Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture equipment, and in particular relates to a water treatment and temperature control device for sea crab culture. Background Art

[0002] At present, the water treatment system for industrialized seawater aquaculture generally includes sedimentation tanks, mechanical filtration equipment (such as sand filtration, ceramic filtration, bag filtration, etc.), ozone sterilization equipment and air stone aeration equipment to clarify, filter, sterilize and oxygenate the original seawater to meet the requirements of industrial aquaculture water. However, the water produced by mechanical filtration is significantly affected by the source water, the water quality fluctuates greatly, and it is difficult to remove microorganisms such as bacteria and viruses, especially the control effect on Vibrio is poor: although ozone sterilization is widely used in seawater aquaculture production, once the content of natural organic matter in seawater is too high, the seawater disinfected by ozone will produce by-products such as trihalomethanes, causing poisoning of fish and shrimp, etc. Therefore, it is necessary to strictly control the amount of ozone, disinfection time and air head aperture, and at the same time ensure that the ozone in the seawater is completely degraded before flowing into the aquaculture pond. The ozone sterilization equipment has high process conditions: the air stone is used as the terminal to transport oxygen to the water body. Although the technology is simple, the oxygen utilization rate is low, and the oxygen distribution in the aquaculture water body is uneven, and it is difficult to achieve high dissolved oxygen in the aquaculture seawater. Summary of the invention

[0003] The invention provides a seawater crab breeding water treatment and temperature control device which can quickly process water debris, improve filtering efficiency, reduce crab stress response, circulate water and control water temperature.

[0004] In the present invention, a guiding assembly is provided on the inner wall of the breeding place, and a cutting device is provided on the bottom of the breeding place. Furthermore, the guide component is controlled by the cleaning system. The nozzle of the guide component faces downward and can discharge water with a faster flow rate, thereby promoting water circulation inside the breeding site. The water circulation can use the water flow to carry away fine pollutants from the breeding site for the next sewage treatment; secondly, it can use the circulating water to increase the oxygen content of the water. The flowing water enters the sewage treatment system under the action of the pump. In addition, the cleaning system can control the sewage treatment system, cutting device, etc.

[0005] In the present invention, the cutting device includes a bottom liquid storage bin, a fixing ring is provided inside the bottom liquid storage bin, the fixing ring is located at the center of the bottom liquid storage bin and is fixedly connected to the bottom liquid storage bin through a connecting rod, an outer shell is provided inside the fixing ring, and a wastewater conveying channel is provided at the right side of the bottom of the bottom liquid storage bin.

[0006] In the present invention, when it is necessary to deal with the pollutants in the storage room, the cleaning system controls the through hole located at the center of the bottom of the storage room to open, and the pollutants are placed in the narrow space between the cutting device and the shell, and the cutting device is started at the same time. Only a small redundancy is left between the cutting device and the shell, in order to fully squeeze the pollutants to achieve a better cutting effect. The cutting device will collide with the shell when working, and the filled pollutants can just avoid this. The pollutants covering the tool can protect the shell from being directly hit by the tool. The water that enters the cutting device together with the pollutants can also clean the pollutants covering the surface of the tool to a certain extent. At the same time, a fixing ring is provided on the shell to play a positioning and stabilizing effect. The pollutants that have been cut will be discharged into the bottom liquid storage bin along the water flow. A thick sponge pad is provided around the inner wall of the bottom liquid storage bin, which can reduce the noise generated by the cutting device when working to a considerable extent, and avoid the sea crabs from developing bad living habits due to the noise. When the water in the bottom liquid storage bin reaches a specified height, it will be discharged to the sewage treatment system along the wastewater conveying pipeline.

[0007] In the present invention, the cutting device includes a cutting component, a first blade body is evenly arranged above the cutting component, the first blade body is fixedly connected to the cutting component, a second blade body is surrounded below the cutting component, jet assemblies are evenly arranged at intervals in the vertical direction of the second blade body, the jet assemblies are evenly arranged in four positive directions of the cutting component and are fixedly connected to the cutting component, and in addition, the jet assembly is connected to a cylinder, and the cylinder is placed outside the breeding site.

[0008] In the present invention, the cutting device also includes a blade body part, which is mainly divided into an upper and lower part. The upper part is mainly a first blade body. The first blade body is evenly arranged around the cutting component in an arc shape. When the arc-shaped blade rotates, it can form a closed area, so that larger pollutants cannot pass through, while small pollutants successfully pass through the upper part. The lower part is provided with a second blade body and a jet assembly. The second blade body is designed as a multi-layer structure. The blade is provided with threads and surrounds the cutting component. The purpose is to further cut the pollutants so that the pollutants can be discharged into the sewage treatment system along the water flow. The jet assembly uses the jet head and air pump in the prior art. The jet assembly discharges a large amount of gas to make the small pollutants leave the cutting device from the lower pipe. In addition, the device has another technical effect that the guide component is connected to the outside with an air pump and the air pump is connected to the cutting component. When large particles need to be removed, by starting the air pump and when the water body circulates in the breeding box, the siphon effect formed by the jet of the bottom jet assembly is used to guide the particles inside the storage room downward, and the cutting device can be driven to rotate under the action of the water flow and the air flow, thereby destroying the rotation of the particles, and avoiding unnecessary additional energy consumption caused by the use of the motor.

[0009] In the present invention, the sewage treatment system includes an input pipe, which is welded to the top cover, a drum is provided under the top cover, a first bracket is vertically provided inside the drum, a filter screen is fixedly connected to the first bracket, a heating module is arranged around the inner wall of the drum, an output pipe is provided on one side of the lower end of the drum, a first cylinder is provided under the output pipe, and the first cylinder and the drum are located on the same axis and are rotatably connected.

[0010] In the present invention, the sewage treatment system is mainly used to clean up fine pollutants in the water transported from the breeding site. The drum arranged below the sewage treatment device can rotate independently of the first cylinder, and the first bracket connected to the drum rotates with the drum. Since a mesh body is fixedly connected to the first bracket, due to the easy adsorption of fine pollutants, the fine pollutants can be adsorbed on the mesh body when the mesh body rotates, thereby achieving the purpose of fully filtering the pollutants. Because centrifugal force is generated when the drum rotates, three bottom support cylinders arranged below the first cylinder are fixedly connected to three through holes located above the bottom support seat. In addition, a sponge pad is placed at the bottom of the through hole, which can greatly alleviate the wear caused by the rotation of the drum.

[0011] In the present invention, two ends of the first bracket are respectively provided with sliders, and the sliders are horizontally placed in the T-shaped grooves on the inner wall of the drum.

[0012] In the present invention, the size and thickness of the first bracket just fits the depth of the T-slot, so as to prevent the first bracket from being thrown out of the device when the drum is working. At the same time, the first bracket will be displaced along the y-axis direction of the T-slot due to the internal force of the flowing water body when working, so that the effective filtering area is increased, which is beneficial to remove impurities in the water body. At the same time, the first bracket and the mesh body on the upper part thereof that move up and down under the sliding action can contact the water body at the rotation center to a large extent, and the particles in the water are intercepted by contacting the mesh body. During the up and down displacement of the mesh body, the uniformity of distribution of the intercepted particles on the mesh body can be improved, avoiding the concentration of particles in a certain area on the mesh body, causing the filter interception effect of the area to decrease. At the same time, the particles that are not intercepted fall to the bottom due to the interception effect of the mesh body, and the water flow at the bottom mixes with the particles that are not intercepted again and drives the particles to move upward, promoting the particles to contact with the mesh body again, thereby improving the filtering effect.

[0013] Compared with the prior art, the present invention has significant technical progress as follows: a cutting device is provided, an air pump is connected to the outside of the guide component and the air pump is connected to the cutting component. When large particles need to be removed, the air pump is started and the water body circulates in the breeding box, and the siphon effect formed by the jet of the bottom jet component is utilized to guide the internal particles downward, and the cutting device can be driven to rotate under the action of the water flow and the air flow, thereby destroying the rotation of the particles, and avoiding unnecessary additional energy consumption caused by the use of the motor; a sewage treatment system is provided, and the sewage treatment system includes a first bracket. When the support bracket is working, it will be displaced along the y-axis direction of the T-slot due to the internal force of the flowing water body, so that the effective filtering area is increased, which is conducive to removing impurities in the water body. At the same time, the first bracket and the upper mesh body thereof that move up and down under the sliding action can contact the water body at the rotation center to a greater extent, and the particles in the water are trapped by contacting the mesh body. During the up and down displacement of the mesh body, the uniformity of the distribution of the trapped particles on the mesh body can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Embodiment 1: Reference Figure 1 , Figure 2 , Figure 3 As shown, In the present invention, a guide assembly 3 is provided on the inner wall of the breeding place 1, and a cutting device 105 is provided on the bottom of the breeding place 1. Furthermore, the guide component 3 is controlled by the cleaning system 2. The nozzle of the guide component 3 faces downward and can discharge a water flow with a faster flow rate, thereby promoting water circulation inside the breeding site 1. The water circulation can use the water flow to carry away fine pollutants from the breeding site 1 for the next sewage treatment; secondly, it can use the circulating water to increase the oxygen content of the water. The flowing water enters the sewage treatment system 5 under the action of the pump. In addition, the cleaning system 2 can control the sewage treatment system 5, the cutting device 105, etc.

[0019] When it is necessary to deal with the pollutants in the storage room 104, the cleaning system 7 controls the through hole located at the center below the storage room 104 to open, and puts the pollutants into the narrow space between the cutting device 105 and the shell 106, and starts the cutting device 105 at the same time. Only a small redundancy is left between the cutting device 105 and the shell 106, in order to fully squeeze the pollutants to achieve a better cutting effect. The cutting device 105 will collide with the shell 106 when working, and the filled pollutants can just avoid this. The pollutants covering the tool can protect the shell 106 from being directly hit by the tool, and the pollutants The water that enters the cutting device 105 together can also clean the pollutants covering the surface of the tool to a certain extent. At the same time, the fixing ring 105 is mounted on the outer shell 106 to play a positioning and stabilizing role. The pollutants after cutting will be discharged into the bottom liquid storage tank 108 along the water flow. The inner wall of the bottom liquid storage tank 108 is surrounded by a thick sponge pad, which can reduce the noise generated by the cutting device 105 when it is working to a considerable extent, and prevent sea crabs from developing bad living habits due to the noise. When the water in the bottom liquid storage tank 108 reaches the specified height, it will be discharged to the sewage treatment system 5 along the wastewater conveying pipe 109.

[0020] In the present invention, the cutting device 105 includes a cutting component 401, a first blade body 402 is evenly distributed above the cutting component 401, the first blade body 402 is fixedly connected to the cutting component 401, a second blade body 403 is surrounded below the cutting component 401, and jet components 404 are evenly distributed at intervals in the vertical direction of the second blade body 403. The jet components 404 are evenly distributed in four positive directions of the cutting component 401 and are fixedly connected to the cutting component 401. In addition, the jet component 404 is connected to a cylinder, and the cylinder is placed outside the breeding place 6.

[0021] The cutting device 105 also includes a blade part, which is mainly divided into two parts, the upper part is mainly a first blade 402, the first blade 402 is evenly arranged around the cutting component 401 in an arc shape, and the arc-shaped blade can form a closed area when rotating, so that larger pollutants cannot pass through, while small pollutants successfully pass through the upper part, and the lower part is provided with a second blade 403 and an injection component 404. The second blade 403 is designed as a multi-layer structure, and the blade is provided with a thread and surrounds the cutting component 401, the purpose is to further cut the pollutants so that the pollutants can be discharged into the sewage treatment system 5 along the water flow, and the injection component 404 is operated. Using the jet head and air pump in the prior art, the jet component 404 discharges a large amount of gas to make fine pollutants leave the cutting device 105 from the lower pipe. In addition, the device has another technical effect, that is, the guide component 8 is externally connected to the air pump and the air pump is connected to the cutting component 401. When large particles need to be removed, by starting the air pump and circulating the water in the breeding box, the siphon effect formed by the jet of the bottom jet component 404 is utilized to guide the particles inside the storage room 104 downward, and the cutting device 105 can be caused to rotate under the action of the water flow and air flow, thereby destroying the rotation of the particles, and avoiding unnecessary additional energy consumption caused by the use of motors.

[0022] Embodiment 3: Reference Figure 1 , Figure 4 As shown, the sewage treatment system 5 includes an input pipe 501, which is welded to a top cover 502. A drum 503 is provided below the top cover 502. A first bracket 504 is vertically provided inside the drum 503. A filter screen is fixedly connected to the first bracket 504. A heating module 505 is arranged around the inner wall of the drum 503. An output pipe 516 is provided on one side of the lower end of the drum 503. A first cylinder 511 is provided below the output pipe 516. The first cylinder 511 and the drum 503 are located on the same axis and are rotatably connected.

[0023] The sewage treatment system 5 is mainly used to clean up the fine pollutants in the water transported from the breeding site 6. The drum 503 arranged below the sewage treatment device can rotate independently of the first cylinder 511, and the first bracket 504 connected to the drum 503 rotates with the drum. Since a mesh is fixedly connected to the first bracket 504, and the fine pollutants are easily adsorbed, the fine pollutants can be adsorbed on the mesh when the mesh rotates, thereby achieving the purpose of fully filtering the pollutants. Because centrifugal force is generated when the drum 503 rotates, the three bottom support cylinders 506 arranged below the first cylinder 511 are fixedly connected to the three through holes 507 located above the bottom support seat 508. In addition, a sponge pad is placed at the bottom of the through hole 507, which can greatly alleviate the wear caused by the rotation of the drum 503.

[0024] In the present invention, two ends of the first bracket 504 are respectively provided with sliders, and the sliders are horizontally placed in the T-shaped grooves on the inner wall of the drum.

[0025] The size and thickness of the first bracket 504 just fits the depth of the T-slot, so as to prevent the first bracket 504 from being thrown out of the device when the drum 503 is working. At the same time, the first bracket 504 will be displaced along the y-axis direction of the T-slot due to the internal force of the flowing water body when working, so that the effective filtering area is increased, which is beneficial to remove impurities in the water body. At the same time, the first bracket 504 and the mesh body on its upper part that move up and down under the sliding action can contact the water body at the rotation center to a large extent, and the particles in the water are intercepted by the contact with the mesh body. In the process of the up and down displacement of the mesh body, the uniformity of the distribution of the intercepted particles on the mesh body can be improved, so as to avoid the particles being concentrated in a certain area on the mesh body, causing the filter interception effect of the area to decrease. At the same time, the particles that are not intercepted fall to the bottom due to the interception effect of the mesh body, and the water flow at the bottom mixes with the particles that are not intercepted again and drives the particles to move upward, promoting the particles to contact with the mesh body again, thereby improving the filtering effect.

[0026] In addition, since the heating module 505 is also working synchronously while the first bracket 504 drives the mesh to rotate, the driven water flow can be heated up to a suitable temperature by the heating module 505 again, and then flow back to the cleaning system 2 through the output pipe 516 and then distributed to each breeding site 1, so as to avoid the temperature of the water being too low, which makes the sea crab unable to adapt to the temperature of the current living environment and causes illness or death.

[0027] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
