Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a detection device for manganese and its compounds in the workplace. Background Technology

[0002] Manganese is a common metallic element widely used in industrial production. However, excessive manganese and its compounds in the workplace pose potential health hazards. Long-term exposure to high concentrations of manganese can damage the nervous and respiratory systems. For example, it can easily lead to nervous system dysfunction, causing symptoms similar to Parkinson's disease, such as tremors, muscle stiffness, and bradykinesia. It can also easily cause respiratory inflammation, posing a serious threat to workers' health.

[0003] A search revealed Chinese Patent Publication No. CN212693720U, which discloses a detection device for manganese and its compounds in workplace air. The device includes a base with casters fixedly installed around its four sides. The base has four internal grooves, each containing a drive rod extending outwards from the base. The output shaft of the drive rod is fixedly mounted with a movable seat. This detection device, equipped with drive rods, allows for easy measurement of manganese and its compounds at different heights. Activating the four drive rods causes the device to rise or fall via the movable seat, thus measuring the manganese and its compounds at various heights. The drive rods and casters facilitate easy movement and measurement of manganese and its compounds at different locations, resulting in sufficiently accurate measurements.

[0004] The aforementioned patent specification mentions that "by equipping the device with electric push rods, when it is necessary to measure the content of manganese and its compounds in the air at different heights, four electric push rods are activated to drive the detection device body to rise or fall via the movable seat, thereby measuring the content of manganese and its compounds in the air at various heights. The addition of push rods and casters makes the overall movement convenient, facilitating the measurement of the content of manganese and its compounds in the air at different locations, and ensuring that the measurement results are sufficiently accurate." While the above-mentioned device can measure manganese and its compounds in the air, it still faces challenges in terms of sensitivity, specificity, and stability. Therefore, a detection device for manganese and its compounds in the workplace is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a detection device for manganese and its compounds in the workplace, aiming to improve the problem that some existing devices are unable to effectively filter and transport manganese and its compounds in the workplace to subsequent processing stages, making it difficult to accurately identify trace levels of manganese and its derivatives.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detection device for manganese and its compounds in the workplace includes a housing, a connecting pipe fixedly connected inside the housing, a sampling mechanism at one end of the connecting pipe, and a maintenance mechanism on the outside of the housing. The sampling mechanism includes an air inlet pipe, which is fixedly connected to the outside of the connecting pipe. An exhaust pump head is fixedly connected inside the air inlet pipe, a first sealing ring is fixedly connected inside the air inlet pipe, a filter screen is fixedly connected to the outside of the first sealing ring, a second sealing ring is fixedly connected to the outside of the filter screen, a connecting port is threaded onto the outside of the air inlet pipe, a placement rack is fixedly connected to the bottom of the air inlet pipe, a processing component is fixedly connected to the other end of the connecting pipe, a heating component is fixedly connected to the other end of the processing component, and a scanning component is fixedly connected to the other end of the heating component.

[0008] The above technical solution works as follows: During testing, the exhaust pump head is activated, drawing in workplace gas through the intake pipe. The gas passes through a filter screen, where sealing rings one and two maintain a seal. After preliminary filtration, the gas enters the connecting pipe. Next, the gas enters the processing component for pretreatment to meet testing requirements. The treated gas then enters the heating component, which heats the gas and changes its state to facilitate subsequent testing. Finally, the heated gas enters the scanning component, which scans and detects manganese and its compounds in the gas to obtain the test results. The placement rack provides stable support for the intake pipe, and the connection port can be used to connect external equipment for auxiliary sampling.

Multiple mounting plates are threadedly connected to the bottom side of the outside of the housing, and an outer pipe plate is fixedly connected to the adjacent side of the mounting plates.

[0011] The above technical solution allows for the following: When the testing device requires maintenance, the rear cabinet door is rotated to open around the rotating connection with the housing, exposing the rear space of the housing. By unscrewing the threaded connector on the outer panel of the chassis, it is disengaged from the slot on the top side of the housing, opening the top maintenance space. The threaded connection of the mounting plate is then unscrewed, and the outer pipe plate is removed, enabling maintenance operations on the bottom of the housing and the internal pipes.

A support frame is fixedly connected to the outside of the fine-pore chamber. A gas supply pipe is fixedly connected to the bottom of the fine-pore chamber, and a second gas supply pipe is fixedly connected to the top of the fine-pore chamber.

[0017] The above technical solution involves the gas entering the fine-hole chamber through a connecting pipe, where it is processed through fine holes. The processed gas is then output through two gas supply pipes, with one part being output through the first pipe and the other part through the second pipe. The support frame ensures the stable operation of the fine-hole chamber.

[0019] The heating assembly includes a heating chamber, the heating chamber is fixedly connected to the other end of the first gas supply pipe, the heating chamber is fixedly connected to the other end of the second gas supply pipe, a support frame is fixedly connected to the outside of the heating chamber, a catalyst tube is fixedly connected to the outside of the heating chamber, and a transmission pipe is fixedly connected to the top of the heating chamber.

[0020] Through the above technical solution: gas from gas pipeline one and gas pipeline two enters the heating chamber, the catalyst tube releases the catalyst, the gas is heated in the heating chamber, the treated gas is output through the transmission pipe, and the support frame two maintains the stable operation of the heating chamber.

[0021] As a further description of the above technical solution:

[0022] The scanning assembly includes a probe chamber, the outside of which is fixedly connected to the other end of the transmission tube, a support base is fixedly connected to the bottom of the probe chamber, and scanners are fixedly connected to both ends of the probe chamber.

[0023] The above technical solution involves the gas output through the transmission tube entering the probe chamber, the support base maintaining the stability of the chamber, and the scanners at both ends scanning and detecting the gas inside the probe chamber to obtain relevant data on manganese and its compounds in the gas.

[0024] As a further description of the above technical solution:

[0026] Through the above technical solution, the processing data of the fine-pore chamber and the heating chamber, as well as the detection data of the scanner, are transmitted to the computer, which then receives and integrates this data.

[0027] As a further description of the above technical solution:

[0028] The first support frame is externally fixedly connected to the inside of the housing, the second support frame is externally fixedly connected to the inside of the housing, and the bottom of the support base is fixedly connected to the bottom side of the inside of the housing.

[0029] Through the above technical solution, support frame one, support frame two and support base are fixed to the corresponding positions inside the shell, providing stable support for the fine hole chamber, heating chamber and probe chamber.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, a negative pressure is generated by starting the exhaust pump head, which draws in the gas in the workplace through the intake pipe. The filter screen inside the intake pipe intercepts large particulate impurities. Sealing ring one and sealing ring two ensure the sealing of each connection of the intake pipe. The connection port enhances the gas intake efficiency. The gas after preliminary filtration is carried into the processing component through the connecting pipe. The processed gas is then transported to the heating component and finally enters the scanning component. This achieves effective filtration of manganese and its compounds in the workplace and delivers them to subsequent processing stages, achieving higher detection sensitivity and accuracy. This allows even trace amounts of manganese and its derivatives to be accurately identified without missing any details.

[0032] 2. In this utility model, the rear cabinet door rotates on the housing, and is positioned and installed by the slot thread on the outer panel of the chassis and the housing. The mounting plate and the thread of the outer panel of the pipe are installed on the outside of the housing. This not only ensures the closed protection of the outer shell when the device is running, but also allows it to be quickly opened during maintenance, making it convenient for operators to go deep into the device for inspection and maintenance. This solves the problem of device operation safety and maintenance convenience, and facilitates the smooth progress of later cleaning, maintenance and replacement of consumable parts.

[0047] Reference Figure 1 and Figure 3 The processing component 38 includes a fine-pore chamber 381, which further filters and separates the incoming gas, removing tiny particles and impurities. The gas passes through the fine-pore chamber 381 and traps impurity particles to achieve preliminary separation. The outside of the fine-pore chamber 381 is fixedly connected to the other end of the connecting pipe 2. A support frame 382 is fixedly connected to the outside of the fine-pore chamber 381. The support frame 382 provides support for the fine-pore chamber 381 and ensures its stability inside the device. A gas supply pipe 383 is fixedly connected to the bottom of the fine-pore chamber 381. The gas supply pipe 383 transports the gas processed by the fine-pore chamber 381 from one end to the heating component 39. A gas supply pipe 384 is fixedly connected to the top of the fine-pore chamber 381. The gas supply pipe 384 transports the gas processed by the fine-pore chamber 381 from one end to the heating component 39.

[0048] Specifically, the core component of the processing assembly 38 is the fine-pore chamber 381, which is connected to the end of the connecting pipe 2. Through the internal fine-pore structure, it filters and separates tiny particles and impurities in the gas. The fine-pore chamber 381 is provided with a support frame 382 on the outside to ensure its stability in the device. The gas supply pipes 383 at the bottom and 384 at the top work together to transport the processed gas to the heating assembly 39, ensuring that the gas can smoothly enter the next detection process.

[0049] Heating assembly 39 includes heating chamber 391, which heats the incoming gas and adds a catalyst to promote the chemical reaction of manganese and its compounds. Under constant temperature control, the remaining mixture flows over the catalyst surface to accelerate the cracking reaction and release pure group molecules. The heating chamber 391 is fixedly connected to the other end of gas supply pipe 383 and gas supply pipe 384. A support frame 392 is fixedly connected to the outside of heating chamber 391 to provide support for heating chamber 391 and ensure its stability inside the device.

A transmission tube 394 is fixedly connected to the top of heating chamber 391 to transport the heated gas to scanning assembly 310 for detection.

[0050] Specifically, the heating component 39 has a heating chamber 391 as its main body, and its two sides are connected to the first gas supply pipe 383 and the second gas supply pipe 384 respectively to receive gas from the processing component 38. The second support frame 392 set outside the heating chamber 391 maintains its stability in the device. The catalyst pipe 393 is fixedly connected to its exterior and is used to add catalyst into the heating chamber 391. Inside the heating chamber 391, the gas is heated and reacts with the catalyst. The top transmission pipe 394 is responsible for transporting the processed gas to the scanning component 310 to complete the further detection process.

[0051] The scanning assembly 310 includes a probe chamber 3101, which provides a working space for the scanner 3103 and concentrates and guides the gas for easy scanning and detection. It contains an internal sensitive probe array. The probe chamber 3101 is fixedly connected to the other end of the transmission tube 394. A support base 3102 is fixedly connected to the bottom of the probe chamber 3101 to provide support for the probe chamber 3101 and ensure its stability inside the device. The scanner 3103 is fixedly connected to both ends of the probe chamber 3101. The scanner 3103 performs excitation signal scanning tests on the area outside the probe chamber 3101 to confirm whether there is any residual target component.

[0052] Specifically, one end of the probe chamber 3101 of the scanning component 310 is connected to the transmission tube 394 to receive the heated gas. The interior of the probe chamber 3101 is responsible for the centralized guidance of the gas and providing working space for the scanner 3103. The support base 3102 at the bottom of the probe chamber 3101 ensures its stability. The scanner 3103, which is fixed at both ends of the exterior, detects the residual status of the target component by performing excitation signal scanning tests on a specific area outside the chamber, thereby completing the final gas detection process.

[0054] Specifically, the receiving end of computer 5 is connected to the output ends of scanner 3103, heating chamber 391, and fine hole chamber 381 respectively, and is used to receive data generated during the detection and processing of each component. At the same time, the support frame 382 supporting fine hole chamber 381, the support frame 392 supporting heating chamber 391, and the support base 3102 supporting probe chamber 3101 are fixed inside, inside and bottom of housing 1 respectively, providing stable support for the corresponding components and ensuring that each component maintains a stable operating state within the device.

[0055] Working principle: The exhaust pump head 32 generates negative pressure when it starts, which draws in the gas in the workplace through the intake pipe 31. The filter screen 34 inside the intake pipe 31 intercepts large particles of impurities. The sealing ring 33 and the sealing ring 35 respectively ensure the sealing between the intake pipe 31 and the filter screen 34 and between the intake pipe 31 and the connection port 36. The connection port 36 enhances the air intake efficiency of the intake pipe 31. The placement frame 37 provides support for the intake pipe 31. Subsequently, the gas that has undergone preliminary filtration is transported to the processing component 38 through the connecting pipe 2. In the processing component 38, the gas enters the fine pore chamber 381. The fine pore structure further filters and separates small particles and impurities. The support frame 382 ensures the stability of the fine pore chamber 381. The processed gas is transported to the heating component 39 through the gas delivery pipe 383 and the gas delivery pipe 384.

[0056] Gas enters the heating chamber 391 of the heating assembly 39, and the support frame 392 provides support for it. The catalyst tube 393 adds a catalyst to the heating chamber 391 to accelerate the chemical reaction of manganese and its compounds in the gas. After heating and catalytic reaction, the gas is transported to the scanning assembly 310 through the transmission tube 394. In the scanning assembly 310, the gas enters the probe chamber 3101 to form a stable airflow. The support seat 3102 ensures the stability of the probe chamber 3101. The scanner 3103 emits specific rays or signals to interact with manganese and its compounds in the gas, acquires relevant data, and transmits it to the computer 5.

[0057] Computer 5 receives data transmitted from scanner 3103, heating chamber 391 and fine-hole chamber 381, analyzes and calculates the final test result, and then transmits the result to display device 4 for visualization. Maintenance mechanism 6 plays a protective role when the device is working normally. The rear cabinet door 61 can be rotated and opened to facilitate the operator to inspect and maintain the inside of the device. The outer panel 62 of the chassis is fixed to the top side of the shell 1 by threaded connection. The slot 63 is used for installation and positioning. The mounting plate 65 fixes the outer panel 64 of the pipe to the shell 1 to protect the internal pipe.
