Description

Technical Field

[0001] The present invention specifically relates to the technical field of ventilation and filtering equipment, in particular to a high-efficiency ventilation and filtering equipment for green buildings. Background Art

[0002] In buildings, good ventilation is key to ensuring air quality. However, outdoor air may carry pollutants such as dust, pollen, and harmful gases. Therefore, effective ventilation and filtration equipment is needed to ensure that the air introduced into the room is clean and healthy. Traditional ventilation and filtration devices generally use a simple filter structure, which has limited filtering capacity for tiny particles, harmful chemicals, etc., and cannot meet the high air quality standards required by green buildings.

[0003] In recent years, various new filter materials have emerged, such as activated carbon fibers with high-efficiency adsorption properties, nanofiber filters that can accurately intercept tiny particles, etc. However, the filtering effects of the above-mentioned filter nets are not stable under working scenarios with different air intake volumes. That is, if the gas volume is too high, due to the high gas flow rate and large inertia, it is very easy to continuously pressurize and exhaust the local part of the filter net, which makes it easy for some particulate debris to leak out; that is, if the gas volume is too low, due to the low gas flow rate and small inertia, if the number of filtering surfaces of the filter net is too large, the air resistance of the filter net will be increased, further reducing the gas flow rate and affecting the normal operation of the ventilation system. Summary of the Invention

[0004] To this end, the present invention proposes a high-efficiency ventilation and filtration device suitable for green buildings to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency ventilation and filtration device for green buildings, comprising:

[0006] The clean air treatment mechanism has an air intake hood and an exhaust hood sealed at its front and rear ports respectively;

[0010] and an air outlet pipe, which is in sealed communication with the rear port of the exhaust fan;

[0011] Wherein, filter plates are provided between the clean air treatment mechanism and the air inlet hood and the exhaust hood.

[0012] Furthermore, as a preference, the clean air treatment mechanism is composed of a fixed collar, a filter assembly, a square shell, and a cylindrical shell, wherein the cylindrical shell is arranged inside the square shell, the side walls of the front and rear ends of the cylindrical shell are fixedly sleeved with the fixed collar, and the outer side wall of each fixed collar is welded to the inner wall of the square shell;

[0013] There are multiple filter assemblies, which are evenly arranged in the cylindrical shell, and both ends of each filter assembly pass through the end wall of the cylindrical shell and then extend out.

[0014] Furthermore, preferably, the filter assembly includes:

[0015] The rear cylinder has a front end fixedly connected to the front cylinder;

[0016] A front disc body is fixedly sealed at the front port of the rear cylinder body, and an air inlet communicating with the front cylinder body is provided through the center of the front end surface of the front disc body;

[0017] A motor seat, which is fixedly installed in the rear cylinder using a plurality of connecting piles;

[0018] A rear disc body, which is fixedly mounted on the front end of the motor base;

[0019] A high-efficiency filter is provided between the front disc and the rear disc, and the front and rear ends of the high-efficiency filter are respectively connected to the front disc and the rear disc by using sealing rubber sleeves;

[0020] And a mesh support component is arranged in the high-efficiency filter and driven by a forward and reverse motor located in the motor base, and then supports and adjusts the high-efficiency filter in different forms.

[0021] Furthermore, preferably, the outer circumferential array of the high-efficiency filter has several folds to form filter angle portions, and each of the two bottom corners of the filter angle portion is connected to a fixed rod, and each of the fixed rods is fixed between the front disc and the rear disc.

[0022] Furthermore, preferably, a winding rod is provided at the center position of the inner side of the two waists of each filter angle part, and each of the winding rods is fixed between the front disc body and the rear disc body.

[0023] Furthermore, preferably, the mesh support assembly includes:

[0024] Slide rods, the number of which is the same as the number of the filter corner parts, and each of the top corners of the filter corner part is connected to a slide rod, and the two ends of the slide rod are respectively slidably connected to the slide grooves of the front disc body and the rear disc body;

[0025] A screw rod is driven by a forward and reverse motor, a threaded ring is threadedly connected to the threaded surface of the screw rod, and a circular array of two ear seats is provided on the outer wall of the threaded ring, the number of which is the same as that of the slide rod;

[0026] And the adjusting rods are the same in number as the sliding rods, one end of each adjusting rod is rotatably connected to the corresponding ear seat 2, and the other end of each adjusting rod is rotatably connected to the corresponding ear seat 1 of the sliding rod.

[0027] Furthermore, preferably, the axes of the threaded ring, the high-efficiency filter, the front disc and the rear disc are all located on the same straight line.

[0028] Furthermore, preferably, an embedded ring is fixed on the inner wall of the rear cylinder, and the embedded ring is located on the rear side of the motor seat. Steel meshes are installed at the front and rear ports of the embedded ring, and activated carbon is filled between the embedded ring and the two steel meshes.

[0029] The present invention adopts the above technology and has the following beneficial effects compared with the existing technology: a plurality of independent filter components are provided in the device of the present invention to ensure that the device of the present invention can perform continuous filtering work, and the filter component adjusts the support state of the mesh support component on the high-efficiency filter according to the high and low air intake volume. That is, when the air intake volume is high, due to the high flow rate of the gas and its accompanying particles and the large inertia, it is very easy to continuously pressurize and exhaust a part of a certain filter surface, thereby easily causing some particles and impurities to leak out. Therefore, the number of filter surfaces needs to be increased to increase the probability of intercepting particles and other impurities in the gas. Therefore, it is necessary to drive the screw to rotate forward through the forward and reverse motors, and the threaded ring and the screw rotate in conjunction with the thread. Under the directional restrictions of each adjustment rod, the threaded ring moves backward, causing each adjustment rod to tilt and make way. At the same time, the sliding rod is pulled down to fold the two waists of the filter angle around the rod, thereby folding the two filter surfaces of the filter angle into four filter surfaces, so that the filter surface of the original high-efficiency filter is doubled to ensure stable filtering treatment for high air intake volume.

[0030] When the air intake volume is low, since the flow rate of the gas and its accompanying particles is slow and the inertia is small, it is necessary to increase the area of ​​each filter surface and reduce the number of filter surfaces to reduce the overall air resistance of the high-efficiency filter. The specific operation is the same as above. The forward and reverse motors are used to indirectly drive each slide bar to move to the initial position, so that the two waists of the filter angle are straightened, thereby restoring the filter angle into two filter surfaces, reducing the formation and accumulation of air resistance, and stabilizing the filtering treatment effect of low air intake volume.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example: Please see the attached Figure 1-6 The present invention provides a technical solution: a high-efficiency ventilation and filtration device for green buildings, comprising:

[0040] The clean air treatment mechanism 5 has an air intake hood 3 and an exhaust hood 6 sealed at its front and rear ports respectively;

[0041] The exhaust fan 2 is sealed and installed at the front port of the air inlet hood 3;

[0042] An air inlet pipe 1 is sealed and connected to a front port of an exhaust fan 2;

[0043] An exhaust fan 7, which is sealed and installed at the rear port of the exhaust hood 6;

[0044] and an air outlet pipe 8, which is in sealed communication with a rear port of the exhaust fan 7;

[0045] Filter plates 4 are provided between the clean air treatment mechanism 5 and the air inlet hood 3 and the exhaust hood 6 to prevent large particles and other debris from outside or inside the building from being introduced into the clean air treatment mechanism 5, thereby affecting the clean air effect of the clean air treatment mechanism 5.

[0046] Specifically, the operating frequencies of the suction fan 2 and the exhaust fan 7 are set to be the same, so that the two can adapt to perform suction and exhaust work.

[0047] In this embodiment, the clean air treatment mechanism 5 is composed of a fixed collar 9, a filter assembly 10, a square shell 11, and a cylindrical shell 12. The cylindrical shell 12 is disposed inside the square shell 11. The side walls of the front and rear ends of the cylindrical shell 12 are fixed with fixed collars 9, and the outer wall of each fixed collar 9 is welded to the inner wall of the square shell 11.

[0048] There are multiple filter assemblies 10, which are evenly arranged in the cylindrical shell 12, and both ends of each filter assembly 10 pass through the end wall of the cylindrical shell 12 and then extend out;

[0049] It should be noted that the number of filter components 10 is set according to the actual building area to ensure stable air filtering under a certain ventilation intensity.

[0050] In this embodiment, the filter assembly 10 includes:

[0051] The rear cylinder 105 has a front end fixedly connected to the front cylinder 106;

[0052] The front disc 107 is fixedly sealed at the front end of the rear cylinder 105, and an air inlet communicating with the front cylinder 106 is provided through the center of the front end surface of the front disc 107;

[0053] The motor base 109 is fixedly mounted in the rear cylinder 105 using a plurality of connecting piles 103;

[0054] The rear disc 104 is fixedly mounted on the front end of the motor base 109;

[0055] The high-efficiency filter 108 is disposed between the front plate 107 and the rear plate 104 , and the front and rear ends of the high-efficiency filter 108 are respectively connected to the front plate 107 and the rear plate 104 using sealing rubber sleeves;

[0056] And a mesh support assembly, which is arranged in the high-efficiency filter 108 and driven by a forward and reverse motor located in the motor base 109, and then supports and adjusts the high-efficiency filter 108 in different forms.

[0057] In this embodiment, the outer circumferential array of the high-efficiency filter 108 has several folds to form filter angle portions, and each filter angle portion is connected to a fixed rod at the two bottom corners, and each fixed rod is fixed between the front disc 107 and the rear disc 104.

[0058] In this embodiment, a winding rod 117 is provided at the center position of the inner side of the two waists of each filter corner portion, and each winding rod 117 is fixed between the front disc body 107 and the rear disc body 104;

[0059] Specifically, when the waist of the filter corner portion is folded, it is folded around the winding rod 117, that is, the winding rod 117 provides support for the waist of the filter corner portion when it is deformed.

[0060] In this embodiment, the mesh support assembly includes:

[0061] The number of sliding rods 110 is the same as that of the filter corners, and each corner of the filter corner is connected to a sliding rod 110, and the two ends of the sliding rod 110 are respectively slidably connected to the sliding grooves 116 of the front disc 107 and the rear disc 104;

[0062] The screw 113 is driven by a forward and reverse motor. A threaded ring 114 is threadedly connected to the threaded surface of the screw 113. The outer wall of the threaded ring 114 has a circumferential array of ear seats 115, the same number as the sliding rod 110.

[0063] and adjusting rods 112, the number of which is the same as that of the slide rods 110, one end of each adjusting rod 112 being rotatably connected to the corresponding ear seat 2 115, and the other end of each adjusting rod 112 being rotatably connected to the corresponding ear seat 111 of the slide rod 110;

[0064] Specifically, the support state of the mesh support assembly on the high-efficiency filter is adjusted according to the high or low air intake volume (set by the operating frequency of the exhaust fan and the exhaust fan). That is, when the air intake volume is high, due to the high flow rate of the gas and its accompanying particles and the large inertia, it is very easy to continuously pressurize and exhaust a part of a certain filter surface, thereby easily causing some particles and impurities to leak out. Therefore, the number of filter surfaces needs to be increased to increase the probability of intercepting particles and other impurities in the gas. Therefore, the screw needs to be driven by the forward and reverse motor to rotate forward, and the threaded ring 114 rotates in conjunction with the screw thread. Under the directional restriction of each adjusting rod 112, the threaded ring 114 moves backward, causing each adjusting rod to tilt and make way. At the same time, the sliding rod 110 is pulled down to fold the two waists of the filter angle part around the winding rod 117, thereby folding the two filter surfaces of the filter angle part into four filter surfaces, so that the filter surface of the original high-efficiency filter is doubled, so as to ensure stable filtering treatment for high air intake volume.

[0065] When the air entrainment volume is low, since the flow rate of the gas and its accompanying particles is slow and the inertia is small, it is necessary to increase the area of ​​each filter surface and reduce the number of filter surfaces to reduce the overall air resistance of the high-efficiency filter. The specific operation is the same as above. The forward and reverse motors are used to indirectly drive each slide bar 110 to move to the initial position, so that the two waists of the filter angle part are straightened, thereby restoring the filter angle part to two filter surfaces, reducing the formation and accumulation of air resistance, and stabilizing the filtering treatment effect of low air entrainment volume.

[0066] Furthermore, it should be added that by repeatedly rotating the shape of each filter corner of the ring, particles and other debris adsorbed on the filter surface can be removed, thereby improving the filtering effect of the filter screen.

[0067] In this embodiment, the axes of the threaded ring 114 , the high-efficiency filter 108 , the front disc 107 , and the rear disc 104 are all located on the same straight line.

[0068] In this embodiment, an embedded ring 102 is fixed on the inner wall of the rear cylinder 105, and the embedded ring 102 is located on the rear side of the motor base 109. Steel meshes are installed at the front and rear ports of the embedded ring 102. Activated carbon 101 is filled between the embedded ring 102 and the two steel meshes to deodorize the gas.

[0069] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
