Abstract

The utility model relates to a seal fastening device for a lid body of a filter, which comprises at least two fastening hoops, wherein the upper and the lower inner walls of the hoops are conical surfaces; the hoops are connected through hinges; the end heads of the head and rear fastening hoops are respectively connected with a nut supporting seat; nuts respectively with a positive and a reverse threads holes are arranged in the nut supporting seat; the nuts are connected through screw rods with positive and reverse thread sections; the screw rods are connected with a hand wheel. When the lid cover of a filter is opened, the hand wheel on the screw rod is only screwed; the hoops are released; the utility model has the advantages of simple structure, convenient and rapid operation, and high work efficiency. When the hoops are tightly screwed, the good fastening effect between the lid body of a filter body and a cylindrical body can be ensured because the inner walls of the hoops are conical surfaces, and the lid body of a filter body and the cylindrical body are conical surfaces.

Description

The sealing fastening device of filter lid

(1) technical field: the utility model relates to filter, relates in particular to the accessories apparatus of filter-press.

(2) background technology: filter-press comprises cylindrical shell and lid, installs filter core in the cylindrical shell.Between lid and the cylindrical shell sealing ring is housed, and requires with fastener lid and cylindrical shell sealing is fastening.In the prior art both sealings fastening be to install many fastening bolts and nut thereof additional along lid and cylindrical shell periphery, its shortcoming is will open or when closing lid, the installation of bolt nut and dismantle time-consumingly, speed is very slow, inefficiency.

(3) summary of the invention: the purpose of this utility model is to provide the sealing fastening device of another kind of filter lid at above-mentioned shortcoming, and it is simple in structure, and is fastening effective, installs fastening or dismantles when fastening convenient to operation.

Technical solutions of the utility model are as follows:

It comprises left and right two lobe anchor ears, and the upper and lower internal face of two lobe anchor ears is the conical surface; One end of two lobe anchor ears connects by hinge, and the other end is attaching nut's supporting base respectively, and device has the nut of positive and negative screwed hole in the nut support seat, and described nut connects with the screw mandrel that has positive and negative thread segment, and screw mandrel connects handwheel.Described nut is cylindrical, and the one end is a T shape, and described nut support seat has arc groove, installs barrel nut in the described arc groove.

It is the lid of the next fastening filter of anchor ear of the conical surface that the utility model adopts by hinge connection and internal face, anchor ear is fastening with the screw mandrel and the nut that have positive and negative screw thread, when opening the filter lid, as long as the handwheel on the rotary screw, unclamping anchor ear gets final product, simple in structure, easy to operate, quick, high efficiency.When screwing anchor ear, because the anchor ear internal face is a taper surface, the flange of filter lid and the welding of cylindrical shell edge also is a taper surface, so can guarantee the fastening effect that filter lid and cylindrical shell are good.

(4) description of drawings:

Fig. 1 is the front view of the utility model embodiment, broken section among the figure;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the installation diagram of the utility model hinge, along the A-A direction broken section of Fig. 2.

Each figure ratio is not quite similar.

(5) specific embodiment:

See Fig. 2, the utility model comprises left lobe anchor ear 1 and right lobe anchor ear 5, and anchor ear 1 and an end of 5 connect by hinge, flap 2,4 respectively with

anchor ear

1 and 5 welding, 3 is hinge axis.The

anchor ear

1 and 5 the other end be welded

nut supporting base

8 and 11 respectively.See Fig. 1, Fig. 2, in the

nut support seat

8 and 11 respectively device have the

nut

9 and 12 of positive and negative screwed hole,

nut

9 and 12 usefulness have with the screw mandrel 7 of its corresponding positive and negative thread segment and are connected, screw mandrel 7 one ends are fastenedly connected handwheel 6 with screw.

See Fig. 1, Fig. 2,

nut

9 and 12 is cylindrical, the termination of one end is respectively T shape, have arc groove in the

nut support seat

8 and 11, install

cylindrical nut

9 and 12 in this arc groove respectively, nut 9 and 12 T shape termination are positioned at the upper surface of

nut support seat

8 and 11, and

nut

9 and 12 can not fallen down.See Fig. 1, Fig. 3,

anchor ear

1 and 5 last internal face and down internal face be the conical surface.

See Fig. 1,13 is the upper flange that is connected with filter lid 14 seal weldings among the figure, 15 is the hand lobe of opening cover, 18 is the lower flange that is connected with filter cylinder 17 seal weldings, 19 is sealing ring, and when anchor ear was held tightly, the male cone (strobilus masculinus) of upper flange 13 and lower flange 18 and the upper and lower internal face of anchor ear matched, anchor ear is supported on the support 16, and support 16 is welded on the wall of filter cylinder 17.See Fig. 3, flap 4 is welded to connect with anchor ear 5, and hinge 3 inserts in flap 4 and 2, and 20 is the limiting plate of hinge 3, and plate 20 is welded on the wall of cylindrical shell 17.

See Fig. 1, Fig. 2, because the fastening effect of the positive and negative screwed hole of the positive and negative thread segment of screw mandrel 7 and

nut

9,12, when a direction was shaken handwheel 6,

anchor ear lobe

1 and 5 was held tightly, and

flange

13 and 18 is fastening, and the lid 14 of filter is sealed fastening with cylindrical shell 17; Shake handwheel 6 in the other direction,

anchor ear

1 and 5 unclamps certain distance, can hold hand lobe 15 and upwardly open lid 14.

In embodiment illustrated in fig. 2, the utility model comprises left and right two lobe anchor ears, and this sealing that is suitable for the less filter lid of size is fastening.Sealing for large-scale filter lid is fastening, also can comprise the anchor ear that two lobes are above, for example comprise three lobe anchor ears, this moment first and second and second with the 3rd lobe anchor ear between be connected by hinge, the termination of the first and the 3rd lobe anchor ear is attaching nut's supporting base respectively, and other structures are identical with Fig. 2.
