Description

A kind of asphalt storage tank liquid level read out instrument

The utility model relates to the fields of measurement of liquid level, relates to a kind of asphalt storage tank liquid level read out instrument particularly.

The pitch that highway engineering is used generally adopts the large-scale vertical basin to store, and for grasping what of pitch reserves at any time, its liquid level shows very important.The liquid level read out instrument of prior art medium pitch basin adopts traditional float level meter to show liquid level usually.Its structure is that a float is placed in the basin is a steel rope on the float, steel rope is walked around fixed pulley and is stretched out outside the jar, the other end is a weight, on 5 weights pointer is housed, when the pitch liquid level rises (decline), float rises (decline) thereupon, and jar outer weight and pointer be decline (rising) accordingly then.Though this kind structure can reflect the height of liquid level at any time, the lifting of pointer relative liquid surface, visual in image property is poor, and incongruent look read the custom, cause illusion easily.Also have ball float directly to place in the asphalt tank, because the characteristic that pitch low temperature solidifies does not usually cause liquid level to show mistake because of local pitch does not melt.Along with continuous progress in science and technology, people thirst for appearing on the market of a kind of new asphalt storage tank liquid level read out instrument, to satisfy the needs of highway engineering.

The purpose of this utility model provides a kind of pitch storage level gauge, and it can show the position of liquid level at any time, compares visual pattern again, is convenient to read.

Task of the present utility model realizes by following proposal.The principal feature of its structure is in asphalt storage tank 20, is provided with

float bowl

11, and 21 groove was 17 li at the bottom of its lower end was stretched into jar, and stretch out outside the tank deck 18 its upper end, and its periphery is provided with conduction oil interlayer pipe 10, which is provided with conduction oil into and out of pipe 16 and 5; Float bowl 11 inner chambers are inserted float 13, there is steel rope 8 in system on it, 8 fixed pulley 1,3 and the transition weights of walking around on the support of tank deck 18 7 fuse, also be that steel rope 6 is arranged on the transition weight 7, fixed pulley 2 backs that steel rope 6 is walked around tank deck 18 upper brackets fuse with weight pointer 12, and weight pointer 12 is provided with pointer.Be provided with square type pipe 15 and C shaped steel 14 on outside asphalt storage tank 20 heat-insulation layers 19, transition weight 7 and weight pointer 12 respectively within it the chamber make perpendicular movement, C shaped steel 14 is provided with graduated scale 4.

The characteristics of its structure are that float bowl 11 and outer conduction oil interlayer pipe 10 connect solid on tank skin 20 by support 9.

The utility model is because adopted on the basis of conventional display device, set up the transition weight, the structure design of steel rope, fixed pulley, so it has reasonable in design, simple in structure, can be more image show the lifting of tank level, intuitive and convenient more in the use can satisfy the needs of highway engineering.

The concrete structure of utility model is provided by following examples and accompanying drawing.

Fig. 1 is according to the structural front view that the utility model proposes a kind of asphalt storage tank liquid level read out instrument.

Fig. 2 is the A-A section-drawing of Fig. 1.

Describe details and service condition in detail below in conjunction with accompanying drawing 1, Fig. 2 according to a kind of pitch asphalt storage tank liquid level read out instrument that the utility model proposes.

This device is included in and is provided with float bowl 11 in the

asphalt storage tank

20, and 21 groove was 17 li at the bottom of its lower end was stretched into jar, guaranteed that a float bowl lowest order and jar outer C shaped steel 14 high scale line lowest orders are zero.Stretch out outside the tank deck 18 its upper end, and the float bowl periphery is provided with conduction oil interlayer pipe 10, which is provided with conduction oil into and out of pipe 16 and 5, and participate in the circulation of asphalt tank heat-conducting oil system by it, make it to absorb heat, the float indoor asphalt does not solidify when guaranteeing work, so that the free floating of float 13.Float 13, steel rope 8, fixed pulley 1,2,3, transition weight 7, it is whole that steel rope 6 and weight pointer 12 connect into a motion, and float drives 7 motions of transition weight under the effect of buoyancy and gravitational difference, and transition weight 7 drives 12 motions of weight pointer again, transition weight pointer 12 is made perpendicular movement at C shaped steel 14 inner chambers, and C shaped steel 14 is provided with scale graduation 4 and cooperates the liquid level that marks in the asphalt storage tank 20 with weight pointer 12.Fixed pulley 1,2,3 is installed on the support of tank deck 18, motion in the rectangular tube 15 of transition weight 7 outside tank skin heat-insulation layer 19.Its float bowl 10 and outer conduction oil interlayer pipe 10 connect solid on tank skin 20 by support 9, to guarantee the stability of float bowl 11.

The working process of this device is, after asphalt storage tank 20 beginning heating works, conduction oil begins circulation, full conduction oil in the interlayer pipe 10, conduction oil is by inlet pipe 16, going out pipe 5 circulates, assurance float bowl 11 is worked under the heating of high-temperature hot oil, and pitch does not solidify, according to siphonage, bitumen level in the float bowl 11 is identical with liquid level in the asphalt storage tank 20 all the time, can embody the accuracy of bitumen level at any time, when liquid level in the asphalt storage tank 20 rose, 13 of floats rose thereupon, 7 on transition weight affects with gravity and descends, and transition weight 7 drives weight pointers 12 by steel rope 6 and rises synchronously with float 13.When should liquid level descending, weight pointer 12 descends synchronously with float 13.Weight pointer 12 can demonstrate the height of tank level by the scale on the C shaped steel 14 4 exactly in the C shaped steel 14 inner chamber perpendicular movements that scale 4 is arranged.

The utility model processing ease can accurately show innage, and is convenient and practical, can satisfy the needs of highway engineering construction, is suitable for industry and applies.
