Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a dust collector for medium-frequency furnaces. Background Technology

[0002] The pulse jet bag filter is a new type of high-efficiency pulse jet bag filter that is an improvement on the bag filter. The bag filter is a dry dust filtration device that is suitable for collecting fine, dry and non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, and the filtration effect of the fibrous fabric is used to filter the dust-laden gas.

[0003] According to a public notice (Announcement No.: CN210251589U) of a pulse bag dust collector for medium frequency furnace smelting, the filter plate in the above application has a groove in the middle position, a filter screen is slidably connected in the groove, and symmetrical sliders are fixedly connected to both ends of the filter screen. The surface of the sliders is slidably connected with grooves. The up and down sliding of the filter screen has the effect of generating vibration, so that the filter screen has the function of preventing clogging.

[0004] However, in actual use, the filter screen is subjected to vertical impact forces as it slides up and down. Combined with the impact force of the airflow entering the equipment, this damages the filter screen, making it unable to effectively filter impurities. In view of this, we propose a dust collector for medium frequency furnaces. Utility Model Content

[0005] The purpose of this invention is to provide a dust collector for medium-frequency furnaces to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust collector for a medium-frequency furnace, comprising a shell, a discharge port at the bottom of the shell, an air inlet on the outer surface of the shell, an exhaust fan fixedly connected to the upper surface of the shell, an air outlet on the upper surface of the exhaust fan, and a filter assembly on the upper surface of the shell, the filter assembly comprising:

[0007] The motor is fixedly connected to the upper surface of the housing. A fixing component is fixedly connected to the output end of the motor. A filter element is fixedly connected to the outer surface of the fixing component. A movable groove is formed on the upper surface of the filter element.

[0008] The movable component is fixedly connected to the top of the inner wall of the housing; a filter plate is fixedly connected to the outer surface of the filter element; and a protrusion is fixedly connected to the outer surface of the filter plate.

[0009] A lever is hinged to the inner wall of the housing, and a small spring is fixedly connected to the side of the lever.

[0010] Preferably, the end of the small spring is fixedly connected to the inner wall of the housing, and the size of the small spring is adapted to the size of the lever, which allows the elastic force of the small spring to reset the lever.

[0011] Preferably, the dial is inclined and its position is adapted to the size of the protrusion, which allows the dial to better contact the outer surface of the protrusion.

[0012] Preferably, the position of the movable component corresponds to the position of the movable groove, and the movable component is disposed inside the movable groove, which makes the filter element more stable when rotating.

[0013] Preferably, the inner wall of the housing is provided with a cleaning component, the cleaning component including a groove, the groove being formed in the inner wall of the housing, a large spring being fixedly connected to the bottom of the inner wall of the groove, and a cleaning element being fixedly connected to the end of the large spring.

[0014] Preferably, the cleaning component is convex and is disposed inside the groove.

[0015] Preferably, the center of the large spring corresponds to the center of the cleaning component, and the size of the large spring is adapted to the size of the groove.

[0016] Compared with the prior art, this utility model provides a dust collector for medium-frequency furnaces, which has the following beneficial effects:

[0017] 1. This dust collector for medium-frequency furnaces, in order to enable the filter element to better filter impurities, gas enters the housing through the air inlet. At the same time, the motor starts, causing the fixed part to drive the filter element to rotate slowly. This allows the filter element to filter impurities in the gas, and the filter plate can filter and collect impurities in the gas. When the filter element rotates, the protrusion will contact the pusher. After the pusher passes the protrusion, the elastic force of the small spring pushes the pusher to reset and contact the next protrusion. This causes the filter element to vibrate, which in turn causes the impurities on the outer surface of the filter element to fall downward and be discharged from the discharge port.

[0018] 2. This dust collector for medium frequency furnaces, in order to better discharge impurities from the equipment, when the filter element rotates, the elastic force of the large spring pushes the cleaning element upward, so that the upper surface of the cleaning element contacts the bottom of the filter element, thereby cleaning the bottom of the filter element. This allows the filter element to better clean impurities in the gas. Attached Figure Description

Detailed Implementation

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a dust collector for a medium-frequency furnace, including a shell 1, a discharge port 2 at the bottom of the shell 1, an air inlet 3 on the outer surface of the shell 1, an exhaust fan 4 fixedly connected to the upper surface of the shell 1, an air outlet 5 on the upper surface of the exhaust fan 4, and a filter assembly 6 on the upper surface of the shell 1. The filter assembly 6 includes a motor 601, a fixing member 602, a filter element 603, a movable groove 604, a movable member 605, a filter plate 606, a protrusion 607, a lever 608, and a small spring 609.

[0026] In this embodiment of the present invention, a motor 601 is fixedly connected to the upper surface of the housing 1. A fixing member 602 is fixedly connected to the output end of the motor 601. A filter element 603 is fixedly connected to the outer surface of the fixing member 602. A movable groove 604 is formed on the upper surface of the filter element 603. A movable member 605 is fixedly connected to the top of the inner wall of the housing 1. The position of the movable member 605 corresponds to the position of the movable groove 604. The movable member 605 is disposed inside the movable groove 604, which makes the filter element 603 more stable when rotating. The outer surface of the filter element 603 is fixedly connected to... A filter plate 606 is attached, and a protrusion 607 is fixedly connected to the outer surface of the filter plate 606. A lever 608 is hinged to the inner wall of the housing 1. The lever 608 is set at an angle, and the position of the lever 608 is adapted to the size of the protrusion 607, so that the lever 608 can better contact the outer surface of the protrusion 607. A small spring 609 is fixedly connected to the side of the lever 608, and the end of the small spring 609 is fixedly connected to the inner wall of the housing 1. The size of the small spring 609 is adapted to the size of the lever 608, so that the elastic force of the small spring 609 can reset the lever 608.

[0027] Meanwhile, a cleaning component 7 is provided on the inner wall of the housing 1. The cleaning component 7 includes a slide groove 701, which is formed on the inner wall of the housing 1. A large spring 703 is fixedly connected to the bottom of the inner wall of the slide groove 701. The center of the large spring 703 corresponds to the center of the cleaning component 702. The size of the large spring 703 is adapted to the size of the slide groove 701. A cleaning component 702 is fixedly connected to the end of the large spring 703. The cleaning component 702 is convex and is located inside the slide groove 701. When the filter element 603 rotates, the elastic force of the large spring 703 pushes the cleaning component 702 upward, which makes the upper surface of the cleaning component 702 contact the bottom of the filter element 603, thereby cleaning the bottom of the filter element 603. This allows the filter element 603 to better clean impurities in the gas.

[0028] In this invention, during use, gas enters the housing 1 through the air inlet 3. Simultaneously, the motor 601 starts, causing the fixing member 602 to drive the filter element 603 to rotate slowly. This allows the filter element 603 to filter impurities in the gas, and the filter plate 606 to filter and collect impurities in the gas. At the same time, when the filter element 603 rotates, the protrusion 607 will contact the pusher 608. After the pusher 608 passes the protrusion 607, the elastic force of the small spring 609 pushes the pusher 608 to reset and contact the next protrusion 607. This causes the filter element 603 to vibrate, thereby causing impurities on the outer surface of the filter element 603 to fall downwards and be discharged from the discharge port 2.

[0029] Furthermore, when the filter element 603 rotates, the elastic force of the large spring 703 pushes the cleaning element 702 upward, which causes the upper surface of the cleaning element 702 to contact the bottom of the filter element 603, thereby cleaning the bottom of the filter element 603. This allows the filter element 603 to better clean impurities in the gas.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
