Description
Technical field
The utility model belongs to chemical field, exactly is the drying and crushing all-in-one.
Background technology
The preparation process of chemical products powder body material (as: non-ferrous metal carbonate, hydroxide etc.) generally comprises: prepare burden, react and make, wash, filter (Separation of Solid and Liquid), drying, pulverizing (oxide needs roasting) mixing, finished product.Dry, pulverizing is two very important critical processes.
Drying equipment can be divided into by different criterions: (1) heat transfer type is divided: conduction heating, Convective Heating, several microwaves of radiation heating, dielectric heating; (2) dry type is divided: pallet, rotary drum, fluid bed, air-flow and spray thing drying; (3) time of staying classification of product in equipment: the time of staying, short (less than 1 minute) had flash distillation, spraying, rotary drum drier, the time of staying long (greater than 1 hour) tunnel, small handcart and belt dryer etc. are arranged.
Pulverizer generally is divided into mechanical type pulverizer (machine mill), airslide disintegrating mill (pneumaticcracker), grinder (grinding machine) and four big classes of Lowtemperaturepulverizer (low-temperature mill).
Can with dry, pulverize and in an equipment, finish, undoubtedly to enhance productivity, benefit, reduce investment in fixed assets, energy-saving and cost-reducing have a good meaning.At present, can accomplish that drying, the equipment of pulverizing one mainly contain spray-drying and rotary flashing drying two kind equipments.Spray-drying requires material solid-to-liquid ratio little (be that solids is few in the material, moisture content is many), can only use in specific material, and energy consumption is big.Rotatingandflashstreamingdrier is early than the eighties, and Chinese Ji Hua company dyestuff factory and dying of Dandong factory introduce from Denmark An Haidanuo (ANHYDRO) company, is used for the drying of intermediate and dyestuff; Digesting and assimilating on the basis of foreign technology the beginning of the nineties, realizes production domesticization.
Though it is very extensive that Rotary Flash Drying is used, its theoretical research is also very backward, and it is rarely found that system introduces the document of hydrodynamics, heat transfer and mass transfer of rotation rapid drying device all sidedly.Present amplification design and operating parameter determine mainly to depend on experiment and experience.
The dried active zone of Rotary drying is very thin, gas velocity is (90-100m/s) near wall the rotation gas-bearing formation, and it is very low in the center of hothouse gas velocity, be difficult to granule materials is taken out of hothouse, in fact, not being fully used in dry run in the central area, has only the inner space of the equipment that just can effectively utilize than the version of minor diameter.So, adding air flow panting degree, restriction " dead band " could intensified drying process.
Summary of the invention
The purpose of this utility model is exactly the problem at above-mentioned existence, and provides a kind of material spin intensity height, crush efficiency good, can be according to the time of the reasonable particle size control drying and crushing of material, thus the drying and crushing all-in-one that cuts down the consumption of energy.
It is by feeder, air-heater, the cyclone drying crush tower, whirlwind rewinding tower, tower gathers dust, air-introduced machine is formed, described cyclone drying crush tower, by charging aperture, the hot blast import, agitator and discharging opening are formed, charging aperture is located at the middle part of the body of cyclone drying crush tower, connect with feeder, the hot blast import is located on the bottom sidewall of body, link with air-heater, discharging opening is located at upper part of body, be connected with whirlwind rewinding tower, whirlwind rewinding tower, the tower that gathers dust links to each other successively with air-introduced machine, it is characterized in that: described agitator is located at the bottom of body, by shaft, stir axle sleeve, the body sledge, the shaft sledge, stirring arm is formed, stirring arm is a ladder type, the shaft sledge is above stirring arm, and stirring arm and shaft sledge all are fixed on the shaft, and the shaft sledge intersects with the body sledge comb formula that is fixed on the body;
Shaft is arranged with air-cooling device;
Described discharging opening is the discharging opening of two to three band valves, is arranged above and below, and body is provided with adjustable top cover and annular ring washer, and they are adjustable up and down, and adjustable top cover is being opened above the discharging opening of valve, and annular ring washer is below the discharging opening of opening valve;
But body also is provided with the observation window of free switch;
The outlet of air-introduced machine is provided with heat exchanger.
During work, feeder advances wet stock in the tower, under the sucking action of the body sledge of agitator, shaft sledge, the stirring of stirring arm, the hot blast that blows into, air-introduced machine, material fully mixes with hot blast, spiral making progress, and dry fine grained is little because of centrifugal force, carried secretly by hot blast, a wet coarse granule part directly falls, and a part is upwards blocked by ring-like ring washer along the tower wall, falls down and continues to pulverize drying; If raw meal particle size is little, need the dry time long, adjustable top cover and ring-like ring washer are adjusted upward, open the discharging opening of top, on the contrary then opposite; See through the observation window interior material grinding situation of observing tower at any time, window switch dynamics is judged positive negative pressure condition in the tower according to the observation, adjusts and blows or the air inducing amount.
The utility model is pulverized dry all-in-one, body sledge and shaft sledge comb formula intersection have been improved crushing effect, the ladder type stirring arm is accelerated the wind speed rotation, adjustable top cover and ring-like ring washer have reasonably been controlled time and the granularity of material in tower, reduced energy consumption, ring-like ring washer can block the dry good material of not pulverizing and improve product quality, dwindled simultaneously the diameter of tower relatively, solved in the center of hothouse gas velocity low, be difficult to granule materials is taken out of hothouse, can not be fully used in dry run in central area (dead band), has only the problem that just can effectively utilize the inner space of equipment than the version of minor diameter; Can increase the internal diameter of tower, improve output; Observation window can be observed, convenient for maintaining, can reconcile air-supply, air inducing amount according to the switch dynamics again, and tube is single practical; Heat exchanger can utilize waste heat.
