[0037] AsFigures 1-2 As shown, the present application provides a neoprene drying device, which comprises a pretreatment unit and a drying oven 1 arranged in sequence; the pretreatment unit is used for primary dehydration of the rubber film, and the drying oven 1 is used for heating and drying treatment of the neoprene rubber film after the pretreatment unit treatment; the drying oven 1 can be any existing drying oven 1 device, wherein one embodiment of the drying oven 1 comprises a drying conveying mechanism 2 for conveying the rubber film, and a plurality of oven covers 3 arranged above the drying conveying mechanism 2; the drying conveying mechanism 2 can be any existing rubber film conveying device, and one embodiment is a fourdrinier machine, which is a planar linear structure. Figure 3 As shown, the second embodiment of the drying conveying mechanism 2 is composed of a chain, a support rod, a shaft, a sprocket, a bearing, and a power driving device in the drying box; the running speed of the drying conveying mechanism 2 must ensure that the neoprene rubber film is conveyed flatly and cannot be stranded; if the running speed of the drying conveying mechanism 2 is slow, the rubber film cannot be stretched, and the rubber belt is prone to be transversely folded; if the speed is too fast, the rubber belt is excessively stretched and is prone to be folded in the longitudinal direction, which will affect the normal drying of the rubber belt; in the present application, five oven covers 3 are taken as an example, the upper sides of the first four oven covers 3 are connected with a heater 5 through an air outlet pipe 4 (the last oven cover 3 is not connected with the heater 5), the heater 5 is connected with a steam pipe 7 through a shunt pipe 6, the steam pipe 7 is provided with a steam main pipe 8, which is used for being connected with a steam source in the factory area, the shunt pipe 6 is respectively provided with a one-way valve 9, which is conducted from the steam pipe 7 side to the heating pipe side; the lower side of the drying conveying mechanism 2 is provided with a corresponding liquid collecting hopper 10 of the oven cover 3, the liquid collecting hopper 10 is a conical structure, and a total of five liquid collecting hoppers 10 are arranged; the bottoms of the five liquid collecting hoppers 10 are connected with a gas-liquid separator 12 through a separator inlet pipe 11, the exhaust sides of the first three gas-liquid separators 12 are connected with the heater 5 on the next oven cover 3 through a separator outlet pipe 13, the exhaust side of the fourth gas-liquid separator 12 is communicated with the upper side of the fifth oven cover 3 through the separator outlet pipe 13, and the exhaust side of the fifth gas-liquid separator 12 is connected with the first heater 5 through the separator outlet pipe 13; the five separator outlet pipes 13 are respectively provided with a fan 14; the liquid discharge ends of the five gas-liquid separators 12 are connected with a liquid discharge main pipe 15; and the last separator outlet pipe 13 is connected with a pressure relief valve.

[0038] When the rubber film of chlorobutyl rubber is dried, the pretreatment unit dehydrates the rubber film once; the drying oven transmits heat to the wet rubber film through hot air, the water on the surface of the wet rubber film vaporizes and diffuses into the hot air through the surface air film; at the same time, due to the vaporization of the water on the surface of the material, a humidity difference is caused between the inside and the surface of the rubber film, so the water in the inside of the material diffuses to the surface in the form of gas or liquid, and finally enters the hot air in the form of gas; specifically, the steam source in the factory enters the inside of the steam pipe 7 through the steam main pipe 8, and supplements steam to the inside of the heater 5 and the oven cover 3 through the shunt pipe 6; the fan 14 is started, the steam temperature in the inside of the first oven cover 3 is 120℃, after the rubber film of chlorobutyl rubber is dried, it enters the first liquid collecting tank 10 and is separated through the gas-liquid separator 12, the water in the gas enters the liquid discharge main pipe 15 through the liquid discharge end of the gas-liquid separator 12; the gas after gas-liquid separation enters the heater 5 through the separator outlet pipe 13 to be further heated, and then enters the inside of the next oven cover 3; the temperatures in the inside of the five oven covers 3 are 120℃, 130℃, 140℃, 135℃ and 120℃ respectively; the gas separated by the last gas-liquid separator 12 enters the first heater 5 through the separator outlet pipe 13 for recycling; the rubber film of chlorobutyl rubber is directly blown by the oven cover 3, so that the rubber film of chlorobutyl rubber is tightly attached to the dry conveying mechanism 2 and is conveyed.

[0039] The pretreatment unit is used for one-time dehydration of the rubber film, such as Figures 4-5As shown, the pretreatment unit includes a pretreatment frame 16 and a dewatering mechanism mounted on the pretreatment frame 16.
