Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a device for crushing recycled brick-concrete aggregates for buildings. Background Art

[0002] With the rapid development of urbanization, a large amount of construction waste such as rubble and ruins will be generated in the process of new urban construction and old urban reconstruction. The large amount of construction waste has caused great pressure on environmental protection, and the recyclable resources in the construction waste have also been wasted due to stacking. The reuse of these recycled aggregates from construction waste can effectively protect the environment and save resources.

[0003] In the announcement number CN218167187U, a construction recycled aggregate crushing device for recycled brick production is disclosed, in which the connecting net used for screening can move up and down, and the aggregates falling on the connecting net after being crushed are lifted up, thereby improving the screening effect, and also preventing unqualified aggregates from being left on the connecting net and blocking the connecting net, resulting in a reduction in the screening speed, which is conducive to the normal screening. However, the above patent content is to lift the aggregates, and does not fully consider the dust pollution generated in the process, and does not make anti-accumulation treatment for the crushed aggregates. When the amount of aggregate introduced is too large or too much, the lifting operation cannot fully and thoroughly screen the aggregates. Instead, due to the small-scale shaking and vibration between the aggregates, some of the aggregates are connected and closely contacted, so that the screening effect of the aggregates is further reduced without considering the dust pollution.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 7 As shown, the present invention is a construction recycled brick-concrete aggregate crushing equipment, comprising a crushing shell 1, a servo motor 2 is arranged on the rear surface of the crushing shell 1, a feed port 3 is provided inside the upper surface of the crushing shell 1, a lower slide plate 4 is fixedly connected to the inside of the crushing shell 1 below the feed port 3, a dust flue 5 is fixedly connected to the side of the crushing shell 1, and a vent is provided on the side of the crushing shell 1 at the upper end of the dust flue 5;

[0033] In the embodiment of the present invention, the device is started, and the crushing wheel 6 inside the crushing shell 1 is driven to rotate by the servo motor 2, and the driving motor 11 is controlled to work, so that the material is poured into the device from the feed port 3 for crushing, and then the material is processed by the crushing wheel 6 and screened by the positioning screen plate 9 to improve the material processing effect. At the same time, the dust fan 13 and the positioning screen rod 21 are used to complete the dust processing inside the device and the material accumulation prevention processing, so as to achieve the effect of intermittent self-screening and the effect of suppressing dust diffusion and material accumulation prevention;

[0034] In the embodiment of the present invention, a filter screen 10 is fixedly connected to the inside of the dust flue 5 at one end away from the crushing shell 1, a driving motor 11 is fixedly connected to the inside of the crushing shell 1 at one side of the dust flue 5, a driving shaft 12 is internally connected to the side of the driving motor 11 close to the dust flue 5, a dust fan 13 is fixedly connected to the end of the driving shaft 12 away from the driving motor 11, a driving wheel 14 is fixedly sleeved on the outside of the driving shaft 12, a driven gear 15 is meshedly connected to one side of the driving wheel 14, and a discharge port 16 is plugged into the side of the crushing shell 1 away from the dust flue 5;

[0035] That is, the driving motor 11 is controlled to work, so that the driving motor 11 drives the driving shaft 12 inside the dust flue 5 to rotate, and then the driving shaft 12 drives the dust fan 13 to rotate, so as to achieve the effect of accelerating the air flow inside the dust flue 5, thereby reducing the internal pressure of the upper port of the dust flue 5, and then absorbing and processing the dust inside the crushing shell 1, and at the same time filtering the dust through the filter 10, and discharging the filtered gas, thereby effectively reducing the risk of pollution in the working environment;

[0036] The interior of the crushing shell 1 is located below the lower slide plate 4 and is symmetrically fixedly connected with a crushing wheel 6, and the crushing wheel 6 cooperates with the servo motor 2. The interior of the crushing shell 1 is slidably connected with a guide slider 7, and the interior of the crushing shell 1 is provided with a guide groove that matches the guide slider 7. A return spring 8 is fixedly connected to the upper surface of the guide slider 7, and the end of the return spring 8 away from the guide slider 7 is fixedly connected to the inner wall of the crushing shell 1. A positioning screen plate 9 is fixedly connected to one side of the return spring 8, and the positioning screen plate 9 is located below the crushing wheel 6. The positioning worm 17 drives the upper limiting worm wheel 22 to rotate through the transmission between the gears. As the limiting worm wheel 22 rotates, the limiting worm wheel 22 drives the convex push plates 24 at both ends to rotate synchronously;

[0037] During the rotation of the projection push plate 24, the projection push plate 24 contacts with the guide slider 7 and pushes the guide slider 7, so that the guide slider 7 slides inside the guide groove and squeezes the reset spring 8, thereby causing the positioning screen plate 9 on the guide slider 7 to rise. When the projection push plate 24 is separated from the guide slider 7, due to the influence of the restoring force of the reset spring 8, the guide slider 7 drives the positioning screen plate 9 to move downward, thereby causing the positioning screen plate 9 to move up and down intermittently, so as to realize the lifting and screening of the materials on the positioning screen plate 9, which helps to improve the screening effect of the positioning screen plate 9 on the one hand, and helps to avoid the accumulation of materials affecting the crushing effect of the crushing wheel 6 on the other hand.

A convex push plate 24 is fixedly sleeved at both the front and rear ends of the transmission cylinder 23, and the convex push plate 24 cooperates with the guide slider 7.

[0039] Through the transmission between the gears, the driving wheel 14 drives the driven gear 15 to rotate synchronously during the rotation process, and then the driven gear 15 drives the reciprocating rod 18 to rotate through the positioning worm 17, and the reciprocating rod 18 drives the external horizontal plate 19 to rotate, thereby realizing the reciprocating operation of the horizontal plate 19, and at the same time, the movable slider 20 on the horizontal plate 19 slides inside the crushing shell 1, thereby limiting the horizontal plate 19, as the horizontal plate 19 reciprocates outside the reciprocating rod 18, the horizontal plate 19 drives the positioning screen rod 21 below to spread the crushed material, thereby avoiding excessive accumulation of materials affecting the working efficiency of the positioning screen plate 9.

[0040] Embodiment 3: The present invention also proposes a method for using a construction recycled brick-concrete aggregate crushing device, comprising the following steps:

[0041] Step 1: feeding and crushing process. The specific feeding and crushing process includes: starting the equipment, driving the crushing wheel 6 inside the crushing shell 1 to rotate through the servo motor 2, and controlling the driving motor 11 to work;

[0042] Step 2: Dust ventilation treatment is accompanied by filtering treatment operations to reduce the impact on the working environment. The specific content is: control the driving motor 11 to work, so that the driving motor 11 drives the driving shaft 12 inside the dust flue 5 to rotate, and then the driving shaft 12 drives the dust fan 13 to rotate, so as to achieve the effect of accelerating the air flow inside the dust flue 5, thereby reducing the internal pressure of the upper port of the dust flue 5, and then absorbing the dust inside the crushing shell 1, and at the same time filtering the dust through the filter 10, and discharging the filtered gas, thereby effectively reducing the risk of pollution in the working environment;

[0043] Step 3: The reciprocating stacking process is completed based on the gear transmission principle, and is accompanied by a power-assisted auxiliary effect. The specific content is: through the transmission between the gears, the driving wheel 14 drives the driven gear 15 to rotate synchronously during the rotation, and then the driven gear 15 drives the reciprocating rod 18 to rotate through the positioning worm 17, and the reciprocating rod 18 drives the external horizontal plate 19 to rotate, thereby realizing the reciprocating operation of the horizontal plate 19, and at the same time, the moving slider 20 on the horizontal plate 19 slides inside the crushing shell 1, thereby limiting the horizontal plate 19, and as the horizontal plate 19 reciprocates outside the reciprocating rod 18, the horizontal plate 19 drives the positioning screen rod 21 below to spread the crushed materials, thereby avoiding excessive accumulation of materials affecting the working efficiency of the positioning screen plate 9;

[0044] Step 4: Based on the gear transmission principle and the intermittent vibration screening process completed under the linkage of components to improve the screening effect, the specific content is: through the transmission between the gears, the positioning worm 17 drives the upper limiting worm wheel 22 to rotate, and with the rotation of the limiting worm wheel 22, the limiting worm wheel 22 drives the convex push plates 24 at both ends to rotate synchronously, and in the process of the rotation of the convex push plate 24, it contacts and pushes the guide slider 7, so that the guide slider 7 slides inside the guide groove and squeezes the reset spring 8, thereby causing the positioning screen plate 9 on the guide slider 7 to rise. When the convex push plate 24 separates from the guide slider 7, due to the influence of the restoring force of the reset spring 8, the guide slider 7 drives the positioning screen plate 9 to move downward, and then the positioning screen plate 9 intermittently moves up and down, so as to realize the lifting and screening of the material on the positioning screen plate 9, which helps to improve the screening effect of the positioning screen plate 9 on the one hand, and helps to avoid the accumulation of materials affecting the crushing effect of the crushing wheel 6 on the other hand;

[0045] Step 5: Feeding and processing, specifically: pouring the material from the feed port 3 into the equipment for crushing, and then through the processing of the crushing wheel 6 and the screening of the positioning screen plate 9, to improve the processing effect of the material, and at the same time through the dust fan 13 and the positioning screen rod 21 components to complete the dust treatment inside the equipment and material anti-accumulation treatment, thereby achieving the effect of intermittent self-screening, and can also achieve the effect of suppressing dust diffusion and preventing material accumulation.

[0046] In summary, based on the dust ventilation treatment and accompanied by filtering treatment operations, in order to reduce the impact on the working environment, the driving shaft 12 drives the dust fan 13 to rotate, so as to achieve the effect of accelerating the air flow inside the dust flue 5, thereby reducing the internal pressure of the upper port of the dust flue 5, and then absorbing the dust inside the crushing shell 1, and at the same time filtering the dust through the filter 10, and discharging the filtered gas, thereby effectively reducing the risk of working environment pollution, and based on the gear transmission principle to achieve the reciprocating operation of the horizontal plate 19, so that the horizontal plate 19 drives the positioning screen rod 21 below to spread the crushed material, thereby avoiding excessive accumulation of materials affecting the working efficiency of the positioning screen plate 9, and based on the gear transmission principle and the intermittent vibration screening completed under the linkage of the convex push plate 24 and the guide slider 7, on the one hand, it helps to improve the screening effect of the positioning screen plate 9, and on the other hand, it helps to avoid the accumulation of materials affecting the crushing effect of the crushing wheel 6, which can not only achieve the effect of intermittent self-screening, but also achieve the effect of suppressing dust diffusion and preventing material accumulation.
