Description

Flexible joint assembly, screw conveyor and garbage transfer system

Technical Field

The application belongs to the technical field of connecting devices, and particularly relates to a flexible joint assembly, a screw conveyor and a garbage transfer system.

Background

The screw conveyor is widely applied to the garbage disposal industry due to the structural characteristics of full sealing and no material returning. In the refuse treatment production line, the materials can be transferred to downstream receiving equipment by a screw conveyor only through a closed rigid feeding hopper and a closed rigid discharging hopper. In order to reduce the influence of equipment position deviation on the connection of the rigid feeding hopper and the rigid discharging hopper, the conventional screw conveyor can use a flexible pipeline as an intermediate connecting piece between the feeding hopper and the discharging hopper, for example, a corrugated pipe made of an elastic material is selected, and the flexible connection between the discharging hopper of the screw conveyor and the feeding hopper of the downstream receiving equipment is realized. However, materials in the production line often contain hard materials such as gravel, glass, metal and the like, and the materials are easy to damage the flexible pipeline, so that dirt leakage occurs.

Detailed Description

The following describes specific embodiments of the present application in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the application, are not intended to limit the application.

The application will be described in detail below with reference to the drawings in connection with exemplary embodiments.

As shown in fig. 1-4, a first exemplary embodiment of the present application provides a flexible joint assembly for a screw conveyor, the flexible joint assembly 10 including a tapered conduit 101 and a flexible gland 102.

Wherein the conical conduit 101 comprises a conduit feed port for aligning with a conveyor feed port of the screw conveyor 20, and a conduit discharge port narrowed relative to the conduit feed port, for example, referring to fig. 4, for aligning with or extending into a receiving device feed port of the downstream receiving device 30 (not shown in the drawings); for another example, the conduit feed port is configured to be in alignment with the discharge port of the upstream discharge device, and the conduit discharge port is configured to be in alignment with the conveyor feed port of the screw conveyor 20. The flexible sealing sleeve 102 is sleeved outside the conical guide pipe 101, the upstream sleeve opening of the flexible sealing sleeve 102 is sleeved outside the guide pipe feed inlet, and the downstream sleeve opening is sleeved outside the guide pipe discharge outlet.

Referring specifically to fig. 3, the upstream sleeve opening of the flexible sealing sleeve 102 is slightly larger than the conduit feed opening of the tapered conduit 101, and the inner wall surface of the upstream sleeve opening is attached to the outer wall of the conduit feed opening to form a sealing state, that is, the upstream sleeve opening and the conduit feed opening are relatively fixed. Thus, when flexible joint assembly 10 is mounted on screw conveyor 20, although the upstream cuff of flexible gland 102 is aligned with and connected to the conveyor discharge port, the upstream cuff is in non-communication with the conveyor discharge port under the obstruction of tapered conduit 101, such that material output by screw conveyor 20 to flexible joint assembly 10 is transported solely through tapered conduit 101 without contacting flexible gland 102.

It can be seen that, the flexible joint assembly 10 of the present exemplary embodiment, by disposing the tapered conduit 101 in the flexible sealing sleeve 102, directly conveying the material by using the tapered conduit 101, is equivalent to isolating the material from the flexible sealing sleeve 102, so that the flexible sealing sleeve 102 is prevented from being damaged by the hard material, thereby effectively protecting the flexible sealing sleeve 102, prolonging the service life of the flexible sealing sleeve 102, and greatly reducing the risk of leakage of the material, so as to avoid environmental pollution. Simultaneously, the conical guide pipe 101 is gradually narrowed along the material conveying direction, so that the materials are more concentrated at the guide pipe discharge port, and the guide pipe discharge port and the material receiving equipment feed inlet can be effectively prevented from interfering with each other. In addition, it is also envisioned that, in the case of a dislocation of the conveyor discharge port and the receiving device feed port, the deformable characteristic of the flexible sealing sleeve 102 is utilized to enable the flexible sealing sleeve 102 to flexibly change the direction to adjust the docking direction, so as to reduce the difficulty of docking the screw conveyor 20 to the downstream receiving device 30.

In the present exemplary embodiment, the flexible sealing sleeve 102 may be made of flexible materials such as rubber, rubberized canvas, and the like, which is not limited in this embodiment.

It can be appreciated that, since the material can be conveyed by the tapered conduit 101, the screw conveyor 20 does not need to be shut down during the process of replacing the flexible sealing sleeve 102, in other words, the flexible sealing sleeve 102 can be disassembled and assembled during the process of conveying the material, thereby maintaining the normal production rhythm and improving the working efficiency.

Further, in order to enhance the wear resistance of the tapered conduit 101, the tapered conduit 101 is formed as a wear resistant conduit made of a material such as metal, ceramic, fiber, or the like. Therefore, the abrasion-resistant guide pipe is utilized to resist the impact of hard materials, so that the protection effect of the conical guide pipe 101 on the flexible sealing sleeve 102 can be improved, the flexible sealing sleeve 102 is prevented from being damaged, and the service life is effectively prolonged.

In one embodiment, the flexible joint assembly 10 includes compression structure for compressing the flexible boot seal 102. Specifically, referring to fig. 1 and 3, the edges of the upstream and downstream cuffs are turned outwards, and the compression structure includes a first ring plate 103 and a second ring plate 104, where the first ring plate 103 is crimped to the edge of the upstream cuff, and the second ring plate 104 is crimped to the edge of the downstream cuff, so that the tightness of the upstream and downstream cuffs can be ensured, and sewage or odor is prevented from escaping the flexible joint assembly 10.

Preferably, the size of the inner ring of the first ring plate 103 is consistent with the size of the discharge hole of the conveyor, and the size of the inner ring of the second ring plate 104 is consistent with the size of the feed hole of the receiving device. In actual use, referring to fig. 4, the peripheral edge of the conveyor discharge port is provided with a conveyor flange portion, the peripheral edge of the receiving device feed port is provided with a receiving device flange portion, and accordingly, the first ring plate 103 is formed as a first flange that can be disposed in alignment with the conveyor flange portion, and the second ring plate 104 is formed as a second flange that can be disposed in alignment with the receiving device flange portion.

Further, the pressing structure further includes a first penetrating member 105 and a second penetrating member 106, such as a bolt assembly, where the first penetrating member 105 is configured to detachably penetrate the first ring plate 103 and the conveyor flange portion when the flexible joint assembly 10 is connected to the screw conveyor 20 and the downstream receiving device 30, so that the flexible joint assembly 10 and the screw conveyor 20 can be connected, and the second penetrating member 106 is configured to detachably penetrate the second ring plate 104 and the receiving device flange portion, so that the flexible joint assembly 10 and the downstream receiving device 30 can be connected. It can be seen that, by providing the first penetrating piece 105 and the second penetrating piece 106, on one hand, the first ring plate 103 and the second ring plate 104 can be ensured to respectively compress the upstream sleeve opening and the downstream sleeve opening, so as to ensure the tightness of the flexible joint assembly 10, and on the other hand, the quick assembly and disassembly of the flexible joint assembly 10 can be realized by utilizing the detachable characteristics of the first penetrating piece 105 and the second penetrating piece 106, so that the operation of personnel is facilitated.

In the process of butting the screw conveyor 20 provided with the flexible joint assembly 10 against the downstream receiving device 30, the downstream sleeve opening of the flexible sealing sleeve 102 can swing relative to the guide pipe discharge opening of the conical guide pipe 101, so that the downstream sleeve opening can be adjusted to be aligned with the device feed opening, in the process, if the swing amplitude of the downstream sleeve opening is too large, the downstream sleeve opening is easy to collide with the guide pipe discharge opening, and materials in conveying can fall to the inner wall surface of the downstream section of the flexible sealing sleeve 102, so that the flexible sealing sleeve 102 has abrasion risk. In addition, after the flexible joint assembly 10 is assembled, a certain deflection swing angle (as shown in fig. 4) of the tapered conduit 101 may be allowed according to the actual placement situation of the equipment, but it should be satisfied that the conduit outlet of the tapered conduit 101 does not touch the equipment inlet of the downstream receiving equipment 30.

Therefore, referring to fig. 3 and 4, the discharge end of the tapered conduit 101 is suspended, and the discharge opening of the conduit is narrower than the inner ring of the ring plate of the second ring plate 104, so that the distance between the discharge end of the tapered conduit 101 and the second ring plate 104 is increased, the large swing adjustment of the flexible sealing sleeve 102 is facilitated, the tapered conduit 101 is suitable for connection between the screw conveyor 20 with large position deviation and the downstream receiving device 30, the requirement of large deflection of the tapered conduit 101 can be met, and the risk that the discharge opening of the conduit of the tapered conduit 101 touches the downstream receiving device 30 is reduced.

Of course, the tapered conduit 101 can be suspended above the second annular plate 104 or can extend through the second annular plate 104 into the downstream receiving apparatus 30 for placement, depending on the actual use requirements.

Further, the length of the sealing sleeve of the flexible sealing sleeve 102 is larger than the length of the guide tube of the tapered guide tube 101, so that the flexible sealing sleeve 102 has a larger swing adjusting space, the flexible sealing sleeve 102 and the tapered guide tube 101 are prevented from interfering with each other, meanwhile, the requirement of long-distance connection between the screw conveyor 20 and the downstream receiving device 30 can be met, and the tightness of long-distance conveying operation is ensured.

In addition, in the case where the seal sleeve length of the flexible seal sleeve 102 is set to be greater than the conduit length of the tapered conduit 101, the conduit discharge port and the receiving apparatus feed port that are originally aligned are allowed to horizontally shift and twist, and the maximum shift distance and twist angle are preferably such that the conduit discharge port does not interfere with the receiving apparatus feed port. On the other hand, the device can also adapt to the condition that the first annular plate 103 and the second annular plate 104 which are originally arranged in parallel mutually generate angle deflection, and the maximum deflection angle is suitable for ensuring that the discharge port of the guide pipe does not interfere with the feed port of the receiving equipment.

In order to further improve the flexibility of the flexible sealing sleeve 102 and ensure the effective connection between the screw conveyor 20 and the downstream receiving device 30, the flexible sealing sleeve 102 is formed as a telescopic sealing sleeve, such as a bellows as shown in fig. 1, and the connection requirements of the screw conveyor 20 and the downstream receiving device 30 under different distances can be met by adjusting the length of the telescopic sealing sleeve.

Of course, the length of the telescopic sealing sleeve of the present embodiment can be adjusted to be greater than the length of the tapered catheter 101 in the extended state, so that the adjustment requirement of wide-range swing can be met. In addition, the telescopic sealing sleeve can be entirely shortened to be shorter than the tapered catheter 101 in the contracted state.

In addition, to achieve removable installation of the tapered conduit 101, the tapered conduit 101 includes a conduit flange portion 1011 that is externally sleeved to the conduit feed inlet, and the flexible joint assembly 10 includes a fastening harness that can be used to harness the conduit flange portion 1011 and the screw conveyor 20. Thus, the pipe flange 1011 and the screw conveyor 20 are connected by fastening the connecting member, so that the tapered pipe 101 can be detachably attached, and the convenience of attachment and detachment can be enhanced.

Preferably, the conduit flange 1011 is identical in size to the first ring plate 103 and the conveyor flange, and in particular, referring to fig. 3, in the case of the above-mentioned three-alignment connection, the upstream pocket can be clamped by the conduit flange 1011 and the first ring plate 103, at this time, the first penetrating member 105 may be used as the fastening penetrating member, and the first ring plate 103, the upstream pocket, the conduit flange 1011 and the conveyor flange may be sequentially penetrated by the first penetrating member 105, so that the connection of the flexible joint assembly 10 and the screw conveyor 20 may be completed.

It should be noted that the flexible joint assembly 10 of the present application is not limited to the connection between the screw conveyor 20 and the downstream receiving device, but may be used for the connection between the screw conveyor 20 and the upstream receiving device, and the specific docking method refers to the above-mentioned method of docking the screw conveyor 20 and the downstream receiving device by using the flexible joint assembly 10. The flexible joint assembly 10 is utilized to connect upstream discharging equipment with the screw conveyor 20, so that the butt joint difficulty of the upstream discharging equipment and the screw conveyor 20 can be reduced, and the effective connection of the upstream discharging equipment and the screw conveyor 20 under the condition of position deviation can be met.

A third exemplary embodiment of the present application provides a refuse transfer system including an auger 20 mounted with the flexible joint assembly 10 described above. Referring to fig. 4, for example, the refuse transfer system further includes a downstream receiving device 30 downstream of the screw conveyor, the screw conveyor 20 and the downstream receiving device 30 being connected by a flexible joint assembly 10. In addition, the refuse transfer system includes an upstream discharge device 30 (not shown) located upstream of the screw conveyor, and the upstream receiving device may also be connected to the screw conveyor 20 by a flexible joint assembly 10. Needless to say, the refuse transfer system has all the technical effects brought about by the flexible joint assembly 10 described above, and therefore will not be described in detail here.
