Put.
Background technology
Blast furnace blower is the important component of blast furnace production.Winter, blast furnace stop production to overhaul（Time, length was more than 12
Hour）Afterwards, when blast furnace need to resume production, air blower need to normally be run, but be due to air blower its lubrication after shutting down 12 hours
Lubricating Oil Temperature in fuel tank, which can be reduced to, to be opened below machine temperature, it is impossible to is met air blower and is opened confidential ask（Lubricating Oil Temperature oil temperature
More than 30 DEG C）, therefore start before air blower, it is necessary to the Lubricating Oil Temperature in first its grease-box is heated to opening machine temperature.Mesh
Preceding used Lubricating oil heating device heats for thermojunction type.This thermojunction type heater has the following disadvantages：（1）Plus
Thermal velocity is slow, it is necessary to which the lubricating oil in grease-box could be heated to opening machine temperature for 6 hours by heating；（2）Thermocouple adds for electricity
Heat, energy consumption is big；（3）After thermocouple break, fluid can be not only polluted, and repair extremely inconvenient, it is necessary to first by grease-box
Interior lubricating oil could be repaired after extracting out.
The content of the invention
It is an object of the invention to provide a kind of firing rate is fast, energy-conservation and a kind of blast furnace blower profit easy to maintenance
Lubricating oil heater.
To achieve the above object, present invention employs following technical scheme：A kind of described blast furnace blower lubricating oil adds
Thermal, including the snakelike heat exchange tube being laid on grease-box outer wall, the water inlet of snakelike heat exchange tube by jet chimney with
Steam source is connected, and the delivery port of snakelike heat exchange tube connects the outlet conduit in ditch, is provided with outlet conduit thin
Water valve, is also parallel with bypass pipe on outlet conduit, and the water inlet end of bypass pipe is connected with the outlet conduit of drain valve influent side,
The water side of bypass pipe is connected with the outlet conduit of drain valve water outlet side, and ball valve is provided with bypass pipe.
Further, foregoing a kind of blast furnace blower Lubricating oil heating device, wherein：The structure of snakelike heat exchange tube is：
Including some parallel straight tubes being laid in side by side on grease-box outer wall, adjacent two straight tubes are joined end to end two-by-two by bend pipe
Connect.
Further, foregoing a kind of blast furnace blower Lubricating oil heating device, wherein：Is provided with jet chimney
One stop valve.
Further, foregoing a kind of blast furnace blower Lubricating oil heating device, wherein：It is additionally provided with jet chimney
Second stop valve.
Further, foregoing a kind of blast furnace blower Lubricating oil heating device, wherein：Tune is provided with jet chimney
Save valve.
By the implementation of above-mentioned technical proposal, the beneficial effects of the invention are as follows：（1）Firing rate is fast, only needs 1~2 hour
Lubricating Oil Temperature can be just heated to opening machine temperature；（2）Electric energy, more energy efficient environmental protection can be instead of using steam；（3）Due to all
Conduit connection point be respectively positioned on outside grease-box, staff can just be repaired outside grease-box during maintenance, be tieed up
Repair easy to operate.
Brief description of the drawings
Fig. 1 is a kind of structural representation of blast furnace blower Lubricating oil heating device of the present invention.
Fig. 2 is the A direction views of grease-box in Fig. 1.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of described blast furnace blower Lubricating oil heating device, including the grease-box 1 that is laid in
Snakelike heat exchange tube 2 on outer wall, the water inlet of snakelike heat exchange tube 2 is connected by jet chimney 3 with steam source 4, snakelike to change
The delivery port of heat pipe 2 connects the outlet conduit 6 in ditch 5, and drain valve 7 is provided with outlet conduit 6, in outlet conduit 6
On be also parallel with bypass pipe 8, the water inlet end of bypass pipe 8 is connected with the outlet conduit 6 of the influent side of drain valve 7, and bypass pipe 8 goes out
Water end (W.E.) is connected with the outlet conduit 6 of the water outlet side of drain valve 7, and ball valve 9 is provided with bypass pipe 8；In the present embodiment, it is snakelike
The structure of heat exchanger tube 2 is：Including some parallel straight tubes being laid in side by side on the outer wall of grease-box 1, adjacent two straight tubes lead to
Cross bend pipe and join end to end two-by-two and connect, the snakelike heat exchange tube of said structure it is simple in construction, it is convenient to install and maintain；In the present embodiment
In, the first stop valve 10 is provided with jet chimney 3, so when seepage occurs in each pipe joint, stop valve 9 can be passed through
Steam off pipeline 2, carries out maintenance of stopping the supple of gas or steam；In the present embodiment, the second stop valve 11 is additionally provided with jet chimney 3, this
Sample, can be by the steam off pipeline 3 of the second stop valve 11 when the first stop valve 10 breaks down, or works as the second stop valve
