Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to an environmentally friendly aquaculture transfer trailer and a use method thereof. Background Art

[0002] Herders frequently migrate, sometimes for short distances, from their homes to grazing areas, and sometimes for longer, seasonal migrations. During these long-distance migrations, herders carry their tents and daily necessities along well-trodden paths, herding their livestock to pastures at varying altitudes, seeking access to water and grass. Traditionally, herders have driven their livestock on foot, a time-consuming and laborious process, often exposing them to attacks by wild animals and resulting in losses. Therefore, a transportation method for these migrations is urgently needed.

[0003] The invention patent with publication number CN109353264A proposes a mobile livestock breeding vehicle that can automatically breed and clean livestock. The vehicle has a complex structure, is difficult to manufacture, has high costs, and is inconvenient to operate and manage. Summary of the Invention

[0007] The trailer body adopts a rectangular structure. Depending on the height of the livestock, the interior of the rectangular body is set up as two or three layers. The bottom plate of each layer is provided with several grooves running longitudinally from the front to the rear of the vehicle, and the grooves are provided with holes. A collection pipe is provided at the lower part of the groove. The collection pipe is provided with a slope, with the rear of the vehicle higher and the front lower. Flushing water containing feces and urine flows from the groove into the collection pipe and then collects into the excrement treatment system.

[0008] Furthermore, a water trough is provided on the inner wall of the carriage of the trailer body, and the water trough is connected to a water pipe provided on the carriage wall.

[0009] Furthermore, an anti-skid plate is provided on the upper surface of the rear door, and foldable baffles are hinged on both sides of the rear door to prevent slipping and falling when the rear door is unfolded to form a passage and livestock get on and off the vehicle.

[0010] Furthermore, the clean water tank is arranged on the upper part of the trailer body in the direction of the front of the vehicle, and the clean water tank provides clean drinking water and cleaning water. The clean water tank is connected to the drinking trough through a water pipe.

[0011] Furthermore, the above-mentioned excrement treatment system is arranged at the front direction of the trailer body and the lower part of the clean water tank. The excrement treatment system includes a sedimentation separation box, an anaerobic box, a biochemical filter box and a disinfection water tank; the sedimentation separation box, the anaerobic box, the biochemical filter box and the disinfection water tank are connected in sequence.

[0012] Furthermore, the above-mentioned sedimentation separation tank is equipped with a sedimentation separation tank inlet pipe. A baffle is installed within the sedimentation separation tank, which forms a wastewater flow channel with the tank wall. The sedimentation separation tank inlet pipe is connected to the wastewater flow channel. An exhaust hole is provided at the top of the sedimentation separation tank, through which exhaust gases generated by the anaerobic reaction in the sedimentation separation tank are discharged. A self-floating decanter is installed above the water surface of the sedimentation separation tank. This decanter can decant clarified water from the still water surface without disturbing the sediment, thereby ensuring the quality of the effluent. The bottom of the sedimentation separation tank is designed with a conical structure, and a sediment discharge valve is installed at the bottom of the cone. The sedimentation separation tank operates intermittently. Flushing water generated by the transfer trailer enters the sedimentation separation tank through a pipe and the sedimentation separation tank inlet pipe. Flushing water containing feces and urine is precipitated in the sedimentation separation tank, and solids are separated from water. The solids are then discharged through the sediment discharge valve to the composting site for treatment. The separated water passes through the decanter and enters the anaerobic tank. The sedimentation separation time of the sedimentation separation box is 1.5 to 2 hours. If the sedimentation time is prolonged, anaerobic reaction will occur in the wastewater.

[0013] Furthermore, the anaerobic box includes an anaerobic section, an anoxic section and an anaerobic section separated by a baffle. The head end of the anaerobic section is provided with an anaerobic box water inlet pipe for supplying wastewater, and the anaerobic box water inlet pipe is connected to the decanter of the sedimentation separation box. The end of the facultative oxic section is connected to the head end of the anoxic section, and the end of the anoxic section is connected to the head end of the anaerobic section. The lower part of the baffle on the water inlet side of the anoxic section and the anaerobic section is provided with a 45-degree angle to avoid the impact caused by the entry of water, thereby playing a role in buffering the water flow and evenly distributing water; an anaerobic box three-phase separator and an anaerobic box overflow weir are provided at the end of the anaerobic section, and the anaerobic box overflow weir is connected to the anaerobic box outlet pipe; the bottom of the facultative oxic section, anoxic section and anaerobic section is designed to be a conical structure, and the conical structure is connected to the sludge discharge valve; the upper cover of the facultative oxic section, anoxic section and anaerobic section of the anaerobic box is designed to be a conical structure, and the top of the conical structure is provided with an independent methane waste gas collecting pipe; anaerobic box fillers are provided in the facultative oxic section, anoxic section and anaerobic section.

[0014] Furthermore, the biochemical filter box has a cylindrical upper portion and a conical lower portion, comprising a downflow zone, an upflow zone, and a sludge zone. The downflow zone is located in the middle of the biochemical filter box's cylindrical structure and is a cylindrical structure. The upper portion of the downflow zone is equipped with a biochemical filter inlet pipe and a water distribution pipe, which connects to the anaerobic chamber outlet pipe. A biochemical filler is located in the middle of the downflow zone, and an aeration pipe is located in the lower portion of the downflow zone. The aeration pipe is connected to an aerator mounted on the outer wall of the biochemical filter box. A guide plate with a trumpet-shaped longitudinal cross-section is located at the bottom of the downflow zone. The upflow zone is located around the downflow zone and above the guide plate. Filter material is provided in the upflow zone, and a biochemical filter overflow weir is located at the upper outlet of the upflow zone. The sludge zone is located at the bottom of the biochemical filter box and below the downflow and upflow zones. A sludge discharge valve is located at the bottom of the sludge zone.

[0015] Furthermore, a feed trough is provided on the inner wall of the trailer body, connected to a feed inlet provided on the wall. Water from the biochemical filter enters a disinfectant tank, which is equipped with an ultraviolet disinfection lamp. The high-pressure water pump is located on the upper portion of the trailer body and is connected to the clean water tank, disinfectant tank, and flushing nozzle via pipes.

[0016] Furthermore, the above-mentioned solar power generation system includes a photovoltaic panel and a power storage device arranged on the upper part of the trailer body. The power storage device is connected to the first motor, the second motor, the decanter, the aerator, the ultraviolet disinfection lamp and the high-pressure water pump to provide power for them.

[0017] On the other hand, the present invention also proposes a method for using the above-mentioned environmentally friendly aquaculture transfer trailer, which is special in that it includes the following steps:

[0018] ① When the vehicle reaches its destination, the second motor is activated, releasing the wire rope. The rear door rotates and tilts about the first hinge, and the two folding sections unfold flat on the ground, erecting the foldable baffle on the rear door. The rear door unfolds to form a passageway, allowing the animals to exit the vehicle and step onto the anti-slip plate on the rear door to reach the ground. When all the animals on the lowest level have exited the vehicle, the first motor is activated, and the wire rope drives the first hinge and rear door to rise to the second floor of the vehicle. The animals then exit the vehicle and step onto the anti-slip plate on the rear door to reach the ground. When all the animals on the second floor have exited the vehicle, the first motor is activated, and the wire rope drives the first hinge and rear door to rise to the third floor of the vehicle. The animals then exit the vehicle and step onto the anti-slip plate on the rear door to reach the ground.

[0019] ② When all livestock are driven out of the carriage, start the high-pressure water pump, and the water from the disinfection water tank or the clean water tank is used to flush the interior of the carriage through the flushing water gun. The flushing water containing feces and urine flows from the groove into the collection pipe and then gathers into the sedimentation separation box.

[0020] ③ Flushing water containing feces and urine enters the sedimentation separation tank through the inlet pipe. The solids and water are separated, and the decanter decanters the clarified water from the still water surface into the anaerobic tank. The solids are discharged through the sediment discharge valve and sent to the composting site for treatment.

[0021] ④ Wastewater enters the anaerobic tank through the anaerobic tank inlet pipe. Once inside, the wastewater flows up and down along the baffles, passing through the sludge beds in each reaction chamber of the facultative, anoxic, and anaerobic sections. The sludge in the anaerobic tank moves with the up and down flow of the wastewater and the rise of biogas. The blocking effect of the filler and baffles, as well as the sedimentation of the sludge itself, reduces the sludge flow rate, resulting in a large amount of sludge being trapped in the anaerobic tank. The microorganisms in the anaerobic tank come into full contact with the organic matter in the wastewater. The facultative bacteria in the facultative anaerobic section and the heterotrophic bacteria in the anoxic and anaerobic sections hydrolyze the organic matter in the wastewater into organic acids, decomposing large organic molecules into small molecules and converting insoluble organic matter into soluble organic matter. The wastewater after anaerobic reaction is separated into mud, water and methane gas under the action of the three-phase separator of the anaerobic box. The sludge sinks to the bottom of the anaerobic box under the action of gravity, and the excess sludge is discharged through the sludge discharge valve at the bottom; the methane waste gas generated by the anaerobic box is collected and discharged through the anaerobic box gas collecting pipe; the wastewater enters the biochemical filter box through the anaerobic box overflow weir and the anaerobic box outlet pipe.

[0022] ⑤ Wastewater enters the downstream area through the water inlet pipe and water distribution pipe of the biochemical filter. The air generated by the aeration pipe and the wastewater intersect in the biochemical filler to produce a biochemical reaction. At the same time, the biochemical filler filters the wastewater. The wastewater passes through the guide plate and enters the upstream area. The filter material filters the wastewater. The solid matter generated in the downstream and upstream areas sinks to the sludge area and is discharged through the sludge discharge valve. The water treated by the biochemical filter box enters the disinfection water tank through the overflow weir of the biochemical filter box. The water is disinfected by the ultraviolet disinfection lamp and then reused.

[0023] ⑥ When grazing is finished and the animals need to move to another pasture, the rear door is opened. Starting from the top level, the animals step onto the anti-slip plate on the rear door from the ground to enter the vehicle. Next, the first motor is activated, and a steel wire rope drives the first hinge and the rear door down to the floor of the next level. The animals then step onto the anti-slip plate on the rear door from the ground to enter the vehicle. Finally, the second motor is activated, retracting the steel wire rope, causing the rear door to rotate around the first hinge and stand upright. The rear door is then secured to the vehicle wall using buckles or ropes. The vehicle is then started and transport begins.

[0024] The beneficial effects of the present invention are:

[0025] 1. The trailer can be designed with two or three layers according to the height of the livestock. When sheep are being moved, it is designed with three layers, and when cattle are being moved, it is designed with two layers, so as to maximize the use of space.

[0026] 2. The rear door of the trailer can be opened and closed, acting as a door. When folded flat, it can also serve as a staircase for livestock to get on and off the trailer.

[0027] 3. The environmentally friendly livestock transfer trailer can be added with feed and water. It can be used as a short-distance transportation tool, as well as a long-distance transfer tool. It can also be used as a livestock overnight accommodation.

[0028] 4. Treating and reusing wastewater not only avoids environmental pollution but also saves water resources, and is particularly suitable for pastures with water shortages;

[0029] 5. High vehicle transportation efficiency and low loss;

[0030] 6. Simple structure, easy to manufacture or modify, low cost; easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] As a preferred embodiment of the present invention, the excrement treatment system is arranged in the front direction of the trailer body 1 and the lower part of the clean water tank 7. The excrement treatment system includes a sedimentation separation box 8, an anaerobic box 9, a biochemical filter box 10 and a disinfection water tank; the sedimentation separation box 8, the anaerobic box 9, the biochemical filter box 10 and the disinfection water tank are connected in sequence.

[0046] Specifically, see Figure 2 The sedimentation separation box 8 is provided with a sedimentation separation box inlet pipe 801. A baffle 802 is provided inside the sedimentation separation box 8. The baffle 802 and the wall of the sedimentation separation box form a wastewater flow channel for wastewater to enter. The sedimentation separation box inlet pipe 801 is connected to the wastewater flow channel. An exhaust hole 803 is provided at the top of the sedimentation separation box, and the waste gas generated by the anaerobic reaction in the sedimentation separation box is discharged through the exhaust hole 803. A self-floating decanter 804 is provided on the water surface of the sedimentation separation box.

The bottom of the sedimentation separation box is designed as a conical structure, and a sediment discharge valve 805 is provided at the bottom of the conical structure. The sedimentation tank operates intermittently. Flushing water from the transfer trailer enters the sedimentation tank 8 through a pipeline and the sedimentation tank inlet pipe 801. The flushing water, containing feces and urine, settles inside the sedimentation tank 8, separating the solids from the water. The solids are then discharged through the sediment discharge valve 805 and sent to the composting site for processing. The settled water then flows through a decanter 804 and enters the anaerobic tank 9. The sedimentation tank lasts for 1.5 to 2 hours. Prolonged settling time can lead to anaerobic reactions in the wastewater.

[0047] Specifically, see Figure 3 The anaerobic box 9 includes an aerobic section 902, an anoxic section 903 and an anaerobic section 904 separated by multiple baffles 901. The head end of the aerobic section 902 is provided with an anaerobic box water inlet pipe 905 for supplying wastewater.

The lower portion of the baffle on the water inlet side of the anoxic section 903 and the anaerobic section 904 is provided with a 45-degree angle to avoid the impact caused by the water flow entering, thereby playing the role of buffering the water flow and evenly distributing the water. The end of the anaerobic section is provided with an anaerobic box three-phase separator 906 and an anaerobic box overflow weir 907, and the anaerobic box overflow weir 907 is connected to the anaerobic box outlet pipe. The bottoms of the facultative oxic section 902, the anoxic section 903, and the anaerobic section 904 are all designed to have a conical structure, and the conical structure is connected to the sludge discharge valve 908.

[0048] Specifically, see Figure 4The biochemical filter box 10 has a cylindrical upper portion and a conical lower portion, comprising a downflow zone 1001, an upflow zone 1002, and a sludge settling zone 1003. Downflow zone 1001 is located in the middle of the columnar structure of the biochemical filter box. A biofilter inlet pipe 1004 and a water distribution pipe 1005 are located above downflow zone 1001. Biofilter inlet pipe 1004 connects to the anaerobic chamber outlet pipe. Biochemical filler 1006 is located in the downflow zone, and an aeration pipe 1007 is located below the downflow zone. Aeration pipe 1007 connects to an aerator mounted on the outer wall of the biofilter box. A guide plate 1008 is provided at the bottom of the downstream area, and the longitudinal section of the guide plate 1008 is trumpet-shaped; the upstream area 1002 is located at the periphery of the downstream area 1001 and the upper part of the guide plate 1008, and a filter material 1009 is provided in the upstream area, and a biochemical filter box overflow weir 1010 is provided at the outlet of the upper part of the upstream area; the sludge area 1003 is located at the bottom of the biochemical filter box and at the lower part of the downstream area 1001 and the upstream area 1002, and a sludge discharge valve 1011 is provided at the bottom of the sludge area 1003.

[0049] As a preferred embodiment of the present invention, the water outlet of the biochemical filter box 10 enters a disinfection water tank, which is equipped with an ultraviolet disinfection lamp. The high-pressure water pump is installed on the upper part of the trailer body 1 and is connected to the clean water tank 7, the disinfection water tank and the flushing water gun through a pipeline.

[0050] As a preferred embodiment of the present invention, the environmentally friendly aquaculture transfer trailer also includes a solar power generation system, which includes a photovoltaic panel and a power storage device arranged on the upper part of the trailer body. The power storage device is connected to the first motor, the second motor 5, the decanter 804, the aerator, the ultraviolet disinfection lamp and the high-pressure water pump.

[0051] The method for using the above-mentioned environmentally friendly aquaculture transfer trailer has the following steps:

[0052] ① When the vehicle reaches its destination, the second motor 5 is activated, releasing the wire rope 6. The rear door 2 rotates and tilts around the first hinge 3, and the two folding sections unfold flat on the ground, erecting the foldable baffle on the rear door 2. The rear door unfolds to form a passageway, allowing the livestock to exit the vehicle and step onto the anti-skid plate on the rear door 2 to reach the ground. When all the livestock on the lowest level have exited the vehicle, the first motor is activated, and the wire rope drives the first hinge 3 and rear door 2 to rise to the floor of the second level. The livestock then exit the vehicle and step onto the anti-skid plate on the rear door 2 to reach the ground. When all the livestock on the second level have exited the vehicle, the first motor is activated, and the wire rope drives the first hinge 3 and rear door 2 to rise to the floor of the third level. The livestock then exit the vehicle and step onto the anti-skid plate on the rear door 2 to reach the ground.

[0053] ② When all the livestock are driven out of the carriage, the high-pressure water pump is started, and the water from the disinfection water tank or the clean water tank 7 is used to flush the interior of the carriage through the flushing water gun. The flushing water containing feces and urine flows from the groove into the collection pipe and then gathers into the sedimentation separation box 8.

[0054] ③ Flushing water containing feces and urine enters sedimentation separation tank 8 through sedimentation separation tank inlet pipe 801. Solids and water are separated, and decanter 804 decantes the clarified water from the still water surface into anaerobic tank 9. Solids are discharged through sediment discharge valve 805 into the composting site for processing.

[0055] ④ Wastewater enters anaerobic tank 9 through anaerobic tank inlet pipe 905. Once inside, the wastewater flows up and down along baffles 901, passing through the sludge beds in each reaction chamber of facultative oxic section 902, anoxic section 903, and anaerobic section 904. The sludge in anaerobic tank 9 moves with the upward and downward flow of the wastewater and the rise of biogas. The blocking effect of the filler and baffles, as well as the sludge's own settling, slows the sludge flow rate. Consequently, a large amount of sludge is trapped in anaerobic tank 9, allowing the microorganisms there to fully come into contact with the organic matter in the wastewater. The facultative bacteria in facultative oxic section 902 and the heterotrophic bacteria in anoxic section 903 and anaerobic section 904 hydrolyze the organic matter in the wastewater into organic acids, breaking down large organic molecules into small ones and converting insoluble organic matter into soluble ones. The wastewater after the anaerobic reaction is separated into mud, water, and methane gas under the action of the anaerobic box three-phase separator 906. The sludge sinks to the bottom of the anaerobic box under the action of gravity, and the excess sludge is discharged through the sludge discharge valve 908 at the bottom; the methane waste gas generated by the anaerobic box is collected and discharged through the anaerobic box gas collection pipe 910; the wastewater enters the biochemical filter box 10 through the anaerobic box overflow weir 907 and the anaerobic box outlet pipe.

[0056] ⑤ Wastewater enters the downstream area 1001 through the biochemical filter inlet pipe 1004 and the water distribution pipe 1005. The air generated by the aeration pipe 1007 and the wastewater intersect in the biochemical filler 1006 to generate a biochemical reaction. At the same time, the biochemical filler 1006 filters the wastewater. The wastewater passes through the guide plate 1008 and enters the upstream area 1002. The filter material 1009 filters the wastewater. The solid matter generated in the downstream area 1001 and the upstream area 1002 sinks to the sludge area 1003 and is discharged through the sludge discharge valve 1011. The water treated by the biochemical filter box 10 enters the disinfection water tank through the biochemical filter box overflow weir 1010. The water is disinfected by the ultraviolet disinfection lamp and then reused.

[0057] ⑥ When grazing is finished and the animals need to move to another pasture, rear door 2 is opened. Starting from the top level, the animals step onto the anti-slip plate on rear door 2 from the ground to enter the vehicle. Next, the first motor is activated, and the steel wire rope drives the first hinge 3 and rear door 2 down to the floor of the next level. The animals then step onto the anti-slip plate on rear door 2 from the ground to enter the vehicle. Finally, the second motor 5 is activated, retracting the steel wire rope 6, causing rear door 2 to rotate around the first hinge 3 and stand upright. A buckle or rope is then used to secure rear door 2 to the vehicle wall. The vehicle is then started and the transportation to the next pasture begins.

[0058] Finally, it should be noted that the above is only the best embodiment of the present invention, but the scope of protection of the present invention is not limited to this. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
