[Prior art] The self-crystallization method includes, for example, an adiabatic cooling method, a direct cold-part method of injecting a refrigerant, an indirect cooling method using a water jacket or a heat exchanger, an evaporation concentration method, and a salting-out method. These crystallization methods are appropriately selected and used according to the characteristics of the crystal, the relationship between the pre- and post-processes, and the economy. ^ In addition, in the indirect cooling method, in order to avoid the shortcomings of "degradation of thermal conductivity and deterioration of operability due to the adhesion of crystals on the cooling surface", there is a supply of a new stock solution or a temporary heating of the cooling surface to adhere to the cooling surface. The method (intermittent type) and the method of scraping the crystals attached to the cooling surface with a scraping blade (so-called scraper) (scraping type). However, since the batch type indirect cooling method causes operational problems when the processing amount is large, a scraper type indirect cooling method is widely used in the present practice. The crystallization apparatus using this scraping type indirect cooling method is, for example, the apparatus shown in the first figure.

Driving devices such as motors. In this device, there is another problem that the driving device M is different from the driving device M (installed in 4 ° 10 °, because of the problem of crystal wear and fragmentation due to the inner rotation of the engine 1 and the south speed of the 03th rotation.

It also has a swirling flow suppression plate 207 that suppresses the rotation of the to-be-processed liquid p caused by the swirling flow: ', 206, and changes the direction of the jujube to the vertical flow (see, for example, Patent Document 1). ). This crystallization device 200 is very useful because it prevents the crystalline crushing treatment liquid from rotating. [Patent Document 1] Japanese Patent Publication No. 61-25402 (second figure) However, in recent years, In the future, we need to make the crystal grow bigger and micro: A crystallization device with fewer crystals is also expected to improve such a crystallization device. Of course, it is also considered that the method of increasing the rotation speed of the rotating blades to generate a %% flow will make the crystal grow larger. It is easy to produce crystals that are damaged or broken, so the advantages of this device are offset. Therefore, the main object of the present invention is to provide a 200407191 that prevents the crystals from abrasion or breakage, and can make the crystals grow larger and reduce the fineness.

In the three-axis direction, in the present embodiment, three pieces of the rotation / melon suppression plate 10 (hereinafter simply referred to as s, the side-by-side flow-suppression suppression plate 10) of the liquid to be treated are treated as well as the film. You page 5 A swirling flow suppressing plate η (which is simply referred to as an upper-side swirling flow suppressing plate 丨 丨 hereinafter) which extends in the direction of three axes of a circumferential wall and 3 pieces of processed liquid ρ in this embodiment. The circumferential wall 3 of the groove 6 has a main shape of [§] 铃 ο 上, and the lower end edge of the circumferential wall 3 is connected to the groove bottom 4, and the upper edge is connected to the groove top 5. The groove bottom 4 and the groove top I may be connected to the circumference The wall 3 is integrally formed, and can also be formed as a separate component from the circumferential wall 3. In this embodiment, the groove bottom 4 and the groove top 5 are both separate components from the circumferential wall 3. In addition, the knife is not in the groove The top 5 is provided with a liquid treatment port 15 and the bottom 4 is provided with two liquid discharge ports 丨 6, 丨 6. An outer water jacket 17 is provided on the peripheral wall 3. In this outer water jacket 17, the refrigerant is passed through the refrigerant supply and discharge port 17A, and the to-be-processed liquid ρ in the crystallizing tank 6 is indirectly cooled. The tube 7 is arranged coaxially with the circumferential wall 3 and separated from the groove bottom 4. The flow tube 7 is mounted on a shaft 19 through rod-shaped support spokes 18, 18, ... extending in the horizontal direction. The shaft 19 is It is arranged in the axial center portion of the circumferential wall 3 and extends in the up-down direction and is supported by the bearing 20.

在本發明中，與以往的把外側旋轉槳葉設在流通管的 :卜側中央部形式不$，之所以設在流通管的外側下端部， 疋為了主動地向上吸引與旋轉流抑制板接觸的被處理液。 即、，通過與旋轉流抑制板的接觸，截住使循環速度減低了 的！處理液，並通過實現循環速度的恢復，以維持合適的 \ :々果被處理液以正確的規則循環，則除了有效地促 進u B曰成長的效果外，還可以使析晶槽内的過飽和度均勻 並防止過飽和度局部過高，所以阻止了微結晶的產生。 ^在本只施例中，在流通管7的内側下端，還設有内側 ^轉木葉12。對内側旋轉槳葉i 2的設置方法沒有特殊的限 定。例如’如本實施例所示，可以是分別把其基端部安裝 在軸19上、把其前端部安裝在流通管7的内壁面上的形式 一或把其基端部安裝在軸19上、而其前端部不安裝在流通 I 7的内壁面上的形式。但是，若是基端部及前端部都被 女農的形式（前者的形式），則内側旋轉槳葉12，也可以 11 200407191 具有與上述的支撐輻條18、18".同樣的功能。In the present invention, the outer rotary blade is provided in the circulation tube in the conventional: the central portion of the side is not in the form, and it is provided in the outer lower end portion of the circulation tube, in order to actively attract upward contact with the swirling flow suppression plate Of the treated liquid. That is, by contact with the swirling flow suppression plate, the circulation speed is reduced due to interception! Treatment liquid, and by achieving the recovery of the circulation speed, to maintain the proper circulation of the treated fruit liquid with the correct rules, in addition to effectively promoting the growth effect of u, the supersaturation in the crystallization tank can also be made. The degree of uniformity and the prevention of local oversaturation are too high, so the generation of microcrystals is prevented. ^ In this embodiment, an inner ^ turned wooden leaf 12 is also provided at the lower end of the inner side of the circulation tube 7. There is no particular limitation on the setting method of the inner rotating blade i 2. For example, 'as shown in this embodiment, the base end portion may be mounted on the shaft 19, and the front end portion may be mounted on the inner wall surface of the circulation pipe 7, or the base end portion may be mounted on the shaft 19, respectively. And the front end is not mounted on the inner wall surface of the circulation I 7. However, if the base end portion and the front end portion are both used by female farmers (the former type), the inner rotating blade 12 may have the same function as the above-mentioned support spokes 18, 18 ".
，在本發明中，之所以與沒有設置内側旋轉槳葉的以往 的7式不同、把内側旋轉樂葉設置在流通管7的内側下端 ’是為了把被處理液向旋轉流抑制板推進。通過該推進可 以盡可能i也防止⑯處理液碰撞旋轉流抑制+反而降低該循環 速度。即，以在碰撞到旋轉流抑制板之前、多少提高被處 理液的循環速度的方式，使旋轉流抑制板附近的循環速度 與其他部分的循環速度相同’從而，彳以防止被處理液； 留於旋轉流抑制板附近、或產生紊流。 另外’内側旋轉槳葉對於使被處理液整體循環，只不 過起調整流動的輔助作用（消極的作用）。但不產生結晶 的磨損、破碎。 設有外側旋轉槳葉及内側旋轉槳葉的流通管的「下端 部」的範圍，分別根據旋轉速度、直徑、面積、被處理液 的性質、圓周壁的直徑、流通管的直徑所決定。因而，在 不產生結晶的磨損、破碎的範圍内（若高速旋轉，則下端 4的範圍寬，則結晶的磨損、破碎也增多），適當地設定鲁 。在本實施例中，外側旋轉槳葉8，位於與旋轉流抑制板 1 〇相同南度的位置，且把内側旋轉槳葉丨2設置於比其高一 些的上方。 但是，若被處理液P的旋轉流成為主流，則在圓周壁3 附近被冷卻的被處理液P向流通管7的内側移動的比例會 減少，並在流通管7的内側與圓周壁3附近之間產生溫度 梯度。因此’在圓周壁3附近，被處理液p與致冷劑的溫In the present invention, the reason why the inner rotary blade is provided at the lower end of the inner side of the flow tube 7 is different from the conventional type 7 in which the inner rotary blade is not provided, in order to advance the liquid to be treated toward the rotary flow suppressing plate. By this propulsion, it is possible to prevent the ⑯ treatment liquid from colliding with the swirling flow suppression as much as possible, instead reducing the circulation speed. That is, the circulation speed near the rotational flow suppression plate is made to be the same as the circulation speed of other parts before the collision with the rotational flow suppression plate, so as to increase the circulation speed of the liquid to be treated to prevent the treatment liquid; Turbulent flow near the swirling flow suppression plate. In addition, the 'inside rotating paddle' only plays an auxiliary role (negative role) in adjusting the flow of the whole liquid to be treated. However, no abrasion or breakage of crystals occurred. The range of the "lower end" of the flow tube provided with the outer rotating blade and the inner rotating blade is determined by the rotation speed, diameter, area, properties of the liquid to be treated, the diameter of the peripheral wall, and the diameter of the flow tube. Therefore, Lu is appropriately set within a range in which crystal wear and fracture does not occur (when rotating at a high speed, the lower end 4 has a wider range, and the crystal wear and fracture also increases). In this embodiment, the outer rotating blades 8 are located at the same southerly position as the swirling flow suppressing plate 10, and the inner rotating blades 2 are set a little higher than it. However, if the swirling flow of the to-be-processed liquid P becomes mainstream, the ratio of the to-be-processed liquid P cooled in the vicinity of the peripheral wall 3 to the inside of the circulation pipe 7 will decrease, and the inside of the circulation pipe 7 and the vicinity of the peripheral wall 3 will decrease. There is a temperature gradient between them. Therefore, near the peripheral wall 3, the temperature of the liquid p to be treated and the temperature of the refrigerant

In addition, the degree of supersaturation in the crystallization tank 6 is uneven and fine crystals are liable to be generated. In addition, there is a problem that crystals are deposited, precipitated on the J take-off blade, the operation is blocked, the crystals settle to the lower side of the crystallizing tank 6, and the contact between the k-saturated mother liquor and the crystals is deteriorated. For this reason, the lower-side rotation eight suppression plate 10 is a device provided to convert the rotational flow of the liquid to be processed p into an upper and lower flow. Therefore, there are no specific restrictions on the shape and mounting position, and the design can be changed appropriately. In this embodiment, as shown in the fourth figure, the cross-sectional shape of the lower-side rotational flow suppressing plate 10 is slightly arched (in a state of being expanded in the horizontal flow direction of the liquid P to be treated). The cross-sectional shape is slightly bow-shaped. It is a crime to hinder the rotating flow, and it can effectively flow up and down. Turn the wheat. The installation position of the% flow suppression board 10 is related to the horizontal direction. The position of the inner side of the tube 7 in relation to the upper and lower positions is a state where the front end portion (extended length) of the tube 7 extends into the lower end portion of the flow tube 7. The reason why the lower-side swirl-flow suppressing plate 10 is inserted into the lower end portion of the flow tube 7 is to prevent the swirling flow from passing through the side of the lower-swirl-flow suppressing plate 10 and to prevent the swirling flow. Like the lower swirling flow suppressing plate 10, the upper swirling flow suppressing plate U · is also a device provided for converting the swirling flow of the liquid P to be treated into a vertical flow. For this reason, there are no specific restrictions on its shape and installation position, and design changes can be made appropriately. In the present embodiment, as shown in the fourth figure, the cross-sectional shape of the upper side swirl suppression 11 is set to be slightly bow-shaped (in a state of being expanded in the flow direction of the liquid to be treated p). In addition, the relationship between the mounting position of the upper swirling flow suppressing plate u and the horizontal direction extends from the outer position of the circulation tube 7 to the micro-inside position, and the relationship between the mounting position and the up and down is the front end (13 extension length) ratio flow The upper edge of the tube ^ ^ ^ 9 is slightly higher than the upper position. The outer wall I :: 'r blades 9, 9 ..., are installed on the flow tube 7 19, or the shaft is mounted on the flat rod. The flat wall extending in the downward direction of the °, and the outer wall surface of the parallel tube 7 Above: ^ ° This embodiment shows that the installation is directly installed on the circulation place. There is no specific restriction on the position of the support spokes. For example, the shape of the 9 9 # shape and the mounting position extend to the upper position.

The driving force for the rotation of the driving shaft 19 is taken from the crystals on the inner wall surface 3A of the apple 3T wall 3, solidified Γ by the above-mentioned scraping, and suspended in the treated liquid p to form a slurry. In addition, according to the confirmation by the tester, the length to the diameter square σ of the blades 9, 9, ... is preferably less than 3% of the diameter of the crystallizing tank. Bu Zandan 1 is attached to the inner wall surface of the peripheral wall 3 and the shaft 19 in the crystallizing tank 6: "Luoxia" can form a crystal block. Because the central part of the past was a low-cone-shaped cymbal bottom "in the center The central part collects the block, so even if the knot 14 200407191 soil block: crushing mechanism is installed, it is difficult to completely eliminate the blockage when the treated liquid is discharged IV. Therefore, a conical protrusion is provided at the central part of the bottom of the tank 4 t (Including the groove in the protrusion; £ 4 itself protruding form, and the form of other components.), And the crystal block crushing mechanism 21 is installed on the groove bottom 4 other than the protrusion, due to the crystallization The blocks are concentrated on the outside of the diameter (3 sides of the circumferential wall), so the crystal block can be disassembled. As a result, the clogging failure when the slurry is discharged can be eliminated. In addition, the crushing mechanism 21 of this embodiment is shown in an enlarged view in the third figure As shown, the comb is composed of convex portions 21A, 21 factory installed on the groove bottom 4 and convex portions 21B, 21B, ... which are engaged with the convex portions 2 i A, 21A,... As described above, according to the present invention, the liquid to be processed is circulated and scraped. The device not only prevents the abrasion and fragmentation of the crystal, but also allows the crystal to grow larger and reduce fine crystals.
