Description

Technical Field

[0001] This utility model belongs to the field of iron trough castable technology, specifically relating to a batching device for the production of iron trough castable. Background Technology

[0002] Iron trough castable (referred to as iron trough material) series products are designed for different parts and usage conditions of the tapping trough of large and medium-sized blast furnaces. They adopt the principle of low-cement and ultra-low-cement castables, using different types of corundum and silicon carbide as the main raw materials, combined with various ultrafine powders, additives and binders, and are made according to the formula ratio. They have the characteristics of low water addition during construction, good fluidity, high strength, corrosion resistance, erosion resistance, oxidation resistance and excellent high stability.

[0003] Currently, when preparing castable refractory for iron troughs, the usual method is to first weigh the raw materials according to the formula ratio and feed them into a mixing tank, then stir and mix them until uniformly blended before discharging. However, in actual batching and mixing, the mixing components of the agitators used are prone to damage and material adhesion, which significantly impacts the mixing efficiency and quality. Furthermore, conventional agitators are usually of a one-piece structure, making them inconvenient to disassemble, clean, and maintain when problems occur, resulting in a lack of flexibility and convenience in use, which needs improvement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a batching device for the production of iron trough castable, which sets the agitator into a split structure to facilitate disassembly and maintenance, thereby solving the above problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a batching device for producing castable refractory for iron troughs, comprising a batching tank, the top of which is open and abuts against a liftable tank cover, the edge of which is connected to a feed pipe with a feed valve, and the bottom of which is connected to a discharge pipe with a discharge valve. A drive mechanism is fixedly mounted in the center of the top surface of the tank cover. A stirrer is provided inside the batching tank, the stirrer comprising a stirring shaft and a bushing, the top end of which is rotatably connected to the center of the tank cover and passes through the tank cover and is coaxially fixedly connected to the downward-facing output end of the drive mechanism. A connecting sleeve is provided on the upper outer side of the stirring shaft, the top of which is closed and movably fitted onto the stirring shaft, and the bottom of which is open. The sleeve has internal threads on its opening and inner sidewalls. Arc-shaped slots are provided on both the left and right sides of the top of the connecting sleeve. A square positioning slot is provided at the center of the bottom of the stirring shaft. The top of the sleeve is open and the bottom is closed, with a square positioning block fixed at the center of the inner bottom. A limiting plate is fixedly sleeved on the upper part of the sleeve. External threads are provided on the outer side of the sleeve above the limiting plate. Inverted L-shaped limiting rods are rotatably provided on both the left and right sides of the limiting plate. The sleeve is inserted into the outside of the stirring shaft. The positioning block is inserted into the positioning slot. The connecting sleeve is screwed onto the upper outer side of the sleeve, and its bottom abuts against the limiting plate. The horizontal part of the limiting rod corresponds to the slot on the same side and rotates into the corresponding slot. A stirring assembly is provided on the outer side of the sleeve.

[0006] Preferably, vertical hydraulic cylinders are fixedly mounted on both the left and right outer sides of the mixing tank, with the piston rods of the hydraulic cylinders facing upwards and fixedly connected to the tank cover.

[0007] Preferably, there are several feed pipes distributed circumferentially at intervals on the edge of the can lid.

[0008] Preferably, the bushing is adapted to the stirring shaft.

[0009] Preferably, the positioning block is adapted to the positioning groove.

[0010] Preferably, the internal thread is adapted to the external thread.

[0011] Preferably, the limiting rod is adapted to the corresponding slot.

[0012] Preferably, the stirring assembly includes several square stirring frames fixedly connected to the outer periphery of the bushing and a turbine stirrer fixedly connected to the bottom of the bushing. Each stirring frame has a mesh stirring element formed by the intersection of several vertical rods and several horizontal rods fixedly on its inner side.

[0013] The beneficial effects of this utility model are as follows: When assembling the mixer, first slide the connecting sleeve onto the upper part of the mixing shaft, then insert the shaft sleeve onto the mixing shaft until the positioning block is inserted into the corresponding positioning groove. Then, control the connecting sleeve to rotate downwards, so that the connecting sleeve is screwed into the outer thread of the shaft sleeve through its internal thread until the connecting sleeve presses against the limiting plate and is tightened in place. The shaft sleeve can then be fixedly installed on the mixing shaft. Next, rotate the two limiting rods 180 degrees so that their horizontal parts are rotated into the corresponding slots, locking the connecting sleeve in place and restricting the axial movement of the connecting sleeve, thus completing the assembly of the mixer. Then, lower the tank cover until it abuts against the top of the mixing tank. Next, feed the corresponding material into the mixing tank through the feed pipe, then start the drive mechanism to drive the entire mixer to rotate. The mixing components on the shaft sleeve will mix and knead the material. After processing, the material can be discharged through the discharge pipe. After a period of use, the tank cover can be moved to a suitable height under no-load conditions. Then, rotate the limit rod to unscrew its horizontal part from the corresponding slot, releasing the lock on the connecting sleeve. Rotate the connecting sleeve upwards to unscrew it from the external thread of the bushing, releasing the screw connection to the bushing. Then, pull out the positioning block to remove the bushing from the stirring shaft. This facilitates cleaning and maintenance of the stirring components on the bushing. Afterward, reinstall the maintained bushing as described above, or install a new bushing as needed. In this way, the stirring shaft and bushing of the agitator are designed as separate, detachable structures. The bushing can be flexibly and conveniently removed from the stirring shaft for cleaning, maintenance, or replacement when needed. This makes the overall use more flexible and convenient, better ensuring stirring efficiency and quality, and making it more practical. Attached Figure Description

The edge of the tank cover 2 is connected to a feed pipe 4 with a feed valve 3, and the bottom of the batching tank 1 is connected to a discharge pipe 6 with a discharge valve 5. A drive mechanism 7 is fixedly installed in the center of the top surface of the tank cover 2. An agitator is installed inside the batching tank 1. The agitator includes a stirring shaft 8 and a bushing 9. The top end of the stirring shaft 8 is rotatably connected to the center of the tank cover 2, and this end passes through the tank cover 2 and is coaxially fixedly connected to the downward-facing output end of the drive mechanism 7. A connecting sleeve 10 is provided on the upper outer side of the stirring shaft 8. The top of the connecting sleeve 10 is closed and movably fitted onto the stirring shaft 8, the bottom is open, and the inner side wall is provided with internal threads 11. Arc-shaped slots 12 are opened on both the left and right sides of the top of the connecting sleeve 10, and a square positioning groove 13 is opened in the center of the bottom of the stirring shaft 8. The top of the bushing 9 is open, the bottom is closed, and a square positioning block 14 is fixedly installed at the center of the inner bottom. A limiting plate 15 is fixedly sleeved on the upper part of the bushing 9. An external thread 16 is provided on the outer side of the bushing 9 above the limiting plate 15. An inverted L-shaped limiting rod 17 is rotatably provided on both the left and right sides of the limiting plate 15. The bushing 9 is inserted into the outside of the stirring shaft 8. The positioning block 14 is inserted into the positioning groove 13.

The horizontal part of the limiting rod 17 corresponds to the corresponding groove 12 on the same side and rotates into the corresponding groove 12. A stirring assembly is provided on the outer side of the bushing 9. When assembling the mixer, first slide the connecting sleeve 10 onto the upper part of the mixing shaft 8, then insert the shaft sleeve 9 onto the mixing shaft 8 until the positioning block 14 is inserted into the corresponding positioning groove 13. Then, control the connecting sleeve 10 to rotate downwards, so that the connecting sleeve 10 is screwed into the external thread 16 of the shaft sleeve 9 through its internal thread 11 until the connecting sleeve 10 presses against the limiting plate 15 and is tightened in place. The shaft sleeve 9 can then be fixedly installed on the mixing shaft 8. Next, rotate the two limiting rods 17 180 degrees so that their horizontal parts are rotated into the corresponding slots 12, locking the connecting sleeve 10 in place and restricting its axial movement. This completes the assembly of the mixer. Then, lower the tank cover 2 until it abuts against the top of the mixing tank 1. Next, feed the corresponding material into the mixing tank 1 through the feed pipe 4, then start the drive mechanism 7 to drive the entire mixer to rotate. The mixing components on the shaft sleeve 9 will mix and knead the material. After processing, the material can be discharged through the discharge pipe 6. After a period of use, the tank cover 2 can be moved up to a suitable height under no-load conditions. Then, the limit rod 17 can be rotated to disengage its horizontal part from the corresponding slot 12, releasing the lock on the connecting sleeve 10. The connecting sleeve 10 can then be rotated upwards to unscrew it from the external thread 16 of the bushing 9, releasing the screw connection to the bushing 9. The positioning block 14 can then be pulled out to remove the bushing 9 from the stirring shaft 8, facilitating cleaning and maintenance of the stirring components on the bushing 9. Afterwards, the maintained bushing 9 can be reinstalled as described above, or a new bushing 9 can be installed as needed. In this way, the stirring shaft 8 and bushing 9 of the stirrer are designed as separate, detachable structures. When needed, the bushing 9 can be flexibly and conveniently disassembled from the stirring shaft 8 for cleaning, maintenance, or replacement. This makes the overall use more flexible and convenient, better ensuring stirring efficiency and quality, and making it more practical. The drive mechanism 7 can use existing conventional matching drive motors and other equipment.

The piston rods of the hydraulic cylinders 18 face upward and are fixedly connected to the tank cover 2. In actual use, the tank cover 2 can be raised and lowered by extending and retracting the piston rods of the hydraulic cylinders 18, so as to facilitate the disassembly of the agitator and convenient maintenance and replacement operations.

[0018] In this embodiment, there are several feed pipes 4 distributed circumferentially on the edge of the can lid 2 to facilitate the simultaneous feeding of multiple raw materials and improve the feeding rate.

[0019] In this embodiment, the bushing 9 is adapted to the stirring shaft 8 to ensure that the bushing 9 is smoothly inserted and installed in place.

[0020] In this embodiment, the positioning block 14 is adapted to the positioning groove 13 to ensure that the positioning block 14 is smoothly inserted into place.

[0022] In this embodiment, the limiting rod 17 is adapted to the corresponding slot 12 to ensure that the limiting rod 17 can be smoothly rotated into the slot 12, thereby achieving axial limiting of the connecting sleeve 10.

[0023] In this embodiment, the mixing assembly includes several square mixing frames 19 fixedly connected to the outer periphery of the bushing 9 and a turbine agitator 21 fixedly connected to the bottom of the bushing 9. Each mixing frame 19 has a mesh agitator 20 formed by the intersection of several vertical and horizontal bars fixedly installed on its inner side. This allows for efficient and high-quality mixing of materials during mixing and blending through the multiple mixing frames 19 and the mesh agitator 20 on each frame 19. This ensures both mixing strength and range, as well as material flowability, resulting in better mixing performance. Simultaneously, the turbine agitator 21 ensures effective mixing of materials at the bottom. Together, these components result in higher overall mixing efficiency and quality, better guaranteeing the processing quality of the castable refractory mix, making it more practical.
