Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of silver sulfate processing, and particularly relates to a silver sulfate processing device, a liquid inlet adjusting mechanism and an adjusting method. BACKGROUND

[0002] Silver sulfate is an important inorganic compound and is widely used in the fields of chemistry, pharmacy and catalysis. As a silver sulfate, silver sulfate has excellent corrosion resistance and catalytic performance and is often used in catalytic reactions, oxidation reactions and metal recovery processes.

[0003] The traditional silver sulfate production process is to generate silver sulfate solution by reacting silver nitrate with sulfuric acid, and to obtain crystals after hydrolysis treatment. Generally, an intermittent reaction kettle is used to make sulfuric acid and silver nitrate undergo a double decomposition reaction to generate silver sulfate and nitric acid, and then nitrate is removed through evaporation, water washing and the like.

[0004] However, in the existing reaction kettle, the liquid inlet pipe of the silver sulfate reaction kettle often adopts a straight pipe or a short pipe structure, and the outlet end thereof is usually suspended above the reaction liquid surface. This design causes the liquid material to flow out of the liquid inlet pipe at a high speed when the liquid material falls from a large height and lacks buffering, and the liquid flow directly impacts the liquid surface or the inner wall of the reaction kettle, causing severe splashing. The splashing not only causes uneven distribution of the material, but also can cause a large amount of gas to be entrained in the reaction liquid to form fine bubbles that are difficult to escape. These bubbles exist in the reaction system and can interfere with the uniform contact between silver ions and sulfate ions, affecting the nucleation and growth of the crystallization process, resulting in a wide size distribution of silver sulfate crystals and a reduction in purity. If the liquid outlet of the liquid inlet pipe is directly below the reaction liquid surface, part of the liquid will be left in the liquid inlet pipe, causing uneven reaction. For the bottom liquid inlet mode, if the feed needs to be delivered at high pressure, the high pressure of the bottom liquid inlet will directly act on the bottom of the reaction kettle, increasing the pressure load of the equipment, and additional reinforcement of the kettle bottom is required, increasing the cost.

[0005] Therefore, it is necessary to design a silver sulfate processing device, a liquid inlet adjusting mechanism and an adjusting method to solve the technical problem that the short liquid inlet pipe in the prior art easily causes the reaction liquid to splash and generate bubbles that affect the subsequent reaction.

[0006] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background of the present application, and therefore, the above description is not considered to constitute information of the prior art. SUMMARY

[0007] The embodiments of the present disclosure at least provide a silver sulfate processing device, a liquid inlet adjusting mechanism and an adjusting method.

[0008] In a first aspect, the embodiments of the present disclosure provide a silver sulfate processing device, comprising: a reaction kettle, an internal liquid inlet mechanism is arranged in the reaction kettle; wherein The liquid inlet mechanism comprises at least one liquid inlet pipe, and a liquid outlet is formed on the outer wall of the liquid inlet pipe; a plurality of liquid inlet adjusting mechanisms, each of which is arranged inside a corresponding liquid inlet pipe, and each of the liquid inlet adjusting mechanisms comprises: a moving piece, the upper end surface of which is adapted to buffer the liquid flowing from top to bottom in the liquid inlet pipe when the moving piece is slid inside the liquid inlet pipe to below the liquid outlet; and the moving piece is adapted to block the liquid outlet when the moving piece is slid to be coplanar with the liquid outlet.

[0009] In an alternative embodiment, the bottom of each of the liquid inlet pipes is provided with a rotating piece, and the upper end surface of the rotating piece is provided with a guide sleeve; wherein the guide sleeve is located inside the liquid inlet pipe; and at least one guide groove is formed on the outer wall of the guide sleeve.

[0010] In an alternative embodiment, a driving rod is inserted into the inside of the moving piece; wherein a driving shaft is horizontally arranged inside the driving rod, and at least one end of the driving shaft penetrates through the driving rod and is located outside the driving rod; the end of the driving shaft located outside the driving rod is located in the guide groove.

[0011] In an alternative embodiment, the moving piece is annular, and the diameter of the moving piece is consistent with the inner diameter of the liquid inlet pipe; the diameter of the driving rod is slightly smaller than the diameter of the moving piece.

[0012] In an alternative embodiment, at least one spiral groove is formed on the inner wall of the liquid inlet pipe; wherein the end of the driving shaft located outside the driving rod penetrates through the guide groove and is located in the spiral groove.

[0013] In a second aspect, the embodiments of the present disclosure also provide a liquid inlet adjusting mechanism for a silver sulfate processing device, comprising: a moving piece, which is slidably arranged inside a corresponding liquid inlet pipe; the upper end surface of the moving piece is adapted to buffer the liquid flowing from top to bottom in the liquid inlet pipe when the moving piece is slid inside the liquid inlet pipe to below the liquid outlet; and the moving piece is adapted to block the liquid outlet when the moving piece is slid to be coplanar with the liquid outlet.

[0014] In an alternative embodiment, the bottom of each of the liquid inlet pipes is provided with a rotating piece, and the upper end surface of the rotating piece is provided with a guide sleeve; wherein the guide sleeve is located inside the liquid inlet pipe; and At least one guide groove is provided on the outer wall of the guide sleeve.

[0015] In one alternative embodiment, a drive rod is internally inserted into the moving member; wherein A drive shaft is horizontally arranged inside the drive rod, and at least one end of the drive shaft passes through the drive rod and is located outside the drive rod; The end of the drive shaft located outside the drive rod is located inside the guide groove.

[0016] In one alternative embodiment, the movable element is annular and the diameter of the movable element is the same as the inner diameter of the inlet pipe; The diameter of the drive rod is slightly smaller than the diameter of the moving part; At least one spiral groove is formed on the inner wall of the inlet pipe; wherein The end of the drive shaft located outside the drive rod passes through the guide groove and is located within the spiral groove.

[0017] Thirdly, embodiments of this disclosure also provide a method for adjusting a liquid inlet regulating mechanism for a silver sulfate processing apparatus, the method comprising: By rotating the rotating component in the forward direction, the guide sleeve is rotated, which in turn pushes the drive shaft that passes through the guide groove to move along the guide direction of the spiral groove, thereby causing the moving component to move downward along the axial direction of the liquid inlet pipe. By adjusting the movable part to be below the liquid outlet, the liquid in the inlet pipe flows from top to bottom, impacts the upper end face of the movable part for cushioning, and then flows out from the liquid outlet. By rotating the rotating component in the opposite direction, the moving component is driven to move upward along the axis of the inlet pipe to clean the inner wall of the inlet pipe until the moving component and the outlet are coplanar and block the outlet.

[0018] The beneficial effect of this invention is that the device is equipped with a liquid inlet mechanism and a liquid inlet regulating mechanism that cooperates with each liquid inlet pipe in the liquid inlet mechanism. The liquid outlet on the outer wall of the liquid inlet pipe is located inside the reaction vessel and below the liquid surface of the reaction solution. By controlling the position of the moving part in the liquid inlet regulating mechanism in the corresponding liquid inlet pipe, when the moving part is moved to below the liquid outlet, the liquid flowing in the liquid inlet pipe will preferably impact the upper end surface of the moving part for buffering, and then be discharged from the liquid outlet. This avoids splashing caused by the excessive flow rate when directly exiting the liquid outlet, which would otherwise cause a large amount of gas to be entrained in the reaction solution.

[0030] Research has revealed that in existing reaction vessels, the inlet pipe of a silver sulfate reactor often uses a straight or short pipe structure, with its outlet typically suspended above or near the surface of the reaction liquid. This design causes the liquid material to flow out of the inlet pipe at high speed, directly impacting the liquid surface or the inner wall of the reaction vessel due to the large drop and lack of buffering. This results in violent splashing, which not only leads to uneven material dispersion but also entrains a large amount of gas into the reaction liquid, forming tiny bubbles that are difficult to escape. These bubbles, present in the reaction system, interfere with the uniform contact between silver ions and sulfate ions, affecting the nucleation and growth of the crystallization process. This results in a wider distribution of silver sulfate crystal size and a decrease in purity. Conversely, if the outlet of the inlet pipe is placed directly below the surface of the reaction liquid, some liquid will remain inside the inlet pipe, leading to uneven reaction.

[0031] Based on the above research, this disclosure provides a silver sulfate processing apparatus, a liquid inlet regulating mechanism, and a regulating method. The apparatus includes a liquid inlet mechanism and a liquid inlet regulating mechanism that cooperates with each liquid inlet pipe within the liquid inlet mechanism. The outlet on the outer wall of the liquid inlet pipe is located inside the reactor and below the surface of the reaction solution. By controlling the position of the moving part in the liquid inlet regulating mechanism within the corresponding liquid inlet pipe, when the moving part moves below the outlet, the liquid flowing through the liquid inlet pipe preferentially impacts the upper surface of the moving part for buffering, and then exits from the outlet. This avoids excessively fast flow at the outlet, which could cause splashing and thus entrain a large amount of gas into the reaction solution.

[0032] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] In some embodiments, such as Figs. 1-2As shown, the core components of the silver sulfate processing unit include a reaction vessel 1 and a liquid inlet mechanism 2. The reaction vessel 1, as the reaction container, is typically made of corrosion-resistant materials (such as stainless steel or fiberglass) to adapt to the environment in silver sulfate production. The liquid inlet mechanism 2 consists of at least one inlet pipe 20, each with an inlet port 201 at its top for introducing the solution required for the reaction, such as silver nitrate solution or sulfuric acid solution. The material of the inlet pipe 20 must have high chemical stability; common choices are polytetrafluoroethylene (PTFE) or Hastelloy to avoid solution corrosion. The inlet pipe 20 is installed vertically through the top and bottom of the reaction vessel 1, with connections sealed by welding or flanges to ensure isolation between the inside and outside of the reaction vessel, preventing leakage or contamination. Each inlet pipe 20 has an outlet port 200 on its outer wall, located below the surface of the final reaction mixture. This avoids direct impact on the liquid surface, allowing the solution to release slowly from below, reducing splashing.

[0036] In some embodiments, such as Figs. 3-5 As shown, the core of the liquid inlet regulating mechanism 3 lies in achieving buffering and flow control of the solution through mechanical adjustment. Before each solution is introduced into the inlet pipe 20, the operator needs to adjust the position of the moving part 33. In specific operation, the operator rotates the rotating part 30 in the forward direction (the rotating part 30 is usually a handwheel or electric actuator, and its driving method includes manual rotation or motor drive, which is existing technology and will not be described in detail in this document). The upper end face of the rotating part 30 is connected to the lower end face of the inlet pipe 20 through a bearing. When the rotating part 30 is rotated in the forward direction (e.g., clockwise), it will drive the guide sleeve 31 fixed on its upper end to rotate synchronously. The guide sleeve 31 has a cylindrical structure, and at least one guide groove 310 is opened on its outer wall. The guide groove 310 is straight in shape to guide the movement trajectory. A drive shaft 320 is horizontally arranged inside the drive rod 32. Both ends of the drive shaft 320 pass through the drive rod 32 and extend to the outside. Its material is usually high-strength steel to withstand torque. The end of the drive shaft 320 passes through the guide groove 310 and is located in the spiral groove 21 opened on the inner wall of the liquid inlet pipe 20. The spiral groove 21 is a threaded groove. When the guide sleeve 31 rotates, the guide groove 310 pushes the drive shaft 320 to move along the guiding direction of the spiral groove 21. Due to the spiral characteristics of the spiral groove 21, the drive shaft 320 moves downward along the axial direction of the liquid inlet pipe 20 while rotating, thereby driving the drive rod 32 and the moving part 33 to move downward synchronously. When the upper surface of the moving part 33 moves below the outlet 200 (its position can be precisely calibrated using a scale or sensor), its buffering effect begins to take effect. The moving part 33 is annular, with a diameter consistent with the inner diameter of the inlet pipe 20 (tolerance controlled within ±0.1 mm). As the solution flows from top to bottom within the inlet pipe 20, it preferentially impacts the upper surface of the moving part 33. The upper surface of the moving part 33 can be designed as a slope or concave shape to disperse the impact force of the liquid flow. The buffered solution then slowly flows out from the outlet 200 and enters the submerged region of the reactor 1. Compared to the existing short-pipe direct supply technology (whose outlet is usually located on the liquid surface, and the liquid flow impacts the liquid surface at high speed, generating splashes and bubbles), this design significantly reduces the risk of gas entrapment.

[0037] In some embodiments, such as Figs. 5-6 As shown, when the amount of solution added approaches the preset value (monitored by a flow meter or weight sensor), the operator needs to adjust the moving part 33 in the reverse direction to achieve the blocking and cleaning functions; By rotating the rotating component 30 in the opposite direction (e.g., counterclockwise), the reverse rotation of the guide sleeve 31 drives the drive shaft 320 to move upward along the spiral groove 21. The drive shaft 320 then drives the drive rod 32 and the moving component 33 to move upward along the axis of the inlet pipe 20. This process is continuously adjustable: the moving component 33 is initially located below the outlet 200. As it moves upward, it gradually approaches the outlet 200, partially blocking the opening of the outlet 200, thereby reducing the effective outflow area and thus reducing the flow rate. When the movable component 33 moves completely upward to be coplanar with the outlet 200, its annular structure tightly seals the outlet 200, forming a mechanical seal. The diameter of the movable component 33 is consistent with the inner diameter of the inlet pipe 20, ensuring the tightness of the seal. At this time, the interior of the inlet pipe 20 is isolated from the space of the reactor 1, and the residual solution is sealed within the inlet pipe 20, preventing it from entering the reactor 1. This solves the "siphon residue" problem caused by liquid discharge from below in the prior art—that is, due to liquid surface pressure, some solution remains in the inlet pipe, affecting the uniformity of the reaction. At the same time, during the upward movement of the movable component 33, its outer wall contacts the inner wall of the inlet pipe 20, generating a scraping effect, which can clean the particles (such as undissolved salts or impurities) attached to the inner wall, preventing scale buildup from affecting long-term use.

[0038] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0039] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0040] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0041] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
