Description

Technical Field

[0001] This utility model relates to the field of cylindrical screen technology, specifically a cylindrical screen for refractory material production. Background Technology

[0002] Cylindrical screens are commonly used screening equipment in the production of refractory materials. They are mainly used to classify materials by particle size to improve the uniformity and quality of the products. The working principle is that the rotating screen cylinder causes the material to roll inside. The material that meets the particle size requirements is discharged through the screen holes, while larger particles continue to be conveyed forward until they are discharged. Cylindrical screens have the characteristics of simple structure, large processing capacity and stable operation, and are widely used in refractory materials, metallurgy, chemical and other industries.

[0003] Since refractory materials may contain wet, sticky components or fine particles, they are prone to clogging the screen holes during screening, affecting screening efficiency. Traditional cleaning methods usually require stopping the machine and disassembling the screen cylinder for manual cleaning, which is not only cumbersome but also reduces production efficiency. In addition, mechanical cleaning alone is not enough to completely remove the fine particles attached to the screen holes, and long-term accumulation may lead to a decrease in screening effect. Therefore, we have proposed a cylindrical screen for refractory material production to solve the above-mentioned problems. Utility Model Content

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, the unblocking component is set up so that the gear meshes with the gear ring to control the rotation of the screen cylinder. When the screen hole rotates to the bottom of the unblocking rod, the bottom end of the unblocking rod will be inserted into the screen hole to push out the blockage inside the screen hole, thereby avoiding the blockage caused by the blockage that is difficult to clean.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example 1:

[0026] like Figure 1-4As shown, this utility model provides a technical solution: a cylindrical screen for refractory material production, including mounting plates 1. The mounting plates 1 are symmetrically arranged and fixedly connected to the screening machine. The mounting plates 1 are parts of the screening machine, facilitating the installation of the screen cylinder 2. The screen cylinder 2 is located inside the screening machine, thus facilitating the screening of materials. The material enters from one end of the screen cylinder 2, passes through the screen holes, and exits from the other end of the screen cylinder 2. During the screening process of the screen cylinder 2, the material may get stuck in the screen holes, or some wet material may adhere to the inside of the screen holes, causing blockage. The opposite sides of the mounting plates 1... A screen cylinder 2 is rotatably connected to the mounting plate 1. A clearing component 3 is provided on the opposite side of the mounting plate 1. The clearing component 3 includes clearing rods 301, which are arranged in a linear array for clearing the screen holes of the screen cylinder 2. The diameter of the clearing rods 301 is smaller than the inner diameter of the screen holes, which can clear the blockage in the screen holes and push the blockage back into the screen cylinder 2. The clearing rods 301 will not collide with the screen cylinder 2. Both ends of the screen cylinder 2 are fixedly connected to toothed rings 4, and the clearing component 3 controls the rotation of the toothed rings 4. A cleaning component 5 is fixedly connected on the opposite side of the mounting plate 1 for cleaning the surface of the screen cylinder 2, and the cleaning component 5 is movably connected to the toothed rings 4.

[0027] Example 2:

[0028] like Figure 1 and Figure 3 As shown, the unblocking component 3 also includes a rotating shaft 302, a cam 303, a control rod 304, a connecting frame 305, and a guide bar 306. The guide bar 306 is fixedly connected to the top of the connecting frame 305. The control rod 304 movably passes through the inner side of the connecting frame 305, and both ends of the control rod 304 are fixedly connected to the cam 303. The axis of the control rod 304 away from the cam 303 is fixedly connected to the rotating shaft 302 at the end of the cam 303 away from the control rod 304. The end of the rotating shaft 302 away from the cam 303 is connected to the mounting plate 1 via a bearing. The top of the unblocking rod 301 is fixedly connected to the bottom of the connecting frame 305. Gear 307 is fixedly connected to the outer side of the rotating shaft 302, and gear 307 meshes with the gear ring 4 respectively. The unblocking assembly 3 also includes a guide frame 308, which is fixedly connected to the opposite side of the mounting plate 1. A guide strip 306 passes through the guide frame 308 and is movably connected to the guide frame 308. A servo motor 6 is fixedly connected to the outer side of the mounting plate 1, and the output end of the servo motor 6 is fixedly connected to the end of the rotating shaft 302.

[0029] The servo motor 6 is started, driving the rotating shaft 302 to rotate, causing gear 307 and cam 303 to rotate synchronously. Since the control rod 304 is away from the axis of cam 303, the control rod 304 rotates around the axis of cam 303. Due to the movable engagement between the control rod 304 and the inner side of the connecting frame 305, and the guide frame 308 restricting the direction of movement of the guide bar 306, the longitudinal reciprocating movement of the connecting frame 305 is realized as the cam 303 rotates, thereby controlling the longitudinal reciprocating movement of the unblocking rod 301. Since gear 307 meshes with the gear ring 4, the screen cylinder 2 is rotated. When the screen hole rotates to below the unblocking rod 301, the bottom end of the unblocking rod 301 will insert into the inside of the screen hole, pushing out the blockage inside the screen hole, thereby avoiding the screen hole blockage caused by the blockage that is difficult to clean. Therefore, there is no need to remove the screen cylinder 2 for cleaning, which improves the cleaning efficiency of the screen cylinder 2 and ensures that the screen cylinder 2 can continue to work.

[0030] Example 3:

[0031] like Figure 1 and Figure 4 As shown, the cleaning assembly 5 includes a rotating rod 501, a cleaning wheel 502, a second gear 503, and a cleaning component. The rotating rod 501 passes through the cleaning wheel 502 and is fixedly connected to the cleaning wheel 502. Both ends of the rotating rod 501 are fixedly connected to the second gear 503, with the cleaning wheel 502 located on the opposite side of the second gear 503. The second gear 503 meshes with the gear ring 4. The cleaning component is fixedly connected to the opposite side of the mounting plate 1 and cleans the screen cylinder 2 using high-pressure gas. The cleaning component includes a cleaning section 504, a connecting section 505, and an air inlet section 506. The cleaning section 504 is symmetrically arranged. The cleaning wheel 502 is located on the opposite side of the cleaning wheel 502. The outlet end of the cleaning section 504 faces the surface of the screen cylinder 2. Both ends of the cleaning section 504 are fixedly connected to the connecting section 505, and the connecting section 505 is fixedly connected to the air inlet section 506. The interior of the cleaning section 504, the interior of the connecting section 505 and the interior of the air inlet section 506 are interconnected. The connecting section 505 is arc-shaped, and the gear 2 503 is located inside the connecting section 505. The cleaning wheel 502 is movably connected to the opposite side of the mounting plate 1 through the rotating rod 501, and the outer side of the cleaning wheel 502 is attached to the outer side of the screen cylinder 2.

[0032] The air inlet of the air inlet section 506 is connected to the air pipe, thereby introducing high-pressure gas into the interior of the connecting section 505. The high-pressure gas is blown out from the outlet of the cleaning section 504. The high-pressure gas will perform high-pressure cleaning on the surface of the screen cylinder 2 and the screen holes. In conjunction with the rotating cleaning wheel 502, it will clean the fine deposits inside the screen holes, effectively improving the cleaning effect.

[0033] Working principle: In use, firstly, the servo motor 6 is started, driving the rotating shaft 302 to rotate, causing gear 307 and cam 303 to rotate synchronously. Since the control rod 304 is away from the axis of cam 303, it rotates around the axis of cam 303. Because the control rod 304 is in movable engagement with the inner side of the connecting frame 305, and the guide frame 308 restricts the direction of movement of the guide strip 306, the longitudinal reciprocating movement of the connecting frame 305 is achieved as the cam 303 rotates, thereby controlling the longitudinal reciprocating movement of the unblocking rod 301. Since gear 307 meshes with the gear ring 4, the rotation of the screen cylinder 2 is controlled. When the screen hole rotates to below the unblocking rod 301, the bottom end of the unblocking rod 301 will insert into the inside of the screen hole, pushing out the blockage inside the screen hole, and the unblocking rod 301 will reset, and the unblocked screen hole will continue to rotate; since the gear ring 4 meshes with the gear 503, it drives the rotating rod 501 and the cleaning wheel 502 to rotate. The cleaning wheel 502 cleans the surface of the screen cylinder 2. The air inlet of the air inlet section 506 is connected to the air pipe, thereby introducing high-pressure gas into the inside of the connecting section 505, and the high-pressure gas is blown out from the outlet end of the cleaning section 504. The high-pressure gas will perform high-pressure cleaning on the surface of the screen cylinder 2 and the screen hole.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
