Description

Technical Field

[0001] This utility model relates to the technical field of bubbling spiral plate heat exchangers, specifically a self-cleaning bubbling spiral plate heat exchanger. Background Technology

[0002] A spiral plate heat exchanger consists of two parallel metal plates rolled into two spiral channels. Hot and cold fluids exchange heat through the spiral plate walls. Spiral plate heat exchangers come in both detachable and non-detachable types. The bubbling spiral plate heat exchanger is a type of spiral plate heat exchanger. Because its spiral plates are evenly and densely covered with multiple concave points, the heat transfer contact points are dense, the heat transfer area is increased, and the volume is significantly reduced for the same heat transfer area. Its dense honeycomb units also provide strong pressure resistance. Therefore, the bubbling spiral plate heat exchanger is currently widely used.

[0003] However, existing bubbling spiral plate heat exchangers tend to accumulate dirt on their inner walls after prolonged use, affecting heat exchange efficiency. The heat exchanger is also difficult to self-clean, and the manual cleaning methods are cumbersome.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a self-cleaning bubbling spiral plate heat exchanger. Utility Model Content

The surface of the body is provided with a maintenance port, and the interior of the body is provided with heat exchange tubes. The cleaning assembly for self-cleaning of the inner wall of the body is disposed on the inner wall of the body, and the cleaning assembly includes a cleaning ring, a mounting bracket, a movable groove, rotating teeth, a control rod, and a limiting rod. The inner side of the cleaning ring is connected to the mounting bracket, and the mounting bracket has a movable groove inside. The movable groove has rotating teeth inside, and the top of the rotating teeth is connected to a control rod. The upper end of the movable groove is equipped with a limiting rod.

[0014] This utility model provides a self-cleaning bubbling spiral plate heat exchanger, which has the following beneficial effects:

[0015] 1. This utility model uses a control rod to rotate and move under the action of a top motor and a waterproof electric push rod.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2 As shown, a self-cleaning bubbling spiral plate heat exchanger includes a body 1 and a cleaning assembly 3. A maintenance port 2 is provided on the surface of the body 1 for the internal heat exchange tubes 11. The cleaning assembly 3, for self-cleaning of the inner wall of the body 1, is located on the inner wall of the body 1. The cleaning assembly 3 includes a cleaning ring 301, a mounting bracket 302, a movable groove 303, rotating teeth 304, a control rod 305, and a limiting rod 306. The mounting bracket 302 is connected to the inner side of the cleaning ring 301. The cleaning ring 301 rotates and moves inside the body 1 to perform self-cleaning, reducing manual cleaning steps. The mounting bracket 302 has a movable groove 303 inside. After engaging with the rotating tooth 304, the cleaning ring 301 moves. The rotating tooth 304 is provided inside the movable groove 303, and the top of the rotating tooth 304 is connected to the control rod 305. The control rod 305 rotates and moves under the action of the top motor and the waterproof electric push rod. The control rod 305 drives the rotating tooth 304 to rotate inside the movable groove 303. The upper end of the movable groove 303 is equipped with a limit rod 306. The rotating tooth 304 and the movable groove 303 are engaged, and the rotating tooth 304 and the control rod 305 are fixedly connected. The top of the control rod 305 is provided with an outer sleeve 4, and there are two outer sleeves 4. The upper and lower ends of the device body 1 are equipped with top flanges 5, and the front side of the device body 1 is provided with a side flange 6.

[0023] like Figure 3 As shown, a fixing bracket 7 is installed on the surface of the device body 1. The fixing bracket 7 is used to install the lead screw 8. The sealing plate 9 blocks the maintenance port 2 when the device body 1 is working. The lead screw 8 is installed on the inner side of the fixing bracket 7 via a motor. The sealing plate 9 is installed on the outer side of the lead screw 8. An adjustment component 10 is provided on the side of the sealing plate 9 to facilitate internal maintenance of the device body 1. The adjustment component 10 includes a moving block 1001 and a hydraulic rod 1002. The hydraulic rod 1002 is installed in the middle of the side of the moving block 1001. The screw 8 moves as it rotates, controlling the opening and closing of the sealing plate 9. The adjusting assembly 10 also includes a connecting block 1003 and an auxiliary rod 1004. The output end of the hydraulic rod 1002 is equipped with the connecting block 1003. The hydraulic rod 1002 controls the distance between the sealing plate 9 and the surface of the body 1 by telescoping, so that the sealing plate 9 avoids scratching the outer surface of the body 1 when it moves. The upper and lower ends of the side of the connecting block 1003 are equipped with the auxiliary rod 1004, which makes the movement of the connecting block 1003 and the sealing plate 9 more stable.

[0024] In summary, this self-cleaning bubbling spiral plate heat exchanger is first based on... Figures 1-3 The structure shown is used by connecting the top flange 5 and the side flange 6 with pipes. The heat exchange pipe 11 is connected to the top flange 5, and the heat exchange pipe 11 performs heat exchange inside the vessel body 1. After long-term use, the control rod 305 is used to rotate and move under the action of the top motor and the waterproof electric push rod. The control rod 305 drives the rotating gear 304 to rotate inside the movable groove 303. After the movable groove 303 and the rotating gear 304 mesh, the cleaning ring 301 moves. At this time, the cleaning ring 301 moves within the vessel body 1. The internal rotation and movement perform self-cleaning of the interior of the vessel body 1, reducing manual cleaning steps. When maintaining the interior of the vessel body 1, the hydraulic rod 1002 is first controlled to extend and retract to control the distance between the sealing plate 9 and the surface of the vessel body 1, so that the sealing plate 9 avoids scratching the outer surface of the vessel body 1 when moving. When moving, the auxiliary rod 1004 makes the connecting block 1003 and the sealing plate 9 more stable when moving. Then, the belt is opened to make the lead screw 8 rotate, so that the sealing plate 9 is removed from the maintenance port 2 on the vessel body 1 to expose it, making it easier for personnel to maintain.
