Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater recycling and treatment, and particularly relates to a wastewater recycling and treatment device for a concrete mixing plant. Background Art

[0002] At present, the recycling of concrete wastewater is of great significance in realizing resource recycling and reducing environmental pollution. When recycling and treating the wastewater generated by a mixing plant, the wastewater is first subjected to pretreatment such as precipitation, and then the wastewater is recycled and treated after the pretreatment is completed. In the specific recycling and treatment process, different types of chemicals need to be added to the wastewater. However, in the existing devices, it is impossible to achieve electro-controlled automation to add different types of chemicals as needed, and it is also impossible to mix the chemicals in advance when adding the chemicals. If there is a large amount of particle accumulation inside the chemicals, it will cause stratification and affect the normal use of the chemicals; in addition, when there is too much impurity accumulation at the upper end of the preliminary treatment end, it is impossible to separately treat the impurity accumulation at the upper end of the preliminary treatment end, and the overall equipment needs to be disassembled during cleaning, which will reduce the efficiency of wastewater recycling and processing in the later stage.

[0026] In addition, the present invention also uses the liquid spraying mechanism to recycle and treat the wastewater. Specifically, according to the requirements during the reaction of the wastewater in the filtration cavity, the liquid spraying mechanism adds the corresponding reaction liquid as needed, and can also mix the reaction liquid to be added before adding it, and then add the reaction liquid after mixing, avoiding the occurrence of particle precipitation inside the reaction liquid before adding, which may lead to the treatment of the wastewater by the added reaction liquid not achieving the expected effect, resulting in the need for rework in the later stage.

[0027] On this basis, the present invention provides a structural basis for the rapid contact reaction between wastewater and reaction liquid through a circulation processing mechanism, thereby increasing the efficiency of wastewater reaction treatment. In addition, the moving loop frame and filter screen that move in a cycle can also salvage and adsorb the impurities condensed during the wastewater reaction process, and the filter screen can automatically remove the impurities after the adsorption of impurities is completed, ensuring that the filter screen can be used for a long time.

[0045] In this technical solution, a wastewater recycling and treatment device for a concrete mixing plant, as Figure 1-2 shown, includes a processing box 1. On both sides of the top end of the processing box 1, a feed pipe 5 is provided. The feed pipe 5 is communicated with the inside of the processing box 1 for introducing wastewater into the processing box 1. A discharge through groove 9 is provided at the bottom end of the processing box 1. A multi-way discharge solenoid valve 7 is provided at the bottom end of the discharge through groove 9 for discharging the treated wastewater. A stable bottom frame 6 is installed at the bottom end of the processing box 1 for discharging the treated wastewater.

[0046] As Figure 1 shown, the wastewater recycling and treatment device further includes: an extrusion mechanism 2 and a liquid spraying mechanism 3.

[0047] Among them, asFigure 2 As shown in the figure, the extrusion mechanism 2 includes an arc-shaped extrusion plate 205 arranged at the upper end inside the processing frame 1 through a support assembly. The arc-shaped extrusion plate 205 divides the internal space of the processing frame 1 into two cavities with upper and lower structures. Among them, the cavity located above is configured as an extrusion cavity 13, and the cavity located below is configured as a filtration cavity 14. On this basis, a number of liquid passing holes are densely distributed on the arc-shaped extrusion plate 205, which are used to filter the wastewater introduced into the extrusion cavity 13 through the feed pipe 5, and send the liquid and part of the solid impurities into the filtration cavity 14, and the remaining solid impurities are left on the arc-shaped extrusion plate 205. In addition, the extrusion mechanism 2 further includes a movable extrusion frame 204 arranged above the arc-shaped extrusion plate 205 through a power assembly. The bottom end of the movable extrusion frame 204 is of an arc-shaped structure and is adapted to the top structure of the arc-shaped extrusion plate 205. On the basis that the power assembly provides rotational power for the movable extrusion frame 204, the movable extrusion frame 204 and the arc-shaped extrusion plate 205 cooperate with each other to crush the solid impurities left on the arc-shaped extrusion plate 205. On this basis, a through hole is also opened in the middle of the arc-shaped extrusion plate 205, and a discharge assembly is arranged inside the through hole, which is used to discharge the crushed solid impurities.

[0048] Specifically, as Figure 2 shown, in the extrusion mechanism 2, the power assembly includes a single-phase motor 201 installed at the top of the outer wall of the processing frame 1. The output end of the single-phase motor 201 penetrates the processing frame 1 and extends into the interior of the processing frame 1. A rotating rod 202 with a rectangular cross-section is installed at the output end of the single-phase motor 201.

[0049] The power assembly further includes a rectangular opening opened in the middle of the top end of the movable extrusion frame 204. The rotating rod 202 is fitted through the rectangular opening and extends into the interior of the movable extrusion frame 204. Its fitting structure is as Figure 4-5 shown. Among them, a limiting plate 221 is arranged at one end of the rotating rod 202 located inside the movable extrusion frame 204. In addition, a fixing spring 203 is sleeved on the outer wall of the rotating rod 202. The top end of the fixing spring 203 is connected to the top end of the inner cavity of the movable extrusion frame 204, and the bottom end of the fixing spring 203 is connected to the top end of the limiting plate 221.

[0050] In addition, as Figure 2-3 、 Figure 6-7 shown, in the extrusion mechanism 2, the discharge assembly includes a movable tube 220 movably arranged in the through hole, and the movable tube 220 extends into the interior of the filtration cavity 14. An annular sealing strip 8 is arranged on the outer side of the bottom end of the movable tube 220. In addition, the movable tube 220 is of a hollow structure, and two recovery openings 218 are correspondingly opened on the side wall of the movable tube 220 near the top end, and two moving long grooves 222 are correspondingly opened between the two recovery openings 218 of the movable tube 220.

[0051] The emission assembly further includes a movable blocking cylinder 219 movably installed at the top end of the inner cavity of the movable pipe 220, and the movable blocking cylinder 219 is located at the position of the recovery through port 218. The top end of the movable blocking cylinder 219 is installed with a movable mounting rod 216. A notch is opened at the top end of the movable mounting rod 216, and a limiting electromagnet 214 is installed inside the notch. A movable groove 213 is opened at the bottom end of the movable extrusion frame 204, and a magnetic plate 10 is installed at the top end of the inner cavity of the movable groove 213. The top end of the movable mounting rod 216 extends into the inside of the movable groove 213. Moving sliders 212 are installed on both sides of the top end of the movable mounting rod 216. A pulling spring 215 is installed at the bottom end of each moving slider 212. In addition, discharge ports 15 are opened around the top end of the movable blocking cylinder 219. Rubber ring strips are provided around the discharge ports 15, and the rubber ring strips are in contact with and pressed against the inner wall top end of the movable pipe 220. The movable mounting rod 216, the discharge ports 15 and the rubber ring strips do not interfere with each other. In addition, two moving blocks 223 are provided on the circumferential outer wall of the movable blocking cylinder 219 corresponding to two moving long grooves 222. The moving blocks 223 are slidably connected to the moving long grooves 222, and when the movable blocking cylinder 219 moves, it drives the moving blocks 223 to slide inside the moving long grooves 222. When the movable blocking cylinder 219 rotates, through the engagement of the moving blocks 223 with the inner cavity of the moving long grooves 222, it drives the movable pipe 220 to rotate.

[0052] On this basis, the limiting electromagnet 214 is subjected to waterproof treatment. A control panel is installed on the front outer wall of the treatment frame 1, and the limiting electromagnet 214 is electrically connected to the control panel.

[0053] As Figure 6 shown, the emission assembly further includes storage and release grooves 11 opened on both sides of the bottom end of the movable extrusion frame 204, and a movable scraping strip 206 is movably installed inside each storage and release groove 11. An adsorption magnetic strip 217 is coated inside the movable scraping strip 206. In addition, the emission assembly further includes a connecting top rod 208. The connecting top rod 208 has an arched structure, and one end of the connecting top rod 208 penetrates through the movable extrusion frame 204 and is connected to the movable scraping strip 206, and the other end penetrates through a moving through port opened at the top end of the movable groove 213 and is connected to the top end of the moving slider 212. On this basis, a sealing sleeve is sleeved outside the end of the connecting top rod 208 far from the moving slider 212, and the bottom end of the sealing sleeve is connected to the top end of the movable extrusion frame 204.

[0054] As Figure 2 、 Figure 8-9As shown in the figure, in the extrusion mechanism 2, the support assembly includes a number of installation sliding grooves 207 opened around the inner wall of the processing frame 1. An installation slider 209 is slidably installed inside each installation sliding groove 207. One end of the installation slider 209 away from the installation sliding groove 207 abuts against the bottom end of the arc-shaped extrusion plate 205. An installation spring 210 is provided at the bottom end of the installation slider 209. One side bottom end of the inner wall of the installation sliding groove 207 is provided with a touch switch 211. The touch switch 211 is electrically connected to the control panel. A sealing layer is provided outside the installation sliding groove 207.

[0055] Based on the above embodiment, when recycling and treating wastewater, wastewater is added into the processing frame 1 through the feed pipe 5, and the single-phase motor 201 is started to drive the rotating rod 202 to rotate. The movable extrusion frame 204 is driven to rotate through the cooperation of the rotating rod 202 and the rectangular opening. When the wastewater passes through the arc-shaped extrusion plate 205, some impurities in it will remain on the arc-shaped extrusion plate 205. When the movable extrusion frame 204 rotates, the impurities remaining on the upper end of the arc-shaped extrusion plate 205 will be frictionally broken. When the impurities accumulated at the top end of the arc-shaped extrusion plate 205 are too much, an extrusion driving force will be generated on both the arc-shaped extrusion plate 205 and the movable extrusion frame 204 at the same time. When the movable extrusion frame 204 moves upward, the fixed spring 203 is stretched. Since the elastic strength of the fixed spring 203 is greater than that of the installation spring 210, through its reaction force, the adhesion between the movable extrusion frame 204 and the arc-shaped extrusion plate 205 is increased.

[0056] Meanwhile, when there is too much impurity accumulated at the upper end of the arc-shaped extrusion plate 205, the weight of the arc-shaped extrusion plate 205 will increase. Since the fixing spring 203 is in a stretched state, when the arc-shaped extrusion plate 205 moves downward, it drives the movable extrusion frame 204 to move downward through the elastic extrusion force. At this time, the movable extrusion frame 204 drives the movable blocking cylinder 219 to move downward. At this time, the movable tube 220 is not restricted by the movable blocking cylinder 219 and moves downward due to its own gravity. The annular sealing strip 8 at the bottom end of the movable tube 220 starts to rub against the discharge through groove 9, and makes the movable tube 220 gradually stop falling and contact the bottom of the discharge through groove 9. The accumulated impurities will make the arc-shaped extrusion plate 205 continue to move downward, then the middle part of the arc-shaped extrusion plate 205 will pass through the recovery through port 218, exposing the recovery through port 218 at the top end of the arc-shaped extrusion plate 205. When the arc-shaped extrusion plate 205 moves downward, the arc-shaped extrusion plate 205 will squeeze the installation slider 209, causing the installation slider 209 to move downward in the installation chute 207 and squeeze the installation spring 210, so that the installation slider 209 contacts the touch switch 211, triggering the control panel to activate the limit electromagnet 214. At this time, the circuit of the limit electromagnet 214 is disconnected, making the limit electromagnet 214 lose magnetism. Then the pulling spring 215 drives the moving slider 212 and the movable installation rod 216 to move downward, and drives the movable blocking cylinder 219 to move downward, making the inside of the recovery through port 218 lose any blockage. Specifically, as Figure 10 shown, the impurities accumulated at the top end of the arc-shaped extrusion plate 205 are dropped into the inside of the movable tube 220 through the exposed recovery through port 218 and fall into the discharge through groove 9, and then the multi-way discharge solenoid valve 7 is activated to discharge the impurities. When the moving slider 212 moves downward, it drives the connecting top rod 208 to move downward and drives the moving scraping strip 206 to move downward, so that the bottom end of the moving scraping strip 206 contacts the top end of the arc-shaped extrusion plate 205. Through the rotation of the movable extrusion frame 204, the moving scraping strip 206 slides on the top end of the arc-shaped extrusion plate 205, gathering the impurities at the top end of the arc-shaped extrusion plate 205 towards the side of the recovery through port 218, increasing the efficiency of impurity treatment.

The end of the movable ejector rod 305 away from the moving inclined plate 304 penetrates through the processing frame 1 and extends into the fixed frame 301, and an extrusion plate 307 is connected to the end of the movable ejector rod 305 located inside the fixed frame 301. An extrusion airbag 302 is installed on the side of the extrusion plate 307 away from the movable ejector rod 305. One end of the extrusion airbag 302 is connected to a fixing plate 309. A multi-way solenoid valve 310 is provided on the side of the fixing plate 309 away from the extrusion airbag 302. The multi-way solenoid valve 310 is electrically connected to the control panel. An air path is opened inside the fixing plate 309, and air holes are opened on both sides and the bottom end of the fixing plate 309. Among them, the extrusion airbag 302 and the multi-way solenoid valve 310 are respectively communicated with the air holes on both sides of the fixing plate 309, and the air hole at the bottom end of the fixing plate 309 is connected to a fixed pipe 312.

[0059] On this basis, the air supply component further includes a stable sliding rod 311 provided on the inner wall of the fixed frame 301. A stable sliding hole is opened at the bottom end of the extrusion plate 307, and the stable sliding rod 311 passes through the inside of the stable sliding hole. One end of the stable sliding rod 311 is connected to the bottom end on one side of the fixing plate 309.

[0060] In addition, as Figure 8 shown, the air supply component further includes an intake check valve 12 provided on one side of the top end of the storage frame 308, and the intake end of the intake check valve 12 is communicated with the fixed pipe 312. A delivery air pipe 313 is provided inside the storage frame 308. A plurality of nozzles 314 are equidistantly installed at the bottom end of the delivery air pipe 313. The top end of the delivery air pipe 313 is connected to the outlet end of the intake check valve 12; discharge through openings 316 are opened at positions on the inner wall of the processing frame 1 corresponding to each discharge check valve 315. Among them, one end of the discharge check valve 315 away from the storage frame 308 is connected to the inner wall of the discharge through opening 316. A one-way rubber valve is installed on the side of the discharge through opening 316 away from the discharge check valve 315. The one-way rubber valve is made of rubber material and has a concentric circle structure.

[0061] Based on the above embodiment, in the process of recycling the wastewater in the filter chamber 14, different reaction liquids are first added to the storage frame 308. Since the above-mentioned movable extrusion frame 204 is always rotating, the movable inclined plate 304 will be pushed by pushing the cone block 303, which will cause the movable inclined plate 304 to move to the side away from the movable extrusion frame 204, and squeeze the return spring 306, and drive the movable push rod 305 to move. When the movable push rod 305 moves, it drives the extrusion plate 307 to move and squeeze the extrusion airbag 302. When the extrusion plate 307 moves, it slides outside the stabilizing slide bar 311 to increase the stability of the extrusion plate 307 when it moves. When the extrusion airbag 302 is squeezed, the air in the extrusion airbag 302 is transported to the inside of the fixed plate 309.

[0062] Specifically, when the corresponding reaction liquid needs to be added, the corresponding multi-way solenoid valve 310 is started through the control panel. At this time, the multi-way solenoid valve 310 connects the fixed plate 309 with the fixed tube 312, and the gas can only pass from the fixed plate 309 to the fixed tube 312, so that the squeezed air is transported to the inside of the fixed tube 312, and the gas is transported to the inside of the transport gas pipe 313, and finally the gas is transported to the inside of the storage frame 308 through the nozzle 314. When the gas moves from bottom to top through the nozzle 314, the reaction liquid in the storage frame 308 is mixed first to avoid the reaction liquid The solid particles inside will sink to the bottom, affecting the normal use of the reaction liquid. When the gas is transported to the storage frame 308, the air pressure inside the storage frame 308 will increase. The larger air pressure will cause the one-way rubber valve in the discharge port 316 to be stretched open, thereby spraying the reaction liquid into the processing frame 1. When the extrusion airbag 302 is reset by the release force of the reset spring 306, the multi-way solenoid valve 310 is controlled by the control panel to connect the fixed plate 309 with the outside world, and the extrusion airbag 302 absorbs the outside air through the multi-way solenoid valve 310 to reset, thereby realizing a cyclic operation.

[0063] When a certain type of reaction liquid does not need to be added, the corresponding multi-way solenoid valve 310 is started through the control panel. At this time, the multi-way solenoid valve 310 connects the fixed plate 309 with the outside world, and the squeezed air is transported to the outside world. When the squeezing airbag 302 is reset by the release elastic force of the reset spring 306, the squeezing airbag 302 absorbs the outside air through the multi-way solenoid valve 310 to reset. In addition, in this process, the one-way rubber valve is not used and opened, so that the waste water cannot contact the discharge one-way valve 315, ensuring that the discharge one-way valve 315 will not be corroded, thereby ensuring the life of the discharge one-way valve 315 during use.

[0064] In this technical solution, if Figure 2 , Figure 12As shown in the figure, the wastewater recycling and treatment device further includes a circulation treatment mechanism 4. Among them, the circulation treatment mechanism 4 includes a thread layer 405 partially opened on the circumferential outer wall of the movable pipe 220, a rotating sleeve 408 sleeved on the circumferential outer wall of the movable pipe 220 and threadedly connected to the thread layer 405, and a movable ring frame 401 connected to the circumferential outer wall of the rotating sleeve 408 through a connecting component. A plurality of filter holes are opened on the movable ring frame 401, and a filter screen 402 is provided in each filter hole. The filter screen 402 is made of rubber material. A fixed electromagnetic block 403 is installed at the bottom end of each filter screen 402, and a sealing layer is coated on the outside of the fixed electromagnetic block 403. The fixed electromagnetic block 403 is electrically connected to the control panel. Correspondingly, fixed iron blocks 406 are installed at the bottom ends of the inner walls around the treatment frame 1 through support rods. The fixed iron blocks 406 are of a hollow structure, and an induction switch is installed inside the fixed iron blocks 406. The induction switch is electrically connected to the control panel.

[0065] In addition, as Figure 12 shown, the circulation treatment mechanism 4 further includes a movable sleeve provided at the bottom end of the movable pipe 220 and having a rectangular cross-section. Movable scraping strips 407 are installed around the outer wall of the movable sleeve. The bottom end of the movable scraping strip 407 cooperates with the bottom end of the inner wall of the treatment frame 1. The bottom end of the movable pipe 220 and the movable sleeve are rectangular in a top view, as Figure 13 shown, and the annular sealing strip 8 is located below the movable sleeve. Moving guide strips 404 are installed in the middle of both sides of the inner wall of the treatment frame 1. Docking sliding openings are opened on both sides of the movable ring frame 401, and the docking sliding openings are slidably connected to the moving guide strips 404 in a matching manner.

[0066] As Figure 14 shown, in the circulation treatment mechanism, the connecting component includes an installation ring groove 411 provided on the circumferential inner wall of the movable ring frame 401. An installation ring strip 409 is slidably installed inside the installation ring groove 411. One end of the installation ring strip 409 away from the installation ring groove 411 is connected to the circumferential outer wall of the rotating sleeve 408. Two fixing openings are correspondingly opened on the inner wall of the installation ring groove 411, and a working electromagnetic block 413 is installed in each fixing opening through a support frame. The working electromagnetic block 413 is electrically connected to the control panel. And an activity plate 415 is movably provided on one side close to the installation ring strip 409 in each fixing opening. A limiting convex block 412 is provided on the side of the activity plate 415 away from the working electromagnetic block 413. A plurality of limiting notches 410 are equidistantly opened on the circumferential outer wall of the installation ring strip 409. The limiting convex block 412 is fitted and docked with the limiting notch 410. In addition, an iron sheet is provided on the side of each activity plate 415 away from the limiting convex block 412. Connecting springs 414 are provided on both sides of the iron sheet. One end of the connecting spring 414 away from the activity plate 415 is connected to the support frame supporting the working electromagnetic block 413.

[0067] Based on the above embodiments, as Figure 12As shown, when the movable tube 220 rotates, it drives the threaded layer 405 to rotate. Through the engagement of the threaded layer 405 and the rotating sleeve 408, the rotating sleeve 408 is driven to move downward, and the movable ring frame 401 is driven to move downward, thereby driving the filter screen 402 to move downward. At this time, the connecting sliding port slides outside the moving guide bar 404, increasing the stability and guiding property when the movable ring frame 401 moves. When the movable ring frame 401 moves to the inner bottom end of the treatment box 1, the fixed electromagnet 403 contacts the upper end of the fixed iron block 406, triggering the induction switch to trigger the single-phase motor 201 to reverse through the control panel. As a result, the movable tube 220 will reverse, and drive the rotating sleeve 408 to move upward through the threaded layer 405, and drive the movable ring frame 401 and the filter screen 402 to move upward. Through the up and down cyclic movement of the movable ring frame 401 and the filter screen 402, the wastewater inside the treatment box 1 is surging, enabling the reaction liquid to react with the wastewater faster.

[0068] When the movable ring frame 401 and the filter screen 402 do not need to move, the working electromagnet 413 is started through the control panel, so that the working electromagnet 413 generates magnetism, magnetically attracts the iron sheet installed on one side of the movable plate 415, drives the movable plate 415 and the limiting convex block 412 to move, and separates the limiting convex block 412 from the inside of the limiting notch 410. When the movable plate 415 moves, the connecting spring 414 is compressed. Driven by the compressed connecting spring 414, the movable plate 415 and the limiting convex block 412 move away from the limiting notch 410. At this time, when the rotating sleeve 408 rotates, it drives the mounting ring strip 409 to rotate inside the mounting ring groove 411, and will not drive the movable ring frame 401 to rotate. If the limiting convex block 412 needs to be reset, the power supply of the working electromagnet 413 is disconnected, so that the working electromagnet 413 loses magnetism, and loses the magnetic attraction ability with the movable plate 415. The connecting spring 414 releases the elastic force, making the limiting convex block 412 dock with the limiting notch 410 again.

[0069] After the reaction is completed, the limit electromagnet block 214 is activated through the control panel, so that the limit electromagnet block 214 generates magnetic force and starts to move upward to fit with the magnetic plate 10. The upward movement of the limit electromagnet block 214 will drive the movable mounting rod 216 and the movable blocking cylinder 219 to move upward at the same time, and then drive the movable pipe 220 to move upward. At this time, the annular sealing strip 8 disengages from the discharge through groove 9. At this time, the wastewater inside the treatment box 1 is discharged through the discharge through groove 9. After the discharge is completed, the fixed electromagnet block 403 is activated to generate magnetism. The fixed electromagnet block 403 contacts the fixed iron block 406 and generates magnetic attraction. When the filter screen 402 moves upward, the magnetic attraction between the fixed electromagnet block 403 and the fixed iron block 406 will fix the bottom end of the filter screen 402 so that it will not move, causing the filter screen 402 to deform, enlarging the filter holes inside the filter screen 402, and the impurities accumulated on the filter screen 402 will fall off and then be discharged through the discharge through groove 9. Subsequently, the fixed electromagnet block 403 is disconnected through the control panel, causing the fixed electromagnet block 403 to lose magnetism, so that the filter screen 402 can continue to be used.

[0070] Generally speaking, when the extrusion mechanism 2 is used to preliminarily treat the wastewater, it can extrude and crush the softer impurities in the wastewater, avoiding the accumulation of softer and larger impurities, which may cause blockage when the whole wastewater recycling and treatment device is used to recycle and treat the wastewater. In addition, when too many impurities accumulate in the extrusion cavity 13, the device can, on the basis of stopping the liquid transportation, use the cooperation between the power component and the discharge component in the extrusion mechanism 2 to separately treat the accumulated impurities, avoiding the reduction of the efficiency of wastewater recycling and treatment caused by the accumulation of impurities.

[0071] In addition, the present invention also uses the liquid spraying mechanism 3 to recycle and treat the wastewater. Specifically, according to the requirements of the wastewater reaction in the filtration cavity 14, the corresponding reaction liquid is added as needed by the liquid spraying mechanism 3, and the reaction liquid to be added can be mixed when adding the reaction liquid, and then added after mixing, avoiding the situation of particle precipitation inside the reaction liquid before adding, which may lead to the situation that the treated wastewater by the added reaction liquid fails to meet the expected effect, resulting in the need for rework later.

[0072] On this basis, the present invention provides a structural basis for the rapid contact reaction between the wastewater and the reaction liquid through the circulation treatment mechanism 4, thereby increasing the efficiency of wastewater reaction treatment. In addition, the circulating movable ring frame 401 and the filter screen 402 can also salvage and adsorb the impurities coagulated during the wastewater reaction process, and the filter screen 402 can also remove the impurities by itself after adsorbing the impurities, ensuring that the filter screen 402 can be used for a long time.

[0073] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
