Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a micro-powered dust removal device. Background Technology

[0002] The production processes in industries such as machinery manufacturing, building materials, cement, and coal generate a significant amount of dust. This is especially true in the coal transportation industry, where dust is produced during the conveyor belt transport of coal. If this dust is allowed to spill out, workers will inhale it during inspections, seriously endangering their health. If this dust is directly released into the atmosphere, it will also cause air pollution, severely damaging the living environment of people in the surrounding area. Therefore, it is necessary to filter and purify the dust generated during the production process.

[0003] The commonly used dust filtration and purification equipment in existing technology is the bag filter. It collects the surrounding dust into the dust collector through a fan. Once the dust exceeds the limit, the filter bags must be cleaned. This requires manual collection and disposal of the bags after dust collection. Since the collected dust is coal ash, discarding it would waste resources. Workers pour the coal ash from inside the bags onto a conveyor belt. Because the coal ash is concentrated, it does not cause large-scale overflow. However, this method often requires frequent cleaning of the bags, which is inconvenient as it requires stopping the dust collector during cleaning. Therefore, this technical solution is proposed to improve the process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in which dust generated during coal conveying on conveyor belts affects workers' health, and to provide a micro-powered dust removal device.

[0005] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a micro-powered dust removal device, including a support frame disposed above a conveyor belt, a collection chamber disposed at the lower part of the support frame, a filter device disposed inside the collection chamber, the filter device being connected to a dust removal device, an mounting plate disposed at the upper part of the filter device, a control chamber disposed above the mounting plate, a valve disposed inside the control chamber for controlling the opening and closing of the regulating chamber and the collection chamber, and a negative pressure fan disposed at the upper part of the control chamber.

[0006] Furthermore, the filtration device is a filter element, and the dust removal device is a dust removal pipe installed inside the filter element, and the dust removal pipe is connected to a pneumatic pulse valve.

[0007] Furthermore, the top of the filter element is a tripod, the dust removal pipe is vertically set in the middle of the tripod, the lower part of the dust removal pipe is connected to the filter element, the tripod is set inside the control chamber, the lower part of the filter element is set inside the collection chamber, the bottom of the control chamber is provided with a mounting hole, and the valve is set on the upper part of the dust removal pipe.

[0008] Furthermore, the valve is a pneumatic plate installed on the upper part of the dust removal pipe. The diameter of the pneumatic plate is larger than the diameter of the mounting hole, and a return spring is installed below the pneumatic plate.

[0009] Furthermore, the filter element is a filter cylinder, and multiple filter elements are provided. The interior of the dust removal pipe is hollow and connected to a pneumatic pulse valve.

[0010] The beneficial effects of this utility model embodiment are as follows: A tripod is set at the top of the filter element, and a dust collection pipe is set in the middle of the tripod. The dust collection pipe is hollow inside. The tripod is installed inside the control chamber, and the lower part of the filter element is set inside the collection chamber. A pneumatic plate is set inside the control chamber to control the opening and closing of the regulating chamber and the collection chamber. When the pneumatic pulse valve is working, the pneumatic plate moves downward to close the mounting hole, so that the filter element below does not have airflow entering temporarily, but the other filter elements work normally and do not affect the effect of the negative pressure fan. The filter element without airflow can quickly shake off a large amount of adsorbed dust when the airflow is sprayed out of the dust collection pipe. The dust falling onto the conveyor belt will not cause dust overflow. The fallen dust is recycled by the conveyor belt, reducing resource waste. The filter elements alternately remove dust to ensure the dust removal effect. After the dust removal is completed, the pneumatic pulse valve closes, and the pneumatic plate moves up under the action of the return spring to continue the filtration work, realizing the automatic dust removal function. There is no need for frequent manual cleaning of the filter elements, which greatly reduces the operation frequency. During the dust removal process, the device does not need to be stopped and can continuously carry out dust filtration, improving production efficiency. The collected dust can be directly recycled, avoiding resource waste and reducing the pollution of the environment caused by dust emissions. Attached Figure Description

[0015] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] See Figures 1 to 3 This utility model discloses a micro-powered dust removal device, including a support frame 2 installed above a coal conveying device. The device mainly comprises the support frame 2, a collection bin 3, a filter device, a dust removal device, a mounting plate, a control bin 6, valves, and a negative pressure fan 4. The support frame 2 serves as the supporting structure for the entire device, securely installed above the conveyor belt 1 at a suitable position, providing a mounting base for other components. The collection bin 3 is located at the lower part of the support frame 2, used to collect dust raised from the conveyor belt 1. The bottom of the collection bin 3 covers the top of the conveyor belt 1. When the negative pressure fan is operating, the collection bin 3 can increase the collection range above the conveyor belt 1, improving the efficiency. A filter device is installed inside the collection bin 3, using a filter element 5, specifically a filter cylinder. Multiple filters can be installed according to actual needs to enhance the filtration effect. A tripod 503 is installed on the top of the filter element 5, and a dust collection pipe 501 is installed in the middle of the tripod 503. The dust collection pipe 501 is hollow inside. The tripod 503 is installed inside the control chamber 6. The lower part of the filter element 5 is installed inside the collection chamber 3. An installation plate is installed on the upper part of the filter device. The installation plate serves to connect and support the control chamber 6. An installation hole 602 is provided at the bottom of the control chamber 6. During installation, the installation hole 602 is fitted with the inner hole of the filter element 5. During use, the airflow at the bottom is filtered by the filter element 5 and flows upward from the inside of the filter element 5, leaving the dust on the outside of the filter element 5. The filtered air enters the control chamber 6 through the installation hole 602 and is discharged by the negative pressure fan 4 installed at the top, thereby completing the filtration and adsorption of the surrounding air, reducing the dust content in the environment, preventing excessive adsorption by workers during inspection, and improving the use effect.

[0017] The filtration device is connected to a dust removal device, which is a dust removal pipe 501 installed inside the filter element 5. The dust removal pipe 501 is hollow inside, and a branch pipe is provided on the side of the dust removal pipe 501. Multiple air holes are provided on the side of the dust removal pipe 501 and the branch pipe. The top of the dust removal pipe 501 is connected to a pneumatic pulse valve 601, which is connected to the air tank of the air compressor. After a period of use, the pneumatic pulse valve 601 controls the dust removal pipe 501 and the branch pipe to spray high-pressure gas, which can realize the pulse dust removal operation of the filter element 5, extend the service life of the filter element 5, and improve the performance.

[0018] If the negative pressure fan 4 is constantly drawing air, the dust removal effect is limited. Therefore, a valve is installed inside the control chamber 6 to control the opening and closing of the regulating chamber and the collection chamber 3. The negative pressure fan 4, located at the top of the control chamber 6, provides negative pressure to the entire device, causing dust to enter the collection chamber 3. The valve is located at the top of the dust removal pipe 501, specifically as a pneumatic plate 502 located at the top of the dust removal pipe 501. The diameter of the pneumatic plate 502 is larger than the diameter of the mounting hole 602 at the bottom of the control chamber 6. A return spring 504 is installed below the pneumatic plate 502 and is controlled by the air source inside the dust removal pipe 501. During use, when dust removal is required for a single filter element 5, the pneumatic pulse valve... When 601 is working, the pneumatic plate 502 moves downward to close the mounting hole 602, causing the filter element 5 below to temporarily not have airflow entering. However, the other filter elements 5 work normally and do not affect the effect of the negative pressure fan 4. The filter element 5 without airflow can quickly shake off a large amount of adsorbed dust when the airflow is sprayed out of the dust removal pipe 501. The dust falls directly onto the conveyor belt 1 without causing dust overflow. The fallen dust is recycled through the conveyor belt 1, reducing resource waste. The filter elements 5 are used for dust removal in turn to ensure the dust removal effect. After the dust removal is completed, the pneumatic pulse valve 601 closes, and the pneumatic plate 502 moves upward under the action of the return spring 504 to continue the filtration work.

[0019] Working Principle: Under normal operating conditions, the negative pressure fan 4 starts. Under negative pressure, dust generated on the conveyor belt 1 is sucked into the collection chamber 3. At this time, the pneumatic plate 502 is in a specific position under the action of negative pressure and the return spring 504, maintaining communication between the regulating chamber and the collection chamber 3. Dust smoothly enters the collection chamber 3 and is filtered by the filter element 5. When it is necessary to clean the filter element 5, the pneumatic pulse valve 601 opens, and compressed air enters the interior of the filter element 5 through the dust removal pipe 501, generating a pulse airflow. Simultaneously, under the action of the pulse airflow, the pneumatic plate 502 overcomes the elasticity of the return spring 504 and moves downward, blocking the communication between the regulating chamber and the collection chamber 3, preventing dust from re-entering the regulating chamber during the cleaning process. The pulse airflow shakes off the dust adhering to the surface of the filter element 5, causing it to fall to the bottom of the collection chamber 3. After cleaning, the pneumatic pulse valve 601 closes, the pneumatic plate 502 resets under the action of the return spring 504, the regulating chamber and the collection chamber 3 are reconnected, and the device returns to normal filtration operation. The collected coal ash falls onto conveyor belt 1 for recycling, avoiding resource waste. Compared with existing baghouse dust collectors, the automatic dust removal function is achieved through the cooperation of pneumatic pulse valve 601 and other valves, eliminating the need for frequent manual cleaning of filter element 5, greatly reducing the operation frequency. During the dust removal process, the device does not need to be stopped and can continuously perform dust filtration, improving production efficiency. The collected dust can be directly recycled, avoiding resource waste and reducing dust emissions from polluting the environment.
