Description

Technical Field

[0001] The utility model relates to the technical field of dust simulation devices, in particular to an environmental dust simulation device. Background Art

[0002] During the use of mechanical equipment, it is sometimes necessary to use it in extreme environments with a lot of dust. Before leaving the factory, the equipment needs to be placed in a professional dust environment simulation area for simulated use. At this time, it is necessary to use it in conjunction with an environmental dust simulation device for simulated use.

[0003] In actual work, the structure and function of the environmental dust simulation device in the prior art are relatively complete and can basically meet the needs of daily use, but there are still the following two problems:

[0004] 1. In actual use, sand and dust will be mixed in the air duct during simulation, and then the sand and dust will be dispersed in the air under the action of the blower for simulation. However, during the sand feeding process, some sand may adhere to the external moisture and condense into blocks, which will cause the large sand to be unable to be blown away during the dust raising process, and then gather in the air duct and cause blockage;

[0005] 2. If you use filtering to filter large particles, long-term use will cause large particles to accumulate on the filter, causing the filter to be blocked and affecting the filtering effect.

[0006] Therefore, the utility model provides an environmental dust simulation device. Utility Model Content

[0015] As a preferred embodiment, an annular clamping frame is fixedly connected to one side of the outer surface of the air duct, a second annular clamping block is clamped on the inner wall of the annular clamping frame, and a funnel frame is fixedly connected to one side of the outer surface of the second annular clamping block.

[0028] like Figure 1-Figure 4As shown, this embodiment provides a technical solution: an environmental dust simulation device, comprising an installation frame 1, a blower 2 is fixedly installed on one side of the outer surface of the installation frame 1, an air duct 3 is fixedly installed on the output end of the blower 2, the air duct 3 is fixedly installed on the inner wall of the installation frame 1, a sand inlet pipe 4 is fixedly installed on the top of the outer surface of the air duct 3, and the sand inlet pipe 4 is installed on the top inner wall of the installation frame 1; an anti-blocking sand inlet structure 5 is provided on the top of the outer surface of the sand inlet pipe 4; an auxiliary dust structure 6 is provided on one side of the outer surface of the air duct 3; the anti-blocking sand inlet structure 5 comprises an annular groove 51, the annular groove 51 is opened on the top of the outer surface of the sand inlet pipe 4, the inner wall of the annular groove 51 is clamped with a first annular clamping block 54, the outer surface top of the first annular clamping block 54 is fixedly connected with a sand inlet circular frame 511, the inner wall of the sand inlet circular frame 511 is fixedly connected with a sand filter net 512, By setting the first annular clamping block 54 and the annular clamping groove 51, the sand inlet circular frame 511 and the sand inlet pipe 4 can be auxiliaryly fixed, so that the sand filter net 512 inside the sand inlet circular frame 511 can filter the large particles in the sand and dust, thereby avoiding accumulation and blockage inside the air duct 3. Under the action of the transmission gear 518 and the outer gear ring block 515, the brush plate 519 can be driven to rotate, so that the brush plate 519 can sweep the large particles of sand and dust filtered by the sand filter net 512 to avoid accumulation and blockage. At the same time, under the action of the second annular clamping block 63 and the annular clamping frame 61, the funnel frame 64 can be installed, so that when performing dust simulation, the range of wind direction is increased, thereby expanding the range of dust, increasing the dust coverage area, and making the dust simulation more realistic.

[0029] Further, such as Figure 2-Figure 3As shown: a rectangular connecting block 55 is fixedly connected to one side of the outer surface of the sand inlet circular frame 511, a rectangular clamping block 56 is fixedly connected to the bottom of the outer surface of the rectangular connecting block 55, a rectangular clamping frame 52 is fixedly connected to one side of the outer surface of the sand inlet pipe 4, the rectangular clamping block 56 can be clamped into the inner wall of the rectangular clamping frame 52, a threaded clamping rod 53 is inserted into one side of the outer surface of the rectangular clamping frame 52, a threaded clamping hole 57 is opened on one side of the outer surface of the rectangular clamping block 56, the threaded clamping rod 53 and the threaded clamping hole 57 are detachably threadedly connected, a U-shaped frame 58 is fixedly connected to the top of the outer surface of the rectangular connecting block 55, a driving motor 59 is fixedly installed on the top of the inner wall of the U-shaped frame 58, a transmission rod 510 is fixedly connected to the output end of the driving motor 59, and a transmission gear 518 is fixedly connected to the top of the outer surface of the transmission rod 510.

[0031] The above solution also has the problem that the second annular block 63 and the annular frame 61 are unstable to install and are easy to rotate and separate.

[0032] Working principle:

[0033] like Figure 1-4 As shown:

[0034] When in use: the first annular clamping block 54 is fixed to the annular clamping groove 51, and the threaded clamping rod 53 and the threaded clamping hole 57 are rotated and fixed, and the rectangular clamping block 56 can be clamped into the inner wall of the rectangular clamping frame 52, thereby fixing the sand inlet circular frame 511 and the sand inlet pipe 4;

[0035] At this time, the driving motor 59 is started, so that the driving motor 59 can drive the transmission rod 510 to rotate, and then drive the transmission gear 518 to rotate, and then drive the outer gear ring block 515 to rotate, so that the sliding round rod 514 can slide on the inner wall of the annular slide groove 513, and then drive the connecting round rod 517 and the brush plate 519 to rotate, so that the large particles of impurities on the top of the sand filter 512 are cleaned;

[0036] At this time, the second annular clamping block 63 is clamped into the inner wall of the annular clamping frame 61, and the threaded rod 65 can be inserted into the inner wall of the round through hole 62. At this time, the fixing nut 66 and the threaded rod 65 are fixed. At this time, the funnel frame 64 can diffuse the wind and sand blown out from the inside of the air duct 3, thereby increasing the diffusion range of the wind and sand.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
