In fig. 1, 1 is a box body with an open top, 2 is an R corner between the bottom surface and the side surface in the box body, 3 is a cover plate, 4 is an R corner between the inner side surface and the side surface of the box body, 5 is an R corner at the upper edge of the inner side surface of the box body, 6 is a feeding overflow port and a plunger valve, 7 is a heating and cooling flow passage, and 8 is a feeding port and a plunger valve.
Detailed Description
For describing the technical solution of the present invention in detail, it is convenient for those skilled in the art to understand the technical principle and technical means adopted by the present invention more accurately, and the technical solution of the present invention will be described in detail below with reference to the form of the embodiment.
Examples
Referring to the attached drawing 1, the utility model discloses a open-top's box, box top set up the clamp plate the same with box top size, and the clamp plate is made by the light steel sheet that thickness is 1.5 mm. The pressing plate is opposite to the top of the box body and can be pressed on the box body to form a sealing structure with the box body. The bottom plate of the box body 1 is provided with a jacket flow channel 7 for automatic heating and cooling, a heating medium is heated by steam or heat conducting oil, and a cooling medium is cooled by circulating water. The side of box sets up reinforced import 8 and 2 overflow gas vents 6, and reinforced import 8 sets up the plunger valve, sets up the connecting pipe on the plunger valve, and overflow gas vent 6 sets up on two relative box curb plates with reinforced import 8. The bottom surface and the side surface of the inner wall of the box body are provided with an R angle 2 transition with the size of 10% of the depth of the mould, an R angle 4 transition with the size of 15% of the depth of the mould is arranged between the side surface and the side surface, and an R angle 5 transition with the size of 5% of the depth of the mould is arranged on the upper corner of the side surface of the box body.
