Description

Technical Field

[0001] The present invention relates to the technical field of solid material color sorters, and particularly to a vertical feeding double-layer ore sorter. Background Art

[0002] Ore color sorters are mainly used for color sorting of relatively hard ore materials such as quartz sand. The color sorting range of color sorters in the prior art is generally large-grained ores with a diameter of 5 - 30 mm. In this way, when fine sand and gravel working conditions are required, after color sorting, the sorted finished products need to be crushed and processed again, which easily leads to the problem that internal impurities in the materials cannot be removed and the quality of the finished products after crushing is limited. On the other hand, the feeding chutes of color sorters in the prior art generally use aluminum profiles, stainless steel materials or other material chutes, and are arranged at a certain angle, so that the sand and gravel fall along the U-shaped bottom surface of the chute. In this way, when the feeding chute discharges materials, the sand and gravel jump greatly, easily resulting in material skipping phenomenon, and when passing through the central viewing point of the color sorter, the sand and gravel are relatively scattered, which is not conducive to visual recognition and thus affects the color sorting accuracy. Moreover, due to the inclined setting of the chute, the friction of the sand and gravel falling is relatively large, which easily causes wear on the chute surface and shortens the service life of the chute. Summary of the Invention

[0003] In order to make up for the deficiencies of the prior art, the present invention provides a vertical feeding double-layer ore sorter to solve the technical problems in the prior art that the internal impurities of the ore sorter with a larger screening particle size cannot be removed, the quality of the finished products after crushing is limited, the sand and gravel jump greatly to cause material skipping phenomenon, and the inclined chute is easily worn.

[0004] To achieve the above object, the following technical solutions are provided:

[0005] A vertical feeding double-layer ore sorter includes a frame, and a feed hopper support, an electric control box, a vibrating hopper, a sorting box A, a sorting box B, a valve box, an overflow hopper, and a feeding chute installed on the frame. A feed hopper is installed on the feed hopper support. The bottom of the sorting box A is connected to an upper layer discharge hopper, and the bottom of the sorting box B is connected to a lower layer discharge hopper. The feed hopper is communicated with the vibrating hopper, the vibrating hopper is communicated with the sorting box A through the feeding chute, and the qualified product notch of the upper layer discharge hopper at the bottom of the sorting box A is communicated with the sorting box B through the feeding chute. The feeding chute is vertically installed on the frame and is composed of a guiding chute and a glass chute.

[0006] Further, the glass chute includes a glass plate A, a glass plate B, side plates A, side plates B, sealing plates A, sealing plates B, and tower spring assemblies;

[0007] The side plates A and B are mirror-symmetrical and each has an open slot and a closed slot; the sealing plate A is fixedly installed above the side of the glass plate A, and the sealing plate B is fixedly installed above the side of the glass plate B;

[0008] The glass plate A is installed in the open notch through the cooperation of the tower spring assembly with the side plate A and the side plate B;

[0009] The glass plate B is fixedly installed in the closed card slot through the cooperation of the side plate A and the side plate B;

[0010] The sealing plate A and the sealing plate B are connected and fixed on the top of the side plate A or the side plate B.

[0011] Further, 2 groups of the tower spring assemblies are respectively and fixedly arranged on the side plate A and the side plate B.

[0012] Further, 6 groups of the blanking chutes are arranged above the sorting box A, and correspondingly 6 groups are arranged above the sorting box B. The number of the lower layer discharge hoppers is the same as that of the blanking chutes arranged above the sorting box B, and the number of the upper layer discharge hoppers is the same as that of the blanking chutes arranged above the sorting box A.

[0013] Further, a buffer plate is arranged in the material guiding groove.

[0014] Further, one discharge hopper air extraction is respectively arranged on the left and right sides of the bottom of the sorting box A and on the left and right sides of the bottom of the sorting box B.

[0015] The advantages and effects of the present invention compared with the prior art are:

[0016] A vertical blanking double-layer ore separator of the present invention uses a blanking chute composed of a material guiding groove and a glass chute to replace the inclined blanking chute in the traditional color sorter. It can mainly be applicable to the color sorting of fine sand and gravel with a particle size of 8-120 meshes in the color sorting of materials, solving the problem that in the prior art, the sand and gravel color sorting can generally only be applicable to large particle size ores, and the internal impurities cannot be removed after the ore color sorting and need to be broken again; multiple groups of the blanking chutes are arranged in parallel, and the blanking path of the sand and gravel can be limited inside the cavity of the blanking chute, solving the problem that the material guiding chute in the prior art has a scattered blanking and easy material jumping, enabling the ore color sorter to more accurately and stably sort the sand and gravel. Furthermore, the vertical blanking double-layer ore separator adopted in the present invention uses a double-layer color sorting method. The qualified products completed in the upper layer sorting can enter the lower layer for further sorting, further improving the final sorting accuracy of the sand and gravel materials; and because the vertical blanking can reduce the friction between the sand and gravel and the side wall of the blanking chute, the service life of the color sorter is significantly improved, thereby helping the user to obtain greater economic value.

Detailed implementation manners

[0025] Such as Figures 1 to 4As shown in the figure, a vertical feeding double-layer ore separator includes a frame 15, a feed hopper support 3, an electric control box 6, a vibrating hopper 2, a sorting box A1, a sorting box B7, a valve box 8, an overflow hopper 9, and a blanking chute 14 installed on the frame 15. A feed hopper 4 is installed on the feed hopper support 3. The bottom of the sorting box A1 is connected to an upper discharge hopper 12, and the bottom of the sorting box B7 is connected to a lower discharge hopper 10. The feed hopper 4 is communicated with the vibrating hopper 2, the vibrating hopper 2 is communicated with the sorting box A1 through the blanking chute 14, and the qualified product notch of the upper discharge hopper 12 at the bottom of the sorting box A1 is communicated with the sorting box B7 through the blanking chute 14; the blanking chute 14 is vertically installed on the frame 15 and consists of a guiding chute 11 and a glass chute 5. The sorting box A1 is located above the sorting box B7 and is mainly an independent cavity for installing electronic components such as CCD and background board lights. The vibrating hopper 2 can continuously and evenly feed the sand and gravel materials into the blanking chute 14 below the vibrating hopper 2; the feed hopper support 3 fixes the feed hopper 4 at a specific position above the vibrating hopper 2; the feed hopper 4 is the material inlet, and during operation, the feeding mechanism throws the materials into the feed hopper 4; the electric control box 6 is an independent cavity for installing electrical components such as power supplies and circuit boards to provide control operations for the ore separator; the valve box 8 is an independent cavity for installing solenoid valves and their electrical drives and gas circuit fittings; the overflow hopper 9 is a hopper body for collecting and guiding the materials falling from the bottom of the glass chute; the upper discharge hopper 12 is a diversion device for separating unqualified products and qualified products after the action of the sorting box A1, and the lower discharge hopper 10 is a diversion device for separating unqualified products and qualified products after the action of the sorting box B7; the blanking chute 14 is vertically arranged. After the sand and gravel materials enter the blanking chute 14, they first enter the guiding chute 11. The guiding chute 11 can provide a buffering and decelerating effect for the sand and gravel materials and guide the sand and gravel materials into the glass chute 5. The glass chute 5 limits the traveling trajectory of the sand and gravel materials within the range of the internal cavity of the glass chute. The materials will also have an accelerating process in the glass chute, limiting the blanking path of the sand and gravel within the cavity of the blanking chute, which can effectively prevent and reduce the problem of material skipping. The blanking of the sand and gravel materials is limited within the specific blanking chute 14, and there will be no problem of U-shaped blanking of the sand and gravel materials in the traditional color sorter, making the blanking more uniform, so that the ore color sorter can sort the sand and gravel more accurately and stably; moreover, due to the vertical blanking, the friction between the sand and gravel and the side wall of the blanking chute 14 can be reduced, significantly improving the service life of the color sorter and the blanking chute of the color sorter.

[0026] As Figures 4 to 5As shown in the figure, the glass chute 5 includes a glass plate A501, a glass plate B502, a side plate A503, a side plate B504, a sealing plate A505, a sealing plate B506, and a tower spring assembly 507; the side plate A503 and the side plate B504 are mirror-symmetrical and each has an open slot and a closed slot; the sealing plate A505 is fixedly installed above the side of the glass plate A501, and the sealing plate B506 is fixedly installed above the side of the glass plate B502; the glass plate A501 is installed in the open slot through the cooperation of the tower spring assembly 507 with the side plate A103 and the side plate B104; the glass plate B502 is fixedly installed in the closed slot through the cooperation of the side plate A103 and the side plate B104; the sealing plate A505 and the sealing plate B506 are connected and fixed to the top of the side plate A503 or the side plate B504, and the fixing method can be welding or threaded connection according to actual needs; the glass plate A501 and the glass plate B502 are the same glass plates, and are distinguished by A and B for better description of the technical solution of the present invention. When the sand and gravel materials pass through the inner cavity of the glass chute 5, the movement trajectory is limited within a specific range by the glass chute 5, and the materials can flow out more evenly from the bottom of the glass chute 5, so that the color sorting work is more accurate. The glass plate A501 is installed in the open slot through the cooperation of the tower spring assembly 507 with the side plate A103 and the side plate B104. Therefore, the distance between the glass plate A501 and the glass plate B502 can be adjusted by adjusting the position of the glass plate A501. The adjustment of the distance can generally be achieved by inserting a support body between the glass plate A501 and the open slot. The operator can use this method to adjust the size of the middle cavity of the glass chute 5 to meet the actual working conditions requirements. The tower spring assembly 507 not only plays a role in fixing the glass plate A501 but also has a shock-absorbing effect.

[0027] As Figures 4 to 5 shown, two groups of tower spring assemblies 507 are respectively and fixedly arranged on the side plate A103 and the side plate B104.

[0028] As Figures 1 to 2 shown, six groups of blanking chutes 14 are arranged above the sorting box A1, and six groups are correspondingly arranged above the sorting box B7. The lower discharge hopper 10 is the same as the blanking chute 14 arranged above the sorting box B7, and the number of upper discharge hoppers 12 is the same as that of the blanking chutes 14 arranged above the sorting box A1. The functions of the lower discharge hopper 10 and the upper discharge hopper 12 are to separate the qualified products and unqualified products of the sand and gravel materials falling from the blanking chute 14 after sorting. Six groups of blanking chutes 14 are arranged above the sorting box A1 and six groups are correspondingly arranged above the sorting box B7, and are arranged side by side. In this way, the falling sand and gravel materials can be divided into six independent spaces for restricted falling, and the falling trajectory of the sand and gravel materials is more controllable, which is beneficial for the sorting box A1 and the sorting box B7 to complete the color sorting work more accurately, and makes the separation of qualified products and unqualified products in the color sorting work more accurate.

[0029] As Figure 6 shown, a buffer plate 111 is provided in the material guiding chute 11. The buffer plate 111 can reduce the falling speed of the sand and gravel materials and make the feeding more uniform, providing conditions for more accurate and stable sorting of the materials when they enter the sorting position after passing through the glass chute 5.

[0030] As Figures 1 to 3 shown, one air extraction outlet 13 is respectively provided on the left and right sides of the bottom of the sorting box A1 and on the left and right sides of the bottom of the sorting box B7. The air extraction outlet 13 of the discharge hopper can extract the dust generated during the feeding of the lower discharge hopper 10 and the upper discharge hopper 12, ensuring a dust-free working environment.

[0031] The vertical feeding double-layer ore separator of the present invention is mainly applicable to the color sorting of fine sand and gravel with a mesh size of 8 - 120. During operation, the sand and gravel are added to the feed hopper 4 by an external feeding device. The materials pass through the feed hopper 4 to the vibrating hopper 2, and the vibrating hopper 2 continuously and evenly feeds the sand and gravel into the feeding chute 14 below the vibrating hopper 2. After being buffered by the material guiding chute 11 at the upper part of the feeding chute 14, the materials enter the glass chute 5, and there is an acceleration process during the travel in the glass chute 5. Subsequently, they are divided into the sorting area of the sorting box A1 for sorting. The unqualified products flow out from the unqualified product notch of the upper discharge hopper 12, and the qualified products flow into the feeding chute 14 below the sorting box A1 from the qualified product notch of the upper discharge hopper 12, and then enter the sorting area of the sorting box B7 for secondary sorting work to further improve the accuracy of the qualified products. After the sorting in the sorting box B7 is completed, the qualified products flow out from the qualified product notch of the lower discharge hopper 10, and the unqualified products flow out from the unqualified product notch of the lower discharge hopper 10, completing the sorting work. During the whole process, the dust generated during the sorting process is collected by the air extraction outlet 13 of the discharge hopper, and the sorting process is dust-free and environmentally friendly.

[0032] The present invention is not limited to the above embodiments. The embodiments are only exemplary and are intended to explain the present invention, rather than being construed as a limitation to the present invention.
