Description

Technical Field

[0001] This utility model relates to the field of roller press technology, and in particular to a pressure reducing device for a roller press flow stabilizing chamber. Background Technology

[0002] Roller presses, as the most efficient crushing equipment to date, have experienced rapid development over the past 20 years and are widely used in the crushing of cement, industrial waste, and various ores. Roller presses utilize a single-particle crushing-as-a-group operation to achieve layered material crushing. Specifically, in operation, the material in the flow stabilizing chamber, used in conjunction with the roller press, is rapidly crushed under high pressure by two opposing rotating rollers. This results in small particle sizes and numerous newly generated microcracks within the particles, significantly improving grindability and grinding efficiency. The main function of the flow stabilizing chamber is to provide a continuous and stable column of material for the roller press. The internal structure of the chamber directly affects the flow stabilization effect. An improper design can easily lead to uneven material distribution within the chamber, or even problems such as material shoving and segregation. Such situations occur frequently in production, but have not yet received sufficient attention.

[0003] A flow stabilizing bin for a roller press typically consists of a cylinder, support components, a weighing unit, and a material distribution device, and its structure is relatively simple. The function of the flow stabilizing bin is to create conditions for maintaining stable and continuous material pressure in the roller press by stabilizing the material flow. Changes in bin weight also provide a basis for the central control room to adjust the material inflow and outflow balance of various systems. In addition, in the event of an emergency system shutdown, the flow stabilizing bin can also buffer material in the conveying equipment and chutes. It is evident that the structural design of the key components of the flow stabilizing bin is crucial to the stable operation of the system. Existing roller press flow stabilizing bins are prone to uneven material distribution due to material segregation, which can lead to material overflow or even roller press tripping.

[0004] Therefore, how to overcome the defects of the existing technology and how to solve the problem that the existing roller press flow stabilizing bin is prone to uneven material distribution, causing the roller press to slam or even trip due to the effect of material segregation, are urgent problems to be solved in this technical field. Utility Model Content

[0005] Addressing the shortcomings or improvement needs of existing technologies: How to solve the problem of uneven material distribution in the current roller press stabilizing chamber, which is prone to material overflow or even machine tripping due to material segregation? This utility model proposes a pressure-reducing device for the roller press stabilizing chamber. By installing a material distribution baffle inside the stabilizing chamber, with the baffle facing the feed inlet, the material forms a natural accumulation angle on the baffle. Overflowing material is then evenly distributed around the stabilizing chamber, thus achieving uniform material distribution. This material distribution baffle has a simple structure, and its position can be determined according to the actual site conditions. When the chamber is empty, the baffle also prevents large pieces of material from directly impacting the roller surface, providing protection.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0033] like Figure 1As shown in the figure, this utility model embodiment provides a pressure reducing device for a roller press's flow stabilizing chamber, including a material distribution baffle 2 disposed within the flow stabilizing chamber 1. The material distribution baffle 2 is horizontally disposed within the flow stabilizing chamber 1, with its center aligned with the feed inlet 101 of the flow stabilizing chamber 1. There is a gap between the perimeter of the material distribution baffle 2 and the inner wall of the flow stabilizing chamber 1. Furthermore, the area of ​​the material distribution baffle 2 is larger than the area of ​​the feed inlet 101. With this arrangement, when material is poured into the flow stabilizing chamber 101, the material falls onto the material distribution baffle 2, forming a natural accumulation angle. Overflowing material is then evenly distributed from the gap between the perimeter of the material distribution baffle 2 and the inner wall of the flow stabilizing chamber 1, thus achieving uniform material distribution. This material distribution baffle 2 has a simple structure, and its position can be determined according to the actual site conditions. When the chamber is empty, the material distribution baffle 2 can also prevent large pieces of material from directly impacting the roller surface below, providing protection.

[0034] refer to Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the fabric baffle 2 is fixed inside the flow stabilizing chamber 1 by a support assembly 3. The support assembly 3 includes a plurality of first support beams 301 and a plurality of second support beams 302. The fabric baffle 2 is fixed to the first support beams 301 by the second support beams 302, and the first support beams 301 are fixed inside the flow stabilizing chamber 1. By fixing the fabric baffle 2 inside the flow stabilizing chamber 1 by the first support beams 301 and the second support beams 302, a gap can be maintained between the fabric baffle 2 and the inner wall of the flow stabilizing chamber 1.

[0035] In some embodiments, the first support beam 301 includes a first I-beam, and a plurality of the first I-beams are arranged in parallel; the length of the first I-beam is greater than the length of the fabric baffle 2 in the first direction, and the two ends of the first I-beam are fixed to the inner wall of the flow stabilizing chamber 1. Specifically, two first I-beams can be provided, and the two first I-beams are respectively located on both sides below the fabric baffle 2 along the first direction of the fabric baffle 2, so as to cooperate with the second I-beam to achieve stable installation of the fabric baffle 2.

[0036] In some embodiments, the second support beam 302 includes a second I-beam, and a plurality of second I-beams are arranged in parallel. The length of the second I-beam is equal to the length of the fabric baffle 2 in the second direction. The top surface of the second I-beam is fixed to the bottom surface of the fabric baffle 2, and the bottom surface of the second I-beam is fixed to the top surface of the first I-beam. The second I-beam is arranged perpendicular to the first I-beam. Specifically, three second I-beams can be provided, and the three second I-beams are respectively located on both sides and the middle of the bottom of the fabric baffle 2 along the second direction of the fabric baffle 2, so as to cooperate with the first I-beam to achieve stable installation of the fabric baffle 2.

[0037] refer to Figure 4 As shown, in some embodiments, the length of the fabric baffle 2 in the first direction is greater than its length in the second direction. In some embodiments, the fabric baffle 2 has outwardly projecting arc shapes on both sides in the first direction, and parallel straight shapes on both sides in the second direction. (See reference...) Figure 5 As shown, in some embodiments, the first direction of the fabric baffle 2 is parallel to the axial direction of the rollers 4 of the roller press. In some embodiments, the length of the fabric baffle 2 in the second direction is less than the distance between the axes of the two rollers 4. It should be noted that the first direction of the fabric baffle 2 in this embodiment is also as shown in the figure. Figure 4 The direction indicated by arrow A in this embodiment is the second direction of the fabric baffle 2, which is also as shown in the image. Figure 4 The direction indicated by arrow B is perpendicular to the direction indicated by arrow A. When the two rollers 4 are working, they rotate in opposite directions to compress the material. This arrangement allows the material to be discharged between the axes of the two rollers 4 as much as possible, reducing the possibility of material being discharged from the outer sides of the rollers 4 and preventing material segregation due to roller 4 deviation.

[0038] In addition, during the material feeding process from the discharge port 103 of the flow stabilizing chamber 1 to the surface of the roller 4, there was an upper material impact, which was equivalent to a hammer vibrating the entire material column, thus speeding up the feeding process. However, in this embodiment, after adding the material baffle 2, this impact is isolated, so that the lower material column only falls under its own gravity, which reduces the feeding speed and improves the squeezing effect of the roller 4.

[0039] refer to Figure 6 and Figure 7 As shown, in some embodiments, the feed inlet 101 is located at the top of the flow stabilizing chamber 1, and an exhaust port 102 is provided on one side of the feed inlet 101. An outlet 103 is provided at the bottom of the flow stabilizing chamber 1. The exhaust port 102 allows for the proper discharge of gas from the material, thus mitigating the problem of unstable material flow.

[0040] In some embodiments, a grid frame 104 is provided on the outer periphery of the flow stabilizer 1. The grid frame 104 strengthens the structural strength of the flow stabilizer 1 and allows the impact load of the flow stabilizer 1 to be dispersed and released.

[0041] In summary, this utility model proposes a pressure-reducing device for a flow stabilizing chamber in a roller press. By installing a material distribution baffle inside the flow stabilizing chamber, with the baffle directly facing the feed inlet, the material forms a natural accumulation angle on the baffle. Overflowing material is then evenly distributed around the flow stabilizing chamber, thus achieving uniform material distribution. This material distribution baffle has a simple structure, and its position can be determined according to actual site conditions. When the chamber is empty, the baffle also prevents large pieces of material from directly impacting the roller surface, providing protection.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this specification are prior art known to those skilled in the art.
