Description

Technical Field

[0001] The invention relates to the field of color-coated plate production equipment, and in particular to a dust removal device for producing raw materials of VOC environmentally friendly color-coated plates. Background Art

[0002] In the production process of VOC environmentally friendly color-coated sheets, the quality of raw materials plays a vital role in the quality of the final product. However, due to the diverse sources of raw materials, they are often mixed with various dust particles, which not only affect the purity of the raw materials, but also cause many problems in the subsequent processing process.

[0003] For example, during the coating process of color-coated boards, dust may be mixed into the coating material, destroying the uniformity and adhesion of the coating, and easily leading to uneven surface, uneven color, decreased corrosion resistance and other quality problems of the color-coated boards. In addition, the dust dispersed in the production workshop will pollute the working environment and ecological environment, and may cause respiratory diseases after being inhaled by workers, which will affect the workers' health. At the same time, when traditional dust removal equipment is used to process raw materials for color-coated boards, it may have problems such as low dust removal efficiency, poor treatment effect on dust of different particle sizes and properties, low degree of automation, and difficulty in integration with the entire color-coated board production line. It cannot meet the current high standards for raw material dust removal in the production process of VOC environmentally friendly color-coated boards.

[0004] Therefore, based on the above factors, the present invention is committed to developing an efficient, environmentally friendly, and automated raw material dust removal device, which is of great significance for improving the production quality of color-coated plates and promoting environmentally friendly production. Summary of the invention

[0005] The purpose of the present invention is to provide a dust removal device specifically for VOC environmentally friendly color-coated plate production raw materials. The device can efficiently remove dust from the raw materials, and through reasonable structural design and functional integration, realize automatic control and real-time monitoring, ensure the cleanliness of the raw materials, improve production efficiency, reduce environmental pollution, and thus ensure the high-quality production of color-coated plate products.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] Dust removal device frame structure: The core frame part of this device is a hollow cylindrical structure, which provides support and accommodation space for the entire dust removal device. This structure can not only protect the internal equipment components, but also guide the movement direction of dust and airflow, ensuring that the dust removal process is carried out in a relatively closed environment and preventing dust from spilling.

[0008] Exhaust cylinder structure 1 and exhaust cylinder structure 2: exhaust cylinder structure 1 and exhaust cylinder structure 2 are arranged side by side on the upper part of the dust removal device frame structure, and are interconnected with the inside of the dust removal device frame structure; both exhaust cylinder structures are connected to the exhaust fan through the fan connection part, and the cross-sectional radius gradually increases from top to bottom, forming a frustum-shaped structure. This structural design helps to expand the exhaust area and improve the exhaust efficiency, so that the dust-containing air can be more effectively sucked into the exhaust cylinder. When the exhaust fan is started, a negative pressure environment can be formed in the dust removal device frame structure, guiding the dust to gather towards the exhaust cylinder for subsequent treatment.

[0009] Dust collection pool: It is set at the bottom of the dust removal device frame structure, and its main function is to collect and process dust. The middle part is connected with drainage hole 1 and drainage hole 2. The cross-sectional radius of these two drainage holes gradually decreases from top to bottom, presenting an inverted frustum structure, which is convenient for the discharge of dust after precipitation. An electric water pump is connected to one side of the dust collection pool, and the water in the pool can be circulated or discharged as needed. A liquid level sensor is set in the dust collection pool to monitor the liquid level information in the pool and feed the information back to the central processor.

[0010] Raw material conveying device: It is movably arranged inside the frame structure of the dust removal device. It is a rectangular structure without a cover. The bottom and sides are both mesh hollow structures. The hollow aperture of the mesh hollow structure is between 1-5mm. This structure enables the dust to fall through the hollow part or be sucked away by the exhaust system during the conveying of the raw materials. Several groups of raw material conveying devices are provided according to actual use requirements, and hollow connecting pipe structures for connecting adjacent raw material conveying devices are provided on both sides of the bottom, so as to facilitate the combination and expansion of multiple groups of raw material conveying devices to meet the production needs of different scales. Several groups of roller structures are arranged under the raw material conveying device. The frame structure of the dust removal device can oscillate and slide above the roller structure by being pulled by the conveying motor, so that the raw material can generate a certain vibration during the conveying process, which is conducive to the separation and falling of dust.

[0011] Rotating rod: It is arranged on the inner side of the frame structure of the dust removal device, and its two ends are respectively connected to the inner walls on both sides of the frame structure of the dust removal device, and the roller structure is sleeved on the outer periphery of the rotating rod. At the same time, in order to ensure the stability and reliability of the connection between the roller structure and the rotating rod and prevent the loosening or damage of the components due to long-term operation, the two are connected by interference fit and circumferentially fixed by high-strength keys; at the connection between the roller structure and the rotating rod, apply an appropriate amount of high-performance grease to reduce friction loss and further improve the reliability and service life of the connection.

[0012] Central processor: STC89C52RC series chip is used as the core control unit of the whole device, which is electrically connected with the exhaust fan, water pump, transmission motor, video monitoring device and device control end respectively; the central processor accurately adjusts the wind speed of the exhaust fan, the speed of the transmission motor and the working state of the water pump according to the environmental parameters and equipment feedback signals such as the image information from the video monitoring device, the level sensor information of the dust-absorbing water, the wind speed sensor information of the exhaust fan, and the speed sensor information of the transmission motor, so as to ensure the efficient and stable operation of the dust removal device.

[0013] Preferably, the central processor controls the electric water pump to start the drainage operation according to the liquid level information in the dust collection pool when the liquid level reaches a preset high level, and controls the electric water pump to stop the drainage operation when the liquid level reaches a preset low level; according to the wind speed information of the exhaust fan, when the wind speed is lower or higher than a preset reasonable range, the power of the exhaust fan is adjusted to maintain it within an appropriate wind speed range; according to the speed information of the conveying motor, when the speed deviates from the preset normal speed range, the speed of the conveying motor is adjusted to ensure that the conveying speed of the raw materials meets the dust removal process requirements.

[0014] Video monitoring device: including high-definition cameras distributed on the inside and outside of the dust removal device frame structure, which are used to monitor the internal and external working conditions of the dust removal device in real time, such as the raw material transmission status, dust collection status, equipment operation status, etc., to facilitate operators to conduct remote observation and fault diagnosis.

[0015] Device control terminal: As a human-computer interaction interface, the operator can input operating instructions, view equipment status information, and adjust and set various parameters of the equipment through the control terminal, such as the wind speed of the exhaust fan, the speed of the transmission motor, the start and stop of the water pump, etc.

[0016] Wind speed sensor and rotation speed sensor: installed on the exhaust fan and transmission motor respectively, used to monitor the wind speed of the exhaust fan and the rotation speed of the transmission motor in real time, and feed back the monitoring data to the central processor.

[0017] In summary, due to the adoption of the above technical solution, the present invention has the following advantages compared with the prior art:

[0018] 1. Excellent dust removal effect. Through the combined effect of the special cone-shaped structure design of the exhaust tube structure, the mesh hollow structure of the raw material conveying device and the dust collection pool, the dust in the raw materials can be effectively removed to ensure the cleanliness of the raw materials entering the subsequent production process, significantly improve the product quality of the color-coated plate, and reduce product defects and quality problems caused by dust;

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The working principle of the dust removal device for producing raw materials of VOC environmentally friendly color-coated plates of the present invention is as follows:

[0031] When the work starts, the raw material is placed on the raw material conveying device 5, and the conveying motor drives the raw material conveying device 5 to oscillate and slide on the roller structure 10. The dust generated by the vibration during the conveying process of the raw material will fall through the mesh hollow structure. At the same time, the exhaust fan is started, and a negative pressure environment is formed in the dust removal device frame structure 1 through the exhaust cylinder structure 1 2 and the exhaust cylinder structure 2 4, and the dusty air above and around the raw material is sucked in. The inhaled dusty air will flow in the exhaust cylinder structure. Due to the cone-shaped design of the exhaust cylinder structure, the air flow speed changes, and the dust is driven by the air flow to gather at the bottom of the exhaust cylinder structure. A part of the heavier dust will fall directly into the dust collection pool 8 under the action of gravity, while the lighter dust will continue to move with the air flow.

[0032] The water in the dust collection pool 8 can capture and precipitate some dust, further purifying the air. The liquid level sensor in the dust collection pool 8 monitors the liquid level information in real time and feeds it back to the central processor. When the liquid level reaches the preset high level, the central processor controls the electric pump 12 to start the drainage operation to discharge the water containing dust; when the liquid level reaches the preset low level, the central processor controls the electric pump 12 to stop the drainage operation. At the same time, the video monitoring device monitors the working status of the equipment in real time and transmits the image information to the central processor, and the operator can view the information through the device control terminal.

[0033] The wind speed sensor on the exhaust fan feeds back the wind speed information to the central processor. When the wind speed is lower or higher than the preset reasonable range, the central processor adjusts the power of the exhaust fan to keep the wind speed within the appropriate range. The speed sensor on the conveying motor feeds back the speed information to the central processor. When the speed deviates from the preset normal speed range, the central processor adjusts the speed of the conveying motor to ensure that the conveying speed of the raw materials meets the dust removal process requirements.

[0034] During the entire process, the central processor precisely controls each component based on feedback from various sensors and preset programs to ensure the efficiency and stability of the dust removal process.

[0035] The specific embodiments are:

[0036] Embodiment 1:

[0037] First, the specific use process of the product of the present invention: according to the actual use requirements, multiple groups of raw material conveying devices 5 are assembled through the hollow connecting pipe structure 11 and placed inside the dust removal device frame structure 1. The roller structure 10 and the rotating rod 9 are connected by interference fit, and a suitable high-strength flat key is selected for circumferential fixation to ensure a firm connection, and high-performance grease is applied at the connection. Then the conveying motor is connected to the roller structure 10 to ensure that the raw material conveying device 5 can stably oscillate and slide on the roller structure 10.

[0038] The exhaust fan is adjusted to be tightly connected to the exhaust cylinder structure 1 2 and the exhaust cylinder structure 2 4 through the fan connection part 3, the electric water pump 12 is connected to the dust suction pool 8, and a proper amount of water is injected into the dust suction pool 8 so that the initial liquid level is about one-third of the height of the dust suction pool 8. At the same time, a liquid level sensor is installed in the dust suction pool 8, a wind speed sensor is installed on the exhaust fan, and a speed sensor is installed on the transmission motor.

[0039] The STC89C52RC series chip is used as the central processor, which is electrically connected to the exhaust fan, water pump, conveying motor, video monitoring device and device control end to complete the circuit wiring and system debugging; the initial wind speed of the exhaust fan X m / s and the initial speed of the conveying motor Y r / min are set by the central processor, and these two parameters can be adjusted within the range of ±30% through the device control end according to different raw material types and dust amounts.

[0040] Turn on the device and place the raw materials for color-coated plate production evenly on the raw material conveying device 5. The aperture of the mesh hollow structure of the raw material conveying device 5 is 0.5-0.8 times the particle size of the raw material to ensure effective separation of dust. Start the conveying motor and make the raw material conveying device 5 start to convey the raw materials at an appropriate speed and oscillation amplitude.

[0041] At the same time, start the exhaust fan and adjust it to the appropriate wind speed to form the negative pressure environment required for dust removal. Observe the image of the video monitoring device and fine-tune the equipment parameters through the device control terminal to ensure the smooth progress of the dust removal process.

[0042] After working for a period of time, according to the dust precipitation in the dust collection pool 8, the electric water pump 12 can be controlled by the device control end to discharge the dust-containing water from the drainage hole 1 6 or the drainage hole 2 7, and the dust can be centrally processed.

[0043] Embodiment 2:

[0044] When the production scale is large, according to actual needs, the number of groups of raw material conveying devices 5 is increased and used in combination, and they are connected in sequence through the hollow connecting pipe structure 11. At the same time, the dust removal device frame structure 1 is lengthened and reinforced accordingly to ensure the stability of the entire structure.

[0045] At the same time, the connection between the roller structure 10 and the rotating rod 9 is also fixed by interference fit and high-strength flat key, and a sufficient amount of high-performance grease is applied to the connection.

[0046] And for specific raw materials, according to the characteristic of small dust particle size, the aperture of the mesh hollow structure of the raw material conveying device 5 is reduced to 0.3-0.5 times of the raw material particle size to improve the separation effect of fine dust.

[0047] According to the actual use requirements and the use effect of the test, for upgrading the exhaust fan, a larger power exhaust fan can be selected, and it can be connected to the exhaust cylinder structure 1 2 and the exhaust cylinder structure 2 4. The initial wind speed of the exhaust fan set by the central processor can be increased to X1 m / s through the device control end, and the speed of the conveying motor can be increased to Y1 r / min to speed up the processing of raw materials.

[0048] A liquid level sensor can be added to the dust collection pool 8 to ensure the effectiveness of water level monitoring. The water level can be adjusted to about half the height of the dust collection pool 8, and an appropriate amount of flocculant can be added to enhance the dust sedimentation effect. At the same time, a wind speed sensor and a rotation speed sensor can be installed on the exhaust fan and the conveying motor respectively.

[0049] After starting the equipment, the production raw materials are continuously fed into the raw material conveying device 5. During operation, the dust removal effect and equipment status are observed through the video monitoring device. According to the feedback information from the video monitoring and the central processor, the wind speed of the exhaust fan, the speed of the conveying motor and the working status of the electric water pump 12 are adjusted in time to ensure the efficient operation of the dust removal device.

[0050] Embodiment 3:

[0051] When processing certain raw materials with sticky dust, the raw material conveying device 5 is specially processed by coating a layer of low friction coefficient coating on the surface of the mesh hollow structure to prevent the raw materials from adhering to the device due to sticky dust and affecting the dust removal effect.

[0052] The roller structure 10 and the rotating rod 9 adopt a slightly larger interference fit, and a wedge key is used for circumferential fixation. The self-locking property of the wedge key can further enhance the stability of the connection. Increase the frequency and amount of high-performance grease to prevent sticky dust from entering the connection and affecting the connection effect and equipment operation stability.

[0053] The oscillation amplitude of the conveying motor is reduced, and the exhaust power of the exhaust cylinder structure 1 2 and the exhaust cylinder structure 2 4 is increased, so as to improve the strength of the negative pressure environment and better absorb the sticky dust.

[0054] The water temperature in the dust collection pool 8 is adjusted to maintain it at a suitable specific temperature to change the physical properties of the water and improve the ability to capture sticky dust. At the same time, a suitable amount of surfactant can be added to the dust collection pool 8 as needed to reduce the surface tension of the water, so that the sticky dust is more easily captured by the water.

[0055] A liquid level sensor is installed in the dust collection pool 8, and a wind speed sensor and a rotation speed sensor are installed on the exhaust fan and the conveying motor respectively, so that the central processor can accurately control the operating status of the equipment.

[0056] The operating status of the equipment is closely monitored through the device control end. When it is found that the performance of the equipment has declined due to sticky dust, the wind speed of the exhaust fan, the speed of the transmission motor and the working parameters of the electric water pump 12 can be remotely adjusted through the control end to ensure that the dust removal process continues to proceed efficiently.

[0057] In the above three embodiments, through the coordinated work of various components, efficient dust removal treatment of VOC environmentally friendly color-coated plate production raw materials can be achieved, ensuring the cleanliness of raw materials for color-coated plate production and the environmental friendliness of the production process. In practical applications, the size of the device, the power of the exhaust fan, the speed of the transmission motor, the aperture of the hollow structure, the parameters of the dust collection pool, etc. can be appropriately adjusted according to different production scales, raw material characteristics and dust removal requirements to achieve the best dust removal effect and solve the dust removal problem.

[0058] The embodiments described above are only used to illustrate the technical ideas and features of the present invention, and their purpose is to enable technicians in this field to understand the contents of the present invention and implement them accordingly. The patent scope of the present invention cannot be limited only by this embodiment, that is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
