DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an amorphous refractory material conveying and dust-removing device includes a dust-proof component 1 composed of a material receiving hopper 101, a spherical cover 102, and a concave cover 103. The spherical cover 102 and the concave cover 103 are respectively fixed to the outer sides of the top and bottom of the material receiving hopper 101. The opening of the material receiving hopper 101 is located at the bottom of the upper conveyor belt, and the bottom of the material receiving hopper 101 is located at the upper end of the lower conveyor belt. The spherical cover 102 forms a dust-proof shield for the discharging end of the upper conveyor belt, and the concave cover 103 is used to form a dust-proof shield for the upper end of the lower conveyor belt. A dust-removing component 2 is arranged on one side of the dust-proof component 1, and the dust-removing component 2 is used to collect the dust inside the spherical cover 102 and the concave cover 103.

[0030] The dust - falling component 2 includes a dust - suction unit and an anti - blockage unit. The dust - suction unit is used for sucking and collecting dust, and the anti - blockage unit is used for cleaning the filtering parts in the dust - suction unit.

[0031] The dust - suction unit includes a dust - suction barrel 201, a first dust - suction pipe 204, a second dust - suction pipe 205, a filter cylinder 206, and a suction fan 209. A transmission chamber 202 and a collection chamber 203 are formed inside the dust - suction barrel 201. The collection chamber 203 is located below the transmission chamber 202. The first dust - suction pipe 204 and the second dust - suction pipe 205 are fixed on one side of the outer wall of the dust - suction barrel 201 and respectively penetrate to the inside of the spherical cover 102 and the concave cover 103. The first dust - suction pipe 204 and the second dust - suction pipe 205 are communicated with the inner cavity of the collection chamber 203.

[0032] The filter cylinder 206 is distributed inside the collection chamber 203 and penetrates to the inside of the transmission chamber 202. The suction fan 209 is fixed at the center of the top of the dust - suction barrel 201, and the suction port of the suction fan 209 is communicated with the inner cavity of the transmission chamber 202.

[0033] By the operation of the suction fan 209 to generate suction, the dust inside the spherical cover 102 and the concave cover 103 is sucked. The filter cylinder 206 is used for filtering dust, and the collection chamber 203 is used for collecting the filtered dust.

[0034] The anti - blockage unit includes a transmission gear 207, a drive motor 210, a driving gear 211, and a scraper 214. The transmission gears 207 are distributed inside the transmission chamber 202 and fixed on the outer side of the top of the filter cylinder 206. The drive motor 210 is fixed on one side of the top of the dust - suction barrel 201. The output end of the drive motor 210 penetrates to the inside of the transmission chamber 202 and is fixedly connected with the driving gear 211. The driving gear 211 meshes with the transmission gear 207.

[0035] The scraper 214 is fixed on one side of the inner wall of the collection chamber 203 and fits with the outer wall of the filter cylinder 206.

[0036] The drive motor 210 runs to drive the filter cylinder 206 to rotate, and the scraper 214 scrapes the wall of the rotating filter cylinder 206.

[0037] The anti - blockage unit further includes a partition plate 208, a fixing rod 212, and a sector baffle 213. There are multiple partition plates 208. The multiple partition plates 208 are evenly distributed in a ring and fixed inside the filter cylinder 206. The inner part of the filter cylinder 206 is divided into several ventilation cavities by the partition plates 208.

[0038] The fixed rod 212 is fixed to the top of the inner wall of the transmission bin 202. The sector baffle 213 is fixed to the bottom of the fixed rod 212 and fits against the top of the dust suction bucket 201. The ventilation cavity rotated to below the sector baffle 213 loses suction, facilitating the dust scraping operation on the outer wall of the dust suction bucket 201.

[0039] In this embodiment: It should be noted that when this device is in use, the feeding head 101 and the dust suction bucket 201 are fixed through an external support, and the dust-proof component 1 is located in the middle of the docking position of the two conveyor belts. The spherical cover 102 forms an obstruction to the end of the upper conveyor belt, and the concave cover 103 forms an obstruction to the shape above the lower conveyor belt.

[0040] During the process of the conveyor belt running to convey the raw materials of the unshaped refractory material, the upper conveyor belt conveys and drops the raw materials into the inside of the feeding head 101, and then drops them onto the lower conveyor belt through the internal channel of the feeding head 101, thus realizing the continuous conveyance of the raw materials. During this process, the dropping of the raw materials will cause the raw material dust of fine particles to disperse into the air. The spherical cover 102 and the concave cover 103 can block these raw material dusts and prevent them from spreading outwards.

[0041] At the same time, start the suction fan 209. The suction fan 209 operates to generate suction, and this suction is transmitted to the inside of the spherical cover 102 and the concave cover 103 through the first dust suction pipe 204 and the second dust suction pipe 205 respectively, sucking the raw material dust inside the spherical cover 102 and the concave cover 103 into the collection bin 203. The filter cartridge 206 can intercept and filter the raw material dust, so that the raw material dust is retained inside the collection bin 203 to achieve dust collection. During this process, part of the dust will adhere to the surface of the filter cartridge 206.

[0042] In order to prevent the filter cartridge 206 from being blocked due to excessive dust adhesion, the drive motor 210 can be started synchronously. The drive motor 210 drives the transmission gear 207 to rotate through the driving gear 211, and the transmission gear 207 drives the filter cartridge 206 to rotate. In this way, a relative displacement occurs between the filter cartridge 206 and the scraper 214, and the scraper 214 can scrape the wall of the rotating surface of the filter cartridge 206, so that the dust adhering to the surface of the filter cartridge 206 is scraped off, thereby preventing the filter cartridge 206 from being blocked.

[0043] Please refer specifically to Figures 1 to 4 , the sector baffle 213 and the scraper 214 are distributed on the same side of the filter cartridge 206, and the scraper 214 is symmetrically distributed with the openings of the first dust suction pipe 204 and the second dust suction pipe 205;

[0044] The sector angle of the sector baffle 213 is greater than the distribution angle of two adjacent partition plates 208, and the bottom of the filter cartridge 206 is of a closed structure.

[0045] In this embodiment: During the rotation of the filter cartridge 206 driven by the drive motor 210, the internal ventilation chamber at the contact position between the filter cartridge 206 and the scraper 214 is located below the sector baffle 213, that is, there is no suction inside the ventilation chamber at this part. In this way, the dust outside the filter cartridge 206 can be scraped off better, improving the effect of dust cleaning.

[0046] At the same time, the ventilation chambers close to the first suction pipe 204 and the second suction pipe 205 still maintain a good ventilation state, and thus the dust suction operation will not be affected.

[0047] Please refer specifically to Figures 1 to 4 , a discharge valve communicating with the collection bin 203 is installed at the bottom of the dust suction bucket 201, and the bottom end of the discharge valve is close to the upper surface of the lower conveyor belt.

[0048] In this embodiment: It should be added that: An observation port can be provided outside the dust suction bucket 201 to facilitate observing the dust collection situation inside the dust suction bucket 201. When there is a large amount of dust collected, the discharge valve can be opened to discharge the dust onto the lower conveyor belt. By controlling the size of the valve opening of the discharge valve, the dust discharge speed can be kept slow. In addition, since the bottom end of the discharge valve is close to the upper surface of the lower conveyor belt, the discharge drop of the powder is small, thus avoiding excessive dust generation during discharging.

[0049] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
