Description

Technical Field

[0001] This utility model belongs to the field of coal mine dust removal and environmental protection technology, specifically relating to an online magnetization enhancement device for coal mine dust reduction water. Background Technology

[0002] Coal mine dust is one of the major hazards faced during coal mining, seriously threatening the physical and mental health of underground workers and the safe production of enterprises. While traditional water spray dust suppression methods are widely used, their dust suppression effect is poor, especially for small-particle, highly hydrophobic respirable dust. Therefore, developing efficient water magnetization devices to improve the wetting properties of aqueous solutions and enhance dust suppression efficiency is of great significance for coal mine dust control.

Journal of Coal Science and Technology, 2021, 46(12):3891-3901 [1] Zhou Qun. Research on active magnetized water dust suppression mechanism and technology in coal mines [D]. China University of Mining and Technology, 2019, etc., introduced the application of magnetization devices in the preparation of dust suppression liquid in coal mines. The dust suppression effect varies depending on the magnetization rate of the dust suppression liquid used in the actual coal production process. However, the cost of adding a magnetization device to improve the magnetization effect based on the magnetization technology disclosed in the existing literature is relatively high, and the consumption is not commensurate with the output. However, if the internal structure of the magnetization device is improved, the magnetization effect of the dust suppression liquid can be significantly improved at a lower cost, thereby improving the dust suppression effect. Utility Model Content

[0004] In order to solve the above-mentioned technical problems in the prior art, this utility model provides an online magnetization and efficiency enhancement device for coal mine dust suppression water that is connected to a high-pressure water pipe, has a simple structure, low cost, and good magnetization effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an online magnetization efficiency enhancement device for coal mine dust suppression water, including an outer tube, the center line of which is set along the left and right direction, and a left flange and a right flange respectively connected to the left and right ends of the outer tube. An outer magnetization cylinder assembly is coaxially arranged inside the outer tube, and an inner magnetization cylinder assembly is coaxially arranged inside the outer magnetization cylinder assembly. The left and right ends of the inner magnetization cylinder assembly are connected to the inner circles of the left flange and the right flange respectively. An annular water passage is provided between the inner circle of the outer magnetization cylinder assembly and the outer circle of the inner magnetization cylinder assembly, and a number of spirally spaced baffles are provided in the annular water passage.

[0006] The outer magnetized cylinder assembly includes an outer cylinder, with its left and right ends connected to a left flange and a right flange, respectively. Several cylindrical external magnets are installed in the outer annular cavity formed between the outer circle of the outer cylinder and the inner circle of the outer sleeve.

[0007] The inner magnetized cylinder assembly includes an inner cylinder, inside which are coaxially arranged several inner magnets, each cylindrical in shape. The number of outer magnets and inner magnets are the same and arranged in a one-to-one correspondence. The magnetic poles of the inner magnets and outer magnets are opposite, and the magnetic poles of two adjacent outer magnets are opposite. The left and right ends of the inner cylinder are respectively connected to a left connecting plate and a right connecting plate, both circular in shape. The outer circle of the left connecting plate is fixedly connected to the inner circle of the left flange, and the outer circle of the right connecting plate is fixedly connected to the inner circle of the right flange. The outer circle of the inner cylinder and the inner circle of the outer cylinder form the aforementioned annular water passage. Several water passage holes communicating with the annular water passage are opened on both the left and right connecting plates.

[0008] Each spoiler is fan-shaped and fixedly connected to the outer circle of the inner cylinder. The angle between each spoiler and the center line of the inner cylinder is acute, and each spoiler has small water-permeable holes.

[0009] The distance between any two adjacent spoilers along the axial direction of the inner cylinder is equal, and the central angle formed by any two adjacent spoilers along the circumference of the inner cylinder is equal.

[0010] Compared with the prior art, the working principle and technical effects of this utility model using the above technical solution are as follows:

[0011] 1) This utility model connects to the high-pressure water pipe for dust removal in coal mines via a left flange and a right flange. The annular water passage is connected to the inside of the high-pressure water pipe through a water passage hole. The inner and outer magnets, which are arranged correspondingly, have opposite magnetic poles (along the radial direction of the outer cylinder). When the high-pressure water in the high-pressure water pipe enters the annular water passage, the magnetic field lines generated between the inner and outer magnets magnetize the water flow. Since the magnetic poles of two adjacent outer magnets are also opposite (along the radial direction of the outer cylinder), the magnetization direction can be alternated between the inside and outside, thus improving the magnetization effect.

[0012] 2) Several baffles are spirally arranged inside the annular water passage. As the high-pressure water flows through the passage, it is guided by the baffles, continuously generating turbulent flows in different directions. These turbulent flows create a pressure difference between the left and right ends of the annular water passage, causing the high-pressure water to form turbulence within the passage. This turbulence further mixes and homogenizes the magnetized water, increasing its magnetization rate. In contrast, ordinary magnetization devices only increase the magnetization area and magnetization rate through a spiral structure. The baffles have permeable holes, allowing water to pass through, thus creating turbulent flows in different directions after the high-pressure water is blocked, guided, and permeated by the baffles.

[0013] 3) The left and right connecting plates connect to the left and right flanges respectively, serving to seal the inner cylinder. The water passage hole connects to the high-pressure water pipe.

[0014] 4) The left and right flanges serve to seal the outer cylinder and connect with the flange on the high-pressure water pipe through a sealing gasket.

[0015] In summary, this utility model has a scientific principle and a simple structure. By setting up an annular water passage, the dust removal water is magnetized by the combined action of the inner and outer magnets during the online transportation process, which agitates the dust removal water and forms a turbulent flow to fully improve the magnetization effect and ultimately achieve the purpose of improving the dust removal effect.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] like Figures 1-6As shown, this utility model discloses an online magnetization efficiency enhancement device for coal mine dust suppression water, including an outer sleeve 1. The center line of the outer sleeve 1 is arranged in the left-right direction. The left and right ends of the outer sleeve 1 are respectively connected to a left flange 2 and a right flange 3. An outer magnetization cylinder assembly is coaxially arranged inside the outer sleeve 1. An inner magnetization cylinder assembly is coaxially arranged inside the outer magnetization cylinder assembly. The left and right ends of the inner magnetization cylinder assembly are respectively connected to the inner circles of the left flange 2 and the right flange 3. An annular water passage 4 is provided between the inner circle of the outer magnetization cylinder assembly and the outer circle of the inner magnetization cylinder assembly. Several spirally spaced baffles 5 are provided in the annular water passage 4.

[0024] The outer magnetized cylinder assembly includes an outer cylinder 6, with the left and right ends of the outer cylinder 6 connected to the left flange 2 and the right flange 3 respectively. Several cylindrical external magnets 8 are installed in the outer annular cavity 7 formed between the outer circle of the outer cylinder 6 and the inner circle of the outer sleeve 1.

[0025] The inner magnetized cylinder assembly includes an inner cylinder 9. Inside the inner cylinder 9, several cylindrical inner magnets 10 are coaxially arranged. The number of outer magnets 8 and inner magnets 10 is the same and they are arranged in a one-to-one correspondence. The magnetic poles of the inner magnets 10 and outer magnets 8 are opposite. The magnetic poles of two adjacent outer magnets 8 are opposite. The left and right ends of the inner cylinder 9 are respectively connected to a circular left connecting plate 11 and a circular right connecting plate 12. The outer circle of the left connecting plate 11 is fixedly connected to the inner circle of the left flange 2, and the outer circle of the right connecting plate 12 is fixedly connected to the inner circle of the right flange 3. The annular water passage 4 is formed between the outer circle of the inner cylinder 9 and the inner circle of the outer cylinder 6. Several water passage holes 13 communicating with the annular water passage 4 are opened on the left connecting plate 11 and the right connecting plate 12.

[0026] Each spoiler 5 is fan-shaped and fixedly connected to the outer circle of the inner cylinder 9. The outer circle of the spoiler 5 is in contact with the inner circle of the outer cylinder 6. The angle between each spoiler 5 and the center line of the inner cylinder 9 is acute. Each spoiler 5 is provided with a water-permeable hole 14.

[0027] The distance between any two adjacent spoilers 5 along the axial direction of the inner cylinder 9 is equal, and the central angle formed by any two adjacent spoilers 5 along the circumferential direction of the inner cylinder 9 is equal.

[0028] The working principle and technical effects of this utility model are as follows:

[0029] 1) This utility model connects to the high-pressure water pipe for dust removal in coal mines via the left flange 2 and the right flange 3. The annular water passage 4 communicates with the inside of the high-pressure water pipe through the water passage hole 13. The inner magnet 10 and the outer magnet 8, which are arranged correspondingly inside and outside, have opposite magnetic poles (in the radial direction of the outer cylinder 6). When the high-pressure water in the high-pressure water pipe enters the annular water passage 4, the magnetic field lines generated between the inner magnet 10 and the outer magnet 8 magnetize the water flow. Since the magnetic poles of the two adjacent outer magnets 8 are also opposite (in the radial direction of the outer cylinder 6), the magnetization direction can be alternated inside and outside, thus improving the magnetization effect. Figure 4 The arrows in the diagram indicate the direction of the magnetic field lines.

[0030] 2) Several baffles 5 are spirally arranged inside the annular water passage 4. When the high-pressure water flows through the annular water passage 4, it is guided by the baffles 5, continuously generating swirling turbulence in different directions. The swirling turbulence causes a pressure difference between the left and right ends of the annular water passage 4. Due to the pressure difference, the high-pressure water forms turbulence in the annular water passage 4. The turbulence further mixes the magnetized water evenly, increasing the magnetization rate. In contrast, ordinary magnetization devices only increase the magnetization area and improve the magnetization rate through a spiral structure. The baffles 5 are provided with water-permeable holes 14, which allow water to pass through, thus forming swirling turbulence in different directions after the high-pressure water is blocked, guided, and permeated by the baffles 5.

[0031] 3) The left connecting plate 11 and the right connecting plate 12 are connected to the left flange 2 and the right flange 3 respectively, serving to seal the inner cylinder 9. The water passage hole 13 serves to connect to the high-pressure water pipe.

[0032] 4) The left flange 2 and the right flange 3 serve to seal the outer cylinder 6, and at the same time, they are connected to the flange installed on the high-pressure water pipe through a sealing gasket.

[0033] The above embodiments illustrate the basic principles and features of this utility model. However, the above descriptions are merely preferred embodiments and are not limited to these embodiments. Those skilled in the art, inspired by this patent, can make many modifications and improvements without departing from the spirit and scope of the claims, all of which fall within the protection scope of this utility model. Therefore, the patent and its scope of protection should be determined by the appended claims.
