Description

Technical Field

[0001] This utility model relates to the technical field of oral solution filtration equipment, and in particular to an oral solution filtration device. Background Technology

[0002] Oral solution filtration devices are pharmaceutical equipment used to remove impurities, particles, and microorganisms from oral solutions, ensuring the clarity and safety of the solution. They are key equipment in the purification process of oral preparations production. Widely used in the production of traditional Chinese medicine oral liquids and chemical drug solutions, they can effectively reduce the content of insoluble particles in the solution, meet the pharmacopoeia's clarity standards for oral preparations, and ensure medication safety.

[0003] Existing technologies, such as the utility model patent with publication number CN219646855U, disclose a precipitation and filtration device for the production of oral solutions. This patent employs a storage tank and a filter disposed within the storage tank. The storage tank has an inlet and an outlet, and the filter is located between the inlet and the outlet. The storage tank has a first annular groove with an upward opening, and the filter has a second annular groove with a downward opening. The first and second annular grooves are configured to cooperate. The patent also includes a sludge removal component disposed on the storage tank, which has a scraper rotatably disposed within the storage tank. The scraper abuts against the first filter screen of the filter. This invention solves the problem of long cleaning time and difficulty in cleaning the filtration device, which leads to reduced production efficiency.

[0004] Existing filtration devices for oral solution production, such as those mentioned above, use multiple sets of bolts to fix the upper end cap to the tank. Although the cleaning device can clean the filter inside the tank during equipment operation, after long-term use, the user still needs to disassemble the equipment to replace the filter. When disassembling the equipment, the user needs to use tools to remove the bolts that lock the upper end cap one by one. Due to the sealing requirements between the tank and the end cap, a large number of bolts are used for fixing, which takes a long time for the user to disassemble the equipment, thus encroaching on effective production time. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that due to the sealing requirements between the tank and the end cap, a large number of bolts are used for fixing, and the time spent by users when disassembling the equipment is long, which encroaches on effective production time. Therefore, an oral solution filtration device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oral solution filtration device, comprising a tank body, a tank lid, a filter, a motor, a rotating shaft, and a cleaning rack. The tank lid is installed on the upper surface of the tank body, and a filter is installed on the inner wall of the tank body. The filter can be made of commonly used oral solution filter material. The motor is fixedly connected to the upper surface of the tank lid, and a rotating shaft is fixedly connected to the surface of the motor drive shaft. A cleaning rack is fixedly connected to the surface of the rotating shaft. The cleaning rack contacts the inner wall of the filter, and a locking device is installed on the surface of the tank body.

[0007] The locking device includes a mounting bracket, which is fixedly connected to the outer arc surface of the can body. A constraint shaft is fixedly connected to the inner wall of the mounting bracket. A buckle for clamping the can lid is rotatably connected to the surface of the constraint shaft. An assembly cylinder is fixedly connected to the surface of the can body. A sealing block is threadedly connected to the lower part of the assembly cylinder. A spring is fixedly connected to the upper surface of the sealing block. A T-shaped connecting rod is slidably connected to the inner wall of the assembly cylinder. The spring abuts against the lower surface of the T-shaped connecting rod. A connecting frame is fixedly connected to the upper surface of the T-shaped connecting rod. A limiting ring for limiting the position of the buckle is fixedly connected to the upper surface of the connecting frame.

[0008] Preferably, a support foot is fixedly connected to the lower surface of the tank, a limit block is fixedly connected to the surface of the constraint shaft, the limit block is fan-shaped, and a locking sleeve is fixedly connected to the side surface of the buckle. The locking sleeve is fitted onto the surface of the limit block. By using the cooperation of the limit block and the locking sleeve, the maximum rotation angle of the buckle can be constrained to avoid excessive rotation of the buckle, which would increase the difficulty of subsequent locking.

[0009] Preferably, the inner wall of the assembly cylinder is provided with a groove, and a damping sleeve is fixedly connected to the inner wall of the groove. The damping sleeve is sleeved on the surface of the T-shaped connecting rod. The damping sleeve can increase the friction between the T-shaped connecting rod and the assembly cylinder, thereby reducing the interference of vibration during equipment cleaning on the spring and preventing the spring from becoming unbalanced and unable to properly lock the T-shaped connecting rod.

[0010] Preferably, the inner wall of the limiting ring is provided with a storage groove that matches the buckle, and a chamfer is provided above the storage groove. The position of the buckle can be constrained by the limiting ring in the locked state, and at the same time, it can be ensured that multiple buckles are simultaneously changed to a clamping state under the pressure of the limiting ring.

[0011] Preferably, a connecting rope is fixedly connected to the outer arc surface of the limiting ring, and the other end of the connecting rope is fixedly connected to the surface of the buckle. The connecting rope can be used to connect the limiting ring and the buckle. When the limiting ring is pressed down and completely disengaged from the buckle, the connecting rope is pulled and tightened by the limiting ring, and pulls the buckle, thereby causing the buckle to disengage from the clamping state.

[0012] Preferably, a pin is fixedly connected to the upper surface of the can body, a round hole adapted to the pin is opened on the edge of the can lid, a chamfer is provided on the edge of the can lid, and a "U" shaped groove adapted to the pin is opened on the surface of the buckle. The pin can be used to initially constrain the position of the can lid to ensure the stability of the can lid during the locking process.

[0013] Preferably, the mounting bracket is movably connected to the inner wall of the buckle, and the end of the mounting bracket away from the tank is arc-shaped. By cooperating with the constraint shaft, the rotation center of the buckle can be constrained to ensure that the buckle rotates in a specified direction.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a locking device, users can quickly disassemble the device, thereby reducing the time spent on removing bolts and the problem of taking up production time, improving the convenience and timeliness of equipment maintenance, and effectively ensuring production continuity.

[0025] Please see Figures 1-7 This utility model provides a technical solution: an oral solution filtration device, including a tank 1, a tank lid 2, a filter 3, a motor 4, a rotating shaft 5, and a cleaning rack 6. The tank lid 2 is installed on the upper surface of the tank 1, and the filter 3 is installed on the inner wall of the tank 1. The filter 3 can be made of commonly used oral solution filter materials. The motor 4 is fixedly connected to the upper surface of the tank lid 2. The rotating shaft 5 is fixedly connected to the surface of the drive shaft of the motor 4. The cleaning rack 6 is fixedly connected to the surface of the rotating shaft 5. The cleaning rack 6 is in contact with the inner wall of the filter 3. A locking device 8 is installed on the surface of the tank 1.

[0026] In this embodiment: the locking device 8 includes a mounting frame 81, which is fixedly connected to the outer arc surface of the tank body 1. A constraint shaft 82 is fixedly connected to the inner wall of the mounting frame 81. A buckle 83 for clamping the tank cover 2 is rotatably connected to the surface of the constraint shaft 82. An assembly cylinder 86 is fixedly connected to the surface of the tank body 1. A sealing block 87 is threadedly connected to the lower part of the assembly cylinder 86. A spring 88 is fixedly connected to the upper surface of the sealing block 87. A T-shaped connecting rod 89 is slidably connected to the inner wall of the assembly cylinder 86. The spring 88 abuts against the lower surface of the T-shaped connecting rod 89. A connecting frame 812 is fixedly connected to the upper surface of the T-shaped connecting rod 89. A limiting ring 813 for limiting the position of the buckle 83 is fixedly connected to the upper surface of the connecting frame 812.

[0027] Specifically, a support leg 7 is fixedly connected to the lower surface of the tank body 1, a limit block 84 is fixedly connected to the surface of the constraint shaft 82, the limit block 84 is fan-shaped, and a locking sleeve 85 is fixedly connected to the side surface of the buckle 83. The locking sleeve 85 is fitted onto the surface of the limit block 84. By using the cooperation of the limit block 84 and the locking sleeve 85, the maximum rotation angle of the buckle 83 can be constrained to avoid the buckle 83 from rotating excessively, which would increase the difficulty of locking later.

[0028] Specifically, the inner wall of the assembly cylinder 86 is provided with a groove 810, and a damping sleeve 811 is fixedly connected to the inner wall of the assembly cylinder 86 in the groove 810. The damping sleeve 811 is sleeved on the surface of the T-shaped connecting rod 89.

[0029] In this embodiment: the damping sleeve 811 can increase the friction between the T-shaped connecting rod 89 and the assembly cylinder 86, thereby reducing the interference of vibration during equipment cleaning on the spring 88, which would otherwise cause the spring 88 to become unbalanced and unable to properly lock the T-shaped connecting rod 89.

[0030] Specifically, the inner wall of the limiting ring 813 is provided with a storage groove 814 that is adapted to the buckle 83. The upper part of the storage groove 814 is provided with a chamfer. By using the limiting ring 813 in the locked state, the position of the buckle 83 can be constrained. At the same time, it can ensure that multiple buckles 83 are simultaneously changed to a clamping state under the pressure of the limiting ring 813.

[0031] Specifically, a connecting rope 815 is fixedly connected to the outer arc surface of the limiting ring 813, and the other end of the connecting rope 815 is fixedly connected to the surface of the buckle 83.

[0032] In this embodiment: the connecting rope 815 can connect the limiting ring 813 and the buckle 83. When the limiting ring 813 is pressed down and completely disengaged from the buckle 83, the connecting rope 815 is pulled and tightened by the limiting ring 813, and pulls the buckle 83, thereby causing the buckle 83 to disengage from the clamping state.

[0033] Specifically, a pin is fixedly connected to the upper surface of the can body 1, and a round hole adapted to the pin is opened on the edge of the can lid 2. The edge of the can lid 2 is chamfered, and a "U" shaped groove adapted to the pin is opened on the surface of the buckle 83. The pin can be used to initially constrain the position of the can lid 2 to ensure the stability of the can lid 2 during the locking process.

[0034] Specifically, the mounting bracket 81 is movably connected to the inner wall of the buckle 83, and the end of the mounting bracket 81 away from the tank body 1 is set in an arc shape.

[0035] In this embodiment, the rotation center of the buckle 83 can be constrained by the cooperation between the mounting bracket 81 and the constraint shaft 82 to ensure that the buckle 83 rotates in a specified direction.

[0036] Working principle: During processing, unfiltered oral solution is added to tank 1 through the inlet on the lid 2. The oral solution enters tank 1 and falls into the filter 3 inside the tank 1. The filter 3 filters out impurities in the oral solution through its own filtration effect. The filtered oral solution is discharged through the outlet at the bottom of tank 1 into a pipe connected to the outlet so that it can be sent to the next processing area. When the equipment needs to clean the filter 3, the motor 4 is connected to the power supply and the motor 4 switch is turned on. The motor 4 is powered on and drives the rotating shaft 5. The rotating shaft 5 drives the cleaning frame 6 to rotate and sweep the filter residue attached to the inside of the filter 3 to the center area of ​​the filter 3.

[0037] When the user needs to replace the filter 3, press down on the limiting ring 813. The limiting ring 813, together with the connecting bracket 812, squeezes the T-shaped connecting rod 89. The T-shaped connecting rod 89 presses the spring 88. The spring 88 deforms under force. When the limiting ring 813 is completely disengaged from the buckle 83, the limiting ring 813 tightens the connecting rope 815. At this time, continue to press down on the limiting ring 813. The limiting ring 813 will then work with the connecting rope 815 to pull the buckle 83. The buckle 83 is pulled and rotates out along the axis of the constraint shaft 82, losing its locking effect on the can cover 2. Then another operator can remove the can cover 2. After the can cover 2 is removed, the operator can remove the filter 3 installed in the can body 1.

[0038] When using the locking device 8 to lock the can lid 2, the user can replace the spring 88 with different specifications according to actual needs to ensure the stability of the locking device 8. When replacing the spring 88, rotate the sealing block 87, and the sealing block 87 will gradually be unscrewed from the assembly cylinder 86. After the sealing block 87 is removed, the spring 88 located in the assembly cylinder 86 will no longer be obstructed, and the operator can then take the spring 88 out of the assembly cylinder 86 and replace it. After the replacement is completed, the sealing block 87 can be tightened again. By setting the locking device 8, the user can quickly disassemble the device, thereby reducing the time spent on removing bolts and the problem of taking up production time, improving the convenience and timeliness of equipment maintenance, and effectively ensuring the continuity of production.

[0039] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
