Description

Technical Field

[0001] This utility model belongs to the field of veterinary instruments, specifically relating to a continuous immersion inoculation device for fish vaccines based on an Archimedes screw, which is particularly suitable for automated continuous immunization in large-scale fish populations. Background Technology

[0002] Traditional fish vaccination relies on manual operation, resulting in low vaccination efficiency, low vaccine utilization, stress damage to fish, and difficulty in dissolved oxygen control. While automated injection equipment exists, it is unsuitable for small-sized fry. Immersion inoculation devices, on the other hand, often suffer from loose structures, low automation, large fluctuations in immersion solution parameters, and low vaccine utilization efficiency. Therefore, there is an urgent need for a compact, controllable, and stable continuous immersion inoculation device. Utility Model Content

[0003] The purpose of this invention is to provide a continuous immersion inoculation device for fish vaccines based on the Archimedes screw principle. By rotating the screw, the fish in the compartment are evenly immersed in the vaccine soaking solution, which improves the inoculation efficiency, reduces errors caused by human factors and batches, recycles the vaccine soaking solution, avoids the huddling of inoculated fish and stress reactions, maintains key inoculation parameters such as vaccine concentration, dissolved oxygen level, temperature and pH in the vaccine soaking solution, and monitors the damage to the fish, thus ensuring the health of the inoculated fish in all aspects.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides an Archimedes screw continuous immersion inoculation device for fish vaccines, comprising: a fish feeding system, a vaccine immersion solution delivery system, an Archimedes screw continuous immersion inoculation system, a vaccine immersion solution circulation and recovery system, a movable screw frame, and a drive motor housing.

[0006] The fish delivery system includes an inclined fish delivery slide and a slide support, wherein the fish delivery slide is mounted on the frame via the slide support.

[0007] The vaccine soaking solution delivery system includes a polyvinyl chloride delivery pipeline and an infusion pump. The infusion pump draws vaccine soaking solution from the vaccine soaking solution preparation tank and pumps the vaccine soaking solution onto the fish delivery slide through the delivery pipeline. The fish, along with the fish, enter the Archimedes screw soaking inoculation system from the fish delivery slide.

[0008] The Archimedes screw immersion inoculation system includes a horizontal Archimedes screw, an oxygenation shaft for the immersion inoculation system, and a camera. The length-to-diameter ratio of the horizontal Archimedes screw is 4:1. Spiral blades are arranged along the Archimedes spiral line on the inner wall of the screw, dividing the interior of the screw into multiple compartments. The vaccine immersion solution in each compartment is independent and does not affect each other. Each compartment moves forward as the screw rotates. Multiple equally spaced oxygenation holes are opened on the surface of the hollow oxygenation shaft. The screw wall is made of transparent PVC, and the rest of the screw is made of 316L stainless steel. The camera is located at the head of the screw. The transparent material of the screw wall facilitates observation and identification of the damage to the fish inside.

[0009] The vaccine soaking solution recycling system includes a fish liquid separation plate, a separation plate support, and a vaccine soaking solution recycling tank. The fish liquid separation plate and the separation plate support are mounted on the frame via corner brackets, and the vaccine soaking solution recycling tank is installed in the frame interlayer.

[0010] The movable screw frame includes casters and a mezzanine. The casters are mounted on the bottom of the frame; the mezzanine is equipped with a vaccine soaking solution recovery tank.

[0011] The drive motor housing includes a motor housing shell, a bearing housing at the tail end of the screw return oxygen pump shaft, and a drive motor. The drive motor drives the oxygen pump shaft via gears.

[0012] The movable frame has four casters at the bottom and a recycling trough embedded in the interlayer.

[0013] Furthermore, the fish delivery system has baffles of a certain height on both sides of the fish delivery slide to prevent the fish from jumping out.

[0014] Furthermore, the screw shaft is connected to the dissolved oxygen cone via a pipe, and oxygen passage holes with a diameter of less than 2 mm are evenly drilled on the shaft with equal spacing between the holes.

[0015] Furthermore, the Archimedes screw tube wall, helical blades, and oxygenating shaft are assembled together and rotate together. The screw speed is adjustable from 1 to 10 rpm and is driven by a stepper motor.

[0016] Furthermore, the Archimedes screw head camera is mounted on the head bearing seat bracket of the oxygenation shaft, and the head bearing seat is mounted on the frame below the fish delivery system via the bearing seat bracket.

[0017] Furthermore, the screw head is provided with a baffle that is higher than the highest liquid level inside the screw, occupying 1 / 4 of the outer diameter, to prevent the vaccine soaking solution from leaking out;

[0018] Furthermore, the vaccine soaking solution recovery tank is equipped with a conveying and recovery pipeline leading to the vaccine soaking solution preparation tank.

[0019] Furthermore, the frame has a drain outlet above the vaccine soaking solution recovery tank, which has the same projected area as the fish liquid separation plate on the frame.

[0020] Furthermore, the motor housing is equipped with a bracket, which is connected to the support via corner brackets.

[0021] Furthermore, the surface of the fish liquid separation plate is coated with a Teflon coating and tilted at an angle of 40°.

[0022] This invention provides a continuous immersion inoculation device for fish vaccines based on the Archimedes screw principle. The rotating screw propels fish within a compartment to be evenly immersed in the vaccine solution. The horizontal screw design improves space utilization and inoculation efficiency, reducing errors caused by human factors and batch variations. A vaccine solution recycling system recycles the solution during inoculation, lowering overall system operating costs. The screw compartment design prevents fish from crowding together, reducing stress. An oxygenation shaft provides a fully automatic oxygen supply system to maintain optimal dissolved oxygen levels in the vaccine solution. A camera monitors fish for damage, ensuring overall fish health. This system features a compact design, ease of maintenance, and good scalability. Functions can be adjusted or upgraded as needed, providing a highly efficient, precise, and low-damage continuous immersion inoculation solution for fish vaccines. It is suitable for various aquaculture animals, including fish, and has promising market application prospects. Attached Figure Description

[0030] The present invention will be described below with reference to the accompanying drawings. The specific embodiments described below are only for illustration and explanation of the present invention and are not limited to these embodiments.

[0031] like Figure 1-6 As shown, the device includes the following components: a fish delivery system 11, a vaccine soaking solution delivery system 10, an Archimedes screw soaking inoculation system, a vaccine soaking solution circulation and recovery system 6, a movable screw frame 9, and a drive motor housing 1.

[0032] like Figure 5 As shown, the fish delivery system includes a fish delivery slide 23 and a slide support 24. The fish delivery slide is an inclined channel with a height difference of 30cm, which is fixed to the top of the frame 9 by the slide support 24. The slide outlet is aligned with the Archimedes screw inlet to guide the fish into the screw compartment 4. Vertical baffles with a height of 10-15cm are provided on both sides of the fish delivery slide 23 to prevent the fish from slipping in the slide.

[0033] like Figure 4 As shown, the vaccine soaking solution delivery system includes an infusion pipeline and an infusion pump 20. The infusion pump 20 is connected to the vaccine soaking solution preparation tank through the inlet 22, and the outlet 21 extends through the pipeline to the top of the fish delivery slide 23, so that the vaccine soaking solution is evenly sprayed into the slide, and the fish body and the vaccine soaking solution are mixed and then enter the screw system.

[0034] like Figure 1As shown, the Archimedes screw continuous immersion inoculation system includes: a horizontal Archimedes screw with a length of 2m and an inner wall diameter of 0.5m. Spiral blades 3 are welded along the Archimedes spiral line on the inner wall of the screw, dividing the screw interior into 8 independent compartments 4. Each compartment can hold 10L of vaccine immersion solution containing fish. The oxygenation shaft 2 of the immersion inoculation system is a hollow shaft with a length of 2.25m, connected to an external dissolved oxygen cone via a pipe. Oxygen venting holes with a diameter less than 2mm are evenly distributed on the shaft surface, with a hole spacing of 5cm. The dissolved oxygen cone adjusts the oxygen pressure to ensure a suitable dissolved oxygen concentration in the vaccine immersion solution. Oxygen is introduced into the shaft, and oxygen venting holes are evenly distributed on the shaft surface, releasing oxygen into the vaccine immersion solution through the holes. The spiral blades 3 and the oxygenation shaft 2 are integral parts, assembled via an Archimedes spiral keyway on the inner wall of the screw wall 5, and driven synchronously by a drive motor 15.

[0035] like Figure 6 As shown, the camera 26 is fixed on the head bearing seat bracket 12, and the bracket is connected to the frame 9 below the fish delivery system by bolts. The camera's field of view is facing the transparent screw wall 5, capturing images of the fish in the compartment in real time.

[0036] like Figure 3 , Figure 5 As shown, the vaccine soaking solution recycling system includes a fish liquid separation plate 1 and a separation plate support 18. The separation plate 18 is a drain plate with a 40cm height difference, and is obliquely installed at the tail of the frame 9 via a 36cm high separation plate support. It is fixed to the frame by corner brackets 19 and is used to separate the fish body from the vaccine soaking solution. The vaccine soaking solution recycling tank 7 is 1m long, 1m wide, and 0.3m deep, located in the frame interlayer. Its bottom is connected to the vaccine soaking solution preparation tank via a PVC pipe. A one-way valve is installed in the pipe to prevent liquid backflow. The recycled solution is treated in the vaccine soaking solution preparation tank and then recycled. The frame 9 has a 550mm long and 510mm wide drain outlet at the top of the vaccine soaking solution recycling tank 7. The area of ​​the drain outlet is consistent with the projected area of ​​the fish liquid separation plate 17 on the surface of the frame, ensuring that all the separated vaccine soaking solution flows into the recycling tank.

[0037] like Figure 1 As shown, the movable screw frame 9 includes casters 8, installed at the four corners of the bottom of the frame, enabling the device to move and be positioned. A vaccine soaking solution recovery tank 7 is embedded within the frame's interlayer. The tank is connected to the vaccine soaking solution preparation tank via pipes, forming a vaccine soaking solution circulation and recovery system.

[0038] like Figure 2 As shown, the drive motor 15 in the drive motor box is a stepper motor with a speed of 25 rpm, which drives the reduction gear 16. The reduction gear 16 drives the gear on the shaft to drive the oxygen pumping shaft 2 to rotate. The tail bearing seat 14 and the head bearing seat 25 are respectively fixed by brackets to ensure stable operation of the shaft.
