Abstract
The utility model relates to a cooling water leakage and blockage detecting device of a heating furnace. The cooling water leakage and blockage detecting device comprises a cooling water inlet main pipe and cooling water branch pipes of the heating furnace, wherein a pressure detecting device and a temperature detecting device are arranged on the cooling water inlet main pipe of the heating furnace; the temperature detecting device is respectively arranged on an outlet of each cooling water branch pipe; and whether a phenomenon of leakage or blockage exists in cooling pipes of the heating furnace or not is judged through monitoring and comparing temperatures of the cooling water inlet main pipe of the heating furnace and the cooling water outlet branch pipes of the heating furnace as well as the temperatures of the cooling water inlet main pipe of the heating furnace and cooling water outlet branch pipes of the heating furnace by utilizing temperature signals and beng in assist of monitoring the pressure of the cooling water inlet main pipe of the heating furnace. By adopting the technical scheme, the device is easy to implement, strong in reliability and low in investment cost.
Description
Technical field
The utility model relates to the rays safety detection apparatus of helping that attaches of heating furnace in the metallurgy industry, particularly relates to a kind of cooling water pipe leak detection and inspection block apparatus of heating furnace.
Background technology
In the walking beam furnace of prior art; The step rate of inside heating furnace and built-in beam all need cooling; And need keep watch on the cooling water of every step rate or built-in beam constantly; Take place to leak or stop up with the cooling water of avoiding taking place certain root step rate or built-in beam, thereby cause the temperature of beam too high, make the beam body deformability even the damage of step rate and built-in beam.
In the prior art the cooling water of step rate and built-in beam being kept watch on common practices is that coolant outlet arm at heating furnace is provided with flow switch or flowmeter; Judge through the variation of keeping watch on cooling water arm discharge whether the cooling arm exists the situation of revealing or stopping up; Though this mode also can realize hunting leak and examining stifled function, the price of flow switch or flowmeter is a price that temperature element is nearly 10 times, and the discharge of the coolant outlet arm of heating furnace changes and finally can be embodied on the temperature of exit branch water; There is situation about revealing when certain cooling water arm; Then because the water yield of this arm process heating furnace reduces, the temperature of its water outlet can be higher with respect to other arm, and is higher than inlet house steward's temperature; And the pressure on the house steward of cooling water inlet also has the trend that reduces; Stop up if work as certain arm, then the cooling water of this arm is long in the time that the heating furnace the inside stops, and the temperature of its water outlet can be higher with respect to other arm; Temperature than the inlet house steward is higher; And the pressure on the house steward of cooling water inlet also has the trend of increase, thus can judge the changes in flow rate of outlet stool through detecting the outlet stool variation of temperature, and then judge certain arm and whether have the situation of revealing or stopping up to exist.
Summary of the invention
In view of this, the main purpose of the utility model is to provide a kind of cooling water pipe leak detection and inspection block apparatus of heating furnace, through the present technique scheme, and not only easy to implement, good reliability, and cost of investment is low.
In order to achieve the above object; The technical scheme of the utility model is achieved in that a kind of cooling water leak detection and inspection block apparatus of heating furnace; Include the cooling water inlet house steward and the cooling water arm of heating furnace; The cooling water inlet house steward of said heating furnace is provided with pressure-detecting device and temperature-detecting device, in the outlet of each cooling water arm, temperature-detecting device is set.
The cooling water inlet house steward of said heating furnace is provided with flow detector.
Beneficial effect after the employing technique scheme is: a kind of cooling water leak detection of heating furnace and inspection block apparatus; Relatively the temperature between the coolant outlet arm of temperature, the heating furnace of the cooling water inlet house steward's of heating furnace temperature and the coolant outlet arm of heating furnace and the total pipe pressure in cooling water inlet that is aided with heating furnace are judged whether the cooling tube of heating furnace exists and are revealed perhaps phenomenon of blocking through temperature signal monitoring; Adopt the present technique scheme; Not only easy to implement, good reliability, and cost of investment is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 heating furnace, 2 cooling water inlet house stewards, 3 cooling water arms, 4 flow detectors, 5 pressure-detecting devices, 6 temperature-detecting devices.
The specific embodiment
Be described further below in conjunction with specific embodiment and accompanying drawing technical scheme the utility model.
As shown in Figure 1; The cooling water leak detection of the heating furnace that the utility model relates to and inspection block apparatus; Include the cooling water inlet house steward 2 and cooling water arm 3 of heating furnace 1; The cooling water inlet house steward 2 of said heating furnace 1 is provided with pressure-detecting device 5 and temperature-detecting device 6, and temperature-detecting device 6 is set in the outlet of each cooling water arm 3.
The cooling water inlet house steward 2 of said heating furnace 1 is provided with flow detector 4.
In the specific embodiment of the utility model; Temperature-detecting device 6 selects then thermal resistance as temperature element, and calibration number is PT1000, and is installed in respectively on the cooling water inlet house steward 2 of heating furnace 1; The coolant outlet arm 3 of heating furnace 1, mounting means are plug-in type; Device for pressure measurement 5 is selected pressure transmitter for use; Pressure signal and temperature signal are sent in the signal monitoring system through Shielded Twisted Pair; The signal monitoring system selects PLC for use; In the temperature signal monitoring system; Temperature between the coolant outlet arm 3 of the temperature through the cooling water inlet house steward 2 of heating furnace 1 relatively and the temperature of the coolant outlet arm 3 of heating furnace 1, heating furnace 1 and cooling water inlet house steward 2 pressure that are aided with heating furnace 1 are judged whether the cooling water arm 3 of heating furnace 1 exists and are revealed or phenomenon of blocking exists, and control system through PLC at last and leak to certain cooling water arm 3 of operating personnel's alarm, perhaps blockage phenomenon.
The above is merely the preferable possible embodiments of the utility model, is not in order to limit the protection domain of the utility model.
Claims (2)
