Description

An easy-to-clean bag filter Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a baghouse dust collector that is easy to clean. Background Technology

[0002] A bag filter dust collector is a high-efficiency purification device that uses fiber filter bags to capture dust particles in gas, achieving gas-solid separation through physical filtration principles. Long-term use of a bag filter dust collector requires regular cleaning of the filter bags.

[0003] The utility model with announcement number CN221752642U discloses an easy-to-clean bag filter, including a box body, an air inlet on the top of the box body, an air outlet on the side wall of the box body, an induced draft fan installed on the air outlet, a filter chamber inside the box body, a cleaning component installed on the inner wall of the filter chamber, and a filter cloth layer inside the filter chamber.

[0004] The above technical solution utilizes a telescopic motor to control the output of a telescopic screw, pushing the mounting frame to adjust the position of the vibrating component, ensuring it adheres to the filter cloth layer. Then, the vibrating motor is activated, driving the vibrating component to generate high-frequency vibration, causing dust on the filter cloth layer to fall. A collection box collects the dust, which can be pulled out from the collection layer using a lever as a force point for cleaning. This structure allows for faster cleaning of dust on the filter cloth layer, ensuring the equipment's working efficiency. However, when cleaning the filter cloth, single vibration is insufficient for effectively removing stubborn dust particles stuck in the filter cloth and increasing the thoroughness of cleaning. External force is used to remove dust stuck in the gaps of the filter cloth, increasing the stability of the cleaning process. Summary of the Invention

[0005] The purpose of this invention is to provide a bag filter that is easy to clean, so as to solve the problems mentioned in the background art.

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

[0007] A bag filter dust collector that is easy to clean includes a housing, a top cover on the top of the housing, a guide hopper at the bottom of the housing, a dust collection box at the bottom of the guide hopper, a slot on the front face of the dust collection box, a drawer in the slot, U-shaped plates symmetrically arranged on the inner wall of the housing, a movable tray near the top of the housing, a filter cloth in the middle of the movable tray, and a drive assembly in the middle of the rear face of the housing.

[0008] The drive assembly includes a crankshaft disk coaxially connected to the motor and the motor's output shaft, and rotating rods symmetrically arranged on both sides of the motor. The rotating rods extend into the housing and are symmetrically supported by support rods. A striking rod is provided near the end of each of the two support rods. A protruding post is provided on the crankshaft disk, and a crank rod is provided above the protruding post. A pivot seat is provided on the lower surface of the movable support plate near the edge, corresponding to the top of the crank rod. A connecting rod is also provided between the rotating rod and the motor's output shaft.

[0009] Furthermore, arc-shaped plates are provided on both sides of the box corresponding to the rotating rod, and an air intake pipe communicating with the interior is provided near the bottom on the left end of the box, with a one-way valve on the left end of the air intake pipe.

[0010] In this invention, the combination of the arc-shaped plate and the box increases the internal space of the box, which helps the striking rod to pass through the inner side of the arc-shaped plate when the rotating rod continues to rotate. This facilitates the continuous rotation of the striking rod to beat the filter cloth and remove dust. The outer end of the air inlet pipe is connected to the external air delivery pipe, and with the cooperation of the one-way valve, it is prevented that the air inside the box flows back from the air inlet pipe to the external air delivery pipe.

[0011] Specifically, an exhaust pipe communicating with the interior is provided near the top of the right end face of the box, the top of the guide bucket is welded and fixed to the bottom of the box, an exhaust pipe communicating with the interior is provided near the bottom of the right side of the guide bucket, and a filter screen is provided at the intersection of the exhaust pipe and the guide bucket.

[0012] In this invention, the exhaust pipe, in conjunction with the dust removal filter on the inner wall of the chamber, continuously discharges the air after dust removal. The guide bucket concentrates the dust particles falling under gravity at the bottom. The outer end of the exhaust pipe is connected to an external exhaust fan to continuously exhaust the interior, accelerating the falling speed of the internal dust. With the help of the filter screen, the amount of dust extracted and discharged is reduced.

[0013] It should be noted that the bottom of the guide hopper is welded and fixed to the top of the dust collection box, and the inside of the dust collection box is connected to the inside of the guide hopper. The width of the inner wall of the slot is adapted to the width of the outer wall of the drawer, and a handle is provided on the outer wall of the drawer.

[0014] In this invention, the drawer is inserted into a slot, where fallen dust particles are collected in a concentrated manner, facilitating centralized processing. A handle is fitted on the drawer to provide a point of leverage, making it easy to remove or install the drawer. The outer wall of the drawer fits tightly against the slot, fixing the drawer in position within the slot under frictional force. This prevents air compression from squeezing the drawer out of the slot during dust removal, thus avoiding interference with dust filtration.

[0015] Furthermore, the outer wall of the U-shaped plate is tightly fitted and welded to the inner wall of the box. Sliding holes are provided near the corners of the U-shaped plate. The width of the outer wall of the movable support plate is adapted to the width of the inner wall of the box. A sliding rod is provided on the lower surface of the movable support plate at the position corresponding to the sliding hole.

[0016] In this invention, the movable pallet is connected to the sliding hole by a sliding rod, which increases the stability of the movable pallet's up and down movement. The width of the outer wall of the movable pallet is matched with the width of the inner wall of the box, and the gap between the movable pallet and the box is small, allowing some air to leak out. The dust particles filtered by the filter cloth are larger than the gap width, so they do not affect the dust removal and filtration of the filter cloth.

[0017] Specifically, the width of the outer wall of the top cover is adapted to the width of the outer wall of the box, a sealing gasket is provided on the lower surface of the top cover, and through holes are provided on the upper surface of the top cover near the four corners. Fixing bolts are provided in the through holes, and screw holes are provided on the top of the box corresponding to the through holes. Handle grooves are provided on both sides of the outer wall of the top cover.

[0018] In this invention, the sealing gasket enhances the tightness of the installation between the top cover and the housing. The fixing bolt passes through the through hole and is threaded into the screw hole, achieving stability in the installation of the top cover and the housing. The handle groove provides a point of leverage, facilitating the opening or installation of the top cover.

[0019] It is worth noting that the motor is fixedly connected to the outer wall of the housing by screws, the output shaft of the motor is rotatably connected to the housing, the output shaft of the motor is welded and fixed to the crankshaft disc, and a first conical tooth is provided on the output shaft of the motor near the crankshaft disc. The bottom of the crank rod is rotatably connected to the protrusion on the crankshaft disc, and the top of the crank rod is rotatably connected to the shaft seat.

[0020] In this invention, the motor is electrically connected to an external power source via a wire. When the control switch on the outer wall of the motor is activated, the output shaft rotates continuously to provide power for the continuous rotation of the crankshaft disc. The crankshaft disc connects to the rotating shaft seat. As the crankshaft disc rotates, it drives the movable tray to move up and down reciprocally, continuously causing the filter cloth to undulate and shake to remove dust.

[0021] Furthermore, the rotating rod is rotatably connected to the box body, the support rod is welded and fixed to the rotating rod, the two ends of the striking rod are respectively welded and fixed to the corresponding ends of the support rod, the rotating rod is also symmetrically provided with limiting blocks, and the outer wall of the limiting block is close to the inner wall of the box body, and the rotating rod extending out of the box body is also provided with a second conical tooth.

[0022] In this invention, a striking rod is attached to the rotating rod. The rotating rod rotates continuously, and the two sets of striking rods continuously strike the outer wall of the filter cloth. The collision force generated during the striking removes the dust particles stuck on the filter cloth. The striking rods on the two sets of rotating rods strike each other in a cross manner, continuously striking the two sides of the filter cloth to remove dust, thereby increasing the dust removal speed.

[0023] In addition, the connecting rod is provided with a third conical tooth at both ends, and a positioning block is provided on the outer wall of the box corresponding to the connecting rod. One of the third conical teeth meshes with the second conical tooth, and the other third conical tooth meshes with the first conical tooth.

[0024] In this invention, the connecting rod is rotatably connected to the positioning block to limit the position of the connecting rod. With the cooperation of the connecting rod with the third conical tooth, the first conical tooth on the output shaft of the motor rotates to drive the second conical tooth to rotate, thereby realizing the synchronous rotation of the crankshaft disk and the rotating rod, so as to realize the dust removal by shaking the filter cloth up and down while simultaneously removing dust by tapping the side.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. This utility model combines a box with a guide hopper and a dust collection box with a drawer with the guide hopper to collect dust falling inside the box. The drive assembly, in conjunction with a crankshaft and crank rod, moves the movable tray up and down. Two rotating rods with striking rods are connected to the first conical gear on the motor output shaft via a connecting rod, so that when the filter cloth shakes up and down to remove dust, it also cross-striks the sides of the filter cloth to remove dust, thus accelerating the dust removal speed of the filter cloth.

[0027] 2. This utility model features a top cover with a sealing gasket, which is fixed to the box body by a fixing bolt. An air inlet pipe with a one-way valve is fitted on the box body to prevent air backflow from affecting the box body. With the help of the exhaust pipe and the filter screen, dust particles are blocked from being sucked out when the air is drawn in, which affects the dust collection. The movable tray is connected to the sliding rod and the sliding hole to realize the stable up and down movement of the movable tray inside the box body. Attached Figure Description

[0046] In this invention, with the help of the exhaust pipe 15, the air after being filtered and dust-removed from the inner wall of the housing 1 is continuously discharged. The guide bucket 10 concentrates the dust particles that fall under gravity at the bottom. The outer end of the exhaust pipe 11 is connected to an external exhaust fan to continuously exhaust the interior, accelerating the speed at which the internal dust falls. With the help of the filter screen 110, the amount of dust extracted and discharged is reduced.

[0047] Specifically, the top of the box 1 is provided with a top cover 3. The width of the outer wall of the top cover 3 is adapted to the width of the outer wall of the box 1.

The outer wall of the drawer 21 fits tightly with the slot 20, and the position of the drawer 21 in the slot 20 is fixed by friction, so as to prevent the air from squeezing the drawer 21 out of the slot 20 during dust removal, which would affect the dust removal and filtration.

[0051] Furthermore, the inner wall of the box 1 is symmetrically provided with U-shaped plates 17, and a movable support plate 16 is provided near the top inside the box 1. A filter cloth 160 is provided in the middle of the movable support plate 16. The outer wall of the U-shaped plate 17 is tightly attached to and welded to the inner wall of the box 1.

A sliding rod 161 is provided on the lower surface of the movable support plate 16 corresponding to the sliding hole 170.

[0052] In this utility model, the movable tray 16 is connected to the sliding hole 170 by the sliding rod 161, which increases the stability of the movable tray 16 moving up and down. The width of the outer wall of the movable tray 16 is adapted to the width of the inner wall of the box 1, and the gap between the movable tray 16 and the box 1 is small, so some air leaks out from the gap. The dust particles filtered by the filter cloth 160 are larger than the gap width, which does not affect the dust removal and filtration of the filter cloth 160.

[0053] Secondly, a drive assembly 4 is provided at the middle of the rear end face of the housing 1. The drive assembly 4 includes a crankshaft disk 400 coaxially connected to a motor 40 and the output shaft of the motor 40, and rotating rods 41 symmetrically provided on both sides of the motor 40.

[0055] In this utility model, the motor 40 is electrically connected to an external power source through a wire. When the control switch on the outer wall of the motor 40 is activated, the output shaft rotates continuously to provide power for the continuous rotation of the crankshaft disk 400. The crank rod 43 connects the crankshaft disk 400 and the rotating shaft seat 162. When the crankshaft disk 400 rotates, it drives the movable support plate 16 to move up and down reciprocally, continuously causing the filter cloth 160 to undulate up and down, thus achieving the shaking effect for dust removal.

[0056] Furthermore, the rotating rod 41 is rotatably connected to the housing 1, the support rod 410 is welded and fixed to the rotating rod 41, the two ends of the striking rod 411 are respectively welded and fixed to the corresponding ends of the support rod 410, the rotating rod 41 is also symmetrically provided with limiting blocks 412, and the outer wall of the limiting block 412 is close to the inner wall of the housing 1, and the rotating rod 41 is also provided with a second conical tooth 413 at one end extending out of the housing 1.

[0057] In this invention, a striking rod 411 is attached to the rotating rod 41.

The collision force generated during the striking removes the dust particles stuck on the filter cloth 160. The striking rods 411 on the two sets of rotating rods 41 strike each other in a cross manner, continuously striking the two sides of the filter cloth 160 to remove dust, thereby increasing the speed of dust removal.

[0058] Specifically, the connecting rod 42 is provided with a third conical tooth 420 at both ends, and a positioning block 18 is provided on the outer wall of the housing 1 at the position corresponding to the connecting rod 42. One of the third conical teeth 420 meshes with the second conical tooth 413, and the other third conical tooth 420 meshes with the first conical tooth 401.

[0059] In this utility model, the connecting rod 42 is rotatably connected to the positioning block 18 to limit the position of the connecting rod 42. With the cooperation of the connecting rod 42 with the third conical tooth 420, the first conical tooth 401 on the output shaft of the motor 40 rotates to drive the second conical tooth 413 to rotate, thereby realizing the synchronous rotation of the crankshaft disk 400 and the rotating rod 41, so as to realize the up and down shaking dust removal of the filter cloth 160 and the side beating dust removal at the same time.

[0060] In this embodiment of the easy-to-clean bag filter, when in use, the box 1 with the guide bucket 10 is first combined with the dust collection box 2 with the drawer 21.
