Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily implement the present invention. The present invention can be implemented in various different ways, and is not limited to the embodiments described below.
It is noted that the drawings are exemplary and are not drawn to scale. Relative dimensions and proportions between parts shown in the drawings have been shown exaggerated or reduced in size, for the sake of clarity and convenience in the drawings, any dimensions being exemplary only and not intended to limit the invention. In addition, in order to show similar features, the same components, elements, or parts shown in two or more drawings are denoted by the same reference numerals.
The embodiments of the present invention specifically show the preferred embodiments of the present invention. As a result, various modifications can be envisioned as shown in the drawings. Thus, embodiments are not limited to the particular manner in which the regions illustrated are modified, including for example, by variations in the manner in which the fabrication occurs.
The spray coating device 100 for a polyurethane-coated spheroidal graphite cast iron pipe according to an embodiment of the present invention is described below with reference to the drawings.
Referring to fig. 1, a spray coating apparatus 100 for a polyurethane-coated ductile iron pipe according to an embodiment of the present invention includes a spray pipe 110, coupling teeth 113, and a nozzle 114.
The nozzle 110 is annular and has an annular cavity 111 therein.
Specifically, the inner surface 112 and the outer surface of the nozzle 110 are coaxial, the cavity 111 of the nozzle 110 is an annular cavity, the spraying raw material is filled into the cavity 111 through the feed inlet 116, the high-pressure gas is filled into the cavity 111 through the gas inlet 117, the spraying raw material is sprayed out through the nozzle 114 under the action of the high-pressure gas, the nodular cast iron pipe penetrates through the inside of the nozzle 110, and the spraying raw material is uniformly sprayed on the outer surface of the nodular cast iron pipe through the nozzle 114.
Specifically, the connecting teeth 113 are uniformly distributed on the outer surface of the nozzle tube 110 and engaged with an external driving device (not shown in the figure), and the nozzle tube 113 rotates around the axis thereof under the driving of the external driving device, and the nozzle 114 synchronously rotates around the outer circumferential surface of the nodular cast iron pipe along with the nozzle tube 110, so as to further ensure the uniformity of spraying.
The nozzles 114 are formed on the inner surface 112 of the nozzle 110 and are uniformly distributed along the circumferential direction of the inner surface 112, the inner surface 112 is an arc surface concave to the cavity 111, and baffles 115 extending towards the inner side of the nozzle 110 are arranged on two sides of the inner surface 112.
Specifically, the middle of the inner surface 112 is concave to the cavity 111 side, and both sides of the inner surface 112 are located on the same circumference, i.e., both sides of the inner surface 112 have the same height.
As an example, nozzles 114 are evenly distributed at the center of inner surface 112.
In the embodiment, the baffle 115 is annular, the plane of the baffle 115 is flush with the plane of the nozzle 110, and the baffle 115 is coaxial with the nozzle 110.
For example, the baffles 115 are symmetrically disposed on both sides of the inner surface 112.
In the present embodiment, nozzle 114 is formed on inner surface 112, and the axis of nozzle 114 is disposed in the radial direction of nozzle 110.
As an example, the nozzle 114 is formed in a trumpet shape in cross section, that is, the nozzle 114 has enlarged open ends near both ends of the chamber 111 and the baffle 115, and the flow rate and the diffusion area of the spray raw material are increased when the spray raw material flows into the nozzle 114, so that each nozzle 114 can cover a large area of the surface of the ductile iron pipe.
In this embodiment, after the spraying material is sprayed out through the nozzle 114, the scattered part falls on the inner surface 112, and because the inner surface 112 adopts an arc surface and the baffle plates 115 are arranged on both sides of the inner surface 112, the spraying material can be collected on the inner surface 112 and sprayed on the surface of the nodular cast iron pipe again through the nozzle 114, thereby preventing the waste of the material and improving the utilization rate of the material.
In addition, in the process that the ductile cast iron pipe passes through the spray pipe 110, the spray pipe 110 is driven by an external driving device to rotate, and the spraying uniformity is guaranteed.
Compared with the prior art, according to the utility model discloses polyurethane coating spraying device 100 for nodular cast iron pipe can improve the degree of automation of spraying work, can improve spraying work efficiency.
