Description

Technical Field

[0001] The invention relates to ammonium molybdate crystal stirring equipment, in particular to an ammonium molybdate crystal stirring auxiliary device. Background Art

[0002] The stirring auxiliary device of ammonium molybdate crystallization can promote the uniformity of crystallization during the crystallization process. Stirring can ensure that the temperature, concentration and reactant distribution during the crystallization process are more uniform, thereby avoiding the phenomenon of uneven crystallization caused by local oversaturation or over-diluted. Uniform stirring helps to form crystals of uniform size and regular shape, improving the quality of the product.

[0003] The existing stirring auxiliary devices for ammonium molybdate crystallization are mainly downward-rotating spiral stirring paddles, stirring shafts, and frame-type stirring paddles. During use, there are problems such as insufficient solution stirring and long reaction time, resulting in uneven crystal form, low efficiency, affecting product quality, inconvenient disassembly for maintenance, long maintenance time, and low production efficiency.

[0004] Chinese patent publication number CN203417612U discloses an agitator, which is mainly composed of a stirring shaft made of a stainless steel tube, a coupling, a fixed shaft sleeve, a downward spiral stirring blade, an elliptical frame stirring, and an upward spiral stirring blade. The agitator is conducive to the formation of crystal particles of solution crystals, and the crystal particles are evenly distributed, the output is significantly improved, and the structure is simple, maintenance is convenient, the stirring capacity is sufficient, the production efficiency is effectively improved, and the occurrence rate of equipment failure is greatly reduced. It is particularly suitable for the production process of ammonium heptamolybdate chemical reagents. The above-mentioned agitator still has the following defects when used for mixing: when the agitator is stirring the ammonium molybdate crystallization process, it is necessary to realize high-speed rotation through the stirring shaft and the stirring blades, so as to realize contact with the ammonium molybdate crystal raw material to form a stirring and mixing operation. As the ammonium molybdate continues to crystallize, the amount of crystals increases, and the stirring blades will still impact the crystals at a high speed and over a large area, which can easily cause a large number of ammonium molybdate crystals to be broken after impact. Because it is difficult to know the amount of crystals in time to reduce the speed and store the stirring blades, it is difficult to avoid a large number of ammonium molybdate crystals from being broken after impact, resulting in a significant reduction in the quality of the ammonium molybdate crystals.

[0013] The beneficial effects of the present invention are:

[0014] 1. A synchronous protection mechanism and a protection storage mechanism are adopted. The reduction motor drives the rotating frame to rotate clockwise. The rotating frame carries the sliding rod to move upward, and the sliding rod drives the bearing ring to move upward. The two limit rings carry the linkage rod to move upward, and the linkage rod drives the connecting block to move upward along the inner wall of the mixing slide. The two hinged shafts respectively carry the top ends of the two linkage sleeve rods to move upward, and the sleeve bar approaches the center point of the mixing slide. The sleeve bar drives the linkage block to approach the center point of the mixing slide. The two stirring blades enter the two protective baffles at the same time. The silicone pads on the protective baffles are arc-shaped and contact a large amount of ammonium molybdate crystals at a low speed. The amount of crystallization is known in time through the photosensitive sensor, so as to accurately protect the speed reduction achieved by the component and store the two stirring blades, so as to avoid the two stirring blades contacting the ammonium molybdate crystals at a high speed, resulting in a large amount of ammonium molybdate crystals being broken after impact, thereby greatly improving the quality of ammonium molybdate crystals.

[0015] 2. Through the crystallization detection mechanism, the rotating motor drives the rotating block to rotate counterclockwise and then clockwise. The L-shaped rotating plate can drive the support block to make the protective ring reciprocate. The L-shaped rotating plate itself can also drive the detection lamp beads to rotate reciprocatingly, so as to conduct a large-scale detection of the crystallization condition. When the ammonium molybdate crystal neutralization liquid begins to become turbid, the light intensity value sensed by the photosensitive sensor to the detection lamp beads decreases. When the light intensity sensed by the photosensitive sensor is lower than the protection light intensity value set by the controller, it is known that a large number of crystallization operations are started at this time. The synchronous protection mechanism and the protection storage mechanism realize immediate deceleration and storage of the two stirring blades to avoid high-speed contact with a large number of ammonium molybdate crystals, causing the ammonium molybdate crystals to break, thereby greatly improving the quality of ammonium molybdate crystals.

[0016] 3. Adopt precise protection components, start the rotating motor through the controller, the rotating rod carries the driving gear to rotate, and the speed sensor can sense the speed of the rotating rod. In the initial stage, the protective baffle and the stirring blade can rotate at a high speed to stir and mix the ammonium molybdate crystal neutralization liquid over a large area. When a large amount of crystals are formed, the two protective baffles are immediately slowed down to stir and mix, so as to avoid a large amount of ammonium molybdate crystals from being impacted and broken, thereby greatly improving the quality of ammonium molybdate crystals.

[0017] According to the mutual influence of the above multiple functions, first, the L-shaped rotating plate drives the detection lamp beads to rotate back and forth, and performs large-scale detection of the crystallization status. In summary, the amount of crystallization can be known in time. When a large amount of crystallization occurs, the two stirring blades are respectively stored in the two protective baffles at the same time, and the two protective baffles and the silicone pad are slowed down and stirred and mixed. In this way, the speed is reduced and the two stirring blades are stored, so as to avoid a large number of ammonium molybdate crystals from being impacted and broken, and the quality of ammonium molybdate crystals is greatly improved.

[0037] A rotating rod 41 is fixedly mounted on the inner wall of the driving gear 40, and a rotating motor 42 is coaxially connected to the bottom end of the rotating rod 41, and the rotating motor 42 is fixedly mounted between the sleeve concave plate 2, and a speed sensor 43 is fixedly mounted on the top of the rotating rod 41; a reinforcing plate 44 is provided on the top of the speed sensor 43, and the sleeve concave plate 2 and the speed sensor 43 are both fixedly connected to the reinforcing plate 44. The lower surface of the driving gear 40 is rotationally connected to the sleeve concave plate 2, and the upper surface of the driven gear 39 and the upper surface of the driving gear 40 are in the same horizontal plane.

[0038] The working principle of the present invention is as follows:

[0039] Step 1, during crystallization stirring, add ammonium molybdate crystallization neutralizing liquid into the feed hopper 45 and let it enter the stirring tank 1. When the depth of the ammonium molybdate crystallization neutralizing liquid is three quarters of the depth inside the stirring tank 1, start the rotating motor 42 through the controller 18. The rotating motor 42 drives the rotating rod 41 to rotate, and the rotating rod 41 carries the driving gear 40 to rotate. At the same time, the concave plate 2 is supported by the reinforcing plate 44, and the reinforcing plate 44 supports the speed sensor 43. The speed sensor 43 can realize speed sensing of the rotating rod 41. When the sensing speed of the rotating rod 41 is high-speed rotation, the rotating rod 41 carries the driving gear 40 to rotate, and the driving gear 40 drives the driven gear 39 to rotate, and the driven gear 39 carries the stirring slide 9 to rotate.

[0040] The mixing slide 9 drives the connecting block 10 to rotate, the connecting block 10 drives the linkage rod 8 to rotate, the linkage rod 8 drives the two limit rings 7 to rotate, the two limit rings 7 rotate on the bearing ring 6, and the linkage rod 8 can rotate synchronously inside the bearing ring 6, so that the mixing slide 9 drives the turntable 24 to rotate at the same time, the turntable 24 carries the rotating ring 25 to rotate the protective baffle 17, and the protective baffle 17 makes the mixing blades 16 inside the storage tank 21 rotate synchronously, and the turntable 24 carries the two sliding rods 23 to rotate, and the sliding rods 23 drive the sleeve strip 14 to rotate The sleeve bar 14 carries the linkage block 15 to rotate, so that the linkage block 15 carries the stirring blade 16 to rotate, and the stirring blade 16 and the protective baffle 17 can stir and mix the ammonium molybdate crystal neutralization liquid inside the stirring tank 1. At the same time, the resistance heating plate 26 at the bottom of the stirring tank 1 realizes the heating operation. In the initial stage, the protective baffle 17 and the stirring blade 16 can rotate at a high speed to stir and mix the ammonium molybdate crystal neutralization liquid over a large area, wherein the high-speed frequency is set to one hundred and twenty revolutions per minute, which can allow the ammonium molybdate crystal neutralization liquid to achieve rapid crystallization.

[0041] Step 2, during crystallization detection, the rotating motor 28 is supported by the support block 29, and the controller 18 starts the rotating motor 28. The rotating motor 28 drives the rotating block 27 to rotate counterclockwise and then clockwise. The rotating block 27 carries the L-shaped rotating plate 30 to rotate back and forth. The L-shaped rotating plate 30 drives the support block 31 to make the protective ring 33 rotate back and forth. The support block 31 also drives the photosensitive sensor 32 to rotate back and forth. The L-shaped rotating plate 30 drives the detection lamp bead 34 to rotate back and forth. After the detection lamp bead 34 is turned on, it provides light intensity. When the ammonium molybdate crystallization neutralization solution begins to become turbid, the light intensity value sensed by the photosensitive sensor 32 to the detection lamp bead 34 decreases. When the light intensity sensed by the photosensitive sensor 32 is lower than the protective light intensity value set by the controller 18, it is known that a large amount of crystallization operation has begun at this time, and the protective operation can be performed immediately.

[0042] Step 3: During precise protection, the controller 18 is used to start the rotating motor 42, which drives the rotating rod 41 to decelerate, and the rotating rod 41 carries the driving gear 40 to decelerate, the driving gear 40 carries the driven gear 39 to decelerate, the driven gear 39 carries the stirring roller 9 to decelerate, the stirring roller 9 carries the connecting block 10 to decelerate, and at the same time, the stirring roller 9 drives the turntable 24 to rotate the rotating ring 25, and the rotating ring 25 carries the protective baffle 17 and the stirring blade 16 inside the storage tank 21 to achieve decelerated stirring. The reinforcing plate 44 is supported by the sleeve concave plate 2, and the reinforcing plate 44 supports the speed sensor 43. The speed sensor 43 senses the speed of the rotating rod 41. When the speed sensor 43 senses a low speed, the controller 18 keeps the rotating motor 42 driven at the specified low speed. At the same time, the controller 18 starts the reduction motor 3 to drive.

[0043] Step 4: During synchronous protection, the reduction motor 3 drives the rotating frame 4 to rotate clockwise, and the rotating frame 4 carries the slide bar 5 to move upward, and the slide bar 5 carries the two limit support rings 20 to move upward. The two limit support rings 20 slide upward along the rotating frame 4, and the slide bar 5 drives the bearing ring 6 to move upward. The bearing ring 6 carries the two limit rings 7 to move upward, and the two limit rings 7 carry the linkage rod 8 to move upward. The linkage rod 8 slides along the inner wall of the mixing slide 9. At the same time, the linkage rod 8 drives the connecting block 10 to move upward along the inner wall of the mixing slide 9, and the connecting block 10 drives the two hinged shafts 11 to move upward. The two hinged shafts 11 respectively carry the top parts of the two linkage sleeves 12 to move upward, and the linkage sleeve 12 carries the connecting shaft 13 to approach the center point of the mixing slide 9.

[0044] Step 5. During protective storage, the connecting shaft 13 carries the sleeve strip 14 to approach the center point of the stirring slide 9, and the sleeve strip 14 slides along the inner wall of the turntable 24 and the outer wall of the sliding rod 23. In this way, the sleeve strip 14 drives the linkage block 15 to approach the center point of the stirring slide 9, and the linkage block 15 carries the stirring blade 16 to approach the center point of the stirring slide 9. The stirring blade 16 can enter the storage groove 21 for storage, so that the protective baffle 17 can store all the stirring blades 16.

[0045] When the slide bar 5 moves upward, it will carry the slider 35 upward, and the slider 35 moves upward along the inner wall of the guide frame 36, and the support plate 38 is supported by the reduction motor 3, and the support plate 38 supports the guide frame 36, and the guide frame 36 realizes the support operation of the distance sensor 37. The distance sensor 37 can realize distance sensing of the upper surface of the slider 35. When the distance sensed by the distance sensor 37 is the same as the upward distance set by the controller 18, the two stirring blades 16 enter the inside of the two protective baffles 17 respectively and simultaneously, and complete the operation of accommodating the two stirring blades 16, so that the two protective baffles 17 can rotate at a low speed. The silicone pad 22 on the protective baffle 17 is arc-shaped, and the silicone pad 22 contacts a large amount of ammonium molybdate crystals, and quickly separates from the side guide to avoid direct hard impact causing a large amount of ammonium molybdate crystals to break, and can realize safe protection stirring at a low speed, greatly improving the quality of ammonium molybdate crystals. After the crystallization is completed, the lower row valve 19 is opened to realize the lower row of ammonium molybdate crystals.
