Description

Technical Field

[0001] This utility model relates to the technical field of pulse jet dust collector blowing device, and in particular to a novel pulse valve blowing pipe device for pulse jet dust collector and its dust collector. Background Technology

[0002] The cement production process includes limestone crushing, clinker calcination, and cement grinding. Dust collectors are required in each production stage. The commonly used dust collector is the air-box pulse dust collector. The electromagnetic pulse valve is connected to the air chamber by a common rubber hose. Due to the requirements of the production process, the compressed air pressure needs to be maintained between 0.45-0.5 MPa to clean the dust accumulated on the surface of the filter bags.

[0003] For example, a novel air-box pulse-type dust collector pulse valve blowpipe device and dust collector, publication number CN215352561U, is used in conjunction with a dust collector. Specifically, it consists of an electromagnetic pulse valve, a union, a high-pressure hose, a hose clamp, an air box, and a blowpipe. The union includes union one and union two. The electromagnetic pulse valve is connected to the top of the high-pressure hose. The middle section of the high-pressure hose is fixed between union one and union two via hose clamps. The end of the high-pressure hose is the blowpipe. The blowpipe is connected to the air box and is horizontally installed to prevent damage to the filter bag edges. A dust collector is also provided with the aforementioned novel air-box pulse-type dust collector pulse valve blowpipe device, a cylinder, an air tank, a discharge device, and several filter bag chambers. The compressed air used in the cylinder is provided by the air tank, and the material collected in the filter bag chambers is discharged by the discharge device.

[0004] However, the filter bag is installed at the air outlet of the air box. Therefore, the compressed air blown out through the nozzle will generate a large wind speed at the air outlet of the air box. The resulting airflow and wind speed can still easily cause damage to the edges of the filter bag. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the pulse jet cleaning device in the existing air box pulse dust collector, and to propose a new air box pulse dust collector pulse valve cleaning pipe device and its dust collector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel air-box pulse-type dust collection pulse valve blowpipe device and its dust collector. The blowpipe device includes an air box, and the dust collector includes several filter cylinders. The filter cylinders are grouped in pairs and a distribution pipe is provided between them and the air outlet of the air box. The bottom of the distribution pipe is provided with two air outlets, which are respectively inserted into the openings of two filter cylinders. Two suspended seats are symmetrically and movably installed on the bottom side of the outer side of the distribution pipe. A spring is provided between the upper surface of the suspended seat and the outer wall of the distribution pipe, and a motor is fixedly installed on the side of the suspended seat. An electric telescopic rod is fixedly installed on the main shaft of the motor. There are two electric telescopic rods on the distribution pipe, which are respectively set on both sides of two filter cylinders on the distribution pipe. The telescopic ends of the electric telescopic rods are detachably installed on the outer wall of the adjacent filter cylinders, and the electric telescopic rods extend and retract along the center line of the filter cylinders.

[0007] Preferably, two electric push rods are symmetrically fixedly installed on the bottom edge of the outer wall of the distribution pipe with respect to any of the suspended seats. The telescopic end of the electric push rod is provided with a locking block that is inserted into the outer wall of the distribution pipe and used to engage with the top plate of the suspended seat.

[0008] Preferably, a vibration motor is provided at the bottom of the outer cylinder of the filter cartridge.

[0009] Preferably, the distribution pipe is fixedly installed with a coaxially arranged partition plate, and a ventilation pipe is provided between the surface of the partition plate and the two air outlets at the bottom of the distribution pipe. Along the airflow direction, the air inlet end of the ventilation pipe is inserted through the surface of the partition plate.

[0010] Preferably, a turntable is rotatably connected through the center of the upper surface of the partition plate, and two symmetrically arranged first through holes are opened on the surface of the turntable, and a second through hole is opened near the position of the first through hole.

[0011] Preferably, the two first through holes are used to control the simultaneous opening of the air inlets of the two ventilation pipes in the distribution pipe, and the second through hole is used to control the opening of one of the air inlets of the ventilation pipe.

[0012] Preferably, a lower bevel gear is fixedly installed at the center of the turntable surface, extending downward through the partition plate. A double-headed bevel gear shaft is rotatably connected through the side wall of the distribution pipe. Both ends of the double-headed bevel gear shaft are bevel gear-shaped, with one end meshing with the lower bevel gear and the other end extending outside the distribution pipe. A drive bevel gear is rotatably connected to the outside of the distribution pipe, meshing with the bevel gear-shaped shaft at the other end of the double-headed bevel gear shaft. A through strip rotatably connected to the outer wall of the distribution pipe is provided between several drive bevel gears.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a distribution pipe and a filter cylinder, the air in the air box is filtered by the two filter cylinders connected to its bottom end through the distribution pipe. Because the distribution pipe and filter cylinder are made of rigid materials, their strength and durability are greater than those of the filter bag. Therefore, the large wind speed and airflow generated at the air box outlet will not cause edge damage.

[0015] 2. In this utility model, by setting a turntable, the second through hole and two first through holes opened on the surface of the turntable are used to adjust the relative position of the second through hole and the first through hole with the rotation of the turntable, so as to facilitate the simultaneous use, alternating use or simultaneous closure of the two filter cartridges on the distribution pipe.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-5 As shown, a novel air-box pulse-type dust collection pulse valve blowpipe device and its dust collector are disclosed. The blowpipe device includes an air box 1. The other structures on the surface of the air box 1 refer to the relevant structures on the surface of the "air box" in the novel air-box pulse-type dust collection pulse valve blowpipe device and dust collector disclosed in the background art, with the publication number CN215352561U. The dust collector includes several filter cartridges 6, which are arranged in pairs and connected to the air outlet of the air box 1 by a distribution pipe 2. Both the filter cartridges 6 and the distribution pipe 2 are made of rigid materials to ensure the strength of the connection surface and prevent damage due to wind speed. The bottom of the distribution pipe 2 has two air outlets that are respectively inserted into the openings of two filter cartridges 6. Two suspended seats 10 are symmetrically and movably installed on the bottom side of the outer side of the distribution pipe 2. A spring 11 is provided between the upper surface of the suspended seat 10 and the outer wall of the distribution pipe 2, and the side of the suspended seat 10 is also provided with a spring 11. A motor 12 is fixedly installed on one part of the filter cylinder 6. An electric telescopic rod 13 is fixedly installed on the main shaft of the motor 12. There are two electric telescopic rods 13 on the distribution pipe 2, which are respectively set on both sides of the two filter cylinders 6 on the distribution pipe 2. The telescopic ends of the electric telescopic rods 13 are detachably installed on the outer side wall of the adjacent filter cylinder 6, and the electric telescopic rods 13 extend and retract along the center line of the filter cylinder 6. A vibration motor 14 is set at the bottom of the outer cylinder of the filter cylinder 6. When it is necessary to collect the dust filtered in the filter cylinder 6, the electric telescopic rod 13 is extended to make the filter cylinder 6 descend and detach from the distribution pipe 2. Then, the motor 12 drives the electric telescopic rod 13 and the corresponding filter cylinder 6 to rotate 180 degrees so that the opening of the filter cylinder 6 faces downward. Then, the vibration motor 14 is started, and under the condition of the movable connection of the spring 11, the filter cylinder 6 vibrates relative to the distribution pipe 2, which can shake off the residual dust in the filter cylinder 6.

[0025] Furthermore: Two electric push rods 8 are symmetrically fixedly installed on the bottom edge of the outer wall of the distribution pipe 2 with respect to any of the suspended seats 10. The telescopic end of the electric push rod 8 is provided with a locking block 9 that is inserted into the outer wall of the distribution pipe 2 and used to lock into the top plate of the suspended seat 10. In order to prevent the filter cylinder 6 from detaching from the bottom end of the distribution pipe 2 due to wind, the locking block 9 is locked into the side of the suspended seat 10 by extending the electric push rod 8. By using the insertion of the locking block 9 into the side of the distribution pipe 2, the relative position of the suspended seat 10 and the distribution pipe 2 can be fixed, thereby fixing the relative position of the filter cylinder 6 and the distribution pipe 2.

[0026] Furthermore: A coaxially arranged partition plate 18 is fixedly installed on the distribution pipe 2. Ventilation pipes 19 are provided between the surface of the partition plate 18 and the two air outlets at the bottom of the distribution pipe 2. Along the airflow direction, the air inlet end of the ventilation pipe 19 is inserted through and connected to the surface of the partition plate 18. A turntable 7 is rotatably connected through the center of the upper surface of the partition plate 18. Two symmetrically arranged first through holes 16 are opened on the surface of the turntable 7, and a second through hole 17 is opened near one of the first through holes 16. The two first through holes 16 are used to control the simultaneous opening of the air inlets of the two ventilation pipes 19 in the distribution pipe 2, and the second through hole 17 is used to control the opening of the air inlet of one of the ventilation pipes 19. In this scheme, the two filter cartridges 6 can be used alternately, simultaneously, or not at all. When used alternately, the turntable 7 rotates to align the second through hole 17 with the air inlet of one of the ventilation pipes 19, while the area on the turntable 7 opposite the second through hole 17 is closed, thus the air inlet of the other ventilation pipe 19 is closed and not ventilated. When used simultaneously, the turntable 7 is rotated to align the two first through holes 16 with the air inlets of the two ventilation pipes 19 respectively. When not used simultaneously, the turntable 7 is rotated to cover the air inlets of the two ventilation pipes 19 with the closed area on its surface, thus allowing both filter cartridges 6 to be unused at the same time.

[0027] Furthermore: A lower bevel gear 15 extends downward through the partition 18 at the center of the surface of the turntable 7 and is fixedly installed thereon. A double-headed bevel gear shaft 5 is rotatably connected through the side wall of the distribution pipe 2. Both ends of the double-headed bevel gear shaft 5 are bevel gear-shaped, with one end of the bevel gear-shaped shaft meshing with the lower bevel gear 15 and the other end of the bevel gear-shaped shaft extending to the outside of the distribution pipe 2. A drive bevel gear 4 is rotatably connected to the outside of the distribution pipe 2 and meshes with the bevel gear-shaped shaft 5 at the other end. A through strip 3 rotatably connected to the outer wall of the distribution pipe 2 is provided between several drive bevel gears 4. A motor 12 is additionally installed on one of the distribution pipes 2 on both sides to drive the through strip 3 to rotate. The rotation of the through strip 3 relative to the distribution pipe 2 drives the drive bevel gear 4 to rotate. Under the meshing transmission of the double-headed bevel gear shaft 5, the lower bevel gear 15 drives the turntable 7 to rotate, so that all the turntables 7 installed on the air box 1 can rotate simultaneously.

[0028] The working principle is as follows: the electric push rod 8 extends to lock the side of the suspension seat 10 with the locking block 9. By inserting the locking block 9 into the side of the distribution pipe 2, the relative position of the suspension seat 10 and the distribution pipe 2 can be fixed, thereby fixing the relative position of the filter cylinder 6 and the distribution pipe 2. The air in the air box 1 enters the two filter cylinders 6 below along several distribution pipes 2, is filtered, and then is discharged. Then the turntable 7 rotates to close the air inlet of the ventilation pipe 19. The locking block 9 rotates and disengages from the suspension seat 10. The electric telescopic rod 13 extends to lower the filter cylinder 6 and disengage from the distribution pipe 2. Then the electric telescopic rod 13 rotates to rotate the filter cylinder 6 connected to it by 180 degrees so that the opening of the filter cylinder 6 faces downward. Then the vibration motor 14 starts, and under the condition of the movable connection of the spring 11, the filter cylinder 6 vibrates relative to the distribution pipe 2, thereby shaking off the residual dust in the filter cylinder 6.

[0029] The wiring diagrams of the electric push rod 8, motor 12, electric telescopic rod 13 and vibration motor 14 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the electric push rod 8, motor 12, electric telescopic rod 13 and vibration motor 14 will not be explained in detail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
