Description

Technical Field

[0001] The invention relates to the field of masterbatch processing equipment, and more specifically to a masterbatch dispersing and drying equipment. Background Art

[0002] The full name of masterbatch is masterbatch, also called color seed. It is a new type of colorant specially used for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an extraordinary amount of pigment into the resin, which can be called pigment concentrate, so its tinting power is higher than the pigment itself.

[0003] During the processing of masterbatches, the masterbatches need to be dried. When drying, the traditional stirring and drying equipment cannot make sufficient contact between the hot air flow and each particle due to the stacking of masterbatch particles. This causes some particles to be over-dried and others to be under-dried, resulting in uneven drying.

[0004] The present application provides a masterbatch dispersion and drying device, which allows the airflow to fully contact the masterbatch particles, thereby ensuring the uniformity and sufficiency of drying. Summary of the invention

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) The present invention uses a synchronously rotating lifting plate and a guide plate to lift the masterbatch in the drying cylinder and make the lifted masterbatch particles roll down along the material rolling channel line formed between the lifting plate and the guide plate. At the same time, a hot air flow is injected into the material rolling channel through an air inlet fixed cylinder and an air outlet mesh plate, so that the hot air flow and the masterbatch particles rolling down flow in the opposite direction, so that the air flow is in full contact with all surfaces of the masterbatch particles, and the air flow is forced to be in full contact with the masterbatch in the narrow and long material rolling channel, so that all parts of the masterbatch are dried more evenly and fully, and the drying efficiency is improved.

[0021] (2) The present invention is provided with a plurality of groups of lifting plates distributed in a circumference and guide plates with a horizontal S-shaped cross-section, so that the excess masterbatch that has not entered the lifting material rolling channel rolls down through the upper end surface of the guide plate into the next group of material rolling channels to be lifted, thereby ensuring that each part of the masterbatch is in contact with the hot air flow.

[0022] (3) The present invention is provided with a fixed air inlet cylinder with a fan-shaped air outlet groove and a rotating cylinder equipped with a fan-shaped air outlet mesh plate, so that when the rotating cylinder drives the material rolling channel to rotate to the upper right side of the drying cylinder, the hot air flow will be injected into the material rolling channel, thereby avoiding the hot air flow from flowing randomly, ensuring the convection movement of the material flow and the hot air flow, and improving the drying effect and drying speed.

[0023] (4) The present invention is provided with a floating block installed on the lifting plate and capable of floating up and down movement. When the masterbatch rolls in the material rolling channel, the masterbatch particles are impacted and lifted by the floating block, so that the masterbatch is suspended in the air and contacts the hot air flow, thereby further improving the contact effect between the hot air flow and the masterbatch. At the same time, the floating block prevents the masterbatch from rolling downward, thereby prolonging the contact time between the hot air flow and the masterbatch, thereby ensuring thorough drying.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] See also Figure 1-10 In one embodiment of the present invention, a masterbatch dispersion drying device includes a drying cylinder 1, wherein a lifting plate 2 is arranged in a circumferentially equidistantly distributed manner in the drying cylinder 1, a rotating cylinder 3 is fixedly connected to the inner side of the lifting plate 2, and a fixed air inlet cylinder 4 rotatably connected to the rotating cylinder 3 is nested in the inner side of the rotating cylinder 3; a material drop chute 201 is provided on the side of the lifting plate 2 close to the rotating cylinder 3, a guide plate 7 fixedly connected to the rotating cylinder 3 is fixedly connected above the lifting plate 2, and a material rolling channel communicating with the material drop chute 201 is formed between the guide plate 7 and the lifting plate 2; the rotating cylinder 3 extends to the rear side of the drying cylinder 1 and is connected to a driving motor 6 through a first transmission gear set 5;

[0042] The rotating cylinder 3 is nested with multiple groups of air outlet mesh plates 301 corresponding one by one to the blanking grooves 201, and the upper right part of the fixed air inlet cylinder 4 is provided with an air outlet groove 401 that cooperates with the air outlet mesh plate 301. When the rotating cylinder 3 rotates to the upper right part of the fixed air inlet cylinder 4, the air vents of the air outlet mesh plate 301 are connected with the air outlet groove 401; the fixed air inlet cylinder 4 extends to the rear side of the rotating cylinder 3 and is connected with an air inlet pipe 8, and the air inlet pipe 8 is connected with a hot air blower 9.

[0043] Specifically, when the masterbatch is dried, the masterbatch put into the drying cylinder 1 is gathered at the bottom of the drying cylinder 1, and the driving motor 6 drives the rotating cylinder 3 to rotate through the first transmission gear set 5, and the rotating cylinder 3 drives the lifting plate 2 and the guide plate 7 thereon to make a circular motion. When the lifting plate 2 lifts the masterbatch along the inner wall of the drying cylinder 1 to above the horizontal position, the masterbatch rolls along the upper end surface of the lifting plate 2 under the action of gravity, and the masterbatch enters the material rolling channel between the guide plate 7 and the lifting plate 2, and finally falls from the drop chute 201; when the masterbatch is in the material rolling channel, the hot air generated by the hot air blower 9 is injected into the fixed air inlet cylinder 4 through the air inlet pipe 8, and the hot air flows through the air outlet trough 401 and the air outlet mesh plate 3 01 mesh enters the blanking chute 201, and then flows upward along the material rolling channel under the action of its own lift, and fully contacts the masterbatch rolling down. The material rolling channel limits the flow range of the airflow, and forces the hot airflow to fully contact the various surfaces of the tumbling masterbatch particles, so that the drying is sufficient. At the same time, the material flow and the hot airflow containing moisture move in opposite directions, so that the moisture is taken away faster, thereby improving the drying efficiency. At the same time, as the rotating cylinder 3 drives the lifting plate 2 and the guide plate 7 to rotate continuously, the next group of lifting plates 2 and the guide plate 7 circulate and dry the masterbatch dropped by the previous group, so that the circulated drying of the masterbatch can be realized without repeated loading and unloading, thereby ensuring more thorough drying.

[0044] See also Figure 3 In this embodiment, the drying cylinder 1 is a horizontally arranged hollow cylinder, a feeding pipe 10 is connected to the upper left of the drying cylinder 1, the feeding pipe 10 is hinged with a movable cover plate, a discharge door plate 11 with a lock is hinged at the bottom of the drying cylinder 1, and an exhaust pipe 12 is connected to the top of the drying cylinder 1.

[0045] Specifically, it is convenient for the rapid feeding and discharging of masterbatch and the discharge of water vapor.

[0046] In this embodiment, the lifting plate 2 is a horizontal rectangular plate and its outer end surface is in sliding contact with the inner wall of the drying cylinder 1 .

[0047] Specifically, the masterbatch is lifted upward by the lifting plate 2 and the inner wall of the drying cylinder 1 , so as to prevent the masterbatch from remaining at the bottom of the drying cylinder 1 .

[0048] See also Figure 4 In this embodiment, the side of the material drop chute 201 away from the rotating cylinder 3 is an arc-shaped surface, and the part of the guide plate 7 located above the material drop chute 201 is also an arc-shaped surface.

[0049] Specifically, the material and the hot air flow are made to flow in a staggered manner at the position of the material drop chute 201, so as to prevent the material from blocking the air flow from flowing above the masterbatch.

[0050] See also Figure 3 and Figure 5-9In this embodiment, the rotating cylinder 3 is a hollow cylinder arranged longitudinally and opened at both ends. A mounting groove for mounting an air outlet mesh plate 301 is provided on the rotating cylinder 3. The air outlet mesh plate 301 is fixedly connected to the inner wall of the mounting groove by bolts.

[0051] Specifically, it is convenient to disassemble and clean the air outlet mesh plate 301.

[0052] In this embodiment, the fixed air inlet cylinder 4 is a hollow cylinder arranged longitudinally and opened at the rear end, the air outlet groove 401 is a fan-shaped through groove, the air outlet mesh plate 301 is an arc-shaped mesh plate, and the curvature of the air outlet groove 401 is greater than the curvature of the air outlet mesh plate 301.

[0053] Specifically, when each set of air outlet mesh plates 301 rotates to the position of the air outlet slot 401, the hot air flow passes through the air outlet slot 401 and the air outlet mesh plates 301 into the material drop trough 201 and the material rolling channel. When the rotating cylinder 3 rotates at the upper right part of the fixed air inlet cylinder 4, the hot air flow keeps flowing, realizing continuous hot air flow injection, ensuring that the masterbatch keeps in contact with the air flow during the rolling process.

[0054] See also Figure 8 In this embodiment, the guide plate 7 is a bent plate with a horizontal S-shaped cross section, and an arc-shaped upward portion is provided at the outer end of the guide plate 7.

[0055] Specifically, it makes it easier for the masterbatch to enter the material rolling channel during the lifting process; in addition, when the number of masterbatch is large, in the process of synchronous rotation of multiple groups of lifting plates 2 and guide plates 7, when the group of lifting plates 2 and guide plates 7 located on the right side being lifted are lifted, some masterbatch does not enter the material rolling channel of this group but rolls onto the upper end surface of the guide plate 7. After the guide plate 7 rotates, this part of the masterbatch falls into the material rolling channel on the left side and flows into the drying cylinder 1 and accumulates on the inner side of the left group of lifting plates 2. When the left group of lifting plates 2 and guide plates 7 are lifted, the masterbatch of the previous group that has not been dried is lifted first to enter the material rolling channel for drying, thereby ensuring that the masterbatch at each position can contact with the hot air flow and improving the uniformity of drying.

[0056] See also Figure 10-13In another embodiment of the present invention, a plurality of groups of floating blocks 13 are installed on the lifting plate 2, which are equidistantly distributed along the length direction and arranged longitudinally. The lifting plate 2 is provided with a mounting cavity 202 for the floating blocks 13 to move up and down. The inner end of the floating block 13 is fixedly connected with a clamping frame 14 extending into the mounting cavity 202. The clamping frame 14 is clamped with an eccentric groove disk 15. The eccentric groove disk 15 is fixedly connected with a longitudinal axis 16 extending to the front end of the lifting plate 2. The front end of the longitudinal axis 16 is connected with a transverse axis 17 through a second transmission gear set. The transverse axis 17 is fixedly connected with a rolling gear 18 at one end close to the fixed air intake cylinder 4. The rolling gear 18 is meshed with a fixed gear ring 19 fixedly sleeved with the fixed air intake cylinder 4.

[0057] Specifically, during the rotation of the lifting plate 2, the rolling gear 18 rolls on the fixed gear ring 19, and the rolling gear 18 drives the eccentric groove disk 15 to rotate through the transverse shaft 17 and the longitudinal shaft 16. The eccentric groove disk 15 drives the floating block 13 to move up and down through the clamping frame 14. During the rolling of the masterbatch on the surface of the lifting plate 2, the floating block 13 floating up and down impacts the rolling masterbatch at high speed, lifts the masterbatch in the material rolling channel, so that the hot air flow is fully in contact with the lifted masterbatch, further improves the contact effect between the air flow and each surface of the masterbatch, and improves the uniformity and thoroughness of drying; at the same time, the lifted floating block 13 blocks the masterbatch, increases the residence time of the masterbatch in the material rolling channel, increases the drying time, prolongs the contact time between the hot air flow and the masterbatch, and ensures the drying effect.

[0058] In this embodiment, the longitudinal shaft 16 is rotatably connected to the inner wall of the mounting cavity 202 through a bearing, and mounting plates fixedly connected to the lifting plate 2 are passed through both ends of the transverse shaft 17. The transverse shaft 17 is rotatably connected to the mounting plate through a bearing, and the second transmission gear group includes a group of bevel gears with a transmission ratio greater than one.

[0059] Specifically, the floating block 13 can move synchronously with the lifting plate 2 without providing a separate power source.

[0060] In this embodiment, a group of disc-shaped partitions 20 are passed through both sides of the lifting plate 2 , the circumferential side walls of the partitions 20 are in sliding contact with the inner wall of the drying cylinder 1 , and the inner wall of the partitions 20 is in contact with the guide plate 7 .

[0061] Specifically, the masterbatch is confined between the partitions 20 to prevent the masterbatch from contacting the transmission components, thereby ensuring the lifting effect.

[0062] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
