Abstract
The utility model relates to a resistance force grid. One side of a grid body is provided with a plurality of concave collecting grooves, and cooling air passages are arranged on the two side walls of the inner part of each collecting groove. The utility model has the advantages that the cooling air passages adopt labyrinth gap types and the collecting grooves adopt special structures, which prevents granule clinkers from directly leaking below the grid has strong resistance, which reduces effect that the resistance of charge banks is nonuniform, and causes cooling wind to be distributed uniformly. Therefore, the utility model is favorable to cool the clinkers generally and uniformly. The collecting grooves play the functions of protection and antifriction to the working surface of the grid, and the service life of the grid can be extended. The grid can not be fallen down because of reliable connection. The utility model has the advantage of convenient operation and maintenance.
Description
The utility model belongs to the cooling apparatus parts of the hot grog of cement, particularly a kind of resistance force grid.
Present existing grate cooler is the cooling apparatus of the hot grog in cement mill, and it requires to have high cooling efficiency, high heat recovery rate and high operation factor.Old-fashioned cooling machine is difficult to overcome a problem of material loading layer resistance inequality of combing owing to adopt the common grate plate that simple ventilation hole is arranged and use the air compartment air feed, causes the cooling air skewness, and cooling performance is poor, and the bed of combing is overheated, undesirable conditions such as failure rate height.
The purpose of this utility model provides a kind of resistance force grid, overcomes above-mentioned shortcoming and defect.
The purpose of this utility model is achieved in that
A kind of resistance force grid is characterized in that: resistance force grid is a whole tray type structure, and the side above the grate plate body is arranged with a plurality of spill material collecting tanks, on the two side in the spill material collecting tank cooling air channel is arranged.Its cooling air channel is a horizontal labyrinth clearance type cooling air channel.In its spill material collecting tank the dividing plate that is lower than groove depth is arranged.
Under the grate plate body locating structure is arranged--riser, and the flange of being with the joint bolt hole is arranged.
The function of the utility model resistance force grid has following characteristics and advantage:
1, adopts labyrinth clearance type cooling air channel and special construction material collecting tank, prevent that the particulate grog from directly draining to the bed below of combing, the low material performance of leaking is promptly arranged.
Though 2 can guarantee still that with the air compartment air feed most cooling airs are to blow out from ducting outlet at a high speed.High wind speed makes grate plate that high-drag be arranged, and has reduced the influence of bed of material resistance inequality relatively, makes the cooling air uniform distribution, and it is comprehensive to help grog, uniformly cooling.
3, material collecting tank plays protection and anti-attrition, the work-ing life that can improve grate plate to the grate plate working face.
4, connect assurance reliably and can not fall grate plate, easy to use and maintenance.
5, monoblock casting, rational in infrastructure, great high temperature deformation resistance ability is arranged.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the resistance force grid synoptic diagram
Fig. 2 is the resistance force grid sectional view
A kind of resistance force grid is a whole tray type structure, and the side above the grate plate body 6 is arranged with a plurality of spill material collecting tanks 1, on the two side in the spill material collecting tank cooling air channel 2 is arranged.Its cooling air channel is a horizontal labyrinth clearance type cooling air channel.The dividing plate 6 that is lower than groove depth is arranged in its spill material collecting tank.Under the grate plate body locating structure is arranged--riser 4, and the flange 5 of being with joint bolt hole 3 is arranged.
This resistance force grid is that novel cooling machine adopts inflation beam technology to solve after the problem of high-temperature zone, the device of warm area problem in the solution, but it is used for warm area simplified apparatus structure, significantly reduces cost; Adopted this new technology resistance force grid (resistance grateplate), though it still supplies cooling air with air compartment, have high-drag, low characteristics of leaking material but grate plate has special ventilation duct, thereby overcome the shortcoming of old-fashioned common grate plate, warm area in the bed that is specially adapted to comb.Efficient low-loss effect is arranged equally.
This resistance force grid name TC resistance force grid, the TC resistance force grid is the monoblock casting tray type structure, and horizontal labyrinth clearance type cooling air channel and vertical special construction material collecting tank are arranged.The combination comb bed apparatus that is used for cement clinker grate cooler TC type.It is connected with comb board roof beam with joint bolt with the special construction location, becomes the important component part of warm area in the combination comb bed.Use the air compartment air feed, hot grog is efficiently cooled off.
