Description

Technical Field

[0001] This utility model relates to the field of metallurgical sintering engineering, and in particular to an automatic cleaning device for sintering rollers. Background Technology

[0002] The sintering roller feeder is the main feeding equipment in belt sintering machine sinter production. The rotating roller skin evenly and flatly distributes the incoming material from the previous process onto the sintering trolley below. Due to the reinforcing ribs on both sides of the roller skin, material easily adheres to these ribs, forming material accumulation at the roller edges. In some cases, this accumulation can reach a volume of 70-100mm high and 200mm long. This accumulation affects the flatness of the material distribution on the sintering trolley, resulting in less material at the corresponding corners and uneven, concave material surfaces. This affects the negative pressure suction effect on the material surface during the sintering process, thus impacting the quality and yield of the sintered ore. Furthermore, the manual scraping of the accumulated material at the corners by the roller operators increases their workload and creates safety hazards. Utility Model Content

[0018] like Figure 1 As shown, according to an embodiment of the present invention, an automatic cleaning device for sintering roller 12 is provided for cleaning the sintering roller 12, comprising:

[0019] The fixing mechanism, serving as the mounting base of the device, is typically fixed to the frame or ground near the sintering roller 12, providing stable support for the entire cleaning device. The fixing mechanism includes a base 9 and a hinge seat 8, which is connected to the base 9. One end of the connecting mechanism is rotatably connected to the hinge seat 8. When the cleaning blade 6 contacts the sintering roller 12, the angle between the connecting mechanism and the horizontal plane is 45°-52°, selectable as 45°, 47°, 49°, 51°, or 52°. The hinge seat 8 includes a base side plate, a screw, and a nut. The screw is connected to the base side plate, and the nut is connected to the screw. One end of the cleaning arm 1 is connected to the nut.

[0020] Specifically, the base 9 is typically fixed to the frame or ground near the sintering roller 12 by bolts or other fasteners. Its top has a mounting surface to support the hinge seat 8. The hinge seat 8 consists of an M27*150 screw, a nut, and a base side plate, which can be welded from No. 20 steel plates. Rotating the adjusting nut on the screw allows the cleaning arm 1 to move back and forth axially along the sintering roller 12. When the cleaning blade 6 contacts the sintering roller 12, the connecting mechanism forms a certain angle with the horizontal plane. Typically, this angle is between 45° and 52°. Within this angle range, under the action of the counterweight mechanism, the center of gravity of the connecting mechanism ensures that the pressure of the cleaning blade 6 on the roller surface is evenly distributed.

[0021] The connecting mechanism is rotatably connected to the fixing mechanism at one end. The connecting mechanism includes a cleaning arm 1 and a cutter head storage bolt 4. The cutter head pin seat 2 is located on the side of the cleaning arm 1 close to the sintering roller 12, and the cutter head storage bolt 4 is located on the side of the cleaning arm 1 away from the sintering roller 12. A spare cutter head 7 is provided on the cutter head storage bolt 4.

[0022] The main body of the connecting mechanism is the cleaning arm 1, which is usually made of high-strength steel plate by welding or casting. Square steel with dimensions of 40mm*40mm and a length of 750mm is typically used. A cutter head pin seat 2 is installed on one side of the cleaning arm 1 near the sintering roller 12, and a cutter head storage bolt 4 is installed on the other side. The cutter head storage bolt 4 stores spare cutter heads 7: multiple spare cleaning cutter heads 6 can be suspended from the bolt shank for quick on-site replacement. By adjusting the number of spare cutter heads 7 on the storage bolt, the torque distribution of the cleaning arm 1 can be adjusted, assisting the counterweight mechanism in optimizing the cleaning pressure. When the cleaning cutter head 6 is severely worn, the cleaning arm 1 can be rotated to flip it up and detach it from the rotating sintering roller 12. The cutter head bolt 3 can then be quickly pulled out, and the severely worn cleaning cutter head 6 can be removed from the cutter head pin seat 2. The spare cutter head 7 stored on the cutter head storage bolt 4 can then be taken out. The spare cutter head 7 is inserted into the cutter head pin seat 2 and secured with the cutter head bolt 3. This makes replacing the cleaning head 6 similar to replacing a razor blade.

[0023] The cleaning mechanism is connected to the other end of the connecting mechanism. The cleaning mechanism is located on the side of the connecting mechanism close to the sintering roller 12. The cleaning mechanism includes a cutter pin seat 2 and a cleaning cutter 6. The cutter pin seat 2 is located at the other end of the connecting mechanism. The cleaning cutter 6 is connected to the cutter pin seat 2 by a cutter bolt 3. The cleaning cutter 6 can clean the material pile 13 on the sintering roller 12.

[0024] Specifically, the cleaning head 6 can be supported by a 14mm thick steel plate. The cleaning head 6 has 16mm openings, and there are 3 openings. The middle hole on the cleaning head 6 is used to insert the head storage bolt 4.

[0025] Specifically, the cutter head pin seat 2 can be composed of two steel plates, each 200mm*100mm in size and 10mm thick, with a 17mm parallel gap between them. Two 16mm round holes are drilled at the top for fixing the cleaning cutter head 6. The cutter head bolt 3 is M12*45mm in size. The cleaning cutter head 6 can be placed in the middle of the cutter head pin seat 2, with the holes of the cleaning cutter head 6 coinciding with those of the cutter head pin seat 2. The cleaning cutter head 6 is fixed to the cutter head pin seat 2 using the cutter head bolt 3. Spare cutter heads 7 are stacked and hung on the cutter head storage bolt 4.

[0026] A counterweight mechanism is connected to a connecting mechanism. Under the influence of gravity, the counterweight mechanism pulls the connecting mechanism, causing the cleaning mechanism to contact the surface of the sintering roller 12. The counterweight mechanism includes an adjustable counterweight scale 5 and a counterweight block 11. The adjustable counterweight scale 5 is connected to the side of the cleaning arm 1 closest to the sintering roller 12. Several grooves are provided at the upper end of the adjustable counterweight scale 5. The counterweight block 11 is hung on the grooves via a counterweight hook 10. Changing the position of the counterweight hook 10 alters the torque of the cleaning blade 6 in the cleaning chamber. The adjustable counterweight scale 5 has graduations.

[0027] The counterweight adjustable scale 5 is usually installed on the sweeping arm 1 at 2 / 3 of its length from the top of the sweeping arm 1. The counterweight adjustable scale 5 is usually connected to the sweeping arm 1 by welding. The counterweight adjustable scale 5 is usually a flat steel with serrations on the upper part, with a length of 500 mm.

[0028] The adjustable counterweight scale 5 is a vertically arranged strip plate with multiple rows of equally spaced grooves on its upper part. The grooves can be presented in a serrated form. One end of the adjustable counterweight scale 5 is fixed to the side of the cleaning arm 1 near the sintering roller 12. The counterweight blocks 11 are hung in the grooves by hooks. By changing the number of counterweight blocks 11 or the suspension position, the torque balance of the cleaning arm 1 can be adjusted.

[0029] Compared with the prior art, this utility model has the following advantages: The cleaning blade 6 of this utility model is easy to replace with a new spare after wear. In reality, the sintering production environment is extremely harsh, with dust, high temperatures, and noise. This device can complete the replacement of the cleaning blade 6 within 4-6 seconds, reducing the time operators spend working in harsh production environments. Spare blades 7 are stacked and stored on the cleaning arm 1. Since the spare blades 7 are consumable parts, this design allows for quick locating and replacement of spare cleaning blades 6 in harsh production environments. Simultaneously, the placement of spare blades 7 on the cleaning arm 1 makes the overall structure of this device more compact. The stacked spare blades 7 on the cleaning arm 1 enhance the cleaning force of the cleaning blade 6 with their weight, enabling a single component to perform multiple functions. The combined use of the adjustable counterweight 5 and the counterweight block 11 can change the cleaning force of the cleaning blade 6 on the circular roller. This can address the differences in adhesion of sintering raw materials on the edges and corners of the circular roller. This system addresses the issue of insufficient cleaning force due to excessive adhesion of sintering material at the edges and corners of the roller, or excessive cleaning force due to poor adhesion, which could damage the cleaning blades 6 and the roller skin of the sintering roller 12. Users can remove the accumulated material adhering to the edges and corners of the roller with appropriate force. The hinge seat 8 and base 9 work together; manual adjustment of the hinge seat 8 allows the automatic roller cleaning device to move left and right as needed, thus precisely positioning it at the required cleaning location.

[0030] This invention stores spare blades on a blade storage bolt during operation. The weight of the multiple spare blades on the bolt, combined with the weight of the counterweight attached to the adjustable counterweight scale and the weight of the cleaning arm, causes the cleaning blades to press against the working surface of the sintering roller. This allows the cleaning blades to scrape away the sticky, accumulated, and piled-up material on the edges and corners of the sintering roller. When the cleaning blades wear significantly, the downward pressure can be adjusted by changing the position of the counterweight.

[0031] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: This utility model has a simple structural principle and is easy to install and manufacture. It enables rapid removal of adhering, accumulated, and piled-up material from the edges and corners of the sintering roller. The counterweight can be adjusted according to the incoming material and adhering material conditions of the sintering roller to achieve the best cleaning effect. This improves the quality and yield of sintered ore, reduces the workload of operators and maintenance personnel in harsh environments, and eliminates safety hazards caused by operation and maintenance.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
