Abstract
The utility model provides an ore pulp concentration detection device. The ore pulp concentration detection device comprises an ore pulp pipeline, a differential pressure transmitter and two connecting pipes, wherein the two connecting pipes are provided with two flanges and two diaphragms. The ore pulp concentration detection device is characterized in that the ore pulp pipeline is arranged obliquely, the two connecting pipes with flanges and diaphragms are vertically arranged in positions of different heights on the oblique ore pulp pipeline respectively, and the two flanges are connected with the differential pressure transmitter through capillary pipes. According to the ore pulp concentration detection device, when the ore pulp pipeline stops conveying ore pulp, ore pulp and solid particulates in the connecting pipes can be enabled to vertically flow back to the ore pulp pipeline under the action of gravity, so that the blockage caused by the fact that the ore pulp and solid particulates remain in the connecting pipes is effectively prevented, the situation that the differential pressure transmitter can obtain actual ore pulp pressure difference in a timely and indirect manner is guaranteed, and the detection accuracy is further ensured.
Description
Technical field
The utility model patent relates to a kind of concentration detection apparatus, and especially a kind of device that pulp density is detected belongs to the densimeter technical field.
Background technology
The radiativity densimeter is used in existing ore dressing plant mostly, i.e. gamma-rays densimeter is because the gamma-rays densimeter adopts Se
137, Co
60In radioactive isotope as radiation source, belong to Radioactive instrument, need strictly take various radioactive shield measures during use, also must formulate strict working specification, the related maintenance personnel also must make regular check on health, so the production scene urgently wishes to have the non-radiation type densimeter to replace the gamma-rays densimeter.It is found that: when pulp density changed, its pulp density also had obvious variation, therefore can measure pulp density by the variation that detects pulp density.But the relation of pulp density and pulp density is not linear relationship, and its variation is relevant with the density of ore in the ore pulp, therefore need adopt intelligent algorithm to the processing of detection signal.For this reason, on ore pulp vertical uplift pipeline, at a distance of the position of certain height difference h, two pressure points are set, the horizontal connection tube of difference mounting strap flange and diaphragm, and between two flanges, connect differential pressure transmitter, with indirect acquisition ore pulp pressure difference value, this difference is h * p

Summary of the invention
Be detained for eliminating ore pulp, improve accuracy of detection, the utility model provides a kind of pulp density pick-up unit.
The utility model provides a kind of like this pulp density pick-up unit, comprise ore slurry pipeline, differential pressure transmitter, the connecting pipe of two flanged and diaphragms, it is characterized in that ore slurry pipeline is obliquely installed, two connecting pipes flanged and diaphragm are vertically set on respectively the differing heights position on the ore slurry pipeline of inclination, connect differential pressure transmitter by kapillary between two flanges, when stopping transfer ore pulp with convenient ore slurry pipeline, ore pulp in the connecting pipe and solid particulate matter are under Action of Gravity Field, vertically be back in the ore slurry pipeline, and can not cause delay, stop up, guarantee accuracy of detection.
The angle of inclination of described ore slurry pipeline is 30 °～60 °, in order to when guaranteeing the ore pulp proper flow, the connecting pipe of flanged and diaphragm is vertically arranged.
Described diaphragm arrangement is in the flange end, with indirect measurement ore pulp pressure differential.
The utlity model has following advantages and effect: adopt such scheme, can be when ore slurry pipeline stops transfer ore pulp, make ore pulp and solid particulate matter in the connecting pipe, flow in the ore slurry pipeline at the sagging straight gyrus of Action of Gravity Field, the obstruction that effectively prevents ore pulp and solid particulate matter in connecting pipe, to be detained and cause, guarantee that differential pressure transmitter can obtain actual ore pulp pressure differential in good time, indirectly, guarantees accuracy of detection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The pulp density pick-up unit that the utility model provides, comprise ore slurry pipeline 1, differential pressure transmitter 7, the connecting pipe 2 of two flanged and diaphragms, 5,45 ° of settings of ore slurry pipeline 1 inclination, flanged 3 and the connecting pipe 2 of diaphragm be vertically set on high position on the ore slurry pipeline 1 of inclination, flanged 6 and the connecting pipe 5 of diaphragm be vertically set on lower position on the ore slurry pipeline 1 of inclination, the poor h of height of formation between the two positions, connect differential pressure transmitters 7 by kapillary 4 between two flanges 3 and 6, diaphragm on two flanges 3 and 6 all is arranged on the flange end, with indirect measurement ore pulp pressure differential, and when ore slurry pipeline 1 stops transfer ore pulp, ore pulp in the connecting pipe 2 and 5 and solid particulate matter vertically are back in the ore slurry pipeline 1, thereby can not cause delay under Action of Gravity Field, stop up, guarantee accuracy of detection, such as Fig. 1.
