Description

Technical Field

[0001] The invention relates to the technical field of energy-saving coating feeding, in particular to an energy-saving coating calcining feeding device for an industrial kiln. Background Art

[0002] Energy-saving coating is a coating with high emissivity, high temperature resistance, corrosion resistance and high bonding strength with furnace substrate. Energy-saving coating can be applied to various kilns in the steel, ceramics, refractory and other industries, including the inner wall of various refractory substrates such as heating furnaces, hot air furnaces, tunnel kilns, etc. Energy-saving radiation treatment can not only save energy but also protect the furnace body and extend the life of the furnace body. Due to the increasing demand for energy-saving coatings in various industries, it is necessary to improve the production efficiency of energy-saving coatings.

[0003] In the actual production process of energy-saving coatings, it is necessary to calcine the raw materials of energy-saving coatings to produce crude energy-saving coatings, and further process the crude energy-saving coatings to obtain refined energy-saving coatings. The feeding part of the energy-saving coatings before calcination is realized by simple transmission, and the energy-saving coating calcination raw materials are evenly sprinkled inside the calcining furnace through a uniform sprinkling device.

[0004] This method of feeding the energy-saving coating calcined raw materials can increase the calcination effect and calcination efficiency of the energy-saving coating calcined raw materials by sprinkling the energy-saving coating calcined raw materials. However, since the calcination raw materials of the energy-saving coating are not crushed thoroughly during the processing of the raw materials, larger particles are mixed therein, which leads to insufficient contact between the calcination raw materials of the energy-saving coating, thereby affecting the calcination effect and calcination efficiency. In addition, since the powdered energy-saving coating calcined raw materials have strong adhesion, the calcination raw materials of the energy-saving coating will adhere to the feeding device and the wall of the calcination furnace, thereby affecting the utilization rate of the energy-saving coating calcination raw materials. In addition, since simple uniform sprinkling cannot make the internal mixing of the calcination raw materials of the energy-saving coating sufficient, the calcination raw materials of the energy-saving coating are not in sufficient contact, which affects its calcination effect and calcination efficiency.

A feeding trough is arranged in the middle of the closing plate 1. A rolling cylinder 2 is mounted on the side wall of the calcining furnace through a U-shaped fixing rod 11 symmetrically arranged on the left and right.

The feeding portion 4 passes through the feeding trough and extends to the inside of the calcining furnace. A cleaning portion 5 is arranged at the bottom of the feeding portion 4 and below the closing plate 1.

[0031] The present invention further crushes the energy-saving coating calcined raw materials through the rolling component 21, so that the energy-saving coating calcined raw materials react more fully during the calcination process, and scrapes and mixes the powdered energy-saving coating calcined raw materials adhered to the rolling cylinder 2 through the mobile scraping part 3 and the mixing component 22, thereby improving the utilization rate of the energy-saving coating calcined raw materials and fully mixing the energy-saving coating calcined raw materials, thereby increasing the contact and mixing degree of the energy-saving coating calcined raw materials during the calcination process to increase the calcination effect, and further scrapes the powdered energy-saving coating calcined raw materials adhered to the inner wall of the calcination furnace by the cleaning part 5, so that the energy-saving coating calcined raw materials adhered to the inner wall of the calcination furnace are fully cleaned, thereby further improving the utilization rate of the energy-saving coating calcined raw materials.

[0032] Specifically, the energy-saving coating calcined raw materials are first poured into the rolling drum 2 from the feed port, and then the rolling component 21 is controlled to further roll the poured energy-saving coating calcined raw materials to make them completely crushed into powder, and as the rolling component 21 rolls, the moving scraper part 3 and the mixing component 22 will scrape off the energy-saving coating calcined raw materials adhering to the side wall of the rolling drum 2 and mix them, and the mixed energy-saving coating calcined raw materials will be transferred from the discharge port 23 to the feeding part 4 position, and transported to the calcining furnace via the feeding part 4, and at the same time, the cleaning part 5 will fully scrape off the energy-saving coating calcined raw materials adhering to the side wall of the calcining furnace due to being transported to the calcining furnace, so that all the energy-saving coating calcined raw materials fall to the bottom of the calcining furnace.

[0033] It should be noted that the feeding section 4 and the cleaning section 5 are both located at the top of the calcining furnace and away from the calcining position of the calcining raw materials for the energy-saving coating, so as to prevent the high temperature environment formed when the calcining raw materials for the energy-saving coating from causing damage or affecting some parts of the feeding section 4 and the cleaning section 5, thereby ensuring that the feeding section 4 and the cleaning section 5 can operate normally and achieve the purpose of feeding and cleaning the inner wall of the calcining furnace.

The output sections of the two No. 1 motors 211 are fixed with a rotating shaft 212 that penetrates the rear wall of the rolling drum 2. The front end of the rotating shaft 212 is rotatably installed on the front wall of the rolling drum 2. A rolling roller 213 is fixed on each rotating shaft 212. The rolling assembly 21 is used to roll and completely crush the energy-saving paint calcined raw materials, which is mainly achieved by rotating the two rolling rollers 213 in opposite directions, so that the energy-saving paint calcined raw materials between the two rolling rollers 213 are rolled and crushed.

[0035] See also Figure 4-Figure 5 The movable scraping part 3 includes a rotating disk 31 arranged at the front end of each rotating shaft 212, and each rotating disk 31 is provided with a transmission structure, and the transmission structure includes a connecting rod 311 rotatably installed on the rotating disk 31, and the end of the connecting rod 311 away from the rotating disk 31 is hinged with a U-shaped synchronization rod 312, and the U-shaped synchronization rod 312 is located in the horizontal section of the rear side and the end close to the rolling cylinder 2 passes through the side wall of the rolling cylinder 2 and is slidably connected with it. The U-shaped synchronization rod 312 is located in the horizontal section of the rear side and the end located in the rolling cylinder 2 is hinged with a transmission rod 313, and the end of the transmission rod 313 away from the U-shaped synchronization rod 312 is installed with a roller wall scraping component 32, and the bottom of the roller wall scraping component 32 is respectively provided with a first oblique scraping component 33 and a second oblique scraping component 34 at one end close to and away from the adjacent rolling cylinder 2 side wall.

[0036] The movable scraping part 3 is used to scrape the part including the rolling roller 213 and the inclined inner wall of the rolling cylinder 2, so that the energy-saving paint calcined raw materials adhered to the rolling roller 213 are scraped off by the roller wall scraping part 32, and the energy-saving paint calcined raw materials adhered to the inclined inner wall of the rolling cylinder 2 are fully scraped off by cooperating with the No. 1 oblique scraping part 33 and the No. 2 oblique scraping part 34, thereby increasing the utilization rate of the energy-saving paint calcined raw materials, and at the same time, the roller wall scraping part 32, the No. 1 oblique scraping part 33 and the No. 2 oblique scraping part 34 are driven to scrape by transmitting the power of the rolling component 21 by the transmission structure, thereby reducing the power source and saving cost.

[0037] Specifically, firstly, the energy-saving paint calcined raw material is poured into the rolling drum 2 from the feed inlet, and then the two No. 1 motors 211 are controlled to drive the rolling rollers 213 to rotate. At this time, the rolling roller 213 on the left rotates clockwise and the rolling roller 213 on the right rotates counterclockwise, so that the energy-saving paint calcined raw material located between the two rolling rollers 213 is rolled and crushed, and as the rolling rollers 213 rotate, the horizontal section on the front side of the U-shaped synchronous rod 312 and the connecting rod 311 form a crank connection. Rod structure, thereby driving the U-shaped synchronization rod 312 to reciprocate left and right, and under the action of the transmission rod 313, driving the roller wall scraping component 32 to swing left and right and scrape the energy-saving coating calcined raw materials on the side wall of the rolling roller 213, and as the roller wall scraping component 32 swings left and right, the No. 1 oblique scraping component 33 and the No. 2 oblique scraping component 34 will perform oblique reciprocating motion along the inclined inner wall of the rolling cylinder 2, thereby scraping the inclined inner wall of the rolling cylinder 2, and mixing it by the mixing component 22.

[0038] See also Figure 4 , Figure 5 and Figure 7 The roller wall scraping component 32 includes an arc-shaped rotating plate 321 hinged at the right end of the transmission rod 313, and a plurality of scraping strips 322 are evenly arranged on the inner arc surface of the arc-shaped rotating plate 321. Leakage grooves are arranged on the arc-shaped rotating plate 321 and between two scraping strips 322; arc-shaped grooves 323 are arranged on the front and rear inner walls of the rolling cylinder 2 corresponding to the positions of the arc-shaped rotating plate 321, and limiting sliding rods 324 are fixed on the front and rear sides of the arc-shaped rotating plate 321 and corresponding to the positions of the arc-shaped grooves 323.

[0039] The roller wall scraping component 32 is used to scrape off the energy-saving paint calcined raw materials adhered to the side wall of the rolling roller 213, mainly by the scraping bar 322 swinging back and forth along the arc-shaped rotating plate 321, and at the same time, it can make the energy-saving paint calcined raw materials scraped by the scraping bar 322 leak from the leakage groove to the position of the mixing component 22, and facilitate the mixing component 22 to mix the energy-saving paint calcined raw materials.

[0040] Continue reading Figure 4 , Figure 5 and Figure 7 The No. 1 oblique scraping component 33 includes an outer rod 331 symmetrically fixed to the left end of the bottom of the arc-shaped rotating plate 321, a sliding square rod 332 is slidably connected inside the outer rod 331, and a scraper 333 is hinged at the bottom of the two sliding square rods 332; limiting grooves are set on the front and rear inner walls of the rolling cylinder 2 corresponding to the position of the scraper 333, and square sliders 334 are fixed on the front and rear sides of the scraper 333 and corresponding to the position of the limiting grooves.

[0041] Continue reading Figure 4 , Figure 5 and Figure 7The second oblique scraping component 34 includes a square sleeve rod 341 fixed to the right end of the bottom of the arc-shaped rotating plate 321, and an embedded square rod 342 is slidably connected inside the square sleeve rod 341. A mounting frame 343 is fixed to the bottom of the embedded square rod 342, and a shovel plate 344 is rotatably mounted on the mounting frame 343. A torsion spring is provided at the rotation position of the shovel plate 344 and the mounting frame 343; oblique sliding grooves are provided on the front and rear inner walls of the rolling cylinder 2 and at the position corresponding to the mounting frame 343. The oblique sliding grooves are further away from the oblique side walls of the rolling cylinder 2 than the limiting sliding grooves, and limiting sliding blocks 345 are fixed on the front and rear sides of the mounting frame 343 and at the positions corresponding to the oblique sliding grooves.

[0042] In this embodiment, if Figure 5 and Figure 6 As shown, in order to enable the shovel plate 344 to lift the scooped energy-saving paint calcined raw materials, a pressure slope is arranged on the inclined inner wall of the rolling cylinder 2 near the mixing component 22. In addition, in order to prevent the shovel plate 344 from moving to the position of the energy-saving paint calcined raw materials scraped by the scraper 333 and pushing them so that they cannot be shoveled away, a movable plate is arranged on the inclined inner wall of the rolling cylinder 2. The movable plate is connected by two elastic telescopic rods that are telescoped at the inclined inner wall of the rolling cylinder 2, and the front and rear sides of the shovel plate 344 are provided with track rods 346 that cooperate with the movable plate, and the position of the movable plate close to the pressure slope is against the pressure slope.

[0043] The No. 1 oblique scraping component 33 and the No. 2 oblique scraping component 34 are used in combination to scrape off the energy-saving paint calcined raw materials adhered to the inclined inner wall of the rolling cylinder 2. The No. 1 oblique scraping component 33 and the No. 2 oblique scraping component 34 are used for segmented scraping, so that the inclined inner wall of the rolling cylinder 2 can be fully scraped, thereby improving the utilization rate of the energy-saving paint calcined raw materials, and the scraped energy-saving paint calcined raw materials can also be scooped up by the No. 2 oblique scraping component 34, so that it is more convenient for the mixing component 22 to mix the energy-saving paint calcined raw materials.

[0044] Specifically, as the U-shaped synchronization rod 312 drives the transmission rod 313 to reciprocate left and right, the arc-shaped rotating plate 321 will swing back and forth left and right under the cooperation of the limiting slide rod 324 and the arc-shaped groove 323, so that the scraper bar 322 can continuously scrape off the energy-saving paint calcined raw materials adhered to the side wall of the rolling roller 213, and the scraped energy-saving paint calcined raw materials will leak from the leakage groove to the bottom.

[0045] When the arc-shaped rotating plate 321 swings left and right, the square sleeve rod 341 will drive the outer sleeve rod 331, the sliding square rod 332 and the embedded square rod 342 to move back and forth left and right, and through the cooperation of the square slider 334 and the limiting slide groove and the oblique slide groove and the limiting slider 345, the scraper 333 and the shovel plate 344 can always fit the inclined inner wall of the rolling cylinder 2, so that the scraper 333 and the shovel plate 344 can scrape off the energy-saving paint calcined raw materials adhered to the inclined inner wall of the rolling cylinder 2 in a reciprocating manner, and the scraper 333 can push the energy-saving paint calcined raw materials away from the shovel plate 344 to the position of the shovel plate 344 and shovel them to the position of the mixing component 22 together with the shovel plate 344.

[0046] When the shovel plate 344 moves toward the pressing slope, the shovel plate 344 will press against the inclined inner wall of the rolling cylinder 2 due to the action of the torsion spring, and the track rod 346 will move under the moving plate until the shovel plate 344 moves to the pressing slope position, at which time the track rod 346 will push the moving plate upward, and due to the pressing slope, the shovel plate 344 will lift the energy-saving paint calcined raw materials. Thereafter, when the shovel plate 344 moves away from the pressing slope, the track rod 346 will be pressed by the moving plate and move above the moving plate, thereby lifting the shovel plate 344. When the shovel plate 344 moves to the position farthest from the pressing slope, the track rod 346 will detach from the moving plate. At this time, the shovel plate 344 will press against the inclined inner wall of the rolling cylinder 2 again due to the action of the torsion spring, thereby shoveling the energy-saving paint calcined raw materials.

[0047] See also Figure 2 and Figure 5 The mixing assembly 22 includes a central shaft 221 rotatably mounted between the front and rear walls of the rolling cylinder 2, and a plurality of circular array toggle plates 222 are linearly and evenly arranged on the central shaft 221. The front end of the central shaft 221 passes through the rolling cylinder 2, and a limiting shaft 223 is fixed at the front end of the central shaft 221. A transmission belt 224 is connected between the limiting shaft 223 and the rotating shaft 212. The mixing assembly 22 is used to break up the energy-saving coating calcined raw materials entering the discharge port 23. Therefore, the mixing assembly 22 can not only mix and break up the energy-saving coating calcined raw materials scraped by the first oblique scraping component 33, the second oblique scraping component 34 and the roller wall scraping component 32, but also directly mix and break up the energy-saving coating calcined raw materials directly falling from the rolling assembly 21, thereby making the energy-saving coating calcined raw materials mixed evenly, increasing the effect of calcination on the reaction of the energy-saving coating calcined raw materials, and at the same time, the mixing assembly 22 also provides power through the rolling assembly 21, thereby further reducing the power source and saving costs.

The feeding part 4 is used to further rotate and scatter the energy-saving paint calcining raw materials falling from the discharge port 23, and can quickly and evenly sprinkle the mixed energy-saving paint calcining raw materials into the calcining furnace, and the blocking plate 411 and the feeding barrel 41 cooperate with the closing plate 1 to make the calcining furnace in a closed state, thereby reducing the flying of the powdered energy-saving paint calcining raw materials.

[0049] Specifically, as the two No. 1 motors 211 drive the rolling rollers 213 to rotate, the central shaft 221 will rotate under the transmission action of the transmission belt 224, and the fallen energy-saving paint calcined raw materials will be scattered through the toggle plate 222, and the mixed energy-saving paint calcined raw materials will fall from the discharge port 23 into the feeding barrel 41, and the synchronous belt 424 will be driven to rotate by the No. 2 motor 421, so that the feeding barrel 41 will rotate, and the energy-saving paint calcined raw materials located inside it will be further mixed evenly. After mixing, the energy-saving paint calcined raw materials will fall out from the bottom of the feeding barrel 41.

[0050] See also Figure 8 and Fig. 9 The cleaning part 5 includes an L-shaped mounting rod 51 fixed to the bottom of the feed barrel 41, and a guide component 52 and a furnace wall scraping component 53 are sequentially arranged on the L-shaped mounting rod 51 from the middle to the outside; the guide component 52 includes a collective mounting shaft 521 fixed to the non-vertical section of the L-shaped mounting rod 51 and one end close to the inner wall of the calcining furnace, and a rotating sleeve 522 is rotatably installed on the collective mounting shaft 521 at a position close to the feed barrel 41, and a plurality of turn plates 523 are evenly arranged on the rotating sleeve 522 and at a position close to the feed barrel 41; a plurality of arc-shaped friction plates 524 for driving the rotating sleeve 522 to rotate by friction are evenly fixed at the bottom of the closing plate 1 and at a position corresponding to the rotating sleeve 522.

[0051] The cleaning part 5 can not only scrape the energy-saving coating calcined raw materials from the furnace wall of the calcining furnace, but also guide the energy-saving coating calcined raw materials falling from the bottom of the feeding tube 41 through the guide component 52, and drive the rotating sleeve 522 to rotate through the arc friction plate 524, so that the energy-saving coating calcined raw materials are knocked down into the calcining furnace by the turn plate 523, and this knocking down method can further prevent the powdered energy-saving coating calcined raw materials from flying.

[0052] See also Figure 1 , Figure 8 and Fig. 9 The furnace wall scraping component 53 includes an arc-shaped collecting plate 531 fixed on one end of the collecting installation shaft 521 close to the inner wall of the calcining furnace, the arc-shaped collecting plate 531 is close to the arc surface of the inner wall of the calcining furnace and is symmetrically fixed with multiple vertical scraping blocks 532 on both sides of the collecting installation shaft 521, the arc-shaped collecting plate 531 is close to the arc surface of the inner wall of the calcining furnace and is located at the collecting installation shaft 521. The movable arc plate 533 is vertically and linearly connected to the arc surface of the inner wall of the calcining furnace, and multiple horizontal scraping blocks 534 are evenly arranged vertically on the arc surface of the movable arc plate 533 close to the inner wall of the calcining furnace; the inner wall of the calcining furnace is provided with a coordination groove for driving the movable arc plate 533 to move up and down, and the movable arc plate 533 is fixed with a coordination rod 535 matching the coordination groove close to the inner wall of the calcining furnace.

[0053] The furnace wall scraping component 53 is used to scrape the furnace wall of the calcining furnace, so as to scrape off the energy-saving coating calcining raw materials adhered to the furnace wall. At the same time, it can also scrape in a combined manner of a vertically moving horizontal scraper block 534 and a vertical scraper block 532 rotating around the calcining furnace wall, thereby increasing the scraping effect of the calcining furnace wall, thereby further improving the utilization rate of the energy-saving coating calcining raw materials and saving costs.

[0054] Specifically, when the energy-saving coating calcined raw materials fall from the feeding barrel 41 into the calcining furnace, the rotating sleeve 522 rotates due to the friction with the arc friction plate 524, and drives the dial plate 523 to knock down the energy-saving coating calcined raw materials, and the vertical scraper block 532 will continue to scrape the energy-saving coating calcined raw materials attached to the inner wall of the calcining furnace and drop them to the bottom of the calcining furnace. At the same time, the combined action of the coordination rod 535 and the coordination groove makes the movable arc plate 533 move back and forth up and down, so that the horizontal scraper block 534 scrapes off the energy-saving coating calcined raw materials attached to the furnace wall of the calcining furnace while rotating with the feeding barrel 41.

[0055] The working steps of the present invention are as follows: the first step is to pour the energy-saving paint calcined raw materials into the rolling drum 2 from the feed port, and then control the two No. 1 motors 211 to drive the rolling rollers 213 to rotate. At this time, the rolling roller 213 on the left rotates clockwise and the rolling roller 213 on the right rotates counterclockwise, so that the energy-saving paint calcined raw materials located between the two rolling rollers 213 are rolled and crushed.

[0056] In the second step, as the rolling roller 213 rotates, a crank-connecting rod structure is formed under the action of the horizontal section on the front side of the U-shaped synchronization rod 312 and the connecting rod 311, thereby driving the U-shaped synchronization rod 312 to reciprocate left and right, and under the action of the transmission rod 313, the roller wall scraping component 32 is driven to swing left and right and scrape the energy-saving paint calcination raw materials on the side wall of the rolling roller 213, and as the roller wall scraping component 32 swings left and right, the No. 1 oblique scraping component 33 and the No. 2 oblique scraping component 34 will perform an oblique reciprocating motion along the inclined inner wall of the rolling cylinder 2, thereby scraping the inclined inner wall of the rolling cylinder 2.

[0057] In the third step, when the energy-saving paint calcined raw materials fall from the rolling drum 2 to the mixing component 22 position, as the two No. 1 motors 211 drive the rolling rollers 213 to rotate, the middle shaft 221 will rotate under the transmission action of the transmission belt 224, and the fallen energy-saving paint calcined raw materials will be scattered through the toggle plate 222, and the mixed energy-saving paint calcined raw materials will fall from the discharge port 23 into the feeding drum 41, and the synchronous belt 424 will be driven to rotate by the No. 2 motor 421, so that the feeding drum 41 will rotate, and the energy-saving paint calcined raw materials located inside it will be further mixed evenly. After mixing, the energy-saving paint calcined raw materials will fall out from the bottom of the feeding drum 41.

[0058] In the fourth step, when the energy-saving coating calcined raw materials fall from the feeding tube 41 into the calcining furnace, the rotating sleeve 522 rotates due to the friction with the arc friction plate 524, and drives the dial plate 523 to knock down the energy-saving coating calcined raw materials, and the vertical scraper block 532 will continue to scrape the energy-saving coating calcined raw materials attached to the inner wall of the calcining furnace and drop them to the bottom of the calcining furnace. At the same time, the combined action of the coordination rod 535 and the coordination groove makes the movable arc plate 533 move back and forth up and down, so that the horizontal scraper block 534 can scrape off the energy-saving coating calcined raw materials attached to the wall of the calcining furnace while rotating with the feeding tube 41.
