Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, and more specifically, to a mine wastewater filtration device. Background Technology

[0002] A mine wastewater filtration system is a device used to treat mine wastewater. Common types combine physical filtration and chemical adsorption, primarily removing impurities from the wastewater. Through multiple layers of filter screens, large particles are first intercepted, followed by the adsorption of fine particles and harmful substances, thus purifying the wastewater.

[0003] In existing mine wastewater treatment equipment, filtration is usually carried out from coarse to fine. However, mine wastewater contains a relatively large number of particulate impurities. When the wastewater is filtered through the filter screen installed inside the equipment, the filter screen is prone to clogging. At this time, it is necessary to stop the equipment operation and disassemble the filter screen for cleaning. However, frequent shutdowns for maintenance increase operating costs and also pose certain safety hazards. Utility Model Content

[0004] Based on the aforementioned technical problem that "when filtering sewage through the filter screen installed inside the device, the filter screen is prone to clogging frequently. At this time, it is necessary to stop the operation of the equipment and disassemble the filter screen for cleaning. However, frequent shutdowns for maintenance will increase operating costs and pose certain safety hazards," this utility model proposes a mine sewage filtration device.

[0005] The present invention discloses a mine wastewater filtration device, comprising a filter cylinder, a filter assembly, a lifting rod, a connecting plate, a sealing sleeve, a sealing gasket, and a drive assembly; the filter cylinder comprises an upper cylinder and a lower cylinder, the upper cylinder and the lower cylinder being arranged in an upper and lower structure, with a gap between the upper cylinder and the lower cylinder for impurity discharge;

[0006] The filter assembly includes a fixed sleeve and an elastic mesh fixedly connected within the fixed sleeve. The elastic mesh has a first form and a second form controlled by tension: in the first form, it forms a downwardly concave filter surface, and in the second form, it forms an upwardly convex impurity stripping surface.

[0007] The sealing sleeve is slidably connected to the inner wall of the upper cylinder; the sealing gasket is fixedly installed at the bottom of the sealing sleeve.

[0008] The connecting plate is fixedly installed on the inner wall of the sealing sleeve; the end of the rod passes through the connecting plate and is fixedly connected to it, and the bottom of the rod is fixedly connected to the elastic net.

[0009] The drive assembly is installed on the outer wall of the upper cylinder and is used to control the shape transformation of the elastic net.

[0010] Furthermore, the top of the upper cylinder is provided with a concentrically contracting conical guide section, and a water inlet pipe is welded to the top of the conical guide section.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] The mine wastewater filtration device of this utility model is suitable for coarse filtration of mine wastewater and can be used to filter larger particles of silt in wastewater, reducing the filtration burden on subsequent filtration equipment. The following are specific embodiments of this utility model;

[0028] like Figures 1-4 As shown, a mine wastewater filtration device includes a filter cartridge, a filter assembly, a boom 12, a connecting plate 13, a sealing sleeve 14, a sealing gasket 15, and a drive assembly.

[0029] The filter cartridge includes an upper cylinder 1 and a lower cylinder 3, which are arranged in an upper and lower structure. A gap is left between the upper cylinder 1 and the lower cylinder 3 for impurity discharge. The impurity discharge gap facilitates the discharge of impurities.

[0030] The filter assembly includes a fixed sleeve 17 and an elastic mesh 18 fixedly connected within the fixed sleeve 17. The elastic mesh 18 has a first form and a second form controlled by tension: in the first form, it forms a downwardly concave filter surface, and in the second form, it forms an upwardly convex impurity stripping surface. The elastic mesh 18 can switch forms to achieve filtration and impurity stripping functions, improve filtration efficiency, and facilitate cleaning.

[0031] The sealing sleeve 14 is slidably connected to the inner wall of the upper cylinder 1, the sealing gasket 15 is fixedly installed at the bottom of the sealing sleeve 14, and the connecting plate 13 is fixedly installed on the inner wall of the sealing sleeve 14. The arrangement of the sealing sleeve 14 and the sealing gasket 15 can prevent sewage leakage.

[0032] The end of the rod 12 passes through the connecting plate 13 and is fixedly connected to it, and the bottom of the rod 12 is fixedly connected to the elastic net 18;

[0033] The drive assembly is installed on the outer wall of the upper cylinder 1 and is used to control the shape transformation of the elastic net 18.

[0034] The elastic net 18 switches between the first and second states because, within the elastic limit, the deformation of the elastic net 18 is proportional to the external force applied. When the external force is removed, the elastic net 18 will return to its original state. When the elastic net 18 is forcibly bent, it is in the elastic deformation stage. The external force causes the elastic net 18 to generate elastic strain energy, which is stored inside the elastic net 18. When the external force disappears, the elastic strain energy is released and converted into the power for the elastic net 18 to return to its original state, causing it to automatically rebound.

[0035] like Figure 1 As shown, in some embodiments, the top of the upper cylinder 1 is provided with a concentrically contracting conical guide section, and a water inlet pipe 2 is welded to the top of the conical guide section.

[0036] The conical guide section at the top of the upper cylinder 1 allows sewage to flow in evenly, avoiding excessive local pressure that could affect the filtration effect, while also guiding the water flow more smoothly toward the elastic net 18.

[0037] like Figure 1 As shown, in some embodiments, the bottom of the lower cylinder 3 is provided with an inverted conical water collection hopper 4, and the bottom of the water collection hopper 4 is connected to the bottom end of the drain pipe 5 through a flange.

[0038] The inverted conical water collecting hopper 4 at the bottom of the lower cylinder 3 facilitates the collection of filtered water and allows the water to be discharged in a concentrated manner, reducing residue.

[0039] like Figure 2 and Figure 4 As shown, in some embodiments, the drive assembly includes a cylinder 8 fixedly mounted on the outer wall of the upper cylinder 1. The output end of the cylinder 8 passes through the upper cylinder 1 and extends into its interior. A support rod 9 is fixedly connected to the inner wall of the upper cylinder 1. A guide wheel 10 is rotatably connected to the inner wall of the support rod 9. A rope 11 is fixedly connected to the end of the cylinder 8. The bottom of the rope 11 is fixedly connected to the hanging rod 12.

[0040] The support rod 9 and guide wheel 10 can guide the rope 11 and reduce the rope 11 from deviating and wearing during the pulling process.

[0041] In some possible embodiments, a sealing ring is provided between the upper cylinder 1 and the sealing sleeve 14.

[0042] The sealing ring further enhances the sealing between the upper cylinder 1 and the sealing sleeve 14, preventing sewage from leaking from the gap between them and improving the reliability of the device.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments, the top of the lower cylinder 3 is provided with a first arc surface 16, and the top of the fixing sleeve 17 is provided with a second arc surface 19. The first arc surface 16 and the second arc surface 19 are tangent to each other, and the diameters of the first arc surface 16 and the second arc surface 19 decrease from top to bottom. The top surface formed by the elastic mesh 18 after it protrudes upward is tangent to the second arc surface 19.

[0044] The design of the first arc surface 16 and the second arc surface 19 being tangent and having decreasing diameters facilitates the discharge of impurities through the first arc surface 16 and the second arc surface 19.

[0045] like Figure 1 As shown, it also includes a support frame 7, and two mounting sleeves 6 are fixedly connected to the inner wall of the support frame 7. The upper mounting sleeve 6 is fixedly connected to the upper cylinder 1, and the lower mounting sleeve 6 is fixedly connected to the lower cylinder 3.

[0046] Working principle: Mine sewage enters the upper cylinder 1 through the inlet pipe 2. The sewage flows to the elastic net 18 for filtration. At this time, the elastic net 18 is in the first state, forming a downward concave filter surface. When the sewage passes through the elastic net 18, suspended solids and other impurities are intercepted in the downward concave filter surface. The filtered water flows into the water collection hopper 4 at the bottom of the lower cylinder 3 and is finally discharged through the drain pipe 5.

[0047] When it is necessary to clean the impurities on the elastic net 18, the cylinder 8 in the drive assembly is activated, the output end of the cylinder 8 retracts, and the rope 11 is pulled. The rope 11 drives the guide wheel 10 to roll, and at the same time drives the boom 12 to move upward. The boom 12 drives the connecting plate 13 fixed to it to move. The connecting plate 13 drives the sealing sleeve 14 to move. The sealing sleeve 14 slides upward along the inner wall of the upper cylinder 1. The boom 12 forcibly pulls the elastic net 18 upward to deform it elastically, so that it is transformed into the second form, forming an upwardly protruding impurity peeling surface. Under the force generated by the deformation of the elastic net 18 and its own gravity, the impurities are peeled off from the elastic net 18 and discharged along the gap between the upper cylinder 1 and the lower cylinder 3.

[0048] After cleaning, cylinder 8 extends, and at this time, elastic net 18 bends downward elastically, switching to the first form. The connecting plate 13 is moved by the hanging rod 12, which causes the connecting plate 13 to move the sealing sleeve 14 downward, so that the sealing gasket 15 at the bottom of the sealing sleeve 14 abuts against the top of the fixed sleeve 17, achieving a sealing effect.

[0049] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
