Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, and in particular to a baghouse dust collector. Background Technology

[0002] A baghouse dust collector is an air purification device that filters dust through filter bags and is widely used in industrial dust removal.

[0003] Traditional baghouse dust collectors are mostly rectangular in shape, with funnel-shaped four-corner ash discharge chambers at the bottom to collect dust falling during pulse cleaning. However, in actual operation, a large amount of dust tends to accumulate in the ash discharge chambers. Although the accumulated dust can be discharged through the ash discharge pipe, a large amount of dust often remains on the inner wall of the ash discharge chamber due to electrostatic adsorption, sticky adhesion, or airflow turbulence. This residual dust not only affects the dust removal efficiency of the equipment, but may also cause dust agglomeration and blockage of the ash discharge pipe, increasing equipment maintenance costs. It also has drawbacks such as incomplete ash discharge and cumbersome maintenance. In order to solve the above problems, we have proposed this baghouse dust collector. Utility Model Content

[0004] The main objective of this invention is to provide a bag filter dust collector that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A baghouse dust collector includes a dust collector body and a pulse chamber. The lower end of the dust collector body is provided with a dust discharge shell. The dust discharge shell contains a cleaning mechanism for cleaning accumulated dust. The cleaning mechanism includes multiple mounting pipes disposed on the inner wall of the dust discharge shell. A vertical pipe is connected to all of the mounting pipes. The lower end of the vertical pipe is connected to the mounting shell. A motor is fixedly connected inside the mounting shell. The output shaft of the motor is fixedly connected to a rotating plate. A scraper is provided on the side wall of the rotating plate. A dust discharge pipe is connected to the lower end of the dust discharge shell. A valve is provided on the dust discharge pipe. Multiple support legs are fixedly connected to the side wall of the dust discharge shell. A controller is fixedly connected to the side wall of one of the support legs. A heating mechanism for heating the accumulated dust is provided on the side wall of the dust discharge shell.

[0007] Preferably, the heating mechanism includes a heating sleeve fixedly connected to the side wall of the ash discharge housing, the heating sleeve being provided with a plurality of electric heating rods, and a temperature controller being fixedly connected to the side wall of one of the support legs.

[0008] Preferably, the plurality of electric heating rods are arranged at equal intervals, and a temperature sensor is provided on the side wall of the heating sleeve.

[0009] Preferably, an installation frame is fixedly connected to the upper end of the ash discharge housing, and multiple bolts are provided on multiple side walls of the installation frame.

[0010] Preferably, the rotating plate has multiple screws on its side wall, and the mounting housing has an inclined surface at its upper end.

[0011] Preferably, the pulse chamber is provided with multiple lifting lugs at its upper end, and one of the mounting tubes has an air inlet pipe connected to its side wall.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This device is equipped with a cleaning mechanism. The ash discharge shell adopts a funnel-shaped structure and the inclined inner wall design can use gravity to accelerate the sliding of dust and reduce the accumulation on the wall. The motor in the cleaning mechanism drives the rotating plate and scraper to rotate, which can actively scrape off the dust adhering to the funnel wall. It is especially effective for sticky or fine dust, avoiding the tediousness of manual cleaning and improving the ash discharge efficiency.

[0014] 2. This device is equipped with a heating mechanism. The heating jacket, together with the electric heating rod, can heat the ash accumulated in the ash discharge shell at a constant temperature. The temperature sensor and the temperature controller are linked to control the temperature to prevent the dust from clumping due to moisture. This design can effectively improve the flowability of moist dust and avoid poor ash discharge caused by dust adhesion. It is suitable for handling dust with high moisture content.

[0015] 3. This device is equipped with an installation frame and bolts, a detachable ash discharge shell and a quick-change scraper structure, and a lifting lug design, which reduces equipment maintenance time by 50% and lowers labor costs. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, a bag filter dust collector includes a dust collector body 1 and a pulse chamber 2. The dust collector body 1 and the pulse chamber 2 are existing technologies. The installation and disassembly of the filter cartridges in the dust collector body 1, the internal components of the pulse chamber 2, and the working principle are all existing technologies, so they will not be described in detail. The lower end of the dust collector body 1 is provided with a dust discharge shell 4. The dust discharge shell 4 is provided with a cleaning mechanism for cleaning accumulated dust. The cleaning mechanism includes multiple installation pipes 8 set on the inner wall of the dust discharge shell 4. The multiple installation pipes 8 are connected to a vertical pipe 9. The lower end of the vertical pipe 9 is connected to an installation shell 10.

[0023] A motor 11 is fixedly connected inside the housing 10. The output shaft of the motor 11 is fixedly connected to a rotating plate 12. A scraper 13 is provided on the side wall of the rotating plate 12. A ash discharge pipe 5 is connected to the lower end of the ash discharge housing 4. A valve 6 is provided on the ash discharge pipe 5. Multiple support legs 7 are fixedly connected to the side wall of the ash discharge housing 4. A controller 17 is fixedly connected to the side wall of one of the support legs 7.

[0024] The side wall of the ash discharge housing 4 is provided with a heating mechanism for heating the accumulated ash. The heating mechanism includes a heating sleeve 14 fixedly connected to the side wall of the ash discharge housing 4. The heating sleeve 14 is provided with multiple electric heating rods 16. A temperature controller 18 is fixedly connected to the side wall of one of the support legs 7. The heating sleeve 14 is filled with heating oil.

[0025] In this utility model, multiple electric heating rods 16 are arranged at equal intervals, and a temperature sensor 15 is provided on the side wall of the heating sleeve 14. The probe of the temperature sensor 15 is located inside the heating sleeve 14. The temperature sensor 15 is linked with the temperature controller 18 to control the temperature and realize the constant temperature heating of the ash discharge shell 4.

[0026] In this utility model, an installation frame 3 is fixedly connected to the upper end of the ash discharge housing 4. Multiple bolts are provided on multiple side walls of the installation frame 3, so that the dust collector body 1 and the ash discharge housing 4 can be detachably connected, which facilitates the replacement of the scraper 13.

[0027] In this utility model, the rotating plate 12 has multiple screws on its side wall, making the scraper 13 replaceable. The upper end of the mounting housing 10 has an inclined surface to prevent dust accumulation.

[0028] In this utility model, the upper end of the pulse chamber 2 is provided with multiple lifting lugs 20. The dust collector body 1 can be easily removed for cleaning and maintenance of the ash discharge shell 4 by means of the lifting lugs 20, ropes and external lifting tools. One of the mounting pipes 8 has an air inlet pipe 19 connected to its side wall. Both the mounting pipe 8 and the vertical pipe 9 are hollow. The lower end of the mounting shell 10 is provided with an air outlet net (not shown in the figure). Air can be injected into the mounting shell 10 through the air inlet pipe 19 to achieve ventilation inside the mounting shell 10.

[0029] In the initial state, the air inlet pipe 19 is connected to a fan, the dust collector body 1 is connected to the dust collection station through a pipe, and the pulse chamber 2 is connected to an external fan.

[0030] During use, when the pulse chamber 2 is performing pulse cleaning, the dust falls from the filter bag into the funnel-shaped ash discharge housing 4. The inclined inner wall uses gravity to accelerate the dust to slide down the ash discharge pipe 5. At the same time, the motor 11 drives the scraper 13 to rotate slowly, continuously scraping off the dust adhering to the wall surface, avoiding dust retention due to static electricity or stickiness, and ensuring efficient discharge of accumulated ash.

[0031] Heating and drying dust: The electric heating rod 16 heats the heating oil in the heating jacket 14, and the ash discharge shell 4 is kept at the set temperature through heat conduction (monitored in real time by the temperature sensor 15 and the temperature controller 18). The heated dust has increased fluidity due to the reduced humidity. Especially for damp or easily clumping dust, it can prevent it from sticking and accumulating on the wall. With the rotation of the scraper 13, the dust can be completely discharged.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
