Description

Technical Field

[0001] The invention relates to the technical field of ore dressing and transportation, and in particular to a chute device. Background Art

[0002] A chute is a trough on the ground that transports materials from high to low. The transported materials can slide down automatically in the chute. It is a common equipment in mineral processing plants. In the mineral processing industry, gravity chutes are often used to transport slurry. Due to the needs of process layout, the slurry transportation path often needs to turn. The flowing slurry has a large impact force. At the same time, the abrasiveness of the slurry makes the turning part of the chute easily damaged by abrasion under the impact of the slurry for a long time, thereby reducing the use efficiency of the chute and causing unnecessary shutdowns and maintenance for the overall process production. Through process calculations, in order to ensure the fluidity of the slurry, gravity chutes have corresponding gravity slopes. When the chute conveying distance is long and the drop between the chute feeding point and the discharge point is large, the flow rate of the slurry will become faster and faster. The potential energy of the slurry flowing into the discharge point is very large. The increase in flow rate will increase the abrasiveness of the slurry, especially the impact on the turning part of the chute and the downstream discharge point, which will have an adverse effect on the safety of the chute and is not conducive to downstream equipment. In addition, the larger slurry flow rate causes a larger lateral load on the chute, and the lateral impact of the slurry on the turning point of the chute also increases the lateral load of the chute, which places higher strength requirements on the brackets or hangers used to support the chute.

DETAILED DESCRIPTION

[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that the described embodiments may be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of the claims. In addition, in this specification, the drawings are not drawn to scale and the same reference numerals represent the same parts.

[0025] Figure 1 is a schematic front view of the chute device of the present invention, Figure 2 : is a left side schematic diagram of the chute device of the present invention, such as Figure 1 and Figure 2 As shown, the chute device of the present invention includes a linear chute 1 and a turning chute 2, wherein the linear chute 1 is provided with a buffer trough 5, and the conveying medium (for example, medium such as slurry) is accumulated in the buffer trough 5 to form a first buffer zone, and the turning chute 2 is connected to the linear chute 1, and the turning chute 2 is provided with a buffer box 7, and the conveying medium is accumulated in the buffer box 7 to form a second buffer zone, and the subsequent conveying medium impacts the first buffer zone and then flows into the turning chute 2, impacting the second buffer zone, and the transmission direction of the conveying medium is changed through the turning chute 2.

[0026] The present invention reduces the kinetic potential energy of the conveying medium by forming a first buffer zone in the buffer trough 5 and a second buffer zone in the buffer box 7, and changes the transmission direction of the conveying medium by turning the chute 2, thereby achieving the effect of bending the pipe and preventing the bent pipe from being easily damaged by scouring for a long time.

[0027] The chute device of the present invention can reasonably dissipate energy of the conveying medium in the chute device, reduce the wear of the conveying medium on the chute, enhance the wear resistance of easily worn parts, reduce the self-generated lateral load in the chute device, and improve the safety and use efficiency of the chute device.

[0028] In one embodiment of the present invention, the chute device further comprises a first support 3 and a second support 4, wherein the first support 3 is fixed to the buffer tank 5 for supporting the buffer tank 5, and the second support 4 is fixed to the buffer box 7 for supporting the buffer box 7. Figure 1 As shown, the first support 3 can be welded below the buffer groove 5, and the second support 4 can be welded below the buffer box 7. The first support 3 and the buffer groove 5, and the second support 4 and the buffer box 7 can also be connected in other ways.

[0029] Figure 3 Schematic diagram of the main view of the linear chute in the present invention, as shown in Figure 3As shown, the linear chute 1 includes a top plate 108, a first bottom plate 102, a buffer tank 5, a sixth bottom plate 107 and a pair of side plates 101 arranged opposite to each other, the side plates 101 connect the top plate 108 and the first bottom plate 102, the top plate 108 and the buffer tank 5, the top plate 108 and the sixth bottom plate 107, and the buffer tank 5 is connected between the first bottom plate 102 and the sixth bottom plate 107. The first flange 109 and the second flange 110 are fixed at both ends of the linear chute 1, respectively, and the linear chute 1 can be connected to the feeding equipment through the first flange 109, so that the conveying medium enters the main body of the linear chute 1 through the first flange 109 for flow and transportation, and flows out of the linear chute 1 through the second flange 110.

[0030] Since the linear chute 1 usually needs to be lined with rubber or coated with other anti-corrosion and wear-resistant materials to protect the linear chute, preferably, a first opening 113 is cut in the middle of the top plate 108, and the rubber lining or coating construction work is carried out through the first opening 113, which is convenient for workers to operate and construct. Furthermore, the linear chute 1 also includes a cover plate 111, which is located on the outer surface of the top plate 108, and the cover plate 111 and the top plate 108 are detachably connected, for example, the cover plate 111 and the top plate 108 are connected by bolts. The cover plate 111 completely covers the first opening 113 to achieve sealing. Preferably, a rubber pad 112 is provided between the cover plate 111 and the top plate 108, and the rubber pad 112 plays a role in strengthening the seal to prevent the conveying medium from splashing and overflowing in the linear chute.

[0031] According to the requirements of process design, when using the chute device of the present invention to transmit medium, multiple feed ports may be required to allow the conveying medium to enter the chute device, or the same or different conveying media of multiple feeding devices may be required to enter the chute device from different feed ports and merge before transportation. Preferably, a first opening 113 is cut in the middle of the top plate 108, and the linear chute 1 can be connected with other feeding devices through the first opening 113, so that the conveying medium enters the linear chute 1 through the first opening 113 for transportation, and the buffer trough 5 is located below the first opening 113, so that when the conveying medium enters the linear chute 1 through the first opening 113, it can fall into the buffer trough 5 in advance, accumulate in the buffer trough 5 to form a first buffer zone, and reduce the impact of the conveying medium on the wall of the linear chute.

[0032] Furthermore, when the feeding device is connected to the first opening 113, a chute buffer structure can be connected between the feeding device and the first opening 113, so that the conveying medium is buffered by the chute buffer structure before entering the chute device, so as to further reduce the impact of the conveying medium on the wall of the chute device, reduce damage to the chute device, and improve the safety and reliability of the chute device. Figure 4 Schematic diagram of the structure of the linear chute embodiment of the present invention, as shown in Figure 4As shown, the linear chute also includes a chute buffer structure, which includes: a feed port 81, a first pipe 82, a second pipe 83 and a discharge port 84, wherein the feed port 81 is arranged at the first end of the first pipe 82, the second end of the first pipe 82 is fixedly connected to the top plate 108, the first end of the second pipe 83 passes through the top plate 108 and is provided with a discharge port 84, and the second end of the second pipe 83 is connected to the wall surface of the first pipe 82. Further, a cover plate 111 is arranged on the outer surface of the top plate 108, then the second end of the first pipe 82 is fixedly connected to the cover plate 111, and a rubber pad 112 can be arranged between the cover plate 111 and the top plate 108 for sealing. The chute buffer structure is connected to other feeding equipment through the feed port 81, and is connected to the main body of the linear chute through the first opening 113 (the main body of the linear chute includes the top plate 108, the first bottom plate 102, the buffer tank 5, the sixth bottom plate 107 and a pair of side plates 101 arranged oppositely). The conveying medium enters the main body of the linear chute from the feed port 81, accumulates in the first pipe 82 to form a third buffer zone 85, and the subsequent conveying medium impacts the conveying medium in the third buffer zone 85 and enters the second pipe 83, and flows into the main body of the linear chute through the discharge port 84. The third buffer zone 85 dissipates the energy of the conveying medium, so that the conveying medium entering the main body of the linear chute through the second pipe 83 is more stable, and avoids directly impacting the wall of the main body of the linear chute. The buffer tank 5 is located below the discharge port 82, the first pipe 82 can be placed vertically, and the second pipe 83 can be placed tilted, and the tilt angle is adjusted according to the tilt angle of the main body of the linear chute to ensure that the conveying medium passing through the second pipe 83 smoothly enters the main body of the linear chute. The conveying medium entering the main body of the linear chute through the discharge port 82 is accumulated in the buffer tank 5 in advance, and the subsequent conveying medium impacts the conveying medium in the buffer tank 5 and flows along the wall of the main body of the linear chute.

[0033] It should be noted that multiple first openings 113 can be cut along the length direction of the main body of the linear chute to connect different feeding devices, so that multiple identical or different conveying media can be transported after merging in the linear chute 1, and a chute buffer structure can be connected between each feeding device and the corresponding first opening.

[0034] In the present invention, when the conveying medium is transported in the linear chute 1, it accumulates in the buffer trough 5 to form a first buffer zone, and the subsequent conveying medium is buffered by the first buffer zone in the linear chute 1, thereby reducing the potential energy of movement. The buffer trough 5 formed in the linear chute 1 is concave, and the buffer trough 5 protrudes outward from the first bottom plate 102 and the sixth bottom plate 107 of the linear chute 1, so as to facilitate the accumulation of the conveying medium in the buffer trough 5. The buffer trough 5 can be in a square, rectangular or trapezoidal shape. Preferably, the buffer trough 5 includes a second bottom plate 103, a third bottom plate 104 and a fourth bottom plate 105, the side edges of the second bottom plate 103 are respectively connected to the first bottom plate 102, a pair of side plates 101 and the third bottom plate 104, the side edges of the fourth bottom plate 105 are respectively connected to the third bottom plate 104, a pair of side plates 101 and the sixth bottom plate 107, and the side edges of the third bottom plate 104 are respectively connected to the second bottom plate 103, the fourth bottom plate 105 and the pair of side plates 101. The second bottom plate 103 , the third bottom plate 104 and the fourth bottom plate 105 form a concave structure, and the height of the fourth bottom plate 105 is smaller than that of the second bottom plate 103 , so that the conveying medium flows along the linear chute 1 under the action of gravity.

[0035] Preferably, the linear chute 1 further comprises a fifth bottom plate 106, the fifth bottom plate 106 is horizontally arranged, and the sides of the fifth bottom plate 106 are respectively connected to the pair of side plates 101, the fourth bottom plate 105 and the sixth bottom plate 107. After being buffered by the first buffer zone, the conveying medium flows along the fifth bottom plate 106, and a steady flow area 6 is formed on the fifth bottom plate 106. After the transition of the steady flow area 6, the conveying medium flows smoothly along the sixth bottom plate 107 in the linear chute 1.

[0036] In one embodiment of the present invention, the third bottom plate 104 and the fifth bottom plate 106 are arranged horizontally, and the first bottom plate 102 and the sixth bottom plate 107 have a certain inclination angle with the horizontal direction. The size of the inclination angle is determined according to process calculations to facilitate the smooth flow of the conveying medium in the linear chute 1 under the action of gravity.

[0037] In the present invention, the diverting chute 2 can be connected to the straight chute 1 or the diverting chute 2. The transmission direction of the conveying medium can be adjusted through the diverting chute 2 to play the role of bending the pipe and prevent the bent pipe from being easily damaged by scouring for a long time. Figure 5 is a schematic diagram of the main view of the diverting chute in the present invention, Figure 6 : is a left side schematic diagram of the diverting chute in the present invention, such as Figure 5 and Figure 6As shown, the diverting chute 2 includes a first chute 21, a second chute 22 and a buffer box 7. The conveying medium accumulates in the buffer box 7 to form a second buffer zone. After the conveying medium is transported by the linear chute 1, the second buffer zone can further reduce the kinetic potential energy of the conveying medium. Preferably, the two adjacent surfaces of the buffer box 7 are respectively provided with a second opening 215 and a third opening 216, and the position of the third opening 216 is lower than the position of the second opening 215, so that the conveying medium flows through the first chute 21, the buffer box 7 and the second chute 22 in sequence under the action of gravity, and flows smoothly to the next device or chute through the second chute 22. The first chute 21 is connected to the buffer box 7 through the second opening 215, and the second chute 22 is connected to the buffer box 7 through the third opening 216. The first chute 21 and the second chute 22 are at a certain angle, for example, they can be at a 90-degree angle, so that the conveying medium changes the conveying direction after passing through the diverting chute 2.

[0038] In the present invention, the buffer box 7 can be square, rectangular or trapezoidal, etc., as long as the conveying medium can be accumulated in the buffer box 7 to form a second buffer zone. In addition, the transmission direction of the conveying medium can be adjusted by the difference in the relative positions of the first chute 21 and the second chute 22 with the buffer box 7. Preferably, the buffer box 7 is square, including a first side plate 201, a second side plate 202, a third side plate 203, a fourth side plate 204, an upper top plate 206 and a lower bottom plate 205, and the second opening 215 and the third opening 216 are respectively arranged on two adjacent sides of the buffer box 7, for example, the second opening 215 is cut at the upper part of the fourth side plate 204, the third opening 216 is cut at the middle part of the first side plate 201, the first chute 21 is welded at the second opening 215, and the second chute 22 is welded at the first opening. The first chute 21 and the second chute 22 each include two trapezoidal side plates and two rectangular plates. One end of the first chute 21 and the second chute 22 are respectively fixed to the two side surfaces of the buffer box 7, and the other end is respectively fixed to the third flange 210 and the fourth flange 214. The first chute 21 can be connected to other linear chutes 1 or diverting chutes 2 through the third flange 210, and the second chute 22 can be connected to other linear chutes 1 or diverting chutes 2 through the fourth flange 214. Figure 5 and Figure 6As shown, the first chute 21 includes a first rectangular plate 208, a second rectangular plate 209, a third flange 210 and two first trapezoidal side plates 207, wherein the first rectangular plate 208 and the second rectangular plate 209 are arranged opposite to each other, the two first trapezoidal side plates 207 are arranged opposite to each other, and the third flange 210 is welded to the end of the first chute 21; the second chute 22 includes a third rectangular plate 212, a fourth rectangular plate 213, a fourth flange 214 and two second trapezoidal side plates 211, wherein the third rectangular plate 212 and the fourth rectangular plate 213 are arranged opposite to each other, the two second trapezoidal side plates 211 are arranged opposite to each other, and the fourth flange 214 is welded to the end of the second chute 22. Moreover, the first rectangular plate 208, the second rectangular plate 209, the third rectangular plate 212 and the fourth rectangular plate 213 are all arranged at a certain angle with the horizontal plane. Preferably, the inclination angle of the first chute 21 and the second chute 22 relative to the horizontal plane is the same as the inclination angle of the linear chute 1 relative to the horizontal plane, so as to facilitate the smooth flow of the conveying medium in the linear chute 1 and the turning chute 2.

[0039] Similarly, when the medium is transmitted by the chute device of the present invention according to the process design requirements, multiple feed ports are required, or the same or different conveying media of multiple feeding devices are required to enter the chute device from different feed ports and merge before transportation, the fourth opening can be cut on the upper top plate 206 to increase the feed ports, and the diverting chute and other feeding devices are connected through the fourth opening. The conveying medium enters the diverting chute through the fourth opening, passes through the buffer of the diverting chute, and enters the next process or other linear chute or diverting chute for transportation. For example, the flange connection between the feeding device and the diverting chute is achieved by welding a steel pipe at the fourth opening and welding a flange at the other end of the steel pipe.

[0040] In one embodiment of the present invention, the linear chute 1 is flange-connected with the linear chute 1 or the turning chute 2. For example, the two ends of the linear chute 1 are respectively fixed to the first flange 109 and the second flange 110, and the linear chute 1 is flange-connected with the first chute 21 or the second chute 22.

[0041] In order to further enhance the buffering effect of the buffer trough and the buffer box on the conveying medium, an elastic member and a buffer plate can be arranged in the buffer trough or the buffer box. For example, taking the buffer trough as an example, one end of the elastic member is fixed on the third bottom plate 104 of the buffer trough 5, and the other end is fixed with a buffer plate, and the horizontal height of the buffer plate is lower than the height of the first bottom plate 102. When the conveying medium flows along the linear chute 1 under the action of gravity or enters the linear chute 1 from the first opening 113, it falls on the buffer plate in advance. Due to the action of the elastic member, the conveying medium has a buffering effect, the kinetic potential energy of the conveying medium is reduced, and the transitional splashing of the conveying medium in the buffer trough is avoided.

[0042] In the present invention, the linear chute 1 and the diverting chute 2 can be arranged and used in any combination. There are multiple linear chutes 1 and diverting chutes 2, and each linear chute 1 is connected to the linear chute 1 and / or the diverting chute 2, that is, both ends of the linear chute 1 can be connected to the linear chute 1, or both connected to the diverting chute 2, or one end is connected to the linear chute 1 and the other end is connected to the diverting chute 2. Similarly, both ends of the diverting chute 2 can be arbitrarily connected to the linear chute 1 or the diverting chute 2. According to the process design flow, the linear chute 1 or the diverting chute 2 are arranged at different positions.

[0043] In one embodiment of the present invention, the linear chute 1 and the diverting chute 2 are both made of steel, and a rubber layer is lined inside the linear chute 1 and the diverting chute 2 to further increase the corrosion resistance and wear resistance of the chute device.

[0044] The working process of the chute device of the present invention is described in detail below by taking slurry as the conveying medium.

[0045] According to process calculations, the linear chute 1 is arranged at an inclination angle that satisfies the slurry self-flow conditions. After a long distance of movement in the linear chute 1, the slurry gradually increases its potential energy. When it enters the first buffer zone, it falls into the first buffer zone under the action of gravity, forming a material accumulation layer in the first buffer zone. The material accumulation layer can resist the impact of the slurry and protect the third bottom plate 104 of the linear chute 1. At the same time, it reduces the slurry's potential energy. After the transition of the steady flow zone 6, the slurry continues to flow downward smoothly in the linear chute 1. The turning chute 2 plays the role of bending the pipe, but avoids the disadvantage that the bend pipe is easily damaged by long-term scouring. Before entering the diverting chute 2, the slurry has been energy-dissipated by the first buffer zone and the steady flow zone 6. Therefore, the slurry entering the diverting chute 2 will not present a large parabolic motion trajectory, which is beneficial to reducing the size of the diverting chute. The slurry falls into the second buffer zone and forms an accumulation layer in the second buffer zone. The accumulation layer can resist the impact of the slurry and protect the lower bottom plate 205 of the diverting chute 2. At the same time, the kinetic potential energy of the slurry is reduced. The slurry enters the second chute 22 of the diverting chute 2 through overflow to further supply the next equipment.

[0046] The reduction of the slurry flow rate in the linear chute 1 reduces the lateral load force of the chute, thereby reducing the lateral load force of the first support 3 below. Since the diverting chute 2 is not subjected to the lateral impact of the slurry, this greatly reduces the lateral load generated by the diverting chute 2, thereby reducing the lateral load force of the second support 4 below. Since many chutes are suspended in mid-air, a bracket or hanger is required to support the chute. When designing a bracket or hanger, the lateral load is an important technical indicator. The reduction of the lateral load generated by the chute device itself is greatly beneficial to the design of the bracket or hanger.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
