Description

Technical Field

[0001] This utility model belongs to the field of cement production technology, specifically an automatic dust removal mechanism for filter bags in cement production dust collectors. Background Technology

[0002] In modern cement production processes, key steps such as high-temperature calcination in cement kilns, high-intensity crushing of raw materials in crushers, and fine grinding in ball mills all generate large amounts of high-concentration, highly abrasive industrial dust. To effectively control this process dust, baghouse dust collection technology, with its high-efficiency filtration performance, has been widely used in the cement industry. In a baghouse dust collection system, the filter bags bear the core filtration task; however, as the filtration process continues, dust accumulates on the surface of the filter bags, which not only increases system resistance but may also reduce dust collection efficiency. Therefore, dust removal becomes a crucial step in ensuring the stable and efficient operation of baghouse dust collection systems.

[0003] Meanwhile, the patent specification with application number CN119386563A discloses a self-cleaning component and method for dust removal filter bags in cement mills. "The bottom end of the first shaft of the first telescopic device is connected to a multi-faceted mounting block. Each mounting surface of the multi-faceted mounting block is provided with a fixed sleeve containing an open mounting cavity and a guide groove. A tension spring is inside the open mounting cavity. A movable insert is placed at the open mounting cavity and the guide groove and protrudes outward. A C-shaped magnetic suction piece is fixed to the side end of the movable insert. The bottom end of the second shaft of the second telescopic device is connected to an annular jet component. The upper and lower ends of the annular jet component are also fixed with electromagnetic rings that cooperate with the magnetic suction part. The annular jet component has multiple horizontal air outlet pipes surrounding the dust removal filter bag. The air outlets face the filter bag and are connected to the air supply pipeline. The air supply pipeline is connected to the air supply mechanism." Existing dust collector filter bag cleaning devices in cement production often require manual assistance during use. Mechanical cleaning often involves simple actions and is difficult to automate, resulting in low cleaning efficiency and high labor intensity.

[0004] Therefore, an automatic dust removal mechanism for filter bags in cement production dust collectors is proposed to address the above issues. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an automatic dust removal mechanism for filter bags in cement production dust collectors. It has the advantages of automatic dust removal without manual operation, significantly improving the automation level and work efficiency of dust removal, and the falling dust can automatically slide down and be discharged along the inclined tube sheet, thus cleaning the dust inside the filter bags and further improving the thoroughness and convenience of dust removal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic dust removal mechanism for filter bags in a cement production dust collector, comprising a dust collection chamber, an air outlet fixedly connected to the top of the dust collection chamber, an air inlet fixedly connected to the bottom of the dust collection chamber, a tube sheet slidably connected to the inner surface of the dust collection chamber, a mounting frame fixedly connected to the bottom of the tube sheet 1, a tube sheet 2 mounted on the bottom of the mounting frame via a hinge, a plurality of filter cages mounted on the inner surface of the tube sheet 1, filter bag bodies fixedly fitted onto the outer surfaces of the plurality of filter cages, a plurality of filter screens fixedly connected to the inner surface of the tube sheet 2, and dust removal components mounted on both inner walls of the dust collection chamber, with the two dust removal components being mirror-distributed.

[0007] Preferably, the outer surfaces of several filter cages that come into contact with the inner surface of the tube sheet are provided with a sealing coating.

[0008] Preferably, each of the filter bag bodies is a hollow tubular shape.

[0009] Preferably, a plurality of filter bag bodies and a plurality of filter screens are arranged coaxially in one-to-one correspondence, and the filter screens and filter bag bodies are made of the same material.

[0010] Preferably, two extension plates are fixedly connected to both ends of the second flower plate, and electric telescopic rods are rotatably connected to both ends of the mounting frame via mounting seats. The two electric telescopic rods are rotatably connected to the two extension plates respectively.

[0011] Preferably, the dust removal assembly includes a power motor, which is fixedly connected to one end of the dust collection bin. The output end of the power motor passes through the dust collection bin and is fixedly connected to an eccentric wheel. One end of the eccentric wheel is rotatably connected to a connecting rod, and one end of the connecting rod is rotatably connected to a mounting frame.

[0012] Preferably, two guide blocks are fixedly connected to both ends of the tube sheet, and guide grooves are provided on both inner walls of the dust collection bin to cooperate with the guide blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a dust removal assembly consisting of a power motor, an eccentric wheel, and a connecting rod, drives the mounting frame and filter bag body to reciprocate under the drive of the motor, which can complete automatic dust removal without manual operation, significantly improving the automation level and work efficiency of dust removal.

[0014] 2. This utility model uses an electric telescopic rod to tilt the second tube sheet. The tilt angle creates a guiding slope inside the filter bag, allowing the fallen dust to slide down and be discharged automatically along the tilted tube sheet, thus cleaning the dust inside the filter bag and further improving the thoroughness and convenience of dust removal.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides an automatic dust removal mechanism for filter bags in a cement production dust collector, including a dust collection chamber 1. An air outlet 2 is fixedly connected to the top of the dust collection chamber 1, and an air inlet 3 is fixedly connected to the bottom of the dust collection chamber 1. A tube sheet 11 is slidably connected to the inner surface of the dust collection chamber 1. A mounting frame 12 is fixedly connected to the bottom of the tube sheet 11. A tube sheet 13 is hinged to the bottom of the mounting frame 12. Several filter cages 112 are installed on the inner surface of the tube sheet 11, and filter bag bodies 111 are fixedly fitted onto the outer surfaces of each filter cage 112. Several filter screens 113 are fixedly connected to the inner surface of the tube sheet 13. Dust removal components 15 are installed on both inner walls of the dust collection chamber 1. The two dust removal components 15 are mirror-distributed. Through the combined structure of the tube sheet 11, mounting frame 12, and tube sheet 13 within the dust collection chamber 1, and the mirror-distributed dust removal components 15, an integrated dust removal unit is formed, providing a structural foundation for subsequent efficient dust removal.

[0019] Specifically, the outer surfaces of several filter cages 112 that come into contact with the inner surface of the tube sheet 13 are all provided with a sealing coating. The sealing coating at the contact point between the filter cages 112 and the tube sheet 13 can enhance the sealing of the connection between the two, prevent dust-laden gas from leaking out of the gaps, and ensure the integrity of the filtration path.

[0020] like Figures 1 to 4 As shown, several filter bag bodies 111 are all hollow tubular. The hollow tubular filter bag bodies 111 increase the contact area with the dust-laden gas, improve the filtration efficiency, and at the same time provide a channel space for the internal dust to fall off.

[0021] Furthermore, several filter bag bodies 111 and several filter screens 113 are arranged in a one-to-one correspondence and coaxially. The filter screens 113 and the filter bag bodies 111 are made of the same material to ensure smooth airflow and maintain consistent filtration accuracy, thereby reducing filtration resistance.

[0022] like Figures 1 to 4 As shown, two extension plates 122 are fixedly connected to both ends of the tube sheet 13. Both ends of the mounting bracket 12 are rotatably connected to electric telescopic rods 121 via mounting seats. The two electric telescopic rods 121 are rotatably connected to the two extension plates 122 respectively. The electric telescopic rods 121 drive the tube sheet 13 to rotate through the extension plates 122, which can flexibly adjust the tilt angle of the tube sheet 13 and facilitate control of the dust falling direction.

[0023] It is worth noting that the dust removal assembly 15 includes a power motor 152, which is fixedly connected to one end of the dust collection chamber 1. The output end of the power motor 152 passes through the dust collection chamber 1 and is fixedly connected to an eccentric wheel 151. One end of the eccentric wheel 151 is rotatably connected to a connecting rod 153, and one end of the connecting rod 153 is rotatably connected to the mounting frame 12. The power motor 152 drives the mounting frame 12 to reciprocate through the eccentric wheel 151 and the connecting rod 153, providing stable vibration power for the filter bag body 111 and realizing automatic dust removal.

[0024] like Figures 1 to 4 As shown, two guide blocks 141 are fixedly connected to both ends of the tube sheet 11. Guide grooves 14 are provided on both sides of the inner wall of the dust collection chamber 1 to cooperate with the guide blocks 141. The cooperation between the guide blocks 141 and the guide grooves 14 plays a precise guiding role in the sliding of the tube sheet 11, avoiding movement deviation and ensuring the operational stability of the dust removal assembly 15.

[0025] The power motor 152 and the electric telescopic rod 121 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0026] Working principle and process: Dust-laden gas enters the dust collection chamber 1 through the air inlet 3, and after being filtered by the filter bag body 111 and the filter screen 113, the clean gas is discharged from the air outlet 2. During dust removal, the power motor 152 drives the eccentric wheel 151 and the connecting rod 153 to drive the mounting frame 12 and the tube sheet 11 and tube sheet 2 to vibrate back and forth. At the same time, the electric telescopic rod 121 adjusts the tilt angle of the tube sheet 2 13, so that the dust inside and outside the filter bag body 111 falls off under the action of vibration and gravity and is discharged along the tilted tube sheet 2 13, thus realizing automatic dust removal.
