Description

Technical Field

[0001] The utility model relates to the technical field of hot blast stoves, in particular to a hot blast stove that is easy to burn and clean. Background Art

[0002] Hot air furnaces, as a type of thermal power machinery, began to be widely used in my country in the late 1950s. They have become a replacement for electric heat sources and traditional steam power heat sources in many industries. Through long-term production practice, people have realized that only by using hot air as a medium and carrier can the heat utilization rate and thermal working effect be greatly improved. Traditional electric heat sources and steam heat power are often equipped with multiple circulating fans during the transmission process, so that they ultimately indirectly generate hot air for drying or heating operations.

[0003] Upon investigation, a Chinese patent disclosure disclosed that the utility model relates to the field of machinery (patent number: CN 205050213U), and more specifically, to a hot blast furnace, which includes a frame body, a combustion chamber installed in the frame body and a heat conversion system, and also includes a cleaning device and an air guide system; the heat conversion system is installed on the top of the combustion chamber and is interconnected with the combustion chamber; the air outlet of the air guide system is arranged in the combustion chamber; the cleaning device is installed at the junction of the combustion chamber and the air outlet of the air guide system. The device is novel in design. The setting of the cleaning device can promptly remove the ashes after the combustion of organic matter in the combustion chamber, and the air guide system discharges the remaining ashes through the action of wind force to prevent the accumulation of ashes and affect the combustion effect.

[0004] However, the above technologies often have the following defects:

[0005] After combustion, organic matter may not be completely burned, so that the air guide system cannot effectively discharge the unburned organic matter through the action of wind, resulting in incomplete discharge of waste residue, which in turn affects the subsequent combustion effect. After the combustion process, when discharging the material, the waste residue may adhere to the inner wall of the combustion chamber, making it inconvenient for the staff to clean the waste residue from the inner wall of the combustion chamber, thereby greatly reducing the cleaning efficiency of the staff.

[0006] Therefore, the utility model provides a hot blast stove that is easy to burn and clean, so as to solve the above problems. Utility Model Content

[0038] like Figures 1 to 4 As shown, the utility model provides a hot blast stove that is easy to burn and clean, including a hot blast stove body 1, the hot blast stove body 1 includes a combustion chamber 2 arranged at the bottom, a fire heat converter 3 is arranged above the combustion chamber 2, a knocking assembly 4 is arranged on the outer surface of the combustion chamber 2, and a cleaning assembly 5 is arranged on the lower surface of the combustion chamber 2. The knocking assembly 4 includes a support ring 401 fixedly installed on the outer surface of the combustion chamber 2 through a fixed column, a guide ring 402 is arranged on the upper surface of the support ring 401, a sliding column is slidably connected to the inside of the guide ring 402, a connecting column 403 is fixedly installed on one end of the sliding column, a knocking head 404 is fixedly installed on one end of the connecting column 403, a reset spring 405 is arranged between the connecting column 403 and the guide ring 402, one end of the sliding column is rotatably connected to a hinge seat, a pull rod 406 is fixedly installed on the surface of one side of the hinge seat, and a movable plate is fixedly installed on one end of the pull rod 406 A contact column 412 is fixedly installed on the outer surface of the movable plate, a guide plate is fixedly installed on one side surface of the movable plate, the outer surface of the guide plate is slidably connected to the bottom plate, the bottom plate is fixedly installed on the lower surface of the support ring 401, and the upper surface of the bottom plate is rotatably connected to the driven column, the outer surface of the driven column is fixedly installed with a rotating gear 408, one side of several rotating gears 408 is meshed with a rotating gear ring 409, and the rotating gear ring 409 is rotatably connected to the outer surface of the support ring 401, and a cam 410 is fixedly installed on the top of the driven column, and the cam 410 is located on one side of the contact column 412. A protective frame 411 is provided on the outer surface of the combustion chamber 2, and a drive motor 407 is installed on the lower surface of the protective frame 411 through the shell, and a drive shaft is fixedly installed on the output end of the drive motor 407, and a pulley is provided on the outer surface of the drive shaft and one of the driven columns, and a belt is connected to the outer surface of the pulley for transmission.

[0039] In this embodiment: when it is necessary to clean the inner wall of the combustion chamber 2, the driving motor 407 at the bottom is started to drive the driving shaft to rotate, and the driven column on the other side is driven to rotate through the transmission pulley and belt, and the driven column drives the rotating gear 407 on the outer surface to rotate, and the rotating gear 407 drives the meshing rotating gear ring 409 to rotate, and the rotating gear ring 409 rotates stably on the outer surface of the support ring 401. The rotation of the rotating gear ring 409 causes other meshing rotating gears 408 to rotate synchronously, thereby driving the internal driven column to rotate, and the driven column drives the top cam 410 to rotate, and the protrusion of the cam 410 touches the outer surface of the contact column 412, thereby pushing the contact column 412 and the internal moving plate outward, and the moving plate The pulling rod 406 at one end is driven to move, and the pulling rod 406 drives the sliding column at one end to move through the hinge seat, and the sliding column slides inside the guide ring 402 and causes the return spring 405 to stretch and deform, and the sliding column drives the connecting column 403 at one end and the knocking head 404 away from the outer surface of the combustion chamber 2.

A driving rod is fixedly installed inside the second bevel gear 506, and a second bevel gear 506 is fixedly installed on the outer surface of the driving rod. A first servo motor 507 is provided inside the rotating rod 501, and the output end of the first servo motor 507 is fixedly installed with the driving rod. The outer surface of the rotating rod 501 is rotatably connected to a stabilizing frame, and the stabilizing frame is fixedly installed on the inner side wall of the slag discharge pipe 6. The outer surface of the slag discharge pipe 6 is provided with a second servo motor, and a rotating rod is fixedly installed on the output end of the second servo motor and the bottom of the rotating rod 501. A pulley is provided on the outer surface of the rotating rod, and a belt is connected to the outer surface of the pulley for transmission.

The waste slag can be effectively cleaned. At the same time, the cleaning scraper 503 and the collecting plate 502 can scrape strongly, which can effectively clean the stubbornly adhering waste slag, greatly improving the cleaning quality.

[0048] The staff pours the fuel into the fuel hopper and then inputs it into the feeding pipe 10. The fuel inside the feeding pipe 10 is spirally input into the combustion chamber 2 through the spiral feeder. The setting of the hot air blower 11 inputs the external wind force into the interior of the fire heat converter 3, providing sufficient oxygen to the interior and reducing incomplete fuel production.
