Description

Technical Field

[0001] This utility model belongs to the field of high-pressure homogenization technology, and in particular relates to a flow guiding mechanism for a high-pressure homogenizer used in dye synthesis. Background Technology

[0002] In the field of dye synthesis, high-pressure homogenizers are essential equipment for achieving ultrafine dispersion and homogenization of dye particles. They utilize ultra-high pressure to force the dye slurry through extremely precise homogenizing valve gaps at high speed. The intense shear force, cavitation effect, and violent impact generated in this process effectively break down dye particle aggregates, achieving fine dispersion at the nanometer or submicron level. Ultimately, this significantly improves the dye's coloring strength, stability, and batch consistency, ensuring the production of high-quality dye products.

[0003] The flow guiding mechanism of a high-pressure homogenizer is typically located in the inlet area of ​​the homogenizing valve, and its function is to optimize the pre-distribution and directional guidance of the material. The flow guiding structure guides the turbulent material pumped by the high-pressure pump in an orderly manner into the narrow shear zone of the homogenizing valve. Due to unreasonable design of the flow guiding structure in related technologies or increased surface roughness after long-term wear, high-viscosity dye slurries, fibrous impurities, or undispersed particles can easily accumulate and adhere, causing partial or complete blockage problems. Utility Model Content

[0004] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A flow guiding mechanism for a high-pressure homogenizer used in dye synthesis includes a spiral flow guiding groove, a spiral lifting mechanism, a cleaning mechanism, a support structure, a flow guiding sleeve, and an installation sleeve.

[0007] The spiral guide channel has a hollow structure at its axial position. The spiral lifting mechanism is located at the axial position of the spiral guide channel. The guide sleeve is located below the spiral guide channel. The discharge position at the bottom of the spiral guide channel is located inside the guide sleeve.

[0008] The output end of the spiral lifting mechanism is detachably connected to the cleaning mechanism, which is used to clean the inside of the spiral guide channel.

[0009] The support structure includes multiple support frames, which are evenly arranged circumferentially on the outside of the spiral guide groove. The support frames are detachably connected to the spiral guide groove and the guide sleeve. The bottom of the guide sleeve is connected to the mounting sleeve, and the mounting sleeve is detachably connected to the feed inlet of the high-pressure homogenizer.

[0010] Furthermore, the spiral lifting mechanism includes a fixed sleeve, a lifting device, a push block, and two fixed rods. The fixed sleeve is located at the axial position of the spiral guide groove. The fixed end of the lifting device is located at the top of the fixed sleeve. The output end of the lifting device and the push block are both located inside the fixed sleeve. The output end of the lifting device is rotatably connected to the push block through a bearing. The push block is detachably connected to the cleaning mechanism. The fixed sleeve has a spiral stroke hole. The connecting rod of the cleaning mechanism is located inside the spiral stroke hole. The two fixed rods are symmetrically arranged at the bottom of the fixed sleeve. One end of the fixed rod is fixedly connected to the fixed sleeve, and the other end of the fixed rod is fixedly connected to the inner wall of the guide sleeve.

[0011] Furthermore, the support structure also includes a fixing ring, and the top of each support frame is connected to the fixing ring.

[0012] Furthermore, the lifting device is an electric push rod.

[0013] Furthermore, the cleaning mechanism includes a connecting rod, a connecting frame, and a cleaning brush. The connecting rod is detachably connected to the push block. The end of the connecting frame is fixedly connected to the connecting rod. The connecting frame has an L-shaped structure. The side of the connecting frame is located on the outside of the spiral guide groove, and the crossbar of the connecting frame is located on the inside of the spiral guide groove. The cleaning brush is located on the crossbar of the connecting frame.

[0014] Furthermore, the top of the spiral guide channel is provided with a guide slope.

[0015] Furthermore, the number of support frames is four, and the bottom of the support frame is provided with a bent edge, which is used to limit the outer wall of the flared position of the guide sleeve.

[0016] Furthermore, the outer wall of the mounting sleeve is provided with a threaded structure.

[0017] Compared with the prior art, the flow guiding mechanism for a high-pressure homogenizer for dye synthesis described in this utility model has the following advantages:

[0018] 1. By cooperating with the connecting rod of the cleaning mechanism through the spiral stroke hole of the fixed sleeve, the cleaning mechanism achieves a compound motion of axial lifting and circumferential rotation within the spiral guide channel, ensuring that the cleaning component always conforms to the curved surface of the spiral channel; the lifting device drives the push block to transmit torque through the bearing, which not only avoids the mechanism from jamming during the cleaning action, but also can withstand radial off-center loads under high pressure conditions; and the rigid connection between the fixed rod and the guide sleeve provides a stable support foundation against fluid impact for the entire lifting system, significantly improving motion accuracy and durability.

[0019] 2. The L-shaped connecting frame of the cleaning mechanism runs through the space inside and outside the spiral guide channel, allowing the cleaning brush to cover the inner wall of the channel simultaneously while maintaining transmission. The arrangement of the brush inside the connecting frame crossbar enables continuous enveloping scraping of the spiral curved surface, which is particularly good at removing the hardened residue of high-viscosity dyes at the bends of the diameter change. The quick-release interface between the connecting rod and the lifting mechanism push block can be disassembled according to the working conditions, which can switch between hard scrapers or flexible brush heads for different pollution characteristics, and greatly reduce the complexity of maintenance.

[0032] A flow guiding mechanism for a high-pressure homogenizer used in dye synthesis, such as Figure 1 As shown, the device includes a spiral guide channel 200, a spiral lifting mechanism, a cleaning mechanism 600, a support structure 100, a guide sleeve 400, and an installation sleeve 500. The spiral guide channel 200 has a hollow structure at its axial position. The spiral lifting mechanism is located at the axial position of the spiral guide channel 200. The guide sleeve 400 is located below the spiral guide channel 200, and the discharge position at the bottom of the spiral guide channel 200 is located inside the guide sleeve 400. The top of the spiral guide channel 200 has a guide slope 210. The outer wall of the installation sleeve 500 has a threaded structure.

[0033] The L-shaped connecting frame of the cleaning mechanism 600 runs through the space inside and outside the spiral guide channel 200, allowing the cleaning brush to simultaneously cover the inner wall of the channel while maintaining transmission. The arrangement of the brush inside the connecting frame crossbar enables continuous enveloping scraping of the spiral curved surface, which is particularly good at removing the hardened residue of high-viscosity dyes at the bends where the diameter changes. The quick-release interface between the connecting rod and the lifting mechanism push block can be disassembled according to the working conditions, allowing for switching between hard scrapers or flexible brush heads for different pollution characteristics, and greatly reducing maintenance complexity.

[0034] The push block of the spiral lifting mechanism is detachably connected to the cleaning mechanism 600. The cleaning mechanism 600 is used to clean the inside of the spiral guide channel 200. The cleaning mechanism 600 includes a connecting rod, a connecting frame, and a cleaning brush. The connecting rod is detachably connected to the push block. The end of the connecting frame is fixed to the connecting rod. The connecting frame has an L-shaped structure. The side of the connecting frame is located on the outside of the spiral guide channel 200, and the crossbar of the connecting frame is located on the inside of the spiral guide channel 200. The cleaning brush is located on the crossbar of the connecting frame.

[0035] The support structure 100 includes multiple support frames, which are evenly arranged circumferentially on the outer side of the spiral guide channel 200. The support frames are detachably connected to the spiral guide channel 200 and the guide sleeve 400. The bottom of the guide sleeve 400 is connected to the mounting sleeve 500, which is detachably connected to the inlet of the high-pressure homogenizer. The support structure 100 also includes a fixing ring 110, with the top of each support frame connected to the fixing ring 110. There are four support frames, and the bottom of each support frame has a bent edge, which is used to limit the outer wall of the flared section of the guide sleeve 400.

[0036] The spiral lifting mechanism includes a fixed sleeve 320, a lifting device 310, a push block, and two fixed rods 330. The fixed sleeve 320 is located at the axial position of the spiral guide groove 200. The fixed end of the lifting device 310 is located at the top of the fixed sleeve 320. The output end of the lifting device 310 and the push block are both located inside the fixed sleeve 320. The output end of the lifting device 310 is rotatably connected to the push block via a bearing. The push block is detachably connected to the cleaning mechanism 600. The fixed sleeve 320 has a spiral stroke hole. The connecting rod of the cleaning mechanism 600 is located inside the spiral stroke hole. The two fixed rods 330 are symmetrically arranged at the bottom of the fixed sleeve 320. One end of the fixed rod 330 is fixedly connected to the fixed sleeve 320, and the other end of the fixed rod 330 is fixedly connected to the inner wall of the guide sleeve 400. The lifting device 310 is an electric push rod. By cooperating with the connecting rod of the cleaning mechanism 600 through the spiral stroke hole of the fixed sleeve 320, the cleaning mechanism 600 achieves a compound motion of axial lifting and circumferential rotation within the spiral guide channel 200, ensuring that the cleaning component always conforms to the curved surface of the spiral channel. The lifting device 310 drives the push block to transmit torque through the bearing, which not only prevents the mechanism from jamming during the cleaning action, but also withstands radial off-center loads under high pressure conditions. The rigid connection between the fixed rod 330 and the guide sleeve 400 provides a stable support foundation against fluid impact for the entire lifting system, significantly improving motion accuracy and durability.

[0037] How this example works

[0038] Step 1: The material is injected into the top of the spiral guide channel by a high-pressure pump. It is accelerated in layers by centrifugal force and guidance along the preset spiral surface. The flow pattern is smoothly transitioned through the top guide slope, eliminating turbulence. The optimized spiral trajectory forces the dye slurry to turn and compress evenly, forming a high-speed laminar flow that accurately flows into the inner cavity of the guide sleeve.

[0039] Step 2: When the system detects abnormal flow channel pressure difference or initiates maintenance according to the preset cycle, the electric push rod of the spiral lifting mechanism drives the push block to advance axially along the fixed sleeve, forcing the connecting rod to generate forced rotational displacement along the spiral stroke hole; the resulting compound motion transforms the linear thrust into the spatial spiral motion trajectory of the cleaning mechanism, ensuring that the cleaning component always maintains dynamic fit with the complex curvature of the spiral channel.

[0040] Step 3: The L-shaped connecting frame of the cleaning mechanism spirals out synchronously with the lifting mechanism. Its crossbar position drives the cleaning brush to completely sweep the inner curved surface of the spiral guide channel in an envelope motion. During the rotation and descent, the brush simultaneously covers the inner working surface of the channel and the dead corners of the outer structure, thoroughly removing the hardened dye deposits, especially achieving directional removal of fiber impurities in the transition zone of the variable diameter.

[0041] Step 4: After cleaning, the lifting mechanism reverses and lifts, causing the cleaning brush to retract along the original spiral path to the top of the guide channel for secondary cleaning. After completion, the cleaning brush descends to the initial retracted position and moves out at the outlet of the spiral guide channel. The cleaning brush is removed from the working area of ​​the flow channel to avoid interfering with the flow of the medium. At the same time, the rigid frame formed by the fixing ring and the support structure maintains the precise alignment of the guide sleeve and the installation sleeve. The bottom threaded interface ensures a leak-free re-sealing with the homogenizer body. The system immediately enters standby or restarts production.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
