By the adoption of the train tank bottom liquid level measuring instrument, a unified definition standard is provided for the concept of 'empty' of a tank lorry, the remaining amount of residual liquid in the nitric acid tank lorry is accurately measured, and work is standardized and normalized; the use effect is good at present, and good social and economic benefits are achieved.

Description

Fluid level measuring instrument at the bottom of slot train

Technical field

The invention belongs to explosive technical field, relate generally to stocking and carrying, for the measuring equipment of raffinate bottom train tank car of the liquid raw material in early stage of explosive production line.

Background technology

For many years, unload containing energy company nitric acid tank car and there is loss phenomenon, in nitric acid tank car empty wagons, raffinate surplus receives company's concern, how raffinate in nitric acid tank car is reduced to the minimum problem having become my unit and conscientiously needed to solve.For a long time, the nitric acid tank car amount of unloading is in lossing state always.Analyze the reason causing the amount of unloading to be lost, mainly in tank car, whether nitric acid residual volume unloads receipts totally.And judging its residual volume, the defining standard that neither one is clear and definite, different employees unloads, and distinguishes that tank car planted agent remains the amount of raffinate also with regard to difference.Nitric acid tank car is caused to unload heavy losses.In order to make tank car raffinate surplus have a clear and definite defining standard, designing a nitric acid raffinate measuring appliance, providing foundation for post employee defines the nitric acid tank car standard of unstowing.

Existingly disclose a kind of nitric acid tank car fluid level measuring instrument used on explosive production line, solve the measurement at the bottom of slot train, show processing and fabricating tank car fluid level measuring instrument, inserting after tank car can Measurement accuracy nitric acid raffinate surplus, employee is completed accuracy and standardization that the work of unloading has had datumization.Meanwhile, improve the essence safety of employee's operation.But also there is the problem of upper tank car inconvenient operation in this measurement filtrator, need have to be solved in operation.

Summary of the invention

The present invention mainly solves the technical matters that train tank car bottom land cannot measure, and because Explosive Industry does not have similar devices to use for reference, institute thinks that measurement problem provides effective technical basis.

Bottom train tank car, the measuring equipment of raffinate is the bottom land raffinate measuring equipment designed in conjunction with the physical dimension of train tank car cylindrical tube and the design feature of two end sockets, attribute due to train tank car is horizontal tank, according to physical dimension and the wall thickness thereof of train, calculate the arc chord angle of train inwall, sector and height, the profile of sector is exactly the radian of measuring instrument, the radian of its measuring instrument is completely consistent with the radian at the bottom of slot train, measurement radian plate carves corresponding scale, also corresponding scale is carved in the lower end of its holding rod, the numerical value of holding rod and the numerical value of radian plate completely the same, measuring instrument is put into bottom land, the remaining nitric acid liquid of train tank car, immersion part is exactly that we also do not unload clean part, according to height and the size of radian, just can accurately know and have how many nitric acid liquid scale of construction not unload totally.Manufacture nitric acid raffinate measuring appliance, be used for measuring nitric acid raffinate in tank car, make the concept of tank car " empty wagons " have a unified defining standard, achieve raffinate surplus in Measurement accuracy nitric acid tank car, facilitate employee and unload.Improve tank car to a certain extent and unload receipts amount.

Fluid level measuring instrument at the bottom of slot train, comprising: holding rod, scale radian plate, scale radian scale mark, scale fixed support;

(1) fluid level measuring instrument at the bottom of slot train is mainly placed in train by holding rod, is a kind of portable carrying implement, plays the staking-out work of liquid level at the bottom of slot train simultaneously.

(2) metering plate that the radian of scale radian plate is completely consistent with the radian at the bottom of slot train, plate is carved with a certain amount of numerical value, is used for measuring the residual volume at the bottom of slot train.

(3) scale radian scale mark is in order to embody the radian line of scale radian plate more clearly, and the scale mark specially carrying out being wound around with copper cash and design.

(4) scale fixed support considers that scale radian plate insufficient strength is large, holds yielding feature, is welded and fixed with the aluminium strip of 500*30*3.

Beneficial effect

Owing to adopting technique scheme, the residual nitric acid at the bottom of slot train can be measured accurately and effectively, can unload totally in time, for company has saved a large amount of goods and materials financial resources to clean nitric acid could not be unloaded; By processing and fabricating measuring instrument, facilitate the operation of employee, employee need not use torch bucket, climbs and also has quantity not unsnatch in the observation of the manhole place of train tank car, nitric acid smog is poisonous and harmful liquid, also comparatively large to human injury, occupational hazards is large, by processing and fabricating measuring instrument, can directly measuring instrument be put at the bottom of slot train, employee need not climb the manhole place at train tank car, reduces occupational hazards, ensures safety in production; Processing and fabricating measuring instrument, makes the concept of tank car " empty wagons " have a unified defining standard, achieves raffinate surplus in Measurement accuracy nitric acid tank car, woprk standardization is standardized.Current result of use is good, has good Social and economic benef@.

Embodiment

Because nitric acid is deep-etching liquid, its nitrogen dioxide content is higher, the nitric acid smog sent, and makes operative employee judging that can tank car unload and totally there is certain difficulty, the measuring instrument of machine-shaping, solves this problem, in process, higher to the requirement of material,

The aluminum that first selection of holding rod 1 material is considered, the advantage of aluminum is that price is cheap, and material is light and handy, and convenient operation, scale bar has been selected the aluminum pipe of ∮ 32*3, is characterized in light and handy, convenient operation.

The selection of scale radian plate 2 material is selected the aluminium strip of 400*30*4, and its advantage is that corrosion resistance is strong, and be convenient to weld with holding rod 1, processing and fabricating is simple and convenient, the feature of convenient operation.

According to the characteristic of nitric acid, scale radian scale mark 3 material selects copper wire line to be wound around, is convenient to clear measurement train tank car amount of liquid like this.

In the design of scale fixed support 4, consider that scale radian plate 2 insufficient strength is large, hold yielding feature, be welded and fixed with the aluminium strip of 400*30*4.This measuring instrument all adopts argon arc welding.
