Description

Technical Field

[0001] The present invention belongs to the technical field of construction waste treatment, and in particular relates to an environmentally friendly construction waste treatment device and a method of using the same. Background Art

[0002] Construction waste is the slag, abandoned soil, discarded materials, and other waste generated by construction companies or individuals during the construction and demolition of various buildings, structures, and pipeline networks. With the development of urbanization, the amount of construction waste generated by housing construction is increasing. Most construction waste is directly dumped in the open air or landfilled, which not only consumes land resources but also creates dust and other problems, which can cause serious environmental pollution. Furthermore, long-term storage and landfilling of construction waste can seep into the soil, polluting it and groundwater.

[0003] To this end, it is necessary to recycle construction waste. The existing methods of recycling construction waste are classification or crushing for reuse. For example, the Chinese invention patent with publication number CN108816324A discloses a construction waste crushing device, which can crush construction waste through the mutual cooperation of a crushing mechanism, a driving mechanism, a machine body, a metal discharging mechanism, an adsorption mechanism, a waste discharging mechanism, a leakage port, a mounting plate, a separation mechanism and a walking mechanism. At the same time, it can also separate the metal in the construction waste, which can meet the user's demand for construction waste treatment to a certain extent.

[0004] However, when the device is in use, its feed hopper lacks a dust blocking device, which causes the dust generated when the construction waste is crushed to easily overflow through the feed hopper, thereby easily polluting the air environment and causing harm to the health of workers working nearby. There are certain disadvantages in its use.

[0005] Therefore, in response to the above technical problems, it is necessary to provide an environmentally friendly construction waste treatment device and a method for using the same. Summary of the Invention

[0006] The object of the present invention is to provide an environmentally friendly construction waste treatment device and a method of using the same, so as to solve the problem that dust easily overflows when the construction waste is crushed.

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by one embodiment of the present invention is as follows:

[0008] An environmentally friendly construction waste treatment device comprises a crushing device body, an anti-overflow mechanism and a shielding mechanism;

[0009] The crushing device body is provided with a feed hopper;

[0010] The overflow prevention mechanism is installed on the feed hopper, and the overflow prevention mechanism includes a circulation pump. A pair of opposite side walls of the feed hopper are respectively connected to a positive pressure pipe and a negative pressure pipe, and the positive pressure pipe and the negative pressure pipe are connected to a number of evenly distributed high-pressure nozzles. The other end of the high-pressure nozzle is arranged in the feed hopper, the positive pressure pipe is connected to the air outlet end of the circulation pump, and a return pipe is connected between the negative pressure pipe and the air inlet end of the circulation pump, and a purification box is installed on the return pipe;

[0011] The shielding mechanism is installed on the feed hopper, and the shielding mechanism includes a winding box, a rotating shaft is provided in the winding box, and one end of the rotating shaft located outside the winding box is connected to a motor, a winding roller is connected to the rotating shaft, a pair of linkage ropes are wound around the winding roller, and a shielding curtain is connected to the linkage rope. A pulling mechanism is installed on the feed hopper, and the pulling mechanism corresponds to the shielding curtain.

[0012] Furthermore, a pair of inner walls opposite to each other in the feed hopper are provided with a avoidance groove 1, and the high-pressure nozzle and the shielding curtain are both arranged in the avoidance groove 1. The avoidance groove 1 is used to accommodate the high-pressure nozzle to avoid damage to the high-pressure nozzle by the input construction waste, thereby ensuring the safety of the high-pressure nozzle; the avoidance groove 1 is also used to accommodate the shielding curtain to guide the expansion and storage of the shielding curtain, so that the shielding curtain can completely cover the feed hopper port, avoid dust overflow, and thus avoid environmental pollution.

[0013] Furthermore, the inner wall of the feed hopper is provided with a second avoidance groove for accommodating the drying nozzle;

[0014] A drying pipe is provided in the feed hopper, a branch pipe is connected between the drying pipe and the gas outlet of the circulation pump, a control valve is installed on the branch pipe, and a plurality of evenly distributed drying nozzles are connected to the drying pipe, one end of the drying nozzle is arranged in the second avoidance groove. When the control valve is opened, part of the gas generated by the circulation pump enters the drying pipe through the branch pipe and is sprayed through the plurality of drying nozzles;

[0015] When the heating wire is running, it can heat the gas flowing in the branch pipe, so that the temperature of the gas sprayed by the drying nozzle increases. When the black curtain is rolled up, it can be dried by the gas sprayed by the drying nozzle, thereby preventing the black curtain from being damp and preventing a large amount of dust from adhering to the black curtain.

[0016] Furthermore, the branch pipe is made of heat-conducting metal, and a heating wire is provided on the outside of the branch pipe. The heating wire can instantly heat the gas flowing in the branch pipe, so that the gas flowing in the branch pipe can be quickly heated.

[0017] Furthermore, the pulling mechanism includes a pair of winding boxes 2, the winding boxes 2 are used to reel in or release the linkage rope 2;

[0018] A linkage shaft is connected between the pair of winding boxes so that the pair of winding boxes can rotate synchronously. A linkage rope is wound inside the winding box, and the linkage rope is connected to the blackout curtain. The winding box can pull or release the blackout curtain through the linkage rope.

[0019] One of the winding boxes 2 is connected to a second motor, which is used to drive the winding box 2 to operate, and then to wind or release the linkage rope 2, so that the blackout curtain can be unfolded or rolled up.

[0020] Furthermore, a coating box is provided on one side of the winding box for accommodating a coating tube. A coating tube is provided in the coating box and is arranged on the lower side of the shielding curtain. A plurality of coating nozzles are connected to the coating tube for applying the coating liquid to the shielding curtain. The coating liquid can absorb the dust rising in the feed hopper, thereby preventing dust from overflowing and polluting the environment.

[0021] Furthermore, a liquid storage box is provided at the lower side of the coating box, and a coating pump and coating liquid are provided in the liquid storage box. The coating pump is arranged in the coating liquid, and a delivery pipe is connected between the coating pump and the coating pipe. The coating pump extracts the coating liquid and delivers the coating liquid to the coating pipe.

[0022] Furthermore, the shielding curtain is provided with a plurality of through holes, and the coating liquid adheres to the lower side of the shielding curtain and covers the through holes. The through holes are used for the flow of the cleaning liquid, thereby cleaning the coating liquid on the shielding curtain and also cleaning the dust adhered by the coating liquid, thereby achieving the effect of cleaning the shielding curtain. At the same time, the provision of the through holes can also quickly dry the shielding curtain, thereby increasing the drying efficiency of the shielding curtain and preventing the shielding curtain from being damp and breeding bacteria.

[0023] Both ends of the shielding curtain are connected to a mounting plate, and a sensing chip is provided in the mounting plate for sensing and starting the coating pump so as to coat the coating liquid on the shielding curtain.

[0024] Furthermore, a cleaning mechanism is installed on the main body of the crushing device, which is used to clean the shielding curtain and quickly settle the dust in the feed hopper that is not absorbed by the coating liquid;

[0025] The cleaning mechanism includes a cleaning box, which is provided with a cleaning liquid and a cleaning pump. A pair of opposite side walls of the feed hopper are connected with cleaning pipes, a connecting pipe is connected between the pair of cleaning pipes, and a number of evenly distributed cleaning nozzles are connected to the cleaning pipes. The cleaning nozzles are arranged in the avoidance groove and between the high-pressure nozzle and the shielding curtain. By setting up a pair of cleaning pipes, the cleaning effect of the shielding curtain can be greatly improved, and the sedimentation effect of the dust in the feed hopper can also be greatly improved.

[0026] A method for using the environmentally friendly construction waste treatment device comprises the following steps:

[0027] S1. Add construction waste into the crushing device through the feed hopper and control the operation of the crushing device;

[0028] S2. When the main body of the crushing device is running, the circulation pump is turned on synchronously. The circulation pump delivers gas to the positive pressure pipe. The gas is sprayed from the high-pressure nozzle of the positive pressure pipe to the high-pressure nozzle of the negative pressure pipe, thereby forming an air curtain at the opening of the feed hopper to block dust.

[0029] S3. The gas entering the negative pressure pipe is transported through the return pipe, filtered through the purification box, and finally reused by the circulation pump;

[0030] S4. Controlling the operation of motor 1 and motor 2, motor 2 drives one of the winding boxes 2 to operate. The rotating winding box 2 drives the other winding box 2 to operate synchronously through the linkage shaft. The operation of winding box 2 can wind linkage rope 2. Motor 1 drives the rotating shaft and winding roller to rotate. The winding roller releases linkage rope 1, which in turn pulls the shielding curtain to unfold and cover the opening of the feed hopper. The unfolded shielding curtain is arranged on the lower side of the air curtain to reduce the pressure of the air curtain blocking dust;

[0031] S5. During the unfolding of the shielding curtain, when the first sensing chip is sensed, the coating pump starts to operate, extracts the coating liquid, and delivers it to the coating pipe through the delivery pipe. The coating liquid in the coating pipe is sprayed toward the shielding curtain through the coating nozzle, so that the coating liquid adheres to the lower side of the shielding curtain and covers the through-hole. When the second sensing chip is sensed, the coating pump stops, and the coating liquid on the shielding curtain can be used to adhere to the dust rising in the feed hopper;

[0032] S6. When the construction waste is crushed, the cleaning pump is turned on to extract the cleaning liquid and transport it to the cleaning pipe. The cleaning liquid in the cleaning pipe is sprayed into the feed hopper through the cleaning nozzle. The air curtain can prevent the cleaning liquid from overflowing to avoid wasting the cleaning liquid. The cleaning liquid will clean the coating liquid on the shielding curtain through the through hole, and at the same time, it will also clean the dust adhered to the coating liquid, so that the dust falls into the feed hopper;

[0033] S7, continuously running the cleaning pump, the cleaning fluid can clean the shade curtain;

[0034] S8. After cleaning is completed, the cleaning pump is turned off, the heating wire is controlled to operate, and the control valve is opened. Part of the gas generated by the circulation pump enters the drying tube through the branch pipe and is ejected through the drying nozzle. The heating wire can heat the gas ejected from the drying nozzle, thereby increasing the temperature of the gas ejected from the drying nozzle.

[0035] S9. Control the operation of motor 1 and motor 2, the winding roller winds the linkage rope 1 and the shade curtain, and the winding box 2 releases the linkage rope 2. At this time, the sensing chip will not be sensed, and when the shade curtain passes through the gas sprayed by the drying nozzle, the sprayed gas can dry the wet shade curtain until the shade curtain is completely rolled up on the winding roller, and then turn off the circulation pump, motor 1 and motor 2.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] The present invention can effectively prevent the dust generated during the crushing of construction waste from overflowing through the setting of corresponding mechanisms, thereby preventing the air environment from being polluted. At the same time, it can also create a good working environment for staff working nearby and protect the health of staff to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The present invention will be described in detail below with reference to the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0052] The present invention discloses an environmentally friendly construction waste treatment device. Figures 1-11 As shown, it includes a crushing device body 1, an anti-overflow mechanism 2, a shielding mechanism 3, and a cleaning mechanism 4.

[0053] Among them, a feed hopper 101 is provided on the crushing device main body 1, which is convenient for adding construction waste into the crushing device main body 1 so that the crushing device main body 1 can be used to crush the construction waste.

[0054] Preferably, the crushing device body 1 and the feed hopper 101 used in this application are both existing technologies, so their working principles are not described in detail.

[0055] In addition, a pair of inner walls opposite to each other in the feed hopper 101 are provided with a relief groove 102, i.e. Figure 1In the position shown, both the high-pressure nozzle 203 and the shielding curtain 306 are located within the avoidance groove 102. The avoidance groove 102 accommodates the high-pressure nozzle 203, preventing damage to the nozzle 203 by incoming construction waste and ensuring its safety. Furthermore, the avoidance groove 102 also accommodates the shielding curtain 306, guiding its deployment and retraction, ensuring that it completely covers the port of the feed hopper 101, preventing dust from escaping and, consequently, environmental pollution.

[0056] Specifically, the inner wall of the feed hopper 101 is provided with a second avoidance groove 103, and the second avoidance groove 103 is provided on the side wall of the feed hopper 101 perpendicular to the avoidance groove 102, that is, Figure 6 In the position shown, the avoidance groove 203 is used to accommodate the drying nozzle 208 so that the drying nozzle 208 can be used to spray high-temperature gas to dry the shielding curtain 306 and prevent the shielding curtain 306 from getting wet.

[0057] Preferably, when the shielding curtain 306 is rolled up, the shielding curtain 306 can block the second avoidance groove 103 to prevent construction waste from entering the second avoidance groove 103.

[0058] refer to Figures 1-11 As shown, the anti-overflow mechanism 2 is installed on the feed hopper 101. The anti-overflow mechanism 2 is used to form an air curtain at the opening of the feed hopper 101 to prevent dust from overflowing from the feed hopper 101 when the crushing device body 1 crushes construction waste, thereby preventing dust from polluting the environment and creating a good working environment for the staff.

[0059] Among them, the overflow prevention mechanism 2 includes a circulation pump 201, and a pair of opposite side walls of the feed hopper 101 are respectively connected to a positive pressure pipe and a negative pressure pipe 202, and the positive pressure pipe and the negative pressure pipe 202 are connected to a number of evenly distributed high-pressure nozzles 203. The other end of the high-pressure nozzle 203 is arranged in the feed hopper 101, the positive pressure pipe is connected to the air outlet end of the circulation pump 201, and a return pipe 204 is connected between the negative pressure pipe 202 and the air inlet end of the circulation pump 201.

[0060] Preferably, the lengths of the positive pressure pipe and the negative pressure pipe 202 are both greater than the opening length of the feed hopper 101 to ensure the formation effect of the air curtain.

[0061] When the circulation pump 201 is running, the high-pressure gas generated by the circulation pump 201 enters the positive-pressure pipe and is sprayed to the high-pressure nozzle 203 on the negative-pressure pipe 202 through the high-pressure nozzle 203 on the positive-pressure pipe, thereby forming an air curtain at the opening of the feed hopper 101. The air curtain is used to block the dust in the feed hopper 101 and prevent the dust from overflowing.

[0062] The gas entering the negative pressure pipe 202 is transported through the return pipe 204 , and the return gas can be filtered by the purification box 205 to prevent the return gas from containing dust, thereby preventing the dust from damaging the circulation pump 201 .

[0063] In addition, a purification box 205 is installed on the return pipe 204. The purification box 205 is used to filter the return gas to prevent the return gas from containing dust.

[0064] Preferably, the purification box 205 includes a box body, and three filter screens are provided in the box body. The mesh ratio of the three filter screens is 1:2:3, which are used for graded filtration of the reflux gas, thereby greatly improving the overall filtering effect.

[0065] Specifically, a drying pipe 206 is provided in the feed hopper 101, and a branch pipe 207 is connected between the drying pipe 206 and the outlet end of the circulation pump 201. A control valve is installed on the branch pipe 207. When the control valve is opened, part of the gas generated by the circulation pump 201 will enter the branch pipe 207.

[0066] Furthermore, a number of evenly distributed drying nozzles 208 are connected to the drying pipe 206, one end of which is located in the second avoidance groove 103. When the control valve is opened, some of the gas generated by the circulation pump 201 enters the drying pipe 206 through the branch pipe 207 and is sprayed by the drying nozzles 208.

[0067] Furthermore, the branch pipe 207 is made of a heat-conducting metal material, and a heating wire 209 is provided on the outside of the branch pipe 207. A protective sleeve is provided on the outside of the heating wire 209. The heating wire 209 can instantly heat the gas flowing in the branch pipe 207, so that the gas flowing in the branch pipe 207 can be heated quickly.

[0068] When the heating wire 209 is in operation, it heats the gas flowing through the branch pipe 207, thereby increasing the temperature of the gas ejected from the drying nozzle 208. When the shielding curtain 306 is reeled in, the gas ejected from the drying nozzle 208 dries it, thereby preventing the shielding curtain 306 from becoming damp and from collecting dust.

[0069] refer to Figures 1-11 As shown, the shielding mechanism 3 is installed on the feed hopper 101. The shielding mechanism 3 is used to form a barrier layer on the lower side of the air curtain, which can greatly reduce the pressure of the air curtain and the purification box 205, and at the same time avoid dust overflow, and also has a good dust treatment effect.

[0070] The shielding mechanism 3 includes a winding box 301. A rotating shaft 302 is disposed within the winding box 301. One end of the rotating shaft 302, located outside the winding box 301, is connected to a motor 303. A winding roller 304 is connected to the rotating shaft 302. The motor 303 drives the rotating shaft 302 and winding roller 304 to rotate, thereby retracting and releasing the linkage rope 305 and the shielding curtain 306.

[0071] In addition, a pair of linkage ropes 305 are wound around the winding roller 304, and the linkage ropes 305 are connected to the shielding curtain 306. The winding roller 304 can pull the shielding curtain 306 through the linkage ropes 305, thereby realizing the reeling of the shielding curtain 306.

[0072] When the shielding curtain 306 is unfolded, the shielding curtain 306 can completely cover the port of the feed hopper 101, that is, Figure 1 The state shown can prevent the dust in the feed hopper 101 from overflowing, and at the same time can greatly reduce the pressure of the air curtain, avoid the air curtain containing too much dust, reduce the frequency of replacing and cleaning the linkage rope 305, and reduce the burden on the staff.

[0073] Preferably, the shielding curtain 306 is graphene fiber, which has the advantages of high strength and good elasticity. At the same time, it also has the advantages of heat storage and warmth preservation, light absorption and heat generation, waterproofness, antibacterial and antibacterial, moisture absorption and moisture conduction, and anti-static. The cleaning liquid can pass through the shielding curtain 306 smoothly and separate the coating liquid 314. It is dried by the high-temperature gas sprayed by the drying nozzle 208, which has a better drying effect and will not breed bacteria.

[0074] Specifically, the shielding curtain 306 is provided with a plurality of through holes 3061, and the coating liquid 314 adheres to the underside of the shielding curtain 306 and covers the through holes 3061. The through holes 3061 allow the flow of cleaning liquid, thereby cleaning the coating liquid 314 on the shielding curtain 306 and also cleaning dust adhered to the coating liquid 314, thereby achieving the purpose of cleaning the shielding curtain 306. At the same time, the provision of the through holes 3061 can also quickly dry the shielding curtain 306, increasing the drying efficiency of the shielding curtain 306, and preventing the shielding curtain 306 from becoming damp and breeding bacteria, thereby preventing bacterial growth.

[0075] In addition, both ends of the shielding curtain 306 are connected to a mounting plate 3062, and a sensing chip 3063 is provided in the mounting plate 3062. A sensor is provided on the inner wall of the avoidance groove 103. When the sensor senses the sensing chip 3063, the coating pump will start to coat the coating liquid 314 on the shielding curtain 306.

[0076] Preferably, the sensor may be an infrared sensor or an RFID reader / writer.

[0077] Furthermore, a control box is provided on the side wall of the crushing device body 1, and the crushing device body 1, circulation pump 201, control valve, heating wire 209, motor 1 303, sensor, motor 2 310, coating pump and cleaning pump are all electrically connected to the control box.

[0078] refer to Figures 1-11 As shown, a pulling mechanism is installed on the feed hopper 101, and the pulling mechanism corresponds to the shielding curtain 306. The pulling mechanism is used to pull the shielding curtain 306 to unfold, and then to block dust and prevent dust from overflowing and polluting the environment.

[0079] The pulling mechanism includes a pair of winding boxes 308, which are used to reel in or release the linkage rope 307. The winding box 308 is also provided with a rotating shaft 302 and a winding roller 304, and the linkage rope 307 is wound on the winding roller 304.

[0080] Preferably, the linkage rope 1 305 and the linkage rope 2 307 are both steel ropes.

[0081] In addition, a linkage shaft 309 is connected between a pair of winding boxes 308 so that the pair of winding boxes 308 can rotate synchronously. A linkage rope 307 is wound inside the winding box 308, and the linkage rope 307 is connected to the blackout curtain 306. The winding box 308 can pull or release the blackout curtain 306 through the linkage rope 307.

[0082] Specifically, one of the winding boxes 308 is connected to the motor 310, and the motor 310 is used to drive the winding box 308 to operate, and then to wind or release the linkage rope 307, so that the shielding curtain 306 can be unfolded or rolled up.

[0083] Preferably, both the motor 1 303 and the motor 2 310 are servo motors with a self-locking function.

[0084] refer to Figures 1-11 As shown, a coating box 311 is provided on one side of the winding box 301, and the shielding curtain 306 passes through the coating box 311 and enters the feed hopper 101 to accommodate a coating tube 312. A coating tube 312 is provided in the coating box 311, and the coating tube 312 is provided on the lower side of the shielding curtain 306. A plurality of coating nozzles are connected to the coating tube 312, that is, Figure 4 The coating nozzle is used to apply the coating liquid 314 to the shielding curtain 306. The coating liquid 314 can absorb the dust rising in the feed hopper 101, thereby preventing the dust from overflowing and polluting the environment.

[0085] A liquid storage tank 313 is provided below the coating tank 311. A coating pump and coating liquid 314 are provided in the liquid storage tank 313. The coating pump is located in the coating liquid 314. A delivery pipe is connected between the coating pump and the coating pipe 312. The coating pump extracts the coating liquid 314 and delivers the coating liquid 314 to the coating pipe 312.

[0086] Preferably, the coating liquid 314 is prepared by mixing glycerol and water in a ratio of 1:5.

[0087] In addition, a collection pipe is provided between the coating box 311 and the liquid storage box 313, so that the coating liquid 314 that is not coated on the shielding curtain 306 can re-enter the liquid storage box 313 through the collection pipe, thereby effectively avoiding the waste of the coating liquid 314 and reducing the overall cost.

[0088] refer to Figures 1-11 As shown, a cleaning mechanism 4 is installed on the crushing device body 1. The cleaning mechanism 4 is used to clean the shielding curtain 306 so that the shielding curtain 306 remains clean. At the same time, it can also quickly settle the dust in the feed hopper 101 that is not adsorbed by the coating liquid 314, thereby realizing dust treatment and improving the crushing efficiency of the crushing device body 1 for construction waste.

[0089] Among them, the cleaning mechanism 4 includes a cleaning box 401, which is provided with cleaning liquid and a cleaning pump. A pair of opposite side walls of the feed hopper 101 are connected to cleaning pipes 402, and a connecting pipe 403 is connected between the pair of cleaning pipes 402. A number of evenly distributed cleaning nozzles 404 are connected to the cleaning pipes 402. The cleaning nozzles 404 are arranged in the avoidance groove 102 and between the high-pressure nozzle 203 and the shielding curtain 306.

[0090] Preferably, the cleaning liquid is water.

[0091] By providing a pair of cleaning pipes 402 , the cleaning effect of the shielding curtain 306 can be greatly improved, and the sedimentation effect of the dust in the feed hopper 101 can also be greatly improved.

[0092] In addition, a protective cover 405 is provided on the outside of the cleaning tube 402 to protect the cleaning tube 402 .

[0093] Compared with the crushing device body 1 with a sealing mechanism on the market, the present invention can not only effectively prevent dust from overflowing and polluting the environment, but also absorb the dust floating in the feed hopper 101 and quickly settle the unabsorbed dust. When the staff opens the feed hopper 101 to put in other construction waste to be crushed, there is no dust in the feed hopper 101, thereby preventing the harm of dust to the staff and providing a good working environment for the staff.

[0094] A method for using an environmentally friendly construction waste treatment device comprises the following steps:

[0095] S1, adding construction waste into the crushing device body 1 through the feed hopper 101, and controlling the operation of the crushing device body 1;

[0096] S2. When the crushing device main body 1 is running, the circulation pump 201 is simultaneously turned on. The circulation pump 201 delivers gas to the positive pressure pipe. The gas is sprayed to the high-pressure nozzle 203 of the negative pressure pipe 202 through the high-pressure nozzle 203 of the positive pressure pipe, thereby forming an air curtain at the opening of the feed hopper 101 to block dust.

[0097] S3, the gas entering the negative pressure pipe 202 is transported through the return pipe 204, filtered through the purification box 205, and finally reused by the circulation pump 201;

[0098] S4. Control the operation of motor 1 303 and motor 2 310. Motor 2 310 drives one of winding boxes 2 308 to operate. The rotating winding box 2 308 drives the other winding box 2 308 to operate synchronously through the linkage shaft 309. The operation of winding box 2 308 can wind linkage rope 2 307. Motor 1 303 drives the rotating shaft 302 and winding roller 304 to rotate. The winding roller 304 releases linkage rope 1 305, thereby pulling the shielding curtain 306 to unfold and cover the opening of the feed hopper 101. The unfolded shielding curtain 306 is arranged on the lower side of the air curtain to further block dust and prevent dust from overflowing. At the same time, it can also reduce the pressure of the air curtain to block dust.

[0099] S5. During the unfolding process of the shielding curtain 306, when the first sensing chip 3063 is sensed by the sensor, the coating pump starts to operate, draws the coating liquid 314, and delivers it to the coating pipe 312 through the delivery pipe. The coating liquid 314 in the coating pipe 312 is sprayed toward the shielding curtain 306 through the coating nozzle, so that the coating liquid 314 adheres to the lower side of the shielding curtain 306 and covers the through hole 3061. When the second sensing chip 3063 is sensed by the sensor, the coating pump stops, and the coating liquid 314 on the shielding curtain 306 can adhere to the dust rising in the feed hopper 101, thereby achieving dust adsorption treatment;

[0100] S6. When the construction waste is crushed, the cleaning pump is turned on to extract cleaning fluid and transport it to the cleaning pipe 402. The cleaning fluid in the cleaning pipe 402 is sprayed into the feed hopper 101 through the cleaning nozzle 404. The air curtain can prevent the cleaning fluid from overflowing, thus avoiding the waste of cleaning fluid. The cleaning fluid will clean the coating fluid 314 on the shielding curtain 306 through the through hole 3061, and will also clean the dust adhered to the coating fluid 314, so that the dust falls into the feed hopper 101.

[0101] S7. Continuously operate the cleaning pump. The cleaning fluid can not only clean the shielding curtain 306, but also enter the lower side of the shielding curtain 306 through the through hole 3061 to quickly settle the unabsorbed dust in the feed hopper 101.

[0102] S8. When the shielding curtain 306 is cleaned, the cleaning pump is turned off, the heating wire 209 is controlled to operate, and the control valve is opened. Part of the gas generated by the circulation pump 201 enters the drying pipe 206 through the branch pipe 207 and is ejected through the drying nozzle 208. The heating wire 209 can instantly heat the gas ejected from the drying nozzle 208, thereby increasing the temperature of the gas ejected from the drying nozzle 208.

[0103] S9. Control the operation of motor 1 303 and motor 2 310. The winding roller 304 winds the linkage rope 1 305 and the shielding curtain 306. The winding box 2 308 releases the linkage rope 2 307, so that the shielding curtain 306 is rolled up. When the shielding curtain 306 passes through the gas sprayed by the drying nozzle 208, the sprayed gas can dry the wet shielding curtain 306 to prevent the shielding curtain 306 from being too wet and breeding bacteria. In addition, when the shielding curtain 306 is rolled up, the sensing chip 3063 will not be sensed by the sensor. When the shielding curtain 306 is completely rolled up on the winding roller 304, the circulation pump 201, motor 1 303 and motor 2 310 can be turned off.
