Description

Technical Field

[0001] The present invention relates to the technical field of material processing, in particular to a novel material collector. Background Art

[0002] Currently, in some industrial production processes such as cement and lime, material transportation processes must meet high standards. In particular, when conveying powdered materials, these materials are easily scattered on the work site, causing blockages and dust pollution. Existing technologies often use cyclones as devices for material and airflow conveying. However, the space inside the cyclone is very narrow, and when the processing volume is large, it often sticks to the cylinder wall, causing blockage and low dust collection efficiency. Therefore, it is necessary to quickly collect materials during the conveying process and make the material collection process controllable to improve work efficiency.

[0003] The main problems with existing collection devices include: (1) low separation efficiency due to factors such as excessive air flow resistance; (2) inability to adjust the collection method to suit different materials; and (3) failure to effectively consider sealing, which often results in dust leakage and poses a safety hazard.

[0012] In one embodiment, adjacent guide blades form an angle of 15° to 75°, thereby increasing the rotational force while increasing resistance, reducing wind speed, and improving material collection efficiency.

[0013] In one embodiment, the guide cone has different specifications. The greater its height, the better the wind diffusion effect. The greater the angle between the guide blades and the vertical direction, the stronger the rotating flow field.

[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings and examples.

[0026] In order to find a method suitable for efficiently collecting powder materials, the present invention aims to provide a new material collector with high material collection efficiency, and the conveying process of the collector is controllable and adjustable.

[0027] refer to Figure 1 and Figure 2 As shown, the material collector of the present invention mainly includes four parts: an upper cylinder 2, a lower cylinder 5, a lower cone 6, and an inner cylinder 8, which are sealed and connected in sequence, as well as an internal guide cone 4. Among them, the upper cylinder 2 and the inner cylinder 8 are both cylindrical cavity structures, preferably with equal diameters. The lower cylinder 5 is a truncated cone-shaped cavity structure with a top cross-section smaller than the bottom cross-section, while the lower cone 6 is a cavity structure with a top cross-section larger than the bottom cross-section. The inner cylinder 8 is inserted into the cavity of the lower cone 6 from the conical surface of the lower cone 6 and is at a certain distance from the top of the lower cone 6. The cavity part of the present invention is sealed from top to bottom to prevent dust leakage during the material collection process.

[0028] The collector's feed port 1 is located at the top of the upper cylinder 2 for system air intake, the air outlet 9 is located at the bottom of the inner cylinder 8, and the discharge port 7 is located at the bottom of the lower cone 6. The top-in and bottom-out structure can greatly reduce the resistance of the material flow path.

[0029] The guide cone 4 is arranged in the lower cylinder 5, and its main function is to increase the centrifugal force, so that the airflow can form a high-speed rotating flow field on both sides of it. It is a solid frustum or cone structure with a top cross-section smaller than the bottom cross-section, and there is always a gap between it and the inner wall of the lower cylinder 5. On the guide cone 4, multiple guide blades 3 are connected along the circumference to guide the airflow and powder to move downward.

[0030] According to the above structure, during operation, a rotating airflow is used to bring the captured material from the feed port 1 into the upper cylinder 2 of the collector. Subsequently, under the guidance of the guide vanes 3, the airflow is broken up and drives the material to perform a spiral motion, forming a rotating flow field between the guide cone 4 and the lower cylinder 5, thereby enhancing the airflow. At the bottom of the lower cone 6, as the airflow speed decreases, the dust gradually begins to settle and is discharged from the discharge port 7 on the lower cone 6, while the airflow is discharged from the air outlet 9. By entering from the top and exiting from the bottom, and by forming a swirling flow field between the guide cone and the lower cylinder, the present invention can significantly improve the gas-material separation efficiency. Using coal powder as the experimental material, its separation efficiency can reach over 80-90%. At the same time, the resistance is smaller than that of collection equipment such as cyclones, the structure is simple and stable, and the material collection is quick and orderly.

[0031] In some embodiments of the present invention, the upper cylinder 2 and inner cylinder 8 are arranged coaxially and disjointed, i.e., separated by a distance, with the feed inlet 1 and air outlet 9 on the upper cylinder 2 and inner cylinder 8 vertically opposed. This structure enhances cyclonic flow intensity, prevents material accumulation, and improves collection efficiency.

[0032] In some embodiments of the present invention, the guide cone 4 is a conical structure that is closed at the top and bottom, and the bottom surface is fixedly installed in the lower cylinder 5 by means of interlocking, bolts, etc., and is detachable. Specifically, a number of brackets or meshes can be first installed on the bottom surface of the lower cylinder 5, and the bottom surface of the guide cone 4 can be fixed to the brackets or meshes by means of bolts, etc. The gap between the guide cone 4 and the inner wall of the lower cylinder 5 is used to guide the inlet airflow. Generally, the greater the height of the guide cone 4, the better the wind diffusion effect, but excessive length will increase the wind resistance of the equipment. Therefore, a balance should be struck between the diffusion effect and the wind resistance. In this embodiment, the guide cone 4 is slightly lower than the lower cylinder 5.

[0033] In some embodiments of the present invention, guide vanes 3 are generally installed in the upper-middle portion of guide cone 4, evenly spaced along one or more circumferential directions. Preferably, individual guide vanes 3 are fan-shaped and fixed to the outer wall of guide cone 4 to guide airflow and material flow. They can be integrally designed and manufactured with guide cone 4, or they can be removably installed.

[0034] An included angle of 15° to 75° is formed between adjacent guide blades 3. This angle range can further increase the rotational force while increasing resistance, reducing wind speed, and improving material collection efficiency.

[0035] The guide cone 4 of the present invention is available in various sizes, and the guide vanes 3 thereon are also available in a variety of sizes. Generally, the angle of the guide vanes 3 can be adjusted to control the intensity of the rotating flow field, thereby adjusting the collection efficiency. The larger the angle between the guide vanes 3 and the vertical direction, the stronger the rotating flow field and the better the collection effect.

[0036] In some embodiments of the present invention, an inlet connection flange is provided at the top of the upper cylinder 2, and outlet connection flanges are provided at the bottoms of the lower cone 6 and the inner cylinder 8. Connection flanges are provided between the connections of each cylinder. Thus, the inlet connection flange of the upper cylinder 2 is connected to the feed port 1, and the lower end is sealed to the lower cylinder 5 via the connection flange. The lower end of the lower cylinder 5 is sealed to the lower cone 6 via the connection flange.

[0037] In some embodiments of the present invention, the cross-section of the lower cone 6 is circular or elliptical, with the angle between the generatrix and the horizontal line being 40° to 60°; the inner cylinder 8 is a cylinder with a circumferential radius smaller than the upper circumferential radius of the lower cone 6. The inner cylinder 8 communicates with the inner cavity of the lower cone 6 and is coaxial with the lower cone 6. This design prevents separated particles from entering the inner cylinder. Under the action of centrifugal force and gravity, the solid particles are thrown to the side walls for separation. The separated particles are discharged from the bottom outlet of the lower cone 6, and the airflow forms a high-speed cyclone and is discharged from the inner cylinder.

[0038] In some embodiments of the present invention, the distance between the inner cylinder 8 and the lower cylinder 5 should be set moderately, generally equal to the inner radius of the inner cylinder 8. If it is too long, the wind speed will be too high, and the airflow will have difficulty entering the inner cylinder. If it is too short, the resistance will be too small, and large particles will also enter the inner cylinder 8 with the airflow, and a good separation effect cannot be obtained.

[0039] In some embodiments of the present invention, the inner cylinder 8 and the lower cylinder 5 are arranged coaxially, but are not connected. A distance is set in the middle. The airflow generates centrifugal force during the rotation process to form a high-speed cyclone, and the airflow speed is reduced when it hits the wall of the inner cylinder 8. The airflow in the lower cone 6 will decelerate after a circle of rotation and be sent out of the air outlet 9, thereby achieving gas-solid separation.

[0040] In some embodiments of the present invention, the lower cylinder 5 has a relatively slightly convex shape, that is, the diameter of the cylinder decreases and then increases from top to bottom, preferably in an arc-shaped transition, with a limited portion of the decrease. After passing through the portion of the decrease, the diameter of the cylinder rapidly increases. Under the action of centrifugal force, the material is thrown into the slightly convex lower cylinder 5. The configuration of the lower cylinder 5 allows the particulate material to continuously impact the cylinder wall as it rotates downward with the airflow, thereby moving downward along the wall. The lower cone 6 has a downwardly conical lower cylinder. Under the action of gravity, the material is gathered into the constriction of the discharge port 7 and collected. The constriction design also prevents the particles near the discharge port from mixing back.

[0041] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the present profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
