Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultra-fine microfiber powder production, in particular to an ultra-fine microfiber powder anti-blocking filtering device. Background Art
[0002] Ultrafine microfiber powder filtration is a technology for filtering ultrafine microfiber powders, aiming to remove impurities, particles or other unwanted components in the powder to achieve the purpose of purification, cleansing or separation.
[0003] After searching, the patent with patent announcement number CN210230570U discloses a wood fiber powder anti-blocking filtering device. Although the device starts the driving motor when in use, so that the connecting roller drives the stirring roller to rotate, so that the powder passes through the filter net and falls onto the activated carbon block, the device cannot process the retained large particles of impurities when in use. The large particles of impurities will gradually accumulate on the filter net and block the filter net, thereby affecting the subsequent filtration efficiency. Utility Model Content
[0004] In view of the deficiencies of the prior art, the utility model provides an ultra-fine microfiber powder anti-blocking filtering device, which solves the problems raised in the background technology.
[0005] The utility model solves the above-mentioned technical problems as follows:
[0006] An anti-blocking filtering device for ultra-fine microfiber powder comprises a feeding device, one end of which is provided with a feeding device;
[0007] The feeding device is provided with a hopper, the bottom end of the hopper is connected with a connector, and the hopper of the feeding device is connected with the feeding device through the connector;
[0008] The feeding device is provided with a connecting pipe, an auger is installed inside the connecting pipe, a screen pipe is provided in the middle of the feeding device, a discharge port is provided at one end of the connecting pipe away from the feeding device, and a screening device is installed on the feeding device outside the screen pipe;
[0009] The screening device is provided with a discharge pipe and an air inlet pipe, and a cavity is provided inside the screening device, and the discharge pipe and the air inlet pipe are connected through the cavity.
[0010] On the basis of the above technical solution, the present invention can also be improved as follows.
[0011] Furthermore, the hopper and the connector are connected and fixed via a flange.
[0012] The beneficial effects of adopting the above further scheme are:
[0013] Flange connection is a commonly used method for connecting pipelines and equipment. It uses bolts to tightly press two flanges together to form a high-strength connection structure. When making a flange connection, a sealing gasket or sealing rubber ring is usually placed between the two flanges to further improve the connection's tightness. This connection method can withstand large pressures and tensile forces, ensuring a stable connection between the hopper and the connector and preventing loosening or detachment during transportation or operation.
[0014] Furthermore, the feeding device is rotationally inserted into the connector of the loading device.
[0015] The beneficial effect of adopting the above further solution is:
[0016] The design of rotational insertion allows the feeding device to have a certain degree of rotational freedom within the connector of the loading device. This design makes it convenient for the feeding device to rotate within the loading device, and thus facilitates the feeding operation of the feeding device.
[0017] Furthermore, rotational seals are installed at both ends of the screening device, and the screening device is rotationally installed on the feeding device through the rotational seals.
[0018] The beneficial effect of adopting the above further solution is:
[0019] The design of rotational seals ensures good sealing between the screening device and the feeding device during rotation. This is particularly important for handling easily airborne materials such as ultra-fine fiber powder because the tightness directly affects the cleanliness of the working environment and the quality of the product. Through rotational seals, it is possible to effectively prevent raw materials from leaking out through the gap between the screening device and the feeding device during the screening process.
[0020] Furthermore, the discharge pipe is located on the upper surface of the screening device, and the intake pipe is located on the lower surface of the screening device.
[0021] The beneficial effect of adopting the above further solution is:
[0022] The discharge pipe is designed on the upper surface of the screening device, which can ensure that the screened materials can be discharged smoothly and quickly, avoiding accumulation inside the screening device. This design helps to reduce the residence time of the materials during the screening process, thereby improving the efficiency and effectiveness of screening. The intake pipe is located on the lower surface of the screening device, enabling the high-pressure air flow to act directly on the materials below the screen mesh, forming an upward air flow force. This air flow force helps to disperse the materials on the screen mesh and accelerate their movement, further improving the uniformity and efficiency of screening. During the screening process, due to the different particle sizes and shapes of the materials, the screen mesh is prone to clogging. Designing the intake pipe on the lower surface of the screening device can effectively reduce the risk of screen mesh clogging through the purging action of the high-pressure air flow. When the screen mesh becomes clogged, the high-pressure air flow can quickly disperse the clogging materials and restore the smoothness of the screen mesh.
[0023] Further, the intake pipe is connected to a high-pressure gas source, and the raw materials in the sieve tube are screened by the high-pressure air flow. The screened raw materials are discharged through the discharge pipe, and the discharge pipe is connected to a material collection device.
[0024] The beneficial effects of adopting the above further solution are:
[0025] Using high-pressure air flow for screening can, compared with traditional mechanical screening methods, more effectively disperse and separate the particles in the raw materials. The impact force and penetration force of the high-pressure air flow can act on all levels of the raw materials, making it easier for fine particles to pass through the screen mesh, thereby improving the screening efficiency. The high-pressure air flow not only plays a screening role during the screening process but also can effectively prevent the screen mesh from clogging. When the air flow passes through the screen mesh, it can carry away the fine particles and impurities attached to the screen mesh, maintaining the smoothness of the screen mesh.
[0026] Further, the feeding device is filled with raw materials, and the raw materials in the feeding device are introduced into the feeding device through a connector. The raw materials in the feeding device are screened through a sieve tube, and the large particle impurities intercepted in the feeding device are discharged from the discharge port.
[0027] The beneficial effects of adopting the above further solution are:
[0028] The entire raw material processing flow starts from the feeding device, is smoothly introduced into the feeding device through the connector, then screened through the sieve tube, and finally large particle impurities are discharged from the discharge port. This process design is reasonable and the steps are clear, ensuring that the raw materials can smoothly and efficiently pass through each processing link. The raw materials in the feeding device are screened through the sieve tube, which can effectively separate large particle impurities from fine particles. The large particle impurities intercepted during the screening process are directly discharged through the discharge port without additional processing steps. This design simplifies the impurity processing flow, improves work efficiency, and reduces the need for manual intervention. By screening and discharging large particle impurities through the sieve tube, it can effectively protect the subsequent processing equipment from being damaged by large particle impurities. If these impurities enter the subsequent equipment, they may cause equipment blockage, wear or damage, thus affecting the normal operation of the entire production line.
[0029] The utility model provides an anti-blocking filtration device for ultra-fine fiber powder. It has the following
[0030] Beneficial effects:
[0031] The high-pressure air flow inside the screening device can effectively screen the ultra-fine fiber powder in the sieve tube. The high-pressure air flow can penetrate the powder in the sieve tube, helping to separate the powder through the sieve mesh, thereby improving the screening efficiency. This air flow screening method is more effective than traditional mechanical vibration screening, especially when dealing with ultra-fine fiber powder.
[0032] Since the sieve tube is equipped with high-pressure air flow, it can effectively avoid the accumulation or blockage of ultra-fine powder on the surface of the sieve mesh or in the pipeline. The high-pressure air flow continuously blows the sieve mesh, reducing the deposition of powder and maintaining the smoothness of screening. This design significantly reduces the operating failures of the equipment due to powder accumulation, improving the reliability and durability of the equipment.
[0033] The sieve tube in the feeding device can intercept large particle impurities, and these intercepted impurities will be automatically discharged through the discharge port. This mechanism ensures that the materials inside the equipment always maintain a high purity and reduces the need for manual cleaning and maintenance of the equipment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0042] Please refer to Figures 1 to 3 As shown, the embodiments provided by the present utility model are as follows:
[0043] Embodiment 1
[0044] A superfine fiber powder anti-blocking filtering device includes a feeding device 2. One end of the feeding device 2 is installed with a loading device 1. The loading device 1 is provided with a hopper 101. The bottom end of the hopper 101 is connected with a connector 103. The hopper 101 of the loading device 1 is communicated with the feeding device 2 through the connector 103. The feeding device 2 is rotationally inserted into the connector 103 of the loading device 1. The design of rotational insertion gives the feeding device 2 a certain degree of rotational freedom within the connector 103. This design enables the feeding device 2 to rotate conveniently within the connector 103, thus facilitating the feeding operation of the feeding device 2. The hopper 101 and the connector 103 are connected and fixed through a flange 102. The flange 102 connection, as a common connection method between pipes and equipment, tightly compresses the two flanges 102 with bolts to build a high-strength connection structure. During the connection of the flanges 102, a sealing gasket or a sealing rubber ring is usually placed between the two flanges 102 to further enhance the sealing performance of the connection. This connection method has the ability to withstand large pressures and tensile forces, and can effectively ensure the stable connection between the hopper 101 and the connector 103, avoiding loosening or falling off during transportation or operation.
[0045] Embodiment 2
[0046] In order to discharge the large particles of impurities trapped in the feeding device 2, for example, Figures 1 to 3 As shown, the present invention also includes: the feeding device 2 is provided with a connecting pipe 203, the inside of the connecting pipe 203 is welded with an auger 201, and the auger 201 is hollow, the middle part of the feeding device 2 is provided with a screen tube 202, and the end of the connecting pipe 203 away from the feeding device 1 is provided with a discharge port 204, the feeding device 1 is filled with raw materials, and the raw materials in the feeding device 1 are introduced into the feeding device 2 through the connector 103, the raw materials in the feeding device 2 are screened through the screen tube 202, and the large particle impurities trapped in the feeding device 2 are discharged from the discharge port 204, and the entire raw material processing process starts from the feeding device 1, and is smoothly introduced into the feeding device 2 through the connector 103, and then screened through the screen tube 202, and finally the large particle impurities are discharged from the discharge port 204. This process is reasonably designed and the steps are clear, which ensures that the raw materials can pass through each processing link smoothly and efficiently. The raw materials in the feeding device 2 are screened through the screen tube 202, which can effectively separate large particle impurities from fine particles. The large particle impurities trapped during the screening process are directly discharged through the discharge port 204 without the need for additional processing steps. This design simplifies the impurity processing process, improves work efficiency, and reduces the need for manual intervention. By screening and discharging large particle impurities through the screen tube 202, the subsequent processing equipment can be effectively protected from damage by large particle impurities. If these impurities enter the subsequent equipment, they may cause equipment blockage, wear or damage, thereby affecting the normal operation of the entire production line. The feeding device 2 is provided with a screening device 3 outside the screen tube 202, and a rotating seal 303 is installed at both ends of the screening device 3. The screening device 3 is rotatably installed on the feeding device 2 through the rotating seal 303. The design of the rotating seal 303 ensures good sealing performance between the screening device 3 and the feeding device 2 during the rotation process. This is particularly critical for processing ultra-fine microfiber powder and other easy-to-fly materials, because the quality of the sealing performance is directly related to the cleanliness of the working environment and the quality of the product. Through the rotating seal 303, the raw material can be effectively prevented from leaking from the gap between the screening device 3 and the feeding device 2 during the screening process.
[0047] Embodiment 3
[0048] In order to screen the raw materials in the screen tube 202 by the screening device 3, for example, Figures 1 to 3As shown in the figure, the present invention further includes: a screening device 3 is provided with a discharge pipe 302 and an air inlet pipe 304. The discharge pipe 302 is located on the upper surface of the screening device 3, and the air inlet pipe 304 is located on the lower surface of the screening device 3. Setting the discharge pipe 302 on the upper surface of the screening device 3 can ensure that the screened material is discharged smoothly and quickly, avoiding accumulation inside the screening device 3. Such a design helps to reduce the residence time of the material during the screening process, thereby improving the screening efficiency and effect. The air inlet pipe 304 is located on the lower surface of the screening device 3, so that the high-pressure air flow can directly act on the material below the screen, forming an upward air flow force. This air flow force helps to blow and accelerate the movement of the material on the screen, thereby further improving the screening uniformity and efficiency. During the screening process, due to the different particle sizes and shapes of the materials, the screen is very likely to be blocked. Setting the air inlet pipe 304 on the lower surface of the screening device 3 can effectively reduce the risk of screen blockage by means of the purging action of the high-pressure air flow. When the screen is blocked, the high-pressure air flow can quickly blow away the blockage and restore the smoothness of the screen. And there is a cavity 301 inside the screening device 3. The discharge pipe 302 and the air inlet pipe 304 are connected through the cavity 301. The air inlet pipe 304 is connected to a high-pressure air source. The raw materials in the sieve tube 202 are screened by the high-pressure air flow. The screened raw materials are discharged through the discharge pipe 302. The discharge pipe 302 is connected to a material collection device. Using the high-pressure air flow for screening can disperse and separate the particles in the raw materials more efficiently compared with the traditional mechanical screening method. The impact force and penetration force of the high-pressure air flow can act on all levels of the raw materials, making it easier for the fine particles to pass through the screen, thereby improving the screening efficiency. The high-pressure air flow not only plays a screening role during the screening process, but also can effectively prevent the screen from being blocked. When the air flow passes through the screen, it can take away the fine particles and impurities attached to the screen and keep the screen smooth.
[0049] Working principle:
[0050] The feeding device 2 is connected to the feeding device 1 through a connector 103, and the raw materials are introduced into the feeding device 2 from the hopper 101 of the feeding device 1 through the connector 103. There is a connecting pipe 203 inside the feeding device 2. A auger 201 is installed in the connecting pipe 203. The rotational movement of the auger 201 pushes the raw materials to move forward in the connecting pipe 203.
[0051] During the process of the raw materials moving forward in the feeding device 2, they are preliminarily screened through a sieve tube 202. The aperture of the sieve tube 202 is designed to intercept large particle impurities, and these impurities cannot pass through the aperture of the sieve tube 202, so they accumulate inside the sieve tube 202. As the screening process progresses, the large particle impurities accumulated in the sieve tube 202 gradually increase. When it reaches a certain level, these impurities are discharged outside the device through the discharge port 204 to prevent blockage.
[0052] In order to further improve the screening accuracy, a screening device 3 is installed on the feeding device 2. Inside the screening device 3, there is a cavity 301, which is communicated with the cavity 301 through a discharge pipe 302 and an intake pipe 304. The intake pipe 304 is connected to a high-pressure gas source and is used to provide high-pressure air flow. When the high-pressure air flow enters the cavity 301 of the screening device 3 through the intake pipe 304, the air flow further finely screens the raw materials in the sieve tube 202. The impact of the high-pressure air flow enables the fine particles in the raw materials to be separated and enter the subsequent processing process through the aperture of the sieve tube 202. The raw materials after fine screening are discharged from the screening device 3 through the discharge pipe 302 and are communicated with the material collection equipment for subsequent collection and processing.
