Description

Technical Field

[0001] This utility model relates to the field of dust removal and filtration technology, specifically a vibration state monitoring and anti-clogging dust removal and filtration device. Background Technology

[0002] Industrial dust removal technology is an indispensable part of environmental protection and safety assurance in modern industrial production, widely used in many industries such as power, metallurgy, chemical, building materials, and food processing. With increasingly stringent environmental regulations and higher production process requirements, efficient, stable, and low-consumption dust removal systems have become an important component of industrial equipment. Traditional dust removal devices mostly adopt technologies such as bag filtration, electrostatic sedimentation, and wet dust collection. Among these, bag filters have become one of the most widely used dust removal devices due to their simple structure, strong adaptability, and high dust removal efficiency. This type of equipment typically uses fiber filter media to capture particulate matter in dust-laden gas, achieving efficient separation of the gas-solid two-phase flow.

[0003] Currently, common dust removal and cleaning methods mainly include mechanical vibration, reverse air blowing, and pulse jet cleaning. Mechanical vibration cleaning relies on periodic vibration of the filter bag to remove attached dust, but its cleaning intensity is limited and it is prone to filter bag fatigue damage. Reverse air blowing uses reverse airflow to deform the filter bag and shake off dust, but it has high energy consumption and poor cleaning effect on fine dust. Pulse jet cleaning uses compressed air to blow into the inside of the filter bag instantaneously, generating a strong reverse airflow to achieve cleaning. Although the cleaning effect is better, it still has problems such as uneven cleaning, easy damage to the filter bag opening, and high energy consumption. Especially when dealing with high humidity, high viscosity, or ultrafine dust, it not only increases the system operating resistance and the fan load, but also significantly shortens the filter bag life.

[0004] In addition, existing dust removal control methods mostly adopt timed or differential pressure methods, which lack real-time perception and feedback of the actual status of the filter bags, making it difficult to achieve dynamic matching between the dust removal process and the clogging status, thus resulting in energy waste or insufficient dust removal.

[0005] Therefore, in order to address the above problems, the applicant needs to design a vibration state monitoring anti-clogging dust removal and filtration device to solve the problem. Utility Model Content

[0016] Furthermore, the vibrator is a high-frequency electromagnetic vibrator, and is connected to an external controller via a wire. The controller is used to receive signals from the vibration sensor and control the start / stop and vibration intensity of the vibrator.

[0017] Through the above structural design, the vibrator and controller can work together to intelligently adjust the cleaning intensity according to the actual blockage state.

[0025] 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.

[0026] like Figures 1-5 As shown, this utility model discloses a vibration state monitoring anti-clogging dust removal and filtration device, including a support frame 1, on which a filter chamber 10 is provided. A perforated plate 17 is fixedly provided on the inner side of the filter chamber 10 in a horizontal reverse direction, and a dust removal filter bag assembly 2 is correspondingly provided below the perforated plate 17. The dust removal filter bag assembly 2 includes a fixed hopper 20, and a three-layer composite filter bag body 21 is provided below the fixed hopper 20. A connecting rod 23 is fixedly provided on the inner side of the filter bag body 21, and a suspension frame 22 is provided on the connecting rod 23. The fixed hopper 20 is set on the perforated plate 17 through the suspension frame 22. An installation plate 24 is fixedly provided on the fixed hopper 20, and an installation seat 25 is fixedly provided on the installation plate 24. A vibrator 26 is provided on the installation seat 25, and the vibrator 26 is used to drive the fixed hopper 20 to vibrate. A stabilizing seat 27 is fixedly provided on the installation plate 24, and a vibration sensor 28 is provided on the stabilizing seat 27, and the vibration sensor 28 is used to detect the amount of dust accumulation on the filter bag body 21.

[0027] The filter chamber 10 is hinged with a movable door 15, and the movable door 15 is provided with a locking pin 16 for locking the movable door 15 and the filter chamber 10. Through the cooperation of the hinged movable door 15 and the locking pin 16, the opening and closing operation of the filter chamber 10 becomes simple and quick, which facilitates the operator to carry out daily inspection, maintenance and replacement of the internal components, effectively reducing the maintenance cost and time of the equipment.

[0028] An air jet pipe 14 is provided above the perforated plate 17. The air inlet end of the air jet pipe 14 is fixedly connected to a connecting pipe 13, and the air inlet end of the connecting pipe 13 passes through the filter chamber 10 and extends to the outside of the filter chamber 10. The air jet pipe 14 introduces compressed air through the connecting pipe 13, which can spray reverse airflow onto the filter bag body 21. This effectively complements the vibration cleaning method, and together they make the dust layer attached to the filter bag fall off more thoroughly, improving the overall cleaning efficiency and effect.

[0029] The air inlet end of the connecting pipe 13 is fixedly connected to the connector 12, and the air inlet end of the connector 12 is fixedly connected to the buffer air cylinder 11. The buffer air cylinder 11 is fixedly connected to the external air pump. As a pressure-stabilizing air storage device, the buffer air cylinder 11 can store a sufficient amount of compressed air and output air pressure stably, effectively eliminating airflow pulses and ensuring the stability and uniformity of the airflow sprayed by the jet pipe 14, making the dust removal process more stable and reliable.

[0030] The bottom of the filter chamber 10 is designed as a cone shape, and a dust discharge valve 18 is provided at the bottom opening of the cone shape. This allows the dust to be removed to naturally gather and slide down to the dust discharge valve 18 at the bottom under the action of gravity. The dust discharge valve 18 can control the concentration and orderly discharge of dust, avoid dust accumulation at the bottom of the chamber, and ensure the continuous and stable operation of the system.

[0031] The vibrator 26 is a high-frequency electromagnetic vibrator and is connected to an external controller via a wire. The controller is used to receive the signal from the vibration sensor 28 and control the start and stop of the vibrator 26 and the vibration intensity. The vibration sensor 28 monitors the vibration state of the filter bag in real time and feeds the signal back to the controller, which controls the start and stop of the vibrator 26 and the vibration intensity. This achieves the purpose of energy saving and consumption reduction while ensuring the dust removal effect.

[0032] The filter bag body 21 is made of a three-layer composite structure consisting of a surface filter cloth 210, a middle support net 211, and an inner base cloth 212. This three-layer composite structure gives the filter bag higher mechanical strength and overall stability, and extends the service life of the filter bag.

[0033] The surface filter cloth 210, the middle support mesh 211, and the inner base cloth 212 are respectively polypropylene fiber cloth, polyamide woven mesh, and nylon filament woven cloth. Polypropylene fiber has good chemical corrosion resistance, polyamide woven mesh provides excellent impact resistance and support performance, and nylon base cloth has high mechanical strength and wear resistance. The combination of the three enables the filter bag body 21 to adapt to complex working conditions such as high humidity and high corrosion, and exhibits excellent comprehensive performance.

[0034] When using this vibration state monitoring anti-clogging dust removal and filtration device, dust-laden gas enters the filter chamber 10 and passes through the filter bag body 21 for filtration. Clean gas is discharged through the filter bag, while dust is trapped on the outer surface of the filter bag. As dust accumulates, the vibration sensor 28 monitors the vibration state changes of the filter bag in real time and transmits the data to the controller. When the vibration characteristics decay, indicating that the blockage has reached a predetermined threshold, the controller immediately starts the high-frequency electromagnetic vibrator 26 installed on the mounting base 25, which drives the fixed bucket 20 and the filter bag body 21 connected to it to generate high-frequency micro-amplitude vibration, effectively shaking off the attached dust. At the same time, as needed, reverse airflow is injected through the buffer air cylinder 11 and the jet pipe 14 to assist in dust removal. The removed dust falls into the conical bottom of the filter chamber 10 and is finally discharged by the ash discharge valve 18, thus realizing a high-efficiency, low-consumption, and anti-clogging dust removal cycle.

[0035] 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.
