Description

Technical Field

[0001] This utility model relates to the field of gypsum dehydration technology, and in particular to a separation device for gypsum dehydration. Background Technology

[0002] A hydrocyclone is a common separation and classification device. When two phases of liquid to be separated enter the hydrocyclone tangentially from its periphery under a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the size difference between coarse and fine particles, they are subjected to different magnitudes of centrifugal force, centripetal buoyancy, and fluid drag. Under centrifugal sedimentation, most coarse particles are discharged through the underflow port of the hydrocyclone, while most fine particles are discharged through the overflow port, thus achieving the purpose of separation and classification. The density of the produced gypsum slurry varies. Some gypsum slurries contain more high-density gypsum slurry, while others contain more low-density gypsum slurry. When gypsum slurries of different densities enter the hydrocyclone for separation through the feed port, different flow velocities will occur. The low-density gypsum slurry (with higher water content) flows faster and can be separated normally, while the high-density gypsum slurry (with lower water content) flows slower and is difficult to separate from the liquid in one step, requiring multiple separation operations, which affects the overall construction progress. Utility Model Content

[0003] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a separation device for gypsum dehydration, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A separation device for gypsum dehydration includes a telescopic component and several cyclone tubes. The telescopic component includes a connecting assembly and several telescopic sleeves with decreasing diameters. The several telescopic sleeves are concentrically arranged, with the smaller diameter sleeve fitted inside the larger diameter sleeve, and the smaller diameter sleeve can slide inside the larger diameter sleeve. The telescopic sleeves are disposed inside the cyclone tubes. The connecting assembly is connected to the smallest diameter telescopic sleeve and drives it to slide.

[0005] Preferably, the connecting assembly includes a rope and a rotating shaft, the rope being wound around the rotating shaft, one end of the rope being connected to a telescopic sleeve, and the rotating shaft being rotatably disposed on the outside of the cyclone tube.

[0006] Preferably, the telescopic sleeve includes sleeve I, sleeve II, and sleeve III. Sleeve I is fixedly connected inside the cyclone tube. The diameter of sleeve I is larger than the diameter of sleeve II, and the diameter of sleeve II is larger than the diameter of sleeve III. Sleeve II is slidably connected inside sleeve I, and sleeve III is slidably connected inside sleeve II.

[0007] Preferably, the sleeve I has a plurality of recessed grooves I, and the sleeve II has a slider I on its outer side, the slider I being slidably disposed within the grooves I.

[0008] Preferably, the sleeve II has a plurality of recessed grooves II inside, and the sleeve III has a slider II on the outside, which is slidably disposed in the grooves II.

[0009] Preferably, a lifting ring is provided on sleeve III, and the rope passes through the cyclone separator and is connected to the lifting ring.

[0010] Preferably, the connecting assembly also includes a driver disposed outside the cyclone tube, and the driver is connected to the rotating shaft.

[0011] Preferably, the cyclone tube is provided with a feed inlet, an underflow outlet, and an overflow outlet. The feed inlet is located on the outside of the cyclone tube, the underflow outlet is located at the lower end of the cyclone tube, the overflow outlet is located at the upper end of the cyclone tube, and the telescopic sleeve is located at the overflow outlet.

[0012] This utility model has the following advantages and beneficial effects: In this invention, a telescopic sleeve is located inside a cyclone tube. When gypsum slurry enters the cyclone tube, the gypsum slurry squeezes the outside of the telescopic sleeve, accelerating the flow rate of the gypsum slurry within the cyclone tube. This allows for thorough separation of gypsum and liquid within the gypsum slurry. The telescopic sleeve employs a telescopic structure design. When the content of low-density gypsum slurry is high, the telescopic sleeve is tightened via a connecting component. The low-density gypsum slurry flows faster within the cyclone tube, enabling proper separation of gypsum and liquid. The separation device can adjust its structure according to the different densities of the produced gypsum slurry, resulting in different separation structures for gypsum slurries of different densities. This not only ensures effective separation but also accelerates the construction progress. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Example like Figures 1-2 As shown, a separation device for gypsum dewatering includes a telescopic component and a hydrocyclone 1. The hydrocyclone 1 is provided with an inlet 101, an underflow outlet 103, and an overflow outlet 102. The inlet 101 is located on the outside of the hydrocyclone 1, and the inlet 101 is tangentially positioned inside the hydrocyclone 1. Gypsum slurry is sprayed into the hydrocyclone 1 at high speed from the inlet 101. The underflow outlet 103 is located at the lower end of the hydrocyclone 1. Powdered gypsum is separated by the hydrocyclone 1 and falls from the underflow outlet 103. The overflow outlet 102 is located at the upper end of the hydrocyclone 1, and the liquid flows out from the overflow outlet 102. The telescopic component is annularly positioned at the overflow outlet 102.

[0019] like Figures 1-5 As shown, the telescopic component includes a connecting assembly 5 and several telescopic sleeves A. The telescopic sleeves A are arranged in a ring around the overflow port 102, and the diameter of the telescopic sleeves A decreases from top to bottom. The several telescopic sleeves A are arranged concentrically, and the telescopic sleeves are slidably connected in pairs. The telescopic sleeve A with a smaller diameter is sleeved inside the sleeve with a larger diameter, and the telescopic sleeve A with a smaller diameter can slide inside the telescopic sleeve A with a larger diameter. The telescopic sleeves A are set inside the vortex tube 1. The connecting assembly 5 is connected to the telescopic sleeve A with the smallest diameter (bottom side) and drives it to slide.

[0020] like Figures 1-5As shown, the telescopic sleeve A includes sleeve I2, sleeve II3, and sleeve III4. Each of sleeves I2, II3, and III4 is hollow. Sleeve I2 is fixedly connected inside the vortex tube 1, and sleeve I2 and overflow port 102 are concentrically arranged. The diameter of sleeve I2 is larger than the diameter of sleeve II3, and the diameter of sleeve II3 is larger than the diameter of sleeve III4. Sleeve II3 is slidably connected inside sleeve I2, and sleeve III4 is slidably connected inside sleeve II3. Several grooves I21 are recessed inside sleeve I2. 1. A slider I31 is provided on the inner wall of sleeve I2 and along the axial direction of sleeve I2. Slider I31 is slidably disposed in slide groove I21. Slide groove I21 restricts slider I31 to move only along the direction of slide groove I21, preventing sleeve II3 from rotating, so that sleeve II3 can slide stably along the axial direction of sleeve I2 within sleeve I2. Several slide grooves II32 are recessed inside sleeve II3 and are provided on the inner wall of sleeve II3 and along the axial direction of sleeve II3. A slider II41 is provided on the outer side of sleeve III4. Slider II41 is slidably disposed within slide groove II32. Slide groove II32 restricts slider II41 to move only along the direction of slide groove II32, preventing sleeve III4 from rotating. This allows sleeve III4 to slide stably along the axial direction of sleeve II3 within sleeve II3. Since the diameters of sleeve I2, sleeve II3, and sleeve III4 decrease sequentially, when slider I31 is at the lower end of slide groove I21 and slider II41 is at the lower end of slide groove II32, sleeve I2, sleeve II3, and sleeve III4... III4 has a conical structure, with the telescopic sleeve A inside the vortex tube 1, which reduces the internal volume of the vortex tube 1. When the gypsum slurry is introduced into the vortex tube 1, the gypsum slurry squeezes the outside of the telescopic sleeve A. When the gypsum slurry comes into contact with the telescopic sleeve A, it does not cause the telescopic sleeve A to shake. The telescopic sleeve A accelerates the flow speed of the gypsum slurry in the vortex tube 1, so that the gypsum and liquid in the gypsum slurry are fully separated. The separated liquid also flows directly out from the overflow port 102 through the middle of the telescopic sleeve A. This method can separate the gypsum and liquid to the greatest extent.

[0021] like Figures 1-5As shown, the connecting assembly 5 includes a driver 53, a rope 54, and a rotating shaft 51. The rope 54 is wound around the rotating shaft 51 and is made of a flexible material. One end of the rope 54 is connected to the telescopic sleeve A. The rotating shaft 51 is rotatably disposed on the outside of the cyclone tube 1 and is equipped with a support 52. The rotating shaft 51 is supported on the outside of the cyclone tube 1 by the support 52 and can rotate within the support 52. The driver 53 is disposed on the outside of the cyclone tube 1 and is connected to the rotating shaft 51. The driver 53 is a rotary motor, such as an AM8100 motor, or other structures, and its purpose is to drive the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, the rope 54 continuously loosens or tightens on the rotating shaft 51. A lifting ring 42 is provided on the sleeve 54, and the rope 54 passes through the cyclone tube and is connected to the lifting ring 42. When the rope 54 loosens on the rotating shaft 51, the sleeve 54, due to its own... The sleeve II 3 slides towards the lower end of the cyclone tube 1 due to its own weight. When the rope 54 is tightened on the rotating shaft 51, the sleeve III 4 is pulled by the rope 54 to slide towards the position of the sleeve I 2. The sleeve II 3 also slides towards the position of the sleeve I 2 synchronously with the sleeve II 3. The entire telescopic sleeve A is tightened as a whole. When the content of high-density gypsum slurry is relatively large, the telescopic sleeve A can be extended through the connecting component 5, so that the internal volume of the cyclone tube 1 is reduced, which is more conducive to the separation of gypsum and liquid. When the content of low-density gypsum slurry is relatively large, the telescopic sleeve A is tightened through the connecting component 5. The low-density gypsum slurry flows faster in the cyclone tube 1, and can be separated from gypsum and liquid normally. The separation device can adjust its structure according to the different densities of the produced gypsum slurry, so that gypsum slurry of different densities has different separation structures, which not only ensures the normal separation effect, but also speeds up the construction progress.

[0022] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
