Description

Technical Field

[0001] The utility model relates to the technical field of pipeline splash prevention, in particular to a liquid conveying pipeline splash prevention device. Background Art

[0002] On the pipeline connected to the reactor, the pipe joints are pressure-bearing parts, so liquid leakage and splashing may occur. In order to contain the impact range of splashing when the liquid leaks and splashes, anti-splashing devices are often installed at the joints that are subject to greater pressure. Ordinary anti-splashing devices adopt a structure that can be separated and disassembled, and cover the joints with a simple shield structure, so that it can play a blocking role when the liquid splashes. However, ordinary anti-splashing devices have a larger opening at the connection with the pipeline, and the overall internal space is much larger than the volume of the joint. This provides conditions for the liquid to splash out from the joint. At the same time, the leaked liquid splashing everywhere not only affects the production environment and is difficult to clean, but also causes a waste of cost.

[0003] Therefore, designing a double-layer device to block the space at the shrinkage joint, reduce the probability of liquid splashing outward, guide the leaked liquid for recovery, and reduce cost losses is exactly the problem that the inventor wants to solve. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is a further description of the present invention in conjunction with specific embodiments. These embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0019] See also Figures 1 to 2 This is a structural view of the utility model and a view of the internal structure of the protective cover, a liquid conveying pipeline splash prevention device, including an outer cover, the outer cover includes an upper cover 1 and a lower cover 2 which are hinged to each other, a buckle structure 3 is provided at the seam at one end of the upper cover 1 and the lower cover 2, and a sealing strip 4 is provided at the seam at one end of the upper cover 1 and the lower cover 2. By opening or closing the buckle, the upper cover 1 and the lower cover 2 can be flipped around the hinge for disassembly and assembly.

[0020] The inner sides of the upper cover 1 and the lower cover 2 are both provided with symmetrically distributed inner covers 10. The inner covers 10 arranged on the inner sides of the upper cover 1 and the lower cover 2 on the same side are connected to form a complete conical structure. The tip of the conical structure is provided with a first through hole 14, and the inner side of the first through hole 14 passes through the pipe. In order to effectively prevent the liquid from splashing outward along the joint, the inner diameter of the first through hole 14 is larger than the outer diameter of the pipe and the difference between the inner diameter of the first through hole 14 and the outer diameter of the pipe is not more than 5mm. The gap is limited to within 5mm, which can effectively filter out most of the splashing liquid. The end of the inner cover 10 close to the axis is convex in the direction close to the guide groove 9. The inclined surface formed by the cone can effectively guide the splashed liquid into the guide groove 9, which is convenient for subsequent recycling and processing. The liquid blocked by the inner cover 10 loses its initial impact force on the outer cover, and the splashing path is also blocked, so the outer cover can well prevent the liquid from splashing to the outside.

[0021] In order to increase the strength of the inner cover 10 and reduce the deformation between the inner cover 10 and the outer cover, reinforcing ribs 11 are connected between the inner cover 10 and the outer cover.

[0022] The inner sides of the upper cover 1 and the lower cover 2 are provided with guide grooves 9, the lower end of the guide groove 9 arranged on the inner side of the lower cover 2 is provided with a discharge port 12, the outer side of the discharge port 12 is threadedly connected with a pipe joint 5, the lower end of the pipe joint 5 is connected with a recovery pipe 6, and the lower end of the recovery pipe 6 is connected with a recovery box 7. The liquid splashed from the pipe joint passes through the blocking and diversion of the inner cover 10 and the outer cover, and returns to the guide groove 9. Under the influence of gravity, the liquid returns to the discharge port 12 and enters the recovery box 7 through the recovery pipe 6 to wait for processing.

[0023] If the axis of the butted pipes is vertically arranged, the corresponding guide groove 9 can be arranged at the connecting edge of the inner cover 10 and the outer cover, so that the guided liquid can smoothly pass through the guide groove 9 into the discharge port 12.

[0024] Second through holes 15 are provided at both the left and right ends of the outer cover for passing the pipeline.

[0025] In order to prevent leakage of the pipe joint 5 when recovering the liquid, a sealing gasket 13 is provided between the pipe joint 5 and the discharge port 12 .

[0026] A box liquid level sensor 8 is arranged on the inner side of the upper side wall of the recovery box 7. When the liquid inside the recovery box 7 is almost full, the box liquid level sensor 8 will be triggered to send an electrical signal, and the electrical signal will be transmitted to the alarm or controller for warning. In order to better monitor the liquid splashing situation, a liquid sensor is arranged on the side wall of the outer cover to monitor the inside of the outer cover, and an electrical signal alarm will be sent out once liquid appears.

[0027] The utility model is provided with an inner cover 10 with a conical structure inside to cooperate with the outer cover to block the liquid. The liquid is guided into the guide groove 9 by the inclination of the cone surface so as to be recovered and processed, thereby reducing the gap size at the joint between the inner cover 10 and the pipeline, realizing the function of double-layer blocking and shrinking the space at the joint, reducing the probability of liquid splashing outward, guiding the leaked liquid for recovery, and reducing cost losses.
