Description

Technical Field

[0001] This application relates to the field of suspension processing technology, and in particular to a mother liquor mixing and stirring device for preparing Bacillus hygroscopicus suspension. Background Technology

[0002] Highland Bacillus suspension, as a novel microbial preparation, is formed through multiple processes including crushing, feeding, mixing, primary and secondary sand milling, quality inspection, and filling of water, Bacillus (crushed), lignin, ethylene glycol, and Kathon. In recent years, it has shown great application potential in agriculture, environmental protection, and other fields. It uses Highland Bacillus as the active ingredient and utilizes modern biotechnology to stably suspend it in a specific medium, achieving efficient microbial function and convenient application.

[0003] The existing mixing and stirring equipment used for processing Bacillus hygroscopicus suspensions is not thorough enough in actual mixing. During mixing, some materials will stick to the inner wall of the mixing tank and cannot fully participate in the mixing, which will affect the purity and efficiency of the mother liquor formation. Therefore, this application proposes a mother liquor mixing and stirring equipment for the preparation of Bacillus hygroscopicus suspensions. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a mother liquor mixing and stirring device for preparing Bacillus hygroscopicus suspension, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a mother liquor mixing and stirring device for preparing Bacillus cereus suspension, comprising a tank, a sealing cover installed on the top of the tank, a discharge pipe connected to the bottom of the tank, a filter assembly for separating materials inside the tank installed on the outside of the discharge pipe, a rotating shaft rotatably installed on the inner wall of the sealing cover, a drive unit for driving the rotating shaft to rotate installed on the top of the sealing cover, a spiral blade installed on the outer edge of the rotating shaft, multiple nozzles fixedly connected to the outer edge of the rotating shaft, a crossbar fixedly connected to the outer edge of the rotating shaft, a U-shaped scraper installed at the bottom of the crossbar, a push plate installed on the inner side of the U-shaped scraper, and multiple pressure relief grooves evenly distributed on the inner wall of the push plate.

[0006] By adopting the above technical solution, when the pusher plate pushes the material using the pressure relief groove, some of the material flows through the pressure relief groove, which avoids the material at the edge from forming high-pressure agglomeration due to pushing. At the same time, it enhances the radial flow of the material and improves the mixing efficiency.

[0007] In a preferred embodiment, the bottom of the sealing cap is provided with multiple pins, and the top of the tank is provided with multiple mating holes corresponding to the multiple pins, and the multiple pins are adapted to be inserted into the inner wall of the multiple mating holes.

[0008] By adopting the above technical solution, the sealing cap can be stably installed on the top of the tank by using the pin and the mating hole, thus ensuring that the sealing cap will not easily fall off the top of the tank, and further facilitating the removal of the sealing cap from the top of the tank.

[0009] In a preferred embodiment, the filter assembly includes a filter bag fitted over the outside of the discharge pipe at the end furthest from the tank. The filter bag is secured with a clamp, and a control valve is rotatably installed inside the discharge pipe.

[0010] By adopting the above technical solution, when the material mixed inside the tank is discharged to the outside through the discharge pipe, the material can be separated into solid and liquid by using a filter bag, which ensures the purity of the extracted mother liquor. In addition, the filter bag can be locked to the outer edge of the discharge pipe by using clamps, thereby ensuring that the impact force of the material when it is discharged into the discharge pipe will not cause the filter bag to detach from the discharge pipe.

[0011] In a preferred embodiment, the drive unit includes a motor mounted on the top of the sealing cover. The output shaft of the motor is fixedly connected to a drive gear, the teeth of which mesh with a driven gear, and the driven gear is fixed to the outside of the rotating shaft.

[0012] By adopting the above technical solution, the drive motor can drive the active gear to rotate, and then drive the driven gear to rotate the rotating shaft and the spiral blades to mix and stir the materials inside the tank.

[0013] In a preferred embodiment, the outer wall of the U-shaped scraper is fitted to the inner wall of the tank, the bottom of the U-shaped scraper and the bottom of the tank are both arc-shaped, and the bottom end of the rotating shaft is fixedly connected to the U-shaped scraper.

[0014] By adopting the above technical solution, the U-shaped scraper can be used to rotate against the inner wall of the tank, thereby scraping off the material adhering to the inner wall of the tank and allowing it to fully participate in the mixing. Furthermore, the arc-shaped design reduces residue during material feeding, further ensuring the thoroughness of material feeding.

[0015] In a preferred embodiment, a water inlet is installed on the top of the rotating shaft, and the nozzle, rotating shaft and water inlet are connected.

[0016] By adopting the above technical solution, a water pipe can be inserted into the water inlet, and the pump force can be used to fill the inside of the rotating shaft with water. Then, the nozzle can be used to flush the inner wall of the tank. Furthermore, the inside of the tank can be cleaned after the mixing operation is completed. At the same time, the drive unit can be used to rotate the rotating shaft to achieve all-round cleaning and ensure thoroughness.

[0017] In a preferred embodiment, the top of the sealing cover is fixedly connected to the outer ring of the bearing, and the outer edge of the rotating shaft is fixed to the inner ring of the bearing.

[0018] By adopting the above technical solution, the shaft can be limited during rotation, thereby ensuring the stability of the shaft during rotation and preventing it from easily shifting or swaying in position.

[0019] In a preferred embodiment, the top of the sealing cover is provided with a feed inlet, and the inner wall of the feed inlet is threaded with a cover plate.

[0020] By adopting the above technical solution, water, Bacillus (after crushing), lignin, ethylene glycol and Kathon raw materials can be put into the inside of the tank for stirring and mixing. At the same time, after the material is discharged, the cover plate can be installed inside the feed inlet to seal the opening of the feed inlet.

[0021] The beneficial effects of this application are: This is a mother liquor mixing and stirring device for preparing Bacillus subtilis suspension. It uses a drive unit to rotate a shaft and a spiral blade to mix and stir the materials inside the tank. The rotation of the spiral blade can move the materials inside the tank up and down to ensure thorough mixing. Furthermore, a pusher plate can push the materials at the edge to the center of the tank, and the rotation of the U-shaped scraper can scrape off the materials adhering to the inner wall of the tank, allowing them to fully participate in the stirring and ensuring the purity and efficiency of the mother liquor formation.

[0022] This is a mother liquor mixing and stirring device for preparing Bacillus subtilis suspension. After opening the control valve, the material inside the tank can be discharged into the collection container through the discharge pipe. Further solid-liquid separation of the material can be carried out using a filter bag to ensure that the extracted mother liquor does not contain impurities. At the same time, the filter bag can be disassembled by removing the clamp, thereby realizing the collection of impurities. Attached Figure Description

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Reference Figure 1-5 A mixing and stirring device for preparing Bacillus cereus suspension includes a tank 1, a sealing cover 2 installed on the top of the tank 1, a discharge pipe 4 connected to the bottom of the tank 1, a filter assembly for separating the material inside the tank 1 installed on the outside of the discharge pipe 4, a rotating shaft 8 rotatably installed on the inner wall of the sealing cover 2, a drive unit for driving the rotating shaft 8 to rotate installed on the top of the sealing cover 2, a spiral blade 9 installed on the outer edge of the rotating shaft 8, multiple nozzles 10 fixedly connected to the outer edge of the rotating shaft 8, a crossbar 11 fixedly connected to the outer edge of the rotating shaft 8, a U-shaped scraper 12 installed at the bottom of the crossbar 11, a pusher plate 13 installed on the inner side of the U-shaped scraper 12, and multiple pressure relief grooves 14 evenly distributed on the inner wall of the pusher plate 13. This allows some material to flow through the pressure relief grooves 14 when the pusher plate 13 pushes the material, preventing the edge material from forming high-pressure agglomeration due to pushing, while enhancing the radial flow of the material and improving the mixing efficiency.

[0027] See Figure 3 The bottom of the sealing cap 2 is equipped with multiple pins 3, and the top of the tank body 1 is provided with multiple mating holes corresponding to the multiple pins 3. The multiple pins 3 are adapted to be inserted into the inner wall of the multiple mating holes, so that the sealing cap 2 can be stably installed on the top of the tank body 1 by using the pins 3 in conjunction with the mating holes, thereby ensuring that the sealing cap 2 will not easily fall off the top of the tank body 1, and further facilitating the removal of the sealing cap 2 from the top of the tank body 1.

[0028] See Figure 1 , Figure 2 and Figure 4The filter assembly includes a filter bag 6, which is fitted onto the outside of the discharge pipe 4 at the end away from the tank 1. The filter bag 6 is locked with a clamp 7. A control valve 5 is rotatably installed inside the discharge pipe 4, so that when the material mixed inside the tank 1 is discharged to the outside through the discharge pipe 4, the filter bag 6 can be used to perform solid-liquid separation of the material, ensuring the purity of the extracted mother liquor. The clamp 7 can also lock the filter bag 6 to the outer edge of the discharge pipe 4, thereby ensuring that the impact force of the material when it is discharged into the discharge pipe 4 will not cause the filter bag 6 to detach from the discharge pipe 4.

[0029] See Figure 1 - Figure 3 and Figure 5 The drive unit includes a motor 15, which is mounted on the top of the sealing cover 2. The output shaft of the motor 15 is fixedly connected to a drive gear 16, and the teeth of the drive gear 16 mesh with a driven gear 17. The driven gear 17 is fixed to the outside of the rotating shaft 8, so that the motor 15 can drive the drive gear 16 to rotate, and then drive the rotating shaft 8 and the spiral blades 9 to rotate through the driven gear 17 to mix and stir the material inside the tank 1.

[0030] See Figure 4 and Figure 5 The outer wall of the U-shaped scraper 12 is in contact with the inner wall of the tank 1. The bottom of the U-shaped scraper 12 and the bottom of the tank 1 are both arc-shaped. The bottom end of the rotating shaft 8 is fixedly connected to the U-shaped scraper 12, so that the U-shaped scraper 12 can rotate in contact with the inner wall of the tank 1, thereby scraping off the material adhering to the inner wall of the tank 1, so that it can fully participate in the mixing. The arc-shaped design can reduce residue during feeding, further ensuring the thoroughness of feeding.

[0031] See Figure 2 and Figure 3 The top of the rotating shaft 8 is equipped with a water inlet hole. The nozzle 10, the rotating shaft 8 and the water inlet hole are connected, so that a water pipe can be inserted into the water inlet hole. Then, the pump force can be used to fill the inside of the rotating shaft 8 with water. Then, the nozzle 10 can be used to flush the inner wall of the tank 1. Furthermore, the inside of the tank 1 can be cleaned after the mixing operation is completed. At the same time, it can be used with the drive unit to drive the rotating shaft 8 to rotate to achieve all-round cleaning and ensure thoroughness.

[0032] See Figure 5 The outer ring of the bearing 18 is fixedly connected to the top of the sealing cover 2, and the outer edge of the rotating shaft 8 is fixed to the inner ring of the bearing 18, so that the rotating shaft 8 can be used to limit the rotation during rotation, thereby ensuring the stability of the rotating shaft 8 during rotation and ensuring that it will not easily shift or swing in position.

[0033] See Figure 3The top of the sealing cover 2 is equipped with a feed inlet 19, and the inner wall of the feed inlet 19 is threaded with a cover plate 20, so that water, Bacillus (after crushing), lignin, ethylene glycol and Kathon raw materials can be put into the inside of the tank 1 for stirring and mixing. At the same time, the cover plate 20 can be installed inside the feed inlet 19 after the feeding is finished to seal the opening of the feed inlet 19.

[0034] Working principle: First, water, pulverized Bacillus, lignin, ethylene glycol and Kathon raw materials can be added into the tank 1 through the feed inlet 19 for mixing. At the same time, after the feeding is finished, the cover plate 20 can be installed into the feed inlet 19 to seal the opening of the feed inlet 19. Then the drive motor 15 drives the drive gear 16 to rotate, which in turn drives the driven gear 17 to rotate the shaft 8 and the spiral blade 9 to mix and stir the material inside the tank 1. The rotation of the spiral blade 9 can move the material inside the tank 1 up and down to ensure thorough mixing. Furthermore, the push plate 13 can push the material at the edge to the middle of the tank 1, and the rotation of the U-shaped scraper 12 can scrape off the material adhering to the inner wall of the tank 1, so that it can fully participate in the stirring until the mother liquor is formed. When the control valve 5 is opened, the material inside the tank 1 can be discharged into the collection container through the discharge pipe 4. The material can then be further separated into solid and liquid by the filter bag 6 to ensure that the extracted mother liquor does not contain impurities. At the same time, removing the clamp 7 can disassemble the filter bag 6, thereby enabling the collection of impurities. Finally, the water pipe can be inserted into the water inlet, and the pump force can be used to fill the inside of the rotating shaft 8 with water. Then, the nozzle 10 can be used to flush the inner wall of the tank 1. Furthermore, the inside of the tank 1 can be cleaned after the mixing operation is completed. At the same time, the drive unit can be used to drive the rotating shaft 8 to rotate to achieve all-round cleaning and ensure thoroughness.
