Abstract
The utility model discloses a kind of filter disc for separating paste state bed reactor dead catalyst, including the more sub- coaxial settings of filter disc, described sub- filter disc includes filter disc and disk hoop, described disk hoop is coated on the outward flange of filter disc, also include supporting plate and a pair of ring flanges, flange hole is provided among described supporting plate, supporting plate is arranged on the centre of filter disc, supporting plate size is identical with filter disc size, and multiple support columns are evenly distributed with described supporting plate upper surface and lower surface.The utility model increases anchor ear in the outside of filter disc, so that filter disc still can guarantee that intensity in the case where high-speed rotation works, filter screen is not indeformable damaged；Secondly multiple circular ring-type seal grooves are increased on mounting flange end face, so that sealing is more stable；Strengthening version and support column finally are set in the by-level of filter disc filter screen, so that will not be by generation deformation during the gravitational thrusts such as filter residue so as to the phenomenon that should not be come off during the use of filter screen.
Description
Technical field
It the utility model is related to catalyst filter disc technical field, more particularly to a kind of useless catalysis of separation paste state bed reactor
The filter disc of agent.
Background technology
At present, in domestic Reppe legal system BDO techniques, intermediate product butynediols is by formalin and second
Alkynes gas generates in the presence of powdered copper-bismuth catalyst.Its reactor belongs to stirring autoclave slurry reactor, belongs between half
Have a rest semicontinuous type mode of operation, fresh catalyst is added after reactor, as the carry out catalyst granules of reaction is damaged and
Activity reduces, and according to the index quantifications such as organic loss, solid content addition raw catelyst is chemically examined, discharges dead catalyst, and is excluding
Used in the process of waste catalyst to filter disc be critical elements, sub- filter disc is coaxial is close to set i.e. by more for existing filter disc
Formed in rotating shaft, and sub- filter disc fastens the filter disc body formed by two panels circular filter screen, and set among sub- filter disc body logical
Hole, for being fixed with rotating shaft, sealing strip then is used in sub- filter disc body and shaft contacts portion, even if sub- filter disc body and rotating shaft
Sealing, makes the two fixed setting again.But existing filter disc is in use because long-term high speed rotates, in material waste residue and
In the presence of centrifugal force, filter disc body can produce low, the easily leakage that filter disc precision be present, low intensity, and anchor ear is damaged and come off existing
As having had a strong impact on production efficiency.
Utility model content
The purpose of this utility model is to provide a kind of filter disc for separating paste state bed reactor dead catalyst, it is possible to increase waste discharge
The precision that filter disc filters in catalyst operating process, leakage is reduced, and substantially increase the use intensity and life-span of filter disc.
The technical solution adopted in the utility model is：
A kind of filter disc for separating paste state bed reactor dead catalyst, including the more sub- coaxial settings of filter disc, described son filter
Disk includes filter disc and disk hoop, and described disk hoop is coated on the outward flange of filter disc, also includes supporting plate and a pair of ring flanges, described
Supporting plate among be provided with flange hole, supporting plate is arranged on the centre of filter disc, and supporting plate size is identical with filter disc size, described
Supporting plate upper surface and lower surface on be uniform-distribution with multiple support columns, described support column one end and supporting plate vertical connection
Set, the other end contacts setting with filter disc inner body wall；Multiple screws are evenly arranged with described disk hoop, for using screw
Fastened；A pair of described ring flanges are arranged on filter disc center, and the first groove of circle is provided with flange end face
With the second groove, the first described groove and the second groove are disposed proximate to, filter screen are sealed for placing sealing strip.
Multiple screws are respectively arranged with described the first groove and the second groove, for fixing seal bar, filter disc to method
Lan Shang.
The filter opening of described filter disc is 3 μm.
The utility model is improved in the filter disc of existing separation paste state bed reactor dead catalyst, first in filter disc
Outside increases anchor ear, so that filter disc still can guarantee that intensity in the case where high-speed rotation works, filter screen is not indeformable damaged；
Secondly multiple circular ring-type seal grooves are increased on mounting flange end face, so that sealing is more stable；Finally in filter disc filter screen
By-level sets strengthening version and support column so that will not be by gravitational thrusts such as filter residues during the use of filter screen when produce shape
The phenomenon for becoming to come off.So to solve former filter disc filtering accuracy low for the utility model, easily leakage, and anchor ear damage
Bad the problems such as.
Brief description of the drawings
Fig. 1 is the structural representation of sub- filter disc described in the utility model；
Fig. 2 is the structural representation of flange described in the utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model includes the He of filter disc 4 by the more sub- coaxial settings of filter disc, described sub- filter disc
Disk hoop 2, described disk hoop 2 are coated on the outward flange of filter disc 1, also include supporting plate 5 and a pair of ring flanges 1, described support
Flange hole is provided among plate 5, supporting plate 5 is arranged on the centre of filter disc 4, and the size of supporting plate 5 is identical with the size of filter disc 4, described
The upper surface of supporting plate 5 and lower surface on be uniform-distribution with multiple support columns 6, described one end of support column 6 is vertical with supporting plate 5
Connection is set, and the other end contacts setting with the inner body wall of filter disc 4；Multiple screws are evenly arranged with described disk hoop 2, for making
Fastened with screw 3；Described a pair of ring flanges 1 are arranged on filter disc center, and circle is provided with flange end face
First groove 7 and the second groove 8, the first described groove 7 and the second groove 8 are disposed proximate to, for placing sealing strip to filter screen
Sealed.
Described supporting plate 5 is by surveying and drawing and testing, determine that filter disc strengthens plate thickness, form, install and add in filter disc
Strong plate, the intensity of filter disc is significantly increased, it is not deformed in use.
Multiple screws are provided with described the first groove 7 and the second groove 8, flange is arrived for fixing seal bar, filter disc 4
Upper 1.By to being surveyed and drawn at filter disc center, determining flange specification and type of attachment and seal groove positioning, passing through screw
