Description

Technical Field

[0001] The present application relates to a dispersing device, in particular to a powder dispersing device, and belongs to the field of fracturing proppants. Background Art

[0002] Oil fracturing proppant is made of bauxite, potassium feldspar and manganese ore, and is made by powder granulation and sintering. Various powder raw materials are processed into granules by a granulator. Before granulation, the raw materials need to be screened and mixed evenly to prevent large particles such as stones from being easily mixed into the raw materials, resulting in uneven mixing of the raw materials, resulting in some ungranulated powders mixed in the finished product, resulting in the problem of poor quality of the finished product. The existing screening process is still generally completed by vibrating screening. The defect of this solution is that the raw material is powder, and the powder is in a piled state when stored in the discharge storage bin, which leads to the discharge of the material being easy to agglomerate when screening, resulting in large particles in the powder agglomerate being difficult to be screened out, or the agglomerated powder is screened out as "large particles", thereby affecting the screening effect.

[0038] The top of the material collection bin 1 is provided with a feed inlet, and the side of the material collection bin 1 facing the primary disperser 2 is provided with a discharge port;

[0039] The primary disperser 2 is tilted, the upward end of the primary disperser 2 is connected to the output end of the collecting bin, and the downward end of the primary disperser 2 is located directly above the distributor 3. The primary disperser 2 is in the shape of a duck's foot as a whole, and the primary disperser 2 performs the first dispersion of the powder flowing out of the collecting bin 1;

[0040] The top of the distributor 3 is open, and a plurality of discharge holes are respectively arranged at the bottom of the distributor 3 and at the side of the bottom facing away from the collecting bin 1, and a secondary disperser is arranged below the distributor 3;

[0041] A plurality of the discharge holes are evenly arranged along the extension direction of the distributor 3, and the distributor 3 distributes the powder in the distributor 3 to the secondary disperser through the discharge holes;

[0042] The secondary disperser is arranged horizontally, and the feed end of the secondary disperser is located directly below the distributor 3, and the downstream equipment (screening device) is located directly below the secondary disperser. The secondary disperser performs a third dispersion on the powder.

[0043] Furthermore, the primary disperser 2 includes a first transmission plate and a plurality of first material distribution partitions arranged on the top of the first transmission plate;

[0044] The first transmission plate is arranged obliquely, and an upward end of the first transmission plate is connected to one side of the discharge port;

[0045] A plurality of the first material dividing baffles are arranged at intervals along the horizontal direction of the first transmission plate, forming a plurality of independent dispersion areas 7 on the top of the first transmission plate, and the bottom of the first material dividing baffles is connected to the first transmission plate;

[0046] The dispersion zone 7 of each unit is conical, and the cross-section of the dispersion zone 7 of each unit increases successively in the direction away from the aggregation bin 1, so that after the powder in the aggregation bin 1 enters each dispersion zone 7, the area where the powder is spread from the feed end to the discharge end of the dispersion zone 7 becomes larger and larger, and the first dispersion of the powder is carried out.

[0047] The first transmission plate is an isosceles trapezoidal plate, wherein the upper bottom of the trapezoidal plate faces the material collecting bin 1, and the lower bottom faces the distributor 3;

[0048] The two ends of the first material dividing partition face the aggregate bin 1 and the distributor 3 respectively, and the first material dividing partition is radially arranged around one side of the discharge port of the aggregate bin 1. Specifically, the area formed by two adjacent first material dividing partitions is similar to a cone structure, wherein the smaller end of the cone structure faces the aggregate bin 1, and the larger end faces the distributor 3, thereby forming a structure similar to a duck's foot.

[0049] One side of the first material dividing partition is fixedly connected to the top of the first transmission plate, and both sides of the first material dividing partition are arranged upward. The first material dividing partition is inserted into the discharge port of the aggregate bin 1 at one end toward the aggregate bin 1, and is respectively connected to the aggregate bin 1; the first material dividing plate inserted into the aggregate bin 1 divides the discharge port of the aggregate bin 1 into sub-discharge ports 8 corresponding to the dispersion zones 7 one by one, and the powder in the aggregate bin 1 is diverted at each sub-discharge port 8, and then flows into each dispersion zone 7 respectively. Since the cross-sectional area of ​​each dispersion zone 7 increases successively from the feed end (one end toward the aggregate bin 1) to the discharge end (one end toward the distributor 3), the material entering each dispersion zone 7, from the feed end to the discharge end, the area formed by the material spreading on each first transmission plate of each dispersion zone 7 becomes larger and larger, that is, the spreading area becomes larger and larger, thereby realizing the first dispersion of the powder.

[0050] Furthermore, the length of the secondary disperser is greater than the width of the end of the first transmission plate facing away from the material collecting bin 1 .

[0051] Furthermore, the first material dividing partition plate divides the discharge port into a plurality of independent sub-discharge ports 8 at one end facing the material collecting bin 1, and the sub-discharge ports 8 are arranged corresponding to the dispersion area 7;

[0052] The feed end of the dispersion zone 7 matches the sub-discharge port 8 , and the feed end of the dispersion zone 7 is communicated with the sub-discharge port 8 .

[0053] Furthermore, the cross-section of the secondary disperser is an inverted triangle structure.

[0054] Further, the secondary disperser includes a second transmission plate and a second material distribution partition plate arranged on the top of the second transmission plate;

[0055] The second material dividing baffles are arranged at intervals along the horizontal direction of the second transmission plate, the second material dividing baffles are arranged parallel to each other, and a plurality of the second material dividing baffles arranged at intervals form a plurality of separate transmission cavities 6 above the second transmission plate;

[0056] The feed end of the unit transmission cavity 6 is located below the discharge hole, and the powder of the distributor 3 flows out from the discharge hole into each unit transmission cavity 6, and then flows from the feed end of the transmission cavity 6 to the discharge end of the transmission cavity 6, and finally enters the next-level processing equipment.

[0057] The secondary disperser is located as a whole below the distributor 3, the feed end of the secondary disperser faces the distributor 3, and the discharge end of the secondary disperser faces the lower equipment, which is a screening device in the present application; the width of the secondary disperser is greater than the width of the distributor 3;

[0058] In the present application, the second transmission plate is a rectangular plate, and the width of the rectangular plate is greater than the width of the distributor 3;

[0059] One end of the second material dividing partition is located below the distributor 3, and the other end of the second material dividing partition is arranged away from the distributor 3 and is located above the input end of the screening device;

[0060] One side of the second material distribution partition is fixedly connected to the top of the second transmission plate, and the other end of the second material distribution partition is arranged upward, so as to form a plurality of independent transmission cavities 6 on the top of the second transmission plate; a baffle 14 is arranged at one end of the second material distribution partition facing the distributor 3, wherein the length of the baffle 14 is the same as the width of the second transmission plate, the baffle 14 is located on the side of the distributor 3 away from the lower equipment, and the baffle 14 is fixedly connected to the top of the second transmission plate to prevent the powder flowing into the secondary disperser from being shaken off on the ground;

[0061] A plurality of discharge holes are arranged near the bottom of the distributor 3 on one side facing the lower equipment (the output end of the secondary disperser), and the discharge holes are correspondingly located in each transmission cavity 6, that is, one transmission cavity 6 corresponds to one or more discharge holes;

[0062] Since the discharge end of the primary disperser 2 is located directly above the distributor 3, and the distributor 3 is open, the powder enters the distributor 3 after the primary disperser 2 completes the first dispersion, and then flows out from the discharge holes of the distributor 3 for the second dispersion. After the second dispersion is completed, the fractions fall from the discharge holes onto the secondary disperser. Since the second transmission plate of the secondary disperser is provided with uniform filter holes 15, the fractions falling on the secondary disperser pass through the filter holes 15 for the third dispersion.

[0063] The lower-level equipment is located below the secondary disperser. After the third dispersion, the powder flows out from the filter hole 15 of the secondary disperser and enters the next-level processing equipment for the subsequent screening process.

[0068] In the present application, a first vibration motor 12 is installed on the outer side of the bottom of the first transmission bottom plate of the first-stage disperser 2, and a second vibration motor 13 is installed on the outer side of one end of the bottom of the second-stage disperser facing the collecting bin. By arranging the first vibration motor 12 and the second vibration motor 13, the powder can be further dispersed sufficiently by vibration while avoiding blockage of each discharge port, discharge hole and filter hole.
