Description

Technical Field

[0001] This utility model belongs to the field of cement processing technology, specifically relating to a feeding device for a cement raw material powder roller press. Background Technology

[0002] The feeding device of a roller press is an important component that introduces the material to be rolled between the two rollers for roller pressing and grinding.

[0003] The opening of the feed hopper in the existing feeding device is not adjustable or can be manually adjusted. The particle size of the material being pressed is different. After entering between the extrusion rollers, the larger particles are squeezed while the smaller particles are easily leaked out. During feeding, the raw materials are also prone to accumulate in the middle of the extrusion rollers, resulting in different wear rates between the middle and both ends of the extrusion rollers and reducing their service life. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a feeding device for a cement raw material powder roller press.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] A feeding device for a cement raw material powder roller press is characterized in that it includes a feeding box, a feeding baffle, a screen plate, and an adjusting device. The feeding baffle is installed on both sides below the feeding box via a rotating shaft. The screen plate is a double-layer screen plate, with the two layers of screen plates respectively installed on the feeding baffle on both sides. The adjusting device is installed on the outside of the feeding box and is connected to the feeding baffle via a hydraulic rod.

[0007] Furthermore, the bottom of the feed box has an inverted bucket-shaped opening, and the feed baffle is installed inside the bucket.

[0008] Furthermore, a connecting rod is provided on the outer side of the feed baffle shaft.

[0009] Furthermore, the screen plate is an arc-shaped screen plate, with support rollers evenly arranged below the screen plate, and a material distribution plate installed below the support rollers.

[0010] Furthermore, the adjusting device includes a motor, a hydraulic rod, and a slider. The power output end of the motor is connected to the slider, one end of the hydraulic rod is connected to the feed baffle, and the other end is connected to the slider.

[0011] According to the above technical solution, the beneficial effects of this utility model are as follows: This utility model uses a sieve plate to first screen and retain materials with large particle sizes in the raw materials. After the materials with small particle sizes fall and are crushed, the feed baffle opens, the mesh of the sieve plate becomes larger, and the materials with large particle sizes fall. The material distribution net below the sieve plate evenly disperses the raw materials onto the extrusion roller, thereby maximizing the utilization rate of the extrusion roller.

[0016] To more clearly illustrate the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] See Figure 1-2 A feeding device for a cement raw material powder roller press is characterized by comprising a feeding box 1, a feeding baffle 2, a sieve plate 3, and an adjusting device 4. The feeding baffle 2 is installed on both sides below the feeding box 1 via a rotating shaft. The sieve plate 3 is a double-layer sieve plate, with the two layers of sieve plate 3 respectively installed on the feeding baffle 2 on both sides. The adjusting device 4 is installed on the outside of the feeding box 1 and is connected to the feeding baffle 2 via a hydraulic rod 42. The double-layer sieve plate 3 is used to screen raw materials of different particle sizes, so that the raw materials can be fed according to the particle size, thereby improving the extrusion efficiency of the roller press.

[0018] See Figure 1-2 The bottom of the feed box 1 has an inverted bucket-shaped opening, and the feed baffle 2 is installed inside the bucket. The inner wall of the bottom of the bucket-shaped feed box 1 can concentrate the raw materials into the middle of the feed baffle 2, avoiding the accumulation of raw materials in the dead corner at the bottom of the feed box 1.

[0019] See Figure 1-2 A connecting rod 21 is provided on the outer side of the rotating shaft of the feed baffle 2. One end of the connecting rod 21 is connected to the rotating shaft, and the other end is connected to the hydraulic rod 42. The rotation of the connecting rod 21 drives the feed baffle 2 to open and close, so that the feed amount can be adjusted when feeding the roller press.

[0020] See Figure 1-2 The screen plate 3 is an arc-shaped screen plate. Support rollers 31 are evenly arranged below the screen plate 3. A distribution plate 32 is installed below the support rollers 31. The double-layer screen plate 3 moves with the opening and closing of the feed baffles 2 on both sides, and the sieve aperture also changes accordingly, so that the raw materials can be fed according to the particle size. The distribution plate 32 is set to evenly disperse the falling raw materials on the axial direction of the roller press, so as to avoid the raw materials from concentrating in the middle of the extrusion rollers, which would affect the crushing efficiency and the service life of the equipment.

[0021] See Figure 1-2The adjusting device 4 includes a motor 41, a hydraulic rod 42, and a slider 43. The power output end of the motor 41 is connected to the slider 43. One end of the hydraulic rod 42 is connected to the feed baffle 2, and the other end is connected to the slider 43. The power output end of the motor 41 rotates inside the slider 43, driving the slider 43 to lift, pulling the feed baffle 2, and controlling the opening of the feeding inlet.

[0022] According to the above embodiments, the working process of this utility model is as follows:

[0023] Raw materials are fed into the feed box 1 and fall onto the screen plate 3 below. Larger particles are intercepted by the double-layer screen plate 3, while smaller particles fall into the roller press for crushing. The distribution plate 32 below the screen plate 3 evenly distributes the raw materials onto the extrusion rollers, preventing them from concentrating in the middle of the rollers and affecting crushing efficiency and equipment lifespan. As smaller particles gradually fall, the motor 41 is started. The screw of the motor 41 extends into the slider 43 and rotates, causing the hydraulic rod 42 to push the feed baffle 2. The opening of the feed baffle 2 increases, and the feed baffles on both sides pull the mesh of the screen plate 3 to increase, allowing larger particles to gradually fall into the roller press for crushing.

[0024] The above-disclosed embodiments of the present invention are only for illustrating the present invention. The preferred embodiments do not describe all details exhaustively, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
