Description

Technical Field

[0001] This utility model belongs to the field of construction dust removal technology, and in particular relates to an environmentally friendly dust removal device for building construction. Background Technology

[0002] During construction, different types of work will generate dust of different particle sizes. For example, earthwork mainly produces fine dust, while the crushing of concrete blocks and stones will produce a large amount of larger dust particles, such as stone fragments.

[0003] To address the dust control needs at construction sites, various filtration devices exist in current technology. However, these devices generally use filter screens with fixed pore sizes for filtration, a design that has significant limitations:

[0004] (1) Existing filtration devices use filter screens with fixed apertures, which cannot be automatically adjusted according to the differences in dust particle size generated by different operations. Large dust particles can easily clog the filter screen, resulting in reduced ventilation and reduced filtration efficiency. For fine dust, the fixed filter screen has insufficient filtration precision.

[0005] (2) Some filtration equipment with multiple filters requires manual switching of filters, and the construction personnel may not be able to accurately judge the dust particle size and switch filters in a timely manner, resulting in poor filtration effect.

[0006] Therefore, there is a need for an automatically adaptable, efficient, and stable environmentally friendly dust removal device for construction to solve the above problems. Utility Model Content

[0007] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides an environmentally friendly dust removal device for construction. Based on the difference in impact force of particulate matter, it achieves graded filtration, automatically separating coarse and fine particles, effectively extending filter life and improving system stability. It monitors filter clogging status through air pressure changes in the lower cavity below the partition, enabling automatic alarms and resolving issues of untimely maintenance. The detachable bottom cover, combined with a latch design, allows for automatic dust discharge, making cleaning quick and convenient. This comprehensively solves the technical problems of easily damaged filters, difficult maintenance, and low cleaning efficiency in traditional dust removal equipment.

[0008] The technical solution adopted by this utility model is as follows: An environmentally friendly dust removal device for construction includes a main body box. A dust suction hole is provided through the top wall of the main body box. A partition plate is horizontally fixed inside the main body box. A partition plate is vertically fixed on the lower wall of the partition plate. A fine filter plate and a coarse filter plate are respectively hinged to both sides of the partition plate. An air inlet hole and an air inlet hole are provided through the partition plate. The air inlet hole corresponds to the fine filter plate, and the air inlet hole corresponds to the coarse filter plate. A particle identification and guiding component is provided on the inner wall of the top of the main body box. The particle identification and guiding component includes an inclined block hinged to the inner wall of the top of the main body box, a connecting rod hinged to the bottom wall of the inclined block, and a barrier plate horizontally slidably disposed on the upper wall of the partition plate. The upper wall of the barrier plate is hinged to the other end of the connecting rod.

[0009] As a preferred technical solution of this invention, a tension spring is fixedly provided on the inner wall of the main body box, and the tension spring is fixedly connected to the side wall of the barrier plate.

[0010] As a preferred technical solution of this invention, the bottom of the main body box is provided with a detachable bottom cover, the bottom cover is provided with a through air vent, and an air pump is fixedly provided on the lower wall of the bottom cover. The air pump is connected to the interior of the main body box through the air vent.

[0011] As a preferred technical solution of this invention, the main body box is provided with a pin inserted into the side wall for fixing the fine filter plate and the coarse filter plate.

[0012] As a preferred technical solution of this invention, a guide post is provided vertically and slidably through the bottom cover, a counterweight is fixedly provided at the lower end of the guide post, a touch switch is provided on the upper wall of the counterweight, an alarm is fixedly provided on the outer wall of the top of the main body box, and the touch switch is electrically connected to the alarm.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows:

[0014] (1) The graded filtration mechanism based on the difference in impact force of particulate matter can automatically separate coarse and fine particulate matter according to the size and kinetic energy of dust particles. Large dust particles have greater momentum and will trigger the linkage of the baffle plate when they hit the inclined block, and will be guided to the coarse filtration path for interception. Fine dust particles have less kinetic energy and will enter the fine filtration area along the preset channel. This effectively solves the wear and blockage problem caused by large dust particles impacting the filter screen in traditional equipment, and improves the filter screen life and the stability and efficiency of the dust removal system.

[0015] (2) The filter screen clogging status is monitored by the air pressure change in the cavity below the partition. When the filter screen is clogged, the alarm is automatically triggered, which solves the technical problem that the existing dust removal equipment cannot clean the clogged filter screen in time, resulting in a decrease in dust removal efficiency or the need for frequent manual inspection and maintenance.

[0016] (3) The bottom cover is detachable and the dust is automatically discharged after the pin is pulled out. When cleaning the filter screen, the dust is discharged quickly and conveniently, which solves the technical problems of complex operation and low efficiency of traditional dust removal equipment in cleaning the filter screen.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6As shown, an environmentally friendly dust removal device for construction includes a main body box 1. A bottom cover 20 is detachably mounted on the bottom of the main body box 1. An air outlet 4 is provided through the bottom cover 20. An air pump 2 is fixedly mounted on the lower wall of the bottom cover 20. The air pump 2 is connected to the interior of the main body box 1 through the air outlet 4. A guide column 18 is vertically slidably mounted through the bottom cover 20. A counterweight 16 is fixedly mounted at the lower end of the guide column 18. A touch switch 17 is mounted on the upper wall of the counterweight 16. An alarm 19 is fixedly mounted on the top outer wall of the main body box 1. The touch switch 17 is electrically connected to the alarm 19. A dust suction hole 3 is provided through the top wall of the main body box 1. A partition 6 is horizontally fixed inside the main body box 1. The lower wall of the partition 6 is vertically... A partition 2 7 is fixedly provided, with a fine filter plate 9 and a coarse filter plate 8 respectively hinged to both sides of the partition 2 7. An air inlet 14 and an air inlet 2 15 are provided through the partition 1 6. The air inlet 14 corresponds to the fine filter plate 9, and the air inlet 2 15 corresponds to the coarse filter plate 8. A particle identification and guiding component 21 is provided on the inner wall of the top of the main body box 1. The particle identification and guiding component 21 includes an inclined block 10 hinged to the inner wall of the top of the main body box 1, a connecting rod 11 hinged to the bottom wall of the inclined block 10, and a barrier plate 12 horizontally slidably provided on the upper wall of the partition 1 6. The upper wall of the barrier plate 12 is hinged to the other end of the connecting rod 11. A tension spring 13 is fixedly provided on the inner wall of the main body box 1, and the tension spring 13 is fixedly connected to the side wall of the barrier plate 12.

[0027] The main body box 1 is provided with a pin 5 inserted into the side wall for fixing the fine filter plate 9 and the coarse filter plate 8.

[0028] In actual use, first start the air pump 2. The dust-laden airflow is sucked into the main body box 1 through the dust suction hole 3. The dust particles in the airflow will collide and come into contact with the inclined surface of the inclined block 10.

[0029] For larger dust particles, the impact force will drive the inclined block 10 to rotate around its hinge axis (e.g. Figure 5 (As shown in the motion state), the rotation of the inclined block 10 transmits power through the connecting rod 11, thereby driving the baffle plate 12 to move to one side to block the air inlet 14. In this state, the air pump 2 will guide large dust particles through the air inlet 15 into the filtration path, where they will be initially intercepted and separated by the coarse filter plate 8, and finally the purified air will be discharged through the air outlet 4.

[0030] For smaller dust particles, due to their smaller impact force, the inclined block 10 will remain stationary and will not rotate. At this time, the baffle plate 12 will stably block the second air inlet 15 under the continuous action of the tension spring 13. The air pump 2 will guide the small dust particles through the first air inlet 14 into another filtration path, where they will be finely filtered by the fine filter plate 9. Similarly, the purified air will be discharged through the air outlet 4.

[0031] During continuous filtration, if the coarse filter plate 8 or the fine filter plate 9 becomes clogged, negative pressure will occur in the cavity below the partition 6. When the air pressure drops to the preset trigger threshold, the change in air pressure in the cavity will drive the counterweight 16 and the guide column 18 to move upward. At this time, the touch switch 17 will contact the bottom cover 20 and be triggered. The touch switch 17 will activate the alarm 19 to sound an alarm, reminding the operator that the filter screen has reached saturation and needs to be cleaned and maintained.

[0032] During cleaning, the bottom cover 20 must first be removed from the main body box 1, and then the pin 5 is pulled out. At this time, the dust accumulated on the upper side of the coarse filter plate 8 and the fine filter plate 9 is discharged from the bottom channel of the main body box 1, and the dust is collected or received.

[0033] In summary, if a person skilled in the art, inspired by this invention, designs a similar structure and embodiment without departing from the spirit of this invention, such design should fall within the protection scope of this invention.
