[0003] The existing coal desulfurization device cannot evenly mix the desulfurization powder into the coal, thereby reducing the desulfurization effect during coal combustion. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems in the existing technology and propose a coal sulfur fixation and dust removal device.

[0008] Furthermore, a spring telescopic rod is hingedly provided on the grinding rod, and the spring telescopic rod is hingedly connected to the rotating tube. The spring telescopic rod can enable the grinding rod to maintain a certain angle with the rotating tube.

[0009] Furthermore, the rotating tube is connected to the loading block with a connecting spring rod, the slot block is fixedly provided on the lower side of the loading chamber, four grooves are fixedly provided on the upper side of the loading block, six trapezoidal blocks are fixedly provided on the lower side of the loading block, and six reverse trapezoidal blocks are fixedly provided on the inner side of the slot block. The gap between the trapezoidal block of the loading block and the trapezoidal block of the slot block is matched, and during the rotation of the loading block, the trapezoidal block of the loading block will slide on the trapezoidal block of the slot block, so that the loading block slides back and forth up and down, so that the solid sulfur powder is intermittently discharged through the grooves on the loading block.

[0010] Furthermore, dust removal chambers are opened on both sides of the shell, and the dust removal chamber is connected with the combustion chamber through a channel. A dust removal brush is slidably provided in the dust removal chamber, a dust removal rod is fixedly provided on the upper side of the dust removal brush, the dust removal rod is slidably connected to the shell, and a dust removal spring is provided on the dust removal rod connected to the shell, a collecting block is fixedly provided on the lower side of the dust removal chamber, and a filter is provided on the side wall of the dust removal chamber.

[0011] Furthermore, a feed port is provided on the upper side of the shell, a disassembly plate is fixedly provided on the front side of the shell, a cover plate is hingedly provided on the front side of the disassembly plate, the cover plate is hingedly provided on the rear side of the shell, and a fan is provided on the rear side.

[0012] First, open the cover on the front side, so that the coal enters the device from the through hole on the front side of the device, and burns and releases energy in the combustion chamber, put the solid sulfur powder into the device from the feed port, and store it in the feeding chamber, and start the feeding motor at the same time, so that the feeding motor drives the feeding shaft to rotate, and the feeding shaft drives the rotating tube and the centrifugal tube to rotate, so that the centrifugal tube engages the threaded tube, and the centrifugal tube slides upward, so that the centrifugal tube drives the sliding block to slide upward, and drives the grinding rod to rotate through the spring telescopic rod, so that the grinding head rubs and squeezes the lower side wall of the feeding chamber to grind the solid sulfur powder, so that the solid sulfur powder particles are uniform in size, preventing the solid sulfur powder from blocking the spraying port when spraying, and making the solid sulfur powder easier and more evenly mixed with coal after spraying. This device can make the solid sulfur powder particles uniform in size, prevent the solid sulfur powder from blocking the spraying port when spraying, and make the solid sulfur powder easier and more evenly mixed with coal after spraying.

[0013] As the rotating tube rotates, the loading block is driven to rotate, so that the trapezoidal groove surface of the loading block slides on the trapezoidal groove surface of the groove block, so that the loading block slides up and down, so that the solid sulfur powder is intermittently discharged through the grooves on the loading block, so that the solid sulfur powder is intermittently sprayed on the coal, preventing excessive spraying of solid sulfur powder and waste of solid sulfur powder. This device can make the solid sulfur powder be sprayed on the coal intermittently, preventing excessive spraying of solid sulfur powder and waste of solid sulfur powder.

[0014] After the solid sulfur powder is sprayed, the stirring motor is started, so that the stirring motor drives the stirring shaft to rotate, and the stirrer rotates to stir the coal, so that the solid sulfur powder is evenly mixed in the coal, thereby enhancing the effect of sulfur fixation in coal combustion. This device can evenly mix the solid sulfur powder in the coal, thereby enhancing the effect of sulfur fixation in coal combustion.

[0015] When coal is burned, a large amount of dust is generated. The fan starts and fills the air outside the device into the device, thereby providing oxygen for coal combustion and blowing the dust in the device into the dust removal chamber, increasing the air pressure in the dust removal chamber. The air pressure squeezes the dust removal brush, causing the dust removal brush to slide upward, allowing the gas to filter the dust through the filter and allowing the air to flow out. When the dust removal brush slides upward, it drives the dust removal rod to slide upward and stretches the dust removal spring. After the air flows out, the dust removal spring expands and contracts, causing the dust removal rod to slide downward and the dust removal brush to slide downward, causing the dust removal brush to block the filter, causing the dust removal brush to rub the filter back and forth. After the device stops, the dust removal brush can prevent the gas outside the device from entering the device, thereby protecting the device, and scrape the dust on the filter onto the collecting block, which is convenient for collecting and cleaning dust. This device can filter dust and prevent the gas outside the device from entering the device, thereby protecting the device and facilitating the collection and cleaning of dust.

[0025] like Figure 4 As shown, a spring telescopic rod 35 is hingedly provided on the grinding rod 34 , and the spring telescopic rod 35 is hingedly connected to the rotating tube 36 . The spring telescopic rod 36 can enable the grinding rod 34 to maintain a certain angle with the rotating tube 36 .

[0026] like Figure 4 , Figure 5 As shown, the rotating tube 36 is connected to the feeding block 28 and is provided with a connecting spring rod 27, a groove block 29 is fixedly provided on the lower side of the feeding chamber, four grooves are fixedly provided on the upper side of the feeding block 28, six trapezoidal blocks are fixedly provided on the lower side of the feeding block 28, and six reverse trapezoidal blocks are fixedly provided on the inner side of the groove block 29. The clearance between the trapezoidal blocks of the feeding block 28 and the trapezoidal blocks of the groove block 29 is matched. During the rotation of the feeding block 28, the trapezoidal blocks of the feeding block 28 will slide on the trapezoidal blocks of the groove block 29, so that the feeding block 28 slides back and forth up and down, so that the solid sulfur powder is intermittently discharged through the grooves on the feeding block 28.

[0027] like Figure 1 , Figure 2 As shown, dust removal chambers 37 are opened on both sides of the shell 10, and the dust removal chamber 37 is connected with the combustion chamber 20 through channels. A dust removal brush 14 is slidably provided in the dust removal chamber 37, and a dust removal rod 11 is fixedly provided on the upper side of the dust removal brush 14. The dust removal rod 11 is slidably connected to the shell 10, and a dust removal spring 12 is connected to the dust removal rod 11 and the shell 10. A collecting block 15 is fixedly provided on the lower side of the dust removal chamber 37, and a filter screen 13 is provided on the side wall of the dust removal chamber 37.

[0028] like Figure 1 As shown, a feed port 26 is provided on the upper side of the shell 10, a disassembly plate 17 is fixedly provided on the front side of the shell 10, a cover plate 16 is hingedly provided on the front side of the disassembly plate, a cover plate 16 is hingedly provided on the rear side of the shell 10, and a fan 30 is provided on the rear side of 10.

[0029] First, the front cover 16 is opened to allow the coal to enter the device from the through hole on the front side of the device and to be burned and released in the combustion chamber 20. The solid sulfur powder is put into the device from the feed port 26 and stored in the feeding chamber 18. At the same time, the feeding motor 24 is started to drive the feeding shaft 25 to rotate, so that the feeding shaft 25 drives the rotating tube 36 and the centrifugal tube 31 to rotate, so that the centrifugal tube 31 engages with the threaded tube 38 and slides upward, so that the centrifugal tube 31 drives the sliding block 33 to rotate. The grinding rod 34 is driven to rotate through the spring telescopic rod 35, so that the grinding head 19 rubs and squeezes the lower wall of the feeding chamber 18 to grind the solid sulfur powder, so that the solid sulfur powder particles are uniform in size, preventing the solid sulfur powder from blocking the spraying port during spraying, and making the solid sulfur powder easier and more evenly mixed with the coal after spraying. This device can make the solid sulfur powder particles uniform in size, prevent the solid sulfur powder from blocking the spraying port during spraying, and make the solid sulfur powder easier and more evenly mixed with the coal after spraying.

[0030] As the rotating tube 36 rotates, the loading block 28 is driven to rotate, which will cause the trapezoidal groove surface of the loading block 28 to slide on the trapezoidal groove surface of the groove block 29, so that the loading block 28 slides up and down, so that the solid sulfur powder is intermittently discharged through the groove on the loading block 28, so that the solid sulfur powder is intermittently sprayed on the coal, preventing excessive spraying of solid sulfur powder and waste of solid sulfur powder. This device can make the solid sulfur powder sprayed on the coal intermittently, preventing excessive spraying of solid sulfur powder and waste of solid sulfur powder.

[0031] After the sulfur-fixing powder is sprayed, the stirring motor 23 is started, so that the stirring motor 23 drives the stirring shaft 22 to rotate, and the stirrer 21 rotates to stir the coal, so that the sulfur-fixing powder is evenly mixed in the coal, thereby enhancing the sulfur-fixing effect in the coal combustion. This device can evenly mix the sulfur-fixing powder in the coal, thereby enhancing the sulfur-fixing effect in the coal combustion.

[0032] When coal is burning, a large amount of dust is generated. The fan 30 is started to fill the air outside the device into the device, thereby providing oxygen for the coal combustion, and at the same time, the dust in the device is blown into the dust removal chamber 37, so that the air pressure in the dust removal chamber 37 increases, so that the air pressure squeezes the dust removal brush 14, so that the dust removal brush 14 slides upward, so that the gas passes through the filter screen 13 to filter the dust, and the air flows out. When the dust removal brush 14 slides upward, it drives the dust removal rod 11 to slide upward and stretches the dust removal spring 12. After the air flows out, the dust removal brush 14 is removed. The dust spring 12 is extended and retracted, causing the dust removal rod 11 to slide downward, and the dust removal brush 14 to slide downward, so that the dust removal brush 14 blocks the filter 13, and the dust removal brush 14 reciprocates to rub the filter 13. After the device stops, the dust removal brush 14 can prevent the gas outside the device from entering the device, thereby protecting the device, and scrape the dust on the filter 13 onto the collecting block 15, which is convenient for collecting and cleaning dust. This device can filter dust and prevent the gas outside the device from entering the device, thereby protecting the device and facilitating the collection and cleaning of dust.

[0033] Compared with the existing technology, this coal sulfur fixation and dust removal device has the following advantages:

[0034] The powder particles of the solid sulfur powder can be made uniform, so as to prevent the solid sulfur powder from blocking the spraying port during spraying, and the solid sulfur powder can be mixed with the coal more easily and evenly after spraying.

[0035] The sulfur-fixing powder can be evenly mixed into the coal to enhance the sulfur-fixing effect during coal combustion.

[0036] It can filter dust and prevent gas outside the device from entering the device, thereby protecting the device and facilitating the collection and cleaning of dust.
