Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and in particular to a plastic granule mixer. Background Technology

[0002] When producing plastic products, the plastic particles must first be mixed before processes such as blown film, hot pressing, or injection molding are performed. Generally, a mixing tank is used to thoroughly mix the plastic particles inside.

[0003] During the mixing process, plastic particles collide back and forth, causing plastic powder to detach from the outside of the particles. This detached plastic powder also affects the mixing tank, resulting in each new batch of plastic particles being contaminated with a lot of powder, which has a negative effect on subsequent processing and, in severe cases, can affect the production process.

[0004] The utility model patent "Plastic Granule Mixer" with authorization announcement number CN220389960U proposes a method to adsorb and collect dust generated during the mixing of plastic granules to avoid affecting subsequent work. However, because the friction of the plastic granules continues until they are discharged, some powder will still be discharged with the material. Although the powder is cleaned, the amount remaining will still have an impact.

[0005] Therefore, a mixing machine is needed that can clean and centrally process plastic powder before discharge to minimize the amount of impurities carried by plastic particles. Utility Model Content

[0006] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide a plastic granule mixer that can store plastic dust and minimize the amount of dust carried before discharge.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A plastic granule mixer includes a mixer body, a discharge shell fixedly connected to the lower part of the mixer body, and a dust collection box installed below the discharge shell. The discharge shell is in communication with the interior of the mixer body and the dust collection box. A filter screen for filtering dust is inclinedly arranged inside the discharge shell. The mixer body is provided with a dust collection chamber for separating dust.

[0009] The dust collection chamber is connected to a first dust suction pipe and a second dust suction pipe for connecting the inside of the dust storage box. The mixing machine body is provided with a first dust removal component for collecting dust in the dust storage box.

[0010] Furthermore, the mixer body has a cavity, and a discharge port is connected above the cavity. The mixer body includes a screw feeder installed in the cavity.

[0011] Furthermore, the mixing machine body is provided with a first connecting pipe for connecting the cavity and the dust collection chamber, and the first connecting pipe is provided with a one-way valve that allows air to flow from the cavity to the dust collection chamber only.

[0012] Furthermore, the first dust removal component includes a first suction pipe that connects the dust collection chamber and the dust storage box, and a second suction pipe that connects the cavity and the dust storage box.

[0013] Furthermore, the mixing machine body is provided with a first suction pump for drawing air through a first suction pipe, and the mixing machine body is provided with a second suction pump for drawing air through a second suction pipe.

[0014] Furthermore, the discharge housing is provided with a connecting cavity, which is used to connect the cavity and the dust storage box. The dust storage box is provided with a discharge port, and a blower is installed inside the discharge port facing the filter screen.

[0015] Furthermore, a second connecting pipe is installed on the mixing machine body to connect the dust storage box and the connecting cavity.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention can repeatedly extract internal plastic dust during mixing and store the plastic dust in one location for later processing. Furthermore, through multiple dust removal processes, the amount of dust carried over can be minimized before discharge, resulting in higher quality plastic particles upon discharge and providing convenience for subsequent processing steps.

[0023] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1 to 4 This embodiment provides a plastic granule mixer, including a mixer body 11. The mixer body 11 has a cavity 21 inside, and a discharge port 15 is connected above the cavity 21. The mixer body 11 includes a screw feeder 22 installed in the cavity 21. The mixer body 11 is provided with a first connecting pipe 18 for connecting the cavity 21 and the dust collection chamber 26. The first connecting pipe 18 is provided with a one-way valve 19 that allows air to flow from the cavity 21 to the dust collection chamber 26.

[0025] Plastic granules to be mixed are added into cavity 21 through discharge port 15. During the addition process, the dust is treated by the first suction pipe 12 and the second suction pipe 16 connected to the dust storage box 13 in the dust collection chamber 26. The dust generated during the addition of plastic granules can be adsorbed by the second suction pipe 16. When adsorbing by the first suction pipe 12, the air in the dust collection chamber 26 needs to be extracted. Therefore, the air can be drawn in through the first connecting pipe 18 with one-way valve 19 to replenish the dust collection chamber 26 and avoid air pressure problems.

[0026] The discharge housing 14 is fixedly connected to the lower part of the mixer body 11. The discharge housing 14 is in communication with the interior of the mixer body 11 and the dust storage box 13. The discharge housing 14 is provided with a filter screen 24 for filtering dust at an incline. The mixer body 11 is provided with a dust collection chamber 26 for separating dust.

[0027] The inclined filter screen 24 allows the plastic particles to move toward the discharge port 15.

[0028] The mixing machine body 11 is provided with a first dust removal component 27 for collecting dust in the dust storage box 13. The first dust removal component 27 includes a first suction pipe 12 that is connected between the dust collection chamber 26 and the dust storage box 13, and a second suction pipe 16 that is connected between the cavity 21 and the dust storage box 13.

[0029] The mixing machine body 11 is provided with a first air pump 17 for drawing air through the first dust suction pipe 12, and the mixing machine body 11 is provided with a second air pump 25 for drawing air through the second dust suction pipe 16.

[0030] By activating the first suction pump 17, the first suction pipe 12 can be driven to perform adsorption, and by activating the second suction pump 25, the second suction pipe 16 can be driven to perform adsorption.

[0031] The discharge housing 14 is provided with a connecting cavity 23, which is used to connect the cavity 21 and the dust storage box 13. The dust storage box 13 is provided with a discharge port 15. A blower 30 is installed inside the discharge port 15 facing the filter screen 24. The mixing machine body 11 is provided with a second connecting pipe 29 for connecting the dust storage box 13 and the connecting cavity 23.

[0032] The blower 30 can blow fly ash to the bottom of the filter screen 24 as the plastic particles slide down, and some of the fly ash can fly into the dust collection box 13 through the second connecting pipe 29.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
