Description

Technical Field

[0001] The utility model relates to the technical field of dust environment detection, in particular to a dust environment detection device. Background Art

[0002] The dust environment detection device is an instrument used to monitor the dust concentration in the environment. It is widely used in industrial production, mining, construction sites and other fields. Its main principle is to sense the dust particles in the environment through sensors or instruments, and convert the measurement results into digital signals, so as to achieve real-time monitoring and alarm of dust concentration. The common dust environment detection device consists of a dust environment detection body, an air inlet pipe, a rubber hose, an air suction pipe, and a filter plate. The following shortcomings were found during use:

[0003] 1. After the air is sucked into the air intake pipe, the air will pass through the filter plate to filter out some impurities, and then enter the dust environment detection body through the air intake pipe for detection. When other filters are frequently performed, the impurities filtered out will usually block the filter plate and the air intake pipe, which can easily affect the dust in the gas to enter the dust environment detection body, thus affecting the detection results;

[0004] 2. Generally, rubber hoses are directly put on the air inlet pipe. If the position of the air intake pipe is moved, the rubber hose will also be moved, which will cause the connection between the rubber hose and the air inlet pipe to loosen easily, thus affecting the dust environment detection body to detect dust in the gas.

[0005] Therefore, in view of this, the existing structure is studied and improved, and a device for detecting dust environment is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is that when collecting dust in the gas, coarse impurities in the gas are likely to block the filter plate and the air intake pipe, and the rubber hose is likely to become loose when connected to the air intake pipe.

[0007] The technical solution adopted by the utility model is: a device for detecting a dust environment, comprising a dust environment detecting body and an air intake pipe arranged on one side of the dust environment detecting body, a rubber hose being movably sleeved on the air intake pipe, an end of the rubber hose away from the air intake pipe being rotatably connected with a filtering air intake assembly through a connecting ring thread, the filtering air intake assembly being composed of a filter box, a collecting frame, a cover body, a filter plate, and an air intake pipe, and the filtering air intake assembly is provided with a filter plate, a rubber hose, an air intake pipe, and a dust environment detecting body to prevent coarse impurities from clogging the filter plate, the rubber hose, the air intake pipe, and the dust environment detecting body, one side of the dust environment detecting body being provided with two fixing assemblies for fixing the rubber hose, and the two fixing assemblies being arranged on both sides of the air intake pipe.

[0008] As a further solution of the utility model: a handle is hingedly provided on the top of the dust environment detection body through two connecting blocks, and two foot pads are fixedly provided on the bottom of the dust environment detection body.

[0015] 1. The utility model sets a filter air intake assembly. When the gas is sucked from the air intake pipe, the coarse impurities can be filtered out through the filter plate. At the same time, the coarse impurities will enter the collection frame and the cover body due to gravity, thereby preventing the coarse impurities from clogging the filter box and the filter plate, so that the dust in the gas can smoothly enter the dust environment detection body for detection.

[0016] 2.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-2 A dust environment detection device includes a dust environment detection body 1 and an air intake pipe 101 arranged on one side of the dust environment detection body 1. A handle 102 is hingedly provided on the top of the dust environment detection body 1 through two connecting blocks to facilitate hand-carrying of the dust environment detection body 1. Two foot pads 103 are fixedly provided on the bottom of the dust environment detection body 1.

[0026] See also Figure 1 and Figure 4, a rubber hose 2 is movably sleeved on the air inlet pipe 101, and the end of the rubber hose 2 away from the air inlet pipe 101 is rotatably connected with a filter air inlet assembly 3 through a connecting ring thread, and the filter air inlet assembly 3 is composed of a filter box 301, a collection frame 302, a cover body 303, a filter plate 304, and an air intake pipe 305. The filter air inlet assembly 3 is provided with a filter plate 304, a rubber hose 2, the air inlet pipe 101, and a dust environment detection body 1 to prevent coarse impurities from blocking. The filter air inlet assembly 3 includes a filter box 301, and a collection frame 302 is fixedly provided at the bottom of the filter box 301. 2. A movable cover at the bottom of the collecting frame 302 is provided with a cover body 303, a filter plate 304 is provided in the cover body 303, the collecting frame 302, the cover body 303 and the filter plate 304 are tilted, a rubber ring is fixedly inlaid on the inner edge of the cover body 303, and the filter plate 304 is connected to the inner side of the cover body 303 by a plurality of bolts 1, and the cover body 303 is connected to the collecting frame 302 by a plurality of bolts 2, an air intake pipe 305 is fixedly provided on one side of the filter box 301, and the other side of the filter box 301 is rotatably connected with a connecting ring thread. The connecting ring is rotatably connected to the thread of the filter box 301, so that the filter box 301 and the rubber tube 2 can be disassembled and assembled. Since the collecting frame 302, the cover body 303 and the filter plate 304 are inclined, the coarse impurities can directly enter the collecting frame 302 and the cover body 303 after being filtered by the filter plate 304, thereby avoiding the coarse impurities from clogging the filter plate 304 and the filter box 301. The filter plate 304 and the cover body 303 are connected by bolt 1, so that the filter plate 304 can be replaced. The cover body 303 and the collecting frame 302 are connected by bolt 2, so that the cover body 303 and the collecting frame 302 can be disassembled and assembled, so as to clean the coarse impurities, the filter box 301 and the collecting frame 302.

[0027] See also Figure 1-3 One side of the dust environment detection body 1 is provided with two fixing components 4 for fixing the rubber tube 2, and the two fixing components 4 are arranged on both sides of the air intake pipe 101, the fixing component 4 includes a frame plate 401 fixedly arranged on one side of the dust environment detection body 1 and a fixing block 402 slidably arranged on one side of the dust environment detection body 1, a slider is arranged on the fixing block 402, and a sliding groove cooperating with the sliding of the slider is arranged on one side of the dust environment detection body 1, a threaded rod 403 is rotatably arranged on one side of the fixing block 402 through a bearing, and the threaded rod 403 threadably rotates through the frame plate 401, a threaded hole cooperating with the threaded rod 403 threadably rotates on the frame plate 401, and a handle 2 404 is fixedly arranged at one end of the threaded rod 403. Through the sliding connection between the slider and the slide groove, when the threaded rod 403 is rotated, the fixed block 402 will not rotate with the threaded rod 403. Since the threaded rod 403 is connected to the frame plate 401 by threaded rotation, when the threaded rod 403 is rotated, the threaded rod 403 can be moved on the frame plate 401, so that the position of the fixed block 402 can be adjusted. When the fixed blocks 402 on the two fixed components 4 clamp the rubber hose 2, the connection between the rubber hose 2 and the intake pipe 101 can be reinforced.

[0028] The working principle of this utility model:

[0029] When it is necessary to detect dust in the environment, first put the rubber hose 2 on the air inlet pipe 101, and then turn the handle 404 to drive the threaded rod 403 to rotate, so that the threaded rod 403 moves on the frame 401, thereby driving the fixed block 402 to move in the direction of the rubber hose 2, thereby clamping the rubber hose 2 and the air inlet pipe 101, and then the dust environment detection body 1 can be started, so that the gas in the environment is sucked into the filter box 301 of the filter air inlet assembly 3 through the suction pipe 305, and then the coarse impurities can be filtered out through the filter plate 304, so that the coarse impurities enter the collection frame 302 and the cover body 303, and the filtered gas will enter the dust environment detection body 1 from the air inlet pipe 101 through the rubber hose 2 for detection.

[0030] If it is necessary to clean the coarse impurities in the filter intake assembly 3, bolt 2 can be rotated so that the connection between the cover body 303 and the collection frame 302 is not fixed. At this time, the cover body 303 can be pulled off the collection frame 302 to discharge the coarse impurities. Then the filter box 301, the collection frame 302, the cover body 303, and the filter plate 304 can be cleaned.

[0031] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
