[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-6 The utility model provides a technical solution: a plate heat exchanger, including a mounting plate 10, a sliding rod 20, a mounting plate 201, a side plate 202, a heat exchange plate 203, a pressing block 30, a positioning block 301, a cavity 302, a spring 303, a pressing block 304, a positioning block 305, a screw rod 306, a cylinder 307, a connecting port 40, a filter screen 401, a feed port 402, a collecting box 403, a discharge valve 404, a pressing plate 405, a spring 406, a pressure sensor 407 and a shock absorbing bag 408;

[0033] The plate heat exchanger can easily replace the heat exchange plate 203, and the specific implementation method is as follows:

[0034] The mounting plate 10 is set as a vertical plane, and the surface of the mounting plate 10 is symmetrically fixedly connected with a slide bar 20; the other end of the slide bar 20 is fixedly connected with a mounting plate 201, and the surfaces of the two slide bars 20 are slidably installed with side plates 202, and a heat exchange plate 203 is slidably installed between the slide bars 20, and the surface of the mounting plate 10 is provided with a sliding mechanism, and the sliding mechanism includes: a pressure block 30 is symmetrically fixedly connected with the surface of the side plate 202, a positioning block 301 is slidably installed between the mounting plate 10 and the mounting plate 201, and a plurality of cavities 302 are embedded in the surface of the positioning block 301, the inner wall of the cavity 302 is connected with a spring 303, and the other end of the spring 303 is connected with a pressure block 2 304, a positioning block 2 305 is fixedly connected between the mounting plate 10 and the mounting plate 201, and the surface of the positioning block 2 305 A screw rod 306 is installed on the surface, and the other end of the screw rod 306 passes through the positioning block 205 and is connected to the positioning block 1 301. A cylinder 307 is installed on the surface of the mounting plate 10, and the other end of the cylinder 307 is connected to the surface of the side plate 202. The side plate 202 is slidably connected to the sliding rod 20, and the sliding rod 20 is slidably connected to the heat exchange plate 203. One side of the heat exchange plate 203 fits the surface of the side plate 202. The surfaces of the pressing block 1 30 and the pressing block 2 304 are both arranged as arc structures, and the arc end positions of the pressing block 2 304 and the pressing block 1 30 are arranged correspondingly. The pressing block 2 304 is slidably connected to the cavity 302. The positioning block 1 301 is slidably connected to the mounting plate 10 and the mounting plate 201 respectively. The interior of the positioning block 2 305 is provided with a threaded surface, and the positioning block 2 305 and the screw rod 306 are threadedly connected.

[0035] like Figure 1 , and rotate the screw rod 306 outward. At this time, the screw rod 306 moves outward along the thread inside the positioning block 2 305. At this time, the end of the screw rod 306 drives the positioning block 1 301 to move outward, so that the positioning block 1 301 moves outward between the mounting plate 10 and the mounting plate 201. At this time, the positioning block 1 301 drives the pressure block 2 304 to move outward, so that the pressure block 2 304 loses contact with the pressure block 1 30. At this time, the limit of the pressure block 2 304 on the pressure block 1 30 disappears, and the cylinder 307 is started. The cylinder 307 drives the side plate 202 to slide on the surface of the slide rod 20, so that the end of the side plate 202 loses contact with the heat exchange plate 203, and the extrusion of the heat exchange plate 203 disappears. At this time, the heat exchange plate 203 can be removed from between the two slide rods 20, and the new heat exchange plate 203 can be engaged between the two slide rods 20 to complete the replacement of the heat exchange plate 203;

[0036] When the heat exchange plate 203 is installed, the screw rod 306 is rotated in the opposite direction so that the screw rod 306 pushes the positioning block 1 301 to restore its position. At this time, the positioning block 1 301 drives the pressing block 1 30 to restore its position. The cylinder 307 is started. The cylinder 307 drives the side plate 202 to move so that the end of the side plate 202 pushes the heat exchange plate 203 to move on the surface of the slide rod 20, so that the heat exchange plates 203 fit each other. At this time, the side plate 202 drives the pressing block 1 30 to move. When the arc-shaped side of the pressing block 1 30 moves to the arc-shaped surface of the pressing block 2 304, the pressing block 1 30 can squeeze the pressing block 2 304, and the pressing block 1 30 pushes the pressing block 2 304 to move into the cavity 302. The spring 1 303 is pressed against the pressing block 304, and the pressing block 304 is pressed against the pressing block 1 30. When the pressing block 30 is moved out from the surface of the pressing block 304, the positions of the pressing block 30 and the pressing block 304 are staggered. At this time, the pressure exerted by the pressing block 204 on the pressing block 1 30 disappears, and the spring 1 303 pushes the pressing block 2 304 to rebound. At this time, the pressing block 2 304 moves to one side of the pressing block 1 30. At this time, the pressing block 2 304 is engaged with the pressing block 1 30, and the pressing block 2 304 limits the pressing block 1 30 to prevent the pressing block 1 30 from moving in the opposite direction. At this time, the pressing block 1 30 limits the side plate 202 to prevent the side plate 202 from moving in reverse, thereby completing the installation of the heat exchange plate 203.

[0037] The plate heat exchanger can filter the liquid, and the specific implementation method is as follows:

[0038] The surface of the mounting plate 10 is provided with a filtering mechanism, and the filtering mechanism includes: a plurality of connection ports 40 are provided on the surface of the mounting plate 10, and a shock absorbing bag 408 is installed on the inner wall of the connection port 40, and a filter screen 401 is installed on the surface of the shock absorbing bag 408, a feed port 402 is embedded in the inner bottom surface of the connection port 40, and a collection box 403 is fixedly connected to the surface of the connection port 40, and a discharge valve 404 is embedded in the surface of the collection box 403, a spring 2 406 is connected to the inner wall of the collection box 403, and the other end of the spring 2 406 is fixedly connected to the pressure plate 40 5. A pressure sensor 407 is installed on the inner bottom surface of the collecting box 403. Holes are arranged on the surface of the heat exchange plate 203, and the holes of the heat exchange plate 203 are arranged corresponding to the positions of the connecting port 40, and the holes of the heat exchange plate 203 are through-connected with the connecting port 40. The connecting port 40 and the filter screen 401 are slidably connected, and the positions of the filter screen 401 and the discharge port 402 are arranged correspondingly, and the discharge port 402 and the collecting box 403 are arranged correspondingly. The pressing plate 405 and the collecting box 403 are slidably connected, and the pressing plate 405 and the pressure sensor 407 are arranged correspondingly.

[0039] The pipeline for transporting the denominator liquid is connected to the connection port 40 with the filter screen 401. At this time, the denominator liquid enters the interior of the connection port 40. When the denominator liquid moves to the surface of the filter screen 401, the filter screen 401 filters the denominator liquid at the same time, so that impurities remain on the surface of the filter screen 401. The filtered material enters the interior of the heat exchange plate 203 through the connection port 40. At this time, the temperature of the heat exchange plate 203 is controlled to be adjusted from about 45°C to 40°C. The denominator liquid can be heated by the heat exchange plate 203. When the denominator liquid impacts the filter screen 401, the filter screen 401 vibrates inside the connection port 40, and the surface of the filter screen 401 falls, causing Impurities fall into the discharge port 402. At this time, the impurities fall into the internal collection box 403 through the discharge port 402. Although the liquid denominator enters the interior of the collection box 403, the collection box 403 will not generate gravity on the pressure plate 405. At this time, the impurities fall on the surface of the pressure plate 405 due to gravity. When the impurities on the surface of the pressure plate 405 increase, the pressure on the impurities increases, and the pressure plate 405 moves downward inside the pressure plate 405. When the bottom of the pressure plate 405 contacts the pressure sensor 407, the alarm is controlled by the pressure sensor 407, and at the same time, the discharge valve 404 can be controlled to open to discharge the impurities inside the collection box 403.

[0040] Working principle: When using the plate heat exchanger, a positioning block 301, a cavity 302, a spring 303, a pressure block 304, a positioning block 305 and a screw 306 are provided, so that the heat exchange plate 203 can be replaced conveniently. A spring 406, a pressure sensor 407 and a shock absorbing bag 408 are provided, so that the liquid can be filtered, thereby increasing the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
