Description

[0002] In modern industrial production, especially in the fields of chemical, pharmaceutical, food processing, electric power and environmental protection, the separation of gas-solid or gas-liquid two-phase flow is a vital process. As a classic and widely used separation equipment, the basic principle of cyclone separator relies on the centrifugal force generated by the rotating airflow to achieve the separation of particles and fluids. However, traditional cyclone separators often face the contradiction between separation efficiency and airflow resistance. That is, in order to obtain higher separation efficiency, stronger rotating airflow is usually required, and the enhancement of airflow will produce stronger eddy currents, turbulence and other phenomena in the equipment, which inevitably leads to higher pressure loss, thereby increasing energy consumption and operating costs. If the airflow intensity is reduced, it will lead to the inability to provide sufficient centrifugal force for solid particles. Summary of the invention

[0005] When the middle cylinder rotates, the middle tube, the connecting arm, the supporting shaft and the fan blades rotate synchronously.

[0006] Furthermore, a wind shield ring is arranged on the outer wall of the upper tube in the upper cylinder, and the circumferential outer wall of the wind shield ring is composed of a cylindrical part located on the upper side and a conical part located on the side.

[0007] Furthermore, the number of the air intake pipes is set to be multiple, and the shape of the air intake pipes is arc-shaped, and the connection position between the air intake pipes and the upper tube is along the tangential direction of the inner wall of the upper tube.

[0008] Furthermore, the bottom of the middle tube is configured as a closing area.

[0009] Furthermore, a filter disc is arranged in the collection barrel, a column is arranged at the bottom of the filter disc, and the filter disc rotates on the column, the column is fixed in the collection barrel, the axis of the column and the axis of the intermediate tube deviate from each other, an auxiliary ring is connected to the bottom of the intermediate tube, the bottom of the auxiliary ring is eccentrically buckled on the filter disc, and the intermediate tube rotates on the auxiliary ring;

[0010] The filter disc is conical in shape, and the filter disc positions the auxiliary ring through its shape, so that the auxiliary ring cannot rotate on its own.

[0011] Furthermore, a first transmission ring is arranged on the outer wall of the intermediate tube, a second transmission ring is arranged on the transmission sleeve outside the first transmission ring, and the second transmission ring is fixed on the filter disc through a plurality of connecting rods.

[0012] Furthermore, a sleeve is provided in the collecting barrel, the sleeve is located outside the filter disc, and the sleeve is coaxial with the middle barrel. The bottom of the sleeve is fixed in the collecting barrel, and a collection channel is formed between the top of the sleeve and the inner wall of the collecting barrel.

[0013] Furthermore, the bottom surface of the collecting barrel is inclined, and two material ports are provided on the bottom surface of the collecting barrel, and the two material ports are respectively connected to the inner and outer side spaces of the sleeve, and a material discharge structure is provided on the bottom surface of the collecting barrel;

Since the middle cylinder is in an active rotating state, its relative rotation speed is higher than that of the airflow. At this time, the inner wall of the middle cylinder will not hinder the flow of the airflow, but will instead generate friction to assist the airflow, thereby enhancing the rotational flow effect of the gas and achieving the dual goals of reducing drag and increasing efficiency.

[0020] The use of suction can greatly reduce the loss of kinetic energy of airflow, which can increase the gas flow speed and thus enhance the separation effect. The enhanced rotating airflow can provide sufficient centrifugal force to effectively separate the particles and drop them along the inner wall of the middle tube to the collection container;

[0021] In summary, this technical solution effectively solves the contradiction between efficiency and resistance faced by traditional cyclone separators through innovative design, providing a more efficient, energy-saving and environmentally friendly separation solution for industrial production.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0034] like Figures 1 to 4As shown, the high-efficiency and low-resistance cyclone separator with integrated drag reduction and efficiency enhancement mechanism of the present invention comprises an upper cylinder 1, a middle cylinder 2 and a collecting barrel 3 arranged in sequence from top to bottom, the upper cylinder 1, the middle cylinder 2 and the collecting barrel 3 are connected to each other, the upper cylinder 1 and the collecting barrel 3 are fixed in position, the middle cylinder 2 rotates between the upper cylinder 1 and the collecting barrel 3, the collecting barrel 3 is used to collect the separated particulate matter, the upper cylinder 1 is connected with a plurality of air inlet pipes 4 for supplying air to the upper cylinder 1, an intermediate tube 5 is coaxially arranged in the middle of the middle cylinder 2, the bottom of the intermediate tube 5 is inserted into the collecting barrel 3, an upper tube 6 is connected with the top of the intermediate tube 5, the top of the upper tube 6 passes through the upper cylinder 1 and extends out, the intermediate tube 5 and the middle cylinder 2 are connected by a plurality of connecting arms 7, a support shaft 8 is arranged in the upper tube 6, a plurality of fan blades 9 are arranged on the outer wall of the support shaft 8, and the bottom of the support shaft 8 is fixed to the inner wall of the intermediate tube 5;

[0035] When the middle cylinder 2 rotates, the intermediate tube 5, the connecting arm 7, the supporting shaft 8 and the fan blades 9 rotate synchronously.

[0036] In detail, the positions of the upper cylinder 1, the collecting barrel 3, the air inlet pipe 4 and the upper tube 6 are fixed, the middle cylinder 2, the intermediate tube 5, the connecting arm 7, the supporting shaft 8 and the fan blades 9 are rotatable, and the plurality of fan blades 9 are rotated in the upper tube 6, so that the air in the upper tube 6 can flow by using the fan blades 9, the upper cylinder 1 and the middle cylinder 2 are used to provide space for the cyclonic separation of particulate matter and air, the collecting barrel 3 is used to collect the separated particulate matter, the air inlet pipe 4 is used to supply gas to enter the upper cylinder 1 and the middle cylinder 2, the intermediate tube 5 is installed on the middle cylinder 2 through a plurality of connecting arms 7, and the middle cylinder 2 can drive the intermediate tube 5 to rotate, and the intermediate tube 5 is docked with the upper tube 6 and rotates relatively.

[0037] When in use, the middle cylinder 2 can be driven to rotate by an external motor, and the middle cylinder 2 will drive the intermediate tube 5, the connecting arm 7, the supporting shaft 8 and the fan blades 9 on it to rotate. The multiple fan blades 9 can promote the gas flow in the upper tube 6, so that the upper tube 6 extracts the air in the middle cylinder 2 through the intermediate tube 5, and a negative pressure is formed inside the middle cylinder 2. The external dust-containing gas is sucked into the upper cylinder 1 and the middle cylinder 2 by the air inlet pipe 4. As the middle cylinder 2, the intermediate tube 5 and the multiple connecting arms 7 rotate, the air in the middle cylinder 2 rotates, that is, the gas performs a swirl motion. At this time, the inner wall of the middle cylinder 2 will not cause friction obstruction to the flow of the gas, but will provide friction for the gas. The flow provides power, thereby achieving the effect of reducing resistance and increasing efficiency of gas flow, making it convenient for the gas to quickly rotate and flow along the inner wall of the middle tube 2, and because of the use of suction, the eddy and turbulence phenomena generated by the airflow when entering the upper tube 1 and the middle tube 2 can be reduced. Therefore, by using this method, energy consumption and operating costs can be reduced while enhancing the gas flow intensity. The rotating airflow in the middle tube 2 performs centrifugal motion, and the particles in the airflow are centrifuged and fall down along the inner wall of the middle tube 2 into the collecting barrel 3 for aggregation, while the airflow flows upward in the opposite direction through the bottom of the intermediate tube 5 and is discharged through the upper tube 6, thereby achieving the purpose of cyclone separation.

[0038] It should be pointed out that the conventional cyclone separator mainly uses an air pump to provide a driving force for the airflow, while in this case, the rotation of the fan blades 9 is used to extract air, which can also realize the cyclone work of the gas.

[0039] By adopting active suction instead of forced air supply, the eddy and turbulence phenomena generated by the airflow entering the equipment can be reduced, thereby reducing the kinetic energy loss of the airflow. Since the middle cylinder 2 is in an active rotation state, its rotation speed relative to the airflow is higher. At this time, the inner wall of the middle cylinder 2 will not hinder the flow of the airflow, but will instead produce friction to the airflow, thereby enhancing the rotational flow effect of the gas and achieving the dual goals of reducing resistance and increasing efficiency. The use of suction can greatly reduce the kinetic energy loss of the airflow, which can enhance the gas flow speed and thus enhance the separation effect. The enhanced rotating airflow can provide sufficient centrifugal force to effectively separate the particles and fall along the inner wall of the middle cylinder 2 to the collection container 3. In summary, this technical solution effectively solves the contradiction between efficiency and resistance faced by traditional cyclone separators through innovative design, and provides a more efficient, energy-saving and environmentally friendly separation solution for industrial production.

[0040] like Figure 3 to Figure 4 As shown, a wind shield ring 10 is arranged on the outer wall of the upper tube 6 in the upper cylinder 1, and the circumferential outer wall of the wind shield ring 10 is composed of a cylindrical part located on the upper side and a conical part located on the side.

[0041] In detail, the gas entering the upper cylinder 1 through the air intake pipe 4 flows between the inner wall of the upper cylinder 1 and the cylindrical part of the wind shield ring 10. At this time, the area between the inner wall of the upper cylinder 1 and the cylindrical part of the wind shield ring 10 constitutes an air guide space, so that the gas rotates and flows near the inner wall of the upper cylinder 1. This can not only increase the distance between the airflow and the axis of the upper cylinder 1, that is, the centrifugal radius of the airflow, but also gather the airflow, thereby reducing the eddy and turbulence of the airflow, and making it convenient for the airflow entering the upper cylinder 1 to quickly form a swirl effect, thereby reducing the gas energy loss and facilitating the rapid shaping of the airflow. This method can achieve the effects of deceleration and efficiency improvement at the same time.

[0042] When the airflow flows downward in the vertical direction, the conical portion on the lower side of the wind shield ring 10 can achieve a transition effect on the airflow, thereby avoiding the airflow from being scattered and causing a large loss of kinetic energy of the airflow due to sudden changes in space, and facilitating the airflow to gradually adapt to the space changes in the cyclone separator.

[0043] like Figure 3 As shown, the number of the air intake pipes 4 is set to be multiple, and the shape of the air intake pipe 4 is arc-shaped, and the connection position between the air intake pipe 4 and the upper tube 1 is along the tangential direction of the inner wall of the upper tube 1.

[0044] In detail, by limiting the shape and installation method of the air inlet pipe 4, a rotational momentum can be applied to the airflow entering the upper cylinder 1 and the middle cylinder 2 in advance, so that the airflow has a certain directional rotational flow when entering the device, so that the airflow can form a stable vortex more quickly when entering the upper cylinder 1 and the middle cylinder 2, reducing the kinetic energy loss in the process of forming the vortex.

[0045] By setting up multiple air inlet pipes 4, the kinetic energy of the airflow entering the upper tube 1 and the middle tube 2 can be evenly distributed, avoiding the local high turbulence area phenomenon caused by using a single air inlet pipe 4, and also making the gas flow field in the entire device more stable.

[0046] like Figure 3 As shown, the bottom of the middle tube 2 is configured as a closing area 11 .

[0047] In detail, when the airflow rotates and flows downward in the middle tube 2, the radius of the closing area 11 becomes smaller as it goes downward, so the rotation speed of the airflow becomes faster in the horizontal direction, thereby increasing the moving speed and centrifugal effect of the particles, making it convenient for the particles to be quickly thrown out and away from the middle tube 5 when entering the collection barrel 3, thereby achieving rapid and effective separation of the particles and the airflow.

[0048] like Figures 4 to 5 As shown, a filter disc 12 is arranged in the collecting barrel 3, a column 13 is arranged at the bottom of the filter disc 12, and the filter disc 12 rotates on the column 13, the column 13 is fixed in the collecting barrel 3, the axis of the column 13 deviates from the axis of the intermediate tube 5, an auxiliary ring 14 is connected to the bottom of the intermediate tube 5, the bottom of the auxiliary ring 14 is eccentrically buckled on the filter disc 12, and the intermediate tube 5 rotates on the auxiliary ring 14;

[0049] The filter disc 12 is conical in shape, and the filter disc 12 positions the auxiliary ring 14 by its shape, so that the auxiliary ring 14 cannot rotate by itself.

[0050] In detail, the filter disc 12 is installed on the collecting barrel 3 through the column 13, and the rotation axis of the filter disc 12 is located outside the intermediate tube 5. Since the filter disc 12 is conical in shape, when the auxiliary ring 14 is buckled on the filter disc 12, the upper surface of the filter disc 12 can use its shape to position the auxiliary ring 14, so that the auxiliary ring 14 cannot rotate with the intermediate tube 5. Therefore, the auxiliary ring 14 can be used to achieve the connection between the filter disc 12 and the intermediate tube 5.

[0051] The gas entering the collection barrel 3 can flow to the bottom of the filter disc 12 and pass through the filter disc 12 in the reverse direction to enter the intermediate tube 5. The filter disc 12 filters the gas, thereby improving the gas separation purity. The filter disc 12 is rotated and the filter disc 12 slides on the auxiliary ring 14. The part of the column 13 at the bottom of the auxiliary ring 14 that is in the filtering work is transferred to the outside of the auxiliary ring 14, and the other parts on the column 13 are transferred to the bottom of the auxiliary ring 14 and continue to filter. The part of the column 13 that moves outside the auxiliary ring 14 is blown by the downward airflow in the collection barrel 3, so that the particulate matter that blocks the filter holes on the filter disc 12 on the bottom of the filter disc 12 is cleaned by the airflow. Since the filter disc 12 is conical in shape, the particulate matter deposited on the upper surface of the filter disc 12 can be automatically blown away by the airflow, thereby ensuring the long-term and stable air permeability function of the filter disc 12.

[0052] like Figure 5 As shown, a first transmission ring 15 is arranged on the outer wall of the intermediate tube 5 , a second transmission ring 16 is arranged on the outer transmission sleeve of the first transmission ring 15 , and the second transmission ring 16 is fixed on the filter disc 12 through a plurality of connecting rods 17 .

[0053] In detail, when the middle pipe 5 rotates, it can drive the second transmission ring 16 to rotate through the first transmission ring 15 , and the second transmission ring 16 can drive the filter plate 12 to rotate through a plurality of connecting rods 17 , thereby providing power for the filter plate 12 .

[0054] like Figure 3 As shown, a sleeve 18 is provided in the collecting barrel 3, the sleeve 18 is located outside the filter disc 12, and the sleeve 18 is coaxial with the middle barrel 2. The bottom of the sleeve 18 is fixed in the collecting barrel 3, and a collection channel is formed between the top of the sleeve 18 and the inner wall of the collecting barrel 3.

[0055] In detail, by setting the sleeve 18, the internal space of the collection barrel 3 can be divided into two areas, inner and outer. In this way, when the particles are centrifugally thrown into the collection barrel 3, the particles with larger volumes can move through the aggregation channel to the internal space of the collection barrel 3 outside the sleeve 18, while the particles with smaller volumes gather in the sleeve 18, thereby achieving the classification of the particles.

[0056] In actual use, the number of sleeves 18 can be set to multiple, so as to achieve multi-level classification of particulate matter, and multiple sleeves 18 are sequentially installed, and the height of the sleeves 18 gradually decreases from the outside to the inside.

[0057] like Figure 6 As shown, the bottom surface of the collecting barrel 3 is inclined, and two material ports are provided on the bottom surface of the collecting barrel 3. The two material ports are respectively connected to the inner and outer side spaces of the sleeve 18, and a discharge structure is provided on the bottom surface of the collecting barrel 3;

[0058] The discharge structure includes a fan-shaped groove plate 19 fixed to the bottom of the collection barrel 3, the fan-shaped groove plate 19 is buckled on the outside of multiple material ports, a rotating ring 20 is rotatably arranged at the bottom of the collection barrel 3, the rotating ring 20 passes through the fan-shaped groove plate 19, two groups of collection areas are arranged on the rotating ring 20, each group of collection areas is composed of multiple receiving ports 21, and the multiple receiving ports 21 in each group of collection areas are distributed in an annular shape, and the two groups of collection areas correspond to two material ports respectively. When the rotating ring 20 rotates, at least one of the multiple receiving ports 21 in the collection area corresponding to the material port is located in the fan-shaped groove plate 19, and a material guide plate 22 is arranged at the end of the fan-shaped groove plate 19, and two material channels are opened on the material guide plate 22;

[0059] The rotating ring 20 is powered by a first motor 23 and a first transmission wheel 24 .

[0060] In detail, since the bottom surface of the collecting barrel 3 is inclined, it is convenient for the particles to gather at the material port, and the particles fall into the receiving port 21 through the material port. The bottom of the fan-shaped groove plate 19 blocks the bottom of the receiving port 21. When the rotating ring 20 rotates, the receiving port 21 carries the particles therein and moves toward the guide plate 22. When the receiving port 21 moves out of the fan-shaped groove plate 19, the particles naturally fall onto the guide plate 22 and are discharged through the material channel on the guide plate 22. The two material channels correspond to two groups of collection areas respectively, so that the discharge of particles can be realized, and this method can ensure that the collecting barrel 3 and the outside air will not circulate with each other, thereby preventing the outside air from entering the collecting barrel 3 through the material port and affecting the normal cyclone separation work.

[0061] The first motor 23 is fixed at the bottom of the collecting barrel 3 , the first transmission wheel 24 is installed at the output end of the first motor 23 , and the first transmission wheel 24 is transmission-connected to the rotating ring 20 .

[0062] like Figure 2 As shown, the upper cylinder 1 and the collecting barrel 3 are connected via a plurality of side plates 25;

[0063] A third transmission ring 26 is disposed on the outer wall of the middle tube 2 . A second transmission wheel 27 is provided on the third transmission ring 26 . The second transmission wheel 27 is powered by a second motor 28 . The second motor 28 is mounted on the side plate 25 .

[0064] In detail, the side plate 25 can be connected to the upper cylinder 1 and the collecting barrel 3, and the second motor 28 can drive the middle cylinder 2 to rotate through the second transmission wheel 27 and the third transmission ring 26, thereby providing power for the device.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
