Calcium hypochlorite, commonly known as bleaching, is commonly used in the bleaching process in chemical production, and plays an important role in industrial production due to its rapid onset of action and outstanding bleaching effect. However, because it is a strong oxidant, it is extremely harmful to people. It must not be used for other purposes outside the industry. When using it, it should also pay attention to its own protection and avoid corrosion. In addition, its large amount of volatilization also has strong carcinogenicity, and it must be noted when storing.
Special dryer for calcium hypochlorite Product introduction:
Boiling fluidized bed, which is composed of air filter, heater, bubbling bed host, cyclone separator, bag filter, high-pressure centrifugal fan and operation console. Due to the different nature of dry materials, it can be equipped as needed. Considering that the cyclone separator and the bag filter can be selected at the same time, or one of them can be selected. Generally, the larger specific gravity such as the granule and the granular material are dried, only the cyclone separator is selected, and the small specific gravity is small granular and powdery. The material needs to be equipped with a bag filter, and a pneumatic feeding device and a belt conveyor are available for selection.
The granular solid material is fed into the fluidized bed dryer by the feeder, and the filtered clean air is heated and sent to the bottom of the fluidized bed by the blower to contact the solid material through the distribution plate to form a heat exchange of fluidization to achieve gas-solidity. After the material is dried, it is discharged from the discharge port, and the exhaust gas is discharged from the top of the boiling bed through the cyclone dust collector group and the bag filter to recover the solid powder and then emptied.
Vapor, electric and hot blast stoves can be used (according to user requirements).
Special dryer for calcium hypochlorite Working principle:
The clean hot air is distributed into the bed through the valve plate, and the wet material entering from the feeder is boiled by the hot air. Since the hot air is in extensive contact with the material, the heat and mass transfer process is enhanced, so it can be dried in a short time. If the continuous type is used, the material enters from one end of the bed, and after boiling for several tens of seconds to several minutes, it automatically flows out from the other end of the bed. This equipment is generally operated under negative pressure.
Special dryer for calcium hypochlorite
Drying of pharmaceuticals, chemical raw materials, food, grain processing, and feed. Such as: raw material medicine, tablet granules, Chinese medicine granules, health food, beverage granules, corn germ, feed, plastic resin, citric acid and other powder materials dry and dehumidification. The applicable material particle size is generally 0.1 to 6 mm, and the optimum particle size is 0.5 to 3 mm.
Maintenance and maintenance procedures and inspection work for high-efficiency boiling dryers:
1. Check whether the components of the high-efficiency boiling dryer are in good condition and disinfect according to the high-efficiency boiling dryer disinfection procedure. When the equipment is running, the hands, feet and objects must not protrude into the cone to prevent accidents. When the upper part is sampled, it is necessary to stop first. If it is found that there is a hard foreign object entering the machine, it should be stopped in time, and then driven after being discharged.
2. Check whether the air compressor of the high-efficiency boiling dryer is lubricated. Whether there is cooling water in the gas tank, if any, drain it.
3. Install the cloth bag and other components, turn on the power, check whether the automatic and manual switches are flexible, and set the relevant data.
4. Advance the prepared wet granules into the high-efficiency boiling dryer in time, open the high-efficiency boiling dryer for drying, and strictly control the amount of dry wet granules to not exceed 100 kg, and control the drying temperature and time.
5. During the drying process, grasp the dry condition of the particles through the window at any time, and control the whole process of drying according to the process rules.
6. After drying, turn off the power of the high-efficiency boiling dryer and pour out the material in the dryer.
7, high efficiency boiling dryer bearing and gear life, generally 2-3 years. The lubrication of the cycloid reducer should be checked regularly. The normal oil level is 1/2-2/3. The new equipment should be changed once after 50 hours of full load operation. Improve equipment hygiene according to the high-efficiency boiling dryer cleaning program.
8. Check the lubricating oil once per shift. If the oil is short, add it in time. The main gearbox, distribution box, gear oil and grease of the drive head part need to be inspected once every six months. Add or replace gear oil and grease as appropriate. The bottom bearing of the screw shaft is washed and removed once after 500 hours of operation. (The new machine is washed and removed once after 100 hours of operation). If it is found to be damaged, it should be replaced in time. Bearings should be strictly checked for grease. Maintain the equipment in accordance with the high efficiency boiling dryer maintenance program.
