Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a cyclone separator. Background Art

[0002] Cyclone separators are often used in industry to process gas-solid systems. They rely on the rotational motion caused by the tangential introduction of airflow to throw solid particles or liquid droplets with large inertial centrifugal force toward the outer wall to separate them.

[0003] According to the publication (announcement) number: CN107511272B, the publication (announcement) date: 2024-07-02, a cyclone separator is disclosed.

[0004] In the prior art including the above-mentioned patents, the particle sizes in the impurity-containing gas are usually uneven. The larger particles of impurities will fall and be collected by themselves after being thrown to the wall of the device by the external vortex, while the smaller particles of impurities will remain suspended and be carried out of the separator by the upward internal vortex. Impurities between the two particle sizes will generally fall gradually downward under the combined action of centrifugal force and gravity. However, the gradual falling of these impurities will inevitably affect the original separation of large particles and small particles, and will also be carried out by the internal vortex, thereby affecting the purity of the gas discharged from the separator and reducing the working efficiency of the cyclone separator.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, a cyclone separator comprises a separation cylinder 1 provided with an air inlet 11 and an air outlet 12, and further comprises an isolation cylinder 2 provided in the separation cylinder 1, wherein a conveying sheet 21 is arranged on the circumference of the end of the isolation cylinder 2;

[0025] A double-pointed block 4 coaxially arranged with the air outlet 12 is provided in the isolation tube 2 , and a plurality of storage boxes 3 are movably provided on the isolation tube 2 , and the openings of the storage boxes 3 in a default state face toward the double-pointed block 4 .

[0026] Specifically, the air inlet 11 and the air outlet 12 of the separation cylinder 1 are of existing design and will not be described in detail here. The isolation cylinder 2 is formed by a combination of a cylindrical cylinder and an inverted conical cylinder. The purpose is to make the two shapes of cylinders adapt to the shape of the separation cylinder 1 to avoid interference with the formation of internal and external vortexes.

[0027] Furthermore, the upper end of the isolation tube 2 is higher than the lower end of the gas outlet 12, and the double-pointed block 4 is formed by connecting the bottom surfaces of two conical blocks so that the two pointed cones face upward and downward respectively.

[0028] In the process of conveying impurities downward through the external vortex, it is guided by the side wall of the isolation cylinder 2, and the airflow begins to separate when it reaches the position of the conveying sheet 21, so that the impurities that pass through the gap of the conveying sheet 21 and enter the internal vortex are not easy to return to the external vortex, thereby realizing the preliminary separation and processing of medium-sized particles, that is, the medium-sized particles in the external vortex can only be gathered and conveyed downward, while the medium-sized particles in the internal vortex can only be discharged upward, but before being discharged upward, they will contact the lower end face of the double-pointed block 4, so that the medium-sized particles and small-sized impurities are intercepted, and a downward circulation surge occurs, so that these particles are forced downward and enter the storage box 3 for storage, thereby reducing the impurity content discharged from the air outlet 12 and improving the processing efficiency of the cyclone separator.

[0029] As an embodiment further provided by the present invention, the isolation cylinder 2 divides the separation cylinder 1 to form an outer flow channel 24 and an inner flow channel 25 , and the inner flow channel 25 is connected to the matching storage box 3 .

[0030] Specifically, the outer flow channel 24 is used for circulating the outer vortex flow, and the inner flow channel 25 is used for circulating the inner vortex flow.

[0031] The external vortex flows into the separation cylinder 1 from the external flow channel 24 until the large particles and medium particles are transported to the bottom of the separation cylinder 1, while the internal vortex generated from the bottom of the separation cylinder 1 inputs the medium particles and small particles into the internal flow channel 25, so that the impurities entering the internal flow channel 25 are circulated and sent into the storage box 3.

[0032] As another embodiment further provided by the present invention, a plurality of brackets 41 are fixedly installed between the double-pointed block 4 and the inner wall of the isolation tube 2 , and cavities 42 are formed between adjacent brackets 41 .

[0033] Specifically, the air flow enters the air inlet 11 at the upper end of the isolation tube 2 .

[0034] The bracket 41 provides the mounting connection and impact resistance of the double-pointed block 4. At the same time, the cavity 42 will eventually discharge the airflow out of the air outlet 12, and the airflow entering the air inlet 11 will form a closure on the upper end of the isolation tube 2, and part of the airflow will also enter the isolation tube 2, and form a downward impact on the airflow blowing up the cavity 42. The airflow at the end of the inner vortex is not easily disturbed by this part of the downward airflow, so that the downward airflow will remove the airflow that is finally discharged again, further reducing the impurity content in the discharged airflow, and the impacted impurity particles circulate on the upper end face of the double-pointed block 4, increasing the downward impact force, so that the impurity particles pass through the cavity 42 and fall into the storage box 3.

[0035] As another embodiment further provided by the present invention, a support base 23 for the storage box 3 to slide is fixedly mounted on the conveying sheet 21 , a through hole 231 is provided on the support base 23 , and an arrangement of holes 31 communicating with the through hole 231 is provided on the storage box 3 .

[0036] Specifically, a slider that slides on the support seat 23 is provided at the bottom of the storage box 3, and the slider is also equipped with a spring so that the storage box 3 can be reset after moving. The sliding connection method is a common existing technology and will not be described in detail here.

[0037] Furthermore, the end surface of the support seat 23 for the storage box 3 to slide is inclined toward the table-shaped side wall of the separation cylinder 1, so that the storage box 3 slides out of the isolation cylinder 2, and the drainage hole 31 is opened on one side of the bottom of the storage box 3, so that the drainage hole 31 is in a closed state in the default state, avoiding impurities from leaking and interfering with the internal vortex.

[0038] When the impurities in the storage box 3 increase, the center of gravity of the storage box 3 is changed, and the storage box 3 is deflected away from the axis direction (such as Figure 3 and Figure 4 As shown, Figure 4 This is from the perspective that the inverted conical inclined surface of the isolation tube 2 is in a vertical state), and at the same time, the upward airflow in the inner flow channel 25 prompts the storage box 3 to slide on the support seat 23, so that the opening of the storage box 3 is facing the direction of the external vortex flow, and at this time the row hole 31 is connected to the through hole 231, the purpose is to send the impurity particles stored in the storage box 3 into the through hole 231 and transport them downward. At the same time, the downward airflow in the outer flow channel 24 will also enter the storage box 3, and the airflow will assist the impurity particles to enter the through hole 231.

[0039] As another embodiment further provided by the present invention, a channel 211 communicating with the through hole 231 is provided on the conveying sheet 21 .

[0040] Specifically, the channel 211 runs through the entire conveying sheet 21 so as to convey the foreign particles downward.

[0041] The impurities collected in the storage box 3 are sent into the through hole 231 and then reset, and the impurities collected in the through hole 231 are transported downward into the channel 211. The vibration generated by the external vortex impacting the conveying sheet 21 can reduce the blockage problem of the channel 211, making it convenient to concentrate the collected impurities for discharge downward.

[0042] As another embodiment further provided by the present invention, a square tube 22 connected to the channel 211 is fixedly mounted on the separation cylinder 1 .

[0043] Specifically, the square tube 22 is fixedly connected to the lower end of the conveying sheet 21 , and the square tube 22 passes through the lower section of the separation cylinder 1 , so that the square tube 22 can directly convey impurities to the outside of the separation cylinder 1 .

[0044] The impurity particles transported therein are sent into the square tube 22 through the channel 211, and the square tube 22 discharges the impurities directly to the outside of the separation cylinder 1. On the one hand, it is convenient to collect the impurity particles collected separately, and on the other hand, it can avoid directly pouring the impurities into the bottom of the separation cylinder 1 and interfering with the generation of internal vortex.

[0045] Working principle: in the process of conveying impurities downward through the external vortex, it is guided by the side wall of the isolation cylinder 2, and the airflow begins to separate when it reaches the conveying piece 21, so that the impurities that pass through the gap of the conveying piece 21 and enter the internal vortex are not easy to return to the external vortex, thereby realizing the preliminary separation and processing of medium-sized particles, that is, the medium-sized particles in the external vortex can only be gathered and conveyed downward, while the medium-sized particles in the internal vortex can only be discharged upward, but before being discharged upward, they will contact the lower end surface of the double-pointed block 4, so that the medium-sized particles and small particles of impurities are intercepted and appear to be discharged upward. The circulating surge below forces these particles downward and into the storage box 3 for storage, thereby reducing the impurity content discharged from the air outlet 12. When the impurities in the storage box 3 increase, the center of gravity of the storage box 3 is changed, and the storage box 3 is deflected away from the axial direction. At the same time, the upward airflow in the inner flow channel 25 prompts the storage box 3 to slide on the support seat 23, so that the opening of the storage box 3 faces the direction of the external vortex flow, and at this time the discharge hole 31 is connected to the through hole 231, with the purpose of sending the impurity particles stored in the storage box 3 into the through hole 231 and transporting them downward until they are sent out of the separation cylinder 1.

[0046] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
