Description

Technical Field

[0001] This utility model relates to the field of filter cartridge dust collection technology, specifically a high-efficiency filter cartridge dust collection device. Background Technology

[0002] In industrial production processes, traditional cartridge dust collectors often employ single-layer filter screens or simple folded designs, resulting in limited filtration area. When dust-laden gas passes through, the filter screen cannot effectively and completely intercept dust, leading to low filtration efficiency. Furthermore, insufficient filtration causes severe wear and tear on downstream equipment, affecting the stability and lifespan of the entire production system. Additionally, dust accumulates on the surface of the filter cartridge in certain areas, increasing filtration resistance and reducing air permeability. As resistance increases, energy consumption rises significantly. Moreover, the filter cartridge is prone to damage due to prolonged exposure to high pressure, leading to more frequent replacements and increased maintenance costs and burden. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that traditional cartridge dust collection devices have limited filtration area due to the fact that the cartridges are mostly single-layer filter screens or simple folded designs, resulting in low filtration efficiency and serious equipment wear. This utility model provides a high-efficiency cartridge dust collection device.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A high-efficiency cartridge dust collection device includes an outdoor unit assembly. A discharge assembly is located at the bottom of the outdoor unit assembly, and an air inlet is located on the side wall of the discharge assembly. A flow guide hood and a filter assembly extend through the lower interior of the outdoor unit assembly. The bottom of the flow guide hood is located at the top of the discharge assembly, and the flow guide hood is located at the bottom of the filter assembly. An air outlet is located on the upper left side of the outdoor unit assembly, and a blower is located at the outer end of the air outlet. A pulse blowing assembly is located at the top interior of the outdoor unit assembly, and the bottom of the pulse blowing assembly is inclined around the outer side wall of the filter assembly. A dust collection box is located below the discharge assembly. A control panel is located on the front side of the outdoor unit assembly. The filter assembly includes a filter screen and double-layer folded flaps, with the filter screen located in the inner layer of the double-layer folded flaps.

[0006] Furthermore, the outdoor unit assembly includes a body, a top shell, and a support frame. The top end of the unloading assembly is fixedly connected to the bottom end of the body. The flow guide and the filter assembly both penetrate the interior of the body. The air outlet is located on the upper left side of the side wall of the body. The upper end of the pulse blowing assembly penetrates the interior of the top shell, and the lower end of the pulse blowing assembly penetrates the upper interior of the body.

[0007] Furthermore, the top shell is disposed at the top of the body, and the inner ring of the support frame is sleeved on the lower outer side of the body.

[0008] Furthermore, the unloading assembly includes an unloading funnel and a door. The air inlet is located on the side wall of the unloading funnel. The unloading funnel is located at the bottom of the outdoor unit assembly and the diversion hood. The door is located at the bottom of the unloading funnel. When the dust in the unloading funnel accumulates to a certain amount, the door is opened and the dust falls into the dust collection box below.

[0009] Furthermore, the filter assembly also includes a bottom ring and an upper ring. The bottom ring is disposed at the bottom end of the filter screen and the double-layer folded leaf, and the upper ring is disposed at the top end of the filter screen and the double-layer folded leaf. The double-layer folded leaf and the inner filter screen of the filter assembly significantly increase the filtration area.

[0010] Furthermore, the pulse blowing assembly includes a blow valve and a blow pipe. The blow valve is located at the top inside of the outdoor unit assembly. The bottom end of the side wall of the blow pipe is inclined towards the upper outer side of the filter assembly, so that compressed air impacts the filter cartridge surface at high speed and at an angle.

[0011] Furthermore, the blowpipe is located at the bottom end of the blow valve, and compressed air is ejected from the blowpipe after the blow valve is opened.

[0012] Compared with the prior art, this utility model provides a high-efficiency cartridge dust collection device, which has the following beneficial effects:

[0013] This high-efficiency cartridge dust collector significantly increases the filtration area by placing the filter screen of the filter assembly within the inner layer of the double-folded flaps. This allows for more thorough dust interception, improving filtration efficiency and purification effect. For dust removal, the pulse-blowing component is angled around the bottom of the filter assembly and positioned above the outer wall. When the blow valve is opened, the compressed air ejected from the blow pipe impacts the surface of the filter cartridge at a highly efficient angle and direction, generating an instantaneous reverse airflow. This causes the filter cartridge to expand, contract, and deform, more thoroughly shaking off the adhering dust. This ensures the filter cartridge maintains excellent filtration performance, extends its service life, and reduces replacement frequency and costs. Overall, it achieves the advantages of high-efficiency dust collection, stable operation, and easy maintenance. Attached Figure Description

[0021] 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. Example 1:

[0022] like Figures 1-6 As shown, a high-efficiency cartridge dust collection device includes an outdoor unit assembly 1, a discharge assembly 2 at the bottom of the outdoor unit assembly 1, an air inlet 3 at the side wall of the discharge assembly 2, a flow guide hood 4 and a filter assembly 5 passing through the lower interior of the outdoor unit assembly 1, the bottom of the flow guide hood 4 being located at the top of the discharge assembly 2 and the bottom of the filter assembly 5, an air outlet 6 at the upper left side of the outdoor unit assembly 1, an exhaust fan 7 at the outer end of the air outlet 6, a pulse blowing assembly 8 at the top interior of the outdoor unit assembly 1, the bottom of the pulse blowing assembly 8 being inclined around the upper outer wall of the filter assembly 5, a dust collection box 9 below the discharge assembly 2, and a control panel 10 at the front of the outdoor unit assembly 1.

[0023] like Figure 1As shown, the outdoor unit assembly 1 includes a body 11, a top shell 12, and a support frame 13. The top of the unloading assembly 2 is fixedly connected to the bottom of the body 11. The air intake hood 4 and the filter assembly 5 both penetrate the interior of the body 11. The air outlet 6 is located on the upper left side of the side wall of the body 11. The upper end of the pulse blowing assembly 8 penetrates the interior of the top shell 12, and the lower end of the pulse blowing assembly 8 penetrates the upper interior of the body 11. The top shell 12 is located at the top of the body 11, and the inner ring of the support frame 13 is fitted onto the lower outer side of the body 11.

[0024] like Figure 2 As shown, the unloading assembly 2 includes an unloading funnel 21 and a door 22. The air inlet 3 is located on the side wall of the unloading funnel 21. The unloading funnel 21 is located at the bottom of the outdoor unit assembly 1 and the diversion hood 4. The door 22 is located at the bottom of the unloading funnel 21. Dust-laden gas enters the device from the air inlet 3 on the side wall of the unloading funnel 21 of the unloading assembly 2. The unloading funnel 21 has a structure that is wider at the top and narrower at the bottom.

[0025] like Figure 4 As shown, the filter assembly 5 includes a filter screen 52 and a double-layer folded leaf 53. The filter screen 52 is disposed in the inner layer of the double-layer folded leaf 53. The filter assembly 5 also includes a bottom ring 51 and an upper ring 54. The bottom ring 51 is disposed at the bottom end of the filter screen 52 and the double-layer folded leaf 53, and the upper ring 54 is disposed at the top end of the filter screen 52 and the double-layer folded leaf 53. The double-layer folded leaf 53 and the inner filter screen 52 of the filter assembly 5 greatly increase the filtration area. When dust-laden gas passes through the filter cartridge, the dust is intercepted on the outer surface of the filter cartridge. Example 2:

[0026] like Figures 5-6 As shown, the pulse blowing assembly 8 includes a blow valve 81 and a blow pipe 82. The blow valve 81 is located at the top of the interior of the outdoor unit assembly 1. The bottom end of the side wall of the blow pipe 82 is inclined towards the upper outer side of the filter assembly 5. The blow pipe 82 is located at the bottom end of the blow valve 81. A signal is transmitted to the blow valve 81 of the pulse blowing assembly 8 to open it. After the blow valve 81 is opened, compressed air is sprayed out from the blow pipe 82. The bottom end of the side wall of the blow pipe 82 is inclined towards the upper outer side of the filter assembly 5.

[0027] Working principle: such as Figures 1-6 As shown, the dust-laden gas enters and is guided: The dust-laden gas enters the device through the air inlet 3 on the side wall of the unloading funnel 21 of the unloading assembly 2. Since the unloading funnel 21 has a structure that is wider at the top and narrower at the bottom, it can initially gather the dust-laden gas. Subsequently, the gas enters the guiding hood 4, which guides the dust-laden gas to flow upward, so that it flows evenly to the filter assembly 5, avoiding the airflow directly impacting the filter cartridge and ensuring the stability of the filtration process.

[0028] Filtration and purification: Under the guidance of the hood 4, the dust-laden gas reaches the filter assembly 5. The double-layer folded leaf 53 and the inner filter screen 52 of the filter assembly 5 greatly increase the filtration area. When the dust-laden gas passes through the filter cartridge, the dust is intercepted on the outer surface of the filter cartridge, while the clean gas passes through the filter cartridge and enters its interior.

[0029] Pulse cleaning: The control panel 10 sends a pulse signal according to a preset time interval or filter resistance value. The signal is transmitted to the blow valve 81 of the pulse blowing assembly 8, causing it to open. After the blow valve 81 opens, compressed air is ejected from the blow pipe 82. The bottom end of the side wall of the blow pipe 82 is tilted towards the outer upper side of the filter assembly 5, causing the compressed air to impact the surface of the filter cartridge at high speed and at an angle, generating an instantaneous reverse airflow. Under the action of the reverse airflow, the filter cartridge expands and contracts, causing the dust adhering to the inner surface of the filter cartridge to fall off and fall into the discharge funnel 21 below.

[0030] Dust collection and unloading: Dust falling off the filter cartridge falls into the unloading funnel 21 under gravity. When the dust in the unloading funnel 21 accumulates to a certain amount, the box door 22 is opened, and the dust falls into the dust collection box 9 below, realizing the collection and centralized treatment of dust.

[0031] Clean gas is discharged; the clean gas purified by the filter cartridge flows upward to the air outlet 6 on the upper left side of the side wall of the machine body 11. The exhaust fan 7 is installed at the outer end of the air outlet 6 to provide power for the gas flow and discharge the purified clean gas from the device, completing the entire dust collection and purification process. The operator can control the device through the control panel 10.
