Abstract

The utility model discloses a stifled cleaning device is prevented to pelletizing roller screen, including the power device of pelletizing roller screen discharge end, this power device includes motor and reduction gear, and reduction gear power output shaft is parallel with the roller screen plane and perpendicular with the roller. The reducer power output shaft is connected with the shaft of the anti-blocking cleaner, so that the shaft of the anti-blocking cleaner is parallel to the plane of the roller screen and perpendicular to the roller shaft, the cleaning rods are vertically fixed on the anti-blocking cleaner shaft in a spiral array equidistance, and the distance between the adjacent cleaning rods along the axial direction of the cleaner is the same as that between the rollers of the roller screen, so that each cleaning rod can pass through the gap of the roller screen. The anti-blocking cleaner can clean the clearance of the roller screen to prevent blockage. The device is safe and reliable, simple and easy to operate, does not need manual cleaning, greatly reduces the labor intensity of workers, and reduces the occurrence of safety accidents.

Description

Blockage-preventing cleaning device for pellet roller screen

Technical Field

The utility model belongs to the metallurgical equipment field relates to a stifled cleaning device is prevented to pellet roller sieve.

Background

In the production process of pellet ore, a pellet roller screen is a key device in the pellet screening process. The green pellets discharged from the pelletizing disc often contain a lot of large sticky materials and pellets with larger particle sizes are screened out by using a roller screen with the clearance larger than 16mm, but the large-particle-size materials often stay on the roller screen to block the clearance of the roller screen, so that a large amount of qualified green pellets cannot be screened out and enter a material returning system, the screening efficiency of the pellet roller screen is seriously influenced, and the production capacity of equipment is wasted. Therefore, the roller screen needs to be cleaned manually, the manual cleaning efficiency is low, and safety accidents are easily caused when the roller screen is cleaned manually in the running process. If the machine is stopped for cleaning, the waste of the equipment capacity can be caused. Therefore, it is necessary to design a device for mechanically cleaning the pellet roller screen with high efficiency.

Disclosure of Invention

An object of the utility model is to provide a stifled cleaning device is prevented to pellet roller sieve can clear up the bold material on the roller sieve automatically, does not need the workman to operate.

The purpose of the utility model is realized like this: a blockage-preventing cleaning device for a pellet roller screen comprises a power module 3, a speed reducer 2, a rotating shaft 4 and a cleaning rod 5; the power module 3 power output shaft is connected with the speed reducer 2 power input shaft, the speed reducer 2 power output shaft is connected with the rotating shaft 4, the rotating shaft 4 is fixed with the cleaning rod 5, the axis of the rotating shaft 4 is parallel to the plane of the pellet roller screen 1, is positioned in the middle of the pellet roller screen, and keeps a certain distance with the plane of the roller screen.

Further: the power module is internally provided with a motor.

Further: the cleaning rods 5 are vertically fixed on the rotating shaft 4, the number of the cleaning rods 5 is the same as that of gaps of the pellet roller screen 1, and the distance between every two adjacent cleaning rods is equal to that between every two adjacent roller screen shafts.

Further: the length of the cleaning rod 5 can ensure that the cleaning rod 5 cleans the whole roller screen, and the thickness of the cleaning rod is smaller than the gap of the roller screen.

Further: the cleaning rod is made of a rigid metal material.

The utility model has the advantages that: the utility model discloses during operation, power device drive the pivot and rotate, and the clearance pole of changeing epaxial clearance one by one through the roll screen is dialled the bold material of the jam in the clearance and is fallen to the sky of pelletizing roll screen one side. The device safe and reliable, it is easy and simple to handle, do not need workman's use tool operation, greatly reduced staff's intensity of labour, furthest has avoided the emergence of incident. And simultaneously, use the utility model discloses clear up the operation, greatly improved the effect and the efficiency of clearance, practiced thrift the time.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides a pellet roll screen anti-blocking device, as shown in fig. 1 and fig. 2, the power module 3 of pellet roll screen 1 discharge end adopts the motor, and the motor output shaft is connected with reduction gear 2, and the output shaft and the pivot 4 of reduction gear 2 are connected, and clean pole 5 is the vertical welding of spiral array on pivot 4, and pivot 4 is the cylinder axle of diameter 8 cm. The axis of the rotating shaft 4 is parallel to the plane of the pellet roller screen 1, is positioned in the middle of the pellet roller screen 1, and keeps a certain distance from the plane of the roller screen. The number of the cleaning rods 5 is the same as the number of the gaps of the pellet roller screen 1, the distance between the adjacent cleaning rods is equal to the distance between the adjacent roller screen shafts, and the thickness of the cleaning rods 5 is smaller than the gaps of the roller screen.

The motor 3 is started, the motor 3 outputs power, the speed is reduced by the speed reducer 2, the rotating shaft 4 is driven to rotate at 10r/min, the cleaning rod 5 welded on the rotating shaft 4 sequentially passes through the roller screen gap, and large blocks of blocking materials in the cleaning rod are pulled to one side of the pellet roller screen.

The utility model discloses during operation, clearance pole can be one by one through the clearance of roll screen, dials the bold jam in the clearance and falls to pelletizing roll screen one side. The device safe and reliable, it is easy and simple to handle, do not need workman's use tool operation, greatly reduced staff's intensity of labour, furthest has avoided the emergence of incident. And simultaneously, use the utility model discloses clear up the operation, greatly improved the effect and the efficiency of clearance, practiced thrift the time.
