Description

Technical Field

[0001] The invention relates to the technical field of filling down, in particular to a filter cartridge dust collector provided with an amplifier. Background Art

[0002] The down filling room is a factory building specially used for producing down products such as down jackets and down quilts. It fills the down evenly into the inside of the clothing through mechanical vibration and airflow blowing to ensure the warmth and comfort of the down jacket. The down filling room is equipped with various equipment, such as down filling machines, sealing machines, down beating machines, etc., which are used to complete the processing of down products. During the down filling process in the down filling room, the down is prone to accidentally fall on the floor of the down filling room to form dust and dirt. Therefore, a filter cartridge dust collector is needed to treat it. After searching, it is found that the filter cartridge dust collector device in the prior art is typically an improvement of the filter cartridge dust collector with publication number CN102553365A, which is characterized in that a rigid non-compression eccentric rotating interference pressing piece is used to press the air outlet end face of the filter cartridge and the suspension orifice plate, and there is a buffer space of not less than 30 cm between the bottom of the filter cartridge and the bottom of the filter cartridge box, and the filter air inlet is arranged in the lower buffer space of the filter cartridge. Its main feature is that it can ensure that there are no oversize particles in the filtered gas, effectively protect the filter material from damage and extend the service life of the filter cartridge, and completely solve the two major shortcomings that are difficult to overcome in the filter cartridge dust collector. The effective service life of the filter cartridge is increased from the original maximum of 12 months to 18 months. The frame filter with a higher filtration accuracy than the lower filter cartridge is connected above the filter cartridge outlet by connecting the transition section interval, forming a two-level filtration connected in series between the upper and lower parts, with a minimum filtration accuracy of 0.1 micron. It is used in the lead-acid battery industry to filter lead dust and lead smoke. The dust content of the gas after filtration is ≤0.07mg / m3, which is far lower than the national emission standard. The filtration resistance is only increased by about 10% on the basis of the previous stage, which better balances the contradiction between filtration accuracy and filtration resistance.

[0003] In summary, the existing cartridge dust collector can only filter out dust that is significantly different in quality from the fluff, has a poor filtering effect, and cannot classify the fluff by volume. To address the above problems, the existing equipment needs to be improved. Summary of the invention

[0014] Preferably, observation windows are arranged on the outer walls of the first cavity, the second cavity and the third cavity, and two groups of manifolds are symmetrically arranged on the upper and lower sides of the observation window outside the third cavity.

[0015] Preferably, a fan connection seat is provided on the wind hood, and the wind hood is communicated with the interior of the housing, and the fan connection seat is connected to an external fan.

[0016] Compared with the prior art, the invention has the following beneficial effects: the cartridge dust collector provided with an amplifier,

[0017] (1) The present invention can effectively solve the problem that the existing filter cartridge dust collector can only filter out dust with a large difference in mass from the fluff, has a poor filtering effect and cannot classify the fluff according to volume through the amplification and separation mechanism. The first suction air amplifier in the amplification and separation mechanism transports the dust, i.e., the fluff, which is blown back from the filter cartridge after preliminary filtration, to the interior of the second cavity through the conveying pipe network. The fluff entering the second cavity floats upward under the upward blowing operation of the second suction air amplifier. The dust in the fluff falls off quickly during the upward blowing process. At the same time, under the same airflow, the height of the fluff with a large mass is lower than that of the fluff with a small mass, so that it can be discharged through the diversion pipes of different heights, thereby realizing the dust removal and automatic classification of the fluff.

[0018] (2) The present invention can effectively solve the problem that the existing filter cartridge dust collector is easily clogged with dust during preliminary filtration, thus requiring frequent disassembly and cleaning, thereby affecting the efficiency of the device, by using a self-cleaning filter mechanism and an external fan. Under the suction action of the external fan, dust, i.e., fluff, enters the interior of the outer shell through the feed port on the inner side of the cover shell with the airflow. The airflow entering the outer shell enters the interior after being filtered by the filter cartridge and moves upward under the action of the suction. During the upward movement, the airflow pushes the sealing seat to move upward along the inner wall of the sleeve, so that its bottom is separated from the sealing gasket, and then the sealing gasket and the sealing seat are separated. The air is discharged into the hood through the gap between them, and then discharged to the designated area under the extraction action of the external fan. When the filter cartridge is blocked, the fan is controlled to stop pumping dust into the device. At this time, the airflow that causes the sealing seat to move upward disappears. Then, under the pumping action of the air pump, the airflow pushes the top of the sealing seat to move down and contact the sealing pad below it to form a seal. The airflow enters the interior of the filter cartridge to be cleaned through the diversion port, the conveying pipeline, the sleeve and the channel on the exhaust pipe in turn, and blows back the fluff adhering to its surface, thereby realizing automatic cleaning, and the operation is convenient, fast and efficient.

[0038] Specifically, in the actual working process, the external fan is installed on the fan connection seat 7, and then the wires in the wiring port 9 are connected to the external power supply and equipment. Under the extraction action of the external fan, the fluff enters the interior of the outer shell 1 through the feed port 5 on the inner side of the cover shell 4 along with the airflow and contacts the filter cartridge 202. After being filtered by the filter cartridge 202, the airflow entering the interior of the filter cartridge 202 moves upward under the extraction action of the external fan. During the upward movement, the airflow pushes the sealing seat 2031 to move upward along the inner wall of the sleeve 2033, so that its bottom is separated from the sealing gasket 205.

Similarly, multiple filter cartridges 202 are back-blown and cleaned in turn.

[0039] After backblowing, the fluff that falls into the inside of the shell 1 slides along its inclined inner bottom surface to the first suction air amplifier 304. The first suction air amplifier 304, in cooperation with the vacuum equipment, allows the fluff to enter and be transported to the inside of the second cavity 302 through the conveying pipe network 305. The fluff that enters the second cavity 302 floats upward under the upward blowing operation of the second suction air amplifier 309. At this time, the dust in the fluff falls quickly during the upward blowing process. At the same time, under the same airflow, the height of the fluff with large mass is lower than that of the fluff with small mass, that is, their floating heights in the third cavity 303 are different. Therefore, under the extraction action of the external equipment, the shunt pipes 307 of different heights can be used to extract the fluff of different masses, thereby realizing the dust removal and automatic grading of the fluff.

[0040] Embodiment 2

[0041] This embodiment is a further description of the above embodiment. It should be understood that this embodiment includes all the aforementioned technical features and is further described in detail.

[0042] The device can also be used for dust collection, that is, under the action of external fan extraction, dust and dirt enter the interior of the outer shell 1 through the feed port 5 on the inner side of the cover shell 4 along with the airflow and come into contact with the filter cartridge 202. After being filtered by the filter cartridge 202, the airflow entering the interior of the filter cartridge 202 moves upward under the action of the external fan extraction. During the upward movement, the airflow pushes the sealing seat 2031 to move upward along the inner wall of the sleeve 2033, so that its bottom is separated from the sealing gasket 205. Then the airflow and dust are discharged to the interior of the wind hood 6 through the gap between the sealing gasket 205 and the sealing seat 2031, and are discharged to the designated area under the action of the external fan extraction. When the filter cartridge 202 is blocked, the fan is controlled to stop pumping dust into the device. At this time, the airflow that causes the sealing seat 2031 to move upward disappears, and the sealing seat 2031 moves downward under gravity and contacts the sealing gasket 205 to form a seal. Then, under the pumping action of the air pump 204, the airflow passes through the diversion port 2035, the conveying pipe 2034, the sleeve 2033 and the channel 2032 on the exhaust pipe in turn to enter the interior of the filter cartridge 202 to be cleaned, and the dust adhering to its surface is blown back to the inside of the outer shell 1.
