Description

Technical Field

[0001] The invention belongs to the technical field of mineral processing equipment, and in particular relates to a pulping and separation device and a discharging system. Background Art

[0002] In the process of mineral processing and production, the ore crushing and grinding process equipment requires high investment and high energy consumption. The energy consumption of crushing and grinding can account for 40%-70% of the total energy consumption of mineral processing, and some can even reach 80%. The grinding cost accounts for a large proportion of this. Therefore, the industry has been advocating "more crushing and less grinding" in order to reduce production costs. The products of the multiple crushing operation need to be pre-pulped and graded before entering the mill. This can ensure that the qualified particle size produced by the multiple crushing operation enters the separation operation directly without grinding, thereby improving the capacity of the crushing and grinding system and increasing the production capacity of the concentrator. At present, when the material is pulped and sent to the screen surface of the screening machine for grading, due to the influence of the feeding position, uneven feeding often occurs on the screen surface, thereby affecting the grading efficiency of the screening machine. In the prior art, in order to solve the problem of uneven feeding on the screen surface, a pulp separator is usually used. Such as Figure 1 and Figure 2 As shown, after pulping, the pulp is pumped or flows by gravity to the pulp separation barrel of the pulp separator for pulping. The pulp separation barrel is a circular pulp separation barrel with multiple pipes connected to the bottom of the barrel. The pulp flows by gravity to the screen surface of the screen through the pipes. In order to achieve the gravity flow of the slurry, a large height difference is required between the top and the bottom of the pulp separator. Since the amount of slurry in each pipe is not controlled, the pulp separation barrel cannot solve the problem of uneven feeding on the screen surface. In addition, since the pulp separator is provided with blades for pulping, when the slurry contains large particles, the blades will wear faster. Summary of the invention

[0003] In view of the current technical problems, the present invention aims to provide a pulping and separation device and a discharging system, wherein the pulping and separation device can solve the technical problem in the prior art of how to improve the uniformity of material distribution on the screen surface of the screening machine.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A pulping and separating device, the structural features of which are: comprising a trough body, a water spray pipe arranged on the trough body and a plurality of opening adjustment mechanisms, the water outlet on the water spray pipe is located in the trough body; a mounting port and a plurality of discharge ports located below the mounting port are arranged on the side wall of the trough body, the plurality of discharge ports are arranged at intervals in the horizontal direction of the side wall of the trough body, and the discharge port is located above the bottom of the trough body; an opening adjustment mechanism is arranged above each discharge port, the opening adjustment mechanism is connected to the top wall of the mounting port by an elastic element, and the slurry in the trough body flows out through the connection between the discharge port and the opening adjustment mechanism; the opening adjustment mechanism can move up and down in the mounting port as the amount of slurry flowing through the opening adjustment mechanism changes; when the amount of slurry flowing through the opening adjustment mechanism increases, the opening adjustment mechanism moves downward to reduce the size of the discharge port; when the amount of slurry flowing through the opening adjustment mechanism decreases, the opening adjustment mechanism moves upward to increase the size of the discharge port.

[0006] The elastic element can be a spring. When the pulping and separation device of the present invention is used, after the material falls into the trough body, water is sprayed through the water outlet of the water spray pipe to make pulp. Since the discharge port is arranged above the bottom of the trough body, and there is a distance between the discharge port and the bottom of the trough body, part of the slurry is stored in the trough body. After the material falls, it is suspended at the bottom of the trough body, thereby increasing the probability of mixing with water flushing. After the material is slurried, it turns over and flows out of the trough body. When the hopper feeding position is not located at the center of the trough body, the slurry surface in the trough body is an inclined surface. The pulping and separation device of the present invention is suitable for pulping materials containing large particles, and the device has no height requirements. The slurry in the trough body overflows from the discharge port and flows onto the opening adjustment mechanism, and flows out through the opening adjustment mechanism. The opening adjustment mechanism moves up and down in the installation port due to the impact of the slurry. The moving direction and distance of the opening adjustment mechanism are related to the elastic element and the impact force of the slurry. The slurry flow rate at different slurry depths is Where ψ is the velocity coefficient, g is the gravitational acceleration, and h is the slurry depth. The amount of slurry flowing through the opening adjustment mechanism is The impact force of the slurry on the opening adjustment mechanism is Among them, ρ is the density of ore pulp, and A is the area of ​​the flow surface. The impact force of ore pulp on the opening adjustment mechanism is mainly affected by the gravity of the ore pulp flowing out of the opening adjustment mechanism, so the impact force on the opening adjustment mechanism is only related to the size of the flow surface and the depth of the flow surface. When a large amount of ore pulp impacts the opening adjustment mechanism, the impact force on the opening adjustment mechanism is greater than the tension of the elastic element at this time, and the opening adjustment mechanism moves downward, gradually reducing the size of the discharge port, thereby reducing the ore pulp flow at the opening adjustment mechanism; when the ore pulp flow decreases, the impact force on the opening adjustment mechanism is weakened, and the impact force is less than the tension of the elastic element, and the opening adjustment mechanism moves upward, gradually increasing the size of the discharge port, thereby increasing the ore pulp flow at the opening adjustment mechanism; when the impact force on the opening adjustment mechanism is equal to the tension of the elastic element, the opening adjustment mechanism is stable, and the ore pulp flow is stable. When the ore pulp liquid surface in the tank body is a plane, the sizes of the discharge ports on the tank body are consistent, and the amount of ore pulp flowing out of the discharge ports is consistent. When the slurry surface in the tank is an inclined surface, the discharge port at the high liquid level is smaller than the discharge port at the low liquid level, thereby reducing the difference in the amount of slurry flowing out of each discharge port on the tank body and improving the uniformity of the slurry outflow rate at each discharge port of the tank body.

[0007] Preferably, the opening adjustment mechanism includes an inverted U-shaped plate and a guide groove, the side walls of the inverted U-shaped plate are respectively arranged on both sides of the bottom wall of the installation port, the top of the inverted U-shaped plate is connected to the top wall of the installation port by an elastic element, and the side wall of the inverted U-shaped plate arranged on the inner side of the tank body is arranged adjacent to the inner side wall of the tank body; one end of the guide groove along the length direction is an open structure, and the other end side wall is provided with a guide port, and the side wall of the guide groove provided with the guide port is connected to the side wall of the inverted U-shaped plate arranged on the outer side of the tank body; during the upward and downward movement of the opening adjustment mechanism, the guide port is connected to the discharge port or the discharge port is closed by the side wall of the inverted U-shaped plate arranged on the inner side of the tank body. The slurry in the tank body flows into the guide groove through the discharge port and the guide port, and flows out through the guide groove. When the amount of slurry flowing through the guide groove is large, the tension on the elastic element is greater than the elastic force of the elastic element at this time, so that the guide groove drives the inverted U-shaped plate to move downward, the elastic element is extended, and at the same time the discharge port is reduced or even closed. When the amount of slurry flowing through the guide trough decreases, the tension on the elastic element is less than the elastic force of the elastic element at this time. Under the action of the elastic force, the inverted U-shaped plate drives the guide trough to move upward, the elastic element shortens, and the discharge port is enlarged. The size of each discharge port on the side wall of the trough body is changed by moving the inverted U-shaped plate up and down, so that the slurry flow at each discharge port is stable and the difference is reduced.

[0008] Specifically, the top wall of the guide port is at the same height as the bottom of the inverted U-shaped plate side wall arranged on the inner side of the tank body, the width of the discharge port is not less than the width of the guide port, and the height of the discharge port is not greater than the height of the guide port.

[0009] Preferably, a plurality of mounting posts are provided on the top wall of the mounting opening along the length direction, and the plurality of mounting posts are respectively arranged in one-to-one correspondence with the plurality of discharge ports; one end of the elastic element is connected to the mounting post, and the other end is connected to the inverted U-shaped plate; the height of the mounting post in the mounting opening is adjustable, and the height difference between two adjacent mounting posts is b1 and b2 are the opening and closing widths of the discharge ports corresponding to two adjacent mounting columns when the slurry volume in the tank is stable, and h1 and h2 are the liquid level depths at the discharge ports corresponding to two adjacent mounting columns when the slurry volume in the tank is stable. The tension of the elastic element is F 拉 =kx, k is the elastic coefficient, x is the telescopic distance. The impact force of the slurry is balanced with the tension of the elastic element, so F = F 拉 ,and Right now Among them, the flow area A = a*b, a is the width of the diversion port, and b is the opening and closing width of the discharge port when the slurry flow in the tank is stable. Assume constant but Opening and closing width of the discharge port In order to keep the amount of slurry passing through each discharge port consistent, kx is a constant value, indicating that the opening and closing width b of the discharge port is inversely proportional to the liquid level depth. That is, under the condition of keeping the amount of slurry passing through the discharge port consistent, the deeper the liquid level, the smaller the opening and closing width of the discharge port needs to be. Since kx is a constant value, the elongation of the elastic element is consistent. In order to ensure that the opening and closing widths of the discharge ports are inconsistent, the elastic element can only be installed in steps to form different opening and closing widths. The installation height difference between two adjacent elastic elements is calculated as follows: The adjacent elastic element In order to ensure that the slurry outflow at the corresponding outlets under two adjacent elastic elements is consistent, kx1=kx2, but The installation height difference between two adjacent elastic elements is Δh. b1 is determined according to the design flow rate, and h1 and h2 are determined according to the slurry flow rate and the valve body arrangement spacing. Since the upper end of each elastic element is connected to the mounting column, the mounting height difference is set for each mounting column, so that each elastic element is installed in a stepped manner, so that the outflow slurry volume at each outlet is close, so that the outlet material can enter the subsequent screening operation linearly and evenly.

[0010] Preferably, guide rails are provided on both sides of the discharge port, and the guide rails are arranged on the outer side walls of the trough body, and the guide rails are arranged along the height direction of the trough body; guide blocks are provided on both sides of the outer side walls of the guide trough, and the guide blocks are arranged along the height direction of the guide trough; when the opening adjustment mechanism moves up and down, the guide blocks move up and down along the guide rails. By providing the guide rails and the guide blocks, the moving direction of the guide trough is guided.

[0011] Specifically, the guide rail includes a connecting block and a guiding block, the connecting block is connected to the outer side wall of the groove body; the guiding block is arranged on the side wall of the connecting block, and the guiding block is arranged toward the guiding block, and the side wall of the guiding block abuts against the outer side wall of the guiding block. By arranging the guiding block and the guiding block, the side wall of the guiding block abuts against the outer side wall of the guiding block, thereby limiting the displacement of the guide groove to the side of the groove body, and limiting the horizontal direction of the guide groove.

[0012] Preferably, the water spray pipe is arranged along the length direction of the trough body close to the side wall of one side of the trough body, and the discharge port is arranged on the side wall of the trough body opposite to the water spray pipe; the side wall of the water spray pipe is provided with multiple water outlets along the length direction, and the water outlets are arranged toward the center line of the bottom wall of the trough body along the length direction.

DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0033] like Figure 3As shown, a pulping and pulping device of this embodiment includes a tank body 1, fourteen opening adjustment mechanisms 4, and a water spray pipe 2 arranged in the tank body 1, and a plurality of water outlets 7 are arranged on the side wall of the water spray pipe 2 along the length direction. The water spray pipe 2 is arranged along the length direction of the tank body 1 close to the side wall of one side of the tank body 1, and the plurality of water outlets 7 are arranged toward the center line of the bottom wall of the tank body 1 along the length direction. Figure 4 As shown, the side wall of the tank body 1 is provided with a mounting port 8 and fourteen discharge ports 6 located below the mounting port 8, and the fourteen discharge ports 6 are arranged at intervals in the horizontal direction along the side wall of the tank body 1. The discharge port 6 is arranged on the side wall of the tank body 1 opposite to the water spray pipe 2, and the distance between the bottom wall of the discharge port 6 and the bottom of the tank body 1 is equal to three times the maximum particle size of the material in the tank body 1. Fourteen mounting columns 15 are arranged along the length direction on the top wall of the mounting port 8, and the fourteen mounting columns 15 are arranged one by one corresponding to the fourteen discharge ports 6. The mounting columns 15 are connected to the top wall of the mounting port 8 by threads, so that the height of the mounting columns 15 in the mounting port 8 can be adjusted.

[0034] like Figure 5 , Figure 6 and Figure 7 As shown, the opening adjustment mechanism 4 includes an inverted U-shaped plate 401 and a guide groove 402. The side walls of the inverted U-shaped plate 401 are respectively arranged on both sides of the bottom wall of the installation opening 8. The top of the inverted U-shaped plate 401 is connected to the installation column 15 through an elastic element 3. The elastic element 3 is a spring. The side wall of the inverted U-shaped plate 401 arranged on the inner side of the tank body 1 is arranged adjacent to the inner side wall of the tank body 1. One end of the guide groove 402 along the length direction is an open structure, and a guide port 403 is arranged on the side wall of the other end. The side wall of the guide groove 402 with the guide port 403 is connected to the side wall of the inverted U-shaped plate 401 arranged on the outer side of the tank body 1. The width of the guide port 403 is not less than the width of the discharge port 6. As the amount of slurry flowing through the guide trough 402 changes, the opening adjustment mechanism 4 can move up and down in the installation port 8, so that the guide port 403 is connected to the discharge port 6 or the discharge port 6 is closed by the side wall of the inverted U-shaped plate 401 arranged on the inner side of the tank body 1. The top wall of the guide port 403 and the bottom of the side wall of the inverted U-shaped plate 401 arranged on the inner side of the tank body 1 are located at the same height, the width of the discharge port 6 is equal to the width of the guide port 403, and the height of the discharge port 6 is equal to the height of the guide port 403. Guide rails 5 are provided on both sides of the discharge port 6, and the guide rails 5 are arranged on the outer side wall of the tank body 1, and the guide rails 5 are arranged along the height direction of the tank body 1. The guide rails 5 include a connecting block 501 and a guide block 502, the connecting block 501 is connected to the outer side wall of the tank body 1, and the guide block 502 is arranged on the side wall of the connecting block 501. Guide blocks 9 are provided on both sides of the outer side walls of the guide trough 402, and the guide blocks 9 are arranged along the height direction of the guide trough 402. The guide block 502 is disposed toward the guide block 9, and the side wall of the guide block 9 abuts against the outer side wall of the guide block 502. When the opening adjustment mechanism 4 moves up and down, the guide block 9 moves up and down along the side wall of the guide block 502.

[0035] like Figure 8 As shown, a pulping and separation device of this embodiment includes a feed hopper 10, a screen 11 and the pulping and separation device as described above, the tank body 1 is arranged below the feed hopper 10, and the bottom outlet of the feed hopper 10 is connected to the inner cavity of the tank body 1, and the discharge port 6 is arranged above the screen surface of the screen 11. Fig.11 As shown, the bottom outlet of the feed hopper 10 is arranged close to the side wall of the tank body 1 along the width direction. Figure 8 As shown, the inverted U-shaped plate 401 is located at the top of the discharge port 6, the discharge port 6 is connected to the guide port 403, and the discharge port 6 is in a fully open state. At this time, the slurry outflow at the discharge port 6 is the largest. Fig. 9 As shown, the inverted U-shaped plate 401 moves downward, the discharge port 6 is connected to the guide port 403, but the opening and closing width of the discharge port 6 is reduced. At this time, the slurry outflow at the discharge port 6 is reduced. Fig.10 As shown, the inverted U-shaped plate 401 continues to move downward, and the discharge port 6 is closed by the inverted U-shaped plate 401. At this time, the slurry outflow at the discharge port 6 is zero.

[0036] The slurry in the tank body 1 overflows from the discharge port 6 and flows into the guide groove 402 of the opening adjustment mechanism 4, and then flows out through the guide groove 402. The opening adjustment mechanism 4 moves up and down in the installation port 8 due to the impact of the slurry. The moving direction and distance of the opening adjustment mechanism 4 are related to the tension of the elastic element 3 and the impact force of the slurry. In order to make the flow rate of the slurry outflowing from each discharge port 6 close, the installation height of the elastic element 3 is designed. The slurry flow rate at different slurry depths is Where, ψ is the velocity coefficient, g is the gravity acceleration, and h is the slurry depth. The amount of slurry flowing through the opening adjustment mechanism 4 is The impact force of the slurry on the opening adjustment mechanism 4 is Where ρ is the density of the slurry, and A is the area of ​​the flow surface. The impact force of the slurry on the opening adjustment mechanism 4 is mainly affected by the gravity of the slurry flowing out of the opening adjustment mechanism 4. Therefore, the impact force on the opening adjustment mechanism 4 is only related to the size of the flow surface A and the depth h of the flow surface. The tension of the elastic element 3 is F 拉 =kx, k is the elastic coefficient, x is the telescopic distance. When the amount of slurry in the tank 1 is stable, the impact force of the slurry is balanced with the tension of the elastic element 3, so F = F 拉 ,and Right now Among them, the flow area A = a*b, a is the width of the guide port 403, and b is the opening and closing width of the discharge port 6 when the amount of slurry in the tank body 1 is stable. Therefore, Assume constant but Opening and closing width of discharge port 6 In order to keep the amount of slurry passing through each discharge port 6 consistent, kx is a constant value, indicating that the opening and closing width b of the discharge port 6 is inversely proportional to the liquid level depth. That is, under the condition of keeping the amount of slurry passing through each discharge port 6 consistent, the deeper the liquid level, the smaller the opening and closing width of the discharge port 6 needs to be. Since kx is a constant value, the elongation of the elastic element 3 is consistent. In order to ensure that the opening and closing width of the discharge port 6 is inconsistent, such as Fig.11 As shown, different opening and closing widths can only be formed by installing the elastic element 3 in steps. The height difference between two adjacent elastic elements 3 is calculated as follows: The adjacent elastic element 3 In order to ensure that the slurry outflow at the corresponding outlet 6 below two adjacent elastic elements 3 is consistent, kx1=kx2, but The installation height difference between two adjacent elastic elements 3 is Δh. b1 is determined according to the design flow rate, h1 and h2 are determined according to the slurry flow rate and the valve body arrangement spacing, so that the installation height difference between the fourteen elastic elements 3 can be calculated. Figure 4 As shown, since the tops of the elastic elements 3 in the installation openings 8 are all connected to the installation columns 15, the heights of the fourteen installation columns 15 can be set according to the installation height differences between the elastic elements 3, so that the fourteen elastic elements 3 are installed in a stepped manner.

[0037] After the powder falls into the tank body 1 through the feed hopper 10, it is sprayed with water through the water outlet 7 of the water spray pipe 2 to form a slurry. Since the discharge port 6 is arranged above the bottom of the tank body 1, there is a distance between the discharge port 6 and the bottom of the tank body 1, so that part of the slurry is stored in the tank body 1, and the powder is suspended at the bottom of the tank body 1 after falling, thereby increasing the probability of being washed and mixed with water, and the powder is slurried and discharged from the tank body 1. Fig.11 As shown, a stable slurry liquid surface 14 with a high left side and a low right side is formed in the tank body 1. The slurry overflows from the discharge port 6 and the guide port 403 and flows onto the guide slot 402, and flows out through the guide slot 402. The guide slot 402 is impacted by the slurry and drives the inverted U-shaped plate 401 to move up and down in the installation port 8. The moving direction and distance of the guide slot 402 are related to the impact force of the elastic element 3 and the slurry. Figure 8 As shown, the discharge port 6 is connected to the guide port 403, and the discharge port 6 is in a fully open state. A large amount of slurry impacts the guide groove 402, and the impact force on the guide groove 402 is greater than the pulling force of the elastic element 3. The elastic element 3 expands the expansion distance x, and the guide groove 402 moves downward. Fig. 9As shown, the opening and closing width b of the discharge port 6 becomes smaller, reducing the slurry flow rate, causing the elastic element 3 to expand and contract. When the slurry flow rate in the guide groove 402 decreases, the impact force on the guide groove 402 is weakened and is less than the tension of the elastic element 3, and the elastic element 3 expands the distance x. The guide groove 402 moves upward, increasing the opening and closing width b of the discharge port 6, increasing the slurry flow rate in the guide groove 402, and causing the elastic element 3 to expand the distance x. When the impact force of the slurry flow rate is balanced with the tension of the elastic element 3, the expansion distance of the elastic element 3 is constant, the valve 6 is stable, and the slurry flow rate is stable. At this time, as shown in FIG. Fig.11 As shown, the opening and closing width b of the discharge port 6 on the side wall of the trough body 1 gradually increases from left to right, so that the slurry flow at each discharge port 6 is stable and close, and finally the amount of slurry falling onto the screen surface of the screen machine 11 tends to be uniform and is not affected by the setting position of the feed hopper 10.
