Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and more specifically, to a liquid supply device and a spraying equipment having the same. Background Technology

[0002] In modern industrial production and laboratory operations, liquid supply systems are crucial for maintaining the stability of continuous processes. Traditional liquid supply systems typically employ a single storage tank, with a level sensor detecting the liquid level within the tank. When the liquid level drops to a preset lower limit, the control system initiates replenishment to maintain the liquid level within the normal range. While this mechanism theoretically manages the storage and supply of antistatic agents effectively, in practical applications, the sensitivity and reliability of the level sensor become key factors affecting system stability.

[0003] Specifically, level sensors may become insensitive due to various reasons (such as sensor aging, dirt accumulation, electronic malfunctions, etc.), resulting in an inability to accurately detect the lower limit of the liquid level, thus affecting the timeliness of liquid replenishment. In some cases, delays or malfunctions of the level sensor may lead to excessively low liquid levels or even drying out of the supply tank, severely impacting the continuity of the production process and the safe operation of the equipment. Furthermore, relying on level sensors for liquid replenishment control means that when the sensor malfunctions, the system will lose its ability to automatically replenish liquid, increasing maintenance costs and operational risks.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] In modern industrial production and laboratory operations, liquid supply systems are crucial for maintaining the stability of continuous processes. Traditional liquid supply systems typically employ a single storage tank, with a level sensor detecting the liquid level within the tank. When the liquid level drops to a preset lower limit, the control system initiates replenishment to maintain the liquid level within the normal range. While this mechanism theoretically manages the storage and supply of antistatic agents effectively, in practical applications, the sensitivity and reliability of the level sensor become key factors affecting system stability.

[0043] Specifically, level sensors may become insensitive due to various reasons such as sensor aging, dirt accumulation, and electronic malfunctions, resulting in an inability to accurately detect the lower limit of the liquid level and thus affecting the timeliness of liquid replenishment. In some cases, delays or malfunctions of the level sensor may lead to excessively low liquid levels or even drying out of the supply tank, severely impacting the continuity of the production process and the safe operation of the equipment. Furthermore, relying on level sensors for liquid replenishment control means that when the sensor malfunctions, the system will lose its ability to automatically replenish liquid, increasing maintenance costs and operational risks.

[0044] The main objective of this invention is to provide a liquid supply device and a spraying equipment having the same, so as to solve the problem of liquid supply interruption caused by the liquid level sensor failing to function properly in the prior art.

[0045] First, this application provides a liquid supply device, which includes a liquid supply tank 1 and a liquid supply pipe 2 connected to the liquid supply tank 1.

[0046] Pump body 3 is mounted on liquid supply tank 1 and connected to liquid supply pipeline 2;

[0047] Storage tank 4 contains antistatic agent. Storage tank 4 is connected to the outlet end of supply pipe 2 so that the antistatic agent is continuously delivered to supply tank 1 through supply pipe 2 under the driving action of pump body 3.

[0048] The spraying component 400 is located at the bottom of the liquid supply tank 1 and is connected to the liquid supply tank 1 so as to continuously spray antistatic agent through the spraying component 400 for spraying operation.

[0049] Specifically, in this embodiment, the liquid supply device provided by this application includes a liquid supply tank 1, such as... Figures 1 to 4 As shown, an antistatic agent is stored in the supply tank 1, and a supply pipe 2 is connected to the supply tank 1. A pump body 3 is installed on one side wall of the supply tank 1 and connected to the supply pipe 2. The supply device also includes a storage tank 4, which is connected to the outlet end of the supply pipe 2. The storage tank 4 stores the antistatic agent. When the pump body 3 is working, it can continuously deliver the antistatic agent in the storage tank 4 to the supply tank 1. A spraying component 400 is installed at the bottom of the supply tank 1. Figure 4As shown, the spraying component 400 in this embodiment can be a spraying nozzle. In use, the pipe can be connected to the spraying nozzle to spray the antistatic agent through the spraying component 400 for spraying operations.

[0050] By connecting the pump body 3 to the liquid supply pipeline 2, the liquid supply device of this application can efficiently and continuously replenish the antistatic agent in the storage tank 4 to the liquid supply tank 1, ensuring that the liquid supply tank 1 always maintains a sufficient liquid level during use, thereby avoiding liquid supply interruption caused by insufficient liquid level and improving the stability and continuity of the liquid supply process.

[0051] The dual-tank structure of supply tank 1 and storage tank 4 enables effective liquid level regulation and replenishment cycles. Storage tank 4 not only stores backup liquid but also assists in liquid level control of supply tank 1, ensuring the reliability of liquid supply. Even in the event of a malfunction of the liquid level sensor in supply tank 1, liquid can be automatically replenished through the preset working cycle of pump 3.

[0052] The spraying component 400, such as the spray nozzle, located at the bottom of the liquid supply tank 1 provides a direct and convenient channel for spraying the antistatic agent. This design enables operators to complete the spraying operation quickly and accurately, improving work efficiency while reducing operational complexity and ensuring the accuracy and safety of the spraying operation.

[0053] The liquid supply device in this application integrates key components such as the liquid supply tank 1, pump body 3, liquid storage tank 4, liquid supply pipeline 2, and spraying component 400 to form a compact and efficient working system. This not only reduces the equipment footprint and facilitates equipment installation and maintenance, but also simplifies the operation process, reduces the learning cost for operators, and improves the overall user experience.

[0054] In summary, the liquid supply device of this application, through its innovative dual-tank circulating liquid replenishment system and convenient spray component design, effectively improves the stability and continuity of the liquid supply process. Simultaneously, it significantly enhances equipment integration and operational convenience, providing strong support for the efficient and safe application of antistatic agents. This demonstrates significant technological advancement and practical application value. In industrial production and laboratory operations, the introduction of this device can significantly reduce production interruptions caused by unstable liquid supply, lower maintenance costs, and improve production efficiency and safety.

[0055] Furthermore, the bottom surface of the liquid supply tank 1 forms a first horizontal surface;

[0056] The liquid supply device also includes a first port 201 disposed on the side wall of the liquid supply tank 1, and the distance between the first port 201 and the first horizontal plane along the first direction is a set distance.

[0057] The storage tank 4 is also provided with a second port 101, which is connected to the first port 201 so that when the antistatic agent in the supply tank 1 exceeds a set distance, the antistatic agent is transported from the first port 201 to the storage tank 4.

[0058] Specifically, the plane at the bottom of the liquid supply tank 1 is a first horizontal plane. The liquid supply device also includes at least two first ports 201 disposed on the side wall of the liquid supply tank 1. The distance between each first port 201 and the first horizontal plane along a first direction is a predetermined distance, wherein the first direction is... Figure 1 From top to bottom, at least two second ports 101 are provided on the liquid storage tank 4. Each second port 101 is connected to one of the first ports 201. When the level of the antistatic agent in the supply tank 1 is higher than a set distance, that is, when the level of the antistatic agent in the supply tank 1 is higher than two first ports 201, the antistatic agent in the supply tank 1 will flow back to the liquid storage tank 4 from the two first ports 201 and the two second ports 101 connected to them. In this way, the level of the antistatic agent in the supply tank 1 can always be kept at the set distance, and the antistatic agent output by the self-spraying liquid component 400 can be continuously output.

[0059] By setting a "set distance" between the bottom of the supply tank 1 and the first port 201, the supply device of this application can achieve precise control of the antistatic agent liquid level. When the liquid level exceeds the set distance, the liquid will automatically flow back from the first port 201 to the storage tank 4, ensuring that the liquid level in the supply tank 1 is maintained at an ideal state, avoiding the problem of unstable liquid supply caused by excessively high or low liquid levels, and improving the continuity and safety of the spraying operation.

[0060] The design employing at least two first ports 201 and corresponding connected second ports 101 provides multiple return paths when the liquid level in the supply tank 1 rises. This design not only improves the reliability of liquid level control but also reduces the load on a single overflow channel by increasing the number of return paths, ensuring the smoothness and efficiency of liquid return and avoiding the risk of blockage during overflow.

[0061] This device forms a closed-loop liquid level regulation system through the connection between the first port 201 and the second port 101. This design enables a stable liquid level balance to be established between the supply tank 1 and the storage tank 4. Even when the spraying component 400 continuously outputs antistatic agent, the liquid level in the supply tank 1 can be kept stable through automatic overflow and replenishment processes, thereby ensuring the continuity of spraying operations and a stable supply of antistatic agent.

[0062] The overflow control mechanism of this device reduces reliance on complex level sensors, simplifies the system structure, and lowers the complexity of maintenance and operation. Simultaneously, precise level control and a stable reflux mechanism reduce liquid waste and the frequency of liquid replenishment, thereby further reducing overall operating costs.

[0063] Furthermore, the liquid storage tank 4 is provided with a partition to divide the liquid storage tank 4 into a first tank 401 and a second tank 402, which are arranged along the length of the liquid storage tank 4.

[0064] The first branch port 403 is set on the first housing 401. The first branch port 403 is connected to the first branch pipe 404. The outlet end of the first branch pipe 404 is connected to the liquid supply pipe 2.

[0065] The second branch port 405 is located on the second housing 402. The second branch port 405 is connected to the second branch pipe 406, and the outlet end of the second branch pipe 406 is connected to the liquid supply pipe 2.

[0066] Specifically, a partition is provided inside the liquid storage tank 4, dividing the liquid storage tank 4 into a first tank 401 and a second tank 402 arranged along the length of the liquid storage tank 4. A first branch port 403 is provided on the first tank 401, and the liquid outlet of the first branch port 403 is connected to a first branch pipe 404. The outlet of the first branch pipe 404 is connected to the liquid supply pipe 2. A second branch port 405 is provided on the second tank 402, and the liquid outlet of the second branch port 405 is connected to a second branch pipe 406. The liquid outlet of the second branch pipe 406 is also connected to the liquid supply pipe 2. Liquid is first supplied to the liquid supply tank 1 by one of the first tank 401 and the second tank 402, and the other serves as a supplement.

[0067] By installing a partition inside the liquid storage tank 4, the tank is divided into a first tank 401 and a second tank 402, enabling alternating or selective liquid supply. This design allows the other tank to serve as a supplement or standby while one tank supplies liquid to the main tank, enhancing the flexibility of liquid management and the continuity of supply, ensuring stable control of the liquid level, and avoiding supply interruptions caused by a single empty tank.

[0068] The first chamber 401 and the second chamber 402 are connected to the liquid supply pipe 2 through their respective first branch pipe 404 and second branch pipe 406, which can balance the liquid consumption of the two chambers and seamlessly switch to the other chamber for liquid supply when one chamber needs maintenance or replacement, thus improving the overall stability and reliability of the system.

[0069] The dual-tank liquid supply system incorporates a redundancy mechanism, ensuring that even if one tank or pipeline fails, the other tank can still maintain liquid supply, thus guaranteeing a continuous supply of antistatic agent, reducing the risk of system downtime due to single-point failure, and enhancing the safety of the entire liquid supply device.

[0070] Furthermore, the liquid spraying component 400 has multiple components, which are arranged at intervals along the length of the liquid storage tank 4; and / or,

[0071] The bottom of the liquid supply tank 1 is provided with a liquid inlet 408, and the outlet end of the liquid inlet 408 is connected to one end of the liquid supply pipe 2.

[0072] Specifically, such as Figure 4 As shown, the spraying component 400 has multiple parts, and an inlet pipe 408 is provided at the bottom of the liquid supply tank 1. The inlet pipe 408 is connected to the end of the liquid supply pipe 2 away from the pump body 3. The liquid in the first branch pipe 404 and the second branch pipe 406 is transported from the liquid supply pipe 2 to the liquid supply tank 1.

[0073] The multiple configurations of the spraying components 400 significantly improve the spraying efficiency and coverage at the bottom of the supply tank 1, ensuring that the antistatic agent is sprayed evenly and thoroughly during use, thus improving the efficiency and quality of the spraying operation. This design is particularly suitable for industrial applications requiring large-area, high-density spraying and can meet the demands of high-load operations.

[0074] The connection between the inlet pipe 408 and the supply pipe 2 ensures that the liquid in the first branch pipe 404 and the second branch pipe 406 can be accurately replenished into the supply tank 1, avoiding liquid overflow or waste that may occur in traditional supply systems due to unreasonable supply pipe design, and improving the economy and environmental friendliness of liquid management.

[0075] Furthermore, there are multiple first openings 201, and the arrangement direction of the multiple first openings 201 is perpendicular to the first direction;

[0076] There are multiple second ports 101, and the multiple second ports 101 are distributed along the length of the liquid storage tank 4.

[0077] Each of the first ports 201 and each of the second ports 101 are connected by a first pipe 5, so that when the antistatic agent in the supply tank 1 exceeds a set distance, the antistatic agent is transported from each of the first pipes 5 to the storage tank 4.

[0078] Specifically, there are two first orifices 201 in this application, and the arrangement direction of the two first orifices 201 is perpendicular to... Figure 1In the vertical direction, each first port 201 and each second port 101 are connected by a first pipe 5 so that when the level of the antistatic agent in the supply tank 1 exceeds a set distance, the excess liquid can be transported to the storage tank 4 by overflow through the first pipe 5.

[0079] The two first ports 201 enable more accurate monitoring and control of the liquid level in the supply tank 1. When the liquid level exceeds the set distance, the excess liquid can overflow simultaneously through both first ports 201. Compared to a single port, this allows for faster and more uniform transfer of liquid to the storage tank 4, improving the efficiency and accuracy of overflow control and ensuring the stability of the liquid level in the supply tank 1.

[0080] The bidirectional connection between the two first ports 201 and the liquid storage tank 4 not only provides overflow protection when the liquid level is too high, but also serves as an additional replenishment path when needed, ensuring liquid level control and liquid supply to the supply tank 1 under various operating conditions. This design significantly enhances the redundancy and reliability of the system, reducing the risk of liquid supply interruption due to single point of failure.

[0081] The vertical arrangement of the two first ports 201 helps maintain the pressure balance between the supply tank 1 and the storage tank 4 during the overflow process, avoids the pressure difference problem caused by single port overflow, optimizes the liquid flow state, reduces liquid impact and bubble generation during the overflow process, and improves the stability and accuracy of liquid management.

[0082] Furthermore, the liquid supply device also includes: a liquid level detection component 6, which is installed on the liquid storage tank 4 to detect the real-time liquid level of the antistatic agent in the liquid storage tank 4;

[0083] The supply tank stores antistatic agent. The supply tank is connected to the storage tank 4 and the liquid level detection component 6 respectively, so as to deliver antistatic agent to the storage tank 4 when the real-time liquid level is lower than the set liquid level.

[0084] Specifically, the liquid supply device also includes a liquid level detection component 6 installed on the liquid storage tank 4, such as... Figure 3 As shown, the liquid level detection component 6 in this embodiment is a liquid level gauge, used to detect the real-time liquid level of the antistatic agent in the storage tank 4. It also includes a supply tank storing the antistatic agent. The supply tank is connected to the storage tank 4 and the liquid level detection component 6 respectively. When the liquid level detection component 6 detects that the liquid level of the antistatic agent in the storage tank 4 is lower than the set liquid level, it delivers the antistatic agent to the storage tank 4 through the supply tank to ensure that the storage tank 4 can deliver the antistatic agent to the supply tank 1 in real time, and also to ensure the stability of the antistatic agent liquid level in the supply tank 1. Finally, it ensures that the spraying component 400 can continuously output the antistatic agent for spraying operations.

[0085] The liquid level detection component 6 (liquid level gauge) can monitor the antistatic agent liquid level in the storage tank 4 in real time. Once the liquid level drops below the set level, an early warning mechanism will be activated immediately. This real-time monitoring function ensures the timeliness and continuity of liquid supply, avoids interruption of spraying operations due to insufficient liquid level, and improves production efficiency and stability.

[0086] When the liquid level detection component 6 detects that the liquid level in the storage tank 4 is lower than the set level, the supply tank will automatically start the replenishment process to add antistatic agent to the storage tank 4. This automatic replenishment mechanism not only reduces the frequency of manual intervention and the workload of operators, but also ensures the accuracy and timeliness of the replenishment process, avoids excessive or insufficient liquid supply, and optimizes liquid management and replenishment strategies.

[0087] The automatic replenishment of liquid from the supply tank to the storage tank 4 ensures sufficient liquid in the storage tank 4, thereby guaranteeing that the liquid level in the supply tank 1 is always maintained at the set distance. This stable liquid level control mechanism is crucial for the continuous output of antistatic agent by the spraying component 400 for spraying operations. It can effectively avoid unstable or interrupted spraying operations caused by liquid level fluctuations, thus improving the continuity and reliability of spraying operations.

[0088] Furthermore, the liquid supply device also includes a supply port 407, which is located on the side wall of the liquid storage tank 4. The supply port 407 is connected to the supply tank through a supply pipe so as to deliver the antistatic agent into the supply tank through the supply pipe.

[0089] Specifically, the liquid supply device also includes a supply port 407 provided on the side wall of the liquid storage tank 4. The supply port 407 is connected to the supply tank through a corresponding supply pipe so as to deliver the antistatic agent into the supply tank through the supply pipe.

[0090] The supply port 407 is directly connected to the supply tank, enabling precise delivery of the antistatic agent through the supply pipeline. This design allows for the replenishment of the antistatic agent according to the actual needs of the storage tank 4 and a pre-set replenishment strategy, avoiding liquid waste caused by over-replenishment and preventing the supply tank from malfunctioning due to insufficient replenishment.

[0091] The supply port 407 is located on the side wall of the liquid storage tank 4, which can ensure the rapid and smooth delivery of liquid, reduce the time delay and pressure loss caused by long liquid delivery path or unreasonable pipeline layout, thereby improving the efficiency and reliability of antistatic agent replenishment.

[0092] By directly connecting the supply tank via the supply port 407, the structure of the liquid supply system is simplified, and the number of pipes and interfaces is reduced. This not only reduces the initial investment cost of the equipment but also reduces the workload of maintenance and cleaning, thus lowering long-term operating costs.

[0093] Furthermore, the liquid supply device also includes a drain port 7, which is located on the side wall of the liquid storage tank 4 relatively close to the bottom. The outlet end of the drain port 7 is away from the bottom wall of the liquid storage tank 4 so as to discharge the antistatic agent in the liquid storage tank 4 from the drain port 7.

[0094] Specifically, the liquid supply device also includes a drain port 7 located on the side wall of the liquid storage tank 4, which is relatively close to the bottom of the liquid storage tank 4. The outlet end of the drain port 7 is located away from the bottom of the liquid storage tank 4. When the spraying operation is no longer performed, the antistatic agent in the liquid storage tank 4 can be discharged through the drain port 7.

[0095] The drain port 7 is located on the side wall of the liquid storage tank 4 near the bottom. This design allows for the complete emptying of the antistatic agent from the liquid storage tank 4 after spraying operations have ceased, preventing potential problems such as chemical reactions, contamination, or crystallization blockage caused by liquid residue. This is significant for preventing liquid deterioration, extending equipment lifespan, and reducing cleaning workload during subsequent operations.

[0096] By using the drain port 7, the storage tank can be emptied periodically or as needed, reducing the corrosion of the storage tank 4 and pipes caused by long-term liquid retention, and lowering maintenance frequency and costs. When changing different types of antistatic agents, thorough emptying avoids cross-contamination of chemicals, ensuring the safety and accuracy of subsequent operations.

[0097] Furthermore, the top of the liquid storage tank 4 is also provided with a vent 8 to maintain the air pressure inside the liquid storage tank 4 through the vent 8.

[0098] Specifically, a vent hole 8 is provided on the top of the liquid storage tank 4.

[0099] The vent 8 balances the air pressure inside and outside the liquid storage tank 4. Especially during liquid input or output, the vent allows air to enter and exit freely, preventing pressure changes from affecting liquid flow. This ensures the stable operation of the liquid supply system and avoids reduced liquid pumping efficiency or equipment damage caused by pressure imbalance.

[0100] When the liquid in the storage tank 4 expands slightly due to temperature changes or external vibrations, the vent 8 allows excess gas to escape, thereby preventing liquid from splashing through other undesigned openings (such as pipe openings or pipe connections), reducing liquid waste, and also avoiding potential safety hazards.

[0101] The presence of vent 8 allows fresh air to enter the liquid storage tank 4, which helps to promote the "breathing" of the liquid inside the tank, maintain the freshness and chemical stability of the liquid, especially for those chemicals that are sensitive to oxygen, as adequate air circulation can reduce the risk of oxidation reactions.

[0102] The design of the vent 8 facilitates the internal inspection and maintenance of the liquid storage tank 4. Operators can directly observe or use tools to check the condition inside the tank through the vent 8 without disassembling the entire system, which improves maintenance efficiency and reduces downtime.

[0103] The design of the vent 8 should also take safety into consideration, to prevent harmful gases or flammable and explosive gases from accumulating in the liquid storage tank 4, thereby reducing the risk of fire or explosion and protecting the safety of operators.

[0104] Furthermore, the liquid supply device also includes: an inspection port 9, which is located on the top of the liquid supply tank 1. The inspection port 9 protrudes from the upper surface of the liquid supply tank 1.
