Description

Technical Field

[0001] This utility model relates to the technical field of microbial preparation mixing equipment, specifically a mixing device for ammonia nitrogen degradation microbial preparations. Background Technology

[0002] In the field of wastewater treatment and water environment restoration, ammonia nitrogen pollution control has always been a focus of industry attention. Excessive ammonia nitrogen not only leads to eutrophication of water bodies, causing ecological problems such as algal blooms and decreased dissolved oxygen, but may also produce toxic substances that threaten the survival of aquatic organisms and even endanger human health through drinking water sources. Using ammonia nitrogen degradation microbial agents to treat wastewater is one of the methods. Although microbial agents are widely used due to their high efficiency and environmental protection characteristics, existing mixing methods have problems such as lack of synergistic optimization of stirring units, excessive local mixing, and uneven overall mixing.

[0003] To address the aforementioned deficiencies, the prior art (Chinese Patent No. CN218834211U, published on April 11, 2023) provides a mixing device for microbial preparation processing. Through the arrangement of a mounting frame, mixing tank, first control panel, first liquid guide pipe, second liquid guide pipe, second control panel, connecting pipe, pump, drain pipe, and mixing mechanism, it can better mix microbial preparations, facilitating the uniform mixing of large quantities of microbial preparations, reducing the possibility of stratification or precipitation during microbial mixing, and scraping off and mixing small amounts of microorganisms adhering to the inner wall of the mixing tank during the microbial preparation mixing process, thereby improving the quality of microbial preparation mixing and processing.

[0004] In the process of using the above solution, when mixing microorganisms through the stirring component, the movement mode of the stirring component is singular and the stirring direction is singular, which makes it take a long time for the microorganisms to be fully mixed, resulting in low processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a mixing device for ammonia nitrogen degradation microbial preparations, in order to solve the problem mentioned in the background art that the existing microbial preparation mixing devices use a stirring component with a single movement mode and a single stirring direction when mixing microorganisms, which results in the microorganisms taking a long time to be fully mixed and the processing efficiency being low.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for ammonia nitrogen degradation microbial preparations, comprising a mixing cylinder, wherein the top of the mixing cylinder is symmetrically provided with inlets, the bottom surface of the mixing cylinder is provided with an outlet, a motor is installed in the top surface of the mixing cylinder, the output end of the motor is connected to a shaft, the shaft is rotatably connected to the inside of the mixing cylinder, a circular plate is provided on the outer side of the top of the shaft, stirring rods are provided on the circular plate at equal angles, and a scraper is fixed on the outer side of the bottom of the shaft.

[0007] Limiting grooves are formed at equal angles on the circular plate. A stirring rod is slidably connected in the limiting groove. The top of the stirring rod is slidably connected in a guide groove, which is correspondingly formed on the inner top of the mixing cylinder.

[0008] The top of the stirring rod intermittently contacts the first protrusion, which is installed at equal intervals on the inner top of the guide groove.

[0009] Furthermore, the limiting groove on the circular plate is configured as a rectangular structure, the guide groove is configured as a flower-shaped structure, and the stirring rod forms a horizontal reciprocating movement structure through the limiting groove and the guide groove.

[0010] Furthermore, a fixing plate is fixed to the side of the stirring rod, and a movable plate is connected to the bottom of the fixing plate by a first spring. The movable plate is in contact with the top of the circular plate.

[0011] Furthermore, the length of the movable plate is greater than the width of the limiting groove, and the stirring rod forms a vertical sliding structure through the first protrusion, the fixed plate, the first spring and the movable plate, and the first protrusion is provided with a hemispherical structure.

[0012] Furthermore, the scraper is configured with an "L"-shaped structure, and a notch is provided through the outer side of the scraper, in which wiping plates are symmetrically arranged.

[0013] Furthermore, the wiping plate is connected to the inner wall of the recess via a second spring, and both the wiping plate and the scraper are in close contact with the inner wall of the mixing cylinder.

[0014] Furthermore, the top of the wiping plate intermittently presses against the second protrusion, which is installed at an equal angle on the inner wall of the mixing cylinder. The wiping plate, the second spring, and the second protrusion constitute a movable scraping structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This ammonia nitrogen degradation microbial preparation mixing device, during use, has a stirring rod that rotates circumferentially while moving horizontally back and forth, thereby improving the mixing efficiency of horizontal stirring. In addition, while stirring horizontally, the stirring rod also produces vertical displacement, thereby further improving the uniformity of mixing the microbial preparation and increasing the mixing efficiency. Furthermore, it can scrape and clean the inner wall of the device, reducing preparation residue.

[0016] Furthermore, the microbial preparation is added through the feed inlet at the top of the mixing drum. After the motor starts, it drives the shaft to rotate, which in turn drives the circular plate to rotate synchronously. The circular plate drives the stirring rod to rotate circumferentially, mixing the microbial preparation horizontally. While the stirring rod rotates with the circular plate, it also moves horizontally back and forth with the cooperation of the limiting groove and the guide groove, thereby increasing the mixing amplitude and efficiency. At the same time, the top of the stirring rod intermittently contacts the first protrusion, causing the stirring rod to slide vertically, thereby improving the uniformity of the microbial preparation mixture and ensuring full contact.

[0017] Furthermore, when the circular plate drives the stirring rod to rotate, the stirring rod, guided by the guide groove and limited by the limiting groove, can only move in a straight line. This allows the stirring rod to open and close while rotating circumferentially, thereby increasing the mixing methods and improving mixing efficiency. When the stirring rod slides along the guide groove, it intermittently contacts the first protrusion in the guide groove, causing the movable plate on the outside of the stirring rod to move down and contact the top of the circular plate. This causes the fixing plate to compress the first spring. When the top of the stirring rod is misaligned with the first protrusion, the first spring will drive the stirring rod to move upward and reset, allowing the stirring rod to move vertically, thus making the mixing of the microbial preparation more uniform and efficient.

[0018] Furthermore, when the shaft rotates, it drives the scraper to rotate synchronously, thereby cleaning the material remaining on the inner wall of the mixing drum. After the scraper rotates, it will drive the wiping plate in the recess to rotate as well. After the wiping plate rotates, its top will intermittently press and abut against the second protrusion, thereby causing the wiping plate to compress the second spring and slide in the recess. When the wiping plate and the second protrusion are misaligned, the second spring will drive the wiping plate to reset. This process repeats, so that when the scraper rotates, the wiping plate will also move back and forth to scrape, thereby further reducing material residue. Attached Figure Description

[0021] 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.

[0022] Example 1: Please refer to Figures 1-2 The present invention provides the following technical solution: a mixing device for ammonia nitrogen degradation microbial preparation, comprising a mixing cylinder 1, a feed inlet 2 symmetrically opened at the top of the mixing cylinder 1, a discharge outlet 3 provided at the center of the bottom surface of the mixing cylinder 1, a motor 4 installed at the center of the top surface of the mixing cylinder 1, a shaft 5 connected to the output end of the motor 4, the shaft 5 being rotatably connected to the inside of the mixing cylinder 1, a circular plate 6 provided on the outer side of the top of the shaft 5, a stirring rod 8 provided at equal angles on the circular plate 6, a scraper 14 fixed on the outer side of the bottom of the shaft 5, a limiting groove 7 provided at equal angles on the circular plate 6, a stirring rod 8 slidably connected in the limiting groove 7, the top of the stirring rod 8 being slidably connected in the guide groove 9, the guide groove 9 being correspondingly opened at the top of the inner side of the mixing cylinder 1, the top of the stirring rod 8 intermittently contacting a first protrusion 10, the first protrusion 10 being installed at equal intervals at the top of the inner side of the guide groove 9.

[0023] In use, the microbial preparation is added through the feed inlet 2 at the top of the mixing cylinder 1. After the motor 4 is started, it will drive the shaft 5 to rotate. The rotation of the shaft 5 will drive the circular plate 6 to rotate synchronously. The circular plate 6 will drive the stirring rod 8 to rotate circumferentially, stirring and mixing the microbial preparation in a horizontal direction. While the stirring rod 8 rotates with the circular plate 6, it will also move horizontally back and forth with the cooperation of the limiting groove 7 and the guide groove 9, thereby increasing the mixing amplitude and mixing efficiency. At the same time, the top of the stirring rod 8 will intermittently contact the first protrusion 10, thereby causing the stirring rod 8 to slide vertically, thereby improving the uniformity of the microbial preparation mixing and ensuring full contact. Example 1

[0024] Based on Embodiment 1, a fixed plate 11, a first spring 12, and a movable plate 13 are also disclosed. Please refer to [reference needed]. Figures 2-4 As shown, its specific structure is as follows: the limiting groove 7 on the circular plate 6 is set as a rectangular structure, the guide groove 9 is set as a flower-shaped structure, the stirring rod 8 forms a horizontal reciprocating movement structure through the limiting groove 7 and the guide groove 9, the side of the stirring rod 8 is fixed with a fixing plate 11, the bottom of the fixing plate 11 is connected to a movable plate 13 through a first spring 12, the movable plate 13 contacts the top of the circular plate 6, the length of the movable plate 13 is greater than the width of the limiting groove 7, the stirring rod 8 forms a vertical sliding structure through the first protrusion 10, the fixing plate 11, the first spring 12 and the movable plate 13, the first protrusion 10 is set with a hemispherical structure.

[0025] During use, when the circular plate 6 drives the stirring rod 8 to rotate, the stirring rod 8, guided by the guide groove 9 and limited by the limiting groove 7, can only move in a straight line. This allows the stirring rod 8 to open and close while rotating in the circumferential direction, thereby increasing the mixing methods and improving mixing efficiency. When the stirring rod 8 slides along the guide groove 9, it will intermittently contact the first protrusion 10 in the guide groove 9, causing the movable plate 13 on the outside of the stirring rod 8 to move down and contact the top of the circular plate 6. This causes the fixing plate 11 to compress the first spring 12. When the top of the stirring rod 8 is misaligned with the first protrusion 10, the first spring 12 will drive the stirring rod 8 to move up and reset, allowing the stirring rod 8 to move vertically, thus making the microbial preparation more uniform and efficient to mix. Example 2

[0026] Based on Embodiment 2, a second spring 17 and a second protrusion 18 are also disclosed. Please refer to [link / reference]. Figures 5-6As shown, its specific structure is as follows: the scraper 14 is set in an "L" shape, and a notch 15 is opened through the outer side of the scraper 14. A wiping plate 16 is symmetrically arranged in the notch 15. The wiping plate 16 is connected to the inner wall of the notch 15 through the second spring 17. Both the wiping plate 16 and the scraper 14 are in close contact with the inner wall of the mixing cylinder 1. The top of the wiping plate 16 intermittently presses against the second protrusion 18. The second protrusion 18 is installed at an equal angle on the inner wall of the mixing cylinder 1. The wiping plate 16, the second spring 17 and the second protrusion 18 constitute a movable scraping structure.

[0027] During use, when the shaft 5 rotates, it drives the scraper 14 to rotate synchronously, thereby cleaning the material remaining on the inner wall of the mixing cylinder 1. After the scraper 14 rotates, it will drive the wiping plate 16 in the recess 15 to rotate as well. After the wiping plate 16 rotates, its top will intermittently press and abut against the second protrusion 18, thereby causing the wiping plate 16 to compress the second spring 17 and slide in the recess 15. When the wiping plate 16 and the second protrusion 18 are misaligned, the second spring 17 drives the wiping plate 16 to reset. This process is repeated, so that when the scraper 14 rotates, the wiping plate 16 will also move back and forth to scrape, thereby further reducing material residue.
