Description

Technical Field

[0001] This utility model relates to the field of veterinary drug filling equipment technology, specifically to an easy-to-clean veterinary drug liquid preparation filling equipment. Background Technology

[0002] The filling and production of liquid veterinary drug formulations is a core step in veterinary drug manufacturing. Veterinary drug ingredients often contain high-viscosity active substances, corrosive solvents, and easily crystallizing components.

[0003] Current filling equipment generally has a structure similar to that described in patent application number "CN202020842752.3", including a base, a horizontally arranged conveyor belt on the base, a storage box fixedly connected to the base at a position above the middle of the conveyor belt, an opening at the top of the storage box with a cross-section equal to the internal cross-section of the storage box, a feeding port at the top of the side wall of the storage box, and a discharge port at the bottom of the storage box. A discharge pipe is slidably connected to the discharge port, the top of the discharge pipe is closed, the discharge pipe is vertically arranged, and can slide in the vertical direction. A filling head is fixedly connected to the bottom of the discharge pipe. A filling hole is opened at the top of the side wall of the discharge pipe, and an extrusion plate with a cross-section equal to the internal cross-section of the storage box is fixedly connected to the top of the discharge pipe. The extrusion plate is slidably connected in the storage box and can slide in the vertical direction. A sliding component for controlling the sliding of the extrusion plate is provided on the storage box.

[0004] In existing veterinary drug liquid preparation filling processes, drug residue easily remains inside the filling head. This residue, once dried, can clog the filling head, leading to inaccurate filling volumes or even complete filling failure. Furthermore, the long-term accumulation of this residue not only breeds bacteria, affecting the quality of subsequent veterinary drug products, but also reacts chemically with newly filled drug solutions, altering their composition and properties, thus reducing the efficacy of the veterinary drug. Current methods often involve periodically disassembling and manually cleaning the filling head. Each cleaning is time-consuming and labor-intensive, reducing equipment utilization. Frequent replacement and disassembly of the filling head increases production costs, disrupts normal equipment operation, and reduces overall production efficiency.

[0005] Therefore, this utility model proposes an easy-to-clean veterinary drug liquid preparation filling equipment to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide an easy-to-clean veterinary drug liquid preparation filling equipment to solve the problem of time-consuming and labor-intensive cleaning of the filling head in the existing technology, which leads to a decrease in equipment utilization.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A veterinary drug liquid preparation filling device that is easy to clean includes a filling mechanism. The filling mechanism includes a body, filling heads, and a piston pump. The piston pump is connected to the upper end of the body. A mounting plate is longitudinally slidably connected to the body. Multiple filling heads are evenly connected to the mounting plate. A first drive cylinder connects the body and the mounting plate. Each filling head is connected to the outlet pipe of the piston pump via an infusion pipe. A cleaning pipe is connected to the inlet pipe of the piston pump via a three-way valve. The cleaning pipe communicates with a cleaning agent storage tank. The storage tank is connected to the upper end of the machine body; the lower end of the filling head is provided with a cleaning tank, which is slidably connected to a sleeve rod via a collar, the sleeve rod is fixedly connected to the machine body, the collar is connected to the piston rod of the second drive cylinder, and the second drive cylinder is fixedly connected to the machine body; multiple multi-angle nozzles are evenly connected inside the cleaning tank, and each multi-angle nozzle is connected to the cleaning agent storage tank via a connecting pipe; a drain pipe is connected to the bottom of the cleaning tank; a conveying mechanism is provided at the lower end of the cleaning tank, and the conveying mechanism corresponds to the filling head.

[0009] By adopting the above technical solution, the piston pump and its connecting pipes can be cleaned, effectively dissolving and flushing away residual medicine, preventing the filling head from clogging after the medicine dries, thoroughly cleaning the residual medicine inside the filling head, preventing bacteria growth from the residual medicine, saving a lot of manpower and time costs, and improving the utilization rate of the equipment.

[0010] Furthermore, the cleaning agent storage tank is equipped with a stirring paddle and a heating coil.

[0012] Furthermore, the piston pump's outlet pipe is also connected to a flow regulating valve and a pressure regulating valve.

[0013] By adopting the above technical solution, the flow rate and pressure of the liquid can be precisely adjusted according to different filling requirements, thereby controlling the flow rate and pressure of the cleaning solution and improving the cleaning effect.

[0014] Furthermore, a drying device is connected to the side wall of the machine body, and the drying device corresponds to the filling head.

[0015] By adopting the above technical solution, the filling head can be dried in time after cleaning to prevent residual moisture from breeding bacteria and further ensure product quality.

[0016] Furthermore, container positioning frames are symmetrically provided on both sides of the conveying mechanism, and the container positioning frames are connected to the conveying mechanism through height adjustment screws.

[0017] By adopting the above technical solution, the container positioning frame can position the container during the conveying process, ensuring that the container is accurately positioned during filling and avoiding filling errors caused by container shaking; at the same time, the height adjustment screw can be adjusted according to the height of different containers, adapting to the filling of various container sizes and improving the versatility of the equipment.

[0019] By adopting the above technical solution, waste liquid can be centrally treated, facilitating its complete discharge.

[0020] Furthermore, the side wall of the storage tank is provided with a liquid level observation window.

[0021] By adopting the above technical solution, during the cleaning process, the staff can observe the liquid level of the waste liquid in the tank through the liquid level observation window on the side wall of the storage tank. When a certain liquid level is reached, the drain port at the bottom of the storage tank is opened to discharge the waste liquid.

[0022] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention features multiple multi-angle nozzles evenly distributed within the cleaning tank, which spray cleaning agent onto the filling head from different directions. Simultaneously, the cleaning agent enters the inlet pipe of the piston pump through a three-way valve, cleaning the piston pump and its connecting pipes. This effectively dissolves and flushes away residual medication, preventing the filling head from clogging after the medication dries. It thoroughly cleans away any residual medication inside the filling head, preventing bacterial growth from the residual medication, saving significant manpower and time costs, and improving equipment utilization.

Next, the drying device 29 on the side wall of the machine body 1 is activated to dry the filling head 2, removing residual moisture and preventing bacterial growth, ensuring the cleanliness and hygiene of the filling head 2, and preparing it for the next filling operation. Then, the drain valve 18 at the bottom of the cleaning agent storage tank 13 is opened to drain the remaining cleaning agent from the tank.
