Description

Technical Field

[0001] This application relates to the technical field of guanidine hydrochloride preparation, and in particular to an apparatus for preparing guanidine hydrochloride. Background Technology

[0002] Guanidine hydrochloride is an organic compound produced from cyanamide and ammonium salts. It is a white or slightly yellow lumpy substance used as an intermediate in pharmaceuticals, pesticides, dyes, and other organic synthesis. It is an important raw material for the manufacture of sulfonamide drugs and folic acid, and can also be used as an antistatic agent for synthetic fibers. Filtration is required during production.

[0003] The related technology describes a filtration device for guanidine hydrochloride production, which includes a filter barrel, a bottom plate, a filter element, a support frame, and a connecting groove. The support frame is installed inside the filter barrel, and the filter element is fixed on the support frame. The bottom plate is located at the bottom of the filter barrel and spaced apart from the filter element. An outlet is provided on the bottom plate, and an inlet communicating with the filter element is provided at the top of the filter barrel. When filtration is required, the guanidine hydrochloride solution is poured into the filter element through the inlet, filtered by the filter element, and then discharged through the outlet.

[0004] In the aforementioned technologies, after filtering guanidine hydrochloride, impurities adhere to the filter element. Cleaning requires removing the filter element from the support frame, which is cumbersome and inconvenient for removing impurities. Summary of the Invention

[0005] To facilitate the removal of impurities, this application provides a guanidine hydrochloride preparation apparatus.

[0006] The guanidine hydrochloride preparation apparatus provided in this application adopts the following technical solution: A guanidine hydrochloride preparation device includes a frame and a filter barrel mounted on the frame. The bottom of the filter barrel has a filter hole for filtering guanidine hydrochloride. The bottom of the filter barrel is connected to a collection component for collecting guanidine hydrochloride. The top of the filter barrel is provided with a mounting plate. The mounting plate is provided with a cleaning device for cleaning impurities. The frame is provided with an auxiliary device for collecting impurities. The auxiliary device is connected to the bottom of the filter barrel. The mounting plate is slidably mounted on the filter barrel. The mounting plate is provided with a feed pipe for feeding materials. The feed pipe and the cleaning device are spaced apart.

[0007] By adopting the above technical solution, after filtering guanidine hydrochloride, the guanidine hydrochloride is collected by the collection component. When it is necessary to clean the impurities, the position of the mounting plate is moved to the filter bucket, and the cleaning device is moved to the filter bucket to clean the impurities.

[0008] Optionally, the collection assembly includes a collection bucket, a collection frame, and a collection tube. The collection bucket is located on one side of the frame, the collection frame is located at the bottom of the filter bucket, the collection frame is connected to the filter holes, and one end of the collection tube is connected to the collection bucket and the other end is connected to the collection frame.

[0009] By adopting the above technical solution, when filtering guanidine hydrochloride, the guanidine hydrochloride enters the collection frame and then enters the collection bucket through the collection tube to clean the filtered guanidine hydrochloride.

[0010] Optionally, the cleaning device includes a pushing component, a rotating component, a mounting plate, and a cleaning brush. A partition is provided between the mounting plate and the side of the mounting plate facing away from the filter barrel. A cleaning port is provided through the mounting plate at a position corresponding to the partition. The pushing component is disposed on the partition, and the output end of the pushing component passes through the partition and faces the mounting plate. The rotating component is disposed at the output end of the pushing component. The mounting plate is disposed at the output end of the rotating component. The cleaning brush is disposed on the side of the mounting plate near the filter barrel for cleaning impurities on the bottom of the filter barrel.

[0011] By adopting the above technical solution, when it is necessary to clean impurities, the mounting plate moves the mounting disc to the opening of the filter barrel, the pushing component moves the mounting disc and cleaning brush to the bottom of the filter barrel, and then the rotating component drives the mounting disc to rotate, which in turn drives the cleaning brush to rotate, thereby cleaning the impurities.

[0012] Optionally, a placement plate is slidably mounted on the frame, and an auxiliary device is mounted on the placement plate. The auxiliary device includes an auxiliary bucket, an auxiliary tube, and an auxiliary plate. The auxiliary bucket is mounted on the placement plate, and the auxiliary plate has a hollow structure. The auxiliary tube is positioned between the auxiliary plate and the auxiliary bucket to connect the two. A first insertion port is provided at the bottom of the filter bucket, and a second insertion port is provided on the collection frame. The first and second insertion ports are located in the same vertical plane. The auxiliary plate is slidably mounted within the first and second insertion ports, and an opening is provided on the side of the auxiliary plate closest to the first insertion port.

[0013] By adopting the above technical solution, when the cleaning brush cleans the impurities, the moving placement plate moves the auxiliary plate into the first inlet, aligning the opening on the auxiliary plate with the bottom of the filter bucket. When the cleaning brush cleans the impurities at the bottom of the filter bucket, it moves the impurities to the opening of the auxiliary plate, and then into the auxiliary plate. The impurities are then collected through the auxiliary pipe into the auxiliary bucket.

[0014] Optionally, the placement plate is slidably mounted on the frame in the same direction as the mounting plate, and an intermediate rod is provided between the placement plate and the mounting plate to connect the two. The frame is provided with a control component for adjusting the position of the placement plate, and the output end of the control component is connected to the placement plate.

[0015] By adopting the above technical solution, when the control component moves the placement plate, it moves the mounting plate through the intermediate rod, thereby simultaneously adjusting the positions of the auxiliary bucket and the mounting plate. While adjusting the position of the cleaning brush, the position of the auxiliary plate is also adjusted, thus improving the cleaning efficiency of impurities.

[0016] Optionally, the bottom wall of the filter barrel is provided with an installation port that communicates with the first inlet. A first baffle is slidably disposed in the installation port. The sliding direction of the first baffle is the same as that of the auxiliary plate. The first baffle and the auxiliary plate are connected. The first baffle slides into the first baffle to seal the first inlet.

[0017] By adopting the above technical solution, when the auxiliary plate moves to the outside of the collection frame, it drives the first baffle to move into the first inlet. The first baffle seals the first inlet, reducing the phenomenon that guanidine hydrochloride enters the collection frame from the first inlet without being filtered during the filtration of guanidine hydrochloride, thereby improving the filtration effect of guanidine hydrochloride.

[0018] Optionally, the bottom side wall of the collection frame is provided with a collection groove communicating with the second socket. A collection plate is provided in the collection groove. The collection plate is connected to the auxiliary plate. The collection plate moves into the second socket to seal the second socket.

[0019] By adopting the above technical solution, when the auxiliary plate moves, it drives the collection plate to move, so that the collection plate moves from the collection tank to the second inlet and seals the second inlet, reducing the leakage of guanidine hydrochloride from the second inlet during guanidine hydrochloride filtration.

[0020] Optionally, a switch assembly is provided inside the auxiliary plate. The switch assembly includes a switch plate, a switch gear, and a switch element. The switch plate is slidably disposed in the auxiliary plate in a vertical direction. The auxiliary tube is disposed near the first socket. The switch plate abuts against the inner wall of the auxiliary plate. An opening is provided on the side of the auxiliary plate. A toothed groove is provided on the switch plate along its sliding direction. The switch element is disposed on the auxiliary plate. The switch gear is disposed at the output end of the switch element. The switch gear meshes with the opening and the toothed groove.

[0021] By adopting the above technical solution, after the auxiliary plate moves to the bottom of the filter bucket, the switching component drives the switching plate to move, so that the switching plate moves to below the port of the auxiliary pipe, connecting the inside of the auxiliary plate and the auxiliary pipe, so that impurities can enter the auxiliary bucket through the auxiliary plate and the auxiliary pipe for collection.

[0022] Optionally, the bottom of the collection frame is inclined towards the ground on the side near the collection tube.

[0023] By adopting the above technical solution, the bottom of the collection frame is tilted so that after the guanidine hydrochloride filter enters the collection frame, it enters the collection tube, thereby improving the collection efficiency of guanidine hydrochloride.

[0024] Optionally, both the collection trough and the collection plate are inclined, and the end of the collection plate near the auxiliary plate is slidably disposed on the auxiliary plate in the vertical direction.

[0025] By adopting the above technical solution, the end of the collecting plate and the side of the auxiliary plate are slidably connected. When the auxiliary plate moves the collecting plate, the collecting plate moves relative to the auxiliary plate, so as to adjust the position of the collecting plate and reduce the phenomenon of the auxiliary plate interfering with the movement of the collecting plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to clean impurities, the control components simultaneously move the mounting plate and the placement plate. While moving the cleaning brush to the opening of the filter barrel, the auxiliary plate is moved to the bottom of the filter barrel. The cleaning brush cleans the impurities and collects them into the auxiliary plate, so as to clean the impurities in the filter barrel. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a device for preparing guanidine hydrochloride. (Refer to...) Figure 1 and Figure 2 The guanidine hydrochloride preparation equipment includes a frame 1 and a filter tank 2 mounted on the frame 1. Figure 3 A filter hole 21 for filtering guanidine hydrochloride is provided at the bottom of the filter tank 2. A collection assembly 3 for collecting guanidine hydrochloride is also provided at the bottom of the filter tank 2. The collection assembly 3 includes a collection tank 31, a collection frame 32, and a collection tube 33. The collection tank 31 is located on one side of the frame 1, the collection frame 32 is located at the bottom of the filter tank 2, and the collection tube 33 is located between the collection frame 32 and the collection tank 31 to connect them. The collection frame 32 is positioned close to the filter tank 2, and the collection frame 32 communicates with the filter hole 21 at the bottom of the collection tank 31. The guanidine hydrochloride solution is poured into the collection tank 31, sieved through the filter hole 21, enters the collection frame 32, and is then collected into the collection tank 31 through the collection tube 33.

[0037] Reference Figure 3 and Figure 4A mounting plate 4 is provided on the top of the collection bucket 31, and a feed pipe 41 is provided on the mounting plate 4, passing through the mounting plate 4. The mounting plate 4 is slidably mounted on the filter bucket 2 in the horizontal direction, and a cleaning device 5 is provided on the mounting plate 4. The cleaning device 5 includes a pushing component 51, a rotating component 52, a mounting plate 53, and a cleaning brush 54. A partition plate 42 is provided at intervals on the side of the mounting plate 4 away from the filter bucket 2, and a cleaning port 43 is provided on the mounting plate 4 at a position corresponding to the partition plate 42. The cleaning port 43 is the same size as the opening of the filter bucket 2. The pushing component 51 is provided on the partition plate 42 and is a cylinder. The output end of the cylinder is positioned through the partition plate 42 and faces the filter bucket 2. The rotating component 52 can be a motor, and the motor is located at the output end of the cylinder. The rotation center of the mounting plate 53 is connected to the driving component. The cleaning brush 54 is provided on the side of the mounting plate 53 near the filter bucket 2 and is arranged on the mounting plate 53 along the diameter direction of the mounting plate 53. In the initial state, the mounting plate 53 is set inside the cleaning port 43. When it is necessary to clean the impurities adhering to the filter barrel 2, the mounting plate 4 is moved. The mounting plate 4 drives the feed pipe 41 to move to one side of the filter barrel 2, and the mounting plate 53 is moved to correspond with the filter barrel 2. Then, the cylinder drives the mounting plate 53 to move to the bottom of the filter barrel 2 through the rotating part 52. At the same time, the cleaning brush 54 abuts against the bottom of the filter barrel 2. The rotating part 52 drives the mounting plate 53 to rotate, which in turn drives the cleaning brush 54 to rotate, cleaning the impurities at the bottom of the filter barrel 2.

[0038] Reference Figure 4 and Figure 5 A placement plate 6 is provided on the frame 1, and the placement plate 6 is slidably disposed on the frame 1 in the direction toward the filter bucket 2. An auxiliary device 7 is provided on the placement plate 6. The auxiliary device 7 includes an auxiliary bucket 71, an auxiliary pipe 72, and an auxiliary plate 73. The auxiliary bucket 71 is disposed on the placement plate 6, the auxiliary pipe 72 is disposed on the auxiliary bucket 71, and the auxiliary plate 73 and the auxiliary pipe 72 are connected to the ends opposite to the auxiliary bucket 71. The auxiliary plate 73 and the collection frame 32 are disposed on the same horizontal plane. A first inlet 22 is provided at the bottom of the filter bucket 2, and a second inlet 321 is provided on the collection frame 32. The first inlet 22 is arranged along the radial direction of the bottom of the filter bucket 2. The second inlet 321 is arranged in the same plane as the first inlet 22 and in the same vertical direction. The auxiliary plate 73 is slidably arranged in the first inlet 22 and the second inlet 321 in the horizontal direction. The auxiliary plate 73 has a hollow structure and an auxiliary opening is opened on the side near the first inlet 22. The interior of the auxiliary plate 73 is connected to the auxiliary tube 72. When it is necessary to clean impurities, the auxiliary plate 73 is slid into the first inlet 22. When the mounting plate 53 drives the cleaning brush 54 to rotate, the impurities are gradually pushed into the first inlet 22 and enter the auxiliary plate 73 through the first inlet 22, and then enter the auxiliary bucket 71 for collection.

[0039] Reference Figure 3 and Figure 4 The sliding direction of the auxiliary plate 73 is the same as that of the mounting plate 4. An intermediate rod 61 is provided between the placement plate 6 and the mounting plate 4 to connect them. A control component 62 is provided on the frame 1. The control component 62 can be a cylinder, and the output end of the cylinder is connected to the placement plate 6. The positions of the mounting plate 4 and the placement plate 6 can be adjusted simultaneously by the cylinder. While moving the cleaning brush 54 to the filter bucket 2, the auxiliary plate 73 is moved to the bottom of the filter bucket 2 to collect impurities.

[0040] Reference Figure 5 and Figure 6 To reduce the possibility of guanidine hydrochloride entering the collection frame 32 unfiltered through the first inlet 22 during guanidine hydrochloride filtration, an installation port 8 communicating with the first inlet 22 is provided on the bottom wall of the filter tank 2. The installation port 8 and the first inlet 22 are aligned on the same straight line. A first baffle 81 is slidably disposed within the installation port 8, with the sliding direction of the first baffle 81 being the same as that of the auxiliary plate 73, and one side of the first baffle 81 being connected to the auxiliary plate 73. When the auxiliary plate 73 moves to the outside of the collection frame 32, it moves the first baffle 81 into the first inlet 22, sealing the first inlet 22 and reducing the possibility of guanidine hydrochloride entering the collection frame 32 through the first inlet 22.

[0041] Reference Figure 6 and Figure 7A switch assembly 9 is provided inside the auxiliary plate 73. The switch assembly 9 includes a switch plate 91, a switch gear 92, and a switch element 93. The switch plate 91 is slidably disposed in the auxiliary plate 73 in the vertical direction. The auxiliary tube 72 is disposed near the first insertion port 22. The side of the switch plate 91 abuts against the inside of the auxiliary plate 73 to control the communication between the inside of the auxiliary plate 73 and the auxiliary tube 72. An opening communicating with the inside of the auxiliary plate 73 is opened on the side of the auxiliary plate 73. The switch element 93 can be configured as a motor. The motor is disposed outside the auxiliary plate 73. The switch gear 92 is disposed at the output end of the motor. A toothed groove 911 is provided on the switch plate 91 along its sliding direction. The switch gear 92 meshes with the toothed groove 911. In the initial state, the side of the switch plate 91 abuts against the end of the auxiliary tube 72, isolating the interior of the auxiliary plate 73 from the auxiliary tube 72. After the auxiliary plate 73 is fully moved into the first socket 22, the switch member 93 drives the switch plate 91 to move in a direction away from the first socket 22 until the switch plate 91 moves until its side and the end of the auxiliary tube 72 separate, that is, the side of the switch plate 91 facing away from the ground is flush with the side of the auxiliary tube 72 near the ground. At this time, impurities can enter the auxiliary plate 73 through the first socket 22, and then enter the auxiliary tube 72 through the auxiliary plate 73, reducing the phenomenon of some guanidine hydrochloride entering the auxiliary plate 73 before the auxiliary plate 73 is fully moved to the first socket 22. The side of the switch plate 91 facing away from the ground is set at an angle, and the lowest edge of this side is set close to the auxiliary tube 72. So that when the switch plate 91 moves to the auxiliary tube 72, impurities enter the auxiliary tube 72 through the angled surface.

[0042] Reference Figure 5 and Figure 6 To reduce the leakage of guanidine hydrochloride from the second inlet 321 to the outside of the collection frame 32, a collection groove 322 is provided in the side wall at the bottom of the collection frame 32. The collection groove 322 and the second inlet 321 are aligned on the same straight line and are connected. A collection plate 323 is provided in the collection groove 322 and is connected to an auxiliary plate 73. When the auxiliary plate 73 moves toward the outside of the second inlet 321, it moves the collection plate 323 into the second inlet 321, sealing the second inlet 321 and reducing the leakage of guanidine hydrochloride through the second inlet 321.

[0043] Reference Figure 6 and Figure 7The bottom of the collection frame 32, near the collection pipe 33, is inclined towards the ground to allow guanidine hydrochloride to enter the collection tank 31. Simultaneously, both the collection trough 322 and the collection plate 323 are inclined, with the end of the collection plate 323 near the auxiliary plate 73 sliding vertically on the auxiliary plate 73. That is, when the auxiliary plate 73 moves the collection plate 323, the end of the collection plate 323 slides vertically on the side of the auxiliary plate 73, reducing interference from the auxiliary plate 73 with the movement of the collection plate 323 and improving the stability of the collection plate 323 during movement.

[0044] The implementation principle of this application is as follows: After filtering guanidine hydrochloride, the control component 62 simultaneously moves the placement plate 6 and the mounting plate 4, moving the mounting plate 53 to the opening of the filter barrel 2. At the same time, the auxiliary plate 73 moves to the bottom of the filter barrel 2. Then, the switch component 93 moves the switch plate 91, making the auxiliary plate 73 and the auxiliary tube 72 connected. Then, the pusher 51 moves the cleaning brush 54 to the bottom of the filter barrel 2, sweeping the impurities into the auxiliary plate 73 and collecting them into the auxiliary barrel 71, so as to clean the impurities in the filter barrel 2.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
