Box bottom of wood tar extracting box

Abstract

The invention discloses a box bottom of a wood tar extracting box, which is a prophase product used to extract wood vinegar vegetable acid, a major component of plant-insecticidal pesticide, from a plant. A hollow brick box bottom of a mother liquid wood tar extracting box is arranged by means of a technology of placing an upper-layer hollow bricks and a lower-layer hollow bricks to form a 3m-long and 2.5m-wide ventilating box bottom of the wood tar extracting box, hollow holes of the upper-layer hollow bricks can realize top-and-bottom ventilation, the hollow holes of the lower-layer hollow bricks are arranged horizontally, a gap, half of the brick length, is reserved between lines of the lower-layer hollow bricks, and therefore the hollow brick box bottom can realize front-and-back ventilation and left-and-right ventilation; and moreover a combustion nest layer, an interlayer and dead angle cannot occur during the retorting process.

Description

technical field [0001] The invention relates to a preliminary product for extracting plant insecticide and pesticide main components from plants, wood vinegar phytoacid, and the bottom of a mother liquor wood tar extraction box. Background technique [0002] In the past wood tar production and extraction, a simple metal container was used to put the raw materials into it for dry distillation. It did not have a special bottom of the box. This kind of bottom of the box without a special setting, the ventilation is uneven, and the heat and air flow cannot be fully ventilated in the box. The flow of the carbon dioxide makes it impossible to heat the raw materials evenly in the nest layer, interlayer and dead corner during the retort process, which will eventually cause poor retort effect, waste a lot of raw materials, and cause poor product quality, labor-intensive, Time-consuming and material-consuming phenomenon. Contents of the invention [0003] In order to solve the abov...
