Description

A kind of contactless temperature-measuring mechanism of step-by-step movement push rod furnace
Technical field
The utility model relates to industrial furnace technology field more particularly to a kind of contactless temperature-measuring machines of step-by-step movement push rod furnace Structure.
Background technique
Push rod furnace is one kind of industrial furnace, is mainly used for the heating of the metals embryo such as copper ingot.In process of production, in order to accurate The furnace charge degree of heat in push rod furnace is held, needs to be timed thermometric to furnace charge.Thermocouple, probe etc. is currently mainly used to connect Touch thermometric, since the temperature in push rod furnace is very high, thermocouple and probe are chronically under hot environment, are very easy to damage Bad, worker needs to regularly replace, and thermometric error is also bigger, brings inconvenience to production, also increases production cost, at present It is badly in need of designing a kind of new temperature measuring mechanism, to meet production requirement.
Utility model content
The purpose of the utility model is to overcome the deficiency in above-mentioned background technique, a kind of the non-of step-by-step movement push rod furnace is provided and is connect Touch temperature measuring mechanism, the temperature measuring mechanism have thermometric accurate, and long service life, structure is simple, lower-cost technical characterstic.
The technical purpose of the utility model is achieved in that
A kind of contactless temperature-measuring mechanism of step-by-step movement push rod furnace, it is characterised in that: including be fixed on furnace shell stand, Support, the downwards fixed temperature transducer on the support, the housing being fixed on furnace shell vertically for being fixed on stand top Pipe, insertion housing pipe orifice and upper end are mounted on the inner sleeve in stand by upright guide rail and sliding block, risen above and below driving sliding block The vertical cylinder of drop;The lower end of outer tube overhangs and is inserted into the thermometer hole of roof of the furnace, in the middle part of the upper end of inner sleeve and support The through-hole alignment opened up, temperature transducer, through-hole, inner sleeve, outer tube and thermometer hole are arranged along same vertical axis.
Preferably, the tube wall of the inner sleeve and outer tube is hollow structure, hollow structure is by water inlet and goes out The mouth of a river is connect with cooling water pipeline.
Preferably, the lower end of inner sleeve is stretched out from the lower openings of outer tube when the vertical cylinder declines, passes through and survey Wen Konghou is resisted against on the furnace charge in burner hearth;When vertical cylinder rises, the lower end of inner sleeve is retracted between burner hearth and furnace shell In outer tube.
The utility model has the beneficial effect that the utility model is contactless temperature-measuring, and temperature transducer is in furnace It outside shell, and is abutted directly against on furnace charge when thermometric by inner sleeve, completely cuts off the influence of high-temperature gas in burner hearth, temperature transducer The temperature of furnace charge can be accurately measured, when not needing thermometric, inner sleeve is recoverable to, the traveling and heating of furnace charge are not influenced, Also the high temperature in burner hearth is avoided to damage inner sleeve, overall structure is simple, and easy to use, long working life, cost is relatively low.
Detailed description of the invention
Fig. 1 is the overlooking structure diagram (omitting temperature transducer) of the utility model.
Fig. 2 is the structural schematic diagram of utility model works state.
Fig. 3 is the structural schematic diagram of the utility model off working state.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in further detail.
If Fig. 1 is to a kind of contactless temperature-measuring mechanism of step-by-step movement push rod furnace shown in Fig. 3, including it is fixed on furnace shell 1 Stand 5, be fixed on stand top support 6, fixed (such as the infrared temperature of temperature transducer 9 on the support downwards Sensor), be fixed on outer tube 7 on furnace shell, insertion housing pipe orifice and upper end vertically and pacified by upright guide rail 3 and sliding block 4 The vertical cylinder 2 of inner sleeve 8, driving sliding block oscilaltion in stand.The lower end of outer tube overhangs and is inserted into burner hearth 10 In the thermometer hole at top, the through-hole alignment opened up in the middle part of the upper end of inner sleeve and support is temperature transducer, through-hole, inner sleeve, outer Casing and thermometer hole are arranged along same vertical axis.
The tube wall of the inner sleeve and outer tube is hollow structure, hollow structure by water inlet 12 and water outlet 13 with Cooling water pipeline connection.Inner sleeve and outer tube are cooled down using the cooling water circulated, avoid it in hot environment Lower damage.
When the vertical cylinder declines, the lower end of inner sleeve is stretched out from the lower openings of outer tube, is supported after thermometer hole It leans against on the furnace charge 11 in burner hearth.When vertical cylinder rises, the lower end of inner sleeve is retracted to the outer tube between burner hearth and furnace shell It is interior.
The working principle of the utility model is: erecting as shown in Fig. 2, inner sleeve is in the top position under off working state Straight cylinder is contraction state, and temperature transducer does not work at this time;As shown in figure 3, vertical cylinder ejects downwards under working condition, Sliding block drives inner sleeve decline, and until inner sleeve abuts on furnace charge, temperature transducer starting is measured in inner sleeve inner hole areas Furnace charge surface temperature, the high-temperature gas inside burner hearth has been isolated in inner sleeve at this time, and the temperature measured is closest to the true of furnace charge Temperature, after thermometric, vertical cylinder retraction, inner sleeve resets, and waits thermometric next time.
The above is only the preferred embodiment of the present invention, and for those skilled in the art, this is practical new Type can have various modifications and variations.Within the spirit and principle of the utility model, it is made it is any modification, equally replace It changes, improve, should be included within the scope of protection of this utility model.
