Abstract
Description
Technical Field
[0001] The invention relates to the field of rapid detection of solid waste pollution, in particular to a slag rapid detection probe. Background Art
[0002] With the acceleration of urban construction and development, the amount of construction waste (hereinafter referred to as waste) has increased sharply. Waste is mainly composed of waste soil, mud and engineering waste. At present, the common treatment methods are landfill, recycling and resource utilization. Because waste may contain pollutants such as heavy metals and organic matter, if it is blindly treated without pollution screening, it may cause contaminated waste to enter the treatment system, posing a threat to the environment and human health. In recent years, the country has attached increasing importance to the pollution control of solid waste. Therefore, the rapid pollution screening technology of waste is an important control method to respond to national environmental protection policies, strengthen the pre-management of waste treatment, and prevent pollution before it happens.
[0003] Soil rapid screening is an application scenario that is relatively close to this project. Commonly used rapid detection equipment for pollutants in the soil field include handheld X-ray fluorescence rapid detectors (hereinafter referred to as XRF), handheld photoionization detectors (hereinafter referred to as PID), etc. The above equipment is mostly used in the scene of contaminated site investigation and requires manual operation. In terms of the screening implementation site, the slag treatment site is relatively concentrated, while the building demolition site where the slag is produced is relatively scattered, so the import of the slag treatment site is selected as the screening site. In actual production, the import throughput of the slag treatment and disposal site is large and requires fast speed. It is not suitable for the use of the above handheld equipment, and requires automated integrated online detection equipment.
[0004] At present, the latest online slag detection system is the "Slag Sampling and Detection System for Slag Trucks" disclosed in the patent with publication number CN 115615739A previously applied by the applicant (with the same inventor as the present invention). This detection system has been put into use and has been promoted. The existing slag sampling and detection system for slag trucks uses a mechanical arm to connect the sampling assembly. When performing slag detection, the sampling assembly is moved to the top of the slag truck, and the sampling plate of the sampling assembly is inserted into the slag for sampling. After the sampling is completed, the slag sample is sent to the detection position by the mechanical arm, and the sampled slag is detected by the detection instrument set at the detection position. After the detection is completed, the mechanical arm drives the sampling shovel to move to the slag sampling collection container, and the sampled slag is pushed out from the sampling plate by the pusher mechanism set on the sampling assembly and loaded into the slag recovery assembly. The main problems of the system currently include: 1) When the soil moisture is too high, the sampling shovel cannot take enough samples, resulting in the inability to complete the detection work; 2) a large number of equipment such as robotic arms and servo motors are used, which is costly; 3) the detection equipment is not fully integrated, and the possibility of mechanical failure in the process of each detection equipment moving to the detection position is increased.

[0031] The technical scheme of the present invention is clearly and completely described below through embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] like Figure 1 As shown, the slag quick detection probe of the present invention includes a sliding seat component 1 and a detection component 2.
[0033] like Figure 2 As shown, the sliding seat assembly 1 includes an upper connecting seat 11 , a sliding block 12 , a sliding connecting seat 13 and a lower connecting seat 14 .
[0034] The upper connecting seat 11 is used to connect the displacement driving device, and the displacement driving device can be selected according to needs, for example, a mobile vehicle or a movable gantry can be selected. The upper connecting seat 11 can be a flange seat, and the upper connecting seat 11 and the flange seat at the free end of the displacement driving device are fixedly connected by multiple bolts to ensure the firmness and stability of the connection structure between the sliding seat assembly 1 and the displacement driving device.
[0035] like Figure 3 As shown, the slider 12 can be a slider with a T-shaped cross section. The slider 12 needs to be made of a material with a certain strength, such as a metal material or an alloy material. The top of the slider 12 is fixedly connected to the upper connecting seat 11, for example, two bolts can be used to connect the slider and the upper connecting seat; the lower part of the slider 12 is provided with a limit part, and the limit part is slidably connected with the sliding connecting seat 13.
[0036] The sliding connection seat 13 needs to be made of a material with a certain strength, such as metal or alloy material. A guide limit groove is provided on the sliding connection seat 13, and the limit portion at the lower part of the slider 12 is set in the guide limit groove. The slider 12 is slidably connected with the sliding connection seat 13 through the limit portion at its lower part.
[0037] The two ends of the guide limit groove extend to the front and rear sides of the sliding connection seat 13, respectively. Reset members are respectively provided on the front and rear sides of the sliding connection seat 13, and each set of reset members includes a tension spring 15 and two tension spring positioning columns 16. The two tension spring positioning columns 16 are respectively fixedly connected to the sliding connection seat 13 and are located on the left and right sides of the guide limit groove. The two ends of the tension spring 15 are respectively fixedly connected to the tension spring positioning columns 16.

[0038] like Figure 4 As shown, the detection assembly 2 includes a housing 21 , an XRF detector 25 , a PID detector 26 and a position sensor 29 .
[0039] The housing 21 includes a cylindrical portion and a bottom plate 22, and the bottom plate 22 is fixedly connected to the bottom of the cylindrical portion. The connection method between the bottom plate 22 and the cylindrical portion can be selected as needed, for example, the bottom plate 22 and the cylindrical portion can be connected using a flange structure.
[0040] A top plate is provided on the top of the cylindrical barrel, and a connection seat 23 corresponding to the lower connection seat 14 is provided on the top plate. The lower connection seat 14 and the connection seat 23 can be connected by a flange structure. In order to facilitate the wiring of the XRF detector 25 and the PID detector 26 in the housing 21, a wire hole is also provided on the top plate.
[0041] A plurality of position sensors 29 are provided on the outer side wall of the housing 21 . The position sensors 29 are used to detect the depths to which the XRF drill bit 252 of the XRF detector and the detection drill bit 266 of the PID detector 26 are inserted into the slag.
[0042] like Figure 5 As shown, an XRF detector 25 and a PID detector 26 are disposed in the housing 21 of the detection assembly 2 .
[0043] like Figure 6 As shown, the XRF detector 25 includes an XRF detector host 251 and an XRF drill bit 252 . The XRF detector host 251 is disposed in the housing 21 of the detection assembly 2 and fixed on the bottom plate 22 . The XRF drill bit 252 is fixedly connected below the bottom plate 22 .
[0044] like Fig.12 and 13 As shown, the XRF detector host 251 includes an XRF protective cover 2511, an X-ray module 2512 and a semiconductor detector 2513. The XRF protective cover 2511 is fixedly connected to the bottom plate 22 of the shell 21 of the detection component 2. The X-ray module 2512 and the semiconductor detector 2513 are fixedly arranged in the XRF protective cover 2511. The X-ray module 2512 is used to emit X-rays, and the semiconductor detector 2513 is used to receive secondary rays reflected from the slag. The heavy metal content in the slag can be calculated by analyzing and calculating the emitted X-rays and the received secondary rays through the processor.
[0045] The XRF drill bit 252 includes a cylindrical portion 2521 and a conical portion 2522, wherein the conical portion 2522 is fixedly connected to the lower end of the cylindrical portion 2521, a reflective lens for changing the direction of X-rays is provided in the cylindrical portion 2521, and an X-ray outlet is provided on the side wall of the cylindrical portion 2521, and the position of the X-ray outlet corresponds to the reflective lens. The positions of the X-ray outlet and the reflective lens can be set as required, for example, they can be set at the lower position of the cylindrical portion. Through this setting, the X-ray module 2512 emits X-rays, which are transmitted to the reflective lens and change direction, and are output from the X-ray outlet on the side wall of the cylindrical portion 2521 and enter the slag. The reflected rays enter the XRF drill bit 252 in the opposite direction, and the reflected rays are received by the semiconductor detector 2513. The XRF detector host 251 obtains the value of the heavy metal content in the slag by analyzing and calculating the received reflected rays.
[0046] The working principle of the XRF detector 25 is as follows: when the atoms of heavy metal elements contained in the slag sample are irradiated by high-energy X-rays, characteristic X-ray spectra with a certain energy are emitted, and the energy of the characteristic X-ray spectra is measured by the semiconductor detector 2513 to analyze the heavy metal concentration in the slag sample. According to the principle that the pulse height of the output signal of the semiconductor detector is proportional to the energy of the incident X-ray photons, when the semiconductor detector detects the characteristic X-ray spectrum of the slag sample, each channel of the semiconductor detector counts simultaneously, which can realize simultaneous measurement of multiple elements, and qualitative and quantitative analysis can be performed by detecting different characteristic X-ray energy positions and intensities.
[0047] like Figure 5 and 6 As shown, the PID detector 26 includes a PID detector main unit 261 and a detection drill bit 266 .
[0048] like Figure 5-7 As shown, a vertical fixed seat plate 262 is provided on the bottom plate 22 of the shell 21 of the detection component 2, and the PID detector host 261 is fixedly connected to the fixed seat plate 262. The connection method can be selected according to needs. For example, a semicircular clamp 263 is used to fix the PID detector host 261 on the fixed seat plate 262.
[0049] like Figure 7 As shown, an air pipe 264 is provided at the lower end of the PID detector main unit 261, a through hole is provided on the bottom plate 22 of the shell 21 of the detection component 2, and an air pipe joint 265 is provided on the upper part of the through hole. The lower end of the air pipe 264 is fixedly connected to the air pipe joint 265, and the detection drill bit 266 is fixedly connected to the lower surface of the bottom plate 22 at a position corresponding to the through hole, and a vent is provided on the detection drill bit 266. The vent on the detection drill bit 266 is connected to the PID detector main unit 261 through the air pipe joint 2665 and the air pipe 264.
[0050] The structure of the detection drill bit 266 can be designed as required, such as Figure 8The first embodiment of the detection drill bit 266 is shown. The detection drill bit 266 includes a connecting plate 268, a cylindrical portion 2661 and a conical portion 2662. The upper end of the cylindrical portion 2661 is fixedly connected to the connecting plate 268, and the conical portion 2662 is fixedly connected to the lower end of the cylindrical portion 2661. The cylindrical portion 2661 is a hollow pipe. The vent hole 267 is arranged on the side wall of the cylindrical portion 2661. An assembly groove is arranged on the lower surface of the bottom plate 22. The through hole on the bottom plate is located in the middle of the assembly groove. A filter plate 269 is arranged at the through hole. The connecting plate 268 is arranged below the filter plate 269 and is fixedly connected to the assembly groove. Through this arrangement, the detection drill bit is easier to break through the soil layer and insert into the soil. By setting the filter plate 269, it can prevent the slag from entering the air pipe joint 265, and keep the air flow channel unobstructed.
[0051] Through this arrangement, when the slag is detected, the detection drill bit 266 breaks through the surface layer of the slag and is inserted into the slag, so that the gas in the slag enters the PID detector host 261 through the vent hole 267, the air pipe joint 265, and the air pipe 264 on the detection drill bit 266, and the VOCs gas content in the slag is detected through the PID detector host 261.
[0052] like Figure 9-10 The second embodiment of the drill bit detection method, the drill bit detection method 266 includes a connection plate 268, a cylindrical portion 2661 and a conical portion 2662. The upper end of the cylindrical portion 2661 is fixedly connected to the connection plate 268, and the conical portion 2662 is fixedly connected to the lower end of the cylindrical portion 2661. A mounting groove is provided on the lower surface of the bottom plate 22, the through hole on the bottom plate is located in the middle of the mounting groove, and the connection plate 268 is fixedly connected to the mounting groove. The cylindrical part 2661 is a hollow pipe, the vent hole 267 is arranged on the side wall of the cylindrical part 2661, a vent bolt 2663 is arranged in the vent hole 267, the vent bolt 2663 is threadedly connected to the inner wall of the vent hole 267, an air flow channel is arranged in the vent bolt 2663, the air flow channel is connected to the air flow channel inside the detection drill bit 266, and a filter screen 2664 for preventing mud from entering the channel is arranged on the vent bolt 2663. Through this arrangement, the air flow channel can be kept unblocked, and the channel can be prevented from being blocked by debris entering the channel.
[0053] The working principle of the PID detector 26 is as follows: The PID detector (photoionization detector) uses an ultraviolet (UV) light source to ionize organic matter into positive and negative ions (ionization) that can be detected by the detector. Under the action of an external electric field, the ions are offset to form a weak current. Since the concentration of the gas substance being measured is linearly related to the photoionization current, the current signal is amplified and converted into a "ppm" or "ppb" concentration value. The PID detector has a high sensitivity. Through high-energy ultraviolet light, most organic matter and some inorganic matter can be ionized. During the detection process, basic components in the air such as nitrogen, oxygen, carbon dioxide, etc. are not ionized, and there is no interference with the detection results, so the content of VOCs gas in the slag can be accurately detected.
[0054] like Figure 5 and 6 As shown, as a preferred solution, a pH value detector and a slag moisture detector can also be set in the shell 21.
[0055] The pH detector includes a pH detector main body 27 and a pH detection probe 271. The pH detector main body 27 is arranged in the housing 21. The pH detection probe 271 is arranged at the lower end of the pH detector. The pH detection probe 271 passes through the bottom plate 22 and extends to the bottom of the bottom plate 22. The pH value of the slag can be detected by setting the pH detector, because the pH detection probe 271 extends to the bottom of the bottom plate 22. During detection, the pH detection probe 271 can be inserted into the slag to directly detect the pH value of the slag.
[0056] The pH value detector can be a soil acidity meter, which is composed of electrodes, metal probes and function value switching devices. When the soil acidity meter is working, the metal probe contacts the soil, measures the potential difference between the two electrodes, and infers the hydrogen ion concentration in the soil, thereby calculating the pH.
[0057] The soil humidity detector includes a soil humidity detector host 28 and a soil humidity detection probe 281. The soil humidity detector host 28 is arranged in the housing 21. The soil humidity detection probe 281 is arranged at the lower end of the soil humidity detector. The soil humidity detection probe 281 passes through the bottom plate 22 and extends to the bottom of the bottom plate 22. This arrangement can directly detect the humidity of the soil.
[0058] The soil moisture detector can use the frequency domain reflectometry (FDR technology) to detect the moisture content of soil. The FDR technology uses the characteristics of electromagnetic waves propagating in soil. When electromagnetic waves propagate in dry soil, the propagation speed of electromagnetic waves is faster due to the friction and damping between soil particles. When the soil contains moisture, the presence of moisture increases the dielectric constant of the soil, thereby reducing the propagation speed of electromagnetic waves. The FDR technology infers the moisture content of the soil by measuring the speed of electromagnetic waves propagating in the soil.
[0059] The detection component of the slag quick detection probe of the present invention needs to be connected to the displacement drive device before use, and the connection lines of the XRF detector, PID detector, position sensor, pH detector and slag humidity detector need to be connected to the external power supply and data acquisition equipment respectively. When performing detection, the detection component is driven by the displacement drive device to move to the top of the slag truck, and then the detection drill bit of the PID detector, the detection head of the XRF detector, and the probes of the pH detector and the slag humidity detector under the mounting plate of the detection component are inserted into the slag to be detected, and the depth of insertion into the soil is detected by the position sensor. When the predetermined insertion depth is reached, the displacement drive device stops descending, and the heavy metal content, VOCs gas content, pH value and humidity data in the slag are detected by the XRF detector, PID detector, pH detector and slag humidity detector, and the detected data are transmitted to the data acquisition equipment; after the detection is completed, the displacement drive device drives the detection component to leave the slag and return to the initial position for the next detection. When the detection drill bit of the PID detector, the detection head of the XRF detector, and the probes of the pH value detector and the slag moisture detector are inserted into the slag to be detected by the displacement driving device, if hard objects such as stones are encountered and the resistance is very large, the relative sliding of the slider on the sliding seat assembly and the sliding connecting seat can form a buffer protection for the detection drill bit of the PID detector, the detection head of the XRF detector, and the probes of the pH value detector and the slag moisture detector to prevent them from being damaged; and the reset parts arranged on the front and rear sides of the sliding connecting seat can automatically reset the relative displacement of the slider and the sliding connecting seat to keep the positional relationship between the two stable, and the wire rope arranged between the upper connecting seat and the lower connecting seat can limit the relative range of movement between the upper connecting seat and the lower connecting seat to prevent the slider from detaching from the sliding connecting seat.
[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
