Abstract
The utility model relates to a vacuumizing device. A four-way unit is fixed in a cylinder; two horizontal joints of the four-way unit are respectively in sealing communication with one ends of front and rear bent bore pipes; the other ends of the front and rear bent bore pipes are respectively in sealing communication with front and rear straight bore pipes; the upper joint of the four-way unit is in sealing communication with a left straight bore pipe through a nipple; the lower joint of the four-way unit is in sealing communication with one end of the nipple; the other end of the nipple extends out of the cylinder in a sealing manner and is in sealing communication with a vacuum valve; and the vacuum valve is in sealing communication with a vacuum pump. The vacuumizing device is simple in structure and high in speed, and bore pipes are hardly blocked.
Description
Technical field
The utility model relates to the device that a kind of vacuum powder pressurized container vacuumizes.
Background technique
The current fast development along with industrial gas industry in world wide, in order to improve transportation, the efficiency of storage of gas and to reduce transportation, storage cost, " liquefied " become one of important directions of industrial gas industry development, the corresponding construction that drives China's low-temperature heat-insulation pressure container.All the time, in the manufacture process of low-temperature heat-insulation pressure container, the problem that vacuumizes in vacuum sandwich space is a technology emphasis and difficult point, especially to the vacuumizing of powder isolation mezzanine space, in evacuation process, there is easily vacuumizing Kong Guanyi and stop up, vacuumize long and vacuum pump of cycle and easily suck the problems such as dust.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of vacuum pumping device, and it is simple in structure, and hole pipe is difficult for stopping up, and speed is fast.
The technical scheme in the invention for solving the technical problem is: fixing four-way in cylindrical shell, two horizontal interfaces of four-way communicate with one end sealing of forward and backward bent hole pipe respectively, the other end of forward and backward bent hole pipe communicates with the forward and backward straight hole seal of tube respectively, the upper interface of four-way communicates with the left straight hole seal of tube by nipple, the lower interface of four-way communicates with one end of adapter sealing, the other end sealing of taking over is stretched out cylindrical shell and is communicated with vacuum valve seals, and vacuum valve communicates with vacuum pump sealing.
1), three straight hole pipes are uniformly distributed along the circumference, and bleed more even, have shortened the time vacuumizing the utlity model has following advantages:; 2), have bleeder hole on bent hole pipe and straight hole tube wall, increased the area of bleeding; 3), straight hole pipe along cylindrical shell length direction extend, go deep into powder isolation layer inside, reduced the resistance of bleeding, avoided the blind area of bleeding, increased the area of bleeding, improved the efficiency vacuumizing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model plan view;
Fig. 2 is the utility model plan view.
Embodiment
As shown in Figure 1, 2, the interior fixing four-way 4 of cylindrical shell 1, two horizontal interfaces of four-way 4 communicate with one end sealing of forward and backward bent hole pipe 8,11 respectively, the other end of forward and backward bent hole pipe 8,11 communicates with forward and backward straight hole pipe 9,10 sealings respectively, the upper interface of four-way 4 communicates with left straight hole pipe 2 sealings by nipple 3, the lower interface of four-way 4 communicates with one end sealing of taking over 5, the other end sealing of adapter 5 is stretched out cylindrical shell 1 and is communicated with vacuum valve 7 sealings, and vacuum valve 7 communicates with vacuum pump (6) sealing.
Described left straight hole pipe 2, forward and backward straight hole pipe 9,10 are distributed in cylindrical shell 1.
The uniform vent of difference (not shown in FIG.) on the wall of described forward and backward straight hole pipe 9,10 and forward and backward bent hole pipe 8,11.
Coated filter screen (not shown in FIG.) on the outer wall of described forward and backward straight hole pipe 9,10 and forward and backward bent hole pipe 8,11.
Described for filter screen copper wire (not shown in FIG.) fixing, prevent that filter screen is loosening.
Described forward and backward straight hole pipe 9,10 and forward and backward bent hole pipe 8,11 are angle steel butt-welding fitting, replace steel pipe, reduce costs.
