Description

Technical Field

[0001] The invention belongs to the technical field of boiler carbon residue measurement, and in particular relates to an automatic trace carbon residue measuring instrument for boilers. Background Art

[0002] The boiler carbon residue measuring instrument is a device specially used to measure the residue content of coal or other fuels after combustion in the boiler. The working principle of the boiler carbon residue measuring instrument is usually based on the combustion method. The two most common methods are aerobic combustion method and oxygen flow combustion method. The carbon residue content can be determined by controlling the combustion conditions and collecting residual substances, or by measuring the carbon dioxide content in the gas after combustion, the carbon residue content can be indirectly determined. By accurately measuring the carbon residue content of coal or other fuels, it can provide important basis for boiler combustion efficiency, fuel quality and environmental protection.

[0003] Common boiler carbon residue measuring instruments collect the residue on the inner wall of the boiler, burn the collected residue, and determine the boiler carbon residue content based on the combustion products.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] For specific embodiment 1, please refer to Figure 1-7 The present invention discloses an automatic trace carbon residue measuring instrument for boilers, comprising a carbon residue measuring instrument body 1. Specifically, a feed hopper 101 connected to the interior of the carbon residue measuring instrument body 1 is fixedly connected to the upper surface of the carbon residue measuring instrument body 1, and the feed hopper 101 is composed of a hollow column and a conical hopper connected to each other; a feed assembly 2 is fixedly connected to the upper surface of the carbon residue measuring instrument body 1, and the feed assembly 2 comprises a feed control column 201 and a cleaning scraper 202 which can move up and down, the feed control column 201 is in contact with the inner wall of the hollow column of the feed hopper 101, the cleaning scraper 202 is in contact with the inner wall of the conical hopper of the feed hopper 101, and the cleaning scraper 202 rotates to scrape and clean the inner wall of the conical hopper of the feed hopper 101 to prevent raw materials from adhering to the inner wall and affecting the measurement accuracy.

[0027] Furthermore, an adjustment component 3 is fixedly connected to the upper surface of the carbon residue measuring instrument body 1, and the adjustment component 3 includes an adjustment connecting rod 301 that is symmetrically arranged for rotation. As the feed control column 201 rotates, the adjustment connecting rod 301 swings back and forth. An adjustment slider 302 is provided at one end of the adjustment connecting rod 301. The adjustment slider 302 slides with the feed component 2. The adjustment connecting rod 301 rotates back and forth, and the feed control column 201 and the cleaning scraper 202 are driven to move up and down synchronously through the adjustment slider 302. When the feed control column 201 leaves the hollow column of the feed hopper 101, the feed hopper 101 opens and the carbon residue raw material to be measured falls into the interior of the carbon residue measuring instrument body 1 for measurement.

[0028] The operation process of this embodiment is: put the raw material to be tested in the boiler into the feed hopper 101, and drive the feed control column 201 to rotate. During this process, the cleaning scraper 202 rotates along the inner wall of the conical bucket of the feed hopper 101, and at the same time, the adjusting connecting rod 301 rotates back and forth, driving the feed control column 201 to move up and down. During the upward movement of the feed control column 201, when the feed control column 201 is away from the hollow column part of the feed hopper 101, the feed hopper 101 is opened, and the raw material to be tested falls into the interior of the residual carbon measuring instrument body 1, and is tested to measure the residual carbon in the boiler; during the downward movement of the feed control column 201, when the feed control column 201 is located inside the hollow column of the feed hopper 101, the feed hopper 101 is closed, and the raw material to be tested stops falling. By controlling the intermittent entry of the raw material to be tested, the accuracy of the residual carbon measurement is guaranteed.

[0029] For specific embodiment 2, please refer to Figure 1-7 On the basis of the specific embodiment 1, specifically, the feed assembly 2 also includes a feed support frame 203 fixedly connected to the upper surface of the carbon residue measuring instrument body 1, a drive shaft 204 is rotatably arranged on the lower surface of the feed support frame 203, a drive motor 205 is fixedly installed on the upper surface of the feed support frame 203, and the output shaft of the drive motor 205 is fixedly connected to the drive shaft 204; a drive worm 206 is fixedly connected to the side surface of the drive shaft 204, and a limiting convex strip 207 is symmetrically fixedly connected to the side surface of the drive shaft 204.

[0030] Furthermore, a hollow support column 208 is fixedly connected to the upper surface of the feed control column 201, a transmission wheel 209 is fixedly connected to the upper surface of the hollow support column 208, the hollow support column 208 is slidingly matched with the limiting protrusion 207 and the drive shaft 204, and the transmission wheel 209 is slidingly matched with the limiting protrusion 207 and the drive shaft 204; two first ear plates are symmetrically fixedly connected to the side of the hollow support column 208, a transmission connecting rod 210 is rotatably connected to the side of the first ear plate, one end of the transmission connecting rod 210 is rotatably connected to the corresponding cleaning scraper 202 through the second ear plate, and an arc spring 211 is fixedly connected between two adjacent transmission connecting rods 210, and the arc spring 211 is in a compressed state, so that the cleaning scraper 202 fits against the inner wall of the conical bucket of the feed hopper 101.

[0031] Furthermore, the adjustment component 3 also includes a support plate 303 fixedly connected to the upper surface of the carbon residue measuring instrument body 1, two second ear plates are symmetrically fixedly connected to one side of the support plate 303, and transmission grooves are opened on the surfaces of the two adjustment connecting rods 301, the adjustment slider 302 is slidably set inside the transmission wheel 209, and the outer wall of the adjustment slider 302 is fixedly connected to a transmission pillar that slides with the transmission groove; an extension support plate 304 is fixedly connected to one side of the support plate 303 close to the adjustment connecting rod 301, and a transmission turbine 305 is rotatably connected to one side of the extension support plate 304, and the transmission turbine 305 is adapted to the driving worm 206; a transmission disc 306 is fixedly connected to one side of the transmission turbine 305, and a lifting link 307 is rotatably connected at an eccentric position of the transmission disc 306, and one end of the lifting link 307 is rotatably connected to the side surface of the transmission pillar.

Under the cooperation of the driving worm 206 and the transmission turbine 305, the transmission turbine 305 rotates and drives the transmission disc 306 to rotate synchronously. Since one end of the lifting link 307 is rotatably connected to the eccentric position of the transmission disc 306, the lifting link 307 moves up and down with the rotation of the transmission disc 306. Under the connection action of the transmission support, the movement of the lifting link 307 drives the two adjusting links 301 to rotate reciprocatingly.

When the feed control column 201 is away from the hollow column part of the feed hopper 101, the feed hopper 101 is opened, and the raw material to be tested falls into the interior of the residual carbon measuring instrument body 1 through the feed hopper 101 for testing so as to measure the residual carbon in the boiler; when the adjusting link 301 rotates downward, it drives the feed control column 201 to move toward the hollow column part close to the feed hopper 101. When the feed control column 201 is located inside the hollow column part of the feed hopper 101, the feed hopper 101 is closed, and the raw material to be tested stops falling.

[0034] During the rotation of the driving shaft 204, under the cooperation of the limiting convex strip 207 and the hollow support column 208, the hollow support column 208 rotates synchronously, and the cleaning scraper 202 is driven to rotate synchronously through the transmission connecting rod 210. The cleaning scraper 202 is moved to scrape the inner wall of the conical bucket of the feed hopper 101 to prevent raw materials from adhering.
