Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

The utility model discloses an air filtering filter element convenient to install.

As shown in fig. 1 to 3, the air filter element convenient to install includes a paper filter element main body 1, and the whole paper filter element main body 1 can be regarded as a cylindrical structure. The both ends of paper filter core main part 1 are connected with first end plate 2 and second end plate 3, and the size of first end plate 2 and second end plate 3 equals, are discoid steel sheet, and second end plate 3 is located directly over first end plate 2. The both ends of paper filter core main part 1 respectively with first end plate 2 and the contact of second end plate 3, paper filter core main part 1 is fixed between first end plate 2 and second end plate 3, and first end plate 2 is used for connecting admission valve 8.

In order to realize the quick installation to paper filter main part 1, turn over relatively 90 at the edge of first end plate 2 and second end plate 3 and be formed with the guard plate, paper filter main part 1 is located inside the guard plate. The first end plate 2 and the second end plate 3 are metal pieces, specifically stainless steel plates, and are stamped and folded through stamping equipment.

Further, a protector 4 for protecting the paper filter element main body 1 is attached between the first end plate 2 and the second end plate 3. Specifically, the protection part 4 is a metal net which is sleeved on the paper filter element main body 1, the outer side of the metal net is attached to the protection plate, and the inner side of the metal net is attached to the paper filter element main body 1. The metal mesh supports the paper filter element main body 1, and can effectively prevent foreign objects from touching the paper filter element main body 1.

In this embodiment, the connection structure of the first end plate 2 and the air inlet valve 8 is that the connection port 5 is installed at the center of one side of the first end plate 2 departing from the second end plate 3, and the connection port 5 is a steel pipe fitting. The connection port 5 may be fixed to the surface of the first end plate 2 by welding.

Similarly, the end of the connecting port 5 can be turned over by 90 ° to form a flange, and fixed on the surface of the first end plate 2 by riveting to increase the strength. In the present embodiment, the connection port 5 is connected to the first end plate 2 by caulking.

The connecting port 5 is used for being sleeved on the air inlet valve 8 interface, and the inner diameter of the connecting port 5 is 0.5-1.0mm larger than the outer diameter of the air inlet valve 8 interface, so that the connecting port 5 and the air inlet valve 8 can be conveniently installed. Install the rubber packing ring between connector 5 and the admission valve 8, in the air compressor use, can continuously produce vibrations, the rubber packing ring plays sealed the time, plays the effect that slows down vibrations.

And an anchor ear 6 for fixing the connecting port 5 on the interface of the air inlet valve 8 is arranged outside the connecting port 5. Specifically, a strip-shaped groove 51 is uniformly formed at one end of the connection port 5 away from the first end plate 2, and the strip-shaped groove 51 is arranged along the length direction of the connection port 5. In the present embodiment, the number of the bar-shaped grooves 51 is four, and four elastic pieces are formed at the connection ports 5. Make the shell fragment to shrink inwards through staple bolt 6, fix connector 5 and admission valve 8.

Specifically, the hoop 6 includes a hoop plate 61, a fastening bolt 62 and a fastening nut 63, the fastening nut 63 is fixed to one end of the hoop plate 61, and the fastening bolt 62 passes through the other end of the hoop plate 61 and is in threaded fit with the fastening nut 63. Also, an installation groove for installing the fastening nut 63 may be formed at one end of the band plate 61. Thus, when the fastening bolt 62 is assembled and disassembled, the fastening nut 63 cannot rotate, and the assembling and disassembling can be conveniently completed only by one hand.

In this embodiment, the fastening bolt 62 may be a hexagon socket head cap screw, so that the maintenance personnel can complete the disassembling and assembling operations in a narrow space.

In addition, the baffle 7 is welded and fixed on the elastic sheet of the connecting port 5, the baffle 7 is distributed on the three elastic sheets, the cross section of the baffle 7 is L-shaped, and the baffle 7 and the connecting port 5 form a placing gap for placing the hoop plate 61. After the hoop 6 is sleeved on the connecting port 5, the hoop plate 61 can be placed in the placing gap. When in use, the baffle 7 can be used for preventing the hoop 6 from separating from the connecting port 5 and also has the purpose of opening the connecting port 5.

The air filter of the existing air compressor basically needs an air filter shell, the shell is fixed on a metal plate of the air compressor after being provided with the air filter, and then the air filter is connected with the air inlet valve 8 through a rubber hose, so that the production cost is increased, and meanwhile, the hidden trouble of quality problem can be caused by adding one more part. The rubber product used in high temperature environment generally has a normal service life of 2-3 years, and the air compressor stock in domestic market is huge, if the life is discarded, the aged rubber pipe not only increases the cost of a user, but also is a great burden for environmental protection.

In this embodiment, the air filter is directly mounted on the air intake valve 8 without using an air filter housing and a connecting rubber hose, which can reduce the production cost, the after-sale maintenance cost and the replacement time. Meanwhile, the use of rubber hoses is reduced, and the environment is also contributed.

The specific implementation principle of the utility model is as follows:

according to the utility model, the paper filter element main body 1 and the two end plates are designed and matched with the protection piece 4 to form the filter element, compared with the prior art, a filter shell is omitted, and the filter element can be directly connected to the air inlet valve 8, so that the cost is saved and the installation is more convenient; the setting of strip type groove 51 on connector 5, the connector 5 of being convenient for takes place deformation, can realize being connected of connector 5 and admission valve 8 through staple bolt 6, and the installation is lighter convenient with the dismantlement, and baffle 7 on the connector 5 when preventing that staple bolt 6 from breaking away from plays the purpose of opening connector 5, and the setting of staple bolt 6 is convenient for use in addition.
