Description

Technical Field

[0001] The present application relates to the technical field of grate coolers, and in particular to a sealing device for controlling leakage of CP grate coolers. Background Art

[0002] Grate cooler is an important main equipment in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker. When in use, hot clinker is unloaded from the kiln mouth onto the grate plate. Under the push of the reciprocating grate plate, it is distributed along the entire length of the grate bed to form a material bed of a certain thickness. Cooling air is blown upward from the bottom of the material bed into the material layer to cool the hot clinker. Since the hot clinker is placed on the grate cooler, its sealing structure is very important for the grate cooler.

[0003] like Figure 2 As shown, the sealing structure of the grate cooler includes a Z-shaped sealing plate 1 and a U-shaped sealing groove 2, which are respectively mounted on the grate bed 3. However, when the grate cooler is running, wear will occur between the U-shaped sealing groove 2, the Z-shaped sealing plate 1 and the grate bed 3, resulting in a gap between the sealing structure and the grate bed 3. When the gap is too large, the material on the grate bed 3 will pass through the gap into the air chamber below the grate bed 3. Utility Model Content

[0031] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0032] Embodiment 1:

[0033] See also Figure 1 and Figure 2 A sealing device for controlling leakage of a CP grate cooler comprises a grate bed 3, and the sealing device for controlling leakage of a CP grate cooler further comprises:

[0034] The Z-shaped sealing plate 1 is connected and fixed to the grate bed 3 by means of a first bolt 4;

[0035] The U-shaped sealing groove 2 is connected and fixed to the grate bed 3 by a second bolt 5;

[0036] An L-shaped adjustment plate 6 is arranged between the U-shaped sealing groove 2 and the grate bed 3;

[0037] Among them, the L-shaped adjustment plate 6 includes a horizontal plate 7 and a vertical plate 8 that are intersectingly arranged. The lower end surface of the horizontal plate 7 is in sliding contact with the upper end surface of the Z-shaped sealing plate 1. The vertical plate 8 is provided with a hole allowing the second bolt 5 to pass through. The second bolt 5 fixes the vertical plate 8 between the U-shaped sealing groove 2 and the grate bed 3 through the hole.

[0038] Specifically, according to the gap a between the upper end face of the Z-shaped sealing plate 1 and the bottom end face of the U-shaped sealing groove 2, select a suitable thickness of the L-shaped adjustment plate 6, fit the horizontal plate 7 and the vertical plate 8 of the L-shaped adjustment plate 6 with the upper end face of the Z-shaped sealing plate 1 and the side wall of the U-shaped sealing groove 2 respectively, use the second bolt 5 to fix the vertical plate 8 between the U-shaped sealing groove 2 and the grate bed 3, and the bottom of the groove edge of the U-shaped sealing groove 2 and the grate bed 3 have a spacing b of 1 mm; use the first bolt 4 to connect and fix the bottom of the Z-shaped sealing plate 1 to the grate bed 3, thereby completing the installation of the Z-shaped sealing plate 1, the U-shaped sealing groove 2 and the L-shaped adjustment plate 6;

[0039] like Figure 1 As shown, in the conventional technology, when the grate cooler is in operation, wear will occur between the U-shaped sealing groove 2, the Z-shaped sealing plate 1 and the grate bed 3, resulting in gaps a and c between the sealing structure and the grate bed 3. When the gaps are too large, the material on the grate bed 3 will pass through the gaps and enter the air chamber below the grate bed 3; Figure 2 As shown, in this embodiment, an L-shaped adjustment plate 6 is installed in the above-mentioned gap to block the gap, thereby preventing the material from entering the wind chamber through the above-mentioned gap.

[0040] Embodiment 2:

[0041] See also Figure 1 , based on the first embodiment, further and optionally, the L-shaped adjustment plate 6 is an elastic spring plate.

[0042] Specifically, during the operation of the grate cooler, the air chamber blows air into the grate bed 3 to provide a continuous supply of cooling air for cooling the material, and the spring plate has a certain contraction or elasticity. During the air supply process, the wind pressure creates a small gap between the spring plate and the U-shaped sealing groove 2 and the Z-shaped sealing plate 1, so that the cooling air can smoothly pass into the grate bed 3, thereby achieving the purpose of ventilating and cooling the material;

[0043] Meanwhile, during the operation of the grate cooler, there is vibration between the U-shaped sealing groove 2 and the grate bed 3 , and the vibration can be absorbed by the spring plate to achieve the effect of protecting the U-shaped sealing groove 2 and the grate bed 3 .

[0044] Further and optionally, a pressing plate 9 is provided above the transverse plate 7;

[0045] The pressing plate 9 is fixedly connected to the lower end surface of the groove bottom of the U-shaped sealing groove 2 , and there is a gap between the pressing plate 9 and the transverse plate 7 .

[0046] Specifically, the length of the pressing plate 9 is selected according to the length of the U-shaped sealing groove 2, the upper end surface of the pressing plate 9 is fixedly connected to the lower end surface of the groove bottom of the U-shaped sealing groove 2, and there is a 2mm gap between the lower end surface of the pressing plate 9 and the upper end surface of the horizontal plate 7, through which the cooling air can smoothly enter the grate bed 3;

[0047] In addition, since the lower end surface of the horizontal plate 7 is in sliding contact with the upper end surface of the Z-shaped sealing plate 1, the horizontal plate 7 will warp up under the action of wind pressure, thereby generating a warped edge. In this embodiment, a pressure plate 9 is provided to press the warped edge so that the gap formed between the warped edge and the Z-shaped sealing plate 1 is not too large, thereby avoiding leakage.

[0048] Further and optionally, the L-shaped adjustment plate 6 is a stainless steel spring plate.

[0049] Specifically, stainless steel spring plates have good corrosion resistance and high temperature resistance, and are suitable for harsh environments such as humidity, acid and alkali. The fatigue life of spring plates is relatively high, while the fatigue resistance of stainless steel is relatively weak. The combination of the two has certain fatigue resistance and a relatively high service life.

[0050] Further and optionally, the surface of the L-shaped adjustment plate 6 is covered with a wear-resistant layer.

[0051] Specifically, the thickness of the wear-resistant layer is 0.1 mm. Without affecting ventilation, adding the wear-resistant layer can increase the strength of the L-shaped adjustment plate 6 and improve its service life.

[0052] Further and optionally, the specifications of the L-shaped adjustment plate 6 are: length 1100 mm, width 100 mm, thickness 4 mm.

[0053] Specifically, the specifications of the L-shaped adjustment plate 6 are selected according to the length and depth of the U-shaped sealing groove 2. In this embodiment, an L-shaped adjustment plate 6 with a length of 1100 mm, a width of 100 mm, and a thickness of 4 mm is selected to better fit the U-shaped sealing groove 2.

[0054] Further and optionally, the specification of the first bolt 4 is M16×50, and the specification of the second bolt 5 is M16×45.

[0055] Specifically, the specifications of the bolts are selected according to the size of the connecting piece. In this embodiment, the requirements can be met by selecting the first bolts 4 of M16×50 and the second bolts 5 of M16×45.

[0056] In summary, the present application installs an L-shaped adjustment plate 6 in the gap generated between the sealing structure and the grate bed 3 to block the gap, thereby preventing the material from entering the wind chamber through the gap;

[0057] The L-shaped adjustment plate 6 of the present application is an elastic spring plate, which has a certain degree of contraction or elasticity. During the air supply process, the wind pressure causes a small gap between the spring plate and the U-shaped sealing groove 2 and the Z-shaped sealing plate 1, so that the cooling air can smoothly pass into the grate bed 3, thereby achieving the purpose of ventilating and cooling the material; there is vibration between the U-shaped sealing groove 2 and the grate bed 3, and the vibration can be absorbed by the spring plate to achieve the effect of protecting the U-shaped sealing groove 2 and the grate bed 3;

[0058] The present application provides a pressing plate 9 to press the warped edge so that the gap formed between the warped edge and the Z-shaped sealing plate 1 is not too large, thereby avoiding material leakage.

[0059] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
