Problems solved by technology

However, when this kind of equipment is used for domestic waste pulping, the pulping effect is not ideal due to the complex components such as stones, fine sand and plastic bags that are not easy to be shredded in domestic waste.
Traditional homogenization equipment cannot separate ingredients such as stones, fine sand, and plastic bags that are not easy to be shredded from organic matter that needs to be pulped. The slurry after pulping cannot meet the requirements of subsequent sections, and hard objects such as stones are easy to Wears out the blades in the equipment, causing problems such as high equipment maintenance fees and costs

Embodiment Construction

[0018] refer to figure 1 An example of application of the device and method is illustrated.

[0019] First, pour water into the homogenizing tank through the water inlet, and when the water level reaches half of the height of the homogenizing tank, slowly add domestic garbage that needs to be homogenized through the feeding port, the liquid-solid ratio is 10:1, and the water and domestic After the garbage is added, adjust the stirring speed of the motor to 70r / min. After stirring for 6 minutes, the heavy materials in the domestic waste, such as stones, will gradually enter the heavy material storage groove, and the fine materials in the domestic waste, such as fine sand, will pass through the fine materials. The outlet plate enters the bottom outlet area. At this time, the pneumatic valve 1 and the pneumatic valve 2 are opened by the PLC controller, and the fine materials in the domestic garbage are removed through the pipeline, and the valve is closed after 30 seconds. Then ...

Abstract

The invention relates to a device and a method for homogenizing domestic garbage. The device comprises a motor, a stirring shaft, a water inlet, a feed inlet, a homogenization tank, a homogenization blade, a residue storage area, a residue water outlet, a scraping plate, a fine material outlet plate, a heavy material storage groove, four pneumatic valve pneumatic valves, two adjustable grab buckets, a PLC controller and the like. To the domestic garbage in the invention, organic substances in the domestic garbage are crushed and homogenized by the change of the stirring rotational speed, the opening and the closing of the pneumatic valves and the use of the grab buckets, and inorganic residues can be synchronously separated. The homogenized material has uniform granularity, and the material and water form homogenate with favorable dispersibility.

Description

technical field [0001] The patent of the present invention relates to a homogenizing device and method, in particular to a homogenizing device and method for pretreatment of domestic waste. Background technique [0002] At present, about 2 / 3 of the cities in China have fallen into the predicament of domestic garbage siege. The annual output of urban domestic garbage in my country is close to 150 million tons, and most of them are piled in the open air, which not only affects the urban landscape, but also seriously affects the health of urban residents. Household garbage has become a thorny issue in urban development. [0003] In order to protect the living environment and ecological environment of human beings, the disposal of domestic waste is becoming more and more important. Fermenting domestic waste to generate biogas, and then burning biogas to generate electricity are the main treatment processes for urban domestic waste recycling. However, domestic waste must be pret...
