The utility model moves the solid excrement through the scraping mechanism, prevents the solid excrement from accumulating near the excrement feed inlet below in the horizontal reaction kettle, causes the thermophilic bacterial population to be unable to contact the solid excrement fully, thereby the efficiency of the microorganism treating the solid excrement is influenced.

Description

Technical Field

[0001] This utility model relates to the field of manure treatment technology, and in particular to a horizontal fermentation reactor for treating livestock and poultry manure. Background Technology

[0002] Manure fermentation is a process in which microorganisms such as bacteria, fungi, and actinomycetes decompose organic matter in livestock and poultry manure under aerobic conditions and convert it into stable humus and inorganic nutrients. Its core technology is to cultivate microorganisms in a reactor and use the cultivated microorganisms to recycle manure resources in the reactor.

[0003] Existing reactors are broadly classified into two categories: horizontal and vertical. Horizontal reactors are widely used due to their high fermentation efficiency, making them the most common type. However, when fermenting manure in a horizontal reactor, the manure enters from one end of the reactor. Since manure consists of both solid and liquid substances, although the liquid manure can be evenly distributed within the reactor, the solid manure tends to accumulate near the feed inlet. This results in only the outer layer of solid manure being fermented by microorganisms, thus affecting the efficiency of microbial treatment of solid manure. Utility Model Content

[0004] This invention provides a horizontal fermentation reactor for treating livestock and poultry manure, aiming to solve the technical problem that solid manure tends to accumulate near the feed inlet of the reactor, resulting in only the outer layer of solid manure being fermented by microorganisms, thus affecting the efficiency of microbial treatment of solid manure.

[0005] The technical solution of this utility model is as follows: A horizontal fermentation reactor for treating livestock and poultry manure includes a horizontal reactor with two ladders on the front side and two inspection ports on the upper side, the ladders being located in front of adjacent inspection ports. A manure inlet and a microbial inlet are provided on the upper side of the horizontal reactor. Drainage outlets are provided on the lower parts of both sides of the horizontal reactor. An exhaust outlet is provided on one side of the horizontal reactor. Symmetrically distributed scraping mechanisms are provided inside the horizontal reactor to scrape off solid manure adhering to the inner wall of the horizontal reactor. Symmetrically distributed drive components are provided inside the horizontal reactor to drive the adjacent scraping mechanisms to rotate.

[0006] Furthermore, the scraping mechanism includes a sealing box, which is installed inside the horizontal reactor. The sealing box is rotatably connected to a rotating shaft. A connecting frame is installed at the end of the rotating shaft away from the adjacent sealing box. A scraper plate evenly distributed in the circumferential direction is installed on the side of the connecting frame away from the adjacent sealing box.

[0007] Furthermore, the scraper blades are distributed in a spiral shape within the horizontal reactor.

[0008] Furthermore, the drive assembly includes a drive motor, which is mounted on the upper side of the horizontal reactor via a bracket. The output shaft of the drive motor is equipped with a second rotating shaft, which passes through the upper side wall of the horizontal reactor and through the adjacent sealed box. The second rotating shaft and the adjacent first rotating shaft are driven by a bevel gear set, and the bevel gear set is located inside the adjacent sealed box.

[0009] Furthermore, heating pipes are installed on both sides of the horizontal reactor, and the heating pipes pass through the side wall of the horizontal reactor and enter it.

[0010] Furthermore, a stirring rack is fixedly connected to the lower end of the second rotating shaft.

[0011] Furthermore, the symmetrically distributed stirring racks are staggered.

[0012] Furthermore, a pusher plate 1 and a pusher plate 2 are installed circumferentially evenly distributed between the stirring rack and the adjacent rotating shaft 2, with the pusher plate 2 located on the upper side of the adjacent pusher plate 1.

[0013] Furthermore, both the first pusher plate and the second pusher plate are inclined and distributed on adjacent rotating shafts, and the first pusher plate and the second pusher plate on the same rotating shaft are symmetrically distributed in a horizontal figure-eight shape.

[0014] The beneficial effects of this utility model are: This utility model moves solid manure through a scraping mechanism, preventing solid manure from accumulating near the manure inlet in the horizontal reactor, which would prevent thermophilic bacteria from fully contacting the solid manure, resulting in only the outer layer of solid manure being fermented by microorganisms, thus affecting the efficiency of microbial treatment of solid manure.

[0015] This invention uses four rotating scraper blades to scrape away solid waste at the bottom of a horizontal reactor and to turn the waste over, thereby preventing the solid waste from clumping together. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] A horizontal fermentation reactor for treating livestock and poultry manure, such as Figures 1-4 As shown, the reactor includes a horizontal reactor 101. Two ladders 102 are provided on the front side of the horizontal reactor 101. Two symmetrically arranged inspection ports 103 are provided on the upper side of the horizontal reactor 101, with the ladders 102 located in front of the adjacent inspection ports 103. A manure inlet 104 is provided on the upper right side of the horizontal reactor 101, and a microbial inlet 105 is provided on the upper left side of the horizontal reactor 101. Drainage ports 106 are provided on the lower parts of both sides of the horizontal reactor 101, and an exhaust port 107 is provided on the upper left side of the horizontal reactor 101. Two symmetrically arranged scraping mechanisms are provided inside the horizontal reactor 101 to scrape off solid manure adhering to the inner wall of the horizontal reactor 101. Two symmetrically arranged driving components are provided inside the horizontal reactor 101 to drive the adjacent scraping mechanisms to rotate.

[0024] Specifically, in actual use, microbial flora (thermophilic flora used in this invention) is first added to the horizontal reactor 101 through the microbial inlet 105. Then, the thermophilic flora in the horizontal reactor 101 is cultivated until it occupies 10% to 30% of the effective volume of the horizontal reactor 101. Subsequently, manure is added to the horizontal reactor 101 through the manure inlet 104. During the manure addition process, two drive components are activated, which drive the adjacent scraping mechanism to work until the manure in the horizontal reactor 101 is completely fermented. The organic fertilizer in the horizontal reactor 101 is discharged through the drain 106, and the drive components are turned off. During the fermentation process, the gas produced by the thermophilic flora when decomposing the manure is discharged through the exhaust port 107.

[0025] like Figures 2-4 As shown, the scraping mechanism includes a sealing box 201, which is installed inside the horizontal reactor 101. The sealing box 201 is rotatably connected to a rotating shaft 202. A connecting frame 203 is installed at the end of the rotating shaft 202 away from the adjacent sealing box 201. Four scraping plates 204 are evenly distributed circumferentially on the side of the connecting frame 203 away from the adjacent sealing box 201. The scraping plates 204 are distributed in a spiral shape inside the horizontal reactor 101.

[0026] Taking the scraping mechanism on the right as an example, the drive component transmission shaft 202 rotates, and the shaft 202 drives the four scraper plates 204 to rotate counterclockwise along the inner wall of the horizontal reactor 101 through the connecting frame 203. Figure 4 From the perspective of [the above], the solid waste entering the horizontal reactor 101 is conveyed to the right. Specifically, this can be understood as follows: when the scraper 204 rotates and is directly below, the scraper 204 continues to rotate, driving the material located on its front side (in [the following context]). Figure 4 From the perspective of [the object], the feces and sludge move synchronously until the scraper plate 204 rotates to the right. During this process, the feces and sludge on the front side of the scraper plate 204 move forward along the spiral surface of the scraper plate 204 (in [the context of the scraper plate 204]). Figure 4 From the perspective of [the above], this prevents solid waste from accumulating near the waste inlet 104 in the horizontal reactor 101, which would prevent thermophilic bacteria from fully contacting the solid waste and cause only the outer layer of solid waste to be fermented by microorganisms, thus affecting the efficiency of microbial treatment of solid waste. At the same time, during the fermentation process, the four scraper plates 204 rotate to scrape off the solid waste at the bottom of the horizontal reactor 101 and turn it over, thereby preventing the solid waste from clumping.

[0027] like Figures 1-3 As shown, the drive assembly includes a drive motor 301, which is mounted on the upper side of the horizontal reactor 101 via a bracket. The output shaft of the drive motor 301 is equipped with a second rotating shaft 302, which passes through the upper side wall of the horizontal reactor 101 and through the adjacent sealed box 201. Both the second rotating shaft 302 and the adjacent first rotating shaft 202 are equipped with bevel gears, and the bevel gears of the two are meshed with each other. Both bevel gears are located inside the adjacent sealed box 201.

[0028] Taking the drive assembly on the right as an example, the output shaft of the drive motor 301 drives the second shaft 302 to rotate, and the second shaft 302 drives the first shaft 202 to rotate through the bevel gear set.

[0029] like Figure 2 and Figure 4 As shown, heating pipes 401 are installed on both sides of the horizontal reactor 101. The heating pipes 401 pass through the side wall of the horizontal reactor 101 and enter it.

[0030] During the process of adding fecal matter into the horizontal reactor 101 through the fecal matter inlet 104, the heating pipe 401 is connected to the heat source supply pipe (i.e., the hot water supply pipe). In this way, the fecal matter in the horizontal reactor 101 is heated by the heating pipe 401, and the temperature inside the horizontal reactor 101 is maintained at 40°C to 60°C. This not only activates thermophilic bacteria and speeds up the processing of fecal matter, but also reduces the amount of liquid fecal matter in the fecal matter, thereby reducing the volume of fecal matter and facilitating subsequent processing. At the same time, it can also kill insect eggs and pathogens in the fecal matter.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, a stirring frame 501 is fixedly connected to the lower end of the second rotating shaft 302. The cross-section of the stirring frame 501 is cross-shaped. Two stirring frames 501 are staggered. Four pusher plates 601 and four pusher plates 602 are evenly distributed circumferentially between the stirring frame 501 and the adjacent second rotating shaft 302. The pusher plates 602 are located on the upper side of the adjacent pusher plates 601. Both pusher plates 601 and pusher plates 602 are inclined on the adjacent second rotating shaft 302. The pusher plates 601 and pusher plates 602 on the same second rotating shaft 302 are symmetrically distributed in a horizontal figure-eight shape.

[0032] Taking the rotating shaft 302 on the right as an example, the rotation of the rotating shaft 302 drives the stirring frame 501, the four pusher plates 601 and 602 to rotate, stirring the fecal matter in the horizontal reactor 101, so that the fecal matter comes into uniform contact with the thermophilic bacteria, thereby accelerating the speed of thermophilic bacteria treating thermophilic bacteria. At the same time, the four pusher plates 601 rotate to push the fecal matter to the upper left, while the four pusher plates 602 rotate to push the fecal matter to the lower left, thus further ensuring that the fecal matter comes into uniform contact with the thermophilic bacteria.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
