DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1, with reference to Figure 1-3 A degassing and filtering device for a water purifier includes a filter box 2 with a water outlet at the bottom. An annular ring 17 is fixed in the middle of the filter box 2, and a high-elasticity filter membrane 16 is fixed on the upper part of the annular ring 17. Activated carbon particles are placed on the upper end of the high-elasticity filter membrane 16. A first telescopic rod 3 is connected to the middle of the upper end of the high-elasticity filter membrane 16, and the first telescopic rod 3 is fixed to the inner upper end of the filter box 2 through a connecting frame 5.

[0027] A number of exchange holes 15 are evenly arranged in the middle of the filter box 2 at the upper end of the annular ring 17. A storage box 4 is movably arranged outside the filter box 2. Both sides of the storage box 4 are connected with connecting pipes 14. A sealing gasket is provided on the side where the storage box 4 is in contact with the filter box 2, and a material hole matching the exchange hole 15 is provided on one side of the storage box 4.

[0028] A support frame 1 is provided at the upper end of the outer side of the filter box 2, and a plurality of second telescopic rods 6 are provided between the support frame 1 and the storage box 4. The position height of the storage box 4 is adjusted by adjusting the length of the second telescopic rods 6. A connecting piece 9 is provided at the top position inside the storage box 4, and a gear ring 10 is connected through the connecting piece 9. A motor 7 is installed on the storage box 4, and a transmission gear 8 is connected to the end of the output shaft of the motor 7. The transmission gear 8 and the gear ring 10 are engaged with each other. A number of baffles 11 are evenly installed on the lower end of the gear ring 10, and the bottom of the storage box 4 is tilted downward toward the side close to the filter box 2, and a through-type notch 12 is opened horizontally on the upper side of the baffle 11.

[0029] Degassing and filtration consists of two steps: degassing and filtration. There is hydrogen sulfide gas in the water body. In the process of water being transported to the filter box 2 through a pipeline, ozone is added into the transport pipeline to remove the hydrogen sulfide gas in the water. Other substances produced are treated in subsequent steps, and other substances can also be used to treat the hydrogen sulfide gas in the water.

[0030] When the water to be treated is transported to the inside of the filter box 2 by the pipeline, the water will pass through the accumulated activated carbon particles and the high-elasticity filter membrane 16 below to treat the impurities in the water. At this time, the storage box 4 will block the exchange hole 15. At the same time, the sealing gasket on one side of the storage box 4 and the outer wall of the filter box 2 are squeezed and sealed to block the exchange hole 15. After a period of filtration, some water areas contain high levels of calcium carbonate and silica scale, so that the outside of the activated carbon particles will be quickly surrounded by scale. After the activated carbon particles are blocked, their ability to adsorb colloidal impurities in the water will decrease, resulting in a problem of reduced filtration effect.

[0031] To this end, turn on the power of the first telescopic rod 3 and lift the high-elasticity filter membrane 16 upward. Since the connection point between the first telescopic rod 3 and the high-elasticity filter membrane 16 is located in the middle position, the high-elasticity filter membrane 16 is tapered. At this time, adjust the length of the second telescopic rod 6 and lower the position height of the storage box 4 downward until the material port on one side of the storage box 4 is connected to the exchange hole 15. During this process, the activated carbon particles inside the filter box 2 will continue to enter the storage box 4. After most of the activated carbon particles are transferred to the inside of the storage box 4, an agent capable of removing scale is transported to the inside of the storage box 4 through one of the connecting pipes 14. An acidic agent can be selected. While the activated carbon particles are immersed in the agent, start the motor 7. The motor 7 drives the gear ring 1 through the transmission gear 8 below. 0 realizes rotation. During the rotation of the gear ring 10, the T-shaped slider 92 fixed by the connecting column 93 at the upper end of the gear ring 10 slides in the T-shaped slide rail 91 at the top. The structure realizes the suspension and support effect of the gear ring 10, and keeps the gear ring 10 and the transmission gear 8 always in meshing relationship. When the gear ring 10 rotates, the baffle 11 at its lower end drives the conical seat 13 connected to the bottom to move between the activated carbon particles, so that it can fully achieve the stirring effect and turn the activated carbon particles over. At the same time, the activated carbon particles can exchange positions from both sides of the baffle 11, ensuring that the originally accumulated activated carbon particles can completely contact with the reagent. In the process of contact between the conical seat 13 and the activated carbon particles, it can also help to quickly remove the scale that is about to fall off.

[0032] When the activated carbon particles are in full contact with the reagent, the reagent is discharged through the original connecting tube 14, and water is injected into the storage box 4 through another connecting tube 14. During this process, the conical seat 13 still keeps rotating to wash away the reagent adhering to the activated carbon particles. The water is repeatedly pumped out and injected for cleaning to keep the activated carbon particles in a stable state.

[0033] When cleaning is completed, the water in the storage box 4 is drained, and stirring is continued to dry the activated carbon particles. When drying is completed, the high-elasticity filter membrane 16 is pressed downward by adjusting the length of the first telescopic rod 3, and the middle part is concave. At this time, the length of the second telescopic rod 6 is adjusted again to make the position height of the storage box 4 rise until the lowest point of the bottom of the storage box 4 is flush with the lower end of the exchange hole 15. As the conical seat 13 continues to rotate, the activated carbon particles in the storage box 4 will pass through the exchange hole 15 and return to the upper part of the high-elasticity filter membrane 16. After the activated carbon particles are completely transferred, the storage box 4 is lifted to its initial position again to block the exchange hole 15. At the same time, the first telescopic rod 3 is adjusted to restore to its initial length to keep the high-elasticity filter membrane 16 in a horizontal state.

[0034] Example 2, reference Figure 4 The difference between this embodiment and embodiment 1 is that a conical seat 13 is installed at the bottom of the baffle 11, the middle part of the upper end of the conical seat 13 is recessed downward, and a water inlet groove 18 is symmetrically provided on the upper part of the conical seat 13. A cavity 24 is provided inside the conical seat 13, and through-type leakage holes 19 are opened on both sides of the conical seat 13. A plurality of dust-absorbing cotton cloths 21 are staggered inside the cavity 24. The surface of the dust-absorbing cotton cloths 21 is wrinkled, and the dust-absorbing cotton cloths 21 are located between the water inlet groove 18 and the leakage hole 19 on the same side.

[0035] When the activated carbon particles are constantly stirred in the storage box 4, the friction between the particles will cause some activated carbon powder to appear. At this time, two water inlet grooves 18 are symmetrically arranged in the depression at the upper end of the conical seat 13. Water, powder and other small impurity particles enter the cavity 24 inside the conical seat 13 through the water inlet grooves 18 along the upper end inclined surface of the conical seat 13. Multiple dust-absorbing cotton cloths 21 are arranged in the cavity 24, and when the powder and water pass through the dust-absorbing cotton cloths 21 and are discharged from the leakage hole 19, the powder will adhere to the dust-absorbing cotton cloths 21, and the surface of the dust-absorbing cotton cloths 21 is wrinkled, which can increase the space for absorbing the powder.

[0036] Example 3, reference Figure 5-7 The difference between this embodiment and embodiment 1 is that a regulating component 20 is further provided on the upper part of the water inlet trough 18, and the regulating component 20 includes a slot hole 201, a limiting plate 202, a through hole 203, a floating plate 204 and a guide rod 205.

[0037] The slot hole 201 is opened at the bottom position of one side of the baffle 11, the guide rod 205 is symmetrically arranged at the positions at both ends of the water inlet groove 18, the floating plate 204 is arranged in an arc shape in vertical cross section, and the through hole 203 is opened at one end of the floating plate 204. The guide rod 205 passes through the inner side of the through hole 203, and a limit plate 202 is fixedly installed at the top position of the guide rod 205. The diameter of the limit plate 202 is larger than the diameter of the guide rod 205. When the floating plate 204 moves up and down, one side of the floating plate 204 is located on the inner side of the slot hole 201.

[0038] Scrapers 22 are vertically installed at the four corners of the lower end of the floating plate 204, and the lower end of the scraper 22 is set at a pointed end. The bottom of the scraper 22 is provided with a tooth groove 23, and the position of the tooth groove 23 matches the four corners of the water inlet trough 18.

[0039] When the activated carbon is dried, that is, the water in the storage box 4 has been drained, in the water-free state, the colloid position originally existing between the particles will enter the water inlet trough 18 along the upper end surface of the conical seat 13. Since the colloid has poor fluidity in the water-free state, it adheres to the water inlet trough 18, especially the inner corner of the water inlet trough 18. Therefore, in the water state, the position of the float 204 will be lifted up, so that a gap will appear between the water inlet trough 18 and the float 204 for powder to enter. When it is in the sewage state, the float 204 falls to block the water inlet trough 18 and prevent a large amount of colloid from entering. Secondly, in the process of the float 204 falling, the scraper 22 and the tooth groove 23 connected to the bottom thereof can just clean the impurities located at the inner corner of the water inlet trough 18, thereby avoiding the problem of clogging of the water inlet trough 18.

[0040] The working principle of the device is: Degassing and filtration consists of two steps: degassing and filtration. There is hydrogen sulfide gas in the water body. In the process of water being transported to the filter box 2 through a pipeline, ozone is added into the transport pipeline to remove the hydrogen sulfide gas in the water. Other substances produced are treated in subsequent steps, and other substances can also be used to treat the hydrogen sulfide gas in the water.

[0041] When the water to be treated is transported to the inside of the filter box 2 by the pipeline, the water will pass through the accumulated activated carbon particles and the high-elasticity filter membrane 16 below to treat the impurities in the water. At this time, the storage box 4 will block the exchange hole 15. At the same time, the sealing gasket on one side of the storage box 4 and the outer wall of the filter box 2 are squeezed and sealed to block the exchange hole 15. After a period of filtration, some water areas contain high levels of calcium carbonate and silica scale, so that the outside of the activated carbon particles will be quickly surrounded by scale. After the activated carbon particles are blocked, their ability to adsorb colloidal impurities in the water will decrease, resulting in a problem of reduced filtration effect.

[0042] To this end, turn on the power of the first telescopic rod 3 and lift the high-elasticity filter membrane 16 upward. Since the connection point between the first telescopic rod 3 and the high-elasticity filter membrane 16 is located in the middle position, the high-elasticity filter membrane 16 is tapered. At this time, adjust the length of the second telescopic rod 6 and lower the position height of the storage box 4 downward until the material port on one side of the storage box 4 is connected to the exchange hole 15. During this process, the activated carbon particles inside the filter box 2 will continue to enter the storage box 4. After most of the activated carbon particles are transferred to the inside of the storage box 4, an agent capable of removing scale is transported to the inside of the storage box 4 through one of the connecting pipes 14. An acidic agent can be selected. While the activated carbon particles are immersed in the agent, start the motor 7. The motor 7 drives the gear ring 1 through the transmission gear 8 below. 0 realizes rotation. During the rotation of the gear ring 10, the T-shaped slider 92 fixed by the connecting column 93 at the upper end of the gear ring 10 slides in the T-shaped slide rail 91 at the top. The structure realizes the suspension and support effect of the gear ring 10, and keeps the gear ring 10 and the transmission gear 8 always in meshing relationship. When the gear ring 10 rotates, the baffle 11 at its lower end drives the conical seat 13 connected to the bottom to move between the activated carbon particles, so that it can fully achieve the stirring effect and turn the activated carbon particles over. At the same time, the activated carbon particles can exchange positions from both sides of the baffle 11, ensuring that the originally accumulated activated carbon particles can completely contact with the reagent. In the process of contact between the conical seat 13 and the activated carbon particles, it can also help to quickly remove the scale that is about to fall off.

[0043] When the activated carbon particles are in full contact with the reagent, the reagent is discharged through the original connecting tube 14, and water is injected into the storage box 4 through another connecting tube 14. During this process, the conical seat 13 still keeps rotating to wash away the reagent adhering to the activated carbon particles. The water is repeatedly pumped out and injected for cleaning to keep the activated carbon particles in a stable state.

[0044] When cleaning is completed, the water in the storage box 4 is drained, and stirring is continued to dry the activated carbon particles. When drying is completed, the high-elasticity filter membrane 16 is pressed downward by adjusting the length of the first telescopic rod 3, and the middle part is concave. At this time, the length of the second telescopic rod 6 is adjusted again to make the position height of the storage box 4 rise until the lowest point of the bottom of the storage box 4 is flush with the lower end of the exchange hole 15. As the conical seat 13 continues to rotate, the activated carbon particles in the storage box 4 will pass through the exchange hole 15 and return to the upper part of the high-elasticity filter membrane 16. After the activated carbon particles are completely transferred, the storage box 4 is lifted to its initial position again to block the exchange hole 15. At the same time, the first telescopic rod 3 is adjusted to restore to its initial length to keep the high-elasticity filter membrane 16 in a horizontal state.

[0045] When the activated carbon particles are constantly stirred in the storage box 4, the friction between the particles will cause some activated carbon powder to appear. At this time, two water inlet grooves 18 are symmetrically arranged in the depression at the upper end of the conical seat 13. Water, powder and other small impurity particles enter the cavity 24 inside the conical seat 13 through the water inlet grooves 18 along the upper end inclined surface of the conical seat 13. Multiple dust-absorbing cotton cloths 21 are arranged in the cavity 24, and when the powder and water pass through the dust-absorbing cotton cloths 21 and are discharged from the leakage hole 19, the powder will adhere to the dust-absorbing cotton cloths 21, and the surface of the dust-absorbing cotton cloths 21 is wrinkled, which can increase the space for absorbing the powder.

[0046] When the activated carbon is dried, that is, the water in the storage box 4 has been drained, in the water-free state, the colloid position originally existing between the particles will enter the water inlet trough 18 along the upper end surface of the conical seat 13. Since the colloid has poor fluidity in the water-free state, it adheres to the water inlet trough 18, especially the inner corner of the water inlet trough 18. Therefore, in the water state, the position of the float 204 will be lifted up, so that a gap will appear between the water inlet trough 18 and the float 204 for powder to enter. When it is in the sewage state, the float 204 falls to block the water inlet trough 18 and prevent a large amount of colloid from entering. Secondly, in the process of the float 204 falling, the scraper 22 and the tooth groove 23 connected to the bottom thereof can just clean the impurities located at the inner corner of the water inlet trough 18, thereby avoiding the problem of clogging of the water inlet trough 18.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
