In the grinding process of the vertical mill, after the materials are ground, the larger granular materials are thrown out of the mill under the action of the centrifugal force of the mill and fall into the scraper bin, and finally are sent into a slag spouting chute of the vertical mill through the scraping device, and slag spouting waste materials are enabled to enter the mill again through the conveying equipment for grinding.
The original design is to add a weight valve on the slag-spouting waste chute for sealing. The defects existing in the actual production and use process are as follows: (1) The valve plate is fast in abrasion, short in service life, large in replacement and maintenance workload and high in maintenance cost; (2) The valve plate is not well attached to the materials, the action amplitude is large, and the sealing effect is not good.
Disclosure of Invention
The utility model aims to provide the air locking discharging device, which is sealed by the flexible material rubber, and the flexible material is tightly attached to the surface of the waste material of the spouting slag, so that when the waste material of the spouting slag passes through the chute, the waste material of the spouting slag is automatically attached to the surface of the waste material of the spouting slag according to the quantity of the waste material of the spouting slag, the sealing effect is good, cold air outside a mill can be prevented from flowing into the mill to interfere with a flow field inside the mill, and the energy consumption of a working procedure is reduced, thereby solving the problems of large action range, poor sealing effect and large maintenance workload in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the utility model provides a lock wind discharge apparatus, includes the casing, the inboard of casing is provided with the movable seal structure that attaches to the face of jetting slag waste material.
Preferably, the movable sealing structure comprises a rotating shaft, a connecting bolt, a connecting plate and a rubber, wherein the rotating shaft is arranged on the inner wall of the shell through a bracket, the connecting plate is welded at the bottom end of the rotating shaft, and the connecting plate is connected with the rubber through the connecting bolt.
Preferably, the rubber is rubber.
Preferably, an inspection door is arranged on the inclined plane of the shell.
Preferably, a flange is welded at the top end of the shell.
Preferably, a chute is formed in the housing.
Compared with the prior art, the utility model has the following beneficial effects:
1. the utility model simplifies the structure, sets the sealing structure as movable, installs the rubber through the connecting bolt, and is movably connected through the rotating shaft, when the waste material of the slag discharge passes through the chute, the rubber is blocked, when the rubber is worn, the inspection door is opened to directly unscrew the connecting bolt to replace the rubber, the structure is simple, the replacement is convenient, and the maintenance amount and the maintenance cost are reduced;
2. according to the utility model, the flexible material rubber is adopted, and when the waste material of the slag is passed through the chute, the rubber clings to the surface of the waste material of the slag, and as the rubber is made of flexible material, the rubber clings to the surface of the waste material of the slag, so that the action amplitude is small, the sealing effect is enhanced, and the power consumption of the working procedure is reduced.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 2-4, the air locking and discharging device comprises a shell 1, wherein a movable sealing structure attached to the surface of the waste material of the slag discharge is arranged on the inner side of the shell 1, and the surface of the waste material of the slag discharge (such as a shadow M area in fig. 4) can be tightly attached through the movable sealing structure, so that the sealing effect is enhanced, and the power consumption of a working procedure is reduced.
The movable sealing structure comprises a rotating shaft 2, a connecting bolt 3, a connecting plate 4 and a rubber 5, wherein the rotating shaft 2 is arranged on the inner wall of the shell 1 through a bracket, the bottom end of the rotating shaft 2 is welded with the connecting plate 4, the connecting plate 4 is connected with the rubber 5 through the connecting bolt 3, the rubber 5 is arranged through the connecting bolt 3, the rubber 5 can be replaced, and the rubber 5 can deflect through the rotating shaft 2.
The rubber 5 is rubber, so that the rubber 5 has flexibility and can be better clung to the surface of the waste material of the spitting slag.
The inspection door 6 has been seted up on the inclined plane of casing 1, because inspection door 6 is pressed close to rubber 5, after the rubber 5 appears wearing and tearing, can change through inspection door 6, because simple structure, it is convenient to change, lock wind discharge apparatus greatly reduced on-the-spot maintenance work load and cost.
The top of the shell 1 is welded with a flange 7, and the shell 1 is connected to a vertical mill through the flange 7.
A chute 8 is formed in the housing 1, the chute 8 being intended to pass the slag waste.
Working principle: by structural modification, the rubber 5 will be in close proximity to the surface of the waste material as it passes through the chute 8, since the rubber 5 is a flexible material. The waste of the spouting slag downwards passes through the rubber 5 and can deflect through the rotating shaft 2, and after the rubber 5 is worn, the inspection door 6 is opened to directly replace the rubber 5.
