Description
Technical Field
The utility model relates to the technical field of metallurgical processing equipment, is suitable for sealing and plugging a blanking pipe, and particularly relates to a fully-sealed rod valve.
Background
In the metallurgical lime production process, the whole production line is in a negative pressure production mode, the negative pressure of the system directly influences the quality of products, the air leakage of the preheater system is caused, the negative pressure is insufficient in the furnace, the material is formed to slide at a local high temperature, the quality of the products is greatly reduced, the kiln head of the rotary kiln is caused to produce positive pressure to cause environmental pollution, and the production and maintenance are stopped when serious.
In the actual operation of the rotary kiln preheater negative pressure blanking pipe system, a gap of 1-2 mm is reserved between the rod and the valve body hole, and in the operation process, wild wind enters the system from the hole gap, so that the system negative pressure is insufficient, the system is unsmooth, and a series of system problems such as dust emission and the like and environmental pollution problems exist.
Disclosure of Invention
The utility model aims to provide a fully-closed rod valve, which solves the problems in the prior art.
The technical scheme adopted by the utility model is as follows:
the full-closed rod valve comprises a floating plate, wherein the floating plate is of a hollow structure with one end open, and the open end of the floating plate is fixedly connected to the outer wall of a blanking pipe;
a plurality of mounting holes are formed in the side wall, far away from the blanking pipe, of the floating plate, bars are mounted on the mounting holes in a clearance fit mode, a baffle is fixedly arranged at one end, located inside the floating plate, of each bar, and the baffle is used for plugging the mounting holes.
The gap between the mounting hole and the outer wall of the bar is not more than 1mm.
The bar is made of steel bars with the diameter of 20 mm.
The center position of the baffle is provided with a through hole, and the through hole is used for fixedly mounting the bar and the baffle.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
according to the utility model, the floating plate with the bars and the baffle plates is arranged on the blanking pipe, so that the bars can be pulled out from the mounting holes in the normal production process, and the cavity chamber reserved at the inner side and the baffle plates at the front end of the bars are used for plugging, so that the full-closed state is formed, the system air leakage can be effectively reduced, and the negative pressure capability is improved. The utility model has simple structure, convenient transformation, easy control and low manufacturing cost, can be widely used for blanking pipes of negative pressure and positive pressure systems, reduces wind erosion and material scouring, and prolongs the service life of equipment.
Drawings
Fig. 1 is a schematic structural view of an embodiment of the present utility model.
Figure number and name: the blanking pipe 1, the floating plate 2, the mounting holes 3, the bars 4 and the baffle 5.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. 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.
As shown in fig. 1, the fully-closed rod valve comprises a floating plate 2, wherein the floating plate 2 is a welding piece which is formed by welding steel plates, is provided with an opening at one end and is provided with a hollow chamber, and the opening end of the floating plate 2 is welded and connected to the outer wall of a blanking pipe 1; the hollow cavity of the floating plate 2 can prevent the scouring of materials and avoid the damage of the seal;
the floating plate 2 is kept away from and has offered a plurality of mounting hole 3 on the lateral wall of unloading pipe 1, and clearance fit installs bar 4 on the mounting hole 3, and the clearance between mounting hole 3 and the bar 4 outer wall is not greater than 1mm, and bar 4 selects for use the diameter to be 20 mm's steel bar, and bar 4 is located the inside one end of floating plate 2 and is provided with baffle 5, is provided with the through-hole on baffle 5's the central point put, and bar 4 welded mounting is on baffle 5, and baffle 5 can block up mounting hole 3 for negative pressure unloading pipe system can form totally enclosed state in normal operating process, has reduced the system air leakage, has improved negative pressure capacity, helps guaranteeing product quality.
It is worth noting that the bar 4 can also be replaced by adopting a screw rod and the like, and the adjustment and fixation of the extending length of the screw rod in the mounting hole 3 can be realized by externally connecting a nut, so that the influence of misoperation of the bar 3 on the product quality can be effectively reduced.
In the installation process, the rod 4 is firstly installed in the floating plate 2 in advance, then the floating plate 2 is welded on the outer wall of the positive/negative pressure blanking pipe 1, and in order to prevent the condition of poor sealing caused by deformation, the segment welding is required to be carried out firstly and then the full welding is required to be carried out.
