Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-9 , a water treatment biofilm filtration device provided by the present utility model includes a bottom plate 1, a plurality of support plates 2 uniformly fixed on the top of the bottom plate 1, and a filtration component 4,

[0027] The filtration component 4 includes a biofilm reactor and a filtration medium. By using the filtration medium, that is, the biofilm, as a physical barrier, it can effectively intercept suspended solids, colloids, bacteria, some viruses and macromolecules in water, realizing a high degree of solid-liquid separation and achieving the effect of purifying water quality;

[0028] A plurality of support plates 2 are fixedly inserted with multiple groups of metal water pipes 3, and symmetrically distributed threaded pipes 5 are fixed on the side walls opposite to the water outlets of a group of metal water pipes 3. A metal ring 6 is fixed at the bottom of the threaded pipe 5, and an adjusting mechanism is provided on the metal ring 6. The threaded pipe 5 is connected with a rubber pad 7 through the adjusting mechanism, and the filtering component 4 is clamped between two rubber pads 7. When the upper and lower ends of the filtering component 4 are placed between the two rubber pads 7, both ends of the filtering component 4 will squeeze the first spring 15, causing the rubber pad 7 to move upward to the bottom of the metal ring 6, closely fitting to form a seal, and being able to clamp and fix the filtering component 4;

[0029] An installation ring 8 is sleeved on the side wall of the threaded pipe 5, and a rubber cylinder 9 is fixed on the side wall of the installation ring 8. The rubber cylinder 9 can closely fit with the side walls of the metal ring 6 and the reactor of the filtering component 4 to form a seal;

[0030] A guiding mechanism is provided at the bottom of the installation ring 8, and the installation ring 8 is connected with a sealing plate 10 through the guiding mechanism. Symmetrically distributed clamping mechanisms are provided on the side wall of the rubber cylinder 9, and the clamping mechanisms can respectively form a clamping connection with the metal ring and the filtering component, facilitating the stability of the device;

[0031] The guiding mechanism includes two sliding grooves 1103 symmetrically opened at the bottom of the metal ring 6, and a connecting rod 1102 is inserted in the sliding groove 1103. A guiding rod 1101 is inserted through the metal ring 6, and the top end of the guiding rod 1101 is fixed at the bottom of the installation ring 8. Both ends of the connecting rod 1102 are respectively fixed on the opposite side walls of the sealing plate 10 and the guiding rod 1101. When the sliding groove 1103 can rise on the connecting rod 1102, it can be received into the sliding groove 1103, allowing the sealing plate 10 to enter the threaded pipe 5 to form a seal;

[0032] The adjusting mechanism includes a threaded ring 1401 screwed with the threaded pipe 5, and an annular groove 1402 is opened at the bottom of the threaded ring 1401. Four uniformly distributed installation grooves 1406 are opened at the bottom of the metal ring 6, and circular plates 1405 are inserted in the four installation grooves 1406. Four uniformly distributed sliders 1403 are inserted in the annular groove 1402. Four uniformly distributed connecting rods 1404 are inserted through the installation ring 8, and both ends of the connecting rod 1404 are respectively fixed on the opposite side walls of the circular plate 1405 and the slider 1403. The circular plate 1405 is connected with the rubber pad 7 through a first telescopic mechanism. By rotating the threaded ring 1401 screwed with the threaded pipe 5, the connecting rod 1404 and the circular plate 1405 are driven to move downward to squeeze the first spring 15, making the clamping of the filtering component 4 more stable;

[0033] The first telescopic mechanism includes a first spring 15 inserted in the installation groove 1406, and both ends of the first spring 15 are respectively fixed on the opposite side walls of the rubber pad 7 and the circular plate 1405. The first spring 15 can provide a pre-tightening force to make the clamping more stable;

[0034] The snap - connection mechanism includes two mounting holes 1201 symmetrically opened on the side wall of the rubber cylinder 9. A limiting rod 1202 is inserted into the mounting hole 1201. A limiting plate 1203 is fixed at the end of the limiting rod 1202, and the limiting plate 1203 is connected to the rubber cylinder 9 through a second telescopic mechanism. Symmetrically - distributed limiting grooves 1204 are opened on the side wall of the metal ring 6, and the limiting grooves 1204 are adapted to the limiting rod 1202. Inserting the limiting rod 1202 into the limiting grooves 1204 on the side wall of the metal ring 6 can make the sealing plate 10 seal the threaded pipe 5 and prevent water flow from flowing out of the threaded pipe 5.

[0035] The second telescopic mechanism includes a second spring 13 sleeved on the side wall of the limiting rod 1202. The two ends of the second spring 13 are respectively fixed on the opposite side walls of the limiting plate 1203 and the rubber cylinder 9. By the action of the elastic force of the second spring 13, the limiting rod 1202 can be inserted into the circular grooves opened on the side wall of the reactor of the filter assembly 4 and the limiting grooves 1204 on the side wall of the metal ring 6 respectively to form a snap - connection and fixation.

[0036] Working principle: During use, place the upper and lower ends of the filter assembly 4 between two rubber pads 7. The two ends of the filter assembly 4 will squeeze the first spring 15, causing the rubber pads 7 to move up to the bottom of the metal ring 6, closely fitting to form a seal and being able to clamp and fix the filter assembly 4. If it is found that the clamping of the used filter assembly 4 is not firm enough, the threaded ring 1401 screwed to the threaded pipe 5 can be rotated to drive the connecting rod 1404 and the circular plate 1405 to move down to squeeze the first spring 15, making the clamping of the filter assembly 4 more firm.

[0037] When the filter assembly 4 is clamped stably, due to the action of the elastic force of the second spring 13, inserting the limiting rod 1202 into the limiting grooves 1204 on the side wall of the metal ring 6 can make the sealing plate 10 seal the threaded pipe 5 and prevent water flow from flowing out of the threaded pipe 5. When the installation ring 8 is pushed to drive the guide rod 1101 and the connecting rod 1102 to move down, making the sealing plate 10 move out of the inner opening of the threaded pipe 5, water flow can flow out of the metal water pipe 3 and then be introduced into the filter assembly 4 for filtration. And when the installation ring 8 moves down to the moving position, under the action of the elastic force of the second spring 13, the limiting rod 1202 will be inserted into the circular grooves opened on the side wall of the reactor of the filter assembly 4 to form a snap - connection and fixation.
