Description

Technical Field

[0001] The present application relates to industrial wastewater filtration technology, and in particular to a side filter. Background Art

[0002] The side filter is mainly used for filtering industrial wastewater, using a specific filter layer to remove particulate matter in the wastewater, reduce the turbidity of the wastewater, and adsorb organic matter and ions in the wastewater.

[0003] At present, a side filter used for industrial wastewater filtration includes a tank body, wherein an activated carbon particle layer and a quartz sand layer are arranged inside the tank body from bottom to top, a feeding port for adding activated carbon particles and quartz sand is arranged on the top of the tank body, and the tank body is connected with an inlet pipe and a drain pipe. In order to improve the backwashing effect, and because the blocking materials are concentrated at the upper end of each filter material layer, backwashing structures are arranged in the activated carbon particle layer and the quartz sand layer, and all backwashing structures are connected with a backwashing pipe at the same time, and a sewage pipe connected to the tank body is arranged above the quartz sand layer, wherein valves are installed on the inlet pipe, the drain pipe, the sewage pipe and the backwashing pipe.

[0004] However, when adding activated carbon particles and quartz sand to the tank body for the first time or later when replacing the filter layer, they are added directly into the tank body from the feeding port, and the position of the feeding port is fixed. Therefore, after the activated carbon particles and quartz sand enter the tank body, they will accumulate into a cone. In order to ensure the uniform thickness of the filter layer, the staff needs to flatten each filter layer from the inspection port of the tank body with tools such as shovels. Not only is the operation complicated, but the entire adding work is time-consuming and inefficient. In addition, the wastewater to be treated usually falls directly onto the filter layer from the water inlet pipe, so the wastewater cannot fall evenly on the filter layer, which in turn causes the wastewater to not evenly pass through the filter layer, and part of the filter layer cannot be effectively utilized.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0037] like Figure 1-Figure 7 As shown:

[0038] A side filter provided in one embodiment of the present application comprises a tank body 1, on which a feed port 2, a water inlet pipe 3, a drain pipe 4 and a backwashing device are provided.

[0039] Furthermore, the feed port 2 and the water inlet pipe 3 are located at the bottom of the tank body 1 , and the drain pipe 4 is located at the bottom of the tank body 1 .

[0040] The interior of the tank body 1 is provided with an activated carbon particle layer 5 and a quartz sand layer 6. Specifically, a partition plate 7 for supporting the filter material layer is provided inside the tank body 1, the edge of the partition plate 7 is sealed and connected to the interior of the tank body 1, a plurality of filter caps (not shown in the figure) evenly distributed are installed on the partition plate 7, the activated carbon particle layer is located at the upper end of the partition plate 7, and the quartz sand layer 6 is located at the upper end of the activated carbon filter layer.

[0041] Both the water inlet pipe 3 and the drain pipe 4 are equipped with valves 25 .

[0042] The tank body 1 is provided with a feeding trough 8 which can swing back and forth, and the feeding trough 8 can be horizontally distributed and fixed. The bottom of the feeding trough 8 is a mesh plate structure. The feeding trough 8 is located below the feeding port 2 and the water inlet pipe 3 at the same time.

[0043] Furthermore, the material distributing trough 8 is a hollow structure with an open upper end.

[0044] In this embodiment, a bracket 26 is provided at the bottom of the tank body 1 for supporting the tank body 1 .

[0045] When adding filter material into the tank body 1, first let the distribution groove 8 swing back and forth, and then add activated carbon particles into the tank body 1 from the feeding port 2. The activated carbon particles first fall into the distribution groove 8 and flow back and forth in the distribution groove 8 according to the swinging direction of the distribution groove 8. At the same time, the activated carbon particles are evenly spread on the partition 7 from the bottom of the distribution groove 8. The activated carbon particles form an activated carbon particle layer 5 on the partition 7. When the activated carbon particle layer 5 reaches a certain thickness, the work of adding activated carbon particles is stopped. Then, quartz sand is added from the feeding port 2. The quartz sand falls on the reciprocating distribution groove 8 and is evenly spread on the activated carbon particle layer 5 from the distribution groove 8 to form a quartz sand layer 6. When the quartz sand layer 6 reaches a certain thickness, the feeding work is stopped. Finally, the distribution groove 8 is adjusted to be horizontally distributed, and then the filtering work can be carried out.

[0046] During filtration, the waste water falls from the water inlet pipe 3 onto the horizontally distributed distribution trough 8, and falls evenly from the bottom of the distribution trough 8 to the upper end of the quartz sand layer 6, and then passes through the quartz sand layer 6 and the activated carbon particle filter layer in turn, the quartz sand layer 6 and the activated carbon particle filter layer filter the waste water, and finally passes through the bottom of the filter cap flow tank 1 and is discharged from the drain pipe 4.

[0047] The side filter provided in this embodiment has a feed port 2, a water inlet pipe 3, a drain pipe 4 and a backwashing device on the tank body 1, an activated carbon particle layer 5 and a quartz sand layer 6 are provided inside the tank body 1, the water inlet pipe 3 and the drain pipe 4 are both equipped with valves 25, and a distribution trough 8 that can swing back and forth is provided inside the tank body 1, and the distribution trough 8 can be horizontally distributed and fixed, the bottom of the distribution trough 8 is a mesh structure, and the distribution trough 8 is located below the feed port 2 and the water inlet pipe 3 at the same time, so that when adding filter material, the distribution trough 8 can evenly spread the filter material in the tank body 1 after reciprocating swing, thereby avoiding the problem of the filter material being accumulated into a cone after addition, eliminating the step of manually flattening the filter material, and improving the efficiency of adding the filter material. In addition, after the distribution trough 8 is adjusted to be horizontally distributed, the wastewater can pass through the bottom of the distribution trough 8 and be evenly distributed on the filter material layer, so that the filter material layer as a whole can be effectively utilized.

[0048] In some embodiments of the present application, the material distributing trough 8 is rotatably connected to the tank body 1 through two symmetrically distributed rotating shafts 9. Specifically, one end of the rotating shaft 9 is fixedly connected to the outer wall of the material distributing trough 8, and the other end of the rotating shaft 9 is rotatably connected to the tank wall of the tank body 1 through a bearing. A torsion spring 10 is sleeved on each rotating shaft 9, and the torsion spring 10 is connected to the material distributing trough 8 and the tank body 1 at the same time. When the torsion spring 10 is in a free state, the material distributing trough 8 is tilted. A reciprocating linear motion mechanism 11 is installed on the tank body 1, which can drive one end of the material distributing trough 8 to rotate downward intermittently.

[0049] In this embodiment, when the torsion spring 10 is in a free state, the right end of the material distribution groove 8 is distributed obliquely upward, and the reciprocating linear motion mechanism 11 can drive the right end of the material distribution groove 8 to rotate downward intermittently.

[0050] When in use, after the reciprocating linear motion mechanism 11 moves downward, the reciprocating linear motion mechanism 11 pushes the material distribution groove 8 to rotate downward around the center of the rotating shaft 9. At the same time, the torsion spring 10 is deformed. After the material distribution groove 8 rotates downward by a certain angle, the reciprocating linear motion mechanism 11 moves upward, the torsion spring 10 recovers, and drives the material distribution groove 8 to rotate upward. When the reciprocating motion mechanism moves upward for a certain distance, it moves downward again and pushes the material distribution groove 8 to move downward. After the reciprocating motion mechanism moves back and forth, under the action of the torsion spring 10, the reciprocating swing of the material distribution groove 8 is realized.

[0051] In some embodiments of the present application, the reciprocating linear motion mechanism 11 includes an electric push rod 12 capable of reciprocating and telescoping, and a push piece 13 is fixed to the automatic end of the electric push rod 12 .

[0052] A rectangular plate 14 capable of contacting the push piece 13 is fixed to the upper end of the material distributing groove 8 .

[0053] Furthermore, in order to improve the stability of the rectangular plate 14, one end of the rectangular plate 14 is fixedly connected to the upper end of the material distribution trough 8, and a support rod 15 is fixed to the other end of the rectangular plate 14, and both ends of the support rod 15 are fixedly connected to the inner wall of the material distribution trough 8 at the same time.

[0054] In this embodiment, the electric push rod 12 is vertically fixed to the upper end of the tank body 1, and the free end of the electric push rod 12 extends into the interior of the tank body 1. The electric push rod 12 capable of reciprocating telescopic movement is a prior art and will not be described in detail.

[0055] When in use, the electric push rod 12 extends, driving the push piece 13 to move downward, and the push piece 13 pushes the rectangular plate 14 to rotate downward around the center of the rotating shaft 9, and the rectangular plate 14 drives the material distributing trough 8 to rotate downward synchronously with it, and the torsion spring 10 is deformed. The electric push rod 12 retracts, the push piece 13 moves upward, the torsion spring 10 recovers, and the material distributing trough 8 and the rectangular plate 14 rotate upward synchronously. Therefore, after the electric push rod 12 reciprocates and retracts, the reciprocating swing of the material distributing trough 8 can be realized.

[0056] In some embodiments of the present application, the push member 13 is a cylindrical structure, and the push member 13 is rotatably connected to the free end of the electric push rod 12 .

[0057] In this embodiment, by providing a rotatable pushing member 13 , the pushing member 13 can smoothly push the rectangular plate 14 to rotate.

[0058] In some embodiments of the present application, one of the rotating shafts 9 extends out of the tank body 1 and is fixed with a hand wheel 16, a locking bolt 17 is threadedly connected to the hand wheel 16, and a socket 18 adapted to the locking bolt 17 is opened on the tank body 1. Specifically, the outer diameter of the threaded portion of the locking bolt 17 is equal to the inner diameter of the socket 18.

[0059] After the material distributing groove 8 is horizontally distributed, the locking bolt 17 can be inserted into the insertion hole 18 .

[0060] During use, after the filter material is added, the electric push rod 12 is adjusted so that the right end of the distribution trough 8 is distributed obliquely upward, and then the staff holds the hand wheel 16 and turns the hand wheel 16 to move the locking bolt 17 to the side of the socket 18, and finally screws the locking bolt 17 into the socket 18, thereby achieving the effect of fixing the distribution trough 8 after the distribution of the material is horizontal.

[0061] In some embodiments of the present application, the backwashing device includes a backwashing structure 20 and a sewage pipe 23 connected to the tank body 1 , and the sewage pipe 23 is located above the quartz sand layer 6 .

[0062] There are two backwash structures 20, one of which is located in the activated carbon particle layer 5, and the other is located in the quartz sand layer 6. The two backwash structures 20 are connected to the backwash pipe 19 at the same time.

[0063] Valves 25 are installed on the backwash pipe 19 and the sewage pipe 23.

[0064] When backwashing is required, the valves 25 on the water inlet pipe 3 and the drain pipe 4 are closed, and the valves 25 on the backwash pipe 19 and the sewage pipe 23 are opened. Clean water enters the two backwash structures 20 from the backwash pipe 19, and directly enters the activated carbon filter layer and the quartz sand layer 6 from the backwash structure 20, so that the pressurized clean water can directly contact the substances that clog the filter layer for the first time, thereby improving the backwashing effect. Finally, the clean water carries the substances that clog the filter layer out of the sewage pipe 23.

[0065] In some embodiments of the present application, the backwashing structure 20 includes a water distribution pipeline 21, and a plurality of concentric annular water distribution components located in the same plane are installed at the upper end of the water distribution pipeline 21. The annular water distribution component is composed of a plurality of annular nozzles 22, so that the nozzles 22 can be evenly distributed in the filter material layer, thereby allowing the pressurized clean water to flow evenly in the filter material layer, thereby further improving the backwashing effect.

[0066] The water distribution pipeline 21 is connected to the backwash pipe 19 .

[0067] In some embodiments of the present application, a controller (not shown) and a hydraulic pressure gauge 24 are also included, and the hydraulic pressure gauge 24 is installed on the sewage pipe 23, and the hydraulic pressure gauge 24 is located between the tank body 1 and the valve 25 installed on the sewage pipe 23. All valves 25 are electric valves 25, and all valves 25 and hydraulic pressure gauges 24 are connected to the controller at the same time.

[0068] When in use, the hydraulic gauge 24 monitors the water pressure value above the quartz sand layer 6 and sends the measured water pressure value to the controller. The controller compares the water pressure value with a preset threshold value. If the measured water pressure value is greater than the threshold value, it means that the filter layer is seriously clogged. At this time, the controller issues a control command to close the valves 25 on the water inlet pipe 3 and the drain pipe 4, open the valves 25 on the backwash pipe 19 and the sewage pipe 23, and switch the bypass filter from the filtering state to the backwashing state. Then, clean water enters the filter layer from the backwashing structure 20 to perform backwashing. After the backwashing is completed, the controller controls the closing of the valves 25 on the backwashing pipe 19 and the sewage pipe 23, opens the valves 25 on the water inlet pipe 3 and the sewage pipe 4, and continues the filtering work.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features therein may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
