Description

Technical Field

[0001] This invention relates to a centrifuge for processing reduction tanks, belonging to the field of mechanical equipment. Background Technology

[0002] The reduction tank has a pipe diameter of DN1100mm~1200mm. During production, the pipe fittings are manufactured using a centrifugal motor to drive the pipe mold rotation, and then cast using a casting machine. After forming, the pipe fittings need to be removed from the mold using a pipe pulling machine. Therefore, in application number 201910807460... Patent document .8 discloses a hot mold centrifugal casting pipe machine. The casting and spraying equipment disclosed therein is set on the same side of the centrifugal host, which occupies a large space during installation. Before casting the pipe fitting, the socket end of the pipe mold needs to be blocked with a sand core. The existing mandrel in the prior art is like the mandrel (T) disclosed in the aforementioned prior art document. The mandrel pressure plate is always installed on the mandrel device. During mandrel installation, it is only necessary to flip up the sand core placed on the mandrel flipping machine and then install the flipped sand core onto the mandrel pressure plate by moving the mandrel device. Then, the mandrel device installs the sand core onto the socket end of the pipe mold. The mandrel pressure hook is directly pressed on the sand core. In the prior art, one mandrel can only be used for mandrel installation on one pipe fitting of the same diameter. Therefore, the cost is large and the work efficiency is relatively low. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a centrifuge with a reasonable structural design for processing reduction tanks.

[0004] The technical solution adopted by this invention to solve the above problems is as follows: A centrifuge for processing reduction tanks includes a centrifuge main unit, a casting carriage, a spraying carriage, and a tube pulling machine. The casting carriage and spraying carriage are located at opposite ends of the centrifuge main unit. Its structural features include: a molten steel transfer carriage, a core-loading trolley, and a protective cover. The centrifuge main unit is located inside the protective cover. The molten steel transfer carriage cooperates with the casting carriage. The centrifuge main unit cooperates with the core-loading trolley, the casting carriage, the tube pulling machine, and the spraying carriage. The molten steel transfer carriage includes a transfer device, a positioning device, and a conveying device. The conveying device is mounted on the transfer device, and the transfer device cooperates with the positioning device. The molten steel transfer carriage allows for the simultaneous transfer of molten steel from multiple ladles, enabling simultaneous casting by multiple casting machines. The core-loading trolley can be used to core molds of various pipe diameters when processing pipe fittings of different diameters. One core-loading trolley can work in conjunction with multiple centrifuge main units.

[0005] Furthermore, the pipe pulling machine works in conjunction with a pipe-holding overhead crane. The pipe-holding overhead crane can transfer the pipes pulled out by the pipe pulling machine to the next work station.

[0006] Furthermore, the transfer device includes a transfer frame, transfer wheels, a transfer reducer, and a transfer support. The transfer wheels, reducer, and support are all mounted on the transfer frame. The reducer drives the transfer wheels. The conveying device includes a large ladle conveying device and a small ladle conveying device, both mounted on the transfer support. The positioning device cooperates with the transfer frame. This molten steel transfer car allows for the transfer of molten steel during the processing of pipe fittings with two different diameters, improving processing efficiency. Simultaneously, the positioning device ensures accurate positioning of the ladle when it is transferred to the casting station.

[0007] Furthermore, the transfer device also includes a weighing sensor and a support limiting post, both of which are mounted on the transfer carriage frame and positioned between the transfer carriage frame and the transfer support. The support limiting post cooperates with the weighing sensor. The weighing sensor can be used to weigh the molten steel in the ladle, preventing excessive or insufficient molten steel to improve processing quality. The support limiting post can be used to limit the movement of the transfer support, preventing the support from damaging the weighing sensor.

[0008] Furthermore, the transfer wheel is located on a wheel track, and wheel stops are provided at both ends of the wheel track to restrict the position of the transfer wheel.

[0009] Furthermore, the transfer wheel contacts the wheel stop. When the transfer frame moves to the end of the wheel track, the transfer wheel can be limited by the wheel stop contacting the transfer wheel.

[0010] Furthermore, the positioning device includes a positioning bracket, a positioning cylinder, a positioning support rod, a positioning roller, a positioning plate, and a positioning slot. The cylinder barrel of the positioning cylinder and one end of the positioning support rod are both mounted on the positioning bracket. The positioning roller is mounted on the other end of the positioning support rod. The piston rod of the positioning cylinder is connected to the positioning support rod. The positioning plate is mounted on the transfer vehicle frame, and the positioning slot is mounted on the positioning plate. The positioning slot has a trapezoidal structure, and the positioning roller is located within the positioning slot. The positioning device can be used to limit the movement of the transfer vehicle, allowing the ladle to be aligned with the casting station, thus improving the efficiency of steel transfer and casting. The trapezoidal structure of the positioning slot facilitates the insertion of the positioning roller into the slot, achieving positioning of the transfer device when the positioning roller is engaged.

[0011] Furthermore, the large package conveying device includes a large package conveying bracket, a large package conveying roller, a large package conveying sprocket, a large package conveying chain, a large package conveying reducer, and a large package tensioning sprocket. The large package conveying bracket is mounted on a transfer bracket. The large package conveying roller and the large package tensioning sprocket are both mounted on the large package conveying bracket. The large package conveying sprocket is mounted on the large package conveying roller. Adjacent large package conveying sprockets and large package tensioning sprockets are driven by the large package conveying chain. The large package conveying reducer is used to drive the large package conveying roller.

[0012] Furthermore, the small package conveying device includes a small package conveying bracket, a small package conveying roller, a small package conveying sprocket, a small package conveying chain, a small package conveying reducer, and a small package tensioning sprocket. The small package conveying bracket is mounted on a transfer bracket. The small package conveying roller and the small package tensioning sprocket are both mounted on the small package conveying bracket. The small package conveying sprocket is mounted on the small package conveying roller. Adjacent small package conveying sprockets and small package tensioning sprockets are driven by the small package conveying chain. The small package conveying reducer is used to drive the small package conveying roller.

[0013] Furthermore, the core-loading trolley includes a trolley body, a lifting device, a pusher plate device, a core-loading device, and a core-turning machine. The lifting device is mounted on the trolley body, and the core-loading device is mounted on the lifting device. The core-turning machine cooperates with the pusher plate device, and the pusher plate device cooperates with the core-loading device. The core-turning machine flips the sand core and the core-pressing plate from a horizontal state to a vertical state. After the pusher plate device removes the vertically positioned sand core and core-pressing plate, the trolley body moves to the front of the pusher plate device, and the core-loading device removes the sand core and core-pressing plate and installs them at the socket end of the mold.

[0014] Furthermore, the pusher device includes a pusher frame, a pusher body, pusher rollers, a pusher cylinder, a pusher connecting rod, a pusher locking mechanism, and a pusher cylinder seat. The pusher body is mounted on the pusher frame via the pusher rollers, and the pusher frame and the pusher body are connected by the pusher connecting rod. The cylinder barrel of the pusher cylinder is mounted on the pusher frame via the pusher cylinder seat, and the piston rod of the pusher cylinder is connected to the pusher body. The pusher locking mechanism is mounted on the pusher body. The pusher cylinder pushes the pusher body, causing the pusher rollers to move on the pusher frame, and the pusher locking mechanism locks the sand core and the pressure core plate.

[0015] Furthermore, there are two push plate connecting rods, designated as Push Plate Connector No. 1 and Push Plate Connector No. 2. One end of Push Plate Connector No. 1 is connected to the push plate frame, and the other end of Push Plate Connector No. 1 is connected to one end of Push Plate Connector No. 2. The other end of Push Plate Connector No. 2 is connected to the push plate body. The use of push plate connecting rods makes the movement of the push plate body more stable.

[0016] Furthermore, the push plate locking mechanism includes a push plate locking cylinder and a push plate locking block. The push plate locking cylinder is mounted on the push plate body, and the push plate locking block is mounted on the push plate locking cylinder. The core plate can be pressed tightly by extending and retracting the push plate locking block driven by the push plate locking cylinder.

[0017] Furthermore, the lifting device includes a lifting outer sleeve, a lifting inner cylinder, a lifting seat, and a screw jack. The lifting inner cylinder is disposed inside the lifting outer sleeve, the lifting seat is disposed on top of the lifting outer sleeve, and the screw jack is disposed on the lifting seat, and the screw jack is used to drive the lifting inner cylinder. The screw jack can drive the lifting inner cylinder to move up and down within the lifting outer sleeve.

[0018] Furthermore, the screw jack is equipped with bearing structures at the connections between the screw, the lifting seat, and the inner lifting cylinder. These bearing structures ensure that the screw, the inner lifting cylinder, and the outer lifting sleeve remain coaxial, thus extending their service life.

[0019] Furthermore, an encoder assembly is provided within the main body of the crane. The encoder assembly can be used to locate the position of the upper crane, making the positioning more accurate.

[0020] Furthermore, the core-turning machine includes a core-turning base, a turning frame, a moving frame, a turning cylinder base, a turning cylinder, a moving lift, a pressing plate bracket, and cylinder lugs. The turning frame and the turning cylinder base are both mounted on the core-turning base, and the moving frame and the moving lift are both mounted on the turning frame. The moving lift drives the moving frame. The cylinder barrel of the turning cylinder is mounted on the turning cylinder base. The piston rod of the turning cylinder is connected to the cylinder lugs via adjusting nuts. The cylinder lugs are connected to the turning frame, and the pressing plate bracket is mounted on the moving frame. The pressing plate bracket prevents the entire sand core and pressing plate from tipping over and falling when the core is turned to a vertical position due to its forward center. The adjusting nuts allow for adjustment of the cylinder lugs to ensure that the vertical plane is adjusted vertically after turning, making the sand core parallel to the push plate body.

[0021] Furthermore, the movable frame is provided with adjustment holes. By providing adjustment holes, it can be ensured that the sand core and the push plate body are parallel in the left and right directions of the vertical plane after being flipped up.

[0022] Furthermore, the protective cover includes a main body and a movable dust collection hood, which is mounted on the main body. The top of the main body is equipped with a cooling fan, a dust removal pipe, and a steam removal pipe, while the bottom of the main body has wheels. The cooling fan, dust removal pipe, and steam removal pipe respectively achieve the functions of cooling, dust removal, and steam removal.

[0023] Furthermore, the movable vacuum hood is slidably mounted on the protective cover body via vacuum hood wheels. The protective cover body is connected to the cylinder of the vacuum hood cylinder, and the piston rod of the vacuum hood cylinder is connected to the movable vacuum hood. The side wall of the movable vacuum hood is provided with vacuum hood limiting wheels, and the side wall of the protective cover body is provided with vacuum hood limiting grooves. The vacuum hood limiting wheels are located within the vacuum hood limiting grooves. The vacuum hood cylinder can drive the movable vacuum hood to move on the protective cover body via the vacuum hood wheels. The provided vacuum hood limiting wheels and vacuum hood limiting grooves can limit the movement of the movable vacuum hood.

[0024] Compared with the prior art, the present invention has the following advantages: The centrifuge for processing reduction ladle can be used for casting pipe fittings with diameters of DN1100mm to 1200mm when processed by a centrifugal main unit. During casting, molten steel is transferred to the casting machine via a molten steel transfer car. The molten steel transfer car can realize the synchronous transfer of molten steel in the large ladle and the small ladle through the set large ladle conveying device and small ladle conveying device. Molten steel can be poured into two casting machines at the same time. The molten steel in the large ladle is used to cast reduction ladle with diameters of DN1100 to 1200mm, and the molten steel in the small ladle is used to cast center pipe with diameters of DN550 to 600mm. Pipe fittings of two diameters are processed at the same time to improve the transfer efficiency of molten steel. The set positioning device can make the molten steel transfer car accurately positioned at the casting station to improve the casting efficiency.

[0025] One mandating trolley can be used to mandulate pipes of the same diameter simultaneously when multiple centrifuge units are processing them. Since the pipe diameters are the same, the sand cores are also the same size. The sand core model corresponds to the mandrel plate. During mandating, the sand core and mandrel plate are placed on a mandrel flipping machine. The flipping machine flips the sand core and mandrel plate. After the flipped sand core and mandrel plate are removed by a pusher plate device, the mandrel plate carrying the sand core can be installed on the mandating device. The mandating device can then synchronously install the sand core and mandrel plate onto the socket end of the pipe mold. The mandrel plate can be pressed tightly by the mandrel hook, thus completing the mandating process. This mandating trolley has the advantages of wide versatility and high working efficiency.

[0075] Specifically, during the processing of pipe fittings, the centrifuge for reducing tank pipes uses a core-mounting trolley B to install sand cores at the socket end of the pipe mold, then a molten steel transfer car A to transport them to the casting station. The casting trolley E pours the molten steel into the pipe mold, the centrifuge host D drives the pipe mold to rotate and form the pipe fitting inside the mold, the pipe fitting is pulled out by the pipe pulling machine G, and the pulled-out pipe fitting is transferred to the next station by the pipe holding machine. Finally, the inner wall of the pipe mold is cleaned by the spraying trolley F.

[0076] When transferring molten steel, the molten steel transfer car A can simultaneously load molten steel from large and small ladles via the large ladle conveying device A3 and the small ladle conveying device A4.

The second and third rollers A42 have a small package conveying sprocket A43 at the other end, which is also driven by a small package conveying chain A44 and a small package tensioning sprocket A46. The third and fourth rollers A42 have a small package conveying roller at one end. The conveyor sprocket A43 is driven by the small package tensioning sprocket A46 via the small package conveyor chain A44. The other end of the fourth and fifth package conveyor rollers A42 is equipped with small package conveyor sprockets A43, which are driven by the small package tensioning sprockets A46 via the small package conveyor chain A44. This allows the four small package conveyor chains A44 to be arranged in a serpentine pattern, ensuring that the small package conveyor chains A44 are always taut and that the five small package conveyor rollers A42 are subjected to uniform force to ensure stability during conveying.

[0079] During core loading, the core and pressing plate B6 are simultaneously placed on the core flipping machine B4 by the core loading crane B45. The flipping frame B42 is driven by the flipping cylinder B45 to flip the core and pressing plate B6 from a horizontal to a vertical position. The push plate device B5 pushes the push plate body B52 by the push plate cylinder B54, causing the push plate roller B53 to roll on the push plate frame B51, so that the vertical core and pressing plate B6 fit into the push plate body B52. The push plate locking cylinder B561 locks the push plate. B562 is pushed out, causing the push plate locking block B562 to lock the sand core and the pressing plate B6. The push plate cylinder B54 pulls back the push plate body B52. The trolley body B1 moves the core loading device B3 to the front of the push plate device B5, and the lifting device B2 adjusts the position of the core loading device B3 so that the pressing plate B6 carrying the sand core is installed on the core loading device B3. The trolley body B1 is moved so that the core loading device B3 installs the sand core on the socket end of the tube mold, and at the same time, the pressing hook presses the pressing plate B6 tightly.
