Description
Technical Field
The utility model relates to a chemical industry equipment, in particular to tetrafluoro inside lining laminating compaction device.
Background
The conveying of corrosive slurry in chemical industry, non-ferrous metal hydrometallurgy, mine beneficiation and chemical fertilizer industry needs to use an anti-corrosion pipe wear-resistant pump valve, and the slurry conveyed in the industries contains strong corrosive media such as fluorine, sulfuric acid, hydrochloric acid and the like, so that the conveying pump valve has high anti-corrosion requirements, and the slurry contains a large amount of solid, so that the wear resistance requirements of the pump valve are also high.
Tetrafluoro is a polymer of tetrafluoroethylene. Abbreviated english as PTFE. Polytetrafluoroethylene (tetrafluoro) is hardly corroded by any chemical agent. For example, when boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid, or aqua regia, the weight and properties of the product are unchanged, and the product is almost insoluble in all solvents and slightly soluble in whole paraffin (about 0.1g/100 g) at temperatures above 300 ℃. The polytetrafluoroethylene is not hygroscopic and inflammable, and is stable to oxygen and ultraviolet rays, so that the polytetrafluoroethylene has excellent weather resistance. Because of the advantages, the main method at present is to attach the polytetrafluoroethylene lining to the inner wall of the pump valve. In the existing lamination process of the polytetrafluoroethylene lining, an arc plate fitted with the inner wall of the polytetrafluoroethylene lining is continuously and manually pressed, and finally the polytetrafluoroethylene lining is laminated on the inner wall of a pipeline of a pump valve; however, this method has the disadvantages of low efficiency, high labor intensity and non-uniform bonding.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tetrafluoro inside lining laminating compaction device. The utility model has the characteristics of efficient, low in labor strength and laminating are even.
The technical scheme of the utility model: a polytetrafluoroethylene lining laminating and compacting device comprises a vehicle platform, wherein a vehicle rail is laid on the vehicle platform, a self-propelled trolley is arranged on the vehicle rail, a motor is arranged on the self-propelled trolley, the motor is connected with a main shaft through a coupler, and the main shaft is in sliding connection with a sliding sleeve through a key connection structure; the sliding sleeve is connected with a telescopic driving assembly which drives the sliding sleeve to slide along the axial direction of the spindle, a connecting rod is hinged on the periphery of the sliding sleeve, the connecting rod is hinged with a sliding block, the sliding block is connected with a guide rail in a sliding manner, the guide rail is connected with a supporting disk, and the supporting disk is connected with the end part of the spindle; the sliding block is also provided with a support, the support is connected with the arc plate, the circle center of the arc plate is superposed with the axis of the main shaft, and the cambered surface of the arc plate is also distributed with self-rotating compression rollers.
In the tetrafluoro lining attaching and compacting device, the main shaft is supported by a bearing seat arranged on the self-propelled trolley.
In the tetrafluoro liner laminating and compacting device, the telescopic driving component is one of an electric push rod, an air cylinder or a hydraulic cylinder.
Compared with the prior art, when the polytetrafluoroethylene lining is attached, the pump valve pipeline is fixed through the fixing seat and is coaxial with the main shaft, the self-propelled trolley moves to stretch the arc plate into the pump valve pipeline, then the telescopic driving assembly extends to stretch the arc plate, so that the arc plate is stretched, the compression roller is pressed on the polytetrafluoroethylene lining, the motor is started to rotate the arc plate, the compression roller on the arc plate rotates along with the arc plate and generates autorotation, and the polytetrafluoroethylene lining is further compressed to be closely attached to the inner wall of the pump valve pipeline; after compaction, the telescopic driving assembly contracts to contract the arc plate, so that the compression roller is separated from the tetrafluoro liner, and the self-propelled trolley moves forwards for a compaction stroke at the moment and continues to compact until the whole tetrafluoro liner is compacted on the inner wall of the pump valve pipeline; through this structure, replaced manual operation, improved efficiency, reduced intensity of labour, made the laminating more even.
To sum up, the utility model has the characteristics of efficient, low in labor strength and laminating are even.
