Description

Technical Field

[0001] The utility model relates to the technical field of flue carbon removal, in particular to a flue carbon removal device for a natural gas boiler. Background Art

[0002] At present, during the operation of existing natural gas boilers, carbon deposits are easily deposited on the inner wall of the internal flue due to the need to exhaust smoke, which is difficult to clean and reduces the working efficiency of the machine to a certain extent.

[0003] In the solutions in the prior art, a motor is generally used to drive the shaft to rotate, and then the shaft drives the scraper to rotate for scraping. However, the dust inside the flue will be scattered during rotation, resulting in incomplete cleaning. At the same time, if the internal dust is cleaned immediately after cleaning, fine dust will fly out directly. If cleaning is done after a while, the cleaning efficiency will be reduced. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a natural gas boiler flue carbon removal device, which aims to improve the problem that rotary cleaning causes dust inside the flue to fly, resulting in poor cleaning effect and low efficiency.

A plurality of plug blocks are fixedly installed on the inner wall of the skateboard. A slot matching the plug block is arranged at the top of the support ring. The support ring and the skateboard are connected through the cooperation of the plug block and the slot. The plug block is arranged in a T shape.

[0010] In the preferred technical solution of the present utility model, the positioning assembly includes a circular ring, a side plate and a positioning rod. The support ring is hollow, and the circular ring is rotatably installed on the bottom end of the inner wall of the support ring. A plurality of side plates are fixedly installed on the top of the circular ring, and the positioning rod is fixedly installed on one side of the side plate. Each positioning rod slides through one side of the support ring and extends into the slot. A positioning hole matching the positioning rod is provided on the insert block, and an adjustment assembly is provided at the bottom end of the circular ring. The positioning rod is arc-shaped, and the circle of the positioning rod is the same as the center of the support ring.

[0011] In the preferred technical solution of the present utility model, the adjustment component includes a telescopic rod and a round box, a slider is fixedly installed at the bottom end of the round ring, and an annular sliding hole matching the slider is provided at the bottom end of the support ring. The round box is rotatably installed on one side of the bottom end of the support ring, a torsion spring is fixedly installed between the inner wall of the round box and the support ring, and the telescopic rod is fixedly installed between the outer side of the round box and the slider. The telescopic rod consists of a first pull rod and a second pull rod, and the second pull rod is slidably sleeved on the first pull rod.

[0012] The beneficial effects of the utility model are as follows: the utility model obtains a natural gas boiler flue carbon removal device through the above design. During cleaning, the starting motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the support plate to move downward. The support plate moves downward and drives the scraper to move downward through the support ring and the slide plate to scrape and clean the dust on the inner wall of the shell to the bottom of the shell, and then the sliding door is opened for cleaning. When the scraper needs to be disassembled for cleaning, the slider is pushed to drive the circular ring to rotate, and at the same time, the telescopic rod drives the round box to rotate to squeeze the torsion spring. The rotation of the circular ring drives the positioning rod to move and retract into the support ring through the side plate. At this time, the slide plate can be removed. This device is convenient for cleaning the flue and can prevent dust from flying during cleaning, thereby improving the cleaning efficiency. At the same time, the scraper is easy to disassemble, and is convenient for replacement and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
