Abstract
The utility model relates to sealing equipment in cement industry, particularly to sealing equipment of a grate cooler transmission mechanism, wherein a sealing plate is mounted on a grate cooler frame and sleeved on a transmission shaft; the sealing equipment includes a sealing box, an inner sealing plate, an outer sealing plate, a striker plate and a compressed air pipe; the sealing box is mounted on the other side of the sealing plate corresponding to the grate cooler; the striker plate is arranged on the sealing box; the inner sealing plate and the outer sealing plate are arranged on the transmission plate; the outermost part of the outer sealing plate is arranged between the end surface of the striker plate and the housing of the sealing box; a dust deposit flow pipe is arranged at the lower part of the sealing box; the inner sealing plate is arranged in the sealing box; and the outer part of the sealing plate is connected with the compressed air pipe. The utility model has the advantages that particle dust is prevented from easily intruding into the sealing device, the second sealing is inaccessible for the dust, the introduced compressed air has the function of cooling, and the sealing device is reasonable and free from maintenance; and even the combined sealing is partially damaged, the dust is prevented from being leaked outside.
Description
Technical field
The utility model relates to the water-tight equipment of cement industry, relates in particular to a kind of water-tight equipment of cooling machine transmission mechanism.
Background technology
4500T/d hydraulic driven cooling machine is in use advanced with its technology, and advantage safe and reliable to operation is extensively adopted by cement industry.But special because of equipment working condition, the defective of this type cooling machine transmission mechanism sealing is the unit's of selecting for use shortcoming of headache refractory the most respectively, because the characteristic of work, the castor downforce of cooling machine requires 4000-6000Pa, and dust content is high, and temperature is high.The rare slit of sealing device promptly has high temperature dust gas and blows out, and causes secondary environmental pollution.Because of seal box is outward the transmission device of cooling machine, seal bad regular meeting and cause hydraulic cylinder to be pulled, damage oil sealing; The dust-laden hot blast also can cause the little bearing of conveyor idler of transmission to damage; Thereby influence the stability of cooling machine operation, cause cooling machine maintenance workload big, characteristics such as maintenance cost height.And the cooling machine all is the difficult point of field management work in each cement production enterprise, and wherein leaking out and leaking material also is to administer one of difficult problem.Through discovering; Seal box is poorly sealed and cause the reason of damage following: 1. seal box housing employing bolt and cooling machine shell body are fastening, because built-in sealing plate is close to through tensioning apparatus and housing and is played sealing, frictional force can cause bolt looseness; Even local bolt occurs and cut off; Thereby cause leaking out and running down, other has the temperature height also can cause the pad coking under the seal box to be blown open, causes housing to leak out.2. along with the slit that occurs in the wearing and tearing of seal box itself and the motion process, high-pressure hot wind is brought dust into and is caused dust deposit in the seal.Lost efficacy when dust amasss the tensioning apparatus that completely lumps, sealing was also lost efficacy thereupon.Extrusion and collision takes place and causes the device distortion in built-in sealing plate and dust caking, and the material that leaks out more becomes serious.Part grog particle also blows out with hot blast.3. because the cooling machine belongs to Thermal Equipment, housing distortion is unavoidable.Particularly old equipment is out of shape seriously especially.And the seal box machining accuracy is higher, and installation requirement is also high.So when steel plate deformed in the installation site, built-in sealing plate understands and rigid friction takes place housing and extension bumps, cause the seal box life cycle short, damage fast.One cover Xinmi City joint sealing is installed sometimes just to be occurred damaging in several days leaking material.Under no outside adverse circumstances influence, can play sealing function, but adaptive capacity is poor, not easy care.
The utility model content
The purpose of the utility model is, the water-tight equipment of the strong a kind of cooling machine transmission mechanism of adaptive capacity is provided, and is tight to seal in the course of the work, can reach sealing effectiveness.
The sealing plate of the utility model is installed on the cooling machine frame; Sealing plate is enclosed within on the power transmission shaft; Water-tight equipment comprises seal box, inner sealing plate, external seal plate striker plate and compressed air hose, with respect to the opposite side of cooling machine seal box is installed at sealing plate, and power transmission shaft is provided with inner sealing plate and external seal plate; The outmost position of external seal plate is between striker plate end face and the seal box shell; The seal box bottom is provided with dust deposit stream pipe, and inner sealing plate is positioned at seal box, the outside compressed air hose that connects of sealing plate.
Seal box in the utility model is provided with striker plate.
The advantage of the utility model is: 1. granule dust is difficult for getting into sealing device, and existing low amounts of dust gets into the sealing of first road also can lead to the flow tube discharge, can not occur assembling; 2. can make inside and outside pressure balance through the compressed air that imports, dust is difficult to get into the sealing of second road, and the compressed air of importing can also play cooling effect, has effectively protected sealing device; 3. the sealing device of transforming is rationally rough, non-maintaining; 4. original sealing device is effectively protected, and serviceability rate greatly improves; 5. the local appearance of combination sealing was damaged also can guarantee that dust does not leak; 6. through after transforming, cooling machine site environment improves, and has eliminated the secondary pollution phenomenon; 7. after the equipment working environment improved, transmission mechanism was effectively protected, and operation rate significantly improves, and maintenance and maintenance cost significantly reduce.
Description of drawings
Fig. 1 is the installation diagram master apparent direction sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The sealing plate 7 of the utility model is installed on the cooling machine frame 8; Sealing plate 7 is enclosed within on the power transmission shaft 6; Water-tight equipment comprises seal box 1, inner sealing plate 2, external seal plate 3, striker plate 4 and compressed air hose 9, with respect to the opposite side of cooling machine seal box 1 is installed at sealing plate 7, and power transmission shaft 6 is provided with inner sealing plate 2 and external seal plate 3; The outmost position of external seal plate 3 is between striker plate 4 end faces and seal box 1 shell; Seal box 1 bottom is provided with dust deposit stream pipe 5, and inner sealing plate 2 is positioned at seal box 1, the sealing plate 7 outside compressed air hoses 9 that connect.
In the work, self-control seal box 1 welds in air compartment, in original sealing plate 7 installation sites and bolt are all covered on.Adopt inner sealing plate 2 and external seal plate 3, these two sealing plates form the labyrinth shape sealing.Dust deposit stream pipe 5 is installed in seal box 1 bottom, in time discharges casing endoparticle and dust.Original sealing plate 7 outsides import compressed air by compressed air hose 9, offset pressure reduction.Prevent that dust is blown into and plays cooling effect.
