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.

[0033] like Figures 1 to 5 As shown, the high-efficiency low-resistance separator drag reduction device of the present invention is used to reduce the drag of the fluid in the separator body 1;

[0034] The invention comprises a drag reduction structure 2 arranged in a separator body 1, wherein the drag reduction structure 2 consists of an outer cylinder 3 and an inner cylinder 4, both of which are located on the inner side of the separator body 1, and the outer cylinder 3 is located on the outer side of the inner cylinder 4, and the space between the outer cylinder 3 and the inner cylinder 4 is used for fluid flow, and the outer cylinder 3 and the inner cylinder 4 are connected by a connecting frame 5, and a plurality of guide plates 6 are arranged on the inner wall of the outer cylinder 3, and the guide plates 6 are spiral in shape, and the cross-sectional shape of the guide plates 6 is a right angle, and the guide plates 6 form a groove with the inner wall of the outer cylinder 3, and when the fluid flows between the outer cylinder 3 and the inner cylinder 4, the fluid will drive the outer cylinder 3 and the inner cylinder 4 to rotate.

[0035] Detailed, such as Figure 4 As shown, the inner tube 4 is rotatably mounted on the vertical tube on the separator body 1. Figure 2 As shown, the outer cylinder 3 is rotatably arranged on the inner wall of the separator body 1, and the space between the outer cylinder 3 and the inner cylinder 4 is available for fluid flow, a plurality of connecting frames 5 are located on the lower side of the separator body 1, and the connecting frames 5 are used to connect the outer cylinder 3 and the inner cylinder 4, and a plurality of guide plates 6 are fixed on the inner wall of the outer cylinder 3, and the overall shape of the guide plate 6 is spiral, and the vertical cross-sectional shape of the guide plate 6 is right-angled, so that the guide plate 6 and the inner wall of the outer cylinder 3 can form a groove shape, and the groove-like structure can be set as a collection groove, and the overall shape of the collection groove is spiral, and a large space is left between the guide plate 6 and the inner cylinder 4.

[0036] When the fluid and the particulate impurities therein are separated, the fluid is supplied tangentially to the separator body 1, and the fluid performs a swirling motion in the separator body 1. At this time, the fluid mainly moves between the outer cylinder 3 and the inner cylinder 4. Due to the centrifugal effect of the fluid, the particulate impurities in the fluid move toward the inner direction of the outer cylinder 3. At this time, the particulate impurities and part of the fluid will act on the guide plate 6, so that the guide plate 6 is used to rotate the outer cylinder 3, the inner cylinder 4 and the connecting frame 5. At this time, the outer cylinder 3, the inner cylinder 4 and the fluid are all in a rotating state, so that the speed difference between the outer cylinder 3 and the inner cylinder 4 and the fluid is reduced, thereby reducing the friction loss between the fluid and the outer cylinder 3 and the inner cylinder 4, and reducing the friction The resistance of the fluid, at the same time, because the particulate impurities move near the inner wall of the outer cylinder 3, the particulate impurities enter the guide plate 6 and gather, at this time, the guide plate 6 blocks the particulate impurities, thereby reducing the movement speed of the particulate impurities relative to the outer cylinder 3, further reducing the wear and damage of the particulate impurities to the outer cylinder 3, and at the same time, the outer cylinder 3 and the guide plate 6 can absorb and utilize the kinetic energy of the particulate impurities to avoid energy loss, by making the outer cylinder 3, the inner cylinder 4 and the fluid move synchronously and reducing the movement speed difference between the fluid and the outer cylinder 3 and the inner cylinder 4, and at the same time using multiple guide plates 6 to block and slow down the particulate impurities and part of the fluid close to the inner wall of the outer cylinder 3. By using these two methods, the friction resistance can reduce the swirl obstruction of the fluid, achieving the drag reduction effect on the fluid, and the guide plate 6 can collect and separate the particulate impurities for diversion processing, so as to facilitate the separation of the particulate impurities and the fluid, and realize efficient and rapid separation.

[0037] In actual use, a motor can also be used to provide auxiliary power for the rotation of the outer cylinder 3. At this time, the rotation speed of the outer cylinder 3 needs to be greater than the swirl speed of the fluid. In this way, the friction between the outer cylinder 3 and the inner cylinder 4 can be used to provide auxiliary power for the swirl motion of the fluid instead of resistance.

[0038] By utilizing the fluid to enable the outer cylinder 3 and the inner cylinder 4 to rotate with the fluid, the speed difference between the fluid and the outer cylinder 3 and the inner cylinder 4 is reduced, and the friction between the fluid and the equipment is reduced. At the same time, the guide plate 6 can be used to block the particle impurities, thereby having a deceleration effect on the particle impurities, further reducing the relative speed between the particle impurities and the outer cylinder 3, and conveniently reducing the friction loss of the particle impurities on the outer cylinder 3, thereby improving the overall efficiency of the system; the guide plate 6 can be used to collect the energy of the centrifugal rotation of the particle impurities, thereby facilitating the conversion of energy, reducing energy loss, and facilitating the rotation of the outer cylinder 3 and the inner cylinder 4. The spiral guide plate 6 can effectively collect and separate particulate impurities in the fluid, and use centrifugal force to make the impurities gather in the groove; when the fluid enters the separator body 1 and drives the outer cylinder 3 and the inner cylinder 4 to rotate, the dynamic balance between the outer cylinder 3, the inner cylinder 4 and the fluid helps to maintain the stable swirl state of the fluid, reduces the generation of turbulence, and further reduces the resistance; In summary, the high-efficiency and low-resistance separator drag reduction device not only solves the high resistance problem of traditional cyclone separators through a series of innovative designs, but also significantly improves the separation efficiency and energy utilization rate, reduces maintenance costs, and is an ideal choice for achieving energy conservation and emission reduction and improving production efficiency in industrial production.

[0039] like Figure 5 As shown, a right-angled side of the cross section of the guide plate 6 is fixed on the inner wall of the outer cylinder 3 , and a retaining edge 7 is provided on the other right-angled side of the cross section of the guide plate 6 , which is inclined toward the inner side of the guide plate 6 .

[0040] In detail, by setting the retaining edge 7, the particulate impurities collected in the guide plate 6 can be conveniently blocked to prevent the fluid from entering the guide plate 6 to flush the impurities out and re-mixing them into the fluid, thereby facilitating the collection of impurities. Since the retaining edge 7 is inclined, the particulate impurities in the centrifugal state can be conveniently guided, thereby facilitating the impurities to enter the guide plate 6 quickly and smoothly.

[0041] like Figure 5 As shown, a feed pipe 9 is provided on the top of the separator body 1, a drainage slot plate 8 is provided between the outer cylinder 3 and the inner cylinder 4, the feed pipe 9 is connected with the drainage slot plate 8, and the drainage slot plate 8 is fixed on the separator body 1;

[0042] Wherein, the drainage slot plate 8 is in a spiral shape.

[0043] In detail, the external fluid can be supplied into the space between the outer cylinder 3 and the inner cylinder 4 in the separator body 1 through the feed pipe 9. In order to avoid the fluid from contacting the inner wall of the separator body 1 when entering the separator body 1, the top of the outer cylinder 3 and the top of the inner cylinder 4 can be made to contact the top of the inner wall of the separator body 1. At this time, the feed pipe 9 needs to be installed obliquely on the top of the separator body 1, and the drainage groove plate 8 is used to divert the fluid discharged from the feed pipe 9, so that the fluid flows along the inner wall of the outer cylinder 3, so that the fluid forms a vortex state. The fluid guided by the drainage groove plate 8 can quickly change its flow state, thereby reducing the risk of eddy currents or turbulences generated after the fluid enters the separator body 1.

[0044] like Figure 5 As shown, a plurality of horizontal advection fan plates 10 are arranged on the outer wall of the inner tube 4 .

[0045] In detail, by setting up the horizontal flow fan plate 10, the straight flow of the fluid in the vertical direction can be conveniently blocked, thereby preventing the fluid entering the separator body 1 from flowing directly toward the bottom opening of the vertical tube on the separator body 1, avoiding the short-circuit flow of the fluid downward, and making it convenient for the fluid to fully swirl in the separator body 1. At the same time, the horizontal flow fan plate 10 will not hinder the horizontal swirl movement of the fluid, and the flow of the fluid in the vertical direction can be achieved in the gap between two adjacent horizontal flow fan plates 10.

[0046] like Figure 3 As shown, an annular groove 11 is provided on the outer wall of the outer cylinder 3 , and the annular groove 11 is composed of a plurality of V-shaped grooves connected end to end. A shifting post 12 is slidably provided in the annular groove 11 , and the shifting post 12 is fixed on the separator body 1 .

[0047] In detail, when the outer cylinder 3 rotates, the annular groove 11 on the outer cylinder 3 will slide relative to the lever 12. Since the annular groove 11 is composed of a plurality of V-shaped grooves, the lever 12 will push the outer cylinder 3 to vibrate in the vertical direction, thereby preventing particulate impurities from being adsorbed and deposited on the outer cylinder 3 or the inner cylinder 4, making it easier to remove the impurities, and preventing the adsorption of impurities from affecting the smoothness of the surfaces of the outer cylinder 3 and the inner cylinder 4.

[0048] like Figure 2 and Figure 6 As shown, a partition 13 is provided at the bottom of the outer cylinder 3, and the partition 13 is connected to the separator body 1 through a plurality of fixing plates 15, and a cone hopper 14 is provided at the bottom of the partition 13;

[0049] An isolation channel 16 is formed between the outer wall of the partition 13 and the inner wall of the separator body 1 .

[0050] In detail, the particulate impurities collected by the guide plate 6 fall into the isolation channel 16, so that the isolation channel 16 can be used to separate the particulate impurities from the fluid, thereby achieving the guidance of the particulate impurities. The particulate impurities fall onto the cone bucket 14 and slide along the inclined surface of the cone bucket 14 into the ash hopper set at the bottom of the separator body 1, thereby preventing the particulate impurities from being mixed with the fluid again after being discharged by the guide plate 6. The fixed plate 15 can support the partition tube 13.

[0051] like Figure 6 As shown, a slow flow chamber 17 is provided at the bottom of the cone bucket 14, and an opening is provided in the middle of the top of the slow flow chamber 17, and fluid is supplied to enter the slow flow chamber 17 through the opening, and a separation channel 18 is formed between the slow flow chamber 17 and the cone bucket 14;

[0052] The inner wall of the partition 13 is set to be conical, and the inner space of the slow flow chamber 17 provides a slow flow space for the separated fluid.

[0053] In detail, since the shape of the inner wall of the partition 13 is conical, when the fluid flows downward, as the diameter of the inner wall of the partition 13 decreases, the fluid flow rate increases, and the centrifugal effect of smaller particle impurities in the fluid is enhanced. When the fluid moves to the position of the separation channel 18, this part of the smaller particle impurities can be centrifuged into the separation channel 18 and enter the ash hopper set at the bottom of the separator body 1 through the separation channel 18, thereby utilizing the enhanced centrifugal effect to separate the smaller particle impurities, further improving the separation effect.

[0054] The bottom of the vertical tube on the separator body 1 can be inserted into the slow flow chamber 17 through the top opening of the slow flow chamber 17. The separated fluid will enter the slow flow chamber 17 through the gap between the opening and the outer wall of the vertical tube on the separator body 1. The internal space of the slow flow chamber 17 is relatively large, which can slow down the fluid flow rate, facilitate reducing the fluid flow rate at the bottom opening of the vertical tube, reduce the possibility of secondary entrainment, and reduce the resistance of the fluid when leaving the separator.

[0055] like Figure 6 As shown, a cone 19 is provided in the slow flow chamber 17, and the inner wall cross section of the slow flow chamber 17 is arc-shaped.

[0056] In detail, the cone 19 is fixed at the bottom of the inner wall of the slow flow chamber 17. When the fluid enters the slow flow chamber 17, since the cross-sectional shape of the inner wall of the slow flow chamber 17 is arc-shaped, it can guide the fluid. At the same time, the cone 19 can smoothly change the flow direction of the fluid in the slow flow chamber 17, so that the fluid flows upward in the opposite direction and enters the vertical pipe on the separator body 1, thereby reducing the resistance when the fluid is discharged.

[0057] 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.
