Description

Technical Field

[0001] The present invention relates to the technical field of ecological environment restoration, and in particular to a device and method for non-hazardous treatment of hazardous solid waste. Background Art

[0002] Due to the development and utilization of mineral resources, a large amount of solid waste has been left behind. Typical pollution factors in solid waste are pH value, total copper, total zinc, total cadmium, total lead, total chromium, hexavalent chromium, alkyl mercury, total mercury, total beryllium, total barium, total nickel, total silver, total arsenic, total selenium, inorganic fluoride, cyanide, etc.

[0003] Most solid wastes are hazardous. If left untreated, their hazardous factors can be transported into the aquatic environment through rainwater. Furthermore, solid waste can be introduced into the soil through production activities, causing soil pollution. Improper storage can also generate dust and other air pollution caused by wind, harming the ecological environment.

[0004] In the process of treating hazardous solid waste, it is necessary to first determine the composition of the hazardous solid waste and pour the hazardous solid waste into a crusher for crushing. After the crushing is completed, the waste slag needs to be heated so that the lead and zinc in the waste slag at high temperature are decomposed into oxides. The oxides are separated and purified by adding soda ash and pure acid solution, and then the waste slag and valuable elements of lead and zinc can be recycled. When using the existing waste slag dryer, it is usually necessary to manually pour the hazardous solid waste into the feeding funnel. Some hazardous solids will generate dust during the pouring process and will be inhaled by the lungs of the staff, which will pose a threat to the health of the staff and is not conducive to actual promotion and application.

Through the high-speed rotation of the discharge pipe, the blockage of the discharge pipe can be reduced.

[0023] A non-hazardous treatment method for hazardous solid waste, the method comprising the following steps:

[0024] S1: First, the waste slag is crushed, and then the crushed waste slag is placed in the loading hopper. The controller is used to control the loading hopper mouth to tilt slightly upward. After the equipment is equipped, the controller can be used to control the ordinary motor to work, which will drive the reciprocating screw to rotate and the support plate to move upward. During the movement, the connecting rod will be driven to rotate, and the dust cover will be pushed to gradually open.

[0025] S2: When the reciprocating screw is rotating, the second bevel gear on the ordinary motor will also rotate, which will drive the rotation of the first bevel gear, and at the same time drive the rotation of the rotating shaft, and then drive the fan blades to rotate. At the same time, the rotation of the ordinary motor output shaft can also drive the rotation of the first pulley, and through the action of the transmission belt, it will drive the rotation of the second pulley, and at the same time drive the rotation of the rotating tube;

[0026] S3: The rotation of the rotating tube can drive the rotation of the second rotating plate, which in turn can drive the rotation of the dust hopper, thereby increasing the dust collection area of ​​the dust hopper. The piston rod of the second electric telescopic rod pushes the dust hopper and the charging hopper to shorten the distance, thereby reducing the area of ​​flying dust. The fan blades in S2 rotate to suck the flying dust into the dust collection box through the dust hopper for collection.

[0027] S4: When the support plate continues to move upward, the rising loading hopper triggers the pressure sensor on the vertical plate, which in turn transmits the control information to the wireless signal transceiver. The wireless signal transceiver transmits the control information to the controller, and the controller controls the first electric telescopic rod to work. The lifting of the piston rod of the first electric telescopic rod causes the loading hopper to rotate about the rotation center of the first rotating plate, causing the hopper mouth of the loading hopper to gradually tilt downward. At this time, the dust cover has reached the maximum opening angle, and the waste slag in the loading hopper will enter the interior of the waste slag dryer through the feeding funnel;

[0028] S5: Subsequently, the servo motor and the hot air blower are controlled to start, and the conveying auger is driven to rotate, which can stir the waste slag dropped in S4 and continuously scoop it up through the conveying auger, so that the waste slag is spirally advanced, so that the waste slag is fully exposed to the high-temperature hot air. At the same time, the electric valve is controlled to open by the controller, and the lead and zinc in the waste slag under high temperature form oxides, which are then discharged through the electric valve channel. The lead and zinc oxides are collected, and the waste slag is directly discharged from the discharge pipe;

[0029] S6: The waste slag dried in S5 will fall into the dustproof box. When the waste slag falls, a lot of flying dust will be generated. In order to reduce the inhalation of workers, the dustproof box can be used to reduce the dispersion of flying dust. At the same time, the dust suction fan will absorb the falling flying dust. Then, the flying dust is collected by the dust collecting bag. After the slag in the dustproof box is stable, the rotary door on the dustproof box can be opened to collect the heated waste slag.

[0030] S7: Put lead-zinc oxide into a reactor, and pour pure acid or soda ash solution into the reactor and mix them thoroughly. The lead-zinc oxide after the reaction will be separated and purified, and the valuable elements of lead and zinc can be recovered. The collected waste slag can be added with a curing agent to form a solidified material. After grinding in a ball mill, it can be used as a concrete admixture. Without changing the water-cement ratio, part of the mineral powder can be used to replace cement and added to the concrete. Due to the effect of temperature rise, the strength of the concrete will be improved.

[0031] In summary, the present invention includes at least one of the following beneficial effects:

[0032] 1. The present invention controls the ordinary motor to work through the controller, which in turn drives the rotation of the second bevel gear and then drives the fan blades to rotate, which can suck the flying dust into the dust collecting box. At the same time, the rotation of the output shaft of the ordinary motor can also drive the first pulley to rotate, and through the action of the transmission belt, it drives the rotating tube to rotate, and then drives the rotation of the dust collection hopper, thereby increasing the dust collection area of ​​the dust collection hopper, further reducing the possibility of dust being inhaled by the staff, thereby greatly improving the dust collection effect of the fan blades, and through the push of the piston rod of the second electric telescopic rod, it can be pulled closer The distance between the dust hopper and the loading hopper can reduce the area of ​​flying dust, thereby improving the dust collection effect of the fan blades. When the output shaft of the ordinary motor rotates, it can also drive the rotation of the bidirectional screw rod, and then drive the rotation of the connecting rod, which can close the dust cover to prevent the waste slag from being scattered in the waste slag dryer, further reducing the possibility of flying dust being inhaled by the staff. Through the setting of the automatic feeding mechanism, the waste slag can be automatically fed. Compared with traditional manual feeding, it can reduce the possibility of inhaling flying dust during manual feeding, and further improve the safety of the staff.

[0033] 2. The present invention can drive the rotation of the bidirectional screw through the rotation of the output shaft of the ordinary motor, and then drive the operation of the automatic feeding mechanism, and at the same time drive the dust collection mechanism to perform dust collection operations, and also drive the adjustment components in the dust collection mechanism to work, so that the dust collection mechanism and the automatic feeding mechanism can operate at the same time, reducing the use of one motor.

[0034] 3. The present invention can drive the rotation of the conveying auger through the rotation of the output shaft of the servo motor, and at the same time drive the rotation of the driving gear, and then drive the rotation of the driven gear, and drive the rotation of the discharge pipe. Through the high-speed rotation of the discharge pipe, the blockage of the discharge pipe can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] When it is necessary to load the waste slag, the flying dust in the waste slag will appear to be scattered wantonly. The controller controls the ordinary motor 28 to work, so that the output shaft of the ordinary motor 28 can drive the rotation of the reciprocating screw 17, and then drive the support plate 19 and the charging hopper 23 to continue to rise. When the charging hopper 23 triggers the control component, the charging hopper 23 will be controlled to dump. During the dumping process, the support plate 19 will continue to rise, and the continuously rising support plate 19 will not affect the dumping of the charging hopper 23. After the dumping is completed, the charging hopper 23 is reset by controlling the controller. At the same time, the rotation of the output shaft of the ordinary motor 28 can drive the rotation of the second bevel gear 30, which can drive the rotation of the first bevel gear 29, and at the same time can drive the rotation of the rotating shaft 44, and then can drive the fan The blades 13 rotate to suck the flying dust into the dust collecting box 34. At the same time, the rotation of the output shaft of the ordinary motor 28 can also drive the first pulley 31 to rotate. Through the action of the transmission belt 32, the second pulley 35 is driven to rotate, and the rotating tube 36 is driven to rotate, which can drive the rotation of the second rotating plate 37, and then drive the rotation of the dust hopper 40, thereby increasing the dust collection area of ​​the dust hopper 40, further reducing the possibility of dust being inhaled by the staff, thereby greatly improving the dust collection effect of the fan blades 13.

A controller is fixedly installed on the outside of the dustproof box 12, and the first electric telescopic rod 20, the pressure sensor 26 and the wireless signal transceiver 25 are all electrically connected to the controller.

[0052] When the reciprocating screw 17 rotates, it will drive the support plate 19 to move upward, and the rising charging hopper 23 will trigger the pressure sensor 26 on the vertical plate 24, and then transmit the control information to the wireless signal transceiver 25, and the wireless signal transceiver 25 will transmit the control information to the controller, and control the first electric telescopic rod 20 to work through the controller. After the piston rod of the first electric telescopic rod 20 is lifted, the charging hopper 23 will rotate about the rotation center on the first rotating plate 21, so that the bucket mouth of the charging hopper 23 gradually tends to decline. At this time, the dust cover 45 reaches the maximum opening angle, and the waste slag in the charging hopper 23 will enter the interior of the waste slag dryer 2 through the feeding funnel 4.

[0053] like Figure 1 and Figure 2 As shown, the dust collecting assembly includes a dust suction fan 14 fixedly mounted on the outside of the dustproof box 12, the input end of the dust suction fan 14 extends to the inside of the dustproof box 12, and a dust collecting bag 16 is provided on the outside of the output end of the dust suction fan 14, and the bag opening of the dust collecting bag 16 is connected to the outside of the output end of the dust suction fan 14 by a clamp 15.

Through the high-speed rotation of the discharge pipe 7, the blockage of the discharge pipe 7 can be reduced.

[0057] A non-hazardous treatment method for hazardous solid waste, the method comprises the following steps:

[0058] S1: First, the waste slag is crushed, and then the crushed waste slag is placed in the charging hopper 23. The controller controls the hopper 23 to tilt slightly upward. After the equipment is equipped, the controller controls the ordinary motor 28 to work, which drives the reciprocating screw 17 to rotate and drives the support plate 19 to move upward. During the movement, the connecting rod 22 is driven to rotate, which pushes the dust cover 45 to gradually open.

[0059] S2: When the reciprocating screw 17 is rotating, the second bevel gear 30 on the ordinary motor 28 will also rotate, which will drive the rotation of the first bevel gear 29, and at the same time drive the rotation of the rotating shaft 44, and then drive the fan blades 13 to rotate. At the same time, the rotation of the output shaft of the ordinary motor 28 can also drive the rotation of the first pulley 31, and through the action of the transmission belt 32, it will drive the rotation of the second pulley 35, and at the same time drive the rotation of the rotating tube 36;

[0060] S3: The rotation of the rotating tube 36 can drive the rotation of the second rotating plate 37, and then drive the rotation of the dust hopper 40, thereby increasing the dust collection area of ​​the dust hopper 40. The piston rod of the second electric telescopic rod 42 pushes the dust hopper 40 to be closer to the charging hopper 23, thereby reducing the area of ​​flying dust. The rotation of the fan blades 13 in S2 can suck the flying dust into the dust box 34 through the dust hopper 40 for collection.

[0061] S4: When the support plate 19 continues to move upward, the rising loading hopper 23 will trigger the pressure sensor 26 on the vertical plate 24, which will then transmit the control information to the wireless signal transceiver 25. The wireless signal transceiver 25 will in turn transmit the control information to the controller, and the controller will control the first electric telescopic rod 20 to work. After the piston rod of the first electric telescopic rod 20 is lifted, the loading hopper 23 will rotate about the rotation center on the first rotating plate 21, so that the bucket mouth of the loading hopper 23 gradually tends to decline. At this time, the dust cover 45 opens to the maximum angle, and the waste slag in the loading hopper 23 enters the interior of the waste slag dryer 2 through the feeding funnel 4;

[0062] S5: Subsequently, the servo motor 11 and the hot air blower 6 are controlled to start, and the conveying auger 3 is driven to rotate, which can stir the waste slag that falls in S4, and continuously scoop it down through the conveying auger 3, so that the waste slag is presented in a spiral forward manner, so that the waste slag is fully in contact with the high-temperature hot air. At the same time, the controller controls the electric valve 5 to open, and the lead and zinc in the waste slag under high temperature forms oxides, which are then discharged through the channel of the electric valve 5, and the lead and zinc oxides are collected, and the waste slag is directly discharged from the discharge pipe 7;

[0063] S6; The waste slag dried in S5 will fall into the dust box 12. When the waste slag falls, a lot of flying dust will be generated. In order to reduce the inhalation of workers, the dust box 12 can reduce the dispersion of flying dust. At the same time, the dust suction fan 14 will absorb the falling flying dust. Subsequently, the flying dust is collected by the dust bag 16. After the slag in the dust box 12 is stable, the heated waste slag can be collected by opening the rotary door on the dust box 12.

The collected waste slag can be added with a curing agent to form a solidified material. After grinding in a ball mill, it can be used as a concrete admixture. Without changing the water-cement ratio, part of the mineral powder can be used to replace cement and added to the concrete. Due to the effect of temperature rise, the strength of the concrete will be improved.

[0065] Working principle: First, put the crushed waste slag into the charging hopper 23. After it is equipped, the controller can be used to control the ordinary motor 28 to work, which will drive the reciprocating screw 17 to rotate and drive the support plate 19 to move upward. During the movement, the connecting rod 22 will be driven to rotate, which will push the dust cover 45 to gradually open. When the support plate 19 continues to move upward, the rising charging hopper 23 will trigger the pressure sensor 26 on the vertical plate 24, which will transmit the control information to the wireless signal transceiver 25. The wireless signal transceiver 25 will transmit the control information to the controller and control the first electric telescopic rod 20 to work through the lifting of the piston rod of the first electric telescopic rod 20. The charging hopper 23 is rotated at the rotation center on the first rotating plate 21, so that the bucket mouth of the charging hopper 23 gradually tends to decline. At this time, the dust cover 45 reaches the maximum opening angle, and the waste slag in the charging hopper 23 enters the interior of the waste slag dryer 2 through the feeding funnel 4. At this time, the support plate 19 continues to rise, and the continuously rising support plate 19 will not affect the dumping of the charging hopper 23. After the dumping is completed, the charging hopper 23 is reset by the controller, and the rotation of the output shaft of the ordinary motor 28 can drive the rotation of the second bevel gear 30, and then drive the rotation of the first bevel gear 29, and at the same time drive the rotation of the rotating shaft 44, and then drive the fan blade 13 to rotate, so that the flying dust can be sucked into the dust collecting box 34. At the same time, the rotation of the output shaft of the ordinary motor 28 can also drive the first pulley 31 to rotate, and through the action of the transmission belt 32, it will drive the rotation of the second pulley 35, and at the same time drive the rotation of the rotating tube 36, which can drive the rotation of the second rotating plate 37, and then drive the rotation of the dust hopper 40, thereby increasing the dust suction area of ​​the dust hopper 40, further reducing the possibility of dust being inhaled by the staff, thereby greatly improving the dust suction effect of the fan blade 13, and through the push of the piston rod of the second electric telescopic rod 42, the distance between the dust hopper 40 and the loading hopper 23 can be shortened, thereby reducing the area of ​​flying dust, thereby improving the dust suction effect of the fan blade 13, and when the loading is completed, the support plate 19 moves downward, and at the same time can drive the continuous The rotation of the rod 22 can close the dust cover 45 to prevent the waste slag from being scattered in the waste slag dryer 2, further reducing the possibility of flying dust being inhaled by the staff. Subsequently, the servo motor 11 and the hot air blower 6 are controlled to start, and the conveying auger 3 is driven to rotate, which can stir the waste slag and continuously scoop it down through the conveying auger 3, so that the waste slag advances in a spiral manner, so that the waste slag is fully in contact with the high-temperature hot air. At the same time, the controller controls the electric valve 5 to open, and the lead-zinc oxide will be discharged through the channel of the electric valve 5. The falling waste slag will enter the dust box 12, and the dust of the waste slag during unloading will be collected by the dust suction fan 14 and the dust bag 16, and the clamp 15 is used.In order to facilitate the installation and removal of the dustproof cloth.
