TECHNICAL FIELD

[0001] The utility model relates to aquatic technology field, concretely is a foam separator for aquaculture. BACKGROUND

[0002] Now in aquatic economic animal cultivation, suspended particulate matter will be produced, and part of organic matter will be dissolved in water. The farm usually uses the foam separator to separate the impurities in the water, and the foam separator separates the foam through the air floatation. In the process of using the foam separator, ozone is usually added to achieve the sterilization effect. In addition, the bubbles produced after the decomposition of ozone will also produce air floatation effect. However, in the process of bubble rising, part of the water in the existing foam separator does not contact with the foam, so that the function of quickly cleaning and separating the part of water cannot be realized.

[0003] Therefore, the utility model provides a foam separator for aquaculture to solve the above problems. UTILITY MODEL CONTENTS

[0004] The technical problem to be solved by the utility model is that in the process of bubble rising, part of the water in the existing foam separator does not contact with the foam, so that the function of cleaning and separating the part of water cannot be realized, resulting in poor cleaning and separating effect.

[0005] The utility model provides the following technical scheme: a foam separator for aquaculture, including the separator body, the bottom in the separator body is installed with the foam generator, a group of water inlet pipes are installed on the side wall of the separator body, and the water outlet pipe is communicated with the lower end of the water inlet pipe on the side wall of the separator body; the water inlet pipe is inclined to the foam generator;

[0006] The upper part of the separator body is a foam separation zone, and the foam collection module is arranged on the outer wall of the separator body at the corresponding position of the foam separation zone, and the foam collection module is communicated with the foam recovery area.

[0007] The foam collection module includes a transition ring, the inner circle of the transition ring is connected with the upper end of the separator body, and the outer circle of the transition ring is connected with a recovery ring; the recovery ring is communicated with a recovery pipe.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] During operation, foam separators typically incorporate ozone for disinfection and sterilization. The decomposition of ozone produces bubbles, which also contribute to flotation. However, in existing foam separators, some water remains uncontacted during bubble rise, hindering the rapid cleaning and separation of this portion. Flotation principle: Flotation generates numerous tiny bubbles in the water. These bubbles adhere to small suspended particles in the wastewater, forming a "bubble-particle" complex with an overall density less than water. The suspended particles rise to the surface with the bubbles, forming foam scum, thus separating the suspended solids from the water.

[0029] Addressing the technical problem that in existing foam separators, some water does not come into contact with the foam during the bubble's ascent, thus failing to achieve effective cleaning and separation of this portion of water and resulting in poor cleaning and separation performance, this disclosure provides a foam separator for aquaculture. (Refer to...) Figure 1 The separator includes a separator body 1, and a foam generator 2 is installed at the bottom inside the separator body 1; a set of water inlet pipes 3 are installed on the side wall of the separator body 1, and a water outlet pipe 7 is connected to the lower end of the water inlet pipes 3 on the side wall of the separator body 1; the water inlet pipes 3 are inclined toward the foam generator 2.

[0030] Above the separator body 1 is a foam separation zone 4. A foam collection module 5 is provided on the outer wall of the separator body 1 at the corresponding position of the foam separation zone 4. The foam collection module 5 is connected to the foam recycling area.

[0031] When it is necessary to clean impurities from the aquaculture water, open the inlet pipe 3 and close the outlet pipe 7. At the same time, turn on the foam generator 2. The aquaculture water entering through the inlet pipe 3 flows into the foam generator 2 and comes into contact with the foam generated by the foam generator 2. After that, the water in the inlet pipe 3 continues to flow towards the foam generator 2 and gradually fills the separator body 1. The foam initially generated by the foam generator 2 rises synchronously with the water. After the water fills the generator body, stop the inlet pipe 3. The initially generated foam carries the impurities in the water to the foam separation zone 4 and then flows into the foam recycling zone through the foam collection module 5 for collection.

[0032] Meanwhile, the foam generator 2 continues to work, and the foam moves upward from the bottom of the water body to clean the water body again. The foam carrying impurities passes through the foam separation zone 4 and enters the foam collection module 5 in sequence; then the inlet pipe 3 and the outlet pipe 7 are opened; the water body in the aquaculture area is cleaned in a cycle.

[0033] refer to Figure 2 and Figure 3 The foam collection module 5 includes a transition ring 51, the inner ring of which is connected to the upper end of the separator body 1, and the outer ring of which is connected to a recovery ring 52; the recovery ring 52 is connected to a recovery pipe 53.

[0034] After the foam moves to the foam separation zone 4, it spreads to the transition ring 51. Then, after being squeezed by the continuously generated foam, the foam spreads from the transition ring 51 to the outer recycling ring 52. After that, it is recycled through the recycling pipe 53 to the foam recycling area for recycling.

[0035] refer to Figure 4The transition ring 51 includes an upper connecting plate 511 and a return plate 512; the inner ring of the upper connecting plate 511 is connected to the outer ring of the separator body 1, and the outer ring of the upper connecting plate is connected to the recovery ring 52; the return plate 512 is disposed on the outer wall of the separator body 1 at the lower end of the upper connecting plate 511; there is a gap between the upper connecting plate 511 and the return plate 512, and a return channel 513 is provided on the upper connecting plate 511.

[0036] When foam carries impurities into the foam collection module 5, the water on the upper edge of the separator body 1 may move towards the foam collection module 5 along with the bubbles due to factors such as shaking. As a result, after the bubbles move to the upper connecting plate 511, the water that moves to the upper connecting plate 511 flows from the upper connecting plate 511 through the return channel 513 to the return plate 512, and then flows into the separator body 1 along the return plate 512. This can reduce the pressure in the foam recovery area and extend the cleaning cycle of the foam recovery area.

[0037] The upper armature plate 511 is arc-shaped with the arc-shaped opening facing downwards.

[0038] The arc-shaped design of the upper armature plate 511 can further prevent water from flowing out of the upper part of the separator body 1 through the upper armature plate 511. The return plate 512 is inclined towards the separator body 1.

[0039] Figure 4 Point a in the diagram is the inlet connecting the return plate 512 and the separator body 1. The return plate 512 is inclined so that the water flowing into the return plate 512 can re-enter the separator body 1.

[0040] The outer ring of the water inlet pipe 3 is connected to a water inlet ring 31, and a water inlet 32 ​​is provided on the water inlet ring 31.

[0041] By setting up an inlet ring 31, sewage can flow into the separator body 1 simultaneously through multiple inlet pipes 3.

[0042] A conical cover plate 6 is installed above the foam collection module 5.

[0043] By setting the cover plate 6 to a conical shape, when there are many substances that need to be cleaned in the sewage in the breeding area, a lot of foam will be generated. If the foam overflows onto the cover plate 6, the foam can flow into the recycling ring 52 along the inner wall slope of the cover plate 6 for recycling.

[0044] An antifoaming needle 54 is installed at the recycling tube 53.

[0045] After the foam passes through the upper connecting plate 511 and reaches the recycling ring 52, before flowing into the recycling area through the recycling pipe 53, the foam is first defoamed by the defoaming needle 54 to facilitate subsequent recycling.

[0046] A detachable filter structure is installed at the water inlet 32.

[0047] Wastewater from the aquaculture site is transported to the inlet 32 ​​through a water pipe. At the inlet 32, the wastewater undergoes preliminary filtration through a filter structure. Afterward, the wastewater enters the separator body 1 through the inlet ring 31 and the inlet pipe 3. After prolonged use, the water pipe carrying the wastewater at the inlet 32 ​​can be disassembled to expose the filter structure, which can then be disassembled for cleaning or replacement.

[0048] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
