Description

Technical Field

[0001] This utility model relates to the field of water supply system technology, specifically to a fog cannon intelligent water supply system. Background Technology

[0002] According to the requirements of the National Opinions on Promoting the Implementation of Ultra-Low Emissions in the Steel Industry (Environmental Protection and Control

[2019] No. 35), existing industrial enterprises are required to install fixed mist cannons, fixed fog sprayers, and other related dust suppression facilities in areas where raw materials, coal yards, and coke are stored. Currently, most of these raw material storage areas in northern regions lack indoor heating facilities. Therefore, the conventional practice for supplying water to mist cannons is to install electric heating cables on the water supply pipelines for winter insulation. This practice has the following problems:

[0003] 1. The electric heating tape has a power of 380V / 220V. In the event of leakage, there is a risk of electric shock on site.

[0004] 2. The actual performance of electric heating tape is generally poor. After 2-3 years of use, it will stop heating and need to be replaced regularly, which increases operating costs.

[0005] 3. The large number of fog cannons in large storage yards puts a heavy burden on on-site staff, requires extensive equipment maintenance, and is prone to management errors, failing to meet national requirements for intelligent and green industrial projects. Utility Model Content

[0010] A water supply pipe connected to the water inlet of the fog cannon; the water supply pipe is used to supply water to the fog cannon.

[0011] A drain pipe, connected to the water supply pipe, is used to drain the water from the pipe after the water supply has stopped.

[0012] Preferred technical solution 1: The water supply pipe includes a main water supply pipe and a branch pipe, and the main water supply pipe is connected to the water inlet of the mist cannon through the branch pipe;

[0013] The drain pipe is fixedly connected to the main and branch water supply pipes.

[0016] Preferred technical solution four: The switching valve one and switching valve two are connected to an external control box or remote control from the central control room.

[0017] (III) Technical Effects

[0018] The above structure gives this solution the following advantages:

[0019] 1. Eliminate the use of heating cables to remove safety hazards to on-site workers caused by them;

[0020] 2. By adding a drain pipe and a switch valve to the water supply pipeline, the residual water can be drained in time after the fog cannon is stopped, thus avoiding damage from freezing.

[0021] 3. By connecting the switching valve to a local control box or central control room for remote control, complete automation can be achieved, improving the work efficiency of operators and realizing the intelligent and green transformation of the factory. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-2The intelligent water supply system of the fog cannon 2 includes a water supply pipe 1 connected to the water inlet of the fog cannon 2, which is used to supply water to the fog cannon 2; and a drain pipe 3 connected to the water supply pipe 1, which is used to drain the water between the connection between the drain pipe 3 and the water supply pipe 1 and the water inlet of the fog cannon 2 after the water supply pipe 1 stops supplying water.

[0029] Specifically: the water supply pipe 1 includes a main water supply pipe 11 and a branch pipe 12. One end of the main water supply pipe 11 is connected to a water supply device, which supplies water to the main water supply pipe 11. The other end is connected to the inlet of the mist cannon 2 through the branch pipe 12. At the same time, the drain pipe 3 is fixedly connected to the connection between the main water supply pipe 11 and the branch pipe 12. A switch valve 1 4 is installed on the main water supply pipe 11, and a switch valve 2 5 is installed on the drain pipe 3.

[0030] When fog cannon 2 is in normal operation: switch valve 25 is closed and switch valve 14 is open, so that fog cannon 2 can supply water normally.

[0031] When the fog cannon 2 is stopped: first close switch valve 1 4, then open switch valve 2 5, delay for a period of time (e.g., 2 minutes) to drain the residual water in branch pipe 12, then close switch valve 2 5, thereby canceling the installation of the electric heat tracing cable of the original water supply pipe 1.

[0032] Example 2

[0033] Based on Example 1

[0034] Please see Figures 1-2 The fog cannon 2 intelligent water supply system uses electric valves 4 and 5, which are connected to an external control box (using existing technology) or a central control room (using existing technology) for remote control, enabling the fog cannon 2 to operate fully automatically.

[0035] The control box or central control room is used to remotely control the opening and closing of switch valve 4 and switch valve 5, that is:

[0036] When fog cannon 2 is in normal operation: control valve 2 5 is closed and switch valve 1 4 is open to achieve normal water supply for fog cannon 2;

[0037] When the fog cannon 2 is stopped: first control the shut-off valve 4, then open the valve 5. After the residual water in the branch pipe 12 is drained, close the valve 5.

[0038] Example 3

[0039] Based on Example 1 or 2

[0040] Please see Figures 1-2 The Fog Cannon 2 intelligent water supply system also includes a valve well to protect the main water supply pipe 11 from freezing and preventing it from frost heave below the frost line.
