Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of screening devices, specifically relating to a screening device for building aggregate production. Background Technology
[0002] Screening devices for building aggregate production are key equipment in aggregate processing production lines. Their core function is to classify crushed materials according to particle size through screens of different specifications, screen out aggregates that meet building standards (such as particle size and gradation), and remove impurities or unqualified particles to ensure the quality of aggregate products.
[0003] In the construction aggregate production process, the screening unit is a major source of dust pollution. When crushed aggregate enters the screening unit, the intense collisions and friction between materials, as well as the high-frequency contact with the screen surface, generate a large amount of fine dust. Since most traditional screening units are not equipped with targeted dust suppression designs, this dust is directly diffused into the surrounding air by the vibration of the screening process.
[0004] This kind of unorganized dust emission not only forms a visible "dust cloud" around the screening equipment, but also spreads with the airflow throughout the entire production area, and even drifts into surrounding residential areas, farmland, or ecological zones. From an environmental perspective, long-term accumulated dust will adhere to plant leaves, hindering plant photosynthesis and causing surrounding greenery to wither; if it settles into the soil, it will change soil structure, reduce soil fertility, and affect crop growth. If the dust spreads into water bodies, it may also cause water turbidity, excessive suspended solids, and disrupt the aquatic ecological balance. Utility Model Content
[0005] The purpose of this invention is to provide a screening device for building aggregate production, aiming to solve the problem that unorganized dust emissions not only form a visible "dust cloud" around the screening device, but also spread with airflow throughout the entire production area, and even drift into surrounding residential areas, farmland, or ecological zones. From an environmental perspective, long-term accumulated dust adheres to plant leaves, hindering photosynthesis and causing surrounding vegetation to wither; when it settles in the soil, it alters soil structure, reduces soil fertility, and affects crop growth. If the dust spreads into water bodies, it can also cause turbidity, excessive suspended solids, and disrupt the aquatic ecological balance.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a screening device for building aggregate production, including a vibrator, a screen installed in the working area of the vibrator, a vibrator installed at the bottom of the vibrator, two supports welded to the surface of the vibrator on one side of the opening, and a crossbar installed between the two supports;
[0007] A set of atomizing nozzles is installed at equal intervals on the surface of the crossbar, and one end of each atomizing nozzle is connected to the water supply soft...
[0008] On the tube, each atomizing nozzle is fixedly mounted on the surface of the crossbar by a clamp. The bottom of the atomizing nozzle is provided with a recycling trough, and the two ends of the recycling trough are respectively welded to the outer wall of the corresponding bracket.
[0009] In order to enable the crossbar to rotate between the two supports, as a screening device for building aggregate production of this utility model, preferably, a first bearing is fixedly fitted on one side of each support, and a round rod is welded in the inner ring of the other side of the first bearing, and the two ends of the crossbar are respectively connected to a round rod.
[0010] In order to make the height of the U-shaped friction block adjustable according to the requirements, as a screening device for building aggregate production of this utility model, preferably, one of the supports is welded to the top of an end plate, and two square bars are movably installed through one side of the end plate, and the two square bars are parallel to each other.
[0011] The bottoms of the two square bars are fixedly connected to one side of the outer wall of the U-shaped friction block.

An adjusting bolt is threaded through the center end of the connecting rod. The bottom of the adjusting bolt is fixedly connected to the inner ring of the second bearing. The other side of the outer ring of the second bearing is fixedly fitted into the inside of the end plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] When the vibratory screener is used to vibrate and screen building aggregates, the water supply hose is connected to an external water supply device. This allows water to flow through the hose to the atomizing nozzle, which then sprays water mist to suppress the dust generated during the vibratory screener's operation, thus reducing environmental harm.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please refer to Figures 1-5. The present invention provides the following technical solution: a screening device for building aggregate production, including a vibrator 1, a screen 2 installed in the working area of the vibrator 1, a vibrator 3 installed at the bottom of the vibrator 1, two supports 4 welded on the surface of the opening side of the vibrator 1, and a crossbar 5 installed between the two supports 4.
[0027] When in use, the building aggregate to be screened is gradually added onto the screen 2. During operation, the vibrator 1 drives the screen 2 to vibrate through the vibrator 3 at the bottom, so that the screen 2 can screen the building aggregate on its surface.
[0028] A set of atomizing nozzles 6 are installed at equal intervals on the surface of the crossbar 5. One end of each atomizing nozzle 6 is connected to the water supply hose 7. Each atomizing nozzle 6 is fixedly installed on the surface of the crossbar 5 by a clamp 8. A recycling trough 9 is provided at the bottom of the atomizing nozzle 6. The two ends of the recycling trough 9 are respectively welded to the outer wall of the corresponding bracket 4.
[0029] Preferably, a first bearing 41 is fixedly fitted on one side of each bracket 4, and a round rod 42 is welded to the inner ring of the other side of the first bearing 41. The two ends of the crossbar 5 are respectively connected to a round rod 42.
[0030] In actual use, when the crossbar 5 is rotated, the crossbar 5 will rotate inside the corresponding first bearing 41 through the round rods 42 on both sides, so that the crossbar 5 can drive the atomizing nozzle 6 to adjust the angle.
[0031] Preferably, an end plate 10 is welded to the top of one of the brackets 4, and two square bars 101 are movably installed through one side of the end plate 10, and the two square bars 101 are parallel to each other.
[0032] The bottoms of the two square bars 101 are fixedly connected to the outer wall of one side of the U-shaped friction block 102. The inside of the U-shaped friction block 102 is fitted onto the outer wall of a round rod 42. The tops of the two square bars 101 are fixedly connected to the bottoms of both ends of the connecting rod 103. An adjusting bolt 104 is threaded through the center end of the connecting rod 103. The bottom of the adjusting bolt 104 is fixedly connected to the inner ring of the second bearing 105. The outer ring of the second bearing 105 is fixedly fitted into the inside of the end plate 10.
[0033] In practical use, the adjusting bolt 104 is rotated counterclockwise, so that the connecting rod 103 will pass through the screw between it and the adjusting bolt 104.
[0034] The textured structure moves upward. When the connecting rod 103 moves upward, it drives the two square bars 101 to move upward, which in turn drives the U-shaped friction block 102 to move upward. Finally, the inner wall of the U-shaped friction block 102 presses against the outer wall of the corresponding round rod 42, thus fixing the round rod 42 and fixing the rotated crossbar 5 at the adjusted angle.
[0035] The U-shaped friction block 102 has a rough outer wall at the contact end with the round rod 42. This generates a huge friction force when the U-shaped friction block 102 contacts the round rod 42, thus ensuring the positioning stability of the crossbar 5.
[0036] Preferably, the recovery tank 9 is installed at an angle between the two brackets 4, and the size of the collection area of the recovery tank 9 is greater than the length of the atomizing nozzle 6.
[0037] When the atomizing nozzle 6 is working, the water droplets produced at its tip will drip into the recovery tank 9 and accumulate inside the recovery tank 9. When the water droplets inside the recovery tank 9 reach a certain level, the operator can drain the accumulated water.
[0038] In practical use, when the vibrating machine 1 is vibrating and screening building aggregates, the water supply hose 7 is connected to an external water supply device. Water then flows through the water supply hose 7 to the atomizing nozzle 6, which sprays water mist to suppress the dust generated by the vibrating machine 1 during operation.
[0039] In addition, during use, the crossbar 5 can rotate between the two brackets 4 via the first bearing 41 and the round rod 42, thereby adjusting the spray angle of the atomizing nozzle 6 to meet a wider range of application needs.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
