Description

Technical Field

[0001] The present invention relates to the technical field of mixing equipment, and particularly to a mixing equipment for preparing erosion-resistant slag-separating spraying coating. Background Art

[0002] During the transportation of steel slag, spraying a layer of spraying coating (slag ladle spraying coating) on the inner wall of the slag ladle to prevent the steel slag from sticking to the ladle can greatly improve the automatic tipping rate of the slag ladle, avoid the phenomenon of steel slag sticking to the ladle, reduce the slag cleaning operation during the tipping process, and extend the service life of the slag ladle. The slag separator is composed of high-temperature resistant ultrafine powder, suspending agent, slag-resistant agent, binder and auxiliary additives. Water is added on-site and a special pulping equipment is used to configure it into a heat-resistant slurry with a certain viscosity and high adhesion. A special spraying device is used to spray on the inner surface of the metallurgical equipment to form a molten slag isolation layer.

[0003] When the mixing equipment in the prior art is in use, a rotating mixing rod is usually used to mix the powder materials. During the use of a conventional mixing rod, the powder materials in the vertical direction cannot be quickly mixed, resulting in a long time for the powder materials to be completely mixed and low mixing efficiency. Summary of the Invention

A material turning mechanism is further connected to the lifting mechanism.

[0006] Preferably, the lifting mechanism includes two chute brackets. The two chute brackets are fixedly connected to the top cover in parallel. Two sliders are slidably connected to each chute bracket. The two sliders are symmetrically arranged. Two sliders with corresponding positions on different chute brackets are connected with a rotating rod. The rotating rod is rotatably connected to the slider. An elevating block is connected between the two rotating rods. The elevating block is rotatably connected to the rotating rod.

[0007] Preferably, the transmission mechanism includes two connecting brackets which are fixedly connected to the top cover in parallel. A transmission rod is rotatably connected to the two connecting brackets. One end of the transmission rod is fixedly connected with a first bevel gear. The transmission mechanism further includes a reciprocating lead screw, the lower end of which is rotatably connected to the top cover, and the upper end of which is rotatably connected to a fixed bracket. The fixed bracket is fixedly connected to the torsion mechanism. A second bevel gear is also fixedly connected to the reciprocating lead screw. The first bevel gear meshes with the second bevel gear. The reciprocating lead screw is threadedly connected to the lifting block. The other end of the transmission rod is connected with a driven component.

[0008] Preferably, the driven component includes a second spur gear which is rotatably connected to the end of the transmission rod. A plurality of support brackets are evenly and fixedly connected to the outer wall of the barrel. A second spur gear ring is fixedly connected to the support brackets. The second spur gear meshes with the second spur gear ring. A first end face ratchet is fixedly connected to the second spur gear. A second end face ratchet is slidably connected to the transmission rod. A baffle is also fixedly connected to the transmission rod. A spring is connected between the baffle and the second end face ratchet. The second end face ratchet abuts against the first end face ratchet under the push of the spring.

[0009] Preferably, the torsion mechanism includes a lifting bracket which is rotatably connected to two rotating rods. Two sliders two are slidably connected to the lifting bracket. The two sliders two are symmetrically arranged. A first guide rod and a second guide rod are respectively fixedly connected to the two side faces of the slider two. Two sleeves are symmetrically and fixedly connected to the two rotating rods. A guiding groove is formed in the sleeve. The first guide rod is slidably connected to the guiding groove on the same side. A straight plate is also fixedly connected to the top cover. A fixed bracket is fixedly connected to the top end of the straight plate. Two parallelogram-shaped sliding grooves are symmetrically formed on both sides of the straight plate. The second guide rod is slidably connected to the parallelogram-shaped sliding groove on the same side. Check slopes are arranged at the inflection points at the upper and lower ends of the parallelogram-shaped sliding groove.

[0010] Preferably, the second guide rod includes an elastic rod which can be telescoped. The elastic rod is fixedly connected to the slider two. A ring sleeve is rotatably connected to the elastic rod. The ring sleeve is slidably connected to the parallelogram-shaped sliding groove. A ball which can roll in all directions is connected to the end of the elastic rod. The ball abuts against the bottom of the parallelogram-shaped sliding groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, through the provided lifting mechanism, the material turning mechanism can be driven to move up and down. During the upward movement of the material turning mechanism from the bottom, the powder at the bottom of the barrel can be shoveled up and moved to the upper part, thereby realizing the mixing of the powder in the vertical direction and improving the mixing effect of the powder.

[0015] 2. In the present invention, through the provided torsion mechanism, during the movement of the lifting mechanism, the angle of the turning plate can be automatically adjusted, so that the turning plate remains vertical when moving downward to reduce the resistance, and can be combined into a concave state when moving upward to accommodate the powder at the bottom of the barrel.

[0016] 3. In the present invention, through the provided transmission mechanism, the lifting mechanism can be driven to move when the top cover rotates. By providing the end face ratchet one and the end face ratchet two, when the driving motor changes the rotation direction and the end face ratchet one and the end face ratchet two cannot transmit power, the top cover will still rotate, while the lifting mechanism will no longer move, so that the height of the turning plate will no longer move. At this time, the turning plate will still rotate, playing the role of stirring the powder in the horizontal direction. Different rotation directions of the driving motor can make the turning plate play different roles. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical staff in the art without creative work belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 11 , the present invention provides a technical solution:

[0031] An erosion-resistant slag-separating spraying coating preparation stirring device, comprising a material storage bucket 1. The material storage bucket 1 includes a bucket body 101, and a top cover 102 is rotatably connected to the top end of the bucket body 101. A driving mechanism 2 is arranged on the material storage bucket 1. The driving mechanism 2 includes a driving motor 201, the driving motor 201 is fixedly connected to the bucket body 101, a first spur gear 202 is fixedly connected to the output shaft of the driving motor 201, a first spur gear ring 203 is fixedly connected to the side of the top cover 102, and the first spur gear 202 meshes with the first spur gear ring 203. A lifting mechanism 3 is further arranged on the top cover 102. The lifting mechanism 3 is connected to a transmission mechanism 4 and a torsion mechanism 5. The transmission mechanism 4 and the torsion mechanism 5 are connected to the top cover 102. A material turning mechanism 6 is also connected to the lifting mechanism 3.

[0032] In this embodiment, the lifting mechanism 3 includes two chute brackets 301. The two chute brackets 301 are fixedly connected to the top cover 102 in parallel. Two slider ones 302 are slidably connected to each chute bracket 301. The two slider ones 302 are symmetrically arranged. A rotating rod 303 is connected to two slider ones 302 with corresponding positions on different chute brackets 301. The rotating rod 303 is rotatably connected to the slider one 302. A lifting block 304 is connected between the two rotating rods 303. The lifting block 304 is rotatably connected to the rotating rod 303.

[0033] In this embodiment, the transmission mechanism 4 includes two connecting brackets 401. The two connecting brackets 401 are fixedly connected to the top cover 102 in parallel. A transmission rod 402 is rotatably connected to the two connecting brackets 401. A first bevel gear 403 is fixedly connected to one end of the transmission rod 402. The transmission mechanism 4 further includes a reciprocating lead screw 404. The lower end of the reciprocating lead screw 404 is rotatably connected to the top cover 102. The upper end of the reciprocating lead screw 404 is rotatably connected to a fixed bracket 405. The fixed bracket 405 is fixedly connected to the torsion mechanism 5. A second bevel gear 406 is also fixedly connected to the reciprocating lead screw 404. The first bevel gear 403 meshes with the second bevel gear 406. The reciprocating lead screw 404 is threadedly connected to the lifting block 304. A driven assembly 407 is connected to the other end of the transmission rod 402.

[0034] In this embodiment, the driven assembly 407 includes a second spur gear 4071 which is rotatably connected to the end of the transmission rod 402. A plurality of support brackets 4072 are uniformly and fixedly connected to the outer wall of the barrel body 101. A second spur gear ring 4073 is fixedly connected to the support bracket 4072. The second spur gear 4071 meshes with the second spur gear ring 4073. A first end face ratchet 4074 is fixedly connected to the second spur gear 4071. A second end face ratchet 4075 is slidably connected to the transmission rod 402. A baffle 4076 is also fixedly connected to the transmission rod 402. A spring 4077 is connected between the baffle 4076 and the second end face ratchet 4075. The second end face ratchet 4075 abuts against the first end face ratchet 4074 under the push of the spring 4077.

[0035] In this embodiment, the torsion mechanism 5 includes a lifting bracket 501 which is rotatably connected to two rotating rods 303. Two second sliders 502 are slidably connected to the lifting bracket 501. The two second sliders 502 are symmetrically arranged. A first guide rod 503 and a second guide rod 504 are respectively fixedly connected to the two side faces of the second slider 502. Two sleeves 505 are symmetrically and fixedly connected to the two rotating rods 303. A guiding groove 506 is formed in the sleeve 505. The first guide rod 503 is slidably connected in the guiding groove 506 on the same side. A straight plate 507 is also fixedly connected to the top cover 102. A fixed bracket 405 is fixedly connected to the top end of the straight plate 507. Two parallelogram-shaped sliding grooves 508 are symmetrically formed on both sides of the straight plate 507. The second guide rod 504 is slidably connected in the parallelogram-shaped sliding groove 508 on the same side. Check slopes 509 are arranged at the inflection points at the upper and lower ends of the parallelogram-shaped sliding groove 508.

[0036] In this embodiment, the check slope 509 is used to control the moving direction of the second guide rod 504 in the parallelogram-shaped sliding groove 508. When the second guide rod 504 passes through the check slope 509, the elastic rod 5041 is compressed and contracted. After the second guide rod 504 completely passes through the check slope 509, the elastic rod 5041 automatically extends. At this time, the check slope 509 will block the second guide rod 504, so that the second guide rod 504 can only move vertically and cannot return the same way.

[0037] In this embodiment, the second guide rod 504 includes a telescopic elastic rod 5041 which is fixedly connected to the second slider 502. A collar 5042 is rotatably connected to the elastic rod 5041. The collar 5042 is slidably connected in the parallelogram-shaped sliding groove 508. A ball 5043 capable of universal rolling is connected to the end of the elastic rod 5041. The ball 5043 abuts against the bottom of the parallelogram-shaped sliding groove 508.

[0038] In this embodiment, when the second guide rod 504 slides in the parallelogram chute 508, the collar 5042 rotatably connected to the elastic rod 5041 can greatly reduce the friction between the second guide rod 504 and the side wall of the parallelogram chute 508. At the same time, the arrangement of the ball 5043 can greatly reduce the friction between the second guide rod 504 and the bottom of the parallelogram chute 508, thereby reducing the wear of the second guide rod 504 and the parallelogram chute 508 and effectively extending the service life of the second guide rod 504 and the parallelogram chute 508.

[0039] In this embodiment, the material turning mechanism 6 includes four end caps 601, and the four end caps 601 are fixedly connected to the ends of the two rotating rods 303 in a pairwise symmetric manner. The material turning mechanism 6 further includes two symmetrically arranged material turning plates 602. Two first connecting columns 603 are symmetrically arranged on the end caps 601. Two second connecting columns 604 are symmetrically arranged at both ends of the material turning plate 602. A bent connecting rod 605 is hinged between the first connecting column 603 and the corresponding second connecting column 604.

[0040] In this embodiment, the presence of the bent connecting rod 605 enables the material turning plate 602 to rotate synchronously with the end cap 601. The bending of the bent connecting rod 605 prevents the two bent connecting rods 605 from interfering with each other during the rotation of the material turning plate 602, which may cause the structure to malfunction. At the same time, chamfering is performed on the outer side of the bent connecting rod 605, which can greatly reduce the resistance received when the bent connecting rod 605 moves downward.

[0041] In this embodiment, a stirring rod 7 is also fixedly connected to the top cover 102.

[0042] When the erosion-resistant slag separating spraying coating preparation and stirring equipment is working, the working process is as follows:

[0043] During use, the driving motor 201 is started. The driving motor 201 drives the top cover 102 to rotate through the meshing spur gear one 202 and spur gear ring one 203. The top cover 102 drives the stirring rod 7 to rotate, mixing the powder in the mixing barrel body 101. The top cover 102 also drives the transmission rod 402 thereon to rotate together. Since the spur gear two 4071 on the transmission rod 402 meshes with the spur gear ring two 4073 fixedly connected to the barrel body 101, the spur gear two 4071 is driven to rotate. When the top cover 102 drives the spur gear two 4071 to rotate forward, the end face ratchet one 4074 engages with the end face ratchet two 4075, and the spur gear two 4071 drives the transmission rod 402 to rotate self. When the top cover 102 drives the spur gear two 4071 to rotate backward, the end face ratchet one 4074 and the end face ratchet two 4075 slip, and the transmission rod 402 does not rotate self.

[0044] When the transmission rod 402 rotates on its own axis, the transmission rod 402 drives the reciprocating lead screw 404 to rotate through the meshing bevel gear one 403 and bevel gear two 406. The reciprocating lead screw 404 drives the lifting block 304 engaged therewith to reciprocate up and down. Since the rotating rod 303 is rotatably connected to the slider one 302, the lifting block 304 will drive the rotating rod 303 to reciprocate up and down along the chute bracket 301. The lifting bracket 501 and the material turning mechanism 6 connected to the rotating rod 303 will also reciprocate up and down together;

[0045] The slider two 502 on the lifting bracket 501 also reciprocates up and down. Since the guide rod two 504 on the slider two 502 is slidably connected in the parallelogram chute 508, when the guide rod two 504 moves into the two diagonal slots of the parallelogram chute 508, the slider two 502 will be driven to slide along the lifting bracket 501. Since the guide rod one 503 is slidably connected in the guiding slot 506, the laterally moving guide rod one 503 will drive the sleeve 505 to rotate a certain angle. The sleeve 505 drives the rotating rod 303 fixedly connected thereto to rotate a certain angle. The rotating rod 303 drives the material turning plate 602 to rotate a certain angle through the end cover 601 and the bent connecting rod 605;

[0046] When the guide rod two 504 moves in the upper diagonal slot, the two material turning plates 602 are finally turned into a vertical state, and all the powder remaining on the material turning plates 602 is spilled. Then the material turning plates 602 maintain the vertical state and move downward. When the guide rod two 504 moves in the lower diagonal slot, the lower ends of the two vertical material turning plates 602 move closer to each other inward, forming a concave state, so as to shovel up the powder at the bottom and retain it on the two material turning plates 602. Then the material turning plates 602 maintain the concave state and move upward.

[0047] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
