Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to a fermentation device for bio-fertilizer processing which is not easy to be blocked. Background Art

[0002] Biofertilizer, also known as microbial fertilizer, bacterial fertilizer, and inoculant, is a product with fertilizer effect made from living microorganisms or their life activities and their products. The existing patent (Announcement No.: CN215440270U) discloses a fermentation device for biofertilizer processing. The utility model has the functions of heating, ventilation and stirring by setting a hot stirring mechanism. The heat and the transported oxygen can directly act on the center of the pile, with high thermal efficiency, uniform fermentation of materials, and high efficiency. However, in actual applications, fermentation will produce tail gas that is harmful to the human body and pollutes the environment. Although the tail gas can be discharged from the exhaust port to the tail gas treatment equipment, because the box is not completely closed, the tail gas can still be discharged from the feed hopper upwards from the box, causing the tail gas to pollute the environment, which is not conducive to practical application. For this reason, we propose a fermentation device for biofertilizer processing that is not easy to clog. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a fermentation device for bio-fertilizer processing which is not easy to be blocked.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A fermentation device for bio-fertilizer processing that is not easy to be clogged is designed, comprising a box body connected to a feed hopper and an exhaust pipe, the top of the feed hopper is connected to a cover plate driven by air pressure to move up and down, the bottom of the cover plate is provided with a seal that cooperates with the inner wall of the feed hopper, the seal comprises a rubber sleeve and an adsorption layer, a rotating shaft connected to a motor transmission is provided in the box body, a spiral blade and a crushing blade are installed on the rotating shaft, a feeding pipe is connected to the bottom of the box body, and a ventilation mechanism and a spray mechanism are provided above the spiral blade.

[0006] In the above solution, a bracket is fixed on the top of the box body, and a cylinder whose stroke end is connected to the cover plate is installed on the bracket.

[0007] In the above scheme, a mounting groove for mounting the rubber sleeve is provided at the bottom of the cover plate, the adsorption layer is located inside the rubber sleeve, a hook surface layer is fixed on the top of the adsorption layer, and a fur surface layer is fixed on the bottom of the cover plate.

[0008] In the above scheme, the adsorption layer is set as an activated carbon adsorption layer.

[0009] In the above scheme, the upper part of the box body is rectangular, the lower part is horizontal columnar, and the box body is supported by a base.

[0010] In the above solution, the ventilation mechanism includes an oxygen concentration sensor and a temperature sensor installed on the top of the box body. A plurality of ventilation pipes penetrate horizontally through the box body, and nozzles are installed on the ventilation pipes.

[0011] In the above solution, the spraying mechanism includes a spray pipe, and a shower head facing downward is installed on the spray pipe.

[0012] The advantages and beneficial effects of the present utility model are as follows: By setting a cover plate and a seal, the opening of the feed hopper is blocked by the cover plate. After feeding, the cover plate is placed on the top of the feed hopper to prevent the fermentation tail gas from discharging upward from the opening of the feed hopper. In cooperation with the seal, the sealing performance of the cover plate is improved. Compared with the prior art, not only can the feed hopper be sealed, but also the adsorption layer located in the rubber sleeve can be used to adsorb the fermentation tail gas, thereby reducing the fermentation tail gas in the box body, reducing the tail gas treatment volume, reducing energy consumption. In cooperation with the cylinder, by controlling the length of the piston rod of the cylinder, the cover plate moves up and down, which can not only facilitate the opening of the feed hopper but also facilitate the closing of the feed hopper, improving the degree of automation. By setting a motor, a rotating shaft, a spiral blade and a crushing blade, the motor provides power to the rotating shaft, so that the rotating shaft drives the spiral blade and the crushing blade. As the spiral blade rotates, the fertilizer is continuously conveyed forward, and at the same time, the crushing blade is used to cut and crush the large fertilizer blocks, effectively avoiding the blockage of the feeding pipe and ensuring normal feeding.

[0019] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a fermentation device for bio-fertilizer processing that is not easily blocked, including a box body 1 connected to a feed hopper 3 and a tail gas pipe 17. The raw materials are added into the box body 1 by using the feed hopper 3, and the tail gas pipe 17 is connected to the tail gas treatment equipment to treat the fermentation tail gas so that it meets the national emission standards and avoid environmental pollution. The top of the feed hopper 3 is connected with a cover plate 4 that is driven up and down by air pressure;

[0020] Furthermore, a support 6 is fixed on the top of the box body 1, and a cylinder 7 with a stroke end connected to the cover plate 4 is installed on the support 6. The cylinder 7 is vertically installed at the top of the support 6, so as to facilitate the lifting of the cover plate 4;

[0021] A seal 5 that cooperates with the inner wall of the feed hopper 3 is provided at the bottom of the cover plate 4. The seal 5 includes a rubber sleeve 51 and an adsorption layer 54. The rubber sleeve 51 is mainly responsible for providing a sealing effect, and the adsorption layer 54 is used to adsorb the tail gas moving upward along the feed hopper 3, not only preventing the tail gas from escaping, but also reducing the total amount of tail gas in the box body 1;

[0022] Furthermore, an installation groove 20 for installing the rubber sleeve 51 is opened at the bottom of the cover plate 4. The top of the rubber sleeve 51 is fixed in the installation groove 20, the adsorption layer 54 is located inside the rubber sleeve 51, a hook layer 53 is fixed at the top of the adsorption layer 54, and a hair layer 52 is fixed at the bottom of the cover plate 4;

[0023] Specifically, the adsorption layer 54 can be fixed on the hook layer 53 through nano double-sided tape. By using the characteristic of mutual adhesion between the hook layer 53 and the hair layer 52, the adsorption layer 54 and the cover plate 4 are fixed, which is convenient for installation.

[0024] Furthermore, the adsorption layer 54 is set as an activated carbon adsorption layer; activated carbon has strong adsorption ability, can effectively adsorb tail gas, and is easy to obtain and use conveniently;

[0025] Specifically, by providing a cover plate 4 and a sealing member 5, the cover plate 4 is used to cover the opening of the feed hopper 3. After the feeding is completed, the cover plate 4 is placed on the top of the feed hopper 3 to prevent the fermentation exhaust gas from being discharged upward from the opening of the feed hopper 3. In conjunction with the sealing member, the sealing performance of the cover plate 4 is improved. Compared with the prior art, not only can the feed hopper 3 be sealed, but also the adsorption layer 54 located in the rubber sleeve 51 can be used to adsorb the fermentation exhaust gas, thereby reducing the fermentation exhaust gas in the box body 1, reducing the exhaust gas treatment volume, and reducing energy consumption. In conjunction with the cylinder 7, the cover plate 4 can be moved up and down by controlling the piston rod length of the cylinder 7, which can facilitate the opening and closing of the feed hopper 3, thereby improving the degree of automation.

[0026] A rotating shaft 8 connected to the motor 16 is provided in the box body 1, and both ends of the rotating shaft 8 are movably installed with the box body.

The box body 1 is supported by a base 2, and the base 2 is fixed to the bottom of the box body 1. The base 2 is provided with a plug hole for passing the feeding pipe 11;

[0028] Specifically, a motor 16, a rotating shaft 8, a spiral blade 9 and a crushing blade 10 are provided. The motor 16 is used to provide power to the rotating shaft 8, so that the rotating shaft drives the spiral blade 9 and the crushing blade 10. As the spiral blade 9 rotates, the fertilizer is continuously transported forward. At the same time, the crushing blade 10 is used to cut and crush large pieces of fertilizer, effectively preventing the fertilizer from clogging the feed pipe 11 and ensuring normal feed discharge.

[0029] A ventilation mechanism and a spray mechanism are provided above the spiral blade 9;

[0030] Further, the ventilation mechanism includes an oxygen concentration sensor 19 and a temperature sensor 18 installed on the top of the box body 1, and a plurality of ventilation pipes 12 are horizontally passed through the box body 1, and nozzles 13 are installed on the ventilation pipes 12;

The oxygen pipe is used to transport oxygen, and the oxygen concentration sensor 19 is used to detect the oxygen concentration in the box body 1. When the oxygen concentration is too low, oxygen is transported into the box body 1 through the oxygen pipe. The temperature control pipe is used to transport a heat exchange medium, which can transport either a cold medium or a hot medium. The temperature sensor 18 is used to detect the temperature in the box body 1. When the temperature is too low, a hot medium is transported into the box body 1 through the temperature control pipe. When the temperature is too high, a cold medium is transported into the box body 1 through the temperature control pipe, so as to keep the box body 1 at an appropriate temperature and improve the fermentation efficiency.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
