Description

Technical Field

[0001] The present invention relates to the technical field of modified starch processing and filtration, and particularly to a modified starch processing and filtration device. Background Art

[0002] Modified starch is a new type of material obtained by physically, chemically or enzymatically treating natural starch extracted from raw materials such as corn, potato, wheat, etc. After the modification treatment, the properties of the starch are significantly enhanced. Modified starch usually has stronger heat resistance, antioxidant property, solubility, adhesiveness or other functional characteristics, and is widely used in multiple industries such as food, medicine, cosmetics, paper, etc. Modified starch usually appears as small white or nearly white particles with good fluidity, which is convenient for storage and transportation; in the processing of modified starch, sieving is a very crucial step, especially after drying and pulverization. Since larger particles, lumps or unreacted substances may be generated during the modification and drying of modified starch, it is necessary to remove these non-conforming impurities through sieving to ensure the uniformity of the particles, so as to facilitate subsequent use and ensure the consistency and quality of the product.

[0003] Currently, sieving of starch is usually carried out by screening methods such as vibrating screens and rotary screens. During the long-term sieving process, larger particles, lumps or impurities are likely to accumulate on the sieve plate. These accumulations slow down the sieving speed of the sieve mesh. Therefore, it is necessary to regularly deeply clean the impurity particles intercepted on the sieve mesh. It is necessary to disassemble the sieve plate through multiple operation steps to carry out the cleaning. At the same time, because some impurity particles will get stuck in the mesh holes of the sieve mesh, it takes a long time for each cleaning. Moreover, at the corners of the sieve mesh, larger particles or lumps are likely to accumulate, and these impurities are difficult to be completely cleaned, which will not only further prolong the cleaning time of the sieve mesh but also lead to a decrease in the permeability of the sieve mesh due to the difficulty of thorough cleaning. Summary of the Invention

[0004] The present invention provides a modified starch processing and filtration device, which solves the technical problems that during the sieving process, impurity particles will block the sieve holes and need to be regularly cleaned, but when cleaning the traditional sieve plate, it is troublesome and time-consuming because the impurity particles are stuck in the mesh holes, and some impurity particles accumulate at the corners of the sieve plate and are difficult to be completely removed, and the incomplete cleaning during regular cleaning reduces the permeability of the sieve mesh.

[0005] A modified starch processing and filtering device provided by the present invention includes an operation box with an open upper part. In the operation box, there is a tilting sieve filtering mechanism for multi-filtering modified starch and quickly discharging the sieved impurity particles without residue. A total driving mechanism for driving the tilting sieve filtering mechanism to operate is jointly arranged between the bottom of the operation box cavity and the tilting sieve filtering mechanism. The tilting sieve filtering mechanism includes: a shaft rod rotatably arranged on the total driving mechanism, several mounting seats fixedly connected at equal intervals between the left and right cavity walls of the operation box through fixing rods and distributed along the axial path of the shaft rod, a mounting ring rotatably connected by embedding on the mounting seat and sleeved outside the shaft rod, several annular sieve plates fixedly connected at equal intervals outside the shaft rod and corresponding to the mounting ring, and filter bags fixedly connected between the annular sieve plates and the mounting ring. The total driving mechanism is used to drive the shaft rod to move upward, thereby driving the filter bags to move upward and turn over to facilitate pouring out the impurity particles sieved out from the modified starch. The upper end surface of the mounting seat is a slope surface that is lower in the front and higher in the rear. A coupling component for connecting the two together for synchronous rotation is jointly arranged between the shaft rod and the mounting ring. A shielding component for sleeving outside the filter bags to prevent the modified starch from being thrown and floating during filtration is jointly arranged between the total driving mechanism and the inner cavity of the operation box. Several self-turning material components corresponding to the filter bags and located inside the corresponding filter bags are equidistantly arranged outside the shaft rod.

[0006] In a possible implementation manner, the total driving mechanism includes two electric telescopic rods symmetrically and fixedly connected to the bottom of the operation box cavity. The upper ends of the two electric telescopic rods are jointly fixedly connected with a mounting plate. A reciprocating driving motor is fixedly connected by embedding on the mounting plate. The output shaft of the reciprocating driving motor is fixedly connected to the lower end of the shaft rod through a coupling.

[0007] In a possible implementation manner, the shielding component includes a support plate, an arc-shaped cover, an inclined frame, and sliding columns. Spring telescopic column groups are respectively fixedly connected to the front and rear cavity walls of the operation box. The ends of the spring telescopic column groups are all fixedly connected with support plates. Arc-shaped covers corresponding to the filter bags are fixedly connected to the opposite sides of the two support plates through fixing columns. Inclined frames are fixedly connected to the opposite sides of the two support plates. Two L-shaped rods are symmetrically and fixedly connected to the front and rear of the left side of the mounting plate. The upper end of the vertical section of the L-shaped rod is fixedly connected with a spring telescopic column. A sliding column slidably arranged in the inclined frame is fixedly connected to the outside of the spring telescopic column.

[0008] In a possible implementation manner, the coupling component includes a sliding ring slidably connected to the outside of the shaft rod in a spline-fitting manner. A top spring is jointly fixedly connected between the sliding ring and the shaft rod. Several spoke plates are fixedly connected to the circumferential outer wall of the sliding ring at equal intervals in the circumferential direction. Several card slots corresponding to the number of spoke plates are circumferentially and equidistantly opened on the upper side of the mounting ring. A card block for cooperating with the card slot is fixedly connected to the lower end surface of the spoke plate.

[0009] In a possible implementation, a plurality of material guiding masks corresponding to the spoke plates and slip rings are fixedly connected to the outer wall of the shaft rod, and the material guiding masks are located directly above the corresponding spoke plates and slip rings.

[0010] In a possible implementation, the annular sieve plate is in an inverted cone shape that gradually inclines towards the side close to the axis of the shaft rod from bottom to top.

[0011] In a possible implementation, vertical grooves are formed in the left and right cavity walls of the operation box, and a guiding plate that is slidably arranged in the vertical grooves is rotatably connected to the outside of the shaft rod.

[0012] In a possible implementation, the self - tipping material component includes an annular recessed groove formed on the outside of the shaft rod, and a plurality of strip - shaped material - pushing plates are circumferentially and equidistantly hinged to the circumferential groove wall of the annular recessed groove through lugs.

[0013] In a possible implementation, a through - groove is formed in the lower part of the right end face of the operation box, and two L - shaped material guiding plates are symmetrically slidably connected in the front - and - back direction in the through - groove. Arc - shaped grooves are formed on the opposite sides of the horizontal sections of the L - shaped material guiding plates, and magnetic strip blocks are fixedly connected to the opposite ends of the horizontal sections of the two L - shaped material guiding plates, and the magnetic poles of the opposite sides of the two magnetic strip blocks are opposite.

[0014] In a possible implementation, a plurality of rectangular through - grooves that are flush with the front side of the mounting seat are equidistantly formed on the left and right wall plates of the operation box, and a receiving box is slidably connected in the two rectangular through - grooves that are opposite to each other left and right.

[0015] From the above technical solutions, it can be seen that the present invention has the following advantages: In the present invention, through the design of the tilting sifting mechanism, the combination of the shaft rod, the mounting ring and the annular sieve plate is used to push the filter bag upwards and turn it over after sieving, quickly and integrally pour out the impurity particles sieved down, achieving deep cleaning without complex disassembly, avoiding cleaning dead corners, shortening the shutdown time during each regular cleaning, and improving the screening efficiency and the continuity of sieving.

[0016] In the present invention, during the filtration process of the modified starch, the shaft rod reciprocally rotates to drive the strip - shaped material - pushing plates to stir the modified starch from multiple directions, promoting the uniform distribution of the material, keeping the starch particles in an active state during the filtration process, and thus accelerating the filtration speed of the modified starch.

Detailed implementation manners

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Please refer to Figure 1, the present invention provides a technical solution: a modified starch processing and filtering device, including an operation box 1 with an open upper part. In the operation box 1, there is a tilting sieve filtering mechanism 2 for multi-filtering the modified starch and quickly discharging the sieved impurity particles without residue. A total driving mechanism 3 for driving the tilting sieve filtering mechanism 2 to operate is jointly arranged between the bottom of the cavity of the operation box 1 and the tilting sieve filtering mechanism 2.

[0027] Please refer to Figure 2 , Figure 3 and Figure 5 , in this embodiment, the tilting sieve filtering mechanism 2 includes a shaft rod 21 rotatably arranged on the total driving mechanism 3, several mounting seats 22 fixedly connected at equal intervals between the left and right cavity walls of the operation box 1 through fixing rods and distributed along the axial path of the shaft rod 21, a mounting ring 23 rotatably connected by embedding on the mounting seat 22 and sleeved outside the shaft rod 21, several annular sieve discs 24 fixedly connected at equal intervals outside the shaft rod 21 and corresponding to the mounting ring 23, and a filter bag 25 fixedly connected between the annular sieve disc and the mounting ring 23. The total driving mechanism 3 is used to drive the shaft rod 21 to move upward, thereby driving the filter bag 25 to move upward and turn over so as to pour out the impurity particles sieved out from the modified starch. The annular sieve disc 24 is in an inverted cone shape that gradually inclines towards the side close to the axis of the shaft rod 21 from bottom to top.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , a coupling component 26 for connecting the shaft rod 21 and the mounting ring 23 together for synchronous rotation is jointly arranged between the shaft rod 21 and the mounting ring 23. A shielding component 27 for sleeving outside the filter bag 25 to prevent the modified starch from being thrown and flying during filtration is jointly arranged between the total driving mechanism 3 and the inner cavity of the operation box 1. Several self-turning and feeding components 28 corresponding to the filter bag 25 and located inside the corresponding filter bag 25 are equidistantly arranged outside the shaft rod 21. The self-turning and feeding component 28 includes an annular concave groove 281 opened outside the shaft rod 21. A plurality of strip-shaped feeding plates 282 are circumferentially and equidistantly hinged to the circumferential groove wall of the annular concave groove 281 through lugs. A through groove is opened at the lower part of the right end face of the operation box 1. Two L-shaped guide plates 6 are symmetrically slidably connected in the through groove. Arc-shaped grooves are opened on the opposite sides of the transverse sections of the two L-shaped guide plates 6. Magnetic strip blocks are fixedly connected to the opposite ends of the transverse sections of the two L-shaped guide plates 6, and the opposite sides of the two magnetic strip blocks have opposite magnetic poles.

[0029] Please refer to Figure 1 and Figure 2, the main driving mechanism 3 includes two electric telescopic rods 31 symmetrically and fixedly connected to the bottom of the cavity of the operation box 1. The upper ends of the two electric telescopic rods 31 are jointly and fixedly connected with a mounting plate 32. A reciprocating drive motor 33 is fixedly connected to the mounting plate 32 by embedding. The output shaft of the reciprocating drive motor 33 is fixedly connected to the lower end of the shaft rod 21 through a coupling.

[0030] In the initial state, the annular sieve plate 24 is located below the mounting ring 23, and the filter bag 25 is in a concave shape. Before filtering the modified starch, the two L-shaped guide plates 6 are simultaneously placed into the through groove, and the two L-shaped guide plates 6 are butted together by the magnetic strip blocks, so that the two L-shaped guide plates 6 jointly form a U-shaped frame. At the same time, the two arc-shaped grooves will also be butted together to jointly form a circular hole shape and be located outside the shaft rod 21. Then, the modified starch can be poured into the filter bag 25 at the uppermost part. Control the reciprocating drive motor 33 to operate to drive the shaft rod 21 to rotate intermittently and reciprocally. The shaft rod 21 then drives the mounting ring 23 to rotate through the coupling assembly 26. The shaft rod 21 also drives the annular sieve plate 24 to rotate. The mounting ring 23 and the annular sieve plate 24 then drive the filter bag 25 to rotate simultaneously.

[0031] During the rotation of the shaft rod 21, the strip-shaped dialing plate 282 will be driven to rotate. The strip-shaped dialing plate 282 is thrown outward and opened under the action of centrifugal force. The unfolded strip-shaped dialing plate 282 stirs the modified starch in the filter bag 25. When the shaft rod 21 switches the rotation direction, the unfolded strip-shaped dialing plate 282 will briefly stop, and then rotate downward and reset under its own weight. After the shaft rod 21 rotates in the other direction, the strip-shaped dialing plate 282 will be unfolded again under the action of centrifugal force, and can also stir the modified starch in the filter bag 25 vertically. By stirring the modified starch in the filter bag 25 from multiple directions by the strip-shaped dialing plate 282, the screening speed of the modified starch is accelerated. At the same time, the modified starch in the filter bag 25 will also move outward under the action of centrifugal force and disperse on the inner wall of the filter bag 25, further accelerating the screening speed.

[0032] The modified starch filtered by the filter bag 25 at the top will enter the covering component 27, and then fall into the second filter bag 25 from the top. By repeating the above filtering steps, the modified starch can be filtered multiple times. Finally, the filtered modified starch will be discharged from the filter bag 25 at the lowermost part, then fall onto the two L-shaped guide plates 6, and finally flow out along the inclined surface of the L-shaped guide plates 6, while the impurity particles in the modified starch are intercepted in the filter bag 25.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3, in this embodiment, the shielding assembly 27 includes a support plate 271, an arc-shaped cover 272, an inclined frame 273 and a sliding column 274. Spring telescopic column groups are fixedly connected to the front and rear cavity walls of the operation box 1 respectively, and support plates 271 are fixedly connected to the ends of the spring telescopic column groups. Arc-shaped covers 272 corresponding to the filter bags 25 are fixedly connected to the opposite sides of the two support plates 271 through fixing columns. Inclined frames 273 are fixedly connected to the opposite sides of the two support plates 271. Two L-shaped rods are symmetrically and fixedly connected to the left side of the mounting plate 32 in the front and rear. A spring telescopic column 275 is fixedly connected to the upper end of the vertical section of the L-shaped rod. A sliding column 274 slidably disposed in the inclined frame 273 is fixedly connected to the outside of the spring telescopic column 275.

[0034] Please refer to Figure 3 and Figure 4 , the coupling assembly 26 includes a sliding ring 261 slidably connected to the outside of the shaft rod 21 in a spline-fitting manner. A top spring is fixedly connected between the sliding ring 261 and the shaft rod 21. A plurality of spoke plates 262 are circumferentially and equidistantly fixedly connected to the outer circumferential wall of the sliding ring 261. A plurality of card slots 263 corresponding to the number of the spoke plates 262 are circumferentially and equidistantly formed on the upper side of the mounting ring 23. A card block 264 cooperating with the card slot 263 is fixedly connected to the lower end surface of the spoke plate 262. A plurality of material guiding shields 4 corresponding to the spoke plates 262 and the sliding ring 261 are fixedly connected to the outer wall of the shaft rod 21, and the material guiding shields 4 are located directly above the corresponding spoke plates 262 and the sliding ring 261. The slope on the upper surface of the material guiding shield 4 is used to guide the modified starch falling from above, preventing the modified starch from accumulating on the surfaces of the sliding ring 261 and the spoke plates 262.

[0035] Please refer to Figure 1 and Figure 2 , a plurality of rectangular through grooves flush with the front side of the mounting seat 22 are equidistantly formed on the left and right wall plates of the operation box 1. A receiving box 7 is slidably connected in the two relatively opposed rectangular through grooves. The upper end surface of the mounting seat 22 is a slope surface that is lower in the front and higher in the rear. A C-shaped baffle plate is fixedly connected to the upper end surface of the mounting seat 22. The C-shaped baffle plate is used to block the impurity particles falling on the upper surface of the mounting seat 22, ensuring that the impurity particles can smoothly enter the receiving box 7 along the slope of the mounting seat 22. Vertical grooves are formed on the left and right cavity walls of the operation box 1. A guiding plate 5 slidably disposed in the vertical groove is rotatably connected to the outside of the shaft rod 21. The guiding plate 5 is used to reinforce and support the upper part of the shaft rod 21, improving the stability of the shaft rod 21.

[0036] When it is necessary to remove the impurity particles in the filter bag 25, first manually slide the material receiving box 7 into the rectangular through groove, and then slide along the rectangular through groove so that the material receiving box 7 abuts against the front side of the mounting seat 22. Subsequently, separate the two docked L-shaped guide plates 6, then remove the L-shaped guide plate 6 from the working box 1. Then control the electric telescopic rod 31 to extend and push the mounting plate 32 upward. The mounting plate 32 then drives the shaft rod 21 to move upward through the reciprocating drive motor 33. The shaft rod 21 drives the slip ring 261 and the annular sieve plate 24 to move upward synchronously. The slip ring 261 drives the clamping block 264 to move out of the clamping groove 263 through the spoke plate 262, cutting off the transmission state between the shaft rod 21 and the mounting ring 23, and the annular sieve plate gradually pushes the filter bag 25 to move upward.

[0037] At the same time, the mounting plate 32 will also drive the L-shaped rod to move upward. The L-shaped rod then drives the sliding column 274 to move upward through the spring telescopic column 275. The sliding column 274 then squeezes against the inclined frame 273, causing the two inclined frames 273 to move away from each other. The inclined frame 273 then drives the arc-shaped cover 272 to move through the support plate 271 and the fixed column, so that the arc-shaped cover 272 gradually moves away from the outside of the filter bag 25. After the front and rear arc-shaped covers 272 are completely moved away, the sliding column 274 touches the upper groove wall of the inclined frame 273. The mounting plate 32 continues to move upward and drives the L-shaped rod to move synchronously. The L-shaped rod then squeezes the spring telescopic column 275 to be continuously compressed, and the shaft rod 21 gradually moves upward with the mounting plate 32 to drive the annular sieve plate 24 until the annular sieve plate 24 drives the filter bag 25 to turn upward into an inverted cone shape. The turned-up filter bag 25 causes the impurity particles inside it to pour out and fall on the mounting seat 22. Then the impurity particles flow forward along the inclined surface of the mounting seat 22 and fall into the material receiving box 7. Subsequently, control the shaft rod 21 to rotate several times reciprocally to drive the annular sieve plate 24 to move synchronously. The annular sieve plate 24 then drives the filter bag 25 to twist reciprocally, causing some of the impurities still attached to the inner wall of the filter bag 25 to fall off, so that the impurity particles intercepted during filtration can be quickly removed.

[0038] Then, control the electric telescopic rod 31 to contract, driving the mounting plate 32 to move downward. The mounting plate 32 indirectly drives the shaft rod 21 to move downward, and the shaft rod 21 drives the annular sieve plate 24 to move downward. The annular sieve plate 24 then presses the filter bag 25 to move downward until it returns to its initial shape. During the process that the filter bag 25 is gradually driven to concave downward, the mounting plate 32 drives the sliding column 274 to move downward through the L-shaped rod and the spring telescopic column 275. The sliding column 274 then makes the front and rear arc-shaped covers 272 move closer to each other through the cooperation with the inclined frame 273. The shaft rod 21 drives the clamping block 264 to move downward through the sliding ring 261 and the spoke plate 262, so that the clamping block 264 is inserted into the clamping groove 263 (even if the clamping block 264 is not clamped with the clamping groove 263, during the subsequent rotation of the shaft rod 21, the shaft rod 21 will drive the clamping block 264 to rotate synchronously through the sliding ring 261 and the spoke plate 262, and the top spring will continuously push the sliding ring 261 downward. When the clamping block 264 rotates to directly above the clamping groove 263, it will be indirectly inserted into the clamping groove 263 under the pushing of the top spring). Until finally the filter bag 25 is concave to its initial shape, the external modified starch can be passed into the filter bag 25 again for screening.

[0039] During operation, the filter bag 25 is initially in a concave shape. Pour the modified starch into the tilting screening mechanism 2, and perform multiple filtrations on the modified starch through the vertically distributed filter bag 25 in the tilting screening mechanism 2. After the filtration is completed, control the operation of the total driving mechanism 3 to make the filter bag 25 gradually turn up until the filter bag 25 becomes a convex shape, and then the impurity particles intercepted during the filtration process can be quickly discharged as a whole.
