Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation equipment, in particular to a slag removal structure of a magnetic separator. Background Art

[0002] In carbon black production, magnetic separator is a kind of magnetic separation equipment that uses magnetic rods to absorb ferromagnetic impurities in materials and remove the impurities. Magnetic separator has the advantages of compact structure, simple and reliable, and not easy to block materials. The existing magnetic separator uses a three-way flap valve mechanism to switch the channel between the discharge port and the slag port. See the attached manual for details. Figure 3 , 4 . When the material falls, the flap valve opens the material port and closes the slag port; when the slag is to be removed, the material stops falling, and the flap valve flips to open the slag port and close the material port. The biggest disadvantage of using a three-way flap valve is that the flap valve has poor sealing and is prone to leakage. Especially when used for extremely fine carbon black powder, it is difficult for the three-way flap valve to seal the carbon black powder tightly, and a large amount of powder leaks to the slag port, causing material waste; when removing slag, it is also easy to cause impurities to leak into the finished material, and when removing slag, the slag falls naturally, and some of the slag will adhere to the magnetic rod or around the flap valve, resulting in incomplete slag removal.

DETAILED DESCRIPTION

[0029] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0030] The present invention provides a slag removal structure of a magnetic separator, including a material dropping channel 10 and a slag removal channel 20. Figure 1 , 2 The two ends of the hollow barrel 11 are connected to form a blanking channel 10. One end of the barrel 11 is a feed port 111, the other end is a discharge port 113, and the middle part is a processing chamber 112. The slag removal channel 20 is located on one side of the processing chamber 112. A second mounting barrel 21 is fixed on the side of the processing chamber 112 through the side wall of the barrel 11. The second mounting barrel 21 is hollow and one end is closed and the other end is open. The open end is fixed on the outer wall of the barrel 11 and communicates with the processing chamber 112.

[0031] A slag collecting structure 3 is arranged between the material dropping channel 10 and the slag removal channel 20, and a sealing valve 25 is arranged at the output end of the slag removal channel 20, which is equivalent to arranging a sealing valve 25 at the slag material outlet, see Figure 1 , 2 , the sealing valve 25 is arranged on the second mounting cylinder 21;

[0032] The slag collecting structure 3 comprises:

[0033] The slag collecting rod 31 includes a magnetic portion 311 located in the material dropping channel 10 and a non-magnetic portion 312 located in the slag removing channel 20;

[0034] and a slag cleaning plate 32, a sealing sleeve is arranged on the slag collecting rod 31, and can move between a first position and a second position along the axial direction of the slag collecting rod 31;

[0035] When the slag cleaning plate 32 is located at the first position, it is in the blanking state, the blanking channel 10 and the slag removal channel 20 are located on the same side of the slag cleaning plate 32, and the sealing valve 25 is closed; the material enters the blanking channel 10 from the feed inlet 111 and is transmitted along the blanking channel 10. When passing through the processing chamber 112, the ferromagnetic impurities in the material are adsorbed by the magnetic part 311 of the slag collecting rod 31 located in the blanking channel 10. At this time, since the output end of the slag removal channel 20 is closed by the sealing valve 25 with strong sealing performance, the adsorbed material is only transmitted along the blanking channel 10. When it reaches the discharge port 113, the material is the finished product material after impurities are removed, which can avoid the waste of material caused by the large amount of powdery finished material leaking to the slag material port;

[0036] When the adsorption amount of the magnetic part 311 is large, the material dropping is stopped. At this time, the slag cleaning plate 32 is moved along the axial direction of the slag collecting rod 31, so that the slag cleaning plate 32 moves from the first position to the second position. During the process, the slag cleaning plate 32 scrapes off the ferromagnetic impurities adsorbed by the magnetic part 311 and pushes it close to the non-magnetic part 312. Since the sealing sleeve of the slag cleaning plate 32 is arranged on the slag collecting rod 31, on the one hand, it can ensure that the scraping process is clean and thorough, and on the other hand, it can ensure that the slag cleaning plate 32 seals and separates the two sides of the slag collecting rod 31;

[0037] When the slag cleaning plate 32 is located at the second position, the material delivery channel 10 and the slag removal channel 20 are sealed and separated by the slag cleaning plate 32, a slag collecting chamber 211 is formed in the second mounting cylinder 21, and the sealing valve 25 is opened to enter the slag removal state. At this time, the ferromagnetic impurities are separated from the adsorption of the magnetic part 311 and enter the slag collecting chamber 211 of the slag removal channel 20, and are output from the output end of the slag removal channel 20 through the opened sealing valve 25. Since the slag removal channel 20 and the material delivery channel 10 are sealed and separated by the slag cleaning plate 32, negative pressure or purging operations can be assisted to completely remove the impurities, and the impurities will not leak into the finished material at all.

[0038] In one preferred embodiment, an air inlet pipe 24 is provided at the input end of the slag removal channel 20. Figure 1 , 2 , an air inlet pipe 24 is connected to the top of the second mounting cylinder 21. In the blanking state, the air inlet pipe 24 is closed. When the slag cleaning plate 32 separates the blanking channel 10 from the slag removal channel 20, the sealing valve 25 is opened first, and then the air inlet pipe 24 is opened and air is blown into the slag removal channel 20 through the air inlet pipe 24. Impurities in the slag removal channel 20 can be quickly discharged. The slag is removed by blowing, which is convenient for centralized collection of impurities at the output end of the slag removal channel 20. The layout is reasonable. Preferably, the sealing valve 25 is externally connected to the slag discharge pipe 26 to realize centralized collection of impurities. After the slag removal is completed, the blowing is stopped and the air inlet pipe 24 and the sealing valve 25 are closed in turn, and the slag cleaning plate 32 can be moved back to the first position, which is easy to operate.

[0039] In one of the preferred embodiments, a plurality of slag collecting rods 31 are provided, and the plurality of slag collecting rods 31 are arranged at intervals. The plurality of slag collecting rods 31 arranged at intervals can improve the adsorption effect of ferromagnetic impurities and ensure that the material passes through the blanking channel 10 smoothly in the blanking state.

[0040] In one preferred embodiment, the slag collecting rod 31 is perpendicular to the center line of the material dropping channel 10, and the slag collecting structure 3 further includes:

[0041] A first circular plate 35 is located in the slag removal channel 20, and a plurality of slag collecting rods 31 are fixed at one side edge of the first circular plate 35 in a circumferential array;

[0042] The first rotating rod 38 is arranged on the other side of the first circular plate 35, and its axis is colinear with the axis of the circular array of the plurality of slag collecting rods 31. Figure 1 , 2 The first rotating rod 38 and the closed end of the second connecting tube 21 are rotatably matched to realize the overall support of the slag collecting structure 3 and facilitate the application of force to the second rotating rod 38, which is the case of application to a rotor magnetic separator; in the blanking state, the first rotating rod 38 is driven to drive the first circular plate 35 to rotate.

[0043] In the blanking state, when the first rotating rod 38 is driven to rotate the first circular plate 35, the slag collecting rod 31 rotating with the first circular plate 35 can break up the material passing through the blanking channel 10, so as to improve the cleaning effect of ferromagnetic impurities. At the same time, the slag collecting rod 31 rotates with the first circular plate 35 to ensure the uniformity of contact between several slag collecting rods 31 and the material, thereby further improving the adsorption efficiency of ferromagnetic impurities. Preferably, the magnetic part 311 extends to the edge of the blanking channel 10 to ensure the adsorption area of ​​the magnetic part 311, thereby further improving the cleaning effect of ferromagnetic impurities.

[0044] In one preferred embodiment, the slag collecting structure 3 further comprises:

[0045] A second circular plate 36, one side of which is fixedly connected to the ends of the plurality of slag collecting rods 31 away from the non-magnetic portion 312;

[0046] The second rotating rod 39 is disposed on the other side of the second circular plate 36 , and the axis thereof is colinear with the axis of the first rotating rod 31 .

[0047] The second circular plate 36 and the second rotating rod 39 can ensure the overall smooth rotation of the slag collecting structure 3 and maintain the balance of both ends of the slag collecting rod 31. In addition, when the slag cleaning plate 32 moves along the axial direction of the slag collecting rod 31, since the two ends of the slag collecting rod 31 are respectively fixed by the first circular plate 35 and the second circular plate 36, the slag cleaning plate 32 can be smoothly translated.

[0048] A first mounting cylinder 12 is fixed on the other side of the processing chamber 112 and passes through the side wall of the barrel 11. The first mounting cylinder 12 is hollow and has one end that is closed and the other end that is open. The open end is fixed on the outer wall of the barrel 11 and is connected to the processing chamber 112. In order to facilitate the installation of the second circular plate 36 and prevent the second circular plate 36 from interfering with the magnetic part 311 in removing impurities from the material passing through the blanking channel 10, the first mounting cylinder 12 is arranged on the side of the outer wall of the barrel 11 opposite to the second mounting cylinder 21. At the same time, the second rotating rod 39 is rotatably matched with the closed end of the first mounting cylinder 12 to support the second rotating rod 39, thereby further ensuring the stability of the slag collecting structure 3 during rotation.

[0049] In one of the preferred embodiments, the slag collecting structure 3 also includes a translation rod 37 that is movable along the axis of the second rotating rod 39 and passes through the second rotating rod 39, that is, the second rotating rod 39 is a hollow rod, and one end of the translation rod 37 is fixedly connected to the slag cleaning plate 32, so as to facilitate the application of force to the slag cleaning plate 32, so that the slag cleaning plate 32 moves between the first position and the second position along the axis direction of the slag collecting rod 31.

[0050] In one of the preferred embodiments, a sealing sleeve 32 is provided between the slag collecting rod 31 and the slag cleaning plate 32 to ensure the sealing effect of the slag cleaning plate 32 sleeved on the slag collecting rod 31, and the structure is simple.

[0051] In one of the preferred embodiments, a sealing ring 34 is provided on one side of the slag cleaning plate 32. The sealing ring 34 is located on the outside of the slag collecting rod 31. The sealing ring 34 is located on the side close to the slag removal channel 20, so as to realize the sealed partition of the slag cleaning plate 32 to the material delivery channel 10 and the slag removal channel 20. The structure is simple, the construction is convenient, the materials are convenient to obtain, and the maintenance cost is low.

[0052] In one of the preferred embodiments, the center line of the material dropping channel 10 is along the vertical direction, and the slag removal channel 20 is located on one side of the material dropping channel 10. When dropping materials, the materials pass through the material dropping channel 10 under the action of their own gravity, and there is no need to add an additional structure to drive the materials through the material dropping channel 10, thereby simplifying the structure. In addition, the slag removal channel 20 is located on one side of the material dropping channel 10, and the free-falling materials will not fall into the slag removal channel 20. The layout is reasonable. Furthermore, in order to avoid or reduce the splashing of materials into the slag removal channel 20 when passing through the material dropping channel 10, the outer diameter of the material feeding channel is smaller than the material dropping channel 10, and the material is fed along the center line of the material dropping channel 10, or along the side away from the slag removal channel 20.

[0053] In one of the preferred embodiments, a baffle 22 is arranged between the material dropping channel 10 and the slag removal channel 20 to further avoid or reduce splashing of materials into the slag removal channel 20 when passing through the material dropping channel 10. A through hole 23 matching the slag cleaning plate 32 is opened in the middle of the baffle 22, and the slag collecting rod 31 passes through the through hole 23; when the slag cleaning plate 32 is in the second position, the slag cleaning plate 32 closes the through hole 23. The slag cleaning plate 32 only needs to close the through hole 23 to achieve a sealed partition between the material dropping channel 10 and the slag removal channel 20, thereby reducing the size of the slag cleaning plate 32, especially when the slag cleaning plate 32 rotates with the slag collecting rod 31, so as to ensure smooth operation and greatly reduce the energy consumption of the equipment.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
