Description

Technical Field

[0001] The utility model relates to the technical field of reducing dust, in particular to a device for reducing dust of EVA products. Background Art

[0002] The molten material of photovoltaic grade V2825 produced by the EVA tubular method device enters the main extruder 22-PK-1701-EX-1701 from the bottom feeding section of the 22-V-1402 tank, where the feeding section is heated by medium-pressure steam at 180°C. The molten polyethylene enters the feeding section of the extruder 22-PK-1701-X-1701 from the extrusion hopper. The extrusion is heated by high-pressure steam (when producing LDPE) or low-pressure steam (when producing EVA). The high-temperature template can prevent the reactants from solidifying and clogging the die holes when passing through the die holes. The barrel part of the extruder uses barrel water at about 80°C for heat removal. The molten material passing through the die holes is cut by the underwater pelletizer 22-PK-1701-X-1703. The pelletized particles are sent to the back system through pellet water at about 12°C.

[0003] When the EVA tubular device produces EVA grades, the particle water system provides cooling water to quickly cool the cut particles and then send them to the dryer. The cooling water and part of the powder return to the particle water tank, and the foam will float on the surface of the particle water tank. The original particle water tank is equipped with a baffle plate, and the floating foam overflows from the surface of the baffle plate to achieve the purpose of skimming. However, the actual situation is that it is difficult for the foam to overflow. After a long time, the surface foam accumulates seriously and is brought into the particle water system. After continuous circulation, it enters the pelletizing water chamber and enters the silo with the particles, resulting in the dust content in the particles being affected. In view of this, a device for reducing the dust content of EVA products is proposed. Utility Model Content

[0025] Example: See Figure 1-Figure 4 As shown, this embodiment provides a device for reducing the dust content of EVA products, including a water tank 1, a water reservoir of the water tank 1 is provided with a flapping component 3, a cleaning component 4 is installed on one side of the flapping component 3, a baffle 2 is provided in the inner cavity of the water tank 1, a notch is opened in the middle part of the upper end of the baffle 2, and the floating foam in the water reservoir can be discharged through the notch, and the cleaning component 4 is used to scrape off the floating foam on the side wall of the baffle 2 close to the flapping component 3.

[0026] The flapping assembly 3 includes a power assembly, which includes a first protective shell 311. The first protective shell 311 is fixedly mounted on the inner cavity side wall of the water tank 1. The first protective shell 311 is embedded with a motor 312. The first protective shell 311 prevents water in the water tank 1 from entering the motor 312, affecting normal use and extending the service life of the motor 312. The output shaft of the motor 312 is fixedly connected with a rotating shaft 313. When the motor 312 is started, the output shaft of the motor 312 drives the rotating shaft 313 to rotate, and the rotating shaft 313 is through-plugged with a limit plate 314. The limit plate 314 gives support force to the rotating shaft 313 on the one hand, and does not hinder the rotation of the rotating shaft 313 on the other hand. A fan blade 315 is fixedly mounted on one end of the rotating shaft 313 away from the motor 312. The rotating rotating shaft 313 drives the fan blade 315 to start rotating. Driven by the huge rotating force, the water in the water tank 1 surges up and violently hits the side wall of the water tank 1, causing the foam on the water surface to enter the notch of the baffle 2.

[0027] A transmission component is provided on the upper side of the power component, and the transmission component includes a pulley 321. The pulley 321 is fixedly connected to the rotating shaft 313, and the rotating shaft 313 passes through the pulley 321. When the rotating shaft 313 rotates, the rotating shaft 313 and the pulley 321 rotate together due to the fixed connection with the rotating shaft 313. The rotating shaft 313 passes through the outer walls of both ends of the pulley 321 and is fixedly connected with a turntable 322. The outer wall of the pulley 321 is sleeved with a transmission belt 323. The pulley 321 and the turntable 322 are also provided on the upper side of the inner cavity of the transmission belt 323. The size of the turntable 322 is higher than the pulley 321 to ensure that the transmission belt 323 will not fall off accidentally during movement.

[0028] A groove is provided in the inner side wall of the water tank 1, and a connecting shaft 33 is clamped in the groove. The connecting shaft 33 is fixedly connected to the pulley 321 on the upper side of the inner side of the transmission belt 323. The transmission belt 323 drives the upper pulley 321 to rotate, that is, the connecting shaft 33 can rotate and rotate together with the pulley 321. The end of the connecting shaft 33 away from the water tank 1 is fixedly connected to the disk 34. At the same time, the connecting shaft 33 causes the disk 34 to rotate. The disk 34 is symmetrically on the side wall away from the connecting shaft 33. An L-shaped tube 35 is installed, and a beating ball 36 is fixedly installed at one end of the horizontal part of the L-shaped tube 35. The L-shaped tube 35 on the disc 34 will rotate with the disc 34. At this time, the two beating balls 36 take turns to beat the water surface, making the already surging water surface, and the floating foam on the water surface flows toward the groove of the baffle 2 under the impact of the beating balls 36, thereby reducing the residual foam in the water tank (1), and then reducing the content of the foam brought into the particle system, that is, reducing the amount of dust in the particles.

[0029] The cleaning assembly 4 includes a second protective shell 41 fixed to the bottom of the water tank 1, and the second protective shell 41 is embedded with a cylinder 42. The second protective shell 41 prevents water in the water tank 1 from entering the cylinder 42, affecting normal use and extending the service life of the cylinder 42. The piston shaft of the cylinder 42 is fixedly connected with a telescopic rod 43, and the end of the telescopic rod 43 away from the cylinder 42 is fixedly connected with a scraper 44. The telescopic rod 43 supports the scraper 44 while extending or shortening. The cylinder 42 drives the telescopic rod 43 to extend and retract to push the scraper 44 to scrape off the foam on the side wall of the baffle 2. The scraper 44 is trapezoidal as a whole. The scraper 44 is used to scrape off the foam on the side wall of the baffle 2. The trapezoidal scraper 44 is more suitable for the baffle 2 with grooves, and can more easily scrape off the foam on the side wall of the baffle 2.

[0030] A fixing plate 5 is fixedly installed at the bottom of the water tank 1 and on one side wall of the baffle 2 away from the flapping assembly 3. The fixing plate 5 is in the shape of a triangular prism as a whole. Two vertical side walls of the triangular prism-shaped fixing plate 5 are fixed to the side wall in contact with the baffle 2 and the water tank 1. When water and foam flow in through the groove, they quickly flow out along the inclined side wall of the fixing plate 5.

[0031] When the device for reducing the dust content of EVA products of this embodiment is used, the fan blades 315 are driven to rotate by the motor 312, so that the water in the water tank 1 violently surges. At the same time, the two beating balls 36 are driven by the transmission component to further impact the water in the water tank 1, so that the degree of water surge is further increased, so that the foam in the water tank 1 flows out through the groove of the baffle 2 together with the water, reducing the foam brought into the particle water system, and entering the pelletizing water chamber after continuous circulation, and entering the silo along with the particles, thereby reducing the dust content in the particles.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
