Description

Technical Field

[0001] This utility model relates to the field of cartridge dust collector technology, and in particular to a vertical cartridge dust collector. Background Technology

[0002] Cartridge dust collectors are environmental protection devices used to treat and filter dry dust, achieving the purpose of environmental protection. They are widely used in the food, pharmaceutical, metallurgy, building materials, cement, machinery, chemical and semiconductor industries for the purification of dust-laden gases and the recovery of dust materials.

[0003] Existing cartridge dust collectors generally utilize a burst of high-pressure compressed air to create a powerful reverse airflow, causing the cartridge to expand and contract at a high frequency, thereby shaking off the dust adhering to the outer surface of the cartridge. However, the high-pressure gas is often introduced from the top of the cartridge or a single location, resulting in uneven expansion of the cartridge. The area near the air inlet expands significantly, while the area away from the air inlet expands less, and there may even be areas that do not expand. This prevents the dust far from the air inlet from being effectively removed, resulting in long-term residue and affecting the use of the filter. Utility Model Content

[0004] Therefore, it is necessary to provide a vertically inserted cartridge dust collector to address the above problems.

[0005] A vertically inserted cartridge dust collector includes: a fixed frame, a dust collection hopper mounted on the fixed frame, a filter cover connected to the top of the dust collection hopper, a mounting frame fixedly connected inside the filter cover, a filter cartridge mounted on the mounting frame, and a cleaning mechanism provided inside the filter cover; the cleaning mechanism includes an air inlet pipe fixedly connected to the surface of the filter cover, one end of the air inlet pipe fixedly connected to an interface, multiple air delivery pipes evenly distributed inside the filter cover and connected to the air inlet pipe, a cleaning pipe rotatably connected to the surface of the air delivery pipes, multiple air outlet pipes evenly distributed on the surface of the cleaning pipes, a nozzle fixedly connected to the end of the air outlet pipes away from the cleaning pipes, and a valve installed on the air delivery pipes.

[0006] In one embodiment, the mounting bracket has a plurality of positioning holes evenly distributed on its surface, a positioning protrusion ring is fixedly connected to the bottom of the positioning hole, the outer surface of the positioning protrusion ring is provided with an external thread, the top of the filter cylinder is provided with an internal thread corresponding to the positioning protrusion, and the bottom of the mounting bracket is provided with a sealing ring corresponding to the filter cylinder.

[0007] In one embodiment, the cleaning tube is provided in a one-to-one correspondence with the positioning hole, the cleaning tube extends into the interior of the filter cylinder, and is coaxially arranged with the filter cylinder.

[0008] In one embodiment, the air outlet pipe is arc-shaped and does not contact the inner wall of the filter cartridge; the nozzle is a fan-shaped nozzle with the fan-shaped surface of the nozzle arranged vertically.

[0009] In one embodiment, the dust collection hopper is funnel-shaped, with an air inlet pipe connected to the upper part of the surface of the dust collection hopper, a drain valve at the bottom of the dust collection hopper, and an observation window on the surface of the dust collection hopper.

[0010] In one embodiment, a maintenance cover is rotatably connected to the surface of the filter cover, the maintenance cover being located on the side of the filter cover surface away from the air intake pipe.

[0011] In one embodiment, a fan is fixedly installed on the top of the filter cover, a motor is installed on the top of the fan, the output shaft of the motor is fixedly connected to the fan blades, the air outlet of the fan is connected to an air outlet pipe, and the air inlet of the fan is connected to the top of the filter cover.

[0012] In one embodiment, the nozzle includes a nozzle body and an angle adjustment sleeve. The nozzle body is fixedly connected to the air outlet pipe, and the angle adjustment sleeve is detachably connected to the nozzle body by threads. The surface of the angle adjustment sleeve is provided with spray nozzles of different fan-shaped angles.

[0013] Beneficial effects

[0014] 1. The above-mentioned vertical cartridge dust collector uses a cleaning pipe to drive the nozzle to rotate. Combined with the evenly distributed air outlet pipes and vertical fan-shaped nozzles, the high-pressure airflow covers the inner wall of the filter cartridge 360°, achieving uniform impact and avoiding dust residue caused by uneven local expansion. The lower cleaning air pressure can prevent excessive stretching of the filter cartridge, avoid cracking at the connection between the filter material and the end cap, and extend the filter cartridge life. The impact and vibration of the rotating jet airflow work together to improve the cleaning efficiency of sticky dust. Frequent shutdowns for manual cleaning are not required, ensuring continuous production.

[0015] 2. By changing the angle adjustment sleeve with different fan-shaped angles, it can adapt to dust with different characteristics. For highly viscous dust, a large angle adjustment sleeve is selected to expand the airflow coverage and avoid dust residue at the bottom; for coarse-sized dust, a small angle adjustment sleeve is selected to enhance the airflow impact force, ensure complete dust removal, and improve adaptability.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined with Figure 1 - Figure 5 This invention describes a vertically inserted cartridge dust collector.

[0026] In one embodiment, a vertical cartridge dust collector includes: a fixed frame 100, a dust collection hopper 200 mounted on the fixed frame 100, a filter cover 300 connected to the top of the dust collection hopper 200, a mounting frame 510 fixedly connected inside the filter cover 300, a filter cartridge 500 mounted on the mounting frame 510, and a cleaning mechanism 600 provided inside the filter cover 300; the cleaning mechanism 600 includes an air inlet pipe 610 fixedly connected to the surface of the filter cover 300, an interface 620 fixedly connected to one end of the air inlet pipe 610, a plurality of air delivery pipes 630 evenly distributed inside the filter cover 300 and connected to the air inlet pipe 610, a cleaning pipe 650 rotatably connected to the surface of the air delivery pipe 630, a plurality of air outlet pipes 660 evenly distributed on the surface of the cleaning pipe 650, a nozzle 670 fixedly connected to the end of the air outlet pipe 660 away from the cleaning pipe 650, and a valve 640 installed on the air delivery pipe 630.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, the mounting bracket 510 has multiple positioning holes 520 evenly distributed on its surface. A positioning protrusion ring is fixedly connected to the bottom of each positioning hole 520, and the outer surface of the positioning protrusion ring has an external thread. The top of the filter cylinder 500 has an internal thread corresponding to the positioning protrusion, and the bottom of the mounting bracket 510 has a sealing ring corresponding to the filter cylinder 500. A cleaning pipe 650 is provided corresponding to each positioning hole 520, extending into the interior of the filter cylinder 500 and coaxially with it. The air outlet pipe 660 is arc-shaped and does not contact the inner wall of the filter cylinder 500. The nozzle 670 is a fan-shaped nozzle with a vertically oriented fan-shaped surface. The nozzle 670 includes a nozzle body and an angle adjustment sleeve. The nozzle body is fixedly connected to the air outlet pipe 660, and the angle adjustment sleeve is detachably connected to the nozzle body via threads. The surface of the angle adjustment sleeve has spray nozzles with different fan-shaped angles.

[0028] In this embodiment, the positioning protrusion at the bottom of the positioning hole 520 precisely engages with the internal thread at the top of the filter cartridge 500, forming a sealed structure in conjunction with the sealing ring at the bottom of the mounting bracket 510. This effectively prevents dust-laden gas from leaking through the installation gap, improving the air filtration effect. The arc-shaped air outlet pipe 660 conforms to the curvature of the inner wall of the filter cartridge 500 while maintaining a gap to avoid movement interference. The vertically positioned fan-shaped nozzle 670 can cover the area along the height of the filter cartridge 500, improving the cleaning effect on the filter cartridge 500. By changing the angle adjustment sleeve, it can adapt to dust with different viscosities and particle sizes, preventing dust residue at the bottom of the filter cartridge 500. A sealed bearing is also provided at the rotating connection between the cleaning pipe 650 and the air supply pipe 630, in conjunction with a dustproof sealing ring, to prevent dust from inside the filter cover 300 from entering the rotation gap, ensuring smooth rotation of the cleaning pipe 650.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the dust collection hopper 200 is funnel-shaped, with an air inlet pipe 210 connected to the upper part of its surface. A drain valve is located at the bottom of the dust collection hopper 200, and an observation window is provided on its surface. A maintenance cover 310 is rotatably connected to the surface of the filter cover 300, located on the side of the filter cover 300 away from the air inlet pipe 610. A fan 420 is fixedly installed on the top of the filter cover 300, and a motor 430 is installed on the top of the fan 420. The output shaft of the motor 430 is fixedly connected to the blades of the fan 420. An air outlet pipe 410 is connected to the air outlet of the fan 420, and the air inlet of the fan 420 is connected to the top of the filter cover 300.

[0030] In this embodiment, the funnel-shaped dust collection hopper 200 guides coarse dust particles to quickly converge towards the bottom drain valve, preventing accumulation. Dust-laden gas entering the hopper can achieve pre-dust collection through airflow diffusion. Combined with the observation window on the surface of the dust collection hopper 200, the amount of dust accumulation can be monitored in real time. The inspection cover 310 is connected to the filter cover 300 via a hinge. When opened, it allows direct access to the filter cartridge 500 without disassembling other components, significantly simplifying the filter cartridge replacement process and reducing downtime. A protective cover 400 is installed on the top of the filter cover 300 to shield the fan 420 and motor 430.

[0031] Working principle: The motor 430 is started, which drives the fan 420 to run, creating a negative pressure inside the filter cover 300. The dust-laden gas enters the funnel-shaped dust collection hopper 200 through the inlet pipe 210. As the internal space of the dust collection hopper 200 expands, the airflow speed drops sharply. Coarse dust particles naturally settle to the bottom of the dust collection hopper 200 under the action of gravity. The fine dust particles that do not settle rise with the airflow and enter the filter cover 300. When passing through the filter material of the filter cylinder 500, the dust is intercepted on the outer surface of the filter cylinder 500. The clean gas passes through the filter material and enters the interior of the filter cylinder 500. It enters the fan 420 from the top of the mounting bracket 510 and is then discharged through the outlet pipe 410.

[0032] When the pressure difference between the inside and outside of the filter cartridge reaches the set value, the cleaning mechanism 600 is activated. An external high-pressure air source enters the air inlet pipe 610 through the interface 620. The valve 640 on the air supply pipe 630 is opened, and the high-pressure airflow enters the cleaning pipe 650. It is then delivered to the fan-shaped nozzle 670 through the arc-shaped air outlet pipe 660. When the nozzle 670 sprays airflow, it generates a reaction force, driving the cleaning pipe 650 to rotate around its own axis. Through the evenly distributed air outlet pipe 660 and the vertical fan-shaped nozzle 670, the airflow covers the inner wall of the filter cartridge 500 at a full height of 360°, achieving uniform impact and separating the dust from the filter cartridge 500 to prevent the filter cartridge 500 from clogging. The high-pressure airflow causes the filter cartridge 500 to vibrate slightly, and the dust layer on the outer surface is peeled off as a whole. Because the filter cartridge is arranged vertically, the dust falls into the dust collection hopper 200 under the action of gravity and is finally discharged by opening the drain valve.

[0033] It should be noted that the fan 420, motor 430, filter cartridge 500, valve 640, and sealed bearing mentioned above are all components with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the motor 430 and valve 640 can be powered by mains power. The specific power supply method can be selected according to the situation, which will not be elaborated here.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
