Description

Technical Field

[0001] The present invention relates to the technical field of slag removal processes, and particularly to a slag removal and clarification process based on the production of ancient method maltose. Background Art

[0002] Ancient method maltose is a traditional Chinese candy, mainly made from starch and syrup. The production process emphasizes natural raw materials and manual skills. In the production process, wheat germinates (i.e., malt) and is mixed with glutinous rice for fermentation to saccharify the glutinous rice. The process lies in the fact that malt contains rich saccharifying enzymes to promote the generation of saccharification. The process of separating solid impurities (such as incompletely dissolved malt residues, glutinous rice residues, etc.) in the saccharified mixture is the slag removal process.

[0003] In the production process of ancient method maltose or similar candies, using gauze to squeeze out the sugar solution to achieve slag removal is a common operation method. This method mainly utilizes the filtering effect of gauze. The mixture is wrapped with gauze and squeezed. Solid particles and impurities in the sugar solution are retained on the gauze, while pure sugar solution flows out through the gauze, thus achieving slag removal. However, the above-mentioned slag removal process has many limitations, such as:

[0004] The filtration efficiency is relatively low. The filtration pore size of the gauze is relatively large and is easily blocked, resulting in a reduction in the filtration speed. This causes the entire filtration process to possibly take a long time and affects the production efficiency;

[0005] The extrusion force is not easy to control. During the extrusion process, the gauze may be damaged due to uneven force or excessive extrusion, resulting in the mixing of the sugar solution and solid residues, affecting the purity of the sugar solution. And if the extrusion force is too large, it is easy for the slag material to pass through the gauze holes, while if the extrusion force is too small, slag removal cannot be fully achieved;

[0006] The extrusion is uneven. For example, the sugar solution at the center position wrapped by the gauze is not easy to be extruded, and it cannot be solved by increasing the extrusion force;

[0007] It is not suitable for large-scale production. For sugar production enterprises with large-scale production, the gauze filtration method may not be able to meet the production requirements. Summary of the Invention

[0008] The purpose of the present invention is to provide a slag removal and clarification process based on the production of ancient method maltose to solve the problems that the traditional process is not suitable for large-scale operation and has poor slag removal effect.

[0009] To solve the above technical problems, the technical solution adopted by the present invention is:

[0010] As Figure 1 shown, the present invention provides a slag removal and clarification process based on the production of ancient method maltose, including the following steps:

[0011] S1: Dilute the fermented glutinous rice and malt mixture with water, and then add it to a crushing device to crush it into a paste with uniform particles.

[0012] The malt and glutinous rice mixture is pretreated by first crushing it, so that the mixture becomes a homogenized paste, and then filtered, so that the sugar solution can be fully filtered out, improving the separation effect of the sugar residue.

[0013] S2: Slowly and evenly pour the paste obtained in step S1 into a primary screening device. After screening, the sugar solution is obtained, and at the same time, the filter residue remains on the primary screening device.

[0014] S3: Put the filter residue in step S2 into a secondary screening device for secondary screening to filter out the residual sugar solution.

[0015] By setting two - stage screening, the primary screening is for initial screening and the secondary screening is for fine screening. On the one hand, the filtering effect is improved. On the other hand, the filtering process can be carried out simultaneously at multiple different precisions, thus improving the filtering efficiency.

[0016] S4: Let the obtained sugar solution stand and clarify until the precipitate is separated from the pure sugar solution.

[0017] A further improvement of the technical solution of the present invention lies in: The primary screening device includes a frame body. Inside the frame body, a support frame is fixedly connected. Between the inner sides of the support frame, a wheel seat is fixedly connected. The outside of the wheel seat is rotatably connected to a wheel frame. Between the inner sides of the wheel frame, a filter cylinder is fixedly connected. Between the inner sides of the wheel frame, a number of wing plates are fixedly connected. The wing plates are set as arc - shaped plates and are in contact with the filter cylinder. A through - groove is opened at the top of the wheel seat; at the bottom of the wheel seat, a blowing pipe is fixedly connected. A number of first nozzles are arranged on the outside of the blowing pipe. The blowing pipe is connected to an external air pump through a pipeline; at the bottom inside the frame body, a receiving box is placed. At the bottom of the wheel seat, a conduction pipe is provided, and the conduction pipe is communicated with the receiving box; The crushing device includes a crushing chamber fixedly connected inside the frame body. Inside the crushing chamber, there is a crushing component for crushing the glutinous rice and malt mixture. The crushing chamber is arranged above the wheel frame.

[0018] With the above technical solution, the fermentation mixture of malt and glutinous rice is first diluted and then added to a crushing device for crushing, so that the mixture becomes a uniform and homogenized paste. Then, the paste is poured onto a wheel frame (the outside of the wheel frame is divided into several independent filtering chambers by wing plates). The sugar solution passes through the filter cylinder and flows into the wheel seat through the through grooves, while the sugar residue remains outside the filter cylinder. The crushing bin is located above the wheel frame at a non-central position. As the filtering process progresses, the accumulation amount of sugar residue in the chambers formed by the wing plates gradually increases, causing the weight on one side of the wheel frame to increase. The weight of the part of the wheel frame carrying the sugar residue is greater than that of the other side of the wheel frame, resulting in the rotation of the wheel frame relative to the wheel seat, changing the area of the wheel frame facing the crushing bin. As the wheel frame rotates, the chamber formed by the wing plates with sugar residue rotates downward, thus pouring the sugar residue onto the secondary crushing device, realizing the automatic cleaning of the filter cylinder. The process does not require manual cleaning and dredging of the filter holes, ensuring the filtering effect and efficiency.

[0019] A further improvement of the technical solution of the present invention lies in that: the secondary screening device includes four transmission shafts rotatably connected between the inner sides of the support frame. On both sides of the outside of each transmission shaft, two synchronous pulleys are symmetrically and fixedly connected. The four synchronous pulleys on each side are connected by a synchronous belt; steel belts are fixedly connected to the outside of the synchronous belts. A screen is fixedly connected between the two synchronous belts close to each other. A feeding motor is fixedly connected to the top of the support frame. One end of one of the transmission shafts extends outside the support frame and is connected to the output end of the feeding motor through a belt and a pulley; a roller brush is rotatably connected between the inner sides of the support frame. A cleaning motor is fixedly connected to the top of the support frame. One end of the central shaft of the roller brush extends outside the support frame and is connected to the output end of the cleaning motor through a belt and a pulley; a spray pipe is fixedly connected inside the support frame. A number of second nozzles are arranged on the outside of the spray pipe. One end of the spray pipe is connected with a plug, and the other end is communicated with an external water supply device through a pipeline; a slag box is placed at the bottom of the frame body.

[0020] With the above technical solution, on the secondary screening device, the sugar residue falls on the screen, and the sugar solution passes through the screen holes on the screen and then falls into the receiving box. The remaining sugar residue is driven by the operation of the feeding motor to rotate the transmission shaft, and through the synchronous belt drive, the synchronous pulleys rotate synchronously. The screen moves along with the synchronous belt and sends the sugar residue to a position close to the upper synchronous pulley. The sugar residue falls downward under the action of gravity into the slag box.

[0021] A further improvement of the technical solution of the present invention lies in that: an internal gear ring is fixedly connected to the outer side wall of the wheel frame, a transmission gear is rotatably connected to the outer side wall of the wheel seat, the transmission gear is meshed with the internal gear ring, a piston cylinder is fixedly connected to the side of the wheel seat close to the transmission gear, a first piston plate is slidably connected between the inner walls of the piston cylinder, a linkage rod is fixedly connected to one side of the first piston plate, a square groove is formed at the mouth position of the piston cylinder, a transmission block is fixedly connected to the end of the linkage rod away from the first piston plate, the transmission block is slidably connected with the square groove, a transmission rod is fixedly connected to the end of the central axis of the transmission gear, the transmission rod penetrates through the transmission block and is slidably connected with the transmission block. As shown in the figure, a reciprocating spiral groove is formed on the outer wall of the transmission rod, a sliding bead is fixedly connected to the inside of the transmission block, the sliding bead is slidably connected with the reciprocating spiral groove, an air inlet pipe and an air outlet pipe are arranged on the piston cylinder, and one-way valves are arranged inside the air inlet pipe and the air outlet pipe; a speed reduction cylinder is fixedly connected to the outer side wall of the crushing chamber, a second piston plate is slidably connected between the inner walls of the speed reduction cylinder, a cross plate is fixedly connected between the inner walls of the speed reduction cylinder, a sliding rod is slidably connected to one side of the cross plate, a linkage plate is fixedly connected to one end of the sliding rod, the end of the sliding rod away from the linkage plate extends to the other side of the cross plate and is fixedly connected to the second piston plate, a spring is sleeved on the outside of the sliding rod and between the second piston plate and the cross plate, an exhaust pipe is arranged on the speed reduction cylinder, a regulating valve for regulating the air flow is arranged on the exhaust pipe, and the end of the air outlet pipe away from the piston cylinder communicates with the inside of the speed reduction cylinder.

[0022] By adopting the above technical solution, through the arrangement of the transmission gear and the internal gear ring, when the wheel frame rotates the wheel seat first, the transmission gear revolves relative to the internal gear ring. During this process, the transmission gear will rotate itself and drive the transmission rod to rotate. During this process, through the sliding cooperation of the reciprocating spiral groove and the sliding bead, the transmission block makes a reciprocating motion (the outer structure of the transmission block is set to fit the two opposite sides of the inner wall of the square groove, so that the transmission block will not rotate along with the transmission rod), and drives the first piston plate to make a piston motion through the linkage rod. Cooperating with the one-way valves in the air inlet pipe and the air outlet pipe, air is continuously pumped from the air inlet pipe and discharged from the air outlet pipe into the speed reduction cylinder. Due to the limitation of the diameter of the exhaust pipe, the air cannot be discharged quickly. The air pressure entering the speed reduction cylinder at the beginning will push the second piston plate to move and compress the spring until the second piston plate touches the limit ring. At this time, the second piston plate cannot move further. At this time, along with the piston motion of the first piston plate, air is continuously injected into the speed reduction cylinder, but due to the limitation of the diameter of the exhaust pipe, the moving speed of the first piston plate is limited. Further, the rotating speed of the wheel frame is limited, avoiding the problem that the too fast rotating speed of the wheel frame affects the filtering effect.

[0023] A further improvement of the technical solution of the present invention lies in that a current-limiting plate is rotatably connected between the inner walls of the crushing chamber. One end of the central axis of the current-limiting plate extends to the outside of the crushing chamber and is fixedly connected with a driven gear. The outer side wall of the crushing chamber is fixedly connected with a slide rail, and a rack is slidably connected to the outside of the slide rail. The rack is meshed with the driven gear, the rack is fixedly connected with a linkage plate, and two limiting rods for limiting the current-limiting plate are fixedly connected between the two sides of the inner wall of the crushing chamber.

[0024] By adopting the above technical solution, the discharging speed at the bottom of the crushing chamber is restricted by setting a current-limiting plate that can move synchronously with the rotation speed of the wheel frame, and the feeding speed of the crushing chamber to the primary crushing device can be automatically controlled according to the rotation speed of the wheel frame. Specifically, when the rotation speed of the wheel frame decreases, the blowing speed from the piston cylinder to the speed-reducing cylinder is slower, and when this speed is less than the exhaust speed of the exhaust pipe, the second piston plate does not move. When the rotation speed of the wheel frame increases so that the blowing speed from the piston cylinder to the speed-reducing cylinder is greater than the exhaust speed of the exhaust pipe, the second piston plate starts to move, and drives the linkage plate and the rack to move through the slide rod. The rack is meshed with the driven gear. Therefore, when the rack moves, it will drive the driven gear to rotate. Further, it will drive the current-limiting plate to flip, so that the discharging speed at the bottom of the crushing chamber increases.

[0025] A further improvement of the technical solution of the present invention lies in that two fixing plates are symmetrically and fixedly connected to the top of the support frame. Flow guide plates are fixedly connected to the sides of the fixing plates close to each other. A flattening rod is fixedly connected between the sides of the two flow guide plates close to each other, and the outer part of the flattening rod is in a corrugated structure.

[0026] By adopting the above technical solution, by setting the flattening rod, when the sugar pile passes through, it will be flattened and conveyed in a layout of multiple parallel strips. After the sugar pile is spread out, it passes through the sieve for filtering, so as to achieve uniform and comprehensive filtering. For the sugar residues at the edge parts, they are guided to the central area by the flow guide plates for flattening, thus avoiding the overflow of sugar residues.

[0027] A further improvement of the technical solution of the present invention lies in that the synchronous belt is in an isosceles trapezoid shape, and the length of the lower base of the synchronous belt is less than the length of the upper base. A flow guide cover is fixedly connected between the inner sides of the support frame, and the flow guide cover is in contact with the sieve.

[0028] With the above technical solution, every four synchronous wheels form a group and are jointly connected to a synchronous belt. The four synchronous wheels in the same group are distributed in an inverted isosceles trapezoid shape, making the synchronous belt and the sieve both form an inverted isosceles trapezoid shape. When the sugar residue passes through the side (the waist part of the isosceles trapezoid), the sugar residue is in an obliquely downward direction relative to the sieve, making it easier for the sugar residue to fall off into the residue box during the conveying process; and by setting a deflector, on the one hand, the sugar residue directly falling off the sieve falls on the deflector and falls into the residue box along with the deflector, avoiding a large amount of sugar residue falling on the roller brush and affecting the cleaning effect of the sieve; in addition, the deflector can also block the water flow sprayed by the second nozzle and the scoured sugar residue, preventing waste from splashing out.

[0029] A further improvement of the technical solution of the present invention is that: one side of the wheel seat is fixedly connected with a U-shaped frame, the inner side of the U-shaped frame is rotatably connected with a swing rod through a torsion spring, and one end of the swing rod away from the U-shaped frame is rotatably connected with a knocking block.

[0030] With the above technical solution, during the rotation of the wheel frame, although the first nozzle is provided to blow the sugar residue off the filter cylinder, there is a situation where some sugar residue adheres to the wing plate. Therefore, in this embodiment, a knocking block is also provided. When the wheel frame rotates, the wing plate squeezes the knocking block and drives the swing rod to flip. During the process, the torsion spring accumulates potential energy until the wing plate disengages from the knocking block. At this time, the swing rod rotates back to the next wing plate under the action of the torsion spring, and the knocking block knocks the wing plate, thereby "knocking off" the sugar residue adhering to the wing plate.

[0031] Due to the adoption of the above technical solution, the technical progress achieved by the present invention compared with the prior art is:

[0032] 1. The present invention provides a slag removal and clarification process based on the production of ancient method maltose. First, the fermentation mixture of malt and glutinous rice is diluted and then added to a crushing device for crushing, making the mixture become a uniform and homogenized paste. Then, the paste is poured onto the wheel frame (the outside of the wheel frame is divided into several independent filtering chambers by wing plates). The sugar liquid passes through the filter cylinder and flows into the wheel seat through the through slots, while the sugar residue remains outside the filter cylinder; the crushing chamber is located above the wheel frame at a non-central position. As the filtering process progresses, the accumulation amount of sugar residue in the chambers composed of wing plates gradually increases, making the weight on one side of the wheel frame increase. The weight of the part of the wheel frame carrying the sugar residue is greater than that of the other side of the wheel frame, resulting in the rotation of the wheel frame relative to the wheel seat, making the area of the wheel frame facing the crushing chamber change. As the wheel frame rotates, the chamber composed of wing plates with sugar residue rotates downward, so as to pour the sugar residue onto the secondary crushing device, thus realizing the automatic cleaning of the filter cylinder. The process does not require manual cleaning and dredging of the filter holes, ensuring the filtering effect and filtering efficiency.

[0033] 2. The present invention provides a slag removal and clarification process based on the production of ancient maltose. On the secondary screening device, the sugar slag falls on the screen, and the sugar liquid passes through the screen holes on the screen and then falls into the receiving box. The residual sugar slag is driven by the feeding motor to rotate the transmission shaft, and through the synchronous belt drive, each synchronous pulley rotates synchronously. The screen moves along with the synchronous belt and sends the sugar slag to a position close to the upper synchronous pulley. The sugar slag falls downward under the action of gravity into the slag box, thus realizing the automatic cleaning of the screen and improving the filtering effect.

[0034] 3. By setting a structure that can limit the rotation speed of the wheel frame, the present invention can transmit part of the power of the rotation of the wheel frame to the piston movement of the first piston plate and limit the air intake and exhaust flux of the piston cylinder. As a result, when the rotation speed of the wheel frame is too fast, the rotation speed is hindered by air pressure, and the rotation speed can be limited when the rotation speed of the wheel frame is relatively fast, avoiding the problem that the sugar slag is sent out before being completely filtered due to the too fast rotation speed of the wheel frame, thus affecting the filtering effect.

[0035] 4. By setting a flow-limiting plate that can move synchronously with the rotation speed of the wheel frame to limit the discharging speed at the bottom of the crushing bin, the present invention can automatically control the feeding speed of the crushing bin to the primary crushing device according to the rotation speed of the wheel frame. Specifically, when the rotation speed of the wheel frame decreases, the blowing speed from the piston cylinder to the slow-down cylinder is relatively slow, and when this speed is less than the exhaust speed of the exhaust pipe, the second piston plate does not move. When the rotation speed of the wheel frame increases so that the blowing speed from the piston cylinder to the slow-down cylinder is greater than the exhaust speed of the exhaust pipe, the second piston plate starts to move and drives the linkage plate and the rack to move through the slide rod. The rack meshes with the driven gear. Therefore, when the rack moves, it will drive the driven gear to rotate. Further, it will drive the flow-limiting plate to flip, thereby increasing the discharging speed at the bottom of the crushing bin.

[0036] 5. By setting a flattening rod, when the sugar pile passes by, it will be flattened and conveyed in a layout of multiple parallel strips. After the sugar pile is spread out, it passes through the screen for filtration, thus enabling uniform and comprehensive filtration. For the sugar slag at the edge part, it is guided to the central area by the diversion plate for flattening, thus avoiding the overflow of sugar slag. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0054] The present invention will be further described in detail below in conjunction with embodiments:

[0055] Embodiment 1

[0056] As Figure 1 shown, the present invention provides a slag removal and clarification process based on the production of ancient maltose, including the following steps:

[0057] S1: Dilute the fermented glutinous rice and malt mixture with water, and then add a crushing device to crush it into a homogeneous paste with uniform particles;

[0058] Since malt itself is rich in fiber, and the fibers are intertwined during extrusion, making it difficult to completely extrude the sugar solution during extrusion. Therefore, in this solution, the malt and glutinous rice mixture is first crushed for pretreatment, so that the mixture becomes a homogeneous paste, and then filtered, so that the sugar solution can be fully filtered out, improving the separation effect of sugar slag.

[0059] S2: Slowly and evenly pour the paste obtained in step S1 into a primary screening device, and obtain sugar solution through screening, while the filter residue remains on the primary screening device;

[0060] S3: Put the filter residue in step S2 into a secondary screening device for secondary screening to filter out the residual sugar solution;

[0061] By setting two-stage screening, the primary screening is for preliminary screening, and the secondary screening is for fine screening. On the one hand, the filtering effect is improved, and on the other hand, the filtering process can be carried out simultaneously at multiple different precisions, so as to improve the filtering efficiency.

[0062] S4: Let the obtained sugar solution stand and clarify until the precipitate is separated from the pure sugar solution.

[0063] Example 2

[0064] As Figure 4 , Figure 5 and Figure 6 shown, on the basis of Example 1, the present invention provides a technical solution: Preferably, the primary screening device includes a frame 1, a support frame 2 is fixedly connected inside the frame 1, a wheel seat 3 is fixedly connected between the inner sides of the support frame 2, a wheel frame 4 is rotatably connected to the outside of the wheel seat 3, a filter cylinder 50 is fixedly connected between the inner sides of the wheel frame 4, a plurality of wing plates 5 are fixedly connected between the inner sides of the wheel frame 4, the wing plates 5 are arranged as arc-shaped plates and are in contact with the filter cylinder 50, and a through groove is opened at the top of the wheel seat 3; a blowing pipe 8 is fixedly connected to the bottom of the wheel seat 3, a plurality of first nozzles 9 are arranged outside the blowing pipe 8, and the blowing pipe 8 is communicated with an external air pump through a pipeline; a receiving box 47 is placed at the bottom inside the frame 1, a conduction pipe 49 is arranged at the bottom of the wheel seat 3, and the conduction pipe 49 is communicated with the receiving box 47; the crushing device includes a crushing chamber 6 fixedly connected inside the frame 1, a crushing component for crushing the mixture of glutinous rice and malt is arranged inside the crushing chamber 6, and the crushing chamber 6 is arranged above the wheel frame 4.

[0065] Although the prior art proposes a method of using a filter screen for filtration to remove slag, sugar slag will accumulate in the filter holes during the filtration process, thus affecting the filtration effect and filtration efficiency. It is necessary to remove the sugar slag in real time;

[0066] In this embodiment, by first diluting the fermentation mixture of malt and glutinous rice and then adding it to the crushing device for crushing, the mixture becomes a uniform and homogenized paste, and then the paste is poured onto the wheel frame 4 (specifically, on the filter cylinder 50 inside the wheel frame 4. Among them, the outside of the filter cylinder 50 is divided into several independent filter chambers by the wing plates 5). The sugar solution passes through the filter cylinder 50 and flows into the wheel seat 3 through the through groove, while the sugar slag remains outside the filter cylinder 50; the crushing chamber 6 is located above the wheel frame 4 at a non-central position. As the sugar slag accumulates gradually in the chamber formed by the wing plates 5 during the filtration process, the weight on one side of the wheel frame 4 increases, and the weight of the part of the wheel frame 4 carrying the sugar slag is greater than that of the other side of the wheel frame 4, resulting in the rotation of the wheel frame 4 relative to the wheel seat 3, so that the area of the wheel frame 4 facing the crushing chamber 6 changes. As the wheel frame 4 rotates, the chamber formed by the wing plates 5 with sugar slag rotates downward, so as to pour the sugar slag onto the secondary crushing device, thus realizing the automatic cleaning of the filter cylinder 50. The process does not require manual cleaning and dredging of the filter holes, ensuring the filtration effect and filtration efficiency;

[0067] Among them, the first nozzle 9 is directly facing the filter cartridge 50 obliquely below, and by controlling the operation of the external air pump, air is supplied to the air blowing pipe 8 and blown out from the first nozzle 9 to blow away the sugar residue adhering to the outer wall of the filter cartridge 50, thereby avoiding the sugar residue adhering to the filter cartridge 50 and affecting subsequent filtration; the sugar liquid entering the wheel seat 3 flows into the material receiving box 47 through the conducting pipe 49.

[0068] like Figure 7 , Figure 8 and Figure 12 As shown, preferably, the secondary screening device includes four transmission shafts 29 rotatably connected between the inner sides of the support frame 2, two synchronous wheels 30 are symmetrically fixedly connected to the two sides of the outside of each transmission shaft 29, and the four synchronous wheels 30 on each side are connected through a synchronous belt 31; the outside of the synchronous belt 31 is fixedly connected to a steel belt 32, and a screen 33 is fixedly connected between the sides where the two synchronous belts 31 are close to each other. A feeding motor 39 is fixedly connected to the top of the support frame 2, and one end of one of the transmission shafts 29 extends to the outside of the support frame 2 and is connected to the feeding motor 3 The output end of 9 is connected to the pulley through a belt; a roller brush 36 is rotatably connected between the inner sides of the support frame 2, a cleaning motor 38 is fixedly connected to the top of the support frame 2, one end of the central axis of the roller brush 36 extends to the outside of the support frame 2 and is connected to the output end of the cleaning motor 38 through a belt and pulley; a nozzle 34 is fixedly connected to the inside of the support frame 2, a plurality of second nozzles 35 are arranged on the outside of the nozzle 34, one end of the nozzle 34 is connected to a plug, and the other end is connected to an external water supply device through a pipeline; a slag box 48 is placed at the bottom of the frame 1.

[0069] In this embodiment, on the secondary screening device, the sugar residue falls on the screen 33, and the sugar liquid falls into the receiving box 47 after passing through the sieve holes on the screen 33, while the residual sugar residue is driven by the feeding motor 39 to drive the transmission shaft 29 to rotate, and the synchronous belt 31 is used to drive the synchronous wheels 30 to rotate synchronously. The screen 33 moves along with the synchronous belt 31 and sends the sugar residue to a position close to the upper synchronous wheel 30, and the sugar residue falls downward to the residue box 48 under the action of gravity.

[0070] Among them, there is some sugar residue adhering to the screen 33, and the roller brush 36 is driven to rotate by the cleaning motor 38. The roller brush 36 is provided with bristles on the outside, and the screen 33 can be cleaned during the rotation process. At the same time, water is supplied to the nozzle 34 through an external water supply device, and water is sprayed from the second nozzle 35 onto the screen 33, thereby washing away the sugar residue on the screen 33, reducing the influence of the sugar residue adhering to the screen 33 on subsequent filtration.

[0071] Example 3

[0072] like Figure 3 , Figure 9 and Figure 13As shown, on the basis of Embodiment 2, the present invention provides a technical solution: Preferably, an internal gear ring 11 is fixedly connected to the outer side wall of the wheel carrier 4, a transmission gear 10 is rotatably connected to the outer side wall of the wheel seat 3, the transmission gear 10 is meshed with the internal gear ring 11, a piston cylinder 7 is fixedly connected to one side of the wheel seat 3 close to the transmission gear 10, a first piston plate 15 is slidably connected between the inner walls of the piston cylinder 7, a linkage rod 14 is fixedly connected to one side of the first piston plate 15, a square groove 53 is formed at the mouth position of the piston cylinder 7, a transmission block 52 is fixedly connected to the end of the linkage rod 14 away from the first piston plate 15, the transmission block 52 is slidably connected with the square groove 53, a transmission rod 51 is fixedly connected to the end of the central axis of the transmission gear 10, the transmission rod 51 penetrates through the transmission block 52 and is slidably connected with the transmission block 52, as Figure 14 shown, a reciprocating spiral groove 12 is formed on the outer wall of the transmission rod 51, a sliding bead 13 is fixedly connected to the inside of the transmission block 52, the sliding bead 13 is slidably connected with the reciprocating spiral groove 12, an air inlet pipe 17 and an air outlet pipe 16 are arranged on the piston cylinder 7, and one-way valves are arranged inside the air inlet pipe 17 and the air outlet pipe 16; a speed reducing cylinder 18 is fixedly connected to the outer side wall of the crushing chamber 6, a second piston plate 54 is slidably connected between the inner walls of the speed reducing cylinder 18, a cross plate 22 is fixedly connected between the inner walls of the speed reducing cylinder 18, a sliding rod 23 is slidably connected to one side of the cross plate 22, a linkage plate 25 is fixedly connected to one end of the sliding rod 23, the end of the sliding rod 23 away from the linkage plate 25 extends to the other side of the cross plate 22 and is fixedly connected to the second piston plate 54, a spring 24 is sleeved on the outside of the sliding rod 23 and between the second piston plate 54 and the cross plate 22, an exhaust pipe 26 is arranged on the speed reducing cylinder 18, a regulating valve 27 for regulating the air flow rate is arranged on the exhaust pipe 26, and the end of the air outlet pipe 16 away from the piston cylinder 7 communicates with the inside of the speed reducing cylinder 18.

[0073] Among them, when the first piston plate 15 moves toward the side close to the transmission rod 51, the one-way valve in the air inlet pipe 17 is turned on, and the one-way valve in the air outlet pipe 16 is blocked. At this time, the piston cylinder 7 extracts external air through the air inlet pipe 17; when the first piston plate 15 moves toward the side away from the transmission rod 51, the one-way valve in the air inlet pipe 17 is blocked, and the one-way valve in the air outlet pipe 16 is turned on. At this time, the piston cylinder 7 blows air into the inside of the speed reducing cylinder 18 through the air outlet pipe 16.

[0074] In the primary screening device, since it is necessary to drive the rotation of the wheel carrier 4 by means of the weight of the sugar residue screened out by the primary filter, and the rotation speed of the wheel carrier 4 is positively correlated with the accumulated mass of the sugar residue on the filter cylinder 50, when there is a large amount of sugar residue on the wheel carrier 4, the wheel carrier 4 will rotate rapidly, and the mixture will quickly turn downward after falling on the wheel carrier 4, so that the filter cylinder 50 cannot fully filter and pour out the sugar residue, thus affecting the filtration modification; in addition, when the rotation speed is too fast, there is also a problem of throwing out the mixture. Therefore, it is necessary to limit the rotation speed of the wheel carrier 4;

[0075] In this embodiment, by providing a transmission gear 10 and an internal gear ring 11, when the wheel carrier 4 rotates relative to the wheel seat 3 first, the transmission gear 10 revolves relative to the internal gear ring 11. During this process, the transmission gear 10 will rotate on its own axis and drive the transmission rod 51 to rotate. During this process, the reciprocating spiral groove 12 and the sliding bead 13 are in sliding fit, causing the transmission block 52 to perform a reciprocating motion (the outer part of the transmission block 52 is configured to fit against the two opposite inner walls of the square groove 53, so that the transmission block 52 will not rotate along with the transmission rod 51), and the first piston plate 15 is driven to perform a piston motion through the linkage rod 14. Cooperating with the check valves in the air inlet pipe 17 and the air outlet pipe 16, air is continuously drawn from the air inlet pipe 17 and discharged into the retardation cylinder 18 through the air outlet pipe 16. Due to the diameter limitation of the exhaust pipe 26, the air cannot be quickly discharged. The air pressure initially entering the retardation cylinder 18 will push the second piston plate 54 to move and compress the spring 24 until the second piston plate 54 contacts the limit ring. At this time, the second piston plate 54 cannot move further. At this time, along with the piston motion of the first piston plate 15, air continues to be injected into the retardation cylinder 18, but due to the diameter limitation of the exhaust pipe 26, the moving speed of the first piston plate 15 is restricted. Further, the rotating speed of the wheel carrier 4 is restricted, avoiding the problem that the too-fast rotating speed of the wheel carrier 4 affects the filtering effect.

[0076] Embodiment 4

[0077] As Figure 3 、 Figure 9 and Figure 13 shown, on the basis of Embodiment 3, the present invention provides a technical solution: Preferably, a flow limiting plate 19 is rotatably connected between the inner walls of the crushing chamber 6. One end of the central axis of the flow limiting plate 19 extends to the outside of the crushing chamber 6 and is fixedly connected with a driven gear 20. The outer side wall of the crushing chamber 6 is fixedly connected with a slide rail 46. A rack 21 is slidably connected to the outside of the slide rail 46. The rack 21 is meshed with the driven gear 20. The rack 21 is fixedly connected with a linkage plate 25. Two limiting rods 28 for limiting the flow limiting plate 19 are fixedly connected between the two sides of the inner wall of the crushing chamber 6.

[0078] In order to avoid the situation that the filter cartridge 50 "has no time to filter" due to the too-fast rotation of the wheel carrier 4, a design for limiting the speed of the wheel carrier 4 is adopted in the above-mentioned embodiment. Therefore, the feeding speed from the crushing chamber 6 to the primary crushing device should be restricted. The reason is that: initially, the rotation speed of the wheel carrier 4 is slow. If the feeding speed from the crushing chamber 6 to the primary crushing device is too fast, it is easy to cause blockage and overflow at the discharging part of the crushing chamber 6. Therefore, it is necessary to limit the discharging speed at the bottom of the crushing chamber 6; but after the discharging speed is restricted, when the rotation speed of the wheel carrier 4 increases, there will be a situation of insufficient feeding, making the filtering speed always affected by the speed-limiting structure at the bottom of the crushing chamber 6, thus affecting the filtering efficiency;

[0079] In this embodiment, by providing a current-limiting plate 19 that can move synchronously with the rotation speed of the wheel frame 4 to limit the discharging speed at the bottom of the crushing chamber 6, the feeding speed of the crushing chamber 6 to the primary crushing device can be automatically controlled according to the rotation speed of the wheel frame 4. Specifically, when the rotation speed of the wheel frame 4 decreases, the blowing speed from the piston cylinder 7 to the retardation cylinder 18 is slow, and when this speed is less than the exhaust speed of the exhaust pipe 26, the second piston plate 54 does not move. When the rotation speed of the wheel frame 4 increases such that the blowing speed from the piston cylinder 7 to the retardation cylinder 18 is greater than the exhaust speed of the exhaust pipe 26, the second piston plate 54 starts to move, and drives the linkage plate 25 and the rack 21 to move through the slide rod 23. The rack 21 meshes with the driven gear 20. Therefore, when the rack 21 moves, it drives the driven gear 20 to rotate. Further, it drives the current-limiting plate 19 to flip, thereby increasing the discharging speed at the bottom of the crushing chamber 6.

[0080] Embodiment 5

[0081] As Figure 7 and Figure 12 As shown in the figure, on the basis of Embodiment 4, the present invention provides a technical solution: Preferably, two fixing plates 40 are symmetrically and fixedly connected to the top of the support frame 2. Flow guide plates 41 are fixedly connected to the sides of the fixing plates 40 close to each other. A flattening rod 42 is fixedly connected between the sides of the two flow guide plates 41 close to each other. The outer part of the flattening rod 42 has a corrugated structure.

[0082] Since the sugar residues filtered out after the first filtration need to fall onto the screen 33 for further filtration, and the above process is that the wheel frame 4 flips to "dump" the sugar residues onto the screen 33, the sugar residues usually fall in a pile. And the sugar pile on the screen 33 cannot be evenly filtered, thus affecting the filtration effect.

[0083] In this embodiment, by providing the flattening rod 42, when the sugar pile passes through, it will be flattened and conveyed in a layout of multiple parallel strips. After the sugar pile is spread out, it passes through the screen 33 for filtration, so as to achieve uniform and comprehensive filtration. For the sugar residues at the edge parts, they are guided by the flow guide plate 41 to the central area for flattening, thus preventing the sugar residues from overflowing.

[0084] As Figure 8 and Figure 15 As shown in the figure, preferably, the synchronous belt 31 is in an isosceles trapezoid shape, and the length of the lower base of the synchronous belt 31 is less than the length of the upper base. A flow guide cover 37 is fixedly connected between the inner sides of the support frame 2, and the flow guide cover 37 is in contact with the screen 33.

[0085] In this embodiment, every four synchronous pulleys 30 form a group and are jointly connected to a synchronous belt 31. The four synchronous pulleys 30 in the same group are distributed in an inverted isosceles trapezoid shape, so that both the synchronous belt 31 and the screen 33 form an inverted isosceles trapezoid shape. When the sugar residue passes through the side (the waist part of the isosceles trapezoid), the sugar residue is in an obliquely downward direction relative to the screen 33, making it easier to fall off into the residue box 48 during the conveying process. By setting the flow guide cover 37, on the one hand, the sugar residue directly falling off the screen 33 falls on the flow guide cover 37 and falls into the residue box 48 along with the flow guide cover 37, avoiding a large amount of sugar residue falling on the roller brush 36 and affecting the cleaning effect of the screen 33. In addition, the flow guide cover 37 can also block the water flow sprayed by the second nozzle 35 and the sugar residue washed out, preventing the waste from splashing out.

[0086] As Figure 10 and Figure 12 shown, preferably, one side of the wheel seat 3 is fixedly connected with a U-shaped frame 43. The inner side of the U-shaped frame 43 is rotatably connected with a swing rod 44 through a torsion spring. One end of the swing rod 44 away from the U-shaped frame 43 is rotatably connected with a knocking block 45.

[0087] In this embodiment, during the rotation of the wheel frame 4, although the first nozzle 9 is provided to blow the sugar residue off the filter cylinder 50, there is still a situation where some sugar residue adheres to the wing plate 5. Therefore, in this embodiment, a knocking block 45 is also provided. When the wheel frame 4 rotates, the wing plate 5 squeezes the knocking block 45 and drives the swing rod 44 to flip. During this process, the torsion spring accumulates potential energy until the wing plate 5 disengages from the knocking block 45. At this time, the swing rod 44 rotates back to the next wing plate 5 under the action of the torsion spring, and the knocking block 45 knocks the wing plate 5, thereby "knocking off" the sugar residue adhering to the wing plate 5.

[0088] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
