Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic granulation equipment and relates to a discharging device for bagging plastic particles. Background Art
[0002] Plastic granules are segmented granules formed after being extruded by an extruder and then water-cooled and cut. When the processed plastic granules are packaged, in order to improve the quality of the product, the powder in the plastic granules needs to be filtered out. The current practice is to use a filter screen or filter mesh to sieve the material before bagging. The defects of this method are: on the one hand, sieving cannot fully filter out the powder, because in addition to the powder separated from the large particles, some powder adheres to the surface of the large particles. Therefore, the powder removal effect of sieving is poor. On the other hand, dust is generated during the sieving process, affecting the environment in the workshop. Utility Model Content
[0003] The purpose of the utility model is to provide a discharging device for bagging plastic particles in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the utility model is how to complete the dust separation when bagging and discharging plastic particles.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a discharging device for bagging plastic particles, characterized in that it includes a feed hopper, a discharging pipe and a dust removal sleeve located outside the discharging pipe, the dust removal sleeve is provided with a partition cylinder, a gap is provided between the lower end of the partition cylinder and the bottom of the dust removal sleeve, the upper end of the dust removal sleeve is provided with an air suction pipe, the air suction pipe is connected to a negative pressure air source, the air inlet of the air suction pipe is located outside the partition cylinder, and a plurality of filters are provided on the wall of the discharging pipe.
[0005] Furthermore, an ash discharge port is provided at the lower end of the partition cylinder, and a plug is connected to the ash discharge port.
[0006] Furthermore, a plurality of guide plates are arranged in the discharge pipe, and one end of the guide plate away from the wall of the discharge pipe is inclined downward.
[0007] The suction pipe is connected to the negative pressure air source. Under the action of negative pressure, the plastic particles entering the discharge pipe from the hopper are affected by the negative pressure airflow. The dust passes through the filter and hits the inner wall of the partition tube and sinks to the bottom. When there is a lot of dust accumulated on the bottom, the ash discharge port can be opened for ash discharge. This method can complete the separation of material dust when bagging and unloading, without the need to set up a separate dust filtration process. In addition, due to the presence of the guide plate, the retention time of the material in the discharge tube is extended, the path is also extended, and the collision of the material to separate the dust and large particles is more effective.
[0008] In summary, this scheme can not only avoid dust and optimize the workshop environment, but also improve the dust separation efficiency and dust separation rate, and improve the product quality of plastic particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0012] like Figure 1 The discharging device for bagging plastic particles shown in the figure includes a feed hopper 1, a discharging pipe 2 and a dust removal sleeve 3 located outside the discharging pipe 2, a partition cylinder 4 is provided inside the dust removal sleeve 3, a gap is provided between the lower end of the partition cylinder 4 and the bottom of the dust removal sleeve 3, an air suction pipe 5 is provided at the upper end of the dust removal sleeve 3, the air suction pipe 5 is connected to a negative pressure air source, an air inlet of the air suction pipe 5 is located outside the partition cylinder 4, and a plurality of filters 6 are provided on the wall of the discharging pipe 2.
[0013] An ash discharge port 7 is provided at the lower end of the partition cylinder 4, and a plug is connected to the ash discharge port 7.
[0014] A plurality of guide plates are arranged in the discharge pipe 2, and one end of the guide plates away from the pipe wall of the discharge pipe 2 is inclined downward.
[0015] The suction pipe 5 is connected to a negative pressure air source. Under the action of negative pressure, the plastic particles entering the discharge pipe 2 from the feed hopper 1 are affected by the negative pressure airflow. The dust passes through the filter screen 6 and hits the inner wall of the partition tube 4 and sinks to the bottom. When there is a lot of dust accumulated on the bottom, the ash discharge port 7 can be opened for ash discharge. This method can complete the separation of material dust during bagging and unloading, without the need to set up a separate dust filtering process. In addition, due to the presence of the guide plate, the retention time of the material in the discharge barrel is extended, the path is also extended, and the collision of the material to separate the dust and large particles is more effective.
[0016] In summary, this solution can not only avoid dust and optimize the workshop environment, but also improve the dust separation efficiency and dust separation rate, and improve the product quality of plastic particles.
