Description

Technical Field

[0001] This invention belongs to the technical field of dust removal devices for decoration, specifically referring to a dust collection device for indoor decoration. Background Technology

[0002] During interior decoration, tasks such as wall sanding and panel cutting generate a lot of dust. This dust not only pollutes indoor air and harms the health of construction workers, but also affects the quality of the decoration.

[0003] Currently, most commonly used dust collection devices employ a single filter element structure, which cannot automatically initiate dust removal based on the filter element's clogging status, and a single airflow backflushing method is insufficient to remove dust accumulated on the filter element's surface and inside.

[0004] Therefore, there is a need for a dust collection device for interior decoration to solve the technical problems in the prior art that cannot be cleaned according to the filter element clogging status and that it is difficult to remove dust accumulated on the surface and inside of the filter element by a single airflow backflushing. Summary of the Invention

[0005] In response to the above situation and to overcome the shortcomings of the prior art, this invention provides a dust collection device for indoor decoration. This application utilizes a fan to draw in air, which drives the dust-laden air through a filter element for filtration. Clean air enters the air chamber for storage. When the filter element is normal, the connection between the air chamber and the rotating box is blocked. When the filter element is clogged and the airflow is insufficient, the air chamber and the rotating box are connected. This solves the technical problem in the prior art that it is impossible to clean the dust according to the filter element's clogging status. The stored high-pressure clean airflow is used for multiple cleaning processes, including high-pressure airflow backflushing, rotary jetting, and mechanical knocking. This solves the technical problem in the prior art that a single airflow backflushing method is insufficient to remove dust accumulated on the surface and inside of the filter element.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present solution proposes a dust collection device for indoor decoration, comprising a dust collection cylinder, which is hollow. A collecting hood is fixedly connected to the top wall of the dust collection cylinder, and a fan is rotatably connected inside the collecting hood. A dust hopper is fixedly connected to the lower inner wall of the dust collection cylinder, and an air chamber is fixedly connected to the outer circumferential wall of the dust collection cylinder. The top of the collecting hood is connected to the input end of the air chamber. A partition plate is fixedly connected to the inner wall of the dust collection cylinder, dividing the internal space of the dust collection cylinder into a dust-free chamber and a dust chamber. The dust-free chamber is connected to the collecting hood. Air inlets are arranged in a circular array on the dust collection cylinder, and the dust chamber is connected to the outside air through the air inlets. A filter element is connected between the bottom wall of the partition plate and the top wall of the dust hopper, and the filter element is located inside the dust chamber. A pusher plate is connected to the top wall of the dust collection cylinder, and a rotating box is rotatably connected to the bottom wall of the pusher plate. The rotating box is hollow, and the top wall of the pusher plate is connected to the output end of the air chamber.

[0007] Preferably, the top wall of the push plate is symmetrically and fixedly connected with a push spring to the top wall of the dust collector cylinder, the outer edge of the bottom wall of the push plate is set with an inclined edge, the top wall of the partition plate is coaxially and fixedly connected with a contact ring, one side of the outer edge of the top wall of the contact ring is set with an inclined edge, the outer edge of the bottom wall of the push plate and the outer edge of the top wall of the contact ring are fitted together, and a through hole is coaxially and through the push plate, the through hole being connected to the air bag output end through an air pipe.

[0008] Preferably, nozzles are fixedly connected in a ring array on the outer circumferential wall of the rotating box, and the nozzles are tangential to the outer circumferential wall of the rotating box. An air inlet is coaxially connected to the top wall of the rotating box, and the air inlet is connected to a connecting hole. A rotating cover is coaxially fixedly connected to the bottom wall of the rotating box. An I-beam is longitudinally slidably connected to the bottom wall of the rotating box and the top wall of the rotating cover. A driving spring is sleeved in the middle of the I-beam, and the two ends of the driving spring are fixedly connected to the other end of the I-beam and the inner bottom wall of the rotating box, respectively.

[0009] Preferably, the rotating cover is slidably connected in a ring array with striking rods, one end of the striking rods extending out of the rotating cover, and the other end of the striking rods is fitted with striking springs. The two ends of the striking springs are respectively fixedly connected to the other end of the striking rods and the inner circumferential wall of the rotating cover. The bottom wall of the partition plate is fixedly connected in a ring array with guide blocks, which are located inside the filter element and are arranged in an arc shape.

[0010] Preferably, the top wall of the air collecting hood is fixedly connected to an air outlet pipe, the other end of the air outlet pipe is fixedly connected to a three-way valve, the other two ends of the three-way valve are respectively fixedly connected to a one-way valve and a pressure valve, and the one-way valve is connected to the input end of the air bag through an air pipe.

[0011] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This application utilizes a fan to draw in air, which drives the dust-laden air through the filter element for filtration. Clean air enters the air tank for storage. The system automatically determines the filter element clogging status. When the filter element is normal, the connection between the air tank and the rotating box is blocked. When the filter element is clogged and the airflow is insufficient, the air tank is connected to the rotating box. The stored high-pressure clean airflow is used for multiple cleaning processes, including high-pressure airflow backflushing, rotary jetting, and mechanical knocking. After cleaning, the dust is filtered again. The dust filtration and cleaning cycles are repeated. 2. After the fan starts, it draws air from the cleanroom, making the air pressure in the dust chamber higher than that in the cleanroom. This causes the dust-laden air to enter the dust chamber through the air inlet. After being filtered by the filter element, the clean air enters the cleanroom and the air collection hood. The filtered air then enters the air tank through the air outlet, three-way valve, and one-way valve to store high-pressure air. 3. When the filter element is not clogged, the airflow pushes the push plate to compress the spring, and the airflow also pushes the I-beam frame. The pressure inside the air tank is less than the airflow pressure, so the high-pressure air inside the air tank cannot enter the rotating box. When the filter element is clogged, the airflow through the filter element decreases, the push plate resets under the action of the spring, and at the same time, one end of the I-beam frame approaches atmospheric pressure. The high-pressure air inside the air tank of the I-beam frame pushes the I-beam frame to move, and the high-pressure air enters the rotating box. 4. High-pressure airflow is ejected through the nozzle, which is tangent to the outer circumferential wall of the rotating box. When the high-pressure air is ejected, it drives the rotating box to rotate. The high-pressure air causes the filter element to expand and shake off surface dust. The rotating nozzle further blows and removes dust from the filter element. When the rotating box drives the rotating cover to rotate, it drives the striking rod to repeatedly strike the inner wall of the filter element. Through high-pressure airflow back-blowing, rotating spraying, and mechanical striking, the dust removal is more thorough, especially effective in removing dust accumulated inside the filter element and in hard-to-reach corners, thus extending the service life of the filter element.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] Example 1, as Figures 1-5 As shown, this solution proposes a dust collection device for indoor decoration, including a dust collection cylinder 1, which is hollow. A collecting hood 2 is fixedly connected to the top wall of the dust collection cylinder 1, and a fan is rotatably connected inside the collecting hood 2. A dust hopper 4 is fixedly connected to the lower inner wall of the dust collection cylinder 1, and an air chamber 3 is fixedly connected to the outer circumferential wall of the dust collection cylinder 1. The top of the collecting hood 2 is connected to the input end of the air chamber 3. A partition plate 6 is fixedly connected to the inner wall of the dust collection cylinder 1, dividing the internal space of the dust collection cylinder 1 into a dust-free chamber 11 and a dust chamber 12. The dust-free chamber 11 is connected to the collecting hood 2. Air inlets 13 are arranged in a circular array on the dust collection cylinder 1. The dust chamber 12 is connected to the outside air through the air inlet 13. A filter element 5 is connected between the bottom wall of the partition plate 6 and the top wall of the dust hopper 4. The filter element 5 is located inside the dust chamber 12. A push plate 7 is connected to the top wall of the dust collector 1. A rotating box 8 is rotatably connected to the bottom wall of the push plate 7. The rotating box 8 is hollow. The top wall of the push plate 7 is connected to the output end of the air bag 3. When the fan in the air collecting hood 2 is started, it draws air from the dust-free chamber 11. The air, carrying dust, enters the dust chamber 12 through the air inlet 13. The dust is filtered by the filter element 5. The filtered air drives the push plate 7 to move, and the air enters the dust-free chamber 11 and then enters the air collecting hood 2.

[0018] like Figures 1-3As shown, the top wall of the push plate 7 is symmetrically and fixedly connected to the top wall of the dust collector 1 with push springs 71. The outer edge of the bottom wall of the push plate 7 is set with an inclined edge. The top wall of the partition plate 6 is coaxially and fixedly connected with a contact ring 62. The outer edge of one side of the top wall of the contact ring 62 is set with an inclined edge. The outer edge of the bottom wall of the push plate 7 and the outer edge of the top wall of the contact ring 62 are matched. A through hole 72 is coaxially connected to the push plate 7. The through hole 72 is connected to the output end of the air bag 3 through an air pipe. When the fan in the air collecting hood 2 is not started, the push spring 71 is not compressed, and the push plate 7 is driven to contact the contact ring 62. The push plate 7 blocks the dust-free chamber 11 and the filter element 5. When the fan in the air collecting hood 2 is started, the filtered dust flows to the dust-free chamber 11 through the filter element 5. The airflow drives the push plate 7 to move and compresses the push spring 71. When the filter element 5 is blocked, the airflow through the filter element 5 is reduced, the push spring 71 is reset, and the push plate 7 is driven to contact the contact ring 62.

[0019] like Figures 1-4 As shown, nozzles 81 are fixedly connected in a ring array on the outer circumferential wall of the rotating box 8. The nozzles 81 are tangential to the outer circumferential wall of the rotating box 8. The top wall of the rotating box 8 is coaxially connected to the air inlet 86 and the connecting hole 72. The bottom wall of the rotating box 8 is coaxially fixedly connected to the rotating cover 85. The bottom wall of the rotating box 8 and the top wall of the rotating cover 85 are longitudinally slidably connected to the I-beam frame 83. The bottom end of the I-beam frame 83 contacts the inner top wall of the rotating cover 85, and the top end of the I-beam frame 83 contacts the inner top wall of the rotating box 8. A driving spring 84 is sleeved in the middle of the I-beam frame 83. The two ends of the driving spring 84 are fixedly connected to the top end of the I-beam frame 83 and the inner bottom wall of the rotating box 8, respectively. When the driving spring 84 is in the initial state, the driving spring 84 drives the top end of the I-beam frame 83 to contact the inner top wall of the rotating box 8. When the filter element 5 is not blocked, the filtered dust passes through the filter element 5. The airflow flows into the cleanroom 11, causing the push plate 7 to move. The airflow also pushes the top of the I-beam frame 83 to contact the bottom wall of the rotating box 8. The top of the I-beam frame 83 blocks the air inlet 86, preventing the air in the air tank 3 from entering the rotating box 8 through the connecting hole 72 and the air inlet 86. When the filter element 5 is blocked, the airflow through the filter element 5 decreases, and the push plate 7 contacts the contact ring 62. The push plate 7 drives the rotating box 8 to move into the interior of the filter element 5. At this time, the air in the air tank 3 drives the I-beam frame 83 to move, compressing and driving the spring 84. The high-pressure air in the air tank 3 enters the rotating box 8 through the connecting hole 72 and the air inlet 86. It is sprayed out through the nozzle 81 while driving the rotating box 8 to rotate. The high-pressure air expands the filter element 5, shaking off the dust on the surface of the filter element 5. At the same time, the rotating box 8 drives the nozzle 81 to rotate, rotating and blowing the filter element 5. The fallen dust enters the dust hopper 4.

[0020] like Figures 1-3 and Figure 5As shown, a striking rod 851 is slidably connected in a circular array on the rotating cover 85. One end of the striking rod 851 extends out of the rotating cover 85, and a striking spring 852 is sleeved on the other end of the striking rod 851. The two ends of the striking spring 852 are fixedly connected to the other end of the striking rod 851 and the inner circumferential wall of the rotating cover 85, respectively. A guide block 61 is fixedly connected in a circular array on the bottom wall of the partition plate 6. The guide block 61 is located inside the filter element 5 and is arc-shaped. The guide block 61 is positioned for striking... On the rotation path of rod 851, when the rotating box 8 drives the rotating cover 85 to rotate, the rotating cover 85 drives the striking rod 851 to rotate. The striking rod 851 contacts the guide block 61, compressing the striking rod 851 to move on the rotating cover 85, stretching the striking spring 852. When the striking rod 851 moves away from the guide block 61, the striking spring 852 returns to its original position, causing the striking rod 851 to contact the inner wall of the filter element 5. Together with the high-pressure airflow blown out by the rotation, the dust on the surface of the filter element 5 is removed, and the dust inside the filter element 5 is also removed.

[0021] like Figures 1-2 As shown, the top wall of the air collecting hood 2 is fixedly connected to an air outlet pipe 21. The other end of the air outlet pipe 21 is fixedly connected to a three-way valve 22. The other two ends of the three-way valve 22 are respectively fixedly connected to a one-way valve 23 and a pressure valve 24. The one-way valve 23 is connected to the input end of the air chamber 3 through an air pipe. When the fan in the air collecting hood 2 draws the filtered air into the air outlet pipe 21, the air flows through the three-way valve 22 to the one-way valve 23 and the pressure valve 24. At this time, the air pressure does not reach the value of the pressure valve 24. The air enters the air chamber 3 through the one-way valve 23. As the air pressure in the air chamber 3 increases, the air pressure entering the one-way valve 23 gradually increases. When the pressurized air pressure is greater than the pressure value of the pressure valve 24, the air in the air outlet pipe 21 is discharged through the pressure valve 24.

[0022] like Figures 1-2 As shown, the bottom end of the ash hopper 4 is coaxially and fixedly connected to an ash discharge valve, the model of which is Z644TC.

[0023] During interior decoration, the device is placed indoors. The fan inside the air collection hood 2 is activated to draw air from the cleanroom 11. The air pressure in the cleanroom 11 is lower than the air pressure in the dust chamber 12. The air pressure in the dust chamber 12 drives the push plate 7 away from the contact ring 62, compressing the push spring 71. The air carrying dust enters the dust chamber 12 through the air inlet 13 on the dust collector 1. After the dust is filtered by the filter element 5, the filtered air drives the push plate 7 away from the contact ring 62, compressing the push spring 71. The air enters the cleanroom 11, then enters the air collection hood 2 and the air outlet duct 21. The air flows through the three-way valve 22 to the one-way valve 23 and the pressure valve 24. At this time, the air pressure has not reached the value of the pressure valve 24. The air enters the air tank 3 through the one-way valve 23. As the air pressure in the air tank 3 increases, the air pressure entering the one-way valve 23 gradually increases. When the pressurized air pressure is greater than the pressure value of the pressure valve 24, the air in the air outlet duct 21 is discharged through the pressure valve 24. When the filter element 5 is not blocked, the airflow after filtering the dust flows through the filter element 5 to the dust-free chamber 11. The airflow drives the push plate 7 to move, compresses the push spring 71, and the airflow also pushes the other end of the I-beam frame 83 to contact the bottom wall inside the rotating box 8. The air in the air bag 3 cannot enter the rotating box 8 through the connecting hole 72 and the air inlet 86. When filter element 5 becomes clogged, the airflow through it decreases. This causes spring 71 to move push plate 7 into contact with contact ring 62. Push plate 7 blocks the dust-free chamber 11 from the filter element 5. Push plate 7 then moves rotating box 8 into the interior of filter element 5, causing the pressure inside filter element 5 to approach atmospheric pressure. The high-pressure air in air tank 3 moves I-beam frame 83, compressing and driving spring 84. The compressed air then enters rotating box 8 through connecting hole 72 and air inlet 86, and is sprayed out through nozzle 81, simultaneously rotating rotating box 8. The high-pressure air expands filter element 5, shaking off dust from its surface. The rotating box 8 drives the nozzle 81 to rotate, which in turn blows the filter element 5. The rotating box 8 also drives the rotating cover 85 to rotate, which in turn drives the striking rod 851 to rotate. The striking rod 851 contacts the guide block 61, compressing the striking rod 851 as it moves on the rotating cover 85, stretching the striking spring 852. When the striking rod 851 moves away from the guide block 61, the striking spring 852 returns to its original position, causing the striking rod 851 to contact the inner wall of the filter element 5. Combined with the high-pressure airflow blown out by the rotation, the dust on the surface of the filter element 5 is removed, and the dust falling off the filter element 5 enters the dust hopper 4. When the high-pressure airflow in the air tank 3 is released and the dust on the filter element 5 is cleaned, the fan in the air collecting hood 2 continues to draw air from the dust-free chamber 11. The air pressure in the dust-free chamber 11 is lower than the air pressure in the dust chamber 12. The air pressure in the dust chamber 12 drives the push plate 7 away from the contact ring 62, compressing the push spring 71. The air carrying dust enters the dust chamber 12 through the air inlet 13 on the dust collector 1. The dust is filtered by the filter element 5, and the dust is filtered again. The filtered air is stored. The dust cleaning and filtration process is repeated. When the dust in the ash hopper 4 needs to be discharged, the fan in the air collecting hood 2 stops, and the ash discharge valve at the bottom of the ash hopper 4 opens to discharge the dust in the ash hopper 4.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
