Put, ensure the horn mouth face Hatch Opening 31 of the waveguide pipe 42 in measurement process of level-sensing device 40, so that it is guaranteed that level-sensing device 40 can be just
Really to the material-level measure mouth for entering feed bin correctly to show bin-level.
Specifically, according to one embodiment of present invention, the radial dimension of housing 10 is the radial direction of the lower end of level-sensing device 40
Twice of size.Level-sensing device 40, which is arranged on upper flange plate 20, makes waveguide pipe 42 be located in the chamber 11 of the formation of housing 10, wherein,
The radial dimension of the lower end of the waveguide pipe 42 of level-sensing device 40 is 10 radial dimension of half of housing.
The lower end of level-sensing device 40 is located at the top of lower flange 30 and is just located at the surface of Hatch Opening 31, and according to this hair
Bright one embodiment, the radial dimension of Hatch Opening 31 are more than the radial dimension of the lower end of level-sensing device 40.In other words, the footpath of Hatch Opening 31
To radial dimension of twice of the lower end that size is level-sensing device 40.
Preferably, according to one embodiment of present invention, the upper surface of the lower surface of level-sensing device 40 and lower flange 30 it
Between distance be 15-25mm.That is, the lower surface of the waveguide pipe 42 of level-sensing device 40 is located at the Hatch Opening 31 of lower flange 30
Surface, and the control of the distance between the lower surface of waveguide pipe 42 and Hatch Opening 31 is in 15-25mm.
Specifically, in certain specific embodiments of the invention, housing 10, upper flange plate 20 and lower flange 30 are distinguished
Be formed as steel plate, the thickness of housing 10 is 2-4mm, and the thickness of upper flange plate 20 and lower flange 30 is 4-6mm.In other words, shell
Body 10, upper flange plate 20 and lower flange 30 are made by steel plate, wherein, the thickness control of housing 10 is in 2-4mm, upper flange plate
20 and lower flange 30 thickness control in 4-6mm.
Thus, the part of level-sensing device 40 is located in the chamber 11 formed by housing 10, and in the top and bottom of housing 10 point
Not She Zhi upper flange plate 20 and lower flange 30, level-sensing device 40 is avoided granular material in the course of the work, reduce due to powder
Measuring error caused by shape material enters the lower end of level-sensing device 40, improve the service life of level-sensing device 40, and the level-sensing device
The manufacture craft of component 100 is simple, low manufacture cost.
According to one embodiment of present invention, housing 10, upper flange plate 20 and lower flange 30 are weldingly connected.Namely
Say, the upper surface of upper flange plate 20 and housing 10 is weldingly connected, and the lower surface of lower flange 30 and housing 10 is weldingly connected, and passes through
The upper surface that welding procedure first distinguishes upper flange plate 20 with lower flange 30 housing 10 is connected with lower surface, then by material position
Meter 40 is connected to form an entirety with upper flange plate 20 by flange, finally pacifies level-sensing device component 100 by lower flange 30
On feed bin.Thus, level-sensing device component 100 according to embodiments of the present invention, original level-sensing device 40 is inserted in feed bin
Form is changed into the form that level-sensing device 40 is placed in outside feed bin, level-sensing device 40 is avoided granular material in the course of the work, reduces
Measuring error caused by entering the lower end of level-sensing device 40 due to granular material.
As shown in figure 1, according to one embodiment of present invention, adpting flange 41 turns on provided with least one with chamber 11
Breather pipe 50, breather pipe 50 connects with high-pressure blast to improve the air pressure in chamber 11.Specifically, the adpting flange of level-sensing device 40
41 are provided with one or more breather pipe 50, and breather pipe 50 turns on the chamber 11 that the external world is formed with housing 10, that is to say, that
Breather pipe 50 connects in the external world with feed bin.
When granular material enters feed bin, lead to high-pressure blast into chamber 11 from breather pipe 50, make the inside of chamber 11 full of just
Pressure, the surrounding of waveguide pipe 42 in chamber 11 form hyperbar layer, make level-sensing device 40 when measuring the height of material in feed bin, can be with
Avoid granular material.Thus, the air pressure inside chamber 11 is more than the air pressure in feed bin, avoids because granular material enters material position
Measuring error caused by the lower end of meter 40, ensure that the normal work of level-sensing device 40, improves the service life of level-sensing device 40.
In certain specific embodiments of the invention, breather pipe 50 includes two, and two breather pipes 50 are respectively provided at material
The both sides of position meter 40.In other words, level-sensing device 40 is arranged on the center position of upper flange plate 20, in the adpting flange of level-sensing device 40
The both sides of level-sensing device 40 are respectively equipped with breather pipe 50 on 41.When granular material enters feed bin, by two breather pipes 50 to chamber
Lead to high-pressure blast in room 11, can make hyperbar layer is more quickly formed around the waveguide pipe 42 in chamber 11, reduce raising up for dust.
Thus, breather pipe 50 is installed on the adpting flange 41 of level-sensing device 40, makes shape in the chamber 11 of level-sensing device component 100
Into one blast, granular material can not enter in chamber 11 and in the waveguide pipe 42 of level-sensing device 40, avoid due to powder
Measuring error caused by material into the lower end of level-sensing device 40, ensure that the normal work of level-sensing device 40, improves level-sensing device 40
Service life.
It should be noted that the high-pressure blast led into chamber 11 can not also have moisture or other corrosive gas.Setting
When counting the specific size of the component of level-sensing device component 100, such as housing 10, the chi of the adpting flange 41 of level-sensing device 40 can be first measured
It is very little, the device is carried out according to the size of the adpting flange 41 of level-sensing device 40.Specifically, the highly desirable and level-sensing device 40 of housing 10
The length dimension of waveguide pipe 42 set, the size of upper flange plate 20 and lower flange 30 should be with the adpting flange of level-sensing device 40
41 size is consistent, and the size of the Hatch Opening 31 on lower flange 30 need to be according to the bell-mouthed size of the waveguide pipe 42 of level-sensing device 40
To determine to use to ensure that the device can be good at abutting joint, the welding of upper flange plate 20 and lower flange 30 and housing 10 needs
Ensure no-welding-seam to ensure the air-tightness of level-sensing device component 100, so as to meet the functional requirement of level-sensing device component 100.
