Description

Technical Field

[0001] This application relates to the field of mining equipment, and more specifically to a protective component suitable for an emulsification pressurization filtration device. Background Technology

[0002] Emulsification booster filtration devices are widely used in hydraulic systems of coal mine pump stations, commonly found in hydraulic operation scenarios such as coal mine support emulsion pump station systems, coal mine spray pump station systems, and coal mine fracturing pump station systems. This device typically consists of three main parts: a filter, a centrifugal pump, and a motor. The filter removes impurities from the liquid, ensuring the purity of the liquid entering the emulsification pump, thereby reducing wear on the pump and subsequent equipment. The centrifugal pump achieves efficient liquid delivery through pressurization, while the motor provides the driving force.

[0003] In existing technologies, emulsifying pressurized filtration devices need to be frequently moved and transported underground due to factors such as the progress of coal seam mining. Typically, the emulsifying pressurized filtration device is fixed to a support base. During transport, the support base moves together with the emulsifying pressurized filtration device. The centrifugal pump is usually fixed to the support base at the bottom, while the motor is mounted on top of the centrifugal pump, away from the support base. Due to the complex underground transport environment, the equipment is frequently subjected to shaking and vibration during transport, and may also tilt. This shaking, vibration, and tilting can cause significant stress at the connection between the centrifugal pump and the motor, thus affecting the stability and reliability of the device. In particular, as the motor power increases, the weight of the motor also increases accordingly. Since the motor is usually mounted on top of the centrifugal pump, and its center of gravity is relatively high, this high center of gravity design makes it more susceptible to shaking and tilting during transport, further exacerbating the stress at the connection and posing a risk of damage. Utility Model Content

[0004] Therefore, this application provides a protective component suitable for emulsifying pressurized filtration devices to solve the problem in the prior art that the connection between the centrifugal pump and the motor may be damaged due to shaking, vibration and tilting during transportation.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A protective component is provided for an emulsifying pressurized filtration device, the emulsifying pressurized filtration device including a filter, a centrifugal pump connected to the filter, and a motor connected to the centrifugal pump. The protective component includes a support base and a protective member connected to the support base. The filter is connected to one side of the support base, the centrifugal pump is connected to the other side of the support base away from the filter, the motor is located on the top of the centrifugal pump away from the support base, and the protective member is supported on the periphery of the motor.

[0007] Optionally, the protective component includes two support parts respectively connected to the support base, two first limiting rods and two second limiting rods. The two ends of the first limiting rods are respectively connected to the top of the two support parts, and the two first limiting rods are respectively located on both sides of the motor. The two ends of the second limiting rods are respectively connected to the two first limiting rods, and the two second limiting rods abut against both sides of the motor.

[0008] The support portion includes two third limiting rods with one end connected to the support base and a first support plate connected between the two third limiting rods. The two ends of the first limiting rod are respectively connected to the two third limiting rods of the support portion, and the two third limiting rods and the two first limiting rods correspond one-to-one.

[0009] Optionally, the first limiting rod, the second limiting rod, and the third limiting rod are all channel steel. The first limiting rod and the third limiting rod are connected by a first bolt. The third limiting rod has a first elongated hole at its web plate that matches the first bolt. A first positioning plate is connected between the two wing plates of the third limiting rod. The first positioning plate has a first through hole that matches the first bolt. The end of the first limiting rod is connected to a second positioning plate. The second positioning plate has a first threaded hole that matches the first elongated hole and the first bolt.

[0010] The first limiting rod and the second limiting rod are connected by a second bolt. The first limiting rod has a second elongated hole on the wing plate near the second limiting rod that matches the second bolt. The other wing plate of the first limiting rod has a second through hole that matches the second bolt. The end of the second limiting rod is connected to a third positioning plate. The third positioning plate has a second threaded hole that matches the second elongated hole and the second bolt.

[0011] Optionally, the side of the second limiting rod closest to the motor is connected to a flexible pad for abutting against the motor.

[0012] Optionally, a fourth positioning plate is connected to the end of the third limiting rod away from the first limiting rod. The fourth positioning plate is connected to the support base by a third bolt, and a reinforcing rib is connected between the web of the third limiting rod and the fourth positioning plate.

[0013] Optionally, the support base includes two I-beams, with multiple second support plates connected between the two I-beams, a third limiting rod connected to the I-beams, and the two I-beams corresponding one-to-one with the two third limiting rods. The filter is connected to the second support plate on one side of the support base, and the centrifugal pump is connected to the second support plate on the other side of the support base.

[0014] Optionally, the support base is connected to a plurality of lifting rings for use with lifting equipment.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] When the emulsifying booster filter unit needs to be transported as a whole, it is connected to the support base and moved as a whole. The support base is the load-bearing structure of the emulsifying booster filter unit, connecting and supporting various components such as the filter, centrifugal pump, and motor. Protective components are installed around the motor, working in conjunction with the support base to provide support and protection for the motor, especially during transportation. The protective components effectively buffer and disperse external forces generated during transportation, preventing these forces from acting directly on the motor and its connection with the centrifugal pump. Through the supporting function of the protective components, the risk of tipping due to the high center of gravity of the motor is reduced, while stress concentration at the motor and centrifugal pump connection points is reduced due to swaying and vibration, thus effectively preventing problems such as loosening, deformation, or damage to connecting components.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0032] refer to Figure 1-4This application discloses a protective component suitable for an emulsification pressurization filtration device. The emulsification pressurization filtration device includes a filter 3, a centrifugal pump 4 connected to the filter 3, and a motor 5 connected to the centrifugal pump 4. The protective component includes a support base 1 and a protective member 2 connected to the support base 1. The filter 3 is connected to one side of the support base 1, the centrifugal pump 4 is connected to the other side of the support base 1 away from the filter 3, the motor 5 is located on the top of the centrifugal pump 4 away from the support base 1, and the protective member 2 is supported on the periphery of the motor 5.

[0033] When the emulsifying and pressurizing filter unit needs to be transported as a whole, it is connected to the support base 1 and moved as a whole. The support base 1 is the load-bearing structure of the emulsifying and pressurizing filter unit, connecting and supporting various components such as the filter 3, centrifugal pump 4, and motor 5. The protective component 2 is installed around the motor 5, working in conjunction with the support base 1 to provide support and protection for the motor 5, especially during transportation. The protective component 2 can effectively buffer and disperse external forces generated during transportation, preventing these forces from acting directly on the motor 5 and its connection with the centrifugal pump 4. Through the supporting function of the protective component 2, the risk of tipping over due to the high center of gravity design of the motor 5 can be reduced, while reducing stress concentration at the connection points of the motor 5 and centrifugal pump 4 caused by shaking and vibration, thereby effectively preventing problems such as loosening, deformation, or damage to the connecting components.

[0034] refer to Figure 4-5 The protective component 2 includes two support parts 21 respectively connected to the support base 1, two first limiting rods 22 and two second limiting rods 23. The two ends of the first limiting rods 22 are respectively connected to the top of the two support parts 21, and the two first limiting rods 22 are respectively located on both sides of the motor 5. The two ends of the second limiting rods 23 are respectively connected to the two first limiting rods 22, and the two second limiting rods 23 abut against both sides of the motor 5.

[0035] The support part 21 includes two third limiting rods 211 connected at one end to the support base 1 and a first support plate 212 connected between the two third limiting rods 211. The two ends of the first limiting rod 22 are respectively connected to the third limiting rods 211 of the two support parts 21, and the two third limiting rods 211 and the two first limiting rods 22 correspond one-to-one.

[0036] Two second limiting rods 23 abut against both sides of the motor 5, providing lateral support and limiting lateral displacement caused by shaking or vibration during transportation. Two first limiting rods 22 are connected to the top of the two support parts 21, forming a support frame around the motor 5 together with the second limiting rods 23. In some embodiments, the first limiting rods 22 may also abut directly against both sides of the motor 5, working together with the second limiting rods 23 to support and limit the motor 5 around its perimeter, reducing offset and shaking of the motor 5 during transportation.

[0037] In some other embodiments, the emulsifying pressurized filter device may have two centrifugal pumps 4 and corresponding motors 5, with both centrifugal pumps 4 connected to the filter 3. In this way, two second limiting rods 23 can be set on the basis of the above structure to abut and limit the motors 5.

[0038] refer to Figure 7-10 The first limiting rod 22, the second limiting rod 23, and the third limiting rod 211 are all channel steel. The first limiting rod 22 and the third limiting rod 211 are connected by the first bolt 215. The third limiting rod 211 has a first elongated hole 2111 at its web to fit the first bolt 215. The third limiting rod 211 is connected to a first positioning plate 216 between its two wing plates. The first positioning plate 216 has a first through hole 2161 to fit the first bolt 215. The end of the first limiting rod 22 is connected to the second positioning plate 221. The second positioning plate 221 has a first threaded hole 2211 to fit the first elongated hole 2111 and the first bolt 215.

[0039] The first limiting rod 22 and the second limiting rod 23 are connected by the second bolt 224. The wing plate of the first limiting rod 22 near the second limiting rod 23 has a second elongated hole 222 that matches the second bolt 224. The other wing plate of the first limiting rod 22 has a second through hole 223 that matches the second bolt 224. The end of the second limiting rod 23 is connected to the third positioning plate 231. The third positioning plate 231 has a second threaded hole 2311 that matches the second elongated hole 222 and the second bolt 224.

[0040] The protective assembly allows for adjustment of the distance between the first limiting rod 22 and the second limiting rod 23 to accommodate the dimensional requirements of motors 5 with different power ratings. When the motor 5 needs to be replaced with a higher or lower power model, the distance between the two first limiting rods 22 and the distance between the two second limiting rods 23 can be flexibly changed by adjusting the position of the bolts. Specifically, when it is necessary to adjust the distance between the two first limiting rods 22, the first bolt 215 connecting the first limiting rod 22 and the third limiting rod 211 can be loosened. Using the sliding space provided by the first elongated hole 2111, the position of the first bolt 215 in the first elongated hole 2111 can be adjusted so that the distance between the two first limiting rods 22 matches the width of the motor 5. Subsequently, the first bolt 215 is tightened, its threaded end is connected to the first threaded hole 2211, and the nut of the first bolt 215 is pressed against the first positioning plate 216, thereby fixing the adjusted position of the first limiting rod 22.

[0041] Similarly, when it is necessary to adjust the distance between the two second limiting rods 23 to accommodate the motor 5, the second bolt 224 connecting the first limiting rod 22 and the second limiting rod 23 can be loosened, and the position of the second bolt 224 can be adjusted through the sliding space provided by the second elongated hole 222. After the adjustment is completed, the second bolt 224 is tightened so that its threaded end is connected to the second threaded hole 2311, and the nut of the second bolt 224 is tightly pressed against the wing plate of the first limiting rod 22 with the second through hole 223, thereby fixing the position of the second limiting rod 23.

[0042] This design allows the protective assembly to quickly adapt to the installation requirements of motors 5 of different sizes, which not only simplifies installation and adjustment operations but also reduces the need for large-scale modifications to the entire protective assembly structure when replacing motors 5.

[0043] The shapes of the first through hole 2161 and the first elongated hole 2111 are adapted to each other, and the shapes of the second through hole 223 and the second elongated hole 222 are adapted to each other.

[0044] It should be noted that channel steel is existing technology, and channel steel has a web and flanges located on both sides of the web.

[0045] The second limiting rod 23 has a flexible pad connected to the side near the motor 5 for abutting against the motor 5.

[0046] The flexible pad is installed on the side of the second limit rod 23 near the motor 5 to form a buffer layer between the protective component and the motor 5, avoiding wear or impact caused by hard contact.

[0047] In some embodiments, the flexible pad may be a rubber pad.

[0048] refer to Figure 5-6 The end of the third limiting rod 211 away from the first limiting rod 22 is connected to the fourth positioning plate 213. The fourth positioning plate 213 is connected to the support base 1 by the third bolt. A reinforcing rib 214 is connected between the web of the third limiting rod 211 and the fourth positioning plate 213.

[0049] The reinforcing rib 214 is set between the web of the third limiting rod 211 and the fourth positioning plate 213. Its main function is to improve the connection strength between the third limiting rod 211 and the fourth positioning plate 213 and the overall structural rigidity.

[0050] The support base 1 includes two I-beams 11, and multiple second support plates 12 are connected between the two I-beams 11. A third limiting rod 211 is connected to the I-beams 11, and the two I-beams 11 correspond one-to-one with the two third limiting rods 211. The filter 3 is connected to the second support plate 12 on one side of the support base 1, and the centrifugal pump 4 is connected to the second support plate 12 on the other side of the support base 1.

[0051] The support base 1 is connected to multiple second support plates 12 via two I-beams 11 to form an integral structure. The number of second support plates 12 can be flexibly set according to the size and weight of the filter 3 and centrifugal pump 4, thereby ensuring that the filter 3 and centrifugal pump 4 can obtain sufficient support area to distribute the pressure of their weight on the support base 1.

[0052] The support base 1 is connected to multiple lifting rings 6 for use with lifting equipment.

[0053] Multiple lifting rings 6 are provided on the support base 1 to cooperate with lifting equipment, enabling convenient handling and installation of the emulsification pressurization filter device. The lifting rings 6 are evenly distributed at different positions on the support base 1, and through connection with lifting equipment (such as cranes, winches, etc.), the entire device can be lifted smoothly.

[0054] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0055] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
