Film drying machine arranged on multistage cold air jet machine

Abstract

The invention discloses a film drying machine arranged on a multistage cold air jet machine. The film drying machine comprises a tank body, a lower mounting cover and an upper mounting cover, whereina hollow fiber filament film filter core is arranged in the tank body; an air inlet pipe is arranged on the lower mounting cover; an air outlet pipe is arranged on the upper mounting cover; a steam exhaust pipe is arranged on a side wall of the tank body; an air inlet cavity which is communicated with the air inlet pipe is formed between the hollow fiber filament film filter core and the lower mounting cover; a dry gas exhaust cavity is formed between the hollow fiber filament film filter core and the upper mounting cover; a steam exhaust pipe is arranged on a side wall of the tank body; the hollow fiber filament film filter core and an inner wall of the tank body are provided with steam outer side volatilization cavities which are communicated with the steam exhaust pipe. According to thefilm drying machine, a steam center volatilization channel and a peripheral dry gas channel are formed, so that the compressed air filtering and drying efficiency can be increased; moreover, the drygas channel facilitates drying of the hollow fiber filament film filter core, so that the use efficiency of the hollow fiber filament film filter core is improved.

Description

technical field [0001] The invention belongs to the technical field of cold air jet machines, and in particular relates to a membrane dryer arranged on a multistage cold air jet machine. Background technique [0002] During the machining process of metal, a large amount of heat will be generated due to cutting between the tool and the workpiece. If it is not cooled, it will have many adverse effects on the machining accuracy and the physical and chemical properties of the workpiece; the existing cooling methods include coolant cooling and air cooling. Cooling; air cooling has the advantages of convenient use, storage, cleaning and handling, and will not cause adverse consequences to the environment and the health of the operator, and the cost of use and handling is low. Therefore, air cooling metal machining (dry processing) generally received attention. [0003] In the prior art, the compressed air enters the drying tower for drying after passing through the secondary filt...

Problems solved by technology

[0003] In the prior art, the compressed air enters the drying tower for drying after passing through the secondary filtration (1 μm filter + 0.01 μm filter), and the interior of the drying tower is adsorbed by granular adsorption materials processed by many chemical dusts In the process of production and use, some particles will be broken and dust will be generated due to repeated pressure changes in the filling and drying container; Exhausted into the air, it seriously threatens the health of operators and other personnel; in fact, the cost of isolating this kind of dust is very high. In the actual cooling process, the compressed air must be directly blown at a relatively large pressure (0.1Mpa) and flow rate. In the processing area, adding a dust isolation net will only reduce the air pressure and flow rate at the outlet, and the dust isolation net also needs to be replaced frequently; the trouble and cost increase caused by this is also what the user does not want to see of
