Description

Technical Field

[0001] This utility model relates to the field of cooling technology for periodic sewage discharge expansion containers, and in particular to a built-in cooling periodic sewage discharge expansion container. Background Technology

[0002] In existing technologies, the main function of periodic wastewater discharge expansion containers is to introduce high-temperature and high-pressure wastewater discharged from boilers into the containers. Their purpose is to effectively recover heat and working fluid from the wastewater, reduce energy waste, and at the same time lower the temperature and pressure of wastewater discharge to meet environmental protection emission requirements and improve the economic efficiency and environmental friendliness of industrial systems.

[0003] A search revealed a utility model patent with Chinese patent publication number CN219283304U, which discloses a sewage expansion container with an added sewage tank. The container includes a main body with a maintenance channel and pressure inspection port on one side. This utility model utilizes a cleaning mechanism that drives a support rod to rotate a cleaning plate, allowing the cleaning plate to scrape the inner wall of the main body. Simultaneously, it drives a rotating rod, a connecting rod, and a brush block, which in turn scrubs the inner wall of the main body. A gear and a gear ring work together to drive the rotating rod, connecting rod, and brush block to rotate, achieving both revolution around the axis and rotation on its own axis, thus improving cleaning efficiency and enhancing practicality. A cooling mechanism cools the sewage inside the main body, while a stirring rod agitates the water, and a condenser further cools the water, resulting in a uniform temperature distribution and continuous cooling for better cooling performance. Although the sewage expansion container with added sewage tank in the above-mentioned utility model can drive the sprocket to rotate through the rotating rod one, thereby driving the chain to drive the sprocket two, which in turn drives the rotating rod two to drive the stirring rod to rotate, thereby stirring the cooling water and cooling the water through the condenser, making the temperature distribution of the cooling water more uniform, the above-mentioned utility model only relies on the coolant to cool the sewage. The single cooling method leads to low cooling efficiency. In addition, the flow of cooling water in the cooling pipe can easily cause the sewage temperature to stratify inside the expansion container body, resulting in poor cooling uniformity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a built-in cooling periodic sewage discharge expansion container.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A built-in cooling periodic sewage expansion container includes a sewage expansion container body, a connecting plate fixedly connected to the bottom of the sewage expansion container body, a vacuum pump fixedly connected to the top of the connecting plate, the suction end of the vacuum pump communicating with the sewage expansion container body, a stirring and cooling mechanism provided at the bottom of the connecting plate, and a preliminary cooling mechanism provided on the outer surface of the sewage expansion container body.

[0007] As a further improvement of this utility model: an air vent valve is fixedly connected to the top of the main body of the sewage expansion container, and the air vent valve is connected to the top of the main body of the sewage expansion container.

[0008] As a further embodiment of this utility model: the stirring and cooling mechanism includes an isolation sleeve one, a motor, an outer magnet, an inner magnet, an isolation sleeve two, and a stirring rod, and the isolation sleeve one is fixedly connected to the bottom of the connecting plate.

[0009] As a further embodiment of this utility model: the motor is fixedly connected to the bottom of the first isolation sleeve, and the motor output end passes through one side of the first isolation sleeve. The outer magnet is fixedly connected to the motor output end. The second isolation sleeve is fixedly connected to the inner wall of the main body of the sewage expansion container. The stirring rod is rotatably connected to the inner wall of the second isolation sleeve, and the inner magnet is fixedly connected to one end of the stirring rod.

[0010] As a further embodiment of this utility model: the preliminary cooling mechanism includes a connecting ring, a rotating rod, a jacket, a fan blade, a coil, a valve, a circulating pump, a base, and a water tank, and the connecting ring is fixedly connected to the inner wall of the water inlet end of the main body of the sewage expansion container.

[0011] As a further embodiment of this utility model: the jacket is fixedly connected to one side of the water inlet, the rotating rod is rotatably connected to one side of the connecting ring, and the rotating rod is located inside the jacket. Multiple sets of fan blades are evenly installed on the outer wall of the rotating rod, and the coil is fixedly connected to the jacket layer.

[0012] As a further embodiment of this utility model: the valve is fixedly connected to the jacket and the valve is in communication with the jacket; the base is fixedly connected to one side of the connecting plate; the water tank is fixedly connected to one side of the base; the circulation pump is fixedly connected to the top of the base, and the input end of the circulation pump is in communication with the water tank; the output end of the circulation pump is in communication with the coil, and one end of the coil is in communication with the water tank.

[0013] Compared with the prior art, this utility model provides a built-in cooling periodic sewage discharge expansion container, which has the following beneficial effects:

[0014] 1. First, external sewage is pumped into the preliminary cooling mechanism, which pre-cools the sewage. The pre-cooled sewage then flows into the main body of the sewage expansion container. A vacuum pump is then activated to evacuate the interior of the container to a vacuum state. Once the container reaches the set vacuum level, a stirring cooling mechanism is activated to increase the contact area between the sewage and the vacuum environment, accelerating the vaporization process and promoting turbulent flow of the liquid within the container, resulting in a more uniform temperature distribution. Finally, the vaporized steam is discharged through the vent valve, and the cooled sewage is discharged from the outlet of the sewage expansion container. This forms a multi-stage cooling system. The vacuum pump creates a vacuum within the sewage expansion container to lower the boiling point of water, and the stirring cooling mechanism further increases the contact area between the sewage and the vacuum environment, improving cooling efficiency.

[0015] 2. After the main body of the sewage expansion container is evacuated to a vacuum state by the vacuum pump, the motor is started. The motor output drives the outer magnet to start rotating. The rotating magnetic field of the outer magnet drives the inner magnet to rotate synchronously through magnetic force, and drives the stirring rod to rotate at the connection of the isolation sleeve. Thus, the vacuum pump makes the main body of the sewage expansion container reach a vacuum state, thereby lowering the boiling point of the wastewater and causing vaporization to carry away a large amount of heat. The rotation of the stirring rod causes the sewage to form strong turbulence, increasing the contact area between the sewage and the vacuum environment, accelerating the vaporization and heat absorption process of the sewage. At the same time, stirring makes the internal temperature of the sewage quickly uniform, avoiding the problem of insufficient and uneven cooling caused by local overheating.

[0016] 3. After connecting the sewage pipe to the valve, when the sewage is pumped into the main body of the sewage expansion container, it flows through the jacket and impacts the fan blades on the outer wall of the rotating rod, causing the rotating rod to rotate at the connection point of the connecting ring. At the same time, the circulation pump is started to draw cooling water from the water tank and send it into the coil in the jacket layer. The rotation of the rotating rod and the fan blades causes the sewage in the jacket to form turbulence, breaking the boundary layer and increasing the convective heat transfer coefficient between the sewage and the coil. After absorbing heat in the coil, the cooling water flows back to the water tank, forming a water circulation. The cooled water enters the main body of the sewage expansion container through the gap of the connecting ring. Thus, the flow energy of the sewage itself drives the fan blades to rotate, improving the heat exchange efficiency. The rotation and turbulence of the coil and the jacket further improve the heat transfer coefficient, thereby initially reducing the temperature of the sewage.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] A built-in cooling periodic sewage discharge expansion container, such as Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 5 As shown, the system includes a sewage expansion container body 1. A connecting plate 2 is fixedly connected to the bottom of the sewage expansion container body 1, and a vacuum pump 3 is fixedly connected to the top of the connecting plate 2. The suction end of the vacuum pump 3 is connected to the sewage expansion container body 1. An exhaust valve 4 is fixedly connected to the top of the sewage expansion container body 1 and is connected to the top of the sewage expansion container body 1. A stirring and cooling mechanism 5 is provided at the bottom of the connecting plate 2, and a preliminary cooling mechanism 6 is provided on the outer surface of the sewage expansion container body 1. The vacuum pump 3 is model SHZ-D(III).

[0028] First, external sewage is pumped into the preliminary cooling mechanism 6, which pre-cools the sewage. Then, the pre-cooled sewage flows into the main body 1 of the sewage expansion container. Immediately afterward, the vacuum pump 3 is activated to evacuate the inside of the main body 1 of the sewage expansion container to a vacuum state. Once the main body 1 of the sewage expansion container reaches the set vacuum level, the stirring cooling mechanism 5 is activated to increase the contact area between the sewage and the vacuum environment, accelerate the vaporization process, and promote the turbulent movement of the liquid inside the container, making the temperature distribution more uniform. Finally, the vapor generated by vaporization is discharged through the vent valve 4. The sewage that has completed the cooling treatment is discharged from the outlet of the main body 1 of the sewage expansion container. Thus, a multi-stage cooling system is formed. The vacuum pump 3 creates a vacuum state inside the main body 1 of the sewage expansion container to lower the boiling point of water, and the stirring cooling mechanism 5 further cools the sewage, increasing the contact area between the sewage and the vacuum environment and improving the cooling efficiency.

[0029] To further cool the wastewater inside the main body 1 of the sewage discharge expansion container, such as... Figure 3 and Figure 4 As shown, the stirring and cooling mechanism 5 includes an isolation sleeve 501, a motor 502, an outer magnet 503, an inner magnet 504, an isolation sleeve 505, and a stirring rod 506. The isolation sleeve 501 is fixedly connected to the bottom of the connecting plate 2, the motor 502 is fixedly connected to the bottom of the isolation sleeve 501, and the output end of the motor 502 passes through one side of the isolation sleeve 501. The outer magnet 503 is fixedly connected to the output end of the motor 502. The isolation sleeve 505 is fixedly connected to the inner wall of the sewage expansion container body 1. The stirring rod 506 is rotatably connected to the inner wall of the isolation sleeve 505, and the inner magnet 504 is fixedly connected to one end of the stirring rod 506.

[0030] When the inside of the sewage expansion container 1 is evacuated to a vacuum state by the vacuum pump 3, the motor 502 is started. The output end of the motor 502 drives the outer magnet 503 to start rotating. The rotating magnetic field of the outer magnet 503 drives the inner magnet 504 to rotate synchronously through magnetic force, and drives the stirring rod 506 to rotate at the connection of the isolation sleeve 2 505. Thus, the vacuum pump 3 makes the sewage expansion container 1 reach a vacuum state, thereby lowering the boiling point of the wastewater and causing vaporization to carry away a large amount of heat. The rotation of the stirring rod 506 causes the sewage to form strong turbulence, increasing the contact area between the sewage and the vacuum environment, accelerating the vaporization and heat absorption process of the sewage. At the same time, stirring makes the internal temperature of the sewage quickly uniform, avoiding the problem of insufficient and uneven cooling caused by local overheating.

[0031] In order to initially cool the sewage discharged into the main body 1 of the sewage expansion container, such as Figure 5 As shown, the preliminary cooling mechanism 6 includes a connecting ring 601, a rotating rod 602, a jacket 603, fan blades 604, a coil 605, a valve 606, a circulating pump 607, a base 608, and a water tank 609. The connecting ring 601 is fixedly connected to the inner wall of the inlet end of the sewage expansion container body 1, the jacket 603 is fixedly connected to one side of the inlet end, the rotating rod 602 is rotatably connected to one side of the connecting ring 601, and the rotating rod 602 is located inside the jacket 603. Multiple sets of fan blades 604 are evenly installed on the outer wall of the rotating rod 602, and the coil... 605 is fixedly connected to the interlayer of the jacket 603, valve 606 is fixedly connected to the jacket 603 and is connected to the jacket 603, base 608 is fixedly connected to one side of the connecting plate 2, water tank 609 is fixedly connected to one side of the base 608, circulation pump 607 is fixedly connected to the top of the base 608, and the input end of circulation pump 607 is connected to the water tank 609, the output end of circulation pump 607 is connected to the coil 605, and one end of coil 605 is connected to the water tank 609. The model of circulation pump 607 is CR5-4.

[0032] After the sewage pipe is connected to the valve 606, when the sewage is pumped into the main body 1 of the sewage expansion container, it flows through the jacket 603 and impacts the fan blade 604 on the outer wall of the rotating rod 602, causing the rotating rod 602 to rotate at the connection point of the connecting ring 601. At the same time, the circulation pump 607 is started to draw cooling water from the water tank 609 and send it into the coil 605 in the jacket 603.

[0033] The rotation of the rotating rod 602 and the fan blade 604 causes the sewage in the jacket 603 to form turbulence, breaking the boundary layer and increasing the convective heat transfer coefficient between the sewage and the coil 605. After absorbing heat in the coil 605, the cooling water flows back to the water tank 609, forming a water circulation. The cooled warm water enters the main body 1 of the sewage expansion container through the gap of the connecting ring 601. Thus, the flow energy of the sewage itself drives the fan blade 604 to rotate, improving the heat exchange efficiency. The coil 605 and the jacket 603 work together to rotate and turbulent the flow, thereby improving the heat transfer coefficient and initially reducing the temperature of the sewage.

[0034] Working principle: First, external sewage is pumped into the preliminary cooling mechanism 6, which pre-cools the sewage. Then, the pre-cooled sewage flows into the main body 1 of the sewage discharge expansion container. Immediately afterward, the vacuum pump 3 is activated to evacuate the interior of the main body 1 to a vacuum state. Once the set vacuum level is reached, the stirring and cooling mechanism 5 is activated to increase the contact area between the sewage and the vacuum environment, accelerating the vaporization process and promoting turbulent flow of the liquid within the container, resulting in a more uniform temperature distribution. Finally, the vaporized steam is discharged through the vent valve 4, and the cooled sewage is discharged from the outlet of the main body 1 of the sewage discharge expansion container.

[0035] When the inside of the sewage expansion container 1 is evacuated to a vacuum state by the vacuum pump 3, the motor 502 is started. The output end of the motor 502 drives the outer magnet 503 to start rotating. The rotating magnetic field of the outer magnet 503 drives the inner magnet 504 to rotate synchronously through magnetic force, and drives the stirring rod 506 to rotate at the connection of the isolation sleeve 2 505.

[0036] After the sewage pipe is connected to the valve 606, when the sewage is pumped into the main body 1 of the sewage expansion container, it flows through the jacket 603 and impacts the fan blade 604 on the outer wall of the rotating rod 602, causing the rotating rod 602 to rotate at the connection point of the connecting ring 601. At the same time, the circulation pump 607 is started to draw cooling water from the water tank 609 and send it into the coil 605 in the jacket 603.

[0037] The rotation of the rotating rod 602 and the fan blade 604 causes the sewage in the jacket 603 to form turbulence, breaking the boundary layer and increasing the convective heat transfer coefficient between the sewage and the coil 605. After absorbing heat in the coil 605, the cooling water flows back to the water tank 609, forming a water circulation. The cooled warm water enters the main body 1 of the sewage expansion container through the gap of the connecting ring 601.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
