Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically an anti-clogging dust collector filter bag. Background Technology

[0002] Dust collector filter bags, also known as dust bags, are core components of dust collection equipment. Structurally, they are typically bag-shaped and made of specific filter materials. Functionally, they are primarily used to separate dust particles from gases, thereby purifying the air. Currently, dust collector filter bags are widely used in various dust collection devices in industrial production processes to filter dust from gases and purify the air.

[0003] Utility model patent application number CN202222746508.9 discloses an anti-adhesion, easy-to-clean dust collector filter bag. This filter bag includes a movable dust collection bin; a suction mechanism installed on top of the dust collection bin to draw external dust into the bin; and a filter bag body installed inside the dust collection bin and below the suction mechanism. A ring-shaped mounting seat is installed at the top opening of the filter bag body. This utility model, through a connecting mechanism, allows a ball to be suspended and installed inside the filter bag body. When the suction mechanism is activated, the gas entering the dust collection bin passes through the ball, causing the connecting rod to rotate back and forth on the fixed rod, thereby causing the ball to strike the filter bag body and knock off the dust adsorbed on it. This solves the problem of existing filter bags easily adsorbing dust, leading to a reduction in filtration efficiency.

[0004] Although the anti-adhesion and easy-to-clean dust collector filter bag has the effect of cleaning the surface of the dust collector filter bag, the device still has limitations in actual use: the cleaning method of the ball relies on the gas flow to drive it. When the operating conditions of the dust collector change, such as unstable gas flow or large pressure fluctuations, the rotation and impact state of the ball will also change. It may even cause the ball to jam or fail to rotate normally, making it difficult to guarantee the cleaning effect and affecting the stable operation of the dust collector. In view of this, we propose an anti-clogging dust collector filter bag. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide an anti-clogging dust collector filter bag that effectively removes adhering dust by continuously and evenly striking the surface of the filter bag with a swing rod, thus avoiding filter bag clogging caused by untimely dust removal.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-clogging dust collector filter bag includes:

[0008] The machine body has a dust removal chamber inside;

[0009] A fixing ring is fixed to the top of the dust collection chamber; a filter bag is fixed to the bottom of the fixing ring.

[0010] The dust removal section is used to clean the dust filter bag to prevent it from clogging. It includes two symmetrical fixed plates that are fixed to the inner wall of the dust removal chamber. A rotating shaft is rotatably installed at one corner of the fixed plate. The rear end of the rotating shaft passes through the rear end face of the machine body. A sprocket is coaxially connected to the rear end of the rotating shaft. A chain is sleeved between the two sprockets.

[0011] The front side of the fixed plate is equipped with a swing arm that can swing back and forth to strike the surface of the dust bag for dust removal. A connecting ring is fixed at the bottom end of the swing arm, and the connecting ring is coaxially connected to the rotating shaft. A pin is fixed on the outer wall of the swing arm near the middle.

[0012] A motor is installed at the rear end of the fixed plate on the right side. The output shaft of the motor passes through the fixed plate. The front end of the output shaft of the motor is coaxially connected to a transmission plate. A short shaft is fixed at the top of the front end face of the transmission plate. A connecting plate is provided between the transmission plate and the rocker arm. Both ends of the connecting plate are provided with shaft holes, and the shaft holes on both sides are rotatably connected to the short shaft and the pin, respectively.

[0013] In addition, the anti-clogging dust collector filter bag proposed in the application may also have the following additional technical features:

[0014] Specifically, the fixing ring is fixedly connected to the top of the dust removal chamber by bolts, and the top of the filter bag is tightly bonded to the fixing ring;

[0015] In this setup, bolted connections facilitate easy installation and disassembly, making replacement and maintenance convenient; adhesive bonding ensures a tight seal, preventing gas leakage, and bolt fixing enhances structural stability, ensuring effective dust removal.

[0016] Specifically, the dust filter bag is made of polyester needle-punched felt, and the length of the dust filter bag is adapted to the height of the dust collection chamber;

[0017] In this setup, the polyester needle-punched felt exhibits excellent filtration performance and mechanical strength, effectively intercepting dust. Simultaneously, the appropriate length increases the filtration area, enhancing dust removal efficiency and avoiding installation problems and filtration dead zones.

[0018] Specifically, the rear side wall of the machine body is fixedly connected to a hollow protective cover by bolts, and the sprocket and chain are installed inside the protective cover;

[0019] In this setup, the protective cover isolates dust and debris, reduces wear and tear on components, and ensures smooth transmission.

[0020] Specifically, a dust cover is bolted to the rear end face of the fixing plate on the right side, and the dust cover covers the outside of the motor;

[0021] In this setting, the dust cover effectively prevents dust from entering the motor, extending the motor's service life.

[0022] Specifically, the right end of the dust cover is open, and the right end face of the machine body has multiple heat dissipation grooves that communicate with the inner cavity of the dust cover.

[0023] This design ensures both dust protection and facilitates heat dissipation from the motor.

[0024] Specifically, the rocker arm, connecting ring, and pin are integrally formed structures, and all three are made of stainless steel.

[0025] In this design, the one-piece molding and stainless steel material reduces connection gaps and enhances structural strength; at the same time, the material is corrosion-resistant and wear-resistant, adaptable to dust removal environments, reduces the risk of damage, and ensures long-term stable dust removal performance.

[0026] Specifically, a bearing is provided at the rotatable connection between the rotating shaft and the fixed plate, and the rotating shaft is made of alloy steel;

[0027] In this configuration, the bearings reduce rotational friction, making operation more flexible and reducing energy consumption; the high strength and toughness of the alloy steel can withstand the forces exerted by the components, ensuring the stable operation of the transmission system.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] 1. The cleaning section features a motor-driven transmission plate that rotates, precisely controlling the swing arm's rhythmic reciprocating oscillations via a connecting plate. The bottom of the swing arm is coaxially connected to the rotating shaft via a connecting ring, while the central pin engages with the connecting plate, forming a stable lever transmission system that ensures efficient and stable power transmission to the swing arm's striking end. This design allows the swing arm to continuously and evenly strike the surface of the dust bag, effectively removing adhering dust and preventing filter bag clogging due to untimely cleaning. Unaffected by gas flow and pressure fluctuations, this design ensures continuous and effective cleaning of the dust bag surface, guaranteeing cleaning performance and maintaining the long-term, stable, and efficient operation of the dust collection equipment.

[0030] 2. A protective cover is installed on the rear side wall of the machine body to house the sprocket and chain. A dust cover is installed at the rear end of the right fixed plate to cover the motor. The dust cover is open at the right end and a heat dissipation groove is provided on the right end face of the machine body. This can prevent dust and other impurities from entering and affecting the normal operation of the transmission components and motor, and also ensure the heat dissipation of the motor, thereby improving the reliability and safety of the equipment operation.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] This embodiment provides a technical solution:

[0043] Please see Figures 1-6 As shown, an anti-clogging dust collector filter bag includes a body with a dust collection chamber inside; a fixing ring 1 fixed to the top of the dust collection chamber; and a filter bag 2 fixed to the bottom of the fixing ring 1.

[0044] Specifically, the fixing ring 1 is fixedly connected to the top of the dust collection chamber by bolts, and the top of the dust bag 2 is tightly bonded to the fixing ring 1. This connection method is convenient for installation and disassembly, facilitating the replacement and maintenance of the dust bag 2; at the same time, the tight bonding ensures the sealing of the connection, preventing the leakage of dust-laden gas and ensuring the dust collection effect, while the bolt fixing provides reliable mechanical strength, ensuring the stability of the structure.

[0045] Specifically, the dust bag 2 is made of polyester needle-punched felt, and its length is adapted to the height of the dust collection chamber. Polyester needle-punched felt has good filtration performance and mechanical strength, and can efficiently intercept dust; the adapted length allows the dust bag 2 to fully unfold in the dust collection chamber, increasing the filtration area and improving dust collection efficiency, while avoiding installation problems or filtration dead zones caused by improper length.

[0046] Please see Figures 1-6 As shown, the dust removal section 3 is used to clean the dust filter bag 2 to prevent it from clogging. It includes two symmetrical fixed plates 30 fixed to the inner wall of the dust removal chamber. A rotating shaft 31 is rotatably mounted at one corner of each fixed plate 30. The rear end of the rotating shaft 31 passes through the rear end face of the machine body. A sprocket 32 ​​is coaxially keyed to the rear end of the rotating shaft 31. A chain 33 is sleeved between the two sprockets 32. Each fixed plate 30 has a swing arm 34 on its front side that can reciprocate to strike the surface of the dust filter bag 2 for dust removal. A connecting ring 340 is fixed to the bottom end of the swing arm 34. 340 is coaxially connected to the rotating shaft 31; a pin 341 is fixed near the middle of the outer wall of the rocker arm 34; a motor 37 is installed at the rear end of the fixed plate 30 on the right side, the output shaft of the motor 37 passes through the fixed plate 30, and the front end of the output shaft of the motor 37 is coaxially keyed to the transmission plate 36, and a short shaft 360 is fixed at the top end of the front end face of the transmission plate 36; a connecting plate 35 is provided between the transmission plate 36 and the rocker arm 34, and shaft holes are opened at both ends of the connecting plate 35, and the shaft holes on both sides are rotatably connected to the short shaft 360 and the pin 341 respectively.

[0047] With the above configuration and the design of the dust removal section 3, the two fixed plates 30, in conjunction with the rotating shaft 31, sprocket 32, and chain 33, drive the swing arm 34 to reciprocate and strike the dust bag 2 under the drive of the motor 37. This structure can effectively remove dust from the surface of the dust bag 2, prevent clogging, ensure dust removal efficiency, extend the service life of the dust bag, and the mechanical transmission structure is stable, reliable, and easy to maintain.

[0048] Specifically, a hollow protective cover is bolted to the rear wall of the machine body, and both the sprocket 32 ​​and the chain 33 are installed inside the protective cover. This design not only prevents dust and debris from entering the transmission components and avoids wear and jamming of the sprocket 32 ​​and chain 33 due to external factors, ensuring the smooth operation of the transmission system, but also reduces external interference to the transmission components, improves the overall stability and safety of the equipment, and reduces the frequency of maintenance.

[0049] Specifically, a dust cover 38 is bolted to the rear end of the mounting plate 30 on the right side, covering the exterior of the motor 37. This effectively isolates dust, preventing it from entering the motor 37 and thus avoiding malfunctions due to dust accumulation, thereby extending the motor's lifespan.

[0050] Specifically, the right end of the dust cover 38 is open, and the right end face of the machine body has multiple heat dissipation slots that communicate with the inner cavity of the dust cover 38. The open design of the dust cover 38, in conjunction with the heat dissipation slots of the machine body, ensures good heat dissipation performance of the motor 37 and maintains its stable operation.

[0051] Specifically, the rocker arm 34, connecting ring 340, and pin 341 are integrally formed structures, all made of stainless steel. This integral design increases the reliability and stability of the connection between the rocker arm 34, connecting ring 340, and pin 341, while the stainless steel material offers excellent corrosion resistance and wear resistance, making it suitable for dusty environments.

[0052] Specifically, a bearing is provided at the rotational connection between the rotating shaft 31 and the fixed plate 30, and the rotating shaft 31 is made of alloy steel. The use of bearings reduces the frictional resistance when the rotating shaft 31 rotates, making the rotation more flexible and smooth, and reducing energy loss; the alloy steel rotating shaft 31 has high strength and good toughness, and can withstand the force of components such as the swing arm 34, ensuring the stable and reliable operation of the dust removal unit 3 transmission system.

[0053] Understandably, dust falling from the dust bag 2 will not affect the transmission of structures such as the connecting plate 35, swing arm 34, and transmission plate 36. First, from a layout perspective, the transmission components such as the connecting plate 35, swing arm 34, and transmission plate 36 are located on the side of the dust bag 2. Under the influence of gravity, dust mainly falls vertically along the dust bag, making it difficult for it to accumulate directly on the surface of these components. Second, the hollow protective cover on the rear side wall of the machine encloses the sprocket 32 ​​and chain 33, effectively preventing dust from entering the critical transmission area and reducing the potential interference of dust on connected components such as the shaft 31 and swing arm 34. Furthermore, the dust cover 38 at the rear end of the right-side fixing plate 30 covers the motor 37, preventing dust from affecting the power source. The opening of the dust cover 38 is designed in conjunction with the heat dissipation slots to prevent dust from being attracted due to internal airflow turbulence. In addition, the swing arm 34, connecting ring 340 and pin 341 are made of one-piece molded stainless steel with a smooth and flat surface. Even if a small amount of dust is attached, the swing arm 34 can shake off the dust during the reciprocating swing. At the same time, the bearing between the rotating shaft 31 and the fixed plate 30 ensures flexible rotation and further reduces the risk of jamming caused by dust, thereby ensuring smooth transmission of the connecting plate 35, swing arm 34 and transmission plate 36.

[0054] It is worth noting that the motor 37 involved in this embodiment is a conventional technology and will not be described in detail here.

[0055] In practical use, firstly, the user turns on the power to the motor 37, and the motor 37 starts. Its output shaft drives the transmission plate 36, which is connected to the coaxial key, to rotate. The short shaft 360 on the front end of the transmission plate 36 moves accordingly. Since the short shaft 360 is rotatably connected to the pin 341 through the connecting plate 35, the rotational motion is converted into the reciprocating swing of the swing arm 34. Since the connecting ring 340 at the bottom of the swing arm 34 is coaxially connected to the rotating shaft 31, it can drive the rotating shaft 31 to rotate on the fixed plate 30. Next, the sprocket 32 ​​at the rear end of the rotating shaft 31 realizes the synchronous rotation of the two rotating shafts 31 through the chain 33, ensuring that the two swing arms 34 swing synchronously. Finally, the swinging swing arm 34 continuously hits the surface of the dust bag 2, shaking off the attached dust and preventing the dust bag 2 from clogging.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
