Abstract
The present invention discloses a seal structure for a circular cooling machine trolley unit static sealing device, which is characterized in that the present invention comprises an inner side sealing plate and an outer side sealing plate of the unit static sealing device, two rubber sealing parts contacting with the trolley bottom plate surface are arranged at the outer sides of the lower parts of the inner side sealing plate and the outer side sealing plate, an ash baffle plate which can move up and down is hung on the inner side. The present invention has the advantages that the sealing is tight, the rubber sealing part has no wear and can not be burnt, and because of the side installation structure, the installation, the maintenance and the replacement are easy.
Description
Technical field
The invention belongs to the rotary forced-air cooler that in the metallurgical mine industry sintered balls nodulizing is carried out cooling operations, be specifically related to a kind of hermetically-sealed construction that is used for ring cold machine trolley unit static sealing device.
Background technology
Existing circular cooler trolley backbar is to adopt conical surface seal, because sealing effectiveness is poor, and the air leak rate of air curtain height, ambient dust is polluted big, the energy consumption height, the manufacturing of sealing device, installation, detection, maintenance are all very difficult.Therefore, invented novel central cooler, novel central cooler is divided into sealing the town's ripple water-stop air-duct apparatus and the static seal device of movable sealing.Static seal device is the contact unit static sealing apparatus, it is to seal as a unit seal area with every single chassis, utilize the special-shaped beam of the front and back grate plate function that supports chassis, and the lower floor plane that inside and outside side seal plate and trolley body are set between special-shaped beam is formed, central cooler has several chassis just to set up the plurality of units seal area, forms a contact unit static sealing apparatus system that is made up of a plurality of unit seal area on the whole.
During cooling operations, cold wind enters chassis from seal area inboard, unit, enters the bed of material through the trolley body grate plate again, after heat exchange, enters atmosphere from charge level.Wind is after entering chassis, because unit static sealing apparatus all defines the altitude range of a sealing at the chassis four direction, only accomplishes to make special-shaped soffit plate to contact with chassis lower floor surface plate in monolateral position of special-shaped beam and compresses.All the other of special-shaped beam on one side and three parts such as medial and lateral sealing plate all keep certain interval with chassis lower floor surface plate, therefore, all there is the sealed against leakage problem in the four direction between the special-shaped beam of layer plane and inner seal plate and outside sealing plate and front and back grate plate function under the trolley body.And in cooling procedure, powder on the chassis can scatter on lower floor's flat board of chassis from the grate plate slit every now and then, especially the cooling stage in early stage after chassis when filling with substance and charging, the material that scatters is a high temperature, still 700～800 ℃ red ore deposit, these high temperature mineral aggregates also can be by wind around flat board, directly be adjacent to caulking gum spare, rubber parts is burnt, when the rubber parts scaling loss is serious, sealing is just destroyed, leaks out and will take place.
Summary of the invention
The purpose of this invention is to provide a kind of hermetically-sealed construction that is used for ring cold machine trolley unit static sealing device, this structure can make the unit seal area guarantee that the better seal effect is arranged, and contact of red ore deposit and scaling loss rubber seal can prevent to be scattered.
The present invention seeks to be achieved through the following technical solutions:
The hermetically-sealed construction that is used for ring cold machine trolley unit static sealing device, the inner seal plate and the outside sealing plate that comprise unit static sealing apparatus, in the outside of sealing plate bottom, medial and lateral the rubber seal that seals mutually with chassis base plate face is installed, the inboard hangs with movable up and down every hawk.
Describedly be provided with gathering sill every hawk, gathering sill is enclosed within on the pin on the sealing plate of medial and lateral.
Owing in trolley unit static sealing device, adopt hermetically-sealed construction of the present invention, rubber seal aspect ratio medial and lateral sealing plate in the hermetically-sealed construction to the sealing altitude range of chassis baseplane more greatly, its base reaches downwards outside the base, sealing plate bottom, medial and lateral, when chassis and the close sealing of medial and lateral sealing plate, rubber seal can be sealed the gap and guarantee that sealing is tight, accomplishes fully not leak out.Because movable is the inboard that hangs over the medial and lateral sealing plate every hawk, and can be up and down, can fall on the chassis lower floor surface plate by deadweight during sealing, powder in the chassis and caulking gum spare are separated, guarantee that the red ore deposit that scatters can the scaling loss rubber seal.
The characteristics of apparatus of the present invention are: sealing is tight, rubber seal does not have wearing and tearing and not by scaling loss because it is the side assembling structure, therefore install and maintain and replace all very convenient.
Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the schematic diagram of novel central cooler.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is an I place partial enlarged drawing among Fig. 2.
The specific embodiment
As shown in Figure 1, the unit static sealing apparatus 1 of novel central cooler is the contact unit static sealing apparatus, it is to seal as a unit seal area with every single chassis, central cooler has several chassis just to set up the plurality of units seal area, forms a contact unit static sealing apparatus system that is made up of a plurality of unit seal area on the whole.
Structure of the present invention is seen Fig. 2 and Fig. 3, the inner seal plate 4 and the outside sealing plate 5 that comprise unit static sealing apparatus, the rubber seal 6 that seals mutually with chassis base plate face is installed in the outside of sealing plate bottom, medial and lateral, its height is greater than the sealing range H of unit static sealing apparatus, the inboard hangs with movable up and down every hawk 7, be provided with gathering sill 8 every hawk 7, gathering sill 8 is enclosed within on the pin 9 on the sealing plate.
As seen from Figure 2, cold wind enters chassis from the inboard of unit static sealing apparatus, enters the bed of material 3 through trolley body grate plate 2 again, after heat exchange, enters atmosphere from charge level.As seen from Figure 3, when chassis and sealing plate 4 close sealings, rubber seal 6 can be sealed gap 11 and guarantee that sealing is tight, accomplish fully not leak out, this falls by deadweight on the chassis lower floor surface plate after hawk 7, red ore deposit that scatters in the chassis 10 and caulking gum spare 6 are separated, prevent scaling loss rubber seal 6.
Claims (2)
1. hermetically-sealed construction that is used for ring cold machine trolley unit static sealing device, it is characterized in that comprising the inner seal plate and the outside sealing plate of unit static sealing apparatus, in the outside of sealing plate bottom, medial and lateral the rubber seal that seals mutually with chassis base plate face is installed, the inboard hangs with movable up and down every hawk.
2. according to the described hermetically-sealed construction that is used for ring cold machine trolley unit static sealing device of claim 1, it is characterized in that describedly being provided with gathering sill every hawk, gathering sill is enclosed within on the pin on the sealing plate of medial and lateral.
