Description

A telescopic air box pulse dust removal device

technical field

The utility model belongs to the technical field of metallurgy, and in particular relates to a dust removal device in the production process of a steel coil leveling machine in the production of cold-rolled silicon steel, in particular to an air box pulse dust removal device.

Background technique

In the production process of cold-rolled silicon steel, since the surface of the steel plate is coated with magnesium oxide, a large number of particles still remain on the surface after being treated in a high-temperature annealing furnace. These magnesium oxide particles will produce a large amount of airborne dust pollution when the steel coil stretching and leveling unit is uncoiling. In order to protect the working environment of the operator and reduce the concentration of dust in the air, the air box pulse bag filter is installed in the unit at present, but after a period of use, it is found that due to the unreasonable structure design of the air box pulse bag filter, its dust removal The effect is not good, and there are still some magnesium oxide particles that cannot be removed during the production process, resulting in dust accumulation in the production area, affecting the normal operation of the equipment, reducing productivity, and making the operating environment harsh, causing harm to the operator's body.

Utility model content

The utility model aims at the problem of unreasonable structure design of the air box pulse bag dust collector, and provides an air box pulse dust collector to solve the problem that the existing air box pulse bag dust collector cannot completely remove magnesium oxide particles during the uncoiling process of the leveling unit. question.

The purpose of this utility model is achieved in this way, it includes dust collector air suction pipe, dust suction cover, it is characterized in that the suction air pipe of existing dust collector is divided into upper bushing, lower bushing, and lower bushing connects dust suction Cover, the lower casing moves in the upper casing, the movement of the upper and lower casings is controlled by the telescopic device, the upper part of the telescopic device is fixed on the structural frame of the production line, and the lower part of the telescopic device is connected to the lower casing of the vacuum hood.

The telescoping device of the present utility model can adopt pneumatic mode or electric mode, also can adopt hydraulic pressure type.

Because the utility model divides the dust suction pipe into upper and lower sleeve pipes, the dust suction cover can move up and down, so as to ensure that the dust in the production of the unit can be sucked away by the vacuum cleaner in time, which can not only ensure the smooth operation of the strip steel, but also improve product quality and production efficiency. The main thing is to reduce the dust on the continuous production line, so fundamentally solve the impact on the operation line environment, unit production efficiency and product quality.

Description of drawings

Accompanying drawing is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, concrete structure of the present utility model is described in detail.

As shown in the figure, the utility model includes a dust collector suction pipe and a dust suction cover 3. It is characterized in that the suction pipe of the existing dust collector is divided into an upper casing 1 and a lower casing 2, and the lower casing 2 is connected to the suction pipe. The dust cover 3 and the lower casing 2 are installed in the upper casing 1, and can move up and down in the upper casing 1. The movement of the upper and lower casings is controlled by the telescopic device 4, and the upper part of the telescopic device 4 is fixed on the structural frame 7 of the production line Up, the lower part of the telescopic device 4 is connected to the lower casing 2, and the telescopic device 4 is started to move the lower casing 2 up and down, thereby adjusting the distance between the suction hood 3 of the vacuum cleaner, the strip steel 5 and the rubber roller 6; when the leveling unit flattens the steel strip At this time, start the telescopic device 4 to move the lower casing 2 downward, shorten the distance between the strip steel 5 and the rubber roller 6, so that the generated magnesium oxide dust can be sucked away by the vacuum cleaner in time, and start the telescopic device 4 when the operation line is changed. The device moves the lower casing 2 upwards so that the head and tail of the strip steel 5 can pass through smoothly.

The telescopic device 4 of the present utility model can adopt pneumatic mode or electric mode, also can adopt hydraulic pressure type.
