Description

Technical Field

[0001] The utility model belongs to the technical field of aggregate production, and particularly relates to an aggregate dust screening device. Background Technique

[0002] As an important material for infrastructure construction such as buildings, roads, bridges, water conservancy, and hydropower, the quality of coarse aggregate is directly related to the stability and durability of engineering projects. In practical applications, the particle shape, quality, and gradation of coarse aggregate have a significant impact on the strength and performance of concrete. Therefore, precise screening of aggregate is an important link to ensure project quality.

[0003] However, the existing aggregate dust screening devices have many deficiencies in screening effect and use convenience. First of all, traditional devices generally use filter screens for screening, but this method is prone to blockage, and with the increasingly strict requirements of the project for the size of aggregate, this single screening method can no longer meet the use requirements under different construction conditions; secondly, it is not convenient to take out the screened aggregate and dust.

[0004] Therefore, it is very necessary to invent an aggregate dust screening device. Content of the Utility Model

[0005] The purpose of the utility model is to provide an aggregate dust screening device to solve the problems mentioned in the background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is an aggregate dust screening device, which includes a box body, a temporary storage box, a screening frame, a limiting frame, a transfer box, a support frame, and a feed pipe. The box body is placed on the ground, and several temporary storage boxes are movably placed inside the box body. A screening frame is arranged on the upper side of the temporary storage box, and the screening frame is fixed inside the box body; several limiting frames are rotatably installed on the outer side surface of the box body through support bearings, and the other end of the limiting frame is arranged in contact with the temporary storage box; a transfer box is arranged on the upper side of the box body, one end of the transfer box is fixed to the box body by bolts, and a support frame is fixed between the other end of the transfer box and the box body by bolts; a feed pipe is fixed to the upper side surface of the transfer box by bolts.

[0008] Furthermore, the temporary storage box includes an outer box, moving wheels, a handle, and an inner box. Several moving wheels are fixed to the lower side surface of the outer box by bolts, and a handle is fixed to one side surface of the outer box by bolts; the inner box is slidably installed inside the outer box, and the inner box is arranged under the screening frame; the outer side surface of the outer box is arranged in contact with one end of the limiting frame. Such a setting facilitates the taking out of the screened aggregate and dust.

[0009] Furthermore, the screening rack includes a mounting plate, a first motor, a gear set, and screening columns. The mounting plate is fixed to the outer side of the box body by bolts, and the first motor is fixed to the upper side of the mounting plate by bolts. The output end of the first motor is fixed to the input end of the gear set, and the output ends of the gear set are respectively fixed to several screening columns. The outer sides of both ends of the screening column are rotatably connected to the box body through support bearings, and the shape of the screening column is conical, and the screening columns face the same direction. Such a setting can screen the aggregate and dust and store the aggregates with different diameters in different temporary storage boxes.

[0010] Furthermore, the transfer box includes a housing, a guide pipe, a rotating column, and an impeller. A guide pipe is fixed to the lower side of one end of the housing by bolts, and the other end of the guide pipe is fixed to the box body by bolts. A support frame is fixed between the other end of the housing and the box body by bolts, and a feed pipe is fixed to the upper end of the housing by bolts. The rotating column is rotatably installed inside the guide pipe through a support bearing, and one end of the rotating column is fixed to the output end of the second motor, and the second motor is fixed to the outer side of the guide pipe by bolts. An impeller is fixed to the outer side of the rotating column by bolts, and the outermost edge of the impeller is in contact with the inner wall of the guide pipe. Such a setting can control the speed at which the aggregate and dust fall onto the screening rack.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. With the setting of the temporary storage box in the utility model, during use, the aggregate and dust screened by the screening rack will fall into the inner box under the action of their own gravity. When the inner box is full of aggregate and dust, the limiting frame can be rotated to disengage the limiting frame from the outer box, and then the handle is pulled to make the temporary storage box slide out inside the box body through the moving wheels. At this time, the staff can slide out the inner box inside the outer box, so as to facilitate the removal of the screened aggregate and dust.

[0013] 2. With the setting of the screening rack in the utility model, through the cooperation of the first motor and the gear set, the screening columns can rotate simultaneously. Among them, due to the conical design of the screening columns, aggregates and dust with different diameters will be separated under the action of the rotational force and fall into different temporary storage boxes according to the size, thus realizing the efficient screening of the aggregate and dust. At the same time, since the screening columns are always in a rotating state, the possibility of blockage can be reduced. Description of the Drawings

[0023] Please refer to Figure 1As shown in the figure, the utility model relates to an aggregate dust screening device, which includes a box body 1, a temporary storage box 2, a screening rack 3, a limiting rack 4, a transfer box 5, a support frame 6 and a feed pipe 7. The box body 1 is placed on the ground, and several temporary storage boxes 2 are movably placed inside the box body 1. A screening rack 3 is arranged on the upper side of the temporary storage box 2, and the screening rack 3 is fixed inside the box body 1; several limiting racks 4 are rotatably installed on the outer side surface of the box body 1 through support bearings, and the other end of the limiting rack 4 is attached to the temporary storage box 2; a transfer box 5 is arranged on the upper side of the box body 1, one end of the transfer box 5 is fixed to the box body 1 by bolts, and a support frame 6 is fixed between the other end of the transfer box 5 and the box body 1 by bolts; a feed pipe 7 is fixed to the upper side surface of the transfer box 5 by bolts.

[0024] As Figure 2 shown, the temporary storage box 2 includes an outer box 21, moving wheels 22, a handle 23 and an inner box 24. Several moving wheels 22 are fixed to the lower side surface of the outer box 21 by bolts, and a handle 23 is fixed to one side surface of the outer box 21 by bolts; an inner box 24 is slidably installed inside the outer box 21, and the inner box 24 is arranged under the screening rack 3; the outer side surface of the outer box 21 is attached to one end of the limiting rack 4. When in use, the aggregate and dust screened out by the screening rack 3 will fall into the inner box 24 under the action of its own gravity. After the aggregate and dust inside the inner box 24 are stored full, the limiting rack 4 can be rotated to make the limiting rack 4 separate from the outer box 21, and then the handle 23 is pulled to make the temporary storage box 2 slide out inside the box body 1 through the moving wheels 22. At this time, the staff can slide out the inner box 24 inside the outer box 21, so as to facilitate the removal of the screened aggregate and dust.

[0025] As Figure 3 shown, the screening rack 3 includes a mounting plate 31, a first motor 32, a gear set 33 and screening columns 34. The mounting plate 31 is fixed to the outer side surface of the box body 1 by bolts, and a first motor 32 is fixed to the upper side surface of the mounting plate 31 by bolts; the output end of the first motor 32 is fixed to the input end of the gear set 33, and the output ends of the gear set 33 are respectively fixed to several screening columns 34; both outer side surfaces of the two ends of the screening column 34 are rotatably connected to the box body 1 through support bearings, and the shape of the screening column 34 is conical. The screening columns 34 face the same direction. When in use, the first motor 32 and the gear set 33 can be used in cooperation to drive several screening columns 34 to rotate simultaneously. At this time, the aggregate and dust sliding down from the transfer box 5 will fall onto the screening columns 34, and then the aggregate and dust will move along the screening columns 34. Among them, because the shape of the screening column 34 is conical, aggregates and dust with different diameters will fall into different temporary storage boxes 2, so as to screen the aggregate and dust.

[0026] As Figure 4As shown, the transfer box 5 includes a shell 51, a material guide pipe 52, a rotating column 53 and an impeller 54.

The outer side of the rotating column 53 is fixed with an impeller 54 by bolts, wherein the outermost edge of the impeller 54 is in contact with the inner wall of the material guide pipe 52. When in use, the aggregate and dust entering through the feed pipe 7 will be temporarily stored inside the outer shell 51, and then enter into the box body 1 through the material guide pipe 52. When the aggregate and dust pass through the material guide pipe 52, the second motor can drive the impeller 54 to rotate through the rotating column 53, thereby controlling the sliding speed of the aggregate and dust inside the material guide pipe 52.

[0027] See also Figures 1-4 As shown, the utility model is an aggregate dust screening device, and its working principle is: when in use, firstly, the aggregate is poured into the transfer box 5 through the feed pipe 7, and then the aggregate will slide along the transfer box 5 to the screening rack 3, and then under the action of the screening rack 3, the aggregate is screened, so that aggregates of different diameters fall into different temporary storage boxes 2, and when the temporary storage box 2 is full, the limit frame 4 can be manually rotated to separate the limit frame 4 from the temporary storage box 2, and then the temporary storage box 2 is taken out from the box body 1, so as to facilitate the removal of the screened aggregates.
