Abstract
The utility model discloses a filter tube mounting structure of a gas filter device after a connection property between a sheath and a connector is enhanced. The filter tube mounting structure is characterized in that the upper end of a filter tube is mounted on a pore board through a self-aligning type connection piece; the self-aligning type connection piece comprises the sheath, the connector, a buffer gasket, a sealing gasket and a nut; the sheath covers the upper end of the filter tube to form an outer flange by increasing an outer diameter; the connector is located at the position of an upper end opening of the filter tube, and is adaptively connected with the sheath through an inner thread on the sheath and an outer thread on the connector; the upper end of the connector passes through the pore board, and then is connected with the nut; the buffer gasket is located on the fit face of the sheath and the outer flange; and the sealing gasket is located between the upper end face of the filter tube and the lower end face of the connector. Furthermore, a transverse limiting structure for rightly sheathing the outer surface after the sheath and the connector are in threaded connection is arranged on the connector. The transverse limiting structure can be used for enhancing the connection property of the sheath and the connector.
Description
Technical field
The utility model relates to gas-filtering device, is specifically related to the chimney filter mounting structure of gas-filtering device.
Background technology
In order to overcome in existing gas-filtering device because of the unsettled chimney filter lower problem that produces than macrobending stress in working order that causes in chimney filter lower end, the present inventor once provided corresponding solution in the patent documentation of CN201959676U.The emphasis of this solution is in the position near these chimney filters lower ends, one support to be set, have on this support and each chimney filter locating hole one to one, then will be connected on each chimney filter lower end locating shaft respectively with corresponding locating hole matched in clearance, thereby cross spacing is carried out in the chimney filter lower end, improve thus the force-bearing situation of chimney filter.in this solution also subsidiary providing realize the self-aligning connector that is connected between a kind of upper end that makes chimney filter and orifice plate, shown in document accompanying drawing 1, this self-aligning connector comprises: jacket, joint, buffering spacer, gasket seal and nut, described jacket embraces the chimney filter upper end and increases and the outward flange that forms through external diameter, described joint the upper port place of chimney filter and with jacket between by the internal thread on jacket with the external screw thread on joint is adaptive connects, the upper end of joint connects with described nut after passing orifice plate again, described buffering spacer is positioned on the mating surface of jacket and outward flange, described gasket seal is between the lower surface of the upper surface of chimney filter and joint.
After this, it is spacing that the inventor attempts again the lower end of cancelling chimney filter, but new departure of chimney filter still is installed with above-mentioned self-aligning connector.The inventor finds, after cancellation is spacing to the lower end of chimney filter, the vibration severe degree of chimney filter under in working order obviously increases, if permanent in the past the thread connection between jacket and joint easily occur looseningly, the sealing property between chimney filter and joint may be affected.
The utility model content
The utility model aims to provide a kind of chimney filter mounting structure of the gas-filtering device after the coupling performance simulating between above-mentioned jacket and joint is strengthened.
chimney filter mounting structure of the present utility model is: the upper end of described chimney filter is arranged on orifice plate by the self-aligning connector, described self-aligning connector comprises jacket, joint, buffering spacer, gasket seal and nut, described jacket embraces the chimney filter upper end and increases and the outward flange that forms through external diameter, described joint the upper port place of chimney filter and with jacket between by the internal thread on jacket with the external screw thread on joint is adaptive connects, the upper end of joint connects with described nut after passing orifice plate again, described buffering spacer is positioned on the mating surface of jacket and outward flange, described gasket seal is between the lower surface of the upper surface of chimney filter and joint, in addition, described joint is provided with and connects the cross spacing structure of just blocking the jacket outer surface after putting in place when jacket with joint screw thread.
Concretely, the periphery wall that described cross spacing structure comprises the flange that is positioned on the joint outer wall and extends axially out downwards from the flange outer sides limit, the inner surface of described periphery wall and the outer surface of jacket are suitable.
The cross spacing structure has been shared the chimney filter oscillation crosswise and has been applied to load on jacket, coupling performance simulating between jacket and joint is strengthened, prevent that effectively the thread connection between jacket and joint from occuring to become flexible, the problem that the sealing property between chimney filter and joint descends.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Description of drawings
Fig. 1 is the application's chimney filter mounting structure schematic diagram.
The specific embodiment
as shown in Figure 1, the upper end of chimney filter 7 is arranged on orifice plate 2 by the self-aligning connector, the lower end of chimney filter 7 is unsettled, described self-aligning connector comprises jacket 5, joint 3, buffering spacer 6, gasket seal 4 and nut 1, described jacket 5 embraces chimney filter 7 upper ends and increases and the outward flange 701 that forms through external diameter, described joint 3 the upper port place of chimney filter 7 and with jacket 5 between by adaptive connection of external screw thread on the internal thread on jacket 5 and joint 3, the upper end of joint 3 connects with described nut 1 after passing orifice plate 2 again, described buffering spacer 6 is positioned on the mating surface of jacket 5 and outward flange 701, described gasket seal 4 is between the lower surface of the upper surface of chimney filter 7 and joint 3, described joint 3 is provided with the cross spacing structure of just blocking jacket 5 outer surfaces after jacket 5 and joint 3 thread connection put in place, the periphery wall 302 that this cross spacing structure comprises the flange 301 that is positioned on joint 3 outer walls and extends axially out downwards on flange 301 outer side edges, the outer surface of the inner surface of described periphery wall 302 and jacket 5 is suitable.As can see from Figure 1, periphery wall 302 is enclosed within on the outer surface of jacket 5 upper ends, a load part that is applied on jacket 5 when therefore chimney filter 7 vibrates is absorbed by the part of carrying out thread connection with jacket 5 on joint 3, another part load is absorbed by periphery wall 302, has prevented that the thread connection between jacket 5 and joint 3 from loosening hidden danger occuring.
