Description
Technical Field
The invention relates to the field of veterinary medicine production, in particular to a quantitative mixing production device for powder veterinary medicines.
Background
For veterinary drug production, most of western veterinary drugs or traditional Chinese veterinary drugs are sold in the form of powder, but in the powder veterinary drug production process, various materials are required to be mixed and proportioned in a tank body, the various materials are added in the tank body by the existing production line, and then the materials are uniformly mixed and proportioned by continuous stirring, and the medicines are filled after uniform mixing.
However, the method has great disadvantages, whether the mixing proportion of various raw materials in the tank body is completely and uniformly mixed, and whether the content of each component after mixing meets the standard is unknown; in addition, once the raw materials added into the tank body are wetted and agglomerated, the content of each component proportion can be directly influenced, and meanwhile, the uniformity of the material proportion can be influenced; when raw materials are added into the tank body, once the raw materials are arched, bridged and the like in the tank body, the discharge flow is uneven, and the situation of less materials or no discharge occurs, so that the accuracy of the proportion of the final components of the veterinary drug powder in the production process is affected; and when mixing and stirring the raw materials, the humidity content in the tank body cannot be known, if the humidity of the raw materials is too high, caking still occurs in the stirring process, and the flowability of the materials and the quality of the finished products can be influenced during final filling.
For the powder stirring process, the optimal time point of uniform mixing is not well and accurately grasped, continuous stirring is required in the tank body according to the standard mixing time, the middle detection is required to be carried out on the upper, middle and lower three points in the tank body for the determination of the standard time, and whether the mixing is continued or not is determined, and the like until all the three points reach the qualified standard range. And the standard time in each powder stirring process is 25-40 minutes, the mixing and stirring time is long, if the volume of the mixing tank body is large, the sampling representativeness of three points of intermediate products is not strong, and the multi-time detection of semi-finished products for physicochemical analysis can occur, so that the efficiency of the production line is reduced due to long time consumption of the physicochemical analysis. When the raw materials are mixed and stirred, the proportion of the raw materials added at one time is overlarge, so that the batching efficiency is low; if a small amount of raw materials are continuously added in proportion, the overall yield is reduced and the proportion error is easy to occur, so that a quantitative mixing production device for powder veterinary medicines is needed.

Detailed Description
The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. Further, it will be understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the application, and equivalents thereof fall within the scope of the application as defined by the claims.
The invention relates to a quantitative mixing production device for powder veterinary drugs, which is characterized in that as described in the background art, when powder which enters a tank body and is agglomerated is stirred in the tank body, small agglomerated powder is difficult to break, so that the powder veterinary drugs in the tank body are still in an uneven state after being stirred, the agglomeration and the powder are filled into a packaging bag together when the powder veterinary drugs are filled, and when a farmer actually uses the veterinary drugs, the agglomeration is found to be crushed and used completely, so that the excessive powder of a certain component can influence the drug effect in the actual use process, even animal micro-poisoning can be caused, and the content of each component of the drug must be controlled when the drug is mixed.
As shown in fig. 1 and 3 of the drawings, the problems described above, including the ejector assembly, the silo 10 and the finished tank 2, are solved by the following structures, and special attention is required before the detailed description of each structure: the ejector assembly is based on the jet principle of the ejector, and pressurized gas must be pumped into the ejector pipeline on the premise of realizing the ejector principle, so the ejector assembly and the ejector assembly should be connected through a pipeline booster pump 23 or a booster fan and other booster assemblies. However, the booster pump 23 and the booster fan are both air blowing to the inside of the ejector pipeline 3, and moisture in the air can affect the powder mixing effect, especially, the air humidity is high in overcast and rainy continuous weather, so that the powder in the ejector pipeline is agglomerated, and the pumped air needs to be dried through the calcium chloride drying agent 27. Because the desiccant 27 will fail after a period of use, the humidity of the pumped air needs to be monitored, if the humidity detection value does not reach the standard, the air cannot be pumped into the ejector pipeline like the air, because the flow rate of the pressurized air is fast, even if the sensor detects that the humidity does not reach the standard, the operation is stopped in time, but because the ejector sucks the powder in the chamber 7 to cause the influence, the desiccant 27 and the humidity sensor 24 need to be arranged in multiple groups, and the influence caused by the failure of only one group of desiccant 27 is avoided. The following is a specific structure of the jet assembly:
jet assembly:
as shown in fig. 3 and 4 of the drawings, the ejector assembly is connected with the air inlet pipeline 28, and comprises an ejector pipeline 3, an air inlet 4 arranged at one end of the ejector pipeline 3, a nozzle 5 arranged at the air inlet 4, and a plurality of medicament adding pipelines 6 communicated with the outer wall of the ejector pipeline 3;
An inhalation chamber 7 is arranged between the nozzle 5 and the medicament adding pipeline 6, and the inhalation chamber 7 is communicated with the medicament adding pipeline 6; since the nozzle 5 is smaller than the inlet pipe 28 compared with the inlet pipe 28, the flow rate of the gas is not changed because the section of the nozzle 5 is smaller, so the gas flow rate passing through the nozzle 5 is faster, the gas flow rate is fast, the pressure is small, the pressure of the suction chamber 7 is smaller than the external atmospheric pressure, so the medicine in the medicine adding pipe 6 communicated with the suction chamber 7 is absorbed into the suction chamber 7 by the ejector pipe, only the medicine is sucked into the suction chamber 7 and is not mixed, a taper section 8 is arranged between the suction chamber 7 and the connecting pipe 1, a diffusion section 9 is arranged in the connecting pipe 1, and the section of the diffusion section 9 is larger than the taper section 8. As shown in figure 4 of the accompanying drawings, because the diameter of the tapered section 8 is smaller than that of the suction chamber 7, pressurized air and various sucked veterinary drugs are continuously mixed in the suction chamber 7 and then enter the tapered section 8, so that various veterinary drugs and the pressurized air are continuously circulated in the suction chamber 7, the veterinary drugs enter the diffusion section 9 from the tapered section 8 after being uniformly mixed, and the mixed powder enters the finished product tank 2 after being sprayed out from the diffusion section 9.
Because each ingredient is more accurate in the veterinary drug proportioning process, the flow of the bin 10 communicated with the drug adding pipeline 6 needs to be accurately controlled, and because each ingredient is different in proportion in the pharmaceutical process and is composed of main materials, auxiliary materials and the like, the bin 10 needs to be improved:
Stock bin 10:
As shown in fig. 3 and 4 of the accompanying drawings, the medicine adding pipeline 6 is connected with a storage bin 10, a medicine supplementing pipeline 13 is obliquely arranged on the storage bin 10, and medicine is supplemented into the pipeline through the supplementing pipeline, but in order to prevent the numerical value of the ratio of the subsequent powder from being influenced by the agglomerated powder when the medicine is supplemented into the storage bin 10 through the supplementing pipeline, the agglomerated powder needs to be filtered out, as shown in fig. 6 of the accompanying drawings, a filter screen 14 is arranged at the mouth of the medicine supplementing pipeline 13, the mesh number of the filter screen 14 is matched with the mesh number of the added powder, and the medicine supplementing pipeline 13 is provided with a containing box 15. So that the powder enters the bin 10 by its own weight, the filter screen 14 filters the agglomerated powder into the holding box 15, thereby recovering the agglomerated powder alone.
After the powder enters the bin 10, the plurality of bins 10 are simultaneously discharged into the ejector pipeline through the medicament adding pipeline 6, and the gravity of the powder is mostly used for discharging, the pressure of the powder at the discharge opening 25 of the bin 10 is related to the height of the powder, so the height of the powder in each bin 10 needs to be kept at the same height, the flow rate is the same when each bin 10 is discharged, and special attention is paid to the fact that: the amount of each component added in the preparation of veterinary drug is different, for example: the veterinary medicine comprises four components of ABCD, wherein A is 40% of main material, B is 30% of auxiliary material, C, D is 15% of additive. Since the addition amounts of the respective components are different, it is impossible to ensure the same height of the bin 10 represented by the respective components, and thus improvement is made: as for the pressure of the powder in the bin 10, the pressure is not only related to the height of the powder, but also related to the cross-sectional diameter of the tank body, as shown in fig. 3 and 5 of the specification, the cross-sectional diameter of each bin 10 is set according to the adding proportion by changing the cross-sectional diameter of each bin 10, for example, the proportion of the diameters of the four groups of bins 10 is a: b: c: d=8:6:3:3 so that the volume of each set of bins 10 is the same as the addition ratio of the medicament, so that at the time of discharging, even though the addition amount of each bin 10 is different, the consumption amount of the powder in each bin 10 is the same as the volume ratio of the bin 10, so that the change in height for the bin 10 is the same, so that the pressure of the powder in each bin 10 is approximately the same.
The above-mentioned only realizes that the discharge pressure inside each bin 10 is the same, but for the flow of the discharge hole of the bin 10, the accuracy of the veterinary medicine component proportion plays a key role, as shown in fig. 5 of the specification and the attached drawings, so that the same needs to be improved on the mouth of the medicine adding pipeline 6: the flow formula shows that the flow is in direct proportion to the sectional area of the pipeline, so that the pipe orifice of the medicament adding pipeline 6 is improved, the diameter of each group of medicament adding pipe orifices is the same as the medicament adding proportion, and the dosage of powder entering the suction cavity of the ejector assembly is the same as the medicament adding proportion during discharging, so that the component addition of each bin 10 is in accurate proportion. The diameter through changing feed bin 10 and medicament add pipeline 6 is the same with the ratio of animal remedy powder, the pipeline in the feed bin 10 has been guaranteed through the negative pressure condition of ejector subassembly suction chamber 7, the proportion of the ingredient that enters into in suction chamber 7 accords with the proportion of animal remedy production, compare current medicament mixing mode, the powder mix of each composition of air current through suction chamber 7 is more even and continuous mixing, it is effectual and mixing efficiency is high to mix, because the air velocity in the ejector subassembly is very fast, so though the dose is little but the continuous effect mixing efficiency through atmospheric pressure improves greatly when mixing, far above current powder mixing arrangement.
However, when the equipment is stopped, the gravity of the powder and the inner wall of the bin 10 interact, so that the powder in the bin 10 can form a phenomenon of arch bridging to influence the normal falling of the powder and further influence the proportion of veterinary medicine powder, so that as shown in the figure 5 of the specification, an arch breaking assembly 12 is arranged in the bin 10, the arch breaking assembly 12 is a plurality of air discs, the plurality of air discs are arranged on the inner wall of the bin 10, the air discs can simultaneously generate two actions of blowing and vibrating when working, compressed air is sprayed to the periphery along the wall of the bin, and the edges of the air discs can generate high-frequency vibration due to the continuous change of air pressure, so that the powder and the granular materials in the bin 10 are effectively promoted to flow downwards, and smooth discharging is promoted through a pneumatic principle. The pressure of the inside powder of feed bin 10 is too big can also be solved, through the vibration of gas dish, the effort between the destruction powder granule for the powder is the discharge that flows when discharging from the inside of feed bin 10, and not is the fluid and extrudes, thereby the powder avoids blockking up feed bin 10 bin outlet 25 in the feed bin 10.
To the intercommunication that in time can in time control feed bin 10 and medicament add pipeline 6, so be equipped with control valve 11 between feed bin 10 and the mouth of pipe of medicament add pipeline 6, control is solenoid valve, electric ball valve etc. but the condition that leaks material oozes can not appear, with above humidity transducer 24 signal connection, through signal transducer control feed bin 10 and medicament add pipeline 6's intercommunication. In order to prevent the control valve 11 from closing, powder still remains on the inner wall of the medicament adding pipeline 6, so that the medicament adding pipelines 6 are obliquely arranged on the outer wall of the ejector, and the medicament entering the ejector assembly is more convenient.
The air outside is pumped into the connecting pipeline 1 after being increased through the pressurizing assembly, the pressurized air is dehumidified through the multiple groups of drying agents 27 and the humidity sensor 24 in the connecting pipeline 1, various powder mixing effects are prevented from being influenced due to overlarge outside air humidity, the powder is prevented from being damped again and agglomerated, and meanwhile whether the drying agents 27 need to be replaced or not can be monitored. The diameters of the bin 10 and the medicament adding pipeline 6 are designed according to the proportion of each component of the veterinary medicament, so that the accuracy and the proportion of the adding amount of each powder component in the veterinary medicament are controlled, the bin 10 can be prevented from being blocked in the blanking process, powder in each bin 10 enters into a jet assembly to be mixed, and then enters into a diffusion section 9 by a tapering section 8 to be dispersed and sprayed into a finished product tank body 2, and the following is a specific structure of the finished product pipe body:
