The drier is mainly composed of upper cavity, wind-box, base, fluidized bed plate, etc. The upper cavity and wind-box form upper body, and the base is lower body. The upper and lower bodies are connected by means of flat spring and helical spring. Vibration isolation is realized through rubber buffer between lower body and foundation. Box vibration exciter is mounted on the rear part of wind-box Box vibration exciter produces exciting horizontal force by motor through belt driving, so that the drier vibrates with certain frequency through effect of flat spring. The vertical force combined with the hot air passing through the nozzle board casts the material up, and mike it in the state of fluidization; at the same time the horizontal force transports the material forward at a certain speed, and the meterial will pass the weir and come out from the discarge funnel, and finish the drying. Wind cowls are fully distributed on fluidized bed plate, so as to prevent the product from falling into wind-box at the time of stopping, and horizontal air current is produced to ensure even fluidization of material. The charge level in the drier may be adjusted by overflow weir.
GZS系列雙質體振動流化床干燥機 / GZS series double mass vibration fluidized bed dryer
干燥機主要由上腔、風箱、底座、流化床板等組成。上腔和風箱組成上質體,底座為下質體,上、下質體之間通過板彈簧和螺旋彈簧相連,下質體與基礎間通過橡膠緩沖墊隔離振動。風箱后部裝有箱式激振器箱式激振器由電機通過皮帶傳動,產生水平方向激振力,經板彈簧(共振簧)作用,使干燥機以一定的頻率振動,垂直方向的分力與通過噴嘴板的熱空氣一起將噴嘴板上的物料拋起,使物料處于流化狀態,而水平方向的分力使物料以一定速度向前輸送,經溢流堰和出料斗排出,從而完成干燥作業。流化床板上布滿風帽,防止產品在停車時掉入風箱內,并產生水平氣流,確保物料流化均勻。干燥器內料位可由溢流堰調節。
該機具有以下特點:
1.流態化均勻穩定,無死床和吹穿、壁面堆積、溝流、騰涌現象,可獲得均勻的干燥制品
2.本機采用分離拖動方式,運轉平穩,維修方便,噪音低,設備壽命長;
3.可調性好,料層厚度和物料在機內停留時間均可調節
4.避免產品在停車時掉入風箱內,減少產品與干燥器底板接觸和過熱;
5.作業環境清潔,可連續作業;
6.高頻率的振動使熱風分布更均勻,提高了熱風與濕物料的傳熱效率,節能效果好。
The machine has the following features:
1. Fluidization state is even and stable, there is no phenomenon of dead bed or blow breaking, wall sticking, channeling or over-flowing Evenly dried product may be gained
2. Separation driving mode is adopted for the machine, the operation is stable. the maintenance is convenient the noise is low and the service life of equipment is long
3. The adjustability is well, feed layer thickness and the staying time of material in the machine may be adjusted
4. Product is prevented from dropping into wind-box at the time of stopping, so as to reduce the contact between product and drier base plate and any overheating
5. The working envirenment is clean continuous working may be realized
6. Frequent vibration evens the distribution of the hot wind, promoting the heat trasfer rate between the hot wind and wet material. which increases the energy-saving effect
Our product has been widely applied in the fields of petrochemistry, fine chemicals, medcine, food, grain and cooking oil, feeding stuffs, salt marine products processing and superfine drying. It can lower the water content from 78% to 0.59
廣泛適用于石油化工、精細化工、醫藥、食
品、糧油、飼料、鹽業、海產品加工及超細微干燥等
領域,可以將初始含水量78%的產品干燥至0.5%。
該機實現了用一臺該機代替幾臺普通振動床串聯使用的情況,降低了設備投資及工程造價,同時先進的振動結構保證大型振動床寬度、長度方向上同步振動,解決了普通雙電機振動床的偏流、溝流問題,避免了靜止流化床的局部死床、壁面堆積、溝流、騰涌等問題。
This machine can take palce of several ordinary vibration beds connected in series, lowering the investment and the project cost Meanwhile, the advanced vibration structure makes sure that the large bed vibrates synchronously horizontally and vertically, solving the problems of drifting and channeling that are common when using double-pump vibration bed, which can also avoid the static fluidized bed' s defects, such as part dead bed, wall deposit, channeling overflowing, etc
