Embodiment Construction

[0014] figure 1 As shown, the specific implementation is as follows:

[0015] A wet spray pipe for a wet spraying machine, comprising a tapered pipe body 2, the large end of the tapered pipe body 2 is provided with a joint 1, and the small end of the tapered pipe body 2 is provided with a variable diameter joint 3. The side wall of the tapered pipe body 2 is provided with an air inlet valve 4 and a cleaning column inlet 5, and a plug core 6 is arranged on the cleaning column inlet 5, and the air inlet valve 4 is located above the cleaning column inlet 5, and the air inlet valve 4 The distance from the joint 1 is 1 / 3-2 / 3 of the length of the side wall, and the included angle between the centerline of the cleaning column inlet 5 and the centerline of the tapered pipe body 2 is 20-45°.

[0016] The intake valve 4 is a ball valve.

[0017] The distance between the inlet valve 4 and the joint 1 is 1 / 2 of the length of the tapered pipe, which is the best position.

[0018] The in...

Abstract

A wet spray pipe for a wet type pulp shooting machine comprises a conical pipe body. A connector is arranged at the large end of the conical pipe body, a reducer connector is arranged at the small end of the conical pipe body, an air inlet valve and a cleaning column inlet are arranged on the lateral wall of the conical pipe body, a plug core is arranged on the cleaning column inlet, the air inlet valve is arranged above the cleaning column inlet, the distance between the air inlet valve and the connector is 1 / 3 to 2 / 3 of the length of the conical pipe, and an included angle between the central line of the cleaning column inlet and the central line of the conical pipe body is 20 to 45 degrees. The wet spray pipe is simple in structure reasonable in design, convenient to process and manufacture and low in cost, can conveniently and quickly clean spray pipes, saves time and labor, simultaneously improves work efficiency and avoids labor loss caused by dismounting spray pipes.

Description

technical field [0001] The invention relates to a spraying device for a wet spraying machine, in particular to a wet spraying pipe for a wet spraying machine. Background technique [0002] Wet shotcrete machine is currently the anchor shotcrete supporting machine with good comprehensive performance in reducing dust, reducing rebound rate and saving materials at home and abroad. The basic principle of the so-called wet spraying is to add the concrete mixed with water into the wet spraying machine, transport it to the spray head, and form a beam of material sprayed on the construction surface after being mixed with accelerator. [0003] Wet shotcrete machines are generally used in underground operations in mining areas, and are also called mine wet shotcrete machines. In fact, the wet spraying machine has a wide range of uses, and can be widely used in concrete mixing, transportation, and spraying projects such as mines, railways, highways, culverts, bridges, and urban constr...
