[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.

Embodiment 1
[0037] see figure 1 , figure 2 , image 3 .
[0038] This hot rubber rapid cooling system includes a frame 1, a conveying device 2 for conveying hot rubber sheets, a spray device 3, an isolation cover 4 for separating the conveying device 2 and spray device 3 from the ambient atmosphere, and an exhaust device 5 and control section 6,
[0039] The spraying device 3 includes more than one independent spraying pipeline and nozzles arranged on the spraying pipeline, and the spraying pipeline has an upper spraying pipeline 7 and a lower spraying pipeline 8 .
[0040] The isolation cover 4 is fixedly connected with the frame 1 and has an opening through which the hot rubber sheet for conveying passes.
[0041] The exhaust device 5 is fixedly connected above the isolation cover 4,
[0042] A liquid collection tray 16 and a drain pipe 17 connected to the bottom of the liquid collection tray 16 are arranged at the bottom of the frame 1. The collection tray 16 is made of metal mat...
Embodiment 2
[0060] see figure 1 , figure 2 , Figure 4 .
[0061] The present embodiment is the same as the embodiment 1 except that the spraying device is different from the embodiment 1. In this embodiment, the nozzle of the spraying device 3 is sprayed with a liquid pressurized single-fluid nozzle 21, and the high-pressure water is used to pass through the flow obstacle to change the hydrodynamic properties of the aerosol flow discharged from the spray head, so that the water is atomized into small Single-fluid nozzle for water droplets. The pressure of the high-pressure water is 3-20 MPa, preferably 4-15 MPa.
[0062] This spraying device 3 comprises water tank 18, booster pump 19, control valve 14, high-pressure delivery pipe 20, nozzle 21; The operating system 6 is respectively connected to a booster pump 19 and a control valve 14 .
[0063] The control valve 14 is a solenoid valve.
[0064] The spraying device 3 also includes a liquid filter 13 , and the liquid filter 13 is...
Embodiment 3
[0071] This embodiment is similar to Embodiment 1, except that the liquid supply of the two-fluid nozzle is a siphon type that uses compressed air force to suck the liquid onto the spray, and the water source is the clean water in the water tank.

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.) ...
