[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.

[0038] As Figure 1 shown, the present application provides a non-metallic ore impurity removal device, including a cleaning pool 1, a crusher 2, a slurry mixing pool 3, an iron removal device 4, a pickling tank 5, and a water washing tank 6 connected in series in sequence;

[0039] A lifting device 11 is arranged in the cleaning pool 1 for transferring the washed ore out of the cleaning pool 1;

[0040] An ultrasonic vibrator head 12 is also arranged in the cleaning pool 1;

[0041] The pickling tank 5 is also connected to the acid solution storage tank 7;

[0042] The water washing tank 6 is also connected to the fresh water storage tank 8.

[0043] During use, inject fresh water into the cleaning tank 1 (the specific injection volume depends on the actual situation), pour the non-metallic ore to be decontaminated (quartz ore is taken as an example in this application) into the cleaning tank 1. At the same time, turn on the ultrasonic vibrator 12 in the cleaning tank 1, and use the ultrasonic waves emitted by the ultrasonic vibrator 12 to remove the soil, sand, etc. attached to the surface of the ore. When the ore after cleaning falls near the lifting device 11, it is transferred into the crusher 2 through the lifting device 11 for crushing. The crusher 2 in this application is a jaw crusher or a pair-roll crusher. The crusher 2 crushes the large ore into smaller ore particles (such as 1 - 2 mm), and then transfers the ore particles into the pulp adjusting tank 3 to be adjusted into a pulp with an appropriate concentration (such as a concentration of 40 - 50%), and then transfers the adjusted pulp into the iron removal device 4 to use the iron removal device 4 to attract and remove the magnetic substances in the pulp. Then filter and dehydrate the pulp after iron removal (a filter press can be set between the iron removal device 4 and the pickling tank 5 to filter and dehydrate the pulp). Since the magnetic separation of the iron removal device 4 can only remove substances with strong magnetism, and substances with weak magnetism (mainly iron ores associated with non-metallic ores, such as iron oxides containing magnetism) are difficult to be removed by magnetic separation, so the pulp after magnetic separation by the iron removal device 4 is dehydrated and then transferred into the pickling tank 5, and the acid solution is used to dissolve and remove the magnetic substances and metal compounds in the ore.

[0044] Transfer the dehydrated ore particles into the pickling tank 5, add a certain amount of acid solution (such as dilute hydrochloric acid with a concentration of 5 - 10%), and the amount of the acid solution should be able to submerge the ore particles. Through pickling, the metal compounds (from the associated metal ores of the non-metallic ore) in the ore particles react with the acid solution, and these metal compounds are removed. After pickling, dehydrate the ore particles and then transfer them into the water washing tank 6.

[0045] For the ore particles transferred into the water washing tank 6, use the fresh water in the fresh water storage tank 8 to wash away the residual acid solution on the surface of the ore particles. The washed ore particles are then discharged into the corresponding collection device for storage for subsequent processing.

[0046] The present application provides a non-metallic ore impurity removal device. By setting up a cleaning tank 1, impurities such as soil adhered to the surface of the non-metallic ore are removed by ultrasonic waves. Then, the cleaned ore is crushed by a crusher 2 and made into pulp in a pulp mixing tank 3. Next, the pulp is input into an iron removal device 4 to magnetically separate strong magnetic impurities in the ore. Furthermore, the magnetically separated ore is transferred to a pickling tank 5 for pickling to remove metal compounds mixed in the ore. Finally, the residual acid solution on the surface of the pickled ore is washed away by water washing. Through the combined use of the above-mentioned equipment, the non-metallic ore is purified, providing an effective way to purify non-metallic ore, which has the characteristics of easy operation and better impurity removal effect.

[0047] As Figure 1 shown, optionally, a partition plate 13 is also inclinedly arranged in the cleaning tank 1, and the input end of the lifting device 11 is arranged on the upper surface of the partition plate 13;

[0048] A plurality of through holes are formed in the partition plate 13.

[0049] During use, since the partition plate 13 is inclined (inclined towards the input end of the lifting device 11), these ores will slide towards the lifting device 11. At the same time, the ultrasonic vibration head 12 in the cleaning tank 1 is turned on, and the ultrasonic waves emitted by the ultrasonic vibration head 12 are used to remove the soil, sand, etc. attached to the surface of the ore. Since a plurality of through holes are formed in the partition plate 13, the soil, sand, etc. removed by ultrasonic waves will leak through the through holes and fall to the bottom of the tank. Moreover, during the sliding process of the ore towards the lifting device 11, the soil, etc. on the partition plate 13 will also be pushed to the through holes and fall.

[0050] As Figure 2 shown, optionally, the lifting device 11 includes a lifting cylinder 111 and a lifting auger 112 arranged in the lifting cylinder 111;

[0051] The lifting cylinder 111 is inclinedly arranged, and one end extends into the cleaning tank 1. The lifting cylinder 111 is supported by a frame 113;

[0052] A plurality of through holes are formed in the spiral belt of the lifting auger 112.

[0053] Optionally, when the ore after cleaning falls close to the lifting device 11, the lifting auger 112 on the lifting device 11 starts to lift the cleaned ore. Since through holes are formed in the spiral belt of the auger, during the process of the ore being lifted by the lifting auger 112, the moisture in the ore will fall into the cleaning tank 1 through the through holes in the spiral belt.

[0054] As Figure 2 and Figure 3As shown, optionally, a first spray head 114 is provided at the upper edge of the output end of the lifting cylinder 111, and the first spray head 114 sprays towards the inside of the lifting cylinder 111;

[0055] The first spray head 114 is connected to the sedimentation tank 116 through a circulation pump 115; the sedimentation tank 116 is connected to the cleaning tank 1.

[0056] The cleaning water of the ore after cleaning in the cleaning tank 1 contains a large amount of sediment and the like and appears turbid. A part of this cleaning water is led out to the sedimentation tank 116 to settle the impurities therein, and the supernatant liquid after sedimentation is transferred into the first spray head 114 through the circulation pump 115 for cleaning the ore lifted by the lifting device 11.

[0057] As Figure 4 shown, optionally, the pickling tank 5 includes a tank body 51 and an inner tank 52 provided in the tank body 51;

[0058] A stirring paddle 53 is provided in the inner tank 52, and the stirring paddle 53 is connected to a motor 54 provided above the inner tank 52;

[0059] The motor 54 is supported by a bracket 55 fixed to the tank body 51;

[0060] The inner tank 52 is integrally of a hollow structure.

[0061] In this application, the bracket 55 and the tank body 51 are detachably connected, such as by snap connection or other connection methods, and the inner tank 52 can be fixed to the tank body 51 through structures such as snap fasteners.

[0062] Since the magnetic separation of the iron removal device 4 can only remove substances with strong magnetism, and substances with weak magnetism (mainly iron oxides) are difficult to be removed by magnetic separation, the ore pulp after magnetic separation by the iron removal device 4 is dehydrated and then transferred into the pickling tank 5, and the magnetic substances and metal compounds in the ore are dissolved and removed by using acid solution.

[0063] The dehydrated ore particles are transferred into the inner tank 52 of the pickling tank 5. A certain amount of acid solution (such as dilute hydrochloric acid with a concentration of 5-10%) is contained in the tank body 51. The amount of the acid solution should be able to submerge the ore particles in the inner tank 52. Then the motor 54 is started, and the motor 54 drives the stirring paddle 53 to rotate to stir the ore particles, so that the metal compounds in the ore particles react with the acid solution to remove these metal compounds. After pickling, the inner tank 52 is lifted out of the acid solution level in the pickling tank 5, drained of water, and then the ore particles drained of water are transferred into the water washing tank 6.

[0064] As Figure 5 shown, optionally, the water washing tank 6 is also connected to an acid solution storage tank 7.

[0065] In this application, the water washing tank 6 is also connected to the acid liquid storage tank 7, and the acid-containing washing liquid obtained by washing the ore particles after pickling can be transferred into the acid liquid storage tank 7 for preparing acid liquid.

[0066] As Figure 6 shown, optionally, the water washing tank 6 includes a tank body 61;

[0067] The interior of the tank body 61 is divided into an upper washing area and a lower liquid storage area by a horizontally arranged filter plate 60;

[0068] A plurality of second spray heads 62 are arranged along the circumferential direction on the inner side surface of the upper part of the tank body 61, and the second spray heads 62 are connected to the clean water storage tank 8 through a liquid transfer pump 63;

[0069] A discharge port 601 is formed on the side surface of the tank body 61, and a liquid discharge port 602 is formed at the bottom;

[0070] The liquid discharge port 602 is connected to the acid liquid storage tank 7.

[0071] The ore particles transferred into the water washing tank 6 are placed on the filter plate 60. At the same time, the liquid transfer pump 63 is started to transfer the clean water in the clean water storage tank 8 into the second spray heads 62 arranged in the upper part of the tank body 61 and spray the clean water onto the ore particles to wash away the residual acid liquid on the surface of the ore particles. The acid-containing washing liquid washed from the ore particles falls into the lower liquid storage area through the filter holes on the filter plate 60. The acid-containing washing liquid in the liquid storage area can be collected and transferred into the acid liquid storage tank 7 through the liquid discharge port 602 for preparing acid liquid. The washed ore particles are then discharged through the discharge port 601 to a corresponding collection device for storage, so as to facilitate subsequent processing.

[0072] A non-metallic ore impurity removal device is used as follows:

[0073] During use, clean water is injected into the cleaning tank 1 (the specific amount of water injection depends on the actual situation), and the non-metallic ore to be decontaminated (taking quartz ore as an example in this application) is poured into the cleaning tank 1. Since the partition plate 13 is inclined (tilted towards the input end of the lifting device 11), these ores will slide towards the lifting device 11. At the same time, the ultrasonic vibrator 12 in the cleaning tank 1 is turned on, and the ultrasonic waves emitted by the ultrasonic vibrator 12 are used to remove the soil, sand, etc. attached to the surface of the ore. Since a plurality of through holes are provided on the partition plate 13, the soil, sand, etc. removed by the ultrasonic waves will leak through the through holes and fall to the bottom of the tank. Moreover, during the process of the ore sliding towards the lifting device 11, the soil and the like falling on the partition plate 13 will also be pushed to the through holes and fall. The cleaning water of the ore after cleaning in the cleaning tank 1, which contains a large amount of sediment and the like, will become turbid. A part of this cleaning water is led out to the sedimentation tank 116 to sediment the impurities therein, and the supernatant after sedimentation is transferred into the first spray head 114 through the circulation pump 115 for cleaning the ore lifted by the lifting device 11. In this way, the cleaning water in the cleaning tank 1 is recycled, which can make full use of water resources and has the characteristic of saving water.

[0074] When the ore after cleaning falls near the lifting device 11, the lifting auger 112 on the lifting device 11 starts to lift the cleaned ore through the lifting auger 112. Since through holes are provided on the spiral belt of the auger, during the process of the ore being lifted by the lifting auger 112, the water in the ore will fall into the cleaning tank 1 through the through holes on the spiral belt. When the ore is lifted by the lifting auger 112 to the outlet, the first spray head 114 provided at the upper edge of the output end of the lifting cylinder 111 sprays the supernatant in the sedimentation tank 116 to wash the surface of the ore and remove the muddy water and the like adhered to the surface of the ore. The cleaned ore is transferred into the crusher 2 through the lifting device 11 for crushing. The crusher 2 in this application is a jaw crusher or a pair-roll crusher. The crusher 2 crushes the large ore into smaller ore particles (such as 1 - 2 mm), and then the ore particles are transferred into the pulp preparation tank 3 to be prepared into a pulp with an appropriate concentration (such as a concentration of 40 - 50%). Then the prepared pulp is transferred into the iron removal device 4 to use the iron removal device 4 to attract and remove the magnetic substances in the pulp. Then the pulp after iron removal is filtered and dehydrated (a filter press can be set between the iron removal device 4 and the pickling tank 5 to filter and dehydrate the pulp). Since the iron removal device 4 can only remove substances with strong magnetism by magnetic separation, and the weakly magnetic substances (mainly iron oxides) are difficult to be removed by magnetic separation, the pulp after magnetic separation by the iron removal device 4 is dehydrated and then transferred into the pickling tank 5, and the acid solution is used to dissolve and remove the magnetic substances and metal compounds in the ore.

[0075] Transfer the dehydrated ore particles into the inner tank 52 of the pickling tank 5. There is a certain amount of acid solution (such as dilute hydrochloric acid with a concentration of 5-10%) in the tank body 51. The amount of the acid solution should be able to submerge the ore particles in the inner tank 52. Then start the motor 54 and drive the stirring paddle 53 to rotate by the motor 54 to stir the ore particles, so that the metal compounds in the ore particles react with the acid solution to remove these metal compounds. After pickling, lift the inner tank 52 out of the acid solution level in the pickling tank 5, drain the water, and then transfer the ore particles with drained water into the water washing tank 6.

[0076] The ore particles transferred into the water washing tank 6 are placed on the filter plate 60. At the same time, start the transfer pump 63 to transfer the clear water in the clear water storage tank 8 into the second spray head 62 arranged at the upper part of the tank body 61 and spray it on the ore particles to wash away the residual acid solution on the surface of the ore particles. The acid-containing washing liquid washed from the ore particles falls into the lower liquid storage area through the filter holes on the filter plate 60. The acid-containing washing liquid in the liquid storage area can be collected and transferred into the acid solution storage tank 7 through the drain port 602 for preparing the acid solution. The washed ore particles are then discharged through the discharge port 601 to a corresponding collection device for storage for subsequent processing.
