Technical problem

The utility model aims to provide a water purifying device which can separate suspended matters from raw water and filter clear water.

Technical proposal

According to an embodiment of the present utility model, there is provided a water purifying apparatus including: a clarifier for separating suspended matters in raw water to obtain clear water, and storing the clear water in a clear water zone at the upper part of the clarifier; one end of the capillary filtering part extends into the clean water in the clean water zone from the upper part of the clean water zone, and filters and sucks the clean water through capillary action; and a clear water collecting pipe which is communicated with the other ends of the capillary filtering parts and receives clear water filtered and sucked out by the capillary filtering parts and discharges the clear water outwards. Therefore, suspended matter separation and clear water filtration can be carried out on raw water by using only one device, so that the number of equipment is reduced, and the occupied area and the cost are saved.

In some embodiments, the capillary filtration portion comprises a plurality of capillary primary tube bundles and a plurality of capillary branch tube bundles extending from the capillary primary tube bundles, wherein the capillary primary tube bundles and the capillary branch tube bundles are respectively provided with a plurality of primary capillaries and branch capillaries and are wrapped by a tube sleeve, wherein the capillary primary tube bundles comprise a first part which is distributed above the clear water zone along the horizontal direction and a second part which is communicated with the first part and extends vertically downwards along the outer side of the clarification tank, and the capillary branch tube bundles extend downwards from the first part of the capillary primary tube bundles and extend into clear water in the clear water zone. Therefore, clear water can be filtered at a plurality of positions at the same time, so that the filtering efficiency is improved.

In some embodiments, the first portion of the primary capillary tube bundle extends radially of the clarifier and the primary capillary tube bundles on each of the first portion of the primary capillary tube bundles are disposed apart by a prescribed distance. Therefore, the plurality of capillary branch tube bundles can be distributed more uniformly, and the overall filtering efficiency of the clear water is improved.

In some embodiments, the branch capillary is formed by connecting a plurality of capillary short pipes with different inner diameters, and the inner diameters of the capillary short pipes which are farther from the capillary main pipe bundle are larger. Therefore, clear water can be filtered in a layered manner, and the branch capillary tube is prevented from being blocked more effectively.

In some embodiments, the capillary tube has an inner diameter of 0.05 to 0.2mm. Thus, the capillary action is ensured, and the high filtration amount is maintained.

In some embodiments, the diameter ratio of the primary capillary to the secondary capillary is 2:1 at the junction of the primary capillary and the secondary capillary. Thus, the clean water passing through the branch capillary can smoothly enter the main capillary and flow out.

In some embodiments, the location at which the capillary primary tube bundle communicates with the clean water collection tube is below the lowest level of clean water in the clean water zone. Thereby, it is ensured that the clean water in the clean water zone is smoothly discharged to the outside through the capillary filter portion.

In some embodiments, further comprising: and a back flush part connected to the clean water collecting pipe for back flushing the capillary filtration part, the back flush part comprising: the air pressure unit is used for generating high-pressure air; a gas storage unit for storing the high-pressure gas generated by the air pressure unit; the air outlet channel is communicated with the clear water collecting pipe, so that high-pressure air in the air storage unit is communicated with the clear water collecting pipe and is blown into the capillary filtration part to backwash the capillary filtration part; and the air outlet valve is arranged in the air outlet channel and used for opening and closing the air outlet channel. Thereby, not only the capillary filtration portion can be dredged, but also the clean water in the clean water zone can be agitated and turbulent flow can be formed to wash the bottom of the clean water zone.

In some embodiments, further comprising: the water outlet valve is arranged on the clear water collecting pipe and is far away from the clarification tank relative to the backwashing part and is used for switching on and off the clear water collecting pipe; and the water level monitoring part is arranged in the clear water area and is in communication connection with the back flushing part, when the liquid level of clear water in the clear water area is higher than a preset height, the water outlet valve is closed, the back flushing part is used for back flushing the capillary filtering part, and when the back flushing is finished, the water outlet valve is opened. Thus, the back flushing can be performed at an appropriate time, and the high-pressure gas can be accurately flowed to the capillary filter portion side.

In some embodiments, further comprising: and the inclined tube sedimentation zone is positioned at the bottom of the clear water zone and is used for further carrying out inclined tube sedimentation on clear water which is about to enter the clear water zone. This can further improve the water purifying effect.

One or more embodiments of the present utility model will be described in detail below with reference to the drawings so that those skilled in the art can clearly and completely understand the present utility model.

According to an embodiment of the present utility model, there is provided a water purifying apparatus 1, which may include a clarifier 2, a capillary filtration section 3, and a clear water collection pipe 4. The type of the clarifier 2 may be a mechanical acceleration clarifier 2, a hydraulic circulation clarifier 2, a suspension clarifier 2, or a pulse clarifier 2, and one skilled in the art may select an appropriate clarifier 2 according to specific conditions, and the present utility model is not limited thereto. For convenience of explanation, hereinafter, a mechanically accelerated clarification tank 2 is selected as the clarification tank 2 for use as an example in the drawings, and the water purifying apparatus 1 of the present utility model will be described in detail.

Fig. 1 is a cross-sectional view of a water purifying apparatus according to an embodiment of the present utility model. Fig. 2 is a plan view of a water purifying apparatus according to an embodiment of the present utility model. Fig. 3 is a plan view of a water purifying apparatus according to another embodiment of the present utility model. Fig. 4 is a schematic view of a branch capillary according to an embodiment of the present utility model.

As an embodiment, the clarifier 2 is capable of separating suspended substances in raw water to obtain clean water and storing the clean water in the clean water zone 21 located at an upper portion thereof; one end of the capillary filter part 3 extends into the clean water in the clean water zone 21 from above the clean water zone 21, and filters and sucks the clean water through capillary action; and a clear water collecting pipe 4 which is communicated with the other ends of the plurality of capillary filtration parts 3, receives clear water filtered and sucked out by the capillary filtration parts 3 and discharges the clear water outwards. Therefore, the utility model can separate suspended matters from raw water and filter clear water by only using one device, thereby reducing the number of equipment and saving the occupied area and the cost.

Wherein, the capillary filtering portion 3 may include a plurality of capillary main tube bundles 31 and a plurality of capillary branch tube bundles 32 extending from the capillary main tube bundles 31, and a plurality of main capillaries and branch capillaries 321 may be respectively disposed in the capillary main tube bundles 31 and the capillary branch tube bundles 32 and wrapped by a tube sleeve (not shown). Wherein the capillary primary tube bundle 31 comprises a first portion 311 which is horizontally distributed over the clean water zone 21 and a second portion 312 which communicates with the first portion 311 and extends vertically downwards along the outside of the clarifier 2, and the capillary branch tube bundles 32 extend downwards from the first portion 311 of the capillary primary tube bundle 31 and into the clean water in the clean water zone 21. Therefore, the plurality of capillary branch tube bundles 32 arranged on the plurality of branch capillaries 321 simultaneously extend into the clean water, so that the clean water can be filtered at a plurality of positions simultaneously, and the filtering efficiency is improved.

As an embodiment, as shown in fig. 2, the first portion 311 of the capillary primary tube bundle 31 may extend in the radial direction of the clarifier 2, and the capillary branch tube bundles 32 on the first portion 311 of each capillary primary tube bundle 31 may be arranged at a prescribed distance apart. This makes it possible to more uniformly distribute the plurality of capillary branch bundles 32, thereby improving the overall filtration efficiency of the fresh water. As another embodiment, as shown in fig. 3, the capillary branch bundles 32 may further extend in pairs at a position on the capillary main bundles 31, and a pair of the capillary main bundles 31 may be directly connected to each other or may be connected by additional capillary bundles having different inner diameters.

Further, as shown in fig. 4, the branch capillary 321 may be formed by connecting a plurality of capillary short tubes having different inner diameters, and the further the distance from the capillary main tube bundle 31, the larger the inner diameter of the capillary short tube. Therefore, clear water can be filtered in a layered manner, and blockage of the branch capillary 321 can be avoided more effectively. That is, at the opening of the branch capillary 321, the inside diameter is the largest, and impurities with larger diameter can be blocked without affecting the inflow of clean water into the branch capillary 321, and when impurities with relatively smaller diameter flow into the branch capillary 321 along with clean water, the capillary pipe with the next inside diameter energy efficiency can be blocked less. In addition, the inflow of the clean water into the branch capillary 321 gradually decreases as the diameter is continuously blocked outside the respective capillary tubes, and at this time, the structure of the branch capillary 321 is more advantageous in improving the suction effect for the clean water introduced into the branch capillary 321.

The inner diameter of the capillary tube may be 0.05-0.2 mm. Thus, the capillary action is ensured, and the high filtration amount is maintained. In view of this, as an embodiment, the branch capillary 321 may be formed by connecting 6 capillary tubes having inner diameters of 0.05mm, 0.15mm, 0.25mm, 0.5mm, 1.0mm, and 2.0mm in order. Of course, the length, the inner diameter and the number of the capillary tubes can be adjusted by those skilled in the art according to the actual situation, and the present utility model is not limited thereto.

After being sucked from the clear water zone 21 to the top of the capillary branch tube bundles 32 by the plurality of capillary branch tube bundles 32, the clear water merges into the first portion 311 of the capillary main tube bundle 31 extending in the horizontal direction, and thus, the inner diameter of the main capillary should be larger than the inner diameter of the branch capillaries 321 to satisfy the flow rate of the clear water. Thus, as one embodiment, where the primary capillary and the secondary capillary 321 are joined, the diameter ratio of the primary capillary to the secondary capillary 321 may be 2:1. Thus, the clean water passing through the branch capillary 321 can smoothly enter the main capillary and flow out. When the diameter ratio of the main capillary to the branch capillary 321 is larger than 2:1, the capillary action of the main capillary to the clean water is reduced, and when the diameter ratio of the main capillary to the branch capillary 321 is smaller than 2:1, the flow rate of the clean water in the main capillary is reduced. Of course, the person skilled in the art can adjust the above-mentioned ratio according to the actual situation.

Thereafter, the fresh water entering the first portion 311 of the capillary main tube bundle 31 flows in the horizontal direction and reaches the second portion 312 of the capillary main tube bundle 31 extending in the vertical direction, and then flows down to the fresh water collecting tube 4 through the second portion 312 of the capillary main tube bundle 31 and is discharged outward. Considering that a water pressure difference needs to be formed between the fresh water zone 21 and the fresh water collecting pipe 4 to facilitate the suction and discharge of fresh water, as an embodiment, the position where the capillary main tube bundle 31 communicates with the fresh water collecting pipe 4 may be below the lowest level of fresh water in the fresh water zone 21. Thereby, it is ensured that the clean water in the clean water zone 21 is smoothly discharged to the outside through the capillary filtration portion 3. On the basis of this, the position at which the capillary main tube bundle 31 communicates with the fresh water collecting tube 4 can be adjusted according to the required filtration amount to adjust the height difference between this position and the liquid level of fresh water in the fresh water zone 21. When the required filtration amount is large, the position where the capillary main tube bundle 31 communicates with the clear water collection tube 4 may be set lower to increase the height difference; when the required filtration amount is small, the position where the capillary main tube bundle 31 communicates with the fresh water collecting tube 4 may be set higher to reduce the height difference.

In some embodiments, the water purifying apparatus 1 of the present utility model may further include: and the back flushing part 5 is connected with the clean water collecting pipe 4 and is used for back flushing the capillary filtering part 3. Specifically, the backwash part 5 may include: a pneumatic unit 51 for generating a high-pressure gas; a gas storage unit 52 for storing the high-pressure gas generated by the air pressure unit 51; the air outlet channel 53 is communicated with the clean water collecting pipe 4, so that high-pressure air in the air storage unit 52 is communicated with the clean water collecting pipe 4 and is blown into the capillary filtration part 3 to back wash the capillary filtration part 3; and an air outlet valve 54 provided in the air outlet passage 53 for opening and closing the air outlet passage 53. The materials, types, etc. of the air compression unit 51, the air storage unit 52, the air outlet channel 53, and the air outlet valve 54 can be selected by those skilled in the art according to practical situations. For example, the air compressor unit 51 may be a variety of air compressors such as a positive displacement compressor, a piston compressor, and a rotary compressor; the air storage unit 52 may be a compressed air tank or the like. Thereby, not only the capillary filtration portion 3 but also the clean water in the clean water zone 21 can be agitated and turbulent flow is formed to wash the bottom of the clean water zone 21.

On the other hand, as an embodiment, the water purifying apparatus 1 of the present utility model may further include: the water outlet valve 6 is arranged on the clear water collecting pipe 4 and is far away from the clarification tank 2 relative to the back flushing part 5, and is used for switching on and off the clear water collecting pipe 4; and a water level monitoring part which is arranged in the clear water area 21 and is in communication connection with the back flushing part 5, when the liquid level of clear water in the clear water area 21 is higher than a preset height, the water outlet valve 6 is closed, the back flushing part 5 is used for back flushing the capillary filtration part 3, and when back flushing is completed, the water outlet valve 6 is opened. This makes it possible to perform back flushing at an appropriate timing and to accurately flow the high-pressure gas to the capillary filter portion 3 side.

In some embodiments, the water purifying apparatus 1 of the present utility model may further include: and the inclined tube sedimentation zone 22 is positioned at the bottom of the clean water zone 21 and is used for further carrying out inclined tube sedimentation on the clean water which is going to enter the clean water zone 21. This can further improve the water purifying effect.

While the embodiments of the present utility model have been described above, the present utility model is not limited to the above description, and those skilled in the art can make various modifications and variations from these descriptions, only to assist in a comprehensive understanding of the present utility model. The technical idea of the present utility model is therefore not limited to the above-described embodiments, and the appended claims and their equivalents or equivalent modifications all fall within the scope of the present utility model.
