CN203154906U - Curved screen filter pool facilitating aquaculture - Google Patents

Abstract

The utility model relates to equipment for aquaculture, and in particular relates to a curved screen filter pool facilitating aquaculture. The curved screen filter pool comprises an overflow tank which is connected with a return water pipe, a curved screen, a sewage collection tank which is connected with a sewage drainage pipe, and a curved screen pool, wherein an upper opening of the overflow tank is connected with the upper end of the curved screen; and the lower end of the curved screen is connected with an opening of the sewage collection tank. A screen surface of the curved screen is inclined, return water flows into the screen surface of the curved screen along the overflow tank, and sewage is filtered and scoured to the sewage collection tank at the lower end and is unlikely to gather on the screen surface of the curved screen, so that the filter efficiency of sewage is improved.

Description

A curved sieve filter tank for convenient aquaculture

technical field

The utility model relates to equipment for aquaculture, in particular to an arc-shaped sieve filter pool convenient for aquaculture.

Background technique

Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to release seedlings in small and medium-sized natural waters, and completely rely on natural bait to grow aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and fence farming. High-density intensive farming uses methods such as running water, temperature control, oxygenation, and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as high-density fish and shrimp farming in running water.

In high-density intensive farming, it is necessary to recycle, filter, purify, oxygenate, and sterilize the backwater with dirt in the breeding pond for secondary use, which has achieved the purpose of saving water and maintaining the breeding environment. The current backwater recycling and filtration uses horizontal sieves This kind of screen is easy to store dirt in the mesh area, which makes the filtration difficult and affects the work efficiency. the

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a convenient curved sieve filter tank for aquaculture that improves the efficiency of dirt filtration.

The utility model is realized through the following technical solutions:

A curved sieve filter tank for convenient aquaculture, comprising an overflow tank connected to a return pipe, a curved sieve, a sewage collection tank connected to a sewage pipe, and a curved sieve pool, the upper notch of the overflow tank and the arc-shaped The upper end of the sieve is connected, and the lower end of the curved sieve is connected with the notch of the dirt collection tank.

The curved sieve is arranged along the length direction of the curved sieve filter tank, and reinforcing ribs are arranged at intervals under the curved sieve.

A water pump for outputting filtered water is provided in the arc-shaped sieve pool.

The beneficial effects of the utility model are:

Since it is installed on the curved screen, the screen surface is inclined, and the return water flows into the curved screen surface along the overflow tank, and the dirt is filtered and washed to the dirt collection tank at the lower end. The screen is not easy to store dirt in the mesh area, improving Dirt filtration efficiency.

Description of drawings

Fig. 1 is a front structural schematic view of the utility model.

In the figure: 1. Overflow tank, 2. Reinforcing ribs, 3. Curved sieve, 4. Sewage collection tank, 5. Curved sieve pool, 6. Lifting pump, 7. Sewage pipe, 8. Return pipe.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model includes an overflow tank 1 connected to the return pipe 8, a curved screen 3, a sewage collection tank 4 connected to the sewage pipe 7, and a curved screen pool 5. The upper notch of the overflow tank is connected to the The upper end of the curved sieve is connected, and the lower end of the curved sieve is connected with the notch of the dirt collection tank.

Since it is installed on the curved screen, the screen surface is inclined, and the return water flows into the curved screen surface along the overflow tank, and the dirt is filtered and washed to the dirt collection tank at the lower end. The screen is not easy to store dirt in the mesh area, improving Dirt filtration efficiency.

The curved sieve is arranged along the length direction of the curved sieve filter tank, and reinforcing ribs 2 are arranged at intervals under the curved sieve. Strengthen the strength of the curved screen and improve the life of the curved screen.

A water lifting pump 6 for outputting filtered water is provided in the curved sieve tank. The filtered water can be exported to the next production link.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
