Description

Technical Field

[0001] The utility model belongs to the technical field of biogas slurry storage, and particularly relates to a concentrated liquid storage tank for biogas slurry concentration. Background Art

[0002] Biogas slurry is a by-product after anaerobic fermentation of livestock and poultry breeding manure and sewage to produce biogas. It is rich in nutrients such as nitrogen, phosphorus, and potassium and is a high-quality liquid fertilizer. However, with the increase in breeding volume, problems such as large biogas slurry production, difficult local digestion, and high long-distance transportation costs have become prominent. Therefore, the reduction and resource utilization of biogas slurry have become the focus of industry research. Currently, there are problems in the current biogas slurry concentration technology, such as high concentration cost, large energy consumption, and difficulty in large-scale application. To overcome these problems, people have begun to research and apply various biogas slurry concentration and storage technologies, such as membrane separation and negative pressure concentration technology, and have designed related devices and equipment, such as biogas slurry storage ponds and biogas slurry concentration and purification devices. The application of these technologies and devices aims to improve the fertilizer efficiency of biogas slurry, reduce transportation costs, and eliminate the harm caused by microorganisms contained in biogas slurry to the environment.

[0003] The existing concentrated liquid storage tanks for biogas slurry concentration have the following problems when in use:

[0004] 1. During the use of the traditional concentrated liquid storage tank for biogas slurry concentration, there is a heat insulation protection cover on the outside of the concentrated liquid storage tank for biogas slurry concentration. Most of the heat insulation protection covers only have a layer of sunscreen paint on the outer surface. Although this has a certain sunscreen effect, when encountering strong sunlight, the sunscreen effect will be a bit worse.

[0005] 2. During the use of the traditional concentrated liquid storage tank for biogas slurry concentration, fermentation occurs inside the concentrated liquid storage tank for biogas slurry concentration, filling the inside with gas, which will cause the storage tank to deform and expand, reducing the durability of the storage tank. Content of the Utility Model

[0006] The purpose of the utility model is to provide a concentrated liquid storage tank for biogas slurry concentration to solve the technical problems raised in the background art.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A concentrated liquid storage tank for biogas slurry concentration.

[0008] Preferably, a vacuum groove is opened on the inner side of the protection cover, a vacuum plate is arranged inside the protection cover, the vacuum plate is inserted into the vacuum groove, a heat insulation groove is opened on the inner side of the protection cover, heat insulation cotton is arranged inside the protection cover, the heat insulation cotton is inserted into the heat insulation groove, and a protection cover is arranged on the top of the protection cover.

[0015] 1. For this concentrated liquid storage tank for biogas slurry concentration, by providing heat insulation cotton and a vacuum panel inserted inside the protective cover, the protective cover has a strong sun protection effect. When encountering strong sunlight, the first layer of heat insulation cotton has a significant heat insulation effect. It consists of many tiny bubbles, and these bubbles can effectively prevent the transfer and flow of heat, thus keeping the body or the interior of an object warm in cold weather and preventing external high temperature from entering the interior in hot weather. When reaching the second vacuum panel, the insulation panel is light in weight and has good fire resistance. Its heat preservation effect far exceeds that of conventional polystyrene boards, extruded boards, and polyurethanes, and the construction is simple.
