Description

Technical Field

[0001] This utility model relates to the field of resin mixing device technology, and more specifically, to a magnetically levitated high-pressure resin mixing head. Background Technology

[0002] In the resin mixing industry, traditional mixing heads commonly employ static mixing or collision-type dynamic mixing technologies, but both have significant limitations. Static mixing, due to its short mixing time and insufficient shear force, is ill-suited for handling high-viscosity raw materials, easily leading to rapid solidification of the material within the mixing chamber, forming lumps or blockages. Furthermore, static mixing requires longer piping, which not only affects mixing uniformity but also significantly increases the difficulty of system cleaning. While collision-type dynamic mixing can achieve dynamic mixing, its principle is primarily applicable to simple 1:1 ratio mixing, making it difficult to meet the precise ratio control requirements of complex formulations.

[0003] In contrast, mixing technology that utilizes high-speed rotating blades to generate vortex and turbulence effects significantly improves mixing efficiency. Its powerful shear force and thorough mixing capacity effectively suppress material solidification, reduce the risk of clogging, and lower the frequency and difficulty of cleaning. Even when faced with varying proportions and viscosities of different raw materials, this technology achieves efficient and uniform mixing. Therefore, high-speed rotating blade mixing technology overcomes the technical bottlenecks of traditional mixing methods in terms of proportion accuracy, cleaning efficiency, and sealing, providing a superior solution for achieving high-quality mixing of complex components. However, in the current market, dynamic mixing equipment often features a direct connection between the stirring shaft and the motor. This structure requires a seal on the shaft, cannot withstand high pressure, necessitates frequent seal replacement, and is not convenient to use.

[0004] Therefore, it is necessary to propose a magnetically levitated high-pressure resin mixing head to solve the problems existing in the prior art. Utility Model Content

[0024] Furthermore, the power unit 1 includes a drive member 101 and a transmission sleeve 102. The drive member 101 is fixedly disposed on the end face of the power unit fixing plate 501 away from the bottom plate 502. The power output shaft of the drive member 101 extends through the power unit fixing plate 501 and above the bottom plate 502. The transmission sleeve 102 is connected to the power output shaft of the drive member 101. The end of the transmission sleeve 102 away from the drive member 101 is connected to the active drive body 201.

[0025] Furthermore, the anti-backflow mixing unit 3 includes a mixing chamber plate 304, which is fixedly disposed on the top surface of the base plate 502 at one end away from the power unit fixing plate 501, and the sealing isolation sleeve 202 is disposed on the end face of the mixing chamber plate 304 near the power unit fixing plate 501. A mixing chamber 301 is provided on the mixing chamber plate 304. A connector 302 communicating with the mixing chamber 301 is provided on the top and front and rear side walls of the mixing chamber plate 304 respectively. A one-way valve 303 is provided in the connector 302.

[0026] Furthermore, it also includes a dynamic stirring unit 4, which includes a connecting shaft 401, stirring blades 402, a stirring jacket 403, and a quick-release assembly. The stirring blades 402 are rotatably disposed within the stirring jacket 403, and the connecting shaft 401 is rotatably disposed within the mixing chamber 301. One end of the connecting shaft 401 is connected to the passive drive body 204, and the other end of the connecting shaft 401 is connected to the stirring blades 402. The stirring jacket 403 is detachably connected to the quick-release assembly, which is disposed on the end face of the mixing chamber plate 304 away from the power unit fixing plate 501.

[0027] Furthermore, the quick-release assembly includes a connecting plate 406 and a connecting bolt 408. The connecting plate 406 includes an annular plate 4061 and a sleeve 4062 fixedly connected to the annular plate 4061. The annular plate 4061 has symmetrically opened mounting holes 4063 and arc-shaped grooves 4064 on its end face. The arc-shaped grooves 4064 communicate with the mounting holes 4063, and the width of the arc-shaped grooves 4064 is smaller than the diameter of the mounting holes 4063. A connecting bolt 408 can be detachably installed on the end face of the mixing chamber plate 304 away from the power unit fixing plate 501 at the position corresponding to the mounting hole 4063.

[0028] Furthermore, a first sealing ring 407 is provided between the annular mating surfaces of the mixing chamber plate 304 and the annular plate 4061.

[0029] Furthermore, a second sealing ring 205 is provided between the annular mating surfaces of the mixing chamber plate 304 and the sealing isolation sleeve 202.

[0030] Furthermore, an inverted U-shaped protective cover 504 is provided on the top surface of the base plate 502.

[0031] The working principle of the above technical solution: A magnetically levitated high-pressure resin mixing head includes a power unit 1, which can be either an electric motor or a hydraulic motor. A keyway is provided on the power output shaft of the power unit 1. The left end of the transmission sleeve 102 is fitted onto the power output shaft of the power unit 1. A keyway is also provided on the inner wall of the left end of the transmission sleeve 102. A flat key is provided in the keyway of the power unit and the transmission sleeve. After the power unit 1 is started, the rotation of the power output shaft can drive the transmission sleeve 102 to rotate. The transmission sleeve 102 and the active drive body 201 can also be connected by a key for transmission.

[0032] The power from power unit 1 is transmitted to the active drive body 201 via transmission sleeve 102. The active drive body 201 and the passive drive body 204 are magnetically coupled. At the relative positions of the active drive body 201 and the passive drive body 204, magnetic coupling elements (such as...) are arranged opposite each other on the inner circumferential surface of the active drive body 201 and the outer circumferential surface of the passive drive body 204. Figure 7(As shown in the black bar in the middle), the rotation of the active drive body 201 drives the rotation of the passive drive body 204 through the magnetic coupling component, which can be a magnet.

[0033] The active drive unit 201, the sealing isolation sleeve 202, and the passive drive unit 204 are sequentially fitted from the outside to the inside. The sealing isolation sleeve 202 is detachably mounted on the mixing chamber plate 304. The sealing isolation sleeve 202 is a cylindrical shape with one end open. The end away from the mixing chamber plate 304 is sealed. A flange is provided at the open end. The flange is connected to the mixing chamber plate 304 with screws. The sealing isolation sleeve 202 is coaxially mounted with the mixing chamber 301. The sealing isolation sleeve 202 is located on the end face of the mixing chamber plate 304 near the power unit fixing plate 501. A second sealing ring 205 is provided between the mating surfaces of the flange and the mixing chamber plate 304. An annular sealing groove can be opened on the flange. The second sealing ring 205 is placed in the sealing groove to prevent the raw materials mixed in the mixing chamber 301 from overflowing.

[0034] The sealing isolation sleeve 202 can be made of stainless steel. Stainless steel has high strength and can support the passive drive body 204. Stainless steel will not shield the magnetic interaction between the magnetic coupling components between the active drive body 201 and the passive drive body 204, so that torque can be smoothly transmitted between the active drive body 201 and the passive drive body 204.

[0035] The power unit 1 and the anti-backflow mixing unit 3 are fixedly mounted on the base 5. The base 5 includes a power unit fixing plate 501 and a base plate 502. The power unit fixing plate 501 is fixed to one end of the top surface of the base plate 502. The power unit fixing plate 501 is perpendicular to the base plate 502. The base plate 502 can be horizontally mounted. The power unit fixing plate 501 is parallel to the mixing chamber plate 304. The power unit fixing plate 501 is fixed to one end of the top surface of the base plate 502. The mixing chamber plate 304 is fixed to one end of the top surface of the base plate 502 away from the power unit fixing plate 501.

[0036] The mixing chamber plate 304 has connectors 302 on its top and front and rear side walls, which communicate with the mixing chamber 301. One-way valves 303 are installed inside the connectors 302. The connectors 302 on the front and rear sides can be used to connect ball valves. Raw materials from the front and rear sides enter the mixing chamber 301 through the ball valves. The connector 302 on the top can be used to add color paste or small proportions of raw materials (such as...). Figure 10 As shown), a one-way valve 303 is installed in the connector 302, so that the raw materials can only flow in the direction of entering the mixing chamber 301 to prevent the backflow of the mixed composite material. A metering pump is installed between the raw material tank and the ball valve to accurately adjust the proportion of the raw materials.

[0037] After use of the mixing head, cleaning fluid can be injected into the mixing chamber 301 through the ball valve to clean the mixing chamber 301 and the mixing jacket 403, preventing the mixed raw materials from clogging the mixing chamber 301 and the mixing jacket 403 after drying.

[0038] The left end of the connecting shaft 401 is connected to the passive drive body 204, and the right end of the connecting shaft 401 is connected to the stirring blade 402. Both of these connections can be made using a key connection. The passive drive body 204 transmits torque to the stirring blade 402 through the connecting shaft 401. The stirring blade 402 spirally propels the two different raw materials in the mixing chamber 301 into the stirring jacket 403. During the spiral propulsion process, the two raw materials are fully mixed and then discharged from the outlet.

[0039] The stirring blade 402 may include a stirring shaft and a spiral blade disposed on the circumferential surface of the stirring shaft. Both the stirring shaft and the spiral blade are existing technologies and will not be described in detail here.

[0040] The mixing jacket 403 is detachably connected to the mixing chamber plate 304 via a quick-release assembly. The quick-release assembly includes a connecting plate 406 and connecting bolts 408. The connecting bolts 408 are threaded onto the mixing chamber plate 304. The connecting plate 406 includes an annular plate 4061 and a sleeve 4062 fixedly connected to the annular plate 4061. The annular plate 4061 has symmetrically formed mounting holes 4063 and arc-shaped grooves 4064 on its end face. The arc-shaped grooves 4064 communicate with the mounting holes 4063. The width of the arc-shaped grooves 4064 is smaller than the diameter of the mounting holes 4063. The diameter of the nut of the connecting bolts 408 is larger than the width of the arc-shaped grooves 4064 but smaller than the diameter of the mounting holes 4063. Figure 6 As shown, in position 1, tightening the two connecting bolts 408 will fix the dynamic stirring unit 4 onto the mixing chamber plate 304. When it is necessary to disassemble the dynamic stirring unit 4, loosen the connecting bolts 408 and rotate the annular plate 4061 counterclockwise so that the mounting hole 4063 is rotated to the position of the connecting bolt 408. Then, pull the mixing jacket 403 outward along the axis of the mixing jacket 403 to easily disassemble it. During installation, the operation is reversed. Align the mounting hole 4063 with the connecting bolt 408 and push the mixing jacket 403 toward the mixing chamber plate 304 until it fits against the mixing chamber plate 304. Then, rotate the annular plate 4061 clockwise until the end of the arc groove 4064 away from the mounting hole 4063 contacts the connecting bolt 408. Finally, tighten the connecting bolt 408 to install the mixing jacket 403 into place.

[0041] The quick-release assembly allows for easy removal of the stirring blade 402 and cleaning of the mixing chamber 301. The stirring blade 402 can be fixedly connected to the connecting shaft 401. The connecting shaft 401 is connected to the passive drive body 204 via a keyway. A keyway is formed on the outer circumferential surface of the connecting shaft 401 and the inner circumferential surface of the passive drive body 204. One of the keyways extends to the end face. For example, the keyway on the passive drive body 204 extends to the end face of the passive drive body 204 away from the power unit 1. The keyway is installed in the keyway of the connecting shaft 401. Pulling the connecting shaft 401 outwards separates the connecting shaft 401 from the passive drive body 204. Aligning the keyway with the keyway and pushing the connecting shaft 401 into the hole of the passive drive body 204 completes the transmission connection between the connecting shaft 401 and the passive drive body 204.

[0042] The mixing jacket 403 is detachably connected to the connecting plate 406 via the connecting nut 405. The tail of the mixing jacket 403 is provided with an annular wing 4031. The diameter of the wing 4031 is larger than the outer diameter of the mixing jacket 403. The wing 4031 is pressed tightly to the sleeve 4062 by the pressure ring 4051 of the connecting nut 405. A sealing ring 404 is provided between the mixing jacket 403 and the connecting plate 406.

[0043] An inverted U-shaped protective cover 504 is provided on the top surface of the base plate 502. As the transmission sleeve 102 rotates, the protective cover 504 can protect the staff from injury caused by the transmission sleeve 102. The power unit fixing plate 501 and the base plate 502 are fixed together by a reinforcing plate 503. The side plate of the protective cover 504 is slotted at the position opposite to the reinforcing plate 503 to prevent interference during installation.

[0044] The beneficial effects of the above technical solution are as follows: The magnetic levitation high-pressure resin mixing head of this utility model adopts magnetic coupling transmission between the active driving body and the passive driving body. During operation, the position between the sealing isolation sleeve and the anti-backflow mixing unit remains unchanged. Compared with the traditional seal between the rotating shaft and the housing, the sealing ring has a longer service life, a simpler structure, and higher reliability.
