Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystal drying technology, and in particular to a crystal particle drying device. Background Technology
[0002] Evaporation crystallization is a common method for separating and purifying solid substances from solutions. Considering factors such as product purity and crystallinity, the crystals are usually separated by centrifugation before sufficient crystals have precipitated from the solution. However, centrifugation inevitably results in less water being separated from the crystals, leading to an excessively high water content in the product.
[0003] If this part of the crystal is further dried by heating to reduce the water content of the crystal, it may lead to the loss of some water of crystallization or changes in the crystal morphology. In severe cases, it may even cause thermal decomposition, all of which will result in a decline in product quality. Utility Model Content

[0029] This utility model proposes a crystal particle drying device 1000.
[0030] Please see Figure 1 , Figure 2 as well as Figure 3 In one embodiment of this utility model, the crystal particle drying equipment 1000 includes a housing 1 and a support plate 2. The housing 1 forms an inner cavity 1a and an air inlet channel 1d. The inner cavity 1a includes a drying cavity 1a1 and a collecting cavity 1a2. The drying cavity 1a1 is connected to the collecting cavity 1a2 and is located above the collecting cavity 1a2. The air inlet channel 1d is connected to the drying cavity 1a1. A feed inlet 1b is formed on the cavity wall of the drying cavity 1a1. The support plate 2 is connected to the housing 1 and is located inside the drying cavity 1a1. The support plate 2 is located below the feed inlet 1b. The air inlet channel 1d is used to blow compressed air onto the surface of the support plate 2.
[0031] In the technical solution of this utility model, the crystal particles enter the drying chamber 1a1 through the feed port 1b and fall onto the support plate 2; compressed air is introduced into the air inlet channel 1d and blown onto the crystal particles falling onto the support plate 2, thereby accelerating the air flow speed on the surface of the crystal particles and thus accelerating the evaporation of moisture on the crystal particles; the crystal particles can be dried without heating them, so as not to cause a decline in the quality of the crystal products.
[0032] Please see Figure 3 and Figure 4 In one embodiment of this invention, the end of the support plate 2 closest to the air intake channel 1d is positioned higher than the end furthest from the air intake channel 1d. When crystal particles are placed on an inclined surface, the moisture on the crystal particles adheres to the inclined surface; the more moisture adheres to the crystal particles, the stronger the adhesion between them and the inclined surface, and the slower the crystal particles roll down the inclined surface. The support plate 2 has a certain degree of inclination, allowing the user to observe the rolling speed of the crystal particles on the support plate 2 to determine whether the moisture content of the crystal particles exceeds the standard, and decide whether to blow compressed air into the air intake channel 1d to dry the crystal particles, thereby reducing energy waste. The inclined design of the support plate 2 facilitates the flow of the dried crystal particles into the collection chamber 1a2 for easy collection.
[0033] Please see Figure 3 and Figure 4 In one embodiment of this utility model, the angle between the support plate 2 and the horizontal plane is defined as α, and the angle between the central axis of the air intake channel 1d and the horizontal plane is defined as β; wherein, α≤β. By controlling the values of α and β, the compressed air introduced into the air intake channel 1d can be directly blown onto the surface of the support plate 2, optimizing the dynamic characteristics of the airflow and improving the drying efficiency.
[0034] It should be noted that α can be any angle between 0° and 90°; furthermore, 3°≤α≤5°. In one embodiment of this utility model, α=5°. When α=5°, the rolling speed of the crystal particles on the support plate 2 is easy for the user to observe, thereby enabling the user to make a better judgment on whether to blow in compressed air; at the same time, when α=5°, it can ensure that the rolling speed of the crystal particles on the support plate 2 is appropriate, neither causing the rolling speed to be too fast due to an excessively large tilt angle, resulting in the crystal particles falling into the collection chamber 1a2 before being completely dried, nor causing the crystal particles to fail to roll due to an excessively small tilt angle.
[0035] Please see Figure 1 , Figure 2 as well as Figure 3 In one embodiment of this utility model, the housing 1 also has an air inlet 1e, which connects to the drying chamber 1a1 and is positioned below the end of the support plate 2 away from the air intake channel 1d. Air is introduced into the air inlet 1e, which can perform a secondary drying process on the crystal particles before they fall into the collection chamber 1a2, thereby more thoroughly removing moisture from the surface of the crystal particles and improving the drying quality.
[0036] Please see Figure 2 and Figure 3 In one embodiment of this utility model, the housing 1 has two air inlets 1e, both of which are located on the side of the support plate 2 away from the air inlet channel, and are respectively located on opposite sides of the housing 1 along the length direction of the support plate 2. The design of two air inlets 1e can ensure more uniform airflow in the drying chamber 1a1, thereby enabling drying treatment on both sides of the crystal particles; by setting air inlets 1e on opposite sides, the drying speed can be accelerated and the drying efficiency can be improved.
[0037] Please see Figure 2 and Figure 3 In one embodiment of this invention, a discharge port 1c is formed on the wall of the collecting cavity 1a2 at the end away from the drying cavity 1a1. The collecting cavity 1a2 gradually narrows from the end near the drying cavity 1a1 to the end away from the drying cavity 1a1. The gradually narrowing design of the collecting cavity 1a2 helps guide the dried crystal particles towards the discharge port 1c, reducing the accumulation and scattering of crystal particles in the collecting cavity 1a2. The discharge port 1c allows the dried crystal particles to be easily removed from the collecting cavity 1a2, improving the convenience of collection.
[0038] Please see Figure 1 and Figure 3In one embodiment of this utility model, an observation hole 1f is formed on the top of the housing 1, which is connected to the drying chamber 1a1, allowing the user to observe the crystal particles on the support plate 2. The user can quickly check the dryness of the crystal particles through the observation hole 1f without opening the housing 1 or using other testing equipment, making it convenient to use.
[0039] Please see Figure 1 In one embodiment of this invention, the observation hole 1f is rectangular in shape. The rectangular observation hole 1f is adapted to the shape of the support plate 2, which can maximize the observation area, allowing the user to observe more crystal particles on the support plate 2 and improve observation efficiency.
[0040] Please see Figure 3 and Figure 4 In one embodiment of this utility model, the crystal particle drying equipment 1000 further includes a support plate 3, one end of which is disposed on the housing 1, and the other end of which is disposed away from the housing 1 on the bearing plate 2; the support plate 3 is used to support the bearing plate 2. The use of the support plate 3 enhances the structural stability of the bearing plate 2 and reduces deformation caused by the weight of the bearing plate 2 itself or the weight of the crystal particles.
[0041] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
