Description

Technical Field

[0001] This utility model relates to the field of acid leaching residue treatment, and more specifically, to a novel filtration device for mineral acid leaching residue. Background Technology

[0002] In the mineral processing industry, acid leaching is a common extraction process used to extract valuable metals or other compounds from ores. During this process, the mineral raw material is leached with acid, producing a leachate containing the target compound and insoluble acid leaching residue. The treatment of this residue is a crucial step in the mineral processing flow, as it not only relates to the effective utilization of resources but also directly impacts environmental protection and governance. Current methods for filtering mineral acid leaching residue still have the following shortcomings:

[0003] When filtering traditional mineral acid leaching residue, the residual minerals in the acid leaching residue containing acid are usually filtered and separated together. During the filtration process, the residual mineral residue can cause significant damage or blockage to the filter screen, making it inconvenient for long-term filtration and separation and subsequent cleaning.

[0004] Therefore, we have made improvements to this and proposed a new type of filtration device for mineral acid leaching residue. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all, of the embodiments of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] like Figure 1-5 As shown, this embodiment proposes a novel filtration device for mineral acid leaching residue, including a tank 1, with a filtration and separation mechanism 2 provided on one side of the tank 1.

[0032] like Figure 2As shown, the filtration and separation mechanism 2 includes a guide frame 201, a chute 202, a separation inclined plate 203, a drain hole 204, a baffle plate 205, a guide hopper 206, a motor 207, a rotating column 208, a placement plate 209, a filter cylinder 210, and a drain pipe 211. The guide frame 201 is bolted to the top of the tank 1. Both chute 202 are formed on the inner wall of the guide frame 201. The separation inclined plate 203 is slidably connected to the inner wall of the chute 202. The drain hole 204 penetrates the interior of the separation inclined plate 203. The baffle plate 205... 05 is fixedly connected to one side of the separation inclined plate 203, the baffle plate 205 is located at the top of the leakage hole 204, the guide bucket 206 is fixedly connected to the bottom of the guide frame 201, the motor 207 is bolted to the bottom of the tank body 1, the rotating column 208 is coaxially set at the output end of the motor 207, the placement plate 209 is fixedly connected to the top of the rotating column 208, the filter cylinder 210 is threadedly connected to the top of the placement plate 209, and the drain pipe 211 is fixedly connected to the bottom of the tank body 1 and is connected to the interior of the tank body 1. The acid leaching residue containing acid is slowly poured onto the separating inclined plate 203 and allowed to flow naturally. The baffle plate 205 intercepts residual minerals and some of the acid leaching residue. When the acid leaching residue containing acid exceeds the height of the baffle plate 205, it will fall into the filter cylinder 210 through the drain hole 204 and the guide bucket 206. The motor 207 is started, causing the rotating column 208, the placement plate 209, and the filter cylinder 210 to rotate at high speed, which throws the acid in the filter cylinder 210 out of the filter cylinder 210 and through the drainage... Liquid pipe 211 discharges from tank 1, while acid leaching residue in the acid solution is intercepted in filter cylinder 210. During subsequent cleaning, the separation inclined plate 203 can be pulled out of guide frame 201 through slide 202 to clean the mineral residue and some acid leaching residue on the separation inclined plate 203. When cleaning filter cylinder 210, the fixation between guide frame 201 and tank 1 can be released first, and then the fixation between filter cylinder 210 and placement plate 209 can be released. After the filter cylinder 210 is removed from tank 1, it can be cleaned carefully.

[0033] like Figure 3 As shown, an intercepting ring 3 is fixedly connected to the inner bottom wall of the tank 1. An annular groove 4 is formed on the top of the intercepting ring 3, and a stabilizing ring 5 is fixedly connected to the bottom of the placement plate 209. The bottom of the stabilizing ring 5 is located inside the annular groove 4. When the placement plate 209 rotates at a certain height, the stabilizing ring 5 will rotate synchronously in the annular groove 4 of the intercepting ring 3, improving the stability of the placement plate 209 during rotation. Furthermore, the intercepting ring 3 and the stabilizing ring 5 work together to prevent the acid in the tank 1 from damaging the rotating column 208.

[0034] like Figure 4As shown, a feed pipe 6 is fixedly connected to one side of the guide frame 201, and a solenoid valve 7 is installed on one side of the feed pipe 6. The feed pipe 6 is connected to the interior of the guide frame 201, and the solenoid valve 7 is electrically connected to an external power supply. By using the feed pipe 6 and the solenoid valve 7 together, the manual operation of pouring the acid leaching residue can be reduced. At the same time, the solenoid valve 7 can also control the rate at which the acid leaching residue is poured in, thus preventing accidents.

[0035] like Figure 4 As shown, a storage tank 8 is provided at the top of the separating inclined plate 203, and multiple drainage holes 9 are provided through the interior of the baffle plate 205. The storage tank 8 can increase the interception capacity of the separating inclined plate 203 for acid leaching residue and residual minerals; and the continuous injection of new acid leaching residue can continuously squeeze the acid leaching residue on the separating inclined plate 203, so that the acid remaining in the acid leaching residue is discharged into the filter cylinder 210 through the drainage holes 9.

[0036] like Figure 2 As shown, two extension rods 10 are fixedly connected to the top of the separation ramp 203, and a pull handle 11 is fixedly connected to the top of the extension rods 10. When cleaning the separation ramp 203 later, the separation ramp 203 can be quickly pulled out using the extension rods 10 and the pull handle 11 for easy cleaning.

[0037] like Figure 4 As shown, a shielding cover 12 is slidably connected to the top of the guide frame 201, and a tempered glass 13 is installed inside the shielding cover 12. The shielding cover 12 can cover the top of the guide frame 201 to prevent acid from splashing and causing injury to external personnel when it flows, while the tempered glass 13 allows external personnel to easily observe the flow of acid leaching residue on the separation inclined plate 203.

[0038] like Figure 5 As shown, a stabilizing groove 14 is provided at the bottom of the guide bucket 206, and the top of the filter cylinder 210 is located inside the stabilizing groove 14. When the filter cylinder 210 rotates at high speed, the stabilizing groove 14 can limit the top of the filter cylinder 210 to prevent it from shaking or deviating when rotating at high speed.

[0039] Specifically, in use, the novel filtration device for mineral acid leaching residue involves injecting the acid-containing residue into the guide frame 201 through the feed pipe 6, and controlling the rate of injection via the solenoid valve 7. The acid-containing residue solution flows naturally on the separation inclined plate 203. Due to the large volume and weight of the residual minerals, they continuously sink and become stuck in the storage tank 8 as they flow with the acid leaching residue. When the acid-containing residue exceeds the height of the baffle plate 205, it falls into the filter cylinder 210 through the drain hole 204 and the guide bucket 206. The continuous injection of new acid leaching residue continuously compresses the residue on the separation inclined plate 203, causing the acid remaining in the residue to be squeezed out. The liquid is discharged into the filter cylinder 210 through the drain hole 9; the motor 207 is started, causing the rotating column 208, the placement plate 209 and the filter cylinder 210 to rotate at high speed, which throws the acid liquid in the filter cylinder 210 out of the filter cylinder 210 and discharges it out of the tank 1 through the drain pipe 211, while the acid leaching residue in the acid liquid will be intercepted in the filter cylinder 210; during subsequent cleaning, the separation inclined plate 203 can be quickly pulled out for cleaning by using the extension rod 10 and the pull handle 11; when cleaning the filter cylinder 210, the fixation between the guide frame 201 and the tank 1 can be released first, and then the fixation between the filter cylinder 210 and the placement plate 209 can be released, and the filter cylinder 210 can be removed from the tank 1 for detailed cleaning.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
