Description

Technical Field

[0001] This invention relates to the field of belt filter presses, specifically a belt filter press for treating wastewater from zirconium-titanium ore production. Background Technology

[0002] Belt filter press is a very practical and efficient sludge dewatering equipment. It separates the solid and liquid in the sludge through mechanical extrusion dewatering. After the liquid is squeezed out, the solid impurities are squeezed into a cake shape, which makes it convenient to collect and treat the solid impurities.

[0003] In the production of zirconium-titanium ore, wet beneficiation is required. After beneficiation, concentrate dewatering is necessary. This involves separating the concentrate and water mixture using a belt filter press. By squeezing out the water from the concentrate, lumpy or cake-shaped concentrate is obtained, making it easier for workers to collect. The filter belt has a woven structure and a certain degree of elastic deformation, allowing it to tightly wrap the solid mud like a "bandage," thereby expelling water under pressure.

[0004] When the concentrate solid-liquid mixture is placed above the filter belt, a distribution structure is used to ensure that the solid-liquid mixture is evenly distributed on the filter belt in order for the two mutually pressing filter belts to fully squeeze out the water in the mixture. As the filter belts move, they can squeeze the evenly distributed solid-liquid mixture. However, in the actual implementation of the existing distribution structure, multiple sets of pry blocks arranged in parallel and staggered rows are used to divert the solid-liquid mixture multiple times. This method cannot achieve an effective uniform distribution effect and does not take into account the possibility of solids clumping in the solid-liquid mixture. When the solid components in the solid-liquid mixture do not enter the two filter belts for squeezing and dewatering, areas with more solid components tend to accumulate, creating a bulge between the two filter belts. Since the two filter belts are elastically pressed together by two pressure rollers, when one of the areas between them bulges, it becomes impossible to effectively squeeze and dewater the areas with less solid components, thus reducing the dewatering effect of the solid-liquid mixture.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-10The diagram shows a belt filter press for treating wastewater from zirconium-titanium ore production. It includes: a frame 1; a set of first pressure rollers 2 and a set of second pressure rollers 3 rotatably mounted inside the frame 1; the first pressure rollers 2 are distributed above the second pressure rollers 3; each set contains several first pressure rollers 2 and several second pressure rollers 3; a first filter belt 4 is driven and sleeved on the outer surface of the several first pressure rollers 2; the lower part of the first filter belt 4 is S-shaped, and the upper part of the first filter belt 4 is horizontal; a second filter belt 5 is also driven and sleeved between the several second pressure rollers 3 and the first pressure rollers 2; the upper part of the second filter belt 5 is also S-shaped. The first filter belt 4 and the second filter belt 5 are S-shaped and overlap each other. The equipment frame 1 is provided with a first tensioning component and a second tensioning component, which are used to make the first filter belt 4 and the second filter belt 5 overlap tightly. The outer wall of the equipment frame 1 is fixedly mounted with a first motor 9. The ends of two of the first pressure rollers 2 and the second pressure roller 3 that are close to each other are fixedly fitted with a first synchronous gear 8, and the two first synchronous gears 8 mesh with each other. The end of the first pressure roller 2 or the second pressure roller 3 equipped with the first synchronous gear 8 is fixed to the output end of the first motor 9.

[0033] It also includes a solid-liquid mixing application unit located above the first filter belt 4, used to uniformly apply the solid-liquid mixture to the upper surface of the first filter belt 4. The solid-liquid mixing application unit includes an application frame 11 mounted on the top of the equipment frame 1, and the lower port of the application frame 11 is inclined. The upper port of the application frame 11 is fixedly equipped with a discharge pipe through a limiting sleeve 12. The zirconium titanium ore mixture that needs to be separated into solid and liquid is transported to the interior of the limiting sleeve 12 and the application frame 11 through the discharge pipe. The interior of the limiting sleeve 12 is equipped with two synchronously counter-rotating rollers 13. The lower port of the application frame 11 is also provided with a diversion component.

[0034] Each roller 13 is fixedly fitted with a second synchronous wheel 15 at its end, and the two second synchronous wheels 15 mesh with each other. The outer wall of the limiting sleeve 12 is also fixedly mounted with a second motor 14, and the output end of the second motor 14 is fixed to the end of one of the rollers 13. The outer surface of each roller 13 is also provided with grooves that are circumferentially distributed. Through the grooves, the roller 13 can break and separate the agglomerated mineral particles. When the second motor 14 is running, under the action of the two meshing second synchronous wheels 15, the two rollers 13 can rotate synchronously in opposite directions, and the direction of rotation of the two is to transport the zirconium titanium ore solid-liquid mixture towards the application frame 11.

[0035] The diversion component includes several diversion blocks 16 that are equidistantly distributed in a straight line inside the lower port of the application frame 11. The diversion blocks 16 are triangular in shape, with the pointed corners of the diversion blocks 16 facing the inside of the application frame 11. A limiting rod 18 is placed on the outside of the application frame 11, and a connecting rod 17 is fixedly provided between the limiting rod 18 and each diversion block 16. The limiting rod 18 is slidably mounted on the top of the equipment frame 1 through a limiting seat, and the sliding direction of the limiting rod 18 is parallel to the axis of the first pressure roller 2 or the second pressure roller 3. A pushing component is also provided between the limiting rod 18 and the equipment frame 1. The first motor 9 can drive the pushing component to run, so that the limiting rod 18 carries several diversion blocks 16 to move back and forth in a small range inside the application frame 11, so that the solid-liquid mixture can be more evenly distributed on the upper surface of the first filter belt 4.

[0036] The pushing component includes a rotating shaft 21 rotatably mounted on the outer wall of the equipment frame 1. The rotating shaft 21 is connected to the output end of the first motor 9 via a synchronous gear and a synchronous toothed belt. A turntable 22 is fixedly sleeved on the outer surface of the rotating shaft 21. Several circumferentially equidistant inclined arc push blocks 23 are fixedly arranged at one end of the turntable 22 near the equipment frame 11. One end of the limiting rod 18 slides in contact with the inclined surface of the inclined arc push block 23. The outer surface of the limiting rod 18 is also fixedly sleeved. A limiting ring 19 is provided, and a tension spring 20 is fixedly provided between the limiting ring 19 and one of the limiting seats. The tension spring 20 is sleeved on the outside of the limiting rod 18. Through the cooperation of the tension spring 20 and the limiting ring 19, an elastic tension can be applied to the limiting rod 18. When the turntable 22 rotates and pushes the limiting rod 18 frequently through the inclined arc push block 23, the limiting rod 18 can carry several diverting blocks 16 to perform a small range of reciprocating sliding movement inside the lower port of the distribution frame 11.

[0037] The first tensioning component includes a rocker plate 6 located inside the second filter belt 5, and the rocker plate 6 is rotatably mounted inside the equipment frame 1. A baffle fixed inside the equipment frame 1 is placed below the rocker plate 6, and a first spring 7 is fixedly installed between the baffle and the rocker plate 6. The rocker plate 6 is inclined, and the rocker edge of the rocker plate 6 abuts against the outside of one of the first pressure rollers 2. Through the elastic pushing of the rocker plate 6 by the first spring 7, the first filter belt 4 and the second filter belt 5 can be elastically squeezed against the outer wall of the first pressure roller 2. When the solid-liquid mixture passes between the two, the water will be squeezed out.

[0038] An arc-shaped baffle 10 is also provided above the rocker plate 6. The arc-shaped baffle 10 is located at the intersection of the first filter belt 4 and the second filter belt 5. The arc-shaped baffle 10 is fixed to the inside of the equipment frame 1. Under the transmission of the first filter belt 4, the solid-liquid mixture will be conveyed towards the arc-shaped baffle 10. The arc-shaped baffle 10 can guide the solid-liquid mixture to the intersection of the first filter belt 4 and the second filter belt 5, thereby performing extrusion dehydration treatment on the solid-liquid mixture.

[0039] There are two second tensioning components, which are respectively assembled on the outside of the first filter belt 4 and the second filter belt 5. The second tensioning component includes a connecting arm 36 rotatably sleeved on the end of the first pressure roller 2 or the second pressure roller 3, and a lever is rotatably sleeved on the other end of the connecting arm 36. The outer wall of the equipment frame 1 has an arc groove for sliding of the lever. The lever slides in contact with the first pressure roller 2 or the second pressure roller 3. A push block 37 is slidably assembled inside the connecting arm 36. The outer surface of the first pressure roller 2 or the second pressure roller 3 has a plurality of circumferentially equidistant... The distributed ratchet grooves 41, the push block 37 near the end of the ratchet groove 41 is fixedly provided with a ratchet block 39 by the push rod 38, and the ratchet block 39 is movably engaged with the ratchet groove 41. The end of the push block 37 away from the push rod 38 is fixedly provided with a fourth spring 40 between it and the connecting arm 36. Under the elastic pressure of the fourth spring 40, the ratchet groove 41 can restrict the rotation direction of the ratchet block 39, so that when the connecting arm 36 is rotated by the lever to wind up the first filter belt 4 or the second filter belt 5 to make it tight, there will be no back rotation.

[0040] Example 2: Please refer to Figures 6-8 This embodiment is a further explanation of other embodiments. A sludge scraping unit is also provided on the side of the first filter belt 4 and the second filter belt 5 away from the arc-shaped baffle 10. The sludge scraping unit includes two sets of transverse grooves 24 formed inside the equipment frame 1, and the two sets of transverse grooves 24 are respectively distributed on the outer sides of the first filter belt 4 and the second filter belt 5. A slider 25 is slidably fitted inside each set of transverse grooves 24, and a sliding rod 32 is fixedly provided on the outside of the slider 25. A sleeve block 31 fixed to the equipment frame 1 is slidably fitted on the outer surface of the sliding rod 32. A third spring 33 is also fitted on the outside of 32, and the two ends of the third spring 33 are fixed to the sleeve block 31 and the slider 25 respectively. A straight rod 26 is inserted between the two sliders 25 in the same group. Under the elastic pressure of the third spring 33, the two straight rods 26 can be squeezed against the outer walls of the first filter belt 4 and the second filter belt 5 respectively, so that the straight rods 26 scrape off the mud adhering to the surface of the first filter belt 4 and the second filter belt 5, and let the mud fall into the collection box, thereby completing the dehydration, separation and collection treatment of zirconium titanium ore.

[0041] A sliding component is also provided between the first synchronous gear 8 and the straight rod 26. The sliding component includes a limiting plate 27 fixed at both ends of the straight rod 26, and a second spring 28 is fixedly provided between the limiting plate 27 and the slider 25. At least two limiting posts 29 that limit the limiting plate 27 are also fixedly provided on the outer wall of the slider 25. The limiting posts 29 and the limiting plate 27 are slidably fitted. A ball block 30 is fixedly provided on the outer wall of one of the limiting plates 27 near the first synchronous gear 8. Several paddles 34 that actuate the ball block 30 are also provided on the outer surface of the first synchronous gear 8. When the first synchronous gear 8 rotates with the paddles 34, it can continuously press the limiting plate 27 through the ball block 30, thereby allowing the straight rod 26 to slide back and forth between the two sliders 25.

[0042] Example 3: Please refer to Figure 7 and Figure 8 This embodiment is a further explanation of other embodiments. The depth to which the slider 25 is embedded in the transverse groove 24 is a, and the depth of the transverse groove 24 is b, where a < b. The number of straight rods 26 inserted between each group of sliders 25 is at least one. The outer surface of the straight rod 26 is also fixedly fitted with several retaining rings 35 that are distributed in a straight line at equal intervals. When the straight rod 26 slides back and forth with several retaining rings 35, the retaining rings 35 can frequently move the outer walls of the woven first filter belt 4 and the second filter belt 5, further improving the separation effect of zirconium titanium ore solid particles from the two.

[0043] Working principle: During the process of conveying the solid-liquid mixture of zirconium titanate into the limiting sleeve 12, the two rollers 13 move synchronously in opposite directions inside the limiting sleeve 12 by the second motor 14, which can disperse the agglomerated solid particles, so that the solid-liquid mixture entering the application frame 11 is free of agglomerated substances. Through the action of several diversion blocks 16 at the lower end of the application frame 11, the solid-liquid mixture can be diverted, so that the solid-liquid mixture is evenly distributed on the upper end surface of the first filter belt 4. Moreover, the first motor 9 drives the first filter belt 4 and the second filter belt 5 to run synchronously in opposite directions, and can also rotate the turntable 22. Through the continuous pushing of the inclined arc push block 23 against the end of the limiting rod 18, plus the action of the tension spring 20, the several diversion blocks 16 can move back and forth continuously at the lower end of the application frame 11, which can further improve the uniformity of the solid-liquid mixture distributed on the upper end surface of the first filter belt 4.

[0044] refer to Figure 3 The solid-liquid mixture moves towards the arc-shaped baffle 10 under the conveying of the first filter belt 4. Finally, guided by the arc-shaped baffle 10, the solid-liquid mixture moves between the first filter belt 4 and the second filter belt 5. As the first filter belt 4 and the second filter belt 5 are conveyed, they encapsulate and squeeze the solid-liquid mixture. The squeezed water drips directly onto the wet area at the bottom of the inner side of the equipment frame 1. After the water is squeezed out, the solid components between the first filter belt 4 and the second filter belt 5 will become mud cakes or mud lumps. Under continuous conveying, the solid components are scraped off by the straight bar 26, and the mud cakes or mud lumps fall to the dry area for centralized collection and processing.

[0045] Because the first filter belt 4 and the second filter belt 5 are woven, the woven lines on their surfaces are obvious. When the two are squeezed against the zirconium-titanium ore solid-liquid mixture, the solid particles are easily squeezed into the woven gaps of the first filter belt 4 and the second filter belt 5. When the first synchronous gear 8 rotates, it can continuously press the ball block 30 through the paddle 34, causing the straight rod 26 to move back and forth frequently with the retaining ring 35. Through several retaining rings 35, the outer surfaces of the first filter belt 4 and the second filter belt 5 are continuously scraped and the woven lines are continuously paddled, so that the solid particles remaining in the woven gaps can also fall into the dry area for collection and treatment, thus improving the collection effect of zirconium-titanium ore solid materials.
