Description

Technical Field

[0001] This utility model relates to the field of plastic granule production technology, and in particular to a dust removal device for the production of modified polyphenylene sulfide plastic granules. Background Technology

[0002] Modified polyphenylene sulfide (PPS) plastic granules are granular materials made by adding other polymers, inorganic nanoparticles, or reinforcing fibers to PPS resin through filling, copolymerization, blending, and other methods. Plastic granules have a wide range of applications. The processing of plastic granules includes washing, crushing, dehydration, extrusion, drawing, pelletizing, and packaging. Dust is generated during the washing and crushing processes. The dust diffuses into the air at the work site, which not only affects the on-site working environment, but also directly affects the surrounding natural air environment.

[0003] For example, a dust removal device for plastic granule production disclosed in Chinese patent literature (publication number: CN217616066U) involves pouring the finished plastic granules into the box through the feed inlet. The plastic granules that fall onto the guide plate will roll to the discharge outlet. When the plastic granules roll on the guide plate, the dust adhering to the surface of the plastic granules will fall onto the dust collection hood through the filter holes. By starting the motor, the motor drives the cam to rotate, which in turn pushes the push plate to move. The push plate then drives the moving sleeve to move left and right along the axis of the fixed rod. This allows multiple fixed plates fixedly installed on the outer surface of the moving sleeve to disperse the plastic granules on the guide plate, making the dust adhering to the surface of the plastic granules more thoroughly cleaned.

[0004] However, because the guide plate is tilted, the cam can only drive one set of fixed plates to scatter the plastic particles. As a result, the fixed plates are limited by the rotation cycle of the cam and cannot cover the particles in the entire length of the plate. Therefore, some unscattered plastic particles, carrying dust, will quickly roll through the guide plate to the discharge port, thus reducing the dust removal quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for undispersed plastic particles to remain during dust removal, which reduces the quality of dust removal.

[0008] A connecting pipe is fixedly connected to one side of the dust collection box, and one end of the connecting pipe is fixedly connected to one side of the dust removal box. A collection box and a filter screen are movably inserted into the other side of the dust removal box, and an exhaust fan is fixedly installed at the top of the dust removal box.

[0009] The dust collection box is equipped with a reciprocating dispersing mechanism inside.

[0010] Preferably, the reciprocating dispersing mechanism includes an inclined screen plate, the outer side of which is fixedly sleeved with the inner wall of the dust collector, and an inclined mounting plate is fixedly connected to one side of the inner wall of the dust collector.

[0027] Example

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a dust removal device for the production of modified polyphenylene sulfide plastic granules, including a dust removal box 1. The dust removal box 1 has a sealed door on the front for easy cleaning and maintenance. A dust collection mechanism is installed on one side of the dust removal box 1. A dust collection box 2 is connected to the dust removal box 1 through a connecting pipe 21. The two ends of the connecting pipe 21 are fixedly connected to one side of the dust collection box 2 and one side of the dust removal box 1, respectively, to facilitate airflow. A collection box 22 and a filter screen 23 are movably inserted into the other side of the dust removal box 1 for easy disassembly and cleaning. An exhaust fan 24 is fixedly installed on the upper end of the dust removal box 1 by bolts to provide power for the dust collection process.

[0029] Inside the dust collector 1, the inclined screen plate 3 is fixedly connected to the inner wall of the dust collector 1 by welding or tight fitting, forming the basic structure for particle bearing and preliminary screening. The inclined mounting plate 31 is fixed to the inner wall of one side of the dust collector 1 to provide installation support for other components of the reciprocating dispersing mechanism.

[0030] The upper end of the inclined mounting plate 31 is provided with a sliding groove 32 arranged in a linear array. The slide rod 33 is slidably connected to the inner wall of the sliding groove 32 by a clearance fit to ensure that the slide rod 33 can move smoothly in the groove. The lower end of the slide rod 33 is fixed to the moving plate 34 by welding or bolting. The lower end of the moving plate 34 is also fixedly connected to the striking plate 35 arranged in a linear array by welding or bolting. The lower end of the striking plate 35 is in contact with the upper end of the inclined screen plate 3 so as to strike the particles on the inclined screen plate 3.

[0031] Multiple slide rods 33 are fixedly connected to the upper end of a drive plate 36. A drive groove 37 is opened on the upper end of the drive plate 36. A servo motor 38 is fixedly installed on the upper end of an inclined mounting plate 31 by bolts. Its output shaft is connected to a rotating shaft 39 by a coupling to ensure stable power transmission. One end of the rotating shaft 39 is fixedly connected to a turntable 310 by a key. A drive column 311 is fixedly connected to the upper end of the turntable 310. The drive column 311 is slidably connected to the inner wall of the drive groove 37, thereby converting the circular motion of the turntable 310 into the linear reciprocating motion of the drive plate 36.

[0032] The upper end of the drive plate 36 is fixedly connected to symmetrically distributed guide sliders 312. The guide sliders 312 and guide rods 313 are slidably connected by clearance fit. The two ends of the guide rods 313 are fixedly connected to the front and rear inner walls of the dust collection box 1 by welding or bolts, which plays a role in stabilizing the guide and ensuring the linearity and stability of the movement of the drive plate 36.

[0033] The feed square tube 4 is fixedly connected to the upper end of the dust collector 1 by welding or flange connection, and is used to transport the modified polyphenylene sulfide plastic granules into the dust collector 1. The discharge port 5 is opened on the other side of the dust collector 1, and the granules that have undergone dust removal are discharged from here and enter the subsequent production process.

[0034] The working process of this utility model:

[0035] Step 1: Modified polyphenylene sulfide plastic granules are fed into the dust collection box 1 through the feed square pipe 4 and fall onto the inclined screen plate 3. The servo motor 38 is powered on and runs. The output shaft drives the rotating shaft 39 and the turntable 310 to rotate. The drive column 311 on the turntable 310 slides in the drive slide groove 37, causing the drive plate 36 to reciprocate linearly along the guide rod 313. This, in turn, drives the slide rod 33, the moving plate 34 and the striking plate 35 to reciprocate. The striking plate 35 continuously strikes the granules on the inclined screen plate 3, breaking up the clumps of granules, slowing down the rolling speed of the granules, and extending their contact time with the inclined screen plate 3.

[0036] Step 2: The exhaust fan 24 is started, generating suction. Dust-laden air enters the dust collection box 2 from the dust collection box 1 through the connecting pipe 21. Inside the dust collection box 2, the dust is intercepted by the filter screen 23, and clean air is discharged. The collection box 22 is used to collect the dust intercepted by the filter screen 23. During this process, the dust on the surface of the plastic particles is more easily dislodged due to impact and vibration. Under the action of gravity and the suction of the dust collection mechanism, the dust is separated from the surface of the particles and sucked away by the dust collection mechanism. Finally, the dust-removed particles are discharged from the discharge port 5.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
