Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, specifically to an energy-saving ventilation device for building engineering design. Background Technology

[0002] Ventilation ducts in building construction are piping systems used for air circulation, typically to ensure indoor air quality, temperature control, and humidity regulation. The design and installation of ventilation ducts are a crucial part of building construction. By expelling stale and hot air from the building while introducing fresh air, ventilation systems reduce pollutants, odors, and harmful gases in the air, thereby improving indoor air quality. Ventilation devices are generally accompanied by heat recovery systems for energy conservation.

[0003] Current building ventilation systems still have the following problems: When existing ventilation systems use heat exchange tubes to recover heat energy from exhaust gas, dust or small particulate impurities in the exhaust gas usually adhere to the inner wall of the ventilation tube and the outer wall of the heat exchange tube. During later cleaning, it is generally necessary to disassemble the ventilation tube to wipe off the dust, or use high-pressure water to wash one end of the ventilation duct. Such methods lead to complicated operation, waste of manpower, or waste of a lot of water resources and still cannot achieve a good cleaning effect. Utility Model Content

[0008] According to the above-mentioned energy-saving ventilation device for building engineering design, the top of the ventilation pipe and the mounting bracket are provided with multiple mounting holes, and the multiple heat exchange pipes pass through the center of the mounting holes.

[0009] According to the above-mentioned energy-saving ventilation device for building engineering design, the first cleaning component includes a slide block slidably connected to the front and rear end faces of the vertical section of the ventilation duct. Corrugated covers are fixedly connected to the top and bottom of the two slide blocks. A cleaning frame is fixedly connected between the two slide blocks.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 5 An energy-saving ventilation device for building engineering design includes a ventilation pipe 1, with two fixing blocks 2 fixedly connected to both the front and rear ends of the ventilation pipe 1, a filter plate 3 inserted at the top of the ventilation pipe 1, and an installation frame 4 fixedly connected inside the vertical section of the ventilation pipe 1, with a plurality of ventilation holes 5 opened on the installation frame 4.

[0025] Multiple heat exchange tubes 6 are fixedly connected between the mounting bracket 4 and the top of the ventilation duct 1. The bottom ends of the multiple heat exchange tubes 6 all penetrate the side wall of the ventilation duct 1. A first cleaning component 7 is installed inside the vertical section of the ventilation duct 1, and a second cleaning component 8 is installed on the top inner wall of the ventilation duct 1.

[0026] Multiple mounting holes are provided on the top of the ventilation duct 1 and the mounting bracket 4, and multiple heat exchange tubes 6 pass through the center of the mounting holes; this allows the multiple heat exchange tubes 6 to be stably installed inside the ventilation duct 1, thereby exchanging heat with the exhaust gas and using the exchanged heat energy for energy recovery.

[0027] The first cleaning component 7 includes slide blocks 701 slidably connected to the front and rear end faces of the vertical section of the ventilation duct 1. Corrugated covers 702 are fixedly connected to the top and bottom of both slide blocks 701. A cleaning frame 703 is fixedly connected between the two slide blocks 701. Multiple rubber sleeves 704 are fixedly connected to the bottom of the cleaning frame 703, and each rubber sleeve 704 is fitted onto the outer wall of the corresponding heat exchange tube 6. A scraper 705 is fixedly connected to the bottom of the cleaning frame 703, and the outer wall of the scraper 705 is tightly fitted against the inner wall of the ventilation duct 1. A handle 706 is fixedly connected to each of the two slide blocks 701. (The last sentence appears to be a separate, unrelated statement: "Slide down...") The movable cleaning frame 703 can drive multiple rubber sleeves 704 and scraper 705 downwards during movement, thereby scraping off dust and impurities adhering to the outer walls of multiple heat exchange tubes 6 and the inner walls of ventilation pipes 1. During use, the corrugated cover 702 moves flexibly with the slide 701, and the multiple rubber sleeves 704 fit against the heat exchange tubes 6 to prevent the cleaning frame 703 from moving downwards due to gravity, ensuring the sealing state inside the ventilation pipe 1 and preventing heat source leakage. During operation, only the two handles 706 need to be pulled down manually to complete the scraping, which is convenient and saves manpower.

[0028] The vertical section of the ventilation duct 1 has grooves on both the front and rear ends. Two slide blocks 701 are slidably connected to the inside of the grooves, and the other ends of the two sets of corrugated covers 702 are connected to the corresponding grooves. This allows the two slide blocks 701 to slide on the front and rear ends of the ventilation duct 1 and drive the corrugated covers 702 to move and seal the grooves, thereby completing the cleaning operation.

[0029] The second cleaning component 8 includes a water pipe 801 that runs through the top of the ventilation pipe 1. A nozzle 802 is fixedly connected to the bottom end of the water pipe 801. A baffle 803 is fixedly connected to the inner wall of the top of the horizontal section of the ventilation pipe 1. After the dust is scraped off, it will fall onto the top of the mounting frame 4. Water is supplied to the water pipe 801 from the outside. The water is sprayed out through the nozzle 802, thereby cleaning the fallen dust and the surface of the cleaning frame 703. The wastewater after rinsing is discharged through several ventilation holes 5. The baffle 803 can block the water sprayed from the nozzle 802 to prevent it from flowing into the room.

[0030] The nozzle 802 is located at the center of multiple heat exchange tubes 6, and the baffle 803 is set in an inclined position. The inclined baffle 803 can not only block water, but also guide the incoming exhaust gas and prevent a large amount of dust from adhering to the nozzle 802.

[0031] The working principle of this utility model is as follows:

[0032] First, the equipment is installed in the preset position using the fixing block 2. When ventilation starts, the exhaust gas enters the interior through the air inlet of the ventilation pipe 1. The filter plate 3 can filter large particles in the exhaust gas. The filtered exhaust gas is guided into the vertical section of the ventilation pipe 1 by the baffle 803. At this time, the exhaust gas exchanges heat with the fluid in the heat exchange pipe 6. The heat exchanged fluid flows out through the other end for heat recovery, and the exhaust gas is discharged through the ventilation hole 5.

[0033] When cleaning the heat exchange tubes 6 and ventilation tubes 1 is required, the handles 706 are initially positioned at the top of the slide. At this time, the two handles 706 are manually pulled downwards, causing the two slides 701 to slide inside the ventilation tube 1. The upper corrugated cover 702 is stretched, and the lower corrugated cover 702 is compressed. The cleaning frame 703 moves accordingly, causing multiple rubber rings 704 and scraper 705 to move downwards, thereby scraping off the dust and impurities adhering to the outer wall of multiple heat exchange tubes 6 and the inner wall of ventilation tubes 1. The scraped waste falls to the top of the mounting frame 4 due to gravity, or is discharged through the ventilation hole 5.

[0034] Next, water is supplied to the water pipe 801 through an external water source. The incoming water is sprayed out through the nozzle 802 to wash the top of the cleaning rack 703 and the dust that has been scraped off. The wastewater after washing is discharged through the ventilation hole 5. The baffle 803 can prevent water from flowing into the room. After cleaning, the slide 701 can be reset.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
