Detailed Description

The present application is described in further detail below with reference to figures 1-2.

Referring to fig. 1 and 2, the embodiment of the application provides a pulverized coal screening device for vanadium-titanium pellet production, which comprises a rack 1 and a screening cylinder 2 vertically fixed on the rack 1, wherein the screening cylinder 2 is of an upper opening structure and is covered with a cylinder cover 21, and the cylinder cover 21 is fixedly connected with the screening cylinder 2 through bolts; a plurality of feed inlets 211 are formed in the cylinder cover 21 in a penetrating manner along the thickness direction of the cylinder cover, so that the pulverized coal to be screened is added into the screening cylinder 2 through the feed inlets 211; to facilitate the addition of pulverized coal, a hopper 212 is connected to the feed port 211. One end of the screening cylinder 2 close to the ground is in an inverted cone shape, and is vertically communicated with a discharge pipe 22, so that the screened coal powder in the screening cylinder 2 can be discharged through the discharge pipe 22; a receiving trough 221 is arranged in advance on one side of the discharge pipe 22 close to the ground so as to collect and store the pulverized coal falling from the discharge pipe 22.

An annular groove 23 is formed in the inner wall of the sieving cylinder 2 in the circumferential direction. The screening cylinder 2 is internally and transversely provided with a filter plate 3, the filter plate 3 is provided with a plurality of filter holes 31 in a penetrating way along the thickness direction, the aperture of each filter hole 31 is only slightly larger than the particle size of the coal powder, so that the coal powder entering the screening cylinder 2 through the feed inlet 211 can pass through, and the coal blocks are retained on the filter plate 3; the circumferential side of the filter plate 3 is integrally formed with a ring block 32, and the ring block 32 is adapted and clamped in the ring groove 23 to clamp and fix the filter plate 3 to the sieving cylinder 2.

In order to enhance the screening effect, the screening cylinder 2 is further provided with a driving assembly 4, the driving assembly 4 comprises a shaft rod 41 and a driving part 42, one end of the shaft rod 41 is fixed at the axial lead of the filter plate 3, the other end of the shaft rod 41 vertically extends and is rotatably connected to the cylinder cover 21, and one end of the shaft rod 41 rotatably connected to the cylinder cover 21 penetrates through the cylinder cover 21; the driving member 42 is a motor fixed on the cover 21, and its output end is coaxially fixed on one end of the shaft 41 penetrating through the cover 21. When the screening work is carried out, the coal powder to be screened is added into the screening cylinder 2 from the funnel 212, the coal powder falls onto the filter plate 3 and is screened, and the screened coal powder falls into the material receiving groove 221 from the filter hole 31 and the discharge pipe 22 in sequence; when the pulverized coal is added, the driving part 42 is started, the driving shaft rod 41 rotates, and then the filter plate 3 is driven to rotate, so that the pulverized coal and coal blocks falling on the filter plate 3 are subjected to centripetal force to move, the pulverized coal screening effect is relatively better, and the substances retained on the filter plate 3 are relatively less.

The surface of the filter plate 3 close to the cylinder cover 21 is an inclined surface, and the thickness of one end of the filter plate 3 close to the inner wall of the sieving cylinder 2 is gradually reduced to the thickness close to the shaft rod 41, so that the pulverized coal and coal blocks falling onto the filter plate 3 form a trend of rolling towards the shaft rod 41 under the action of gravity, but due to the rotation of the filter plate 3, the pulverized coal and the coal blocks both move towards the cylinder wall of the sieving cylinder 2; in the process, due to the different qualities of the coal blocks and the coal powder, the coal blocks with larger quality are subjected to larger centripetal force and are relatively concentrated at the cylinder wall of the screening cylinder 2, while the coal powder is relatively concentrated in the middle of the filter plate 3, so that the filtering and screening efficiencies are relatively higher, and the screening effect is relatively better.

Referring to fig. 2, a plurality of observation ports 5 are formed in the wall of the screening cylinder 2 in a penetrating manner, a blocking cover 51 which is of an arc plate structure and has the same central axis with the screening cylinder 2 is arranged on the observation ports 5 in a covering manner, and the blocking cover 51 is fixed to the screening cylinder 2 through bolts so as to seal the observation ports 5 and facilitate screening work; and the blocking cover 51 is made of a light-transmitting material so that the screening condition inside the screening cylinder 2 can be observed through the blocking cover 51. After the screening operation is completed, the cap 51 may be removed, and the lump coal remaining on the filter plate 3 may be removed to perform a secondary screening operation.

An object placing plate 6 is arranged on one side of the blocking cover 51 close to the shaft rod 41, one end side of the object placing plate 6 in the length direction is abutted against the plate surface of the filter plate 3, the other end of the object placing plate 6 extends upwards, and the whole object placing plate is inclined and forms an acute angle with a vertical surface; one end in the width direction thereof is fixed to the cap 51, and the other end extends toward the stem 41. In the screening process, because the coal cinder is under the effect of centripetal force, concentrate on the section of thick bamboo wall department of screening section of thick bamboo 2 for the buggy, so the frictional force that gives the coal cinder at filter plate 3 and filter plate 3 are for putting under the effect of thing board 6 pivoted, the coal cinder can be detained on putting thing board 6 to form certain clearance effect to the coal cinder on the filter plate 3, the screening work of the relative longer time of being convenient for, and when taking off blanking cover 51, put the coal cinder on the thing board 6 and can be taken out in the lump, it is relatively more convenient to clear up the coal cinder. Wherein, put thing board 6 and buckle along its length direction, form the arc to the ascending arc board of slope to the probability that the relative increase coal cinder is detained on putting thing board 6.

A plurality of filtering holes 31 are also formed in the object placing plate 6 in a penetrating manner along the thickness direction of the object placing plate so as to screen out the pulverized coal retained on the object placing plate 6 together with the pulverized coal. A baffle 61 is vertically fixed at one end of the object placing plate 6 close to the shaft rod 41 in the width direction, so that the coal blocks retained on the object placing plate 6 are relatively blocked, and the probability that the coal blocks on the object placing plate 6 fall off the filter plate 3 again is relatively reduced.
