Description

Technical Field

[0001] The utility model relates to an anti-clogging spraying device for processing cast iron pipelines, belonging to the technical field of spraying devices for processing cast iron pipelines. Background Art

[0002] During the processing of cast iron pipes, the outer surface of the pipes needs to be sprayed to avoid corrosion of the cast iron pipes. For example, the anti-clogging spray device for cast iron pipe processing mentioned in the authorization announcement number CN216173500U includes an outer frame, a spray structure and a storage box. The spray structure is installed on the top of the outer frame, and a connecting valve is provided on the top of the spray structure. One end of the connecting valve is connected to a filter assembly, and a pressure pump is installed on the top of the storage box. The input end of the pressure pump is connected to the inside of the storage box, and the output end of the pressure pump is connected to one end of the filter assembly through a hose.

[0003] In this device, the cast iron pipe is driven by the rotation of the transmission wheel, and then the spray material enters the nozzle for spraying. During the actual application process, the researchers found that during the spraying process, the support in contact with the outer surface of the cast iron pipe resulted in poor spraying effect, and the nozzle could not be cleaned and brushed conveniently and labor-savingly, and condensation and blockage were prone to occur.

Example 2:

[0029] See also Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that:

[0030] One end of the threaded rod 5 is fixedly connected to the output end of the servo motor 4, and the end of the threaded rod 5 away from the servo motor 4 is movably connected to the guide rail box 3 through a bearing; the bottom surface of the movable frame 6 is fixedly connected to a sliding block 20, and the sliding block 20 is threadedly connected to the outer surface of the threaded rod 5, and the top surface of the guide rail box 3 is provided with a sliding groove that matches the structural size of the sliding block 20; the servo motor 4 is controlled to drive the rotation of the threaded rod 5, and as the rotation direction of the threaded rod 5 is different, the movable frame 6 is moved closer to or away from the fixed frame 7.

[0031] It should be noted that: all electrical components in this case are connected to their corresponding power supplies through wires by personnel in this field, and appropriate controllers, such as PLC controllers or single-chip microcomputers, should be selected according to actual conditions to meet control requirements.
