Overview of double shaft humidifier

The double shaft humidifier is also called dust humidifier. It is a kind of high-efficiency equipment for humidifying and mixing powder materials. It is suitable for dust humidifying and stirring in coal-fired power stations, such as ash removal and mining. The dual-shaft humidifying mixer uses two symmetrical spiral shafts for synchronous rotation. While conveying powdery materials, uniformly humidifies and stirs the dry powdery materials to achieve the desired humidity (humidified materials do not emit dry ash and It will not leak water droplets.) By controlling the amount of water added, the equipment has reached the appropriate humidity requirements. It has high efficiency, compact structure, reasonable configuration of drive mechanism, stable operation of the whole machine, low vibration, low noise, good sealing, uniform stirring, No dust and other advantages, it is an ideal powdery material humidification and stirring equipment.

Working principle of double shaft humidifier

The dust humidification mixer is equipped with two stirring shafts, and a plurality of fan-shaped stirring blades are distributed on the shaft with a certain spiral angle and pitch. The blades are staggered on the two shafts. The side wall of the casing is equipped with a water inlet pipe and the nozzles are arranged laterally. Water is evenly sprayed from the nozzle on the water inlet pipe, and the two rigid stirring shafts rotate in the opposite direction, so that the fly ash is evenly stirred and transported. The new mixer has made significant improvements in the impeller and the bearing seat, which overcomes the common shortcomings of the twin-shaft mixer, has a low failure rate and a longer service life. The reducer uses a cycloid pinwheel reducer, which has a compact structure, a small footprint, stable transmission, and low noise. The blade is made of alloy tool steel or ceramic blade, which has good wear resistance. The mixer stirs evenly, runs reliably, and is easy to operate and maintain.
The material enters the box from the inlet through the electric air-lock feeder, and the two blades with left and right spirally distributed shafts rotate synchronously, and the humidified material is continuously pushed to the outlet. The machine adopts a multi-groove labyrinth and packing combined shaft seal, which has a reliable seal and light shaft wear. Compared with the drum type humidifier, the double-shaft stirring humidifier has a larger output (200t per hour can be humidified), uniform humidification, reliable work and low maintenance. The special atomizing nozzle and water supply system with adjustable water volume can ensure that the material is humidified evenly and the water volume is moderate. The material of the blades of the double-shaft stirring humidifier is made of high-wear-resistant materials with high wear-resistance. The shaft is made of 45 # steel after quenching and tempering, which is durable. The wallboard is finished by the milling processing center to ensure the precision of gear meshing. Frequency quenching treatment, high surface strength and impact resistance.



Technical Parameters

The dust humidifying mixer is U-shaped. The thickness of the shell can be customized according to the actual needs of customers. The stainless steel humidifying mixer can also be customized. The center distance between the inlet and outlet of the dual-shaft humidifying mixer can be designed and manufactured according to the customer's site conditions. The amount of water can also be adjusted. The twin-shaft humidifier is suitable for humidifying and stirring powdery materials such as fly ash. The twin-shaft horizontal mixer is composed of a motor, a reducer, a casing, a stirring blade, etc., which has high quality and low price, and is durable.
