Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral admixture preparation technology, and in particular to a mineral admixture conveying pipeline type iron removal device. Background Technology
[0002] Mineral admixtures are active auxiliary cementitious materials added to concrete to replace a portion of cement clinker. Since the production of cement clinker consumes significant amounts of energy and emits large amounts of carbon dioxide, the application of mineral admixtures can reduce the amount of cement clinker used, thus helping to reduce carbon emissions and energy consumption. Simultaneously, it enables the resource utilization of industrial solid waste, reducing pollution to the environment and organisms. Mineral admixtures are made from industrial solid waste such as steel slag, mineral slag, natural zeolite, and silica fume. During production, the raw materials need to be initially crushed and then ground in a grinding mill to improve the cementitious activity of the mineral admixtures. Because these raw materials typically undergo multiple mechanical processes, they may contain impurities formed from broken or detached iron parts, which can easily cause excessive wear on the grinding discs when entering the grinding mill. Therefore, iron impurities need to be removed before the mineral admixture raw materials are fed into the grinding mill. The currently used pipeline-type iron separator requires stopping the material transport after a certain period of use, removing the iron separator from the pipeline to clean the iron impurities adsorbed on it, and then reinstalling the iron separator back into the pipeline. This process is complicated, time-consuming, and inefficient. Utility Model Content
[0003] This invention provides a pipeline-type iron removal device for mineral admixtures, which can clean adsorbed iron impurities without removing the iron remover from the pipeline, thus improving production efficiency. Specifically, the technical solution of this invention is as follows.
[0004] A mineral admixture conveying pipeline type iron removal device includes: an iron removal pipeline, a discharge pipeline, an electromagnetic iron separator, a waste discharge pipe, and a first valve. The iron removal pipeline is inclined, and its upper sidewall has a top surface interface, with the lower port of the discharge pipeline communicating with this top surface interface. The electromagnetic iron separator is inserted into the upper port of the iron removal pipeline and seals the upper port. The waste discharge pipe is vertically arranged on the bottom surface of the sidewall of the iron removal pipeline and located behind the electromagnetic iron separator. The first valve is located on the waste discharge pipe to control its opening and closing.
[0005] Furthermore, the iron removal pipe is inclined at an angle of 40 to 50° relative to the horizontal plane.
[0006] Furthermore, it also includes a collection box, with the lower end of the iron removal pipe connected to the inlet on the collection box. The collection box is equipped with two sets of iron removal devices formed by the aforementioned iron removal pipe, discharge pipe, electromagnetic iron separator, waste discharge pipe, and first valve, and the upper end of the discharge pipe of both sets of iron removal devices is connected to the lower end of the conveying pipe.
[0007] Furthermore, a second valve is provided on the upper end side wall of the feeding pipe of both sets of iron removal devices to control the opening and closing of the feeding pipe.
[0008] Furthermore, the electromagnetic separator includes a flange cover and a tubular electromagnet. The tubular electromagnet is vertically fixed to the inner surface of the flange cover, which covers the upper end of the iron removal pipe, and the two are detachably and fixedly connected. The tubular electromagnet is located inside the iron removal pipe cavity, and the two are parallel.
[0009] Furthermore, a vibrator is fixed to the outer surface of the side wall of the non-iron pipe to promote the flow of material in the pipe.
[0010] Compared with the prior art, this utility model has the following beneficial technical effects: The mineral admixture conveying pipeline iron removal device adopts an electromagnetic iron separator inclinedly installed in the iron removal pipeline. When the mineral admixture to be ground passes through the electromagnetic iron separator, iron impurities in it can be adsorbed and separated from the mineral admixture. When the electromagnetic iron separator needs to be cleaned after a certain period of use, the power supply to the electromagnetic iron separator is turned off, allowing the adsorbed iron impurities to automatically fall off and slide onto the bottom surface of the inner wall of the iron removal pipeline, then be discharged through the discharge pipe. Thus, the adsorbed iron impurities can be cleaned without removing the electromagnetic iron separator from the pipeline, which helps to reduce operation steps and improve production efficiency.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. For ease of description, if the words "up," "down," "left," and "right" appear in the present utility model, they only indicate that they are consistent with the up, down, left, and right directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the present utility model and simplifying the description, and therefore should not be construed as specific limitations on the present utility model.
[0016] refer to Figure 1 An example of a mineral admixture conveying pipeline type iron removal device includes: an iron removal pipeline 1, a discharge pipeline 2, an electromagnetic iron separator 3, a waste discharge pipe 4, and a first valve 5. Specifically, the iron removal pipeline 1 is inclined, and its inclination angle relative to the horizontal plane can be arbitrarily selected between 40° and 50°, such as 40°, 45°, 50°, etc., to facilitate the downward movement of the mineral admixture to be ground entering the iron removal pipeline 1. Other suitable inclination angles can also be selected as needed. The upper sidewall of the iron removal pipeline 1 has a top surface interface 6, and the lower port of the discharge pipeline 2 is vertical and communicates with the top surface interface 6 to convey the mineral admixture to be ground into the iron removal pipeline 1.
[0017] The electromagnetic separator 3 is inserted into the inner cavity of the iron removal pipe 1 from its upper port, as detailed in the following reference. Figure 2The electromagnetic separator 3 includes a flange cover 301 and a tubular electromagnet 302. The tubular electromagnet 302 is vertically fixed to the inner surface of the flange cover 301, which covers the upper port flange of the iron removal pipe 1, and the two are detachably fixed together by bolts or other fasteners. The tubular electromagnet 302 is located within the inner cavity of the iron removal pipe 1 and is parallel to it, thus utilizing the inner space of the iron removal pipe 1 to accommodate a longer tubular electromagnet 302, increasing the contact area between the admixture and the tubular electromagnet 302, and improving the iron removal effect. The wire of the tubular electromagnet 302 extends through the flange cover 301 to the outside of the upper port of the iron removal pipe 1. When energized, the tubular electromagnet 302 generates a magnetic attraction effect; when the power is disconnected, the magnetic attraction effect disappears. The number of tubular electromagnets 302 can be one or multiple, depending on actual needs, such as the diameter of the iron removal pipe 1 and the particle size of the admixture. Meanwhile, the magnetic strength can be controlled by changing the power of the tubular electromagnet 302, thereby improving the iron removal effect.
[0018] The discharge pipe 4 is vertically arranged on the bottom side wall of the iron removal pipe 1 and located behind the electromagnetic separator 3. The discharge pipe 4 is connected to the inner cavity of the iron removal pipe 1. The first valve 5 is installed in the discharge pipe 4 to control its opening and closing. In use, the mineral admixture to be ground enters the iron removal pipe 1 through the feed pipe 2 and the top interface 6, and then slides down through the tubular electromagnet 302. If the mineral admixture contains iron impurities, they will be adsorbed on the outer wall of the tubular electromagnet 302, thereby separating the iron impurities from the mineral admixture. The separated mineral admixture is discharged from the lower port of the iron removal pipe 1. When the electromagnetic separator 3 needs to be cleaned after a certain period of use, the feeding of the mineral admixture is stopped, and then the first valve 5 is opened to discharge the admixture deposited in the discharge pipe 4. Then, the power supply to the electromagnetic separator 3 is disconnected. The adsorbed iron impurities automatically fall off and land on the bottom inner wall of the iron removal pipe 1, and then slide down to the discharge pipe 4 for discharge. Thus, the adsorbed iron impurities can be cleaned without removing the electromagnetic separator 3 from the pipe, reducing the number of operation steps and improving production efficiency.
[0019] In another embodiment, the aforementioned mineral admixture conveying pipeline iron removal device consists of two sets, and the device further includes a collection box 7. Specifically, refer to... Figure 1The collection box 7 is located below the lower port of the iron removal pipe 1. The top surface of the collection box 7 has a feed inlet 8, which is connected to the lower port of the iron removal pipe 1. The mineral admixture, after iron removal, is discharged from the lower port of the iron removal pipe 1 and enters the collection box 7. The collection box 7 is equipped with two sets of iron removal devices formed by the aforementioned iron removal pipe 1, discharge pipe 2, electromagnetic iron separator 3, impurity discharge pipe 4, and first valve 5. The upper ends of the discharge pipes 2 of both sets of iron removal devices are connected to the lower end of the conveying pipe 9. A second valve 10 is installed on the side wall of the upper port of the discharge pipes 2 of both sets of iron removal devices to control the opening and closing of the discharge pipes 2.
[0020] The iron removal device of this embodiment can achieve uninterrupted iron removal from mineral admixtures. In use, one set of the iron removal devices (such as...) Figure 1 The iron removal device on the left side is in an inactive state, and its corresponding second valve 10 is closed. The mineral admixture in the conveying pipe 9 flows into the iron removal device on the right side for iron removal. When the electromagnetic separator 3 needs cleaning after a certain period of use, the iron removal device on the left side and its second valve 10 are opened, and then the iron removal device on the right side and its second valve 10 are closed. The electromagnetic separator 3 is then cleaned according to the above method. Therefore, the conveying of the mineral admixture does not need to be stopped during the cleaning of the electromagnetic separator 3. By ensuring that one of the two sets of iron removal devices is always in standby mode and by switching between the two sets, the impact on production during the cleaning of the electromagnetic separator 3 can be effectively avoided.
[0021] In another implementation, refer to Figure 1 In the aforementioned mineral admixture conveying pipeline type iron removal device, a vibrator 11 is fixed to the outer surface of the side wall of the iron removal pipeline 1. This not only helps to promote the flow of material in the pipeline or to clear the blockage of the iron removal pipeline 1, but also helps iron debris that falls onto the bottom surface of the inner wall of the iron removal pipeline 1 to slide downwards and be discharged from the discharge pipe 4. Additionally, a vibrator can also be installed on the outer wall of the discharge pipeline 2 to clear the blockage of the discharge pipeline 2 and promote material discharge.
[0022] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
