Description

Technical Field

[0001] This utility model relates to the field of railway transportation technology, specifically to a pulverizing device for a high-speed train toilet. Background Technology

[0002] High-speed trains typically use vacuum toilets. Their working principle involves a turbine creating a vacuum within a pump, drawing waste from the toilet bowl into the pump, and then discharging it under pressure to a designated storage location. This method offers the advantages of both environmental protection and water conservation, consuming only one-twelfth the water of a typical household flush toilet per flush.

[0003] In previous designs of high-speed train toilets, the method of handling waste was relatively simple, usually relying solely on water flow to transport waste from the defecation area to the collection pipe. There was a lack of an effective mechanism specifically for pulverizing waste. This meant that large pieces of waste were prone to clogging. Once the pipe was blocked, not only would the normal operation of the toilet be interrupted, but also, in terms of odor control, traditional high-speed train toilets mostly relied on a simple water seal structure to block odors. However, this single odor control measure had limited effectiveness. On the one hand, the water seal was prone to failure due to water flow impact and evaporation; on the other hand, when waste accumulated in the collection tank, changes in air pressure could still allow odors to seep into the carriage through various gaps and channels, reducing the service quality of the high-speed train. Therefore, a waste pulverizing device for high-speed train toilets was needed to solve these problems. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The present invention relates to a pulverizing device for a train toilet, which uses a motor to drive a screw blade to rotate on the inner wall of a transmission pipe. At the same time, the transmission rod fixes the main rotating wheel, which is pulled by a belt to drive the crushing frame to crush the waste. This device can quickly crush the falling waste while transporting it to prevent blockage.

[0022] This utility model discloses a pulverizing device for a high-speed train toilet. A vacuum pump at the top of the main rotor draws air through an extraction pipe to reduce the air pressure inside the transmission pipe. Under the combined action of atmospheric pressure and water, the pulverized waste smoothly enters the pulverizing pipe. Water remains in the discharge pipe to form a water seal. Furthermore, as the waste falls and strikes a baffle, the baffle is elastically reset via a connecting block to block the outlet of the isolation pipe. This achieves double-layer protection and comprehensive odor control, ensuring a clean and comfortable environment around the high-speed train toilet. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4This utility model provides a pulverizing device for a train toilet, comprising a mounting plate 1 and a toilet bowl 6. The mounting plate 1 is an L-shaped support plate with a protruding elongated block at the top. A mounting bracket 2 is fixedly connected to the side wall of the mounting plate 1, and the mounting bracket 2 is fixed to the side of the mounting plate 1 by bolts.

[0032] A motor 3 is fixedly connected to the top of the mounting bracket 2. The motor 3 is the power source of the entire device. It is a DC motor 3 suitable for the operation environment of high-speed trains, which has the characteristics of high speed and high torque. A transmission rod 4 is fixedly connected to the drive end of the motor 3. A screw blade 5 is fixedly connected to the outside of the transmission rod 4. The transmission rod 4 bears the torque transmitted by the motor 3 and transmits it to the screw blade 5, so that the screw blade 5 rotates.

[0033] A discharge pipe 7 is fixedly connected to the top of the toilet bowl 6. The function of the discharge pipe 7 is to guide the waste in the toilet bowl 6 to flow there. A crushing pipe 8 is fixedly connected to the bottom of the discharge pipe 7. The crushing pipe 8 is the area for crushing waste. A crushing frame 9 is rotatably connected to the middle of the crushing pipe 8. The outer blades of the crushing frame 9 are staggered and connected to the outside of the rotating shaft to achieve the effect of crushing waste from multiple angles.

[0034] refer to Figure 2 A driven wheel 10 is fixedly connected to the side of the crusher frame 9 near the motor 3. A main wheel 12 is fixedly connected to the external end of the transmission rod 4 near the motor 3. A belt 11 is fitted around the driven wheel 10 and the main wheel 12. The driven wheel 10 is connected to the main wheel 12 via the belt 11, thereby realizing the power transmission between the crusher frame 9 and the transmission rod 4. The external rotating part of the screw blade 5 is connected to the inner wall of the transmission pipe 13. The screw blade 5 contacts the inner wall of the transmission pipe 13 to carry out the transmission work and prevent the crushed dirt from clogging.

[0035] refer to Figure 3 A vacuum pump 14 is installed at the top of the transmission pipe 13. The vacuum pump 14 is a device specifically designed for extracting gas and reducing the air pressure inside a container. A small, high-efficiency vacuum pump 14 suitable for the confined space and special operating environment of a high-speed train is selected. An extraction pipe 15 is installed on the side of the vacuum pump 14 closest to the motor 3. The bottom end of the extraction pipe 15 is fixedly connected to the middle of the top of the transmission pipe 13. The extraction pipe 15 is made of high-pressure resistant and corrosion-resistant pipe material, and its bottom end is fixedly connected to the middle of the top of the main rotor 12. Through the extraction pipe 15, the vacuum pump 14 can extract air from the main rotor 12, reducing the air pressure inside the main rotor 12. Under the combined action of atmospheric pressure and water, it helps the crushed waste to smoothly enter the crushing pipe 8, while also improving the overall working efficiency of the device.

[0036] A connecting hose 16 is provided on the right side of the toilet bowl 6. The connecting hose 16 is made of soft and corrosion-resistant rubber or plastic material, with good flexibility and sealing performance. One end of it is connected to the right side of the toilet bowl 6, and the other end is connected to the flushing component. When the toilet bowl 6 needs to be flushed, the water flows through the connecting hose 16 into the toilet bowl 6 and is flushed towards the discharge pipe 7 of the toilet bowl 6.

[0037] refer to Figure 4 , Figure 5 The feed pipe 7 has an internal isolation component to block odors. The isolation component includes an isolation pipe 17, which is made of corrosion-resistant plastic. A point block 18 is fixedly connected to the bottom end of the isolation pipe 17. A connecting block 19, which is U-shaped, is fixedly connected to the side wall of the point block 18. A rotating roller 20 is rotatably connected to the middle of the connecting block 19. A torsion spring 21 is sleeved on the outside of the rotating roller 20. The torsion spring 21 is a spring that can store and release elastic potential energy. When subjected to external force, the torsion spring 21 deforms and stores energy. When the external force disappears, the torsion spring 21 returns to its original shape and releases energy.

[0038] Connecting blocks 22 are rotatably connected to the two outer ends of the torsion spring 21. The side of connecting block 22 near the rotating roller 20 is rotatably connected to the side of connecting block 19 near the rotating roller 20. Connecting block 22 is rotatably connected to the torsion spring 21 and connecting block 19 through a pin component, ensuring that connecting block 22 can move flexibly under the action of the torsion spring 21.

[0039] A baffle 23 is fixedly connected to the side of connecting block 22 away from the rotating roller 20. The side of baffle 23 closest to the rotating roller 20 is rotatably connected to the outside of the point block 18. The top of baffle 23 engages with the bottom of the isolation tube 17. Baffle 23 is made of corrosion-resistant plastic or metal and its function is to normally block the outlet of isolation tube 17 to prevent odors from escaping from the discharge pipe 7. When dirt passes through the discharge pipe 7, the dirt will hit baffle 23, causing baffle 23 to rotate around the rotating roller 20, opening the outlet of isolation tube 17 and allowing the dirt to pass through. After the dirt passes through, baffle 23 will reset under the elastic force of torsion spring 21, re-blocking the outlet of isolation tube 17.

[0040] A sludge storage tank 24 is detachably connected to the top of the mounting plate 1. The sludge storage tank 24 stores crushed and filtered sludge and is made of corrosion-resistant, high-strength plastic or metal. A screen plate 25 is detachably connected to the top of the sludge storage tank 24. The screen plate 25 has many small screen holes, which filter the crushed sludge falling from the bend in the transmission pipe 13. Larger impurities and incompletely crushed sludge remain on the screen plate 25, while only fully crushed fine sludge can pass through the screen holes into the sludge storage tank 24, thus preventing clogging. A clamp 26 is detachably connected to the outside of the top of the sludge storage tank 24. The clamp 26 is detachably connected to the side of the transmission pipe 13 near the screen plate 25. The clamp 26 is made of metal and has good fastening performance. By clamping the transmission pipe 13 and the inlet of the sludge storage tank 24, the clamp 26 effectively ensures that the sludge storage tank 24 remains stable during operation and does not shake or shift.

[0041] Working principle: In use, the motor 3 is started first, and the motor 3 drives the screw blade 5 to rotate and slide on the inner wall of the transmission pipe 13 through the transmission rod 4. In addition, the external main rotating wheel 12 of the transmission rod 4 will be pulled by the belt 11 to drive the crushing frame 9 to rotate synchronously in the crushing pipe 8. Then, the external flushing component flows into the connecting hose 16 to the discharge pipe 7 of the toilet 6 to flush water. The rapid water flow flows into the crushing pipe 8 through the discharge pipe 7 and the isolation pipe 17 inside the discharge pipe 7. After the sewage enters the crushing pipe 8, it is crushed by the high-speed rotating crushing frame 9. The crushed sewage flows into the transmission pipe 13 through the bottom pipe of the crushing pipe 8. It is driven by the continuously rotating screw blade 5 to move to the bend of the transmission pipe 13 and fall down. It is then filtered by the screen plate 25 and flows into the sewage storage tank 24. This effectively crushes the sewage while preventing the crushed sewage from clogging.

[0042] As the waste passes through the discharge pipe 7 and the point block 18, a vacuum pump 14 located at the top of the transmission pipe 13 will pump air from the transmission pipe 13 through the extraction pipe 15 to reduce the air pressure inside the transmission pipe 13. Under the combined action of atmospheric pressure and water, the crushed waste can smoothly enter the crushing pipe 8, while some water will remain in the discharge pipe 7, achieving a water seal effect. In addition, the waste will hit the baffle 23 when it falls, and the baffle 23 is fixedly connected to one end of the torsion spring 21 through the connecting block 22. Therefore, when the baffle 23 is hit, it will reset under the elastic force of the torsion spring 21 and re-block the outlet of the isolation pipe 17, thereby achieving double protection to prevent the emission of odors.
