Description

TECHNICAL FIELD

[0001] The utility model relates to solid waste pollution rapid detection field especially relates to a quick detection probe for slag. BACKGROUND

[0002] With the acceleration of urban construction development process, the production quantity of construction slag (hereinafter referred to as slag) rises sharply. The slag is mainly composed of waste soil, mud and engineering garbage. At present, the common treatment methods are landfill, recycling and resource utilization. Because the slag may contain heavy metals, organic matter and other pollutants, if the pollution screening is not carried out and the slag is blindly treated, the contaminated slag may enter the treatment system, which may pose a threat to the environment and human health. In recent years, the state has increasingly paid attention to solid waste pollution control. Therefore, the rapid pollution screening technology of slag is an important control means to respond to the state environmental protection policy, strengthen the pre-management of slag treatment and prevent pollution.

[0003] The soil quick screening is an application scenario close to the project. The common rapid detection equipment for pollutants in the soil field includes a handheld X-ray fluorescence rapid detection instrument (hereinafter referred to as XRF), a handheld photoionization detector (hereinafter referred to as PID) and the like. The above equipment is mainly used in the scene of pollution site investigation and needs to be manually operated. In terms of screening implementation sites, the slag treatment sites are relatively concentrated, while the construction sites where the slag is produced are relatively scattered. Therefore, the inlet of the slag treatment site is selected as the screening site. In actual production, the inlet of the slag treatment site has a large throughput and requires a high speed, so the above handheld equipment is not suitable and more online detection equipment integrated by automation is needed.

[0004] At present, the latest slag online detection system is the slag sampling and detection system for a slag truck disclosed in the patent with the publication number CN 115615739A previously declared by the applicant (the same inventor as the present utility model), which has been put into application and has been popularized. The existing slag sampling and detection system for a slag truck uses a mechanical arm to connect a sampling assembly. When the slag is detected, the sampling assembly is moved above the slag truck, the sampling plate of the sampling assembly is inserted into the slag for sampling, after the sampling is completed, the mechanical arm sends the slag sample to a detection position, the detection instrument arranged at the detection position is used to detect the sampled slag, after the detection is completed, the mechanical arm drives the sampling shovel to move to a slag sampling and collecting container, the sampled slag is pushed out from the sampling plate by the bulldozing mechanism arranged on the sampling assembly and is loaded into the slag recycling assembly. The main problems of the system at present include: 1) when the soil humidity is too large, the sampling shovel cannot take enough sample, which leads to the failure of the detection work; 2) the mechanical arm, servo motor and other equipment are used, which has a high cost; 3) the detection equipment is not fully integrated, and the possibility of mechanical failure increases during the movement of each detection equipment to the detection position.

DETAILED DESCRIPTION

[0034] The technical solutions of the present application will be described clearly and completely below through embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] As Figure 1As shown, the rapid detection probe for slag and soil of this utility model includes a sliding seat assembly 1 and a detection assembly 2.

[0036] like Figure 2 As shown, the sliding seat assembly 1 includes an upper connecting seat 11, a slider 12, a sliding connecting seat 13, and a lower connecting seat 14.

[0037] The upper connecting seat 11 is used to connect the displacement drive device, which can be selected as needed, such as a mobile vehicle or a mobile gantry. The upper connecting seat 11 can be a flange seat, and the upper connecting seat 11 is fixedly connected to the flange seat at the free end of the displacement drive device by multiple bolts to ensure the firmness and stability of the connection structure between the sliding seat assembly 1 and the displacement drive device.

[0038] like Figure 3 As shown, slider 12 can be a slider with a T-shaped cross section. Slider 12 needs to be made of a material with a certain strength, such as metal or alloy. The top of slider 12 is fixedly connected to the upper connecting seat 11, for example, two bolts can be used to connect slider and upper connecting seat; the lower part of slider 12 is provided with a limiting part, which is slidably connected to sliding connecting seat 13.

[0039] The sliding connector 13 needs to be made of a material with a certain strength, such as metal or alloy. The sliding connector 13 is provided with a guide limiting groove. The limiting part of the lower part of the slider 12 is set in the guide limiting groove. The slider 12 is slidably connected to the sliding connector 13 through the limiting part at its lower part.

[0040] The two ends of the guide limiting groove extend to the front and rear sides of the sliding connecting seat 13, respectively. Reset members are provided on the front and rear sides of the sliding connecting seat 13. Each set of reset members includes a tension spring 15 and two tension spring positioning posts 16. The two tension spring positioning posts 16 are fixedly connected to the sliding connecting seat 13 and located on the left and right sides of the guide limiting groove, respectively. The two ends of the tension spring 15 are fixedly connected to the tension spring positioning posts 16. With this arrangement, the slider 12 and the sliding connecting seat 13 can slide relative to each other, and when the slider 12 and the sliding connecting seat 13 slide relative to each other, they can automatically reset due to the action of the tension spring 15 of the reset member.

[0041] like Figure 4 As shown, the detection component 2 includes a housing 21, an XRF detector 25, a PID detector 26, and a position sensor 29.

[0042] The housing 21 includes a cylindrical section and a base plate 22, with the base plate 22 fixedly connected to the bottom of the cylindrical section. The connection method between the base plate 22 and the cylindrical section can be selected as needed; for example, the base plate 22 and the cylindrical section can be connected using a flange structure.

[0043] The top of the cylindrical barrel is provided with a top plate, and a connecting seat 23 corresponding to the lower connecting seat 14 is arranged on the top plate. The lower connecting seat 14 and the connecting seat 23 can be connected in a flange structure. In order to facilitate the wiring of the XRF detector 25 and the PID detector 26 in the shell 21, a wire hole is further arranged on the top plate.

[0044] A plurality of position sensors 29 are arranged on the outer side wall of the shell 21. The position sensors 29 are used to detect the depth of the XRF drill bit 252 of the XRF detector and the detection drill bit 266 of the PID detector 26 inserted into the muck.

[0045] As shown in Figure 5 , the XRF detector 25 and the PID detector 26 are arranged in the shell 21 of the detection assembly 2.

[0046] As shown in Figure 6 , the XRF detector 25 includes an XRF detector host 251 and an XRF drill bit 252. The XRF detector host 251 is arranged in the shell 21 of the detection assembly 2 and is fixed to the bottom plate 22. The XRF drill bit 252 is fixedly connected below the bottom plate 22.

[0047] As shown in Figure 12 and 13 , 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 assembly 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. The semiconductor detector 2513 is used to receive secondary rays reflected from the muck. Through analysis and calculation of the emitted X-rays and the received secondary rays by a processor, the heavy metal content in the muck can be calculated.

[0048] The XRF drill bit 252 includes a cylindrical part 2521 and a conical part 2522. The conical part 2522 is fixedly connected to the lower end of the cylindrical part 2521. A mirror for changing the direction of X-rays is arranged in the cylindrical part 2521. An X-ray outlet is arranged on the side wall of the cylindrical part 2521. The position of the X-ray outlet corresponds to the position of the mirror. The positions of the X-ray outlet and the mirror can be set as needed, for example, they can be arranged at the lower part of the cylindrical part. Through this arrangement, the X-ray module 2512 emits X-rays. The X-rays are transmitted to the mirror to change direction, output from the X-ray outlet on the side wall of the cylindrical part 2521, and enter the muck. The reflected rays enter the XRF drill bit 252 in the opposite direction. The reflected rays are received by the semiconductor detector 2513. The XRF detector host 251 obtains the numerical value of the heavy metal content in the muck through analysis and calculation of the received reflected rays.

[0049] The working principle of the XRF detector 25 is that when the atoms of heavy metal elements contained in the slag sample are irradiated by high-energy X-rays, characteristic X-ray spectrum with certain energy is emitted, and the energy of the characteristic X-ray spectrum 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 semiconductor detector output signal is proportional to the incident X-ray photon energy, when the semiconductor detector detects the characteristic X-ray spectrum of the slag sample, each channel of the semiconductor detector counts at the same time, and multi-element simultaneous measurement can be realized. Qualitative and quantitative analysis is carried out by detecting different characteristic X-ray energy positions and intensities.

[0050] As shown in Figure 5 and 6 PID detector 26 includes PID detector host 261 and detection drill bit 266.

[0051] As shown in Figures 5-7 A vertical fixed seat plate 262 is arranged on the bottom plate 22 of the shell 21 of the detection assembly 2, and the PID detector host 261 is fixedly connected to the fixed seat plate 262. The connection mode can be selected as needed, for example, a semicircular clamp 263 is used to fix the PID detector host 261 on the fixed seat plate 262.

[0052] As shown in Figure 7 A gas pipe 264 is arranged at the lower end of the PID detector host 261, a through hole is arranged on the bottom plate 22 of the shell 21 of the detection assembly 2, a gas pipe joint 265 is arranged at the upper part of the through hole, the lower end of the gas pipe 264 is fixedly connected to the gas pipe joint 265, and the detection drill bit 266 is fixedly connected to the position corresponding to the through hole on the lower surface of the bottom plate 22.

[0053] The structure of the detection drill bit 266 can be designed as needed, such as Figure 8The first embodiment of the detection drill bit 266 is shown, which comprises a connecting disc 268, a cylindrical part 2661 and a conical part 2662. The upper end of the cylindrical part 2661 is fixedly connected with the connecting disc 268, and the conical part 2662 is fixedly connected with the lower end of the cylindrical part 2661. The cylindrical part 2661 is a hollow pipe, and the air hole 267 is arranged on the side wall of the cylindrical part 2661. The bottom plate 22 is provided with an assembly groove on the lower surface, and the through hole of the bottom plate is located in the middle of the assembly groove. The filter plate 269 is arranged at the through hole, and the connecting disc 268 is arranged below the filter plate 269 and is fixedly connected with the assembly groove. Through this arrangement, the detection drill bit is easier to break through the soil layer and insert into the soil. By arranging the filter plate 269, the slag soil can be prevented from entering the air pipe joint 265, and the air flow channel is kept unobstructed.

[0054] Through this arrangement, when the slag soil is detected, the detection drill bit 266 breaks through the surface layer of the slag soil and inserts into the slag soil, so that the gas in the slag soil enters the PID detector host 261 through the air hole 267 on the detection drill bit 266, the air pipe joint 265 and the air pipe 264, and the content of VOCs gas in the slag soil is detected by the PID detector host 261.

[0055] As shown in FIG. 6, the detection drill bit 266 is arranged on the bottom plate 22, and the connecting disc 268 is fixedly connected with the assembly groove of the bottom plate 22. The cylindrical part 2661 is a hollow pipe, and the air hole 267 is arranged on the side wall of the cylindrical part 2661.

Figures 9-10 The second embodiment of the detection drill bit is shown, which comprises a connecting disc 268, a cylindrical part 2661 and a conical part 2662. The upper end of the cylindrical part 2661 is fixedly connected with the connecting disc 268, and the conical part 2662 is fixedly connected with the lower end of the cylindrical part 2661.

The air hole screw bolt 2663 is arranged in the air hole 267, which is threadedly connected with the inner wall of the air hole 267. The air hole screw bolt 2663 is provided with an air flow channel, which is connected with the air passage in the detection drill bit 266. The air hole screw bolt 2663 is provided with a filter screen 2664 for preventing the soil from entering the channel.

[0056] The working principle of the PID detector 26 is as follows: the PID detector (photo ionization detector) uses a UV light source to ionize the 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 deviate to form a weak current. Since the concentration of the measured gas substance 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 high sensitivity. Through high-energy ultraviolet light, most organic matter and part of inorganic matter can be ionized. In the detection process, the basic components in the air such as nitrogen, oxygen, and carbon dioxide are not ionized and do not interfere with the detection results, so the content of VOCs gas in the slag soil can be accurately detected.

[0057] As shown in Figure 5 and 6 , as a preferred solution, a pH detector and a slag soil humidity detector can also be arranged in the shell 21.

[0058] The pH detector includes a pH detector host 27 and a pH detection probe 271. The pH detector host 27 is arranged in the shell 21, and the lower end of the pH detector is provided with the pH detection probe 271, which extends below the bottom plate 22 through the bottom plate 22. By arranging the pH detector, the pH value of the slag soil can be detected. Since the pH detection probe 271 extends below the bottom plate 22, the pH detection probe 271 can be inserted into the slag soil during detection to directly detect the pH value of the slag soil.

[0059] The pH detector can be a slag soil acidity meter, which is composed of an electrode, a metal probe, and a functional value switching device. When the slag soil acidity meter is working, the metal probe is in contact with the slag soil, the potential difference between the two electrodes is measured, and the hydrogen ion concentration in the slag soil is calculated, and the pH value is calculated.

[0060] The slag soil humidity detector includes a slag soil humidity detector host 28 and a slag soil humidity detection probe 281. The slag soil humidity detector host 28 is arranged in the shell 21, and the lower end of the slag soil humidity detector is provided with the slag soil humidity detection probe 281, which extends below the bottom plate 22 through the bottom plate 22. Through this arrangement, the humidity of the soil can be directly detected.

[0061] The detection of the slag soil moisture detector on the moisture content of the slag soil can use a frequency domain reflection method (FDR technology), which utilizes the characteristics of electromagnetic wave propagation in the slag soil, when the electromagnetic wave propagates in the dry slag soil, due to the friction and damping effect between the slag soil particles, the propagation speed of the electromagnetic wave is fast, and when the slag soil contains water, the presence of water increases the dielectric constant of the slag soil, thereby reducing the propagation speed of the electromagnetic wave.

[0062] The detection assembly of the slag soil rapid detection probe needs to be connected to the displacement driving device before use, and the connection lines of the XRF detector, the PID detector, the position sensor, the pH value detector and the slag soil moisture detector are connected with the external power supply and the data acquisition equipment respectively. When detecting, the displacement driving device drives the detection assembly to move above the slag car, and then 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 soil moisture detector below the mounting plate of the detection assembly are inserted into the slag soil to be detected, the depth of the inserted soil is detected by the position sensor, when the predetermined insertion depth is reached, the displacement driving device stops descending, the content of heavy metals, VOCs gas content, pH value and humidity data in the slag soil are detected by the XRF detector, the PID detector, the pH value detector and the slag soil moisture detector respectively, and the detected data is transmitted to the data acquisition equipment; after the detection is completed, the displacement driving device drives the detection assembly to leave the slag soil and returns 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 soil moisture detector are inserted into the slag soil to be detected by the displacement driving device, if hard objects such as stones are encountered, the resistance is large, the relative sliding of the sliding block on the sliding seat assembly and the sliding connection 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 soil moisture detector, preventing damage; the reset members arranged on the front and rear sides of the sliding connection seat can automatically reset the relative displacement of the sliding block and the sliding connection seat, so that the positional relationship between the two is kept stable, and the steel wire rope arranged between the upper and lower connecting seats can limit the relative movement range between the upper and lower connecting seats, preventing the sliding block from being separated from the sliding connection seat.

[0063] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
