Description

Technical Field

[0001] The utility model belongs to the technical field of sealing covers, and particularly relates to a sealing assembly for an oilfield vibrating screen. Background Art

[0002] During the oilfield exploitation process, it is necessary to use a vibrating screen to vibrate and screen some fuel ores. The vibrating screen is a device used to screen and select powder materials or liquid materials containing particulate matters. It vibrates the screening device above through the vibrating base at the bottom, so that the materials pass through the sieve to achieve classification screening.

[0003] Most of the traditional vibrating screens are open type and do not have corresponding sealing components. Dust will be generated during the vibrating screening process in oilfield exploitation. On the one hand, it pollutes the production environment, and on the other hand, it will affect the physical health of workers if inhaled. Therefore, we urgently need to invent a sealing component for oilfield vibrating screens. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] The utility model relates to a sealing assembly for an oilfield vibrating screen, which includes a sealing cover. One side of the top of the sealing cover is provided with a feeding hopper, and a hopper door is rotatably installed on the feeding hopper. Both sides of the sealing cover are provided with openings, and adjusting components are arranged on the openings. The adjusting component includes a slide rail, a baffle plate and a driving motor. The driving motor is fixedly installed on the sealing cover, and the output end is fixedly installed with a driving lead screw. The driving lead screw is threadedly connected with the baffle plate. An installation plate is integrally formed on the outer side of the top of the baffle plate. The air extraction component includes a collection box and a suction seat. The top of the collection box is fixedly installed with an air extraction pump, and the output end of the air extraction pump is fixedly communicated with the collection box. The input end of the air extraction pump is fixedly communicated with a shunt pipe. There are two suction seats, which are respectively fixedly installed on the tops of the two installation plates. Connecting hoses are fixedly communicated between the shunt pipe and the two suction seats.

[0006] As a preferred technical solution of the utility model, an observation window is opened at the front end of the sealing cover, and the observation window is made of high-strength tempered glass. A suitable sealing gasket is fixedly bonded to the bottom of the sealing cover.

[0007] As a preferred technical solution of the utility model, there are two slide rails, which are respectively fixedly installed on both sides of the opening. Sliders are arranged at both ends of the baffle plate, and the baffle plate is slidably installed on the two slide rails through the sliders.

[0008] As a preferred technical solution of the utility model, a plurality of through holes are equidistantly opened on the installation plate, and a plurality of suction heads are arranged at the bottom of the suction seat, and the suction heads penetrate through the through holes on the installation plate.

[0009] As a preferred technical solution of the utility model, the collection box is fixedly mounted on the back of the sealing cover and a box door is fixedly mounted on the collection box by bolts.

[0010] The beneficial effects achieved by the utility model are:

[0011] Open the hopper and feed materials manually through the feeding hopper. The opening setting can match the vibrating screening machine with conveying function, which improves the versatility. The forward and reverse rotation of the driving motor drives the driving screw to drive the baffle to rise and fall, and the self-locking function of the driving motor is used for positioning, so as to achieve the purpose of adapting to the use of vibrating and screening objects of different sizes, which improves the versatility. During the use of the vibrating screening machine, part of the raised dust is confined in the sealing cover, and the vacuum pump is used for vacuuming. The other part of the dust will enter the collection box through the suction head, the connecting hose and the diversion pipe for centralized collection, which can effectively improve the quality of the production environment.
