The utility model enables the measurement of the density of the powdery material to be accurate. The utility model which has good working performance is favorable for the industrial production. The utility model can be widely used for the real-time measurement of the density of the coal powder of a powder feeding system of a coal powder boiler in a power plant and powder feeding systems of construction material industry, etc., and can be applied to other similar fields.
Description
Technical field
The utility model relates to a kind of improved Powdery material density measurement device, in particular for the measurement of pulverized coal power boiler to the coal dust density of the coal supply system of powder system and building material industry etc.
Background technology
In industries such as power plant and building materials, need be to granular material, carry continuously as the fuel coal dust, in the coal dust course of conveying, for safety, steady production, need the stable conveying of control coal dust, the general control method that adopts is to regulate by the density of measuring coal dust, because under the situation of the hopper of weighing of fixed volume, coal dust weight is only relevant with coal dust density.For industrial normal operation, need accurately measure control to coal dust conveying situation, the patent No. of the applicant design is that 200420039688.6 Powdery material density measurement device can be measured accurately, but find in using, LOAD CELLS places the hopper of weighing, cause its operating ambient temperature higher, reach 130 degree, directly affect the life-span and the serviceability of LOAD CELLS, and, latch up phenomenon appears in also find the to weigh discharging opening of hopper easily, also directly affects the normal operation and the measurement result of equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of improved Powdery material density measurement device, and it is more accurate to measure, and serviceability is better.
Improved Powdery material density measurement device described in the utility model, the hopper of weighing places the measurement cavity that is isolated into by material baffle, the hopper of weighing has charging aperture and discharging opening, it is characterized in that establishing the LOAD CELLS insulating space at the top of measuring cavity, weigh hopper by steel cable be suspended on LOAD CELLS weigh a little on.
LOAD CELLS is isolated setting, and the operating ambient temperature of LOAD CELLS is reduced to below 80 degree, has guaranteed the serviceable life and the serviceability of LOAD CELLS, thereby has guaranteed measurement result accurately.
In order to obtain good measurement performance, between steel cable and measurement cavity and insulating space, and measure between cavity and insulating space and establish seal, as O-ring seal, sealing gasket, obturating cup etc.
Hang the disturbance steel wire in the hopper of weighing, the disturbance steel wire passes the discharging opening of the hopper of weighing, and the bottom of disturbance steel wire is connected with whipple hammer.In the blanking process, the swing of whipple hammer is rocked the disturbance steel wire, and the steel wire that rocks constantly touches discharging opening, makes the powder blanking unobstructed, has avoided the discharging opening latch up phenomenon, has further guaranteed the normal operation of equipment and the accuracy of measurement result.
The utility model makes the measurement of granular material density more accurate, serviceability is better, be beneficial to commercial production, be widely used in the real-time measurement of pulverized coal power boiler, also can be applicable to other approximate field to the coal dust density of the coal supply system of powder system and building material industry etc.
Description of drawings
Fig. 1, the structural representation of the utility model one embodiment under application state.
Among the figure: 1, power transportation pipe 2, insulating space 3, scales emphasis 4, sensor 5, silica gel sealing bowl 6, support 7, insulcrete 8, O-ring seal 9, steel wire 10, the hopper 11 of weighing, measurement cavity 12, whipple hammer 13, material baffle 14, passage.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, improved Powdery material density measurement device described in the utility model, the hopper 10 of weighing places the measurement cavity 11 that is isolated into by material baffle 13, the hopper 10 of weighing has charging aperture and discharging opening, it is characterized in that the top of measuring cavity 11 is provided with LOAD CELLS insulating space 2, the hopper 10 of weighing is suspended on the scales emphasis 3 of weighing by steel cable.Be provided with O-ring seal 8 and silica gel sealing bowl 5 between steel cable and measurement cavity 11 and the insulating space 2, measure cavity 11 and 2 of insulating spaces and can set up sealing gasket.Weighing is hung with steel wire 9 in the hopper 10, and steel wire 9 passes the discharging opening of the hopper 10 of weighing, and the bottom of steel wire 9 is connected with whipple hammer 12.Support 6 is below sensor 4, and insulcrete 7 is below support 6.
In application process, keep apart with the coal dust logistics corridor by will weigh hopper 10 of material baffle 13, coal dust in the power transportation pipe 1 drops in the hopper 10 of weighing by passage 14, finish by sensor 4 and to weigh, and through the normally equipped weighing-up wave data processing equipment in outside with weighing-up wave handle, output, can realize long-distance transmissions.In the blanking process, the swing steel wire 9 of whipple hammer 12 rocks, and the steel wire 9 that rocks constantly touches discharging opening, makes the powder blanking unobstructed, has avoided the discharging opening latch up phenomenon.
