Description

Technical Field

[0001] This utility model belongs to the field of dust collector technology and relates to a combined dust collector. Background Technology

[0002] Each vehicle has a pipeline that runs through it, supplying compressed air; this is called the train pipe. The train pipes are connected in series, ensuring continuity from front to back. Each vehicle's train pipe delivers compressed air to the braking system via a brake branch pipe. A combined dust collector is installed on the brake branch pipe connecting the train pipe and the braking system to filter impurities from the air, thereby extending the service life of the braking system. Therefore, the combined dust collector is an indispensable and crucial component in the train braking process.

[0003] A combined dust collector disclosed in Chinese patent CN210258426U includes a dust collector housing, a dust collection section, and a cut-off gate. The dust collector housing has an air inlet and an air outlet. The dust collection section includes a dust collection box and a dust-stopping umbrella. The dust-stopping umbrella has an umbrella surface and an umbrella cap. The outer surface of the umbrella surface has longitudinal dust-guiding grooves. The dust collection box is fixedly connected to the dust collector housing. The umbrella surface is located at the connection between the dust collection box and the dust collector housing. The cut-off gate is disposed inside the dust collector housing. This existing dust collector, in use, only utilizes the cyclone principle to filter dust and impurities in the gas, resulting in insufficient filtration of impurities and affecting the service life of the braking device.

[0004] A combined dust collector for trains, disclosed in Chinese patent CN209438298U, includes a first housing, a dust collection box, a second housing, and a handle. A first slot is formed on one surface of the first housing, and a second slot is formed on its peripheral side. A first tube is fixed to the inner wall of the first slot, and a first filter screen is fixed to the inner wall of the first tube. A first support rod is rotatably connected to one surface of the first filter screen via a bearing. A turbine fan is fixed to the first support rod, and a second fixing plate is fixed to the other end of the first support rod. This existing combined dust collector uses a motor to drive an exhaust fan, which draws air from the dust collection box through the second filter screen and into the first tube via a fourth tube. This creates suction for dust and impurities falling onto the dust collection plate, resulting in cleaner exhaust air. However, after a period of use, dust and impurities accumulate on the upper surface of the second filter screen, clogging it and reducing its filtration efficiency, thus affecting its adsorption efficiency for dust and impurities on the dust collection plate.

[0005] To address the aforementioned problems, this utility model proposes a combined dust collector. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: A combined dust collector includes a dust collection box 1 and a shell 2. The shell 2 is fixedly installed on the top of the dust collection box 1. A first pipe 3 is fixedly connected to the top of the shell 2. A second pipe 4 is fixedly connected to the side wall of the shell 2. A valve 5 is provided on the second pipe 4. An umbrella-shaped dust collection plate 6 is fixedly installed at the top of the interior of the dust collection box 1.

[0028] An exhaust fan 7 is installed at the bottom of the dust collection box 1.

[0029] Specifically, a drive motor 21 is fixedly installed at the bottom of the dust collection box 1, and an exhaust fan 7 is fixedly installed on the output shaft of the drive motor 21.

[0030] A third tube 22 is fixedly connected to the bottom of the side wall of the dust collection box 1, and the other end of the third tube 22 is fixedly connected to the first tube 3.

[0031] A first filter plate 8 is slidably installed on the dust collection box 1 between the umbrella-shaped dust collection plate 6 and the exhaust fan 7.

[0032] The output shaft of the drive motor 21 rotates, causing the exhaust fan 7 to rotate, so that the exhaust fan 7 draws the air in the dust collection box 1 into the first pipe 3 after it has been filtered by the first filter plate 8 and then enters the first pipe 3 along the third pipe 22.

[0033] Specifically, a chute 9 is provided on one side of the dust collection box 1. The first filter plate 8 is slidably installed inside the chute 9. A pull plate 10 is fixedly connected to the side wall of the first filter plate 8 at the opening of the chute 9. The pull plate 10 extends out of the interior of the chute 9 and has a pull groove 11.

[0034] Furthermore, a fixing plate 12 is fixedly installed on the side wall of the dust collection box 1, and a limit rod 13 is slidably installed on the fixing plate 12. A limit hole is opened on the pull plate 10 at the position corresponding to the limit rod 13. The bottom end of the limit rod 13 is inserted into the limit hole. A spring 14 is fixedly connected to the top end of the limit rod 13. The spring 14 is sleeved on the outside of the limit rod 13, and the bottom end of the spring 14 is fixedly connected to the upper end face of the fixing plate 12.

[0035] The dust collection box 1 is equipped with a dust collection component for cleaning the first filter plate 8.

[0036] The dust collection assembly includes a scraper 15 and a collection trough 16. The scraper 15 and the collection trough 16 are fixedly installed on one side of the inner wall of the dust collection box 1, corresponding to the opening of the slide groove 9. Both the scraper 15 and the collection trough 16 are semi-circular. The lower end face of the scraper 15 is in contact with the upper end face of the first filter plate 8. The top of the collection trough 16 is close to the bottom surface of the first filter plate 8.

[0037] The second filter plate 17 is fixedly installed inside the first tube body 3. A rotating shaft 18 is rotatably installed at the center of the lower end face of the second filter plate 17. A turbine fan 19 is fixedly installed at the bottom end of the rotating shaft 18. Brushes 20 are fixedly installed on both sides of the outer surface of the rotating shaft 18, and the brushes 20 are in contact with the lower end face of the second filter plate 17.

[0038] Working principle:

[0039] In use, valve 5 is opened, allowing air from the second tube 4 to enter the housing 2. The air is filtered within the housing 2 using a swirling flow principle, causing dust and impurities to fall onto the umbrella-shaped dust collection plate 6. The drive motor 21 is then started, and its output shaft rotates, driving the exhaust fan 7. The exhaust fan 7 draws air from the dust collection box 1 through the first filter plate 8 and into the first tube 3 via the third tube 22. This creates suction on the dust and impurities on the umbrella-shaped dust collection plate 6, ensuring they fall into the dust collection box 1 as much as possible. The air processed by the swirling flow principle then enters the first tube 3 and is further filtered by the second filter plate 17 fixed to the first tube 3. This results in higher cleanliness of the air discharged along the first tube 3, thus protecting the normal operation of the train's braking system.

[0040] The airflow entering the first tube 3 will drive the turbine fan 19 to rotate, causing the brush 20 fixed on the rotating shaft 18 to rotate as well. This allows the brush 20 to clean the lower end surface of the second filter plate 17, so that the cleaned dust and impurities are re-sedied.

[0041] When there is a lot of dust and impurities on the upper surface of the first filter plate 8, the limiting rod 13 is pulled upwards, causing the spring 14 to be stretched and disengaging the limiting rod 13 from the limiting hole on the pull plate 10, thereby releasing the limitation on the pull plate 10. Then, the pull plate 10 is pulled through the pull groove 11, causing the pull plate 10 to move the first filter plate 8 to the outside of the dust collection box 1. During the movement of the first filter plate 8 inside the slide groove 9, the scraper 15 blocks the dust and impurities on the upper surface of the first filter plate 8 inside the scraper 15. When the side of the first filter plate 8 away from the scraper 15 moves to below the scraper 15, the dust and impurities are pushed down by the scraper 15 into the collection groove 16, where they are collected. Then, the first filter plate 8 is reset, thereby ensuring the filtration efficiency of the first filter plate 8.

[0042] Example 2: Figures 7-8 As shown, the difference between this embodiment and Embodiment 1 is that the dust collection assembly further includes a vacuum cleaner 23, a suction pipe 24, and a collection box 25. The vacuum cleaner 23 is fixedly installed on the side wall of the dust collection box 1, and the suction end of the vacuum cleaner 23 is fixedly connected to the suction pipe 24, which communicates with the interior of the collection trough 16. The collection box 25 is fixedly installed on the side wall of the dust collection box 1, and the collection box 25 communicates with the discharge end of the vacuum cleaner 23.

[0043] Working principle:

[0044] The difference between this embodiment and embodiment 1 is that it is easier to remove dust and impurities from inside the collection tank 16 during operation; the rest of the operation is the same as in embodiment 1.

[0045] The specific working principle is as follows: when there is too much dust and impurities collected inside the collection tank 16, the vacuum cleaner 23 is started, and the vacuum cleaner 23 discharges the dust and impurities inside the collection tank 16 into the collection box 25 through the suction pipe 24.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
