Description

Technical Field

[0001] This utility model relates to the field of pathogenic nematode concentration technology, and in particular to an insect pathogenic nematode concentration device. Background Technology

[0002] Entomopathogenic nematodes are a type of nematode that parasitizes insects, causing disease and death. They play an important role in biological control, primarily by releasing symbiotic bacteria. Once the nematodes invade an insect's body, the symbiotic bacteria they carry rapidly multiply in the insect's hemocoel, producing toxins that damage the insect's immune system and organs, leading to death. Entomogenic nematode concentration is mainly used to increase the nematode concentration in entomopathogenic nematode preparations.

[0003] Common concentration methods include centrifugal concentration and evaporative concentration. Centrifugal concentration uses the centrifugal force generated by a centrifuge to rapidly precipitate entomopathogenic nematodes in a centrifuge tube, separating them from the supernatant to achieve concentration. However, the strong centrifugal force generated during high-speed rotation can easily cause physical damage to entomopathogenic nematodes, leading to rupture of the nematode's body surface and damage to its internal organs, greatly reducing the nematode's survival rate and infectivity. While evaporative concentration reduces the amount of suspension, causing less damage to the nematodes, the suitable temperature range for nematode survival is narrow. Excessively high temperatures can easily lead to nematode death. Therefore, evaporative concentration cannot use excessively high temperatures for heating, resulting in a very slow evaporation rate and affecting concentration efficiency.

[0004] Based on the above situation, we propose an insect pathogenic nematode concentration device to solve the above problems. Utility Model Content

[0005] This invention provides a device for concentrating entomopathogenic nematodes to solve the problems existing in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] An insect pathogen nematode concentration device includes a container, a heating mechanism, a liquid level sensor, and a controller. The container has at least one opening and closing component inside. When at least one of the opening and closing components is closed, the container is divided into at least two storage spaces to quickly establish a high vapor pressure in the early stage of concentration and accelerate the evaporation initiation rate. The heating mechanism is located inside the storage space and is used to heat and evaporate the suspension in the storage space. The liquid level sensor is installed inside the storage space and is used to detect the liquid level of the suspension in the storage space. The controller controls the opening and closing of the opening and closing component based on the liquid level signal from the liquid level sensor to adapt to the space requirements of the container's internal space at different concentration stages.

[0008] Preferably, the opening and closing component includes two sealing plates that are disposed opposite to each other and slidably connected inside the container, and the sealing plates are driven by a telescopic component installed on the inner wall of the container.

[0009] Preferably, it also includes an alarm device electrically connected to the controller, which controls the alarm device to issue an alarm when the controller receives a signal from the level sensor indicating that the level of the suspension in the container space is below a set threshold.

[0010] Preferably, the mounting space is equipped with a constant temperature lamp.

[0011] Preferably, the container is equipped with a blower, and the output end of the blower is located inside the container.

[0012] Preferably, the container is detachably connected to a sealing cap, and the sealing cap has an air vent.

[0013] The beneficial effects of this invention are as follows: by dividing the container into multiple small holding spaces through the opening and closing parts, it is conducive to quickly establishing high vapor pressure in the early stage of concentration and accelerating the evaporation initiation speed. As evaporation proceeds, the suspension continuously decreases. Opening the opening and closing parts to expand the space can provide a more suitable evaporation environment for the remaining suspension, avoid the problems of local overheating and excessively high concentration, and ensure the survival rate and activity of nematodes during the concentration process.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-4 As shown, the entomopathogenic nematode concentration device includes a container 1, a heating mechanism 3, a liquid level sensor 4, and a controller 5. At least one opening / closing element 2 is provided inside the container 1. When at least one opening / closing element 2 is closed, the container 1 is divided into at least two storage spaces 11. The heating mechanism 3, which can be an electric heating wire or similar device, is installed inside the storage space 11, such as inside the opening / closing element 2, to heat the suspension and cause it to evaporate. This is used to quickly establish a high vapor pressure in the early stages of concentration and accelerate the evaporation initiation rate. For example, taking one opening / closing element 2 as an example, when the opening / closing element 2 is closed, the container 1 is divided into two smaller and independent storage spaces. 11. When the suspension is poured into the container 1, the suspension will be located in the upper container space 11. During the initial concentration, the evaporation space of the suspension is reduced, so that the concentration of nematodes per unit volume is relatively high. At the same time, the vapor pressure on the liquid surface is increased, thereby accelerating the evaporation rate of the suspension. In addition, a temperature sensor 12 can be installed in the container space 11 to detect the temperature of the heated suspension, so that the heating mechanism 3 maintains the heating temperature at about 25°C. This ensures that the suspension has suitable temperature conditions for evaporation, and avoids damage to the entomopathogenic nematodes caused by excessively high or low temperatures, thus minimizing the impact on their activity during the concentration process.

[0022] Furthermore, a level sensor 4 is also provided in the container space 11 to detect the level of the suspension in the container space 11. For ease of understanding, the container space 11 is still described as two. If the level sensor 4 in the upper container space 11 detects that the suspension is lower than the preset threshold, it indicates that the remaining amount of suspension has reached a certain state. At this time, the controller 5 controls the opening and closing plate to open, so that the suspension in the upper container space 11 falls into the lower container space 11. At this time, the space in the container 1 increases, which can provide a more suitable evaporation environment for the remaining suspension, avoid the problems of local overheating and excessive concentration, and ensure the survival rate and activity of nematodes during the concentration process.

[0023] Reference Figure 3As shown, the opening and closing component 2 further includes two sealing plates 21 that are arranged opposite to each other and slidably connected inside the container 1. The sealing plates 21 are driven by a telescopic component 22 installed on the inner wall of the container 1. When the telescopic component 22 drives the two sealing plates 21 to move relative to each other and come into close contact, the two plates are closed. At this time, the suspension in the upper container space 11 will not fall to the lower side. In order to improve the sealing performance, a sealing gasket or the like can be provided on the opposite side of the sealing plates 21. The telescopic component 22 can be driven by an electric telescopic rod or the like.

[0024] Reference Figure 1 as well as Figure 4 As shown, further, it also includes an alarm element 6 electrically connected to the controller 5. The alarm element can be an audible / visual warning. When the controller 5 receives a signal from the level sensor 4 indicating that the level of the suspension in the container space 11 is below a set threshold, it controls the alarm element 6 to issue an alarm. When the level sensor 4 located above detects that the level is below the set value, in addition to opening the opening and closing plate through the controller 5, it can also issue an alarm through the alarm element 6 to remind personnel. When the level sensor 4 in the container space 11 at the bottom detects that the level is below the set value, the controller 5 controls the alarm element 6 to issue a different alarm prompt than before, indicating that the concentration work has been completed at this time, so that personnel can distinguish between different concentration stages.

[0025] Reference Figures 3-4 As shown, in order to improve the heating uniformity of the suspension, a constant temperature lamp 7 is provided in the container space 11. The heating mechanism 3 provides the main heat source for the suspension. At the same time, a constant temperature lamp 7 is provided on the side of the container space 11 to assist in heating and adjust the temperature uniformity. The power of the heating element and the constant temperature lamp 7 can be flexibly adjusted according to different concentration stages and liquid volume.

[0026] Reference Figure 2 As shown, the container 1 is further equipped with a blower 8, the output end of which is located inside the container 1. The blower 8 can create air convection inside the container, allowing the evaporated water vapor to be carried away more quickly, preventing water vapor from accumulating inside the container 1, thereby improving evaporation efficiency. In addition, the blower 8 can promote airflow, allowing heat to be distributed more evenly inside the container 1, preventing insect pathogenic nematodes from being damaged by local overheating, and also helping to maintain the stability of the overall temperature, ensuring that concentration is carried out at a suitable temperature.

[0027] Reference Figure 1As shown, a sealing cap 9 is detachably connected to the container 1, and the sealing cap 9 has a vent 91. The sealing cap 9 can be opened when adding the suspension, and closed when concentrating. On the one hand, this prevents external dust, impurities, microorganisms, etc. from entering the container, thus avoiding contamination of the entomopathogenic nematode suspension and ensuring the quality of the concentrated suspension. On the other hand, the sealing cap 9 ensures the airtightness of the container 1, which helps to maintain stable internal vapor pressure and temperature during the concentration process. The vent 91 allows steam to escape, preventing excessive pressure inside the container 1 and making the concentration process more stable and controllable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
