Description

Quantitative mixing production line and production method for powder veterinary drugs

Technical Field

The invention relates to the field of veterinary drug production, in particular to a quantitative mixing production line and a production method for powder veterinary drugs.

Background

To animal remedy production, no matter be western medicine animal remedy or traditional chinese medicine animal remedy and mostly all be with the form of powder at the market selling, but to powder animal remedy in-process of production, mix the ratio with multiple material at jar internal needs, current production line adds multiple material in jar internal, then makes various materials carry out mix the ratio evenly through constantly stirring, after the misce bene carrying out the filling to the medicament can.

However, the method has the great disadvantages that whether the mixing proportion of various raw materials in the tank body is completely and uniformly mixed or not and whether the content of each component reaches the standard or not after mixing is unknown; moreover, once the raw materials added into the tank body are damped and agglomerated, the content of the mixture ratio of the components can be directly influenced, and the uniform degree of the mixture ratio of the materials can be influenced; when the raw materials are added into the tank body, once the raw materials arch up, bridge building and the like occur in the tank body, the conditions of uneven discharging flow and less or no discharging occur, so that the accuracy of the final component proportion of the veterinary drug powder in the production process is influenced; and when mixing the stirring raw materials, can't learn the internal humidity content of jar, if the humidity of raw materials is too big still can lead to the stirring in-process to appear the caking, mobility and the finished product quality of material when can influencing final filling.

For the powder stirring process, the best time point of uniform mixing is not accurately grasped, continuous stirring in the tank body is required according to the standard mixing time, the upper, middle and lower three points in the tank body are required to be taken for intermediate detection of a semi-finished product for the determination of the standard time, and the process of determining whether to continue mixing is repeated until the three points reach the qualified standard range. And the standard time in the process of stirring the powder material every time is mostly 25-40 minutes, the mixing and stirring time is longer, if the volume of the mixing tank body is large, the sampling representativeness of three points of the intermediate product is not strong, the physical and chemical analysis of the semi-finished product can be detected for many times, and the production line efficiency is slowed down due to long time consumed by the physical and chemical analysis. When the raw materials are mixed and stirred, the proportion of the raw materials added at one time is too high, so that the batching efficiency is low; if a small amount of raw materials are added continuously in a proportioning manner, the overall yield is reduced, and proportioning errors are easy to occur, so that a quantitative mixing production line for powder veterinary drugs and a production method thereof are needed.

Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

The invention relates to a quantitative mixing production line of powder veterinary drugs and a production method thereof, which are connected with the background technology, for the powder which enters a tank body and is agglomerated, when the tank body is stirred, small agglomerated powder is difficult to break, so the powder veterinary drugs in the tank body are still in an uneven state after stirring, the agglomeration and the powder are filled into a packaging bag when the powder veterinary drugs are filled, when farmers actually use the veterinary drugs, the agglomeration can be completely broken, the powder of a certain component is excessive, the drug effect in the actual use process is influenced, even animal micro-poisoning can be caused, the content of each component of the drug needs to be controlled when the drug is mixed, and the problems are solved through the following structures, including a pressurizing assembly 1, an ejector assembly, a stock bin 14 and a finished product tank body 4, which are distributed according to the production flow sequence:

briefly describing the following principle: the gas in the pipeline is pressurized through the pressurizing assembly 1, so that the pressurized gas passes through the ejector pipeline 7, and the fast flow pressure in the ejector pipeline 7 is small, so that powder in each storage bin 14 is driven to enter the ejector pipeline 7, the powder is mixed in the ejector pipeline 7, and the mixed powder enters the finished product tank body 4.

The pressurizing assembly 1:

because the ejector pipeline needs to be kept in a negative pressure state, the pressure of an object is smaller when the flow speed of the object is faster according to the bernoulli principle, and therefore a component needs to be added to add pressurized air into the ejector pipeline, as shown in the attached drawing of the specification and fig. 1, the pressurized component 1 is a booster pump or a booster fan, etc., but both the booster pump and the booster fan blow air into the ejector pipeline 7, moisture in the air can affect the powder mixing effect, and particularly, the air has high humidity in continuous rainy days, which can cause powder in the ejector pipeline to agglomerate, so that the air inlet pipeline needs to be improved: as shown in the attached drawing of the specification and fig. 3, a drying assembly is arranged between the pressurizing assembly 1 and the air inlet pipeline 2, the drying assembly comprises a drying agent 5 and a humidity sensor 6, the drying agent 5 is a granular calcium chloride drying agent 5, the calcium chloride drying agent 5 has good water absorption effect and low cost, the calcium chloride drying agent 5 is arranged in a filter screen 18, the filter screen 18 is fixed on a flange of the air inlet pipeline 2, the humidity sensor 6 is arranged on the connecting pipeline 3, and a probe of the humidity sensor 6 is arranged in the connecting pipeline 3 and used for detecting the air humidity filtered by the calcium chloride drying agent 5; the humidity sensor 6 controls the actuation of the pressurizing assembly 1 and the opening and closing of a control valve 15 described below. The calcium chloride drying agent 5 is selected, which has the advantages that: the calcium chloride becomes gel after absorbing water and does not become liquid to flow out, so that the drying agent 5 is prevented from being mixed into the pipeline of the ejector after absorbing water and being combined with powder to influence the drug effect.

If only one set of drying agent 5 is provided for dry filtering of the air pumped by the pressurizing assembly 1, moist air will still enter the ejector line as soon as the selected drying agent 5 fails, so that it is desirable to improve it: as shown in FIG. 2 of the accompanying drawings, it is necessary to provide a plurality of desiccant assemblies, specifically, three groups A, B and C of desiccants 5 and humidity sensors 6 (three or three selected humidity detection probes are provided for monitoring) for drying and detecting the air entering the air intake pipe 2, the group A detection value is 10% -15% RH, the group B detection value is 6% -8% RH, and the group C detection value is 3% -5% RH. If the desiccant 5 of the group A fails, the two groups of detection numerical values of the group BC inevitably change, even if the group A is in a failure state, air can enter the ejector assembly qualified after being dried and filtered by the two groups of BC, if the desiccant 5 of the group B fails, the normal group C detection data of the group A increases suddenly, the desiccant 5 of the group B can be obtained to fail, and the desiccant 5 of the group B can also enter the ejector assembly qualified after being filtered by the group AC, the desiccant 5 of the group C fails in the same way, the detection data of the group C is the same as that of the group B, but the desiccant can also enter the ejector assembly qualified.

Generally speaking, the ABC three groups of drying agents 5 are rarely failed at the same time, the group A is replaced more frequently due to the foremost group, and the group B is replaced twice. Even if two groups of drying agents 5 fail at the same time, the normal entering into the ejector assembly can be realized, but if three groups of failures occur at the same time with a very small probability, the pressurizing assembly 1 is closed, the control valve 15 below is closed, and the whole device stops running. Set up the effect that the multiunit drier subassembly played the insurance each other to avoid directly entering into the ejector subassembly inside not having filtered air, thereby the phenomenon of caking appears when causing the powder in the ejector subassembly to mix, the following concrete structure that is the ejector subassembly:

an ejector assembly:

as shown in fig. 3 and fig. 4 of the attached drawings of the specification, the ejector assembly is connected with the air inlet pipeline 2, and comprises an ejector pipeline 7, an air inlet 8 arranged at one end of the ejector pipeline 7, a nozzle 9 arranged at the air inlet 8, and a plurality of medicament adding pipelines 10 communicated with the outer wall of the ejector pipeline 7;

an inhalation chamber 11 is arranged between the nozzle 9 and the medicament adding pipeline 10, and the inhalation chamber 11 is communicated with the medicament adding pipeline 10; because the nozzle 9 is smaller than the cross section of the air inlet pipeline 2, compared with the cross section of the air inlet pipeline 2, the cross section of the nozzle 9 is smaller, and the flow rate of the gas passing through the nozzle 9 is unchanged, the flow rate of the gas passing through the nozzle 9 is accelerated, and the bernoulli principle shows that the flow rate of the gas is fast and the pressure of the gas is small, and the pressure of the suction chamber 11 is smaller than the external atmospheric pressure, so that the medicament in the medicament adding pipeline 10 communicated with the suction chamber 11 can be absorbed into the suction chamber 11 by the ejector pipeline, and only the medicament is absorbed into the suction chamber 11 without mixing, so that a tapered section 12 is arranged between the suction chamber 11 and the connecting pipeline 3, and a diffuser section 13 is arranged in the connecting pipeline 3, and the cross section of the diffuser section 13 is larger than the tapered section 12. As shown in fig. 4 of the accompanying drawings of the specification, because the diameter of the tapered section 12 is smaller than that of the suction chamber 11, the pressurized air and various veterinary drug powders sucked in are continuously mixed in the suction chamber 11 and then enter the tapered section 12, so that the various veterinary drug powders and the pressurized air are continuously circulated in the suction chamber 11, the veterinary drug powders are uniformly mixed and then enter the diffuser section 13 from the tapered section 12, and the mixed powders are sprayed out from the diffuser section 13 and then enter the inside of the finished tank 4.

Because each composition is more accurate among the animal remedy ratio process, so need accurate control and the flow of the feed bin 14 that medicament adds pipeline 10 intercommunication, because each composition ratio is different among the pharmacy process, have major ingredient and auxiliary material etc. to constitute jointly, so need improve feed bin 14:

a stock bin 14:

as shown in fig. 3 and 4 of the attached drawings, a storage bin 14 is connected to the medicine adding pipeline 10, a medicine supplementing pipeline 17 is obliquely arranged on the storage bin 14, and the medicine is supplemented into the pipeline through the supplementing pipeline, but in order to prevent the agglomerated powder from entering the storage bin 14 when the medicine is supplemented into the storage bin 14 through the supplementing pipeline, the numerical value of the subsequent powder proportioning is affected, so that the agglomerated powder needs to be filtered out, as shown in fig. 6 of the attached drawings, a filter screen 18 is arranged at a pipe orifice of the medicine supplementing pipeline 17, the mesh number of the filter screen 18 is matched with the mesh number of the added powder, and a containing box 19 is arranged on the medicine supplementing pipeline 17. When the powder enters the storage bin 14 through self weight, the filter screen 18 filters the agglomerated powder into the containing box 19, and therefore the agglomerated powder is recovered independently.

After the powder entered into feed bin 14, a plurality of feed bins 14 were arranged in to ejector pipeline through medicament addition pipeline 10 simultaneously, mostly leaned on the dead weight of powder during row material, and the powder is relevant with the height of powder at the pressure of 14 bin discharge openings 28 of feed bin, so the powder height in every feed bin 14 need keep equal height for flow rate is the same when each feed bin 14 arranged material, but needs special attention: the amount of each component added in the preparation of a veterinary medicament is different, for example: the components of a veterinary drug comprise four components of ABCD, wherein A is 40% of the main material, B is 30% of the auxiliary material, and CD is 15% of the additive material respectively. This is improved in that the same height of the silo 14 represented by each ingredient cannot be ensured since the amounts added are different: regarding the pressure of the powder inside the silo 14, the pressure is not only related to the height of the powder, but also related to the size of the cross-sectional diameter of the tank body, as shown in the attached drawings of the specification, such as fig. 3 and fig. 5, so that the cross-sectional diameter of each silo 14 is set according to the addition ratio by changing the size of the cross-sectional diameter of each silo 14, for example, the ratio of the diameters of the four groups of silos 14 is A: b: c: d = 8.

The discharging pressure inside each silo 14 is the same, but the flow rate at the discharge port of the silo 14 plays a critical role in the accuracy of the veterinary drug ingredient proportioning, as shown in fig. 5 in the attached drawing, so that the nozzle of the drug adding pipeline 10 also needs to be improved as well: known by the flow formula, flow and pipeline sectional area are directly proportional, so improve 10 mouths of pipe to the medicament addition pipeline for the diameter that every group medicament adds the mouth of pipe is the same with medicament addition proportion, so when arranging the material, the dose that enters into ejector subassembly and inhales intracavity powder is the same with medicament addition proportion, makes the component addition of each feed bin 14 be accurate ratio. The diameter that adds pipeline 10 through changing feed bin 14 and medicament is the same with the ratio of animal remedy powder, the pipeline in the feed bin 14 has been ensured to pass through ejector subassembly suction chamber 11's negative pressure condition, the composition ratio that enters into in suction chamber 11 accords with the proportion of animal remedy production, the current medicament hybrid mode of contrast, the powder of each composition of air current mixing through suction chamber 11 mixes more evenly and is continuous mixing, mix effectually and the mixing efficiency is high, because air flow rate in the ejector subassembly is very fast, though the dose is little when mixing but the continuous effect mixing efficiency through atmospheric pressure improves greatly, be higher than current powder mixing arrangement far away.

However, when the equipment is stopped, the gravity of the powder interacts with the inner wall of the bin 14, so that the powder inside the bin 14 can form an arching and bridging phenomenon, which affects the normal falling of the powder, and thus affects the ratio of the veterinary drug powder, so as shown in the attached drawing of the specification, fig. 5, a plurality of air discs are arranged in the bin 14, the arch breaking components 16 are a plurality of air discs, the plurality of air discs are arranged on the inner wall of the bin 14, the air discs can simultaneously perform two actions of blowing and vibrating during operation, compressed air is sprayed out along the wall of the bin all around, and the edges of the air discs can generate high-frequency vibration due to the continuous change of air pressure, which effectively promote the downward flow of powder and particle materials in the bin 14, and the smooth discharging is promoted by the pneumatic principle. The excessive pressure of the powder in the bin 14 can be solved, and the acting force between powder particles is destroyed through the vibration of the air disc, so that the powder is discharged in a flowing manner when being discharged from the inside of the bin 14, and is not extruded like a fluid, and the powder in the bin 14 is prevented from blocking a discharge port 28 of the bin 14.

To timely can in time control feed bin 14 and the intercommunication that the pipeline 10 was added to the medicament, so feed bin 14 and medicament add and are equipped with control valve 15 between the pipeline 10 mouth of pipe, control is solenoid valve, electric ball valve etc. but the condition of leaking the material seepage can not appear, with the 6 signal connection of humidity transducer above, through the intercommunication that signal sensor control feed bin 14 and medicament added pipeline 10. In order to prevent the control valve 15 from closing, powder still remains on the inner wall of the medicine adding pipeline 10, so that the plurality of medicine adding pipelines 10 are obliquely arranged on the outer wall of the ejector, and the medicine is more convenient to enter the ejector assembly.

Go into connecting line 3 through pump after pressure boost subassembly 1 increases external air, through multiunit drier 5 and humidity transducer 6 in the connecting line 3, dehumidify the air of pressure boost, prevent because the too big various powder mixed effect of influence of outside air humidity leads to the powder to be dampened and is agglomerated again, can also monitor whether needing to change drier 5 simultaneously. Design feed bin 14 and medicament according to the proportion of each composition of animal remedy and add the diameter of pipeline 10 to the precision and the ratio of each powder composition addition in the control animal remedy, and can also prevent the condition that feed bin 14 blockked up at the unloading in-process, powder in every feed bin 14 enters into ejector subassembly in through mixing the back, enters into diffusion section 13 dispersion by convergent section 12 and spouts into the finished product jar body 4 in, following is the concrete structure of finished product body:

and (4) finishing the tank body:

for the finished product tank 4, the air pressurized by the pressurization assembly 1 continuously enters the finished product tank 4, so as shown in fig. 7 of the attached drawing of the specification, the finished product tank 4 needs to discharge the air, so that the finished product tank 4 is provided with an air outlet 20, the air outlet 20 is provided with a filter screen 18, the mesh number of the filter screen 18 is smaller than that of the powder with the minimum granularity in the veterinary drug formula, and in order to prevent other air in the air from entering the finished product tank 4, the air outlet 20 is connected with a check valve 21.

However, for the veterinary drug mixed in the finished tank 4, if the veterinary drug is not filled in time, the particle size segregation phenomenon between the large-particle powder and the small-particle powder may occur due to the overlarge particle size difference of each component of the powder, so that further improvement is needed: as shown in the attached figures 7 and 8 of the specification, the grain segregation preventing component comprises a material tray 22, a driving component 23, a rotating shaft connected with the driving component 23 and a shifting fork 25 connected with the rotating shaft;

the charging tray 22 is provided with a feed opening 26, and the feed opening 26 is communicated with the powder filling component and is used for filling the mixed veterinary drug; the via hole that the charging tray 22 was passed to the pivot top is fixed with the charging tray 22 cooperation, and pivot top threaded connection is equipped with awl cap 27, and awl cap 27 is used for fixed shifting fork 25. Drive assembly 23 is three phase motor and bearing room 24, and the pivot of being connected with bearing room 24 is driven through three phase motor and is rotated to drive group material fork 25 and carry out the transmission, group material fork 25 plays and lets the interior powder animal remedy that mixes of finished product jar body 4 accomplish rotate, is not to play the effect that the stirring mixes, and the animal remedy rotates the back, makes the animal remedy be in the state of motion, prevents the condition of granularity segregation after static.

Through the intercombination between pressure boost subassembly 1, ejector subassembly, feed bin 14, the finished product jar body 4, better realization when producing animal remedy powder, dampproofing, the misce bene, the proportion that the medicament added, the function of saving finished product animal remedy have formed a new line of producing, have realized better, more efficient powder animal remedy production mode.

The using method is detailed as follows:

s1, driving a pressurizing assembly 1 to generate airflow, filtering and detecting pumped gas through a plurality of groups of drying agents 5 and sensors in the pressurizing assembly 1, and after the sensors are detected to be qualified, allowing the gas to enter the ejector assembly and simultaneously opening all control valves 15 of all storage bins 14;

s2, allowing the veterinary drug powder in each stock bin 14 to enter a suction cavity of an ejector assembly for mixing, then allowing the veterinary drug powder to enter a diffusion section 13 from a reducing section 12 of a pipeline 7 of the ejector, and allowing the veterinary drug powder to enter a finished product tank 4 from the diffusion section 13; the drive assembly 23 in the finished product tank body 4 drives the rotating shaft connected with the bearing chamber 24 to rotate, so that the material shifting fork 25 is driven to transmit, and the finished veterinary drugs are discharged from the feed opening 26.

To sum up, this device forms a new powder animal remedy production line through the gaseous and efflux principle combination of ejector of pressure boost, when mixing to the powder animal remedy, can avoid the powder of each component to receive the moisture back, influences the ratio of the measurement of powder; through dehumidifying and humidity detection to the gas of pressure boost, can filter moisture in the dry air, can also detect the humidity size of the gas that enters into ejector pipeline 7 simultaneously to judge whether drier 5 became invalid. By changing the sizes of the stock bin 14 and the medicament adding pipeline 10, when veterinary medicaments with different component ratios are added into the pipeline of the ejector, the flow rate can be matched according to the medicament formula, and the medicament adding amount is accurately controlled; simultaneously can also prevent that powder animal remedy in the feed bin 14 from blockking up the pipeline and preventing the powder of each component from appearing the phenomenon of arching and bridging in feed bin 14 when flowing in to ejector pipeline, further optimization the effect of storage, ejection of compact.
