Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composting, in particular to a self-moving precise synergistic regulation intelligent composting reactor. BACKGROUND

[0002] With the continuous expansion of livestock and poultry breeding scale, the amount of livestock and poultry manure is rapidly increasing. Composting is a common way to convert livestock and poultry manure into organic fertilizer, which realizes the resource utilization of livestock and poultry manure. Among them, the aerobic composting technology is biodegradable, which can decompose and convert the organic waste in livestock and poultry manure into stable humus substances under aerobic conditions through the metabolic activity of microorganisms.

[0003] The composting reactor is a device specially used for composting. The composting reactor is usually an aerobic zone. The oxygen concentration of the aerobic zone needs to be controlled during the composting process. In the related technology, a threshold value of the oxygen concentration of the aerobic zone is set. During the composting process, the oxygen concentration in the aerobic zone is detected, and the aeration amount of the aerobic zone is controlled according to the detection value of the oxygen concentration and the set threshold value, until the detection value of the oxygen concentration of the aerobic zone is consistent with the set threshold value. Although the regulation of the oxygen concentration of the aerobic zone is realized, the set threshold value of the oxygen concentration is a fixed value, which has a large difference with the oxygen concentration required by each fermentation stage, resulting in an unsatisfactory fermentation effect of the composting material. In addition, the reactor is mostly in a strong aeration state (to maintain an aerobic state), lacks a pretreatment stage of the composting raw material, and the strong aeration in the later stage of composting (cooling and maturation stage) will cause a large loss of nutrients, which is not conducive to achieving a better humification level, and the high aeration amount used in the whole composting process also leads to high operating cost and energy consumption.

[0004] Therefore, how to solve the problems of the composting reactor in the related technology, such as unsatisfactory fermentation effect of the material, low humification degree, large nutrient loss and high energy consumption, has become an important technical problem to be solved by the technical personnel in the field.

[0072] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0073] The following is combined with Figures 1 to 8 This invention describes a self-propelled, precisely coordinated, and intelligent composting reactor.

[0074] like Figures 1 to 8 As shown, the self-propelled, precise, and collaboratively controlled intelligent composting reactor provided in this embodiment of the invention includes a reactor body, an aeration device, an oxygen concentration sensor, a normal oxygen zone temperature sensor 5, a normal oxygen zone moisture sensor 23, and a control device 6.

[0075] Specifically, the reactor body has a low-oxygen zone 1, a normal-oxygen zone 2, and an ultra-low-oxygen zone 3 distributed sequentially inside. Both the low-oxygen zone 1 and the ultra-low-oxygen zone 3 are connected to the normal-oxygen zone 2. Materials in the low-oxygen zone 1 can move to the normal-oxygen zone 2, and materials in the normal-oxygen zone 2 can move to the ultra-low-oxygen zone 3.

[0076] The low-oxygen zone 1 and the ultra-low-oxygen zone 3 are added on the basis of the normal-oxygen zone 2. The pretreatment stage is carried out in the low-oxygen zone 1, which can make some complex or refractory organic matter degraded, provide a large amount of easily degradable small molecular organic matter, and preserve some aerobic microorganisms, thus laying a foundation for the aerobic fermentation, making the temperature rise faster, and making the fermentation effect of the refractory or complex organic matter better. The temperature reduction and composting stages are carried out in the ultra-low-oxygen zone 3, and most of the organic matter is decomposed in the later stage of composting, so that high aeration is not needed. When the micro-aeration is carried out, not only the aerobic microorganisms, but also the facultative microorganisms and the anaerobic microorganisms can survive, so that the refractory or complex organic matter can be degraded again. The ultra-low-oxygen zone 3 can achieve a better humification level.

[0077] The oxygen concentration sensors include the low-oxygen zone oxygen concentration sensor 17, the normal-oxygen zone oxygen concentration sensor 4, and the ultra-low-oxygen zone oxygen concentration sensor 8. The low-oxygen zone oxygen concentration sensor 17 is used to detect the oxygen concentration in the material in the low-oxygen zone 1, the normal-oxygen zone oxygen concentration sensor 4 is used to detect the oxygen concentration in the material in the normal-oxygen zone 2, and the ultra-low-oxygen zone oxygen concentration sensor 8 is used to detect the oxygen concentration in the material in the ultra-low-oxygen zone 3.

[0078] The aeration device can aerate the material in the low-oxygen zone 1, the normal-oxygen zone 2, and the ultra-low-oxygen zone 3 respectively, so as to provide appropriate oxygen for the low-oxygen zone 1, the normal-oxygen zone 2, and the ultra-low-oxygen zone 3 respectively.

[0079] The normal-oxygen zone temperature sensor 5 is used to detect the temperature of the material in the normal-oxygen zone 2, and the normal-oxygen zone moisture sensor 23 is used to detect the moisture content of the material in the normal-oxygen zone 2.

[0080] The aeration device, the low-oxygen zone oxygen concentration sensor 17, the normal-oxygen zone oxygen concentration sensor 4, the ultra-low-oxygen zone oxygen concentration sensor 8, the normal-oxygen zone temperature sensor 5, and the normal-oxygen zone moisture sensor 23 are electrically connected with the control device 6. The control device 6 can control the aeration of the aeration device in each zone according to the oxygen concentration in the material in each zone.

[0081] The temperature and the moisture content of the material in the normal-oxygen zone 2 can indirectly reflect the degradation process of the organic matter in the normal-oxygen zone 2. When the material in the normal-oxygen zone 2 is aerated, the current time set value of the oxygen concentration in the material in the normal-oxygen zone 2 is determined according to the current time temperature of the material in the normal-oxygen zone 2 and the current time moisture content of the material in the normal-oxygen zone 2, and the aeration device is controlled according to the current time set value of the oxygen concentration and the current time oxygen concentration of the material in the normal-oxygen zone 2.

[0082] In this way, the real-time demand of the aerobic zone 2 for the oxygen concentration is determined according to the real-time condition of the aerobic zone 2, the real-time demand of the aerobic zone 2 for the oxygen concentration is set as the set value of the oxygen concentration of the aerobic zone 2 in real time, and then the aeration amount of the aeration device is controlled according to the real-time detection value of the aerobic zone oxygen concentration sensor 4 and the set value of the oxygen concentration of the aerobic zone 2 set in real time, so that the consistency of the set value of the oxygen concentration of the aerobic zone 2 and the real-time actual demand of the aerobic zone 2 for the oxygen concentration is improved, the fermentation effect of the aerobic zone 2 can be effectively ensured, and the problems of the material fermentation effect of the composting reactor being not ideal, the humification degree being low, the nutrient loss being large, and the energy consumption being high in the related art are solved.

[0083] In the embodiment of the present application, the relationship among the current time temperature of the material in the aerobic zone 2, the current time moisture content of the material in the aerobic zone 2, and the current time set value of the oxygen concentration in the material in the aerobic zone 2 is C1=a*WC-b*T1+e. Wherein, C1 is the current time set value of the oxygen concentration in the material in the aerobic zone 2, the unit of C1 is percentage (symbol %), WC is the current time moisture content of the material in the aerobic zone 2, the unit of WC is percentage (symbol %), T1 is the current time temperature of the material in the aerobic zone 2, the unit of T1 is Celsius (symbol ℃). a, b and e are all constants, which can be determined through multiple tests. In some embodiments, according to the test, a=3.366, b=0.198, and e=22.336.

[0084] The current time temperature T1 of the material in the aerobic zone 2 is detected by the aerobic zone temperature sensor 5, the current time moisture content of the material in the aerobic zone 2 is detected by the aerobic zone moisture sensor 23, and the current time set value C1 of the oxygen concentration in the material in the aerobic zone 2 is calculated and determined according to the above relationship C1=a*WC-b*T1+e. At the same time, the oxygen concentration in the material in the aerobic zone 2 is detected in real time by the aerobic zone oxygen concentration sensor 4, and the aeration amount of the aeration device at the current time is controlled according to the detected oxygen concentration in the material in the aerobic zone 2 and the current time set value C1 of the oxygen concentration in the material in the aerobic zone 2 calculated and determined.

[0085] Specifically, when the aeration device is controlled according to the current time set value of the oxygen concentration and the current time oxygen concentration of the material in the aerobic zone 2, the current time setting range of the oxygen concentration can be determined according to the current time set value of the oxygen concentration. Then the aeration device is controlled according to the current time setting range of the oxygen concentration.

[0086] The oxygen concentration set value corresponding to each time is a numerical range, which is more convenient for control.

[0087] In a specific embodiment, the lower limit of the current time setting range can be set to 95% of the current time setting value of the oxygen concentration, and the upper limit of the current time setting range can be set to 105% of the current time setting value of the oxygen concentration.

[0088] When the detected oxygen concentration in the material in the normoxic zone 2 is lower than 95% of the current time setting value of the calculated oxygen concentration in the material in the normoxic zone 2, the aeration device is controlled to increase the aeration amount. When the detected oxygen concentration in the material in the normoxic zone 2 is higher than 105% of the current time setting value of the calculated oxygen concentration in the material in the normoxic zone 2, the aeration device is controlled to decrease the aeration amount or stop aeration. When the detected oxygen concentration in the material in the normoxic zone 2 is higher than 95% of the current time setting value of the calculated oxygen concentration in the material in the normoxic zone 2 and lower than 105% of the current time setting value of the calculated oxygen concentration in the material in the normoxic zone 2, the aeration amount of the aeration device is not changed.

[0089] In the embodiment of the present application, when the aeration amount of the low-oxygen zone 1 and the super-low-oxygen zone 3 is controlled, the oxygen concentration setting range needs to be set for the low-oxygen zone 1 and the super-low-oxygen zone 3 respectively.

[0090] The low-oxygen zone oxygen concentration sensor 17 detects the oxygen concentration in the material in the low-oxygen zone 1 in real time, and the control device controls the aeration device according to the detected oxygen concentration in the material in the low-oxygen zone 1 and the oxygen concentration setting range corresponding to the low-oxygen zone 1. When the detected oxygen concentration in the material in the low-oxygen zone 1 is lower than the lower limit of the oxygen concentration setting range of the low-oxygen zone 1, the aeration device is controlled to increase the aeration amount. When the detected oxygen concentration in the material in the low-oxygen zone 1 is higher than the upper limit of the oxygen concentration setting range of the low-oxygen zone 1, the aeration device is controlled to decrease the aeration amount or stop aeration. When the detected oxygen concentration in the material in the low-oxygen zone 1 is higher than the lower limit of the oxygen concentration setting range of the low-oxygen zone 1 and lower than the upper limit of the oxygen concentration setting range of the low-oxygen zone 1, the aeration amount of the aeration device is not changed.

[0091] Similarly, the oxygen concentration sensor 8 detects the oxygen concentration in the material in the ultra-low oxygen zone 3 in real time, and the control device controls the aeration device according to the detected oxygen concentration in the material in the ultra-low oxygen zone 3 and the oxygen concentration setting range corresponding to the ultra-low oxygen zone 3. When the detected oxygen concentration in the material in the ultra-low oxygen zone 3 is lower than the lower limit of the oxygen concentration setting range of the ultra-low oxygen zone 3, the control device increases the aeration amount. When the detected oxygen concentration in the material in the ultra-low oxygen zone 3 is higher than the upper limit of the oxygen concentration setting range of the ultra-low oxygen zone 3, the control device reduces the aeration amount or stops the aeration. When the detected oxygen concentration in the material in the ultra-low oxygen zone 3 is higher than the lower limit of the oxygen concentration setting range of the ultra-low oxygen zone 3 and lower than the upper limit of the oxygen concentration setting range of the ultra-low oxygen zone 3, the aeration amount of the control device is unchanged.

[0092] In specific embodiments, the oxygen concentration setting range of the material in the low oxygen zone 1 can be 3% to 5%. The oxygen concentration setting range of the material in the ultra-low oxygen zone 3 can be 1% to 3%.

[0093] In the embodiments of the present application, the aeration device includes an aerator 10, an aeration pipeline, and a first connecting pipeline 11.

[0094] The aerator 10 is arranged outside the reactor body. The aeration pipeline is arranged inside the reactor body and located at the bottom of the reactor body. The side wall of the aeration pipeline is provided with aeration holes arranged at intervals. The first connecting pipeline 11 is arranged outside the reactor body, and the first connecting pipeline 11 connects the aeration pipeline and the aerator 10.

[0095] When the aerator 10 is running, it can transport air or oxygen and other gases into the aeration pipeline and transport them into the reactor body through the aeration holes, thereby supplementing oxygen for the normal oxygen zone 2. Arranging the aeration pipeline at the bottom of the reactor body can promote the uniform distribution of oxygen in the material in the normal oxygen zone 2 and significantly improve the ventilation efficiency of the normal oxygen zone 2.

[0096] In the embodiments, the reactor body includes a box body 12, a partition plate assembly, and a separation assembly.

[0097] The inside of the box body 12 has a containing space, the partition plate assembly is arranged at the bottom of the box body 12, and the partition plate assembly has a spacing with the bottom wall of the box body 12 to form an aeration cavity.

[0098] The partition plate assembly is provided with a plurality of communication holes arranged at intervals, and the communication holes can only allow the gas in the aeration cavity to flow upward to the partition plate assembly, and the moisture above the partition plate assembly cannot flow into the aeration cavity. Specifically, the diameter of the communication hole can be controlled to be in the range of 2 to 10 mm.

[0099] To avoid accidental leakage of moisture above the partition plate assembly to the aeration chamber, a cleaning hole with controllable opening and closing state can be provided at the position of the side wall of the tank 12 corresponding to the aeration chamber, so as to periodically clean the aeration chamber. Each aeration chamber corresponds to a cleaning hole.

[0100] The partition assembly is arranged in the aeration chamber, and the partition assembly divides the aeration chamber into a micro-aeration chamber 14, an aerobic aeration chamber 15 and a low-oxygen aeration chamber 16. The micro-aeration chamber 14 is located below the low-oxygen zone 1, the aerobic aeration chamber 15 is located below the normal-oxygen zone 2, and the low-oxygen aeration chamber 16 is located below the super-low-oxygen zone 3.

[0101] Specifically, the partition plate assembly includes a low-oxygen zone partition plate 7, a normal-oxygen zone partition plate 9 and a super-low-oxygen zone partition plate 13.

[0103] In specific embodiments, the diameter of the communication hole on the low-oxygen zone partition plate 7 is set to 2-5 mm, and the opening rate of the low-oxygen zone partition plate 7 is controlled within the range of 10%-20%. The diameter of the communication hole on the normal-oxygen zone partition plate 9 is set to 5-10 mm, and the opening rate of the normal-oxygen zone partition plate 9 is controlled within the range of 20%-50%. The diameter of the communication hole on the super-low-oxygen zone partition plate 13 is set to 2-5 mm, and the opening rate of the super-low-oxygen zone partition plate 13 is controlled within the range of 10%-20%.

[0104] The aeration pipeline includes a first aeration pipeline 18, a second aeration pipeline 19 and a third aeration pipeline 20. The first aeration pipeline 18 is arranged in the micro-aeration chamber 14, the second aeration pipeline 19 is arranged in the aerobic aeration chamber 15, and the third aeration pipeline 20 is arranged in the low-oxygen aeration chamber 16. In this way, after the gas enters the corresponding aeration chamber, it can be uniformly distributed in the aeration chamber, and then flow to the reaction zone through the communication hole, increasing the aeration area range of the aeration device in each reaction zone, and the aeration is more uniform. Moreover, direct contact between the aeration pipeline and the material can be avoided, which is beneficial to prolong the service life of the aeration pipeline.

[0105] The first connecting pipeline 11 has three branch pipelines, which are connected with the first aeration pipeline 18, the second aeration pipeline 19 and the third aeration pipeline 20 respectively. The first control valve 21 and the flow meter 22 are arranged on the three branch pipelines, the first control valve 21 can control the on-off state of the branch pipeline and adjust the flow in the branch pipeline.

[0106] The flow meter 22 and the first control valve 21 are electrically connected with the control device 6.

[0107] The partition assembly includes a partition strip 39, the low-oxygen zone 1, the normal-oxygen zone 2 and the ultra-low-oxygen zone 3 are distributed along the longitudinal direction of the reactor body, the partition strip 39 extends along the transverse direction of the reactor body, and the partition strip 39 is sealingly connected to the bottom wall of the box body 12, the side wall of the box body 12 and the partition plate assembly, so that the micro-aerobic aeration cavity 14, the aerobic aeration cavity 15 and the low-oxygen aeration cavity 16 are independent of each other to avoid mutual influence.

[0108] Supporting blocks 40 are further arranged between the partition plate assembly and the bottom wall of the box body 12 to support the partition plate assembly and improve the rigidity of the partition plate assembly. The supporting blocks 40 are arranged in a plurality of intervals.

[0109] The partition plate assembly can be detachably connected with the box body 12, the partition strip 39 and the supporting blocks 40 for later maintenance.

[0110] In the embodiment of the application, the reactor body is internally provided with a stirring device, and a lifting mechanism is arranged between the low-oxygen zone oxygen concentration sensor 17 and the top wall of the reactor body, between the normal-oxygen zone oxygen concentration sensor 4 and the top wall of the reactor body, between the ultra-low-oxygen zone oxygen concentration sensor 8 and the top wall of the reactor body, between the normal-oxygen zone temperature sensor 5 and the top wall of the reactor body, and between the normal-oxygen zone moisture sensor 23 and the top wall of the reactor body. The lifting mechanism can drive any one of the low-oxygen zone oxygen concentration sensor 17, the normal-oxygen zone oxygen concentration sensor 4, the ultra-low-oxygen zone oxygen concentration sensor 8, the normal-oxygen zone temperature sensor 5 and the normal-oxygen zone moisture sensor 23 to lift to adjust the height of any one of the low-oxygen zone oxygen concentration sensor 17, the normal-oxygen zone oxygen concentration sensor 4, the ultra-low-oxygen zone oxygen concentration sensor 8, the normal-oxygen zone temperature sensor 5 and the normal-oxygen zone moisture sensor 23.

[0111] The stirring device and the lifting mechanism are electrically connected with the control device 6. When the stirring device is running, the control device 6 can control the low-oxygen-zone oxygen concentration sensor 17, the normal-oxygen-zone oxygen concentration sensor 4, the ultra-low-oxygen-zone oxygen concentration sensor 8, the normal-oxygen-zone temperature sensor 5 and the normal-oxygen-zone moisture sensor 23 to rise to the top of the reactor body. When the stirring device is stopped, the control device 6 can control the low-oxygen-zone oxygen concentration sensor 17, the normal-oxygen-zone oxygen concentration sensor 4, the ultra-low-oxygen-zone oxygen concentration sensor 8, the normal-oxygen-zone temperature sensor 5 and the normal-oxygen-zone moisture sensor 23 to descend to be immersed in the material.

[0112] In the embodiment, the stirring device comprises a support seat 24, a first driving mechanism, a mounting seat 25, a second driving mechanism, a spiral stirring mechanism 26 and a scraper 28.

[0113] The support seat 24 is movable along the longitudinal direction of the reactor body relative to the reactor body, and the first driving mechanism is used to drive the support seat 24 to move along the longitudinal direction of the reactor body.

[0114] The mounting seat 25 is arranged on the support seat 24, and the support seat 24 can drive the mounting seat 25 to move along the longitudinal direction of the reactor body.

[0115] The mounting seat 25 is movable along the transverse direction of the reactor body relative to the support seat 24. The second driving mechanism is used to drive the mounting seat 25 to move along the transverse direction of the reactor body.

[0116] The spiral stirring mechanism 26 is arranged on the mounting seat 25, and the mounting seat 25 can drive the spiral stirring mechanism 26 to move along the longitudinal direction of the reactor body and also can drive the spiral stirring mechanism 26 to move along the transverse direction of the reactor body.

[0117] The spiral stirring shaft 27 of the spiral stirring mechanism 26 is rotatable about its own axis relative to the mounting seat 25. Through the rotation of the spiral stirring shaft 27, the material can be stirred. The spiral stirring shaft 27 is arranged obliquely relative to the bottom wall of the reactor body. By controlling the rotation direction of the spiral stirring shaft 27, the material can be moved in the direction from the low-oxygen zone 1 to the ultra-low-oxygen zone 3, so as to realize continuous composting.

[0118] The spiral stirring mechanism 26 has the functions of stirring and longitudinal conveying at the same time, and does not need to additionally arrange a longitudinal conveying device for the material, which is favorable for simplifying the structure of the reactor, reducing the floor area and reducing energy consumption.

[0119] The scraper 28 is located below the spiral stirring shaft 27. The scraper 28 is fixed relative to the mounting seat 25. When the mounting seat 25 moves along the longitudinal direction of the reactor body, the scraper 28 is used to scrape the material on the bottom wall of the low-oxygen zone 1, the bottom wall of the normal-oxygen-zone 2 and the bottom wall of the ultra-low-oxygen-zone 3, so as to reduce the accumulation of the material on the bottom of the reactor body and improve the conveying efficiency.

[0120] The scraper 28 interacts with the partition plate assembly, the aeration pipeline is arranged below the partition plate assembly, interference of the aeration pipeline on the scraper 28 can be avoided, wear of the aeration pipeline can be avoided, durability is improved, and service life is prolonged.

[0121] Specifically, the spiral stirring shaft 27 can be arranged as a hollow shaft, and the scraper 28 has a connecting shaft which is arranged in the hollow shaft and is fixedly connected with the mounting seat 25.

The end wall of the end where the discharge port of the box body 12 is located is close to the spiral stirring shaft 27, and the material in the ultra-low oxygen zone 3 can be transported to the discharge port through the rotation of the spiral stirring shaft 27, so that the material is discharged from the discharge port.

[0124] The inclination angle of the spiral stirring shaft 27 can be controlled within the range of 10°~20°, and specifically, the inclination angle of the spiral stirring shaft 27 can be set to 15°.

[0125] It should be noted that the discharge port is provided with a sealing plate, and in a natural state, the sealing plate closes the discharge port. When the spiral stirring shaft 27 transports the material to the discharge port, the material exerts a pressing force on the sealing plate, so that the sealing plate can be rotated to open the discharge port.

[0126] In the embodiment, the stirring device further comprises a stirring oxygen concentration sensor, which is arranged on the spiral stirring mechanism 26. The stirring oxygen concentration sensor is used to detect the oxygen concentration in the material around the spiral stirring mechanism 26 in real time when the stirring device is running, so as to determine the region where the spiral stirring mechanism 26 is located according to the detected oxygen concentration in the material around the spiral stirring mechanism 26, and then control the rotating speed of the spiral stirring mechanism 26.

[0127] For different regions in the low-oxygen zone 1, the normal-oxygen zone 2 and the ultra-low-oxygen zone 3, the rotating speed of the spiral stirring mechanism is different. When the spiral stirring mechanism 26 is in the low-oxygen zone 1, the spiral stirring mechanism 26 is controlled to rotate 10~20 times per minute; when the spiral stirring mechanism 26 is in the normal-oxygen zone 2, the spiral stirring mechanism 26 is controlled to rotate 20~30 times per minute; and when the spiral stirring mechanism 26 is in the ultra-low-oxygen zone 3, the spiral stirring mechanism 26 is controlled to rotate 5~10 times per minute.

[0128] The self-propelled precise cooperative control intelligent composting reactor provided by the embodiment of the present application enables the spiral stirring mechanism 26 to run once from the direction of the charging port to the discharging port of the reactor body, and can push the material in the reactor body to move in the direction from the low-oxygen zone to the ultra-low-oxygen zone. Specifically, the spiral stirring mechanism 26 can be operated once a day.

[0129] In the embodiment, first support guide mechanisms are respectively arranged between the two ends of the transverse direction of the support seat 24 and the reactor body, and the first support guide mechanism comprises a first guide groove 29 and a first roller 30.

[0133] The bottom wall of the first guide groove 29 supports the first roller 30, which can bear the load, avoiding the influence of gravity and the like on the first gear 32 and the first rack 31. The meshing transmission of the first gear 32 and the first rack 31 is not affected by the gravity of the support seat 24, the mounting seat 25, the spiral stirring mechanism 26 and the like, which reduces the load of the first rack 31 and the first driving member 37, is beneficial to the miniaturization of the first driving member 37, reduces the mass of the first driving member 37, further reduces the load of the support seat 24, reduces the energy consumption, and reduces the deformation of the support seat 24 and the first rack 31.

The load of the second rack 35 and the second driving member 38 is reduced, which is conducive to the miniaturization of the second driving member 38, reduces the mass of the second driving member 38, further reduces the load of the mounting base 25, reduces the energy consumption, and reduces the deformation of the mounting base 25 and the second rack 35.

After the feeding device 41 is disconnected with the connecting bracket 43, the feeding device 41 can move reciprocally between the reactor body and the material source to transport materials. When the feeding device 41 transports materials to the reactor body, the feeding device 41 is connected with the connecting bracket 43, and the third driving mechanism is controlled to operate, so as to drive the feeding device 41 to ascend along the guide bracket 42 to gradually approach the charging port of the reactor body.

[0145] One end of the feeding device 41 is open, and the open end of the feeding device 41 is arranged upward when the connecting bracket 43 is located on the vertical bracket. Correspondingly, when the connecting bracket 43 is located on the second end of the arc-shaped bracket, the plane where the open end of the feeding device 41 is located is perpendicular to the longitudinal direction of the reactor body. At this time, the materials in the feeding device 41 can be unloaded by themselves.

[0149] To ensure the stability and reliability of the third driving mechanism and prevent the chain 45 from being disconnected from the chain wheel 44, a counterweight can be arranged at the second end of the chain 45 to ensure the reliable engagement between the chain 45 and the chain wheel 44.
