Description

Technical Field

[0001] This invention relates to the field of industrial plant structure technology, and in particular to a plant with ventilation and filtration functions and its usage method. Background Technology

[0002] With the large-scale development of industry, environmental protection and operational requirements have increased in recent years, leading to higher demands for ventilation and purification in factory buildings. Traditional factory structures are no longer adequate to meet these new needs. Existing factory ventilation and filtration systems generally consist of ordinary static filters paired with fans, which intercept impurities as air passes through the filters.

[0003] Traditional ventilation and filtration systems have obvious drawbacks. Static filters are prone to clogging, requiring shutdown and cleaning every two or three days, which delays production and is time-consuming and labor-intensive. They also lack an integrated linkage structure for filtration and self-cleaning, making it impossible to guarantee uninterrupted operation of the ventilation and filtration system. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a factory building with ventilation and filtration functions and a method of use, aiming to improve the problem that traditional ventilation and filtration systems lack an integrated linkage structure of filtration and self-cleaning, and cannot guarantee the uninterrupted operation of the ventilation and filtration system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a factory building with ventilation and filtration functions, including a base, with plug-in components fixedly connected to the four corners of the lower surface of the base, and pile foundations detachably connected to the outer side of the plug-in components by bolts; an installation frame detachably connected to the upper surface of the plug-in components by bolts; a front wall panel, a right wall panel, a left wall panel, a rear wall panel, and a roof are detachably connected to the front, right, left, rear, and top sides of the installation frame by bolts, respectively; a ventilation box is embedded in the left wall panel, and a fan for driving the airflow in the workshop is installed in the ventilation box; a passageway for air to pass through is provided in the ventilation box; a filter assembly is provided in the ventilation box, and the filter assembly includes a mounting frame, a first transmission roller, a second transmission roller, an adhesive cloth, a gear transmission mechanism, a roller brush, and a motor; the output shaft of the motor is fixedly connected to the second transmission roller; the adhesive cloth is wound around the first and second transmission rollers and circulates; the roller brush is linked to the first transmission roller through the gear transmission mechanism, and the bristles of the roller brush are in contact with the outer wall of the adhesive cloth.

[0006] Preferably, the mounting bracket is fixed to the lower surface of the ventilation box, a first transmission roller is rotatably connected between the mounting brackets, a second transmission roller is rotatably connected inside the ventilation box and is arranged vertically corresponding to the first transmission roller, and the motor is fixed to the rear side of the ventilation box.

[0007] Preferably, the gear transmission mechanism includes a first gear, a bearing seat, a second gear, and a shaft; the first gear is fixed to both ends of the first transmission roller, the bearing seat is fixed to the bottom of the mounting frame, the second gear is rotatably mounted on the bearing seat and meshes with the first gear, the shaft is fixedly connected between the two second gears, and the roller brush is coaxially fixed on the shaft.

[0008] Preferably, the front wall panel is rotatably connected to a door panel via a hinge, and a ventilation mesh is embedded above the right wall panel.

[0009] Preferably, a water collection trough is integrally formed on the upper surface of the roof, and at least one drain connector is integrally formed on the rear side of the roof; a water storage cavity is fixed on the rear side of the rear wall panel, and an inlet connector corresponding to the drain connector is integrally formed on the top of the water storage cavity, and a drain pipe is detachably connected between the inlet connector and the drain connector.

[0010] Preferably, a cover plate is detachably connected to the rear side of the water storage chamber by bolts, a filter screen is fixed inside the water storage chamber, and an extraction pipe with its top extending to the outside is provided inside the water storage chamber.

[0011] A method for using a factory building with ventilation and filtration functions includes the following steps:

[0012] S1. Ventilation and filtration operation: Start the fan in the ventilation box to drive the air circulation in the workshop. At the same time, start the motor to drive the transmission roller two to rotate, driving the adhesive cloth belt to circulate. When the air containing impurities in the workshop passes through the channel, the lint, dust and impurities in the air are adsorbed and filtered by the adhesive cloth belt.

[0013] S2. Self-cleaning operation: Synchronously driven roller brushes clean the adhered fabric belt in real time to prevent filter clogging;

[0014] S3. Rainwater harvesting operation: When it rains, the rainwater collection tank on the roof collects rainwater from the roof. The rainwater flows into the water storage chamber through the drain connector and drain pipe. After being filtered by the filter screen to remove leaves, dust and impurities, it is stored in the water storage chamber.

[0015] S4. Water Reuse Operation: When water is needed, filtered clean rainwater is extracted through the extraction pipe in the water storage chamber for use in cleaning the factory floor or irrigating the surrounding greenery.

[0016] Preferably, in S2, while the second transmission roller drives the adhesive fabric belt, it simultaneously drives the first transmission roller to rotate. The first transmission roller drives the first gear at both ends to rotate, and the meshing second gear drives the roller brush to rotate synchronously. The roller brush removes lint and impurities from the adhesive fabric belt in real time.

[0017] The present invention has the following beneficial effects:

[0018] 1. The ventilation box integrated component of the present invention can achieve simultaneous operation of filtration and self-cleaning. First, the impurity-laden air in the workshop is drawn into the channel by the exhaust fan, allowing the air to pass through the circulating adhesive cloth belt, continuously adsorbing lint and dust impurities in the air, and always maintaining the cleanliness of the workshop air. Then, the cleaning action is completed synchronously by the power of the same motor. While the motor drives the transmission roller to rotate, it drives the adhesive cloth belt to circulate, and the transmission of the cloth belt synchronously drives the gear set to rotate, thereby driving the brush to synchronously complete the real-time cleaning of the filter element. This solves the problem that traditional ventilation filtration devices can only statically intercept impurities and cannot avoid the clogging of the filter port. No matter how much dust and impurities are generated in the workshop, the ventilation filtration system can be guaranteed to operate continuously without the need for shutdown for cleaning.

[0019] 2. The integrated water storage component of the roof and rear wall panel of this invention enables on-site collection and reuse of rainwater. The integrated water collection trough on the roof can quickly collect falling rainwater and guide it to the drain connector. The rainwater is then directly introduced into the water storage chamber of the rear wall panel through the connected drain pipe. The filter screen in the water storage chamber simultaneously filters impurities from the rainwater, allowing the filtered clean rainwater to be directly stored inside the wall panel. This solves the problem of resource waste caused by the direct discharge of rainwater from traditional industrial plants. The collected rainwater can be directly used for plant cleaning and greening irrigation, significantly reducing the plant's operating water costs. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, refer to Figures 1-8A factory building with ventilation and filtration functions includes a base 1. Connectors 2 are fixedly connected to the four corners of the lower surface of the base 1. Pile foundations 3 are detachably connected to the outer sides of the connectors 2 via bolts, providing stable bottom support for the entire factory building. An installation frame 4 is detachably connected to the upper surface of the connectors 2 via bolts. The installation frame 4 is the main load-bearing skeleton of the entire factory building. Front wall panels 5, right wall panels 6, left wall panels 7, rear wall panels 32, and a roof 8 are detachably connected to its front, right, left, rear, and top sides via bolts, respectively. All components can be prefabricated in the factory and quickly assembled on-site. A ventilation box 9 is embedded inside the left wall panel 7; this is an integrated functional component that combines ventilation and purification functions. The ventilation box 9 is equipped with a fan 10 to drive the airflow in the workshop, which can quickly circulate the air in the workshop. The ventilation box 9 is equipped with a filter assembly, which includes a mounting frame 12, a first transmission roller 13, a second transmission roller 14, an adhesive tape 15, a gear transmission mechanism, a roller brush 31, and a motor 26. The output shaft of the motor 26 is fixedly connected to the second transmission roller 14. The adhesive tape 15 is wound around the first transmission roller 13 and the second transmission roller 14 and is circulated. The roller brush 31 is linked to the first transmission roller 13 through the gear transmission mechanism. The bristles of the roller brush 31 are in contact with the outer wall of the adhesive tape 15. The ventilation box 9 is provided with a channel 11 for air to pass through, ensuring that all air containing impurities is filtered and there is no air leakage. A mounting bracket 12 is fixed to the lower surface of the ventilation box 9. This bracket provides a stable support for the transmission components, ensuring that the position of the transmission components remains unchanged. A transmission roller 13 is rotatably connected between the mounting brackets 12. A transmission roller 14, corresponding to the transmission roller 13, is rotatably connected inside the ventilation box 9. The two transmission rollers are arranged vertically to achieve the cyclic transmission of the adhesive tape 15, ensuring that filtration and cleaning are performed synchronously. A motor 26 is fixed to the rear of the ventilation box 9. This is the common power source for the entire filtration and cleaning assembly. It can drive both functions simultaneously without the need for an additional independent cleaning power source. The output shaft of the motor 26 is fixedly connected to the transmission roller 14, which drives the transmission roller 14 to rotate, thereby driving the adhesive tape 15 to circulate and providing synchronous power support for filtration and cleaning.The gear transmission mechanism includes gear 27, bearing 28, gear 29, and shaft 30. Gear 27 is fixed at both ends of the transmission roller 13, which can output cleaning power synchronously with the rotation of the transmission roller. The bottom of the mounting frame 12 is provided with bearing 28, which provides stable support for the rotation of the cleaning component. Gear 29, which meshes with gear 27, is provided on bearing 28, which can synchronously transmit the power of the transmission roller to the cleaning component. The two gears 29 are connected to the roller brush 31 through shaft 30, thereby realizing the synchronous operation of the cleaning component and the filter component. The bottom of the ventilation box 9 is provided with a dust collection hopper. The lint and dust brushed off by the roller brush 31 will automatically slide down into the dust collection hopper under the action of gravity and be stored in a concentrated manner to prevent the dust from being dispersed into the workshop air again and to ensure the cleanliness of the workshop. When the lint and dust in the dust collection hopper reach a certain amount, the operator can clean it periodically.

[0032] Example 2, refer to Figures 1-8 Based on Embodiment 1, the front wall panel 5 is hinged to a door panel 16, facilitating staff entry and exit from the workshop. The wall panel can also be quickly opened for internal component inspection when needed. A ventilation mesh 17 is embedded above the right wall panel 6, enabling air circulation within the workshop while preventing external impurities from entering. A water collection trough 18 is integrally formed on the upper surface of the roof 8, quickly collecting rainwater and guiding it to a designated drainage location. At least one drain connector 19 is integrally formed on the rear side of the roof 8. A water storage chamber 20 is fixed to the rear side of the rear wall panel 32; this integrated water storage component does not require additional factory space. An inlet connector 21, corresponding to the drain connector 19, is integrally formed on the top of the water storage chamber 20. A drain pipe 22 is detachably connected between the inlet connector 21 and the drain connector 19, allowing the collected rainwater to be quickly introduced into the water storage chamber, completing the rainwater transfer. The rear side of the water storage chamber 20 is detachably connected to a cover plate 23 by bolts, which makes it convenient for staff to open the cover plate to clean and maintain the inside of the water storage chamber. The inside of the water storage chamber 20 is fixed with a filter screen 24, which can filter out impurities such as leaves and dust in the rainwater as it flows in, ensuring that the stored rainwater is clean and usable. The inside of the water storage chamber 20 is equipped with an extraction pipe 25 that extends from the top to the outside, which makes it convenient for staff to extract the stored rainwater at any time. The operation is simple and convenient.

[0033] Example 3, referring to Figures 1-8 A method for using a factory building with ventilation and filtration functions includes the following steps:

[0034] S1. Ventilation and filtration operation: Start the fan 10 in the ventilation box 9 to drive the air circulation in the workshop, quickly draw the impurity air in the workshop to the filtration position, and at the same time start the motor 26 to drive the transmission roller 14 to rotate, driving the adhesive cloth belt 15 to circulate and ensure the continuous filtration; when the impurity air in the workshop passes through the channel 11, the lint, dust and impurities in the air are adsorbed and filtered by the adhesive cloth belt 15, quickly purifying the air in the workshop.

[0035] S2. Self-cleaning operation: Synchronously drive the roller brush 31 to clean the adhered cloth belt 15 in real time, and clean the impurities while filtering, avoid clogging the filter port, and ensure that the ventilation system can run continuously.

[0036] S3. Rainwater harvesting operation: When it rains, the rainwater collection tank 18 on the roof 8 collects rainwater from the roof and quickly receives the falling rainwater. The rainwater flows into the water storage chamber 20 through the drain connector 19 and drain pipe 22. After being filtered by the filter screen 24 to remove leaves, dust and impurities, it is stored in the water storage chamber 20, completing the on-site recycling of rainwater.

[0037] S4. Water Reuse Operation: When water is needed, the filtered clean rainwater is extracted through the extraction pipe 25 in the water storage chamber 20 for cleaning of the factory floor or irrigation of the surrounding greenery, realizing the recycling and reuse of rainwater and reducing water costs.

[0038] In S2, while the second transmission roller 14 drives the adhesive cloth belt 15, it simultaneously drives the first transmission roller 13 to rotate. The synchronous operation of the two transmission rollers can be achieved without additional power. The first transmission roller 13 drives the gear 27 at both ends to rotate, and through the meshing gear 29, it drives the roller brush 31 to rotate synchronously, thereby achieving power synchronization of filtration and cleaning. The roller brush 31 removes lint and impurities from the adhesive cloth belt 15 in real time, ensuring the synchronicity of cleaning actions from the power perspective and preventing the problem of misalignment between filtration and cleaning. The brushed-off lint and dust fall into the dust collection hopper at the bottom of the ventilation box for centralized storage, and the operator can clean the dust collection hopper regularly.

[0039] Working principle: The main body of the factory building is based on the base 1. The lower surface of the base 1 is fixed with four corner plugs 2. The outer side of the plugs 2 is detachably connected to the pile foundation 3 by bolts. The upper surface is detachably connected to the mounting frame 4 by bolts. The front, right, left, rear and top of the mounting frame 4 are respectively detachably connected to the front wall panel 5, right wall panel 6, left wall panel 7, rear wall panel 32 and roof 8 by bolts. All components can be prefabricated in the factory and quickly assembled on site to achieve modular assembly. The left wall panel 7 is embedded with a ventilation box 9. The ventilation box 9 is equipped with a fan 10, which can drive the air circulation in the workshop. The ventilation box 9 is provided with a channel 11 for the workshop air to pass through. The lower surface of the ventilation box 9 is fixed with a mounting frame 12. The mounting frames 12 are rotatably connected to the transmission roller 13. The ventilation box 9 is correspondingly provided with a transmission roller 14. The two transmission rollers are connected to the adhesive cloth belt 15. When the workshop air containing impurities passes through the channel 11, the lint and dust impurities in the air will be absorbed and filtered by the adhesive cloth belt 15. A motor 26 is fixed to the rear of the ventilation box 9. The output shaft of the motor 26 is connected to the transmission roller 14, which can drive the transmission roller 14 to rotate, thereby driving the adhesive cloth belt 15 to rotate in a cycle. At the same time, the transmission roller 13 is driven to rotate synchronously by the adhesive cloth belt 15. The filter assembly also includes a gear 27, a bearing 28, a gear 29, and a shaft 30. The gear 27 is fixed to both ends of the transmission roller 13. The bearing 28 is fixed to the bottom of the mounting frame 12. The gear 29 is rotatably mounted on the bearing 28 and meshes with the gear 27. The shaft 30 is fixedly connected between the two gears 29. The roller brush 31 is coaxially fixed on the shaft 30. The roller brush 31 is just in contact with the outer wall of the adhesive cloth belt 15. When the gear 27 rotates, it will drive the gear 29 to rotate synchronously, thereby driving the roller brush 31 to rotate, brushing away the lint and impurities on the adhesive cloth belt 15 in real time, realizing the automatic cleaning of the filter assembly and avoiding the clogging of the filter port.

[0040] The roof 8 has an integrally formed water collection trough 18 on its upper surface, which can collect rainwater from the roof during rain. The rear side of the roof 8 has an integrally formed drain connector 19. The rear side of the rear wall panel 32 has a water storage cavity 20 fixed. The top of the water storage cavity 20 has an integrally formed inlet connector 21 corresponding to the drain connector 19. The inlet connector 21 and the drain connector 19 are detachably connected to a drain pipe 22. The collected rainwater can flow into the water storage cavity 20 through the drain connector 19 and the drain pipe 22. The rear side of the water storage cavity 20 is detachably connected to a cover plate 23 by bolts. The front side of the cover plate 23, located inside the water storage cavity 20, has a filter screen 24 fixed. When the rainwater flows into the water storage cavity 20, it will first pass through the filter screen 24 to filter out impurities such as leaves and dust before being stored in the water storage cavity 20. When the factory area is large, there can be two drain connectors 19, corresponding to the two inlet connectors 21 on the top of the water storage cavity 20, to improve the efficiency of rainwater discharge and recycling. In daily use, starting the fan 10 and motor 26 will automatically complete the filtration and self-cleaning of the workshop air. When water is needed, the filtered clean rainwater can be extracted through the extraction pipe 25 inside the water storage chamber 20 for cleaning the factory floor or irrigating the surrounding greenery, realizing the recycling and reuse of rainwater and reducing the operating cost of the factory.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
