The dust removing device is compact in structure, good in dust removing effect and convenient to use, and the roller cage and the spiral hanging plate are combined to remove dust.

Description

Spiral ash removal device driven by centering slider crank mechanism and application method thereof

Technical Field

The invention relates to a spiral ash removal device driven by a centering slider crank mechanism and a use method thereof.

Background

In the equipment with the smoke exhaust channel, because dust accumulation often exists in the flue, the normal use of the flue is affected, and the service life of the flue is easily reduced. Because the driving mechanism of the existing flue ash removal device is always arranged in the flue, the device is not only not applicable to the working environment of high temperature and high smoke and is easy to damage, but also difficult to repair and high in cost.

Disclosure of Invention

The invention aims to provide a spiral ash removal device driven by a centering sliding block crank mechanism and a use method thereof, which are compact in structure, good in ash removal effect and simple and convenient to use, and the rolling cage and the spiral hanging plate are combined for ash removal.

The technical scheme of the invention is as follows: the utility model provides a centering slider crank mechanism driven spiral ash removal device, includes the flue pipe, be provided with the rolling cage in the flue pipe, be provided with the spiral scraper blade that laminates mutually with the inside wall of flue pipe along the axial on the periphery of rolling cage, the one end of rolling cage stretches out the flue pipe and is connected with the centering slider crank mechanism that the drive rolling cage revolved.

Further, the rolling cage comprises two circular rings, fixing rods are arranged between the circular rings at intervals along the circumferential direction, and two ends of the spiral scraping plate are fixedly connected with the two circular rings respectively and spirally encircle the circumferential surface of the rolling cage formed by the fixing rods.

Further, the centering slider crank mechanism comprises a support arranged beside the flue pipe, a slider with the center at the same horizontal height as the center of the rolling cage is arranged on the support, the slider is driven by an electric push rod to realize reciprocating transverse sliding, a connecting rod is hinged to the slider, and the other end of the connecting rod is hinged to the end part of the rolling cage penetrating out of the flue pipe so as to drive the rolling cage to rotate.

Further, a transverse guide rail matched with the sliding block is arranged on the support, an annular end plate is fixed on the end part of the rolling cage penetrating out of the flue pipe, and the other end of the connecting rod is hinged with the annular end plate.

The application method of the spiral ash removal device driven by the centering slider crank mechanism comprises the following steps:

1) Starting the electric push rod to drive the sliding block to reciprocate and transversely slide and drive the roller to rotate, and discharging dust in the flue out of the flue pipe along the spiral line direction through the rotation of the rolling cage and the guiding action of the spiral scraping plate;

2) A receiving device is mounted at the other end of the flue pipe to receive the discharged dust.

Compared with the prior art, the invention has the following advantages:

1. the device adopts a spiral scraper to discharge the scraped dust out of the flue along a spiral line by the spiral scraper;

2. the centering slide block crank mechanism is used for driving to realize the circular motion of the rolling cage.

3. The transmission equipment is arranged outside the flue pipe, so that the operation under the condition of high temperature and high ash can be realized, the loss under severe conditions is prevented, and the cost is greatly reduced.

Detailed Description

In order to make the above features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.

Referring to FIG. 1

The utility model provides a centering slider crank mechanism driven spiral ash removal device, includes flue pipe 10, be provided with in the flue pipe and roll cage 20, be provided with on the periphery of rolling the cage along the axial and laminate spiral scraper blade 21 mutually with the inside wall of flue pipe, the one end of rolling the cage stretches out the flue pipe and is connected with centering slider crank mechanism to the drive is rolled the cage and is revolved and make spiral scraper blade accomplish the ash scraping process.

In this embodiment, the rolling cage includes two circular rings, fixing rods 22 are disposed between the circular rings along the circumferential direction at intervals, and two ends of the spiral scraping plate are fixedly connected with the two circular rings respectively and spirally encircle the circumferential surface of the rolling cage formed by the fixing rods.

In this embodiment, the centering slider crank mechanism includes a bracket 31 disposed beside the flue pipe, a slider 32 having a center at the same level as the center of the rolling cage is disposed on the bracket, the slider is driven by an electric push rod 35 to realize reciprocating transverse sliding, a connecting rod 33 is hinged on the slider, and the other end of the connecting rod is hinged with the end portion of the rolling cage penetrating out of the flue pipe to drive the rolling cage to rotate.

In this embodiment, the bracket is provided with a transverse guide rail 34 which is matched with the sliding block so as to guide the sliding block. The end part of the rolling cage penetrating out of the flue pipe is fixedly provided with an annular end plate 23, and the other end of the connecting rod is hinged with the annular end plate, so that the rolling cage is rotated through the annular end plate.

The working principle of the device is as follows: firstly, the sliding block is driven to move back and forth in the transverse guide rail by controlling the expansion and contraction of the electric push rod, the center of the sliding block and the center of the rolling cage are at uniform horizontal height, and the left and right movement of the sliding block in the guide rail is converted into circular movement of the rolling cage through the action of the connecting rod. Meanwhile, the spiral scraping plate is further arranged on the rolling cage, and dust in the flue is discharged out of the flue along the spiral line direction through the rotation of the rolling cage and the guiding function of the spiral scraping plate, so that the dust removing function of the flue is realized.

The above description is only of the preferred embodiments of the present invention, and it will be apparent to those skilled in the art from this disclosure that it is not necessary to devise a kind of spiral soot cleaning device driven by a centering slider crank mechanism in various forms according to the teachings of the present invention, and it is intended to cover all equivalent changes, modifications, substitutions and alterations herein without departing from the spirit and scope of the present invention.
