Description

Technical Field

[0001] This utility model belongs to the field of industrial dust removal technology, specifically relating to a porous micro powder centralized collection device for dust collectors. Background Technology

[0002] In industries such as metallurgy, chemicals, building materials, and food, large amounts of fine dust are typically generated during production, requiring collection and treatment through networked dust collectors. To centrally transport dust collected from multiple dust collectors to one location for storage or further processing, a centralized collection system based on a screw conveyor is commonly used.

[0003] During the process of expanding perlite, it is necessary to collect impurities and dust filtered by multiple filtration systems. However, the discharge ports above the casing of the existing high-level screw conveyor are usually in a normally open state. When some of the corresponding dust collectors stop working, their discharge ports become airflow short-circuit channels. The negative pressure in the screw conveyor cavity will draw air back through these open ports, seriously interfering with the normal discharge of other working dust collectors. This makes it difficult for dust to fall in smoothly, and it may even be carried away by the airflow, causing secondary dust and reducing the overall collection efficiency. Moreover, impurities and dust in the screw conveyor can easily cause jamming and interference, which will not only increase the operating power consumption of the screw conveyor, but also reduce the reliability of the system and make it difficult to operate stably for a long time. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a porous micro-powder centralized collection device for dust collectors. This device can monitor the dust status of each feed pipe in real time and dynamically adjust the flow status of each feed gate mechanism to prevent backflow from interfering with the feed inlets of other working dust collection units, thus eliminating secondary dust re-entrainment and ensuring stable and efficient collection efficiency of the entire system. It also reduces the operating resistance of the auger, thereby reducing the power consumption of the drive motor, achieving energy-saving operation, reducing equipment wear, and further ensuring the efficient and reliable operation of the overall system.

Airlocks are fixedly installed between the outlet end of the first micro-powder collecting pipe and the inlet end of the second micro-powder collecting pipe, as well as at the outlet end of the second micro-powder collecting pipe.

[0006] Preferably, the feeding gate mechanism includes a feeding pipe, a rotating gate, a bevel gear rod, a gate drive motor, and a dust sensor. The feeding pipe is connected to the top of the feeding inlet. There are several rotating gates, which are equidistantly rotatably connected inside the feeding pipe. Each rotating gate has a bevel gear fixedly connected to the same side. The bevel gear rod is fixedly provided with bevel gears of the same number as the rotating gates and meshing one-to-one. The rotation shaft of the bevel gear rod is connected to the output end of the gate drive motor. The dust sensor is fixedly installed on the inner wall of the feeding pipe.

[0007] Preferably, the two adjacent bevel gears on the bevel gear rod are symmetrically arranged with the center between them as the axis of symmetry, so that when the gate drive motor drives the bevel gear rod to rotate, it can drive the two adjacent rotating gates to rotate in opposite directions.

[0008] Preferably, the spiral conveying mechanism includes a drive motor and a spiral auger. The spiral auger is connected to the output shaft of the drive motor via a spline. The two spiral augers in the two spiral conveying mechanisms are respectively rotatably connected inside the first micro powder collecting pipe and the second micro powder collecting pipe. The two drive motors are respectively fixedly installed on the side of the first micro powder collecting pipe and the second micro powder collecting pipe away from the discharge end.

[0009] Preferably, the top of the first and second micro powder collecting pipes is provided with multiple feed inlets, and each feed inlet is equipped with an independent feed gate mechanism.

[0010] Preferably, the outlets of the first and second micro powder collecting pipes are both located at the bottom, away from their respective drive motors, and the installation height of the second micro powder collecting pipe is lower than that of the first micro powder collecting pipe.

[0011] The beneficial effects of the above technical solution are as follows:

Detailed Implementation

[0018] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 4 The embodiments are described in detail below.

[0019] This embodiment provides a porous micro-powder centralized collection device for a dust collector, as shown in the attached figure. Figure 1-4As shown, it includes a first micro powder collecting pipe 1, a second micro powder collecting pipe 2, and a screw conveying mechanism 3. Both the first micro powder collecting pipe 1 and the second micro powder collecting pipe 2 are equipped with a screw conveying mechanism 3. The screw conveying mechanism 3 includes a drive motor 301 and a screw auger 302. The screw auger 302 is connected to the output end of the drive motor 301 by a spline. The two screw augers 302 in the two screw conveying mechanisms 3 are respectively horizontally inserted into the first micro powder collecting pipe 1 and the second micro powder collecting pipe 2. The two drive motors 301 are respectively fixedly installed on the same side of the first micro powder collecting pipe 1 and the second micro powder collecting pipe 2.

[0020] The feed end of the second micro powder collecting pipe 2 is connected to the discharge end of the first micro powder collecting pipe 1, and the height of the second micro powder collecting pipe 2 is lower than that of the first micro powder collecting pipe 1, which can ensure that the dust of the first micro powder collecting pipe 1 falls from the outlet end into the second micro powder collecting pipe 2 under the conveying of the screw conveyor mechanism 3.

[0021] The first micro-powder collecting pipe 1 and the second micro-powder collecting pipe 2 are both provided with a feed inlet 4 at their tops, and a feed gate mechanism 5 is provided at the top of the feed inlet 4 to control the opening and closing of the feed inlet 4. The feed gate mechanism 5 includes a feed pipe 501, a rotating gate 502, a bevel gear rod 503, a gate drive motor 504, and a dust sensor 505. The feed pipe 501 is connected to the top of the feed inlet 4, and its top is connected to the outlet end of the external dust removal mechanism. There are several rotating gates 502, and the several rotating gates 502 are equidistantly rotatably connected inside the feed pipe 501. Each rotating gate 502 has a bevel gear fixedly connected to the same side, and all the bevel gears are drivenly connected to the bevel gear rod 503. The multiple bevel gears provided outside the bevel gear rod 503 are symmetrically arranged with each other, and adjacent bevel gears are symmetrically arranged with the center of their axes as the axis of symmetry. The number of bevel gears outside the bevel gear rod 503 is related to the rotating gate 502. The number of 02 is the same. The bevel gear on the side of each rotating gate 502 meshes with the bevel gear on the bevel gear rod 503. The rotating shaft of the bevel gear rod 503 is connected to the output end of the gate drive motor 504 through a spline. A protective cover 9 is sleeved on the outside of the bevel gear rod 503 and the protective cover 9 is fixedly connected to the side of the feed pipe 501. The bevel gear rod 503 is horizontally rotatably connected inside the protective cover 9. The gate drive motor 504 is fixedly installed on the side of the protective cover 9. When the gate drive motor 504 drives the bevel gear rod 503 to rotate, it can drive the rotating gate 502 to rotate through the bevel gear. The rotation directions of two adjacent rotating gates 502 are opposite, so the opening and closing state between each rotating gate 502 can be adjusted. When all rotating gates 502 are rotated to the horizontal state, the feed pipe 501 can be blocked. When all rotating gates 502 are rotated to the vertical state, the feed pipe 501 is in a fully open state.

[0022] Multiple dust sensors 505 are equidistantly fixed on the top of the inner wall of the feed pipe 501. The dust sensors 505 can monitor the dust situation at the corresponding feed pipe 501 in real time, and can dynamically adjust the feed gate mechanism 5 according to whether dust falls at each feed port 4. This can effectively reduce airflow interference. After closing the rotating gate 502 of the idle feed pipe 501, it can effectively prevent the negative pressure airflow in the first micro powder collection pipe 1 or the second micro powder collection pipe 2 from being sucked back through the idle feed pipe 501, interfering with the efficiency of other working dust removal units, and also preventing the intake of external air. At the same time, it can also prevent dust from accumulating near the idle feed port 4 or affecting the discharge trajectory of other drop points, ensuring the normal conveying of dust in the first micro powder collection pipe 1 and the second micro powder collection pipe 2.

[0023] Multiple feed inlets 4 can be opened at the top of the first micro powder collecting pipe 1 and the second micro powder collecting pipe 2. Each feed inlet 4 is connected to the dust outlet of the external dust removal system through a feed gate mechanism 5. The multiple feed gate mechanisms 5 are independently controlled and can dynamically adjust the on / off state of the corresponding feed gate mechanism 5 according to the dust falling in each feed inlet 4. This can effectively reduce the interference to the micro powder collecting device and ensure efficient dust collection.

[0024] An inclined air inlet pipe 6 is fixedly connected to the top of the first micro powder collecting pipe 1 near the drive motor 301. A high-speed blower 7 is fixedly installed at the top of the inclined air inlet pipe 6. The inclined air inlet pipe 6 is connected to the interior of the first micro powder collecting pipe 1. The high-speed blower 7 can continuously introduce high-speed air into the interior of the first micro powder collecting pipe 1. After entering the first micro powder collecting pipe 1, the high-speed air will flow along the spiral path of the spiral auger 302, thereby accelerating the flow speed of dust in the first micro powder collecting pipe 1 and cleaning the dust adsorbed on the spiral auger 302. This can effectively reduce the weight of the spiral auger 302 and thus reduce power consumption. The high-speed air flows along the spiral auger 302 in the first micro powder collecting pipe 1 towards the outlet end and can enter the interior of the second micro powder collecting pipe 2 from the outlet end. This can also have the same effect on the interior of the second micro powder collecting pipe 2 as on the first micro powder collecting pipe 1, thereby improving the overall dust collection efficiency of the device.

[0025] The outlet ends of the first micro-powder collecting pipe 1 and the second micro-powder collecting pipe 2 are both located at the bottom, away from the drive motor 301. The outlet end of the first micro-powder collecting pipe 1 is connected to the inlet 4 of the second micro-powder collecting pipe 2, and an airlock 8 is fixedly installed between them. An airlock 8 is also fixedly installed at the outlet end of the second micro-powder collecting pipe 2. The airlock 8 can control and regulate the airflow. The airlock 8 at the outlet end of the first micro-powder collecting pipe 1 allows dust and gas in the first micro-powder collecting pipe 1 to enter the second micro-powder collecting pipe 2, without allowing dust and gas in the second micro-powder collecting pipe 2 to flow back into the first micro-powder collecting pipe 1. The airlock 8 at the outlet end of the second micro-powder collecting pipe 2 allows dust and gas in the second micro-powder collecting pipe 2 to be discharged to the outside, without allowing external gas to flow back into the second micro-powder collecting pipe 2. This ensures that the device as a whole can smoothly collect and process the dust and impurities discharged from each dust removal system, ensuring the smooth operation of the entire system.

[0026] The drive motor 301, the gate drive motor 504, the dust sensor 505, the high-speed blower 7, and the airlock 8 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0027] In summary, the operating steps of this porous micro-powder centralized collection device for dust collectors are as follows:

[0028] 1. Start the drive motor 301 in the first micro powder collection pipe 1 and the second micro powder collection pipe 2. The two spiral augers 302 start to rotate. At the same time, start the high-speed blower 7. The high-speed airflow is blown into the interior of the first micro powder collection pipe 1 through the inclined air inlet pipe 6.

[0029] 2. Dust generated by each dust removal system enters its corresponding feed pipe 501 through its respective pipeline. Dust sensors 505 installed on the inner wall of the feed pipe 501 monitor in real time whether dust is flowing through. When dust is detected and a large amount of dust continues to fall, the gate drive motor 504 drives the bevel gear rod 503 to rotate, causing all the rotating gates 502 to rotate to a vertical position, opening the feed channel and allowing dust to fall into the fine powder collection pipe below. When the dust sensor 505 detects that the dust flow has stopped, the gate drive... After receiving the signal, the motor 504 rotates in the opposite direction, driving all the rotating gates 502 to rotate to a horizontal state, completely closing the feed pipe 501 and sealing the feed port 4. When the amount of dust detected is small, the gate drive motor 504 can drive each rotating gate 502 to rotate to an inclined state, reducing the opening degree between each rotating gate 502, so that the dust can still fall from the gap of the rotating gate 502, and at the same time, the flow rate of the feed pipe 501 can be appropriately reduced, which reduces the backflow of dust to a certain extent.

[0030] 3. Dust falls into the first micro powder collection pipe 1 through the open feed port 4. The rotating spiral auger 302 conveys the dust forward. At the same time, the high-speed airflow injected from the inclined air inlet pipe 6 moves along the spiral direction of the spiral auger 302. On the one hand, it accelerates the conveying speed of the dust, and on the other hand, it blows the auger blades and pipe wall to prevent dust from adhering.

[0031] 4. The mixture of dust and airflow conveyed to the end of the first micro powder collection pipe 1 enters the feed end of the second micro powder collection pipe 2 through the airlock 8. The dust entering the second micro powder collection pipe 2 continues to move towards the outlet end under the conveying of the spiral auger 302 inside and the assistance of the high-speed airflow from upstream. Finally, all the dust is discharged to the final collection bin or treatment equipment through the airlock 8 at the discharge end of the second micro powder collection pipe 2.

[0032] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
