Embodiment 1

[0025] Such as figure 1 and figure 2 As shown, a petroleum sieve plate for filtering in the present invention includes a sieve plate 1 inclined to be arranged, and the sieve plate 1 is located between the inclined sieve machine longitudinal beam 3 and the inclined sieve machine beam 2, and the sieve plate 1 is opened There are a plurality of evenly arranged sieve holes 7, the cross-section of which is a parallelogram; the sieve holes 7 are provided with back ribs 8; and a connecting block 4 is also included, and the sieve plate 1 is connected to the longitudinal direction of the sieve machine through the connecting block 4. The beam 3 is connected; the connecting block 4 is made of rubber, the longitudinal beam 3 of the screen machine is provided with a groove 5, the connecting block 4 is placed in the groove 5, and the groove bottom of the groove 5 is provided with a threaded through hole, and the bolt 6 through the connecting block 4 and the threaded through hole; the vib...

Embodiment 2

[0028] Such as figure 2 As shown, a petroleum sieve plate for filtration of the present invention, the inclination angle 9 of the sieve plate 1 is 15° to 20°; The larger the capacity, the greater the processing capacity, but the lower the screening efficiency; setting the inclination of the sieve plate 1 within the range of 15°~20° can achieve an effective balance between the processing capacity and the screening efficiency. When the inclination is lower than 15°, the processing capacity of sieve plate 1 is too low, so that most of the drilling fluid cannot be screened out; when the inclination is higher than 20°, the screening efficiency of sieve plate 1 is too low, so that The sieve plate 1 is blocked, which affects the working efficiency.

Abstract

The invention discloses a petroleum sieve plate for filtration. The petroleum sieve plate for filtration comprises a sieve plate body which is arranged in an inclined mode, the sieve plate body is located between an inclined screening-machine longitudinal beam and an inclined screening-machine transverse beam and provided with a plurality of sieve holes which are arranged uniformly, and the section of each sieve hole is a parallelogram; a back rib is arranged between every two adjacent sieve holes. The petroleum sieve plate for filtration further comprises connection blocks, wherein the sieve plate body is connected with the screening-machine longitudinal beam through the connection blocks; the back ribs can fasten the sieve plate body, and work stability of the sieve plate body is guaranteed; sieve holes of a conventional sieve plate are perpendicular to the plane where the conventional sieve plate is located, however, the sieve holes of the petroleum sieve plate for filtration are perpendicular to the horizontal plane, the sieve-penetrating area is enlarged, and a screening effect is improved.

Description

technical field [0001] The invention relates to a vibrating screen, in particular to a petroleum sieve plate for filtering. Background technique [0002] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve, which is projected as a circle on the horizontal plane, and projected on the vertical plane as an ellipse. Adjusting the exciting force of the upper and lower rotating weights can change the vibration amplitude; and adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface. Vibrating screens are mainly divided into linear vibr...
