Description
Technical Field
The present invention relates to a drainage device, and more particularly, to cleaning a cross pipe from which drainage water flows out of a drainage channel.
Background
For example, drainage from a restaurant entering a building such as a shopping mall is sent from a drainage pipe in the store to a vertical pipe (main pipe) of the shopping mall through a drainage trough and a drainage lateral pipe, and then discharged to the outside.
However, in restaurants in which grease is used relatively frequently, the possibility of clogging of the lateral drain branch pipe is relatively high. In addition, when the clogging degree is severe, there is a case where the drain water flowing out from the drain tank to the drain lateral branch pipe flows back without being discharged from the stand pipe, and the inside of the store is submerged. In order to eliminate such a situation, it is necessary to perform cleaning before clogging of the lateral drain pipes becomes serious.

Problems to be solved by the invention
However, since the lateral drainage pipe is buried in a floor of a building or the like, it cannot be easily cleaned. Further, although it is conceivable to perform cleaning periodically, since the clogging is different depending on the store, if the clogging is not so large, the cleaning work becomes useless, and the cleaning cost is wasted. On the other hand, if the interval between cleaning operations is excessively increased, the drain water flows back as described above.
The invention aims to prevent a horizontal pipe connected with a drainage groove from being blocked as much as possible by using compressed air.

Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Hereinafter, the structure of the drainage device in the present embodiment will be described with reference to the drawings.
The drain device in the present embodiment constitutes a part of drain piping equipment installed in a building such as a shopping mall. In the drain tank 1 constituting a main part of the drain apparatus of the present embodiment, drain discharged from a drain facility of a restaurant in a shopping mall, for example, flows in from the drain inlet 2 through a miscellaneous drain pipe (not shown). The drain water discharged from the drain device is assumed to be drain water discharged from a drain port of a sink or a floor in a kitchen. Drainage may contain oils and fats, food residues, powder, and the like (hereinafter, collectively referred to as "oils and fats") which cause clogging of a drainage pipe. By making the water level of the drain in the drain tank 1 higher than the lower surface of the drain pipe 4, the drain 3 stored in the drain tank 1 automatically flows out to the lateral drain branch pipe 5 through the drain pipe 4. The drain water flowing out to the horizontal drain pipe 5 is discharged to the outside through a vertical pipe (not shown).
The drain tank 1 in the present embodiment has a structure divided into two layers of an upper portion 1a and a lower portion 1b by a partition 6. The upper part 1a of the drain tank 1 is provided with a drain inlet 2, and the lower part 1b of the drain tank 1 is provided with a drain pipe 4. Also, as shown in fig. 1, at least the side wall of the lower portion 1b is formed of a double-layered structure of an outer wall and an inner wall. A compressed air storage portion 7 for storing compressed air is formed between the outer wall and the inner wall of the lower portion 1b of the drain tank 1. The partition plate 6 is fixed by being placed on a step formed by the outer wall and the inner wall of the lower portion 1b of the drain tank 1, and partitions the upper portion 1a and the lower portion 1b of the drain tank 1 at a portion other than the opening portion through which the water feed cylinder 12 is fitted.
The air compressed by the compressor 8 is injected into the compressed air storage 7 through the high-pressure hose 9 and the connection port 10 provided in the outer wall of the lower portion 1b of the drain tank 1. When compressed air of a predetermined pressure is injected, the connection port 10 is closed. The compressed air storage unit 7 is provided with a pressure sensor 11 for measuring the air pressure.
An opening is formed in the vicinity of the substantially center of the separator 6. By fitting and passing through the opening, a water passage tube 12 is disposed to communicate the upper portion 1a and the lower portion 1b of the drain tank 1. The water passage tube 12 has a hollow shape, and allows the drain water flowing from the drain inlet 2 into the upper portion 1a of the drain tank 1 to flow into the lower portion 1b of the drain tank 1. However, the upper end surface of the water passage cylinder 12 is blocked by the ceiling plate so that the dirt mixed in the drain water flowing into the upper portion 1a of the drain tank 1 does not reach the lower portion 1b through the water passage cylinder 12. The side surface of the water passage tube 12 is formed of a net structure having small meshes. Thus, the dirt mixed in the drain from the drain inlet 2 stays in the upper portion 1a of the drain tank 1 and is appropriately removed. The drainage water containing no dirt enters the inside from the meshes on the side surfaces of the water passage tube 12 in the upper portion 1a of the drainage channel 1, is conveyed to the lower portion 1b of the drainage channel 1, and flows out from the meshes to the outside. Thus, the drain flowing into the upper portion 1a of the drain tank 1 from the drain inlet 2 is transported to the lower portion 1b of the drain tank 1 and then stored. Thus, the lower portion 1b of the drain tank 1 forms a drain reservoir 13. In the following description, the lower portion 1b of the drain tank 1 and the drain reservoir 13 have the same configuration.
A float switch 14 is provided inside the water passage tube 12, and the float switch 14 moves up and down in the drain reservoir 13 in accordance with the water level of the drain 3 stored in the drain reservoir 13 of the drain tank 1. The structure of the float switch 14 will be described later.
A valve 15 is provided on the inner wall of the drain tank 1. When the water level of the drain 3 in the lower portion 1b of the drain tank 1 (i.e., the drain reservoir 13) reaches a predetermined height, the valve 15 is controlled to open, whereby the compressed air stored in the compressed air reservoir 7 is discharged to the drain reservoir 13. Further, when the air pressure in the drain storage portion 13 becomes equal to or lower than a predetermined threshold value, the valve 15 is closed.
A safety valve 16 is also provided on the inner wall of the drain tank 1. When the air pressure in the compressed air storage 7 rises to an abnormal value, the safety valve 16 releases the compressed air to the drain storage 13. Similarly, a safety valve 17 is provided in the partition plate 6, and when the air pressure in the drain reservoir 13 rises to a value indicating an abnormal state, the safety valve 17 releases the compressed air in the drain reservoir 13 to the upper portion 1a of the drain tank 1. Further, a pressure sensor 18 for measuring the air pressure in the drain storage portion 13 is provided on the bottom surface of the partition plate 6.
The partition plate 6 is further provided with a window 19 which can be opened and closed from the upper side of the drain tank 1. The window 19 is firmly closed to such an extent that it is not opened even if the compressed air is injected into the lower portion 1b of the drain tank 1, and the compressed air does not leak to the upper portion 1a of the drain tank 1. The window 19 has a size that allows a human hand to enter, and is provided for the purpose of cleaning the lower portion 1b of the drain tank 1.
The drain storage portion 13 is provided with a water level sensor 20 for detecting the water level of the stored drain 3. A water storage portion 21 is provided at the bottom of the drain tank 1, and an inlet of the drain pipe 4 is disposed in the water storage portion 21. The flow outlet side tip 22 of the drain pipe 4 is formed by a cylindrical tip shape.
Next, a description will be given of a configuration of the blocking mechanism of the present embodiment including the float switch 14 and the float switch engaging portion 30.
As described above, the float switch 14 moves up and down inside the water passage tube 12 in accordance with the water level of the drain water 3 stored in the drain storage portion 13, and has the plate-shaped main body portion 25, and the main body portion 25 corresponds to a float for floating on the drain water 3. A starting contact 26 and a check cover 27 corresponding to a movable contact of the electromagnetic switch are provided on the upper surface of the main body 25.
The float switch engaging portion 30 facing the float switch 14 is attached to the inside of the water passage tube 12 at the height of the partition plate 6. The float opening Guan Kage portion 30 is annular, and in a normal state, the drain water flowing into the upper portion 1a of the drain tank 1 is sent to the lower portion 1b of the drain tank 1 through the hole 31a of the ring 31. An electromagnet 32 and a fixed contact 33 of the electromagnetic switch are provided on a surface of the ring 31 facing the float switch 14. The electromagnet 32 holds the float switch 14 reaching a predetermined height by an electromagnetic force under the control of the control device 40. In order to hold the float switch 14, at least the position of the main body 25 facing the electromagnet 32 needs to be formed of a magnetic material. For example, the main body 25 may be formed of a magnetic material, or a magnetic material may be disposed at a position facing the electromagnet 32. In fig. 4, an example in which the electromagnet 32 is provided only at the position 1 is schematically shown, but a plurality of electromagnets 32 may be provided in order to improve the holding force. When the float switch 14 is held, the hole 31a of the ring 31 of the float switch engaging portion 30 is closed by the check cover 27, and the space between the lower portion 1b and the upper portion 1a of the drain tank 1 is blocked by the partition plate 6 and the check cover 27. Thus, even if compressed air is injected into the lower portion 1b of the drain 3 stored in the lower portion 1b of the drain tank 1, the compressed air does not leak to the upper portion 1a of the drain tank 1.
As described above, the float switch 14 moves up and down in the water passage tube 12, and in order to smoothly move up and down, the guide 34 having a chevron shape is provided on the inner surface of the water passage tube 12 from the lower end to the float switch engaging portion 30. In the present embodiment, the water passage pipe 12 is provided at a position facing the inner surface thereof. A notch 28 is provided at a position where the float switch 14 engages with the guide 34. In order to easily understand the positional relationship of the guide 34 with the notch 28, the guide 34 is shown in fig. 4.
As described above, the drainage device includes a structure that operates by control and a structure that involves input and output. The control device 40 is electrically connected to these components, or is communicably connected by wire or wireless, and performs operation control and data input/output. Specifically, the control device 40 controls the delivery of compressed air from the compressor 8, controls the opening and closing of the connection port 10 and the valve 15, and controls the operation of the electromagnet 32. The control device 40 acquires pressure values measured by the pressure sensors 11 and 18, data of the water level detected by the water level sensor 20, and a signal generated by the contact of the fixed contact 33 of the electromagnetic switch with the starting contact 26.
The control device 40 is a controller including a storage unit such as a CPU, ROM, RAM, hard Disk Drive (HDD), and a network interface. The control of the above-described configuration and the input/output for signal reception are performed by hardware or software.
Next, a drainage control process of the drainage 3 stored in the drainage tank 1 in the present embodiment will be described with reference to a flowchart shown in fig. 5.
First, in order to operate the drain device in the present embodiment correctly, compressed air of a predetermined air pressure needs to be injected into the compressed air storage unit 7 by the compressor 8. Therefore, the controller 40 controls the opening of the connection port 10 to supply the compressed air from the compressor 8 to the compressed air storage 7 for filling (step 101).
Drain water discharged from a drain facility or the like of a restaurant flows into the upper portion 1a of the drain tank 1 from the drain inlet 2. The inflowing drain water enters the inside of the water passage tube 12 through the mesh openings and flows into the lower portion 1b (drain reservoir 13) of the drain tank 1. At this time, the dirt mixed in the drain water is retained in the upper portion 1a of the drain tank 1 by the water passage tube 12.
The drain 3 flowing into the drain reservoir 13 gradually accumulates to raise the water level. The float switch 14 moves upward as the water level of the drain 3 rises. The water level passing through the drain 3 exceeds the lower surface of the drain pipe 4, and thus automatically flows out to the drain lateral pipe 5 through the drain pipe 4. The water level of the drain 3 rises and falls by flowing out from the drain lateral pipe 5 before reaching a prescribed height (no in step 102).
However, when the inflow amount from the drain inlet 2 exceeds the outflow amount from the drain lateral pipe 5, the accumulated amount increases in the drain accumulating portion 13, and the water level of the drain 3 rises. Even if the drain flows out from the drain lateral pipe 5, the water level of the drain 3 continues to rise when the inflow amount from the drain inlet 2 is large. When the water level of the drain 3 reaches the predetermined height (yes in step 102), the float switch 14 also reaches the predetermined height, and at this time, the starting contact 26 of the float switch 14 comes into contact with the fixed contact 33 of the electromagnetic switch of the float switch engaging portion 30. By bringing the fixed contact 33 of the electromagnetic switch into contact with the starting contact 26, an ON (ON) signal is transmitted to the control device 40.
In a state where the fixed contact 33 of the electromagnetic switch is in contact with the starting contact 26, the check cover 27 of the float switch 14 enters the hole 31a of the ring 31 of the float switch engaging portion 30 and is in a closed state. That is, the lower portion 1b of the drain tank 1 is blocked from the upper portion 1a.
The controller 40 receives an on signal from the fixed contact 33 of the electromagnetic switch, and detects that the drain water 3 stored in the drain water storage portion 13 has reached a predetermined height.
At this time, the control device 40 energizes the electromagnet 32. The electromagnet 32 holds (locks) the float switch 14 by an electromagnetic force when energized (step 103). Thus, the lower portion 1b of the drain tank 1 is reliably blocked from the upper portion 1a regardless of the vertical movement of the water surface of the drain 3. Fig. 6 shows a state in which the check cover 27 of the float switch 14 blocks the hole 31a of the ring 31 of the float switch engaging portion 30, and the lower portion 1b and the upper portion 1a of the drain tank 1 are blocked.
As described above, the "predetermined height" in the present embodiment is a height at which the check cover 27 of the float switch 14 closes the hole 31a of the ring 31 of the float switch engaging portion 30 and the lower portion 1b of the drain tank 1 is in a state of being blocked from the upper portion 1a. As will be described later, the height is the height at the time when the supply of the compressed air to the drain reservoir 13 is started.
Next, when the float switch 14 reaches a predetermined height, the control device 40 controls the valve 15 to open. The valve 15 is opened by the control device 40 to release the compressed air stored in the compressed air storage unit 7 to the drain storage unit 13 (step 104). Since the hole 31a of the ring 31 of the float switch engaging portion 30 is closed by the check cover 27 of the float switch 14 and the drain reservoir 13 is blocked from the upper portion 1a of the drain tank 1, the compressed air acts to press down the water level of the drain 3 stored in the drain reservoir 13 by the air pressure. This causes the drain 3 to pass through the drain pipe 4, which is the only escape route for the drain 3, and to flow out forcibly from the lateral drain branch pipe 5.
The drain 3 flows out from the drain lateral pipe 5, and the water level of the drain 3 stored in the drain storage portion 13 is lowered. The float switch 14 is originally raised or lowered in accordance with the water level of the drain 3, but is locked by the electromagnet 32 and therefore does not lower. That is, at this time, since the hole 31a of the ring 31 is closed, the drain does not flow into the drain reservoir 13 from the upper portion 1a of the drain tank 1. Therefore, the water level of the drain 3 stored in the drain storage portion 13 does not rise.
The space in the drain reservoir 13 is expanded by the decrease in the water level of the drain 3, and the air pressure in the drain reservoir 13 is continuously decreased to a predetermined threshold value or less (no in step 105). The predetermined threshold value may be a predetermined numerical value or may be an air pressure that is equal to the air pressure in the compressed air storage 7 and thus does not obtain the water level depression effect of the drain 3 to a great extent.
When the air pressure in the drain storage portion 13 is reduced to a predetermined threshold value or less (yes in step 105), the control device 40 stops the energization of the electromagnet 32. Thereby, the electromagnet 32 unlocks the float switch 14 (step 106). Thereby, the float switch 14 drops to the water surface of the drain 3 by its own weight.
Further, the control device 40 controls the valve 15 to be closed, thereby stopping the supply of the compressed air from the compressed air storage unit 7 to the drain storage unit 13 (step 107).
Next, the process returns to step 101, and the controller 40 controls the opening of the connection port 10 and supplies compressed air from the compressor 8 to the compressed air storage 7 for the next drainage control to perform filling (step 101). When a predetermined amount or a predetermined air pressure of compressed air is injected into the compressed air storage unit 7, the control device 40 controls the connection port 10 to close.
In the present embodiment, as described above, the drain water 3 stored in the drain tank 1 is forcibly discharged by the compressed air, and the clogging of the lateral drain pipe 5 is prevented by the momentum of the forcibly discharged drain water 3.
First, by vigorously flowing the drain 3 out of the drain pipe 4, grease contained in the drain 3 is less likely to adhere to the lateral drain branch pipe 5. In particular, in the present embodiment, the outlet-side tip 22 of the drain pipe 4 is formed in a cylindrical shape, so that the flow velocity can be increased. For example, the drain 3 from the flow outlet side tip 22 is discharged straight, that is, slightly upward in a direction parallel to the inner surface of the lateral drain pipe 5 or in consideration of gravity, so that the drain 3 does not come into contact with the lateral drain pipe 5 as much as possible but enters the vertical pipe at once. That is, clogging is prevented so that the drain 3 does not contact the lateral drain pipe 5.
Alternatively, the drain water 3 from the outlet-side tip 22 may be discharged vigorously toward the bottom surface of the lateral drain pipe 5. This allows grease that may adhere to the lateral drain branch pipe 5 to be scraped off by the drain 3 that has flowed out vigorously. Further, the outflow direction from the outflow side tip 22 may be controlled by the control device 40.
As described above, in the present embodiment, the air pressure of the compressed air is used to strongly discharge the drain water from the outlet-side front end 22 of the drain pipe 4 to the vertical pipe, so that the dirt does not adhere to the lateral drain pipe 5. Alternatively, the dirt attached to the inner surface of the drainage lateral pipe 5 is washed away by the momentum of the drainage. This can prevent the inner surface of the lateral drain pipe 5 from being contaminated, and therefore can reduce the cost required for cleaning the lateral drain pipe 5.
In the present embodiment, the operation is as described above, but in order to effectively utilize the air pressure of the compressed air, the relationship between the size of the drain storage portion 13 and the air pressure of the compressed air fed into the drain storage portion 13 becomes an important element. Therefore, the installation height of the partition plate 6, the air pressure and the capacity of the compressed air (the air pressure of the compressed air stored in the compressed air storage unit 7 and the size of the compressed air storage unit 7) are preferably determined in consideration of the size of the drain tank 1, the height of the drain pipe 4, and the like.
The air pressure supplied to the drain storage portion 13 can be realized by the following air pressure adjusting function. For example, the control device 40 adjusts the air pressure of the compressed air fed to the compressed air storage 7. Alternatively, the control device 40 adjusts the opening degree of the valve 15 to adjust the air pressure of the compressed air discharged from the compressed air storage unit 7 to the drain storage unit 13.
In the present embodiment, the starting contact 26 of the float switch 14 is brought into contact with the fixed contact 33 of the electromagnetic switch of the float switch engaging portion 30, whereby a predetermined height of the water level of the drain 3, which is a trigger for sending the compressed air from the compressed air storage portion 7 to the drain storage portion 13, is detected. However, the timing of feeding the compressed air from the compressed air storage 7 to the drain storage 13 may be obtained by the water level detected by the water level sensor 20.
In the present embodiment, the float switch engaging portion 30 releases the float switch 14 when the air pressure in the drain storage portion 13 is equal to or less than a predetermined threshold value, but the float switch engaging portion 30 may release the float switch 14 in accordance with the water level detected by the water level sensor 20.
In the present embodiment, the compressed air is temporarily stored in the compressed air storage unit 7 and then sent to the drain storage unit 13. This is a case in which the supply of compressed air is delayed in consideration of the case where the compressor 8 is connected to the plurality of water discharge tanks 1. As long as such a problem does not occur, the compressed air may be directly sent from the compressor 8 to the drain storage portion 13 without providing the compressed air storage portion 7.
In the present embodiment, the window 19 is provided to facilitate cleaning of the lower portion 1b of the drain tank 1. The cleaner may throw ice cubes from the window 19 in order to clean the lateral drain pipe 5. If the compressed air is combined with the ice cubes, the lateral drain 5 can be cleaned more effectively.
