AI Technical Summary
The existing mine reduction and roasting vertical grate eyelets can easily affect the sealing effect during manual mine discharge, resulting in long maintenance time for replacement of bases and high cost of spare parts.
A block mine reduction roasting vertical furnace eye hole base is designed, including the base body, gland, concentric hole, inlay groove, sealing gasket and eye hole sleeve. Through the combination and replacement of these components, the quick sealing and maintenance of eye holes is achieved.
This design allows only the gasket or eye socket to be replaced without the need for a whole base when the sealing effect is reduced, simplifying the maintenance process, reducing costs and improving eye socket life.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mining smelting and relates to a screw eye base of a lump ore reduction roasting vertical furnace. Background Art
[0002] There are mud accumulation and foreign objects stuck in the discharge port of the vertical furnace for ore reduction roasting, which requires manual discharge. Usually, manual discharge is done by opening a scratching hole on the apron of the vertical furnace, and the scratching hole is sealed with a rubber plug. When scratching, remove the rubber plug and use a scratching hook for manual discharge. When using the scratching hook for manual discharge, the scratching hole base is rubbed by the scratching hook to produce grooves, which affects the sealing effect of the scratching hole. The replacement of the scratching hole base has the disadvantages of long maintenance time and high material spare parts cost. Utility Model Content
[0003] The purpose of the utility model is to provide a base for the eyelet of a lump ore reduction roasting vertical furnace in view of the problems existing in the prior art, so as to solve the problem that the sealing effect of the eyelet is easily affected when the ore is manually discharged from the eyelet of the ore reduction roasting vertical furnace.
[0004] To this end, the utility model adopts the following technical solutions:
[0005] A lump ore reduction roasting vertical furnace eyelet base comprises a base body, a pressure cover is arranged on the top of the base body, a concentric hole is arranged in the middle of the base body, an embedded groove is arranged at the edge of the concentric hole, and an external thread is arranged on the outer edge of the base body.
[0006] Furthermore, a sealing gasket is embedded in the embedded groove, and an eyelet sleeve is provided above the sealing gasket.
[0007] Furthermore, the inner wall of the gland is provided with an internal thread, a gland hole is provided at the center, and a gland outer edge is provided on the outside.
[0008] Furthermore, the outer edge of the gland is configured as a polygon.
[0009] The beneficial effects of the utility model are:
[0010] When the sealing effect of the eyelet of the lump ore reduction roasting vertical furnace is reduced, it is only necessary to replace the sealing gasket or the eyelet sleeve in time without replacing the eyelet base as a whole. The replacement is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.
[0017] like Figure 1-4 As shown, a lump ore reduction roasting vertical furnace eyelet base comprises a base body 1, a pressure cover 4 is provided on the top of the base body 1, a concentric hole is provided in the middle of the base body 1, an embedded groove 1a is provided at the edge of the concentric hole, and an external thread 1b is provided on the outer edge of the base body 1; a sealing gasket 2 is embedded in the embedded groove 1a, and an eyelet sleeve 3 is provided on the top of the sealing gasket 2.
[0018] The inner wall of the pressure cap 4 is provided with an internal thread 4b, a pressure cap hole 4a is provided at the center, and a pressure cap outer edge 4c is provided on the outside; the diameter of the pressure cap hole 4a is larger than the inner diameter of the eyelet sleeve 3, and smaller than the outer diameter of the eyelet sleeve 3, and plays a role in fixing and pressing the eyelet sleeve 3; specifically, the pressure cap outer edge 4c is set to be a polygon, which can have an anti-slip effect.
[0019] The use process of this utility model is as follows:
[0020] First, install the base body 1 on the apron of the ore reduction roasting vertical furnace, place the sealing gasket 2 in the embedded groove 1a, and then place the eyelet sleeve 3 in the embedded groove 1a, which is located above the sealing gasket 2, and fix the pressure cover 4 on the base body 1 by rotating the outer edge 4c of the pressure cover.
[0021] When the sealing effect is reduced, the pressure cover 4 is removed by rotating the outer edge 4c of the pressure cover, the sealing gasket 2 is replaced, and the pressure cover 4 is reinstalled to seal the eyelet; when the eyelet sleeve 3 is worn, the pressure cover 4 is removed by rotating the outer edge 4c of the pressure cover, the sealing gasket 2 is replaced, and the pressure cover 4 is reinstalled to seal the eyelet. There is no need to replace the eyelet base as a whole, and the replacement is convenient.
