Description

Technical Field

[0001] This invention relates to the field of fixing base technology, specifically to a fixing base structure for a stator. Background Technology

[0002] Medical waste refers to waste generated during medical treatment, prevention, and other related activities that possess direct or indirect infectiousness, toxicity, or other hazards. Medical waste may contain large amounts of pathogens, microorganisms, or harmful chemicals, making it a highly dangerous type of waste unlike other types. Improper disposal not only pollutes soil and water bodies but also contributes to air pollution, potentially causing illness and harm to those exposed. The recycling of medical waste requires disinfection and sterilization, which inevitably involves the use of large quantities of disinfectant solutions, which must be disposed of after use.

[0003] In the process of recycling medical wastewater, a rotary valve stator is required to perform functional actions by switching the flow channels. The fixed part of the switching surface is called the stator, and the rotating part is called the rotor. The stator is fixed by four pins on the inner ring of the stator. However, when the stator is fixed by the four pins on the inner ring of the stator, the circumference formed by the pins is small and the torque that can be withstood is also small. The rotary torque generated by the rotary cutting surface can easily make the pin fixing hole larger, which will cause the fixed position of the stator to change and the flow resistance to change. To address this, we propose a stator fixing seat structure. Summary of the Invention

[0004] The purpose of this invention is to provide a stator fixing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stator fixing seat structure, comprising: a stator body;

[0006] A torque amplification mechanism is installed on the outside of the stator body to increase the torque of the stator body and fix the stator body.

[0007] The positioning mechanism consists of four parts, which are located inside the stator body to position the rotor and the stator body that fixes the torque amplification mechanism.

[0008] There are four spring-back mechanisms. The spring-back mechanisms are located at the bottom of the positioning mechanism inside the stator body and control the positioning mechanism inside the stator body.

[0009] Preferably, the outer wall of the stator body is symmetrically provided with four limiting grooves, and the inner ring of the limiting groove is provided with four mutually symmetrical positioning holes.

[0010] Preferably, the bottom of the stator body is provided with an integrally fixed second base, and the lower wall of the second base is provided with an integrally fixed first base.

[0011] Preferably, the torque amplification mechanism includes a fixing hoop with an inner wall diameter that is the same as the outer wall diameter of the stator body, and a mounting slot is provided on one side of the bottom of the fixing hoop.

[0012] Preferably, the inner wall of the fixing hoop is symmetrically provided with four integrated fixing limit strips.

[0013] Preferably, the upper wall of the fixing hoop is symmetrically provided with an integrally fixed torque column.

[0014] Preferably, the positioning mechanism includes a cylindrical fixing pin, a pressure-bearing column is fixedly inserted inside the fixing pin, and an integrally fixed die-cast head is provided on the top of the pressure-bearing column.

[0015] Preferably, four anti-rotation grooves are symmetrically formed on the bottom outer wall of the fixing pin.

[0016] Preferably, the spring mechanism includes a spring seat fixedly connected to the stator body, a spring plate movably disposed inside the spring seat, an integrally fixed push column disposed on the lower wall of the spring plate, and a return spring disposed on the outer wall of the push column.

[0017] Preferably, the bottom center of the rebound seat has a flow divider chamber, and the inner wall of the flow divider chamber has four symmetrical flow divider holes, the output end of which is connected to an air guide.

[0018] This invention has at least the following beneficial effects:

[0019] 1. The present invention can fix the stator body through the torque amplification mechanism and increase the torque bearing capacity of the stator body. At the same time, the positioning mechanism can position the rotor that matches the stator body, thereby ensuring the stability of the installation between the two. Furthermore, the spring mechanism can eject the damaged or broken positioning mechanism upwards for easy removal of the positioning mechanism.

[0020] 2. The four torque pillars of this invention can distribute the torque force from the rotor to the four fixed pins, thereby preventing the fixed pins from breaking under torque force when the rotor rotates. The torque force of the four fixed pins is distributed among the four torque pillars, which can increase the torque force bearing capacity of the entire device. Attached Figure Description

[0030] 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.

[0031] Please see Figure 1-8 The present invention provides a technical solution: Embodiment 1, a stator fixing seat structure, comprising: stator body 1;

[0032] Torque amplification mechanism 2 is disposed outside the stator body 1, which increases the torque of the stator body 1 and fixes the stator body 1.

[0033] Positioning mechanism 3, four positioning mechanisms 3 are provided, and the positioning mechanisms 3 are located inside the stator body 1 to position the rotor and the stator body 1 which is fixed by the torque amplification mechanism 2;

[0034] The spring-back mechanism 4 has four parts. It is located at the bottom of the positioning mechanism 3 inside the stator body 1. It controls the positioning mechanism 3 inside the stator body 1 and installs the torque amplification mechanism 2 on the outside of the stator body 1. The torque amplification mechanism 2 can fix the stator body 1 and increase the torque bearing capacity of the stator body 1. At the same time, the positioning mechanism 3 can position the rotor that matches the stator body 1, thereby ensuring the stability of the installation between the two. The spring-back mechanism 4 can also pop up any damaged or broken positioning mechanism 3, making it easy to remove the positioning mechanism 3.

[0035] The outer wall of the stator body 1 is symmetrically provided with four limiting grooves 14. The inner ring of the limiting grooves 14 is provided with four symmetrical positioning holes 12. The outer ring of the stator body 1 is provided with several fine holes 11 that penetrate the stator body 1 at equal intervals. The center of the stator body 1 is provided with a central hole 13 that penetrates the stator body 1. The bottom of the stator body 1 is provided with an integrally fixed second base 16. The lower wall of the second base 16 is provided with an integrally fixed first base 15. The four limiting strips 24 are inserted into the four limiting grooves 14 to ensure the fixation between the stator body 1 and the fixing hoop 21 and prevent misalignment or rotation when the stator body 1 and the fixing hoop 21 are subjected to the torque force of the rotor, thereby ensuring the stability between the stator body 1 and the fixing hoop 21.

[0036] The torque amplification mechanism 2 includes a fixing hoop 21 with an inner wall diameter that is the same as the outer wall diameter of the stator body 1. A mounting slot 23 is provided on one side of the bottom of the fixing hoop 21. Four integrally fixed limiting strips 24 are symmetrically provided on the inner wall of the fixing hoop 21. The four limiting strips 24 and four limiting slots 14 engage with each other. The four limiting strips 24 and four limiting slots 14 correspond one-to-one. First, the limiting strips 24 and the limiting slots 14 are all aligned with each other. Then, the stator body 1 is installed into the fixing hoop 21. The four limiting strips 24 are inserted into the four limiting slots 14 to prevent misalignment or rotation when the stator body 1 and the fixing hoop 21 are subjected to the torque force of the rotor, thereby ensuring the stability between the stator body 1 and the fixing hoop 21.

[0037] The upper wall of the fixing hoop 21 is symmetrically provided with integrally fixed torque columns 22. The diameter of each of the four torque columns 22 is larger than the diameter of the four fixing pins 31. The four torque columns 22 can share the torque force from the rotor on the four fixing pins 31, thereby preventing the fixing pins 31 from breaking under torque force when the rotor rotates. The torque force of the four fixing pins 31 is shared by the four torque columns 22, which can increase the torque force bearing capacity of the entire device.

[0038] The positioning mechanism 3 includes a cylindrical fixing pin 31, with a pressure-bearing column 32 fixedly inserted inside the fixing pin 31. The top of the pressure-bearing column 32 is provided with an integrally fixed die-cast head 33. The bottom outer wall of the fixing pin 31 is symmetrically provided with four anti-rotation grooves 34. The four fixing pins 31 are inserted into the four positioning holes 12 to facilitate the use and installation of the rotor that matches the stator body 1. At the same time, the pressure-bearing column 32 that penetrates the fixing pin 31 can increase the torque force that the fixing pin 31 can withstand, reducing the probability of disconnection or damage.

[0039] According to the above embodiment, the springback mechanism 4 includes a springback seat 41 fixedly connected to the stator body 1. A springback plate 42 is movably disposed inside the springback seat 41. The springback plate 42 moves up and down in the inner hole 405 of the springback mechanism 4. The diameter of the inner hole 405 is the same as the diameter of the positioning hole 12 and they are aligned with each other. A slag-proof ring 404 with the same diameter as the inner hole 405 is glued to the outer wall of the springback plate 42. An integrally fixed pusher 43 is provided on the lower wall of the springback plate 42. The outer wall of the pusher 43 is provided with a composite... When installing the fixing pins 31, the four fixing pins 31 need to be inserted into the positioning holes 12 in sequence, so that the bottom of the fixing pins 31 is inserted into the inner hole 405 inside the spring seat 41. Thus, by extending the fixing pins 31 downward, the bottom of the fixing pins 31 can squeeze the spring plate 42, thereby causing the spring plate 42 and the push column 43 to move downward. As a result, the push column 43 moves downward in the air pushing pipe 402, which can squeeze the gas in the air pushing pipe 402 into the diversion chamber 44.

[0040] The bottom center of the rebound seat 41 has a diversion chamber 44. Above the diversion chamber 44 is a thrust pipe 402 with the same diameter as the push column 43. The push column 43 moves up and down inside the thrust pipe 402. The inner wall of the diversion chamber 44 has four symmetrical diversion holes 403. The output end of the diversion hole 403 is connected to a guide pipe 46. The output end of each of the four guide pipes 46 is provided with an identical pressurization chamber 47. The inner side of the pressurization chamber 47 has a telescopic opening 401 aligned with the anti-rotation groove 34. Inside the telescopic opening 401 is an anti-rotation buckle 48 that matches the size of the anti-rotation groove 34. The inner wall of the anti-rotation buckle 48 is fixed with a sealing plate 49. The gas squeezed into the diversion chamber 44 exits through the four diversion holes 403 and Four air ducts 46 are respectively injected into different pressurized chambers 47. At the same time, the pressure inside the pressurized chamber 47 increases, which can push the anti-rotation buckle 48 outward from the telescopic port 401. The sealing plate 49 prevents gas leakage. The extended anti-rotation buckle 48 can be locked into the anti-rotation groove 34. In this way, the fixed pin 31 is prevented from rotating during the operation of the entire device. After the fixed pin 31 is disconnected, the spring force of the return spring 45 on the outer wall of the push column 43 can make the spring plate 42 spring back upward. At the same time, the gas in the pressurized chamber 47 flows back into the diversion chamber 44. In this way, the pressure in the pressurized chamber 47 decreases, which can reset the anti-rotation buckle 48. Thus, the spring plate 42 can push the fixed pin 31 that is disconnected in the positioning hole 12 upward out of the positioning hole 12.
