Description
[technical field]
The utility model relates to a kind of Powdex filter, is specifically related to a kind of Powdex filter of using in petrochemical industry, belongs to the petrochemical equipment technical field.
[background technology]
The Powdex filter of prior art mostly is and is directly installed on the logical structure of two on the sampling slip, owing to need corrosion-and high-temp-resistant, is generally full-closed structure.This filter element area is little, and filter efficiency is low, and filter core can't clean, also can't change, and the filter that normal operation just can only more renew about 3 months, and also this filter is installed in cat head more, and inconvenient during replacing, potential safety hazard is arranged.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of structure improved Powdex filter that has, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model be to provide a kind of simple in structure, filter efficiency is high, long service life and change easily Powdex filter.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of Powdex filter, and it comprises shell, filter core, end cap, pull bar, pressing plate and rotating shaft; Wherein, be provided with a sample entrance and sample outlet in described outer casing underpart, shell upper is provided with a compress wind entrance and compress wind outlet; Described end cap is positioned at the top of shell; Described filter core is installed on the end cap and is contained in the shell; Described rotating shaft one end is connected on the end cap; Described pressing plate is sheathed on the rotating shaft; The two ends of described pull bar are connected in respectively on shell and the pressing plate.
Powdex filter of the present utility model further is set to: be provided with a slag-drip opening in the bottom of described shell.
Powdex filter of the present utility model further is set to: be provided with a sample tap in the top of described shell.
Powdex filter of the present utility model further is set to: described pressing plate is provided with a pair of hole clipping, and each hole clipping comprises a macropore and an aperture, and large bore dia is greater than the pull bar diameter, and hole diameter is less than the pull bar diameter.
Compared with prior art, the utlity model has following beneficial effect: the filter core area of Powdex filter of the present utility model is large, and filter efficiency is high, and filter core can clean by blowback, can be extended to the service life of filter core about 1 year, and can be very easily renew cartridge more.

[specific embodiment]
See also Figure of description 1 to shown in the accompanying drawing 6, the utility model is a kind of Powdex filter, and it is formed by a few part assemblings such as shell 12, filter core 7, end cap 8, pull bar 9, pressing plate 10 and rotating shaft 11.
Wherein, be provided with a sample entrance 1 and sample outlet 2 in described shell 12 bottoms, shell 12 tops are provided with a compress wind entrance 4, compress wind outlet 5 and one sample tap 3.Further, be provided with a slag-drip opening 6 in the bottom of described shell 12.
Described end cap 8 is positioned at the top of shell 12.
Described filter core 7 is installed on the end cap 8 and is contained in the shell 12, and it is used for flue gas is filtered.
Described rotating shaft 11 1 ends are connected on the end cap 8, thereby can regulate the position of filter core 7.
Described pressing plate 10 is sheathed on the rotating shaft 11, which is provided with a pair of hole clipping 13, and each hole clipping 13 comprises a macropore 14 and an aperture 15, and macropore 14 diameters are greater than pull bar 9 diameters, and aperture 15 diameters are less than pull bar 9 diameters.
The two ends of described pull bar 9 are connected in respectively on shell 12 and the pressing plate 10, and the one side is provided with a breach (not label), thereby make this pull bar 9 slip into aperture 15 and locate from macropore 14.
The operation principle of Powdex filter of the present utility model is as follows: filter core 7 is screwed be installed on the end cap 8 and put into shell 12, then by rotation rotating shaft 11 filter core 7 is selected to put in place, and snap in pull bar 9 in the hole clipping on pressing plate 10 13.Sample tap 3 is connected to the sample analysis branch road by ferrule fitting, and compress wind entrance 4 passes into high-pressure blast, the slag-drip opening 6 slag equipment that runs in.Closes compression wind entrance 4, compress wind outlet 5 and slag-drip opening 6 can carry out sampling filtering, as shown in Figure 3.After using a period of time, in the time of need to purging cleaning to filter core 7, close sample inlet 1 and sample export 2, open compress wind entrance 4, compress wind outlet 5 and slag-drip opening 6, can purge filter core 7 and clean, impurity enters residue extraction mechanism from slag-drip opening 6, as shown in Figure 4.When filter core 7 long-time uses needed to change, rotary pressure plate 10 made it throw off pull bar 9, can filter core 7 be proposed the filter core 7 that more renews by rotating rotating shaft 11.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
