Description

Technical Field

[0001] The utility model relates to the technical field of ultrafine fiber powder processing, and particularly relates to a conveying device for processing ultrafine fiber powder. Background Art

[0002] An ultrafine fiber powder conveying device, as the name implies, refers to a mechanical device that can transport ultrafine fiber powder from one place to another. Since ultrafine fiber powder has the characteristics of small particle size, large specific surface area, easy moisture absorption, easy caking, etc., the requirements for its conveying device are relatively high.

[0003] After retrieval, the patent with the patent publication number CN210122380U discloses a powder conveying pipe relay device. Although the device can access multiple relay devices in a single long conveying pipe during use, and the central air flow of each relay device can continuously push the powder to move, the high-pressure air inlet pipe is exposed outside during use and is easily damaged, resulting in the equipment being unable to work properly. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a conveying device for processing ultrafine fiber powder, which solves the problems put forward in the background art.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] A conveying device for processing ultrafine fiber powder includes an inner lining pipe, and an outer sleeve pipe is arranged outside the inner lining pipe;

[0007] A high-pressure air cavity is formed inside the outer sleeve pipe, a partition is arranged inside the high-pressure air cavity, and a high-pressure air inlet pipe is arranged on the high-pressure air cavity;

[0008] A flow channel is arranged inside the inner lining pipe, air holes are formed through the flow channel of the inner lining pipe, and a rubber lining plate is arranged on the inner surface of the flow channel at the position of the air holes.

[0009] On the basis of the above technical solution, the utility model can be further improved as follows.

[0010] Further, flange plates are arranged at both ends of the inner lining pipe, and fixing holes are formed through the flange plates. The inner lining pipe is locked and fixed through the flange plates, the fixing holes and bolts.

[0011] The beneficial effect of adopting the above further scheme is:

[0012] As a connecting piece, the flange is designed to make the connection between the inner lining pipe and other components (such as the outer casing pipe or the interface devices at the front and rear ends) more stable. By tightening and fixing with bolts, sufficient pre-tightening force can be generated to ensure that even under vibration or impact during transmission, the connection will not become loose or fall off, thus ensuring the stable operation of the entire conveying device.

[0013] Furthermore, the air holes are evenly distributed on the inner lining pipe, and the angle between the air holes and the horizontal plane is fifteen degrees.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The even distribution of the air holes on the inner lining pipe ensures that the high-pressure air flow can enter the flow channel evenly, thereby realizing the even blowing of the ultra-fine fiber powder. This uniformity helps to reduce the agglomeration and blockage of the material during transmission and improve the transmission efficiency. The design with the angle between the air holes and the horizontal plane being fifteen degrees enables the air flow to form a specific flow direction after entering the flow channel. This design helps to optimize the guidance of the air flow, enabling the air flow to more effectively push the material forward in the flow channel. At the same time, the appropriate angle can also reduce the direct impact of the air flow on the material and reduce the risk of material breakage.

[0016] Furthermore, the air holes and the rubber lining plate are cross-distributed, and the rubber lining plate shields and protects the air holes to prevent the material in the flow channel from flowing back into the high-pressure air cavity from the flow channel.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The shielding and protection of the air holes by the rubber lining plate is the key to preventing the material from flowing back into the high-pressure air cavity. This design can ensure that under the action of the high-pressure air flow, the material can only move forward along the flow channel and will not flow back into the high-pressure air cavity through the air holes, avoiding the accumulation and possible blockage problems of the material in the high-pressure air cavity. By preventing the material from flowing back, this design reduces the risk of equipment failure. The smooth transmission of the material in the flow channel reduces the downtime caused by blockage or backflow, improving the overall operation efficiency and reliability of the equipment.

[0019] Furthermore, the high-pressure air cavity and the flow channel are connected through the air holes.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The air holes, as the connecting channels between the high-pressure air chamber and the flow channel, ensure that the high-pressure air flow can smoothly enter the flow channel from the high-pressure air chamber. This design enables the air flow to efficiently push the materials in the flow channel forward, thus achieving the efficient transmission of ultra-fine fiber powder. Since the air holes are evenly distributed on the inner lining tube and are connected to the high-pressure air chamber through them, it can ensure that the high-pressure air flow forms a uniform distribution in the flow channel. This uniformly distributed air flow helps to reduce the agglomeration and blockage of materials during the transmission process, improving the stability and efficiency of the transmission.

[0022] Furthermore, the material is fed through the high-pressure air flow in the flow channel, and the air pressure in the high-pressure air chamber is greater than that in the flow channel, preventing the raw materials in the flow channel from flowing back into the high-pressure air chamber.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] By maintaining the air pressure in the high-pressure air chamber higher than that in the flow channel, it can ensure that the materials in the flow channel move forward under the push of the air flow and will not flow back into the high-pressure air chamber through the air holes. This design effectively prevents the reverse flow of materials during the transmission process, ensuring the continuity and stability of the transmission. The high-pressure air flow forms a stable flow state in the flow channel, which can efficiently push the materials forward. Due to the existence of the air pressure difference, the materials can pass through the flow channel more quickly, thus improving the overall transmission efficiency.

[0025] Furthermore, the partition plates are evenly distributed in the high-pressure air chamber. The high-pressure air chamber is divided into multiple independent parts by the partition plates, and each independent high-pressure air chamber is connected to a high-pressure inlet pipe.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] The even distribution of the partition plates in the high-pressure air chamber ensures that the high-pressure air flow can be evenly distributed to each independent part. This even distribution helps to reduce the vortex and turbulence phenomena of the air flow during the transmission process, making the air flow in the flow channel more stable, thereby improving the transmission efficiency. Each independent high-pressure air chamber is connected to a high-pressure inlet pipe, which means that each part can independently receive the supply of high-pressure air flow. This design enables the air flow to act on the materials in the flow channel more directly and effectively, promoting the rapid transmission of the materials. At the same time, due to the uniformity of the air flow distribution, the transmission bottleneck problem caused by insufficient local air flow is avoided, further improving the overall transmission efficiency.

[0028] The present utility model provides a conveying device for processing ultra-fine fiber powder. It has the following beneficial effects:

[0029] By setting a high-pressure gas chamber inside the outer casing and using high-pressure air flow to feed materials in the flow channel, it ensures that the ultra-fine fiber powder can be efficiently and stably transported. The design of the air pressure difference between the high-pressure gas chamber and the flow channel effectively prevents the backflow of materials, ensuring the continuity and efficiency of transportation. The high-pressure gas chamber is evenly divided into multiple independent parts by partitions, and each part is connected with a high-pressure inlet pipe. This design enables the high-pressure air flow to be evenly distributed throughout the high-pressure gas chamber, and then act on the materials in the flow channel evenly through the air holes, ensuring the uniformity and consistency of material transportation.

[0030] The design of a specific angle (such as fifteen degrees) between the air holes and the horizontal plane, and the rubber lining plate arranged on the inner surface of the flow channel together constitute an effective anti-backflow mechanism. The rubber lining plate's shielding and protection of the air holes further enhance the ability to prevent materials from flowing back from the flow channel to the high-pressure gas chamber, ensuring the safe operation of the equipment and the purity of material transportation. In view of the characteristics of ultra-fine fiber powder (such as easy to disperse and agglomerate, etc.), this conveying device effectively solves the difficult problems in the transportation process through precise air flow control and structural design, ensuring the high-quality transportation of ultra-fine fiber powder.

[0040] See also Figures 1 to 4 As shown, the embodiments provided by the utility model:

[0041] Embodiment 1

[0042] A conveying device for processing ultrafine microfiber powder includes an inner liner tube 2, an outer sleeve 1 is arranged on the outer side of the inner liner tube 2, a high-pressure air cavity 102 is opened inside the outer sleeve 1, a partition 101 is arranged inside the high-pressure air cavity 102, a high-pressure air inlet pipe 103 is arranged on the high-pressure air cavity 102, the partition 101 is evenly distributed in the high-pressure air cavity 102, the high-pressure air cavity 102 is divided into a plurality of independent parts by the partition 101, and each independent high-pressure air cavity 102 is connected to the high-pressure air inlet pipe 103, and the uniform distribution of the partition 101 in the high-pressure air cavity 102 ensures that the high-pressure airflow can be evenly distributed to each independent part. This uniform distribution helps to reduce the eddy and turbulent phenomena of the airflow during the transmission process, so that the flow of the airflow in the flow channel 205 is more stable, thereby improving the transmission efficiency. Each independent high-pressure air cavity 102 is connected to the high-pressure air inlet pipe 103, which means that each part can independently receive the supply of high-pressure airflow. This design enables the airflow to act more directly and effectively on the material in the flow channel 205, promoting the rapid transmission of the material. At the same time, due to the uniformity of airflow distribution, the transmission bottleneck problem caused by insufficient local airflow is avoided, further improving the overall transmission efficiency.

[0043] Embodiment 2

[0044] In order to ensure the smoothness of the flow channel 205 and prevent the raw material in the flow channel 205 from flowing into the high-pressure air chamber 102, for example, Figures 1 to 4As shown, the present invention also includes: a flow channel 205 is provided inside the inner liner tube 2, and the flow channel 205 is fed by a high-pressure airflow, and the air pressure in the high-pressure air cavity 102 is greater than the air pressure in the flow channel 205, so as to prevent the raw material in the flow channel 205 from being diverted into the high-pressure air cavity 102, and by maintaining the air pressure in the high-pressure air cavity 102 higher than the air pressure in the flow channel 205, it is possible to ensure that the material in the flow channel 205 moves forward under the impetus of the airflow, and does not flow back into the high-pressure air cavity 102 through the air hole 203. This design effectively prevents the backflow phenomenon of the material during the transmission process, and ensures the continuity and stability of the transmission. The high-pressure airflow forms a stable flow state in the flow channel 205, which can efficiently push the material forward. Due to the existence of the air flow pressure difference, the material can pass through the flow channel 205 more quickly, thereby improving the overall transmission efficiency. The flow channel 205 of the inner liner tube 2 is penetrated by air holes 203, and the air holes 203 are evenly distributed on the inner liner tube 2, and the angle between the air holes 203 and the horizontal plane is fifteen degrees. The uniform distribution of the air holes 203 on the inner liner tube 2 ensures that the high-pressure air flow can evenly enter the flow channel 205, and realize the uniform blowing of the ultra-fine microfiber powder. This uniformity is of great significance for reducing the agglomeration and blockage of materials during the transmission process, and helps to improve the transmission efficiency. The design of the fifteen-degree angle between the air holes 203 and the horizontal plane enables the air flow to form a specific flow direction after entering the flow channel 205. This design not only helps to optimize the guidance of the airflow, so that the airflow can more effectively push the material forward in the flow channel 205, but also appropriately reduce the direct impact of the airflow on the material and reduce the risk of material breakage. The high-pressure air cavity 102 and the flow channel 205 are connected through the air hole 203. The air hole 203 serves as a connecting channel between the high-pressure air cavity 102 and the flow channel 205, ensuring that the high-pressure airflow can smoothly enter the flow channel 205 from the high-pressure air cavity 102. This design enables the airflow to efficiently push the material in the flow channel 205 forward, realizing the efficient transmission of ultra-fine microfiber powder. Since the air holes 203 are evenly distributed on the inner liner 2 and are connected to the high-pressure air cavity 102, it can ensure that the high-pressure airflow is evenly distributed in the flow channel 205. This evenly distributed airflow helps to reduce the agglomeration and clogging of materials during the transmission process, and improves the stability and efficiency of transmission. The inner surface of the flow channel 205 is provided with a rubber lining plate 204 at the air hole 203. The air hole 203 and the rubber lining plate 204 are cross-distributed. The rubber lining plate 204 shields and protects the air hole 203 to prevent the material in the flow channel 205 from flowing back from the flow channel 205 to the high-pressure air cavity 102. The shielding and protection of the rubber lining plate 204 on the air hole 203 is very important, and it can effectively prevent the material from flowing back into the high-pressure air cavity 102. Under the action of the high-pressure airflow, the material can only move forward along the flow channel 205, and will not flow back to the high-pressure air cavity 102 through the air hole 203, thereby avoiding the accumulation of materials in the high-pressure air cavity 102 and possible clogging problems.By preventing the backflow of materials, this design reduces the risk of equipment failure, makes the transmission of materials in the flow channel 205 smoother, reduces the downtime caused by blockage or backflow, improves the overall operating efficiency and reliability of the equipment. Flange plates 202 are provided at both ends of the inner lining pipe 2, and fixing holes 201 are penetrated through the flange plates 202. The inner lining pipe 2 is locked and fixed through the flange plates 202, fixing holes 201 and bolts. As a key connecting part, the flange plate 202 is carefully designed to ensure a firm and reliable connection between the inner lining pipe 2 and other components (such as the outer sleeve pipe 1 or the interface equipment at the front and rear ends). Through the tight locking and fixing of the bolts, sufficient pre-tightening force can be generated, so as to ensure that during the transmission process, even in the face of vibrations or impacts, etc., the connection can remain tight and will not loosen or fall off, providing a solid guarantee for the stable operation of the entire conveying device.

[0045] Working principle:

[0046] High-pressure gas is injected into the high-pressure gas chamber 102 through the high-pressure air inlet pipe 103. These high-pressure gases are evenly separated into multiple independent parts by the partition plate 101, ensuring the uniformity and stability of the air flow. The gas in the high-pressure gas chamber 102 enters the flow channel 205 through the evenly distributed air holes 203. Since the air pressure in the high-pressure gas chamber 102 is greater than the air pressure in the flow channel 205, the air flow can smoothly transport the ultra-fine fiber powder from one end to the other end. At the same time, the specific included angle design (such as fifteen degrees) between the air holes 203 and the horizontal plane helps the air flow to form a stable and uniform flow state in the flow channel 205, thereby improving the transmission efficiency.

[0047] The rubber lining plates 204 provided at the positions of the air holes 203 on the inner surface of the flow channel 205 play a key protective role. These rubber lining plates 204 are cross-distributed with the air holes 203, and can effectively block and prevent the materials in the flow channel 205 from flowing back into the high-pressure gas chamber 102 through the air holes 203. This can not only ensure the purity of the transmission, but also avoid the blockage or damage caused by the accumulation of materials in the high-pressure gas chamber 102.
