Description

Technical Field

[0001] This utility model relates to the field of underground mining technology, and in particular to a plastic frame filter. Background Technology

[0002] In in-situ leaching mining (such as uranium and copper mining), chemical solutions are injected into the underground ore layer to dissolve the target metal, and then the ore-bearing solution is extracted to the surface for treatment. In-situ leaching filters are typically installed in the well casing system of injection or extraction wells, mainly for: preventing wellbore blockage, protecting pumping equipment, and improving solution quality.

[0003] In related technologies, multiple outer filter rings of a ground-immersion filter are assembled together with positioning blocks and positioning grooves as needed. However, when the solution passes through the ground-immersion filter, the two filter rings are easily affected by the fluid and may float and separate, affecting the filtration effect, as well as the strength and rigidity of the ground-immersion filter. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a plastic frame filter that can improve its overall integrity, optimize the filtration effect, and ensure the strength and rigidity of the ground intrusion filter.

[0006] To achieve the above objectives, the first aspect of this utility model provides a plastic skeleton filter, comprising: a filter assembly, a plurality of positioning posts, a plurality of limiting posts, and a plurality of wire holes, wherein the filter assembly is arranged in a ring structure; the plurality of positioning posts are equidistantly disposed on the filter assembly, and the lower surface of the filter assembly is provided with a plurality of positioning holes equidistantly disposed opposite to the positioning posts; the plurality of limiting posts are equidistantly disposed on the filter assembly, and the height of the limiting posts is less than the height of the positioning posts; the plurality of wire holes are equidistantly disposed on the filter assembly.

[0007] In addition, the plastic frame filter proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the filter assembly includes an outer ring, an inner ring, and a plurality of protrusions. The outer ring is sleeved on the outside of the inner ring, and the inner wall of the inner ring is integrally formed with a plurality of protrusions. The plurality of protrusions are arranged at equal intervals and are directly opposite the positioning hole (21).

[0009] Specifically, the outer ring has two layers of filter channels, which are arranged alternately, and each layer has multiple filter channels.

[0010] Specifically, the height of the inner ring of the outer ring is equal to the height of the inner ring, the height of the outer ring of the outer ring is greater than the height of its inner ring, and an inclined surface is provided between the outer ring of the outer ring and the inner ring of the outer ring, the height difference of the inclined surface is less than or equal to half the height of the limiting column.

[0011] Specifically, the center of the wire hole is located on the inner ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: the plastic skeleton filter of the present invention can improve its integrity, optimize the filtration effect, and ensure the strength and rigidity of the ground intrusion filter.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following describes an embodiment of the plastic skeleton filter of this utility model with reference to the accompanying drawings.

[0021] like Figures 1-3As shown, the plastic skeleton filter of this utility model embodiment may include: 1. A plastic skeleton filter, characterized in that it includes: a filter assembly 1, a plurality of positioning posts 2, a plurality of spacing posts 3 and a plurality of wire holes 4.

[0022] The filter component 1 is arranged in a ring structure.

[0023] It should be noted that the filter assembly 1 is arranged in a ring structure, which can be adapted to the shape of the well casing system.

[0024] Multiple positioning posts 2 are equidistantly arranged on the filter assembly 1, and multiple positioning holes 21 are equidistantly opened on the lower surface of the filter assembly 1, which are arranged directly opposite to the positioning posts 2.

[0025] Multiple spacing posts 3 are equidistantly arranged on the filter assembly 1, and the height of the spacing posts 3 is less than the height of the positioning posts 2.

[0026] It is understandable that the height of the limiting post 3 is less than the height of the positioning post 2, which ensures that when the positioning post 2 is inserted into the positioning hole 21, the limiting post 3 does not come into contact with another plastic frame filter, thereby increasing the overall integrity of the multiple plastic frame filters assembled together.

[0027] Multiple wire holes 4 are equidistantly arranged on the filter assembly 1.

[0028] It should be noted that wires run through the inside of the wire hole 4, which can connect multiple plastic skeleton filters together, further increasing their overall integrity.

[0029] Specifically, in in-situ leaching mining (such as uranium and copper mining), this plastic skeleton filter is typically installed in the well casing system of injection or extraction wells.

[0030] First, outside the well, relevant technicians insert the positioning post 2 on one plastic skeleton filter into the positioning hole 21 of another plastic skeleton filter. At this time, the limiting post 3 on one plastic skeleton filter abuts against the other plastic skeleton filter, and the wire holes 4 of the two plastic skeleton filters are facing each other.

[0031] The relevant technicians used multiple wires to pass through multiple wire holes 4 one after another. After assembling multiple plastic skeleton filters together, the two ends of the wires were tied together to fix them. Finally, the ground intrusion filter was formed. After the assembly was completed, it was placed in the well pipe system using external hoisting equipment. The solution passed through the ground intrusion filter to block impurities (such as mud or rock debris), thereby preventing the well pipe or underground pores from being blocked and ensuring the efficiency of solution flow.

[0032] It should be noted that the quality of multiple plastic frame filters can be determined based on the depth of the well casing system and other data, and no specific limit is made here.

[0033] In the above embodiments, the positioning post 2 is inserted into the positioning hole 21, the limiting post 3 abuts against another plastic frame filter, and the implementation method of using multiple wires to pass through multiple wire holes 4 in succession can improve its integrity, avoid the floating and separation of two adjacent plastic frame filters, optimize the filtration effect, and ensure the strength and rigidity of the ground intrusion filter.

[0034] In one embodiment of this utility model, such as Figure 1 As shown, the filter assembly 1 includes an outer ring 11, an inner ring 12, and a plurality of protrusions 13.

[0035] The outer ring 11 is fitted on the outside of the inner ring 12. The inner wall of the inner ring 12 is integrally formed with multiple protrusions 13, which are equidistantly arranged and directly opposite the positioning hole 21.

[0036] It is understandable that placing the inner ring 12 inside the outer ring 11 can increase the strength and rigidity of the outer ring 11. Arranging the protrusion 13 inside the inner ring 12 can compensate for the opening of the positioning hole 21, ensuring the strength and rigidity of this plastic skeleton filter.

[0037] In one embodiment of this utility model, such as Figure 3 As shown, the outer ring 11 has two layers of filter channels 51, which are arranged alternately, and each layer of filter channels 51 has multiple channels.

[0038] Understandably, the staggered arrangement of the two filter channels 51 can optimize the filtration effect of the plastic frame filter.

[0039] It should be noted that the filter channel 51 described in this embodiment is not opened near the positioning hole 21 to avoid affecting the strength and rigidity of the outer ring 11.

[0040] In one embodiment of this utility model, such as Figure 3 As shown, the height of the inner ring of the outer ring 11 is equal to the height of the inner ring 12. The height of the outer ring of the outer ring 11 is greater than the height of its inner ring. An inclined surface 52 is provided between the outer ring of the outer ring 11 and the inner ring of the outer ring 11. The height difference of the inclined surface 52 is less than or equal to half the height of the limiting column 3.

[0041] It should be noted that the height difference of the inclined plane 52 described in this embodiment is less than half the height of the limiting column 3. That is, when the two plastic frame filters are assembled, the limiting column 3 on one plastic frame filter abuts against the other plastic frame filter, and there is a gap between the outer ring of the outer ring 11 of one plastic frame filter and the outer ring of the outer ring 11 of the other plastic frame filter. The width of the gap is equal to the difference between half the height of the limiting column 3 and the height difference of the inclined plane 52. The gap can be equal to the width of the filter channel 51, and it can also play a filtering role.

[0042] In another embodiment of this utility model, the height difference of the inclined plane 52 is equal to half the height of the limiting column 3. That is, when the two plastic skeleton filters are assembled, the limiting column 3 on one plastic skeleton filter abuts against the other plastic skeleton filter, and the outer ring of the outer ring 11 of one plastic skeleton filter abuts against the outer ring of the outer ring 11 of the other plastic skeleton filter, further improving its integrity and making the strength and rigidity of the entire ground intrusion filter further enhanced.

[0043] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the center of the wire hole 4 is located on the inner ring 12.

[0044] It is understandable that the center of the wire hole 4 is located on the inner ring 12, so that most of the wire hole 4 is opened on the inner ring 12, which can reduce the impact on the strength and rigidity of the outer ring 11.

[0045] In summary, the plastic frame filter of this utility model can improve its overall integrity, optimize the filtration effect, and ensure the strength and rigidity of the ground intrusion filter.
