Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a vibrating fluidized bed. Background Art

[0002] In the production process of APIs (e.g. potassium chloride), the product usually needs to go through the processes of dissolution and refining - filtration - concentration - cooling and crystallization - centrifugal separation - drying - mixing - inner packaging - outer packaging, etc. In the drying process, a vibrating fluidized bed is usually used to dry the API. During operation, the material enters the vibrating fluidized bed from the feed port. Under the action of the vibration force, the material moves forward continuously along the length direction of the sieve plate. In this process, the hot air passes through the sieve plate and exchanges heat with the wet material, thereby drying the API. The dried API is finally discharged from the discharge port.

[0003] However, due to the limitations of technology and equipment, the intermediate products after drying contain impurities such as black residue and foreign matter, which reduces the quality of the product and increases the production cost. Summary of the invention

[0057] like Figure 1 As shown, the present invention provides a vibrating fluidized bed, comprising a body 100 having a feed port and a discharge port, and a sieve plate 200 and a vibration motor 300 arranged on the body 100. The sieve plate 200 is movably connected to the body 100, and the sieve plate 200 is tilted so that the material can move along the sieve plate 200 toward the discharge port under the action of the vibration force. The vibration motor 300 is fixedly mounted on the body 100, and the vibration motor 300 is transmission-connected to the sieve plate 200 to drive the sieve plate 200 to vibrate.

[0058] like Figure 1 As shown, the vibrating fluidized bed provided by the present invention further comprises a screening device 400, and the screening device 400 is used to screen out impurities in the material, such as foreign matter and black slag.

[0059] After analysis, it was found that the black slag and foreign matter were mainly magnetic impurities in the material itself and metal impurities introduced into the equipment. Figure 2-19 As shown, the screening device 400 includes a housing 410 and a magnetic bar set.

[0060] The shell 410 is hollow and has a feed port and a discharge port. The shell 410 is disposed at the discharge port of the body 100 , and the feed port of the shell 410 is communicated with the discharge port of the body 100 .

[0061] The magnetic rod group is arranged in the housing 410, and there are multiple groups of magnetic rod groups, and the multiple groups of magnetic rod groups are arranged in sequence and at intervals along the longitudinal direction. Each group of magnetic rod groups has multiple magnetic rods 420, and the axis of the magnetic rod 420 is along the first horizontal direction. The multiple magnetic rods 420 in each group of magnetic rod groups are arranged in sequence and at intervals along the second horizontal direction, wherein the first horizontal direction is perpendicular to the second horizontal direction.

[0062] When the material passes through the magnetic rod group, the magnetic impurities and metal impurities in the material are adsorbed on the magnetic rod 420 under the magnetic force of the magnetic rod 420, and the material flows out from the gap between two adjacent magnetic rods 420, thereby achieving the purpose of screening out impurities in the material. Specifically, the impurities are magnetic impurities and metal impurities.

[0063] The vibrating fluidized bed provided by the present invention can screen out impurities mixed in the dried intermediate product through the screening device 400, thereby improving the quality of the product.

[0064] Specifically, in this embodiment, two groups of magnetic rod groups are provided, and the number of magnetic rods in the lower group of magnetic rods is one more than the number of magnetic rods in the upper group of magnetic rods. For example, the number of magnetic rods in the upper group of magnetic rods is 3, and the number of magnetic rods in the lower group of magnetic rods is 4, the number of magnetic rods in the upper group of magnetic rods is 5, and the number of magnetic rods in the lower group of magnetic rods is 6.

[0065] Preferably, the multiple magnetic bars 420 of any two adjacent groups of magnetic bars are staggered so that the material flowing out from the gap between two adjacent magnetic bars 420 of the previous group of magnetic bars falls onto the magnetic bars 420 of the next group of magnetic bars, thereby achieving the purpose of improving the screening efficiency.

[0066] Preferably, the gap between any two adjacent magnetic bars 420 in each group of magnetic bars is less than or equal to the diameter of the magnetic bar 420, so that the material flowing out from the gap between two adjacent magnetic bars 420 of the previous group of magnetic bars can completely fall onto the magnetic bars 420 of the next group of magnetic bars, thereby achieving the purpose of further improving the screening effect.

[0067] Alternatively, if Figure 2-19 As shown, the screening device 400 further includes mounting racks 430 , the number of mounting racks 430 is equal to and corresponds to the number of magnetic bar groups, the mounting racks 430 and the housing 410 are arranged in a drawer structure, and the magnetic bar groups are arranged on the mounting racks 430 .

[0068] When it is necessary to clean the impurities on the magnetic rod 420 , the mounting frame 430 can be pulled out, thereby achieving the purpose of facilitating the cleaning of the impurities on the magnetic rod 420 .

[0069] Preferably, a locking mechanism for locking the mounting frame is provided on the mounting frame 430 and the shell 410. The locking structure may be a combination of a latch and a socket, or a snap lock structure, etc., which will not be elaborated here and is not shown in the drawings.

[0070] Alternatively, if Figure 2-19 As shown, the screening device 400 also includes a driving mechanism, the magnetic rod 420 is rotatably connected to the mounting frame 430, the driving mechanism is arranged on the mounting frame 430 and the shell 410, and the driving mechanism is used to drive the magnetic rod 420 to rotate so that the circumferential wall of the magnetic rod 420 can evenly adsorb impurities.

[0071] Specifically, Figure 4 , 6 As shown in Figures 9, 11, 14 and 16, the driving mechanism includes a driving motor 510, a synchronous wheel set and a transmission structure.

[0072] The driving motor 510 is fixedly mounted on the housing 410, and the synchronous wheel group is arranged on the mounting frame 430. The number of synchronous wheels 520 of the synchronous wheel group is equal to and corresponds to the number of magnetic bars 420 of the corresponding magnetic bar group. The synchronous wheel 520 is rotationally connected to the mounting frame 430, the synchronous wheel 520 is coaxially arranged with the magnetic bar 420 and is transmission-connected to the magnetic bar 420, and any two adjacent synchronous wheels 520 are transmission-connected through a synchronous belt 530.

[0073] The transmission structure is disposed on the mounting frame 430 and the housing 410 , and is used to transmit the power of the driving motor 510 to one of the synchronous wheels 520 .

[0074] Alternatively, if Figure 4 , 6As shown in Figures 7, 8, 9, 11, 12 and 13, the transmission structure includes a first transmission shaft 610, a second transmission shaft 620, a first transmission element 630, a second transmission element 640, a first elastic element 650 and a limiting assembly.

[0075] The first transmission shaft 610 is rotatably connected to the mounting frame 430, and the first transmission shaft 610 is coaxially arranged with the corresponding synchronous wheel 520 and is in transmission connection with the synchronous wheel 520. The second transmission shaft 620 is rotatably connected to the housing 410, and the second transmission shaft 620 is in transmission connection with the power output shaft of the driving motor 510. The first transmission element 630 is sleeved on the end of the first transmission shaft 610 away from the synchronous wheel 520 and is fixedly connected to the first transmission shaft 610. The second transmission element 640 is sleeved on the end of the second transmission shaft 620 facing the first transmission element 630 and is slidably connected to the second transmission shaft 620, so that the second transmission element 640 can move along the axis direction of the second transmission shaft 620, but cannot rotate relative to the second transmission shaft 620. In this embodiment, the first transmission element 630 and the second transmission element 640 are both transmission disks.

[0076] The first elastic element 650 is sleeved on the second transmission shaft 620, and the two ends of the first elastic element 650 are connected to the second transmission shaft 620 and the second transmission element 640 respectively, and in the natural state, the first elastic element 650 is used to apply elastic force to the second transmission element 640, so that the second transmission element 640 has a tendency to move in the direction close to the first transmission element 630. Among them, the first elastic element 650 can be any element that can apply elastic force to the second transmission disk, such as: a spring, a gas spring, a hydraulic spring, a rubber spring, etc. In this embodiment, the first elastic element 650 is a spring. The limiting assembly is arranged on the first transmission element 630 and the second transmission element 640, so that the second transmission element 640 can drive the first transmission element 630 to rotate through the limiting assembly.

[0077] Alternatively, if Figure 4 , 6 As shown in , 7 and 8, the limiting assembly includes a limiting pin 631.

[0078] The limiting pin 631 is disposed on a side of the first transmission element 630 facing the second transmission element 640 and is fixedly connected to the first transmission element 630. The second transmission element 640 is correspondingly provided with a limiting hole 641.

[0079] During operation, the limiting pin 631 is inserted into the limiting hole 641 , and the cooperation between the limiting pin 631 and the limiting hole 641 enables the second transmission element 640 to transmit power to the first transmission element 630 , thereby driving the first transmission element 630 to rotate.

[0080] When it is necessary to pull out the mounting frame 430 to clean the impurities on the magnetic rod 420 or replace the magnetic rod 420, the mounting frame 430 can be directly pulled outward to separate the limiting pin 631 from the limiting hole 641, which is easy to operate. At the same time, when it is necessary to push the mounting bracket 430 into the shell 410, assuming that the limit pin 631 does not correspond to the limit hole 641, the limit pin 631 pushes the second transmission element 640 to overcome the elastic force of the first elastic element 650 and move, so it will not affect pushing the mounting bracket 430 into the shell 410. Then the driving motor 510 drives the second transmission shaft 620 to rotate, and the second transmission shaft 620 drives the second transmission element 640 to rotate. When the second transmission element 640 rotates to a position where the limit pin 631 corresponds to the limit hole 641, the first elastic element 650 drives the second transmission element 640 to move toward the direction close to the first transmission element 630, so that the limit pin 631 is inserted into the limit hole 641. With the cooperation of the limit pin 631 and the limit hole 641, the second transmission element 640 can transmit power to the first transmission element 630 to drive the first transmission element 630 to move.

[0081] Therefore, the limiting assembly provided in this embodiment can arbitrarily pull the mounting frame 430 out of the shell 410, and can also arbitrarily insert the mounting frame 430 into the shell 410, which greatly improves the efficiency of pulling out and pushing the magnetic rod 420 into the shell 410.

[0082] Preferably, a plurality of limiting pins 631 and a plurality of limiting holes 641 are provided to improve the stability and reliability of power transmission.

[0083] Preferably, a universal ball 660 is provided at the free end of the limit pin 631 to reduce friction when the limit pin 631 and the second transmission element 640 slide relative to each other, and the ball is spherical, forming a cone-like structure at the free end of the limit pin 631 to facilitate the insertion of the limit pin 631 into the limit hole 641.

[0084] Alternatively, if Fig. 9 , 11 As shown in FIGS. 12 and 13 , the limiting assembly includes a first limiting tooth group 632 arranged on a side of the first transmission element 630 facing the second transmission element 640 and a second limiting tooth group 642 arranged on a side of the second transmission element 640 facing the first transmission element 630 .

[0085] During operation, under the cooperation of the first limiting tooth set 632 and the second limiting tooth set 642 , the second transmission element 640 can transmit power to the first transmission element 630 , thereby driving the first transmission element 630 to rotate, and further driving the magnetic rod 420 to rotate.

[0086] When it is necessary to pull out the mounting frame 430 to clean the impurities on the magnetic rod 420 or replace the magnetic rod 420, the mounting frame 430 can be directly pulled out to separate the first limiting tooth group 632 and the second limiting tooth group 642, which is easy to operate. At the same time, when it is necessary to push the mounting bracket 430 into the shell 410, assuming that the first limiting tooth group 632 and the second limiting tooth group 642 do not correspond, the first limiting tooth group 632 pushes the second transmission element 640 to overcome the elastic force of the first elastic element 650 and move, so it will not affect the pushing of the mounting bracket 430 into the shell 410. Then the driving motor 510 drives the second transmission shaft 620 to rotate, and the second transmission shaft 620 drives the second transmission element 640 to rotate. When the second transmission element 640 rotates to a position where the first limiting tooth group 632 and the second limiting tooth group 642 correspond to each other, the first elastic element 650 drives the second transmission element 640 to move in a direction close to the first transmission element 630, so that the first limiting tooth group 632 and the second limiting tooth group 642 are meshed with each other. Under the cooperation of the first limiting tooth group 632 and the second limiting tooth group 642, the second transmission element 640 can transmit power to the first transmission element 630 to drive the first transmission element 630 to move.

[0087] Therefore, the limiting assembly provided in this embodiment can arbitrarily pull the mounting frame 430 out of the shell 410, and can also arbitrarily insert the mounting frame 430 into the shell 410, which greatly improves the efficiency of pulling out and pushing the magnetic rod 420 into the shell 410.

[0088] Alternatively, if Fig.14 , 16 As shown in FIGS. 17 , 18 and 19 , the transmission structure includes a third transmission shaft 710 , a fourth transmission shaft 720 , a third transmission element 730 , a fourth transmission element 740 and a limiting element 750 .

[0089] The third transmission shaft 710 is rotatably connected to the mounting frame 430 , and is coaxially arranged with the corresponding synchronous wheel 520 and is in transmission connection with the synchronous wheel 520 . The fourth transmission shaft 720 is rotatably connected to the housing 410 , and is in transmission connection with the driving motor 510 .

[0090] The fourth transmission element 740 is arranged at one end of the fourth transmission shaft 720 facing the third transmission shaft 710, and the side of the fourth transmission element 740 facing the fourth transmission shaft 720 has a spherical first connecting portion 741, and the end of the fourth transmission shaft 720 facing the third transmission shaft 710 has a second connecting portion 721, and the second connecting portion 721 has a connecting groove 722 adapted to the first connecting portion 741.

[0091] A limiting element 750 is provided on the side wall of the first connection portion 741, and the limiting element 750 is arc-shaped. The limiting element 750 is hinged to the side wall of the first connection portion 741, and the inner side wall of the connecting groove 722 is provided with a limiting groove 723 matched with the limiting element 750. In the working state, the limiting element 750 is matched with the limiting groove 723, so that the fourth transmission shaft 720 can transmit power to the fourth transmission element 740 to drive the fourth transmission element 740 to rotate.

[0092] The third transmission element 730 is sleeved on one end of the third transmission shaft 710 away from the synchronous wheel 520 and fixedly connected to the third transmission shaft 710 , and the end surface of the third transmission element 730 away from the synchronous wheel 520 is inclined relative to the axis of the third transmission shaft 710 .

[0093] In the working state, the end surface of the third transmission element 730 facing the fourth transmission element 740 fits with the end surface of the fourth transmission element 740 facing the third transmission element 730, so that the fourth transmission element 740 can drive the third transmission element 730 to rotate.

[0094] During operation, the end face of the third transmission element 730 facing the fourth transmission element 740 fits with the end face of the fourth transmission element 740 facing the third transmission element 730. Therefore, the fourth transmission element 740 can transmit power to the third transmission element 730, thereby driving the third transmission element 730 to rotate, and then driving the magnetic rod 420 to rotate.

[0095] When it is necessary to pull out the mounting frame 430 to clean the impurities on the magnetic rod 420 or replace the magnetic rod 420, the mounting frame 430 can be directly pulled out to separate the third transmission element 730 from the fourth transmission element 740, which is easy to operate. At the same time, when it is necessary to push the mounting bracket 430 into the shell 410, assuming that the end face of the third transmission element 730 facing the fourth transmission element 740 does not correspond to the end face of the fourth transmission element 740 facing the third transmission element 730. Since the fourth transmission element 740 is connected to the fourth transmission shaft 720 through a spherical secondary structure, the third transmission element 730 will push the fourth transmission element 740 to rotate, so that the end wall of the fourth transmission element 740 facing the third transmission element 730 moves to a position that fits with the end face of the third transmission element 730 facing the fourth transmission element 740, thereby not affecting the pushing of the mounting bracket 430 into the shell 410. Then, the driving motor 510 drives the fourth transmission shaft 720 to rotate, the fourth transmission shaft 720 drives the fourth transmission element 740 to rotate, the fourth transmission element 740 drives the third transmission element 730 to rotate, and the third transmission element 730 drives the four scattered transmission shafts to rotate, thereby achieving the purpose of driving the magnetic rod 420 to rotate.

[0096] Therefore, the transmission structure provided in this embodiment can arbitrarily pull the mounting frame 430 out of the shell 410, and can also arbitrarily insert the mounting frame 430 into the shell 410, which greatly improves the efficiency of pulling out and pushing the magnetic rod 420 into the shell 410.

[0097] Preferably, anti-skid pads are provided on opposite sides of the third transmission element 730 and the fourth transmission element 740 to increase the friction between the third transmission element 730 and the fourth transmission element 740 to prevent relative sliding between the third transmission element 730 and the fourth transmission element 740, thereby improving the reliability and stability of the transmission.

[0098] Preferably, the outer side wall of the first connection part 741 and the inner side wall of the connection groove 722 are provided with anti-slip pads to increase the friction between the first connection part 741 and the connection groove 722, so that relative rotation between the first connection part 741 and the connection groove 722 will not easily occur, thereby achieving the purpose of improving the reliability and stability of the transmission.

[0099] Alternatively, if Figure 4 , 5 As shown in Figures , 6, 7, 9, 10, 11, 12, 14, 15, 16, and 18, the magnetic rod 420 is detachably connected to the mounting bracket 430 to facilitate replacement of the magnetic rod 420.

[0100] Specifically, the magnetic rod 420 is transmission-connected to the synchronous wheel 520 via the power input shaft 810. A first connection socket 421 is provided at the first end of the magnetic rod 420, and the cross section of the first connection socket 421 is circular. The mounting frame 430 is correspondingly provided with a first connection element 820, the first connection element 820 is slidably connected to the mounting frame 430, and the first connection element 820 is correspondingly provided with a third connection portion 821 adapted to the first connection socket 421.

[0101] The mounting frame 430 is provided with a second elastic element 830, and the two ends of the second elastic element 830 are respectively in contact with the first connecting element 820 and the mounting frame 430, and in a natural state, the second elastic element 830 applies elastic force to the first connecting element 820, so that the first connecting element 820 has a tendency to move toward the direction close to the magnetic rod 420. The second elastic element 830 can be any element that can apply elastic force to the first connecting element 820, such as a spring, a gas spring, a hydraulic spring, a rubber spring, etc. In this embodiment, the second elastic element 830 is a spring.

[0102] A second connecting socket 422 is provided on the end face of the second end of the magnetic rod 420, and the cross-section of the second connecting socket 422 is non-circular, for example, polygonal, elliptical, cross-shaped, etc., so that when the second connecting socket 422 is matched with the second connecting element 840, the power input shaft 810 can drive the magnetic rod 420 to rotate.

[0103] The power input shaft 810 is sleeved with a second connecting element 840, which is slidably connected to the power input shaft 810, so that the second connecting element 840 can move along the axis of the power input shaft 810, but cannot rotate relative to the power input shaft 810. The second connecting element 840 has a fourth connecting portion 841 that is compatible with the second connecting socket 422. In the working state, the second connecting socket 422 and the fourth connecting portion 841 cooperate with each other, so that the power input shaft 810 can transmit power to the magnetic rod 420 to drive the magnetic rod 420 to rotate.

[0104] The power input shaft 810 is sleeved with a third elastic element 850, and the two ends of the third elastic element 850 are respectively in contact with the second connecting element 840 and the power input shaft 810, and in a natural state, the third elastic element 850 applies elastic force to the second connecting element 840, so that the second connecting element 840 has a tendency to move in a direction close to the magnetic rod 420. The third elastic element 850 can be any element that can apply elastic force to the second connecting element 840, such as a spring, a gas spring, a hydraulic spring, a rubber spring, etc. In this embodiment, the third elastic element 850 is a spring.

[0105] When the magnetic rod 420 needs to be disassembled, the first connecting element 820 and the second connecting element 840 are moved to separate the third connecting portion 821 from the first connecting hole 421 and the fourth connecting portion 841 from the second connecting hole 422, and the magnetic rod 420 can be taken out, which is easy to operate.

[0106] When installing the magnetic rod 420, move the first connecting element 820 and the second connecting element 840 so that the third connecting part 821 and the fourth connecting part 841 retract into the side wall of the mounting frame 430, insert the magnetic rod 420, and under the action of the elastic force of the second elastic element 830 and the third elastic element 850, insert the third connecting part 821 into the first connecting hole 421 and the fourth connecting part 841 into the second connecting hole 422, so as to achieve the purpose of installing the magnetic rod 420, and the operation is convenient.

[0107] This structure facilitates the installation and removal of the magnetic bar 420 , and greatly improves the efficiency of removing and installing the magnetic bar 420 .

[0109] Optionally, a driving element 860 is sleeved on the second connecting element 840 , and the driving element 860 is rotatably connected to the second connecting element 840 . The driving element 860 has a second operating portion 861 extending outside the side wall of the mounting frame 430 to drive the second connecting element 840 to move.
