Description

Technical Field

[0001] This application relates to the field of refractory material production technology, and in particular to a dust removal device for mixing refractory materials. Background Technology

[0002] Materials whose physicochemical properties allow them to be used in high-temperature environments are called refractory materials. There are many ways to classify refractory materials, including classification by chemical properties, chemical mineral composition, production process, and material morphology. During the production of refractory materials, binders are generally added to the raw materials to increase their strength. A large amount of dust is often generated during the mixing process of refractory materials. To avoid the harm of dust to workers during the mixing process, dust collection devices are needed to absorb and purify the dust.

[0003] Existing dust removal devices for refractory material mixing mainly consist of a dust collection box, a dust extraction fan installed inside the dust collection box, a dust extraction pipe installed on the dust extraction fan, and a filter bag installed at the air outlet of the dust extraction fan. In use, this type of dust removal device works by inserting the dust extraction port of the dust extraction fan into the mixing device, and then drawing the dust-laden gas from the mixing device into the filter bag. This removes dust during the refractory material mixing process. For example, a refractory material mixing dust removal device disclosed in patent document CN202121235033.6 can use the above method to remove dust from the refractory material mixing device.

[0004] While existing dust removal devices can remove dust from refractory material mixing devices, the dust removal process is not continuous because the filter bags are full and it takes a long time to replace them. This reduces the efficiency of the dust removal device and makes it difficult to achieve efficient dust removal during the refractory material mixing process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a dust removal device for refractory mixing that combines layered filtration with automatic cleaning and discharge, and has high dust removal efficiency.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A dust collection device for mixing refractory materials includes a dust collection box. Three filter screens are installed inclinedly from top to bottom inside the dust collection box. A cleaning mechanism is installed at the top of each filter screen, comprising an electric actuator and a scraper. A discharge pipe is installed on the long side wall of the dust collection box, opposite the discharge end of the filter screen. A baffle mechanism is installed on the dust collection box between the discharge pipe and the filter screen, comprising a baffle plate, an electric telescopic rod, a support plate, and through holes. The filter screens are arranged inclined downwards from the side wall of the dust collection box away from the discharge pipe towards the discharge pipe. The telescopic part of the electric actuator is connected to the scraper. There are two through holes, the size of which matches the internal size of the discharge pipe.

[0008] Optionally, the telescopic part of the electric actuator passes through the side wall of the dust collector and slides with the dust collector, and the electric actuator is inclined upward along the slope of the dust filter plate.

[0009] Optionally, the dust filter screen is bolted to the dust collector box, and the bottom end of the scraper plate contacts the upper side of the dust filter screen.

[0010] Optionally, a sliding cavity is provided on the outside of the baffle plate in the dust collection box, and the baffle plate slides in conjunction with the sliding cavity.

[0011] Optionally, one end of the electric telescopic rod is connected to the baffle plate, and the other end of the electric telescopic rod is connected to the baffle plate.

[0012] Optionally, the area and shape of the via are matched with the area and shape of the feed port on the upper side of the discharge pipe.

[0013] Optionally, a dust collection mechanism is also installed on the top of the dust collection box, which includes a dust collection fan, a dust collection pipe, and a dust collection hood.

[0014] Optionally, the vacuum fan is installed at the top center of the dust collection box, and the vacuum pipe is installed between the vacuum hood and the vacuum fan.

[0015] Optionally, a support leg is welded to each of the four corners at the bottom of the dust collector, and an air outlet pipe is installed in the middle of the bottom of the dust collector.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This invention features three filter screens installed sequentially from top to bottom inside a dust collector. A cleaning mechanism consisting of a scraper and an electric push rod is installed at the top of each filter screen. Simultaneously, an inclined discharge pipe is installed at the discharge end of each filter screen, and a baffle mechanism consisting of a baffle plate, an electric telescopic rod, and a support plate is installed at the discharge end of the discharge pipe and the filter screen. This allows for the layered filtration of dust-laden gas drawn into the dust collector during the mixing of refractory materials, using the filter screens. The filtered dust particles... The particles are trapped on the dust filter screen, and as the electric actuator pushes the scraper plate to move, the dust particles on the filter screen are discharged to the discharge pipe. During discharge, the baffle plate in the baffle mechanism moves upward along the sliding cavity under the action of the electric telescopic rod to ensure that the through holes on the baffle plate are aligned with the corresponding discharge pipe ports. Because the filtered dust particles are cleaned by automatic scraping in this dust removal method, the tedious manual cleaning operation is eliminated, the downtime of the dust collection device is reduced, and the dust collection efficiency of the device in the refractory material mixing process is improved.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] To better understand the technical solutions shown in the embodiments of this application, the working principle of the existing dust removal device for mixing refractory materials will be introduced first.

[0025] The existing dust removal device for refractory material mixing mainly consists of a dust collection box, a dust extraction fan installed inside the dust collection box, a dust extraction pipe installed on the dust extraction fan, and a filter bag installed at the air outlet of the dust extraction fan. When using this type of dust collection device, the dust extraction port on the dust extraction fan is inserted into the mixing device, and then the dust-laden gas in the mixing device is drawn into the filter bag by the dust extraction fan, thereby removing dust from the refractory material mixing device during the mixing process.

[0026] Please see Figures 1-4 This application discloses a dust removal device for mixing refractory materials, comprising a dust collection box 4. Three dust filter plates 6 are installed in an inclined manner from top to bottom inside the dust collection box 4. A cleaning mechanism 5 is installed at the top of each dust filter plate 6 inside the dust collection box 4. The cleaning mechanism 5 includes an electric push rod 51 and a scraper 52. A discharge pipe 3 is installed on the long side wall of the dust collection box 4, opposite the discharge end of the dust filter plate 6. A baffle mechanism 2 is installed on the dust collection box 4 between the discharge pipe 3 and the dust filter plate 6. The baffle mechanism 2 includes a baffle plate 21, an electric telescopic rod 22, a support plate 23, and a through hole 24. The dust filter plates 6 are arranged in a downward inclined manner from the side wall of the dust collection box 4 facing away from the discharge pipe 3 towards the discharge pipe 3. The telescopic part of the electric push rod 51 is connected to the scraper 52. There are two through holes 24, the size of which matches the internal size of the discharge pipe 3.

[0027] Specifically, when the dust-laden gas during the refractory material mixing process is drawn into the dust collector 4, the dust particles in the gas are filtered by the dust filter plate 6. When the dust filter plate 6 is full of dust particles, the baffle plate 21 is opened by the electric telescopic rod 22 to ensure that the upper end of the discharge pipe 3 is connected to the discharge end of the corresponding dust filter plate 6. Then, the scraper plate 52 is moved down along the dust filter plate 6 by the electric push rod 51 to scrape the filtered dust particles on the dust filter plate 6 into the discharge pipe 3. The filtered dust particles can then be discharged by the discharge pipe 3 for subsequent reuse.

[0028] Please see Figure 1 and Figure 2 The telescopic part of the electric actuator 51 penetrates the side wall of the dust collector 4 and slides with the dust collector 4. The electric actuator 51 is distributed in an inclined manner along the inclined surface of the dust filter plate 6.

[0029] As one implementation method, the electric telescopic part is slidably engaged with the dust collection box 4, which ensures that the telescopic part of the electric push rod 51 can slide conveniently relative to the side wall of the dust collection box 4. At the same time, the electric push rod 51 is installed in an inclined manner, which ensures that the electric push rod 51 can be extended and adjusted along the surface of the dust filter plate 6.

[0030] Please see Figure 2The dust filter screen 6 is bolted to the dust collector box 4, and the bottom end of the scraper plate 52 contacts the upper side of the dust filter screen 6.

[0031] As one implementation method, the bolted connection makes the dust filter plate 6 more securely fixed in the dust collection box 4, while the scraper plate 52 can conveniently discharge the filtered dust particles from the dust filter plate 6.

[0032] Please see Figure 2 and Figure 3 The dust collector 4 is also provided with a sliding cavity 9 on the outside of the baffle plate 21, and the baffle plate 21 and the sliding cavity 9 are slidably engaged.

[0033] As one implementation, the sliding cavity 9 can ensure convenient up-and-down sliding adjustment of the baffle plate 21 relative to the side wall of the dust collection box 4.

[0034] Please see Figure 1 , Figure 3 and Figure 4 One end of the electric telescopic rod 22 is connected to the baffle plate 21, and the other end of the electric telescopic rod 22 is connected to the baffle plate 21.

[0035] As one implementation method, the baffle plate 21 is connected to the electric telescopic rod 22, which allows the baffle plate 21 to be conveniently raised and lowered under the action of the electric telescopic rod 22.

[0036] Please see Figure 1 The area and shape of the through hole 24 match the area and shape of the feed port on the upper side of the discharge pipe 3.

[0037] In one implementation, the area of ​​the through hole 24 corresponds to the area of ​​the inlet at the top of the discharge pipe 3. When the through hole 24 is directly opposite the inlet of the discharge pipe 3, the discharge end of the dust filter plate 6 is connected to the discharge pipe 3. At this time, the bottom of the through hole 24 just blocks the hollow structure on the side wall of the dust collector 4 where the baffle plate 21 slides, ensuring that the cleaned dust particles on the dust filter plate 6 can smoothly enter the discharge pipe 3.

[0038] Please see Figure 1 The dust collection box 4 is also equipped with a dust collection mechanism 1 at the top. The dust collection mechanism 1 includes a dust collection fan 13, a dust collection pipe 12, and a dust collection hood 11.

[0039] In one implementation, after the dust extraction fan 13 is started, it will absorb the dust on the refractory material mixing device under the action of the dust extraction pipe 12 and the dust extraction hood 11.

[0040] Please see Figure 1 The vacuum cleaner fan 13 is installed at the top center of the dust collection box 4, and the vacuum pipe 12 is installed between the vacuum hood 11 and the vacuum cleaner fan 13.

[0041] In one implementation, the suction pipe 12 can facilitate the transport of dust-laden gas sucked up by the suction hood 11 to the suction fan 13, so that the dust-laden gas can be drawn into the dust collection box 4 under the action of the suction fan 13.

[0042] Please see Figure 1 and Figure 2 At the bottom of the dust collector 4, a support leg 8 is welded at each of the four corners, and an air outlet duct 7 is installed in the middle of the bottom of the dust collector 4.

[0043] As one implementation method, the support leg 8 can ensure the stable placement of the dust collection box 4, and the air outlet pipe 7 is mainly used to ensure the convenient discharge of filtered gas inside the dust collection box 4.

[0044] The specific working principle is as follows: First, the dust suction hood 11 is inserted into the refractory material mixing device. Then, under the action of the dust suction fan 13, the dust-laden gas inside the refractory material mixing device is drawn through the dust suction pipe 12 to the dust collection box 4. After entering the dust collection box 4, the dust-laden gas is filtered and removed by the dust filter plate 6. The filtered gas is discharged through the discharge pipe 3. When a large amount of particles accumulates on the dust filter plate 6 and needs to be cleaned, the baffle plate 21 is first moved upward along the sliding cavity 9 under the action of the electric telescopic rod 22 to ensure... The through hole 24 on the baffle plate 21 can be aligned with the corresponding discharge pipe 3 port. Then, the electric push rod 51 drives the scraper plate 52 to move, so that the dust particles trapped on the surface of the dust filter plate 6 can be pushed to the discharge pipe 3 under the action of the scraper plate 52, thereby realizing the automatic cleaning of the dust filter plate 6. Since the filtered dust particles are cleaned by automatic scraping in this dust removal method, the tedious operation of manual cleaning is eliminated, the downtime of the dust collection device is reduced, and the dust collection efficiency of the device in the refractory material mixing process is improved.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
