Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a sodium sulfate cyclone. Background Technique

[0002] The sodium sulfate cyclone is a device that uses the principle of centrifugal sedimentation for separation. It is commonly used in the solid-liquid separation of mirabilite slurry after the sodium sulfate solution is frozen and crystallized in the zero-discharge sodium sulfate recovery section of printing and dyeing wastewater treatment. The working principle of the sodium sulfate cyclone is similar to that of the hydrocyclone. The sodium sulfate solution to be treated enters tangentially from the periphery of the cyclone at a certain pressure to generate a high-speed rotating flow field. In this rotating flow field, due to the different densities of sodium sulfate and other components, the centrifugal forces received are also different, thus achieving separation. As an efficient separation device, the sodium sulfate cyclone plays an important role in the chemical production process.

[0003] In the prior art, an overflow pipe and a sand settling port are provided inside the cyclone. Among them, the overflow pipe is used to convey substances with a smaller density in the fluid, and the sand settling port is used to convey substances with a larger density. Moreover, when the cyclone is in use, flow rate adjustment is a crucial link. The size of the flow rate directly affects the hydrodynamic characteristics inside the cyclone, and thus affects the separation efficiency.

[0004] However, the parameters of the conventional cyclone are generally fixed, resulting in the need for corresponding replacement when the staff adjusts the flow rate, so as to adjust the overflow amount. The operation is cumbersome, prone to errors, and reduces the processing efficiency. Summary of the Utility Model

Specific implementation manners

[0022] In order to clearly and completely describe the purpose, technical solutions of the utility model and make the advantages more clear, the following further details the embodiments of the utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the utility model, rather than all of the embodiments, and are only used to explain the embodiments of the utility model, not to limit the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the utility model.

[0023] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a sodium sulfate cyclone, comprising: a frame 1, a feed distributor 9 is fixedly installed at the top of the frame 1, an overflow box 3 is arranged at the top of the feed distributor 9, a plurality of evenly distributed overflow elbows 2 are fixedly installed on the outer periphery of the overflow box 3, the lower ends of the overflow elbows 2 are fixedly installed with cyclone bodies 6 respectively, a plurality of groups of flow regulating mechanisms 8, the flow regulating mechanisms 8 are all arranged at the lower part of the cyclone body 6, each group of flow regulating mechanisms 8 includes a mounting sleeve 802, the mounting sleeves 802 are respectively fixedly installed at the lower part of the cyclone body 6 on the same side, a plurality of evenly distributed limiting frames 801 are fixedly installed on the outer periphery of each mounting sleeve 802, a movable collar 803 is rotatably installed in the same group of limiting frames 801, a support frame 8011 is fixedly installed at the lower part inside each mounting sleeve 802, a plurality of evenly distributed partition plates 8010 are rotatably installed in the middle of the support frame 8011, one end of each partition plate 8010 away from the support frame 8011 is fixedly installed with a pin shaft 8012 and the pin shafts 8012 all penetrate through the mounting sleeve 802, limiting plates 804 are fixedly installed at the ends of the pin shafts 8012, guiding grooves 805 are formed in the middle of the limiting plates 804, guiding columns 806 are movably installed in the guiding grooves 805 and one ends of the guiding columns 806 in the same group close to the mounting sleeve 802 are fixedly installed on the outer periphery of the movable collar 803 in the same group. When the mixture enters the cyclone body 6 along the tangential direction under a certain pressure, a high-speed rotating liquid flow is formed in the cavity. Due to the action of centrifugal force, substances with a large density are thrown towards the wall of the device and move downward, and finally are discharged through the sand settling port. At the same time, substances with a small density are pushed towards the central axis and form an upward inner vortex, and finally are discharged through the overflow pipe. When discharging through the sand settling port, at this time, the driving mechanism can drive the movable collar 803 to rotate in the limiting frame 801. Since there are clamping blocks and clamping grooves between the limiting frame 801 and the movable collar 803, it can ensure that the movable collar 803 will not fall off the limiting frame 801 when rotating. Furthermore, the guiding column 806 cooperates with the guiding groove 805 on the limiting plate 804 to drive the pin shaft 8012 to rotate, and then the partition plate 8010 in the mounting sleeve 802 will rotate synchronously. According to the rotation degree of the movable collar 803, the staff can control the opening degree of the partition plate 8010, thereby improving the classification efficiency, controlling the phenomenon of overflow running coarse, reducing the amount of fine particles in the underflow, and being beneficial to improving the working efficiency of the cyclone body 6. Here, the model of the cyclone body 6 can adopt the FX100-PU-B model.

[0024] A underflow box 7 is fixedly installed at the lower part of the frame 1, and the lower parts of the cyclone bodies 6 are all arranged inside the upper part of the underflow box 7. The upper parts of the outer peripheries of the cyclone bodies 6 are all cylindrical, and overflow pipes are arranged inside the upper parts of the cyclone bodies 6. The lower parts of the outer peripheries of the cyclone bodies 6 are all arranged in a conical shape, and sand settling ports are arranged inside the lower parts of the cyclone bodies 6. Feed pipes 4 are fixedly installed on the upper parts of the outer peripheries of the cyclone bodies 6. The upper ends of the feed pipes 4 are respectively butted against a feed distributor 9. Stainless steel pipe clamp valves 5 are flange-connected to the outer peripheries of the feed pipes 4. By providing the stainless steel pipe clamp valves 5, since the stainless steel pipe clamp valve 5 is a special type of valve mainly used for controlling and regulating the fluid transportation containing solid or semi-solid particles, it is convenient for the staff to control the fluid transportation.

[0025] A driving mechanism is respectively arranged on the mounting sleeve 802. The driving mechanism is used to drive the movable collar 803 to rotate. The driving mechanism includes a gear ring 808 which is fixedly installed at the top end of the movable collar 803. The driving mechanism further includes a stepping motor 807 which is respectively fixedly installed at the middle upper part of the outer periphery of the same-side mounting sleeve 802. Driving ends of the stepping motors 807 are all fixedly installed with gears 809 which are respectively meshed with the gear ring 808 on the same side. By controlling the stepping motor 807, at this time, the stepping motor 807 can drive the gear 809 to rotate. Since the gear 809 is meshed with the gear ring 808, the gear ring 808 will drive the movable collar 803 to rotate inside the limit frame 801. Cooperating with the guide posts 806 and the guide grooves 805, the opening degree of the partition plate 8010 can be driven, and the automation degree is relatively high and the operation is simple.

[0026] During the actual use process, after the staff complete the connection of the relevant pipelines on the equipment, at this time, the feed pipe 4 will input fluid into the cyclone body 6. Under the action of centrifugal force, substances with large density are discharged through the sand settling port, and substances with small density are discharged through the overflow pipe. When the sand settling port discharges outward, the stepping motor 807 cooperates with the gear 809 and the gear ring 808 to drive the movable collar 803 to rotate inside the limit frame 801. Then the limit plate 804 cooperates with the guide posts 806 and the guide grooves 805 to drive the pin shaft 8012 and the partition plate 8010 to rotate. Then the partition plate 8010 can achieve different opening positions, so that the gap size at the sand settling port can be flexibly adjusted, the separation efficiency can be improved, and the stable operation of the equipment can be ensured.

[0027] Although the above describes the illustrative specific embodiments of the present application for the convenience of those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all the application creations using the concept of the present application are within the scope of protection.
