Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a plaster mortar hydrocyclone. Background Technology

[0002] Gypsum hydrocyclones are mainly used for the pre-concentration of desulfurization products in wet desulfurization processes such as limestone / gypsum method, ammonia method, and dual alkali method, so as to facilitate further dehydration by equipment such as vacuum belt conveyors and centrifuges. Therefore, gypsum hydrocyclones are put into operation in the gypsum dehydration system in flue gas desulfurization systems.

[0003] Due to continuous technological advancements, the concentration efficiency of gypsum hydrocyclones is constantly improving. The concentration of gypsum slurry in the underflow from gypsum hydrocyclones often exceeds 50%, even reaching 70% to 85%. This high concentration of gypsum slurry not only easily deposits and clogs pipes, but also causes cracking of the gypsum filter cake and difficulties in dewatering when it reaches the downstream vacuum belt dewatering machine. Since gypsum hydrocyclones are non-adjustable devices, existing patents provide a hydrocyclone (CN101786051A) that can dilute high-concentration gypsum slurry. It consists of an overflow tank, a collection tank, and a hydrocyclone. The collection tank is located at the lower end of the overflow tank, and the hydrocyclone is connected to the overflow tank. An overflow outlet pipe is also provided on the overflow tank, with its lower end located inside the collection tank. A valve is installed on the overflow outlet pipe.

[0004] However, the above technical solution relies solely on the overflow outlet pipe to introduce low-concentration slurry into the collection tank, which has a limited diffusion range and mixing degree. This results in inconsistent dilution of high-concentration slurry at different locations in the collection tank, affecting the quality of the final gypsum slurry. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plaster mortar hydrocyclone.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gypsum mortar hydrocyclone, comprising a hydrocyclone body, an overflow pipe located at the top of the hydrocyclone, an inlet pipe located at the upper part of the hydrocyclone body, and an underflow pipe installed at the lower end of the hydrocyclone body. The hydrocyclone body is composed of multiple connecting sections, and the hydrocyclone body is arranged in a spiral shape that gradually converges from top to bottom. The cross-sectional area of ​​the inlet opening of the hydrocyclone is consistent with the overall length of the hydrocyclone, and a turbulence-breaking device is surrounded at the connecting inner wall of the connecting sections.

[0007] Furthermore, the bottom of the overflow pipe extends into the body of the hydrocyclone and is below the horizontal height of the outlet end of the feed pipe.

[0008] As a preferred embodiment of this application, the turbulence breaker is a toothed structure arranged around the inner wall of the connecting body.

[0009] As a preferred embodiment of this application, the cross-sectional area of ​​the opening of the feed pipe is ≥2-4 times the cross-sectional area of ​​the outlet end of the feed pipe, and the feed pipe is arranged in a gradually converging shape.

[0010] As a preferred embodiment of this application, the overflow pipe, the cyclone body, and the underflow pipe are coaxially distributed.

[0011] As a preferred embodiment of this application, a fixing plate is provided on the outer end face of the hydrocyclone body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Adaptable to different working conditions and material characteristics: The hydrocyclone body is composed of multiple connecting sections in a gradually converging spiral shape. This structure can be flexibly adjusted according to the actual working conditions and material characteristics of plaster mortar. The connecting sections of different sections can be optimized for parameters such as particle size and concentration of the material, so that the hydrocyclone can maintain good separation performance under different working conditions.

[0014] Enhanced fluid rotation effect: The spiral design guides the plaster mortar entering the hydrocyclone to form a more stable and intense rotating flow field. When the fluid rotates within the spiral channel, the centrifugal force is more pronounced, which is beneficial for the effective separation of particles of different sizes and densities in the flow field, thus improving separation efficiency.

[0015] Inlet design matching overall length

[0016] To ensure stable fluid entry: the cross-sectional area of ​​the feed inlet is consistent with the overall length of the hydrocyclone. This design ensures that plaster mortar enters the hydrocyclone at a relatively stable speed and in a stable state. It avoids turbulence and jetting phenomena caused by improper feed inlet dimensions, ensuring the stability of the internal flow field of the hydrocyclone and thus improving the separation effect.

[0017] Optimized flow field distribution: A reasonable match between the feed inlet size and the hydrocyclone length helps to form a uniform flow field distribution inside the hydrocyclone. This allows the material to be fully subjected to centrifugal force within the hydrocyclone, providing sufficient time and space for particles of different sizes and densities to separate, thus improving separation accuracy and efficiency.

[0023] 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.

[0024] like Figure 1-3 As shown, this application provides a hydrocyclone for plaster mortar, comprising a hydrocyclone body 1, an overflow pipe 2 located at the top of the hydrocyclone, a feed pipe 3 located at the upper part of the hydrocyclone body 1, and an underflow pipe 4 installed at the lower end of the hydrocyclone body 1. The hydrocyclone body 1 is composed of multiple connecting sections 11, and the hydrocyclone body 1 is arranged in a gradually converging spiral shape from top to bottom. The cross-sectional area of ​​the feed inlet of the hydrocyclone is consistent with the overall length of the hydrocyclone, and a turbulence-breaking device 5 is arranged around the inner wall of the connecting sections 11. By assembling the hydrocyclone body 1 into multiple connecting sections 11 and arranging it in a gradually converging spiral shape, the material can form a more complex swirling path within the hydrocyclone, increasing the collision and shearing effects between materials, thereby improving separation efficiency. At the same time, the fact that the cross-sectional area of ​​the feed inlet of the hydrocyclone is consistent with the overall length, and the inclusion of the turbulence-breaking device 5, can effectively prevent material blockage during the feeding process, further improving the operational stability and reliability of the hydrocyclone.

[0025] Function: To achieve efficient separation of materials, prevent material blockage, and ensure the normal operation of the hydrocyclone.

[0026] Implementation principle: The spiral arrangement of the multi-segment connector 11 causes the material to swirl within the hydrocyclone, enhancing the collision and shearing effects between materials, thereby achieving separation. The design of the feed inlet opening cross-sectional area being consistent with the overall length ensures that the material is evenly distributed upon entering the hydrocyclone, preventing localized material concentration and blockage. The turbulence-breaking device 5 further breaks down and disperses the material through its toothed structure, further preventing blockage and improving the separation effect.

[0027] Product characteristics and performance parameters: The length of the hydrocyclone body 1 can be adjusted according to actual needs, generally between 1 and 3 meters; the cross-sectional area of ​​the hydrocyclone's inlet opening is consistent with the overall length. For example, when the cross-sectional area of ​​the inlet opening is 100 square centimeters, the overall length of the hydrocyclone is 1 meter; the separation efficiency of the hydrocyclone can reach 80% to 95%, and the processing capacity varies depending on the size of the hydrocyclone and the properties of the material, generally between 1 and 5 cubic meters per hour.

[0028] The bottom of the overflow pipe 2 extends into the hydrocyclone body 1 and is lower than the horizontal height of the outlet end of the feed pipe 3. This allows the material to form a more stable swirling flow in the hydrocyclone, further improving the separation efficiency. It also helps to reduce the material residue in the overflow pipe 2 and improve the material recycling rate.

[0029] Function: To improve separation efficiency and reduce material residue.

[0030] Operating principle: The bottom of the overflow pipe 2 is lower than the horizontal level of the outlet end of the feed pipe 3, causing the material to generate a downward swirling motion within the hydrocyclone. Fine particles in the material are more thoroughly separated and discharged from the overflow pipe 2, while coarser particles continue to move within the hydrocyclone and are eventually discharged from the underflow pipe 4, thus achieving efficient material separation. Simultaneously, this design also helps reduce material residue in the overflow pipe 2, improving the material recycling rate.

[0031] Product characteristics and performance parameters: The difference in horizontal height between the bottom of the overflow pipe 2 and the outlet end of the feed pipe 3 is generally between 10 and 30 cm. The specific value can be adjusted according to the size of the hydrocyclone and the properties of the material. The diameter of the overflow pipe 2 is generally 1 / 3 to 1 / 2 of the diameter of the hydrocyclone body 1. For example, when the diameter of the hydrocyclone body 1 is 30 cm, the diameter of the overflow pipe 2 can be 10 to 15 cm.

[0032] The turbulence breaker 5 is a toothed structure arranged around the inner wall of the connecting body 11. The turbulence breaker 5 adopts a toothed structure arranged around the inner wall of the connecting body 11, which can more effectively break and disperse materials, further improve the separation effect of materials, and at the same time better prevent material blockage and improve the operating stability of the hydrocyclone.

[0033] Function: To improve material separation efficiency and prevent material blockage.

[0034] Operating principle: The toothed turbulence-breaking device 5 generates strong shearing and impact forces on the material as it passes through the hydrocyclone, breaking down and dispersing agglomerated particles and thus improving the separation effect. Simultaneously, the toothed structure increases the friction between the material and the inner wall of the hydrocyclone, preventing material adhesion and blockage, and ensuring the normal operation of the hydrocyclone.

[0035] Product characteristics and performance parameters: The tooth height of the turbulence crusher 5 is generally 5-10 mm, and the spacing is 10-20 mm. The specific dimensions can be adjusted according to the particle size and properties of the material. The material of the turbulence crusher 5 is generally wear-resistant material, such as high manganese steel or hard alloy, to ensure its service life.

[0036] The cross-sectional area of ​​the opening of the feed pipe 3 is ≥2-4 times the cross-sectional area of ​​the outlet end of the feed pipe 3. The feed pipe 3 is arranged in a gradually narrowing shape. The cross-sectional area of ​​the opening of the feed pipe 3 is ≥2-4 times the cross-sectional area of ​​the outlet end, and the gradually narrowing shape can make the material flow accelerated when entering the hydrocyclone, further improving the separation effect of the material. At the same time, it also helps to reduce the material residue in the feed pipe 3 and improve the utilization rate of the material.

[0037] Function: To improve material separation efficiency and reduce material residue.

[0038] Implementation principle: The large cross-sectional area of ​​the feed pipe 3 allows for uniform distribution of material upon entry. As the feed pipe 3 gradually narrows, the material velocity gradually increases, resulting in accelerated flow upon entering the hydrocyclone. This accelerated flow enables stronger swirling motion within the hydrocyclone, further improving the separation effect. Simultaneously, the gradually narrowing feed pipe 3 design helps reduce material residue within it, increasing material utilization.

[0039] Product characteristics and performance parameters: The ratio of the cross-sectional area of ​​the opening of the feed pipe 3 to the cross-sectional area of ​​the outlet end is generally 2-4. For example, when the cross-sectional area of ​​the outlet end of the feed pipe 3 is 25 square centimeters, the cross-sectional area of ​​the opening can be 50-100 square centimeters. The length of the feed pipe 3 is generally 1 / 4-1 / 3 of the length of the hydrocyclone body 1. For example, when the length of the hydrocyclone body 1 is 2 meters, the length of the feed pipe 3 can be 0.5-0.67 meters.

[0040] The overflow pipe 2, the hydrocyclone body 1, and the underflow pipe 4 are coaxially distributed, which enables the material to form a more uniform and stable swirling flow in the hydrocyclone, further improving the separation efficiency. At the same time, it also helps to reduce turbulence and eddy currents in the material in the hydrocyclone, reduce energy loss, and improve the operating efficiency of the hydrocyclone.

[0041] Function: To improve separation efficiency and reduce energy loss.

[0042] Implementation principle: The coaxial distribution design allows the material to generate stable swirling motion along the axial direction within the hydrocyclone, reducing turbulence and eddies, thereby improving separation efficiency. Simultaneously, this design also helps reduce energy loss and improve the hydrocyclone's operating efficiency.

[0043] Product characteristics and performance parameters: The coaxiality of the overflow pipe 2, the hydrocyclone body 1 and the underflow pipe 4 is generally controlled between 0.1 and 0.5 mm to ensure stable flow of materials in the hydrocyclone; the operating power of the hydrocyclone is generally 1-5 kW, and the specific value can be adjusted according to the size of the hydrocyclone and the properties of the material.

[0044] A fixing plate 6 is provided on the outer end face of the hydrocyclone body 1. The fixing plate 6 on the outer end face of the hydrocyclone body 1 can facilitate the installation and fixing of the hydrocyclone, improve the stability of the hydrocyclone, and also help reduce the vibration generated by the hydrocyclone during operation and extend the service life of the hydrocyclone.

[0045] Function: Facilitates installation and fixation, improves stability, and reduces vibration.

[0046] Implementation principle: The fixing plate 6 secures the hydrocyclone to the equipment using bolts or other connection methods, ensuring the hydrocyclone maintains a stable position during operation and reducing damage caused by vibration. Simultaneously, the design of the fixing plate 6 also helps to disperse the stress generated during operation, further extending the service life of the hydrocyclone.

[0047] Product characteristics and performance parameters: The size of the fixed plate 6 is generally designed according to the size of the hydrocyclone and the installation requirements. The thickness is generally 5 to 10 mm, and the material is generally steel or other high-strength materials to ensure its strength and stability.
