Description

A kind of online desludging apparatus for glass electrode surfaces

Technical field

The utility model belongs to the detection technique field, is specifically related to the online apparatus for eliminating sludge of automatic sandblast of a kind of glass electrode surface dirt.

Background technology

In fields such as metallurgy, chemical industry, biomedicine, environmental protection, use glass electrode to detect its biochemical parameters in a large number, as acid-base value, Na ion concentration, biology enzyme or the like.The detection principle of glass electrode is that the formed electromotive force of infiltration by the ion pair electrode tip glass in the detected liquid detects.

In the continuous detecting to production process, detected liquid can accumulate gradually on the glass electrode surface and form one deck dirt.This layer dirt can hinder the infiltration of ion pair glass electrode, thereby causes electrode to detect normally again.Traditional solution is by manually electrode being disassembled and with hairbrush dirt being removed.But this method not only bothers, and can't realize the production testing of serialization.Therefore, develop a kind of the needs electrode is removed from checkout gear, can in electrode work, carry out effective scavenge unit, just become the vital task that the serialization production process detects the electrode surface dirt.

Summary of the invention

The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of automatic, online, features high scale-removing effect, the online apparatus for eliminating sludge of glass electrode simple in structure, easy to use are provided.

The utility model comprises water pump, nozzle, mixing tube, wash liquid stream siphunculus, jet pipe, non-return chamber, fine sand runner pipe, sand tank.The sidewall of the vertical penetration-detection pipeline of mixing tube, and be tightly connected with detecting pipeline, the bottom of mixing tube is communicated with the wash liquid stream siphunculus, and the wash liquid stream siphunculus is provided with water pump; The mixing tube head is shrunk to truncated cone-shaped, and columnar nozzle is fixedly installed on the truncated cone-shaped head; Nozzle is arranged on the inner chamber that detects pipeline, and corresponding with the glass electrode position; Described non-return chamber is a cylindrical shape, and two end faces are the inclined-plane, and the longitudinal section in non-return chamber is inverted trapezoidal; One end of jet pipe is communicated with mixing tube, and the other end is communicated with an end on top, non-return chamber, and the other end on top, non-return chamber is communicated with an end of fine sand runner pipe, is provided with backstop in the non-return chamber; Described fine sand runner pipe is L shaped, and the other end of fine sand runner pipe is communicated with the bottom of funnel shaped sand tank, fills fine sand in the sand tank;

Described backstop comprises baffle plate and block, and baffle plate is connected with non-return cavity wall by the bearing pin that is arranged on non-return cavity wall top, and block is circular, diameter and non-return cavity wall diameter coupling; Block is fixedly installed on non-return cavity wall bottom, and the position is corresponding with bearing pin; Baffle plate rotates around bearing pin along the fine sand flow direction, and is spacing by block, stops the fine sand adverse current.

The utility model has the advantages that: 1) this device adopts fine sand to spray the glass electrode surface, can either effectively remove the dirt of serious bonding, can not cause the damage of electrode again.2) this device adopts fluidics, and the vacuum that forms during by current process jet pipe from the jet pipe sucking-off, is sprayed onto electrode surface with cleaning fluid with fine sand, and is simple in structure, not fragile.3) baffle plate in non-return chamber can effectively block the backflow of sand, not only simply but also practical.4) can realize the continuously-running duty of glass electrode one edge work, scale removal on one side.

The specific embodiment

As shown in Figure 1, online desludging apparatus for glass electrode surfaces comprises water pump 13, nozzle 3, mixing tube 14, wash liquid stream siphunculus 12, jet pipe 11, non-return chamber 9, fine sand runner pipe 8, sand tank 7.The sidewall of the vertical penetration-detection pipeline 2 of mixing tube, and be tightly connected with detecting pipeline 2, the bottom of mixing tube 14 is communicated with wash liquid stream siphunculus 12, and wash liquid stream siphunculus 12 is provided with water pump 13; Mixing tube 14 heads are shrunk to truncated cone-shaped, and columnar nozzle 3 is fixedly installed on the truncated cone-shaped head, and the internal diameter of nozzle 3 is 5mm, highly for 20mm; Nozzle 3 is arranged on the inner chamber that detects pipeline 2, and corresponding with glass electrode 1 position, and nozzle 3 is 18mm with the vertical range of glass electrode 1 bottom; Described non-return chamber 9 is a cylindrical shape, and two end faces are the inclined-plane, and the longitudinal section in non-return chamber 9 is inverted trapezoidal; One end of jet pipe 11 is communicated with mixing tube 14, and the other end is communicated with an end on 9 tops, non-return chamber, and the other end on 9 tops, non-return chamber is communicated with an end of fine sand runner pipe 8, is provided with backstop in the non-return chamber 9; Described fine sand runner pipe 8 is L shaped, and the other end of fine sand runner pipe 8 is communicated with the bottom of funnel shaped sand tank 7, fills fine sand 6 in the sand tank 7.

Described backstop comprises baffle plate 5 and block 10, and baffle plate 5 is connected with non-return chamber 9 inwalls by the bearing pin 4 that is arranged on 9 inwall tops, non-return chamber, and block 10 is circular, diameter and non-return chamber 9 inner diameters coupling; Block 10 is fixedly installed on 9 inwalls bottom, non-return chamber, and the position is corresponding with bearing pin 4; Baffle plate 5 rotates around bearing pin along the fine sand flow direction, and is spacing by block, stops the fine sand adverse current.

When needs carried out scale removal to glass electrode, when the water pump unlatching, cleaning fluid passed through nozzle directive glass electrode surface under the pressure of water pump, the vacuum that forms during current process jet pipe, fine sand from the jet pipe sucking-off, is sprayed onto electrode surface together, plays the scale removal effect.When water pump cuts out, baffle plate can rotate counterclockwise under the pressure of water, and retaining forms airtight on block, avoids water and sand to flow backwards.

The fine sand that sprays adopts clean quartz sand, particle diameter to be controlled between 0.1mm～0.5mm.Water pump adopts general centrifugal pump, and flow 2L/min is above, lift is more than 5 meters.For example can select 14CQ-5 type centrifugal pump for use, its bore 10mm, 5 meters of lifts, flow 2L/min, power 0.12KW, rotating speed 2800r/min, voltage 380V.
