Description
Technical field
The utility model relates to a kind of warning device, relates in particular to a kind of thickener high concentration autoalarm.
Background technology
Thickener is applicable to the processed of the concentrate and tailings in ore dressing plant, is widely used in the industries such as metallurgy, chemical industry, coal, significant to improving recycling water utilization rate and underflow transportation concentration and protection of the environment.At present, the thickener that ore dressing plant is used is mostly center driving thickener, and this thickener forms by concentrating well, harrow frame, gearing, cake frame lifting gear and charging gear etc.
Thickener is to prevent that the accident that in well, ore pulp excessive concentration causes shaft bottom alluvial sludge to hinder harrow frame operation (being commonly called as " kill-job ") from occurring in operational process, guarantee that the concentration of ore pulp in large well is lower than the maximum concentration value of a permission, need the every two hours lower quality of getting a certain amount of underflow ore pulp to shaft bottom with sampling box and weighing ore pulp of post personnel, contrast again concentration table and calculate concentration, if find that concentration is elevated to dangerous values and just reports to operation area.This metering system has not only increased the labour intensity in post, and wants certain interval of time between twice measurement, can not carry out Real-Time Monitoring to concentration, so just makes " kill-job " accident likely occur.
Summary of the invention
The purpose of this utility model is to provide a kind of thickener high concentration autoalarm, can the large well of Real-Time Monitoring in pulp density whether higher than the maximum concentration value allowing, make monitoring more accurately coherent and alleviate the labour intensity in post.
The purpose of this utility model realizes by following technical proposals:
A kind of thickener high concentration autoalarm is characterized in that comprising stationary installation, connecting rod, levitation device and alarm, described stationary installation comprises a column, on column, along same level direction, be provided with two cantilevers, and be arranged on cantilever and the radial limiting device of consistency from top to bottom; Described connecting rod comprises a stock and is fixed on the boss of also close stock upper end on stock; Described levitation device is an open circles conical vessel, in-built counterweight counterweight sheet; Boss near stock upper end is suspended on radial limiting device, and lower end connects levitation device; In stationary installation and near the position on stock top, contactor is installed, by wire, is connected with alarm.
Describedly be arranged on cantilever and the radial limiting device of consistency from top to bottom is comprised of fixture.
Described stock is comprised of some sections of quarter butts, between quarter butt by screwed connection.
Described open circles conical vessel is conical, by upper cover and whorl of base, is tightly connected.
Described stationary installation is E type structure, and contactor is arranged on to be gone up on a cantilever most, and this cantilever connects on column by bolt.
The utility model, according to law of buoyancy, makes the gravity of levitation device and connecting rod equal it by plus-minus counterweight counterweight sheet and arranges the buoyancy that ore pulp produces when allowing maximum concentration, compared with prior art have following useful technique effect:
Originally surveying concentrated large well concentration is all to measure by post manual operation, and the utility model can be monitored automatically; There is inaccurate incoherent factor in manual measurement originally, and the utility model can make measurement result more coherent; Originally can only lean on post to report measurement result, the utility model alarm bell warning lamp is while automatic alarm inside and outside pump house, more directly perceived; The utility model is for concentrated large well specialized designs, compare commercially available all types of densimeters have simple in structure, with low cost, install and use easy to maintenance, be not subject to the advantages such as any impurity medicament affects.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of thickener high concentration autoalarm is characterized in that comprising stationary installation 3, connecting rod 4, levitation device 5 and alarm 6.Described stationary installation 3 comprises a column 31, on column 31, along same level direction, is provided with two cantilevers 32, and is arranged on cantilever 32 and the radial limiting device 33 of consistency from top to bottom; Described connecting rod 4 comprises a stock 41 and is fixed on the boss 42 of also close stock upper end on stock 41; Described levitation device 5 is an open circles conical vessel, in-built counterweight counterweight sheet 51; Boss 42 near stock 41 upper ends is suspended on radial limiting device 33, and lower end connects levitation device 5; In stationary installation 3 and near the position on stock 41 tops, contactor 7 is installed, by wire, is connected with alarm 6.
The column 31 of stationary installation 3 is fixed on concentrated large well gear frame and walks on the security guardrail 2 of bridge, and the radial limiting device 33 being arranged on cantilever 32 is comprised of fixture, and the effect of fixture is that restriction stock 41 can only move up and down.Connecting rod 4 is suspended on fixture by the boss 42 of upper end, and lower end connects levitation device 5.Levitation device 5 is an open circles conical vessel, by upper cover 52, be connected with base 53 thread seals, open upper cover 52, in-built counterweight counterweight sheet 51, the effect of levitation device 5 is to move up and down according to the variation drivening rod 4 of buoyancy, and profile is saved bit by bit sludge and affected measuring accuracy for taper shape can reduce upper surface.The position that stationary installation 3 tops face connecting rod 4 is contactor 7, and the emergency alarm bell indoor with post operation with the alarm 6 on top by wire is connected.When connecting rod 4 moves upward, circuit is connected in the top pressing contact 7 of bar, alarm 6 flickers when now reporting to the police bell ring.
Described stock 41 can be comprised of some sections of quarter butts, between quarter butt by screwed connection.Stationary installation is E type structure, and contactor 7 is arranged on to be gone up on a cantilever most, and this cantilever connects on column 31 by bolt.Radial limiting device 33 now can be designed to pass up and down the through hole of cantilever, during installation, first will go up a cantilever most pulls down or rotates an angle, then the quarter butt with boss 42 is inserted to the through hole of cantilever from top to bottom, connect again afterwards other quarter butt, finally will go up a cantilever adjustment most and align rear fixing.
Principle of work of the present utility model: the permission maximum concentration of establishing ore pulp in concentrated well is a, surpasses the danger that this concentration has kill-job, and allowing high density is ρ, and levitation device 5 is m with connecting rod 4 general assembly (TW)s, and levitation device 5 is v with the volume of liquid level lower link.According to buoyancy formula, we can make mg=ρ gv by swing weight-adding adjustment.When pulp density a1<a, pulp density ρ 1< ρ, mg> ρ 1gv, gravity is greater than buoyancy, and now levitation device 5 is suspended in ore pulp by connecting rod 4; When pulp density a2>a, pulp density ρ 2> ρ, mg< ρ 2gv, gravity is less than buoyancy, and now levitation device 5 drivening rods 4 move upward, and connecting rod 4 top pressing contactors 7 are also reported to the police.
As shown in Figure 1, stationary installation 3 is fixed on security guardrail 2 along with dolly gear frame 1 is done uniform speed slow motion.When pulp density is less than permission maximum concentration, gravity is greater than buoyancy, and levitation device 5 is suspended on the cantilever that is provided with radial limiting device 33 by stock 41 and boss 42; When pulp density is greater than while allowing maximum concentration, gravity is less than buoyancy, and levitation device 5 drives stocks 41 to move up until the top pressing contactor 7 of stock 41, and now alarm 6 is reported to the police.
