The output shaft of the motor 21 may be connected to the exciter 22, for example, by a flexible coupling 23. The exciter 22 may include an eccentric, and the exciter 22 excites vibration by rotation of the eccentric. The vibration pattern of the vibration mechanism 2 may be elliptical or circular, and an axis perpendicular to the vibration locus of the vibration mechanism 2 and an output shaft of the motor 21 are parallel.

The weight 4 may be connected to the exciter 22, the weight 4 and the grinding cylinder 1 may be located on opposite sides of the exciter 22, and the weight 4 may balance the mass of the components on both sides of the exciter 22. In fig. 1, the grinding cylinder 1 is positioned on the left side of the exciter 22, and the weight 4 is positioned on the right side of the exciter 22.

The mass of the counterweight 4 may be similar to the vibration mass of the grinding drum 1, the vibration mass of the grinding drum 1 including the mass of the grinding drum, the mass of the material to be ground and the mass of grinding media described later, for example, the mass of the counterweight 4 may differ from the vibration mass of the grinding drum 1 by less than 20%.

The vibration exciter 22 may be connected to the supporting point through the spring 3, one end of the spring 3 may be connected to the supporting point, and the other end of the spring 3 may be connected to the vibration exciter 22 and/or the weight 4. The support points may be located on the base 101 of the base plate 100 or on the base plate 100. The spring 3 may be a coil spring, a leaf spring, or the like, and the spring 3 may be a compression spring.

In the axial direction of the grinding cylinder 1, the main shaft of the vibration exciter 22 is located within the axial projection range of the grinding cylinder 1.

The grinding cylinder 1 may be connected to the exciter 22 by a connecting member 11, and the connecting member 11 may be located at an end portion of the exciter 22 in an axial direction, and the exciter 22 and the grinding cylinder 1 may be coaxial in a central axis. The partition 5 may be provided with a through hole, and the connection member 11 may pass through the through hole of the partition 5. When grinding is carried out, the grinding cylinder 1 is closed, so that air can be prevented from contacting materials in the grinding cylinder, and the probability of oxidizing the materials is reduced.

The grinding cylinder 1 and the vibrating mechanism 2 are separated by a partition 5, one side (left side in fig. 1) of the partition 5 is a clean zone S1, and the other side (right side in fig. 1) of the partition 5 is a mechanical zone S2. The grinding cylinder 1 is positioned in the clean area S1, and the vibration mechanism 2, the spring 3 and the counterweight part 4 are positioned in the mechanical area S2. The partition 5 may extend in a vertical direction, and in a use place, the partition 5 may extend from the floor 100 to the ceiling 200 of the space.

In other possible embodiments, the components located in the clean zone S1 (including the grinding drum 1) and/or the components located in the machine zone S2 (including the vibration mechanism 2, the springs 3 and the counterweight 4) may also be enclosed by a cover, a portion of the wall of which corresponds to the partition 5.

In other possible embodiments, the seal may comprise a balloon, the balloon may be annular, and the connector may pass through the hollow portion of the balloon.

The grinding drum 1 can be rotated about its own axis so as to switch between a grinding state and a discharge state, for example the grinding drum 1 can be rotated 180 degrees. In the grinding state, as shown in fig. 2A, the grinding cylinder 1 is located below the cartridge 6; in the discharge state, as shown in fig. 2B, the grinding cylinder 1 can be rotated 180 degrees, and the grinding cylinder 1 is located above the cartridge 6.

In one possible embodiment, the grinding cylinder 1 may be connected to a sleeve, which is fitted over the connection piece, and which may be located inside the housing of the exciter 22, and which is rotatably connected to the housing of the exciter 22. The sleeve can be connected with a turnover motor through a transmission mechanism, and the turnover motor drives the sleeve to enable the grinding cylinder 1 to rotate, so that the grinding state and the discharging state can be switched. The grinding cylinder 1 is connected to the vibration exciter through a sleeve, and the interior of the grinding cylinder 1 is free of a bearing, so that the grinding cylinder 1 can be heated, the lubricating oil in the bearing does not need to flow out in the environment of high-temperature steam, and the environment of cleaning in place (CIP, cleaning in place) and sterilizing in place (SIP, sanitize in place) which are described later can be adapted, and the bearing is a rolling bearing in the narrow concept. The sleeve may also be replaced with a flange or other connection.

It will be appreciated that the turning motor is not necessary and that on a miniaturized device, the grinding drum is smaller and lighter and the turning of the drum can be accomplished manually.

Under the state that vibration mechanism 2 shut down, can rotate grinding section of thick bamboo 1 to the discharge state, be favorable to the material to concentrate in the bottom of magazine, can discharge fast, clear up grinding section of thick bamboo fast and easily discharge thoroughly through the rotation of grinding section of thick bamboo 1.

The grinding cylinder 1 is internally provided with a grinding medium which can be rod-shaped, and materials can be impacted and ground with the grinding medium in the grinding process.

The diameter and height of the rod-shaped grinding media may be the same, the diameter of the rod-shaped grinding media may be 8mm to 31mm, and further optimized diameters may be 9 to 16mm, 13 to 22mm, 17 to 26mm, or 21 to 31mm.

The length of the other rod-shaped grinding media may be greater than the diameter, the diameter of the rod-shaped grinding media may be 8mm to 38mm, and further optimized diameters may be 9 to 16mm, 13 to 22mm, 17 to 26mm, or 21 to 31mm.

Further, the Rockwell hardness of the grinding medium in contact with the material and the inner container of the grinding cylinder 1 is not lower than 31HRC, the optimized hardness is not lower than 45HRC, the optimized hardness is not lower than 50HRC, the optimized hardness is not lower than 60HRC, and the optimized hardness is not lower than 87HRC. The grinding medium and the inner container of the grinding cylinder 1 can be made of materials including but not limited to ceramic materials, hard alloy materials, wear-resistant steel materials and the like, and the materials are difficult to generate scraps after friction, so that the scraps generated by friction can be prevented from being mixed into materials.

In the case of wet grinding, the materials of the grinding media and the inner liner of the grinding drum 1 include, but are not limited to, alumina, zirconia, aluminum nitride, cemented carbide, etc., and include, but are not limited to, high hardness materials such as zirconia, toughened zirconia, yttria Toughened Zirconia (TZP), alumina toughened zirconia, silicon nitride, silicon carbide boron carbide composite ceramics, aluminum nitride, cemented carbide, etc.

The cartridge 6 is connected to the grinding drum 1, and the cartridge 6 can be connected to a feed conduit 61 and a discharge conduit 62. Because the grinding cylinder 1 is suspended on one side of the partition plate 5, a pipeline is easy to be arranged in the material box 6, and the pipeline is not easy to wind and interfere with other components when the grinding state and the discharging state of the grinding cylinder 1 are switched.

After the clean grinding equipment finishes grinding, materials (tails) are still stored in the grinding cylinder 1 and/or the material box 6, and the emptying of the materials can be accelerated by properly prolonging the discharging time. The discharge process may be by positive pressure, negative pressure, or a combination of both. The mill cylinder 1 and/or the tailings in the cartridge 6 can then be flushed, carried, and discharged with solvent through the tubing connecting the cartridge 6. The process can help the grinding medium to move through the combination of the vibration mechanism 2 and the overturning of the grinding cylinder 1, and the solvent is well eluted between the grinding medium and between the grinding medium and the cylinder wall, so that the tailing stripping, scouring and discharging the grinding cylinder 1 along with the solvent are realized.

In order to avoid or reduce wear between the grinding media and the media on the grinding drum 1, cleaning is preferably effected in such a way that the grinding drum 1 is turned over. The overturning angle can be not less than 180 degrees, and the reciprocating overturning operation can avoid the winding of the pipeline. Such solvents include, but are not limited to, water, ethanol, solvent oils, ethyl acetate, propanol, oils and the like.

The cleaning process may also be used in accordance with conventional cleaning patterns of cleaning in place (CIP, cleaning in place), including but not limited to hot water, acid water, alkaline water, cold water in sequence.

After the cleaning (sweeping) is completed, in-situ sterilization (SIP, sanitize in place) may be optionally performed, and steam may be introduced into the grinding drum 1 from the feed pipe 61 or a dedicated pipe, and the steam temperature and the amount may satisfy sterilization conditions. The vacuum can be pumped first before the steam is introduced, so that the steam heating sterilization effect is improved. The temperature of steam sterilization can also be increased by water jacket heating.

In the sterilization process, a mode of overturning the grinding drum 1 can be adopted to improve the uniform sterilization state, and the specific sterilization temperature and time are determined based on actual production verification.

Further, if the inside of the grinding cylinder 1 is required to be dried, a mode including but not limited to hot air drying, water jacket heating of the grinding cylinder, and vacuumizing can be adopted, and the sequence and the combination can be adopted. The water can be removed by heating before drying, for example, by heating with a water jacket, and the heating mode can be hot water, steam or heat conducting oil. The grinding cylinder 1 and the grinding medium can also be heated, and can be realized by adopting a mode of vacuumizing and/or introducing hot air. When the temperature of the grinding drum 1 and the grinding medium is higher than the evaporation temperature of water corresponding to the vacuum degree, the grinding drum can be dried quickly.

Under the condition that the power frequency is 50Hz, the vibration frequency of the grinding cylinder 1 can be 8-50 Hz, the optimized frequency is 10-30 Hz, the optimized frequency is 12-26 Hz, and the optimized frequency is 12-13 Hz, 15-17 Hz or 23-26 Hz. In another example, the vibration frequency of the grinding drum 1 can be 10-31 Hz, preferably 12-15 Hz, 16-20 Hz or 24-29 Hz, with a power frequency of 50 Hz. The amplitude (single amplitude, i.e. the vibration radius) of the grinding drum 1 can be 2-9 mm, optimally 3-5 mm, 5-8 mm or 4-6 mm. The vibration mode of the grinding cylinder 1 may be circular vibration or elliptical vibration.

Preferably, the vibration frequency of the grinding cylinder 1 can be 8Hz to 50Hz, the single amplitude is 2mm to 9mm, and the vibration acceleration is 2g to 10g.

When the cleaning grinding equipment is used for crushing fibrous materials, the materials are subjected to strong compression tearing action force, so that the tissue structure and the fibers are easily damaged, moisture (including crystal water), oil content, volatile matters, air and the like in the tissue structure are extruded, the probability of being oxidized is reduced, the void ratio in the tissue structure is reduced, and the compactness of the materials is increased.

Because substances in the tissue structure are extruded and adsorbed on the surfaces of the tissue fragments, the viscosity of the particles is increased, the particles are continuously kneaded and torn under the strong compression tearing action force, and the substances adsorbed on the surfaces of the tissue fragments migrate along with the substances, so that oily components and aqueous components form an emulsifying combination under the action of a biological surfactant (generally, the biological tissues contain substances with surface activity such as saponin, protein and the like), and the emulsifying combination is called solid emulsification.

At the same time of the compression tearing action, as the tissue structure is continuously destroyed and thinned in the crushing process, under the actions of compression, kneading and tearing, the thinned fragments of different tissue structures continuously form a new combination, namely 'precise compounding', through the viscosity action of migration substances in the tissues.

The fibrous material comprises plant medicine materials and animal medicine materials in traditional Chinese medicine, such as rhizome and leaf of plant, zaocys, etc. When the fibrous materials are ground and crushed, the materials are subjected to strong compression tearing acting force, and the tissue structure and fibers are easily damaged, so that moisture (including crystal water), oil content, volatile components and air in the tissue structure are extruded (the probability of being oxidized is reduced), the void ratio in the tissue is reduced, and the compactness of the materials is increased.

The pulverizing and grinding mechanism of the cleaning and grinding apparatus of the present application is described below.

The force mode of pulverization can be classified into non-compression pulverization and compression pulverization.

The instantaneous crushing force applied to the material by non-compressive crushing is unidirectional. According to the momentum theorem formula fΔt=mΔv, to achieve a sufficient impulse, the mass is equally important in addition to the amount of change in velocity. Taking jet milling as an example, the mass of the material is too small, the impact energy generated is extremely limited, and the milling effect is poor. Plant fibers in traditional Chinese medicinal materials (or decoction pieces) mainly containing plants are taken as an elastomer, material collision or impact generated by high-speed airflow is easy to generate rebound of particles under high-speed rotation, energy of the particles is reflected in a high-speed motion mode, and the energy is difficult to be converted into surface energy after particle refinement, so that the crushing efficiency is low. In rotor crushing, friction between materials and the rotor of crushing equipment is poor due to the fact that plant fibers are poor in heat conductivity, low in heat capacity and large in friction force, and the equipment is too small in cooling area, so that non-contact cooling is achieved, and the temperature rise of the materials is too high.

Compression crushing is to crush the material under two-way force. This approach is more effective for plant fibers having a low specific gravity, softness, toughness and yielding.

The utility model provides a clean grinding equipment can apply effort to chinese-medicinal material or decoction piece raw materials with shearing compression crushing mode, and chinese-medicinal material or decoction piece raw materials receive acceleration impact force P and shearing force L's combined action to by the compression tearing breakage under the effect of two-way complex force, the size of this crushing effort does not receive the influence of material quality. When the fibrous material is crushed in the mode, the tissue structure and the fibers are easily damaged due to the strong compression tearing acting force of the material. Under the action of external exciting force, the grinding medium makes a throwing motion which is dispersed and polymerized. The grinding medium makes the same-direction rotation movement, and the grinding medium group integrally makes revolution movement. The grinding media of the inner layer and the outer layer are continuously exchanged in position, and materials are continuously impacted, extruded and sheared between every two grinding media, so that the materials are crushed and sheared. The particles are broken up from large to small. In the crushing process, larger particles are stressed and crushed first. In the momentum calculation formula fΔt=mΔv to which the plant fiber is subjected, m corresponds to the weight of the grinding medium, Δv and Δt are related to the vibration frequency, and F corresponds to the resultant force of the positive pressure and the shearing force of the grinding medium.

The clean-up grinding apparatus can adjust the probability of stress times (including product uniformity) by adjusting the macroscopic stress time (grinding time). The cleaning and polishing equipment can adjust the microscopic stress state by adjusting the macroscopic stress, namely, the impact speed of the polishing medium by adjusting the vibration acceleration and the vibration frequency of the polishing cylinder 1.

The clean grinding equipment can enable materials to be in a fluidized motion state in the grinding cylinder 1, and larger particles can be stressed first and crushed preferentially in the motion state, so that high-efficiency grinding is achieved. The particles of the plant cell population, whether particles of large cells or particles of small cell population, are extruded and the chances of impact are equal to each other with a large probability as long as the overall size is similar. That is, during the pulverization of the plant fiber, the probability of pulverization is the same as long as the overall size is similar, regardless of the large cell population or the small cell population.

Following the innovative guidelines of traditional Chinese medicine, a single Chinese medicine is a small compound, and the components contained in plant tissues in different growth periods are different. According to the technical scheme, the whole component can be free of slag in the crushing or grinding process, and the medicinal materials cannot be selectively crushed due to the characteristic difference of crushing difficulty. Therefore, in the production process of the invention, the medicine residues are not generated due to the grading of the granularity, only a small amount of material is lost due to the conditions of material residue and the like, and the lost material components are similar or identical to the finished product in principle, so that the component segregation caused by the medicine residues is avoided as much as possible.

Although the above-described pulverizing and grinding mechanism is exemplified by a drug, the cleaning and grinding apparatus of the present application is not limited to application in the pharmaceutical industry, and the cleaning and grinding apparatus can be widely used in the powder industry, for example, can be used for grinding electronic materials, pigments, adhesives, foods, chemical materials, metal materials, and the like.

As shown in fig. 3, the cartridge 6 and the coarse crushing device 7 are connected by a feed pipe 61, and the cartridge 6 and the vacuum suction device 8 are connected by a discharge pipe 62. In the grinding state, the cartridge 6 is located above the grinding drum 1, and the discharge conduit 62 may be located at the top of the cartridge 6. The blanking port of the vacuum suction device 8 may be connected to a receiving container 300 or to a material handling apparatus (e.g. a vibrating screen). The material box 6 can be cylindrical or cubic, which is beneficial for sucking the materials ground into powder into the material box 6.

As shown in fig. 3, when feeding the grinding cylinder 1, the cartridge 6 is located above the grinding cylinder 1, and the interface (i.e., the discharge interface) of the cartridge 6 with the discharge pipe 62 is located above the interface (i.e., the feed interface) of the cartridge 6 with the feed pipe 61. Optionally, the discharge port is located at the top or upper portion of the cartridge 6 and the feed port is located at the lower portion of the cartridge 6. Negative pressure is formed in the material box 6 under the action of the vacuum suction device 8, raw materials are fed into the material box 6 through the feeding pipeline 61 after being coarsely crushed by the coarse crushing device 7, and the maximum granularity of the coarsely crushed raw materials can be smaller than one third of the pipe diameter of the feeding pipeline 61. During grinding, the ground material easily flies into the cylindrical cartridge 6 and is sucked as a finished product into the collecting container 300 through the discharge pipe 62. The granularity and the productivity of the finished product can be controlled by adjusting the feeding amount, the grinding parameters, the size of the material box and the like.

The material receiving container 300 may be a bag, and a weighing device may be provided below the bag, and whether grinding is completed may be determined by weighing. The bag may be provided with a vent.

The cleaning grinding equipment of the utility model is used for probability grinding, the grinding effect is controlled by the grinding time, and the longer the grinding time is, the higher the probability of grinding large particles is. Batch grinding can be used when grinding small amounts of material, and the grinding drum 1 needs to be switched between a grinding state and a discharge state. At this time, the clean grinding equipment circulates in the feeding, grinding and discharging processes.

When grinding a large amount of materials, the materials which are not crushed in the probability crushing process can be continuously fed and continuously discharged, and the ground finished products have lighter mass and can be discharged from the top of the material box. At this time, the clean grinding device performs grinding and discharging while feeding.

This application may be referred to as fourth generation vibratory finishing techniques. The beneficial effects of the clean grinding equipment comprise the following items.

(1) The cleaning grinding device can realize continuous feeding and continuous discharging through the feeding pipeline 61 and the discharging pipeline 62, so that dust pollution can be avoided, and clean production can be realized. And the process of discharging and overturning is omitted, so that the production efficiency is improved, and the failure rate is reduced.

(2) The materials which are preferentially ground and crushed can be discharged through the suction material box and cannot be continuously ground to occupy resources, so that the grinding efficiency is improved.

(3) The discharge of larger particles when the particles are not ground is avoided, so that the particle size distribution of the finished product materials is uniform, and the subsequent screening process can be more efficient or can be directly omitted.

(second embodiment)

The cleaning polishing apparatus of the second embodiment of the present application has a similar structure to the cleaning polishing apparatus of the first embodiment, and the same reference numerals are used to designate the same or similar components, and the corresponding description is omitted.
