Description
Technical Field
The utility model belongs to mouth of pipe plugging device field especially relates to a mouth of pipe plugging device convenient to dismouting.
Background
At present, in power generation enterprises, the gypsum disc dehydrator is widely applied to gradually replace a vacuum belt dehydrator adopted in gypsum dehydration in the power industry. The disc dehydrator mainly comprises two types, namely a ceramic disc dehydrator and a filter cloth disc dehydrator. Due to the serious technical defects of the ceramic disc dehydrator, in recent years, a plurality of power enterprises successively transform the ceramic disc dehydrator into the filter cloth disc dehydrator. The following two situations generally occur during the reforming of a disc dehydrator: firstly, the ceramic disc dehydrator directly transforms the disc into the filter cloth disc, and because the air permeability of the filter cloth type disc is larger than that of the ceramic disc, approximately 50 percent of the disc is needed to be removed in the transformation. And secondly, the actual output of the disc filter cloth dehydration is larger than the design output, the liquid level of a slurry pool of the filter cloth disc dehydrator cannot be maintained, and the original disc is disassembled into N (according to the field condition) discs for matching the output so as to reduce the output. In both the device reconstruction processes, a large number of vacuum nozzles are left to be exposed in the air, and as the device reconstruction usually needs a process of repeated test and debugging, the vacuum nozzles left after the disk is removed cannot be permanently sealed.
The prior art has two types of modes applied to the vacuum pipe orifice plugging of the dehydrator, one mode is that a plastic plug is matched with a stainless steel pipe clamp; another way is that the rubber plug (or wooden plug) is matched with the iron wire ring buckle. Wherein, the mode that the plastics stopper cooperates the stainless steel pipe strap has following two shortcomings: 1. the plastic plug is too thin and is easily blown by the compressed air discharged by back blowing. 2. The stainless steel pipe is not firmly clamped and is easily blown off by the compressed air for back blowing and discharging. The rubber plug (or wooden plug) is matched with the iron wire ring buckle and has the following two defects: 1. the rubber plug (or wooden plug) is matched with the iron wire ring buckle, and the iron wire is easy to corrode when being fixed. If stainless steel wire is used instead, the hardness and rigidity of the stainless steel wire are not suitable. 2. The iron wire is fixed, and the installation, dismantle troublesome, and dismantle the iron wire latch closure at every turn and all need scrap and do again. Therefore, there is a need for a plugging device for a pipe orifice, which can effectively seal the pipe orifice, is convenient to disassemble and assemble, and can be recycled.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defect that current mouth of pipe closing means is not convenient for the dismouting, provide a simple structure, easy dismounting, the mouth of pipe plugging device of the dismouting of being convenient for of circulated use.
In order to achieve the purpose, the utility model relates to a pipe orifice plugging device which is convenient to disassemble and assemble, comprising a fixed frame, a pressure bolt, a base nut, a pulling claw and a rubber plug; the fixing frame is provided with at least two frame bodies along the circumferential direction of the base nut; the lower end of each frame body is provided with one pull claw; the opposite inner end surfaces of the pull claws are cambered surfaces with the circle centers coinciding with the central axis of the base nut; the pressure applying bolt is arranged at the upper end of the fixing frame and is in threaded fit with the base nut.
Further, the rubber stopper is a solid taper or round table-shaped rubber stopper body. The conical or round table-shaped rubber plug can be better pressed with the pipe orifice.
Further, the support body has two or three, follows respectively the even symmetry of base nut circumference sets up. The support body that evenly sets up makes the mount remain stable throughout to make the axis coincidence of applying pressure bolt and rubber buffer, the rubber buffer atress is balanced, and is inseparabler with the mouth of pipe cooperation.
Further, the lower extreme of support body with draw the claw welding, the upper end of support body with the side welding of base nut.
The utility model has the advantages that: the upper end and the lower end of the fixing frame are respectively provided with the base nut and the pulling claw, the pulling claw is utilized to firmly buckle the external fins of the vacuum tube, and then the pressing bolt is used for pressing the rubber plug, so that the rubber plug tightly plugs the tube opening of the vacuum tube, and the fixing frame is ensured to be stable and not to fall off. Only need unscrew the bolt of exerting pressure during the dismouting and can dismantle rubber buffer and mount, dismantle simple to operate swiftly, and circulated repetitious usage, can not damage self structure.
