Abstract
Description
Technical Field
[0001] The present application relates to the field of agricultural machinery, and in particular to a fertilizer production and transportation device. Background Art
[0002] Modern large-scale farms produce a large amount of animal manure every day. Farms generally focus on raising a large number of livestock such as pigs, cattle, chickens, etc. These farming activities are designed to meet the market demand for meat and dairy products, but they also produce a large amount of manure. If these manures are not handled properly, they will not only waste potential resources, but may also pollute the environment.
[0003] In the existing technology, farms usually treat manure by discharging it into septic tanks. This method involves placing manure in septic tanks for a long time to reduce the content of harmful substances through natural decomposition. However, manure needs to be placed in septic tanks for a long time to reach the standard of safe treatment, which prolongs the treatment cycle and may also produce odor and release greenhouse gases such as methane during this period, further affecting the environment and climate. Utility Model Content
[0004] To this end, the present application provides a fertilizer production and transportation device to solve the problem of low efficiency in treating manure discharged from farms in the prior art.
[0005] In order to achieve the above objectives, this application provides the following technical solutions:
[0006] A fertilizer production and transportation device comprises a frame convenient for connecting to a transport vehicle and a box connected to the frame, the box comprising a first cavity, a second cavity and a third cavity arranged in sequence, the outer wall of the box is connected to a first pump for pumping feces into the first cavity, the bottom wall of the first cavity is connected to a first heating device for preheating feces, the outer wall of the box is connected to a first discharge port communicating with the first cavity and for discharging water vapor generated by heating feces in the first cavity, the cavity wall of the first cavity is also connected to a second pump for pumping preheated feces in the first cavity into the second cavity, The cavity wall of the second cavity is provided with a crushing device for crushing feces at the output port of the second pump, and the cavity wall of the second cavity is also connected to a third pump for extracting the crushed feces in the second cavity into the third cavity, and the third cavity is connected to a second heating device for heating the crushed feces to a preset temperature to process the feces into biochar, and the outer wall of the box is connected to a second discharge port connected to the third cavity and used to discharge water vapor generated by heating the feces in the third cavity, and the outer wall of the box is connected to a fourth pump connected to the third cavity and used to extract biochar out of the third cavity.
[0007] Optionally, filtering devices for filtering water vapor are provided at both the first discharge port and the second discharge port.
[0008] Optionally, the filtering device is a filter comprising an activated carbon layer.
[0009] Optionally, the first heating device and the second heating device are both a plurality of heating wires arranged at intervals.
[0010] Optionally, the pulverizing device is a pulverizer or a grinder.
[0011] Optionally, there are multiple third pumps, and the output pipes of the multiple third pumps are arranged at equal intervals along the length direction of the third cavity near one end of the third cavity. The box is also connected to a controller, and the multiple third pumps are electrically connected to the controller. The cavity wall of the third cavity is connected to a temperature sensor for detecting the temperature inside the third cavity and electrically connected to the controller. The first pump, the second pump, the fourth pump, the crushing device, the first heating device and the second heating device are all electrically connected to the controller.
[0012] Compared with the prior art, this application has at least the following beneficial effects:
[0013] The feces are pumped to the first chamber through the first pump, where the feces are preheated to remove most of the water. The water vapor generated during the preheating process is discharged through the first discharge port, which reduces the humidity in the chamber and improves the efficiency of subsequent treatment. Subsequently, the preheated feces in the first chamber are pumped to the second chamber through the second pump, where the feces are processed by the crushing device and broken into smaller particles, which reduces the particle size of the feces and increases the specific surface area of the feces, which is convenient for subsequent high-temperature heating to form biochar. In the third chamber, the crushed feces are heated to a preset temperature by the second heating device. During this process, the feces are converted into biomass, and the additional water vapor generated during the heating process is discharged through the second discharge port; finally, the biochar is extracted from the third chamber through the fourth pump and can be directly used for soil improvement or as a renewable energy source. The whole process realizes the efficient treatment and resource utilization of feces, effectively avoids the problem of feces accumulation in the farm, and reduces environmental pollution. Since the entire device is designed to be mobile and can be directly connected to a transport vehicle, it can be easily moved to different work or processing locations as needed to achieve on-site processing and use, thereby enhancing the application flexibility and economic benefits of the equipment.

[0020] refer to Figure 1The present application discloses a fertilizer production and transportation device, comprising a frame 1 that is convenient for connecting to a transport vehicle and a box body 2 connected to the frame 1, the box body 2 comprising a first cavity 21, a second cavity 22 and a third cavity 23 arranged in sequence, the outer wall of the box body 2 is connected to a first pump 3 for pumping feces into the first cavity 21, the bottom wall of the first cavity 21 is connected to a first heating device 212 for preheating feces, the outer wall of the box body 2 is connected to a first discharge port 211 that is connected to the first cavity 21 and is used to discharge water vapor generated by heating feces in the first cavity 21, and the cavity wall of the first cavity 21 is also connected to a first discharge port 211 for pumping the preheated feces in the first cavity 21 into the second cavity 22. The second pump 4 is connected to the wall of the second cavity 22, and a crushing device 221 for crushing feces is provided at the output port of the second pump 4. The wall of the second cavity 22 is also connected to a third pump 5 for extracting the crushed feces in the second cavity 22 into the third cavity 23. The third cavity 23 is connected to a second heating device 232 for heating the crushed feces to a preset temperature to process the feces into biochar. The outer wall of the box body 2 is connected to a second discharge port 231 connected to the third cavity 23 and used to discharge water vapor generated by heating the feces in the third cavity 23. The outer wall of the box body 2 is connected to a fourth pump 6 connected to the third cavity 23 and used to extract biochar out of the third cavity 23.
[0021] The feces are pumped to the first chamber 21 through the first pump 3, where the feces are preheated to remove most of the water. The water vapor generated during the preheating process is discharged through the first discharge port 211, which reduces the humidity in the chamber and improves the efficiency of subsequent processing. Subsequently, the preheated feces in the first chamber 21 are pumped to the second chamber 22 through the second pump 4, where the feces are processed by the crushing device 221 and crushed into smaller particles, which reduces the particle size of the feces and increases the specific surface area of the feces, which is convenient for subsequent high-temperature heating to form biochar. In the third chamber 23, the crushed feces are heated to a preset temperature by the second heating device 232. During this process, the feces are converted into biomass, and the additional water vapor generated during the heating process is discharged through the second discharge port 231; finally, the biochar is extracted from the third chamber 23 through the fourth pump 6 and can be directly used for soil improvement or as a renewable energy source. The whole process realizes the efficient treatment and resource utilization of feces, effectively avoids the problem of feces accumulation in the farm, and reduces environmental pollution. Since the entire device is designed to be mobile and can be directly connected to a transport vehicle, it can be easily moved to different work or processing locations as needed to achieve on-site processing and use, thereby enhancing the application flexibility and economic benefits of the equipment.
[0022] In some embodiments, the first pump 3 , the second pump 4 , the third pump 5 and the fourth pump 6 may be vacuum pumps, sludge pumps or centrifugal pumps, etc.
[0023] Filtering devices for filtering water vapor are provided at the first discharge port 211 and the second discharge port 231. The main function of these filtering devices is to filter and purify the waste gas and impurities contained in the water vapor during the discharge process. When the feces in the first cavity 21 and the third cavity 23 are heated to generate water vapor, these vapors will carry a certain amount of harmful gases and fine particles. Through the filtering devices, these harmful components are effectively removed, thereby purifying the gas discharged into the environment.
[0024] In some embodiments, a valve is provided at the second discharge port 231 to seal the third cavity 23. The main purpose of this is to form a controllable environment inside the third cavity 23. In particular, during the production of biochar, the air in the sealed space can be pumped out by the fourth pump 6 to form a low-oxygen environment. The low-oxygen environment helps reduce the combustion or over-oxidation of feces under high temperature conditions, thereby ensuring the quality and yield of biochar. During the production of biochar, the preset temperature is usually between 300°C and 700°C.
[0025] In some embodiments, the filtration device may be a filter including an activated carbon layer; the filtration device may also be a biofilm, etc.
[0026] The first heating device 212 and the second heating device 232 are both a plurality of heating wires arranged at intervals.
[0027] The pulverizing device 221 is a pulverizer or a grinder.
[0028] There are multiple third pumps 5, and the output pipes of the multiple third pumps 5 are arranged at equal intervals along the length direction of the third cavity 23 near one end of the third cavity 23. The box body 2 is also connected to a controller, and the multiple third pumps 5 are electrically connected to the controller. The cavity wall of the third cavity 23 is connected to a temperature sensor for detecting the temperature in the third cavity 23 and electrically connected to the controller. The first pump 3, the second pump 4, the fourth pump 6, the crushing device 221, the first heating device 212 and the second heating device 232 are all electrically connected to the controller.
[0029] The automatic control of the controller optimizes the entire workflow, so that the above components can automatically adjust the working state according to the preset program or real-time data; the controller automatically adjusts the operation of the first heating device 212 and the second heating device 232 according to the data received from the temperature sensor in the third cavity 23, ensuring that the feces reaches and maintains the preset temperature in the third cavity 23. At the same time, the controller can control the operation of the first pump 3, the second pump 4, the plurality of third pumps 5 and the fourth pump 6 to ensure the effective flow of feces between the cavities; in addition, by arranging the output pipes of the plurality of third pumps 5 at equal intervals along the length direction of the third cavity 23, the feces can be evenly distributed in the third cavity 23, thereby promoting more uniform heating and the formation of biochar.
[0030] In some embodiments, a plurality of hydraulic rods are provided at the bottom of the frame 1, and these hydraulic rods are electrically connected to the controller through components such as solenoid valves. Such a layout allows the hydraulic rods to automatically extend and retract according to the instructions of the controller, thereby adjusting the support for the frame 1; specifically, when the fertilizer production and transportation device is working, the weight of the material in the box 2 will gradually increase, which will exert a greater pressure on the wheels. In order to prevent the wheels from being damaged due to excessive loads, the controller will control the hydraulic rods to extend and support them on the ground, thereby dispersing the load pressure, effectively reducing the pressure on the wheels, and extending the service life of the wheels.
[0031] The front part of the frame 1 is provided with a towing hook, a hook or a pin interface, etc., so as to facilitate connection with a transport vehicle such as an agricultural tractor.
[0032] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
[0033] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
