Description

Technical Field

[0001] This utility model relates to the field of chute feeding technology, and in particular to a feeding control component for a feeding chute. Background Technology

[0002] In the cement production process, from raw material blending to clinker calcination and cement grinding, each step has strict material ratio requirements to ensure uniform mixing of materials. Therefore, it is necessary to install a feeding control component in the feeding chute to control the amount of material fed to a certain extent.

[0003] In existing technologies, dividing rollers are typically installed in the feeding chute for feeding control. During use, the dividing rollers are driven by a motor to rotate in the feeding chute, thereby intermittently feeding materials and ensuring uniform material distribution. However, due to uneven material distribution, the materials often get stuck between the dividing rollers and the feeding chute, causing jamming and interrupting feeding, or increasing the power consumption of the motor. Therefore, based on the above situation, it is necessary to design a feeding control component for the feeding chute to solve the above problems. Utility Model Content

[0004] This utility model provides a feeding control component for a feeding chute to solve the problem of material jamming and feeding interruption caused by material feeding in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] The feeding control component of the feeding chute includes a feeding baffle, a feeding box, and a linkage assembly. The feeding baffle includes a rigid plate hinged to the inner wall of the chute body and an elastic plate disposed on the rigid plate. An elastic element is connected between the bottom of the rigid plate and the inner wall of the chute body. The elastic element provides an upward restoring force to the feeding baffle, so that the feeding baffle remains closed when no external force is applied. The output end of the feeding box is connected to the chute body and is located above the feeding baffle. A sealing plate is slidably connected to the bottom of the feeding box. The linkage assembly is located between the sealing plate and the feeding baffle. When the feeding baffle swings, it controls the linkage assembly to drive the sealing plate to slide, thereby changing the size of the opening at the output end of the feeding box.

[0007] Preferably, the linkage component includes a linkage plate connected to the rigid plate and a limiting plate connected to the bottom of the sealing plate. A spring is connected between the sealing plate and the inner wall of the chute body. When the discharge baffle drives the linkage plate to swing downward, the linkage plate moves against the limiting plate, causing the sealing plate to slide and stretch the spring, thereby reducing the opening of the discharge box output end.

[0008] Preferably, the inner wall of the chute body is provided with a material distribution rack that disperses the material and causes it to fall onto the discharge baffle. The material distribution rack is inclined downward from the direction of the discharge baffle and is located between the discharge box and the discharge baffle.

[0009] Preferably, a first position seal is provided between the linkage plate and the inner wall of the chute body, and a second position seal is provided on the rigid plate.

[0010] Preferably, the elastic element includes an arc-shaped fixed tube connected to the bottom of the rigid plate and an arc-shaped movable rod connected to the inner wall of the chute body. Both the arc-shaped fixed tube and the arc-shaped movable rod are arc-shaped. One end of the arc-shaped movable rod is slidably connected to the inside of the arc-shaped fixed tube, and a spring is connected between the arc-shaped movable rod and the inner wall of the arc-shaped fixed tube.

[0011] Preferably, the elastic plate is detachably connected to the rigid plate.

[0012] The beneficial effects of this utility model are as follows: By feeding material from the feeding box, after a certain amount of material is fed, the feeding baffle swings to allow the material on it to fall. At the same time, the linkage component is controlled to drive the sealing plate to slide, making the opening at the output end of the feeding box smaller and reducing the amount of material falling onto the feeding baffle. After the material on the feeding baffle falls, because the material output from the feeding box is relatively small, the feeding baffle will move upward under the elastic action of the elastic element. At the same time, the linkage component is controlled to drive the sealing plate to slide, making the opening at the output end of the feeding box larger, and then the next round of intermittent feeding is carried out, avoiding the problem of material jamming and interruption of feeding.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-4 As shown, the feeding control component of the feeding chute includes a chute body 3, a feeding box 4 at the upper end of the chute body 3, and the output end of the feeding box 4 connected to the chute body 3. Material enters the interior of the chute body 3 through the output end of the feeding box 4. The component also includes a feeding baffle, which comprises a rigid plate 101 hinged to the inner wall of the chute body 3 and an elastic plate 102 detachably connected to the rigid plate 101. The elastic plate 102 can be made of rubber, silicone, or other materials and is fixed to the rigid plate 101 with screws for easy replacement. When material enters the interior of the chute body 3, it falls onto the rigid plate 101. When a certain amount of material falls, such as 10 kg, the weight of the material exceeds the supporting weight of the elastic element connecting the bottom of the rigid plate 101 to the inner wall of the chute body 3, causing the rigid plate 101 and the elastic plate 102 to swing down, opening the chute body 3 and allowing the material to be output from the output end of the chute body 3 into the next process. During the process, the feeding baffle simultaneously controls the linkage component located between the sealing plate 5 and the feeding baffle to drive the sealing plate 5, which is slidably connected to the bottom of the feeding box 4, to slide. This causes the sealing plate 5 to reduce the opening at the output end of the feeding box 4. At this time, the amount of material falling from the feeding box 4 is small, insufficient to cause the feeding baffle to continue swinging downward. Under the elastic action of the elastic element, the feeding baffle will be provided with an upward restoring force, so that the feeding baffle remains in the closed state of the chute body 3 when there is no external force, stopping the chute body 3 from continuing to feed. At the same time, the linkage component is controlled to drive the sealing plate 5 to slide, so that the opening at the output end of the feeding box 4 is enlarged, and then the next round of intermittent feeding can begin. At the same time, when the feeding baffle swings upward to reset, under the action of the elastic plate 102, even if there is blocky material stuck between the elastic plate 102 and the inner wall of the chute body 3, the elastic plate 102 will be deformed by force, preventing the material from getting stuck between the feeding baffle and the chute body 3, reducing the problem of material jamming during feeding and causing feeding interruption.

[0021] Reference Figure 1 , Figure 3 as well as Figure 4As shown, further, in order to realize the linkage between the feeding box 4 and the feeding baffle, the linkage component includes a linkage plate 601 connected to the rigid plate 101 and a limiting plate 602 connected to the bottom of the sealing plate 5. At the same time, a spring 7 is connected between the sealing plate 5 and the inner wall of the chute body 3. When the feeding baffle drives the linkage plate 601 to swing downward, the linkage plate 601 moves against the limiting plate 602, causing the sealing plate 5 to slide and drive the spring 7 to stretch, so that the opening of the feeding box 4 at the output end becomes smaller. When the feeding baffle returns to its original position upward, the sealing plate 5 returns to its original position under the elastic action of the spring 7. At this time, the opening of the feeding box 4 at the output end becomes larger, and normal feeding operation is carried out.

[0022] Reference Figure 1 , Figure 3 As shown, further, a material distribution frame 8 is provided on the inner wall of the chute body 3 to disperse the material and drop it onto the discharge baffle. The material distribution frame 8 is inclined downward from the direction of the discharge baffle and is located between the discharge box 4 and the discharge baffle. The material distribution frame 8 can be a through groove with a certain gap for the material to pass through. When the material in the discharge box 4 falls onto the material distribution frame 8, it can be dispersed and fall onto the discharge baffle, so that the material is evenly stressed at all positions of the discharge baffle, and the discharge baffle is not opened due to the large weight of the material falling instantaneously when the opening of the discharge end of the discharge box 4 is enlarged.

[0023] Reference Figure 1 , Figure 4 As shown, a first position seal 9 is provided between the linkage plate 601 and the inner wall of the chute body 3, and a second position seal 10 is provided on the rigid plate 101. Both the first position seal 9 and the second position seal 10 can be made of materials such as rubber or silicone. The first position seal 9 can be corrugated. When the discharge baffle drives the linkage plate 601 to move, the first position seal 9 can continuously seal the gap between the discharge baffle and the inner wall of the chute body 3, while the second position seal 10 can seal the gap between the rigid plate 101 and the inner wall of the chute body 3 to prevent material leakage.

[0024] Reference Figure 1As shown, the elastic element further includes an arc-shaped fixed tube 201 connected to the bottom of the rigid plate 101 and an arc-shaped movable rod 202 connected to the inner wall of the chute body 3. Both the arc-shaped fixed tube 201 and the arc-shaped movable rod 202 are arc-shaped. One end of the arc-shaped movable rod 202 is slidably connected to the inside of the arc-shaped fixed tube 201, and a spring 211 is connected between the arc-shaped movable rod 202 and the inner wall of the arc-shaped fixed tube 201. In use, when the discharge baffle swings downward, the discharge baffle drives the arc-shaped fixed tube 201 to slide towards the arc-shaped movable rod 202, and at the same time compresses the spring 211. After the material on the discharge baffle falls, under the elastic action of the spring 211, the arc-shaped fixed tube 201 and the discharge baffle are driven upward to return to their original positions, so that the discharge baffle remains closed to the chute body 3 when it is not subjected to external force.
