Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a plastic particle screening machine. Background Art

[0002] The screening machine is a vibrating screening machine that uses the relative movement between the bulk material and the screen surface to allow some particles to pass through the screen holes, and separates materials such as sand, gravel, and crushed stone into different grades according to particle size. The screening process of the screening machine is generally continuous. After the screened raw materials are fed to the screening machine, the materials smaller than the screen hole size pass through the screen hole, which is called the undersize product, and the materials larger than the screen hole size are continuously discharged from the screen surface, which is called the oversize product.

[0003] A plastic pellet screening machine (CN206718235U) currently available includes a frame, a screening hopper, and a vibrating motor that drives the hopper. The hopper is equipped with a screen and a feed hopper at one end. The feed hopper is equipped with a cooling device for cooling the plastic pellets. A discharge port and a coarse material recovery port are located at the end of the hopper away from the feed hopper. The coarse material recovery port is equipped with a disintegrating device for breaking up agglomerated pellets. A conveying device is located between the outlet of the disintegrating device and the hopper to transport the disintegrated plastic pellets. The cooling device cools the plastic pellets, while the disintegrating device breaks up agglomerated pellets, improving screening efficiency and reducing waste. The provision of spiral guide plates and ventilation holes increases the cooling time of the plastic pellets by the fan, enhancing the cooling effect and preventing the pellets from clumping.

[0004] However, the above utility model filters particles by means of vibration and tilting and rolling during use, which causes large particles to block the gaps in the screen and small particles do not enter the lower layer and are discharged together with the large particles, thus affecting the screening quality.

The above-mentioned solution solves the problem that the existing device filters particles by vibration and tilting and rolling during use, resulting in large particles blocking the gaps in the screen and small particles not entering the lower layer and being discharged together with the large particles, thereby affecting the screening quality.

[0021] In this embodiment, the spring column 107 is connected to the support frame 101 and is located on the top of the support frame 101. The first filter tank 104 and the second filter tank 105 are respectively connected to the spring column 107 and are located on the top of the spring column 107. The feed trough 109 is provided at the discharge port of the first filter tank 104. The lifting member 108 is connected to the feed trough 109 and is located on one side of the feed trough 109. Two groups of the collecting members 106 are provided on the inner side of the support frame 101. The vibration motor 103 is connected to the support frame 101 and is located on one side of the support frame 101. The first filter tank 104 and the second filter tank 105 filter particles of the same size. The second filter tank 105 is used for secondary filtering. Filter, pour the particles that need to be filtered and screened from the higher end of the first filter tank 104, perform a filtering and screening through the first filter tank 104, the vibration motor 103 accelerates the filtering efficiency, and the particles that fail to pass the filtration enter the feed trough 109 from the discharge port of the first filter tank 104, and then enter the lifting component 108, and are lifted by the lifting component 108 and discharged into the second filter tank 105 for secondary filtering and screening. The two groups of collecting components 106 are respectively used to collect particles that pass the filtering and screening and particles that fail the filtering and screening, so as to solve the problem that the existing device filters particles by vibration and tilting and rolling during use, resulting in large particles blocking the gaps in the screen, and small particles do not enter the lower layer and are discharged together with the large particles, affecting the screening quality.

[0022] In which, the collecting component 106 includes a collecting box 110 and a roller 111. The collecting box 110 is arranged on the inner side of the supporting frame 101. The roller 111 is rotatably connected to the collecting box 110 and is located at the bottom of the collecting box 110. The collecting box 110 is used to collect filtered and screened particles. Two collecting boxes 110 are provided, one for collecting small particles passing through the first filter tank 104 and the second filter tank 105, and the other for collecting large particles that have not passed through the second filter tank 105.

[0023] Secondly, the lifting component 108 includes a first motor 112, a circular tube 113, an auger 114 and a discharge pipe 115.

The discharge pipe 115 is connected to the circular tube 113 and is located at the top of the second filter tank 105. The first motor 112 drives the auger 114 to rotate. During the rotation, the auger 114 lifts the particles discharged into the circular tube 113, and then the particles are discharged into the second filter tank 105 by the discharge pipe 115 for secondary filtration.

[0024] Again, the filter assembly 102 also includes a feed hopper 116 and a scattering component 117. The feed hopper 116 is fixedly connected to the support frame 101 and is located at the top of the first filter tank 104. The scattering component 117 is connected to the feed hopper 116 and is located on the inner side of the feed hopper 116. The particles to be screened are poured into the feed hopper 116, and the poured particles are scattered by the scattering component 117 in the feed hopper 116 to avoid adhesion between the particles.

[0025] Finally, the breaking up component 117 includes a second motor 118, a rotating shaft 119 and a support rod 120. The second motor 118 is fixedly connected to the feed hopper 116 and is located on one side of the feed hopper 116.

[0026] When using a plastic particle screening machine of the present invention, the first filter tank 104 and the second filter tank 105 filter particles of the same size, and the second filter tank 105 is used for secondary filtration. The particles to be filtered and screened are poured from the higher end of the first filter tank 104, and filtered and screened once through the first filter tank 104. The vibration motor 103 accelerates the filtration efficiency, and the particles that fail to pass the filtration enter the feed trough 109 from the discharge port of the first filter tank 104, and then enter the lifting member 108. After being lifted by the lifting member 108, they are discharged into the second filter tank 105 for secondary filtration and screening. The two groups of collecting members 106 are respectively used to collect particles that pass the filtration and screening and particles that fail the filtration and screening, which solves the problem that the existing device filters particles by vibration and tilting and rolling during use, resulting in large particles blocking the gaps in the screen, and small particles not entering the lower layer are discharged together with the large particles, affecting the screening quality.
