Description

Technical Field

[0001] The utility model relates to a ploughshare type silt clearing device for a sintering ring cooler. Background Art

[0002] The function of the sintering ring cooler is to reduce the hot sintered ore produced by the sintering machine from 750℃ to 850℃ to below 120℃ through positive pressure blast cooling, so that the sintered ore can be transported and screened after being cooled. The cooling process has high requirements for the overall sealing of the ring cooler. Excessive harmful air leakage of the ring cooler will not only cause energy waste and forced reduction of sintering production, but also affect the heat radiation and dust pollution around the ring cooler. In order to reduce the air leakage rate of the sintering ring cooler, our factory installed a water sealing device for the ring cooler. The water seal of the sintering ring cooler is an upper and lower water seal. The upper water tank consists of two relatively independent inner and outer annular grooves, and the internal water is injected to achieve the purpose of sealing the flue gas. In the actual production process, the dust precipitates in the upper water tank to form sludge. When the sludge thickness reaches 5cm, the water level rises, which will cause water to overflow around the ring cooler. If the water is not replenished in time, it may cause the water seal to fail. At present, manual methods are used to clean the sludge. When manually cleaning the sludge in the upper water tank of the annular cooler, in order not to affect the normal production of the annular cooler, the upper water tank is rotated slowly in the startup state, and a person stands in a suitable position, inserts a narrow shovel into the bottom of the upper water tank, shovels up the sludge, and pours it onto the annular cooler trolley. Not only is the working environment poor, but it is also time-consuming and labor-intensive, and the upper water tank moves in a circular direction with the annular cooler body, and the personnel cannot keep up with the rhythm, are in a hurry, and there is a risk of slipping. At the same time, rotating parts such as wheels and trolley bodies will cause mechanical injuries to operators, posing a major safety hazard. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a plowshare type silt clearing device for a sintering ring cooler, which is used to solve the problems of high labor intensity and mechanical injury accidents caused by manual cleaning of silt in the upper water tank of the water seal of the sintering ring cooler.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a plowshare type mud clearing device for a sintering ring cooler, which is composed of a plowshare, a mud guide trough, a mud discharge plate, a side plate, a plow support, and an electric hydraulic push rod. The plowshare is composed of a plow shovel and two vertical plates. The mud guide trough is made of channel steel. The plowshare is welded to one end of the mud guide trough, and it is required to keep the bottom surface of the mud guide trough and the bottom surface of the plow shovel of the plowshare on the same horizontal plane during welding; the mud discharge plate is composed of a bottom plate and two mud guards to form a U-shaped structure. The mud discharge plate is welded to the other end of the mud guide trough, and it is required to keep the angle between the bottom plate plane of the mud discharge plate and the bottom surface of the mud guide trough at 170° during welding, ensuring that the angle between the bottom surface of the plow shovel and the bottom surface of the upper water tank when the plowshare cleans the mud is 10°; the side plate is welded and fixed at a suitable position on the outside of the mud guide trough close to the plowshare, and it is required to keep the side plate plane The side plate is perpendicular to the bottom plane of the mud guide groove, and is used for supporting the device. A circular fixing hole is provided on the side plate, and is used for fixing the side plate to a bracket at a suitable position around the annular cooler by bolts; the plow support is welded and fixed to the position where the outer plane of the bottom plate of the mud unloading plate is connected to the mud guide groove, and it is required to keep the upper surface of the plow support and the outer plane of the bottom plate of the mud unloading plate on the same horizontal plane during welding; the plow support is used for supporting the device and connecting the electric hydraulic push rod, and four circular fixing holes are provided on the plow support, and are used for fixing the plow support to another bracket at a suitable position around the annular cooler by bolts; the electric hydraulic push rod is vertically installed on the bracket fixing the plow support, and a connecting sleeve is installed at its shaft end and the end is welded to a suitable position at the bottom of the plow support, and the electric hydraulic push rod is used to control the lifting and stroke positioning of the entire sludge clearing device.

[0005] When using the device, the electric hydraulic push rod is used to drive the entire device to descend, so that the plowshare contacts the bottom surface of the upper water tank. After the device is positioned, the side plate is bolted to a bracket at a suitable position around the annular cooler, and the plow support is bolted to another bracket at a suitable position around the annular cooler. By utilizing the circumferential rotation of the upper water tank of the annular cooler and the relative movement of the plowshare type silt removal device, during the operation of the upper water tank, the plowshare type silt removal device for the annular cooler does not move, and the plowshare turns up the silt deposited at the bottom of the upper water tank, and the silt is discharged into the mud discharge plate along the mud guide groove. Under the blocking effect of the mud guard, the silt outlet of the mud discharge plate is discharged onto the material surface of the annular cooler trolley.

[0006] The beneficial effects of the utility model are: the device has a simple structure, is safe and convenient to operate, and utilizes a plowshare-type sludge cleaning device to realize online and automatic cleaning of the sludge in the upper water tank without stopping the ring cooler, thereby avoiding the problems of high labor intensity and safety accidents caused by human-machine contact in manual sludge cleaning, and greatly improving the efficiency and effect of sludge cleaning.

[0014] The present invention is further described in conjunction with the embodiments.

[0015] exist Figure 1-4 In the invention, a plowshare type mud clearing device for a sintering ring cooler is provided, which is composed of a plowshare 1, a mud guide trough 2, a mud discharge plate 3, a side plate 4, a plow support 5, and an electric hydraulic push rod 6.

[0016] The plowshare 1 is made of steel plates with a thickness of δ=20mm and is composed of a plowshare and two vertical plates. The plowshare is trapezoidal, and a blade is ground at one end of its bottom to turn up the sludge in the upper water tank. The vertical plates are rectangular and welded and fixed on both sides of the plowshare to prevent the turned-up sludge from overflowing.

[0017] The mud guide groove 2 is made of channel steel, which is used to guide the mud turned up by the plowshare 1 to be discharged into the mud discharge plate 3 along the mud guide groove 2. The mud guide groove 2 is connected to the plowshare 1 by welding, and it is required to keep the bottom surface of the channel steel of the mud guide groove 2 and the bottom surface of the plowshare 1 on the same horizontal plane during welding.

[0018] The mud discharge plate 3 is welded with a steel plate with a thickness of δ=20mm, and is composed of a bottom plate and two mud guards to form a "U"-shaped structure. The bottom plate is "U"-shaped and is used to carry mud. The mud guards are similar to "L" shapes and are welded and fixed on both sides of the bottom plate to prevent the mud discharged from the mud guide trough 2 from being discharged from the mud discharge plate 3 outlet to the material surface of the ring cooler trolley.

[0019] The mud unloading plate 3 and the mud guide trough 2 are connected by welding. It is required that the angle between the bottom plate plane of the mud unloading plate 3 and the bottom surface of the channel steel of the mud guide trough 2 be maintained at 170° during welding, ensuring that the angle between the bottom surface of the plowshare 1 when cleaning the silt and the bottom surface of the upper water trough is 10°.

[0020] A rectangular side plate 4 is made of a steel plate with a thickness of δ=20mm, and the side plate 4 is welded and fixed upright at a suitable position outside the mud guide groove 2 near the plowshare 1. It is required to keep the plane of the side plate 4 perpendicular to the bottom plane of the channel steel of the mud guide groove 2 during welding. The side plate 4 is used for supporting the device, and a circular fixing hole is opened on its upper part, which is used to fix the side plate 4 to a bracket at a suitable position around the annular cooler by bolts.

[0021] A rectangular plow support 5 is made of a steel plate with a thickness of δ=20mm, and the plow support 5 is laid flat and welded to the position where the outer plane of the bottom plate of the mud unloading plate 3 is connected to the mud guide groove 2. It is required to keep the upper surface of the plow support 5 and the outer plane of the bottom plate of the mud unloading plate 3 on the same horizontal plane during welding. The plow support 5 is used to support the device and connect the electric hydraulic push rod 6. Four circular fixing holes are opened at the lower part of the plow support 5, which are used to fix the plow support 5 to another bracket at a suitable position around the annular cooler by bolts.

[0022] An electric hydraulic push rod 6 is vertically mounted on a bracket for fixing the plow support 5, a connecting sleeve is mounted on the shaft end thereof and the end is welded to a suitable position at the bottom of the plow support 5. The electric hydraulic push rod 6 is used to control the lifting and stroke positioning of the entire desilting device.

[0023] When using the device, the electric hydraulic push rod 6 is used to drive the entire device to descend, so that the plow shovel of the plowshare 1 contacts the bottom surface of the upper water tank. After the device is positioned, the side plate 4 is bolted to a bracket at a suitable position around the annular cooler, and the plow support 5 is bolted to another bracket at a suitable position around the annular cooler. Since the upper water tank rotates circumferentially with the annular cooler body, and the annular cooler plowshare type mud cleaning device does not move, the relative movement of the rotation of the annular cooler upper water tank and the plowshare type mud cleaning device is utilized. During the operation of the upper water tank, the plowshare 1 turns up the sludge deposited at the bottom of the upper water tank, and the sludge is discharged into the mud discharge plate 3 along the mud guide groove 2. Under the blocking effect of the mud guard, the sludge outlet of the mud discharge plate 3 is unloaded into the material surface of the annular cooler trolley, thereby achieving the purpose of automatically cleaning the sludge online without stopping the annular cooler.

[0024] The device has a simple structure and is easy to operate. It uses a plowshare-type sludge cleaning device to automatically clean the sludge in the upper water tank without stopping the ring cooler. This can reduce the labor intensity of workers and improve work efficiency. The water level in the upper water tank fluctuates little and the water sealing effect is maintained well.

[0025] The device utilizes the relative movement between the rotation of the upper water trough and the plowshare. The plowshare turns up the silt in the upper water trough and discharges it onto the material surface of the ring cooler trolley through the mud guide trough through the obstruction of the mud discharge plate. This avoids the dangerous action of operators forcing themselves to dig silt with a shovel, eliminates human-machine contact operations, and runs smoothly, safely and reliably.
