Description

A kind of bituminous pitch storing tank kept the temperature

Technical field

The utility model belongs to bituminous pitch storing tank technical field, and in particular to the bituminous pitch storing tank that one kind can be kept the temperature.

Background technique

The tank body equipment of bituminous pitch storing tank pitch used when referring to for storing road construction, bituminous pitch storing tank is in storage pitch During there is certain heating device, using organic heat-carrying agent (conduction oil) as a heat transfer medium, coal-fired, combustion gas or fuel oil Furnace is heated to for heat source, by hot oil pump forced circulation, pitch using temperature, use when in order to construct.

But there are some defects in the existing bituminous pitch storing tank of existing market, such as added by part in use Thermal can be realized the quick heating of pitch, obtain hard pitch faster, but conduction oil is in the mistake for carrying out local heating As the temperature of pitch is higher and higher in journey, cause the heat waste of conduction oil increasing, and holding vessel internal heat disappears It consumes too fast, makes that asphaltogenic condensation is very fast, and assigned temperature can be just heated to by needing to expend more heats when heating, separately Upon the introduction of heat, high-temperature liquid state pitch assembles the bottom end with holding vessel to outer existing holding vessel, and tapping valve is installed on holding vessel Side, cause pitch discharge not exclusively, cause pitch to waste.

Utility model content

The purpose of this utility model is to provide the bituminous pitch storing tanks that one kind can be kept the temperature, to solve inside existing holding vessel Heat consumption is too fast and pitch discharges incomplete problem.

To achieve the above object, the utility model provides the following technical solutions: the bituminous pitch storing tank that one kind can be kept the temperature, including Outer tank, the side of the outer tank are connected with hot oil pump, and the hot oil pump is connected with hot oil case, the outer tank far from one end of outer tank Interior welds have inner canister, and incubation cavity is formed between outer tank and inner canister, the inside of the incubation cavity is equipped with return pipe, institute The one end for stating return pipe is connect with hot oil case, and the bottom of the outer tank offers drainage hole, and side of the outer tank far from hot oil pump Tapping valve is installed on outer wall, one end of the drainage hole is connect with tapping valve, it is provided with insulating layer on the inner wall of the outer tank, The interior welds of the inner canister have mounting plate, are formed with sump pit at the position of the mounting plate bottom end, and at the top of mounting plate Middle position is welded with local heater, and the bottom end of the sump pit is connect with drainage hole, the inside of the local heater Heating oil pipe is installed, is located at the position of local heater two sides on the mounting plate and offers delivery hole, and mounting plate Inside oil guide pipe is installed, the oil guide pipe is connect with heating oil pipe.

Preferably, the top of the outer tank is equipped with upper cover.

Preferably, the cross sectional shape of the sump pit is right-angled trapezium.

Preferably, there are two the oil guide pipe is arranged altogether, and the one end of two oil guide pipes far from heating oil pipe respectively with return Flow tube is connected with hot oil pump.

Preferably, the inside of the incubation cavity is vacuum state.

The utility model compared with prior art, has the advantages that

(1) the utility model is provided with return pipe, insulating layer and incubation cavity, in initial heating, since condensation pitch adds The absorbed thermal energy of heat is larger, thus initially when inflow return pipe in conduction oil in contained after-heat it is lower, conduction oil at this time It is flowed into hot oil case by return pipe, and in the process distributes after-heat to incubation cavity, one is played to incubation cavity Fixed default effect, as the temperature of pitch in heating process is higher and higher, thus the thermal energy absorbed gradually decreases, and causes back After-heat contained in conduction oil is more and more in flow tube, and after-heat is distributed by the circulation of return pipe with heat dissipation To incubation cavity, so that incubation cavity temperature increases, and it is provided with insulating layer between incubation cavity and outer tank, thus reduces incubation cavity Internal heat is scattered and disappeared, so that incubation cavity generates certain insulation effect to inner canister, so that far from local heater inside inner canister Pitch rate of set reduce, thus reduce in heated asphalt required energy consumption, pass through the phase of return pipe and incubation cavity Mutually cooperation achievees the effect that make full use of conduction oil waste heat, and plays certain guarantor to whole holding vessel by distributing for waste heat Temperature effect, on the one hand reduces the loss of conduction oil heat in heating process, realizes energy-saving heating, on the other hand improves storage The heat insulation effect of tank, so that the bituminous pitch storing of holding vessel and transport better effect.

(2) the utility model is provided with sump pit, delivery hole, tapping valve and drainage hole, in the process for carrying out pitch heating In, hard pitch forms automatic-discharging after liquefaction, flows into for example, the hard pitch after heating passes through the delivery hole on mounting plate In sump pit, and by the inclined-plane of sump pit bottom end be produced from conductance to so that pitch flows in the drainage hole of outer pot bottom, Tapping valve is opened at this time, pitch can be sent to road surface, and in the process, overall structure all has guiding role, so that Hard pitch can be completely exhausted out under the effect of gravity, and in addition one end of return pipe is located at what sump pit was connect with drainage hole At position, so that the interface is able to maintain certain temperature, avoids pitch from condensing in the interface, cause pitch that can not discharge.
