Description

Technical Field

[0001] The invention relates to the field of rapid detection of solid waste pollution, and in particular to a mobile rapid screening device for slag pollution. 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, and has promulgated and implemented a large number of soil pollution prevention and control regulations. Therefore, the rapid pollution screening technology of waste is an important control means to respond to national environmental protection policies, strengthen the pre-management of waste treatment, and prevent pollution before it happens.

[0003] In the prior art, the detection of slag is usually carried out by setting a slag sampling device on the gantry or on a robotic arm, and then setting a slag detection component on the gantry or at a predetermined position, and moving the sampled slag to the slag detection component for detection, or moving the slag detection component next to the sampling component to detect the sampled slag. After the detection is completed, the slag is moved to a slag recovery box, or pushed out of the sampling device to return the slag to the slag truck.

[0004] The latest online slag detection system is the "Slag Sampling and Detection System for Slag Trucks" disclosed in the patent with publication number CN115615739A previously applied by the applicant (with the same inventor as the present invention). The 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 assembly 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.

[0005] The main problems of the system currently include: 1) During the inspection, the moving range of the slag detection system is limited, and the slag transport vehicle must drive to the inspection platform for inspection; 2) During the inspection, the sample must be collected first, then moved to the inspection component, and then inspected. After the inspection is completed, the slag must be moved to the slag sampling collection container, which has low inspection efficiency and takes a long time; 3) The slag detection system has a complex structure, which includes a large number of robotic arms and servo motors and other equipment. The cost is very high, the control is complex, the inspection equipment is not fully integrated, and the possibility of mechanical failure in the process of each inspection equipment moving to the inspection position is increased; 4) When the soil moisture is too high, it is difficult for the sampling component to obtain enough samples, which may make it impossible to complete the inspection work. Summary of the invention

[0006] The purpose of the present invention is to provide a mobile rapid screening device for slag pollution in view of the problems existing in the slag detection system described in the background technology.

Through this setting, when the XRF drill bit and the detection drill bit of the slag quick inspection component are inserted into the slag, if they encounter stones and other objects and generate large resistance, the detection component can slide relative to the displacement drive device to form a buffer to prevent damage to the XRF drill bit and the detection drill bit.

When the slag quick inspection assembly is conducting slag inspection, when the XRF drill bit of the XRF detector and the detection drill bit of the PID detector are inserted into the slag, if there are hard objects such as stones in the slag and the resistance is large, the relative sliding between the sliding connection seat and the slider can buffer the resistance and prevent damage to the XRF drill bit of the XRF detector and the detection drill bit of the PID detector. When the slider and the sliding connection seat slide relatively, the tension springs of the two sets of reset parts can be used to elastically reset the sliding connection seat, so that the position between the slider and the sliding connection seat is restored to the initial state.

[0035] The lifting seat 4 is used to install the rapid detection component 5. The structure of the lifting seat 4 can be designed as needed. For example, the lifting seat 4 can be designed as a flange plate, and the flange plate is fixedly connected to the lifting movable member 34 on the lifting drive component 3. As a preferred solution, a shell can also be provided on the lifting seat 4, and the upper components of the rapid detection component 5 are arranged in the shell, as long as the XRF drill bit, the detection drill bit, and the detection probe of the rapid detection component 5 are arranged below the shell.

[0036] like Figure 5 and 6 As shown, the quick test assembly 5 includes a housing 51, an XRF detector and a PID detector.

[0037] The housing 51 includes a cylindrical barrel and a bottom plate 52, the bottom plate 52 is fixedly connected to the bottom of the cylindrical barrel, and the bottom plate 52 is preferably fixedly connected to the cylindrical barrel in a detachable manner. The XRF detector host 54 and the PID detector host 55 are respectively fixedly connected to the bottom plate 52, and a connecting portion is provided at the top of the cylindrical barrel, and the connecting portion is used to connect the lifting seat 4.

[0038] A plurality of position sensors 59 are provided on the outer wall of the housing 51. The position sensors 59 are used to detect the depth of the XRF drill bit 541 of the XRF detector and the detection drill bit 551 of the PID detector inserted into the slag. By providing the position sensors 59, the depth of the XRF drill bit 541 of the XRF detector and the detection drill bit 551 of the PID detector inserted into the slag can meet the detection requirements.

[0039] The XRF detector includes an XRF detector host 54 and an XRF drill bit 541 . The XRF detector host 54 is disposed in a housing 51 of the quick detection component 5 and fixed on a bottom plate 52 . The XRF drill bit 541 is fixedly connected below the bottom plate 52 .

[0040] The XRF detector host 54 includes an XRF protective cover, an X-ray module and a semiconductor detector. The XRF protective cover is fixedly connected to the bottom plate of the shell of the rapid detection component. The X-ray module and the semiconductor detector are fixedly arranged in the XRF protective cover. The X-ray module is used to emit X-rays, and the semiconductor detector is used to receive secondary rays reflected from the slag. The heavy metal content in the slag can be calculated by the processor through analysis and calculation of the emitted X-rays and the received secondary rays.

[0041] The XRF drill bit 541 includes a cylindrical portion and a conical portion, the conical portion is fixedly connected to the lower end of the cylindrical portion, a reflective lens for changing the direction of the X-ray is provided in the cylindrical portion, an X-ray outlet is provided on the side wall of the cylindrical portion, and the position of the X-ray outlet corresponds to the reflective lens.

The XRF detector host obtains the value of the heavy metal content in the slag by analyzing and calculating the received reflected rays.

[0042] The working principle of the XRF detector is: when the atoms of heavy metal elements contained in the slag sample are irradiated by high-energy X-rays, they emit a characteristic X-ray spectrum with a certain energy, and the energy of the characteristic X-ray spectrum is measured by a semiconductor detector 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 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 the simultaneous measurement of multiple elements, and qualitative and quantitative analysis can be performed by detecting the energy positions and intensities of different characteristic X-rays.

[0043] The PID detector includes a PID detector host 55 and a detection drill bit 551 .

[0044] A vertical fixed base plate is provided on the bottom plate 52 of the shell of the quick test component 5, and the PID detector host 55 is fixedly connected to the fixed base plate. The connection method can be selected according to needs. For example, a semicircular clamp is used to fix the PID detector host 55 on the fixed base plate.

[0046] The working principle of the PID detector 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 "ppm" or "ppb" concentration values. 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 test results, so the content of VOCs gas in the slag can be accurately detected.

[0047] like Figure 6As shown, as a preferred solution, a pH value detector and a slag humidity detector can also be arranged in the housing 51. The pH value detector host 56 and the slag humidity detector host 57 are arranged in the housing 51, and the lower ends of the pH value detector and the slag humidity detector are respectively provided with detection probes 58, which pass through the through holes on the bottom plate 52 and extend to the bottom of the bottom plate 52. By arranging the pH value detector and the slag humidity detector, when the slag is detected, the pH value and humidity of the slag can be detected, so that the data detected by the quick detection component 5 is more complete; the detection probe 58 is arranged below the bottom plate 52, and the detection probe 58 can be directly inserted into the slag for detection during detection, so that the detection efficiency is higher and the detection result is more accurate.

Through this arrangement, the slider 62 and the sliding connection seat 63 can slide relative to each other. When the quick inspection component 5 is performing slag detection, when the XRF drill bit of the XRF detector and the detection drill bit of the PID detector are inserted into the slag, if there are hard objects such as stones in the slag and the resistance is large, the relative sliding between the sliding connection seat 63 and the slider 62 can buffer the resistance and prevent damage to the XRF drill bit 541 of the XRF detector and the detection drill bit 551 of the PID detector. When the slider 62 and the sliding connection seat 63 slide relative to each other, the tension spring 65 of the two sets of reset members can be used to elastically reset the sliding connection seat 63, so that the position between the slider 62 and the sliding connection seat 63 is restored to the initial state.

A wire rope 68 is connected between the movable bolt 67 on the upper connection seat 61 and the corresponding movable bolt 67 on the lower connection seat 64. By providing the movable bolt 67 and the wire rope 68, the upper connection seat 61 and the lower connection seat 64 of the sliding connection seat 63 can be connected through the movable bolt 67 and the wire rope 68, so that the two are kept in a connected state, and the slider 62 is prevented from being separated from the sliding connection seat 63.

[0056] Before using the mobile rapid screening device for slag pollution of the present invention, it is necessary to first connect the rapid testing component to the mobile device according to the aforementioned method, and the connecting lines of the XRF detector, PID detector, position sensor, pH detector and slag moisture detector must be connected to the controller respectively, and the controller is connected to the power supply and data acquisition equipment and data display equipment. During the inspection, the mobile device drives to the side of the slag transport vehicle that needs to be inspected, controls the quick inspection component on the mobile device to move to the top of the slag on the slag transport vehicle through the controller, and then drives the quick inspection component to descend through the lifting drive component, so that the detection drill bit of the PID detector, the detection head of the XRF detector, and the detection probes of the pH value detector and the slag humidity detector under the bottom plate of the quick inspection component are inserted into the slag to be inspected, and the depth of insertion into the soil is detected by the position sensor. When the predetermined insertion depth is reached, the descent is stopped, and the heavy metal content, VOCs gas content, pH value and humidity data in the slag are respectively detected by the XRF detector, PID detector, pH value detector and slag humidity detector, and the detected data are transmitted to the controller, and then transmitted to the data acquisition device and the data display device; after the inspection is completed, the mobile device drives the quick inspection component to rise and leave the slag, and the mobile device moves to the next slag transport vehicle that needs to be inspected, and the slag is inspected according to the above method. 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 mobile 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.
