Technical Field

[0001] This application belongs to the field of pharmaceutical intermediate production technology, and in particular relates to a three-necked flask cleaning device. Background Technology

[0002] The production process of pharmaceutical intermediates mainly involves reacting the raw materials through water bath heating, followed by separation and purification steps such as extraction and distillation. The primary container used for the water bath heating reaction is a three-necked flask to facilitate temperature monitoring, material feeding, and gas management.

[0003] Each time a three-necked flask is used, it needs to be cleaned. Currently, the main cleaning method is to manually scrub it with a brush. However, due to the structural characteristics of the three-necked flask, it is inconvenient, inefficient, and the cleaning effect is not good. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides a three-necked flask cleaning device, which can effectively improve the cleaning efficiency of three-necked flasks and has a better cleaning effect.

[0005] To achieve the above objectives, the present invention employs the following technology:

[0006] A three-necked flask cleaning apparatus, comprising:

[0007] The mounting platform is rectangular in shape, with a placement groove on its top surface facing downwards. The placement groove contains a mounting part for vertically placing a three-necked flask and for aligning the flask openings on both sides with the sides of the placement groove.

[0008] Two sets of guiding mechanisms are respectively set on the mounting platforms on both sides of the placement slot, and the guiding mechanisms are moved along the length of the mounting platforms;

[0009] Two first rotating shafts are respectively set on the corresponding guide mechanism. The first rotating shafts are respectively set toward the axis of the bottle mouth on both sides of the corresponding three-necked flask and are respectively movable along their own axis.

[0010] The second rotating shaft is located above the placement slot and is coaxial with the axis of the middle mouth of the three-necked flask. The second rotating shaft is hollow and moves along its own axis. An air bladder is provided at the lower end of the second rotating shaft.

[0011] The brushes are evenly distributed around the first and second rotating shafts and on the outer surface of the airbag;

[0012] A drive unit is used to drive the first and second rotating shafts to rotate about their own axis and move along their own axis.

[0013] An inflation / deflation device is used to inflate and deflate the airbag via a second rotating shaft.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Under the action of the first and second rotating shafts, and in conjunction with the drive unit, the interior of the three-necked flask can be cleaned more thoroughly, with a better cleaning effect and can effectively improve the cleaning efficiency of the three-necked flask.

[0016] 2. Under the action of the pressure rod and the cooperating rod, and through the cooperation between the guide plate and the mounting block, a linear mechanism can be used to realize the movement of the first rotating shaft and the second rotating shaft into the mouth of the three-necked flask at different angles, so that the cleaning device has a lower cost, a higher degree of automation, and further improves the cleaning efficiency.

Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0023] This application provides a three-necked flask cleaning device, such as... Figures 1-4 As shown, the device includes: mounting platform 1, guide mechanism 3, first rotating shaft 4, second rotating shaft 5, airbag 6, brush 7, drive unit 8, inflation / deflation device 9, etc.

[0024] Among them, such as Figures 1-3 As shown, the mounting platform 1 is rectangular in shape. A placement groove 11 is formed downward in the middle of the top surface of the mounting platform 1. A mounting part 12 is provided in the placement groove 11. The mounting part 12 includes a ball groove 15 formed at the bottom of the placement groove 11 and arc grooves 16 formed on both sides of the placement groove 11. The arc grooves 16 are connected to the top surface of the mounting platform 1. When the three-necked flask 2 is placed in the mounting platform, the ball groove 15 can fit against the bottom of the three-necked flask 2, and the two arc grooves 16 can fit against the outer sides of the bottle necks on both sides of the three-necked flask 2, thereby fixing the three-necked flask 2 in a vertical position. The axes of the three bottle necks are parallel to and perpendicular to the width direction of the mounting platform 1.

[0025] like Figures 1-3 As shown, two sets of guide mechanisms 3 are respectively mounted on the mounting platforms 1 on both sides of the placement groove 11. The guide mechanisms 3 are moved along the length of the mounting platform 1. Each guide mechanism 3 is provided with a first rotating shaft 4. The first rotating shaft 4 is respectively set toward the axis of the bottle mouth on both sides of the corresponding three-necked flask 2 and is moved along its own axis. When the guide mechanism 3 approaches the three-necked flask 2 at a predetermined distance, the axis of the first rotating shaft 4 is collinear with the axis of the corresponding bottle mouth on both sides of the three-necked flask 2.

[0026] like Figure 1 and Figure 2 As shown, the second rotating shaft 5 is positioned above the placement groove 11 and coaxially with the axis of the middle neck of the three-necked flask 2. The second rotating shaft 5 is hollow and moves along its own axis. The inflation / deflation port of the airbag 6 is connected to the lower end of the second rotating shaft 5. Brushes 7 are evenly distributed around the periphery of the first rotating shaft 4 and the second rotating shaft 5 and on the outer surface of the airbag 6. The driving unit 8 is used to drive the first rotating shaft 4 and the second rotating shaft 5 to rotate around their own axes and move along their own axes; the inflation / deflation device 9 is used to inflate and deflate the airbag 6 through the second rotating shaft 5.

[0027] In application, the two sets of guide mechanisms 3 are separated facing each other along the length of the mounting platform 1 to leave space for the three-necked flask 2 to be placed into the placement slot 11 from top to bottom; the three-necked flask 2 is placed vertically, with the ball groove 15 fitting against its bottom surface and the arc groove 16 fitting against the outer sides of its two bottle mouths; then the two sets of guide mechanisms 3 are moved closer to the three-necked flask 2 at a predetermined distance along the length of the mounting platform 1, at which point the axis of the first rotating shaft 4 is collinear with the axis of the corresponding bottle mouths on both sides of the three-necked flask 2; the drive unit 8 drives the first rotating shaft 4 into the bottle mouths on both sides, and at the same time drives the second rotating shaft 5 to descend along the axis so that the air bladder in the contracted state enters the interior of the three-necked flask 2. Correspondingly, the first rotating shaft 4 and the second rotating shaft 5... The length of the brush 7 is equal to the length of the bottle mouth to ensure thorough cleaning. The inflation / deflation device inflates the air bag 6, causing it to expand. The brush 7 on the outer surface of the air bag 6 actively abuts against the inner wall of the three-necked flask 2. The drive unit 8 drives the first rotating shaft 4 and the second rotating shaft 5 to rotate, causing the brush 7 to thoroughly scrub the body and inner wall of the three-necked flask 2. Correspondingly, during the brush 7 scrubbing process, water can be rinsed into the three-necked flask 2 to accelerate the cleaning efficiency. Under the action of the first rotating shaft 4 and the second rotating shaft 5, and in conjunction with the drive unit 8, the interior of the three-necked flask 2 can be thoroughly cleaned, resulting in a better cleaning effect and effectively improving the cleaning efficiency of the three-necked flask 2.

[0028] Specifically, such as Figures 1-3 As shown, the guiding mechanism 3 includes guide rods 31 mounted on mounting platforms 1 on both sides of the placement slot 11. The guide rods 31 are arranged in the length direction of the mounting platform 1. A movable plate 32 parallel to the top surface of the mounting platform 1 slides through the guide rods 31. A guide plate 33 is provided on the top surface of the movable plate 32. The guide plates 33 are respectively arranged in the direction of the axis of the bottle neck on both sides of the corresponding three-necked flask 2. A mounting block 34 is slidably fitted on the guide plate 33 along its own length direction for mounting the first rotating shaft 4. The guiding mechanism 3 also includes a locking unit 35 for fixing the movable plate 32.

[0029] like Figure 2 and Figure 4 As shown, a frame 13 is provided above the placement slot 11. It is rectangular and its bottom surface is parallel to the top surface of the mounting platform 1. The second rotating shaft 5 is vertically inserted through the upper and lower ends of the frame 13. Specifically, the second rotating shaft 5 and the upper and lower ends of the frame 13 can be connected by bearings to achieve stable rotation of the second rotating shaft 5. The frame 13 is moved along the axis of the middle mouth of the three-necked flask 2.

[0030] like Figure 2 and Figure 3As shown, a support plate 37 is vertically provided at the far end of the guide plate 33. A spring 38 is provided between the support plate 37 and the mounting block 34. One end of the spring 38 is connected to the support plate 37, and the other end is connected to the mounting block 34. The mounting block 34 has mating rods 36 on both sides facing the width direction of the mounting platform 1. The bottom surface of the frame 13 has pressure rods 14 on both sides facing the length direction of the mounting platform 1. When the spring 38 is in its natural state, the mating rods 36 are spaced at a preset distance from the axis of the second rotating shaft 5.

[0031] like Figures 2-4 As shown, the drive unit 8 includes a first motor 81 and a second motor 82. A mounting groove 39 is provided on the mounting block 34, oriented towards the length of the guide plate 33. The first motor 81 is fixedly mounted in the mounting groove 39, and its drive end is coaxially connected to the first rotating shaft 4. The second motor 81 is fixedly mounted on the top surface of the frame 13, and its drive end passes vertically through the top surface of the frame 13 and is coaxially connected to the driving gear 17. A driven gear 18, meshing with the driving gear 17, is coaxially fixedly mounted on the second rotating shaft 5. The drive unit 8 also includes a linear mechanism 83 located on one side of the mounting platform 1, with its drive end facing the height direction of the mounting platform 1 and connected to the frame 13. In this embodiment, the linear mechanism 83 is a linear lead screw.

[0032] In application, after the three-necked flask 2 is placed, the two moving plates 32 are brought together until the first rotating shaft 4 is coaxial with the axis of the corresponding bottle neck on both sides. The locking unit 35 fixes the position of the moving plates 32, and the spring 38 pulls the mounting block 34, so that the first rotating shaft 4 is located outside the bottle neck on both sides. The linear mechanism 83 drives the frame 13 to descend, which drives the second rotating shaft 5 to move down. The retracted airbag 6 enters the middle bottle neck. At this time, the pressure rod 14 abuts against the mating rod 36. The linear mechanism 83 continues to drive the frame 13 to descend, and the airbag 6 enters the interior of the three-necked flask 2. The brushes 7 distributed on the second rotating shaft 5 enter the middle bottle neck. At the same time, the downward pressure of the pressure rod 14 on the mating rod 36 can be decomposed into a component force along the length direction of the guide plate 33. This component force causes the mounting block 34 to move down along the length direction of the guide plate 33, and the spring 38 is stretched, so that the first rotating shaft 4 and the brushes 7 distributed on it enter the bottle neck on both sides simultaneously.

[0033] Under the action of the pressure rod 14 and the cooperating rod 36, and through the cooperation between the guide plate 33 and the mounting block 34, the downward movement of the frame 13 is converted into the movement of the mounting block 34 along the guide plate 33. A linear mechanism 83 can realize the movement of the first rotating shaft 4 and the second rotating shaft 5 into the mouth of the three-necked flask 2 at different angles, so that the cleaning device has a low cost, a high degree of automation, and further improves the cleaning efficiency.

[0034] Preferred, such as Figure 2 and Figure 3As shown, the locking unit 35 includes a pin hole 351 perpendicular to the movable plate 32, and a lock hole 352 perpendicularly opened on the top surface of the mounting platform 1. When the pin hole 351 and the lock hole 352 coincide, the axis of the first rotating shaft 4 is coaxial with the corresponding bottle openings on both sides. The pin hole 351 and the lock hole 352 are used to insert the pin 353. Through the cooperation of the pin hole 351, the lock hole 352 and the pin 353, the movable plate 32 can be effectively fixed, and the movable plate 32 can be quickly positioned so that the axis of the first rotating shaft 4 remains coaxial with the corresponding bottle openings on both sides.

[0035] Preferred, such as Figure 2 and Figure 4 As shown, the inflation / deflation device 9 includes an air pump 91 located on the top surface of the frame 13. A rotary joint 51 is provided at the upper end of the second rotating shaft 5. The rotary joint 51 and the air pump 91 are connected through an air pipe 92. With the rotary joint 51, the second rotating shaft 5 can rotate relative to the rotary joint 51, which can effectively avoid the problem of the air pipe 92 getting tangled due to the rotation of the second rotating shaft 5. Correspondingly, a bracket can be provided on the top surface of the frame 13 to fix the air pipe 92.

[0036] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
