Description

Technical Field

[0001] This utility model relates to the field of pickling solution circulation and proportioning technology, and in particular to a circulation and balancing device for rubber pickling solution. Background Technology

[0002] In current rubber production lines, pickling is required before the rubber is loaded into the drying cart and enters the drying line. The pickling solution flows through the drying cart and drips into the return water tank via holes. The acid concentration of the used pickling solution decreases. Due to cost considerations, this used pickling solution needs to be recycled. Currently, before reusing the recycled pickling solution, operators need to add acid crystals to increase the concentration before it can be reused. This process mainly relies on manual operation, which not only consumes a lot of manpower but also easily makes the work area dirty. Furthermore, since the re-mixing of the pickling solution often depends on the operator's experience, errors in the concentration of the pickling solution are inevitable each time, leading to significant fluctuations in the quality and parameters of the finished rubber product. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a circulating balancing device for rubber pickling solution, which has the advantages of effectively reducing the concentration fluctuation of pickling solution and reducing a lot of manpower and time costs.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A circulating balancing device for rubber pickling solution, comprising:

[0006] A solution preparation assembly, wherein a return water pipe is provided on the solution preparation assembly;

[0007] A stock solution buffer assembly, wherein the stock solution buffer assembly is connected to the solution preparation assembly via a first pipe;

[0008] An acid dissolving component, wherein the acid dissolving component is connected to the original solution buffer component via a second pipe;

[0009] A liquid storage tank, which is connected to the liquid dispensing assembly via a third pipe.

[0010] Compared to existing technologies, this application integrates a solution preparation component, a raw solution buffer component, a raw acid dissolving component, and a storage tank to form an automated pickling solution circulation and proportioning system. This system can automatically extract pickling solution from the return water tank, proportion it to the set concentration, and then supply it to the spraying device, achieving the recycling and precise proportioning of the pickling solution. This design significantly reduces labor costs, avoids concentration errors caused by manual proportioning, and improves the quality and parameter consistency of finished rubber products.

[0011] As a preferred embodiment of this utility model, the liquid preparation component includes:

[0012] The solution preparation tank is equipped with a solution level gauge and a solution concentration detection probe. The solution level gauge is used to detect the liquid level in the solution preparation tank, and the solution concentration detection probe is used to detect the concentration of the solution in the solution preparation tank. One end of the return water pipe is connected to the solution preparation tank.

[0013] By employing the above-described scheme, and through the installation of a liquid level gauge and a liquid concentration detection probe, the liquid level and solution concentration within the mixing tank can be monitored in real time. This ensures the accuracy and stability of the mixing process and prevents mixing failures caused by excessively low liquid levels or substandard concentrations. Simultaneously, it provides accurate data support for subsequent automated control, improving the overall system's operational efficiency and reliability.

[0014] As a preferred embodiment of this utility model, the liquid preparation component includes:

[0015] A liquid mixing and stirring motor is mounted on the liquid mixing tank;

[0016] The liquid mixing stirring shaft and the liquid mixing stirring blades are both disposed inside the liquid mixing tank. One end of the liquid mixing stirring shaft passes through the tank wall of the liquid mixing tank and is connected to the drive shaft of the liquid mixing stirring motor. The liquid mixing stirring blades are disposed at the end of the liquid mixing stirring shaft away from the liquid mixing stirring motor.

[0017] By adopting the above-mentioned solution, the mixing motor, mixing shaft, and mixing blades in the mixing assembly can achieve uniform mixing of the solution in the mixing tank. This not only improves the concentration uniformity of the solution but also ensures that the mixed pickling solution meets the requirements of the spraying device. Simultaneously, the mixing process also helps prevent the accumulation of precipitates in the solution, extending the service life of the equipment.

[0018] As a preferred embodiment of this utility model, the original liquid buffer assembly includes:

[0019] A buffer tank is provided with a buffer level gauge, which is used to detect the liquid level height inside the buffer tank.

[0020] By employing the above-described solution, the liquid level in the buffer tank is monitored in real time using a buffer level gauge, allowing for precise control of the input volume of saturated pickling solution and ensuring stability during the pickling solution circulation and balancing process. When the liquid level is too low, operators are promptly alerted to replenish the saturated pickling solution, preventing equipment shutdown due to insufficient liquid. Conversely, when the liquid level is too high, overflow of the saturated pickling solution is prevented, avoiding waste or contamination. This effectively improves the automation level and operating efficiency of the equipment while reducing human error and risks.

[0021] As a preferred embodiment of this utility model, the original acid dissolving component includes:

[0022] A raw acid tank is provided with a raw acid level gauge, which is used to detect the liquid level height inside the raw acid tank.

[0023] By adopting the above solution, the installation of the raw acid level gauge allows operators to monitor the liquid level in the raw acid tank at any time, which helps to ensure a sufficient supply of raw acid and avoid the interruption of the mixing ratio due to insufficient raw acid. At the same time, by monitoring the liquid level in real time, possible leakage problems can also be detected and resolved in a timely manner, preventing damage to the environment and equipment caused by raw acid leakage, and effectively enhancing the safety and reliability of the equipment.

[0024] As a preferred embodiment of this utility model, the original acid tank is equipped with an original acid concentration detection probe, which is used to detect the concentration of the solution in the original acid tank.

[0025] By adopting the above scheme and setting the raw acid concentration detection probe, the concentration of pickling solution in the raw acid tank can be monitored in real time, ensuring that the concentration of pickling solution in the raw acid tank can be close to or reach the concentration of saturated pickling solution.

[0026] As a preferred embodiment of this utility model, the original acid dissolving component includes:

[0027] A raw acid stirring motor is mounted on the raw acid tank.

[0028] The original acid stirring shaft and the original acid stirring blades are both disposed inside the original acid tank. One end of the original acid stirring shaft passes through the tank wall of the original acid tank and is connected to the drive shaft of the original acid stirring motor. The original acid stirring blades are disposed at the end of the original acid stirring shaft away from the original acid stirring motor.

[0029] By employing the above-described scheme, the stirring shaft and blades are rotated by a stirring motor, which thoroughly mixes the acid crystals and solvent, accelerating the dissolution process and improving dissolution efficiency. Simultaneously, the stirring action prevents solution stratification and precipitation, ensuring the homogeneity and stability of the solution. This contributes to improving the quality and production efficiency of the pickling solution, providing a strong guarantee for the stable operation of the rubber production line.

[0030] As a preferred embodiment of this utility model, a water pump is provided on both the second pipe and the third pipe.

[0031] By employing the above-described method, the water pump can precisely control the flow rate and volume of the liquid within the pipeline, thereby ensuring the stability and continuity of the pickling solution during the circulation and balancing process. By adjusting the pump's operating status, operators can flexibly adjust the circulation speed and mixing ratio of the pickling solution according to actual needs, meeting the requirements of different production batches and processes. This improves the flexibility and adaptability of the equipment, and helps optimize the production process and increase production efficiency.

[0032] As a preferred embodiment of this utility model, valves are provided on the first pipe, the second pipe, and the third pipe.

[0033] By adopting the above scheme, the valve can be conveniently used to control the opening and closing of the pipeline, thereby achieving precise control of the pickling solution circulation and balancing process. In addition, the valve can also serve as a safety device, quickly cutting off the liquid flow in emergencies to prevent the accident from escalating, enhancing the safety and controllability of the equipment, and helping to ensure the smooth operation of the production process.

[0034] As a preferred embodiment of this utility model, the liquid storage tank is provided with a water outlet pipe, which is connected to the liquid storage tank, and a valve is provided on the water outlet pipe.

[0035] The above-described solution allows operators to easily control the output volume and timing of the pickling solution, thereby meeting diverse production needs. By adjusting the valve opening degree, the output volume and speed can be precisely controlled, ensuring the stability and continuity of the pickling solution during output. Furthermore, the valve prevents accidental leakage of pickling solution when not needed, avoiding waste or contamination. This improves the equipment's practicality and flexibility, and helps optimize production processes and increase resource utilization efficiency.

[0036] The aforementioned circulating balancing device for rubber pickling solution has the following beneficial effects: Through the mixing component, the raw solution buffer component, the raw acid dissolving component, the storage tank, and the pumps and valves in the pipeline system, precise circulating balancing of the rubber pickling solution is achieved, effectively improving the stability and controllability of the pickling solution concentration ratio, while also greatly enhancing the automation level of the pickling solution concentration ratio. Secondly, by setting up the raw solution buffer component, the return water pipe, and the mixing component, for certain acid solutions whose concentration is difficult to measure, the concentration measurement step can be avoided during the concentration ratio process, greatly improving the ratio ratio efficiency and quality of the pickling solution concentration ratio.

[0045] Reference Figure 1In one embodiment of this utility model, a circulating balancing device for rubber pickling solution includes a solution mixing component 1, a raw solution buffer component 2, a raw acid dissolving component 3, and a storage tank 4. The solution mixing component 1 is equipped with a return water pipe and a clean water pipe. One end of the return water pipe is connected to the solution mixing component 1, and the other end is connected to an external return water pool. Filtered return water in the return water pool can enter the solution mixing component 1 through the return water pipe. One end of the clean water pipe is connected to the solution mixing component 1, and the other end is connected to an external water supply system. The raw solution buffer component 2 is connected to the solution mixing component 1 through a first pipe. The raw acid dissolving component 3 is connected to the raw solution buffer component 2 through a second pipe 5.

By integrating the dispensing component 1, the raw solution buffer component 2, the raw acid dissolving component 3, and the storage tank 4, an automated pickling solution circulation and proportioning system is formed. This system automatically draws pickling solution from the return water tank, proportions it to the set concentration, and then supplies it to the spraying device, achieving the recycling and precise proportioning of the pickling solution. This design significantly reduces labor costs, avoids concentration errors caused by manual proportioning, and improves the quality and parameter consistency of finished rubber products. The outlet pipe and valves on the storage tank 4 allow operators to easily control the output volume and timing of the pickling solution, thereby meeting different production needs. By adjusting the valve opening degree, the output volume and speed can be precisely controlled, ensuring the stability and continuity of the pickling solution during the output process.

[0046] Reference Figure 1 and Figure 2In one embodiment, the solution mixing assembly 1 includes a solution mixing tank 11, a solution mixing stirring motor 13, a solution mixing stirring shaft, and solution mixing stirring blades. The solution mixing tank 11 is equipped with a solution level gauge 12 and a solution concentration detection probe. The solution level gauge 12 is used to detect the liquid level of the pickling solution in the solution mixing tank 11, and the solution concentration detection probe is used to detect the concentration of the pickling solution in the solution mixing tank 11. One end of the return water pipe is connected to the solution mixing tank 11, and one end of the clean water pipe is connected to the solution mixing tank 11. The solution mixing stirring motor 13 is bolted to the top wall of the solution mixing tank 11. The solution mixing stirring shaft and the solution mixing stirring blades are both located inside the solution mixing tank 11, and one end of the solution mixing stirring shaft passes through the tank wall of the solution mixing tank 11 and is connected to the drive shaft of the solution mixing stirring motor 13 by screws. The solution mixing stirring blades are bolted to the end of the solution mixing shaft away from the solution mixing stirring motor 13. By using the liquid level gauge 12 and the concentration detection probe, the liquid level and concentration in the mixing tank 11 can be monitored in real time, ensuring the accuracy and stability of the mixing process and preventing mixing failures due to low liquid level or insufficient concentration. Simultaneously, it provides accurate data support for subsequent automated control, improving the overall system's operating efficiency and reliability. The mixing stirring motor 13, mixing stirring shaft, and mixing stirring blades in the mixing assembly 1 achieve uniform stirring of the solution in the mixing tank 11, not only improving the concentration uniformity of the solution but also ensuring that the mixed pickling solution meets the requirements of the spraying device. Furthermore, the stirring process helps prevent the accumulation of precipitates in the solution, extending the equipment's service life.

[0047] Reference Figure 2 In one embodiment, the raw material buffer assembly 2 includes a buffer tank 21 located above the dispensing tank 11. A buffer level gauge 22 is installed in the buffer tank 21 to detect the liquid level within it. The buffer tank 21 is connected to the dispensing tank 11 via a first pipe. By monitoring the liquid level in the buffer tank 21 in real time using the buffer level gauge 22, the input volume of the saturated pickling solution can be precisely controlled, ensuring stability during the pickling solution circulation and balancing process. When the liquid level is too low, the operator can be promptly alerted to replenish the saturated pickling solution, preventing equipment shutdown due to insufficient liquid. Conversely, when the liquid level is too high, overflow of the saturated pickling solution can be prevented, avoiding waste or contamination. This effectively improves the automation level and operating efficiency of the equipment while reducing human error and risk.

[0048] Reference Figure 1 and Figure 2In one embodiment, the raw acid dissolution assembly 3 includes a raw acid tank 31, a raw acid stirring motor 33, a raw acid stirring shaft 34, and raw acid stirring blades 35. The raw acid tank 31 is equipped with a raw acid level gauge 32, which is used to detect the liquid level in the raw acid tank 31. The raw acid stirring motor 33 is bolted to the top wall of the raw acid tank 31. The raw acid stirring shaft 34 and the raw acid stirring blades 35 are both located inside the raw acid tank 31. One end of the raw acid stirring shaft 34 passes through the tank wall of the raw acid tank 31 and is connected to the drive shaft of the raw acid stirring motor 33 by screws. The raw acid stirring blades 35 are bolted to the end of the raw acid stirring shaft 34 away from the raw acid stirring motor 33. It is worth noting that during the preparation of the pickling solution, the operator needs to add an excess of acid crystals into the raw acid tank 31 to ensure that the pickling solution in the raw acid tank 31 is saturated. The presence of the raw acid level gauge 32 allows operators to monitor the acid level in the raw acid tank 31 at any time, ensuring a sufficient supply of raw acid and preventing discontinuation of the mixing process due to insufficient acid. Simultaneously, real-time level monitoring allows for the timely detection and resolution of potential leaks, preventing environmental and equipment damage caused by leaks and effectively enhancing equipment safety and reliability. The raw acid stirring motor 33 drives the stirring shaft and blades to rotate, thoroughly mixing acid crystals and solvent, accelerating the acid crystal dissolution process and improving dissolution efficiency. Simultaneously, the stirring action prevents solution stratification and precipitation, ensuring solution homogeneity and stability, which helps improve the quality and production efficiency of the pickling solution, providing strong support for the stable operation of the rubber production line.

[0049] In an optional embodiment, an acid concentration detection probe is installed inside the acid tank 31 to detect the concentration of the solution inside the acid tank 31. By setting up the acid concentration detection probe, the concentration of the pickling solution inside the acid tank 31 can be monitored in real time, ensuring that the concentration of the pickling solution inside the acid tank 31 can approach or reach the concentration of saturated pickling solution.

[0050] Reference Figure 1 and Figure 2 In one embodiment, water pumps 7 are installed on both the second pipe 5 and the third pipe 6. The water pumps 7 can precisely control the flow rate and volume of the liquid within the pipes, thereby ensuring the stability and continuity of the pickling solution during the circulation and balancing process. By adjusting the operating status of the water pumps 7, operators can flexibly adjust the circulation speed and mixing ratio of the pickling solution according to actual needs to meet the requirements of different production batches and processes, improving the flexibility and adaptability of the equipment, and helping to optimize the production process and improve production efficiency.

[0051] In one embodiment, valves are installed on the first pipe, the second pipe 5, and the third pipe 6. In this embodiment, solenoid valves are used as valves. The valves can conveniently control the opening and closing of the pipes, thereby achieving precise control of the pickling solution circulation and balancing process. In addition, the valves can also serve as safety devices, quickly cutting off the liquid flow in emergencies to prevent the accident from escalating, enhancing the safety and controllability of the equipment, and helping to ensure the smooth operation of the production process.

[0052] It is worth noting that the liquid level gauge 12, buffer level gauge 22, and original acid level gauge 32 mentioned in this embodiment are all existing float level gauges. In other embodiments, different types of level gauges in the prior art may be used depending on the actual situation, which will not be elaborated here. The liquid concentration detection probe and original acid concentration detection probe mentioned in this embodiment are optical concentration meters in the prior art. The concentration of the solution can be calculated by measuring the absorption, scattering, or reflection of light by the solution. In other embodiments, acid-base concentration meters in the prior art can also be used to detect the concentration of the solution. A pH probe can also be used to measure the pH value of the solution, thereby indirectly inferring whether the solution concentration is at a suitable level by the pH value of the solution.

[0053] By using the solution preparation component 1, the raw solution buffer component 2, the raw acid dissolving component 3, the storage tank 4, and the water pump 7 and valves in the pipeline system, precise circulation and balancing of the rubber pickling solution are achieved, effectively improving the stability and controllability of the pickling solution concentration ratio, and greatly enhancing the automation level of the pickling solution concentration ratio. Secondly, through the setup of the raw solution buffer component 2, the return water pipe, and the solution preparation component 1, for some acid solutions whose concentration is difficult to measure, the step of measuring the concentration can be avoided during the concentration ratio process. A fixed amount of saturated pickling solution can be directly added to a fixed amount of return water. Then, by observing the pickling effect, the amount of pickling solution added can be adjusted, and finally, a suitable amount of saturated pickling solution can be obtained. This allows setting a fixed amount of saturated pickling solution to be added after each fixed amount of return water is drawn back, thus achieving a pickling solution of suitable concentration, thereby greatly improving the ratio efficiency and quality of the pickling solution concentration ratio.
