Problems solved by technology

Although the local cooling device has the characteristics of improving the local cooling effect and reducing the ineffective cooling section, it has the disadvantages that the release device is not universal, the salt water corrodes the cooling pipeline greatly, and the cooling capacity of the compressed air is small. Sensible heat storage, cold storage is small

Embodiment Construction

[0017] It can be seen from the accompanying drawings that a cooling device is used for cooling in a local working site of a mine or in an underground facility or in a tunnel construction site. The cooling device includes a storage tank 1 and a water storage tank 2 arranged on a mobile vehicle body 18, and they communicate with the air cooler 10 through a medium circulation pipe 20 to form a cooling circulation loop. The air cooler 10 can be integrated with the water storage tank 2 or can be separately installed in the work site.

[0018] This embodiment is mainly used for synchronous mobile cooling at the mining site of the mine. In order to reduce production costs, provide flexible cooling and overcome the difficulty of underground condensation heat discharge, the mobile car body 18 selects the existing mine car chassis in the mine, and the storage box 1 and the water storage tank 2 are fixed on the mine car chassis. Auxiliary cooling facility assembly process, streamlining ...

Abstract

This invention relates to a mining local cool supply device, which comprises an ice storage tank and a water storage tank in the mobile vehicle, interconnected with air cooler through agent circulating pipe, wherein the agent circulating pipe is multilayer dish type heat-exchanger rig when it passes the ice storage tank, and connected with the bore-hole pump when it passes the water storage tank. By said technique, the cool supply device below the well can discharge condensation heat, and the pump does not need to do explosion-proof process; besides, the system does not need to process corrosion prevention. The invention is fit for supplying cool in mining, underground installation and tunneling operation place.

Description

technical field [0001] The invention relates to a cooling device, in particular to a local cooling device for mines, underground facilities or tunnels. Background technique [0002] Mine artificial cooling systems mainly include ground centralized, underground centralized, underground mobile and underground local cooling systems. The centralized cooling system on the ground of the mine is composed of chillers, chilled water pumps, air coolers, cooling water pumps, and cooling towers; on the one hand, due to the high hydrostatic pressure of the chilled water system, high and low pressure conversion equipment must be equipped, and chilled water is in the high and low pressure conversion equipment. During the conversion, there will be a temperature jump, which increases the temperature of the chilled water; on the other hand, the chilled water has a long transportation distance, and the cooling loss along the way is large, and the temperature of the chilled water is further inc...
