Description
Technical field
The utility model relates to a kind of new structure air heat unit, is specially a kind of mine shaft preventing freeze in winter air heat unit.
Background technology
The existing air heat unit for mine shaft is by import air channel, axial flow blower, and radiator panel, outlet air channel composition, the air heat unit equipment heaviness of this kind of structure, takes up room larger; For guaranteeing the tightness of equipment, the connection between radiator panel mostly is bolted, and in the time that radiator panel breaks down need maintenance, due to the indoor limited space of air heat, assembling-disassembling bolt need take out radiator panel, operating process very complicated; And the mode of existing air heat unit thermal medium turnover radiator is to be directly diverted to each arm of radiator by a house steward, in the time that a certain radiator breaks down need maintenance, remaining radiator cannot continue operation, and winter is very easily freezing, causes unnecessary loss; The position of another existing air heat unit Axial-Flow blower fan is placed on air inlet place, and this kind of arrangement easily leaks out, and causes thermal loss.
Summary of the invention
The utility model, in order to solve existing air heat set structure complexity, overhauls inconvenience and has the technical problem of heat loss, and a kind of air heat unit of new structure is provided.
The utility model is to adopt following technical scheme to realize: a kind of mine shaft preventing freeze in winter air heat unit, comprises cube casing of a horizontal positioned and both ends open; Two ports of cube casing are respectively as cold wind import and hot-blast outlet; It is certain and on it, have the limiting plate of network interface that cube box house is vertically fixed with several intervals near the position of cold wind import along air intake direction, is all placed with a radiator between adjacent limiting plate; Between the limiting plate of the most close cold wind import and cold wind import, be also placed with a radiator; On the top and the bottom sidewall of each radiator, be respectively equipped with a thermal medium import and thermal medium outlet; On cube casing, the sidewall sections corresponding with the radiator sidewall that is provided with thermal medium import and thermal medium outlet comprises multiple movable outside shroudings that arrange, the corresponding radiator of each outside shrouding, exports and on corresponding position, all has hole with the thermal medium import of radiator and thermal medium on outside shrouding; Described each thermal medium import and thermal medium export the hole of all passing on outside shrouding by arm and are connected with heat supply house steward; The junction of heat supply house steward and each arm is equipped with valve; Position near hot-blast outlet in cube casing is fixed with axial flow blower; The air inlet of axial flow blower is towards the cold wind import of cube casing, and the air outlet of axial flow blower is towards the hot-blast outlet of cube casing.
Compared with prior art, the utility model has following characteristics:
(1) radiator " drawer type " assembling.
Cancelled bolt connecting mode between existing radiator, adopted " drawer type " assembling, assembling process only need " push single radiator " corresponding spacing position (be between limiting plate and limiting plate and cold wind import between).In the time that radiator breaks down need maintenance, only fault radiator need be turn-offed with house steward's the valve that is connected, arm is unloaded, and corresponding this radiator outside shrouding is taken off, again by this radiator from corresponding spacing position " extraction ", the intact radiator of replacement " is pushed " to spacing position to be installed arm and outside shrouding can normally to use again, whole process operation is very easy, while having avoided existing air heat unit radiator fault to overhaul, whole radiator panel is taken out to the complicated processes of replacing fault radiator by assembling-disassembling bolt.
(2) air channel is done in a cube casing inner space.
Cancel the import air channel of existing air heat unit, directly by cube casing inner space as air channel, unit inside, this kind of structural design mode reduced device fabrication cost, Maintenance and Repair are convenient, and the air heat unit volume of specification of the same race is obviously less, install, transport, move, disassemble all very convenient; Axial flow blower is placed on hot-blast outlet place, is not easy to leak out, and thermal loss reduces.
(3) adopt arm to join the connected mode of valve
Cancelled the connected mode that existing air heat unit house steward directly connects each arm, joined house steward but thermal medium import adopts arm to join valve again, thermal medium outlet stool is by flange, the equipped house steward's of valve connected mode.This connected mode advantage is: in the time that radiator breaks down, fault radiator can be removed from flange, and be fastened valve, all the other radiators can also access thermal source continue operation, avoided because of winter radiator cannot move the freezing fault causing.
(4) axial flow blower is positioned over air outlet place
Cancel the modes of emplacement that existing air heat unit axial flow blower is placed on air inlet place, axial flow blower is positioned over to air outlet place, this laying method can make whole air heat unit box body interior in negative pressure state, has reduced the thermal loss causing because leaking out.
Further, described hot-blast outlet bore is less than the bore of cold wind import; The axis of axial flow blower is connected hot-blast outlet and cold wind import horizontal center line with cube casing coincides.
Hot-blast outlet is less than cold wind import, can allow air output more concentrated, reduces thermal losses; The axis of axial flow blower coincides with the horizontal center line of cube casing, can make the efficiency of heating surface higher.
