Description

Technical Field

[0001] The invention relates to the field of ammonium tetramolybdate production, and in particular to a vibration device for preventing α-type ammonium tetramolybdate from hardening. Background Art

[0002] During the storage process, when the room temperature exceeds a certain value or the storage time is too long, α-ammonium tetramolybdate products will become hardened, which will cause many inconveniences to the subsequent deep processing. Therefore, during the storage process, it is necessary not only to control the room temperature, but also to use a vibration platform to vibrate the product regularly for 1-2 minutes to prevent α-ammonium tetramolybdate from hardening.

[0003] Since α-ammonium tetramolybdate is generally packed in ton bags and stacked in the warehouse, each time the vibration platform is used to vibrate the product for 1-2 minutes, it is necessary to use a mobile crane or forklift and other equipment to lift the ton bag and place it on the vibration platform. After the vibration is completed, the ton bag is lifted away and restored to the stack. It can be seen that each time the vibration platform is used to vibrate the product, the ton bag needs to be repeatedly moved, which is time-consuming and labor-intensive, slow in operation speed and low in efficiency.

[0004] In addition, the commonly used vibration platform relies on a vibration motor to drive a hard vibration plate to vibrate. The ton bag is placed as a whole on the vibration plate to receive vibration. The ton bag vibrates as a whole. The products inside the ton bag, especially the products at the bottom of the ton bag, are further squeezed and compacted by the vibration of the products in the middle and upper parts of the ton bag. As a result, the products at the bottom of the ton bag are not as effective in preventing the hardening of α-ammonium tetramolybdate as those in the middle and upper parts of the ton bag. The α-ammonium tetramolybdate at the bottom of the ton bag is still prone to hardening. Summary of the invention

[0022] The present invention proposes a vibration device for preventing α-type ammonium tetramolybdate from being compacted. The vibration device for preventing α-type ammonium tetramolybdate from being compacted supports a ton bag 14 through a net bag 3, and then drives a vibration plate 10 to push up the bottom of the ton bag 14 for vibration with the help of a translation device 4 and a lifting device 6, so as to crush the α-type ammonium tetramolybdate compacted at the bottom of the ton bag 14. At the same time, after the vibration plate 10 pushes up the bottom of the ton bag 14, the vibration plate 10 is located in the middle of the ton bag 14 and is relatively close to the α-type ammonium tetramolybdate at the top of the ton bag 14. The vibration generated by the vibration plate 10 can be transmitted to the α-type ammonium tetramolybdate at various parts of the ton bag 14, and the α-type ammonium tetramolybdate at various parts of the ton bag 14 is fully vibrated, so as to effectively prevent the α-type ammonium tetramolybdate from being compacted, and the effect of preventing the α-type ammonium tetramolybdate from being compacted is good.

[0023] Specifically, in one embodiment of the invention, Figure 1 As shown, the vibration device for preventing α-type ammonium tetramolybdate from hardening includes an AGV trolley 1 and a rail lifting device 15. The rail lifting device 15 includes at least a hanging rail and a driving mechanism installed on the hanging rail. The hanging rail is fixedly installed on the indoor ceiling. The conventional driving mechanism is the AGV trolley 1. An electric hoist 38 is arranged on the rail lifting device 15. The electric hoist 38 is driven by the AGV trolley 1 to move horizontally along the hanging rail to directly above each ton bag 14.

[0024] In this embodiment, if Figure 1 , Figure 4-Figure 6As shown, a plurality of columns 2 are arranged at the upper end of the AGV trolley 1, a net bag 3 is installed at the upper end of the plurality of columns 2, a translation device 4 fixedly connected to the AGV trolley 1 is arranged directly below the net bag 3, a lifting device 6 is arranged on the translation device 4, and the lifting device 6 is driven to move horizontally by the translation device 4. Specifically, a mounting plate 5 is arranged on the translation device 4, and the lifting device 6 is fixedly installed on the mounting plate 5. This design facilitates the connection of a plurality of lifting devices 6 with the translation device 4, a vibration plate 10 is arranged on the upper end of the lifting device 6, and the vibration plate 10 is driven to move up and down by the lifting device 6 Specifically, a mounting plate 27 is provided at the upper end of the lifting device 6, a spring 9 is installed on the mounting plate 27, and a vibration plate 10 is installed on the upper end of the spring 9. The setting of the mounting plate 27 is convenient for arranging multiple springs 9. The lifting device 6 and the vibration plate 10 are connected by the spring 9 to avoid the vibration of the vibration plate 10 from being transmitted to the lifting device 6, thereby protecting the safety of the lifting device 6; further, shock-absorbing seats 8 are provided at the upper and lower ends of the spring 9, and the spring 9 is fixedly connected to the vibration plate 10 and the mounting plate 27 through the shock-absorbing seat 8. This design facilitates the connection of the spring 9 with the vibration plate 10 and the mounting plate 27. The vibration plate 10 is provided with a vibration motor 12, which drives the vibration plate 10 to vibrate. The vibration motor 12 is located at the lower end of the vibration plate 10. The upper surface of the vibration plate 10 is provided with a protrusion 11. The setting of the protrusion 11 can enhance the vibration effect on the α-ammonium tetramolybdate at the bottom of the ton bag 14, and fully crush the α-ammonium tetramolybdate that has formed a plate.

[0025] In this embodiment, the ton bags 14 are not placed in a stacked manner, but only one layer of ton bags 14 is placed on the ground, and then the rail lifting device 15 is arranged directly above the ton bags 14, and the electric hoist 38 is installed on the rail lifting device 15. The electric hoist 38 can move on the rail lifting device 15 to the top of each ton bag 14, and then the ton bag 14 is lifted by the electric hoist 38. After the ton bag 14 is lifted, the AGV trolley 1 moves to the bottom of the ton bag 14, and then the electric hoist 38 drives the ton bag 14 to be lowered, and the ton bag 14 is placed by supporting the net bag 3, such as Figure 6 As shown, the lifting device 6 is then controlled to lift the vibration plate 10, and the vibration motor 12 is turned on. The vibration plate 10 is pushed against the bottom of the ton bag 14 to vibrate the α-type ammonium tetramolybdate, and the α-type ammonium tetramolybdate that is compacted at the bottom of the ton bag 14 is crushed. After a period of time, the lifting device 6 drives the vibration plate 10 to descend and reset, and then the translation device 4 drives the vibration plate 10 to move one position, and the above actions are repeated. The lifting device 6 lifts the vibration plate 10 again to push against the bottom of the ton bag 14 to vibrate the α-type ammonium tetramolybdate. Because the bottom surface area of ​​the ton bag 14 is large, the upper surface area of ​​the vibration plate 10 is small. Figure 5As shown, after the vibration plate 10 has completed the lifting and vibration of one part of the lower surface of the ton bag 14, it is necessary to drive the vibration plate 10 to move one position through the translation device 4, and then repeat the above-mentioned action to lift and vibrate another part of the lower surface of the ton bag 14. This can be repeated for multiple times to complete the lifting and vibration of the entire area of ​​the lower surface of the ton bag 14. The reason why the upper surface area of ​​the vibration plate 10 is designed to be small is that the lower surface area of ​​the ton bag 14 is too large, and considering the bearing capacity of the translation device 4 and the spring 9, the installation area of ​​the mounting plate 5 and other factors, the upper surface area of ​​the vibration plate 10 cannot be designed to be very large. Secondly, it is to lift multiple positions of the lower surface of the ton bag 14 multiple times to make the α-ammonium tetramolybdate in the ton bag 14 fully flow and be fully vibrated to prevent the α-ammonium tetramolybdate from hardening.

[0026] In the present embodiment, after the vibration plate 10 is pushed onto the bottom of the ton bag 14, the α-ammonium tetramolybdate at the rising path of the vibration plate 10 in the ton bag 14 flows toward the edges around the ton bag 14, and the vibration plate 10 rises to the middle of the ton bag 14, and is closer to the α-ammonium tetramolybdate at the top of the ton bag 14. With this design, the vibration generated by the vibration plate 10 can be transmitted to the α-ammonium tetramolybdate in various parts of the ton bag 14, including the α-ammonium tetramolybdate at the top of the ton bag 14, and the α-ammonium tetramolybdate in various parts of the ton bag 14 is fully vibrated, thereby effectively preventing the α-ammonium tetramolybdate from being hardened, and the effect of preventing the α-ammonium tetramolybdate from being hardened is good.

[0027] In this embodiment, after the vibration plate 10 is pushed onto the bottom of the ton bag 14, the area of ​​the bottom of the ton bag 14 away from the vibration plate 10 still remains tightly pressed against the net bag 3, that is, although the vibration plate 10 is pushed onto the ton bag 14, the ton bag 14 still needs to rely on the net bag 3 for support.

[0028] In this embodiment, after a ton bag 14 is vibrated, the electric hoist 38 is controlled to lift the ton bag 14, and then the AGV trolley 1 under the ton bag 14 is moved away, and finally the ton bag 14 is put down.

[0029] In this embodiment, if Figure 1 As shown, by setting a designated placement position for each ton bag 14, the AGV trolley 1 automatically moves to the bottom of the target ton bag 14 to receive the ton bag 14 after the ton bag 14 is lifted; in addition, multiple electric hoists 38 are controlled to move to the top of each ton bag 14 on the rail lifting device 15, and multiple AGV trolleys 1 are automatically moved to the bottom of a ton bag 14 alternately, so that the ton bag 14 is automatically lifted and vibrated in an assembly line to prevent the α-ammonium tetramolybdate from hardening, and the vibration operation speed is fast and the efficiency is high; specifically, as Figure 1As shown, after the electric hoist 38 on the left moves to the top of the ton bag 14, the electric hoist 38 is controlled to descend and lift the ton bag 14, and then the AGV trolley 1 automatically moves to the bottom of the ton bag 14 to receive the ton bag 14, and then the electric hoist 38 is controlled to lower the ton bag 14 to the net bag 3, and the translation device 4, the lifting device 6 and the vibration motor 12 are started to vibrate and crush the α-ammonium tetramolybdate that has been plated on the ton bag 14, and prevent the α-ammonium tetramolybdate from being plated. At the same time, the electric hoist 38 also moves along Figure 1 The electric hoist 38 moves in the direction indicated by the middle arrow to the top of the next ton bag 14, repeats the above-mentioned action, lifts the ton bag 14, and moves another AGV trolley 1 to the bottom of the ton bag 14 to receive the ton bag 14, and then vibrates the ton bag 14 to crush the α-type ammonium tetramolybdate that has been plated, and prevents the α-type ammonium tetramolybdate from being plated. As for the electric hoist 38, it continues to move along the Figure 1 Move in the direction indicated by the middle arrow to the top of the next ton bag 14, repeat the above actions, lift the ton bag 14, and wait for the arrival of the AGV 1. Figure 1 After the ton bag 14 on the right side of the middle is vibrated, it is lifted by another electric hoist 38, and the AGV trolley 1 under the ton bag 14 leaves and goes to Figure 1 The ton bag 14 that has been lifted and is to be vibrated on the left side of the middle is received below the ton bag 14. Figure 1 The ton bag 14 on the middle right that has been vibrated is lowered to the ground by another electric hoist 38. Therefore, in order to realize the automatic lifting of the ton bag 14 in an assembly line manner for vibration to prevent the compaction of α-ammonium tetramolybdate, with fast vibration operation speed and high efficiency, at least two electric hoists 38 and two AGV carts 1 are required, wherein one electric hoist 38 is used to lift the ton bag 14 to be vibrated and place it on the AGV cart 1, and the other electric hoist 38 is used to lift the ton bag 14 that has been vibrated and place it on the ground.

[0030] In this embodiment, the ton bag 14 has a lifting rope 13. If the electric hoist 38 can hook the lifting rope 13 by itself, no manual assistance is required, thereby realizing an unmanned assembly line-style fully automatic lifting of the ton bag 14 for vibration to prevent the α-type ammonium tetramolybdate from compacting and automatically lifting and placing it on the ground after the vibration is completed. The vibration operation is faster, more efficient, and has lower labor costs. It is only necessary to set a control program for the rail lifting device 15, the electric hoist 38, the AGV trolley 1 and the translation device 4, the lifting device 6 and the vibration motor 12 thereon to run automatically.

[0031] In this embodiment, further, the vibration device for preventing the α-ammonium tetramolybdate from hardening further includes a filtering mechanism for filtering the α-ammonium tetramolybdate in the ton bag 14 after the vibration of the vibration plate 10, filtering out the uncrushed hardened blocks and crushing them, thereby ensuring the vibration effect of the vibration device and effectively preventing the α-ammonium tetramolybdate from hardening. Figure 1-Figure 3As shown, the filtering mechanism is suspended on a rail lifting device 15, and the rail lifting device 15 drives the filtering mechanism to move horizontally to the top of each ton bag 14, and then the α-ammonium tetramolybdate in the ton bag 14 is filtered to filter out the compacted α-ammonium tetramolybdate and crush it.

[0032] Specifically, in this embodiment, Figure 1-Figure 3 As shown, the filtering mechanism at least includes: a mounting frame 16, a guide tube 23, an annular filter screen 32, and a crushing ring 37. The structure of the crushing ring 37 is as shown in Figure 7 As shown, the upper end of the mounting frame 16 is connected to the track lifting device 15, and the track lifting device 15 drives the mounting frame 16 along the Figure 1 It should be noted that the driving mechanism of the rail hoisting device 15 usually has a braking function, so the mounting frame 16 and the electric hoist 38 move horizontally in the direction indicated by the middle arrow. Figure 1 After being moved horizontally in the direction indicated by the middle arrow, it can be fixed and not continue to move horizontally, ensuring the safety of lifting.

[0033] In this embodiment, if Figure 1-Figure 3 As shown, a lifting device 21 is installed on the mounting frame 16, and a mounting frame 22 is arranged on the lifting device 21. The mounting frame 22 is lifted and lowered by the lifting device 21. The guide tube 23 is fixedly connected to the mounting frame 22. The upper end of the guide tube 23 is sealed and the lower end is open. A connecting rod 30 is fixedly installed on the top of the guide tube 23. A suction tube 31 is fixedly connected to the lower end of the connecting rod 30. The lower end of the suction tube 31 extends out of the guide tube 23. A spiral shaft 29 is arranged in the suction tube 31. A lifting motor 28 is arranged on the upper end of the guide tube 23. The upper end of the spiral shaft 29 is transmission-connected to the lifting motor 28. Figure 1 As shown, the lifting device 21 drives the suction cylinder 31 to descend so that the lower end of the suction cylinder 31 is inserted into the ton bag 14, and then the lifting motor 28 is started to drive the screw shaft 29 to rotate to send the α-type ammonium tetramolybdate directly below the suction cylinder 31 into the suction cylinder 31 and rise along the suction cylinder 31. At the same time, the lower end of the suction cylinder 31 continues to descend in the ton bag 14 until the lower end of the suction cylinder 31 approaches the bottom of the ton bag 14. After the lower end of the suction cylinder 31 approaches the bottom of the ton bag 14, the lifting device 21 stops moving, and the lifting motor 28 is stopped. The screw shaft 29 is continuously driven to rotate, and the α-ammonium tetramolybdate in the ton bag 14 is gradually fed into the suction cylinder 31. At the same time, the α-ammonium tetramolybdate in the suction cylinder 31 overflows from the upper end of the suction cylinder 31 and falls into the annular filter 32. The α-ammonium tetramolybdate is filtered by the annular filter 32 and falls into the ton bag 14. The compacted α-ammonium tetramolybdate remains on the annular filter 32 until all the α-ammonium tetramolybdate in the ton bag 14 enters the suction cylinder 31 and is filtered once, and the lifting motor 28 is controlled to stop. The overall flow direction of the α-ammonium tetramolybdate is as follows: Figure 1 Indicated by the arrow.

[0034] In this embodiment, if Figure 1-Figure 3 As shown, the annular filter screen 32 is tightly sleeved on the outside of the suction cylinder 31 and is sealed and connected to the inner wall of the guide cylinder 23; the crushing ring 37 is slidably installed in the guide cylinder 23 and is located above the annular filter screen 32. The lifting motor 28 is provided with a brake motor 36, and the output shaft of the brake motor 36 is installed with a rope winding roller, and a traction rope 34 is wound on the rope winding roller. The lower end of the traction rope 34 passes through the fixed pulley 35 and the threading hole 33 and then enters the guide cylinder 23 to connect with the crushing ring 37. The fixed pulley 35 is installed on the lifting motor 28. The guide cylinder 23 and the suction cylinder 31 are coaxial and vertically arranged. After all the α-ammonium tetramolybdate in the ton bag 14 enters the suction barrel 31 and is filtered once, the lifting motor 28 is controlled to stop the action, and then the lifting device 21 is controlled to drive the suction barrel 31 to rise, and then the lifting motor 28 is controlled to drive the screw shaft 29 to reverse, so that the α-ammonium tetramolybdate in the suction barrel 31 flows out from the lower end of the suction barrel 31 and returns to the ton bag 14. At the same time, the brake motor 36 is controlled to rotate and unfold the traction rope 34 to release the crushing ring 37. The crushing ring 37 descends and collides with the annular filter screen 32 to crush the plate lumps filtered by the annular filter screen 32. The crushed α-ammonium tetramolybdate falls into the ton bag 14, and finally the brake motor 36 is controlled to rotate and retract the traction rope 34 to drive the crushing ring 37 to reset. After the suction barrel 31 rises and leaves the ton bag 14, the rail lifting device 15 can drive the filtering mechanism to move horizontally to the left to just above another ton bag 14 to continue the filtering operation of the α-ammonium tetramolybdate in the ton bag 14. Figure 1 As shown, the filtered ton bag 14 is lifted by the electric hoist 38 on the right side of the filtering mechanism and placed on the ground. Therefore, the filtering mechanism should be provided with electric hoists 38 in front and rear of the moving direction on the rail lifting device 15, and the AGV trolley 1 should have at least two of them.

[0035] In this embodiment, further, the filtering mechanism also includes: a plurality of mounting cylinders 24 and a vibration motor 27, such as Figure 1-Figure 3As shown, a plurality of mounting tubes 24 are evenly distributed on the outer wall of the guide tube 23, and a vibration rod 25 is tightly inserted on each mounting tube 24. The vibration rod 25 is vertically arranged, and the lower ends of all the vibration rods 25 extend to the lower end of the suction tube 31. The upper ends of all the vibration rods 25 are commonly connected to a vibration plate 26. The vibration motor 27 is installed on the vibration plate 26. After the vibration motor 27 is started, all the vibration rods 25 are driven to vibrate through the vibration plate 26. When the lower end of the suction tube 31 extends to the bottom of the ton bag 14, the lower end of the vibration rod 25 also extends to the bottom of the ton bag 14 to contact the suction tube 31 in the ton bag 14. 1 is vibrated, which, on the one hand, crushes the compacted α-type ammonium tetramolybdate, and on the other hand, accelerates the flow of the α-type ammonium tetramolybdate, so that the α-type ammonium tetramolybdate flows smoothly and quickly to the lower end of the suction cylinder 31 and is sucked away by the suction cylinder 31; in addition, the vibration of the vibration rod 25 drives the mounting cylinder 24 and the guide cylinder 23 to vibrate, and the vibration of the guide cylinder 23 drives the annular filter 32 to vibrate, thereby accelerating the speed of the α-type ammonium tetramolybdate passing through the annular filter 32, preventing the α-type ammonium tetramolybdate overflowing from the suction cylinder 31 in the guide cylinder 23 from accumulating on the annular filter 32 and affecting the flow of the α-type ammonium tetramolybdate, which helps to improve the filtration efficiency.

[0036] In this embodiment, if Figure 3 As shown, the mounting frame 16 is in an inverted L shape, and a balancing track 19 is arranged next to the track lifting device 15. The balancing track 19 is parallel to the track lifting device 15. The mounting frame 16 is in rolling contact with the balancing track 19 through the ball 20. With this design, the balancing track 19 can be used to keep the mounting frame 16 balanced and move stably to avoid the problem of tilting of the suction barrel 31. In addition, a conductive rod 18 is arranged on the balancing track 19, and a pantograph 17 is arranged on the mounting frame 16. The pantograph 17 is slidably connected with the conductive rod 18 to draw electricity.

[0037] It should be noted that the translation device 4, lifting device one 6 and lifting device two 21 of this embodiment all belong to the existing technology, such as common linear motors, cylinders or hydraulic cylinders and other devices that can drive objects to move in a straight line. Therefore, this article will not go into details about the specific structures of the translation device 4, lifting device one 6 and lifting device two 21.

[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
