Description
Technical Field
The utility model relates to a cold quick-witted part technical field of comb specifically is a modular choked flow comb board.
Background
At present, cement production lines operated at home and abroad are novel dry-process pre-decomposition production lines with large scale from 1500T/D to 12000T/D. The grate cooler is a key device in the production of the cement industry, and the pressure of the cement industry as the industry with high energy consumption is increasing along with the continuous enhancement of domestic energy-saving and environment-friendly requirements. Higher requirements are put on the heat recovery efficiency and the equipment operation rate of the grate cooler, and the unit load of the grate cooler is higher and higher. The material layer on the movable grate bed is improved to 800-900 mm, even more than 1000 mm from the previous 400-500 mm. Because the center of the rotary kiln and the center of the grate cooler are offset and have a certain height difference, clinker falling from the rotary kiln to the grate cooler has segregation phenomenon, the distribution of the clinker on the grate bed is uneven, the middle part is high, the two sides are relatively low, and fine powder with high temperature at the upper part forms red river trickle (called red river in the industry term) at the two sides of the grate cooler. Because the red river has high flowing speed and high temperature and is difficult to cool, in order to eliminate the red river, flow blocking grate plates are additionally arranged on two sides of the grate cooler with the red river, the length of the red river is effectively shortened, the clinker on the grate bed is relatively uniform in thickness, and the cooling effect is improved.
However, the choke plate in the prior art has a simple structure, the choke plate is designed with longer mounting bolts and has poor reliability, and in order to ensure the operation rate of the grate cooler, the choke plate is mounted and welded with the front and rear grate plates by stainless steel welding rods so as to ensure the operation rate of the grate cooler in the normal production process. Because the flow-resisting grid plate and other grid plates are operated in the clinker, the flow-resisting grid plate and the movable grid plate can generate normal abrasion after operating for a period of time, so that the contact position of the side surface of the flow-resisting grid plate and the movable grid plate is abraded, and as the abrasion degree is increased, the gap is enlarged, larger clinker can enter the gap, the operation load of the grate cooler is increased, and hidden troubles are brought to the operation. The flow blocking grate plate needs to be replaced after being used for a certain period, because the flow blocking grate plate and the front and rear grate plates are welded by stainless steel welding rods, an oxygen cutting gun cannot be cut off, the angle grinder is difficult to operate and is troublesome to replace, the replacement cost of the whole flow blocking grate plate is relatively high, and most of the flow blocking grate plates are not worn, so that great waste is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a modular choked flow comb board to solve the problem that provides among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a modular choked flow comb board, includes the choked flow comb board, choked flow comb board one side fixed mounting has the side guard plate, pass through connecting bolt fixed connection between choked flow comb board and the side guard plate, and connecting bolt is equipped with the multiunit, circular comb hole has been seted up on choked flow comb board upper end surface, and circular comb hole is equipped with a plurality of, choked flow comb board lower extreme is located circular comb hole and locates fixed mounting all around to have the grudging post.
Preferably, the side guard plate is of an inverted L-shaped structure.
Preferably, the connecting bolt is of a T-shaped structure.
Preferably, the circular grid holes are uniformly distributed on the surface of the flow blocking grid plate, and the distance between every two circular grid holes is consistent.
Preferably, the circular grid holes are in a conical structure.
Preferably, a sunk pit is formed in the flow blocking grate plate.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses can play the effect of the red river of elimination of choked flow comb board.
2. The utility model discloses because through connecting bolt fixed connection between choked flow comb board and the side guard plate, it is convenient to maintain, when the side guard plate wearing and tearing need be changed, demolish the connecting bolt between side guard plate and the choked flow comb board, can get the side guard plate and change, maintain simple and convenient, efficient.
3. The utility model discloses an it has the pit to open in the choked flow comb board, can store the material, has the effect of slowing down the grog and flowing.
4. The utility model discloses because the side guard plate is the type of falling L structure, play with side-mounting's choked flow comb board do not have the direct leakage condition, reduce the grog and directly leak to the plenum in, have the effect that reduces the hourglass material.
