Description

Technical Field

[0001] This utility model belongs to the technical field of solid-liquid separation equipment, specifically relating to a split-type suspension solid-liquid separation device. Background Technology

[0002] Currently, ammonium chloride in my country is mainly used as fertilizer, with a selling price of only a few hundred yuan per ton. The entire soda ash industry has a high inventory of ammonium chloride, resulting in low selling prices and reduced market competitiveness. Therefore, controlling the particle size of ammonium chloride crystals is a key means to enhance the product's market competitiveness. In the soda ash production process, ammonium chloride is produced using cold precipitation crystallization and salting-out crystallization methods. During the cold precipitation crystallization test, insoluble solid particles exist in the suspension. These solid particles are suspended in the liquid and need to be separated after the cold precipitation crystallization test is completed.

[0003] In existing solid-liquid separation devices, the centrifuge cylinders are all located inside the solid-liquid separation body and cannot move up and down. At the same time, there is also a roller inside the feed inlet, which makes it difficult to clean the solid impurities separated inside the centrifuge cylinder. This affects the solid-liquid separation effect after long-term use and makes it difficult to meet the usage requirements. To address this, our company has designed a split-type suspension solid-liquid separation device to solve the above technical problems. Utility Model Content

[0009] In a preferred embodiment, a drive motor is fixed to the bottom of the support frame, and the output shaft of the drive motor passes through the support frame and is fixedly connected to the bottom of the centrifuge cylinder.

[0010] As a preferred embodiment, the filter plate surface cleaning structure includes a push plate, two supports are provided on one side of the push plate, the supports are fixed to the surface of the housing, and multiple push rods are fixed on the surface of the supports.

[0011] In a preferred embodiment, one end of the multi-stage push rod passes through the housing and is fixedly connected to the surface of the push plate. The push plate is slidably connected to the surface of the multi-stage push rod.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 As shown, this utility model embodiment provides a split-type suspension solid-liquid separation device, specifically including a housing 1, a separation shell 2 fixedly connected to the top of the housing 1, a sealing cover 3 hinged to the surface of the separation shell 2, a hydraulic cylinder 4 fixedly fixed to the top of the housing 1, a connecting plate 5 fixedly fixed to the top of the hydraulic cylinder 4, and a slot for placing the connecting plate 5 is opened above the surface of the separation shell 2. A bearing ring 6 is fixed to the surface of the connecting plate 5. A centrifuge cylinder 7 is fixed to the inner wall of the bearing ring 6. A cleaning door 8 is hinged to the surface of the centrifuge cylinder 7. Multiple sieve holes are opened on the surface of both the centrifuge cylinder 7 and the cleaning door 8. A connecting rod 9 is fixed to the bottom of the connecting plate 5. A support frame 10 is fixed to the bottom of the connecting rod 9. A drive motor 11 is fixed to the bottom of the support frame 10. The output shaft of the drive motor 11 passes through the support frame 10 and is fixedly connected to the bottom of the centrifuge cylinder 7. A filter plate 12 and a liquid storage tank 13 are fixed to the inner wall of the casing 1. The liquid storage tank 13 is located below the filter plate 12. A drain valve 14 is fixed to the surface of the casing 1. The drain valve 14 communicates with the surface of the liquid storage tank 13. A cleaning structure is installed on the surface of the filter plate 12.

[0026] Specifically, in this embodiment, when the sealing cover 3 is open, the operator can directly add the suspension to be separated into the centrifuge cylinder 7. After closing the sealing cover 3, the drive motor 11 can drive the centrifuge cylinder 7 to rotate, and the centrifuge cylinder 7 can rotate on the surface of the bearing ring 6, so that the suspension inside the centrifuge cylinder 7 can achieve centrifugal separation. This allows the liquid to flow out of the centrifuge cylinder 7 and the cleaning door 8 through the sieve holes, while solid impurities can remain inside the centrifuge cylinder 7, achieving solid-liquid separation. The liquid flowing out of the centrifuge cylinder 7 can be filtered again by the filter plate 12. The filter plate 12 can intercept the fine impurities in the liquid a second time, achieving a more refined solid-liquid separation effect. The liquid storage tank 13 can store and retain the separated liquid. Opening the drain valve 14 can drain the liquid. When solid residue inside the centrifuge cylinder 7 needs to be removed... To clean, open the sealing cover 3 and activate the hydraulic cylinder 4. The hydraulic cylinder 4, through the connecting plate 5, drives the bearing ring 6 upward. At this time, the bearing ring 6 drives the centrifuge cylinder 7 to move together, and the connecting rod 9 drives the support frame 10 to move upward as well. This allows the centrifuge cylinder 7 to finally separate from the inside of the separation shell 2. This makes it easier for operators to clean the outer surface of the centrifuge cylinder 7 and the cleaning door 8, and makes it easier to clean impurities clogging the sieve holes. At the same time, operators can also open the cleaning door 8 to make it easier to remove impurities inside the centrifuge cylinder 7. The above design increases the convenience and thoroughness of cleaning, ensuring that every corner inside the centrifuge cylinder 7 can be thoroughly cleaned, meeting strict hygiene requirements, reducing the risk of cross-contamination, and allowing for timely detection and repair of potential problems to prevent equipment failure.

[0027] Please see Figures 1 to 5 As shown, the surface cleaning structure of the filter plate 12 includes a push plate 17. Two supports 15 are provided on one side of the push plate 17. The supports 15 are fixed to the surface of the housing 1. Multi-stage push rods 16 are fixed to the surface of the supports 15. One end of the multi-stage push rods 16 passes through the housing 1 and is fixedly connected to the surface of the push plate 17. The push plate 17 and the surface of the multi-stage push rods 16 are slidably connected. A collection shell 18 is fixedly connected to the surface of the housing 1. A sealing door 19 is hinged to the surface of the collection shell 18. In this embodiment, when the multi-stage push rods 16 are working, they can drive the push plate 17 to slide, so that the impurities on the surface of the filter plate 12 can be pushed into the collection shell 18 by the push plate 17. This allows the surface of the filter plate 12 to achieve an automatic cleaning effect. Opening the sealing door 19 can clean the impurities collected inside the collection shell 18.

[0028] Please see Figures 1 to 5As shown, two limiting blocks 22 are fixed to the surfaces of both the cleaning door 8 and the centrifuge cylinder 7. The limiting blocks 22 have through holes on their surfaces. The design of the limiting blocks 22 and the through holes allows the operator to fix the cleaning door 8 to the surface of the centrifuge cylinder 7 by using bolts through the through holes and installing nuts when the cleaning door 8 is closed, thus preventing the cleaning door 8 from opening automatically when the centrifuge cylinder 7 rotates. A guide rail 20 is fixed to the top of the support frame 10, and multiple sliders 21 are slidably connected to the surface of the guide rail 20. The tops of the sliders 21 are fixedly connected to the bottom of the centrifuge cylinder 7. The guide rail 20 provides a fixed track along which the sliders 21 slide, helping to maintain the centered position of the centrifuge cylinder 7, ensuring smoother and more accurate rotation, reducing offset and shaking, and improving rotational accuracy.

[0029] Please see Figures 1 to 5 As shown, a support ring 23 is fixed to the inner wall of the separator 2, and the surface of the support ring 23 is slidably connected to the surface of the support frame 10. The support ring 23 provides support to the support frame 10 located inside the separator 2, thereby bearing part of the load of the hydraulic cylinder 4. This reduces the wear and fatigue of the hydraulic cylinder 4, extends its service life, and reduces maintenance costs. The surface aperture of the filter plate 12 is smaller than the sieve aperture of the centrifuge cylinder 7 and the cleaning door 8. This design allows the centrifuge cylinder 7 to first separate and filter larger impurities, while the filter plate 12 can further separate and filter finer impurities, reducing the separation pressure of the centrifuge cylinder 7.

[0030] The specific working principle of this utility model is as follows: When the solid residue inside the centrifuge cylinder 7 needs to be cleaned, the sealing cover 3 is opened and the hydraulic cylinder 4 is activated, so that the hydraulic cylinder 4 can separate the centrifuge cylinder 7 from the separation shell 2. This makes it easier for the operator to clean the outer surface of the centrifuge cylinder 7 and the cleaning door 8, and makes it easier to clean the impurities clogging the sieve holes. At the same time, the operator can also open the cleaning door 8, so that the impurities inside the centrifuge cylinder 7 can be more easily removed. When the impurities on the surface of the filter plate 12 need to be cleaned, the multi-stage push rod 16 can drive the push plate 17 to slide, so that the impurities on the surface of the filter plate 12 can be pushed into the collection shell 18 by the push plate 17. Opening the sealing door 19 can clean the impurities collected inside the collection shell 18.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
