Description

A heat recovery device Technical Field

[0001] This utility model relates to the field of industrial energy-saving and environmental protection equipment technology, and in particular to a heat recovery device. Background Technology

[0002] A heat recovery device is a device used to recover waste heat generated in industrial production or other processes and convert it into usable energy, which helps to achieve the goals of energy conservation and emission reduction, reducing production costs and improving energy efficiency.

[0003] A search revealed Chinese Patent Publication No. CN221975863U, which discloses a heat recovery and utilization device, including a lower base and a heat exchange mechanism. The lower base has support frames evenly arranged on its upper end, with an insulation barrel fixedly connected between the upper surfaces of the four support frames. The heat exchange mechanism includes an air inlet pipe, a heat exhaust pipe, and heat dissipation fins. The heat dissipation fins are evenly spaced between the inner surfaces of the insulation barrel. The air inlet pipe runs through the middle of each heat dissipation fin, and the heat exhaust pipe is located on the outer surface of the air inlet pipe. The outer surface of the heat exhaust pipe is fixedly connected to the through-hole of each heat dissipation fin, and the upper end of the heat exhaust pipe is connected to the upper surface of the insulation barrel. This heat recovery and utilization device recovers and utilizes heat by heating water with the high-temperature air generated during fertilizer production. Through the dual utilization of heating and insulation, it maximizes the utilization of heat from the high-temperature air, thus improving the efficiency of high-temperature air utilization.

[0004] Existing heat recovery devices typically install temperature sensors at key locations to monitor temperature changes in hot and cold fluids in real time. However, these devices usually use a single filter with a fixed pore size when filtering waste liquid, making it difficult to filter impurities of different particle sizes simultaneously. Furthermore, after prolonged use, impurities can easily clog the filter, leading to decreased filtration efficiency and increased cleaning and maintenance costs. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a heat recovery device, which aims to improve the problem that existing heat recovery devices are unable to filter impurities of different particle sizes at the same time, resulting in decreased filtration efficiency and increased cleaning and maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat recovery device, comprising a filter chamber, a cable tray fixedly connected to the outer wall of the filter chamber, a connecting pipe fixedly connected to the inside of the cable tray, a water pipe fixedly connected to the outer wall of the connecting pipe, a fixing frame disposed inside the filter chamber, a filter assembly disposed inside the fixing frame, a second connecting plate slidably connected to the inside of the fixing frame, a middle filter screen fixedly connected to the outer wall of the second connecting plate, the outer wall of the middle filter screen slidably connected to the inside of the fixing frame, a third connecting plate slidably connected to the inside of the fixing frame, a fine filter screen fixedly connected to the outer wall of the third connecting plate, and the outer wall of the fine filter screen slidably connected to the inside of the fixing frame.

[0007] The above technical solution works as follows: First, a coarse filter removes large particles of impurities from the wastewater. Then, a medium filter removes medium-sized particles. Since the medium filter is made of porous ceramic material, it can also adsorb some dissolved impurities in the wastewater. Finally, a fine filter removes tiny particles and colloidal impurities. When the coarse, medium, and fine filters become clogged, they can be backwashed through a backwash pipe installed at the bottom of the filter chamber to flush out the clogged impurities. The cooperation between the coarse, medium, and fine filters allows for the simultaneous filtration of impurities of different sizes in the wastewater, thereby improving filtration efficiency.

[0008] As a further description of the above technical solution:

[0009] The filter assembly includes a connecting plate, the outer wall of which is slidably connected to the inside of the fixed frame, and a coarse filter screen is fixedly connected to the outer wall of the connecting plate. The outer wall of the coarse filter screen is slidably connected to the inside of the fixed frame.

[0010] The above technical solution involves first installing the connecting plate inside the fixed frame. Since the connecting plate and the coarse filter screen are fixedly connected, the coarse filter screen can be quickly installed inside the fixed frame.

[0011] As a further description of the above technical solution:

[0012] The fixed frame has a sliding groove inside, and the connecting plate is slidably connected to the inside of the fixed frame through the sliding groove.

[0013] Through the above technical solution: the slide groove is used to limit the running trajectory of the connecting plate, so as to realize the quick installation of the connecting plate and improve the stability of the connecting plate during operation.

[0014] As a further description of the above technical solution:

[0015] The fixed frame has a second sliding groove inside, and the second connecting plate is slidably connected to the inside of the fixed frame through the second sliding groove.

[0016] The above technical solution is used to improve the stability of the connecting plate 2 during sliding.

[0017] As a further description of the above technical solution:

[0018] The fixed frame has a sliding groove three inside, and the connecting plate three is slidably connected to the inside of the fixed frame through the sliding groove three.

[0019] Through the above technical solution, the connecting plate three can be quickly installed inside the fixed frame through the sliding groove three.

[0020] As a further description of the above technical solution:

[0021] A support frame is fixedly connected to the upper surface of the fixed frame. A flip plate is rotatably connected to the outer wall of the support frame. A support block is attached to the outer wall of the flip plate. The outer wall of the support block is fixedly connected to the outer wall of the filter chamber. A transmission component is provided inside the support block. A rotating plate is fixedly connected to the outer wall of the transmission component. The outer wall of the flip plate slides on the outer wall of the rotating plate.

[0022] The above technical solution involves flipping the flip plate to fit it against the support block, and then rotating the transmission component to drive the rotating plate to rotate, so that the rotating plate and the flip plate are misaligned. By rotating the rotating plate, the fixing frame can be quickly fixed or disassembled, which facilitates the removal of the filter screen later.

[0023] As a further description of the above technical solution:

[0024] The transmission assembly includes a rotating column, the outer wall of which is rotatably connected to the inside of a support block, and a second rotating plate fixedly connected to the outer wall of the rotating column, which is also fixedly connected to the inside of the first rotating plate.

[0025] The above technical solution is used to drive the rotating column to rotate when the rotating plate 2 rotates, thereby driving the rotating plate 1 to rotate.

[0026] As a further description of the above technical solution:

[0027] The inside of the flip plate is provided with a groove, and the flip plate is slidably connected to the outer wall of the rotating plate through the groove.

[0028] The above technical solution achieves the effect of limiting the flipping of the rotating plate by making it misaligned with the groove when the rotating plate rotates.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the coarse, medium and fine filters work together to filter different impurity particles in wastewater, thereby improving filtration efficiency. Furthermore, when the coarse, medium and fine filters become clogged, they can be backwashed through the backwash pipe, thus improving filtration efficiency while reducing cleaning and maintenance costs.

[0031] 2. In this utility model, the flip plate is first flipped so that it fits against the support block. Then, the second rotating plate is rotated to drive the rotating column to rotate, which in turn drives the first rotating plate to rotate. When the first rotating plate rotates, it will limit the flip plate, thereby achieving the effect of facilitating the quick installation and disassembly of the fixing frame by the operator.

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Referring to Figures 1-3, one embodiment of this utility model is provided: a heat recovery device, including a filter chamber 1, a cable tray 2 fixedly connected to the outer wall of the filter chamber 1, a connecting pipe 3 fixedly connected to the inside of the cable tray 2, a water pipe 4 fixedly connected to the outer wall of the connecting pipe 3, a fixing frame 5 provided inside the filter chamber 1, a filter assembly 6 provided inside the fixing frame 5, a connecting plate 8 slidably connected inside the fixing frame 5, a middle filter screen 7 fixedly connected to the outer wall of the connecting plate 8, the outer wall of the middle filter screen 7 slidably connected to the inside of the fixing frame 5, a connecting plate 10 slidably connected inside the fixing frame 5, a fine filter screen 9 fixedly connected to the outer wall of the connecting plate 10, and the outer wall of the fine filter screen 9 slidably connected to the inside of the fixing frame 5;

[0041] Specifically, within the filter chamber 1 of the waste liquid recovery device, a three-layer filtration structure is sequentially arranged along the waste liquid flow direction: a filter assembly 6, a medium filter 7, and a fine filter 9. The filter assembly 6 uses a metal wire mesh with a large pore size to intercept larger particles of impurities in the waste liquid. The medium filter 7 uses a porous ceramic material with a moderate pore size to filter medium-sized impurities and has a certain adsorption capacity, capable of adsorbing some soluble impurities. The fine filter 9 uses a polymer filter membrane with extremely small pore size to filter tiny particles and some colloidal impurities. The filter chamber 1 is equipped with a backwashing pipe. When the filter is clogged, high-pressure clean water can be injected into the filter chamber through the backwashing pipe to backwash the filter, flushing out the clogged impurities and restoring the filter's filtration performance. Through the cooperation between the filter assembly 6, the medium filter 7, and the fine filter 9, the filtration efficiency is improved, the frequency of filter clogging is reduced, maintenance costs are lowered, and high-quality waste liquid is provided for subsequent resource recovery.

[0042] Referring to Figures 2-4, the filter assembly 6 includes a connecting plate 602, the outer wall of the connecting plate 602 is slidably connected to the inside of the fixing frame 5, and a coarse filter screen 601 is fixedly connected to the outer wall of the connecting plate 602. The outer wall of the coarse filter screen 601 is slidably connected to the inside of the fixing frame 5.

[0043] Specifically, the coarse filter 601 is used to intercept larger particles of impurities in the waste liquid, preventing clogging of subsequent filter screens.

[0044] Referring to Figures 3 and 4, the inside of the fixing frame 5 is provided with a first sliding groove 11, and the first connecting plate 602 is slidably connected to the inside of the fixing frame 5 through the first sliding groove 11; the inside of the fixing frame 5 is provided with a second sliding groove 12, and the second connecting plate 8 is slidably connected to the inside of the fixing frame 5 through the second sliding groove 12; the inside of the fixing frame 5 is provided with a third sliding groove 13, and the third connecting plate 10 is slidably connected to the inside of the fixing frame 5 through the third sliding groove 13.

[0045] Specifically, slide groove 11, slide groove 2 12 and slide groove 3 13 are used to limit the sliding trajectory of connecting plate 1 602, connecting plate 2 8 and connecting plate 3 10, improve the stability of connecting plate 1 602, connecting plate 2 8 and connecting plate 3 10 when sliding, and facilitate the later installation of the filter device.

[0046] Referring to Figures 3-5, a support frame 14 is fixedly connected to the upper surface of the fixed frame 5. A flip plate 15 is rotatably connected to the outer wall of the support frame 14. A support block 18 is attached to the outer wall of the flip plate 15. The outer wall of the support block 18 is fixedly connected to the outer wall of the filter chamber 1. A transmission assembly 17 is provided inside the support block 18. A rotating plate 16 is fixedly connected to the outer wall of the transmission assembly 17. The outer wall of the flip plate 15 slides on the outer wall of the rotating plate 16.

[0047] Specifically, when it is necessary to install and fix the fixing frame 5, first place the fixing frame 5 inside the filter chamber 1, then flip the flip plate 15 so that it fits against the support block 18, rotate the transmission component 17. When the transmission component 17 rotates, the fixing action of the transmission component 17 and the rotating plate 16 will drive the rotating plate 16 to rotate. When the rotating plate 16 rotates, it will be misaligned with the flip plate 15. By rotating the rotating plate 16, the effect of quickly installing or removing the fixing frame 5 can be achieved.

[0048] Referring to Figure 5, the transmission assembly 17 includes a rotating column 171, the outer wall of which is rotatably connected to the inside of the support block 18, a rotating plate 172 fixedly connected to the outer wall of the rotating column 171, and the outer wall of the rotating column 171 fixedly connected to the inside of the rotating plate 16; a groove 19 is provided inside the flip plate 15, and the flip plate 15 is slidably connected to the outer wall of the rotating plate 16 through the groove 19.

[0049] Specifically, after the flip plate 15 is attached to the support block 18, the rotating plate 172 is rotated. Through the fixing action of the rotating plate 172 and the rotating column 171, the rotating column 171 will be driven to rotate, which will further drive the rotating plate 16 to rotate. When the rotating plate 16 rotates, it will be misaligned with the flip plate 15 through the groove 19, thereby limiting the flip plate 15.

[0050] Working principle: First, connecting plate 602, connecting plate 8, and connecting plate 10 are slid into the fixed frame 5 through sliding groove 11, sliding groove 12, and sliding groove 13, thereby installing the coarse filter 601, medium filter 7, and fine filter 9 inside the fixed frame 5. When waste liquid is introduced, it will first come into contact with the coarse filter 601 to filter large particles in the waste liquid. Then, the porous ceramic material in the medium filter 7 will filter medium-sized particles in the waste liquid. Finally, the fine filter 9 will filter small particles and colloidal impurities in the waste liquid. When the coarse filter 601, medium filter 7, and fine filter 9 become clogged, high-pressure clean water can be injected into the filter chamber through the backwash pipe installed at the bottom of the filter chamber 1 to backwash the filter screens. Through the cooperation between the coarse filter 601, medium filter 7, and fine filter 9, multi-stage filtration of wastewater is achieved, thereby improving the filtration efficiency of wastewater.

[0051] First, flip the flip plate 15 so that it rotates on the outer wall of the support frame 14. When the flip plate 15 and the support block 18 are in contact with each other, rotate the second rotating plate 172. When the second rotating plate 172 rotates, it will drive the rotating column 171 to rotate inside the support block 18, and further drive the first rotating plate 16 to rotate. When the first rotating plate 16 rotates, it will be misaligned with the flip plate 15 through the groove 19, thereby achieving the effect of quickly installing and fixing the fixing frame 5.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
