The utility model relates to sulfonated phenolic resin production technical field provides a kind of drying equipment for sulfonated phenolic resin production, including bottom plate, the two sides of bottom plate upper surface symmetry fixedly set with support plate, the inner cavity of two groups of support plates is all opened with rotating cavity, the inside of two groups of rotating cavities is all rotationally arranged with rotating ring, two groups of rotating ring inner cavity are fixedly set with drying cylinder, the utility model is mutually matched by setting threaded feeding pipe, connecting pipe and arc-shaped stirring vane between, heating sleeve is heated to drying cylinder, and the output end of second motor drives rotating lever rotation, and rotating lever drives connecting pipe, arc-shaped stirring vane to sulfonated phenolic resin is stirred, and sulfonated phenolic resin is pushed to the side of threaded feeding pipe, water vapor is discharged outside via one-way exhaust pipe, and the sulfonated phenolic resin that condensation agglomerates will be moved to discharge pipe place by the grinding of threaded feeding pipe, effectively avoid material blockage, improve the practicality and drying efficiency of device.

The invention discloses a pneumatic closed sampling device suitable for sulfonated phenolic resin and a sampling method. The device comprises a mechanism supporting frame, a traction lifting mechanism arranged at the top of the mechanism supporting frame, a lifting closed bin and a control mechanism which are arranged on the mechanism supporting frame, a pneumatic valve arranged at the bottom of the mechanism supporting frame, and an external sampling cup, the pneumatic valve is connected with a sampling hole of the reaction kettle; the bottom of the lifting sealing bin is open, and the lifting sealing bin is in sliding connection with the mechanism supporting frame and can do lifting motion on the mechanism supporting frame. A traction piece of the traction lifting mechanism penetrates through the lifting closed bin, and the bottom of the traction piece is connected with a sampling barrel; and the barrel diameter of the sampling barrel is smaller than the valve inner diameter of the pneumatic valve. A double-sealing structure is adopted, harmful gas leakage or liquid splashing is avoided, the whole sampling process can be completed only by one operator, and the labor cost is reduced.
