Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to an integrated device for high-efficiency screening and dust removal of building aggregates. Background Technology

[0002] Nowadays, construction waste (concrete) can be crushed into aggregates by crushing equipment for secondary use, thereby improving material utilization and reducing material costs while ensuring environmental protection.

[0003] The aggregates from crushed construction waste are uneven in size and need to be screened for secondary use as needed. For example, coarse aggregates can replace natural crushed stone in the preparation of new concrete, and fine aggregates can replace sand in masonry mortar or plastering mortar. However, a large amount of dust is generated during screening, which causes environmental pollution and affects health. Spraying water to suppress dust will affect the material ratio for subsequent secondary use. Utility Model Content

[0004] The purpose of this invention is to provide an integrated device for efficient screening and dust removal of building aggregates, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated device for high-efficiency screening and dust removal of building aggregates, including a support frame;

[0006] A screening assembly includes a dust cover, a frame fixedly connected to the bottom of the dust cover, a screen fixedly connected to the inner wall of the frame, an extension plate fixedly connected to one side of the frame, and fixing blocks fixedly connected to both sides of the bottom of the frame.

[0007] The vibration assembly includes a drive motor, one side of which is fixedly connected to one side of a fixed block. A transmission rod is fixedly connected to the output shaft end of the drive motor. The transmission rod is movably connected through the fixed block. A cam is fixedly sleeved on the side surface of the transmission rod. Through the screen and the cam, the cam rotates under the action of the drive motor, thereby continuously striking the screen and causing the screen to vibrate. This causes the aggregate to disperse quickly, and under the action of vibration, the adhering substances on the aggregate particles are detached. The aggregate is then screened according to size through the screen holes. Larger particles are discharged through the top of the screen via an extension plate, while smaller particles pass through the screen holes and are guided to the other side by the extension plate, thereby effectively screening the aggregate size.

[0008] The negative pressure assembly includes a support frame, with an air pump fixedly connected to the top of the support frame. The input end of the air pump is fixedly connected to the other end of a connecting pipe, which is connected to the air pump. The air pump creates negative pressure inside the dust cover, causing free dust generated during the screening process to be transported to a dust collection bag under the negative pressure, thereby avoiding air pollution, improving the quality of the working environment, and reducing the harm of dust to the human body.

[0009] Preferably, the support is internally fitted with a feeding trough, the bottom of the feeding trough is fixedly connected to a conduit, the support legs of the support are respectively fixedly connected to a fixed column on opposite sides, and the other end of the fixed column is fixedly connected to a feeding trough.

[0010] Preferably, the bottom of the conduit is fixedly connected to the top of the dust cover, the conduit is in communication with the dust cover, and a discharge port for discharging material is provided on one side of the dust cover.

[0011] Preferably, there are multiple cams arranged in a linear array along the extension direction of the transmission rod. Through the screening component, vibration component and negative pressure component, the size of the aggregate and free dust are screened and separated, thereby ensuring effective screening while avoiding environmental pollution and collecting the dust separately, thus improving the screening efficiency and the fineness of the screening.

[0012] Preferably, the plurality of cams rotate with the output shaft of the drive motor via a transmission rod, and the end of the cam away from the transmission rod rotates with the transmission rod and abuts against the bottom of the screen.

[0013] Preferably, a dust collection bag is attached to the output end of the air pump, and the dust cover generates negative pressure and adsorbs dust as the air pump operates.

[0014] Preferably, the screen is used to screen aggregate particles of different sizes, the extension plate is used to guide the larger aggregate particles at the top of the screen, and the screen holes on the screen are for smaller aggregate particles to pass through.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this integrated device for high-efficiency screening and dust removal of building aggregates...

[0016] By creating negative pressure inside the dust cover using an air pump, the free dust generated during the screening process is transported to the dust collection bag under the negative pressure, thereby avoiding air pollution, improving the quality of the working environment, and reducing the harm of dust to the human body.

[0017] The cam, driven by a motor, rotates and continuously strikes the screen, causing it to vibrate. This disperses the aggregate quickly and removes any adhering material from the aggregate particles. The aggregate is then sieved according to size through the screen openings. Larger particles are discharged through the top of the screen via an extension plate, while smaller particles pass through the screen openings and are guided to the other side by the extension plate, thus effectively sieving the aggregate by size.

[0018] The aggregate is screened and separated by screening, vibration and negative pressure components. This ensures effective screening while avoiding environmental pollution and allows for separate collection of dust, thereby improving screening efficiency and fineness. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] This utility model embodiment provides an integrated device for high-efficiency screening and dust removal of building aggregates, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes bracket 1;

[0026] Screening assembly 2 includes a dust cover 201, a frame 203 fixedly connected to the bottom of the dust cover 201, a screen 204 fixedly connected to the inner wall of the frame 203, an extension plate 205 fixedly connected to one side of the frame 203, and fixing blocks 206 fixedly connected to both sides of the bottom of the frame 203 respectively.

[0027] Vibration assembly 3 includes a drive motor 301. One side of the drive motor 301 is fixedly connected to one side of a fixed block 206. The output shaft end of the drive motor 301 is fixedly connected to a transmission rod 302. The transmission rod 302 passes through the fixed block 206 and is movably connected. A cam 303 is fixedly sleeved on the side surface of the transmission rod 302.

[0028] The negative pressure component 4 includes a support frame 401. An air pump 402 is fixedly connected to the top of the support frame 401. The input end of the air pump 402 is fixedly connected to the other end of a connecting pipe 202, which is connected to the air pump 402. In use, a dust collection bag is first attached to the output end of the air pump 402 to collect dust. Then, the air pump 402 and drive motor 301 are started. Subsequently, the crushed aggregate is fed into the feeding trough 5. The aggregate falls onto the screen 204 by gravity through the guide pipe 6. As the drive motor 301 drives the transmission rod 302 and cam 303 to rotate, the ends of the cams 303 at multiple angles strike the screen 204, causing the screen 204 to vibrate continuously, thereby rapidly dispersing the aggregate. Larger particles in the material cannot pass through the screen holes on the screen 204. Under the vibration of the screen 204, they are discharged through the discharge port at the bottom of the dust cover 201 along the inclined screen 204 and the extension plate 205. Smaller particles pass through the screen holes as the screen 204 vibrates and fall into the feed chute 8. They are then guided along the inclined feed chute 8 to the side away from the extension plate 205. During the screening process of the screen 204, the dust in the aggregate is also released. The dust cover 201 prevents the dust from escaping, and the air pump 402 creates negative pressure in the dust cover 201, causing the dust to be transported to the dust collection bag by the air pump 402. This prevents the dust from escaping and causing air pollution. After screening, the dust collection bag can be removed for cleaning.

[0029] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a feeding trough 5 is fixedly sleeved inside the bracket 1, and a conduit 6 is fixedly connected to the bottom of the feeding trough 5. Fixed columns 7 are fixedly connected to the opposite side of the support legs of the bracket 1, and a feeding trough 8 is fixedly connected to the other end of the fixed column 7.

[0030] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the conduit 6 is fixedly connected to the top of the dust cover 201, the conduit 6 is connected to the dust cover 201, and a discharge port for discharging material is provided on one side of the dust cover 201.

[0031] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, there are multiple cams 303 arranged in a linear array along the extension direction of the transmission rod 302. A negative pressure is created inside the dust cover 201 by the air pump 402, causing free dust generated during the screening process to be transported to the dust collection bag under this negative pressure, thus avoiding air pollution, improving the quality of the working environment, and reducing the harm of dust to the human body. Through the screen 204 and the cams 303, the cams 303 rotate under the action of the drive motor 301, continuously striking the screen 204, causing the screen to vibrate. This rapidly disperses the aggregate, and the vibration further disperses the adhering aggregate. The adhering substances on the aggregate particles are removed, and the aggregate is screened according to size through the sieve holes on the screen 204. Larger particles are discharged through the top of the screen 204 and guided by the extension plate 205, while smaller particles pass through the sieve holes on the screen 204 and are guided to the other side by the extension plate 205, thereby effectively screening the aggregate size. Through the screening component 2, the vibration component 3 and the negative pressure component 4, the size of the aggregate and the free dust are screened and separated respectively, thereby ensuring effective screening while avoiding environmental pollution, and collecting the dust separately, thereby improving the screening efficiency and the fineness of the screening.

[0032] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple cams 303 rotate with the output shaft end of the drive motor 301 via the transmission rod 302. The end of the cam 303 away from the transmission rod 302 rotates with the transmission rod 302 and abuts against the bottom of the screen 204.

[0033] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a dust collection bag is attached to the output end of the air pump 402, and the dust cover 201 generates negative pressure and adsorbs dust as the air pump 402 operates.

[0034] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the screen 204 is used to screen aggregate particles of different sizes, the extension plate 205 is used to guide the larger aggregate particles at the top of the screen 204, and the screen holes on the screen 204 are for smaller aggregate particles to pass through.

[0035] Working Principle: In operation, firstly, a dust collection bag is attached to the output end of the air pump 402 to collect dust. Then, the air pump 402 and drive motor 301 are started. Subsequently, the crushed aggregate is fed into the feeding trough 5. The aggregate falls onto the screen 204 by gravity through the guide pipe 6. As the drive motor 301 drives the transmission rod 302 and cam 303 to rotate, the ends of the cams 303 at different angles strike the screen 204, causing the screen 204 to vibrate continuously. This rapidly disperses the aggregate, preventing larger particles from passing through the screen holes. Under the vibration of the screen 204, the aggregate is dispersed along the inclined plane. The inclined screen 204 and the extension plate 205 are discharged through the discharge port at the bottom of the dust cover 201. Smaller particles pass through the screen holes as the screen 204 vibrates and fall into the feed chute 8. They are then guided along the inclined feed chute 8 to the side away from the extension plate 205. During the screening process of the screen 204, the dust in the aggregate is also released. The dust cover 201 prevents the dust from escaping, and the air pump 402 creates negative pressure in the dust cover 201, so that the dust is transported to the dust collection bag by the air pump 402 with the air flow, thereby avoiding the dust from escaping and causing air pollution. After screening, the dust collection bag can be removed for cleaning.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
