Description

Technical Field

[0001] The invention belongs to the technical field of sodium molybdate production, and particularly relates to a centrifugal separation device for sodium molybdate production. Background Art

[0002] Sodium molybdate is a white rhombus crystal. Sodium molybdate can be produced by oxidizing and roasting molybdenum concentrate to produce molybdenum trioxide, then leaching with liquid alkali to produce sodium molybdate solution, and then filtering, concentrating, cooling, centrifuging and drying to obtain the product.

[0003] At present, in the production process of sodium molybdate, sodium molybdate crystals are generally separated by concentration, and then separated by filtration after crystallization.

[0015] The present invention has the following beneficial effects: 1. The process of the first spur gear rotating one circle can be divided into three processes of 0-90°, 90-180° and 180-360°. The process of 0-180° is integrated into one, that is, sodium molybdate can be thrown out of the centrifugal cylinder from the first through hole. In the process of 180-360°, the first through hole and the second through hole are completely staggered, so that sodium molybdate cannot be thrown out of the centrifugal cylinder from the first through hole, so that the sodium molybdate solution is intermittently thrown out of the centrifugal cylinder, which paves the way for the subsequent formation of a liquid film and crystallization of the sodium molybdate solution after being thrown out.

[0016] 2. The present invention allows the sodium molybdate solution in the centrifugal drum to be thrown onto the fabric in the liquid film assembly during the rotation of the centrifugal drum, so that the thrown sodium molybdate solution forms a liquid film on the fabric, and the sodium molybdate solution on the fabric is heated by using a heating plate in the liquid film assembly, thereby accelerating the crystallization of sodium molybdate, and causing the crystallized sodium molybdate to adhere to the fabric. After the sodium molybdate solution is crystallized, the winding roller winds up the traction rope, and the traction force of the traction rope drives the arc-shaped support plate to move toward the first collecting box, so that the arc-shaped support plate pulls and drives the fabric to be close to the first collecting box, and with the movement of the fabric, the sodium molybdate crystals on the fabric are scraped off by the first collecting box and collected inside. In summary, the sodium molybdate solution is thrown out on the fabric to form a large-scale liquid film, which can be quickly crystallized after being heated after formation, and then is scraped off and collected in a concentrated manner, so that the rate of separation and crystallization of sodium molybdate is faster, thereby improving the separation and crystallization efficiency of sodium molybdate.

[0017] 3. The present invention injects the sodium molybdate solution into the centrifugal cylinder through the injection tube, and connects the guide channel with the first through hole, so that during the centrifugation process, the sodium molybdate solution always fills the guide channel under the pressure of the load-bearing plate, ensuring that the sodium molybdate solution is evenly centrifuged out when the through hole is opened.

[0018] 4. The present invention drives the arc plate to rotate together with the centrifugal cylinder during the rotation of the centrifugal cylinder, so that the arc plate further drives the annular plate to rotate. At the same time, the reciprocating lifting and pulling of the push-pull rod drives the arc plate to move up and down reciprocatingly, so that the arc plate drives the annular plate and the conical plate to move up and down. During the up and down movement of the conical plate, the sodium molybdate crystals on the fabric are continuously scraped, so that a part of the sodium molybdate crystals on the fabric fall off and are collected in the second collecting box. The arrangement of the conical plate and the partition ensures that after the sodium molybdate solution is thrown out, a small part of the sodium molybdate solution drips on the conical plate, and this part of the sodium molybdate solution will flow along the surface of the conical plate onto the fabric. The blocking effect of the partition can prevent the sodium molybdate solution from deviating from the direction of flowing toward the fabric during the flow on the conical plate, thereby avoiding that part of the sodium molybdate solution dripping on the conical plate cannot flow onto the fabric, causing waste, and ultimately affecting the total amount of sodium molybdate after crystallization.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating shaft 2120 is rotatably connected to one side of the rotating shaft 2120, and a third circular plate 2121 is fixedly connected to the end of the rotating shaft 2120. A three-arc notch 2122 is provided on the peripheral side of the third circular plate 2121, and a U-shaped groove 2123 adapted to a first push rod 2118 and a second push rod 2119 is provided between two adjacent three-arc notches 2122 (the first push rod 2118 and the second push rod 2119 are arranged at an angle of 90°, and the second push rod 2119 is slidably fitted in the corresponding U-shaped groove 2123 at an initial position, and the first push rod 2118 and the U-shaped groove 2123 away from the second push rod 2119 are arranged at an angle of 90°, such as; Figure 7 As shown), the three arc-shaped notches 2122 are internally hingedly connected with a push-pull rod 2124, and the push-pull rod 2124 and the arc-shaped plate 207 are hingedly connected.

[0042] The operation process of this embodiment is as follows: the first motor 201 and the second motor 2101 are started synchronously (the models and power sizes of the first motor 201 and the second motor 2101 are the same), the driving end of the first motor 201 drives the first rotating shaft 202 to rotate, so that the first rotating shaft 202 drives the centrifugal drum 204 to rotate, and synchronously, the driving end of the second motor 2101 drives the first pulley 2102 to rotate, so that the first pulley 2102 drives the second pulley 2104 to rotate through the first belt, and the second pulley 2104 drives the second rotating shaft 2103 and the first bevel gear 2105 to rotate, so that the first bevel gear 2105 drives the second bevel gear 2108 meshing therewith to rotate synchronously, and further the second bevel gear 2108 drives the first rotating rod 2107 and the third pulley 2109 to rotate, and the third pulley 2109 drives the fourth pulley 2112 to rotate through the second belt The fourth pulley 2112 drives the second rotating rod 2111, the first spur gear 2114, the first circular plate 2113 and the first push rod 2118 to rotate, and during the rotation of the first spur gear 2114, the second spur gear 2116 is driven to rotate synchronously, so that the second spur gear 2116 drives the third rotating rod 2115, the second circular plate 2117 and the second push rod 2119 to rotate (because the first spur gear 2114 drives the second spur gear 2116 to rotate, the rotation directions of the first push rod 2118 and the second push rod 2119 are opposite), the arc plate 207 is tightly fitted with the lower end of the slide groove 205 in the initial state, and the second through hole 208 on the arc plate 207 is misaligned with the first through hole 206. At this time, the centrifugal cylinder 204 cannot throw the sodium molybdate solution out of the through hole 1 206. At the same time, the first push rod 2118 and the second push rod 2119 are set at a 90° angle in the initial position (such as Figure 7 As shown in the figure, the U-shaped groove 2123 corresponding to the second push rod 2119 is slidably matched, and the first push rod 2118 is set at a 90° angle with the U-shaped groove 2123 away from the second push rod 2119, and the first spur gear 2114 rotates 90° clockwise, so that the first spur gear 2114 drives the second rotating rod 2111, the first circular plate 2113 and the first push rod 2118 to rotate 90° clockwise. At the same time, the first spur gear 2114 drives the meshing second spur gear 2116 to rotate counterclockwise by 90°, so that the second spur gear 2116 drives the third rotating rod 2115, The second circular plate 2117 and the second push rod 2119 rotate counterclockwise by 90°, and the second push rod 2119 pushes the U-shaped groove 2123 on the third circular plate 2121, thereby driving the third circular plate 2121 to rotate clockwise by 90°, so that the push-pull rod 2124 on the third circular plate 2121 is lifted, thereby driving the arc plate 207 to move upward along the slide groove 205, so that the second through hole 208 on the arc plate 207 gradually completely overlaps with the first through hole 206 from being completely misaligned, and the sodium molybdate solution inside the centrifugal cylinder 204 can be thrown out during the centrifugal process through the rotation of the centrifugal cylinder 204; At this time, the U-shaped groove 2123 on the third circular plate 2121 that deviates from the second push rod 2119 just slides and fits on the first push rod 2118, and the first spur gear 2114 continues to rotate 90°, so that the first spur gear 2114 drives the second rotating rod 2111, the first circular plate 2113 and the first push rod 2118 to continue to rotate 90° clockwise. At the same time, the first spur gear 2114 drives the meshing second spur gear 2116 to continue to rotate 90° counterclockwise, so that the second spur gear 2116 drives the third rotating rod 2115, the second circular plate 2117 and the second push rod 2119 to rotate 90° counterclockwise. The rotating rod 2107 pushes the U-shaped groove 2123, driving the third circular plate 2121 to rotate 90° counterclockwise to complete the reset, and then the push-pull rod 2124 is driven to move downward through the third circular plate 2121. The push-pull rod 2124 is pulled to drive the arc plate 207 to move downward along the slide groove 205, so that the second through hole 208 on the arc plate 207 gradually completely overlaps with the first through hole 206 and then completely staggers, so that the sodium molybdate solution in the centrifugal cylinder 204 gradually cannot be thrown out from the first through hole 206, and the first spur gear 2114 continues to rotate 180° clockwise. During this process, the first stop rod 2118 The second push rod 2119 will not interfere with the U-shaped groove 2123. The first push rod 2118 and the second push rod 2119 will idle 180° on the side away from the third circular plate 2121. Therefore, the rotation in this process will not drive the third circular plate 2121 to rotate, so that the arc plate 207 is in a stationary state, and the second through hole 208 on the arc plate 207 is in a staggered state with the first through hole 206. At this time, the arc plate 207 completely blocks the first through hole 206. Therefore, in this state, the sodium molybdate solution in the centrifugal cylinder 204 will not be thrown out. In summary, the process of the first spur gear 2114 rotating one circle can be The process is divided into three steps of 0-90°, 90-180° and 180-360°. The process of 0-180° is integrated into one step, that is, sodium molybdate can be thrown out of the first through hole 206 by the centrifugal cylinder 204. In the process of 180-360°, the first through hole 206 and the second through hole 208 are completely staggered, so that sodium molybdate cannot be thrown out of the first through hole 206 by the centrifugal cylinder 204 (that is, it is prevented that the sodium molybdate solution is centrifugally thrown out to the outside of the centrifugal cylinder 204 during this process), so that the sodium molybdate solution is intermittently thrown out of the centrifugal cylinder 204, which paves the way for the subsequent formation of a liquid film and crystallization of the sodium molybdate solution after being thrown out.

[0046] The operation process of this embodiment is as follows: during the rotation of the centrifugal drum 204, the sodium molybdate solution in the centrifugal drum 204 is thrown onto the fabric 3105 in the liquid film assembly 31 (how to throw out the sodium molybdate solution has been described in detail in the operation process of the first embodiment), so that the thrown sodium molybdate solution forms a liquid film on the fabric 3105, and the sodium molybdate solution on the fabric 3105 is heated by heat radiation in conjunction with the use of the heating plate in the liquid film assembly 31, thereby accelerating the crystallization of the sodium molybdate, so that the crystallized sodium molybdate adheres to the fabric 3105, and the sodium molybdate After the sodium solution crystallizes, the electric telescopic rod 3221 is started, and the electric telescopic rod 3221 drives the push rod 3222 to move into the sleeve 3210, so that the push rod 3222 hits the locking rod 3217, and the locking rod 3217 moves into the second insertion hole 3216 in the cylindrical tube 3212, so that the sleeve 3210 and the cylindrical tube 3212 can rotate synchronously. In the process of the first motor 201 driving the first rotating shaft 202 to rotate, the worm 209 is also driven to rotate, and then the meshing worm wheel 3204 is driven to rotate. In the process of the worm wheel 3204 rotating, the belt The first transmission rod 3203 and the third bevel gear 3205 are driven to rotate, the third bevel gear 3205 drives the meshed fourth bevel gear 3207 to rotate, and the second transmission rod 3206 and the first sprocket 3208 are driven to rotate through the fourth bevel gear 3207, and the first sprocket 3208 drives the second sprocket 3213 to rotate through the chain, so that the second sprocket 3213 drives the cylindrical tube 3212, the sleeve 3210 and the winding roller 3211 to rotate, so that the winding roller 3211 winds up the traction rope 3214, and the traction force of the traction rope 3214 drives the arc support The rack plate 3104 moves toward the first collecting box 3106, so that the arc-shaped bracket plate 3104 pulls and drives the fabric 3105 to stick to the first collecting box 3106. As the fabric 3105 moves, the sodium molybdate crystals on the fabric 3105 are scraped off by the first collecting box 3106 and collected inside it. In summary, the sodium molybdate solution is thrown out to form a large-scale liquid film on the fabric 3105. After the liquid film is formed, it can be quickly crystallized by heating, and then it is scraped off and collected in a concentrated manner, so that the rate of separation and crystallization of sodium molybdate is faster, thereby improving the separation and crystallization efficiency of sodium molybdate.

[0047] Example 4, please refer to Figure 1-18The fourth embodiment is improved on the basis of the first embodiment as follows: the guide assembly 33 includes a sleeve 3301 symmetrically fixedly connected to the top of the base 1, a guide rod 3302 is slidably inserted inside the sleeve 3301, a conical plate 3303 is fixedly connected between the two guide rods 3302, a partition plate 3304 is symmetrically fixedly connected to the top of the conical plate 3303, an annular plate 3305 is slidably connected to the inner side of the conical plate 3303, and the annular plate 3305 and the arc plate 207 are fixedly connected.

[0048] The operation process of this embodiment is as follows: during the rotation of the centrifugal cylinder 204, the arc plate 207 is driven to rotate together with the centrifugal cylinder 204, so that the arc plate 207 further drives the annular plate 3305 to rotate. At the same time, the push-pull rod 2124 is reciprocated to lift and pull down, driving the arc plate 207 to move up and down reciprocatingly, so that the arc plate 207 drives the annular plate 3305 and the conical plate 3303 to move up and down. During the up and down movement of the conical plate 3303, the sodium molybdate crystals on the fabric 3105 are continuously scraped, so that a part of the sodium molybdate crystals on the fabric 3105 fall off and are collected in the second collecting box 3 109, the arrangement of the conical plate 3303 and the partition 3304 ensures that after the sodium molybdate solution is thrown out, a small amount of the sodium molybdate solution drips on the conical plate 3303, and this part of the sodium molybdate solution flows along the surface of the conical plate 3303 to the fabric 3105. At the same time, the blocking effect of the partition 3304 can prevent the sodium molybdate solution from deviating from the direction of the fabric 3105 during the process of flowing on the conical plate 3303, thereby avoiding that part of the sodium molybdate solution dripping on the conical plate 3303 cannot flow to the fabric 3105, causing waste, and ultimately affecting the total amount of sodium molybdate after crystallization.
