A cooling water tank

Abstract

This utility model discloses a cooling water tank, including a base plate. Support rods are fixed at the four corners of the upper surface of the base plate. A cooling tank is fixedly connected to the top of multiple support rods. Multiple partitions are fixed inside the cooling tank, dividing it into multiple cooling chambers. Each cooling chamber contains several staggered second guide wheels. This utility model includes a cooling tank, partitions, cooling chambers, first guide wheels, second guide wheels, a chiller, a water supply pipe, and branch pipes. The partitions divide the cooling tank into multiple cooling chambers, resulting in different water temperatures in each chamber. The cable passes through multiple cooling chambers sequentially for gradual cooling, avoiding a uniform water temperature throughout the cooling tank which would lead to poor cooling. Furthermore, the staggered arrangement of the second guide wheels within each cooling chamber increases the distance the cable travels within the chamber, thereby increasing the cooling time and ensuring effective cooling.

Description

Technical Field

[0001] This utility model relates to the field of cooling water technology for cable production, and in particular to a cooling water tank. Background Technology

[0002] In cable manufacturing, cooling water tanks are crucial equipment after extrusion molding, used to rapidly reduce the temperature of high-temperature cables, allowing them to set and ensuring material performance. Traditional cooling water tanks are mostly straight-line open or closed structures, using a water pump to circulate cooling water for heat exchange. Their working principle is that the cable enters the tank from one end, is cooled, and exits from the other end, with the cooling water typically flowing in either counter-current or co-current patterns. Currently, common tank materials are stainless steel or PVC, and their length is designed according to the cable's cooling requirements. A well-designed cooling water tank structure is of great significance for improving cable production efficiency and reducing energy consumption.

[0003] However, existing cable cooling water tanks have the following drawbacks: To ensure complete cooling of the cables, the tank needs to be designed to be long enough to allow sufficient time for the cables to be cooled by the cold water. This results in excessively long tanks, requiring larger workshops to accommodate them. Secondly, the existing tanks are completely interconnected, leading to a situation where the water temperature is high at the beginning and low at the end during initial cooling. As cooling progresses, the temperature of the entire tank rises, resulting in a decrease in cooling efficiency at the rear. Furthermore, the continuous heating of the cooling water by the high-temperature cables causes water temperature stratification within the tank (hot water rises, cold water sinks), further exacerbating uneven cooling. Therefore, further improvements are needed. To this end, we propose a new type of cooling water tank. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cooling water tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling water tank, including a base plate, with support rods fixed at the four corners of the upper surface of the base plate, and a cooling tank fixedly connected to the top of multiple support rods. Multiple partitions are fixed inside the cooling tank, dividing the interior of the cooling tank into multiple cooling chambers. Each cooling chamber is equipped with several staggered second guide wheels, which are rotatably connected to the inner wall of the cooling chamber. A stirring assembly is installed at the bottom of each cooling chamber. A motor driving each stirring assembly to rotate is fixedly installed on the lower surface of the cooling tank. A chiller for supplying water to each cooling chamber is installed on the upper surface of the base plate.

[0006] Furthermore, the water outlet of the chiller is fixedly connected to a water supply pipe, and multiple branch pipes are fixed in the middle of the water supply pipe, with the other end of each branch pipe connected to the bottom of the cooling chamber.

[0007] Furthermore, a return water pipe is fixed to the top of the side wall of each cooling chamber, and the other end of the return water pipe is connected to the water inlet of the chiller.

[0008] Furthermore, notches are provided on both sides of the top of the cooling tank and on the top of the partition plate, and a first guide wheel is rotatably connected inside the notch.

[0009] Furthermore, the stirring assembly includes a vertical shaft that penetrates the bottom wall of the cooling chamber. The vertical shaft is rotatably connected to the bottom of the cooling chamber via a sealed bearing. A stirring blade is fixed at the top of the vertical shaft, and a driven bevel gear is fixed at the bottom of the vertical shaft. A horizontal shaft is fixed at the output end of the motor. A driving bevel gear is fixed on the surface of the horizontal shaft near each driven bevel gear, and the driving bevel gear meshes with the driven bevel gear.

[0010] Furthermore, a mesh is fixed to the bottom of each cooling chamber, and the mesh is located above the stirring blade.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model includes a cooling tank, a partition, cooling chambers, a first guide wheel, a second guide wheel, a chiller, a water supply pipe, and branch pipes. The partition divides the interior of the cooling tank into multiple cooling chambers, resulting in different water temperatures in each chamber. The cable passes through multiple cooling chambers sequentially for staged cooling, avoiding poor cooling effect caused by a uniform water temperature throughout the cooling tank. Furthermore, several second guide wheels are staggered within each cooling chamber to increase the distance the cable travels within the cooling chamber, thereby increasing the cooling time and ensuring the cooling effect.

[0013] 2. In use, this utility model is equipped with a stirring component and a motor. The motor drives each stirring component to rotate in each cooling chamber, thereby stirring the water in each cooling chamber and making the water temperature in each cooling chamber uniform, avoiding water temperature stratification (hot water rises and cold water sinks), which further aggravates uneven cooling.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a cooling water tank is disclosed, comprising a base plate 1, with support rods 2 fixed at the four corners of the upper surface of the base plate 1. The tops of the multiple support rods 2 are fixedly connected to a cooling tank 3. Multiple partitions 4 are fixed inside the cooling tank 3, dividing the interior of the cooling tank 3 into multiple cooling chambers 5. Each cooling chamber 5 is provided with several staggered second guide wheels 7, which are rotatably connected to the inner wall of the cooling chamber 5. A stirring assembly 9 is installed at the bottom of each cooling chamber 5. A motor 10 for driving the rotation of each stirring assembly 9 is fixedly installed on the lower surface of the cooling tank 3. A chiller 13 for supplying water to each cooling chamber 5 is installed on the upper surface of the base plate 1.

[0022] The outlet of the chiller 13 is fixedly connected to a water supply pipe 14, and multiple branch pipes 15 are fixed in the middle of the water supply pipe 14, with the other end of each branch pipe 15 connected to the bottom of the cooling chamber 5.

[0023] In this embodiment, the chiller 13 is model HCR-10ADB, and its control method and working principle are existing technologies, which will not be described in detail here. After the water is cooled by the chiller 13, it is delivered to each cooling chamber 5 through the water supply pipe 14 and multiple branch pipes 15.

[0024] Each cooling chamber 5 has a return water pipe fixed to the top of its side wall, and the other end of the return water pipe is connected to the water inlet of the chiller 13.

[0025] The water becomes hot after heat exchange inside each cooling chamber 5. The heated water overflows back into the chiller 13 through the return water pipe for recooling, thereby using the chiller 13 to circulate and cool the water, and pumping it into the cooling chamber 5 to cool the cable.

[0026] The top of the cooling tank 3 and the top of the partition plate 4 are provided with notches, and the first guide wheel 6 is rotatably connected inside the notches.

[0027] When the cable passes around the top of the cooling tank 3 and the top of the partition 4, the cable is stuck on the surface of the first guide wheel 6. Whenever the cable passes through a first guide wheel 6 and enters the cooling chamber 5, multiple second guide wheels 7 are used to guide the cable, so that the cable moves in a serpentine manner in the cooling chamber 5, increasing the time the cable stays in the cooling chamber 5, thereby ensuring the cooling effect of the cooling water on the cable.

[0028] The stirring assembly 9 includes a vertical shaft 91 that penetrates the bottom wall of the cooling chamber 5. The vertical shaft 91 is rotatably connected to the bottom of the cooling chamber 5 through a sealed bearing. A stirring blade 92 is fixed at the top of the vertical shaft 91, and a driven bevel gear 93 is fixed at the bottom of the vertical shaft 91. A horizontal shaft 11 is fixed at the output end of the motor 10. A driving bevel gear 12 is fixed on the surface of the horizontal shaft 11 and near each driven bevel gear 93. The driving bevel gear 12 meshes with the driven bevel gear 93.

[0029] In this embodiment, the motor 10 is controlled by a separate switch. After the motor 10 is started, the horizontal shaft 11 at the output end of the motor 10 drives each active bevel gear 12 to rotate. The active bevel gear 12 then drives each driven bevel gear 93 to rotate. The stirring blade 92, which is coaxial with the driven bevel gear 93, stirs the water in the cooling chamber 5, so that the water temperature inside the cooling chamber 5 is uniform.

[0030] Each cooling chamber 5 has a mesh 8 fixed at the bottom, and the mesh 8 is located above the stirring blade 92.

[0031] By setting up a partition 8 to separate the stirring blades 92, it is possible to prevent the stirring blades 92 from hitting the cable during rotation.

[0032] Working principle: The cable extruded from the extruder is... Figure 2 As shown, traction is performed, and then the motor 10 and chiller 13 are started to continuously pump cold water into the cooling chamber 5. The cable passes through multiple cooling chambers 5 in sequence to achieve staged cooling. During this process, the motor 10 continuously drives the stirring component 9 at the bottom of each cooling chamber 5 to rotate. The stirring component 9 stirs the water in the cooling chamber 5 to avoid temperature stratification, thereby ensuring the cooling effect of each cooling chamber 5 on the cable.
