Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically a device for removing impurities during concrete processing. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, water, and admixtures in a certain proportion, followed by stirring, molding, and curing. It features high strength, durability, and good plasticity, allowing it to adapt to the shape and load-bearing requirements of different engineering scenarios. As a core material in construction engineering, it is widely used in various infrastructure constructions such as housing, roads, bridges, and water conservancy facilities.

[0003] During concrete processing, cement, sand and gravel aggregates, water, and admixtures are prepared according to the design mix ratio, and impurities are removed. The raw materials are measured and put into the concrete mixer. The mixture is mixed for the specified time. After mixing, it is quickly transported to the construction site by concrete mixer truck or delivery pump. The concrete is poured into the formwork according to the construction specifications. During pouring, it is vibrated to compact it. The concrete is naturally or pressurized to form within the formwork. After reaching the specified strength, the formwork is removed.

[0004] When removing impurities from concrete, metallic impurities and tough materials are mixed together in the aggregate. A single impurity removal method is difficult to completely remove them, and residual impurities can lead to reduced concrete strength or damage to processing equipment.

[0005] Therefore, a concrete processing debris removal device is proposed to address the above problems. Utility Model Content

The electromagnetic filter plate generates magnetic force to adsorb metallic impurities in the aggregate, reducing the impact of metal residue on concrete strength or wear on subsequent processing equipment. The column winding around the tough impurities in the aggregate enables simultaneous removal of various impurities, improving aggregate purity. After power failure, the plug blocks the holes in the electromagnetic filter plate, reducing the passage of metallic and tough impurities through the electromagnetic filter plate and reducing secondary mixing. The vibration generated by the resonant ring is transmitted to the aggregate screen plate, which can shake out blockages in the mesh, reducing the decrease in processing efficiency caused by screen plate blockage and reducing the frequency of unclogging.

[0009] Preferably, a guide hood is fixedly connected to one side of the impurity removal bin; the guide hood is shaped like a truncated pyramid; a connecting air pipe is fixedly connected to one side of the guide hood; the truncated pyramid guide hood, in conjunction with the connecting air pipe, connects to the dust removal device to guide dust in, thereby achieving a dust removal effect. This can reduce the spread of dust to the surrounding environment, reduce the amount of cleaning work, keep the work area clean, and at the same time reduce the amount of dust falling back into the aggregate, thus increasing the stability of concrete product quality.

[0010] Preferably, the support leg is equipped with casters at the bottom; a handle is fixed to one side of the impurity removal bin; by pushing the handle to rotate the casters, the impurity removal bin can be flexibly moved to the mixing equipment, storage bin, or other locations, which can reduce aggregate processing time, improve overall processing efficiency, and increase adaptability to different sites.

[0011] Preferably, a wear-resistant pad is fixed to the inner wall of the impurity removal chamber; the wear-resistant pad is correspondingly arranged to the inner wall of the impurity removal chamber; by setting a wear-resistant pad on the inner wall of the impurity removal chamber, elastic buffering can be used to reduce the direct contact between metal objects in the concrete aggregate and the inner wall of the impurity removal chamber, reduce the wear and deformation of the inner wall of the impurity removal chamber caused by scratching and impact of metal objects, reduce maintenance and replacement costs, and extend the service life of the impurity removal chamber.

[0012] Preferably, the handle surface is fitted with an anti-slip sleeve; the anti-slip sleeve is cylindrical; by fitting an anti-slip sleeve on the handle surface, the friction between the handle and the hand can be increased, the directional accuracy when pushing can be increased, and the risk of equipment collision caused by hand slippage can be reduced.

[0013] The advantages of this utility model are: 1.

[0014] 2. The concrete processing debris removal device of this utility model forms a guide channel between the electromagnetic filter plate and the aggregate screen plate through the inclined plate, so that the falling aggregate slides into the middle of the aggregate screen plate, reducing the uneven screening caused by the aggregate being dispersed and accumulated at the edge of the screen plate, increasing the contact area between the aggregate and the aggregate screen plate, improving screening efficiency and impurity removal rate.

[0018] 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 scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5As shown in the embodiment of this utility model, a concrete processing debris removal device includes a debris removal bin 1; multiple support legs 11 are fixedly connected to the bottom of the debris removal bin 1; an electromagnetic filter plate 12 is fixedly connected to the middle of the debris removal bin 1; the electromagnetic filter plate 12 is inclined; multiple columns 13 are fixedly connected to the top of the electromagnetic filter plate 12; multiple rotating electromagnets 14 are fixedly connected to the bottom of the electromagnetic filter plate 12; the rotating electromagnets 14 are electrically connected to the electromagnetic filter plate 12; a plug 15 is fixedly connected to the end of the rotating electromagnet 14; an aggregate screen plate 16 is slidably connected to the middle of the debris removal bin 1; the aggregate screen plate 16 is arranged below the electromagnetic filter plate 12; the aggregate screen plate 16 is inclined; the aggregate screen plate 16. Spring telescopic rods 17 are fixedly connected to the four corners of the aggregate screen plate 16; the spring telescopic rods 17 are fixedly connected to the impurity removal bin 1; a resonant ring 18 is fixedly connected to the bottom of the aggregate screen plate 16; a vibration generator 19 is fixedly connected to the bottom of the resonant ring 18; a discharge port 110 is fixedly connected to the bottom of the impurity removal bin 1; during operation, the electromagnetic filter plate 12 is connected to the power supply, and the power is turned on, so that the electromagnetic filter plate 12 generates magnetic force. When the current passes through the rotating electromagnet 14, the rotating electromagnet 14 rotates, pulling the plug 15 out of the hole of the electromagnetic filter plate 12. The vibration generator 19 is connected to the power supply, so that it emits sound waves, which are transmitted to the aggregate screen plate 16 through the resonant ring 18, causing the aggregate screen plate 16 to vibrate. The spring telescopic rods 17 absorb the vibration and reduce the vibration. The power is transmitted to the impurity removal bin 1, and concrete aggregate is poured in from the top of the impurity removal bin 1. The aggregate falls through the holes of the electromagnetic filter plate 12 onto the aggregate screen plate 16. Metal substances mixed in the aggregate are adsorbed by the electromagnetic filter plate 12, while the remaining impurities slide down the inclined surface of the electromagnetic filter plate 12 by gravity. Tough impurities in the aggregate come into contact with the column 13 as they slide down and become entangled on the surface. The aggregate screen plate 16 uses vibration to accelerate the separation of aggregate and impurities, reducing accumulation on the surface of the aggregate screen plate 16. At the same time, it shakes out impurities from the mesh of the aggregate screen plate 16, which then slide down the surface of the aggregate screen plate 16. The concrete aggregate flows out from the discharge port 110 and is collected. After the impurity removal is completed, the power is turned off, the electromagnetic filter plate 12 loses its magnetism, and the rotating electric... Magnet 14 is reset, blocking the holes on the surface of electromagnetic filter plate 12. Metal impurities on the surface of electromagnetic filter plate 12 slide off and are attracted by the magnetic force generated by electromagnetic filter plate 12, reducing the impact of metal residue on concrete strength or wear of subsequent processing equipment. Column 13 wraps around tough impurities in the aggregate to achieve simultaneous removal of various impurities and improve aggregate purity. After power is cut off, hole plug 15 blocks the holes of electromagnetic filter plate 12, which can reduce the passage of metal and tough impurities through electromagnetic filter plate 12 and reduce secondary mixing. The vibration generated by resonant ring 18 is transmitted to aggregate screen plate 16, which can shake out the blockage impurities in the mesh, reduce the decrease in processing efficiency caused by screen plate blockage, and reduce the frequency of unclogging.

[0021] like Figures 3 to 5As shown, a set of inclined plates 2 are fixedly connected to the middle of the impurity removal bin 1; the inclined plates 2 are arranged between the electromagnetic filter plate 12 and the aggregate screen plate 16; the inclined plates 2 are arranged in a triangular shape; a set of vertical plates 21 are fixedly connected to the top of the aggregate screen plate 16; the vertical plates 21 are arranged inside the spring telescopic rod 17; during operation, when concrete aggregate falls from the electromagnetic filter plate 12, the contact surface with the inclined plates 2 slides down to the middle of the aggregate screen plate 16. When the aggregate screen plate 16 vibrates, the impurities will move from the middle of the aggregate screen plate 16 to the surrounding area. The vertical plates 21 intercept the impurities moving to the aggregate screen plate 16 and the impurity removal bin. At the gap of 1, the inclined plate 2 forms a guide channel between the electromagnetic filter plate 12 and the aggregate screen plate 16, so that the falling aggregates can be concentrated and slide to the middle of the aggregate screen plate 16, reducing the uneven screening caused by the aggregates being dispersed and accumulated at the edge of the screen plate, increasing the contact area between the aggregates and the aggregate screen plate 16, improving screening efficiency and impurity removal rate. The vertical plate 21 is set around the inner side of the aggregate screen plate 16 to form an edge barrier, which can intercept the debris moving towards the edge of the aggregate screen plate 16 during vibration, reduce the debris stuck between the aggregate screen plate 16 and the impurity removal bin 1, increase the stability of equipment operation, and reduce the risk of failure.

[0022] like Figures 1 to 2 As shown, a guide cover 3 is fixedly connected to one side of the impurity removal bin 1; the guide cover 3 is arranged in the shape of a truncated quadrangular pyramid; a connecting air pipe 31 is fixedly connected to one side of the guide cover 3; during operation, the connecting air pipe 31 is connected to the dust removal device, and the dust removal device is turned on to suck the dust generated during the screening process from the guide cover 3. The truncated quadrangular pyramid guide cover 3 cooperates with the connecting air pipe 31 to connect with the dust removal device, guiding the dust in, achieving the dust removal effect, which can reduce the spread of dust to the surrounding environment, reduce the amount of cleaning work, keep the working area clean, and at the same time reduce the dust falling back into the aggregate, increasing the stability of concrete product quality.

[0023] like Figures 1 to 3 As shown, the bottom of the support leg 11 is equipped with casters 4; a handle 41 is fixed to one side of the impurity removal bin 1; during operation, pushing the handle 41 causes the casters 4 to move the impurity removal bin 1, reducing the concrete aggregate transfer steps. By pushing the handle 41 to rotate the casters 4, the impurity removal bin 1 can be flexibly moved to the mixing equipment, storage bin, etc., which can reduce the aggregate processing and transfer time, improve the overall processing efficiency, and increase the adaptability to different sites.

[0024] like Figures 1 to 3As shown, a wear-resistant pad 5 is fixedly connected to the inner wall of the impurity removal chamber 1; the wear-resistant pad 5 is correspondingly arranged to the inner wall of the impurity removal chamber 1; during operation, when concrete aggregate is put into the impurity removal chamber 1, the wear-resistant pad 5 uses its elasticity to reduce the scraping between the metal objects in the concrete aggregate and the inner wall of the impurity removal chamber 1. By setting the wear-resistant pad 5 on the inner wall of the impurity removal chamber 1, the elastic buffer can be used to reduce the direct contact between the metal objects in the concrete aggregate and the inner wall of the impurity removal chamber 1, reduce the wear and deformation of the inner wall of the impurity removal chamber 1 caused by the scratching and impact of metal objects, reduce maintenance and replacement costs, and extend the service life of the impurity removal chamber 1.

[0025] like Figures 1 to 2 As shown, the surface of the handle 41 is fitted with an anti-slip sleeve 6; the anti-slip sleeve 6 is cylindrical; during operation, the anti-slip sleeve 6 increases the friction between the handle 41 and the hand, reducing hand slippage. At the same time, the cylindrical shape fits the inner wall of the palm. By fitting the anti-slip sleeve 6 on the surface of the handle 41, the friction between the handle 41 and the hand can be increased, the directional accuracy when pushing can be increased, and the risk of equipment collision caused by hand slippage can be reduced.

[0026] Working principle: By connecting the electromagnetic filter plate 12 to the power supply and turning on the power, the electromagnetic filter plate 12 generates magnetic force. When current passes through the rotating electromagnet 14, the rotating electromagnet 14 rotates, pulling the plug 15 out of the hole in the electromagnetic filter plate 12. The vibration generator 19 is then connected to the power supply, causing it to emit sound waves. These sound waves are transmitted through the resonant ring 18 to the aggregate screen plate 16, causing the aggregate screen plate 16 to vibrate. The spring telescopic rod 17 absorbs the vibration, reducing its transmission to the impurity removal bin 1, allowing the concrete aggregate to be poured from the top of the impurity removal bin 1. As aggregate enters, it passes through the holes of the electromagnetic filter plate 12 and falls onto the aggregate screen plate 16. Metallic substances mixed in the aggregate are adsorbed by the electromagnetic filter plate 12, while other impurities slide down the inclined surface of the electromagnetic filter plate 12 due to gravity. Tough impurities within the aggregate contact the column 13 as they slide down and become entangled on its surface. The aggregate screen plate 16 uses vibration to accelerate the separation of aggregate and impurities, reducing their accumulation on its surface. Simultaneously, it shakes out impurities from the mesh of the aggregate screen plate 16, which then slide down its surface. The concrete aggregate then exits from the discharge point. The impurities flow out of the collection port 110. After impurity removal is completed, the power is disconnected, the electromagnetic filter plate 12 loses its magnetism, and the electromagnet 14 is rotated to reset it, blocking the holes on the surface of the electromagnetic filter plate 12. The metallic impurities on the surface of the electromagnetic filter plate 12 slide off the surface of the electromagnetic filter plate 12. When the concrete aggregate falls from the electromagnetic filter plate 12, it slides off the contact surface with the inclined plate 2 to the middle of the aggregate screen plate 16. When the aggregate screen plate 16 vibrates, the impurities will move from the middle of the aggregate screen plate 16 to the surrounding areas. The vertical plate 21 intercepts the impurities moving to the aggregate screen plate 16. At the gap between the impurity removal bin 1 and the air pipe 31, the dust removal device is connected. The dust removal device is turned on to suck the dust generated during the screening process from the guide cover 3. Push the handle 41 to make the caster 4 move the impurity removal bin 1, reducing the concrete aggregate transfer steps. When the concrete aggregate is put into the impurity removal bin 1, the wear-resistant pad 5 uses elasticity to reduce the scraping of metal objects in the concrete aggregate with the inner wall of the impurity removal bin 1. The anti-slip sleeve 6 increases the friction between the handle 41 and the hand, reducing hand slippage, and at the same time, the cylindrical shape fits the inner wall of the palm.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
