Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to a pulverizer for processing heat-insulating raw materials. Background Technology

[0002] Rock wool board is a new type of thermal insulation, fireproof, and sound-absorbing material, and its main raw material is basalt. Usually, basalt needs to be heated to a molten state, and then drawn into fibers to form inorganic wool. To facilitate high-temperature melting, basalt usually needs to be crushed into fine particles or powder. This crushing is not completed in one step, but usually requires multiple crushers to participate in different stages of crushing.

[0003] In the existing technology, roller crushers are a type of crusher commonly used in the production of rock wool boards. Among them, roller crushers often encounter the problem that basalt raw materials slip on the rollers and cannot be crushed, which leads to blockage and affects the crushing process. Utility Model Content

[0004] The purpose of this utility model is to provide a pulverizer for processing thermal insulation raw materials. This pulverizer can repeatedly squeeze the space between the round roller and the elliptical roller by rotating the elliptical roller, thereby pressing the basalt raw material onto the round roller and improving the stability of the pulverizing process.

[0005] This utility model provides a pulverizer for processing thermal insulation raw materials, comprising:

[0006] Two circular rollers are provided, and the two circular rollers are distributed at a distance from each other in the horizontal direction.

[0007] The elliptical rollers are provided in pairs, with the two elliptical rollers spaced horizontally apart and located directly above the circular roller.

[0008] The elliptical roller intermittently presses the raw material onto the circular roller by rotating, and the circular roller crushes the raw material by rotating.

[0009] Preferably, the minimum spacing between the elliptical rollers is at least equal to the spacing between the circular rollers.

[0010] Preferably, the two elliptical rollers rotate synchronously, and the two elliptical rollers rotate in opposite directions.

[0011] Preferably, there is a 90-degree rotation angle difference between the two elliptical rollers.

[0012] Preferably, the pulverizer for processing thermal insulation raw materials further includes a housing, the housing having a downward through channel, and the circular roller and the elliptical roller are both embedded in the inner wall of the housing.

[0013] Preferably, the pulverizer for processing thermal insulation raw materials further includes a conveyor belt, and the lower outlet of the outer shell is directly opposite the conveyor belt.

[0014] Preferably, the lower end outlet of the outer casing is located on the side wall of the outer casing, and the bottom plate of the outer casing is an inclined grid plate, with the end of the bottom plate of the outer casing near the lower end outlet of the outer casing inclined downward.

[0015] Preferably, the edges at both ends of the circular roller are integrally formed with stop protrusions, and the protrusion height of the stop protrusions is half the interval between the two circular rollers.

[0016] Preferably, the cylindrical surface of the circular roller is integrally formed with a groove, and the groove evenly covers the cylindrical surface of the circular roller.

[0017] Preferably, the cylindrical surface of the circular roller is integrally formed with protrusions, and the protrusions on the two circular rollers are staggered.

[0018] The technical solution of this utility model uses a rotating circular roller to crush basalt raw materials. An elliptical roller is located above the circular roller. During the rotation of the elliptical roller, the interval between the two elliptical rollers changes cyclically from large to small and from small to large. This process can crush large pieces of basalt raw materials. At the same time, during the process of the interval increasing, the elliptical roller will squeeze the space between the elliptical roller and the circular roller, thereby pressing the basalt raw materials tightly onto the surface of the circular roller. This allows the circular roller to crush the basalt raw materials more stably and ensures the stability of the basalt raw material crushing process. Attached Figure Description

[0030] Combination Figures 1 to 5As shown, the present invention provides a pulverizer for processing thermal insulation raw materials, which includes a circular roller 1 and an elliptical roller 2.

[0031] Combination Figures 1 to 5 As shown, there are two circular rollers 1, which are horizontally spaced apart; there are two elliptical rollers 2, which are horizontally spaced apart, and the elliptical rollers 2 are located directly above the circular rollers 1; the elliptical rollers 2 intermittently press the raw material onto the circular rollers 1 by rotating, and the circular rollers 1 crush the raw material by rotating.

[0032] In this embodiment, the basalt raw material is crushed by a rotating circular roller 1. An elliptical roller 2 is located above the circular roller 1. During the rotation of the elliptical roller 2, the interval between the two elliptical rollers 2 changes cyclically from large to small and from small to large. The larger interval allows larger pieces of basalt raw material to enter between the two elliptical rollers 2. Then, as the interval decreases, the elliptical roller 2 is used to crush the large pieces of basalt raw material. At the same time, as the interval increases, the elliptical roller 2 will squeeze the space between the elliptical roller 2 and the circular roller 1, thereby pressing the basalt raw material tightly onto the surface of the circular roller 1. This prevents the basalt raw material from sliding on the circular roller 1, which would affect the crushing process. This allows the circular roller 1 to crush the basalt raw material more stably, ensuring the stability of the basalt raw material crushing process.

[0033] The interval mentioned above refers to the minimum distance between the outer surfaces of two circular rollers 1 or elliptical rollers 2. Alternatively, the center distance can be used to define the circular rollers 1 and elliptical rollers 2. The center distance is the distance between the rotation axes of the two circular rollers 1 or elliptical rollers 2, and it is not affected by the shape of the elliptical roller 2 and will not change during its rotation. That is, the minimum interval between the elliptical rollers 2 is at least equal to the interval between the circular rollers 1, or the center distance between the elliptical rollers 2 is at least equal to the center distance between the circular rollers 1. In practice, the distance between the elliptical rollers 2 is generally slightly larger than the distance between the circular rollers 1.

[0034] In some embodiments, combined with Figure 1 , Figure 2 As shown, the two elliptical rollers 2 rotate synchronously in opposite directions. At this time, the difference in rotation angle between the two elliptical rollers 2 is zero, the range of variation of the interval between the two elliptical rollers 2 is the largest, and the upper limit of basalt raw material that can be accommodated is the largest.

[0035] In some embodiments, combined with Figure 2As shown, there is a 90-degree rotation angle difference between the two elliptical rollers 2. The range of variation of the interval between the two elliptical rollers 2 is reduced, but the action of pressing the basalt raw material to the circular roller 1 is more frequent. Compared with the case where the rotation angle difference is zero, this state is more suitable for cases where the basalt raw material is of higher quality, that is, the size is more uniform and there are no large pieces of raw material, and the crushing efficiency is higher.

[0036] In some embodiments, combined with Figure 1 , Figure 2 As shown, the pulverizer for processing thermal insulation raw materials also includes a shell 3. The shell 3 is provided with a downward through channel for basalt raw materials to pass through. The circular roller 1 and the elliptical roller 2 are both embedded in the inner wall of the shell 3 to ensure that the basalt raw materials fall into the position between the circular roller 1, thereby improving the stability of the pulverizing operation. This is because when the basalt raw materials fall into the position between the circular roller 1 and the shell 3, no pulverizing effect will occur.

[0037] In some embodiments, combined with Figure 3 As shown, the pulverizer for processing thermal insulation raw materials also includes a conveyor belt 4. The lower outlet of the outer shell 3 is directly opposite the conveyor belt 4. The conveyor belt 4 can transport the pulverized basalt raw material to the next processing stage. The lower outlet of the outer shell 3 can be opened on the side wall of the outer shell 3, and the bottom plate of the outer shell 3 can be an inclined grid plate to form a screen and increase the screening function. The bottom plate of the outer shell 3 is inclined downward at the end near the lower outlet of the outer shell 3 to ensure that the screened basalt raw material moves to the conveyor belt 4 through the lower outlet of the outer shell 3. At the same time, the number of conveyor belts 4 and the number of grid plate layers can be increased. Multiple conveyor belts 4 are responsible for transporting the basalt raw material screened by multiple grid plates.

[0038] In some embodiments, combined with Figure 4 , Figure 5 As shown, the edges of both ends of the circular roller 1 are integrally formed with baffle protrusions 11 to restrict the lateral diffusion of basalt raw material during the crushing process. The protrusion height of the baffle protrusions 11 is half the distance between the two circular rollers 1, so as to avoid the lateral diffusion of basalt raw material during the crushing process, which would squeeze the outer shell 3 and cause the outer shell 3 to deform.

[0039] In some embodiments, combined with Figure 4 , Figure 5As shown, the cylindrical surface of the circular roller 1 is integrally formed with grooves 12 or protrusions 13 to help concentrate force and improve crushing capacity. However, to ensure structural strength, the depth or height of the grooves 12 or protrusions 13 needs to be reduced. Therefore, the grooves 12 or protrusions 13 cannot help the circular roller 1 grip basalt raw materials. The grooves 12 or protrusions 13 should be evenly distributed across the cylindrical surface of the circular roller 1. However, when using the protrusions 13, the protrusions 13 on the two circular rollers 1 should be staggered to avoid collisions and reduce the risk of equipment damage.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
