Abstract
Description
Technical Field
[0001] This application relates to the field of flow stabilizer technology, and more specifically, to a flow stabilizer material distribution device for a roller press. Background Technology
[0002] During the operation of the cement mill system, two streams of material enter the stabilizing chamber of the roller press. One stream is a fresh mixture of small lumps conveyed from the bottom of the batching silo, and the other stream is a coarse powder return from the disperser, which is mainly fine sand. The two streams of material enter the stabilizing chamber together at the top. Because the fresh material is fed into the upper part of the stabilizing chamber through a 50° inclined pipe chute and enters the chamber together with the vertically downward return from the disperser, the two streams of material do not mix fully before entering the chamber, resulting in segregation. This can easily lead to uneven force on the roller press, affecting the pressure and wear of the rollers. In addition, segregation may cause poor material flowability, affecting the uniformity of feeding, and thus affecting production efficiency and product quality. Utility Model Content
[0003] The purpose of this application is to provide a material distribution device for a roller press stabilizing chamber, which improves the uniformity of mixing two materials, enhances the extrusion effect of the roller press, and achieves the goal of increasing the hourly output of the cement mill and reducing power consumption.
[0004] This application provides a material distribution device for a roller press with a flow stabilizing chamber, which adopts the following technical solution:
[0005] A material distribution device for a roller press stabilizing chamber includes a mixing chamber disposed at the upper end of the stabilizing chamber. The mixing chamber has a funnel-shaped structure. Two feed pipes are disposed at the upper end of the mixing chamber. Multiple retaining rings are disposed inside the mixing chamber from top to bottom. The inner diameter of the retaining rings decreases sequentially from top to bottom. The retaining rings are attached to the inner wall of the mixing chamber.
[0006] Preferably, the mixing chamber has a ramp on the inner side of its upper end, and the ramp is located below the feed pipe.
[0007] Preferably, the slope has an inclination angle of 30°-45°.
[0008] Preferably, the outer wall at the lower end of the mixing chamber is provided with external threads.
[0009] Preferably, a sealing ring is provided on the outer wall of the lower end of the mixing chamber, and the sealing ring is located above the external thread.
[0010] Preferably, the retaining ring is made of metal.
[0011] Preferably, the outer surface of the retaining ring is coated with a wear-resistant layer.
[0012] Compared with the prior art, the beneficial effects of this application are as follows:
[0013] This application adds a mixing chamber to the upper end of the stabilizing chamber, and sets multiple baffle rings from top to bottom inside the mixing chamber. The material enters the mixing chamber through two feed pipes. After the material hits the baffle rings, it moves to the inside of the baffle rings and is mixed, which prolongs the residence time of the material inside the mixing chamber. By mixing in stages, the separation is eliminated, the uniformity of the two materials is improved, the extrusion effect of the roller press is improved, and the goal of increasing the hourly output of the cement mill and reducing power consumption is achieved.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] Example
[0025] like Figure 1 and Figure 2 As shown in the embodiment of this application, the roller press flow stabilizing chamber material distribution device includes a mixing chamber 2 disposed at the upper end of the flow stabilizing chamber 1. The mixing chamber 2 has a funnel-shaped structure. Two feed pipes 3 are disposed at the upper end of the mixing chamber 2. One feed pipe 3 is connected to a dispersing machine, and the other feed pipe 3 is connected to a batching silo. Multiple retaining rings 4 are disposed inside the mixing chamber 2 from top to bottom. The inner diameter of the retaining rings 4 decreases sequentially from top to bottom. The retaining rings 4 are attached to the inner wall of the mixing chamber 2.
[0026] During use, the material enters the mixing chamber 2 through two feed pipes 3. After impacting the baffle ring 4, the material moves to the inside of the baffle ring 4 and is mixed, which prolongs the residence time of the material inside the mixing chamber 2. By mixing in stages, the separation is eliminated, the uniformity of the two materials is improved, the extrusion effect of the roller press is improved, and the hourly output of the cement mill is increased while the power consumption is reduced.
[0027] In this embodiment, the upper inner side of the mixing chamber 2 has a ramp 5, which is located below the feed pipe 3. After the material enters the interior of the mixing chamber 2 through the feed pipe 3, it falls on the ramp 5 and then moves down the ramp 5, reducing the impact of the material on the retaining ring 4, delaying the wear of the retaining ring 4, and reducing the frequency of replacement of the retaining ring 4.
[0028] In this embodiment, the inclination angle of the ramp 5 is 30°-45°, specifically, the inclination angle is 40°.
[0029] In this embodiment, the outer wall at the lower end of the mixing chamber 2 is provided with external threads, and the mixing chamber 2 and the flow stabilizing chamber 1 are connected by threads. The use of threaded connection makes it easy to disassemble and assemble the mixing chamber 2.
[0030] In this embodiment, a sealing ring 6 is provided on the outer wall of the lower end of the mixing chamber 2. The sealing ring 6 is located above the external thread and is used to seal the mixing chamber 2 and the flow stabilizing chamber 1.
[0031] In this embodiment, the retaining ring 4 is made of metal in order to extend its service life.
[0032] In this embodiment, the outer surface of the retaining ring 4 is coated with a wear-resistant layer. The wear-resistant layer can further extend the service life of the retaining ring 4 and reduce the frequency of replacement.
[0033] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
