Description

Technical Field

[0001] The utility model relates to an air-to-air heat exchange plate, belonging to the technical field of heat exchange plates. Background Art

[0002] The air-to-air plate heat exchanger is a new type of energy-saving and environmentally friendly equipment, which is composed of a large number of stamped stainless steel sheets. The plates are fully welded and sealed. Flue gas and air flow in the plates for heat exchange. The air-to-air plate heat exchanger is suitable for air preheating and waste heat recovery in the steel, papermaking, chemical, electric power, battery and other industries. It is an exchanger for gas heat exchange and can be used as a heat exchanger for heating combustion air in flue gas with a temperature of up to 760 degrees. Its function is to recover heat and reduce consumption. It has a wide range of applications. In places where high-temperature flue gas is discharged, this air preheater can be used to recover heat energy, save fuel and achieve environmental protection. The air-to-air heat exchange plate is the main heat exchange structure in the air-to-air plate heat exchanger.

[0003] For example, the patent publication number CN202221987827.2 is a low-resistance self-supporting heat exchange plate for an air-to-air heat exchanger, including a heat exchange plate pair, the heat exchange plate pair including an upper plate and a lower plate, the upper plate and the lower plate are both provided with multiple rows of bulges, each row of bulges is alternately arranged with convex bulges and concave bulges, the concave bulges of the upper plate and the lower plate support each other to form a heat exchange flow channel 1, the convex bulges of adjacent heat exchange plate pairs support each other to form a heat exchange flow channel 2, and the upper plate and the lower plate are provided with concave ribs;

[0004] Since the above-mentioned heat exchange plate is installed and positioned in the heat exchanger through an external structure, and the heat exchange plate is fixedly connected by two heat exchange plates, it is inconvenient to subsequently disassemble and replace a single damaged heat exchange plate. In addition, since there are many heat exchange plates in the heat exchanger, if one of them falls accidentally, it will hit and damage other heat exchange plates, which brings certain adverse effects to actual use, so improvement is needed.

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.

[0025] Example 1 Please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] An air-to-air heat exchange plate comprises an air-to-air heat exchange plate 1, the surface of the air-to-air heat exchange plate 1 is in contact with an air-to-air heat exchange plate 2, the side surfaces of the air-to-air heat exchange plate 1 and the side surfaces of the air-to-air heat exchange plate 2 are fixedly connected with side fixing plates 3, the side surfaces of the side fixing plates 3 are provided with external positioning screw grooves 4, the interior of the side fixing plates 3 is provided with connecting grooves 5, the inner wall of the connecting grooves 5 is fixedly connected with a magnetic abutment plate 1 6, the surface of the side fixing plate 3 near the middle thereof is fixedly connected with an extension rod 7, the surface of the extension rod 7 is fixedly connected with a magnetic abutment plate 2 8, and the surface of the magnetic abutment plate 2 8 is magnetically abutted with the surface of the magnetic abutment plate 1 6.

[0027] Specifically, Figure 1-Figure 5 As shown, the overall shape of the air heat exchange plate 1 and the air heat exchange plate 2 are both inner groove plates, and the inner groove plates are fixedly connected with an inner concave heat exchange pad 9 and an outer convex heat exchange pad 10, and the inner concave heat exchange pad 9 and the outer convex heat exchange pad 10 are connected to the air heat exchange plate 1 and the air heat exchange plate 2 in a staggered shape. The air heat exchange plate 1 and the air heat exchange plate 2 are both connected with the inner concave heat exchange pad 9 and the outer convex heat exchange pad 10, so that the inner concave heat exchange pad 9 and the outer convex heat exchange pad 10 on the air heat exchange plate 1 are staggered and abutted with the inner concave heat exchange pad 9 and the outer convex heat exchange pad 10 on the air heat exchange plate 2, so that the air can be quickly guided and transferred. Because the inner concave heat exchange pad 9 and the outer convex heat exchange pad 10 are arranged alternately and cyclically at equal distances, a fast and smooth heat exchange flow channel can be formed and the risk of leakage can be reduced, so that the hot air and the cold air can be exchanged without contacting each other in the subsequent operation.

[0028] Specifically, Figure 1-Figure 5 As shown, a sealing ring gasket 15 is fixedly connected to the surface of the side fixing plate 3, and the surface of the sealing ring gasket 15 on the front side of the side fixing plate 3 and the surface of the sealing ring gasket 15 on the rear side of the side fixing plate 3 are sealed and clamped, because the two sealing ring gaskets 15 can play a sealing abutment effect at the side fixing plate 3.

[0029] Furthermore, an anti-slip positioning plate 16 is fixedly connected to the surface near the middle of the connecting groove 5, and an anti-slip positioning sleeve 17 is fixedly connected to one end of the extension rod 7. The inner wall of the anti-slip positioning sleeve 17 and the surface of the anti-slip positioning plate 16 are snap-fitted and adapted. Through the arrangement of the anti-slip positioning plate 16 and the anti-slip positioning sleeve 17, the installation connection points of the two side fixing plates 3 can be quickly found, and the two side fixing plates 3 can be fixed to each other.

[0030] Example 2 Please refer to Figure 1-Figure 5 The difference between this embodiment and the embodiment 1 is that: the surface of the side plate 3 is fixedly connected with a magnetic card plate 11, and the surface of the magnetic card plate 11 is clamped with an outer enclosure plate 12. A shock absorber 13 is fixedly installed on the surface of the outer enclosure plate 12, and one end of the shock absorber 13 is fixedly connected with an anti-collision pad 14, and the surface of the anti-collision pad 14 is coated with a wear-resistant coating. The outer enclosure plate 12 can be freely replaced through the magnetic card plate 11, which can play a role in protecting the periphery of the gas heat exchange plate 1 and the gas heat exchange plate 2, and the shock absorber 13 and the anti-collision pad 14 are added thereon for external protection to prevent the gas heat exchange plate 1 and the gas heat exchange plate 2 from accidentally falling and hitting and damaging other gas-to-gas heat exchange plates.

[0031] Working principle of the utility model: when in use, the staff can install it in the interior of the heat exchanger through the external positioning screw groove 4 on the side of the side fixing plate 3. Before the entire air-to-air heat exchange plate is installed, the air-to-air heat exchange plate 1 1 and the air-to-air heat exchange plate 2 2 can be assembled and combined, and the extension rod 7 in the side fixing plate 3 can be extended into the inside of another connecting groove 5. Through the setting of the anti-slip positioning plate 16 and the anti-slip positioning sleeve 17, the installation connection points of the two side fixing plates 3 can be quickly found. After the two side fixing plates 3 are fixed to each other, the extension rod 7 is magnetically locked in the connecting groove 5 under the action of the magnetic attraction plate 1 6 and the magnetic attraction plate 2 8, and the air-to-air heat exchange plate 1 1 and the air-to-air heat exchange plate 2 2 can be connected. Because the air-to-air heat exchange plate 1 and the air-to-air heat exchange plate 2 are both connected with the inner concave heat exchange pad 9 and the outer convex heat exchange pad 10, the inner concave heat exchange pad 9 on the air-to-air heat exchange plate 1 and the outer convex heat exchange pad 10 are formed. The heat exchange pad 10 is staggered and abutted with the concave heat exchange pad 9 and the convex heat exchange pad 10 on the air-to-air heat exchange plate 2, so that the air can be quickly guided and transferred. Because the concave heat exchange pad 9 and the convex heat exchange pad 10 are arranged alternately and cyclically at equal distances, a fast and smooth heat exchange flow channel can be formed and the risk of leakage can be reduced, so that the hot air and cold air in the subsequent operation can be exchanged without contacting each other. Because there are many air-to-air heat exchange plates in the heat exchanger, shock absorbers 13 and anti-collision pads 14 are added to the air-to-air heat exchange plates 1 and 2 for external protection, and the outer protective plate 12 can be freely replaced by the magnetic card plate 11, which can play a role in protecting the periphery of the air-to-air heat exchange plates 1 and 2, and avoid the air-to-air heat exchange plates 1 and 2 from accidentally falling and colliding and damaging other air-to-air heat exchange plates, thereby ensuring the rapid disassembly and installation of the air-to-air heat exchange plates and the protection effect.

[0032] 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.
