Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the filter tube installation structure in this embodiment can be used in a common filtering environment, and can also be used in a harsh environment with a small installation space and strong vibration, such as a train. In the present embodiment, the filter pipe mounting structure will be described by taking an application of the filter pipe mounting structure to a train sewage tank as an example.
The high-speed rail and the dirt boxes carried by the motor train are hung at the bottom of the carriage. All there is equipment arrangement around the train advancing direction, and the space is very little between the equipment, is unfavorable for overhauing. Therefore, from the viewpoint of easy maintenance, the filter tube 14 should be arranged in the dirt box perpendicular to the direction in which the train travels. So that it can be taken out from any side of the carriage at a later date for maintenance or cleaning. The length of the sewage tank perpendicular to the running direction of the train is at least more than two meters, so the length of the single filter tube assembly is at least more than two meters. Two opposite box walls 15 of the sewage box are correspondingly provided with mounting holes, and the filter tube mounting structure is erected and connected in the mounting holes along the width direction of the train.
The filter tube mounting structure comprises two fixing sleeves 4, and the two fixing sleeves 4 are welded in mounting holes of a box wall 15. A filter tube component is connected between the two fixed tubes, and two ends of the filter tube component are respectively detachably connected in the fixed sleeve 4.
And two outer end parts of the filter tube assembly are connected with a mouthpiece 1, wherein one mouthpiece 1 is used for connecting a sewage output tube on a train, and the other mouthpiece 1 is used for connecting a sewage collecting device.
The filter tube assembly in this embodiment comprises a filter tube 14 and a filter tube connector 13 connected to the outer end of the filter tube 14, wherein the filter tube 14 is welded to the filter tube connector 13 in this embodiment. The inner end of each interface tube 1 is connected with an interface connecting piece 12, the interface tube 1 is connected with the interface connecting piece 12 in a welding way, and the interface connecting piece 12 is connected with the filter tube connecting piece 13 in a threaded way. In this way, a detachable connection between the filter cartridge 14 and the mouthpiece 1 can be achieved via the mouthpiece connection 12 and the filter cartridge connection 13. The mouthpiece connector 12 and the filter tube connector 13 in this embodiment have through holes therein to ensure communication between the mouthpiece 1 and the filter tube 14. The specific connection mode is as follows: the mouthpiece 1 is attached within the inner bore of the filter tube connector 13 such that the outer end face of the mouthpiece 12 forms a step face at the junction of the mouthpiece 1 and the mouthpiece 12. The filter tube connector 13 is connected in the inner bore of the filter tube 14 and the mouthpiece connector 12 is connected in the inner bore of the filter tube connector 13.
When the device is installed, the filter tube 14 and the mouthpiece 1 are connected through the filter tube connector 13 and the mouthpiece connector 12, and are inserted into the fixing sleeve 4 from one end of the mouthpiece 1.
The filter tube assembly needs to be fixed in inner holes of the fixing sleeves 4 at two ends of the sewage tank, and the coaxiality deviation of the two-meter long filter tube assembly can only be controlled within 5 millimeters at most according to the conventional processing level. The inner hole coaxiality deviation of the fixed sleeve 4 which is connected with the sewage tank and is two meters away can only be controlled within 5 millimeters at most. So, single filter tube subassembly penetrates the hole of the fixed sleeving 4 at the both ends of filth case, and filter tube subassembly and fixed sleeving 4's internal face are at radial reserve clearance size, and on average need reach 5 millimeters, and the biggest local clearance will reach 10 millimeters. Since the filter tube assembly needs to be sealed with the inner wall surface of the fixed sleeve 4, the liquid in the sewage tank is prevented from seeping out. Therefore, in the design of the sealing structure, how to reserve the installation gap margin needs to be considered, and the gap needs to be reasonably filled for liquid sealing.
In the present embodiment, a balance ring 11 is disposed between the fixed sleeve 4 and the filter tube connector 13, and the inner diameter of the balance ring 11 is gradually reduced from the outside to the inside in the axial direction, that is, the inner wall of the balance ring 11 has a taper. Meanwhile, a sealing gasket 10 and a sealing ring 9 are respectively arranged between the fixed sleeve 4 and the interface connecting piece 12. A pressure pad 7 is provided between the mouthpiece 1 and the retaining sleeve 4. In this embodiment, the cross section of the pressure pad 7 is L-shaped, the radial portion of the pressure pad 7 is fixedly connected to the outer end face of the interface connection through a screw 8, and the axial portion of the pressure pad 7 axially extends into the gap between the filter tube connector 13 and the fixing sleeve 4 and is pressed on the balance ring 11.
During installation, the balance ring 11, the sealing ring 9, the sealing gasket 10 and the pressure pad 7 are sequentially placed in the groove, and the balance ring 11, the sealing gasket 10 and the sealing ring 9 can be tightly pressed after the pressure pad 7 is fixed. The balance ring 11 in the embodiment is made of metal materials, and because the inner wall of the balance ring 11 is provided with a cone angle, the centers of the fixed sleeve 4 and the filter tube assembly can be automatically centered, and the effect of automatically adjusting the installation centers of the fixed sleeve 4 and the filter tube assembly is achieved. So that the filter tube assembly can not cause uneven installation clearance of the filter tubes 14 due to poor control of the coaxiality deviation of the processing and manufacturing of the fixed sleeve 4 during installation. And the first line sealing is realized by the inclined conical surface of the balance ring 11.
The sealing ring 9 is made of soft sealing materials such as rubber and the like, so that the soft sealing effect is achieved, the sealing gasket 10 achieves the excessive connection effect of soft and hard sealing, and after the pressing pad 7 is fixed, the sealing ring 9 and the sealing gasket 10 transmit pressing force, so that the balance ring 11 is uniformly stressed, and is stably installed and sealed. The pressure pad 7 can also enable the sealing ring 9 to deform uniformly, and the gaps between the two ends of the filter tube assembly and the fixed sleeve 4 are filled, so that the second sealing is realized. The pressure pad 7 provides a pressing force for the two seals. Reliable sealing is achieved.
The sewage tank collects the fecal sewage. As the train runs at a non-uniform speed, sewage in the sewage tank vibrates, and one wave and another wave of surge are caused to impact the wall and the internal structural parts of the sewage tank. Conventional dirt boxes are often provided with a swash plate to mitigate such surge impacts. However, the solid-liquid separation is used in the sewage tank to extend the sewage discharge period of the sewage tank, so that the solid sewage in the sewage tank is concentrated and the fluidity thereof is poor. If set up the swash plate, because the mobility is poor, be difficult to by the suction away by concentrated solid filth, can cause in the incasement part to pile up, even wash the filth case in the follow-up operation of unloading, also can block and be difficult to wash totally because of the swash plate. So long-term accumulation, the dirty case can reduce effectively and receive dirty space because of remaining solid filth is piled up in a large number. Therefore, it is necessary to eliminate the swash plate in the waste tank to facilitate the cleaning of the solid waste in the waste tank. In this way, the filter pipes 14 for solid-liquid separation need to bear the surge generated by train operation, and how to transmit and disperse the vibration impact stress borne by the filter pipes 14 needs to be considered, so that the box structure is not damaged.
In this embodiment, the middle portion of the mouthpiece 1 is an inclined tube section with a taper on the outer wall, an inner and outer taper sleeve 6 is sleeved outside the inclined tube section, and an expansion connecting sleeve 5 is arranged between the inner and outer taper sleeve 6 and the fixing sleeve 4. The accurate positioning of the installation positions of the inner and outer taper flower sleeves 6 and the expansion connecting sleeve 5 can be realized through the matching of the inclined pipe section on the interface pipe 1 and the inner and outer taper flower sleeves 6. Thus, the inner and outer taper sleeve 6, the expansion connecting sleeve 5 and the fixed sleeve 4 form the whole fixed damping device. The vibration impact stress born by the filter tube 14 in the sewage box is transmitted to the inner and outer cone sleeves through the filter tube connecting piece 13, the interface connecting piece 12 and the interface tube 1 in sequence by the damping device, and then transmitted to the expansion connecting sleeve through the inner and outer cone sleeves, and the whole formed by the vibration impact stress transmitting component is connected with the inner wall of the fixed sleeve 4 in an expansion way through the expansion connecting sleeve, so that the filter tube 14 is ensured to transmit and disperse the received stress to the fixed sleeve 4 in time when receiving impact vibration without damaging the box body structure. The pipe wall thickness transition that fixed sleeve 4 reasonable in design can replace the filth case wall, effectively bears the vibration impact stress who transmits and come, guarantees the filth case under the prerequisite that does not increase wall thickness, and structural strength is safe.
The outer port upper cover of fixed sleeve 4 is equipped with shield 2, and shield 2 cover is established outside mouthpiece 1. The middle part of the inner wall of the dustproof cover 2 is provided with a groove, and a dustproof pad 3 which can be sleeved outside the mouthpiece 1 is arranged in the groove. The dust cap 2 and the dust pad 3 can prevent contaminants in the environment from entering the mouthpiece 1 and the filter tube 14, thereby avoiding the contaminants from corroding and affecting the service life of the mouthpiece and the filter tube.
In addition, the filter tube mounting structure can be conveniently mounted and dismounted, the assembly can be easily disassembled by using a conventional tool during subsequent maintenance and dismounting, and the replaceability is strong. According to this scheme structural design, need not to carry out special training to operating personnel, above-mentioned subassembly dismouting can realize accomplishing through conventional allen key.
