Description

Saw blade sand blasting box air filtering system

Technical Field

The utility model relates to the technical field of saw blade processing equipment, in particular to an air filtering system of a saw blade sand blasting box.

Background

After the saw blade is subjected to heat treatment, the saw blade is subjected to sand blasting treatment, and the sand blasting adopts high-pressure air to spray the sprayed material onto the surface of the saw blade to be treated at a high speed, so that the surface of the saw blade obtains a certain cleanliness and different roughness, and meanwhile, the stress of the saw blade is eliminated, and the mechanical property of the surface of a workpiece is improved.

When the sand blasting equipment works, high-pressure gas forms high-speed jet flow with sand grains in the sand bin through the spray gun, and sand blasting treatment is carried out on the surface of the saw blade. Because high-pressure gas is flushed into the sand blasting equipment, the air pressure in the sand blasting equipment is increased, and an air outlet is needed to be arranged, so that the air pressure inside and outside the sand blasting equipment is balanced. Since sand particles are diffused in the sand blasting equipment, a filter screen is required to be arranged at the air outlet in order to prevent the sand particles from escaping from the air outlet to the external environment and polluting the external environment. The filter screen of current sand blasting equipment air outlet department is all fixed to be set up, is blockked up the filtration pore by the sand grain easily in the filter screen use, if not in time clear up, the atmospheric pressure in the sand blasting equipment can rise gradually, influences the processing of saw blade, and the filter screen is fixed to be set up on sand blasting equipment, and the staff need clear up the filtration pore against the air current, and is very inconvenient.

Disclosure of Invention

The technical problems to be solved by the utility model are as follows: in order to overcome the defects that in the prior art, filter screens at air outlets of sand blasting equipment are fixedly arranged, filter holes are easily blocked by sand grains in the use process of the filter screens, and if the filter screens are not cleaned timely, the air pressure in the sand blasting equipment can be gradually increased to influence the processing treatment of saw blades, the utility model provides an air filtering system of a saw blade sand blasting box.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a saw blade sandblast case air filtration system, includes the box and locates the sand silo on the box, be equipped with a plurality of spray guns in the box, the spray gun through the sandblast pipe with sand silo intercommunication, still be connected with the air compressor machine on the sandblast pipe, be equipped with a plurality of air outlets on the top or the lateral wall of box, air outlet department is equipped with filter component, filter component includes elastic filter screen and two sector plates, two the sector plate is located on the both sides edge that the air outlet set up relatively, two the sector plate sets up towards box inboard direction, and is parallel to each other, two be equipped with on the both sides wall that the sector plate set up relatively to the curved arc track of box inboard direction, set gradually a plurality of in the arc track elastic filter screen, elastic filter screen inlays the part and the arc track sliding connection of locating in the arc track, be equipped with the bodiness portion of being convenient for promote the elastic filter screen in the arc track on the side that the arc track was kept away from to the elastic filter screen.

The air compressor is used for pressing high-pressure gas into the sand blasting pipe, and after sand grains in the sand bin enter the sand blasting pipe, the sand grains are matched with the high-pressure gas to form high-speed jet flow from the spray gun, and the surface of the saw blade is subjected to sand blasting treatment; through setting up filter component in air outlet department, set up the arc track on two sector plates, make the elastic filter screen that locates in the arc track be the arch, the elastic filter screen is crooked to the box in, when the air current that the reply is mingled with the sand grain, guarantees the structural strength of elastic filter screen. When the filter holes of the elastic filter screen are blocked, a worker can take out the clean elastic filter screen, insert the elastic filter screen from one side of the arc-shaped track, eject the blocked elastic filter screen from the other side of the arc-shaped track, and when the elastic filter screen is replaced, sand grains do not escape from the air outlet to the external environment. The replaced elastic filter screen is convenient for a worker to clean sand grains in the filter holes; the end part of the elastic filter screen is provided with a thickening part which is used for facilitating the mutual pushing between the elastic filter screens in the arc-shaped track.

Further, in order to prevent gaps from occurring between the elastic screens, which would cause sand to blow out of the outside of the box, the thickening is made of magnets.

Further, a rolling brush for cleaning the filtering holes of the elastic filter screen is arranged on the side surface of the elastic filter screen, which faces the outer side of the box body, the rotation center of the rolling brush handle is arranged on the circle center where the arcs of the two arc-shaped tracks are located, and the motor for driving the handle to rotate forward or reversely is connected to the handle in a transmission mode.

Some elastic filter screens which do not need to be detached for cleaning can be cleaned by adopting a motor to drive the brush handle to rotate and attaching the brush handle on the surface of the elastic filter screen.

Further, a wind measuring ribbon is arranged at the air outlet. The staff judges the air outlet size of the air outlet according to the fluttering amplitude of the air-measuring ribbon, so that whether the elastic filter screen is blocked or not is known, and the rolling brush is started or the elastic filter screen is replaced, so that normal air outlet and exhaust are ensured.

Further, in order to prevent fine sand grains from being blown out of the box body from the filtering holes of the elastic filter screen, the side surface of the elastic filter screen facing the box body is coated with a sponge layer or a gauze layer.

The beneficial effects of the utility model are as follows: according to the saw blade sand blasting box air filtering system provided by the utility model, the filtering component is arranged at the air outlet, the elastic filter screen is bent into the box body, and the structural strength of the elastic filter screen is ensured when the air flow mixed with sand grains is dealt with; staff inserts from one side of arc track through using clean elastic filter screen, and with the elastic filter screen of jam ejecting from the opposite side of arc track, when accomplishing elastic filter screen and changing, do not have the sand grain from the air outlet loss to external environment in.
