Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery technology, and in particular to a filter device for formulation granule products. Background Technology

[0002] In the pharmaceutical industry, material screening and filtration are key processes in the production process. With the increasing demand for formulation granule products, the performance requirements for filtration equipment are also getting higher and higher. At present, the industry uses filter screens or single-stage filtration equipment for filtration operations. However, due to the high viscosity of some material extracts, the effect of atmospheric pressure filtration is poor and it will cause blockage, resulting in low production efficiency.

[0003] A search revealed Chinese Patent Publication No. CN210816152U, which discloses a pharmaceutical particle filtration device and its usage method. The device includes a filter body with a housing. Inside the housing is a vibrating filter screen. Pharmaceutical particles filtered by the vibrating filter screen are discharged through the outlet. The housing also contains a material loosening device. A guide chain passes through a first guide wheel and a second guide wheel, and reciprocates with the output shaft of a motor. A loosening vertical rod with multiple loosening teeth is mounted on the guide chain. The loosening vertical rod and loosening teeth are inserted into the pharmaceutical pile and reciprocate with the guide chain, effectively loosening the pharmaceutical particles while avoiding damage to them, thus improving the filtration efficiency of the pharmaceutical particle filtration device. The rotary vibrating screen is equipped with a blower and a vacuum cleaner inside the outer casing above the screen. The blower blows the medical dust away from the medical particles, and then the medical dust is sucked out of the casing by the vacuum cleaner, thereby improving the product quality of the medical particles. However, in actual use, the rotary vibrating screen achieves screening by rotation and vibration, which can cause the screen mesh to become clogged, resulting in low filtration efficiency and high energy consumption. Relying solely on a single rotary vibrating screen for filtration has limited precision and insufficient equipment stability, leading to shaking and vibration. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a filter device for formulated granule products, which aims to improve the problems of limited filtration accuracy, insufficient equipment stability, and shaking and vibration of existing rotary vibrating screens.

The sliding connection design between the support plate and the screen box, together with the rollers at the bottom of the screen box, allows the screen box to slide smoothly during vibration, reducing friction and improving vibration efficiency. The transmission plate in the vibration mechanism transmits the power of the drive mechanism to the screen box, causing the screen box to vibrate, thereby driving the internal material to be filtered. The shock absorption component can absorb the impact force generated by the screen box vibration, reducing the impact of vibration on the support and extending the service life of the device. The traction component further stabilizes the vibration trajectory of the screen box, ensuring the stability and directionality of the screen box vibration. The discharge component is responsible for discharging the filtered qualified particles from the screen box, realizing material collection. The internal state of the screen box can be observed through the manhole sight glass.

The outer walls of the two rotating shafts are rotatably connected to a clamping plate. The top of the outer walls of the two inclined mounting plates are provided with a slot. A cleaning component is provided inside the screen box.

[0010] Through the above technical solution: the inclined mounting plate provides a stable installation base for the filter screen, and its inclined design helps the material to flow and be screened better on the filter screen. The sliding connection between the filter screen and the inclined mounting plate, as well as the cooperation of the rotating shaft, the clamping plate and the clamping groove, make the filter screen easy to install and disassemble, easy to clean and replace, while ensuring that the filter screen is stable and does not loosen during operation, thus ensuring the filtration effect.

[0011] As a further description of the above technical solution:

[0012] The feeding mechanism includes a top plate, the bottom of which is slidably connected to the top of the screen box. The top of the top plate is connected to a feed inlet, and inserts are fixedly connected to the four corners of the bottom of the top plate. A dispersing plate is fixedly connected to the inner wall of the feed inlet.

[0013] The above technical solution facilitates the installation and disassembly of the feeding mechanism through the sliding connection between the top plate and the screen box, making equipment maintenance easier. The feed inlet provides a channel for materials to enter the screen box, while the insert ensures the accuracy of the feeding mechanism's position during installation, ensuring that materials can enter the screen box stably. The dispersion plate prevents material accumulation.

[0014] As a further description of the above technical solution:

[0015] The drive mechanism includes a servo motor, the bottom of which is fixedly connected to the top of the mounting bracket, and an eccentric wheel is fixedly connected to the output end of the servo motor.

[0016] Through the above technical solution: the servo motor serves as the power source, which can stably output power. The eccentric wheel converts the rotational motion of the servo motor into eccentric motion, providing a stable and continuous power input for the vibration mechanism and ensuring the vibration filtration operation of the screen box.

[0017] As a further description of the above technical solution:

[0018] The shock absorption assembly includes a fixing plate, the outer wall of which is fixedly connected to the inner wall of the bracket. Multiple shock absorption springs are fixedly connected to the right side of the outer wall of the fixing plate, and the right end of each of the multiple shock absorption springs is fixedly connected to the same rubber pad.

[0019] The above technical solution involves fixing the damping spring with a fixed plate. The damping spring and the rubber pad work together to absorb the impact force generated by the vibration of the screen box, reduce the damage of vibration to the support and other components, and ensure the stability of the device operation.

[0020] As a further description of the above technical solution:

[0021] The traction assembly includes a traction arm, the top of which is fixedly connected to the bottom of the top plate, and a sliding plate is fixedly connected to the outer wall of the screen box.

[0022] The above technical solution, through the cooperation of the traction arm and the sliding plate, can further stabilize the vibration trajectory of the screen box, prevent the screen box from shifting during vibration, and ensure the normal operation of the filtration work.

[0023] As a further description of the above technical solution:

[0024] The discharge assembly includes a discharge port connected to the bottom of the screen box, a collection bucket slidably connected to the top of the bottom plate, and a water outlet connected to the left side of the screen box.

[0025] The above technical solution provides a discharge channel for the filtered qualified particles, a collection bucket for collecting particles, and a sliding connection between the collection bucket and the bottom plate facilitates the cleaning and transfer of the collected particles, improving work efficiency. The water outlet discharges the water after cleaning.

[0026] As a further description of the above technical solution:

[0027] The cleaning assembly includes two partition plates, the outer walls of which are fixedly connected to the inner wall of the screen box. Multiple high-pressure nozzles are fixedly connected to the left side of the inner wall of the screen box, and water pipes are connected to the rear side of each of the multiple high-pressure nozzles. A drain valve is fixedly connected to the bottom of the inner wall of the screen box. A separation plate is fixedly connected to the outer wall of the left partition plate, and multiple convenient slag discharge port switches are rotatably connected to the inner wall of the right partition plate.

[0028] The above technical solution allows for the following: when dregs accumulate, the convenient dregs outlet switch can be opened and a water pipe connected. High-pressure spray nozzles can quickly disperse the dregs. Larger dregs in the mixture fall into the collection bucket through the outlet. After the water settles, it is discharged through the drain valve. There is no need to stop the machine to disassemble the filter screen, achieving online cleaning. This restores the filter screen to its permeability and allows for reuse, shortening maintenance time, improving cleaning efficiency, avoiding damage from manual disassembly, and ensuring continuous and efficient operation of the device. It is suitable for high-efficiency cleaning needs in production scenarios.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the power of the drive mechanism is transmitted to the vibration mechanism through the sliding cooperation between the eccentric wheel and the transmission plate, which drives the screen box to vibrate. The roller at the bottom of the screen box slides on the inner wall of the support plate to support and guide the vibration of the screen box. The shock-absorbing spring and rubber pad of the shock-absorbing component absorb the vibration impact force to achieve stable operation of the device. Through the cooperation between the traction component and the screen box slide plate, the vibration trajectory of the screen box is stabilized. Finally, the filtration mechanism in the screen box completes the particle size screening of the formula particles, and qualified particles fall into the collection bucket through the discharge port.

[0031] 2. In this utility model, the rotating shaft drives the card plate and the card slot to form a stable snap-fit ​​structure, so that the filter screen remains fixed when the screen box vibrates, and will not be displaced or loosened, effectively ensuring the filtration accuracy. The design of lifting the filter screen and rotating the rotating shaft in the opposite direction to disengage the card plate from the card slot makes the filter screen disassembly process simple and quick, and facilitates timely cleaning or replacement. The structure of setting the top plate that can be moved upward and disassembled from the bracket makes the operating space more open when installing and disassembling the filter screen, reducing the difficulty of operation and improving maintenance efficiency.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] See attached document Figure 2 Appendix Figure 3 and attached Figure 5This utility model provides an embodiment of a formula granule product filtration device, including a base plate 1.

A mounting frame 4 is fixedly connected to the top of the base plate 1, mounting the drive mechanism 5. A drive motor is located on the top of the mounting frame 4. The drive mechanism 5 provides power for the operation of the entire device and drives the screen box 7 to vibrate. The inner wall of the support 2 is fixedly connected to the support plate 6, which supports the screen box 7. The top of the support plate 6 is slidably connected to the screen box 7, which is the main component for material filtration. The screen box 7 is equipped with a vibration mechanism 8 on the outside of the screen box 7. The vibration mechanism 8 transmits the power of the drive mechanism 5 to the screen box 7. The screen box 7 is equipped with multiple filtration mechanisms 9 inside, which are used to screen qualified products. Two manhole sight glasses 10 are fixedly connected to the front side of the outer wall of the screen box 7 for observing the screening situation inside the screen box 7.

[0042] The vibration mechanism 8 includes a transmission plate 801. The left side of the outer wall of the transmission plate 801 is fixedly connected to the right side of the outer wall of the screen box 7, transmitting the power of the drive mechanism 5 to the screen box 7. Multiple rollers 802 are fixedly connected to the bottom of the screen box 7. The rollers 802 reduce the friction between the screen box 7 and the support plate 6 during vibration, making the vibration of the screen box 7 smoother. The outer walls of the multiple rollers 802 are slidably connected to the inner wall of the support plate 6, ensuring that the screen box 7 slides along the inner wall of the support plate 6 during vibration and preventing displacement. A shock-absorbing component 803 is provided on the left side of the screen box 7 to absorb the vibration. 7. To reduce the impact of vibration on the support 2, the shock absorption component 803 includes a fixing plate 8031. The fixing plate 8031 ​​is used to fix the shock absorption springs 8032 and provides an installation base for the shock absorption component 803. The outer wall of the fixing plate 8031 ​​is fixedly connected to the inner wall of the support 2 to ensure a stable connection between the shock absorption component 803 and the support 2. Multiple shock absorption springs 8032 are fixedly connected to the right side of the outer wall of the fixing plate 8031. The shock absorption springs 8032 absorb vibration energy through elastic deformation, thus playing a shock absorption role. The right ends of the multiple shock absorption springs 8032 are all fixedly connected to the same rubber. The rubber pad 8033 can buffer the impact force transmitted by the shock-absorbing spring 8032, further enhancing the shock absorption effect. Multiple traction components 804 are installed on the outside of the screen box 7. The traction components 804 are used to stabilize the vibration trajectory of the screen box 7, ensuring the stability and directionality of the vibration. The traction components 804 include traction arms 8041, which connect the top plate 301 and the screen box 7, transmitting traction force. The top of the traction arm 8041 is fixedly connected to the bottom of the top plate 301. A sliding plate 8042 is fixedly connected to the outer wall of the screen box 7. The sliding plate 8042 and the traction arm 8032... 041 is used to limit the vibration direction of the screen box 7 and ensure the accuracy of the vibration. The bottom of the screen box 7 is provided with a discharge component 805, which is used to discharge the filtered qualified particles from the screen box 7. The discharge component 805 includes a discharge port 8051, which is connected to the bottom of the screen box 7 to provide a discharge channel for qualified particles. A collection bucket 8052 is slidably connected to the top of the bottom plate 1. The collection bucket 8052 is used to collect the qualified particles discharged from the discharge port 8051 for subsequent processing. The left side of the screen box 7 is connected to a water outlet 8053 to discharge the water in the screen box 7.

[0043] Specifically, the material is poured into the top feed port 302 of the top plate 301 of the feeding mechanism 3 and falls into the screen box 7. Then, the servo motor 501 of the drive mechanism 5 starts, and the eccentric wheel 502 at its output end rotates. The outer wall of the eccentric wheel 502 slides on the inner wall of the transmission plate 801 of the vibration mechanism 8, driving the transmission plate 801 and causing the screen box 7 to vibrate. The roller 802 at the bottom of the screen box 7 slides and guides on the inner wall of the support plate 6. The fixing plate 8031 ​​of the left shock absorption component 803 is fixed to the inner wall of the bracket 2. The shock absorption spring 8032 and the rubber pad 8033 absorb the vibration impact. At the same time, the traction arm 8041 of the traction component 804 cooperates with the sliding plate 8042 on the outer wall of the screen box 7 to stabilize the vibration trajectory of the screen box 7. When the screen box 7 vibrates, the internal filtration mechanism 9 filters particles of different sizes. Qualified particles fall into the collection bucket 8052 through the discharge port 8051, while large particles are left in the screen box 7 for processing.

[0044] See attached document Figure 3 and attached Figure 5 The filter mechanism 9 includes two inclined mounting plates 901, which provide the mounting base and support structure for the filter screen 902, ensuring the stability of the filtration process. The outer walls of both inclined mounting plates 901 are fixedly connected to the inner wall of the screen box 7, achieving a stable connection between the inclined mounting plates 901 and the screen box 7, ensuring that they will not shift during operation. The same filter screen 902 is slidably connected to adjacent sides of the outer walls of the two inclined mounting plates 901, allowing the filter screen 902 to be easily installed and removed, facilitating replacement and cleaning. Two rotating shafts 90 are fixedly connected to the top of the filter screen 902. 3. The rotating shaft 903 provides rotational support for the clamping plate 904, enabling the clamping plate 904 to be snapped together with the inclined mounting plate 901. The outer walls of both rotating shafts 903 are rotatably connected to the clamping plate 904. The clamping plate 904, through rotation, cooperates with the inclined mounting plate 901 to fix the filter screen 902 and prevent the filter screen 902 from loosening during operation. The top of the outer wall of both inclined mounting plates 901 is provided with a slot 905. The slot 905 cooperates with the clamping plate 904 to form a snap-fit ​​structure, enabling the quick fixing and disassembly of the filter screen 902 to meet different filtration needs. The screen box 7 is equipped with a cleaning component 906.

[0045] Specifically, when installing the filter 902, insert the filter 902 into the predetermined position along the sliding rails on the adjacent side of the two inclined mounting plates 901. Rotate the locking plate 904 on the rotating shaft 903 and embed it into the locking groove 905 at the top of the inclined mounting plate 901 to form a stable locking structure. When disassembling, gently lift the filter 902 upwards, rotate the locking plate 904 in the opposite direction to disengage the locking plate 904 from the locking groove 905, and pull out the filter 902 along the sliding rail to complete the disassembly. During operation, ensure that the filter 902 is aligned with the sliding rail. After the locking plate 904 is embedded in the locking groove 905, check its firmness. Avoid using excessive force during disassembly to prevent damage to the locking structure.

[0046] See attached document Figure 1 Appendix Figure 2 and attached Figure 3 The feeding mechanism 3 includes a top plate 301, which supports the feed inlet 302 and provides an installation surface for the feeding mechanism 3, ensuring its stability. The bottom of the top plate 301 is slidably connected to the top of the screen box 7, enabling a detachable connection between the feeding mechanism 3 and the screen box 7, facilitating equipment installation, debugging, and maintenance. The top of the top plate 301 is connected to the feed inlet 302, which serves as a channel for material to enter the screen box 7, guiding the formulated granules smoothly into the filtration device. Inserts 303 are fixedly connected to the four corners at the bottom of the top plate 301, limiting the position of the feeding mechanism 3 at the top of the screen box 7 to ensure accurate feeding and prevent material spillage. A dispersing plate 304 is fixedly connected to the inner wall of the feed inlet 302, allowing material to pass through the feed inlet. The particles in the filter 302 are evenly dispersed on the filter screen 902 by the guiding action of the dispersion plate 304 to prevent accumulation. The drive mechanism 5 includes a servo motor 501, which serves as the power source for the drive mechanism 5 and provides stable power for the operation of the entire device. The bottom of the servo motor 501 is fixedly connected to the top of the mounting bracket 4 to achieve a stable installation of the servo motor 501 and ensure that it will not shake during operation. An eccentric wheel 502 is fixedly connected to the output end of the servo motor 501. The eccentric wheel 502 converts the rotational motion of the servo motor 501 into eccentric motion, providing power input to the vibration mechanism 8. The outer wall of the eccentric wheel 502 is slidably connected to the inner wall of the transmission plate 801 to transmit the eccentric motion to the vibration mechanism 8, driving the screen box 7 to vibrate.

[0047] Specifically, the feeding mechanism 3 is connected to the top of the screen box 7 via a sliding connection design of the top plate 301, enabling a detachable connection for easy maintenance. The feed inlet 302 guides the material to fall precisely into the screen box 7, and the insert cylinder 303 ensures a stable feeding position, prevents spillage, and improves feeding efficiency. The servo motor 501 of the drive mechanism 5 converts the rotational motion into eccentric motion through the eccentric wheel 502. The sliding connection between the eccentric wheel 502 and the inner wall of the transmission plate 801 enables power transmission, driving the screen box 7 to vibrate and providing the necessary power input for the filtration process, ensuring efficient operation of the device.

[0048] See attached document Figure 2 Appendix Figure 3 and attached Figure 5 The cleaning component 906 includes two partition plates 9061. The outer walls of the two partition plates 9061 are fixedly connected to the inner wall of the screen box 7. Multiple high-pressure nozzles 9062 are fixedly connected to the left side of the inner wall of the screen box 7. Water pipes 9063 are connected to the rear side of the multiple high-pressure nozzles 9062. A drain valve 9064 is fixedly connected to the bottom of the inner wall of the screen box 7. A separation plate 9065 is fixedly connected to the outer wall of the left partition plate 9061. Multiple convenient slag discharge port switches 9066 are rotatably connected to the inner wall of the right partition plate 9061.

[0049] Specifically, under normal conditions, the convenient slag discharge port switch 9066 is in the closed state. The partition plate 9061 divides the interior of the screen box 7 into a filtration zone and two side cleaning zones. The separation plate 9065 is inclined on the left partition plate 9061, guiding the filtered slag to gather at the right discharge port 8051. When the slag accumulation needs to be cleaned, the convenient slag discharge port switch 9066 is opened, and the water pipe 9063 is connected to an external drinking water source. The high-pressure nozzle 9062 sprays high-pressure water from the left side of the inner wall of the screen box 7 to wash the filter screen 902, the partition plate 9061, and the slag accumulation area from the side. The dispersed slag and water flow form a mixture, and the larger slag particles pass through the opening of the right partition plate 9061 with the water flow. The dregs fall into the collection bucket 8052 from the bottom outlet 8051 of the sieve box 7, achieving the initial discharge of the dregs. The water settles at the bottom of the sieve box 7 under the obstruction of the partition plate 9061 and is discharged from the equipment through the drain valve 9064 and the water outlet 8053. The filter holes on the surface of the partition plate 9065 intercept some larger impurities, avoiding blockage of the drainage channel and ensuring smooth discharge of the water. During the cleaning process, the sieve box 7 does not need to be stopped to disassemble the filter screen 902. The high-pressure water flow can directly wash the surface and gaps of the filter screen 902 to remove the adhering dregs, restore the permeability of the filter screen 902, and enable reuse. After cleaning, close the convenient dregs outlet switch 9066 and disconnect the water pipe 9063, and the device can quickly resume filtration operation.

[0050] Working principle: First, the material enters the device through the feeding mechanism 3. The material is poured in through the feed port 302 at the top of the top plate 301. Since the bottom of the top plate 301 is slidably connected to the top of the screen box 7, and the fixed inserts 303 at the four corners ensure a stable feeding position, the material falls evenly into the screen box 7 through the dispersing plate 304. Next, the drive mechanism 5 starts, and the servo motor 501 starts working. The eccentric wheel 502 at its output end rotates accordingly. The outer wall of the eccentric wheel 502 slides on the inner wall of the transmission plate 801, providing power to the vibration mechanism 8. The left side of the outer wall of the transmission plate 801 is fixedly connected to the right side of the outer wall of the screen box 7. The rotation of the eccentric wheel 502 drives the transmission plate 801, thereby causing the screen box 7 to vibrate. Multiple rollers 802 fixed at the bottom of the screen box 7 slide on the inner wall of the support plate 6, providing support and guidance for the vibration of the screen box 7. At the same time, the left side of the screen box 7... The shock absorption component 803 plays a role. The fixing plate 8031 ​​is fixed to the inner wall of the support 2. Multiple shock absorption springs 8032 and rubber pads 8033 on it can absorb the impact force generated by the vibration of the screen box 7, reduce the impact on the support 2, and ensure the stable operation of the device. In addition, the top of the traction arm 8041 of the traction component 804 is fixed to the bottom of the top plate 301 and cooperates with the sliding plate 8042 on the outer wall of the screen box 7 to further stabilize the vibration trajectory of the screen box 7. During the vibration of the screen box 7, multiple internal filtration mechanisms 9 filter the material. Different specifications of filter screens 902 screen out formula particles of different particle sizes. Particles that meet the requirements pass through the screen holes and are discharged through the discharge port 8051 at the bottom of the screen box 7, falling into the collection bucket 8052 slidably connected to the top of the bottom plate 1 for collection. Large particles that do not meet the requirements remain in the screen box 7 for subsequent processing.

[0051] Furthermore, when installing the filter screen 902, firstly, slide the filter screen 902 along the adjacent side of the two inclined mounting plates 901 until it reaches the predetermined position. Then, rotate the locking plate 904 on the rotating shaft 903 to insert the locking plate 904 into the locking groove 905 opened at the top of the outer wall of the inclined mounting plate 901. At this time, the locking plate 904 and the locking groove 905 cooperate with each other to form a stable snap-fit ​​structure, firmly fixing the filter screen 902 between the two inclined mounting plates 901, ensuring that the filter screen 902 is securely fixed between the two inclined mounting plates 901 during the filtration operation when the screen box 7 vibrates. The filter screen 902 will not shift or loosen, ensuring the stability and effectiveness of the filtration operation. When it is necessary to disassemble the filter screen 902 for cleaning or replacement, simply lift the filter screen 902 and rotate the retaining plate 904 in the opposite direction to disengage the retaining plate 904 from the retaining groove 905. After releasing the snap connection between the retaining plate 904 and the retaining groove 905, the filter screen 902 can be easily pulled out along the sliding track of the inclined mounting plate 901. When installing and disassembling the filter screen 902, the top plate 301 must be moved up in advance and removed from the bracket 2.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
