Description

Technical Field

[0001] This invention relates to the field of waste collection technology, and in particular to an automatic waste collection and recycling device for a closed, dust-proof production line. Background Technology

[0002] Currently, in the production processes of industries such as machining, injection molding, wood processing, food and pharmaceuticals, a large amount of waste and dust are inevitably generated. If these wastes are not collected and treated in a timely and effective manner, it will not only cause waste of raw materials and increase the production costs of enterprises, but also cause dust to spread in the workshop, pollute the working environment, endanger the health of operators, and may even cause safety accidents such as dust explosions.

[0003] In existing technologies, the common waste collection method on production lines mainly involves operators periodically using brooms, shovels, and other tools to clean up waste and transport it to designated locations. This method is labor-intensive, inefficient, and prone to secondary dust dispersion during the cleaning process, making it difficult to meet the requirements of modern factories for clean production and occupational health protection. Furthermore, some production lines are equipped with industrial vacuum cleaners or central vacuum systems that use negative pressure to suck waste into collection containers. However, in practical applications, these devices are mostly open or semi-open structures, which can easily cause dust to leak from the collection containers or pipe interfaces during waste collection and cleaning, failing to achieve true airtight dust prevention. Therefore, they have the drawback of being inconvenient for waste dust prevention collection and cannot meet customer needs.

[0004] Therefore, those skilled in the art have provided a closed, dustproof, automatic waste collection and recycling device for production lines to solve the problems mentioned in the background art. Summary of the Invention

[0014] Optionally, a rubber pad is fixedly connected to the bottom of the base plate, and the rubber pad is rectangular.

[0015] By adopting the above technical solution, the rubber pad can be conveniently used to protect the bottom of the base plate.

[0016] Optionally, handles are fixedly connected to both the left and right sides of the front of the waste box, and the handles are concave.

[0028] In this embodiment: By setting up a base plate 1, a recycling bin 2, a collection funnel 3, and a waste frame 4, the present invention can achieve convenient collection and centralized storage of production waste. By setting up a dust extraction hood 5, a filter screen 6, a water tank 11, a perforated pipe 12, and a negative pressure fan 131, an efficient dust extraction and sealed dust prevention system can be constructed, effectively suppressing dust overflow. By setting up an ultrasonic sensor 7, a dust sensor 8, a PLC controller 9, a relay 10, and an audible and visual alarm 15, an intelligent monitoring and early warning network can be formed to realize real-time monitoring and automatic alarm of the material level and dust concentration in the recycling bin 2. By setting up the above structure, it is convenient to collect and use waste in a dust-proof manner, thereby meeting the needs of customers.

[0029] Example 2: Reference Figure 2 and Figure 3The filter assembly 14 includes a convex cylinder 141, the bottom of which is connected to the water tank 11, activated carbon 142 is placed in the inner cavity of the convex cylinder 141, and a filter cover 143 is threadedly connected to the top of the convex cylinder 141.

[0030] In this embodiment: By providing a convex cylinder 141, activated carbon 142 and filter cover 143, the present invention can conveniently filter harmful gases.

[0031] The implementation principle of this invention is as follows: During use, the operator first checks that the waste frame 4 is correctly placed at the bottom of the inner cavity of the recycling bin 2, aligned with the outlet of the collection funnel 3. They then check that an appropriate amount of clean water has been injected into the water tank 11, ensuring the water level submerges the perforated pipe 12. They confirm that the activated carbon 142 has been installed into the convex cylinder 141 and that the filter cover 143 is tightened. Finally, they check that the ultrasonic sensor 7, dust sensor 8, PLC controller 9, relay 10, and audible and visual alarm 15 are powered on normally. After completing the above checks, the operator activates the PLC controller 9 via relay 10. Start the negative pressure fan 131. After the negative pressure fan 131 starts, it draws air from the recycling box 2 through the suction pipe 132, so that the inside of the recycling box 2 is in a negative pressure state. Under the action of negative pressure, the waste and dust generated by the production line are sucked into the inner cavity of the recycling box 2 along with the outside air from the collection funnel 3. After the dust-laden airflow enters the recycling box 2, the airflow speed drops sharply because the cross-sectional area of ​​the box is much larger than the cross-section of the pipe. The larger waste particles settle directly from the airflow under the action of gravity and fall into the waste frame 4 at the bottom of the recycling box 2, realizing the primary separation of large particle waste. Fine dust particles that are not settled by gravity continue to move towards the dust hood 5 with the airflow. When the airflow passes through the filter screen 6 embedded on the right side of the dust hood 5, the remaining medium-sized particles are intercepted by the filter screen 6, preventing them from entering the negative pressure fan 131 and the perforated tube 12 at the rear end, thus protecting the equipment. The fine dust particles that pass through the filter screen 6 are drawn into the negative pressure fan 131 through the suction pipe 132 under the suction action of the negative pressure fan 131, and then sent into the perforated tube 12 located at the bottom of the water tank 11 through the exhaust pipe 133. The dust-laden gas is dispersed into tiny bubbles through the evenly opened through holes on the perforated tube 12. During the upward process, the gas fully contacts the water in the water tank 11, and the fine dust particles are captured by the water and settle at the bottom of the water tank 11, completing the secondary water bath purification. After being purified by the water bath, the gas rises to the space above the water tank 11 and then enters the convex cylinder 141 connected to the top of the water tank 11. When the gas passes through the activated carbon 142 placed in the inner cavity of the convex cylinder 141, the residual odor, volatile organic compounds and harmful components are physically adsorbed by the activated carbon 142, achieving three-stage deep purification. The purified clean gas is finally discharged into the atmosphere from the filter cover 143 at the top of the convex cylinder 141, ensuring that the exhaust gas is clean and odorless, and meets the environmental protection emission requirements. During the operation of the device, the ultrasonic sensor 7 detects the height of the waste accumulation in the waste box 4 in real time, and the dust sensor 8 detects the dust concentration in the recycling bin 2 in real time. When the height of the waste accumulation in the waste box 4 reaches the full load threshold set by the ultrasonic sensor 7, the ultrasonic sensor 7 sends a full load signal to the PLC controller 9. The PLC controller 9 triggers the audible and visual alarm 15 through the relay 10 to issue an audible and visual alarm, prompting the staff to clean the waste box 4 in time. When the dust concentration in the recycling bin 2 rises abnormally due to reasons such as seal failure, filter 6 damage, or pipe detachment, the dust sensor 8 sends an abnormal signal to the PLC controller 9. The PLC controller 9 also triggers the audible and visual alarm 15 through the relay 10 to remind the staff to stop the machine and check the sealing. When the audible and visual alarm 15 sounds a full-load alarm, the operator first shuts down the negative pressure fan 131 via the PLC controller 9 and relay 10. After the pressure inside and outside the recycling box 2 is balanced, the operator opens the front door of the recycling box 2 and pulls the waste frame 4 out along the sliding track using the handle 16. The waste collected in the waste frame 4 is transferred to a designated recycling point or subjected to subsequent pre-processing such as crushing or compression. After cleaning, the waste frame 4 is pushed back to its original position, the door is closed, and the negative pressure fan 131 is restarted. The device resumes normal operation. The water tank 11 is filled with water due to the water bath. Wastewater accumulated during dust removal can be periodically discharged through the drain pipe at the bottom left side of water tank 11. Unscrew the pipe cover to discharge the wastewater to the designated treatment facility. After discharge, tighten the pipe cover and refill with clean water through the convex cylinder 141. Before refilling with water, remove the activated carbon 142. When the activated carbon 142 reaches saturation, unscrew the filter cover 143, remove the old activated carbon 142, install new activated carbon 142, and tighten the filter cover 143 to restore the filtration function. This device is simple to operate and facilitates the collection and use of waste for dust prevention, thus meeting the needs of customers.

[0032] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
