Description

The filter inner core unit of clamping filter bag

Technical field

The utility model relates to a kind of chemical filtration unit, is meant a kind of filter inner core unit of clamping filter bag especially.

Background technology

As shown in Figures 1 and 2, existing a kind of filter includes the filter bag 3 and that filter cylinder 2, that a body 1, is installed in this body 1 inside is installed in these filter cylinder 2 inside and produces the panel 4 of location for this filter bag 3.These body 1 one inner ring surfaces radially convex with a flange 101, this filter cylinder 2 has a stack shell 201, one-body molded the bulge loop 202 that is attached at these stack shell 201 tops, this stack shell 201 has the filter opening 203 that majority runs through, this bulge loop 202 is to only being positioned on this flange 101, with most screws 5 this bulge loop 202 is locked on this flange 101 again, and this bulge loop 202 has more most L type draw-in grooves 204 that are arranged with by an inner ring surface.The inner peripheral surface of this filter cylinder 2 has a big footpath section 206 and the shoulder 207 between these large and small footpath section 206,205 joining places that a path section 205, is located at these path section 205 tops.This filter bag 3 has the locating ring frame 302 that a filter screen 301 and is installed in these filter screen 301 openends, and this locating ring frame 302 is can be resisted against on this shoulder 207.The outer peripheral face of this panel 4 convexes with majority can be nested in teat 401 in these L type draw-in grooves 204, and rotation again after utilizing these teats 401 to be inserted in this L type draw-in groove 204, can make this panel 4 be combined on this filter cylinder 2, and this locating ring frame 302 is produced compacting.

Though, the teat 401 that utilizes this panel 4 is nested with these L type draw-in grooves 204, can make the locating ring frame 302 of this filter bag 3 produce the cramping positioning action, but, because these L type draw-in grooves 204 can't moulding in the lump (demoulding smoothly) when filter cylinder 2 ejection formations, but will remake the machining of secondary after this filter cylinder 2 is made, and the processing of these L type draw-in grooves 204 comparatively bothers, manufacturing cost is higher.

The utility model content

The utility model provides a kind of filter inner core unit of clamping filter bag at the above-mentioned defective of prior art.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The filter inner core unit of the utility model clamping filter bag, this inner core unit is that a body interior is installed, and be positioned at inside for the filter bag installation, this filter bag has the panel that a filter screen and is installed in this filter screen openend, and this inner core unit comprises a filter cylinder and a screw lock and is positioned at keeper on this filter cylinder.This filter cylinder has one can form the perisporium of a room and the filter opening that majority runs through this perisporium, the inner peripheral surface of this perisporium has a path section, and is located at the big footpath section and of this path section top and is engaged between this large and small footpath section and for the shoulder of this panel against the location, this big footpath section has an internal thread.This keeper is to make hollow out ring frame shape, and has a lateral surface, medial surface and at least one rib that be attached at this medial surface between opposite with this lateral surface, but this lateral surface has the external screw thread of screw lock screw thread within this filter cylinder.

As can be seen from the above technical solutions, the utility model utilize this keeper with the external screw thread screw lock on the internal thread of this filter cylinder, be to make filter bag by this keeper clipping location, polarization is good, and whole manufacturing, assembly are more or less freely.

The specific embodiment

Below in conjunction with the specific embodiment the utility model is described in further detail.

As shown in Figures 3 and 4, the filter inner core unit preferred embodiment of the utility model clamping filter bag, this inner core unit 100 is that a body 200 inside are installed, and is positioned at inside for a filter bag 300 installations.This body 200 is to be hollow tube-shape, and inner ring surface radially convexes with a flange 210.This filter bag 300 has the panel 320 that a filter screen 310 and is installed in these filter screen 310 openends.This inner core unit 100 comprises a filter cylinder 10, a screw lock is positioned at keeper 20 and the leakproof assembly 30 of a clipping between this filter cylinder 10 and this panel 320 on this filter cylinder 10.

This filter cylinder 10 is with plastic material and utilizes injection molding method to make hollow tube-shape, and has the bulge loop 12 that a stack shell 11 and is attached at these stack shell 11 tops, and this stack shell 11 and bulge loop 12 are common to be constituted perisporiums 13 and define a room 14.This stack shell 11 has the filter opening 111 that majority runs through this perisporium 13, the inner peripheral surface of this perisporium 13 has that a path section 131, is located at that the big footpath section 132 and of these path section 131 tops is engaged between this large and small footpath section 132,131 and for the shoulder 133 of this panel 320 against the location, should big footpath section 131 have an internal thread 134, this shoulder 133 has a circular groove 135.

This keeper 20 is to make hollow out ring frame shape, and have a lateral surface 21, a medial surface 22 and opposite with this lateral surface 21 is attached at the rib 23 between this medial surface 22.But this lateral surface 21 has the external screw thread 211 of screw lock screw thread 134 within this filter cylinder 10.

This leakproof assembly 30 is to be embedded in this circular groove 135, and clipping is between this shoulder 133 and this keeper 20 bottom surfaces.

Fig. 3 and shown in Figure 5 for another example, after assembly is finished, the bulge loop 12 of this filter cylinder 10 is to be resisted against on the flange 210 of this

body

200, and 320 of the panels of this filter bag 300 are resisted against on this shoulder 133, when this keeper 20 utilizes on the internal thread 134 of external screw thread 211 screw locks at this filter cylinder 10, and when this panel 320 produced compacting, these filter bag 300 integral body can obtain preferable polarization, and behind these filter cylinder 10 ejection formations, the processing of this internal thread 134 is quite easy, and whole manufacturing cost is lower.

Therefore, inner core of the present utility model unit 100 is firm clamping filter bag 300 not only, and compared to existing structure, whole manufacturing, processing, assembly are all quite easy.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
