Description

Technical Field

[0001] The utility model relates to a drying crystallization technology, in particular to a drying crystallization device for a cuprous cyanide finished product. Background Art

[0002] Cuprous cyanide is mainly used in industrial production for electroplating copper and its alloys. In addition, it is also used in medicine as a raw material for anti-tuberculosis drugs and other drugs, in the manufacture of pesticides and other chemical agents, in the purification of molten metals, and in the manufacture of antifouling coatings.

[0003] The main method for preparing cuprous cyanide is the copper sulfate method, which is to dissolve sodium cyanide, copper sulfate, and sodium sulfite in sodium carbonate solution respectively, separate the impurities through sedimentation, and then combine them together to react. Sulfuric acid is used to neutralize the alkalinity and adjust the pH value to generate cuprous cyanide precipitate, which is then rinsed, separated, and finally dried and crystallized to obtain the finished product. The crystallized product is generally refined to form a powder.

[0004] In the last process of cuprous cyanide production, a crystallization kettle is generally used to dry and evaporate the solvent in the cuprous cyanide solution to obtain a solid crystal solute. The crystallization kettle used for batch production of cuprous cyanide in the industry is currently very large, and the amount of crystallization per time is also large. It contains a heating device and a stirring device, etc. The stirring device is mainly used to mix the solution in the kettle, accelerate heat exchange, and avoid heat accumulation near the heating device at the bottom of the kettle, resulting in uneven heating of the upper solution.

[0005] The structures of stirring machines are similar. They all have a central axis with multiple impellers fixed on the central axis to form an impeller group. When the equipment is running, the central axis is driven to rotate by an externally installed power device to drive the impeller group to rotate. However, as the solvent continues to evaporate, the liquid level in the kettle will continue to decrease, and a suspended impeller will be generated on the upper part, and the suspended impeller will run without load. Because the kettle is large in size and the impeller is also large, the externally installed power device needs to output a large torque to drive the entire impeller group to rotate, and a considerable part of it needs to be shared by the no-load impeller, resulting in high energy consumption of the overall equipment.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] See also Figure 1 to Figure 9 As an embodiment of the utility model, the drying and crystallization equipment of the cuprous cyanide product comprises a stirring assembly and a kettle structure, wherein the stirring assembly and the kettle structure form a crystallization kettle; the stirring assembly comprises a rotating sleeve 16, and a plurality of blades 13 are fixed on the outer wall of the rotating sleeve 16, and the plurality of blades 13 surround the outer periphery of the rotating sleeve 16 to form an impeller;

[0035] The rotating sleeve 16 is connected to the transmission shaft 11 through a clutch structure, and the transmission shaft 11 is rotatably arranged in the kettle body structure. A motor 3 is also fixedly installed on the top of the kettle body structure, and the output shaft of the motor 3 is connected to the transmission shaft 11;

[0036] When the liquid level in the kettle structure is higher than the impeller, the rotating sleeve 16 can be combined with the transmission shaft 11 through the clutch structure;

[0037] When the liquid level in the kettle structure is lower than the impeller, the rotating sleeve 16 is disconnected from the transmission shaft 11 .

[0038] In this embodiment, the clutch structure can automatically adjust the engagement and disconnection of the impeller and the transmission shaft 11 according to the liquid level; it should be noted that a plurality of impellers of different heights are arranged in the axial direction of the transmission shaft 11. When the liquid level is higher than the height of the current impeller, the impeller is engaged with the transmission shaft 11. At this time, the transmission shaft 11 is driven to rotate under the action of an external power device, and the impeller engaged with the transmission shaft 11 can also rotate. The rotation of the impeller stirs and mixes the cuprous cyanide solution in the kettle structure, so that the heat at the bottom of the kettle structure can be conducted upward, accelerating the evaporation rate of water in the upper solution, thereby improving the thermal conductivity of crystallization.

[0039] When the liquid level is lower than the current impeller height, the impeller is disconnected from the transmission shaft 11. At this time, the external power device will only drive the transmission shaft 11 to rotate, and the impeller at the current height will not rotate, thereby reducing the load of the external power device and having an energy-saving effect.

[0040] As a further solution of the utility model, the clutch structure includes a rotating disk 14 fixedly mounted on the transmission shaft 11, and a circle of tooth grooves is provided below the rotating disk 14;

[0041] The transmission shaft 11 further includes a float 15 sleeved on the outer wall of the transmission shaft 11 , and a plurality of traction columns 17 are fixedly mounted on the float 15 , and the traction columns 17 can be engaged with the tooth grooves below the rotating disk 14 .

[0042] In this embodiment, when the liquid level in the kettle structure is higher than the impeller, the float 15 drives the traction column 17 to slide upward, and the upper end of the traction column 17 is combined with the tooth groove below the turntable 14. At this time, when the transmission shaft 11 rotates, the turntable 14 rotates, which can drive the traction column 17 and the float 15 to rotate together, thereby driving the impeller to rotate; when the liquid level in the kettle structure is lower than the impeller, the upper end of the traction column 17 is separated from the tooth groove below the turntable 14, and the turntable 14 cannot drive the traction column 17, the float 15 and the impeller to rotate when it rotates.

[0043] As a further solution of the present invention, a latching tooth is formed on the upper end of the traction column 17, and the latching tooth and the tooth groove below the rotating disk 14 are both in the shape of a right triangle.

[0044] In this embodiment, when the rotating disk 14 rotates clockwise, the vertical section of the tooth groove below the rotating disk 14 pushes the traction column 17 to rotate, so that the traction column 17 will only be pushed in the horizontal direction and will not move downward when rotating;

[0045] If the turntable 14 rotates counterclockwise, the inclined cross-section of the tooth groove below the turntable 14 pushes the traction column 17 to rotate, and the thrust received is an oblique downward thrust, which cannot ensure that the turntable 14 can completely drive the traction column 17 to rotate synchronously; therefore, when the external power device is working, it drives the transmission shaft 11 to rotate clockwise.

[0046] As a further solution of the utility model, the rotating sleeve 16 is sleeved on the transmission shaft 11, and the transmission shaft 11 is rotatably connected with the rotating sleeve 16, and a slide groove 18 is provided on the rotating sleeve 16, and the traction column 17 is slidably connected with the rotating sleeve 16 through the slide groove 18, and the traction column 17 keeps sliding with the slide groove 18;

[0047] When the traction column 17 rotates, the traction column 17 pushes the rotating sleeve 16 to rotate.

[0048] In this embodiment, when the liquid level is higher than the impeller at the current height, the float bag 15 will drive the traction column 17 to float up, and the traction column 17 will engage with the tooth groove below the turntable 14. At this time, the rotation of the turntable 14 will drive the traction column 17 to rotate, and because the traction column 17 maintains a sliding fit with the slide groove 18, the traction column 17 will push the rotating sleeve 16 to rotate together.

[0049] As a further solution of the present invention, grooves are provided on the inner wall of the rotating sleeve 16 and the outer wall of the transmission shaft 11, and rotating balls 19 are provided rollingly in the grooves.

[0050] In this embodiment, the rotating ball 19 can rotatably connect the rotating sleeve 16 to the transmission shaft 11, so that the rotating sleeve 16 cannot slide in the vertical direction; because the rotating sleeve 16 and the transmission shaft 11 are connected through the rotating ball 19 and the recessed channel, and are not fixedly connected, the rotating sleeve 16 will not rotate together with the transmission shaft 11 after the upper end of the traction column 17 is separated from the tooth groove below the turntable 14.

[0051] As a further solution of the utility model, a fixing component for limiting the circumferential runout of the transmission shaft 11 is provided at the lower part of the transmission shaft 11, and the fixing component includes a fixing bracket 12 fixedly connected to the inner wall of the kettle structure, and the fixing bracket 12 is socket-fitted with the transmission shaft 11, and a groove 21 is provided on the inner wall of the fixing bracket 12, and a limiting ball 20 is rollingly embedded in the groove 21, and the fixing bracket 12 and the transmission shaft 11 are socket-connected through a circle of limiting balls 20.

[0052] In this embodiment, if a fixing component is not provided, when the transmission shaft 11 rotates, circular runout will occur because the lower end of the transmission shaft 11 is not constrained; in the present application, the circumferential runout of the transmission shaft 11 is limited by the fixing bracket 12, and because of the groove 21 and the limiting ball 20, the rotation of the transmission shaft 11 will not be affected by greater friction; in addition, under the action of the limiting ball 20, the transmission shaft 11 can be more conveniently socketed when assembled to the center of the fixing bracket 12.

[0053] As a further solution of the utility model, the kettle body structure includes a kettle body 1, a kettle cover 2 installed above the kettle body 1, a plurality of cylinders 4 fixedly installed on the outer wall of the kettle body 1, a feeding hole 6 and an inspection port 7 fixedly installed on the outer wall of the kettle body 1, and a telescopic rod 5 connected to the cylinder 4 at one end, and the other end of the telescopic rod 5 is fixedly connected to the kettle cover 2.

[0054] In this embodiment, when it is necessary to open the kettle cover 2 for inspection and maintenance, the cylinder 4 can be operated, the telescopic rod 5 can be raised, and the kettle cover 2 can be lifted to open the kettle body structure; when the kettle body structure is working, raw materials can be added from the feeding hole 6, and simple maintenance and inspection and removal of crystallized products can be carried out through the inspection manhole 8.

[0055] As a further solution of the utility model, a drain valve 10 is installed at the bottom of the kettle body 1, and a base 9 is fixedly installed at the bottom of the kettle body 1. A plurality of bottom brackets 7 are circumferentially installed on the base 9. The bottom brackets 7 pass through the base 9, and the bottom brackets 7 are fixedly installed on the outer wall of the kettle body 1;

[0056] A hole for the drain valve 10 to pass through is opened at the center of the base 9.

[0057] In this embodiment, the plurality of bottom brackets can maintain the stable state of the kettle body structure during operation. The kettle body 1 needs to be cleaned after use. At this time, the drain valve 10 is opened, and the clean water in the kettle body structure can be discharged using the drain valve 10 at the bottom. When the kettle body structure is in use, the drain valve 10 can be closed to prevent the solution in the kettle body structure from flowing out.

[0058] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
