[0002] In the process of chemical production, the transportation of various materials is often involved, such as liquid materials, gaseous materials, powder materials, granular materials, and slurry materials with solid-liquid mixture, etc. For materials with strong fluidity, pipeline transportation is mostly used.

[0003] For materials transported by pipelines (such as slurry), in the actual transportation process, the pipeline cannot be a straight line, and it will produce a certain angle of bending in some places. For example, there is a bending of about 90 degrees at the connection between the horizontal pipeline and the vertical pipeline. At the bending place, the flow rate of the slurry will be affected and reduced, and it is also easy to cause blockage. The influence on materials with low water content is more obvious. Therefore, the pipeline needs to be cleaned frequently. Otherwise, blockage will be very troublesome, which will not only affect production efficiency but also require a lot of labor. Therefore, it is necessary to design a pipeline connection device that can reduce the blockage rate. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pipeline connection assembly for preventing material blockage, which can effectively reduce the probability of blockage at the connection of the pipeline when transporting slurry.

[0005] The utility model is realized through the following technical solutions: The pipeline connection assembly for preventing material blockage of the utility model includes a horizontal cross pipe, a vertical pipe vertically arranged above the cross pipe, a connecting pipe for connecting the cross pipe and the vertical pipe, and a gas supply device communicated with the upper end of the connecting pipe; the connecting pipe is inclined, and the gas supply device includes an air inlet pipe arranged on the side wall of the upper end of the connecting pipe and a gas compressor connected to the air inlet pipe.

[0006] Further, the gas supply device further includes a hollow air inlet plate communicated with the side wall of the upper end of the connecting pipe; one end of the air inlet plate close to the connecting pipe is an open end, the open end of the air inlet plate is communicated with the inside of the connecting pipe, and the other end is communicated with the air inlet pipe.

[0007] Further, the length direction of the air inlet plate is parallel to the axial direction of the connecting pipe.

[0008] Further, the projection of the air inlet plate along the cross section perpendicular to its length direction is arc-shaped, and the air inlet plate is arranged close to the lower side of the connecting pipe.

[0009] Further, the air supply device further includes an air storage tank provided on the side wall of the vertical pipe, and a first air duct for connecting the air storage tank and the air compressor; the air inlet pipe is communicated with the lower end of the air storage tank, and a pressure valve is provided at the connection between the air storage tank and the air inlet pipe.

[0013] The technical solution of the present utility model has at least the following advantages and beneficial effects: The pipeline connection component for preventing material blockage of the present utility model uses a vertical pipe, a horizontal pipe and a connecting pipe to transport slurry during use. By setting the connecting pipe, the included angles between the connecting pipe and the vertical pipe, and between the connecting pipe and the horizontal pipe can be significantly increased (such as increasing from 90 degrees to 135 degrees, and the increased angle can improve the flow efficiency of the material and reduce the probability of blockage).

Specific embodiments

[0021] Embodiment

[0022] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 5 As shown, the pipeline connection assembly for preventing material blockage in this embodiment includes a horizontally arranged horizontal pipe 12, a vertical pipe 11 vertically arranged above the horizontal pipe 12, a connecting pipe 20 for connecting the horizontal pipe 12 and the vertical pipe 11, and a gas supply device communicated with the upper end of the connecting pipe 20; the connecting pipe 20 is inclined, and the gas supply device includes an air inlet pipe 22 arranged on the side wall of the upper end of the connecting pipe 20, and a compressor connected to the air inlet pipe 22. Specifically, the horizontal pipe 12 and the connecting pipe 20, and the vertical pipe 11 and the connecting pipe 20 can be connected by flanges. During use, the slurry is transported through the vertical pipe 11, the horizontal pipe 12 and the connecting pipe 20. By arranging the connecting pipe 20, the included angles between the connecting pipe 20 and the vertical pipe 11, and between the connecting pipe 20 and the horizontal pipe 12 can be significantly increased (such as increasing from 90 degrees to 135 degrees. The increase in the angle can improve the flow efficiency of the material and reduce the probability of blockage). During the transportation process, high-pressure gas can be continuously or intermittently introduced into the connecting pipe 20 through the compressor. The slurry blocked in the connecting pipe 20 can be washed away by the high-pressure gas. For the slurry with a low water content, the flow efficiency of the slurry can also be improved by the push of the gas. Reduce the probability of slurry blockage in the pipeline.

[0023] The air supply device in this embodiment further includes a hollow air inlet plate 21 communicated with the side wall of the upper end of the connecting pipe 20; one end of the air inlet plate 21 close to the connecting pipe 20 is an open end, the open end of the air inlet plate 21 is communicated with the inside of the connecting pipe 20, and the other end is communicated with the air inlet pipe 22. The length direction of the air inlet plate 21 is parallel to the axial direction of the connecting pipe 20. The projection of the air inlet plate 21 along the cross-section perpendicular to its length direction is arc-shaped, and the air inlet plate 21 is arranged close to the lower side of the connecting pipe 20. Specifically, using the air inlet plate 21 to send high-pressure gas into the connecting pipe 20 can increase the gas flow area, thereby increasing the action area between the gas and the slurry, improving the coverage area of the gas on the bottom wall of the connecting pipe 20, and enhancing the pushing effect of the gas on the slurry.

[0024] The air supply device in this embodiment further includes an air storage tank 23 arranged on the side wall of the vertical pipe 11, and a first air guide pipe 25 for connecting the air storage tank 23 and the air compressor; the air inlet pipe 22 is communicated with the lower end of the air storage tank 23, and a pressure valve 24 is arranged at the connection between the air storage tank 23 and the air inlet pipe 22. Specifically, by setting the air storage tank 23 and the pressure valve 24, the air compressor can continuously send high-pressure gas into the air storage tank 23, and when the air pressure reaches a certain level, it can enter the air inlet pipe 22 through the pressure valve 24 to achieve intermittent air intake operation, thus reducing the load on the air compressor.

[0025] In this embodiment, it further includes a water injection device connected to the air inlet plate 21; the water injection device includes a water storage tank 26 arranged on the side wall of the vertical pipe 11, a water inlet pipe 29 connected to the upper end of the water storage tank 26, a second air guide pipe 28 for connecting the water storage tank 26 and the air compressor, and a water injection pipe 27 for connecting the water storage tank 26 and the air inlet plate 21. Specifically, water injection and air injection can be carried out synchronously or independently. The air compressor pressurizes the water storage tank 26 through the second air guide pipe 28, and the water in the water storage tank 26 can be injected into the air inlet plate 21 through the water injection pipe 27 and finally enter the connecting pipe 20. The purpose of water injection is to lubricate the bottom wall of the connecting pipe 20. For some slurries with low water content, it can better promote their flow, and the injected water only needs to cover the inner bottom wall of the connecting pipe 20, so the amount of water added is extremely small and hardly affects the original slurry.

[0026] The air storage tank 23 and the water storage tank 26 in this embodiment are both connected to the vertical pipe 11 through a hoop 211.

[0027] A pair of filter plates 210 are arranged inside the air inlet plate 21 in this embodiment, and the pair of filter plates 210 are distributed along the length direction of the air inlet plate 21. Specifically, the function of the filter plates 210 is to prevent the slurry in the connecting pipe 20 from flowing back into the air inlet plate 21.

[0028] In summary, for the pipeline connection component for preventing material blockage in this embodiment, when in use, the slurry is conveyed through the vertical pipe 11, the horizontal pipe 12 and the connecting pipe 20. By setting the connecting pipe 20, the included angles between the connecting pipe 20 and the vertical pipe 11 and between the connecting pipe 20 and the horizontal pipe 12 can be significantly increased. During the conveying process, high-pressure gas can be continuously or intermittently introduced into the connecting pipe 20 through a pneumatic machine. The slurry blocked in the connecting pipe 20 can be washed away by the high-pressure gas. For the slurry with a low water content, the flow efficiency of the slurry can also be improved by the pushing of the gas, reducing the probability of slurry blockage in the pipeline.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
