Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid-liquid separation device technology, and in particular to a solid-liquid separation device for the production of silicone resin flame retardants. Background Technology
[0002] Silicone resin flame retardants are a class of high-efficiency and environmentally friendly flame retardant additives with organosilicon resin as the core component. In the production of silicone resin flame retardants, solid-liquid separation is a key step, mainly used to separate the solid products and liquid media generated after the reaction or during the post-processing.
[0003] When separating silicone resin flame retardants, traditional solid-liquid separation devices suffer from several drawbacks. Firstly, the difficulty in adjusting the rotation speed during separation prevents fine particles from settling, resulting in impurities in the liquid and a decreased solids recovery rate. Secondly, the high water content of these impurities leads to incomplete dehydration, impacting subsequent filtration efficiency. Furthermore, the separated liquid contains impurities, necessitating further filtration using a filter screen. This requires operators to disassemble and clean the filter screen, making installation and disassembly cumbersome and reducing overall liquid filtration efficiency. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figures 1-4 A solid-liquid separation device for the production of silicone flame retardants includes a spiral separator 1. The spiral separator 1 is provided with multiple spiral blades. The multiple spiral blades are fixedly installed on the outer side wall of a first rotating shaft 8 by a clamping sleeve. A discharge hole is opened in the first rotating shaft 8. The mixture entering the spiral separator 1 flows out through the discharge hole. The mixture is separated into solid and liquid by centrifugal sedimentation and spiral conveying. This technology is prior art and will not be described in detail here.
[0022] Solid separation tank 2 and liquid separation tank 7 are fixedly installed on both sides of spiral separator 1 by bolt assembly, and solid separation tank 2 and liquid separation tank 7 are connected to spiral separator 1, so that the liquid separated by spiral separator 1 enters liquid separation tank 7 and the separated solids enter solid separation tank 2, which is convenient for operators to perform centralized processing.
[0023] The spiral separator 1 is also provided with a shaft platform 10. The first rotating shaft 8 is rotatably mounted at the end of the spiral separator 1 through a rotating assembly, and the first rotating shaft 8 extends into the spiral separator 1. The liquid inlet pipe 11 is inserted at the end of the first rotating shaft 8. The rotary joint 12 is mounted at the end of the liquid inlet pipe 11 through a clamping sleeve, and the end of the rotary joint 12 is fixedly connected to the first rotating shaft 8 through a bolt assembly, so that the first rotating shaft 8 is connected to the liquid inlet pipe 11 through the rotary joint 12. This arrangement prevents the first rotating shaft 8 from driving the liquid inlet pipe 11 to rotate, which would damage the liquid inlet pipe 11 and affect the subsequent conveying efficiency.
[0024] Multiple connecting rods 9 are circumferentially fixed at the end of the first rotating shaft 8 by bolt assemblies. A rotating ring 13 is fixed at the end of the multiple connecting rods 9 by bolt assemblies. The first rotating shaft 8 is coaxially connected to the shaft platform 10 through the rotating ring 13, and the end of the rotating ring 13 is rotatably connected to the end of the shaft platform 10 through a rotating assembly. An electric push rod 14 is fixed to the side wall of the shaft platform 10 by bolt assemblies. This arrangement facilitates adjustment by the operator.
[0025] The support plate 15 is fixedly mounted on the output end of the electric push rod 14 by bolt assembly, the drive motor 16 is fixedly mounted on the end of the support plate 15 by bolt assembly, a shock-absorbing pad is provided between the drive motor 16 and the support plate 15, and the second rotating shaft 18 is coaxially fixedly mounted on the output end of the drive motor 16 by clamping sleeve, thereby providing driving force for the second rotating shaft 18.
[0026] The third rotating shaft 22 is coaxially fixed at the end of the rotating ring 13 via a clamping sleeve. The fourth gear 21 is coaxially fixed at the outer wall of the third rotating shaft 22 via a key. The third gear 20 is coaxially fixed at the end of the third rotating shaft 22 via a key. This configuration provides power transmission to the third rotating shaft 22.
[0027] The shaft platform 10 is equipped with an adjustment component for adjusting the rotation speed of the first rotating shaft 8, and the second rotating shaft 18 is connected to the adjustment component. The adjustment component includes a first gear 17 and a second gear 19. The first gear 17 is coaxially fixed to the outer wall of the second rotating shaft 18 by a key, and the second gear 19 is coaxially fixed to the end of the second rotating shaft 18 by a key. The distance between the first gear 17 and the second gear 19 is greater than the distance between the third gear 20 and the fourth gear 21. This arrangement prevents the first gear 17 and the second gear 19 from colliding with the third gear 20 and the fourth gear 21 during operation, which could cause mechanical failure and affect the subsequent separation efficiency.
[0028] It should be noted that, due to the different diameters of the first gear 17 and the second gear 19 compared to the third gear 20 and the fourth gear 21, this setting adjusts the rotational speed of the first rotating shaft 8, thereby improving the separation efficiency within the spiral separator 1 and increasing the equipment's adaptability to different dosages of flame retardants.
[0029] The delivery pipe 6 is inserted into the end of the liquid separation tank 7 via a bolt assembly, and the filter box 4 is fixedly installed at the end of the delivery pipe 6 via a bolt assembly. The filter box 4 contains a filter screen 5 and a limiting assembly for limiting the position of the filter screen 5. The liquid collection tank 3 is fixedly installed on the side wall of the filter box 4 via a bolt assembly. The limiting assembly includes a spring 23 and a sliding plate 24. Multiple sliding grooves are symmetrically opened on the filter screen 5. One end of the spring 23 is fixedly installed on the inner side wall of the sliding groove via a hook, and the other end of the spring 23 is fixedly installed on the end of the sliding plate 24 via a hook. The sliding plate 24 is installed on the inner side wall of the sliding groove via a sliding groove slider assembly. This configuration provides driving force for the limiting rod 25, making it convenient for the operator to adjust the limiting rod 25.
[0030] The limiting assembly also includes a limiting rod 25. Limiting holes are symmetrically opened on the side wall of the filter screen 5. The end of the limiting rod 25 is fixedly set at the end of the sliding plate 24 by a bolt assembly, and the limiting rod 25 extends into the limiting hole, so that the limiting rod 25 plays a limiting role on the sliding plate 24, making it convenient for operators to install and replace the filter screen 5.
[0031] The aforementioned bolt assembly, rotating assembly, and sliding block assembly are all prior art. The bolt assembly includes a bolt and a threaded hole for threading two components together. The rotating assembly includes a rotating groove, an annular block, and an annular groove. The annular groove is formed on the inner wall of the rotating groove, and the annular block rotates within the annular groove. The sliding block assembly includes a slider and a sliding groove, and the slider slides within the sliding groove.
[0032] The functional principle of this utility model can be explained through the following operation methods:
[0033] The operator inputs the flame retardant into the first rotating shaft 8 through the inlet pipe 11 and the rotary joint 12. The flame retardant enters the spiral separator 1 through the first rotating shaft 8. The electric push rod 14 drives the support plate 15 to move, and the support plate 15 drives the drive motor 16 to move, so that the second gear 19 and the third gear 20 mesh with each other. The drive motor 16 drives the second rotating shaft 18 to rotate, and the second rotating shaft 18 drives the second gear 19 to rotate. The second gear 19 drives the third rotating shaft 22 to rotate through the third gear 20. The third rotating shaft 22 drives the first rotating shaft 8 to rotate through the rotating ring 13 and the connecting rod 9, thus separating the flame retardant.
[0034] When it is necessary to increase the speed of the first rotating shaft 8, the electric push rod 14 drives the support plate 15 to move, the support plate 15 drives the drive motor 16 to move, so that the first gear 17 and the fourth gear 21 mesh with each other, the drive motor 16 drives the second rotating shaft 18 to rotate, the second rotating shaft 18 drives the first gear 17 to rotate, and the first gear 17 drives the third rotating shaft 22 to rotate through the fourth gear 21, thereby increasing the speed of the first rotating shaft 8.
[0035] The separated solids enter the solid separation tank 2, and the separated liquids enter the liquid separation tank 7. Since the liquids still contain some impurities, the liquids enter the filter tank 4 through the conveying pipe 6, and the liquids are filtered through the filter screen 5 and enter the liquid collection tank 3.
[0036] When the filter 5 needs to be replaced, the operator moves the sliding plates 24 on both sides. The sliding plates 24 compress the spring 23, and the sliding plates 24 drive the limit rod 25 to move. The limit rod 25 releases the limit on the filter 5.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
