Description

Technical Field

[0001] This utility model belongs to the field of waste fermentation technology, specifically relating to a high-temperature waste fermentation device. Background Technology

[0002] Waste fermentation is divided into aerobic and anaerobic fermentation. Regardless of the fermentation method, a large amount of gases such as methane, ammonia, hydrogen sulfide, thiols, thioethers, alcohols, aldehydes, ketones, esters, alkanes, alkenes, halogenated hydrocarbons, terpenes, and aromatic hydrocarbons will be produced. Some of these gases are combustible, so using the gases produced after organic waste fermentation to generate electricity is a major method of organic waste treatment. By creating a suitable high-temperature environment, the decomposition and transformation of organic components in waste by microorganisms can be promoted, and the reduction, harmlessness, and resource recovery of waste can be achieved in a short period of time.

[0003] Existing high-temperature fermentation devices for waste have serious deficiencies in their heating layout. The heating element is arranged around the inner wall of the tank, and the heating liquid is injected from one end and discharged from the other, directly resulting in severely uneven heat distribution inside the tank. The waste in the middle section is insufficiently heated because it is far from the heating source, while the area near the tank wall is overheated. Simultaneously, as the heat transfer oil flows and the temperature continuously decreases, a temperature difference also arises between the left and right sides of the tank, creating an extremely unfavorable thermal environment. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature fermentation device for waste to solve the problem of uneven heating inside existing tanks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature fermentation device for waste, comprising a tank, a stirring mechanism, and a heating mechanism;

[0006] The stirring mechanism includes a rotating shaft and several stirring components. The stirring components are evenly spaced and arranged in a spiral shape. The middle part of each stirring component is connected to the rotating shaft.

[0007] The heating mechanism includes a heating tube, which is spirally arranged in the inner wall of the tank. The heating tube is composed of two spiral heating tubes connected by a T-shaped tube.

[0008] Furthermore, the tank is arranged horizontally, and the top and bottom of the tank are respectively provided with a waste inlet and a waste outlet.

[0009] Furthermore, a transverse block is fixedly fitted onto one side of the waste inlet, one end of the transverse block is located inside the waste inlet, and a gas passage groove is opened inside the transverse block.

[0010] Furthermore, the gas passage is L-shaped.

[0011] Furthermore, the stirring mechanism also includes a motor, which is installed on one side of the tank, with the motor's output shaft inserted inside the tank, and one end of the rotating shaft mounted on the motor's output shaft.

[0012] Furthermore, two scrapers are connected to both sides of each of the plurality of stirring components.

[0013] Furthermore, the two scrapers are arranged in a spiral shape, and the sides of the two scrapers that are far apart from each other are attached to the inside of the tank.

[0014] Furthermore, the end of the transverse block located at the waste inlet is inclined downwards.

[0015] Furthermore, the end of the transverse block furthest from the waste inlet is connected to a gas storage tank via a pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This high-temperature waste fermentation device employs a central liquid inlet and two-end drainage heating element, effectively reducing the temperature difference between the left and right sides of the tank. Simultaneously, it drives the agitator in a circular motion; its unique spiral structure acts like a powerful propeller, continuously propelling the waste along a spiral trajectory within the tank, significantly enhancing the mixing effect. This thorough agitation accelerates the even transfer of heat, effectively eliminating temperature differences between the center and the tank walls, and between the left and right sides, caused by deficiencies in the heating layout. This prevents uneven heating, effectively optimizes the fermentation environment, and promotes efficient waste fermentation. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments.

[0025] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0026] Please see Figure 1-5 This utility model provides a high-temperature fermentation device for waste, including a tank 10, a stirring mechanism 20, and a heating mechanism 30;

[0027] The tank body 10 is arranged horizontally, and the top and bottom of the tank body 10 are respectively provided with a garbage inlet 101 and a garbage outlet 102. Both the garbage inlet 101 and the garbage outlet 102 are provided with a cover or valve to seal the garbage inlet 101 and the garbage outlet 102.

[0028] A transverse block 110 is fixedly fitted to one side of the waste inlet 101. The left side of the transverse block 110 is located inside the waste inlet 101, and an L-shaped gas passage 1101 is opened inside the transverse block 110. The right side of the transverse block 110 is connected to a gas storage tank through a pipe. As the gas generated by the tank 10 floats upward, it is stored in the gas storage tank through the gas passage 1101. The waste entering the waste inlet 101 will not enter the L-shaped gas passage 1101.

[0029] The top left side of the horizontal block 110 is tilted downwards to the left to facilitate the sliding of waste.

[0030] Please see Figure 1-2 The mixing mechanism 20 includes a motor 210, a rotating shaft 220, and mixing components 230. The motor 210 is installed in the middle left side of the tank 10, and the output shaft of the motor 210 is inserted inside the tank 10. The left end of the rotating shaft 220 is installed on the output shaft of the motor 210. There are several mixing components 230, which are evenly spaced and arranged in a spiral shape. The middle of each mixing component 230 is connected to the rotating shaft 220. When the motor 210 is started, the motor 210 drives the rotating shaft 220 to rotate, which in turn drives the mixing components 230 to rotate. Since the components are arranged in a spiral shape, they can further push the garbage to tumble, improving the garbage mixing effect.

[0031] Several agitators 230 are connected to two scrapers 240 on both sides. The two scrapers 240 are arranged in a spiral shape, and the side of the two scrapers 240 that is far away from each other is attached to the inside of the tank 10. The scrapers 240 rotate with the agitators 230 and scrape the garbage on the tank wall.

[0032] Please see Figure 3-4 The heating mechanism 30 includes a heating tube 310, which is spirally arranged inside the inner wall of the tank 10. The heating tube 310 is formed by two spiral heating tubes 311 connected by a T-shaped tube 312, so that the heating tube 310 is fed into the middle of the heating tube and the liquid is discharged from the side of the two spiral heating tubes 311 that are far apart from each other, which can reduce the temperature difference between the left and right sides inside the tank 10.

[0033] The working principle and usage process of this utility model are as follows: the garbage outlet 102 is sealed, the garbage outlet 101 is opened, and the garbage enters the tank 10 from the garbage inlet 101. The garbage inlet 101 is then closed. The motor 210 is started, and the motor 210 drives the rotating shaft 220 to rotate. The rotating shaft 220 drives several stirring components 230 to rotate. Since the components are arranged in a spiral shape, they can further push the garbage to tumble and improve the garbage stirring effect. At the same time as stirring, heat-conducting liquid is injected through the T-shaped pipe 312. The heat-conducting liquid is discharged from the side of the two spiral heating pipes 311 that are far apart from each other, thus heating the inside of the tank 10.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
