Embodiment 1

[0035] A dual pipe and blowing with pulp density detecting device, such as a figure 1 and figure 2 Shown, comprising: a controller 1, 2 with pulp module, the detection module 3, and the gas supply source 4 barrel 5 with pulp, pulp module 2 and with the detection module 3 are respectively connected to the controller 1, and the gas supply source 4 with slurry 5 are connected to the tub 2 with pulp module and a detection module 3; 2 module with pulp slurry and for priming with slurry water to the tub 5, and then real-time detection by the detection module 3 and the ratio of the density level, and when the density level of compliance after the stop with slurry; when the time required with pulp, pulp with 2 modules also may be sewage, the tub 5 with the residual slurry discharging the slurry; gas supply source 4 for pulp with a detection module 2 and module 3 gas, and with pulp in order to achieve the detection of the double tube blowing.

[0036] The module 2 with slurry comprising: 2...

Embodiment 2

[0042] A method of detecting double pipe blowing with pulp density, such as image 3 As shown, including:

[0043] S1: The breather pipe end two different heights with slurry into the tub and the other end connected differential pressure sensor and a low pressure sensor.

[0044] The above steps, the high differential pressure sensor connected to the breather pipe, the breather pipe is connected to the low differential pressure sensor and the low pressure sensor. Low-pass and high-pass tube height difference between the trachea is L, the lower barrel snorkel and bottom of the barrel with slurry height difference is Ll; embodiment according to the present embodiment, the upper and lower vent tube snorkel with pulp were adherent mounted inside of the barrel .

[0045] S2: the vent gas supply to gas supply.

[0046] In the above step, the gas supply will blow through the trachea, air is conducted to the air tube will be positioned with pulp barrel high and low snorkel through the trac...

Abstract

The invention discloses double-pipe blowing slurry preparation and density detection equipment and a density detection method, the equipment comprises a controller, a slurry preparation module, a detection module, an air supply source and a slurry preparation barrel, the slurry preparation module and the detection module are respectively connected with the controller, and the air supply source and the slurry preparation barrel are respectively connected with the slurry preparation module and the detection module; the slurry preparation module comprises input equipment, interaction equipment, a working valve and an electromagnetic directional valve; the detection module comprises a differential pressure sensor and a low-level pressure sensor; the air supply source is used for blowing air; the pneumatic valve is high in response speed and large in output torque, so that the density and the volume of the prepared slurry can be more accurately controlled, and the waste of the slurry is reduced; the pneumatic valve is used, electric signal connection is not needed, the valve can work in a humid environment or diving, influences of environmental factors on the valve do not need to be considered, and the service life of the valve is prolonged; through double-pipe blowing type density detection, non-contact measurement can be achieved, and the phenomena of blockage and the like caused by thick slurry are avoided.

Description

Technical field [0001] The present invention relates to the field of instrumentation, in particular, a double pipe and blowing with pulp density detecting apparatus and method for detecting density. Background technique [0002] Now available on the market for the slurry density, temperature and volume are measured using the measuring method of separate test sensors, and each sensor signal acquisition and transmission are independent, the installation site for the slurry storage tank wall, if desired precision measuring the tub slurry volume of slurry storage, slurry storage barrels must complete processing. [0003] At present, intelligent system grout slurry three kinds of measurement sensors measuring parameters are the separate, this method has the disadvantage that measurement: easy to damp, easily water, difficult to maintain, difficult to clean. Inventive content [0004] Invention object of the present invention is: for the above-described problems, there is provided a d...
