Description

Technical Field

[0001] The utility model relates to the field of assembleable screens for oil exploitation, in particular to an assembleable screen for oil exploitation. Background Art

[0002] Petroleum screen is a metal mesh structure element used for screening and filtering. It has high strength, rigidity and load-bearing capacity. It can be made into various shapes of rigid screening and filtering devices. It is widely used in screening, filtering, dehydration, desludging and other operations in many industries.

[0003] The existing patent CN220248028U discloses a quick-detachable vibrating screen for use with oil drills. The operator rotates the rotating rod to a vertical state, and then pulls the handle to drive the scraper to scrape the sticky mud on the top of the filter screen to complete the cleaning of the top of the filter screen. After completion, the scraper is slid to the top of the mounting frame, and then the rotating rod is reset to fix the handle. When the solid and liquid of the petroleum mud are filtered, the liquid passes through the filter holes of the filter screen, and the angle between the two mounting frames is formed. The solid slides into the collection tank due to the inclination of the mounting frames. When the filter screen needs to be replaced, the screws are removed by rotating, and then the sliding parts on the two connecting platforms are pulled to disengage the sliding parts from the card holes. After all the card blocks are pulled out, the two mounting frames are separated, and then the filter screen is removed from the vibrating screen for maintenance.

[0004] When the existing device cleans the screen, the sticky mud on the top of the filter screen is scraped off by a scraper bar. During the scraping process, part of the mud will be squeezed out to the bottom of the filter screen, thereby flowing out of the filter screen. Utility Model Content

[0005] The purpose of the utility model is to provide an assembleable screen for oil extraction in order to solve the problem that when the sticky mud on the top of the filter screen is scraped off by a scraper bar, part of the mud will be squeezed out to the bottom of the filter screen during the scraping process, thereby flowing out of the filter screen.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembleable screen for oil extraction, characterized in that a wedge-shaped frame is arranged on the top of the main body, fixed columns are fixed on both sides of the inside of the wedge-shaped frame, multiple groups of arc blocks of different sizes are arranged inside the fixed columns, multiple groups of contacting extrusion columns are arranged on one side of the arc block, and screens are arranged on both sides of the top of the wedge-shaped frame.

[0007] As a further solution of the utility model: two sets of motors are installed at one end of the wedge-shaped frame, and a screw is fixed at the output end of the motor. The mud in the screen falls on the surface of the base. Because the screw contacts the bottom of the screen, the screen is driven to shake when the screw rotates.

[0008] As a further solution of the utility model: a slide plate is arranged on the outer side of the screw rod, an arc ring is arranged inside the slide plate, and the fixing column passes through the slide plate.

[0009] As a further solution of the utility model: the arc ring is located on the outside of the fixed column, the extrusion column is slidably connected to the outside of the arc ring, and the extrusion column is squeezed by arc blocks of different sizes when moving, so that multiple groups of extrusion columns move up and down, and a base is provided on the top of the arc ring.

[0010] As a further solution of the utility model: the starting motor rotates to drive the screw to rotate, the screw drives the slide plate to move, the slide plate drives the arc ring and the extrusion column to move, and one side of the bottom of the base contacts the outer side of the screw.

[0011] As a further solution of the utility model: No. 1 grooves are provided on both sides of the top of the main body, and sliders are fixed at both ends of the screen.

[0012] As a further solution of the utility model: the bottom of the slider is rotatably connected to a hydraulic rod, which controls the hydraulic rod to push the slider upward, and the slider drives the screen to rotate, so that the screen is vertical. The hydraulic rod is installed inside the main body, and a rotating shaft is set between the screen and the main body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The motor is set to rotate to drive the screw to rotate, and the screw drives the slide to move. The slide drives the arc ring and the extrusion column to move, and the bottom of the screen is beaten. Because the screw contacts the bottom of the screen, the screen is shaken when the screw rotates, so that the mud on the surface of the base falls into the No. 1 slot for discharge;

[0015] 2. The slider is pushed upward by the set control hydraulic rod, and the slider drives the screen to rotate, so that the screen is vertical, which is convenient for cleaning and maintenance of the top and bottom of the screen. BRIEF DESCRIPTION OF THE DRAWINGS
