Description

Technical Field

[0001] The present application relates to the technical field of experimental instruments and equipment, mainly to a stator and rotor mounting structure and a dispersion head structure. Background Art

[0002] The laboratory high shear homogenizer, also known as high shear disperser or high shear homogenizing emulsifier, is composed of a high-speed motor, a transmission system, a dispersing head, etc. The stator part of the dispersing head needs to be fixedly connected to the equipment body. Its working principle is that the motor drives the dispersing head rotor to rotate at a high speed, and the narrow gap between the stator and the rotor at the bottom of the dispersing head forms a high linear speed relative movement between the rotor and the stator, achieving the effects of high shear homogenization, dispersion, and emulsification of fluid materials. The speed of the rotor usually needs to reach 20,000 revolutions per minute (rpm), requiring the installation and connection of the stator and rotor to be safe and reliable. Since the dispersing head consists of a stator and a rotor, the stator part must be fixedly connected to the body, and the rotor part needs to be reliably connected to the connecting device of the motor shaft, so the installation process is generally complicated. However, since the dispersing head needs to be disassembled, cleaned, or even sterilized, the installation of the dispersing head is often required to be simple and fast.

[0003] There are generally three ways to install traditional dispersers. One is to use lateral bolts to fix the stator through the screw holes. This method requires the aperture accuracy of the stator installation part to be high enough to avoid excessive errors in the axial position of the stator caused by the lateral bolt fixation. This installation method must be operated with both hands, one hand to fix the stator position and the other hand to tighten the bolts, which is not very convenient to install. The second method is to connect the outer part of the stator to the body with threads. It is generally used on small dispersers with a small diameter of the disperser head. The tightening of the threads also generally requires two hands to operate. The rotor is not easy to align during the tightening process. The installation process requires training and has a certain degree of difficulty. The third method is to use a screw lock method to fix the rotor with two pin protrusions on the inside of the installation hole through spiral clamping. The screw process also has high requirements for the alignment of the rotor. Generally, it also requires two hands to operate, and the processing accuracy of the screw part is high. If the processing error is large, jamming and other faults may occur. The second and third installation methods both require relative rotation between the host and the disperser head. When the host cannot be fixed, the disperser head can be installed in a linear plug-in manner in the axial direction. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

They are not used to limit the conditions under which the present invention can be implemented, and therefore have no substantive technical significance. Any structural modification, change in proportion or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical contents disclosed by the present invention.

[0031] The directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "middle", "longitudinal", "lateral", "horizontal", "inner", "outer", "radial", "circumferential" and the like in this specification are based on the directions or positional relationships shown in the drawings and are only for the convenience of simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In order to realize the rapid disassembly and assembly of the stator and rotor, Figure 1-3 As shown, the present disclosure provides a stator-rotor mounting structure, including a stator structure 100, a rotor 200, a mounting sleeve 300, a movable sleeve 400, a fixing member 500 and a motor 600. The rotor 200 is mounted on a rotating shaft 610 of the motor 600, and the motor 600 can drive the rotor 200 to rotate. The mounting sleeve 300 is mounted on the motor 600, and the movable sleeve 400 is sleeved outside the mounting sleeve 300, and the movable sleeve 400 can move between a first position and a second position relative to the mounting sleeve 300. A first accommodating groove 410 is formed on the movable sleeve 400, and a second accommodating groove 320 is formed on the mounting sleeve 300 to accommodate the fixing member 500. When the movable sleeve 400 is located at the first position, the movable sleeve 400 abuts against the fixing member 500, so that the fixing member 500 cooperates with the stator structure 100, so that the stator structure 100 is mounted on the mounting sleeve 300. When the movable sleeve 400 is located at the second position, the first receiving groove 410 of the movable sleeve 400 corresponds to the fixing member 500, so that the fixing member 500 can be partially located in the first receiving groove 410, so that the stator structure 100 can be released from the fixing member 500 to detach from the installation sleeve 300.

[0033] Specifically, if Figure 4-7 and Fig.10As shown, the installation sleeve 300 is formed with a first channel 310 for the stator structure 100 to enter, and a limiting portion 321 is formed in the second receiving groove 320, and the limiting portion 321 is used to limit the fixing member 500 from leaving the second receiving groove 320 and entering the first channel 310. In addition, the limiting portion 321 is formed with a first through hole 322, and a part of the fixing member 500 can protrude from the first through hole 322 and enter the first channel 310. The part of the fixing member 500 can protrude from the first through hole 322 to enter the first channel 310 and cooperate with the stator structure 100 to limit the stator structure 100 from leaving the installation sleeve 300. For the stator structure 100, it includes a stator 120 and a stator sleeve 110, and the stator sleeve 110 is fixedly connected to the stator 120, and a third receiving groove 111 is formed on the stator sleeve 110 to accommodate a part of the fixing member 500. More specifically, when the fixing member 500 is affected by the movable sleeve 400 and protrudes from the first through hole 322 and the stator sleeve 110 has not yet been inserted into the first passage 310, the fixing member 500 will hinder the stator sleeve 110 and the stator 120, so that the stator sleeve 110 cannot be installed in the first passage 310. When the fixing member 500 is affected by the movable sleeve 400 and protrudes from the first through hole 322 and the stator sleeve 110 enters the first passage 310, the third receiving groove 111 of the stator sleeve 110 interacts with the fixing member 500, thereby restricting the stator sleeve 110 from detaching from the fixing member 500 and leaving the first passage 310.

[0034] It should be noted that when the movable sleeve 400 is located at the first position, since the first receiving groove 410 of the movable sleeve 400 does not correspond to the fixing member 500, the movable sleeve 400 can press the fixing member 500, so that the fixing member 500 protrudes from the first channel 310 to restrict the stator structure 100 from entering or leaving the installation sleeve 300. However, when the movable sleeve 400 is located at the second position, since the first receiving groove 410 of the movable sleeve 400 corresponds to the fixing member 500, the fixing member 500 can be inserted into the first receiving groove 410, and the stator structure 100 is no longer restricted from leaving the installation sleeve 300. At this time, if the stator structure 100 is located in the first channel 310, when the user pulls out the stator structure 100, the stator structure 100 will push the fixing member 500 outward, allowing the fixing member 500 to leave the third accommodating groove 111, so that the fixing member 500 can be partially located in the first accommodating groove 410, thereby releasing the cooperation between the fixing member 500 and the stator structure 100, so that the stator structure 100 can be pulled out from the first channel 310.

[0035] In order to facilitate the movement of the fixing member 500 , the fixing member 500 may be shaped as a spherical structure.

[0036] Optionally, the stator-rotor mounting structure includes a plurality of fixing members 500, and a plurality of second accommodating grooves 320 are formed on the mounting sleeve 300. It should be noted that the first accommodating groove 410 is circumferentially arranged on the mounting sleeve 300, so one first accommodating groove 410 can accommodate a plurality of fixing members 500. The third accommodating groove 111 is circumferentially arranged on the stator sleeve 110, so one third accommodating groove 111 can accommodate a plurality of fixing members 500. It should be understood that the shapes of the first accommodating groove 410 and the third accommodating groove 111 can be varied, and the present disclosure does not impose any specific limitation.

[0037] Optionally, the stator-rotor mounting structure further includes a fixing seat 800, the fixing seat 800 is fixedly mounted on the motor 600, and the mounting sleeve 300 is threadedly connected to the fixing seat 800. Specifically, the stator-rotor mounting structure includes a plurality of guide members 810, and the plurality of guide members 810 extend in the front-to-back direction to limit the moving direction of the movable sleeve 400, so that the movable sleeve 400 can only move in the front-to-back direction to move between the first position and the second position. Specifically, the rotor 200 and the stator 120 both extend in the front-to-back direction, and the stator 120 can move backward and be inserted into the first channel 310. In addition, the rotor 200 is mounted on the rotating shaft 610 of the motor 600 through the coupling 700. Specifically, the rear end of the coupling 700 is sleeved on the rotating shaft 610 of the motor 600, the front end of the coupling 700 is formed with a mounting groove, and the rear end of the rotor 200 is formed with a mounting protrusion. The rotor 200 is mounted on the coupling 700 through the cooperation of the mounting protrusion and the mounting groove, and then connected to the rotating shaft 610 of the motor 600. Optionally, a PTFE gasket (polytetrafluoroethylene gasket) is provided in the stator and rotor mounting structure to support the rotor 200 as a bearing, and the rotor 200 cooperates with the PTFE gasket to prevent the rotor 200 from moving forward and leaving the mounting groove. Specifically, the PTFE gasket is surrounded by the mounting sleeve 300, the rotor 200 and the stator sleeve 110, and cannot move normally, but after the stator sleeve 110 and the mounting sleeve 300 are removed, the PTFE gasket can be removed and the rotor 200 can be separated from the coupling 700.

[0038] It should be noted that the installation sleeve 300 and the movable sleeve 400 can be engaged with each other to prevent the movable sleeve 400 in the first position from continuing to move forward to separate from the installation sleeve 300 .

[0039] Optionally, the fixed seat 800 is formed with a plurality of second through holes, the second through holes correspond one-to-one to the guide members 810, the guide members 810 are installed in the corresponding second through holes, the movable sleeve 400 is provided with a plurality of third through holes, the third through holes correspond one-to-one to the guide members 810, the guide members 810 can be inserted into the third through holes, and the spring 820 is sleeved outside the guide member 810 to drive the movable sleeve 400 located at the second position to move to the first position.

[0040] In addition, the present disclosure also provides a dispersion head structure, including a stator and rotor mounting structure, wherein a fourth through hole is formed at the end of the stator 120 away from the motor 600, such as Fig.11 As shown. Specifically, the front end of the rotor 200 is a fork-shaped structure, corresponding to the position of the fourth through hole of the stator 120. When the rotor 200 rotates, the objects between the rotor 200 and the stator 120 are ground and flow out from the fourth through hole of the stator 120, thereby realizing the function of the dispersing head. Since the front end structure of the rotor 200 is various, the present disclosure does not make specific restrictions. It should be noted that the dispersing head structure can be applied to a homogenizer.

[0041] In the process of actually cleaning the front end of the stator 120 and the rotor 200, the user first moves the movable sleeve 400 backward from the first position to the second position, so that the fixing member 500 can be partially located in the first receiving groove 410. At this time, the stator 120 can move forward to disengage from the first channel 310. Specifically, when the stator 120 moves forward, it will push the fixing member 500 outward, so that the fixing member 500 moves outward, and the fixing member 500 will be partially located in the first receiving groove 410 and no longer restrict the stator sleeve 110 and the stator 120 from moving forward. After the stator sleeve 110 and the stator 120 leave the first channel 310, the movable sleeve 400 moves forward under the action of the spring 820, so that the first receiving groove 410 of the movable sleeve 400 no longer corresponds to the fixing member 500, and the movable sleeve 400 abuts against the fixing member 500 again, so that the fixing member 500 is partially protruding from the first through hole 322 and is located in the first channel 310.

[0042] After cleaning the front end of the rotor 200 and the stator 120, first, the movable sleeve 400 is moved backward from the first position to the second position, so that the fixing member 500 can be partially located in the first receiving groove 410, and the fixing member 500 is prevented from restricting the stator sleeve 110 from entering the first channel 310. Then, the stator sleeve 110 and the stator 120 are inserted into the first channel 310, so that the position of the third receiving groove 111 of the stator sleeve 110 corresponds to the fixing member 500, and the fixing member 500 can be partially inserted into the third receiving groove 111. After that, the movable sleeve 400 is released, and the movable sleeve 400 moves from the second position to the first position under the action of the spring 820. At this time, the first receiving groove 410 of the movable sleeve 400 no longer corresponds to the fixing member 500. Under the pressure of the movable sleeve 400, the fixing member 500 moves inward into the third receiving groove 111, thereby achieving the fixation of the stator sleeve 110 and the stator 120.

[0043] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
