Description

Technical Field

[0001] This utility model relates to the field of water-based coating processing technology, and in particular to a water chiller for rapid cooling in water-based coating production. Background Technology

[0002] Water-based coatings refer to coatings that use water as a solvent or dispersion medium. Based on the type of binder used, water-based coatings are divided into two main categories: natural water-based coatings made from natural substances or minerals, and petrochemical water-based coatings made from synthetic resins. During the production of water-based coatings, a chiller is needed to provide a stable low-temperature environment to prevent deterioration or hardening during storage, ensuring consistent coating quality.

[0003] However, existing chillers mainly cool the paint storage tank by using a water bath. This results in the paint near the inner wall of the tank cooling faster, while the paint in the center of the tank cools slower, leading to uneven cooling and a slow cooling rate.

[0004] To address this issue, we propose a rapid cooling chiller for water-based coating production. Utility Model Content

[0005] The purpose of this invention is to provide a water chiller for rapid cooling in the production of water-based coatings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chiller for rapid cooling in water-based coating production includes a chilled water cylinder and a coating cylinder. The coating cylinder is placed inside the chilled water cylinder, and coolant is stored in the cavity between the chilled water cylinder and the coating cylinder. A cooling block is installed at the bottom of the chilled water cylinder. A cylinder is provided on the outside of the chilled water cylinder, and a support is installed at the top of the cylinder. A horizontal bar is rotatably connected to the support. An agitator is rotatably connected to the lower end of the horizontal bar away from the support. A motor for driving the agitator to rotate is installed on the horizontal bar. The agitator includes a U-shaped tube. One end of the U-shaped tube is connected to a bend, and the top end of the bend is rotatably connected to the horizontal bar. The other end of the U-shaped tube is connected to a horizontal pipe, and the far end of the horizontal pipe extends into the cavity between the chilled water cylinder and the coating cylinder. One end of the bend extending out of the upper surface of the horizontal bar is connected to a rigid pipe through a rotary joint. The rigid pipe is connected to a water pump through a telescopic pipe. The water pump is connected to the inside of the chilled water cylinder through a second rigid pipe.

[0008] In a further embodiment, the end of the horizontal tube away from the U-shaped tube is connected to an inclined tube, which is inclined toward the inner wall of the cold water cylinder, and the outlet of the inclined tube is lower than the upper port of the paint cylinder.

[0009] In a further embodiment, several straight pipes are symmetrically connected to both sides of the U-shaped tube, and the straight pipes are connected to the interior of the U-shaped tube.

[0010] In a further embodiment, a cooling plate is installed at the bottom of the cold water cylinder. The lower surface of the cooling plate protrudes from the cold water cylinder and is in close contact with the cooling block. The cooling plate is connected to a cooling platform by several cooling columns, and the bottom of the coating cylinder is in close contact with the cooling platform.

[0011] In a further embodiment, a heat sink is mounted on the lower surface of the cooling block, and a cooling fan is mounted on the side of the heat sink.

[0012] In a further embodiment, a second motor is installed below the rotatable connection between the support platform and the crossbar.

[0013] In a further embodiment, the output end of the motor is connected to a bevel gear, which is engaged with a bevel gear ring, and the bevel gear ring is coaxially fixed to the outer side wall of the top end of the bend.

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

[0015] This invention, by incorporating a stirring component, not only stirs the paint inside the paint cylinder to ensure uniform temperature distribution, but also circulates coolant inside the stirring component through a rotary joint, rigid pipe one, telescopic pipe, rigid pipe two, and a water pump, allowing for simultaneous stirring and cooling. The entire device achieves simultaneous cooling from both the inside and outside of the paint cylinder, effectively improving the cooling rate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 A water chiller for rapid cooling in water-based paint production includes a water chiller 1 and a paint cylinder 2. The paint cylinder 2 is used to hold and store paint, and is placed inside the water chiller 1. Coolant is stored in the cavity between the water chiller 1 and the paint cylinder 2. A cooling block 3 is installed at the bottom of the water chiller 1. Specifically, the cooling block 3 is preferably a semiconductor cooling chip, with its cooling end installed close to the water chiller 1 to promote the cooling of the coolant in the water chiller 1. A cylinder 4 is provided on the outside of the water chiller 1, and the cylinder 4 is arranged vertically. Parallel to the axis of the cold water cylinder 1, the top of the cylinder 4 is equipped with a support platform 5, and a crossbar 6 is rotatably connected to the support platform 5. The crossbar 6 is perpendicular to the axis of the cold water cylinder 1. A stirring element 7 is rotatably connected to the lower end of the crossbar 6 away from the support platform 5, and a motor 8 for driving the stirring element 7 to rotate is installed on the crossbar 6, so that the stirring element 7 can rotate inside the paint cylinder 2, promoting uniform temperature distribution of the paint. The cylinder 4 is used to drive the crossbar 6 and the stirring element 7 to rise and detach from the paint cylinder 2 or to descend and extend into the paint cylinder 2 to work.

[0025] Please see Figure 1-3 The mixing component 7 includes a U-shaped tube 71, one end of which is connected to a bent tube 72, and the top end of the bent tube 72 is rotatably connected to the horizontal bar 6. The other end of the U-shaped tube 71 is connected to a horizontal tube 73, and the distal end of the horizontal tube 73 extends into the cavity between the cold water cylinder 1 and the paint cylinder 2. The bent tube 72, the U-shaped tube 71, and the horizontal tube 73 are all hollow inside and connected in sequence. A rotary joint 9 is installed at the end of the bent tube 72 that extends out of the upper surface of the horizontal bar 6. A rigid tube 10 is connected to the outside of the rotary joint 9. The rigid tube 10 is parallel to the horizontal bar 6 and fixed to the horizontal bar 6. The end of the rigid tube 10 away from the rotary joint 9 extends out below the horizontal bar 6 and is connected to a telescopic tube 11. Specifically, the telescopic tube 11 is vertically arranged... The telescopic tube 11 is a telescopic and flexible corrugated tube, which can be extended and retracted according to the length when the cylinder 4 is raised and lowered. At the same time, it can bend and twist according to the angle when the horizontal bar 6 is rotated. The lower end of the telescopic tube 11 is connected to the water pump 13, and the water pump 13 is fixedly connected to the bottom of the cold water cylinder 1. The water pump 13 is connected to the inside of the cold water cylinder 1 through the rigid pipe 2 12. The water supply pipeline is formed by the rotary joint 9, the rigid pipe 10, the telescopic tube 11, the rigid pipe 2 12 and the water pump 13, so as to deliver the coolant to the agitator 7. The coolant in the agitator 7 can finally flow out from the horizontal pipe 73 and return to the cavity between the cold water cylinder 1 and the paint cylinder 2, so that the agitator 7 can cool the paint while stirring it.

[0026] For further details, please refer to Figure 3 The horizontal tube 73 is connected to an inclined tube 74 at the end away from the U-shaped tube 71. The inclined tube 74 is inclined towards the inner wall of the cold water cylinder 1, and the outlet of the inclined tube 74 is lower than the upper port of the paint cylinder 2. This allows the coolant flowing out of the inclined tube 74 to flow back along the inner wall of the cold water cylinder 1, which not only reduces the problem of coolant splashing, but also increases its flow area and promotes the heat dissipation and cooling of the coolant itself. Several straight tubes 75 are symmetrically connected to both sides of the U-shaped tube 71, and the straight tubes 75 are connected to the inside of the U-shaped tube 71, which can increase the heat exchange contact area with the paint and further improve the cooling efficiency.

[0027] Please see Figure 3 A cooling plate 14 is installed at the bottom of the inner part of the cooling water cylinder 1. The lower surface of the cooling plate 14 protrudes from the outside of the cooling water cylinder 1 and is in close contact with the cooling surface of the cooling block 3, so that it is cooled quickly. The cooling plate 14 is connected to the cooling platform 16 through several cooling columns 15. The bottom of the coating cylinder 2 is in close contact with the cooling platform 16. The cooling plate 14, cooling columns 15 and cooling platform 16 are made of metal, and their cooling rate is faster than that of the coolant. They can support the coating cylinder 2 and can also directly contact the outer wall of the coating cylinder 2 for heat exchange, thereby improving the cooling rate.

[0028] Please see Figure 2In order to facilitate rapid heat dissipation of the heat dissipation end of the cooling block 3, a heat sink 17 is installed on the lower surface of the cooling block 3. Specifically, thermal grease is filled between the heat sink 17 and the heating surface of the cooling block 3, and a cooling fan 18 is installed on the side of the heat sink 17 to accelerate the air circulation around the heat sink 17 and promote heat dissipation.

[0029] Please see Figure 2 To facilitate the electric rotation of the horizontal bar 6 relative to the support platform 5, a second motor 19 is installed below the rotational connection between the support platform 5 and the horizontal bar 6. The main body of the second motor 19 is fixedly installed on the lower surface of the support platform 5, and the output end of the second motor 19 is coaxially connected to the rotation shaft of the support platform 5 and the horizontal bar 6, thereby driving the horizontal bar 6 to rotate relative to the support platform 5. When the horizontal bar 6 drives the stirring component 7 to rotate away from the top of the cold water cylinder 1, the paint cylinder 2 can be easily removed from the cold water cylinder 1.

[0030] Please see Figure 4 Considering that the stirring component 7 is in a rotating state, in order to facilitate its operation while transmitting coolant normally, the main body of the motor 8 is fixedly installed with the crossbar 6. The output end of the motor 8 is connected to a bevel gear 20, which is mounted on the crossbar 6 through a bearing seat. The lower edge of the bevel gear 20 is meshed with a bevel gear ring 21, and the bevel gear ring 21 is coaxially fixed on the outer side wall of the top of the bend 72, which can drive the bend 72 to rotate without affecting the connection between the bend 72 and the rotary joint 9.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
