Description
Technical Field
The application relates to a hydraulic turbine power suction type closestool, in particular to a hydraulic turbine power suction type closestool which uses tap water as power to drive a hydraulic turbine to realize the mashing suction function.
Background
At present, toilet manufacturers are numerous, the style is various, and common technical defects are four: first, the waste of energy causes the waste of water resources. Tap water is used as both a cleaning agent and an energy source, excrement is flushed through the S bend and enters a sewer, and the required energy is completely from tap water. Bernoulli equation:is an expression of conservation of fluid mechanical energy. If the units of each item in the formula are represented by n/m 3 Rewritten as n.times.m/m 3 (i.e. j/m 3 ) It is found that: wherein the three terms represent the energy density of the three fluid mechanical energies, whereinLet ρgh be the gravitational potential energy density and P be the other potential energy density due to the water pressure. When the tap water gate valve is closed, tap waterThe energy density of (a) is equal to p+pgh, when the pressure P is very high (up to several atmospheres), indicating that the energy density of tap water is very high. P and ρgh can be randomly converted to +.>Becomes an ideal energy source for flushing the toilet. However, almost all toilets today run out of energy almost during the filling of tap water into the tank, leaving only pgh, and h is only the difference in height between the water level in the tank and the S-bend blocking water level. Since the water energy density in the tank is small, a large amount of water must be released to obtain enough energy to flush the stool through the S-bend.
Secondly, the mixing of the clean water and the excrement leads to water resource waste, and the clean water and the excrement are continuously mixed in the process of flushing the closestool, so that the plugging liquid finally remained at the S-bend can only be diluent, and the water consumption of flushing the closestool is required to be large and better when the plugging liquid is close to the clean water.
Thirdly, the S-bend cannot be opened, and once foreign matters are washed into the pipeline and blocked, the S-bend is likely to be unable to be taken out, and finally, the S-bend has to be discarded for updating.
Fourth, it is easy to block. For water saving, a large amount of water is not used for ordinary families endlessly, the dilution degree of the plugging liquid is not high, the S-bend part is scaled continuously over the years and months, the effective water passing cross section is reduced continuously, the water is blocked frequently, the old water is hard to say, and finally the old water is required to be replaced.
Disclosure of Invention
The application aims to overcome the technical defects that the traditional closestool wastes tap water greatly, and the effective service life of the closestool is shortened greatly because the S-bend cannot be opened, foreign matters cannot be blocked in and taken out, and scaling cannot be removed. A power sucking toilet with water turbine is composed of water turbine, propeller and stirring blade, and features that the water turbine is driven by tap water to suck the urine and excrement (diluted by stirring) in S-shaped plug into sewer. The novel toilet bowl can easily crush the stool and send out the S-bend because the energy of tap water is fully utilized. Tap water firstly flows through the water turbine to start the water turbine, then flows into the hollow frame of the closestool and is injected into the bedpan through the small holes. Then at the S-bend, there is formed: the excrement is continuously extracted out of the clear water and continuously follows up in sequence. The mixing of clean water and excrement is fully avoided, so that the water is saved most and the flushing is purified most. The plugging liquid remained at the S-bend part after flushing the closestool is completely clear water, and is not easy to scale. The installation position of the water turbine is an openable position of the S-bend, and even if scaling or foreign matters are blocked in, the water turbine can be cleaned.

The specific embodiment is as follows:
the water turbine according to the application is shown in figures 1, 2, 3 and 4: the shell of the water turbine consists of four parts, namely a volute 11, 21, a bearing retainer 12, a tap water inlet 13, 23, 49 and a volute water outlet 14, 410. Flow velocity v at volute outlet 14, 410 2 Is much smaller than the flow velocity v at the tap water inlet 13, 23, 49 1 . According to the continuity principle v of flow 1 s 1 ＝v 2 s 2 Cross-sectional area s of volute outlet 14, 410 2 Is much larger than the cross-sectional area s of the tap water inlet 13, 23, 49 1 The former is approximately 30 times that of the latter. The impeller enclosed in the volute chamber consists of an impeller chassis 15, an impeller upper cover 16 and blades 17, and the three parts are fixed into a whole. The upper cover 16 can connect the upper parts of all the blades into a whole, effectively prevent the upper parts of the blades from being outwardly stretched due to the centrifugal action in the high-speed rotation, and fully improve the mechanical strength of the impeller. The impeller shafts 18, 31, 413 penetrate through the bearing retainer 12, the upper ends of the impeller shafts extend into the worm chambers 11, 21 to be fixed with the impeller chassis 15 into a whole, the lower ends extend out of the bearing retainer 12, and the upper ends are fixed downwards in sequenceThe propeller 32, 411 and the stirring blade 33, 412 are installed. The tap water inlet ports 13, 23, 49 are connected with the valve body water outlet 65 through hoses. The valve body 64 is opened and tap water is introduced into the volute chambers 11, 21 through the tap water inlet ports 13, 23, 49 to form a high-speed jet. Since the jet enters tangentially, the jet enters the volute 11, 21 immediately before it makes a rotational movement against the inner wall of the volute. Since the aft fluid is continuously injected, this rotating fluid must continuously contract in radius and must pass through the passages defined by all adjacent vanes to reach the middle volute outlet water 14, 410 from the outside and inside. In the process, the water flow continuously interacts with the blades to transfer the kinetic energy of the water flow to the impeller. The maximization of the kinetic energy transfer efficiency between the tap water and the impeller is achieved due to the reasonable design of the shapes of the blades 17 and the impeller upper cover 16 and the apertures of the tap water inlet 13, 23, 49 and the volute water outlet 14, 410. In this embodiment, the turbine may not include the bearing holder.
The lower part of the closestool is provided with an S-shaped bend (a structure which can hold the water shutoff and isolate the odor of the sewer exists at the position of the closestool leading to the sewer) which is different from the traditional closestool, and the whole S-shaped bend is divided into: the S-bend inlet 44, the S-bend propeller position section 45, the S-bend horizontal overflow section 46, 51, the S-bend ampulla carrier 47, 52, the S-bend connecting five parts of the downcomer network section 48. The S-bend propeller stage 45 is a conical tube with a large upper part and a small lower part. The S-bend horizontal overflow path 46, 51 is an inclined circular tube with a horizontal upper opening cut obliquely, and the position of the horizontal upper opening determines the highest water level of the plugging water. The S-bend ampulla connectors 47, 52 are connected between the S-bend horizontal spill flights 46, 51 and the S-bend connecting downcomer network segments 48 with an inner diameter greater than the inner diameter of the S-bend horizontal spill flights 46, 51. Fig. 5 shows a cross-sectional view of the S-curve ampulla receiver 47, 52 of the application along section line B-B.
The upper ports of the S-bend ampulla connectors 47, 52 are provided with members for mounting or dismounting the turbine, so that the ports are opened at the S-bend opening, which is convenient for opening the ports, removing scale from the parts of the toilet, removing foreign matters stuck in the parts, and the like. The turbine wheel shaft 18, 31, 413 extends into the S-bend depth, the lower mounted propeller 32, 411 thereof being located in the S-bend propeller position 45, and the stirring blade 33, 412 being located in the depth of the S-bend inlet 44.
The combined installation of the water turbine, the propeller, the stirring blade and the closestool is shown in fig. 4. The water turbine is arranged at the upper port of the S-shaped ampulla receiving body 47, the volute chamber water outlet 410 is communicated with the water inlet 42 of the hollow frame of the closestool through a hose, and the tap water inlet 49 is communicated with the valve body water outlet 65 at the lower part of the tap water pressure relay energy device through a hose. The impeller shaft 413 extends into the S-bend, the propeller 411 is located at the S-bend propeller position 45, and the stirring blade 412 is located right below the orifice of the stool dilution water injection pipe 43 that opens into the S-bend. The function of the S-bend horizontal spill flight 46 is described as follows: the horizontal overflow section 46 of the S-bend is beveled into an inclined circular tube which closely receives the horizontal upper opening of the section 45 of the S-bend propeller, so that the distance of the propeller 411 for pushing the fecal solution upwards can be sufficiently reduced, because the fecal solution rises with rotation under the action of the propeller, and the fecal solution is thrown into the supporting body 47 of the S-bend ampulla once passing over the section 45 of the S-bend propeller due to the centrifugal effect, and then falls into the section 48 of the S-bend connecting sewer pipe by itself and enters the sewer. After the toilet is flushed, the valve body 64 is closed, the clean water remaining in the hollow frame 41 continues to be injected into the toilet, and the S-bend horizontal overflow section 46 can retain the clean water as the blocking water.
The reason why the S-turn propeller segment 45 is shaped as a conical tube with a small lower part and a large upper part is described as follows: if the S-bend propeller position 45 is formed into a barrel shape with equal height, the suction function of the propeller 411 will depend entirely on the atmospheric pressure (the liquid flowing at the rear end of the propeller forms a low pressure zone during the rotation and the water flow is pressed to follow the liquid at the rear under the action of the atmospheric pressure), and when the water flows at a high speed, the upper edge of the S-bend inlet 44 is exposed to the water surface and air can enter, the suction function of the propeller 411 will be lost, and then the fecal solution in the S-bend will remain. The pumping function is not restored until the clean water injected from the hollow frame 41 reaches the S-bend inlet 44, so that the S-bend inlet 44 is buried again by lifting the liquid surface. In the course of the interruption of this pumping function, the flowing clean water is injected into the stationary fecal solution, and the two are necessarily mixed. Such a mixing process is then repeated, which is disadvantageous in terms of adequate water saving. If the S-bend propeller position section 45 is made into a conical shape with a large upper part and a small lower part as shown in fig. 4, the suction function of the propeller 411 will not depend on the atmospheric pressure completely, under the condition that the S-bend inlet 44 exposes out of the water surface and air can enter, the rotating fecal solution can still continuously rise along the conical surface under the action of centrifugal force, so that the suction effect is not interrupted, and then the clear water reaching the S-bend inlet 44 and the fecal solution in front form sequential follow-up, thereby fully avoiding the mixing of the two and optimizing the water-saving effect.
The application is provided with a stool dilution water injection pipe 43 at the outer side of the toilet bowl at the rear part of the toilet, the upper end of the stool dilution water injection pipe is opened near the water inlet 42 of the hollow frame, and the lower end of the stool dilution water injection pipe is opened above the stirring blades 33 and 412. The action of the stool-diluting water injection pipe 43 is described as follows: after the stool has been crushed and diluted, the propeller 411 can exert a propelling action thereon. When flushing the toilet bowl, the feces need to be mixed in the water and enter the S-bend inlet 44 at the same time, and the stirring blade 412 can effectively stir and dilute the feces. For the case of large discharge amount of dirt, the S-bend inlet 44 is filled with the excrement, and when the toilet is flushed, the water is isolated from the rear and cannot participate in dilution, and the crushed and very viscous excrement is extremely easy to adhere to the propeller 411, so that the propelling effect is reduced or even lost. The stool dilution water injection pipe 43 avoids the blocking of the S-bend inlet 44 to the water involved in dilution, and the water is directly injected from the outside of the toilet bowl to the upper part of the stirring blade 412, thereby solving the problem of the crushing and dilution of the stool very reliably.
In order to fully improve the utilization efficiency of tap water energy, the application is provided with a pressure energy relay device at the joint of a tap water pipe network and a water turbine, and as shown in fig. 6, the pressure energy relay device comprises a pressure tank 61, a water gap cover 62, a tap water pipe network interface 63, a valve body 64 and a valve body water outlet 65. The pressure tank 61 is a vertical tank body with a closed top and an open bottom. The tap water pipe network interface 63 is connected to a tap water pipe network. The valve body water outlet 65 is connected with the tap water inlet 13, 23, 49 of the turbine volute 11, 21 through hoses. The tap water pipe network interface 63 is connected to the tap water pipe network, the valve body 64 is closed, tap water enters the pressure tank 61 from the tap water pipe network interface 63 under the action of strong pressure, and the airtight air in the pressure tank 61 is compressed to makeA significant portion of the energy of the tap water is stored in the tank. The turbine then has a dual energy source: first, a tap water pipe network and second, a pressure tank 61. Taking the second floor of the old community as an example, the valve body 64 is closed, and the pressure of tap water and the pressure of the closed air in the pressure tank 61 are equal to each other, about 0.4 mpa. When the toilet needs to be flushed, the valve body 64 is opened, and P+ρgh is immediately turned onConversion (wherein P is the pressure of a tap water pipe network, ρgh is the potential energy of stored water of the tap water pipe network, v is the flowing speed of tap water), tap water rapidly flows, and the output pressure P of the tap water pipe network immediately drops to below 0.2 megapascals. If the tap water pipe is thin and long, the bending is large, the resistance from the tap water pipe is large, and the output pressure P of the tap water pipe network is reduced to 0.1 megapascals or even lower. This creates conditions for the energy output of the pressure tank 61, and because of the large pressure difference between the inside and outside of the tank, the compressed air in the tank expands rapidly, pushing out the water in the tank rapidly, and the water together with the water directly from the tap water pipe network interface 63 enters the water turbine, so that the water turbine obtains doubled power.
The water mask 62 is a small drum with an upper part closed and side walls provided with openings towards the periphery, the lower opening is communicated with the inlet of the pressure tank 61 and is arranged at the inlet below the pressure tank 61, and the effect of the water mask is to prevent water flow from being sprayed upwards out of the water surface in the tank to interact with air above the tank during water inflow so as to generate bubbles in the water. Under the condition of no water mask, if water is fed and then discharged, bubbles which can not rise out of the water surface are mixed in the water and discharged out of the tank, and the closed air in the tank is reduced gradually over time, so that the energy which can be stored is reduced gradually. In conclusion, the pressure energy relay device is arranged, so that the applicable conditions of the power suction type closestool of the water turbine can be greatly reduced, and the requirements on the resistance of a tap water pipeline and the height of a floor are relaxed. Figure 7 shows a cross-sectional view of the water mask of the pressure relay of the present application along section line C-C.
In summary, the application relates to a power suction type closestool based on a water turbine, wherein the upper part of the closestool is provided with a hollow frame, the hollow frame is provided with fine water injection holes which are uniformly distributed along the periphery towards the inner side of the bedpan, and the rear part of the hollow frame is provided with a water inlet.

The outer side of the toilet bowl at the rear part of the toilet is provided with a stool dilution water injection pipe which is communicated with the deep part of the S-shaped inlet through a hollow frame. The water turbine is arranged at the upper port of the ampulla carrier, and the housing of the water turbine comprises a volute chamber and a bearing retainer. A tap water inlet is tangentially arranged on the side wall of the volute, and a volute water outlet is arranged in the central position of the upper part of the volute. The impeller of the water turbine is sealed in the volute, the impeller rotating shaft penetrates through the bearing retainer, the screw propeller and the stirring blade are sequentially arranged at the lower part of the impeller from top to bottom, and the screw propeller and the stirring blade are respectively positioned under the S-bend screw propeller position section and the orifice of the excrement dilution water injection pipe at the S-bend depth. The water outlet of the turbine volute is communicated with the water inlet of the hollow frame by a hose, and the tap water inlet of the turbine is communicated with the water outlet of the valve body by a hose. The whole process of flushing the toilet bowl is as follows: the valve body is opened, tap water enters the volute through the hose by the tap water inlet of the water turbine to drive the impeller, then flows out from the water outlet of the volute, then enters the hollow frame through the hose by the water inlet of the hollow frame, then enters the bedpan through the fine water injection holes uniformly distributed along the periphery of the hollow frame, and finally washes the bedpan to be gathered into the S-bend inlet. The novel S-bend can ensure that the suction kinetic energy of the propeller is not completely dependent on the atmospheric pressure, so that the suction process is uninterrupted, the front excrement liquid is continuously pumped away, the rear clear water continuously follows the sequential flow, the mixing of the clear water and the excrement is avoided to the greatest extent, and the water consumption for flushing the toilet once is minimized. The excrement dilution water injection pipe directly leads a part of clear water to the stirring knife, so that the excrement is fully crushed and diluted before reaching the screw propeller, and can be smoothly pumped away by the screw propeller like urine. The upper port of the ampulla bearing body is provided with a member capable of installing or detaching the water turbine, so that the member becomes an openable position of the S-bend, is convenient to open at any time, and is convenient to replace damaged parts and clean scale at the S-bend.
