Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum sewage discharge, in particular to a filtering device for a vacuum sewage discharge main machine. Background Art
[0002] In the railway vacuum sewage discharge system, a rotor pump vacuum negative pressure structure is generally used for sewage suction or discharge at present. In the actual application process, sewage directly converges through the pipeline and passes through the vacuum sewage discharge main machine. However, due to the complex sewage discharge environment, the sewage often contains sharp or soft solid impurities such as cotton fabrics, metal screws, and coins that are difficult to pass through the vacuum rotor pump. The existence of these solid impurities brings many problems to the sewage discharge system. On the one hand, the solid impurities are likely to cause pipeline blockage, affecting the normal operation of the sewage discharge system. Once blockage occurs, not only a large amount of time and manpower are required for cleaning, but also the sewage discharge work is interrupted, affecting the normal operation order of railway stations. On the other hand, the solid impurities may wind around the components of the rotor pump, resulting in poor operation of the rotor pump, increasing the energy consumption of the equipment. At the same time, the sharp solid impurities will also cause abnormal wear to the rotor pump, reducing the service life of the vacuum sewage discharge main machine and increasing the maintenance cost of the equipment.

[0024] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification.
[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0026] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate from or mutually exclusive of other embodiments selectively.
[0027] Embodiment 1
[0028] Referring to Figures 1 - 5 , which is the first embodiment of the present utility model. This embodiment provides a vacuum sewage discharge main machine filtering device. The vacuum sewage discharge main machine filtering device includes a main body assembly 100, which includes a vacuum sewage discharge machine interception box 101, a fixing plate 102, and an interception net 103. The fixing plate 102 is fixed inside the vacuum sewage discharge machine interception box 101, and the interception net 103 is arranged on the fixing plate 102.
[0029] The vacuum sewage discharge machine interception box 101 is used to intercept impurities such as cotton fabrics, metal screws, and coins in the sewage of the train toilet collection box, preventing the sewage from entering the vacuum sewage discharge machine and causing blockage, entanglement, and abnormal wear, thereby affecting the service life of the main machine. The interception net 103 can effectively block solid impurities such as cotton fabrics, metal screws, and coins that are mixed during operation and are sharp or soft and difficult to pass through the vacuum rotor pump, and can effectively intercept metal screws and other solids with a diameter of more than 8 mm, while not affecting the pressure in the pipeline and the fluidity of the liquid during the operation of the equipment. The fixing plate 102 supports the interception net 103 to prevent the interception net 103 from moving in the vacuum sewage discharge machine interception box 101.
[0030] A cleaning component 200 is located inside the vacuum sewage discharge machine interception box 101 and includes an energy supply component 201, which is arranged on one side of the interception net 103 and includes a worm 201a, a protective cover 201b, a water injection conduit 201c, and a diversion conduit 201d. A through hole 103-1 is opened in the interception net 103, and the worm 201a is inserted into the through hole 103-1. One end of the protective cover 201b is fixed on the interception net 103. A water injection hole 101-1 is opened in the vacuum sewage discharge machine interception box 101, and the water injection conduit 201c is inserted into the water injection hole 101-1. The diversion conduit 201d is fixed below the water injection conduit 201c.
[0031] The energy supply component 201 provides energy for the subsequent cleaning interception net 103. The worm 201a has a long cylindrical rod-like structure. When water flows through the worm 201a, it will form a specific angle and contact mode with the spiral surface of the worm 201a. The water flows along the spiral direction of the worm 201a. During this process, the impact force of the water continuously acts on the spiral surface of the worm 201a, thereby generating a tangential force. This tangential force causes the worm 201a to start rotating under the continuous action of the water flow. The protective cover 201b can prevent dirt from contacting the worm 201a, thereby preventing the dirt from hindering the rotation of the worm 201a and further affecting the energy supply.
[0032] Through the setting of the water injection conduit 201c, it is convenient for water to enter the interior of the vacuum sewage discharge machine interception box 101, and then clean the interior of the vacuum sewage discharge machine interception box 101. The diversion pipe 201d is used to ensure that a part of the injected running water will enter the protective cover 201b, thereby flowing through the spiral surface of the worm 201a, and then causing the worm 201a to rotate. This is the prior art, and this solution will not be elaborated much, and those skilled in the art can clearly understand the working principle.
[0033] After the vacuum sewage discharge machine interception box 101 intercepts the dirt from the train toilet collection box and completes the discharge operation, running water is injected into the interior of the vacuum sewage discharge machine interception box 101 through the water injection conduit 201c to clean the interior of the vacuum sewage discharge machine interception box 101. A part of the running water will flow into the diversion pipe 201d, and the water flow in the diversion pipe 201d flows into the protective cover 201b, thereby flowing through the spiral surface of the worm 201a, and then causing the worm 201a to rotate.
[0034] Embodiment 2
[0035] Refer to Figures 1 - 5 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.
[0036] Specifically, the cleaning assembly 200 further includes a cleaning member 202, which is arranged on one side of the energy supply member 201 and includes a brush plate 202a and a brush head 202b. The brush plate 202a is fixed to the bottom of the worm 201a, and the brush head 202b is fixed to one side of the brush plate 202a.
[0037] The cleaning member 202 is used to clean the interception net 103. The brush plate 202a is arranged at the bottom of the interception net 103. One end of the brush head 202b is fixed to the brush plate 202a, and the other end is in contact with the interception net 103. When the water flow impacts the spiral surface of the worm 201a and drives the worm 201a to rotate, the worm 201a will drive the brush plate 202a to rotate, and then drive the brush head 202b to rotate, thereby cleaning the bottom of the interception net 103 and preventing the interception net 103 from being blocked during long-term use.
[0038] Specifically, a support block 201e is fixed inside the protective cover 201b, and the support block 201e is connected to the worm 201a by bearings.
[0039] There are two support blocks 201e. The worm 201a is supported by the support blocks 201e and positioned at the same time to prevent the position of the worm 201a from moving during rotation, thereby affecting the cleaning work of the interception net 103.
[0040] Specifically, a one-way diaphragm valve 201f is fixed to the inner wall of the through hole 103-1. The one-way diaphragm valve 201f is funnel-shaped, and the smaller diameter end of the one-way diaphragm valve 201f contacts the worm 201a.
[0041] The one-way diaphragm valve 201f is used to prevent dirt from entering the protective cover 201b from the bottom of the worm 201a, which affects the rotation of the worm 201a. When the fluid flows downward from above the protective cover 201b, the pressure of the fluid will act on the diaphragm, causing it to bend in a specific direction, thereby opening the valve passage and allowing the fluid to pass through smoothly. When the fluid attempts to flow in the reverse direction, the diaphragm will closely adhere to the valve seat under the action of the reverse pressure, forming a reliable seal to prevent the reverse flow of the fluid. This is the prior art, and this solution will not be elaborated much, and those skilled in the art can clearly understand the working principle.
[0042] Specifically, the through hole 103-1 is located at the center of the interception net 103, and the water injection hole 101-1 is coaxial with the through hole 103-1.
[0043] The coaxial setting ensures that when the water flows from the water injection conduit 201c into the interception box 101 of the vacuum sewage discharge machine, a part of the water will always flow through the diversion pipe 201d, thereby driving the worm 201a to rotate, and thus completing the cleaning of the interception net 103.
[0044] Specifically, the water injection conduit 201c is provided with a through groove 201c-1.
[0045] There are multiple through grooves 201c-1, which are used to allow the water that has not entered the diversion pipe 201d to continue to flow around, so as to facilitate the cleaning of other positions inside the interception box 101 of the vacuum sewage discharge machine.
[0046] Embodiment 3
[0047] Refer to Figures 1 - 5 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.
[0048] Specifically, the diameter of the diversion pipe 201d is smaller than the diameter of the top of the protective cover 201b.
[0049] By designing the diameter of the diversion pipe 201d, the water flow can have a greater impact force, making it easier to drive the rotation of the worm 201a, and at the same time, it will not prevent the cleaning of other positions inside the interception box 101 of the vacuum sewage discharge machine.
[0050] Specifically, the interception net 103 is connected to the fixed plate 102 by bolts.
[0051] The fixed plate 102 provides stable and reliable support for the interception net 103. The bolt connection is convenient for installation and disassembly, and at the same time ensures that the fixed plate 102 and the interception net 103 are firmly and reliably connected.
[0052] Specifically, the main body assembly 100 further includes a sewage inlet 104, a sewage outlet 105, and an interception object discharge port 106. The sewage inlet 104 is arranged on one side of the interception box 101 of the vacuum sewage discharge machine, the sewage outlet 105 is located on the other side of the interception box 101 of the vacuum sewage discharge machine, and the interception object discharge port 106 is arranged at the bottom of the interception box 101 of the vacuum sewage discharge machine.
[0053] The height of the sewage outlet 105 is lower than the height of the protective cover 201b, so as to ensure that the sewage in the train toilet box will not flow to the worm 201a through the top of the protective cover 201b.
[0054] The impurities in the sewage of the train toilet box form a vacuum environment through the negative pressure generated by the vacuum unit. First, they enter the interception box 101 of the vacuum sewage discharge machine through the sewage inlet 104, and are intercepted by the interception net 103. The separated liquid of the sewage enters the main vacuum sewage discharge machine through the sewage outlet 105 and is discharged to the septic tank. The intercepted impurities are collected in the tank below the interception net. After the sewage suction is completed, the sewage cleaning operation starts. The main machine is started, and the intercepted sundries are sucked into the transfer box from the interception object discharge port 106. The sundries in the transfer box are controlled by the gate valve switch and are normally discharged to the septic tank by the sewage discharge operation of the main machine, realizing the effect of intercepting and discharging sundries. This is the prior art, and this solution will not be elaborated much, and those skilled in the art can clearly understand the working principle.
[0055] Specifically, the interception box 101 of the vacuum sewage discharge machine is provided with an exhaust hole 101-2, and a pressure gauge 107 is fixed on the top of the interception box 101 of the vacuum sewage discharge machine.
[0056] The exhaust hole 101-2 can keep the inside of the interception box 101 of the vacuum sewage discharge machine in a certain communication with the outside atmosphere, so as to balance the air pressure inside and outside the box. The pressure gauge 107 can display the pressure situation inside the interception box 101 of the vacuum sewage discharge machine in real time. The operator can understand the pressure change inside the box at any time through the pressure gauge 107, and discover abnormal situations in time and take corresponding measures.
[0057] During use, the dirt and impurities in the train's centralized toilet waste box create a vacuum environment through the negative pressure generated by the vacuum unit. First, they enter the vacuum sewage discharge machine interception box 101 from the sewage inlet 104 and are intercepted by the interception net 103. The liquid separated from the dirt enters the vacuum sewage discharge main machine through the sewage outlet 105 and is discharged into the septic tank. The intercepted impurities are collected in the tank below the interception net. After the sewage suction is completed, the cleaning operation begins. The main machine is started, and the intercepted sundries are sucked into the transfer box from the interception object discharge port 106. The sundries in the transfer box are controlled by the gate valve switch and are discharged into the septic tank through the normal sewage discharge operation of the main machine, achieving the effect of intercepting and discharging sundries.
[0058] When the operation of intercepting and discharging sundries is completed, water is injected into the vacuum sewage discharge machine interception box 101 through the water injection conduit 201c. A part of the water flow will flow into the diversion pipe 201d, and the water flow in the diversion pipe 201d flows into the protective cover 201b. When the water flow passes through the worm 201a and impacts the spiral surface of the worm 201a, a tangential force for pushing and rotating will be generated, thereby driving the rotation of the worm 201a, and then driving the rotation of the brush plate 202a. The brush plate 202a drives the movement of the brush head 202b, so as to clean the solid impurities on the interception net 103. At the same time, the water flow that does not enter the diversion pipe 201d can continue to flow around, so as to facilitate the cleaning of other positions inside the vacuum sewage discharge machine interception box 101 for the next use.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
