When the tubular heat exchanger is installed, the heat exchanger body is placed on the top of the movable plate, and the heat exchanger body with an incorrect installation position is adjusted to avoid the front and rear position of the heat exchanger body from being offset during installation, which results in the need to disassemble and adjust the base of the heat exchanger body again, which is very troublesome and time-consuming. The front and rear adjustment is convenient for workers to adjust the heat exchanger body, saves the installation time of the heat exchanger body, and reduces manpower and material costs. At the same time, it can avoid the mobile plate from moving too fast, resulting in excessive impact force, causing damage to other devices.

After the dirt on the surface of the heat exchanger is removed, the heat transfer capacity of the heat exchanger can be restored, thereby improving the overall heat exchange efficiency. At the same time, the two brush plates can be limited and locked, thereby increasing the friction between the brush on the surface of the brush plate and the heat exchanger body, thereby enhancing the cleaning effect of the dirt on the surface of the heat exchanger body.

[0016] Working principle: when the tubular heat exchanger is installed, the heat exchanger body 1 is placed on the top of the movable plate 31. When the installation position of the heat exchanger body 1 is incorrect and needs to be adjusted, the motor 35 is started, and the motor 35 starts to drive the threaded rod 36 to rotate. The rotation of the threaded rod 36 drives the cross plate 34 to move. The movement of the cross plate 34 drives the movable plate 31 to move back and forth. The movement of the movable plate 31 drives the T-shaped plate 311 to move. The movement of the movable plate 31 drives the heat exchanger body 1 to move, so as to adjust the heat exchanger body 1 with an incorrect installation position, so as to avoid the front and rear position of the heat exchanger body 1 from being offset during installation, resulting in the need to disassemble and adjust the base of the heat exchanger body 1 again, which is very troublesome and time-consuming. The front and rear adjustment is convenient for workers to adjust the heat exchanger body 1, saves the installation time of the heat exchanger body 1, reduces the manpower and material costs, and at the same time During the movement and adjustment of the movable plate 31, when the movable plate 31 moves to the edge position of the L-shaped plate 32, the movable plate 31 will squeeze the elastic telescopic plate 39, causing the elastic telescopic plate 39 to be compressed. At this time, when the movable plate 31 moves to the edge, the elastic telescopic plate 39 will contact the groove on the inner wall of the movable plate 31, causing the elastic telescopic plate 39 to reset, thereby preventing the movable plate 31 from moving too fast, resulting in excessive impact force and causing damage to other devices. When the height needs to be adjusted, the cylinder 38 starts to drive the lifting plate 33 to move, the movement of the lifting plate 33 drives the moving plate 31 to move, and the movement of the moving plate 31 drives the heat exchanger body 1 to move, thereby the heat exchanger body 1 can be further adjusted, which makes it more convenient for workers to adjust the heat exchanger body 1 during installation and increases the installation speed of the heat exchanger body 1.

[0017] When the heat exchanger body 1 is adjusted, the movement of the T-shaped plate 311 drives the reciprocating screw 41 to move, and the movement of the reciprocating screw 41 drives the transmission wheel 42 to move. The movement of the transmission wheel 42 generates friction with the L-shaped plate 32, thereby causing the transmission wheel 42 to rotate. The rotation of the transmission wheel 42 drives the reciprocating screw 41 to rotate, and the rotation of the reciprocating screw 41 drives the brush plate 43 to move, so that the surface of the heat exchanger body 1 can be cleaned to avoid the adhesion of dirt and scaling on the tube wall. Excessive adhesion and accumulation of these substances will reduce the heat transfer efficiency and affect the use effect of the device. After the dirt on the surface of the heat exchanger is removed, the heat transfer capacity of the heat exchanger can be restored, and then The overall heat exchange efficiency is improved. At the same time, when the heat exchanger body 1 is installed, the rotation of the brush plate 43 drives the fixed frame 44 to rotate, the movement of the fixed frame 44 drives the plug plate 45 to move, and the movement of the plug plate 45 drives the rotating plate 47 to move. When the rotating plate 47 moves, it will contact the fixed frame 46 so that the rotating plate 47 is squeezed into the inside of the plug plate 45. After the rotating plate 47 passes over the fixed frame 46, the rotating plate 47 is reset by the torsion spring, so that the two brush plates 43 can be limited and locked, thereby increasing the friction between the brush on the surface of the brush plate 43 and the heat exchanger body 1, thereby enhancing the cleaning effect of the dirt on the surface of the heat exchanger body 1.

When cleaning the heat exchanger, the brush plate 43 moves to drive the inclined block 51 to move. When the inclined block 51 moves, it will contact the inclined plate 55 and squeeze the inclined plate 55, so that the inclined plate 55 moves upward. The upward movement of the inclined plate 55 drives the L-shaped rod 54 to move, and the movement of the L-shaped rod 54 drives the moving rod 53 to move. The moving rod The movement of the scraper 57 drives the movement of the scraper 53, so that the inner wall of the outlet pipe 2 can be cleaned, and the raw material particles that are not completely filtered during the production process and the rust caused by the corrosion of the pipeline are prevented from being attached to the inner wall of the outlet pipe 2, resulting in the blockage of the outlet pipe 2, thereby affecting the gas outlet effect of the outlet pipe 2. The rotating plate 2 58 is movably connected to the circumferential surface of the moving rod 53. The top of the filter plate 52 contacts the top of the rotating plate 2 58, and the top of the ring plate 56 contacts the bottom of the rotating plate 2 58. The surface of the moving rod 53 is provided with a spiral groove, and the bottom of the L-shaped rod 54 contacts the top of the outlet pipe 2. At the same time, the movement of the moving rod 53 drives the rotating plate 2 58 to rotate, so that the dirt attached to the surface of the filter plate 52 can be cleaned, and the gas discharge is prevented from being smooth, thereby affecting the increase of the gas pressure in the heat exchanger, which will cause the steam to be not evenly distributed in the shell, reduce the contact area with the fluid in the pipe body, thereby reducing the heat exchange efficiency and affecting the use effect of the device.

[0019] Working principle: when cleaning the heat exchanger, the brush plate 43 moves and drives the inclined block 51 to move. When the inclined block 51 moves, it will contact the inclined plate 55 and squeeze the inclined plate 55, so that the inclined plate 55 moves upward. The upward movement of the inclined plate 55 drives the L-shaped rod 54 to move. The movement of the L-shaped rod 54 drives the moving rod 53 to move. The movement of the moving rod 53 drives the scraper 57 to move, so that the inner wall of the outlet pipe 2 can be cleaned to prevent the raw material particles that are not completely filtered during the production process and the rust caused by pipeline corrosion from adhering to the inner wall of the outlet pipe 2, causing the outlet pipe 2 to be blocked, thereby affecting the outlet effect of the outlet pipe 2. At the same time, the movement of the moving rod 53 drives the rotating plate 2 58 to rotate, so that the dirt attached to the surface of the filter plate 52 can be cleaned to avoid poor gas discharge, thereby affecting the increase of air pressure in the heat exchanger, causing the steam to be not evenly distributed in the shell, reducing the contact area with the fluid in the pipe body, thereby reducing the heat exchange efficiency and affecting the use effect of the device.
