Abstract

Baffles can be provided with asphalt tank body to the flow rate of asphalt weighing device of the uniform heating of pitch, including bearing and pitch tank body the present invention relates to a kind of, the inner chamber of pitch tank body is separated into superposed heating chamber and the pitch chamber positioned at bottom by baffles；It is provided with heating chamber and is vertically provided with least one heating rod, pitch pipe is wound with heating rod, the upper end of pitch pipe connects feed hopper, and the lower end of pitch pipe connects with pitch chamber.The pitch in the pitch chamber that the present invention is flowed into is by the pitch pipe heating on heating rod, the direction of pitch pipe constantly changes, pitch can produce the radial motion along pitch pipe in pitch pipe, so make the pitch circulated in pitch pipe constantly along pitch pipe radial circulation, final heated asphalt temperature is unanimously entered pitch chamber afterwards, be uniformly heated pitch.

Description

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

Technical field

The present invention relates 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 using very frequently, formed asphalt concrete it 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 of pitch is mainly and is provided with conduction oil coil pipe in asphalt tank body, by conduction oil coil pipe in tank body Pitch is heated；Traditional heating mode exist defect 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 other materials reflection, is unfavorable for carrying out uniformly the pitch in tank body Heating, as long as be heated to the condition of high temperature, it is ensured that deep processing could be continued after its mobility.

The content of the invention

The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided one kind can be to the uniform heating of pitch Flow rate of asphalt weighing device.

The technical solution adopted for the present invention to solve the technical problems is：It is a kind of can be to the flow rate of asphalt of the uniform heating of pitch Weighing device, including bearing and pitch tank body, are provided with baffles in the asphalt tank body, the baffles are by pitch tank body Inner chamber be separated into superposed heating chamber and the pitch chamber positioned at bottom, the bottom of the pitch tank body is provided with drainage conduit Connected with pitch chamber；

It is provided with the heating chamber and is vertically provided with least one heating rod, is wound with the heating rod for pitch circulation Pitch pipe, the pitch pipe upper end connection feed hopper, 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 two ends of the pitch tank body are respectively provided with supporting baffle, the supporting baffle and bearing upper end it Between be provided with Weighing module.

The beneficial effects of the invention are as follows：The pitch in the pitch chamber that the present invention is flowed into is by the pitch pipe on heating rod Heating, the direction of pitch pipe constantly changes, and pitch can produce the radial motion along pitch pipe in pitch pipe, so make The pitch of circulation makes final heated asphalt temperature unanimously enter pitch afterwards constantly along pitch pipe radial circulation in pitch pipe Chamber, is uniformly heated pitch.

The design of heating medium entrance and Crude product input, 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.

Brief description of the drawings

The present invention is further described below in conjunction with the accompanying drawings.

Fig. 1 is the schematic diagram of weighing device of the present invention；

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

Specific embodiment

Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side Formula illustrates basic structure of the invention, therefore it only shows the composition relevant with the present invention.

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 Baffles 3 are provided with body 2, 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 is connected with pitch chamber 5.

It is provided with heating chamber 4 and is vertically provided with least one heating rod, is wound with heating rod for pitch circulation Pitch pipe 7, the upper end connection feed hopper of pitch pipe 7, the lower end of pitch pipe 7 connects with pitch chamber 5.Heating rod in the present embodiment Quantity is 2, and 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 is located at the lower end sidepiece of heating chamber 4.In the present embodiment, heating medium selects high-temperature molten salt.

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

Weighing device of the invention, pitch is added from upper end feed hopper, and into pitch pipe 7, the work of electrically heated rod 6 produces high Potential temperature pitch pipe 7 conveys heat, the heating input high-temperature molten salt of medium entrance 8, the whole heating chamber 4 of high-temperature molten salt filling, then relies on High-temperature molten salt conveys heat to pitch pipe 7, so that pitch is heated properly in flowing, pitch after being heated is from pitch pipe 7 input pitch chambers 5, the pitch in pitch chamber 5 can be used directly from drainage conduit discharge.

With above-mentioned according to desirable embodiment of the invention as enlightenment, by above-mentioned description, relevant staff is complete Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
