However, the spin flash dryer in the above form has a problem in use, 95% of the material is discharged after passing through the cyclone separator, but about 5% of the material inevitably enters the bag-type dust collector, and in order to avoid waste, the 5% of the material needs to be collected again and mixed with the discharged material of the cyclone separator again, and then is bagged, so the operation flow is more lengthy, the production efficiency is affected, and the energy-saving effect is poor. For this reason, it is required to improve it to solve the above-mentioned problems.

Disclosure of Invention

The utility model aims to overcome the defects and provide the rotary flash evaporation dryer with high drying and discharging efficiency, so that the rotary flash evaporation dryer has more energy-saving and environment-friendly benefits.

The purpose of the utility model is realized as follows:

the utility model provides a spin flash dryer, includes cyclone and dust remover, cyclone sets up in the dust remover, and cyclone is located the dust remover lower part, cyclone's inlet pipe passes the lower part outer wall of dust remover, cyclone's bottom leakage mouth is located the top of the bottom export of dust remover.

Furthermore, a blanking gap is formed between the outer wall of the cyclone separator and the inner wall of the dust remover.

Furthermore, the dust remover is a bag type dust remover, and a dust removing bag positioned in the dust remover is positioned above the cyclone separator.

Furthermore, a vibration mechanism is installed on the dust remover.

Furthermore, the dust remover is provided with a pulse type oscillating mechanism to form a pulse bag type dust remover.

Furthermore, the cyclone separator passes through a feeding pipe on the outer wall of the dust remover and is communicated to a discharge hole of the classifier, the classifier and the stirrer are respectively arranged at the upper part and the lower part of the dryer, and the stirrer is communicated with the air feeder through a heater and a hot air inlet at the lower part.

Furthermore, a pipeline connected with an upper air suction opening of the dust remover is communicated to the silencer through a draught fan.

Compared with the prior art, the utility model has the beneficial effects that:

the cyclone separator is integrated in the dust remover, so that the discharging of the cyclone separator and the discharging of the dust remover are concentrated at one position, and in the whole working process, the cyclone separator and the dust remover continuously discharge materials continuously, namely, material mixing is carried out synchronously, so that the whole equipment structure is more compact, the required occupied area is smaller, the working efficiency is effectively improved, the working process is simplified, the materials can be discharged from the same outlet and bagged at the same time in hundreds of percent, the production of production enterprises is greatly facilitated, the energy consumption of the operation is reduced, the market competitiveness of the products of the enterprises is improved, and the energy-saving and environment-friendly positive benefits are achieved.
