Abstract
The utility model relates to a pneumatic floating grid plate, which is connected into an integral box type structure. A concave collecting groove is arranged on a grid plate body, and one side of the inner part of the collecting groove is a labyrinth cooling air passage. The utility model has the advantages that the cooling air passage is combined with the collecting groove to cause cooling air to obtain reasonable guide; high speed jet air can be formed at an outlet; the distribution is uniform; the insufflating, the permeability and the diffusibility for charge banks are good; the heat exchange of the air and the charge is sufficient; the efficiency for cooling is high and the recovery of heat is high; the local overheating of a grid bed is avoided; the service life of the grid bed is extended; the air passage can not be blocked by that the charge is plugged; the wear of the working surface of the grid plate is small; the grid plate can be made of ordinary heat resistant steels; the cost is low; the grid plate can not be fallen down to safe; the operation and maintenance are convenient; the running rate of a grid cooler is improved.
Description
The utility model belongs to the cooling apparatus of cement clinker, particularly a kind of aerating grate plate.
Present existing grate cooler is the cooling apparatus of the hot grog in cement mill.Requirement has high cooling efficiency, high heat recovery rate and high operation factor.Old-fashioned cooling machine adopts the air compartment air feed owing to adopt the common grate plate that simple ventilation hole is arranged.This structure is difficult to overcome the bed of combing and goes up because of the bed thickness difference, the problem of windresistance inequality, thereby cause the cooling air skewness, cooling performance is poor, the local bed of combing is overheated, undesirable conditions such as failure rate height, especially with the high-temperature zone for very.
The purpose of this utility model provides a kind of aerating grate plate, overcomes above-mentioned shortcoming and defect.
The purpose of this utility model is achieved in that
A kind of aerating grate plate is characterized in that: aerating grate plate is the box structure that is connected as a single entity, and is arranged with the spill material collecting tank on the grate plate body, and the side in the material collecting tank has cooling air channel.
The spill material collecting tank of arranging on the grate plate body is the groove of V-arrangement, and the cooling air channel of a side is the labyrinth type cooling air channel in the material collecting tank.
The locating structure of rectangle riser is arranged under the grate plate body, and be useful on the fixed bolt hole.
The function of the utility model aerating grate plate has following characteristics and advantage:
1, cooling air channel goes out the interruption-forming high-speed jet, helps cooling air to being blown into, permeating and spread of the bed of material, and guarantees wind, material sufficient heat exchange, reaches efficient cooling and high heat recovery rate.
2, the special construction in grate plate air channel forms high-drag, has reduced the uneven influence of bed of material resistance relatively, helps the uniform distribution of cooling air, improves cooling efficiency and the bed local superheating of avoiding combing, and prolongs the bed life-span of combing.
3, the combination of cooling air channel and material collecting tank makes cooling air obtain reasonable direction, strengthens cooling performance, guarantees that simultaneously inner air channel can not fill in material and block, and in addition, the Rational structure of material collecting tank plays a part to reduce to wear and tear to the grate plate working face.
4, grate plate has good autorefrigeration, makes its actual work temperature be no more than 80 ℃, and this needn't can significantly reduce cost with the heat-resistance stainless steel of high price with regard to allowing to adopt common high temperature steel.
5, reasonably locate with being connected and make aerating grate plate safe and reliable, will not fall grate plate, easy to use and safeguard, long service life significantly improves the operation factor of grate cooler.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the aerating grate plate synoptic diagram
Fig. 2 is the aerating grate plate sectional view
A kind of aerating grate plate, aerating grate plate are the box structures that is connected as a single entity, and are arranged with spill material collecting tank 2 on grate plate body 5, and the side in the material collecting tank has cooling air channel 1.
The spill material collecting tank that the grate plate body is arranged above is the groove of V-arrangement, and the cooling air channel of a side is the labyrinth type cooling air channel in the material collecting tank.
The locating structure 4 of rectangle riser is arranged below the grate plate body, and be useful on fixed bolt hole 3.
This hollow grate plate is to be used in the novel cooling machine, this hollow grate plate is to adopt a kind of crucial new technology inflation beam (Air beam) device, promptly form a plurality of cooling junior units by hollow grate plate of boxlike and gastight box-shaped comb board roof beam, and according to the bed of material resistance of different zones and temperature targetedly with airduct for cooling air, thereby obtain high cooling efficiency and high heat recovery rate, solve castor bed problems of excessive heat, greatly reduced failure rate.This hollow grate plate called after TC aerating grate plate (Air grate plate), it is exactly the gordian technique core of TC inflation beam.
The TC aerating grate plate is used for the TC inflation boom device of cement clinker castor formula cooler.
The TC aerating grate plate is the monoblock casting box structure, in vertical labyrinth type cold airduct is arranged, there is clearance type outlet in the air channel and communicates with horizontal material collecting tank.It is connected with inflation comb beam with one group of standing bolt with the special construction location, and with the pipe special ventilation hot grog is efficiently cooled off and recovery of heat.
Claims (3)
1, a kind of aerating grate plate is characterized in that: aerating grate plate is the box structure that is connected as a single entity, and is arranged with the spill material collecting tank on the grate plate body, and the side in the material collecting tank has cooling air channel.
