Description

Technical Field

[0001] This invention relates to the field of homogenization equipment technology, and more specifically to a high-precision homogenizer. Background Technology

[0002] A homogenizer is an industrial device that uses mechanical action to achieve uniform mixing of pharmaceuticals. It is widely used in food processing, biopharmaceuticals, chemical materials, and daily chemical care products. Its core function is to refine material particles to the nanoscale through high pressure, shearing, and impact forces, thereby improving the stability and uniformity of the product. The core working component of a high-pressure homogenizer is the homogenizing valve, which has a precise structure and extremely small fitting clearance (typically less than 0.1 mm). When material passes through this tiny annular gap under high pressure, it experiences a strong shearing force due to the velocity gradient. Simultaneously, upon instantaneous depressurization, it impacts the impact ring at high speed. Combined with the cavitation effect, this achieves homogenization, pulverization, and emulsification of the material.

[0003] However, when high-pressure homogenizers are used in pharmaceutical applications, the high-speed impact of the drug with the impact ring during the homogenization process generates a large amount of heat. This raises the temperature inside the homogenizing valve and on the impact ring, making the drug more susceptible to inactivation and adhesion to the impact ring or inside the homogenizing valve. This reduces the mixing quality of the homogenizing valve. Simultaneously, the increased temperature can cause the impact ring to expand to some extent. Furthermore, because the homogenizing valve has an extremely precise structure with very small clearances, even a slight deformation of the impact ring can easily alter the clearances, making it difficult for the drug to pass through or even causing blockage. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a high-precision homogenizer to solve the problem that when existing high-pressure homogenizers are applied to pharmaceutical preparations, the high-speed impact of the drug with the impact ring during the homogenization process generates a large amount of heat, causing the temperature inside the homogenizing valve and the impact ring to rise. This makes the drug more likely to be deactivated and adhere more easily to the impact ring or the homogenizing valve, thereby reducing the mixing quality of the homogenizing valve. At the same time, the temperature rise can easily cause the impact ring to expand to a certain extent. Since the homogenizing valve has an extremely precise structure with very small gaps, even a very small deformation of the impact ring can easily cause changes in the gaps, making it difficult for the drug to pass through the gaps or even causing blockage.

[0005] This invention is achieved through the following technical solution: A high-precision homogenizer includes a plunger pump and a homogenizing valve. The plunger pump is connected to one end of the homogenizing valve. The homogenizing valve includes a valve body, a valve core, an impact ring, and a drive unit. The valve body is hollow, forming a cavity. The output end of the plunger pump communicates with the cavity. The impact ring is connected to the end of the cavity that communicates with the output end of the plunger pump, and the impact ring and the output end of the plunger pump are coaxially arranged. The inner wall of the impact ring is frustum-shaped, and the end with the smaller radius of the inner wall of the impact ring faces the end where the plunger pump is located. The valve core includes a sliding block and a mating block. The mating block and the sliding block are both coaxially arranged with the impact ring. The mating block is frustum-shaped and fits into the inner wall of the impact ring. The end of the sliding block away from the plunger pump can be slidably connected to the cavity along the direction towards or away from the plunger pump, and the other end is connected to the mating block. The drive unit is used to push the sliding block to slide according to temperature changes.

[0006] Furthermore, the drive unit includes a first temperature sensor, a second temperature sensor, a hydraulic rod, a sliding rod, and a controller. The end of the cavity away from the plunger pump is recessed inward to form a sliding groove. The end of the sliding block away from the plunger pump is slidably fitted into the sliding groove. The end of the fitting block facing the sliding groove is recessed inward to form a receiving cavity. The first temperature sensor is disposed in the receiving cavity. The output end of the hydraulic rod is connected to the bottom wall of the receiving cavity. The sliding rod is coaxially arranged with the impact ring and passes through both ends of the sliding block to connect to the base of the hydraulic rod. The impact ring is provided with a second temperature sensor. The controller is electrically connected to the first temperature sensor, the second temperature sensor, and the hydraulic rod. The controller is used to control the extension and retraction of the hydraulic rod after receiving the temperatures from the first temperature sensor and the second temperature sensor.

[0007] Furthermore, the controller includes a calculation module, a conversion module, and an execution module: The calculation module is used to receive temperature data from the first sensor and the second sensor and calculate the expansion coefficients of the impact ring and the mating block respectively based on the temperature data, and then send the calculation results to the conversion module. The conversion module receives data from the calculation module, integrates the expansion data of the impact ring and the mating block, calculates the data that the mating block needs to move, and then sends the calculation results to the execution module. The execution module receives data from the conversion module and controls the extension and retraction of the hydraulic rod based on the data.

[0008] Furthermore, the side wall of the mating block is provided with a clearing section, which mates with the inner wall of the impact ring. It also includes a motor, which is connected to the bottom wall of the sliding cavity, and the output end of the motor is connected to the sliding block. The controller also includes a control module, which is electrically connected to the motor. The control module is used to receive data from the conversion module and control the speed of the motor after calculating the data from the conversion module.

[0009] Furthermore, the sliding block is provided with a first water inlet and a first water outlet along its length, both of which are connected to the two end faces of the sliding block. The mating block is provided with a first through hole, which is located between the receiving cavity and the side wall of the mating block, and both ends of the first through hole are connected to the first water inlet and the first water outlet, respectively. The valve body side wall is connected to the sliding groove and is provided with a second water inlet and a second water outlet, respectively. The impact ring is provided with a second through hole, which is connected to the second water inlet and the second water outlet. The system also includes a pumping unit and a water tank. The first water inlet, the first water outlet, the second water inlet, and the second water outlet are all connected to the water tank. The pumping unit is used to draw water from the water tank into the first water inlet and the second water inlet.

[0010] Furthermore, the pumping unit includes a first gear, a second gear, a turbine, and a rotating shaft. The first gear is connected to the output end of the motor. A sliding sleeve is connected to the end of the sliding block away from the plunger pump. The sliding sleeve is fitted onto the outer circumferential surface of the sliding rod. The sliding sleeve is slidably connected to the first gear along its length direction. The cross-section of the outer circumferential surface of the sliding sleeve is non-circular. The rotating shaft is rotatably connected to the bottom wall of the sliding groove. The rotating shaft, the second gear, and the turbine are arranged coaxially. The second gear is connected to the rotating shaft and meshes with the first gear. The turbine is located inside the water tank. The end of the rotating shaft away from the bottom wall of the sliding groove passes through the outer wall of the water tank, enters the water tank, and connects to the turbine.

[0011] Furthermore, the end of the sliding block away from the plunger pump is recessed inward to form a first guide groove and a second guide groove. Both the first and second guide grooves are annular and coaxial with the sliding block. The first guide groove is connected to the first water inlet, and the second guide groove is connected to the first water outlet. The end faces of the first and second guide grooves are slidably connected to a first sliding ring and a second sliding ring, respectively. It also includes a first telescopic pipe, a second telescopic pipe, a first guide pipe, and a second guide pipe. One end of the first guide pipe passes through the second sliding ring and is connected to the second guide groove, and the other end is connected to the water tank. The two ends of the second guide pipe are connected to the second water outlet and the water tank, respectively. One end of the first telescopic pipe passes through the first sliding ring and is connected to the first guide groove, and the other end is connected to the water tank. The two ends of the second telescopic pipe are connected to the second water inlet and the water tank, respectively.

[0012] The beneficial effects of this invention are as follows: 1. This high-precision homogenizer, by setting a valve core that can move due to temperature changes, can maintain the slit between the valve core and the impact ring at a suitable distance, reducing the possibility of the impact ring expanding due to temperature rise and causing blockage of the homogenizing valve, thus ensuring the normal operation of the homogenizer to a certain extent.

[0013] 2. This high-precision homogenizer, by setting inlet and outlet water holes, allows coolant to flow into the valve core and impact ring, thereby cooling the valve core and impact ring. This reduces the possibility of the agent being deactivated due to excessively high temperature of the impact ring, and also reduces the possibility of the agent adhering to the high-temperature valve core and impact ring, thus ensuring the production quality of the agent to a certain extent.

[0014] 3. This high-precision homogenizer, by setting a clearing section on the side of the mating block, uses the rotation of the valve core to drive the clearing section to rotate and assist the impact ring to stir, which reduces the possibility of chemical blockage to a certain extent. At the same time, by setting a water pumping section, the rotation of the valve core drives the circulation of coolant, reducing the need for power equipment and reducing energy waste to a certain extent.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Please see Figure 1-2This invention provides a high-precision homogenizer technical solution: a high-precision homogenizer includes a plunger pump 1 and a homogenizing valve 2. The plunger pump 1 is connected to one end of the homogenizing valve 2. The homogenizing valve 2 includes a valve body, a valve core, an impact ring 5, and a drive unit. The valve body has a hollow cavity 31. The output end of the plunger pump 1 communicates with the cavity 31. The impact ring 5 is connected to the end of the cavity 31 that communicates with the output end of the plunger pump 1, and the impact ring 5 is coaxially arranged with the output end of the plunger pump 1. The inner wall of the impact ring 5 is shaped as follows: The valve core, which is shaped like a frustum and has a smaller inner wall radius, faces the end where the plunger pump 1 is located. The valve core includes a sliding block 42 and a mating block 41. Both the mating block 41 and the sliding block are coaxially arranged with the impact ring 5. The mating block 41 is shaped like a frustum and fits into the inner wall of the impact ring 5. The end of the sliding block 42 away from the plunger pump 1 can be slidably connected to the cavity 31 towards or away from the plunger pump 1, and the other end is connected to the mating block 41. The driving part is used to push the sliding block 42 to slide according to the temperature change.

[0020] When using a high-precision homogenizer to mix a reagent according to the present invention, the reagent is first pushed into the homogenizing valve 2 by a plunger pump 1. When the reagent enters the cavity 31 of the homogenizing valve 2, the strong pressure given by the plunger pump 1 causes the reagent to be impacted and dispersed at the end of the mating block 41 facing the plunger pump 1, and then enters the impact ring 5. Through the multi-layer impact structure in the impact ring 5, the reagent is impacted multiple times to obtain a fine reagent with small particles. The high-speed impact of the reagent on the mating block 41 generates heat, and the slit between the mating block 41 and the impact ring 5 generates a large amount of heat, causing the impact ring 5 and the mating block 41 to expand. Since the inner wall of the impact ring 5 is truncated cone-shaped and the end with the smaller radius of the inner wall of the impact ring 5 faces the end where the plunger pump 1 is located, the valve core includes a sliding block 42 and a mating block 41. The mating block 41 and the sliding block are both arranged coaxially with the impact ring 5. The mating block 41 is oriented... The truncated cone-shaped block 41 fits into the inner wall of the impact ring 5. By moving the fitting block 41 away from the plunger pump 1, the slit between the impact ring 5 and the fitting block 41 can be enlarged, making it easier for the drug dispersed by the impact to flow out through the slit. This reduces the possibility of the drug clogging the homogenizing valve 2 due to the expansion of the impact ring 5 causing the slit to become smaller. Since the sliding block 42 can be slidably connected to the cavity 31 towards or away from the plunger pump 1 at one end and to the fitting block 41 at the other end, the driving unit is used to push the sliding block 42 to slide according to temperature changes. By controlling the sliding distance of the sliding block 42 through temperature changes, the distance between the fitting block 41 and the impact ring 5 is always kept at a distance that allows the drug to pass through without causing excessive drug to pass through the slit without impact. This reduces slit clogging to a certain extent while ensuring the quality of drug mixing.

[0021] With this structure, when the reagent of the high-precision homogenizer of the present invention is mixed, the reagent can smoothly impact the impact ring 5 and then enter the next process through the slit between the impact ring 5 and the mating block 41, reducing the possibility of the reagent clogging the slit, ensuring the safe operation of the equipment, and ensuring the production quality of the reagent. In this embodiment: the drive unit includes a first temperature sensor, a second temperature sensor, a hydraulic rod 61, a sliding rod 62, and a controller. The end of the cavity 31 away from the plunger pump 1 is recessed inward to form a sliding groove 32. The end of the sliding block 42 away from the plunger pump 1 is slidably fitted into the sliding groove 32. The end of the fitting block 41 facing the sliding groove 32 is recessed inward to form a receiving cavity 411. The first temperature sensor is disposed in the receiving cavity 411. The output end of the hydraulic rod 61 is connected to the bottom wall of the receiving cavity 411. The sliding rod 62 is coaxially arranged with the impact ring 5 and the two ends of the sliding rod 62 pass through the sliding block 42 and are connected to the base of the hydraulic rod 61. The impact ring 5 is provided with a second temperature sensor. The controller is electrically connected to the first temperature sensor, the second temperature sensor, and the hydraulic rod 61. The controller is used to control the extension and retraction of the hydraulic rod 61 after receiving the temperatures from the first temperature sensor and the second temperature sensor.

[0022] Because the cavity 31, at the end furthest from the plunger pump 1, has an inwardly recessed sliding groove 32, the end of the sliding block 42 furthest from the plunger pump 1 can slidably engage with the sliding groove 32. By sliding the sliding block 42 within the sliding groove 32, the end of the sliding block 42 furthest from the plunger pump 1 can be slidably connected to the cavity 31, either towards or away from the plunger pump 1. Since the output end of the hydraulic rod 61 is connected to the bottom wall of the receiving cavity 411, and the sliding rod 62 is coaxially arranged with the impact ring 5 and passes through both ends of the sliding block 42 to connect to the base of the hydraulic rod 61, the extension and retraction of the hydraulic rod 61 can drive the sliding block 42 to slide within the sliding groove 32. Since the controller is electrically connected to the first temperature sensor, the second temperature sensor, and the hydraulic rod 61, the controller receives the temperatures from the first and second temperature sensors and then controls the extension and retraction of the hydraulic rod 61, causing the first... When the temperature sensor and the second temperature sensor sense an increase in temperature, they control the hydraulic rod 61 to shorten, causing the sliding block 42 to slide towards the sliding groove 32. This moves the side wall of the mating block 41 away from the inner wall of the impact ring 5, ensuring that the gap between the inner wall of the mating block 41 and the impact ring 5 remains within a suitable distance even when the mating block 41 and the impact ring 5 expand. When the temperature sensor and the first temperature sensor sense a decrease in temperature, they control the hydraulic rod 61 to extend, causing the sliding block 42 to slide away from the sliding groove 32. This moves the side wall of the mating block 41 closer to the inner wall of the impact ring 5, ensuring that the gap between the inner wall of the mating block 41 and the impact ring 5 remains within a suitable distance even when the expansion of the mating block 41 and the impact ring 5 weakens and returns to normal temperature. The telescopic rod can extend or retract the hydraulic rod 61 to different lengths according to temperature changes. With this structure, the drive unit can be used to push the sliding block 42 to slide according to temperature changes.

[0023] In this embodiment: the controller includes a calculation module, a conversion module, and an execution module. The calculation module is used to receive temperature data from the first sensor and the second sensor and calculate the expansion coefficients of the impact ring 5 and the mating block 41 respectively based on the temperature data, and then send the calculation results to the conversion module. The conversion module is used to receive data from the calculation module and integrate the expansion data of the impact ring 5 and the mating block 41 to calculate the data that the mating block 41 needs to move. Then, the calculation results are sent to the execution module. The execution module is used to receive data from the conversion module and control the extension and retraction of the hydraulic rod 61 according to the data.

[0024] The controller receives temperature data from the first and second sensors via a calculation module, calculates the expansion coefficients of the impact ring 5 and the mating block 41 respectively, determines the expansion data, and sends the expansion data to the conversion module. The conversion module integrates the expansion data of the impact ring 5 and the mating block 41, calculates the data that the mating block 41 needs to move, and sends it to the execution module. After receiving the data from the conversion module, the execution module controls the extension and retraction of the hydraulic rod 61. With this structure, the controller can be used to receive the temperatures from the first and second temperature sensors and then control the extension and retraction of the hydraulic rod 61.

[0025] In this embodiment: the side wall of the mating block 41 is provided with a clearing part, which mates with the inner wall of the impact ring 5. It also includes a motor 8, which is connected to the bottom wall of the sliding cavity. The output end of the motor 8 is connected to the sliding block 42. The controller also includes a control module, which is electrically connected to the motor 8. The control module is used to receive data from the conversion module and control the speed of the motor 8 after calculating the data from the conversion module.

[0026] Since the unblocking part is fitted with the inner wall of the impact ring 5, and the motor 8 is connected to the bottom wall of the sliding cavity, and the output end of the motor 8 is connected to the sliding block 42, the rotation of the motor 8 can drive the sliding block 42 to rotate, thereby causing the unblocking part to rotate relative to the impact ring 5, thus agitating the agent, facilitating the agent to pass through the slit and reducing the possibility of agent blockage; since the motor 8 is electrically connected to the control module, the control module is used to receive data from the conversion module and calculate and control the speed of the motor 8, so that the rotation of the motor 8 can change according to the temperature data received by the first temperature sensor and the second temperature sensor. When the temperature data received by the first temperature sensor and the second temperature sensor is high, the control module controls the speed of the motor 8 to increase, so that the agent can pass through faster and reduce the possibility of the agent staying at high temperature and thus becoming inactive; when the temperature data received by the first temperature sensor and the second temperature sensor decreases, the control module controls the speed of the motor 8 to decrease, so that the agent stays and impacts more fully, which to a certain extent ensures the quality of the agent while avoiding over-design.

[0027] In this embodiment: the sliding block 42 is provided with a first water inlet 421 and a first water outlet 422 along its length. Both the first water inlet 421 and the first water outlet 422 are connected to both end faces of the sliding block 42. The mating block 41 is provided with a first through hole 423, which is located between the receiving cavity 411 and the side wall of the mating block 41, and both ends of the first through hole 423 are connected to the first water inlet 421 and the first water outlet 422, respectively. The valve body side wall and the sliding groove... The 32 connection is respectively provided with a second water inlet 33 and a second water outlet 34. The impact ring 5 is provided with a second through hole 35, which is connected to the second water inlet 33 and the second water outlet 34. It also includes a water pumping unit 9 and a water tank 10. The first water inlet 421, the first water outlet 422, the second water inlet 33 and the second water outlet 34 are all connected to the water tank 10. The water pumping unit 9 is used to pump water from the water tank 10 into the first water inlet 421 and the second water inlet 33.

[0028] The connection between the first inlet hole 421, the first through hole 423, and the first outlet hole 422 allows coolant to flow through the first inlet hole 421 and the first through hole 423 to the mating block 41, and then out through the first outlet hole 422. In this way, the flowing coolant can cool the mating block 41 and reduce its expansion under certain conditions. Similarly, the connection between the second inlet hole 33, the second through hole 35, and the second outlet hole 34 allows coolant to flow through the second inlet hole 33 and the second through hole 35 to the impact ring 5, and then out through the second outlet hole 34. This also allows the flowing coolant to cool the impact ring 5. Cooling is achieved, which reduces the expansion of the impact ring 5 under certain conditions. Since the first water inlet 421, the first water outlet 422, the second water inlet 33, and the second water outlet 34 are all connected to the water tank 10, the pumping unit 9 is used to draw water from the water tank 10 into the first water inlet 421 and the second water inlet 33. The coolant can circulate between the water tank 10 and the first water inlet 421, the first water outlet 422, the second water inlet 33, and the second water outlet 34, thereby cooling the mating block 41 and the impact ring 5. This reduces the possibility of the agent becoming inactive due to excessive temperature of the mating block 41 and the impact ring 5, thus ensuring the production quality of the agent.

[0029] In this embodiment: the pumping unit 9 includes a first gear 91, a second gear 92, a turbine 93, and a rotating shaft 94. The first gear 91 is connected to the output end of the motor 8. The end of the sliding block 42 away from the plunger pump 1 is connected to a sliding sleeve 43. The sliding sleeve 43 is sleeved on the outer circumferential surface of the sliding rod 62. The sliding sleeve 43 can slide along its length direction to connect to the first gear 91. The cross-section of the outer circumferential surface of the sliding sleeve 43 is non-circular. The rotating shaft 94 is rotatably connected to the bottom wall of the sliding groove 32. The rotating shaft 94, the second gear 92, and the turbine 93 are arranged on the same axis. The second gear 92 is connected to the rotating shaft 94 and meshes with the first gear 91. The turbine 93 is located inside the water tank 10. The end of the rotating shaft 94 away from the bottom wall of the sliding groove 32 passes through the outer wall of the water tank 10 and enters the water tank 10 and connects to the turbine 93.

[0030] Since the first gear 91 is connected to the output end of the motor 8, the rotation of the gear can drive the first gear 91 to rotate. Since the end of the sliding block 42 away from the plunger pump 1 is connected to the sliding sleeve 43, and the sliding sleeve 43 is sleeved on the outer peripheral surface of the sliding rod 62, the cross-section of the outer peripheral surface of the sliding sleeve 43 is non-circular. When the first gear 91 rotates, it can drive the sliding sleeve 43 to rotate, thereby driving the sliding block 42 to rotate. Since the sliding sleeve 43 can be slidably connected to the first gear 91 along its length direction, the first gear 91 can drive the sliding block 42 to rotate without affecting the sliding of the sliding block 42 relative to the sliding groove 32.

[0031] Since the rotating shaft 94 is rotatably connected to the bottom wall of the sliding groove 32, the rotating shaft 94, the second gear 92, and the turbine 93 are arranged on the same axis. The second gear 92 is connected to the rotating shaft 94 and meshes with the first gear 91. The rotation of the first gear 91 can drive the second gear 92 to rotate, thereby driving the rotating shaft 94 to rotate. Since the turbine 93 is located inside the water tank 10, one end of the rotating shaft 94 away from the bottom wall of the sliding groove 32 passes through the outer wall of the water tank 10 and enters the water tank 10 and connects to the turbine 93. The rotation of the rotating shaft 94 can drive the turbine 93 to rotate, thereby driving the coolant in the water tank 10 into the first water inlet 421 and the second water inlet 33.

[0032] Because the control module can control the motor 8 to increase its rotation speed when the temperature of the mating block 41 and the impact ring 5 rises, the motor can increase the speed of the first gear 91, thereby increasing the speed of the turbine 93. This allows the coolant in the water tank 10 to enter the first water inlet 421 and the second water inlet 33 more quickly, accelerating the coolant circulation and enhancing the cooling effect. With this structure, when the temperature of the mating block 41 and the impact ring 5 rises, the motor 8 can drive the unblocking part to accelerate the stirring of the agent while accelerating the coolant circulation. To a certain extent, this ensures that the homogenizer can operate stably at a suitable temperature, thereby ensuring the production quality of the agent.

[0033] In this embodiment: the end of the sliding block 42 away from the plunger pump 1 is recessed inward to form a first guide groove 424 and a second guide groove 425. Both the first guide groove 424 and the second guide groove 425 are annular and coaxially arranged with the sliding block 42. The first guide groove 424 is connected to the first water inlet 421, and the second guide groove 425 is connected to the first water outlet 422. The end faces of the first guide groove 424 and the second guide groove 425 are slidably connected to a first sliding ring 426 and a second sliding ring 427, respectively. It also includes a first telescopic pipe 428, a second telescopic pipe 429, a first guide pipe 101 and a second guide pipe 102. One end of the first guide pipe 101 passes through the second sliding ring 427 and is connected to the second guide groove 425, and the other end is connected to the water tank 10. The two ends of the second guide pipe 102 are connected to the second water outlet 34 and the water tank 10, respectively. One end of the first telescopic pipe 428 passes through the first sliding ring 426 and is connected to the first guide groove 424, and the other end is connected to the water tank 10. The two ends of the second telescopic pipe 429 are connected to the second water inlet 33 and the water tank 10, respectively.

[0034] Since one end of the first guide pipe 101 passes through the second sliding ring 427 and connects to the second guide groove 425, and the other end connects to the water tank 10, and one end of the first telescopic pipe 428 passes through the first sliding ring 426 and connects to the first guide groove 424, and the other end connects to the water tank 10, specifically, the water tank 10 can be divided into a front part where the pumping part 9 is placed and moves with the sliding block 42, and a rear part mainly for storing water. The front and rear parts are connected, and water can flow from the rear to the front. The water in the water tank 10 can be drawn by the pumping part 9, enter the first guide groove 424 through the first telescopic pipe 428, and then enter the first water inlet 421. When the water enters the first water inlet 421, it flows through the first through hole 423 and the first water outlet 422 and then enters the second guide groove 425, and then enters the water tank 10 through the first guide pipe 101. In this way, the water circulation of the cooperating block 41 can be realized.

[0035] Since both the first guide channel 424 and the second guide channel 425 are annular and coaxially arranged with the sliding block 42, the end faces of the first guide channel 424 and the second guide channel 425 are slidably connected to the first sliding ring 426 and the second sliding ring 427, respectively. The rotation of the sliding block 42 will not drive the first sliding ring 426 and the second sliding ring 427 to rotate, so that the rotation of the sliding block 42 will not affect the coolant entering the first guide channel 424. Since the first sliding ring 426 is connected to the first telescopic tube 428 and the second water inlet 33 is connected to the second telescopic tube 429, when the sliding block 42 slides along the sliding channel 32, the first telescopic tube 428 and the second telescopic tube 429 change their length and shape with the movement of the sliding block 42, so as not to affect the coolant entering the first guide channel 424. In this way, the operation of the pumping unit 9 and the operation of the sliding block 42 can be made independent of each other, so that the high-precision homogenizer of the present invention can maintain normal operation.

[0036] Since the two ends of the second guide pipe 102 are connected to the second outlet 34 and the water tank 10 respectively, and the two ends of the second telescopic pipe 429 are connected to the second inlet 33 and the water tank 10 respectively, the water in the water tank 10 can be drawn by the pumping unit 9 and enter the second inlet 33 through the second telescopic pipe 429. After entering the second inlet 33, the water flows through the second through hole 35 and the second outlet 34, and then enters the water tank 10 through the second guide pipe 102. In this way, the water circulation of the impact ring 5 can be realized. The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
