Description

Technical Field

[0001] This utility model relates to the field of refractory sintering material processing technology, and in particular to a mixing device for refractory sintering material processing with waste heat utilization. Background Technology

[0002] Materials whose physical and chemical properties allow them to be used in high-temperature environments are called refractory materials. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. The metallurgical industry has the largest usage, accounting for 50% to 60% of the total output.

[0003] The production of refractory materials requires multiple processes, many of which generate a large amount of high-temperature air. Directly releasing this high-temperature air into the environment will cause a significant loss of heat. In addition, this high-temperature air will also contain dust, debris, and other impurities generated during the processing and mixing process, thus causing air pollution. To solve the above problems, this utility model provides a mixing device for processing refractory sintering materials with waste heat utilization. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing a mixing device for processing refractory sintering materials with waste heat utilization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mixing apparatus for processing refractory sintering materials with waste heat utilization, comprising:

[0007] The furnace body;

[0008] A spiral tube is fixedly installed inside the furnace body of the firing furnace. Straight pipes and bent pipes are fixedly connected to both ends of the spiral tube, and both straight pipes and bent pipes are fixedly extended to the outside of the firing furnace body. The other end of the straight pipe extends to the outside of the firing furnace body and is detachably connected to a filter assembly.

[0009] A suction hood is fixedly connected to the top of the firing furnace body, and the top of the suction hood is fixedly connected to one end of the bent pipe extending outside the firing furnace body.

[0010] A dual-shaft motor is fixedly installed on the top of the furnace body. The lower output shaft of the dual-shaft motor is fixedly inserted into the furnace body and a stirring shaft is fixedly installed thereon. Multiple stirring rods are fixedly installed on the surface of the stirring shaft.

[0011] Waste heat recovery components are used to extract waste heat from the furnace body into the spiral tube.

[0012] Preferably, the waste heat recovery assembly includes a rotating shaft that rotates through the top of the suction hood. An impeller is fixedly installed at one end of the rotating shaft inside the suction hood, and a small gear is fixedly installed at the other end of the rotating shaft. A large gear is fixedly installed at the end of the upper output shaft of the dual-shaft motor, and the large gear meshes with the small gear.

[0013] Preferably, the filter assembly includes a horn-shaped filter head, which has multiple filter holes on the side away from the straight pipe. A positioning ring is movably fitted on the other end surface of the horn-shaped filter head, and an internally threaded pipe is fixedly installed on the outer surface of the positioning ring, with the internally threaded pipe threaded onto the surface of the straight pipe.

[0014] Preferably, a bearing is fixedly sleeved on the surface of the rotating shaft, and the outer ring of the bearing is fixedly installed on the top of the suction shroud.

[0015] Preferably, a turbine is installed inside the horn-shaped filter head, and the turbine is fixedly installed inside the horn-shaped filter head by multiple support rods.

[0016] Compared with existing technologies, the advantages of the mixing device for processing refractory sintering materials with waste heat utilization provided by this utility model are as follows:

[0017] 1. By controlling the rotation of the large gear through the dual-shaft motor and driving the impeller to rotate at high speed through the small gear, the exhaust gas in the furnace can be drawn into the spiral tube through the bend pipe. The heat in the exhaust gas will be transferred to the surface of the spiral tube and then transferred back to the furnace, thereby making full use of the waste heat in the furnace and reducing heat loss.

[0018] 2. When the exhaust gas is discharged through the straight pipe, the horn-shaped filter head can effectively filter particulate matter in the exhaust gas, reducing air pollution. Furthermore, when the exhaust gas passes through the turbine, the relative action of the airflow can drive the turbine to rotate synchronously with the horn-shaped filter head, thereby effectively preventing particles and impurities on the filter medium from accumulating on the filter holes, reducing the risk of clogging, and achieving a self-cleaning effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 3 A mixing device for processing refractory sintering materials with waste heat utilization, comprising:

[0025] A firing furnace body 1; a spiral tube 2, fixedly installed inside the firing furnace body 1, with a straight tube 3 and a bent tube 4 fixedly connected to both ends of the spiral tube 2, and both the straight tube 3 and the bent tube 4 fixedly extending to the outside of the firing furnace body 1. The other end of the straight tube 3 extends to the outside of the firing furnace body 1 and is detachably connected to a filter assembly. The filter assembly includes a trumpet-shaped filter head 12, with multiple filter holes 13 opened on the side of the trumpet-shaped filter head 12 away from the straight tube 3. A positioning ring 14 is movably fitted on the surface of the other end of the trumpet-shaped filter head 12, and an internally threaded tube 15 is fixedly installed on the outer surface of the positioning ring 14. The internally threaded tube 15 is threaded onto the surface of the straight tube 3, which facilitates the installation and removal of the trumpet-shaped filter head 12.

[0026] The suction hood 5 is fixedly connected to the top of the furnace body 1, and the top of the suction hood 5 is fixedly connected to one end of the bent pipe 4 that extends outside the furnace body 1.

[0027] A dual-shaft motor 9 is fixedly installed on the top of the furnace body 1. The lower output shaft of the dual-shaft motor 9 is fixedly inserted into the furnace body 1 and a stirring shaft 10 is fixedly installed thereon. Multiple stirring rods 11 are fixedly installed on the surface of the stirring shaft 10. The dual-shaft motor 9 drives the stirring shaft 10 to rotate, thereby driving the multiple stirring rods 11 to rotate synchronously, which can mix the sintering materials in the furnace body 1.

[0028] The waste heat recovery assembly is used to extract the waste heat in the furnace body 1 of the firing furnace into the spiral tube 2. The waste heat recovery assembly includes a rotating shaft that rotates through the top of the suction hood 5. A bearing 18 is fixedly sleeved on the surface of the rotating shaft, and the outer ring of the bearing 18 is fixedly installed on the top of the suction hood 5 to ensure the stability of the rotating shaft during rotation.

[0029] An impeller 6 is fixedly installed at one end of the rotating shaft inside the suction hood 5, and a small gear 7 is fixedly installed at the other end of the rotating shaft. A large gear 8 is fixedly installed at the end of the upper output shaft of the dual-shaft motor 9, and the large gear 8 meshes with the small gear 7. When the dual-shaft motor 9 starts, it can drive the impeller 6 to rotate at high speed through the meshing of the large gear 8 and the small gear 7, thereby drawing the exhaust gas in the furnace body 1 of the firing furnace into the spiral tube 2 through the bend pipe 4.

[0030] Furthermore, a turbine 17 is installed inside the horn-shaped filter head 12, and the turbine 17 is fixedly installed inside the horn-shaped filter head 12 by multiple support rods 16. When the gas is discharged from the straight pipe 3, when it passes through the turbine 17, under the relative action of the airflow, it can drive the turbine 17 to rotate synchronously with the horn-shaped filter head 12, thereby effectively preventing particles and impurities on the filter medium from accumulating on the filter holes 13, reducing the risk of clogging, and achieving a self-cleaning effect. At the same time, the rotation direction of the turbine 17 is consistent with the opposite direction of the spiral of the internal threaded pipe 15, which can prevent the horn-shaped filter head 12 from disengaging from the straight pipe 3 while rotating.

[0031] The working principle of this utility model is as follows:

[0032] When in use, when the furnace body 1 is processing the sintering material, the dual-shaft motor 9 is started to drive the large gear 8 and the stirring rod 11 to rotate synchronously, and the stirring rod 11 will mix the sintering material.

[0033] Then, the large gear 8 drives the impeller 6 to rotate at high speed through the small gear 7, drawing the exhaust gas in the furnace body 1 into the spiral tube 2 through the bent pipe 4. The heat in the exhaust gas is transferred to the surface of the spiral tube 2 and then transferred back into the furnace body 1, thereby making full use of the waste heat in the furnace body 1.

[0034] Finally, when the exhaust gas is discharged from the straight pipe 3, it can effectively filter the particulate matter in the exhaust gas under the filtering action of the funnel-shaped filter head 12.

[0035] At the same time, when the gas passes through the turbine 17, under the relative action of the airflow, the turbine 17 can drive the funnel-shaped filter head 12 to rotate synchronously, thereby effectively preventing particles and impurities on the filter medium from accumulating on the filter holes 13, reducing the risk of clogging, and achieving a self-cleaning effect.

[0036] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
