[0031] To address the aforementioned problems, this application provides a liquid chemical reagent preparation device. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0032] In one embodiment, a liquid chemical reagent preparation device is disclosed, comprising: a storage device, a temperature control system, a liquid inlet / outlet device, and a stirring mechanism 9; a liquid collection tank 11 is constructed at one bottom corner of the storage device, a stirring mechanism is provided inside the storage device, a temperature control system is provided outside the storage device to enclose the storage device, and a liquid inlet / outlet device is provided on the storage device to communicate with the storage device, wherein the liquid outlet port of the liquid inlet / outlet device is located in the liquid collection tank 11.

[0033] In this application, the storage device is available in two materials: thickened glass or thickened PP, which can be selected according to the different chemical reagents being prepared. A downward-facing groove is provided at one corner of the bottom of the storage device as a collection tank 11, facilitating thorough collection during dispensing. The top is a cover with a stirring port and a liquid inlet; the edge of the cover has an extended edge that fits into the interior of the storage tank to prevent reagent condensation and dripping onto the outside of the storage device.

[0034] The temperature control system of this application is a double-layered, hollow, sealed container that partially encloses the storage device, covering the bottom and sides. The hollow section contains cooling water and has two inlet / outlet ports, one on the bottom and the other on the top, each connected to a long flexible hose. A water pump is located in the middle to circulate the cooling water. The other end of the hose is immersed in an external water tank containing an ice-adding port and a heating element, allowing for cooling or heating according to the environmental requirements of chemical reagent preparation. The bottom is covered with an anti-slip layer, such as a rubber layer.

[0035] The liquid inlet and outlet device of this application includes two sets of quantitative filling pumps fixed on a bracket or cover. The inlet pump pipe of one set of filling pumps is outside the storage device and has a filter at the end for drawing the required reagent or water. The outlet pump pipe is fixed along the inner wall at the top of the storage device and the nozzle is in the shape of a shower head to allow the liquid to flow along the inner wall. The inlet pump pipe of the other set of filling pumps is fixed in the groove at the bottom of the storage device, and the outlet pump pipe is outside the storage device so that the prepared reagent can be removed.

[0036] The present application has a motor located at the center of the end of the storage device. The working end of the motor is coaxially connected to one end of a rotating rod and is connected to a stirring assembly and placed in the middle of the storage device.

[0037] In this application, a bracket is used to support the components. The bracket is higher than the storage device and is used to fix the stirring device and the liquid inlet / outlet device. The steel frame structure is covered with rubber to prevent acid and alkali corrosion.

[0038] The entire device can have some components added or removed depending on the chemical reagents used, and can be placed or connected to the ventilation system when necessary.

[0039] This application describes a configuration environment for a temperature-controlled system. Reagents are metered into a storage device via a filling pump inlet. After metered intake of the required amount of reagent or water, a stirring device mixes the reagents. Once prepared, the reagents are metered or completely transferred to dispensing bottles via a filling pump outlet. The entire process separates the reagent reaction zone from the inlet, preventing splashing during vigorous reactions, reducing the need for reagent pouring, minimizing the possibility of spillage, and protecting the health of workers. This system replaces manual labor, reducing workload and increasing efficiency.

[0040] In one embodiment, such as Figure 1 A liquid chemical reagent preparation device is shown, comprising: a storage device, a temperature control system, a liquid inlet / outlet device, and a stirring mechanism 9; a liquid collection tank 11 is constructed at one corner of the bottom of the storage device, and the bottom of the storage device is inclined towards the liquid collection tank 11 to facilitate liquid collection. A stirring mechanism is installed inside the storage device, and a temperature control system is installed outside the storage device to enclose it. A liquid inlet / outlet device is installed on the storage device to connect to it, wherein the outlet port of the liquid inlet / outlet device is located within the liquid collection tank 11. The storage device includes an inner storage device 1 and an outer storage device 2. The liquid collection tank 11 is constructed at one corner of the inner storage device 1. A water outlet pipe 21 is constructed on one side of the outer storage device 2, and a water inlet pipe 22 is constructed on the other side. The inner storage device 1 is embedded within the outer storage device 2, with a gap between them. This gap is filled with water as a temperature control medium, and the temperature is stably regulated by the temperature control system. Specifically, the temperature control system includes a circulating pump 4, a coal heating tank 5, and a refrigerant tank 6. The inlet of the circulating pump 4 is connected to both the coal heating tank 5 and the refrigerant tank 6 via a pipe. The coal heating tank 5 contains an electric water heater, and the refrigerant tank 6 contains ice. When the circulating pump 4 operates, it draws water from the external storage device 2 for circulation. Depending on the specific temperature control requirements, the water flow can be heated by passing through the electric water heater in the coal heating tank 5 or cooled by passing through the ice in the refrigerant tank 6. The temperature of the internal storage device 1 is controlled by the circulation of the circulating pump 4, which heats or cools the water. Therefore, the outlet of the circulating pump 4 needs to be connected to the inlet pipe 22, and the outlet pipe 21 needs to be connected to both the coal heating tank 5 and the refrigerant tank 6 via a pipe. Appropriate valves are installed on the pipes to control the flow.

[0041] The liquid inlet and outlet device of this application includes an inlet pump 7 and a dispensing pump 8. The inlet pump 7 has an inlet pipe 71 connected to its inlet end and an inlet / outlet pipe 72 connected to its outlet end. The end of the inlet pipe 71 is placed in the collection tank 11. During operation, the inlet pump 7 draws out the prepared solution from the inner storage device 1 and discharges it into a prepared container through the inlet / outlet pipe 72. The dispensing pump 8 has a dispensing pipe 81 connected to its outlet end and a dispensing pipe 82 connected to its inlet end. The dispensing pipe 81 is suspended inside the storage device. During operation, the dispensing pump 8 operates, and the dispensing pipe 82 draws in the pre-prepared solution to be prepared and adds it to the inner storage device 1 through the dispensing pipe 81 for mixing. After preparation, the solution is drawn out by the inlet pump 7 and bottled.

[0042] In this application, the end of the liquid inlet pipe 71 is provided with a filter head 73 and placed in the liquid collection tank 11; the end of the liquid inlet pipe 81 is connected to a shower head 83, which faces the side wall of the inner storage device 1.

[0043] This application utilizes a two-layer container system: one layer serves as the preparation container, while the other acts as a temperature-controlled container enclosing it. During solution preparation, a temperature control system regulates the ambient temperature. Two separate inlet and outlet devices handle liquid intake and discharge. The entire preparation and dispensing process can be operated via the equipment, requiring only personnel to control the relevant devices. This eliminates the need for reagent pouring, reduces the possibility of spillage, protects worker health, and lowers safety risks associated with preparation operations. Furthermore, by replacing manual labor with machines, it reduces workload and increases efficiency.

[0044] In one embodiment, such as Figure 1 As shown, to facilitate configuration and observation while preventing solution splashing, and also to facilitate the placement of components as replacement supports, this application provides a transparent cover 3 on the top of the storage device. Furthermore, the inlet pump 7, the dispensing pump 8, and the stirring mechanism 9 are mounted on the cover 3. Thus, by using the transparent cover 3 instead of a support, the observation requirements are met, some equipment can be placed on it, and the internal storage device 1 is well protected, preventing solution splashing during configuration.

[0045] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.
