Technical Field

The invention relates to glass deep processing equipment, in particular to a vacuum filtering drainage device.

Background

The secondary glass product is deep processed glass, which is a glass product with specific functions and is made by using once-formed plate glass as a basic raw material and adopting different processing technologies according to use requirements. Glass edging, cutting, punching and the like are generally involved, and foreign matters such as cutting fluid glass slag and the like are generally generated in the processing process; chinese utility model patent CN203355690U discloses an automatic drainage device of vacuum system. The automatic drainage device of the vacuum system with the structure only has a filtering function, but has no treatment capacity on the mixture of oil, water, particles and the like generated by filtering, and the air passage is easily blocked or the filtering effect is easily influenced after a long time; the customer needs to arrange a complex gas path and manually disassemble the filter for draining water regularly, which is very troublesome; the production efficiency of the equipment is reduced, thereby limiting the application range of the equipment.

Disclosure of Invention

The invention aims to provide a vacuum filtering drainage device, which can overcome the defects of the prior art and can realize automatic discharge of filter residues.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows.

The utility model provides a vacuum filtration drainage device, includes the shell, is provided with air inlet and gas outlet on the shell, installs the filter core between air inlet and the gas outlet, the drainage jar is installed to the shell bottom, and drainage jar top is linked together through flexible rubber hose and shell, and the flexible rubber hose bottom is linked together with the wash port, and drainage jar lateral wall is connected with the air pressure regulating valve.

Preferably, the top of the rubber hose is provided with a partition board, the partition board is in clearance fit with the rubber hose, the partition board is fixed on the inner wall of the shell, a plurality of meshes are uniformly arranged on the partition board, the bottom surfaces of the meshes are hinged with baffle plates, and the baffle plates are connected with the partition board through springs.

Preferably, an extension plate is fixed on the edge of the partition plate, a rubber inserting plate is fixed on the top of the extension plate, bristles are fixed on the top of the rubber inserting plate, and when the baffle plate rotates upwards, the rubber inserting plate is inserted between the baffle plate and the meshes.

Preferably, a flange is fixed to the inner side of the upper edge of the mesh.

Preferably, the rubber hose is wrapped with a wire mesh layer.

Preferably, the center of the filter element is connected with a fixing bolt in a penetrating way, and the fixing bolt is connected to the top of the shell.

Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: according to the invention, the air pressure in the drainage cylinder is regulated through the air pressure regulating valve, when the air pressure is increased, the rubber hose is extruded and closed, the drainage channel is closed, the air flow containing impurities enters the shell from the air inlet, the air is filtered by the filter element and then is discharged from the air outlet, and the impurities are retained in the shell; when the air pressure is reduced, the rubber hose expands outwards under the action of the elastic restoring force of the rubber hose, the drainage channel is opened, and moisture and impurities are discharged through the rubber hose under the action of the gravity of the rubber hose. Because the inside and the outside of the shell have larger air pressure difference at the moment when the rubber hose is opened, the moisture and the impurities can be pushed upwards by the external high air pressure, and the filter element is easy to pollute. In order to solve the problem, a clapboard is arranged above the rubber hose, when external high-pressure airflow enters the shell, the clapboard is pushed upwards to temporarily seal the meshes, thereby avoiding the pollution of water and impurities to the filter element through the clapboard. When the air pressure difference between the inside and the outside of the shell is reduced, the baffle is gradually opened, so that drainage is realized. The extension board is used for reducing moisture and impurities from being attached to the meshes, and the bristles are used for cleaning the meshes. When water flows downwards from the upper part of the clapboard, the water flows downwards along the flange, so that the contact area of water and impurities on the inner side of the mesh can be reduced, and the attachment amount on the inner side of the mesh is reduced. The fixed mode of filter core can improve the impact resistance to the atmospheric pressure difference of filter core.
