Description

Technical Field

[0001] The utility model relates to the technical field of material screening, in particular to a high-density high-aluminum casting material screening device. Background Art

[0002] High-alumina castables are refractory castables made from high-alumina raw materials as aggregate and powder, with the addition of a binder. They possess high mechanical strength and excellent resistance to thermal shock and abrasion. They are primarily used as linings for various furnaces, including boilers, blast furnaces, heating furnaces, and ceramic kilns. Castable preparation requires screening of raw materials to achieve uniform particle size for optimal performance.

[0003] The filter structure of the current screening equipment is relatively simple. After the initial screening, the material needs to be taken out and placed in another device for more detailed screening. The process is relatively cumbersome, which affects the screening efficiency. In addition, the screening device currently used with the screen on the market is still a vibrating screen. This method uses a vibration motor to make the screen generate high-frequency vibration to assist in screening. However, in this vibration mode, the vibration range of the screen is small, and the tight materials stuck in the screen holes cannot escape, and the auxiliary screening effect is poor.

[0014] Preferably, the end of the top plate is rotatably connected to a roller that abuts against the outer convex plate, and the bottom surface of the outer convex plate is designed to be arc-shaped.

[0015] The beneficial effects are:

[0016] By placing the material to be screened inside the rectangular frame, the material is accumulated on the surface of the two layers of screen. Since the two layers of screen are staggered with each other, the screen holes are small. By controlling the vibration structure to drive the rectangular frame to vibrate back and forth in the vertical direction, smaller materials can fall from between the two layers of screen into the hopper for centralized collection.

Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 3 As shown, the utility model provides a high-density high-aluminum castable material screening device, including a rectangular frame 1, two screens 2 are detachably installed at the lower part of the rectangular frame 1, the screen 2 is composed of an outer frame 21 and a mesh body 22, and the mesh body 22 is located inside the outer frame 21 and is integrally formed therewith, and the two screens 2 are stacked, and a hopper 5 is provided below the rectangular frame 1, and the four lower corners of the hopper 5 are fixedly connected with support legs 11, and the four upper corners of the hopper 5 are provided with sliding connectors 4 for moving the rectangular frame 1 in the vertical direction, and both sides of the hopper 5 are provided with a vibration structure 3 for reciprocating the rectangular frame 1.

[0025] Reference Figure 3As shown, the four corners of the bottom of the rectangular frame 1 are fixedly connected with protrusions 6, and the upper surface of each protrusion 6 is fixedly connected with a positioning rod 7. The four corners of the outer frame 21 are provided with round holes 8 which are sleeved with the positioning rod 7. A magnetic block is provided inside the protrusion 6, and the protrusion 6 is magnetically connected to the iron outer frame 21. After the outer frame 21 is installed in the rectangular frame 1, the round hole 8 is sleeved on the positioning rod 7. At this time, the iron outer frame 21 is magnetically connected to the protrusion 6 with magnetic force. When the lower outer frame 21 is adsorbed with the protrusion 6, it also has magnetic force. At this time, the lower outer frame 21 is magnetically connected to the upper outer frame 21 to prevent the upper screen 2 from loosening during vibration.

[0026] Furthermore, handles 9 are fixedly connected to both sides of the upper surface of the lower outer frame 21, and grooves 10 adapted to the handles 9 are provided on both sides of the upper outer frame 21, so that the two screens 2 can be tightly abutted against each other. At the same time, the two screens 2 can be taken out at the same time by pulling up the handles 9, which is convenient and quick.

[0027] As an optional embodiment, the sliding connection 4 includes an ear plate 4a fixedly connected to the upper end of the hopper 5, the upper surface of the ear plate 4a is fixedly connected to the vertical shaft 4b, and the lower part of the outer wall of the rectangular frame 1 is fixedly connected to the sliding sleeve 4c mounted on the vertical shaft 4b, so that when the rectangular frame 1 moves up and down, the sliding sleeve 4c can slide up and down on the vertical shaft 4b, thereby making the rectangular frame 1 more stable and smooth when moving up and down.

[0028] Reference Figure 2 As shown, the vibration structure 3 includes a rotating shaft 3a rotatably connected to the inside of the aggregate hopper 5. The rotating shaft 3a is arranged in the middle along the length direction of the aggregate hopper 5. Both ends of the rotating shaft 3a extend out of the aggregate hopper 5 and are fixedly connected to a top plate 3b. A motor 3c for driving the rotating shaft 3a to rotate is fixedly installed on one side wall of the aggregate hopper 5. The middle part of the two side walls of the rectangular frame 1 is fixedly connected with an outer convex plate 3e adapted to the top plate 3b. The top plate 3b intermittently abuts against the outer convex plate 3e as the motor 3c rotates and drives the rectangular frame 1 to move upward. The end of the top plate 3b is rotatably connected to the outer convex plate 3e abuts against the matching roller 3d, and the bottom surface of the outer convex plate 3e is designed to be arc-shaped. When the motor 3c drives the rotating shaft 3a and the two top plates 3b to rotate, the rollers 3d at the ends of the two top plates 3b abut against the bottom surfaces of the outer convex plates 3e, and support the top rectangular frame 1 to move upward, while making the spring 4d elastically stretched. When the roller 3d is no longer in contact with the outer convex plate 3e, the rectangular frame 1 falls under the action of gravity and the elastic force of the spring 4d to complete the vibration. The arc-shaped design of the roller 3d and the bottom surface of the outer convex plate 3e can avoid wear when the roller 3d contacts the outer convex plate 3e, thereby improving the service life.

[0029] Furthermore, a spring 4d is connected between the ear plate 4a and the sliding sleeve 4c, and the spring 4d is sleeved on the outside of the vertical shaft 4b, which can enable the rectangular frame 1 to drive the materials on the surfaces of the two screens 2 to perform elastic shaking in the vertical direction, which can further enhance the vibration effect.

[0030] With the above structure, when in use, the material to be screened is placed inside the rectangular frame 1. At this time, the material is accumulated on the surface of the two layers of screen 2. Since the two layers of screen 2 are staggered with each other, the screen holes are small at this time. By controlling the vibration structure 3 to drive the rectangular frame 1 to vibrate back and forth in the vertical direction, smaller materials can fall from between the two layers of screen 2 into the collection hopper 5 for centralized collection. Then the upper filter 2 is removed. At this time, a single screen 2 is used for screening, the screen holes become larger, and larger materials will fall into the collection hopper 5 for centralized collection, completing the screening.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
