Mobile soil steam sterilizer

Abstract

The invention provides a mobile soil steam sterilizer which outputs steam intermittently, that is, when a needle is inserted into the soil, the steam is output to sterilize and disinfect the soil; when the needle is pulled out, the sterilizer is automatically closed, so that steam waste is avoided. The mobile soil steam sterilizer comprises a pulse combustion steam generating device arranged on a frame and a steam disc connected to the frame through a lifting device; the steam disc comprises a steam pipeline and a steam disinfecting needle inserted into the soil; the steam outlet of the pulse combustion steam generating device is communicated with the steam pipeline; the steam disinfecting needle comprises a sleeve and a needle tube; the upper portion of the need tube provided with a steam inlet extends into the sleeve, and the lower portion of the need tube provided with a steam exhaust port extends out of the sleeve; the needle tube is movably arranged in the sleeve up and down; when the needle tube moves to the upper portion, the inner space on the upper portion of the sleeve is communicated with the inner space of the needle tube through the steam inlet; when the needle tube moves to the lower portion, the inner space on the upper portion of the sleeve is not communicated with the inner space of the needle tube; and the inner space on the upper portion of the sleeve is communicated with the steam pipeline.

Description

technical field [0001] This technology relates to a mobile soil steam sterilizer, specifically a pulsating combustion type soil steam sterilizing machine, which uses a pulsating combustion engine as a heat source to generate steam, and passes the steam into the soil through a steam pan to sterilize the soil Sterilize. Background technique [0002] CN105031678A discloses a soil steam sterilizer, which has a steam generating device and at least one steam pan arranged on the frame of a crawler vehicle; the steam pan is located in front of the frame and can move up and down and left and right relative to the frame. connected to the frame; the steam pan includes a hollow steam pan body and an injector connected to the lower part of the steam pan body and communicated with the steam pan body; the steam outlet of the steam generating device communicates with the steam pan body. The applicant found in use that when the injector was not inserted into the soil, water and steam would ...

AI Technical Summary

Problems solved by technology

The applicant found in use that when the injector was not inserted into the soil, water and steam would also flow out of the injector, resulting in waste of steam; in addition, not only steam would be ejected from the steam outlet of the steam generating device, but also a large amount of water would flow out of the injector. High-temperature water flows out from the steam outlet, which not only causes waste of water, but also reduces the temperature of the steam, and the disinfection effect is not good; when the syringe is inserted into the ground, especially the hard ground, it is difficult to insert, and the depth of the insertion into the ground is not deep
