Description

Technical Field

[0001] This utility model relates to the field of dust collector hopper technology, and more specifically, to a dust collector hopper for explosion-proof dust collectors. Background Technology

[0002] Explosion-proof dust collectors are core equipment for industrial dust control and safety protection. As a key component for dust collection and emission, the smoothness of dust discharge and the reliability of sealing of the ash hopper directly affect the operating efficiency and explosion-proof safety of the dust collector.

[0003] In existing technologies, such as Chinese patent document CN222240750U, a dust collector hopper anti-clogging device is disclosed. This device is driven by a motor, with a rotating shaft extending into the dust hopper driving a gear that meshes with a toothed ring mounted on the top of the inner wall of the dust hopper, thereby driving a scraper to rotate and clean the inner wall. However, the gear and toothed ring are directly arranged inside the dust hopper, which is constantly filled with a large amount of dust. Dust can easily enter the meshing gap between the gear and the toothed ring, causing abrasive wear, accelerating tooth surface damage, and in severe cases, causing jamming. Utility Model Content

[0010] Through the above technical solution, the vibrating motor can drive the ash hopper to vibrate, shaking off the stubborn dust adhering to the inner wall of the ash hopper.

[0011] Preferably, a connecting ring is fixedly connected to the top of the first corrugated expansion tube, and a fixing ring is fixedly connected to the bottom of the second corrugated expansion tube, with a connecting flange fixedly connected to the bottom of the fixing ring.

[0028] 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.

[0029] like Figure 1 and Figure 2As shown, a dust hopper for an explosion-proof dust collector includes a dust hopper 7 and a driving component. A first corrugated telescopic pipe 6 is fixedly connected to the top of the dust hopper 7, and a second corrugated telescopic pipe 8 is fixedly connected to its bottom. The dust hopper 7 is connected to the equipment via the first corrugated telescopic pipe 6 and the second corrugated telescopic pipe 8. Multiple vibrating plates 11 are arranged on the inner wall of the dust hopper 7, with a uniform gap between each vibrating plate 11 and the inner wall. Compression springs 13 are fixedly connected to both ends of each vibrating plate 11, with the ends of the springs 13 fixedly connected to the inner wall of the dust hopper 7. Multiple vibrating discs 12 are fixedly connected to the outer wall of the vibrating plates 11. The driving component drives the dust hopper 7 to vibrate. The vibrating plates 11 and vibrating discs 12 cooperate to clean dust through vibration, preventing dust from entering the transmission gap and causing wear or jamming. The corrugated telescopic pipes adapt to vibration displacement, ensuring the sealing and stability of the connection between the dust hopper 7 and the equipment.

[0030] The ash hopper 7, vibrating plate 11, and vibrating disc 12 are all made of metal materials with good conductivity, such as stainless steel. A dedicated grounding terminal is provided on the mounting ring 19 or the outer wall of the ash hopper 7. It is reliably connected to the grounding system of the dust collector body through a wire to promptly dissipate static electricity that may be generated by dust friction and meet the explosion-proof requirements.

[0031] like Figure 2 As shown, the upper section of the ash hopper 7 is conical, and the lower section is cylindrical. The lower end of the vibrating plate 11 extends vertically downward into the cylinder of the lower section of the ash hopper 7. The conical structure of the upper section of the ash hopper 7 facilitates the falling of dust, while the cylindrical structure of the lower section facilitates the concentrated discharge of dust. The extension of the vibrating plate 11 into the lower cylinder expands the coverage area of ​​the vibration cleaning, prevents dust accumulation on the inner wall of the lower cylinder, and improves the anti-clogging effect.

[0032] like Figure 2 As shown, the driving component is a vibration motor 14, and the output end of the vibration motor 14 is fixedly connected to the ash hopper 7. The vibration motor 14 can drive the ash hopper 7 to vibrate, shaking off the stubborn dust adhering to the inner wall of the ash hopper 7.

[0033] In some embodiments, the vibratory motor 14 can be an explosion-proof vibratory motor. Explosion-proof vibratory motors are common equipment in the prior art, and the principle of generating excitation force by the rotation of its internal eccentric block is common knowledge in the art and will not be elaborated here. The vibratory motor 14 is fixedly connected to the lower outer wall of the ash hopper 7 through a vibration damping connection assembly. Specifically, the output shaft of the vibratory motor 14 is connected to a force transmission plate, which is connected to the outer wall of the ash hopper 7 by bolts. At least two layers of high-strength rubber vibration damping pads are sandwiched between the force transmission plate and the outer wall of the ash hopper 7. The fixed frame 2 is mainly used to accommodate and protect the vibratory motor 14 and its wiring, and does not directly bear the main vibration load. The vibration force generated by the vibratory motor 14 is buffered and adjusted by the vibration damping pads before being transmitted to the ash hopper 7, thereby reducing the vibration impact on the fixed frame 2 and the mounting frame 1. By setting a vibration damping connection assembly containing rubber vibration damping pads to install the vibratory motor, the direct impact and transmission of the vibratory motor to the fixed frame 2 and the mounting foundation during operation are effectively buffered and isolated, improving the stability and service life of the overall structure and reducing noise.

[0034] like Figure 2 As shown, a connecting ring 5 is fixedly connected to the top of the first corrugated expansion pipe 6, and a fixing ring 9 is fixedly connected to the bottom of the second corrugated expansion pipe 8. A connecting flange 10 is fixedly connected to the bottom of the fixing ring 9. The connecting ring 5, the fixing ring 9, and the connecting flange 10 facilitate the connection between the ash hopper 7 and the equipment.

[0035] like Figure 1 and Figure 2 As shown, an installation frame 1 is fitted onto the outer wall of the ash hopper 7. A mating ring 3 is fixedly connected to both the installation frame 1 and the outer circumference of the connecting ring 5. Each mating ring 3 has an installation hole 4 at its top. The design of the mating ring 3 facilitates the installation of the ash hopper 7.

[0036] like Figure 4 As shown, multiple sliding holes 15 are formed at the bottom of the inner wall of the mounting frame 1 along the vibration direction. A sliding rod 16 is fixedly connected to the inner wall of each sliding hole 15. A return spring 17 is fitted at both ends of each sliding rod 16. A slider 18 is slidably connected to the outer wall of each sliding rod 16. An mounting ring 19 is fixedly connected to the outer wall of the ash hopper 7. The bottom of each mounting ring 19 is fixedly connected to the slider 18. One end of each return spring 17 is fixedly connected to the slider 18, and the other end is fixedly connected to the inner wall of the mounting frame 1. The sliding cooperation between the sliding rod 16 and the slider 18 provides guidance for the vibration of the ash hopper 7, ensuring stable vibration direction and preventing deviation. The return spring 17 assists in the vibration reset of the ash hopper 7 and buffers vibration impact. Simultaneously, the connection between the slider 18 and the mounting ring 19 can lift the ash hopper 7, preventing excessive pulling on the first corrugated telescopic tube 6.

[0037] like Figure 2 As shown, a fixed frame 2 is fixedly connected to the bottom of the mounting frame 1, and the vibration motor 14 is fixedly connected to the inner wall of the fixed frame 2. The design of the fixed frame 2 facilitates the installation of the vibration motor 14.

[0038] In use, firstly, the ash hopper 7 is connected to the relevant components of the explosion-proof dust collector via the connecting ring 5, the fixing ring 9, the connecting flange 10, and the mounting hole 4 on the mating ring 3, through the first corrugated telescopic tube 6 and the second corrugated telescopic tube 8. Then, the vibration motor 14 is turned on, and the output end of the vibration motor 14 drives the ash hopper 7 to vibrate. When the ash hopper 7 vibrates, the mounting ring 19 drives the slider 18 to slide along the slide rod 16, and the return spring 17 is repeatedly compressed and extended to assist the vibration of the ash hopper 7. At the same time, the vibration plate 11 on the inner wall of the ash hopper 7 vibrates synchronously under the action of vibration. Under the action of the compression spring 13, the vibration plate 12 on the vibration plate 11 can enhance the vibration effect and shake off the dust attached to the inner wall of the ash hopper 7. The uniform gap between the vibration plate 11 and the inner wall of the ash hopper 7 ensures that the vibration plate 11 does not collide with the inner wall of the ash hopper 7 when it shakes.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
