Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas sealing and collection devices, specifically the inverted steel frame structure for waste gas sealing and collection devices. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life, especially from chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries. The waste gas emitted has a strong odor, seriously pollutes the environment, and affects human health. Collecting and sealing waste gas for treatment to ensure it meets emission standards is currently a necessary approach to waste gas treatment and odor control. Waste gas sealing and collection devices use a structure with a supporting structure covered by a sealing membrane to seal and collect waste gas. However, long-term use of waste gas can damage the internal supporting structure, thereby greatly reducing the service life of the device.

[0003] This problem can be solved by using an inverted membrane structure. The inverted membrane structure suspends the sealing membrane inside the supporting structure, and the exhaust gas is sealed by the sealing membrane without damaging the supporting structure. However, the existing inverted steel frame structure has poor flexibility of use, and the sealing membrane fixing structure on it is prone to damage to the sealing membrane, resulting in exhaust gas leakage. The sealing membrane fixing structure cannot be adjusted according to the tilt angle of the sealing membrane, which is not practical enough. Therefore, an inverted steel frame structure for exhaust gas sealing and collection device is proposed here. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an inverted steel frame structure for a waste gas sealing collection device, which effectively solves the problems existing in the inverted steel frame structure for waste gas sealing collection devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reverse-hanging steel frame structure for a waste gas sealing collection device, comprising a first support plate, support legs at the four corners of the lower end of the first support plate, first support frames on both sides of the upper end of the first support plate, a second support plate on the upper part of the first support frame, second support frames on both sides of the upper end of the second support plate, a third support plate on the upper part of the second support frame, adjusting screws connected to the second and third support plates by threads, the adjusting screws being arranged in a circular array on the second and third support plates, an adjusting knob at the upper end of the adjusting screw, a connecting ball at the lower end of the adjusting screw, a connecting sleeve around the connecting ball, fastening bolts on the side wall of the connecting sleeve, a connecting plate at the lower end of the connecting sleeve, a first gasket at the lower end of the connecting plate, a second gasket at the lower end of the first gasket, and a magnetic suction cup at the lower end of the second gasket.

[0006] Preferably, the upper end of the support leg is bolted to the first support plate, and the lower end of the first support frame is bolted to the first support plate, so that the support leg provides overall support for the inverted steel frame structure.

[0007] Preferably, the upper end of the first support frame is bolted to the second support plate, the lower end of the second support frame is bolted to the second support plate, and the upper end of the second support frame is bolted to the third support plate. The first support frame supports the second support plate based on the first support plate, and the second support frame supports the third support plate based on the second support plate.

[0008] Preferably, the upper end of the adjusting screw is connected to the middle of the lower end of the adjusting knob by a key, and scale lines are engraved on the outer wall of the adjusting screw, which helps to accurately adjust the height of the adjusting screw.

[0009] Preferably, the upper end of the connecting ball is welded to the lower end of the adjusting screw, the outer wall of the connecting ball is rotatably connected to the inner wall of the connecting sleeve, the fastening bolt is threaded to the side wall of the connecting sleeve, and the fastening bolt is inserted into one end of the connecting sleeve and connected to the connecting ball by a clamping method. When the fastening bolt is loosened, the connecting sleeve can rotate with the assistance of the connecting ball, so that the angle of the connecting plate and the magnetic chuck can be easily adjusted.

[0010] Preferably, the lower middle part of the connecting sleeve is welded to the upper middle part of the connecting plate, the upper end of the first pad is glued to the lower end of the connecting plate, the lower end of the first pad overlaps with the upper end of the second pad, the lower end of the second pad is glued to the magnetic chuck, and the magnetic chuck and the connecting plate are connected by magnetic attraction. The sealing membrane used by the exhaust gas sealing collection device can be magnetically fixed by the magnetic chuck in conjunction with the connecting plate. Both the first pad and the second pad are made of soft rubber material, which can prevent the magnetic chuck and the connecting plate from damaging the sealing membrane.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In the inverted steel frame structure of this exhaust gas sealing and collection device, by setting up a magnetic chuck, a connecting plate, a first pad, and a second pad, the inverted steel frame structure can magnetically fix the sealing membrane used in the exhaust gas sealing and collection device in conjunction with the magnetic chuck and the connecting plate. The first and second pads can also prevent the magnetic chuck and the connecting plate from damaging the sealing membrane. The structure of the connecting ball, connecting sleeve, and fastening bolts allows the deflection angle of the connecting plate and the magnetic chuck to be easily adjusted according to the tilt angle of the sealing membrane, which is very practical. This also further prevents the magnetic chuck and the connecting plate from damaging the sealing membrane. The adjusting screw, adjusting knob, and scale line are used in conjunction with the second and third support plates to easily adjust the height of the connecting plate and the magnetic chuck at the middle and top of the sealing membrane to meet the needs of fixing and adjusting the sealing membrane.
