Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, and particularly relates to a plate heat exchanger for seawater aquaculture. Background Technique

[0002] Plate heat exchangers are widely used in daily production and life. Briefly, the principle of its action is that two kinds of hot and cold media complete interval heat transfer through the corrugated channels regularly arranged on the heat exchange plates to achieve the purpose of heat exchange. It can be used to adjust the seawater temperature to ensure that the aquaculture water body is within the most suitable temperature range.

[0003] Due to excessive impurities in seawater, the inside of the plate heat exchanger needs to be regularly cleaned. The plate heat exchanger adopts a detachable method, and the screws can be loosened to clean each piece, so as to reach the use state before leaving the factory. In addition, the interface position can be adjusted according to the existing pipeline layout of users, greatly saving the installation cost of users. The application of plate heat exchangers in seawater aquaculture not only improves the heat transfer efficiency and saves floor space, but also becomes an ideal heat exchange device in the seawater aquaculture industry due to its flexible installation and operation.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figure 1 shown, a plate - type heat exchanger for seawater aquaculture includes a fixed clamping plate 1, a movable clamping plate 3, a heat exchange plate 2 and an upright column 5. The heat exchange plate 2 is clamped and fixed by the fixed clamping plate 1 and the movable clamping plate 3. One side of the movable clamping plate 3 is provided with a pressing member 4. As Figure 3 shown, the pressing member 4 includes two parallel pressing rods 402, and the two pressing rods 402 are connected by a push rod 403. As Figure 5 shown, a nut sleeve 501 is arranged inside the upright column 5, and a pressing screw rod 6 for pushing the push rod 403 is fitted inside the nut sleeve 501. A pressing column 401 for pressing the movable clamping plate 3 is arranged on the side wall of the pressing rod 402. By rotating the pressing screw rod 6, the pressing screw rod 6 presses and fixes the movable clamping plate 3 through the pressing member 4.

[0027] The number of pressing columns 401 on each pressing rod 402 is at least four, and the end of the movable clamping plate 3 is pressed from top to bottom. The number of push rods 403 is at least three. In this application, there are three push rods 403, corresponding to the upper, middle and lower positions of the movable clamping plate 3 respectively, and each push rod 403 corresponds to a pressing screw rod 6.

[0028] In order to ensure accurate position and improve the installation speed during each installation, as Figure 2 shown, a positioning block 301 is arranged on the side wall of the movable clamping plate 3. As Figure 4 shown, a second positioning groove 405 for cooperating with the positioning block 301 is arranged at the end of the pressing column 401, which can quickly position the pressing member 4.

[0029] In order to increase the pressing force, the push rod 403 is of an arc structure. The two ends of the push rod 403 are connected to the pressure rod 402, and the middle part of the push rod 403 is engaged with the pressing screw 6.

[0030] A first positioning groove 404 is provided in the middle part of the push rod 403, and a top block 601 engaged with the first positioning groove 404 is provided at the end of the pressing screw 6. The two sides of the pressing member 4 are positioned through the first positioning groove 404 and the second positioning groove 405, and at the same time, the reliability during use can be improved, and the pressing member 4 is prevented from sliding.

[0031] During the use process, in order to prevent the pressing screw 6 from loosening, as Figure 5 shown, two guiding screws 503 are connected to the side wall of the column 5. A slidable anti - detachment rod 7 is sleeved outside the guiding screw 503. A limiting nut 505 for pressing the anti - detachment rod 7 is provided on the guiding screw 503. After the pressing screw 6 is pressed, the positioning nut is rotated to make the anti - detachment rod 7 abut against the head of the pressing screw 6, so as to limit and fix the pressing screw 6 and prevent the pressing screw 6 from loosening.

[0032] A limiting block 504 is provided at the end of the guiding screw 503. A spring 502 is sleeved outside the guiding screw 503. The spring 502 connects the column 5 and the anti - detachment rod 7. During disassembly, the positioning nut is rotated, and under the action of the spring 502, the anti - detachment rod 7 automatically pops open, which is convenient to use. At the same time, during the pressing process, the spring 502 can prevent the limiting nut 505 from loosening.

[0033] During installation, the pressing member 4 is matched with the movable clamping plate 3, so that the second positioning groove 405 is matched with the positioning block 301. The pressing screw 6 is rotated to make the top block 601 located in the first positioning groove 404, and the pressing member 4 is tightly pressed by rotating the pressing screw 6. Through the pressing member 4, the movable clamping plate 3 and the fixed clamping plate 1 clamp and fix the heat exchange plate 2. After the pressing screw 6 is pressed, the limiting nut 505 is rotated to make the anti - detachment rod 7 press against the head of the pressing screw 6; during disassembly, the pressing nut is loosened, the spring 502 pops the anti - detachment rod 7 open, the pressing screw 6 is loosened, and the pressing member 4 is removed, then the movable clamping plate 3 and the heat exchange plate 2 can be removed. The disassembly and assembly are simple and fast.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model.
