Description

Technical Field

[0001] This utility model relates to the field of steam boiler technology, specifically a steam boiler that is easy to feed coal into. Background Technology

[0002] A boiler is an energy conversion device. The energy input into a boiler can be in the form of chemical energy from fuel, electrical energy, or thermal energy from high-temperature flue gas. After conversion by the boiler, steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy are output. A search revealed a steam boiler with publication number CN219894084U that is easy to clean. The boiler includes a sterilization chamber, a steam boiler fixedly connected to its outer surface, and a steam duct on the outer surface of the steam boiler. The steam duct is connected to the sterilization chamber via branch pipes, and a filter screen is fixedly connected to the inner cavity of each branch pipe. A condenser pipe is connected to the upper surface of the sterilization chamber. Sliding frames are fixedly connected to the inner cavities of the sterilization chamber, and mesh steam racks are movably connected to the inner cavities of the sliding frames. A scraper is movably connected to the inner cavities of the sterilization chamber. This technical solution solves the problem in related technologies where steam boilers leave moisture and fine impurities on the inner walls after use, requiring workers to crawl inside the sterilization chamber to wipe them, especially in crevices and nooks, which is time-consuming and laborious, hindering quick cleaning of the boiler's inner walls and improving the practicality of the device. However, this solution is not convenient for fuel supply. Therefore, we provide a steam boiler that facilitates coal feeding. Utility Model Content

[0003] To address the above technical problems, this utility model provides a steam boiler that facilitates coal feeding.

[0004] To solve the above-mentioned technical problems, the present invention provides a steam boiler that facilitates coal feeding, comprising a base, a combustion boiler fixedly installed at the top of the base, a fuel assembly for transmitting fuel installed at the top of the base, the fuel assembly including a support column fixedly installed at the top of the base, a first motor fixedly installed on the surface of the support column, an air pump fixedly installed at the top of the base on the side of the combustion boiler, a rotating shaft fixedly installed at the output end of the first motor located between the support columns, a rotating roller fixedly installed on the outer side of the rotating shaft, and a conveyor belt sleeved on the outer side of the rotating roller.

[0005] Furthermore, a feeding assembly is installed on the side of the combustion boiler where the fuel assembly is located. The feeding assembly includes a feeding box fixedly installed on the surface of the combustion boiler, and a gate is movably installed inside the feeding box.

[0006] Furthermore, an electric push rod is fixedly installed on the inner wall of the combustion boiler at the top of the gate, and a discharge port is opened on one side of the feed box.

[0007] Furthermore, a combustion conveying assembly is installed inside and on the surface of the combustion boiler. The combustion conveying assembly includes a second motor fixedly installed on the surface of the combustion boiler. The output end of the second motor is located inside the combustion boiler and a conveying shaft is fixedly installed thereon. A conveying roller is fixedly installed on the outside of the conveying shaft.

[0008] Furthermore, a metal conveyor belt is fitted around the outer side of the conveyor roller, and a slag baffle is fixedly installed inside the combustion boiler on the side of the metal conveyor belt. A waste bin is fixedly installed below the slag baffle at the top of the base.

[0009] Furthermore, a steam assembly is installed inside the combustion boiler. The steam assembly includes a water inlet pipe fixedly installed inside the combustion boiler, and a heating pipe is fixedly installed at the end of the water inlet pipe.

[0010] Furthermore, a drain pipe is fixedly installed at the end of the heating tube, a steam collecting pipe is fixedly installed at the top of the heating tube, and a steam transmission pipe is fixedly installed at the top of the steam collecting pipe.

[0011] This utility model has the following advantages compared with the prior art:

[0012] 1. This utility model uses a first motor to drive a rotating shaft and rotating rollers to rotate, thereby driving a conveyor belt to move. Coal is moved along the conveyor belt to its highest point and then falls into the feed hopper. This continuous and automatic feeding process eliminates the need for workers to frequently shovel coal into the furnace, greatly reducing labor intensity and ensuring a stable coal supply. An electric push rod controls the opening and closing of the gate, allowing coal to enter the combustion boiler through the discharge port. The gate controls the height of the coal bed, and by adjusting the height of the coal bed, the rate at which coal enters the boiler is controlled.

[0013] 2. This utility model uses a second motor to drive the transmission shaft to rotate, which in turn moves the transmission rollers and the metal conveyor belt. Coal can be burned on the metal conveyor belt, and the residue after combustion enters the interior of the waste bin through the slag baffle. The continuous combustion process makes the coal burn more completely, improves the thermal efficiency of the boiler, and saves fuel. Water is added to the interior of the heating tube through the water inlet pipe, and the high-temperature flue gas heats the heating tube, so that some of the water turns into water vapor and enters the steam transmission pipe from the steam collection pipe for collection. The stable firebed ensures the stability of steam production and pressure, which is beneficial to the operation of subsequent steam-using equipment. Attached Figure Description

The opening and closing state of the gate 42 is controlled by the electric push rod 43, so that coal enters the combustion boiler 3 through the discharge port 44. The height of the coal bed is controlled by the gate 42. By adjusting the height of the coal bed, the rate at which coal enters the boiler is controlled.

[0024] The combustion boiler 3 is equipped with a combustion conveying assembly 5 inside and on its surface. The combustion conveying assembly 5 includes a second motor 51 fixedly installed on the surface of the combustion boiler 3. The output end of the second motor 51 is located inside the combustion boiler 3 and a conveying shaft 52 is fixedly installed thereon. A conveying roller 53 is fixedly installed on the outside of the conveying shaft 52.

[0025] A metal conveyor belt 54 is fitted around the outer side of the conveyor roller 53. A slag baffle 55 is fixedly installed inside the combustion boiler 3 on the side of the metal conveyor belt 54. A waste bin 56 is fixedly installed below the slag baffle 55 at the top of the base 1. A second motor 51 drives the conveyor shaft 52 to rotate, which in turn drives the conveyor roller 53 and the metal conveyor belt 54 to move. The conveyor belt 54 is made of high-temperature resistant material. Coal can be burned on the metal conveyor belt 54. The residue after combustion enters the interior of the waste bin 56 through the slag baffle 55. The continuous combustion process makes the coal burn more completely, improves the thermal efficiency of the boiler, and saves fuel.

[0026] The combustion boiler 3 is equipped with a steam assembly 7, which includes a water inlet pipe 71 fixedly installed inside the combustion boiler 3, and a heating pipe 72 fixedly installed at the end of the water inlet pipe 71.

[0028] The working process of this embodiment is as follows:

[0029] In operation, the first motor 22 on the support column 21 is started. The first motor 22 drives the rotating shaft 23 and the rotating roller 24 to rotate, thereby driving the conveyor belt 25 to move. The coal to be added is placed on the conveyor belt 25. After the coal moves to the highest point through the conveyor belt 25, it falls into the feed box 41. The opening and closing state of the gate 42 is controlled by the electric push rod 43, so that the coal enters the combustion boiler 3 through the discharge port 44. The height of the coal bed is controlled by the gate 42. By adjusting the height of the coal bed, the rate at which coal enters the boiler is controlled. The second motor 51 drives the conveyor shaft 52 to rotate, thereby driving the conveyor roller 53 and the feed box 41 to rotate. The metal conveyor belt 54 moves, and coal can be burned on the metal conveyor belt 54. The residue after combustion enters the interior of the waste box 56 through the ash baffle 55. Air is added to the interior of the combustion boiler 3 by the air pump 6. The air moves from below to above the metal conveyor belt 54. During this process, the lower temperature air cools the lower metal conveyor belt 54, thereby ensuring the normal operation of the metal conveyor belt 54 and participating in the combustion reaction. Water is added to the interior of the heating pipe 72 through the water inlet pipe 71. The high temperature flue gas heats the heating pipe 72, so that some of the water turns into water vapor and enters the steam transmission pipe 75 from the steam collection pipe 74 for collection.
