[Industrial applications]
The present invention relates to a liquid jetting device and a liquid jetting method using the liquid jetting device. More specifically, the present invention relates to a liquid jetting device for jetting a liquid in a tank body toward a peripheral wall of the tank body and / or an inner peripheral surface of the peripheral wall of the tank body. Alternatively, the present invention relates to a liquid ejecting apparatus and a liquid ejecting method that are sprayed in a space above a liquid surface in a tank.

[Problems to be solved by the invention]
In fermentation and cultivation, both the fermentation liquid and the culture liquid have a large foaming property, and are frequently foamed by stirring during the work, often reducing the workability. An antifoaming agent such as silicon is added to each of the fermentation broth and the culture broth in order to prevent such foaming and to eliminate foam once formed. However, the addition of this antifoaming agent not only requires a large amount of cost, but also has a high risk of adversely affecting fermentation and cultivation since the antifoaming agent itself is a foreign substance. From the product.ExtinctionI have to remove the foamWhatLaAbsentBut thisExtinctionRemoval of the foaming agent is troublesome. In addition, it was added to each of the fermentation broth and the culture broth.ExtinctionThe addition of an antifoaming agent is considered to be an undesirable means and a means to be avoided as much as possible because the foaming agent mixes into the waste liquid and interferes with the waste liquid treatment operation.
[0003]
In addition, for the purpose of defoaming, the disk is rotated in the foam layer on the liquid surface, and the large-diameter lower opening is made to face the liquid surface in the tank body and the frustoconical hollow cylinder is rotated. Attempts have been made to crush the foam with shear forces by such mechanical means. However, such means not only require a great deal of power, but also have the drawback that the foam is simply fragmented and, after all, is often not defoamed.
[0004]
Furthermore, the inner peripheral surface of the peripheral wall of the stirring tank used as each of the fermentation tank and the culture tank is contaminated by the attachment of microbial cells and solid raw materials and products to the inner peripheral surface, thereby reducing the reaction yield. In many cases, the heat transfer coefficient is lowered or the heat transfer coefficient of the peripheral wall of the stirring tank is lowered. In such a case, in order to remove such deposits from the inner peripheral surface of the stirring tank, it is not possible to clean the inner peripheral surface of the peripheral wall of the stirring tank without stopping the operation in the stirring tank. It is virtually impossible.
[0005]
Further, as a heating / cooling device for a liquid in a stirring tank used as a crystallization tank, for example, a jacket, a flexible tube, and a multi-tube bundle are immersed in the outer peripheral surface of the peripheral wall of the stirring tank and / or in the liquid in the stirring tank, respectively. The inner peripheral surface of the peripheral wall and / or the surface of the part immersed in the liquid of the heating / cooling device is used as a heat transfer surface, but the liquid in the stirring tank is reduced by, for example, evaporation. However, the liquid level in the stirring tank decreases with the passage of time, and the heat transfer area of these heating / cooling devices cannot be effectively used in many cases.
[0006]
In order to increase and recover the decreased heat transfer area, a means for supplying new liquid into the tank body to raise the liquid level and circulating the residual liquid in the tank body with a pump installed outside the tank body are used. There may be a method of spraying the heat on the inner peripheral surface of the peripheral wall of the tank, which is the heat transfer surface of the heating / cooling means. In the former case, such a supply of new liquid into the tank body causes a sudden change in the composition of the liquid in the tank body, so that a sudden change in operating conditions is necessary to respond to this, There are also disadvantages such as a change in product quality. Further, the latter requires a pump and a pipe for circulating the residual liquid, and has a disadvantage that the residual liquid remains in the tank body and the pipe after the operation is stopped. Therefore, the former is a means that cannot be actually adopted, and the latter needs to be improved in order to be used in practice. As described above, means to be put to practical use for solving the drawback that the heat transfer area cannot be used effectively has not been found yet.
[0007]
Further, in order to evaporate the liquid in the stirring tank, usually, a heating means is immersed in the liquid or attached to the outer peripheral surface of the peripheral wall of the stirring tank to stir the liquid or to stir the liquid. Alternatively, a method of heating the liquid under reduced pressure or under pressure and evaporating the liquid from the liquid surface is adopted.In this method, the heat of the space on the liquid surface of the liquid heated by the heating means is: It only heats the liquid surface of the liquid and does not use it effectively. The heating of the liquid in the stirring tank is limited to the contact surface with the heating means and the liquid surface, and the heat of the heating means is used effectively. However, there is a disadvantage that the evaporation rate is reduced accordingly.
[0008]
The present inventors have found that conventional uncertain defoaming due to shearing force, contamination of the inner peripheral surface of the peripheral wall of the stirring tank, reduction of the heat transfer area on the inner peripheral surface of the peripheral wall of the stirring tank, and heating installed in the tank body -Eliminates all the drawbacks such as contamination of the heat transfer surface of the cooling device, reduction of the heat transfer area, and delay of evaporation of the liquid in the stirring tank only by mechanical stirring to efficiently and surely extinguish it. Foaming, cleaning the inner peripheral surface of the peripheral wall of the stirring tank, securing the heat transfer area on the inner peripheral surface of the peripheral wall of the stirring tank, cleaning and securing the heat transfer surface of the heating / cooling device, and promoting evaporation of the liquid in the stirring tank As a result of diligent studies on devices and methods capable of all of the above, the inventors have arrived at inventions relating to these devices and methods and have applied for patents earlier (Japanese Patent Application Laid-Open No. 6-335627 and Japanese Patent Application No. 9-329700). ).
[0009]
In these apparatuses and methods, the present inventors require that a sufficient amount of the liquid ejected from the liquid supply be supplied to the tank body in order to spray the liquid in the tank body over as large an area as possible on the inner peripheral surface of the tank body peripheral wall. It is necessary to reach as high as possible the inner peripheral surface of the peripheral wall, but for that purpose, if the inclination angle of the liquid sending is the same, the liquid sending is mounted as the liquid depth becomes shallower and the liquid level decreases We have obtained new knowledge that the rotation speed of the stirring shaft can be increased, and this can simplify the structure.ToBased on this, the present invention has been reached.
[0010]
That is, the first invention,Liquid supply, means for detecting a change in the liquid depth in the tank, and means for changing the rotation speed of the stirring shaft in accordance with the change in the liquid depth in the tank detected by the means are provided.Has a lower opening and an upper opening at each of the lower end and upper end,And,It is attached to the stirring shaft by a fixture, and the lower opening of the liquid feed is provided.IsSubmerged below the liquid levelBe, The upper opening of the liquid sendingIsExposed from the liquid surfaceBeLiquidIsRotate around the stirring shaftBe,A means for detecting a change in the liquid depth in the tank body detects a change in the liquid depth in the tank body, and the stirring shaftRotation speedIs detectedResponding to fluctuations in the liquid depth in the tankBy means of changing the rotation speed of the stirring shaftThe speed of the liquid is changed, and the liquid in the liquid immersion portion of the liquid is raised to raise the liquid, and the liquid is ejected from the upper opening of the liquid to be discharged, so that the inner peripheral surface of the peripheral wall of the tank body and / or the liquid level in the tank body A liquid ejecting device characterized by being sprayed in an upper space.
[0011]
The second invention, the liquid sending liquid of the first invention of the first invention, the lower opening is sunk below the liquid surface, the upper opening is exposed from the liquid surface, and rotated about the stirring shaft,And the rotation speed is changed according to the fluctuation of the liquid depth in the tank body,The liquid in the liquid immersion part of the liquid sending liquid is raised inside the liquid sending liquid, is ejected from the upper opening of the liquid sending liquid, and is sprayed on the inner peripheral surface of the tank body peripheral wall and / or the space on the liquid surface in the tank body. A liquid ejection method characterized by the above-mentioned. Unless otherwise specified in the present invention, "up" and "down" are defined as "position far from the liquid bottom" and "position close to the liquid bottom", respectively.
[0012]
The attachment is for attaching the liquid feed to the stirring shaft. The attachment is a bar-shaped body, a square bar, a steel plate and a plate-shaped body with holes perforated (hereinafter also referred to as a perforated plate-shaped body), or a plate-shaped body without perforations. The unperforated plate and the perforated plate are each preferably mounted horizontally on a stirring shaft so that the fluid resistance does not become excessively large when rotated in a liquid. In addition, when the attachment is immersed in the liquid in the tank body, or the part acts as a stirrer for the liquid.
[0013]
These rods, square bars, profiled steel, vertical perforated plates and vertical, non-perforated plates, respectively, are usually located approximately on the radius or diameter of the plane of rotation. In addition, the center of the horizontal perforated plate-shaped body and that of the horizontal non-perforated plate-shaped body are substantially aligned with the center of the rotation plane. Furthermore, these rods, square bars, shape steel, perforated plates, perforated plates and non-perforated plates may be one, but may be plural, and in the case of plural, usually, May be arranged on the same rotation plane, or may be arranged on different rotation planes.
[0014]
In one fixture, the spraying position of the liquid on the inner peripheral surface of the peripheral wall of the tank body on the radius between the stirring axis and the circumference is within the ejection distance of the ejected liquid from the upper opening of the liquid sending liquid. Normally, only one liquid feed needs to be provided, but this does not prevent provision of a plurality of liquid feeds on this radius.
[0015]
The liquid ejection device of the present invention is such that the rotation speed of the stirring shaft is changed in response to the fluctuation of the liquid depth in the tank body. For example, as the liquid depth in the tank body becomes shallower, the rotation of the stirring shaft becomes smaller. By increasing the rotation speed, the rotation of the liquid feed is increased. For this purpose, the liquid depth in the tank is detected, and the detected liquid depth is transmitted, for example, via a controller or a computer, to a rotational speed transmission device mounted on a motor for driving a stirring shaft such as an electric motor. Preferably, the rotation speed of the motor is adjusted to a rotation speed corresponding to the liquid depth. The stirring shaft and the driving motor for driving the stirring shaft are connected to each other directly or indirectly via respective belts and gears.
[0016]
Also, for example, as the liquid depth in the tank becomes shallower, the load on the prime mover such as an electric motor and the torque of the stirring shaft decrease, but the load on the motor and the stirring shaft corresponding to the change in the liquid depth in the tank become smaller. A change in the magnitude of each of the torques can be detected and used in place of the detection of the liquid depth. That is, a current value corresponding to a predetermined magnitude of each of the load of the motor and the torque of the stirring shaft is set in advance (the set current value is hereinafter referred to as a set current value). When the magnitude of the load and the torque of the agitating shaft decrease, and the current value supplied to the motor decreases, the motor is controlled to compensate for the difference between the set current value and the reduced current value. Is increased, the rotation speed of the motor is increased, the current supplied to the motor reaches the set current value, and the motor is restored to the rotation speed corresponding to the set current value. In this case, it is preferable that the upper limit of the rotation speed of the electric motor is set arbitrarily in advance so that the rotation speed does not exceed the capacity of the liquid ejection device. Means known per se can be applied to change the rotation speed of the motor in response to a change in the liquid depth.
[0017]
Inside the tankMeans for detecting fluctuations in the liquid depth itself (hereinafter  Liquid depth detection meansSometimes written)Usually, a liquid level gauge is suitably used. The liquid level gauge detects fluctuations in the liquid level inside the tank and detects the detected liquid depth.itselfThere is no particular limitation as long as it is a device or device capable of transmitting a message. Suitable representative examples thereof include a differential pressure transmitter such as a differential pressure pilot and a float transmitter such as a float pilot. A commercially available product can be used as the liquid depth detecting means. Further, the liquid depth in the tank can be visually detected, and the rotation speed of the electric motor for driving the stirring shaft can be manually adjusted accordingly.
[0018]
Stirring shaft torque and prime mover loadAs a means to detectUsually, each of a torque meter and a dynamometer is preferably used. Commercially available products can be used for the torque meter and the dynamometer.A rotation speed transmission is used as a means for changing the rotation speed of the stirring shaft in response to the detected fluctuation in the liquid depth in the tank.Representative examples of suitable rotational speed transmissions include an electric motor equipped with an inverter (hereinafter referred to as an inverter transmission), a Bayer transmission (trade name), and a ring cone transmission (trade name). Above all, an inverter transmission is preferred.
[0019]
Inverter means a reverse converter, and is a method or a device that converts a direct current into an alternating current. In the inverter transmission, the primary frequency of the AC motor is changed by the inverter, and the rotation speed of the motor is changed. Note that the inverter preferably has a motor stall prevention function. The motor stall prevention function of this inverter detects a change in liquid depth, a change in the load of the prime mover and a change in the torque of the stirring shaft, and the magnitude of the load of the prime mover and the torque of the stirring shaft become constant. Thus, the rotation speed of the prime mover can be controlled, and stall during operation of the liquid ejection device can be prevented. A commercially available product can be used as the rotation speed transmission.
[0020]
With the above-described rotational speed transmission device, it is possible to automatically control the load of the prime mover and the magnitude of the torque of the stirring shaft to be constant. For this purpose, for example, when the rotational speed transmission is a Bayer transmission, an electric automatic remote control device is mounted instead of the manual transmission handle, and a signal from a dynamometer or a torque meter is used for electric automatic remote control. If the current value corresponding to the magnitude of the load of the motor and the torque of the stirring shaft sent by this signal is different from the current value preset in the controller, the current value is sent to the controller of the operating device. A signal about the difference is sent to the speed setter and the speedoperationAn electrical signal is sent to the device to cause the speed change handle to rotate forward or reverse, thereby increasing or decreasing the rotational speed of the Bayer transmission, thereby increasing or decreasing the rotational speed of the motor.
[0021]
In the controller of the electric automatic remote control device, the torque of the stirring shaft sent by the signal from the torque meter or the dynamometer orRespond to loadIf the magnitude of the power of the motor does not differ from the preset torque or the magnitude of the power, the rotation speed of the Bayer transmission, that is, the rotation speed of the motor is not changed and the motor is rotated at a constant speed. Note that a digital controller is usually used as the controller, but an analog controller can also be used.
[0022]
The controller is also referred to as a blind controller or a controller, has a function of automatically controlling a control amount in an automatic control device, includes a setting unit and a control unit, and receives an externally supplied signal (control amount). ), For example, the magnitude of the torque, and a value set in advance in the setting unit, by the adjustment unit in the proportional operation, the differential operation or the integral operation or the proportional operation, the differential operation, and the integral operation. This is a control device that emits a signal and adjusts it so that it is reduced by using two operations in combination. A commercial item can be used as a controller. In addition, a controller can be connected to the inverter. In this case, even if the inverter does not have a stall prevention function, the frequency can be changed by a signal from the controller, which is preferable.
[0023]

One or a plurality of narrow liquid feeds can be provided in one fixture. In the case where a plurality of thin liquid feeds are provided in one fixture, the upper openings and the lower openings of the thin liquid feed are respectively located on either the substantially same rotation plane or the different rotation plane.

It is practically preferable that the direction of the lower bent portion is slightly downward from vertical or horizontal. Further, it does not prevent the upper portion of the straight pipe portion from being bent obliquely upward or obliquely downward to form a bent portion as required. Each of the bent portions at the lower and upper portions of the tube can be formed by bending the tube, but another tube is connected to the end of the straight tube portion of the tube by, for example, welding and screwing. Can also be formed.

Of a polygon. Thus, the respective shapes of the upper opening and the lower opening may be substantially the same as each other, or may be different from each other. Preferably, the lower opening is larger than the upper opening.
[0031]
The upper opening of the tube may be closed with a perforated plate, and the upper opening may be formed in a funnel shape to form a shower spray type. In this case, the total area of the holes in the perforated plate is the area of the upper opening. The upper opening of the tubular body is a blind tube, and a number of holes are formed as openings in the blind tube to form a spray type. In this case, the total area of the large number of holes is the area of the upper opening.

If the cross-sectional shape of the upper edge or upper edge and the lower edge or lower edge is an asymmetric open shape, these shapes and the extension end and other openings This is the area of the closed shape surrounded by a straight line connecting the ends or the area of the closed shape surrounded by a straight line connecting both open ends excluding these shapes and the extension.
[0038]
There is no particular limitation on the shape of the side surface of the gutter-like body (hereinafter also referred to as a side surface shape), but as a whole, it is usually curved with a small curvature so as to bulge straight, upward or downward. The simulated curve and the straight line and the curveeachThe upper end and / or the lower end may be formed in an S-shape further extending horizontally or below the horizontal direction. The curve is preferably a parabola. Particularly, a straight line is preferable because the gutter-like body can be easily formed. In addition, since the ejection distance and / or the ejection amount of the liquid can be increased, a curve which is swollen downward and is curved is preferable, and a parabola which is swollen downward and is curved is particularly preferable.
[0039]
There is no particular limitation on the shape of the gutter-like body as viewed from the front (hereinafter, also referred to as the front shape), but as a whole shape, it is usually a straight line, a small curvature and a lateral direction (parallel to the rotation plane of the gutter-like body). The same applies to the following curves)eachThe upper and / or lower ends may be S-shaped with a further lateral extension, but straight lines are preferred.

Further, the lengths of the plurality of gutter-like bodies attached to the fixture may be the same as each other, or may be different from each other. The side edges of the upper surface openings of the plurality of gutter-shaped bodies or the walls of the gutter-shaped bodies are abutted with each other to be connected to each other, or the inside of the gutter-shaped bodies is divided by a partition wall provided along its long axis and connected.

Further, the gutter-shaped body may have its upper opening closed by a plate body with a gap along the inner peripheral surface of the gutter-shaped body. Further, the upper surface opening of the gutter-like body can be removed and closed with an opaque or transparent lid. Furthermore, in order to rapidly change the direction of the liquid ejected from the upper opening of the gutter-like body, a reflecting plate can be provided separately from the upper opening.
[0043]
Also, the trough does not prevent it from being twisted as long as it can raise the liquid or being rotated about its long axis. In this case, the angle at which the gutter is twisted or rotated is appropriately selected according to the opening shape of the gutter, the size of the inclination angle, the viscosity of the liquid in the container, the rotation speed of the gutter, and the like. .
[0044]
In the latter case, the gutter may be pivotally mounted on the fixture. In this case, the gutter-shaped body can be fixed after being directed to a predetermined deflection angle, or can be automatically rotated according to the rotation speed of the gutter-shaped body. In this case, the gutter is rotatably mounted on the stirring shaft.
[0045]
Further, the trough-shaped body has its concave surface and upper surface opening oriented in a circle or a rotation direction of the plane of rotation of the gutter-shaped body, preferably facing the stirring shaft or the rotating direction, and attached to the stirring shaft by a fixture. Can be The degree of the respective directions of the concave surface and the upper surface opening of the gutter-like body with respect to the stirring shaft is indicated by the magnitude of the deflection angle. The deflection angle is defined similarly to the deflection angle in dynamics. That is, in the cross section of the opening of the gutter-like body or the cross-section of the gutter-like body in the plane of rotation, three points arbitrarily selected from the region to be advanced to the region to be posterior according to the direction of rotation, A, Assuming that B and C are D and the rotation axis on the same plane as the opening or cross section of the gutter-like body (the center of the stirring axis, the same applies hereinafter), these points A, B, C and D satisfy the following conditions. Is to be satisfied.
[0046]
That is, (1) the distance between B and D ≧ the distance between C and D, and (2) the angle formed between the line segment AB and the base line BD {the angle formed between the line segment BC and the base line BC and the base line BD} Let CBD be θ₁And θ₂If the gutter is rotated clockwise (clockwise), θ₁Is θ₁Is given in a region that is ahead of the base line BD, a plus sign (+) is given. In a region that is behind the base line BD, a minus sign (-) is given.₂Is θ₂Is placed in a region that is later than the base line BD, a negative sign (-) is added, and in a region that is ahead of the base line BD, a positive sign (+) is added. Also, when the gutter is rotated counterclockwise (counterclockwise), θ₁And θ₂Are the same as those when the gutter is rotated clockwise (clockwise), for example, θ₁Is θ₁Is located in a region that precedes the baseline BD, a plus sign (+) is added.
[0047]
Thenθ ₁ And θ _Two Is preferably −75 ° ≦ θ.₁≦ 110 ° and −75 ° ≦ θ_Two≦ 110 °. Thus, the magnitude of the deflection angle is (θ₁+ Θ_Two) / 2. Therefore, θ₁And θ_TwoWhen the respective absolute values of are equal to each other, the deflection angle becomes zero.
[0048]
The magnitude of the deflection angle is appropriately selected from the above range depending on the shape of the gutter-like body itself and the shape of the opening, the ratio of the opening area of the upper opening to the lower opening, the use of the jet liquid, and the like. When attaching the gutter to the fixture, the fixture must not prevent the liquid from rising within the concave surface of the gutter. The rotation of the liquid sending of the plate body is the same as that of the liquid sending of the gutter-like body.
[0049]
The above-mentioned narrow liquid sending liquid can be provided with one or more through-holes in its peripheral wall, which is preferable. A plate can be attached at an interval from the outside of the through hole (the side close to the peripheral wall of the tank body, and so on). With this plate, the direction in which the liquid ejected from the through hole is ejected can be changed. In addition, a tube and a spray nozzle can be radially provided outside the through-hole in the narrow liquid feed. The liquid that has passed through the narrow liquid feed is ejected outward from a through hole formed in the wall of the narrow liquid feed. By selecting the size of the through hole, a desired amount of the liquid passing through the narrow liquid feed can be ejected from the through hole.
[0050]
The narrow liquid feed may be bendable and / or telescopic. To make the thin liquid feed bendable, for example, the liquid feed may be made of a flexible material, or the thin liquid feed may be divided into a plurality of pieces laterally (substantially perpendicular to the long axis). The plurality of liquid supply fragments thus formed may be connected to each other so as to be rotatable by joints. Further, in order to make the thin liquid feed expandable and contractable, for example, the thin liquid feed is formed by fitting a plurality of liquid feed pieces divided into a plurality of pieces perpendicularly to the long axis thereof and slidably connected along the long axis. It is made possible by setting it up.
[0051]
When a plurality of the thin liquid feeds are fixed to the fixture, the plurality of thin liquid feeds may be independent of the fixture, or may be integrated with the fixture. . As a typical example of the gutter-like body integrated with the fixture, for example, a plate is used as a fixture, and a non-horizontal side of the plate that is a fixture is substantially a side along the side. It is bent in parallel, or the lower apex is bent and bent along the side, and the gutter-like body abuts the upper opening side edge to the edge of the opposite side of the plate body that is not horizontalhandA triangular or quadrangular flat plate or a curved plate which is bent outward at a small curvature at an arbitrary angle is joined to the edge of a non-horizontal opposite side of the plate. Gutter-like bodies.
[0052]
In this case, the plate used as the attachment is usually preferably a triangular plate and a rectangular plate such as an inverted trapezoid, a rectangle and a square, but a plate having any other shape is preferable. Do not disturb. In the gutter-shaped body thus formed, the upper opening and the lower opening each have an asymmetric shape. The unfolded flat plate portion of the mounting plate acts as a stirring blade. A hole is formed in the flat plate portion of the plate body so that the fluid resistance of the plate body serving as the fixture is not excessive, and the fluid resistance here can be reduced, which is preferable.
[0053]
The thin liquid feed is mounted radially in parallel with the stirring shaft or with the lower opening closer to the stirring shaft than the upper opening. In the latter case, since the amount of liquid ejected from the upper opening becomes large, the thin liquid is centripetally mounted by aligning its long axis with the radial direction of the rotating plane corresponding to the mounting direction of the mounting fixture. Being attached to the fixtureIs goodPreferably, it is mounted eccentrically in a direction different from the above-mentioned radial direction.KeIt does not prevent that being done. When the thin liquid feed is mounted eccentrically, the long axis of the thin liquid feed may be parallel to the radial direction on the rotation plane corresponding to the mounting direction of the fixture, or may be inclined. May be. In the case of being eccentrically inclined, it is preferable that the lower opening is eccentric so that the lower opening precedes when the liquid supply is rotated.
[0054]
In the thick liquid transfer, the upper bottom opening and the lower bottom opening are the upper opening and the lower opening, respectively. The stirring shaft is passed through the center of each of the upper opening and the lower opening of the thick liquid sending liquid. Thus, the thick liquid feed is attached to the stirring shaft by the attachment.
[0055]
The liquid feed is fixed to the fixture at a predetermined inclination angle, or mounted so that the inclination angle can be arbitrarily adjusted. The latter is preferable. In the case of a thin liquid feed, the inclination angle is defined as an angle between the long axis line and the rotation plane of the thin liquid feed, and in the case of a thick liquid feed, the generatrix of the peripheral wall of the cylindrical body is used. Is defined as the angle between the rotating liquid and the plane of rotation of the thick liquid supply. This fixation can be performed by a conventional method such as fitting, welding, or bonding. Here, the long axis of the thin liquid sending is defined as a line connecting the center or the middle point in each of the upper opening and the lower opening of the liquid sending.
[0056]
Thus, the inclination angle of the liquid sending is set in a range of more than 0 ° to 90 °. As a result, in the thin liquid feed, the lower opening is closer to the stirring shaft than the upper opening or the distance from the stirring shaft to the lower opening and the upper opening is substantially equal to each other. The former is preferred. In the latter case, it is preferable to close the lower opening when the thin liquid feed is a gutter-like body. Also in this case, the liquid in the liquid immersion portion of the trough is raised in the trough. The magnitude of the tilt angle of the liquid to be sent depends on the shape of the liquid itself and the opening shape, the ratio of the opening area of the upper opening to the lower opening, the type of liquid, the rotation speed of the liquid to be sent, the head of the ejected liquid ( The height at which the ejected liquid reaches on the peripheral surface.,It is appropriately selected according to the ejection distance, the ejection amount, and the like, but is usually preferably about 5 to 85 °.
[0057]
In order to attach the thin liquid feed to the stirring shaft so that the magnitude of the inclination angle can be adjusted, for example, the lower end of the thin liquid feed is hinged to the stirring shaft, and the vertical moving means or the horizontal moving means is used. It is sufficient to mount the thin liquid feeder so that the upper opening can be moved centrifugally or centrifugally along the radial direction of the rotation plane. Here, the vertical moving means and the horizontal moving means are means for adjusting the inclination angle of the narrow liquid sending by vertically pulling up or down the upper end, which is the free end of the narrow liquid sending, and the free end of the narrow liquid sending, respectively. This is a means for adjusting the inclination angle of the narrow liquid sending by narrowing or pushing the upper part in the horizontal direction. In the above description, the movement of the upper opening of the thin liquid transfer by the vertical movement means and the movement by the horizontal movement means may be hereinafter referred to as a vertical method and a horizontal method, respectively.
[0058]
Further, the length of the thin liquid feed is made longer than the radius of the rotation plane, the lower end of the thin liquid feed is hinged to the stirring shaft, and the upper end is slid in contact with the inner peripheral surface of the peripheral wall of the tank body. By doing so, it can be inclined. In this case, by changing the length of the narrow liquid sending, the inclination angle of the narrow liquid sending can be adjusted. Also, the length of the thin liquid feed is made longer than the winding diameter of the coiled tube (the distance from the center of the coiled tube to the inner circumference) installed in the tank body, and the lower end of the thin liquid feed is used as the stirring shaft. It can be tilted by hingedly and sliding the lower surface against the inner peripheral surface of the upper end of the flexible tube. In this case, the lower end of the thin liquidMountingBy changing the position (the distance from the bottom of the tank body), the inclination angle of the narrow liquid feed can be adjusted.
[0059]
The mounting device to which the liquid feed is attached is mounted on a stirring shaft, the liquid sending is submerged in the lower opening below the liquid surface, the upper opening is exposed from the liquid surface, and the stirring shaft is rotated to rotate the liquid sending liquid. ToAround the stirring shaftBy causing the liquid to rotate (this rotation may also be referred to as a revolution), the liquid in the liquid immersion part of the liquid is raised inside the liquid by centrifugal force according to Bernoulli's theorem (Bernoulli's theorem). Then, the liquid is ejected from the upper opening, and the part below the liquid surface of the liquid feed also acts as a stirring blade, and the liquid is stirred in this part.
[0060]
The upper-bottom opening and the lower-bottom opening of the thick liquid sending liquid are an upper opening and a lower opening, respectively, and the inner peripheral surface of the peripheral wall of the cylindrical body that is the thick liquid sending liquid is a liquid flow path. In the liquid ejection method of the present invention, the rotation speed of the liquid sending is appropriately selected depending on the liquid depth in the tank, the inclination angle of the liquid sending, the type of the liquid sending, the shape and thickness of the liquid sending, the type of the liquid, and the like. obtain. By revolving the liquid to be sent, the liquid level in the tank body rises on the inner peripheral surface of the peripheral wall of the tank body, and decreases around the stirring shaft, giving a funnel shape, and the liquid level is lower than the lower opening of the liquid sent. And the liquid in the tank no longer rises in the liquid supply. In this case, the liquid surface in the tank is flattened by revolving the liquid supply in the opposite direction.
[0061]
Thus, the rotation of the stirring shaft is increased in response to the decrease in the liquid level in the tank, and the rotation of the liquid sending is also increased accordingly. In this way, the liquid in the tankVia the liquid feedIt is sprayed to a space above the liquid level inside the tank body and / or a desired high place on the inner peripheral surface of the tank body peripheral wall.
[0062]
The ejected liquid ejected from the upper opening of the liquid to be sent is sprayed on the foam layer formed on the liquid surface in the tank body to eliminate bubbles. (B) Spraying the inner peripheral surface of the peripheral wall of the tank body to wash the inner peripheral surface of the peripheral wall of the tank body. (C) Spray the heat transfer surface of the heating / cooling device installed in the tank body to clean the heat transfer surface. (D) When the liquid level in the tank falls, the heat transfer area is secured by dispersing it on the inner circumferential surface of the tank peripheral wall or the heat transfer surface of the heating / cooling device installed in the tank body. I do. And / or (e) spraying in a space above the liquid level in the tank body to promote evaporation of the liquid in the tank body. Used for In the case of the above (e), the inside of the tank can be depressurized or pressurized. When the pressure in the tank is reduced, the droplets sprayed in the space above the liquid surface in the tank are instantaneously boiled and evaporated, which is preferable. In addition, since the liquid sprayed on the heat transfer surface of the heating / cooling means forms a thin film on the heat transfer surface and is rapidly heated and cooled, the required time is shortened, and the energy loss is reduced accordingly. I can do it.
[0063]
The size of the liquid ejection device of the present invention is not particularly limited, and may be any size. Usually, for example, a large-scale one used in a large tank in a manufacturing apparatus in a factory is preferable, but a small-scale one used in a laboratory used in a flask, for example, can also be used. . In the liquid ejecting apparatus of the present invention mounted in the flask, any of the thin liquid feed and the thick liquid feed can be used as the liquid. When the liquid to be sent is a thin liquid sending liquid, the narrow liquid sending liquid is set at an inclination angle of about 90 °, the upper end thereof is close to the stirring shaft, and the narrow liquid sending liquid is passed through the mouth of the flask, and then attached to the flask. The narrow liquid feed can be opened and fixed at a desired tilt angle, or the upper end of the thin liquid feed can be brought into sliding contact with the inner peripheral surface of the flask to have a predetermined tilt angle. The tilt angle of the liquid may be adjustable in a vertical manner. When the liquid is a thick liquid, a separable flask is usually used as the flask. In the liquid jetting method of the present invention, the liquid in the tank may be a viscous liquid or a suspension having a high concentration of dispersoid.

The connecting rod 63 is fixed to the stirring shaft 3 by the rotating ring 32 by the thumb screw 323 when the inclination angle of the tube 5 becomes a desired size.
[0101]
In the liquid ejecting apparatus in which the tube 5 whose inclination angle can be adjusted by the horizontal method shown in FIG. 15 is a thin liquid sending device, a free end (a thin type) of a connecting rod 63 is used instead of the thumb screw 323. By providing a stopper (not shown) on the side (the end not connected to the tube 5 that is the liquid feed), the tube 5 that is the thin liquid feed can be inclined at a desired inclination angle. In this case, the inclination angle can be adjusted by changing the position of the stopper.
