Description

Technical Field

[0001] This invention relates to the field of rapeseed breeding technology, and in particular to a disinfection and soaking treatment device for rapeseed breeding. Background Technology

[0002] Currently, warm water soaking is a commonly used physical disinfection method in rapeseed breeding. The principle is to soak rapeseed seeds in warm water (50-54℃) for 20 minutes, effectively killing pathogens such as downy mildew and white rust on the seed surface. This method requires precise temperature control; too low a temperature will result in insufficient sterilization, while too high a temperature will damage the seed embryo and affect germination rate. In practice, boiling water and cool water are usually mixed in a 2:1 ratio. Once the temperature is suitable, the seeds are immediately immersed in the mixture, and continuous stirring is maintained to ensure a uniform water temperature.

[0003] However, existing hot water soaking methods for rapeseed have the following technical problems: rapeseed seeds are small and lightweight, and when placed in water in a dry state, a large number of seeds will float on the surface and accumulate, resulting in insufficient contact between the seeds and hot water, low soaking efficiency, and poor uniformity. To solve this problem, existing technologies usually use mechanical stirring devices (such as stirring paddles) to agitate the water and force the seeds to sink.

[0004] However, the blades of existing mechanical agitators collide with the seeds during rotation, causing physical damage to the seeds. In particular, the radicle of rapeseed seeds is fragile, and the collision can easily lead to a decrease in germination rate. Summary of the Invention

[0005] The purpose of this invention is to provide a disinfection and soaking treatment device for rapeseed breeding, so as to solve the technical problem that the blades of mechanical agitators collide with the seeds during rotation, causing physical damage to the seeds.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solution: a disinfection and soaking treatment device for rapeseed breeding, comprising a tank, a vertical pipe, a connecting pipe, and a pump; the top of the tank is provided with a feeding port, and the bottom of the tank is provided with a discharge port; the lower end of the vertical pipe is provided through the bottom of the tank, and the upper end of the vertical pipe is provided with a water outlet, the water outlet being higher than the maximum liquid level during the soaking operation inside the tank; one end of the connecting pipe is connected to the vertical pipe, and the other end of the connecting pipe is connected to a position on the side wall of the tank that is lower than the maximum liquid level; the pump is provided on the connecting pipe and is used to discharge the water in the tank back into the tank through the water outlet, thereby pressing the seeds accumulated at the maximum liquid level into the water.

[0007] Preferably, it also includes a rotating nozzle, which is disposed at the water outlet and is used to spray the water discharged from the water outlet more evenly and obliquely downward.

[0008] Preferably, an umbrella-shaped protective cover is provided above the rotating nozzle.

[0009] Preferably, a filter screen is provided at one end of the connecting pipe that communicates with the tank body.

[0010] Preferably, the connecting pipe is also connected to a water inlet pipe, which is used to backwash the filter screen after water is introduced through the water inlet pipe.

[0011] Preferably, a waste outlet is provided on the side wall of the tank at a position higher than the maximum liquid level; after the water inlet pipe is started, the waste that still floats on the surface of the water after soaking is discharged from the waste outlet.

[0012] Preferably, the side wall of the tank is provided with an air inlet, and the air inlet is used to make the water and seeds in the tank rotate.

[0013] Preferably, there are 2-4 air inlets, and each air inlet is arranged at equal intervals along the circumference of the tank.

[0014] Preferably, the angle between the top view projection of the air inlet and the direction of the tank diameter is 75-85°, and the angle between the front view projection of the air inlet and the horizontal line is 75-85°.

[0015] Compared with existing technologies, the advantages of this application are as follows: First, warm water is injected into the tank through the feeding port, and then rapeseed seeds are added through the feeding port. After the pump is started, the water in the tank is sequentially drawn into the connecting pipe and the vertical pipe, and finally discharged back into the tank through the outlet. Because the height of the outlet is higher than the maximum liquid level in the tank during the soaking operation, the water discharged from the outlet can push the seeds into the water, allowing them to quickly submerge below the water surface, thereby improving soaking efficiency. Simultaneously, it avoids the rapeseed seeds accumulating above the water surface for a long time, which helps improve the uniformity of soaking. Otherwise, if the rapeseed seeds accumulate above the water surface for a long time, some seeds will not have sufficient contact with the warm water, failing to achieve the expected disinfection effect.

[0016] Compared with traditional mechanical stirring, this application relies on water flow to press the seeds down, eliminating direct collision between the stirring blades and the seeds, effectively avoiding physical damage to the seeds and ensuring the germination rate.

[0020] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1 Reference Figure 1 One embodiment of this application provides a disinfection and soaking treatment device for rapeseed breeding, including a tank 1. The tank 1 has a cylindrical structure and is preferably made of stainless steel, which has good corrosion resistance. A feeding port 11 is provided at the top of the tank 1 for adding rapeseed seeds to be treated, or for adding warm water. A discharge port 12 is provided at the bottom of the tank 1, and a valve is installed on the discharge port 12 for discharging the rapeseed seeds and remaining water after soaking.

[0023] To address the problem of rapeseed damage caused by mechanical stirring in existing technologies, this application improves upon this method by installing a vertical pipe 2 at the center of the bottom of the tank 1. The lower end of the vertical pipe 2 passes through and is sealed to the bottom plate of the tank 1, while the upper end extends upwards into the interior space of the tank 1. The top of the vertical pipe 2 forms a water outlet, designed to be higher than the maximum liquid level in the tank 1 during normal seed soaking. The maximum liquid level refers to the highest height the water surface or rapeseed seeds can reach after warm water is injected. This design, with the water outlet above the liquid surface, ensures that the water jet from the outlet impacts the rapeseed seeds floating on the surface from above, thus pushing them into the water.

[0024] A connecting pipe 3 is installed on the outside of the tank 1. One end of the connecting pipe 3 is connected to the lower part of the vertical pipe 2 (near the bottom of the tank 1), and the other end is connected to the side wall of the tank 1. This connection point is below the maximum liquid level and is usually located in the lower middle part of the side wall of the tank 1 to ensure the intake of intermediate water. A pump body 4 is installed on the connecting pipe 3. The pump body 4 is used to drive the liquid to circulate in the pipeline, so that the water in the tank 1 can be sequentially drawn into the connecting pipe 3 and the vertical pipe 2, and finally discharged back into the tank 1 from the outlet. The pump body 4 can be a temperature-resistant centrifugal pump, which can adapt to hot water environments of 50-54℃.

[0025] A filter screen is installed at the end of the connecting pipe 3 that connects to the side wall of the tank 1. The mesh size of the filter screen is selected according to the size of the rapeseed seeds, which is prior art and will not be described in detail in this application. The filter screen can effectively prevent rapeseed seeds or larger impurities from being sucked into the connecting pipe 3 and the pump body 4, avoiding blockage and damage. The filter screen can adopt a detachable structure, such as a snap-fit, for easy regular cleaning or replacement.

[0026] A water inlet pipe 31 can also be connected to the connecting pipe 3. The water inlet pipe 31 is equipped with an inlet valve, and the other end is connected to an external water source. The water inlet pipe 31 has three functions: firstly, it can introduce warm water into the tank 1; secondly, after soaking, water can be added to the tank 1 through the water inlet pipe 31. The connecting pipe 3 is equipped with a control valve; when the control valve is closed, the water entering from the water inlet pipe 31 flows into the tank 1 through the filter screen, thus achieving backwashing of the filter screen; thirdly, it can also be used in conjunction with a waste outlet 13 with a valve located above the maximum liquid level. As the backwash water continuously enters the tank 1, the water level in the tank 1 rises. Opening the valve at the waste outlet 13 allows inferior seeds floating on the water surface to be discharged through the waste outlet 13 with the water. For example, a waste outlet 13 can be located on the side wall of the tank 1, approximately 5-10 cm above the maximum liquid level. A waste valve is installed on the waste outlet 13. The waste outlet 13 is used to automatically discharge impurities (such as broken seed coats, dust, and floating inferior seeds) floating on the water surface by raising the liquid level after soaking, without the need for manual retrieval.

[0027] To further enhance the water's penetration effect on the rapeseed seeds, a rotating nozzle is installed at the outlet at the top of the vertical pipe 2. The rotating nozzle has multiple downward-sloping nozzles. When water is ejected at high speed from these nozzles, the resulting reaction force drives the nozzle to rotate around its vertical axis. This transforms the water flow from a single-direction jet into a continuously rotating, umbrella-shaped water curtain that evenly covers the entire liquid surface. The rotation speed of the rotating nozzle can be experimentally adjusted using water pressure and nozzle angle; this application does not impose any limitations on this adjustment.

[0028] To prevent rapeseed seeds from entering the vertical pipe 2 or the rotating nozzle during feeding, an umbrella-shaped protective cover 5 is installed directly above the rotating nozzle. The edge of the protective cover extends to the periphery of the rotating nozzle. The protective cover is fixed to the vertical pipe 2 by 2-3 support brackets, ensuring it does not contact the rotating nozzle. When seeds are fed from the feeding port 11, they fall under gravity, first impacting the inclined surface of the protective cover, and then sliding down the inclined surface to the liquid surface, rather than directly hitting the rotating nozzle or entering the interior of the vertical pipe 2 if no rotating nozzle is installed.

[0029] The bottom of tank 1 is also equipped with three support legs to stably support the entire device and make it stable.

[0030] The working process of this embodiment is as follows (taking warm water soaking as an example): First, inject warm water at 50-54℃ into tank 1 to the set liquid level, usually about two-thirds of the height of tank 1. Then, close the water inlet valve, open the feeding port 11, and put the rapeseed seeds into tank 1. The seeds fall under the action of gravity, and after encountering the umbrella-shaped protective cover 5, slide down its inclined surface to the liquid surface. Next, start pump 4, pump 4 draws water from the lower part of the side wall of tank 1, the water is filtered through the filter screen, enters the vertical pipe 2 through the connecting pipe 3, and then sprays upward from the rotating nozzle. Since the rotating nozzle is higher than the liquid surface, the sprayed water flow forms a downward impact force, pressing the seeds floating on the liquid surface into the water. At the same time, as the water is continuously drawn in, a downward circulation is formed in tank 1, and the seeds are repeatedly pressed into the water with the water flow, making full contact with the hot water. The rotation of the rotating nozzle makes the water flow evenly cover the entire liquid surface, ensuring that all seeds can be effectively pressed in.

[0031] After soaking, first open the waste valve and the water inlet valve, close the control valve on connecting pipe 3, and inject water into tank 1. The water backwashes the filter screen and causes the liquid level to rise gradually. At this time, impurities floating on the water surface rise with the liquid level and automatically overflow when they reach waste outlet 13, flowing into the waste liquid collection container or being discharged directly. Continue injecting water until no obvious impurities overflow. Then, close the waste valve and the water inlet valve, open the valve of outlet 12, and discharge the seeds and remaining water together. Collect the seeds for the next process.

[0032] Example 2 Combination Figure 2 This embodiment adds a pneumatically assisted swirling function to the first embodiment to further improve the uniformity and efficiency of seed soaking. Specifically, 2-4 air inlets 14 are opened on the side wall of the tank 1, with the height of the air inlets 14 suitable for the maximum liquid level. In this embodiment, the number of air inlets 14 is preferably 3, arranged at equal intervals along the circumference of the tank 1, i.e., the angle between adjacent air inlets 14 is 120 degrees. Each air inlet 14 is connected to an external air source, such as a small air compressor or air pump, through a pipeline to provide stable compressed air or inert gas. By introducing gas into the tank 1, the gas will drive the water inside the tank 1 to rotate, thereby accelerating the mixing efficiency between the rapeseed and the water, thus achieving the same soaking effect in a shorter time, or obtaining better uniformity within the same soaking time.

[0033] It should be emphasized that the direction in which the gas is introduced to cause the water to rotate is preferably opposite to the rotation direction of the rotating nozzle, which helps to accelerate the mixing efficiency between rapeseed and water.

[0034] However, after the water rotates, the rapeseed seeds are subjected to centrifugal force, which makes them tend to gather towards the inner wall of the tank 1. This can affect the mixing effect between the rapeseed seeds and the water, and also cause the rapeseed seeds to collide and rub against the inner wall of the tank 1, thus damaging the rapeseed seeds.

[0035] From a top-down view, the angle between the centerline of the air inlet 14 and the diameter of the tank 1 is 80 degrees (it can be selected within the range of 75-85 degrees). This means that the air intake direction is not strictly tangential, but slightly biased towards the diameter, though still predominantly tangential. When gas enters the tank 1 from the air inlet 14, due to the near-tangential direction from a top-down view, the gas pushes the water to generate a rotating flow. The rotating water flow carries the seeds, improving the mixing efficiency between the seeds and the water, thus achieving the same soaking effect in a shorter time, or obtaining better uniformity within the same soaking time. Simultaneously, because the air intake direction is slightly biased towards the diameter, it can push the rapeseed seeds near the inner wall of the tank 1 towards the center of the tank 1, preventing direct collision and friction between the rapeseed seeds and the inner wall of the tank 1, thereby protecting the rapeseed seeds from damage.

[0036] Viewed from the front, the angle between the centerline of the air inlet 14 and the horizontal line is also set to 80 degrees (it can also be selected within the range of 75-85 degrees), meaning the airflow enters the water body obliquely downwards, rather than horizontally. Because the air inlet 14 is obliquely downwards, the airflow entering the water body generates a downward component force. This downward component force acts on the water body, and consequently on the seeds suspended in the water. When the seeds move towards the tank wall under the action of centrifugal force, this downward airflow component force pushes the seeds near the tank wall downwards, causing them to escape the centrifugal zone near the tank wall and be carried back to the center area of ​​the tank 1 by the circulating water flow below. This effectively avoids direct collision between the seeds and the tank wall, eliminating the risk of seed damage caused by centrifugal force.

[0037] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
