Description

A seedling fumigation furnace based on automatic control and its working method

technical field

The invention belongs to the application field of automation control, and in particular relates to a seedling fumigation furnace based on automation control and a working method thereof.

Background technique

In the environment of continuous cultivation of domestic flower seedlings, how to reduce the losses caused by quarantine pests of flower seedlings, how to improve the cultivation quality of flower seedlings, carry out on-site quarantine treatment for transported flower seedlings, and preventively eliminate quarantine pests have become common concern of the people. Since the quarantine pests of flower seedlings cannot be ignored in the factors affecting the quality of cultivation, how to reduce the losses caused by quarantine pests of flower seedlings is a key topic of research and discussion by the government, school research institutes and related enterprises, and it is also a topic of concern at home and abroad. One of the key points that ecological security issues are highly valued.

In the current prior art, the removal method of quarantine pests on flower seedlings is mainly realized by chemical treatment in the field and chemical fumigation or spray control in the warehouse. However, most of the existing quarantine treatment methods cannot implement immediate on-site treatment of small batches of flower seedlings due to high fumigation site requirements, large fumigation batches, and fixed fumigation points. The safe use leads to a large amount of medicament used, and because the fumigant is slow to disperse poison, there is heavy environmental pollution, and the risk of poisoning of operators cannot be effectively avoided.

The fumigation furnace is a kind of energy conversion equipment. The energy input to the fumigation furnace includes chemical energy and electric energy in the fuel, and the fumigation furnace outputs steam, high-temperature water or organic heat carrier with certain heat energy.

At present, steam fumigation furnaces and hot water fumigation furnaces usually use coal as fuel. Because coal has a high calorific value and less volatile matter, it is beneficial to provide air supply conditions and has a relatively simple structure. The structure of a typical coal-fired steam fumigation furnace is: a combustion chamber is provided in the furnace body, and heating pipes are arranged and connected around the combustion chamber. The two sides of the rolling grate are respectively connected with transmission chains and connected with the transmission shaft and the power machine. The steam fumigation furnace with this structure can only use coal as fuel, which has heavy pollution and low efficiency of coal combustion.
