Description

Technical Field

[0001] The utility model relates to the technical field of lime kilns, in particular to a sealing cap for a vertical lime kiln in a sugar factory. Background Art

[0002] A lime kiln is a large-scale equipment that burns limestone and coke to produce lime and kiln gas. The quicklime and kiln gas produced by the lime kiln are cleaning agents used in carbonic acid sugar factories. The main chemical component of kiln gas is carbon dioxide. In the sugar production process, the quality of kiln gas supplied by the lime kiln directly affects the balance of the entire process of the sugar factory. It is a fixed throat link in the beet sugar production process and plays a vital role in the production of the sugar factory. In the prior art, the vertical lime kiln of the sugar factory unloads materials from the top into the kiln, and a sealing cap is required to seal it after unloading. The sealing cap of the existing lime kiln is a flat-bottomed kiln cap. During the capping process, the bottom of the kiln cap needs to be completely in a horizontal state in order to cover it properly. This state is difficult to control very accurately, and it is easy to cover it obliquely and have gaps, which is easy to cause air leakage in the subsequent process, affecting the concentration of carbon dioxide, and then affecting the purification effect in sugar production. Therefore, it is particularly necessary to improve the lime kiln sealing cap in the prior art. Utility Model Content

[0003] Aiming at the technical problem that the sealing cap of lime kiln in the prior art is a flat-bottomed kiln cap, which easily causes air leakage during use and affects the production quality of the lime kiln, a sealing cap for a vertical lime kiln in a sugar factory is provided.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A sealing cap for a vertical lime kiln in a sugar factory, the sealing cap is used to seal a feeding port of the lime kiln; the bottom of the sealing cap is a semi-ellipsoidal structure or a hemispherical structure.

[0006] Preferably, the feed opening has a structure with a large upper opening and a small lower opening.

[0007] Preferably, a square platform is horizontally arranged on the top of the sealing cap.

[0008] Preferably, a connecting column is vertically fixed at the center of the top of the sealing cap; and the square platform is fixed on the connecting column.

[0009] Preferably, the upper portion of the sealing cap is in a cone-like structure.

[0010] Preferably, support blocks are provided on the surface of the cone-like structure at the same sides as the four sides of the square platform.

[0011] Preferably, the sealing cap is a solid structure.

[0012] Preferably, the cone-like structure of the sealing cap is provided with a channel penetrating the upper and lower sides thereof at the bottom of the support block.

[0013] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0014] (1) The utility model provides a sealing cap for a vertical lime kiln in a sugar factory. By designing the bottom of the sealing cap into a semi-ellipsoidal structure or a hemispherical structure, the sealing cap can fit with the inner wall of the discharge port when placed, and has good sealing performance, thereby solving the problem of easy air leakage caused by the inappropriate bottom structure of the sealing cap and ensuring the concentration of carbon dioxide in the kiln body.

[0015] (2) In the present invention, since the bottom of the sealing cap is changed into a semi-ellipsoid structure or a hemispherical structure, the sealing cap needs to be taken out and placed when unloading, and the semi-ellipsoid structure or the hemispherical structure easily causes the sealing cap to roll, and there is a problem of instability. If the top of the sealing cap is designed as a square body, although the problem of instability can be solved, the diameter of the sealing cap is generally about 1.5 meters. If the top is a square body without improvement, it is difficult to move the sealing cap manually. Therefore, the present invention has a connecting column fixed vertically at the center of the top of the sealing cap; and a square platform is horizontally arranged on the connecting column. When placing, the sealing cap can be directly inverted, and the upper surface of the square platform is placed on the bottom surface. The sealing cap is not easy to roll, and when moving the sealing cap, it can be fixed on the connecting column by an auxiliary tool to move the sealing cap relatively easily. Of course, the present invention can also place the sealing cap side on the bottom surface by providing support blocks on the same side of the four sides of the square platform on the surface of the cone-like structure. At this time, the square platform and the support blocks are in contact with the ground, and the stability is also high.

[0016] (3) The cone-like structure of the upper portion of the sealing cap of the present invention can reduce the volume of the sealing cap and facilitate movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a clear and complete description of the technical solution of the utility model patent in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] See also Figure 1-2 The present embodiment provides a sealing cap 2 for a vertical lime kiln in a sugar factory, wherein the sealing cap 2 is used to seal a feed opening 1 of the lime kiln; the bottom of the sealing cap 2 is a semi-ellipsoidal structure or a hemispherical structure. Furthermore, the feed opening 1 of the lime kiln can be a feed opening of a lime kiln distributor. In the present utility model, the interface of the bottom of the sealing cap 2 is semi-elliptical or semi-circular, preferably semi-elliptical.

[0024] Preferably, the discharge port 1 has a structure with a large upper opening and a small lower opening. In terms of specific design, the diameter of the middle part of the sealing cap needs to be larger than the diameter of the discharge port.

[0025] In order to better place the sealing cap 2 after it is taken out, in this embodiment, a square platform 3 is horizontally arranged on the top of the sealing cap 2. Furthermore, the length and width of the square platform 3 are both smaller than the diameter of the lower opening of the feeding port 1. It is prevented that the square platform 3 is too large to affect the normal use of the sealing cap 2.

[0026] Since the sealing cap 2 is generally large in size, in order to better move the sealing cap 2, in this embodiment, the center of the top of the sealing cap 2 is vertically fixed with a connecting column 4; the square platform 3 is fixed on the connecting column 4. When moving the sealing cap 2, the sealing cap 2 can be fixed on the connecting column 4 by an auxiliary tool.

[0027] In this embodiment, the upper portion of the sealing cap 2 is in a cone-like structure, which can reduce the volume of the sealing cap 2 .

[0028] Preferably, the surface of the cone-like structure is provided with support blocks 5 on the same sides of the four sides of the square platform 3. The support blocks 5 and the square platform 3 can form two support points, and the sealing cap 2 can be tilted and placed when placing it.

[0029] Furthermore, the sealing cap of the utility model is a solid structure with a certain weight, which can prevent the sealing cap 3 from being pushed open due to the other air pressure in the lime kiln being greater than the external air pressure.

[0030] The cone-like structure of the sealing cap is provided with passages (not shown) running through the upper and lower sides thereof at the bottom of the supporting block. Since the structure is a solid structure and has a large weight, the staff can use a rope to fix the passage and move the sealing cap, which is easy to operate.

[0031] The working process and principle of this new type:

[0032] After the feeding into the lime kiln is completed, the sealing cap 2 of the utility model is used to seal the discharge pipe. Compared with the flat-bottomed sealing cap 2, the sealing cap 2 of the utility model can tightly seal the discharge pipe without air leakage, and can ensure the concentration of carbon dioxide. When moving the sealing cap 2, the connecting column 4 can be used as a fixed point and an operating point, so that the sealing cap 2 can be moved well. When the sealing cap 2 is not in use, it can be placed on the ground with the direction table as a support point alone, and the sealing cap 2 is not easy to roll. Of course, one side of the square table 3 and the support block 5 on the corresponding side can also be used as two support points of the sealing cap 2 and placed on the ground, and the sealing cap 2 is also not easy to roll. After the sealing cap 2 is improved in the utility model, it is not only well sealed and can ensure the concentration of carbon dioxide, but also easy to use and simple to operate.

[0033] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
