DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0029] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 3 As shown, this example provides a moisture separation device, which includes a first cavity 1, a second cavity 2 that can be communicated with the first cavity 1, a stirring mechanism 3, a first heat exchange mechanism, a second heat exchange mechanism, and a first water absorption component 6 and a second water absorption component that can absorb and release moisture; part of the stirring mechanism 3 extends into the first cavity 1, the first heat exchange mechanism is arranged on the first cavity 1 and is used to increase or decrease the temperature inside the first cavity 1, and the second heat exchange mechanism is arranged on the second cavity 2 and is used to increase or decrease the temperature inside the second cavity 2; the first water absorption component 6 is arranged at the bottom of the second cavity 2, the second cavity 2 is located above the first cavity 1 and is detachably connected to the first cavity 1 through the first water absorption component 6, the second water absorption component is arranged inside the second cavity 2 and is located above the first water absorption component 6, a feed port 11 is arranged on the first cavity 1, and an air extraction port 21 is arranged at the upper part of the second cavity 2.

[0031] In this example, the stirring mechanism 3 includes a stirring shaft 31 extending from the lower part of the first cavity 1 into the interior, a stirring blade 32 located in the first cavity 1 and arranged on the stirring shaft 31, and a driving component 33 for driving the stirring shaft 31 to rotate. The stirring shaft 31 in this example extends from the lower part of the first cavity 1 into the interior. In order to further increase the sealing performance, a sealing member can be added to the corresponding part of the stirring shaft 31 passing through the first cavity 1 to prevent the internal material from leaking out. The driving component 33 can be a motor, etc.; the stirring blade 32 includes a sleeve 321 that can be sleeved on the stirring shaft 31 and a plurality of blades 322 respectively arranged on the sleeve 321. The planes where at least two of the aforementioned plurality of blades 322 are located intersect. Such a setting can disturb the internal material with multiple surfaces in different directions as much as possible, realize the flow collision of the material in multiple directions, and greatly improve the heat and mass transfer efficiency. Further, see Figure 3As shown, the blade 322 includes a first sub-blade 3221 connected to the shaft sleeve 321, a second sub-blade 3222 connected to the first sub-blade 3221, and a connecting piece 3223. The planes where the first sub-blade 3221 and the second sub-blade 3222 are located intersect, and the first sub-blade 3221 and the second sub-blade 3222 are detachably connected through the connecting piece 3223. In this example, the blade 322 is uniquely designed so that when a single blade 322 rotates and disturbs the material, it can further bring more disturbance directions, exert forces on the material from more directions, improve contact efficiency, and achieve rapid heat and mass transfer; preferably, in this example, a through hole (not shown) can also be provided on the blade 322, for example, through holes with different extension directions can be provided on the first sub-blade 3221 and the second sub-blade 3222 respectively, and the existence of the through hole can cause the material passing through the through hole to change its speed and direction of movement during movement, etc., which once again improves the mass and heat transfer efficiency of the material, thereby greatly improving the uniformity of heating the material and ensuring an excellent dewatering effect.

[0032] In this example, the stirring blades 32 have a plurality of blades extending along the axis of the stirring shaft 31. Figure 1 and Figure 2 As shown, the stirring blades 32 have two vertically distributed and parallel to each other, one stirring blade 32 is set at the top of the stirring shaft 31, and the other is set at the upper middle part of the stirring shaft 31. Preferably, the two stirring blades 32 are in the middle of the first cavity 1.

[0033] The first heat exchange mechanism includes a first jacket 41 covering the outer wall of the first cavity 1 and a first supply assembly for supplying heat exchange fluid into the first jacket 41; the second heat exchange mechanism includes a second jacket 51 covering the outer wall of the second cavity 2 and a second supply assembly for supplying heat exchange fluid into the second jacket 51. When the temperature needs to be increased, the heat exchange fluid can be high-temperature steam, high-temperature hot oil, etc. When the temperature needs to be lowered, cooling water, chilled water, etc. can be used. In general, the water removal device in this example does not need to be cooled. Of course, it can be cooled when necessary. See Figure 1 and Figure 2 As shown, the first jacket 41 is provided with two first jacket inlets and outlets 42, and the second jacket 51 is provided with two second jacket inlets and outlets 52. In actual use, one of them is used as an inlet and the other as an outlet, and the heat exchange fluid can be introduced by pumping.

[0034] In this example, a discharge port 12 is also provided on the first cavity 1, the feed port 11 is provided at the upper part of the first cavity 1, and the discharge port 12 is provided at the bottom of the first cavity 1. Feeding from the upper part is conducive to the rapid escape of moisture in the material after rapid heating. The discharge port 12 at the lower part can facilitate discharge and emptying of the material after the moisture in the material is discharged as much as possible.

[0035] In this example, the first water absorption component 6 includes a metal grid 61, cotton 62 and a metal microporous mesh 63 arranged in sequence from bottom to top. The metal grid 61 serves as a limiter for clamping the cotton 62 and a support for the cotton 62, the metal microporous mesh 63, etc. The metal grid 61 and the metal microporous mesh 63 both have pores that allow air flow to pass smoothly. Furthermore, the second water absorption component includes a dehydrating filler 71 supported on the metal microporous mesh 63, and the dehydrating filler 71 is filled in the interior of the second cavity 2. The dehydrating filler 71 acts as the main water absorption material, which basically fills the interior of the second cavity 2 completely, so that the water vapor flowing upward must be adsorbed by the dehydrating filler 71 and then discharged from the exhaust port 21. In this way, the cotton 62 and the dehydrating filler 71 both play an auxiliary role. When the exhaust port 21 is not enough to extract all the water vapor generated in a short time, the excess water vapor can be absorbed by them to avoid backflow into the material inside the lower first cavity 1. At a later stage, the cotton 62 and the dehydrating filler 71 can be heated by targeted heating to evaporate and extract the adsorbed water for recycling.

[0036] Specifically, the water-removing filler 71 can be molecular sieve, silica gel, super absorbent resin, etc.

[0037] In this example, the moisture separation device also includes a locking assembly, which includes a first boss 81 formed on the upper part of the first cavity 1, a second boss 82 formed on the bottom of the second cavity 2, and a locking pin (not shown). A first locking hole is formed on the first boss 81, and a second locking hole is formed on the second boss 82. The locking pin can be inserted into the first locking hole and the second locking hole respectively. The locking pin can be a locking rod or a bolt, which is then locked with a nut. Preferably, when locking is achieved, a sealing gasket is added between the two bosses to achieve better sealing. In other embodiments, the locking pin can be replaced with a clamp or other equipment to clamp and lock the two bosses from the outside.

[0038] In this example, a first temperature sensor mounting port 13 may be further provided on the first cavity 1 for mounting a first temperature sensor, so as to facilitate monitoring the temperature inside the first cavity 1 so as to adjust the heating temperature, for example, the temperature or flow rate or flow rate of the heat exchange fluid may be increased to increase the heat supply per unit time; similarly, a second temperature sensor mounting port 22 may be further provided on the second cavity 2 for mounting a second temperature sensor, so as to facilitate monitoring the temperature inside the second cavity 2 so as to adjust the heating temperature, for example, the temperature or flow rate or flow rate of the heat exchange fluid may be increased to increase the heat supply per unit time.

[0039] In this example, a plurality of ears 9 may be provided on the first cavity 1, which may be used to fix the first cavity 1, and further fix the entire moisture separation device.

[0040] In this example, the moisture separation device further includes a vacuum pumping mechanism connected to the air suction port 21 or other mechanisms capable of extracting internal water vapor, which is not specifically limited here.

[0041] In summary, based on the problems of the existing devices used for dehydrating polyhydroxy compounds, such as high price, slow dehydration speed, incomplete dehydration, etc., the utility model innovatively provides an improved moisture separation device. The separation device adopts a detachably connected first cavity and a second cavity, and a stirring mechanism is arranged on the first cavity, which can maximize the disturbance of the mixed solution passed into the interior, so that it can quickly realize heat exchange under the action of the first heat exchange mechanism, so that the temperature of various parts inside is quickly uniformed, which is conducive to the rapid heating and vaporization of moisture; the detachable connection method can separate the two cavities before adding materials, so that the materials can be quickly added from the top of the first cavity at one time, which greatly saves the adding time. At the same time, the utility model detachably connects the first cavity and the second cavity through the first water absorption component, simplifies the mechanism, reduces the space occupied, and is easy to install. Each component does not need to be greatly cut or modified when some components need to be replaced; in addition, the vaporized water vapor is extracted from the air suction port of the second cavity, and the excess water or water that cannot be extracted in time or may remain on the inner wall can be absorbed by the first water absorption component and the second water absorption component respectively to avoid falling back into the material in the first cavity, thereby further ensuring the thoroughness of water separation. In particular, the second heat exchange mechanism can further provide heat. For example, when the water separation of the material in the first cavity reaches the expected value, the first water absorption component and the second water absorption component are heated while the material is discharged, and the water absorbed by them is vaporized and discharged from the air suction port, so that they can continue to play the role of water absorption in the future, ensuring sufficient adsorption capacity, which is beneficial to the adsorption of water in subsequent batches of materials to avoid falling back, realizing reuse and good recycling performance.
