An energy-saving feeding device for a stabilized cement raw material roller press

Abstract

This invention discloses an energy-saving feeding device for a stabilized cement raw material roller press, comprising a feeding structure, a channel structure at the top of the feeding structure, a flow stabilizing component at the top of the channel structure, a gate valve assembly at the top of the flow stabilizing component, and a hopper assembly at the top of the gate valve assembly. In this invention, the rotating sleeve in the feeding structure can drive the side baffle assembly to rotate, thus adjusting the gap between the ends of the two side baffle assemblies. After the angle of the side baffle assembly is adjusted, the height of the side baffle is adjusted for compensation, ensuring that the gap between the end of the side baffle and the extrusion roller is compliant and avoiding edge effects. The gate valve assembly uses a frame-type valve plate to adjust the opening. When the opening is changed, a second cylinder drives the frame-type valve plate to the sealed channel, allowing some particles to enter the sealed channel. When the frame-type valve plate returns to its original position, the internal material is pushed into the feeding channel, thus preventing material particles from clogging the sealed channel.

Description

Technical Field

[0001] This invention relates to the field of cement roller press equipment technology, specifically to an energy-saving stable cement raw material roller press feeding device. Background Technology

[0002] Cement roller presses are very important grinding equipment in modern cement production lines. They usually do not complete the final grinding alone, but are combined with ball mills to form a combined grinding system. They are mainly used for pre-grinding of materials, aiming to significantly increase the output of the entire grinding system and reduce energy consumption. Their core working principle is to apply extremely high pressure to the material through two opposing rotating extrusion rollers, compressing the material into a dense cake. During this process, numerous cracks are generated inside the material particles, and they may even be directly crushed, thus greatly improving the grindability of the material. When these material cakes are then fed into the ball mill, the energy consumption during ball milling is significantly reduced, achieving an energy-saving effect. Roller presses require feeding equipment to continuously and evenly feed the raw material between the two extrusion rollers. For example, Chinese invention patent CN111215182B discloses a cement roller press with smooth feeding and a crushing roller cleaning function, including a main body, a feed hopper, a mounting frame, two crushing rollers, and two power units. It also includes an extrusion mechanism and two cleaning mechanisms. The cleaning mechanism includes a support sleeve, a lifting rod, a cleaning brush, a support wheel, a spring, a first striking block, and a second striking block. The extrusion mechanism includes a bracket, lead screw, fixed bearing, ball screw bearing, pressing plate, first connecting rod, two drive components, two support components, and at least two crushing teeth. The above-mentioned feeding structure is relatively simple, while the current roller press feeding structure is more complex. It must ensure a continuous, stable, and full material flow and form effective material column pressure. It consists of a hopper, slide gate valve, hopper, and side baffles. The slide gate valve's function is to adjust the raw material flow rate by adjusting its opening, thus controlling the thickness and speed of the formed material column. The hopper is a connecting channel that introduces the material column into the roller press. The side baffles are installed at both ends of the extrusion roller, maintaining a very small gap with the roller surface to prevent material leakage. However, the current roller press feeding structure has the following drawbacks:

[0003] Because the material pressure inside the hopper varies, including due to the intervention of the slide gate valve, the pressure and particle size of the material entering from the side baffle at the end of the hopper will change, leading to material dispersion. Therefore, the side baffles in the current roller press feeding structure are designed with adjustable angles to ensure that the distance between the ends of the two side baffles matches the particle size and pressure of the material column, preventing the dispersion of the material column. However, adjusting the angle will change the gap between the side baffle and the extrusion roller. When the gap is large, an edge effect will occur, meaning that the material in the edge area is not fully extruded, causing the material to escape from the crushing area, resulting in leakage and affecting the particle size distribution of the final product, which is not conducive to use. Secondly, when adjusting the opening of the slide gate valve currently used, because the raw material itself has a small particle size, some raw material particles may enter the valve plate groove, causing blockage in the valve plate movement position. Therefore, a blowing cleaning structure is set up to assist in cleaning, which increases the energy consumption of the slide gate valve and is not energy-efficient.

[0004] Therefore, we propose an energy-saving stable cement raw material roller press feeding device to solve the above problems. Summary of the Invention

After the angle of the side baffle assembly is adjusted, the height of the side baffle is adjusted for compensation, ensuring that the gap between the end of the side baffle and the extrusion roller is compliant, avoiding edge effects, and ensuring that the particle size distribution of the final material cake is uniform. In the slide valve assembly of this invention, a frame-type valve plate is used to adjust the opening. When the opening is changed, the second cylinder drives the frame-type valve plate to the sealing channel. This allows some particles to enter the sealing channel, but they will be located inside the frame-type valve plate. When the frame-type valve plate returns to its original position, the inside will push the material into the feeding channel. This prevents material particles from clogging the sealing channel, eliminating the need for additional cleaning equipment and making it more energy-efficient. Attached Figure Description

When the opening degree is changed, the second cylinder 412 drives the frame valve plate 48 to the sealing channel 415. In this way, some particles will enter the sealing channel 415, but will be inside the frame valve plate 48. When the frame valve plate 48 returns to its original position, the inside will push the material into the feed channel 46. This will prevent the material particles from blocking the sealing channel 415, eliminating the need for additional cleaning equipment and making it more energy-efficient.

[0045] The second cylinder 412 is fixedly connected to the end of the second plate-shaped hopper 43. The output end of the second cylinder 412 is located inside the first inner cavity 49 and is fixedly connected to the power plate 410. The power plate 410 is fixedly connected to the end of the plate-shaped valve plate 411 and is slidably sleeved inside the first inner cavity 49. The lower channel 45 is fixedly connected to the bottom surface of the valve body 41, and the upper channel 44 is fixedly connected to the top surface of the valve body 41. Both the upper channel 44 and the lower channel 45 are connected to the feed channel 46. The bottom end of the lower channel 45 is fixedly sleeved with the third upper mounting frame 417. The top of the third upper mounting frame 417 is... A third sealing frame 418 is fixedly connected to the edge of the surface. Multiple third upper threaded through holes 419 are vertically opened on the third upper mounting frame 417. The third sealing frame 418 is inserted into the third sealing frame groove 319. The third lower threaded through hole 320 and the third upper threaded through hole 419 are threadedly connected to the third bolt 8. The top of the upper channel 44 is fixedly sleeved with the fourth lower mounting frame 420. A fourth sealing frame groove 421 is opened at the edge of the top surface of the fourth lower mounting frame 420. Multiple fourth lower threaded through holes 422 are vertically opened on the fourth lower mounting frame 420.

[0046] The silo assembly 5 includes a pressure-stabilizing silo 51. The bottom surface of the pressure-stabilizing silo 51 is fixedly connected to and connected to a material pipe 52. The bottom end of the material pipe 52 is fixedly sleeved with a fourth upper mounting frame 53. A fourth sealing insert frame 54 is fixedly connected to the bottom edge of the fourth upper mounting frame 53. Multiple fourth upper threaded through holes 55 are vertically opened on the fourth upper mounting frame 53. The fourth sealing insert frame 54 is inserted into a fourth sealing frame groove 421. The fourth lower threaded through hole 422 and the fourth upper threaded through hole 55 are threadedly connected with fourth bolts 9. The pressure-stabilizing silo 51 is used to receive materials conveyed by upstream feeding equipment, such as belt scales and screw conveyors.

[0047] In use, the main frame 11 is installed on top of the roller press, and the guide plate 13 is inserted into the roller press inlet. During operation, the upstream feeding equipment feeds the material into the pressure-stabilizing silo 51. The slide valve assembly 4 adjusts its opening according to the material discharge requirements. After passing through the slide valve assembly 4, the material enters the flow stabilizing assembly 3, which controls the material flow rate. The resulting column of material passes through the channel structure 2 and enters between the extrusion rollers of the roller press. The two side baffle assemblies 14 ensure that the column does not disperse and prevents edge effects that could cause leakage. The column then undergoes roller pressing between the extrusion rollers. In this invention, the rotating sleeve 19 in the discharge structure 1 can drive the side baffle assembly 14 to rotate, thus adjusting the gap between the ends of the two side baffle assemblies 14. This allows the gap to match the thickness and pressure of the column, preventing material dispersion. To ensure the material column enters normally between the two extrusion rollers, after the angle of the side baffle assembly 14 is adjusted, the height of the side baffle 142 is adjusted for compensation to ensure that the gap between the end of the side baffle 142 and the extrusion roller is compliant, avoid edge effects, and ensure that the particle size distribution of the final formed cake is uniform. In the slide valve assembly 4 of this invention, a frame-type valve plate 48 is used to adjust the opening. When the opening is changed, the second cylinder 412 drives the frame-type valve plate 48 to push it to the sealing channel 415. In this way, some particles will enter the sealing channel 415, but will be inside the frame-type valve plate 48. When the frame-type valve plate 48 returns to its original position, the inside will push the material into the feed channel 46. This will prevent the material particles from blocking the sealing channel 415, eliminating the need for additional cleaning equipment and saving energy.
