The perforated plate at one end is used to connect the power mechanism; the first opening is formed at the top of the side wall of the exhaust pipe 8, which is used to connect the inside of the exhaust pipe 8 with the outside, and the waste liquid flows into the exhaust pipe 8 through the first opening and flows out through the other end of the exhaust pipe 8.

[0030] The exhaust rotating shaft 11 is located in the exhaust pipe 8 and is used to push the waste liquid in the exhaust pipe 8 to flow; the second opening is uniformly formed on the outer wall of the exhaust rotating shaft 11 along the axis direction of the stirring blade, and the liquid inlet channel is formed in the inside of the exhaust rotating shaft 11. The second opening and the liquid inlet channel are communicated, so that the liquid inlet channel is communicated with the inside of the exhaust pipe 8 through the second opening, and the fluid in the liquid inlet channel flows into the exhaust pipe 8 through the second opening, which is used to clean the inner wall of the exhaust pipe 8 or prevent the waste liquid from flowing back into the exhaust rotating shaft 11.

[0031] The motor 3 includes a driving shaft, and a specific model of the motor 3 is RS-550VC-7525. The motor 3 is connected with the power supply and is used to provide power for the motor 3; the driving shaft is provided with the driving wheel 10, which is used to rotate synchronously with the driving shaft; the synchronous belt 13 is engaged and connected on the driving wheel 10 and the driven wheel 12, which is used to synchronously drive the driving wheel 10 and the driven wheel 12; the driven wheel 12 is arranged on one side of the driving wheel 10 and is driven by the synchronous belt 13 to rotate, which is used to drive the exhaust rotating shaft 11 arranged on the axis of the driven wheel 12 to rotate; the exhaust rotating shaft 11 is used to push the waste liquid in the exhaust pipe 8 to flow to the other end of the exhaust pipe 8.

[0033] The anti-backflow cleaning mechanism includes a fluid communication valve, which is used to switch and control the type of fluid. A hose is arranged on one side of the fluid communication valve, and the other end of the hose is connected with the liquid inlet channel. The hose is used to connect the fluid communication valve with the liquid inlet channel, so that the fluid in the fluid communication valve flows into the liquid inlet channel through the hose.

[0034] As an embodiment of the present application, as shown in Figure 1 and Figure 5 The outer wall of the waste discharge rotating shaft 11 is provided with stirring blades along its length direction, which are spirally wound and fixed on the waste discharge rotating shaft 11. The spiral stirring blades are used to move the waste liquid in the spiral direction. The edges of the stirring blades abut against the inner wall of the waste discharge pipe 8 to scrape the inner wall of the waste discharge pipe 8 while pushing the waste liquid to flow, so as to avoid the waste liquid adhering to the inner wall of the waste discharge pipe 8, thereby ensuring the smooth discharge of the liquid and reducing the risk of pipe blockage.

[0035] As an embodiment of the present application, as shown in Figure 2 and Figure 3 The motor housing 1 is provided outside the power mechanism, and a driving cavity is arranged inside the motor housing 1 to fix the power mechanism, so as to avoid damage of the power mechanism caused by collision. The motor housing 1 is made of corrosion-resistant stainless steel material, so as to avoid the chemical waste liquid with corrosion effect splashing on the driving wheel 10, the driven wheel 12 and the synchronous belt 13, thereby avoiding corrosion and damage of the power mechanism and affecting the waste liquid discharge efficiency.

[0036] Specifically, the driving wheel 10 is rotatably arranged on one side between the inner walls at both ends of the driving cavity, the driven wheel 12 is rotatably arranged on the other side between the inner walls at both ends of the driving cavity, and the synchronous belt 13 meshingly connected with the driving wheel 10 and the driven wheel 12 is arranged in the driving cavity. By rotatably arranging the driving wheel 10 and the driven wheel 12 and the synchronous belt in the driving cavity, the connection structure is stable, so as to avoid the synchronous belt 13 falling off or the gear of the driving wheel 10 and the driven wheel 12 being damaged due to collision, thereby affecting the discharge efficiency.

[0037] As an embodiment of the present application, as shown in Figure 2 and Figure 3 The motor housing 1 comprises a mounting plate 2, which is a square plate structure. A flange structure is arranged on one side of the mounting plate 2 around the perforated plate arranged at one port of the waste discharge pipe 8, so as to be connected and fixed with the perforated plate arranged at one port of the waste discharge pipe 8 through the flange structure.

[0038] A first through hole is arranged in the middle of the mounting plate 2, a second opening is arranged in the side wall of the motor housing 1 connected with the first through hole, the diameter of the first through hole is the same as that of the second opening and the diameter of the perforated plate, and one end of the waste discharge rotating shaft 11 is connected with the shaft center of the driven wheel 12 through the perforated plate, the first through hole and the second opening, so as to continuously provide power to make the waste discharge rotating shaft 11 continuously rotate.

[0039] The motor 3 is fixedly arranged on the outer wall surface of the motor shield 1, and is arranged on the side of the motor shield 1 for connecting the same side wall of the waste pipe 8 and is located on the same side wall surface of the driving wheel 10, wherein a first opening is provided through the position of the side wall of the motor shield 1 corresponding to the motor 3, and the driving shaft of the motor 3 is connected with the driving wheel 10 through the first opening. By adopting this connection mode, the motor 3 is in close contact with the motor shield 1, and the driving shaft is located in the connection between the motor shield 1 and the motor, which can prevent the waste liquid from splashing on the exposed driving shaft, so as to prevent the driving shaft of the motor 3 from being damaged and affect the driving efficiency of the motor 3.

[0040] As an embodiment of the present application, as shown in Figure 2 The clamping part further comprises an upper clamping plate 6, a lower clamping plate 5, an upper fixing plate 14 and a lower support fixing plate 7.

[0041] Specifically, the upper clamping plate 6 and the lower clamping plate 5 are arranged in parallel at the upper and lower ends of the opening of the waste pipe 8, and the upper clamping plate 6 and the lower clamping plate 5 are fixed by bolts. The opening is positioned and clamped by the upper clamping plate 6 and the lower clamping plate 5.

[0042] The top end of the upper clamping plate 6 is fixedly connected with the bottom end of the upper fixing plate 14, and the liquid inlet 4 is arranged at the top end of the upper fixing plate 14. The upper fixing plate 14 is a square fixed block. Since the liquid inlet 4 is a through hole and the hole diameter is larger than the opening diameter, the equipment requiring liquid discharge can be inserted into the liquid inlet 4, so that the upper fixing plate 14 can assist in fixing and supporting the equipment.

[0043] The top end of the lower support fixing plate 7 is arranged at the bottom end of the lower clamping plate 5 for supporting and fixing the lower clamping plate 5. The lower support fixing plate 7 is a square connecting plate structure, which can be connected with other lower support fixing plates 7 to change the support height, so as to change the flow direction of the waste liquid in the waste pipe 8 by physical means.

[0044] As an embodiment of the present application, as shown in Figure 1 and Figure 2 One or more openings are arranged at the upper end of the waste pipe 8 along the flow direction of the waste liquid in the waste pipe 8. By arranging multiple openings, the utilization rate of the waste pipe 8 can be improved, and a clamping part is arranged at the corresponding opening for positioning the opening and assisting in fixing and supporting multiple liquid discharge equipment.

[0045] Specifically, two openings can be formed on the waste pipe 8, and then a clamping component is arranged at each of the two openings to improve the utilization of the waste pipe 8. The clamping component near the power mechanism is the first clamping component, and two lower support fixed plates 7 are arranged at the bottom end of the lower clamping plate 5. The other clamping component is the second clamping component, and one lower support fixed plate 7 is arranged at the bottom end of the lower clamping plate 5. The vertical position of the opening of the first clamping component is higher than that of the second clamping component, so that the waste liquid in the waste pipe 8 has a tendency to flow from the position of the opening of the first clamping component to the position of the opening of the second clamping component, avoiding the waste liquid from flowing back due to too many openings.

[0046] As shown in an embodiment of the present application, Figure 1 The waste assembly comprises a connecting seat 9, an elbow, a first through hole, a positioning plate, and a corrugated pipe.

[0047] A first through hole is formed below the outlet end of the waste pipe 8, and the waste liquid flows out through the first through hole after flowing to the outlet end of the waste pipe 8. Positioning plates are arranged on the side walls of the waste pipe 8 on both sides of the first through hole. The elbow is arranged in a group of the positioning plates, and the positioning plates are used to stabilize the elbow. A connecting seat 9 is arranged on one of the positioning plates, and the other end of the elbow communicates with the positioning plate provided with the connecting seat 9. The elbow is used to communicate the first through hole with the connecting seat 9, so that the waste liquid flows out through the connecting seat 9 finally. The corrugated pipe is installed on the connecting seat 9, and the corrugated pipe is used to connect additional liquid discharge pipes, which can be used to discharge the waste liquid into the remaining liquid discharge pipes.

[0048] Specifically, the outer wall of the corrugated pipe has a plurality of continuous corrugated structures, and is used to connect additional liquid discharge pipes. The inner wall of the connecting end of the corrugated pipe can adopt an inverted hook-shaped concave-convex structure. When the liquid discharge pipe is connected with the corrugated pipe, only plug-in connection is needed. The inverted hook-shaped concave-convex structure of the inner wall of the liquid discharge pipe is clamped with the corrugated structure of the outer wall of the corrugated pipe, and the connection has stability.

[0049] As shown in an embodiment of the present application, Figure 1 The anti-backflow cleaning mechanism further comprises a rotary joint 15 and a connecting plate.

[0050] The connecting plate is connected with the perforated plate at the outlet end of the waste pipe 8 in the flow direction. The rotary joint 15 is arranged on the connecting plate. One end of the rotary joint 15 is connected with the waste discharge rotating shaft 11, and the other end is connected with the hose. The rotary joint 15 makes the hose communicate with the waste discharge rotating shaft 11.

[0051] As shown in an embodiment of the present application,Figure 1 As shown in the figure, the connecting plate is provided with a sealing end cover 17 for sealing the connection between the rotary joint 15 and the hose, avoiding the hose from falling off due to bumping. The sealing end cover 17 is provided with a through plate joint 16 at the other end, and the hose is connected with the rotary joint 15 through the through plate joint 16. The through plate joint 16 is used to support the hose, making the connection more secure.

[0052] As an embodiment of the present application, as shown in the figure, Figure 1 and Figure 4 As shown in the figure, the fluid communication valve comprises a valve body 18, a gland 19, a gas source inlet 20, a diaphragm 21, a second pipeline 22, a first pipeline 23, a third pipeline 25, a fourth pipeline 26, a groove, a switching pipeline 24, a handle, and an L-shaped flow channel.

[0053] The gland 19 is pressed on the valve body 18, and the gland 19 is provided with the gas source inlet 20 for communication with the gas source. The gas source is a device capable of realizing bidirectional gas flow and controlling the size of the gas flow, such as a pressure reducing valve. The valve body 18 is provided with the first pipeline 23 and the second pipeline 22 on both sides. The first pipeline 23 is used for fluid to enter the valve body 18; the second pipeline 22 is in communication with the hose and is used for fluid to flow out of the valve body 18 and enter the liquid inlet channel through the hose.

[0054] The first pipeline 23 is provided with a wide-mouth structure at one end outside the valve body 18, and the diameter of the channel becomes smaller as it extends to the inside of the valve body 18, until it is consistent with the internal pipeline of the valve body 18. Such a structure can increase the flow rate of fluid entering the internal pipeline of the valve body 18, thereby increasing the pressure when the fluid impacts the diaphragm 21. The second pipeline 22 is provided with a wide-mouth structure at one end outside the valve body 18, and the diameter of the channel becomes smaller as it extends to the inside of the valve body 18, until it is consistent with the internal pipeline of the valve body 18. Such a structure can reduce the flow rate of fluid flowing out of the valve body 18.

[0055] Specifically, a groove is opened between the gland 19 and the valve body 18; the groove is in communication with the gas source inlet 20, the first pipeline 23 and the second pipeline 22. The groove can be smooth arched, rectangular, circular, etc.

[0056] The diaphragm 21 can move to the side of the gas source inlet 20 with the fluid pressure and / or gas suction, so as to fit the gas source inlet 20, and make the first pipe 23 and the second pipe 22 communicate with each other. At this time, the diaphragm 21 is on the side of the gas source inlet 20, the groove forms a passage with the first pipe 23 and the second pipe 22, so that the fluid can flow from the first pipe 23 into the valve body 18, and then flow out from the second pipe 22; the diaphragm 21 can move to the side of the first pipe 23 and the second pipe 22 with the gas pressure, so as to fit the valve body 4 on the side of the first pipe 23 and the second pipe 22. At this time, the diaphragm 3 is on the side of the first pipe 23 and the second pipe 22, and the valve body inner pipe port corresponding to the first pipe 23 and the valve body inner pipe port corresponding to the second pipe 22 are simultaneously fitted by the diaphragm 3, so that the first pipe 23 and the second pipe 22 do not communicate with each other.

[0057] The switching pipe 24 is arranged on the first pipe 23, and is used to switch the third pipe 25 or the fourth pipe 26 to communicate with the first pipe 23. The third pipe 25 penetrates the side wall of the valve body 18, and is used to introduce gas. The fourth pipe 26 penetrates the side wall of the valve body 18, and is used to introduce liquid. The third pipe 25 and the fourth pipe 26 have the same hole diameter, and the hole diameter of the switching pipe 24 is the same as that of the third pipe 25 and the fourth pipe 26. The upper end of the switching pipe 24 penetrates the upper wall of the valve body 18, and a handle is arranged at the upper end of the switching pipe 24, which is used to hold and rotate the switching pipe 24.

[0058] Specifically, an L-shaped pipe can be arranged in the switching pipe 24. The L-shaped pipe has the same hole diameter as the third pipe 25, the fourth pipe 26 and the first pipe, and can tightly abut against the third pipe 25, the fourth pipe 26 and the first pipe after rotation, so as to avoid fluid leakage. The switching pipe 24 is arranged in a cavity in the valve body 18, and the cavity can accommodate the switching pipe 24 to rotate in the cavity, so as to realize pipe switching. Specifically, the two pipes of the L-shaped pipe have the same length.

[0059] In the above embodiment, the fluid communication valve controls the on-off of the fluid into the liquid inlet channel 8. The on-off control is realized by the diaphragm 21, the gas source inlet 20, the first pipeline 23 and the second pipeline 22. When the gas source pressure of the gas source inlet 20 is greater than the fluid pressure of the first pipeline 23, the diaphragm 21 adheres to the pipeline ports of the first pipeline 23 and the second pipeline 22, so that there is no communication relationship between the first pipeline 23 and the second pipeline 22. At this time, the fluid communication valve is in the closed state. When the gas source pressure of the gas source inlet 20 is less than the fluid pressure of the first pipeline 23, the diaphragm 21 moves to the side of the gas source inlet 20 and adheres to the gas source inlet 20, so that a communication path is formed between the first pipeline 23 and the second pipeline 22. At this time, the fluid communication valve is in the open state, and the fluid can enter the liquid inlet channel through the hose after passing through the fluid communication valve.

[0060] In the above embodiment, the fluid communication valve also realizes the switching control of the fluid into the liquid inlet channel. The switching control of the fluid into the liquid inlet channel is realized by the switching pipeline 24 and the first pipeline 23, the third pipeline 25 and the fourth pipeline 26. The switching pipeline 24 is set as a rotatable adjustable L-shaped flow channel. By rotating the switching pipeline 24, the communication relationship of the pipeline can be switched. That is, when the two pipeline ports of the switching pipeline 24 are respectively connected to the fourth pipeline 26 and the first pipeline 23, a communication path is formed between the fourth pipeline 26 and the first pipeline 23, so that the cleaning liquid in the fourth pipeline 26 can enter the first pipeline 23. When the two pipeline ports of the switching pipeline 24 are respectively connected to the third pipeline 25 and the first pipeline 23, a communication path is formed between the third pipeline 25 and the first pipeline 23, so that the gas in the third pipeline 25 can enter the first pipeline 23.

The motor 3 is started to drive the shaft to rotate, drive the driving wheel 10 fixedly installed thereon to rotate, and drive the driven wheel 12 through the synchronous belt 13 to rotate, and then the waste rotating shaft 11 arranged on the axis of the driven wheel 12 rotates. The outer wall of the waste rotating shaft 11 is provided with spiral stirring blades along the length direction, and the edges of the stirring blades abut against the inner wall of the waste pipe 8, so that the attachments on the inner wall of the waste pipe 8 are scraped off, and the waste liquid flows from the end of the outflow direction of the waste pipe 8, and flows out through the connecting seat 9. The corrugated pipe arranged on the connecting seat 9 is used to communicate with other liquid discharge pipes, so that the waste liquid can flow into other liquid discharge pipes.

[0064] The inner wall of the waste pipe 8 can be sprayed and cleaned by the control anti-backflow cleaning mechanism before or after use. Specifically, the cleaning liquid is communicated with the fourth pipeline 26, the position of the switching pipeline 24 is adjusted by holding the handle, the fourth pipeline 26 is communicated with the first pipeline 23, then the gas pressure in the gas source inlet 20 is reduced, the diaphragm 21 is attached to one side of the gas source inlet 20, the first pipeline 23 and the second pipeline 22 form a passage, the cleaning liquid flows from the fourth pipeline 26 into the first pipeline 23, and then flows into the second pipeline 22 through the groove, and then flows into the liquid inlet channel through the hose, and is sprayed outward through the second opening arranged on the waste rotating shaft 11, so as to clean the inner wall of the waste pipe 8. When the cleaning liquid is not needed to spray and clean the inner wall of the waste pipe 8, the gas is introduced into the third pipeline 25, the position of the switching pipeline 24 is adjusted by holding the handle, the third pipeline 25 is communicated with the first pipeline 23, then the gas pressure in the gas source inlet 20 is reduced, that is, the gas pressure on the side of the first pipeline 23 is greater than that on the side of the gas source inlet 20, the diaphragm 21 is attached to one side of the gas source inlet 20, the first pipeline 23 and the second pipeline 22 form a passage, the gas flows from the third pipeline 25 into the first pipeline 23, and then flows into the second pipeline 22 through the groove, and then flows into the liquid inlet channel through the hose, and is discharged outward through the second opening arranged on the waste rotating shaft 11, so that the waste liquid in the waste pipe 8 cannot enter the liquid inlet channel, and the effect of preventing backflow of the waste liquid is achieved.

[0065] During use, the anti-backflow cleaning mechanism increases the pressure inside the waste discharge pipe 8, making the waste liquid adhere more closely to the inner wall of the waste discharge pipe 8, making it easier for the waste discharge rotating shaft 11 to scrape it off. Specifically, compressed air is connected to the third pipe 25, and the position of the switching pipe 24 is adjusted by holding the handle, so that the third pipe 25 is connected to the first pipe 23. Then, the vacuum gas introduced into the air source inlet 20 is reduced, so that the compressed air flows from the third pipe 25 into the first pipe 23, flows through the groove into the second pipe 22, and then flows into the liquid inlet channel through the hose. The compressed air flows into the waste discharge pipe 8 through the second opening opened on the waste discharge rotating shaft 11, which is used to prevent the waste liquid from flowing into the liquid inlet channel through the second opening.
