Description

Technical Field

[0001] This utility model relates to the field of sintered plastic plate dust collectors, specifically a novel uniform air distribution mechanism for sintered plastic plate dust collectors. Background Technology

[0002] The sintered plastic plate dust collector consists of a housing, frame, dust removal device, ash discharge device, and electrical control device. Its structural feature is that the filter element is a sintered plastic plate, and all filters are cleaned using a pulse-jet cleaning device. The dust removal device comprises an ash storage tank, a duct, a distribution manifold, a controller, pulse valves, and blowpipes. The working principle of the sintered plastic plate dust collector is basically the same as that of a conventional baghouse dust collector. The dust-laden airflow enters the central housing (dust chamber) through the duct. When the dust-laden gas passes through the outer surface of the sintered plastic plate, the dust is trapped on the PTFE coating on the outer surface of the plate. The clean airflow passes through the outer surface of the sintered plastic plate, enters the clean air chamber through the inner cavity of the plate, and is discharged through the exhaust duct. As dust accumulates on the surface of the sintered plastic plate, the electronic pulse controller or PLC program can automatically select the sintered plastic plate that needs to be cleaned according to the constant resistance or time control mode, trigger the opening of the blow valve, and spray compressed air into the inner cavity of the sintered plastic plate to blow away the dust accumulated on the outer surface of the sintered plastic plate. The dust falls into the hopper under the action of airflow and gravity.

[0003] For example, utility model patent CN218076879U discloses a novel sintered plastic plate dust collector capable of uniform air distribution, including a dust collection box containing sintered plastic plates. A dust hopper is located at the bottom of the dust collection box, and two uniform air distribution components are symmetrically arranged within the dust hopper. Each uniform air distribution component includes a semi-circular duct. The middle of the semi-circular duct is connected to a dust inlet duct, and the outer end of the dust inlet duct extends outward through a pre-reserved opening on the side wall of the dust hopper. Both ends of the semi-circular duct are closed structures, and an air outlet is provided at the bottom of the semi-circular duct along its arc. The width of the air outlet is smaller than the diameter of the semi-circular duct. This utility model reasonably adjusts the airflow distribution, improves the overall dust removal efficiency, and extends the service life of the sintered plate. However, there is a problem that the smoke and gas blown out through the semi-arc duct cannot completely and evenly contact the lower surface of the sintered plate. This causes the smoke and gas to remain in contact with a fixed position on the lower surface of the sintered plate for a long time, ultimately reducing the service life of the sintered plate itself. To address this, we propose a new uniform air distribution mechanism for a sintered plate dust collector. Utility Model Content

[0004] The purpose of this invention is to provide a novel uniform air distribution mechanism for a sintered plastic plate dust collector, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel uniform air distribution mechanism for a sintered plastic plate dust collector, comprising a dust collection box, a jetting assembly at the top of the dust collection box, an annular groove on the inner wall of the dust collection box, and an air intake uniform contact assembly on the inner side of the dust collection box. The air intake uniform contact assembly includes an L-shaped air intake pipe that is fixedly connected to the dust collection box. A fixed frame is fixedly connected to the inner wall of the vertical end of the L-shaped air intake pipe. A follower shaft is rotatably connected to the inner end of the fixed frame via a bearing. Multiple circumferentially distributed rotating fan blades are fixedly connected to the lower end of the follower shaft. A gear is fixedly connected to the upper end of the follower shaft through the L-shaped air intake pipe. An internal gear ring is meshed with the outer end of the gear. A rotating ring is fixedly connected to the outer end of the internal gear ring. An annular groove is slidably connected to the inner wall of the rotating ring. A sintered plastic plate body is detachably connected to the upper end of the internal gear ring. An air passage pipe is fixedly connected to the right side of the vertical end of the L-shaped air intake pipe. Multiple evenly distributed air outlets are opened on the upper side of the outer end of the air passage pipe.

[0006] Preferably, the blowing assembly includes a box cover that is detachably connected to a dust collection box. An air outlet pipe is fixedly connected to the upper middle part of the box cover. Two symmetrically arranged contact frames are fixedly connected to the lower end of the dust collection box. An air duct is fixedly connected to the lower end of the contact frames. A plurality of evenly distributed blowing pipes are fixedly connected to the lower end of the air duct. An air intake pipe is fixedly connected to the upper right side of the air duct. An axial flow fan is fixedly connected to the tail end of the air intake pipe, and the lower end of the axial flow fan is fixedly connected to the box cover.

[0007] Preferably, the lower end of the dust collection box is fixedly connected to a plurality of circumferentially distributed brackets, and each bracket is fixedly connected to an anti-slip pad at its lower end.

[0011] Preferably, the rotating fan blades are located at the lower part of the air duct.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Equipped with a dust collection box, support frame, anti-slip mat, pulse jet assembly, dust collection bin, annular groove, and uniform air inlet contact assembly, this device allows for the extraction of dust-laden gas by an external fan. The dust-laden gas enters the dust collection box through an L-shaped inlet pipe and an air duct. This gas drives the rotating fan blades, which in turn drive the follower shaft. The follower shaft then drives the gears, which in turn drive the internal gear ring. The internal gear ring rotates within the annular groove, causing the sintered plastic plate to rotate. During this process, the dust-laden gas is blown out from the outlet, ensuring uniform contact between the gas and the sintered plastic plate. This invention achieves uniform rotation of the sintered plastic plate through the dust-laden gas entering the dust collection box, improving the performance of the sintered plastic plate and reducing damage to it.

[0014] 2. The dust collection box and the blowing assembly allow the gas passing through the sintered plastic plate to be blown out through the air outlet pipe. When it is necessary to blow the sintered plastic plate, the axial flow fan can be powered on. The axial flow fan draws in outside air into the dust collection box. The outside air then passes through the air duct and the blowing pipe to blow the sintered plastic plate, thus cleaning the dust from the sintered plastic plate. Attached Figure Description

[0022] In this embodiment, the blowing assembly 4 includes a box cover 41 and the box cover 41 is detachably connected to the dust collection box 1. An air outlet pipe 42 is fixedly connected to the middle of the upper end of the box cover 41.

An air passage plate 44 is fixedly connected to the lower end of the contact frame 43. A plurality of evenly distributed blowing pipes 45 are fixedly connected to the lower end of the air passage plate 44.

[0023] Specifically, the gas passing through the sintered plate body 710 can be blown out from the air outlet pipe 42 through the dust collection box 1 and the blowing assembly 4. When it is necessary to blow the sintered plate body 710, the axial flow fan 47 can be powered. The axial flow fan 47 draws outside air into the dust collection box 1. The outside air passes through the air passage plate 44 and the blowing pipe 45 to blow the sintered plate body 710, thus realizing the cleaning of dust from the sintered plate body 710.

This dust-laden gas drives the rotating fan blades 76, which in turn rotate the follower shaft 74. The follower shaft 74 then drives the gear 73, which in turn rotates the internal gear ring 72. The internal gear ring 72 rotates within the annular groove 6, causing the sintered plate body 710 to rotate. During this process, the dust-laden gas is blown out from the outlet 79, making uniform contact with the sintered plate body 710. In this process, the dust-laden gas passes through the sintered plate body 710... Gas is blown out from the exhaust pipe 42. When it is necessary to perform a blowing action on the sintered plate body 710, the axial flow fan 47 can be powered. The axial flow fan 47 draws outside air into the dust collection box 1.
