Description

Technical Field

[0001] This utility model relates to the field of furnace chamber technology for heating furnaces, specifically to a furnace chamber structure for industrial heating furnaces that can be quickly cleaned of ash. Background Technology

[0002] The furnace chamber of an industrial heating furnace transfers the heat generated by fuel combustion to the radiant heating surfaces (such as water-cooled walls) around the furnace chamber via radiation. At the same time, it directs the high-temperature flue gas to the furnace outlet, where it is further transferred to the convective heating surfaces.

[0003] Chinese patent CN218821710U discloses a furnace chamber for an oil and gas pipeline station, comprising a furnace chamber body, an air inlet pipe at the top of the furnace chamber body, an air inlet pipe connected to the inlet of a fan, an air outlet pipe connected to the outlet of the fan, and a dust suppression chamber at the other end of the air outlet pipe. The dust suppression chamber contains multiple sets of water spray components, and a water storage tank is connected to the bottom of the dust suppression chamber via a drainage plate. A connecting pipe is connected to one end of the water storage tank, and a water outlet component is connected to the other end of the connecting pipe. The water outlet component connects to the interior of the dust suppression chamber. A limit component is provided on the connecting pipe. The purpose is to reduce dust dispersion through the fusion of water and dust, and to effectively solve the problem of impurities in the water clogging the filter plates by installing or removing them, thereby improving dust suppression efficiency.

[0004] When the local temperature of the furnace tube is too high, the metal will expand due to the high temperature, which will increase the thermal stress. This may cause plastic deformation, which in turn will cause deformation of the furnace chamber. The deformation of the furnace chamber may cause uneven flame distribution, thereby increasing the loss of incomplete combustion. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a furnace structure for industrial heating furnaces that allows for rapid ash removal, thus enabling workers to promptly detect and replace any deformation of the furnace body. To achieve the above objectives, this utility model provides the following technical solution: a furnace chamber structure for an industrial heating furnace that can be quickly cleaned, including a furnace chamber body, mounting rings symmetrically fixed at both ends of the furnace chamber body, deformation measuring components evenly arranged at the outer ends of the two mounting rings, an inner wall cleaning component arranged at the bottom of the furnace chamber body, and a quick cleaning component arranged at the top of the furnace chamber body. The deformation measurement assembly includes connecting rods, each of which is uniformly and fixedly installed on the outer end of the mounting ring, and a limit block is fixedly installed on one end of each connecting rod. A pressure sensor is fixedly installed on the inner side of the limit block, and a sliding plate is in contact with one side of the pressure sensor. A spring is sleeved on the outer end of each connecting rod, and a connecting rod is slidably connected between the outer ends of every two connecting rods.

[0006] Preferably, the inner wall cleaning assembly includes a drive motor, which is fixedly installed at the bottom of the heating furnace. A rotating shaft is fixedly installed at the output end of the drive motor. A main gear is fixedly installed at one end of the rotating shaft. A gear ring is meshed with one side of the main gear. A scraper is fixedly installed on the top of the gear ring.

[0007] Preferably, the rapid ash removal assembly includes a collection head, which is fixedly installed on the top of the furnace body of the heating furnace, and the top of the collection head has a collection groove.

[0008] Preferably, a discharge pipe is fixedly installed on the top of the collection trough, a crushing roller is rotatably connected to the inner wall of the discharge pipe, and a connecting hose is fixedly installed at one end of the discharge pipe.

[0009] Preferably, the two ends of the spring are connected to the limiting plate and the sliding plate respectively, and the inner side of the limiting plate is in contact with the outer end of the furnace body of the heating furnace.

[0010] Preferably, the rotating shaft passes through the inner wall of the heating furnace, the main gear and the gear ring are rotatably connected to the mounting ring, and the scraper is slidably connected to the inner wall of the furnace chamber.

[0011] Preferably, the connecting hose is fixedly connected to the vacuum cleaner, and the collection head penetrates through the top of the furnace body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution uses a deformation measurement component and multiple limiting plates to protect the outer end of the furnace body. When the furnace body deforms, it pushes the limiting plates, which in turn push the springs. The springs then drive the sliding plate to press the pressure sensor. Based on the pressure value received by the pressure sensor, the degree of deformation of the furnace body can be measured. This allows staff to promptly detect and replace the furnace body, ensuring that the fuel and air are fully mixed and preventing incomplete combustion due to localized high temperatures or eddy currents, thus making the heat transfer of the furnace body more stable.

[0013] 2. This solution incorporates an inner wall cleaning component and a rapid ash removal component. The inner wall cleaning component cleans the soot adhering to the inner wall of the furnace body, while the rapid ash removal component cleans and collects the soot from the inner wall of the furnace body, thus making the soot cleaning of the furnace body more thorough and the cleaning process more convenient.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 and Figure 5This utility model provides a technical solution: a furnace chamber structure for a rapidly cleanable industrial heating furnace, comprising a furnace chamber body 1, with mounting rings 2 symmetrically fixed at both ends of the furnace chamber body 1. Deformation measuring components are evenly arranged at the outer ends of the two mounting rings 2. Each deformation measuring component includes connecting rods 31, each connecting rod 31 being evenly fixedly installed at the outer end of the mounting ring 2, and a limiting block 32 being fixedly installed at one end of each connecting rod 31. A pressure sensor 33 is fixedly installed on the inner side of the limiting block 32. The pressure sensor 33 utilizes the piezoresistive effect principle, where the pressure of the measured medium directly acts on the diaphragm (stainless steel or ceramic) of the sensor, causing the diaphragm to produce a micro-displacement proportional to the medium pressure. The pressure sensor 33 is moved, causing a change in the resistance value of the sensor. This change is detected by electronic circuitry and converted into a standard measurement signal corresponding to this pressure. One side of the pressure sensor 33 is in contact with a sliding plate 34. A spring 35 is sleeved on the outer end of the connecting rod 31. The outer ends of every two connecting rods 31 are slidably connected to each other. The two ends of the spring 35 are respectively connected to the limiting plate 36 and the sliding plate 34. The inner side of the limiting plate 36 is in contact with the outer end of the furnace body 1. This structure can measure the degree of deformation of the furnace body in real time, which is convenient for timely replacement of the furnace body with a large degree of deformation, making the heat transfer of the furnace body more stable.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The furnace body 1 of the heating furnace is equipped with an inner wall cleaning assembly at its bottom and a rapid ash removal assembly at its top. The inner wall cleaning assembly includes a drive motor 41, which is fixedly installed at the bottom of the heating furnace. A rotating shaft 42 is fixedly installed at the output end of the drive motor 41. A main gear 43 is fixedly installed at one end of the rotating shaft 42. A gear ring 44 is meshed with one side of the main gear 43. A scraper 45 is fixedly installed on the top of the gear ring 44. This structure can clean the soot adhering to the inner wall of the furnace body 1. The rapid ash removal assembly includes a collection head 51, which is fixedly installed at the top of the furnace body 1. The top of the collecting head 51 is provided with a collection trough 52, and the top of the collection trough 52 is fixedly installed with an ash discharge pipe 53. The inner wall of the ash discharge pipe 53 is rotatably connected to a crushing roller 54, and one end of the ash discharge pipe 53 is fixedly installed with a connecting hose 55. The rotating shaft 42 passes through the inner wall of the heating furnace. The main gear 43 and the gear ring 44 are rotatably connected to the mounting ring 2. The scraper 45 is slidably connected to the inner wall of the heating furnace body 1. The connecting hose 55 is fixedly connected to a vacuum cleaner. The collecting head 51 passes through the top of the heating furnace body 1. This structure can clean and discharge the soot inside the heating furnace body 1, making the cleaning of the inside of the heating furnace body 1 more convenient and faster.

[0019] Working principle: When the furnace body 1 of the heating furnace is deformed, it will squeeze the limiting plate 36, which in turn squeezes the spring 35. The spring 35 drives the sliding plate 34 to adjust. The sliding plate 34 presses the pressure sensor 33. Based on the pressure on the pressure sensor 33, the degree of deformation of the furnace body 1 of the heating furnace can be measured and replaced in time. If it is necessary to clean the inside of the furnace body 1 of the heating furnace, start the drive motor 41. The drive motor 41 drives the rotating shaft 42 to rotate, the rotating shaft 42 drives the main gear 43 to rotate, the main gear 43 drives the gear ring 44 to rotate, and the gear ring 44 drives the scraper 45 to clean the inner wall of the furnace body 1 of the heating furnace. Start the vacuum cleaner, and the vacuum cleaner sucks the soot inside the furnace body 1 of the heating furnace into the collection head 51. When the soot is transferred to the ash discharge pipe 53, the crushing roller 54 uses the gas generated by the vacuum cleaner to rotate and crush and collect the soot. Finally, the soot is discharged and collected through the ash discharge pipe 53. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
