Technical Field
[0001] This utility model relates to the field of environmental monitoring device technology, specifically to an environmental monitoring device for dusty environments. Background Technology
[0002] In environmental monitoring devices for dusty environments, filters are key components for purifying dust-laden airflow. They must intercept fine dust particles that water mist cannot capture, preventing clean airflow from carrying dust out. However, in dusty environments, filters are prone to clogging due to rapid dust accumulation, requiring frequent disassembly and replacement to maintain purification efficiency.
[0003] Existing filters often use a fixed connection structure, requiring the disassembly of multiple components, which is cumbersome and time-consuming. Current filters are typically connected to the inner wall of the purification chamber via bolts, welding, or multiple sets of nested clips. Disassembly requires first removing the purification chamber cover and loosening the bolts, or individually releasing the nested clips. Some devices also require removing peripheral components such as the annular spray head and suction fan duct before accessing the filter. This complex connection structure results in a significant time commitment for each disassembly, especially in scenarios with frequent replacements, which greatly extends equipment downtime, interrupts detection and purification operations, and reduces overall work efficiency. Furthermore, repeated disassembly of bolts can easily lead to stripping, and welded structures cannot be repeatedly disassembled and reassembled, further increasing maintenance costs. Utility Model Content
[0004] The purpose of this utility model is to provide an environmental monitoring device for dusty environments, addressing the issues raised in the background art. Existing devices often employ fixed connection structures for their filters, requiring the disassembly of multiple components, resulting in cumbersome and time-consuming operations. These filters are typically connected to the inner wall of the purification chamber via bolts, welding, or multiple sets of nested clips. Disassembly requires removing the purification chamber cover, loosening the bolts, or individually releasing the nested clips. Some devices also require removing peripheral components such as the annular spray head and suction fan duct before accessing the filter. This complex connection structure leads to significant time consumption for each disassembly, especially in high-frequency replacement scenarios, drastically extending equipment downtime, interrupting monitoring and purification operations, and reducing overall work efficiency. Furthermore, repeated bolt disassembly can cause stripping, and welded structures cannot be repeatedly disassembled and reassembled, further increasing maintenance costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmental detection device for dusty environments, comprising a base, a rotating seat on the top of the base, a detection box fixedly installed on one side of the top of the rotating seat, a display screen fixedly installed on the top of the detection box, a detection head fixedly installed on the top inside the detection box, a signal line from the top of the detection head extending to the outside of the detection box and connected to the display screen, a collection tube connected to one side of the detection box, an inlet tube connected to one side of the collection tube, a purification box fixedly installed on the other side of the top of the rotating seat, an annular spray head fixedly installed near the top inside the purification box, inner seats fixedly connected to the top of both sides of the purification box, and a moving groove formed at the center of opposite ends of the two inner seats on the left and right sides, and the front side of the purification box... A filter screen is provided, with its rear end passing through the purification box and two movable slots and slidably connected to them. Slide rails are provided at the center of the top and bottom of each movable slot. Rollers are movably mounted on both sides of the top and bottom of the filter screen. The side of the rollers away from the filter screen passes through the interior of the slide rails and slidably connects to them. Fixing slots are provided on both sides of the filter screen. Outer panels are provided on both sides of the purification box. Fixing rods are fixedly connected to the opposite ends of the two outer panels. The side of the fixing rods away from the outer panels passes through the purification box, the inner seat, and the fixing slots and engages with them. A water tank is fixedly installed on the top of the purification box. A water pump is fixedly installed at the bottom of the water tank. The output end of the water pump passes through the purification box and the filter screen and connects to one side of the top of the annular spray head.
[0006] Compared with the prior art, the beneficial effects of this utility model are: This environmental monitoring device for dusty environments features an inner seat fixedly connected to both sides of the purification chamber near the top, with a movable groove at one end of the center. The rear end of the filter screen passes through the purification chamber and slides into the movable groove, forming a preliminary position. Simultaneously, outer plates on both sides of the purification chamber are connected to the inner seat via fixing rods, engaging with the fixing grooves on both sides of the filter screen for secure fixation. This structure eliminates the need for bolts or welding; disassembly and assembly only require operating the outer plates and fixing rods, without disassembling peripheral components such as the annular spray head or the air inlet pipe of the second suction fan. This directly avoids the cumbersome operation caused by disassembling peripheral components, laying the foundation for rapid disassembly and assembly. To remove the filter screen, simply pull the outer plates on both sides of the purification chamber outwards, causing the fixing rods to move from the fixing grooves of the filter screen into the inner seat. The filter screen is then pulled out of the purification chamber to release its fixed constraints. Next, the filter screen is pulled forward. The pulleys mounted on the top and bottom sides of the filter screen slide along the slide rails at the top and bottom centers of the inner seat's moving groove. This converts the sliding friction between the filter screen and the moving groove into rolling friction, significantly reducing pulling resistance and allowing the filter screen to be quickly pulled out from the front of the purification chamber. For reinstallation, simply align the rear end of the filter screen with the moving groove and push it in. The pulleys will slide along the slide rails to guide the filter screen into precise position. Then, push the outer plate to engage the fixing rod in the fixing groove. The entire disassembly and assembly process requires no complex tools, significantly reducing the time required for each operation. This method is suitable for high-frequency replacement scenarios in high-concentration dust environments, preventing prolonged downtime due to filter screen replacement, ensuring continuous testing and purification operations, and improving overall work efficiency.

A slide rail 26 is provided at the center of the top and bottom of the slide rail 24. The top and bottom sides of the filter screen 19 are equipped with pulleys 27. The side of the pulley 27 away from the filter screen 19 passes through the interior of the slide rail 26 and is slidably connected to the slide rail 26. The filter screen 19 is provided with fixing grooves 25 on both sides. The two sides of the purification box 12 are provided with outer plates 28. The opposite ends of the two outer plates 28 are fixedly connected with fixing rods 29. The side of the fixing rods 29 away from the outer plates 28 passes through the purification box 12, the inner seat 23 and the fixing grooves 25 in sequence and is engaged with the fixing grooves 25. A water tank 13 is fixedly installed on the top of the purification box 12. A water pump is fixedly installed at the bottom of the water tank 13. The output end of the water pump passes through the purification box 12 and the filter screen 19 in sequence and is connected to one side of the top of the annular spray head 18.
[0011] The bottom of the rotating base 3 is rotatably connected to the top of the base 1, and a handle 17 is fixedly connected to one side of the rotating base 3.
[0012] The four sides of the bottom of the base 1 are equipped with casters 2.
[0013] A filter plate 7 is snapped onto one side of the collection tube 5. The top of the filter plate 7 extends through the outside of the collection tube 5 and is fixedly connected to a pull plate 8. A control valve is movably mounted on the other side of the collection tube 5.
[0014] A suction fan 11 is fixedly installed on the other side of the test box 4. The input end of the suction fan 11 is connected to the other side of the test box 4, and the output end of the suction fan 11 is connected to the exhaust pipe 14. One side of the exhaust pipe 14 is connected to the bottom of the purification box 12.
[0015] A second suction fan 20 is fixedly installed on the top side of the other side of the purification box 12. The input end of the second suction fan 20 is connected to an air inlet pipe 21, and one side of the air inlet pipe 21 is connected to the purification box 12. The output end of the second suction fan 20 is connected to an air outlet pipe 22.
[0016] A waste collection tray 15 is movably installed at the bottom of the purification box 12. A waste outlet pipe connected to one side of the waste collection tray 15 extends to the outside of the purification box 12. A control button 16 is fixedly installed on the other side of the purification box 12 near the center.
[0017] Working principle: The universal wheels 2, which are movable on all four sides of the base 1, are pushed to move the device to the target dust detection area. The rotating base 3 is rotated by the handle 17 fixedly connected to one side, adjusting the orientation of the collection pipe 5 and the inlet pipe 6 connected to one side of the detection box 4. The inlet pipe 6 is aligned with the direction of the airflow to be detected, completing the detection angle positioning. The installation status of the filter screen 19 inside the purification box 12 is checked: It is confirmed that the rear end of the filter screen 19 penetrates the purification box 12 and is slidably connected to the moving groove 24 of the inner seat 23, and that the fixing rods 29 of the outer plates 28 on both sides of the purification box 12 penetrate the purification box 12 and the inner seat 23 and are engaged with the fixing groove 25 of the filter screen 19, ensuring the filter screen 19 is securely fixed. Simultaneously, the engagement of the collection pipe 5 on one side is checked. Check if filter plate 7 is in place to prepare for subsequent testing and purification; open the control valve mounted on the other side of the collection tube 5, allowing dust-laden airflow from the dusty environment to enter the collection tube 5 through the inlet pipe 6; filter plate 7 inside the collection tube 5 intercepts large dust particles in the airflow, reducing the total amount of dust entering the detection chamber 4 and preventing excessive dust adhesion from affecting the detection accuracy. After the dust-laden airflow enters the detection chamber 4, the detection head 10 fixedly installed at the top of the detection chamber 4 detects the dust concentration. The detection data is transmitted through the signal line at the top of the detection head 10 to the display screen 9 fixedly installed at the top of the detection chamber 4, realizing the visualization of dust concentration; after the detection is completed, close the control valve to block external airflow from entering the collection tube 5; through the other side of the purification chamber 12... The control button 16, fixedly installed near the center, starts the suction fan 11, fixedly installed on the other side of the detection box 4. The suction fan 11 generates negative pressure at its input end, adsorbing residual dust from the inner wall of the detection box 4, the surface of the detection head 10, and the inside of the collection tube 5. The residual dust is then transported to the bottom side of the purification box 12 through the exhaust pipe 14 connected to the output end of the suction fan 11. At this point, the water pump at the bottom of the water tank 13, fixedly installed at the top of the purification box 12, is started. The water pump pressurizes the water in the water tank 13 and transports it through the output pipe to the annular spray head 18, fixedly installed at the top of the purification box 12. The annular spray head 18 sprays water mist, which condenses with the dust particles in the dust-laden airflow to form liquid dirt, which falls into the purification box 12. The sludge is collected in the bottom movable receiving tray 15. The second suction fan 20, which is fixedly installed on the other side of the purification box 12 near the top, is started. The input end of the second suction fan 20 draws in the airflow treated with water mist through the connected air inlet pipe 21. The airflow rises and passes through the filter screen 19 (located below the annular spray head 18). The filter screen 19 intercepts fine dust particles that are not captured by the water mist. The purified clean airflow is discharged from the purification box 12 through the air outlet pipe 22 connected to the output end of the second suction fan 20. When the filter screen 19 needs to be replaced due to dust accumulation, the outer plates 28 on both sides of the purification box 12 are pulled outward, which drives the fixing rod 29 to be pulled out from the fixing groove 25, inner seat 23 and purification box 12 of the filter screen 19, releasing the fixing constraint on the filter screen 19.Pull the filter screen 19 forward. The pulleys 27, which are movable at the top and bottom of the filter screen 19, slide along the slide rails 26 at the top and bottom center of the inner seat 23's moving groove 24, pulling the filter screen 19 out from the front of the purification box 12, completing the disassembly. Take a new or cleaned filter screen 19, align its rear end with the moving groove 24 in the purification box 12, and push it in. The pulleys 27 slide along the slide rails 26 to guide the filter screen 19 into precise position. Push the outer plate 28 inward, so that the fixing rod 29 passes through the purification box 12 and the inner seat 23 in sequence and is locked into the fixing groove 25 of the filter screen 19, completing the stable fixation of the filter screen 19, and the purification operation can be resumed. Periodically, discharge the liquid waste collected in the sludge collection tray 15 through the sludge outlet pipe that runs from one side of the sludge collection tray 15 to the outside of the purification box 12. If the filter plate 7 in the collection pipe 5 is blocked, remove it for cleaning or replacement through the pull plate 8 fixedly connected to the top of the filter plate 7 to ensure that the device can continuously perform dust detection and purification operations.
[0018] In summary, this environmental monitoring device for dusty environments features an inner seat 23 fixedly connected to both sides of the purification chamber 12 near the top, with a moving groove 24 at one end of its center. The rear end of the filter screen 19 penetrates the purification chamber 12 and slides through the moving groove 24, forming a preliminary positioning. Simultaneously, the outer plates 28 on both sides of the purification chamber 12, via fixing rods 29, penetrate the purification chamber 12 and the inner seat 23, engaging with the fixing grooves 25 on both sides of the filter screen 19 to achieve a stable fixation. This structure eliminates the need for bolts or welding; during assembly and disassembly, only the outer plates 28 and fixing rods 29 need to be operated, without disassembling peripheral components such as the annular spray head 18 and the air inlet pipe 21 of the second suction fan 20. This directly avoids the cumbersome operation caused by disassembling peripheral components, laying the foundation for rapid assembly and disassembly. When disassembling the filter screen 19, only the outer plates 28 on both sides of the purification chamber 12 need to be pulled outwards, causing the fixing rods 29 to move from the fixed position of the filter screen 19. The filter screen 19 is pulled out from the fixed slot 25, inner seat 23, and purification box 12, releasing the fixed constraints. Then, the filter screen 19 is pulled forward. The pulleys 27, which are movably mounted on the top and bottom sides of the filter screen 19, slide along the slide rails 26 opened at the top and bottom center of the inner seat 23 moving slot 24. This converts the sliding friction between the filter screen 19 and the moving slot 24 into rolling friction, greatly reducing the pulling resistance. This allows the filter screen 19 to be quickly pulled out from the front of the purification box 12. When reinstalling, simply align the rear end of the filter screen 19 with the moving slot 24 and push it in. The pulleys 27 slide along the slide rails 26 to guide the filter screen 19 into precise position. Then, push the outer plate 28 to make the fixing rod 29 snap into the fixed slot 25. The entire disassembly and assembly process does not require complicated tools, and the single operation time is greatly shortened. It can be adapted to high-frequency replacement scenarios in high-concentration dust environments, avoiding long-term downtime of the equipment due to filter screen 19 replacement, ensuring continuous detection and purification operations, and improving overall work efficiency.
