Radar level gauge
Technical field
This utility model is related to level gauge apparatus field, particularly a kind of radar level gauge being applied to stirring flow container.
Background technology
By the use of microbial culture medium as catalyst carry out hydration reaction when, a large amount of foams can be produced.Because culture fluid can
To reuse, after completion of the reaction variable amount of reactant liquor is stayed in kettle so that next time uses.Due to culture fluid during stirring
Internal pressure can change, and can not accurately be measured using pressure-type liquidometer, can only select radar level gauge, but stir
When mixing, nutritional solution can produce a large amount of foams again, and the presence of foam can make a big impact to the metering of radar level.Impact measurement
Precision, and when stirring, the impact of culture fluid can affect the fastness of liquidometer.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is specifically described.
As illustrated, a kind of radar level gauge, including liquid level tube 1, the lower end of described liquid level tube 1 is provided with buffer mouth 2, institute
The top stating liquid level tube 1 is provided with level radar 3, and described liquid level tube 1 is located in stirred tank 4, described liquid level tube 1 and stirred tank 4
Between fixedly mounted by fixed mount 5, kickboard 6 is installed in described liquid level tube 1, the upper end of described kickboard 6 is provided with tablet
7, the lower end of described kickboard 6 is provided with balancing weight 8.
Described liquid level tube 1 is the metal tub structure being disposed vertically, and described liquid level tube 1 and described buffer mouth 2 are once to cast
Cause the overall structure of type, described buffer mouth 2 is cone barrel structure, the upper end diameter of described buffer mouth 2 and the institute being disposed vertically
The bottom diameter stating liquid level tube 1 is equal, and the bottom diameter of described buffer mouth 2 is more than the top end diameter of described buffer mouth 2, described slow
2 the distance between bottom surface and described stirred tank 4 inner bottom surface of blurting out is 1-15cm.
Described liquid level tube 1 is welded to connect with described fixed mount 5, and described fixed mount 5 is connected with described stirred tank 4 riveted, institute
The quantity stating fixed mount 5 is multiple.
Described kickboard 6 and described tablet 7 bonding connection, described kickboard 6 is foam kickboard, described balancing weight 8 with described
Kickboard 6 bonding connection, described balancing weight 8 structure annular in shape, the inwall damping of the outer shroud of described balancing weight 8 and described liquid level tube 1
Connect.
Restraining position ring block 9 is installed in the junction of described buffer mouth 2 and liquid level tube 1, and described spacing ring 9 is welded with described liquid level tube 1
Connect in succession.
The top of described liquid level tube 1 is provided with liquid level precaution device 10, described liquid level precaution device 10 and described level radar 3 electricity
Connect, the early warning distance of described liquid level precaution device 10 is less than the axial length of described liquid level tube 1.
Before installation, first spacing ring 9, level radar 3, fixed mount 5 and described liquid level tube 1 are fixed, during installation, by solid
Determine frame 5 liquid level tube 1 is fixing with stirred tank 4, now should be noted to determine the length of described liquid level tube 1 according to the specification of stirred tank 4
The distance of the degree and described buffer mouth 2 bottom surface bottom apart from stirred tank 4.
During use, when stirred tank 4 is started working, liquid level can shake, and described buffer mouth 2 utilizes entrance section area
Change, to impact buffer mouth 2 bottom fluid enter row buffering, thus reach that row buffering is entered to described liquid level tube 1 internal flow
Purpose, can also play simultaneously a part prevent foam from entering the purpose in liquid level tube 1.
Described level radar 3 is monitored apart from the position of level radar 3 to described tablet 7, instead of level radar 3
Detection to page height, even if pour into foam in described liquid level tube 1 do it is also possible to evade foam to level radar 3 detection
Disturb.
Described kickboard 6 can ensure that described tablet 7 is located at the surface of liquid in liquid level tube 1, and described balancing weight 8 is permissible
Make that described tablet 7 is more stable to make tablet 7 do damped motion with respect to internal flow when stirred tank 4 works, will not be due to
The accuracy that liquid fluctuating is excessive and affects liquid level metering.
Described liquid level precaution device 10 can be monitored to liquid level, when liquid level is too high or too low, makes
Early warning, prevents foam from entering in liquid level tube 1, and described spacing ring 9 prevents kickboard 6 from spilling from described liquid level tube 1.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
