Description

Pneumatic dust collector

technical field

The utility model relates to a dust suction device, in particular to a pneumatic dust suction device used in the charged powder industry.

Background technique

In the toner production process, the image quality needs to be continuously tested, and repeated cleaning of the toner cartridge is a necessary work in the toner testing process. Because the toner particles are fine and the specific gravity is small, it is very easy to generate dust during the cleaning process, which will affect human health. Therefore, it must be completed smoothly with the help of a vacuum cleaner. At present, the mainstream vacuum cleaners use the motor to drive the impeller to rotate to generate negative pressure and suck the dust into the dust bin. Since the toner particles are easily rubbed to generate static electricity during the process of being sucked into the dust bin by the vacuum cleaner, the static sparks will cause damage to the continuously running motor, which is prone to fire.

Contents of the invention

The technical problem to be solved by the utility model is to change the vacuum cleaner from the original electric type to the pneumatic type, so that the cleaning site of the powder box is far away from the working site of the motor, avoiding damage to the motor caused by static sparks, and reducing fire hazards.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a pneumatic dust collection device, including a dust collection bin, a casing, a dust suction pipe, and also includes an airflow generator, a filter, an air compressor, and an airflow generator The air outlet of the machine is connected to the high-pressure tank arranged on the casing through the air pipe, the air compressor is connected to the air inlet, and several filters are respectively arranged on the clapboard on the casing.

The beneficial effect of the utility model is that: due to the use of the airflow generator to generate vacuum airflow to absorb dust, the power supply of the air compressor can be separated from the operation site, avoiding damage to the motor caused by static sparks and reducing fire hazards. The bag is changed to a filter, which reduces the secondary pollution caused by cleaning the filter bag dust to the air and reduces the production cost.

Detailed ways

As shown in Figure 1, the pneumatic dust collection device includes a dust collection bin 1, a casing 2, a dust suction pipe 3, and also includes an airflow generator 4, a filter 5 and an air compressor; the airflow generator 4 is welded on the casing The upper end (also can be riveted or screwed), its air outlet is connected with the high-pressure tank 7 arranged on the casing 2 through the air pipe, and the air inlet 8 is connected with the air compressor; the surface of the partition 6 is provided with several The threaded hole that one end of the filter 5 is suitable is screwed into the threaded hole of the dividing plate 6 through one end of several filters 5 with threaded fasteners, and then the filter 5 is fixed with a nut.

The working process is as follows: when the compressed air is supplied to the vacuum generator, the vacuum generator will generate negative pressure to form a vacuum airflow, and the dust will be sucked into the casing under the negative pressure and adsorbed on the filter, and the filter will thoroughly clean the dust and air Separation, when the work is completed, the air source is cut off, the air accumulated in the high-pressure tank is released to form a positive pressure, and the dust adsorbed on the filter is blown into the dust bag.
