Description

Technical Field

[0001] The invention relates to the field of aquatic product transportation, and in particular to a series-type nanometer oxygenator for aquatic product transportation. Background Art

[0002] When transporting aquatic products, they are often limited by the volume of the vehicle compartment. High-density packaging is often used. A relatively small space can hold more aquatic products. Conventional oxygen pumps have large bubbles that stay in the water for a short time and release quickly. The amount of oxygen that can be dissolved in the water is limited, and the crowded environment causes a large number of aquatic products to die of lack of oxygen.

[0003] Micro bubbles smaller than 50 microns will stay in the water for a long time. The diameter of the micro bubbles is small, so they can increase the contact area between gas and liquid and increase the oxygen content of gas in liquid, which is very beneficial for long-term aerobic respiration of aquatic products and can increase the amount of dissolved oxygen in the water (seawater) of aquatic products or fresh fish transport vehicles. To ensure the transportation of aquatic products, the supply of oxygen is required. The method of obtaining micro-nano bubbles in the prior art actually uses a water pump. In order to ensure a higher flow rate, the water pump used is relatively large, and the overall bubble generating device is relatively bulky, which undoubtedly limits the application of nano oxygenation in the transportation of aquatic products. Summary of the invention

[0004] Therefore, the present invention is made in view of the above problems. The purpose of the present invention is to provide a series-type aquatic transport nano-aerator, which is achieved through the following technical solutions:

[0005] A serial aquatic product transport nano-aerator, comprising: a first water pump, a second water pump, a water inlet pipe, an air inlet pipe, a collision connection part, and a release pipe;

[0006] The water outlet pipe of the first water pump is connected in series with the water inlet pipe of the second water pump and is arranged in a rectangular housing;

[0007] As shown in the figure, the water inlet pipe is a Venturi structure with large ends and a reduced diameter in the middle. One end is connected to the water inlet pipe of the first water pump, and the other end is connected to the underwater part of the aquaculture tank through a pipe.

[0008] The air inlet pipe is an L-shaped tubular body, which penetrates into the reduced diameter portion of the water inlet pipe above the water inlet pipe, and the horizontal portion of the air inlet pipe is arranged at the axial position of the water inlet pipe, and is open and faces the direction of the first water pump;

[0009] The conflict connection part is arranged at the water outlet end of the second water pump, and includes: a guide gasket and a pipe;

[0010] The pipe is connected to the outlet pipe of the second water pump, and the inner hole at one end of the connecting section with the second water pump is provided with a pipe platform, and a semi-cylindrical horizontal groove is provided on the inner hole wall from the rear of the pipe platform to the other end in the axial direction of the pipe, and a plurality of annular inner ring grooves are provided at intervals on the inner hole wall in the longitudinal direction of the pipe, and the inner ring grooves interrupt the cornice formed between the horizontal grooves;

[0011] The guide gasket is composed of a plurality of cylinders with different diameters, which are concentrically arranged in a step-like shape, with a small diameter end facing the outlet pipe of the second water pump, and a large diameter end movably arranged in the pipe platform, and a plurality of injection through holes inclined toward the outer peripheral side are arranged in the center thereof, and a plurality of semicircular grooves for guiding water flow are arranged from the small diameter end surface of the guide gasket to the outer peripheral side of the large diameter end thereof, and the semicircular grooves penetrate at the outer peripheral side of the guide gasket to guide the water flow to be sprayed toward the inner wall of the pipe;

[0012] The release tube is a tubular body, one end of which is connected to the collision connection part, and the other end extends into the water of the aquaculture tank.

[0013] Preferably, the fluid passing section and power of the second water pump are 1.3 times that of the first water pump. When the first water pump and the second water pump select the same fluid passing section and power, since the processing capacity of the two pumps is the same, after the fluid is pressurized by the first water pump, it is easy for the second water pump to fail to process it in time, resulting in a bottleneck;

[0014] Preferably, the guide gasket and the pipe platform are arranged to be connected by a bearing to reduce the friction between the guide gasket and the pipe platform, and when water flows through the inclined through hole, the guide gasket is pushed to rotate.

[0015] Preferably, an annular groove is provided on the step surface of the guide gasket, so that part of the water flow is turned back through the annular groove and collides with the original water flow.

[0016] Preferably, the additional conflict connection part is between the first water pump and the second water pump, and after the first water pump is pressurized, a step-by-step bubble refinement collision treatment is performed. When the first water pump and the second water pump select the same fluid passing section and power, the flow rate of the additional conflict connection part will decrease slightly after the bubble refinement collision treatment, which is more conducive to the flow increase of the second water pump without causing a bottleneck, making the power distribution more reasonable.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention adopts a multi-pump series connection mode to replace the single pump of the prior art to obtain the micro-nano bubble mixed liquid, and the volume is significantly reduced;

[0019] 2. In the series connection mode of the present invention, the blades of each pump actually achieve a shearing effect on the gas-liquid mixed fluid, meeting the demand for high-density live aquatic production on vehicles and high oxygen density in the water.

[0020] 3. It can purify the water in the aquatic tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that it is easy for a person skilled in the art to implement these embodiments. However, the present invention may be implemented in various forms, and therefore the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, parts that are not connected to the present invention will be omitted from the accompanying drawings.

[0026] like Figure 1 As shown, a serial aquatic product transport nano-aerator comprises: a first water pump 1, a second water pump 2, a water inlet pipe 3, an air inlet pipe 4, a collision connection part 5, and a release pipe 6;

[0027] The water outlet pipe of the first water pump 1 is connected in series with the water inlet pipe of the second water pump 2 and is arranged in a rectangular housing 100;

[0028] like Figure 2 As shown, the water inlet pipe 3 is a Venturi structure with large ends and a reduced diameter in the middle, one end of which is connected to the water inlet pipe of the first water pump 1, and the other end is connected to the underwater of the aquaculture tank 101 through a pipe;

[0029] The air inlet pipe 4 is an L-shaped tubular body, which penetrates into the reduced diameter portion of the water inlet pipe 3 above the water inlet pipe 3. The horizontal portion of the air inlet pipe 4 is arranged at the axial position of the water inlet pipe 3, and is open and faces the direction of the first water pump 1.

[0030] like Figure 3 As shown, the conflict connection part 5 is arranged at the water outlet end of the second water pump 2, and includes: a guide gasket 51 and a pipe 52;

[0031] The pipe 52 is connected to the outlet pipe of the second water pump 2, and the inner hole at one end of the connecting section with the second water pump 2 is provided with a pipe stand 521. On the inner hole wall from the rear of the pipe stand 521 to the other end, a semi-cylindrical horizontal groove 523 is axially provided with the pipe 52. On the inner hole wall in the longitudinal direction of the pipe 52, a plurality of annular inner ring grooves 522 are arranged at intervals, and the inner ring grooves 522 interrupt the cornice formed between the horizontal grooves 523 and the horizontal grooves 523.

[0032] The guide gasket 51 is composed of a plurality of cylinders with different diameters, which are concentrically arranged in a step-like shape, with the small diameter end facing the outlet pipe of the second water pump 2, and the large diameter end movably arranged in the pipe platform 521, and a plurality of injection through holes 511 inclined toward the outer peripheral side are arranged in the center thereof, and a plurality of semicircular grooves 513 for guiding water flow are arranged from the small diameter end surface of the guide gasket 51 to the outer peripheral side of the large diameter end thereof, and the semicircular grooves 513 penetrate at the outer peripheral side of the guide gasket 51 to guide the water flow to be sprayed toward the inner wall of the pipe 52;

[0033] The release tube 6 is a tubular body, one end of which is connected to the collision connection part 5 and the other end of which extends into the water of the aquatic tank 101 .

[0034] like Figure 4 As shown, preferably, as an implementable embodiment, the fluid passing section and power of the second water pump 2 are 1.3 times that of the first water pump 1. When the first water pump 1 and the second water pump 2 select the same fluid passing section and power, since the processing capacity of the two pumps is the same, after the fluid is pressurized by the first water pump 1, it is easy for the second water pump 2 to fail to process it in time, resulting in a bottleneck;

[0035] Preferably, as an implementable embodiment, the guide gasket 51 and the tube platform 521 are arranged to be bearing-connected, so as to reduce the friction between the guide gasket 51 and the tube platform 521. When the water flows through the inclined through hole 511, the guide gasket 51 is pushed to rotate, thereby enhancing the turbulence and impact effect, and facilitating the refinement of the bubbles.

[0036] Preferably, as an implementable embodiment, an annular groove 512 is provided on the step surface of the guide gasket 51, so that part of the water flow is turned back through the annular groove 512 and collides with the original water flow, thereby enhancing the turbulence effect.

[0037] Preferably, as an implementable embodiment, the additional conflict connection part 5 is between the first water pump 1 and the second water pump 2, and after the first water pump 1 is pressurized, a step-by-step bubble refinement collision treatment is performed. When the first water pump 1 and the second water pump 2 select the same fluid passing section and power, the flow rate of the additional conflict connection part 5 will decrease slightly after the bubble refinement collision treatment, which is more conducive to the flow increase of the second water pump 2 without causing a bottleneck, making the power distribution more reasonable.

[0038] Working principle of the present invention:

[0039] ① The water inlet pipe 3 is placed into the aquatic box 101 through a hose, and the first water pump 1 and the second water pump 2 are turned on. The water flow is sucked into the first water pump 1. Since the water inlet pipe 3 is a Venturi structure with large ends and a reduced diameter in the middle, under the suction of the first water pump 1, the reduced diameter part of the water inlet pipe 3 generates a high-speed water flow and generates a negative pressure near the air inlet pipe 4. External air is sucked into the water inlet pipe 3 to form a preliminary gas-liquid mixture;

[0040] ② The gas-liquid mixture enters the collision connection part 5 under the boost of the first water pump 1 and the second water pump 2, and the water flow is divided into two paths. One path is sprayed to the inner wall of the tube 52 through the through hole 511, and the other path is sprayed to the inner wall of the tube 52 on the outer peripheral side of the guide gasket 51 through the semicircular groove 513. The different reflection surfaces of the inner annular groove 522 and the horizontal groove 523 form collision, reflection, and turbulence at the broken eaves, thereby refining the bubbles of the gas-liquid mixture, thereby increasing the oxygen content of the water in the aquatic box 101 during aquatic product transportation.
