Description

Technical Field

[0001] This utility model relates to the field of raw material processing, and in particular to a molecular sieve raw material crushing device. Background Technology

[0002] Molecular sieves are artificially synthesized hydrated aluminosilicates with molecule-screening properties. They possess advantages such as high adsorption capacity, strong selectivity, and high temperature resistance, and are widely used in organic and petrochemical industries. They are also excellent adsorbents for coal gas dehydration. Floral foam, made from phenolic plastic foam, is the main raw material for molecular sieve production. Currently, when this raw material is crushed by a crushing device, a negative pressure suction structure is introduced to transfer the crushed material. However, feedback indicates that the negative pressure adsorption space at the bottom of the crushing device has suction blind spots, resulting in residue of crushed material. Therefore, it is necessary to redesign a raw material crushing device specifically for molecular sieves to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a molecular sieve raw material pulverizing device to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0005] The molecular sieve raw material crushing device includes a box and a crushing structure set inside the box. The bottom of the box has a screen and a material gathering section. Between the screen and the material gathering section is a cavity for receiving the crushed material.

[0006] The material gathering section is recessed as a whole, and the center of the recess is a tubular structure with channels. There are several slots on the side of the tubular structure facing the screen, and the slots allow the crushed material to enter the tubular structure.

[0007] It also includes a first pipe that connects to the pump set and is connected to the tubular structure, which transfers the crushed material that falls to the aggregate section under the suction of the pump set.

[0008] Preferably, the tubular structure in the aggregate section is connected to the screen.

[0009] Preferably, the box body has a hopper, which guides the raw materials into the box body and into contact with the crushing structure.

[0010] Preferably, it also includes a drive unit that drives the crushing structure to rotate axially within the chamber.

[0011] Preferably, the crushing structure includes a main shaft disposed inside the housing and a crushing section fixedly connected to the main shaft inside the housing; the main shaft extends outward from the housing, and the outwardly extended portion is connected to the drive section for transmission.

[0012] Preferably, the portion of the main shaft extending outward from the housing is equipped with a driven wheel, and the drive unit includes a motor and a drive wheel on which the motor drive unit is mounted, with the drive wheel and the driven wheel connected by a transmission belt.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model addresses the characteristics of molecular sieve raw materials by gathering the pulverized material into the negative pressure range under the original negative pressure process, thus avoiding the suction residue problem caused by the negative pressure blind zone between the suction port and the corner of the plate in the traditional flat material gathering structure.

[0015] 2. The material gathering section proposed in this utility model provides strong support for the screen while gathering the crushed material, thereby improving the overall structural strength of the equipment. Attached Figure Description

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] Example 1

[0026] This embodiment presents a molecular sieve raw material pulverizing device; please refer to [link / reference]. Figures 1-5 The molecular sieve raw material pulverizing device includes a housing and a pulverizing structure disposed within the housing, such as... Figures 1-3 As shown, the box is composed of a frame 2 and a flip cover 3. In addition, a base 1 for support is provided at the bottom of the frame 2.

[0027] Please see Figure 1 and Figure 2 The flip cover 3 is combined with the frame 2 by a hinge or other rotatable connection structure. The frame 2 is a frame-shaped structure with upper and lower frame openings. The upper frame opening is covered by the flip cover 3, and the lower frame opening is equipped with... Figure 4 The screen 14 shown.

[0028] Please see Figure 2 and Figure 4 Above the screen 14 is a crushing structure, which includes a main shaft set in the frame 2 and a crushing part 12 fixedly connected to the main shaft in the frame 2.

[0029] To further clarify, the spindle is not shown in the attached drawing, but it has a matching structure; please refer to [link / reference needed]. Figures 1-3 A bracket 6 is located on the side of frame 2, and a bearing 7 is installed above the bracket 6. The bearing 7 is the fixing part of the main spindle, and at the same time, the bearing 7 is also the support part for the main spindle extending outward from frame 2. Figure 1 and Figure 2 As shown, the main shaft is supported by the bearing 7 and extends outward, with the driven wheel 8 installed on the outward-extending part.

[0030] To further explain, the main shaft is equipped with a drive unit, which includes a motor 9 fixed above the base 1 and a drive wheel 10 on which the drive part of the motor 9 is mounted. The drive wheel 10 and the driven wheel 8 are connected by a transmission belt 11, so that the crushing part 12 connected to the main shaft can rotate in the frame 2.

[0031] Please see Figure 2 In this embodiment, the crushing section 12 is composed of multiple disc-shaped structures, with blades 13 between adjacent disc-shaped structures. Thus, it can crush materials... Figure 1 The raw materials entering the box body are shown in hopper 4.

[0032] Please see Figure 4 and Figure 5 Below the screen 14 is a material gathering section 15 located at the bottom opening of the frame 2. Between the material gathering section 15 and the screen 14 is a receiving chamber for storing the crushed material. Unlike most materials, floral foam made from phenolic plastic foam, due to its lightweight nature, can be transferred to the next process via a negative pressure procedure after crushing. The material gathering section 15 proposed in this embodiment facilitates the transfer of the crushed material.

[0033] Please continue reading. Figure 4 and Figure 5 The material gathering section 15 consists of a second pipe 153 and arc-shaped plates 151 disposed on both sides of the second pipe 153. It should be noted that the arc-shaped plates 151 are upward relative to the second pipe 153, and the arc surface of the arc-shaped plates 151 can guide the crushed material to slide down into the setting range of the second pipe 153.

[0034] To further explain, the second pipe 153 has several slots 154 on the side facing the screen 14. These slots 154 guide the crushed material into the second pipe 153, thus preventing it from entering the negative pressure blind zone. Furthermore, the structure between adjacent slots 154 remains the same, and the overall strength of the material-gathering section 15 does not change. In addition, the second pipe 153 is connected to the screen 14, providing support and preventing complex deformation of the screen 14 during long-term operation. Moreover, a reinforcing plate 152 is provided at the bottom of the combination of the second pipe 153 and the arc-shaped plate 151, further providing strength support.

[0035] Please see Figure 3 and Figure 4 This embodiment proposes that the molecular sieve raw material crushing device also includes a first pipe 5 connected to the pump group and connected to the second pipe 153. The first pipe 5 can transfer the crushed material that falls to the aggregate section 15 under the suction of the pump group.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
