Description

Technical Field

[0001] This utility model relates to the technical field of galvanizing production equipment, and in particular to a temperature gradient control device for a galvanizing tank. Background Technology

[0002] In galvanizing production, the uniformity of the zinc bath temperature distribution is crucial to the coating thickness, adhesion, and surface quality of galvanized parts. If the temperature is too low in some areas, it will reduce the fluidity of the zinc bath, causing zinc layer to accumulate on the surface of the galvanized parts, resulting in uneven thickness, protrusions, or runs. If the temperature is too high in some areas, it will accelerate the oxidation of the zinc bath, and the generated zinc oxide impurities will mix into the coating, which will reduce the bonding strength between the coating and the substrate, resulting in poor adhesion and affecting the appearance and corrosion resistance.

[0003] The existing temperature gradient control devices for galvanizing baths still have the following problems:

[0004] 1. Most of the temperature gradient control devices for galvanizing tanks adopt the method of overall heating or single-area temperature control, which cannot achieve differentiated temperature gradient control according to the process requirements of different locations in the galvanizing tank. This is not conducive to meeting their respective temperature requirements, resulting in frequent coating quality problems of galvanized parts, as well as energy waste and increased production costs.

[0005] 2. Most of the cooling devices in the temperature gradient control devices of some galvanizing tanks use a single cooling water pipe for cooling, which affects the accuracy and response speed of the cooling in the discharge temperature control zone. This is not conducive to adapting to the different temperature control needs of different areas in galvanizing production, resulting in the discharge zone temperature easily exceeding the standard or the cooling being delayed, which in turn leads to insufficient recovery of residual zinc from galvanized parts, affected coating quality, and energy waste. Utility Model Content

[0006] The purpose of this utility model is to provide a temperature gradient control device for galvanizing tanks, which solves the problem that most existing temperature gradient control devices for galvanizing tanks adopt overall heating or single-area temperature control, which is not conducive to meeting individual temperature requirements, and most of them use a single cooling water pipe for cooling, which is not conducive to adapting to the differentiated temperature control requirements of different areas in galvanizing production.

[0007] To achieve the above objectives, a temperature gradient control device for a galvanizing tank is provided, comprising a tank body. Two partition plates are fixedly installed inside the tank body, dividing the tank body into three temperature control zones. Installation slots are provided on both sides of the tank body and on both sides of the partition plates. Electric heating tubes are installed in each installation slot. Several temperature sensors are arranged from top to bottom at one end of each of the three temperature control zones inside the tank body. A controller is installed at the front end of the tank body. Installation slots are provided at the other end of each of the three temperature control zones inside the tank body, and condenser tubes are installed in each installation slot.

[0008] According to the aforementioned galvanizing tank temperature gradient control device, a fixing plate is fixedly installed on one side of the tank, two support columns are fixedly installed at the bottom of the fixing plate, and three sets of coolant tanks are fixedly installed on the fixing plate.

[0009] According to the aforementioned galvanizing tank temperature gradient control device, a circulating pump is provided on one side of the coolant tank, and condenser pipes are connected to both ends of the circulating pump.

[0010] According to the aforementioned galvanizing tank temperature gradient control device, an inlet is provided on one side of the upper end of the coolant tank, and a blocking block is provided inside the inlet.

[0011] According to the aforementioned galvanizing tank temperature gradient control device, an opening is provided on the other side of the upper end of the coolant tank, and an installation box is fixedly installed on the upper end of the coolant tank and above the opening.

[0012] According to the aforementioned galvanizing tank temperature gradient control device, an installation plate is fixedly installed in the middle of the installation box, and a motor is fixedly installed at the upper end of the installation plate.

[0013] According to the aforementioned galvanizing bath temperature gradient control device, the output end of the motor is connected to a rotating shaft through a coupling, with fan blades mounted on the rotating shaft.

[0014] According to the aforementioned galvanizing tank temperature gradient control device, the bottom of the tank is provided with three discharge pipes, each of which is equipped with a flow regulating valve.

[0015] The above-mentioned solution has the following beneficial effects:

[0016] 1. This patent, by setting up a partition plate, electric heating tube, temperature sensor, condenser tube and controller, is conducive to achieving differentiated and precise gradient control of the temperature of different temperature control zones in the galvanizing tank during use, meeting the process requirements of each zone and ensuring the coating quality of galvanized parts, avoiding coating quality problems and energy waste caused by the single temperature control, incomplete temperature detection and slow control response of traditional devices.

[0017] 2. By setting up a motor, rotating shaft, fan blades, circulating pump, coolant tank and condenser, this patent facilitates the formation of a highly efficient closed-loop cooling system during use. It quickly cools the discharge temperature control zone and maintains the coolant at a low temperature to ensure cooling stability. This avoids the problems of low cooling efficiency and rapid temperature rise in the discharge zone caused by traditional single cooling methods, which can lead to temperature runaway in the discharge zone and affect the coating quality.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4This utility model discloses a temperature gradient control device for a galvanizing tank, comprising a tank body 1. Two partition plates 4 are fixedly installed inside the tank body 1, dividing it into three temperature control zones. Installation slots 3 are provided on both sides of the tank body 1 and on both sides of the partition plates 4, each containing an electric heating element 5. Several temperature sensors 2 are arranged from top to bottom at one end of each of the three temperature control zones within the tank body 1. A controller 11 is located at the front end of the tank body 1. Installation slots 2 12 are provided at the other end of each of the three temperature control zones within the tank body 1, each containing a condenser tube 13. In use, by setting two partition plates 4 inside the tank body 1, the tank body 1 is clearly divided into three independent temperature control zones, laying a stable physical foundation for achieving differentiated temperature gradient control in different areas, effectively avoiding the limitations of traditional overall temperature control or single-zone temperature control. To address the issue of temperature interference caused by zone temperature control, electric heating tubes 5 are installed in the mounting slots 3 on both sides of the tank 1 and the partition plate 4. This allows the heating components to be more evenly distributed in each temperature control zone, providing precise heat supply to meet the temperature requirements of different zones, thus improving heating efficiency and the flexibility of temperature control. In addition, several temperature sensors 2 are installed from top to bottom at one end of each of the three temperature control zones, which can comprehensively and in real time collect temperature data at different depths in each temperature control zone, providing a reliable basis for the controller 11 to accurately judge the temperature and make adjustments. Meanwhile, the condenser tubes 13 installed in the mounting slot 12 at the other end of each temperature control zone can quickly cool down the corresponding temperature control zone when the temperature is too high, further ensuring the temperature stability of each temperature control zone. Ultimately, this helps to improve the uniformity and stability of the coating quality of galvanized parts, and reduce energy consumption and production costs.

[0028] A fixing plate 10 is fixedly installed on one side of the tank 1. Two support columns 9 are fixedly installed at the bottom of the fixing plate 10. Three sets of coolant tanks 6 are fixedly installed on the fixing plate 10. A circulation pump 15 is installed on one side of each coolant tank 6. Both ends of the circulation pump 15 are connected to condenser pipes 13. An inlet 8 is provided on one side of the upper end of the coolant tank 6. A block 7 is installed inside the inlet 8. An opening 22 is opened on the other side of the upper end of the coolant tank 6. A mounting box 14 is fixedly installed on the upper end of the coolant tank 6 and above the opening 22. A mounting plate 19 is fixedly installed in the middle of the mounting box 14. A motor 18 is fixedly installed on the upper end of the mounting plate 19. The output end of the motor 18 passes through the mounting plate 19 and is connected to a rotating shaft 20 through a coupling. A fan blade 21 is provided on the rotating shaft 20. In use, the three sets of coolant tanks 6 are installed on one side of the tank 1 by means of the fixing plate 10 and the support columns 9, so that the coolant tanks 6 and the tank 1 are kept at a reasonable distance to avoid direct heat transfer affecting the coolant temperature. It can also rely on the support column 9 to stabilize the overall structure and adapt to the workshop environment. The three sets of coolant tanks 6 are connected to the three temperature control zone condenser tubes 13 one by one through the circulation pump 15, so that the cooling system can operate independently and avoid interference. The circulation pump 15 can accelerate the circulation of coolant and improve the cooling efficiency. The liquid inlet 8 and the block 7 at the top of the coolant tank 6 facilitate liquid replenishment and prevent impurities from contaminating, ensuring the cleanliness of the cooling system. The combination of the opening 22 at the top of the coolant tank 6, the mounting box 14 and the internal motor 18, shaft 20 and fan blade 21 can dissipate heat for the coolant through the rotation of the fan blade 21, maintain its low temperature and ensure the cooling effect of the condenser tube 13. The overall design takes into account the cooling performance, ease of operation and structural stability, and provides support for precise temperature gradient control. The bottom of the tank 1 is equipped with three discharge pipes 17, each of which is equipped with a flow regulating valve 16. During use, if it is necessary to clean the impurities in the tank during the production process, the flow regulating valve 16 on the discharge pipe 17 at the bottom of the tank 1 can be opened to discharge the material.

[0029] Working principle: When a galvanizing tank temperature gradient control device is put into use, the operator first sets the target temperature for three temperature control zones through the controller 11. Then, several temperature sensors 2, installed from top to bottom at one end of each of the three temperature control zones, collect the temperature of the zinc liquid in each zone in real time and transmit it to the controller 11. The controller 11 compares the actual temperature with the set temperature. If the temperature of a certain temperature control zone is lower than the set value, it controls the electric heating tubes 5 installed on both sides of the tank body 1 and the partition plate 4 to work and heat until the temperature reaches the target. If the temperature of a certain temperature control zone is higher than the set value, the controller... 11. Start the condenser tube 13 in the mounting slot 2 12 at the other end of the corresponding temperature control zone, and at the same time turn on the circulation pump 15 on the side of the coolant tank 6 on the fixing plate 10. The coolant circulates between the condenser tube 13 and the coolant tank 6 under the action of the circulation pump 15 to cool the temperature control zone. Meanwhile, the motor 18 in the mounting box 14 at the upper end of the coolant tank 6 drives the rotating shaft 20 and the fan blade 21 to rotate, and dissipates heat from the coolant in the coolant tank 6 through the opening 22 to ensure the cooling effect. Throughout the entire process, the controller 11 coordinates and controls all components to achieve precise control of the temperature gradient of the three temperature control zones.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
