Description

Technical Field

[0001] The utility model relates to the technical field of stevioside production, in particular to a residue extrusion device for stevioside production. Background Technique

[0002] In the process of stevioside production, the treatment of residues is an important link, and the residue extrusion device plays a key role in reducing waste discharge and improving raw material utilization rate.

[0003] Traditional devices usually adopt a fixed extrusion screen structure. During long-term use, the residues will gradually block the pores of the screen, affecting the extrusion effect and efficiency. Since the position of the screen is fixed, it is very difficult to clean. It often takes a lot of manpower and time to disassemble and clean. In large-scale stevioside production, frequent shutdowns to clean the screen will seriously affect the production progress and increase production costs. For this reason, we propose a residue extrusion device for stevioside production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a residue extrusion device for stevioside production to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A residue extrusion device for stevioside production, including an extrusion cylinder, an extrusion assembly is installed outside the extrusion cylinder and passes through the inner cavity of the extrusion cylinder, a plurality of fixing plates are installed outside the extrusion cylinder, a movable rod is slidably penetrated through the surface of the fixing plate, a circular connecting plate is installed at the bottom of the plurality of movable rods, and a rotatable screen assembly is installed inside the circular connecting plate;

[0006] A limiting plate is rotatably installed at the upper end of the movable rod, a plurality of cross plates corresponding to the movable rod in position are fixedly installed outside the extrusion cylinder, a limiting hole is opened on the surface of the cross plate, the movable rod passes through the limiting hole, and an elastic component is arranged at the bottom surface of the limiting plate.

[0007] Preferably, the extrusion assembly includes a connecting plate, the connecting plate is installed outside the extrusion cylinder, a hydraulic push rod is installed on one side of the connecting plate, and one end of the inner rod of the hydraulic push rod is installed with a pressing block that can pass through the inner cavity of the extrusion cylinder.

[0008] Preferably, the screen assembly includes an installation sleeve and an extrusion screen, the installation sleeve is rotatably installed inside the circular connecting plate, and the extrusion screen is fixedly installed inside the installation sleeve.

[0009] Preferably, the horizontal length of the limiting plate matches the vertical length dimension of the limiting hole, and the vertical length of the limiting plate matches the horizontal length dimension of the limiting hole.

[0010] Preferably, the elastic component includes a stop block and a torsion spring. The stop block is fixedly installed on the outer side of the movable rod. The lower end of the torsion spring is installed on the top surface of the stop block, and the upper end of the torsion spring is fixedly installed on the bottom surface of the limit plate.

[0011] Preferably, the torsion spring passes through the inner side of the limit hole.

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

[0013] 1. For the residue extrusion device for stevioside production, after the extrusion work is completed, rotate the limit plate so that the limit plate corresponds to the position of the limit hole in the vertical direction, so that the limit plate can move downward through the limit hole. When the limit plate passes through the limit hole, control the overall downward movement of the limit plate and the movable rod until the stop block abuts against the fixed plate. The movable rod can drive the mounting sleeve and the extrusion screen net to move downward through the annular connecting plate. At this time, the residue in the extrusion cylinder can be discharged through the space between the extrusion cylinder and the extrusion screen net, which is convenient for collecting the extruded residue.

[0014] 2. For the residue extrusion device for stevioside production, after the residue collection is completed, since the mounting sleeve is already at a certain distance from the bottom surface of the extrusion cylinder, the mounting sleeve can be rotated at this time to make the extrusion screen net rotate. By adjusting the angle of the extrusion screen net and using a water spray head to backflush the extrusion screen net, the residue remaining on the surface of the extrusion screen net can be effectively cleaned, thus ensuring the efficiency of residue cleaning.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 As shown, the present invention provides a dregs extrusion device for stevioside production, including an extrusion cylinder 1. An extrusion assembly passing through the inner cavity of the extrusion cylinder 1 is installed outside the extrusion cylinder 1. A plurality of fixing plates 5 are installed outside the extrusion cylinder 1. A movable rod 6 is slidably penetrated and installed on the surface of the fixing plate 5. A circular connecting plate 7 is installed on the bottom surfaces of the plurality of movable rods 6. A rotatable screen assembly is installed inside the circular connecting plate 7;

[0023] A limiting plate 12 is rotatably installed at the upper end of the movable rod 6. A plurality of cross plates 10 corresponding to the movable rod 6 in position are fixedly installed outside the extrusion cylinder 1. A limiting hole 11 is opened on the surface of the cross plate 10. The movable rod 6 passes through the limiting hole 11, and an elastic assembly is arranged on the bottom surface of the limiting plate 12.

[0024] Specifically, control the limiting plate 12 to rotate to a suitable position with the limiting hole 11, so that the limiting plate 12 can move downward, so that the installation sleeve 8 is separated from the bottom surface of the extrusion cylinder 1 by a certain distance, so that while facilitating the discharge of dregs, the extrusion screen 9 can be rotated and the extrusion screen 9 can be backflushed and cleaned.

[0025] Among them: The extrusion assembly includes a connecting plate 2. The connecting plate 2 is installed outside the extrusion cylinder 1. A hydraulic push rod 3 is installed on one side of the connecting plate 2. One end of the inner rod of the hydraulic push rod 3 is installed with a pressing block 4 that can pass through the inner cavity of the extrusion cylinder 1. Turning on the switch of the hydraulic push rod 3 drives the pressing block 4 to move downward, and can extrude the dregs in the inner cavity of the extrusion cylinder 1.

[0026] Among them: The screen assembly includes an installation sleeve 8 and an extrusion screen 9. The installation sleeve 8 is rotatably installed inside the circular connecting plate 7. The extrusion screen 9 is fixedly installed inside the installation sleeve 8. The dregs are extruded in the extrusion cylinder 1, and the effective substances therein can flow out through the extrusion screen 9.

[0027] Among them: The transverse length of the limiting plate 12 matches the longitudinal length of the limiting hole 11, and the longitudinal length of the limiting plate 12 matches the transverse length of the limiting hole 11, so that after the limiting plate 12 rotates a certain angle, it can pass through the limiting hole 11.

[0028] Among them: The elastic component includes a stop block 13 and a torsion spring 14. The stop block 13 is fixedly installed on the outer side of the movable rod 6. The lower end of the torsion spring 14 is installed on the top surface of the stop block 13. The upper end of the torsion spring 14 is fixedly installed on the bottom surface of the limit plate 12. The torsion spring 14 passes through the inner side of the limit hole 11. In the natural state of the torsion spring 14, the limit plate 12 and the limit hole 11 are in a misaligned state. In this state, the limit plate 12 cannot vertically pass through the limit hole 11.

[0029] Working principle: The present utility model is a residue extrusion device for stevioside production. When in use, first control the hydraulic push rod 3 to drive the pressing block 4 to rise away from the extrusion cylinder 1. Then put the residue into the extrusion cylinder 1. Turn on the switch of the hydraulic push rod 3 to control the pressing block 4 to move downward, so as to extrude the residue. The effective components in the residue flow out through the extrusion screen 9, while the residue is blocked above the extrusion screen 9. After the extrusion work is completed, rotate the limit plate 12 so that the limit plate 12 corresponds to the position of the limit hole 11 in the vertical direction, so that the limit plate 12 can pass through the limit hole 11 and move downward. When the limit plate 12 passes through the limit hole 11, control the limit plate 12 and the movable rod 6 as a whole to continue to move downward until the stop block 13 abuts against the fixed plate 5. The movable rod 6 can drive the mounting sleeve 8 and the extrusion screen  9 to move downward through the annular connecting plate 7. At this time, the residue in the extrusion cylinder 1 can be discharged through the space between the extrusion cylinder 1 and the extrusion screen 9, which is convenient for collecting the extruded residue.

[0030] After the residue collection is completed, since the mounting sleeve 8 is already at a certain distance from the bottom surface of the extrusion cylinder 1, the mounting sleeve 8 can be rotated at this time to make the extrusion screen 9 rotate. By adjusting the angle of the extrusion screen 9 and using a water spray head to backflush the extrusion screen 9, the residue remaining on the surface of the extrusion screen 9 can be effectively cleaned, thus ensuring the efficiency of cleaning the residue.
