DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0024] A silent pulse back-flushing direct-exhaust industrial dust collector comprises a mounting chassis 11, a high-negative-pressure vortex fan 12, a dust collection bucket 4 and a dust collecting bucket 8. An organic shell 13 is mounted on the upper end surface of one end of the mounting chassis, a high-negative-pressure vortex fan is mounted in the shell, a dust collection bucket is mounted on the other end of the mounting chassis through a column 5, a dust collecting bucket is docked at the bottom of the dust collection bucket, and a filtering back-flushing mechanism is mounted in the dust collection bucket. The innovation of the invention lies in that the filtering back-flushing mechanism comprises a dust partition 2, a HEPA filter 3 and a back-flushing mechanism 1, an air inlet 6 is provided on the barrel body of the dust collection bucket, a dust partition is mounted on the top of the barrel body of the dust collection bucket, a HEPA filter extending into the barrel body of the dust collection bucket is spaced apart at the bottom of the dust partition, a back-flushing mechanism is mounted on the top of the dust partition, a barrel cover 17 placed on the upper part of the dust collection bucket barrel body is mounted on the upper cover of the back-flushing mechanism, an air outlet is provided on the barrel cover, and the air outlet is connected to the connecting port on the top of the casing through a hose 16. Under the action of negative pressure, the dust in the dust-laden gas sucked into the air inlet of the dust collector is intercepted and falls into the dust collecting barrel. As the dust adheres, the air bag on the dust partition will back-blow the HEPA filter through the solenoid valve, blowing off the dust attached to it and ensuring the filtering performance of the HEPA filter.

[0025] The mounting chassis includes a mounting base and casters installed at the four corners of the bottom of the mounting base. The mounting base is a structure with a mounting notch at one end, and columns are symmetrically installed on the mounting base at both ends of the mounting notch. The dust bin is placed in the mounting notch to facilitate the movement of the dust bin.

[0026] The dust trap is a structure with a mounting hole provided on the plate body, where a HEPA filter is mounted. The backflush mechanism comprises several sets of air bags equipped with solenoid valves, each positioned opposite a HEPA filter. The backflush mechanism, consisting of the air bags and solenoid valves, periodically backflushs the HEPA filter below to clean dust, ensuring its filtration performance and service life.

[0027] In order to further filter out dust in the air, an exhaust muffler box 14 is also included. An exhaust muffler box is placed on the housing. The exhaust muffler box includes a box body, and microporous partitions are arranged at intervals inside the box body. The microporous partitions divide the interior of the box body into a horizontally arranged gas collection chamber 18, a buffer chamber 19, and a dust compartment 20. An exhaust inlet is provided at the top of the gas collection chamber. The exhaust inlet is connected to the hose through a connecting pipe 15. A high-efficiency dust separator 21 is installed in the dust compartment through a dust separator bracket. The top of the dust compartment is a hollow structure. During operation, under the action of negative pressure, the air after the first stage of filtration enters the exhaust muffler box, is filtered by the microporous partition and the dust compartment, and is discharged into the atmosphere after being filtered, thereby reducing air pollution. The exhausted gas is collected by the gas collection chamber and then enters the buffer chamber at the rear through a microporous partition. The microporous partition acts as a porous sound absorber and flows evenly into the buffer chamber in the rear cavity. It is then discharged after being filtered through a high-efficiency dust filter, thus achieving both silencing and further purification of the exhausted gas, thus meeting the safety standard of direct emission.

[0028] In order to facilitate the unloading of dust from the dust collecting bucket, a dust unloading mechanism is also designed. The dust collecting bucket is installed on the column through the dust unloading mechanism. The dust unloading mechanism includes a sliding sleeve 7, a support plate 10 and a handle 9. The sliding sleeve is slidably installed on the column, and a top connection column 22 is installed on the inner side of the two sliding sleeves. The dust collecting bucket is top-connected between the two top connection columns. The handle is a U-shaped structure. The two end portions of the U-shaped structure form connecting ears 23. The upper position of the connecting ears is hinged on the sliding sleeves on both sides. Support plates are provided on both outer sides of the U-shaped structure. The support plate consists of a first vertical section, an inclined section bent outward at the root of the first vertical section, and a second vertical section bent vertically downward at the root of the inclined section. The second vertical section of the support plate is hinged to the column, and the first vertical section of the support plate is hinged to the lower position of the connecting ear. When in use, push the dust bucket into the bottom of the dust removal bucket, use the top connection column on the dust unloading mechanism to clamp the two sides of the dust bucket, then press down the handle, and under the action of the support plate, the sliding sleeve moves up along the column, thereby docking the dust bucket to the bottom of the dust removal bucket; when unloading dust, just lift the handle, which is simple and convenient.

[0029] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
