Description

A dust removal draw frame

technical field

The utility model belongs to and specifically relates to a dust removal type draw frame.

Background technique

In the pure spinning and blending operations of producing wool yarn and wool-cotton fibers, a draw frame is often used for processing, and the function of the draw frame is to improve the internal structure of the sliver, thereby improving the uniformity of its long segment and reducing the weight at the same time Unevenness, make the fibers in the sliver straight and parallel, reduce the hooks, make the fineness meet the requirements, make the raw materials of different types or different qualities mix evenly, and reach the specified mixing ratio.

However, the dust removal function of the existing draw frame is relatively poor, and the dust is only removed by an ordinary exhaust fan, and the dust and sundries are not recycled, and the dust and sundries that have not been recycled are prone to backflow, causing secondary pollution.

Utility model content

The purpose of the utility model is to provide a dust-removing drawing frame capable of reclaiming dust and sundries and avoiding secondary pollution.

In order to solve the problems of the technologies described above, the technical solution of the utility model is:

A dust-removing drawing frame, comprising a cotton conveying board, a strip-shaped through hole is opened on the cotton conveying board, a suction bucket is arranged below the strip-shaped through hole, and a vertical A pair of vertical rods are provided, and a transmission roller is provided on the discharge end side of the cotton conveying board, a conveyor belt is linked above the transmission roller, and a main pipeline is communicated with the suction bucket below, and the suction bucket is connected to the main pipeline. There is a dust removal fan in between, and the diameter of the main pipe gradually increases from one end of the dust removal fan to the other end, and more than one sub-pipe is connected under the main pipe, and each sub-pipe is connected with a dust storage box respectively.

Preferably, grooves are provided inside the pipe wall of the main pipe, and the grooves are spirally distributed on the pipe wall of the main pipe to avoid backflow of dust.

As a preference, the air suction funnel covers the strip-shaped through-hole on the cotton conveying board, and the length of the strip-shaped through-hole is greater than the distance between the two vertical bars, so as to prevent impurities and dust from leaking out of the air suction funnel.

As a preference, more than one pair of the conveying rollers are provided, and the rollers face each other, and the rollers are divided into one upper and one lower opposite rollers.

The technical effect of the utility model is mainly reflected in the following aspects: the negative pressure is generated on the bottom of the cotton conveying board through the dust removal fan, and the dust and debris on the cotton bundle are sucked by the negative pressure, and the sucked dust and debris will pass through the main pipeline through the dust removal fan It is recycled to the dust storage box, and the diameter of the main pipe is gradually enlarged to avoid the backflow of dust and debris, and the effect of removing impurities has been greatly improved.

Detailed ways

In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", etc. The orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the referred device or element must have a specific orientation, be configured in a specific orientation and operation, and therefore cannot be construed as limiting the utility model.

In addition, in this specific embodiment, if the connection or fixing method between the components is not specified in particular, the connection or fixing method can be fixed by bolts or pins commonly used in the prior art, or connected by pin shafts, etc. Therefore, it will not be described in detail in this embodiment.

Example 1

As shown in Fig. 1, a kind of dedusting type drawing frame comprises the cotton conveying board 1 that conveys cotton bundle, is provided with strip-shaped through-hole 2 on described cotton-transferring board 1, and the bottom of described strip-shaped through-hole 2 is provided with A suction bucket 3 that can suck away dust. The suction bucket 3 covers the strip-shaped through hole 2 to avoid dust leakage. A pair of vertical rods for limiting the width of cotton bundles are vertically provided on the output end of the cotton conveying board 1 4. The longitudinal length of the strip-shaped through hole 2 is greater than the distance between the two vertical bars 4, which can completely cover the cotton bundles and prevent dust from leaking. The transmission roller 5 of the bundle, the transmission roller 5 is provided with more than one pair, and mutually opposite rollers, is used for clamping the cotton bundle, and the transmission belt 6 for driving the transmission roller 5 is linked above the transmission roller 5, and the suction bucket 3. There is a main pipeline 7 for preventing backflow of dust at the lower part. Grooves are arranged inside the pipe wall of the main pipeline 7. The grooves are spirally distributed on the pipe wall of the main pipeline 7 to avoid backflow of dust. There is a dust removal fan 8 for generating negative pressure between the suction bucket 3 and the main pipeline 7. The dust removal fan 8 is an axial flow dust removal fan, and the diameter of the main pipeline 7 gradually increases from one end of the dust removal fan 8 to the other end. To avoid dust backflow, more than one sub-pipe 9 is connected below the main pipe 7, and each sub-pipe 9 is respectively connected with a dust storage box 10 for collecting dust.

Principle description:

When working, the conveying belt 6 squeezes the conveying roller 5 and drives the conveying roller 5 to rotate, thereby driving the cotton bundle located between the pair of conveying rollers to be transmitted to the discharge end. During the conveying process, the cotton bundle is limited by a pair of vertical rods 4 At the same time, the cotton bundle on the cotton conveying board 1 removes dust and debris through negative pressure, and the dust and debris are recovered into the dust storage box 10 through the dust removal fan 8. The variable diameter design of the main pipe 7 avoids the backflow of dust and debris .

The technical effect of the utility model is mainly reflected in the following aspects: the negative pressure is generated under the cotton conveying board through the dust removal fan, and the dust and impurities on the cotton bundle are removed through the negative pressure, and the removed dust and impurities will be recycled to the The design of the dust storage box and the gradually increasing diameter of the main pipe avoids the backflow of dust and debris, and the effect of removing impurities has been greatly improved.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model .
