Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln equipment, and particularly relates to a new type of rotary kiln supporting plate. Background Art

[0002] A rotary kiln is a thermal processing equipment for heating bulk or slurry materials, and is widely used in industrial sectors such as non-ferrous metallurgy, ferrous metallurgy, refractories, cement, chemical industry, and papermaking. The supporting plate is an important structure for transporting high-temperature materials from the smoke chamber to the inside of the kiln tail cylinder. However, due to the relatively high temperature at the position where the supporting plate is located and the relatively long length of the supporting plate, problems such as fracture, loosening, and severe wear of the supporting plate often occur. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a new type of rotary kiln supporting plate.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A new type of rotary kiln supporting plate includes several small supporting plates with the same structure. One end of each small supporting plate is installed on the end face of the smoke chamber discharge port, and the other end extends into the inside of the kiln tail cylinder. When observed along the axis direction of the cylinder, the small supporting plates are in a fan-shaped ring shape, and all the small supporting plates are connected into a fan-shaped ring supporting plate with a central angle less than or equal to 180°. Each small supporting plate includes a vertically arranged mounting plate and a material supporting plate connected to the upper side of the back of the mounting plate. The mounting plate is used to connect the smoke chamber, its upper end is a clamping end, the lower end is a supporting end, and a row of bolt holes is arranged in the middle along its length direction. The cross-sectional shape of the material supporting plate is approximately a V shape with the opening facing downwards. One end is obliquely upward connected to the mounting plate, the other end extends horizontally and the end is vertically upturned upwards. Several reinforcing ribs are arranged on both the upper surface and the lower surface of the material supporting plate. The space enclosed by the reinforcing ribs is filled with castable, and the upper surface of the castable on the upper side of the material supporting plate is solidified to form a smooth material supporting surface.

[0006] Further, the reinforcing ribs on the upper surface of the material supporting plate include transverse ribs and vertical ribs. The vertical ribs extend along the length direction of the mounting plate, the transverse ribs extend along the width direction of the mounting plate, the transverse ribs are arranged on the rear side near the middle of the material supporting plate, and the vertical rib A connecting the front side of the transverse ribs is in a V shape, and the vertical rib B connecting the rear side of the transverse ribs is in a straight shape.

[0007] Further, the vertical rib A and the vertical rib B are arranged staggeredly. For example, there are 3 V-shaped vertical ribs A and 4 straight-shaped vertical ribs B, and the specific number is adjusted according to the size of the specification and the actual engineering situation.

[0008] Further, the reinforcing ribs on the lower surface of the material supporting plate are vertical ribs.

[0009] Further, the position where the bolt holes are opened on the front surface of the mounting plate protrudes outwards to form an annular boss.

[0010] Furthermore, a circular boss protrudes outward from the upper end of the front surface of the mounting plate. There are three circular bosses, which are respectively arranged at both ends and the middle part of the mounting plate. The outer side surfaces of the circular bosses and the circular ring bosses are located in the same vertical plane.

[0011] Advantages of the present utility model:

[0012] 1. The pallet of the present application is connected by several small pallets with the same structure, which is convenient for processing and installation. The small pallets are in a fan-shaped ring shape, which is convenient for splicing. After splicing, the upper part is built with castable to form an integral structure, and there will be no leakage of materials.

[0013] 2. Bolt holes are provided in the mounting plate of the small pallet, so that the mounting plate can be connected to the smoke chamber by bolts and snap fasteners in the card slot, with double fixation, good fixation effect, and not easy to loosen and fall off.

[0014] 3. By providing reinforcing ribs on both the upper surface and the lower surface of the material supporting plate of the small pallet, the structural strength of the entire pallet is greatly improved, and conditions are also provided for subsequent casting. After the castable is built, the wear resistance and high temperature resistance of the pallet are significantly improved.

[0015] In summary, the present application solves well the problems of fracture, looseness, and falling off of the existing pallet. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the drawings and a preferred embodiment.

[0021] Refer to Figure 1 - Figure 2 , a new type of rotary kiln pallet 10 includes five small pallets with the same structure, namely small pallet A11, small pallet B12, small pallet C13, small pallet D14, and small pallet E15. One end of the small pallet is installed on the end face 20 of the outlet of the smoke chamber through a snap fastener 21, a support plate 22, and a bolt 23, and the other end extends into the kiln tail cylinder body. When observed along the axis direction of the cylinder body, the small pallet is in a fan-shaped ring shape, and all the small pallets are connected into a fan-shaped ring pallet with a central angle less than or equal to 180°.

[0022] Refer to Figure 3 - Figure 4 , taking the small supporting plate A11 as an example, it includes a vertically arranged mounting plate 111 and a material supporting plate 112 connected to the upper side of the back surface of the mounting plate; the upper end of the mounting plate 111 is a clamping end, the lower end is a supporting end, and a row of six bolt holes 1113 are formed in the middle along its length direction; the plate surface around the bolt holes 1113 protrudes outward to form an annular boss 1111. The clamping end is provided with three clamping points, which are respectively arranged at both ends and the middle part of the mounting plate, and protrude from the front side surface of the mounting plate, and are in the shape of a circular boss. The outer side surfaces of the three circular bosses and the six annular bosses are located in the same vertical plane, that is, when installing the small supporting plate, the small supporting plate only contacts the smoke chamber through the three circular bosses and the six annular bosses, and other parts do not contact; in this way, only the contact surface can be finely processed, reducing the processing cost, and the setting of the bosses also plays the role of preventing the bolts from loosening due to the uneven end surface 20 of the smoke chamber discharge port.

[0023] The cross-sectional shape of the material supporting plate 112 is roughly in the shape of a V with the opening facing downwards. One end is obliquely upward connected to the mounting plate, and the other end extends horizontally and the end is vertically upturned upwards. The upturned part plays the role of strengthening the structural strength of the supporting plate and is also beneficial to filling the casting material. A number of reinforcing ribs are provided on both the upper surface and the lower surface of the material supporting plate; the upper surface reinforcing ribs include transverse ribs 114 and vertical ribs. The vertical ribs extend along the length direction of the mounting plate, and the transverse ribs extend along the width direction of the mounting plate. The transverse rib 114 is arranged at the middle and rear side of the material supporting plate. There are 3 vertical ribs A113 connecting the front side surface of the transverse rib, which are in a V shape; there are 4 vertical ribs B115 connecting the rear side surface of the transverse rib, which are in a straight shape. The 3 vertical ribs A113 and the 4 vertical ribs B115 are arranged in a staggered manner. The lower surface reinforcing rib 116 of the material supporting plate is a vertical rib, which is roughly in a V shape. The height of the reinforcing rib is about 2 times the thickness of the material supporting plate, which is beneficial to improving the structural strength of the supporting plate, preventing it from breaking, and is also beneficial to pouring the casting material.

[0024] Refer to Figure 2 , when installing the supporting plate, angle steel 21 is welded at the outlet end of the smoke chamber as a buckle, and a supporting plate 22 is welded below the angle steel, so that both ends of the small supporting plate are clamped into the buckle and the supporting plate, and then adjusted and moved to the appropriate position and then connected to the smoke chamber through bolts 23. After all the supporting plates are installed, casting materials are applied to both the upper and lower surfaces of the supporting plate. Such a supporting plate structure is both high-temperature resistant and wear-resistant, completely avoiding various problems such as the fracture, falling off, and serious wear of the supporting plate.

[0025] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also within the protection scope of the present invention.
