Description

Technical Field

[0001] The utility model belongs to the technical field related to dust discharge of dust collectors, and particularly relates to an ash discharge hopper for a bag dust collector. Background Technique

[0002] A bag dust collector is a dry dust filtering device. It is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper.

[0003] After retrieval, the publication number: CN220779483U discloses an ash discharge hopper for a bag dust collector. In the utility model, when it is necessary to clean the ash discharge hopper at the bottom of the dust collector, first, the position of the scraper is adjusted through the telescopic rod so as to clean more completely. By starting the motor, the motor drives the transmission rod to rotate, and then the transmission rod drives the telescopic rods on both sides to rotate, thereby driving the scraper to clean the ash discharge hopper at the bottom of the dust collector, avoiding excessive dust accumulation inside it and affecting the dust removal effect. Since the bag dust is relatively fine and the ash receiving surface of the traditional ash discharge hopper is a smooth flow channel, the effect of frequent cleaning is not significant, and there is a gap at the interface between the dust discharge port of the dust collector and the ash hopper, and fine dust will fill outside the ash discharge hopper under the action of inertia, thereby affecting the surrounding environment.

[0004] Therefore, an ash discharge hopper for a bag dust collector is designed to solve the above problems. Content of the Utility Model

[0005] To solve the problems raised in the above background technique. The utility model provides an ash discharge hopper for a bag dust collector. Multiple groups of converging type blanking plates are combined into a converging ash hopper-shaped structure, and the assembled converging type blanking plates are placed at the lower end of the dust discharge port of the dust collector. During ash discharge, the suction ash slides down along the slope of the converging type blanking plate. During this process, in order to avoid fine ash diffusing at the upper end of the converging type blanking plate under the action of inertia, the blower outside the connecting frame of the device can be started synchronously. Under negative pressure conditions, the fine ash is sucked into the square ash suction pipe from the inclined converging suction head. The suction nozzles of the converging suction head are distributed obliquely upward at 30° at the upper end of the converging type blanking plate, so that the converging suction head can only suck the floating ash above, thereby ensuring the cleanliness of the surrounding environment.

[0006] When sucking dust, to avoid dust retention, the vibration motor outside the threaded steel plate can be started through the control end. The vibration motor drives the conical feeding plate and the longitudinally convex plates welded on the surface to vibrate at high frequency, thereby accelerating the ash discharging rate. On the other hand, the stepping motor inside the dust-proof cover is electrically started, and its motor shaft drives the brush roller to rotate. The brush roller repeatedly sweeps along the inner wall of the feeding port of the fixed frame to ensure the normal progress of ash discharging, prevent blockage, and the fine ash finally falls into the collection box together, which is convenient for collection.

[0007] To achieve the above object, the present utility model provides the following technical solutions: An ash discharge hopper for a bag filter, including a shaking type ash discharge structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1 shown:

[0025] A dust discharge hopper for a bag filter. As known from CN220779483U, by starting the motor, the motor drives the transmission rod to rotate, and then the transmission rod drives the telescopic rods on both sides to rotate, thereby driving the scraper to clean the dust discharge hopper at the bottom of the dust collector, avoiding excessive dust accumulation inside and affecting the dust removal effect. Since the dust in the bag is relatively fine and the ash receiving surface of the traditional dust discharge hopper is a smooth flow channel, the effect of frequent cleaning is not significant. Moreover, there is a gap between the dust discharge port of the dust collector and the interface of the hopper, and fine dust will fill outside the dust discharge hopper under the action of inertia, thereby affecting the surrounding environment. On this basis, a jitter-type dust discharge structure 1 is added.

[0026] As Figure 1 、 Figure 2 and Figure 3 shown:

[0027] In an alternative embodiment: The jitter-type dust discharge structure 1 includes support legs 11, a converging type blanking plate 12, a square dust suction pipe 13, converging suction heads 14, a blower 15, and a dust discharge pipe 16. The converging type blanking plate 12 is fixedly connected to the top of the support legs 11. The square dust suction pipe 13 is arranged at the upper end of the converging type blanking plate 12. The converging suction heads 14 are arranged at equal intervals on the top of the square dust suction pipe 13. The input end of the blower 15 is fixedly connected to the bottom of the square dust suction pipe 13. The dust discharge pipe 16 is clamped outside the output end of the blower 15. There are several groups of converging suction heads 14, and several groups of converging suction heads 14 are inclined at 30° in the vertical direction and distributed on the top of the square dust suction pipe 13. There are also several groups of longitudinal convex plates 2 arranged inside the converging type blanking plate 12. The protruding surface of the protruding end of the longitudinal convex plate 2 is a precision grinding structure, and several groups of longitudinal convex plates 2 are arranged at equal intervals on the inner wall of the converging type blanking plate 12.

[0028] In this embodiment: Multiple groups of funnel-shaped discharging plates 12 are combined to form a funnel-shaped ash hopper structure, and the assembled funnel-shaped discharging plates 12 are placed at the lower end of the ash discharge port of the dust collector. During ash discharge, the sucked ash slides down along the slope of the funnel-shaped discharging plate 12. During this process, to prevent fine ash from spreading at the upper end of the funnel-shaped discharging plate 12 under the action of inertia, the blower 15 outside the connecting frame 9 can be started synchronously in this device. Under negative pressure conditions, the fine ash is sucked into the square ash suction pipe 13 from the inclined funnel-shaped suction head 14. The suction nozzles of the funnel-shaped suction head 14 are distributed obliquely upward at 30° at the upper end of the funnel-shaped discharging plate 12, so that the funnel-shaped suction head 14 can only suck the floating ash above, thereby ensuring the cleanliness of the surrounding environment.

[0029] Furthermore:

[0030] As Figure 1 、 Figure 3 and Figure 4 shown:

[0031] In an alternative embodiment: A threaded steel plate 3 and a vibration motor 4 are further provided outside the funnel-shaped discharging plate 12. The threaded steel plate 3 is fixedly connected to the outer wall surface of the funnel-shaped discharging plate 12, and the vibration motor 4 is threadedly connected to one side of the threaded steel plate 3. A fixed frame 5, a dust cover 6, a stepping motor 7 and a brush roller 8 are also provided at the bottom of the funnel-shaped discharging plate 12. The fixed frame 5 is fixedly connected to the bottom of the funnel-shaped discharging plate 12, the dust cover 6 is threadedly connected to one side of the fixed frame 5, the motor shaft of the stepping motor 7 is fixedly connected to one end of the brush roller 8 through a coupling, and the brush roller 8 is rotatably connected inside the fixed frame 5. A connecting frame 9 is also provided outside the blower 15, and one side of the connecting frame 9 is welded and fixed to the outer surface of the support leg 11.

[0032] In this embodiment: During ash suction, to prevent dust from staying, the vibration motor 4 outside the threaded steel plate 3 can be started through the control end. The vibration motor 4 drives the funnel-shaped discharging plate 12 and the longitudinally convex plate 2 welded on the surface to vibrate at a high frequency, thereby accelerating the ash discharging rate; on the other hand, the stepping motor 7 inside the dust cover 6 is electrically started, and its motor shaft drives the brush roller 8 to rotate. The brush roller 8 repeatedly sweeps along the inner wall of the discharge port of the fixed frame 5 to ensure the normal progress of ash discharging, prevent blockage, and finally the fine ash falls into the collection box 10 together, which is convenient for collection.
