The utility model has the advantages of simple structure, simple to operate, reaction sensitivity and excellent in use effect, after disposing this protection device, the condition that can avoid the pump body to damage takes place.
Description
Technical field
The utility model is specifically related to a kind of reactor discharging pump automatic safety device.
Background technique
In the production process of thickness reaction liquid, usually adopt gear pump, magnetic drive pump etc. as discharging pump, in real work, turn after material terminates and there is no timely termination of pumping due to a variety of causes, pump depletion phenomenon will be gone out, easily cause pump housing damage accident.Normal conditions, install Tuning Fork Switch and form protecting device of unloading pump bottom reactor; The working principle of Tuning Fork Switch by a pair piezoelectric crystal be arranged on tuning fork pedestal, tuning fork is vibrated under certain resonant frequency.When the tuning fork of Tuning Fork Switch contacts with measured medium, the frequency of tuning fork and amplitude will change, and these changes of Tuning Fork Switch are detected by smart circuit, process and convert it to a switching signal.Under normal circumstances, because some reaction liquid density, viscosity are comparatively large, very easily adhere on Tuning Fork Switch, cause collection signal mistake, even if after material in reactor is found time, discharging pump still can not stop, and causes pump housing damage accident.
Model utility content
The purpose of this utility model is to overcome prior art defect, provides a kind of reactor discharging pump automatic safety device.
Concrete technological scheme of the present utility model is as follows:
A kind of reactor discharging pump automatic safety device; comprise a reactor; also comprise a dispensing valve, a pneumatic ball valve, a Tuning Fork Switch, a control unit and a discharging pump; the bottom of reactor is located at by dispensing valve, pneumatic ball valve and discharging pump; and connected successively by pipeline; the detecting head of Tuning Fork Switch is located in the pipeline between dispensing valve and pneumatic ball valve, and the input end of control unit is electrically connected with Tuning Fork Switch, and the output terminal of control unit is electrically connected with the switching circuit of discharging pump.
In a preferred embodiment of the present utility model, the pipeline between described dispensing valve and pneumatic ball valve is vertical pipeline.
In a preferred embodiment of the present utility model, also comprise an interlock, described pneumatic ball valve is connected with described discharging pump by this interlock.
In a preferred embodiment of the present utility model, described discharging pump is gear pump or magnetic drive pump.
In a preferred embodiment of the present utility model, described reactor is polycarboxylic acids reactor.
The beneficial effects of the utility model are:
1, the utility model comprises a reactor, also comprise a dispensing valve, one pneumatic ball valve, one Tuning Fork Switch, one control unit and a discharging pump, dispensing valve, the bottom of reactor is located at by pneumatic ball valve and discharging pump, and connected successively by pipeline, the detecting head of Tuning Fork Switch is located in the pipeline between dispensing valve and pneumatic ball valve, the input end of control unit is electrically connected with Tuning Fork Switch, the output terminal of control unit is electrically connected with the switching circuit of discharging pump, there is structure simple, easy for installation, be quick on the draw the advantage good with using effect, after configuring this protective gear, the situation that the pump housing can be avoided to damage occurs,
2, the detecting head of Tuning Fork Switch of the present utility model is not install and reactor autoclave body bottom, but it is inner to be installed on discharge port vertical pipeline bottom reactor, after in reactor, polycarboxylic acids mother liquor is found time, due to the negative pressure that the operation of pump produces, impel the liquid adhered to on Tuning Fork Switch to depart from, after tuning fork collects model, automatic control device cuts off discharging pumping source in time, make pump out of service, thus avoid damaging the pump housing;
3, the utility model also comprises an interlock, and described pneumatic ball valve is connected with described discharging pump by this interlock, and while pump stops, interlock cuts out pneumatic ball valve at the bottom of still, and the synthesis that namely reactor can continue next cycle is produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the technical solution of the utility model be further detailed below by way of embodiment and describe.
As shown in Figure 1, a kind of polycarboxylic acids reactor discharging pump 7 automatic safety device, comprise a reactor 1, also comprise a dispensing valve 2, one pneumatic ball valve 3, one Tuning Fork Switch 4, one interlock 5, one control unit 6 and a discharging pump 7 (being preferably gear pump or magnetic drive pump), dispensing valve 2, the bottom of reactor 1 is located at by pneumatic ball valve 3 and discharging pump 7, and connected successively by pipeline, the detecting head of Tuning Fork Switch 4 is located in the vertical pipeline between dispensing valve 2 and pneumatic ball valve 3, the input end of control unit 6 is electrically connected with Tuning Fork Switch 4, the output terminal of control unit 6 is electrically connected with the switching circuit of discharging pump 7, pneumatic ball valve 3 is connected with discharging pump 7 by interlock 5.Said apparatus have structure simple, easy for installation, be quick on the draw and advantage that using effect is good, after configuring this protective gear, the situation that the pump housing can be avoided to damage occurs.Preferably, control unit 6 and interlock 5 adopt the JX-300XP system of SUPCON.
Working procedure of the present utility model is as follows: dispensing valve 2 is in normally open, starts discharging pump 7, and interlock 5 sends instruction and opens reactor 1 end pneumatic ball valve 3, realizes turning material process, at the end of turning material, in reactor 1, liquid level drops to the detecting head position of Tuning Fork Switch 4, the negative pressure produced due to discharging pump 7 causes the liquid adhered on Tuning Fork Switch 4 detecting head to depart from, Tuning Fork Switch 4 sends a trigger signal, after control unit 6 obtains trigger signal, namely the switching circuit to discharging pump 7 sends power-off termination of pumping instruction, timely cut-out discharging pump 7 power supply, make pump out of service, thus avoid damaging the pump housing, when discharging pump 7 is out of service, interlock 5 sends instruction and cuts out pneumatic ball valve 3, terminate to turn material process, the synthesis that namely reactor 1 can continue next cycle is produced.
The above, be only preferred embodiment of the present utility model, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
