Description

Technical Field

[0001] This utility model relates to the field of enzyme production technology, specifically to an enzyme production device for soil remediation. Background Technology

[0002] Soil remediation refers to the process of treating and improving contaminated or degraded soil through physical, chemical, or biological technologies to restore its ecological function, fertility, or safety. Enzymes in soil remediation are biocatalysts that catalyze the decomposition or transformation of organic matter. These enzymes are typically secreted by microorganisms (such as bacteria and fungi) or synthesized artificially. They can accelerate the degradation process of pollutants, particularly effective against organic pollutants such as petroleum hydrocarbons, pesticides, and heavy metal chelates. To continuously and stably produce highly efficient enzymes for soil remediation, enzyme production equipment is usually used. Enzyme production equipment is a system for the large-scale production of soil remediation enzymes, typically including fermentation tanks, mixing systems, temperature control systems, oxygen supply systems, and post-processing equipment. The fermentation tank provides an anaerobic or aerobic fermentation environment to promote microbial growth and metabolism. The use of production equipment accelerates the decomposition process of pollutants, shortens the remediation cycle, and reduces remediation costs.

[0003] When producing enzymes using an enzyme production device, a stirring component is usually installed inside the device to stir the enzymes in order to promote sufficient contact between air and enzymes and to ensure the uniform distribution of nutrients. However, existing stirring components usually use a motor-driven stirring shaft to rotate the stirring rod, which often results in relatively simple stirring. Consequently, the stirring range and area are limited, making it difficult to expand the stirring range and area to achieve mixing of enzymes in different areas. This can easily lead to uneven and insufficient mixing, which is not conducive to improving production quality and effect. Therefore, in order to solve the above problems, an enzyme production device for soil remediation is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an enzyme production device for soil remediation, in order to solve the problem mentioned in the background art that the stirring is often relatively simple, and thus the range and area of ​​stirring are relatively limited, which is not conducive to expanding the stirring range and area and realizing the mixing of enzymes in different areas. This easily leads to uneven and insufficient mixing, which is not conducive to improving production quality and effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an enzyme production device for soil remediation, comprising a fermentation tank, an inlet fixedly connected to the inner side of the fermentation tank, a discharge port fixedly connected to the bottom end of the fermentation tank, an air inlet pipe fixedly connected to the surface of the fermentation tank, an exhaust pipe fixedly connected to the inner side of the fermentation tank, a stirring shaft movably connected to the inner side of the fermentation tank, a stirring rod fixedly connected to the surface of the stirring shaft, a first motor provided at the top end of the stirring shaft, and the output end of the stirring shaft and the first motor fixedly connected;

[0006] The connecting plate is fixedly connected to the inner wall of the fermenter. A reciprocating screw is movably connected to the inner side of the connecting plate. The reciprocating screw is movably connected to the fermenter. A connecting block is movably connected to the surface of the reciprocating screw. A fixing frame is fixedly connected to the surface of the connecting block. The first motor is fixedly installed inside the fixing frame. The feed inlet and exhaust pipe both pass through the connecting plate.

[0007] Preferably, the reciprocating mechanism further includes a fixed block, which is fixedly connected to the top of the fermenter. A rotating rod is movably connected to the inner side of the fixed block. A first conical tooth is fixedly connected to the surface of the rotating rod. A second motor is fixedly installed on the surface of the fixed block. A second conical tooth is fixedly connected to the top of the reciprocating screw.

[0008] Preferably, the reciprocating lead screw is movably connected to the fermenter in two sets, and the connecting blocks are movably connected to the reciprocating lead screw in two sets.

[0009] Preferably, the first conical teeth are in two sets and fixedly connected to the rotating rod, the rotating rod is fixedly connected to the output end of the second motor, and the stirring shaft is movable inside the connecting plate and the fixed frame.

[0010] Preferably, a discharge mechanism is provided inside the discharge port. The discharge mechanism includes a spiral conveying rod, which is movably connected to the inside of the discharge port. A third motor is fixedly installed at the bottom of the discharge port. A fixing plate is fixedly connected to the surface of the spiral conveying rod, and a scraper is fixedly connected to the surface of the fixing plate.

[0011] Preferably, the spiral conveyor rod is fixedly connected to the output end of the third motor, the fixing plate is fixedly connected to the spiral conveyor rod in two groups, and the scraper is correspondingly connected to the fixing plate in two groups.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The rotation of the rotating rod by the second motor enables the transmission of the first conical tooth to the second conical tooth and the reciprocating screw. In turn, the connecting block can drive the fixed frame to reciprocate vertically under the action of the reciprocating screw. This allows the stirring shaft to move vertically along with the stirring rod as it rotates, facilitating the stirring of enzymes at different positions on the stirring rod. This expands the stirring range, promotes the uniformity of enzyme mixing and the fullness of fermentation, better ensures the production quality of enzymes, and facilitates better soil remediation.

[0014] 2. The screw conveyor is driven by a third motor to rotate, which can transport the enzyme in the discharge port. This facilitates the stable discharge of the enzyme through the discharge port and ensures the stability and continuity of the output. At the same time, the fixed plate and scraper are set up so that when the fixed plate and scraper rotate under the action of the screw conveyor, the scraper can rub against the inner wall of the fermentation tank, thereby scraping the bottom wall of the fermentation tank and preventing enzyme accumulation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] The first motor 17, the second motor 24, and the third motor 31 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] An enzyme production device for soil remediation includes a fermentation tank 1. An inlet 11 is fixedly connected to the inner side of the fermentation tank 1, a discharge port 12 is fixedly connected to the bottom of the fermentation tank 1, an air inlet pipe 13 is fixedly connected to the surface of the fermentation tank 1, an exhaust pipe 14 is fixedly connected to the inner side of the fermentation tank 1, a stirring shaft 15 is movably connected to the inner side of the fermentation tank 1, a stirring rod 16 is fixedly connected to the surface of the stirring shaft 15, a first motor 17 is installed at the top of the stirring shaft 15, and the output ends of the stirring shaft 15 and the first motor 17 are fixedly connected. Enzymes can be added through the inlet 11, sterile gas can be discharged through the air inlet 13, and exhaust gas can be discharged through the exhaust pipe 14. The operation of the first motor 17, in conjunction with the operation of the stirring shaft 15, drives the stirring rod 16 to rotate, enabling the stirring rod 16 to stir the enzymes, thereby facilitating enzyme fermentation and production.

[0024] A reciprocating mechanism is provided inside the fermentation tank 1. The reciprocating mechanism includes a connecting plate 2, which is fixedly connected to the inner wall of the fermentation tank 1. A reciprocating screw 25 is movably connected to the inner side of the connecting plate 2. The reciprocating screw 25 is movably connected to the fermentation tank 1. A connecting block 27 is movably connected to the surface of the reciprocating screw 25. A fixing frame 28 is fixedly connected to the surface of the connecting block 27. A first motor 17 is fixedly installed inside the fixing frame 28. The feed inlet 11 and the exhaust pipe 14 both pass through the connecting plate 2. Through the setting of the connecting block 27, when the reciprocating screw 25 rotates, the connecting block 27 can drive the fixing frame 28 to perform vertical reciprocating motion. As a result, the stirring shaft 15 and the stirring rod 16 can rise and fall accordingly during rotation, which facilitates the expansion of the stirring range and the mixing of enzymes in different positions. This results in more uniform enzyme quality, which is beneficial to improving the quality and effect of fermentation and making it easier to use for soil remediation.

[0025] Furthermore, the reciprocating mechanism also includes a fixed block 21, which is fixedly connected to the top of the fermentation tank 1. A rotating rod 22 is movably connected to the inner side of the fixed block 21. A first conical tooth 23 is fixedly connected to the surface of the rotating rod 22. A second motor 24 is fixedly installed on the surface of the fixed block 21. A second conical tooth 26 is fixedly connected to the top of the reciprocating screw 25. By rotating the rotating rod 22 to drive the first conical tooth 23 to rotate, the first conical tooth 23 can transmit power to the second conical tooth 26, which facilitates the rotation of the reciprocating screw 25 to enable the connecting block 27 to drive the fixed frame 28 to move vertically.

[0026] Furthermore, the reciprocating screw 25 is movably connected to the fermentation tank 1 in two sets, and the connecting blocks 27 are connected to the reciprocating screw 25 in two sets. Through the setting of the reciprocating screw 25, the connecting blocks 27 can move vertically under the action of the reciprocating screw 25, thereby enabling the fixed frame 28 to drive the first motor 17 and the stirring shaft 15 to change their positions, so that the stirring rod 16 can stir at different positions and heights.

[0027] Furthermore, the first conical teeth 23 are fixedly connected to the rotating rod 22 in two sets. The rotating rod 22 is fixedly connected to the output end of the second motor 24. The stirring shaft 15 is movable inside the connecting plate 2 and the fixed frame 28. Through the setting of the first conical teeth 23, the first conical teeth 23 rotate when the rotating rod 22 rotates. In this way, the first conical teeth 23 can transmit power to the second conical teeth 26, which facilitates the rotation of the reciprocating screw 25.

[0028] Furthermore, a discharge mechanism is provided inside the discharge port 12. The discharge mechanism includes a screw conveyor 3, which is movably connected to the inside of the discharge port 12. A third motor 31 is fixedly installed at the bottom of the discharge port 12. A fixing plate 32 is fixedly connected to the surface of the screw conveyor 3, and a scraper 33 is fixedly connected to the surface of the fixing plate 32. With the setting of the fixing plate 32, the fixing plate 32 can drive the scraper 33 to rotate during the rotation of the screw conveyor 3. As a result, the scraper 33 rotates and rubs against the inner wall of the fermentation tank 1, which can scrape the bottom wall of the fermentation tank 1 and prevent the accumulation of enzymes.

[0029] Furthermore, the screw conveyor 3 and the output end of the third motor 31 are fixedly connected. The fixed plate 32 is fixedly connected to the screw conveyor 3 in two groups. The scraper 33 is connected to the fixed plate 32 in two groups. The screw conveyor 3 is driven to rotate by the third motor 31, so that the screw conveyor 3 can convey the enzyme in the discharge port 12, which facilitates the stable discharge of the enzyme and can prevent the discharge blockage.

[0030] Working principle: In use, the second motor 24 is electrically connected to an external power source. The operator starts the second motor 24 by pressing the switch. The second motor 24 drives the rotating rod 22 to rotate. The first conical tooth 23 will rotate under the action of the rotating rod 22 and transmit power to the second conical tooth 26, thereby realizing the rotation of the reciprocating screw 25. The rotation of the reciprocating screw 25 allows the connecting block 27 to move on the surface of the reciprocating screw 25 and drive the fixed frame 28 to perform vertical reciprocating motion. Thus, when the stirring shaft 15 drives the stirring rod 16 to rotate, the stirring shaft 15 and the stirring rod 16 can reciprocate under the action of the fixed frame 28, so that the stirring rod 16 can stir the enzyme in different areas and positions.

[0031] The third motor 31 is electrically connected to an external power source. The operator starts the third motor 31 by pressing a switch. The operation of the third motor 31 drives the spiral conveyor rod 3 to rotate. The rotation of the spiral conveyor rod 3 can transport the enzyme, so that the enzyme can be stably discharged through the discharge port 12, thus avoiding the enzyme from clogging in the discharge port 12. The setting of the fixing plate 32 can drive the scraper 33 to rotate under the action of the spiral conveyor rod 3. The rotation of the scraper 33 and the friction between the scraper 33 and the bottom wall of the fermentation tank 1 can scrape the wall of the fermentation tank 1, thereby preventing the enzyme from accumulating.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
