DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] Embodiment 1, the present invention provides as follows Figures 1 to 11 A dust removal device for a furniture production workshop is shown, comprising a dust removal component 1. There are multiple dust removal components 1, which are connected in parallel. When any dust removal component 1 is blocked, the others can still work normally to prevent the equipment from stopping and affecting production. It is installed outside the production workshop. An exhaust fan 2 is fixedly installed on one side of the dust removal component 1, and is used to extract the air containing sawdust and dust inside the production workshop and transport it to the dust removal component 1 for treatment. A dust removal pipe 3 is connected to the output end of the exhaust fan 2, and the other end is connected to the dust removal component 1. A main air duct 4 is connected to the input end of the exhaust fan 2, and multiple auxiliary air ducts 5 are fixedly installed on the outside of the main air duct 4. The exhaust fan 2 is used to extract the air containing sawdust and dust inside the production workshop and transport it to the dust removal component 1 for treatment.

[0034] Specifically, the dust removal assembly 1 includes a dust removal box 10, which is a cylindrical structure with an opening facing downward. A separation box 11, which is fixedly connected to the bottom of the dust removal box 10 and is a conical structure with openings at both ends. The upper opening diameter of the separation box 11 is larger, and the lower diameter is smaller. A discharge pipe 12, which is fixedly connected to the lower end of the separation box 11, is used to discharge the filtered dust particles. A receiving box 13, which is fixedly connected to the lower end of the discharge pipe 12, is used to collect the discharged dust particles. The dust particles flowing out of the discharge pipe 12 will enter the receiving box 13 under gravity. One side of the receiving box 13 can be opened to clean the dust particles stored inside. A dust separation assembly 14, which is fixedly connected to the upper end of the dust removal box 10, is used to filter dust. A recoil assembly 15, which is fixedly connected to the upper end of the dust removal box 10, includes an oscillation assembly 150, which is used to clean the dust outside the dust separation assembly 14.

[0035] It should be pointed out that the dust separation assembly 14 includes a partition 140, a mounting groove 141, a through groove 142, a mounting seat 143 and a dust bag 144. The partition 140 is fixedly installed inside the dust removal box 10. The mounting groove 141 is opened on the upper surface of the partition 140. The through groove 142 runs through the middle of the groove bottom opened in the mounting groove 141. The mounting seat 143 is plugged and installed inside the mounting groove 141, and the mounting seat 143 is set as an annular structure. The through groove 142 and the mounting groove 141 form a stepped groove shape, so that the mounting seat 143 can be confined in the mounting groove 141. The dust bag 144 is fixedly installed at the bottom end of the mounting seat 143. The side wall of the dust bag 144 can block dust particles and allow air to penetrate the side wall into the dust bag 144, as shown in the state 10 (a) in Figure 10, and the dust bag 144 runs through the inside of the through groove 142.

[0036] Specifically, a connecting seat 145 is provided below the mounting seat 143, and a plurality of limit plates 146 are fixedly connected between the connecting seat 145 and the mounting seat 143. The plurality of limit plates 146 are all arranged in an arc structure, and the limit plates 146 are connected to the connecting seat 145 by screws. The limit plates 146 are evenly distributed in a circle on the outside of the dust bag 144, and the limit plates 146 are used to limit the expansion of the dust bag 144. The connecting seat 145 is detachable, which facilitates the disassembly and replacement of the dust bag 144. The connecting seat 145 can protect the bottom end of the dust bag 144 to prevent the dust bag 144 from deforming from bottom to top.

[0037] More specifically, the recoil assembly 15 includes a recoil pipe 151, a three-way pipe 152, a compressed gas tank 153 and a pulse valve 154. The pulse valve 154 is connected to a controller and a power supply to achieve rapid conduction / closing. There are multiple recoil pipes 151, and the recoil pipes 151 are respectively fixedly installed inside the corresponding mounting seat 143, and the bottom end of the recoil pipe 151 is placed on the inner side of the dust bag 144. The recoil pipe 151 is connected to the dust bag 144. The three-way pipe 152 is fixedly installed at the top of the recoil pipe 151, and multiple recoil pipes 151 are respectively connected to the three-way pipe 152. The compressed gas tank 153 is fixedly installed on the outside of the dust removal box 10. The pulse valve 154 is fixedly installed at the output end of the compressed gas tank 153. The compressed gas tank 153 stores high-pressure gas, and the pulse valve 154 and the three-way pipe 152 are connected through a hose.

[0038] During use, the pulse valve 154 is controlled to be turned on so that the gas in the compressed gas tank 153 enters the three-way pipe 152 and the recoil pipe 151 , and the dust removal bag 144 is cleaned through the recoil pipe 151 .

[0039] Specifically, the recoil assembly 15 also includes a support frame 155, which is fixedly connected to the lower end of the recoil pipe 151 and placed on the inner side of the dust bag 144. A hole is opened in the middle of the support frame 155 to connect the recoil pipe 151 with the dust bag 144. There are multiple support plates 156, which are evenly distributed in a circle and fixedly connected to the lower end of the support frame 155. The lower ends of the multiple support plates 156 are fixedly connected. The support plates 156 support the inner wall of the dust bag 144 to prevent the dust bag 144 from being affected by the airflow and causing the inner wall to fit when the dust removal work is performed, so that air cannot enter the dust bag 144. The plug rod 157 is slidably connected to the middle part of the support frame 155, and a movable plug 158 is fixedly connected to the lower end. The movable plug 158 corresponds to the hole opened in the middle part of the support frame 155. The movable plug 158 is used to seal the recoil pipe 151 in one direction. The return spring 159 is sleeved on the outside of the insertion rod 157 , with the top end fixedly connected to the insertion rod 157 and the bottom end fixedly connected to the top of the support frame 155 .

[0040] During the recoil cleaning process, the gas in the recoil pipe 151 pushes the movable plug 158, allowing the gas to enter the dust bag 144, so that the dust particles on the outside of the dust bag 144 are separated, thereby achieving the unblocking of the dust bag 144. After the unblocking is completed, the reset spring 159 pushes the insertion rod 157 and the movable plug 158 to reset, and the movable plug 158 blocks the hole in the middle of the support frame 155.

[0041] More specifically, the oscillation assembly 150 includes a trigger rod 1501, which is slidably disposed in the insertion rod 157 and penetrates the lower end of the insertion rod 157. The upper end of the trigger rod 1501 is fixedly connected to a support spring 1502, and the other end of the support spring 1502 contacts the inner wall of the insertion rod 157. A trigger portion 1503 is disposed and fixedly connected in the insertion rod 157, and the trigger position faces the upper end of the trigger rod 1501. The trigger portion 1503 is electrically connected to the pulse valve 154, and the trigger portion 1503 is electrically connected to the controller. The trigger portion 1503 can be a micro switch or a pressure sensor, etc., which can generate an electrical signal after being pressed. When the trigger portion 1503 is triggered, the controller turns on the pulse valve 154. There are multiple elastic sheets 1504, which are staggered with the support plate 156. The lower end of the elastic sheet 1504 is fixedly connected to the support plate 156, and the upper end passes through the support frame 155 and can slide relative to the support frame 155, and is used to beat the inner side of the dust bag 144. The elastic sheet 1504 has a certain toughness. When the dust bag 144 is affected by air pressure and deforms inward, it will squeeze the elastic sheet 1504 to bend inward. The trigger link 1505 is rotatably connected to the middle part of the elastic sheet 1504, and the upper end is rotatably connected to the bottom of the trigger rod 1501, and is used to push the elastic sheet 1504 to deform.

[0042] It should be noted that when the dust bag 144 is blocked during operation, it will shrink inwards due to the airflow. At this time, the dust bag 144 squeezes the elastic sheet 1504 to bend inwards. Fig.10 In the state (b), the trigger connecting rod 1505 pushes the trigger rod 1501 to slide upward, and makes the trigger rod 1501 press the trigger part 1503. When the trigger part 1503 is triggered, the controller makes the pulse valve 154 quickly switch on / off alternately; when the pulse valve 154 is turned on, the airflow pushes the plug rod 157 to slide downward. In this process, the trigger connecting rod 1505 pushes the elastic sheet 1504 to deform, as shown in FIG. Fig.10 In the middle (c) state, the elastic sheet 1504 pushes the dust bag 144 to expand outward, and then the pulse valve 154 is closed. The elastic sheet 1504 is reset due to its own toughness, and the dust bag 144 returns to a normal state. The pulse valve 154 is repeatedly turned on / off quickly, so that the dust bag 144 can be beaten, the dust particles on the outside of the dust bag 144 fall off, and the dust bag 144 is unblocked.

[0043] It should be noted that when the pulse valve 154 is turned on, the pressure inside the separation box 11 increases due to the entry of air from the compressed gas tank 153; when the pulse valve 154 is closed, the pressurized gas inside the separation box 11 enters the inspection cover 16 through the unblocked dust bag 144, and is then discharged. During the rapid alternating opening / closing of the pulse valve 154, the pressure inside the separation box 11 changes only slightly, and does not cause the pressure inside the separation box 11 to continue to increase, resulting in the problem of being unable to recoil the dust bag 144.

[0044] Specifically, the dust removal assembly 1 also includes an inspection cover 16, an exhaust fan 17 and an exhaust duct 18. The inspection cover 16 is fixedly installed on the top of the dust removal box 10, and the mounting seat 143 is placed on the lower side of the inspection cover 16. The inspection cover 16 is a hollow structure, and the mounting seat 143 is connected to the inspection cover 16. The exhaust fan 17 is fixedly installed in the middle of the top of the inspection cover 16, and the exhaust duct 18 is fixedly installed at the output end of the exhaust fan 17. The exhaust fan 17 and the exhaust duct 18 can extract pure air to improve the efficiency of air passing through the dust removal bag 144.

[0045] More specifically, an air intake pipe 19 is fixedly installed on the outside of the separation box 11, and the air intake pipe 19 is installed at the tangent of the inner wall of the separation box 11. The air intake pipe 19 is connected to the separation box 11 and the dust removal pipe 3. The design of the tangent position allows the air to spiral along the inner wall of the separation box 11 after entering the separation box 11, so that the amount of air received by each powder dust removal bag 144 is almost the same.

[0046] It should be noted that a one-way valve 20 is fixedly connected to the middle of the air inlet pipe 19 to prevent the air containing dust particles from being blown back to the production workshop when the dust removal bag 144 is back-blown and cleaned.

[0047] In summary, when the device is in use, the air containing wood chips and dust in the furniture production workshop is drawn into the dust removal pipe 3 through the exhaust fan 2, the main air duct 4 and the auxiliary air duct 5, and then transported to the interior of the separation box 11 through the air intake pipe 19. The air rises along the inner wall of the separation box 11. After the air moves to the top of the separation box 11, the air will penetrate the dust bag 144, and then continue to rise and enter the inspection cover 16, and then be extracted and discharged to the outside through the exhaust fan 17 and the exhaust pipe 18. At the same time, the dust particles will be blocked by the side walls of the dust bag 144, making it impossible to be discharged. At the same time, the dust particles on the outside of the dust bag 144 will fall downward due to the influence of gravity, and then enter the receiving box 13 through the discharge pipe 12.

[0048] When the outside of the dust bag 144 is blocked, the exhaust fan 17 and the exhaust fan 2 are turned off. At the same time, the side wall of the dust bag 144 will bend inward under the influence of the airflow, thereby squeezing the elastic sheet 1504 to bend inward, so that the trigger rod 1501 presses the trigger part 1503, and the controller makes the pulse valve 154 quickly switch on / off; when the pulse valve 154 is turned on, the gas in the recoil pipe 151 pushes the active plug 158, so that the gas enters the dust bag 144, so that the dust particles on the outside of the dust bag 144 are separated, thereby achieving the purpose of dredging the dust bag 144. The pulse valve 154 works smoothly, and during this process, the trigger link 1505 pushes the elastic sheet 1504 to deform to the side away from the trigger rod 1501, so that the elastic sheet 1504 pushes the dust bag 144 to expand outward; when the pulse valve 154 is closed, the elastic sheet 1504 is reset due to its own toughness, and the dust bag 144 returns to a normal state; by repeatedly turning the pulse valve 154 on / off quickly, the dust bag 144 can be beaten, so that the dust particles on the outside of the dust bag 144 fall off, thereby improving the dredging effect of the dust bag 144.

[0049] When the pulse valve 154 is closed, the plug 157, the movable plug 158, the trigger rod 1501 and the elastic sheet 1504 are all reset synchronously. When the reset trigger rod 1501 no longer squeezes the trigger part 1503, it indicates that the dust bag 144 is unblocked, and the exhaust fan 17 and the exhaust fan 2 can be started to keep the device running. The pulse valve 154 can also be quickly turned on / off for a period of time through the controller to beat the dust bag 144 for dust removal. After the set time is reached, the controller determines whether the reset trigger rod 1501 squeezes the trigger part 1503. If it still squeezes the trigger part 1503, the elastic sheet 1504 is made to beat the dust bag 144 for a period of time again. If the trigger part 1503 is no longer squeezed, it indicates that the dust bag 144 is unblocked, and the exhaust fan 17 and the exhaust fan 2 can be started to keep the device running.

[0050] Embodiment 2, the present invention also discloses a dust removal method for a dust removal device used in a furniture production workshop, comprising the following steps: Step 1: Equipment installation: install the dust removal component 1 outside the production workshop, install the main air duct 4 and the auxiliary air duct 5 inside the production workshop, and install multiple auxiliary air ducts 5 near multiple equipment in the production workshop; Step 2: Dust removal: The air with wood chips and dust inside the production workshop is extracted through the exhaust fan 2 and the main air duct 4, and the air is transported to the dust removal component 1 through the dust removal pipe 3. The air drives the wood chips and dust to spiral upward inside the dust removal component 1. The wood chips move downward into the receiving box 13 under the action of gravity. The dust is isolated on the outside of the dust removal bag 144, and the purified air is discharged; Step three, equipment cleaning: by controlling the exhaust fan 17 and the exhaust fan 2 to stop, and delivering the compressed air in the compressed gas tank 153 to the dust bag 144, the dust bag 144 expands rapidly, and the elastic sheet 1504 is used to beat the dust bag 144 to shake off the dust on the outside of the dust bag 144, thereby achieving the self-cleaning effect of the dust bag 144, and cleaning the wood chips and dust collected in the collecting box 13, the equipment can be cleaned.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
