Description

Technical Field

[0001] This application relates to the field of dust removal devices, and more particularly to a dust removal device with an automatic cleaning structure. Background Technology

[0002] With the rapid development of society and economy, people's living standards and quality of life are constantly improving. In addition, the pace of life is accelerating, and both production and life have become more intelligent and automated. Moreover, the requirements for environmental quality are getting higher and higher, which has led to the emergence of dust removal devices. Dust removal devices refer to equipment that separates dust from the air.

[0003] The utility model patent with announcement number CN212327651U proposes a cyclone dust collector, including a first cylinder, a second cylinder, an overflow pipe, multi-layer spiral blades, a dust outlet, and a bag structure. An air inlet pipe is provided at the upper end of the first cylinder along its tangential direction. The second cylinder is embedded in the first cylinder and connected to the air inlet pipe, forming a first annular channel between the second cylinder and the first cylinder. The overflow pipe is embedded in the second cylinder and extends to the outside of the first cylinder, forming a second annular channel between the overflow pipe and the second cylinder. The multi-layer spiral blades are disposed within the second annular channel and sleeved on the overflow pipe. The dust outlet is located at the upper end of the second cylinder, and the second annular channel communicates with the first annular channel through the dust outlet. The bag structure is connected to the lower end of the overflow pipe.

[0004] The aforementioned cyclone dust collector needs to be shut down when the dust in the ash hopper reaches a certain height for cleaning, in order to prevent air leakage at the bottom, which reduces the efficiency of the work. Utility Model Content

[0005] To achieve the above objectives, this application provides a dust removal device with an automatic cleaning structure.

[0006] The dust removal device with an automatic cleaning structure provided in this application adopts the following technical solution:

[0007] A dust removal device with an automatic cleaning structure includes a housing and a cyclone dust collector. A dust collection hopper is installed at the bottom of the cyclone dust collector. The dust collection hopper is provided with a discharge assembly for discharging dust from the dust collection hopper. The discharge assembly includes an electric push rod installed on one side wall of the dust collection hopper. A connecting rod is fixedly connected to the output end of the electric push rod. A push-pull rod is fixedly connected to the upper surface of the end of the connecting rod away from the electric push rod. A sealing column is fixedly connected to the top of the push-pull rod. The end of the sealing column away from the push-pull rod passes through the dust collection hopper and is located at the bottom of the cyclone dust collector.

[0008] By adopting the above technical solution, during operation, the electric push rod is activated, causing the push-pull rod to lower the sealing column, positioning the top of the sealing column inside the ash hopper. This connects the ash hopper to the cyclone dust collector. Then, dust-laden gas is sent into the cyclone dust collector, allowing the dust to enter the ash hopper. Afterward, the electric push rod is activated again, raising the sealing column and moving its top into the cyclone dust collector, sealing the cyclone dust collector and ash hopper. The sealing column is then pushed further until its bottom is inside the ash hopper, discharging the dust from the bottom. This minimizes the need to stop the cyclone dust collector when the dust in the ash hopper reaches a certain height for cleaning, thus avoiding reduced work efficiency.

[0009] Preferably, the bottom of the ash storage hopper and the top of the sealing column are both conical.

[0010] By adopting the above technical solution, the sealing column with a cone-shaped top can prevent dust from accumulating on the top of the sealing column, thus preventing the dust from being discharged from the ash storage hopper. At the same time, the bottom of the ash storage hopper is an inverted cone shape, which allows the dust to be concentrated and slid down for discharge.

[0011] Preferably, a rubber sealing ring is fitted onto the sealing post, and the upper surface of the rubber sealing ring is inclined.

[0012] By adopting the above technical solution, when the top of the sealing column is inside the ash hopper, the lower surface of the rubber sealing ring abuts against the bottom wall of the ash hopper, and when the top of the sealing column is inside the cyclone dust collector, the upper surface of the rubber sealing ring abuts against the top wall of the ash hopper. This can improve the sealing performance, prevent air leakage at the bottom of the cyclone dust collector, and avoid affecting the dust removal effect of the cyclone dust collector.

[0013] Preferably, a cross plate is fixedly connected to the lower surface of the connecting rod below the push-pull rod, and four vertically arranged guide rods are fixedly connected to the bottom of the ash storage hopper. The end of the guide rod away from the ash storage hopper passes through the four ends of the cross plate and forms a sliding connection.

[0014] By adopting the above technical solution, the stability of the sealing column's lifting and lowering can be improved through the cooperation of the cross plate and guide rod, preventing swaying.

[0015] Preferably, a fixed bracket is fixedly connected to one side wall of the housing, a dust extraction fan is installed on the upper surface of the fixed bracket, a dust extraction pipe is fixedly connected to the exhaust end of the dust extraction fan, the end of the exhaust pipe away from the dust extraction fan is located inside the housing, and a ventilation grille is installed on the other side wall of the housing.

[0016] By adopting the above technical solution, when the dust is discharged from the ash hopper, the dust extraction fan can be activated to extract the dust discharged into the shell, clean the inside of the shell, and prevent the dust from accumulating inside the shell.

[0017] Preferably, both the inlet and outlet ends of the cyclone dust collector are fixedly connected to flanges.

[0018] By adopting the above technical solution, the pipeline can be conveniently connected to the inlet and outlet of the cyclone dust collector via flanges.

[0019] Preferably, a touch switch is fixedly connected to the lower surface of the ash hopper, the touch switch is electrically connected to the dust extraction fan, and a touch block is fixedly connected to one side wall of the connecting rod, the touch block being located directly below the touch switch.

[0020] By adopting the above technical solution, when the connecting rod drives the push-pull rod to rise and fall, the contact block comes into contact with the touch switch, which can automatically start the dust extraction fan to extract the dust inside the housing.

[0021] Preferably, a level sensor for detecting the dust content inside the ash hopper is installed on one side of the top of the ash hopper, and the level sensor is electrically connected to the electric push rod.

[0022] By adopting the above technical solution and setting a material level sensor, when the dust in the ash hopper reaches the set height, the electric push rod is automatically activated, causing the sealing column to block the top of the ash hopper and discharge the dust. When the dust drops to the set height, the sealing column descends to seal the bottom of the ash hopper. At the same time, the contact block disengages from the contact switch, causing the dust extraction fan to turn off, thus achieving automatic cleaning.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes the coordinated structure of an electric push rod, a push-pull rod, and a sealing column. During operation, activating the electric push rod causes the push-pull rod to lower the sealing column, positioning its top within the ash hopper. This connects the ash hopper to the cyclone dust collector, allowing dust-laden gas to be fed into the cyclone dust collector, whereby the dust enters the ash hopper. The electric push rod is then activated again to raise the sealing column, moving its top into the cyclone dust collector to seal the cyclone dust collector and ash hopper. Continuing to push the sealing column further up, its bottom is positioned within the ash hopper, discharging the dust from the bottom. This design minimizes the need to shut down the cyclone dust collector when cleaning the ash hopper, thus reducing operational efficiency.

[0025] 2. By setting a material level sensor, when the dust in the ash hopper reaches the set height, the electric push rod is automatically activated, causing the sealing column to block the top of the ash hopper and open the bottom to discharge the dust. At the same time, the contact block contacts the touch switch, automatically starting the dust extraction fan to extract the dust from the casing. When the dust drops to the set height, the sealing column descends to seal the bottom of the ash hopper, and the contact block disengages from the touch switch, turning off the dust extraction fan, thus achieving automatic cleaning.

Detailed Implementation

[0031] The following is combined with Figure 1-Figure 4 This application will be described in further detail.

[0032] This application discloses a dust removal device with an automatic cleaning structure.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A dust removal device with an automatic cleaning structure includes a housing 1 and a cyclone dust collector 2. The cyclone dust collector 2 is installed inside the housing 1 and its inlet and outlet ends penetrate the housing 1. A dust collection hopper 3 is installed at the bottom of the cyclone dust collector 2. The dust collection hopper 3 is equipped with a discharge component for discharging dust from the dust collection hopper 3. The discharge component includes an electric push rod 4, a connecting rod 5, a push-pull rod 6, and a sealing column 7.

[0034] The electric push rod 4 is installed on one side wall of the ash hopper 3. The output end of the electric push rod 4 is fixedly connected to one end of the connecting rod 5. The upper surface of the end of the connecting rod 5 away from the electric push rod 4 is fixedly connected to one end of the push-pull rod 6. The sealing column 7 is fixedly connected to the top of the push-pull rod 6. The sealing column 7 is located below the ash hopper 3 and the end away from the push-pull rod 6 penetrates through the ash hopper 3 and is located at the bottom of the cyclone dust collector 2. The length of the sealing column 7 is greater than the height of the ash hopper 3 to prevent the bottom of the sealing column 7 from moving into the ash hopper 3 before the top of the sealing column 7 has sealed the top of the ash hopper 3, which would cause air leakage at the bottom of the cyclone dust collector 2.

[0035] Reference Figure 2 and Figure 4 The bottom of the ash hopper 3 and the top of the sealing column 7 are both conical. The conical top of the sealing column 7 can prevent dust from accumulating on the top of the sealing column 7 and preventing the dust from being discharged from the ash hopper 3. At the same time, the bottom of the ash hopper 3 is an inverted conical shape, which can make the dust fall down in a concentrated manner and improve the discharge efficiency.

[0036] Reference Figure 2 and Figure 4 A rubber sealing ring 8 is fitted on the sealing column 7. The upper surface of the rubber sealing ring 8 is inclined. When the top of the sealing column 7 is inside the ash hopper 3, the lower surface of the rubber sealing ring 8 abuts against the bottom wall of the ash hopper 3. When the top of the sealing column 7 is inside the cyclone dust collector 2, the upper surface of the rubber sealing ring 8 abuts against the top wall of the ash hopper 3. This can improve the sealing performance and prevent air leakage at the bottom of the cyclone dust collector 2, which would affect the dust removal effect of the cyclone dust collector 2.

[0037] Reference Figure 2 and Figure 4 A cross plate 9 is fixedly connected to the lower surface of the connecting rod 5 below the push-pull rod 6. Four vertically arranged guide rods 10 are fixedly connected to the bottom of the ash hopper 3. The end of the guide rod 10 away from the ash hopper 3 passes through the four ends of the cross plate 9 and forms a sliding connection. Through the cooperation of the cross plate 9 and the guide rods 10, the stability of the lifting and lowering of the sealing column 7 can be improved and the swaying can be prevented.

[0038] Reference Figure 2 A fixed bracket 11 is fixedly connected to one side wall of the housing 1. A dust extraction fan 12 is installed on the upper surface of the fixed bracket 11. A dust extraction pipe 13 is fixedly connected to the exhaust end of the dust extraction fan 12. The end of the exhaust pipe 13 away from the dust extraction fan 12 is located inside the housing 1. A ventilation grille 14 is installed on the other side wall of the housing 1. When dust is discharged from the dust storage hopper 3, the dust discharged into the housing 1 can be extracted by starting the dust extraction fan 12 to clean the inside of the housing 1 and prevent dust from accumulating inside the housing 1.

[0039] Reference Figure 2The inlet and outlet of the cyclone dust collector 2 are both fixedly connected with flanges 15, which facilitates the connection of pipelines to the inlet and outlet of the cyclone dust collector 2.

[0040] Reference Figure 3 A touch switch 16 is fixedly connected to the lower surface of the ash hopper 3. The touch switch 16 is electrically connected to the dust extraction fan 12. A touch block 17 is fixedly connected to one side wall of the connecting rod 5. The touch block 17 is located directly below the touch switch 16. When the connecting rod 5 drives the push-pull rod 6 to rise and fall, the touch block 17 contacts the touch switch 16, which can automatically start the dust extraction fan 12 to extract the dust in the housing 1.

[0041] Reference Figure 2 A level sensor 18 for detecting the dust content inside the ash hopper 3 is installed on one side of the top of the ash hopper 3. The level sensor 18 is electrically connected to the electric push rod 4. By setting the level sensor 18, when the dust in the ash hopper 3 reaches the set height, the electric push rod 4 is automatically activated, causing the sealing column 7 to block the top of the ash hopper 3 and open the bottom to allow the dust to be discharged. When the dust drops to the set height, the sealing column 7 is lowered to seal the bottom of the ash hopper 3. At the same time, the contact block 17 disengages from the contact switch 16, causing the dust extraction fan 12 to turn off, thus achieving automatic cleaning.

[0042] The implementation principle of a dust removal device with an automatic cleaning structure according to an embodiment of this application is as follows: In use, the user first positions the top of the sealing column 7 inside the ash hopper 3, connecting the ash hopper 3 to the cyclone dust collector 2. Then, gas carrying dust is sent into the cyclone dust collector 2, allowing the dust to enter the ash hopper 3. Next, by setting a level sensor 18, when the dust in the ash hopper 3 reaches a set height, the electric push rod 4 is activated, causing the push-pull rod 6 to lift the sealing column 7, positioning the top of the sealing column 7 at the bottom of the cyclone dust collector 2, blocking the top of the ash hopper 3. The column then continues to rise, moving the bottom of the sealing column 7 into the ash hopper 3, allowing the dust to be collected. The bottom of the ash hopper 3 opens to discharge dust, and at the same time, the contact block 17 contacts the contact switch 16 to control the start of the dust extraction fan 12 to extract dust from the housing 1. When the dust in the ash hopper 3 drops to a set height, the sealing column 7 descends, so that the top of the sealing column 7 is inside the ash hopper 3, sealing the bottom of the ash hopper 3. The top is connected to the cyclone dust collector 2 to continue storing dust. At the same time, the contact block 17 disengages from the contact switch 16, causing the dust extraction fan 12 to turn off, realizing automatic cleaning. This avoids the problem of the cyclone dust collector 2 needing to stop when the dust in the ash hopper 3 reaches a certain height for cleaning, which would reduce work efficiency.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
