Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment and recycling, and in particular to a wastewater heat energy recovery device. Background Technology

[0002] When treating wastewater such as domestic sewage and industrial wastewater, the sewage usually contains a high amount of heat energy. In order to avoid energy waste, it is very important to recover the heat energy of the sewage. Therefore, certain devices are needed. The sewage heat energy recovery device is a device that uses the residual heat contained in the sewage to recover and reuse energy, and has significant energy saving and emission reduction effects.

[0003] Chinese Patent Application No. CN201921428780.4 discloses a boiler wastewater heat energy recovery device. In this design, the cylinder is moved outside the fins by holding the handle, and the drive motor is turned on. The drive motor drives the active gear to rotate, which in turn drives two driven gears to rotate. This ultimately drives two rotating rods with densely distributed cleaning bristles on the circumferential sides to clean the deposited impurities on the fins, preventing impurities from accumulating in the grooves of the fins and ensuring the heat exchange efficiency and continuous normal operation of the fins.

[0004] Existing wastewater heat recovery devices have certain drawbacks. First, because wastewater contains impurities, if it is not effectively filtered, it can lead to heat exchanger blockage and reduced heat exchange efficiency. However, the filter structures used in existing wastewater heat recovery devices are mostly relatively fixed, which makes it inconvenient to disassemble and maintain the filter structure. This increases the downtime for maintenance and affects the efficiency of the wastewater heat recovery device. Therefore, we propose a wastewater heat recovery device. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a wastewater heat energy recovery device. By setting irregularly shaped slots and arc-shaped clamps, the wastewater heat energy recovery device can be designed to be detachable, allowing maintenance personnel to quickly remove the filter device, making it easier to clean scale or replace filter elements, reducing downtime. Furthermore, the detachable and easy-to-connect structure allows for flexible adaptation to different application environments by changing different types of filter elements or mesh sizes when encountering different wastewater impurities. This improves the convenience of the wastewater heat energy recovery device in heat recovery operations.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A wastewater heat recovery device includes a treatment tank, inside which a filter chamber is provided. A pair of filter elements are movably connected inside the filter chamber. A pair of handles are fixedly connected to the upper end of each filter element. A symmetrically distributed mounting frame is fixedly connected to the inner wall of the filter chamber. An assembly frame is fixedly connected to both ends of the filter element. An irregularly shaped slot is opened at the inner end of the assembly frame, and an arc-shaped clamping head is engaged at the inner end of the irregularly shaped slot.

[0008] By installing irregularly shaped slots and arc-shaped clamps, the convenience of heat recovery work in this wastewater heat energy recovery device can be improved.

[0009] Furthermore, an adjusting rod is fixedly connected to the rear end of the arc-shaped clamp head. The adjusting rod has a T-shaped structure and passes through the mounting frame and extends into the interior of the processing box.

[0010] By installing an adjusting rod, a connecting structure can be formed at the outer end of the arc-shaped chuck, making the position adjustment of the arc-shaped chuck more stable.

[0011] Furthermore, a reset ring is fitted onto the outer end of the adjusting rod, and an adjusting groove is provided on the inner end of the mounting bracket.

[0012] By installing a reset ring, it becomes easier to engage and disengage the curved chuck head from the irregularly shaped slot.

[0013] Furthermore, a guide ring is slidably connected to the inner end of the adjusting groove, and the guide ring is located at the outer end of the adjusting rod.

[0014] By installing guide rings and adjustment grooves, the engagement and disengagement of the arc-shaped clamps can be made more convenient.

[0015] Furthermore, a connecting cover is connected to the top of the treatment box via a snap-fit ​​mechanism, a sewage pipe is fixedly connected to the top of the connecting cover, and a flow meter is fixedly connected to the outer end of the sewage pipe.

[0016] The practicality of the device can be improved by installing a flow meter.

[0017] Furthermore, a feed pipe is fixedly connected to the bottom end of the filter chamber, and a solenoid valve is fixedly connected to the outer end of the feed pipe.

[0018] By installing a feed pipe and a solenoid valve, the structure of this device can be made more convenient to use.

[0019] Furthermore, the inner end of the processing box has multiple guide plates arranged in a staggered manner, the heat exchange chamber inside the processing box is equipped with heat exchange tubes, and the right end of the processing box is fixedly connected to a conveying pipe.

[0020] The heat exchange efficiency of the recovery device can be improved by installing a baffle plate.

[0021] Furthermore, a connecting valve is installed at the outer end of the conveying pipe, and a flow meter is movably connected to the outside of the connecting valve. The flow meter is located at the outer end of the conveying pipe, and a heat storage device is fixedly connected to the other end of the conveying pipe away from the processing box.

[0022] Installing a delivery pipe and flow meter 2 can help monitor the heat recovery efficiency of the device.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. By setting up irregularly shaped slots and arc-shaped clamps, when the device is performing heat recovery, a pair of filter elements with different pore sizes can perform multi-stage treatment of sewage. When maintenance is required after long-term operation, pulling a pair of handles will move the filter elements. Under the force, the adjusting rod and arc-shaped clamps will separate from the irregularly shaped slots. The special structure of the irregularly shaped slots allows the arc-shaped clamps to be easily moved out with force. When the arc-shaped clamps are connected to the mounting frame, they can also be locked in place. This allows for convenient maintenance and cleaning of the filter elements. The detachable design of this sewage heat recovery device allows maintenance personnel to quickly remove the filter device, making it easier to clean scale or replace filter elements, reducing downtime. The detachable and easy-to-lock structure also allows for flexible adaptation to different application environments by changing different types of filter elements or mesh sizes when encountering different sewage impurities. This improves the convenience of the sewage heat recovery device in performing heat recovery.

[0025] 2. By installing flow meter one, when sewage is transported into the treatment tank through the sewage pipe, flow meter one can monitor the changes in sewage flow in real time, thereby dynamically grasping the inflow of sewage and providing accurate operating data for the heat recovery process, thus improving the practicality of the device.

[0026] 3. By setting up guide plates, multiple staggered guide plates are located outside the heat exchange tubes, which can make the sewage form a more tortuous flow path in the heat exchange chamber. This is beneficial to improving the contact efficiency between the sewage and the surface of the heat exchange tubes, avoiding the phenomenon of sewage bypassing part of the heat exchange tubes, improving the utilization rate of the heat exchange tubes, and improving the heat exchange effect of the recovery device.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0035] Reference Figure 1-5 As shown, a wastewater heat energy recovery device in a preferred embodiment of the present invention includes a treatment tank 1. A filter chamber 2 is provided inside the treatment tank 1. A pair of filter elements 14 are movably connected inside the filter chamber 2. A pair of handles 15 are fixedly connected to the upper end of each filter element 14. A symmetrically distributed mounting frame 16 is fixedly connected to the inner wall of the filter chamber 2. An assembly frame 17 is fixedly connected to both ends of the filter element 14. An irregularly shaped slot 18 is opened at the inner end of the assembly frame 17. An arc-shaped clamp head 19 is snapped into the inner end of the irregularly shaped slot 18.

[0036] Reference Figure 2-4 As shown, further, an adjusting rod 20 is fixedly connected to the rear end of the arc-shaped clamp 19. The adjusting rod 20 has a T-shaped structure and passes through the mounting frame 16 and extends into the interior of the processing box 1.

[0037] Reference Figure 2-4 As shown, further, a reset ring 21 is sleeved on the outer end of the adjusting rod 20, and an adjusting groove 22 is opened on the inner end of the mounting bracket 16.

[0038] Reference Figure 2-3 As shown, a guide ring 23 is slidably connected to the inner end of the adjusting groove 22, and the guide ring 23 is located at the outer end of the adjusting rod 20.

[0039] By installing a pair of filter elements 14 with different pore sizes, wastewater can be treated in multiple stages. When maintenance is required after prolonged operation, pulling the handles 15 moves the filter elements 14. Under this force, the adjusting rod 20 and the arc-shaped clamp 19 separate from the irregular groove 18. The special structure of the irregular groove 18 allows the arc-shaped clamp 19 to be easily and forcefully removed. Furthermore, when the arc-shaped clamp 19 is connected to the mounting bracket 17, it can be locked in place. When the filter element 14 moves outward, the arc-shaped clamp 19 contacts the interior of the irregular groove 18, creating pressure. At this time, the force of the reset ring 21 allows the adjusting rod 20 to be easily adjusted in position. And when the arc-shaped clamp 19 loses external force, the elastic force of the reset ring 21 also allows the arc-shaped clamp 19 and... The adjusting rod 20 is reset and snapped into the irregularly shaped slot 18, making it easier to engage and disengage the arc-shaped clamp 19 from the irregularly shaped slot 18. The guide ring 23 can move together with the adjusting rod 20, so that the guide ring 23 slides inside the adjusting groove 22. The adjusting groove 22 restricts and guides the guide ring 23, preventing the adjusting rod 20 and the guide ring 23 from flipping or shifting during adjustment. This allows the filter element 14 to be easily maintained and cleaned. The wastewater heat energy recovery device has a detachable design, which allows maintenance personnel to quickly remove the filter device, remove scale, or replace the filter element 14, reducing downtime. The detachable and easy-to-engage structure allows for flexible adaptation to different application environments by changing different types of filter elements 14 or mesh sizes when the wastewater impurities are different in certain situations.

[0040] Reference Figure 1 As shown, further, the top of the treatment box 1 is connected to a connecting cover 3 by a snap-fit ​​mechanism, the top of the connecting cover 3 is fixedly connected to a sewage pipe 4, and the outer end of the sewage pipe 4 is fixedly connected to a flow meter 5.

[0041] Reference Figure 1-2 As shown, further, a feed pipe 6 is fixedly connected to the bottom end of the filter chamber 2, and a solenoid valve 7 is fixedly connected to the outer end of the feed pipe 6.

[0042] Reference Figure 1 , Figure 2 and Figure 5 As shown, further, multiple guide plates 8 are staggered at the inner end of the processing box 1, heat exchange tubes 9 are provided in the heat exchange chamber inside the processing box 1, and a conveying pipe 11 is fixedly connected to the right end of the processing box 1.

[0043] Reference Figure 1-2As shown, a connecting valve 10 is installed at the outer end of the conveying pipe 11, and a flow meter 12 is movably connected to the outside of the connecting valve 10. The flow meter 12 is located at the outer end of the conveying pipe 11, and a heat storage device 13 is fixedly connected to the other end of the conveying pipe 11 away from the processing box 1.

[0044] As sewage is transported into the treatment tank 1 via sewage pipe 4, flow meter 5 monitors the sewage flow rate in real time, allowing for dynamic control of the sewage inflow and providing accurate operational data for the heat recovery process. Solenoid valve 7 is electrically connected to the external controller of the treatment tank 1. After multiple filtration components complete filtration, solenoid valve 7 activates the discharge pipe 6 to discharge sewage for heat exchange, preventing incomplete filtration from leading to impurities adhering to the heat exchange tube 9 and hindering normal heat exchange. Multiple staggered guide plates 8 are located at the heat exchange... The exterior of the heat pipe 9 allows the wastewater to form a more tortuous flow path within the heat exchange chamber, which is beneficial for improving the contact efficiency between the wastewater and the surface of the heat pipe 9, preventing the wastewater from bypassing part of the heat pipe 9, and improving the utilization rate of the heat pipe 9. After the heat pipe 9 has exchanged heat, the delivery pipe 11 directly introduces the heat medium after the heat exchange of the heat pipe 9 into the heat storage device 13, which can store the indirectly obtained heat in a timely manner and avoid heat energy waste. With the flow meter 12, the flow rate of hot water from the heat pipe 9 to the heat storage device 13 can be accurately measured, which helps to monitor the heat recovery efficiency of the device.

[0045] Specific implementation process: When the device is in use, sewage is transferred through sewage pipe 4 into the treatment tank 1. During the transfer, flow meter 5 can monitor the sewage flow rate in real time, thereby dynamically controlling the inflow of sewage and providing accurate operating data for the heat recovery process. The sewage first enters the filter chamber 2. Inside the filter chamber 2, a pair of filter elements 14 with different pore sizes can perform multi-stage treatment on the sewage. After filtration, the solenoid valve 7 is activated. The solenoid valve 7 is electrically connected to the controller outside the treatment tank 1. After multiple filter elements have completed filtration, the solenoid valve 7 activates the discharge pipe 6 to discharge sewage for heat exchange. Upon entering the heat exchange chamber, multiple staggered guide plates 8 are located outside the heat exchange tubes 9, which allows the wastewater to form a more tortuous flow path within the heat exchange chamber. This improves the contact efficiency between the wastewater and the surface of the heat exchange tubes 9, prevents the wastewater from bypassing part of the heat exchange tubes 9, and increases the utilization rate of the heat exchange tubes 9. After the heat exchange tubes 9 have exchanged heat, the delivery pipe 11 directly introduces the heat medium after heat exchange into the heat storage device 13. This allows the indirectly obtained heat to be stored in a timely manner, avoiding heat energy waste. In conjunction with the flow meter 12, the flow rate of hot water from the heat exchange tubes 9 to the heat storage device 13 is accurately controlled, while the wastewater is discharged by the drain pipe at the bottom of the treatment tank 1.

[0046] Finally, when the filter element 14 requires maintenance after prolonged operation, pulling the pair of handles 15 will move the filter element 14. Under the force, the adjusting rod 20 and the arc-shaped clamp 19 will separate from the irregular groove 18. The special structure of the irregular groove 18 allows the arc-shaped clamp 19 to be easily moved out with force. Under the force, the arc-shaped clamp 19 contacts the inside of the irregular groove 18 and generates pressure. At this time, the force of the reset ring 21 allows the adjusting rod 20 to be easily adjusted in position. And when the arc-shaped clamp 19 loses its external function... After the force is applied, the elastic force of the reset ring 21 can also reset and engage the arc-shaped clamp 19 and the adjusting rod 20 inside the irregular groove 18. Furthermore, when the arc-shaped clamp 19 is connected to the mounting frame 17, it can also be engaged and fixed. This allows the filter element 14 to be easily maintained during cleaning. The detachable design of this wastewater heat recovery device allows maintenance personnel to quickly remove the filter device, clean the scale, or replace the filter element 14, reducing downtime and making the device more convenient to use.
