  Thus, since both the apparatus described in Patent Document 1 and the apparatus described in Patent Document 2 require a plurality of treatment tanks, not only the equipment cost of the entire apparatus is very high. Since the installation area also becomes large, the range of utilization is limited. Furthermore, in any of the apparatuses, it is explained that the object to be treated is completely decomposed and vaporized in the final stage treatment tank so that no solid residue remains. However, it is necessary to clean the inside of the tank periodically to remove the solid residue, and if this maintenance work is neglected and the product is used for a long period of time, the increased residue prevents normal decomposition. This will cause functional degradation. In addition, as described in Patent Document 2, in a configuration in which a filtration net that separates and removes coarse organic substances is used in combination, an operation for removing the filtration net at an appropriate time and transferring it to a drying position in the tank, a new filtration net is added. It is necessary to carry out all manual work, such as setting work, filtering net contents to be taken out of the tank and disposing it, and it is necessary to perform maintenance work that requires time and labor. In combination with the maintenance work for removing the residue, a large maintenance cost is required.

An object of the present invention is to provide a feces and urine treatment apparatus capable of solving the above-described conventional problems, and when the means is shown with reference numerals of embodiments to be described later, it is sent out with water. in one processing bath 1 to accept been hydrolyzed manure, a heating means 7 for heating an object of the treatment tank 1, and blowing means 8 for stirring and aeration by feeding air into the object to be processed The residue discharge means 16 is provided for taking out residues from the take-out area to the upper side in the treatment tank by taking the entire height range from the lowest water level L to the highest water level H in the treatment tank 1 as an extraction area.

The partition spaces A1 to A3 that can be drained are constituted by a space surrounded by two radial partition walls 37a to 37c, a fixed bottom plate 34, and a fixed peripheral side plate 32 that are adjacent to each other in the circumferential direction of the rotating body 30. In addition, the fixed bottom plate 34 may not be provided at the dry residue discharge position P3 .

Further, as described in claim 3 , the residue discharge means 16 rotates a vertical rotation circulation path passing through the inside of the treatment tank 1 and the residue discharge position above the treatment tank 1, and the residue discharge state at the residue discharge position. From the partition spaces A1 to A3 that are disposed between the residue discharge position and the processing tank 1 and accept the residue discharged from the bucket 19 and that are automatically switched to The residue temporary storage part P1 which consists of can be provided. In the case of adopting the configuration according to claim 3, as described in claim 4, the residue discharging means 16 includes a rotary arm 17 that is driven to rotate around a horizontal axis, and a free end of the rotary arm 17. A residue-pumping bucket 19 suspended in a swingable manner by a support shaft 24 parallel to the horizontal axis, and the rotation of the rotary arm 17 when the bucket 19 reaches the residue discharge position. The bucket 19 can be configured to include a fixed contact member 26 that reverses the bucket 19 to a residue discharge state .

Further, as described in claim 5 , a hydrolyzed urine receiving port 3 is provided on one end side of the processing tank 1, and the residue discharging means 16 is provided on the other end side of the processing tank 1 facing the hydrolyzed urine receiving port 3. An arranged area (residue discharge area 5) is provided, and in the treatment tank 1 at a position between this area (residue discharge area 5) and the hydrolyzed urine receiving port 3, the area (residue discharge area 5) A net 14 can be stretched to prevent foreign objects or the like of a certain size or more from entering the cable .

Further, as described in claim 6 , the hydrolyzed urine receiving port 3 is provided at one end of the processing tank 1 , and the residue discharging means 16 is disposed at the other end side of the processing tank 1, and the object to be processed in the processing tank 1 is provided. Horizontal rotation flow generating means for generating a flow in the horizontal rotation direction can be added to at least the surface layer of the substrate. As the horizontal rotating flow generating means, as described in claim 7, an air supply blower 49 for generating a horizontal rotating air flow in the upper space in the processing tank 1 and an exhaust path (exhaust tube 50 from the processing tank 1). And a pump 54, 55 that sucks and discharges the object to be processed in the processing tank 1, as described in claim 8. When the workpiece suction / discharge pumps 54 and 55 are used in this way, as described in claim 9, the workpiece suction / discharge pump 55 is externally connected to the workpiece suction / discharge pump 55 using the flow of the workpiece to be processed. An air pull-in injection pump unit 65 that draws and mixes air into the discharge workpiece can be provided.

  According to the feces and urine treatment apparatus of the present invention having the above-described configuration, it can be configured using only one treatment tank that receives the water-washed and sent out hydrolyzed urine, and the conventional treatment tanks and the treatment tanks are covered with each other. Compared with an apparatus assembled with a connecting pipe for flowing a processed material, the equipment cost can be greatly reduced and the installation area can be greatly reduced. Thus, hydrolyzed manure is decomposed by stirring and aeration by heating and air feeding in one treatment tank, but in reality, some solid residue is generated. This solid residue is usually in the form of fine particles or strips and floats on the surface layer of the object to be treated, but by operating the residue discharge means at appropriate time intervals, regardless of the water level in the treatment tank. The solid residue can be taken out of the treatment tank, and the taken-out residue is stored in the residue temporary storage unit and left to drain for an appropriate period of time, and the amount of residue in the residue temporary storage unit reaches an appropriate amount. By operating the residue conveying means, the residue draining residue in the residue temporary storage unit can be sent to the residue drying unit, and the residue can be left in the residue drying unit for an appropriate period to be completely dried. Accordingly, as the residue treatment work for the apparatus of the present invention, it is only necessary to dispose of the dried residue in the residue drying section at an appropriate time, and the residue treatment work is extremely easy and costs little, but from the inside of the treatment tank. It is not necessary to cause the inconvenience that occurs when the residue is left without performing the removal operation, that is, the inconvenience that the normal decomposition capacity in the treatment tank is lowered.

Furthermore , according to the configuration of the present invention, the step of storing the residue taken out each time in the residue temporary storage unit for a certain period of time and draining the residue until reaching a predetermined amount, and the predetermined amount in which the residue storage in the residue temporary storage unit has been completed for a certain period of time. The step of transferring the drained residue to the residue drying unit, the step of leaving it for the storage period of the residue taken out in the next residue temporary storage unit, and the step of taking out the residue after drying from the residue drying unit and putting it into the transport case Can be automatically executed by intermittently rotating a plurality of circumferentially drainable partition spaces around the vertical axis around the vertical axis by a predetermined angle at appropriate time intervals, The maintenance worker simply disposes of the dried residue using a removable carrying case. Moreover, according to the structure of Claim 2, compared with the structure which rotates each container-shaped division space provided with the bottom and the surrounding wall separately, the bottom of the division space is opened at the dry residue discharge position. This eliminates the need to open and close the bottom of each compartment space and eliminates the need to automatically open and close the bottom of the compartment space when the dry residue discharge position has been reached. it can be.

Furthermore, according to the configuration of the third aspect, it is only necessary to configure the vertical rotation circulation path so that the minimum height position of the vertical rotation circulation path of the residue pumping bucket is near the bottom in the treatment tank. Regardless of the water level of the object to be treated in the tank, the residue can be surely pumped out from the object to be treated. Moreover, since the residue discharge position at which the residue-drawing bucket is automatically switched to the residue discharge state is located above the treatment tank, the drainable compartment of the residue temporary storage section disposed below the residue discharge position Moisture dripping from the space can be returned directly into the treatment tank without providing a special water channel. When adopting the configuration according to claim 3, according to the configuration according to claim 4, in order to automatically switch the residue pumping bucket to the residue discharge state at the residue discharge position, the bucket has a special structure, For example, there is no need to provide an openable / closable bottom and the like, and it is only necessary to provide a fixed abutting member at the residue discharge position. Therefore, the residue discharge means is configured so that the residue pumping bucket rotates in a vertical rotation circulation path. It can be carried out easily and inexpensively .

Moreover, according to the structure of Claim 5, the situation which the foreign material accidentally sent into the processing tank with the water droppings entangled with the residue discharge means can be avoided, and it takes time to decompose. It is possible to avoid the disadvantage that the coarse solid organic matter is discharged by the residue discharging means without being decomposed.

Moreover, according to the structure of Claim 6, the pouring position of the hydrolyzed manure into the processing tank and the residue discharging means are separated by the length of the processing tank, and the hydrolyzed manure flowing into the processing tank There is less possibility that the solid content will be discharged as it is by the residue discharging means. On the other hand, since the flow in the horizontal rotation direction is generated in at least the surface layer of the object to be processed by the horizontal rotation flow generating means, the residue generated by the decomposition process of the object to be processed and floating in the surface layer is not contained in the processing tank The surface layer flows over substantially the entire area. Therefore, although the residue discharging means is disposed at the end of the processing tank, the generated residue can be reliably captured by the residue discharging means and discharged out of the processing tank .

In the case of adopting the horizontal rotation flow generating means described above, according to the configuration of claim 7, a flow in the horizontal rotation direction is directly generated in the processing object itself by a pump for sucking and discharging the processing object. It can be carried out more easily and cheaper than the case, the maintenance of the means can be easily performed, and the ammonia gas in the upper space in the treatment tank is promptly decomposed by the air sent from the outside and is not brominated. It can be discharged in a state. In other words, means for supplying the outside air into the upper space in the processing tank and exhausting the air from the upper space, which are essential for this type of manure processing apparatus, can be used as the horizontal rotating flow generating means. It can be done. Of course, the horizontal rotation flow generating means may be provided separately from the means for supplying outside air into the upper space in the processing tank and exhausting the air from the upper space. For example, according to the structure of Claim 8, when a to-be-processed object is sucked and discharged by a pump, it will receive a grinding | pulverization stirring effect, and can decompose | disassemble a to-be-processed object efficiently. Furthermore, according to the configuration of the ninth aspect, not only can the horizontal rotating flow be generated in the workpiece, but also the outside air is forcibly discharged into the workpiece in the horizontal rotating flow state. The decomposition of the processed product can be promoted. Therefore, by increasing the capacity of the injection pump unit provided in the pump that constitutes the horizontal rotation flow generating unit, the air supply unit that feeds air into the object to be agitated and aerated is used in the injection pump unit. In addition to the pump as the horizontal rotation flow generating means, the cost can be reduced as compared with the case where an air supply pump that supplies air into the object to be processed and performs agitation and aeration is provided .

In addition, when using the means for sending outside air into the processing tank (in the upper space or into the object to be processed) as the horizontal rotating flow generating means as described above, or in the processing tank separately from the horizontal rotating flow generating means. When a means for supplying outside air into the upper space and exhausting from the upper space is provided, the atmospheric pressure in the upper space in the treatment tank becomes lower than the atmospheric pressure (becomes a negative pressure state). As described above, the exhaust capacity of the exhaust means used in combination is increased so that the odor in the treatment tank can be prevented from flowing back when using a toilet that feeds hydrolyzed urine into the treatment tank, and the treatment object is vaporized and generated. It is desirable to activate decomposition-free bromination of ammonia gas and the like.

Regions 32a and 34a are formed. The rotary body 30 is concentric with the center position of the circular arc in the plan view of the peripheral side plate 32 of the fixed case 29, and is a vertical rotary shaft 35 supported on the top plate 33 and the bottom plate 34 via bearings. Each of the radial partition walls 37a includes a cylindrical body 36 fixed concentrically, and radial partition walls 37a to 37c parallel to the rotation shaft 35 protruding from the cylindrical body 36 at intervals of 120 degrees in the circumferential direction. The lower side of the parallel side plates 38 that form .about.37c is adjacent to the bottom plate 34, and the front end face plate 39 that connects the front ends of the parallel side plates 38 is configured to be rotatable adjacent to the peripheral side plate 32.

  The rotation driving means 31 is located immediately below the top plate 33 of the fixed case 29 and has a large-diameter spur gear 40 concentrically fixed to the upper side of the radial partition walls 37a to 37c of the rotating body 30 and the rotation shaft 35.

It protrudes into the cover 27 from the side wall 15b. Further, a dry residue carrying case 47 is detachably supported just below the cover 27 with the upper end of the case fitted inside the cover 27.

  Further, an air supply blower 49 for sending outside air along one left and right side walls in the processing tank 1 via an elbow pipe 48 is provided on one of the left and right ends of the rear end side wall portion 1b of the processing tank 1 and protrudes. An exhaust blower 51 is disposed through an exhaust cylinder 50 at the end of the upper end of the case portion 15 opposite to the side where the air supply blower 49 is disposed. The air supply blower 49 is provided at a position higher than the maximum water level H of the object to be processed set in the processing tank 1, and the pressure air discharged from the air supply blower 49 is processed in the processing tank 1. Regardless of the water level of the object, it is fed into the upper space formed above the object to be processed in the treatment tank 1 through the elbow pipe 48, and after turning in the upper space horizontally, the exhaust pipe 50 is passed through. The exhaust blower 51 is configured to be sucked and discharged. At this time, the exhaust ability from the processing object upper space by the exhaust blower 51 is higher than the air supply capacity to the processing object upper space by the air supply blower 49, and the processing object upper space becomes a negative pressure from the atmospheric pressure. It is configured as follows.

  As shown in FIGS. 2 and 3, the treatment tank 1 is provided with a float 52 that moves up and down according to the water level of the object to be treated in the treatment tank 1, and the inside of the treatment tank 1 is determined from the height of the float 52. A detection device 53 for detecting whether or not the water level (accommodation amount) of the object to be processed is between the lowest water level L (minimum accommodation amount) and the highest water level H (maximum accommodation amount) is provided. Detects the maximum water level H (maximum capacity), a warning lamp indicating that the use of the toilet 4 connected to the apparatus is prohibited lights up, and the detection device 53 detects the minimum water level H (minimum capacity). At this time, automatic control such as stopping the heating of the object to be processed by the heating means 7 (heater) is performed.

  The method of using the feces and urine treatment apparatus of the present invention having the above-described configuration will be described. The whole area is stored and heated by the heating means 7 to be maintained at the set temperature, and the agitating and aeration action is performed by the pressurized air from the pressure air delivery device (air supply blower) 12 ejected from the air supply means 8. And is degraded by aerobic bacteria grown in the workpiece. Although the amount of the object to be processed decreases with the passage of time by the amount of solid organic matter gasified by this decomposition action and the amount of water evaporated from the surface of the object to be processed, the undecomposed object to be processed each time the flush toilet 4 is used. Therefore, depending on the frequency of use of the flush toilet 4, the water level (storage amount) of the object to be treated in the treatment tank 1 gradually increases. And if the water level of the to-be-processed object in the processing tank 1 reaches the set maximum water level H, a warning lamp will light, subsequent use of the flush toilet 4 will be stopped, and the water level of the to-be-processed object in the processing tank 1 will be the highest. When the water level falls below H, the use of the flush toilet 4 is resumed.

  In the treatment tank 1 as described above, the stored object to be treated is decomposed by the effects of heating, stirring, and aeration as is well known, but until the solid organic matter is completely decomposed until it is completely decomposed. Rather than the batch process of leaving the required time and replacing the undecomposed object after the decomposition is completed, the undecomposed object is added each time the flush toilet 4 is used as described above. Depending on the frequency of use, undecomposed solid organic matter is mixed in the object to be treated in the treatment tank 1. Thus, the solid organic matter in the object to be treated is subjected to the above-mentioned heating, stirring, and aeration, and as the decomposition proceeds, fine granular or flake-like light decomposition residues with a specific gravity are generated. The surface layer of the processed material is in a floating state. On the other hand, outside air is sent along the one side wall of the processing tank 1 from the air blower 49 that is constantly operating into the space above the object to be processed in the processing tank 1, and at the same time, in the space above the object to be processed The exhaust blower 51, which is always in operation, from the exhaust pipe 50 located on the opposite side of the air supply port (opening of the elbow pipe 48) from the air supply blower 49 into the treatment tank 1 Since it is sucked and discharged out of the tank, a horizontal rotating air flow is always formed in the upper space of the object to be processed due to the fresh air taken in. At this time, the exhaust blower 51 has a higher exhaust capacity than the air supply blower 49, and therefore the space above the object to be processed is in a slightly negative pressure state from the atmospheric pressure. For these reasons, the diffusion of decomposition product gas from the surface of the object to be processed and the evaporation of moisture are performed at the same time, and at the same time, the surface layer of the object to be processed receives a horizontal turning force by the horizontal rotating airflow, The to-be-processed object in the processing tank 1 will turn horizontally in the same direction as the said horizontal rotation airflow. This horizontal swiveling of the object to be processed also causes the decomposition residue floating on the surface layer of the object to be processed to collect to a certain size and promotes the stirring of the object to be processed. Is done well.

  As described above, the residue having a low specific gravity floating on the surface layer of the object to be processed flows along the peripheral wall in the processing tank 1 by the horizontal swirling flow of the surface layer of the object to be processed. Even if it occurs in the area 6, the opportunity to flow through the surface layer of the workpiece in the residue discharge area 5 is given. On the other hand, the residue discharging means 16 is automatically operated for a set time at a set time (including day unit) interval. That is, the motor 23 with a speed reducer is operated, and the rotary arm 17 is rotated in a predetermined direction at a predetermined speed via the small-diameter spur gear 22 and the large-diameter spur gear 21, thereby pumping out residues at both ends of the rotary arm 17. When the bucket 19 is rotated along the vertical rotation circulation path, the bucket 19 rotates in the workpiece in the residue discharge area 5 in the lower end region of the vertical rotation circulation path. At this time, since the bucket 19 rotates via the vicinity of the bottom of the processing tank 1 lower than the lowest water level L of the object to be processed, the bucket 19 reliably rotates in the object to be processed regardless of the water level of the object to be processed. Can do.

  Thus, when each bucket 19 rotates in the object to be processed in the residue discharge area 5 and then escapes upward from the object to be processed, the decomposition residue floating on the surface layer of the object to be processed together with sewage It will be pumped out. In order to efficiently pump out the floating decomposition residue by the bucket 19, at least a part of the bucket 19 can have a mesh structure capable of draining water. Further, immediately after entering the workpiece, the bucket 19 is swung around the support shaft 24 by the frictional resistance with the workpiece, so that the vicinity of the bottom of the treatment tank 1 in the residue discharge area 5 is obtained. Although it is conceivable to rotate in a pumping posture, even if it is so, the residue discharge area 5 is located farthest from the hydrolyzed urine receiving port 3 of the processing tank 1 and a net for receiving coarse foreign substances is located in the middle. 14 is present, it is unlikely that undecomposed coarse organic matter having a relatively higher specific gravity than the decomposition residue and tending to settle at the bottom will be pumped out by the bucket 19. In addition, when making the mesh structure which can drain water at least one part of the bucket 19 as mentioned above, the surrounding wall upper part of the bucket 19 is made into the mesh structure which can drain water so that a certain amount of dirty water can be pumped out together. Conversely, in order to reduce the pumping of sewage as much as possible, the lower part of the peripheral wall of the bucket 19 or the entire peripheral wall may have a mesh structure capable of draining water.

  The bucket 19 from which the decomposition residue and sewage have been pumped is kept upright by gravity and rotates upward in the vertical rotation circulation path. As shown in FIG. 7, this bucket 19 is positioned at the highest position in the vertical rotation circulation path. When rotating (residue discharge position), the pin-shaped fixed contact member 26 contacts the contacted member 25 on the bucket 19 side, so that the contacted member 25 moves under the fixed contact member 26. The bucket 19 rotates around the support shaft 24 until it goes through, and is automatically converted from an upright posture to a content discharging posture. Therefore, the decomposition residue and sewage pumped out by the bucket 19 are automatically discharged into a discharge residue receiving hopper 20 provided immediately below the highest position (residue discharge position) of the vertical rotation circulation path of the bucket 19. Is done.

  As shown in FIGS. 5 to 7, the residue processing means 28 provided on the lower side of the discharge residue receiving hopper 20 includes three circumferential spaces A <b> 1 to A <b> 3 formed between the radial partition walls 37 a to 37 c of the rotating body 30. Among the A3, two partition spaces, for example, the partition spaces A1 and A2 are located in the residue temporary storage portion P1 and the residue drying portion P2 in the fixed case 29, and the remaining one partition space A3 is outside the fixed case 29. It waits in the state located in dry residue discharge position P3. That is, the residue processing means 28 stands by in a state where the three partition spaces A1 to A3 are assigned to three positions, that is, the residue temporary storage part P1, the residue drying part P2, and the dry residue discharge position P3. Accordingly, the residue and sewage discharged to the discharge residue receiving hopper 20 are directly above the opening 44 of the fixed case top plate 33 and the partition space A1 located in the residue temporary storage part P1 from the hopper 20 and the opening 44. Is introduced into the partition space A1 through the residue receiving opening 43a of the large-diameter spur gear 40 that is directly underneath. Since the partition space A1 is surrounded by the radial partition walls 37a and 37c, the drain region 34a of the fixed case bottom plate 34, and the drain region 32a of the fixed case peripheral side plate 32, the partition space A1 (residual temporary storage) Moisture is naturally discharged from the residue and sewage introduced into the part P1) and returned to the residue discharge area 5 in the treatment tank 1 immediately below the residue.

  Since the amount of residue pumped out by one residue pumping bucket 19 is small, the rotary arm 17 of the residue discharging means 16 is rotated continuously for a set time or intermittently at a set time interval, and pumped during that time. The residue to be discharged is stored in the partition space A1 in the residue temporary storage part P1 of the residue processing means 28, and drained, but undecomposed organic matter pumped together at this time is sewage pumped out later Due to the action of bacteria having abundant decomposition ability existing in the inside, the decomposition process is performed while being stored in the compartment space A1 of the temporary residue storage part P1. Then, when the set amount of time has passed and the amount of draining residue in the partition space A1 in the residue temporary storage part P1 reaches a predetermined amount, the rotation driving of the rotary arm 17 of the residue discharging means 16 is stopped, and then the residue processing means The 28 rotating bodies 30 are rotationally driven in a predetermined direction by a predetermined angle.

  That is, the motor 42 with a speed reducer of the rotation driving means 31 is operated, the rotating body 30 is removed via the small diameter spur gear 41 and the large diameter spur gear 40, and the partition space A1 of the residue temporary storage portion P1 is dried on the lower side. It is rotated by an angle (120 degrees) between the radial partition walls 37a to 37c in the direction of moving to the part P2, and stopped. As a result, the storage residue in the partition space A1 surrounded by the radial partition walls 37a, 37c, the fixed case bottom plate 34, and the fixed case peripheral side plate 32 is pushed by the radial partition wall 37c, and the residue drying on the lower side is performed together with the partition space A1. Sent to the part P2. At the same time, the partition space A2 located in the residue drying section P2 is moved to the lower dry residue discharge position P3, and the empty partition space A3 waiting on the upper side of the residue temporary storage section P1 is temporarily removed. It will be moved to the storage part P1.

  By operating the residue discharge means 16, the first process of pumping the decomposition residue from the processing tank 1 and storing it in the residue temporary storage part P <b> 1 of the residue process means 28 and draining it, and the first process is executed for a set time. After that, the second process of moving the draining residue in the residue temporary storage part P1 to the lower residue drying part P2 is automatically and repeatedly executed by the operation of the rotating body 30 as the residue conveying means of the residue processing means 28. Accordingly, during the execution of the first step, the draining residue transferred to the residue drying unit P2 is left to dry. In this embodiment, the residue drying part P2 is formed by one of the partition spaces A1 to A3 including the drain region 34a of the fixed case bottom plate 34 for draining and the drain region 32a of the fixed case peripheral side plate 32. Therefore, even if there is residual moisture, it is dropped from the drain regions 32a, 34a and returned to the residue discharge area 5 in the processing tank 1 below, and at the same time, the protruding case portion 15 where the residue drying portion P2 is located. Inside, there is an air flow from the upper space of the object to be processed in the treatment tank 1 to the exhaust pipe 50 via the inside of the protruding case portion 15, so that a part of the air flow passes through the drain regions 32 a and 34 a. Therefore, it is considered that the flow also flows through one of the partition spaces A1 to A3 located in the residue drying part P2, so that it is considered that the draining residue is effectively dried in the residue drying part P2.

  By performing the next second step, one of the partition spaces A1 to A3 located in the residue drying section P2 is moved to the lower residue drying residue discharge position P3. Are automatically discharged. That is, only the radial partition walls 37a to 37c of the rotating body 30 serving as the partition walls in the circumferential direction of the partition spaces A1 to A3 rotate during the second stroke, so that the dry residue in the residue drying part P2 has the partition space at that position. For example, when it is the partition space A1, it is pushed by the partition wall 37c on the rotation rear side of the partition space A1, and is pushed out to an area without the bottom plate 32 of the fixed case 29, that is, the dry residue discharge position P3 and set downward. It is automatically put into the dry residue carrying case 47. Therefore, when a required amount of dry residue is accumulated in the dry residue carrying case 47 by repeating the first stroke and the second stroke, the dry residue is not discharged from the dry residue discharge position P3. During the execution of one stroke, the dry residue carrying case 47 is taken out and the accumulated dry residue is discarded, and the empty dry residue carrying case 47 is disposed below the cover 27, that is, below the dry residue discharge position P3. Set it on the side.

The suction port 60a is at a height at which the object to be treated can be sucked as long as the object to be treated in the treatment tank 1 maintains a water level equal to or higher than the minimum water level L. The object to be processed sucked from 60 a is discharged from the lateral discharge port 59, and a horizontal rotating flow of the object to be processed can be generated in the processing tank 1.

  The pump 55 shown in FIGS. 10 and 11 is a submersible pump. In the illustrated example, the submersible pump 55 is disposed on the bottom plate 1c of the treatment tank 1 and inside the circular protective pipe 9 in which the heater wire of the heating means 7 is installed.
