meshes with the gear 36 for transmission. A stirring blade 37 is fixed on the first rotating shaft 35. When the first motor 31 is started, the slider 33 drives the rack 34 to move through the threaded transmission between the lead screw 32 and the slider 33. Through the threaded transmission between the rack 34 and the gear 36, the gear 36 drives the first rotating shaft 35 to rotate, which in turn drives the stirring blade 37 to rotate. This allows the stirring blade 37 to stir and mix the material, thus facilitating and improving the fermentation efficiency of the material.

[0022] Reference Figure 3 The cleaning mechanism 5 includes a second motor 51, a second rotating shaft 52, a crossbar 53, a mounting plate 54, and a cleaning brush 55. The second motor 51 is mounted on the top of the tank 1. The output shaft of the second motor 51 rotates through the tank 1 and is connected to the second rotating shaft 52. The bottom of the second rotating shaft 52 is fixed with the crossbar 53. The bottom ends of the crossbar 53 are fixed with the mounting plate 54. The cleaning brush 55 is mounted on the mounting plate 54. When the second motor 51 is started, the second rotating shaft 52 drives the crossbar 53 to rotate, which in turn drives the mounting plate 54 to rotate. This allows the mounting plate 54 to drive the cleaning brush 55 to rotate inside the tank 1, facilitating the cleaning of the inside of the tank 1.

[0023] Working principle: The material is fed into the tank 1 through the feed hopper 9 for fermentation. The first motor 31 is started, and the slider 33 drives the rack 34 to move through the threaded transmission between the lead screw 32 and the slider 33. The rack 34 drives the gear 36 to rotate through the threaded transmission between the rack 34 and the gear 36. The gear 36 drives the first rotating shaft 35 to rotate, which in turn drives the stirring blade 37 to rotate. This allows the stirring blade 37 to stir and mix the material, thus improving the fermentation efficiency. After the tank 1 is used, cleaning liquid is injected into the tank 1 through the nozzle 8. The second motor 51 is started, and the second rotating shaft 52 drives the crossbar 53 to rotate, which in turn drives the mounting plate 54 to rotate. This allows the mounting plate 54 to drive the cleaning brush 55 to rotate inside the tank 1, facilitating the cleaning of the inside of the tank 1.
