Description

Technical Field

[0001] This utility model relates to the field of industrial coating technology, specifically a coating liquid circulation supply device. Background Technology

[0002] In modern industrial production, continuous annealing (line annealing) is a crucial step in the surface treatment of metal materials and is widely used in fields such as electrical steel, stainless steel, and automotive sheet metal. The precise supply of the coating liquid and the coating quality directly determine the insulation, corrosion resistance, and functional properties of the metal material.

[0003] Currently, existing coating liquid supply systems mostly rely on manual operation and segmented control. For example, during the supply process, intermittent supply or manual start-stop of pump equipment cannot guarantee the continuous and stable delivery of coating liquid to the coating roller surface. Supply interruptions or over-supply often occur, affecting the uniformity of coating on the roller. At the same time, the monitoring methods of traditional systems are limited, and only basic parameters such as liquid level and temperature can be manually inspected at regular intervals. They cannot monitor key process indicators such as viscosity, flow rate, and particle size in real time. Taking viscosity control as an example, when the viscosity of the coating liquid changes due to solvent evaporation or component precipitation, the traditional system cannot respond and adjust in time, ultimately causing quality problems such as uneven coating thickness and surface defects, affecting the manufacturer's use. To address this, we propose a coating liquid circulation supply device. Utility Model Content

[0026] Example 1

[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution: a coating liquid circulation supply device, comprising:

[0028] The base plate 1 and the circulation tank 102 are installed on the top left end of the base plate 1. A liquid level sensor 401 is fixedly installed on the top of the circulation tank 102. A temperature sensor 402 is fixedly installed on the upper end of the inner wall of the circulation tank 102. A diluent delivery pipe 112 is connected to the upper end of the left side of the circulation tank 102. An electric control valve 113 is provided at one end of the diluent delivery pipe 112.

[0029] The transfer pump 101 is fixedly installed on the right end of the top of the base plate 1. A guide pipe 111 is provided between the liquid inlet end of the transfer pump 101 and the lower end of the right side of the circulation tank 102. A flow control valve 406 and a viscosity sensor 407 are provided in the middle end of the guide pipe 111. A delivery pipe 108 is provided at the output end of the transfer pump 101.

[0030] Control panel 103 is fixedly installed on the top left end of base plate 1;

[0031] A support frame 105 is fixedly installed at the middle of the top of the base plate 1. A filter box 106 is fixedly installed at the upper end of one side of the support frame 105. A filter screen plate 104 is fixedly installed at the middle of the inner cavity of the filter box 106. A return pipe 107 is connected between the lower left end of the filter box 106 and the top of the circulation tank 102. A rearward-extending circulation receiving pipe 109 is connected to the right end of the top of the filter box 106.

[0032] A power switch 3 is fixedly installed on the left side of the control panel 103, and a cleaning port 110 is provided on the top of the filter box 106, with a sealing cover at the upper end of the cleaning port 110.

[0033] This technical solution: Before use, first connect the pipes connecting the feeding end and discharge end of the coating roller to the liquid delivery pipe 108 and the circulation receiving pipe 109 respectively. Then, connect the external diluent pipe to the diluent delivery pipe 112. Then check the equipment for any abnormalities. When everything is normal, use mains power. Then, after powering on the device by the power switch 3, the delivery pump 101 can deliver the coating liquid in the circulation tank 102 to the feeding end of the coating roller through the liquid delivery pipe 108 via the guide pipe 111. The setting of the flow control valve 406 and the viscosity sensor 407 can ensure accurate delivery of coating liquid while making the coating liquid flow stably, and can perform real-time viscosity detection of the flowing coating liquid. The flow control valve 406 and the viscosity sensor 407 can synchronously transmit the flow control data and the viscosity detection data of the coating liquid to the control panel 103. At the discharge end of the coating roller, the excess coating liquid is delivered to the circulation receiving pipe 109. After the filter box 106, and with the assistance of the filter screen 104, the returned coating liquid can be filtered. Then, the filtered coating liquid can be sent back to the circulation tank 102 through the return pipe 107, thereby realizing the circulation supply of coating liquid. With the cooperation of the liquid level sensor 401 and the temperature sensor 402, the temperature of the coating liquid in the circulation tank 102 and the liquid level of the remaining coating liquid in the circulation tank 102 can be detected in real time. At the same time, the detected data can be transmitted to the control panel 103. After the control panel 103 processes the transmitted data, if the viscosity of the coating liquid is high, the control panel 103 will open the electric control valve 113 on the diluent delivery pipe 112, so that the diluent in the external diluent pipe can enter the circulation tank 102 and mix with the original coating liquid to dilute it. This can ensure the viscosity of the coating liquid and ensure the uniformity of coating, avoiding the problem of the coating liquid supply system relying too much on manual operation and segmented control.

[0034] It should be noted that the control panel 103, transfer pump 101, liquid level sensor 401, temperature sensor 402, power switch 3 and solenoid valve 113 used in this device can all be purchased directly from the market. At the same time, the connection method and electrical connection relationship of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.

[0035] Example 2

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, an electric heating plate 403 is embedded in the lower end of the inner wall of the circulation tank 102.

[0037] This technical solution: By setting up the electric heating plate 403, the coating liquid can be heated. With the assistance of the temperature sensor 402, the control panel 103 turns the electric heating plate 403 on or off according to the detection data of the temperature sensor 402, so that the temperature of the coating liquid is always kept at a constant standard, ensuring the coating liquid's performance.

[0038] Example 3

[0039] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a drive motor 4 is fixedly installed at the middle of the top of the circulation tank 102, and a stirring shaft 404 is fixedly connected to the output end of the drive motor 4. A stirring impeller 405 is fixedly connected to the outer surface of the stirring shaft 404.

[0040] This technical solution: When the drive motor 4 is turned on by the control panel 103 to drive the stirring shaft 404 and the stirring impeller 405 to rotate, the coating liquid in the circulation tank 102 can be fully stirred, thereby avoiding the occurrence of sedimentation.

[0041] Example 4

[0042] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a liquid mixing tank 2 is provided at the top left end of the base plate 1 and behind the circulation tank 102. A liquid mixing pipe 201 is connected between the upper end of one side of the liquid mixing tank 2 and the top of the circulation tank 102. A control valve 202 is provided at one end of the liquid mixing pipe 201.

[0043] This technical solution: By setting up the liquid preparation tank 2, when the liquid level sensor 401 detects that the coating liquid in the circulation tank 102 is at a preset low level, it sends data feedback to the control panel 103. Then, the control panel 103 opens the control valve 202 on the liquid preparation pipe 201, so that the coating liquid prepared in the liquid preparation tank 2 can enter the circulation tank 102 to replenish it. When the liquid level sensor 401 detects that the coating liquid in the circulation tank 102 is at a preset high level, it sends data feedback to the control panel 103. Then, the control panel 103 closes the control valve 202 on the liquid preparation pipe 201 to complete the replenishment of the coating liquid.

[0044] It should be noted that the liquid preparation tank 2 used in this device can be purchased directly from the market, and the connection method and electrical connection relationship of its components adopt mature conventional methods in the existing technology, so it will not be described in detail here.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
