Description

Technical Field

[0001] The utility model belongs to the technical field of tube ice machine filtration, in particular to a filtration device for a tube ice machine. Background Art

[0002] The filtration device of the tube ice machine includes a quartz sand filter, an activated carbon filter and a softening water filter. The quartz sand filter can effectively intercept and remove suspended matter, organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions in the water, reduce the turbidity of the water, and provide basic water quality assurance for subsequent treatment; the activated carbon filter can adsorb free chlorine, organic matter, colloids, pigments, heavy metal ions, etc. in the water, and can also reduce COD, effectively remove impurities remaining in the front-stage filtration, prevent oxidative degradation and other pollution to the rear-stage reverse osmosis membrane, and further improve water quality; the softening water filter is mainly used to reduce the hardness of the water, remove calcium, magnesium and other ions in the water, and prevent scale from being generated during the operation of the tube ice machine due to excessively hard water quality, which affects the normal operation of the equipment and the quality of the tube ice, thereby extending the service life of the equipment and ensuring the efficient and stable operation of the tube ice machine.

[0003] The filtration principle of sand filters is to intercept impurities in the water through the pores of the sand layer. When mud and large particles of impurities gradually accumulate in the sand filter, they will first block the pores of the sand layer. After the pores are blocked, the resistance of water passing through the sand filter will increase significantly, causing the water flow rate to slow down. It is like a smooth road. When there are many obstacles, the speed of vehicles (water flow) will decrease. Moreover, as the impurities increase, the effective space of the sand filter for intercepting new impurities will decrease. The space that originally allowed water to fully contact with the sand layer and for impurities to be effectively adsorbed and intercepted is occupied by existing impurities. This is like a filter. When it is full of garbage, it is difficult to filter new impurities, which greatly reduces the filtration effect. In this case, the sand filter not only fails to effectively remove impurities in the water, but may also cause the water quality to deteriorate, because the trapped impurities may be released back into the water, or cause bacteria and other harmful microorganisms to grow in the water.

[0004] Therefore, under normal circumstances, the quartz sand filter needs to be disassembled, cleaned or replaced regularly. This is because if the quartz sand filter is not provided with a large-particle filtering structure, a large amount of large-particle impurities will directly enter the quartz sand filter during the filtration process, causing the quartz sand filter to be quickly clogged by impurities, greatly affecting its filtration efficiency. In this case, the quartz sand filter needs to be cleaned or replaced frequently, which not only increases maintenance costs but also affects the normal operation of the equipment. Most of the existing filters are not provided with a corresponding impurity filtering structure, which makes it inconvenient to pre-filter large-particle impurities in the water as a whole. Without a pre-filtering structure, large-particle impurities will directly enter the filter body, accelerating the clogging and damage of the filter. At the same time, the existing filters are not convenient for quickly disassembling and assembling the corresponding filtering structure. When maintenance and cleaning are required, the cumbersome disassembly and assembly process will consume a lot of time and manpower, reducing work efficiency. This results in the filter requiring frequent maintenance and cleaning during use, which brings great inconvenience to users. Utility Model Content

When the filter assembly 93 needs to be cleaned or maintained, the sealing plate 934 can be easily removed by manually twisting the hand-tightening screw, and then the filter frame 932 can be taken out for processing. The anti-slip protrusions fixed at equal intervals on the outer surface of the knob at the outer end of the fixed screw 937 increase the friction between the hand and the screw, prevent slipping during operation, and make the operation more stable and reliable. This design improves the practicality and convenience of the filter device and provides a strong guarantee for the stable operation of the tube ice machine.

[0027] Principle and advantages of use: By setting up the filtering mechanism 9, the device can show excellent performance during use. Specifically, the water pump 3 can be started. At this time, the water pump 3 can be operated to pump water and transport the water to the bottom of the filter box 91 through the connecting pipe 8. The water flows from bottom to top in the filter box 91, and is first filtered through the filter mesh 933 to remove large particles of impurities in the water. Subsequently, the filtered water enters the quartz sand filter 5, the activated carbon filter 6 and the softening water filter 7 through the connecting pipe 8. These filters further assist in deep filtration of the water. Before the water enters the quartz sand filter 5, the activated carbon filter 6 and the softening water filter 7 are filtered. Before the filtration, the filter screen 933 plays an important role in pre-filtration, which can effectively reduce the large particles of impurities entering the quartz sand filter 5 and prevent the quartz sand filter 5 from being blocked by too many impurities. In the filtration process, since the water flows from bottom to top, the filtered impurities will flow into the interior of the collection bucket 939. When cleaning is needed, the interior of the collection bucket 939 can be easily cleaned by twisting the sealing cover 938, making the entire device extremely convenient to use. Pre-treatment of the water can greatly prevent the quartz sand filter 5 from being blocked by too many impurities, thereby ensuring the stable operation of the filtration system.

[0028] By setting up the filtering mechanism 9, the performance of the device during use is more outstanding. During use, the flow of water can drive the turbine 9362 to rotate, and the rotation of the turbine 9362 can drive the rotation of the rotating shaft 9361, and the rotation of the rotating shaft 9361 can drive the brush plate 9363 to rotate. The rotation of the brush plate 9363 can clean the bottom of the filter 933. It can be seen that during use, once the water supply is started, the water flow can automatically drive the brush plate 9363 to rotate and rub the cleaning brush, which can effectively avoid the filter 933 from being blocked. Moreover, if necessary, When cleaning the filter 933, it is only necessary to loosen the hand-tightening fixing bolts and move them outward. At this time, the sealing plate 934 can be removed from the slot 931, and then the filter frame 932 and the filter 933 inside it can be pulled out. This design enables the device as a whole to have an automatic cleaning function, and is also convenient for quick disassembly and cleaning. These advantages of the device as a whole can improve its filtering protection performance during use. The easy-to-clean design facilitates reuse, can minimize the replacement frequency of the quartz sand filter 5, improve its overall convenience of use, and reduce the cost of use.
