Description

Technical Field

[0001] This utility model relates to a flue gas cyclone dust removal device with a dust removal function, belonging to the technical field of dust removal equipment. Background Technology

[0002] In flue gas treatment processes, after desulfurization and denitrification, the flue gas, carrying dust, enters the cyclone dust collector tangentially under the action of an induced draft fan. The gas spirals downwards along the inner wall of the cylinder, and the dust is thrown towards the side wall of the cylinder by centrifugal force and falls to the bottom of the cylinder under gravity. The purified gas is discharged through the central pipe of the cylinder. The dust thrown towards the side wall adheres to the inner wall of the cylinder. Gravity alone cannot completely remove the dust from the inner wall, thus requiring regular manual cleaning of the cyclone dust collector, which reduces its practicality. Utility Model Content

[0003] The purpose of this utility model is to provide a flue gas cyclone dust collector with a dust removal function. The dust removal component drives the dust collector cylinder to vibrate radially and reciprocally, which can cause the dust adhering to the inner wall of the cylinder to fall off. Then, the dust accumulated in the dust collector cylinder can be discharged through the opening and closing component, which improves the practicality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A flue gas cyclone dust collector with a dust removal function includes a base and a dust collector cylinder. An air inlet pipe tangent to the side wall of the dust collector cylinder is provided on one side of the top of the dust collector cylinder. An air outlet pipe extending into the cylinder body is coaxially provided on the top of the dust collector cylinder. The dust collector cylinder vertically passes through the base, and a dust removal component is provided between the base and the dust collector cylinder. The dust removal component is used to drive the dust collector cylinder to reciprocate radially to dislodge the dust adhering to the inner wall of the dust collector cylinder. An opening and closing component is provided at the bottom outlet of the dust collector cylinder. The opening and closing component is used to open or close the bottom outlet of the dust collector cylinder. A controller is provided on the top of the base. The dust removal component and the opening and closing component are electrically connected to the controller to control the operation of the dust removal component and the opening and closing component.

[0005] Preferably, the dust removal assembly includes a fixed ring fixedly sleeved outside the dust collector cylinder, vertical plates symmetrically arranged at the bottom of both sides of the fixed ring, and sliding grooves symmetrically opened on both sides of the top of the base, with sliders slidably connected in the sliding grooves, and the sliders fixedly connected to the corresponding side vertical plates; a fixed plate parallel to the vertical plate is arranged on the outer side of one of the vertical plates, and a moving rod passing through the fixed plate is horizontally arranged on the vertical plate, with a roller horizontally rotatably installed at the end of the moving rod, and a first spring sleeved on the rod body between the fixed plate and the end of the moving rod; a drive mechanism for driving the slider to move back and forth along the sliding groove is installed on the base located outside the roller.

[0006] Preferably, the drive mechanism includes a first motor with its actuation shaft vertically upward, and a cam that fits against the outer wall of the roller is mounted at the end of the actuation shaft of the first motor.

[0007] Preferably, a second spring is provided in the groove located on the outside of the slider.

[0008] Preferably, the opening and closing assembly includes a fixed base installed on the bottom outlet side of the dust collector, a connecting block rotatably disposed at the bottom of the fixed base, a sealing cover abutting against the opening at the bottom of the dust collector, and the sealing cover being fixedly connected to the connecting block; the fixed base is also provided with a rotating mechanism for driving the sealing cover to close or open the bottom opening of the dust collector.

[0009] Preferably, the rotating mechanism includes a second motor mounted on a fixed base with its actuation shaft vertically downward. A drive gear is mounted on the actuation shaft of the second motor, and a rotating shaft extending above the fixed base is mounted on a connecting block. A driven gear meshing with the drive gear is mounted on the rotating shaft.

[0010] Preferably, a sealing ring is embedded in the bottom surface of the opening at the bottom of the dust collector cylinder.

[0011] The beneficial effects of this utility model are as follows: 1. The cam is driven to rotate by the first motor. The irregular outer ring structure of the cam, in conjunction with the spring, can drive the vertical plate, the fixed ring, and the dust collector to vibrate back and forth along the slide groove during the rotation. This can shake off the dust attached to the inner wall and realize the timed dust cleaning operation of the dust collector, which can greatly improve its practicality. 2. The second motor drives the meshing drive gear and driven gear to rotate, which in turn drives the sealing cover to rotate, thereby opening or closing the bottom opening of the dust collector. When the bottom opening of the dust collector is open, the dust accumulated inside the dust collector can be discharged and collected. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] This embodiment provides a flue gas cyclone dust collector with a dust removal function. See [link to relevant documentation] Figure 1-5 As shown, the system includes a base 1 and a dust collector 2. An inlet pipe 3, tangential to the side wall of the dust collector 2, is located on one side of the top of the dust collector 2. The inlet pipe 3 is connected to the exhaust pipe of an upstream device via a flexible connecting pipe (in practical applications, a flange is installed at the end of the inlet pipe 3, and flanges are installed at both ends of the flexible connecting pipe to connect the flanges at the ends of the exhaust pipes of the upstream device and the flanges at the ends of the inlet pipe 3 of the dust collector 2; the deformation capacity of the flexible connecting pipe meets the vibration requirements of the dust collector 2). An outlet pipe 4, extending into the body of the dust collector 2, is coaxially located at the top of the dust collector 2. The outlet pipe 4 is also connected to the inlet pipe 3 of the downstream device via a flexible connecting pipe. The dust-laden airflow enters the dust collector 2 tangentially through the inlet pipe 3, spiraling downwards along the inner wall of the cylinder. Dust particles are thrown towards the side wall of the cylinder under centrifugal force and fall to the bottom of the cylinder under gravity. The purified gas is discharged through the outlet pipe 4 of the dust collector 2.

[0016] The dust collector cylinder 2 is vertically inserted through the base 1, and a dust removal assembly is provided between the base 1 and the dust collector cylinder 2. The dust removal assembly is used to drive the dust collector cylinder 2 to reciprocate radially so that the dust adhering to the inner wall of the dust collector cylinder 2 is dislodged. The dust removal assembly includes a fixing ring 5 fixedly sleeved on the outside of the dust collector cylinder 2, vertical plates 6 symmetrically arranged on the bottom of both sides of the fixing ring 5, and sliding grooves 7 (T-shaped grooves) symmetrically opened on both sides of the top of the base 1. A slider 8 (T-shaped structure) is slidably connected in the sliding groove 7, and the slider 8 is fixedly connected to the corresponding side vertical plate 6. A fixed plate 9, parallel to the vertical plate 6, is provided on the outer side of one of the vertical plates 6. A moving rod 10, passing through the fixed plate 9, is horizontally provided on the vertical plate 6. A roller 11 is horizontally rotatably mounted at the end of the moving rod 10. A first spring 12 is sleeved on the rod body between the fixed plate 9 and the end of the moving rod 10. A second spring 13 is provided in the slide groove 7 located outside the slider 8. A drive mechanism for driving the slider 8 to move back and forth along the slide groove 7 is installed on the base 1 located outside the roller 11. The drive mechanism includes a first motor 14 with its actuation shaft vertically upward. A cam 15, which fits against the outer wall of the roller 11, is installed at the end of the actuation shaft of the first motor 14.

[0017] When dust removal is required, the first motor 14 is started to drive the cam 15 to rotate. Due to the irregular outer ring structure of the cam 15, the roller 11 and the moving rod 10 will be pushed to move back and forth laterally during the rotation of the cam 15. During the reciprocating movement of the moving rod 10, the first spring 12 and the second spring 13 located on the rear side will repeatedly experience the process of being compressed and released. The vertical plate 6, the fixed ring 5 and the dust collector 2 will also follow the reciprocating lateral displacement and cause the dust collector 2 to vibrate (vibration occurs when the direction of movement is changed), which can shake off the dust attached to the inner wall.

[0018] The bottom outlet of the dust collector 2 is equipped with an opening and closing assembly for opening or closing the bottom outlet of the dust collector 2. The opening and closing assembly includes a fixed base 16 installed on one side of the bottom outlet of the dust collector 2, a connecting block 17 rotatably disposed at the bottom of the fixed base 16, a sealing cover 18 abutting against the bottom opening of the dust collector 2, and the sealing cover 18 is fixedly connected to the connecting block 17. A sealing ring 19 is embedded in the bottom surface of the bottom opening of the dust collector 2 to prevent dust or flue gas from leaking out through the gap between the sealing cover 18 and the bottom opening of the dust collector 2. A rotating mechanism for driving the sealing cover 18 to close or open the bottom opening of the dust collector 2 is also provided on the fixed base 16. The rotating mechanism includes a second motor 20 mounted on a fixed base 16 with its actuation shaft vertically downward. A drive gear 21 is mounted on the actuation shaft of the second motor 20. A rotating shaft 22 extending above the fixed base 16 is mounted on a connecting block 17 (the rotating shaft 22 is rotatably connected to the connecting block 17; the rotating shaft 22 can be inserted through the bearing and interference-fitted with the bearing by setting a bearing inside the connecting block 17). A driven gear 23 meshing with the drive gear 21 is mounted on the rotating shaft 22.

[0019] When ash removal is required, the second motor 20 is started to drive the drive gear 21 to rotate, which in turn drives the driven gear 23 meshing with the drive gear 21 and the rotating shaft 22 to rotate. As the rotating shaft 22 rotates, it drives the connecting block 17 and the sealing cover 18 fixedly connected to the connecting block 17 to rotate, thereby opening the bottom opening of the dust collector 2. The dust accumulated inside the dust collector 2 can then be discharged through the bottom opening. After ash removal is completed, the second motor 20 is started to drive the sealing cover 18 to rotate and close the bottom opening of the dust collector 2. In practical applications, dust removal equipment is usually set up with at least two sets, one active and one standby, so that when one equipment is performing ash removal, the standby equipment can be activated for dust removal.

[0020] Meanwhile, for ease of operation, a controller 24 is also provided on the top of the base 1. The first motor 14 of the dust cleaning component and the second motor 20 of the opening and closing component are electrically connected to the controller 24 to control the operation of the dust cleaning component and the opening and closing component.

[0021] Any content not described in detail in this specification is prior art known to those skilled in the art.

[0022] The above description is only a preferred embodiment of this utility model patent. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model patent, and these improvements and modifications should also be considered within the scope of protection of this utility model patent.
