Abstract
The invention discloses a kind of novel no axle envelope sand mills to feed fluid level control device.The thrust that the flowing of slurry generates in sand mill feed hopper, when acting on the backgauge piece of upper limit bull stick lower end, upper limit bull stick upper end is due to leverage and close proximity to switch, electric signal transmission is converted to control cabinet by distance signal close to switch, and control cabinet realizes effective control to liquid level by control feed pump.
Description
Technical field
The present invention relates to a kind of novel no axle envelope sand mills to feed fluid level control device, belongs to sand mill technical field.
Background technique
Sand mill is to complete the broken of material using collision, shearing and the extruding between abrasive media and material.At present
Vertical grinding machine be that the height of liquid level in feed hopper is controlled by the speed of control input and output material pump, really realize automatic
Change, and this mode is difficult to control, and is easy to appear the phenomenon that causing slurry to leak due to velocity error long time integration, causes
Material waste and equipment pollution.We also once considered the fluid level control device such as infrared ray of mainstream in the market, ultrasonic wave, connect
The liquidometers such as touch resistance-type, magnetic inductive, heat-conducting, but these are not suitable for using in the feed hopper of sand mill, it is main
Reason is wanted to have two: first is that above-mentioned liquid level controlling instrument explosive-proof grade cannot reach the requirement of chemical, second is that since sand mill is ground
During mill, inevitably there is slurry to be adhered to the surface of inductive head and lead to the reduction of its susceptibility, and then induction is caused to be failed.
Summary of the invention
The invention solves a technical problem be just to provide a kind of fluid level control device, solve sand mill feeder process
In due to input and output material flow it is different caused by slurry leak the phenomenon that, and this device runs smoothly reliably, long service life.
The invention discloses a kind of novel no axle envelope vertical grinding machines to feed fluid level control device, this device is by close switch
It (is a kind of no-spark encapsulated using incombustible material as shell, fire proofing, without fever, waterproof, shockproof, corrosion-resistant close to switch
Safety switch), upper limit pedestal and the upper limit bull stick composition.When the liquid level of slurry in feed hopper is higher than fluid level control device upper limit shelves
When the backgauge piece of bar, backgauge piece is rotated clockwise generated thrust by slurry and connects swing rod upper end close proximity to switch
Sensor on nearly switch will be converted into electric signal apart from model, be transferred to control cabinet, feed pump stops working, in feed hopper
Liquid level decline；On the contrary, upper limit bull stick returns just, and feed pump works when liquid level is lower than backgauge piece.
Detailed description of the invention
Fig. 1 is the location drawing of sand mill locating for fluid level control device；Fig. 2 is the working principle diagram of fluid level control device；Figure
3 be the structure composition figure of fluid level control device.
Invention is further described in detail in the following with reference to the drawings and specific embodiments.Embodiments of the present invention are as schemed
1, shown in Fig. 2.The fluid level control device 10 close to switch 11, upper limit bull stick 12 and upper limit pedestal 13 by forming, and building block is such as
Shown in Fig. 3.When the liquid level of slurry in feed hopper 3 be higher than 10 upper limit lever of fluid level control device backgauge piece when, backgauge piece by
Slurry rotates clockwise generated thrust and upper limit swing rod angle is made to generate deviation, and proximity is leaned on due to leverage in swing rod upper end
Nearly switch, fluid level control device is in running order at this time, converts electric signal for distance signal close to the sensor on switch,
It is transferred to control cabinet, feed pump stops working, and charging stops, and discharges and also continuing；When liquid level is lower than backgauge piece, the upper limit turns
Bar returns just, and fluid level control device is in halted state at this time, and feed pump works.
The novel no axle envelope vertical grinding machine charging fluid level control device of one kind disclosed by the invention can be good at solving vertical
Formula sand mill level control problem, is quick on the draw, securely and reliably.
The above is only embodiments of the present invention, are not intended to limit the scope of the invention, all to utilize this explanation
The equivalent structure that book and accompanying drawing content are done is applied to sand mill field, within the protection domain of this patent..
