Description

Technical Field

[0001] This utility model belongs to the field of dust filtration pipeline technology, and specifically relates to a dust filtration pipeline. Background Technology

[0002] Dust filtration ducts are an important component of industrial ventilation and air purification systems, primarily used to remove dust particles from the air. Dust filtration ducts are mostly composed of metal pipes and filter elements. When gas passes through the dust filtration duct, impurities in the gas are filtered by the filter elements, achieving gas purification. However, due to factors such as gas density and flow rate within the duct, uneven gas distribution can occur. When gas distribution is uneven, the filter elements may experience excessive wear in areas of higher gas density, leading to decreased filtration efficiency. Furthermore, during long-term use, filters in the later stages of their lifespan often experience reduced filtration efficiency due to increased impurities inside the filter element, thus lowering the quality of gas filtration. Utility Model Content

[0003] This utility model provides a dust filter pipe that avoids the problem of excessive wear and reduced filtration efficiency caused by uneven contact between the gas and the multi-pleated gas filter cloth during gas transportation. At the same time, it enables the central area of ​​the multi-pleated gas filter cloth to maintain a good filtration state for a longer period of time, and avoids large-area clogging of the multi-pleated gas filter cloth, which helps to improve the overall filtration effect of the pipe.

[0004] This utility model provides the following technical solution: a dust filtration pipe, including an exhaust pipe, an air inlet pipe on one side of the exhaust pipe, and a connecting pipe rotatably connected between the exhaust pipe and the air inlet pipe. A first transmission gear ring is fixedly connected to the outside of the connecting pipe, and a multi-pleated gas filter cloth is fixedly connected inside the connecting pipe, with the multi-pleated gas filter cloth located on one side of the first transmission gear ring. A second transmission gear ring is meshed with the outside of the first transmission gear ring, and a drive motor is provided on one side of the second transmission gear ring. The output end of the drive motor is fixedly connected to one side of the second transmission gear ring.

[0005] The bottom of the drive motor is fixedly connected to a motor mounting base.

[0006] The bottom of the motor mounting base is fixedly connected to a reinforcing support base.

[0007] Both the exhaust pipe and the intake pipe are fixedly connected to annular connecting seats on their outer sides.

[0008] The bottom of the annular connecting seat is fixedly connected to a support base.

[0009] Both ends of the connecting pipe are fixedly connected to rotating connecting seats, and the connecting pipe is rotatably connected to the exhaust pipe and the intake pipe through the rotating connecting seats.

[0010] Both the exhaust pipe and the intake pipe are fixedly connected to an annular sealing seat at one end.

[0011] The connecting pipe has a dust collection groove at the bottom of its inner cavity.

[0012] The beneficial effects of this invention are as follows: With the cooperation of the connecting pipe, the first transmission gear ring, the multi-pleated gas filter cloth, and the second transmission gear ring, the entire filtration and purification surface of the multi-pleated gas filter cloth can be uniformly contacted with the gas in the pipeline. This avoids the problem of excessive wear and reduced filtration efficiency caused by uneven contact between the gas and the multi-pleated gas filter cloth during gas transport. Simultaneously, the multi-pleated gas filter cloth rotates between the inlet and outlet pipes during gas transport, allowing the centrifugal force generated during rotation to throw the adsorbed impurities inside the multi-pleated gas filter cloth to both sides. This ensures that the central area of ​​the multi-pleated gas filter cloth maintains a good filtration state for a longer period, while preventing large-area clogging and improving the overall filtration effect of the pipeline.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0018] Please see Figures 1-3 The present invention provides the following technical solution: a dust filter pipe, including an exhaust pipe 1, an air inlet pipe 11 on one side of the exhaust pipe 1, and a connecting pipe 2 rotatably connected between the exhaust pipe 1 and the air inlet pipe 11. A first transmission gear ring 21 is fixedly connected to the outside of the connecting pipe 2. A multi-pleated gas filter cloth 22 is fixedly connected inside the connecting pipe 2, and the multi-pleated gas filter cloth 22 is located on one side of the first transmission gear ring 21. A second transmission gear ring 23 is meshed with the outside of the first transmission gear ring 21, and a drive motor 3 is provided on one side of the second transmission gear ring 23. The output end of the drive motor 3 is fixedly connected to one side of the second transmission gear ring 23.

[0019] In this implementation scheme: the exhaust pipe 1 and the intake pipe 11 form the outer frame of the entire dust filtration pipeline, providing a channel for gas transportation and a connecting carrier for the connecting pipe 2. The connecting pipe 2 serves as a connecting carrier for the multi-pleated gas filter cloth 22, which purifies impurities in the gas transported from the intake pipe 11. When the gas from the intake pipe 11 passes through the multi-pleated gas filter cloth 22, impurities in the gas are intercepted and adsorbed, thus purifying the gas. The first transmission gear ring 21, located outside the connecting pipe 2, forms a transmission component that drives the connecting pipe 2 to rotate between the intake pipe 11 and the exhaust pipe 1, in cooperation with the second transmission gear ring 23. When the connecting pipe 2 and the multi-pleated gas filter cloth 22 rotate during gas transportation via the first transmission gear ring 21 and the second transmission gear ring 23, the entire filtration and purification surface of the multi-pleated gas filter cloth 22 is evenly contacted with the gas in the pipeline. The pleated gas filter cloth 22 has relatively uniform contact with the gas, which can avoid the problem of excessive local wear and reduced filtration and purification effect of the pleated gas filter cloth 22 due to uneven contact between the gas and the pleated gas filter cloth 22 during the gas transportation process. At the same time, the pleated gas filter cloth 22 rotates between the inlet pipe 11 and the outlet pipe 1 during the gas transportation process. This allows the impurities adsorbed inside the pleated gas filter cloth 22 to be thrown to both sides of the pleated gas filter cloth 22 by the centrifugal force generated during the rotation. This allows the central area of ​​the pleated gas filter cloth 22 to maintain a good filtration state for a longer period of time, and at the same time avoids large-area blockage of the pleated gas filter cloth 22, which is conducive to improving the filtration effect of the entire pipeline. The drive motor 3 installed on one side of the second transmission gear ring 23 is used to drive the second transmission gear ring 23 to rotate. During the gas filtration process, the second transmission gear ring 23 is rotated by turning on the drive motor 3.

[0020] A motor mounting base 31 is fixedly connected to the bottom of the drive motor 3; wherein the motor mounting base 31 is used to provide a connection carrier for the drive motor 3 and to provide support for the drive motor 3.

[0021] A reinforcing support 32 is fixedly connected to the bottom of the motor mounting base 31; the reinforcing support 32 is used to support the motor mounting base 31 and to install it with the mounting surface.

[0022] Both the exhaust pipe 1 and the intake pipe 11 are fixedly connected to annular connecting seats 12 on their outer sides, and a support base 121 is fixedly connected to the bottom of the annular connecting seats 12; wherein the annular connecting seats 12 and the support base 121 cooperate with each other to form a connecting component that supports the exhaust pipe 1 and the intake pipe 11.

[0023] Both ends of the connecting pipe 2 are fixedly connected to rotating connecting seats 24, and the connecting pipe 2 is rotatably connected to the exhaust pipe 1 and the intake pipe 11 through the rotating connecting seats 24; wherein the rotating connecting seats 24 are used to provide a carrier for connecting the connecting pipe 2 with the intake pipe 11 and the exhaust pipe 1.

[0024] An annular sealing seat 13 is fixedly connected to one end of both the exhaust pipe 1 and the intake pipe 11; the annular sealing seat 13 serves to seal.

[0025] A dust collection groove 25 is provided at the bottom of the inner cavity of the connecting pipe 2; the dust collection groove 25 is used to collect particulate impurities that fall into the multi-pleated gas filter cloth 22.

[0026] The working principle and usage process of this utility model are as follows: When installing the entire dust filter pipeline, the connection between the entire dust filter pipeline and the external pipeline is completed through the inlet pipe 11 and the exhaust pipe 1. During installation, the inlet pipe 11 is connected to the inlet end of the external pipeline, and the exhaust pipe 1 is connected to the end of the outlet pipe of the external pipeline. When the gas is purified, the drive motor 3 is turned on. The second transmission gear ring 23 rotates under the drive of the drive motor 3. At the same time, when the second transmission gear ring 23 rotates, it can drive the connecting pipe 2 to rotate between the exhaust pipe 1 and the inlet pipe 11 through the first transmission gear ring 21. At this time, when the multi-pleated gas filter cloth 22 rotates during the gas transportation process, it can make the entire multi-pleated gas filter cloth 2... The filter surface of the filter cloth 22 is in uniform contact with the gas in the pipeline. The relatively uniform contact between the multi-pleated gas filter cloth 22 and the gas can avoid the problem of excessive local wear and reduced filtration effect of the multi-pleated gas filter cloth 22 due to uneven contact between the gas and the multi-pleated gas filter cloth 22 during the gas transportation process. At the same time, the multi-pleated gas filter cloth 22 rotates between the inlet pipe 11 and the outlet pipe 1 during the gas transportation process. This allows the impurities adsorbed inside the multi-pleated gas filter cloth 22 to be thrown to both sides of the multi-pleated gas filter cloth 22 by the centrifugal force generated during the rotation of the multi-pleated gas filter cloth 22. This allows the central area of ​​the multi-pleated gas filter cloth 22 to maintain a good filtration state for a longer period of time.
