Description

Technical Field

[0001] The present invention relates to the technical field of membrane separation, and particularly relates to a separation and purification device for malt syrup saccharification liquid and its purification process. Background Art

[0002] In the production process of malt syrup, the separation and purification of the saccharification liquid is a crucial link. The saccharification liquid not only contains the target product malt syrup but also is mixed with various impurities, such as incompletely saccharified starch granules, proteins, colloidal substances, and microorganisms. If these impurities are not effectively removed, they will seriously affect the quality of malt syrup, reducing its purity and sweetness. Currently, in the technical field of separation and purification of malt syrup saccharification liquid, the mainstream process mainly relies on installing a filter membrane in the separation tank to achieve the separation and filtration operation of the saccharification liquid. The filter membrane can effectively intercept the impurities in the saccharification liquid. However, this technology has significant drawbacks. During the long-term use of the filter membrane, the filtration performance will decline due to the continuous accumulation of impurities. To ensure the separation effect, the filter membrane needs to be replaced regularly. However, during the filter membrane replacement period, the entire separation work has to be suspended, which will undoubtedly interrupt the production process and seriously affect the processing efficiency of malt syrup. Frequent shutdowns for filter membrane replacement not only consume human and material resources but also greatly limit the continuity and efficiency of production. Therefore, a separation and purification device for malt syrup saccharification liquid and its purification process are proposed to facilitate the replacement of the filter membrane and ensure the continuity of the saccharification liquid separation work.

Detailed implementation manners

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0018] In order to facilitate the replacement of the filter membrane and at the same time ensure the continuity of the saccharified liquid separation work, as an embodiment of the present invention, as shown in Figure 1 , Figure 2 , Figure 3As shown in the figure, a malt syrup saccharification liquid separation and purification device of the present invention includes a separation tank 1. A coarse filtration component is provided at the upper part inside the separation tank 1. A horizontally arranged shunt baffle 2 is fixedly connected to the middle of the separation tank 1. A plurality of groups of piston-type extrusion liquid supply components distributed in a circle are slidably connected to the shunt baffle 2. A driving structure for driving the piston-type extrusion liquid supply components to work is connected to the top of the separation tank 1. The lower part of the piston-type extrusion liquid supply component is connected to a liquid collection cylinder 4 through a membrane filter 3.

[0019] During use, in the process of separating and purifying the malt syrup saccharification liquid, first, the saccharification liquid is conveyed to the separation tank 1. After the saccharification liquid enters the separation tank 1, it is preliminarily filtered by the coarse filtration component. The coarse filtration component can effectively intercept larger impurities such as incompletely saccharified starch particles in the saccharification liquid, realizing the preliminary purification of the saccharification liquid, reducing the filtration burden of the subsequent membrane filter 3. The saccharification liquid that has passed through the coarse filtration smoothly passes through the coarse filtration component and flows downward to the shunt baffle 2. The saccharification liquid falling on the shunt baffle 2 will enter several groups of piston-type extrusion liquid supply components respectively. At this time, the driving structure at the top of the separation tank 1 drives the piston-type extrusion liquid supply components to work. When the lower end of the piston-type extrusion liquid supply component is connected to the membrane filter 3, the membrane filter 3 can provide support for the piston-type extrusion liquid supply component, so as to ensure the stability of the piston-type extrusion liquid supply component when it is extruded; under the extrusion action of the piston-type extrusion liquid supply component, the saccharification liquid is extruded into the membrane filter 3. The membrane filter 3 filters the saccharification liquid more finely, and can intercept tiny impurities such as proteins, colloidal substances, and microorganisms, thereby realizing the deep purification of the saccharification liquid. The purified malt syrup after passing through the membrane filter 3 flows into the liquid collection cylinder 4 for collection, and thus the separation of the saccharification liquid is completed; by supplying liquid to the membrane filter 3 through the piston-type extrusion liquid supply component for filtration, it can ensure that the liquid supply work of all piston-type extrusion liquid supply components is independent of each other. An appropriate number of piston-type extrusion liquid supply components can be set according to needs, and it also avoids affecting the work of other piston-type extrusion liquid supply components when the piston-type extrusion liquid supply component is maintained and replaced. During the operation of the device, if a certain membrane filter 3 needs to be replaced, in order to ensure the normal operation of other groups of piston-type extrusion liquid supply components, first close the corresponding piston-type extrusion liquid supply component to prevent the liquid from continuing to enter the membrane filter 3 connected to the piston-type extrusion liquid supply component, and then remove the membrane filter 3. After removing the membrane filter 3, the piston-type extrusion liquid supply component loses support and can slide up and down. At this time, the driving structure drives several groups of piston-type extrusion liquid supply components to work. Since there is liquid in this group of piston-type extrusion liquid supply components, under the action of gravity and the driving structure, this group of piston-type extrusion liquid supply components will move downward and remain in a sliding connection state with the shunt baffle 2, while the other multiple groups of piston-type extrusion liquid supply components are not affected and can carry out normal filtration work, thus ensuring the continuity of the saccharification liquid separation work. When the driving structure drives the set of piston - type extrusion liquid - supply components to reset and move upward, connect the upper end of the new membrane filter 3 to the set of piston - type extrusion liquid - supply components and the lower end to the liquid - collecting cylinder 4. After the connection is completed, the membrane filter 3 provides support for the piston - type extrusion liquid - supply components. Then, open the liquid - inlet channel of the set of piston - type extrusion liquid - supply components. At this time, the liquid on the shunt baffle 2 will enter the newly installed membrane filter 3 under the extrusion of the piston - type extrusion liquid - supply components, successfully completing the replacement operation of the membrane filter 3. This replacement method not only improves the convenience of replacing the membrane filter 3 but also ensures the continuous progress of the saccharified liquid separation work during the replacement process.

[0020] To improve the filtration efficiency, exemplarily, as Figure 3 、 Figure 5 、 Figure 8 、 Figure 9 shown, the present invention further includes that the piston - type extrusion liquid - supply components include a plurality of groups of sliding holes 5 circumferentially distributed on the shunt baffle 2. A piston cylinder 6 is slidably connected in the sliding hole 5. A piston plate 7 is hermetically and slidably connected in the piston cylinder 6. The upper surface of the piston plate 7 is fixedly connected with a movable tube 8. The inner side of the upper end of the movable tube 8 is slidably connected with a positioning slide bar 9 fixedly connected with the coarse - filtration component. A return spring 10 is fixedly connected between the positioning slide bar 9 and the piston plate 7. One side of the upper part of the piston cylinder 6 is provided with a feed liquid port 11 communicating with the inside of the piston cylinder 6. A fixed rod 12 is fixedly connected to the side of the movable tube 8. An extrusion roller 13 is rotatably connected to the fixed rod 12. The extrusion roller 13 is in extrusion contact with the driving structure.

[0021] During use, the malt syrup saccharified liquid is transported into the separation tank 1 through the feed port of the separation tank 1. The saccharified liquid first passes through the coarse - filtration component for preliminary filtration to remove large - particle impurities and then flows into the area of the shunt baffle 2. At this time, the piston - type extrusion liquid - supply components are in the initial position. The piston plate 7 is located above the piston cylinder 6 under the action of the return spring 10, and the piston cylinder 6 is not yet filled with liquid. The saccharified liquid flows into the piston cylinder 6 through the feed liquid port 11 on one side of the upper part of the piston cylinder 6. Start the driving structure. The driving structure starts to operate and is in extrusion contact with the extrusion roller 13. As the driving structure moves, the extrusion roller 13 is extruded, driving the movable tube 8 and the piston plate 7 to slide downward in the piston cylinder 6. When the piston plate 7 slides downward, it exerts an extrusion effect on the saccharified liquid in the piston cylinder 6. During the extrusion process, the positioning slide bar 9 plays a guiding role to ensure that the movable tube 8 and the piston plate 7 move in a straight line. The saccharified liquid in the piston cylinder 6 is finely filtered through the membrane filter 3 connected to the lower part of the piston cylinder 6 under the action of pressure. Through the extrusion action of the piston plate 7, the saccharified liquid can fully pass through the membrane filter 3, improving the filtration efficiency. When the extrusion action of the driving structure is completed and the contact with the extrusion roller 13 is lost, the reset spring 10 takes effect, pushing the piston plate 7 and the movable tube 8 to reset upward. During the reset process, negative pressure is formed in the piston cylinder 6, and the coarsely filtered saccharification liquid is sucked in again through the feed liquid port 11 to prepare for the next extrusion liquid supply. This cycle is repeated to achieve continuous extrusion liquid supply and filtration purification of the maltose syrup saccharification liquid. The membrane filter 3 should be equipped with a one-way valve to prevent the liquid in the membrane filter 3 from flowing back and ensure the stable operation of the membrane filter 3 .

[0022] In order to ensure the separation and purification process of saccharified liquid and further improve the overall production efficiency, for example, Figure 1 , Figure 3 , Figure 8 , Figure 9 As shown, the present invention also includes that the driving structure includes a driving motor 14 arranged on the top of the separation tank 1, and the lower end of the output shaft 15 of the driving motor 14 is detachably connected to a horizontally arranged conical guide plate 16 through a clamping assembly, and a plurality of groups of radially arranged slide grooves 17 are distributed circumferentially on the conical guide plate 16, and a slider 18 is slidably connected in the slide groove 17, and an arc-shaped extrusion plate 19 is fixedly connected to the lower surface of the slider 18, and a wedge-shaped guide surface 20 is provided at the lower part of the arc-shaped extrusion plate 19, and the wedge-shaped guide surface 20 is in extrusion contact with the extrusion roller 13.

[0023] When in use, during the separation and purification process of the maltose syrup saccharified liquid, the saccharified liquid flows into the piston cylinder 6 through the feed liquid inlet 11 on one side of the upper part of the piston cylinder 6. At this time, the drive motor 14 is started to drive the conical guide plate 16 to start rotating. During the rotation of the conical guide plate 16, the arc extrusion plate 19 also moves synchronously. The wedge-shaped guide surface 20 at the lower part of the arc extrusion plate 19 is in extrusion contact with the extrusion roller 13 on the piston type extrusion liquid supply assembly. As the conical guide plate 16 continues to rotate, the wedge-shaped guide surface 20 of the arc extrusion plate 19 continuously squeezes the extrusion roller 13, thereby driving the extrusion roller 13 to drive the movable tube 8 and the piston plate 7 to slide downward in the piston cylinder 6. The movement of the piston plate 7 applies an extrusion force to the saccharified liquid in the piston cylinder 6, and pushes the saccharified liquid to be filtered through the membrane filter 3, thereby improving the filtration efficiency. When the amount of saccharified liquid in the separation tank 1 increases, in order to ensure efficient and stable operation of the equipment, the speed of the driving motor 14 needs to be increased accordingly. After the speed of the driving motor 14 is increased, the conical guide plate 16 is driven to rotate faster, and the movement speed of the slider 18 and the arc-shaped extrusion plate 19 connected to the conical guide plate 16 is greatly accelerated, thereby increasing the extrusion frequency between the wedge-shaped guide surface 20 and the extrusion roller 13, so that the extrusion efficiency can be matched with the amount of liquid inlet, effectively accelerating the filtration speed, and ensuring that the saccharified liquid can be processed in time; Moreover, as the rotational speed of the output shaft 15 of the drive motor 14 continues to climb, under the action of centrifugal force, the slider 18 begins to slide radially outward along the chute 17 on the conical guide plate 16. When the slider 18 moves outward along the conical surface of the conical guide plate 16, the height of the slider 18 decreases, thereby driving the arc-shaped extrusion plate 19 to move downward when moving outward. After the arc-shaped extrusion plate 19 moves downward, the extrusion position of the lower wedge-shaped guide surface 20 and the extrusion roller 13 also changes accordingly. At this time, the amplitude of the up and down movement of the arc-shaped extrusion driving the extrusion roller 13 increases, thereby increasing the movement range of the piston plate 7 in the piston cylinder 6. More saccharified liquid can be discharged during each extrusion, thereby further increasing the liquid supply volume of a single extrusion, effectively avoiding the problem of liquid accumulation caused by excessive liquid inflow, ensuring the progress of the saccharified liquid separation and purification process, and improving the overall production efficiency.

[0024] For the convenience of adjusting the position of the arc-shaped extrusion plate 19, exemplarily, as Figure 8 , Figure 9 shown, the present invention further includes that the clamping assembly includes a sliding ring 21 arranged at the center of the conical guide plate 16. The output shaft 15 of the drive motor 14 passes through the sliding ring 21. A positioning hole 22 is arranged on the side surface of the sliding ring 21, and a plurality of groups of vertically distributed pin holes 23 are arranged on the output shaft 15. The positioning hole 22 is threadedly connected with the pin hole 23 through a positioning bolt 24.

[0025] During use, when the actual liquid inflow increases and the filtration efficiency requirement improves, the position of the arc-shaped extrusion plate 19 can be adjusted to prompt the piston plate 7 to move downward by a larger amplitude, so that the amount of saccharified liquid flowing into the membrane filter 3 increases to meet higher filtration requirements; conversely, if the liquid inflow decreases or the filtration efficiency requirement decreases, the position of the arc-shaped extrusion plate 19 is appropriately adjusted to reduce the up and down movement range of the extrusion roller 13 when being extruded, and the downward movement amplitude of the piston plate 7 will also be correspondingly reduced to avoid energy waste or equipment loss caused by excessive extrusion; Adjusting the position of the arc-shaped extrusion plate 19 can also be achieved by adjusting the position of the sliding ring 21 on the output shaft 15 of the drive motor 14. First, loosen the positioning bolt 24 to enable the sliding ring 21 to freely slide on the output shaft 15. According to the actual situation, move the sliding ring 21 to a suitable position. After the sliding ring 21 reaches the predetermined position, select a suitable positioning bolt 24, accurately pass it through the positioning hole 22 on the side surface of the sliding ring 21, and threadedly connect it with the corresponding pin hole 23 on the output shaft 15. Finally, tighten the positioning bolt 24 to achieve precise adjustment of the position of the arc-shaped extrusion plate 19 and ensure the stable and efficient progress of the filtration process of the malt syrup saccharified liquid.

[0026] To improve the convenience of replacing the membrane filter 3, exemplarily, as Figure 6 , Figure 7As shown in the figure, the present invention further includes that several groups of arc-shaped rotating plates 25 distributed circumferentially are arranged on the outer side of the lower end of the piston cylinder 6, several groups of limiting plates 26 corresponding to the arc-shaped rotating plates 25 are distributed circumferentially on the lower surface of the flow dividing baffle 2, a rotating groove 27 is arranged on one side of the limiting plate 26 close to the arc-shaped rotating plate 25, and the arc-shaped rotating plate 25 is located in the rotating groove 27 and is slidably connected with the rotating groove 27.

[0027] During use, when a membrane filter 3 connected to a certain piston-type extrusion liquid supply component needs to be replaced, first close the liquid inlet channel corresponding to this component to prevent liquid from continuing to enter the membrane filter 3. Then remove the membrane filter 3. At this time, rotate the piston cylinder 6. Since the arc-shaped rotating plate 25 is slidably connected with the rotating groove 27, after the piston cylinder 6 rotates to a suitable position, the piston-type extrusion liquid supply component resumes the slidable connection state with the flow dividing baffle 2. Under the subsequent action of gravity and the driving structure, the piston cylinder 6 moves downward and maintains the slidable connection with the flow dividing baffle 2 to ensure the normal operation of other components. When a new membrane filter 3 is installed, rotate the piston cylinder 6 again, connect the upper end of the new membrane filter 3 to the piston cylinder 6, and the lower end to the liquid collecting cylinder 4. After the connection is completed, rotate the piston cylinder 6 and limit it so that it no longer has a slidable connection with the flow dividing baffle 2. Then open the liquid inlet channel to resume the filtering work of this component; Through the sliding connection structure of the arc-shaped rotating plate 25 and the rotating groove 27, the piston cylinder 6 can rotate flexibly during the replacement process of the membrane filter 3. When removing and installing the membrane filter 3, the position of the piston cylinder 6 can be conveniently adjusted without complex disassembly and repositioning operations, improving the convenience of replacing the membrane filter 3, reducing the time and labor costs required for replacement, and at the same time not affecting the normal operation of other piston-type extrusion liquid supply components, ensuring the continuity of the saccharified liquid separation work, avoiding the interruption of the entire production process due to the replacement of a single membrane filter 3, and improving the production efficiency.

[0028] Exemplarily, as Figure 3 、 Figure 6 、 Figure 7 shown in the figure, the present invention further includes that a ferrule type quick connection ball valve 28 is installed on the lower surface of the piston cylinder 6. The ferrule type quick connection ball valve 28 is communicated with the inside of the piston cylinder 6, and the ferrule type quick connection ball valve 28 is detachably connected to the upper end of the membrane filter 3.

[0029] During use, align the upper end of the membrane filter 3 with the ferrule type quick connection ball valve 28 on the lower surface of the piston cylinder 6. Through the quick connection structure of the ferrule type quick connection ball valve 28, a smooth liquid channel is formed between the inside of the piston cylinder 6 and the membrane filter 3 to ensure that the preliminarily filtered malt syrup saccharified liquid can smoothly flow into the membrane filter 3; Once the membrane filter 3 needs to be replaced, first close the ferrule quick - fitting ball valve 28 to cut off the liquid passage between the piston cylinder 6 and the membrane filter 3, preventing the saccharified liquid from continuing to flow into the old membrane filter 3. Subsequently, utilize the detachable feature of the ferrule quick - fitting ball valve 28 to remove the old membrane filter 3 from the ferrule quick - fitting ball valve 28. When installing a new membrane filter 3 later, connect its upper end to the ferrule quick - fitting ball valve 28 again and ensure a firm connection. Finally, open the ferrule quick - fitting ball valve 28 to put the new membrane filter 3 into use and continue the filtration work of the saccharified liquid.

[0030] Exemplarily, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that a plurality of groups of threaded installation pipes 29 communicating with the liquid collection cylinder 4 are flange - connected to the upper surface of the liquid collection cylinder 4. A nut 30 is thread - connected to the outside of the threaded installation pipe 29, and the lower end of the membrane filter 3 is detachably connected to the threaded installation pipe 29; A drain pipe 31 communicates with the lower surface of the liquid collection cylinder 4. A plurality of groups of legs 32 are provided on the lower surface of the liquid collection cylinder 4. An overhaul structure is connected between the liquid collection cylinder 4 and the shunt baffle 2.

[0031] During use, the malt syrup saccharified liquid that has been finely filtered by the membrane filter 3 will smoothly flow into the liquid collection cylinder 4 through the threaded installation pipe 29. Inside the liquid collection cylinder 4, the saccharified liquid gradually gathers and is then discharged through the drain pipe 31 for subsequent processing.

[0032] To facilitate the preliminary filtration of the saccharified liquid, exemplarily, such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 As shown, the present invention further includes that the coarse - filter assembly includes a connecting plate 33 fixedly connected to the inner wall of the separation tank 1. A plurality of groups of fan - shaped grooves 34 penetrating through are provided on the connecting plate 33. A fan - shaped filter plate 35 corresponding to the fan - shaped grooves 34 is detachably connected to the upper surface of the connecting plate 33. A plurality of groups of stirring rods 36 distributed in a circular pattern are fixedly connected to the upper - side surface of the upper part of the output shaft 15; The upper end of the positioning slide rod 9 is fixedly connected to the lower surface of the connecting plate 33; the conical guide plate 16 is provided with communication holes 37; a liquid inlet pipe 38 communicates with one side of the upper part of the separation tank 1.

[0033] During use, the malt syrup saccharification liquid flows into the separation tank 1 from the liquid inlet pipe 38. During the inflow process, the driving motor 14 drives the output shaft 15 to rotate, and the stirring rod 36 on the output shaft 15 rotates accordingly to stir the saccharification liquid that has just entered the separation tank 1. Stirring can make the saccharification liquid more evenly distributed, preventing local high concentration or impurity aggregation of the saccharification liquid. Under the stirring action, the saccharification liquid flows towards the sector filter plate 35. The saccharification liquid passes through the sector grooves 34 on the sector filter plate 35 to achieve preliminary filtration. Large particle impurities are intercepted on the sector filter plate 35, realizing the preliminary purification of the saccharification liquid, reducing the burden on the subsequent fine filtration of the membrane filter 3, and ensuring the quality of the final malt syrup product; The saccharification liquid that has passed through the coarse filtration component smoothly passes through the sector grooves 34 and flows downward. During this process, part of the saccharification liquid will fall on the conical guide plate 16. The communication holes 37 distributed on the conical guide plate 16 facilitate the continuous downward flow of the liquid, and finally fall on the diversion baffle 2. Subsequently, the saccharification liquid enters the subsequent piston-type extrusion liquid supply component along the trend, preparing for further fine filtration treatment.

[0034] Exemplarily, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 As shown in, the present invention further includes a maintenance structure including a plurality of groups of support rods 39 connected between the diversion baffle 2 and the liquid collection cylinder 4. One side of the support rod 39 is provided with a plurality of groups of bolt mounting holes 40, and an arc-shaped maintenance plate 41 is arranged outside the support rod 39. The arc-shaped maintenance plate 41 is threadedly connected to the bolt mounting holes 40 of the support rod 39 through fixing bolts 42.

[0035] During use, when it is necessary to replace the membrane filter 3, the corresponding fixing bolts 42 are unscrewed. Since the arc-shaped maintenance plate 41 is threadedly connected to the bolt mounting holes 40 of the support rod 39 through the fixing bolts 42, after the fixing bolts 42 are unscrewed, the arc-shaped maintenance plate 41 is separated from the support rod 39. At this time, the space between the diversion baffle 2 and the liquid collection cylinder 4 is enlarged, and maintenance personnel can easily access the connection between the membrane filter 3 and the threaded mounting pipe 29, and then perform the replacement operation on the membrane filter 3. After completing the replacement of the membrane filter 3, the arc-shaped maintenance plate 41 is reinstalled on the support rod 39, the fixing bolts 42 are passed through the corresponding positions on the arc-shaped maintenance plate 41, screwed into the bolt mounting holes 40 of the support rod 39 and tightened, so that the arc-shaped maintenance plate 41 is fixed outside the support rod 39, reducing the difficulty of replacing the membrane filter 3.

[0036] The present invention also provides a separation and purification process for malt syrup saccharification liquid, using the above-mentioned separation and purification equipment for malt syrup saccharification liquid, including the following steps: Step 1: Introduce the saccharification liquid into the separation tank and complete preliminary filtration through the coarse filtration component; Step 2: The saccharified liquid converges to the piston-type extrusion liquid supply component through the shunt baffle; Step 3: Adjust the driving speed of the driving structure according to the liquid inlet speed of the saccharified liquid, and press the saccharified liquid into the membrane filter by driving the piston-type extrusion liquid supply component through the driving structure; Step 4: The membrane filter supplies the filtered saccharified liquid into the liquid collection cylinder.

[0037] When the present invention is in use, the malt syrup saccharified liquid is introduced from the liquid inlet pipe 38 on one side of the upper part of the separation tank. The driving motor 14 is started, driving the output shaft 15 to rotate, so that the stirring rod 36 on the output shaft 15 stirs the saccharified liquid that has just entered the separation tank 1, making the saccharified liquid evenly distributed. Under the stirring action, the saccharified liquid flows towards the sector-shaped filter plate 35 on the connecting plate 33 and is preliminarily filtered through the sector-shaped groove 34. Large-particle impurities are intercepted on the sector-shaped filter plate 35. The saccharified liquid that has passed through the coarse filtration passes through the sector-shaped groove 34, part of it falls on the conical guide plate 16, and then flows downward through the communication hole 37 to the shunt baffle 2; When the saccharified liquid falls on the shunt baffle 2, at this time, the piston-type extrusion liquid supply component is in the initial position. The piston plate 7 is located above the piston cylinder 6 under the action of the return spring 10, and the piston cylinder 6 is not yet filled with liquid. The saccharified liquid flows into the piston cylinder 6 through the liquid inlet 11 on one side of the upper part of the piston cylinder 6; The driving motor 14 operates, driving the conical guide plate 16 to rotate, so that the arc-shaped extrusion plate 19 moves synchronously. The wedge-shaped guide surface 20 at the lower part of the arc-shaped extrusion plate 19 squeezes the extrusion roller 13, driving the movable pipe 8 and the piston plate 7 to slide downward in the piston cylinder 6. The piston plate 7 squeezes the saccharified liquid in the piston cylinder 6. Under the guidance of the positioning slide rod 9, the saccharified liquid is finely filtered through the membrane filter 3 connected to the lower part of the piston cylinder 6 to remove tiny impurities such as proteins, colloidal substances, and microorganisms. The filtered pure malt syrup flows into the liquid collection cylinder 4 and is discharged through the drain pipe 31 on the lower surface of the liquid collection cylinder 4 for subsequent processing; after the piston plate 7 is separated from the extrusion roller 13 by the driving structure, it is pushed upward to reset by the return spring 10, and a negative pressure is formed in the piston cylinder 6, and the saccharified liquid that has passed through the coarse filtration is sucked in again through the liquid inlet 11 to prepare for the next extrusion liquid supply; When the liquid inlet volume of the saccharified liquid in the separation tank 1 increases, in order to ensure the efficient and stable operation of the equipment, it is necessary to correspondingly increase the rotation speed of the driving motor 14. After the rotation speed of the driving motor 14 is increased, it drives the conical guide plate 16 to rotate at an accelerated speed, and makes the movement speeds of the slider 18 and the arc-shaped extrusion plate 19 connected to the conical guide plate 16 increase significantly. Furthermore, the extrusion frequency between the wedge-shaped guide surface 20 and the extrusion roller 13 is increased, so that the extrusion efficiency can match the liquid inlet volume, effectively accelerating the filtration speed and ensuring that the saccharified liquid can be processed in time. When the actual liquid inflow increases and the requirement for filtration efficiency improves, the position of the arc-shaped pressing plate 19 can be adjusted to prompt a greater downward movement of the piston plate 7, increasing the amount of saccharified liquid flowing into the membrane filter 3 to meet higher filtration requirements. Conversely, if the liquid inflow decreases or the filtration efficiency requirement decreases, the position of the arc-shaped pressing plate 19 can be appropriately adjusted to reduce the vertical movement range of the pressing roller 13 when it is pressed, and the downward movement amplitude of the piston plate 7 will also be correspondingly reduced, avoiding energy waste or equipment loss caused by excessive pressing; If a certain membrane filter 3 needs to be replaced, find the piston-type extrusion liquid supply assembly corresponding to the membrane filter 3 to be replaced, close the ferrule quick-install ball valve 28 installed on the lower surface of the piston cylinder 6 to prevent the malt syrup saccharified liquid from continuing to flow into this membrane filter 3; Unscrew the fixing bolt 42 at the position of the corresponding membrane filter 3 to separate the arc-shaped maintenance plate 41 from the support rod 39. Removing the arc-shaped maintenance plate 41 can expand the space between the flow diversion baffle 2 and the liquid collection cylinder 4, facilitating maintenance personnel to access the connection between the membrane filter 3 and the threaded installation pipe 29; Unscrew the nut 30 connecting the liquid collection cylinder 4 to this membrane filter 3 and remove the membrane filter 3. After removing the membrane filter 3, rotate the piston cylinder 6. Utilize the sliding connection between the arc-shaped rotating plate 25 on the outer side of the lower end of the piston cylinder 6 and the rotating groove 27 on the lower surface limiting plate 26 of the flow diversion baffle 2 to rotate the piston cylinder 6 to a suitable position, so that the piston-type extrusion liquid supply assembly is re-slidingly connected to the flow diversion baffle 2. Under the subsequent action of gravity and the driving structure, the piston cylinder 6 moves downward and maintains a sliding connection state with the flow diversion baffle 2, ensuring that other piston-type extrusion liquid supply assemblies are not affected and can carry out the filtration work normally; Align the upper end of the new membrane filter 3 with the ferrule quick-install ball valve 28 on the lower surface of the piston cylinder 6, and through the quick connection of the ferrule quick-install ball valve 28, then connect the lower end of the membrane filter 3 to the threaded installation pipe 29 on the liquid collection cylinder 4, tighten the nut 30 for fixation, rotate the piston cylinder 6 and carry out positioning so that it is no longer slidingly connected to the flow diversion baffle 2. Finally, open the ferrule quick-install ball valve 28 to open the liquid inlet channel. At this time, the liquid on the flow diversion baffle 2 will enter the newly installed membrane filter 3 under the extrusion of the piston-type extrusion liquid supply assembly, and the filtration work of this assembly will be successfully restored; The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
