Description

Technical Field

[0001] This utility model relates to the field of circulating hot air furnace technology, and in particular to a high-efficiency dust-reducing circulating hot air furnace device. Background Technology

[0002] A hot air furnace is a device that uses high-temperature gas as fuel to generate heat through complete combustion and quickly heat the air, thereby performing functions such as heating and drying. A heat exchanger is installed inside the hot air furnace to accelerate heat exchange and rapidly heat the air. At the same time, a dust removal device can be added to filter dust particles in the air as the hot air circulates. Due to the powerful functions of the circulating hot air furnace, it plays an important role in industrial production.

[0003] To address this, patent specification CN219693576U discloses a flue gas circulating hot blast stove, relating to the technical field of flue gas circulating hot blast stoves. This utility model includes a hot blast fan body, with an outlet pipe connected to the surface of the hot blast fan body. An inlet air pipe is fixedly connected to the arc surface of the hot blast fan body, and a diffuser pipe is fixedly connected to the surface of the inlet air pipe. A throat pipe is fixedly connected to the other end of the diffuser pipe, and a contraction pipe is fixedly connected to the other end of the throat pipe. A wind chamber is fixedly connected to the side of the contraction pipe away from the throat pipe. A return air pipe is connected to the arc surface of the wind chamber, and the other end of the return air pipe is fixedly connected to the arc surface of the outlet air pipe. A jet pipe is fixedly connected to the surface of the wind chamber. This utility model solves the problem in the prior art where the outlet air pipe is too long, causing it to sway and shift during long-term use, leading to loose pipe connections and affecting the normal operation of the hot blast stove. While the above-mentioned hot blast stove has a good heat circulation effect during use, some problems still exist:

[0004] When the hot air furnace is in use, the hot air flow inside the hot air blower is relatively concentrated and unevenly distributed. For example, when filtering, the filter plate has a large area, but the contact area with the high-temperature gas flow is limited, which makes the filter plate prone to localized failure. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency dust-reducing circulating hot air furnace device to solve the problem of uneven hot air flow in existing hot air blowers.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency dust-reducing circulating hot air furnace device, including a heating chamber and a combustion chamber. Air inlets and outlets are fixedly connected to both sides of the heating chamber. A combustion chamber is fixedly connected to one side of the top of the heating chamber. A traction structure is fixedly connected to one side of the interior of the heating chamber. The traction structure includes a support frame, a guide vane, a rotating frame, a connecting rod, a push-pull frame, a push-pull rod, a turntable, and a motor assembly. The support frame is fixedly connected to one side of the interior of the heating chamber. A bag filter assembly is fixedly connected to the middle position of the interior of the heating chamber. An auxiliary structure is fixedly connected to the other side of the interior of the heating chamber. A combustion furnace is enclosed inside the combustion chamber. An exhaust port extends through the top of the combustion chamber. A burner is fixedly connected to one side of the combustion chamber.

[0007] In use, the air inlet and outlet of the heating chamber near the auxiliary structure are connected to the drying chamber. The air inside the drying chamber is then recirculated into the heating chamber through the air inlet and outlet on the other side for heating. When the air enters the heating chamber, it is gradually drawn by the wind and passes through the dust collection bags inside the bag filter assembly. The dust in the flowing air is filtered by the bag filter assembly. The air continues to flow, and at this time, the burner sprays gas flames into the combustion furnace for heating. The heat flows through the heat pipes and circulates into the combustion furnace. At this time, the air flows through several heat pipes, exchanging heat with the gas, thus rapidly heating the sprayed air.

[0008] Preferably, the support frame is rotatably connected to a guide vane, both ends of which are fixedly connected to a rotating frame. The top of the rotating frame is fixedly connected to a connecting rod, one end of which is fixedly connected to a push-pull frame. The push-pull frame is slidably connected to a push-pull rod, one end of which is fixedly connected to a turntable. One end of the turntable is equipped with a motor assembly. The air is reciprocated laterally adjusted as the guide vane rotates repeatedly.

[0009] Preferably, several guide vanes are rotatably connected inside the support frame, and the several guide vanes are distributed at equal intervals inside the support frame, so that the airflow direction can be controlled by the guide vanes.

[0010] Preferably, the push-pull frame and the push-pull rod have a sliding structure, thereby reducing the wear of the push-pull frame and the push-pull rod.

[0011] Preferably, the auxiliary structure includes a mounting frame, a heat-conducting pipe, a partition plate, a guide plate, and a guide groove. The mounting frame is fixedly connected to the inside of the heating chamber. A heat-conducting pipe runs through the inside of the mounting frame. A partition plate is fixedly connected to the inner side of the mounting frame. Guide plates are fixedly connected to both sides of the partition plate. A guide groove is opened inside the guide plate. The partition plate extends the airflow time and increases the heat absorption time.

[0012] Preferably, the spacers are staggered on the inside of the mounting frame so that airflow flows along the spacers.

[0013] Preferably, several guide plates are fixedly connected to both sides of the partition plate, and the several guide plates are distributed at equal intervals on both sides of the partition plate, so that the air flow time is extended by the blocking of the partition plate and the guide plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the guide vane is rotated in a cycle by the motor assembly, thereby guiding the flow of hot air. At the same time as the air flows, the air velocity is slowed down by several partition plates and guide plates, and heat exchange is fully carried out with the heat pipe.

[0015] 1. Driven by the motor assembly, the turntable drives the push-pull rod to rotate, and under the action of the push-pull frame, the connecting rod drives several rotating frames to rotate repeatedly by 180 degrees, thereby causing several guide vanes to rotate in a cycle, and thus guiding the flow of air.

[0016] 2. Several spacers are fixed alternately inside the heat pipe to extend the air flow time inside the heating chamber. Under the traction of the guide plate, the air always blows onto the heat pipe, thus allowing the air to absorb heat more fully. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-6 This utility model provides a high-efficiency dust-reducing circulating hot air furnace device, including a heating chamber 1 and a combustion chamber 3. Air inlets and outlets 2 are fixedly connected to both sides of the heating chamber 1. The combustion chamber 3 is fixedly connected to one side of the top of the heating chamber 1. A bag filter assembly 7 is fixedly connected to the middle position inside the heating chamber 1. A combustion furnace 9 is enclosed inside the combustion chamber 3. An exhaust port 4 extends through the top of the combustion chamber 3. A burner 5 is fixedly connected to one side of the combustion chamber 3. A traction structure 6 is fixedly connected to one side of the heating chamber 1. The traction structure 6 includes a support frame 601, a guide vane 602, a rotating frame 603, a connecting rod 604, a push-pull frame 605, a push-pull rod 606, a turntable 607, and a motor assembly 608. 1. A guide vane 602 is rotatably connected inside the heating chamber 1. Both ends of the guide vane 602 are fixedly connected to a rotating frame 603. A connecting rod 604 is fixedly connected to the top of the rotating frame 603. A push-pull frame 605 is fixedly connected to one end of the connecting rod 604. A push-pull rod 606 is slidably connected inside the push-pull frame 605. A turntable 607 is fixedly connected to one end of the push-pull rod 606. A motor assembly 608 is installed at one end of the turntable 607. Several guide vanes 602 are rotatably connected inside the support frame 601. The several guide vanes 602 are evenly distributed inside the support frame 601. The push-pull frame 605 and the push-pull rod 606 have a sliding structure.

[0026] See attached document Figure 2 , Figure 3 and Figure 4When the hot air blower is in use, the hot air enters the heating chamber 1 and passes through the bag filter assembly 7 for dust filtration. However, since the bag filter assembly 7 has a large filtration area and the airflow is relatively concentrated, most of the filtration is done by the bag filter assembly 7 in a certain area. After long-term use, some areas of the bag filter assembly 7 may fail, while the remaining parts still maintain their filtration characteristics. To address this, a traction structure 6 is installed at the front end of the bag filter assembly 7. Driven by the motor assembly 608, the turntable 607 drives the push-pull rod 606 to rotate. Under the action of the push-pull frame 605, the connecting rod 604 drives several rotating frames 603 to rotate repeatedly by 180 degrees, thereby causing several guide vanes 602 to rotate cyclically. This guides the airflow and makes the airflow more fully contacted with the bag filter assembly 7.

[0027] An auxiliary structure 8 is fixedly connected to the other side of the heating chamber 1. The auxiliary structure 8 includes a mounting frame 801, a heat-conducting pipe 802, a partition plate 803, a guide plate 804, and a guide groove 805. The mounting frame 801 is fixedly connected to the inside of the heating chamber 1. The heat-conducting pipe 802 passes through the inside of the mounting frame 801. The partition plate 803 is fixedly connected to the inner side of the mounting frame 801. The guide plates 804 are fixedly connected to both sides of the partition plate 803. The guide groove 805 is opened inside the guide plate 804. The partition plates 803 are staggered on the inner side of the mounting frame 801. Several guide plates 804 are fixedly connected to both sides of the partition plate 803, and the several guide plates 804 are evenly distributed on both sides of the partition plate 803.

[0028] See attached document Figure 2 , Figure 5 and Figure 6 When the hot air blower is in use, the air undergoes heat exchange as it flows through the heat pipe 802, causing the air to heat up rapidly as it absorbs heat during the flow. To ensure that the air fully absorbs heat, several spacers 803 are fixed alternately inside the heat pipe 802, thereby extending the air's flow time inside the heating chamber 1. At the same time, the guide plates 804 on both sides of the spacers 803 ensure that the air is always blown through the heat pipe 802 during the flow, thereby accelerating its heat exchange efficiency and allowing the air to absorb heat more fully.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
