Abstract
The utility model relates to a liquid level alarm special for a pump pit, and the alarm is characterized in that two steel conduits are welded on a frame, and simultaneously, a top type travel switch is fixed on the frame by a screw. Floating balls are connected by an ejection pin to pass through a conduit, and are hung on the conduit at the upper part of the ejection pin through a semicircular top surface at the upper part of the ejection pin. The top type travel switch is connected with a leakage protector and an electric bell by an electric cable. The utility model can effectively avoid the phenomena caused by that accidents occur by the transverse drift of the floating balls without alarm, and the liquid level alarm is disabled because of the fatigue of the switch. The utility model has the advantages of simple material, low cost, convenient manufacture and corrosion resistance, and is especially beneficial for using under the condition of moisture, such as the pump pit. The top type travel switch is used to replace a primary cantilever type travel switch, the ejection pin is used to replace a flexible cord, and hollow white steel balls are used to replace boards to be taken as the floating balls, so that the precision and the accuracy of the liquid level alarm are greatly enhanced with putting an end to the occurrence of the accidents.
Description
Technical field
The utility model relates to a kind of pump hole liquid level alarm device that is used for mining processing industry, and particularly a kind of pump is cheated special-purpose liquid level alarm.
Background technology
Ore pulp in the mining processing industry transports with pump, and generally speaking, pump is placed in the operation place by unified, is commonly called as the pump hole.In actual production, sometimes because a variety of causes causes pump to burn motor or unexpected situation about having a power failure, pump will shut down; And at this time the ore pulp of the whole production flow process ore deposit case of giving that can continue to enter pump causes ore pulp excessive, directly enters the pump hole.If the production station workman does not in time find this situation, can cause the mineral syrup liquid in the pump hole to rise, make the motor water inlet, even flood motor, cause the situation of burning motor in enormous quantities, make enterprise suffer unnecessary economic loss.And the generation of this type of accident has been avoided in the use of liquid level alarm in the pump hole basically.Liquid level in pump hole surpasses in the warning line, and liquid level alarm warnings of will sounding reminds the production station workman in time to find, the generation of accident is effectively avoided in timely processing.Its design of liquid level alarm of the prior art is simpler, adopts the cantilevered travel switch, and flexible cord connects, and is cursory with the plank replacement, owing to be in the state that draws bob for a long time, easily causes cantilevered travel switch fatigue; Lateral drift takes place in plank easily that do cursory usefulness in addition when liquid level rises, these situations all can cause when accident occurring liquid level alarm not report to the police, and do not have corresponding effect, the generation that causes the accident.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is to reduce the instability of original liquid level alarm effectively, and the generation of fundamentally stopping pump hole accident provides a kind of pump to cheat special-purpose liquid level alarm.
The utility model pump is cheated special-purpose liquid level alarm content Description:
The utility model pump is cheated special-purpose liquid level alarm; it is characterized in that: on framework; weld two steel conduits; with screw top formula travel switch is fixed on the framework simultaneously; ball float couples together with push rod; pass conduit, a semicircular end face by push rod top hangs on the conduit on top, and top formula travel switch is connected with electric bell with earth leakage protective device with cable.
The utility model pump is cheated special-purpose liquid level alarm, and ball float is vertical with push rod to be cooperated owing to adopt, and is fixed on the framework with conduit, can effectively avoid the ball float lateral drift to cause and the phenomenon that accident is not reported to the police occur.Adopt top formula travel switch to replace original cantilevered travel switch, can avoid switch fatigue to cause the liquid level alarm failure phenomenon.The material that adopts is simple, and cost is low, and is easy to make, and corrosion-resistant, is particularly conducive under the environment of the such humidity in pump hole to use.Replace original cantilevered travel switch with top formula travel switch, replace flexible cord, do ball float, improved the precision and the accuracy rate of liquid level alarm greatly with hollow white steel ball instead of wood plate with push rod, the generation of stopping accident, and make very simple.
Description of drawings
Fig. 1 is that pump is cheated special-purpose liquid level alarm structural representation
Among the figure: the 1st, framework, the 2nd, white steel hollow float, the 3rd, conduit, the 4th, push rod, the 5th, top formula travel switch, the 6th, earth leakage protective device, the 7th, electric bell, the 8th, rectangular hole.
Embodiment
The utility model pump is cheated special-purpose liquid level alarm and is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, the utility model pump is cheated special-purpose liquid level alarm, by: framework 1, white steel hollow float 2, conduit 3, push rod 4, top formula travel switch 5, earth leakage protective device 6, electric bell 7 are formed.With diameter is that the white steel hollow ball of 180mm is done ball float 2, is that the push rod 4 of PPR couples together with ball float 2 usefulness screws with material; Simultaneously on the framework of making of angle steel again 1, weld two steel conduits 3, push rod 4 passes steel conduit 3, can play fixation like this, avoids the push rod lateral drift.On the top of push rod 4 a semicircular end face is arranged, push rod just can hang on the conduit of top like this.With two screws top formula travel switch 5 is fixed on the framework 1, formula travel switch 5 usefulness triple cables in top are connected to earth leakage protective device 6 and electric bell 7.Earth leakage protective device 6 can play a protective role, and avoids causing electric shock accidents.On framework 1, do simultaneously two rectangular holes 8, carry out height during convenient the installation and regulate.Be fixed on the metope by two rectangular hole 8 usefulness key screw frameworks 1.
When the liquid level in the pump hole was run into ball float above warning line, ball float rose under buoyancy function, made push rod rise, and end face will be run into top formula travel switch like this, makes circuit communication, and electric bell will ring, and plays the warning effect.
