[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a stirring device, including a cylinder, a stirring assembly, a driving component, and an air pump; the top of the cylinder has an upward-facing cavity; the stirring assembly includes a stirring shaft, a stirring plate located on the stirring shaft, and a spray nozzle communicating with the stirring shaft; the driving component is installed above the cylinder and is drivenly connected to the stirring shaft; the air pump is located on one side of the driving component and is communicating with the spray nozzle.

[0007] In some embodiments, at least four jet nozzles are symmetrically distributed on the stirring shaft.

[0008] In some embodiments, the spray direction of the nozzles on different sides is different.

[0009] In some embodiments, the nozzle has at least six air jet holes at its air outlet.

[0010] In some embodiments, the stirring shaft is hollow, and the air pump is connected to the stirring shaft via a flexible hose.

[0011] In some embodiments, the stirring plate includes two detachably connected sub-plates.

[0012] In some embodiments, at least four stirring plates are provided, and each stirring plate is arranged vertically.

[0013] In some embodiments, an upper support is mounted at the opening of the cavity, and both the drive unit and the air pump are fixedly connected to the upper support.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] To address the technical problem of low overall mixing efficiency, this invention provides a mixing device that can improve mixing efficiency.

[0024] It should be noted that the stirring device of this utility model is used for, but not limited to, stirring of plastic granules. For ease of explanation, this utility model only uses an example of a stirring device applied to a plastic granule stirring device. The principle of a stirring device applied to other types of equipment is essentially the same as that applied to a plastic granule stirring device, and will not be described in detail here.

[0025] Please see Figures 1-3 , Figure 1 This is a schematic diagram of a stirring device according to an embodiment of the present invention. The stirring device includes a cylinder 100, a stirring assembly 200, a driving component 300, and an air pump 400. The top of the cylinder 100 has an upward-facing cavity 110. The stirring assembly 200 includes a stirring shaft 210, a stirring plate 220 located on the stirring shaft 210, and a spray nozzle 230 communicating with the stirring shaft 210. The driving component 300 is installed above the cylinder 100 and is connected to the stirring shaft 210 in a driving connection. The air pump 400 is located on one side of the driving component 300 and is connected to the spray nozzle 230.

[0026] In this embodiment, a basic stirring structure is constructed by setting a stirring plate 220. Furthermore, by using a nozzle 230 connected to the stirring shaft 210 and an air pump 400 connected to the nozzle 230, the nozzle 230 can blow plastic particles to more layers over a wider range as it rotates with the stirring shaft 210, providing conditions for faster and farther layer flow of plastic particles. This avoids the possible adhesion of a small number of plastic particles and makes the flow of plastic particles more sufficient, thereby making the stirring more uniform and directly improving the overall stirring efficiency.

[0027] In one embodiment, please refer to Figure 3 At least four nozzles 230 are symmetrically distributed on the stirring shaft 210.

[0028] In this embodiment, the multiple configurations of the spray nozzle 230 allow for more flow stages of the plastic particles, resulting in better mixing.

[0029] In one embodiment, please refer to Figure 3 The spray direction of the nozzles 230 on different sides is different.

[0030] In this embodiment, the spray directions of the nozzles 230 on different sides are different, which helps to improve the uniformity of stirring and also avoids the sticking of plastic particles.

[0031] In one embodiment, please refer to Figure 3 The nozzle 230 has at least six jet holes 231 at its air outlet.

[0032] In one embodiment, please refer to Figure 1 The stirring shaft 210 is hollow, and the air pump 400 is connected to the stirring shaft 210 through a hose 410.

[0033] In this embodiment, the length of the hose 410 should not be too long. The drive component 300 only drives the stirring component 200 to reciprocate at a large angle. In order to avoid disorderly rotation of the hose 410, a relatively loose limit can be set by a rope to ensure normal gas flow.

[0034] In one embodiment, please refer to Figure 3 The mixing plate 220 includes two detachably connected sub-plates 221.

[0035] In this embodiment, the sub-boards 221 are connected by pins.

[0036] In one embodiment, please refer to Figure 3 At least four stirring plates 220 are provided, and each stirring plate 220 is arranged vertically.

[0037] In one embodiment, please refer to Figure 1 An upper bracket 120 is mounted at the opening of the cavity 110, and the drive unit 300 and the air pump 400 are both fixedly connected to the upper bracket 120.

[0038] In this embodiment, plastic particles enter the cylinder 100 through the gap between the upper support 120 and the cavity 110.

[0039] In one embodiment, please refer to Figure 2 The bottom end of the cylinder 100 is provided with a bearing seat 130 and a bearing cover 140. The bearing seat 130 is connected to the bottom end of the stirring shaft 210. The bearing cover 140 is placed on the bearing seat 130.

[0040] In one embodiment, please refer to Figure 1 , Figure 2 The bottom of the cylinder 100 is equipped with at least three cylinder feet 150. A side door 160 that can be opened and closed is provided on one side of the bottom of the cylinder 100. The side door 160 is used for unloading and maintenance.

[0041] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:

[0042] First, plastic granules are poured into the cylinder 100 through the upper part of the cavity 110. Then, the drive unit 300 and the air pump 400 are activated, driving the stirring shaft 210 to rotate reciprocally and the nozzle 230 to spray air outwards, respectively. During this process, the plastic granules are agitated by the stirring plate 220 and affected by the airflow from the nozzle 230. The plastic granules will not be confined to adjacent layers but will flow across more and farther layers, thereby improving the mixing effect and ultimately increasing the overall mixing efficiency. It should be noted that the speed of the airflow is such that the plastic granules are not damaged.

[0043] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
