Description

Technical Field

[0001] This invention relates to the field of air purification technology, specifically to an air purification device for wood furniture processing. Background Technology

[0002] In the production of wooden furniture, multiple processes such as sawing, polishing, or surface painting are usually required. In the workshop, sawing and sanding processes generate wood dust, while painting processes generate harmful exhaust gases. To ensure the safety of workers in the workshop and to prevent external air pollution, appropriate air purification equipment is usually used to purify the air inside the workshop.

[0003] For example, the exhaust gas purifier for a solid wood furniture production workshop, as disclosed in announcement number CN220656966U, includes a purifier housing and exhaust gas inlets and outlets at its two ends. The top of the purifier housing is provided with multiple sealing grooves at equal intervals near the outlets. Each sealing groove is connected to a rubber ring, and each rubber ring is fitted with a sealing cover plate. Multiple activated carbon filter plates are vertically inserted into the purifier housing, and after multiple layers of filtration and adsorption, harmful substances in the exhaust gas are absorbed.

[0004] The existing technology has the following technical problems: When the existing purification equipment purifies the exhaust gas inside the furniture workshop, it uses filter components in the internal filter channel of the purification equipment to filter out pollutants in the air. However, the filter channel inside the purification equipment is single. Because the required purification precision of pollutants in the air is different when furniture is processed in different processes in the workshop, the single filter channel cannot switch the filtration mode according to different processes.

[0005] Therefore, we propose an air purification device for wooden furniture processing to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an air purification device for wood furniture processing, in order to solve the problem mentioned in the background art that existing purification devices on the market, when purifying the exhaust gas inside the furniture workshop, use filter components in the internal filtration channel of the purification device to filter out pollutants in the air. However, the internal filtration channel of the purification device is single, and when the filter components in the filtration channel need maintenance, the entire device needs to be shut down, resulting in a decrease in overall production efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an air purification device for wood furniture processing, comprising a supporting housing and an air inlet pipe and an air outlet pipe respectively installed on the upper and lower sides of the supporting housing, wherein the air outlet pipe is connected to an external negative pressure device, a partition plate is installed in the middle of the supporting housing, and the partition plate divides the internal space of the supporting housing into a first purification chamber and a second purification chamber, both of which are equipped with purification components, and a first branch pipe and a second branch pipe are installed on the air inlet pipe, wherein the first branch pipe is connected to the first purification chamber. The second branch pipe is connected to the second purification chamber. The outlet pipe is equipped with a third branch pipe and a fourth branch pipe. The third branch pipe is connected to the first purification chamber, and the fourth branch pipe is connected to the second purification chamber. A first electromagnetic on / off valve is installed on the first, second, third, and fourth branch pipes. A convection pipe is installed on the partition plate, and a second electromagnetic on / off valve is installed on the convection pipe. By switching the first and second electromagnetic on / off valves on and off, the automatic switching between the series purification path and the parallel purification path of the first and second purification chambers can be realized.

[0008] Preferably, the third branch pipe on the exhaust pipe and the first branch pipe on the intake pipe are located on the left and right sides of the purification component inside the first purification chamber, respectively, and the fourth branch pipe on the exhaust pipe and the second branch pipe on the intake pipe are located on the left and right sides of the purification component inside the second purification chamber, respectively.

[0009] By adopting the above technical solution, when the first electromagnetic on / off valve on the second branch pipe and the fourth branch pipe is closed, the airflow can only flow inside the first purification chamber.

[0010] Preferably, the convection pipe is used to connect the first purification chamber and the second purification chamber inside the support housing, and at least one convection pipe is installed on the partition plate.

[0011] By adopting the above technical solution, when the second electromagnetic on / off valve on the convection pipe is opened, the airflow purified inside the first purification chamber can enter the interior of the second purification chamber through the convection pipe for further purification.

[0012] Preferably, the purification component has a receiving groove, and a purification cover is fixed inside the receiving groove, with through holes on both the left and right sides of the purification cover.

[0013] By adopting the above technical solution, the airflow can enter through the through-hole on one side of the purification hood and then be discharged outward through the through-hole on the other side.

[0014] Preferably, multiple purification hoods are evenly distributed at equal angles on the purification component, and each purification hood corresponds to a receiving groove, and the air purification substrate inside each purification hood is different.

[0015] By adopting the above technical solution and using different air purification substrates inside the purification hood, adjustments can be made according to the polluted air requiring different purification precision.

[0016] Preferably, a servo motor is installed at the end of the supporting housing, and a transmission rod is installed on the output end of the servo motor. The transmission rod is installed through the middle of the purification components inside the first and second purification chambers. Baffles are installed on both the left and right sides of the purification components inside the first and second purification chambers, and the baffles are connected to the transmission rod through one-way bearings. A guide port is provided on the baffle, and the guide port corresponds to one of the purification hoods on the purification component.

[0017] By adopting the above technical solution, the position of the guide port can be adjusted by rotating the baffle plate so that the guide port corresponds to one of the purification hoods on the purification component.

[0018] Preferably, the locking direction of the one-way bearings connected to the transmission rod at the middle of the left and right side shields of the first purification chamber is opposite to the locking direction of the one-way bearings connected to the transmission rod at the middle of the left and right side shields of the second purification chamber, so that the shields can rotate on the purification component.

[0019] By adopting the above technical solution, and by using different locking directions of the one-way bearings, it is possible to easily rotate and adjust the purification hoods on the purification components inside the first and second purification chambers individually, thereby achieving stepped deep filtration when forming a series purification path.

[0020] Preferably, the baffle plate is in contact with the purification hood on the purification component in the initial state, and the surfaces of the purification hood and the purification component are flush with each other.

[0021] By adopting the above technical solution, the shielding plate and the purification hood are attached to each other, and after the guide port on the shielding plate corresponds to one of the purification hoods, the shielding plate is used to block and seal the through holes on the surface of the other purification hoods.

[0022] Preferably, drive cylinders are installed on the front and rear sides of the support housing, and positioning pressure members are installed on the telescopic ends of the drive cylinders. The positioning pressure members are used to fix the rotated baffle plate.

[0023] By adopting the above technical solution, the opening of the drive cylinder can be used to press the side of the baffle plate with the positioning pressure component, thereby preventing the baffle plate from rotating on its own.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the air purification device for wood furniture processing has two filter chambers set inside the purification shell. The two filter chambers can be switched between parallel operation and series operation modes. In the parallel operation mode, the maintenance of one filter chamber does not affect the operation of the other filter chamber. In the series operation mode, the filter chamber can be used for exhaust gas purification that requires higher filtration accuracy.

[0025] 1. By controlling the opening and closing of the first electromagnetic on / off valve on the first branch pipe, the second branch pipe, the third branch pipe and the fourth branch pipe, the first purification chamber and the second purification chamber can be operated independently in parallel. At this time, when the first purification chamber or the second purification chamber is performing the purification process, it does not affect the maintenance of the purification substrate inside the other purification chamber. At the same time, opening the second electromagnetic on / off valve on the convection pipe can realize the parallel operation of the first purification chamber and the second purification chamber, thereby deeply purifying the polluted air.

[0026] 2. By matching the guide port on the baffle plate with the purification hood on the purification component, the purification substrate can be reasonably selected according to different processing procedures. At the same time, by using the one-way locking characteristic of the one-way bearing, the purification hoods inside the first and second purification chambers can be adjusted asynchronously. When performing series purification work, two different air purification substrates can be selected to perform step-by-step deep purification of polluted air. Attached Figure Description

[0037] 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.

[0038] Example 1: Please refer to Figures 1-9Existing purification equipment, when purifying exhaust gas inside furniture workshops, uses filter components installed in the internal filtration channels of the equipment to remove air pollutants. However, the internal filtration channels of the purification equipment are singular. Because the required purification precision of air pollutants varies when furniture is processed in different stages of the workshop, a single filtration channel cannot switch filtration modes according to different processes. To solve this technical problem, this embodiment discloses the following technical content: an air purification device for wooden furniture processing, including a supporting housing 1 and components respectively installed on the supporting housing 1. The support housing 1 has an inlet pipe 2 and an outlet pipe 3 on its upper and lower sides. The outlet pipe 3 is connected to an external negative pressure device. A partition plate 4 is installed in the middle of the support housing 1, which divides the internal space of the support housing 1 into a first purification chamber 5 and a second purification chamber 6. Purification components 7 are installed inside both the first purification chamber 5 and the second purification chamber 6. A first branch pipe 8 and a second branch pipe 9 are installed on the inlet pipe 2. The first branch pipe 8 is connected to the first purification chamber 5, and the second branch pipe 9 is connected to the second purification chamber 6. A third branch pipe 10 and a fourth branch pipe 10 are installed on the outlet pipe 3. Pipe 11, and the third branch pipe 10 is interconnected with the first purification chamber 5, and the fourth branch pipe 11 is interconnected with the second purification chamber 6. A first electromagnetic on / off valve 12 is installed on each of the first branch pipe 8, second branch pipe 9, third branch pipe 10, and fourth branch pipe 11. A convection pipe 13 is installed on the partition plate 4, and a second electromagnetic on / off valve 14 is installed on the convection pipe 13. By switching the first electromagnetic on / off valve 12 and the second electromagnetic on / off valve 14, the automatic switching between the series purification path and the parallel purification path of the first purification chamber 5 and the second purification chamber 6 is achieved. The third branch pipe 3 on the exhaust pipe 3... The first branch pipe 8 on the branch pipe 10 and the first branch pipe 8 on the inlet pipe 2 are located on the left and right sides of the purification component 7 inside the first purification chamber 5, respectively. The fourth branch pipe 11 on the outlet pipe 3 and the second branch pipe 9 on the inlet pipe 2 are located on the left and right sides of the purification component 7 inside the second purification chamber 6, respectively. The convection pipe 13 is used to connect the first purification chamber 5 and the second purification chamber 6 inside the support housing 1. At least one convection pipe 13 is installed on the partition plate 4. The purification component 7 is provided with a receiving groove 15, and a purification cover 16 is fixed inside the receiving groove 15. Through holes are provided on both the left and right sides of the purification cover 16.

[0039] When furniture is polished or sanded in the workshop, the resulting dust mixes with the air. Since the required precision for dust filtration is relatively low, closing the first solenoid valve 12 on the second branch pipe 9 and the first solenoid valve 12 on the fourth branch pipe 11 allows negative pressure suction from an external negative pressure device to allow polluted air from the workshop to enter the first purification chamber 5 through the air inlet pipe 2 and the first branch pipe 8. The dust in the air is filtered by the purification hood 16 on the purification component 7 inside the first purification chamber 5, and the filtered air is discharged outwards through the third branch pipe 10 and the air outlet pipe 3. At the same time, the first electromagnetic on / off valve 12 on the first branch pipe 8 and the first electromagnetic on / off valve 12 on the third branch pipe 10 can be closed. At this time, the polluted air can enter the interior of the second purification chamber 6 through the air inlet pipe 2 and the second branch pipe 9. The dust in the air is filtered by the purification cover 16 on the purification component 7 inside the second purification chamber 6. Thus, the first purification chamber 5 and the second purification chamber 6 can work in parallel. In the parallel manner, when the first purification chamber 5 or the second purification chamber 6 is working, it does not affect the maintenance of the air purification substrate in the purification cover 16 inside the other purification chamber.

[0040] When the workshop needs to spray paint furniture, the pollution generated during the spraying process is mixed in with the air, requiring a relatively high level of purification precision. At this time, the first electromagnetic shut-off valve 12 on the second branch pipe 9 and the third branch pipe 10 is closed, and the second electromagnetic shut-off valve 14 on the convection pipe 13 is opened. At this time, the first purification chamber 5 and the second purification chamber 6 are connected to each other and work in series. The polluted air from the outside enters the first purification chamber 5 through the air inlet pipe 2 and the first branch pipe 8. The polluted air is first adsorbed and purified by the purification hood 16 on the purification component 7 inside the first purification chamber 5. Then, the air after the first purification enters the interior of the second purification chamber 6 through the convection pipe 13. The polluted air is adsorbed again by the purification hood 16 on the purification component 7 inside the second purification chamber 6. The air after the two adsorption and purification processes is finally discharged to the outside through the fourth branch pipe 11 and the air outlet pipe 3, thereby achieving deep purification of the polluted air.

[0041] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. To improve the deep purification of gases requiring high purification precision, the following technical content is disclosed in this example: Figures 3-7As shown, multiple purification hoods 16 are evenly distributed at equal angles on the purification component 7, and each purification hood 16 corresponds one-to-one with the receiving groove 15. The air purification substrate inside each purification hood 16 is different. A servo motor 17 is installed at the end of the supporting housing 1, and a transmission rod 18 is installed on the output end of the servo motor 17. The transmission rod 18 is installed through the middle of the purification component 7 inside the first purification chamber 5 and the second purification chamber 6. Baffle plates 19 are installed on both the left and right sides of the purification component 7 inside the first purification chamber 5 and the second purification chamber 6. The baffle plates 19 are connected to the transmission rod 18 via one-way bearings. A guide port 20 is provided on the baffle plate 19, and the guide port 20 connects to one of the baffle plates 7. A purification hood 16 is provided for each other. The locking direction of the one-way bearing connected to the transmission rod 18 in the middle of the baffle 19 on both sides of the purification component 7 inside the first purification chamber 5 is opposite to the locking direction of the one-way bearing connected to the transmission rod 18 in the middle of the baffle 19 on both sides of the purification component 7 inside the second purification chamber 6. The baffle 19 can rotate on the purification component 7. In the initial state, the baffle 19 is in contact with the purification hood 16 on the purification component 7, and the surfaces of the purification hood 16 and the purification component 7 are flush with each other. Drive cylinders 21 are installed on the front and rear sides of the support housing 1, and positioning pressure members 22 are installed on the extension and retraction ends of the drive cylinders 21. The positioning pressure members 22 are used to fix the baffle 19 after rotation.

[0042] Because multiple purification hoods 16 are installed on the purification component 7, and each purification hood 16 is filled with a different air purification substrate, the air purification substrate can be selectively filled and installed according to the actual processing type in the workshop. The servo motor 17 can be turned on, and the transmission rod 18 can be rotated after the servo motor 17 is turned on. After the transmission rod 18 rotates towards the locking direction of the one-way bearing, the one-way bearing can drive the baffle plate 19 to rotate synchronously. After the baffle plate 19 rotates, it can drive the guide port 20 on it to rotate synchronously. After the guide port 20 rotates, it is aligned with the different purification hoods 16 on the purification component 7, so that the purification substrate can be selected and adjusted in a controllable manner according to the actual processing scenario. After the baffle plate 19 is rotated into place, the drive cylinder 21 is turned on. After the drive cylinder 21 is turned on, it can push the positioning pressure component 22, so that the positioning pressure component 22 presses the baffle plate 19 tightly, thereby ensuring the stability of the baffle plate 19 when it is stationary.

[0043] When the first purification chamber 5 and the second purification chamber 6 operate in series, because the one-way bearings connecting the side baffles 19 of the purification components 7 inside the first and second purification chambers 5 and 6 are locked in opposite directions to the transmission rod 18, the servo motor 17 can be used to first control the transmission rod 18 to rotate clockwise. After the transmission rod 18 rotates clockwise, it can rotate towards the locking direction of the one-way bearing inside the first purification chamber 5, and after the transmission rod 18 rotates clockwise, it can rotate towards the non-locking direction of the one-way bearing inside the second purification chamber 6. At this time, the rotation of the transmission rod 18 can first drive the purification components 7 inside the first purification chamber 5. The side baffle 19 is rotated so that the guide port 20 on the baffle 19 aligns with one of the purification hoods 16. Then, the servo motor 17 controls the transmission rod 18 to rotate counterclockwise. At this time, the transmission rod 18 drives the baffle 19 on the side of the purification component 7 inside the second purification chamber 6 to rotate, but does not drive the baffle 19 on the side of the purification component 7 inside the first purification chamber 5 to rotate. This achieves asynchronous adjustment of the purification hoods 16 inside the first purification chamber 5 and the second purification chamber 6. When performing series purification, two different air purification substrates can be selected to perform step-by-step deep purification of polluted air.

[0044] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
