Description

Technical Field

[0001] This utility model relates to the technical field of cement feeding devices, specifically to an anti-clogging feeding trough structure for cement production. Background Technology

[0002] In the cement production process, various materials such as coal briquettes and clinker need to be transported, which requires the use of feed chutes. Feed chutes are key equipment connecting different process stages. Their main function is to guide, control, and regulate the stable and smooth flow of materials (such as raw materials, raw meal, clinker, coal powder, cement, etc.) from one equipment or silo into the next equipment or conveying system. They play a "throat" role in the entire production process, and their design and operation directly affect the continuity, efficiency, energy consumption, safety, and environmental protection of production.

[0003] The existing technology has the following shortcomings: Application number 202022322484.5 proposes a cement production feeding trough device with a simple structure and improved wear resistance. This cement production feeding trough device includes a base on which a feeding trough is installed. The feeding trough is a square formed by welding four steel plates sequentially, and wear-resistant liners are provided at the bottom and on both sides inside the feeding trough. The cement production feeding trough device of this utility model, through the cooperation of the base, feeding trough, and liners, facilitates the installation of the feeding trough. Furthermore, the liner improves wear resistance and extends service life. In addition, the square shape reduces the contact area, further reducing wear. Therefore, it features a simple structure and improved wear resistance.

[0004] The aforementioned equipment does not have an anti-clogging effect. When the material conveying volume is large or the material particles are large, blockage is easily caused, which directly affects the material conveying. In addition, the blocked discharge chute can only be handled manually, which is cumbersome and cannot achieve an anti-clogging effect on its own. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-clogging feed trough structure for cement production, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement production anti-clogging feeding trough structure, comprising a main body, flanges at both ends of the main body, a first mounting plate on the outer side of the main body, an air inlet pipe on the first mounting plate, a second mounting plate on the outer side of the main body, a sealing plate on the outer side of the second mounting plate, a transfer cavity in the first mounting plate, a connecting hole in the transfer cavity, a stepped feeding cavity in the main body, a side step in the stepped feeding cavity, an exhaust hole in the side step, an annular cavity in the main body, an installation cavity in the second mounting plate, a small motor in the installation cavity, an eccentric block at the output end of the small motor, and a rubber component at the port of the exhaust hole;

[0007] The enclosed plate includes a hinge, an insert, and a strong magnet. The hinge is provided on one side of the enclosed plate, and the strong magnet is provided inside the insert.

[0008] As a preferred technical solution of this utility model: there are three sets of the second mounting plate with the same structure. The first mounting plate, the second mounting plate and the main body are all integrally formed. The air intake pipe is fixedly installed on the outside of the first mounting plate. One end of the air intake pipe is connected to the output end of the external air pump, and the other end of the air intake pipe is connected to the transfer chamber.

[0009] As a preferred technical solution of this utility model: the small motor is fixedly installed in the mounting cavity, the eccentric block is fixedly installed at the output end of the small motor, and there are three sets of small motors connected in series and connected to an external power source.

[0010] As a preferred technical solution of this utility model: one side of the hinge is fixed to one end of the closed plate by bolts, and the other side of the hinge is fixed to the outside of the second mounting plate by bolts, and the closed plate corresponds to the mounting cavity.

[0011] As a preferred technical solution of this utility model: the strong magnet is fixedly embedded in the embedding hole, and an iron block is embedded on the outer side of the second mounting plate at the position corresponding to the strong magnet. The strong magnet and the iron block embedded on the second mounting plate are magnetically attracted to each other.

[0012] As a preferred technical solution of this utility model: the transfer cavity, the connecting hole, the annular cavity, and the exhaust hole are interconnected. There are six sets of side steps and six sets of annular cavities, each corresponding to one set of side steps.

[0013] As a preferred technical solution of this utility model: the rubber component is specifically composed of four sets of fan-shaped rubber preforms, and the rubber component is adapted to and fixedly installed in the exhaust hole.

[0014] Compared with the prior art, this utility model provides a structure for an anti-clogging feed trough for cement production, which has the following advantages:

[0015] 1. This anti-clogging feeding trough structure for cement production includes an air inlet pipe, a transfer chamber, a connecting hole, a stepped feeding chamber, side steps, an exhaust hole, an annular cavity, a small motor, an eccentric block, and rubber parts. The output end of an external air pump is connected to the air inlet pipe, and the small motor is connected to an external power source. The air pump generates airflow that passes sequentially through the air inlet pipe, the transfer chamber, the connecting hole, and the annular cavity. Finally, the airflow pushes open the rubber parts and is discharged from the exhaust hole into the stepped feeding chamber. The airflow flows along the inner wall of the stepped feeding chamber, carrying the material close to the inner wall forward, thus achieving an anti-clogging effect. During the material conveying process, the small motor drives the eccentric block to rotate, generating vibration that causes the entire main body to vibrate. The material conveyed inside the stepped feeding chamber is affected by the vibration, preventing accumulation and further improving the anti-clogging effect.

[0016] 2. This anti-clogging feeding trough structure for cement production is equipped with an exhaust port, an annular cavity, a small motor, and an eccentric block. The air pump output gas is finally discharged from the exhaust port, and the vibration generated by the operation of the small motor is also automatically carried out. It can prevent feeding blockage without manual intervention. If a blockage occurs by accident, it can be cleared automatically, thus achieving an anti-clogging effect. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 In this embodiment: a cement production anti-clogging feeding trough structure includes a main body 1, flanges 2 at both ends of the main body 1, a first mounting plate 3 on the outside of the main body 1, an air inlet pipe 4 on the first mounting plate 3, a second mounting plate 5 on the outside of the main body 1, a sealing plate 6 on the outside of the second mounting plate 5, a transfer cavity 7 in the first mounting plate 3, a connecting hole 8 in the transfer cavity 7, a stepped feeding cavity 9 in the main body 1, a side step 10 in the stepped feeding cavity 9, an exhaust hole 11 in the side step 10, an annular cavity 12 in the main body 1, an installation cavity 13 in the second mounting plate 5, a small motor 14 in the installation cavity 13, an eccentric block 15 at the output end of the small motor 14, and a rubber part 16 at the port of the exhaust hole 11.

[0025] The flange 2 facilitates the installation of the main body 1, the air inlet pipe 4 facilitates the connection to the output end of the external air pump, and the sealing plate 6 can seal the mounting cavity 13 to prevent external dust from affecting the interior of the mounting cavity 13.

[0026] The enclosed plate 6 includes a hinge 601, an insertion port 602, and a strong magnet 603. The hinge 601 is provided on one side of the enclosed plate 6, and the strong magnet 603 is provided in the insertion port 602.

[0027] The hinge 601 allows the enclosed plate 6 to be easily flipped, and the strong magnet 603 can generate magnetic attraction between it and the iron block embedded in the second mounting plate 5, ensuring the stability of the enclosed plate 6.

[0028] In this embodiment, there are three sets of second mounting plates 5 with identical structures. The first mounting plate 3, the second mounting plate 5 and the main body 1 are all integrally formed. The air intake pipe 4 is fixedly installed on the outside of the first mounting plate 3. One end of the air intake pipe 4 is connected to the output end of an external air pump, and the other end of the air intake pipe 4 is connected to the transfer chamber 7. The small motor 14 is fixedly installed in the mounting chamber 13. The eccentric block 15 is fixedly installed on the output end of the small motor 14. There are three sets of small motors 14 connected in series and connected to an external power source. One side of the hinge 601 is fixed to one end of the closed plate 6 by bolts, and the other side of the hinge 601 is fixedly installed on the outside of the second mounting plate 5 by bolts. The closed plate 6 corresponds to the mounting chamber 13.

[0029] Specifically, airflow can be evenly input into the six annular cavities 12 through the transfer cavity 7 and the connecting hole 8. The main body 1 can be driven to vibrate through the small motor 14 and the eccentric block 15. The material conveyed inside the stepped feeding cavity 9 will be affected by the vibration to avoid accumulation. The small motor 14 can be easily installed through the mounting cavity 13.

[0030] In this embodiment, the strong magnet 603 is fixedly embedded in the embedding port 602. An iron block is embedded on the outer side of the second mounting plate 5 at the position corresponding to the strong magnet 603. The strong magnet 603 and the iron block embedded on the second mounting plate 5 are magnetically attracted. The transfer cavity 7, the connecting hole 8, the annular cavity 12, and the exhaust hole 11 are interconnected. There are six sets of side steps 10 and six sets of annular cavities 12, each corresponding to one set of side steps 10. Each set of side steps 10 has an exhaust hole 11 in an annular shape and communicates with the corresponding annular cavity 12. The rubber part 16 is specifically composed of four sets of fan-shaped rubber preforms. The rubber part 16 is adapted to the exhaust hole 11 and fixedly installed in the exhaust hole 11.

[0031] Specifically, the annular cavity 12 facilitates the uniform input of airflow into the exhaust port 11. When the airflow rushes out of the exhaust port 11 through the rubber component 16, it will be pushed open by the airflow pressure to ensure that the airflow is discharged smoothly from the exhaust port 11. When no airflow passes through the exhaust port 11, the rubber component 16 will close the exhaust port 11 to prevent the conveyed material from entering the exhaust port 11.

[0032] The working principle and usage process of this utility model are as follows: In actual use, the equipment is placed in a suitable position and connected to the corresponding position of the cement production conveying system through the flanges 2 at both ends. The flanges 2 are fixed with matching bolts, and the output end of the external air pump is connected to the air inlet pipe 4. The three sets of small motors 14 connected in series are connected to an external power supply. When the conveyed material passes through the stepped discharge chamber 9, it will contact the inner wall of the stepped discharge chamber 9. The external air pump is started to generate airflow. The airflow is input into the transfer chamber 7 through the air inlet pipe 4 and enters the annular chamber 12 through the connecting hole 8. Finally, the airflow is discharged from the annular chamber 12 through the exhaust hole 11 into the stepped discharge chamber 9. The airflow will flow along the inner wall of the stepped discharge chamber 9, carrying the material close to the inner wall of the stepped discharge chamber 9 forward, so that the material will not accumulate in the stepped discharge chamber 9, thus achieving anti-blocking. The anti-blocking effect is achieved when the airflow rushes out of the exhaust port 11, it pushes open the rubber part 16 under the action of airflow pressure, ensuring that the airflow can be discharged smoothly from the exhaust port 11. When no airflow passes through the exhaust port 11, the rubber part 16 will close the exhaust port 11 to prevent the conveyed material from entering the exhaust port 11. During the material conveying process, the small motor 14 is started to drive the eccentric block 15 to rotate. Under the action of the eccentric block 15, the small motor 14 will generate vibration, thereby driving the main body 1 to vibrate as a whole. The material conveyed inside the stepped feeding chamber 9 will be affected by the vibration, avoiding accumulation and further improving the anti-blocking effect. The air pump output gas is finally discharged from the exhaust port 11 and the vibration generated by the operation of the small motor 14 are both carried out automatically. Material blockage can be prevented without manual intervention. If a blockage occurs by accident, it can be cleared automatically, and the anti-blocking effect can be achieved automatically.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
