Description

Technical Field

[0001] This application relates to the technical field of abrasive waste liquid conveying, and in particular to an abrasive waste liquid conveying device. Background Technology

[0002] Currently, with the continuous development of modern industry towards high precision, high efficiency, and green manufacturing, environmental protection and sustainable development have become core issues that the manufacturing industry cannot avoid. In modern machining processes such as metal cutting and precision grinding, a large amount of grinding fluid (also known as coolant) is usually required to effectively cool and lubricate the high-speed moving cutting tools or grinding wheels and workpieces, while also flushing away the chips generated during machining.

[0003] During machining, grinding fluid mixes with detached abrasive particles (such as silicon carbide and alumina) and metal shavings ground from the workpiece, forming a solid-liquid mixture containing a large number of solid particles, commonly known as abrasive waste liquid. Direct discharge of this abrasive waste liquid not only wastes valuable grinding fluid resources and increases production costs, but more importantly, the metal particles, abrasive microparticles, and various chemical additives it contains will cause serious pollution to soil and water bodies, placing enormous pressure on the ecological environment. Therefore, promoting "green manufacturing" and centrally treating abrasive waste liquid to purify and recycle grinding fluid has become an industry consensus and an important environmental protection measure. To save costs and protect the environment, the abrasive waste liquid needs to be extracted from the machine tool grinding chamber through pipelines and transported to a centralized filtration device for treatment, thus achieving the recycling of the grinding fluid. In this process, a pump is typically used as the power source for transportation.

[0004] However, during the process of using pumps to transport this abrasive waste liquid, since the density of abrasive and metal shavings is much greater than that of liquid, they are very easy to settle in the fluid. Therefore, when the pump stops working and the flow rate in the pipeline decreases, the suspended solid particles (abrasive and metal shavings) will settle rapidly and form a sediment layer in the transport pipeline, which can easily lead to overload or blockage when the pump is started again.

[0005] Therefore, there is an urgent need for an abrasive waste liquid conveying device to effectively reduce the deposition of solid particles. Summary of the Invention

[0006] To reduce the deposition of solid particles, this application provides an abrasive waste liquid conveying device.

[0007] This application provides an abrasive waste liquid conveying device, which adopts the following technical solution: An abrasive waste liquid conveying device, comprising: A conveying body, one end of which is provided with a discharge port; A buffer module is connected to the discharge port, and the conveying body can convey abrasive waste liquid through the buffer module so that the liquid in the abrasive waste liquid is stored in the buffer module; A backflushing module is installed on the buffer module and is connected to the discharge port. When the conveying body stops working, the backflushing module is used to transport the liquid stored in the buffer module into the conveying body.

[0008] By adopting the above technical solution, the conveying body can transport the abrasive waste liquid through the outlet to the buffer module, and then through the buffer module to the filtration device, so as to treat the abrasive waste liquid and realize the recycling of grinding fluid. Simultaneously, a portion of the liquid in the abrasive waste liquid is stored in the buffer module. When the conveying body stops working, solid particles such as abrasive and metal shavings, due to their higher density than liquid and reduced flow velocity, tend to settle within the conveying body. At this time, the backflushing module transports the liquid stored in the buffer module back into the conveying body. The flow energy of the liquid washes away the settled solid particles, thus helping to prevent the formation of a sediment layer within the conveying body. This reduces the risk of overload or blockage when the conveying body restarts, avoiding waste liquid leakage caused by overload or blockage. This helps save costs and protect the environment, and is beneficial for the subsequent transport of abrasive waste liquid and the stable operation of the entire conveying device, promoting the purification and recycling of grinding fluid during the abrasive waste liquid treatment process.

[0009] Optionally, the buffer component includes a buffer box and a filter component disposed within the buffer box. The buffer box has a first chamber and a second chamber. The filter component is disposed between the first chamber and the second chamber. The first chamber is connected to the discharge port. The backflushing module includes a backflushing component and a one-way component. The backflushing component is disposed within the second chamber. The one-way component is connected to both the second chamber and the discharge port.

[0010] By adopting the above technical solution, when the conveying body transports the abrasive waste liquid into the first chamber and then to the filtration device, a portion of the liquid in the abrasive waste liquid passes through the filtration assembly into the second chamber. The filtration assembly filters the liquid to reduce the amount of solid particles carried in it, thus facilitating subsequent backflushing operations. Furthermore, when the conveying body stops working, the backflushing assembly can push the liquid in the second chamber through the one-way component to the outlet and then back into the conveying body, preventing solid particles in the abrasive waste liquid from depositing in the conveying body. This reduces the risk of overload or blockage when the conveying body restarts, thereby helping to avoid waste liquid leakage, saving costs, and protecting the environment.

[0011] Optionally, the filtration assembly includes a baffle and a filter element. The baffle is disposed between the first chamber and the second chamber, and the filter element is disposed between the baffle and the top wall of the buffer tank. The filter element is used to filter the liquid entering the second chamber from the first chamber.

[0012] By adopting the above technical solution, when the abrasive waste liquid enters the second chamber from the first chamber, the filter element located between the baffle and the top wall of the buffer tank can play a blocking role, so that solid particles in the abrasive waste liquid cannot pass through the filter element smoothly, while the liquid can pass through the filter element. This achieves filtration of the liquid entering the second chamber from the first chamber, which can prevent solid particles from entering the second chamber and causing damage to subsequent equipment, and can also ensure that the liquid entering the second chamber is relatively pure. In addition, the baffle can store some liquid in the second chamber, which facilitates the normal operation of the subsequent backflushing module, reduces the probability of failure caused by excessive impurities, and improves the stability and service life of the entire abrasive waste liquid conveying device.

[0013] Optionally, the first chamber has a circular cross-section, the center line of the discharge port is arranged along the tangent direction of the circumference of the first chamber, and the discharge port is connected to the first chamber.

[0014] By adopting the above technical solution, the cross-section of the first chamber is circular, and the center line of the discharge port is arranged along the tangential direction of the circumference of the first chamber. When the abrasive waste liquid enters the first chamber from the discharge port, due to the tangential and interconnected structure, the abrasive waste liquid will flow along the tangential direction of the circumference of the first chamber, so that the abrasive waste liquid forms a rotating flow in the circular first chamber. This rotating flow can prevent solid particles in the abrasive waste liquid from being deposited at the bottom of the first chamber, but instead allow them to move continuously with the rotating liquid. This avoids the normal function of the buffer module and the subsequent conveying process being affected by the sedimentation and accumulation of solid particles, thereby improving the overall stability and reliability of the abrasive waste liquid conveying device.

[0015] Optionally, the recoil assembly includes a sliding drive and an extrusion member. The sliding drive is disposed on the buffer box, and the extrusion member is slidably disposed in the second chamber and fits against the inner wall of the second chamber. The sliding drive is connected to the extrusion member, and the sliding drive is used to drive the extrusion member to move in the second chamber.

[0016] By adopting the above technical solution, when the conveying body stops working, the sliding drive can drive the extrusion member to move in the second chamber, so as to cause the liquid stored in the second chamber to flow to the one-way component connected to the second chamber, thereby facilitating the delivery of liquid to the conveying body. The flow of liquid can be used to flush the conveying body, prevent solid particles from depositing, and thus help reduce the occurrence of overload or blockage when the conveying body is started again, ensuring the normal operation and service life of the abrasive waste liquid conveying device.

[0017] Optionally, the extrusion component includes a push plate and a float plate. The push plate and the float plate are slidably disposed in the second chamber and are attached to the inner wall of the second chamber. The push plate is connected to the sliding drive component. The float plate can float on the liquid. A clearance groove is provided on the float plate. When the push plate contacts the float plate, the push plate can block the clearance groove. A collection groove is provided on the float plate. A magnetic suction component is provided in the collection groove.

[0018] By adopting the above technical solution, the pusher plate and float plate can slide against the inner wall of the second chamber. When the conveying body is working normally, the float plate can float on the liquid and has a clearance groove on it, allowing the liquid to flow through the clearance groove and facilitating liquid storage in the second chamber. When the conveying body stops working, solid particles such as abrasive and metal shavings tend to settle in the conveying body. At this time, the sliding drive component drives the pusher plate to move, gradually approaching the float plate until it contacts the float plate and blocks the clearance groove. Then the pusher plate continues to move, pushing the liquid through the one-way component to the outlet and then back into the conveying body. The flow of the liquid has a flushing effect on the settled solid particles, preventing solid particles from depositing in the conveying body and reducing the risk of overload or blockage when the conveying body starts up again. At the same time, the magnetic adsorption component in the collection tank on the float plate can adsorb magnetic particles in the abrasive waste liquid, separating the magnetic particles from the abrasive waste liquid and collecting them in the collection tank. This helps reduce the content of magnetic particles in the abrasive waste liquid, further reducing the risk of blockage caused by magnetic particle deposition, ensuring stable operation of the device and facilitating the subsequent treatment of the abrasive waste liquid.

[0019] Optionally, the discharge port has a circular cross-section, and the one-way component includes a drain pipe and a one-way valve disposed on the drain pipe. One end of the drain pipe is connected to the second chamber, and the other end of the drain pipe is tangent to and connected to the discharge port.

[0020] By adopting the above technical solution, the discharge port has a circular cross-section, and the drain pipe is tangential to and connected to the discharge port, allowing the liquid flowing from the drain pipe to enter the discharge port along the tangential direction of the discharge port's circumference, forming a swirling flow. A one-way valve ensures that the liquid can only flow from the second chamber to the discharge port, preventing the liquid in the discharge port from flowing back into the second chamber. Thus, when the conveying body stops working, the backflushing module transports the liquid in the second chamber to the discharge port through the drain pipe. The swirling liquid can better flush the discharge port and the conveying body, reducing the deposition of solid particles in the discharge port and the conveying body. This helps to avoid overload or blockage of the conveying device during the next startup due to solid particle deposition.

[0021] Optionally, the conveying body includes a housing, a rotary drive, and an impeller. The discharge port is disposed on the housing, and a conveying channel communicating with the discharge port is disposed inside the housing. An inlet is disposed at one end of the housing away from the discharge port. A spiral groove is formed on the inner wall of the inlet, and the inlet communicates with the conveying channel through the spiral groove. The impeller is disposed inside the inlet, and the periphery of the impeller extends to the space between the inlet and the conveying channel. The rotary drive is disposed on the housing, and one end of the rotary drive extends to the inlet and is connected to the impeller.

[0022] By adopting the above technical solution, the rotary drive component drives the impeller to rotate, and the rotation of the impeller causes the abrasive waste liquid to flow. The spiral grooves opened on the inner wall of the inlet allow the abrasive waste liquid to flow into the conveying channel along the spiral grooves when entering the inlet, which plays a guiding role, allowing the abrasive waste liquid to enter the conveying channel more smoothly and improving the conveying efficiency. At the same time, the conveying channel is connected to the outlet, ensuring that the abrasive waste liquid can be smoothly output from the outlet, realizing the effective conveying of the abrasive waste liquid. Furthermore, since the circumference of the impeller extends between the inlet and the conveying channel, the gap between the impeller and the conveying channel is small, thereby increasing the suction force and facilitating the conveying of abrasive.

[0023] Optionally, a reamer is provided in the feed inlet, the reamer is coaxially arranged with the impeller and connected to the rotary drive component.

[0024] By adopting the above technical solution, since the reamer is coaxially arranged with the impeller and connected to the rotary drive component, the rotary drive component drives the impeller to rotate, which in turn drives the reamer to rotate synchronously. During the process of the abrasive waste liquid entering the conveying body from the inlet, the rotating reamer can crush large particles, blocky or filamentous impurities in the abrasive waste liquid, preventing these large particles from accumulating at the inlet and causing blockages. This ensures that the abrasive waste liquid can smoothly pass through the inlet and enter the conveying channel via the spiral groove, and then be stably conveyed to the buffer module, improving the conveying efficiency and stability of the entire abrasive waste liquid conveying device.

[0025] Optionally, the impeller and the inner wall of the conveying channel are respectively coated with a silicon carbide coating.

[0026] By adopting the above technical solution, silicon carbide coatings are applied to the inner walls of the impeller and the conveying channel. When the abrasive waste liquid flows in the conveying channel and comes into contact with the impeller, the silicon carbide coating can resist the wear of solid particles in the abrasive waste liquid, reduce the wear of the impeller and the inner wall of the conveying channel caused by long-term abrasive impact, thereby extending the service life of the impeller and the conveying channel, ensuring the stable conveying of abrasive waste liquid by the conveying body, and contributing to the overall stable operation of the abrasive waste liquid conveying device.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The buffer module can store liquid, and the backflushing module can transfer the liquid in the buffer module to the conveying body when the conveying body stops working, reducing the deposition of solid particles in the conveying body and avoiding overload or blockage when the conveying body is started again. This is beneficial to the subsequent conveying of abrasive waste liquid and the stable operation of the entire conveying device. 2. Through the cooperation of the filter elements and baffles, the liquid in the abrasive waste liquid can be stored in the second chamber, and solid particles can be prevented from entering the second chamber. This facilitates the normal operation of the subsequent backflushing module, reduces the probability of failure caused by excessive impurities, and improves the stability and service life of the entire abrasive waste liquid conveying device. 3. Through the cooperation of the sliding drive, push plate, float plate and collection component, the collection component can collect magnetic particles in the liquid, reduce the magnetic particle content in the liquid, and when the conveying body stops working, the sliding drive drives the push plate to move. The push plate first contacts the float plate and blocks the clearance groove, and then pushes the liquid through the one-way component to the discharge port and then into the conveying body to prevent solid particles from settling.

[0038] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0039] This application discloses an abrasive waste liquid conveying device.

[0040] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Example 1 Reference Figure 1An abrasive waste fluid conveying device includes a conveying body 1, one end of which is connected to a machine tool grinding box, and the other end of which is connected to a filtration device. This facilitates the conveying of abrasive waste fluid from the machine tool grinding box to the filtration device for treatment, thereby achieving the recycling of the grinding fluid. This design, through a closed conveying system, significantly reduces the risk of waste fluid leakage, minimizes the potential pollution to surrounding soil and water bodies, and further protects the environment.

[0042] It should be noted that the specific design of the machine tool grinding box and the filter device is a conventional technical means for those skilled in the art, and therefore will not be described in detail in the embodiments of this application.

[0043] Reference Figure 2 and Figure 3 The conveying body 1 includes a housing 11, a rotary drive component 12, and an impeller 13. The housing 11 is made of a high-strength, corrosion-resistant metal material, such as stainless steel, to withstand the corrosion and impact of the abrasive waste liquid. The use of corrosion-resistant materials helps extend the equipment's lifespan and reduce waste liquid leakage due to component damage, thereby achieving environmental protection.

[0044] One end of the housing 11 is provided with a feed inlet 111, which is connected to the machine tool grinding box. The other end of the housing 11 is provided with a discharge outlet 112, which is connected to a filter device. A conveying channel 113 is provided inside the housing 11, which is connected to both the discharge outlet 112 and the feed inlet 111. In this embodiment, the discharge outlet 112 has a circular cross-section to facilitate smooth liquid flow.

[0045] Reference Figure 3 and Figure 4 A spiral groove 114 is provided on the inner wall of the feed inlet 111, and the feed inlet 111 is connected to the conveying channel 113 through the spiral groove 114. The design of the spiral groove 114 enables the abrasive waste liquid to flow along the spiral trajectory when entering the feed inlet 111, which plays a guiding role and allows the abrasive waste liquid to enter the conveying channel 113 more smoothly.

[0046] Reference Figure 3 The rotary drive component 12 includes a motor 121 and a drive shaft 122. The motor 121 is mounted on the housing 11, and the drive shaft 122 is rotatably connected to the housing 11. One end of the drive shaft 122 is fixedly connected to the output end of the motor 121, and the other end of the drive shaft 122 extends into the feed inlet 111 and is fixedly connected to the impeller 13. This allows the motor 121 to drive the impeller 13 to rotate through the drive shaft 122, thereby providing power for the conveying of abrasive waste liquid.

[0047] In this embodiment, the drive shaft 122 is connected to the inner wall of the housing 11 by a bearing, so that the drive shaft 122 can rotate on the housing 11. A mechanical seal is provided at the part where the drive shaft 122 passes through the housing 11 to prevent leakage of abrasive waste liquid, avoid pollution of the workshop floor, soil and groundwater, and ensure the occupational health and safety of operators. This is a key technical guarantee for achieving clean production.

[0048] It should be noted that the specific design of the mechanical seal device is a conventional technical means for those skilled in the art, and therefore will not be described in detail in the embodiments of this application.

[0049] The impeller 13 is located inside the feed inlet 111, and its circumference extends between the feed inlet 111 and the conveying channel 113, resulting in a smaller gap between the impeller 13 and the conveying channel 113. This increases the suction force when the impeller 13 rotates, facilitating the conveying of abrasive materials. In this embodiment, the impeller 13 is made of aluminum alloy, which has moderate strength and light weight, reducing the load on the rotating drive component 12 while ensuring structural strength.

[0050] In this embodiment, the inner walls of the impeller 13 and the conveying channel 113 are coated with silicon carbide coatings. Silicon carbide coatings are characterized by high hardness, wear resistance, and corrosion resistance, effectively reducing wear from the abrasive waste liquid on the impeller 13 and the inner walls of the conveying channel 113, thus extending their service life. In other embodiments, the silicon carbide coating can be replaced with a ceramic coating. These coatings are not only wear-resistant but also resistant to chemicals in the waste liquid, reducing the introduction of corrosion products into the environment and lowering the risk of pollution.

[0051] The implementation principle of the abrasive waste liquid conveying device in this application embodiment is as follows: When abrasive waste liquid needs to be treated, the motor 121 is started to drive the impeller 13 to rotate through the transmission shaft 122, providing power for the conveying of abrasive waste liquid. This facilitates the drawing of abrasive waste liquid from the machine tool grinding box into the housing 11 through the inlet 111, and then allows the abrasive waste liquid to sequentially pass through the conveying channel 113 and the outlet 112 into the filtration device for treatment, thus preventing environmental pollution. This closed-loop system ensures that the waste liquid is not discharged externally, and at the same time, the subsequent filtration steps remove harmful substances, enhancing the pollution prevention and control effect.

[0052] Example 2 Reference Figure 3 and Figure 5The difference between this embodiment and embodiment 1 is that a reamer 14 is also provided in the feed inlet 111. The reamer 14 is coaxially arranged with the impeller 13 and fixedly connected to the drive shaft 122. So when the motor 121 drives the impeller 13 to rotate through the drive shaft 122, the reamer 14 also rotates synchronously. This allows the reamer 14 to crush large particles, blocky or filamentous impurities in the abrasive waste liquid and prevent these large particles from accumulating in the feed inlet 111 and causing blockage.

[0053] In this embodiment, the reamer 14 is typically made of high-speed steel, which has high hardness, high wear resistance, and high heat resistance, meeting the requirements for crushing abrasives. The reamer's crushing function promotes the complete decomposition of impurities, facilitating subsequent filtration to remove potential contaminants (such as metal fragments) and reducing solid waste emissions into the environment.

[0054] Example 3 Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that it also includes a cache module 2 and a backflush module 3.

[0055] Specifically, the buffer module 2 includes a buffer box 21 and a filter assembly 22 disposed within the buffer box 21. The buffer box 21 is provided with a first chamber 211 and a second chamber 212. The first chamber 211 has a circular cross-section and is connected to the filter device through a pipe. The center line of the discharge port 112 is arranged along the tangent direction of the circumference of the first chamber 211 and is connected to the first chamber 211.

[0056] When the abrasive waste liquid enters the first chamber 211 from the discharge port 112, the abrasive waste liquid will flow along the circumferential tangent of the first chamber 211, so that the abrasive waste liquid forms a rotating flow in the circular first chamber 211. This rotating flow can prevent the solid particles in the abrasive waste liquid from being deposited at the bottom of the first chamber 211, but instead allow them to continue to move with the rotating liquid.

[0057] Reference Figure 8 and Figure 9 The filter assembly 22 includes a baffle 221 and a filter element 222. The baffle 221 is disposed between the first chamber 211 and the second chamber 212, serving to separate the two chambers. The filter element 222 is disposed between the baffle 221 and the top wall of the buffer tank 21. In this embodiment, the filter element 222 is a filter screen. The mesh size of the filter screen is selected according to the size of the solid particles in the abrasive waste liquid; generally, a filter screen with a smaller pore size is selected, which can effectively filter out most of the solid particles.

[0058] When the abrasive waste liquid enters the first chamber 211 and the liquid surface of the abrasive waste liquid contacts the filter element 222, some of the liquid in the abrasive waste liquid can pass through the filter element 222 and enter the second chamber 212. At this time, the filter element 222 can block the solid particles in the abrasive waste liquid to filter the liquid entering the second chamber 212 from the first chamber 211, so as to prevent solid particles from entering the second chamber 212 and causing damage to subsequent equipment. It can also ensure that the liquid entering the second chamber 212 is relatively pure. In addition, the baffle 221 allows the second chamber 212 to store some liquid, providing conditions for the normal operation of the subsequent backflushing module 3.

[0059] It should be noted that the conveying device in this embodiment will operate at high filtration level for a period of time in the initial state, so that the amount of abrasive waste liquid entering the first chamber 211 is greater than the amount flowing out of the first chamber 211, so as to ensure that the liquid surface of the abrasive waste liquid in the first chamber 211 can contact the filter element 222, thereby ensuring that some liquid can be stored in the second chamber 212.

[0060] Reference Figure 7 and Figure 9 The backflushing module 3 includes a backflushing component 31 and a one-way component 32. The backflushing component 31 is disposed in the second chamber 212, and the one-way component 32 is connected to the second chamber 212 and the discharge port 112, so that the backflushing component 31 can discharge the liquid in the second chamber 212 into the discharge port 112 through the one-way component 32.

[0061] The recoil assembly 31 includes a sliding drive 311 and a pressing member 312. The sliding drive 311 is mounted on the buffer box 21, and the pressing member 312 is slidably disposed within the second chamber 212 and connected to the sliding drive 311. In this embodiment, the sliding drive 311 is a cylinder, thereby facilitating the movement of the pressing member 312 using the sliding drive 311.

[0062] The extrusion member 312 includes a push plate 3121 and a float plate 3122. The push plate 3121 and the float plate 3122 are slidably disposed within the second chamber 212 and conform to the inner wall of the second chamber 212. The push plate 3121 is fixedly connected to the sliding drive member 311. In this embodiment, the float plate 3122 is made of plastic or rubber, allowing it to float on the liquid. The float plate 3122 has a clearance groove 3123, and the push plate 3121 is adapted to fit the float plate 3122.

[0063] When liquid flows from the first chamber 211 into the second chamber 212, the liquid can flow through the relief groove 3123 to the bottom of the float 3122. The float 3122 can move upward as the liquid increases. When the sliding drive 311 drives the push plate 3121 to contact the float 3122, the push plate 3121 can block the relief groove 3123.

[0064] A collection tank 3124 is provided on the float plate 3122, and a through hole is provided on the inner wall of the collection tank 3124 to allow liquid to flow out from the collection tank 3124. A magnetic attractor 3125 is installed inside the collection tank 3124. In this embodiment, the magnetic attractor 3125 is a magnet, which facilitates the attraction of magnetic particles in the liquid, thereby reducing the content of magnetic particles in the liquid. It should be noted that magnetic particles refer to metal particles that can be attracted by a magnet.

[0065] The magnetic 3125 is designed to efficiently remove toxic heavy metals from metal pollutants such as rust. When used in conjunction with subsequent filtration devices, it can effectively prevent toxic heavy metals from entering the environmental chain and protect the ecosystem.

[0066] Reference Figure 7 and Figure 9 When the conveying body 1 (refer to) Figure 6 When the machine stops working, the sliding drive 311 drives the push plate 3121 to move. The push plate 3121 first contacts the float 3122 and blocks the clearance groove 3123, and then continues to push the liquid through the one-way component 32 to the discharge port 112 and then into the conveying body 1.

[0067] The one-way component 32 includes a drain pipe 321 and a one-way valve 322 disposed on the drain pipe 321. One end of the drain pipe 321 is connected to the second chamber 212, and the other end is tangentially connected to the discharge port 112, allowing liquid to enter the discharge port 112 along the circumferential tangential direction, forming a swirling flow to better flush the discharge port 112 and the conveying body 1, thereby reducing the deposition of solid particles. Furthermore, the one-way valve 322 ensures that liquid can only flow from the second chamber 212 to the discharge port 112, preventing liquid in the discharge port 112 from flowing back into the second chamber 212.

[0068] The implementation principle of the abrasive waste liquid conveying device in this application embodiment is as follows: When the conveying body 1 stops working, the sliding drive component 311 drives the push plate 3121 to move. The push plate 3121 first contacts the float plate 3122 and blocks the clearance groove 3123, and then continues to push the float plate 3122 to move downward. The float plate 3122 and the push plate 3121 cooperate with each other to push the liquid from the drain pipe 321 to the discharge port 112, so that the liquid can enter the discharge port 112 along the circumferential tangential direction of the discharge port 112, forming a vortex, which better flushes the discharge port 112 and the conveying body 1, so as to reduce the deposition of solid particles.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
