Description

U-shaped pH meter sleeve disassembling tool

Technical Field

The utility model relates to the technical field of pH sleeve disassembling tools, in particular to a U-shaped pH meter sleeve disassembling tool.

Background

The limestone-gypsum wet desulfurization process is the most widely applied desulfurization technology of the domestic thermal power plant at present, in the wet desulfurization process, an absorption tower slurry PH meter is important data for controlling and monitoring, and the PH value directly influences the desulfurization efficiency. However, the PH meter has some problems in the use process, such as electrode abrasion, which is caused by high slurry flow rate flowing through the glass electrode of the PH meter, so that the electrode is directly eroded and abraded; the electrode failure is caused by that the PH meter can measure the solution of strong alkali, strong acid, organic macromolecular substances and the like for a long time, so that the electrode is deactivated, the micropores of the PH electrode glass bulb are blocked, thus the indicating value is inaccurate, even the PH meter electrode is extremely easy to scale because the PH meter electrode is in a slurry environment for a long time, the electrode cannot be accurately measured, and the scaling matters are tightly adhered to the head of the PH electrode sensitive film, so that operators cannot be solved by using a conventional flushing method. To address the above issues, to ensure accurate measurements, service personnel often need to manually clean the PH electrode from the sampling tube. Because the PH measuring electrode is arranged on a pipeline with higher pressure and higher temperature, the large nut is loosened or fastened by a spanner during disassembly and assembly, and the disassembly and assembly are very hard during each verification or overhaul.

The automatic return stop lever is horizontally arranged, can rotate downwards (namely, towards the bottom direction of the U-shaped dismounting head) under the action of force, and can automatically return after the action of force disappears. When the pH meter sleeve is disassembled, the self-return stop lever automatically returns to the horizontal position, and the self-return stop lever can not rotate upwards, so that the pH meter sleeve can be prevented from flying out due to overlarge knocking force in the disassembly process, and the safety and the reliability are improved.

Preferably, the U-shaped bottom inner diameter of the U-shaped disassembling head is larger than the outer diameter of the pH meter sleeve and smaller than twice the outer diameter of the pH meter sleeve, so that the pH meter sleeve can be smoothly clamped into the U-shaped disassembling head during disassembling, and the pH meter sleeve is not easy to slide out during disassembling.

Preferably, the length of the self-return stop rod is not greater than the distance between two sides of the inside of the U-shaped dismounting head.

Preferably, the length of the automatic return stop rod is not more than one half of the distance from the upper part to the bottom of the U-shaped dismounting head, the diameter of the pH meter sleeve is less than one half of the distance from the upper part to the bottom of the U-shaped dismounting head, and the automatic return stop rod can automatically return when the pH meter sleeve is clamped into the U-shaped dismounting head.

Preferably, the inner side of the U-shaped bottom of the U-shaped dismounting head is provided with an elastic buffer pad, so that damage of the dismounting head to the pH meter sleeve in the dismounting process can be prevented.

The utility model has the beneficial effects that:

(1) The automatic return stop lever is arranged, when the pH meter sleeve is dismounted, the automatic return stop lever automatically returns to the horizontal position, and the automatic return stop lever can not rotate upwards, so that the pH meter sleeve can be prevented from flying out due to overlarge knocking force in the dismounting process, and the safety and reliability are improved;

(2) The inside elastic buffer cushion that is provided with in U type bottom of U type dismantlement head can prevent to dismantle the head to the telescopic damage of pH meter in-process.

Detailed Description

The utility model will be described in detail below with reference to the drawings and the detailed description. The embodiments shown below do not limit the inventive content described in the claims in any way. The whole contents of the constitution shown in the following examples are not limited to the solution of the utility model described in the claims.

The utility model provides a U type pH meter sleeve extracting tool, includes U type dismantlement head 1 and sets up handle 2 in U type dismantlement head 1 bottom; the upper portion of one side of the U-shaped disassembling head 1 is provided with an automatic return stop lever 3, and the automatic return stop lever 3 is rotationally connected with the U-shaped disassembling head 1. The automatic return stop lever 3 is horizontally arranged, can rotate downwards (namely, towards the bottom direction of the U-shaped dismounting head 1) under the action of force, and can automatically return after the action of force disappears. When the pH meter sleeve is dismounted, the self-return stop lever 3 automatically returns to the horizontal position, and the self-return stop lever 3 can not rotate upwards, so that the pH meter sleeve can be prevented from flying out due to overlarge knocking force in the dismounting process, and the safety and the reliability are improved.
