Description

Technical Field

[0001] This utility model relates to the field of potassium nitrate production technology, specifically to a dissolving device for potassium nitrate production. Background Technology

[0002] Potassium nitrate is an inorganic substance, commonly known as saltpeter or nitrate. It is a colorless, transparent orthorhombic or rhombic crystal or white powder. It is odorless, non-toxic, and has a salty taste and a cooling sensation.

[0003] For example, a device for dissolving crude potassium nitrate in potassium nitrate production, as described in announcement number "CN218339617U," facilitates the storage of different cleaning agents and controls the spraying amount by incorporating a metering pump, partition plate, cleaning agent storage tank, and nozzle. The device also expands the spraying range of the cleaning agent by incorporating a guide rod, lead screw, slider, and drive servo motor, resulting in better mixing of the agent and potassium nitrate. Furthermore, the device promotes potassium nitrate dissolution and accelerates mixing with the cleaning agent by incorporating a vibration servo motor, spring, mixing plate, and vibrating rod. The inclusion of a first mixing hole, first mixing plate, second mixing hole, and second mixing plate amplifies the impact of vibration on the dissolution of the cleaning agent and potassium nitrate, improving mixing efficiency and facilitating control of the cleaning agent dosage. The device also exhibits high efficiency in dissolving and mixing potassium nitrate and the cleaning agent. However, the reciprocating lead screw, located in the potassium nitrate dissolution tank, generates corrosive gases during potassium nitrate dissolution, which can damage the lead screw. Additionally, the device's vibration mechanism for stirring the potassium nitrate solution and cleaning agent results in poor stirring efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the above-mentioned device, in which the reciprocating screw is installed in the potassium nitrate dissolving tank, corrosive gas is generated during potassium nitrate dissolution, which will damage the reciprocating screw. At the same time, the above-mentioned device has poor stirring efficiency in stirring the potassium nitrate solution and impurity removal agent through a vibration mechanism. Therefore, this invention proposes a dissolving device for potassium nitrate production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a dissolving device for potassium nitrate production, including a solution tank. A vertical plate is fixedly connected to the upper outer wall of the solution tank. A first servo motor is fixedly connected to the right side of the outer wall of the vertical plate by hot-dip galvanized bolts. A reciprocating screw is fixedly connected to the output shaft of the first servo motor. The outer wall of the reciprocating screw is slidably connected to two sliders. The outer walls of the sliders are fixedly connected to a housing. A stirring mechanism is provided inside the housing. A protective mechanism is provided on the inner side of the vertical plate.

[0006] Preferably, the inner wall of the solution tank is equipped with a diversion pipe, both ends of the reciprocating screw are rotatably connected to the vertical plate through bearings, and the protrusion of the outer shell is slidably connected to the straight rod fixed to the vertical plate.

[0007] Preferably, the protective mechanism includes a baffle and a gasket. Mounting blocks are fixedly connected to all four sides of the baffle. The inner walls of the mounting blocks are threadedly connected to hot-dip galvanized bolts. The outer walls of both ends of the gasket abut against the mounting blocks and the hot-dip galvanized bolts, respectively.

[0008] Preferably, the outer walls of the hot-dip galvanized bolts are threaded to the vertical plate, and the outer walls at both ends of the baffle are in contact with the vertical plate.

[0009] Preferably, the stirring mechanism includes a second servo motor, the output shaft of the second servo motor is fixedly connected to a first helical gear, the outer wall of the first helical gear meshes with the second helical gear, the inner wall of the second helical gear is fixedly connected to a rotating tube, the upper inner wall of the rotating tube is rotatably connected to a flange through a sealed bearing, and the rotating tube is machined with multiple air holes.

[0010] Preferably, the outer wall of the second servo motor is threadedly connected to the housing via hot-dip galvanized bolts, and the outer wall of the rotating tube is rotatably connected to the housing via bearings.

[0011] The present invention proposes a dissolving device for potassium nitrate production, which has the following advantages: through the cooperation of the protective mechanism and the vertical plate, the potassium nitrate solution will generate corrosive gas during the reaction. The corrosive gas flows upward. Since there is a baffle below the reciprocating screw, the lower end of the baffle is arc-shaped, which can guide the corrosive gas to both sides for discharge, thus playing a protective role. The baffle of the protective mechanism blocks the corrosive gas, reducing the corrosion and damage of the corrosive gas to the reciprocating screw.

[0012] Through the cooperation of the stirring mechanism and the external air pump, the flange is connected to the output end of the external air pump, allowing the air pump to deliver air into the dedicated pipe. The flange and the rotating pipe are rotatably connected, so the flange does not rotate when the rotating pipe rotates. Then, the second servo motor is started. The output shaft of the second servo motor rotates, driving the first helical gear to rotate. The rotation of the second helical gear drives the rotating pipe to rotate. The rotation of the rotating pipe drives the crossbar installed on the outer wall of the rotating pipe to rotate, achieving the fusion of the impurity remover and the potassium nitrate solution. At the same time, the air pump is started to deliver gas into the rotating pipe. The rotating pipe rotates and exhausts gas into the potassium nitrate solution through the upper air hole, causing the liquid to tumble and further improving the reaction between the potassium nitrate solution and the impurity remover. Compared with vibration, stirring and gas mixing of potassium nitrate solution and impurity remover is more intense and improves stirring efficiency. Attached Figure Description

The outer walls of the two ends of the gasket 303 are respectively abutted against the mounting block 302 and the hot-dip galvanized bolt 304. The outer walls of the hot-dip galvanized bolt 304 are threadedly connected to the vertical plate 2. The outer walls of the two ends of the baffle 301 are in contact with the vertical plate 2. The baffle can prevent corrosive gases from affecting the reciprocating screw.

[0017] See attached document Figures 1-2 And 5: The stirring mechanism 7 includes a second servo motor 701. The output shaft of the second servo motor 701 is fixedly connected to a first helical gear 702. The rotation of the output shaft of the second servo motor 701 drives the first helical gear 702 to rotate. The outer wall of the first helical gear 702 meshes with the second helical gear 703. The rotation of the first helical gear 702 drives the second helical gear 703 to rotate. The inner wall of the second helical gear 703 is fixedly connected to a rotating tube 705.

The outer wall of the rotating tube 705 is rotatably connected to the outer casing 8 through a bearing. The side of the outer casing 8 is provided with an inspection window.

[0018] Working principle: Potassium nitrate is dissolved during its production.

[0019] Work process: The staff pours the potassium nitrate solution to be dissolved into solution tank 1, and then connects it to the inlet pipe of the diversion pipe 9 through an external water pump. The external water pump draws in the impurity remover (an appropriate amount of barium nitrate solution) and delivers it into the diversion pipe 9. The diversion pipe 9 is installed on the inner wall of solution tank 1 and can deliver the impurity remover into solution tank 1. Then, the external air pump output is connected via flange 704, allowing the air pump to deliver air into the special pipe 705. Flange 704 and the rotating pipe 705 are connected by bearings. The external flange 704 is fixed to the slider 6, so the flange 704 does not rotate when the rotating pipe 705 rotates. Then, the second servo motor 701 is started. The output shaft of the second servo motor 701 rotates, driving the first helical gear 702 to rotate. The rotation of the second helical gear 702 drives the rotating pipe 705 to rotate. The rotation of the rotating pipe 705 drives the crossbar set on the outer wall of the rotating pipe 705 to rotate, achieving the fusion of the impurity remover and the potassium nitrate solution. At the same time, the air pump is started to deliver gas into the rotating pipe 705. The rotating pipe 705 rotates and exhausts gas into the potassium nitrate solution through the upper air hole 706, causing the liquid to tumble and further improving the reaction between the potassium nitrate solution and the impurity remover. The staff starts the first servo motor 4. The output shaft of the first servo motor 4 rotates, which drives the reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 causes the two sliders 6 to move synchronously. The synchronous reciprocating movement of the two sliders 6 drives the outer shell 8 to move back and forth, which in turn drives the stirring mechanism 7 to move back and forth. The movement of the outer shell 8 is limited by the straight rod processed on the vertical plate 2. The linear movement of the outer shell 8 also limits the sliders 6, so that the sliders 6 also move synchronously. The reciprocating movement of the stirring mechanism 7 drives the rotating tube 705 to move back and forth. The rotating tube 705 rotates and moves back and forth at the same time, which better stirs the solution tank 1. Corrosive gas is generated during the reaction of potassium nitrate solution. The corrosive gas flows upward. Since there is a baffle 301 below the reciprocating screw 5, the lower end of the baffle 301 is arc-shaped, which can guide the corrosive gas to both sides to be discharged, thus playing a protective role. If the baffle 301 needs to be replaced, it can be done by turning the hot-dip galvanized bolt 304 to separate the hot-dip galvanized bolt 304 from the washer 303 and the vertical plate 2. Without the hot-dip galvanized bolt 304 fixing it, the baffle 301 can be directly removed, and the baffle 301 can be replaced or cleaned. After dissolution is complete, the staff opens the valve on the discharge pipe of solution tank 1 to discharge and collect the dissolved potassium nitrate solution, and then filters it to filter out potassium nitrate crystals. The staff then manually removes and collects the potassium nitrate crystals remaining in solution tank 1.
