Description

Technical Field

[0001] This utility model relates to the field of purification and dust removal technology, specifically to a zinc fume collection device for galvanizing pots. Background Technology

[0002] During the galvanizing process, when steel workpieces are immersed in molten zinc in a zinc bath, a large amount of zinc fumes are generated. If left untreated, these fumes permeate the workshop, not only damaging the environment but also seriously harming the health of the operators.

[0003] In response to the above situation, a zinc fume collection device for galvanizing pots is installed outside the galvanizing pot. Traditional zinc fume collection devices for galvanizing pots use a simple umbrella-shaped cover for collection. Since the umbrella-shaped cover is a certain distance from the opening at the top of the galvanizing pot, it cannot effectively collect zinc fumes, and some zinc fumes will overflow. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a zinc fume collection device for galvanizing pans, which can effectively solve the problems of zinc fume overflow during collection.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A zinc fume collection device for a galvanizing pan includes a support frame fitted onto the bottom of the galvanizing pan, and a dust-collecting structure fitted onto the outside of the galvanizing pan at the upper end of the support frame. The dust collection structure includes a dust collection ring, which is a hollow structure placed on a support frame and its upper end is higher than the galvanized pot. The inner wall of the dust collection ring is not connected to the dust collection ring and its upper inner wall is higher than the galvanized pot. Several dust collection holes are provided around the ring. A dust collection cover, wherein the dust collection cover has two integrally formed connecting tubes on both sides, and the dust collection cover is inserted into the dust collection ring through the two connecting tubes on both sides; The outer wall of the dust collection ring is equipped with an air outlet, which is connected to a ventilation duct. The air outlet of the ventilation duct is connected to a dust and smoke treatment device.

[0006] As an improvement: the dust treatment device includes a bag filter and a centrifugal fan connected to the bag filter via a ventilation duct.

[0007] As an improvement: the dust collection cover has a hollow structure, and several dust inlet holes are provided at the lower end of the dust collection cover. The internal space of the dust collection cover is connected to the dust collection ring through a connecting pipe.

[0008] As an improvement: the lower end of the bag filter is provided with a funnel-shaped ash collection trough, and the lower end of the ash collection trough is provided with a cleaning port.

[0009] As an improvement, a sealing ring is provided at the connection point between the connecting tube and the vacuum ring.

[0010] As an improvement: a fixing ring is provided at the upper end of the support frame, and the inner wall of the fixing ring is in contact with the outer wall of the dust collection ring.

[0011] The advantages of this utility model compared with the prior art are as follows: This utility model features a dust-collecting ring surrounding the galvanizing pot and a dust-collecting cover inserted into the dust-collecting ring at the top of the galvanizing pot, which can effectively absorb most of the zinc fumes and minimize the overflow of zinc fumes.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] A zinc fume collection device for galvanizing pots, as per the instruction manual. Figure 1 , 2 As shown in Figures 1 and 4, the galvanizing pot 1 includes a support frame 2 that is fitted onto the bottom of the galvanizing pot 1, and a dust-collecting structure located at the upper end of the support frame 2 is also fitted onto the outside of the galvanizing pot 1. The dust collection structure includes a dust collection ring 3, which is a hollow structure placed on a support frame 2 with its upper end higher than the galvanizing pot 1. The inner wall of the dust collection ring 3 does not contact the galvanizing pot 1, and the air in the middle can form a heat insulation layer. The upper inner wall, which is higher than the galvanizing pot 1, is provided with several dust collection holes 4. A fixing ring 13 is provided at the upper end of the support frame 2. The inner wall of the fixing ring 13 is in contact with the outer wall of the dust collection ring 3 to prevent the dust collection ring 3 from moving horizontally. A dust collection cover 11 is provided. The dust collection cover 11 has connecting pipes 10 integrally formed on both sides. The dust collection cover 11 is inserted into the dust collection ring 3 through the connecting pipes 10 on both sides. A sealing ring 16 is provided at the insertion point of the connecting pipes 10 and the dust collection ring 3 to maintain the airtightness of the dust collection structure. The dust collection cover 11 is a hollow structure. Several dust inlet holes 12 are provided at the lower end of the dust collection cover 11. The internal space of the dust collection cover 11 is connected to the dust collection ring 3 through the connecting pipes 10.

[0020] As per the instruction manual Figure 1 , 2 As shown in Figure 3, the outer wall of the dust collection ring 3 is provided with an air outlet 5, and the air outlet 5 is connected to a ventilation duct 6. The air outlet end of the ventilation duct 6 is connected to a dust treatment device. The dust treatment device includes a bag filter 7 and a centrifugal fan 9 connected to the bag filter 7 through a ventilation duct 8. The bag filter 7 is a common dust removal device and belongs to the prior art. Its structure and principle will not be disclosed in detail here. The lower end of the bag filter 7 is provided with a funnel-shaped ash collection trough 14, and the lower end of the ash collection trough 14 is provided with a dust removal port 15.

[0021] In the specific implementation of this embodiment: When the workpiece is placed in the galvanizing pot 1, zinc fumes will be generated. The centrifugal fan 9 is started to draw the air outward, and the suction force draws the zinc fumes from the first suction hole 4 and the second suction hole 12 into the suction ring 3. The zinc fumes are drawn into the bag filter 7 through the suction ring 3 and the ventilation duct 8. After being filtered by the bag filter 7, the relatively clean gas is discharged by the centrifugal fan 9.

[0022] After use, the dust filtered by the bag filter 7 falls into the funnel-shaped dust collection trough 14, and is cleaned by the dust removal port 15 at the bottom of the dust collection trough 14 and falls into the prepared container below. After long-term use of the suction ring 3 and the suction cover 11, since the suction ring 3 is directly attached to the outside of the galvanized pot 1 and placed in the support frame 2, it can be directly removed and replaced. The suction cover 11 is inserted into the upper end of the suction ring 3 and can also be directly pulled out and replaced.

[0023] The parts not disclosed in this utility model are all prior art, and their specific structures and working principles will not be described in detail.
