Description

Technical Field

[0001] This utility model relates to the field of smoke and dust collection technology, specifically to an electric furnace smoke and dust collection device. Background Technology

[0002] An electric furnace is an industrial device that uses electricity to generate heat. The principle is to use the Joule heat generated when an electric current passes through a conductor, or to use the eddy current generated by electromagnetic induction to heat objects. During the heating process of an electric furnace, oil stains, impurities, etc. on the surface of metal materials will be heated and volatilized or burned to produce smoke and dust. In order to comply with environmental protection regulations and protect the health of workers, it is necessary to collect the smoke and dust generated during the operation of the electric furnace. Currently, the negative pressure environment generated by the fan is usually used in the dust collection process. However, due to the fixed specifications of the collection hood, the dust collection range is limited and cannot be adjusted according to the amount of dust. As a result, some dust will escape into the surrounding environment, reducing the dust collection effect. Therefore, we need to propose an electric furnace dust collection device. Utility Model Content

[0003] The purpose of this invention is to provide an electric furnace fume collection device. By setting multiple adjustable auxiliary fume hoods at the fume inlet of the collection hood, the collection range can be expanded when there is a lot of fume, thereby improving the collection effect of fume and preventing fume from escaping into the surrounding environment, thus improving the fume collection efficiency and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electric furnace dust collection device, comprising: The exhaust pipe and the negative pressure mechanism installed in the exhaust coil are provided. The lower end of the exhaust coil is equipped with a diversion mechanism for diverting flue gas through a flange. The negative pressure mechanism enables the flue gas to be captured by negative pressure within the diversion mechanism. The diversion mechanism is equipped with multiple sets of auxiliary smoke hoods, which are arranged at equal angles and are connected to the diversion mechanism. The smoke-smoking range is increased by using multiple sets of auxiliary smoke hoods.

[0006] Preferably, the diversion mechanism includes a connecting coil, an outer cover, and an inner cover. The outer cover is fixedly connected to the upper outer side of the connecting coil, and the inner cover is fixedly connected to the lower end of the connecting coil. Multiple sets of support plates are fixedly connected between the outer cover and the inner cover, and the multiple sets of support plates are alternately arranged with multiple sets of auxiliary smoke hoods.

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: an electric furnace fume collection device, comprising: The exhaust pipe and the negative pressure mechanism 2 installed in the exhaust coil 1. The lower end of the exhaust coil 1 is equipped with a diversion mechanism 3 for diverting flue gas through a flange. The negative pressure mechanism 2 enables the diversion mechanism 3 to capture flue gas under negative pressure. The diversion mechanism 3 is equipped with multiple sets of auxiliary smoke hoods 4, which are arranged at equal angles and are connected to the diversion mechanism 3. The smoke range is increased by using multiple sets of auxiliary smoke hoods 4.

[0016] A handle 41 is fixedly connected to one side of the auxiliary smoke hood 4. An auxiliary suction hole 42 is opened on the upper surface of the auxiliary smoke hood 4. The lower surface of the auxiliary smoke hood 4 is open and a partition 43 is fixedly connected to the lower surface of the auxiliary smoke hood 4. In this embodiment, the position of the auxiliary fume hood 4 can be easily adjusted by the handle 41, so that the auxiliary fume hood 4 can be easily pulled out of the storage slot 36 to expand the range of smoke and dust collection. The auxiliary suction hole 42 can be used to ensure the smoke and dust collection effect of the diversion mechanism 3 when the auxiliary fume hood 4 is not expanded.

[0017] The diversion mechanism 3 includes a connecting coil 31, an outer cover 33, and an inner cover 34. The outer cover 33 is fixedly connected to the upper outer side of the connecting coil 31, and the inner cover 34 is fixedly connected to the lower end of the connecting coil 31. Multiple sets of support plates 35 are fixedly connected between the outer cover 33 and the inner cover 34, and the multiple sets of support plates 35 are alternately arranged with multiple sets of auxiliary smoke hoods 4. Multiple sets of negative pressure suction holes 32 are opened on the outer side of the connecting coil 31. Furthermore, the arrangement of the outer cover 33 and the inner cover 34 allows the smoke and dust to be directly captured through the inner cover 34, and the gap between the inner cover 34 and the outer cover 33 facilitates the capture of smoke and dust at the edge of the outer cover 33, thereby expanding the capture range of smoke and dust and improving practicality. The multiple sets of support plates 35 improve the installation stability of the inner cover 34 and the outer cover 33 and increase the service life of the diversion mechanism 3.

[0018] Guide blocks 5 are fixedly connected to the lower ends of both sides of the support plate 35, and a limiting groove 51 is opened on one side of the guide block 5. Magnet blocks 44 that slide in the limiting groove 51 are fixedly connected to both sides of the auxiliary smoke hood 4 and the handle 41. It is worth noting that by setting the magnet 44 to slide within the limiting groove 51, the stability of the movement of the auxiliary smoke hood 4 can be ensured, and the magnet 44 can limit the opening and closing of the auxiliary smoke hood 4, thereby improving the stability of the opening and closing of the auxiliary smoke hood 4.

[0019] The outer cover 33 has multiple storage slots 36 at the lower outer side for the auxiliary smoke hood 4 to be inserted. Both the outer cover 33 and the inner cover 34 are flared. The shape of the outer cover 33 and the inner cover 34 increases the range of smoke and dust collection and improves practicality.

[0020] The negative pressure mechanism 2 includes a bracket 21 installed in the inner cavity of the suction coil 1. A motor 22 is installed in the middle of the bracket 21. A rotating shaft is provided at the output end of the motor 22, and a rotating seat 23 is installed at the lower end of the rotating shaft. Multiple sets of blades 24 are provided on the outer side of the rotating seat 23. In a further preferred embodiment, the rotating seat 23 on the rotating shaft (not shown in the figure) is driven to rotate by the motor 22, which in turn drives multiple sets of blades 24 to rotate, thereby forming an upward airflow in the exhaust coil 1, thus creating a negative pressure environment, which facilitates the collection of external smoke and dust through the diversion mechanism 3.

[0021] A flow channel is provided between the inner cover 34 and the outer cover 33, and the width of the flow channel is greater than the width of the auxiliary suction hole 42. Both ends of the limiting groove 51 are provided with iron plates that are magnetically attracted to the magnet block 44. In addition, the flow channel facilitates the collection of smoke and dust to be concentrated and processed in the exhaust coil 1 after passing through the negative pressure suction hole 32. The iron plates (not shown in the figure) ensure the stability of the auxiliary smoke hood 4 after the magnet block 44 is attracted.

[0022] When in use, the negative pressure mechanism 2 is first started, which drives the rotating seat 23 on the rotating shaft of the motor 22 to rotate multiple sets of blades 24, so that an upward airflow is formed in the suction coil 1, thereby creating a negative pressure environment. Under the action of negative pressure, the diversion mechanism 3 begins to capture the smoke and dust generated by the electric furnace. The inner cover 34 can directly capture the smoke and dust, while the gap between the outer cover 33 and the inner cover 34 is responsible for capturing the smoke and dust at the edge of the outer cover 33. The multiple sets of negative pressure suction holes 32 connected to the outside of the coil 31 can introduce these smoke and dust into the suction coil 1 to achieve the capture of smoke and dust. Meanwhile, when a large amount of smoke and dust is emitted, the position of the handles 41 of the multiple sets of auxiliary smoke hoods 4 on the diversion mechanism 3 is adjusted, and the auxiliary smoke hoods 4 are pulled out of the storage slots 36 to expand the collection range. When the auxiliary smoke hoods 4 move, the magnets 44 on both sides slide in the limiting slots 51 of the guide block 5, and the iron pieces in the limiting slots 51 are magnetically attracted to the magnets 44, ensuring the stability of the auxiliary smoke hoods 4 when they are unfolded, thereby expanding the collection range of smoke and dust and achieving efficient collection of electric furnace smoke and dust.
