Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch production, in particular to a masterbatch drying device. Background Art

[0002] In the production process of plastic masterbatch, cooling and cutting are key steps to ensure product quality. Once the molten plastic masterbatch is extruded through the die of the extruder, it presents as continuous strip-shaped materials. At this time, the temperature is high and the form is unstable, so it must be cooled quickly and effectively to avoid possible deformation or performance degradation in subsequent processing.

[0003] Currently, the common method is to introduce a cooling water tank for rapid cooling, from a high temperature to room temperature or close to room temperature quickly. After cooling, granulation is required, so granulation is carried out at the end of the cooling water tank. However, because it is still two devices, a traction mechanism is needed when leading out the cooling water tank, which is used to lead the strip-shaped materials out of the cooling water tank and introduce them into the granulation equipment at the same time. After granulation, due to the existence of the cooling water tank, the masterbatch needs to be dried before storage.

[0004] And the current masterbatch drying methods are all to collect and dry them intensively in a drying box after granulation. In this way, after granulation, the masterbatch needs to be collected and then transferred to the drying box for drying. This process is very troublesome, not easy to automate, and has low work efficiency. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a masterbatch drying device, which solves the technical problem of low work efficiency in the existing masterbatch drying methods.

[0006] A masterbatch drying device according to the embodiments of the utility model includes an inclined net and a water storage tank arranged on the lower side of the inclined net. The inclined net inclines to one side. A flanging is provided at the edge of the inclined net. An air drying cage is provided at the lowest side of the inclined net, and a discharge port is provided at the bottom of the air drying cage;

[0007] An air drying fan is provided at the inclined net near the discharge port. The blowing direction of the air drying fan is parallel to the inclined direction of the inclined net and the blowing direction faces the discharge port;

[0008] An air drying fan for blowing air to the air drying cage is provided at the lower side position of the air drying cage.

[0009] The technical principle of the present utility model is as follows: An inclined screen is provided, and a water storage tank is arranged on the lower side of the inclined screen. When the masterbatch rolls downward along the water storage tank, some water gradually drips into the water storage tank. When it reaches the air-drying cage, since there are two air-drying fans blowing air at the masterbatch, the masterbatch rolls randomly in the air-drying cage. During this process, the moisture on the surface of the masterbatch is dried by the air-drying fans. When a certain amount of masterbatch is reached, the masterbatch near the discharge port will push against the wind of the air-drying fan and pass through the discharge port for discharging.

[0010] Compared with the prior art, the present utility model has the following beneficial effects: By means of two air-drying fans cooperating with the inclined screen with an air-drying cage and the water storage tank below it, the moisture on the surface of the masterbatch is stripped, realizing drying while conveying, and solving the technical problem of low working efficiency in the existing masterbatch drying methods.

[0011] Further, a water-blowing fan is arranged on the upper side of the inclined screen, and the blowing direction of the water-blowing fan is perpendicular to the inclined screen.

[0012] Further, steps are evenly distributed along the inclined direction on the upper edge of the inclined screen.

[0013] Further, the width of the step is 1 - 5 mm.

[0014] Further, a cooling water tank is arranged on the upper side of the inclined screen. A water pump is provided between one end of the cooling water tank and the water storage tank. The other end of the cooling water tank is provided with a water outlet. An inclined groove is arranged in the cooling water tank, and the inclined groove inclines towards the water outlet. A cutting mechanism is arranged at one end of the inclined groove close to the water outlet. The lower side of the water outlet is aligned with one side of the highest point of the inclined screen. The water-blowing fan is installed on the lower side of the cooling water tank.

[0015] Further, a water baffle is arranged between one end of the cooling water tank close to the water outlet and the water storage tank.

[0016] Further, a storage box is arranged on the lower side of the discharge port.

[0017] Further, the cross-section of the inclined screen is a concave circular arc.

[0018] Further, the cross-section of the inclined screen at the position of the air-drying cage is linear, and the cross-section of the inclined screen gradually changes from a concave circular arc to a linear shape near the air-drying cage. Description of the Drawings

Detailed implementation manners

[0025] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0026] Embodiment 1

[0027] As Figure 1 shown, the masterbatch drying device includes an inclined net 100 and a water storage tank 200 arranged on the lower side of the inclined net 100. The inclined net 100 is inclined to one side. A flanging 101 is integrally formed at the edge of the inclined net 100, and the flanging 101 is used to prevent masterbatch from falling out of the inclined net 100. The lowest side of the inclined net 100 is welded with an air-drying cage 110. A discharge port 111 is provided at the bottom of the air-drying cage 110, and a storage box 140 is provided below the discharge port 111 for receiving and storing the dried masterbatch.

[0028] As Figure 1 shown, an air-drying fan 120 is provided near the discharge port 111 of the inclined net 100. The blowing direction of the air-drying fan 120 is parallel to the inclined direction of the inclined net 100 and faces the discharge port 111, forming a wind resistance. While drying the masterbatch, the masterbatch stays at the air-drying cage 110 for a longer time to achieve sufficient drying.

[0029] As Figure 1 shown, an air-drying fan 120 that blows air towards the air-drying cage 110 is provided at the lower side position of the air-drying cage 110, giving an upward thrust to the masterbatch at the position of the air-drying cage 110, making it difficult for the masterbatch to fall out of the discharge port 111, and at the same time ensuring that each angle of the masterbatch can be fully dried.

[0030] As Figure 1As shown in the figure, a water-blowing fan 130 is provided on the upper side of the inclined mesh 100. The blowing direction of the water-blowing fan 130 is perpendicular to the inclined mesh 100, making it easier for the moisture on the surface of the masterbatch on the inclined mesh 100 to fall into the water storage tank 200.

[0031] As Figure 2 shown in the figure, steps 102 are evenly distributed along the inclined direction on the inclined mesh 100. The width of the steps 102 is 1-5 mm, causing the masterbatch to slowly roll down along the inclined mesh 100.

[0032] As Figure 3 shown in the figure, the cross-section of the inclined mesh 100 is a concave circular arc shape, and the cross-section of the inclined mesh 100 at the air-drying cage 110 is a straight line shape. The cross-section of the inclined mesh 100 gradually changes from a concave circular arc shape to a straight line shape near the air-drying cage 110. The function of the concave circular arc shape is to concentrate the masterbatch in the center for transmission, and changing to a straight line shape at the air-drying cage 110 is to enable the masterbatch to be evenly distributed in the air-drying cage 110 for drying by the air-drying fan 120.

[0033] Example 2

[0034] As Figure 4 shown in the figure, a cooling water tank 300 is provided on the upper side of the inclined mesh 100. A water pump 210 is connected by a pipeline between the water storage tank 200 and one end of the cooling water tank 300. An outlet 310 is provided at the other end of the cooling water tank 300 for the water to fall back into the water storage tank 200 again. Thus, the water storage tank 200, the water pump 210, the cooling water tank 300 and the outlet 310 form a complete water cycle.

[0035] As Figure 5 shown in the figure, an inclined groove 320 is welded and fixed in the cooling water tank 300. The inclined groove 320 inclines towards the outlet 310, used to guide the linear material and water to move towards the outlet 310 side. A cutting mechanism 330 is provided at one end of the inclined groove 320 close to the outlet 310, used to cut the strip-shaped material into granular form.

[0036] As Figure 5 shown in the figure, the end face on the side of the inclined groove 320 close to the outlet 310 is a shear end face 321. The shear end face 321 is in close contact with the cutting mechanism 330. Specifically, the cutting mechanism 330 includes a cutting motor 331, a transmission shaft 332 and a cutting edge 333. Among them, the cutting motor 331 is installed on the top of the cooling water tank 300. The rotating shaft of the cutting motor 331 is parallel to the shear end face 321. A bevel gear connection is provided between the rotating shaft of the cutting motor 331 and the transmission shaft 332. The cutting edge 333 is fixed on the transmission shaft 332. The cutting edge 333 is in close contact with the shear end face 321. Thus, a shearing force can be formed to cut the strip-shaped material. The transmission shaft 332 is provided with a bearing seat fixed on the inner side wall of the cooling water tank 300 for support.

[0037] As Figure 5As shown in the figure, a splash-proof baffle 334 is fixed to the top of the cooling water tank 300 at the cutting mechanism 330. The rotating shaft of the cutting motor 331 penetrates through the splash-proof baffle 334 and is connected to the transmission shaft 332. The splash-proof baffle 334 is used to block the water splashes lifted by the cutting edge 333 during rotation, preventing the water splashes from splashing out of the cooling water tank 300 and wetting the cutting motor 331.

[0038] As Figure 4 shown in the figure, a water-blowing fan 130 is installed on the lower side of the cooling water tank 300, which is used for air-cooling the water in the cooling water tank 300 and at the same time for drying the masterbatch on the inclined mesh 100.

[0039] As Figure 4 shown in the figure, a water baffle 220 is provided between one end of the cooling water tank 300 close to the water outlet 310 and the water storage tank 200, which is used to prevent water from splashing when it falls on the inclined mesh 100.

[0040] It realizes extruding strip-shaped materials from an extruder, cooling them through the cooling water tank 300, then cutting them into granular form by the cutting mechanism 330 to form masterbatch, then dropping from the water outlet 310 onto the inclined mesh 100 to separate water and masterbatch, and then drying through the water-blowing fan 130 and the air-drying fan 120, and finally discharging; that is, it realizes three processes of cooling, pelletizing and drying.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
