Embodiment Construction

[0027] Combine below figure 2 and image 3 , the present invention is further described:

[0028] Such as figure 2 As shown, a piston diaphragm pump piston rod separation device for pumping iron concentrate slurry includes a hoop 4, a pull rod 5, a fixed ring 6, and a movable buckle 7. The hoop 4 is spliced ​​by two semicircular metal rings through the movable buckle 7, and the circumference of the hoop 4 can be adjusted within a certain range by adjusting the movable buckle 7. The adjustable design of the 4 circumferences of the hoop makes the separation device of the present invention have the advantages of convenient operation and suitable for piston rods of different diameters.

[0029] The hoop 4 is sleeved in the annular groove 9 of the piston rod 1, and the two ends of the hoop 4 are respectively connected to a fixing ring 6 through a tie rod 5, and the two fixing rings 6 are respectively sleeved on two different screw rods 8 and are The nut on the screw rod 8 can...

Abstract

The invention relates to a piston rod separation device of a piston-diaphragm pump as well as the piston-diaphragm pump. When a piston rod (1) is separated from a driving connecting rod (2), the piston rod (1) is connected with a screw (8) through the piston rod separation device of the piston-diaphragm pump to form a traction fixing end; and one end of the driving connecting rod (2) is acted by a traction force to form a traction force applying end. According to the invention, the piston rod and the screw are fixed together through the piston rod separation device of the piston-diaphragm pump, so that when the traction force is applied to a jigger, the piston rod is easily separated from the driving connection rod; and the piston rod and the driving connection rod which are tightly combined can be separated quickly and effectively, so that the maintenance and the overhaul are facilitated.

Description

technical field [0001] The invention relates to a piston rod separation device and a piston diaphragm pump of a piston diaphragm pump, in particular to a piston rod separation device and a piston diaphragm pump for pumping iron concentrate slurry. Background technique [0002] Piston diaphragm pump is an important equipment for long-distance slurry pipeline transportation, especially involving high-pressure slurry pipeline transportation. [0003] Such as figure 1 Shown is a schematic diagram of the existing piston diaphragm pump piston rod connection. The piston rod 1 of the piston diaphragm pump is connected with the driving connecting rod 2 through the fixed slider 3. The connecting ends of the piston rod 1 and the driving connecting rod 2 are respectively provided with annular grooves, and the fixed slider 3 is also correspondingly provided with protrusions snapped into the ring. in the groove. [0004] Usually, the piston rod 1 and the driving connecting rod 2 can be...
