Description

Technical Field

[0001] The utility model relates to the technical field of stone granule sorting, in particular to a dust removal structure used for stone granule sorting and dust removal. Background Art

[0002] When the stone is crushed into stone particles, there is a lot of stone powder / dust, which needs to be sorted by dust removal equipment. In the sorting process, a conveying mechanism is usually built to feed the material from the top of the dust removal equipment; a conical hopper is set at the top of the dust removal equipment to convey the material into the conical hopper.

[0003] Stone sorting and dust removal refers to blowing away the dust in the stone and retaining the useful stone particles. In order to blow away the dust more fully, it is necessary to first evenly disperse the mixture of stone particles and dust, and then use a fan to blow away the dust.

[0004] In the prior art, the commonly used dust removal method is to let the material fall, set a fan on one side of the material, and set a dust outlet on the other side. When the fan rotates, the powder will be blown away. However, the problem with this method of the prior art is that it can only perform dust removal and sorting on the stone once, and the dust removal effect is not particularly ideal. The easy-to-think-of method is to improve the dust removal effect by performing dust removal multiple times, but this method is too inefficient.

[0005] To this end, our company has improved the dust removal structure to achieve the requirements of both dust removal efficiency and dust removal effect.

[0006] It should be noted that this solution designs a new sorting and dust removal equipment. In order to fully protect the entire equipment, it is divided into multiple patent solutions. This solution only protects the dust removal structure. Utility Model Content

[0007] The utility model aims to overcome the shortcomings of the prior art and provide a dust removal structure for stone particle sorting and dust removal which has both dust removal effect and dust removal efficiency and good stability.

[0008] It should be noted that our company's initial design idea was to set up a vertical cylinder, set up multiple fans at different heights of the vertical cylinder, and multiple dust outlets for the same purpose. When the material leaks from the vertical cylinder, it will flow into different fan positions in sequence, thereby achieving a higher dust removal effect and dust removal efficiency. However, this method will cause the height of the vertical cylinder to be particularly high, resulting in an unstable center of gravity. For this reason, further improvements were made on the original design idea, and stability must be guaranteed on the basis of ensuring efficiency and dust removal effect.

[0009] The purpose of the utility model is achieved through the following technical solutions: a dust removal structure for sorting and dust removal of stone particles, a mechanism for circumferentially dispersing the material is arranged above the dust removal structure, including a vertically arranged dust removal cylinder and a plurality of inverted conical shells;

[0010] In the dust removal cylinder, a plurality of inverted cone-shaped shells are arranged at intervals in the height direction, and adjacent inverted cone-shaped shells are supported by support rods to form an interval dust removal space;

[0011] An air outlet is arranged on the side of the dust removal cylinder, and the air outlet is connected to the fan; a negative pressure tube is arranged at the upper part of the dust removal cylinder;

[0012] The material falls from above onto the side wall of the top inverted cone shell and flows downward along the side wall. The corresponding material falls onto the side wall of the next inverted cone shell through the spacing dust removal space. The wind generated by the fan passes through the spacing dust removal space and is discharged from the negative pressure pipe. The wind blows the dust upward to form dust removal.

[0013] As a preferred technical solution of the present application, an elliptical piece is provided at the center of the lower end of the inverted conical shell, and the elliptical pieces of all the inverted conical shells are fixed by the column B. When the material of the upper inverted conical shell flows downward, the material will contact the corresponding elliptical piece when flowing to the center of the lower end of the corresponding inverted conical shell, so that the material is dispersed.

[0014] As a preferred technical solution of the present application, in the dust collecting cylinder, the edge of the uppermost inverted cone shell contacts the inner wall of the dust collecting cylinder, and a receiving bin is provided below the lowermost inverted cone shell; the receiving bin cuts off the dust collecting cylinder, and a bin door that can be opened and closed automatically is provided on the receiving bin; a pressure chamber is formed between the receiving bin, the uppermost inverted cone shell and the corresponding dust collecting cylinder. When the fan generates wind, a certain pressure will be generated in the pressure chamber, allowing the pressurized wind to flow upward through the dust collecting space and raise dust upward.

[0015] As a preferred technical solution of the present application, the receiving bin is a conical bin, a bin door is provided at the bottom of the receiving bin, one side of the bin door is provided on a mounting seat via a rotating shaft, and a torsion spring is provided on the corresponding rotating shaft. When the material in the receiving bin is not enough to overcome the pressure of the torsion spring, the bin door is in a closed state, allowing the pressure in the pressure chamber to be suppressed; when a certain weight of material is accumulated in the receiving bin to overcome the force of the torsion spring, the bin door automatically opens and the material is automatically discharged.

[0016] As a preferred technical solution of the present application, a material distribution cylinder and a material feeding cylinder are sequentially arranged above the dust removal cylinder, and an impeller is arranged in the material distribution cylinder. When the material falls downward into the material distribution cylinder through the material feeding cylinder, the material contacts the impeller, thereby dispersing the material circumferentially.

[0017] For ease of understanding, the core design points and principles of this solution are explained below: a. The material flows through the upper and lower layers of the inverted conical shells, and will flow through the spacing dust removal space between adjacent inverted conical shells. The wind generated by the fan will also flow upward from the spacing dust removal space, so that the powder in the material can be blown away upward; b. Since the powder in the material has a certain weight, the corresponding dust removal cylinder is cut off by the topmost inverted conical shell and the receiving bin to form a pressure chamber, so that the heavy powder can also be blown away from above; c. Since multiple inverted conical shells are connected by struts, there is a spacing dust removal space between adjacent inverted conical shells. In this way, a large fan can be used to directly remove dust from the corresponding multiple spacing dust removal spaces, which can not only ensure the dust removal efficiency, but also ensure the dust removal effect and stability.

[0018] The utility model has the following advantages:

[0019] It has the functions of high dust removal efficiency, good dust removal efficiency and good stability;

[0020] Specifically, when the material flows from top to bottom, it flows into the corresponding dust removal spaces with different spacings, and dust removal can be performed in each dust removal space. Multiple dust removals can be achieved with one flow, so the dust removal efficiency is high and the dust removal effect is good.

[0021] In addition, the material is well dispersed above the dust removal structure, and the material is subsequently prevented from agglomerating under the action of the cone. The material can be well dispersed when flowing through the entire pressure chamber, which is conducive to the wind sweeping away the powder in the material, further improving the dust removal effect.

[0022] In addition, pressurized air is formed in the pressure chamber, and negative pressure is formed in the negative pressure tube, so the pressurized air can well sweep away the powder in the material, further improving the dust removal efficiency;

[0023] In this solution, since only one fan is provided, one fan corresponds to multiple dust removal spaces, so that the center of gravity is lowered and the stability of the entire device is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0032] (Example 1)

[0033] See also Figure 1-Figure 3 A dust removal structure for sorting and dust removal of stone particles, a mechanism for circumferentially dispersing the material is arranged above the dust removal structure, and the dust removal structure includes a vertically arranged dust removal cylinder 300 and a plurality of inverted cone-shaped platform shells 310;

[0034] In the dust removal cylinder 300, a plurality of inverted cone-shaped shells 310 are arranged at intervals in the height direction, and adjacent inverted cone-shaped shells 310 are supported by support rods 311 to form a dust removal space, and the bottom inverted cone-shaped shells 310 are welded and fixed to the inner wall of the dust removal cylinder 300 by a plurality of short cross bars A;

[0035] An air outlet is provided on the side of the dust removal cylinder 300, and the air outlet is connected to the fan; a negative pressure tube 320 is provided at the upper part of the dust removal cylinder 300;

[0036] In addition, an elliptical member 330 is provided at the center of the lower end of the inverted conical housing 310, and all the elliptical members 330 of the inverted conical housing 310 are installed and fixed via a column B331, and the lower end of the column B331 is welded and fixed to the inner wall of the dust removal cylinder 300 via a plurality of long cross bars B;

[0037] During operation: 1. Materials fall from above onto the inner wall of the uppermost inverted cone shell 310, and the materials flow downward along the corresponding inner wall. When the materials reach the lower end of the uppermost inverted cone shell 310, part of the materials fall directly downward, and part of the materials gather at the center of the lower end of the uppermost inverted cone shell 310. The gathered materials contact the surface of the elliptical member 330, so the gathered materials are dispersed again to ensure that the entire materials are in a good dispersed state. In this way, the materials gradually fall from top to bottom onto the inverted cone shells 310 of different layers, and the materials fall through the corresponding spacing dust removal spaces. 2. The wind generated by the fan enters the dust removal cylinder 300 through the air port. At the same time, since the upper part of the dust removal cylinder 300 has a negative pressure tube 320, the wind will flow upward along the inverted cone shell 310 through the corresponding spacing dust removal space, and the powder in the dispersed materials can be rolled up well at the spacing dust removal space and discharged from the negative pressure tube 320.

[0038] It should be noted that when the material flows from top to bottom, it flows into the corresponding dust removal spaces with different spacings respectively. Dust removal can be carried out in the dust removal spaces at each spacing. Multiple dust removals can be achieved with one flow, so the dust removal efficiency is high and the dust removal effect is good. This is achieved by well dispersing the material above the dust removal structure and subsequently avoiding material aggregation under the action of the elliptical member 330. The material can be well dispersed when flowing through the entire pressure chamber, which is conducive to the wind to blow away the powder in the material, thereby further improving the dust removal effect. Since only one fan is provided, one fan corresponds to multiple dust removal spaces at different spacings, so that the center of gravity is lowered, thereby ensuring the stability of the entire device.

[0039] In this embodiment, refer to Figure 1 and Figure 2 In the dust collecting cylinder 300, the edge of the uppermost inverted cone shell 310 contacts the inner wall of the dust collecting cylinder 300, and a receiving bin 340 is provided below the lowermost inverted cone shell 310, and the receiving bin 340 cuts off the dust collecting cylinder 300, and a bin door 341 which can be opened and closed automatically is provided on the receiving bin 340; thus, a pressure chamber 301 is enclosed between the receiving bin 340, the uppermost inverted cone shell 310 and the corresponding dust collecting cylinder 300;

[0040] When the fan generates wind, a certain pressure is generated in the pressure chamber 301, and pressurized air is formed in the pressure chamber 301, while negative pressure is formed in the negative pressure tube 320. Therefore, the pressurized air can effectively roll away the powder in the material, further improving the dust removal efficiency, and rolling up the heavier powder to achieve a better dust removal effect.

[0041] In this embodiment, refer to Figure 2The receiving bin 340 is a conical bin, and a bin door 341 is provided at the bottom of the receiving bin 340. One side of the bin door 341 is provided on a mounting seat 342 via a rotating shaft, and a torsion spring is provided on the corresponding rotating shaft. When the material in the receiving bin 340 is not enough to overcome the pressure of the torsion spring, the bin door 341 is in a closed state, allowing the pressure chamber 301 to be suppressed; when a certain weight of material is accumulated in the receiving bin 340 to overcome the force of the torsion spring, the bin door 341 automatically opens and the material is automatically discharged.

[0042] It should be noted that, see Figure 1 A material distribution cylinder and a material feeding cylinder are sequentially arranged above the dust removal cylinder 300, and an impeller 70 is arranged on the material distribution cylinder. When the material falls downward into the material distribution cylinder through the material feeding cylinder, the material contacts the impeller 70, so that the material is dispersed circumferentially.

[0043] In this embodiment, refer to Figure 3 The heights of the multiple inverted cone shells 310 in the dust removal cylinder 300 are consistent, and the diameters of the multiple inverted cone shells 310 gradually decrease from top to bottom; and between adjacent inverted cone shells 310, the lower end diameter of the inverted cone shell 310 in the upper layer is smaller than the upper end diameter of the inverted cone shell 310 in the lower layer, so as to prevent a large amount of material from splashing out of the inverted cone shell 310. In addition, it should be noted that some materials will splash out of the inverted cone shell 310, but dust removal can still be performed normally.

[0044] In this embodiment, refer to Figure 3 The column B331 passes through the multiple elliptical pieces 330 up and down and is then locked with corresponding nuts.

[0045] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
