DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-6 This application is described in further detail.

[0020] The embodiment of the present application discloses a parallel plate and shell heat exchanger that is easy to remove scale, including a frame, a plurality of groups of heat exchange fins 4, and a mounting mechanism for mounting the heat exchange fins 4 on the frame. A flat flow channel is formed between adjacent heat exchange fins 4, and the heat exchange fins 4 can be moved on the frame to separate adjacent heat exchange fins 4. The bottoms of adjacent heat exchange fins 4 are connected by a rope body 18. A cleaning mechanism is provided on the frame, and a cleaning end of the cleaning mechanism is inserted between adjacent heat exchange fins 4 to clean the heat exchange fins 4.

[0021] In the present embodiment, by setting a rope body 18 between adjacent heat exchanger plates 4, when separating the heat exchanger plates 4, it is only necessary to move the heat exchanger plates 4 on both sides to separate all the heat exchanger plates 4, and by setting the rope body 18, the distances separating the heat exchanger plates 4 can be made equal. After the heat exchanger plates 4 are separated, the cleaning end of the cleaning mechanism can be inserted between adjacent heat exchanger plates 4 to clean the heat exchanger plates 4. When cleaning the heat exchanger plates 4, the utility model does not need to remove the heat exchanger plates 4 from the frame. Instead, the heat exchanger plates 4 are separated and then cleaned by the cleaning mechanism, which makes cleaning simpler and faster.

[0022] Furthermore, the frame includes a first fixed plate 1, a second fixed plate 2 and a movable plate 3, the first fixed plate 1 and the second fixed plate 2 are fixedly connected with sliding rods 16 on both sides of the bottom, the first fixed plate 1 and the second fixed plate 2 are connected with pressure rods 15 on the top through screws 9, the movable plate 3 and the heat exchange plate 4 are provided with grooves 14 adapted to the sliding rods 16 and the pressure rods 15 on the surface, and the pressure rods 15 and the sliding rods 16 are embedded in the corresponding grooves 14, and the movable plate 3 is connected to the second fixed plate 2 by fixing bolts 17.

[0023] In this embodiment, by providing a pressure rod 15, a sliding rod 16 and a groove body 14, the top and the bottom of the heat exchange plate 4 can be limited. In addition, by providing a movable plate 3 and a fixing bolt 17, all the heat exchange plates 4 can be tightly overlapped between the movable plate 3 and the second fixed plate 2; when the heat exchange plate 4 needs to be cleaned, the fixing bolt 17 can be unscrewed to release the restriction of the movable plate 3 on the heat exchange plate 4, so that the heat exchange plate 4 can be separated.

[0024] Furthermore, the cleaning mechanism includes a mounting seat 7 and a plurality of brush plates 8, wherein the plurality of brush plates 8 are connected to the mounting seat 7 via a rotating mechanism, and the mounting seat 7 is installed on the first fixed plate 1 and the second fixed plate 2 by setting a moving mechanism, and the mounting seat 7 can move vertically.

[0025] Furthermore, the rotating mechanism includes a rotating shaft 11 rotatably mounted on the mounting seat 7 , and the brush plates 8 are fixedly connected to the rotating shaft 11 .

[0027] In this embodiment, after the heat exchanger plates 4 are separated, the first motor 5 can be driven to drive the rotating shaft 11 and the brush plate 8 to rotate, so that the brush plate 8 changes from a vertical state to a horizontal state, and the brush plate 8 moves between the separated heat exchanger plates 4, and then the second motor 6 is driven to drive the screw rod 12 to rotate, and the ball seat 10, the mounting seat 7, the rotating shaft 11 and the brush plate 8 can move vertically, and the brush plate 8 can clean the surface of the heat exchanger plate 4 to remove dirt on the surface of the heat exchanger plate 4.

[0028] It should be noted that the ball screw is an existing transmission element, and its main function is to convert rotational motion into linear motion. It will not be elaborated here. In actual use, it is necessary to connect the second motor 6 to an external power supply and drive the second motor 6 to rotate forward and reverse to make the ball seat 10 move along the screw rod 12, and the brush plate 8 can repeatedly wash the surface of the heat exchange plate 4.
