Description

Technical Field

[0001] The utility model relates to a low-temperature waste heat utilization heat exchanger, belonging to the technical field of heat exchange devices. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction.

[0003] According to the announcement number CN213396680U, a low-temperature waste heat recovery heat exchanger is disclosed. Through the notches opened diagonally on the upper tube plate and the lower tube plate, after the upper tube plate and the lower tube plate are fitted, the assembly of the connecting block and the fixing screws is used. During the double-head screwing operation of the fixing screws, the parts of the upper tube plate and the lower tube plate can be quickly and firmly connected together. The device is detachable and has strong disassembly and usability. At the same time, the rotary shell screwed at the air inlet pipe port, in conjunction with the isolation net below it, can pre-isolate large particles of debris in the gas, reduce the burden of subsequent processing, and ensure the efficient and stable use of the low-temperature waste heat recovery heat exchanger. Although the above-mentioned device is equipped with an isolation net to pre-treat large particles of debris in the gas, when there are many large particles of debris, it will affect the air intake effect. At this time, the worker needs to separate the air inlet end from the exhaust gas pipe before removing and cleaning the isolation net, which makes the use of the device more inconvenient.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Example 1 Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0023] A low-temperature waste heat utilization heat exchanger includes a heat exchanger body 1. One side of the heat exchanger body 1 is fixedly provided with an intake end 2, and the other side of the heat exchanger body 1 is fixedly provided with an outlet end 3. The inner wall of the intake end 2 is fixedly provided with a fixing plate one 4, and a filter net one 5 is fixedly embedded through the fixing plate one 4. The top end of the intake end 2 is fixedly provided with a housing one 6, and the bottom end of the intake end 2 is fixedly provided with a housing two 7. A plug one 8 is slidably arranged on the lower inner wall of the housing one 6. The bottom end of the plug one 8 is symmetrically and fixedly provided with connecting rods one 9. The bottom ends of the connecting rods one 9 extend into the housing two 7 and are fixedly connected to a plug two 10. The bottom end of the plug two 10 is fixedly provided with a handle 11. The top end of the plug one 8 is fixedly provided with a fixing plate two 12, and a filter net two 13 is fixedly embedded through the fixing plate two 12.

[0024] Specifically, as shown in Figures 1 - 5As shown, the heat exchanger body 1 is made of corrosion-resistant non-metallic material. A housing three 14 is provided inside the air inlet end 2. A plurality of support rods 15 are symmetrically and fixedly arranged on the outer wall of the housing three 14. The other ends of the support rods 15 are fixedly connected to the inner wall of the air inlet end 2. A motor 16 is fixedly arranged inside the housing three 14. The output end of the motor 16 is fixedly connected to a rotating shaft 17. The other end of the rotating shaft 17 extends to the other side of the first filter net 5 and is fixedly connected to a scraping rod 18. The housing three 14, the rotating shaft 17, and the scraping rod 18 are all made of graphite material. The motor 16 can drive the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the scraping rod 18 to rotate. The sundries on the first filter net 5 can be scraped off by the scraping rod 18.

[0025] Specifically, as Figures 1 - 5 shown, vertical pipes 19 are fixedly arranged on the front side and the rear side of the air inlet end 2. Limit blocks 20 are slidably arranged inside the vertical pipes 19. Connecting rods two 21 are fixedly arranged at the bottom ends of the limit blocks 20. The other ends of the connecting rods two 21 extend outside the vertical pipes 19 and are fixedly connected to the handle 11. Spring sleeves 22 are slidably sleeved on the connecting rods two 21. The top ends of the spring sleeves 22 are fixedly connected to the bottom ends of the limit blocks 20. The bottom ends of the spring sleeves 22 are fixedly connected to the inner walls of the bottom ends of the vertical pipes 19. By pulling the handle 11, the handle 11 drives the second plug 10 to move downward outside the housing two 7, so that the sundries inside the housing two 7 can be discharged. At the same time, the second plug 10 drives the first plug 8 and the first fixing plate 4 to move downward through the connecting rod one 9. Thus, the top end of the housing two 7 can be blocked by the first plug 8. At the same time, the second filter net 13 on the second fixing plate 12 can filter large-particle sundries in the gas, so as to avoid the situation that large-particle sundries fall on the second plug 10 and then enter the housing one 6. When the handle 11 moves downward, at this time, the handle 11 drives the limit block 20 to move downward through the connecting rod two 21 and compresses the spring sleeve 22.

[0026] Embodiment 2 Please refer to Figure 2 and Figure 5 , the difference between this embodiment and Embodiment 1 is that the inner wall at the bottom end on the side of the air inlet end 2 close to the housing two 7 is inclined. By setting the inner wall to be inclined, it is convenient for large-particle impurities to fall into the housing two 7.

[0027] Working principle of the utility model: When in use, waste gas enters the heat exchanger body 1 through the air inlet end 2. At this time, the waste gas is filtered through the first filter screen 5, so as to pre-treat large-particle sundries in the waste gas. The motor 16 drives the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the scraping rod 18 to rotate. The sundries on the first filter screen 5 can be scraped off by the scraping rod 18, so that the sundries fall into the second housing 7. When it is necessary to clean the large-particle sundries in the second housing 7, at this time, by pulling the handle 11, the handle 11 drives the second plug 10 to move downward out of the second housing 7, so that the sundries in the second housing 7 can be discharged. At the same time, the second plug 10 drives the first plug 8 and the first fixing plate 4 to move downward through the first connecting rod 9. Thus, the top of the second housing 7 can be blocked by the first plug 8. At the same time, the second filter screen 13 on the second fixing plate 12 can filter large-particle sundries in the gas, so as to avoid the situation that large-particle sundries fall on the second plug 10 and then enter the first housing 6. When the handle 11 moves downward, at this time, the handle 11 drives the limiting block 20 to move downward through the second connecting rod 21 and compress the spring 22.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
