Abstract
The invention discloses a filtering funnel capable of measuring pollution degree. The filtering funnel is provided with a conical funnel (1) with a filter screen at the funnel opening of the conical funnel (1). A cylinder body (3) is coaxially mounted at the funnel opening with the filter screen, of the conical funnel (1), and the cylinder diameter of the cylinder body (3) is matched with the calibre of the funnel opening of the conical funnel (1) in size. A layer of filter paper (2) is clamped between the cylinder body (3) and the filter screen at the funnel opening of the conical funnel (1). When in use, the cylinder body (3) is matched with the filter screen of the conical funnel (1), the height of the cylinder body (3) can be selected for matching according to the matching required by the volume of a washing soiling solution for a tested insulator, and during filtering, the layer of filter paper (2) placed between the conical funnel (1) and the cylinder body (3) is used for filtering. Not only is the structure of the filtering funnel simplified, but also the operating process is simplified. Therefore, the filter efficiency during pollution degree measurement is improved.
Description
Technical field
The invention belongs to the measurement instrument technical field, be specifically related to a kind of filter funnel of measuring filthy degree.
Background technology
In recent years, along with economic development, atmospheric environment also worsens increasingly, the insulator surface contamination of bringing thus is also day by day serious, the continuous rising of its filthy degree, brought great harm to power grid security, for ensureing power grid security, the situation of change of grasping the pollution severity of insulators degree is particularly important, and the amount that therefore filthy degree is measured is also increasing.Yet up to the present, filthy degree on-line monitoring technique is still immature, therefore can only do some simple judgements to filthy degree development trend, can't realize accurate measurement.And the conclusion that traditional filthy degree measuring method is worked it out is still the foundation that current filthy degree is measured.What the filthy degree measuring method of tradition was used is filter funnel, this funnel generally is comprised of the annulated column that is positioned at top and the conical hopper with filter screen that is positioned at below, both be connected in sintering procedure, and the funnel of this structure, when filtering, need be folded filter paper, therefore, technical merit to operating personnel is had relatively high expectations, because when operation careless slightlyly just may be made a mess of filter paper, to filthy degree measurement, brings error, in addition, also there is slow, the inefficient defect of filter velocity in the traditional filtering funnel.
Summary of the invention
The technical problem to be solved in the present invention is: for the defect of prior art, provide a kind of filter funnel of measuring filthy degree, this funnel can be accelerated the speed of filtering, and promotes the efficiency of filtering, and saves the time that filthy degree is measured.
Technical scheme of the present invention is, described a kind of filter funnel of measuring filthy degree, and referring to accompanying drawing 1, this funnel as shown in Figure 1, has the conical funnel 1 of its quarrel with filter screen.This conical funnel 1 is installed a cylindrical shell 3 with coaxial cable in the quarrel of filter screen, the barrel dliameter size of this cylindrical shell 3 and the quarrel caliber size coupling of described conical funnel 1.And also accompany one deck filter paper 2 between this cylindrical shell 3 and described conical funnel 1 quarrel filter screen.
When the of the present invention a kind of filter funnel of measuring filthy degree formed thus uses, its cylindrical shell 3 matches with the filter screen of conical funnel 1, the height of cylindrical shell 3 can clean the soiling solution volume according to tested insulator and require to carry out the matching apolegamy, as shown in Figure 1, the filter paper 2 be placed in during filtration between conical funnel 1 and cylindrical shell 3 is implemented to filter.
The invention has the beneficial effects as follows, can simplify the filter funnel structure, promote the filtration efficiency in filthy degree measurement, the flow process that simplifies the operation, reduce the survey crew technical merit, promotes and measure efficiency, reduces measuring error.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of measuring a specific embodiment of filter funnel of filthy degree of the present invention.In figure, be denoted as:
1---conical funnel,
2---filter paper,
3---cylindrical shell.
Embodiment
In embodiment illustrated in fig. 1, its quarrel adopts commercially available simple glass filter funnel, quarrel upper end bore Ф 80 ㎜, quarrel lower end bore Ф 3 ㎜ with the conical funnel 1 of filter screen.The simple glass pipe that the commercially available caliber of cylindrical shell 3 employing is Ф 50 ㎜ is tailored and is formed, with the quarrel caliber size coupling of conical funnel 1, high 80 ㎜.Filter paper 2 adopts commercially available XH1363 type single page filter paper.Described conical funnel 1, filter paper 2 and cylindrical shell 3, by technique scheme and with reference to assembling shown in accompanying drawing 1, cylindrical shell 3 coaxial cables are arranged in the quarrel of conical funnel 1 with filter screen.Filter paper 2 is sandwiched between this conical funnel 1 quarrel filter screen and cylindrical shell 3.The filter funnel of measuring filthy degree of this embodiment formed thus reaches designing requirement fully through manufacturing experimently on probation being proved to be.Not only simplify the structure of filter funnel, also simplified operating process, thereby greatly promoted the filtration efficiency in filthy degree measurement.
Claims (1)
1. the filter funnel that can measure filthy degree, it is characterized in that, it has the conical funnel (1) of its quarrel with filter screen, this conical funnel (1) is installed a cylindrical shell (3) with coaxial cable in the quarrel of filter screen, the barrel dliameter size of this cylindrical shell (3) and the quarrel caliber size coupling of described conical funnel (1), and also accompany one deck filter paper (2) between this cylindrical shell (3) and described conical funnel (1) quarrel filter screen.
