Description
Technical Field
The invention relates to the technical field of performance optimization of sintering machines, in particular to a flexible slideway sealing device for a sintering machine, which seals the upper edge of an air box of the sintering machine with a slideway at the bottom of a trolley of the sintering machine, and the sintering machine.
Background
The sealing between the bottom of the sintering machine trolley and the upper edge of the bellows is related to the air leakage rate of the sintering system, so that the sintering effect and the energy consumption of the sintering machine are affected.
Sealing mode of current sintering machine platform truck bottom and bellows upper edge:
1. a slide rail of a traveling plate is arranged in a slide rail groove at the bottom of the sintering machine trolley, a fixed slide rail is arranged on the upper edge of the bellows, and sealing is realized through the close fit between the slide rail of the traveling plate and the fixed slide rail. Grease is poured between the sliding plate and the fixed slideway to form an oil film, and the oil film has a sealing function and a lubricating function. Because the air box is high in environmental temperature and large in dust, grease is quickly lost after the grease becomes thin under the action of high temperature, in the trolley moving process, the sliding abrasion and dust are adsorbed on the sliding plate, so that the sliding plate is easy to damage and block, an air leakage gap is formed, a large amount of air leakage is caused between the sintering trolley and the air box, the quality of the sintered ore is influenced, the sintering energy consumption is increased, and the sintering efficiency is low.
2. The early part of sintering machines in China use a water-cooled rubber tube as a sealing element between the upper edge of a bellows of the sintering machine and a slideway at the bottom of the trolley, so that the bellows and the slideway at the bottom of the trolley can be well sealed, but the problem of water leakage caused by burning out the rubber tube by dropped hot sintering slag exists.
In order to solve the above problems, chinese patent document CN 208282626U describes a flexible sealing plate, which includes a sealing portion in contact with a sealing slide at the bottom of a trolley, and the sealing portion forms a seal with the sealing slide at the bottom of the trolley under the action of negative pressure in a bellows. As the negative pressure in the bellows of the sintering machine reaches 15000 Pa to 18000Pa, the bonding area of the sealing parts at the two sides reaches 1000 cm to 15000cm for the trolley with the length of 1000mm to 15000mm 2 The dynamic friction force generated by the slide ways on two sides of each trolley reaches more than 100 kg. Such a large friction force generates a large pulling force on the sealing plate made of rubber, which has a large adverse effect on the service life of the sealing plate and the deflection of the sintering pallet.

All other embodiments obtained by those skilled in the art based on the examples herein shall fall within the scope of the present invention without making any inventive effort.
As an example shown in fig. 1-4, there is provided a flexible slideway sealing apparatus 2 of a sintering machine, comprising: an upper slideway 2-1 arranged in a slideway slot arranged at the bottom of the trolley 1, and a flexible lower slideway 2-2 arranged at the upper edge of the bellows 3;

the sealing portion 2-2 has a smoothly transitionally curved shape with the end portion inclined downward, and the upper surface (in the front middle portion) of the sealing portion 2-2 can be brought into contact with the lower surface of the upper run 2-1.
Referring to fig. 2, in the flexible slide sealing device 2 of the sintering machine of this example, the transverse cross section of the flexible slide 2-2 is configured in a ring shape with an opening, the sealing portion 2-2 of the flexible slide 2-2 is made of a flexible material, and the sealing portion 2-2 is in a curve shape with a smooth transition, the end portion of which is inclined downward. When the trolley 1 runs, the upper slideway 2-1 presses the highest part (in the front middle part) of the sealing part 2-2 of the flexible lower slideway 2-2 downwards, the cambered surface of the sealing part 2-2 is contacted with the lower surface of the upper slideway 2-1 to form a seal, if the upper slideway 2-1 of the trolley is not tightly sealed with the lower slideway 2-2, other cambered surfaces of the sealing part 2-2 are sucked up by the reduction of side pressure generated by air leakage flow, and the air leakage part is blocked. The sealing of the sealing part 2-2-2 and the upper slide way 2-1 is realized by reducing the side pressure generated by the air leakage air flow, after the highest cambered surface area of the sealing part 2-2 is in contact sealing with the upper slide way 2-1, if an air leakage part exists, the cambered surface of the sealing part 2-2-2 below the air leakage part is tightly attached to the corresponding area of the upper slide way 2-1 upwards; if no air leakage part exists, other cambered surfaces of the sealing part 2-2-2 are kept in a state of being separated from the upper slideway 2-1, so that unnecessary contact between the cambered surfaces of the flexible lower slideway 2-2 and the upper slideway 2-1 can be greatly reduced, and the friction force between the upper slideway 2-1 and the flexible lower slideway 2-2 is greatly reduced while the sealing part 2-2 of the flexible lower slideway 2-2 can provide good sealing. Referring to fig. 3, with respect to the seal portion 2-2-2 of the flexible glideslope 2-2, a broken line indicates a shape after suction deformation of the air leakage flow, and a solid line indicates a shape before deformation.
The flexible slideway sealing device of the sintering machine of the example further comprises: a glide slope support 2-3, a limit support table 2-4 mounted on the glide slope support 2-3; the distance L between the limiting support table and the upper slideway is 3-20 mm. In this embodiment, l=8mm is preferably taken. The limiting support table 2-4 has the function that when the trolley 1 of the sintering machine drops down, the trolley slideway is supported by the limiting support table 2-4, and the flexible glide slideway 2-2 cannot be damaged due to the falling of the trolley 1.
In this example, a flexible glidepath 2-2 is mounted to a glidepath support 2-3.
The flexible slideway sealing device of the sintering machine further comprises a pressing plate 2-5 and a flange 2-6, wherein the flange 2-6 is welded on the upper edge of the bellows 3, the lower slideway support frame 2-3 is arranged below the fixed part 2-2-1 of the flexible lower slideway 2-2, and the pressing plate 2-5 is arranged above the fixed part 2-2-1 of the flexible lower slideway 2-2. The pressing plate 2-5, the fixing part 2-2-1, the glide slope support frame 2-3 and the flange 2-6 are fixedly connected together through bolts or screws. Referring to fig. 2, the fixed portion 2-2-2 of the flexible glidepath 2-2 is placed in the glidepath support frame 2-3 and mounted to the flange 2-6 by means of the pressure plate 2-5 and the bolts 2-7.
In this example, the sealing portion 2-2-2 of the flexible glidepath 2-2 is curved or involute or elliptical arc or other curved shape with the smooth transition end sloping downward.
In this example, the cross section of the connecting portion 2-2-3 of the flexible glidepath 2-2 is in a curve shape with a smooth transition from the middle to the concave side of the bellows 3, and an arc shape is selected in this embodiment. So that the connection portion 2-2-3 can be smoothly connected with the fixing portion 2-2-1 and the sealing portion 2-2, respectively.
In this example, the sealing portion 2-2-2 of the flexible glidepath 2-2 is made of rubber or polyurethane or other air-impermeable flexible material.
The present example also provides a sintering machine comprising the flexible slideway sealing device 2 described above; along the travelling direction of the trolley 1, the flexible glide slope 2-2 comprises a working section 4 and guide sections respectively connected to two ends of the working section, wherein the guide sections incline downwards by 1-20 degrees along the working surface of the working section 4, and the working section 4 is kept in a flat state. Referring to fig. 4, the left and right flexible glides 2-2 in the drawing are respectively the trolley 1 first enters the head-end guiding section 5, then enters the working section 4, and then enters the tail-end guiding section 6. The angles alpha and beta of the head end guide section 5 and the tail end guide section 6 which are inclined downwards along the working surface (usually horizontal surface) of the working section 4 of the flexible glide slope 2-2 are both 1-20 degrees, and it is noted that the angles of alpha and beta can be inconsistent and can be respectively adjusted between 1-20 degrees according to the use requirement.
In this example, the head end guide section 5 and the tail end guide section 6 are both at 9 ° to the working surface of the flexible glidepath 2-2, i.e. α=β=9°.
It should be noted that, in the flexible slide sealing device of the sintering machine of this example, the flexible glidepath 2-2 has no right-angle section when viewed longitudinally, and can be bent downward at will, so that the working section 4, the head end guiding section 5 and the tail end guiding section 6 can be obtained by longitudinally bending the same flexible glidepath 2-2. Providing the end guide section 6 mainly takes into account that the sintering machine sometimes needs to be backed up.
The working process of the flexible slideway sealing device in the sintering machine of the example can be as follows: the trolley 1 of the sintering machine moves forward with the upper slide 2-1, first into the head end guide section 5 of the flexible lower slide 2-2. When the upper slide rail just enters the head end guide section 5 of the flexible lower slide rail 2-2, the upper slide rail is not contacted with the sealing part 2-2-2 of the flexible lower slide rail 2-2, and gradually contacts with the sealing part 2-2-2 of the flexible lower slide rail 2-2 and slightly depresses the sealing part 2-2-2 along with the forward movement of the trolley 1. Since the cross section of the sealing portion 2-2-2 is arc-shaped, the pressing down is not limited. At the moment, under the combined action of the elastic action of the sealing part 2-2-2 of the flexible glide slope 2-2 and the pressure difference between the inside and outside of the air box, a narrow strip at the front middle part of the sealing part 2-2-2 of the flexible glide slope 2-2 is contacted with the bottom surface of the upper glide slope 2-1 to form a narrow strip friction sealA belt. If the strip friction seal is provided with individual air leaks, a rapid air flow is formed between the upper surface of the seal portion 2-2-2 and the lower surface of the upper run 2-1, which produces a side pressure decrease to the upper surface of the seal portion 2-2-2 other than the strip friction seal, because of the side pressure decrease p=c-1/2 (ρv 2 ) The method comprises the steps of carrying out a first treatment on the surface of the (P-side pressure, C-constant, ρ -gas density, V-gas flow velocity), so that the side pressure decreases as the gas flow velocity increases. The side pressure drop generated by the air leakage air flow sucks up the upper surface of the sealing part 2-2-2 of the lower roll to block the air leakage part (see the broken line part of fig. 3). The sealing realized by the side pressure reduction generated by the air leakage air flow has selectivity, and only the part of the sealing surface of the narrow strip, which is provided with the air leakage, can be stuck upwards on the upper surface of the sealing part 2-2-2 below the air leakage part; the upper surface of the sealing part 2-2 below the air-leakage-proof part is not stuck upwards, and is kept in a state of being separated from the lower surface of the upper slideway 2-1, so that the friction force between the sealing part 2-2 of the flexible lower slideway 2-2 and the upper slideway 2-1 can be greatly reduced, and the sealing effect between the flexible lower slideway 2-2 and the upper slideway 2-1 can be ensured.
The sintering machine of this example installs flexible slide sealing device 2 of this example, can guarantee that bellows 3 and platform truck 1 are well sealed, reduces the frictional force of last slide 2-1 and flexible glide slope 2-2, increases flexible glide slope 2-2's life. When the trolley 1 runs, the trolley 1 firstly enters the head end guide section 5, the upper slide rail 2-1 is gradually contacted with the cambered surface of the sealing part 2-2-2 of the flexible lower slide rail 2-2, then enters the working section 4, after passing through the working section, the upper slide rail 2-1 is gradually separated from the sealing part 2-2-2 of the flexible lower slide rail 2-2, the trolley 1 enters the tail end guide section 6, and the arrangement of the head end guide section 5 and the tail end guide section 6 can prevent the sealing part 2-2-2 from being torn when the upper slide rail 2-1 is contacted with the flexible lower slide rail 2-2.
Finally, it is to be understood that the above embodiments are merely exemplary embodiments employed for the purpose of illustrating the principles of the present invention, however, the present invention is not limited thereto. Various modifications and improvements may be made by those skilled in the art without departing from the principles and spirit of the invention, and such modifications and improvements are also considered within the scope of the invention.
