Description

Technical Field

[0001] This utility model belongs to the field of freshwater cooler technology, specifically relating to a freshwater cooler with a filtration structure. Background Technology

[0002] Freshwater coolers are commonly used heat exchange devices in industry and shipbuilding, achieving efficient cooling thanks to the stable properties of freshwater. They mainly consist of cooling tube bundles, a shell, and end caps. The cooling tube bundle, as the core, is composed of multiple metal tubes with excellent heat transfer properties. Freshwater flows inside the tubes, and the medium to be cooled makes full contact with the tube walls, transferring heat to the freshwater through the tube walls to achieve cooling. The shell encloses the tube bundle, providing space for heat exchange and guiding the flow of the medium. The end caps seal both ends of the tube bundle, ensuring unobstructed freshwater circulation. Freshwater coolers have a wide range of applications. In marine propulsion systems, they cool engines and lubricating oil, ensuring navigation safety. In industrial production, they cool chemical reactors and mechanical equipment, maintaining process stability. Through the recycling of freshwater, they not only provide excellent cooling but also prevent corrosion and blockage caused by water quality issues, effectively extending equipment lifespan and improving system reliability.

[0003] Currently, existing freshwater coolers typically require freshwater to be introduced into the cooler through pipes during use, and then the freshwater is cooled through heat conduction. However, the inlet and outlet pipes of freshwater coolers often lack filtration structures. Therefore, when the freshwater enters the internal pipes of the cooler, impurities in the freshwater can easily adhere to the inner wall of the cooler pipes. Over time, this may affect the cooling effect of the freshwater and reduce the cooling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a freshwater cooler with a filtration structure, which aims to solve the problem that existing freshwater coolers typically require freshwater to be introduced into the cooler through pipes and then cooled through heat conduction. However, the inlet and outlet pipes of freshwater coolers often lack filtration structures. Therefore, when freshwater enters the internal pipes of the cooler, impurities in the freshwater can easily adhere to the inner wall of the pipes, which may affect the cooling effect and reduce cooling efficiency after long-term use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a freshwater cooler with a filtration structure, comprising a freshwater cooler body, a base fixedly connected to the bottom of the freshwater cooler body, a first inlet pipe and a first outlet pipe connected to the top of the freshwater cooler body, a connecting pipe connected to one end of the first inlet pipe and the first outlet pipe respectively, and a filter box connected to one end of the connecting pipe.

[0006] The filter box has two support frames fixedly connected to its inner wall. A filter plate is installed on the top of each of the two support frames. A sealing cover is installed on the top of the filter box. A second water inlet pipe and a second water outlet pipe are connected to the top of the sealing cover. Fixing blocks are fixedly connected to both ends of the filter plate. Limiting grooves are formed on the outer wall of the fixing blocks. A mounting base is fixedly connected to the outer wall of the filter box. A bidirectional lead screw is inserted through one end of the mounting base. Two threaded sleeves are threadedly connected to the outer wall of the bidirectional lead screw. Limiting inserts are fixedly connected to the top of the threaded sleeves.

[0007] As a preferred embodiment of the freshwater cooler with a filtration structure according to this utility model, the end of the limiting block away from the threaded sleeve is sized to match the limiting groove.

[0008] As a preferred embodiment of the freshwater cooler with a filtration structure according to this utility model, a guide rod is fixedly connected inside the mounting base, and one end of the limiting block is sleeved on the outer wall of the guide rod.

[0009] In a preferred embodiment of the present invention, a freshwater cooler with a filtration structure, the through end of the bidirectional lead screw is connected to the inner wall of the mounting base via a bearing to form a rotating connection structure.

[0010] As a preferred embodiment of the freshwater cooler with a filtration structure according to this utility model, the top of the filter box is provided with a sealing groove, and the bottom of the sealing cover is fixedly connected with a sealing protrusion.

[0011] In a preferred embodiment of the present invention, a freshwater cooler with a filtration structure, the dimensions of the sealing groove and the sealing protrusion are adapted to each other.

[0012] In a preferred embodiment of the present invention, a freshwater cooler with a filtration structure, a sealing strip is bonded to the bottom of the sealing protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By placing two filter plates on a support frame and covering them with a sealing cover, the fixing block at the end of the sealing cover will be located between the two limiting blocks. Then, by rotating the double-acting screw clockwise, the two threaded sleeves connected to the outer wall can drive the limiting blocks to move towards each other along the guide rod until one end of the limiting block is inserted into the limiting groove and fixed. Thus, the filter plates in the filter box can filter the fresh water in the inlet and outlet pipes, preventing impurities in the fresh water from adhering to the internal pipes of the fresh water cooler body, thereby improving the cooling efficiency.

[0015] With the setting of sealing groove, sealing protrusion and sealing strip, when the sealing cover covers two filter plates, the sealing protrusion at the bottom of the sealing cover will be embedded in the sealing groove, thereby playing a positioning role. After the sealing protrusion enters the sealing groove, it will also squeeze the sealing strip, thereby improving the sealing between the two. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5The present invention provides the following technical solution: a freshwater cooler with a filtration structure, including a freshwater cooler body 1, a base 2 fixedly connected to the bottom of the freshwater cooler body 1, a first water inlet pipe 3 and a first water outlet pipe 4 connected to the top of the freshwater cooler body 1, a connecting pipe 5 connected to one end of the first water inlet pipe 3 and the first water outlet pipe 4 respectively, and a filter box 6 connected to one end of the connecting pipe 5.

[0025] Two support frames 7 are fixedly connected to the inner wall of the filter box 6. A filter plate 8 is installed on the top of each of the two support frames 7. A sealing cover 9 is installed on the top of the filter box 6. A second water inlet pipe 10 and a second water outlet pipe 11 are connected to the top of the sealing cover 9. Fixing blocks 12 are fixedly connected to both ends of the filter plate 8. Limiting grooves 13 are opened on the outer wall of the fixing blocks 12. A mounting base 14 is fixedly connected to the outer wall of the filter box 6. A bidirectional screw rod 15 is inserted through one end of the mounting base 14. Two threaded sleeves 16 are threadedly connected to the outer wall of the bidirectional screw rod 15. Limiting inserts 17 are fixedly connected to the top of the threaded sleeves 16.

[0026] It should be noted that the filter box 6 has a partition inside, which prevents the flow of fresh water in and out. The top of the partition also has a sealing groove 19 and a sealing protrusion 20 embedded therein.

[0027] Preferably, the end of the limiting insert 17 away from the threaded sleeve 16 is matched with the size of the limiting groove 13, the guide rod 18 is fixedly connected inside the mounting base 14, one end of the limiting insert 17 is sleeved on the outer wall of the guide rod 18, and the through end of the bidirectional screw 15 forms a rotating connection structure with the inner wall of the mounting base 14 through a bearing.

[0028] In practical use, the two filter plates 8 are placed on a support frame 7 respectively, and then covered with a sealing cover 9. At this time, the fixing block 12 at the end of the sealing cover 9 will be located between the two limiting blocks 17. Then, by rotating the double-acting screw 15 clockwise, the two threaded sleeves 16 connected to the outer wall can drive the limiting blocks 17 to move towards each other along the guide rod 18 until one end of the limiting block 17 is inserted into the limiting groove 13 to achieve fixation. Thus, the filter plates 8 in the filter box 6 can filter the fresh water in the inlet and outlet water pipes, avoiding the situation where impurities in the fresh water adhere to the internal pipes of the fresh water cooler body 1, thereby improving the cooling efficiency.

[0029] Preferably, the top of the filter box 6 is provided with a sealing groove 19, the bottom of the sealing cover 9 is fixedly connected with a sealing protrusion 20, the dimensions between the sealing groove 19 and the sealing protrusion 20 are compatible, and a sealing strip 21 is bonded to the bottom of the sealing protrusion 20.

[0030] In practical use, with the setting of sealing groove 19, sealing protrusion 20 and sealing strip 21, when the sealing cover 9 covers the two filter plates 8, the sealing protrusion 20 at the bottom of the sealing cover 9 will be embedded in the sealing groove 19, thereby playing a positioning role. After the sealing protrusion 20 enters the sealing groove 19, it will also squeeze the sealing strip 21, thereby improving the sealing between the two.

[0031] Working principle: First, place two filter plates 8 on a support frame 7, and then cover them with a sealing cover 9. At this time, the fixing block 12 at the end of the sealing cover 9 will be located between the two limiting blocks 17. Then, by rotating the double-acting screw 15 clockwise, the two threaded sleeves 16 connected to its outer wall can drive the limiting blocks 17 to move towards each other along the guide rod 18 until one end of the limiting block 17 is inserted into the limiting groove 13 for fixation. Thus, the filter plates 8 in the filter box 6 can filter the fresh water in the inlet and outlet pipes, preventing impurities in the fresh water from adhering to the internal pipes of the fresh water cooler body 1, thereby improving the cooling efficiency. To improve efficiency, two filter plates 8 are placed on a support frame 7 and covered with a sealing cover 9. At this time, the fixing block 12 at the end of the sealing cover 9 will be located between the two limiting blocks 17. Then, by rotating the double-acting screw 15 clockwise, the two threaded sleeves 16 connected to the outer wall can drive the limiting blocks 17 to move towards each other along the guide rod 18 until one end of the limiting block 17 is inserted into the limiting groove 13 for fixation. Thus, the filter plates 8 in the filter box 6 can filter the fresh water in the inlet and outlet pipes, preventing impurities in the fresh water from adhering to the internal pipes of the fresh water cooler body 1, thereby improving cooling efficiency.
