Description

Technical Field

[0001] The utility model belongs to the field of masterbatch production equipment, and in particular relates to a masterbatch quick cooling device. Background Art

[0002] In the production process of masterbatch, the raw materials of molecular wax, plastic particles or plastic powder and color powder or filler are mixed and plasticized by extruder after high-speed stirring to form plastic melt, and masterbatch is extruded by extruder die head. The masterbatch is granulated after cooling. At present, the cooling of the masterbatch after granulation is achieved by water cooling, but water cooling consumes a lot of water, and a water circulation structure is required to reciprocate and cool the cooled water. This equipment not only takes up a lot of space, but also consumes a lot of energy. Therefore, air cooling is also used to cool the masterbatch, but the air cooling form must be able to fully disperse the masterbatch to achieve a better cooling effect for the masterbatch. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a masterbatch fast cooling device, which provides a cooling chamber in a box body, which is divided by a dispersion plate. The feed hole provided on the baffle plate on the feed port is connected to the feeding equipment, and the masterbatch is placed in the upper chamber of the cooling chamber. The masterbatch hits on the retaining ring to achieve dispersion of the masterbatch. Thereafter, the masterbatch enters the cavity on the dispersion plate respectively, and the blower connected to the exhaust port draws air from outside the box to cool the masterbatch. The masterbatch is directly discharged from the discharge port without staying, thereby completing the rapid cooling of the masterbatch.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A masterbatch quick cooling device comprises a box body and a dispersion plate, wherein a cooling chamber is arranged in the box body, the dispersion plate is horizontally placed in the cooling chamber and divides the cooling chamber into an upper chamber and a lower chamber, a plurality of cavities penetrating from top to bottom are arranged on the dispersion plate, a feed port connected to the upper chamber and a discharge port connected to the lower chamber are arranged on the outer side wall of the box body; a baffle is also arranged on the box body, one end of the baffle is rotatably connected to the edge of one end of the feed port, the other end of the baffle is connected to the edge of the other end of the feed port by a buckle, a feed hole and a plurality of lock holes distributed around the feed hole as the center are arranged on the baffle plate, the feed hole is connected to the upper chamber; an air inlet connected to the upper chamber is arranged at the upper end of the box body, an exhaust port connected to the upper chamber is arranged on the outer side wall of the box body, and the exhaust port is located at the lower end of the feed port.

[0006] A retaining ring is also provided in the box body, and a supporting foot is provided on the side wall of the retaining ring, and the supporting foot is detachably connected to the inner wall of the box body, and the feed hole points to the retaining ring; a retaining bar is provided in the retaining ring, and the retaining bars are distributed in a cross shape; a retaining ring is provided on the retaining bar with the cross-shaped retaining bar as the center, and the diameter of the retaining ring is smaller than the diameter of the feed hole.

[0007] The masterbatch quick cooling device adopting this structure has a dispersion plate in the box body that divides the cooling chamber into an upper chamber and a lower chamber. The dispersion plate is provided with a plurality of cavities that penetrate up and down. The upper chamber is an entry space for the masterbatch, and the lower chamber is connected to the discharge port for exporting the masterbatch. A baffle is provided on the feed port, and the baffle can be rotatably connected to the feed port and fixed in the form of a buckle. The feed hole on the baffle is connected to the feed equipment and is flange-connected through a lock hole. The masterbatch entering from the feed hole can be dispersed into each cavity. By dispersing the masterbatch, each masterbatch can dissipate heat in the form of air. It is better to set the dispersion plate to a metal material, so that the heat emitted by the masterbatch can be better cooled.

[0008] Simply allowing the masterbatch to pass through the cavity for air cooling will not have a very good effect, and the masterbatch that enters directly from the feed hole will be largely concentrated in the middle of the dispersion plate, while it is difficult for the masterbatch to pass through the edge of the dispersion plate. As a result, too many masterbatch pass through the middle of the dispersion plate, causing the air temperature of the position itself to rise, and the subsequent masterbatch cannot be cooled well, while few masterbatch can pass through the edge of the dispersion plate with a lower temperature. Therefore, a retaining ring is set in the feeding direction of the feed hole, and the side wall of the retaining ring is connected to the inner wall of the box through a supporting foot. A cross-shaped retaining bar is set in the retaining ring, and a retaining ring is added with the cross of the retaining bar as the center. The diameter of the retaining ring is smaller than the diameter of the feed hole. Therefore, when the masterbatch enters the upper cavity from the feed hole, it will hit the retaining bar and the retaining ring. The blocked masterbatch will be dispersed, with a part entering the dispersion plate from the middle and a part entering the dispersion plate from the periphery, so that the masterbatch can fully enter the cavity on the dispersion plate for cooling.

[0009] However, the effect of cooling the masterbatch by the cavity alone is not the best. Therefore, an exhaust port is set at the lower end of the feed port, and the exhaust port is connected to the blower to extract the air in the upper cavity out of the exhaust port. The upper cavity from which the air is extracted is replenished with air through the air inlet at the upper end of the box and the lower cavity, so as to realize the air flow in the upper cavity. The air sucked into the upper cavity from the bottom to the top will inevitably pass through the cavity. On the one hand, it can absorb the heat on the dispersion plate, and on the other hand, it can dissipate heat and cool the masterbatch passing through.

[0010] Furthermore, a transfer port with a cylindrical structure is embedded and connected to the air exhaust port, a mesh plate is provided at one end of the transfer port, and a flange is provided at the other end of the transfer port, and the flange is abutted against the outer side wall of the box body.

[0011] Compared with the prior art, the utility model has the advantages that: through the setting of the dispersion plate, the masterbatch entering the upper cavity is introduced into the cavity, and the heat is dissipated in the process of the masterbatch passing through the cavity. In order to allow the masterbatch to be dispersed to the peripheral position of the dispersion plate, the retaining ring is set to block it, so that the masterbatch hitting the retaining ring is dispersed, and all the cavities on the dispersion plate are fully utilized to cool the masterbatch, and the blower on the exhaust port is used to realize the air flow in the box. On the one hand, the heat on the dispersion plate can be adsorbed, and on the other hand, the masterbatch passing through can be dissipated and cooled. The masterbatch that has completed cooling falls into the lower cavity for export, thereby realizing rapid cooling of the masterbatch. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A retaining ring 15 is also provided in the box body 1, and a supporting foot is provided on the side wall of the retaining ring 15, and the supporting foot is detachably connected to the inner wall of the box body 1, and the feed hole 141 points to the retaining ring 15; a retaining bar is provided in the retaining ring 15, and the retaining bars are distributed in a cross shape; a retaining ring is provided on the retaining bar with the cross-shaped retaining bar as the center, and the diameter of the retaining ring is smaller than the diameter of the feed hole 141.

[0022] Furthermore, a cylindrical adapter 18 is embedded and connected to the air outlet 17 , a mesh plate 181 is provided at one end of the adapter, and a flange 182 is provided at the other end of the adapter, and the flange 182 abuts against the outer wall of the box body 1 .

[0023] Description of the working method of this utility model:

[0024] The masterbatch quick cooling device adopting the structure is provided with a dispersion plate 2 in the box body 1 to divide the cooling chamber 11 into an upper chamber 111 and a lower chamber 112. The dispersion plate 2 is provided with a plurality of cavities 21 penetrating from top to bottom. The upper chamber 111 is an entry space for the masterbatch, and the lower chamber 112 is connected to the discharge port 13 for exporting the masterbatch. A baffle 14 is provided on the feed port 12. The baffle 14 can be rotatably connected to the feed port 12 and fixed in the form of a buckle. A feed hole 141 on the baffle 14 is connected to a feed device and is flange-connected through a lock hole 142. The masterbatch entering from the feed hole 141 can be dispersed into each cavity 21. By dispersing the masterbatch, each masterbatch can be radiated in the form of air. It is better to set the dispersion plate 2 to a metal material, so that the heat emitted by the masterbatch can be better cooled.

[0025] Simply allowing the masterbatch to pass through the cavity 21 for air cooling will not have a very good effect, and the masterbatch that enters directly from the feed hole 141 will be concentrated in the middle of the dispersion plate 2 to a large extent, while it is difficult for the masterbatch to pass through the edge of the dispersion plate 2. As a result, too many masterbatch pass through the middle of the dispersion plate 2, causing the air temperature of the position itself to rise, and the subsequent masterbatch cannot be well cooled, while few masterbatch pass through the edge of the dispersion plate 2 with a lower temperature. Therefore, in the feeding direction of the feed hole 141, a A retaining ring 15 is provided, and the side wall of the retaining ring 15 is connected to the inner wall of the box body 1 through a supporting foot. A cross-shaped retaining bar is arranged in the retaining ring 15, and a retaining ring is added with the cross of the retaining bar as the center. The diameter of the retaining ring is smaller than the diameter of the feed hole 141. Therefore, when the masterbatch enters the upper cavity 111 from the feed hole 141, it will hit the retaining bar and the retaining ring. The blocked masterbatch will be dispersed, with a part entering the dispersion plate 2 from the middle and a part entering the dispersion plate 2 from the periphery, so that the masterbatch can fully enter the cavity 21 on the dispersion plate 2 for cooling.

[0026] However, the effect of cooling the masterbatch by relying solely on the cavity 21 is still not the best. Therefore, an exhaust port 17 is set at the lower end of the feed port 12, and the exhaust port 17 is connected to the blower to extract the air in the upper cavity 111 out of the exhaust port 17. The upper cavity 111 from which the air is extracted is replenished with air through the air inlet 16 at the upper end of the box body 1 and the lower cavity 112, so that the air flow in the upper cavity 111 is realized. The air sucked into the upper cavity 111 from the bottom to the top will inevitably pass through the cavity 21. On the one hand, it can absorb the heat on the dispersion plate 2, and on the other hand, it can dissipate heat and cool the masterbatch passing through.

[0027] However, since the masterbatch is a granular substance, if there is no obstruction for the exhaust port 17, it is very likely that the masterbatch will enter the exhaust port 17 and affect the operation of the blower. Therefore, an adapter 18 is embedded in the exhaust port 17, and a baffle 14 for blocking the masterbatch is set at one end of the adapter 18, and a flange 182 is set at the other end for connecting to the blower. The adapter 18 is embedded in the exhaust port 17, which can achieve the purpose of extracting air while preventing the masterbatch from entering the blower. Since the adapter 18 is separately nested in the exhaust port 17, an adapter 18 with different mesh sizes of the mesh plate 181 can be selected for installation according to the size of the masterbatch. A larger mesh is used for larger masterbatch, which can have a larger air flow rate.

[0028] The beneficial effect of the utility model is that: through the setting of the dispersion plate 2, the masterbatch entering the upper cavity 111 is introduced into the cavity 21, and the heat is dissipated in the process of the masterbatch passing through the cavity 21. In order to allow the masterbatch to be dispersed to the peripheral position of the dispersion plate 2, the retaining ring 15 is set to block it, so that the masterbatch hitting the retaining ring 15 is dispersed, and all the cavities 21 on the dispersion plate 2 are fully utilized to cool the masterbatch, and the blower on the exhaust port 17 is used to realize the air flow in the box 1. On the one hand, the heat on the dispersion plate 2 can be adsorbed, and on the other hand, the masterbatch passing through can be dissipated and cooled. In addition, the adapter 18 with a mesh plate 181 is nested on the exhaust port 17 to isolate the masterbatch and prevent the masterbatch from falling into the blower. The masterbatch that has completed cooling falls into the lower cavity 112 for export, thereby realizing rapid cooling of the masterbatch.

[0029] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
