Description

Technical Field

[0001] The invention relates to the field of aquaculture, and in particular to a medium-pressure ultraviolet multi-frequency shingled ultrasonic circulating water treatment device, which is used for removing parasites from circulating water in a circulating water aquaculture system. Background Art

[0002] Recirculating aquaculture is a common aquaculture method. In order to achieve sterilization and disinfection, the current recirculating aquaculture system usually needs to be equipped with water treatment devices such as curved screens, protein separators, and biological pools. However, the above-mentioned circulating water treatment devices are still unable to effectively remove parasite eggs and micro-parasites that enter the circulating water system. Once the parasites in the breeding pond break out, the entire recirculating aquaculture system will completely collapse. Therefore, how to develop a new type of circulating water treatment device that can kill and remove parasite eggs and micro-parasites in the circulating water of the recirculating aquaculture system to overcome the above-mentioned problems existing in the prior art is a direction that technicians in this field need to study. Summary of the invention

[0003] The object of the present invention is to provide a medium-pressure ultraviolet multi-frequency shingled ultrasonic circulating water treatment device, which can improve the killing and removal rate of parasite eggs and micro-parasites in circulating water in a circulating aquaculture system.

[0004] The present invention discloses a medium-pressure ultraviolet multi-frequency shingled ultrasonic circulating water treatment device, which comprises:

[0005] A circulating water pipeline, wherein one end of the circulating water pipeline is provided with a water inlet, the other end of the circulating water pipeline is provided with a water outlet, the middle section of the circulating water pipeline is provided with a straight round tube, and the tube wall of the straight round tube is made of a transparent material;

[0006] An ultrasonic device, the ultrasonic device comprising a mounting bracket, the mounting bracket being provided with a circular channel; the straight circular tube passes through the mounting bracket through the circular channel, and the straight circular tube and the circular channel are arranged in concentric circles; a plurality of ultrasonic generating devices are distributed on the inner wall of the circular channel;

[0007] A medium-pressure ultraviolet lamp column, wherein the medium-pressure ultraviolet lamp column is embedded and installed on the inner wall of the straight circular tube;

[0008] A base, the mounting bracket is fixedly mounted on the base.

[0009] By adopting this technical solution: the circulating water in the circulating aquaculture system is introduced into the circulating water pipeline through the water inlet. When the circulating water flows to the straight circular tube, the ultrasonic generator distributed on the inner wall of the circular channel outputs ultrasonic waves toward the straight circular tube, and the ultrasonic waves kill the parasite eggs and micro-parasites in the circulating water. The medium-pressure ultraviolet lamp column uses an ultraviolet lamp filled with nitrogen that can withstand a pressure of 16kg. The ultraviolet light it outputs can effectively kill the parasite eggs and micro-parasites that are severely damaged by ultrasonic waves. In addition, the killing of bacteria and the removal of harmful substances such as nitrite can be achieved by ultrasonic oscillation, realizing the functional replacement of the protein separator, biological pool, ultraviolet lamp, and pure prototype in the existing circulating aquaculture system, simplifying the equipment structure of the circulating aquaculture system.

[0010] Preferably, the ultrasonic generating device comprises a plurality of ultrasonic vibrators arranged in a circular array with the straight circular tube as the center, and one end of the plurality of ultrasonic vibrators is respectively in contact with the tube wall of the straight circular tube.

[0011] By adopting this technical solution, the ultrasonic waves generated by the ultrasonic vibrator enter the straight circular tube from all directions and converge at the center of the straight circular tube, thereby improving the killing effect on parasite eggs and micro-parasites.

[0012] Preferably, the plurality of ultrasonic vibrators include at least a first ultrasonic vibrator for outputting 20 kHz ultrasonic waves and a second ultrasonic vibrator for outputting 220 kHz ultrasonic waves.

[0013] By adopting this technical solution: the output of multiple ultrasonic waves of different frequencies will produce harmonic superposition, amplifying the sound intensity and power, thus achieving the maximum killing effect on parasites and bacteria in the circulating water in a short time.

[0014] Preferably, it further comprises: an imbricate back pressure structure installed on the inner wall of the tube body of the straight round tube, the imbricate back pressure structure comprises a first hollow spherical crown body and a second hollow spherical crown body of the same shape; a first through hole is provided at the center of the top surface of the first hollow spherical crown body; a second through hole is provided at the center of the top surface of the second hollow spherical crown body; the bottom surface of the first hollow spherical crown body plate is fixedly connected to the bottom surface of the second hollow spherical crown body as a whole; and the bottom surface side edges of the first hollow spherical crown body and the bottom surface side edges of the second hollow spherical crown body are respectively connected to the inner wall of the tube body of the straight round tube. The cross-sectional radius of the bottom surface of the first hollow spherical crown body and the second hollow spherical crown body is consistent with the inner radius of the tube body of the straight round tube.

[0015] By adopting this technical solution: when the circulating water flows in the straight circular tube, based on the Venturi effect, it is in an accelerated state when it enters the small water tank composed of the first hollow spherical crown body and the second hollow spherical crown body from the first through hole, and is in a decelerated state when it flows out of the small water tank composed of the first hollow spherical crown body and the second hollow spherical crown body from the second through hole. Through the cooperation of multiple sequentially connected shingled back pressure structures, the flow rate of the circulating water entering the straight circular tube can be greatly reduced, so that the ultrasonic wave and ultraviolet light have sufficient time to act on the parasites, bacteria, viruses, etc. in the circulating water.

[0016] Preferably, the circulating water flow channel includes a plurality of straight circular tubes extending respectively along the horizontal x-axis direction, and the plurality of straight circular tubes are arranged in sequence from top to bottom along the vertical direction, and adjacent straight circular tubes are connected in sequence through arc-shaped bends.

[0017] By adopting this technical solution, the design length of a single-section straight round tube is reduced, thereby reducing the footprint of the equipment and achieving miniaturization of the equipment.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] Firstly, the present invention can improve the effective killing and removal rate of parasite eggs and micro-parasites in the circulating water of the circulating aquaculture system.

[0020] Secondly, the present invention can kill bacteria by means of ultrasonic vibration, and remove harmful substances such as nitrite and ammonia nitrogen under certain circumstances, thereby achieving functional replacement of protein separators, biological pools, ultraviolet lamps, and pure prototypes in existing systems.

[0021] Thirdly, the present invention greatly reduces the flow rate of the circulating water entering the straight circular tube by designing a shingled structure in the tube body, so that the ultrasound and ultraviolet light have sufficient time to act on the parasites, bacteria, viruses, etc. in the circulating water.

[0022] Fourthly, the present invention reduces the design length of a single-section straight circular tube, thereby reducing the floor space of the equipment and achieving miniaturization of the equipment.

[0023] Finally, the invention has a simple structure and is easy to prepare and use in large quantities. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1, please refer to Figure 1-4 :

[0032] A medium-pressure ultraviolet multi-frequency shingled ultrasonic circulating water treatment device comprises: a circulating water pipeline 100, an ultrasonic device 200, a medium-pressure ultraviolet lamp column 300, and a base 400.

[0033] The base 400 is configured to be fixedly installed on the ground.

[0034] The ultrasonic device 200 includes a mounting bracket 210 , and the bottom of the mounting bracket 210 is fixed on the base 400 .

[0035] The mounting bracket 210 is provided with three circular channels 220 extending along the horizontal x-axis direction respectively; the three circular channels 220 are arranged in sequence from top to bottom in the vertical direction.

[0036] One end of the circulating water pipeline 100 is provided with a water inlet, and the other end of the circulating water pipeline 100 is provided with a water outlet. The middle section of the circulating water pipeline 100 includes three straight round tubes 110 extending along the horizontal x-axis direction respectively; the three straight round tubes 110 are arranged in sequence from top to bottom in the vertical direction, and the adjacent straight round tubes 110 are connected in sequence through arc-shaped curved tubes 120. A plurality of medium-pressure ultraviolet lamp poles 300 are respectively inlaid and installed on the tube walls of the three straight round tubes 110, and the extension direction of the medium-pressure ultraviolet lamp poles 300 is consistent with the extension direction of the straight round tubes 110.

[0037] The three straight round tubes 110 pass through the mounting bracket 210 through the three circular channels 220, and the three straight round tubes 110 are arranged concentrically with the three circular channels 220 in a vertical section. Several ultrasonic generating devices are respectively installed on the inner walls of the three circular channels 220 and are arranged in sequence along the horizontal x-axis direction. Each of the ultrasonic generating devices includes a plurality of ultrasonic vibrators 230 arranged in a circular array with the straight round tube 110 as the center, and one end of the plurality of ultrasonic vibrators 230 is respectively abutted against the tube wall of the straight round tube 110. In practice, the plurality of ultrasonic vibrators 230 can be further configured to output a plurality of ultrasonic waves of different frequencies to the straight round tube 110, and the plurality of ultrasonic waves of different frequencies at least include 20khz ultrasonic waves and 220khz ultrasonic waves. That is, the plurality of ultrasonic vibrators 230 at least include a first ultrasonic vibrator 230 for outputting 20 kHz ultrasonic waves and a second ultrasonic vibrator 230 for outputting 220 kHz ultrasonic waves.

[0038] A plurality of shingled back-pressure structures 130 arranged in sequence along the horizontal x-axis direction are installed in the tube body of each straight round tube 110. The shingled back-pressure structure 130 is composed of a first hollow spherical crown body 131 and a second hollow spherical crown body 132 of the same shape. A first through hole 134 is provided at the center of the top surface of the first hollow spherical crown body 131; a second through hole 135 is provided at the center of the top surface of the second hollow spherical crown body 132; the bottom surface of the first hollow spherical crown body 131 and the bottom surface of the second hollow spherical crown body 132 are fixedly connected as a whole, and the first hollow spherical crown body 131 and the second hollow spherical crown body 132 together form a small water tank; the cross-sectional radius of the bottom surface of the first hollow spherical crown body 131 and the second hollow spherical crown body 132 are respectively consistent with the inner radius of the tube body of the straight round tube 110. The bottom side edges of the first hollow spherical crown 131 and the bottom side edges of the second hollow spherical crown 132 are respectively connected to the inner wall of the tube body of the straight circular tube 110. The bottom side edges of the first hollow spherical crown 131 and the bottom side edges of the second hollow spherical crown 132 are respectively provided with a plurality of lamp post inlay grooves 133 whose shapes match the medium-pressure ultraviolet lamp post 300. The plurality of shingled back-pressure structures 130 arranged in sequence along the horizontal x-axis direction are further configured as follows: when circulating water enters the straight circular tube 110, it can only flow from one side of the shingled back-pressure structure 130 to the other side of the shingled back-pressure structure 130 through the first through hole 134 and the second through hole 135 on the shingled back-pressure structure 130.

[0039] In practice, the working process is as follows:

[0040] The circulating water in the circulating aquaculture system is introduced into the circulating water pipeline 100 through the water inlet and finally flows out from the water outlet. In this process, when the circulating water flows along the circulating water pipeline 100 to the straight circular tube 110, the flow rate and water pressure of the circulating water are greatly reduced through the cooperation of multiple sequentially connected shingled back pressure structures 130 (after testing, the flow rate can be reduced to about 1 / 4 and the water pressure can be reduced to about 1 / 3 relative to the conventional circular tube of the same diameter). At this time, the ultrasonic generator distributed on the inner wall of the circular channel 220 outputs multi-frequency ultrasonic waves to the circulating water in the small water tanks formed by each shingled back pressure structure 130. Based on the harmonic superposition effect of the multi-frequency ultrasonic waves in the small water tanks, the sound intensity and power are amplified, causing maximum damage to microorganisms and eggs in a short time. The medium-pressure ultraviolet lamp column 300 uses an ultraviolet lamp filled with nitrogen that can withstand a pressure of 16kg. The ultraviolet light it outputs can effectively kill parasite eggs and micro-parasites that are severely damaged by ultrasonic waves. According to tests, the above structure has a parasite and worm egg removal rate of 98%, which can increase the parasite and worm egg killing rate by 3-4 times compared with the traditional circulating water system. At the same time, the ultrasonic vibration method can also synchronously kill bacteria and viruses, and remove harmful substances such as nitrite in the water body. According to tests, the above device can reduce the nitrite content in the circulating water output from the outlet by about 70%, and the ammonia nitrogen content by about 80%. In this way, the functional replacement of the protein separator, biological pool, ultraviolet lamp, and pure prototype in the existing circulating water aquaculture system is realized, and the equipment structure of the circulating water aquaculture system is simplified.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
