Description

Technical Field

[0001] The invention relates to the technical field of vacuum toilets, in particular to a marine intelligent vacuum toilet and a use method thereof. Background Art

[0002] Warships and other ships sail at sea for a long time, and often need to install vacuum toilets with water-saving functions for crew excretion. A vacuum toilet creates a vacuum in the entire system. Each toilet in the system must be isolated from the system by an isolation valve. When flushing the toilet, open this valve and rely on the pressure difference with the atmospheric pressure to take away the contents of the toilet. An ordinary toilet consumes 6 liters of water per flush, while a vacuum toilet only consumes 0.6-0.8 liters; it can also separate urine and feces, and the feces are directly sent to the fertilizer factory to be made into organic fertilizer. The vacuum system is maintained by the automatic operation of the vacuum pump.

[0003] For large ships sailing on the ocean for a long time, the excrement in the toilet cannot be discharged directly into the sea, because the germs carried in human excrement are often very feared by marine life. Therefore, the excrement after flushing the toilet cannot be directly discharged into the sea. Generally, a urine and feces collection box is set up for collection. However, the excrement will produce methane. If it is not stored properly, it will not only cause serious impact on the ship, but also cause a series of explosion accidents if the methane accidentally touches the fire source.

[0004] The prior art ship waste treatment integrated device generally sets up a large storage tank to store all the waste in a centralized manner, and treats it uniformly after accumulating to a certain amount. However, a large amount of waste accumulates in the storage tank and is not treated in time, which also poses a very large safety hazard. In addition, in order to save water, the prior art vacuum toilet does not flush the inner wall of the toilet enough, which makes the later cleaning of the toilet more troublesome. However, using too much water will cause the total amount of waste to increase too quickly, increasing the operating burden of the comprehensive waste treatment system, and is not suitable for ships. Summary of the invention

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a marine intelligent vacuum toilet, which optimizes the excrement treatment device on the ship and reduces the energy consumption of water and treatment equipment by setting wall-wetting return water and large and small collection boxes.

The capacity sensing unit is electrically connected to the ship's comprehensive excrement treatment device for the ship to provide feedback on the amount of excrement in the feces and urine collection box.

[0008] As a further configuration of the above scheme, the urine and feces collection box is also provided with a solid-liquid separation component and a pressure relief valve. The solid-liquid separation component includes a separation net box and a driving unit for controlling the flipping of the separation net box. The driving unit and the pressure relief valve are connected to the vacuum toilet controller. The pressure relief valve is used to open and close the air intake and exhaust channels of the urine and feces collection box.

[0009] As a further configuration of the above scheme, a water level sensor is further provided in the urine and feces collection box below the solid-liquid separation component, and the water tank component is also provided with a sub-compartment, which is located below the water tank. A return pump and a second actuator are provided in the sub-compartment, and the return pump is connected to the urine and feces collection box to extract water from the urine and feces collection box for flushing, and the second actuator controls the pipeline channel of the sub-compartment connected to the flushing pipe.

[0010] As a further configuration of the above scheme, the drainage actuator of the flushing pipe includes a first water outlet and a second water outlet, the first water outlet is used for drainage when the barrel wall is moistened, and the second water outlet is used for drainage for flushing.

[0011] As a further configuration of the above scheme, the barrel ring and the sensing device on the barrel cover are arranged relative to each other, and the sensing device on the barrel cover is used to feedback a signal to trigger the drainage actuator to open the first water outlet, and the second water outlet is connected to the auxiliary compartment.

The mounting seat and the mounting frame are both provided with bolts to be fixedly connected and installed on the mounting surface, and the mounting frame includes a fixed foot and a telescopic frame.

[0013] According to the above-mentioned method for using a marine intelligent vacuum toilet, the following steps are included:

[0014] S1: The vacuum toilet controller is located in the sensing device unit set on the lid. When the lid is flipped up, the drainage actuator opens the first water outlet to drain the water and moisten the wall. The drainage actuator releases water for 1.3 seconds and closes the first water outlet to stop the water discharge.

[0015] S2: While the vacuum toilet controller controls the drainage actuator to moisten the wall, the electromagnetic three-way valve works, switching the branch pipe to connect with the water inlet pipe, and then the water pump starts. The water in the water tank flows into the barrel body to moisten the wall, and then concentrates into the U-shaped pipe part and is pumped back to the water tank by the water pump;

[0016] S3: After the user sits down, the sensor device on the barrel ring feeds back a signal, the electromagnetic three-way valve resets, the water level sensor in the water tank feeds back a signal, and the water pump continues to pump water from the water pipe, and stops when the water level reaches the standard;

[0017] S4: When the sensing device on the barrel ring feeds back a signal, the water level sensor in the urine and feces collection box feeds back a signal to confirm that there is water in the urine and feces collection box, and the return water pump in the auxiliary chamber starts to extract the water separated by the solid-liquid separation component to the auxiliary chamber for flushing;

[0018] S5: After the user has finished using the toilet, the user stands up and the sensing device on the toilet ring feeds back a signal to the vacuum toilet controller, which then controls the second actuator to use the return water in the auxiliary chamber to drain and flush the toilet;

[0019] S6: The second actuator of the auxiliary chamber drains water. After 3 seconds, the auxiliary chamber is drained. The drainage actuator of the water tank is activated, and the second water outlet is opened. The water in the water tank enters the auxiliary chamber, and then enters the flushing pipe through the second actuator and is flushed into the barrel body.

[0020] S7: When the flushing is started in step S5, the actuator of the vacuum assembly is controlled to start to draw away the excrement and flushing water, and store them in the urine and feces collection box until the flushing is stopped in step S6;

[0021] S8: A solid-liquid separation component is set in the feces and urine collection box to separate the solid and liquid excreta and temporarily store them. When several capacity sensing units sense that the total storage volume has reached a threshold value or a single feces and urine collection box has reached a threshold value, the solid-liquid separation component starts to flip over, pouring the solid excreta into the liquid for mixing, and the pressure relief valve of the feces and urine collection box opens;

[0022] S9: Subsequently, the vacuum actuator of the ship's excrement comprehensive treatment device is started to transport the excrement in all the feces and urine collection boxes or the excrement in a single feces and urine collection box that has reached a threshold value to the ship's excrement comprehensive treatment device for comprehensive excrement treatment.

[0023] In summary, the present invention mainly has the following beneficial effects:

[0024] 1. The intelligent vacuum toilet combines the advantages of the vacuum toilet. The backwater and sewage reuse settings not only meet the large amount of water use, but also avoid the increase in the total amount of sewage. The sewage flushing combined with vacuum suction can also absorb the odor at the same time, which can also avoid the smell problem of sewage use. After the sewage flushing, it is also rinsed with cleaner water to keep the barrel and pipes clean;

[0025] 2. The setting of urine and feces collection boxes can not only separate sewage for flushing, but also alleviate the centralized storage problem of ship excrement comprehensive treatment devices, reduce the impact and hidden dangers brought by centralization, and treat more excrement at one time;

[0026] The intelligent vacuum toilet of the present invention combines the design of an intelligent toilet and a vacuum toilet. Compared with ordinary toilets, it not only has the design of wall-wetting wastewater recycling and water-saving, and sewage return water reuse. For the toilet itself, the use of wall wetting and a large amount of water can make the barrel wall surface cleaner and easier to clean and maintain, and the vacuum suction characteristics of the vacuum toilet are fully utilized. Even if it is flushed with sewage, the odor will be sucked away by vacuum suction, and it will not affect the toilet environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0034] refer to Figure 1-Figure 4 A marine intelligent vacuum toilet. The vacuum toilet of the present invention comprises a barrel body 1 and a clean barrel assembly 2. The inner barrel wall 10 of the barrel body 1 is in an arc structure. The barrel wall 10 is funnel-shaped as a whole. A plurality of flushing holes are arranged at the highest point for discharging water to form all-round wall moistening and flushing of the barrel wall 10. A sewage pipe 12 is arranged at the lowest depression of the funnel-shaped barrel body 1. Excrement and water are extracted from the barrel body 1 from the sewage pipe 12. The sewage pipe 12 of the barrel body 1 of this embodiment is provided with a U-shaped pipe portion 13. The U-shaped pipe portion 13 is used to block and retain water. The U-shaped pipe portion 13 is similar to the return bend of a common household toilet, but its water storage capacity is slightly larger, which is mainly used for the return of wall moistening water. The toilet of this embodiment is a vacuum toilet. After use, all substances are sucked away by vacuum pressure, and the U-shaped pipe portion 13 will also be emptied after being sucked away.

[0035] Furthermore, the barrel body 1 of the present invention is also provided with a barrel ring 14 and a barrel cover 15. In the present embodiment, the vacuum toilet controller is located on the barrel ring 14 and the barrel cover 15, and a sensing device 16 is provided respectively. The sensing device 16 has multiple functions. At least the present embodiment is temporarily provided with the sensing device 16 that will feedback a lid opening and wall moistening signal ① after the barrel cover 15 is opened, the sensing device 16 that will feedback a use signal ② when the user sits on the barrel ring 14, and the sensing device 16 that will feedback a use completion signal ③ when the user stands up, so as to realize the vacuum toilet through different The feedback signal triggers different device actions, among which signal ① triggers the water tank 31 to discharge water to wet the barrel wall 10, and the water flows out from the first water outlet 323. If there is no water in the water tank 31, the water pump 34 will first pump water from the water inlet pipe 33 and the water pipe 333, and then drain from the first water outlet 323. Subsequently, the electromagnetic three-way valve 331 switches the water pump 34 to pump the water remaining in the U-shaped tube part 13 from the water inlet pipe 33 and the branch sub-pipe 332 after wetting the wall; signal ② triggers the water pump 34 and the return water pump 39 in the water tank 31 and the auxiliary tank 38, which are used to wet the auxiliary tank 38 and The flushing water of the water tank 31 is filled with water. It is worth noting that there will be a water level detection in the water tank 31 (the conventional design will not be repeated, and it is also used in the above wall-wetting and pumping). If the water level is detected to be sufficient, the pump 34 will not be turned on, and the auxiliary tank 38 is based on the signal fed back by the water level sensor 428 to determine whether to turn on the return pump 39 to replenish the water in the auxiliary tank 38; signal ③ is that the toilet has been used, and it is triggered by the common feedback of the sensing device 16 on the barrel ring 14 and the barrel cover 15. Among them, the sensing device 16 on the barrel ring 14 senses that the user has left the toilet, and the sensing device 16 on the barrel cover 15 senses that the user has left the toilet, and the sensing device 16 on the barrel cover 15 The user senses that the user is away from the toilet. The two work together to prevent people from just getting up temporarily to take paper towels or other operations, and to avoid repeated flushing. When signal ③ is triggered, the second actuator 37 of the auxiliary chamber 38 is opened, and the sewage in the auxiliary chamber 38 is flushed down first. After a delay of 3s, the drainage actuator 321 of the water tank 31 opens the second water outlet 324, and the relatively clean water first flushes into the auxiliary chamber 38, and then flushes down from the auxiliary chamber 38. By the way, the auxiliary chamber 38 that has just been filled with sewage is also flushed. At the same time as signal ③ is triggered, the vacuum actuator is also synchronously started to extract the excrement and sewage in the barrel body 1 and the pipeline;

[0036] like Figure 1The clean barrel assembly 2 of the present invention shown includes a water tank assembly 3 and a vacuum assembly 4, wherein the water tank assembly 3 includes a water tank 31, a flushing pipe 32, a water inlet pipe 33 and a water pump 34 arranged in the water tank 31, the water inlet pipe 33 is provided with an electromagnetic three-way valve 331 and a branch sub-pipe 332 and a water pipe 333 connected to the electromagnetic three-way valve 331, the water pipe 333 is connected to an external water supply pipeline, the branch sub-pipe 332 is connected to the U-shaped pipe portion 13 of the barrel body 1, the water pump 34 is connected to the water inlet pipe 33, the drainage actuator 321 of the flushing pipe 32 for discharging water, the water pump 34, and the electromagnetic three-way valve 331 are all connected to the vacuum toilet controller.

[0037] As a further setting of the above scheme, refer to Figure 3 The vacuum assembly 4 includes an actuator 41, a urine and feces collection box 42 and a capacity sensing unit 44. The urine and feces collection box 42 is used for temporarily storing excrement. The actuator 41 provides power for extracting excrement between the barrel body 1 and the urine and feces collection box 42. The capacity sensing unit 44 is electrically connected to the ship's ship excrement comprehensive treatment device for feedback of the amount of excrement in the urine and feces collection box 42. The capacity sensing unit 44 has two main functions. First, when the excrement + sewage in the urine and feces collection box 42 reaches a threshold, it is fed back to the ship's excrement comprehensive treatment device separately, and the excrement and sewage in the urine and feces collection box 42 are extracted separately. Second, the ship's excrement comprehensive treatment device sends a signal to regularly and uniformly feedback capacity information to the ship's excrement comprehensive treatment device. When the total amount to be processed in all urine and feces collection boxes 42 and the ship's excrement comprehensive treatment device reaches the equipment operation threshold, all vacuum actuators are started at the same time to extract and empty the excrement and sewage in all urine and feces collection boxes 42, and the ship's excrement comprehensive treatment device starts the treatment procedure.

[0038] As a further configuration of the above scheme, the urine and feces collection box 42 is also provided with a solid-liquid separation component 421 and a pressure relief valve 422. The solid-liquid separation component 421 includes a separation net box 423 and a driving unit 424 for controlling the separation net box 423 to flip. The driving unit 424 is as follows: Figure 3As shown, the separation net box 423 can be driven to flip, so that the solid excrement intercepted on the separation net box 423 falls into the sewage below, which is convenient for the vacuum actuator to extract together. When the sewage in the feces and urine collection box 42 reaches the amount that needs to be extracted, the flipped separation net box 423 will be immersed in the sewage. The driving unit 424 and the pressure relief valve 422 are connected to the vacuum toilet controller. The pressure relief valve 422 is used for opening and closing the air intake and exhaust channels of the feces and urine collection box 42. The pressure relief valve 422 is used as an air valve when the actuator 41 of the feces and urine collection box 42 or the vacuum actuator of the ship's excrement comprehensive treatment device is used, and for balancing the pressure in the feces and urine collection box 42, that is, it is also used to balance the pressure changes caused by the production of biogas that may exist in the feces and urine collection box 42.

[0039] As a further configuration of the above scheme, a water level sensor 428 is further provided in the feces and urine collection box 42 below the solid-liquid separation component 421, and the water tank component 3 is also provided with a sub-compartment 38, and the sub-compartment 38 is located below the water tank 31. A return pump 39 and a second actuator 37 are provided in the sub-compartment 38, and the return pump 39 is connected to the feces and urine collection box 42 to extract water from the feces and urine collection box 42 for flushing water, and the second actuator 37 controls the sub-compartment 38 to be connected to the pipeline channel of the flushing pipe 32.

[0040] As a further configuration of the above scheme, the drainage actuator 321 of the flushing pipe 32 includes a first water outlet 323 and a second water outlet 324. The first water outlet 323 is used for draining water when the barrel wall 10 is moistened, and the second water outlet 324 is used for draining water for flushing. The switching of the first water outlet 323 and the second water outlet 324 of the drainage actuator 321 can be carried out by an electromagnet. The switching is formed by different activities of the electromagnet or the activities of the left and right sides to realize the switching and opening of the first water outlet 323 or the second water outlet 324.

[0041] As a further configuration of the above scheme, the barrel ring 14 is arranged opposite to the sensing device 16 on the barrel cover 15. The sensing device 16 on the barrel cover 15 is used to feedback a signal to trigger the drainage actuator 321 to open the first water outlet 323. The second water outlet 324 is connected to the auxiliary chamber 38. The purpose of connecting the auxiliary chamber 38 is as described above. In order to enter the auxiliary chamber 38 first during normal flushing, the sewage residue in the auxiliary chamber 38 can be cleaned to a certain extent. The pipe corresponding to the first water outlet 323 is as follows: Figure 4 As shown, it bypasses the secondary compartment 38 and directly enters the flush pipe 32.

[0042] As a further configuration of the above scheme, a mounting seat 18 is provided at the bottom of the barrel body 1, and the clean barrel assembly 2 is provided with a mounting frame 20. The mounting seat 18 and the mounting frame 20 are both provided with bolts to be fixedly connected and installed on the mounting surface. The mounting frame 20 includes a fixed foot 201 and a telescopic frame 202. The telescopic setting of the mounting frame 20 can facilitate installation and adjustment.

[0043] According to the above-mentioned method for using a marine intelligent vacuum toilet, the following steps are included:

[0044] S1: The vacuum toilet controller is located in the sensing device 16 unit provided on the barrel cover 15. When it is detected that the user flips up the barrel cover 15, the drainage actuator 321 opens the first water outlet 323 to drain water and moisten the walls. Water flows from the water tank 31 through the drainage actuator 321 from the first water outlet 323 directly into the flushing pipe 32, and then is discharged from several flushing holes on the barrel wall 10, flows down along the barrel wall 10 and enters the sewage pipe 12. The drainage actuator 321 drains water for 1.3 seconds, then closes the first water outlet 323, the water tank 31 stops discharging water, and the wall moistening is completed.

[0045] S2: While the vacuum toilet controller controls the drainage actuator 321 to moisten the wall, the vacuum toilet controller synchronously controls the electromagnetic three-way valve 331 to work (generally, it stays in the state where the water pipe 333 is connected to the water inlet pipe 33), switches the branch sub-pipe 332 to be connected to the water inlet pipe 33, and after the switching is completed, the water pump 34 starts to pump water, so that the water in the water tank 31 of step S1 flows into the barrel body 1 to moisten the wall, and then is concentrated in the U-shaped pipe part 13, and the activated water pump 34 pumps it back to the water tank 31. This process step maintains a fixed action and will not be affected by whether the user sits down or closes the barrel cover 15 again;

[0046] S3: After the user sits down, the sensing device 16 on the barrel ring 14 feeds back a signal, the electromagnetic three-way valve 331 is reset, the water inlet pipe 33 is connected to the water pipe 333 again, the water level sensor in the water tank 31 feeds back a signal, and the water pump 34 continues to pump water from the water pipe 333, and stops after the water level reaches the standard (it is worth noting that the continued pumping here has two purposes. One is that when S2 is working, there is no water in the water tank 31, S2 should take an extra step to pump water from the water pipe 333 first, and then the electromagnetic three-way valve 331 is switched to S2 for wall wetting. Second, water is stored in the water tank 31, but the wall wetting consumes part of the water, so that the water does not reach the threshold of the water level sensor. Therefore, it is necessary to continue pumping water and stop when the requirement is met);

[0047] S4: When the sensing device 16 on the barrel ring 14 feeds back a signal, the water level sensor 428 in the urine and feces collection box 42 feeds back a signal to confirm that there is water in the urine and feces collection box 42, and the return water pump 39 in the auxiliary chamber 38 starts to extract the water separated by the solid-liquid separation component 421 to the auxiliary chamber 38 for flushing;

[0048] S5: After the user has finished using the toilet, the user stands up and the sensing device 16 on the toilet ring 14 feeds back a signal to the vacuum toilet controller, which controls the second actuator 37 to use the internal return water auxiliary chamber 38 to drain and flush the toilet;

[0049] S6: The second actuator 37 of the auxiliary chamber 38 drains water. After 3s of drainage, the auxiliary chamber 38 is drained (the capacity is calculated to be drained in 2.5-3s). Subsequently, the drainage actuator 321 of the water tank 31 is started, and the second water outlet 324 is opened. The water in the water tank 31 enters the auxiliary chamber 38, and then enters the flushing pipe 32 through the second actuator 37 and flushes into the barrel body 1 (the drainage actuator 321 here has two sets of flushing schemes, which are mainly executed according to whether there is sewage in the auxiliary chamber 38, that is, whether the auxiliary chamber 38 extracts the main water. If the feedback signal of the water level sensor 428 is used as the basis, the pumping will be performed when there is water, and will not be performed when there is no water. The feedback signal of the water level sensor 428 of this embodiment also triggers a command to the drainage actuator 321. When the feedback signal of the water level sensor 428 indicates that there is water, that is, sewage is replenished in the auxiliary chamber 38, the drainage actuator 321 executes the first set of solutions, and discharges water 3s after the flushing command, and the water discharge time is 3s. When the signal feedback indicates that there is no water, the auxiliary chamber 38 is empty, and the second set of solutions is executed to discharge water for 7s);

[0050] S7: When the flushing is started in step S5, the actuator 41 of the vacuum assembly 4 is controlled to start to draw away the excrement and flushing water, and store them in the feces and urine collection box 42 until the flushing is stopped in step S6;

[0051] S8: A solid-liquid separation component 421 is provided in the feces and urine collection box 42 to separate the solid and liquid excreta and temporarily store them. When a plurality of capacity sensing units 44 sense that the total storage volume has reached a threshold value or a single feces and urine collection box 42 has reached a threshold value, the solid-liquid separation component 421 starts to flip over, pouring the solid excreta into the liquid for mixing, and the pressure relief valve 422 of the feces and urine collection box 42 opens;

[0052] S9: Subsequently, the vacuum actuator of the ship's excrement comprehensive treatment device is started to transport the excrement in all the feces and urine collection boxes 42 or the excrement in a single feces and urine collection box 42 that reaches the threshold to the ship's excrement comprehensive treatment device. When the total amount in the ship's excrement comprehensive treatment device reaches the threshold, the treatment program will be started to carry out comprehensive excrement treatment.

[0053] The marine intelligent vacuum toilet of the present invention takes into account the water use problem on board and the large amount of sewage generated by flushing the toilet, which will increase the workload of the sewage and wastewater treatment equipment on board. Therefore, the whole set of equipment of this embodiment is designed to return water, and the multiple use of water can reduce the total water use and meet the purpose of sufficient flushing of the toilet. The vacuum toilet of the present invention can not only meet the needs of moistening the toilet wall 10 and reducing the adhesion of excrement, but also reduce the use of sewage by setting the wall-wetting water recovery. The recycled wall-wetting water is discharged together with the sewage recovered from the urine and feces collection box 42 when flushing the toilet in the subsequent flushing, which does not affect the water storage problem. In addition, the water tank 31 of this embodiment is set At the rear end of the auxiliary chamber 38, when flushing, cleaner water enters the auxiliary chamber 38 from the water tank 31 and then is flushed away, which can clean the inner wall of the auxiliary chamber 38 to a certain extent, dilute and take away residual sewage. When there is insufficient external water, the equipment can also extract water from the urine and feces collection box 42 to meet the problem of continuous circulation and multiple water use of the toilet. The equipment can not only meet the secondary use of wastewater and reduce the total water volume problem, but also multiple urine and feces collection boxes 42 on the ship are used for distributed temporary storage of excrement, avoiding the concentration of excrement in the treatment tank. On the one hand, it can reduce the total size of the treatment tank, and on the other hand, it can avoid the concentrated but unmet treatment requirements of the treatment equipment in standby, resulting in the fermentation of excrement to produce biogas and other dangerous.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
