Description
Technical Field
The invention relates to a preparation method of fomesafen, belonging to the technical field of pesticide preparation.
Background
The fomesafen is suitable for broad-leaved weeds such as soybean, peanut field control abutilon, acalypha australis, bidens pilosa, amaranthus, ragweed, rape, shepherd's purse, goosefoot, dayflower, stramonium, black nightshade, morning glory, teff, herba polygoni orientalis, purslane, sida acuta, amaranthus, cassia tora, humifuse euphorbia herb, cleavers, echinacea purpurea, physalis, sesbania, sonchus, sow thistle, caltrop, axil, nettle, cocklebur, xanthium sibiricum and the like. It can also be used for preventing and killing broad-leaved weeds in orchards and rubber plantation.
The existing fomesafen reacts in a reaction kettle under a certain temperature condition, the whole reaction kettle is generally heated by the existing reaction kettle heating device, so that the consumption of heat energy is caused, the heating area can not be adjusted according to the actual reaction condition, and the manufacturing cost of the product is improved.
Disclosure of Invention
The invention aims to overcome the defects and aims to provide a preparation method of fomesafen, which reduces the production cost of products.
The technical scheme adopted by the invention is as follows: the preparation method of fomesafen comprises the following steps of: the kettle comprises a kettle body, the lateral wall of the kettle body forms an interlayer structure, a heating wire is arranged in the interlayer in a clamping manner, the lower end of the heating wire is fixedly arranged, and the upper end of the heating wire is arranged in a floating manner.
Furthermore, the upper end of the heating wire is connected to an insulating plate, and the insulating plate is connected with a pushing device for pushing the insulating plate to move up and down.
Further, the pushing device is a plurality of air pipes symmetrically and uniformly distributed and connected with the insulating plate, the air pipes are arranged in a hollow cavity, the insulating plate can move up and down by introducing or extracting air into the air pipes, and the upper ends of the air pipes extend out of the kettle body.
Furthermore, the heating wire is wound in the kettle body, and a certain telescopic allowance is left.
Furthermore, the outer wall of the interlayer is coated with a heat insulation layer, and the inner wall of the interlayer is a heat conduction layer.
The invention has the advantages that: the heating wire adopts a setting mode that the longitudinal length is adjustable, the longitudinal length of the heating wire is adjusted according to the actual reaction condition, the heat utilization efficiency of the heating wire is improved as much as possible, and the consumption of heat energy is reduced, so that the production cost of a product is reduced, and the heating wire has good practical performance.
Drawings
FIG. 1 is a schematic structural view of a reaction vessel according to the present invention.
In the figure, 1 is a kettle body, 2 is an air pipe, 3 is an insulating plate, 4 is a heating wire, 5 is a heat insulating layer, and 6 is a heat conducting layer.
Detailed Description
The preparation method of fomesafen comprises the following steps of: the kettle comprises a kettle body, the lateral wall of the kettle body forms an interlayer structure, a heating wire is arranged in the interlayer in a clamping manner, the lower end of the heating wire is fixedly arranged, and the upper end of the heating wire is arranged in a floating manner.
Furthermore, the upper end of the heating wire is connected to an insulating plate, and the insulating plate is connected with a pushing device for pushing the insulating plate to move up and down.
Further, the pushing device is a plurality of air pipes symmetrically and uniformly distributed and connected with the insulating plate, the air pipes are arranged in a hollow cavity, the insulating plate can move up and down by introducing or extracting air into the air pipes, and the upper ends of the air pipes extend out of the kettle body.
Furthermore, the heating wire is wound in the kettle body, and a certain telescopic allowance is left.
Furthermore, the outer wall of the interlayer is coated with a heat insulation layer, and the inner wall of the interlayer is a heat conduction layer.
The invention will be further explained below for a better understanding of the invention: when the reaction kettle is used, according to the volume condition of materials in the reaction kettle, the gas is introduced into the gas pipe or extracted from the gas pipe, the insulating plate is pushed to move upwards or downwards, so that the longitudinal length of the heating wire is changed, heat generated by the heating wire is gathered in the area where the materials are located, the temperature can quickly reach the temperature required by the reaction, meanwhile, the consumption of heat energy is reduced, and the reaction kettle has good practical performance; furthermore, the heat insulation layer is coated on the outer wall of the interlayer, and the heat conduction layer is coated on the inner wall of the interlayer, so that heat energy generated by the heating wire can be better gathered in the direction of the inner wall of the reaction kettle, the heat energy utilization rate is further improved, and the ineffective consumption of the heat energy is reduced.
