Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a centralized aquaculture wastewater treatment device. Background Art

[0002] Aquaculture wastewater refers to wastewater generated in the production process of aquaculture, which contains a large amount of nutrients, organic matter and microorganisms. The centralized aquaculture wastewater treatment device is an equipment system used to treat wastewater generated in the production of aquaculture. Through pretreatment and other processes, the organic matter, microorganisms and pollutants in the wastewater are removed or degraded to achieve the purpose of purifying water quality and protecting the environment.

[0003] Some existing treatment devices usually need to screen out the dirt in the wastewater when pre-treating aquaculture wastewater. After screening, the water in the dirt usually flows naturally into the water storage box, and the working efficiency is relatively low. After such treatment devices have been used for a period of time, they need to be stopped first, and then the dirt in the collection box needs to be manually taken out, which is troublesome.

[0004] Therefore, those skilled in the art have provided a centralized aquaculture wastewater treatment device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and the proposed centralized aquaculture wastewater treatment device can squeeze the dirt in the fixed block by arranging a squeezing mechanism, accelerate the flow of water in the dirt to the water storage box, and improve the working efficiency. Through the lifting mechanism, when the dirt in the fixed block reaches a certain amount, it automatically slides out from the slope of the fixed block, which is more convenient.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a centralized aquaculture wastewater treatment device, comprising a filtering mechanism, an extruding mechanism and two lifting mechanisms, the filtering mechanism comprising a box, a filtering tank, two discharge ports and a water pump, first filter screens are fixedly arranged on both sides between the front and rear inner walls of the filtering tank, a plurality of second filter screens are fixedly arranged on the lower side between the front and rear inner walls of the filtering tank, a water storage box is fixedly arranged on the lower side of the front and rear end surfaces of the box, and a water pipe is fixedly arranged on the water outlet of the water pump;

[0007] The extrusion mechanism includes two fixed blocks, a motor and two bidirectional screw rods, a belt is arranged between one side of the outer end surfaces of the two bidirectional screw rods, and extrusion plates are threadedly sleeved on both sides of the outer end surfaces of the two bidirectional screw rods. The two lifting mechanisms include two electric telescopic rods, two first baffles, two second baffles and two connecting plates. The output ends of the two electric telescopic rods are fixedly provided with folding plates, and ultrasonic sensors are embedded on the opposite sides of the inner top surfaces of the two folding plates.

[0008] Through the above technical scheme, aquaculture wastewater is introduced into the upper end of the box body. At this time, the dirt in the wastewater is blocked by the first filter screen and slides into the interior of the fixed block along the slope. At this time, the motor drives the four extrusion plates to move closer to the middle in pairs through the bidirectional screw. In the process of moving closer, the dirt in the fixed block is squeezed, so that the water in the dirt is squeezed out and flows into the water storage box along the hole opened at the bottom of the fixed block. At this time, the water pump sucks out the sewage in the water storage box, and then passes it into the upper end of the box body through the water pipe. When the ultrasonic sensor detects that the dirt in the fixed block reaches a certain height, the electric telescopic rod is controlled to drive the folding plate to move upward. During the movement of the folding plate, the first baffle and the second baffle move upward together. The first baffle does not block the slope direction of the fixed block, and the second baffle blocks the discharge port. At this time, the dirt in the fixed block can slide out of the interior of the fixed block along the slope.

[0009] Furthermore, the filter tank is provided on the upper end surface of the box body, the two discharge ports are respectively provided on the upper sides of the front and rear end surfaces of the box body, and the two second baffles are respectively penetrated and slidably provided on the inner bottom surfaces of the two discharge ports;

[0010] Through the above technical solution, when the second baffle moves upward, the discharge port is blocked to prevent the discharge port from continuing to slide dirt into the interior of the fixed block.

[0011] Furthermore, the water pump is fixedly connected to the box body, and the two water storage boxes are connected to the water inlet of the water pump through pipes;

[0012] Through the above technical solution, the sewage in the water storage box can be led to the upper end of the box body by providing power through the water pump, so that the sewage can be filtered.

[0013] Furthermore, the two fixing blocks are fixedly arranged on the lower sides of the front and rear end surfaces of the box body, and the lower end surfaces of the four extrusion plates are slidably arranged on both sides of the inner bottom surfaces of the two fixing blocks;

[0014] Through the above technical solution, the bidirectional screw drives the four extrusion plates to move closer to the middle in pairs during the rotation process, and in the process of moving closer, the protrusions of the extrusion plates will block the discharge port to prevent dirt from sliding into the original position of the extrusion plates.

[0015] Furthermore, the motor is fixedly connected to one of the front sides of the two fixed blocks, the two bidirectional screw rods are rotatably arranged on the upper sides between the inner walls of the two sides of the two fixed blocks, and the output end of the motor is fixedly connected to one of the front sides of the two bidirectional screw rods;

[0016] Through the above technical solution, the bidirectional screw rod on the front side is driven to rotate by the motor, and during the rotation process, the bidirectional screw rod on the rear side can be driven to rotate together through the belt.

[0017] Furthermore, the two electric telescopic rods are fixedly connected to the box body, and the two second baffles are fixedly connected to the two folding plates through connecting plates respectively;

[0018] Through the above technical solution, the operation of the electric telescopic rod is controlled by an ultrasonic sensor, making it more intelligent.

[0019] Furthermore, the two first baffles are respectively slidably arranged on opposite sides between the inner walls of the two fixing blocks, and the two first baffles are respectively fixedly connected to the two folding plates;

[0020] Through the above technical solution, the folding plate is driven to move upwards by the electric telescopic rod, and during the movement, the first baffle is driven to move upwards as well, thereby removing the shielding of dirt.

[0021] The utility model has the following beneficial effects:

[0022] 1. The centralized aquaculture wastewater treatment device proposed by the utility model is to pass aquaculture sewage into the upper end of the box body. During the passing process, the wastewater is blocked by the first filter screen and slides into the interior of the fixed block along the slope. The sewage passes through the first filter screen and enters the lower end of the filter tank. At this time, the sewage is filtered multiple times by the multi-layer second filter screens, and the wastewater that slides into the interior of the fixed block, under the action of the squeezing plate, the water inside the wastewater is passed into the water storage box, and finally the sewage is passed to the upper end of the box body through a water pump for re-filtration. By setting the squeezing mechanism, it can squeeze the waste in the fixed block, speed up the flow of water in the waste to the water storage box, and improve the work efficiency.

[0023] 2. The centralized aquaculture wastewater treatment device proposed by the utility model, when the ultrasonic sensor detects that the dirt on the fixed block reaches a certain height, controls the electric telescopic rod to start running, and the electric telescopic rod drives the folding plate to move upward. During the movement of the folding plate, the first baffle plate and the second baffle plate move upward together, so that the first baffle plate does not block the sloped sliding end of the fixed block, and in the process of dirt sliding out, the discharge port is blocked by the second baffle plate to prevent new dirt from entering the interior of the fixed block. Through the lifting mechanism, when the dirt in the fixed block reaches a certain amount, it automatically slides out from the slope of the fixed block, which is more convenient.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-6 The utility model provides an embodiment: a centralized aquaculture wastewater treatment device, including a filtering mechanism 1, an extruding mechanism 2 and two lifting mechanisms 3. The filtering mechanism 1 includes a box 101, a filter tank 102, two discharge ports 105 and a water pump 107. A first filter screen 103 is fixedly arranged on both sides between the front and rear inner walls of the filter tank 102. A plurality of second filter screens 104 are fixedly arranged on the lower side between the front and rear inner walls of the filter tank 102. Aquaculture wastewater is introduced into the upper end of the box 101. During the introduction process, the dirt is blocked by the first filter screen 103. The wastewater passes through the first filter screen 103 and enters the lower end of the filter tank 102. At this time, the wastewater is filtered multiple times by the multi-layer second filter screens 104. Finally, the filtered wastewater flows out from the through hole opened on one side of the box 101.

[0034] The front and rear ends of the box body 101 are fixedly provided with a water storage box 106, and the water outlet of the water pump 107 is fixedly provided with a water pipe 108. The extrusion mechanism 2 includes two fixed blocks 201, a motor 202 and two bidirectional screw rods 203. A belt 204 is provided between one side of the outer end faces of the two bidirectional screw rods 203. Both sides of the outer end faces of the two bidirectional screw rods 203 are threadedly sleeved with an extrusion plate 205. The water pump 107 is fixedly connected to the box body 101. The two water storage boxes 106 are connected to the water pump 107 through a pipe. The water inlet of the pump 107 is connected, the two fixed blocks 201 are fixedly arranged on the lower sides of the front and rear end surfaces of the box body 101 respectively, the lower end surfaces of the four extrusion plates 205 are slidably arranged on both sides of the inner bottom surfaces of the two fixed blocks 201, the motor 202 is fixedly connected to one of the front sides of the two fixed blocks 201, the two bidirectional screw rods 203 are rotatably arranged on the upper side between the inner walls on both sides of the two fixed blocks 201, and the output end of the motor 202 is fixedly connected to one of the front sides of the two bidirectional screw rods 203.

[0035] When the dirt in the wastewater is blocked by the first filter screen 103, it will slide into the interior of the fixed block 201 along the slope of the first filter screen 103. At this time, the motor 202 drives the four squeezing plates 205 to move closer to the middle in pairs through the bidirectional screw rod 203. During the moving closer process, the dirt in the fixed block 201 is squeezed, so that the water in the dirt is squeezed out and flows into the water storage box 106 along the holes opened at the bottom of the fixed block 201. At this time, the water pump 107 sucks out the sewage in the water storage box 106, and then passes it into the upper end of the box body 101 through the water pipe 108. In the moving closer process, the protrusion of the squeezing plate 205 will block the discharge port 105 to prevent the dirt from sliding into the original position of the squeezing plate 205. The dirt that slides out of the discharge port 105 will only fall to the middle position of the fixed block 201, that is, the position between the four squeezing plates 205 in pairs.

[0036] The two lifting mechanisms 3 include two electric telescopic rods 301, two first baffles 303, two second baffles 305 and two connecting plates 306. The output ends of the two electric telescopic rods 301 are fixedly provided with folding plates 302. The two folding plates 302 are embedded with ultrasonic sensors 304 on the opposite sides of the top surfaces. The filter tank 102 is opened on the upper end surface of the box body 101. The two discharge ports 105 are respectively opened on the upper sides of the front and rear end surfaces of the box body 101. The two second baffles 305 are respectively slidably arranged on the inner bottom surfaces of the two discharge ports 105. The two electric telescopic rods 301 are fixedly connected to the box body 101. The two second baffles 305 are respectively fixedly connected to the two folding plates 302 through the connecting plates 306. The two first baffles 303 are respectively slidably arranged on the opposite sides between the inner walls of the two fixed blocks 201. The two first baffles 303 are respectively fixedly connected to the two folding plates 302.

[0037] When the ultrasonic sensor 304 detects that the dirt on the fixed block 201 reaches a certain height, the electric telescopic rod 301 is controlled to drive the folding plate 302 to move upward. During the movement, the folding plate 302 drives the first baffle 303 and the second baffle 305 to move upward together. The first baffle 303 does not block the slope direction of the fixed block 201. Under the action of the connecting plate 306, the second baffle 305 passes through the discharge port 105 and moves upward, thereby blocking the discharge port 105. At this time, the dirt in the fixed block 201 can slide out of the fixed block 201 along the slope, and no new dirt will slide into the fixed block 201 along the discharge port 105. When the electric telescopic rod 301 is running, the motor 202 is still in working condition, that is, when the dirt inside one fixed block 201 is removed, the other fixed block 201 is still storing dirt.

[0038] Working principle: Aquaculture sewage is introduced into the upper end of the box 101. During the introduction process, the sewage passes through the first filter screen 103, and the dirt is blocked by the first filter screen 103 and slides into the interior of the fixed block 201 along the slope of the first filter screen 103. At this time, the sewage passes through the second filter screen 104 and finally flows out from the through hole of the box 101. During the introduction process, the motor 202 is in operation, so that the two squeezing plates 205 in the fixed block 201 move closer to the middle to squeeze the dirt in the fixed block 201. At this time, the water produced after squeezing is passed to the upper end of the box 101 through the water pump 107 for re-filtration. When the ultrasonic sensor 304 detects that the dirt in the fixed block 201 reaches a certain height, the electric telescopic rod 301 is controlled to drive the folding plate 302 to move upward, so that the dirt inside the fixed block 201 slides out of the fixed block 201 along the slope.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
