technical field

The utility model relates to the technical field of engineering plastic processing, in particular to a PBT plastic dust removal device.

Background technique

During the production process of plastic particles, PBT plastic particles are easy to wear and tear, and friction will occur between PBT plastic particles and PBT plastic particles, PBT plastic particles and the pipe wall, resulting in the appearance of fine dust, and plastic particles will be in the process of constant friction. Static electricity is generated, and static electricity will make plastic particles and dust adhere together; at the same time, plastic particles are used as commodities, and the dust will increase the impurity content of plastic particles and reduce the commodity value of plastic particles.

In the prior art, the utility model patent with the application number "201420303700.3" discloses a vibrating sieve plate for plastic particles. The vibrating sieve plate is used as the final recovery process of plastic particles, so it is necessary to remove dust in this process, but there is still Static electricity between plastic particles and dust.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a PBT plastic dust removal device for removing powder in plastic particles.

In order to achieve the above object, the utility model provides the following technical solutions: a PBT plastic dust removal device, including a frame, the frame is fixedly connected with a vibrating sieve plate, and the vibrating sieve plate is provided with a discharge port for plastic particles , the frame includes a column, and a support bar is provided between adjacent columns, and a fan for dust removal is provided on the support bar, and the fan is provided with an adjustment fan to adjust the position of the support bar. device, a negative ion generator is arranged behind the fan.

Preferably, the adjustment device includes an L-shaped frame, which is fixedly connected to the fan, and an adjustment hole is arranged on the L-shaped frame, and a fixing bolt is arranged in the adjustment hole, and the L-shaped frame passes through The fixing bolt is fixed with the cooperation of the adjusting hole.

Preferably, the cross-sectional shape of the adjusting groove is T-shaped, and the cross-sectional shape of the adjusting block is T-shaped.

By adopting the above-mentioned technical scheme, the fan provides lateral airflow to the discharge port. Since the suspension speeds of plastic particles and dust in the air are different, that is, the plastic can directly fall downward due to gravity, while the dust is received by the lateral flow provided by the fan. The air flow is blown away from the vibrating sieve plate to complete the separation of dust and plastic particles. In order to enhance the separation effect, the negative ion generator provides air with negative ions, and the fan blows the air with negative ions onto the plastic particles, thereby reducing the amount of plastic particles. Static electricity between the dust and the dust, and then the dust is separated from the plastic particles, thereby achieving the effect of removing dust from the plastic particles, reducing the impurities in the PBT plastic particles, and improving the quality of the PBT plastic particles.

Detailed ways

The embodiment of the utility model will be further described with reference to Fig. 1 to Fig. 4 .

As shown in Figure 1, a kind of PBT plastic dedusting device comprises a frame, and the frame is fixedly connected with a vibrating sieve plate 3, and the vibrating sieve plate 3 is provided with a discharge port 21 for plastic particles, and the discharge port 21 is used for transporting plastic particles Pipeline or the discharge port 21 of the reaction kettle 2 for preparing plastic particles, the frame includes a column 01, a support cross bar 02 is arranged between the adjacent columns 01, and a fan 4 for dust removal is arranged on the support cross bar 02, and the fan 4 is arranged on the support cross bar 02. 4 is provided with an adjustment device 1 for adjusting the position of the fan 4 on the support bar 02, and an anion generator 5 is arranged behind the fan 4, and the anion generator 5 is adopted, and the anion generator 5 adopts the model JP-A2241 produced by Jingpin Company Negative ion generator 5, negative ion generator 5 belongs to the prior art, does not go into details here, produces a large amount of air with negative ions behind fan 4 by negative ion generator 5, and fan 4 blows the air with negative ions to plastic particles First, the positively charged dust on the plastic particles is neutralized by negative ions, thereby eliminating the static electricity between the plastic particles and the dust, making the dust fall from the plastic particles, and enhancing the dust removal effect of the fan 4 .

As shown in Figures 1 and 2, the adjustment device 1 includes an L-shaped frame 11, which is fixedly connected to the fan 4, that is, one end of the L-shaped frame 11 is connected to the fan 4, and an adjustment hole is arranged on the L-shaped frame 11. 111, the adjustment hole 111 is an oblong hole, the adjustment hole 111 is provided with a fixing bolt 112, the L-shaped frame 11 is fixed by the cooperation of the fixing bolt 112 and the adjustment hole 111, at this time, the fan 4 can be connected by the adjustment hole 111 and the fixing bolt 112 The position is the axis to rotate, while the L-shaped frame 11 can adjust the position between the fan 4 and the discharge port 21 through the adjustment hole 111, and the position between the fan 4 and the discharge port 21 can be adjusted through the adjustment hole 111 L-shaped bracket 0 position; because the discharge port 21 of the reactor 2 cannot be known when the vibrating sieve plate 3 is installed, the position of the discharge port 21 of the reactor 2 can only be determined after the installation of the reactor 2 is completed, and then the adjustment hole 111 is the fan 4 Two degrees of freedom of rotation and movement are provided on the support cross bar 02, which is convenient for fine-tuning the air outlet position of the fan 4, and then achieves the best dust removal effect.
