Description
The technical field is as follows:
the utility model belongs to the technical field of float glass manufacturing technology and specifically relates to a sealing door of glass melting furnace inspection hole.
Background art:
the melting of glass in float glass production is accomplished in a melting furnace. Various solid powder materials are uniformly mixed according to a certain proportion and then are sent into a melting furnace, and the mixture is melted into transparent molten liquid in the melting furnace at a high temperature of more than 1500 ℃. Then the glass is shaped, annealed, cut and packaged into a finished glass product.
In order to ensure the normal operation of melting operation, the melting furnace is internally provided with a neck water bag, a stirrer, a liquid level height measurement device, a temperature measurement device and other devices, so that the breast walls on two sides of the melting furnace are provided with observation holes which are used as observation ways for observing the condition of glass liquid in the melting furnace, most of the existing observation hole sealing doors are frequently opened, but the sealing performance is lower, the temperature in the melting furnace is seriously leaked, a relatively low-temperature environment is formed near the observation holes, the temperature difference with the temperature in the melting furnace interferes with the temperature and airflow in the melting furnace, and the temperature in the melting furnace is greatly leaked due to the air draft effect.
The utility model has the following contents:
the utility model provides a sealing door of a glass melting furnace observation hole, which aims to overcome the defects in the prior art.
The application provides the following technical scheme:
the utility model provides a sealing door of glass melting furnace inspection hole, it includes and is equipped with heat preservation wall, its characterized in that in the glass melting furnace inspection hole outside: be equipped with the sleeve that corresponds the distribution with the inspection hole on the heat preservation wall, the cover is equipped with the casing outside the sleeve, and it has the heat preservation to fill between sleeve and casing, and articulated on the casing have the sealing door that covers sleeve one end, is equipped with the lug on the sealing door, is equipped with the cantilever on the heat preservation, is equipped with on the cantilever to be connected the complex hoist with the lug.
On the basis of the technical scheme, the following further technical scheme can be adopted:
the sealing door is equipped with the mounting groove including the door body in door body one side, is equipped with the spliced eye on the cell wall of mounting groove, has inserted at the mounting groove and corresponds the cooperation cock body with the sleeve, wears to be equipped with in the spliced eye and is connected the cooperation drill rod with cock body one end.
The lifting appliance comprises a lifting plate hinged to a cantilever, a fixed pulley hinged to the end portion of the lower end of the lifting plate, a traction rope correspondingly matched with the fixed pulley, and one end of the traction rope is connected with the sealing door in a matched mode.
Utility model advantage:
the utility model discloses simple structure, convenient to use, observation hole seal advantage such as effectual.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural diagram of the middle sealing door of the present invention.
The specific implementation mode is as follows:
as shown in figures 1 and 2, the sealing door of the observation hole of the glass melting furnace comprises an observation hole 1 arranged on a wall body a of the glass melting furnace, and a heat preservation wall 2 arranged on the outer side of the wall body a. The heat preservation wall 2 is provided with a shell 4 which is coaxially distributed with the observation hole 1, a sleeve 3 which is communicated with the observation hole 1 is arranged in the shell 4, the vertical drop of the sleeve 3 is larger than the diameter of the observation hole 1, a cavity is arranged between the sleeve 3 and the shell 4, and a heat preservation layer 5 made of asbestos is arranged in the cavity.
One end of the sleeve 3 extends out of the heat preservation wall 2, and an inclined chamfered edge is arranged at the end part, so that the length of the upper part of the end extending out of the heat preservation wall 2 is smaller than the length of the lower part of the end extending out of the heat preservation wall 2. The shell 4 is also extended out of the heat preservation wall 2 by a certain distance, and the shell 4 is connected with a sealing door 6 which is correspondingly matched with the sleeve 3 through a hinged seat 4 a.
The sealing door 6 comprises a door body 6a, a circular mounting groove 6b is formed in one side of the door body 6a, and a certain included angle is formed between the axis of the mounting groove 6b and the door body 6 a. A pair of inserting holes 6h is further formed in the wall of the mounting groove 6b, and the axes of the two inserting holes 6h are parallel to the surface of the door body 6 a. A lifting lug 7 is fixedly welded on the other side of the door body 6 a. A pair of hanging rings 6f which are connected and matched with the hinge seat 4a are fixedly connected to the upper end l of the door body 6 a. The hanging ring 6f is hinged with the hinge seat 4a by means of a hinge shaft penetrating through the hanging ring 6f and the hinge seat 4 a.
The plug body 6c made of refractory bricks is arranged, one section of the plug body 6c is inserted into the mounting groove 6b, the end part of the insertion end is provided with insertion holes which are coaxially distributed with the insertion holes 6h, steel rods 6d are inserted into the insertion holes 6h and the insertion holes, two ends of each steel rod 6d are fixedly welded with the corresponding insertion hole 6h, and the plug body 6c is connected with the mounting groove 6b in this way. The lower part of the plug body 6c on the left side of the mounting groove 6b is provided with a chamfered edge 6 e.
