Technical Field

The invention relates to a tailing dewatering device adopting a microporous ceramic rod, which mainly aims at the technical fields of reclamation engineering, environmental engineering, waterworks disposal, sludge disposal and the like.

Background

In the present day that land use is increasingly tense, and approval requirements of tailing pond construction projects (particularly new construction and expansion) are stricter, tailing discharge becomes the biggest factor restricting normal production and development of many mine enterprises. Therefore, it is necessary to treat the tailings so that the tailings can meet the discharge requirement. In the tailings treatment process, the tailings concentration and dehydration process is called a tailings dry discharge process. In order to solve the problem of tailing dehydration, a concentration and filter or a filter press system is commonly used, but the problems of large occupied area, large investment, high power consumption, high use cost and the like exist.

Along with the improvement of the beneficiation process, the beneficiation index is improved, so that the particle size of the tailing particles is greatly reduced, and the average particle size of the common tailing particles is below 200 meshes. Too fine particles of the tailings cause an increase in the substrate suction within the tailings, at which point the osmotic pressure of the water within the tailings is insufficient to overcome the substrate suction, making it difficult to drain the water within the tailings. At this point, the tailings naturally consolidate to make it difficult to remove the water from the pores. Therefore, a certain method or a specific device should be adopted to promote the drainage of water in the tailings. According to Darcy's lawNamely, the seepage flow Q of water passing through the porous medium in unit time is inversely proportional to the seepage path length l and is directly proportional to the water cross-sectional area F and the total head loss h. The invention designs a tailing dewatering device pair adopting microporous ceramic dielectric materials according to Darcy's law, which can increase total head loss h and reduce seepage path length l, and finally achieves the effect of promoting discharge.

The dry tailing discharging process includes multistage concentration of tailing slurry, and subsequent treatment in dewatering vibrating screen or other efficient dewatering equipment to form slag with small water content, easy precipitation and solidification and capable of being stored in certain place.

The microporous ceramic rod is a functional structural ceramic, the interior or surface of the ceramic body contains a large number of open or closed micro air holes, and the pore diameter is generally in micron or submicron level. Is a dielectric material which is only water, but air, and blocks solid particles. Has the characteristics of high porosity, high strength, stable physical and chemical properties, high filtration precision and good regeneration performance. As shown in figure 1, the left side 1 is a cylindrical medium body made of microporous ceramic materials, the lower edge of the medium body is an acute angle, and the stainless steel net cover in the middle of figure 1 is sleeved on the outer part of the medium body, so that the microporous ceramic rod on the right side 1 is formed.

The mould bag is made of large-area bag material made of polypropylene (PP) or Polyethylene (PE) and filled with tailings, and the bag is subjected to pressure drainage to form a consolidation filling body. The method mainly utilizes the water-permeable and slurry-impermeable characteristics of the geotechnical material to accelerate the consolidation of the filling material.

Standing for natural consolidation and dehydration, standing the filled membrane bag, slowly discharging pore water in tailings from pores of the membrane bag, and concentrating the liquid-plastic tailing slurry due to dehydration and finally consolidating the tailing slurry along with the passage of time.

The standing natural dehydration has higher requirement on the quality of the tailings, and in most cases, the particle size of the tailings is too small, the sludge content is large, the expected dehydration effect cannot be achieved by using the standing dehydration, and the standing natural dehydration is passive and the construction period is longer.

The thickener is used for dewatering and generally mainly comprises a thickening tank, a rake frame, a transmission device, a rake frame lifting device, a feeding device, a discharging device, a signal safety device and the like. The main characteristic of the thickener is that a certain amount of flocculant is added into the ore pulp to be concentrated, so that the ore particles in the ore pulp form flocs to accelerate the sedimentation speed of the ore pulp, and the aim of improving the concentration efficiency is achieved.

The thickener is a traditional tailing treatment device, is usually used together with a filter press or other devices, needs to occupy a larger field in the use process, and has the problems of large occupied area, large investment, high power consumption, high use cost and the like.

Based on the design, the tailing dewatering device of the microporous ceramic rod and the implementation method are provided.

5. the water is discharged from the water outlet 223 of the water pumping kettle 22 at intervals, the flow rate of the water outlet 223 is observed at the moment, when the flow rate is very little or even zero in a specified time, the pore water in the membrane bag 4 is removed to the best, at the moment, the vacuum pump 23 is closed, the hydraulic lifter 16 is started to lift the movable plate 14 to the original position, and the microporous ceramic rods 13 are also separated from the membrane bag 4 and completely enter the inner part of the main box outer cover 10 of the tailing dehydrator;

6. controlling a winch 24 to lift the main tank 1 of the tailing dehydrator to the front end of a movable arm 21, adjusting the position of a vehicle body, driving the device to another place, and repeating the steps 1 to 5 to perform dehydration operation;

7. self-cleaning function: because the dehydration in-process, micropore ceramic stick 13 can be infected with the silt in the tailing, so can drive this device to spacious department at the operation completion, at the water filling port injection pressure rivers of washing pipeline 17 (like figure 4), from washing pipeline 17 is the rotary pipeline who is covered with the small opening, and is in 32 micropore ceramic stick 13's clearance department, so, the efflux that the small opening flows can wash micropore ceramic stick 13, the sewage of washing can follow the hole outflow of bottom plate 15.

The embodiments of the present invention are disclosed as the preferred embodiments, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention and make various extensions and changes without departing from the spirit of the present invention.
