Mixing tank type ash digestion machine

The working principle of the mixing tank ash digestion machine:

Considering the shortcomings of the lime digestion machine in the past, our company has an environmentally friendly lime digestion machine in the mixing tank. The process is as follows: quicklime enters the environmentally friendly mixing tank lime digestion machine from the feed inlet, adds water, and then undergoes double helix digestion. At this point, a large amount of dusty steam will be generated. The lime digester generates negative pressure in the water tank through a fan, and then draws external steam containing dust into the water tank through an induced draft pipe. In this way, dust settles in the water, and steam turns into water in the water. The sediment generated in the water tank is mixed with external water, and then pumped out by a water pump before adding water to the lime digester in the mixing tank. Through this method, dust removal and the recycling of wastewater after dust removal have been achieved. Resolve the issues of low utilization rate and secondary water pollution in wet dust removal.

The steam containing dust enters the water tank through multiple dust removal screens, each with multiple small holes, allowing the steam to actually enter the water through the small holes. In this way, the water droplets blown through each small hole will not be carried away by dust, thus achieving the characteristic of dust removal. This machine mainly adopts the method of rotating instead of stirring for ash removal. There is a sieve hole at the rear of the inner cylinder of the ash crusher, and the lime blocks come into contact with the water inside the inner cylinder for digestion. Lime milk flows into the feed inlet through sieve holes and exits through the lower discharge outlet. Discharge undigested excessive combustion and combustion lime from the slag removal device at the tail of the outer cylinder. The ash making machine has a reasonable structural device, easy operation, high production capacity, low labor intensity, and is suitable for any quality of lime.

The output shaft of the deceleration motor is connected to the impeller shaft through a coupling. The impeller shaft is supported by a bearing seat and extends to the sealing tube and the digester housing. Through the interior of the water tank, the impeller shaft is located inside the digester housing, and the feed pipe opening extends to the top of the water tank. The inlet of the multi-stage flow aid fan is connected to the top of the digester housing, and the outlet of the multi-stage flow aid fan extends from the top opening of the water tank to the water tank; There is a water pump in the water tank, and multiple nozzles are installed on the water supply pipe, which is connected to the water supply pipe at the top of the digester shell through the inlet pipe; The discharge port is installed at the end and bottom of the digester housing. This utility model can reduce and increase the pressure of the lime digester in the mixing tank, solving the problems of severe steam pollution and uneven feeding of the digester during the process of quicklime digestion.

Mixing tank ash digestion machine; Structural characteristics:

1. This device has the characteristics of an independent and reasonable dust removal system, compact equipment structure, etc

2. A set of spiral feed propellers is designed at the feed inlet of the digester to prevent the backflow of steam and dust generated during the digestion process. The formed steam and dust are concentrated at the dust outlet and enter the dust removal equipment, reducing corrosion and damage to surrounding equipment and providing a good working environment. At the same time, it also improves the utilization rate of quicklime. The equipment adopts a covered water addition device, with uniform water addition and lime digestion.

3. This device adopts double helix digestion, with good digestion effect, uniform feeding, no spraying, no blockage, and adopts a dual axis stirring form. It has functions and effects such as stirring, crushing, and self-cleaning. The blade and mixing method ensure that the quicklime is evenly mixed with water, the reaction is complete, and the blocks generated during the crushing reaction process are broken.

4. This device is equipped with steam and dust ports, which can be connected to dust removal pipes and can handle the dust, steam, and gas generated during the digestion process. After use, the reuse of waste dust and quicklime can be achieved, and there is no dust pollution in the on-site environment. The lime digestion function of the mixing tank can be reasonably configured with the required water to achieve the full digestion effect of quicklime.

5. The dual axis blades are made of high manganese material, and the heat-treated alloy material has the function of self-cleaning bonding material; Avoid sticking lime, blade wear, and even shaft breakage to extend the service life of the equipment.

6. The double axis mixing tank lime digestion machine can be improved in relevant dimensions according to enterprise requirements, and automatic configuration can also be added according to enterprise requirements.

7. The blades of the spiral shaft of this device are embedded with hard alloy, which has a long service life.
