[0044] Figure 1 This is a cross-sectional view of a converter in one embodiment of the present application; Figure 2 for Figure 1 A schematic structural diagram of the cleaning device in the illustrated embodiment.

[0045] See Figure 1-2 The converter provided in one embodiment of the present application includes a furnace head 10, a furnace hood 20 and a cleaning device 30.

[0046] The furnace head 10 has an opening 11, and the furnace hood 20 is connected to the furnace head 10. A accommodating space 21 communicating with the opening 11 is provided in the furnace hood 20. The cleaning device 30 includes a cleaning component 31 provided in the accommodating space 21. The cleaning component 31 is configured to be able to rotate relative to the furnace hood 20 around a first axis a to clean the furnace hood 20.

[0047] The above-mentioned converter is provided with a cleaning assembly 31 in the furnace hood 20, and the cleaning assembly 31 can rotate relative to the furnace hood 20, so that the cleaning assembly 31 can clean the inner wall of the furnace hood 20, thereby cleaning the volatiles attached to the inner wall of the furnace hood 20, preventing the volatiles from accumulating in the furnace hood 20, thereby avoiding clogging of the furnace hood 20 and the connection between the furnace head 10 and the furnace hood 20, thereby saving the time of stopping the converter for cleaning, and improving product quality and production efficiency.

[0048] It should be understood that the cleaning assembly 31 can contact the inner wall of the furnace hood 20 , thereby cleaning the inner wall of the furnace hood 20 .

[0049] Specifically, if Figure 1 As shown, the converter also includes a feed pipe 40 extending through the furnace hood 20. One end of the feed pipe 40 extends into the furnace head 10. A feed channel 41 is provided within the feed pipe 40, allowing material to enter the furnace head 10 from outside the furnace hood 20 through the feed channel 41. Therefore, in the above embodiment, a cleaning assembly 31 is provided within the furnace hood 20 to clean volatile substances from the inner wall of the furnace hood 20, preventing clogging of the furnace hood 20 and the connection between the furnace head 10 and the furnace hood 20, thereby avoiding clogging of the feed pipe 40. This saves time in cleaning the furnace hood 20 and the feed pipe 40, thereby improving product quality and production efficiency.

[0050] Figure 3 for Figure 1 A side view of the burner in the illustrated embodiment; Figure 4 for Figure 1 Front view of the burner in the illustrated embodiment.

[0051] In some embodiments, such as Figure 3-4 As shown, the furnace head 10 is provided with a first transmission assembly 50 at the opening 11, Figure 1-2 As shown, the cleaning device 30 further includes a second transmission assembly 32 that is respectively connected to the first transmission assembly 50 and the cleaning assembly 31. The furnace head 10 is configured to rotate relative to the furnace hood 20 about a second axis b parallel to the first axis a, thereby driving the cleaning assembly 31 to rotate with the aid of the second transmission assembly 32. Thus, by providing the first transmission assembly 50 on the furnace head 10 and configuring the cleaning device 30 to include the second transmission assembly 32, when the furnace head 10 rotates relative to the furnace hood 20 about the second axis b, the first transmission assembly 50 disposed within the furnace head 10 rotates along with the furnace head 10, driving the second transmission assembly 32 connected to the first transmission assembly 50 to rotate about the second axis b, thereby driving the cleaning assembly 31 connected to the second transmission assembly 32 to rotate, thereby cleaning the inner wall of the furnace hood 20. It should be noted that during operation of the converter, the furnace head 10 rotates relative to the furnace hood 20 driven by the existing drive device. Therefore, by providing the first transmission assembly 50 and the second transmission assembly 32, the existing power for driving the burner 10 to rotate is utilized to drive the cleaning assembly 31 to rotate, without the need to provide an additional driving device for driving the cleaning assembly 31, thereby saving energy and space.

[0052] It should be noted that the first axis a is not coaxially arranged with the second axis b, so that the second transmission assembly 32 can be connected to the first transmission assembly 50 in transmission, and the second transmission assembly 32 does not occupy too much space at the opening 11 so as not to hinder the arrangement of components such as the feed pipe 40.

[0053] In some embodiments, combined Figure 1 and Figure 3-4 As shown, a retaining ring 60 is provided at the opening 11 of the burner head 10, and the first transmission assembly 50 is provided on a side of the retaining ring 60 close to the second transmission assembly 32. In this way, by providing the retaining ring 60, the material in the burner head 10 is prevented from entering the furnace cover 20, and by providing the second transmission assembly 32 connected to the retaining ring 60, the connection reliability of the second transmission assembly 32 and the burner head 10 is improved.

[0054] In some embodiments, such as Figure 3-4As shown, the first transmission assembly 50 includes a plurality of baffles 51 arranged on the burner head 10 at intervals around the second axis b. The cleaning device 30 also includes a transmission shaft 33 connected to the second transmission assembly 32 and the cleaning assembly 31 respectively (see FIG. Figure 1-2 ), the second transmission assembly 32 drives the cleaning assembly 31 to rotate by means of the transmission shaft 33. The second transmission assembly 32 includes a plurality of transmission plates 321 protruding from the side wall of the transmission shaft 33. The plurality of transmission plates 321 are arranged at intervals around the first axis a. The transmission plates 321 are constructed to be able to abut against the baffle 51 during the rotation of the baffle 51 around the second axis b, so as to be driven to rotate by the baffle 51. In this way, by providing a plurality of baffles 51 and a plurality of transmission plates 321, and during the rotation of the baffle 51, the baffle 51 can abut against the transmission plates 321, so that when the baffle 51 passes through a transmission plate 321, the baffle 51 pushes the transmission plate 321 to move, thereby driving the transmission shaft 33 connected to the transmission plate 321 to rotate, so that the transmission shaft 33 drives the cleaning assembly 31 connected thereto to rotate.

[0055] Specifically, if Figure 3-4 As shown, the baffle 51 includes a first side and a second side connected to each other. The first side of the baffle 51 is connected to the inner wall of the burner 10, and the second side of the baffle 51 is connected to the retaining ring 60, so that the baffle 51 is reliably fixed in the burner 10.

[0056] Alternatively, as Figure 2 and Figure 4 As shown, multiple baffles 51 are arranged in a circular array, and multiple transmission plates 321 are arranged in a circular array, so that during the rotation of the baffles 51, the multiple baffles 51 pass through the second transmission assembly 32 at a stable frequency, thereby continuously pushing the multiple transmission plates 321 to rotate respectively, so that the second transmission assembly 32 can rotate continuously and stably to avoid inertial rotation or reversal.

[0057] In one embodiment, Figure 4 As shown, the number of baffles 51 is 6. Figure 2 As shown, the number of the transmission plates 321 is 4. In other embodiments, the number of the baffles 51 and the transmission plates 321 can also be set in other ways according to the needs of use, which is not limited here.

[0058] Furthermore, if Figure 2As shown, a blocking portion is provided at one end of the transmission plate 321 away from the transmission shaft 33, and the blocking portion includes a first surface 3211 and a second surface 3212 arranged obliquely to the first surface 3211. Thus, by providing the obliquely arranged second surface 3212 at the end of the transmission plate 321 away from the transmission shaft 33, the baffle 51 abuts against the transmission plate 321 via the second surface 3212 during the rotation of the baffle 51, thereby pushing the transmission plate 321 to rotate, thereby preventing the side of the baffle 51 away from the burner head 10 and the end of the transmission plate 321 away from the transmission shaft 33 from abutting and colliding, which could cause damage to the components.

[0059] It should be understood that the transmission shaft 33 is arranged in a direction parallel to the first axis a, so that the first transmission assembly 50 drives the cleaning assembly 31 to rotate around the first axis a through the transmission shaft 33 .

[0060] In order to connect the transmission plate 321 with the transmission shaft 33, as shown in FIG. Figure 1-2 As shown, the second transmission assembly 32 further includes a sleeve 323 that is sleeved on the transmission shaft 33. A plurality of transmission plates 321 are spaced apart and disposed on the outer wall of the sleeve 323 around the first axis a. Thus, the transmission plates 321 are connected to the transmission shaft 33 via the sleeve 323, thereby facilitating the production and assembly of the transmission plates 321, sleeve 323, and transmission shaft 33.

[0061] Optionally, the transmission plate 321 is welded to the sleeve 323 , and the sleeve 323 and the transmission shaft 33 are connected via fasteners.

[0062] In some embodiments, such as Figure 1-2 As shown, the cleaning assembly 31 includes a plurality of brackets 311 and cleaning members 313 corresponding to each bracket 311. One side of the brackets 311 is connected to the side wall of the drive shaft 33. The plurality of brackets 311 are arranged around the first axis a, and the cleaning members 313 are arranged on the other side of the corresponding brackets 311. In this way, by configuring the cleaning assembly 31 to include the brackets 311 and the cleaning members 313, the brackets 311 support the cleaning members 313, and a certain distance is maintained between the cleaning members 313 and the drive shaft 33, so that the cleaning members 313 can contact the inner wall of the furnace hood 20, thereby cleaning volatile substances attached to the inner wall of the furnace hood 20.

[0063] Alternatively, as Figure 2 As shown, the bracket 311 is fixedly connected to the transmission shaft 33 via fasteners.

[0064] In one embodiment, Figure 2 As shown, the number of the cleaning members 313 and the number of the brackets 311 are both 4. In other embodiments, the number of the cleaning members 313 and the number of the brackets 311 can also be set in other ways according to the needs of use, which is not limited here.

[0065] Alternatively, as Figure 1-2As shown, the cleaning member 313 is arranged in a direction parallel to the first axis a to increase the contact area between the cleaning member 313 and the inner wall of the furnace hood 20 , so that the cleaning member 313 can clean the inner wall of the furnace hood 20 more comprehensively.

[0066] To ensure a reliable connection between the cleaning member 313 and the bracket 311, in some embodiments, a mounting groove is provided on the side of the bracket 311 away from the transmission shaft 33. The cleaning assembly 31 also includes a clamping plate assembly corresponding to each cleaning member 313. The clamping plate assembly includes two clamping plates respectively provided on either side of the corresponding cleaning member 313. The two clamping plates are provided in the corresponding mounting grooves and connected to the bracket 311. In this way, by providing the clamping plate assembly, it is convenient to fix the clamping plate assembly to the cleaning member 313, so that the cleaning member 313 is connected to the bracket 311 by means of the clamping plate assembly. Since the cleaning member 313 can be made of a relatively special material, the provision of the clamping plate assembly facilitates the assembly of the cleaning member 313 and the bracket 311, and ensures a reliable connection between the cleaning member 313 and the bracket 311.

[0067] Specifically, the two clamps are arranged along the extension direction of the corresponding cleaning member 313, and the clamps extend from one end of the cleaning member 313 to the other end of the cleaning member 313 to increase the contact area between the clamps and the cleaning member 313 to prevent the cleaning member 313 from separating from the clamps.

[0068] Optionally, the clamping plate and the cleaning member 313 are connected by fasteners, and the clamping plate and the bracket 311 are connected by fasteners.

[0069] Furthermore, if Figure 2 As shown, the bracket 311 includes a mounting tube 3111 having a mounting groove. The mounting tube 3111 is arranged along the extending direction of the mounting groove. The mounting groove passes through one end of the mounting tube 3111. The other end of the mounting tube 3111 is provided with a blocking portion 3112. Thus, by providing the mounting tube 3111 and the blocking portion 3112, when assembling the splint assembly with the mounting tube 3111, the splint assembly can be inserted into the mounting groove from one end of the mounting tube 3111 through the mounting groove. The splint assembly is then fixedly connected to the mounting tube 3111 by fasteners, making the splint assembly easy to replace and clean.

[0070] Optionally, the sealing portion 3112 and the mounting tube 3111 may be connected by welding.

[0071] Figure 5 for Figure 1 A side view of the furnace hood in the illustrated embodiment; Figure 6 for Figure 1 Front view of the furnace hood in the illustrated embodiment.

[0072] In some embodiments, such as Figure 2 As shown, the cleaning member 313 includes brush wires, such as Figure 5-6As shown, the outer periphery of the furnace hood 20 is provided with an oiling portion 70, within which is an oiling port 71 communicating with the accommodating space 21. At least one scraper 80 is disposed within the oiling port 71, connected to the oiling portion 70. One side of the scraper 80 protrudes into the accommodating space 21, allowing the scraper 80 to abut against the cleaning member 313. Thus, the cleaning member 313 includes a brush to scrape away volatiles adhering to the inner wall of the furnace hood 20, for example, to liquefy tar adhering to the furnace hood 20. By providing the oiling portion 70 on the furnace hood 20 and defining the oiling port 71 communicating with the accommodating space 21, a portion of the volatiles scraped off by the cleaning member 313 can be directly discharged from the furnace hood 20 through the oiling port 71. By providing a scraper 80 at the lower oil port 71 and protruding into the accommodating space 21, the scraper 80 can abut against the cleaning member 313, thereby scraping off volatiles from the cleaning member 313 and discharging the scraped volatiles through the lower oil port 71, thereby maintaining the effective cleaning performance of the cleaning member 313. Furthermore, when the burner head 10 stops rotating, the cleaning member 313 is subjected to frictional resistance from the inner wall of the furnace cover 20 and collision resistance from the scraper 80, causing it to stop rotating.

[0073] Optionally, the brush wire can be made of high-toughness and wear-resistant metal brush wire, so that the cleaning member 313 undergoes a large deformation when passing through the scraper 80, so that the volatiles adhering to the cleaning member 313 are ejected or thrown out when the cleaning member 313 leaves the scraper 80, so as to further clean the volatiles on the cleaning member 313, so that the cleaning member 313 maintains good cleaning ability, so as to clean the furnace hood more efficiently.

[0074] Optionally, the scraper 80 may be connected to the oil lower portion 70 by welding.

[0075] In some embodiments, the lower oil port 71 is used to communicate with a recovery tank, so that tar and other attachments scraped off by the cleaning member 313 can flow into the recovery tank through the lower oil port 71 for subsequent processing.

[0076] Furthermore, the recovery tank is connected to the water seal tank. When the tar in the recovery tank accumulates to a certain amount, the tar can be fished out through the water seal tank, so that the tar recovery is completed in a sealed environment.

[0077] In some embodiments, such as Figure 5-6 As shown, the shape of the lower oil port 71 is constructed to match the shape of the lower oil portion 70 so that the cross-sectional dimension of the lower oil port 71 in the direction perpendicular to the direction from one end connected to the accommodating space 21 to the other end is larger, thereby facilitating the scraped volatiles to flow out through the lower oil port 71.

[0078] In some embodiments, combined Figure 1 and Figure 5-6As shown, a support member 90 is provided within the accommodating space 21. The support member 90 is arranged in a direction perpendicular to the first axis a, and the two ends of the support member 90 are respectively connected to the inner wall of the furnace cover 20. The support member 90 is provided with a limiting groove that passes through the support member 90 in a direction parallel to the first axis a, and the transmission shaft 33 is inserted into the limiting groove. In this way, by providing the support member 90 and connecting it to the transmission shaft 33, support is provided for the cleaning device 30. By providing the limiting groove on the support member 90 for the transmission shaft 33 to pass through, the transmission shaft 33 is retained in the limiting groove, thereby positioning the cleaning device 30 within the furnace cover 20.

[0079] Optionally, in a direction perpendicular to the first axis a, a limiting groove passes through one side of the support member 90 to facilitate placing the transmission shaft 33 into the limiting groove.

[0080] Furthermore, if Figure 1-2 As shown, a first limiting portion 34 is provided on the side wall of the transmission shaft 33, and the first limiting portion 34 is provided between the support member 90 and the cleaning assembly 31. In this way, by providing the first limiting portion 34, the first limiting portion 34 is limited by the support member 90 in a direction parallel to the first axis a.

[0081] Specifically, if Figure 2 As shown, the first limiting portion 34 is disposed around the outer circumference of the transmission shaft 33. Optionally, the first limiting portion 34 is connected to the transmission shaft 33 via a fastener.

[0082] In some embodiments, such as Figure 1-2 As shown, a stopper 100 is provided protruding from the accommodating space 21 on the side of the furnace cover 20 opposite the opening 11. A stopper 100 is recessed into the stopper 100 on the side away from the furnace cover 20 to form a stopper hole. One end of the transmission shaft 33 is inserted into the stopper hole. Thus, by providing the stopper 100, one end of the transmission shaft 33 is retained in the stopper hole, further positioning the transmission shaft 33.

[0083] Furthermore, if Figure 1-2 As shown, a second limiting portion 35 is protruded from the side wall of the transmission shaft 33, and the second limiting portion 35 is arranged between the cleaning assembly 31 and the limiting member 100, so that the second limiting portion 35 is limited by the limiting member 100 on one side in a direction parallel to the first axis a.

[0084] Specifically, if Figure 2 As shown, the second limiting member 100 is disposed around the outer circumference of the transmission shaft 33. The second limiting portion 35 is connected to the transmission shaft 33 via a fastener.

[0085] Therefore, in the above embodiment, by providing a support member 90 and a stopper 100 within the furnace cover 20, the transmission shaft 33 is positioned by the stopper groove and the stopper hole, respectively, in a direction perpendicular to the first axis a. In addition, by providing a first stopper 34 corresponding to the support member 90 and a second stopper 35 corresponding to the stopper 100 on the transmission shaft 33, the transmission shaft 33 is positioned by the support member 90 and the stopper 100, respectively, in a direction parallel to the first axis a. This ensures that the cleaning device 30 is positioned within the furnace cover 20, enabling the cleaning device 30 to perform stable and effective cleaning.

[0086] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
