Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing equipment, in particular to a sawtooth wave jig. Background Art

[0002] In the process of recycling and comprehensive utilization of valuable metals in ferroalloy waste slag, after the water-quenched slag is crushed, it is usually necessary to use a jig to re-select the tailings to recover the valuable metals in the tailings. The sawtooth wave jig has a small footprint and is simple and convenient to operate. It is a new high-efficiency, energy-saving, and environmentally friendly mineral processing equipment developed and produced in recent years. It has a good effect on the beneficiation of various metals and is especially suitable for the beneficiation of fine-grained minerals. It plays an extremely important role in the recycling and treatment of metal smelting slag. However, the most common sieve plates on the sawtooth wave jig on the market are all welded one-piece structures. During use, the sieve holes will be damaged by the impact of sand and gravel, which will cause sand and gravel to leak easily and affect the sorting efficiency. Sometimes, just because of a small damage point, the entire sieve plate needs to be replaced. The replacement is inconvenient, time-consuming and labor-intensive, and the replacement cost is also relatively high. Utility Model Content

[0003] The main purpose of the utility model is to overcome the defects of the above-mentioned background technology and provide a sawtooth wave jig.

[0004] To achieve the above-mentioned purpose, the sawtooth wave jigger proposed in the utility model comprises a frame, a mineral processing trough arranged on the frame, a cone bucket connected to the mineral processing trough through a rubber diaphragm, a cam mechanism connected to the cone bucket and a screen plate arranged in the mineral processing trough, the screen plate is formed by splicing a plurality of groups of screen mesh components, the screen mesh component comprises a supporting screen frame, a screen mesh and a pressing screen frame, a fixed steel ring is convexly provided on the inner wall of the mineral processing trough, the supporting screen frame is detachably connected to the fixed steel ring, the screen mesh is pressed and mounted on the supporting screen frame through the pressing screen frame, a positioning groove is provided on the side of the supporting screen frame, and a positioning convex strip is provided on the other side of the supporting screen frame opposite to the positioning groove, and when two adjacent groups of the screen mesh components are spliced, the positioning convex strip is stuck in the positioning groove. The sieve plate is made up of multiple groups of screen components. When the screen on one group of screen components is found to be worn and damaged, the corresponding screen component can be taken out and replaced separately without replacing the entire sieve plate. The operation is easy, time-saving and labor-saving, and effectively saves costs. When splicing the sieve plates, two adjacent groups of screen components are clamped together by positioning convex strips and positioning grooves, which can improve the overall stability and reliability of the sieve plate.

[0005] To further optimize the technical solution, the mesh holes on the screen are long strip mesh holes, and the aperture of the long strip mesh holes is 90mm×5mm. By setting the mesh holes to a 90mm×5mm long strip mesh hole structure, the pressure distribution in the horizontal direction can be more uniform, the speed difference is smaller, the energy loss is lower, the water flow speed fluctuation is smaller, the flow process is more stable, and a stable upward water flow effect can be formed, which helps to improve the sorting efficiency.

[0006] To further optimize the technical solution, the periphery of the upper and lower screens of the long strip screen holes are both chamfered. By chamfering the periphery of the long strip screen holes, a larger flow space is provided, the chance of material clogging in the screen holes is reduced, and the friction and collision of the material in the screen holes can be reduced, reducing the wear of the screen, thereby extending its service life.

[0007] To further optimize the technical solution, the peripheral widths of the fixed steel ring, the screen-bearing frame and the screen-pressing frame are all less than 40 mm. By minimizing the side width, the impact on the rising water flow is reduced to increase the looseness of the bed layer and further improve the sorting efficiency.

[0008] To further optimize the technical solution, a feed hopper is provided on one side of the ore dressing tank, a tailings outlet is provided on the other side of the ore dressing tank, and a guide plate is provided below the bottom outlet of the feed hopper, and the guide plate is arranged obliquely. By providing the guide plate to guide the material into the ore dressing tank, the material is prevented from falling vertically and directly impacting the screen below, thereby extending the service life of the screen.

[0009] To further optimize the technical solution, the guide plate includes a downslope section, an arc transition section and an upslope section. The upper surfaces of the downslope section, the arc transition section and the upslope section are connected and together constitute the entire guide surface. The guide surface of the arc transition section is a concave arc surface, and the guide surface of the upslope section extends obliquely upward from right to left. The lower surface of the arc transition section abuts against the screen plate. The material flows downward along the downslope section to the arc transition section and then changes direction. Under the action of inertia, it is slightly thrown upward along the upslope section onto the screen plate, avoiding the material from directly scouring and hitting the screen plate, causing wear of the screen, and further extending the service life of the screen.

[0010] To further optimize the technical solution, slide rails are provided on both sides of the top opening of the ore dressing tank, and covers are provided on the slide rails, and both ends of the cover plates are slidably connected to the slide rails on both sides. The cover plates are provided to prevent water in the ore dressing tank from splashing out and affecting the on-site working environment and equipment.

[0011] To further optimize the technical solution, the two ends of the cover plate are respectively provided with inner flanges, and when the cover plate is placed on the top of the ore dressing tank, the inner flanges are clamped at the bottom end of the slide rail. By providing the inner flanges for clamping, the cover plate and the ore dressing tank are prevented from being easily separated.

[0012] To further optimize the technical solution, a handle is provided on the cover plate, so that the staff can carry the cover plate more conveniently.

[0013] To further optimize the technical solution, the cover plate is made of transparent plastic material. At the same time, the cover plate is made of transparent plastic material, which is convenient for the staff to observe the working conditions inside the ore dressing tank.

[0014] The beneficial effects of the utility model include: by splicing multiple groups of screen components into a screen plate, during the jigging and re-selection process, if it is found that the screen on one group of the screen components is worn and damaged, the corresponding screen component can be taken out, and the new screen component can be installed and fixed to the fixed steel ring to complete the replacement without replacing the entire screen plate, which is simple to operate and saves time and effort. The taken out screen component can be reused by re-clamping it between the screen pressing frame and the screen supporting frame after the screen is replaced, which effectively saves the use cost; and by providing positioning grooves and positioning convex strips on the sides of the screen supporting frame, when two adjacent groups of screen components are spliced ​​together, the positioning convex strips and the positioning grooves are mutually engaged, which can effectively improve the overall stability and reliability of the screen plate.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0025] See also Figures 1 to 5In one embodiment, a sawtooth wave jigger is disclosed, comprising a frame 1, a ore dressing trough 2 arranged on the frame 1, a cone bucket 4 connected to the ore dressing trough 2 through a rubber diaphragm 3, a cam mechanism 5 connected to the cone bucket 4 and a screen plate 6 arranged in the ore dressing trough 2. Specifically, the ore dressing trough 2 is arranged on the top of the frame 1, the bottom of the ore dressing trough 2 is connected to the cone bucket 4 through the rubber diaphragm 3, and the cone bucket 4 is provided with a concentrate discharge port 401. The output end of the cam mechanism 5 is connected to the cone bucket 4, and is used to drive the cone bucket 4 to intermittently move up and down vertically so that the water flow in the ore dressing trough 2 produces a sawtooth wave-shaped fluctuation curve; the screen plate 6 is spliced ​​by a plurality of groups of screen mesh components 601, and the screen mesh components 601 include a screen frame 6011, a screen mesh 6012 and a screen pressing frame 6013. A fixed steel ring 201 is convexly provided on the inner wall of the middle part of the ore dressing trough 2, and the screen frame 60 11 is detachably connected to the fixed steel ring 201. Specifically, the screen frame 6011 is fixed to the fixed steel ring 201 by tightening the fixing bolts, and the screen 6012 is fixedly installed on the screen frame 6011 by pressing the screen frame 6013. Specifically, the screen 6012 is placed on the screen frame 6011 and then the pressing screen frame 6013 is pressed on, and then the fixing screws are used to lock it, so that the pressing screen frame 6013 and the screen frame 6011 clamp the screen 6012 around, a positioning groove 6014 is provided on the side of the screen frame 6011, and a positioning convex strip 6015 is provided on the other side of the screen frame 6011 opposite to the positioning groove 6014. When two adjacent groups of screen assemblies 601 are spliced ​​together, the positioning convex strip 6015 is inserted into the positioning groove 6014 to improve the overall stability and reliability of the screen plate 6. In this embodiment, multiple groups of screen assemblies 601 are spliced ​​into a screen plate 6. During the jigging and re-selection process, if the screen 6012 on one group of screen assemblies 601 is found to be worn and damaged, the corresponding screen assembly 601 is taken out and a new screen assembly 601 is installed and fixed to the fixed steel ring 201 without replacing the entire screen plate 6. The operation is simple, time-saving and labor-saving. Moreover, the taken out screen assembly 601 can be clamped between the screen pressing frame 6013 and the screen supporting frame 6011 after replacing the screen 6012, and can be reused next time, effectively saving the use cost.

[0026] In some embodiments, the mesh holes on the screen 6012 are set to a strip mesh hole 6016 structure, and the aperture of the strip mesh hole 6016 is 90 mm×5 mm. During the jig sorting process, the water medium flows up and down through the mesh holes to form a water flow. During the flow of the water through the mesh holes, eddy currents are easily generated and part of the energy is consumed, affecting the smooth flow of the water flow, and further affecting the washing effect of the jig. By setting the mesh holes to a strip mesh hole 6016 structure of 90 mm×5 mm, the pressure distribution in the horizontal direction is more uniform, the speed difference is smaller, the energy loss is lower, the water flow speed fluctuation is smaller, the flow process is more stable, and a stable upward water flow effect can be formed, which helps to improve the sorting efficiency.

[0027] In some embodiments, the peripheries of the upper and lower screens of the long strip screen holes 6016 are chamfered. By chamfering the periphery of the long strip screen holes 6016, a larger circulation space is provided, the chance of material clogging in the screen holes is reduced, and the friction and collision of the material in the screen holes can be reduced, reducing the wear of the screen 6012, thereby extending its service life.

[0028] In some embodiments, the peripheral widths of the fixed steel ring 201, the screen frame 6011 and the screen pressing frame 6013 are all less than 40 mm. Since the rising water flow cannot pass through the steel plate (the edges of the fixed steel ring 201, the screen frame 6011 and the screen pressing frame 6013), the water flow direction will automatically change direction, bypass the steel plate and mix with other rising water flows to form a water flow mixing zone. The rising impulse of the water flow in the mixing zone will weaken the impact on the sorting efficiency. By reducing the edge widths of the fixed steel ring 201, the screen frame 6011 and the screen pressing frame 6013, the looseness of the bed layer on the screen 6012 can be increased, thereby improving the sorting efficiency.

[0029] In a preferred embodiment, a feed hopper 202 is provided on one side of the ore dressing tank 2, a tailings outlet 203 is provided on the other side of the ore dressing tank 2, and a guide plate 204 is provided below the bottom outlet of the feed hopper 202, and the guide plate 204 is inclined. After the material to be sorted comes out of the feed hopper 202, it is introduced into the ore dressing tank 2 through the guide plate 204, so as to prevent the screen 6012 below from being impacted for a long time and being easily worn.

[0030] In a specific example, the guide plate 204 includes a downslope section 2041, an arc transition section 2042 and an upslope section 2043. The upper surfaces of the downslope section 2041, the arc transition section 2042 and the upslope section 2043 are connected and together constitute the entire guide surface. The guide surface of the arc transition section 2042 is a concave arc surface, and the guide surface of the upslope section 2043 extends obliquely upward from right to left. The lower surface of the arc transition section 2042 abuts against the screen plate 6. The material to be sorted flows downward along the downslope section 2041 under the action of gravity, changes direction after passing through the arc transition section 2042, and is slightly thrown upward along the upslope section 2043 under the action of inertia onto the screen plate 6, avoiding direct scouring of the screen plate 6, causing wear of the screen 6012, and extending the service life of the screen 6012.

[0031] In a preferred embodiment, slide rails 205 are provided at both sides of the top opening of the ore dressing tank 2, and covers 206 are provided on the slide rails 205. Both ends of the covers 206 are slidably connected to the slide rails 205 at both sides. The covers are provided to prevent water from splashing out of the ore dressing tank 2 during production and dripping onto the electrical part of the cam mechanism 5 below, causing equipment damage, and to maintain the on-site working environment.

[0032] In a specific example, inner flanges 2061 are respectively provided at both ends of the cover plate 206. When the cover plate 206 is placed on the top of the mineral processing tank 2, the inner flanges 2061 are clamped on the bottom end of the slide rail 205. The inner flanges 2061 hook the bottom surface of the slide rail 205 to prevent the cover plate 206 from being separated from the mineral processing tank 2 in the up-down or front-back directions.

[0033] In a specific example, a handle 2062 is provided on the cover plate 206. The handle 2062 is provided to facilitate the staff to hold the cover plate for installation.

[0034] In a specific example, the cover plate 206 is made of a transparent plastic material, and the transparent plastic material is preferably an acrylic transparent plastic plate. When the cover plate 206 is covered, it is still convenient to check the working conditions in the mineral processing tank 2.
