Description

Technical Field

[0001] The invention relates to the technical field of crushing equipment, and in particular to a raw material processing device for organic fertilizer production. Background Art

[0002] In order to improve the utilization rate of straw, straw that might have been considered waste is converted into a valuable organic fertilizer resource. Through the processing of straw crushing, fermentation and other processes, the rich organic matter, cellulose, hemicellulose and other nutrients contained in it are released and converted into organic fertilizer that is easily absorbed and utilized by plants. This organic fertilizer is not only rich in nitrogen, phosphorus, potassium and other nutrients, but also rich in microorganisms and organic matter, which can significantly improve soil structure, enhance soil fertility, and provide a superior growth environment for the growth of crops.

[0003] In the process of using straw to produce organic fertilizer, the straw is generally crushed. Since the hardness of straws of different types or different positions varies significantly, this hardness difference is directly reflected in the non-uniformity of particles during the crushing process, that is, soft raw materials are easily broken into fine particles, while hard raw materials may remain in large blocks. After the particles of different sizes are mixed, they form different microenvironments in the fermentation pile. Small particles can contact microorganisms faster due to their large surface area, thereby accelerating their decomposition process; on the contrary, large particles are limited in internal microbial activity, resulting in a significant lag in fermentation speed. This difference in fermentation speed not only prolongs the overall production cycle, but may also affect the maturity of the organic fertilizer due to incomplete fermentation. Summary of the invention

[0004] When using existing crushing devices to crush straw, there are obvious differences in the hardness of straw at different positions or different types of straw. For example, the hardness at the tip of corn straw is less than the hardness near the root system. When the straw is put into the crushing device, there are differences in the size of the crushed particles. In the subsequent fermentation process, the rate at which large particles are decomposed is lower than the rate at which small particles are decomposed, thereby affecting the efficiency of preparing organic fertilizer.

[0024] like Figures 1 to 3As shown, an embodiment of the present invention provides a raw material processing device for organic fertilizer production, which includes a mounting cylinder 110, a crushing cylinder 120, a stirring module and a regulating module.

[0025] The installation cylinder 110 has a main fermentation chamber inside.

[0026] Specifically, an opening is provided at the upper end of the mounting barrel 110, and the opening can connect the external environment with the main fermentation chamber. An observation window connecting the external environment with the main fermentation chamber is provided on the side wall of the mounting barrel 110. A glass plate is provided on the side wall of the mounting barrel 110, and the glass plate can seal the observation window to ensure that the staff can observe the conditions in the main fermentation chamber in time.

[0027] The crushing barrel 120 is hollow inside and is arranged in the main fermentation chamber; a feeding port connecting the external environment and the internal environment is arranged on the crushing barrel 120; a plurality of discharge holes 130 are arranged at the bottom of the crushing barrel 120; a plurality of sieve plates 140 are arranged inside the crushing barrel 120, and the plurality of sieve plates 140 can divide the interior of the crushing barrel 120 into a plurality of pre-fermentation chambers, and each sieve plate 140 is provided with sieve holes 141, and the sieve holes 141 on the sieve plates 140 gradually decrease from top to bottom, and the aperture of the sieve holes 141 on the lowest sieve plate 140 is larger than the aperture of the discharge hole 130; a first blocking plate is arranged on each sieve plate 140, and the first blocking plate can block the sieve hole 141; a second blocking plate is arranged at the lower end of the crushing barrel 120, and the second blocking plate can block the discharge hole 130.

[0028] Specifically, the crushing barrel 120 is hollow inside, and the crushing barrel 120 is fixedly arranged in the main fermentation chamber. The upper end of the crushing barrel 120 is the same size as the opening of the upper end of the mounting barrel 110. At this time, objects in the external environment cannot enter the main fermentation chamber through the opening of the upper end of the mounting barrel 110. The length of the crushing barrel 120 in the vertical direction is less than the length of the mounting barrel 110 in the vertical direction, and there is a gap between the lower end of the crushing barrel 120 and the lower end surface of the mounting barrel 110. The crushing barrel 120 is provided with a feeding port connecting the external environment and the internal environment, and the straw can enter the crushing barrel 120 through the feeding port. The bottom of the crushing barrel 120 is provided with a plurality of discharge holes 130, and the straw in the crushing barrel 120 can enter the main fermentation chamber through the discharge holes 130. According to the setting of the discharge holes 130, the straw particles can enter the main fermentation chamber only when the particle size of the straw particles is smaller than the aperture of the discharge holes 130. A plurality of sieve plates 140 are arranged inside the crushing barrel 120. The plurality of sieve plates 140 can divide the interior of the crushing barrel 120 into a plurality of pre-fermentation chambers. According to the arrangement of the positions of the plurality of sieve plates 140, the plurality of pre-fermentation chambers can evenly divide the internal space of the crushing barrel 120, so that the space size of each pre-fermentation chamber is the same. A sieve hole 141 is arranged on each sieve plate 140. On the plurality of sieve plates 140 in the vertical direction, the aperture of the sieve hole 141 gradually decreases, wherein the aperture of the sieve hole 141 on the bottom sieve plate 140 is larger than the aperture of the discharge hole 130. Accordingly, the diameter of the straw particles entering the main fermentation chamber is in the minimum state. In the vertical direction, the diameter of the straw particles in the plurality of pre-fermentation chambers from top to bottom is in a gradually decreasing state.

[0029] Furthermore, each sieve plate 140 is provided with a first blocking plate, which is coaxially rotatably connected to the sieve plate, and a leakage hole of the same size as the sieve hole 141 is set on the first blocking plate. When the first blocking plate rotates, the first blocking plate can block the sieve hole 141; a second blocking plate is provided at the lower end of the crushing barrel 120, and the second blocking plate is coaxially rotatably connected to the lower end of the crushing barrel 120. A leakage hole of the same size as the discharge hole 130 is set on the second blocking plate. When the second blocking plate rotates, the second blocking plate can block the discharge hole 130. Specifically, when the amount of straw particles entering the main fermentation chamber reaches a certain level, each first sealing plate blocks a sieve hole 141 on the sieve plate 140, and the second sealing plate blocks the discharge hole 130, ensuring that the straw particles in the pre-fermentation chamber no longer fall, so that the straw particles in the pre-fermentation chamber no longer enter the main fermentation chamber. At this time, the straw particles in the main fermentation chamber begin to ferment. When the straw particles in the main fermentation chamber are fermenting, the straw particles in the pre-fermentation chamber begin to pre-ferment.

[0030] The stirring module includes a turning unit and a plurality of crushing units, each crushing unit can crush the material in a pre-fermentation chamber; the turning unit is used to turn the material in the main fermentation chamber.

[0031] Specifically, each crushing unit can crush the material in a pre-fermentation chamber. The straw is first put into the pre-fermentation chamber at the top. Under the action of the crushing unit, the straw particles gradually become smaller. After being crushed by multiple crushing units, when the size of the straw particles is smaller than the aperture of the discharge hole 130, the straw particles can enter the main fermentation chamber. After the straw particles in the main fermentation chamber begin to ferment for a period of time, the straw particles are easy to compact in the main fermentation chamber. The turning unit turns the materials in the main fermentation chamber from time to time to ensure that the straw particles can be fermented smoothly in the main fermentation chamber. At the same time, when the straw particles in the main fermentation chamber are fermenting, the materials in the pre-fermentation chamber begin to ferment at the same time. Since the size of the straw particles in the pre-fermentation chamber is larger than that of the straw particles in the main fermentation chamber, the fermentation speed of the straw particles in the main fermentation chamber is greater than that in the pre-fermentation chamber. After the fermentation of the straw particles in the main fermentation chamber is completed, the straw particles in the pre-fermentation chamber are not fully fermented. However, the hardness of the straw particles is reduced after pre-fermentation, making it easier to break the straw particles in the pre-fermentation chamber. Figure 3 As shown, after the straw particles fermented in the pre-fermentation chamber enter the main fermentation chamber, the fermentation time of the straw particles in the main fermentation chamber is reduced, thereby improving the efficiency of producing organic fertilizer.

[0032] The control module can control the environment in the main fermentation chamber.

[0033] Specifically, when the straw particles in the main fermentation chamber begin to ferment, the fermentation of the straw particles requires suitable conditions such as humidity, temperature and oxygen content. The control module can control the environment in the main fermentation chamber to be an environment suitable for the fermentation of straw particles, ensuring that the straw particles can be fermented smoothly in the main fermentation chamber.

[0034] The present invention provides a raw material processing device for producing organic fertilizer. During the process of using straw to produce organic fertilizer, the straw is put into a crushing barrel 120. A plurality of sieve plates 140 are installed inside the crushing barrel 120. The plurality of sieve plates 140 divide the crushing barrel 120 into a plurality of pre-fermentation chambers. The straw is first put into the uppermost pre-fermentation chamber. As the plurality of crushing units crush the straw, the straw particles in different pre-fermentation chambers have different sizes. After the plurality of crushing units crush the straw, some particles can enter the main fermentation chamber through the discharge hole 130. In this state, straw particles are retained in both the main fermentation chamber and the plurality of pre-fermentation chambers. When the amount of straw particles in the main fermentation chamber reaches a certain level, each first blocking plate blocks a sieve hole 141 on the sieve plate 140, and the second The sealing plate seals the discharge hole 130; the straw in the main fermentation chamber enters the fermentation state, and the turning unit can turn the material in the main fermentation chamber to ensure that the material in the main fermentation chamber can be fully fermented. Correspondingly, the straw particles retained in the pre-fermentation chamber enter the pre-fermentation stage. When the turning unit turns the material in the main fermentation chamber, the crushing unit performs crushing and stirring on the material in the pre-fermentation chamber; the control module can adjust the environment in the main fermentation chamber to ensure that the environment in the main fermentation chamber is suitable for fermentation. Through the setting of the pre-fermentation chamber, the straw has been pre-fermented to a certain extent before entering the main fermentation chamber. The straw after pre-fermentation is easier to be crushed, thereby improving the efficiency of crushing the straw into particles of the same size, while reducing the time of subsequent fermentation, thereby improving the efficiency of producing organic fertilizer.

[0035] In one embodiment, the control module includes a controller, a first regulating unit and a second regulating unit. The controller can control the first regulating unit to adjust the humidity in the main fermentation chamber; the controller can also control the second regulating unit to adjust the oxygen supply in the main fermentation chamber.

[0036] Specifically, when straw particles are fermented to prepare organic fertilizer, the straw particles will undergo aerobic fermentation and anaerobic fermentation. The humidity of the straw particles during aerobic fermentation and anaerobic fermentation is generally between 60% and 70%. Since the humidity of the straw before being put into the pre-fermentation chamber is uncertain, in order to ensure that the crushed straw particles can be suitable for fermentation, the controller can control the first regulating unit to adjust the humidity in the main fermentation chamber. When the first sealing plate does not seal the sieve hole 141 and the second sieve plate 140 does not seal the discharge hole 130, the main fermentation chamber and the pre-fermentation chamber are in a state of interconnection. When the first regulating unit adjusts the humidity in the main fermentation chamber, the humidity in the pre-fermentation chamber is the same as the humidity in the main fermentation chamber, ensuring that the straw particles in the pre-fermentation chamber and the straw particles in the main fermentation chamber can be fermented at the same time.

[0037] Furthermore, the controller can also control the second regulating unit to adjust the oxygen supply in the main fermentation chamber. When using straw particles to prepare organic fertilizer, the straw particles need to undergo aerobic fermentation and anaerobic fermentation. When the straw particles are undergoing aerobic fermentation in the main fermentation chamber, the second regulating unit can provide sufficient oxygen to the main fermentation chamber; when the straw particles are undergoing anaerobically fermentation in the main fermentation chamber, the second regulating unit can extract the oxygen in the main fermentation chamber from the main fermentation chamber, so that the straw particles in the main fermentation chamber can be successfully prepared as organic fertilizer.

[0038] Furthermore, the second regulating unit mainly regulates the oxygen content in the main fermentation chamber. Since the particle size in the pre-fermentation chamber is larger than the particle size in the main fermentation chamber, when the aerobic fermentation of the material in the main fermentation chamber is completed, the aerobic fermentation of the material in the pre-fermentation chamber will not be completed. At this time, the second regulating unit only needs to regulate the oxygen content in the main fermentation chamber, so that aerobic fermentation continues in the pre-fermentation chamber.

[0039] In one embodiment, the controller is configured as follows: when the humidity in the main fermentation chamber is lower than a first preset value, the controller controls the first regulating unit to adjust the humidity in the main fermentation chamber; wherein the first preset value is the minimum humidity required for fermentation of straw materials.

[0040] Specifically, when straw particles are fermented to prepare organic fertilizer, the straw particles will undergo aerobic fermentation and anaerobic fermentation. The humidity of the straw particles during aerobic fermentation and anaerobic fermentation is generally between 60% and 70%. The first preset value is set to a humidity of 60%. When the humidity in the main fermentation chamber is lower than 60%, the fermentation of the straw particles in the main fermentation chamber is restricted. At this time, the controller controls the first regulating unit to adjust the humidity in the main fermentation chamber. Correspondingly, the humidity in the pre-fermentation chamber can be adjusted at the same time, so that the humidity in the pre-fermentation chamber can also be suitable for the fermentation of straw particles.

[0041] In one embodiment, a humidity sensor is provided in the main fermentation chamber, and the humidity sensor can monitor the humidity in the main fermentation chamber in real time, and the humidity sensor can transmit the monitored data to the controller.

[0042] Specifically, the humidity sensor is arranged in the main fermentation chamber, and the temperature sensor can monitor the humidity in the main fermentation chamber in real time. When the straw particles enter the main fermentation chamber, the controller can timely control the first adjustment unit to adjust the humidity in the main fermentation chamber. When the first adjustment unit adjusts the humidity in the main fermentation chamber, the humidity in the pre-fermentation chamber can be adjusted at the same time to ensure that the humidity in the pre-fermentation chamber is also suitable for the fermentation of straw particles.

[0043] In one embodiment, the first regulating unit includes a water spray pipe, which can spray water into the main fermentation chamber through the crushing barrel 120. When the water spray pipe sprays water into the main fermentation chamber, the water sprayed from the water spray pipe passes through the pre-fermentation chamber. Accordingly, when the humidity in the main fermentation chamber is regulated, the humidity in the pre-fermentation chamber can be adjusted at the same time.

[0044] In one of the embodiments, the controller can also be configured as follows: when the material in the main fermentation chamber is undergoing aerobic fermentation, the controller can control the second regulating unit to continuously provide oxygen to the main fermentation chamber; when the material in the main fermentation chamber is undergoing anaerobic fermentation, the controller can control the second regulating unit to extract oxygen from the main fermentation chamber.

[0045] Specifically, when using straw particles to prepare organic fertilizer, the straw particles need to undergo aerobic fermentation and anaerobic fermentation. When the straw particles undergo aerobic fermentation in the main fermentation chamber, the controller controls the second regulating unit to provide sufficient oxygen to the main fermentation chamber; when the straw particles undergo anaerobic fermentation in the main fermentation chamber, the controller controls the second regulating unit to extract the oxygen in the main fermentation chamber from the main fermentation chamber, so that the straw particles in the main fermentation chamber can be smoothly prepared into organic fertilizer. For example, the second regulating unit is an exhaust fan. When the straw particles in the main fermentation chamber undergo aerobic fermentation, the exhaust fan extracts gas into the main fermentation chamber to ensure that there is sufficient oxygen in the main fermentation chamber. On the contrary, when the straw particles in the main fermentation chamber undergo anaerobic fermentation, the exhaust fan extracts the oxygen in the main fermentation chamber from the main fermentation chamber to ensure that the main fermentation chamber is in an oxygen-deficient state.

[0046] In one embodiment, a regulating port connecting the external environment and the main fermentation chamber is provided on the side wall of the mounting cylinder 110; the second regulating unit includes at least an exhaust fan and a control valve, the exhaust fan is arranged at the regulating port, and a control valve is arranged on the regulating port, the controller can adjust the conduction state of the control valve, and the controller can also control the exhaust direction of the exhaust fan.

[0047] Specifically, the adjustment port on the side wall of the mounting cylinder 110 is arranged at the lower end of the mounting cylinder 110, and the exhaust fan is arranged outside the main fermentation chamber to prevent straw particles from entering the exhaust fan. The control valve is an electrically controlled valve, and the controller can adjust the conduction state of the control valve through an electrical signal. When the controller controls the exhaust direction of the exhaust fan, the controller changes the rotation direction of the fan blades inside the exhaust fan.

[0048] In one of the embodiments, a gas detection module is provided in the main fermentation chamber, and the gas detection module can detect the gas components generated in the main fermentation chamber. The controller can adjust the conduction state of the control valve according to the data of the gas detection module. The controller can also adjust the exhaust direction of the exhaust fan according to the data of the gas detection module.

[0049] Specifically, when the straw particles are fermented in the main fermentation chamber, the straw particles can produce specific gases when they are aerobically fermented in the main fermentation chamber. Correspondingly, when the straw particles are anaerobically fermented in the main fermentation chamber, they can produce specific gases. The gas detection module can detect the gases that can be produced when the straw particles are fermented. According to the data detected by the gas detection module, the fermentation state of the straw particles in the main fermentation chamber can be accurately judged, so that the air can accurately adjust the oxygen content in the main fermentation chamber.

[0050] In one of the embodiments, the gas detection module can detect the amount of carbon dioxide produced in the main fermentation chamber per unit time, and the gas detection module can also detect the oxygen concentration in the main fermentation chamber; when the amount of carbon dioxide produced in the main fermentation chamber per unit time is lower than a second preset value, the controller adjusts the exhaust fan to extract the gas in the main fermentation chamber, and when the oxygen concentration in the main fermentation chamber is lower than a third preset value, the controller adjusts the control valve to a blocked state.

[0051] Specifically, the main gas produced when the straw particles are aerobic fermented in the main fermentation chamber is carbon dioxide. The gas detection module can detect the amount of carbon dioxide produced in the main fermentation chamber per unit time. According to the data obtained by the gas detection module, the controller can determine the degree of aerobic fermentation of the straw particles in the main fermentation chamber. When the amount of carbon dioxide produced in the main fermentation chamber per unit time is lower than a certain value, the controller can adjust the oxygen concentration in the main fermentation chamber. At the same time, the gas detection module can also detect the oxygen concentration in the main fermentation chamber. When the amount of carbon dioxide produced in the main fermentation chamber per unit time is lower than a second preset value, wherein the second preset value is a manually set value. For example, in the early stage of aerobic fermentation of the straw particles in the main fermentation chamber, the amount of carbon dioxide produced in the main fermentation chamber per unit time is 0.2 cubic meters. In the middle stage of aerobic fermentation of the straw particles in the main fermentation chamber, the amount of carbon dioxide produced in the main fermentation chamber per unit time is 0.2 cubic meters. The amount of carbon dioxide produced in the main fermentation chamber per unit time is 0.1 cubic meter. At this time, the second preset value is set to 0.1 cubic meter. When the amount of carbon dioxide produced in the main fermentation chamber per unit time is less than 0.1 cubic meter, the controller adjusts the exhaust fan to extract the gas in the main fermentation chamber. As the oxygen content in the main fermentation chamber gradually decreases, the aerobic fermentation of the straw particles in the main fermentation chamber gradually ends. When the oxygen concentration in the main fermentation chamber is lower than the third preset value, the third preset value is an artificially set value. For example, when the oxygen concentration is reduced to below about 10% to 15%, some aerobic bacteria may enter a dormant state or significantly slow down their metabolic activities. The third preset value is set to 10%. When the oxygen concentration in the main fermentation chamber is lower than 10%, the controller adjusts the control valve to be in a blocked state, so that the main fermentation chamber is in a relatively oxygen-deficient environment.

[0052] In one embodiment, when the oxygen concentration in the main fermentation chamber is lower than a third preset value, anaerobic bacteria are added into the main fermentation chamber.

[0053] Specifically, when the straw particles are aerobically fermented in the main fermentation chamber, the main fermentation chamber is in an oxygen-rich environment, and the anaerobic bacteria in the straw particles may be in a dormant state or in a state in which their metabolic activity is significantly slowed. As the oxygen concentration in the main fermentation chamber decreases, it takes a period of time for the anaerobic bacteria in a dormant state or in a state in which their metabolic activity is significantly slowed to recover their original vitality. At this time, by adding anaerobic bacteria to the main fermentation chamber, the straw particles in the main fermentation chamber can quickly enter the anaerobic fermentation state, thereby reducing the fermentation time of the straw particles in the main fermentation chamber.

[0054] In one of the embodiments, the crushing module further comprises a driving unit, and the driving unit is used to drive the turning unit and the plurality of crushing units simultaneously.

[0055] Specifically, the driving unit includes a driving motor 150 and a driving shaft. The driving shaft is arranged through the mounting cylinder 110 and the crushing cylinder 120. The driving motor 150 is installed on the mounting cylinder 110. The driving motor 150 is used to drive the driving shaft to rotate. The crushing unit includes a plurality of crushing knives, which are fixedly arranged on the driving shaft, and the plurality of crushing knives are evenly distributed around the circumference of the driving shaft; the flipping unit includes a plurality of flipping rods, which are fixedly arranged on the driving shaft, and the plurality of flipping rods are evenly distributed around the circumference of the driving shaft.
