Description

Can be to the flow rate of asphalt weighing device of the uniform heating of pitch

Technical field

The utility model is related to it is a kind of can be to the flow rate of asphalt weighing device of the uniform heating of pitch.

Background technology

In the process of deployment of road construction bituminous paving, pitch use is very frequent, in it of formed asphalt concrete It is preceding, it is necessary to weighed to pitch, measure standard volume and then bonded with mineral pellet integral；Traditional flow rate of asphalt is weighed dress In putting, the heating to pitch is mainly provided with conduction oil coil pipe in asphalt tank body, by conduction oil coil pipe in tank body Pitch is heated；The defects of traditional heating mode is present be：Pitch under normal temperature is solid-state adhesion shape, and mobility is poor, such as Fruit heating-up temperature is low, and its viscosity is larger, is unfavorable for flowing and reflects with other materials, is unfavorable for carrying out uniformly the pitch in tank body Heating, as long as be heated to the condition of high temperature, could continue deep processing after ensureing its mobility.

Utility model content

The technical problems to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided one kind can be uniform to pitch The flow rate of asphalt weighing device of heating.

Technical scheme is used by the utility model solves its technical problem：It is a kind of can be to the pitch of the uniform heating of pitch Flow weighing device, including bearing and pitch tank body, are provided with baffles in the asphalt tank body, and the baffles are by pitch The inner chamber of tank body is separated into superposed heating chamber and the pitch chamber positioned at bottom, and the bottom of the pitch tank body is provided with row Expects pipe connects with pitch chamber；

An at least heating rod is vertically provided with the heating chamber, is wound with the heating rod for pitch circulation Pitch pipe, the upper end connection feed hopper of the pitch pipe, the lower end of the pitch pipe connects with pitch chamber.

Further, heating medium entrance and Crude product input are offered in the heating chamber, the heating medium enters Mouth is located at heating chamber upper end sidepiece, and the Crude product input is located at heating chamber lower end sidepiece.

Further, the quantity of the heating rod is 2, and described heating rod is electrically heated rod.

Further, the both ends of the pitch tank body set supporting baffle respectively, the supporting baffle and bearing upper end it Between be provided with Weighing module.

The beneficial effects of the utility model are：The pitch for the pitch chamber that the utility model flows into passes through on heating rod The heating of pitch pipe, the direction of pitch pipe constantly changes, and pitch can produce the radial motion along pitch pipe in pitch pipe, So make the pitch that is circulated in pitch pipe constantly along pitch pipe radial circulation, make the asphalt temperature that is finally heated unanimously laggard Enter pitch chamber, be uniformly heated pitch.

The design of medium entrance and Crude product input is heated, can be toward injection high-temperature molten salt in heating chamber, by high temperature Fused salt carries out auxiliary heating to pitch pipe, so that pitch pipe is heated again, improves the efficiency of heating surface of whole device, high Temperature molten salt is last to discharge from Crude product input again.

Wherein, 1, bearing, 2, tank body, 3, baffles, 4, heating chamber, 5, pitch chamber, 6, electrically heated rod, 7, pitch pipe, 8, Heat medium entrance, 9, Crude product input, 10, Weighing module.

Embodiment

The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.

As shown in figure 1, a kind of can be to the flow rate of asphalt weighing device of the uniform heating of pitch, including bearing 1 and asphalt tank Body 2, baffles 3 is provided with pitch tank body 2, the inner chamber of pitch tank body 2 is separated into superposed heating chamber 4 by baffles 3 With the pitch chamber 5 positioned at bottom, the bottom of pitch tank body 2 is provided with drainage conduit and connected with pitch chamber 5.

An at least heating rod is vertically provided with heating chamber 4, the pitch pipe for pitch circulation is wound with heating rod 7, the upper end connection feed hopper of pitch pipe 7, the lower end of pitch pipe 7 connects with pitch chamber 5.The quantity of heating rod in the present embodiment For 2, heating rod is electrically heated rod 6.

Heating medium entrance 8 and Crude product input 9 are offered in heating chamber 4, heating medium entrance 8 is located at heating chamber 4 Upper end sidepiece, Crude product input 9 are located at the lower end sidepiece of heating chamber 4.In the present embodiment, heating medium selects high-temperature molten salt.

The both ends of pitch tank body 2 set supporting baffle respectively, and Weighing module is provided between supporting baffle and the upper end of bearing 1 10.DCS control systems are connected, understand the weight of pitch in tank body 2 in real time.

Weighing device of the present utility model, pitch add from upper end feed hopper, into pitch pipe 7, the work production of electrically heated rod 6 Raw high-temperature position pitch pipe 7 conveys heat, and heating medium entrance 8 inputs high-temperature molten salt, and high-temperature molten salt fills whole heating chamber 4, then Heat is conveyed to pitch pipe 7 by high-temperature molten salt, so that pitch is heated properly in flowing, pitch after being heated is from drip Blue or green pipe 7 inputs pitch chamber 5, and the pitch in pitch chamber 5 can be discharged directly from drainage conduit to be used.

Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
