Description

Technical Field

[0001] This invention relates to the field of flux processing technology, and more specifically to a circulating pulverizing device for processing powdered fluxes. Background Technology

[0002] Within the industry, increasing the gasification temperature of gasifiers can lead to problems such as increased corrosion and greater difficulty in heat preservation. To effectively reduce the operating temperature of gasifiers, powdered flux can be added to lower the ash melting point of coal.

[0003] In the production and processing of powdered fluxes, they generally need to be processed into powder using crushing equipment. However, existing crushing equipment structures have the following problems: To ensure timely discharge of powdered material during processing, a bottom-mounted filter is typically used, with the crushed material collected through the filter holes. However, this structure suffers from the following issues: the filter holes are prone to clogging, and even scraping the filter holes with material is difficult to clear the blockage. Therefore, regular cleaning of the filter plates is necessary.

[0021] Beneficial effects

[0022] This invention allows materials to enter through a feed pipe. The flux is processed into powder by a crushing component. An anti-overflow blower component blows the powdered flux to prevent it from leaking to the outside. The powdered flux is blown to a synchronous filter component above, where it is filtered. The synchronous filter component can also automatically circulate and clean its filter holes, scraping off large particles and letting them fall back down, thus preventing clogging. Small particles of powdered flux pass through the synchronous filter component and enter the discharge pipe for discharge and collection.

[0023] This invention utilizes an upper discharge design to blow out small-particle powdered flux through a filter. Larger particles can fall back onto the crushing assembly for further crushing while the filter holes are being cleaned. In contrast to the lower-positioned filter design where the crushing structure directly contacts the filter holes, the synchronous filtration assembly does not contact the crushing assembly, making it less likely for large particles to clog the synchronous filtration assembly. Powdered flux that meets the particle size requirements can be discharged promptly and effectively. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The present invention will be further described below with reference to embodiments.

[0037] Example 1

[0038] Please refer to the instruction manual appendix. Figure 1 A circulating crushing device for processing powdered flux includes a base 1, on which a crushing component 2 for processing flux into powder is installed;

[0039] An anti-overflow blower assembly 3 is installed on the base 1 to blow up the powdered flux and prevent the powdered flux from leaking into the outside.

[0040] A feed pipe 4 for feeding is fixedly connected to the crushing assembly 2; a top cover 5 is fixedly installed on the top of the crushing assembly 2, and a discharge pipe 6 for discharging is fixedly connected to the top of the top cover 5.

[0041] The top cover 5 is equipped with a synchronous filter assembly 7 for filtering the blown powdered flux and for automatically circulating and cleaning the filter holes. The synchronous filter assembly 7 is connected to the discharge pipe 6.

[0042] The crushing assembly 2 is equipped with a material feeding assembly 8 for scraping and dispersing materials.

[0043] In this invention, materials are fed into the feed pipe 4, and the flux is processed into powder by the crushing component 2. The powdered flux is blown up by the anti-overflow blower component 3 to prevent it from leaking to the outside. The powdered flux is blown up to the synchronous filter component 7 above, where it is filtered. The synchronous filter component 7 can also automatically circulate and clean the filter holes, scraping off large particles and letting them fall back down, thus preventing the synchronous filter component 7 from becoming clogged. Small particles of powdered flux pass through the synchronous filter component 7 and enter the discharge pipe 6 for discharge and collection.

[0044] This invention utilizes a top-discharge design to allow small-particle powdered flux to be filtered and discharged via air filtration. Larger particles can fall back onto the crushing component 2 for further crushing under gravity while the filter holes are being cleaned, thus achieving material recycling and crushing. Furthermore, unlike the bottom-discharge filter method where the crushing structure directly contacts the filter holes, the synchronous filter component 7 does not contact the crushing component 2. Large particles are less likely to clog the synchronous filter component 7, and powdered flux meeting particle size requirements can be discharged promptly and effectively, essentially eliminating the need for separate, periodic cleaning of the synchronous filter component 7.

[0045] Example 2

[0046] Based on Example 1, please refer to the appendix of the instruction manual. Figure 1-8 The crushing component 2 includes a rotating disc assembly and a crushing assembly; the rotating disc assembly and the crushing assembly are in active contact connection;

The connecting shaft 28 is fixedly connected to the output end of the reducer 22. The rotating seat 27 is fixedly connected to the top of the connecting shaft 28. The rotating seat 27 is in movable contact with the compaction assembly.

[0048] The first motor 21 drives the reducer 22 to rotate, the reducer 22 drives the connecting shaft 28 to rotate, and the connecting shaft 28 drives the rotating seat 27 to rotate.

[0049] The crushing assembly includes a second motor 23, a crushing wheel 26, a support frame 24, and a straight cylinder 25; the anti-overflow blower assembly 3 covers the outside of the connecting shaft 28 and the rotating seat 27; the straight cylinder 25 is fixedly installed on the upper end of the anti-overflow blower assembly 3; several sets of support frames 24 are fixedly connected at equal intervals on the outer side wall of the straight cylinder 25; the second motor 23 is fixedly installed on each support frame 24; the output end of the second motor 23 passes through the straight cylinder 25 in a sealed manner and is rotatably connected to the straight cylinder 25; the output end of the second motor 23 is fixedly connected to the crushing wheel 26; the lower end of the crushing wheel 26 is in contact with the crushing groove opened on the outer circumference of the rotating seat 27.

[0050] The feed pipe 4 is fixedly installed on the straight cylinder 25, and the outlet of the feed pipe 4 is located above the bottom of the rotating seat 27. The top of the rotating seat 27 is provided with a conical guide section.

[0051] The second motor 23 drives the crushing wheel 26 to rotate, and the crushing wheel 26 cooperates with the rotating seat 27 to crush and grind the material entering from the feed pipe 4.

[0052] The anti-overflow blower assembly 3 includes an annular cover 31, support legs 32, an air inlet pipe 33, a base plate 34, an inner annular plate 35, an outer annular plate 36, and an annular connecting plate 37. The annular cover 31 is fixedly installed on the upper end of the base 1 via several sets of support legs 32. The annular cover 31 covers the outside of the connecting shaft 28 and the rotating seat 27. A base plate 34 for sealing is fixedly connected inside the annular cover 31. The base plate 34 is located between the rotating seat 27 and the top of the reducer 22, and is rotatably connected to the connecting shaft 28. An air inlet pipe 33 is fixedly connected to the outer wall of the annular cover 31. The height of the air inlet pipe 33 is above the height of the base plate 34. The top is fixedly connected to the bottom of the straight cylinder 25.

[0053] The air is connected to an external air pump through the air inlet pipe 33. The gas enters the annular cover 31 through the air inlet pipe 33, and then enters the space between the annular inner plate 35 and the rotating seat 27 through the ventilation gap between the annular connecting plate 37 and the annular cover 31, the annular inner plate 35 and the annular outer plate 36. Then it enters the inside of the straight cylinder 25, blowing up the material that has been crushed into powder by the crushing wheel 26 on the rotating seat 27. At the same time, since the connection parts are all sealed, the powdered flux can be prevented from leaking to the outside.

[0054] Example 3

[0055] Based on Example 2, please refer to the appendix of the instruction manual. Figure 1-8 The inside of the straight cylinder 25 is equipped with several sets of feeding components 8;

[0056] The feeding assembly 8 includes a connecting block 81 and a second scraper 82; the lower end of the inner wall of the straight cylinder 25 is fixedly connected to the connecting block 81, and the second scraper 82 is fixedly installed on the connecting block 81. The bottom of the second scraper 82 is in contact with the upper end of the rotating seat 27.

[0057] The connecting block 81 is located above the annular outer plate 36, and the second scraper 82 is located inside the annular inner plate 35;

[0058] The length of the second scraper 82 is slightly smaller than the radius of the rotating seat 27;

[0059] When the rotating seat 27 rotates, the material on the rotating seat 27 is scraped up by the second scraper 82, which helps to remove the material stuck to the rotating seat 27 and improve the crushing effect; at the same time, it can also disperse the material, which helps the anti-overflow blower assembly 3 to lift the powdery material and blow it to the synchronous filter assembly 7.

[0060] The synchronous filtration assembly 7 includes a third motor 71, a first gear ring 72, a first bevel gear 73, a horizontal shaft 74, a second bevel gear 75, a second gear ring 76, an annular filter barrel 77, a first scraper 78, and a support bearing 79; a top cover 5 is fixedly connected to the top of the straight cylinder 25; a third motor 71 is fixedly installed on the top of the top cover 5, and a first gear ring 72 is fixedly connected to the output end of the third motor 71. The first gear ring 72 meshes with the second gear ring 76, and the second gear ring 76 is rotatably mounted on the upper inner wall of the top cover 5 through the support bearing 79. An annular second bevel gear 75 is fixedly connected to the bottom of the second gear ring 76.

[0061] Four sets of annular filter barrels 77 are rotatably installed on the inner wall of the top cover 5 at equal intervals along the radial direction of the top cover 5. One end of each annular filter barrel 77 is rotatably installed on the top cover 5 via a horizontal shaft 74, and the other end of each annular filter barrel 77 is rotatably connected to the lower side wall of the discharge pipe 6. Each annular filter barrel 77 is connected to the discharge pipe 6. A first bevel gear 73 is fixedly installed on each annular filter barrel 77, and the first bevel gear 73 and the second bevel gear 75 are meshed and connected.

[0062] Four sets of first scrapers 78 are fixedly installed on the inner wall of the top cover 5, and each first scraper 78 is in contact with the bottom of each annular filter barrel 77.

[0063] The third motor 71 drives the first gear ring 72 to rotate, the first gear ring 72 drives the second gear ring 76 to rotate, the second gear ring 76 drives the second bevel gear 75 to rotate, the second bevel gear 75 drives each set of first bevel gears 73 to rotate, and the first bevel gears 73 drive the annular filter barrel 77 to rotate. The annular filter barrel 77 filters the material. When the annular filter barrel 77 rotates, the surface of the annular filter barrel 77 is cleaned by the first scraper 78 to prevent the filter holes from clogging. Small particles of powdered flux are filtered and discharged, while large particles can fall back onto the crushing component 2 for crushing and processing under the action of gravity while the filter holes are being cleaned. At the same time, compared with the lower filter hole method where the crushing structure is in direct contact with the filter holes, the synchronous filter component 7 does not contact the crushing component 2, and large particles are less likely to clog the synchronous filter component 7. Powdered flux that meets the particle size requirements can be discharged in a timely and effective manner.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
