Description
Technical field
The utility model relates to filter for installation, specifically, is a kind of filter head housings body structure.
Background technology
Filter is the very wide device of a kind of industrial applicability, and generally speaking, the filter of cup-like structure is made up of by being threaded the end socket that is positioned at case top and a cup-shaped cylindrical shell that is mounted with filter element.When commercial Application, need several filter series connection to use usually, make can reach specific quality requirement through the gas after the filter filtration.
Under this series connection occupation mode, common way is that the through hole that several filter head housings body and function bolts pass the shell cover both sides is linked together, or adopts and to have the studs that is complementary with the import and export thread size of filter end socket and carry out short circuit and be connected.These two kinds of methods have installs relative complex, easily produces the unnecessary gas pressure drop and the shortcoming of leakage.Therefore, need provide a kind of filter housings that can overcome above-mentioned shortcoming.
The utility model content
Technical problem to be solved in the utility model provides a kind of new filter housings, the installation complexity when using to reduce the filter series connection, and can prevent the generation of gas pressure drop and leakage.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: a kind of filter housings, comprise interconnective end socket and cylindrical shell, offer at least one gas channel on the described end socket, be provided with filter core in the described cylindrical shell, wherein, the outlet of described gas channel is positioned on the outer face of end socket, and the position of corresponding gas channel both sides offers wedge-shaped impression longitudinally respectively on the housing, constitutes a sharp angle between the bottom surface of described groove and the described outer face.
Further, the cross section of described wedge-shaped impression is "T"-shaped, and the top of described wedge-shaped impression is communicated to a semi-circular groove body.
Further, the position in corresponding gas channel exit also is provided with an annular groove on the described end socket, to hold an O-ring seal.
When two identical described housings splice mutually, the space that wedge-shaped impression surrounded of adopting one " worker " font chock to insert two correspondences.
Further, the central authorities of described chock offer screw, screw in this screw via the described semicircle cell body on the housing by a bolt to interconnect two housings fixing.
Further, offer two gas channels on the described end socket.
Filter housings of the present utility model is owing to adopted the design of wedge-shaped impression, make when two filters are connected shoulder to shoulder, only need chock is inserted in the wedge-shaped impression of two adjacent faces, two filters are closely linked together, simple in structure, the installation complexity is low.In addition, when two filter splicings, corresponding gas channel is the state of axially aligning, thereby can prevent the generation of gas pressure drop and leakage, has improved the security of operation.

Fig. 2 is the cutaway view of II-II cross section among Fig. 1, has shown the state that two filters with this structure link together.
Fig. 3 is the phantom of III-III cross section among Fig. 2.
Fig. 4 is the supporting construction schematic diagram of the utility model filter housing.
The specific embodiment
Below with reference to accompanying drawing filter housings of the present utility model is described in further detail, is specially following embodiment:
As shown in Figure 1, the end socket 1 of cupped form of strainer is used for linking with the cup-shaped cylindrical shell that comprises filter element, the upper end of cup-shaped cylindrical shell be processed to end socket on the helicitic texture that matches of screw thread 2, and be threaded into the back and link together with end socket 1.The inside of filter housings is divided into inner room 4 with circular section and the mistress 5 who encircles the cross section by circular cylinder 3.Article one, gas channel 6 enters inner room 4 by the opening that is positioned on housing one side end face 7 via annular mistress 5, and another gas channel 8 is coaxial with gas channel 6, links to each other with through hole on the housing opposite side end face 9 by annular mistress 5.Housing also is provided with the through hole that is connected with inner room 4 and mistress 5, to be used for assembling differential manometer.These two holes are respectively by bolt 10 and 11 sealings, shell cover 1 top has the shallow slot of flanged pin 12, this shallow slot can seal by detachable end, in the time of the assembling differential pressure indicator, can conveniently remove the part of end cap, perhaps the upper end of end socket 1 also can transform the structure that can be connected with another cup-shaped cylindrical shell as.
Please be simultaneously with reference to Fig. 2, the both sides end face 7 of end socket 1 and 9 structural similarity, this paper only describes in detail at end face 9.As previously mentioned, gas channel 8 links to each other with end face 9, and the surface of connecting portion is processed to the coaxial annular groove 13 of gas channel 8 and can holds a sealing ring 14.Also offer two through hole 15a, 15b in the both sides of end face 9, lay respectively at the both sides of gas channel 8.These two through hole 15a, 15b are T shape cross section, and lozenges 16,17 in including, and as shown in Figure 3, lozenges 16 is positioned at the inboard of end face 9 in this, and form a sharp angle with end face 9.Each through hole 15a, 15b have and 8 vertical longitudinal axis of gas channel, and via openings bottom surface 18 is vertical respectively with end face 9 with longitudinal axis.Also offer the groove of the semi-circular section as 19 to the top of each through hole 15a or 15b from the upper surface of end socket 1.
Two housings as shown in Figure 1 can interconnect by using two chocks 20,21 shown in Figure 2.One is inserted through hole 15a and the through hole similar to through hole 15a 22 that is arranged in another housing, and another inserts through hole 15b and the through hole similar to through hole 15b 23 that is arranged in another housing.Can clearly be seen that from Fig. 1 each chock 20,21 all comprises a center caulking groove 24 and full thread through hole 25, is respectively the part 26,27 of chock on caulking groove 24 both sides, is respectively the tenon shape face 28,29 that contacts with the inner wedge surface of through hole in the middle of it.Such two housings can link to each other by the sealing rings 14 that embed in the groove 13, and make two gas channels 8 and 30 axially in line.Chock 20,21 inserts from the via bottoms in T type cross section, and nut 31,32 passes full thread through hole 25 to tighten.Reciprocation by chock 20,21 surfaces is moved together two shells to, and the end face between two filters is by sealing ring 14 sealings, thereby realizes between the gas channel 8 and 30 of two filter housings reliably, is tightly connected completely.If desired, filter housing can be installed on the support 40, passes the hole 42,43 on the support 40 respectively and is screwed into and locks from the bottom of T type cross section full thread through hole 25 with bolt 41.
Can see,, can not interfere gas flow by any way between two housings with the connection that chock forms.Below only describe preferred lozenges structure, in other embodiment of the present utility model, also can adopt any lozenges structure that makes adjacent two filter housings end faces reach the fastening effect of sealing.
Below with reference to Fig. 4 a kind of optional rack mounting structure is described.One filter housings 51 is made up of end socket shown in Figure 11, cup-shaped type tube body 52 shown in Figure 4 and the end cap 53 that is installed on case top, adopts between cup-shaped cylindrical shell 52 and the end socket to be threaded.Have groove 54, the 55 interior inserting bolts 56,57 respectively of wedge surface, the through hole 58 that these two bolts 56,57 pass on the support 59 is connected with nut 61,62 respectively, thereby housing is fixed on the support 59.In order to reach better sealing, the exit of gas channel 64 also can be provided with packing ring 63.In addition, offer through hole 60 on the support 59, entire bracket 59 is fixed on the supporting surface together with housing by screw or bolt.
