Abstract
The utility model relates to a vacuum exhaust device of a reciprocating tilting bench, which comprises a reciprocating tilting bench, and a vacuum exhaust port of the reciprocating tilting bench is connected with a vacuum pipeline which is connected with a vacuum pump. The utility model is characterized in that the vacuum pipeline is provided with an exhaust vent which is welded with an exhaust pipe, and an outlet of the exhaust pipe is provided with an exhaust valve. The utility model has the advantages that the vacuum exhaust device can remove harmful gas generated in production in time andprevent the product from bulging and bottom leaking so as to improve product quality and qualification rate.
Description
Technical field
The utility model relates to a kind of platform vacuum pumping hardware that back and forth fascinates that uses on Electric Arc Crucible Making-machine.
Background technology
The electric arc crucible is to be the supporting auxiliary product of photovoltaic industry pulling of crystals, and Electric Arc Crucible Making-machine is by heating power supply, lift, back and forth platform three great institutions that fascinate are formed.Wherein adopting vacuum line to be connected to the platform that back and forth fascinates is used to vacuumize, the problem of its existence is: because in process of production, vacuum line is in air-tight state, in case the too high or connecting portion of heating-up temperature occurs slight drainage is arranged, steam or other gas will appear in vacuum line, make product bag occur, leak end phenomenon, reduce the qualification rate of product.
Summary of the invention
The purpose of this utility model is will provide a kind of and can avoid product bag to occur, leak end phenomenon, improves the quality of products and the platform vacuum pumping hardware that back and forth fascinates of qualification rate.
The utility model is achieved in that it comprises the platform that back and forth fascinates, vaccum exhaust outlet place at the platform that back and forth fascinates is connected with vacuum line, vacuum line is connected with vavuum pump, its special character is: be provided with steam vent on vacuum line, be welded with blast pipe at this steam vent place, drain tap be installed in the outlet of blast pipe.
The utility model has the advantages that: because exhaust apparatus has been installed on vacuum line, be in closed condition when vacuumizing, vacuumize and finish the back by the manual unlocking valve, can in time get rid of the pernicious gas that produces in producing, avoid product bag to occur, leaked end phenomenon, thereby improve the quality of products and qualification rate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the table frame 1 that fascinates, the case 2 that fascinates, crucible shaped device 3, vacuum line 4, steam vent 401, vavuum pump 5, blast pipe 6, drain tap 7.
The specific embodiment
As shown in the figure, the utility model has the platform that back and forth fascinates, the platform that back and forth fascinates be by the table frame 1 that fascinates, the rotatable crucible shaped device 3 that fascinates case 2 and be located on the case 2 that fascinates that is located at table frame 1 middle part of fascinating constitutes, vaccum exhaust outlet place on the case 2 that fascinates of the platform that back and forth fascinates is connected with vacuum line 4, vacuum line 4 is connected with vavuum pump 5, on vacuum line 4, be provided with a steam vent 401, be welded with blast pipe 6 at these steam vent 401 places, drain tap 7 be installed in the outlet of blast pipe 6.
