Description

Technical Field

[0001] The utility model relates to the field of conveying raw materials for cement production, in particular to an anti-blocking mechanism for conveying raw materials for cement production. Background Technique

[0002] Cement is a powdery hydraulic inorganic binder. After being mixed with water and stirred, it becomes a slurry, which can harden in the air or in water and can firmly cement materials such as sand and stone together. The early mixture of lime and volcanic ash was very similar to modern lime-volcanic ash cement. The concrete made by cementing gravel with it not only has high strength after hardening, but also can resist the erosion of fresh water or salt water.

[0003] In the process of cement production, the stable conveying of raw materials is a key link to ensure production efficiency and product quality. However, the traditional conveying system for raw materials in cement production often faces serious blockage problems.

[0004] During the production and processing of cement, mixing is required. After being mixed by a mixer, the cement needs to be conveyed to the next processing step through a conveyor belt. However, in actual production, the bottom discharge port of the mixer often becomes blocked, affecting normal feeding, which in turn causes the next processing step to be unable to process normally, affecting the conveying efficiency of the raw materials for cement production. For this reason, we propose an anti-blocking mechanism for conveying raw materials for cement production. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide an anti-blocking mechanism for conveying raw materials for cement production to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A cement production raw material conveying anti-blocking mechanism, including a cement production raw material tank, a sliding frame is slidably installed on the side wall of the cement production raw material tank, and a baffle is installed on the outer wall of the cement production raw material tank. A second chute is opened at the bottom of the sliding frame, and a fixed rod is fixedly installed inside the sliding frame. And a half gear meshing with the fixed rod is installed inside the sliding frame. The half gear is fixedly installed on the outer wall of the connecting rod. The connecting rod passes through and is fixedly installed on the first fixing block on the outer wall of the baffle. A pulley is fixedly installed at the bottom of the connecting rod, and a belt is rotatably installed on the outer wall of the pulley. A second motor is fixedly installed at the bottom end of the connecting rod. A conveyor belt is fixedly installed at the bottom end of the baffle. The second motor is fixedly installed on the support block on the outer wall of the conveyor belt frame. Baffles corresponding to the cement production raw material tank are fixedly installed at the top ends of the two side frames of the conveyor belt. And partitions are fixedly installed on the surface of the conveyor belt. And scrapers are slidably installed at the top ends of the two side frames of the conveyor belt. A limiting block is fixedly installed at the bottom end of the scraper. First chutes corresponding to the limiting block are opened at the ends of the two side frames of the conveyor belt. And a first motor is fixedly installed on the side wall of the conveyor belt frame. A bevel gear set is fixedly installed at the end of the first motor. The bevel gear set is fixedly installed on the outer wall of the reciprocating lead screw. A second fixing block is rotatably installed on the outer wall of the reciprocating lead screw far from the first motor. And the scraper is slidably installed on the outer wall of the reciprocating lead screw.

[0007] By adopting the above technical solution, when conveying the cement production raw materials, the scraper makes a reciprocating motion on the reciprocating lead screw, so that the scraper scrapes off the cement production raw materials accumulated on the conveyor belt, avoiding the accumulation of cement production raw materials. The sliding frame can disperse the accumulated raw materials when the cement production raw materials accumulate at the feeding port, avoiding blocking the feeding port and improving the conveying efficiency.

[0008] The present utility model is further arranged such that a plurality of groups of partitions are equidistantly installed on the surface of the conveyor belt, and the lengths of the plurality of groups of partitions correspond to the width of the conveyor belt, and the top ends of the plurality of groups of partitions are located on the same horizontal plane as the top ends of the two side frames of the conveyor belt.

[0009] By adopting the above technical solution, the partitions separate the cement production raw materials on the conveyor belt.

[0010] The present utility model is further arranged such that the sliding frame is designed to be inclined, and one end of the sliding frame inside the cement production raw material tank is lower than the end of the sliding frame outside the cement production raw material tank.

[0011] By adopting the above technical solution, when the sliding frame is used for ramming materials, the surface of the sliding frame will not accumulate cement production raw materials, and the cement production raw materials on the surface can fall off with the inclined design of the sliding frame.

[0012] The present utility model is further configured such that both ends of the fixed rod are fixedly installed on the corresponding inner walls of the sliding frame, and threads corresponding to the teeth of the semi-gear are provided on the outer wall of the fixed rod. The length of the second sliding groove corresponds to the length of the threads on the fixed rod, and the width of the second sliding groove corresponds to the diameter of the connecting rod.

[0013] By adopting the above technical solution, when the fixed rod slides, the sliding frame can be driven to slide, so that the semi-gear can rotate on the outer wall of the fixed rod.

[0014] The present utility model is further configured such that the cross-section of the scraping plate is designed in a V shape, and the opening of the V-shaped design faces the direction of the cement production raw material tank.

[0015] By adopting the above technical solution, when the V-shaped design makes the scraping plate contact the cement production raw materials, the cement production raw materials can be gathered towards the middle, avoiding overflow from both sides. Moreover, the opening of the V-shaped design faces the direction of the cement production raw material tank, which is opposite to the movement direction of the conveyor belt, thereby achieving the effect of scraping the materials.

[0016] The present utility model is further configured such that one side of the scraping plate close to the first motor is designed in an L shape, the bottom of the scraping plate is designed in a triangular shape, and the scraping plate is slidably connected to the two side frames of the conveyor belt.

[0017] By adopting the above technical solution, the first motor can drive the reciprocating screw rod to rotate. When conveying the cement production raw materials, the triangular design at the bottom of the scraping plate can be used to convey the cement production raw materials, avoiding the generation of gaps between the scraping plate and the two side frames of the conveyor belt when the scraping plate slides, and preventing the cement production raw materials from entering the gaps and affecting the sliding of the scraping plate.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] By providing a sliding frame and a scraping plate, when conveying the cement production raw materials, the scraping plate makes a reciprocating motion on the reciprocating screw rod, so that the scraping plate scrapes the cement production raw materials piled up on the conveyor belt, avoiding the accumulation of the cement production raw materials. When the cement production raw materials are piled up at the feeding port, the sliding frame can disperse the piled-up raw materials, avoiding the blockage of the feeding port and improving the conveying efficiency.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0028] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0029] A cement production raw material conveying anti-blocking mechanism, as Figure 1 - Figure 6As shown in the figure, it includes a raw material tank 1 for cement production. A sliding frame 8 is slidably installed on the side wall of the raw material tank 1 for cement production, and a baffle 2 is installed on the outer wall of the raw material tank 1 for cement production. A second chute 81 is opened at the bottom of the sliding frame 8, and a fixed rod 82 is fixedly installed inside the sliding frame 8. And a semi-gear 83 meshing with the fixed rod 82 is installed inside the sliding frame 8. The semi-gear 83 is fixedly installed on the outer wall of the connecting rod 10. The connecting rod 10 penetrates through and is fixedly installed on the first fixing block 9 on the outer wall of the baffle 2. A pulley 12 is fixedly installed at the bottom of the connecting rod 10, and a belt 11 is rotatably installed on the outer wall of the pulley 12. A second motor 13 is fixedly installed at the bottom end of the connecting rod 10. A conveyor belt 3 is fixedly installed at the bottom end of the baffle 2. The second motor 13 is fixedly installed on the support block 14 on the outer wall of the frame of the conveyor belt 3. At the top ends of the two side frames of the conveyor belt 3, baffles 2 corresponding to the raw material tank 1 for cement production are fixedly installed. And partition plates 31 are fixedly installed on the surface of the conveyor belt 3. And scraping plates 7 are slidably installed at the top ends of the two side frames of the conveyor belt 3. A limiting block 71 is fixedly installed at the bottom end of the scraping plate 7. First chutes 32 corresponding to the limiting block 71 are opened at the ends of the two side frames of the conveyor belt 3. And a first motor 4 is fixedly installed on the side wall of the frame of the conveyor belt 3. A bevel gear set 5 is fixedly installed at the end of the first motor 4. The bevel gear set 5 is fixedly installed on the outer wall of the reciprocating lead screw 6. The outer wall of the end of the reciprocating lead screw 6 far from the first motor 4 is rotatably installed on a second fixing block 33. And the scraping plate 7 is slidably installed on the outer wall of the reciprocating lead screw 6.

[0030] Please refer to Figure 1 and Figure 2 , multiple groups of partition plates 31 are equidistantly installed on the surface of the conveyor belt 3. The partition plates 31 separate the raw materials for cement production on the conveyor belt 3. And the lengths of the multiple groups of partition plates 31 correspond to the width of the conveyor belt 3. And the tops of the multiple groups of partition plates 31 are at the same horizontal plane as the top ends of the two side frames of the conveyor belt 3.

[0031] Please refer to Figure 3 , the sliding frame 8 is designed to be inclined, and the end of the sliding frame 8 inside the raw material tank 1 for cement production is lower than the end of the sliding frame 8 outside the raw material tank 1 for cement production. So that when the sliding frame 8 is ramming the materials, the surface of the sliding frame 8 will not accumulate the raw materials for cement production, and the raw materials on the surface can fall off with the inclined design of the sliding frame 8.

[0032] Please refer to Figure 4 and Figure 5 , both ends of the fixed rod 82 are fixedly installed on the corresponding inner walls of the sliding frame 8. When the fixed rod 82 slides, it can drive the sliding frame 8 to slide. And threads corresponding to the teeth of the semi-gear 83 are opened on the outer wall of the fixed rod 82, so that the semi-gear 83 can rotate on the outer wall of the fixed rod 82. The length of the second chute 81 corresponds to the length of the thread on the fixed rod 82, and the width of the second chute 81 corresponds to the diameter of the connecting rod 10.

[0033] Please refer toFigure 2 and Figure 6 , the cross-section of the scraper 7 is designed in a V shape, and the opening of the V-shaped design faces the cement production raw material tank 1. The V-shaped design enables the scraper 7 to gather the cement production raw materials towards the middle when contacting the cement production raw materials, avoiding overflow from both sides. Moreover, the opening of the V-shaped design faces the cement production raw material tank 1, which is opposite to the movement direction of the conveyor belt 3, thus achieving the function of scraping materials.

[0034] Please refer to Figure 1 - Figure 6 , one side of the scraper 7 close to the first motor 4 is designed in an L shape, enabling the first motor 4 to drive the reciprocating lead screw 6 to rotate. The bottom of the scraper 7 is designed in a triangular shape, and the triangular design at the bottom of the scraper 7 can be used to convey the cement production raw materials when conveying the cement production raw materials. The scraper 7 is slidably connected to the two side frames of the conveyor belt 3, avoiding the generation of gaps between the scraper 7 and the two side frames of the conveyor belt 3 when the scraper 7 slides, and preventing the cement production raw materials from entering the gaps and affecting the sliding of the scraper 7.

[0035] The working principle of the present utility model is as follows: When conveying the cement production raw materials, at this time, the first motor 4 and the second motor 13 start working simultaneously, causing the sliding frame 8 and the scraper 7 to start working simultaneously. When the cement production raw materials start to be discharged from the cement production raw material tank 1, the second motor 13 drives the connecting rod 10 to start rotating, and at the same time, the pulley 12 at the bottom of the connecting rod 10 also starts rotating. At this time, the belt 11 starts rotating on the surface of the pulley 12, causing the other connecting rod 10 to rotate simultaneously. At this time, the semi-gear 83 fixedly installed on the outer wall of the connecting rod 10 rotates simultaneously with the connecting rod 10, driving the fixed rod 82 inside the sliding frame 8 to perform reciprocating motion, realizing the function of dispersing the cement production raw materials in the cement production raw material tank 1 and preventing the discharge port of the cement production raw material tank 1 from being blocked. At this time, due to the movement of the sliding frame 8, the discharging speed is faster than the transportation speed of the conveyor belt 3, resulting in easy accumulation of the falling materials on the conveyor belt 3 during the falling process. At this time, the bevel gear set 5 fixedly installed on the first motor 4 drives the reciprocating lead screw 6 to rotate, and the scraper 7 slidably connected to the reciprocating lead screw 6 slides on the top of the two side frames of the conveyor belt 3, spreading the cement production raw materials accumulated on the conveyor belt 3. Through the partition 31 on the conveyor belt 3, the cement production raw materials are separated, preventing the accumulation of the cement production raw materials on the conveyor belt 3, reducing the impact on the conveying rate, accelerating the conveying efficiency, and avoiding the danger of manual dredging during blockage.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
