Abstract
The utility model relates to an automatic rake-lifting concentration with hoist device, which comprises a cell body and a bridge frame installed on the cell body. A transmission device is arranged on the center of the bridge frame, with the hoist device installed on the top end of the principal shaft of the transmission device. A mud scraping rake is installed on the bottom of the principle shaft of the transmission device. On the bridge frame beside the transmission device is provided a downspouting, while a feed port is made on the central position of the bridge frame in front of the downspouting. A current stabilizer is provided on the bridge frame under the feed port, and a sand pump is installed on bottom of the cell body. The utility model adds the hoist device comparing with traditional concentrator, which prevents ''rake oppressed'' in operation. A change speed motor in the transmission device controls the infinitely variable rotation of the mud scraping rake, which adapts to the dehydration works of different slurries. Besides, the utility model is highly automatized to save labor force and improve the effect of solid and liquid separation, and has advantages of vast scope of usage, reliability, stable operation and high efficiency.
Description
Technical field
The utility model belongs to a kind of dehydration equipment technical field, specifically a kind of automatic rake-lifting concentrator that makes variety classes slurry Separation of Solid and Liquid.
Background technology
At present, general large-scale solid-liquid separation dehydration equipment is thickener in factories such as ore dressing plant, coal preparation plant, thermal power plant, municipal sewage plant and water supply plant.The epoch that this thickener makes original employing solid-liquid subsidence style reach solid-liquid separation effect obtain changing, and the slurry solid-liquid separation efficiency improves greatly, and the solid-liquid two-phase after the separation can be reused.Each factory, the used thickener of enterprise still adopt old-fashioned concentrated, marker method for many years, though can reach concentrated effect, but because the slurry solid-liquid component ratio difference that different enterprise produced, the slurry of solid constituent large percentage is easy to generate " pressing rake " accident in concentration process, and it is also very undesirable to the control of bed material concentration, dewatering operation adaptability to different slurries is relatively poor, and automaticity is lower, overslaugh it in the application of many occasions.
Summary of the invention
The purpose of this utility model provides a kind of automatic rake-lifting concentrator that has lifting device.
The purpose of this utility model is achieved in that it comprises the pond body, the crane span structure that on the body of pond, is provided with, be provided with drive motors in the crane span structure center, chute and control cabinet in the setting of crane span structure center one side, the feed port that on the crane span structure center of chute end, is provided with, the stabilizing feed well that on the crane span structure of this feed port downside, is provided with, the sand pump that is provided with in pond body bottom, it is characterized in that: be provided with variable speed drive motor in the crane span structure center, the output shaft of this variable speed drive motor is connected with main shaft, be provided with mud scraper in the main shaft lower end, on main shaft, be set with axle sleeve, main shaft in the axle sleeve is provided with link stopper, two ends up and down in the axle sleeve inside side walls are provided with travel switch, also be set with the worm screw case on the main shaft on axle sleeve top, the main shaft of this worm screw upper box part and the link position of crane span structure are provided with the return compression spring.
The utility model shortens in order to make the clarification of water time in the slurry, and then the crane span structure of transmission device opposite side is provided with doser.
The utility model is compared the increase lifting device with old-fashioned compressor, has avoided the generation of " pressing rake " accident in the course of the work; Variable speed drive motor can be controlled the infinitely variable speeds of mud scraper and rotate, and is stronger to the dewatering operation adaptability of different slurries.Plurality of advantages such as the utility model also possesses the automation height, saves the labour, good effect of separating solid from liquid, applied widely, safe and reliable, stable, operating efficiency height.

Fig. 2 is the local amplification profile structural representation of Fig. 1;
Fig. 3 is the user mode vertical view of Fig. 1.
The specific embodiment
Shown in Fig. 1～3,7 is the pond body, 1 for being arranged on the crane span structure of Chi Tishang, be provided with chute 10 and control cabinet 8 in crane span structure center one side, be provided with to medicine-chest 6 at crane span structure center opposite side, also be provided with lubricating arrangement 9 in gantry middle portion, crane span structure center, chute end is provided with feed port, the stabilizing feed well 4 that on the crane span structure of this feed port downside, is provided with, the sand pump 11 that is provided with in pond body bottom, be provided with variable speed drive motor 2 in the crane span structure center, the output shaft of this variable speed drive motor is connected with main shaft 14, be provided with mud scraper 5 in the main shaft lower end, on main shaft, be set with axle sleeve 18, main shaft in the axle sleeve is provided with link stopper 15, be respectively arranged with travel switch 16 and travel switch 17 at the two ends up and down of axle sleeve inside side walls, also be set with worm screw case 3 on the main shaft on axle sleeve top, be provided with worm screw 12 and worm gear 13 in the worm screw case, the main shaft 14 of this worm screw upper box part is provided with return compression spring 19 with the link position of crane span structure 1.
Ore pulp flows into the stabilizing feed well 4 that is provided with on the crane span structure of feed port downside through chute 10, and is the radial pond body that pours in, and under the effect of gravitational field, the solid particle in the ore pulp sinks down at the bottom of the pond gradually, and primary water evenly rises to liquid level.Variable speed drive motor is rotated with the mud scraper 5 that suitable driving force drives the main shaft lower end, scrapes collection central row mine mouth at the bottom of the pond with being deposited on concentrated material at the bottom of the pond, discharges the pond bodies by sand pump 11; The primary water that rises to liquid level is then discharged the pond body by downflow weir, thereby finishes the overall process of the concentrating of ore pulp, discharge, clarification, overflow.When scraping the increase of mud resistance, this resistance is passed to worm screw 12 by main shaft 14, worm gear 13, the axial force of worm screw is increased, overcome the pressure of return compression spring 19 and produce axial displacement, promote, shape journey switch 17 is connected near the switch needle stand, motor is mentioned mud scraper, along with reducing of mud scraper resistance, worm screw restores under the pressure of return compression spring 19, makes motor stop to promote or the decline of counter-rotating drive mud scraper.When if the mud scraper resistance constantly increases, main shaft rises and runs into travel switch 16, and the signal that gives the alarm stops full machine, is not damaged with the protection body.
