the mounting shell is internally provided with a filter element, the filter element is of a hollow structure with the top closed, and the bottom of the filter element is clamped on a filter element mounting flange on the inner side of the vacuum flange mounting port, so that the filter element is coaxial with the vacuum flange mounting port.
In a preferred embodiment of the present invention, the filter element is a hollow cylindrical structure with a closed top.
In a preferred embodiment of the present invention, the mounting housing is made of stainless steel.
In a preferred embodiment of the present invention, the vacuum flange mounting port is mounted with a first vacuum quick release flange.
In a preferred embodiment of the present invention, a second vacuum quick-release flange is installed on the filtering inlet.
The beneficial effects of the utility model reside in that:
the utility model discloses a filter fineness can be improved to the structure, and the renew cartridge is more convenient, convenient to use and increase the inside components and parts of vacuum pump and the life of accurate structure.
Drawings
Fig. 1 is a schematic structural view (front view) of the present invention.
Fig. 2 is a schematic structural diagram (bottom 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 obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The vacuum filter 100 shown in fig. 1 or 2 includes a stainless mounting housing 110 for mounting other components, the mounting housing 110 has a closed top end, a vacuum flange mounting opening 111 is formed at a lower portion of the mounting housing 110, a filtering inlet 112 is formed at a side portion of the mounting housing 110, a vacuum quick-release flange 120 is mounted on the vacuum flange mounting opening 111 for connecting a vacuum pump (not shown), and a vacuum quick-release flange 130 is mounted on the filtering inlet 112 for connecting an external device (not shown).
The cylindrical filter element 140 is mounted on the filter element mounting flange 111a inside the vacuum flange mounting port 111, the cylindrical filter element 140 is of a hollow structure with a closed top, and the bottom of the cylindrical filter element 140 is clamped on the filter element mounting flange 111a inside the vacuum flange mounting port 111, so that the cylindrical filter element 140 is coaxial with the vacuum flange mounting port 111.
Because of possessing the above structure, the utility model discloses a theory of operation lies in:
the material to be filtered enters the vacuum filter 100 from the filtering inlet 112, and the cylindrical filter element 140 of the present invention realizes the cyclone separation: the material to be filtered continuously contacts the cylindrical filter core 140 to be filtered until the final filtered product enters a vacuum pump (not shown in the figure) from the vacuum flange mounting port 111, and micro-pores on the cylindrical filter core 140 intercept micro-particles, so that the filtering precision and the filtering effect are improved.
The installation shell 110 is made of stainless steel materials, so that the installation shell is attractive and durable; during maintenance, only the cylindrical filter element 140 needs to be replaced. The vacuum flange mounting port 111 and the filtering inlet 112 are provided with KF vacuum quick-release flanges which can be directly connected with the inlet of a vacuum pump, so that the use is convenient.
