Description

An online dredging and conveying device for a sealed water tank of a ring cooler

technical field

The utility model relates to the field of ring cooler equipment, in particular to the field of ring cooler dredging and conveying, in particular to an on-line dredging and conveying device for a sealed water tank of a ring cooler.

Background technique

In the process of metallurgical production, the ring cooler, as an important process equipment, can effectively cool the sintered ore unloaded from the sintering machine, thereby facilitating subsequent production operations.

At present, most of the ring coolers use the sealing method of sealing water tank to seal the pressure air in the ring cooler, so as to ensure the cooling effect of the ring cooler. Due to the harsh working conditions of the ring cooler, the site environment has a lot of dust and other contaminants, resulting in the accumulation of dirt at the bottom of the sealed water tank during use, which affects the sealing effect or damages the equipment. Therefore, it is necessary to clean up the dirt in the sealed water tank in time. send out.

In the prior art, the method of cleaning and conveying the dirt in the sealed water tank is to use a hopper to extend into the sealed water tank to grab the dirt, and then transport the dirt to the outside through a screw conveying mechanism. This method requires an additional device to collect and process the conveyed dirt, which is costly and wastes manpower and material resources.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the utility model provides an on-line dredging and conveying device for a sealed water tank of a ring cooler, which can pick up the dirt from the sealed water tank and then transport it to the inside of the ring cooler trolley. Collect and dispose of the waste in a centralized manner.

The utility model is realized through the following technical solutions, and provides an on-line dredging and conveying device for a sealed water tank of a ring cooler, which comprises a screw conveyor and a hopper fixed on a column bracket of the ring cooler, and the central axis of the screw conveyor is The end is fixed with a hopper shell through the hub, the hopper shell is sleeved on the outer side of the screw conveyor shell and is provided with a dirt output port on the left side, the dirt output port is located inside the ring cooler trolley and is connected with the screw conveyor. The hopper is connected to the hopper shell and is located between the outer wall of the ring cooler trolley and the right end of the screw blade of the screw conveyor, and the upper end of the screw conveyor shell is located at the position corresponding to the hopper. There is a screw conveyor feeding port and is communicated with the hopper.

In this scheme, the hopper and the hopper shell rotate synchronously with the central shaft and the screw blades. After the hopper picks up the dirt in the sealed water tank, the dirt enters the screw conveyor from the feeding port of the screw conveyor, and the dirt is removed by the screw blades. After being transported to the dirt output port, it is discharged into the inside of the circular cooler trolley.

Preferably, two bearing seats are fixedly connected to the left and right of the base of the screw conveyor, the central shaft of the screw conveyor is axially connected to the two bearing seats, and the screw blades and the shell of the screw conveyor are located on the left bearing. outside of the seat. In this optimized solution, the screw blades of the screw conveyor, the hopper shell and the hopper adopt a cantilever structure, which can effectively overcome the problem that the device of the present invention lacks support in the sealed water tank and the trolley of the ring cooling machine. The installation and operation are carried out in the narrow space of the sealed water tank. The central shaft of the screw conveyor is axially connected with the bearing seats arranged at intervals on the left and right, so that the cantilever structure is more stable and the strength is higher.

Preferably, a sealing device is provided inside the casing of the screw conveyor between the left bearing seat and the screw blade. In this optimized solution, by setting the sealing device, it can effectively prevent dirt from entering the left bearing seat and damage the device, and prolong the service life of the device.

Preferably, several hoppers and dirt output ports are evenly spaced around the circumference. In this optimization scheme, there are several hoppers and sewage output ports evenly distributed around the circumference, which can improve the efficiency of dredging and conveying of sewage.

The beneficial effects of the utility model are as follows: through the dirt output port located inside the trolley of the annular cooling machine, the screw conveyor discharges the dirt picked up by the hopper into the trolley of the annular cooling machine, and the trolley of the annular cooling machine is used for centralized collection and processing. Therefore, additional devices or equipment are no longer required to collect and process the dirt, which reduces the cost and avoids the waste of manpower and material resources; the spiral blades, the hopper and the hopper shell are all arranged on the cantilever structure, which effectively overcomes the problem of the device of the present invention. The problem of lack of support in the sealed water tank and the trolley of the annular cooling machine, at the same time, it is more convenient for the device of the present invention to be installed and operated in the narrow space of the sealed water tank; the sealing device arranged inside the shell of the screw conveyor effectively prolongs the use of the device life.
