Description

Technical Field

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

[0002] Potassium gold cyanide is a white crystalline solid, a complex salt formed by gold ions and cyanide ions. It is soluble in water, slightly soluble in ethanol, and insoluble in ether. It is hygroscopic and highly toxic. Potassium gold cyanide is a highly toxic chemical, with a toxicity essentially the same as potassium cyanide. The lethal dose is approximately 0.1 grams. Preparation: Pure gold reacts with aqua regia, is filtered and concentrated, then concentrated hydrochloric acid is added to remove nitrogen oxides. It is then reacted with potassium cyanide, and finally crystallized to obtain the finished product. Potassium gold cyanide is an important electroplating chemical raw material, a major gold plating material for integrated circuit boards or handicrafts, mainly used in electroplating of electronic products, as well as in analytical reagents and the pharmaceutical industry. It can be produced by the reaction of potassium cyanide and gold chloride.

[0003] For example, an existing patent (publication number: CN113368982B) discloses a dosing device for the production of potassium gold cyanide. By starting a first motor to rotate, the first motor drives a second rotating rod to rotate, and the second rotating rod drives a tug to rotate. The tug causes the pulverized medicine on the screening plate to rotate. While rotating, the powdered medicine falls into the dosing tank through the holes in the screening plate, and the granular medicine enters the other side of the screening plate. The granules on the other side of the screening plate can be removed through the upper opening of the outer wall of the dosing tank.

[0004] However, the above-designed dosing device still has some drawbacks in actual use: Although the scheme is equipped with a sieve plate to screen out the unground medicine, the screening method still requires manual removal from the upper opening of the outer wall of the dosing tank and put it back into the grinding mechanism for grinding. This process increases the number of manual operation steps and labor intensity. Frequent medicine removal and delivery operations will interrupt the normal operation of the dosing device, resulting in a significant reduction in overall production efficiency and making it impossible to achieve continuous and efficient production operations.

[0005] To address these issues, we designed a dosing device for potassium gold cyanide production. Utility Model Content

[0006] The purpose of this invention is to provide a dosing device for the production of potassium gold cyanide, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a dosing device for the production of potassium gold cyanide, including a dosing tank. The dosing tank has, from top to bottom, a feed inlet, a crushing mechanism, and a stirring mechanism. The feed inlet is located at the top of the dosing tank. The crushing mechanism includes an arc-shaped bottom plate disposed inside the dosing tank. A rotating shaft is rotatably connected inside the crushing mechanism. Connecting plates are fixedly connected to both the front and rear sides of the rotating shaft. A connecting shaft is fixedly connected between the ends of the two connecting plates away from the rotating shaft. A crushing roller is rotatably connected to the connecting shaft. The crushing roller matches the arc-shaped bottom plate. Several sieve holes are opened at the bottom of the arc-shaped bottom plate, and connecting plates are fixedly connected to both ends of the top of the arc-shaped bottom plate.

[0008] Furthermore, a first motor is fixedly connected to the outside of the dosing tank, and the rotating end of the first motor is fixedly connected to the rotating shaft.

[0009] Furthermore, the dosing tank is also equipped with a vibration mechanism, which includes a sliding cavity. The sliding cavity is opened on both inner walls of the dosing tank. The connecting plate is slidably connected in the sliding cavity. The bottom end of the sliding cavity is provided with an installation groove. A telescopic rod is fixedly connected inside the installation groove. A spring is sleeved on the telescopic rod. The other end of the telescopic rod is fixedly connected to the bottom end of the connecting plate.

[0010] Furthermore, there are multiple telescopic rods and springs, and these multiple telescopic rods and springs are evenly installed in the mounting groove.

[0011] Furthermore, the stirring mechanism includes a stirring shaft, which is rotatably connected inside the stirring mechanism. Multiple stirring blades are fixedly connected to the outer surface of the stirring shaft. A discharge port is opened at the bottom end of the stirring mechanism, and a baffle is rotatably connected to the discharge port.

[0012] Furthermore, a second motor is fixedly connected to the outside of the dosing tank, and the rotating end of the second motor is fixedly connected to the stirring shaft.

[0013] Furthermore, a sealing cap is snapped onto the top of the feed inlet, and a sealing ring is provided inside the sealing cap.

[0014] Furthermore, the bottom of the dosing tank is fixedly connected to four support legs, which are symmetrically arranged on the left and right sides of the bottom of the dosing tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, a uniquely designed pulverizing mechanism first uses pulverizing rollers on an arc-shaped base plate to effectively pulverize the raw pharmaceutical materials. Larger pharmaceutical materials are pulverized into smaller particles that can fall into the mixing mechanism through sieve holes. Smaller pharmaceutical materials can directly enter the mixing mechanism through the sieve holes. Subsequently, the mixing blades thoroughly mix the pharmaceutical materials. This process achieves efficient connection between pulverization and mixing, effectively avoiding problems such as insufficient pulverization and uneven mixing caused by excessively large pharmaceutical particles. It greatly improves the quality and efficiency of pharmaceutical processing in the production of potassium gold cyanide, ensuring the stability of product quality. Moreover, the various links of the device are compactly designed and have good synergy, eliminating the need for frequent start-ups and shutdowns of different equipment for material transfer and secondary processing, thus reducing unnecessary energy consumption.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 2 and Figure 4This utility model provides a technical solution: a dosing device for the production of potassium gold cyanide, including a dosing tank 1. The dosing tank 1 is provided with a feed inlet 2, a crushing mechanism 3 and a stirring mechanism 4 arranged sequentially from top to bottom. The feed inlet 2 is located at the top of the dosing tank 1. The crushing mechanism 3 includes an arc-shaped bottom plate 31, which is set inside the dosing tank 1. A rotating shaft 32 is rotatably connected inside the crushing mechanism 3. Connecting plates 33 are fixedly connected to both the front and rear sides of the rotating shaft 32. A connecting shaft 34 is fixedly connected between the ends of the two connecting plates 33 away from the rotating shaft 32. A crushing roller 35 is rotatably connected to the outside of the connecting shaft 34. The crushing roller 35 matches the arc-shaped bottom plate 31. Several sieve holes 36 are opened at the bottom of the arc-shaped bottom plate 31. Connecting plates 37 are fixedly connected to both ends of the top of the arc-shaped bottom plate 31. A first motor 38 is fixedly connected to the outside of the dosing tank 1. The rotating end of the first motor 38 is fixedly connected to the rotating shaft 32.

[0024] In practice, the raw materials required for the production of potassium gold cyanide are added through the feed inlet 2. The raw materials fall onto the arc-shaped bottom plate 31. Smaller materials can pass directly through the sieve holes 36 of the arc-shaped bottom plate 31, while larger materials will remain on the arc-shaped bottom plate 31. The first motor 38 is started, which drives the rotating shaft 32 and the connecting plate 33 to rotate, thereby causing the crushing roller 35 on the connecting shaft 34 to rotate inside the arc-shaped bottom plate 31. Due to the special shape of the arc-shaped bottom plate 31, the crushing roller 35 can effectively crush the materials during rotation.

[0025] See Figure 2 and Figure 3 The dosing tank 1 is also equipped with a vibration mechanism, which includes a sliding cavity 11. The sliding cavity 11 is opened on both sides of the inner wall of the dosing tank 1. The connecting plate 37 is slidably connected in the sliding cavity 11. The bottom end of the sliding cavity 11 is provided with an installation groove 12. The installation groove 12 is fixedly connected to the inside of the installation groove 12. The extension rod 13 is sleeved with a spring 14. The other end of the extension rod 13 is fixedly connected to the bottom end of the connecting plate 37.

[0026] In practice, during the crushing process, when the crushing roller 35 rotates onto the arc-shaped base plate 31, it will press the arc-shaped base plate 31 and the connecting plate 37 downwards. The connecting plate 37 in the sliding cavity 11 will cause the spring 14 and the telescopic rod 13 to compress downwards. When the crushing roller 35 rotates away from the arc-shaped base plate 31, the spring 14 and the telescopic rod 13 will rebound. The arc-shaped base plate 31 will vibrate under the repeated compression and rebound motion of the spring 14 and the telescopic rod 13. This vibration can promote the movement and dispersion of the medicine on the arc-shaped base plate 31, avoid the medicine from accumulating in one place and affecting the crushing effect, and at the same time help the medicine that has been crushed into smaller particles to fall through the sieve hole 36.

[0027] See Figure 3 There are multiple telescopic rods 13 and springs 14, and multiple telescopic rods 13 and springs 14 are evenly installed in the mounting groove 12.

[0028] In practice, during the vibration process, the uniform force on each telescopic rod 13 and spring 14 enables the arc-shaped base plate 31 to produce a stable and uniform vibration effect, avoiding vibration instability caused by uneven local force, thereby ensuring the movement and dispersion of medicine on the arc-shaped base plate 31, as well as the smoothness of the medicine falling through the sieve holes 36.

[0029] See Figure 2 and Figure 4 The stirring mechanism 4 includes a stirring shaft 41, which is rotatably connected inside the stirring mechanism 4. Multiple stirring blades 42 are fixedly connected to the outer surface of the stirring shaft 41. A discharge port is opened at the bottom of the stirring mechanism 4, and a baffle 43 is rotatably connected to the discharge port. A second motor 44 is fixedly connected to the outside of the dosing tank 1, and the rotating end of the second motor 44 is fixedly connected to the stirring shaft 41.

[0030] In practice, the medicine leaking out of the sieve hole 36 will enter the area where the stirring mechanism 4 is located under the action of gravity. At this time, the second motor 44 drives the stirring shaft 41 to rotate, and the stirring blades 42 on the stirring shaft 41 stir and mix the leaked medicine.

[0031] See Figure 1 A sealing cover 21 is snapped onto the top of the feed inlet 2, and a sealing ring is provided inside the sealing cover 21.

[0032] In practice, the sealing cap 21 and the sealing ring play a sealing role to prevent drug leakage or external impurities from entering the dosing tank 1 during the dosing process and when the dosing device is running, so as to affect the quality of the drug and the normal operation of the dosing device.

[0033] See Figure 1 The bottom of the dosing tank 1 is fixedly connected to four support legs 5, which are symmetrically arranged on the left and right sides of the bottom of the dosing tank 1.

[0034] In practice, the outriggers 5 support the dosing tank 1, raising it a certain height off the ground or operating platform. This facilitates material discharge operations and equipment maintenance from below the dosing tank 1, while ensuring the stability of the dosing tank 1 during operation.

[0035] Working principle: During use, the raw materials required for potassium gold cyanide production are added through the feed inlet 2. The raw materials fall onto the arc-shaped bottom plate 31. Smaller materials can pass directly through the sieve holes 36 of the arc-shaped bottom plate 31, while larger materials remain on the arc-shaped bottom plate 31. The first motor 38 is started, which drives the rotating shaft 32 and the connecting plate 33 to rotate, thereby causing the crushing roller 35 on the connecting shaft 34 to rotate within the arc-shaped bottom plate 31. Due to the special shape of the arc-shaped bottom plate 31, the crushing roller 35 can effectively crush the materials during rotation. During the crushing process, when the crushing roller 35 rotates onto the arc-shaped bottom plate 31, it will press the arc-shaped bottom plate 31 and the connecting plate 37 downward. The connecting plate 37 in the sliding cavity 11 will then compress the spring 14 and the telescopic rod 13 downward. When the crushing roller 35... When the device rotates away from the arc-shaped base plate 31, the spring 14 and the telescopic rod 13 will rebound. The arc-shaped base plate 31 will vibrate under the repeated compression and rebound motion of the spring 14 and the telescopic rod 13. This vibration can promote the movement and dispersion of the medicine on the arc-shaped base plate 31, avoid the medicine from accumulating in one place and affecting the pulverization effect, and at the same time help the medicine that has been pulverized into smaller particles to fall through the sieve hole 36. The medicine that leaks out of the sieve hole 36 will enter the area where the stirring mechanism 4 is located under the action of gravity. At this time, the second motor 44 drives the stirring shaft 41 to rotate. The stirring blade 42 on the stirring shaft 41 stirs and mixes the leaked medicine, further ensuring that the medicine is mixed evenly. After the medicine is mixed, the baffle 43 connected to the discharge port is opened, and the mixed medicine powder can be collected through the discharge port.
