Description

Technical Field

[0001] This utility model relates to a flocculation and impurity removal device for processing steviol glycosides, belonging to the field of steviol glycoside technology. Background Technology

[0002] Stevia, also known as stevioside, is a glycoside extracted from the leaves of plants in the Asteraceae family. Stevioside can be extracted, clarified, and crystallized from dried leaves using water. After flocculation treatment, stevioside is usually filtered using a filter press to remove impurities.

[0003] Chinese Patent Publication No. (CN 221061891 U) discloses a hydraulic filtration device for extracting steviol glycosides, comprising: a steviol glycoside raw material extrusion box, a filter plate, and a percolation box, wherein the filter plate is located between the steviol glycoside raw material extrusion box and the percolation box; and a filter extrusion assembly disposed on the outer wall of the steviol glycoside raw material extrusion box; wherein the filter extrusion assembly comprises: a first hydraulic cylinder disposed on the outer wall of the steviol glycoside raw material extrusion box; a first filter extrusion plate disposed at the output end of the first hydraulic cylinder; and a feed inlet disposed at the top of the steviol glycoside raw material extrusion box; wherein, during the hydraulic movement of the cleaning plate, a filter hole insertion rod is inserted into the filter hole on the filter plate, and the steviol glycoside raw material embedded in the filter hole is pushed out, ensuring that the filter hole has liquid flow capability, thereby achieving solid-liquid separation of the steviol glycoside raw material under the extrusion of the first filter extrusion plate and the second filter extrusion plate. The filter plates of the above-mentioned device are installed and fixed. When cleaning the filter plates, the insertion rods are set in the same horizontal direction as the filter holes and inserted into the filter holes to clean the filter plates. However, in actual use, due to long-term industrial vibration, pressure deformation and thermal expansion and contraction of the equipment, the insertion rods may have slight deviations. When the misaligned insertion rods are inserted into the filter holes, the insertion rods will stick into the surface of the filter plates and cannot properly clean the impurities in the filter holes. At the same time, it may also damage the filter plates.

[0004] To address this, a flocculation and impurity removal device for stevioside processing is proposed. Utility Model Content

[0006] The technical solution of this utility model is achieved as follows: a flocculation and impurity removal device for processing steviol glycosides, comprising: A filter press assembly includes a filter press chamber, a feed pipe connected to the top of the filter press chamber, a drain valve fixedly installed at the bottom of the filter press chamber, a hydraulic cylinder fixedly installed at the rear of the filter press chamber, a filter plate fixedly installed at the front of the hydraulic cylinder, a discharge port at the bottom of the filter press chamber, a first sealing baffle connected to the bottom of the filter press chamber by bolts and threads, a second sealing baffle connected to the top of the filter press chamber by bolts and threads, a filter plate provided at the front of the inner cavity of the filter press chamber, and insertion holes provided on both the left and right sides of the filter plate. The assembly / disassembly component includes a housing. Two housings are fixedly installed on the left and right sides of the filter press box.

A movable frame is fixedly connected to the other end of each spring. A second trapezoidal block is fixedly installed on the upper and lower sides of each of the two movable frames. The top of each of the four second trapezoidal blocks contacts the bottom of each of the four first trapezoidal blocks. An insert block is fixedly installed on the inner side of each of the four second trapezoidal blocks.

[0007] More preferably, the threads on the upper and lower sides of the bidirectional screw surface are in opposite directions, and the thread pitch on the upper and lower sides of the bidirectional screw surface is the same.

[0008] More preferably, the filter press box has a slot in its inner cavity, and the filter plate is inserted into the inner cavity of the slot.

[0009] More preferably, slots are provided on both the left and right sides of the filter press box, and the insert block passes through the inner cavity of the slot and is inserted into the inner cavity of the insertion hole.

[0014] The present invention has the following advantages due to the adoption of the above technical solution: I. This utility model, through the setting of a disassembly and assembly component, allows the first trapezoidal block to press against the second trapezoidal block by rotating the knob, thereby inserting the insert into the inner cavity of the insertion hole and fixing the filter plate. Reverse rotation of the knob releases the first trapezoidal block from the second trapezoidal block, at which point the spring, through its own tension, pulls the insert outward, causing the insert to move out of the inner cavity of the insertion hole and releasing the filter plate from fixation.

By setting a slot, the movement of the insert block can be limited, preventing the insert block from shifting during movement and thus affecting the quick assembly and disassembly of the filter plate. By setting a guide rod, the movement of the moving frame can be limited, ensuring the stability of the moving frame during movement. By setting a limiting groove, the movement of the screw block can be limited, preventing the screw block from rotating synchronously with the bidirectional screw. By setting anchor bolts, the overall equipment can be stabilized, preventing the equipment from shaking due to accidental collisions.

Detailed Implementation

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 like Figure 1-6 As shown, this utility model embodiment provides a flocculation and impurity removal device for steviol glycoside processing, comprising: The filter press assembly 1 includes a filter press box 101. The top of the filter press box 101 is connected to a feed pipe 102. A drain valve 103 is fixedly installed at the bottom of the filter press box 101. A hydraulic cylinder 104 is fixedly installed at the rear side of the filter press box 101. A filter plate 105 is fixedly installed at the front side of the hydraulic cylinder 104. A discharge port 106 is opened at the bottom of the filter press box 101. A first sealing baffle 107 is connected to the bottom of the filter press box 101 by bolt thread. A second sealing baffle 110 is connected to the top of the filter press box 101 by bolt thread. A filter plate 108 is provided at the front side of the inner cavity of the filter press box 101. Insertion holes 109 are opened on both the left and right sides of the filter plate 108. The disassembly and assembly component 2 includes a housing 201. Two housings 201 are fixedly installed on the left and right sides of the filter press box 101. A knob 202 is movably connected to the top of each housing 201. A bidirectional screw 203 is fixedly connected to the bottom of each knob 202. Screw blocks 204 are threadedly connected to the upper and lower sides of the surface of each bidirectional screw 203. A first trapezoidal block 205 is fixedly installed on the inner side of each of the four screw blocks 204. A spring 209 is fixedly connected to the inner cavity of each housing 201. A movable frame 208 is fixedly connected to the other end of each spring 209. A second trapezoidal block 206 is fixedly installed on the upper and lower sides of each movable frame 208. The top of each of the four second trapezoidal blocks 206 contacts the bottom of each of the four first trapezoidal blocks 205. An insert block 207 is fixedly installed on the inner side of each of the four second trapezoidal blocks 206. The threads on the upper and lower sides of the surface of the bidirectional screw 203 are in opposite directions, and the thread spacing on the upper and lower sides of the surface of the bidirectional screw 203 is the same.

[0023] By setting up the disassembly and assembly component 2, rotating the knob 202 causes the first trapezoidal block 205 to press against the second trapezoidal block 206, thereby inserting the insertion block 207 into the inner cavity of the insertion hole 109 to fix the filter plate 108. Reverse rotation of the knob 202 releases the first trapezoidal block 205 from pressing against the second trapezoidal block 206. At this time, the spring 209 can pull the insertion block 207 outward through its own tension, causing the insertion block 207 to move out of the inner cavity of the insertion hole 109 and releasing the fixation of the filter plate 108. This method can realize the quick disassembly and assembly of the filter plate 108, which is convenient when the filter holes on the surface of the filter plate 108 become blocked. It is also convenient for operators to clean the filter plate 108, reduce the disassembly and assembly time of the filter plate 108, reduce the overall downtime of the equipment, improve the convenience of equipment use, and facilitate the operation of the operator.

[0024] Example 2 like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, a slot 210 is provided in the inner cavity of the filter press 101, and the filter plate 108 is inserted into the inner cavity of the slot 210. Slots 211 are provided on both the left and right sides of the filter press 101. The insert block 207 passes through the inner cavity of the slot 211 and is inserted into the inner cavity of the insertion hole 109. The inner cavity of the insertion hole 109 and the inner cavity of the slot 211 are interconnected. The inner cavity of the insertion hole 109 and the inner cavity of the slot 211 are in the same horizontal direction. Guide rods 212 are fixedly installed in the inner cavities of the two housings 201. The two moving frames 208 are slidably connected to the surfaces of the two guide rods 212. Limiting grooves 213 are provided on the surfaces of the two housings 201. The outer sides of the four screw blocks 204 are slidably connected to the inner cavities of the four limiting grooves 213. Anchor bolts 111 are threadedly connected to the front and rear sides of the bottom of the filter press 101. The bottom of the anchor bolts 111 is threadedly connected to the ground.

[0025] By setting the slot 210, the position of the filter plate 108 can be initially limited, thus facilitating the insertion of the plug 207 into the inner cavity of the insertion hole 109. By setting the slot 211, the movement of the plug 207 can be limited, preventing the plug 207 from shifting during movement, which would affect the quick assembly and disassembly of the filter plate 108. By setting the guide rod 212, the movement of the moving frame 208 can be limited, ensuring the stability of the moving frame 208 during movement. By setting the limiting groove 213, the movement of the screw block 204 can be limited, preventing the screw block 204 from rotating synchronously with the bidirectional screw 203. By setting the anchor bolts 111, the overall equipment can be stabilized, preventing the equipment from shaking due to accidental collisions.

[0026] In operation, this invention works as follows: The flocculated steviol glycoside solution is injected into the inner cavity of the filter press 101 through the feed pipe 102. Then, the extension of the hydraulic cylinder 104 causes the filter plate 105 to press the flocculated steviol glycoside solution forward. At this time, the filter plate 108 filters and removes impurities from the flocculated steviol glycoside solution. Clean liquid passes through the filter plate 108, while impurities remain on the rear side of the filter plate 108. The filtered and impurity-removed steviol glycoside solution is discharged through the drain valve 103. Then, by disassembling the first sealing baffle 107, the operator can remove the impurities from the inner cavity of the filter press 101 through the discharge port 106, thus achieving the impurity removal and filtration of the flocculated steviol glycoside solution. When the filter plate 108 becomes clogged after prolonged use, rotating the knob 202 causes the bidirectional screw 203 to move the screw block 204 up and down. Simultaneously, the screw block 204 moves the first trapezoidal block 205 to both sides. 5. Release the pressure on the second trapezoidal block 206. At this time, the spring 209 deforms due to the loss of force. Through its own tension, the spring 209 causes the moving frame 208 to move the second trapezoidal block 206 and the insert block 207 outward. The insert block 207 moves out of the inner cavity of the insertion hole 109. At this time, disassemble the second sealing baffle 110 and pull the filter plate 108 upward to complete the disassembly of the filter plate 108. After cleaning the filter plate 108, remove the filter plate... 108 is inserted into the inner cavity of the slot 210 again. Then, the knob 202 is rotated in the opposite direction, causing the bidirectional screw 203 to drive the screw block 204 and the first trapezoidal block 205 to move inward. The first trapezoidal block 205 presses the second trapezoidal block 206. At this time, the second trapezoidal block 206 moves inward, and the spring 209 deforms again. The second trapezoidal block 206 drives the insert block 207 to be inserted into the inner cavity of the insertion hole 109, thus realizing the installation of the filter plate 108.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
