Multistage jigging machine embodiment:
The present embodiment uses the embodiment one of above-mentioned multistage jigging machine bellows to be described in detail with multistage jigging machine, and as illustrated in figures 3-6, a jigging cycle of multistage jigging machine is in chronological sequence divided into charging period, the phase of expansion, exhaust cycle and stand-down.Multistage jigging machine is divided into two points of selections from feeding end to discharge end direction, is respectively first point of selections and second point of selections.Multistage jigging machine comprises the jigging chamber 30 being loaded with water, is provided with sieve plate in jigging chamber 30, and raw coal carries out screening operation on sieve plate.The sieve plate of multistage jigging machine, jigging chamber 30, feeding and discharging system, control system and other accessory systems are prior art, are not repeated at this.One section of distribution plenum 23 and two sections of distribution plenums 19 are respectively first point of selections and second point of selections air feed of multistage jigging machine, namely the outlet air end of one section of one Room aid distributing pipe 25 and one section of two Room aid distributing pipe 24 reaches in the water below the interior first point of selections of jigging chamber 30, one section of one Room aid distributing pipe 25 and two section of two Room aid distributing pipe 24 are all provided with stop valve 28, and outlet air end place is all provided with floating ball valve 29.Floating ball valve 29 can prevent the water in jigging chamber 30 from entering into aid distributing pipe.As can be seen here, distribution plenum and one_to_one corresponding air feed identical with the sorting hop count amount of jigging machine.
Because one section of inlet air plenum 2 and two sections of inlet air plenum 18 are mutually cut off and are all provided with respective air inlet, so one section of inlet air plenum 2 can both be connected from the different air feed system for wind pressure by respective air inlet with two sections of inlet air plenum 18, namely one section of air inlet 1 connects the first air blast, two sections of air inlets 26 connect the second air blast, achieve independent manipulation or the control of each point of selections air feed, what just can regulate each point of selections as required in the work of multistage jigging machine supplies wind pressure, realizes each section and carries out jigging operation separate under wind pressure.
Introduce the course of work of multistage jigging machine below:
First in multistage jigging machine, water is added, and make it normal circulation, start up system afterwards, initial adjustment parameter, multistage jigging machine is made to enter duty, then in multistage jigging machine, raw coal is added, regulate the blast of each point of selections, the blast of each point of selections is made to be 0.01 ~ 0.04MPa, be preferably 0.02 ~ 0.03MPa, and the blast of each point of selections is different, and have marked difference, make multistage jigging machine from feeding end to discharge end direction the blast that uses of each point of selections progressively reduce, namely the wind pressure ratio of first point of selections and second point of selections is 1:(0.5 ~ 0.9).After the blast of good each point of selections to be regulated, multistage jigging machine enters normal operating conditions, carries out sorting by density.As shown in Figure 3, open first and second air blast, its blast is regulated to make it to meet the demands, open the stop valve 28 on one section of air inlet valve and two sections of air inlet valves and aid distributing pipe, air feed is carried out to first and second point of selections of multistage jigging machine, the material of water in jigging chamber 30 under the effect of blast upwardly on sieve plate is now the charging period of a jigging cycle.As shown in Figure 4, close one section of air inlet valve and two sections of air inlet valves, stop air feed, now enter the phase of expansion of a jigging cycle.As shown in Figure 5, open one section of exhaust valve and two sections of exhaust valves are exhausted, the water-band in jigging chamber 30 is moved materials downward and is fallen back on sieve plate, is now the exhaust cycle of a jigging cycle.As shown in Figure 6, close one section of exhaust valve and two sections of exhaust valves, now enter the stand-down of a jigging cycle.What first point of selections were sieved out is spoil, and what second point of selections were sieved out is middle coal, finally from discharge end out be cleaned coal.
In like manner, also can the embodiment two of multistage jigging machine bellows be used on multistage jigging machine, because one section of inlet air plenum 2 ' and two sections of inlet air plenum 18 ' are interconnected, so be only provided with air inlet 27 in one section of inlet air plenum 2 ', air inlet 27 is connected with air feed system, the blast of air feed system is met the demands, the blast in two sections of distribution plenums 19 ' is regulated afterwards again by the aperture of adjusting pressure release valve 17, and then achieve independent manipulation or the control of each point of selections air feed, what just can regulate each point of selections as required in the work of multistage jigging machine supplies wind pressure, realize each section and carry out jigging operation separate under wind pressure.
Based on same principle, multistage jigging machine bellows in the utility model can also be provided with three distribution plenums or four distribution plenums, the bellows being provided with three distribution plenums are applicable to the jigging machine with three points of selections, and the bellows being provided with four distribution plenums are applicable to the jigging machine with four points of selections.The same with the aforesaid jigging machine with two points of selections, the jigging machine with three points of selections and four points of selections be also all from feeding end to discharge end direction the blast of each point of selections progressively reduce, and the blast of each point of selections is 0.01 ~ 0.04MPa, be preferably 0.02 ~ 0.03MPa.For the jigging machine with three points of selections, the wind pressure ratio of its three points of selections is 1:(0.5 ~ 0.9): (0.4 ~ 0.8); For the jigging machine with four points of selections, the wind pressure ratio of its four points of selections is 1:(0.5 ~ 0.9): (0.4 ~ 0.8): (0.3 ~ 0.7).
Lower mask body introduces the course of work of the jigging machine with four points of selections:
In work, material enters first point of selections, because material averag density is comparatively large, needs larger shatter value, just can make coal that density difference is larger and the rapid layering of spoil, the low pressure blast that is first point of selections needs is higher.After first point of selections sorting, enter into the material bed of second point of selections, it has granularity and all less feature of density, and these coals and middle coal have obtained rough segmentation layer first point of selections, certain stratification state is also maintains second point of selections, therefore the layering of second point of selections needs to carry out further accurately layering, and excessive shatter value can upset the bed material divided on the contrary, and that is second segment needs relatively little low pressure blast to increase the chance of layering.Enter into the material bed of the 3rd point of selections, by the second segment middle coal of venting, bed is lighter, and remains front two sections of stratification states obtained, therefore the 3rd point of selections need less shatter value, and that is the 3rd point of selections need less low pressure blast relatively to stablize layering.Enter into the material bed of the 4th point of selections, the heavier gangue and middling coal by first three section of emptying, bed is the lightest, and remains the stratification state that first three section obtained, therefore needs less low pressure blast with stable layering.Make the layered effect of each point of selections of jigging machine reach optimum state like this, improve the efficiency of separation, add product recovery rate, reach the effect reducing product loss.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
