Description

Technical Field

[0001] This invention relates to the fields of general mechanical technology and metallurgical equipment technology, and particularly to a docking mechanism for mobile dust collector hoods. The docking mechanism enables a sealed docking of the flange interfaces of two mobile dust collector hoods (left and right). A spring clip 6 is pressed into a spring clip 5, and under the action of elastic internal force, the left and right interfaces press against a buffer sealing gasket 11. The dust collection hoods (air collecting hoods) of the two mobile dust collector hoods are connected, enclosing the dust collection space at the flange interface. During dust collection, no "wild wind" participates in the dust collection process, reducing the air volume of the dust collector fan, improving dust collection efficiency, and saving power energy. Background Technology

[0002] Steel slag, a byproduct of converter steelmaking in steel plants, requires treatment. The hot quenching process for steel slag can achieve "zero emissions," generating significant social and economic benefits. However, the hot quenching process in steel plants produces large amounts of dust and steam, creating a harsh working environment. Over time, the steam can corrode the plant and endanger worker safety. Generally, mobile dust collectors or mobile dust collector trucks are used to remove the steam and dust. Hot quenching pools are typically rectangular with a long side, limiting the wheelbase of the mobile dust collector trucks. Therefore, two or three mobile dust collector trucks are often connected side-by-side to clean the pool. However, the dust removal efficiency at the junction of the two mobile dust collector trucks affects the overall dust removal effect of the hot quenching pool. Summary of the Invention

[0003] The purpose of this invention is to provide a docking mechanism for mobile dust collection hoods, used for connecting two mobile dust collection hoods, one on the left and one on the right. After successful docking, the dust collection hoods (air hoods) of the two mobile dust collection hoods are connected, and the two flange interfaces are pressed together with buffer sealing gaskets, simultaneously confining the dust collection space at the flange interfaces. During dust collection operations, no "wild wind" participates in the dust collection, reducing the air volume of the dust collection fan, improving dust collection efficiency, and saving power. This mobile dust collection hood docking mechanism solves the problem of connecting two mobile dust collection hoods when the wheelbase of the mobile dust collection hood cannot be made too long, meeting the need for a long dust collection range in the longitudinal direction.

[0004] The present invention includes: bracket 1, adjusting shim group 2, card seat base plate 3, bolt group 4, spring card seat 5, spring card head 6, bolt group 2 7, card head base plate 8, adjusting shim group 2 9, bracket 2 10, and buffer sealing gasket 11.

[0005] The bracket 1, adjusting shim group 2, and card base plate 3 are connected in sequence, and spring card base 5 is rigidly connected to card base plate 3; the bracket 2 10, adjusting shim group 2 9, and card head base plate 8 are connected in sequence, and spring card head 6 is rigidly connected to card head base plate 8.

[0006] The buffer sealing gasket 11 is shaped with a stop edge and a rectangular through hole in the middle. It is fitted onto the flange interface of the dust collector hood truck. The stop edge fits tightly with the flange interface of the dust collector hood truck and is pressed to the bottom. The material of the buffer sealing gasket 11 is aluminum silicate ceramic plate.

[0007] The bracket 1 is rigidly connected to the left moving dust removal hood, and the bracket 2 is rigidly connected to the right moving dust removal hood. After the two moving dust removal hoods are successfully docked, the spring seat 5 and the spring head 6 are connected together by inclined contact. At the same time, the interference internal force is generated to press the buffer sealing gasket 11 through the flange interface of the left moving dust removal hood and the flange interface of the right moving dust removal hood. The thickness of the compressed buffer sealing gasket 11 is achieved by adjusting the thickness of the adjusting shim group 1 2 and the adjusting shim group 2 9.

[0008] The bracket 1 has a threaded hole, the adjusting shim group 2 has a bolt connection rough assembly through hole, and the base plate 3 has a bolt connection rough assembly through hole, which matches the thread of the bolt group 4 and is tightened by the bolt group 4.

[0009] The bracket 10 has a threaded hole, the adjusting shim group 9 has a bolt connection rough assembly through hole, and the base plate 8 has a bolt connection rough assembly through hole, which matches the thread of the bolt group 9 and is tightened by the bolt group 9.

[0010] The adjusting shim group 2 is a combination shim, composed of shims with the same thickness, length and width in series of 0.2mm, 0.3mm, 0.5mm, 1mm and 2mm.

[0011] The adjustment shim group 2 10 is a combination shim, which is composed of shims with the same thickness, length and width in the series of 0.2mm, 0.3mm, 0.5mm, 1mm and 2mm.

[0012] The aforementioned mobile dust removal hood docking mechanism includes a support frame 1 with threaded holes, and the mating surfaces of the support frame 1 and the adjusting shim group 2 are precision machined. The adjusting shim group 2 is a combination shim composed of shims of the same thickness, length, and width in series of 0.2mm, 0.3mm, 0.5mm, 1mm, and 2mm. It has rough assembly through holes (smooth holes) for bolt connection, which match the threaded holes of the support frame 1, and the left and right connecting surfaces are precision machined. The base plate 3 has rough assembly through holes (smooth holes) for bolt connection, which match the mating surfaces of the adjusting shim group 2 and the smooth holes. The spring shim group 5 is rigidly connected to the base plate 3 and is made of spring steel with good elongation properties. The bracket 210 has threaded holes, and the mating surface with the adjusting shim group 29 is precision machined. The entire shim group 29 is a combination shim, composed of shims of the same thickness, length, and width in series of 0.2mm, 0.3mm, 0.5mm, 1mm, and 2mm. It has rough assembly through holes (plain holes) for bolt connection, which match the threaded holes of the bracket 210. The left and right connecting surfaces are precision machined. The clamping head base plate 8 has rough assembly through holes (plain holes) for bolt connection, which match the mating surface and plain holes of the adjusting shim group 29. The clamping seat base plate 3 is rigidly connected to the clamping head base plate 8, and the material is spring steel with good elongation performance. The buffer sealing gasket 11 is shaped with a stop edge and a rectangular through hole in the middle. It is fitted onto its flange interface. The stop edge fits tightly with the flange interface of the dust collector hood and presses the stop edge to the bottom. The material is aluminum silicate ceramic plate, which is resistant to high temperature and impact.

[0013] The advantages of this invention are as follows: Bracket 1 is rigidly connected to the left moving dust collector trolley, serving as a support for the adjusting shim group 2, the card holder base plate 3, the bolt group 4, and the spring card holder 5. It possesses sufficient strength and rigidity to withstand the thrust from the docking of the two moving dust collector trolleys and the tension from their separation, while maintaining a essentially unchanged state. The bolted connections are secured by bolt group 4, facilitating disassembly and allowing for easy fine-tuning of the spring card holder 5. Bracket 2 10 is rigidly connected to the right moving dust collector trolley, serving as a support for the spring card head 6, bolt group 7, card head base plate 8, and adjusting shim group 9. It possesses sufficient strength and rigidity to withstand the thrust from the docking of the two moving dust collector trolleys and the tension from their separation, while maintaining a essentially unchanged state. The bolted connections are secured by bolt group 7, facilitating disassembly and allowing for easy fine-tuning of the spring card head 6. After the two mobile dust collector hoods are successfully docked, the spring seat 5 and the spring clip 6 are connected by inclined contact. Simultaneously, an interference force is generated, pressing the buffer sealing gasket 11 through the flange interface (left interface) of the left mobile dust collector hood and the flange interface (right interface) of the right mobile dust collector hood. The thickness of the compressed buffer sealing gasket 11 is adjusted using the thickness adjustment functions of shim group one 2 and shim group two 9. Fine-tuning the positions of the spring seat 5 and the spring clip 6 allows the spring clip 6 to better press into the spring seat 5 and to better pull out of the spring seat 5, as well as improving the magnitude of the pressing and pulling forces.

[0016] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] The present invention includes a bracket 1, an adjusting shim group 2, a card seat base plate 3, a bolt group 4, a spring card seat 5, a spring card head 6, a bolt group 2, a card head base plate 8, an adjusting shim group 2, a bracket 2, and a buffer sealing gasket 11.

[0018] See Figure 1 , Figure 2 , Figure 3 , Figure 5 The aforementioned mobile dust collector docking mechanism is used for docking two mobile dust collector carts, one on the left and one on the right. The two carts are of similar basic dimensions. During manufacturing, the flanged interface on the right side of the left mobile dust collector cart is called the left interface, and the flanged interface on the left side of the right mobile dust collector cart is called the right interface. A bracket 1, adjusting shim group 2, base plate 3, bolt group 4, and spring clip 5 are installed on the left mobile dust collector cart. The bracket 1 is rigidly connected to the left mobile dust collector cart. The buffer sealing gasket 11 has a rectangular through hole in the center and a stop edge. It is fitted onto the flange interface, with the stop edge tightly fitting the flange interface of the dust collector cart and pressing the stop edge to the bottom. A spring clip 6, bolt group 2, and clip 6 are also included. The base plate 8, adjusting shim group 2 9, and bracket group 2 10 are installed on the right-hand moving dust collector hood. Bracket group 2 10 is rigidly connected to the right-hand moving dust collector hood. The two moving dust collector hoods move in opposite directions on the track and approach each other. Under the action of inertial force, the spring clip 6 presses into the spring seat 5, achieving the docking connection between the two moving dust collector hoods. The spring seat 5 and the spring clip 6 are connected by inclined contact. At this time, the dust collection hoods (air collection hoods) of the two moving dust collector hoods are connected, closing the dust collection space at the flange interface. The buffer sealing gasket 11 plays a buffering role during the docking process of the two moving dust collector hoods and a sealing role during the dust collection operation of the two moving dust collector hoods. (See also...) Figure 2 , Figure 3 The two mobile dust collector hoods start running in opposite directions on the track for pre-separation. Under the initial starting force, the spring clamp 6 pulls out of the spring clamp seat 5, realizing the separation of the two mobile dust collector hoods. The magnitude of the force required for docking and separating the two mobile dust collector hoods can be achieved by changing the elasticity of the spring clamp seat 5 and the spring clamp 6, reducing the interference distance δ0, etc. Based on the principle of "three points determine a plane" and the principles of uniform force and balance, installing three sets of the aforementioned mobile dust collector hood docking mechanism is more advantageous for the docking and separation of the two mobile dust collector hoods.

[0019] See Figure 3 , Figure 4The bracket 1, adjusting shim group 2, card seat base plate 3, bolt group 4, and spring card seat 5 are installed on the left-moving dust collector trolley. The bracket 1 is rigidly connected to the left-moving dust collector trolley, and the distance H between the sealing surface of the bracket 1 and the flange interface (left interface) of the left-moving dust collector trolley is a fixed value. The spring card head 6, bolt group 2, card head base plate 8, adjusting shim group 2, and bracket 2 10 are installed on the right-moving dust collector trolley. The bracket 2 10 is rigidly connected to the right-moving dust collector trolley; the distance H between the sealing surface of the bracket 2 10 and the flange interface (right interface) of the right-moving dust collector trolley is a fixed value. Adjusting shim group 1 (2) is a combination shim with a nominal thickness of δ1, composed of shims of the same length and width with thicknesses of 0.2mm, 0.3mm, 0.5mm, 1mm, and 2mm. Adjusting shim group 2 (9) is a combination shim with a nominal thickness of δ2, composed of shims of the same length and width with thicknesses of 0.2mm, 0.3mm, 0.5mm, 1mm, and 2mm. After the two mobile dust collector hoods are docked, the thickness of the buffer sealing gasket 11 is δ, and the distance L0 between the card seat base plate 3 and the card head base plate 8 remains basically unchanged. The method to increase the compression of the buffer sealing gasket 11 by 2mm after the two mobile dust collector hoods are docked is as follows: After the two mobile dust collector hoods are successfully docked, the thickness of the buffer sealing gasket 11 becomes δ-2. According to the principle of symmetry, the thickness of adjusting shim group 1 (2) becomes δ1-1, and the thickness of adjusting shim group 2 (9) becomes δ2-1. The purpose of adjusting the compression of the buffer sealing gasket 11 after the two mobile dust removal hoods are docked is to ensure a good seal between the flange interfaces of the two mobile dust removal hoods, so that no "wild wind" participates in dust removal under dust removal conditions, reducing the air volume of the dust removal fan, improving dust removal efficiency, and saving power energy.

[0020] See Figure 6 ,again Figure 3 The diagram shows the gap left on the sealing surface after the two mobile dust removal hoods are successfully docked using the docking mechanism. Assuming the gap is 2mm, the thickness of the buffer sealing gasket 11 in its natural state, excluding the stop, is δ+1. The stop is compacted, and the remaining dimensions are the same as... Figure 3 The dimensions are the same. The method to ensure that the thickness of the buffer sealing gasket 11 remains δ after compression and the sealing surface gap becomes 0mm is as follows: Based on the principle of symmetry, adjust the thickness of gasket group 1 2 to δ1-1.5 and adjust the thickness of gasket group 2 9 to δ2-1.5; at this time, the spring clip 6 is pressed into the spring clip seat 5, the two pieces are locked together, and connected together by inclined contact, while generating interference internal force to press the buffer sealing gasket 11 through the left moving dust collector hood flange interface and the right moving dust collector hood flange interface on the left and right sides.
