Description

Technical Field

[0001] This utility model relates to the screening of highly viscous and highly adhesive materials, and more particularly to a filtration device suitable for screening PTFE dispersion resin particles. Background Technology

[0002] Polytetrafluoroethylene (PTFE) dispersion resin is a core raw material for high-performance coatings, microporous membranes, and medical implant materials. Before processing, it needs to be screened to remove agglomerated particles and impurities to ensure particle size uniformity. However, traditional screens are difficult to adapt to the characteristics of PTFE resin due to structural defects: First, PTFE particles are extremely fine (micron-level), have an oleophilic and hydrophobic surface, and are prone to static electricity, causing particles to easily agglomerate and adhere to the screen holes and surface, resulting in high clogging rate and low filtration efficiency; Second, traditional flat screen plates lack disturbance and flow guidance design, making it difficult to remove accumulated particles, requiring frequent shutdowns for cleaning, resulting in decreased production efficiency and fluctuations in screening quality.

[0003] Therefore, developing a novel sieve plate device that integrates an anti-adhesion surface, a dynamic flow guiding structure, and a self-cleaning function is of great significance for improving the sieving efficiency and stability of PTFE resin. Utility Model Content

[0004] In view of the above-mentioned shortcomings of current filtration equipment, this utility model provides a filtration device suitable for screening PTFE dispersed resin particles. It can guide the particles to roll along a non-linear path to form micro-turbulence during the screening process, reduce accumulation and clogging, and reduce resin adhesion through fluid flushing force.

[0005] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0006] A filtration device suitable for screening PTFE dispersed resin particles, the filtration device includes a housing, a feed inlet on the housing, a sieve plate inside the housing, the sieve plate being connected to a vibrating component, and a collection chamber below the sieve plate; the surface of the sieve plate is provided with a plurality of longitudinally distributed undulating guide grooves, the channels of the undulating guide grooves being configured with a wave-shaped undulating structure, or the channels of the undulating guide grooves being provided with staggered protrusions.

[0007] According to one aspect of the present invention, the wave guide groove is embedded with an elastic vibrating plate.

[0008] According to one aspect of the present invention, the surface of the sieve plate is covered with an antistatic coating or a nano-ceramic film.

[0009] According to one aspect of the present invention, the sieve plate includes a coarse sieve plate, a medium sieve plate and a fine sieve plate arranged sequentially from top to bottom, and all of them are integral rigid structures.

[0010] According to one aspect of the present invention, the collecting chamber is disposed below the sieve plate, and the collecting chamber is movable.

[0011] According to one aspect of the present invention, the tail or side of the sieve plate is provided with an impurity discharge port.

[0012] According to one aspect of the present invention, the housing is provided with a transparent and visible structure around its perimeter, and one side of it is openable.

[0013] According to one aspect of the present invention, the feed inlet is located at the top of the housing and is provided with a flow regulating mechanism to ensure uniform material distribution.

[0014] According to one aspect of the present invention, the vibration component is disposed on one side of the housing.

[0015] According to one aspect of the present invention, an elastic support frame is provided below the housing.

[0016] The advantages of this invention are as follows: The PTFE resin is guided along a non-linear path by the undulating guide channels (wave-shaped or staggered protrusions) distributed on the surface of the sieve plate, creating a "micro-turbulence" state to reduce particle accumulation and adhesion. Simultaneously, the elastic vibrating plates embedded in the guide channels oscillate with the material flow or equipment vibration, dynamically disturbing the particles and peeling off adhering substances, assisting in the discharge of impurities. Their periodic oscillation also simultaneously "sweeps" the inner wall of the guide channels, achieving self-cleaning. The synergistic effect of these two components, combined with antistatic surface treatment, significantly improves the screening efficiency and anti-clogging ability of PTFE resin materials. This equipment can be widely used in the screening of highly viscous and highly adhesive materials. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, a filtration device suitable for screening PTFE dispersed resin particles includes a housing 1 with a feed inlet 2. A sieve plate 4 is located inside the housing 1 and connected to a vibrating component 7. A collection chamber 5 is located below the sieve plate 4. The surface of the sieve plate 4 has several longitudinally distributed undulating guide channels 6. The channels of the undulating guide channels 6 are configured with a wave-like undulating structure, or the channels of the undulating guide channels 6 have staggered protrusions. During operation, the undulating guide channels 6 distributed on the sieve plate 4 guide the particles to roll along a non-linear path, forming micro-turbulence, reducing accumulation and clogging, and mitigating resin adhesion through fluid scouring force.

[0025] In practical applications, the surface of sieve plate 4 is coated with an antistatic coating or a nano-ceramic film. Since PTFE particles are prone to static electricity, the antistatic coating or nano-ceramic film on the surface of sieve plate 4 effectively suppresses electrostatic adsorption.

[0026] In practical use, the system includes a coarse sieve plate 41, a medium sieve plate 42, and a fine sieve plate 43 arranged sequentially from top to bottom, all of which are integral rigid structures. During operation, it includes at least two screening layers with progressively smaller pore sizes, effectively distinguishing impurities of different particle sizes and improving material purity.

[0027] In practical use, the collection chamber 5 is located below the sieve plate 4, and the collection chamber 5 is movable. It is used to collect PTFE resin particles of suitable size that have passed the screening.

[0028] In practical use, the tail or side of the sieve plate 4 is provided with an impurity discharge port 3. Impurities that have not passed the screening are swept out of the sieve plate 4.

[0029] In practical use, the shell 1 is designed with a transparent and visible structure on all four sides, and one side can be opened. This facilitates observation of the screening results and collection of the PTFE resin particles that have passed the screening in the collection chamber 5.

[0030] In practical use, the feed inlet 2 is located at the top of the housing 1 and is equipped with a flow regulation mechanism to ensure uniform material distribution.

[0031] In actual use, the vibrating component 7 is located on one side of the housing 1. During operation, the vibrating component 7 drives the screen plate 4 to vibrate and screen materials.

[0032] In actual use, an elastic support frame 9 is provided below the housing 1 to support the vibration of the vibrating component 7.

[0033] The advantages of this invention are: the PTFE resin is guided to roll along a non-linear path by the wavy guide grooves 6 (wave-shaped or staggered protrusions) distributed on the surface of the sieve plate 4, forming a "micro-turbulence" state to reduce particle accumulation and adhesion; at the same time, combined with antistatic surface treatment, the screening efficiency and anti-clogging ability of PTFE resin materials are significantly improved.

[0034] Example 2

[0035] like Figure 1 and Figure 2 As shown, a filtration device suitable for screening PTFE dispersed resin particles includes a housing 1 with a feed inlet 2. A sieve plate 4 is located inside the housing 1 and connected to a vibrating component 7. A collection chamber 5 is located below the sieve plate 4. The surface of the sieve plate 4 has several longitudinally distributed undulating guide channels 6. The channels of the undulating guide channels 6 are configured with a wave-like undulating structure, or the channels of the undulating guide channels 6 have staggered protrusions. During operation, the undulating guide channels 6 distributed on the sieve plate 4 guide the particles to roll along a non-linear path, forming micro-turbulence, reducing accumulation and clogging, and mitigating resin adhesion through fluid scouring force.

[0036] In practical applications, the surface of sieve plate 4 is coated with an antistatic coating or a nano-ceramic film. Since PTFE particles are prone to static electricity, the antistatic coating or nano-ceramic film on the surface of sieve plate 4 effectively suppresses electrostatic adsorption.

[0037] In practical use, the system includes a coarse sieve plate 41, a medium sieve plate 42, and a fine sieve plate 43 arranged sequentially from top to bottom, all of which are integral rigid structures. During operation, it includes at least two screening layers with progressively smaller pore sizes, effectively distinguishing impurities of different particle sizes and improving material purity.

[0038] In practical use, the collection chamber 5 is located below the sieve plate 4, and the collection chamber 5 is movable. It is used to collect PTFE resin particles of suitable size that have passed the screening.

[0039] In practical use, the tail or side of the sieve plate 4 is provided with an impurity discharge port 3. Impurities that have not passed the screening are swept out of the sieve plate 4.

[0040] In practical use, the shell 1 is designed with a transparent and visible structure on all four sides, and one side can be opened. This facilitates observation of the screening results and collection of the PTFE resin particles that have passed the screening in the collection chamber 5.

[0041] In practical use, the feed inlet 2 is located at the top of the housing 1 and is equipped with a flow regulation mechanism to ensure uniform material distribution.

[0042] In actual use, the vibrating component 7 is located on one side of the housing 1. During operation, the vibrating component 7 drives the screen plate 4 to vibrate and screen materials.

[0043] In actual use, an elastic support frame 9 is provided below the housing 1 to support the vibration of the vibrating component 7.

[0044] In practical use, the undulating guide channel 6 is embedded with an elastic vibrating plate 8. During operation, the elastic vibrating plate 8 oscillates with the flow of particles or the micro-vibration of the equipment, disturbing and peeling the particles, and helping to push impurity particles out; at the same time, it periodically "sweeps" the inner wall of the guide channel by oscillation, preventing resin particles from adhering. This elastic vibrating plate 8 can achieve the micro-disturbance function without electric drive and also has a self-cleaning effect.

[0045] The filtration device in the above embodiments can also be optimized as follows:

[0046] The sieve plate 4 is provided with wave guide grooves 6 in both the transverse and longitudinal directions, which are densely and alternately arranged;

[0047] The transverse direction of sieve plate 4 is slightly inclined from the edge to the center.

[0048] The advantages of this invention are as follows: The undulating guide channels 6 (wave-shaped or staggered protrusions) distributed on the surface of the sieve plate 4 guide the PTFE resin to roll along a non-linear path, forming a "micro-turbulence" state to reduce particle accumulation and adhesion. Simultaneously, the elastic vibrating plates 8 embedded in the guide channels oscillate with the material flow or equipment vibration, dynamically disturbing the particles and peeling off adhering substances, assisting in the discharge of impurities. Their periodic oscillation also simultaneously "sweeps" the inner wall of the guide channels, achieving self-cleaning. The synergistic effect of these two mechanisms, combined with antistatic surface treatment, significantly improves the screening efficiency and anti-clogging ability of PTFE resin materials. This equipment can be widely used in the screening of highly viscous and highly adhesive materials.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
