Crushing device for treating impurities filtered out from sewage

Abstract

The invention discloses a crushing device for treating impurities filtered out from sewage, and relates to crushing equipment. The crushing device comprises a crushing box, wherein a motor is fixedlyconnected with and arranged at the top part of the crushing box; a horizontal rotating shaft is fixedly connected with and arranged at the output end of the motor; a driving bevel gear is fixedly connected with and arranged on the horizontal rotating shaft; a driven shaft is rotatably connected with and arranged at the top part of the crushing box; a driven bevel gear is fixedly connected with andarranged at the top part of the driven shaft and is engaged with the driving bevel gear; a universal coupling is fixedly connected with and arranged at the bottom part of the driven shaft; a crushingshaft is connected with and arranged below the universal coupling; crushing blades are fixedly connected with and arranged at the bottom part of the crushing shaft; a cam is fixedly connected with and arranged at the outer side of the horizontal rotating shaft; and a longitudinal ejector rod is slidably connected with and arranged at the upper left part of the crushing box. The crushing device provided by the invention is simple in structure and convenient to use, can fully and thoroughly crush impurities filtered out from sewage in the crushing box when in use, facilitates more sufficient reutilization of the filtered-out impurities, improves the recovery rate of energy, has good effect and high crushing efficiency, and is worthy of popularization.

Description

technical field [0001] The invention relates to a crushing device, in particular to a crushing device for treating impurities filtered out of sewage. Background technique [0002] With the acceleration of urbanization in our country, urban water shortage is becoming more and more serious; at the same time, the discharge of urban domestic sewage is increasing, and the increasingly serious water pollution reduces the use function of water bodies, which makes the inherent contradiction between supply and demand of water resources sharper. The shortage of water resources has become a serious restrictive factor for the sustainable development of the national economy and society. In view of the actual situation of water resource shortage in our country and the disadvantages of centralized treatment and recycling of domestic sewage, it is proposed that appropriate decentralized treatment and recycling of domestic sewage is a necessary supplement to centralized sewage treatment and...

Problems solved by technology

[0004] Although there is not much dirt in domestic sewage, most of them are rice grains, melon peels, and domestic organic garbage. These dirt can be completely reused, and the amount of accumulation is large. It is a huge waste, and most of these impurities cannot be directly reused. Although these filtered substances can be used for direct biogas fermentation, without treatment, the fermentation time will be long, and some of the filtrates are difficult to ferment. Therefore, it is necessary to process the filtered substances. Crushed and reused

Although the existing crushers are relatively effective in crushing the impurities filtered out of sewage, there are still some crushers that have poor crushing effects when crushing the filtrates, and it is difficult to meet the crushing requirements.
