[0002] In cement production, iron separators are usually installed at the material inlet conveyor belt. They are effective at removing iron, and ferromagnetic metals mixed in are relatively easy to remove. However, high manganese steel, stainless steel, aluminum alloys, and large pieces of weakly magnetic or non-magnetic metals at the bottom of the conveyor belt are difficult for the iron separator to remove, which can easily cause equipment damage, affect equipment operation, and lead to frequent equipment failures. Summary of the Invention
[0003] The purpose of this application is to provide a metal separation device for cement production, which can solve the technical problem that large pieces of weakly magnetic or non-magnetic metals in the material fed into the mill are difficult to remove, which can easily cause equipment damage, affect equipment operation, and lead to frequent equipment failures.
[0004] This application provides a metal separation device for cement production, including a belt conveyor, a metal detector, a first discharge pipe, and a second discharge pipe. The metal detector is located above the belt conveyor. The first discharge pipe is located at the discharge end of the belt conveyor. The second discharge pipe is connected to the bottom of the first discharge pipe. A rotatable flap is provided between the first discharge pipe and the second discharge pipe. The flap can guide the material to the first discharge pipe or the second discharge pipe. A separation component for separating magnetic metal is provided inside the second discharge pipe.
[0005] The separation component includes a magnetic plate, which is embedded in the bottom of the second discharge pipe.
[0006] The second material discharge pipe is equipped with a scraping component, which is used to scrape off the magnetic metal attracted by the magnetic plate.
[0007] The scraping assembly includes a scraper, a screw, a motor, and a screw sleeve. The scraper is fitted to the bottom of the second material discharge pipe. A groove is provided on the inner wall of the second material discharge pipe. The screw is rotatably mounted in the groove via a bearing. The motor drives the screw to rotate. The screw sleeve is threaded onto the screw and is slidably connected to the groove. The scraper is fixedly connected to the screw sleeve.

[0012] The beneficial effects of this utility model are:
[0013] This utility model provides a metal separation device for cement production. In operation, materials are conveyed via a belt conveyor and then fall into a first discharge pipe for further transport. A metal detector detects the materials. When metal mixed in the materials passes through the metal detector, it transmits a signal to an external controller. At this point, a flap rotates to change the material flow direction, guiding the material and mixed metal into a second discharge pipe. Magnetic metals are then separated by a separation component, while non-magnetic metals are transported along the second discharge pipe to a collection device. The flap rotates again to change the material flow direction, allowing the material without metal to fall into the first discharge pipe for normal transport. This device, by incorporating a metal detector and a flap, can change the material flow direction when metal is detected, thereby separating the metal. This achieves automatic detection and efficient separation of metallic foreign objects in the material, preventing wear on subsequent equipment and reducing equipment failure rates. Furthermore, the separation component separates magnetic metals, facilitating the separate collection of magnetic and non-magnetic metals and simplifying the subsequent separation process.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] As shown in 1 and 2, this application provides a metal separation device for cement production, including a belt conveyor 1, a metal detector 2, a first discharge pipe 3, and a second discharge pipe 4. The metal detector 2 is located above the belt conveyor 1, the first discharge pipe 3 is located at the discharge end of the belt conveyor 1, and the second discharge pipe 4 is connected to the bottom of the first discharge pipe 3. A rotatable flap 5 is provided between the first discharge pipe 3 and the second discharge pipe 4. The flap 5 can guide the material to the first discharge pipe 3 or the second discharge pipe 4. A separation component 6 for separating magnetic metal is provided inside the second discharge pipe 4.
[0035] In use, the material is conveyed by the belt conveyor 1 and then falls into the first discharge pipe 3 for further conveying. The metal detector 2 detects the material. When metal mixed in the material passes through the metal detector 2, the metal detector 2 transmits a signal to the external controller. At this time, the flap 5 is rotated to change the flow direction of the material and guide the material and mixed metal into the second discharge pipe 4. Then, the magnetic metal is separated by the separation component 6, and the non-magnetic metal is conveyed along the second discharge pipe 4 to the collection device. Then, the flap 5 is rotated again to change the flow direction of the material, so that the material without mixed metal falls into the first discharge pipe 3 for normal conveying.
[0036] This device, by setting up a metal detector 2 and a flap 5, can change the flow direction of the material when metal is detected in the material, thereby separating the metal. It realizes automatic detection and efficient separation of metal foreign objects in the material, prevents metal foreign objects from causing wear to subsequent equipment, and reduces the equipment failure rate. The device also sets up a separation component 6 to separate magnetic metals, which facilitates the separate collection of magnetic and non-magnetic metals and simplifies the subsequent separation process.
[0037] like Figure 1 and 2 As shown, in this embodiment, the separation component 6 includes a magnetic plate 61, which is embedded in the bottom of the second discharge pipe 4. In use, the material and mixed metals flow into the second discharge pipe 4. The magnetic metals are magnetically attracted by the magnetic plate 61 and remain at the bottom of the second discharge pipe 4, thus separating the magnetic metals. The non-magnetic metals are then transported to the collection device along the second discharge pipe 4.
[0038] like Figure 1 and 2 As shown, in this embodiment, a scraper assembly 7 is provided inside the second material discharge pipe 4. The scraper assembly 7 is used to scrape off the magnetic metal adsorbed by the magnetic plate 61. The operator can periodically scrape off the magnetic metal adsorbed by the magnetic plate 61 and collect it according to the accumulation of magnetic metal. By setting the scraper assembly 7, this device realizes the automatic scraping off of the magnetic metal adsorbed on the magnetic plate 61, avoiding the tediousness of manual cleaning and improving the convenience of use.
[0039] like Figure 1 and 3 As shown, in this embodiment, the scraping assembly 7 includes a scraper 71, a screw 72, a motor 73, and a screw sleeve 74. The scraper 71 is fitted to the bottom of the second discharge pipe 4. The inner wall of the second discharge pipe 4 is provided with a groove 41. The screw 72 is rotatably mounted in the groove 41 through a bearing. The motor 73 drives the screw 72 to rotate. The screw sleeve 74 is threaded onto the screw 72 and is slidably connected to the groove 41. The scraper 71 and the screw sleeve 74 are fixedly connected.
[0040] When in use, the motor 73 is turned on to drive the screw 72 to rotate. The screw 72 drives the screw sleeve 74 to move. The screw sleeve 74 drives the scraper 71 to move. The moving scraper 71 scrapes off the magnetic metal attracted by the magnetic plate 61. The magnetic metal is then transported to the collection device along the second discharge pipe 4. The screw sleeve 74 and the chute 41 work together to guide and limit the scraper 71.
[0041] like Figure 1 and 2 As shown, in this embodiment, a baffle 42 is fixedly installed inside the second material discharge pipe 4; when the scraper assembly 7 is not running, the scraper 71 is in the initial position, and the baffle 42 can block the space above the scraper 71; the baffle 42 can prevent the material from falling above the scraper 71 and thus forming an accumulation when the material falls into the second material discharge pipe 4.
[0042] like Figure 1 and 2 As shown, in this embodiment, a rotating rod 8 is rotatably connected between the first material discharge pipe 3 and the second material discharge pipe 4 via a bearing, and a flap 5 is fixedly sleeved on the rotating rod 8. In use, the rotating rod 8 is rotated by turning on an external motor, and the rotating rod 8 drives the flap 5 to rotate to change the material flow direction.
[0043] like Figure 1 and 2 As shown, in this embodiment, a baffle 31 is fixedly installed inside the first discharge pipe 3, and the flap 5 can abut against the baffle 31. In use, the rotating rod 8 drives the flap 5 to rotate and change the material flow direction until the flap 5 abuts against the baffle 31. At this time, the stop block 42 can block the gap above the flap 5. The baffle 31 can prevent the material from flowing out from the gap above the flap 5 when the flap 5 rotates and changes the material flow direction, thereby ensuring that all the material and mixed metals flow to the second discharge pipe 4.
[0044] like Figure 1 and 2 As shown, in this embodiment, anti-collision components 9 are fixedly installed in the first material discharge pipe 3, the second material discharge pipe 4, and on the baffle 31, and the flap 5 can abut against the anti-collision components 9.
[0045] The anti-collision component 9 is made of rubber, which effectively prevents damage to the flap 5 caused by impact when switching guides, and extends its service life.
[0046] Working principle: When the metal separation device for cement production provided in this application is in use, the material is transported by the belt conveyor 1 and then falls into the first discharge pipe 3 for continued transport. The metal detector 2 detects the material. When metal mixed in the material passes through the metal detector 2, the metal detector 2 transmits a signal to the external controller. At this time, the external controller drives the external motor to rotate the rotating rod 8. The rotating rod 8 drives the flap 5 to rotate to change the material flow direction and guide the material and mixed metal into the second discharge pipe 4. Magnetic metal will be magnetically attracted by the magnetic plate 61 and stay at the bottom of the second discharge pipe 4, thus separating the magnetic metal. Non-magnetic metal is transported along the second discharge pipe 4 to the collection device. Then, the flap 5 is rotated again to change the material flow direction, so that the material without mixed metal falls into the first discharge pipe 3 for normal transport.
[0047] According to the accumulation of magnetic metal, the operator can periodically turn on the motor 73 to drive the screw 72 to rotate. The screw 72 drives the screw sleeve 74 to move, and the screw sleeve 74 drives the scraper 71 to move. The scraper 71 scrapes off the magnetic metal attracted by the magnetic plate 61. The magnetic metal is then transported to the collection equipment along the second discharge pipe 4.
[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
