Description

Technical Field

[0001] The utility model relates to the technical field of grate coolers, in particular to a blanking valve for a grate cooler. Background Technique

[0002] The grate cooler is a key device in the clinker burning system of a cement plant. Its main functions are to cool and convey cement clinker, and to provide hot air for the rotary kiln and decomposition furnace, etc., to realize the recovery and utilization of heat energy. The existing grate coolers usually use an arc valve as the blanking valve. The arc valve adopts a closed structure, the valve body is in a square structure, and the valve plate is a semi-circular steel plate. This design helps to ensure the stable flow of materials during transportation, while reducing the flying of dust and keeping the working environment clean.

A connecting plate is installed on the outer wall of one end of the vibration rod. Thrust rods distributed in a rectangular array are installed on the outer wall of the connecting plate.

[0006] When using the blanking valve for a grate cooler in this technical solution, the material flows inside the discharging pipe, and the power structure adjusts the use position of the valve plate to ensure that the material is discharged under control inside the discharging pipe. The electric push rod drives the support plate and the connecting plate to move, so that the thrust rods penetrate through the through holes and enter the inside of the discharging pipe. The thrust rods can lift the agglomerated materials inside the discharging pipe, and the vibration motor drives the thrust rods to vibrate, so as to break the materials with the thrust rods.

[0007] Preferably, flanges are installed on both the upper and lower outer walls of the housing, and fixing holes distributed in a rectangular array are opened inside the flanges. The housing is connected to an external pipeline through the flanges.

[0008] Preferably, the valve plate is designed in a circular arc shape and is in contact with the outer wall of the lower end of the discharge pipe. A power structure is provided on the outer wall of one end of the valve plate passing through the housing. The valve plate shields the outer wall of the lower end of the discharge pipe to ensure that the material is discharged through the discharge pipe under control, and the power structure drives the valve plate to rotate circumferentially.

[0009] Preferably, a fixing block is installed on the outer wall of the electric push rod, and the fixing block is connected to the inner wall of the housing. The electric push rod is fixed by the fixing block.

[0010] Preferably, a sealing ring is fixedly attached to the inner wall of the through hole, and the inner wall of the sealing ring is in contact with the outer wall of the ejector rod. The sealing ring ensures the position stability of the ejector rod inside the through hole, and the ejector rod can penetrate the through hole and enter the discharge pipe to break up the agglomerated material.

[0011] Preferably, a spring is provided on the outer wall of the vibrating rod, and the connecting plate is elastically connected to the support plate through the spring. The spring and the vibrating rod ensure the vibration position stability of the connecting plate outside the support plate.

[0012] Preferably, a vibration motor is provided on the outer wall of the connecting plate, and the vibration motor is not in contact with the support plate. The vibration motor drives the connecting plate to vibrate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the electric push rod, the vibration motor and the ejector rod, the present utility model achieves the effect of breaking up the material. The material flows inside the discharge pipe, and the power structure adjusts the use position of the valve plate to ensure that the material is discharged through the discharge pipe under control. The electric push rod drives the support plate and the connecting plate to move, so that the ejector rod penetrates the through hole and enters the discharge pipe. The ejector rod can lift the agglomerated material inside the discharge pipe, and the vibration motor drives the ejector rod to vibrate, thereby breaking up the material by the ejector rod, avoiding blockage of the discharge pipe caused by agglomerated material, and ensuring the smoothness of discharging.
