Description

Technical Field

[0001] The present invention relates to the technical field of calcining furnaces, and particularly to a calcining furnace provided with anti-blocking feeding. Background Art

[0002] A calcining furnace is a thermal equipment that heat-treats carbon raw materials (such as coke, anthracite, etc.) at high temperatures to improve the performance of the raw materials. In order to prevent blockage at the feeding point, existing calcining furnaces usually perform pre-crushing treatment on the materials, thereby reducing subsequent feeding blockage and ensuring the smooth progress of production.

[0003] For example, a calcining furnace with good anti-blocking effect for metal smelting engineering, with the publication number CN219433794U, includes a bottom plate. The top of the bottom plate is fixedly connected with a calcining furnace body. Both sides of the top of the calcining furnace body are fixedly connected with a shell. The top of the shell is fixedly connected with a feed box. A blanking pipe is communicated between the bottom of the feed box and the calcining furnace body. The back of the inner cavity of the shell is fixedly connected with a first motor. The output end of the first motor is fixedly connected with a cam. The inner wall of the shell is fixedly connected with a telescopic rod. It solves the problem that the existing calcining furnace for metal smelting engineering has poor anti-blocking effect and is prone to blockage caused by materials adhering to the inner wall of the discharge pipe. However, after the device crushes the materials, it directly feeds the materials through the blanking pipe for processing. There will be some larger pieces in the materials that are not completely crushed. These larger pieces of materials may still cause blockage at the feeding port, and also reduce the subsequent calcining effect of the calcining furnace. And only by knocking to reduce the situation of materials adhering to the inner wall of the blanking pipe, it is difficult to completely clean some materials that adhere tightly, resulting in limitations in feeding.

[0004] Therefore, a calcining furnace with anti-blocking feeding is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a calcining furnace with anti-blocking feeding to solve the problems that the larger pieces remaining after material crushing may still cause blockage at the feeding port, reduce the subsequent calcining effect of the calcining furnace, and there is easy material residue on the inner wall of the feeding pipe.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: A crushing component is provided. The material is crushed by the first crushing roller and the second crushing roller. The crushed material falls on the screening plate and is screened by the screening plate. The convex blocks on the outer side of the rotating rod rotate and spread the material, facilitating the screening of the material. The two scraping plates intermittently scrape the top of the screening plate, and the material located in the middle position between the two scraping plates will always be pushed for screening, improving the screening efficiency and screening effect of the material, reducing the situation of blockage of larger - sized materials in subsequent input, and improving the calcination efficiency.

The rotating rod slides inside the side groove. The moving plate is used to seal the side groove. The rotating rod drives the main gears at both ends to move. The main gears cooperate with the toothed plates. When the moving sleeve moves to the left, the rotating rod and the main gears rotate clockwise. When the moving sleeve moves to the right, the rotating rod and the main gears rotate counterclockwise. The bumps on the outside of the rotating rod rotate and spread the materials, facilitating the screening of the materials. When the rotating rod rotates clockwise, the rotating rod squeezes the crossbars on both sides through the bumps, causing the left crossbar and the scraping plate to rise intermittently. The scraping plate drives the sliding rod to rise intermittently. The sliding rod stretches Spring 1. The right scraping plate descends intermittently and scrapes the surface of the screening plate. When the rotating rod rotates counterclockwise, the left scraping plate scrapes, facilitating the pushing and screening of the materials on the top of the screening plate. And with the intermittent scraping setting of the two scraping plates, the materials in the middle position between the two scraping plates will always be pushed and screened, improving the screening efficiency and screening effect of the materials, reducing the situation of blockage of larger pieces of materials in subsequent input, improving the calcination efficiency, solving the problem that the larger pieces remaining after the material crushing may still cause blockage at the feeding port and also reducing the subsequent calcination effect of the calciner.

The bottom end of the bottom rod 612 is fixedly installed with a rotating rod 613 through a bearing.

[0054] The installation cover 68 is located on the upper part outside the reciprocating lead screw 66. Symmetrically opened on both sides inside the installation cover 68 are limiting grooves 611, and the side blocks 610 are slidably connected to the limiting grooves 611. The rotating rod 613 is rotatably connected to the bottom rod 612.

[0055] Symmetrically fixed to the outside of the bottom rod 612 are connection blocks 614. A sliding rod 615 is slidably installed inside the connection blocks 614. The bottom end of the sliding rod 615 is fixedly connected to a scraping plate 617. A convex block 618 is fixedly connected to the outside of the rotating rod 613. A horizontal bar 619 is fixedly connected to one side of the scraping plate 617 close to the rotating rod 613.

[0056] The sliding rod 615 is slidably connected to the connecting block 614. A first spring 616 is sleeved on the outer side of the upper part of the sliding rod 615. The top end of the first spring 616 is fixedly connected to the upper end of the sliding rod 615, and the bottom end of the first spring 616 is fixedly connected to the top of the connecting block 614.

[0057] Side grooves 620 are formed on both sides of the front and back of the processing box 2. The rotating rod 613 is slidably connected to the side grooves 620. Main gears 621 are symmetrically and fixedly connected to both ends of the rotating rod 613. Moving plates 622 are symmetrically installed on the outer side of the rotating rod 613. The rotating rod 613 is rotatably installed with the moving plates 622. A limiting frame 623 is fixedly connected to the outside of the processing box 2. The moving plates 622 are slidably connected to the limiting frame 623. Tooth plates 624 are symmetrically and fixedly connected to both sides of the front and back of the processing box 2. The main gears 621 are meshed with the tooth plates 624.

[0058] The convex blocks 618 are uniformly arranged in an array. The side of the cross bar 619 close to the convex blocks 618 is arc-shaped. The moving plates 622 are located outside the processing box 2 and are attached to the outer surface of the processing box 2. The tooth plates 624 are located above the main gears 621.

[0059] Example 1: As Figures 1 - 9 and Figure 12 shown, the material is conveyed into the processing box 2 through the feeding pipe 3. The first motor 61 and the second motor 64 are started. The first motor 61 drives the first crushing roller 63 to rotate, and the second motor 64 drives the second crushing roller 65 to rotate. The material is crushed by the first crushing roller 63 and the second crushing roller 65, and the crushed material falls on the screening plate 8 and is screened by the screening plate 8.

[0060] The first motor 61 drives the reciprocating lead screw 66 to rotate through the belt transmission part 67. The limiting grooves 611 limit the side blocks 610 and the moving sleeves 69, so that the moving sleeves 69 move linearly back and forth. The moving sleeves 69 drive the bottom rods 612 and the rotating rods 613 to move. The rotating rods 613 slide inside the side grooves 620. The moving plates 622 are used to seal the side grooves 620. The rotating rods 613 drive the main gears 621 at both ends to move. The main gears 621 cooperate with the tooth plates 624, so that when the moving sleeves 69 move to the left, the rotating rods 613 and the main gears 621 rotate clockwise, and when the moving sleeves 69 move to the right, the rotating rods 613 and the main gears 621 rotate counterclockwise. The convex blocks 618 on the outer side of the rotating rods 613 rotate and spread the material, facilitating the screening of the material.

[0061] When the rotating rod 613 rotates clockwise, the rotating rod 613 squeezes the cross bars 619 on both sides through the bumps 618, causing the left cross bar 619 and the scraping plate 617 to intermittently rise. The scraping plate 617 drives the sliding rod 615 to intermittently rise, and the sliding rod 615 stretches the first spring 616. The right scraping plate 617 intermittently descends and scrapes the surface of the screening plate 8. When the rotating rod 613 rotates counterclockwise, the left scraping plate 617 scrapes, facilitating the pushing and screening of the materials on the top of the screening plate 8.

[0062] With the intermittent scraping arrangement of the two scraping plates 617, the materials in the middle position between the two scraping plates 617 will always be pushed and screened, improving the screening efficiency and effect of the materials, reducing the situation of blockage of larger pieces of materials in subsequent input, improving the calcination efficiency, solving the problem that the larger pieces remaining after the material is broken may still cause blockage at the feed inlet, and also reducing the subsequent calcination effect of the calciner.

[0063] A cleaning assembly 7 is arranged on the outer side of the feed pipe 5. The cleaning assembly 7 includes a slave gear 71 and a cam 72. The slave gear 71 is fixedly installed on the moving plate 622, and the cam 72 is fixedly installed with the slave gear 71. Side plates 76 are symmetrically and slidably installed on the outer side of the feed pipe 5. A third spring 77 is fixedly connected between the side plates 76 and the processing box 2. The cam 72 abuts against the side plates 76.

[0064] The slave gear 71 is located on the side of the moving plate 622 away from the processing box 2. The slave gear 71 is located below the main gear 621. The cam 72 is located on the side of the slave gear 71 away from the moving plate 622. Chutes 73 are symmetrically opened on the front and rear sides of the feed pipe 5. A second spring 75 is fixedly connected to the inner bottom surface of the chute 73.

[0065] The top end of the second spring 75 is fixedly connected with a sliding block 74. One end of the sliding block 74 is fixedly connected with the side plate 76, and the other end of the sliding block 74 is fixedly connected with an inner sleeve 78.

[0066] There are no less than three third springs 77. The inner sleeve 78 is located inside the feed pipe 5. The outer wall of the inner sleeve 78 fits with the inner wall of the feed pipe 5. The inner sleeve 78 is slidably connected with the feed pipe 5.

[0067] Embodiment 2: As Figures 9 - 11As shown in the figure, the rotating rod 613 is rotatably installed on the moving plate 622. When the rotating rod 613 moves, it will drive the moving plate 622 and the driven gear 71 to move. The main gear 621 drives the driven gear 71 to rotate self, and the driven gear 71 drives the cam 72 to rotate. The cam 72 abuts against the side plate 76. The third spring 77 is installed between the processing box 2 and the side plate 76. When the cam 72 rotates, it will drive the side plate 76 to move up and down reciprocally. The movement of the side plate 76 drives the sliding block 74 to move, and the sliding block 74 drives the inner sleeve 78 to move. The second spring 75 assists the sliding and reset of the sliding block 74, thereby realizing the up and down scraping of the inner sleeve 78, facilitating the scraping and cleaning of the residual materials on the inner wall of the feeding pipe 5. Moreover, the inner wall of the inner sleeve 78 is provided with an inclined surface, reducing the adhesion of the materials on the inner sleeve 78 and facilitating the full calcination processing of the materials.

[0068] Working principle: When using this device, first, as Figures 1 - 12 shown in the figure, the materials are transported to the processing box 2 through the feeding pipe 3. Start the first motor 61 and the second motor 64, and crush the materials through the first crushing roller 63 and the second crushing roller 65. The crushed materials fall on the screening plate 8. The first motor 61 drives the reciprocating lead screw 66 to rotate through the belt transmission part 67, so that the moving sleeve 69 moves linearly back and forth. The moving sleeve 69 drives the bottom rod 612 and the rotating rod 613 to move. The main gear 621 cooperates with the toothed plate 624, so that the rotating rod 613 and the main gear 621 rotate. The convex block 618 on the outer side of the rotating rod 613 spreads the materials rotationally. When the rotating rod 613 rotates clockwise, the scraping plate 617 on the right intermittently descends and scrapes the surface of the screening plate 8. When the rotating rod 613 rotates counterclockwise, the scraping plate 617 on the left scrapes, facilitating the pushing and screening of the materials on the top of the screening plate 8. The main gear 621 also drives the driven gear 71 to rotate self, and the driven gear 71 drives the cam 72 to rotate. When the cam 72 rotates, it will drive the side plate 76 to move up and down reciprocally. The movement of the side plate 76 drives the sliding block 74 to move, and the sliding block 74 drives the inner sleeve 78 to move. The second spring 75 assists the sliding and reset of the sliding block 74, thereby realizing the up and down scraping of the inner sleeve 78, facilitating the scraping and cleaning of the residual materials on the inner wall of the feeding pipe 5.
