Abstract
The utility model provides a former coal bunker metering device that weighs on line all around installs weighing sensor additional at former coal bunker, and former coal bunker is connected through flexible coupling and feeder, hydraulic rod fix on former coal bunker and also quantity equally many with weighing sensor, the standard test weight hangs on hydraulic rod. The utility model discloses the coal volume to former coal bunker that can be more accurate is weighed, utilizes these data of weighing to check feeder and electronic belt conveyor scale's the degree of accuracy of weighing, makes things convenient for maintainer more in time to carry out the check -up to it effectively, and former coal bunker is weighed measurement system self accessible standard test weight and is realized online check -up function.
Description
Technical field
The utility model relates to the run coal bin Weighing device of coal-fired power plant.
Background technology
Current most of fuel-burning power plant, run coal bin is all adopted to add the configuration structure of feeder and direct-blowing type coal mill, and boiler fired coal amount is as the principal economic indicators of boiler, major part is all the data obtained by the weighing device of feeder, feeder has many types, such as: vibration coal feeder, reciprocating coal feeder, belt type coal feeder etc., be all often coordinate speed pickup to realize calculating coal-supplying amount by LOAD CELLS.The data of recycling coal conveyer belt scale as a comparison.
But there is following drawback in the method: 1, feeder verification is inconvenient, must to stop transport feeder, so error can only be eliminated by periodic check, maintenance work blindness is large 2, the distribution of multiple stage feeder is weighed, and be real-time dynamic weighing, error is larger 3, defeated coal belted electronic balance is arranged on the coal conveyer belt of inclination mostly, and error is larger.So, if Weighing can be carried out to run coal bin, then can more accurate comparison and the weighing data of checking feeder and belted electronic balance, prompting staff carries out verifying work in time.
In the coal quantity metering of run coal bin, the more individual metering of current use coordinates lifting of coal plough to fall to calculating by defeated coal belted electronic balance, and the actual range of the position of coal plough and belted electronic balance is comparatively far away and coal conveyer belt rotating speed is uneven, so these computing method exist comparatively big error.
Summary of the invention
The purpose of this utility model is to provide a kind of run coal bin online weighing measuring apparatus, and can weigh to the coal amount of run coal bin more accurately, the personnel that maintain easily verify it more timely and effectively.
The technical solution of the utility model is: a kind of run coal bin online weighing measuring apparatus, it is characterized in that installing LOAD CELLS additional in run coal bin surrounding, run coal bin to be connected with feeder by being flexible coupling, hydraulic push rod be fixed on run coal bin and also quantity identical with LOAD CELLS, standard test weight is suspended on hydraulic push rod.
The utility model run coal bin online weighing measuring apparatus, utilize and install high-precision LOAD CELLS additional at the support column place of run coal bin, utilize with feeder the intercommunication that is flexible coupling bottom run coal bin, the coal amount realizing run coal bin is weighed in real time, the weighing data of defeated coal belted electronic balance and feeder can be verified by this weighing device, the personnel that maintain easily verify it more timely and effectively, and run coal bin weighing system self realizes on-line testing function by standard test weight.
Accompanying drawing explanation
Fig. 1 is the utility model scenario-frame schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As shown in Figure 1, the utility model run coal bin Weighing device, by installing LOAD CELLS 1 additional in run coal bin surrounding, run coal bin 45 to be connected with feeder 6 by being flexible coupling.In course of normal operation, hydraulic push rod 2 is in the state of stretching out, and surrounding standard test weight 3 lifts and is on platform.When verifying, hydraulic push rod 2 is regained, and standard test weight 3 hangs on run coal bin 4, carrying out balance check and full scale verification, also in operational process, can carry out linear parity by the counterweight loading varying number by walking sky run coal bin.Utilize the Weighing data of run coal bin can check comparison to the weighing data of belted electronic balance and feeder.
As shown in Figure 2, eight LOAD CELLS 1 have evenly been installed additional in run coal bin surrounding, hydraulic push rod 2 be fixed on run coal bin 4 and also quantity and LOAD CELLS 1 as many, multiple spot is weighed when verifying and can be increased the weight of single LOAD CELLS, to test the homogeneity of each LOAD CELLS, equivalent design can improve the accuracy of verification.
