Description

Technical Field

[0001] The invention belongs to the technical field of pharmaceutical processing, and in particular relates to a cleaning device and a cleaning method for pharmaceutical production. Background Art

[0002] In the pharmaceutical industry, the cleaning process of medicinal materials is a key step to ensure the quality and safety of drugs. The cleaning of medicinal materials is mainly to remove various impurities such as soil, dust and microorganisms that may be attached to the medicinal materials during the collection, transportation and storage process. If these impurities are not removed, they will not only affect the safety and effectiveness of the drugs, but also pose a serious threat to the health of consumers.

[0003] Traditional medicinal material cleaning methods mostly rely on manual operations, which are not only inefficient, but also difficult to maintain the consistency and repeatability of cleaning. They are too dependent on manual labor and difficult to mass-produce, which is unacceptable in modern pharmaceutical production. As the pharmaceutical industry develops in the direction of automation and standardization, the requirements for medicinal material cleaning devices are also increasing. Especially when processing large quantities of medicinal materials, a device is needed to ensure the cleaning quality while completing the cleaning task quickly, efficiently and continuously, which is urgently needed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a cleaning device and a cleaning method for pharmaceutical production. The specific technical scheme is as follows:

[0005] The present invention provides a cleaning device for pharmaceutical production, comprising a bracket and a square box on the bracket, wherein the box is longitudinally divided into a first cleaning section, a second cleaning section, a third cleaning section and a fourth cleaning section, a total of four sections, wherein a U-shaped screen with uniform openings at the bottom is longitudinally suspended at the bottom of the second cleaning section and the fourth cleaning section, and a cleaning assembly is arranged on the box, wherein the cleaning assembly is composed of a pre-washing mechanism attached to the side of the box and a brushing mechanism longitudinally penetrated through the box, wherein the brushing mechanism comprises a rotating shaft longitudinally penetrated through the box, wherein a plurality of groups of stirring rods with nozzles are inserted and staggered in the circumferential direction on the outer circumferential surface of the rotating shaft, and three bucket-shaped flipping wings are uniformly and obliquely arranged on the corresponding shaft sections in the first cleaning section and the third cleaning section, respectively, and filters obliquely arranged and matched with the clearance of the outer circumferential surface of the flipping wings are respectively arranged below the filters, which can flip the medicinal materials forward during rotation, and a flexible sieve-washing ring matching with the clearance of the U-shaped screen is sleeved on the shaft section corresponding to the fourth cleaning section of the rotating shaft, and the conveying and discharging of the medicinal materials are completed by rotation;

[0006] The medicinal materials enter the first cleaning section from the pre-washing mechanism, and the processed medicinal materials fall into the oblique filter at the bottom. As the stirring rod sprays water, the floating soil on the surface of the medicinal materials is washed away, and the flipping wings rotate clockwise to scoop the medicinal materials and enter the next stage. In the second cleaning section, the liquid flow sprayed by the rotating stirring rod continuously flushes the medicinal materials, friction and flipping remove the mud, and the brushed and stirred medicinal materials roll to the next stage until the medicinal materials fall into the filter. In the third cleaning section, the flipping wings rotate again to scoop the medicinal materials and send them to the next stage. After reaching the fourth cleaning section, the screening and washing ring rotates clockwise to drive the medicinal materials to complete the discharge.

[0007] As a preferred technical solution of the present invention, the pre-wash mechanism includes a pre-wash support longitudinally attached to the outside of the box body and rolling wheels longitudinally staggered therein, an inclined spray head is provided above the rolling wheel, and a square feed port facing upward is provided at the end of the pre-wash support, and its tail is connected to the first cleaning section.

[0009] When the medicinal materials are transported to the U-shaped screen of the fourth cleaning section, the sieve-washing ring rotates counterclockwise, driving the Z-shaped shoveling surface to contact the U-shaped screen at the bottom and then perform a small range of extrusion and contraction movement along the axial direction, driving the accommodating cavity to rotate and deviate toward the axial direction, and rotating to shovel the medicinal materials accumulated on the U-shaped screen into the accommodating cavity. Subsequently, the Z-shaped shoveling surface rotates to separate from the U-shaped screen and is no longer under pressure. The spring resets and drives the accommodating cavity to vibrate, causing the medicinal materials in the accommodating cavity to roll with the rotation of the sieve-washing ring to the Z-shaped shoveling surface, and transport the medicinal materials to the discharge port to complete the discharge.

[0010] As a preferred technical solution of the present invention, the flip wing includes a flip beam inserted in the rotating shaft and a wing plate thereon, the flip beam is provided with a shovel surface and a baffle with multiple flip bars arranged transversely, and the ends of the wing plate, the flip bar and the baffle are all provided with inward bending and warping to prevent the shoveled medicinal materials from falling;

[0011] When the flapping wing rotates counterclockwise, the shovel surface rotates downward and scoops the medicinal materials accumulated on the filter screen to the curved depression formed by the wing plate and the flapping strip for transfer and drainage. Then, the flapping wing rotates and climbs to a high place, and the scooped medicinal materials slide down the slope formed by the flapping strip to the U-shaped screen, completing the drainage and transfer of the medicinal materials.

[0016] As a preferred technical solution of the present invention, the flapping wing is detachably connected to the rotating shaft.

[0017] As a preferred technical solution of the present invention, the inclination angle and installation height of the filter can be adjusted according to the rotation radius of the flap wing.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Embodiment 1

[0031] In order to solve the technical problems in the background technology, the following cleaning device and cleaning method for pharmaceutical production are provided:

[0032] Combination Figure 1-Figure 4As shown, a cleaning device for pharmaceutical production includes a bracket 1 and a square box 2 thereon, wherein the box 2 is longitudinally divided into four sections, namely, a first cleaning section 22, a second cleaning section 23, a third cleaning section 24, and a fourth cleaning section 25, wherein a U-shaped screen 231 with uniform openings at the bottom is longitudinally suspended at the bottom of the second cleaning section 23 and the fourth cleaning section 25, and a cleaning assembly 3 is arranged on the box 2, wherein the cleaning assembly 3 is composed of a pre-washing mechanism 31 attached to the side of the box 2 and a brushing mechanism 32 longitudinally penetrated through the box 2, wherein the brushing mechanism 32 includes a pre-washing mechanism 31 longitudinally penetrated through the box 2, the outer circumference of the rotating shaft 321 is staggered and inserted with multiple groups of stirring rods 322 with nozzles 3222, and three bucket-shaped flipping wings 323 are evenly and obliquely arranged on the corresponding shaft sections in the first cleaning section 22 and the third cleaning section 24, respectively, and the filter screens 221 that are obliquely mounted and match the gaps with the outer circumference of the flipping wings 323 are respectively provided below them, which can flip the medicinal materials forward during rotation, and the rotating shaft 321 is sleeved with a flexible sieve washing ring 324 that matches the gaps with the U-shaped screen 231 on the shaft section corresponding to the fourth cleaning section 25, and the conveying and discharging of the medicinal materials are completed by rotation;

[0033] The medicinal materials enter the first cleaning section 22 from the pre-washing mechanism 31, and the medicinal materials to be processed fall into the oblique filter 221 at the bottom. As the stirring rod 322 sprays water, the floating soil on the surface of the medicinal materials is washed away, and the flipping wings 323 rotate clockwise to scoop up the medicinal materials and enter the next stage. In the second cleaning section 23, the liquid flow sprayed by the rotating stirring rod 322 continuously flushes the medicinal materials, friction and flipping remove the mud, and the brushing and stirring of the medicinal materials rolls to the next stage until the medicinal materials fall into the filter 221. In the third cleaning section 24, the flipping wings 323 rotate again to scoop up the medicinal materials and send them to the next stage. After reaching the fourth cleaning section 25, the screening and washing ring 324 rotates clockwise to drive the medicinal materials to complete the discharge.

[0034] Through the above technical solution, firstly, the device ensures the cleaning effect of medicinal materials through a segmented cleaning process. From pre-washing to deep cleaning, each stage specifically removes different types of pollutants, such as surface floating soil and deep mud, which helps to improve the quality and safety of the final medicinal materials. Secondly, the device not only overcomes the drawbacks of over-reliance on manual labor, reduces the need for manual operation, and significantly improves production efficiency, but also can operate continuously, greatly improving the total processing volume per unit time, which is particularly important for large-scale production. In addition, the design of the device takes into account the protection of medicinal materials. Through the flipping of the flexible screening ring 324 and the bucket-shaped flip wing 323, the physical damage to the medicinal materials is reduced, the integrity of the medicinal materials is maintained as much as possible, and the effective extraction of its effective ingredients is guaranteed. This gentle and effective treatment method helps to maintain the original properties of the medicinal materials, thereby ensuring the maximization of the efficacy.

[0035] As a preferred embodiment, a transparent cover 4 is provided on the top of the box body 2 to observe and monitor the cleaning process.

[0036] As a preferred embodiment, the inclination angle and installation height of the filter screen 221 can be adjusted according to the rotation radius of the flap wing 323 .

[0037] Embodiment 2

[0038] like Figure 8 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0039] In this embodiment, the pre-wash mechanism 31 includes a pre-wash support 313 longitudinally attached to the outer side of the box body 2 and rolling wheels 312 longitudinally staggered therein, an inclined spray head 315 is provided above the rolling wheel 312, and a square feed port 311 facing upward is provided at the end of the pre-wash support 313, and its tail is connected to the first cleaning section 22.

[0040] Through the above technical solution, first of all, this structural design allows the medicinal materials to be effectively turned over and loosened by physical means before entering the cleaning box 2, so that it is easier to remove large particles of impurities and floating soil adhering to the surface. The design of the oblique spray head 315 above the rolling wheel 312 can ensure that the water flow evenly covers the surface of the medicinal materials, enhances the cleaning force, effectively removes more surface dirt and dust, and reduces the burden for subsequent deeper cleaning. In addition, the upward-facing square feed port 311 design not only facilitates the input of medicinal materials, but also effectively prevents the overflow of medicinal materials during the feeding process, thereby improving work efficiency and the utilization rate of raw materials.

[0041] Embodiment 3

[0042] like Figure 1-Figure 7 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0043] In this embodiment, the sieve-washing ring 324 comprises a hollow sieve-washing cylinder 3241 and a sieve-washing frame 3242 which is longitudinally staggered on its outer circumference. The sieve-washing frame 3242 is circumferentially provided with a Z-shaped scooping surface 3244 formed by a plurality of elastic sieve-washing belts 3243 arranged longitudinally, and an inverted trapezoidal accommodating cavity 3245 is bent and extended from the scooping surface 3244, and an axial spring 3246 is embedded at the joint where the sieve-washing frame 3242 is connected to the starting section of the scooping surface 3244;

[0044] When the medicinal materials are conveyed to the U-shaped screen 231 of the fourth cleaning section 25, the sieve ring 324 rotates counterclockwise, driving the Z-shaped scooping surface 3244 to contact the U-shaped screen 231 at the bottom and perform a small range of squeezing and contracting movement along the axial direction after being compressed, driving the accommodating cavity 3245 to rotate and deviate toward the axial direction, and rotating to scoop the medicinal materials accumulated on the U-shaped screen 231 into the accommodating cavity 3245, and then the Z-shaped scooping surface 3244 rotates to disengage from the U-shaped screen 231 and is no longer compressed, and the spring 3246 resets to drive the accommodating cavity 3245 to vibrate, causing the medicinal materials in the accommodating cavity 3245 to roll over to the Z-shaped scooping surface 3244 as the sieve ring 324 rotates, and the medicinal materials are conveyed to the discharge port 21 to complete the discharge.

[0045] The flip wing 323 includes a flip beam 3231 inserted into the rotating shaft 321 and a wing plate 3232 thereon. The flip beam 3231 is provided with a plurality of flip bars 3233 arranged transversely on the shoveling surface and a baffle 3234. The ends of the wing plate 3232, the flip bars 3233 and the baffle 3234 are all provided with inward bending and warping to prevent the shoveled medicinal materials from falling.

[0046] When the flip wing 323 rotates counterclockwise, the shovel surface rotates downward and scoops the medicinal materials accumulated on the filter screen 221 to the curved depression formed by the wing plate 3232 and the flip bar 3233 for transfer and drainage. Then the flip wing 323 rotates and climbs to a high place, and the scooped medicinal materials flow along the slope formed by the flip bar 3233. The fourth cleaning section 25 of the box body 2 is embedded with a downward slanting discharge port 21 on the side where the sieve and wash ring 324 rotates, so as to receive the medicinal materials transported by the sieve and wash ring 324.

[0047] The end of the stirring rod 322 is provided with a plurality of friction heads 3221 circumferentially so as to increase the friction force of stirring the medicinal materials.

[0048] The flap wing 323 is detachably connected to the rotating shaft 321 .

[0049] Through the above technical solution, firstly, the structure of the sieve-washing ring 324 plays a key role in the process of transferring and conveying medicinal materials. After the medicinal materials are conveyed to the U-shaped screen 231 of the fourth cleaning section 25, the sieve-washing ring 324 rotates counterclockwise, driving the Z-shaped scooping surface 3244 to contact and press the U-shaped screen 231, and then perform a small range of squeezing and contracting movement along the axial direction. This design can not only gently scoop the medicinal materials accumulated on the U-shaped screen 231, avoiding excessive squeezing force on the medicinal materials, but also makes the accommodating cavity 3245 rotate and deflect in the axial direction, so that the medicinal materials can enter the accommodating cavity 3245 more smoothly.

[0050] Secondly, the spring 3246 reset mechanism provides sufficient guarantee for the lossless transportation of medicinal materials. When the Z-shaped scooping surface 3244 is separated from the U-shaped screen 231, the spring 3246 resets and drives the accommodating chamber 3245 to vibrate, causing the medicinal materials in the accommodating chamber 3245 to rotate and roll to the Z-shaped scooping surface 3244 with the sieve washing ring 324, and finally transported to the discharge port 21. The gentle vibration and rolling movement in this process effectively prevents the damage of the medicinal materials caused by rapid movement, and ensures the integrity of the medicinal materials.

[0051] Then, the design of the flap wing 323 further ensures the lossless transportation of the medicinal materials. When the flap wing 323 rotates counterclockwise, the shovel surface rotates downward, gently scooping the medicinal materials accumulated on the filter screen 221, and transporting and draining them through the curved depression formed by the wing plate 3232 and the flap bar 3233. As the flap wing 323 continues to rotate and climb to a higher place, the medicinal materials are smoothly transported to the discharge port 21 along the ramp formed by the flap bar 3233, further ensuring the lossless transportation of the medicinal materials throughout the process.

[0052] In addition, the design of the stirring rod 322 also provides important support for the cleaning and transportation of medicinal materials. The multiple friction heads 3221 arranged circumferentially at the end of the stirring rod 322 fully stir the medicinal materials, so that the medicinal materials can be fully stirred and cleaned during the cleaning process, while avoiding excessive mechanical stress on the medicinal materials during the stirring process.

[0053] Finally, the flap wing 323 is designed to be detachably connected to the rotating shaft 321, which makes the maintenance and cleaning of the entire device more convenient, ensures the flexibility and convenience of the equipment in use, and facilitates subsequent maintenance and repair.

[0054] In summary, the device forms a highly coordinated linkage system through the organic combination of the sieve-washing ring 324, the spring 3246 reset mechanism, the flap wing 323 and the stirring rod 322, which effectively realizes the efficient cleaning and lossless transportation of medicinal materials. This design not only improves the operating efficiency of the equipment, but also ensures the quality and integrity of the medicinal materials during the processing, avoids the damage of the medicinal materials caused by uneven force during the stirring process, thereby improving the economic benefits and effectively reducing the damage rate.

[0055] Embodiment 4

[0056] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0057] In this embodiment, a plurality of inverted conical collecting pipes 26 are vertically arranged inside the box body 2, and an obliquely extending return water pipe 314 is arranged at the bottom of the pre-wash support 313, all of which are connected to the wastewater tank 11 cavity at the bottom of the box body 2 to prevent wastewater overflow and contamination of medicinal materials.

[0058] Through the above technical solution, the liquid collecting pipe 26 utilizes the natural drainage characteristics of the inverted cone to accelerate the collection and guidance of water flow, reducing the impact of water accumulation on medicinal materials, and the oblique extension structure of the return pipe 314 ensures that wastewater can be effectively collected and directed to appropriate treatment facilities, reducing environmental pollution while also avoiding secondary pollution of wastewater to medicinal materials.

[0059] The working principle and use process of the present invention:

[0060] When the present invention is implemented, first, the medicinal materials to be cleaned are put in through the feed port 311. After the feeding, the medicinal materials first contact the rolling wheels 312 in the pre-washing mechanism 31. When these wheels rotate and roll, they spray high-pressure water through the oblique spray heads 315 above them, effectively washing and removing the floating dust and impurities on the surface of the medicinal materials. Subsequently, the medicinal materials are rolled and transported to the filter screen 221 of the first cleaning section 22. After reaching the first cleaning section 22, the stirring rod 322 in the box body 2 rotates with the rotating shaft 321 and sprays water to further clean the medicinal materials. Then, the bucket-shaped flip wing 323 scoops up the medicinal materials clockwise with the rotating shaft 321 and pushes them to the second cleaning section 23. After reaching the second cleaning section 23, the rotating stirring rod 322 continues to spray the liquid flow, and removes the mud on the surface of the medicinal materials through physical friction with the friction head 3221 at the end, while stirring the medicinal materials to roll to the next stage. After the medicinal materials enter the third cleaning section 24, the flap wing 323 scoops the medicinal materials clockwise again to drain the water and send them to the fourth cleaning section 25. The sieve ring 324 rotates to drive the medicinal materials to complete the final conveying and draining of surface water. Finally, the medicinal materials are discharged smoothly through the downwardly inclined discharge port 21 of the box body 2, completing the entire cleaning process.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

4. A cleaning device for pharmaceutical production according to claim 3, characterized in that: A plurality of friction heads (3221) are arranged circumferentially on the end of the stirring rod (322) to increase the friction force of stirring the medicinal materials.

5. A cleaning device for pharmaceutical production according to claim 1, characterized in that: The flapping wing (323) is detachably connected to the rotating shaft (321).

6. A cleaning method, using a cleaning device for pharmaceutical production according to any one of claims 1 to 5, characterized in that: The medicinal materials to be cleaned are fed into the oblique feed port (311) provided at the head of the pre-cleaning mechanism, the rolling wheel (312) starts to rotate, and the oblique spray head (315) sprays high-pressure water to wash away the dust on the surface of the medicinal materials. The medicinal materials are rolled and transported to the filter screen (221) of the first cleaning section (22). The stirring rod (322) rotates and sprays water accordingly, and the flapping wings (323) rotate clockwise to scoop up the medicinal materials and enter the second cleaning section (23). At this time, the liquid flow sprayed by the rotating stirring rod (322) continuously washes the rolling medicinal materials, removes the mud of the medicinal materials by friction, and stirs the medicinal materials to roll to the next stage until the medicinal materials fall into the filter screen (221). In the third cleaning section (24), the flapping wings (323) rotate again to scoop up the medicinal materials and send them to the fourth cleaning section (25). In conjunction with the clockwise rotation of the sieve washing ring (324), the water on the surface of the medicinal materials is drained, and finally transported to the discharge port (21).
