Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dust collector cleaning equipment, specifically to an energy-saving dust collector cleaning device for VIGA dust collectors based on pressure difference and temperature dual control. Background Technology
[0002] The VIGA dust collector is a high-efficiency dust removal device, belonging to the category of pulse jet dust collectors. The VIGA dust collector utilizes advanced pulse jet technology, offering advantages such as high dust removal efficiency, large gas handling capacity, stable and reliable operation, and convenient maintenance.
[0003] VIGA dust collectors mostly use bag filters. Traditional bag filters, when their dust removal capacity decreases, usually require the cleaning components to be activated to blow off the dust adsorbed on the filter bags. In this process, the dust in the collection hopper at the bottom of the dust collector will inevitably be blown away and re-raised. When the blowing operation stops, the dust will re-adhere to the filter bags, which to some extent reduces the dust removal efficiency of the bag filter, increases the cleaning frequency of the bag filter, increases unnecessary energy consumption, and reduces the service life of the bag filter. Utility Model Content
[0004] In view of this, the present invention provides an energy-saving dust removal device for VIGA dust collectors based on pressure difference and temperature dual control. It can guide and block the dust isolated by the filter bags of the bag dust collector by setting the guide component at the bottom of the dust collector, so as to prevent it from being raised and adhering to the outside of the filter bags, reducing the dust removal efficiency and cleaning frequency of the bag dust collector, and increasing the service life of the bag dust collector.
[0005] To address the aforementioned technical problems, this utility model provides an energy-saving dust removal device for a VIGA dust collector based on differential pressure and temperature dual control. The dust removal device is installed inside the bag filter, with the inlet of the bag filter connected to the VIGA's discharge port. A collection mechanism for collecting filtered dust is located at the lower end of the bag filter. This collection mechanism includes a guide assembly at the lower end of the bag filter, with a collection box located below the guide assembly. The guide assembly guides the dust from the lower end of the bag filter into the collection box. A control assembly is also installed on the bag filter, electrically connected to the bag filter's electrical control unit. This utility model uses the guide assembly to guide the dust isolated inside the bag filter, ensuring it smoothly enters the collection box and preventing it from remaining at the lower part of the bag filter. This dust is not allowed to remain and be stirred up during the dust removal process, re-adhere to the outside of the filter bags after cleaning, affecting the subsequent cleaning efficiency of the bag filter, increasing cleaning frequency, increasing energy consumption, and reducing the service life of the bag filter.
[0006] The guiding assembly includes a guide cylinder disposed between the lower part of the bag filter and the collection box. The guide cylinder is connected to both the bag filter and the collection box. A guide roller is rotatably mounted inside the guide cylinder. Multiple guide scrapers that abut against the side wall of the guide cylinder are mounted on the outer side wall of the guide roller. A drive unit is mounted on the outer side of the guide roller to drive its rotation. This invention can use the drive unit to rotate the guide roller and the guide scrapers on the outer side of the guide roller together, thereby continuously and smoothly guiding the dust at the bottom of the bag filter to the collection box. This greatly improves the dust removal efficiency at the bottom of the dust collector, allowing the dust to enter the collection box smoothly and be collected, significantly reducing the dust remaining at the bottom of the dust collector.
[0007] The driving component includes a servo motor mounted on the outer wall of the guide cylinder. A reducer is mounted on the output shaft end of the servo motor. The output end of the reducer is mounted together with the end of the guide roller. This invention can rotate the guide roller by rotating the output shaft of the servo motor and reducing the speed of the reducer. This will cause the guide scraper on the outer side of the guide roller to rotate together, thereby smoothly guiding the ash hopper falling from the collection hopper into the collection box.
[0008] The control components include pressure and temperature sensors installed inside the bag filter. A controller, a PLC controller, is also installed on the bag filter and electrically connected to the pressure and temperature sensors. This invention enables real-time dual monitoring of the bag filter's dust removal efficiency through the dual monitoring functions of the pressure and temperature sensors. This facilitates the controller in activating the cleaning device and drive components at appropriate times, ensuring that dust passing through the lower part of the bag filter falls smoothly into the collection box, making operation more convenient, efficient, and intelligent.
[0009] The baghouse dust collector includes a dust collection box, inside which are dust collection filter bags. Inside the dust collection box and above the dust collection filter bags, there are electromagnetic pulse valves, an air manifold, and a jet cleaning pipeline. The jet cleaning pipeline is located directly above the dust collection filter bags. A dust hopper is located at the bottom of the dust collection box and is connected to the upper part of a guide cylinder. This invention allows high-pressure gas to be blown directly into the dust collection filter bags through the air manifold and jet cleaning pipeline by activating the electromagnetic pulse valve, achieving efficient removal of dust adhering to the outside of the filter bags, greatly improving its subsequent filtration capacity and making operation more convenient.
[0010] The collection box has a drawer that slides inside. This utility model allows the operator to pull out the drawer to remove impurities from the ash hopper and perform centralized cleaning, making the operation more convenient and labor-saving.
[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0012] 1. Preventing secondary dust from re-adhering to the filter bag: This invention can efficiently and smoothly remove dust from the bottom of the bag filter by simultaneously activating the output shaft of the drive unit during the dust removal process, which drives the guide roller and guide scraper. This greatly reduces secondary dust generation after dust removal and thus prevents secondary dust adhesion to the outside of the filter bag.
[0013] 2. Dynamic dust removal control: Through the electrical connection between the controller in the control component and the dust removal device, as well as the pressure sensor and temperature sensor, the dust removal frequency and intensity can be dynamically adjusted, significantly improving the dust removal effect.
[0014] 3. Enhanced safety: Through the electrical connection between the control components and the electrical control unit in the bag filter, the various actuators of the bag filter can be started and stopped quickly and conveniently. It supports integration with the automated control system, realizes remote monitoring and dynamic adjustment, and improves the intelligence level of the equipment.
[0015] 4. Easy to collect dust: The dust hopper, which slides inside, allows for easy, convenient, and efficient removal of the collected dust, making operation more convenient. Attached Figure Description

Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0023] like Figure 1-5 As shown: This embodiment provides an energy-saving dust removal device for a VIGA dust collector based on differential pressure and temperature dual control. The dust removal device is installed inside a bag filter 100. The inlet of the bag filter 100 is connected to the discharge port of the VIGA. A collection mechanism 200 for collecting filtered dust is provided at the lower end of the bag filter 100. The collection mechanism 200 includes a guide assembly 210 located at the lower end of the bag filter 100. A collection box 220 is located below the guide assembly 210. The guide assembly 210 is used to guide the dust at the lower end of the bag filter 100 into the collection box 220. The bag filter 100 is also equipped with a control component 230, which is electrically connected to the electrical control unit of the bag filter 100. This utility model can guide the dust isolated inside the bag filter 100 through the guide component 210, so that it can smoothly enter the collection box 220, and avoid it remaining at the bottom of the bag filter 100. During the dust removal operation of the dust removal mechanism, it will be stirred up and re-adhere to the outside of the filter bag after the dust removal is completed, which will affect the subsequent cleaning efficiency of the bag filter 100, increase the cleaning frequency, increase energy consumption, and reduce the service life of the bag filter 100.
[0024] According to one embodiment of the present invention, such as Figure 1-2 As shown, the guiding assembly 210 includes a guiding cylinder 211 disposed between the lower part of the bag filter 100 and the collection box 220. The guiding cylinder 211 is in communication with the bag filter 100 and the collection box 220. A guide roller 212 is rotatably disposed inside the guiding cylinder 211. Multiple guide scrapers 213 that abut against the side wall of the guiding cylinder 211 are disposed on the outer side of the guide roller 212. A driving member 214 is disposed on the outer side of the guide roller 212 to drive its rotation. This utility model can use the driving member 214 to make the guide roller 212 and the guide scrapers 213 on the outer side of the guide roller 212 rotate together, so as to continuously guide the dust at the bottom of the bag filter 100 smoothly into the collection box 220, which greatly improves the dust removal efficiency at the bottom of the dust collector, so that it can smoothly enter the collection box 220 for centralized collection, and greatly reduce the dust remaining at the bottom of the dust collector.
[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the driving component 214 includes a servo motor mounted on the outer wall of the guide cylinder. A reducer 215 is mounted on the output shaft end of the servo motor. The output end of the reducer 215 is mounted together with the end of the guide roller 212. This invention can rotate the guide roller 212 by rotating the output shaft of the servo motor and reducing the speed by the reducer 215. This will cause the guide scraper 213 on the outer side of the guide roller 212 to rotate together, thereby smoothly guiding the ash hopper 103 falling from the collection hopper into the collection box 220.
[0026] According to another embodiment of the present invention, such as Figure 1 and Figure 5 As shown, the control component 230 includes a pressure sensor 231 and a temperature sensor 232 installed inside the bag filter 100. The pressure sensor 231 is a Miko brand model MIK-P300, and the temperature sensor 232 is a Microprobe model AT-WX-2000. The bag filter 100 is also equipped with a controller 233, which is a PLC controller model Siemens S7-300. The controller 233 is electrically connected to the pressure sensor 231 and the temperature sensor 232. This invention can achieve real-time dual monitoring of the dust removal efficiency of the bag filter 100 through the dual monitoring function of the pressure sensor 231 and the temperature sensor 232. This facilitates the controller 233 to start the dust removal device and the drive component 214 at the appropriate time, thereby enabling the dust passing through the lower part of the bag filter 100 to fall smoothly into the collection box 220, making the operation more convenient, efficient and intelligent.
[0027] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the bag filter 100 includes a dust collection box 101, inside which a dust collection filter bag 102 is installed. The dust collection filter bag 102 is a PPS filter bag. Inside the dust collection box 101 and above the dust collection filter bag 102, there is an electromagnetic pulse valve, an air tank, and a jetting pipe. The jetting pipe is located directly above the dust collection filter bag 102. A dust hopper 103 is installed at the bottom of the dust collection box 101. The dust hopper 103 is connected to the upper part of the guide cylinder 211. This invention can blow high-pressure gas through the air tank and jetting pipe into the dust collection filter bag 102 by activating the electromagnetic pulse valve, thereby achieving efficient blowing off of dust adhering to the outside of the dust collection filter bag 102, greatly improving its subsequent filtration capacity and making operation more convenient.
[0028] The collection box 220 has a drawer 300 that slides inside. The drawer 300 has a handle on the outside. The handle makes it easy for the operator to grab and pull the drawer 300 out of the collection box 220 and insert it into the collection box 220, making the operation more convenient. This utility model allows the operator to pull out the drawer 300 to remove and clean the impurities in the ash hopper 103, making the operation more convenient and labor-saving.
[0029] How to use this utility model:
[0030] First, it needs to be clarified that the dust removal device involved in this utility model is mainly used for filtering particles and dust in the exhaust gas generated by the VIGA equipment. The dust collector is the existing bag filter 100. This utility model will describe its usage in detail using the working principle of the dust removal device as an example. When it is necessary to clean the dust in the exhaust gas generated by the VIGA equipment, the controller 233 controls the induced draft fan to guide the exhaust gas generated by the VIGA equipment into the inlet of the bag filter 100. At this time, the outer side of the dust collection filter bag 102 of the bag filter 100 can be... To block dust, the blocked dust will concentrate at the bottom of the bag filter 100, and some will adhere to the outside of the dust filter bag 102. As the dust removal operation continues, the amount of dust adhering to the outside of the dust filter bag 102 will increase, and the filtration efficiency of the dust collector will decrease. At this time, the pressure detected by the pressure sensor 231 will decrease, and the temperature of the temperature sensor 232 will increase. At this time, the controller 233 can start the dust removal device and the drive unit 214 to work. At this time, the electromagnetic pulse valve can pressurize the gas in the booster pump and then... High-pressure gas is blown directly into the dust collector filter bag 102 through the air tank and the blowing pipe, achieving efficient removal of dust adhering to the outside of the filter bag 102. Simultaneously, the drive component 214 rotates the guide roller 212 and the guide scraper 213 on its outer side, continuously guiding the dust from the bottom of the baghouse dust collector 100 smoothly into the collection box 220. This significantly improves the dust removal efficiency from the bottom of the dust collector, ensuring it enters the collection box 220 for centralized collection and greatly reducing residual dust at the bottom of the dust collector. When the pressure sensor... After the temperature of the device 231 and the temperature sensor 232 returns to normal, the output shaft of the drive component 214 is turned off. At this time, the induced draft fan can be started again to continue the filtration of the exhaust gas generated by the VIGA equipment into the filter. This utility model can guide and block the dust isolated by the filter bags of the bag dust collector 100 through the guide component 210 set at the bottom of the dust collector, so as to avoid the dust being raised and adhered to the outside of the filter bags, reducing the dust removal efficiency and cleaning frequency of the bag dust collector 100, and increasing the service life of the bag dust collector 100.
[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
