Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction waste classification and collection, and particularly relates to a vertical conveying and sorting device for construction waste. BACKGROUND

[0002] At present, a large amount of construction waste is generated and accumulated in each floor during the construction process of a building project, and the waste is usually transported by a waste pipeline. However, the degree of classification and collection of the construction waste is low, and most of the waste is collected in a mixed manner, which increases the difficulty of waste resource utilization and harmless treatment.

Each floor is provided with a floor waste outlet, and adjacent floor waste outlets are connected by a conveying channel. The lowermost floor waste outlet or the lower part of the conveying channel is provided with a construction waste conveying channel and a decoration waste conveying channel. An electric flap device is arranged between the construction waste conveying channel and the decoration waste conveying channel. A particle size separation channel is arranged at the lower part of the construction waste conveying channel. The lower part of the particle size separation channel and the decoration waste conveying channel is provided with a mobile waste collection vehicle. The device realizes automatic and efficient classification of construction waste in stages, types and particle sizes.

[0004] In the above prior art, an electric movable flap device is arranged, which can be switched according to the civil construction stage and the decoration construction stage, and construction waste generated in different construction stages is introduced into different separation channels. However, for the waste generated in the decoration construction stage, it is only discharged into one waste collection vehicle, and cannot be classified.

DETAILED DESCRIPTION

[0036] The application will be described in further detail below with reference to the drawings and specific embodiments.

[0037] The embodiment aims to provide a construction waste vertical conveying and sorting device, which is mainly used for sorting the construction waste transported through the vertical waste channel 3 in the construction process, and aims to solve the problem that the existing waste classification device based on the vertical conveying channel is difficult to effectively sort the construction waste generated in the decoration and renovation stage.

[0038] A construction waste vertical conveying and sorting device, such as Figure 1 and Figure 2 , comprises a buffer channel 1, a sorting chamber 2, a heavy sorting channel and a light sorting channel.

[0039] The upper end of the buffer channel 1 is used for communication with the vertical waste channel 3, and the vertical waste channel 3 is used for vertically conveying the construction waste from each floor downward, and each floor is provided with a floor waste port in communication with the vertical waste channel 3. The specific structure and principle of the vertical waste channel 3 are prior art, but it needs to be emphasized that the embodiment is based on the vertical waste channel 3 and is arranged at the construction site, and can be simultaneously applied to the civil construction stage and the decoration and renovation construction stage, and especially for the preliminary sorting of pollutant waste in the decoration and renovation construction stage, so as to facilitate the further systematic classification of the construction waste.

[0040] As Figure 1 , the buffer channel 1 is mainly used for buffering and decelerating the vertically conveyed waste, the upper end of the sorting chamber 2 is in communication with the lower end of the buffer channel 1, the speed and kinetic energy of the waste when entering the sorting chamber 2 are reduced, so as to facilitate sorting, and the buffer channel 1 is an inclined downward pipeline, and a layer of buffer pad 101 is fixed at the bottom of the buffer channel 1 to cope with the impact of the vertically conveyed waste.

[0041] As Figures 1-3The side wall of the sorting chamber 2 is provided with an air separation opening 201, and a fan 202 for delivering air to the air separation opening 201 is arranged in the sorting chamber 2. Specifically, a blowing opening is formed in the side wall of the sorting chamber 2 opposite to the air separation opening 201, and the fan 202 is fixedly installed on the blowing opening. A filter screen is fixed on the blowing opening. When the fan 202 is in operation, air can be provided to the sorting chamber 2 to blow the light-weight garbage in the garbage to the air separation opening 201, and then to the light-weight detection channel 8, while the heavy-weight garbage continues to be delivered downward to the heavy-weight detection channel 4, so as to realize the separation of light-weight garbage and heavy-weight garbage. The power and on-off of the fan 202 are controlled by the controller. The specific structure and working principle of the fan 202 are the same as those of the prior art, and will not be described here. It should be emphasized that in the present embodiment, the fan 202 is used to separate the light-weight garbage and the heavy-weight garbage, which is combined with the vertical delivery of the garbage in the vertical garbage channel 3 to preliminarily separate the light-weight garbage and the heavy-weight garbage, so that the air flow perpendicular to the flow direction of the garbage can effectively separate the light-weight garbage and the heavy-weight garbage.

[0042] In the decoration and renovation construction stage, the light-weight garbage mainly includes packaging paper, foam material, plastic film and dust, the heavy-weight garbage mainly includes bricks, concrete blocks and ceramic pieces, and the pollutants mainly include paint and varnish attached or covered on the surface of the garbage. The present embodiment is mainly aimed at sorting out the garbage containing paint and varnish. Since the light-weight garbage such as packaging paper, foam material and plastic film usually has a large volume and is easy to cover and shield the heavy-weight garbage, and the dust will adversely affect the detection result, the light-weight garbage and the heavy-weight garbage are separated by the method of light-weight separation and heavy-weight separation in the present embodiment, and are detected separately, and the detection of the pollutants of specific types of garbage can be relatively focused, so as to improve the detection accuracy.

[0043] As shown in FIG. 1, Figure 1 The heavy-weight detection channel 4 is in communication with the lower end of the sorting chamber 2, and the lower end of the heavy-weight detection channel 4 is in communication with the heavy-weight pollutant channel 5 and the heavy-weight non-pollutant channel 6. Specifically, the heavy-weight detection channel 4, the heavy-weight pollutant channel 5 and the heavy-weight non-pollutant channel 6 form a three-pronged communication structure. The lower end of the heavy-weight detection channel 4 is provided with a first electrically-driven flap 7. Specifically, the first electrically-driven flap 7 includes a shaft seat, a rotating shaft, a flap and a corner motor. The shaft seat is fixed on the intersection line of the heavy-weight pollutant channel 5 and the heavy-weight non-pollutant channel 6. The flap is rotatably arranged on the shaft seat through the rotating shaft. The rotating shaft is in transmission connection with the rotating shaft of the corner motor. The corner motor is in control connection with the controller. By rotating the first electrically-driven flap 7, the communication relationship between the heavy-weight detection channel 4 and the heavy-weight pollutant channel 5 and the heavy-weight non-pollutant channel 6 can be switched.

[0044] As shown in FIG. 1, Figure 2The light weight sorting channel includes a light weight detection channel 8, a light weight contaminant channel 9 and a light weight non-contaminant channel 10. The upper end of the light weight detection channel 8 is in communication with the winnowing port 201 of the sorting chamber 2, the lower end of the light weight detection channel 8 is in communication with the light weight contaminant channel 9 and the light weight non-contaminant channel 10, and the lower end of the light weight detection channel 8 is provided with a second electric flap 11. Specifically, the shaft seat of the second electric flap 11 is fixed on the intersection line of the light weight contaminant channel 9 and the light weight non-contaminant channel 10, and the communication relationship between the light weight contaminant channel 9 and the light weight non-contaminant channel 10 is switched through the second electric flap 11. The specific structure and working principle of the second electric flap 11 are the same as those of the first electric flap 7, which will not be described here.

[0045] The detection unit 12 for identifying contaminants is arranged in the heavy weight detection channel 4 and the light weight detection channel 8, and the detection unit 12 includes a spectrum sensor. Paint and coating are usually composed of pigments, resins, solvents and additives, some chemical groups (such as hydroxyl, carboxyl, aromatic ring, etc.) have absorption or reflection characteristics for specific wavelengths of light, and different types of coatings (such as water-based paint, oil-based paint) have unique spectral characteristics in the ultraviolet, visible and near-infrared spectral range. The spectrum sensor uses a light source (such as laser, LED) to irradiate the surface of the garbage, and the paint coating will absorb light of a specific wavelength and reflect light of other wavelengths. The spectrum sensor captures the reflected or transmitted light signal, converts the signal into a spectrum curve through a spectrum analysis algorithm (such as Fourier transform or convolution analysis), and finally compares the spectrum curve of the garbage with the known paint coating spectral characteristic database to identify the type of coating and whether there is contamination. As for identifying paint coating attached to solid by spectrum sensor, it belongs to the prior art, which will not be described here. In other embodiments, the detection unit 12 can also include a color sensor, which can preliminarily screen bright color paint coating by identifying the bright color characteristics of paint coating to assist in identifying contaminants.

[0046] The detection unit 12, the first electric flap 7 and the second electric flap 11 are all connected with the controller. The controller is selected as a single-chip microcomputer based on an embedded control system, which is mainly used for receiving signals of the detection unit 12 and controlling the actions of the controlled external devices such as the first electric flap 7 and the second electric flap 11. The specific structure and principle of the controller all adopt the prior art, which will not be described here.

[0047] As to the sorting of the controller according to the detection unit 12 to the pollutants, the detection and sorting principles of the light-weight pollutants and the heavy-weight pollutants are the same, and the detection of the heavy-weight pollutants is taken as an example for description. The first electric flap 7 initially blocks the heavy-weight pollutant channel 5, when the detection unit 12 detects the pollutants in the heavy-weight detection channel 4, the controller controls the first electric flap 7 to rotate, opens the heavy-weight pollutant channel 5, and blocks the heavy-weight non-pollutant channel 6, the state is maintained for a delay period, the garbage containing the pollutants is discharged into the heavy-weight pollutant channel 5, if the detection unit 12 detects the pollutants again within the delay period, the delay period is recalculated, until the delay period ends, the electric flap resets, opens the heavy-weight non-pollutant channel 6, and blocks the heavy-weight pollutant channel 5, finally, the garbage flow containing the pollutants is discharged into the heavy-weight pollutant channel 5, and the effect of preliminary automatic sorting of the pollutants is achieved, rather than the pollutants being removed alone. As to the delay period, it can be set according to the actual situation, or a flow rate meter for detecting the garbage flow rate can be integrated in the detection unit 12, and the delay period is calculated according to the real-time flow rate of the garbage, so as to ensure that the pollutants detected in the heavy-weight detection channel 4 enter the heavy-weight pollutant channel 5.

[0048] Further, as shown in Figure 1 and Fig. 3, the sorting chamber 2 is further provided with a magnetic attraction device 13, the magnetic attraction device 13 includes a mounting frame 1301 and an electromagnet 1302, the mounting frame 1301 is fixed on the side wall of the sorting chamber 2, the electromagnet 1302 is installed on the mounting frame 1301 and is in control connection with the controller, the controller can control the on-off of the electromagnet 1302, so that the electromagnet 1302 has or loses magnetic attraction force, and the electromagnet 1302 is mainly used for adsorbing the metal objects in the garbage, including reinforcing steel bars, angle steels, screws, etc. Due to the high recycling value of the metal objects, the metal objects adhered with the pollutants are no longer sorted alone in the embodiment, and the metal objects are mainly collected alone and uniformly, and the pollutants therein are cleaned in the subsequent garbage treatment process.

[0049] Further, as shown in Figure 3 , a gravity sensor 1303 is arranged between the mounting frame 1301 and the electromagnet 1302, the gravity sensor 1303 is in control connection with the controller, the controller analyzes the data returned by the gravity sensor 1303 to determine whether the electromagnet 1302 is full or not. As shown in Figure 1The lower end of the sorting chamber 2 is also connected to a metal transport channel 15. A third electric flap 14 is installed between the metal transport channel 15 and the heavy metal detection channel 4. The lower end of the sorting chamber 2 switches the connection between the metal transport channel 15 and the heavy metal detection channel 4 through the third electric flap 14. The third electric flap 14 is connected to the controller. In the initial state, the third electric flap 14 blocks the metal transport channel 15. However, when the electromagnet 1302 is fully loaded, the third electric flap 14 flips to open the metal transport channel 15 and simultaneously blocks the heavy metal detection channel 4. Then the electromagnet 1302 is de-energized, and the metal objects that lose their attraction fall and slide into the metal recovery channel, realizing the separate recovery of the metal objects. After a preset delay period, the third electric flap 14 resets, and the electromagnet 1302 is re-energized. The specific structure of the third electric flap 14 is the same as that of the first electric flap 7, and will not be described again here.

[0050] Furthermore, such as Figure 2 A dust conveying channel 16 is also provided between the air separator 201 and the lightweight detection channel 8. The upper part of the dust conveying channel 16 is horizontally connected to the air separator 201, and the lower part of the dust conveying channel 16 extends vertically downward after a bend, thereby creating a wind-relieving effect in the bend area, reducing the speed of lightweight waste, and preventing the wind from affecting subsequent sorting. A dust sorting screen 1601, which only allows dust to pass through, is inclinedly installed in the middle of the dust conveying channel 16. Combined with the vertical conveying action of the vertical section of the dust conveying channel 16, it is used to separate dust from lightweight waste. The upper end of the lightweight detection channel 8 is connected to the dust conveying channel 16, and the connection point is located at the lowest point of the dust sorting screen 1601, allowing lightweight waste such as plastic film and packaging paper to enter the lightweight detection channel 8. Separating dust from lightweight waste separately is mainly to prevent dust from affecting the spectral sensor.

[0051] Furthermore, a particle size separation channel 17 is connected to the lower end of the heavy-duty non-contamination channel 6. The particle size separation channel 17 is inclined downwards, and a number of particle size separation ports are spaced apart on the lower surface of the particle size separation channel 17 along the inclined direction. Each of the particle size separation ports is connected to an independent particle size conveying channel 18. A screening screen 19 is provided on each particle size separation port, and the aperture of the screening screen 19 arranged from top to bottom gradually increases.

[0052] Furthermore, garbage collection vehicles 22 are placed at the ends of the light pollutant channel 9, the light non-polluting channel 10, the heavy pollutant channel 5, and the metal transport channel 15. Garbage collection vehicles 22 are also arranged below each particle size transport channel 18 to facilitate garbage collection. The lower end of the dust transport channel 16 is connected to the particle size transport channel 18 with the smallest sorting particle size.

[0053] Further, the heavy pollutant channel 5 and the light pollutant channel 9 are provided with secondary detection units 20, the secondary detection units 20 include spectrum sensors, the secondary detection units 20 are in control connection with the controller, the secondary detection units 20 mainly play an auxiliary detection role, and are used for judging whether the pollutants successfully enter the pollutant channel; on the basis, the control logic of the first and second electric flaps 11 can be optimized; here, the first electric flap 7 is still taken as an example; when the detection unit 12 first detects the pollutants in the heavy pollutant channel 5, the first electric flap 7 is turned over, and the garbage with the pollutants is discharged into the heavy pollutant channel 5; when the secondary detection unit 20 does not detect the pollutants again in a short period, the first electric flap 7 is reset, and the heavy pollutant channel 5 is closed. That is, the detection unit 12 focuses on controlling the opening of the heavy pollutant channel 5, and the secondary detection unit 20 focuses on controlling the closing of the heavy pollutant channel 5; compared with the control mode of relying on only a single detection unit 12 to control the first electric flap 7 in time, the control mode has better sensitivity and fault tolerance.

[0054] Further, the buffer channel 1, the heavy detection channel 4, the light detection channel 8, the heavy pollutant channel 5 and the light pollutant channel 9 are all provided in a downward inclined manner; the heavy detection channel 4 and the heavy pollutant channel 5 keep the same inclination direction, and the light detection channel 8 and the light pollutant channel 9 keep the same inclination direction, so as to slow down the garbage in the channels and increase the spacing between the garbage individuals, thereby facilitating the pollutant detection.

[0055] Further, the buffer channel 1 is provided with a trigger unit 21 for detecting the passing garbage, the trigger unit 21 includes a laser sensor, the trigger unit 21 is in control connection with the controller, and can also include an ultrasonic sensor and the like; the trigger unit 21 mainly serves to identify whether there is garbage passing by; when there is garbage passing by, a feedback signal is fed back to the controller, so that the fan 202 and the detection unit 12 can enter a standby state when there is no garbage passing by, and are activated into a working mode only when there is garbage passing by.
