Description

Technical Field

[0001] This utility model relates to the technical field of wire drawing machine production equipment, specifically an automatic water replenishment device for cooling water tanks. Background Technology

[0002] Cooling water tanks are widely used in fields with precise operating conditions, such as wire drawing machines and film production. Their core function is to achieve a cooling effect through stable water circulation. Therefore, it is well known in the industry that this equipment has extremely high requirements for the temperature, water level, and water quality stability of the water tank. In order to maintain these key parameters, the traditional operation generally adopts the method of manually replenishing water periodically. The water replenishment rhythm is manually controlled to avoid drastic fluctuations in the water environment inside the tank, thus ensuring the basic conditions for subsequent production processes.

[0003] Existing cooling water tanks are prone to operational errors due to the difficulty in accurately controlling the rhythm and amount of water replenishment manually. This can lead to water overflow or insufficient water replenishment, causing membrane breakage and shutdown, directly interrupting the production process. Furthermore, excessive or insufficient water replenishment can directly disrupt the water temperature balance within the tank, resulting in abnormal water temperatures and affecting the quality of downstream products. Changes in water temperature can also cause a decrease in the transparency of the membrane during the drawing machine's production process, while simultaneously weakening the membrane's elongation and tensile strength, which does not meet production standards. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic water replenishment device for cooling water tanks, so as to solve the problems mentioned in the background art, which are caused by the difficulty in accurately controlling the rhythm and amount of water replenishment by manual replenishment, which is prone to operational errors, leading to water tank overflow or insufficient water replenishment causing membrane breakage and shutdown, directly interrupting the production process. Furthermore, when too much or too little water is replenished, it will directly disrupt the water temperature balance in the tank, causing abnormal water temperature, which in turn affects the quality of downstream products.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic water replenishment device for a cooling water tank, comprising a water tank body, which is the main structure of a film cooling water tank for a wire drawing machine. A wire drawing guide roller and a traction guide roller are rotatably arranged inside the water tank body, and the wire drawing guide roller and the traction guide roller are used together to traction the wire drawing film. A mounting bracket 1 is fitted into one side of the water tank body, and a mounting bracket 2 is fixedly installed on the other side of the water tank body. The end face of the mounting bracket 1 connected to the guide roller is rotatably adapted, and a hot water recovery tank is provided on each side of the mounting bracket 1. The bottom of the hot water recovery tank is connected to the inlet of the filter via a hot water recovery pipe, and the outlet of the filter is connected to the inlet of the cooler via a pipe. The outlet of the cooler is provided with a main water supply pipe, which is connected to a water supply pump. The water supply pump is connected to the tank body via a second water supply pipe. The second mounting bracket is used to install a water level sensor in the inner cavity of the tank body, and the water level sensor is connected to the controller via an electrical signal.

[0006] By adopting the above technical solution, the linkage structure of water level sensor, controller and water replenishment pump replaces manual water replenishment, and the circulation structure ensures stable water temperature and improves product quality.

[0007] Preferably, the bottom end of the water tank body is connected to water supply pipe one and water supply pipe two, and a sealing element is provided at the connection between the water tank body and each pipe.

[0008] By adopting the above technical solution, the structure connecting the bottom of the water tank body to the branch pipe, along with the sealing components, not only achieves uniform water replenishment but also prevents water level abnormalities and equipment corrosion caused by leakage, thus ensuring stable operation.

[0009] Preferably, the two hot water recovery tanks are located above the traction guide roller, and the two hot water recovery tanks are symmetrically arranged with the axis of the traction guide roller as the axis of symmetry.

[0010] With the above technical solution, two hot water recovery tanks are symmetrically arranged above the traction guide rollers to achieve efficient and thorough collection of hot water, improve heat circulation efficiency, and enhance water temperature control.

[0011] Preferably, the hot water recovery tank has an opening on one side, and the openings of the two hot water recovery tanks are arranged opposite each other.

[0012] With the above technical solution, the openings of the hot water recovery tanks are opposite each other, precisely aligning with the guide roller area to receive hot water, reducing blind spots in water collection and ensuring the continuity of water supply in the circulation system.

[0013] Preferably, the filter is an activated carbon filter, and the filter has two layers of filter elements with progressively higher filtration precision.

[0014] By adopting the above technical solution, the filter with activated carbon material and stepped filter element can achieve efficient filtration of impurities, avoid water pollution from affecting product quality, and extend the service life of the equipment.

[0015] Preferably, each of the four water supply pipes is a branch pipe of the main water supply pipe, and each water supply pipe is equipped with a control valve.

[0016] By adopting the above technical solution, the water supply pipe with control valve is integrated into a single unit, forming a multi-point precise water supply system. The flow rate of each branch can be adjusted as needed to adapt to different water level requirements and improve the accuracy of water supply.

[0017] Preferably, the controller is connected to the water supply pump via a cable and controls its start and stop.

[0018] By adopting the above technical solution, the electrical connection structure between the controller and the water supply pump enables automated start and stop of water supply, avoiding delays caused by manual operation and ensuring real-time stability of the water level.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the automatic water replenishment device for the cooling water tank: 1. Two hot water recovery tanks are symmetrically arranged on both sides of the mounting frame, with the axis of the guide roller as the center of symmetry and the openings facing each other. They can efficiently collect the cooling water heated in the water tank body and transport it to the activated carbon filtration equipment through the hot water recovery pipe. After impurities are filtered out by the two-layer stepped precision filter element built into the filter, the water flows into the cooler to cool down. Then, it is returned to the water tank body through the water pump and branch pipe. This circulation structure ensures that the replenished water is always cooled and clean water, avoiding the sudden change in water temperature caused by the direct injection of cold water when manually replenishing water. 2. Mounting frame one adopts a double fixing structure with interlocking installation and mounting frame two adopts a fixed installation, which respectively adapts to the rotation requirements of the guide roller and the installation stability of the water level sensor. The rotational adaptation setting of the guide roller and the mounting frame ensures the structural reliability of the equipment during operation. 3. The seals at the connection points between the water tank body and each branch pipe effectively prevent water leakage from causing abnormal water levels and equipment corrosion. In addition, the automated water replenishment and circulation system effectively reduces the manpower required for manual inspection, water replenishment and water quality monitoring. The stepped filtration design of the filter extends the filter element replacement cycle, improves the stability of the device operation, and reduces operation and maintenance costs and labor intensity.

[0023] Please see Figures 1-6 The present invention provides a technical solution: an automatic water replenishment device for a cooling water tank, comprising a water tank body 1, a wire drawing guide roller 2, a mounting frame 1 3, a hot water recovery tank 4, a traction guide roller 5, a hot water recovery pipe 6, a filter 7, a cooler 8, a main water replenishment pipe 9, a water replenishment pump 10, a first water replenishment pipe 11, a control valve 12, a second water replenishment pipe 13, a second mounting frame 14, a water level sensor 15, and a controller 16; Among them, the water tank body 1 is the main structure of the film cooling water tank of the wire drawing machine. The wire drawing guide roller 2 and the traction guide roller 5 are rotatably arranged inside the water tank body 1, and the wire drawing guide roller 2 and the traction guide roller 5 are used together to traction the wire drawing film. A mounting bracket 1 3 is fitted into one side of the water tank body 1, and a mounting bracket 2 14 is fixedly installed on the other side of the water tank body 1. The end face of the mounting bracket 1 3 connected to the guide roller 5 is rotatably adapted. A hot water recovery tank 4 is provided on each side of the mounting bracket 1 3. The bottom end of the water tank body 1 is connected to the water supply pipe 1 11 and the water supply pipe 2 13. A sealing element is provided at the connection between the water tank body 1 and each pipe. The water supply pipe 1 11 is a branch pipe of the main water supply pipe 9, with a total of 4 pipes. A control valve 12 is provided on each water supply pipe 1 11. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, select a load-bearing and level installation site, fix the water tank body 1 to the ground with expansion bolts, and install the wire drawing guide roller 2 and the traction guide roller 5 into the bearing housing respectively. Figure 2 As shown, the water tank body 1 is then fitted and installed on one side of the water tank body 1 by mounting bracket 113 and fixedly installed on the other side of the water tank body 1 by mounting bracket 214. Hot water recovery tanks 4 are symmetrically installed on both sides of the mounting frame 3, with the openings of the two tanks facing each other and their centers aligned with the axis of the guide roller 5. The lower edge of the opening is above the guide roller to facilitate rapid water collection. Stainless steel corrugated pipes are used as hot water recovery pipes 6, which are connected to the bottom of the hot water recovery tank 4, the water tank body 1, and the water inlet of the filter 7 by clamps. The joints are sealed with PTFE tape. The filter 7, cooler 8, and water pump 10 are connected in series in sequence. Among them, the filter 7 is an activated carbon filter with a built-in stepped filter element, the cooler 8 is a plate heat exchanger, and the main water supply pipe 9 is further laid, as well as four branch water supply pipes 11 and water supply pump 10 set with branch water supply pipe 13. Each branch water supply pipe 11 is equipped with a control valve 12, and rubber sealing rings are added to all pipe connections. Both water supply pipe 11 and water supply pipe 213 are connected to the bottom of the water tank body 1. Install the water level sensor 15 in the preset hole of the mounting bracket 14, ensuring that the probe is immersed in the inner cavity of the water tank body 1, and connect the water level sensor 15, the water supply pump 10, the control valve 12 and the controller 16 through the cable. Two hot water recovery tanks 4 are located above the guide rollers 5 and are symmetrically arranged with the axis of the guide rollers 5 as the axis of symmetry. One side of each hot water recovery tank 4 has an opening, and the openings of the two hot water recovery tanks 4 are opposite each other. The bottom of each hot water recovery tank 4 is connected to the inlet of the filter 7 via a hot water recovery pipe 6. The outlet of the filter 7 is connected to the liquid inlet of the cooler 8 via a pipe. The filter 7 is an activated carbon filter and has two layers of filter elements with progressively higher filtration precision inside. The outlet of the cooler 8 is provided with a main water supply pipe 9, which is connected to a water supply pump 10. The water supply pump 10 is connected to the water tank body 1 via a second water supply pipe 13. A second mounting bracket 14 is used to install a water level sensor 15 inside the water tank body 1. The water level sensor 15 is connected to a controller 16 via an electrical signal. The controller 16 is connected to the water supply pump 10 via a cable and controls its start and stop. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, before use, fill the water tank body 1 with pure water to the normal water level, start the water replenishment pump 10 for a short time to circulate and flush the pipeline impurities, then empty the water tank to complete the cleaning, and then set the upper and lower limits of the water level on the human-machine interface of the controller 16. According to the water tank volume, set the flow rate of the water replenishment pump 10 and the initial opening degree of the control valve 12. When in use, the drawing diaphragm is pulled into the water tank body 1 by the drawing guide roller 2 and then guided out by the traction guide roller 5. During the process, the water in the water tank is heated and flows into the hot water recovery tank 4. It enters the filter 7 through the hot water recovery pipe 6 to filter impurities, and then is temporarily stored after being cooled by the cooler 8. During use, the water level sensor 15 monitors the water level in the tank in real time. When the water level is lower than the lower limit, the controller 16 sends a signal to the water replenishment pump 10 to start, and at the same time adjusts the opening of the control valve 12. Water is replenished to the water tank through the first water replenishment pipe 11 and the second water replenishment pipe 13. When the water level reaches the upper limit, the water replenishment pump 10 stops and the control valve 12 closes, realizing fully automatic water replenishment.

[0024] Working principle: When using the automatic water replenishment device for the cooling water tank, when the drawing diaphragm is cooled by the drawing guide roller 2 and the traction guide roller 5 in the water tank body 1, the heated water in the water tank will be collected through the opening of the hot water recovery tank 4 and transported to the filter 7 through the hot water recovery pipe 6. The two-layer stepped precision filter element inside the filter 7 will filter the impurities in the water. The filtered water enters the cooler 8 for cooling treatment, thus completing the hot water recovery and pretreatment. The water level sensor 15 installed inside the water tank body 1 monitors the water level in the water tank in real time and transmits the water level electrical signal to the controller 16. When the controller 16 determines that the water level is lower than the preset threshold, it will send a start signal to the water replenishment pump 10. At this time, the water replenishment pump 10 will transport the water treated by the cooler 8 through the water replenishment main pipe 9, and then replenish the water tank body 1 by adjusting the flow rate through the control valves 12 on the first water replenishment pipe 11 and the second water replenishment pipe 13. When the water level sensor 15 detects that the water level has reached the preset upper limit, the controller 16 will control the water supply pump 10 to stop working, and at the same time adjust the control valve 12 to close the water supply branch, completing one automatic water supply cycle, which increases the overall practicality.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
