The present disclosure relates to a field of sewage treatment, specifically a sewage treatment device for household garbage.
Garbage is a waste article which loses use value and cannot be used. Moreover, the garbage is an important link for material circulation, and is a solid or a fluid substance which is not required or is useless. Toxic gas is unavoidably generated due to incineration of the garbage, and the incineration of the garbage further harms living bodies. Most cities study a method of reducing garbage generation and also encourage resource recycling. With continuous development of social economy, a living level of people is continuously improved. The present garbage treatment mode causes headaches for many families. Most household garbage is treated by a garbage treatment device, but the present garbage treatment device has the following defects:
Most of the present garbage treatment device crushes garbage generated in daily life of the families and then dehydrates and separates the crushed garbage. This mode can simply carry out simple treatment on the garbage. With improvement of the living level, purchasing power of people is gradually increased. The garbage may contain small articles made of iron materials, a cutter head of a crusher may be worn during crushing the garbage, which reduces working efficiency of the cutter head and a service life of the cutter head. As a result, recycling rate of scrap iron is low, and resource waste is caused. Water containing a large amount of mixed impurities and sludge is discharged after solid-liquid separation, and environmental pollution is caused. A use effect is not ideal.
In view of the prior art, the present disclosure provides a sewage treatment device for household garbage.
The sewage treatment device for household garbage of the present disclosure is provided with a machine body, a stirring cavity and a storage box. A first motor and electromagnets are turned on to enable a stirring shaft to stir garbage, so that iron materials in the garbage are adsorbed. Then the iron materials are storaged in the storage box. Recovery value for a scrap iron market is high. Compared with conventional garbage treatment devices, the sewage treatment device for household garbage not only prolongs service lives of blades, but also recycles, reprocesses and uses the scrap iron to avoid resource waste and environmental pollution. Thus, usability of the sewage treatment device for household garbage is improved.
The sewage treatment device for household garbage of the present disclosure performs flocculation when crushed garbage falls into an interior of a flocculation cavity of the sewage treatment device for household garbage. Water content separated from the garbage contains a large amount of mixed impurities and sludge. The mixed impurities and the sludge are discharged, which causes environmental pollution. The sewage treatment device for household garbage separates large-particle impurities and the sludge in the sewage and then treats the large-particle impurities and the sludge, which reduces environmental pollution caused by directly discharging the sewage. The primarily filtered sewage is filtered step-by-step through three layers of filter plates, Impurities in the sewage are effectively filtered, and the filtered water is retained for recycling. By cooperating with removing the iron materials in the garbage through stirring, completing rate of garbage recycling and sewage purification is high, environmental pollution caused by the sewage is reduces, and a use of users is facilitated.
The present disclosure will be further described with reference to the drawings and embodiments.
In order to make the technical means, creative features, achievement goals and effects achieved by the present disclosure easy to understand, the present disclosure will be further described below in conjunction with specific embodiments.
