Summary of the invention
For above-mentioned situation, for overcoming prior art defect, the object of the utility model is just to provide a kind of pick-up unit of ore dressing flotation cell slurry level, can effectively solve high concentration ground paste and stop up instrument measurement mouth, barrier film instrument because of diaphragm apparatus can not be with slip fully in conjunction with producing measuring error, affect the accuracy of ore dressing floatation process operation, cleaning sampling pipe need be stopped using flotation cell, the problem that production efficiency is low.
The technical scheme that the utility model solves is, comprise pressure seal and measuring channel, pressure seal is made up of upper body and lower body, upper body, lower body is fixed together through joint flange sealing, upper body central upper portion has the outlet being connected with the measurement mouth of pressure measuring instruments, lower body lower central has import, the outlet of import and threeway measuring channel is communicated with, between the joint flange of upper body and the joint flange of lower body, be equipped with on one-tenth placed separately pressure seal inner chamber, the diaphragm of rubber of lower two chambers, upper chamber is connected through the measurement mouth of the pressure measuring instruments on outlet and top, lower chambers is connected through the outlet of import and threeway measuring channel, on the sampling induction pipe of threeway measuring channel, primary sample valve is housed, on the sewage draining exit pipe of threeway measuring channel, sewage draining valve is housed.
The liquid level that the utility model is applicable to flotation cell high concentration ground paste medium detects, and measuring-signal is accurate, reliable, can be continuously produced, and production efficiency is high, and simple in structure, is easy to repair and maintenance, handled easily.
Brief description of the drawings
Fig. 1 is the utility model structural front view.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Provided by Fig. 1, structure of the present utility model is, comprise pressure seal and measuring channel, pressure seal is made up of upper body 10a and lower body 10b, upper body, lower body is fixed together through joint flange sealing, upper body 10a central upper portion has the outlet 3a being connected with the measurement mouth of pressure measuring instruments 1, lower body 10b lower central has import 3b, the outlet 13 of import 3b and threeway measuring channel 7 is communicated with, between the joint flange 11a of upper body and the joint flange 11b of lower body, be equipped with on one-tenth placed separately pressure seal inner chamber, the diaphragm of rubber 5 of lower two chambers, upper chamber 2 is connected through the measurement mouth of the pressure measuring instruments 1 on outlet 3a and top, lower chambers 4 is connected through the outlet 13 of import 3b and threeway measuring channel 7, on the sampling induction pipe 9 of threeway measuring channel, primary sample valve 8 is housed, on the sewage draining exit pipe 12 of threeway measuring channel, sewage draining valve 6 is housed.
Described primary sample valve 8 and the bore of sewage draining valve 6 are greater than 60mm, effectively seal slip; Described pressure measuring instruments 1 is for having the differential pressure pickup of 4-20MA signal feedback; The diameter of the outlet 3a of described pressure seal is greater than 50mm; In described upper chamber 2, oil medium is housed; The joint flange 11a of described upper body and the joint flange 11b of lower body are the circle that structure is identical, and the periphery of upper body and the corresponding connection of lower body is fixed together with the joint flange of upper body and the joint flange planar central of lower body respectively.
The utility model adopts pressure seal, when use, in upper chamber 2, oil medium is housed, the measurement mouth isolation of slip and pressure measuring instruments, use oil medium to carry out pressure conduction, according to differential pressure pickup instruction measurement point force value, through density, pressure converts and draws measurement point liquid level, thoroughly solve slip blockage problem, use primary sample valve and sewage draining valve decomposition pressure sampling loop, in the time measuring mouth obstruction, change by valve, use simple tool directly to probe into block clearing in sampling pipe, realization does not stop online flotation cell measurement line is carried out to clean-up operation.
In the time specifically installing and using, first by being mounted to measuring position, flotation cell bottom shown in Fig. 1, by the oil medium that adds pressure to transmit in the upper chamber of pressure seal (secondary chamber) 2, make oil medium just not have excess pressure spacer assembly outlet position, before setting pressure measurement instrument, first to filling identical oil medium in the measurement mouth of pressure measuring instruments, be then threaded io the secondary chamber 2 of pressure seal by M20.Close sewage draining valve 6, open valve 8 one time, slip is by the lower chambers (chamber) 4 that samples induction pipe 9 and enter pressure seal, and by pressure signal transmission to secondary chamber, become after sending and reach control desk display measurement point liquid level through pressure measuring instruments.The utility model can, according to institute's measuring pressure value, change the diaphragm of rubber of different-thickness, to ensure measuring accuracy.
In the time that measurement point stops up, can open blowoff valve 6, foreign matter is gone out or used iron wire probe into by groove internal pressure and in groove, clear up foreign matter, because adopting pressure seal, the import of pressure measuring instruments can not stopped up by slip, and the outlet of pressure seal is because the good oily matter of mobility also can not stop up.
Above-mentioned is only the embodiment providing; for embodiment of the present utility model is described; the utility model is not limited in above-described embodiment; the identical equivalence of essence that every those skilled in the art make in scope of the present utility model changes, retrofits, adds or replaces, and all belongs to protection domain of the present utility model.
Compared to the prior art the utility model, has following advantage: on-line monitoring flotation unit slurry level changes continuously, and liquid level signal teletransmission to control desk is monitored.Measure highly sensitive, accurately and reliably.Solve flotation phosphoric acid, concentration is higher, easily to instrument measurement mouth latch up phenomenon, and barrier film instrument is out of shape the insensitive measuring error that cause with the factor such as slip contact area is little, barrier film material to low-pressure because of conventional barrier film.The utility model is provided with sample cock (i.e. a valve) and sewage draining valve, and easy cleaning sampling pipe solves because of the inactive dry and hard blocking pipe situation of slip causing of flotation cell short-term.
