Moveable-type accurately-controllable-temperature full-plastic storage tank rotational moulding device

Abstract

The invention discloses a movable-type accurately-controllable-temperature full-plastic storage tank rotational moulding device which comprises shells, heat insulation layers, electric heating screens, heat conducting layers, molds body and the like. The electric heating screens are used for heating up the device; the heat insulation materials are used for covering the outer layers of the electric heating screens; high-heat-conducting materials are used for covering the outer layers of the molds; the electric heating screens comprise six modules along the circumferential directions of the molds, and an independent power supply mode is adopted, and the power supply sequence and the power supply current are controlled by a power distribution system; the device adopts a closed-loop control system to control the temperature accurately; and snake-shaped channels are processed on the heat insulation layers outside the electric heating screens, and the molds can be cooled down rapidly. The movable-type accurately-controllable-temperature full-plastic storage tank rotational moulding device provided by the invention has the advantages of accurate temperature control, uniform temperature, convenience and quickness in moving, convenience in cooling, energy source conservation and the reduction of storage tank rotational moulding processing cost.

Description

technical field [0001] The invention discloses a rotomolding equipment, in particular a rotomolding device utilizing electric heating, in particular a movable precise and controllable temperature rotomolding device for an all-plastic storage tank. Background technique [0002] Rotational molding is a method of hollow molding thermoplastics. Due to the advantages of many varieties, low density, high specific strength, chemical corrosion resistance and excellent formability, plastic products have been widely used in the industrial field, and large storage tanks are one of the most widely used products. However, the rotomolding storage tank process is restricted by the energy used for molding, and the mobility of the device is poor; and the temperature in the rotomolding process is not easy to control, resulting in uneven wall thickness of the storage tank. These process defects have greatly hindered the application and development of rotational molding storage tank technology...
