Description

Technical Field

[0001] The invention belongs to the technical field of industrial fresh air ventilators, and in particular relates to a heat exchange core for an industrial fresh air ventilator. Background Art

[0002] The fresh air ventilator is designed and developed based on the principle that air is supplied on one side of a closed room and drawn on the other side, thus forming a "fresh air flow field" in the room. It relies on mechanical air supply and air drawing to force the formation of a fresh air flow field in the system. It is a new type of environmentally friendly appliance that keeps indoor air clean and fresh at all times. This independent indoor air replacement and purification circulation system can input natural fresh air while removing indoor polluted air. The fresh air input into the room is first filtered, sterilized, heated, oxygenated and other processes. As the use time of the fresh air ventilator increases, the heat exchange core needs to be replaced.

[0003] The Chinese patent discloses a flat plate full heat exchange core for a fresh air ventilator (CN103175293B), including a top plate, a bottom plate, and a heat exchange unit. The heat exchange unit is composed of a heat exchange membrane, a support frame, a rectifier plate, and a guide plate. The support frame is rectangular, and the heat exchange membrane is fixedly connected to the support frame to form the bottom surface of the support frame. An opening is provided at each diagonal position of the support frame, and two rectifier plates are provided between the openings. The two ends are respectively fixedly connected to the two parallel sides of the support frame where the opening is located. The guide plate is arc-shaped, one end is fixedly connected to one side of the opening, and the other end is fixedly connected to the rectifier plate; at least two heat exchange units are stacked between the top plate and the bottom plate, and the air inlet and air outlet positions of the two adjacent heat exchange units are arranged opposite to each other, and the air inlet and air outlet positions of the two alternate heat exchange units are arranged in the same manner. The flat plate full heat exchange core of the present invention has good heat and mass transfer performance, high efficiency, less resistance loss, small size, low cost, and is easy to integrate in buildings. The heat exchange cores in most industrial fresh air ventilators are exposed to the outside. Therefore, as the use time increases, dust will adhere to the outer surface or inside of the heat exchange core. If there is too much dust, it may reduce the heat exchange and ventilation effects of the fresh air ventilator, and may also reduce the working service life of the fresh air ventilator. For this purpose, a heat exchange core for an industrial fresh air ventilator is provided. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing heat exchange core is easily attached with dust and is affected by the dust, and to propose a heat exchange core for an industrial fresh air ventilator.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a heat exchange core for an industrial fresh air ventilator, comprising a filter cover, the filter cover is arranged in a cylindrical shape, a cleaning component is arranged on the side wall of the filter cover, and a disassembly component is arranged on the inner wall of the filter cover; The cleaning assembly comprises a rotating column, one end of which is rotatably connected to the side wall of the filter cover, a sprocket wheel is fixedly mounted on the outer surface of the rotating column, and a positioning ring is fixedly mounted on the outer surface of the rotating column.

[0006] As a further description of the above technical solution: A connecting rod is fixedly installed on the outer surface of the positioning ring, and a cleaning rod is fixedly installed on the side wall of the connecting rod.

[0007] As a further description of the above technical solution: A push rod is fixedly mounted on the outer surface of the cleaning rod, and the inner wall of the cleaning rod is in contact with the outer surface of the filter cover.

[0008] As a further description of the above technical solution: The disassembly and assembly assembly comprises a mounting ring and a mounting plate. The inner surface of the mounting ring is fixedly connected to the outer surface of the filter cover, and a clamping groove is fixedly installed on the side wall of the mounting ring.

[0009] As a further description of the above technical solution: A card block is fixedly mounted on the side wall of the mounting plate, and the card block is adapted to the size of the card slot.

[0010] As a further description of the above technical solution: A connecting block is fixedly installed on the inner surface of the filter cover, and a fixing ring is fixedly installed on one end of the connecting block.

[0011] As a further description of the above technical solution: The inner surface of the fixing ring is embedded in the core body, and the lower surface of the mounting plate is provided with a collecting assembly.

[0012] As a further description of the above technical solution: The collecting assembly comprises a fixing plate and a baffle plate. The upper surface of the fixing plate is fixedly connected to the outer surface of the mounting plate. A collecting frame is fixedly mounted on the side wall of the fixing plate.

[0013] As a further description of the above technical solution: A positioning pin and a torsion spring are fixedly mounted on both side walls of the baffle, and one end of the positioning pin passes through the interior of the torsion spring.

[0014] As a further description of the above technical solution: The positioning pin and one end of the torsion spring are rotatably connected to the inner walls of both sides of the collecting frame, a protrusion is fixedly installed on the upper surface of the baffle, and the push rod and the protrusion are adapted to each other.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, a cleaning component is provided. When the fan is working, the sprocket on the rotating rod drives the rotating column to rotate synchronously under the action of the toothed chain. As the rotating column rotates, the positioning ring drives the cleaning rod to rotate on the outer surface of the filter cover through the connecting rod, thereby sweeping the dust attached to the outer surface of the filter cover to the upper surface of the baffle, thereby realizing the automatic cleaning function of the industrial fresh air ventilator when working, reducing the impact of dust on the industrial fresh air ventilator as the use time increases, and further ensuring the working efficiency and ventilation quality of the industrial fresh air ventilator.

[0016] 2. In the present invention, a disassembly and assembly component is provided, and the core is inserted into the interior of the fixing ring, and the fixing ring is fixed to the interior of the filter cover by a connecting block, and then the block on the mounting plate is aligned with the slot on the mounting ring, and then the mounting plate is rotated, so that the mounting plate and the mounting ring are fixed by the block under the action of the slot, thereby sealing the core in the filter cover. During the operation of the fresh air ventilator, the filter cover will filter the dust in the air before the air passes through the core. At this time, the dust in the air will stick to the outer surface of the filter cover. The structure is simple, and it is easy to replace the heat exchange core. At the same time, the filter cover will filter the dust to prevent dust from entering the interior of the heat exchange core, thereby increasing the service life of the heat exchange core.

[0017] 3. In the present invention, by providing a collecting assembly, the cleaning rod will drive the top rod to rotate synchronously when it rotates, and the top rod will press the protrusion downward when it passes through the protrusion. At this time, the baffle will rotate under the action of the positioning pin, and then the dust on the baffle will fall into the collection frame. When the top rod rotates away, the baffle will be restored to its original position under the action of the torsion spring, thereby shielding the dust in the collection frame. When the core is replaced next time, the collection frame is cleaned and the cleaned dust is automatically collected to prevent dust from adhering to other components of the industrial fresh air ventilator, thereby improving the use effect of the industrial fresh air ventilator.

[0018] To summarize, the core is inserted into the interior of the fixing ring, the fixing ring is fixed to the interior of the filter cover through the connecting block, and then the block on the mounting plate is aligned with the slot on the mounting ring, and then the mounting plate is rotated, so that the mounting plate and the mounting ring are fixed by the block under the action of the slot, thereby sealing the core in the filter cover. The structure is simple and convenient for replacing the heat exchange core. During the operation of the fresh air ventilator, the filter cover will filter the dust in the air before the air passes through the core. At this time, the dust in the air will stick to the outer surface of the filter cover to prevent the dust from entering the heat exchange core, thereby increasing the service life of the heat exchange core. When the fan is working, the sprocket on the rotating rod drives the rotating column to rotate synchronously under the action of the tooth chain, and the other sprocket drives the rotating column to rotate synchronously. As the rotating column rotates, the positioning ring drives the cleaning rod to rotate on the outer surface of the filter cover through the connecting rod, thereby sweeping the dust attached to the outer surface of the filter cover to the upper surface of the baffle, realizing the automatic cleaning function of the industrial fresh air ventilator during operation, and reducing the impact of dust on the fresh air ventilator. The cleaning rod will drive the top rod to rotate synchronously when rotating, and the protrusion will be pressed downward when the top rod passes through the protrusion. At this time, the baffle will rotate under the action of the positioning pin, and then the dust on the baffle will fall into the collection frame. When the top rod turns away, the baffle will be restored to its original position under the action of the torsion spring, thereby blocking the dust in the collection frame. When the core is replaced next time, the collection frame will be cleaned and the cleaned dust will be automatically collected, which is convenient for unified treatment of dust.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-7 The present invention provides a technical solution: a heat exchange core for an industrial fresh air ventilator, comprising a filter cover 1, the filter cover 1 is arranged in a cylindrical shape, a cleaning component 3 is arranged on the side wall of the filter cover 1, and a disassembly component 2 is arranged on the inner wall of the filter cover 1; The cleaning assembly 3 includes a rotating column 34, one end of which is rotatably connected to the side wall of the filter cover 1, a sprocket 35 is fixedly installed on the outer surface of the rotating column 34, a positioning ring 33 is fixedly installed on the outer surface of the rotating column 34, a connecting rod 32 is fixedly installed on the outer surface of the positioning ring 33, a cleaning rod 31 is fixedly installed on the side wall of the connecting rod 32, a top rod 6 is fixedly installed on the outer surface of the cleaning rod 31, and the inner wall of the cleaning rod 31 is in contact with the outer surface of the filter cover 1.

[0029] The specific implementation example is as follows: when the fan is working, the sprocket wheel 35 on the rotating rod drives the rotating column 34 to rotate synchronously under the action of the toothed chain. As the rotating column 34 rotates, the positioning ring 33 drives the cleaning rod 31 to rotate on the outer surface of the filter cover 1 through the connecting rod 32, thereby sweeping the dust attached to the outer surface of the filter cover 1 to the upper surface of the baffle 43.

[0030] The disassembly and assembly component 2 includes a mounting ring 21 and a mounting plate 26. The inner surface of the mounting ring 21 is fixedly connected to the outer surface of the filter cover 1. A slot 22 is fixedly installed on the side wall of the mounting ring 21. A block 25 is fixedly installed on the side wall of the mounting plate 26. The block 25 is adapted in size to the slot 22. A connecting block 23 is fixedly installed on the inner surface of the filter cover 1. A fixing ring 24 is fixedly installed at one end of the connecting block 23. The inner surface of the fixing ring 24 is embedded in the core 5. The lower surface of the mounting plate 26 is provided with a collecting component 4.

[0031] The specific implementation method is as follows: insert the core body 5 into the interior of the fixing ring 24, the fixing ring 24 is fixed to the interior of the filter cover 1 through the connecting block 23, and then the block 25 on the mounting plate 26 is aligned with the slot 22 on the mounting ring 21, and then the mounting plate 26 is rotated, so that the mounting plate 26 and the mounting ring 21 are fixed by the block 25 under the action of the slot 22, thereby sealing the core body 5 in the filter cover 1. During the operation of the fresh air ventilator, the filter cover 1 will filter the dust in the air before the air passes through the core body 5, and at this time, the dust in the air will stick to the outer surface of the filter cover 1.

[0032] The collecting assembly 4 comprises a fixing plate 41 and a baffle 43, the upper surface of the fixing plate 41 is fixedly connected to the outer surface of the mounting plate 26, a collecting frame 42 is fixedly installed on the side wall of the fixing plate 41, and a positioning pin 45 and a torsion spring 46 are fixedly installed on both side walls of the baffle 43, one end of the positioning pin 45 passes through the interior of the torsion spring 46, and one end of the positioning pin 45 and the torsion spring 46 are rotatably connected to the inner walls of both sides of the collecting frame 42, a protrusion 44 is fixedly installed on the upper surface of the baffle 43, and the top rod 6 and the protrusion 44 are adapted to each other.

[0033] The specific implementation example is as follows: when the cleaning rod 31 rotates, it will drive the push rod 6 to rotate synchronously. When the push rod 6 passes through the protrusion 44, the protrusion 44 will be pressed downward. At this time, the baffle 43 will rotate under the action of the positioning pin 45, and then the dust on the baffle 43 will fall into the collection frame 42. After the push rod 6 rotates away, the baffle 43 will be restored to its original position under the action of the torsion spring 46, thereby shielding the dust in the collection frame 42. When the core 5 is replaced next time, the collection frame 42 will be cleaned.

[0034] Working principle: insert the core 5 into the interior of the fixing ring 24, fix the fixing ring 24 to the interior of the filter cover 1 through the connecting block 23, then align the block 25 on the mounting plate 26 with the slot 22 on the mounting ring 21, and then rotate the mounting plate 26, so that the mounting plate 26 and the mounting ring 21 are fixed by the block 25 under the action of the slot 22, so that the core 5 is sealed in the filter cover 1. During the operation of the fresh air exchanger, the filter cover 1 will filter the dust in the air before the air passes through the core 5. At this time, the dust in the air will stick to the outer surface of the filter cover 1. When the fan is working, the toothed sprocket 35 on the rotating rod drives the rotating column 34 under the action of the toothed chain. The baffle 43 is moved by the action of the torsion spring 46 to restore the baffle 43 to its original position, thereby shielding the dust in the collection frame 42 and cleaning the collection frame 42 until the next time the core 5 is replaced.
