Background
The problem that the cement grinding mill grate plate is subjected to missed forging is the most common and difficult to be cured for each company, the mill grate plate is subjected to missed forging to cause loss of a grinding body and reduce grinding efficiency of the mill, on the other hand, chute blockage is caused due to missed forging, and most importantly, the problems that the blockage of a stirring machine is caused when steel is forged and mixed into cement and the blockage is blocked seriously affect the use effect of the cement. At present, a common mode of missing forging of the grinding grate plate is to fill the gap with reinforcing steel bars aiming at the gap of the grinding grate plate.
The utility model discloses a cement powder grinding grate plate as disclosed in the patent application with the application number of CN202020315519.X, the utility model discloses a cement powder grinding grate plate, which is a grate plate combined by a plurality of fan-shaped grate plate monomers, a guard plate is arranged outside each grate plate monomer, each grate plate monomer is a stainless steel plate with the thickness of 3-8 mm, grate slits are fully distributed on each grate plate monomer, two sides in the middle of each grate slit are symmetrically provided with outwards convex circular arcs, a plurality of spurs are arranged in each circular arc, and each grate plate monomer is composed of an upper sub-grate plate and a lower sub-grate plate; a plurality of square through holes are uniformly distributed on the guard plate, the guard plate comprises an upper guard plate and a lower guard plate which correspond to the upper and lower sub-grid plates, and the lower part of the lower guard plate is provided with a clamping groove which is matched with the upper clamping block of the wind shield. The invention has reasonable structure, has the characteristics of ventilation, large material passing area, strong rigidity, smoothness and difficult blockage, effectively improves the blockage problem of the original grate plate, improves the ventilation capability and the material passing capability of the mill, and reduces the temperature of cement. The guard plate can simultaneously protect the bolt and the grate plate. The later-period local maintenance and repair are facilitated, and the workload is reduced. The utility model discloses a through the increase punishment in advance area, improved the ventilation ability and the punishment in advance ability of mill, nevertheless not solved and leaked and forge and lead to the dead problem of mixer putty card.
Disclosure of Invention
The invention aims to solve the following problems: the large clearance of the grate plate caused by manufacturing or installation can cause the risk of forging leakage; in the past, the problem of repeated forging leakage caused by the fact that the reinforcing steel bar falls off due to stress or abrasion after the reinforcing steel bar runs for a period of time after gap filling is carried out.
The purpose of the invention is realized by the following technical modes: a grinding grate plate anti-forging structure comprises a grate plate main body, grate plate discharge holes, a grate plate backup plate and a grate plate edge support; the grate plate main body and the grate plate discharging holes form a grinding grate plate main body, the grinding grate plate is integrally a casting part, and each grate plate discharging hole is provided with a plurality of holes so that cement can be discharged under the action of gravity; the edge support of each grid plate is connected with a grid plate backup plate.
Optionally, the size of the grate plate backing plate is 10mm in thickness and 70mm in width, and the radian is consistent with that of the grate plate main body.
Specifically, a grate plate backup plate is connected to the back of each grate plate edge support and the grate plate edge support of the other grinding grate plate, and the grate plate backup plates are connected firmly through welding.
Specifically, the grate plate discharge hole and the grate plate edge support are both positioned on the same plane, and the grate plate backup plate is positioned below the grate plate edge support.
Specifically, the main body of the grate plate is made of cast iron.
The invention has the beneficial effects that: 1. the edge supports of the grate plates are provided with clamping grooves to enable the grate plates to be tightly connected, and when the clamping grooves are abraded, the grate plate supports welded below the clamping grooves prevent the grate plates from being forged in a leakage mode due to sliding. 2. The grate plate backup plate is arranged behind the grate plate main body and is welded and connected, so that the grate plate backup plate is reliable and cannot fall off due to abrasion and impact, the problem of repeated forging leakage caused by falling off due to stress or abrasion of the steel bars after the grate plate backup plate operates for a period of time is solved permanently. 3. The existing grinding grate plate support is used for transformation, a grate plate backup plate is arranged behind the lapping joint of the edge of the grate plate and the edge of the other grate plate, when a gap exists between the grate plates, steel forging cannot leak because the grate plate backup plate is arranged behind the grate plate backup plate to be used as a barrier, and the risk of forging leakage caused by large gap of the grinding grate plate due to casting or installation is reduced.
