Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a protective mechanism for the air inlet of a dust collector. Background Technology

[0002] In the field of dust removal equipment, the design of the air inlet protection mechanism directly affects the equipment's operating efficiency and service life. Traditional dust collector air inlets typically adopt a straight-through duct structure, and their protection measures mainly rely on a single insect-proof net. This has the following technical defects: most existing technologies prevent mosquitoes from entering through physical barriers and do not integrate active mosquito control functions. When mosquitoes gather near the air inlet, they may enter the duct through gaps in the insect-proof net and breed inside the equipment, creating a hygiene hazard. Therefore, an air inlet protection mechanism for dust collectors has been proposed to solve the above problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The purpose of this invention is to address the problem that most existing technologies prevent mosquitoes from entering through physical barriers without integrating active mosquito-killing functions. When mosquitoes gather near the air inlet, they may enter the pipe through the gaps in the insect-proof net and breed inside the equipment, creating a hygiene hazard. Therefore, this invention proposes an air inlet protection mechanism for dust collectors.

An air inlet is provided at the top of the spiral-shaped air inlet duct, and an air outlet is provided at the rear end of the spiral-shaped air inlet duct. Stainless steel insect-proof mesh is threadedly connected to the inner side of both the air inlet and the air outlet. An insect-killing mechanism is provided on the inner side of the spiral-shaped air inlet duct. An arc-shaped cover plate is detachably connected to the bottom end of the spiral-shaped air inlet duct by bolts, and the arc-shaped cover plate fits tightly against the bottom end of the spiral-shaped air inlet duct.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the embodiments, by Figure 1-3Provided is an air inlet protection mechanism for a dust collector, comprising a spiral air inlet duct 1, with brackets 2 detachably connected to both the front and rear ends of the spiral air inlet duct 1 by bolts, an air inlet 3 at the top of the spiral air inlet duct 1, an air outlet 4 at the rear end of the spiral air inlet duct 1, stainless steel insect-proof mesh 5 threadedly connected to the inner sides of both the air inlet 3 and the air outlet 4, an insect-killing mechanism 6 provided on the inner side of the spiral air inlet duct 1, and an arc-shaped cover plate 7 detachably connected to the bottom end of the spiral air inlet duct 1 by bolts, the arc-shaped cover plate 7 being tightly fitted to the bottom end of the spiral air inlet duct 1.

[0022] With the above setup, the air outlet 4 connects to the air inlet of the dust collector. When insects carried by the air enter the duct through the air inlet 3 or the air outlet 4, they are first blocked by the inner stainless steel insect-proof mesh 5. The mesh size is smaller than that of common insects (such as mosquitoes, flies, moths, etc.), achieving efficient physical isolation. Small insects that are not blocked enter the volute-shaped air inlet duct 1 and are attracted and killed by the insect-killing mechanism 6. The insect-killing mechanism 6 works continuously to ensure that invading insects cannot survive or enter the dust collector through the duct. Dead insects and the remains of blocked insects naturally fall to the bottom of the volute-shaped duct. Operators periodically remove the arc-shaped cover 7 to quickly clean up the accumulation. To prevent insect carcasses from clogging the air ducts or rotting and breeding bacteria, both the air inlet 3 and the air outlet 4 are equipped with stainless steel insect screens 5. This not only prevents external insects from entering but also blocks insects from escaping from inside the dust collector (especially when the machine is stopped). The combination of physical interception (stainless steel insect screen 5) and active extermination (insect extermination mechanism 6) significantly reduces the probability of insects entering the dust collection system. The stainless steel insect screen 5 has a threaded connection design, making it easy to disassemble, clean, or replace clogged / damaged stainless steel insect screens 5, ensuring ventilation efficiency. The bolt connection method allows for tool-free disassembly, and the arc-shaped cover 7 allows for quick cleaning, greatly shortening the cleaning cycle and reducing downtime.

[0023] Reference Figure 1-3 The insect-killing mechanism 6 includes an insect-killing frame 61, the inner side of the spiral air inlet duct 1 is detachably connected to the insect-killing frame 61, the inner side of the insect-killing frame 61 is fixedly connected to the insect-killing net 62, and the right end of the insect-killing frame 61 is provided with an insect-attracting lamp 63.

[0024] With the above structural setup, the insect-attracting lamp 63 releases a specific spectrum (such as 365nm ultraviolet light) to actively attract phototactic insects (moths, mosquitoes, flies, etc.) to the insect-killing frame area. The insect-killing net 62 is energized to form a high-voltage grid, instantly killing the insects that come into contact with it. The dead insects fall due to gravity and accumulate at the bottom of the spiral duct. Maintenance personnel can remove the arc-shaped cover 7 to clean it up, avoiding accumulation that may affect airflow or hygiene. The insect-killing frame 61 is detachable, allowing for quick replacement of damaged insect-killing net 62 or insect-attracting lamp 63 without shutting down the entire duct.

[0025] Reference Figure 1-3Among them, the inner side of the spiral air inlet duct 1 is fixedly connected to two fixing plates 8, and the opposite side of the two fixing plates 8 is provided with a slot 9, and the insect-killing net 62 is snapped into the inner side of the two slots 9.

[0026] With the above structural setup, the edge of the insect-killing net 62 is embedded in the slots 9 of the two fixing plates 8, and the slots 9 achieve lateral locking to prevent displacement caused by airflow impact.

[0027] Reference Figure 1-3 In this case, the bottom ends of the two brackets 2 are fixedly connected to support plates 10, and the two support plates 10 are provided with several mounting holes 11.

[0028] With the above structural design, several mounting holes 11 (distributed in a matrix) are opened on the double support plate 10 to accommodate different fixing methods such as anchor bolts, chemical anchors, and expansion bolts.

[0029] Reference Figure 1-3 Among them, the top end of the spiral air inlet duct 1 is fixedly connected to two hanging rings 12;

[0030] With the above structural design, two hanging rings 12 can be used to hoist the spiral air inlet duct 1 during installation.
