Detailed description

Description： Disc dryer is a highly efficient continuous conduction type continuous drying equipment, its unique structure and working principle of the decision that it has high thermal efficiency, low energy consumption, small footprint, configuration is simple, convenient control, good operating environment characteristics. Widely used in chemical, pharmaceutical, pesticide, food, feed, agricultural products processing industries drying operation. Practice in the industry to use well received. Can be divided into atmospheric pressure, sealed, vacuum three types; 1200,1500,2200,3000 and other specifications; A (carbon), B (exposure to the material part of the stainless steel), C in B, based on the increase in steam pipes , stainless steel shaft and frame, barrel and cap lined with stainless steel) three types of material, dry area of ​​4 ~ 180m2, total of hundreds of types of products, and provide a matching auxiliary equipment to meet the user the need for drying of various materials. Features:
(一) control easy applicability
1 by adjusting the thickness of material, spindle speed, rake arm number, type and size can rake leaves drying process to achieve the best.
2. Jieke pass into each dish drying medium heat or cold medium, the material for heating or cooling, the material is heated evenly, temperature control is accurate and easy.
3 material residence time can be precisely adjusted.
4 the flow of a single material, no back-mixing phenomenon, uniform drying, stable quality, do not need to mixing. (二) simple, easy
1 dryer car, parking operation is very simple.
2.Stop feeding after delivery of material to rake leaves quickly emptying the material inside the dryer. 3 by a special large format view door mirrors, the device can be carried out very carefully cleaning and observation.

(三) low energy consumption 1 material layer is very thin, spindle speed is low, the material needs of the power transmission system is small, less power consumption. 2. to transfer heat to dry, high thermal efficiency, low energy consumption.

(四) operating environment, recyclable solvents, dust emissions to meet the requirements 1 atmospheric model: Because of the low flow rate, and distribution equipment, compete with the humidity is low, dust is difficult to float to the top of the device, so the top of the humidity and exhaust emissions in the mouth with almost no dust. 2 closed-type: with a solvent recovery unit, can be easily recovered in the wet gas in organic solvents. Solvent recovery simple, high recovery rate for flammable, explosive, toxic and easy oxidation of the material, available nitrogen as the carrier gas closed-cycle wet, so that safe operation. Especially for flammable, explosive, toxic materials dry. 3. Vacuum-type: in a vacuum tray dryer operations, especially for heat-sensitive materials dry.

(五) Easy installation, small footprint 1. Dryers whole factory, the overall transport, just hoisting, positioning is very easy to install. 2 result of the dry plate layer-type arrangement, vertical installation, even if a large drying area, the area is also small.

Application: Dry distillation of pyrolysis reaction of calcined cooling (一) Organic chemical products (二) inorganic chemical products (三) the pharmaceutical, food (四) of feed, fertilizer

Technical characteristics: (一) the dry plate 1 Design pressure: typically 0.4MPa, up to 1.6MPa. 2 Maximum operating pressure: normal ≤ 0.4MPa, up to 1.6MPa. 3. Heating medium: steam, hot water, oil, dry plate temperature is 100 ℃ heating using hot water, 100 ℃ ~ 150 ℃ ≤ 0.4MPa when saturated with water vapor or superheated steam heated, 150 ℃ ~ 320 ℃ when the use of thermal oil heating.

(二) material transfer system 1 Spindle speed: 1 ~ 10 turn points, electromagnetic, or frequency conversion stepless speed. 2. Rake arm: each dried plate with 2 ~ 8 fixed to the spindle on the rake arm. 3 rake leaves: splices in the rake arm, can fluctuate to maintain contact with the disk, in various forms. 4 grinding roll: the caking and the need to crush the material in place with addition of grinding roll, you can enhance heat transfer and drying process. (三) shell With atmospheric pressure, sealed, vacuum three types 1 pressure-type: cylindrical or octagonal cylindrical, with overall and off the two structures. You can import and export director said heating medium in the shell, the shell can be outside. 2 closed type: cylindrical shell, can withstand 5Kpa pressure, heating medium can import and export of the main channel in the shell, you can also shell outside. 3. Vacuum-type: cylindrical shell, designed to pressure-0.096Mpa, export director said heating medium in the shell. (四) Air heaters Generally used when configuring fan to prevent moist air into the host affect the drying effect. Principle: Wet material from the feeder continuously added to the dryer on top of the first layer of the dry plate, with a leaf rake for rotary movement of the rake arm, turned to rake arm continuously copied material. Material along the spiral flow index plate surface drying, drying in a small disk of material was transferred to the outer edge of the disk material in the big move to the inside and from the mouth into the middle of the blanking plate under a layer of small dried. Alternating up and down the size of the dry plate, the material to continuously flow through the dryer. Blow drying tray pass into the heating medium, heating medium in the form of saturated steam, hot water and heat transfer oil, heating medium into one end of the dry plate, derived from the other side. Has a layer of dry material from the last shell fell on the bottom of the dry plate, was finally transferred to rake leaves out of the discharge port. Wet steam escaping from the material from Moisture in the mouth on the roof of discharge, vacuum type disc dryer in wet steam from the vacuum pump on the roof of the mouth out. Discharged from the bottom of the dry material can be directly packaged. With addition of fins through the heater, solvent recovery condenser, bag filter, back-mixing of dry material body, fan and other auxiliary equipment, can increase the production capacity of its dry, dry paste and heat-sensitive materials can be easily recovered solvents, and can be pyrolysis and reaction operations.
