Description

Technical Field

[0001] This invention relates to the field of dust filtration equipment technology, specifically to a novel dust filtration device. Background Technology

[0002] Dust pollution is a common environmental problem in industrial production processes, especially in industries such as textiles, wood processing, grain processing, chemicals, and metal processing, as well as in the application of dry and wet wood pulp and wood pulp boards. These processes generate large amounts of dust and fibrous pollutants, which not only pollute the working environment and affect employee health, but also damage production equipment, reduce product quality, and may even cause safety accidents such as explosions under certain conditions. Therefore, efficient and reliable dust filtration equipment is of great significance for ensuring production safety, improving the working environment, and protecting employee health. In specific industries such as textiles and chemical fibers, the lint pollutants generated during the production process are characterized by long fibers, easy entanglement, and difficulty in removal, which puts higher demands on filtration equipment. When existing filtration equipment deals with these pollutants, lint often accumulates and entangles on the filter screen, causing the equipment resistance to rise sharply, the filtration effect to deteriorate rapidly, and frequent manual cleaning to be required, which seriously affects production efficiency and equipment reliability. Currently, most dust filtration equipment on the market uses fixed filter screens or filter bags, which capture dust particles through mechanisms such as interception, inertial impaction, and diffusion. Although these devices have a simple structure, they have significant shortcomings when dealing with dust-laden gases containing fibrous pollutants (such as lint): First, fibrous pollutants tend to accumulate on the surface of the filter media, forming a dense covering layer, which leads to a rapid increase in equipment resistance, increased energy consumption, and decreased filtration efficiency. Second, traditional fixed filtration equipment requires frequent shutdowns for cleaning or replacement of the filter media, affecting production continuity and increasing maintenance costs. Third, the cleaning systems of most devices (such as pulse backflushing) have limited effectiveness in removing fibrous pollutants, which tend to remain on the surface of the filter media, leading to permanent clogging over time. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a novel dust filtration device. It solves the problem that current dust filtration equipment on the market primarily employs fixed filter screens or filter bags, capturing dust particles through mechanisms such as interception, inertial impaction, and diffusion. While these devices are simple in structure, they have significant limitations when handling dust-laden gases containing fibrous pollutants (such as lint): First, fibrous pollutants easily accumulate on the surface of the filter media, forming a dense covering layer, leading to a rapid increase in equipment resistance, increased energy consumption, and decreased filtration efficiency. Second, traditional fixed filtration equipment requires frequent shutdowns for cleaning or replacement of the filter media, affecting production continuity and increasing maintenance costs. Third, most equipment's cleaning systems (such as pulse jet cleaning) have limited effectiveness in removing fibrous pollutants, easily leaving residues on the filter media surface, leading to permanent clogging over time.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel dust filtration device, comprising a housing, an air inlet on the lower wall of the housing, an air outlet on the side wall of the housing, support cylinders fixedly installed on the two inner walls of the housing respectively, the support cylinders covering the air outlets, a filter cylinder rotatably installed between the support cylinders, a pair of first support wheels on the lower inner wall of the housing, a pair of second support wheels on the lower inner wall of the housing located on one side of the first support wheels, the filter cylinder contacting the first and second support wheels, a driving assembly on the other outer wall of the housing connected to the pair of second support wheels, a pressing assembly on the upper inner wall of the housing in contact with the filter cylinder, and a dust suction assembly inside the housing for adsorbing lint on the outer wall of the filter cylinder.

A spring is fixedly mounted between the bearing plate and the mounting plate.

[0007] Preferably, the vacuuming assembly includes a pair of L-shaped plates, which are respectively fixedly installed on the outer side walls of the housing. A pair of support seats are fixedly installed on each L-shaped plate, and a second rotating rod is rotatably mounted between the support seats. Both ends of the second rotating rod pass through the support seats. A first drive sprocket is fixedly installed on one end of the second rotating rod, and a first drive chain connects the first drive sprockets. A second drive sprocket is fixedly installed on the other end of the second rotating rod, and a second drive chain connects the second drive sprockets. The first and second drive chains pass through the outer side walls of the housing, respectively, and are located inside and outside the filter cylinder. A first slide rail and a second slide rail are fixedly installed between the inner side walls of the housing and below the first and second drive chains. The first and second slide rails are respectively fixed with... A first slider and a second slider are fixedly installed on the housing. The first slider and the second slider are respectively fixedly installed on the first transmission chain and the second transmission chain. An air outlet nozzle and a collection nozzle are respectively fixedly installed on the first slider and the second slider. An air inlet pipe is fixedly installed on the upper wall of the housing. A pipe is fixedly installed at the lower end of the air inlet pipe. The pipe passes through the side wall of the housing and is located inside the filter screen. An exhaust pipe is fixedly installed on the upper wall of the housing. Flexible conduits are connected between the pipe and the air outlet nozzle and between the exhaust pipe and the collection nozzle. A second motor is fixedly installed on the other side wall of the housing and above the L-shaped plate. A second reducer is fixedly installed on the drive end of the second motor. A third sprocket is fixedly installed on the output end of the reducer. A fourth sprocket is fixedly installed on the second rotating rod and on one side of the second transmission sprocket.

[0008] Preferably, a concave plate is fixedly installed on the front wall of the box, and the flexible conduit between the exhaust pipe and the collecting nozzle is located in the gap between the concave plate and the front wall of the box.

[0009] Preferably, an arc-shaped plate is fixedly installed on the lower wall of the box, and the arc-shaped plate is located above the air inlet.

[0010] Beneficial effects This invention provides a novel dust filtration device, which has the following advantages: This invention employs a rotary filter cylinder design. A first motor drives a support wheel to continuously rotate the filter cylinder, ensuring that dust and fibrous contaminants in the dusty airflow are evenly distributed on the filter cylinder surface. This avoids the problem of a sharp increase in resistance caused by localized blockages in traditional fixed filtration equipment. Simultaneously, the innovative dust collection component, through an internal and external dual-chain transmission system, drives the exhaust nozzle and collection nozzle to reciprocate along the filter cylinder surface, forming a continuous blowing and suction cleaning action. This effectively solves the technical problem of fibrous contaminants being easily entangled and difficult to remove. This simultaneous filtration and cleaning working mode ensures long-term stable operation of the equipment without frequent shutdowns for cleaning, significantly improving production efficiency.

[0011] The dust collection component of this invention adopts a unique dual-chain transmission structure. The first and second transmission chains are located on the inner and outer sides of the filter cylinder, respectively, driving the slider equipped with an exhaust nozzle and a collection nozzle to reciprocate along the slide rail. The exhaust nozzle is connected to the air inlet pipe through a flexible conduit, and the jet of air blows up the fibrous contaminants attached to the surface of the filter cylinder. At the same time, the collection nozzle is connected to an external air extraction device through an exhaust pipe to promptly remove the blown contaminants. This "blowing and suction combination" cleaning method has a strong removal effect on fibrous contaminants and effectively prevents the filter cylinder from clogging. It is particularly suitable for treating lint and other contaminants generated by the textile and chemical fiber industries.

[0012] This invention ensures the stability and balance of the filter cylinder during rotation through the synergistic action of multiple sets of support wheels and clamping components. The first and second support wheels support the filter cylinder from below, while the upper clamping component, through a spring-loaded pressure wheel, maintains constant contact with the filter cylinder, effectively suppressing vibration and offset of the filter cylinder during rotation. This multi-point, multi-directional support and clamping system not only improves the smoothness of equipment operation but also extends the service life of the filter cylinder and related transmission components, reducing maintenance frequency and costs.

[0013] The cleaning system of the present invention can precisely adjust the movement trajectory and speed of the air outlet nozzle and the collection nozzle on the surface of the filter cylinder by controlling the forward and reverse rotation of the second motor. When the increased resistance of the equipment is detected, the cleaning system can be started to clean the filter cylinder in a comprehensive or partial manner. During normal operation, it can also perform intermittent cleaning according to a preset program. This adjustable cleaning method not only ensures the cleaning effect, but also avoids energy waste caused by over-cleaning, achieving the best balance between energy saving and high efficiency.

[0014] This invention features an arc-shaped guide plate above the air inlet, which allows the dust-laden airflow to flow evenly along a specific direction onto the surface of the filter cylinder, avoiding problems such as airflow short-circuiting and excessively high local flow velocity. The design of the support cylinder covering the air outlet ensures that the filtered clean gas is discharged in a concentrated manner. This optimized airflow organization not only improves dust capture efficiency but also reduces airflow turbulence inside the equipment, lowers system resistance, thereby reducing fan energy consumption and achieving energy-saving operation.

[0015] This invention, through an innovative combination of rotary filtration and synchronous cleaning, along with a stable support structure and intelligent dust removal control, effectively solves the problems of severe clogging, frequent maintenance, and high energy consumption encountered by traditional dust filtration equipment when dealing with fibrous pollutants. It has significant advantages such as high filtration efficiency, strong anti-clogging ability, stable operation, energy saving and environmental protection, and convenient maintenance. It is particularly suitable for industrial fields that generate fibrous pollutants, such as textiles, chemical fibers, and wood processing, and has important value for promotion and application.

[0029] In this embodiment, an arc-shaped plate 43 is fixedly installed on the lower inner wall of the housing 1, and the arc-shaped plate 43 is located above the air inlet 2.

[0030] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0031] Example: As shown in the accompanying drawings, during use, an elongated hole is provided on the bearing plate 16, and a spring 19 covers the elongated hole. A lead screw is fixedly installed on the lower wall of the mounting plate 15, and the spring 19 is fitted onto the lead screw. The lower end of the lead screw passes through the elongated hole, and a nut is screwed onto the lead screw. By adjusting the nut, the compression degree of the spring 19 is adjusted, so that the pressure roller 18 can fit against the filter cylinder 4 (the number of layers on the filter cylinder 4 is selected according to different working conditions and filtration environment; it can be a single layer or multiple layers). First, hot air carrying lint enters through the air inlet 2. Under the action of the arc plate 43, the hot air and lint flow along the arc of the arc plate 43 towards the filter cylinder 4. At this time, the first motor 9 is started. The first reducer 10 is started, which drives the first sprocket 11 to rotate. Since the first sprocket 11 and the second sprocket 12 are connected by the first chain 13, the second sprocket 12 drives the first rotating rod 7 to rotate. The first rotating rod 7 drives the first support wheel 5 to rotate, and the first support wheel 5 drives the filter cylinder 4 to rotate. The second support wheel 6 supports the rotation of the filter cylinder 4. During the rotation, the filter cylinder 4 will vibrate slightly, which causes the spring 19 to push the bearing plate 16, so that the pressure roller 18 is always in contact with the filter cylinder 4, making the rotation of the filter cylinder 4 more stable. At this time, lint adheres to the outer wall of the filter cylinder 4, and hot air enters the filter cylinder 4. The air is discharged through the air outlet 3. To prevent the filter cylinder 4 from being clogged by lint, the second motor 37 is started. The second motor 37 drives the second reducer 38 to rotate, and the second reducer 38 drives the third sprocket 39 to rotate. The third sprocket 39 is connected to the fourth sprocket 40 by the second chain 41, which in turn causes the fourth sprocket 40 to drive the second rotating rod 22 to rotate. The second rotating rod 22 drives the first transmission sprocket 23 and the second transmission sprocket 25 to rotate, which in turn causes the first transmission chain 24 and the second transmission chain 26 to move. The first transmission chain 24 and the second transmission chain 26 drive the first slider 29 and the second slider 30 to move along the first slide rail 27 and the second slide rail 28. The two slide rails 28 move, at which time the air inlet pipe 33 is connected to the external blower and the exhaust pipe 35 is connected to the external air extraction device, thereby forming a circulating airflow between the air outlet nozzle 31 and the exhaust nozzle, so that the lint on the filter screen cylinder 4 is sucked away by the exhaust nozzle. When the first slider 29 and the second slider 30 move to one end of the slide rail, the first motor 9 is started to make the filter screen cylinder 4 rotate, and the second motor 37 reverses, so that the first slider 29 and the second slider 30 move in the opposite direction. This process is repeated, and the first motor 9 rotates intermittently, and the air outlet nozzle 31 and the collection nozzle 32 move back and forth, so that the outer wall surface of the filter screen cylinder 4 is continuously cleaned. The filter screen cylinder is made of 304 stainless steel 100 mesh.

[0032] Example 2: A novel dust filtration device includes a housing 1. An air inlet 2 is provided on the lower wall of the housing 1, and an air outlet 3 is provided on the side wall of the housing 1. Support cylinders are fixedly installed on both inner side walls of the housing 1, covering the air outlets 3. A filter cylinder 4 is rotatably installed between the support cylinders. A pair of first support wheels 5 are provided on the lower inner wall of the housing 1, and a pair of second support wheels 6 are provided on the lower inner wall of the housing 1, located to one side of the first support wheels 5. The filter cylinder 4 contacts the first support wheels 5 and the second support wheels 6. A driving assembly is provided on the other outer side wall of the housing 1, connected to the pair of second support wheels 6. A pressing assembly is provided on the upper inner wall of the housing 1. The clamping assembly contacts the filter cylinder 4. The driving assembly and clamping assembly are the same as in Embodiment 1. The support base 21, second rotating rod 22, first transmission sprocket 23, first transmission chain 24, second transmission sprocket 25, second transmission chain 26, first slide rail 27, second slide rail 28, first slider 29, second slider 30, second motor 37, second reducer 38, third sprocket 39, fourth sprocket 40, second chain 41, and concave plate 42 in the dust collection assembly are omitted. The lengths of the collecting nozzle 32 and the air outlet nozzle 31 are the same as the length of the filter cylinder 4. It can be seen that when the filter cylinder 4 rotates, the collecting nozzle 32 and the air outlet nozzle 31 clean the filter cylinder 4 at the same time.
