Cement grinding mill discharging grid plate

Abstract

The invention discloses a cement grinding mill discharging grid plate, and discloses a discharging grid plate which can avoid grid seam blockage by realizing reciprocating motion of grid seams throughthe reciprocating motion of main inserting plates and auxiliary inserting plates in inserting grooves and can assist in discharging. The cement grinding mill discharging grid plate is characterized in that a supporting frame is formed by connecting a large circular ring and a small circular ring through connecting rods; the large circular ring and the small circular ring are concentric; a slidingpost is arranged at the bottom of each connecting rod; at least three main grid plates are placed on the supporting frame at an equal angle; the main grid plates are positioned between adjacent two connecting rods; the main grid plates are fan-shaped plates; fixing lugs are respectively arranged on the two sides of each main grid plate; the fixing lugs are placed on the connecting rods and are fixed through locking nuts; at least one group of grid seams are formed in the main grid plates; the grid seams are long waist seams; one end of each of the four main inserting plates is connected withthe inner walls of the grid seams at an equal angle; the other end of each of the main inserting plates extends downward; the inserting grooves are formed between adjacent two main inserting plates; and at least three auxiliary grid plates are placed on the supporting frame at an equal angle.

Description

technical field [0001] The invention relates to a cement mill discharging grate plate, which relates to a grate plate for discharging material after crushing materials on the cement mill, and belongs to the field of cement production equipment. In particular, it relates to a discharge grate plate which realizes the reciprocating movement of the grate seam through the reciprocating movement of the main insert plate and the auxiliary insert plate in the slot to avoid blockage of the grate seam and can assist in discharging. Background technique [0002] The cement mill is the key equipment for crushing the material after it is crushed, and the discharge grate is a discharge device for the rotating part of the mill. The gap is small, and there are coarse particles and grinding balls or fragments in the cement mill, which makes the discharge grate easily blocked, resulting in difficult discharge, full grinding, ball paste, etc., which seriously affects the output and production ...

Problems solved by technology

[0002] The cement mill is the key equipment for crushing the material after it is crushed, and the discharge grate is a discharge device for the rotating part of the mill. The gap is small, and there are coarse particles and grinding balls or fragments in the cement mill, which makes the discharge grate easily blocked, resulting in difficult discharge, full grinding, ball paste, etc., which seriously affects the output and production effect of the cement mill. In the existing device, vibration is used to reduce the blockage of the discharge grate plate, but because it applies the overall vibration, the force of the vibration force transmitted to the grate seam is relatively small, resulting in a low anti-blocking effect and still There is a phenomenon that the grate seam or the grate hole is blocked

[0003] Notification number CN210304065U discloses a kind of cement mill discharging grate plate, comprises the first grate plate, the 3rd grate plate and the second grate plate, all offer chute in the first grate plate and the second grate plate, and the second grate plate The side end surfaces of the first grate plate and the second grate plate are all welded with connecting plates, the bottom end surface of the first grate plate and the top end surface of the second grate plate are all provided with grooves, and the top end surface of the third grate plate is welded There is a connecting frame, and the side end surface of the third grate plate is welded with a vibrating motor. The vibration force of the vibrating discharge grate plate is evenly distributed to each grate seam or grate hole, and the force is relatively small, and its anti-blocking ability is relatively poor.
