Flame type deiinted cotton seeds processing technology and dedicated combustion furnace thereof

Abstract

The invention relates to a method for removing pile of cotton seed and relative device, especially a flame-type pile removing method and special burning furnace. The method at least comprises a combing process and a pile burning process, wherein, the burning furnace comprises a burning room which contains a smoke outlet and a seed inlet, and a seed outlet at the bottom. The burning furnace is arranged with a burner with flame injector. The fresh seed treated by said invention can be fed into the furnish process, or treated by inventive method for two or three times then be fed into the furnish processes. The invention can be used as pretreatment of other process, as acid process to reduce the acid consumption.

Description

Technical field: [0001] The invention relates to a cotton seed delinting processing technology and its special equipment, in particular to a flame type cotton seed delinting processing technology and a special combustion furnace. Background technique: [0002] Delinting of cotton seeds before sowing in cotton planting is a very important treatment technology. The current cotton seed delinting processing is generally divided into two types, one is friction delinting processing, such as the cottonseed delinter disclosed in Chinese Patent No. 02291810.8, the cottonseed delincher disclosed in 95227333.0, and 98217179.X discloses an improved cottonseed. Dehairing machines belong to this type of process equipment. This type of method mainly uses forced dry grinding, which is easy to produce a waxy layer on the surface of the seeds, which is not conducive to the absorption of water and nutrients by the seeds. After sowing into the ground, the germination time of the seeds is prolonged, ...

Problems solved by technology

The metering acid treatment process consumes a lot of acid, and the acid cannot be recycled and reused. If it is discharged, it will cause serious environmental pollution, high processing costs, and different batches of seeds have different cashmere content, so the acid ratio must be constantly changing , the process control is very difficult, making it difficult to grasp the residual acidity of the seeds, and it is difficult to guarantee the quality of the seeds

As disclosed in Chinese patent 88103743.5, the cottonseed foam acid delinting technology adopts the chemical raw material Ninar and OS-15 or both to directly mix first to make a sulfuric acid foaming agent, and then uses industrial concentrated sulfuric acid, sulfuric acid foaming agent, water Measured separately, mixed directly in a certain proportion to make foam acid to treat the seeds, and then neutralized the residual acid with ammonia. Using this method, if the acid ratio is too high, the seeds will be burned and the germination rate will be affected. If the acid ratio is insufficient, There will be excess velvet

Although the excess acid treatment process is easy to grasp the residual acidity and the amount of residual velvet of the seeds, the seeds generally do not exceed the standard of residual acid, and the waste acid can be recycled and reused, but it is easy to produce a certain degree of damage to the seeds when the seeds pass through the centrifuge. Physical damage, while the short fleece that is taken off still contains a large amount of acid. If it is not handled properly, it will also cause certain environmental pollution. In addition, the severe corrosion of acid on mechanical equipment will greatly increase equipment maintenance costs and increase production costs. It is also a chemical method. a big problem to deal with
