Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for intercepting backwash wastewater from fructose production resin. Background Technology

[0002] In the industrial production of fructose, especially in the manufacturing process of high fructose syrup, ion exchange resins and molecular sieve resins are widely used in key processes such as decolorization, desalination, impurity removal, and separation and purification of fructose and glucose. During long-term operation, organic matter, colloids, metal ions, and microparticle impurities gradually accumulate on the surface and pores of these resins, leading to resin bed blockage, decreased mass transfer efficiency, and reduced separation performance, which in turn affects product quality and production efficiency.

[0003] To restore the activity and separation capacity of the resin, the resin bed must be backwashed regularly. The backwashing process usually involves water or a specific cleaning solution flowing counter-currently from bottom to top through the resin bed, which loosens and expands the resin particles and flushes out the trapped suspended solids, broken resin particles and other impurities from the system, forming resin backwash wastewater.

[0004] However, this backwash wastewater contains a large number of broken resin particles. Direct discharge can easily cause blockages in pipes and sewage treatment facilities. Most fructose production companies treat resin backwash wastewater in a rather crude manner, often discharging it directly into the sewage treatment plant to be mixed with other production wastewater. This practice greatly increases the load and operating costs of the sewage treatment system. Using conventional resin capture tanks for interception is also problematic, as the horizontally set filter screens are easily clogged by the accumulation of broken resin, requiring frequent shutdowns for cleaning. This cannot meet the needs of continuous production, and the cleaning operation requires climbing into the tank, which is difficult. Utility Model Content

[0005] In view of this, this utility model proposes a fructose production resin backwashing wastewater interception device, which can efficiently intercept broken resin, has a good anti-clogging effect, extends the maintenance cycle, and is convenient to clean.

[0006] The technical solution of this utility model is achieved as follows: This utility model provides a fructose production resin backwash wastewater interception device, including a resin capture tank and a filter screen, wherein,

[0007] The resin capture tank includes a tank body, an inlet, and an outlet. The inlet is fixedly located at one end of the tank body, and the outlet is fixedly located at the other end of the tank body. The outlet and the inlet are staggered, and the height of the outlet is lower than the height of the inlet.

[0008] The filter screen is fixedly installed inside the tank and is inclined, with the water inlet located below the filter screen and the water outlet located above the filter screen.

[0009] Based on the above technical solutions, preferably, the tilt angle of the filter screen is 30 degrees to 45 degrees.

[0010] Preferably, the filter screen is tilted at an angle of 35 degrees.

[0011] Preferably, the resin trap further includes observation windows, which are fixedly mounted on the tank body. There are three observation windows, one of which is located above the filter screen, and the other two are located below the filter screen.

[0012] Preferably, the resin trap further includes a cleaning port, which is fixedly disposed at the lower part of the tank body.

[0013] More preferably, the system also includes a cleaning mechanism comprising a support rod, a side scraper, a connecting plate, a main scraper, and a hook plate. The support rod is fixedly mounted on the inner walls of both ends of the bottom side of the tank. One end of the side scraper is rotatably mounted on the support rod, and the bottom side of the side scraper abuts against the tank. The connecting plate is rotatably mounted on the other end of the side scraper, and the bottom side of the connecting plate abuts against the tank. The main scraper is located at the end of the tank away from the cleaning port, and both ends of the main scraper are slidably connected to the connecting plate, and the bottom side of the main scraper abuts against the tank. The hook plate is fixedly mounted on the main scraper.

[0014] More preferably, the connecting plate includes a plate body and a connecting shaft, the connecting shaft is fixedly disposed at both ends of the plate body, and the connecting shaft at both ends of the plate body is rotatably connected to the side scraper and the main scraper, respectively.

[0015] Based on the above technical solutions, preferably, the main scraper is provided with grooves at both ends, and the connecting shaft at one end of the plate body is inserted into the groove and slidably connected thereto.

[0018] The fructose production resin backwashing wastewater interception device of this utility model has the following advantages over the prior art:

[0019] (1) By setting the filter screen at an angle inside the tank, with the inlet below the filter screen and the outlet above the filter screen, the wastewater entering the tank is forced to pass through the filter screen for filtration, ensuring that only filtered clean water comes out of the outlet. The angled setting increases the filtration area of ​​the filter screen, improves filtration efficiency, and allows the broken resin on the filter screen to slide down the slope into the bottom of the tank during filtration, preventing the broken resin from accumulating on the filter screen and extending the maintenance cycle.

[0020] (2) By setting up a cleaning device, the main scraper drives the two side scrapers to rotate through the connecting plate.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figure 1-6 As shown, the present invention provides a fructose production resin backwashing wastewater interception device, comprising a resin capture tank 1, a filter screen 2, a cleaning mechanism 3, and a scraper 4.

[0032] The resin capture tank 1 provides a treatment space for the filtration of backwash wastewater. The resin capture tank 1 includes a tank body 11, an inlet 12, and an outlet 13. The inlet 12 is fixedly located at one end of the tank body 11, and the wastewater enters the tank body 11 through the inlet 12. The outlet 13 is fixedly located at the other end of the tank body 11 and is used to discharge the filtered clean water. The outlet 13 and the inlet 12 are staggered, and the height of the outlet 13 is lower than the height of the inlet 12, so that a height difference is formed between the outlet 13 and the inlet 12, which prolongs the water flow path.

[0033] The filter screen 2 is used to intercept resin fragments in the wastewater. The filter screen 2 is fixedly installed inside the tank 11 and is inclined at an angle of 30 to 45 degrees. The inlet 12 is located below the filter screen 2, and the outlet 13 is located above the filter screen 2, so that the wastewater entering the tank 11 is forced to pass through the filter screen 2 for filtration. This ensures that only filtered clean water exits from the outlet 13. The inclined design increases the filtration area of ​​the filter screen 2, improves the filtration efficiency, and allows the intercepted material on the filter screen 2 to slide down the slope into the bottom of the tank 11 during filtration, preventing resin fragments from accumulating on the filter screen 2. This achieves gravity self-cleaning and extends the maintenance cycle.

[0034] To improve the filtration effect, the tilt angle of filter screen 2 is preferably 35 degrees, which also makes it less prone to clogging.

[0035] To facilitate the observation of the filtration status of the filter screen 2 inside the resin capture tank 1, the resin capture tank 1 also includes an observation window 14. The observation window 14 is fixedly installed on the tank body 11. There are three observation windows 14, one of which is located above the filter screen 2, and the other two are located below the filter screen 2. This makes it easy to observe the interception status and clogging status of the filter screen 2, ensuring the normal operation of the device. At the same time, it allows for the observation of the accumulation of broken resin at the bottom of the resin capture tank 1, facilitating its cleaning.

[0036] To facilitate the cleaning of the resin fragments intercepted inside the resin capture tank 1, the resin capture tank 1 also includes a cleaning port 15. The cleaning port 15 is fixedly located at the lower part of the tank body 11. Workers can enter the resin capture tank 1 through the cleaning port 15 to clean its interior. To ensure the airtightness of the resin capture tank 1, a sealing cover is provided at the cleaning port 15. After the sealing cover is closed, the cleaning port 15 is sealed to prevent leakage.

[0037] The cleaning mechanism 3 is used to clean the bottom wall of the tank 11. The cleaning mechanism 3 includes a support rod 31, a side scraper 32, a connecting plate 33, a main scraper 34, and a hook plate 35. The support rod 31 is fixedly installed on the inner wall of both ends of the bottom side of the tank 11. One end of the side scraper 32 is rotatably mounted on the support rod 31, and the bottom side of the side scraper 32 abuts against the tank 11. During rotation, the side scraper 32 scrapes the broken resin deposited at the bottom of the tank 11 to the cleaning port 15, which plays a role in aggregating the broken resin and facilitating the cleaning operation. The connecting plate 33 is rotatably mounted on the other end of the side scraper 32, and the bottom side of the connecting plate 33 is flush with the tank 11. The main scraper 34 is located inside the tank 11 at the end away from the cleaning port 15, and both ends of the main scraper 34 are slidably connected to the connecting plate 33. The bottom side of the main scraper 34 is in contact with the tank 11. The main scraper 34 drives the side scrapers 32 to move through the connecting plates 33 at both ends. The main scraper 34 and the connecting plate 33 clean the areas that the two side scrapers 32 cannot reach, increasing the cleaning range and reducing cleaning dead corners. The hook plate 35 is fixedly installed on the main scraper 34, providing a hooking position. A long hook can be used to hook the hook plate 35 to drive the main scraper 34 to move. The operator does not need to go deep into the tank 11 to operate.

[0038] The connecting plate 33 includes a plate body 331 and a connecting shaft 332. The connecting shaft 332 is fixedly installed at both ends of the plate body 331, and the connecting shaft 332 at both ends of the plate body 331 is rotatably connected to the side scraper 32 and the main scraper 34 respectively, connecting the two side scrapers 32 and the main scraper 34 into one unit, thereby realizing the synchronous rotation of the two side scrapers 32.

[0039] To ensure that the two side scrapers 32 scrape the material normally, the two ends of the main scraper 34 are provided with grooves 301. The connecting shaft 332 at one end of the plate body 331 is inserted into the groove 301 and slidably connected to it. As the two side scrapers 32 gradually come together, the distance between the two side scrapers 32 gradually decreases. The connecting plate 33 can adjust the overall length by sliding in the groove 301 through the connecting shaft 332, so that the scraping can be carried out smoothly.

[0040] The scraper 4 is used to improve the adhesion to the bottom of the tank 11. The scraper 4 includes a main fixing plate 41, a side fixing plate 42, and a rubber strip 43. The main fixing plate 41 is fixedly mounted on the main scraper 34; the side fixing plate 42 is fixedly mounted on the side scraper 32. Both the main fixing plate 41 and the side fixing plate 42 are used to fix the rubber strip 43. The rubber strip 43 is fixedly mounted on the main fixing plate 41 and the side fixing plate 42, which facilitates the installation and fixation of the rubber strip 43 and improves the structural strength of the rubber strip 43. The rubber strip 43 is elastic and has a high degree of adhesion, which can tightly adhere to the bottom of the tank 11 and effectively scrape off the broken resin adhering to the bottom of the tank 11, thereby improving cleaning efficiency and cleaning effect.

[0041] To improve the scraping effect of the rubber strip 43, the main fixing plate 41 is set on the main scraper 34 at one end near the cleaning port 15, and both ends of the main fixing plate 41 are inclined to avoid the two ends of the main fixing plate 41 being obstructed by the connecting plate 33 and the side scraper 32 when moving. At the same time, it can gather the material at both ends towards the middle position during the scraping process, which has the effect of material collection. The side fixing plate 42 is fixedly set at the end of the side scraper 32 away from the cleaning port 15, and the length of the side fixing plate 42 is greater than the length of the side scraper 32. The end of the side fixing plate 42 near the connecting plate 33 extends out of the side scraper 32, extending the length of the side fixing plate 42, increasing the coverage area of ​​the rubber strip 43, reducing cleaning dead corners, and improving the scraping effect.

[0042] The method of using the fructose production resin backwashing wastewater interception device of this utility model is as follows:

[0043] Wastewater generated during backwashing enters tank 11 through inlet 12. The wastewater impacts filter screen 2, which intercepts resin fragments. Due to the inclined design of filter screen 2, the resin fragments trapped on it slide down the slope under their own weight and fall to the bottom of tank 11, reducing clogging and extending maintenance intervals. After being filtered by filter screen 2, the wastewater is discharged from tank 11 through outlet 13. When there is a lot of resin debris at the bottom of the tank 11, close the inlet 12 to stop water intake. After some water is drained from the tank 11, open the cleaning port 15 to continue draining water. After the drainage is complete, clean the inside of the tank 11. Use a long hook to hook the hook plate 35 and pull it towards the cleaning port 15. The main scraper 34 drives the side scraper 32 to rotate through the connecting plate 33, scraping the dirt away from the cleaning port 15 towards the cleaning port 15. The staff does not need to go deep into the tank 11 to perform cleaning operations, which is convenient and quick.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
