Description

Technical Field

[0001] The invention relates to the technical field of separation equipment, in particular to a cyclone separator which is easy to maintain. Background Art

[0002] The cyclone separator is a highly efficient gas-solid separation device based on the principle of centrifugal sedimentation. Its core working process is as follows: the dust-laden gas flow enters the cylinder through the tangential inlet to form a high-speed rotating flow field. The solid particles are thrown to the cylinder wall under the action of centrifugal force and move downward along a spiral trajectory to the dust collecting chamber for collection. The purified gas is discharged through the central riser. Although this technology has advantages such as simple structure and stable operation, in actual industrial scenarios, the problem of cylinder wear always restricts the long-term operation of the equipment.

[0003] Current technological improvements are mostly focused on improving material wear resistance or optimizing flow field distribution, such as using high-chromium cast iron linings to enhance the hardness of the cylinder wall, or adding guide vanes at the inlet section to improve the airflow pattern. However, such solutions can only slow down the wear rate to a limited extent, and cannot change the mechanism of continuous friction of the particle flow on the same area along a fixed spiral path in a static cylinder. Especially when processing high-hardness particles such as quartz sand and catalyst powder, the cylinder will still experience local deep wear within hundreds of hours, causing the company to frequently shut down for maintenance, seriously affecting production continuity.

[0004] More importantly, the static cylinder structure makes the spiral motion trajectory of the particle group relatively fixed. This friction effect will form spiral groove wear on the inner wall of the cylinder consistent with the particle trajectory. When the spiral groove is deep, the cylinder needs to be replaced, which is relatively wasteful.

[0005] In addition, the current cyclone separators will have a discharge valve installed at the bottom of the cylinder for discharge, and the discharge valve needs to be connected to a motor drive. Summary of the invention

[0006] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a cyclone separator that is easy to maintain, so as to solve the problem of the existing cyclone separator proposed in the above-mentioned background technology that the static cylinder structure causes the particle flow to form deep groove wear along the fixed spiral trajectory, forcing the cylinder to be frequently replaced and requiring a motor-driven discharge valve to be configured, resulting in the dual technical defects of waste of resources and surge in maintenance costs.

[0029] It should be noted that the discharge valve component group 03 is mainly used to discharge solid particles in actual use.

[0033] It should be noted that the main driving component group 04 mainly relies on the airflow entering from the outer shell 41 to blow the impeller 42, and drives the rotation of the lower cylinder component group 02 through the rotational force of the impeller 42 in conjunction with the upper connecting structure. By being able to drive the lower ring frame 32 in the discharge valve component group 03 to rotate, the use of a motor is avoided and the cost of use is reduced.

[0034] In an optional embodiment: an air inlet and an air outlet are respectively provided on both sides of the outer inlet shell 41, the air inlet of the outer inlet shell 41 is used to connect to an external air inlet duct, and the air outlet of the outer inlet shell 41 is used to connect to the side air inlet nozzle 12 on the upper cylinder shell 11, the axial position of the impeller member 42 is fixedly connected with a rotating shaft, and the rotating shaft is connected to the outer inlet shell 41 through a bearing, the side rod member 43 is fixedly connected to one end of the rotating shaft of the impeller member 42, the upper positioning frame 410 is fixedly connected to the outer inlet shell 41, the upper positioning frame 410 is connected to the shifting transmission rod 44 through a bearing, the transmission gear member 411 meshes with the gear ring member 17, and one end of the lower transmission rod 49 is fixedly connected to the rotating shaft on the inner valve impeller 34.

[0035] In an optional embodiment: the support frame component group 05 includes a main bracket 51, a side mounting frame 52, a Z-shaped mounting frame 53 and an L-shaped mounting frame 54, the main bracket 51 is supported on the ground, the top of the main bracket 51 contacts the outer shell 41, the main bracket 51 is connected to the planetary gear reducer 47 through the side mounting frame 52, the Z-shaped mounting frame 53 and the main bracket 51 are fixedly connected, the Z-shaped mounting frame 53 is connected to the lower transmission rod 1 48 and the lower transmission rod 2 49 through a bearing, three L-shaped mounting frames 54 are provided, and the three L-shaped mounting frames 54 are connected between the main bracket 51 and the upper cylinder outer shell 11.

[0036] Working principle: The air that needs to be separated from the solid and gas outside will first flow into the outer shell 41 through the external air pipe, and the air flow will flow from the left side to the right side of the outer shell 41 ( Figure 3As shown in the figure, when the airflow flows, it will drive the impeller 42 in the outer shell 41 to rotate. The rotation of the impeller 42 will drive the planetary gear reducer 45 to work through the side rod 43 and the transposition transmission rod 44. The planetary gear reducer 45 will reduce the speed of the rotation force and then drive the transmission gear 411 and the vertical transmission rod 46 to rotate. The transmission gear 411 rotating at a low speed drives the gear ring 17 to rotate, and then drives the lower cylinder 21, the chassis ring 22 and the bolt 23 to rotate at a low speed. The lower cylinder 21 rotating at a low speed can make the solid particles spirally descending inside rub evenly on the inner wall. Since the rotation speed of the lower cylinder 21 is very low, the flow trajectory of the internal spiral airflow is greatly affected, and the gas-solid separation will not be affected. When the airflow flows into the upper cylinder component group 01, it will contact the inner wall of the grinding ring 14. At this time, the spiral track of gas and solid will be initially formed on the inner wall of the grinding ring 14. After being rubbed for a long time, the grinding ring 14 can be quickly replaced by removing the bolt part 15, and the maintenance efficiency is high. The solid particles will spirally move downward into the lower cylinder body 21 rotating at a low speed, and finally flow into the discharge valve component group 03 through the bottom of the lower cylinder body 21; The rotating vertical transmission rod 46 will input the rotational force into the planetary gear reducer 47, and the planetary gear reducer 47 will increase the speed of the rotational force and transmit it to the lower transmission rod 1 48. The lower transmission rod 1 48 will drive the inner valve impeller 34 in the valve housing 33 to rotate through the lower transmission rod 2 49, thereby completing the discharge of solid particles. The solid particles will fall from the bottom of the valve housing 33 into the dust collecting bin connected below for collection, and the separated gas will spirally rise in the lower cylinder component group 02 and finally be discharged into the exhaust duct through the air outlet pipe 13, and the gas-solid separation will be completed at this time.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
