Description

Technical Field

[0001] The present invention relates to the technical field of biotechnology, and in particular to a zero-mass jet device for laser-breaking plant spores. Background Art

[0002] The laser wall-breaking process first requires the preparation of a suspension consisting of spores and pure water. During this preparation, it is important to ensure that the suspension maintains the Newtonian morphology of the fluid. Newtonian fluids are low-viscosity fluids that easily deform under stress, with shear stress proportional to the rate of deformation. However, to achieve relatively high wall-breaking efficiency, the mass percentage of spores to pure water is typically adjusted to the critical value for Newtonian fluids. The water curtain laser wall-breaking process line features multiple light-receiving zones, each equipped with multiple light receptors and corresponding lasers. When the fluid flows through the glass target area of the first light receptor, it is ablated by the laser. Some of the broken spores and their contents dissolve in the water, forming a suspension. The viscosity of the suspension containing the spores increases, gradually losing its Newtonian morphology. Bounded fluid systems can flow in three states: laminar, transitional, and turbulent. Viscosity is a key factor in determining these three states. As material viscosity increases, the fluid forms a steady laminar flow, severely impacting the efficiency and rate of spore wall rupture in subsequent photoreceptors. The glass target, a crucial component of the photoreceptor, transforms the incoming fluid into a thin, flat, water-curtain-like structure within the narrow glass target. This fluid receives laser irradiation and converts the laser's light energy into heat, burning the spore shells. Maintaining a consistent level of turbulence within the glass target to increase spore replacement efficiency is crucial for improving spore wall rupture efficiency and rate.

[0003] The target area of the glass target area that receives laser scanning and is the main component of the light energy receiver in the water curtain process of laser breaking plant spores is a nearly closed, thin, flat, narrow rectangular hollow hexahedron area. If the rapid replacement of spores in the material fluid is to be achieved in the narrow hexahedron area, passive control methods such as changing the flow channel to cause vortices to form turbulence are difficult to achieve the best control effect, especially since the viscosity of the fluid gradually increases after some spores are broken, it is more difficult to form turbulence and laminar flow appears. Laminar flow is the stratified flow of the fluid with slip motion. The serious laminar flow phenomenon will lead to unsatisfactory laser wall breaking effect of the first and subsequent light energy receivers in the work station area, and will cause the flow layer facing the laser irradiation in the glass target area to be carbonized due to excessive irradiation. Summary of the Invention

[0004] The object of the present invention is to provide a zero-mass jet device for laser breaking plant spores, so as to solve the problems raised in the above-mentioned background technology.

The outer wall of the upper end of the material table is provided with a bottom plate. The jet receiver further includes a gantry, a panel, a flow channel plate, a function plate and a back plate.

[0006] When using the zero-mass jet device for laser breaking plant spores in this technical solution, the material fluid is input from the feed hole of the jet receiver, flows upward through the target of the jet receiver in the fluid channel with the panel and the back plate as the channel walls. The laser scanning area is set above the elliptical turbulent flow generating groove and below the discharge hole. The material fluid is irradiated by the laser in the target area scanned by the laser to break the wall, and then is output from the discharge hole to the finished product recovery pipeline. The gas and foam generated when breaking the spores enter the condensation recovery channel through the exhaust hole. The magnetic field of the first permanent magnet and the magnetic field of the jet induction vibration membrane satisfy the principle of magnetic force vector superposition. The rapidly alternating magnetic field causes the jet induction vibration membrane to oscillate, and the intensity and frequency of this oscillation can be adjusted according to the use position of the rim and the working frequency of the right-angle motor, so as to cause the turbulent flow generated in the turbulent flow generating groove to generate a strong disturbance on the horizontal plane of the main fluid flowing vertically upward in the flow channel. The disturbance on this horizontal plane and the vertical flow cause a vortex ring, thereby generating turbulence in the flow field within the target laser scanning area.

[0007] Preferably, the jet generator further includes a transmission mechanism, a coupling and a right-angle motor. The transmission mechanism is installed on the upper end of the bottom plate, and the right-angle motor is connected to the transmission mechanism through a shock absorption mechanism.

[0015] Preferably, the panel is a glass plate that receives laser irradiation. The panel faces the laser lens, and then is arranged and combined in the order of the flow channel plate, the function plate, and the back plate, forming the panel and the back plate as the channel walls, and the material fluid flows through the channel between them.

[0016] Preferably, small holes are respectively opened at the same position on the function plate and the back plate, a feed hole is opened at the lower part, and a discharge hole and an exhaust hole are opened at the upper part.

The permanent magnet is surrounded by a non-toxic soft plastic material and insulated from the material fluid. There is an installation screw hole at the center of the vibration membrane. The planar dimension of the area of the jet induction vibration membrane is not greater than 1 / 2 of the planar dimension of the generation groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: By providing a jet device and a jet receiver, the present invention achieves the effect of improving the cell wall breaking efficiency. The jet generator causes the jet induction vibration film inside the jet receiver to continuously oscillate in the turbulent flow generating groove in the target, resulting in the generation of turbulent flow in the material fluid in the turbulent flow generating groove. This turbulent flow interacts and couples with the main material fluid in the target to generate a vortex ring, leading to the formation of a turbulent flow field in the target of the jet receiver. When the material fluid flows through the laser irradiation target area in the jet receiver, it is irradiated by the laser and the spore cell walls are broken. This enables the material fluid to maintain a certain degree of turbulence to increase the replacement rate of spores, thereby improving the spore cell wall breaking efficiency and the breaking rate.
