Abstract
Description
Technical Field
[0001] This utility model relates to the field of pigment dust collection technology, specifically a pigment dust collection device. Background Technology
[0002] During the production, processing and use of pigments, a large amount of pigment dust is generated that is suspended in the air. This dust contains not only chemical substances such as titanium dioxide and azo dyes, but also causes air pollution if it is directly emitted into the environment.
[0003] Existing devices mostly employ single-stage filter filtration or single electrostatic adsorption methods. If relying solely on filter filtration, large-diameter dust particles easily clog the filter pores, leading to increased wind resistance, a rapid decline in filtration efficiency, and frequent filter replacements. If relying solely on electrostatic adsorption, large-diameter dust particles in the dust-laden airflow directly impact the axial fan blades and anode plate surface, causing blade wear and anode plate deformation. This not only shortens the service life of core components but also causes instability in the electrostatic field due to component wear, thereby reducing the adsorption efficiency for fine dust. Ultimately, this results in excessive dust residue in the exhaust gas, failing to meet environmental emission requirements. Therefore, a pigment dust collection device is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a pigment dust collection device, which solves the problem of inconvenient pigment dust collection.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a pigment dust collection device, comprising a filter box, wherein an exhaust pipe is fixedly connected to the right surface of the filter box, and a first filter screen is fixedly connected to the inner wall of the exhaust pipe; The filter box is equipped with a dust collection mechanism, which includes an air inlet pipe, a PLC control box, a battery, a first filter, a second filter, a dustproof shell, a motor, and an axial fan. The air inlet pipe is fixedly connected to the left surface of the filter box, and the second filter screen is fixedly connected to the inner wall of the air inlet pipe.
[0006] Preferably, the dustproof housing is fixedly installed in the inner wall of the filter box, the motor is fixedly connected to the inner surface of the dustproof housing, and the output shaft of the motor extends through the left surface of the dustproof housing; The axial fan is fixedly connected to the output end of the motor.
[0007] Preferably, the PLC control box is fixedly connected to the front surface of the filter box, the battery is fixedly connected to the upper surface of the filter box, and the battery is electrically connected to the PLC control box.
[0008] Preferably, the dust collection mechanism further includes an anode plate, sliding rollers, and springs. Multiple sliding rollers are slidably sleeved in the inner wall of the top plate of the filter box, and multiple anode plates are respectively fixedly installed at the lower ends of multiple sliding rollers. Multiple anode plates are electrically connected to the PLC control box. Multiple springs are fixedly connected to the upper surface of multiple anode plates, and the upper ends of multiple springs are fixedly connected to the lower surface of the top plate of the filter box.
[0009] Preferably, the dust collection mechanism further includes a dust collection hopper, a fixed frame, and a vibration motor, wherein the fixed frame is fixedly connected to the outer surface of the anode plate, and the vibration motor is fixedly connected to the outer surface of the fixed frame; The dust collection hopper is fixedly connected to the upper surface of the bottom plate of the filter box, and the dust collection hopper is installed correspondingly to the anode plate.
[0010] Compared with the prior art, the present invention provides a pigment dust collection device, which has the following beneficial effects: 1. This pigment dust collection device uses a second filter to intercept large-particle dust, reducing wear on the axial fan and anode plate and extending component life. The anode plate uses an electrostatic field to adsorb fine particles, achieving efficient separation. The first filter finally intercepts residual dust, ensuring that the exhaust gas meets standards. The three-stage process is progressive, which not only improves purification accuracy but also reduces wear on core components, taking into account both environmental protection and equipment durability.
[0011] 2. In this pigment dust collection device, the vibrating motor transmits the vibration force to the anode plate through the fixed frame. The sliding roller allows the anode plate to vibrate slightly up and down, and the spring provides elastic support and reset buffer. The three work together to make the adsorbed dust fall into the dust collection hopper efficiently, eliminating the need for frequent manual cleaning. At the same time, the spring buffers the vibration impact, and the sliding roller limits the vibration range to avoid component collisions and ensure long-term stable operation and maintenance of the device.

The dust collection hopper 11 is fixedly connected to the upper surface of the bottom plate of the filter box 1, and the dust collection hopper 11 is installed in a corresponding manner with the anode plate 12.
[0020] Structural Explanation: Filter Box 1: As the core carrier of the device, it provides the installation reference and housing space for all components such as the air inlet pipe 2 and the air outlet pipe 3, constructs a closed dust treatment cavity, ensures that the airflow flows along the preset path, avoids leakage of dust-laden airflow, and is the basic framework for the coordinated work of all modules.
[0021] Air inlet duct 2: Fixed to the left surface of filter box 1, it is the inlet channel for airflow containing pigment dust. It can guide the airflow into the interior of filter box 1. At the same time, the second filter screen 7 fixed on its inner wall can perform preliminary filtration of the airflow, laying the foundation for subsequent treatment.
[0022] Exhaust duct 3: Installed on the right surface of filter box 1, it is the exhaust channel for purified airflow. The first filter screen 6 on the inner wall can perform final filtration on the airflow to be discharged, intercepting residual fine dust, ensuring that the discharged gas meets environmental protection requirements, and avoiding secondary pollution.
[0023] PLC electrical control box 4: Fixed on the front surface of filter box 1, it is the control core of the device. It is electrically connected to battery 5, motor 9, anode plate 12, etc. It can precisely control the start and stop of each component and the operating parameters to realize the automated coordinated operation of physical filtration, electrostatic adsorption and vibration cleaning.
[0024] Battery 5: Installed on the upper surface of filter box 1, it provides stable power support for electrical components such as PLC control box 4, motor 9, anode plate 12, and vibration motor 14, ensuring that the device can still work normally in the absence of external power supply or in the event of a sudden power outage, thereby improving the reliability of use.
[0025] First filter 6: Fixed to the inner wall of exhaust pipe 3, located at the end of airflow discharge, it is a fine filter component that can intercept fine pigment dust particles remaining after pretreatment, further purify the airflow, ensure the cleanliness of the finally discharged gas, and prevent dust leakage.
[0026] The second filter 7 is fixed on the inner wall of the air inlet duct 2 and is the first line of filtration for the airflow. It mainly intercepts larger particles of pigment dust in the dust-laden airflow, reduces the wear of large particles on subsequent components such as the anode plate 12 and the axial fan 10, and extends the service life of the equipment.
[0027] Dustproof housing 8: Fixed in the inner wall of filter box 1, it is specially designed to protect motor 9. It can prevent pigment dust from entering the motor 9, avoid dust adhesion that may cause motor 9 to malfunction, wear or short circuit, and ensure long-term stable operation of motor 9.
[0028] Motor 9: Fixed on the inner surface of the dustproof housing 8, the output shaft passes through the left surface of the dustproof housing 8 and is connected to the axial fan 10. It is the power source of the axial fan 10. The start, stop and speed are controlled by the PLC control box 4 to provide continuous power for the airflow and drive the dust-laden airflow to complete the filtration and adsorption process.
[0029] Axial fan 10: Fixed at the output end of motor 9, it rotates at high speed under the drive of motor 9, generating directional airflow suction and thrust, guiding the dust-laden airflow into the air inlet pipe 2, passing through each filter and adsorption component in sequence, and finally being discharged from the exhaust pipe 3. It is the core power component for airflow circulation.
[0030] Dust collection hopper 11: Fixed on the upper surface of the bottom plate of filter box 1, and installed corresponding to anode plate 12. It is specifically designed to collect pigment dust that falls off anode plate 12. Its hopper-shaped structure can guide the dust to gather and facilitate subsequent cleaning, avoiding dust accumulation at the bottom of filter box 1 and causing secondary dust.
[0031] Anode plate 12: Installed below the top plate of filter box 1 via sliding roller 15, and generated by electrical connection with PLC control box 4. When dust-laden airflow passes through, pigment dust particles are electrostatically adsorbed on the surface of the plate, realizing the separation of dust and airflow. It is the core electrostatic adsorption component.
[0032] Fixed frame 13: Fixed on the outer surface of anode plate 12, mainly serving the functions of fixing and conducting. On the one hand, it strengthens the structure of anode plate 12, and on the other hand, it provides a mounting carrier for vibration motor 14, so as to evenly transmit the vibration force generated by vibration motor 14 to anode plate 12 and ensure the dust removal effect.
[0033] Vibration motor 14: Fixed on the outer surface of the fixed frame 13, and controlled by the PLC control box 4 to start and stop. When working, it generates high-frequency vibration force, which is transmitted to the anode plate 12 through the fixed frame 13. This causes the pigment dust adsorbed on the surface of the anode plate 12 to fall off due to vibration and fall into the dust collection hopper 11 below, thus realizing the automatic dust removal of the anode plate 12.
[0034] Sliding roller 15: It is slidably sleeved in the inner wall of the top plate of the filter box 1, and the lower end is fixedly connected to the anode plate 12, providing a sliding installation support for the anode plate 12. It allows the anode plate 12 to vibrate up and down slightly under the action of the vibration motor 14, which not only ensures smooth vibration cleaning, but also limits the vibration range of the anode plate 12 and avoids collision with other components.
[0035] Spring 16: Both ends are fixed to the upper surface of the anode plate 12 and the lower surface of the top plate of the filter box 1, respectively. It is in a compressed state. On the one hand, it provides elastic support for the anode plate 12. On the other hand, after the vibration motor 14 stops working, it drives the anode plate 12 back to the initial position through elastic reset, while buffering vibration impact and protecting the structure of the device.
[0036] Working Principle: The PLC control box 4 starts the motor 9. Under the protection of the dustproof housing 8, the motor 9 drives the axial flow fan 10 to rotate at high speed, forming a directional negative pressure airflow field inside the filter box 1. The airflow containing pigment dust enters the device from the air inlet pipe 2 under the action of negative pressure suction. It first passes through the second filter screen 7 on the inner wall of the air inlet pipe 2. The second filter screen 7, as the first physical filtration barrier, can intercept large-diameter pigment dust particles in the airflow. This not only reduces the wear of large dust particles on the subsequent anode plate 12 and axial flow fan 10, but also reduces the load of subsequent electrostatic adsorption. The airflow that has passed through the initial filtration continues to flow into the electrostatic adsorption area inside the filter box 1 under the thrust of the axial flow fan 10. During this stage, the battery 5 provides stable power to the motor 9 and the PLC control box 4, while the dustproof housing 8 effectively prevents dust from entering the motor 9, ensuring the stable operation of the power system. When the airflow that has passed through the initial filtration flows through the anode plate 12 area... At this time, the PLC control box 4 has supplied power to the anode plate 12, forming a high-intensity electrostatic field on its surface. The pigment dust particles are in a charged state in the airflow. When the dust particles pass through the electrostatic field of the anode plate 12, they are adsorbed onto the surface of the anode plate 12 by the Coulomb force, achieving efficient separation of dust and airflow. As the adsorption process continues, the dust layer on the surface of the anode plate 12 gradually thickens, which will lead to a decrease in electrostatic adsorption efficiency. According to the preset program or dust concentration feedback, the PLC control box 4 starts the vibration motor 14. The vibration motor 14 is fixed on the fixing frame 13 on the outer surface of the anode plate 12. When working, it generates high-frequency vibration force, which is evenly transmitted to the entire anode plate 12 through the fixing frame 13. Under the action of vibration force, the anode plate 12 vibrates up and down slightly along the sliding roller 15. The pigment dust adsorbed on the surface loses its adhesion due to vibration and falls off the surface of the electrode plate, falling into the dust collection hopper 11 installed below corresponding to the anode plate 12.
