Description

A sander dust removal device

technical field

The utility model relates to a dust removal device, in particular to a sander dust removal device.

Background technique

Sanding machines will produce a large amount of particles and dust in daily production and use. If dust removal equipment is not used, a large amount of dust will float in the air, which will not only pollute the environment, but also endanger human health. Most of the existing sanding machine dust removal devices use bag type dust collectors. Since a large amount of particulate matter is generated when the sander is working, the thickness of the dust layer in the bag type dust collector increases rapidly. With the increase of the thickness of the dust layer, the filter resistance As it becomes larger, the dust removal efficiency of the bag filter will drop significantly. Therefore, dust removal operations must be performed frequently, and many people cannot accurately judge when the dust should be removed, resulting in cumbersome operations, low dust removal efficiency, and affecting work. issues such as efficiency.

Utility model content

The dust-laden air flow is pre-dedusted by the sedimentation dedusting device and then enters the bag-type dedusting device to complete the secondary purification. The bag-type dedusting device has the function of dust removal reminder.

The technical solution adopted by the utility model to solve the technical problem is: a sander dust removal device includes a sedimentation dust removal device and a bag type dust removal device. There is an ash hopper with an observation window, the bottom of the ash hopper is equipped with a second cleaning valve, the upper part of the bag type dust collector is a clean air chamber, the middle position is equipped with a filter bag, and the bottom is equipped with a first cleaning valve. The blowing pipe is installed near the filter bag in the air chamber, the pulse valve is installed on the right side of the blowing pipe, the exhaust pipe is installed on the right side of the bag dust collector, the gas flow meter and alarm are installed on the exhaust pipe, the sedimentation dust removal device and The bag-type dust collector is connected through a gas pipeline, and a fan is installed on the gas pipeline.

In the above dust removal device for a sander, the air inlet of the fan is connected to the air outlet of the sedimentation dust removal device through an air pipeline; the air outlet of the fan is connected to the air inlet of the bag dust removal device through an air pipeline ; The interior of the settling dust removal device is a hollow structure, and the bottom communicates with the ash hopper; the top of the filter bag communicates with the clean air chamber.

In the above-mentioned dust removal device for a sander, the observation window is located at the middle upper position of the ash hopper, and glass sheets are inlaid on the observation window.

In the aforementioned dust removal device for a sander, the first dust removal valve and the second dust removal valve are rotary valves.

Compared with the prior art, the utility model has the following advantages and outstanding effects:

The beneficial effect of the utility model is that the utility model adopts two-stage dust removal, and the pre-dust removal function of the sedimentation dust removal device can remove a large amount of dust particles with large particle diameters, effectively reducing the dust removal pressure of the bag type dust removal device, and the processing capacity of the dust removal device Greatly increased, the dust cleaning cycle of the dust removal device is significantly increased, which effectively reduces the tedious operation of frequent dust removal of the bag type dust removal device. When the time comes, the dust removal operation is carried out in time to ensure the working efficiency of the device.

Detailed ways

A sander dust removal device includes a sedimentation dust removal device 1 and a bag type dust removal device 10. The left side of the sedimentation dust removal device 1 has a dust-containing airflow inlet 17, a partition 2 is installed inside, and an ash bucket 15 is arranged at the bottom. There is an observation window 16, a second dust removal valve 14 is installed at the bottom of the ash hopper 15, the upper part of the bag type dust removal device 10 is a clean air chamber 4, a filter bag 12 is installed in the middle, and a first dust removal valve 11 is installed at the bottom. In the air chamber 4, near the filter bag 12, there is a blowing pipe 5, a pulse valve 9 is installed on the right side of the blowing pipe 5, an exhaust pipe 6 is installed on the right side of the bag type dust removal device, and a gas flow meter is installed on the exhaust pipe 6 8 and alarm 7, the sedimentation dust removal device 1 and the bag dust removal device 10 are connected through the air pipeline 3, and the air pipeline 3 is equipped with a fan 13, and the dust-laden air flow enters the sedimentation dust removal device 1 through the dust-laden air inlet 17, and the space becomes larger The velocity of the airflow slows down, and the impact kinetic energy of the particle dust and the partition 2 decreases, and gradually settles down under the action of gravity, and is collected in the ash hopper 15, and the inside of the ash hopper 15 can be observed in real time through the observation window 16 on the ash hopper 15 When the dust accumulation is large, the second dust removal valve 14 can be opened to empty the dust, and the gas after the initial settlement enters the gas pipeline 3, and enters the bag type dust collector 10 after being pressurized by the fan 13. Dust is adsorbed and deposited when passing through the filter bag 12, and the airflow after secondary purification is discharged through the exhaust pipe 6. With the operation of the device, the dust layer on the surface of the filter bag 12 accumulates thicker and thicker, and the filtration resistance of the filter bag 12 It also increases accordingly, and the gas flow rate gradually decreases. When the gas flow meter 8 detects that the gas flow rate drops to a certain value, the alarm 7 will alarm and prompt the operator to clean the filter bag. Ash valve 11, then open the pulse valve 9, the pulse air flow passes through the blowing pipe 5 to reversely blow the filter bag 12, the dust layer breaks away from the filter bag 12 and falls to the bottom of the bag filter 10 when blowing, and then passes through the first cleaning Ash valve 11 discharges.
