Specific implementation mode
To make the purpose of this utility model, technical solution and advantage be more clearly understood, below in conjunction with the utility model
Attached drawing in embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment be only the utility model a part of the embodiment, instead of all the embodiments.
Solid granulates slurry pressure measuring unit in the prior art, pressure sensor are in direct contact slurry, slurry flow process
In the sensing head of pressure sensor be ground cause the service life of sensor very low.And due to the slurry graininess feature
The pressure value pulsating quantity measured is larger, is unfavorable for pressure data acquisition operation, and measurement result is inaccurate.Furthermore pressure sensor
It is in direct contact slurry to be easy to form dead angle slurry at the screw hole for making pressure sensor, often goes out to form siccative in screw hole and block, make
Pressure sensor is unable to measure slurry pressure.
In consideration of it, solid granulates slurry pressure measuring unit provided by the utility model, be provided between oil pocket and material chamber every
Diaphragm, such slurry make the oil medium in diaphragm deformable squeeze oil pocket, pressure pass into generating pressure to diaphragm after pan feeding chamber
Sensor detects the pressure of oil medium, to realize the detection for the pressure given to slurry.In this way, pressure sensor need not be direct
Slurry is contacted, the defect for causing service life short pressure sensor due to the grinding of slurry is avoided.And pressure sensor is logical
It crosses the pressure given of detection oil medium and realizes detection to the pressure of slurry, and since the pulsating quantity of oil medium is smaller, relatively it is conducive to
Pressure data acquires operation, and measurement result is more accurate.
The technical solution of the utility model embodiment offer is provided with reference to the accompanying drawings of the specification.
Fig. 1 is referred to, the utility model embodiment provides a kind of solid granulates slurry pressure measuring unit, which can
To include material chamber 11, oil pocket 12, diaphragm 13 and pressure sensor 14.Wherein, material chamber 11 can be used for carrying externally input
Solid granulates slurry.Oil pocket 12 can be connect with material chamber 11, be located at the top of material chamber 11, for carrying oil medium.Diaphragm 13
It can be located between material chamber 11 and oil pocket 12.Pressure sensor 14 can be arranged in the top of oil pocket 12, for detecting solid-state
Granule material slurry leads to the pressure that oil medium is given.
As shown in Figure 1, in slurry into after pan feeding chamber 11, with the flowing of slurry, diaphragm 13 bears the pressure of slurry, when
The pressure that diaphragm 13 is subject to makes diaphragm 13 be deformed, and such diaphragm 13 will squeeze the oil medium in oil pocket 12,
Make oil medium squeeze pressure sensor 14.Pressure sensor 14 measures the pressure that oil medium is given, to realize measurement slurry
The pressure given.
The embodiment of the present invention is provided with diaphragm 13 between oil pocket 12 and material chamber 11, and pressure sensor 14 is arranged in oil pocket
On 12, in this way, pressure sensor 14 need not be in direct contact slurry, so that it may to realize the pressure for measuring slurry and giving, avoid
