Description

Technical Field

[0001] This utility model relates to the field of kiln exhaust gas treatment technology, and in particular to a device for separating large particulate impurities in kiln exhaust gas. Background Technology

[0002] During production and use, kilns emit a large amount of particulate exhaust gas containing impurities. Therefore, various equipment is needed to treat the exhaust gas, filter impurities, and purify the exhaust gas. Cyclone dust collectors are one of the commonly used dust removal devices.

[0003] Traditional cyclone dust collectors operate by drawing exhaust gas through a fan into the collector's cylinder via a conveying pipe. The gas rotates downwards within the cylinder, and the rotational inertia generates centrifugal force, separating large particles at the bottom. The filtered gas then passes through a discharge valve into the ash hopper. The filtered gas, due to the cylinder's upward rotation, exits through a discharge pipe. However, in practice, it has been found that as the dust-laden gas rotates downwards within the cylinder, a large amount of sticky dust adheres to the inner wall, causing roughening of the inner wall, interfering with airflow rotation, and weakening centrifugal force. Furthermore, the thickened dust layer effectively reduces the cylinder's effective diameter, altering airflow velocity, reducing the separation of large particles, and impacting the equipment's practicality and efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that when dust-laden gas is conveyed downwards in a cylindrical container, a large amount of sticky dust adheres to the inner wall of the container, causing roughening of the inner wall, interfering with airflow rotation, and weakening centrifugal force. Furthermore, the thickening of the adhered dust layer is equivalent to reducing the effective diameter of the container, changing the airflow velocity, reducing the separation effect of large particles, and affecting the practicality and working efficiency of the equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a kiln exhaust gas large particulate matter separation device, including a cyclone dust collector, the cyclone dust collector is provided with a cylinder, wherein an ash hopper is installed at the bottom of the cylinder, the top of the cyclone dust collector is connected to an exhaust pipe, a conveying pipe is fixedly connected to the surface of the cyclone dust collector, wherein a fan is installed at one end of the conveying pipe, and an auxiliary device is provided on the surface of the cylinder, wherein the auxiliary device uses a striking plate and a spring to strike and vibrate the surface of the cylinder.

[0006] The effect achieved by the above components is as follows: When the cyclone dust collector separates large particulate impurities from the exhaust gas emitted from the kiln, the exhaust gas is first drawn into the cylinder of the cyclone dust collector by the fan and conveyed through the conveying pipe. The exhaust gas rotates downward along the cylinder, and the rotational inertia generates centrifugal force. When it reaches the bottom, the large particulate matter in the gas is separated. Finally, it enters the ash hopper through the discharge valve. The filtered gas rotates upward due to the cylinder structure and is discharged through the exhaust pipe. At the same time, the auxiliary device on the outer surface of the cylinder is activated to generate knocking vibration on the cylinder, shaking off the adhering particles attached to the inner wall of the cylinder and letting them fall into the ash hopper.

[0007] Preferably, the auxiliary device includes a bracket, wherein the bracket is connected and fixed to the arc surface of the cylinder, and a plurality of uniformly circumferentially distributed mounting shafts are fixedly connected to the surface of the bracket, wherein a striking plate is rotatably connected to the arc surface of the mounting shaft, a plurality of protrusions are provided on one side surface of the striking plate, and a spring is fixedly connected to one side of the striking plate, wherein the other end of the spring is connected and fixed to the arc surface of the cylinder, and a rope loop is commonly sleeved on the surface of the plurality of striking plates, wherein a retraction assembly is provided on the surface of the cylinder, wherein the retraction assembly adjusts the retraction state of the rope loop.

[0008] The effect achieved by the above components is that, during use, the cyclone dust collector can actively shake the dust particles adhering to the inner wall to the ash hopper through periodic, low-intensity mechanical impact, avoiding the formation of ash layers and ensuring that the cylinder is always in a "smooth and effective diameter stable" state, thereby maintaining a long-term stable large particle separation efficiency.

[0009] Preferably, the take-up and unwind assembly includes a mounting frame, wherein the mounting frame is fixedly connected to the surface of the cylinder, and a take-up reel is rotatably connected to the inner wall of the mounting frame. The arc surface of the take-up reel is fixedly connected to the rope loop, and a full gear is fixedly connected to one side of the take-up reel. A servo motor is mounted on one side of the mounting frame, and a half gear is assembled at the output end of the servo motor via a coupling.

[0010] The effect achieved by the above components is that the striking plate will rotate in the opposite direction under the tension of the spring when the retraction assembly is activated, until the protrusion on the striking plate contacts and impacts the cylinder.

[0011] Preferably, the auxiliary device further includes a limiting ring installed on one side of the striking plate, wherein the rope loop passes through the inner wall of the limiting ring.

[0012] The effect achieved by the above components is that, by setting the limiting ring, the rope ring can be stably set on one side of the striking plate, and it is not easy for it to slip off, thereby ensuring the stable rotation of the striking plate and the normal use of the device.

[0013] Preferably, a protective shell is fixedly connected to the surface of the mounting bracket, wherein the protective shell covers the surface of the full gear and the half gear.

[0014] The effect achieved by the above components is that, by setting up a protective shell, the half gear and the full gear are not easily exposed to the outside, which can lead to the adhesion of foreign objects and cause the meshing to jam.

[0015] Preferably, a protective ring is fitted and fixed on the arc surface of the cylinder, wherein the protective ring ensures the normal use of the cylinder.

[0016] The effect achieved by the above components is that, through the setting of the protective ring made of sponge material, the protrusions on the striking plate can provide a certain degree of protection at the impact point when impacting the surface of the cylinder, making the cylinder less prone to deformation and damage.

[0017] Preferably, the surface of the striking plate is provided with a groove, wherein a limiting rod is slidably connected to the inner wall of the groove, and the limiting rod is fixedly connected to the arc surface of the cylinder.

[0018] The effect achieved by the above components is that, through the setting of the limiting rod and the sliding groove, the striking plate can better maintain stability during rotation and is less prone to shaking or deviation.

[0019] Preferably, the auxiliary device further includes torsion springs sleeved on the arc surfaces on both sides of the mounting shaft, wherein the two ends of the torsion springs are respectively connected and fixed to the striking plate and the bracket.

[0020] The effect achieved by the above components is as follows: the torsional force provided by the torsion spring to the striking plate allows the striking plate to rotate more quickly under the combined force of the spring and the torsion spring when the rope loop is loosened, thus making the striking vibration of the striking plate on the cylinder more efficient and intense.

[0021] The beneficial effects of this utility model are:

[0022] When in use, the cyclone dust collector of this utility model can actively shake off the dust particles adhering to the inner wall into the ash hopper through periodic, low-intensity mechanical knocking, avoiding the formation of ash layer and ensuring that the cylinder is always in a "smooth and effective diameter stable" state, thereby maintaining a long-term stable large particle separation efficiency.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Figure 1 and Figure 2 The device shown is a kiln exhaust gas large particulate matter separation device, including a cyclone dust collector 1. The cyclone dust collector 1 is provided with a cylinder 4, wherein an ash hopper 5 is installed at the bottom of the cylinder 4, and an exhaust pipe 6 is connected to the top of the cyclone dust collector 1. A conveying pipe 7 is fixedly connected to the surface of the cyclone dust collector 1, wherein a fan 8 is installed at one end of the conveying pipe 7. An auxiliary device 2 is provided on the surface of the cylinder 4, wherein the auxiliary device 2 uses a striking plate 23 and a spring 25 to strike and vibrate the surface of the cylinder 4. A take-up and release assembly 3 is provided on the surface of the cylinder 4, wherein the take-up and release assembly 3 adjusts the retraction state of the rope ring 26.

[0034] Figure 1 - Figure 4As shown, when the cyclone dust collector 1 separates large particulate impurities from the exhaust gas emitted from the kiln, the exhaust gas is first drawn into the cylinder 4 of the cyclone dust collector 1 by the fan 8 through the conveying pipe 7. The exhaust gas rotates downwards along the cylinder 4, and the rotational inertia generates centrifugal force. Upon reaching the bottom, the large particles in the gas are separated and finally enter the ash hopper 5 through the discharge valve. The filtered gas rotates upwards due to the structure of the cylinder 4 and is discharged through the exhaust pipe 6. Simultaneously, the receiving and releasing assembly 3 on the outer surface of the cylinder 4 is activated, causing the striking plate 23 to rotate on the arc surface of the mounting shaft 22 of the support 21. This causes one end of the protrusion 24 to disengage from the cylinder 4 and move away. When the half-tooth... When wheel 34 disengages from gear 35, winding reel 32 rotates and rope loop 26 loosens. At this time, striking plate 23 rotates in the opposite direction under the tension of spring 25 until several protrusions 24 on striking plate 23 contact and impact cylinder 4, generating knocking vibration on cylinder 4, shaking off the adhering particles attached to the inner wall of cylinder 4 and letting them fall into ash hopper 5. When the cyclone dust collector 1 is in use, it can actively shake off the dust particles adhering to the inner wall to ash hopper 5 through periodic, low-intensity mechanical knocking, avoiding the formation of ash layer and ensuring that cylinder 4 is always in a "smooth and effective diameter stable" state, thereby maintaining long-term stable large particle separation efficiency.

[0035] Figure 2 and Figure 6 The shown take-up and unwind assembly 3 includes a mounting frame 31, which is fixedly connected to the surface of the cylinder 4. A take-up reel 32 is rotatably connected to the inner wall of the mounting frame 31. The arc surface of the take-up reel 32 is fixedly connected to the rope loop 26. A full gear 35 is fixedly connected to one side of the take-up reel 32. A servo motor 33 is mounted on one side of the mounting frame 31. The output end of the servo motor 33 is equipped with a half gear 34 via a coupling. When controlling the tightening and loosening of the rope loop 26, the servo motor 33 on the mounting frame 31 is started first. The start of the servo motor 33 will drive the rotation of the half gear 34. During rotation, wheel 34 engages with the full gear 35 on one side of the take-up reel 32. Then, the take-up reel 32 winds up and contracts the rope loop 26. At this time, the tightened rope loop 26 presses the striking plate 23 close to the spring 25, causing the striking plate 23 to rotate on the mounting shaft 22. This causes one end of the protrusion 24 to disengage from the cylinder 4 and move away. When the half gear 34 disengages from the full gear 35, the take-up reel 32 rotates back and loosens the rope loop 26. At this time, the striking plate 23 rotates in the opposite direction under the tension of the spring 25 until the protrusion 24 on the striking plate 23 contacts and impacts the cylinder 4.

[0036] Figure 3 and Figure 6The auxiliary device 2 shown also includes a limiting ring 211 installed on one side of the striking plate 23, wherein the rope loop 26 passes through the inner wall of the limiting ring 211. The setting of the limiting ring 211 allows the rope loop 26 to be stably set on one side of the striking plate 23, making it less likely to slip and detach, thereby ensuring the stable rotation of the striking plate 23 and the normal use of the device. A protective shell 36 is fixedly connected to the surface of the mounting bracket 31, wherein the protective shell 36 covers the surface of the full gear 35 and the half gear 34. The setting of the protective shell 36 makes it difficult for the half gear 34 and the full gear 35 to be exposed, resulting in the adhesion of foreign objects and causing the meshing to jam.

[0037] Figure 3 and Figure 4 A protective ring 27 is fixedly fitted onto the arc surface of the cylindrical body 4. The protective ring 27 ensures the normal use of the cylindrical body 4. With the setting of the protective ring 27 made of sponge material, the protrusion 24 on the striking plate 23 can protect the impact position when it hits the surface of the cylindrical body 4, so that the cylindrical body 4 is not easily deformed and damaged. The surface of the striking plate 23 is provided with a sliding groove 28, and the inner wall of the sliding groove 28 is slidably connected to a limit rod 29. The limit rod 29 is connected and fixed to the arc surface of the cylindrical body 4. With the setting of the limit rod 29 and the sliding groove 28, the striking plate 23 can better maintain stability during rotation and is not easy to shake or deviate.

[0038] Figure 4 and Figure 5 The auxiliary device 2 shown also includes torsion springs 210 sleeved on the arc surfaces on both sides of the mounting shaft 22. The two ends of the torsion springs 210 are respectively connected and fixed to the striking plate 23 and the bracket 21. The torsional force given to the striking plate 23 by the torsion springs 210 causes the striking plate 23 to rotate more quickly under the combined force of the spring 25 and the torsion springs 210 when the rope ring 26 is relaxed. This makes the striking vibration of the striking plate 23 on the cylinder 4 more efficient and intense.

[0039] Working principle: When the cyclone dust collector 1 separates large particulate impurities from the exhaust gas emitted from the kiln, the exhaust gas is first drawn into the cylinder 4 of the cyclone dust collector 1 by the fan 8 through the conveying pipe 7. The exhaust gas rotates downward along the cylinder 4, and the rotational inertia generates centrifugal force. When it reaches the bottom, the large particles in the gas are separated and finally enter the ash hopper 5 through the discharge valve. The filtered gas rotates upward due to the structure of the cylinder 4 and is discharged through the exhaust pipe 6. At the same time, the receiving and releasing assembly 3 on the outer surface of the cylinder 4 is activated, causing the striking plate 23 to rotate on the arc surface of the mounting shaft 22 of the support 21, causing one end of the protrusion 24 to disengage from the cylinder 4 and move away. When half When gear 34 disengages from gear 35, winding reel 32 rotates and rope loop 26 loosens. At this time, striking plate 23 rotates in the opposite direction under the tension of spring 25 until several protrusions 24 on striking plate 23 contact and impact cylinder 4, generating knocking vibration on cylinder 4, shaking off the adhering particles attached to the inner wall of cylinder 4 and letting them fall into ash hopper 5. When the cyclone dust collector 1 is in use, it can actively shake off the dust particles adhering to the inner wall to ash hopper 5 through periodic, low-intensity mechanical knocking, avoiding the formation of ash layer and ensuring that cylinder 4 is always in a "smooth and effective diameter stable" state, thereby maintaining long-term stable large particle separation efficiency.

[0040] When controlling the tightening and loosening of the rope loop 26, the servo motor 33 (model Estun EM3A series) on the mounting bracket 31 is first started. The start of the servo motor 33 will drive the rotation of the half gear 34. During the rotation, the half gear 34 will mesh with the full gear 35 on one side of the take-up reel 32. Then the take-up reel 32 will wind up and tighten the rope loop 26. At this time, the tightened rope loop 26 will press the striking plate 23 close to the spring 25, so that the striking plate 23 will rotate on the mounting shaft 22, causing one end of the protrusion 24 to disengage from the cylinder 4 and move away. When the half gear 34 disengages from the full gear 35, the take-up reel 32 will rotate back and loosen the rope loop 26. At this time, the striking plate 23 will rotate in the opposite direction under the tension of the spring 25 until the protrusion 24 on the striking plate 23 contacts and impacts the cylinder 4.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
