Description

Technical Field

[0001] The utility model relates to a source water filtering and purifying device for an eel pond breeding system. Background Art

[0002] The water used in traditional eel farming is relatively rough. Since the water is not filtered, the breeding stream water is often affected by protozoa such as wheelworms and Ichthyophthirius, as well as impurities from leaves, which causes eels to often become diseased during the breeding process, which is not conducive to eel farming. In addition, if there is heavy rain, it will affect the water change in the breeding pond, thereby affecting the growth of the eels. Utility Model Content

[0003] The utility model improves the above-mentioned problem, that is, the technical problem to be solved by the utility model is to provide a source water filtering and purification device for an eel pond breeding system, which is beneficial to filtering and purifying the initial breeding water, reducing the occurrence of diseases in the breeding process, and ensuring the growth of eels.

[0004] The utility model is constructed as follows: it comprises an upstream dam, a first raw water filtering structure, a second raw water filtering structure, a reservoir, a third raw water filtering structure and a microfilter which are sequentially arranged along the aquaculture water conveying direction.

[0005] Furthermore, the first, second and third raw water filtration structures all include a filter layer, a sand filter layer and a stone filter layer arranged in sequence from top to bottom.

[0006] Furthermore, a heating tank is provided at the output end of the microfiltration machine.

[0007] Furthermore, the filter screen of the microfilter is 600-1200 meshes.

[0008] Furthermore, the upstream dam and the first raw water filtration structure, the first raw water filtration structure and the second raw water filtration structure, the second raw water filtration structure and the reservoir, the reservoir and the third raw water filtration structure, and the third raw water filtration structure and the microfilter are all connected via a transmission channel.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure and is easy to use. The raw water in the upstream dam is filtered through the filter layer, sand filter layer and stone filter layer of the first raw water filter structure, the filter layer, sand filter layer and stone filter layer of the second raw water filter structure, and then is transported to the reservoir. When the raw water in the reservoir is output, it is sequentially filtered through the filter layer, sand filter layer and stone filter layer of the third raw water filter structure and the microfilter, and then is transported to the heating tank for heating. The filtered raw water is heated to 28°. The utility model sets the filter layer, sand filter layer and stone filter layer of the first, second and third raw water filter structures, and can heat the raw water to 28°C. Impurities such as leaves can be filtered out. The first and second raw water filtration structures can perform preliminary filtration on the raw water transported from the upstream dam to the reservoir. The third raw water filtration structure can filter some leaf impurities, protozoa, etc. produced in the reservoir due to storage time. At the same time, the microfiltration machine can effectively filter out protozoa such as wheelworms and Ichthyophthirius, thereby filtering and purifying the water for eel farming, greatly reducing the occurrence of protozoan parasites, reducing the use of drugs, avoiding emergency use of eel drugs, and effectively improving the breeding and growth efficiency of eels. The setting of a larger reservoir can ensure uninterrupted water supply for eel farming and ensure normal feeding and production of eels. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0013] Example: Figure 1~2 As shown, in this embodiment, a source water filtration and purification device for an eel pond aquaculture system is provided, comprising an upstream dam 1, a first raw water filtration structure 2, a second raw water filtration structure 3, a reservoir 4, a third raw water filtration structure 5 and a microfilter 6, which are arranged in sequence along the aquaculture water delivery direction.

[0014] The above-mentioned water reservoir is large in size, and the amount of water stored in the water reservoir should be three times the amount of water required for aquaculture, which can effectively meet the water demand of the eel breeding pond for three days and avoid the inability to change water in the breeding pond due to weather reasons.

[0015] The above-mentioned microfiltration machine is prior art.

[0016] During operation: the raw water in the upstream dam is filtered through the filter layer, sand filter layer and stone filter layer of the first raw water filtration structure, the filter layer, sand filter layer and stone filter layer of the second raw water filtration structure, and then transported to the reservoir. When the raw water in the reservoir is output, it is filtered through the filter layer, sand filter layer and stone filter layer of the third raw water filtration structure, and then filtered by the microfilter. It is then transported to the heating tank for heating, and the filtered raw water is heated to 28°.

[0017] By setting the filter layer 7, sand filter layer 8 and stone filter layer 9 of the first, second and third raw water filtration structures, impurities such as leaves in the raw water can be filtered out. The first and second raw water filtration structures can perform preliminary filtration on the raw water transported from the upstream dam to the reservoir. The third raw water filtration structure can filter some leaf impurities, protozoa, etc. produced in the reservoir due to storage time. At the same time, by setting a microfiltration machine, protozoa such as wheelworm and small melon weed can be effectively filtered out, thereby filtering and purifying the water for eel farming, effectively improving the farming and growth efficiency of eels.

[0018] In the embodiment of the utility model, the first, second and third raw water filtering structures all include a filter layer 7, a sand filter layer 8 and a stone filter layer 9 which are sequentially arranged from top to bottom.

[0019] The sand filter layer is a filter layer composed of sand, and the stone filter layer is a filter layer composed of stone.

[0020] In the embodiment of the utility model, a heating pool 10 is provided at the output end of the microfilter, and a conveying channel is also provided between the microfilter and the heating pool.

[0021] In the embodiment of the present invention, the filter screen of the microfilter is 600-1200 mesh.

[0022] In the embodiment of the utility model, the upstream dam and the first raw water filter structure, the first raw water filter structure and the second raw water filter structure, the second raw water filter structure and the reservoir, the reservoir and the third raw water filter structure, and the third raw water filter structure and the microfilter are all connected through a conveying channel.

Unless otherwise stated, the above words have no special meaning.

[0025] At the same time, if the above-mentioned utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0026] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.
