Description

Technical Field

[0001] The invention relates to the technical field of saccharification devices, and in particular to a filtering device and process for beer saccharification production. Background Art

[0002] The pot is a key equipment in the beer brewing industry. It is mainly used to convert starch in raw materials such as malt into sugar. The pot body is generally made of stainless steel with a heating device and a stirrer. The heating can accurately control the temperature and promote the decomposition of starch. The stirrer makes the raw materials evenly heated and mixed to ensure that the saccharification reaction is fully carried out. It is the core container of the saccharification process.

[0003] The above-mentioned and prior arts have the following defects: during the saccharification process of malt, the generated steam will contain small particles, which will be mixed into the malt solution again after the steam is cooled. Due to their small size, it is difficult to filter out the particles in the subsequent malt filtering process, which causes the particles to have an adverse effect on the quality of the beer, thereby reducing the practicality of the saccharification equipment.

[0004] Therefore, a filtering device and process for beer saccharification production are proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that particulate matter will be mixed into the malt solution again after steam cooling. Due to its small volume, it is difficult to filter out the particulate matter in the subsequent malt filtering process, which causes the particulate matter to have an adverse effect on the quality of beer. A filtering device and process for beer saccharification production are proposed to solve the problem that particulate matter will be mixed into the malt solution again after steam cooling. Due to its small volume, it is difficult to filter out the particulate matter in the subsequent malt filtering process, which causes the particulate matter to have an adverse effect on the quality of beer.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a filtering device and process for beer saccharification production, comprising a pot tank, the outer wall of which is fixedly equipped with a treatment box, and further comprising: A filtering structure is arranged on the inner wall of the processing box and is used to filter particulate matter in the steam. The filtering structure includes a plurality of guide pipes for discharging the steam into the water, a bubble breaking net for reducing the volume of bubbles, a bending plate and a plurality of transmission plates that cooperate with each other to drive the bubble breaking net to vibrate; A protective structure arranged on the side wall of the processing box to ensure that the bubble breaking net can vibrate normally, the protective structure comprising a strip plate fixedly mounted on the side wall of the processing box and a protective cover for shielding the contact point between the transmission plate and the bending plate; An overflow structure is arranged on the side wall of the processing box and is used to control the liquid level in the processing box. The overflow structure includes a turntable rotatably installed on the side wall of the processing box and an overflow pipe for guiding water.

[0007] The effects achieved by the above components are as follows: by setting up a filtering structure, in the process of saccharifying the malt, the particulate matter is captured and filtered with the help of water, thereby purifying the steam, preventing the particulate matter from being mixed into the malt solution again and causing adverse effects on the quality of the beer, thereby improving the practicality of the saccharification equipment; by setting up a protective structure, in the process of filtering the steam, the contact point of the bending plate and the transmission plate can be shielded with the help of a protective cover, preventing foreign objects from being stuck between the bending plate and the transmission plate; by setting up an overflow structure, in the process of filtering the steam, excess water will flow into the transfer pipe through the overflow pipe, thereby avoiding excessive water, which causes sewage to enter the exhaust pipe and flow into the pot tank.

[0008] Preferably, an air pump is fixedly connected to the upper surface of the processing box, and an air inlet end of the air pump is fixedly connected to a heat preservation pipe, which passes through the boiler tank, and an exhaust end of the air pump is fixedly connected to a cooling pipe, and an exhaust pipe is fixedly connected to the upper surface of the processing box, and the exhaust pipe passes through the boiler tank, and an inlet pipe is fixedly connected to the upper surface of the processing box, and a valve pipe is fixedly connected to the lower surface of the processing box, and a rotating pipe is horizontally rotatably connected inside the processing box, and a baffle is horizontally fixedly connected to the inner wall of the processing box, and the rotating pipe is sleeved on the outer arc surface of the baffle, one end of the cooling pipe passes through the processing box and abuts against the inner arc surface of the baffle, and the guide pipe is fixedly connected and assembled on the circumferential surface of the rotating pipe, and the bending plate passes through the processing box, and one end of the bending plate is fixedly connected to the bubble breaking net, and the bubble breaking net is slidably connected to the processing box, and the transmission plate is fixedly installed on the circumferential surface of the rotating pipe.

[0009] The effects achieved by the above components are: close the water inlet pipe, then turn on the air pump, at this time the insulation pipe will suck the steam in the pot tank, the insulation pipe can maintain the temperature of the steam, prevent the steam from condensing in the insulation pipe and affecting the normal operation of the air pump, the steam will be transported to the cooling pipe by the air pump, the cooling pipe will absorb the heat in the steam, the steam will quickly cool and condense into water droplets, when the water droplets come into contact with the particles, they will capture the particles, thereby preliminarily removing the particles, and then the air will be transported to the baffle and discharged by the guide pipe, at this time with the help of water The particles in the air are captured. When the rotating tube rotates, the transmission plate will rotate synchronously. After the transmission plate contacts the bending plate, the bending plate will drive the bubble breaking net to move upward along the fixed tube and the processing box. When the bending plate is out of contact with the transmission plate, the bubble breaking net will slide downward quickly. When the bubble breaking net contacts the bubbles, it will break up the bubbles again, further allowing the particles to contact with water, thereby ensuring the filtering effect on the air. The bubble breaking net can also continue to break up the bubbles within a certain range by moving back and forth in the vertical direction, thereby preventing the bubbles from gathering together again.

[0010] Preferably, one end of the guide tube away from the rotating tube is in a bent structure, and the vertical cross-section of the baffle is in a "C" shape.

[0011] The effect achieved by the above components is that by setting one end of the diversion pipe into a bent structure, when air is discharged, the reaction force generated by the air flow will cause the diversion pipe to drive the rotating pipe to rotate.

[0012] Preferably, several of the diversion pipes are spirally distributed along the radial direction of the rotating pipe.

[0013] The effect achieved by the above components is that by spirally distributing the diversion pipes along the radial direction of the rotating pipe, the situation where the baffle blocks all the diversion pipes can be avoided, so as to ensure that there is always air discharged from some of the diversion pipes.

[0014] Preferably, a fixed pipe is fixedly connected to the side wall of the treatment box, the bent plate penetrates through the fixed pipe, a threaded column is fixedly connected to the outer wall of the fixed pipe, a nut is threadedly connected to the arc surface of the threaded column, a connecting ring is rotatably connected to the upper end of the nut, a spring is fixedly connected to the upper end of the connecting ring, an extension plate is fixedly connected to the surface of the bent plate, one end of the spring is fixedly connected to the extension plate, and the threaded column penetrates through the connecting ring, the spring and the extension plate.

[0015] The effect achieved by the above components is that when it is necessary to adjust the elastic force of the spring, rotate the nut, and the nut will move along the arc surface of the threaded column by means of the thread. When the nut moves upward, the elongation of the spring shortens and the elastic force becomes smaller. At this time, the transmission plate can move the bubble-breaking net upward with a smaller force. When the nut moves downward, the elongation of the spring extends and the elastic force becomes larger. Therefore, the bubble-breaking net can move downward faster. Therefore, the elastic force of the spring can be adjusted according to needs to ensure that the bubble-breaking net can work normally.

[0016] Preferably, the protective cover is rotatably connected to the strip-shaped plate, a support bar is fixedly connected to the outer wall of the treatment box, a clamping plate is slidably sleeved on the surface of the support bar, a leaf spring is fixedly connected to the surface of the clamping plate, and one end of the leaf spring is fixedly connected to the treatment box.

[0017] The effect achieved by the above components is that when pushing the clamping plate in the direction close to the treatment box, the clamping plate sliding along the surface of the support bar will compress the leaf spring. When the clamping plate is separated from the protective cover, the protective cover can be rotated downward to the vertical state. At this time, the protective cover will block the contact point between the bent plate and the transmission plate, avoiding the situation where foreign objects are stuck between the bent plate and the transmission plate.

[0018] Preferably, the vertical cross-section of the clamping plate is in a "ji" shape.

[0019] The effect achieved by the above components is that the clamping plate with a vertical cross-section in a "ji" shape can not only increase the resistance when the protective cover rotates, ensure the protective effect of the protective cover on the contact point between the transmission plate and the bent plate, but also limit the position of the protective cover, facilitating the adjustment of the elastic force of the spring.

[0020] Preferably, the overflow pipe is fixedly connected and assembled on the surface of the turntable, the circumferential surface of the overflow pipe is rotatably connected to a transfer tube, the outer wall of the processing box is fixedly connected to an L-shaped plate, and the inner thread of the L-shaped plate is connected to bolts.

[0021] The effect achieved by the above components is: in the process of filtering steam, the amount of water in the treatment box will gradually increase. When the water level rises to the overflow pipe, the excess water will flow into the transfer pipe through the overflow pipe, thereby avoiding excessive water, which will cause sewage to enter the exhaust pipe and flow into the pot tank. When it is necessary to adjust the liquid level in the treatment box, turn the turntable, the turntable will drive the overflow pipe to move, so that the height of the overflow pipe can be adjusted, and then the liquid level in the treatment box can be adjusted.

[0022] Preferably, a pressure plate is rotatably connected to one end of the bolt close to the turntable, and a friction strip is fixedly connected to the surface of the turntable.

[0023] The effect achieved by the above components is that the friction strip can increase the friction between the bolt and the turntable, thereby ensuring the limiting effect of the bolt on the turntable.

Raw material selection and processing: select deep groundwater that has been filtered through multiple stages, malt that has been malted, hops, beer adjuncts and yeast; S2, saccharification treatment: through the gelatinization pot, pot tank, boiling pot, filter tank, sedimentation tank, the solid raw materials are turned into liquid wort; S3, filtering and boiling: completing solid-liquid separation through the filtering device for beer saccharification production to obtain clarified wort and obtain a good yield, and at the same time, the boiling device is used to stabilize the wort components on the one hand, and on the other hand, to increase the steam overflow in the filtering device for beer saccharification production, and eliminate the bad flavor-affecting substances in the steam; After the steam is filtered, it enters the exhaust chimney through the exhaust pipe, and passes through the recycling treatment area, thermal energy adsorption treatment area, pH treatment area, chemical neutralization treatment area in turn, and finally discharged; S4, sedimentation: separation of heat coagulation in wort; S5. Cooling: Lower the temperature to meet the requirements for yeast fermentation, and oxygenate the wort so that it absorbs an appropriate amount of oxygen, provides the material conditions required for yeast growth and reproduction, and precipitates cold condensates to improve fermentation conditions and improve beer quality.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are: 1.

[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1:

[0032] like Figure 1-Figure 10 As shown, the present invention provides a filtering device and process for beer saccharification production, including a pot tank 1, a processing box 2 is fixedly mounted on the outer wall of the pot tank 1, and also includes: A filtering structure is arranged on the inner wall of the processing box 2 and is used to filter particulate matter in the steam. The filtering structure includes a plurality of guide pipes 10 for discharging the steam into the water, a bubble breaking net 13 for reducing the volume of bubbles, a bending plate 12 and a plurality of transmission plates 14 that cooperate with each other to drive the bubble breaking net 13 to vibrate; A protective structure arranged on the side wall of the processing box 2 to ensure that the bubble breaking net 13 can vibrate normally, the protective structure includes a strip plate 21 fixedly installed on the side wall of the processing box 2, and a protective cover 22 for shielding the contact point between the transmission plate 14 and the bending plate 12; An overflow structure is arranged on the side wall of the processing box 2 to control the liquid level in the processing box 2. The overflow structure includes a turntable 26 rotatably mounted on the side wall of the processing box 2 and an overflow pipe 27 for guiding water.

[0033] The following is a detailed description of the specific settings and functions of its filtration structure, protection structure and overflow structure.

[0034] like Figure 3-Figure 7As shown, the upper surface of the processing box 2 is fixedly connected with an air pump 3, the air inlet end of the air pump 3 is fixedly connected with a heat preservation pipe 4, the heat preservation pipe 4 runs through the pot tank 1, the exhaust end of the air pump 3 is fixedly connected with a cooling pipe 5, the upper surface of the processing box 2 is fixedly connected with an exhaust pipe 6, the exhaust pipe 6 runs through the pot tank 1, the upper surface of the processing box 2 is fixedly connected with a water inlet pipe 7, the lower surface of the processing box 2 is fixedly connected with a valve pipe 8, the processing box 2 is horizontally rotatably connected with a rotating pipe 9, the inner wall of the processing box 2 is horizontally fixedly connected with a baffle 11, and the rotating pipe 9 is sleeved on The outer arc surface of the baffle 11, one end of the cooling pipe 5 passes through the processing box 2 and abuts against the inner arc surface of the baffle 11, the guide pipe 10 is fixedly connected and assembled on the circumferential surface of the rotating pipe 9, the bending plate 12 passes through the processing box 2, one end of the bending plate 12 is fixedly connected to the bubble breaking net 13, the bubble breaking net 13 is slidably connected to the processing box 2, the transmission plate 14 is fixedly installed on the circumferential surface of the rotating pipe 9, the water inlet pipe 7 is closed, and then the air pump 3 is turned on. At this time, the insulation pipe 4 will suck the steam in the pot tank 1, and the insulation pipe 4 can maintain the temperature of the steam to prevent the steam from being in the insulation If the condensation in the warm pipe 4 affects the normal operation of the air pump 3, the steam will be transported to the cooling pipe 5 by the air pump 3. The cooling pipe 5 will absorb the heat in the steam, and the steam will quickly cool and condense into water droplets. When the water droplets come into contact with the particles, they will capture the particles, thereby preliminarily removing the particles. After that, the air will be transported to the baffle 11 and discharged by the guide pipe 10. At this time, the particles in the air can be captured with the help of water. When the rotating pipe 9 rotates, the transmission plate 14 will rotate synchronously, and the transmission plate 14 and the curved After the folding plate 12 contacts, the bending plate 12 will drive the bubble breaking net 13 to move upward along the fixed tube 15 and the processing box 2. When the bending plate 12 is out of contact with the transmission plate 14, the bubble breaking net 13 will slide downward quickly. When the bubble breaking net 13 contacts the bubbles, the bubble breaking net 13 will break up the bubbles again, further making the particulate matter contact with water, thereby ensuring the filtering effect on the air. In addition, the bubble breaking net 13 can continue to break up the bubbles within a certain range by moving back and forth in the vertical direction, thereby preventing the bubbles from gathering together again.

[0035] One end of the guide tube 10 away from the rotating tube 9 is in a bent structure, and the vertical cross-section of the baffle 11 is in a "C" shape. By setting one end of the guide tube 10 to be in a bent structure, when air is discharged, the reaction force generated by the air flow will cause the guide tube 10 to drive the rotating tube 9 to rotate.

[0036] The plurality of guide tubes 10 are distributed in a spiral shape along the radial direction of the rotating tube 9 . By distributing the guide tubes 10 in a spiral shape along the radial direction of the rotating tube 9 , it is possible to avoid the baffle 11 blocking all the guide tubes 10 , thereby ensuring that air is always discharged from some of the guide tubes 10 .

[0037] A fixed pipe 15 is fixedly connected to the side wall of the processing box 2. The bending plate 12 passes through the fixed pipe 15. A threaded column 16 is fixedly connected to the outer wall of the fixed pipe 15. A nut 17 is threadedly connected to the arc surface of the threaded column 16. The upper end of the nut 17 is rotatably connected to a connecting ring 18. A spring 19 is fixedly connected to the upper end of the connecting ring 18. An extension plate 20 is fixedly connected to the surface of the bending plate 12. One end of the spring 19 is fixedly connected to the extension plate 20. The threaded column 16 passes through the connecting ring 18, the spring 19 and the extension plate 20. When it is necessary to adjust the elastic force of the spring 19, rotate the nut 17, and the nut 17 will move along the arc surface of the threaded column 16 by means of the thread. When the nut 17 moves upward, the elongation of the spring 19 shortens and the elastic force becomes smaller. At this time, the transmission plate 14 can move the bubble-breaking net 13 upward with a smaller force. When the nut 17 moves downward, the elongation of the spring 19 extends and the elastic force becomes larger. Therefore, the bubble-breaking net 13 can move downward faster. Therefore, the elastic force of the spring 19 can be adjusted according to needs to ensure that the bubble-breaking net 13 can work properly.

[0038] As Figure 7-Figure 9 shown, the protective cover 22 is rotatably connected to the strip-shaped plate 21. A support strip 23 is fixedly connected to the outer wall of the processing box 2. A clamping plate 24 is slidably sleeved on the surface of the support strip 23. A leaf spring 25 is fixedly connected to the surface of the clamping plate 24. One end of the leaf spring 25 is fixedly connected to the processing box 2. Push the clamping plate 24 in the direction close to the processing box 2, and the clamping plate 24 will slide along the surface of the support strip 23 and compress the leaf spring 25. When the clamping plate 24 is disengaged from the protective cover 22, the protective cover 22 can be rotated downward to the vertical state. At this time, the protective cover 22 will block the contact point between the bending plate 12 and the transmission plate 14, avoiding the situation that foreign objects are stuck between the bending plate 12 and the transmission plate 14.

[0039] The vertical cross-section of the clamping plate 24 is in a "Ji" shape. The clamping plate 24 with a vertical cross-section in a "Ji" shape can not only increase the resistance when the protective cover 22 rotates, ensure the protective effect of the protective cover 22 on the contact point between the transmission plate 14 and the bending plate 12, but also limit the position of the protective cover 22, facilitating the adjustment of the elastic force of the spring 19.

[0040] As Fig.10As shown, the overflow pipe 27 is fixedly connected and assembled on the surface of the turntable 26, and the circumferential surface of the overflow pipe 27 is rotatably connected to the transfer pipe 28. The outer wall of the treatment box 2 is fixedly connected to the L-shaped plate 29, and the inner thread of the L-shaped plate 29 is connected to the bolt 30. In the process of filtering steam, the amount of water in the treatment box 2 will gradually increase. When the water level rises to the overflow pipe 27, the excess water will flow into the transfer pipe 28 through the overflow pipe 27, thereby avoiding the situation where too much water causes sewage to enter the exhaust pipe 6 and flow into the boiler tank 1. When it is necessary to adjust the liquid level in the treatment box 2, the turntable 26 is rotated, and the turntable 26 will drive the overflow pipe 27 to move, so that the height of the overflow pipe 27 can be adjusted, and then the liquid level in the treatment box 2 can be adjusted.

[0041] The end of the bolt 30 close to the turntable 26 is rotatably connected to a pressure plate 31 , and the surface of the turntable 26 is fixedly connected to a friction strip 32 , which can increase the friction between the bolt 30 and the turntable 26 , thereby ensuring the limiting effect of the bolt 30 on the turntable 26 .

[0042] The filtration process for beer saccharification production includes the following steps: S1. Raw material selection and processing: select deep groundwater that has been filtered through multiple stages, malt that has been malted, hops, beer adjuncts and yeast; S2, saccharification treatment: through the gelatinization pot, pot tank 1, boiling pot, filter tank, sedimentation tank, the solid raw materials are converted into liquid wort; S3, filtering and boiling: completing solid-liquid separation through the filtering device for beer saccharification production to obtain clarified wort and obtain a good yield, and at the same time, the boiling device is used to stabilize the wort components on the one hand, and on the other hand, to increase the steam overflow in the filtering device for beer saccharification production, and eliminate the bad flavor-affecting substances in the steam; After the steam is filtered, it enters the exhaust chimney through the exhaust pipe, and passes through the recycling treatment area, thermal energy adsorption treatment area, pH treatment area, chemical neutralization treatment area in turn, and finally discharged; S4, sedimentation: separation of heat coagulation in wort; S5. Cooling: Lower the temperature to meet the requirements for yeast fermentation, and oxygenate the wort so that it absorbs an appropriate amount of oxygen, provides the material conditions required for yeast growth and reproduction, and precipitates cold condensates to improve fermentation conditions and improve beer quality.

[0043] The method for using the filtering device for beer saccharification production comprises the following steps: S1, connect the external water pipe to the water inlet pipe 7 and the transfer pipe 28, then close the valve pipe 8 and inject water into the treatment box 2 through the water inlet pipe 7; S2, close the water inlet pipe 7 and start the air pump 3, the steam flows through the insulation pipe 4, the air pump 3, the cooling pipe 5, the baffle 11, the rotating pipe 9, and finally discharged by the guide pipe 10, and the particles will be captured by the water when they come into contact with the water; S3, rotating the protective cover 22 to a vertical state, the protective cover 22 will cover the contact point between the bending plate 12 and the transmission plate 14; S4, rotating the turntable 26, the turntable 26 will drive the overflow pipe 27 to move, so that the height of the overflow pipe 27 can be adjusted, and then the height of the liquid level in the processing box 2 can be adjusted to keep the water volume at a normal state; S5. When the bubbles break on the water surface, the clean air will flow back into the pot tank 1 through the exhaust pipe 6.

[0044] The overall working principle is that during the saccharification process of malt, steam containing particulate matter will be generated in the boiler tank 1. When the particulate matter needs to be removed, first connect the external water pipe to the water inlet pipe 7 and the transfer pipe 28, then close the valve pipe 8 and inject water into the processing box 2 through the water inlet pipe 7, then close the water inlet pipe 7, and then turn on the air pump 3. At this time, the insulation pipe 4 will suck the steam in the boiler tank 1. The insulation pipe 4 can maintain the temperature of the steam to prevent the steam from condensing in the insulation pipe 4 and affecting the normal operation of the air pump 3. The steam will be transported to the cooling pipe 5 by the air pump 3. The cooling pipe 5 will absorb the heat in the steam. The steam will quickly cool and condense into water droplets. When the water droplets come into contact with the particulate matter, they will capture the particulate matter, thereby After the particles are initially removed, the air will be transported to the baffle 11 and discharged by the guide pipe 10. By setting one end of the guide pipe 10 into a bent structure, when the air is discharged, the reaction force generated by the air flow will cause the guide pipe 10 to drive the rotating pipe 9 to rotate. Under the restriction of the baffle 11, it can be ensured that the air is transported to the bottom of the water in the treatment box 2. At the same time, the guide pipe 10 will also stir the water flow to break the large bubbles floating in the water flow, so that the particles in the bubbles are fully in contact with the water. By making the guide pipe 10 spirally distributed along the radial direction of the rotating pipe 9, it can be avoided that the baffle 11 blocks all the guide pipes 10, thereby ensuring that there is always air discharged from part of the guide pipe 10. Therefore, when the air pump 3, the rotating tube 9 can always rotate normally. When the rotating tube 9 rotates, the transmission plate 14 will rotate synchronously. After the transmission plate 14 contacts the bending plate 12, the bending plate 12 will drive the bubble breaking net 13 to move upward along the fixed tube 15 and the processing box 2. At the same time, the extension plate 20 follows the movement of the bending plate 12 to stretch the spring 19. When the bending plate 12 is out of contact with the transmission plate 14, the spring 19 contracts, and the extension plate 20 slides downward with the elastic force of the spring 19. Therefore, the bubble breaking net 13 will also slide downward quickly. When the bubble breaking net 13 contacts the bubbles, the bubble breaking net 13 will break up the bubbles again, further making the particles contact with water, thereby ensuring the filtering effect on the air. In addition, the bubble breaking net 13 can also move back and forth in the vertical direction. The bubbles are continuously dispersed within a certain range to prevent the bubbles from gathering together again. When the elastic force of the spring 19 needs to be adjusted, the nut 17 is rotated, and the nut 17 moves along the arc surface of the threaded column 16 with the help of the thread. When the nut 17 moves upward, the elongation of the spring 19 is shortened and the elastic force becomes smaller. At this time, the transmission plate 14 can move the bubble breaking net 13 upward with a smaller force. When the nut 17 moves downward, the elongation of the spring 19 is extended and the elastic force becomes larger. Therefore, the bubble breaking net 13 can move downward faster. Therefore, the elastic force of the spring 19 can be adjusted as needed to ensure that the bubble breaking net 13 can work normally. When the bubbles are broken on the water surface, clean air will flow back into the pot tank 1 through the exhaust pipe 6.

[0045] In the process of filtering steam, it is necessary to prevent foreign objects from interfering with the movement of the transmission plate 14 driving the bending plate 12. The card plate 24 is pushed in the direction close to the processing box 2. The card plate 24 slides along the surface of the support bar 23 to compress the leaf spring 25. When the card plate 24 is out of contact with the protective cover 22, the protective cover 22 can be rotated downward to a vertical state. At this time, the protective cover 22 will block the contact point between the bending plate 12 and the transmission plate 14 to prevent foreign objects from being stuck between the bending plate 12 and the transmission plate 14. At the same time, the card plate 24 will use the elastic force of the leaf spring 25 to press against the inner wall of the protective cover 22. The card plate 24 will use the elastic force of the spring 19 to increase the resistance of the protective cover 22 when it rotates, ensuring To improve the protective effect of the protective cover 22, when it is necessary to adjust the elastic force of the spring 19, the protective cover 22 is rotated upward to a horizontal state. During this process, the protective cover 22 will continue to squeeze the card plate 24. When the protective cover 22 is rotated to a horizontal state, the card plate 24 will engage with the protective cover 22 with the help of the elastic force of the leaf spring 25. The card plate 24 reaches the limit position of the protective cover 22, thereby facilitating the subsequent adjustment of the elastic force of the spring 19. Therefore, the card plate 24 with a "J" shape in the vertical section can increase the resistance of the protective cover 22 during rotation, ensure the protective effect of the protective cover 22 on the contact point of the transmission plate 14 and the bending plate 12, and can also limit the position of the protective cover 22, which is convenient for adjusting the elastic force of the spring 19.

[0046] In the process of filtering steam, the amount of water in the treatment box 2 will gradually increase. When the water level rises to the overflow pipe 27, the excess water will flow into the transfer pipe 28 through the overflow pipe 27, thereby avoiding the situation where there is too much water, causing sewage to enter the exhaust pipe 6 and flow into the boiler tank 1. When it is necessary to adjust the liquid level in the treatment box 2, the turntable 26 is rotated, and the turntable 26 will drive the overflow pipe 27 to move, so that the height of the overflow pipe 27 can be adjusted, and then the liquid level in the treatment box 2 can be adjusted to keep the water level normal. After the adjustment is completed, the bolt 30 is rotated, and the bolt 30 will drive the pressure plate 31 to move toward the direction close to the friction strip 32 by means of the thread. When the pressure plate 31 is against the surface of the friction strip 32, the pressure plate 31 reaches the position of limiting the friction strip 32, thereby limiting the position of the turntable 26. The friction strip 32 can increase the friction between the bolt 30 and the turntable 26, thereby ensuring the limiting effect of the bolt 30 on the turntable 26.

[0047] Example 2: Please refer to Fig.11 and Fig.12, this embodiment further illustrates the first embodiment, the outer wall of the treatment box 2 is fixedly connected to a motor 33, the output end of the motor 33 is fixedly connected to the rotating tube 9, the surface of the bending plate 12 is provided with a water storage tank 34, the lower end of the bending plate 12 is fixedly connected to a nozzle 35 connected to the water storage tank 34, the inner wall of the treatment box 2 is fixedly connected to a blocking strip 36, the blocking strip 36 is slidably connected to the water storage tank 34, when the motor 33 is turned on, the motor 33 will drive the rotating tube 9 to rotate, when the transmission plate 14 squeezes and bends When the plate 12 is moved downward, the water will flow back into the water tank 34. Therefore, as the motor 33 continues to run, the nozzle 35 can continuously generate a jet to break up the bubbles.
