Description

Technical Field

[0001] This utility model relates to the field of natural gas equipment technology, and in particular to an easy-to-assemble high-pressure sand remover. Background Technology

[0002] During the extraction, processing, and transportation of natural gas, some solid particles, such as sand, soil, and construction residues, may be mixed in. When natural gas is transported under high pressure, these particles flow with the gas through critical equipment such as valves, instruments, and compressors, causing corrosion and wear to the core components of these devices. Therefore, high-pressure desanders are typically used to remove these solid particles. As an important component in natural gas-related equipment, a high-pressure desander mainly consists of a cylinder and internal components such as hydrocyclones and filters. There are usually multiple hydrocyclones. In current technology, when manufacturing high-pressure desanders, multiple hydrocyclones are typically welded directly onto a steel plate and then fixed into the cylinder, usually by welding. This assembly process is time-consuming. Utility Model Content

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-4 As shown, this example provides an easy-to-assemble high-pressure sand remover, including: a cylinder 100 and a sand removal assembly 200.

[0021] The inner wall of the cylinder 100 is provided with an installation ring 101; the sand removal assembly 200 includes a support plate 201 disposed in the cylinder 100 and mounted on the installation ring 101. The support plate 201 is provided with a plurality of hydrocyclones 202 that are spaced apart along the circumferential direction and arranged vertically. The periphery of the hydrocyclone 202 is provided with a retaining plate 203 for abutting against the top surface of the support plate 201. The support plate 201 is provided with a rotating ring 204 that rotates around its central axis. The inner side of the rotating ring 204 is provided with a plurality of positioning plates 205. When the hydrocyclone 202 is inserted into the support plate 201, the positioning plate 205 abuts against the top surface of the retaining plate 203, thereby providing a limit for the hydrocyclone 202.

[0022] Specifically, the mounting ring 101 has multiple through mounting holes 102 along the circumferential direction of its top surface, and the support plate 201 has multiple connecting blocks 206 along the circumferential direction on its bottom surface. The connecting blocks 206 pass through the mounting holes 102, so that the support plate 201 and the mounting ring 101 are relatively fixed.

[0023] Specifically, the bottom surface of the mounting ring 101 is provided with multiple protrusions 103 along the circumferential direction. A push rod 104 passes through the protrusions 103. The connecting block 206 has a positioning hole 207 on its side. The top of one end of the push rod 104 is arc-shaped and passes through the positioning hole 207. A baffle 105 is provided on the push rod 104, and a first spring 106 is fitted onto it. The baffle 105 is located between the protrusions 103 and the connecting block 206. The two ends of the first spring 106 abut against the protrusions 103 and the baffle 105 respectively, and are always in a compressed state. The other end of the push rod 104 is provided with... The first retaining ring 107 is used to abut against the protruding plate 103. During the process of placing the support plate 201 on the mounting ring 101, the lower end of the connecting block 206 will abut against the arc-shaped part of the push rod 104. As the support plate 201 continues to move downward, the connecting block 206 will force the push rod 104 to move. At this time, the first spring 106 is further compressed until the bottom surface of the support plate 201 contacts the top surface of the mounting ring 101. The push rod 104 will then pass into the positioning hole 207 under the action of the first spring 106, thereby fixing the support plate 201.

[0024] Specifically, the support plate 201 is provided with multiple arc-shaped grooves 208 along the circumferential direction. Arc-shaped guide rods 209 are provided along the trajectory of the arc-shaped grooves 208. A slider 210 is sleeved on the guide rod 209. The slider 210 is installed on the outer wall of the rotating ring 204, thereby providing a guiding effect for the rotation of the rotating ring 204. After the hydrocyclone 202 passes through the support plate 201, the rotating ring 204 can be rotated, moving the positioning plate 205 above the clamping plate 203, thereby limiting the vertical position of the hydrocyclone 202.

[0025] Specifically, one of the sliders 210 has a protruding rod 211 at its top, and a pressure plate 212 is fitted on the protruding rod 211. One end of the pressure plate 212 is fitted on the vertical rod 213, which is mounted on the support plate 201. A second retaining ring 214 is provided at the upper end of the vertical rod 213, and a second spring 215 is fitted on the vertical rod 213. The two ends of the second spring 215 abut against the pressure plate 212 and the second retaining ring 214 respectively, and are always in a compressed state. After the positioning plate 205 is positioned on the clamping plate 203, the pressure plate 212 is moved upward, and the second spring 215 is further compressed. Then, the rotating ring 204 continues to rotate at a certain angle, so that the slider 210 is located at one end of the arc groove 208. Then, the pressure plate 212 is released, and the pressure plate 212 will be fitted on the vertical rod 213 to fix the rotating ring 204 and prevent the positioning plate 205 from being moved away from the clamping plate 203.

[0026] Specifically, the top surface of the support plate 201 is provided with a plurality of protrusions 216, which pass through the clamping plate 203 to prevent the hydrocyclone 202 from rotating, thereby further fixing the hydrocyclone 202 and preventing the clamping plate 203 from moving out of the area below the positioning plate 203, ensuring the stable installation of the hydrocyclone 202, and also preventing the hydrocyclone 202 from rotating under the action of external force and causing damage to other components.

[0027] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
