Description

Technical Field

[0001] The invention belongs to the field of sewage treatment, and specifically discloses a sewage treatment device for fish farming. Background Art

[0002] The treatment of fish pond sewage can effectively reduce harmful substances in the water, improve water quality, provide a better living environment for fish, and thus improve aquaculture benefits. Through biological treatment technology, harmful substances such as organic matter and ammonia nitrogen in sewage can be further decomposed and transformed to generate harmless substances such as carbon dioxide and water, thereby improving water quality, reducing the occurrence of fish diseases, and improving aquaculture benefits.

[0003] Among the existing treatment methods, most of them are to continuously filter the fish pond water through a drum-type microfilter. The microfilter filtering method is to pump water, filter it, and then discharge it back into the fish pond. The microfilter needs to be installed on the ground, so the positions of water extraction and discharge are relatively fixed. It can only effectively circulate and filter nearby water bodies, and the filtering effect on water bodies far away from the microfilter is extremely limited. If the water body is less turbulent and has poor fluidity, the filtering effect of the water body far away from the microfilter will be further reduced. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figure 1-Figure 8A sewage treatment device for fish farming shown in the figure includes a filtering mechanism 1 and four adjusting mechanisms 2, and the four adjusting mechanisms 2 are connected to the filtering mechanism 1 by a pull rope. The filtering mechanism 1 is used to filter harmful substances in the water. The filtering mechanism 1 includes a connecting frame 3, the outer wall of the connecting frame 3 is fixedly connected with uniformly distributed first buoys 4, the bottom of the connecting frame 3 is fixedly connected with uniformly distributed second buoys 10, the top of the outer wall of the connecting frame 3 is fixedly connected with uniformly distributed connecting ears 5, the bottom of the connecting frame 3 is provided with a first filtering component 11, and the interior of the first filtering component 11 is provided with a second filtering component 12. The adjusting mechanism 2 is used to adjust the position of the filtering mechanism 1 in the water. The adjusting mechanism 2 includes a shell 30, the bottom four corners of the shell 30 are fixedly connected with universal wheels 31, and one side of the shell 30 is provided with a pull rod. 32. A second pay-off assembly 37 is provided inside the shell 30, and a pull rope is wound inside the second pay-off assembly 37. The bottom of the inner wall of the second pay-off assembly 37 is fixedly connected with a first transmission wheel 39 and a second transmission wheel 40 which are staggered, and the pull rope passes through the first transmission wheel 39 and the second transmission wheel 40 in sequence and extends out of the shell 30. The pull rope is limited multiple times by setting the second transmission wheel 40 and the first transmission wheel 39 to keep it in a taut state. The four adjustment mechanisms 2 are started according to a predetermined program to jointly pull the filter mechanism 1 to float on the water surface, so that the filter mechanism 1 can move on the water surface according to a specified trajectory, and at the same time, the water on the trajectory is filtered and adsorbed to adsorb harmful substances to improve water quality, thereby solving the problem that the filtering device in the prior art has poor filtering effect and is greatly affected by the fluidity of the water body.

[0032] The central axis of the second pay-off assembly 37 is provided with a rotating sleeve 38, and an electric push rod 33 is fixedly installed on the top of the inner wall of the shell 30, and the output end of the electric push rod 33 is fixedly connected to the mounting plate 34, and the bottom of the mounting plate 34 is fixedly installed with a second motor 35, and the output end of the second motor 35 is fixedly connected to the plug post 36, and the plug post 36 is adapted to the rotating sleeve 38. After the plug post 36 is inserted into the interior of the rotating sleeve 38, the plug post 36 can drive the second pay-off assembly 37 to rotate, thereby forming a strong pulling force to pull the pull rope so that the filtering mechanism 1 floats on the water surface. When one of the adjustment mechanisms 2 reels the pull rope, the electric push rod 33 inside the other adjustment mechanism 2 drives the second motor 35 to rise and then pulls the plug post 36 out of the interior of the rotating sleeve 38. This design ensures that when the pull rope inside the second pay-off assembly 37 is pulled out, it no longer drives the motor shaft of the second motor 35 to rotate in the opposite direction, so that the pull rope can slide out more smoothly.

[0033] The first filter assembly 11 includes a first protective cylinder 15 fixedly connected to the bottom of the outer wall of the connecting frame 3, the inner wall of the first protective cylinder 15 is fixedly connected with a first adsorption member 16, a first linkage groove 17 is arranged between the first protective cylinder 15 and the first adsorption member 16, the second filter assembly 12 includes a second protective cylinder 19 inserted and slidably connected to the inside of the first linkage groove 17, the inside of the second protective cylinder 19 is fixedly connected with a second adsorption member 20, a second linkage groove 21 is arranged between the second adsorption member 20 and the second protective cylinder 19, and the first adsorption member 16 is inserted and slidably connected to the inside of the second linkage groove 21, the outer walls of the second protective cylinder 19 and the first protective cylinder 15 are provided with uniformly distributed flow holes 18, the bottom of the second filter assembly 12 is fixedly connected with a first filter plate 13, the outer wall of the first filter plate 13 is fixedly connected with a counterweight block 14, the top of the connecting frame 3 is fixedly connected with a support plate 6, the top central axis of the support plate 6 is fixedly installed with a first pay-off assembly 8, the top of the support plate 6 is fixedly installed with a first motor 7, and the first filter assembly 12 is fixedly installed with a first motor 7. The output end of a motor 7 is connected to the first pay-off assembly 8, and the first pay-off assembly 8 is connected to the top of the baffle 26 through a traction rope. The flow holes 18 on the outer wall of the first protective tube 15 and the flow holes 18 on the outer wall of the second protective tube 19 are staggered. After the first motor 7 is started, the second filter assembly 12 can be pulled upward to allow the second protective tube 19 to be retracted into the first linkage groove 17. When the second protective tube 19 is retracted into the first linkage groove 17, the flow holes 18 of the second protective tube 19 and the first protective tube 15 are blocked by each other, so that both are in a closed state. When feeding feed into the fish pond, it can ensure that the filter mechanism 1 will not suck the feed into the interior. When the second filter assembly 12 is pulled out of the first filter assembly 11 by the counterweight 14, the water enters the first filter assembly 11 and the second filter assembly 12 through the flow holes 18, wherein harmful substances are respectively absorbed by the first adsorbent 16 and the second adsorbent 20 to ensure the safety of water quality.

[0034] A waterproof motor 22 is fixedly installed inside the second adsorption component 20, and a rotating shaft 24 is fixedly connected to the output end of the waterproof motor 22, and the bottom of the rotating shaft 24 is inserted and rotatably connected to the top of the first filter plate 13, and a spiral blade 23 is fixedly connected to the outer wall of the rotating shaft 24. A diffusion cylinder 25 is fixedly connected to the inside of the second protective cylinder 19, and a second filter plate 29 is fixedly connected to the bottom of the diffusion cylinder 25. The inner wall of the diffusion cylinder 25 is fixedly connected to a uniformly distributed and integrally arranged guide plate 28, and a baffle 26 is fixedly connected to the top of the diffusion cylinder 25. The outer wall of the baffle 26 is provided with uniformly distributed and integrally vortex-shaped arc holes 27. After the second filter component 12 is immersed in water, the waterproof motor 22 is started to drive the spiral blade 23 to rotate, which can form a vortex to make the surrounding water flow rapidly. When the vortex enters the interior of the diffusion cylinder 25, it is guided by the guide plate 28 and the arc hole 27, and quickly diffuses to the outside from the interior of the first filter component 11. This design accelerates the water circulation effect and improves the adsorption efficiency of the adsorption component.

[0035] A balancing block 9 is fixedly connected to the top of the support plate 6. The balancing block 9 and the first motor 7 are each located on one side of the first line-releasing assembly 8, so that both sides of the top of the support plate 6 are in a uniformly weighted state, which is more conducive to the device floating stably on the water.

[0036] Working principle:

[0037] By setting the second transmission wheel 40 and the first transmission wheel 39 to limit the pull rope multiple times, so that it is in a tight state, the four adjustment mechanisms 2 are respectively started according to a predetermined program to jointly pull the filter mechanism 1 to float on the water surface, so that the filter mechanism 1 can move on the water surface along a specified track, and at the same time filter and adsorb the water on the track to adsorb harmful substances to improve water quality, thereby solving the problem that the filtering device in the prior art has poor filtering effect and is greatly affected by the fluidity of the water body;

[0038] After the plug 36 is inserted into the rotating sleeve 38, the plug 36 can drive the second pay-off assembly 37 to rotate, thereby generating a strong pulling force to pull the drawstring so that the filter mechanism 1 floats on the water surface. When one of the adjustment mechanisms 2 reels the drawstring, the electric push rod 33 inside the other adjustment mechanism 2 drives the second motor 35 to rise, thereby pulling the plug 36 out of the rotating sleeve 38. This design ensures that when the drawstring inside the second pay-off assembly 37 is pulled out, it no longer drives the motor shaft of the second motor 35 to rotate in the opposite direction, thereby enabling the drawstring to slide out more smoothly.

[0039] After the first motor 7 is started, the second filter assembly 12 can be pulled to move upward, so that the second protective cylinder 19 is stored in the first linkage groove 17. When the second protective cylinder 19 is stored in the first linkage groove 17, the flow holes 18 of the second protective cylinder 19 and the first protective cylinder 15 are blocked by each other, so that both are in a closed state. When feeding feed into the fish pond, it can be ensured that the filter mechanism 1 will not suck the feed into the inside. When the second filter assembly 12 is pulled out of the first filter assembly 11 by the counterweight 14, the water enters the first filter assembly 11 and the second filter assembly 12 through the flow hole 18, and the harmful substances are absorbed by the first adsorption member 16 and the second adsorption member 20 respectively, so as to ensure the safety of water quality.

[0040] After the second filter component 12 is immersed in water, the waterproof motor 22 is started to drive the spiral blade 23 to rotate, which can form a vortex to make the surrounding water flow rapidly. When the vortex enters the interior of the diffusion tube 25, it is guided by the guide plate 28 and the arc hole 27, and quickly diffuses to the outside from the interior of the first filter component 11. This design accelerates the water circulation effect and improves the adsorption efficiency of the adsorbent.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
