Electric heating knife rest for butting tetrafluorohydrazine cylinder

Abstract

The invention discloses an electric heating knife rest for butting a tetrafluorohydrazine cylinder. The electric heating knife rest comprises a side fixing frame; a lower bracket is hinged to the sidefixing frame; one side, close to the side fixing frame, of the lower end of the lower bracket is provided with a jacking device, and the other side is provided with supporting legs; the upper end face of the lower bracket is provided with a lower heating box; the two sides of the upper end of the lower heating box are each provided with an inclined side supporting plate; the upper end face of thelower bracket is provided with a fixing seat; the fixing seat is provided with a screw rod I; the screw rod I is sequentially sleeved with a nut I, a side bracket and a pressing bar from top to bottom; the lower end of the side bracket is provided with a plurality of pressing blocks II; a heating tube I is arranged inside the lower heating box; a lower heating plate is arranged at the upper end of the lower heating box; an upper bracket is arranged above the lower bracket; the lower end of the upper bracket is provided with a plurality of pressing blocks I; an upper heating box is arranged atthe lower ends of the pressing blocks I; a heating tube II is arranged inside the upper heating box; and the lower end of the upper heating box is provided with an upper heating plate. The contact area of a joint of the tetrafluorohydrazine cylinder butted by using the electric heating knife rest disclosed by the invention is large, the firmness is higher, a pressed surface is uniform in thickness and high in quality, and the molded tetrafluorohydrazine cylinder is higher in durability.

Description

technical field [0001] The invention relates to the field of polytetrafluoroethylene, in particular to an electric heating knife holder for butt jointing of tetrafluoro cylinders. Background technique [0002] Tetrafluoroethylene is a polymer of tetrafluoroethylene, abbreviated as PTFE. Polytetrafluoroethylene is hardly corroded by any chemical reagents. For example, it is boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid, or even in aqua regia, and its weight and performance have no change. It is also almost insoluble in all solvents, and only slightly soluble in alkanes above 300°C. Polytetrafluoroethylene does not absorb moisture, is non-flammable, and is extremely stable to oxygen and ultraviolet rays. All of them have excellent weather resistance. Except for alkali metals, it is hardly overlooked by any chemical reagents. It is widely used as high and low temperature resistant, corrosion resistant materials and insulating materials in industries such ...

Problems solved by technology

[0003] In some transportation pipelines, transportation tanks or storage tanks, the main part of the inner wall of the PTFE protective layer is the PTFE cylinder rolled from PTFE sheet, and the PTFE sheet must be processed into the PTFE cylinder. The two ends need to be butted, and the quality of the connection is the main factor affecting the quality of the PTFE cylinder. The conventional operation method is to bend the two ends of the PTFE plate, and melt the PTFE welding rod to the seam to complete th
