Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, and particularly relates to a particle heating and stirring device for plastic production. Background Art

[0002] Before the plastic extrusion process, it is necessary to stir the plastic particles to make them evenly mixed and improve the performance of the plastic material after production. However, in traditional production, different materials are poured into the stirring barrel, and then the mixing and stirring are carried out by a stirring mechanism.

[0003] After retrieval, the Chinese patent "a heating and stirring hopper for plastic particles" with the authorization announcement number "CN 216914450U" can heat plastic particles by setting a heating device and a turning mechanism. When there are a large number of plastic particles in the stirring tank, the rotation of the turning mechanism will cause the plastic particles to continuously turn up and down, making the plastic particles evenly heated and also evenly stirred. In this way, the plastic particles are stirred to improve the mixing degree of the plastic particles.

[0004] In the above application, the plastic particles can be stirred and heated, and the material particles can be turned over. However, affected by gravity and the turning amplitude, most of the plastic particles will settle at the bottom of the tank body, affecting the uniformity of heating.

[0005] Therefore, a particle heating and stirring device for plastic production is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a particle heating and stirring device for plastic production to solve the above problems, and improve the problem that most of the plastic particles will settle at the bottom of the tank body and the heating and stirring effect is not good.

[0007] The utility model realizes the above purpose through the following technical solutions. A particle heating and stirring device for plastic production includes:

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] When implementing: Figures 1-5 As shown, a particle heating and stirring device for plastic production includes:

[0027] A tank body 100, a de-impurity mechanism 300 is disposed at one end of the tank body 100, and a heating and stirring mechanism 200 is disposed inside the tank body 100;

[0028] Among them, the heating and stirring mechanism 200 includes a first round rod 210 rotatably connected to the other end of the tank body 100. The end of the first round rod 210 penetrates into the tank body 100. A second round rod 220 is provided at the other end of the first round rod 210. One end of the second round rod 220 sequentially penetrates the first round rod 210 and extends out of the tank body 100. Uniformly distributed stirring plates 230 are fixedly connected to the surfaces of the first round rod 210 and the second round rod 220. A motor 250 is fixedly connected to the other end of the tank body 100. Tapered gears 260 are fixedly connected to the output shaft of the motor 250, the other end of the first round rod 210, and the other end of the second round rod 220. Heating tubes 240 are arranged in the stirring plates 230.

[0029] As Figure 1 and Figure 4 shown, the impurity removal mechanism 300 includes a treatment box 310 fixedly connected to one end of the tank body 100. A blower 350 is arranged on one side of the treatment box 310. Dust suction pipes 340 are fixedly connected to the surfaces of three of the stirring plates 230. A second connecting pipe 330 is arranged in the second round rod 220. A third connecting pipe 341 is arranged between the second connecting pipe 330 and the dust suction pipes 340. A first connecting pipe 320 is arranged between the second connecting pipe 330 and the treatment box 310. One end of the second connecting pipe 330 is provided with a sealed bearing 331. The inner edge of the sealed bearing 331 is fixedly connected to the surface of one end of the first connecting pipe 320.

[0030] In this embodiment, when the blower 350 is started, the mixed gas in the tank body 100 sequentially penetrates through the filter screen 343, the dust inlet hole 342, the dust suction pipes 340, the third connecting pipe 341, and the first connecting pipe 320 and then enters the treatment box 310, and the filter plate 360 is used to isolate impurities.

[0031] As Figure 2 shown, bearings are arranged at the connection positions of the first round rod 210 and the second round rod 220. The stability of the rotation between the first round rod 210 and the second round rod 220 can be ensured.

[0032] As Figure 4 shown, a filter plate 360 is arranged inside the treatment box 310. The shape of the filter plate 360 is wavy. The wavy filter plate 360 can intercept impurities. At the same time, affected by its shape, the adhesion of dust on the surface of the filter plate 360 is reduced, and the cleaning intensity is lowered.

[0033] A box cover 311 is arranged at the top of the treatment box 310. Clamping frames 361 are arranged on the inner top wall of the box cover 311 and the inner bottom wall of the treatment box 310. Two ends of the filter plate 360 are respectively arranged in the corresponding clamping frames 361. During maintenance, the box cover 311 can be removed, and the filter plate 360 can be taken out by using the two clamping frames 361, which is more convenient for maintenance.

[0034] As Figure 4 andFigure 5 As shown, dust inlet holes 342 are evenly distributed on the surface of the dust suction pipe 340. The shape of the dust inlet holes 342 is funnel-shaped, and a filter screen 343 is provided at the opening of the dust inlet holes 342. The mutual cooperation of the funnel-shaped dust inlet holes 342 and the filter screen 343 can prevent plastic particles from entering the dust inlet holes 342 and improve the anti-blocking performance of the dust suction pipe 340.

[0035] Working principle: Place the plastic particles into the tank body 100. After the placement is completed, start the motor 250. Under the mutual meshing action of the three bevel gears 260, the first round rod 210 and the second round rod 220 rotate in opposite directions, so as to realize that the first round rod 210 and the second round rod 220 drive the stirring plate 230 to rotate in the tank body 100. The two groups of stirring plates 230 on the first round rod 210 and the second round rod 220 will rotate in opposite directions, throwing up the plastic materials in the tank body 100, and using the heating pipe 240 to heat the stirring plate 230, realizing the heating operation of the plastic particles during the stirring process. At the same time, during the heating and stirring process, start the fan 350 at the same time, so that the mixed gas in the tank body 100 sequentially passes through the filter screen 343, the dust inlet holes 342, the dust suction pipe 340, the third connecting pipe 341, and the first connecting pipe 320 and then enters the treatment box 310, and uses the filter plate 360 to isolate impurities.

[0036] It should be noted that in the above description, the motor 250, the sealed bearing 331, the fan 350, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the motor 250 and the fan 350 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0037] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
