Heating water tank special for water-based spraying workshop in cold region

Abstract

The invention discloses a heating water tank special for a water-based spraying workshop in a cold region. The heating water tank is made of steel plates. The whole heating water tank is located below the water-based spraying workshop, the upper steel plate of the heating water tank is the ground of the water-based spraying workshop, and the lower steel plate of the heating water tank is located on the same horizontal plane of the outer ground of the water-based spraying workshop. A plurality of vertical steel plates which are staggered in parallel are arranged between the upper steel plate and the lower steel plate of the heating water tank and serve as supporting plates. Resistance heating rods which are evenly distributed are arranged on the tank walls on the periphery of the heating water tank. A circular waterway outlet, a circular waterway inlet, a water inlet and a water outlet are formed in the two opposite tank walls connected with the supporting plates, and thermocouples are installed in the heating water tank. The low-temperature hot water in the heating water tank transfers heat in a radiative manner to supply heat to the water-based spraying workshop through the whole ground, the temperature of the workshop is distributed more uniformly and lastingly, the heat supplying efficiency of the workshop is improved, the power consumption is reduced, and normal spraying and film forming of water-based coatings in the workshop in the cold region are ensured.

Description

technical field [0001] The invention belongs to the field of heating equipment for industrial production workshops, in particular to a heating water tank specially used for water-based spraying workshops in cold regions. Background technique [0002] Water-based coatings use water as the dispersion medium, have no organic volatiles, are non-toxic, have no fire hazards, have wide sources, low production costs, can be diluted and cleaned with water, meet the requirements of green production, and have very broad development prospects. [0003] However, it is precisely because water-based coatings use water as the dispersion medium that their application in cold regions is limited. Because the temperature in cold areas is below 0°C for several months, and the humidity is generally low. During this period, although the humidity meets the requirements for spraying and film-forming of water-based paints, water will freeze at temperatures below 0°C, which is not suitable for sprayi...

Problems solved by technology

These two heating methods generally use wall-mounted devices for heat transfer. Although they can meet production requirements, they have their own shortcomings: 1. Large energy consumption; 2. There will be local high and low temperature phenomena, and the temperature distribution in the workshop will be uneven. ;3. Since the hot air rises from the bottom to the top, it is easy to appear the temperature pattern of the workshop where the bottom is cold and the top is hot

However, this heating method is rarely applied to the production workshop, and there is no floor radiation heating system that uses low-temperature hot water as the overall heat medium to transfer heat uniformly and synchronously across the entire area, and is used in the water-based spraying workshop.
