Description

TECHNICAL FIELD

[0002] With the high-speed development of China's animal husbandry, a large amount of biomass energy is produced, mainly including crop straw or processing waste, poultry manure, household garbage and so on. Most of them are discarded or incinerated as waste, which causes resource waste and environmental pollution.

[0003] In order to solve the above problems, people realize the secondary processing of such energy through technological innovation and application improvement, which realizes the recycling of energy while solving the problem of animal husbandry. The feed of agricultural waste resources is thus born, mainly including green feed, ammoniated feed, protein feed and animal manure feed. However, the common fermentation feed processing raw materials are mostly straw, grass, seeds and high lignin and coarse fiber such as vinasse, rice husk, corn residue and citrus residue. However, some unprocessed coarse materials can cause intestinal burden or cause related diseases, which is not conducive to the development of cattle and sheep breeding industry.

In livestock breeding, the Siraitia grosvenorii residue has a certain application value in ecological feed. After fermentation, the Siraitia grosvenorii residue can be used as full-price ecological fermented feed for cattle and sheep, which can reduce the cost of feed and improve the breeding efficiency.

The materials conveyed by the conveying mechanism 100 enter the stirring box 19 through the feeding groove 17 and are stirred. Specifically, the second motor 12 drives the stirring shaft 15 to rotate, thereby driving the spiral blade 18 to rotate to realize the stirring of the materials in the stirring box 19. The stirred materials enter the second bell-shaped cover 34 after the opening and closing valve 20 is opened. During stirring, the opening and closing valve 20 is in a closed state.

[0046] In the preferred embodiment, the top of the stirring box 19 is fixedly provided with a first bell-shaped cover 14, the bottom of the first bell-shaped cover 14 is fixedly provided with a rotating shaft chuck 16, the stirring shaft 15 passes through the rotating shaft chuck 16, the second motor 12 is fixedly arranged at the top of the first bell-shaped cover 14 and is connected with the stirring shaft 15 through the gearbox 13. The feeding groove 17 is inclined downwardly towards the stirring box 19, so that the material is automatically slid into the stirring box 19 through the inclined groove bottom. The stirring speed is controlled by adjusting the rotating speed of the second motor 12 to adapt to the requirements of different fermentation materials. Meanwhile, the second motor 12 is externally provided with an emergency stop button and is integrated into the control box 28, so that the stirring mechanism 200 can be timely stopped in case of emergency.

[0048] Referring to Figure 1 , Figure 4 and Figure 5 , the fermentation mechanism 300 comprises a fermentation tank 27, the fermentation tank 27 is installed on the second support frame 30, the top side wall of the fermentation tank 27 is provided with a second bell-shaped cover 34 communicating with the fermentation tank 27, the second bell-shaped cover 34 is arranged in the transverse direction, the end of the second bell-shaped cover 34 away from the fermentation tank 27 is fixedly provided with a third motor 32, a feeding screw 35 is arranged in the second bell-shaped cover 34 along the extending direction thereof, one end of the feeding screw 35 passes out of the second bell-shaped cover 34 and is connected with the third motor 32, the top side wall of the end of the second bell-shaped cover 34 away from the fermentation tank 27 is provided with a feeding port for feeding the materials, the feeding port communicates with the pipeline at the bottom of the stirring box 19. The top of the fermentation tank 27 is provided with a hydraulic motor 21 and a motor push rod 22, the motor push rod 22 is connected with the hydraulic motor 21 and the telescopic rod of the motor push rod 22 is driven by the hydraulic motor 21 to move up and down, the telescopic rod of the motor push rod 22 passes into the fermentation tank 27 and is fixedly installed with a top plate 24 at the bottom, the bottom of the fermentation tank 27 is provided with an openable and closable discharge cover plate 29 opposite to the top plate 24, the discharge cover plate 29 is detachably connected with the fermentation tank 27 through bolts.

[0049] The fermentation mechanism 300 has two main power sources: a hydraulic motor 21 and a third motor 32. The hydraulic motor 21 is installed on the side of the motor push rod 22 at the top of the fermentation tank 27. The motor push rod 22 is installed in a pre-reserved slot at the top of the fermentation tank 27. The hydraulic motor 21 causes the extension rod of the motor push rod 22 to extend and retract, which in turn drives the top plate 24 to press the material. The third motor 32 is installed on the far left of the fermentation tank 27 and connected to the second bell-shaped cover 34. Its output shaft is connected to the feeding screw 35 via a coupling 33 to transport the fermentation material. The feeding screw 35 is a hollow spiral, using a left-hand spiral configuration, with a horizontal conveying arrangement from left to right. It is installed inside the connecting pipe between the mixing tank 19 and the fermentation tank 27, and the spiral body is fixed inside the pipe to ensure that the material can smoothly enter and exit the spiral, while avoiding blockages and leaks. The screw allows for easy maintenance and cleaning through bolt disassembly, reducing maintenance difficulty and cleaning work and time. The second caster wheel 31 is fixed to the bottom of the second support frame 30 to enable planar movement of the fermentation mechanism 300. To facilitate real-time monitoring and adjustment of the fermentation environment, the top of the fermentation tank 27 is equipped with an air vent valve 23 and a pressure sensor 26, as well as a water pipe valve 25 and a temperature and humidity sensor 36. The pressure sensor 26 and the temperature and humidity sensor 36 are electrically connected to the control box 28 for observation. The control box 28 is installed on the outer side of the fermentation tank 27.

[0050] During implementation, when valve 20 is opened to discharge material, the third motor 32 drives coupling 33 to rotate. Coupling drives feeding screw 35 to rotate and push material. Adjusting the speed of the third motor 32 to periodically change it within a certain speed range allows for uniform spreading of the mixture at varying distances, completing the material accumulation within fermentation tank 27. Then, the hydraulic motor 21 is driven, causing the telescopic rod of motor push rod 22 to move downwards, using top plate 24 to compact the material.

This process of feeding, stirring, and compaction is repeated multiple times to achieve stratified fermentation of the mixture. During this period, pressure sensor 26 and temperature and humidity sensor 36 monitor the temperature, humidity, and pressure inside the tank in real time for effective regulation. Once sufficient mixture has fermented, the lower discharge cover 29 is opened, and the telescopic rod of motor push rod 22 is driven downwards by hydraulic motor 21, pushing top plate 24 inside the tank for complete material discharge in one go.

[0052] The following is more specific parameter setting of the exemplary embodiment of the utility model.

[0053] The material to be fermented is placed in the discharging groove 10 of conveying mechanism 100 and then enters the material groove 2, and the general conveying standard speed of reference crop is 130m / min, in order to meet the condition, the belt width of conveying belt 9 can be set to 400mm and the running speed is set to 60m / min in the exemplary embodiment;At the same time, considering the material characteristics and conveying efficiency, material groove 2 and sheet metal cover 11 are installed on conveying belt 9, the inclination angle of inclined part of conveying belt 9 is set to 40°, the conveying height is the height from the top end of stirring discharge pipe inlet to the bottom of fermentation tank, which is 5600mm, the horizontal distance is set to 2070mm, and the belt length is set to 11900mm. Through the above settings, the material can be smoothly transported to the feeding groove 17 of stirring mechanism 200 to complete one-time accumulation and layering feeding, and prepare for the next processing.

[0054] When the material is transported to the feeding groove 17 of stirring box 19, in order to complete one-time accumulation and layering discharge 1.23m 3 , the stirring box is set as cylindrical stainless steel tank with diameter 1600mm and height 1000mm;The density of momordica grosvenori residue mixture is generally 200kg / m 3, considering the flowability, viscosity and stirring intensity requirements of the mixture, the size of the stirring tank 19, the blade diameter of the propeller blade 18 is set to 800 mm, and the rotating speed is 60 r / min. When the stirring is completed once, the opening and closing valve 20 at the bottom of the stirring tank 19 is opened, and the mixture enters the feeding cavity of the second bell-shaped cover 34 with the feeding screw 35, preparing for the next step of processing.

[0055] When the mixture enters the feeding cavity of the second bell-shaped cover 34, considering the density and flowability, and in order to meet the requirements of stirring and conveying the material, the shaft length of the feeding screw 35 is set to 1200 mm, the spiral inner tube diameter of the feeding screw 35 is set to 102 mm, the thickness is set to 5 mm, the spiral pitch is set to 280 mm, and the spiral blade diameter is set to 300 mm, and the blade thickness is set to 20 mm. By driving the coupling with the third motor 32, the coupling drives the feeding screw 35 to rotate, which can push the mixture in the second bell-shaped cover 34 out and into the fermentation tank 27. Adjusting the rotating speed of the third motor 32 to periodically change within a certain speed range can achieve uniform distribution of the mixture.

[0056] After the mixture enters the fermentation tank 27, due to the change of pH value during fermentation, the material selected for the fermentation tank 27 needs to have certain strength and rigidity, and also needs to have certain corrosion resistance and heat resistance, as well as safety considerations when producing biological feed. Therefore, the fermentation tank 27 is made of PE plastic material, and the sealing method is roll-formed. The top of the fermentation tank 27 is connected by hot melting after the top plate is loaded. The hot melting connection is resistant to high and low temperatures, and can still maintain good sealing performance under extreme temperature conditions, prevent medium leakage, and has strong corrosion resistance. At the same time, the colloid itself has certain oil and viscosity, which can reduce dry friction or semi-dry friction phenomenon and prolong service life. Moreover, it does not contain any toxic substances and is harmless to biology, and will not pollute the environment of the sealed equipment. Under the treatment of multiple compression of the top plate 24, the volume utilization rate of the fermentation tank 27 can be set to a critical value of 85%, and at the same time, in order to meet the requirement that the single fermentation volume needs to reach 25 m 3The height of the tank body is set to 5000mm, and the diameter of the tank body is set to 2800mm. In order to meet the requirement that the tank body can withstand a pressure of not less than 0.33MPa, the thickness of the tank body is set to 30mm. In addition, considering that the mixture exerts a large pressure on the tank body during operation, and the pressure on the tank bottom is more concentrated, the tank bottom and the discharge cover plate 29 thereof are thickened and set to 60mm. The top of the fermentation tank 27 is provided with a gas hole valve 23 and a water pipe valve 25, and the inner side surface of the top of the tank body of the fermentation tank 27 is further provided with a pressure sensor 26 and a temperature and humidity sensor 36. During the fermentation process, the temperature and humidity are monitored and adjusted in real time. When the temperature and humidity of the sensor change greatly, the following measures can be taken: if the indoor temperature can be adjusted to achieve temperature control effect indoors, a brewing waistband can be additionally installed outdoors for temperature control; when the humidity is low, the water pipe valve 25 can be opened to sprinkle water into the tank to increase the humidity; at the same time, the gas hole valve 23 is arranged at the top of the tank for discharging gas to ensure that the gas pressure in the fermentation tank is within a safe range. After fermentation, the discharge cover plate 29 below the tank body is opened, and the motor push rod 22 at the top of the tank body is used to push the top plate 24 for one-time complete discharge, so that incomplete discharge caused by adhesion of the material in the tank to the tank wall can be avoided.

[0057] In summary, the fermentation device disclosed by the present application can be integrated with a conveying mechanism 100 and a stirring mechanism 200, and can realize automatic feeding and automatic stirring. The fermentation device is provided with a fermentation mechanism 300, which realizes uniform spreading of materials by periodically changing the rotation speed of the feeding screw rod 35, and realizes one-time complete discharge by multiple pressing of the top plate 24, thereby solving the problems of uneven fermentation caused by difficulty in layering during large-batch fermentation, and complex layering fermentation structure, high maintenance difficulty, high energy loss and high resource waste during small-batch fermentation. In addition, the fermentation device is improved in the way of layering and stacking of materials during design, and an outer tank is designed for stirring. Controllable valves are used to control the period of discharging and multi-layer stacking fermentation, which not only ensures the uniformity of material mixing to a great extent, but also saves a lot of cleaning and maintenance costs.
