Description

Technical Field

[0001] The present invention relates to the technical field related to continuous crystallizers, and in particular to a rotary feeding device for a continuous crystallizer. Background Art

[0002] The continuous crystallizer is a common reaction device in chemical production. The inlet and outlet materials of the continuous crystallizer as well as the concentration, temperature, slurry density and crystal particle size distribution of the internal liquid remain unchanged during production and operate in a steady state, and the crystallized product can be obtained continuously and stably.

[0003] The material needs to be fully diffused in the continuous crystallizer to better react and crystallize. However, when feeding, the existing continuous crystallizers mostly directly inject the raw materials into the crystallizer in a direct spraying manner. After the material enters the continuous crystallizer in this way, it still needs a long time of diffusion and distribution to fully react, which reduces the reaction and crystallization efficiency of the continuous crystallizer.

[0004] Some continuous crystallizers have simple improvements to the feed inlet, such as adding a rotating nozzle or shower head to the original direct injection inlet to achieve the purpose of pre-dispersing the incoming liquid. However, the feed flow rate of the material varies for different reactions. When the material feed flow rate is low, the water flow from the rotating nozzle may not be able to drive the rotating nozzle to rotate, and the water flow from the shower head will also have a weak diffusion effect. In other words, the existing material diffusion structure is not ideal when the feed flow rate is low.

[0005] At the same time, the diffusion effect of the material in the existing technology, such as the rotary nozzle or the shower head, cannot be adjusted without changing the feed flow rate. In some cases, technicians need to reasonably adjust the diffusion effect of the material to control the reaction rate without changing the feed flow rate. Obviously, the existing material diffusion device is difficult to meet the control needs of technicians. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] Reference Figure 1-8 , a continuous crystallizer rotary feeding device will be described in detail below.

[0032] A continuous crystallizer rotary feeding device includes a feeding pipe 1, an installation component 2, a diffusion component 3, a flow adjustment component 4 and a rotating component 5. The feeding pipe 1 includes a feeding pipe 11, an installation chamber 12 and a transfer pipe 13 that are connected in sequence. The flow adjustment component 4 is arranged in the installation chamber 12, the diffusion component 3 is arranged outside the transfer pipe 13, the installation component 2 is arranged outside the diffusion component 3, the rotating component 5 is partially arranged in the inner cavity of the installation chamber 12, and the rotating component 5 is transmission-connected to the diffusion component 3.

[0033] The transfer tube 13 is arranged perpendicular to the feed tube 11 , and at least one discharge port 1301 is formed at the lower end of the transfer tube 13 .

[0034] The diffusion assembly 3 includes a sleeve 31, a first bevel gear 32, a material storage chamber 33, and a diffusion tube 34. The sleeve 31 is axially rotatably mounted on the outside of the transfer tube 13. When the sleeve 31 is mounted on the outside of the transfer tube 13, the material storage chamber 33 corresponds to the discharge port 1301. The diffusion tube 34 is connected and mounted on the outer peripheral wall of the material storage chamber 33 and is provided with a plurality of spray ports. The sleeve 31, along with the material storage chamber 33 and the diffusion tube 34, can axially rotate on the outside of the transfer tube 13. Material flows from the discharge port 1301 into the material storage chamber 33, enters the diffusion tube 34 from the material storage chamber 33, and is ultimately sprayed out of the spray ports, achieving effective diffusion feeding of the material.

[0035] The mounting assembly 2 includes a rotating ring 21 and a mounting flange 22. The rotating ring 21 is mounted outside the sleeve 31 and above the diffuser 34. The rotating ring 21 can rotate along with the sleeve 31. The mounting flange 22 surrounds the rotating ring 21 and is connected to the rotating ring 21 by a bearing. The mounting flange 22 can be fixedly mounted at the feed port of the continuous crystallizer, while the rotating ring 21 can rotate axially within the fixed mounting flange 22.

[0036] The flow adjustment component 4 includes a docking moving part 41, an adjusting screw 42 and a driven rack 43. The docking moving part 41 is spliced ​​around to form a "U"-shaped structure, and a flow channel 401 is formed in the center. The adjusting screw 42 is vertically installed and connected to the two horizontally arranged docking moving parts 41 screw rods. The driven rack 43 is horizontally installed on the outside of the two vertically arranged docking moving parts 41.

[0037] The docking movable member 41 includes a driven block 411, a telescopic block 412 and a permanent magnet 413. The driven block 411 is a cubic block, and a pair of parallel faces among the six faces of the driven block 411 are defined as faces A. The driven block 411 is hollow inside and passes through two long faces A to the outside. The telescopic block 412 is a quadrangular prism with a right-angled trapezoidal bottom face. The bottom angle of the right-angled trapezoidal bottom face of the telescopic block 412 is forty-five degrees. The face where the right-angled side of the telescopic block 412 trapezoid is located is defined as face B, and the face where the hypotenuse of the telescopic block 412 is located is defined as face C. The end where the face B of the telescopic block 412 is located faces the long face A of the driven block 411 and can be movably and tightly inserted into the interior of the driven block 411. Two telescopic blocks 412 are inserted into one of the driven blocks 411. After the two telescopic blocks 412 are inserted into the driven block 411, the C faces are not parallel to each other.

[0038] The horizontally arranged telescopic block 412 and the vertically arranged telescopic block 412 are closely connected to each other so as to stabilize the "U"-shaped structure formed by the docking movable member 41. It is understood that when the horizontally arranged telescopic block 412 moves vertically, it can drive the connected vertically arranged telescopic block 412 to move. Similarly, when the vertically arranged telescopic block 412 moves horizontally, it can drive the connected horizontally arranged telescopic block 412 to move.

[0039] A driving piece 44 is mounted horizontally on the side of the horizontally arranged driven block 411, extending in the direction of movement of the telescopic block 412. A threaded hole is defined at the end of the driving piece 44, distal from the driven block 411. The adjusting screw 42 passes through the threaded hole and is threadedly connected to the driving piece 44. The threads on the upper and lower portions of the adjusting screw 42 are in opposite directions, so that when the adjusting screw 42 rotates, the two horizontally arranged driven blocks 411 move in opposite directions.

[0040] The vertically arranged driven block 411 is horizontally installed with a driven rack 43, and the driven rack 43 is extended toward the adjusting screw 42. The adjusting screw 42 is provided with a toothed ring 45 at a position close to the driven rack 43. The toothed ring 45 is engaged with the driven rack 43. When the adjusting screw 42 rotates, it can drive the driven rack 43 to move horizontally.

[0041] The distance L1 that the adjusting screw 42 drives the horizontally arranged driven block 411 to move when it rotates one circle is equal to, and the distance L2 that the vertically arranged driven block 411 drives to move when the toothed ring 45 rotates one circle is equal to, L1.

[0042] The driven block 411 has a groove on one side facing the other, and the permanent magnet 413 is installed in the groove. The thickness of the permanent magnet 413 is less than the depth of the groove. The permanent magnet 413 is connected to the bottom surface of the groove through a spring, so that the permanent magnet 413 can protrude from the groove to a certain extent under the action of external force, and be pulled back into the groove by the spring after the external force is withdrawn.

[0043] The installation chamber 12 is a hollow cube, with the feed pipe 11 and the transfer pipe 13 mounted on opposite sides of the installation chamber 12. Both the feed pipe 11 and the transfer pipe 13 are connected to the interior of the installation chamber 12. The internal dimensions of the installation chamber 12 allow the flow adjustment assembly 4 to be placed therein. The flow adjustment assembly 4 is arranged in the installation chamber 12 such that the flow channel 401 connects the feed pipe 11 and the transfer pipe 13.

[0044] The inner wall of the installation chamber 12 is provided with a guide groove 1201 extending cross-symmetrically at the entrance of the feed pipe 11 and the transfer pipe 13. Each of the driven blocks 411 is movably and tightly connected to the guide groove 1201 so as to move horizontally or vertically under the guidance of the guide groove 1201.

[0045] The guide groove 1201 is sunken into the inner wall of the installation chamber 12 to a certain depth, so that after the driven block 411 is placed in the guide groove 1201, the telescopic block 412 is tightly attached to the inner wall of the installation chamber 12. The driven block 411 and the telescopic block 412 are attached to the inner wall of the installation chamber 12 at the connection between the feed pipe 11 and the transfer pipe 13, so that the material entering the installation chamber 12 can only flow within the circulation channel 401.

[0046] The installation chamber 12 also allows a driven rack 43 and an adjusting screw 42 to be arranged therein, wherein the adjusting screw 42 can be axially rotatably arranged in the installation chamber 12, and at least one end of the adjusting screw 42 can be protruded from the installation chamber 12, so that a technician can adjust the flow adjustment assembly 4 outside the installation chamber 12.

[0047] The rotating assembly 5 includes a self-adjusting paddle 51, a rotating shaft 52 and a second bevel gear 53. The self-adjusting paddle 51 and the second bevel gear 53 are respectively installed at both ends of the rotating shaft 52. The second bevel gear 53 is engaged with the first bevel gear 32. The self-adjusting paddle 51 is set at the circulation channel 401. The material flowing in the circulation channel 401 will push the self-adjusting paddle 51 to rotate, so that the rotating shaft 52 drives the second bevel gear 53 to rotate, and finally the sleeve 31 is rotated through the transmission of the second bevel gear 53 and the first bevel gear 32.

[0048] The self-adjusting blades 51 are symmetrically arranged on the outer circumference of the rotating shaft 52. The self-adjusting blades 51 include a fixed blade 511, a telescopic blade 512, an energized rod 513, an outer electromagnetic block 514, an inner electromagnetic block 515 and a positioning head 516. The fixed blade 511 is hollow inside and is fixedly installed on the outside of the rotating shaft 52. The end of the fixed blade 511 away from the rotating shaft 52 is open. The telescopic blade 512 is hollow inside and can be movably inserted into the fixed blade 511 from the opening. The inner wall of the fixed blade 511 is provided with at least one row of locking teeth 517 along the moving direction of the telescopic blade 512.

[0049] The outer electromagnetic block 514 is installed at the end of the telescopic leaf 512 extending to the outside of the fixed leaf 511, the power rod 513 extends from the rotating shaft 52 to the outer electromagnetic block 514, and the inner electromagnetic block 515 is installed on the outer peripheral wall of the power rod 513. The side wall of the telescopic leaf 512 is provided with an opening corresponding to the locking tooth 517 to allow the positioning head 516 to protrude. The positioning head 516 is connected to the spring of the power rod 513. When the spring is at normal length, the positioning head 516 is pushed out and engaged with the locking tooth 517, thereby locking the position of the telescopic leaf 512.

[0050] The inside of the power rod 513 is provided with wires electrically connected to the outer electromagnetic block 514 and the inner electromagnetic block 515 respectively. After the wires input electricity to the outer electromagnetic block 514 and the inner electromagnetic block 515, they can generate strong magnetism. The end of the positioning head 516 facing the inner electromagnetic block 515 has permanent magnetism. After the inner electromagnetic block 515 is energized to generate magnetism, the positioning head 516 will be attracted by the magnetic force and approach the inner electromagnetic block 515, thereby disengaging from the locking tooth 517. At this time, the telescopic leaf 512 can move freely in the fixed leaf 511.

[0051] After generating magnetism, the external electromagnetic block 514 will be attracted by the permanent magnet piece 413 and pull the telescopic blade 512 toward the permanent magnet piece 413. After being energized, the self-adjusting blade 51 can adjust the blade to a length that matches the flow channel 401 by means of magnetic attraction according to the position of the driven block 411, so that the material flowing in the flow channel 401 can efficiently drive the self-adjusting blade 51 to rotate.

[0052] When the permanent magnet piece 413 is attracted by the electromagnetic force of the outer electromagnetic block 514, it will move a certain distance from the groove of the driven block 411, so that the outer electromagnetic block 514 maintains a certain distance from the driven block 411. After the outer electromagnetic block 514 and the inner electromagnetic block 515 are powered off, the magnetism disappears, and the positioning head 516 is rebounded to its original position by the spring and re-locks the telescopic leaf 512. The permanent magnet piece 413 will also rebound into the groove and maintain a certain distance from the outer electromagnetic block 514. The telescopic leaf 512 can be adjusted to a position closest to the driven block 411 without being affected by the rotation of the driven block 411.

[0053] The wires in the power rod 513 extend to the rotating shaft 52 and extend along the rotating shaft 52 to the outside of the second bevel gear 53. A controller 54 is installed on the outside of the second bevel gear 53. The controller 54 can be installed with a power source such as a dry cell or a rechargeable battery. Technicians can control the power on and off of the outer electromagnetic block 514 and the inner electromagnetic block 515 through the controller 54 from the outside.

[0054] The material enters the circulation channel 401 through the feed pipe 11 at a fixed flow rate. The technician can adjust the position of each docking moving part 41 with the help of the adjusting screw 42 when the outer electromagnetic block 514 and the inner electromagnetic block 515 are energized, thereby adjusting the inner side length of the circulation channel 401, and then changing the flow rate of the material entering the circulation channel 401. The self-adjusting paddle 51 can also change its own length as the docking moving part 41 moves under the action of magnetic force. After the adjustment is completed, the technician will de-energize the outer electromagnetic block 514 and the inner electromagnetic block 515. The material can then efficiently push the rotating component 5 to rotate in the circulation channel 401 at the required flow rate, thereby adjusting the diffusion effect of the material entering at a fixed feed flow rate. If the feed flow rate is low, technicians can adjust the docking moving part 41 to make the inner side length of the circulation channel 401 smaller, so as to increase the flow rate of the material flowing into the circulation channel 401, so that the material entering at a low speed can push the rotating component 5 to rotate rapidly under the acceleration of the circulation channel 401, thereby ensuring the diffusion effect of the material.
