Problems solved by technology

[0006] The Chinese patent "Spiral Flow Hot Air Dryer" (application number 02149402) discloses a technical route of hot air drying + screw conveying, but this patent uses spiral blades to directly transport the materials to be dried, but has some operational shortcomings: first , the dried material is easy to harden on the surface of the spiral blade, and it is not easy to detach; second, the thick material to be dried cannot be turned, making it difficult to dry quickly inside

Embodiment 1

[0047] Embodiment 1. Novel flush-free toilet

[0048] The original intention of the present invention is to meet the requirements of the Bill & Melinda Gates Foundation to "create the next generation of sanitation facilities" and "reinvent the toilet plan", and to design a toilet that can "run away from the water supply pipeline and indeed kill pathogens; Recycling; low price and easy promotion" "next generation toilet". For the new type of toilet in this example see image 3 . where the reference signs and figure 1 The reference signs in have the same meaning. In this embodiment, the water-containing solid material is feces, and the feed port is a toilet or a squatting pan. Wherein feces refers to stool and / or urine. The feces are not limited to human feces, and may also be animal feces, such as animal feces from poultry farms.

[0049] The new toilet workflow is:

[0050] 1) A group of carrying balls 11 and the feces / urine mixture are stirred and mixed in the agitator...

Embodiment 2

[0055] Example 2. Kitchen waste treatment device

[0056] Kitchen waste is a difficult part of domestic waste. It has a high content of organic matter, breeds bacteria, produces peculiar smell, and is mixed with other recyclable waste, which increases the difficulty of subsequent sorting and treatment.

[0057] Utilize application example 1 of the present invention, and feed port 12 wherein is connected to a pulverizer, kitchen waste-leftovers etc. are pulverized as water-containing solid material to be dried and mixed with carrier balls, and the rest are processed The steps are the same as in Example 1, and then the kitchen waste can be dried and converted into sterilized organic fertilizers.

Embodiment 3

[0058] Embodiment 3. the processing of all the other aqueous solid materials

[0059] Obviously, the water-containing solid materials to be dried are not limited to feces and kitchen waste, but can also be livestock waste from farms, sludge from sewage treatment tanks, lake sludge, waste residue from the food fermentation industry, and Chinese herbal medicines after extracting active ingredients. Waste slag, etc., all can utilize device and method of the present invention to handle.

Abstract

The invention relates to a moisture-containing solid material drying device using carrying balls to assist in drying. The moisture-containing solid material drying device comprises a stirring mixer 7, a spiral conveying dryer 14 and a plurality of carrying balls 11, the stirring mixer 7 is used for stirring moisture-containing solid materials together with the carrying balls, a feed port for the moisture-containing solid materials is formed in the stirring mixer, the spiral conveying dryer 14 comprises an enclosed shell 1 and a spiral conveying blade 2 arranged in the shell, the spiral conveying blade 2 can be driven by a spindle 3 to rotate, a spiral passage 17 is formed between the spiral conveying blade 2 and the enclosed shell 1, a dry air inlet 5 and a moist air inlet 6 as well as a moisture-containing solid material inlet 15 and a dry solid material outlet 16 are formed at two ends of the spiral passage respectively, and the moisture-containing solid material inlet 15 is connected with an outlet of the stirring mixer 7. The invention further relates to a method using the drying device for drying the moisture-containing materials.

Description

technical field [0001] The invention belongs to the field of drying equipment and drying methods. Background technique [0002] Generally speaking, there are two methods for drying water-containing materials (also known as wet materials or materials to be dried). The first is forced evaporation, that is, heating the temperature of the material to 100C under normal pressure, and the water changes from liquid to gas. This phase change process consumes a lot of energy, and its description parameter is latent heat of vaporization. Under one atmospheric pressure (0.1MPa), 100 The latent heat of vaporization of water at ℃ is 2257.2kJ / kg, compared with the specific heat capacity of water is 4.2kJ / kg, in other words, the energy consumed by the vaporization of water is 5 times the energy required to raise the same amount of water from 0C to 100C many. This is the main reason for the high energy consumption of forced evaporation. The typical representative of forced evaporation is t...
