Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer production equipment, in particular to an organic fertilizer raw material mixing and stirring device. Background Art

[0003] The importance of organic fertilizer is increasing day by day. Organic fertilizer is a product that contains both the nutrients needed by crops and microorganisms. It is a combination of biological, organic and inorganic. It can replace chemical fertilizers and provide various nutrients required for the growth and development of crops. Through the use of organic fertilizers, we can gradually achieve the goal of using less or no chemical fertilizers in farmland and use organic fertilizers as a substitute, thereby reducing damage to the environment.

[0004] Bio-organic fertilizer has a high organic matter content, which can improve the soil, improve the physical and chemical properties of the soil, enhance the soil's ability to retain water, fertilizer and fertilizer, and alleviate the soil compaction caused by the long-term use of chemical fertilizers; organic fertilizer raw materials include a variety of organic substances, such as livestock and poultry manure, crop straw, urban garbage, mushroom residue, etc. Each raw material has its own unique characteristics and advantages and disadvantages. Selecting the best combination of raw materials can produce high-quality organic fertilizer. The current conventional organic fertilizer production process mainly includes ingredients, crushing, mixing, granulation, rounding, drying and other steps. The raw materials are crushed and put into a mixing tank, and are cut into finer powders by a cutting knife while stirring, and finally form granular powder materials so that they can be put into a granulator for granulation.

[0005] However, there are still some problems in the current mixing and stirring step when it is implemented. On the one hand, in the conventional mixing tank, the cutting blade and the stirrer are an integrated structure, driven by a rotating shaft, and the cutting and stirring are performed by rotation. However, the organic fertilizer raw material contains more organic matter, has a larger viscosity, and is easily accumulated at the bottom of the mixing tank. The cutting blade is difficult to play an effective breaking up and mixing operation, resulting in insufficient cutting fineness of the part of the material that sinks to the bottom, affecting the subsequent granulation effect. In addition, because its process is generally carried out using a mixing tank, after the mixing and stirring is completed, it is necessary to transport it to a granulator through equipment such as a conveyor belt. After the organic fertilizer raw material is crushed, cut and stirred, a large amount of dust will be emitted, which will drift to the inside of the production workshop during transportation, causing serious dust pollution. At the same time, because this dust contains a large amount of fine organic powder, when using traditional dust removal equipment to reduce dust, it is also easy to cause adhesion and hardening, and frequent cleaning and maintenance are required, which brings great inconvenience to production work. The present invention aims to provide a new mixing and stirring device to reduce the dust pollution degree after the mixing and stirring of organic fertilizer raw materials, thereby avoiding the problem of dust pollution. Summary of the invention

[0011] Furthermore, a feeding funnel is correspondingly arranged above the feeding port.

[0012] Furthermore, the rotating frame is a cylindrical frame structure, and concave rotating bearings are arranged at the upper and lower ends of the inner wall of the tank body corresponding to the two ends of the rotating frame. The rotating frame is rotatably connected to the inside of the tank body through the rotating bearings, so that the rotating frame can only rotate axially relative to the tank body and will not move vertically.

[0013] Furthermore, a hollow gear cavity is provided at the top of the tank body, and the gear cavity is located above the rotating frame. A driving gear is arranged around the outside of the area where the rotating shaft is located in the gear cavity, and a first driven gear is meshed with the outside of the driving gear. A connecting shaft is provided at the bottom of the first driven gear, and the connecting shaft passes through the gear cavity and extends into the stirring cavity inside the tank body. A second driven gear is coaxially provided at the bottom of the connecting shaft, and an annular internal gear is arranged around the inner side of the top edge of the rotating frame, and the annular internal gear is meshed with the second driven gear.

[0014] Furthermore, the spiral blades are inclined downward from the side close to the rotating frame to the side close to the center of the tank body on each horizontal plane, forming an overall inward-inclined spiral structure.

[0015] Furthermore, the dust control component includes a detection mechanism and a humidifying mechanism, wherein the detection mechanism is used to detect the dust concentration inside the tank body, and the humidifying mechanism is electrically connected to the detection mechanism. When the dust concentration detected by the detection mechanism is greater than a set threshold, the humidifying mechanism is controlled to spray water toward the inside of the tank body, thereby increasing the humidity of the organic fertilizer raw material and correspondingly reducing the dust concentration.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The tank body of the present invention has both an internal cutting mechanism and an external stirring mechanism, wherein the internal cutting mechanism drives the cutting blade to rotate through the rotating shaft, thereby cutting the material in the tank body and crushing it into finer particles, while the external stirring mechanism drives the spiral blade by the rotating frame of the cylindrical structure, so that the spiral blade rotates around the cutting blade, and the tank body material is continuously transported upward. Because the material at the bottom of the tank body is affected by the centrifugal force driven by the cutting blade to rotate, it will continuously move toward the edge of the tank body, so it will always contact with the spiral blade and be transported from the bottom of the tank body to the top of the tank body, and then fall from the middle of the tank body and be crushed by the cutting blade again. In this way, the material inside the tank body forms an up and down reciprocating cycle, which can not only fully contact with the cutting blade, but also achieve more sufficient mixing during the up and down movement process, forming a raw material with a more uniform texture, thereby improving the quality of subsequent granulation;

[0022] 2. The present invention further provides a dust control assembly on the tank body, including a detection mechanism and a humidifying mechanism, wherein the detection mechanism is used to detect the dust concentration inside the tank body, and the humidifying mechanism is electrically connected to the detection mechanism. When the dust concentration detected by the detection mechanism is greater than a set threshold value, the humidifying mechanism is controlled to spray water toward the inside of the tank body, thereby increasing the humidity of the organic fertilizer raw material and correspondingly reducing the dust concentration. In this way, the dust concentration inside the tank body can be maintained at a normal level, and there will be no situation in which too much dust is spread into the factory building after discharging to cause serious pollution, and there will be no problem of too much viscosity affecting the discharging due to the excessive humidity of the raw material.

[0029] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1 As shown, an embodiment of the present invention proposes an organic fertilizer raw material mixing and stirring device, including a tank body 1 and a stirring assembly arranged inside the tank body 1. In this embodiment, the tank body 1 is a vertically arranged closed cylindrical structure, and a stirring chamber is formed inside. A feed port is provided at the top of the tank body 1, a feed funnel 11 is correspondingly provided above the feed port, and a discharge port with a hatch 13 is provided at the bottom. Preferably, four supporting legs 12 are also provided at the bottom of the tank body 1, and the supporting legs 12 support the tank body 1 off the ground, so that a conveyor belt can be correspondingly provided below the discharge port at the bottom of the tank body 1, so as to facilitate the transportation of the stirred raw materials to the granulation equipment.

[0031] like Figure 2 As shown, in this embodiment, the stirring assembly includes an inner cutting mechanism and an outer stirring mechanism. The inner cutting mechanism includes a rotating shaft 3 coaxially arranged inside the tank body 1 and a cutting blade 2 fixedly arranged on the rotating shaft 3. One end of the rotating shaft 3 extends outside the top of the tank body 1 and is connected to a motor 31. The diameter of the cutting blade 2 is smaller than the inner diameter of the tank body 1. When the motor 31 rotates, it drives the rotating shaft 3 to drive the cutting blade 2 to rotate, thereby cutting the internal material into finer particles.

[0032] Correspondingly, the external stirring mechanism includes a cylindrical rotating frame 5 arranged close to the inner wall of the tank body 1, the rotating frame 5 is rotatably installed inside the tank body 1, and a spiral blade 4 is arranged on the inner side of the rotating frame 5, and the spiral blade 4 is arranged spirally from top to bottom along the inner side of the rotating frame 5, and the width of the spiral blade 4 is smaller than the distance between the outer end of the cutting blade 2 and the rotating frame 5, so that the spiral blade 4 and the cutting blade 2 will not interfere with each other during rotation. In order to reduce the gap for material to fall, the gap between the adjacent sides of the spiral blade 4 and the cutting blade 2 is reduced as much as possible, so that the material can be cut during the falling process.

[0033] In the specific scheme of this embodiment, the rotating frame 5 is a cylindrical frame structure, and concave rotating bearings are provided at the upper and lower ends of the inner wall of the tank body 1 corresponding to the positions of the two ends of the rotating frame 5. The rotating frame 5 is rotatably connected to the inside of the tank body 1 through the rotating bearing, so that the rotating frame 5 can only rotate axially relative to the tank body 1 and will not move vertically.

[0034] like Figure 3As shown, as the driving structure of the rotating frame 5, a hollow gear cavity is also provided at the top of the tank body 1, and the gear cavity is located above the rotating frame 5. A driving gear 32 is arranged around the outside of the area of ​​the rotating shaft 3 located in the gear cavity. A first driven gear 33 is arranged on the outside of the driving gear 32 in meshing engagement. A connecting shaft 34 is arranged at the bottom of the first driven gear 33, and the connecting shaft 34 passes through the gear cavity and extends into the stirring cavity inside the tank body 1. A second driven gear 35 is coaxially arranged at the bottom of the connecting shaft 34. An annular internal gear is arranged around the inner side of the top edge of the rotating frame 5, and the annular internal gear is meshed with the second driven gear 35. When the motor 31 drives the rotating shaft 3 to rotate, it also drives the driving gear 32 to rotate, and then drives the first driven gear 33, the connecting shaft 34 and the second driven gear 35 to rotate together. Then the second driven gear 35 drives the annular internal gear, that is, drives the rotation of the rotating frame 5, and realizes the rotation and lifting of the spiral blade 4. In the preferred solution, the first driven gear 33, the connecting shaft 34 and the second driven gear 35 are symmetrically arranged in multiple groups, thereby increasing the contact points with the annular internal gear and making the drive more stable. The setting of the gear cavity can isolate the driving gear 32 and the first driven gear 33 from the stirring cavity of the tank body 1, reducing the influence of dust on the gear drive.

[0035] In this embodiment, the spiral blade 4 is preferably inclined downward from the side close to the rotating frame 5 to the side close to the center of the tank body 1 on each horizontal plane, forming an overall inward-inclined spiral structure. In this way, the material will continuously tilt and slide toward the middle of the tank body 1 during the lifting process, avoiding the material being completely moved to the top of the tank body 1, resulting in excessive local density. In this way, all positions of the cutting blade 2 can effectively contact the material, and the cutting efficiency is higher.

[0036] In the embodiment of the present invention, a dust control component is further provided on the top of the tank body 1, and the dust control component adds water into the tank body 1 according to the dust concentration inside the tank body 1, thereby achieving the effect of dust reduction. The dust control component includes a detection mechanism 6 and a humidification mechanism, wherein the detection mechanism 6 is used to detect the dust concentration inside the tank body 1, and the humidification mechanism is electrically connected to the detection mechanism 6. When the dust concentration detected by the detection mechanism 6 is greater than the set threshold value, the humidification mechanism is controlled to spray water toward the inside of the tank body 1, thereby increasing the humidity of the organic fertilizer raw material and correspondingly reducing the dust concentration.

[0037] like Figure 4As shown, in a further solution, the detection mechanism 6 includes a detection box 61, which is a closed double-layer box structure, including a detection layer 611 and a cleaning layer 612 arranged from bottom to top. The detection box 61 is fixed on the top surface of the tank body 1. A telescopic rod 62 is arranged on the top of the detection box 61. The fixed section of the telescopic rod 62 is fixedly arranged outside the top of the detection box 61, and the movable section penetrates and extends into the detection box 61. A detection block 63 made of a transparent material is fixedly arranged at the end of the movable section of the telescopic rod 62. Openings are arranged between the cleaning layer 612 and the detection layer 611, and between the detection layer 611 and the inside of the tank body 1, so that the detection block 63 can just pass through the openings and enter the inside of the tank body 1, the detection layer 611 and the cleaning layer 612 respectively. After the detection block 63 stays in the tank body 1 for a predetermined time, dust will be attached to the surface, and then the telescopic rod 62 will shrink, and the detection block 63 will be retracted into the detection layer 611 to detect the amount of dust attached to its surface, and then the dust concentration inside the tank body 1 is determined. If the dust concentration is high, the humidification mechanism sprays water into the tank body 1 to reduce dust; if the dust concentration is normal, no water is sprayed. Then the telescopic rod 62 is retracted again, and the detection block 63 is moved to the cleaning layer. After the surface of the detection block 63 is cleaned, it is extended into the tank body 1 again, and the above work is repeated.

[0038] Specifically, the detection layer 611 has a laser emitter 64 and a laser receiver 65 arranged opposite to each other, and the light path direction emitted by the laser emitter 64 passes through the moving track of the detection block 63. According to the attenuation of the intensity of the light received by the laser receiver 65, the amount of dust attached to the surface of the detection block 63 can be determined, and then the dust concentration in the tank body 1 can be determined.

[0039] A number of spray heads 66 are arranged in the cleaning layer 612, and the spray heads 66 are arranged around the position of the detection block 63 in the cleaning layer 612. A hot air blower 67 and a drain pipe 68 are also arranged on both sides of the cleaning layer 612. The air outlet of the hot air blower 67 is arranged toward the moving track of the detection block 63. When the detection block 63 moves to the cleaning layer 612, the spray head 66 sprays water toward its surface to wash away the dust, and then the hot air blower 67 is started to blow a hot air flow toward the surface of the detection block 63, which can not only dry the surface of the detection block 63 to prevent dust from sticking, but also discharge the sewage through the drain pipe 68 to avoid affecting the cleanliness of the inside of the cleaning layer 612.

[0040] Furthermore, the humidification mechanism includes a water storage tank 7 arranged on the top of the tank body 1, and a water spray head is provided at the bottom of the water storage tank 7, and the water spray head extends into the inside of the tank body 1 toward the material below.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
