Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, and in particular to a device for cleaning blockages and impurities in heating furnaces. Background Technology

[0002] Currently, most of the drying equipment in pulverized coal workshops uses heating furnaces that burn blast furnace gas. The main purpose is to use the high-temperature flue gas generated by burning blast furnace gas to mix with waste flue gas to form a drying medium. The temperature of the drying medium is mainly adjusted by controlling the amount of waste flue gas added or the amount of gas burned in the heating furnace. The drying medium entering the mill should be controlled within 250-350°C. With the development of the market, some enterprises have pulverizing workshops located in areas where there is no gaseous fuel such as blast furnace gas.

[0003] The impurities formed during combustion in the existing heating furnace cannot be cleaned in time, leading to blockages that affect the furnace's lifespan and normal operation. Impurities and some unburned raw materials will form clumps in the heating furnace, causing blockages that are difficult to clean, indicating room for improvement.

[0004] Therefore, this application proposes a device for cleaning blockages and impurities in a heating furnace to solve the problems in the prior art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for cleaning blockages and impurities in a heating furnace.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for cleaning blockages and impurities in a heating furnace includes a discharge pipe installed on the heating furnace and a base plate;

[0008] Two brackets are fixedly connected to the base plate, and the same waste discharge pipe is fixedly installed on the two brackets. A circular tube is rotatably connected inside the waste discharge pipe, and a spiral plate is fixedly connected to the circular tube. The spiral plate is adapted to the waste discharge pipe, and a steel brush is fixedly installed on the spiral plate. The steel brush is in contact with the inner side of the waste discharge pipe. Multiple sleeves are sealed to the circular tube, and piston rods are slidably connected inside each of the multiple sleeves. One end of each of the multiple piston rods is fixedly connected to the same scraper, which corresponds to the inner side of the waste discharge pipe. Through the coordinated design of the waste discharge pipe, circular tube, spiral plate, steel brush, sleeves, piston rods, scraper, motor, liquid pump, and control panel, the inner side of the waste discharge pipe can be cleaned in multiple stages under the coordinated drive of the motor and liquid pump, improving convenience and the service life of the equipment.

[0009] Specifically, the spiral plate has a groove that is adapted to the scraper and is used to store the scraper.

[0010] Specifically, a support plate is fixedly installed on the base plate, and a motor is fixedly installed on the support plate. A gear is fixedly connected to the output end of the motor. A gear ring is fixedly fitted on one end of the round tube. The gear ring meshes with the gear. Driven by the motor, the gear rotates and meshes with the gear ring, thereby causing the gear ring to drive the round tube to rotate on the waste discharge pipe. At the same time, the spiral plate rotates inside the waste discharge pipe, and the spiral plate drives the steel brush to rotate. At this time, through the action of the spiral plate and the steel brush, the impurities in the waste discharge pipe can be pushed to the discharge pipe fitting at one end of the waste discharge pipe, thereby achieving preliminary cleaning of the waste discharge pipe.

[0011] Specifically, a connecting pipe is installed at one end of the circular tube, and a liquid pump is fixedly installed on the support plate. One end of the connecting pipe is sealed to the liquid pump. Through the reverse drive of the liquid pump and the cooperation of the connecting pipe, the hydraulic fluid in the circular tube can be extracted and transported to the storage tank.

[0012] Specifically, a sealing bearing is fixedly sleeved on one end of the connecting pipe. The outer wall of the sealing bearing is fixedly connected to the round pipe. The sealing bearing facilitates the rotation of the round pipe and prevents hydraulic oil leakage inside the round pipe.

[0013] Specifically, a control panel is fixedly installed on the support plate, and the liquid pump and motor are both connected to the control panel. The motor and liquid pump are driven and controlled by a preset program in the control panel.

[0014] Specifically, a second sealed bearing is fixedly sleeved on the circular tube, and the outer wall of the second sealed bearing is fixedly connected to the discharge pipe. A discharge pipe is sealed to the bottom of the discharge pipe to facilitate the rotation of the circular tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model discloses a heating furnace blockage and impurity cleaning device. Through the coordinated design of the discharge pipe, round pipe, spiral plate, steel brush, sleeve, piston rod, scraper, motor, liquid pump and control panel, the device can achieve multi-stage cleaning of the inner side of the discharge pipe under the coordinated drive of the motor and liquid pump, thereby improving convenience and service life of the equipment.

[0024] Reference Figures 1-4 A device for cleaning blockages and impurities in a heating furnace includes a discharge pipe 3 and a base plate 1 installed on the heating furnace.

[0025] Two brackets 2 are fixedly connected to the base plate 1. A common waste discharge pipe 3 is fixedly installed on both brackets 2. A circular pipe 4 is rotatably connected inside the waste discharge pipe 3. A spiral plate 5 is fixedly connected to the circular pipe 4, and the spiral plate 5 is adapted to the waste discharge pipe 3. A steel brush 6 is fixedly installed on the spiral plate 5, and the steel brush 6 contacts the inner side of the waste discharge pipe 3. Multiple sleeves 7 are sealed and connected to the circular pipe 4. The multiple sleeves 7 are arranged at equal intervals on the circular pipe 4. A piston rod 8 is slidably connected inside each of the multiple sleeves 7, and a sealing sleeve is fixedly fitted at one end of each of the multiple piston rods 8. Multiple sealing rings are slidably connected to multiple sleeves 7, and one end of multiple piston rods 8 is fixedly connected to the same scraper 9. The scraper 9 corresponds to the inner side of the discharge pipe 3. Through the cooperative design between the discharge pipe 3, round pipe 4, spiral plate 5, steel brush 6, sleeve 7, piston rod 8, scraper 9, motor 11, liquid pump 13 and control panel 15, the inner side of the discharge pipe 3 can be cleaned in multiple stages under the cooperative drive between the motor 11 and the liquid pump 13, which improves convenience and service life of the equipment.

[0026] In this embodiment, a groove is provided on the spiral plate 5, which is adapted to the scraper 9 and is used to store the scraper 9. One end of the waste discharge pipe 3 is fixedly connected to a flange, which facilitates the connection of the waste discharge pipe 3 to the waste discharge port on the heating furnace. The bottom of the waste discharge pipe 3 is sealed with a discharge pipe, and a valve is installed on the discharge pipe to discharge the cleaned waste.

[0027] In this embodiment, a support plate 10 is fixedly installed on the base plate 1, and a motor 11 is fixedly installed on the support plate 10. A gear is fixedly connected to the output end of the motor 11. A toothed ring 12 is fixedly sleeved on one end of the round tube 4. The toothed ring 12 is meshed with the gear. Driven by the motor 11, the gear rotates and meshes with the toothed ring 12, thereby causing the toothed ring 12 to drive the round tube 4 to rotate on the discharge pipe 3. At the same time, it drives the spiral plate 5 to rotate inside the discharge pipe 3. Simultaneously, the spiral plate 5 drives the steel brush 6 to rotate. At this time, through the action of the spiral plate 5 and the steel brush 6, the impurities in the discharge pipe 3 can be pushed to the discharge pipe at one end of the discharge pipe 3, thereby achieving preliminary cleaning of the discharge pipe 3.

[0028] In this embodiment, a connecting pipe 14 is installed at one end of the circular tube 4, and a liquid pump 13 is fixedly installed on the support plate 10. One end of the connecting pipe 14 is sealed to the liquid pump 13. Under the reverse drive of the liquid pump 13 and the cooperation of the connecting pipe 14, the hydraulic fluid in the circular tube 4 can be extracted and transported to the storage tank.

[0029] In this embodiment, a sealing bearing is fixedly sleeved on one end of the connecting pipe 14. The outer wall of the sealing bearing is fixedly connected to the round pipe 4. The sealing bearing facilitates the rotation of the round pipe 4 and prevents hydraulic oil leakage inside the round pipe 4.

[0030] In this embodiment, a control panel 15 is fixedly installed on the support plate 10. The liquid pump 13 and the motor 11 are both connected to the control panel 15. The motor 11 and the liquid pump 13 are driven and controlled by the preset program in the control panel 15.

[0031] In this embodiment, a sealed bearing 2 is fixedly sleeved on the circular tube 4. The outer wall of the sealed bearing 2 is fixedly connected to the discharge pipe 3. The bottom of the discharge pipe 3 is sealed with a discharge pipe to facilitate the rotation of the circular tube 4.

[0032] Working principle: When in use, first connect the power supply and drive the motor 11 and the liquid pump 13 through the preset program in the control panel 15;

[0033] Driven by the electric motor 11, the gear rotates and meshes with the gear ring 12, which in turn drives the round tube 4 to rotate on the waste discharge pipe 3. At the same time, the spiral plate 5 rotates inside the waste discharge pipe 3, and the spiral plate 5 drives the steel brush 6 to rotate. At this time, through the action of the spiral plate 5 and the steel brush 6, the impurities in the waste discharge pipe 3 can be pushed to the discharge pipe fitting at one end of the waste discharge pipe 3, thereby achieving the initial cleaning of the waste discharge pipe 3.

[0034] At the same time, the steel brush 6 can achieve the effect of cleaning the complex impurities inside the discharge pipe 3 in the second step.

[0035] When it is necessary to clean the clumps that are difficult to brush off the inside of the discharge pipe 3, the hydraulic oil in the storage tank can be drawn out by the hydraulic pump 13 and transported to the round pipe 4 through the connecting pipe 14. During this process, the pressure inside the round pipe 4 gradually increases. At the same time, under the action of the pressure, multiple piston rods 8 slide in the sleeve 7 and extend outward a certain distance. Meanwhile, multiple piston rods 8 drive the scraper 9 to move and make the scraper 9 contact the inside of the discharge pipe 3. At this time, under the drive of the motor 11 and the cooperation and transmission between the round pipe 4, multiple sleeves 7 and multiple piston rods 8, the scraper 9 can effectively scrape off and clean the clumps attached to the inside of the discharge pipe 3.

[0036] Subsequently, the hydraulic fluid inside the circular tube 4 can be extracted and transported to the storage tank by the reverse drive of the hydraulic pump 13 and the cooperation of the connecting pipe 14. During this process, a negative pressure will be generated inside the circular tube 4. Under the action of the negative pressure, multiple piston rods 8 will be retracted into multiple sleeves 7 respectively, and the scraper 9 will be disengaged from the discharge pipe 3 and moved into the groove on the spiral plate 5. This will reduce the wear on the inner side of the discharge pipe 3 and the scraper 9 and improve the service life.

[0037] The technological advancement of this invention compared to the prior art is that the cooperation of various components can achieve the effect of multi-stage cleaning of the discharge pipe 3, avoiding blockage of the discharge pipe 3, and the structure is simple and more practical.
