Description

Technical Field

[0001] This utility model relates to the field of cyclone separator technology, and more specifically, to a sodium sulfonate cyclone separator device. Background Technology

[0002] When using a cyclone separator to treat gas containing sodium sulfonate powder, the airflow of sodium sulfonate powder enters the cylinder of the cyclone separator tangentially and rotates spirally downward along the inner wall of the cylinder. The dust collides with the inner wall under the action of centrifugal force and falls into the storage tank under the action of gravity. The separated gas is discharged from the outlet pipe.

[0003] Utility Model Patent Application No. CN202323596288.7 discloses a cyclone separator for improving the yield of sodium α-alkenyl sulfonate. The device includes a cyclone separator with a dust removal mechanism connected to the top of its outlet pipe. The dust removal mechanism comprises a connecting pipe, a contraction pipe, a transition pipe, a diffuser pipe, and an outlet pipe connected in sequence. The inner diameter of the contraction pipe gradually decreases at the end furthest from the connecting pipe, while the inner diameter of the diffuser gradually increases at the end furthest from the transition pipe. When this invention is used, when the airflow containing sodium α-alkenyl sulfonate powder passes through the contraction pipe, the flow velocity naturally increases due to the narrowing of its inner diameter, and the static pressure decreases. The sodium α-alkenyl sulfonate powder particles in the airflow are propelled into the transition pipe, where they accelerate and rotate before striking its inner wall. As the velocity decreases and the pressure increases within the pipe, the sodium α-alkenyl sulfonate powder falls. At the outlet of the diffuser pipe, the reduced flow velocity further increases the settling rate of the sodium α-alkenyl sulfonate powder, ultimately leading to its collection and achieving the goal of improving the yield of sodium α-alkenyl sulfonate powder.

[0004] The aforementioned patent describes a method where, when a converging tube of a dust removal mechanism is connected to the outlet pipe of a cyclone separator, its narrower inner diameter causes the sodium sulfonate powder to accelerate and rotate within the transition tube before striking its inner wall. As the speed decreases and the pressure increases within the pipe, the sodium sulfonate powder falls, increasing the yield of the sodium sulfonate powder. The falling sodium sulfonate powder enters the cyclone separator through the converging tube. Because an upward airflow is formed inside the converging tube in the opposite direction to the falling material, this counter-current airflow acts as an invisible barrier, continuously interacting with the falling sodium sulfonate powder. Some sodium sulfonate powder cannot overcome the airflow resistance, resulting in suspension and backflow, causing a large amount of material to fail to enter the cyclone separator for effective collection, ultimately significantly reducing the overall collection efficiency.

[0005] Therefore, we have made improvements to this and proposed a sodium sulfonate cyclone separator. Utility Model Content

[0006] The purpose of this invention is as follows: The falling sodium sulfonate powder enters the cyclone separator through the contraction tube. Because an upward airflow is formed inside the contraction tube in the opposite direction to the falling material, this reverse-flowing air acts like an invisible barrier, continuously interacting with the falling sodium sulfonate powder. Some sodium sulfonate powder cannot overcome the airflow resistance and exhibits phenomena such as suspension and backflow, resulting in a large amount of material failing to enter the cyclone separator smoothly for effective collection, ultimately greatly reducing the overall collection efficiency.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A sodium sulfonate cyclone separator includes a base frame, on which a cyclone separator cylinder is fixedly mounted. The cyclone separator cylinder comprises a cylindrical body and a conical body, with the cylindrical body located above the conical body. A feed pipe is fixedly mounted tangentially to the cylindrical body, an outlet pipe is fixedly mounted at the top center of the cylindrical body, and a discharge pipe is fixedly mounted at the bottom of the conical body. The feed pipe, outlet pipe, and discharge pipe are all connected to the inner cavity of the cyclone separator cylinder. A separation component is fixedly mounted above the outlet pipe.

[0009] Furthermore, the separation assembly includes a separation tube installed on and connected to the top of the outlet pipe, and an airflow riser pipe located on the same central axis as the separation tube is provided inside the separation tube. A connecting block is fixedly installed between the outer wall of the airflow riser pipe and the inner wall of the separation tube.

[0010] Furthermore, a feeding chamber is formed between the outer wall of the airflow riser and the inner wall of the separation pipe and the outlet pipe. A contraction pipe is installed above the airflow riser, a transition pipe is installed above the contraction pipe, and a diffuser is installed above the transition pipe.

[0011] Furthermore, the inner diameter of the end of the contraction tube away from the airflow riser tube gradually decreases, while the inner diameter of the end of the diffuser tube away from the contraction tube gradually increases, and the transition tube is installed at the connection point between the diffuser tube and the contraction tube.

[0012] Furthermore, the outer wall of the transition tube is equipped with an annular block, and an annular impeller is rotatably fitted on the outer periphery of the annular block. An annular groove is formed on the inner circumference of the annular impeller to rotatably fit the annular block.

[0013] Furthermore, mounting slots are provided on both sides above the annular impeller, and uprights are installed in the two mounting slots, with fixing strips installed at the top of the two uprights.

[0014] Furthermore, fixing blocks are installed on both sides of the bottom of the fixing strip, and the two fixing blocks are rotatably fitted with rollers that fit against the inner wall of the diffuser tube. The outer diameter of the diffuser tube is smaller than the inner diameter of the separation tube and there is a gap between them. The rollers have outward spiral grooves on their circumference. The bottom of the fixing strip is equipped with a drive rod that is located on the same central axis as the airflow riser tube.

[0015] Furthermore, the bottom of the airflow riser is equipped with a diffuser block located at the bottom opening of the outlet pipe, the periphery of the drive rod is equipped with fan blades located inside the airflow riser, and the bottom end of the drive rod is equipped with a cleaning frame located inside the cyclone separator cylinder, the cleaning frame being in contact with the inner wall of the cyclone separator cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model utilizes the dual action of the cyclone separator cylinder and the separation components, employing principles such as centrifugal force and pressure difference, to achieve efficient separation of sodium sulfonate powder and airflow. Addressing the issue of upward airflow obstructing the descent of sodium sulfonate powder within the contraction tube, the device uses components such as a transition tube, diffuser tube, and annular impeller to guide the separated sodium sulfonate powder back into the cyclone separator cylinder, effectively reducing material suspension and backflow, and ensuring a smooth collection process.

[0018] 2. This utility model automatically cleans the inner wall of the cyclone separator cylinder using a cleaning frame, avoiding material residue that could affect the separation effect; the conveying structure composed of rollers and annular impeller automatically transports the separated sodium sulfonate powder back to the feeding chamber, reducing manual intervention and improving the degree of automation and work efficiency. The layout of each component of the device is reasonable, and the drive rod, fan blades, rollers, annular impeller and other components are interconnected, achieving efficient separation and conveying while reducing the use of additional power equipment, thus reducing energy consumption and equipment costs.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Please refer to Figure 1-7 A sodium sulfonate cyclone separator includes a base frame 1. A cyclone separator cylinder 2 is fixedly installed on the top of the base frame 1. The cyclone separator cylinder 2 is composed of a cylindrical body 21 and a conical body 22. The cylindrical body 21 is located above the conical body 22. A feed pipe 3 is fixedly installed tangentially to the cylindrical body 21. An outlet pipe 4 is fixedly installed at the top center of the cylindrical body 21. A discharge pipe 5 is fixedly installed at the bottom of the conical body 22. The feed pipe 3, the outlet pipe 4, and the discharge pipe 5 are all connected to the inner cavity of the cyclone separator cylinder 2. A separation component 7 is fixedly installed above the outlet pipe 4.

[0030] Specifically, the airflow containing sodium sulfonate powder enters the cyclone separator cylinder 2 tangentially along the feed pipe 3. Under centrifugal force, most of the sodium sulfonate powder is thrown against the inner wall of the cylinder 21, slides down the cone 22, and is finally discharged from the discharge pipe 5; a small amount of airflow containing sodium sulfonate powder enters the separation component 7 from the outlet pipe 4 at the top center of the cylinder 21.

[0031] Please refer to Figure 2-4The separation assembly 7 includes a separation pipe 701 installed on top of and connected to the outlet pipe 4. An airflow riser pipe 702, coaxial with the separation pipe 701, is disposed inside the separation pipe 701. A connecting block 704 is fixedly installed between the outer wall of the airflow riser pipe 702 and the inner wall of the separation pipe 701. A discharge chamber 705 is formed between the outer wall of the airflow riser pipe 702 and the inner walls of the separation pipe 701 and the outlet pipe 4. A contraction pipe 706 is installed above the airflow riser pipe 702. A transition pipe 719 is installed above the contraction pipe 706. A diffuser pipe 707 is installed above the transition pipe 719. The inner diameter of the constriction tube 706 gradually decreases at the end furthest from the airflow riser tube 702, while the inner diameter of the diffuser tube 707 gradually increases at the end furthest from the constriction tube 706. The transition tube 719 is installed at the connection between the diffuser tube 707 and the constriction tube 706. In use, when the airflow of sodium sulfonate powder passes through the constriction tube 706, the flow velocity naturally increases and the static pressure decreases due to the narrowing of its inner diameter. The sodium sulfonate powder particles in the airflow are pushed into the transition tube 719. When the airflow passes through the transition tube 719 and enters the diffuser tube 707, the sodium sulfonate powder falls onto the inner wall of the diffuser tube 707 as the velocity in the pipe decreases and the pressure increases.

[0032] Specifically, after the airflow containing sodium sulfonate powder enters the separation component 7, it first passes through the contraction tube 706. As the inner diameter of the contraction tube 706 gradually decreases at the end furthest from the airflow riser tube 702, the airflow velocity increases and the static pressure decreases. Under the pressure difference and the push of the airflow, the sodium sulfonate powder particles separate from the airflow and enter the transition tube 719. Subsequently, the airflow enters the diffuser tube 707 through the transition tube 719. Since the inner diameter of the diffuser tube 707 gradually increases at the end furthest from the contraction tube 706, the airflow velocity slows down and the pressure increases, causing more sodium sulfonate powder to fall onto the inner wall of the diffuser tube 707 under gravity.

[0033] Please refer to Figure 5-7The outer wall of the transition tube 719 is equipped with an annular block 708. An annular impeller 709 is rotatably fitted on the outer periphery of the annular block 708. An annular groove 711 is formed on the inner circumference of the annular impeller 709 to rotatably engage with the annular block 708. Mounting grooves 713 are formed on both sides of the upper part of the annular impeller 709. A vertical rod 712 is installed in the two mounting grooves 713. A fixing strip 710 is installed at the top of the two vertical rods 712. Fixing blocks 714 are installed on both sides of the bottom of the fixing strip 710. A roller body 715 is rotatably fitted on both sides of the fixing blocks 714 to fit against the inner wall of the diffuser tube 707. The outer diameter of the diffuser tube 707 is smaller than the inner diameter of the separation tube 701, and there is a gap between them. The circumference of the roller body 715 is formed with an outward spiral groove 716. The bottom of the fixing strip 710 is equipped with a part that is co-centered with the airflow riser tube 702. The drive rod 703 of the shaft; when the drive rod 703 rotates, it can drive the fixing bar 710 to rotate, so that the two rollers 715 that are in contact with the inner wall of the diffuser tube 707 rotate on its surface. The sodium sulfonate powder scattered on the inner wall of the diffuser tube 707 is conveyed upward through the rollers 715 and the spiral grooves 716 on their surface to the gap left between the diffuser tube 707 and the separation tube 701. The fixing bar 710 drives the annular impeller 709 to rotate through the two uprights 712, thereby conveying the sodium sulfonate powder downward into the feeding chamber 705 and falling downward. The bottom of the airflow riser tube 702 is equipped with a diffuser block 717 located at the bottom opening of the outlet tube 4. The periphery of the drive rod 703 is equipped with a fan blade 718 located in the airflow riser tube 702. The bottom end of the drive rod 703 is equipped with a cleaning frame 6 located in the cyclone separator cylinder 2. The cleaning frame 6 is in contact with the inner wall of the cyclone separator cylinder 2.

[0034] Specifically, the annular impeller 709 on the outer wall of the transition tube 719 and its related components work together. When the drive rod 703 rotates, it drives the fixing bar 710 to rotate, causing the roller 715, which is in contact with the inner wall of the diffuser tube 707, to rotate. The spiral groove 716 on the periphery of the roller 715 conveys the sodium sulfonate powder scattered on the inner wall of the diffuser tube 707 upward to the gap between the diffuser tube 707 and the separation tube 701. At the same time, the fixing bar 710 drives the annular impeller 709 to rotate through the two uprights 712, conveying the sodium sulfonate powder in the gap downward to the feeding chamber 705, so that it falls into the cyclone along the feeding chamber 705. The cleaning frame 6 at the bottom of the drive rod 703 of the separator cylinder 2 is attached to the inner wall of the cyclone separator cylinder 2, which can clean the inner wall of the cylinder and prevent material residue. The fan blades 718 located on the periphery of the drive rod 703 inside the airflow riser pipe 702 rotate under the action of airflow, providing power for the operation of the roller 715 and the annular impeller 709, while promoting airflow. The diffuser block 717 at the bottom of the airflow riser pipe 702 is located at the bottom opening of the outlet pipe 4, which helps to guide the airflow smoothly into the separation component 7.
