Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a silver powder drying device. Background Technology

[0002] In the silver electrolysis process of precious metal smelting, the silver powder deposited on the cathode plate contains a large amount of moisture after washing. It must be dried to reach a dry state before it can be further processed.

[0003] In existing technologies, a conveying screw is generally used for repeated drying operations, but this results in uneven drying of silver powder. For example, application number CN201720507735.2 describes a rapid drying device for silver powder that uses a conveying screw to transport silver powder for repeated drying. However, the device has the following drawback: a small amount of silver powder adheres and accumulates directly on the support or distribution plate, preventing it from being transported to the next cycle, thus causing uneven drying and insufficient drying of the silver powder.

[0037] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:

[0038] Figure 1-5 This invention discloses a silver powder drying device, comprising: a drying tank 1, with an inlet 11 and an outlet 12 respectively provided at its upper and lower ends; a support frame 2, which is detachably connected to the outside of the drying tank 1; and further comprising:

[0039] The drying tank 1 is composed of an upper semi-cylinder and a lower semi-circular frustum, and a heating mesh 3 is fixedly connected to the inner wall of the upper semi-cylinder.

[0040] The material shaking component 4 is movably connected inside the drying tank 1 and installed relative to the feed inlet 11;

[0041] Sprinkling component 5 is installed on the central axis of drying tank 1, and the length of sprinkler component 5 is adapted to the vertical length of the inner wall of drying tank 1. One end of sprinkler component 5 is connected to the output end of drive motor 6, and the upper outlet position is higher than the shaking component 4.

[0042] Working principle:

[0043] The operator adds silver powder through the feed inlet 11 at the top of the drying tank 1. The silver powder falls directly onto the shaking component 4. The shaking component 4 breaks up the clumps of silver powder by reciprocating small amplitudes to prevent accumulation.

[0044] The dispersed silver powder falls into the heating mesh 3 under the action of gravity to achieve drying. The drive motor 6 is started by the external power supply, which activates the spreading component 5 to lift the silver powder above the shaking component 4 to complete the spreading. The silver powder then falls back into the heating mesh 3 through the shaking component 4. This cycle of "spreading-shaking-falling" is repeated to achieve uniform and thorough drying until the silver powder drying operation is completed. The operator then opens the discharge port 12 to collect the silver powder.

[0045] In actual use, the support frame 2 is detachably connected to the outside of the drying tank 1, such as... Figure 1The upper half of the support frame 2 has a diameter larger than that of the upper cylinder, and the lower half is adapted to the lower truncated cone. The drying tank 1 can be placed directly on the support frame 2, and the contact parts of the two can be connected and fixed with screws as needed.

[0046] This device prevents silver powder from clumping through the shaking component 4 and forms a closed-loop cycle of "sprinkling-falling-sprinkling" under the spraying component 5, so that the silver powder forms a three-dimensional circulating motion in the device, ensuring that the silver powder can be fully and evenly heated, effectively improving the drying quality and efficiency.

[0047] As described above, the top edge of the drying tank 1 is provided with a protruding annular movable groove 13 with two ears;

[0048] The structure of the material shaking component 4 includes:

[0049] The shell 41 has a movable ring 42 with two ears at its upper end, and the size of the movable ring 42 is smaller than the annular movable groove 13, so as to be movably connected to the upper half of the drying tank 1.

[0050] The conical perforated plate 43 has a shape that is narrow at the top and wide at the bottom, and a notch 44 is provided in the middle of the conical perforated plate 43. The conical perforated plate 43 is fixedly installed at the bottom of the housing 41.

[0051] The delivery pipe 45 is installed at the notch 44, and the size of the spraying component 5 is smaller than that of the delivery pipe 45 to achieve the sleeve installation;

[0052] The vibration motor 8 is mounted on the drying tank 1, and its output end passes through the drying tank 1 and contacts the outside of the shell 41 via the connecting rod 81.

[0053] A heating zone 46 is formed between the lower part of the conical perforator 43, the outer wall of the conveying pipe 45, and the heating mesh 3.

[0054] Working principle:

[0055] Silver powder falls into the housing 41 of the shaking assembly 4 through the feed inlet 11. The vibration motor 8 is started by an external power supply. The vibration motor 8 transmits the vibration to the outside of the housing 41 through the connecting rod 81. At this time, the movable ring 42 at the upper end of the housing 41 cooperates with the annular movable groove 13 on the edge of the top surface of the drying tank 1, allowing the housing 41 to vibrate slightly within a certain range, thereby driving the internal conical sluice plate 43 to vibrate synchronously.

[0056] Silver powder falls through the perforated gaps of the conical stencil 43 into the heating zone 46, where it is dried.

[0057] Among them, ① during the process of silver powder rising through the spraying component 5, since the conveying pipe 45 is larger than the size of the spraying component 5, the vibration of the housing 41 will not affect the transmission operation of the spraying component 5.

[0058] Meanwhile, if silver powder adheres to the inner wall of the conveying pipe 45, the vibration of the housing 41 will cause the silver powder to fall off and re-enter the conveying path of the spraying component 5 to continue to be conveyed upward, thus avoiding silver powder residue.

[0059] ② The conical sieve plate 43 is narrow at the top and wide at the bottom, so that the silver powder is scattered in all directions and will not fall back into the conveying tube 45 from the opening 44.

[0060] ③ In actual use, to increase the service life of the device, a layer of friction-resistant and impact-resistant material (such as rubber) can be added at the contact point between the movable ring 42 and the annular movable groove 13.

[0061] ④ In actual use, the vibration motor 8 can be a commercially available product or a motor product commonly used in the prior art (such as application number: CN202223065648.6, etc.).

[0062] As described above, the structure of the spraying component 5 includes:

[0063] The rotating shaft 51 has one end connected to the output end of the drive motor 6 and is installed inside the drying tank 1 via a bearing;

[0064] Screw blade 52 is mounted on the rotating shaft, and the transverse diameter of screw blade 52 is smaller than that of conveying pipe 45.

[0065] Working principle:

[0066] After the drive motor 6 is started by the external power supply, the output end of the drive motor 6 drives the rotating shaft 51 to rotate at high speed, and the auger blades 52 installed on the rotating shaft 51 rotate synchronously.

[0067] When the silver powder is fed into the bottom of the auger blade 52, the centrifugal force and spiral upward thrust generated by the rotation of the auger blade 52 will transport the silver powder upward along the inner wall of the conveying pipe 45, and finally sprinkle it onto the shaking assembly 4, and enter the next round of cycle drying.

[0068] Among them, ① the transverse diameter of the auger blade 52 is smaller than that of the conveying pipe 45, so that the vibration of the material shaking component 4 will not affect the operation of the spreading component 5.

[0069] ② The rotating shaft 51 rotates stably inside the drying tank 1 via bearings.

[0070] In the above scheme, the lower end of the auger blade 52 protrudes from the conveying pipe 45 and the blade radius gradually increases until the edges on both sides of the bottom end approach the inner wall of the drying tank 1.

[0071] The upper end of the auger blade 52 protrudes from the conveying tube 45, and the blade radius gradually increases until the diameter of the highest end is greater than the inner diameter of the conveying tube 45.

[0072] Working principle:

[0073] As the silver powder falls, the lower end of the auger blade 52 protrudes from the conveying pipe 45, and the blade radius gradually increases, allowing the silver powder to fall directly onto the auger blade 52 instead of accumulating at the bottom of the drying tank 1.

[0074] As the upper end of the auger blade 52 protrudes from the conveying pipe 45 and the blade radius gradually increases, the silver powder is transported upwards and then sprinkled to both sides onto the shaking component 4 at the port of the conveying pipe 45, without falling back.

[0075] After the drying process is completed, the auger blades 52 can be rotated in the opposite direction to allow the silver powder to continue falling to the discharge port 12 for recycling.

[0076] As described above, the top of the drying tank 1 is equipped with an exhaust moisture absorption tank 9, and a filter screen 91 is provided at the position where the exhaust moisture absorption tank 9 communicates with the inner end face.

[0077] Working principle:

[0078] During the drying process of silver powder inside the drying tank 1, moisture evaporates to form a hot and humid airflow, which flows towards the top exhaust and moisture absorption tank 9, and the moisture is adsorbed by the internal silica gel or molecular sieve.

[0079] Among them, the filter screen 91 prevents silver powder from being discharged with the air and polluting the environment, and the silver powder falls back onto the shaking component 4.

[0080] In the above scheme, both the feed inlet 11 and the discharge outlet 12 are equipped with material covers, and the feed inlet 11 is funnel-shaped. The material cover can meet the requirements of the drying process for airtightness and moisture prevention. The funnel shape of the feed inlet 11 can speed up the efficiency of each material discharge.

[0081] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
