This solution solves the problem that existing equipment is fixed with bolts, which requires screwing multiple bolts during disassembly, resulting in low disassembly and installation efficiency.
[0021] In this specific embodiment, the heat exchanger is installed on the filter box 101. The heat exchanger is the same as the one described in the existing patent technology CN222418742U, a finned tube heat exchanger. The heat exchanger is installed on the filter box 101 and heat exchange is achieved through the heat exchanger. This solution makes it easier to replace the filter plate 104, thereby improving work efficiency.

The sealing component seals the filter box 101. The mounting rail 102 is bolted to the inside of the filter box 101. The sliding frame 103 is slidably mounted on the mounting rail 102, and the mounting rail 102 restricts the movement trajectory of the sliding frame 103, so that the sliding frame 103 is vertically mounted in the filter box 101. The filter plate 104 is a filter plate described in the prior art patent CN222418742U, a finned tube heat exchanger. The filter plate 104 is fixedly mounted on the sliding frame 103, and the sliding frame 103 fixes the filter plate 104 in the filter box 101, so that the filter plate 104 can perform filtration. The limiting block 105 is mounted on the filter box 101 via the mounting member. The mounting member supports the limiting block 105, allowing it to abut against the sliding frame 103. The sliding frame 103 has a locking hole that mates with the limiting block 105, thus allowing the limiting block 105 to fix the sliding frame 103 in the filter box 101. The sealing member is mounted on the sliding frame 103, sealing the gap between the sliding frame 103 and the filter box 101, thereby ensuring efficient heat exchange and enabling more convenient replacement of the filter plate 104, thus improving work efficiency.
[0023] Secondly, the mounting cylinder 106 is fixedly connected to the filter box 101 and located on the side of the filter box 101 away from the heat exchanger, and is connected to the limiting block 105; the sliding block 107 is slidably connected to the mounting cylinder 106 and located on the side of the mounting cylinder 106 close to the filter box 101, and is connected to the limiting block 105; the driving element is mounted on the limiting block 105, and the driving element drives the sliding block 107 to move; the mounting cylinder 106 is mounted on the outside of the filter box 101 by bolts, and the limiting block 105 passes through the mounting cylinder 106. The limiting block 105 can slide in the mounting cylinder 106. The sliding block 107 is slidably installed in the mounting cylinder 106, and the limiting block 105 is fixedly installed on the sliding block 107. The sliding block 107 can drive the limiting block 105 to move, so that the limiting block 105 engages with the sliding frame 103. The driving element is installed on the limiting block 105, and the driving element drives the sliding block 107 to move, so that the sliding block 107 drives the limiting block 105 to move, and the limiting block 105 fixes the sliding frame 103.
[0024] Meanwhile, the spring 108 is sleeved on the outside of the limiting block 105, and the two ends of the spring 108 abut against the sliding block 107 and the mounting cylinder 106 respectively; the pull block 109 is fixedly connected to the limiting block 105 and is located on the side of the limiting block 105 away from the sliding block 107. The spring 108 is sleeved on the outside of the limiting block 105, and the two ends of the spring 108 abut against the sliding block 107 and the mounting cylinder 106 respectively. The spring force of the spring 108 drives the limiting block 105 to move, so that the limiting block 105 engages with the sliding frame 103 to fix the sliding frame 103. The pull block 109 is fixedly installed on the limiting block 105 by bolts. By pulling the limiting block 105 with the pull block 109, the limiting block 105 is moved away from the sliding frame 103, so that the sliding frame 103 can slide out of the filter box 101.
[0025] In addition, the sealing cover 110 is fixedly connected to the sliding frame 103 and is located on the side of the sliding frame 103 away from the mounting rail 102; the sealing strip 111 is fixedly connected to the sealing cover 110 and is located on the side of the sealing cover 110 close to the filter box 101, and abuts against the filter box 101. The sealing cover 110 is fixedly installed on the sliding frame 103 by bolts, and the sealing cover 110 covers the gaps on the filter box 101. The sealing strip 111 is fixedly installed on the sealing cover 110, and the sealing strip 111 improves the sealing performance between the sealing cover 110 and the filter box 101, thereby ensuring the efficiency of heat exchange.
[0026] Finally, the sealing groove 112 is located on the side of the filter box 101 near the sealing strip 111 and cooperates with the sealing groove 112. The sealing groove 112 is set on the side of the filter box 101 near the sealing strip 111, so that the sealing strip 111 can be inserted into the filter box 101, thereby improving the sealing performance between the sealing cover 110 and the filter box 101.
[0027] Using a finned tube heat exchanger according to this embodiment, when the filter plate 104 needs to be cleaned, the pull block 109 pulls the limiting block 105, allowing the sliding frame 103 to move and pull the filter plate 104 out of the filter box 101, thus completing the cleaning of the filter plate 104. After cleaning, the sliding frame 103 is inserted into the mounting rail 102, causing the sealing strip 111 to engage with the sealing groove 112. At this time, the pull block 109 is released, and the spring 108 drives the sliding block 107 to move, causing the limiting block 105 to engage with the sliding frame 103, thereby fixing the sliding frame 103. This achieves a more convenient replacement of the filter plate 104, thereby improving work efficiency.
