Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder production, in particular to a plastic powder particle size anti-blocking detection device. Background Art

[0002] Plastic powder, ultrafine plastic powder, resin powder Plastic is a synthetic high molecular compound, also known as polymer or macromolecule, also commonly known as plastic or resin, which can freely change shape and style. It is a material made by synthesizing or condensing monomer raw materials. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] In the existing technology, after the production of ultrafine plastic powder is completed, the staff needs to perform particle size detection on the plastic powder to ensure the quality of the plastic powder product. However, during the detection process using the particle size detection equipment, the plastic powder often clumps, which affects the detection accuracy. The traditional operation to prevent the plastic powder from clumping is to add a dispersant during the detection to promote the dispersion of the plastic powder, thereby ensuring the detection accuracy. However, this method requires a relatively precise amount of dispersant, and is not effective when detecting plastic powder with larger particle sizes. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a plastic powder particle size anti-blocking detection device.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The discharging opening of the discharging opening is connected with the charging aperture, and the discharging opening is connected with the discharge nozzle, and the discharge nozzle is connected with the detection device; the discharging opening is connected with the delivery inlet, the delivery inlet is arranged on the left side of the upper end surface of the dispersion box, and the delivery outlet is arranged on the right side of the upper end surface of the dispersion box, and the delivery outlet is connected with the left end of the discharge nozzle; the delivery inlet and the delivery outlet are connected by a delivery groove, and the delivery groove is provided on the upper end surface of the dispersion box; the upper end surface of the dispersion box is affixed to the lower end surface of the filter screen, and the filter screen is detachably mounted on the bottom end of the cavity; the cavity is opened at the lower part of the adsorption box, and the upper end surface of the adsorption box is provided with an adsorption channel, the adsorption channel is communicated with a vacuum pump, and the vacuum pump is connected with the discharge nozzle through a connecting pipe; in this way, During plastic powder testing, the plastic powder enters the feed pipe through the feed port. Due to the fitting arrangement of the dispersion box and the adsorption box, the conveying inlet, conveying groove and the upper part of the conveying outlet are sealed by the filter to form a pipeline. The plastic powder in the feed pipe will eventually enter the discharge pipe through the conveying groove. Due to the adsorption action of the vacuum pump, the agglomerated plastic powder in the conveying groove will be adsorbed and stuck on the filter due to its large particle size. At this time, under the impact of the water flow and plastic powder in the feed pipe, the agglomerated plastic powder is continuously impacted and finally dispersed. A part of the plastic powder eventually passes through the conveying outlet and enters the discharge pipe, and another part of the small-particle plastic powder directly passes through the filter into the cavity, and finally enters the discharge pipe through the adsorption channel and the connecting pipe to merge. Therefore, after screening by the filter and continuous impact of the water flow in the conveying groove, the probability of agglomerated plastic powder entering the detection equipment is greatly reduced, and the detection data of the detection equipment is more accurate.

[0007] As a further solution of the present invention: the conveying groove is an S-shaped bending track, which is used to increase the length of the conveying groove, thereby increasing the movement path of the plastic powder and reducing the probability of the plastic powder clumping into the detection equipment.

[0008] As a further solution of the present invention: an ultrasonic oscillation device is provided below the dispersion box, which can further enhance the dispersion effect of the plastic powder flowing in the dispersion box.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] During plastic powder testing, the plastic powder enters the feed pipe through the feed port. Due to the close fitting of the dispersion box and the adsorption box, the delivery inlet, delivery groove, and the upper portion of the delivery outlet are sealed by the filter screen to form a pipeline. The plastic powder in the feed pipe will eventually enter the discharge pipe through the delivery groove. Due to the adsorption effect of the vacuum pump, the plastic powder agglomerated in the delivery groove will be adsorbed and stuck on the filter screen due to its large particle size. At this time, under the impact of the water flow and the plastic powder in the feed pipe, the agglomerated plastic powder is continuously impacted and eventually dispersed. A portion of the plastic powder eventually passes through the delivery outlet and enters the discharge pipe, while another portion of the small-particle plastic powder directly passes through the filter screen and enters the cavity, and eventually enters the discharge pipe through the adsorption channel and the connecting pipe and merges. According to the utility model, the probability of agglomerated plastic powder entering the detection device is greatly reduced through the screening of the filter screen and the continuous impact of the water flow in the delivery groove, and the detection data of the detection device is more accurate.
