Description

Technical Field

[0001] This application relates to the field of liquid supply structure technology, and specifically discloses a liquid supply structure for a liquid spraying system. Background Technology

[0002] A liquid supply system is a device used to supply liquid to a system or equipment during the production process; a liquid spraying system is a device and its accessories used to spray liquid during the production process.

[0003] Quenching is a metal heat treatment process in which a metal workpiece is heated to a suitable temperature and held for a period of time, then rapidly cooled by immersion in a quenching medium. Commonly used quenching media include brine, water, mineral oil, and air. Quenching can improve the hardness and wear resistance of metal workpieces.

[0004] Therefore, in the quenching process, a liquid spraying system is needed to achieve rapid cooling, and a related liquid supply structure is used to cooperate with the liquid spraying system to achieve rapid cooling.

[0005] Current problems: In quenching, water quenching or oil quenching are the most common methods, and immersion quenching is often used. Therefore, the liquid spraying system at this time is usually to inject the quenching medium into the container. The structure of injection is the liquid spraying system. It is used after the container reaches a certain depth.

[0006] The biggest problem with long-term quenching is that the shapes of the quenched workpieces are different, meaning the depth of the quenching medium in the corresponding container is different. This leads to a very critical issue: when a small but dense workpiece enters the quenching medium, because the previous workpiece required a deeper quenching medium depth to ensure complete quenching, when the subsequent small but dense workpiece enters the quenching medium, the quenching medium is prone to overflowing from the container. Therefore, it is necessary to reasonably adjust the depth of the quenching medium. In view of this, the inventor has developed a liquid supply structure for a liquid spraying system. Utility Model Content

[0007] The purpose of this invention is to solve the problem that traditional liquid supply structures cannot reasonably adjust the depth of the quenching medium in the container.

[0008] To achieve the above objectives, this utility model provides the following basic solution:

[0009] A liquid supply structure for a spraying system includes several liquid supply components arranged around a container.

[0010] The liquid supply assembly includes a liquid supply cylinder, an injection cylinder connected to the liquid supply cylinder, a discharge cylinder connected to the injection cylinder, an injection component disposed on the injection cylinder, and a discharge component disposed on the discharge cylinder. Both the injection component and the discharge component are connected to a container. The discharge component is provided with a lifting component for moving the cooling medium. One end of the lifting component is connected to the discharge component, and the other end of the lifting component is connected to the liquid supply cylinder.

[0011] The principle and effect of this basic scheme are as follows:

[0012] 1. Compared with existing technologies, this device has a simple structure and ingenious design. The core of this device is the injection and recovery of the cooling medium. By using the injection and recovery of the cooling medium, the depth of the cooling medium in the container can be reasonably adjusted, so that during quenching, full coverage quenching can be achieved for different quenching products, and the overflow of the cooling medium is not easy. This device solves the problem that traditional liquid supply structures cannot reasonably adjust the depth of the quenching medium in the container.

[0013] 2. Compared with existing technologies, the quenching medium can be reused. Inorganic quenching fluid has the characteristics of high chemical stability, no deterioration, long service life, safety, no pollution, and high efficiency and energy saving. It will not produce reverse solubility and adhere to the workpiece surface, causing a large amount of quenching agent waste. During use, mainly water evaporates, and the amount carried away by the medium is very small. Therefore, even if it is not used for a long time and is not maintained, the quenching fluid will not deteriorate. Therefore, the recovery of the cooling medium will not affect the replenishment of new cooling medium, and new and old cooling media can be mixed and used.

[0014] 3. Compared with the prior art, this device utilizes an injection component and a discharge component to achieve flexible adjustment of the depth of the cooling medium in the container, thereby making the cooling medium suitable for most workpieces that require quenching, and ensuring that the cooling medium does not overflow.

[0015] 4. Compared with the prior art, the injection cylinder and discharge cylinder are set based on the injection component and discharge component, which realizes the reuse of cooling medium and new cooling medium. When the cooling medium is not used for a long time, it can be placed in the supply cylinder and injection cylinder to avoid the mixing of impurities when it is not used.

[0016] Furthermore, the liquid supply cylinder has a cylindrical structure, with a liquid supply port at the top, a sealing cap at the liquid supply port, and a scale around the perimeter of the liquid supply cylinder.

[0017] Furthermore, the injection device includes an injection tube and a first mechanical switch valve disposed on the injection tube. The first mechanical switch valve is used to open and close the injection tube. One end of the injection tube is connected to the injection cylinder, and the other end of the injection tube is connected to the container. The discharge device includes a discharge tube and a second mechanical switch valve disposed on the discharge tube. The second mechanical switch valve is used to open and close the discharge tube. One end of the discharge tube is connected to the discharge cylinder, and the other end of the discharge tube is connected to the container.

[0018] Furthermore, the discharge cylinder and the injection cylinder are welded together, and a partition is provided at the weld joint between the discharge cylinder and the injection cylinder. The partition is used to separate the internal spaces of the discharge cylinder and the injection cylinder.

[0019] Furthermore, the injection tube is located in the upper middle section of the container, and the discharge tube is located in the lower section of the container.

[0020] Furthermore, the lifting assembly includes a lifting pump, a connecting pipe, a conduit, and an injector. The injector is connected to the liquid supply cylinder. One end of the conduit is connected to the injector, and the other end of the conduit is connected to the output end of the lifting pump. The input end of the lifting pump is connected to the connecting pipe, and the free end of the connecting pipe is located at the bottom of the discharge cylinder.

[0021] Furthermore, a guide pipe is provided between the liquid supply cylinder and the injection cylinder. Attached Figure Description

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The reference numerals in the accompanying drawings include: container 1, injection pipe 2, baffle 3, discharge cylinder 5, discharge pipe 6, second mechanical switch valve 7, guide pipe 8, injection pipe 9, first mechanical switch valve 10, liquid supply cylinder 11, liquid supply port 12, injector 13, lift pump 14, and conduit 15.

[0027] Implementation, for example Figure 1 and Figure 2 As shown:

[0028] A liquid supply structure for a spraying system includes several liquid supply components arranged around a container 1.

[0029] The liquid supply assembly includes a liquid supply cylinder 11, an injection cylinder connected to the liquid supply cylinder 11, a discharge cylinder 5 connected to the injection cylinder, an injection component disposed on the injection cylinder, and a discharge component disposed on the discharge cylinder 5. The injection component and the discharge component are both connected to the container 1. The discharge component is provided with a lifting component for moving the cooling medium. One end of the lifting component is connected to the discharge component, and the other end of the lifting component is connected to the liquid supply cylinder 11.

[0030] The discharge cylinder 5 is welded to the injection cylinder. A partition 3 is provided at the welding point between the discharge cylinder 5 and the injection cylinder. The partition 3 is used to separate the internal space of the discharge cylinder 5 and the injection cylinder. In order to facilitate observation of the position of the partition 3, the partition 3 extends towards the external position of the discharge cylinder 5 and the injection cylinder.

[0031] Specifically:

[0032] The liquid supply cylinder 11 has a cylindrical structure. A liquid supply port 12 is located at the top of the liquid supply cylinder 11, and a sealing cap is provided at the position of the liquid supply port 12. A scale is provided around the perimeter of the liquid supply cylinder 11. The liquid supply cylinder 11 serves as a coolant supply component, used for replenishing and recovering the coolant. The purpose of the scale is to allow users to determine the storage depth of the liquid supply cylinder 11 (which is often transparent for ease of use), thus preventing overfilling and potential overflow of the coolant.

[0033] The injection device includes an injection tube 2 and a first mechanical switch valve 10 disposed on the injection tube 2. The first mechanical switch valve 10 is used to open and close the injection tube 2. One end of the injection tube 2 is connected to the injection cylinder, and the other end of the injection tube 2 is connected to the container 1. The discharge device includes a discharge tube 6 and a second mechanical switch valve 7 disposed on the discharge tube 6. The second mechanical switch valve 7 is used to open and close the discharge tube 6. One end of the discharge tube 6 is connected to the discharge cylinder 5, and the other end of the discharge tube 6 is connected to the container 1.

[0034] Specifically: such as Figure 1 As shown, the injection pipe 2 is located in the upper middle section of the container 1, the discharge pipe 6 is located in the lower section of the container 1, and the other end of the injection pipe 2 is the bottom of the injection cylinder, which facilitates the rapid outflow of the cooling medium.

[0035] By setting up injection and discharge components, the liquid level of the cooling medium in container 1 is varied, thereby enabling the quenching of workpieces of different sizes.

[0036] To accommodate the injection and discharge components, this device is equipped with a lifting assembly, which includes a lifting pump 14, a connecting pipe, a conduit 15, and an injector 13. The injector 13 is connected to the supply cylinder 11. One end of the conduit 15 is connected to the injector 13, and the other end of the conduit 15 is connected to the output end of the lifting pump 14. The input end of the lifting pump 14 is connected to the connecting pipe, and the free end of the connecting pipe is located at the bottom of the discharge cylinder 5.

[0037] Since the cooling medium can be reused, a booster pump 14 is provided to return the cooling medium to the supply cylinder 11, so that it can be reused or reused with new replenished cooling medium.

[0038] Specific implementation process:

[0039] The first step is that since quenching completely covers the workpiece, different workpieces should have different liquid levels of the cooling medium to ensure that the quenching completely covers the workpiece. If the liquid level is too high when the preceding workpiece is small, there is a risk of the cooling medium overflowing. Therefore, the discharge part and the lift pump 14 are opened to return the cooling medium to the supply cylinder. A guide pipe 8 is provided between the supply cylinder 11 and the injection cylinder. A third mechanical switch valve is provided on the guide pipe 8. At this time, the liquid level of the cooling medium decreases.

[0040] The second step is to reduce the risk of cooling medium overflow. If the subsequent workpiece is a small workpiece, and the liquid level is too high at this time, it still needs to be adjusted downwards to reduce the risk of cooling medium overflow while ensuring full coverage of the workpiece.

[0041] The third step is to open the injection port and raise the liquid level if the liquid level is too low, in order to ensure that the liquid level fully covers the workpiece and that the cooling medium does not overflow.

[0042] This device solves the problem that traditional liquid supply structures cannot reasonably adjust the depth of the quenching medium in container 1.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
