Description

Technical Field

[0001] This utility model belongs to the technical field of veterinary drug production equipment, and in particular relates to a batching device for aquatic veterinary drug production. Background Technology

[0002] Veterinary drugs are substances used to prevent, treat, and diagnose animal diseases or to purposefully regulate animal physiological functions. Their production process is largely the same as that of ordinary pharmaceuticals, and requires the mixing and formulation of various raw materials in specific proportions. Aquatic veterinary drugs, as special-purpose veterinary drugs, have even higher requirements for the precision of raw material ratios and hygiene conditions during their production.

[0003] In current pharmaceutical preparation processes, manual batching is typically used. Operators weigh raw materials according to the required proportions using electronic scales, and then a robotic arm pours the materials into a mixing tank for mixing. This traditional method has several drawbacks: firstly, manual operation is inefficient and cannot meet the needs of large-scale production; secondly, the accuracy of manual weighing is greatly affected by the operator's skill level, making it difficult to guarantee accurate proportions; and thirdly, the entire batching process is time-consuming and labor-intensive, increasing production costs. To solve these problems, engineers have developed a quantitative batching and dispensing device that uses a weighing sensor in conjunction with a weighing hopper to achieve automatic weighing and batching.

[0004] However, the aforementioned quantitative ingredient dispensing devices still have significant shortcomings in practical applications: their structural design is relatively simple, typically only capable of quantitative dispensing of a single material, and unable to simultaneously achieve precise proportioning of multiple raw materials, thus greatly limiting their functionality; furthermore, existing devices lack effective dust control measures during the dispensing process, resulting in severe dust pollution at the production site, which not only harms the health of operators but also increases the workload of cleaning and maintenance, especially in the production of aquatic veterinary drugs where raw materials are mostly in powder or granular form, making the dust problem even more prominent. Therefore, there is an urgent need to design a dispensing device for aquatic veterinary drug production to solve the above problems. Summary of the Invention

[0016] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail: Please see Figure 1 The feed preparation device for aquatic veterinary drug production of this utility model includes a mounting bracket 19, on which a sealed protective box 4 is mounted. A horizontally arranged mounting partition 12 is fixedly connected inside the sealed protective box 4, dividing its interior into an upper feeding chamber 10 and a lower feeding chamber 13 distributed vertically. At least two sets of discharging components 8 are fixedly connected inside the upper feeding chamber 10. Multiple slots corresponding to the discharge ports of the multiple discharging components 8 are opened on the mounting partition 12. Multiple feeding hoppers 9 are provided on the top of the sealed protective box 4, each connecting to the inlet of the multiple discharging components 8. To prevent dust from flying, a cover plate is installed at the top opening of the feeding hoppers 9, and a feeding port is provided on the cover plate.

[0017] In addition, a feed cover 6 is provided in the lower feeding chamber 13, which is fixed to the mounting partition 12 and respectively connected to the discharge ports of multiple feeding components 8. A weighing hopper assembly 5 is provided in the lower feeding chamber 13, which is respectively connected to multiple corresponding and gap-fitted weighing hopper assemblies 5. Several weighing sensors 7 are provided between each weighing hopper assembly 5 and the mounting partition 12 to connect the two. It also includes a mixing hopper 3 installed on the mounting bracket 19 and connected to the lower port of the lower feeding chamber 13, which is used to receive the material falling from each weighing hopper assembly 5. A vibration motor 22 is installed on the outer wall of the mixing hopper 3. An auger feeding assembly is installed at the discharge port of the mixing hopper 3. It also includes a pipeline structure that is connected to the upper feeding chamber 10 and the lower feeding chamber 13 respectively. A dust removal assembly is installed at the air outlet of the pipeline structure. It also includes a dust collection box 20 installed at the discharge port of the dust removal assembly.

[0018] The mounting bracket 19 refers to the rigid frame structure that supports the entire device. It can be constructed using steel welding or bolt assembly, providing stable support for the sealed protective box 4. The sealed protective box 4 is a closed box structure, which can be formed by splicing metal sheets, creating a sealed working space to prevent dust from escaping. The mounting partition 12 is a horizontally installed isolation plate, which can be cut from steel plates to separate upper and lower independent working areas, avoiding cross-contamination.

[0019] The material discharge assembly 8 refers to the material temporary storage and release mechanism, which can specifically adopt a funnel structure with a valve to achieve independent storage and quantitative release of multiple raw materials. The weighing hopper assembly 5 refers to the material weighing container, which can specifically be made of stainless steel, and the weight of the material is monitored in real time by the weighing sensor 7. The mixing hopper 3 refers to the material mixing container, which can specifically adopt a conical structure, and the material flow and mixing are promoted by the vibrating motor 22. The auger feeding assembly refers to the screw conveyor mechanism, which can specifically adopt a motor to drive the screw blades to rotate, so as to achieve continuous discharge. By setting the aforementioned vibrating motor 22, the phenomenon of material forming a dome shape at the discharge port of the mixing hopper 3 and obstructing the discharge can also be avoided. In order to improve the mixing effect of the material in the mixing hopper 3, a stirring structure can be set in the mixing hopper 3, and a motor for driving the rotation of the stirring structure can be set on the mounting bracket 19. The stirring structure adopts a commercially available structure.

[0020] The aforementioned piping structure refers to the gas flow channel, which can be specifically constructed using metal pipes to connect each chamber to the dust collection equipment, creating a negative pressure airflow. The dust collection component refers to the dust filtration device, which can specifically employ a combination of cyclone separator and bag filter to separate and collect suspended particles.

[0021] like Figure 1As shown, the above-mentioned pipeline structure includes an air outlet pipeline 11 that is connected to the upper feeding chamber 10 and the lower feeding chamber 13 respectively. The two air outlet pipelines 11 are connected by a T-joint. It also includes an air supply pipeline 15 connected to the T-joint. A control valve is installed on the air supply pipeline 15. The air outlet of the air supply pipeline 15 is connected to the air inlet provided on the outer wall of the cyclone dust collector 16. The above-mentioned dust removal assembly includes a cyclone dust collector 16 and a filter cartridge structure 18 installed on the mounting bracket 19. The air inlet on the outer wall of the cyclone dust collector 16 is connected to the air outlet of the pipeline structure. It also includes a fan 14 installed at the top air outlet of the cyclone dust collector 16. The air outlet of the fan 14 is connected to the air inlet provided on the outer wall of the filter cartridge structure 18 through a pipeline. It also includes a filter bag mechanism 17 installed inside the filter cartridge structure 18.

[0022] Among them, the cyclone dust collector 16 refers to a device that uses centrifugal force to achieve gas-solid separation. Specifically, it can be implemented using a metal shell structure with a tangential air inlet and a conical bottom, which causes large dust particles to settle through high-speed rotating airflow. The filter cartridge structure 18 refers to a closed filter container composed of a cylinder and a cover. Specifically, it can be implemented using a combination structure of a cylindrical metal cylinder with flange connection and a detachable cover plate, which facilitates the installation and replacement of filter bags. The filter bag mechanism 17 refers to a filter unit composed of a supporting frame and fiber filter cloth. Specifically, it can be implemented using a structure of a metal mesh frame covered with a polyester fiber cloth bag, used to capture fine dust.

[0023] The filter cartridge structure 18 includes a filter cartridge body and a cover that are locked together. A mounting plate for installing a filter bag mechanism 17 is installed on the mating surface of the filter cartridge body and the cover. The filter bag mechanism 17 includes a bag support inserted into the mounting plate, and a filter bag is fitted over the bag support. This split-type, docking design of the filter cartridge body and cover allows for quick disassembly and locking, facilitating the maintenance and replacement of the filter components.

[0024] Specifically, the dust-laden airflow enters the tangential inlet of the cyclone dust collector 16 through a pipeline. Under centrifugal force, large dust particles are thrown against the cylinder wall and fall into the bottom collection area. The purified airflow is drawn to the filter cartridge structure 18 by the fan 14 through the top outlet. After entering the cylinder from the outer wall inlet, the airflow diffuses evenly. When passing through the filter bag mechanism 17, the remaining fine dust is intercepted by the filter cloth. The filtered clean air is discharged from the system, completing the dust collection. The cyclone dust collector 16 and the filter cartridge structure 18 form a two-stage dust removal system, which classifies and treats dust particles of different sizes.

[0025] Compared with existing technologies, traditional dust removal devices mostly use a single filtration method, such as bag filtration or cyclone separation, which has problems such as low processing efficiency and easy clogging of filter bags. This solution uses a series design of cyclone dust collector 16 and filter cartridge structure 18 to first remove large dust particles through centrifugal separation, reducing the load on subsequent filter bags. At the same time, the negative pressure generated by fan 14 enhances airflow conveying efficiency, forming a synergistic effect.

[0026] Through the above technical solution, this application achieves efficient collection of dust generated during the batching process, effectively preventing powder leakage into the external environment, reducing the risk of operators inhaling dust, and reducing the cleaning frequency caused by dust accumulation inside the equipment, thereby improving the continuity and stability of system operation.

[0027] like Figure 2 As shown, the above-mentioned feeding assembly 8 includes a feeding box structure 8-3, a feeding hopper mechanism 8-1 is provided in the feeding box structure 8-3, the feeding port of the feeding hopper mechanism 8-1 is connected to the feeding hopper 9, and also includes a feeding valve mechanism 8-2 for controlling the opening and closing of the discharging port of the feeding hopper mechanism 8-1.

[0028] The modular feeding assembly 8, constructed using the above configuration, enables independent control of multiple raw materials. The feeding box structure 8-3 serves as the basic support frame, providing installation space for the feeding hopper mechanism 8-1 and the feeding valve mechanism 8-2. The feeding hopper mechanism 8-1 directly connects with the feeding hopper 9 to form a sealed channel, ensuring directional conveying of raw materials. The feeding valve mechanism 8-2, through mechanical linkage, precisely controls the opening and closing of the discharge port, achieving both precise control of quantitative feeding and forming a physical barrier to prevent dust diffusion. These three components work together to form a closed feeding unit, satisfying the independent proportioning requirements of various raw materials while suppressing dust overflow at the source through structural sealing.

[0029] See further Figure 4The aforementioned discharge valve mechanism 8-2 includes a valve plate shaft 8-2-7 that transversely penetrates and rotatably connects to the discharge box structure 8-3. Valve plate connecting plates 8-2-8, respectively located on both sides of the discharge hopper mechanism 8-1, are mounted on the valve plate shaft 8-2-7. A discharge valve plate 8-2-1, which matches the discharge port of the discharge hopper mechanism 8-1 and has an arc-shaped structure, is fixed between the two valve plate connecting plates 8-2-8. A shaft swing arm 8-2-2 is fixedly connected to one end of the valve plate shaft 8-2-7. The mechanism also includes a valve plate shaft 8-2-7 that transversely penetrates and rotatably connects to the discharge box structure 8-3. The structure 8-3 includes a drive connecting plate 8-2-5 pivotally connected to the outer wall of the structure, and a feeding linear drive 8-2-4 pivotally connected between the middle of the drive connecting plate 8-2-5 and the outer end of the shaft swing arm 8-2-2; it also includes a flange shaft 8-2-3 mounted on the outer wall of the feeding box structure 8-3, and a feeding linear drive 8-2-6 pivotally connected between the flange shaft 8-2-3 and the outer end of the drive connecting plate 8-2-5, with the feeding linear drive 8-2-6 located above the feeding linear drive 8-2-4.

[0030] A dual-pivot rotation structure is constructed through the transversely arranged valve plate pivot 8-2-7, which, together with the rigid connecting frame formed by the valve plate connecting plates 8-2-8 on both sides, enables the arc-shaped discharge valve plate 8-2-1 to achieve precise alignment and sealing with the discharge port. A specially designed dual linear drive mechanism forms a composite drive system: the first discharge linear drive 8-2-4 achieves the main motion control of the valve plate pivot 8-2-7 through the linkage of the drive connecting plate 8-2-5 and the shaft swing arm 8-2-2, while the second discharge linear drive 8-2-6, located above, forms an auxiliary power source through the connection of the flange shaft 8-2-3 and the drive connecting plate 8-2-5. This dual-drive arrangement ensures the stability of the valve opening and closing action and reduces the load on a single actuator through mechanical distribution. The dual linear drive mechanism refers to a drive system composed of two independent hydraulic cylinders or electric actuators, specifically adjustable-stroke servo electric cylinders, arranged in a staggered manner to form a torque-complementary drive mode.

[0031] like Figure 4 As shown, the above-mentioned hopper mechanism 8-1 includes a hopper body 8-1-1 connected to the hopper box structure 8-3. A window is provided on the back plate of the hopper body 8-1-1, and a maintenance back plate 8-1-2 that is detachably connected to the hopper body 8-1-1 is provided at the window. A slot is provided on the upper part of the side wall of the hopper body 8-1-1, and an exhaust box 8-1-3 that is clearance-fitted with the inner wall of the hopper box structure 8-3 is provided at the slot.

[0032] A stable material channel is formed by connecting the hopper body 8-1-1 and the discharge box structure 8-3. The maintenance back plate 8-1-2 adopts a detachable connection method to achieve quick disassembly and maintenance, solving the problem of difficult maintenance of traditional enclosed hoppers. An exhaust box 8-1-3 with a clearance fit is set on the side wall of the hopper body 8-1-1. It can achieve air pressure balance inside the discharge box through the slot structure, and the clearance fit can form an airflow buffer area, effectively preventing dust from directly overflowing with the airflow. The coordinated design of the maintenance back plate 8-1-2 and the exhaust box 8-1-3 ensures the airtightness of the equipment while taking into account the convenience of maintenance and dust control requirements.

[0033] like Figure 5 As shown, the weighing hopper assembly 5 includes a reinforced mounting frame 5-1 connected to the weighing sensor 7, a weighing hopper body 5-2 mounted on the reinforced mounting frame 5-1, a window on the side wall of the weighing hopper body 5-2 and a weighing inspection door 5-4 pivotally connected to the window, and a locking fastener 5-3 for locking the weighing inspection door 5-4 and the weighing hopper body 5-2 together; a weighing valve plate 5-5 with an arc-shaped structure is rotatably connected to the outlet of the weighing hopper body 5-2, and a feeding linear drive 5-6 pivotally mounted on the weighing hopper body 5-2, with the extended end of the feeding linear drive 5-6 pivotally connected to the upper end of the weighing valve plate 5-5.

[0034] By strengthening the connection structure between the mounting frame 5-1 and the weighing sensor 7, the overall rigidity of the weighing hopper assembly 5 is enhanced, ensuring uniform and stable force distribution during the weighing process. The reinforced mounting frame 5-1 refers to the frame structure that is fixedly connected to the weighing sensor 7. This can be achieved by welding or bolting, and is used to improve the structural rigidity of the weighing hopper body 5-2 and distribute the load.

[0035] The rotating fit structure between the arc-shaped weighing valve plate 5-5 and the outlet of the weighing hopper body 5-2, combined with the precise control of the valve plate opening and closing angle by the linear drive device, realizes the gradual opening and closing operation of quantitative feeding, avoiding weighing errors caused by instantaneous material pouring; the linear drive device and the valve plate adopt a pivot connection, which not only ensures the effective transmission of driving force, but also allows the valve plate to adaptively adjust the angle during the movement, ensuring a tight seal between the sealing surfaces.

[0036] like Figure 4 As shown, the cylinder of the above-mentioned feeding linear drive 8-2-6 is pivotally connected to the flange shaft 8-2-3, and its extended end is pivotally connected to the outer end of the drive connecting plate 8-2-5 through a Y-type joint; the cylinder of the feeding linear drive 8-2-4 is pivotally connected to the middle of the drive connecting plate 8-2-5, and its extended end is pivotally connected to the outer end of the shaft swing arm 8-2-2 through a Y-type joint.

[0037] The linear drive for material discharge 8-2-4 adopts a central pivot drive plate 8-2-5 design, combined with the linkage between the Y-type joint and the shaft swing arm 8-2-2, forming a dual-drive synergy. This allows the arc-shaped sealing surface of the discharge valve plate 8-2-1 to precisely fit the discharge port of the hopper mechanism 8-1. The two sets of linear drives form a compound lever effect through spatial staggered layout, ensuring the synchronicity of the valve plate opening and closing actions while avoiding sealing failure caused by single-point force.

[0038] See further Figure 3 The aforementioned material discharge box structure 8-3 includes a material discharge box body 8-3-1 whose top is connected to the top of the sealed protective box 4 and whose bottom is connected to the mounting partition 12. An inspection window 8-3-2 is provided on the side wall of the material discharge box body 8-3-1, which is opposite to the inspection back plate 8-1-2 and has a cover fastened to it. An extension side plate 8-3-3 for installing the material discharge valve mechanism 8-2 is installed on the side wall of the material discharge box body 8-3-1.

[0039] The double connection structure between the discharge box body 8-3-1 and the top of the sealed protective box 4 and the mounting partition 12 forms a closed box space, effectively blocking the diffusion path of dust generated during the discharge process. The design of the inspection window 8-3-2 and the snap-on cover provides a convenient maintenance channel while ensuring the airtightness of the box, allowing for maintenance of the internal discharge hopper mechanism 8-1 without disassembling the entire structure. This structural design improves the sealing performance of the equipment while realizing the modular layout of key components and rapid maintenance functions.

[0040] like Figure 1 As shown, the aforementioned auger feeding assembly includes a transversely arranged transmission cylinder 2, the inlet of the transmission cylinder 2 being connected to the outlet of the mixing hopper 3, and the outlet of the transmission cylinder 2 being connected to the inlet of the mixing equipment; a transmission auger 1 is rotatably connected to the transmission cylinder 2, and an auger motor 21 for driving the transmission auger 1 to rotate is also included.

[0041] The transversely positioned conveyor cylinder 2 directly connects to the discharge port of the mixing hopper 3, forming a closed material conveying channel. This prevents the mixed powder from being exposed to the external environment during transfer, thus suppressing dust diffusion. As the conveyor auger 1 rotates inside the cylinder, its spiral blades continuously push the material from the inlet to the outlet, solving the problems of material accumulation or blockage that easily occur with traditional gravity feeding and ensuring the stability of the conveying process. The driving action of the auger motor 21 allows the conveyor auger 1 to adjust its speed according to actual needs, thereby controlling the material conveying volume and meeting the refined requirements of conveying efficiency for different mixing processes. The docking design between the conveyor cylinder 2 and the inlet of the mixing equipment further realizes fully enclosed operation, reducing manual intervention and lowering the risk of secondary pollution.

[0042] Working principle: Specifically, materials are temporarily stored in corresponding discharge components 8 through multiple feed hoppers 9. When batching is required, the discharge component 8 opens according to a set program, and the material falls into the lower feeding chamber 13 through the slot of the mounting baffle 12. The feed hood 6 guides the material into the corresponding weighing hopper component 5, and the weighing sensor 7 monitors the material weight in real time until it reaches the preset value. The weighed material is released from the bottom of the weighing hopper component 5 into the mixing hopper 3, and the vibration motor 22 promotes uniform mixing of the material. The mixed material is then conveyed to the next process by the auger feeding component. Dust-laden gas generated during the operation is introduced into the dust removal component through the pipeline structure. Large dust particles fall into the dust collection box 20 through cyclone separation, while fine particles are discharged after being filtered by a filter bag.

[0043] Compared to existing technologies, traditional devices only have a single weighing unit, requiring the sequential weighing of multiple raw materials, resulting in low operational efficiency. This solution achieves simultaneous weighing and proportioning of multiple raw materials by using multiple sets of discharging components 8 and weighing hopper components 5 working in parallel. Existing equipment uses an open structure, allowing dust to easily spread into the external environment. This solution, through a sealed protective box 4 and a compartmentalized design, confines dust within a closed space, and, in conjunction with a dust removal system, effectively collects suspended particles, reducing environmental pollution. Traditional manual operation requires repeated opening and closing of valves; this solution, through the linkage of weighing sensors 7 and automatic valves, achieves precise quantitative control.
