Description

Technical Field

[0001] This utility model relates to the field of slurry equipment technology, and in particular to a pipeline iron removal device and a crusher. Background Technology

[0002] In the field of industrial material handling, electromagnetic separators, as key equipment for removing ferromagnetic impurities, are widely used to ensure the safety of production processes and product quality. Existing separators mainly consist of a shell, a magnetic circuit system, and a cleaning device. Their working principle is based on the magnetic field adsorption effect, and they are divided into two types: electromagnetic and permanent magnet. Electromagnetic separators achieve controllable magnetic field strength by adjusting the coil current, making them suitable for separating impurities of various particle sizes. Permanent magnet separators rely on permanent magnets to provide a stable magnetic field, featuring zero energy consumption and easy maintenance, but their magnetic field adjustment flexibility is insufficient. Both types of equipment play an important role in conventional conveyor belts or static material scenarios.

[0003] However, existing technologies exhibit significant limitations under the specific operating conditions of pipeline fluid media. The fluid within pipelines flows continuously, and the distribution of ferromagnetic impurities is transient, dispersed, and varies in particle size. Traditional magnetic separators, due to structural design limitations, struggle to adapt to the dynamic characteristics of the fluid: on the one hand, the high-speed movement of impurities with the fluid leads to a decrease in adsorption efficiency, and the matching degree between the magnetic field's effective area and the impurity's path is insufficient; on the other hand, continuous manual monitoring of the equipment's operating status and the distribution of impurities within the pipeline is required, increasing labor costs and posing safety hazards to operators and equipment maintenance due to the potential high temperature, high pressure, or corrosive environment of the fluid medium.

[0004] Therefore, how to improve the removal capacity of ferromagnetic impurities in pipeline fluid media is a technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline iron removal device and crusher to solve the problems existing in the prior art. By setting a magnet on the inner bottom surface of the box and setting the flow cross-sectional area of ​​the box to be larger than the area of ​​the inlet and outlet, the flow rate of the fluid entering the box can be slowed down, the magnet's adsorption capacity for ferromagnetic impurities can be improved, and finally the adsorbed ferromagnetic impurities can be removed from the iron removal outlet, thereby improving the removal capacity of ferromagnetic impurities in the pipeline fluid medium.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a pipeline iron removal device, including a box, a cover plate, and a magnet. The side wall of the box has an inlet, an outlet, and an iron removal outlet. The cross-sectional area of ​​the box is larger than the area of ​​the inlet and the area of ​​the outlet. The cover plate is used to block the iron removal outlet. The magnet is disposed on the inner bottom surface of the box, which is lower than the lowest point of the inlet and the lowest point of the outlet.

[0008] In one embodiment, the box is a rectangular box, the liquid inlet and the liquid outlet are respectively opened on one of a set of opposite sides of the box, and the ironware outlet is opened on one of the other set of opposite sides of the box.

[0026] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The purpose of this invention is to provide a pipeline iron removal device and crusher to solve the problems existing in the prior art. By setting a magnet on the inner bottom surface of the box and setting the flow cross-sectional area of ​​the box to be larger than the area of ​​the inlet and outlet, the flow rate of the fluid entering the box can be slowed down, the magnet's ability to adsorb and retain ferromagnetic impurities can be improved, and finally the adsorbed ferromagnetic impurities can be removed from the iron removal outlet, thereby improving the removal ability of ferromagnetic impurities in the pipeline fluid medium.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-5 As shown, this utility model provides a pipe iron removal device, including a housing 1, a cover plate, and a magnet 3. The side wall of the housing 1 has an inlet 11, an outlet 12, and an iron removal outlet 2. The housing 1 can be configured as a rectangular cylindrical structure, a circular cylindrical structure, or a composite structure (e.g., an arched shape with a flat bottom), allowing fluid to flow in through the inlet 11 and out through the outlet 12. The cross-sectional area of ​​the housing 1 is larger than the area of ​​the inlet 11 and larger than the area of ​​the outlet 12. That is, compared with the housing 1 and the pipe connected to it of the same length, the volume of fluid contained in the housing 1 is larger than the volume of fluid contained in the pipe. At this time, the flow rate of the fluid entering the housing 1 through the inlet 11 is slowed down. At the same time, the movement of ferromagnetic impurities is restricted when the fluid flows out of the housing 1 through the outlet 12. The cover plate is used to seal the iron removal outlet 2 to prevent leakage during fluid flow. When it is necessary to remove ferromagnetic impurities, the corresponding function can be accomplished by removing the cover plate. Magnets 3 are disposed on the inner bottom surface of the housing 1. They can be disposed separately or as a single piece. During installation, magnets 3 can be directly adsorbed onto the inner bottom surface of the housing 1, or clamping methods can be used to further improve the fixing effect. The inner bottom surface of the housing 1 is lower than the lowest point of the liquid inlet 11 and the lowest point of the liquid outlet 12. As a result, ferromagnetic impurities entering the liquid inlet 11 have a downward trend. Combined with the adsorption capacity of magnets 3, they can be better adsorbed onto magnets 3. At the same time, if the adsorbed ferromagnetic impurities need to flow out of the housing 1, they need to break free from the adsorption force of magnets 3 and have an upward force to overcome their own gravity. Therefore, the ability of ferromagnetic impurities to be stably adsorbed onto magnets 3 and kept inside the housing 1 is improved, thus improving the removal ability of ferromagnetic impurities.

[0030] This invention includes a magnet 3 inside the housing 1 and an iron removal port 2 on the housing 1. The magnet 3 can adsorb ferromagnetic impurities, and the iron removal port 2 can remove the ferromagnetic impurities. At the same time, the flow cross-sectional area of ​​the housing 1 is set to be larger than the area of ​​the inlet 11 and the outlet 12, which can slow down the flow rate of the fluid entering the housing 1, improve the adsorption and retention capacity of the magnet 3 for ferromagnetic impurities, and finally remove the adsorbed ferromagnetic impurities through the iron removal port 2, thereby improving the removal capacity of ferromagnetic impurities in the pipeline fluid medium.

[0031] In one embodiment, the housing 1 is a rectangular housing with a top surface, a bottom surface, and four sides. The four sides are arranged in pairs opposite each other. The inlet 11 and outlet 12 are respectively located on one pair of opposite sides of the housing 1, and the ironware outlet 2 is located on one of the other pair of opposite sides of the housing 1. The ironware outlet 2 can be located on one side, two sides, or, in another example, on the top surface. The placement of the ironware outlet 2 facilitates the removal of ferromagnetic impurities without affecting the inflow and outflow of fluid.

[0032] In one embodiment, the inlet 11 and the outlet 12 are coaxially arranged, and the area of ​​the inlet 11 is equal to the area of ​​the outlet 12. In this case, the projections of the inlet 11 and the outlet 12 in the vertical plane can be consistent, which is beneficial to the flow of fluid and reduces the obstruction to the flow of fluid. At the same time, it is also convenient for the selection and application of materials for the pipes connecting the housing 1.

[0033] In one embodiment, the magnets 3 are evenly spaced in a matrix on the inner bottom surface of the housing 1, with gaps between them. This facilitates fluid flow and creates space for ferromagnetic impurities. The magnets 3 can be strong, permanent magnets that require minimal maintenance. In other examples, electromagnets can be used to adjust the magnetic force.

[0034] In one embodiment, the bottom of the magnet 3 is 50mm to 70mm from the bottom of the pipeline (the lowest position of the inlet 11 or the lowest position of the outlet 12). In this example, 58mm is selected, which can effectively store ferromagnetic impurities without causing salt to form and reduce the adsorption force of the magnet 3.

[0035] In one embodiment, the flow cross-sectional area of ​​the housing 1 is 1.5 to 2.5 times the area of ​​the inlet 11. In this example, a pipeline iron removal device is installed 10 meters in front of the crusher, and the flow cross-sectional area of ​​the housing 1 is 1.99 times the area of ​​the inlet 11 to reduce the slurry flow rate, allowing the magnet 3 sufficient time to adsorb ferromagnetic impurities. Specific dimensions are as follows:

[0036] Volume of box 1: V1 = 0.6m × 0.6m × 0.8m = 0.288m 3 ;

[0037] The volume of pipes of the same length: V² = 0.241m × 0.241m × 3.14m × 0.8m = 0.145m 3 ;

[0038] The ratio of the cross-sectional area of ​​the flow passage of the housing 1 to the area of ​​the liquid inlet 11 is: V1 / V2 = 0.288 / 0.145 = 1.99.

[0039] In one embodiment, the top surface of the magnet 3 is lower than the lowest point of the liquid inlet 11 and the lowest point of the liquid outlet 12. That is, the position of the magnet 3 in the box 1 is relatively low. After the magnet 3 is installed on the bottom surface of the box 1, its top height will not exceed the lowest point of the liquid inlet 11 and the liquid outlet 12. The magnet 3 is in a recessed space, which can better adsorb and store ferromagnetic impurities.

[0040] In one embodiment, the ironware outlet 2 is provided with a flange, which has through holes or threaded holes in the circumferential direction. After the cover plate is connected to the flange, it is fastened by bolts and screws. In addition, a sealing gasket can be provided between the cover plate and the flange to ensure the sealing performance after the cover plate is installed.

[0041] To ensure the adsorption capacity of the pipeline iron removal device, the cover is opened periodically to remove the adsorbed ferromagnetic impurities. In this example, the cover is opened every 10 days to clean the adsorbed ferromagnetic impurities and prevent excessive blockage of the housing 1 by ferromagnetic impurities.

[0042] Refer again Figures 1-5 As shown, this utility model provides a crusher, including a crusher body and a pipeline iron removal device as described above. The outlet 12 on the housing 1 is connected to the inlet of the crusher body. After the ferromagnetic impurities in the slurry are adsorbed and removed by the pipeline iron removal device, the slurry enters the crusher body again. The pipeline iron removal device can improve the removal effect of ferromagnetic impurities and ensure the smooth operation of the crusher body.

[0043] In one embodiment, the system also includes an inlet pipe 4 and an outlet pipe 5. One end of the inlet pipe 4 is connected to the liquid inlet 11, and the outlet of the inlet pipe 4 is connected to the pump body or the slurry tank. One end of the outlet pipe 5 is connected to the liquid outlet 12, and the other end of the outlet pipe 5 is connected to the inlet of the crusher body. The other end of the outlet pipe 5 is higher than the first end of the outlet pipe 5. That is to say, after the ferromagnetic impurities are removed by the pipeline iron removal device, the slurry will rise along the outlet pipe 5 until it reaches the inlet of the crusher body. Since the ferromagnetic impurities have a higher density and weight than the slurry, this rising process can effectively prevent the adsorbed ferromagnetic impurities from detaching from the magnet 3 and being washed away by the slurry.

[0044] In one embodiment, the other end of the outlet pipe 5 is higher than the first end of the outlet pipe 5 by more than 1m. In this example, the rear pipeline of the pipe iron removal device (i.e., the outlet pipe 5) is raised by 3 meters. This setting makes it difficult for most of the adsorbed ferromagnetic impurities to detach from the magnet 3 and be washed away by the slurry.

[0045] The present invention provides specific embodiments as follows:

[0046] 1. Weld box 1 in the processing plant. Box 1 is made of 10mm thick steel plate. A DN450 seamless steel pipe with a length of 150mm is welded to the side as iron outlet 2. A DN450 flange is welded on the seamless steel pipe. A DN450 flange blind plate (i.e. cover plate) is made and connected to the flange with M27*80 bolts.

[0047] 2. At a position 10 meters in front of the main body of the crusher and 3 meters down, cut off the original pipeline at the original location, and then weld the iron separator of box 1 to the pipeline.

[0048] 3. Open the cover, place magnet 3 on the inner bottom surface of box 1, and install the cover.

[0049] 4. After running for 10 days, open the cover and remove the adsorbed ferromagnetic impurities.

[0050] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
