Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and more specifically, to a waste heat recovery and heating equipment for industrial salt production. Background Technology

[0002] The industrial salt production process generates a significant amount of waste heat. Recovering and utilizing this waste heat not only prevents energy waste but also enables heating. The flue gas produced during industrial salt production also carries considerable heat. Currently, flue gas heat exchangers are commonly used to recover this heat, transferring it to a water medium to generate hot water for heating. However, over time, dust and impurities accumulate on the surface of the heat exchange tubes inside the heat exchanger. Furthermore, because the heat exchange tubes are finned tubes with densely packed spiral fins, deep cleaning requires extensive disassembly of the heat exchanger, a lengthy and tedious process that significantly impacts work efficiency. Therefore, this application provides an industrial salt production waste heat recovery and heating device to address this issue. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a waste heat recovery and heating device for industrial salt production, which improves the efficiency of finned tube assembly and disassembly by setting a fixing component to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Industrial salt production waste heat recovery and heating equipment includes a shell, an outer frame plate inserted into one side of the shell, a finned tube on one side of the outer frame plate, an inner frame plate at one end of the finned tube, a guide plate fixedly connected to the inner side of the outer frame plate, the guide plate being fixed to one side of the inner frame plate, and a fixing assembly for fixing and moving the outer frame plate. The fixing assembly is connected to the shell and the outer frame plate respectively.

[0006] In a preferred embodiment, the fixing component includes a connector fixedly connected to the top of the outer frame plate, and a support frame is rotatably connected to the outside of the connector.

[0007] In a preferred embodiment, a mounting base is fixedly connected to the top of the support frame, and a support rod is slidably connected to one end of the support frame.

[0008] In a preferred embodiment, a screw is rotatably connected to one side of the mounting base, and a transmission frame is fixedly connected to the top of the support rod.

[0009] In a preferred embodiment, the screw is threadedly connected to the transmission frame, and a handle is fixedly connected to the end of the screw away from the mounting base.

[0010] In a preferred embodiment, a fixing frame is fixedly connected to the side of the housing away from the outer frame plate.

[0011] In a preferred embodiment, the number of support rods is set to two, and the two support rods are arranged symmetrically about the horizontal center plane of the housing. One end of the support rod at the top of the housing is fixedly connected to a limiting member, and one end of the support rod at the bottom of the housing is fixedly connected to a fixed transfer frame. The fixed transfer frame is rotatably connected to a pulley.

[0012] In a preferred embodiment, the support frame is internally threaded with bolts, and the bottom of the outer frame plate is fixedly connected with a sleeve.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model sets up an outer frame plate and an inner frame plate, and places the finned tube between the outer frame plate and the inner frame plate, so that the finned tube and the shell are separated. Therefore, when disassembling and cleaning the finned tube, it is not necessary to disassemble the shell. By pulling the outer frame plate, the guide plate slides in the guide rail of the shell, so that the finned tube can slide out from the inside of the shell. The finned tube is open on all four sides, so that it can be thoroughly cleaned. This improves work efficiency by making the finned tube easy to clean.

[0015] 2. This utility model, by setting a fixed transfer frame, when it is necessary to pull the finned tube out from the inside of the shell, connects the bolts on both sides to the sleeves on both sides by rotating them, thereby fixing the fixed component located at the bottom of the shell. By rotating the screw, the transmission frame drives the support rod to descend until the pulley contacts the ground. In this way, the fixed component can support the outer frame plate, thereby enabling the disassembly of the flue gas heat exchanger located at a high position. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figure 1 As shown, the industrial salt production waste heat recovery and heating equipment of this utility model includes a shell 1, an outer frame plate 2 inserted into one side of the shell 1, a sealing gasket between the shell 1 and the outer frame plate 2 to improve the sealing between the shell 1 and the outer frame plate 2, a finned tube 3 provided on one side of the outer frame plate 2, an inner frame plate 4 provided at one end of the finned tube 3, a guide plate 5 fixedly connected to the inner side of the outer frame plate 2, the guide plate 5 fixed to one side of the inner frame plate 4, multiple guide plates 5 are provided, and multiple guide plates 5 are respectively located at the four corners of the outer frame plate 2, a guide rail is provided on the inner wall of the shell 1 so that the guide plate 5 can slide in the guide rail, and a pulley or lubricant can be provided on the side of the guide plate 5 close to the guide rail according to the actual use to reduce the friction when the guide plate 5 slides, and a fixing component, which is used to fix and move the outer frame plate 2, the fixing component is connected to the shell 1 and the outer frame plate 2 respectively, and the fixing component is set in two sets, the two sets of fixing components are symmetrical about the horizontal plane of the shell 1.

[0023] It should be noted that the side of the shell 1 closest to the outer frame plate 2 is open. The outer frame plate 2 seals the opening, and the finned tube 3 is placed between the outer frame plate 2 and the inner frame plate 4. This makes the finned tube 3 separate from the shell 1, so that the shell 1 does not need to be disassembled when the finned tube 3 is disassembled for cleaning. By pulling the outer frame plate 2, the guide plate 5 slides in the guide rail of the shell 1, so that the finned tube 3 can slide out from the inside of the shell 1. The finned tube 3 is open on all four sides, so it can be thoroughly cleaned. This improves work efficiency by making the finned tube 3 easy to clean.

[0024] Furthermore, such as Figure 3As shown, the fixing assembly includes a connector 6 fixedly connected to the top of the outer frame plate 2. A support frame 7 is rotatably connected to the outside of the connector 6. The outer contour of the support frame 7 is "H" shaped and can be connected to the other parts of the fixing assembly, thereby driving the fixing assembly to move as a whole. A mounting base 8 is fixedly connected to the top of the support frame 7. A support rod 9 is slidably connected to one end of the support frame 7. A screw 10 is rotatably connected to one side of the mounting base 8. A transmission frame 11 is fixedly connected to the top of the support rod 9. The screw 10 and the transmission frame 11 are threadedly connected. The rotation of the screw 10 can cause the transmission frame 11 to move linearly along the surface of the screw 10. A handle 12 is fixedly connected to the end of the screw 10 away from the mounting base 8. A fixing frame 13 is fixedly connected to the side of the housing 1 away from the outer frame plate 2. The fixing frame 13 is "U" shaped. Multiple fixing frames 13 can be engaged with the limiting member 14 and the fixed transfer frame 15 respectively to limit their movement. A limiting member 14 is fixedly connected to one end of the support rod 9 at the top of the housing 1.

[0025] A fixed transfer frame 15 is fixedly connected to one end of the support rod 9 at the bottom of the housing 1. The fixed transfer frame 15 is arranged in a "V" shape and protrudes from both sides of the support rod 9. A pulley 16 is rotatably connected inside the fixed transfer frame 15. A bolt 17 is threadedly connected inside the support frame 7 at the bottom of the housing 1. A sleeve 18 is fixedly connected to the bottom of the outer frame plate 2.

[0026] It should be noted that, when disassembling and cleaning the finned tube 3, the screw 10 is rotated by turning the two handles 12 respectively, causing the transmission frame 11 to drive the support rod 9 to move, causing the limiting member 14 and the fixed transfer frame 15 to move away from the fixed frame 13. At this time, the outer frame plate 2 is no longer fixed. By flipping the upper and lower fixed components until they are on the same vertical line as the outer frame plate 2, pulling any fixed component causes the finned tube 3 to slide out from the inside of the housing 1. At this time, the surface of the finned tube 3 can be cleaned. After cleaning, the installation of the housing 1 and the fixing of the outer frame plate 2 can be completed by operating the above movements in the direction, thereby realizing convenient disassembly and assembly of the finned tube 3 to improve the cleaning efficiency.

[0027] When it is necessary to pull the finned tube 3 out of the shell 1, the fixing component at the bottom of the shell 1 and the outer frame plate 2 are on the same vertical line. The fixing component at the bottom of the shell 1 is fixed by rotating the bolts 17 on both sides and connecting them with the sleeves 18 on both sides, so that it cannot move. By rotating the screw 10, the transmission frame 11 drives the support rod 9 to descend until the pulley 16 contacts the ground. In this way, the fixing component can support the outer frame plate 2. Due to the special contour setting of the fixing transfer frame 15, the stability of the fixing component supporting the outer frame plate 2 can be greatly improved. In this way, when the flue gas heat exchanger located at a high position is disassembled, the outer frame plate 2 will not be tilted or deformed by the force when the shell 1 is slid out.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
