Description

Technical Field

[0001] The utility model relates to the technical field of stone particle sorting, in particular to a wind guiding structure used for stone particle 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; and this air flow method is not intense enough, and the dust removal effect is not particularly ideal.

[0005] To this end, our company has made improvements to the dust removal structure, mainly improving the wind guiding structure so that it can generate violent wind for dust removal.

[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 wind guiding structure. Utility Model Content

[0007] The utility model aims to overcome the shortcomings of the prior art and provide a wind guiding structure for stone material sorting and dust removal, which can have a pressure difference in the upper and lower directions, thereby facilitating the upward flow of compressed air, can better carry away powder, and has a good dust removal effect.

[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 wind guide structure for stone material sorting and dust removal, including a dust removal cylinder, a large fan, and a wind cylinder seat;

[0010] The dust removal cylinder is arranged vertically, and the material flows from top to bottom;

[0011] An air distribution cylinder seat is arranged in the middle of one side of the dust removal cylinder, and the air distribution cylinder seat is connected to the large fan; a negative pressure tube is arranged at the upper part of the other side of the dust removal cylinder;

[0012] The air distribution cylinder seat has a horizontal cylinder channel, and a plurality of partitions are arranged in the cylinder channel, and the partitions divide the cylinder channel into multiple layers of small channels, and the channel space of the multiple small channels gradually decreases from bottom to top;

[0013] When a large fan generates compressed air, the compressed air is divided and enters different small channels, and the air volume in multiple small channels from bottom to top gradually decreases; when the compressed air flows from the middle of one side of the dust collector to the upper part of the other side, the air in the small channels on the lower layer can assist the air in the small channels on the upper layer to flow; when the air flows from bottom to top, it will carry the powder in the material.

[0014] As a preferred technical solution of the present application, the number of the dividing piece is one, and the cylinder channel is divided into two small channels; the cross-section of the dividing piece is semi-elliptical, so that the two small channels have a large space at the air inlet and a small space at the air outlet, allowing the air to be further compressed in the corresponding small channel.

[0015] As a preferred technical solution of the present application, the dust collecting cylinder is provided with two inverted conical shells, one regular conical shell, and a material receiving bin at intervals from top to bottom; the upper inverted conical shell is connected to the lower inverted conical shell via support rods, and a dust collecting spacing space is formed between the two; the lower inverted conical shell is connected to the regular conical shell via corresponding support rods, and a corresponding dust collecting spacing space is formed between the two; the upper inverted conical shell is in contact with the inner wall of the dust collecting cylinder, the material receiving bin is in contact with the inner wall of the dust collecting cylinder, and a bin door that can be opened and closed automatically is provided on the material receiving bin, and the upper inverted conical shell and the material receiving bin allow the dust collecting cylinder to form a closed pressure chamber;

[0016] A separation ring plate is provided on the outer cover of the lower inverted cone-shaped shell, and the separation ring plate separates the pressure chamber into an upper chamber and a lower chamber; the lower chamber is connected to the small passage of the lower layer of the channel, and the upper chamber is connected to the small passage of the upper layer of the cylinder channel;

[0017] When the large fan produces compression work, the air can be further compressed in the upper and lower chambers, so that the pressure difference between the air from the pressure chamber and the negative pressure tube is large, which is conducive to taking away heavier powders; and the amount of air entering the lower chamber is greater than the amount of air entering the upper chamber, which can make the air pressure in the lower chamber greater than the air pressure in the upper chamber, allowing the air to flow better from the lower chamber to the upper chamber.

[0018] As a preferred technical solution of the present application, the forward conical shell is fixed to the inner wall of the dust collecting cylinder via a short cross bar, so that a gap is formed between the forward conical shell and the inner wall of the dust collecting cylinder, allowing the splashed materials from the inverted conical shell to be discharged normally.

[0019] 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.

[0020] As a preferred technical solution of the present application, the large wind turbine is directly placed on the ground via a supporting frame.

[0021] In order to facilitate understanding, the core design points and principles of this scheme are explained: a. Compressed air is generated by arranging a large fan in the middle of the dust collector, and a negative pressure tube with negative pressure is arranged at the upper part of the dust collector, so that the pressure difference between the inlet and outlet air becomes larger, which can improve the wind flow effect; b. The compressed air generated by the large fan is divided into two parts by the air separator seat, and the dust removal chamber is cut up and down by the uppermost inverted cone shell and the receiving bin to form a pressure chamber, so that the compressed air will not be released at the pressure chamber, thereby ensuring the pressure difference between the negative pressure chamber and the negative pressure tube; c. The negative pressure chamber is divided into an upper chamber and a lower chamber by a separating ring plate, so that the amount of air entering the lower chamber is larger than the amount of air entering the upper chamber, so that the pressure generated in the lower chamber is greater than the pressure difference in the upper chamber, which is conducive to the compressed air flowing from the lower chamber-upper chamber-negative pressure tube. Due to the existence of the pressure difference, the powder in the stone particles can be well taken away, achieving an excellent dust removal effect.

[0022] The utility model has the following advantages: good dust removal effect;

[0023] Specifically, the compressed air generated by the large fan is divided by the dividing piece, so that the pressure in the lower chamber of the dust collector is higher than that in the upper chamber. In addition, the upper chamber and the lower chamber together form a pressure chamber, which is closed and only connected to the negative pressure tube. Negative pressure is generated at the negative pressure tube, so that the air will flow violently along the lower chamber-upper chamber-negative pressure tube. The flowing air comes into contact with the material from top to bottom, thereby taking away the powder in the material and achieving a good dust removal effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It should be noted that the directions or positional relationships indicated by "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0033] 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.

[0034] (Example 1)

[0035] See also Figure 1-Figure 4 The wind guide structure for stone material sorting and dust removal includes a dust removal cylinder 300, a large fan 410, and a branch wind cylinder seat 420; wherein the dust removal cylinder 300 is vertically arranged, and the material flows from top to bottom; an air outlet 302 is arranged in the middle of one side of the dust removal cylinder 300, and a branch wind cylinder seat 420 is installed at the air outlet 302, and the branch wind cylinder seat 420 is connected to the large fan 410; and a negative pressure tube 320 is arranged at the upper part of the other side of the dust removal cylinder 300;

[0036] The air distribution cylinder seat 420 has a horizontal cylinder channel, and a plurality of partitions 421 are arranged in the cylinder channel. The partitions 421 divide the cylinder channel into multiple layers of small channels, and the channel space of the multiple small channels gradually decreases from bottom to top.

[0037] During operation, the negative pressure tube 320 generates negative pressure, and the large fan 410 generates compressed air, which enters the dust collector 420. Under the action of the pressure difference, the compressed air can flow from the middle of the dust collector 300 to the upper negative pressure tube 320; and, when the large fan 410 generates compressed air, the compressed air is divided and enters different small channels. The air volume of multiple small channels from bottom to top gradually decreases. When the compressed air flows from the middle of one side of the dust collector 300 to the upper part of the other side, the air in the small channels on the lower layer can assist the air in the small channels on the upper layer to flow, which is more conducive to the air flowing from bottom to top in the dust collector 300; therefore, the air flow in this scheme is strong, which can well take away the powder and dust in the material.

[0038] See also Figure 4 In this embodiment, the number of the dividing piece 421 is one, and the tube is divided into two small channels. The cross-sectional size of the small channel of the upper layer is smaller than the cross-sectional size of the small channel of the lower layer, so that the small channel of the lower layer can divide more air. In addition, the cross-sectional size of the dividing piece 421 is semi-elliptical, so that the two small channels form a large space at the air inlet and a small space at the air outlet, so that the air is further compressed in the corresponding small channel.

[0039] See also Figure 1-Figure 3 In order to allow air to flow better from top to bottom in the dust collection cylinder 300, the structure inside the dust collection cylinder 300 is designed;

[0040] Specifically, the dust collecting cylinder 300 is provided with two inverted cone-shaped shells 310, one positive cone-shaped shell 350, and a material receiving bin 340 at intervals from top to bottom; the upper inverted cone-shaped shell 310 is connected to the lower inverted cone-shaped shell 310 via support rods 311, and a dust collecting spacing space is formed between the two; the lower inverted cone-shaped shell 310 is connected to the positive cone-shaped shell 350 via corresponding support rods 311, and a corresponding dust collecting spacing space is formed between the two; the upper inverted cone-shaped shell 310 is in contact with the inner wall of the dust collecting cylinder 300, and the material receiving bin 340 is in contact with the inner wall of the dust collecting cylinder 300, and a bin door 341 which can be opened and closed automatically is provided on the material receiving bin 340, and the upper inverted cone-shaped shell 310 and the material receiving bin 340 allow the dust collecting cylinder 300 to form a closed pressure chamber 301;

[0041] In addition, a separation ring plate 430 is provided on the outer cover of the lower inverted cone-shaped housing 310, and the separation ring plate 430 divides the pressure chamber 301 into an upper chamber and a lower chamber; the lower chamber is connected to the small channel at the lower layer of the channel, and the upper chamber is connected to the small channel at the upper layer of the cylinder channel;

[0042] During operation, air enters the upper chamber through the small channel of the upper layer and enters the lower chamber through the small channel of the lower layer. Therefore, the amount of air in the lower chamber is greater than that in the upper chamber. Since the upper chamber and the lower chamber are closed, the air can be further compressed in both the lower chamber and the upper chamber, and the pressure of the compressed air in the lower chamber is greater than that in the upper chamber. In this way, a pressure difference is formed between the lower chamber and the upper chamber, and between the upper chamber and the negative pressure tube 320. Moreover, the pressure difference between the upper chamber, the lower chamber and the negative pressure tube 320 is relatively large, so that the compressed air can flow very well from the lower chamber and the upper chamber to the negative pressure tube 320, thereby facilitating the removal of powder and dust with a certain weight in the stone.

[0043] It should be noted that the wind flow coming out of the large fan 410 will enter the inner cavity between the inverted cone shell 310 and the inner wall of the dust removal cylinder 300 after passing through the wind distribution cylinder seat 421, and then be discharged to the negative pressure tube 320 after passing through the dust removal spacing cavity and the inverted cone shell 310; the wind contacts the corresponding stone particles in the dust removal spacing cavity and the inverted cone shell 310, and takes away the powder and dust in the stone particles, thereby playing a role in dust removal and sorting.

[0044] In this embodiment, refer to Figure 3 , the positive cone shell 350 is fixed to the inner wall of the dust collecting cylinder 300 via a short cross bar, so that a gap is formed between the positive cone shell 350 and the inner wall of the dust collecting cylinder 300; the design of the positive cone shell 350 is to support the inverted cone shell 310 on the one hand, and to form a certain degree of compression space between the positive cone shell 350 and the inverted cone shell 310 immediately above it, and the inner wall of the dust collecting cylinder 300 on the other hand - of course, it is inevitable that air will still enter the receiving bin 340. In addition, when dust removal is carried out, it is inevitable that some materials will splash out from the dust removal spacing space - that is, splash out of the inverted cone shell 310 of the next layer, so that these splashed materials can be discharged normally downward from the gap between the positive cone shell 350 and the inner wall of the dust collecting cylinder 300.

[0045] In this implementation, see Figure 3 The 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 in the pressure chamber 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.

[0046] In this embodiment, refer to Figure 1 The large wind turbine 300 is directly placed on the ground via the supporting frame 500 .

[0047] 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.
