Abstract
The invention discloses a cooling device for gangue decarburization. The device includes a cylindrical shell with an air inlet at the bottom and an air outlet on the top; a lower part of the cylindrical shell is provided with at least one blanking tube with one end communicating with the cylindrical shell inside and the other end being a material inlet which is equipped with a valve; each blanking tube is provided with a spreading table therein, which has one end connected with the blanking tube and the other end extending into the cylindrical shell and is inclined to the cylindrical shell bottom. The device of invention has a simple structure and low abrasion, and can cool materials uniformly with high efficiency to save energy and reduce consumption.
Description
Technical field
The present invention relates to a kind of gangue decarburization chilling apparatus.
Background technology
Gangue is the less black barren rock of phosphorus content of discharging in the coal mining process, is the solid waste of China's discharge capacity maximum, and its discharging not only takies a large amount of arable lands with accumulation, simultaneously earth's surface, atmosphere has been caused very large pollution.The chemical composition of gangue is more similar to clay, and gangue contains higher carbon and sulphur, and loss on ignition is larger.Only in certain temperature range, could produce the suitable melt substance of sufficient amount viscosity, have expansion character.According to its feature, China has developed coal gangue haydite.
Coal gangue haydite with meet burn the swollen gangue that requires through fragmentation, preheating, burning expand, cooling, classification, packing produce.But existing cooling device for gangue decarburization, cooling air quantity is wayward, and drop temperature is too high, because gangue decarburization is finished when entering the cooler quenching by tremie pipe, material characteristic is constantly all to change, granular size and blanking are inhomogeneous, so each position material of cooler cooling-air and all not identical through bed of material resistance, and inhomogeneous cooling is even, quenching is poor, thereby strengthened the problem of the energy consumption of system, indirectly caused cooling off energy recovery and significantly reduce, do not reached the effect of energy-conserving and environment-protective.
Summary of the invention
The technical problem to be solved in the present invention is that existing cooling device for gangue decarburization cooling air quantity is wayward, and drop temperature is too high, and the inhomogeneous inhomogeneous cooling that causes of blanking is even, and quenching is poor, consumes energy high not environmental protection.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of cooling device for gangue decarburization, comprise cylindrical shell, and described cylinder body bottom is air inlet, the top is air outlet; The cylindrical shell bottom also is provided with the tremie pipe of at least one, and tremie pipe one end is communicated with inner barrel, and an end is material inlet, and described material inlet place is provided with valve; Also be provided with a spreading platform in each tremie pipe, spreading platform one end connects tremie pipe, and an end stretches in the cylindrical shell, and described spreading platform is obliquely installed to cylinder body bottom.
The setting of spreading platform, material when making spreading can fully spread out, thereby increased the contact area of material and cooling blast, be more conducive to material and reach the optimization distribution, cooling is even, thereby reaches the purpose that quenching is good, heat recovery efficiency is high, in addition, the material cooling evenly also is convenient to cooling air quantity and is kept constant.The setting of valve can prevent cooling air in the cooler in the cooling material, from tremie pipe ' race ' fall normally blanking of the material in the tremie pipe that makes.
As a kind of improvement project of the present invention, the upper surface of spreading platform becomes 25 °-40 ° with horizontal plane.
Be the service life of extension fixture, described valve adopts flap valve.Valve plate automatically springed open when flap valve weighed constant weight according to the material of the blanking of tremie pipe, so that material passes through.The flap valve that adopts in this device is existing apparatus, compares with common valve, and the wear intensity of its use is little, and service time is long.
For making the blanking of this device more even, described tremie pipe has two, and is symmetricly set on the cylinder body outer wall.
Cooling air quantity for ease of in the control cylindrical shell also is provided with temperature measuring equipment and pressure tester on the cylindrical shell.By the setting of temperature measuring equipment, pressure tester, temperature, the pressure that can control more accurately in the cylindrical shell reach desired value, and described temperature measuring equipment, pressure tester adopt existing temperature sensor and pressure sensor.
For making things convenient for the carrying out of service work, also be provided with access door on the cylindrical shell.
For the service life of protection cylindrical shell, the maintenance capacity that reduces wear, reduces equipment, increase equipment, also post one deck liner plate on the cylinder inboard wall.
Advantage of the present invention is: simple in structure, low, the material of wearing and tearing cooling evenly, cooling effectiveness is high, energy-saving and cost-reducing.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1-2, the present invention includes cylindrical shell 1, liner plate 2 and two tremie pipes 4, liner plate 2 is fitted with cylindrical shell 1 inwall; Two tremie pipes 4 are symmetricly set on cylindrical shell 1 sidewall, tremie pipe 4 one ends are material inlet, the material inlet place is provided with check-valves 4-1, the other end is communicated with cylindrical shell 1 inboard, and the junction is provided with a spreading platform 4-2, spreading platform 4-2 one end connects downward-sloping the stretching in the cylindrical shell 1 of tremie pipe 4, one ends, and the upper surface of spreading platform 4-2 becomes 35 ° with horizontal plane; Described cylindrical shell 1 top is provided with air outlet 7, and the bottom is provided with air inlet 8, also is provided with access door 3, temperature sensor 5 and pressure sensor 6 on the cylindrical shell 1.
During use, material enters in the cylindrical shell 1 from tremie pipe, and being sprinkled in the cylindrical shell 1 of fully disperseing at spreading platform 4-2 place, and cooling blast is blown into through air inlet 8, and drives from bottom to top material and blow out from air outlet 7, and in this process, material obtains evenly fully cooling; Temperature sensor 5 and pressure sensor 6 are transmitted to external control system with temperature, pressure signal, and control system is according to the cooling air quantity in these signal controlling inflow cylindrical shells 1.
