Description

Technical Field

[0001] The invention relates to the technical field of building energy conservation, and in particular to an energy conservation and emission reduction device for buildings. Background Art

[0002] During the construction and use of buildings, in order to reduce energy consumption and pollutant emissions and achieve the goal of energy conservation and emission reduction, it is necessary to treat the exhaust gas in the building through ventilation equipment. Filters are usually installed inside the ventilation equipment to filter impurities in the air. After filtering, the air will be discharged from the outlet duct.

[0003] For example, CN115751551A discloses a ventilation device for building energy conservation and emission reduction, including a device box, one side of the device box is fixedly connected with a fresh air outlet pipe and an exhaust air inlet pipe, the other side of the device box is fixedly connected with an exhaust air outlet pipe and a fresh air inlet pipe, the fresh air outlet pipe and the fresh air inlet pipe in the device box are connected to form a fresh air channel, the exhaust air inlet pipe and the exhaust air outlet pipe are connected to form an exhaust channel, a four-sided heat exchanger is provided at the intersection of the fresh air channel and the exhaust channel, the fresh air channel and the exhaust channel circulate and exchange heat through the four-sided heat exchanger, and the fresh air channel of the device box is provided with a filtering mechanism. Both the new air and the dirty air pass through the four-sided heat exchanger, and heat exchange is performed in the four-sided heat exchanger to reduce the temperature difference between the new air entering the building and the original air inside the building, and prevent the new air outside the building from increasing the workload of the air conditioner when entering the building, thereby improving its energy conservation and emission reduction effect.

[0004] However, when a large amount of impurities remain on the filter, it is easy to cause the filter to be blocked, affecting the air filtering efficiency. At this time, the impact force on the filter will become greater. The filter is prone to damage if it is subjected to a large impact force for a long time, affecting the service life of the filter, and then affecting the air filtering effect. The filter needs to be replaced in time, which increases the frequency of filter replacement and causes a certain amount of resource waste. Summary of the invention

[0005] In view of this, the present invention provides an energy-saving and emission-reduction device for buildings. The device can automatically detect whether the air filter is blocked, and promptly issue an alarm when the air filter is blocked, so that corresponding processing can be made in time, thereby improving the practical effect of the device. The filter surface that is impacted is continuously replaced by the rotation of the air filter, thereby effectively avoiding the deformation and damage of the filter due to long-term impact force at the same position. At the same time, impurities are cleaned and collected by the dust cleaning scraper and the dust adhesion roller, thereby effectively avoiding the blockage of the air filter and ensuring the filtering efficiency of the air. At the same time, the impact force on the air filter is reduced, the probability of damage to the air filter is reduced, the service life of the air filter is improved, the filtering effect of the air is guaranteed, the replacement frequency of the air filter is reduced, and the waste of resources is reduced.

When the indoor air is discharged outdoors, the airflow will drive the second transmission wind wheel 7 and the limiting mounting rod 6 to rotate. When the limiting mounting rod 6 rotates, it will drive the air filter 5 to rotate and replace the filter surface. When the filter surface of the air filter 5 rotates into the impurity collection box 114, the impurities adhered to the outside of the air filter 5 will be scraped off by the dust cleaning scraper 115.

One end of the new dust adhesion roller 118 is inserted into the positioning mounting plate 117.

The position limiting baffle 122 can facilitate the position fixing pin 120 to rotate with the dust adhesion roller 118.

[0034] Among them, the detection structure also includes a guide limit rod 101 and an audible and visual alarm 102; there are two guide limit rods 101, and the two guide limit rods 101 are fixedly connected to the lower end surface of the positioning installation shell 1; the audible and visual alarm 102 is fixedly connected to the left side of the positioning installation shell 1.

[0035] Among them, the detection structure also includes a fixed mounting seat 105, a sliding mounting seat 107 and a first reset elastic member 110; two fixed mounting seats 105 are provided, and the two fixed mounting seats 105 are respectively fixedly connected to the middle part of the two positioning mounting rods 103; two sliding mounting seats 107 are provided, and the two sliding mounting seats 107 are respectively spline-connected to the lower part of the two positioning mounting rods 103; there are multiple first reset elastic members 110, and the two sliding mounting seats 107 are respectively elastically connected to the two positioning mounting rods 103 through multiple first reset elastic members 110.

[0036] Among them, the detection structure also includes a first connecting rod 106, a second connecting rod 108 and a limiting counterweight ball 109; four first connecting rods 106 are provided, and the four first connecting rods 106 are respectively hinged on the front and rear sides of the two fixed mounting seats 105; four second connecting rods 108 are provided, and the four second connecting rods 108 are respectively hinged on the front and rear sides of the two sliding mounting seats 107; the four first connecting rods 106 are respectively hinged to the four second connecting rods 108; four limiting counterweight balls 109 are provided, and the four limiting counterweight balls 109 are respectively fixedly connected to the upper parts of the four second connecting rods 108 through connecting ropes.

[0037] Among them, the detection structure also includes a limit mounting plate 111, a switch extrusion block 112 and a push-type switch 113; two limit mounting plates 111 are provided, and the two limit mounting plates 111 are respectively rotatably connected to the lower parts of the two sliding mounting seats 107, and the two limit mounting plates 111 are respectively slidably connected to the two guide limit rods 101; the switch extrusion block 112 is fixedly connected to the right side of the left limit mounting plate 111; the push-type switch 113 is arranged on the left side of the right limit mounting plate 111.

At this time, the switch extrusion block 112 cannot squeeze the push switch 113. If the air filter 5 is blocked, the rotation speed difference between the two positioning mounting rods 103 is large. At this time, the movement distance of the switch extrusion block 112 will be greater than the push switch 113. After the switch extrusion block 112 squeezes the push switch 113, the sound and light alarm 102 is activated to sound an alarm. At this time, the air filter 5 or the dust adhesion roller 118 can be replaced. When the device stops running, the first reset elastic member 110 will push the sliding mounting seat 107 to reset.
