Hot rubber sheet rapid cooling system

Abstract

The invention discloses a system for quickly cooling hot rubber sheets. The system comprises a rack, a conveying device, an atomizing device, an isolation hood, an air exhausting device and a control part, wherein the conveying device is used for conveying the hot rubber sheets; the isolation hood is used for isolating the conveying device and the atomizing device from the ambient atmosphere; the atomizing device comprises one or more atomizing pipelines and nozzles which are formed in the atomizing pipelines; the isolation hood is fixedly connected to the rack; an opening is formed in the isolation hood; the conveyed hot rubber sheets pass through the opening; the air exhausting device is fixedly connected to the upside of the isolation hood; a liquid collecting plate and a liquid discharging pipe are arranged at the lower part of the rack; the liquid discharging pipe is connected to the bottom of the liquid collecting plate; the control part at least comprises a linked operation controller, an atomizing pressure flow controller and an emergent controller. The system is capable of shortening the cooling length of hot material products, reducing the equipment investment, reducing the production site occupancy, reducing the consumption of power and water and also reducing the production of waste gas and waste water and is suitable for products needing to be cooled in manufacturing and processing lines of rubber, plastic, metal, glass or other materials.

Description

technical field [0001] The invention relates to rubber processing, in particular to a rapid cooling system for hot rubber sheets during rubber processing. Background technique [0002] In the process of rubber processing, it is necessary to heat the mixed rubber to above 100°C and up to 170°C, and then form hot rubber sheets, semi-finished products or products of various shapes through extrusion, calendering and other processes. At present, the cooling methods of hot rubber products mainly include: natural air cooling, water spray + immersion + blowing, air-conditioning air cooling, circulating water cooling metal rollers, etc. [0003] The cooling methods mentioned above take away the heat on the hot rubber sheet through the sensible heat change (temperature rise) of the medium (water or air). Relatively speaking, the cooling efficiency is very low, especially in the hot summer (the ambient temperature reaches 35 ℃), the flow rate of the cooling medium (wind, water, etc.) ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, there are the following disadvantages in water tank immersion cooling: the cooling mainly depends on the temperature change of the medium water to take away the heat, which is to use the sensible heat of the medium to cool down. The specific heat capacity of water is only 4.2kJ / kg.℃, so the cooling speed is slow and the water demand is large. Disadvantages such as large power consumption, large amount of regular water treatment, large plant area, etc.
