Description

Technical Field

[0001] The invention relates to the technical field of acrylic resin production, and in particular to intelligent filtering equipment for acrylic resin production. Background Art

[0002] Acrylic resin is a synthetic polymer material, mainly formed by the polymerization of acrylic ester monomers. This type of resin has many properties, including good transparency, weather resistance and chemical corrosion resistance. Due to these excellent properties, acrylic resin is widely used in many industries.

[0003] When producing acrylic resin, since the acrylic resin contains impurities such as solid particles and unreacted monomers, the acrylic resin needs to be filtered. When filtering the acrylic resin, a filter element filter is partially used. The filtering method of the filter element filter is to use the ultrafiltration membrane inside the filter element to allow the acrylic resin to pass through each membrane filament on the ultrafiltration membrane under the action of pressure, so as to intercept the impurities in the acrylic resin and filter the acrylic resin. When the existing ultrafiltration membrane filter element filter is used to filter the acrylic resin, since the solid impurities in the acrylic resin adhere to the membrane filaments of the ultrafiltration membrane during the filtration process, the impurities adhered to the ultrafiltration membrane cannot be cleaned in time, resulting in a gradual reduction in the filtration area of ​​the membrane filaments, a gradual reduction in the filtration efficiency, and even clogging of the filter element, making it impossible to perform normal filtration.

[0004] Furthermore, since acrylic resin has a certain viscosity, when using an ultrafiltration membrane filter element to filter the acrylic resin, most of the impurities adhere to the outside of the ultrafiltration membrane, causing most of the acrylic resin to be blocked on the outside of the ultrafiltration membrane and unable to fully contact the membrane filaments in the middle of the ultrafiltration membrane. The utilization rate of the membrane filaments in the middle is low, resulting in low filtration efficiency of the acrylic resin. Summary of the invention

[0025] Each partition plate 204 is provided with a plurality of one-way air holes 20401 in a circular array.

[0026] Each scraper 3 is provided with a blocking portion 3002 .

[0027] It also includes a comber 6 and a second elastic rope 7; two combers 6 are slidably connected to each scraper 3; a number of combing rods 6001 are arranged on each comber 6; the combers 6 on each scraper 3 are in contact with the combers 6 on the adjacent scraper 3, and the combing rods 6001 thereon are stacked up and down; every two adjacent combers 6 cooperate to form a number of second limiting grooves 6002; the membrane filaments on the ultrafiltration membrane 2 are located in the second limiting grooves 6002; two second elastic ropes 7 are fixedly connected to each scraper 3; each second elastic rope 7 is fixedly connected to the corresponding comber 6.

[0029] The present invention scrapes and collects the solid impurities adhered to the ultrafiltration membrane 2 by a scraper 3, thereby reducing the solid impurities adhered to the ultrafiltration membrane 2, and solving the problem that the solid impurities in the acrylic resin adhere to the ultrafiltration membrane 2 during the filtration process, resulting in a gradual reduction in the filtration area of ​​the ultrafiltration membrane 2 and a reduction in the filtration efficiency. The specific process is as follows: When filtering acrylic resin, the movable block 106 is initially located in the middle of the liquid inlet pipe 101. At the same time, the scraper 3 contacts the inner wall of the expansion part 1001 under the elastic force of the elastic member 107, driving the comber 6 to approach the inner wall of the filter tank 1, so that the combing rod 6001 drives the middle part of the membrane filament of the ultrafiltration membrane 2 to move toward the inner wall of the expansion part 1001, so that the middle part of the ultrafiltration membrane 2 is in an expanded state. Figure 7 As shown, during this process, the combing rods 6001 on the two adjacent combs 6 are always in a fitted state, so that the second limiting groove 6002 is always in a closed state, ensuring the limiting effect on the membrane filaments of the ultrafiltration membrane 2, and preventing the membrane filaments of the ultrafiltration membrane 2 from escaping from the combing device 6 and thus returning to their original state. When filtering acrylic resin, it is beneficial for the acrylic resin to fully contact with the membrane filaments in the middle of the ultrafiltration membrane 2, preventing the acrylic resin from accumulating on the outside of the ultrafiltration membrane 2 due to viscosity, and preventing the acrylic resin from being unable to fully contact with the membrane filaments in the middle of the ultrafiltration membrane 2, thereby improving the utilization rate of the membrane filaments in the middle of the ultrafiltration membrane 2 and enhancing the filtering effect of the ultrafiltration membrane 2 on acrylic resin.

[0030] After the middle part of the ultrafiltration membrane 2 expands, the external feeding equipment is controlled to transfer the acrylic resin from the liquid inlet pipe 101 to the inside of the filter tank 1, so that the acrylic resin is sprayed from the spray hole 10101 in the middle of the ultrafiltration membrane 2 to the outside of the ultrafiltration membrane 2, thereby making the acrylic resin fully contact with each membrane filament on the ultrafiltration membrane 2, thereby improving the filtration efficiency of the ultrafiltration membrane 2 for the acrylic resin, and further enhancing the filtration effect of the ultrafiltration membrane 2 for the acrylic resin. After the acrylic resin enters the inside of the filter tank 1, the pressure inside the filter tank 1 squeezes the acrylic resin into each membrane filament of the ultrafiltration membrane 2, so that the filtered acrylic resin passes through the membrane filaments of the ultrafiltration membrane 2 into the collecting part 2001, and is then discharged from the discharge pipe 102 to the collecting device for collection, and the solid impurities filtered out of the acrylic resin are adsorbed to the outside of the membrane filaments of the ultrafiltration membrane 2.

[0031] When a lot of solid impurities are accumulated on the ultrafiltration membrane 2, resulting in a decrease in the filtration efficiency of the ultrafiltration membrane 2 for acrylic resin, the DD motor 103 is controlled to drive the gear 104 to rotate, thereby driving the gear ring 105 and the liquid inlet pipe 101 to rotate, and the two movable blocks 106 are moved toward the upper and lower parts of the filter tank 1 respectively through the two-way thread 10102 on the liquid inlet pipe 101, with the middle of the two-way thread 10102 as the boundary. The following is an explanation of the work of the movable block 106 and its related parts located at the top: the movable block 106 drives the scraper 3 through the elastic member 107 Move from the expansion part 1001 to the upper part of the filter tank 1. During this process, the protrusion 3001 is stuck in the first limiting groove 1002 and rises, limiting the scraper 3 to ensure that the movable block 106 rises normally when the liquid inlet pipe 101 rotates. During the rise of the scraper 3 in the expansion part 1001, the scraper 3 is gradually squeezed and moved toward the ultrafiltration membrane 2. At the same time, the elastic member 107 is compressed to combine several scrapers 3 into a ring shape. When the scraper 3 is squeezed and moved toward the ultrafiltration membrane 2, it drives the comber 6 to move toward the ultrafiltration membrane 2, so that the middle part of the ultrafiltration membrane 2 is changed from the expansion state to the state as shown in FIG. Figure 2In the vertical state shown, with the continuous rotation of the liquid inlet pipe 101, the movable block 106 drives the scraper 3 and the comber 6 to continue to rise. During the rising process, the impurities adsorbed on the membrane filaments of the ultrafiltration membrane 2 are scraped off to a loose state through the combing rod 6001, and the membrane filaments of the ultrafiltration membrane 2 are cleaned. At the same time, the impurities scraped off by the combing rod 6001 are blown out to the outside of the ultrafiltration membrane 2 through the acrylic resin sprayed from the upwardly inclined spray hole 10101, so that the impurities fall to the upper side of the scraper 3 for collection. In this process, the impurities falling to the upper side of the scraper 3 are intercepted by the blocking part 3002, thereby reducing the impurities detached from the upper side of the scraper 3 and improving the The impurity collection and cleaning effect is that during the rising process of the scraper 3, the outer side of the scraper 3 combined into a circular ring is fitted with the inner wall of the filter tank 1, and the impurities adhered to the inner wall of the filter tank 1 are scraped off to the upper side of the scraper 3 for collection. The acrylic resin on the upper side of the scraper 3 in the filter tank 1 is compressed during the rising process of the scraper 3, and flows to the lower side of the scraper 3 through the sieve holes 4001 on the filter tube 4. In this process, the large particles of solid impurities in the acrylic resin flowing through the filter tube 4 are intercepted by the sieve holes 4001, and the acrylic resin is filtered during the cleaning process of the ultrafiltration membrane 2, so that the large particles of solid impurities in the acrylic resin are intercepted to the upper side of the scraper 3.

[0032] When the scraper 3 drives the comber 6 to move to the lower side of the collecting part 2001, the comber 6 is blocked by the lower side of the collecting part 2001 and cannot continue to rise with the scraper 3, so that the comber 6 moves downward compared to the scraper 3, and the second elastic rope 7 is stretched at the same time. Then the scraper 3 continues to rise until it fits with the outer wall of the collecting part 2001. Due to the obstruction of the outer wall of the collecting part 2001, the acrylic resin on the upper side of the scraper 3 can only be discharged to the lower side of the scraper 3 through the filter tube 4. When the upper side of the filter tube 4 contacts the lower side of the partition 204, the control drive 203 drives the partition 204 to move upward. , so that the scraper 3 and the partition 204 rise together. The partition 204 compresses the internal space of the air cavity 1003 during the rising process. The air pressure inside the air cavity 1003 pushes the one-way air hole 20401 open and enters the space between the scraper 3 and the partition 204, pressurizing the space between the scraper 3 and the partition 204, and discharging the acrylic resin between the scraper 3 and the partition 204 through the filter tube 4 to the space under the scraper 3. When the acrylic resin between the scraper 3 and the partition 204 is discharged, the control driving member 203 drives the partition 204 to stop rising, and at the same time, the liquid inlet pipe 10 1 drives the scraper 3 to continue to rise, so that the distance between the scraper 3 and the partition 204 is shortened, so that the filter tube 4 is blocked by the partition 204 and moves downward on the scraper 3, and at the same time, the first elastic rope 5 is stretched to move the sieve hole 4001 downward to below the upper side of the scraper 3. When the stopper 4002 contacts the upper side of the scraper 3, the scraper 3 stops rising. At this time, the scraper 3 and the partition 204 are in a sealed state. At the same time, the water inlet pipe 201 and the drain pipe 202 are located between the scraper 3 and the partition 204. Then, the external water pump is controlled to transfer water from the water inlet pipe 201 to the space between the scraper 3 and the partition 204. During the cleaning process, the impurities collected on the scraper 3 are flushed, so that the water flow carries the impurities to the outside through the drain pipe 202, thereby preventing the impurities from continuously accumulating inside the filter tank 1, and preventing the ultrafiltration membrane 2 from being blocked by the accumulated impurities, thereby reducing the filtration efficiency of the acrylic resin, and even making it impossible to filter the acrylic resin normally. There is no need to backwash or replace the ultrafiltration membrane 2 in a short period of time, thereby extending the service life of the ultrafiltration membrane 2, and realizing the non-stop cleaning of impurities during normal filtration, thereby enhancing the filtration effect on the acrylic resin and improving the continuity of the acrylic resin filtration work.

[0033] When the impurities on the scraper 3 are cleaned, the DD motor 103 is controlled to make the gear 104 drive the gear ring 105 to rotate in the opposite direction, so that the liquid inlet pipe 101 rotates in the opposite direction, and then the movable block 106 drives the scraper 3 to descend in the filter tank 1. At the same time, the driving member 203 is controlled to drive the partition 204 to descend together with the scraper 3, so that the volume of the air cavity 1003 increases, and then the external gas enters the air cavity 1003 through the one-way air valve 1004 to replenish the gas in the air cavity 1003. When the scraper 3 descends to a position lower than the water inlet pipe 201, the partition 204 stops descending, and the scraper 3 continues to descend with the rotation of the liquid inlet pipe 101, so that the filter tube 4 rebounds and resets under the elastic force of the first elastic rope 5. , so that the upper and lower spaces of the scraper 3 are connected. During the descent of the scraper 3, the stretched second elastic rope 7 is gradually reset, so that the comber 6 rises and resets compared with the scraper 3. When the scraper 3 descends to pass the lower side of the collecting portion 2001, it drives the comber 6 to descend to the expansion portion 1001 for reset. When the scraper 3 moves to the expansion portion 1001, it contacts the inner wall of the expansion portion 1001 under the elastic force of the elastic member 107, driving the comber 6 to approach the inner wall of the filter tank 1, so that the combing rod 6001 drives the middle part of the membrane filament of the ultrafiltration membrane 2 to move toward the inner wall of the expansion portion 1001, so that the middle part of the ultrafiltration membrane 2 is expanded again to filter the acrylic resin, thereby ensuring the filtering effect of the ultrafiltration membrane 2 on the acrylic resin.

[0034] In summary, the movable block 106 and its related parts located at the bottom work in the same way as the movable block 106 and its related parts located at the top, and move synchronously in opposite directions to complete the cleaning of impurities adhering to the lower part of the ultrafiltration membrane 2.

[0035] Example 2 On the basis of Example 1, Figure 2 , Figure 4 and Figure 5 As shown, scraper strips 301 are also included; two scraper strips 301 are fixedly connected to the protruding portion 3001 of each scraper plate 3; and the scraper strips 301 are made of elastic deformable material.

[0036] When the scraper 3 is lowered to the expansion part 1001 in the filter tank 1 along with the movable block 106, the curved surface on the outside of the scraper 3 cannot fit with the inner wall of the expansion part 1001, and the impurities adhering to the inner wall of the expansion part 1001 cannot be cleaned, resulting in the accumulation of impurities on the inner wall of the expansion part 1001 for a long time, thus affecting the quality of the filtered acrylic resin. The specific solution process is as follows: The following is an explanation of the operation of the scraper 3 and the scraper strip 301 located above: when the scraper 3 is lowered to the expansion portion 1001 in the filter tank 1 along with the movable block 106, the scraper 3 contacts the inner wall of the expansion portion 1001 due to the elastic force of the elastic member 107, and at the same time drives the scraper strip 301 to contact the inner wall of the expansion portion 1001. At this time, the scraper strip 301 adheres to the inner wall of the expansion portion 1001 through its own elastic force. When the scraper 3 rises in the filter tank 1 along with the movable block 106 to clean the ultrafiltration membrane 2, the scraper strip 301 is driven to rise together with the scraper 3, and the scraper strip 301 adheres to the inner wall of the expansion portion 1001 to scrape off the impurities adhered to the inner wall of the expansion portion 1001, so that the impurities float in the filter tank 1, so that the scraper 3 can collect the impurities scraped off the inner wall of the expansion portion 1001 next time, so as to prevent the impurities from accumulating on the inner wall of the expansion portion 1001 for a long time, and to avoid the accumulated impurities affecting the quality of the filtered acrylic resin.

[0037] In summary, the scraper 3 and the scraper strip 301 located at the bottom work in the same manner as the scraper 3 and the scraper strip 301 located at the top, and move synchronously in opposite directions to complete the cleaning of impurities adhered to the inner wall of the expansion portion 1001.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
