It not only directly affects the quality, transportation cost and storage conditions of the product, but also has a far-reaching impact on the subsequent smelting and deep processing. However, the dehydration and drying operation of the selected molybdenum concentrate particles still has the following defects: when the molybdenum concentrate particles are dehydrated, the molybdenum concentrate particles are mostly accumulated at the bottom of the dehydration cylinder under the action of gravity. This leads to the need to dry and heat the molybdenum concentrate particles for a long time to ensure that the molybdenum concentrate particles can be fully dried during the drying process of the molybdenum concentrate particles, resulting in low drying efficiency of the molybdenum concentrate particles. If the dehydrated molybdenum concentrate particles are poured out and dried again, not only two devices are required, but also the drying process of the molybdenum concentrate particles is increased.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6A molybdenum concentrate particle dehydration and drying device comprises: a dehydration and drying cylinder 1, the dehydration and drying cylinder 1 is in a rectangular cylinder shape, the outer wall of the dehydration and drying cylinder 1 is fixedly sleeved with a heat preservation barrel 6 with a circular cavity structure through a connecting frame 7, and heat preservation materials are filled between the heat preservation barrel 6 and the dehydration and drying cylinder 1, the top of the heat preservation barrel 6 is provided with a rectangular through groove, and the bottom is provided with a straight discharge groove 60, an inlet and outlet opening and closing group 10 is installed between the dehydration and drying cylinder 1 and the rectangular through groove and the straight discharge groove 60, and a A centrifugal filter bag 2 is made of a high temperature resistant material.

The rotating frame 3 consists of a rotating tube 30 rotatably connected to the side wall of the dehydration and drying tube 1 and a connecting column 31 connected to the end of the rotating tube 30 and perpendicular to its axis. The rotating tube 30 rotates through the insulation barrel 6.

[0036] See also Figure 6 The inlet and outlet opening and closing group 10 includes the upper ends of the two side walls of the dehydration and drying cylinder 1 arranged along its length direction and the closed door panels 101 that are slidably connected to the rectangular through grooves. The heat preservation barrel 6, the dehydration and drying cylinder 1 and the connecting frame 7 are all provided with rectangular through grooves that are slidably connected to the corresponding closed door panels 101. The upper and lower corresponding closed door panels 101 are connected by connecting plates. The lower ends of the two inner walls of the dehydration and drying cylinder 1 arranged along its length direction are installed with inclined guide plates 102. The two inclined guide plates 102 are in an eight-shaped shape with a small diameter facing downward. A vertical guide plate 61 is installed between the lower end of the inclined guide plate 102 and the straight-line discharge groove 60.

[0037] Insulation material is filled between the insulation barrel 6 and the dehydration and drying cylinder 1, so that the temperature in the dehydration and drying cylinder 1 is kept warm when the drying mechanism 5 dries and heats the molybdenum concentrate particles. Closing door panels are installed on the dehydration and drying cylinder 1 and the insulation barrel 6, so as to achieve a double insulation effect. After the molybdenum concentrate particles enter the centrifugal filter bag 2, the upper ends of the insulation barrel 6 and the dehydration and drying cylinder 1 are closed by the closing door panel 101 to avoid water splashing during the centrifugal dehydration process.

[0038] See also Figure 3 The upper and lower ends of the two connecting columns 31 are jointly installed with a centrifugal dehydration mechanism 4 for driving the centrifugal filter bag 2 to rotate and centrifugally dehydrate the molybdenum concentrate; the side walls of the two rotating cylinders 30 are jointly provided with a drying mechanism 5 for drying the dehydrated molybdenum concentrate particles in the centrifugal filter bag 2 in a horizontal state.

[0039] See also Figure 1 , Figure 3 , Figure 5 and Figure 6The centrifugal dehydration mechanism 4 includes two support frames 40, which are rotatably mounted on the upper and lower funnel tubes 20, and the two ends of the support frames 40 are respectively connected to the two connecting columns 31. The two support frames 40 are both equipped with a blocking group 41 for blocking the corresponding funnel tube 20. The support frame 40 located on the upper side is provided with a rotating drive group 42 for driving the centrifugal filter bag 2 to rotate and centrifugally dehydrate the molybdenum concentrate particles.

[0040] See also Figure 3 , Figure 6 and Figure 7 The drying mechanism 5 includes two fixed frames 50, which are parallel to the axis of the funnel cylinder 20. The middle parts of both sides of the fixed frames 50 arranged along the width direction are equipped with connecting pipes 51 connected to the rotating cylinder 30. The upper and lower ends of the fixed frames 50 are connected to the inner wall of the dehydration and drying cylinder 1 through a rotating support group 52. A drying and heating group 53 is slidably connected in the fixed frame 50. A limiting rod 54 for limiting the drying and heating group 53 is installed on the end surface of the fixed frame 50 away from the centrifugal filter bag 2.

[0041] The sealing group 41 located on the upper side opens the funnel tube 20 located on the upper side, and then pours the selected molybdenum concentrate particles into the centrifugal filter bag 2, and then closes the funnel tube 20 located on the upper side, and then drives the centrifugal filter bag 2 to rotate through the rotary drive group 42, so that the water on the molybdenum concentrate particles is discharged from the centrifugal filter bag 2 under the action of the centrifugal rotating force. When the centrifugal dehydration stops for a period of time, one of the rotating cylinders 30 is driven to rotate by an external driving source, and the rotating cylinder 30 drives the other rotating cylinder 30 to rotate synchronously under the connection between the connecting column 31 and the support frame 40. When the two rotating cylinders 30 rotate, they drive the centrifugal filter bag 2 containing the molybdenum concentrate particles after centrifugal dehydration to rotate, and at the same time, the fixed frame 50 is connected to the connecting pipe Under the connection of 51, the drying and heating group 53 rotates synchronously with the rotating drum 30, and the drying and heating group 53 located at the lower side supports the centrifugal filter bag 2 during rotation, thereby reducing the damage of the molybdenum concentrate particles to the centrifugal filter bag 2, until the centrifugal filter bag 2 rotates horizontally, and the centrifugal filter bag 2 is flattened on the drying and heating group 53 located at the lower side under the gravity of the molybdenum concentrate particles, thereby increasing the dispersion area of ​​the molybdenum concentrate particles in the centrifugal filter bag 2 and the heating area of ​​the molybdenum concentrate particles on the drying and heating group 53, so that the upper and lower drying and heating groups 53 can quickly dry and heat the molybdenum concentrate particles in the centrifugal filter bag 2, greatly improving the drying efficiency of the molybdenum concentrate particles. It should be noted that after one of the rotating drums 30 rotates through the dehydration and drying drum 1, a rotating gear is fixedly sleeved, and the outer wall of the dehydration and drying drum 1 is rotatably connected to a rotating shaft, and a rotating gear meshing with a rotating ring gear is fixedly sleeved on the rotating shaft, and the rotating shaft is connected to an external motor, wherein the rotating shaft, the rotating ring gear, the rotating gear and the external motor are not shown in the figure.

[0042] Then, the molybdenum concentrate particles in the centrifugal filter bag 2 are heated and dried by the upper and lower drying and heating groups 53. After the molybdenum concentrate particles are dried, the rotating frame 3 drives the centrifugal filter bag 2 to rotate and return to a vertical state. At this time, the funnel tube 20 located on the lower side is opened to discharge the dried molybdenum concentrate particles.

[0043] See also Figure 4 and Figure 5 The blocking group 41 includes a fixed plate 410 installed on the support frame 40, and a sliding block 412 that slides up and down is connected to the fixed plate 410. A sliding groove 413 is opened on the fixed plate 410, and a push spring 414 is installed between the sliding groove 413 and the sliding block 412. An L-shaped lifting rod 415 is slidably connected to the sliding block 412, and the end of the lifting rod 415 away from the sliding block 412 is rotatably connected to a conical column 416 concentric with the funnel tube 20. Under the push of the push spring 414, the side wall of the conical column 416 is tightly attached to the inner wall of the funnel tube 20 close to the centrifugal filter bag 2, and the inner wall of the dehydration and drying tube 1 is installed with a push drive component that pushes the lifting rod 415 to move.

[0044] When it is necessary to pour the molybdenum concentrate particles into the centrifugal filter bag 2 or pour out the dried molybdenum concentrate particles, the corresponding lifting rod 415 is pushed by the push drive assembly to drive the sliding block 412 to move, so that the lifting rod 415 pushes the conical column 416 to move into the centrifugal filter bag 2, thereby opening the corresponding funnel tube 20.

[0045] See also Figure 5 The rotating drive group 42 includes a fixed ring 420 fixedly sleeved on the outer wall of the upper funnel tube 20. The fixed ring 420 is fixedly sleeved at the small diameter in the middle of the funnel tube 20. The fixed ring 420 is T-shaped, and the small diameter section of the fixed ring 420 rotates through the support frame 40. A driving gear ring is fixedly sleeved on the fixed ring 420. A driving shaft 422 is rotatably connected to the support frame 40. A driving gear 423 meshing with the driving gear ring is fixedly sleeved on the driving shaft 422 for transmission.

[0046] The driving shaft 422 is connected to an external driving motor, and the external driving motor drives the driving shaft 422 to rotate, so that the driving shaft 422 drives the driving gear 423 to rotate, and the driving gear 423 drives the funnel barrel 20 located on the upper side to rotate through its meshing transmission with the driving gear ring. The funnel barrel 20 located on the upper side drives the centrifugal filter bag 2 and the funnel barrel 20 located on the lower side to rotate, thereby centrifugally dehydrating the molybdenum concentrate particles in the centrifugal filter bag 2.

[0047] See also Figure 3Both ends of the support frame 40 are installed with arc-shaped bars 401, and the inner wall of the dehydration and drying cylinder 1 is provided with a limiting support groove 402 which is slidably connected to the arc-shaped bar 401. The sliding cooperation between the arc-shaped bar 401 and the limiting support groove 402 increases the stability of the support frame 40.

[0048] See also Figure 6 and Figure 7 The drying and heating group 53 includes an installation box 530, which is slidably connected in the fixed frame 50. The installation box 530 and the fixed frame 50 are connected by a reset spring 531. A heating plate 532 is installed on the end surface of the installation box 530 close to the centrifugal filter bag 2. The heating plate 532 is provided with a plurality of inclined grooves 533 evenly arranged along its length. The inclined grooves 533 and the heating components in the heating plate 532 are arranged in an alternating manner. The heating components are heating tubes. The inclined grooves 533 penetrate the heating plate 532 and are connected to the installation box 530. When the installation box 530 is in a vertical state, the inclined grooves 533 are inclined downward, which does not affect the inclined grooves. The blowing effect of the groove 533 on the centrifugal filter bag 2 can also prevent the water thrown out when the centrifugal filter bag 2 rotates to centrifugally dehydrate the molybdenum concentrate particles from entering the installation box 530 from the inclined groove 533. The side walls of the fixed frame 50 and the installation box 530 are both installed with connecting grooves 534, and the corresponding two connecting grooves 534 are connected. The connecting groove 534 on the fixed frame 50 is connected to one of the connecting pipes 51, and the wind source enters from the rotating cylinder 30 connected to the connecting pipe 51 connected to the connecting groove. The wire enters the corresponding connecting pipe 51 through the other rotating cylinder 30 and is connected to the heating plate 532, thereby completing the electrical connection of the heating plate 532.

[0049] After the fixed frame 50 rotates to a horizontal state, the upper and lower mounting boxes 530 are pushed to move by driving the push drive assembly of the lifting rod 415. The mounting box 530 on the upper side drives the heating plate 532 connected thereto to move toward the centrifugal filter bag 2, and the mounting box 530 on the lower side pushes the centrifugal filter bag 2 to move upward until the heating plates 532 on the mounting boxes 530 on both sides are in contact with the centrifugal filter bag 2. During the movement of the upper and lower mounting boxes 530, the centrifugal filter bag 2 is flattened, so that the molybdenum concentrate particles in the centrifugal filter bag 2 are more dispersed, so that the heating plate 532 can dry and heat the molybdenum concentrate particles more fully and quickly.

[0050] Then, an external wind source (such as a fan) is used to deliver wind into the installation box 530. The wind source cooperates with the heating plate 532 through the chute 533 to dry and heat the centrifugal filter bag 2 and the molybdenum concentrate particles in the centrifugal filter bag 2, thereby greatly improving the drying efficiency of the molybdenum concentrate particles.

[0051] See also Figure 3 , Figure 4 , Figure 5 and Figure 6The push driving assembly includes two lifting chutes 430, which are opened on one of the two inner walls of the dehydration and drying cylinder 1 arranged along the length direction. A lifting plate 431 is slidably connected in the lifting chute 430, and a plurality of push rods 432 evenly arranged along its length direction are installed on the lifting plate 431. The push rods 432 are L-shaped, and one of the push rods 432 is aligned with the lifting rod 415.

[0052] The two lifting plates 431 are respectively connected to two electric slides to drive each to slide. When the push drive assembly drives the sealing group 41 to open the funnel tube 20, the corresponding lifting plate 431 slides, thereby driving the corresponding push rod 432 to move. When the push rod 432 aligned with the lifting rod 415 collides with the lifting rod 415, the lifting rod 415 is squeezed to drive the sliding block 412 to move along the sliding groove. The lifting rod 415 drives the conical column 416 to move, thereby opening the corresponding funnel tube 20.

[0053] When the centrifugal filter bag 2 and the installation box 530 are rotated to a horizontal state, when the push driving assembly pushes the installation box 530 to move, the lifting plate 431 drives the push rod 432 to move, and multiple push rods 432 simultaneously contact the side wall of the installation box 530, thereby pushing the installation box 530 to move. The push driving assembly can drive the sealing group 41 to open the funnel tube 20, and can also drive the installation box 530 to move, achieving the effect of one machine serving two purposes.

[0054] See also Figure 3 The push rod 432 located at the lower side is in an L-shaped column, so as to prevent the molybdenum concentrate particles discharged after drying from accumulating on the push rod 432.

[0055] See also Figure 3 The rotating support group 52 includes rotating rods 520 symmetrically arranged along the length direction of the fixed frame 50, which are installed on both side walls arranged along the width direction of the fixed frame 50. The side wall of the dehydration and drying cylinder 1 is provided with an arc guide groove 521 slidably connected to the rotating rod 520. The arc guide groove 521 and the limit support groove 402 are concentric with the rotating cylinder 30. The sliding cooperation between the arc guide groove 521 and the rotating rod 520 increases the stability of the connection and rotation of the centrifugal dehydration mechanism 4 and the drying mechanism 5.

[0056] See also Figure 1-Figure 7 The present invention also provides a method for dehydrating and drying molybdenum concentrate particles, comprising the following steps: S1. Pouring material in: the plugging group 41 located on the upper side opens the funnel tube 20 located on the upper side, and then pours the selected molybdenum concentrate particles into the centrifugal filter bag 2, and then the plugging group 41 located on the upper side closes the funnel tube 20 located on the upper side.

[0057] S2. Centrifugal dehydration: The centrifugal filter bag 2 is driven to rotate by the rotary drive group 42, so that the water on the molybdenum concentrate particles is discharged from the centrifugal filter bag 2 under the action of the centrifugal rotation force.

[0058] S3. Rotate and lay down: When the centrifugal dehydration stops for a period of time, one of the rotating drums 30 is driven to rotate by an external driving source, and the rotating drum 30 drives the other rotating drum 30 to rotate synchronously under the connection between the connecting column 31 and the support frame 40. When the two rotating drums 30 rotate, the centrifugal filter bag 2 containing the molybdenum concentrate particles after centrifugal dehydration is driven to rotate. At the same time, the fixed frame 50 rotates synchronously with the rotating drum 30 under the connection of the connecting pipe 51, and the drying and heating group 53 rotates synchronously. The drying and heating group 53 located on the lower side supports the centrifugal filter bag 2 when rotating until the centrifugal filter bag 2 rotates to a horizontal state. The centrifugal filter bag 2 is flattened on the drying and heating group 53 located on the lower side under the gravity of the molybdenum concentrate particles.

[0059] S4. Drying and heating: After the fixed frame 50 rotates to a horizontal state, the upper and lower mounting boxes 530 are pushed to move by driving the push drive assembly of the lifting rod 415, and the mounting box 530 on the upper side drives the heating plate 532 connected thereto to move toward the centrifugal filter bag 2, and the mounting box 530 on the lower side pushes the centrifugal filter bag 2 to move upward until the heating plates 532 on the mounting boxes 530 on both sides of the upper and lower sides are in conflict with the centrifugal filter bag 2.
