DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] Please see Figures 1 to 6 The utility model provides a solid-liquid separation device for aquaculture wastewater. In the prior art, direct discharge of aquaculture wastewater residues will seriously affect the surrounding environment, deteriorate its water quality, and seriously damage the growth of aquatic plants. In order to solve the above technical problems, the utility model sets a separation device to perform solid-liquid separation on the aquaculture wastewater residues and purify the wastewater at the same time, thereby achieving the purpose of reducing the impact of aquaculture wastewater residues on the environment.

[0027] The structure of the solid-liquid separation device of the present invention is shown in the figure, which mainly includes a box body 100, and a feeding port 101 is arranged on the top of the box body 100. There are multiple feeding ports 101, and they are arranged at intervals so that wastewater can be put in in a dispersed manner. A solid-liquid separation mechanism 200 is arranged near the top of the box body 100, and the solid-liquid separation mechanism 200 includes two symmetrically installed sieve plates 210, and the sieve plates 210 are also arranged tilted downward. There are several sieve holes on the sieve plate 210 (the sieve holes are not shown in the figure), and a cam column 220 is arranged at the bottom of the sieve plate 210. The cam column 220 is semicircular. After installation, the cam column 220 is arranged in the middle, and a lifting component 230 is arranged at the bottom of the cam column 220. In addition, the top of the sieve plate 210 is rotatably connected to the inner wall of the box body 100. Under the action of the lifting component 230, the cam column 220 and the sieve plate 210 are driven to rise and fall by a certain amplitude.

[0028] The rotational connection between the sieve plate 210 and the box body 100 is achieved by providing a support plate 102 on the inner wall of the box body 100. As shown in the figure, two support plates 102 are provided on the same side, a rotating shaft 103 is provided between the two support plates 102, and a rotating drum 211 is provided on the top plate of the sieve plate 210. The rotating drum 211 is sleeved on the rotating shaft 103, and the sieve plate 210 and the cam column 220 are driven to move up and down under the action of the lifting component 230 at the bottom. During the movement, the waste liquid residue poured onto the sieve plate 210 is screened, so that large impurities will remain on the sieve plate 210. During the up and down movement, it can also reduce the sieve holes of the sieve plate 210 from being blocked, thereby affecting the solid-liquid separation effect.

[0029] The utility model particularly arranges a cam column 220 between the two sieve plates 210, and the cam faces upward. During the solid-liquid separation process, since the sieve plates 210 are installed tilted downward, after the wastewater is poured in, it will flow to the bottom of the two sieve plates 210. The wastewater contains a large amount of debris, impurities, etc., which are very easy to accumulate over a long period of time, and the accumulation will become larger and larger, thereby reducing the effective area of ​​solid-liquid separation. In order to reduce the impact, the cam column 220 is arranged. Since it is arranged as the cam column 220, its bottom is round and smooth. Under the action of the lifting component 230, the cam column 220 is upward, which will drive the wastewater on the sieve plate 210 to flow, and under the action of the sieve holes, the solid and liquid will be gradually screened.

[0030] For greater flexibility, a rotational connection may be provided between the sieve plate 210 and the cam column 220. Similarly, mounting plates may be provided at both ends of the cam column 220, and a rotating rod may be provided on the mounting plates, and a sleeve may be provided at the bottom of the sieve plate 210. If the sieve plate 210 and the cam column 220 are not rotationally connected, impurities and the like will gradually accumulate between the angles of the cam column 220 and the sieve plate 210 when the sieve plate 210 is stopped, which facilitates cleaning.

[0031] The structure of the lifting assembly 230 is described again. The lifting assembly 230 includes a mounting shell 231, in which a driving cylinder 232 is arranged. The telescopic end of the driving cylinder 232 is connected to an adapter plate 233. The adapter plate 233 is provided with a support column 234 that can extend out of the mounting shell 231. A vertical plate 235 is arranged in the mounting shell 231. The vertical plate 235 is arranged around the driving cylinder 232 and a gap is left between the vertical plate 235 and the mounting shell 231. Under the action of the driving cylinder 232, the adapter plate 233 can be driven to move up and down, thereby driving the support column 234 to move up and down, and then driving the cam column 220 and the screen plate 210 to move up and down to a certain extent around the rotating shaft 103. Since the support column 234 needs to move up and down in the mounting shell 231, the vertical plate 235 can move up and down. There is a small gap between the support column 234 and the mounting shell 231, so the connection between the cam column 220 and the screen plate 210 is a direct connection, which can prevent most of the waste water from falling into the mounting shell 231. During the wastewater separation process, a small amount of waste water will always fall into the mounting shell 231. In order to avoid affecting the use of the driving cylinder 232, the adapter plate 233 is provided. The adapter plate 233 is close to the inner wall of the mounting shell 231, and a vertical plate 235 is provided at the bottom of the mounting shell 231 to enclose the driving cylinder 232. Even if a small amount of waste water falls into the mounting shell 231 through the gap, under the action of the adapter plate 233, it will only flow downward along the inner wall of the mounting shell 231 and be placed between the vertical plate 235 and the mounting shell 231, which will not affect the normal use of the driving cylinder 232.

[0032] In order to facilitate cleaning, a spray assembly 300 is also set on the top of the box body 100. The spray assembly 300 includes a water tank 310 arranged outside the box body 100 and a spray pipe 320 arranged at the top plate inside the box body 100, and a spray head is arranged below the spray pipe 320. When the equipment is not performing solid-liquid separation, even if the equipment is cleaned, water is filled into the water tank 310 and, under the action of a water pump, the water is separated and distributed to the various spray pipes 320 at the bottom of the box body 100. Impurities on the sieve plate 210 below are removed through the spray head, and attachments are cleaned.

[0033] After the preliminary separation of impurities and waste liquid by the solid-liquid separation mechanism 200, most of them will fall directly. In order to achieve a better treatment effect, a first screen 104 and a second screen 105 are set at the bottom of the box 100. The sieve holes of the sieve plate 210 are larger than the sieve holes of the first screen 104, and the sieve holes of the first screen 104 are larger than the sieve holes of the second screen 105. A purification chamber is formed between the first screen 104 and the second screen 105. The wastewater entering the purification chamber has relatively few granular impurities. In order to further A drug delivery pipe 106 and an output pipe 107 are provided on 100. The drug delivery pipe 106 is used for adding drugs, such as flocculants, adsorbents, and bactericidal drugs that can remove organic matter in wastewater. Specifically, they can be directly purchased on the market and added. There is no restriction on the drugs. Purification reaction is carried out in the purification chamber, and sediments will be produced, which will fall between the second screen 105 and the bottom plate. After purification in the purification chamber, it can be discharged through the output pipe 107. The discharged wastewater can also be subjected to subsequent purification treatment again to meet the discharge requirements.

[0034] In order to facilitate the discharge of sediment, a slanted guide plate 108 is provided at the bottom of the second screen 105 and the box 100. It is particularly noted that the screen plate 210, the first screen 104 and the second screen 105 in the drawings are all visible screen holes, which are conventional hole-shaped structures with different diameters.

[0035] The workflow of this utility model is as follows:

[0036] Wastewater residue is added into the box body 100 through the feeding port 101, and the driving cylinder 232 is started to drive the cam column 220 and the sieve plate 210 to move up and down, thereby achieving the movement of the wastewater residue on the sieve plate 210 to separate the solid and liquid, and reduce the clogging of the sieve holes of the sieve plate 210 by impurities. After the solid-liquid separation, the wastewater without large impurities falls down, and is separated into solid and liquid again under the action of the first sieve 104, and the reagent is added into the purification chamber to purify the wastewater. After purification, it is transferred out through the output pipe 107, and the purified sediment is accumulated through the guide inclined plate 108, and is discharged in a centralized manner after reaching a certain amount.

[0037] When the equipment does not need to be operated, the water pump is started so that the water in the water tank 310 can spray downward to clean the attachments on the sieve plate 210 .

[0038] The utility model arranges two inclined sieve plates 210 in a box body 100, arranges a cam column 220 between the two sieve plates 210, and arranges a lifting assembly 230 at the bottom of the cam column 220, so that wastewater residue is put into the box body 100 to pass through the sieve plates 210 for solid-liquid separation. The structure is simple in design and easy to operate, and a purification chamber is also arranged at the bottom of the box body 100, so that the wastewater after solid-liquid separation can be purified, and the interaction of solid-liquid separation and purification can reduce the impact on the environment after discharge.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
