Description

Technical Field

[0001] This utility model relates to the field of brewing yeast waste residue treatment technology, specifically to a continuous fermentation device for organic fertilizer based on brewing yeast waste residue. Background Technology

[0002] Yeast starter is made by introducing Aspergillus conidia into strongly cooked white rice, then keeping it warm. Mycelia will then grow abundantly on the rice grains; this is yeast starter. The amylase produced by Aspergillus saccharifies the starch in the rice. Therefore, it has been used alongside malt as a raw sugar for making wine, sweet wine, and soy sauce since ancient times. After fermentation, yeast starter residue is produced.

[0003] The accumulation of yeast residue is prone to decay, which leads to environmental pollution. Yeast residue is rich in protein, amino acids, vitamins and microbial flora. Therefore, people try to ferment yeast residue into organic fertilizer through secondary fermentation for recycling. However, traditional composting, which is done through static composting, has problems such as long fermentation cycle, uneven turning, and difficulty in controlling temperature and humidity.

[0004] Therefore, it is necessary to propose a continuous fermentation device for organic fertilizer based on brewing yeast residue to solve the above problems. Utility Model Content

Through the cooperation between the internal parts of the turning mechanism, the turning blades and cutting blades can evenly turn the yeast residue inside the main body of the fermentation device during the fermentation process, so as to stabilize the temperature of the yeast residue during fermentation. Through the cooperation between the internal parts of the spraying mechanism, the temperature and humidity of the yeast residue during fermentation can be easily controlled, and the fermentation cycle of the yeast residue can be shortened. This solves the problems of long fermentation cycle and uneven turning in the traditional composting process using static composting.

The output end of the servo motor is rotatably connected to a support rod via a coupling and is rotatably connected to the inside of the box cover. A hydraulic telescopic rod is mechanically fixed to the bottom end of the support rod. A flipping blade is sleeved and fixed to the outer wall of the hydraulic telescopic rod. A cutting blade is rotatably connected to the bottom end of the box cover and is sleeved with the outer wall of the flipping blade.

[0008] The spraying mechanism includes a centrifugal fan, which is bolted to the right side of the fermentation device body. The aeration pipe of the centrifugal fan extends into the interior of the fermentation device body. A water tank is bolted to the left side of the fermentation device body. A filter plate is mechanically installed inside the fermentation device body. A diverter ring is mechanically fixed inside the tank cover. A spray nozzle is threaded to the bottom of the diverter ring. Water pipes are installed on one side of the outer wall of the diverter ring and the top of the water tank. Multiple water pipes are connected by clamps.

[0009] Preferably, the flipping mechanism further includes a transmission gear, which is sleeved and fixed to the outer wall of the support rod. The inside of the box cover is rotatably connected to a connecting gear via a bearing and is located at one end of the transmission gear. A toothed ring is connected to the side of the connecting gear away from the transmission gear and is mechanically fixed to the top of the cutting blade and rotatably connected to the inside of the box cover.

[0010] Preferably, the bottom of the fermentation device body is provided with a discharge port that matches the sealing ring, and sealing rings are provided at the connection between the box cover and the fermentation device body, and between the fermentation device body and the sealing ring.

[0011] Preferably, the surface of the filter plate is provided with small water filtration holes, and a drainage channel communicating with the water tank is provided between the bottom end of the filter plate and the inner wall of the fermentation device body. A water pump for driving the water pipe is installed at the top of the water tank.

[0012] Preferably, the support rod is equipped with a hydraulic pump that drives the hydraulic telescopic rod to extend and retract, and the outer wall of the hydraulic telescopic rod is equipped with multiple temperature sensors that are connected to the controller signal. The inside of the diversion ring is provided with an annular water flow channel that communicates with the water pipe, and multiple water distribution channels that communicate with the spray nozzles are provided below the annular water flow channel.

[0013] Preferably, the inside of the box cover is provided with a transmission groove that matches the transmission gear, the connecting gear, and the gear ring, and the transmission gear, the connecting gear, and the gear ring mesh with each other through the tooth groove.

[0016] Multiple temperature sensors are installed on the outer wall of the hydraulic telescopic rod and connected to the controller. When the temperature sensors detect excessively high temperatures, they transmit a signal to the controller. Upon receiving the signal, the controller activates the water pump, causing the leachate in the water tank to flow into the diversion ring through the water pipe. After being diverted in the diversion ring, the leachate is fed into the spray nozzles, which spray the yeast residue inside the fermentation unit. This maintains the yeast residue in a suitable temperature and humidity environment, significantly shortening the fermentation cycle. The leachate flows downwards under gravity and contacts the filter plate, which filters it into the diversion trough and then returns it to the water tank for recycling. Simultaneously, the controller controls the centrifugal fan and aeration pipes to provide ventilation and oxygen, preventing ozone generation inside the fermentation unit. Finally, the fermented yeast residue is discharged from the fermentation unit by opening the sealing ring, further shortening the fermentation cycle and ensuring stable fermentation.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown, the continuous fermentation device for organic fertilizer based on yeast residue includes a fermentation device body 1. The top of the fermentation device body 1 is sealed with a box cover 101 by bolts. The top of the box cover 101 is equipped with a flipping mechanism 2, which penetrates the box cover 101 into the interior of the fermentation device body 1. Spraying mechanisms 3 are installed on both sides of the outer wall of the fermentation device body 1 and the box cover 101, which penetrate into the interior of the fermentation device body 1 and the box cover 101. The bottom of the fermentation device body 1 is connected with a sealing ring 4 by a threaded seal.

[0027] The flipping mechanism 2 includes a servo motor 201, which is fixed to the top of the box cover 101 by bolts. The output end of the servo motor 201 is rotatably connected to a support rod 202 via a coupling and is rotatably connected to the inside of the box cover 101. A hydraulic telescopic rod 203 is mechanically fixed to the bottom end of the support rod 202. A flipping blade 204 is sleeved and fixed to the outer wall of the hydraulic telescopic rod 203. A cutting blade 208 is rotatably connected to the bottom end of the box cover 101 and is sleeved with the outer wall of the flipping blade 204.

[0028] The spraying mechanism 3 includes a centrifugal fan 301, which is fixed to the right side of the fermentation device body 1 by bolts. The aeration pipe of the centrifugal fan 301 extends into the interior of the fermentation device body 1. A water tank 302 is fixed to the left side of the fermentation device body 1 by bolts. A filter plate 303 is mechanically installed inside the fermentation device body 1. A diverter ring 304 is mechanically fixed inside the tank cover 101. A spray nozzle 306 is threaded to the bottom end of the diverter ring 304. A water pipe 305 is installed on one side of the outer wall of the diverter ring 304 and the top of the water tank 302. Multiple water pipes 305 are connected by clamps.

[0029] Through the cooperation between the internal parts of the turning mechanism 2, the turning blade 204 and the cutting blade 208 can evenly turn the yeast residue inside the fermentation device body 1 during the fermentation process, so that the temperature of the yeast residue during fermentation is stable. Through the cooperation between the internal parts of the spraying mechanism 3, the temperature and humidity of the yeast residue during fermentation can be easily controlled, and the fermentation cycle of the yeast residue can be shortened.

[0030] Refer to the instruction manual appendix Figure 1-5 The turning mechanism 2 also includes a transmission gear 205, which is sleeved and fixed on the outer wall of the support rod 202. The inside of the box cover 101 is rotatably connected to a connecting gear 206 via a bearing, and is located at one end of the transmission gear 205. A toothed ring 207 is connected to the side of the connecting gear 206 away from the transmission gear 205, and is mechanically fixed to the top of the cutting blade 208 and rotatably connected to the inside of the box cover 101. Through the mutual cooperation between the internal parts of the turning mechanism 2, the turning blade 204 and the cutting blade 208 rotate in opposite directions, so as to better cut and turn the yeast residue inside the fermentation device body 1.

[0031] The bottom of the fermentation device body 1 is provided with a discharge port that matches the sealing ring 4. Sealing rings are provided at the connection between the box cover 101 and the fermentation device body 1, and between the fermentation device body 1 and the sealing ring 4. A controller with a microcontroller as its core is installed on the surface of the box cover 101. The inner lining of the fermentation device body 1 is made of corrosion-resistant stainless steel, and the outer wall is covered with polyurethane insulation material. The use of corrosion-resistant stainless steel for the inner lining of the fermentation device body 1 and polyurethane insulation material for the outer wall helps to maintain a stable temperature inside the fermentation device body 1, preventing the heat of fermentation from dissipating rapidly and thus shortening the fermentation cycle.

[0032] The surface of the filter plate 303 is provided with small water filtration holes, and a drainage channel communicating with the water tank 302 is provided between the bottom end of the filter plate 303 and the inner wall of the fermentation device body 1. A water pump driving the water pipe 305 is installed at the top of the water tank 302. The small water filtration holes on the surface of the filter plate 303 and the drainage channel communicating with the water tank 302 between the bottom end of the filter plate 303 and the inner wall of the fermentation device body 1 facilitate the recycling of water generated during the pretreatment of yeast residue before fermentation, thereby saving resources and reducing the operating cost of the fermentation device body 1.

[0033] The support rod 202 houses a hydraulic pump that drives the hydraulic telescopic rod 203 to extend and retract. Multiple temperature sensors are installed on the outer wall of the hydraulic telescopic rod 203 and are connected to the controller signal. The diversion ring 304 has an annular water channel connected to the water pipe 305 inside, and multiple water distribution channels connected to the spray nozzles 306 are located below the annular water channel. The hydraulic pump inside the support rod 202 drives the hydraulic telescopic rod 203 to extend and retract, and the multiple temperature sensors on the outer wall of the hydraulic telescopic rod 203 facilitate adjustment of the turning depth of the turning blades 204 within the fermentation device body 1. This adjustment of the turning depth can be based on the accumulation height of the yeast residue, improving the turning effect.

[0034] The inside of the cover 101 is provided with a transmission groove that matches the transmission gear 205, the connecting gear 206, and the gear ring 207. The transmission gear 205, the connecting gear 206, and the gear ring 207 mesh with each other through the tooth groove. The turning blade 204 and the cutting blade 208 are spirally distributed around the outer wall of the hydraulic telescopic rod 203, and the spiral directions of the turning blade 204 and the cutting blade 208 are opposite. By the turning blade 204 and the cutting blade 208 spirally distributed around the outer wall of the hydraulic telescopic rod 203, and the spiral directions of the turning blade 204 and the cutting blade 208 are opposite, it is convenient for the turning blade 204 and the cutting blade 208 to rotate in opposite directions, so as to better cut and turn the yeast waste inside the fermentation device body 1.

[0035] The working principle of this practical application is as follows:

[0036] After pretreatment, the yeast residue is poured into the fermentation device body 1 and the lid 101 is closed. The hydraulic telescopic rod 203 is extended and retracted by the controller. The depth is adjusted according to the accumulation height of the yeast residue inside the fermentation device body 1. The servo motor 201 is started, which drives the support rod 202 to rotate. The rotation of the support rod 202 drives the hydraulic telescopic rod 203 to rotate. The rotation of the hydraulic telescopic rod 203 drives the turning blade 204 to rotate. The turning blade 204 rotates and turns the yeast residue inside the fermentation device body 1 at a uniform speed to ensure stability during the fermentation process. At the same time, the rotation of the support rod 202 drives the transmission gear 205 to rotate. The rotation of the transmission gear 205 drives the connecting gear 206 to rotate. The rotation of the connecting gear 206 drives the gear ring 207 to rotate. The rotation of the gear ring 207 drives the cutting blade 208 connected at the bottom to rotate. The rotation of the cutting blade 208 cuts and scrapes off the yeast residue adhering to the inner wall of the fermentation device body 1, thus turning and fermenting the yeast residue and improving the stability of the temperature rise during yeast fermentation.

[0037] Multiple temperature sensors are installed on the outer wall of the hydraulic telescopic rod 203 and are connected to the controller signal. This allows the temperature sensors to transmit a signal to the controller when they detect an excessively high temperature. Upon receiving the signal, the controller activates the water pump, causing the leachate in the water tank 302 to flow through the water pipe 305 into the diversion ring 304. After being diverted in the diversion ring 304, the leachate is then fed into the spray nozzles 306, which spray the yeast residue inside the fermentation unit 1, maintaining the yeast residue within the fermentation unit 1 at a suitable temperature and humidity. Under certain conditions, the fermentation cycle of the yeast residue is greatly shortened. The leachate flows downward under gravity and comes into contact with the filter plate 303. The leachate is filtered through the filter plate 303 into the diversion trough and then flows back into the water tank 302 for recycling. At the same time, the controller controls the centrifugal fan 301 and the aeration pipe to ventilate and supply oxygen, preventing the generation of ozone inside the fermentation device body 1. Finally, the fermented yeast residue can be discharged from the fermentation device body 1 by opening the sealing ring 4, which greatly shortens the fermentation cycle of the yeast residue and ensures the stability of the fermentation.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
