Description

Technical Field

[0001] This utility model relates to the field of dust recovery and treatment technology, and more specifically, to a dust recovery device for the feeding port of a storage device. Background Technology

[0002] Many mixing tanks or storage tanks have a feed inlet at the top, which also serves as a pressure relief / vent. When material is fed into the tank through the feed inlet, a large amount of air is expelled from it. This air carries small particles out of the feed inlet, creating dust. This dust can affect both the production environment and the health of workers.

[0003] To address the aforementioned issue (i.e., to recover dust without hindering workers from feeding material through the inlet), existing technologies typically install a cover at the inlet. One side of the cover has a window communicating with the inlet, and a dust collection pipe is installed on the top of the cover, with the other end connected to the recycling equipment. This allows dust generated at the inlet during feeding to pass through the cover into the dust collection pipe and then be sucked into the recycling equipment. However, existing recycling equipment still suffers from unsatisfactory recycling efficiency. Utility Model Content

Filter screens are disposed on the side walls and bottom of the filter chamber. The filter chamber and the second exhaust chamber are both connected to the first exhaust chamber. Dust in the dust discharge pipe can flow into the exhaust pipe sequentially through the air inlet pipe, the air inlet chamber, the filter chamber, the second exhaust chamber, and the first exhaust chamber.

[0008] Furthermore, in this invention, a valve is provided above the filter chamber, which can automatically adjust the opening degree according to the airflow size.

[0010] Furthermore, in this utility model, the linkage mechanism includes a circular slide plate that is slidably connected to the vertical rod. A plurality of rotating shafts are rotatably arranged on the outer periphery of the box body. The plurality of rotating shafts correspond one-to-one with the plurality of the guide vanes. The head end of any of the rotating shafts is connected to the corresponding guide vane, and its tail end is connected to the circular slide plate through a linkage mechanism.

[0011] Furthermore, in this utility model, any of the above-mentioned linkage mechanisms includes a connecting rod disposed at the tail end of the above-mentioned rotating shaft, the central axis of the connecting rod being parallel to and not collinear with the central axis of the above-mentioned rotating shaft; the outer periphery of the above-mentioned circular slide plate is provided with a plurality of sliding grooves corresponding one-to-one with the plurality of the above-mentioned connecting rods, the plurality of the above-mentioned sliding grooves being distributed in a circular array around the central axis of the above-mentioned air intake cavity, and the ends of the plurality of the above-mentioned connecting rods away from the above-mentioned rotating shaft being slidably connected to the corresponding sliding grooves respectively.

[0012] Furthermore, in this utility model, a conical air guide is provided on the top of the box body.

[0016] The beneficial effects of this utility model are:

[0017] 1. By installing a dust cover at the feed inlet and opening a feeding window on one side of the dust cover, dust can be drawn into the dust exhaust pipe through the dust cover without affecting the workers' feeding through the feed inlet.

[0018] 2. By installing a valve in the filter box that can automatically adjust the opening degree according to the airflow size, the more dust enters the air intake chamber, the greater the force of the airflow on several guide vanes will be. The airflow forces each guide vane to rotate, and the opening between two adjacent guide vanes will be greater. At this time, more dust will enter the filter chamber.

[0019] 3. By installing several filter plates inside the filter box, which work in conjunction with several guide vanes, the dust entering the filter chamber flows in a spiral shape. Firstly, this increases the residence time of the dust in the filter chamber; secondly, the filter plates intercept large particles of impurities in the dust, preventing them from directly impacting the side and bottom filter screens, thereby increasing their service life; and thirdly, it allows some of the dust to flow to the side filter screens for filtration, thus reducing the filtration burden on the bottom filter screen.

Detailed Implementation

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please see Figures 1-7 This utility model provides a technical solution:

[0030] A dust recovery device for the feeding port of a storage device is installed on one side of a tank 1. The top of the tank 1 has a feeding port 2 that communicates with its interior. A dust cover 3 is installed on the tank 1 to cover the feeding port 2. A feeding window 4 is provided on one side of the dust cover 3. The dust cover 3 is connected to a dust discharge pipe 5, and the end of the dust discharge pipe 5 away from the dust cover 3 is connected to the recovery device 6. The recovery device 6 can intercept solid particles in the dust within itself. An air pump (not shown in the figure) is also installed on the dust discharge pipe 5 to draw the dust from inside the dust cover 3 into the dust discharge pipe 5, and then discharge it into the recovery device 6.

[0031] Specifically, in this embodiment, the recycling device 6 includes an outer casing 601 and a filter box 602 installed inside the outer casing 601. The outer diameter of the filter box 602 is smaller than the inner diameter of the outer casing 601. During installation, a gap must exist between the outer side wall of the filter box 602 and the inner side wall of the outer casing 601. This gap forms the space of the first exhaust chamber 8. An exhaust pipe 9 communicating with the first exhaust chamber 8 is installed on the top of the outer casing 601. Inside the filter box 602, from top to bottom, are an air inlet chamber 701, a filter chamber 702, and a second exhaust chamber 703. An air inlet pipe 10 communicating with the air inlet chamber 701 is installed on the top of the filter box 602. Filter screens for filtering dust are installed on the side walls and bottom of the filter chamber 702. Both the filter chamber 702 and the second exhaust chamber 703 are connected to the first exhaust chamber 8. Dust in the dust discharge pipe 5 can flow into the exhaust pipe 9 in sequence through the air inlet pipe 10, air inlet chamber 701, filter chamber 702, second exhaust chamber 703 and first exhaust chamber 8.

[0032] In this embodiment, a valve that can automatically adjust its opening degree according to the airflow size is also installed above the filter chamber 702.

[0033] Specifically, refer to Figure 4 To install the aforementioned valve, a vertical rod 11 is installed inside the filter box 602 in this embodiment, with the central axis of the vertical rod 11 collinear with the central axis of the filter box 602. A cylindrical, hollow box 12 is installed at the top of the vertical rod 11, located within the air intake chamber 701. The valve includes several guide vanes 1301 rotatably connected to the box 12. Each guide vane 1301 has a helical structure, and the guide vanes 1301 are arranged in a circular array around the central axis of the air intake chamber 701. A linkage mechanism is also installed inside the box 12, and each guide vane 1301 is connected to the linkage mechanism. The linkage mechanism allows the guide vanes 1301 to rotate synchronously when the air pressure in the air intake chamber 701 changes, thus changing the opening between adjacent guide vanes 1301.

[0034] Reference Figures 4-6 In this embodiment, the linkage mechanism includes a cylindrical sliding plate 1302 that can slide up and down on the vertical rod 11. In the balanced state, the cylindrical sliding plate 1302 is located inside the box 12. Several rotating shafts 1303 are rotatably mounted on the outer periphery of the box 12. Each rotating shaft 1303 corresponds to a number of guide vanes 1301. The head end of any rotating shaft 1303 is connected to the corresponding guide vane 1301, and its tail end extends into the box 12. The tail end of each rotating shaft 1303 is connected to the cylindrical sliding plate 1302 through a linkage mechanism.

[0035] In this embodiment, the linkage mechanism is a connecting rod 1304, which is installed at the tail end of the rotating shaft 1303. During installation, the central axis of the connecting rod 1304 must be parallel and not collinear with the central axis of the rotating shaft 1303. The outer periphery of the circular sliding plate 1302 is provided with several sliding grooves 1305 corresponding one-to-one with the connecting rods 1304. The sliding grooves 1305 are arranged in a circular array around the central axis of the air intake chamber 701. The ends of the connecting rods 1304 furthest from the rotating shaft 1303 are slidably connected to their respective sliding grooves 1305. Figure 7 From this perspective, the extension direction of the slide groove 1305 in this embodiment is horizontal (i.e., the horizontal direction). In other embodiments of this embodiment, the extension direction of the slide groove 1305 may also be vertical (i.e., the vertical direction). In this embodiment, the number of guide vanes 1301 is eight, and correspondingly, the number of rotating shafts 1303, connecting rods 1304, and slide grooves 1305 are all eight. In other embodiments of this embodiment, the number of the above-mentioned parts can be increased or decreased according to the actual situation.

[0036] from Figure 7 From the perspective of the dust, when one of the guide vanes 1301 is subjected to the downward impact force of the dust, the current guide vane 1301 rotates, and the corresponding connecting rod 1304 will rotate around the central axis of the corresponding rotating shaft 1303. This action will drive the circular slide plate 1302 to move upward. The upward movement of the circular slide plate 1302 will drive the other connecting rods 1304 to rotate around the central axis of the corresponding rotating shaft 1303, thereby causing the other guide vanes 1301 to rotate.

[0037] Reference Figure 4 and Figure 7 When dust (i.e., dust-laden gas) with a certain flow velocity flows into the intake chamber 701 through the intake pipe 10, in order to ensure that the dust entering the intake chamber 701 is evenly blown towards each guide vane 1301, a conical guide hood 14 is also installed on the top of the box body 12 in this embodiment. The central axis of the conical guide hood 14, the central axis of the intake pipe 10, and the central axis of the box body 12 are all collinear with the central axis of the intake chamber 701, and the guide slope of the conical guide hood 14 faces several guide vanes 1301. In this way, the conical guide hood 14 can guide the dust entering the intake chamber 701. In other embodiments of this embodiment, several guide grooves can also be opened on the conical outer surface of the conical guide hood 14, and the several guide grooves correspond one-to-one with several guide vanes 1301, that is, each guide groove extends towards the corresponding guide vane 1301, which can also further play a guiding role.

[0038] Reference Figure 4In this embodiment, the filter screen includes a side filter screen 1501 and a bottom filter screen 1502. The side filter screen 1501 is configured as the side of the filter chamber 702, and the bottom filter screen 1502 is configured as the bottom of the filter chamber 702 (and the bottom filter screen 1502 is also the top of the second exhaust chamber 703). A plurality of exhaust ports 17 are provided on the side wall of the filter box 602. Any exhaust port 17 in the vertical direction is located below the bottom filter screen 1502, and any exhaust port 17 connects to the first exhaust chamber 8 and the second exhaust chamber 703. In this embodiment, the bottom filter screen 1502 is designed as a conical structure, with a large-diameter end at the top and a small-diameter end at the bottom. The top of the bottom filter screen 1502 is connected to the top of the second exhaust chamber 703.

[0039] Reference Figure 4 When dust from the intake chamber 701 flows into the filter chamber 702 through the valve, in order to intercept large particles of impurities in the dust and prevent them from directly impacting the side filter screen 1501, thereby increasing the service life of the side filter screen 1501, this embodiment specifically installs eight filter plates 16 on the side filter screen 1501. All eight filter plates 16 are located within the filter chamber 702, and are arranged in a circular array around the central axis of the intake chamber 701. Thus, when dust from the intake chamber 701 flows into the filter chamber 702 through the valve, large particles of impurities in the dust are first intercepted by the filter plates 16, and then fall onto the bottom filter screen 1502. Large particles of impurities will not directly impact the side filter screen 1501, thereby increasing its service life. Other solid particles in the dust, after being intercepted by the side filter screen 1501 and the bottom filter screen 1502, enter the first exhaust chamber 8 and the second exhaust chamber 703 respectively, and are then discharged through the exhaust pipe 9. In this way, solid particles in the dust are intercepted in the filter chamber 702.

[0040] However, the above design has a problem: if too many large particles of impurities accumulate on the filter plate 16, it will affect the gas passage efficiency of the filter plate 16. Therefore, to solve this problem, in this embodiment, all eight filter plates 16 are designed as spiral structures, and the spiral direction of any filter plate 16 is opposite to the spiral direction of the guide vane 1301. (Refer to...) Figure 4 and Figure 7 When the valve is opened, the dust guided by the guide vanes 1301 is first blown toward the filter plate 16, and then toward the side filter screen 1501. Large particles intercepted by the filter plate 16 fall onto the bottom filter screen 1502. Because the bottom filter screen 1502 has a conical structure, the large particles accumulated on the bottom filter screen 1502 will not affect the filtration effect of the bottom filter screen 1502.

[0041] In the above structural design, the side filter 1501 plays the main filtering role. The solid particles filtered in the dust are retained in the filter chamber 702 (mainly accumulating on the bottom filter 1502), and can be recycled periodically.

[0042] Working principle:

[0043] If there are no valves and filter plates 16 inside the filter box 602, the dust entering the filter box 602 will flow directly from top to bottom to the bottom filter screen 1502. In this case, the bottom filter screen 1502 plays the main filtering role. However, in this case, the dust flows in a straight line, and the residence time of the dust in the filter box 602 is relatively short. At the same time, large particles of impurities in the dust will directly impact the bottom filter screen 1502, which will affect the service life of the bottom filter screen 1502.

[0044] Therefore, by installing a valve in the filter box 602 that automatically adjusts its opening degree according to the airflow size, the greater the amount of dust entering the intake chamber 701, the greater the force of the airflow on the guide vanes 1301. The airflow forces each guide vane 1301 to rotate, and the opening between two adjacent guide vanes 1301 becomes larger, resulting in more dust entering the filter chamber 702. By installing several filter plates 16 in the filter box 602, which work in conjunction with the guide vanes 1301, the dust entering the filter chamber 702 flows in a spiral shape. Firstly, this increases the residence time of dust in the filter chamber 702; secondly, the filter plates 16 first intercept large particles of impurities in the dust, preventing them from directly impacting the side filter screen 1501 and the bottom filter screen 1502, thereby increasing the service life of the two filters; and thirdly, it allows some dust to flow to the side filter screen 1501 for filtration, thus reducing the filtration burden on the bottom filter screen 1502.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
