Description

Technical Field

[0001] This utility model belongs to the technical field of interference bed sorting machines, specifically relating to an interference bed sorting machine with a perforated flat iron sheet nozzle structure. Background Technology

[0002] The TBS (Turnover Bed Separator) is a sedimentation separator that uses the turbulent flow generated by the rising water flow at the bottom of the tank to separate coarse particles (0.15–2 mm). The rising water flow with pressure during the TBS separation process is commonly referred to as the top water, which significantly impacts the separation effect. The top water generation process in TBS involves water flowing at a predetermined pressure and velocity into a pressure tank at the bottom of the TBS separator, and then being evenly dispersed into the TBS separation tank through nozzles on the turbulence plate, forming the rising water flow. Therefore, the nozzle structure on the lower turbulence plate of the TBS separator has a significant impact on the formation of the top water. The three-product TBS (Total Product Separator) is a newly developed type of TBS separator, also based on the TBS principle, providing multi-product, high-precision fine-grained mineral separation. TBS and TBS share the same separation principle, and the functions of the turbulence plate, nozzles, and other mechanical structures are identical.

[0003] Currently, the nozzles of both TBS and TPS sorting machines employ a snap-fit ​​structure similar to pins and sleeves, made of polyurethane, primarily to improve nozzle wear resistance. However, industrial applications have revealed two main problems with this nozzle structure:

[0004] 1) In the industrial production of coal preparation plants, circulating water is often used to generate top water. Occasionally, there will be debris such as fallen leaves and rust. If the top water flow path of this nozzle is too long, the debris will easily get stuck in the nozzle, directly affecting the top water pressure. This will prevent the TBS and TPS from forming a stable bed, affecting the separation index and even affecting normal production. The production process must be stopped regularly to inspect the nozzles. The cleaning and maintenance workload is large and the labor intensity of workers is high.

[0005] 2) When the top water pressure is high, the nozzles that are snapped onto the turbulence plate by the snap-fit ​​structure may fall off, resulting in the inability to generate turbulence during the sorting process. This will prevent the formation of disturbance sedimentation in the sorting tank, which will seriously affect the sorting indicators of TBS and TPS.

[0006] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an interference bed sorting machine with a perforated flat iron sheet nozzle structure.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] The purpose of this invention is to provide an interference bed sorting machine with a perforated flat iron sheet nozzle structure, which can solve the problem of nozzles being easily clogged and falling off, affecting normal production.

[0009] To achieve the above objectives, a specific embodiment of this utility model provides an interference bed sorting machine with a perforated flat iron sheet nozzle structure, including a sorting trough, a light material discharge trough, a heavy material discharge trough, and a feed inlet sequentially installed on the sorting trough. A top water interface is fixedly installed on one side of the sorting trough near the bottom. A turbulence plate is fixedly installed inside the sorting trough, and the turbulence plate has several sets of top water openings. Several sets of upper liner plates are detachably fixedly installed on the turbulence plate.

[0010] Multiple sets of flat iron sheets are positioned and welded onto the upper liner plates, and the thickness of the flat iron sheets is 2-8mm.

[0011] The flat iron sheet has a top water hole, which is elliptical in shape.

[0012] In one or more embodiments of this utility model, the length of the flat iron sheet is 10-50 mm and the width is 10-30 mm.

[0013] In one or more embodiments of this utility model, the long side of the top water hole is 3-5 mm and the short side is 1-3 mm.

[0014] In one or more embodiments of this utility model, the multiple sets of upper liner plates are all fan-shaped, and the multiple sets of upper liner plates are all in close contact with the turbulence plate.

[0015] In one or more embodiments of this utility model, a positioning groove is provided on the upper liner, the flat iron sheet is located inside the positioning groove, a central hole is provided on the positioning groove, the top water hole matches the central hole, and the top water hole is connected to the interior of the top water opening through the central hole.

[0016] In one or more embodiments of this utility model, the depth of the positioning groove is equal to the thickness of the flat iron sheet.

[0017] In one or more embodiments of this utility model, the upper liner is provided with a through hole, a bolt is inserted into the through hole, and a screw hole matching the bolt is provided on the turbulence plate. The upper liner is locked and fixed to the turbulence plate by bolts passing through the through hole and the screw hole in sequence.

[0018] In one or more embodiments of this utility model, an enlarged diameter hole is provided on the through hole.

[0019] In one or more embodiments of this utility model, a top water regulating valve is installed on the top water interface.

[0020] In one or more embodiments of this utility model, a central controller is connected to the distal end of the top water regulating valve.

[0021] Compared with the existing technology, this utility model uses a flat iron sheet with a top water hole to be directly welded to the turbulence plate as a nozzle. The connection is firm and reliable and will not fall off. It is low in cost, and the top water has a short running path in the top water hole, so particles or debris are not easy to clog. This greatly reduces the frequency of workers cleaning the nozzle, and reduces the labor intensity and operating costs of workers. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-4 As shown, an interference bed sorting machine with a perforated flat iron sheet nozzle structure according to one embodiment of the present invention includes a sorting tank 1, on which a light material discharge tank 2, a heavy material discharge tank 3, and a feed inlet 4 are sequentially installed. A light material discharge inlet 201 is fixedly installed on the light material discharge tank 2. The light material discharge tank 2 and the heavy material discharge tank 3 are used for discharging the sorted light and heavy materials, respectively. A bell-shaped valve 301 is installed inside the heavy material discharge tank 3 to control the discharge of heavy materials.

[0031] A top water inlet 5 is fixedly installed near the bottom on one side of the sorting tank 1. The top water inlet 5 is used to connect to the top water power source. A top water regulating valve 501 is installed on the top water inlet 5 to regulate the top water pressure. A central controller 6 is connected to the remote end of the top water regulating valve 501, and the use of the top water regulating valve 501 can be controlled through the central controller 6.

[0032] A turbulence plate 7 is fixedly installed inside the sorting tank 1 near the bottom. Several sets of top water openings 701 are opened on the turbulence plate 7.

[0033] Multiple sets of upper liner plates 8 are detachably and fixedly installed on the turbulence plate 7. All sets of upper liner plates 8 are fan-shaped and are in close contact with the turbulence plate 7. The multiple sets of upper liner plates 8 can protect the turbulence plate 7, prevent wear after long-term operation, and effectively enhance the structural strength of the turbulence plate 7, thus extending its service life.

[0034] like Figure 2 As shown, each of the multiple sets of upper liner plates 8 has a positioning groove 801, and a flat iron piece 9 is welded and fixed inside the positioning groove 801. The positioning groove 801 can position the flat iron piece 9 when it is welded and fixed, ensuring the accurate welding position of the flat iron piece 9 and reducing the installation difficulty of the flat iron piece 9.

[0035] like Figure 3 As shown, the flat iron sheet 9 has a top water hole 901, and the positioning groove 801 has a center hole 8011. The top water hole 901 matches the center hole 8011, and the top water hole 901 is connected to the inside of the top water opening 701 through the center hole 8011. In this way, the flat iron sheet 9 can act as a nozzle to evenly push water upward through the top water hole 901.

[0036] Preferably, in this embodiment, the thickness of the flat iron sheet 9 is 5mm, the length is 30mm, and the width is 15mm.

[0037] Specifically, by using a flat iron sheet 9 fixed by welding as a nozzle, the connection is firm and reliable and will not fall off, which effectively solves the problem of existing snap-on nozzles falling off. This ensures that turbulence is generated during the TBS and TPS sorting process, so that disturbance settling can be formed in the sorting tank 1, thus guaranteeing the sorting performance.

[0038] Furthermore, the flat iron sheet 9 is only 5mm thick, resulting in a short water flow path within the orifice, making it less prone to clogging by particles or debris. Simultaneously, the top water hole 901 is elliptical in shape. Preferably, in this embodiment, the long side of the top water hole 901 is 4mm and the short side is 2mm. The varying diameter of the top water hole 901 in different directions further reduces the likelihood of clogging by particles or debris, effectively preventing nozzle clogging. This significantly reduces the frequency of nozzle cleaning by workers, lowering labor intensity and operating costs.

[0039] It is worth noting that the depth of the positioning groove 801 is equal to the thickness of the flat iron sheet 9. In other words, the flat iron sheet 9 can be completely hidden inside the positioning groove 801, making the surface of the upper liner plate 8 relatively flat and easier to clean later.

[0040] like Figure 4 As shown, the upper liner plate 8 has a through hole 802, and a bolt 803 is inserted into the through hole 802. The turbulence plate 7 has a screw hole 702 that matches the bolt 803. The upper liner plate 8 is locked and fixed to the turbulence plate 7 by the bolt 803 passing through the through hole 802 and the screw hole 702 in sequence, thereby realizing the assembly and fixation of the upper liner plate 8 on the turbulence plate 7.

[0041] Specifically, the upper liner plate 8 is assembled and fixed to the turbulence plate 7 using bolts 803, making it easy to replace the upper liner plate 8. When it is necessary to replace the nozzle, the upper liner plate 8 can be directly removed from the turbulence plate 7, allowing all nozzles to be quickly removed, which is convenient for replacing weld-fixed nozzles.

[0042] The through hole 802 has an enlarged diameter hole 8021. After the bolt 803 is screwed into the screw hole 702, the head of the bolt 803 can be hidden inside the enlarged diameter hole 8021 to prevent the bolt 803 from loosening naturally due to external force, thus ensuring the stability of the upper liner plate 8 during installation.

[0043] In use, the flat iron sheet 9 is first welded and fixed inside the positioning groove 801 on the upper liner plate 8, and then the upper liner plate 8 is fixed to the turbulence plate 7 by bolts 803. At this time, the flat iron sheet 9 can be used as a nozzle to push water upward through the top water hole 901, which effectively solves the problem of nozzle falling off and clogging.

[0044] Compared with the prior art, this utility model uses a flat iron sheet 9 with a top water hole 901 directly welded to the turbulence plate 7 as a nozzle. The connection is firm and reliable and will not fall off. It is low in cost. In addition, the top water has a short running path in the top water hole 901, and particles or debris are not easy to clog. This greatly reduces the frequency of cleaning the nozzle by workers, and reduces the labor intensity and operating costs of workers.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
