Description
technical field:
The utility model belongs to filter technology field, relates to a kind of high-temperature-resistant gas filter.
background technology:
Existing high-temperature-resistant gas filtration core, substantially be all use from the outside filter type toward internal circulation of filtration core, this kind of mode needs the volume and weight increasing filter, and threaded connection place needs to use flexibility to be wound around seal simultaneously, and flexible seals is at high temperature very easily aging.Existing high-temperature filter cannot change filtration core under the high temperature conditions, and dismounting needs specific purpose tool, and maintenance process is very complicated.
Existing universal high-temperature resistant filter structure as shown in Figure 2, flue gas enters from the gauge inlet port 1 of filter upper cover 12, by the hollow cavity of passage 2 and bracing frame 4, enter the inside of cartridge filter 9, then the inside of filtration core 5 is entered from the outside of filtration core 5, then by outlet passageway 10 Engage of standard outlet 11, thus instrument is entered.The shortcoming of this structure is as follows:
If 1, screw thread place 3 is not wound around flexible seals, then fine dust can pass through the direct Engage of standard gas outlet 11 of thread pitch.
2, filter cylinder 9 upper end and filter upper cover 12 threaded engagement, filter upper cover 12 cooperation place is provided with seal groove 8, is provided with O type circle 6 screw thread place 7 owing to relating to the sealing of O type circle 6 in seal groove 8, requirement on machining accuracy is high, and in actual use procedure, screw thread 7 is at high temperature easily killed, and cannot dismantle.
3, because gas enters inner side, cause volume excessive, be not suitable for installing in narrow space.
Even if under 4 states of not killing at screw thread 7, also need to use specific purpose tool in unloading process, otherwise the excessive filter cartridge 9 of diameter cannot be turned on.
summary of the invention:
The utility model solves the ubiquitous technological deficiency of existing high-temperature filter, and provide a kind of structure simple, volume is little, and cost is low and safeguard high-temperature filter extremely easily.
For solving the problem, the technical scheme of employing is as follows:
A kind of high-temperature resistant filter, mainly comprise filter upper cover, filter lower cover, support filter stand and filtration core, filtration core is located by connecting by support filter stand and filter upper cover, filter is covered with air inlet and interface of giving vent to anger, filter lower cover is sleeved on outside filtration core, also comprise end cover, be sleeved on bottom filter lower cover on end cover, be threaded connection bottom end cover top and support filter stand, filter lower cover bottom be positioned end cover and support between filter stand, and by filter lower cover top and filter upper cover positioning compression; The intake interface of filter upper cover and filtration core inner space, interface of giving vent to anger is communicated with filtration core external cavity.
Further design of the present utility model is:
Filter lower cover top and filter upper cover cooperation place are provided with sealing ring, and sealing circle is located in the seal groove of tops under filter.
Filter lower cover bottom and end cover cooperation place are provided with sealing ring, and sealing circle is located in the seal groove at end cover top.
Described end cover adopts hand to twist end cap, this hand twist end cap top be provided with screw rod and support filter stand bottom screw coordinate, middle part is provided with round platform and coordinates with filter lower cover, and bottom is provided with and clamps wing plate.
The intake interface of filter upper cover is communicated with by the fluting supported on filter stand 7 with filtration core 6 inner chamber.
the utility model compared to existing technology tool has the following advantages:
In the utility model, the installation of all parts is all by realizing with the connection supporting filter stand, easy accessibility.
What the utility model adopted due to gas is filter type from inside to outside, supports the screw thread place of filter stand and the screw thread at end cover place does not need to be wound around flexible seals, and overall volume is little.The sealing load of filter upper cover and filter lower cover junction O type circle is provided by the torsion of end cover, and the sealing load of O type circle is provided by the torsion of end cover equally, so just end cover can be dismantled without the need to special tool(s), realize the quick-replaceable to filtration core.
accompanying drawing illustrates:
Fig. 1 is the utility model high-temperature resistant filter structural representation.
Fig. 2 is existing high-temperature resistant filter structural representation.
In Fig. 1: 1-filter upper cover; 2-(standard) interface of giving vent to anger; 3-tube connector; 4-seal groove; 5-filter lower cover; 6-filtration core; 7-supports filter stand; 8-via hole; 9-O type circle; 10-end cover; 11-O type circle; 12-screw thread; 13-rectangle air slot; 14-O type circle; 15-screwed hole; 16-(standard) intake interface.
detailed description of the invention:
Shown in Fig. 1, high-temperature resistant filter of the present utility model, mainly comprises filter upper cover 1, filter lower cover 5, end cover 10, supports filter stand 7 and filtration core 6.Filtration core 6 is sleeved on and supports on filter stand, and filter lower cover is sleeved on outside filtration core.Filter lower cover 5 top is provided with seal groove, and bottom is provided with via hole 8 and is sleeved on end cover 10, and filter lower cover 5 top and filter upper cover 1 compress.Filter upper cover 1 top is provided with seal groove, built-in O type circle.Seal groove is established at end cover 10 top, in built-in O type.
End cover can adopt hand to twist end cap, and its top is provided with screw rod and coordinates with screw bottom support filter stand, and middle part is provided with round platform and coordinates with filter lower cover, and bottom is provided with clamping wing plate, is suitable for hand and twists or tool ejector.Support filter stand 7 middle and upper part and be provided with fluting (herein for rectangle air slot 13, other shape also can), by intake interface 16 and filtration core 6 inner space.Interface 2 of giving vent to anger is communicated with the cavity between filtration core 6 outside and filter lower cover 5.Filtration core 6 upper end is located by the shoulder bottom filter upper cover 1, and filtration core 6 lower end is located by the shoulder supporting filter stand 7.
