Description

Pure mechanical vacuum pumping equipment

Technical Field

The utility model relates to a vacuum apparatus technical field specifically is a pure mechanical vacuum pumping equipment.

Background

The vacuum pump refers to a device or equipment for obtaining vacuum by pumping a pumped container by using a mechanical, physical, chemical or physicochemical method. In general, a vacuum pump is a device for improving, generating and maintaining a vacuum in a certain closed space by various methods. After the sleeving is finished, the interlayer is vacuumized, and fine particles cannot escape into the vacuumizing equipment while the interlayer is vacuumized. The existing vacuum-pumping device is formed by drilling a certain number of small holes on a stainless steel pipe with enough drift diameter and then wrapping the surface of the steel pipe with glass fiber cloth. The structure can meet basic use requirements, but has certain limitation, the gas circulation area of the vacuumizing device through the small holes is limited, so that the vacuumizing efficiency is low, a large amount of vacuumizing time is wasted, vacuumizing equipment and stations are occupied for a long time, and the vacuumizing device is a short plate of the whole production line.

SUMMERY OF THE UTILITY MODEL

In view of the deficiencies and drawbacks of the prior art, an object of the present invention is to provide a purely mechanical vacuum pumping apparatus.

In order to solve the technical problem, the utility model discloses a following technical scheme: the pure mechanical vacuum pumping equipment comprises a flange, and further comprises an upper plate, a middle plate and a lower plate which are arranged in sequence from top to bottom and are parallel to each other, wherein the circumferential edges of the upper plate, the middle plate and the lower plate are fixed through a plurality of uniformly distributed rib plates, a plurality of through holes are formed in the upper plate, the middle plate and the lower plate, a plurality of holes are formed in the rib plates, a glass fiber cloth bag is sleeved on the periphery of each rib plate, and the lower plate is fixed on the flange.

As a further improvement of the utility model, the through-hole quantity and the position on upper plate, medium plate and the hypoplastron correspond to each other.

As a further improvement of the utility model, the glass fiber cloth bag is externally provided with binding wires at intervals.

As a further improvement of the utility model, a strip hole is arranged between the upper plate and the lower plate which are adjacent to each other on the rib plate.

Compared with the prior art, the utility model discloses the beneficial effect who has does: when the vacuum pumping device is used, the end of the vacuum pumping pipeline wound on the glass fiber cloth bag extends into the interlayer of the container, the flange is connected with the vacuum pumping device, during vacuum pumping, gas in the interlayer penetrates through the glass fiber cloth bag and is sucked away by the vacuum pumping device in a large quantity, fine particles are blocked by the glass fiber cloth bag and are left in the interlayer, the rib plate plays a role in fixing and strengthening, and the plurality of holes formed in the rib plate increase the gas circulation surface.

Drawings

The invention will be further described with reference to the accompanying drawings:

FIG. 1 is a schematic view of a half-section structure of a pure mechanical vacuum-pumping device of the present invention;

in the figure: 1 flange, 2 glass fiber cloth bags, 3 upper plates, 4 middle plates, 5 lower plates, 6 through holes, 7 rib plates, 8 holes and 9 binding wires.

Detailed Description

In order to make the technical solution and the advantageous effects of the present invention more clear, the present invention will be further described in detail with reference to the following embodiments.

Fig. 1 is the utility model relates to a pure mechanical evacuation equipment semi-section structure sketch map, including flange 1, still include from the top down upper plate 3, medium plate 4 and hypoplastron 5 that set gradually, are parallel to each other, the circumferential edge reason of upper plate 3, medium plate 4 and hypoplastron 5 is fixed through a plurality of evenly distributed's gusset 7 be equipped with a plurality of through-holes 6 on upper plate 3, medium plate 4 and the hypoplastron 5 be equipped with a plurality of bar holes 8 on the gusset 7 the peripheral glass fiber sack 2 that embolias of gusset 7, the outer interval of glass fiber sack 2 sets up ties up silk 9, and hypoplastron 5 is fixed on flange 1.

The number and the positions of the through holes 6 on the upper plate 3, the middle plate 4 and the lower plate 5 correspond to each other, and a strip hole 8 is arranged on the rib plate 7 and between the adjacent upper plate and the adjacent lower plate.

When the device is used, the end of the vacuumizing pipeline of the glass fiber cloth bag 2 is wound to extend into the interlayer of the container, the flange 1 is connected with vacuumizing equipment, during vacuumizing, gas in the interlayer penetrates through the glass fiber cloth bag 2 and is greatly sucked away by the vacuumizing equipment, fine particles are blocked by the glass fiber cloth bag 2 and are left in the interlayer, the rib plate 7 plays a role in fixing and strengthening, and the plurality of holes 8 formed in the rib plate 7 increase the gas circulation area.
