Description

Technical Field

[0001] This utility model belongs to the field of iron and steel sinter production technology, specifically relating to a system for cleaning the silo walls of a sintering mixture. Background Technology

[0002] A shuttle fabric distributor comprises a carriage, a belt conveyor, and a drive unit. The carriage, typically consisting of a frame, wheels, and other components, forms the basic structure supporting and enabling reciprocating motion. The wheels work with the rails to allow the carriage to move back and forth on the rails. The belt conveyor, mounted on the carriage, transports materials and includes components such as drive rollers, idler rollers, idlers, and the conveyor belt. The drive rollers drive the conveyor belt to transfer materials, the idler rollers change the direction of the conveyor belt, and the idlers support the conveyor belt and the materials. The drive unit includes a motor, a reducer, and a coupling, providing power for the reciprocating motion of the shuttle fabric distributor and the operation of the belt conveyor. The motor's forward and reverse rotation controls the carriage's reciprocating movement, while the reducer lowers the motor speed and increases the output torque to meet the operational requirements of the carriage and the belt conveyor.

[0003] The hematite in the sintering mixture has a high viscosity, and the addition of a certain proportion of quicklime further increases this viscosity. After mixing and pelletizing with water, the sintering mixture is transported to a shuttle distributor and then evenly distributed into the sintering mixture silo. After being placed in the silo, the mixture remains there for a period of time, easily adhering to and solidifying against the silo walls, forming a sticky material. This sticky material continuously spreads into the silo walls and must be cleaned regularly; otherwise, it will seriously affect normal production.

[0004] The sintering mixture temperature is generally between 55-65℃, and the silo depth is generally over 5 meters. When cleaning the adhering material, operators need to stand on ladders outside the silo and use pneumatic picks or jackhammers to clean it. This not only results in a harsh working environment and extremely high safety risks, but also high labor intensity and extremely low work efficiency. In addition, cleaning the adhering material often takes up normal production time. Utility Model Content

[0005] The purpose of this invention is to provide a system for cleaning the adhering material on the walls of a sintering mixture silo, in order to solve the problems of difficulty, low efficiency, high intensity, and high risk in cleaning the adhering material on the walls of a sintering mixture silo.

[0006] This utility model adopts the following technical solution: a system for cleaning the adhering material on the wall of a sintering mixture silo, comprising:

[0007] The carrying trolley is located above the sintering mixture bin, and its bottom moves on the track of the shuttle distributor via rollers; the bin is located below the shuttle distributor.

[0008] The electric hoist is fixed to the top of the carrying trolley by a fixing bracket;

[0009] The manned hoist is fixedly connected to the electric hoist by a connecting rope. It is used for workers to stand inside. The manned hoist is used to move vertically in the hopper under the drive of the electric hoist. It is also used to move horizontally along the track with the carrying trolley, so that the workers in the manned hoist can go down into the hopper to clean the materials adhering to the hopper wall.

[0010] The carrying trolley is used to move along the track of the shuttle distributor to the end of the track after the material adhering to the bin wall has been cleaned, so that the shuttle distributor can distribute the material and clean it again when material adhering to the bin wall appears.

[0011] Furthermore, the manned suspended basket is a frame with an open top. The frame consists of a left railing, a right railing, a front railing, a rear railing, and a bottom railing. The left and right railings run in the same direction as the shuttle fabric feeder's track. Guide rods are fixedly connected to the left and right railings respectively. The two guide rods are set vertically, and a pulling rope is fixedly connected to the upper end of the guide rods.

[0012] The bottom of the manned suspended platform is hinged with two symmetrically arranged wall support rods. The upper ends of the two wall support rods are hinged to the manned suspended platform, and their lower ends extend freely downward. The middle part of the two wall support rods is connected to the pull rope through the middle rope. The pull rope is used to pull the middle rope, thereby causing the lower ends of the two wall support rods to rotate upward and lock into the wall of the hopper, thus preventing the manned suspended platform from swaying when the workers are cleaning.

[0013] The beneficial effects of this utility model are:

[0014] This utility model improves work efficiency and reduces labor intensity by setting a carrying trolley on the track of the shuttle distributor above the sintering mixture silo and installing an electric hoist on the carrying trolley. The electric hoist lifts the personnel basket placed in the silo, and the operator can achieve vertical lifting and moving along the track of the shuttle distributor to reach the position of the silo that needs to be cleaned. Then, the operator can use a pneumatic pick or a pickaxe to clean the material adhering to the silo wall.

[0015] This invention features wall support rods at the bottom of a manned suspended basket. By pulling the traction rope, the lower ends of the two wall support rods rotate upward and lock onto the wall of the hopper, thus preventing the manned suspended basket from swaying during cleaning and improving work efficiency and safety.

[0016] This invention can significantly reduce the impact on the material distribution of the shuttle feeder. After cleaning the material adhering to the hopper wall, the carrying trolley is directly pushed along the track of the shuttle feeder to the end of the track, which facilitates the material distribution of the shuttle feeder. The shuttle feeder can then be started to distribute the material. If material adhering to the hopper wall appears again, it can be cleaned again. Attached Figure Description

[0022] This invention provides a system for cleaning the walls of a silo containing sintered mixtures, such as... Figure 1 and 2 As shown, it includes: a carrying trolley 1, an electric hoist 3, and a manned basket 4.

[0023] The carrying trolley 1 is located above the sintering mixture bin 5, and the bottom of the carrying trolley 1 travels on the track 2 of the shuttle feeder via rollers; the bin 5 is located below the shuttle feeder.

[0024] The electric hoist 3 is fixed to the top of the carrying trolley 1 by a fixing frame.

[0025] The personnel basket 4 is fixedly connected to the electric hoist 3 via the connecting rope 9. The personnel basket 4 is used for workers to stand inside. The personnel basket 4 is used to move vertically inside the hopper 5 under the drive of the electric hoist 3. The personnel basket 4 is also used to move horizontally along the track 2 with the carrying trolley 1, so that the workers inside the personnel basket 4 can go down into the hopper 5 to clean the materials adhering to the hopper wall of the hopper 5.

[0026] The carrying trolley 1 is used to move along the track 2 of the shuttle distributor to the end of the track 2 after the material adhering to the bin wall of the bin 5 has been cleaned, so that the shuttle distributor can distribute the material and clean it again when material adhering to the bin wall appears.

[0027] The manned basket 4 is a frame with an open top. The frame consists of a left railing, a right railing, a front railing, a rear railing, and a bottom railing. The left and right railings are aligned with the track 2 of the shuttle fabric feeder. Guide rods 8 are fixedly connected to the left and right railings respectively. The two guide rods 8 are set vertically, and a pulling rope 7 is fixedly connected to the upper end of the guide rods 8.

[0028] The bottom of the manned suspended basket 4 is hinged with two symmetrically arranged wall support rods 6. The upper ends of the two wall support rods 6 are hinged to the manned suspended basket 4, and their lower ends extend freely downward. The middle part of the two wall support rods 6 is connected to the pull rope 7 through the middle rope. The pull rope 7 is used to pull the middle rope, thereby causing the lower ends of the two wall support rods 6 to rotate upward and lock onto the wall of the hopper 5, thus preventing the manned suspended basket 4 from shaking when the workers are cleaning.

[0029] The method of using this utility model is as follows:

[0030] First, based on the condition of the material adhering to the silo wall, the carrying trolley 1 is manually pushed along the shuttle feeder track 2 to move to a position above the area where the material needs to be cleaned. Then, the worker enters the personnel basket 4 and drives the electric hoist 3 to move the personnel basket 4 vertically closer to the silo wall where the material needs to be cleaned. Finally, the pulling rope is pulled, causing the lower ends of the two wall support rods 6 to rotate upwards and lock onto the silo wall of the silo 5. Once the personnel basket 4 is stable, the cleaning can begin.

[0031] After cleaning is completed, once the staff exits the manned basket 4, there is no need to disassemble this utility model. They can directly push the carrying trolley 1 along the track of the shuttle fabric spreader to the end of the track 2, and then start the shuttle fabric spreader to begin spreading the material.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
