Description

Anticorrosive vacuum pipeline filter capable of gas-liquid backwashing

Technical Field

The utility model relates to an anticorrosive vacuum line filter of ability gas-liquid backwash.

Background

Vacuum pumps such as reciprocating vacuum pumps, rotary vane vacuum pumps, slide valve vacuum pumps, roots vacuum pumps, and the like draw in, compress, and discharge gas by reciprocating or rotating a piston. The advantages are that the vacuum degree of the pump which is newly put into use is relatively high, but the piston is a running part, so the abrasion of the piston can not be avoided, and the working vacuum degree is continuously reduced along with the increase of the maintenance times until the production requirement can not be met.

The filter matched with the existing various vacuum pumps is easy to block or even penetrate because the matched filtering material is generally a metal material or a simple surface filtering structure. And the corrosion resistance function is not provided, so that the inside of the pipeline is rusted, more impurities and dust are generated, and the vacuum pump is damaged. And secondary pollutants are easily generated to cause the damage of the vacuum pump.

SUMMERY OF THE UTILITY MODEL

The utility model provides an above-mentioned technical problem adopted technical scheme as follows: the utility model provides a can anticorrosive vacuum line filter of gas-liquid backwash which characterized in that includes the barrel, the upper portion of barrel forms the intake pipe in one side, and one side relative with the intake pipe sets up the outlet duct, the top of barrel sets up the blowback pipeline, the blowback pipeline on set up anticorrosive blowback valve, the bottom of barrel sets up the drain, the drain on set up the blowback valve, the barrel in set up the filter core. The utility model discloses a side-in side-out mode, the tube coupling of being convenient for, it is fixed more easy to assemble. The valve-equipped back flushing port is reserved, so that compressed air and backwash liquid can be conveniently accessed for back flushing. The design of reserving a drain outlet is convenient for timely removing dust and liquid.

The barrel in set up the mounting panel, the filter core hoist and mount be in the mounting panel on, the lower part that is located the filter core is the dirt cavity that holds of barrel.

The filter core pass through the screw thread and be connected with mounting panel hoist and mount, compress tightly through the sealed pad of silica gel package tetrafluoro and form sealedly, intake pipe inner be connected to the mounting panel to it is sealed with the mounting panel through double seal circle.

And a hastelloy vacuum diaphragm pressure gauge is arranged at the upper part of the cylinder body.

The cylinder body is in a cross structure by combining the air inlet pipe and the air outlet pipe.

The mounting plate is a polytetrafluoroethylene plate.

The utility model discloses the side of intake pipe and outlet duct inclines out the structure, more is favorable to the customization of pipeline size, and the installation is more fastened. The valve-equipped back flushing port is reserved, so that compressed air and backwash liquid can be conveniently accessed for back flushing. The design of reserving a drain outlet is convenient for timely removing dust and liquid. The filter core adopts the design of hoist and mount structure, and granule and dust are effectively subsided to the accessible action of gravity.

Drawings

Fig. 1 is a schematic view of the present invention.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention.

As shown in figure 1, the anticorrosive vacuum pipeline filter capable of gas-liquid backwashing comprises a barrel body, wherein an air inlet pipe 3 is formed at one side of the upper portion of the barrel body 10, an air outlet pipe 6 is arranged at one side opposite to the air inlet pipe, a back flushing pipeline is arranged at the top of the barrel body, an anticorrosive back flushing valve 5 is arranged on the back flushing pipeline, a drain outlet is arranged at the bottom of the barrel body, a drain valve 13 is arranged on the drain outlet, a filter element 9 is arranged in the barrel body, an inlet loop flange 1 and a sleeve flange 2 are arranged on the air inlet pipe, a detachable loop flange 7 is arranged on the air outlet pipe, polytetrafluoroethylene powder is sprayed inside the barrel body, and the barrel body is sintered at high temperature to form a coating 11 attached to. The barrel in set up the mounting panel, the filter core hoist and mount be in the mounting panel on, be located the lower part of filter core and be the dirt cavity 12 that holds of barrel. The large dust holding cavity can ensure enough holding space for dust and oil sludge.

The filter core pass through the screw thread and be connected with 8 hoists of mounting panel, it is sealed to compress tightly through the sealed pad of silica gel package tetrafluoro and forms sealedly, intake pipe inner be connected to the mounting panel to it is sealed with the mounting panel through double seal circle. The filter core adopts the design of hoist and mount structure, and granule and dust are effectively subsided to the accessible action of gravity. Effectively prevent that the fatlute that dust and liquid produced from gathers to adhere to on the pipeline to jam and damage the vacuum pump. And a hastelloy vacuum diaphragm pressure gauge 4 is arranged at the upper part of the cylinder body. The reverse cleaning time of the filter element can be judged in time by effectively observing the vacuum degree condition. The cylinder body is combined with the air inlet pipe and the air outlet pipe to form a cross structure. The upper half part and the lower half part of the cylinder body are sealed and fastened by adopting a quick-opening lifting ring bolt group.
