Description

Technical Field

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

[0002] Masterbatch is a plastic colorant made of a high proportion of pigments or additives and thermoplastic resins that are well dispersed. The selected resin has good wetting and dispersing effects on the colorant and has good compatibility with the colored material. Masterbatch generally consists of three parts: colorant, carrier and dispersant. It is mixed in a high-speed mixer, crushed, extruded and pulled into granules. In the plastic processing process, the generally used technology is the wet process. The masterbatch material is ground in water phase, inverted, washed, dried and granulated. Only in this way can the product quality be guaranteed.

[0003] The traditional masterbatch drying device includes a frame and a storage tank. The storage tank is installed on the frame, and a hot air blower for blowing hot air to the storage tank is provided on the frame. The hot air blower outlet is connected to an air outlet pipe, and the air outlet pipe extends into the storage tank, thereby drying the masterbatch in the storage tank by hot air.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: since the masterbatches are accumulated in the storage tank, the masterbatches in the storage tank are dried only by blowing hot air, which may cause some of the masterbatches to be heated unevenly, resulting in poor drying effect. The general solution is to install a stirring device on the storage tank to stir the masterbatches in the storage tank so that the masterbatches move, thereby improving the air-drying effect. However, since the masterbatch is relatively moist, it is easy to stick to the inner wall of the storage tank while stirring, and the staff needs to constantly clean the inner wall of the storage tank, which seriously affects the work efficiency.

[0005] Therefore, we propose a masterbatch pressure drying device. Utility Model Content

[0006] The purpose of the utility model is to provide a masterbatch drying device to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A masterbatch drying device comprises a drying box, wherein both sides of the drying box are provided with sockets, a guide plate is installed through the inner cavity of the socket, a wind hole is opened on the top of the guide plate, a bottom cover is installed on the top of the drying box, and a pipeline for connecting to a hot air blower is arranged on the side of the bottom cover.

[0009] Preferably, there is a height difference between the two sockets, the socket on the left side is higher than the socket on the right side, and the longitudinal height of the socket is greater than the thickness of the guide plate.

[0010] Preferably, a hopper is installed on the left side of the drying box through fasteners, a recess is opened on the right side wall of the hopper, and a sealing plate is inserted into the inner cavity of the recess.

[0011] Preferably, a baffle structure is fixedly mounted on the inner wall of the bottom cover, a notch is provided at the bottom of the baffle structure, and a height of the notch gradually decreases from left to right.

[0012] Preferably, a fixed shaft is installed through the inner cavity of the socket on the left side, and a hollow cylinder with a paddle is mounted on the outer ring of the fixed shaft.

[0013] Preferably, a top cover is installed on the top of the drying box, and a pipeline for docking with the exhaust gas recovery equipment is arranged on the side of the top cover.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The masterbatch drying device uses an inclined guide plate, an inclined conical hole-shaped air hole and a hot air flow flowing from bottom to top. When the masterbatch is initially wet and sticky to the guide plate, its drying time can be increased and it can be fully dried. After the drying is completed, it loses its stickiness and can be blown up by the hot air flow, flowing along the guide plate and being collected. In the whole process, the masterbatch has no other additional force except the wind force, which can ensure the integrity and quality of the masterbatch.

[0016] 2. The masterbatch drying device can utilize hot air more effectively through the design of the baffle structure. The masterbatch on the left side of the guide plate is more humid than that on the right side, so more hot air is needed for drying. As the drying process continues, the masterbatch on the right side requires less heat, so full utilization of heat can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] The utility model provides a technical solution for a masterbatch drying device:

[0025] Example:

[0026] The drying device mainly comprises a drying box 1, such as Figure 1 , Figure 2 and Figure 3 As shown, a socket 2 is provided at both sides of the drying box 1, a guide plate 3 is inserted into the inner cavity of the socket 2, and the bottom of the guide plate 3 is fixed to the bottom of the inner wall of the socket 2 by screws or glue bonding. The socket 2 is not only used to plug and fix the guide plate 3, but also the longitudinal height of the socket 2 is greater than the thickness of the guide plate 3, and the two sockets 2 also serve as the inlet and outlet of the masterbatch.

[0027] like Figure 2 and Figure 4 As shown, a wind hole 4 for hot air flow to pass through is opened on the surface of the guide plate 3, and the wind control 4 is a conical hole with a small-diameter end facing the top of the guide plate 3, and the wind hole 4 and the guide plate 3 are both in an inclined state, and the central axis of the wind hole 4 is perpendicular to the guide plate 3.

[0028] like Figure 1 and Figure 2 As shown, a bottom cover 5 is installed at the bottom of the drying box 1 through fasteners, and the bottom cover 5 is connected to the blower through a pipeline to transport hot air for drying the masterbatch from the bottom into the drying box 1.

[0029] Among them, Figure 1 and Figure 2 As shown, a hopper 7 is installed on the left side of the drying box 1. Figure 5 As shown, a notch 8 is provided on the right end surface of the hopper 7, and a sealing plate 9 is clamped in the notch 8.

[0030] The bottom of the hopper 7 and the bottom of the sealing plate 9 are both in contact with the top of the guide plate 3 to achieve sealing.

[0031] A top cover 13 is also provided on the top of the drying box 1. When in use, an activated carbon filter structure, for example, can be placed in the inner cavity of the top cover 13 to purify the waste gas generated by drying the masterbatch.

[0032] In this embodiment, when the device is used to dry the masterbatch, the hot air is first blown into the drying box 1 through the external blower structure, and the inner cavity of the drying box 1 and the guide plate 3 are preheated. Then, the sealing plate 9 is removed, and the masterbatch temporarily stored in the hopper will enter the inner cavity of the drying box 1 from the left socket 2 along the upper surface of the guide plate 3. In this technical solution, since the guide plate 3 adopts an inclined design, the masterbatch product can roll and flow along the guide plate 3. When the masterbatch enters After entering the inner cavity of the drying box 1, the hot air always flows upward from the bottom of the guide plate 3, and then penetrates the guide plate from the air hole 4. On the one hand, the guide plate 3 is continuously heated, and on the other hand, the hot air passing through the air hole 4 directly acts on the masterbatch. At this time, the guide plate 3 and the hot air directly acting on the masterbatch can dry and dehydrate the masterbatch. After drying, the masterbatch will lose its adhesive force with the guide plate 3, and can flow along the inclined surface of the guide plate 3 to the socket 2 on the right side to flow out with the hot air.

[0033] Embodiment 2:

[0034] The baffle structure 6 is installed on the inner wall of the bottom cover 5 at equal distances, and a notch is provided at the bottom of the baffle structure 6, that is, there is a certain distance between the bottom of the baffle structure 6 and the inner wall of the bottom cover 5, and Figure 2 As shown, the size of the notch decreases gradually from left to right.

[0035] In this embodiment, based on the embodiment 1, hot air enters from the pipe on the side of the bottom cover 5. Since the pipe is in a horizontal state, the hot air will first contact the baffle structure 6, and part of the hot air is blocked and changes direction to flow upward until it hits the guide plate 3, and another part slips out of the notch and hits the next baffle structure 6, and so on, until it reaches the left and right ends of the inner cavity of the drying box 1. Through the design of the baffle structure 6, the hot air can be used more effectively. The masterbatch on the left side of the guide plate 3 is more humid than that on the right side, so more hot air is needed for drying. As the drying process continues, the masterbatch to the right requires less heat, so that full utilization of heat can be achieved.

[0036] Embodiment 3:

[0037] like Figure 3 and Figure 4As shown, a fixed shaft 10 is inserted into the inner cavity of the left socket 2, a hollow cylinder 11 is mounted on the outer ring of the fixed shaft 10, a paddle 12 is arranged on the outer wall of the hollow cylinder 11, and the paddle 12 at the rightmost position extends into the inner cavity of the drying box 1, and the paddle 12 contacts the bottom of the inner wall of the left socket 2 when rotating.

[0038] In this embodiment, based on Embodiment 1 and Embodiment 2, after the hot air passes through the air hole 4, part of the hot air will blow on the paddle 12, and the paddle 12 will drive the hollow cylinder 11 to rotate synchronously, and the masterbatch products entering the socket 2 will be transported to the inner cavity of the drying box 1 in batches in sequence, so as to avoid accumulation caused by too much entering at one time, which will affect the drying work of the masterbatch.
