Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 5 shown, the present utility model provides a dust removal device for construction engineering construction, including a dust collector 1. A dust suction and filtration component 4 is arranged above the dust collector 1. A limit pipe 2 is movably sleeved inside the dust suction and filtration component 4. The lower end of the limit pipe 2 penetrates through the dust suction and filtration component 4 and is fixedly connected to the dust collector 1. A cleaning component 3 is arranged at the upper end of the limit pipe 2. The cleaning component 3 is slidably clamped inside the dust suction and filtration component 4;

[0025] The dust suction and filtration component 4 includes two dust suction heads 41 that are movably installed on the front and rear sides of the limit pipe 2 and are buckled with each other. A plurality of uniformly distributed filtration grooves 43 are formed on the surface of the dust suction head 41. The filtration grooves 43 are communicated with the dust collector 1 through the dust suction head 41 and the limit pipe 2;

[0026] The cleaning component 3 includes a guide groove 31 formed at the top of the inner cavity of the limit pipe 2 and a limit dust scraping rack 32 that is threadedly sleeved on the outer surface of the upper end of the limit pipe 2. The top of the limit dust scraping rack 32 is an inclined surface. The extension line of the inclined surface at the top of the limit dust scraping rack 32 coincides with the extension line of the top surface of the guide groove 31. The limit dust scraping rack 32 is slidably clamped inside the filtration groove 43; Due to the setting of the dust suction and filtration component 4, with the cooperation of the limit pipe 2, the dust collector 1 can conveniently absorb dust at different heights in the surrounding air. And due to the support of the positioning spring 7, the dust attached to the filtration groove 43 can be conveniently and quickly cleaned by the limit dust scraping rack 32, achieving the effect of ensuring the dust fluidity.

[0027] Among them, the outer peripheral diameter dimension of the limit dust scraping frame 32 is the same as that of the dust suction head 41, and the top view cross-sectional dimension of the outer surface of the limit dust scraping frame 32 is adapted to the top view cross-sectional dimension of the inner cavity of the filter tank 43.

[0028] Among them, a waterproof cap 42 is integrally formed at the top of the dust suction head 41, and the two waterproof caps 42 are buckled with each other.

[0029] Among them, upper and lower fastening blocks 44 are fixedly connected to the adjacent ends of the two dust suction heads 41, and the two dust suction heads 41 are fixedly connected through the fastening blocks 44 and the bolts inside them; due to the setting of the fastening blocks 44, it is convenient for the staff to disassemble and assemble the two dust suction heads 41 from the front and back, so as to facilitate the replacement of different dust suction and filtration components 4, so as to achieve the effect of assisting the dust collector 1 and the limit pipe 2 to remove dust of different specifications.

[0030] Among them, an adjusting thread 5 is arranged at the lower end of the outer surface of the limit pipe 2, and an adjusting ring 6 is movably sleeved outside the limit pipe 2. The adjusting ring 6 is connected to the limit pipe 2 through the adjusting thread 5; due to the setting of the adjusting thread 5, rotating the adjusting ring 6 can drive the lower end of the positioning spring 7 to move up and down slowly and stably under the cooperation of the adjusting thread 5; and the setting of the positioning ring 8 can limit the rising height of the adjusting ring 6 to avoid the situation that the adjusting ring 6 disengages from the adjusting thread 5.

[0031] Among them, a positioning spring 7 is arranged at the upper end of the outer surface of the limit pipe 2, and a positioning ring 8 located at the top of the adjusting ring 6 is also fixedly sleeved on the surface of the limit pipe 2. The outer peripheral diameter dimension of the positioning ring 8 is smaller than the inner diameter dimension of the positioning spring 7; due to the setting of the positioning spring 7, it can not only make the dust suction and filtration component 4 rise and reset after the staff moves down the dust suction and filtration component 4 to scrape off the attached dust, but also facilitate the staff to change the height of the lower end of the positioning spring 7 under the cooperation of the adjusting thread 5 and the adjusting ring 6, ensure that different dust suction and filtration components 4 are pushed to the highest position, and at the same time will not generate too much resistance to the staff when moving down the dust suction and filtration component 4.

[0032] The working principle and usage process of the present utility model:

[0033] As shown in the figure, assemble the equipment. According to the size of the dust removal particles and the spatial height where the dust is mainly dispersed, replace the appropriate dust suction and filtration component 4 and the cleaning component 3, that is, unscrew the bolts in the upper and lower fastening blocks 44 of the front and rear dust suction heads 41 to release the connection between the two dust suction heads 41, then unscrew the limit dust scraping frame 32 to replace a new limit dust scraping frame 32, and then install the new dust suction and filtration component 4, that is, buckle the two dust suction heads 41 front and back, and ensure that they are clamped outside the limit dust scraping frame 32, and then screw the bolts tightly into the fastening blocks 44.

[0034] After using for a period of time, dust will adhere to the inner wall surface of the filter tank 43, resulting in a reduction in the flow efficiency of the filter tank 43, which greatly affects the dust removal effect of the dust collector 1. At this time, hold the dust suction and filtration assembly 4 and move it downward, then the limit dust scraping frame 32 can move up and down relative to the inner wall of the filter tank 43, so that the top inclined surface thereof can scrape the dust on the inner wall of the filter tank 43, and the dust will slide along the top inclined surface of the limit dust scraping frame 32 and the guide groove 31 into the limit pipe 2, and finally fall into the dust collector 1;

[0035] After releasing the dust suction and filtration assembly 4, under the action of the elastic force recovery of the positioning spring 7, due to the support of the adjusting ring 6 on the lower end of the positioning spring 7, the elastic force recovery action can push the dust suction and filtration assembly 4 upward, so that it rises and gradually resets;

[0036] Since the weight of the newly replaced dust suction and filtration assembly 4 is different from that of the previous dust suction and filtration assembly 4, the pressure on the positioning spring 7 is different, resulting in different deformation degrees of the positioning spring 7. To ensure that the filter tank 43 is as much as possible at the upper end of the limit dust scraping frame 32 to improve the dust flow efficiency and promote the dust removal rate, it is necessary to ensure that the top of the positioning spring 7 always abuts against the bottom of the dust suction and filtration assembly 4 and has an elastic force intensity greater than the gravity of the dust suction and filtration assembly 4. Therefore, after replacing the new dust suction and filtration assembly 4, it is necessary to rotate the adjusting ring 6 in cooperation with the adjusting thread 5, and then move the adjusting ring 6 up and down, so that the lower end of the positioning spring 7 moves up and down, and the elastic force intensity of the positioning spring 7 can be changed.

[0037] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
