Description

Technical Field

[0001] The invention relates to a sedimentation and filtering device of an ecological tail water treatment system. Background Art

[0002] Aquaculture is an important part of agricultural production and plays an important role in the national economy. It has developed rapidly in the past fifty years. However, with the continuous expansion of aquaculture scale, the problems of frequent diseases and poor product quality have become increasingly prominent. The occupation and consumption of a large amount of resources have caused ecological balance and environmental deterioration. In addition, the limitations of technology and resources have greatly restricted its development. Under this background, the development of aquaculture towards factoryization is imperative.

[0003] In the process of aquaculture, not only will there be a large accumulation of organic substances such as leftover bait and excrement, but also a large amount of toxic and harmful inorganic substances in the water body. In view of the above reasons, we need to regularly discharge tail water containing toxic and harmful substances in the process of aquaculture to ensure the healthy growth of the aquaculture objects. To raise shrimps, you must first raise water. Whether there is a harvest or not depends on the water. It can be seen that the quality of aquaculture water has a great impact on the success of aquaculture. There are leftover bait, shrimp excrement, animal and plant carcasses, organic matter deposited at the bottom of the pond, and microorganisms such as bacteria and viruses in the aquaculture water body. The content of nitrogen and phosphorus in the tail water is high. In order to promote the growth of shrimp, tail water will be discharged regularly. At present, the treatment system for tail water discharge is mainly a static sedimentation tank, and then through physical filtration such as ceramsite, volcanic stone or pebbles. Such purification effect can only filter out large solids such as excrement, and it is difficult to remove organic matter such as nitrogen and phosphorus, and the tail water treatment effect is not good. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] Refer to Figure 1-Figure 5 As shown, the first embodiment of the present application provides a sedimentation and filtration device of an ecological tailwater treatment system, including at least one brush treatment pool 1, in which multiple rows of equidistant brush members 2 are installed, and multiple rows of brush members 2 all include a connecting frame 3, the connecting frame 3 is higher than the water surface of the brush treatment pool 1, and multiple filter brushes 4 are evenly distributed on the connecting frame 3, and the filter brushes 4 are used to intercept organic matter in the pool. Multiple expansion pools 5 or a total expansion pool 5 are opened on the side of the brush treatment pool 1, and the expansion pool 5 and the brush treatment pool 1 are connected to each other through a first opening 6, and the first opening 6 is for the filter brush 4 to enter the expansion pool 5.

[0031] Since the brush in the prior art is hung on a hanging rod, and then the hanging rod is placed on a steel frame, when the brush needs to be cleaned, the brush is taken out from the hanging rod and cleaned, and then the brush is reinstalled on the hanging rod after cleaning. First of all, there are a large number of brushes in the entire brush treatment pool 1, and some brush treatment pools 1 are deeper, resulting in a longer overall length of the brushes, which requires greater strength for manual removal or cleaning, so the present application improves it; specifically, the connecting frame 3 includes a straight section 7 and a planar spiral section 8, the connection between the planar spiral section 8 and the straight section 7 is a detachable connection, and the detachable connection is preferably a snap connection, the straight section 7 is provided with a protrusion on the end face facing the planar spiral section 8, and the straight section 7 is provided with a bayonet corresponding to the protrusion, and the straight section 7 and the planar spiral section 8 are both provided with a track 9 for the sliding of the filter brush 4, and the track 9 is slidably connected with a traction push block 10, and the traction push block 10 includes two mutually attractive first magnet blocks 101 and second magnet blocks 102, the first magnet block 101 is fixedly connected to the first traction rope 11, the first traction rope 11 is provided with a first winding end 111, the second magnet block 102 is fixedly connected to the second traction rope 12, and the first magnet block 101 and the second magnet block 102 are both slidably connected to the side wall of the track 9. The reason for configuring the traction push block 10 to be the first magnet block 101 and the second magnet block 102 is to accommodate the detachability of the straight section 7 and the planar spiral section 8, thereby ensuring the switching back and forth between the collection and reset of the filter brush 4. The first winding end 111 and the second winding end 121 are preferably motor-driven winding of the traction rope. When the first winding end 111 starts the winding of the first traction rope 11 in the forward direction, the second winding end 121 reverses and starts the coiling of the second traction rope 12, thereby enabling the first magnet block 101 to move the filter brush 4 to the planar spiral section 8, transforming the horizontal setting of the filter brush 4 into a winding setting, and the first magnet block 101 limits the unfolding of the filter brush 4 by restricting the winding length of the first traction rope 11, and winding the filter brush 4 in At the same time, the filter brush 4 is taken out of the expansion pool 5 for cleaning: all the filter brushes 4 can be taken out by pulling the flat spiral section 8 and the filter brushes 4 are rolled up and gathered together for easy cleaning, and the filter brush 4 is rinsed from multiple angles by a high-pressure water gun. After rinsing, the flat spiral section 8 with the filter brush 4 is placed back into the expansion pool 5, and the first magnet block 101 and the second magnet block 102 are re-attracted, the second winding end 121 is started to rotate forward, and the first winding end is reversed, so that the filter brush 4 returns to the straight section 7.

[0032] like Figure 3 , Figure 4As shown, in order to keep the adjacent spacing of the filter brush 4 consistent after it returns to the straight section 7, and to be able to be rolled up onto the flat spiral section 8 when the filter brush 4 needs to be cleaned, a spacing adjustment member 13 is provided between adjacent filter brushes 4. The spacing adjustment member 13 includes a V-shaped hinged rod 131 provided between adjacent filter brushes 4, and the ends of the V-shaped hinged rod 131 are rotatably connected to the adjacent filter brushes 4. A reset telescopic portion 132 is provided between the V-shaped hinged rods 131. The reset telescopic portion 132 is used to adapt to the compression and rearrangement of the adjacent spacing of the filter brush 4 during the cleaning process so that it can be restored to the original adjacent spacing, thereby reducing manual adjustment of the spacing of the filter brush 4. The reset telescopic portion 132 includes an arc-shaped telescopic block provided between the V-shaped hinged rods 131, and a telescopic spring is provided between the arc-shaped telescopic blocks. The reset telescopic portion 132 belongs to the prior art and will not be elaborated here.

[0033] Refer to Figure 6-Figure 9 As shown, the present application provides a second embodiment, which is basically the same as the first embodiment, with the only difference that the connecting frame 3 includes a straight section 7 and a planar spiral section 8, the straight section 7 and the planar spiral section 8 are integrally formed, and the straight section 7 and the planar spiral section 8 are both installed in the brush treatment pool 1 and the expansion pool 5 through limiting members.

[0034] The first opening 6 is provided with a retractable water baffle 14 , and the retractable water baffle 14 is used to block the communication between the expansion pool 5 and the brush treatment pool 1 .

[0035] A drainage pipe 18 is provided between the multiple expansion pools 5 and the brush treatment pool 1, and the drainage pipe 18 is used to discharge the tail water in the expansion pool 5 back to the brush treatment pool 1. A drainage spray component 17 is commonly provided between the multiple expansion pools 5, and the drainage spray component 17 is used to flush the filter brush 4.

[0036] A brush cleaning member 15 is provided in the expansion pool 5, and the brush cleaning member 15 includes a shell cavity 151 with a planar spiral formed by splicing multiple filter plates. An inclined plate 152 facing the filter brush 4 is provided at the upper end of the shell cavity 151, and cleaning bristles or cleaning rollers are laterally provided at the end of the inclined plate 152. A lifting member 16 is arranged between the shell cavity 151 and the expansion pool 5, and the lifting member 16 is used to lift the shell cavity 151.

[0037] The above-mentioned specific improvement, in order to reduce the process of the filter brush 4 moving back and forth, is set in the expansion pool 5 to clean its filter brush 4, so the straight section 7 and the flat spiral section 8 in the connecting frame 3 can be set to be integrally formed, and installed on the brush treatment pool 1 and the expansion pool 5 through the limiter, and the limiter includes a steel frame or other objects that can support the connecting frame 3. Of course, the connecting frame 3 with a detachable connection method in Example 1 can also be continued to be used, according to actual conditions. A telescopic water baffle 14 is provided at the first opening 6, which can be used to separate the brush treatment pool 1 from the barrier expansion pool 5 after the filter brush 4 is reeled into the expansion pool 5 through the first traction rope 11, thereby reducing the circulation of water between the two pool bodies, so that when the filter brush 4 is cleaned in the expansion pool 5, it can reduce the intercepted objects on the bristles returning to the brush treatment pool 1. Depending on whether all filter brushes 4 are cleaned synchronously or in batches, it is determined whether the telescopic water baffle 14 is individually configured with a drive or the telescopic water baffles 14 on the same side use a common drive to close the first opening 6 on the same side to clean the filter brush 4. Further, a drainage pipe 18 is provided between multiple expansion pools 5 or the total expansion pool 5 and the brush treatment pool 1, and the drainage pipe 18 is used to discharge the tail water in the expansion pool 5 back to the brush treatment pool 1. A brush cleaning member 15 is provided in the expansion pool 5, and the brush cleaning member 15 includes a shell cavity 151 with a plane spiral formed by splicing multiple filter plates, an oblique plate 152 facing the filter brush 4 is provided at the upper end of the shell cavity 151, and a cleaning brush or a cleaning roller is transversely provided at the end of the oblique plate 152, and the cleaning brush and the cleaning roller are both made of flexible materials. A lifting member 16 is provided between the shell cavity 151 and the expansion pool 5, and the lifting member 16 can be driven by a screw rod or other means to achieve vertical linear motion of the shell cavity 151. When the brush cleaning part 15 is cleaned, multiple expansion pools 5 or the total expansion pool 5 are provided with a drainage spraying part 17. The drainage spraying part 17 includes draining the water in the tailwater system that can be used to clean the brush through the drainage pipe. After the drainage, the high-pressure spraying head set on the expansion pool 5 rinses the filter brush 4. While the inclined plate 152, the cleaning brush or the cleaning roller are cleaning upward, the high-pressure spraying head rinses the filter brush 4 downward to achieve the maximum extent. The intercepted objects on the filter brush 4 are collected in the shell cavity 151, and the intercepted objects in the shell cavity 151 are subsequently cleaned. In this way, there is no need to clean it manually, just start the corresponding components through the controller to clean it, and after cleaning, start the winding end to move the traction push block 10 to move the filter brush 4 back to the brush treatment pool 1.
