DETAILED DESCRIPTION

[0020] The utility model is clearly described below in combination with the drawings in the embodiment of the utility model and specific embodiment, and the description here is only used to explain the utility model, but not as the limitation to the utility model. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor, any modification, equivalent replacement, improvement etc. should be contained in the protection scope of the utility model.

[0021] Embodiment 1

[0022] As Figures 1-4As shown, this utility model provides a solid-liquid separation device for tert-butylamine recovery, including a housing 1 with an opening at the top; a partition 2 is provided inside the housing 1, dividing the housing 1 into a filtrate chamber and a filter residue chamber 11; a drain port 4 is provided at the bottom of the filtrate chamber, and a residue discharge port 3 is provided at the bottom of the filter residue chamber 11; both the drain port 4 and the residue discharge port 3 are equipped with switch valves; a filter cylinder with openings at both ends is provided inside the filtrate chamber, one end of which is connected to a connecting plate 13, and a feed pipe 14 is fixedly connected to the connecting plate 13, with one end of the feed pipe 14 penetrating through the housing. The filter cartridge is rotatably connected to the housing 1 via a bearing. A gear 1 is fixed on the feed pipe 14 located outside the housing 1. The gear 1 is connected to a gear 2 via a chain 16. The gear 2 is connected to a stepper motor 17. The feed pipe 14 located outside the housing 1 is rotatably connected to a guide pipe 15 via a bearing. The guide pipe 15 is connected to a feed hopper 18. The feed hopper 18 is fixedly connected to the outer wall of the housing 1. The other end of the filter cartridge is connected to a connecting ring 8. A discharge port is provided on the partition 2 corresponding to the connecting ring 8. The outer wall of the connecting ring 8 is rotatably connected to the inner wall of the discharge port via a bearing.

[0023] The filter cylinder has a matching feeding screw, which includes a rotating rod 6 and a feeding blade 10. One end of the rotating rod 6 passes through the discharge port and the filter cake chamber 11 in sequence and is connected to a stepper motor 7. The feeding blade 10 is fixed in a spiral shape inside the filter cylinder.

[0024] The filter cartridge consists of two semi-cylindrical filter screens 5, and the two filter screens 5 are detachably connected to the connecting plate 13 and the connecting ring 8, respectively.

[0025] A connecting pipe 9 is fixedly connected to one side of the connecting ring 8 corresponding to the filtrate chamber. Both the connecting pipe 9 and the connecting plate 13 are provided with a locking block 12, and the filter screen 5 corresponding to the locking block 12 is provided with a matching locking groove.

[0026] The lower end of the locking block 12 is fixedly connected to the connecting plate 13 or the connecting pipe 9. Both sides of the other end of the locking block 12 are provided with receiving grooves 21. A limiting block 20 is provided in the receiving groove 21. The side of the limiting block 20 away from the receiving groove 21 is an inclined surface. The upper end of the limiting block 20 is hinged to the inner wall of the receiving groove 21 through a hinge shaft 22. The lower end of the limiting block 20 is fitted with a compression spring 23. The other end of the compression spring 23 is connected to the inner wall of the receiving groove 21. The limiting block 20 can be pressed into the receiving groove 21 by pressing the limiting block 20. When installing filter screen 5, the slot on filter screen 5 corresponds to the locking block 12. Pressing down on filter screen 5 causes the limiting block 20 to retract into the receiving groove 21 under pressure, and the locking block 12 passes through the slot. Subsequently, the limiting block 20 extends out of the receiving groove 21 under the action of the compression spring 23, limiting the filter screen 5 and preventing the locking block 12 from coming out of the slot. When it is necessary to remove or thoroughly clean filter screen 5, press the limiting block 20 to push it into the receiving groove 21, and filter screen 5 can be removed. This facilitates cleaning of filter screen 5, and during cleaning, each filter screen 5 can be cleaned one by one. When cleaning the upper filter screen 5, the lower filter screen 5 can continue to work without interrupting the filtration operation, ensuring the continuity of filtration and further improving work efficiency.

[0027] The filter screen 5 has a protrusion 19 and a groove on each of its two straight edges, and the protrusion 19 and groove correspond to the groove and protrusion 19 on the other filter screen 5, respectively. This arrangement improves the stability between the two filter screens 5.

[0028] Material enters the filter cartridge from the feed hopper. Stepper motor one drives the filter cartridge to rotate, filtering the material. Filtrate enters the filtrate chamber and exits through the drain port, while filter residue remains inside the filter cartridge. Stepper motor two drives the feeding screw to rotate, transporting the filter residue from the filter cartridge towards the discharge port, finally entering the filter residue chamber. This feature allows for timely discharge of filter residue, minimizing its impact on filtration and achieving continuous, high-efficiency filtration. During filtration, stepper motor one continuously rotates the filter cartridge, fully utilizing the filter screen and improving filtration efficiency. It also allows for the disassembly and cleaning of the filter screen. Specifically, to remove one filter screen, position it at the top, press the limiting block to push it into the receiving groove, and release the limiting block, allowing the screen to be removed for cleaning. While cleaning the upper filter screen, the lower filter screen continues to operate, ensuring uninterrupted filtration and further improving efficiency.

[0029] Example 2

[0030] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the feed end of the filter cartridge is lower than the discharge end of the filter cartridge. This prevents material from entering the filter cake chamber without proper filtration when the flow rate is too high.

[0031] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
