Automatic fumigation cabinet

Abstract

The invention relates to an automatic fumigation cabinet, which is characterized in that: a plurality of heating cavity bodies are arranged inside a cabinet shell, a sealing door of the heating cavity bodies is arranged on the front surface of the cabinet shell, and valves, a vacuum pump and pipelines are distributed inside the cabinet shell; compressed air pipes which are respectively connected with each pneumatic valve are connected onto an air compressor air supply pipe in parallel, the compressed air pipe of each pneumatic valve is controlled by an electromagnetic valve to open and close,the electromagnetic valve is controlled by an electrical control cabinet, and the electrical control cabinet is assembled with the cabinet shell into a whole; a central processing unit (CPU) judges the ambient temperature according to a signal of a temperature sensor, and if the ambient temperature is lower than 5 DEG C, a heating device is automatically controlled to work so as to heat the heating cavity bodies; and the device has an automatic dispensing function, an automatic fumigation function and an automatic exhaustion function and also has a semi-automatic concentration detection function, a computer display screen is used for substituting a mechanical-type button panel to control and operate, work flow can be worked out and adjusted on the machine according to the requirement, andthe work state of each cavity can be immediately displayed.

Description

technical field [0001] The invention relates to the technical field of chemical treatment, in particular to an automatic fumigation cabinet, which is applied to fumigation treatment research. Background technique [0002] With the acceleration of global economic integration, my country is playing an increasingly important role in international trade. Today, countries no longer simply use "tariff barriers" to compete, but use "technical barriers" with higher technical content to restrict competitors. In recent years, some countries often set up "technical barriers" to China's export products under the pretext that my country's export products carry harmful organisms that threaten the safety of the importing country, restricting the development of my country's foreign trade. Quarantine treatment is an important measure to deal with inbound and outbound goods to prevent the invasion and spread of alien pests. Therefore, strengthening the scientific research on quarantine t...

Problems solved by technology

Unavoidable serious damage to the health of the operator

Some fumigants have high vaporization temperature and boiling point, and are not easy to vaporize in winter in the north, so fumigation tests cannot be carried out

At the same time, the existing non-automatic fumigation method is inefficient and seriously delays the progress of the test
