Description

A dust explosion-proof bag filter

technical field

The utility model relates to the technical field of dust collectors, in particular to a dust explosion-proof bag dust collector.

Background technique

The bag dust removal method is a dry dust removal device, which is suitable for capturing fine, dry non-fibrous dust. When the dust-containing gas enters the bag filter, the dust with large particles and heavy specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified. , The dust on the filter bag is removed by the method of spraying pulse air flow, so as to achieve the purpose of cleaning the dust, and the dust removed is discharged by the ash discharge device. When the exhaust gas contains oil mist in addition to dust, the oil mist will adhere to the surface of the filter material. When a large amount of oil mist adheres to the surface of the filter material, pulse backflushing cannot achieve dust removal, resulting in blockage of the filter material and equipment. Unusable, the filter material is changed frequently, and the operating cost is high.

Preferably, the sweeping mechanism includes two reciprocating screws and a scraping frame, a placement slot is symmetrically formed on the inner wall of the air inlet pipe, one end of the two reciprocating screws is rotatably connected to the bottom of the placement slot, and the two The other end of the reciprocating screw extends out of the placing slot and is connected with a second bevel gear;

Two first bevel gears are installed on the rotating shaft, and the two second bevel gears are respectively meshed with their corresponding two first bevel gears;

The scraper frame is located inside the air inlet pipe, and two sides of the scraper frame are connected with sleeves, and the two sleeves are respectively connected with the corresponding two reciprocating screws.

Preferably, there are a plurality of the blocking frames and are distributed on the rotating shaft in a circumferential manner.

Preferably, water spray pipes are installed on both of the support plates.

Preferably, a brush is installed around the hanging frame.

The utility model provides a dust explosion-proof bag filter, the beneficial effect is: when the dust explosion-proof bag filter is used, the dust containing oil mist enters the device through the air intake pipe, because the dust enters the device with a certain initial speed. , so the dust with the dust will enter the oil filter screen to filter the oil mist, and the baffle frame will also rotate under the drive of the dust with a certain speed, quickly capture the dust inside the device, and speed up the oil mist. The high filtration speed greatly reduces the concentration of oil mist in the device, avoiding the problem of frequent replacement of filter materials, thereby increasing work efficiency.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Example 1

Referring to Figure 1-3, a dust explosion-proof bag filter includes a box 1, an air intake pipe 2, and a dust-proof cloth bag 4. An air intake pipe 2 is installed at the bottom of one side of the box body 1, and a collection device is opened directly below the bottom of the box body 1. Port 5, a dustproof cloth bag 4 is arranged inside the box body 1, an air outlet pipe 3 is installed on one side of the box body 1, a scraping mechanism is arranged inside the air inlet pipe 2, and two support plates 6 are fixed on the inner wall of the box body 1, two A water spray pipe 16 is installed on the support plate 6 to increase the weight of the dust in the device, thereby increasing its falling speed. A rotating shaft 7 is arranged between the two support plates 6, and the two ends of the rotating shaft 7 extend into the two support plates 6 respectively. , a baffle frame 8 is installed on the surface of the rotating shaft 7, the baffle frame 8 is facing the intake pipe 2, an oil filter screen 9 is installed in the baffle frame 8, the scraping mechanism includes two reciprocating screws 11 and a scraping frame 14, the inner wall of the intake pipe 2 A placement slot 12 is symmetrically opened, one end of the two reciprocating screws 11 is rotatably connected to the bottom of the placement slot 12, and the other end of the two reciprocating screws 11 extends out of the placement slot 12 and is connected with a second bevel gear 13;

Two first bevel gears 10 are mounted on the rotating shaft 7, and two second bevel gears 13 are respectively meshed with their corresponding two first bevel gears 10;

The scraping frame 14 is located inside the intake pipe 2, and the two sides of the scraping frame 14 are connected with sleeves 15, and the brushes 17 are installed around the scraping frame 14 to increase the scraping efficiency of the grease attached to the intake pipe 2. The two sleeves The barrels 15 are respectively connected with the corresponding two reciprocating screws 11 by screwing.

Working principle: When in use, when the intake pipe 2 starts to take in air, the dust containing oil mist enters the device through the intake pipe 2. Since the dust enters the device with a certain initial speed, the dust with the oil will enter the filter. The oil net 9 filters out the oil mist in it, and at the same time, the blocking frame 8 will also rotate under the driving of the dust with a certain initial speed, quickly capture the dust inside the device, and speed up the filtering speed of the oil mist. At the same time, the two first bevel gears 10 will be driven to rotate, and the rotation of the two first bevel gears 10 will drive the two second bevel gears 13 meshing with them to rotate. At this time, the reciprocating screw 11 will also rotate accordingly. Both ends are connected to the sleeves 15, and the two sleeves 15 are respectively connected with the reciprocating screw 11, so the scraper frame 14 will reciprocate along the direction of the reciprocating screw 11 to prevent the oil mist sticking inside the intake pipe 2 Scrape it to prevent clogging of the intake pipe.
