Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
The utility model provides a precision filter, includes top seal's last barrel 1 and bottom seal's lower barrel 2, wherein 1 both sides of last barrel are provided with air inlet 3 and gas outlet 4 respectively:
a support ring 5 for separating the air inlet 3 from the air outlet 4 is obliquely arranged in the upper barrel 1, wherein a filter cartridge 6 extending into the lower barrel 2 is arranged in an opening of the support ring 5, and the upper end and the lower end of the filter cartridge 6 are arranged in an open manner;
the bottom in the lower barrel 2 is provided with a filling part 7 with the top end in a horizontal state, wherein the top end of the filling part 7 is provided with a supporting barrel I8 positioned in an opening of the filter barrel 6, the top end of the supporting barrel I8 is vertically provided with a plurality of groups of support rods 9, a filter layer 10 positioned in the filter barrel 6 and in a cylindrical structure is sleeved outside the supporting barrel I8 and the support rods 9, and the filter layer 10 is made of filter materials used in the current market;
the top is provided with a supporting cylinder II11 in the opening of filter layer 10, wherein is provided with the pole 13 that hangs who is connected with supporting cylinder II11 on the interior roof of upper barrel body 1, and supporting cylinder II11 lateral wall bottom still is provided with the draw-in groove 12 that is used for holding vaulting pole 9 top.
In this embodiment, the bottom end of the filter cartridge 6 is closely attached to the top end surface of the filling part 7, wherein a rubber sealing layer is adhered to the top end surface of the filling part 7.
When the filter cartridge is used, the filter layer 10 is sleeved on the support cylinder I8 and the support rod 9, then the upper cylinder body 1 and the lower cylinder body 2 are folded, so that the filter layer 10 slides into the filter cartridge 6, the support cylinder II11 slides into the opening at the top of the filter layer 10, and the top end of the support rod 9 slides into the corresponding clamping groove 12, the filter layer 10 is further separated through the support cylinder I8, the support rod 9 and the support cylinder II11, and the filter cartridge 6 wraps the filter layer 10 to prevent the filter layer 10 from bulging outwards, so that the filter layer 10 is clamped and shaped to prevent the filter layer 10 from moving, and the filter layer 10 is not easily influenced by gas blowing to deform and finally influences the filtering effect when filtering gas.
Wherein gas enters the upper cylinder body 1 through the gas inlet 3 and flows into the opening of the filter layer 10 through the opening of the support cylinder II11, then flows into the lower cylinder body 2 through the filter layer 10 and the pore diameter of the filter cylinder 6, finally flows into the upper cylinder body 1 and is discharged from the gas outlet 4, and thus the gas is filtered through the filter cylinder 6 and the filter layer 10.
When the filter layer 10 needs to be cleaned, only the lower cylinder body 2 and the upper cylinder body 1 need to be separated, so that the filter layer 10 can slide down from the filter cartridge 6 and the support cylinder II11, and then the filter layer 10 can be taken down from the support cylinder I8 and the support rod 9 to be cleaned or replaced.
Preferably, the bottom of the lower cylinder 2 is provided with an exhaust pipe 14 which penetrates through the filling part 7 and extends into the supporting cylinder I8, wherein the top end of the exhaust pipe 14 is higher than the top end level of the filling part 7.
Preferably, the upper end and the lower end of the supporting cylinder II11 are both provided with notches 15 in an inclined manner, wherein the upper and the lower sets of notches 15 are arranged in parallel with the supporting ring 5. Therefore, the problem that the gas introduced from the gas inlet 3 is blocked by the side wall of the support cylinder II11 and finally the gas smoothly flows into the openings of the support cylinder II11 and the filter layer 10 is prevented from being influenced because the support cylinder II11 extends to the outer side of the top of the support ring 5.
Preferably, the edge of the top edge of the stay bar 9 and the edge of the outer edge of the bottom of the support cylinder II11 are both provided with rounded corners. The round angle is rounded to facilitate the support rod 9 to slide into the clamping groove 12 and the bottom end of the support barrel II11 to slide into the top opening of the filter layer 10.
As a preferable scheme, the cross section of the stay bar 9 is arc-shaped, wherein the outer arc wall of the stay bar 9 and the outer arc walls corresponding to the support cylinder I8 and the support cylinder II11 are in the same vertical plane, the top end of the stay bar 9 is screwed with a locking bolt the tail end of which is inserted into the filter layer 10, and a groove for accommodating the head of the bolt is formed on the inner side wall of the stay bar 9. The filter layer 10 is prevented from sliding on the support rod 9 in a bolt locking mode, and therefore the problem that the filter layer 10 slides on the support rod 9 to influence the installation or taking-out work of the filter layer 10 in the process of installing the filter layer 10 in the filter cylinder 6 or in the process of taking the filter layer out of the filter cylinder is solved.
As a preferred scheme, the side wall of the upper barrel body 1 is provided with a drain pipe, wherein the drain pipe is arranged on the side wall of the upper barrel body 1 above the bottommost end of the support ring 5, two sides of the top end of the upper barrel body 1 are also respectively provided with two groups of purging pipes in an inclined and downward manner, and the two groups of purging pipes are respectively arranged towards the air inlet 3 and the air outlet 4. Then, after the lower barrel 2 is detached, the upper barrel 1 above the support ring 5 needs to be cleaned, gas is introduced into two sides of the upper barrel 1 above the support ring 5 through the purging pipe, so as to purge the top of the upper barrel 1, and then impurities and gas can be discharged through the opening of the support ring 5, or the impurities obtained through purging flow to the bottommost end of the top of the support ring 5 and are discharged through the drain pipe.
The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
