Abstract
The invention discloses an annular-cooler non-pressure water-cooling grating beam which comprises supporting bases, screening beams and a cross beam, wherein the supporting bases, the screening beams and the cross beam are located in a kiln head cover. The annular-cooler non-pressure water-cooling grating beam further comprises a water inlet pipe and a water outlet pipe, the two ends of the cross beam are installed on the supporting bases, the cross beam and the screening beams are all hollow beams with one sealed ends, the sealed ends of the screening beams are installed on the cross beam, and the other ends of the screening beams are installed on one supporting base. The interior of each hollow beam is divided into an upper water chamber and a lower water chamber through a supporting and partitioning plate, each upper water chamber is communicated with each lower water chamber at the sealed end of each hollow beam, the open ends of the upper water chambers are communicated with the water inlet pipe, and the open ends of the lower water chambers are communicated with the water outlet pipe. According to the annular-cooler non-pressure water-cooling grating beam, frequent changes of temperature are prevented from leading to strength reduction of the hollow beams, effective cooling is achieved to maintain strength of the cross beam and the screening beams, and service life is prolonged.
Description
Technical field
The present invention relates to a kind of central cooler grid beam, particularly relate to a kind of central cooler water-cooled grid with no pressure beam, be applicable to metallurgy, chemical engineering technical field.
Background technology
Central cooler is the important Thermal Equipment in the cooling consolidation process of pelletizing on chain grate-rotary kiln production line, and its Main Function is that the acid pellet of high-temperature roasting carries out air salband and walks heat in machine.Charging place of grid beam in central cooler, be used for slowing down pelletizing falling speed, and filter the excessive high temperature pelletizing of volume to avoid that rotary trolley was caused to stroke and damage equipment, after high temperature pellet roasting, temperature can reach more than 1200 DEG C conventionally, therefore under the continuous duty of central cooler, grid beam must have wear-resisting and high-temperature stability, needs to possess certain intensity to ensure the fracture that do not bend in the time standing pelletizing impact simultaneously.
Grid beam is divided into solid and hollow, solid grid beam bulk strength is higher, wearability is good, but solid grid beam is from great, all easily there is Bending Deformation in its sieve beam and crossbeam, affect installation, and its life-span be generally about 1 year, heat radiation, wearing and tearing, life problems make it not utilize continuous production.
Hollow grid beam scheme is as in the patent of the applicant's application, Chinese patent CN102538486A discloses ventilation fixed screen device of circular cooler, its crossbeam and the even hollow beam of sieve beam, one end air intake of beam, other end air-out, carry out cooling by constantly cold air being passed into hollow beam to it, this technical scheme has solved the cooling problem of grid beam, by the cooling high temperature resistant requirement reducing grid beam, and due to be ventilate cooling, in the time that causing weld cracking because of the frequent variations of temperature, crossbeam or sieve beam still can continue to produce, to reach the effect increasing the service life.But applicant's discovery, the type of cooling life effect of ventilation is unsatisfactory, requires further improvement.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of central cooler water-cooled grid with no pressure beam, to crossbeam and sieve beam realize effective cooling maintain crossbeam and sieve beam strength, increase the service life.
Technical scheme of the present invention is such: a kind of central cooler water-cooled grid with no pressure beam, comprise the bearing that is positioned at kiln head cover, sieve beam and crossbeam, it is characterized in that: this device also comprises water inlet pipe and outlet pipe, described crossbeam two ends are arranged on bearing, described crossbeam and sieve beam are the hollow beam of one end sealing, the blind end of described sieve beam is arranged on crossbeam, the other end is arranged on bearing, the inner supported dividing plate of described hollow beam is divided into upper tank and lower header, described upper tank and lower header are communicated with at hollow beam blind end, described upper tank openend is communicated with water inlet pipe, described lower header openend is communicated with outlet pipe.
In a specific embodiment of the present invention, described outlet pipe is connected with cistern, and described cistern height is higher than sieve beam blind end height, and cistern is also provided with overflow pipe, and described overflow pipe height is lower than outlet pipe openend height in cistern.
In another specific embodiment of the present invention, described sieve beam and crossbeam are provided with at least two sieve caps.
Technical scheme provided by the present invention, cooling water passes into the upper tank of hollow beam from water inlet pipe, and fills gradually upper tank, and then cooling water enters lower header by the connectivity part of upper tank and lower header, then is discharged by outlet pipe.In continuous production process, cooling water is discharged after constantly passing into crossbeam and sieve beam, supporting clapboard in crossbeam and sieve beam is in cooling water surrounds, temperature is almost constant, avoid temperature frequent variations and caused the remitted its fury of hollow beam, maintain crossbeam and sieve beam strength so realize effective cooling, increase the service life.

Fig. 2 is structure side view of the present invention;
Fig. 3 is hollow beam structural representation.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but not as a limitation of the invention.
Refer to Fig. 1, Fig. 2, central cooler water-cooled grid with no pressure beam, comprise the bearing 2, sieve beam 3 and the crossbeam 4 that are positioned at kiln head cover 1, also comprise water inlet pipe 5 and outlet pipe 6, two sieve caps are at least housed on sieve beam 3 and crossbeam 4, this device is a water cooling grid boom device, takes away heat reach cooling effect by current.These device crossbeam 4 two ends are arranged on bearing 2, and crossbeam 4 and sieve beam 3 are the hollow beam of one end sealing, and the blind end 31 of sieve beam 3 is arranged on crossbeam 4, and 32 of the other ends are arranged on bearing 2, form an a head taller low heeling condition.The structure of hollow beam as described in Figure 3, the inner supported dividing plate 7 of hollow beam is divided into upper tank 8 and lower header 9, supporting clapboard 7 is not that hollow beam inside is isolated completely, jagged upper tank 8 and the lower header 9 of making of blind end at hollow beam is communicated with at hollow beam blind end, upper tank 8 openends 81 are communicated with water inlet pipe 5, lower header 9 openends 91 are communicated with outlet pipe 6, outlet pipe 6 is connected with cistern 10, cistern 10 height are higher than sieve beam blind end 31 height, cistern 10 is also provided with overflow pipe 11, overflow pipe 11 height are lower than interior outlet pipe openend 61 height of cistern 10.Cooling water is from the upper tank 8 of water inlet pipe 5 filling sieve beams 3 and crossbeam 4, then slowly flow into lower header 9, be expelled to cistern 10 from outlet pipe 6 again, in whole circulating cooling process, supporting clapboard 7 in the middle of crossbeam 4 and sieve beam 3 is all the time in cooling water parcel, be enough to maintain relatively-stationary low temperature, avoided temperature frequent variations, ensured the bulk strength of hollow beam beam body.
