Description

Technical Field

[0001] This invention relates to the technical field of mixing devices, specifically to a raw material mixing device for the production of functional soil remediation agents. Background Technology

[0002] With the rapid development of modern agriculture, the amount of organic waste generated during agricultural production is increasing, such as fruit and vegetable residues. If these wastes are not handled properly, they will not only pollute the environment but also waste valuable agricultural resources. Therefore, how to efficiently and environmentally treat these agricultural organic wastes has become an important issue facing the sustainable development of agriculture. Soil remediation agents provide an effective solution to this problem. Soil remediation agents are substances that can improve soil structure, increase soil fertility, and promote plant growth. Using agricultural organic waste to prepare soil remediation agents can not only realize the resource utilization of waste but also reduce environmental pollution and promote the sustainable development of agriculture.

[0003] However, the mixing and processing of raw materials is a crucial step in the preparation of soil remediation agents. Traditional mixing methods often involve directly mixing agricultural organic waste and its heat treatment products with composting bacteria. This method has several problems. First, large pieces of agricultural organic waste and dry heat treatment products are not easy to mix evenly, affecting the quality of the soil remediation agent. Second, when directly mixed, the composting bacteria are difficult to penetrate into the organic waste due to the high moisture content, and most of them are lost with the liquid, resulting in a reduced utilization rate of the bacteria and an increased input cost. In addition, directly mixed soil remediation agents have high moisture content, making them difficult to store and transport, which limits their application scope. Summary of the Invention

[0004] The purpose of this invention is to provide a raw material mixing device for the production of functional soil remediation agents, so as to solve the problem mentioned in the background that traditional mixing devices are difficult to thoroughly and evenly mix agricultural organic waste additives and thermal treatment products when preparing soil remediation agents.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a raw material mixing device for the production of functional soil remediation agents, comprising a premixing tank, wherein a microbial culture tank is wrapped around the premixing tank, the microbial culture tank is used to cultivate composting microbial strains, and an electromechanical sealed chamber is provided at one end of the premixing tank, wherein a geared motor is provided inside the electromechanical sealed chamber; The premixing tank is equipped with a premixing coil, one end of which is fixedly connected to an extrusion coil. An extrusion filter cylinder is located outside the extrusion coil, and a rotating sleeve is located outside the extrusion filter cylinder. A stirring tank is located at one end of the rotating sleeve, and a stirring rod is located inside the stirring tank. The stirring rod is fixedly connected to one end of the extrusion coil. A conveying pump is located on the right side of the stirring tank. The inlet of the conveying pump is connected to the inoculum culture tank through a conveying pipe, and the outlet of the conveying pump is connected to an inoculum spraying pipe located inside the stirring tank. A material outlet is opened on the outer wall of the stirring tank, and a discharge pipe is located below the material outlet. A discharge baffle is located at the upper end of the discharge pipe.

[0006] In one example, the premixed pulley system comprises four pulleys: a first pulley, a second pulley, a third pulley, and a fourth pulley. One end of the first pulley is fixedly connected to a first drive pulley, which is also fixedly connected to the drive shaft of a reduction motor. One end of the second pulley is fixedly connected to a first driven pulley, which is connected to the first drive pulley via a synchronous belt. A first drive gear is also fixedly connected to one end of the second pulley. One end of the third pulley is fixedly connected to a first driven gear, which meshes with the first driven gear. A second drive pulley is also fixedly connected to one end of the third pulley. A second driven pulley is fixedly connected to one end of the fourth pulley, which is connected to the second drive pulley via a synchronous belt.

[0007] In one example, the first, second, third, and fourth coils are interlaced, and the edges of the first, second, third, and fourth coils are processed with shearing serrations.

[0008] In one example, the first and second spirals have the same spiral direction, the third and fourth spirals have the same spiral direction, the first and fourth spirals have opposite spiral directions, and the second and third spirals have opposite spiral directions. Because of the gear and pulley transmission, the first and second spirals rotate in the same direction, and the third and fourth spirals rotate in the same direction. When their spiral directions are the same, interference and collision are less likely to occur when they rotate in the same direction. When the first and fourth spirals rotate in opposite directions, and the second and third spirals rotate in opposite directions, interference and collision are less likely to occur when they rotate in opposite directions.

[0009] In one example, the electromechanical sealed chamber is embedded inside the microbial culture tank, and the outer wall of the electromechanical sealed chamber is provided with heat exchange plates. The heat exchange plates are used to enhance the heat exchange between the electromechanical sealed chamber and the microbial culture tank. When the premixing auger in the premixing tank mixes, stirs and crushes the materials, it generates heat due to friction. At the same time, the geared motor also generates a lot of heat when it is working. The heat exchange plates can quickly transfer the heat in the electromechanical sealed chamber to the microbial culture tank, so that the microorganisms in the microbial culture tank can be temperature controlled by the heat generated by the operation of the equipment. This allows the microorganisms to be cultivated and propagated in a low-temperature environment with lower heating costs. At the same time, the culture medium in the microbial culture tank can also dissipate heat and cool down the electromechanical equipment.

[0010] In one example, the extrusion filter cylinder is provided in four sets, and a fixed connecting plate is fixedly connected to one end of each of the four sets of extrusion filter cylinders. The fixed connecting plate is rotatably connected to the rotating sleeve.

[0011] In one example, a tapered extrusion tube is fixedly connected to one end of the extrusion coil. The minimum diameter of the tapered extrusion tube is the same as the diameter of the main shaft of the extrusion coil, and the maximum diameter of the tapered extrusion tube is smaller than the diameter of the extrusion filter cylinder. As the extrusion coil pushes the material, the diameter of the tapered extrusion tube gradually increases, causing the gap between the tapered extrusion tube and the inner wall of the extrusion filter cylinder to gradually decrease, thereby squeezing the material, squeezing out the water in the material, and allowing it to flow into the rotating sleeve through the extrusion filter cylinder.

[0012] In one example, an end sealing plate is fixedly connected to one end of the conical extrusion tube. An extrusion forming groove is formed around the end sealing plate. A cross shearing blade is fixedly connected to the fixed connection plate. The cutting edge of the cross shearing blade is flush with the outlet of the extrusion forming groove. Thus, when the material is extruded from the extrusion forming groove, rotating the end sealing plate will cause the material to be cut into granules by the cross shearing blade.

[0013] In one example, a nutrient solution collection tank is provided on one side of the rotating sleeve, and a spiral tube is connected to one side of the nutrient solution collection tank. A rotating sealing plate is fixedly connected to one end of the spiral tube, and the rotating sealing plate is rotatably connected to the inoculum culture tank. A nutrient solution injection port is opened on the upper part of one side of the inoculum culture tank. When the spiral tube rotates to the top, it communicates with the nutrient solution injection port. Thus, when the rotating sleeve rotates, the water and juice squeezed out of the material will be collected in the nutrient solution collection tank and then flow into the bottom spiral tube. As the spiral tube rotates and rises to the nutrient solution injection port, the water and juice squeezed out of the material will flow into the inoculum culture tank through the nutrient solution injection port.

[0014] In one example, an internal gear ring is fixedly connected to the inner side of one end of the rotating sleeve, and a second driving gear is fixedly connected to one end of the stirring rod. The second driving gear meshes with a second driven gear, and the second driven gear is rotatably connected to the rotating sleeve. The second driven gear meshes with the internal gear ring, so that when the extrusion coil drives the stirring rod to rotate, the stirring rod will drive the second driving gear to rotate, the second driving gear will drive the second driven gear to rotate, and then the second driven gear will drive the rotating sleeve to rotate through meshing with the internal gear ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention proposes a raw material mixing device for the production of functional soil remediation agents. By setting up a microbial culture tank outside the premixing tank, the juice containing a large amount of organic matter discharged from the mixing, crushing and extrusion of agricultural waste is used as a nutrient solution and collected in the microbial culture tank. The heat generated by the motor and moving mechanism during equipment operation is used to create suitable temperature conditions for microbial cultivation. At the same time, the culture solution in the microbial culture tank can also dissipate heat and cool the equipment. The two complement each other, which not only saves costs for temperature control of the microbial culture tank, but also improves the heat dissipation capacity of the equipment, and also promotes the propagation of microorganisms, greatly reducing the input cost of microorganisms.

[0016] 2. The present invention proposes a raw material mixing device for the production of functional soil remediation agents. By using a premixing torsion mixer to initially crush and mix agricultural waste and thermal treatment products, the crushed mixture is then extruded, dehydrated, and molded to process the waste into low-moisture particles. The granular materials can be easily and evenly mixed during stirring, which is more efficient and effective than directly mixing different wastes. Furthermore, when spraying bacterial inoculants, the low-moisture particles can absorb the liquid bacterial inoculants into their interiors, resulting in higher bacterial inoculant utilization and easier transportation.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-8 As shown, a raw material mixing device for the production of functional soil remediation agents includes a premixing tank 1, which is wrapped with a microbial culture tank 10 for cultivating composting microbial strains. An electromechanical sealed chamber 11 is provided at one end of the premixing tank 1, and a geared motor 9 is provided inside the electromechanical sealed chamber 11. The electromechanical sealed chamber 11 is embedded inside the microbial culture tank 10, and a heat exchange plate 1101 is provided on the outer wall of the electromechanical sealed chamber 11 for enhancing the heat exchange between the electromechanical sealed chamber 11 and the microbial culture tank 10. When the premixing coil 2 in the premixing tank 1 mixes, stirs and crushes the materials, it generates heat due to friction. At the same time, the geared motor 9 also generates a lot of heat. The heat exchange plate 1101 can quickly transfer the heat in the electromechanical sealed chamber 11 to the microbial culture tank 10, so that the microbial culture in the microbial culture tank 10 can be temperature controlled by the heat generated by the equipment. This allows the microbial culture to be cultivated and propagated in a low-temperature environment with lower heating costs. At the same time, the culture medium in the microbial culture tank 10 can also dissipate heat and cool down the electromechanical equipment.

[0021] The premixing tank 1 is equipped with four premixing rollers 2: a first roller 201, a second roller 202, a third roller 203, and a fourth roller 204. One end of the first roller 201 is fixedly connected to a first driving pulley 3, which is also fixedly connected to the drive shaft of a reduction motor 9. One end of the second roller 202 is fixedly connected to a first driven pulley 4, and the first driving pulley 3 and the first driven pulley 4 are connected by a synchronous belt. One end of the second roller 202 is also fixedly connected to a first driving gear 5, and one end of the third roller 203 is fixedly connected to a first driven gear 6. The first driving gear 5 and the first driven gear 6 mesh with each other. The third coil 203 is fixedly connected to a second driving pulley 7 at one end, and the fourth coil 204 is fixedly connected to a second driven pulley 8 at one end. The second driving pulley 7 and the second driven pulley 8 are connected by a synchronous belt drive, so that the reduction motor 9 can drive the first coil 201 to rotate. The first coil 201 drives the second coil 202 to rotate through the cooperation of the first driving pulley 3 and the first driven pulley 4. The second coil 202 can drive the third coil 203 to rotate through the mutual meshing of the first driving gear 5 and the first driven gear 6. The third coil 203 can also drive the fourth coil 204 to rotate through the cooperation of the second driving pulley 7 and the second driven pulley 8.

[0022] In one embodiment, the first coil 201, the second coil 202, the third coil 203, and the fourth coil 204 are interleaved. The edges of the first coil 201, the second coil 202, the third coil 203, and the fourth coil 204 are processed with shearing serrations 205. This not only mixes and stirs the material, but also cuts and crushes the material using the interleaved shearing serrations 205 on the edges of the first coil 201, the second coil 202, the third coil 203, and the fourth coil 204. This has a good crushing effect on agricultural waste and makes it easier for the material to be mixed more evenly.

[0023] In one embodiment, the first spiral 201 and the second spiral 202 have the same spiral direction, the third spiral 203 and the fourth spiral 204 have the same spiral direction, the first spiral 201 and the fourth spiral 204 have opposite spiral directions, and the second spiral 202 and the third spiral 203 have opposite spiral directions. Because the first spiral 201 and the second spiral 202 rotate in the same direction and the third spiral 203 and the fourth spiral 204 rotate in the same direction under the transmission of gears and pulleys, interference and collision are less likely to occur when they rotate in the same direction when their spiral directions are the same. The first spiral 201 and the fourth spiral 204 rotate in opposite directions and the second spiral 202 and the third spiral 203 rotate in opposite directions, so interference and collision are less likely to occur when they rotate in opposite directions when their spiral directions are opposite.

[0024] One end of the premixed spiral 2 is fixedly connected to an extrusion spiral 14. An extrusion filter cylinder 12 is provided on the outside of the extrusion spiral 14. A rotating sleeve 19 is provided on the outside of the extrusion filter cylinder 12. There are four sets of extrusion filter cylinders 12, and one end of each set of extrusion filter cylinders 12 is fixedly connected to a fixed connecting plate 13. The fixed connecting plate 13 is rotatably connected to the rotating sleeve 19. One end of the extrusion spiral 14 is fixedly connected to a conical extrusion tube 15. The minimum diameter of the conical extrusion tube 15 is the same as the diameter of the main shaft of the extrusion spiral 14, and the maximum diameter of the conical extrusion tube 15 is smaller than the diameter of the extrusion filter cylinder 12. In this way, when the extrusion spiral 14 pushes the material, the diameter of the conical extrusion tube 15 gradually increases, which causes the gap between the conical extrusion tube 15 and the inner wall of the extrusion filter cylinder 12 to gradually decrease, thereby squeezing the material, squeezing out the water in the material and flowing through the extrusion filter cylinder 12 into the rotating sleeve 19. A nutrient solution collection tank 1901 is provided on one side of the rotating sleeve 19. A spiral tube 1902 is connected to one side of the nutrient solution collection tank 1901. A rotating sealing plate 1903 is fixedly connected to one end of the spiral tube 1902. The rotating sealing plate 1903 is rotatably connected to the inoculum culture tank 10. A nutrient solution inlet 1001 is opened on the upper part of one side of the inoculum culture tank 10. When the spiral tube 1902 rotates to the top, it connects with the nutrient solution inlet 1001. Thus, when the rotating sleeve 19 rotates, the water and juice squeezed out of the material will be collected in the nutrient solution collection tank 1901 and then flow into the spiral tube 1902 at the bottom. When the spiral tube 1902 rotates and rises to the nutrient solution inlet 1001, the water and juice squeezed out of the material will flow into the inoculum culture tank 10 through the nutrient solution inlet 1001. The juice squeezed out of the organic species of agricultural waste also contains a large amount of organic matter, which is an excellent source of nutrients for the propagation of composting bacteria.

[0025] An internal gear ring 20 is fixedly connected to the inner side of one end of the rotating sleeve 19, and a second driving gear 21 is fixedly connected to one end of the stirring rod 18. The second driving gear 21 meshes with a second driven gear 22. The second driven gear 22 is rotatably connected to the rotating sleeve 19, and the second driven gear 22 meshes with the internal gear ring 20. Thus, when the extrusion coil 14 drives the stirring rod 18 to rotate, the stirring rod 18 will drive the second driving gear 21 to rotate, and the second driving gear 21 will drive the second driven gear 22 to rotate. In turn, the second driven gear 22 drives the rotating sleeve 19 to rotate through meshing with the internal gear ring 20.

[0026] In one embodiment, an end sealing plate 16 is fixedly connected to one end of the tapered extrusion tube 15. An extrusion forming groove 1601 is formed around the end sealing plate 16. A cross shearing blade 17 is fixedly connected to the fixed connecting plate 13. The cutting edge of the cross shearing blade 17 is flush with the outlet of the extrusion forming groove 1601. Thus, when the material is extruded from the extrusion forming groove 1601, rotating the end sealing plate 16 will cause the material to be cut into granules by the cross shearing blade 17.

[0027] A stirring tank is provided at one end of the rotating sleeve 19. A stirring rod 18 is provided inside the stirring tank. The stirring rod 18 is fixedly connected to one end of the extrusion coil 14. A conveying pump 23 is provided on the right side of the stirring tank. The inlet of the conveying pump 23 is connected to the inoculum culture tank 10 through the conveying pipe 24. The outlet of the conveying pump 23 is connected to the inoculum spraying pipe 25. The inoculum spraying pipe 25 is located inside the stirring tank. A material outlet 26 is opened on the outer wall of the stirring tank. A discharge pipe 27 is provided below the material outlet 26. A discharge baffle 2701 is provided at the upper end of the discharge pipe 27.

[0028] Working principle: During mixing, agricultural waste and heat treatment products are first poured into the premixing tank 1. Then, the reduction motor 9 is started, driving the first coiler 201 to rotate. The first coiler 201 drives the second coiler 202 to rotate through the engagement of the first driving pulley 3 and the first driven pulley 4. The second coiler 202 drives the third coiler 203 to rotate through the meshing of the first driving gear 5 and the first driven gear 6. The third coiler 203 can also drive the third coiler 203 to rotate through the engagement of the second driving pulley 7 and the second driven pulley 8. The cooperation of the four premixing coils 204 and 205 drives the fourth coil to rotate, thus making all four premixing coils 2 rotate. The shearing saw teeth 205 perform preliminary cutting, crushing and premixing of the mixture. Then, the premixing coil 2 drives the extrusion coil 14 to rotate. When the extrusion coil 14 pushes the material, the diameter of the conical extrusion tube 15 gradually increases, which causes the gap between the conical extrusion tube 15 and the inner wall of the extrusion filter cylinder 12 to gradually decrease, thereby extruding the material and squeezing out the water in the material and flowing into the rotating sleeve 19 through the extrusion filter cylinder 12.

[0029] The extrusion coil 14 can drive the stirring rod 18 to rotate, which in turn drives the second drive gear 21 to rotate. The second drive gear 21 drives the second driven gear 22 to rotate, and the second driven gear 22 drives the rotating sleeve 19 to rotate through meshing with the internal gear ring 20. When the rotating sleeve 19 rotates, the water and juice squeezed out of the material will be concentrated in the nutrient solution collection tank 1901 and then flow into the bottom spiral tube 1902. As the spiral tube 1902 rotates and rises to the nutrient solution inlet 1001, the water and juice squeezed out of the material will flow into the inoculum culture tank 10 through the nutrient solution inlet 1001 as a nutrient source for the propagation of composting bacteria. The inoculum culture tank 10 uses the heat generated by the operation of the electromechanical equipment as a heat source to control the culture temperature at low cost.

[0030] The dehydrated material is extruded into strips through the extrusion molding tank 1601. At the same time, the rotation of the end sealing plate 16 causes the material to be cut into granules by the cross shear blade 17 and fall into the mixing tank. Under the action of the stirring rod 18, the material is stirred evenly. Meanwhile, the delivery pump 23 draws liquid bacteria from the inoculum culture tank 10 and sprays it evenly into the stirred granular material through the inoculum spray pipe 25. Then, the granular material with low water content absorbs the liquid bacteria into its interior.
