The bottom of the crushing device is equipped with a container for holding the crushed material, and the container is equipped with a material inlet and outlet component for material entry and exit.

[0004] Existing construction waste processing equipment generates significant dust during the shredding process, polluting the environment. Furthermore, the equipment only performs shredding, producing waste of varying sizes that hinders further processing. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a device and process for treating construction waste in order to solve the above-mentioned problems, thereby resolving the issues mentioned in the background section.

[0006] To address the above problems, the present invention provides a technical solution:

[0007] A device for processing construction waste includes a housing. Inside the housing, two crushing rollers are mounted via bearings. Each crushing roller has a transmission gear fixedly connected to one end on its outer side, forming a meshing transmission connection. A motor base is fixedly connected to the left outer wall of the housing, and a drive motor is mounted on the upper end of the motor base. The output shaft of the drive motor is fixedly connected to one of the transmission gears. A feed inlet is fixedly connected to the upper end of the housing, and an anti-overflow dust mechanism is provided inside the feed inlet. A sorting port is fixedly connected to the bottom of the housing, and a conical ring is slidably connected to the inner side of the sorting port. A coarse filter cone is fixedly connected to the top of the conical ring, and an inclined block is fixedly connected to the top inner side of the coarse filter cone. Slag discharge ports are provided on both the left and right side walls of the sorting port.

[0008] Preferably, the dust-proof mechanism includes multiple support rods fixedly connected to the inner wall of the feed inlet. A support plate is fixedly connected to all the support rods. A fixing post is fixedly connected to the upper end of the support plate. A plug is slidably sleeved on the outer side of the fixing post and slidably connected to the inner side of the upper opening of the feed inlet. A spring is provided on the inner side of the plug. One end of the spring is fixedly connected to the fixing post, and the other end is fixedly connected to the inner surface of the plug. A protective sleeve is fixedly connected between the support plate and the plug, located on the outer side of the fixing post. A push-pull handle is fixedly connected to the top of the plug. By pushing the plug downward with the push-pull handle, it is separated from the upper opening of the feed inlet. Then, waste is fed into the machine housing through the feed inlet. After releasing the push-pull handle, the spring in the dust-proof mechanism will assist in resetting the plug upward and sealing the feed inlet, thereby preventing the overflow of dust generated during waste crushing.

[0009] Preferably, a flow guide shroud is fixedly connected to the top inner side of the housing, and the flow guide shroud communicates with the feed inlet. The flow guide shroud allows waste to be directed to the crushing roller.

[0010] Preferably, two symmetrically distributed guide posts are fixedly connected to the inner bottom of the sorting port, and the guide posts are slidably connected to the conical ring. A spring is sleeved on the outer side of the main body of each guide post. One end of the spring is fixedly connected to the conical ring, and the other end of the spring is fixedly connected to the inner surface of the sorting port. The guide posts and springs provide auxiliary repositioning for the conical ring and the coarse filter cone.

[0011] Preferably, a baffle is slidably connected to the outer side of the sorting port, and a sliding rod is slidably connected inside the flange of the baffle. One end of the sliding rod is fixedly connected to the machine housing, and the other end of the sliding rod is fixedly connected to a limit block, which abuts against the flange of the baffle. A magnetic block is fixedly connected to the upper section of the sliding rod. The baffle effectively blocks the slag discharge port.

[0012] Preferably, a fine material outlet is slidably connected to the bottom of the sorting port. Multiple fixed rods are fixedly connected to the lower inner side of the fine material outlet, and a motor is mounted on all of these fixed rods. A rotating shaft is fixedly connected to the end of the output shaft of the motor. A shaped rod is fixedly connected to the upper section of the rotating shaft, and the shaped rod abuts against the inclined block. A sieve plate is fixedly connected to the upper inner side of the fine material outlet. The rotating shaft passes through the sieve plate and is rotatably connected to it. A fan blade is fixedly connected to the lower section of the rotating shaft. A brush is fixedly connected to the middle section of the rotating shaft, and the brush abuts against the sieve plate. A non-woven fabric sheet is fixedly connected to the bottom of the fine material outlet. When the motor is energized, it drives the rotating shaft to rotate. The rotating shaft drives the fan blade, brush, and shaped rod to rotate synchronously. The shaped rod rotates on the surface of the inclined block and, in conjunction with a spring, causes the coarse filter cone to vibrate up and down. Simultaneously, the brush sweeps the sieve plate.

[0013] Preferably, an insert block is fixedly connected to the outer side of the fine material outlet, and a fixed sleeve is fixedly connected to the bottom of the sorting port. A locking pin is slidably connected inside the fixed sleeve, and the locking pin is inserted into the insert block. A second spring is provided inside the fixed sleeve, one end of which is fixedly connected to the locking pin, and the other end of which is fixedly connected to the inner surface of the fixed sleeve. A lever is fixedly connected to the end of the locking pin, and the lever passes through the fixed sleeve and is slidably connected to it. By pulling the locking pin laterally with the lever, the locking pin is disengaged from the insert block, thereby releasing the restriction on the fine material outlet.

[0014] A process for treating construction waste includes the following steps:

[0015] Step 1: First, the drive motor is powered on and started, which drives one of the crushing rollers to rotate. The other crushing roller rotates synchronously through the transmission between the gears.

[0016] Step Two: Once the motor is powered on, it drives the rotating shaft to rotate. The rotating shaft drives the fan blades, brushes, and irregularly shaped rods to rotate synchronously. The irregularly shaped rods rotate on the surface of the inclined block and, in conjunction with the spring, cause the coarse filter cone to vibrate up and down. At the same time, the brushes sweep the screen plate.

[0017] Step 3: Push the plug downwards using the push-pull handle to separate it from the upper opening of the feed inlet. Then, feed the waste into the machine housing through the feed inlet. Release the push-pull handle, and the spring in the dust prevention mechanism will help the plug return upwards and seal the feed inlet, thereby preventing the overflow of dust generated during waste crushing and protecting the on-site environment.

[0018] Step 4: After being guided by the flow guide, the waste enters the crushing roller, where it is crushed and falls into the sorting port.

[0019] Step 5: The crushed waste is first filtered by the coarse filter cone. Larger particles of waste will fall into the cone ring, while smaller particles of waste will fall through the mesh of the coarse filter cone and be filtered again by the screen plate. At the same time, the rotation of the fan blades will exhaust the air in the machine casing, and the dust will be filtered through the non-woven fabric sheet before being discharged.

[0020] Step Six: While the coarse filter cone vibrates, it can prevent the mesh of the coarse filter cone from clogging, while the brush sweeps the sieve plate, thereby preventing the mesh of the sieve plate from clogging. This can ensure that the coarse and fine separation process is smooth at the same time.

[0021] Step 7: Finally, pull the gate up so that it engages with the magnetic block, exposing the slag discharge port. The coarse material will then be discharged smoothly. Then, pull the locking pin horizontally with the lever to disengage the locking pin from the insert block, thereby releasing the restriction on the fine material outlet. Then, remove the fine material outlet and take out the fine waste. Finally, tear off the non-woven fabric sheet for cleaning.

[0022] The beneficial effects of this invention are as follows: This invention relates to a device and process for treating construction waste, which features dust prevention, multi-stage screening, and anti-clogging screening. In specific use, it has the following beneficial effects:

[0023] First, by setting up a dust-proof mechanism inside the feed inlet of the device, when it is necessary to put decoration waste into the machine casing for crushing, simply push the plug down with the push-pull handle to separate it from the upper opening of the feed inlet, then put the waste into the machine casing through the feed inlet, and then release the push-pull handle. The spring in the dust-proof mechanism will help the plug return to its original position and seal the feed inlet, thereby preventing the dust generated during the crushing process from overflowing and protecting the on-site environment.

[0024] Secondly, by setting a sorting port at the bottom of the machine casing, and using a sliding conical ring inside the sorting port, with a coarse filter cone at the top of the conical ring, the crushed decoration waste can be initially sorted. Then, a fine material outlet is set below the sorting port, and the screen plate in the fine material outlet can perform secondary sorting, thereby improving the waste sorting effect.

[0025] Finally, by setting an inclined block at the bottom of the coarse filter cone and then setting a rotating shaft driven by an electric motor inside the fine material outlet, and by setting a fan blade, a brush and a special-shaped rod on the rotating shaft, the fan blade, the brush and the special-shaped rod all rotate with the rotating shaft. The special-shaped rod, through its cooperation with the inclined block, causes the coarse filter cone to vibrate up and down, thereby preventing the mesh of the coarse filter cone from clogging. The brush sweeps the screen plate, thereby preventing the mesh of the screen plate from clogging. In this way, the coarse and fine separation process can be ensured at the same time.

A protective sleeve 86 is fixedly connected between the support plate 82 and the plug 84 and located on the outer side of the fixing post 83. A push-pull handle 87 is fixedly connected to the top of the plug 84. Push the plug 84 downward by pushing the handle 87 to separate it from the upper opening of the feed port 7. Then, put the waste into the housing 1 through the feed port 7. Then, release the handle 87. The spring 85 in the dust prevention mechanism 8 will help the plug 84 return to the upper position and seal the feed port 7, thereby preventing the overflow of dust generated during the waste crushing process.

[0038] The sorting port 10 has two symmetrically distributed guide posts 13 fixedly connected to its inner bottom, and the guide posts 13 are slidably connected to the conical ring 11. A spring 14 is sleeved on the outer side of the main body of each guide post 13. One end of the spring 14 is fixedly connected to the conical ring 11, and the other end is fixedly connected to the inner surface of the sorting port 10. The guide posts 13 and spring 14 provide auxiliary repositioning for the conical ring 11 and the coarse filter cone 12.

[0039] The sorting port 10 is slidably connected to a baffle 16 on its outer side. A sliding rod 17 is slidably connected inside the flange of the baffle 16. One end of the sliding rod 17 is fixedly connected to the housing 1, and the other end is fixedly connected to a limiting block 18, which abuts against the flange of the baffle 16. A magnetic block 19 is fixedly connected to the upper section of the sliding rod 17. The baffle 16 effectively blocks the slag discharge port 15.

[0040] The sorting port 10 has a fine material outlet 21 slidably connected to its bottom. Multiple fixed rods 22 are fixedly connected to the lower inner side of the fine material outlet 21, and a motor 23 is shared among these fixed rods 22. A rotating shaft 24 is fixedly connected to the end of the output shaft of the motor 23. A shaped rod 25 is fixedly connected to the upper section of the rotating shaft 24, and the shaped rod 25 abuts against the inclined block 20. A sieve plate 27 is fixedly connected to the upper inner side of the fine material outlet 21. The rotating shaft 24 passes through the sieve plate 27 and is rotatably connected to it. A fan blade 26 is fixedly connected to the lower section of the rotating shaft 24. A brush 28 is fixedly connected to the middle section of the rotating shaft 24, and the brush 28 abuts against the sieve plate 27. A non-woven fabric sheet 29 is fixedly connected to the bottom of the fine material outlet 21. When the motor 23 is powered on, it drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the fan blade 26, brush 28 and shaped rod 25 to rotate synchronously. The shaped rod 25 rotates on the surface of the inclined block 20 and cooperates with the spring 14 to make the coarse filter cone 12 vibrate up and down. At the same time, the brush 28 sweeps the screen plate 27.

[0041] The fine material outlet 21 is fixedly connected to an insert block 30 on its outer side. A fixed sleeve 31 is fixedly connected to the bottom of the sorting port 10. A locking pin 32 is slidably connected inside the fixed sleeve 31, and the locking pin 32 is inserted into the insert block 30. A second spring 33 is provided on the inner side of the fixed sleeve 31.

By pulling the locking pin 32 laterally with the lever 34, the locking pin 32 is disengaged from the insert block 30, thereby releasing the restriction on the fine material outlet 21.

[0042] A process for treating construction waste includes the following steps:

[0043] Step 1: First, the drive motor 6 is powered on and started, which drives one of the crushing rollers 2 to rotate. The other crushing roller 2 rotates synchronously through the transmission between the transmission gears 3.

[0044] Step 2: After the motor 23 is powered on, it drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the fan blade 26, brush 28 and irregular rod 25 to rotate synchronously. The irregular rod 25 rotates on the surface of the inclined block 20 and cooperates with the spring 14 to make the coarse filter cone 12 vibrate up and down. At the same time, the brush 28 sweeps the screen plate 27.

[0045] Step 3: Push the plug 84 downwards using the push-pull handle 87 to separate it from the upper opening of the feed inlet 7. Then, feed the waste into the housing 1 through the feed inlet 7. Then, release the push-pull handle 87. The spring 85 in the dust prevention mechanism 8 will help the plug 84 return to its original position and seal the feed inlet 7, thereby preventing the overflow of dust generated during waste crushing and protecting the on-site environment.

[0046] Step 4: After being guided by the flow guide hood 9, the waste enters the crushing roller 2, is crushed by the crushing roller 2, and falls into the sorting port 10.

[0047] Step 5: The crushed waste is first filtered by the coarse filter cone 12. Larger particles of waste will fall into the cone ring 11, while smaller particles of waste will fall through the mesh of the coarse filter cone 12 and be filtered again by the sieve plate 27. At the same time, the rotation of the fan blade 26 will exhaust the air in the casing 1, and the dust will be discharged after being filtered by the non-woven fabric sheet 29.

[0048] Step 6: While the coarse filter cone 12 vibrates, it can prevent the mesh of the coarse filter cone 12 from clogging, while the brush 28 sweeps the sieve plate 27, thereby preventing the mesh of the sieve plate 27 from clogging. This can ensure that the coarse and fine separation process is smooth at the same time.

[0049] Step 7: Finally, pull up the gate 16 to make it engage with the magnetic block 19, exposing the slag discharge port 15, allowing the coarse material to be discharged smoothly. Then, pull the locking pin 32 horizontally with the lever 34 to disengage the locking pin 32 from the insert block 30, thereby releasing the restriction on the fine material outlet 21. Then, remove the fine material outlet 21 and take out the fine material waste. Finally, tear off the non-woven fabric piece 29 for cleaning.
