Description

Technical Field

[0001] This utility model relates to the field of cement production, and in particular to a coal powder silo anti-blocking and pressure-reducing cone device. Background Technology

[0002] A search of Chinese patents revealed publication number CN219858636U, which discloses a pressure-reducing cone device for a powder storage silo. The device includes a silo body with conical bottom support plates on both sides of the inner wall. A pressure-reducing cap support plate is located on the top surface of the conical bottom support plate, and a pressure-reducing cap is located on the top surface of the pressure-reducing cap support plate. Legs are located on both sides of the silo body, and a storage plate is located between the legs. A conveying cylinder is located on the top surface of the storage plate. This invention, through the use of the pressure-reducing cap, pressure-reducing cap support plate, and conical bottom support plate, cleverly utilizes the mechanical properties of the conical bottom to effectively solve the problem of poor material flow due to excessive pressure and density at the bottom, while maintaining low cost. This ensures uniform and stable material flow, prevents blockages during material flow, and only optimizes the internal structure of the silo, without increasing installation space. Furthermore, it eliminates the need for regular manual cleaning and tapping, thus saving costs.

[0003] Existing pressure-reducing cone devices cannot adjust the position of the pressure-reducing cone. Generally, the pressure-reducing cone is fixedly installed inside the coal powder silo, resulting in a fixed gap between the pressure-reducing cone and the inner wall of the silo. Since coal powder has different particle sizes, different particle sizes require different gap distances to ensure normal discharge. Therefore, when using coal powder of different particle sizes, if the gap between the pressure-reducing cone and the inner wall of the silo is too small, it may restrict the flow space of the material, leading to poor material flow. If the gap is too large, it may generate excessive turbulence and eddies during the material flow process, affecting the stability and continuity of the material. An excessively large gap may also weaken the flow guiding effect of the pressure-reducing cone, reducing its pressure-reducing effect and practicality. It also prevents the surface of the pressure-reducing cone from being cleaned. During the use of the pressure-reducing cone, if the moisture content of the coal powder is too high, the coal powder will stick to the surface of the pressure-reducing cone when in contact with it, thereby increasing the resistance of the pressure-reducing cone, affecting the flowability of the coal powder, increasing the risk of blockage and the amount of maintenance required later, and making it inconvenient to use. To solve the above problems, we propose a coal powder silo anti-clogging pressure-reducing cone device. Utility Model Content

[0004] The purpose of this invention is to provide a coal powder silo anti-clogging pressure reducing cone device, which has the advantages of being able to adjust the position of the pressure reducing cone and clean the surface of the pressure reducing cone.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a coal powder silo anti-blocking and pressure-reducing cone device, comprising a coal powder silo, a fixed frame bolted between the inner walls of the coal powder silo, a screw rotatably sleeved on the inner wall of the fixed frame, a base plate threadedly connected to the surface of the screw, a pressure-reducing cone bolted to the top of the base plate, a guide rod bolted to the top of the fixed frame, and the guide rod slidably sleeved with the inner wall of the base plate, a first bevel gear fixedly sleeved at the bottom of the screw, a second bevel gear meshing with the surface of the first bevel gear, a rotating shaft fixedly sleeved at the axis of the second bevel gear, and the rotating shaft rotatably sleeved with the inner wall of the coal powder silo.

[0006] By adopting the above technical solution, the rotating turntable drives the rotating shaft to rotate, which in turn drives the screw to rotate. The rotation of the screw causes the bottom plate to move the pressure reducing cone, thereby changing the distance between the pressure reducing cone and the inner wall of the pulverized coal silo. This achieves the purpose of adjusting the position of the pressure reducing cone, ensuring smooth and stable material discharge, and improving applicability and practicality.

[0007] The present invention is further configured such that: a motor is bolted to the inner wall of the pressure reducing cone, the output end of the motor passes through the pressure reducing cone and is fixedly sleeved with a conical block, and a rotating plate is bolted to the surface of the conical block.

[0008] By adopting the above technical solution, the conical block is driven to rotate by the rotation of the motor, and the rotating plate is driven to rotate to clean the surface of the pressure reducing cone. This method can achieve the purpose of cleaning the pressure reducing cone, ensure the cleanliness of the pressure reducing cone, improve the stability of material discharge, and reduce the risk of blockage.

[0009] The present invention is further configured such that a rotating disk is bolted to one end of the rotating shaft.

[0010] By adopting the above technical solution, a rotating disk is set up to facilitate the rotation of the shaft.

[0011] The present invention is further configured such that a limit block is bolted to the top of both the guide rod and the screw.

[0012] By adopting the above technical solution, a limit block is set to prevent the pressure relief cone from slipping out, thus ensuring stability.

[0013] The present invention is further configured such that: the number of rotating plates is four, and the four rotating plates are evenly distributed on the surface of the conical block.

[0014] By adopting the above technical solution, and by setting the number of rotating plates to four, and having the four rotating plates evenly distributed on the surface of the conical block, the cleaning efficiency is improved.

[0015] The present invention is further configured such that a rubber pad is embedded in the surface of the rotating plate.

[0016] By adopting the above technical solution, rubber pads are installed to prevent damage to the pressure-reducing cone and improve its service life.

[0017] The present invention is further configured such that: a fixing shell is bolted to the bottom of the fixing frame, and the fixing shell is rotatably sleeved with the surface of the rotating shaft.

[0018] By adopting the above technical solution, a fixed shell is set up to protect the first and second bevel gears and fix the rotating shaft, thereby improving stability.

[0019] The present invention is further configured such that a filter screen is bolted between the inner walls of the base plate.

[0020] By adopting the above technical solution and setting up a filter screen, the heat dissipation efficiency of the motor can be improved.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model achieves the purpose of adjusting the position of the pressure reducing cone by rotating the turntable to drive the rotating shaft to rotate the screw, and the rotation of the screw to drive the base plate to move the pressure reducing cone, thereby changing the distance between the pressure reducing cone and the inner wall of the coal powder silo. This ensures smooth and stable material discharge and improves applicability and practicality.

[0023] 2. This utility model uses a motor to drive a conical block to rotate, which in turn drives a rotating plate to clean the surface of the pressure-reducing cone. This achieves the purpose of cleaning the pressure-reducing cone, ensuring its cleanliness, improving the stability of material output, and reducing the risk of blockage. Attached Figure Description
