Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a filter-type sand removal device. Background Art

[0002] Petroleum, a primary target of geological exploration, is a viscous, dark brown liquid known as the "blood of industry." Petroleum is deposited in parts of the Earth's upper crust. Its primary components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Sand removal devices are used in the petrochemical industry to remove sand and gravel particles introduced during the flow of liquids or gases. Their primary function is to protect downstream equipment by preventing sand and gravel particles from causing wear or blockage on pipes, pumps, valves, and other equipment, thereby ensuring normal system operation and extending equipment life.

[0003] In the process of realizing this application, the inventor discovered that the prior art has the following problems: At present, most of the existing sand removal devices use a single filter screen to filter and discharge the gravel when filtering and cleaning the sand and gravel carried in the oil transportation. Because the bottom of the filter screen encounters a large amount of sand and gravel for transportation and filtering, it may cause the sand removal device to be difficult to filter and discharge the sand and gravel in time, thereby causing the filter screen to be blocked. Therefore, those skilled in the art have provided a filter screen type sand removal device to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art, and the proposed filter-type sand discharge device, after clamping and arranging water pipes on the inner and outer surfaces of the sand discharge pipe, can be fixedly provided with an umbrella-shaped filter screen on the outer surface of the water pipe near the upper end, and at the same time, the upper end of the umbrella-shaped filter screen can be arranged on the upper end of the inner bottom surface of the sand filter pipe to filter sand and gravel. When the umbrella-shaped filter screen is blocked, the water flow in the water pipe can be used to flush the inner surface of the umbrella-shaped filter screen, which can effectively prevent the umbrella-shaped filter screen from being blocked.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The filter screen type sand discharge device comprises a sand filter cylinder, a sand filter tube is embedded in the inner surface of the sand filter cylinder near the lower end, a cover plate is provided on the upper end surface of the sand filter cylinder, a detachable sleeve is clamped on the lower end surface of the cover plate, and a sand discharge tube is clamped on the lower end surface of the sand filter cylinder;

[0007] A water pipe is clamped on the inner surface of the sand discharge pipe, and an umbrella-shaped filter screen is fixedly provided on the upper end of the outer surface of the water pipe.

[0008] Furthermore, a rubber ring is embedded in the upper end surface of the sand filter cylinder, and the detachable sleeve is movably embedded in the upper end of the inner surface of the sand filter cylinder.

[0009] Furthermore, a conveying port is provided on one side of the outer surface of the sand filter cylinder near the upper end, and an output port is provided on the other side of the outer surface of the sand filter cylinder near the lower end.

[0010] Furthermore, a clamp is provided on the upper end of the outer surface of the sand filter cylinder and the lower end of the outer surface of the cover plate, and a hanging ring is threadedly embedded at the midpoint of the upper end surface of the cover plate.

[0011] Furthermore, a discharge port is provided at the midpoint of the lower end surface of the sand discharge pipe, and the umbrella-shaped filter screen is embedded in the bottom surface of the sand filter pipe near the upper end.

[0012] Furthermore, the lower end plane of the umbrella-shaped filter screen is fixedly connected to the upper end of the outer surface of the water pipe, and the upper end arc surface of the umbrella-shaped filter screen is located inside the sand filter pipe.

[0013] The utility model has the following beneficial effects:

[0014] 1. The filter-type sand discharge device proposed by the utility model can be clamped and fixedly arranged on the lower end surface of the sand filter cylinder by clamping the sand discharge pipe, and then a water pipe can be clamped and arranged inside the sand discharge pipe. After the water pipe is clamped and arranged in the sand discharge pipe, an umbrella-shaped filter can be fixedly arranged on the upper end of the outer surface of the water pipe. At the same time, the upper end opening of the water pipe is arranged inside the umbrella-shaped filter. After the umbrella-shaped filter is arranged on the inner bottom surface of the sand filter pipe, the sand and gravel transported to the sand filter cylinder for filtration can be filtered. When the umbrella-shaped filter is blocked, the water pipe can be used to flush the inner surface of the umbrella-shaped filter through water flow, thereby loosening the blocked sand and gravel, which can be discharged from the mesh of the umbrella-shaped filter to realize the sand discharge process.

[0015] 2. The filter screen type sand discharge device proposed by the utility model can filter the liquid transported therein by embedding a sand filter tube in the inner surface of the sand filter tube. At the same time, the cover plate movably arranged on the upper end surface of the sand filter tube can be clamped and fixed by a clamp provided on the outer surface, so that the cover plate can be clamped and fixed to the upper end surface of the sand filter tube. At the same time, the detachable sleeve clamped on the lower end surface of the cover plate can be replaced and cleaned after the cover plate and the sand filter tube are separated, and the embedded sand filter tube can also be taken out for maintenance and cleaning.
