Abstract
The utility model relates to a powder sampling device of a powder feeder with an impeller, which is used for the powder sampling check of the powder feeder with the impeller of a powder feeding system of a coal powder boiler in a power plant, and powder feeding systems in industries of construction materials, metallurgy, etc. The utility model is provided with an outer shell, wherein the outer shell is connected between a powder downward conveying opening and a blanking pipe of the powder feeder. A feeding opening on the upper surface corresponds to the powder downward conveying opening of the powder feeder. A discharging opening on the lower surface corresponds to the blanking pipe of the powder feeder. A powder collecting sealing bag is installed on the discharging opening. A frame of the powder collecting sealing bag is placed on the discharging opening. A sampling opening is arranged on the lateral side of the outer shell. The utility model has the advantages of reasonable structure, safety, simple and quick operation, small workload and accurate sampling.
Description
Technical field
The utility model relates to a kind of Impeller powder supplying machine powder sample device, is used for the Impeller powder feeder powder sampling verification of giving powder system that pulverized coal power boiler is given powder system and industries such as building materials, metallurgy.
Background technology
In industries such as generating plant, building materials, metallurgy, need granular material, as: the fuel coal dust is carried continuously, in the coal dust course of conveying, for safety, steady production, need carry out metering verifications such as weight to coal dust.At present, the powder of Impeller powder feeder sampling verification is generally adopted and will be descended powder mouth or tremie pipe to pull down, and coal dust is inserted in the bag carry out the weighing verification.Because of verification is a regular job, not only time-consuming but also contaminated environment, workload are big with the method, also influence the safety of powder-supply system.
Summary of the invention
It is a kind of rational in infrastructure, safe and reliable, simple to operate, quick that the purpose of this utility model is to provide, and workload is little, the Impeller powder supplying machine powder sample device accurately of taking a sample.
Impeller powder supplying machine powder sample device described in the utility model, have and be connected the shell between the powder mouth and tremie pipe under the machine supplying powder, the following powder mouth of top charging aperture machine supplying powder is corresponding, following discharging opening is corresponding with the tremie pipe of machine supplying powder, be fitted with collection powder sealing bag on the discharging opening, the framework of collection powder sealing bag is seated on the discharging opening, and the side of shell is provided with sample tap.
In the machine supplying powder normal course of operation, take out collection powder sealing bag, sample tap is flowed through shell directly to tremie pipe by the blind flange shutoff from the powder that following powder mouth gets off on the shell.When needing sampling, collection powder sealing bag is placed on the discharging opening of shell,, gets final product from the sample tap sampling of shell with the powder shutoff.Collection powder sealing bag has pliability, adapts to different discharging opening version, can be according to the alteration of form of discharging opening and arbitrarily change.Have certain adjustment performance, make better effects if of resilient material.
On sample tap, assemble stopple coupon, connect powder sample bag in the outer end of stopple coupon, make be connected and fixed with sampling operation more convenient.Be connected with pipe clamp designing between powder sample bag and stopple coupon, can make be connected and fixed more convenient to operate, quick.
Between collection powder sealing bag framework and discharging opening, set up sealing gasket, strengthen sealing property.
Be connected being designed to bolt between powder mouth under shell and the machine supplying powder and tremie pipe, be connected firmly, easy for installation.
The utility model Impeller powder supplying machine powder sample device is rational in infrastructure, and is safe and reliable, and simple to operate, quick, workload is little, and sampling accurately is beneficial to and applies.The metering verification that the utility model is finished coal dust and other powder with the Impeller powder feeder velocity measuring device 200420039691.8 and the Powdery material density measurement device 200420039688.6 of the applicant's development also can be used for other correlative technology field.
Description of drawings
Fig. 1, the utility model one example structure synoptic diagram.
Among the figure: 1, the framework 4 of powder mouth 2, shell 3, collection powder sealing bag, sealing gasket 5, tremie pipe 6, collection powder sealing bag 7, stopple coupon 8, powder sample bag pipe clamp 9, powder sample bag under the machine supplying powder.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, Impeller powder supplying machine powder sample device described in the utility model, have and be connected the shell 2 between the powder mouth 1 and tremie pipe 5 under the machine supplying powder, top charging aperture is corresponding with the following powder mouth 1 of machine supplying powder, following discharging opening is corresponding with the tremie pipe 5 of machine supplying powder, be fitted with collection powder sealing bag 6 on the discharging opening, the framework 3 of collection powder sealing bag 6 is seated on the discharging opening, be provided with sealing gasket 4 between collection powder sealing bag framework 3 and discharging opening, the side of shell 2 is provided with sample tap, be equipped with stopple coupon 7 on the sample tap, the outer end of stopple coupon 7 connects powder sample bag 9,7 of powder sample bag 9 and stopple coupons are fixedlyed connected with pipe clamp 8, and shell 2 is connected with 5 bolts of powder mouth 1 and tremie pipe under the machine supplying powder.
During sampling, powder is by the 1 access to plant shell 2 of powder mouth under the Impeller powder feeder, and the collection powder sealing bag 6 of flowing through compiles, and enters the sampling that powder sample bag 9 is finished powder via stopple coupon 7.When not taking a sample, take out collection powder sealing bag 6, sample tap is flowed through shell directly to tremie pipe by flange seal from the powder that powder mouth under the machine supplying powder gets off, and is normal operating condition.
