Description

Kiln door of rotary kiln head

Technical Field

The utility model relates to a cement fires equipment technical field, concretely relates to rotary kiln hood kiln door.

Background

The rotary cement kiln is a main device of a dry and wet production line of cement clinker and consists of a cylinder, a transmission device, a catch wheel, a kiln liner, a kiln tail, a kiln head, a fuel device and the like, wherein a kiln door of the rotary cement kiln is an openable sealing door arranged at a kiln opening of the kiln head, and the sealing door can prevent high temperature in the kiln from escaping outwards in the operation process, so that normal firing in the kiln is ensured.

Traditional cellar for storing things first structure is complicated, and the installation is difficult, and has a great deal of problem in the in-service use process, because the kiln door is thick and heavy in addition, and need open whole kiln door when overhauing the rotary kiln, leads to the operation inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rotary kiln hood door to a kiln door that can overhaul the rotary kiln without opening the cellar for storing things door is provided.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a rotary kiln head kiln door, includes the cellar for storing things head, the cellar for storing things head is equipped with the cellar for storing things door, the cellar for storing things door is equipped with the access hole, the fixed annular dog that has cup jointed of access hole, the lateral wall of access hole still is equipped with the spout, the spout extends to the edge of access hole, the access hole is equipped with the sealed piece that is used for covering the dog, the bottom of sealed piece is equipped with the slider with spout sliding connection, outside sealed piece stretches out the access hole, the cellar for storing things door is located the both sides of access hole and still fixes being equipped with the threaded rod, both sides it has the stripper plate to run through between the threaded rod, stripper plate and sealed piece butt, threaded rod threaded connection has the stop nut who is used for pressing the stripper plate.

The utility model discloses a theory of operation and beneficial effect: this scheme enters into the rotary kiln through the access hole and can overhauls, compares in opening whole kiln door and overhauls, overhauls more conveniently.

Because the spout that the access hole lateral wall set up extends to its edge, aim at the spout with the slider on the sealed piece after the maintenance finishes, in pushing sealed piece into the access hole, the tip of stripper plate runs through the threaded rod of both sides again, the part butt that stripper plate and sealed piece stretch out this moment, through twisting stop nut, utilize the self-locking of screw thread between stop nut and the threaded rod, the continuous stop nut that advances soon, stop nut promotes the stripper plate and removes, the stripper plate promotes sealed piece and tightly extrudees on the dog, thereby sealed piece can play better sealed effect to the access hole.

Further, the cellar door is provided with a fire observation hole. The fire observation hole can observe the combustion condition inside the rotary kiln at any time, thereby being beneficial to adjusting firepower.

Further, the sealing block is fixedly provided with a rubber handle, and the extrusion plate is abutted to the rubber handle. Handheld rubber handle is convenient for plug the maintenance mouth into with sealed piece to produce when stripper plate extrusion rubber handle and warp, can improve the pressure to sealed piece.

Furthermore, a sealing ring is arranged on one side, close to the stop block, of the sealing block. The sealing ring can improve the sealing performance between the sealing block and the stop block and can prevent heat in the kiln from escaping outwards.

Further, the spout sets up along the axis symmetry of access hole. The sliding block on the sealing block can be conveniently slid into the sliding groove, and the sealing block can be positioned better.

Furthermore, the number of the extrusion plates is two, and the axes of the two extrusion plates are mutually vertical. This arrangement allows for a stronger compression of the seal block.

Further, the cellar door is hinged with the cellar head. The arrangement is convenient for pushing the cellar door open.

Further, the fire observation hole is provided with a peephole cover. The peep hole cover can cover the fire hole to prevent heat from escaping.

Fig. 1 is a schematic structural view of a kiln door of a rotary kiln head of the present invention;

FIG. 2 is a schematic view of the structure of the compression plate of FIG. 1;

figure 3 is a vertical cross-section of the access opening of figure 1.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a sealing block 1, an extrusion plate 2, a threaded rod 3, a limit nut 4, an access hole 5, a cellar door 6, a cellar head 7, a mounting hole 8, a stop block 9, a sliding block 10 and a sliding groove 11.

In the following statements, all the directional terms such as "left", "right", "upper", "lower", etc. are based on the directions shown in the drawings, and in practice, the corresponding structures do not affect the implementation of the schemes under the condition that the relative positions are kept unchanged by the same directional changes based on the directions.

Example (b): a kiln head and a kiln door of a rotary kiln are shown in figure 1 and comprise a kiln head 7, wherein the kiln head 7 is hinged with a kiln door 6. As shown in fig. 3 and 2, the cellar door 6 is provided with an access hole 5, the access hole 5 is fixedly sleeved with a circular ring-shaped stop dog 9, the side wall of the access hole 5 is further provided with a sliding groove 11, the sliding groove 11 extends to the edge of the access hole 5, the access hole 5 is provided with a sealing block 1 for covering the stop dog 9, and the bottom of the sealing block 1 is provided with a sliding block 10 matched with the sliding groove 11 for use.

Outside sealed piece 1 stretched out access hole 5, cellar for storing things door 6 was located access hole 5's left side and right side still fixed threaded rod 3 that is equipped with, runs through between the threaded rod 3 of both sides have stripper plate 2 (threaded rod 3 wears out through mounting hole 8 that stripper plate 2 set up promptly),

stripper plate

2 and 1 butt of sealed piece, 3 threaded connection of threaded rod have be used for pressing down the stop nut 4 of stripper plate 2.

This scheme enters into the rotary kiln through access hole 5 and can overhauls, compares in opening whole kiln door and overhauls, overhauls more conveniently.

Because the spout 11 that 5 lateral walls of access hole set up extends to its edge, after the maintenance finishes with slider 10 alignment spout 11 on the sealed piece 1, push sealed piece 1 into in access hole 5, the tip with stripper plate 2 runs through the threaded rod 3 of both sides again, the part butt that stripper plate 2 and sealed piece 1 stretched out this moment, through twisting into stop nut 4, utilize the auto-lock of screw thread between stop nut 4 and the threaded rod 3, continuous precession stop nut 4, stop nut 4 promotes stripper plate 2 and removes, stripper plate 2 promotes sealed piece 1 and tightly extrudes on dog 9, thereby sealed piece 1 can play better sealed effect to access hole 5.

Preferably, the runners 11 are arranged symmetrically along the axis of the access opening 5. The arrangement is convenient for sliding the sliding block 10 on the sealing block 1 into the sliding groove 11, and can also play a role in better positioning the sealing block 1.

Preferably, the number of the pressing plates 2 is two, and the axes of the two pressing plates 2 are perpendicular to each other. This arrangement makes it possible to provide a stronger pressing action on the sealing block 1.
