Description

Technical Field

[0001] The utility model relates to the technical field of glue production, in particular to a circulating cooling device for glue production. Background Art

[0002] Glue is an intermediate that connects two materials. It mostly appears in the form of water and belongs to the category of fine chemicals. There are many types of glue, which are mainly classified by adhesive, physical form, hardening method and material of the adherend.

[0003] During the production process of some glues (for example, polyvinyl ester water-based adhesives), the chemical reaction that occurs is an exothermic reaction. Therefore, the reactor used can be cooled and heat-exchanged through the internal coil to reduce the temperature during the glue production process.

[0004] The existing reactor cooling is concentrated on the inner wall area of the reactor. As a result, the glue material in contact with the inner wall of the reactor cools down quickly, while the glue material distributed in the middle of the reactor cools down slowly, which leads to uneven cooling of the glue material. Based on this, in order to make the glue material cool more evenly, a circulating cooling device for glue production is provided. Utility Model Content

Mixing and cooling components 2 are distributed inside and outside the reactor body 101. The mixing and cooling components 2 include a stirring unit, a driving unit, an inner cooling unit, and an outer cooling unit.

[0036] The driving unit is used to provide a rotational driving force for the stirring unit, and the stirring of the stirring unit is used to stir and mix the materials inside the kettle body 101;

[0037] The internal cooling unit rotates synchronously with the stirring unit to stir and cool the middle area of the material;

[0038] The external cooling unit is used to cool the inner wall of the kettle body 101, thereby cooling the material in contact with the inner wall of the kettle body 101;

[0039] The stirring unit includes a rotating drum 201, a stirring blade 202, and a scraper 203;

[0040] The rotating drum 201 passes through the center of the top of the kettle body 101 to the inside of the mixing chamber 102 and passes through the bottom of the mixing chamber 102 to the inside of the cooling chamber 103. The rotating drum 201 and the kettle body 101 are in a rotationally connected state.

[0041] A plurality of stirring blades 202 are provided and circumferentially distributed and fixed on the outside of the drum 201 and close to the bottom of the inner wall of the mixing bin 102. The rotation of the drum 201 drives the stirring blades 202 to rotate to achieve the mixing operation of the material;

[0042] The scraper 203 is fixed to the outside of the drum 201, and the upper and lower horizontal parts of the scraper 203 are respectively attached to the top and bottom ends of the inner wall of the mixing chamber 102, and the vertical part of the scraper 203 is attached to the side of the inner wall of the mixing chamber 102.

[0043] The driving unit includes a driven gear 204, a driving motor 205, a driving gear 206, and a protective cover 207;

[0044] The driven gear 204 is fixed to the outside of the drum 201 near the top, the driving motor 205 is fixedly installed on the top of the kettle body 101, and the driving gear 206 is fixed to the conveying end of the driving motor 205 and meshes with the driven gear 204. The driving motor 205 drives the drum 201 through the driving gear 206 and the driven gear 204.

[0045] The protective cover 207 is fixed to the top of the kettle body 101 and covers the area where the driven gear 204, the driving motor 205, and the driving gear 206 are located. The top of the rotating drum 201 passes through the top of the protective cover 207. The protective cover 207 is used to protect the transmission area of the driven gear 204, the driving motor 205, and the driving gear 206;

[0046] The inner cooling unit includes a trapezoidal cooling stirring rod 208 and a diverter guide 209;

[0047] There are multiple trapezoidal cooling and stirring rods 208, which are circumferentially distributed and fixed on the outside of the drum 201, and are located in the middle area between the stirring blade 202 and the upper end of the scraper 203.

[0048] The rotating drum 201 and the trapezoidal cooling and stirring rods 208 are hollow structures, and the upper and lower ends of the trapezoidal cooling and stirring rods 208 are in communication with the inner cavity of the rotating drum 201. The diverter guides 209 are welded and fixed to the inner cavity of the rotating drum 201 and are respectively located below the upper end ports of each trapezoidal cooling and stirring rod 208.

[0049] When the water flowing into the inner cavity of the drum 201 contacts the diversion guide 209, it is diverted and enters the trapezoidal cooling and stirring rod 208. The rotating trapezoidal cooling and stirring rod 208 is used to stir the material. The water flow inside the trapezoidal cooling and stirring rod 208 of the drum 201 is used to exchange heat with the material.

[0050] The external cooling unit includes a spiral blade 210, a water inlet pipe 211, and a water outlet pipe 212;

[0051] The spiral blades 210 are distributed inside the cooling chamber 103, and the spiral blades 210 are welded and fixed to the inner and outer ring sides of the cooling chamber 103;

[0052] The water inlet pipe 211 is fixed to the side of the outer wall of the kettle body 101 near the top, and the water inlet pipe 211 passes through the kettle body 101 and is connected to the top of the inner side of the cooling chamber 103;

[0053] The water outlet pipe 212 is fixed to the middle of the bottom of the kettle body 101 and passes through the kettle body 101 to communicate with the inner bottom of the cooling chamber 103 .

[0054] In this embodiment, it should be noted that when the kettle body 101 is used daily, a corresponding bracket is provided at its bottom to keep the water outlet pipe 212 and the discharge port 105 off the ground. The top of the drum 201 is connected to the cooling water tank via a rotating connector, an external water pipe, and a water pump. The water inlet pipe 211 is directly connected to the cooling water tank via the external water pipe and the water pump. The water outlet pipe 212 is connected to the cooling water return pipe via an external pipe.

[0055] When the glue raw material is added to the mixing bin 102 through the feed port 104, the drive motor 205 is started synchronously, and the drive motor 205 drives the driving gear 206 to rotate, and the driving gear 206 drives the driven gear 204 and the rotating drum 201 to rotate, and the rotating drum 201 drives the stirring blade 202, the scraper 203, and the trapezoidal cooling stirring rod 208 to rotate synchronously. The rotating stirring blade 202 and the trapezoidal cooling stirring rod 208 are used to stir the materials, and the scraper 203 can scrape the inner wall of the mixing bin 102 to prevent the materials from adhering to the inner wall.

[0056] When the material needs to be cooled, the water pump can be started to transport cooling water to the drum 201 and the water inlet pipe 211. The water flowing into the drum 201 contacts the diversion guide 209 during its downward flow and is then diverted into the trapezoidal cooling stirring rod 208. It then re-converges into the drum 201 through the bottom port of the trapezoidal cooling stirring rod 208 and flows into the bottom of the cooling bin 103 through the bottom port of the drum 201. During this process, the water flow inside the drum 201 and the trapezoidal cooling stirring rod 208 undergoes heat exchange reaction with the material, so that the material in the middle is efficiently cooled.

[0057] The water flow inside the water inlet pipe 211 will enter the top of the cooling bin 103 and flow downward along the trajectory of the spiral blade 210 to the bottom of the cooling bin 103. During this process, the water flow inside the cooling bin 103 can cool the materials in contact with the inner side of the mixing bin 102.

[0058] The water flow gathered at the bottom of the cooling bin 103 cools the material in contact with the bottom of the mixing bin 102, and the cooling water is finally discharged through the outlet pipe 212. Through the cooperation of the above multiple parts, the material can be evenly cooled, and the overall cooling efficiency is faster.

[0059] Please refer to Figures 3-5 The distances between the vertical portions of the multiple trapezoidal cooling and stirring rods 208 and the rotating drum 201 increase successively, and the upper and lower lateral portions of the multiple trapezoidal cooling and stirring rods 208 are staggered along the vertical direction.

[0060] In this embodiment, the trapezoidal cooling stirring rods 208 of different sizes can have different rotational trajectories, thereby causing the material positions they contact to be different, which not only enables better stirring and mixing, but also makes the cooling of the material more uniform.

[0061] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
