Description

A dryer for disposing domestic waste

technical field

The utility model relates to the field of garbage treatment, in particular to a dryer for treating domestic garbage.

Background technique

Reuse of resources has always been a hot topic for human beings. The slogan of saving resources has gradually penetrated into the hearts of the people. Only through the recycling of resources can we truly achieve environmental protection and energy saving. The use of municipal solid waste to make fuel is the essence of resource reuse. One of the means. With the development of my country's urbanization process and the improvement of population level, more and more urban garbage is produced, and the growth rate has exceeded 5%-8% in recent years. More than 200 of the 660 cities in the country have been surrounded by garbage, and large garbage mountains have appeared. This kind of garbage mountain not only pollutes the environment and takes up a lot of land resources, but also may produce toxic gases, endangering urban residents. How to properly dispose of urban waste and realize the harmlessness, reduction and energy conversion of waste has become a major problem faced by countries all over the world. At this stage, the drying of garbage includes artificial drying and drying by drying units using coal and fuel oil as fuel; these drying methods have poor effects, high costs, serious pollution, and are difficult to promote; existing drying equipment designed for this purpose, But these equipment structures are very complicated, and it is difficult to dry and the efficiency is not high. The application number is 201120027742.5, which discloses a dryer for domestic waste treatment, which is composed of a hot blast furnace part and a dryer part; the dryer includes a feeding system, a drum, a transmission system, and a discharging system; one end of the drum is It is connected to the feeding system, and the other end is connected to the discharging system; the drum is connected with the transmission system, and the drum is supported on the transmission system; the utility model uses the hot air generated by the hot blast stove to heat the garbage in the drum, and uses the lifting material in the furnace to The board continuously raises the domestic garbage and contacts it with the hot air. This dryer has the following defects: 1. The humidity increases after the hot air absorbs water during drying, which affects the drying efficiency. As a gas, the hot air flows randomly in the drum, and the control is difficult. 2. The hot air flow speed is faster in the part where the garbage is looser in the drum, and the hot air flow speed is slower in the denser part of the garbage, which makes it difficult to dry the garbage in each part of the drum in the same degree, which affects the final drying effect.

Contents of the invention

The utility model provides a dryer for processing household garbage, aiming to overcome the disadvantages of low drying efficiency and poor drying effect of the dryer.

The utility model adopts the following technical solutions:

A dryer for processing domestic waste, including a drum, a support table and a heating pipe, the drum is rotatably and obliquely arranged on the support table through supporting wheels, and the two ends of the drum correspond to form a feed end and a discharge end end, the heating pipe is arranged in the drum; the heating pipe includes a main body, a plurality of three-dimensional spiral blades and a plurality of bifurcated pipes connected with the main body, and the plurality of blades pass through the bifurcated pipe The bodies are arranged on the main body at intervals along the length direction of the main body, the main body is arranged in the drum and both ends extend to the outside of the drum.

Further, the number of helical turns of the blades is 0.7, the helical directions of two adjacent blades are opposite and they are arranged on opposite sides of the main body, and the main body is located at the central axis of the blades.

Further, both the discharge end and the feed end are provided with sealing covers rotatably connected to the drum, wherein the sealing cover of the discharge end is provided with a discharge port and an air exhaust port, and the sealing cover of the above feed end is provided with a stuffing funnel.

Further, the inner wall of the drum is provided with a plurality of plates for frying garbage.

As can be known from the description of the utility model structure, the utility model has the following advantages:

One, the utility model includes a drum, a support platform and a heating pipe, wherein the heating pipe is arranged in the drum, and the two ends of the heating pipe extend to the outside of the drum; the heating pipe includes a main body, a plurality of three-dimensional spiral blades and A plurality of bifurcated pipe bodies communicated with the main pipe body, and a plurality of vanes are arranged on the main pipe body at intervals along the length direction of the main pipe body through the bifurcated pipe bodies, and the main pipe body is located at the central axis of the blades. When in use, put hot water, distilled water or steam into the heating pipe, and the heat in the heating pipe passes through the main body and the bifurcated pipe body to heat and dry the garbage in the drum in a distributed manner. It has the advantages of high drying efficiency and uniform drying degree of garbage everywhere in the drum. When the drum rotates, the bifurcated pipe body and blades can stir and disperse the garbage, so as to ensure that all garbage can be dried and the drying effect is ensured.

Second, in the present utility model, the helical directions of two adjacent blades are opposite and are arranged on opposite sides of the main body. During the process of the garbage from the inlet end to the outlet end, the blades with different spiral directions have different action directions on the garbage, and the garbage is stirred in different directions to improve the stir-frying effect of the blades.
