A kind of p-toluidine production feeding device

Abstract

The invention discloses a feeding device for p-toluidine production, which comprises an adjusting feeding component, a feeding control component, and a cleaning and blowing component. Sweeping assembly, in the present invention, the operator can use the control system to control the cylinder to drive the driving slider, the connecting slider, the T-section slider, and the feeding main pipe to slide up and down in turn, so that the feeding main pipe can be located above the feed port of the reactor. Different heights are convenient for frequent feeding operations. When feeding, control the bottom of the feeding main pipe to be close to the feed inlet of the reactor. When performing reactor maintenance or other operations, raise the feeding main pipe to avoid the influence of the feeding main pipe operating space.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a p-toluidine production feeding device. Background technique [0002] In the existing chemical production technology, the method of manual feeding is mostly used to put the reaction materials into the reactor. Large manufacturers will layer the production plant in the way of building or steel frame construction in the production plant, not only It can save the area occupied by the equipment, and is also conducive to the improvement of production efficiency. In the factory building, a storage tank is installed on the high storage layer, and a reaction kettle is installed on the lower production layer. With manual assistance, the materials in the storage tank It can be efficiently conveyed down to the reactor through pipe fittings, but no matter which way, for the feeding operation of the reactor, manual close contact with chemical materials is required, which is harmf...

Problems solved by technology

[0002] In the existing chemical production technology, the method of manual feeding is mostly used to put the reaction materials into the reactor. Large manufacturers will layer the production plant in the way of building or steel frame construction in the production plant, not only It can save the area occupied by the equipment, and is also conducive to the improvement of production efficiency. In the factory building, a storage tank is installed on the high storage layer, and a reaction kettle is installed on the lower production layer. With manual assistance, the materials in the storage tank It can be efficiently conveyed down to the reactor through pipe fittings, but no matter which way, for the feeding operation of the reactor, manual close contact with chemical materials is required, which is harmful to health, and chemical manufacturers need to produce different products to supply market demand , after the production reaction of a product in the reactor, it is necessary to thoroughly clean the residue in the reactor and the feeding pipe. In order to avoid mutual contamination of materials, different materials require specific feeding pipes. After the production is completed, disassemble The materials that come down from the feeding pipes are mixed together and are easy to oxidize in the air. In the production process of p-toluidine, iron powder is easy to oxidize. Oxidation after use will affect the product quality when used next time, and the mutual confusion between the feeding pipes will also affect the quality of the produced products. It is necessary to centrally clean the feeding pipes to facilitate the next use. When changing the production product , the feed switching work of the material requires the operator to operate at close range, which is laborious and harmful to health, so people need a p-toluidine production feeding device to solve the problems in the prior art
