The top of one end of the condenser shell 1 is provided with an access window 16, and the outer wall of the condenser shell 1 is weldedly connected with a packaging rib 2. Figures 1-4
[0031] The packaging rib 2 surrounds the access window 16. By slidingly connecting the cover 5 at the outer wall of the condenser shell 1 and supporting it with the packaging rib 2, the top of the access window 16 can be blocked. When the condenser effect is poor, the cover 5 can be moved at the top of the condenser shell 1 to expose the access window 16 in the field of view, so as to facilitate the confirmation of the external dirt of the pipeline 15 and the damage inside the condenser shell 1, and thus the corresponding maintenance work (simple cleaning or disassembly and cleaning maintenance) can be performed according to the actual situation.
[0032] As shown in FIG. 2, the two long edges of the cover 5 are weldedly connected with rib plates 6. The two rib plates 6 and the two long edges of the packaging rib 2 are both provided with a plurality of clamping assemblies. The inside of the two long edges of the packaging rib 2 is provided with a strip-shaped groove 14. The clamping assembly includes a support seat 9, the bottom of which is provided with a second threaded rod 11 on both sides, and the outside of the second threaded rod 11 is provided with a roller 13. The top center of the support seat 9 is welded with a first threaded rod 7, and the top of the first threaded rod 7 is threadedly connected with a first nut 8. Figures 1 to 3
[0033] The top of the support seat 9 passes through the inside of the strip-shaped groove 14 and the rib plate 6. After the first nut 8 is threadedly connected with the first threaded rod 7, the roller 13 is pressed on the surface at the bottom of the long edge of the packaging rib 2, so that the inner wall of the cover 5 is tightly attached to the outer wall of the condenser shell 1, and the sealing effect of the cover 5 at the access window 16 and the outer wall of the condenser shell 1 is ensured.
[0034] As shown in FIG. 3, the two long edges of the packaging rib 2 are provided with a plurality of trapezoidal blocks 17, and the trapezoidal blocks 17 are arranged in the strip-shaped groove 14.Figure 2 and Figure 3 As shown in the figure, the inner part of the two sides of the roller 13 is interference fitted with the bearing 12, the second threaded rod 11 passes through the inner part of the two bearings 12, and the second nut 10 is threadedly connected;
[0035] Wherein, by supporting one side of the second nut 10 in the inner side of the bearing 12 away from the support base 9, and supporting the end of the second threaded rod 11 connected with the support base 9 in the inner side of the bearing 12 close to the support base 9, when the rib plate 6 is slidingly connected at the top of the long side of the packaging rib part 2, the roller 13 can roll on the bottom surface of the long side of the packaging rib part 2.
[0036] In some examples, the cover 5 is weldedly connected with the rib ring 4 close to the outer wall of one end of the middle part of the condenser shell 1. By welding the two ends of the rib ring 4 with the top surface of the two rib plates 6 respectively, the rib ring 4 can provide a support point for controlling the cover 5.
[0037] The above design passes the top of the support base 9 through the strip-shaped groove 14 and the inner part of the rib plate 6. When the first nut 8 is threadedly connected with the first threaded rod 7, the roller 13 is pressed on the surface at the bottom of the long side of the packaging rib part 2. The inner wall of the cover 5 can be tightly attached to the outer wall of the condenser shell 1, ensuring the sealing effect of the cover 5 at the maintenance window 16 with the outer wall of the condenser shell 1. The rib ring 4 on the outer wall of the cover 5 can drive the cover 5 to slide on the top of the condenser shell 1, thereby opening the maintenance window 16, facilitating the confirmation of the external dirt of the pipeline 15 and the damage inside the condenser shell 1, and thus performing corresponding maintenance work according to the actual situation without causing too much impact on the actual production use.
