Abstract
The utility model discloses a movable fixing device to be matched with a recirculation zone measuring device to be used and relates to a movable measuring fixing device for a recirculation zone. The movable measuring fixing device comprises a sliding bar with a sliding groove, supports and a measuring bar. The supports are arranged at two ends of the sliding bar, the measuring bar is embedded in the sliding groove of the sliding bar through a connector and capable of moving along the sliding groove. Parts of the device are connected through bolts, so that the dismounting is facilitated, and test time and a large amount of labor can be saved during utilization; and as the number of testers in a hearth is reduced, the security risk is reduced, and the test accuracy during testing through the device is improved.
Description
Technical field
The utility model relates to a kind of removable recirculating zone and measures stationary installation.
Background technology
At present, the widely used a kind of combustion system of large-sized station boiler is the opposed firing burning, its major equipment turbulent burner is the rotation that utilizes Secondary Air, produce the recirculating zone, entrainment high-temperature flue gas, add the heat primary air breeze airflow to the ignition temperature of coal dust, reach the purpose of smooth combustion, therefore, the size of the scope of recirculating zone and swirl strength has a great impact combustion position.
Prior art is generally by recirculating zone scope and swirl strength size in cold air dynamic field experimental measurement Pulverized Coal fired Boiler Furnace, when measuring the recirculating zone, needs at least the 3 hand-held measurement mechanisms of people, makes measurement mechanism be fixed on the center of burner.Because the burner hearth intraoral illumination is poor, wind speed is high, and is operated on framing scaffold more than 5 meters work under bad environment, therefore increasing testing crew also can bring huge potential safety hazard, and manually set up measurement mechanism and also need test period, bring error to experimental measurement simultaneously, therefore at present in the urgent need to a kind of stationary installation that can move at any time, reduce the number of testing crew in burner hearth, shorten test period in burner hearth, reduce security risk, improve test accuracy.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of stationary installation that can coordinate the recirculating zone measurement mechanism to use in the station boiler cool power field test of opposed firing burning.
The technical solution of the utility model is as follows:
The utility model comprises slide bar with chute, be arranged on the support at slide bar two ends and by the connector embedding in the chute of slide bar and the sounding rod that can move along chute.
Support described in the utility model is expansion link.
Be provided with scale on slide bar described in the utility model, be provided with on described sounding rod for the distance scale of measuring test unit and slide bar.
Good effect of the present utility model is as follows: the utility model is as a kind of stationary installation that movably coordinates the recirculating zone measurement mechanism to use, equipment is simple, for convenience detach, and with low cost, adopt the utility model can save test period and a large amount of manpowers, can be applicable to Capital Construction Debugging and the pilot production aspect of large-sized station boiler.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
In the accompanying drawings: 1 support, 2 slide bars, 3 sounding rods, 4 chutes, 5 connectors.
Embodiment
As shown in Figure 1, the utility model comprises support 1, slide bar 2 and sounding rod 3, and described support 1 can move up and down for expansion link, and support 1 is arranged on the two ends of slide bar 2, be used for fixed slip bar at burner central shaft horizontal level, support 1 is with bolts with slide bar 2; Slide bar 2 is interior with chute 4, connector 5 is installed on chute 4, be used for connecting two sounding rods 3 in left and right, two sounding rods 3 in left and right are bolted on the connector 5 of slide bar 2, can be for convenience detach, connector 5 can slide with before and after sounding rod 3 is on chute 4, at least 4 meters of slide bar 2 length, guarantee simultaneously two sounding rod 3 levels in left and right, perpendicular to the burner longitudinal center line; Be provided with scale on slide bar 2, be used for measuring the distance of test unit and burner, be provided with the distance that scale is used for measuring test unit and slide bar 2 on sounding rod 3.Before test, will install to split and bring burner hearth into, the front assembling of burner is complete, adjusts and tests.Partition after completing, the band flake hearth-tapping.
