Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sludge transportation, and in particular to a sludge transfer mechanism for an electric sludge transport vehicle. Background Art
[0002] Many sewage treatment plants do not have the final sludge disposal capabilities (such as incineration, landfill, and land use) and usually need to use sludge transport trucks to transport the sludge to centralized treatment centers and professional disposal units. Therefore, sludge transport trucks are an indispensable part of the sludge management system.
[0003] The sludge after preliminary treatment has a high water content. Even the dehydrated sludge usually has a water content between 60% and 85%. This makes the sludge after preliminary treatment susceptible to vehicle bumps and shaking during transportation, resulting in sedimentation, causing the sludge at the bottom to continue to deposit and adhere, making it difficult to unload. The water content of the surface sludge is further increased, which increases the fluidity of the surface sludge and increases the risk of sludge leakage during transportation. At the same time, some sludge contains a certain amount of sand. The sedimentation and shaking during transportation can easily cause wear on the bottom of the sludge transfer box, affecting the service life and sealing of the sludge transfer box. In addition, organic sludge is easily fermented during transportation, producing malodorous gases such as hydrogen sulfide and ammonia, which pollute the environment and may endanger health. If unloading is performed after transportation, it is easy to cause harm to the staff. Therefore, a sludge transfer mechanism for an electric sludge transport vehicle is proposed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This solution uses the magnetic vibration component of the vibration expansion plate to drive the vibration membrane to vibrate at high frequency during loading, forcing the sludge to quickly stratify (heavy liquid sinks, light liquid floats), reducing mixing and shaking during transportation. During bumpy transportation, the driving impeller drives the bidirectional threaded shaft to rotate, causing the vibration expansion plate to move back and forth on the sludge surface, amplifying the shaking amplitude, promoting rapid compaction and deposition of the sludge at the bottom, and maintaining the light liquid flow state on the surface. After the compacted layer is stable, it no longer shakes, avoiding continuous impact on the bottom and side walls of the sludge transfer box, and significantly reducing equipment wear.
[0018] 2. Through the setting of sludge treatment components, this solution can sprinkle quicklime powder onto the surface light liquid after stratification. Quicklime releases heat violently when it comes into contact with water (the temperature sensor of the monitoring head adjusts the dosage in real time), instantly killing pathogens. The alkaline environment completely inhibits microbial activity, terminates the fermentation process, avoids the generation of toxic gases, and achieves preliminary treatment of the sludge.
[0019] 3. This solution uses a breaker plate to extract light liquid (with good fluidity) from the surface during unloading. The remaining compacted sludge is dumped through a hydraulic mechanism. The self-adjusting rack-linked breaker plate squeezes the packaging film to loosen the compacted sludge from the bottom, avoiding manual digging and improving the efficiency of sludge unloading.

[0033] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.
[0034] Example, see Figures 1 to 10 A sludge transfer mechanism for an electric sludge transport vehicle includes a sludge transport vehicle seat 1 and a sludge transfer box 2 for loading sludge. A retaining frame 7 is installed on the inner end surface of the sludge transfer box 2. A guide rail 8 is fixedly connected to the inner end surface of the sludge transfer box 2. The guide rail 8 is connected to a plurality of breaking plates 11 through a self-adjusting component. A packaging film 12 is provided on the breaking plate 11.
[0035] Furthermore, the sludge transport vehicle seat 1 is connected to the sludge transfer box 2 through a hydraulic lifting mechanism, the end of the sludge transfer box 2 is rotatably connected to the packaging door 4 through a hinge, the sludge transport vehicle seat 1 is connected to the packaging door 4 through a hydraulic rotation mechanism 3, the top sealing seat 5 is rotatably mounted with a sewage treatment valve cover 6, the top sealing seat 5 is installed with an air pressure sensor for monitoring the sealing state of the sludge transfer box 2, the self-adjusting component includes a self-adjusting rack 9 slidably arranged in a guide rail 8, the self-adjusting rack 9 is meshed with an adjusting gear ring 10, the adjusting gear ring 10 is fixedly connected to the breaking plate 11 through a pin shaft, the pin shaft is rotatably connected to the sludge transfer box 2, and the packaging film 12 is fixedly assembled with the retaining frame 7;
[0036] It should be noted that: the self-adjusting rack 9 is controlled to slide in the guide rail 8, so that the multiple adjustment gear rings 10 are deflected under the action of the movement of the self-adjusting rack 9. The rotation of the adjustment gear ring 10 drives the destruction plate 11 to rotate, squeezing the flat packaging film 12, so that the overall structure of the sludge deposited and compacted on the packaging film 12 is destroyed from the bottom, making it easier for workers to quickly unload the sludge deposited at the bottom;
[0037] The above benefits are: the shaking during transportation can be used to perform preliminary stratification of the sludge, so that the sludge deposited at the bottom can be further dehydrated and compacted, thus achieving pretreatment of the sludge during transportation;
[0038] A plurality of symmetrically arranged mounting grooves are provided on the inner side wall of the sludge transfer box 2. A vibration seat 13 is connected to the inner side wall of the mounting groove. The vibration seat 13 is connected to a vibration membrane 16 through a magnetic vibration component. The top of the sludge transfer box 2 is connected to a top sealing seat 5. Two driving impellers 17 are provided on the top sealing seat 5. The driving impellers 17 are connected to a redirecting component through a rotating shaft. The redirecting component is connected to a bidirectional threaded shaft 21. The bidirectional threaded shaft 21 is connected to a moving seat 22 through a fixing button 23. The moving seat 22 is connected to a monitoring head 25 through a lifting column. The outer side wall of the lifting column is slidably connected to a vibration expansion plate 26.
[0039] Furthermore, the magnetic vibration assembly consists of a permanent magnet seat 14 and a magnetic vibration coil 15. The magnetic vibration coil 15 is slidably sleeved on the permanent magnet seat 14 through a magnetic vibration ring. The permanent magnet seat 14 is fixedly connected to the vibration seat 13. The magnetic vibration coil 15 is connected to the vibration membrane 16. The sludge transfer box 2 is fixedly assembled with the top sealing seat 5. The top sealing seat 5 is rotatably connected to the driving impeller 17 through a rotating shaft. The outer wall of the rotating shaft is fixedly connected to a fixed shaft seat 18. A plurality of through holes are opened on the top of the fixed shaft seat 18. The fixed shaft seat 18 is connected to a control valve pipe through the through hole. The redirection assembly includes a vertical bevel gear 19 fixed to the end of the rotating shaft. The vertical bevel gear The gear 19 is meshed with a transverse bevel gear 20, which is fixedly connected to a bidirectional threaded shaft 21. A guide groove rotatably connected to the bidirectional threaded shaft 21 is provided at the bottom end of the top sealing seat 5. The threaded groove on the bidirectional threaded shaft 21 is slidably connected to a movable seat 22 via a fixing button 23. The movable seat 22 is slidably connected to the guide groove. The movable seat 22 is fixedly connected to a monitoring head 25 via a lifting column. A temperature sensor is provided in the monitoring head 25. An adjustment spring 24 is sleeved on the outer wall of the lifting column. The two ends of the adjustment spring 24 are respectively fixedly connected to the movable seat 22 and the vibration expansion plate 26.
[0040] The adjustment spring 24 is used to adjust the up and down movement of the vibration expansion plate 26 when the sludge liquid level is different. Under the elastic force of the adjustment spring 24, the vibration expansion plate 26 will be relatively pressed against the sludge liquid surface.
[0041] It should be noted that: during the sludge loading process, alternating current is applied to the magnetic vibration coil 15 in the vibration seat 13, so that the magnetic vibration ring where the magnetic vibration coil 15 is located has a constantly changing magnetic field, so that magnetic attraction and magnetic repulsion are continuously generated between the magnetic vibration coil 15 and the permanent magnet seat 14, causing the magnetic vibration coil 15 to slide at high frequency in the vibration seat 13 through the magnetic vibration ring. The continuous displacement change will drive the vibration membrane 16 to vibrate at high frequency. The vibration of the vibration membrane 16 will act on the loaded sludge, so that the sludge will produce a certain stratification effect under the action of vibration;
[0042] As the sludge transport vehicle seat 1 bumps and shakes during travel, the sludge in the sludge transfer box 2 will also shake along with it, and the shaking of the sludge itself will further cause the sludge to appear in layers. At the same time, during travel, the driving impeller 17 will rotate under the action of the airflow, and the rotation of the driving impeller 17 will drive the vertical bevel gear 19 to rotate through the rotating shaft, and the rotation of the vertical bevel gear 19 will drive the transverse bevel gear 20 to rotate, and then drive the two-way threaded shaft 21 to rotate, and the moving seat 22 will slide in the thread groove on the two-way threaded shaft 21 through the fixing button 23, realizing the reciprocating movement of the moving seat 22 on the two-way threaded shaft 21, and the moving The movement of the seat 22 will drive the expansion plate 26 to move together. The movement of the expansion plate 26 will increase the shaking amplitude of the surface liquid of the sludge, so that the overall shaking of the sludge is amplified, which is convenient for strengthening the stratification effect of the sludge during driving. As the stratification proceeds, the position of the bottom of the sludge will quickly settle and compact, so that the bottom of the sludge tends to be stable in the subsequent process. Only the surface of the entire sludge is in a relatively shaking state, avoiding wear of the bottom of the sludge transfer box 2 during the continuous shaking of the sludge. The surface liquid of the sludge is light liquid, contains less sand and gravel, and has little pressure on the side wall of the sludge transfer box 2, which also reduces the shaking wear of the side wall of the sludge transfer box 2.
[0043] At the same time, the driving impeller 17 is subjected to a constant airflow direction during its rotation. Under this rotation direction, the bottom of the driving impeller 17 is in a state of negative pressure. After the sludge is stratified to a certain extent, the bubbles in the sludge are basically discharged under the action of shaking, and the control valve tube on the fixed shaft seat 18 is opened to allow the gas in the sludge transfer box 2 to be discharged through the through hole on the fixed shaft seat 18. The sludge transfer box 2 will subsequently be in a relatively low-pressure state, and then the control valve tube on the fixed shaft seat 18 is closed. The air pressure sensor in the top sealing seat 5 will monitor the air pressure state in the sludge transfer box 2 in real time. Due to the large gas flow rate and pressure outside the vehicle, if the box leaks, the external high-pressure airflow will quickly enter the sludge transfer box 2, and the air pressure sensor will quickly detect it and issue an alarm.
[0044] The advantages of the above are as follows: the magnetic vibration assembly can be used in conjunction with the vibration expansion plate 26 to vibrate and shake the sludge, so that the sludge is quickly separated into upper and lower layers during transportation, thereby preventing the bottom of the sludge from being worn during transportation. At the same time, the impeller 17 is driven to guide the gas in the sludge transfer box 2 to flow out, and the sludge transfer box 2 is maintained in a low pressure state. If the air pressure sensor detects a sudden increase in air pressure (external high-pressure airflow intrusion), an alarm will be immediately issued to indicate that the seal has failed.
[0045] The bottom end of the top sealing seat 5 is provided with two symmetrically arranged storage tanks, the storage tanks are connected to the sealing plates 32, and the sealing plates 32 are fixedly connected to the sludge sterilization chamber 31 through the conveying cylinder. The sludge sterilization chamber 31 is provided with a sludge processing component;
[0046] Furthermore, two symmetrically arranged drive motors 27 are fixedly mounted on the top of the top sealing seat 5. The drive motor 27 is fixedly connected to a spiral conveying blade 28 via a drive shaft. The end of the drive shaft is rotatably connected to the inner end surface of the sludge sterilization chamber 31. The sludge processing assembly includes a plurality of distribution plates 29 fixed to the outer wall of the drive shaft. The end of the distribution plate 29 is fixedly connected to a closed arc plate 30. The sludge sterilization chamber 31 is provided with a plurality of distribution holes. The storage tank of the top sealing seat 5 is filled with quicklime powder.
[0047] It should be noted that: when the sludge is initially treated during transportation, after shaking to produce stratification, the control starts the drive motor 27 to drive the drive shaft to rotate. The rotation of the drive shaft will respectively drive the spiral conveying blades 28 and multiple distribution plates 29 to rotate. The rotation of the spiral conveying blades 28 will continuously transport the quicklime powder in the storage tank of the top sealing seat 5 downward, so that the quicklime powder is dispersed into each distribution plate 29. As the distribution plate 29 rotates in the sludge sterilization chamber 31, the falling quicklime powder will be driven to rotate synchronously. Then, the quicklime powder will produce centrifugal force under the driven rotation of the distribution plate 29. The force continuously moves outward and is thrown out at a certain speed through the distribution holes on the distribution plate 29. Since the surface layer of the sludge after shaking and stratification is a light liquid with relatively good fluidity, the shaking sludge and the thrown quicklime will be quickly and evenly distributed during transportation. The quicklime will release heat violently when it meets water, instantly killing most pathogens in the sludge. At the same time, the strong alkaline environment generated by the reaction of quicklime and water strongly inhibits the activity of almost all microorganisms (including fermentation bacteria and pathogens), almost completely terminating the biological fermentation process in the sludge. The temperature sensor in the monitoring head 25 monitors the sludge surface temperature and adjusts the throwing of quicklime powder in real time.
[0048] The above benefits are as follows: this method can utilize the good fluidity of the light liquid on the surface of the sludge after stratification to disperse the quicklime quickly and evenly, so that the pathogens and microorganisms in the sludge are inactivated under the intense heat release and strong alkaline environment, and prevent the sludge from fermenting during transportation in the sealed sludge transfer box 2, thereby preventing the generation of toxic gases or substances and causing harm to the transporters and unloading personnel;
[0049] When the present invention is in use, the sewage treatment valve cover 6 on the top sealing seat 5 is opened, and then the sludge to be transported is transported to the sludge transfer box 2. During the sludge loading process, alternating current is applied to the magnetic vibration coil 15 in the vibration seat 13, so that the magnetic vibration ring where the magnetic vibration coil 15 is located has a constantly changing magnetic field, so that magnetic attraction and magnetic repulsion are continuously generated between the magnetic vibration coil 15 and the permanent magnet seat 14, causing the magnetic vibration coil 15 to slide at high frequency in the vibration seat 13 through the magnetic vibration ring. The continuous displacement change will drive the vibration membrane 16 to vibrate at high frequency. The vibration of the vibration membrane 16 will act on the loaded sludge, so that the sludge produces a certain stratification effect under the action of vibration, and the overall state is that the heavy liquid moves downward and the light liquid moves upward, thereby achieving preliminary treatment of the loaded sludge;
[0050] The upward movement of the light liquid will cause the sludge surface to have relatively good fluidity and floating ability, thereby causing the vibration expansion plate 26 to float on the sludge surface. In the subsequent transportation process, as the sludge transport vehicle seat 1 bumps and shakes during travel, the sludge in the sludge transfer box 2 will also shake along with it. Under the action of the sludge's own shaking, the sludge will further appear in layers. At the same time, during travel, the driving impeller 17 will rotate under the action of the airflow. The rotation of the driving impeller 17 will drive the vertical bevel gear 19 to rotate through the rotating shaft. The rotation of the vertical bevel gear 19 will drive the transverse bevel gear 20 to rotate, and then drive the two-way threaded shaft 21 to rotate. The moving seat 22 is fixed on the threaded groove on the two-way threaded shaft 21 through the fixing button 23. The inner sliding realizes the reciprocating movement of the moving seat 22 on the bidirectional threaded shaft 21. The movement of the moving seat 22 will drive the expansion plate 26 to move together. The movement of the expansion plate 26 will increase the shaking amplitude of the sludge surface liquid surface, so that the overall shaking of the sludge is amplified, which is convenient for strengthening the sludge stratification effect during driving. As the stratification proceeds, the position of the sludge bottom will quickly settle and compact, so that the sludge bottom tends to be stable in the subsequent process. The overall sludge is in a relative shaking state only on the surface, avoiding wear on the bottom of the sludge transfer box 2 during the continuous shaking of the sludge. The sludge surface liquid is light liquid, contains less sand and gravel, and has little pressure on the side wall of the sludge transfer box 2, which also reduces the shaking wear on the side wall of the sludge transfer box 2.
[0051] At the same time, the driving impeller 17 is subjected to a constant airflow direction during its rotation. Under this rotation direction, the bottom of the driving impeller 17 is in a negative pressure state. After the sludge is stratified to a certain extent, the bubbles in the sludge are basically discharged under the action of shaking. The control valve pipe on the fixed shaft seat 18 is opened to allow the gas in the sludge transfer box 2 to be discharged through the through hole on the fixed shaft seat 18. The sludge transfer box 2 will subsequently be in a relatively low pressure state. The control valve pipe on the fixed shaft seat 18 is then closed, and the air pressure sensor in the top sealing seat 5 will monitor the air pressure state in the sludge transfer box 2 in real time. Due to the gas flow rate and pressure outside the vehicle If the box leaks, the external high-pressure airflow will quickly enter the sludge transfer box 2, and the air pressure sensor will quickly detect it and issue an alarm, so that the transportation personnel can be informed in time and stop the vehicle for inspection. In this way, the magnetic vibration component can be used in conjunction with the vibration expansion plate 26 to vibrate and shake the sludge, so that the sludge is quickly separated into upper and lower layers during transportation, avoiding wear and tear on the bottom of the sludge during transportation. At the same time, the impeller 17 is driven to guide the gas in the sludge transfer box 2 to flow out, and the sludge transfer box 2 is maintained at a low pressure state. If the air pressure sensor detects a sudden increase in air pressure (intrusion of external high-pressure airflow), an alarm will be immediately issued to indicate that the seal has failed.
[0052] When the sludge is initially treated during transportation, after shaking to produce stratification, the control starts the drive motor 27 to drive the drive shaft to rotate. The rotation of the drive shaft will respectively drive the spiral conveying blades 28 and multiple distribution plates 29 to rotate. The rotation of the spiral conveying blades 28 will continuously transport the quicklime powder in the storage tank of the top sealing seat 5 downward, so that the quicklime powder is dispersed into each distribution plate 29. As the distribution plate 29 rotates in the sludge sterilization chamber 31, the falling quicklime powder will be driven to rotate synchronously. The quicklime powder will generate centrifugal force and move continuously outward under the driven rotation of the distribution plate 29, and will be thrown out at a certain speed through the distribution holes on the distribution plate 29. Since the surface layer of the sludge after shaking and stratification is light liquid with relatively good fluidity, it will be thrown out at a certain speed through the distribution holes on the distribution plate 29 as the transportation shakes. The moving sludge and the thrown quicklime will be quickly and evenly distributed. The quicklime will release heat violently when it meets water, instantly killing most pathogens in the sludge. At the same time, the strong alkaline environment generated by the reaction of quicklime and water strongly inhibits the activity of almost all microorganisms (including fermentation bacteria and pathogens), almost completely terminating the biological fermentation process in the sludge. The temperature sensor in the monitoring head 25 monitors the surface temperature of the sludge and adjusts the throwing of quicklime powder in real time. In this way, the quicklime can be dispersed quickly and evenly by taking advantage of the good fluidity of the surface light liquid after the sludge is layered, so that the pathogens and microorganisms in the sludge are inactivated in the violent heat release and strong alkaline environment, thereby preventing the sludge from fermenting during transportation in the sealed sludge transfer box 2 and producing toxic gases or substances, which may cause harm to the transportation and unloading personnel.
[0053] When unloading the sludge, the light liquid on the surface of the sludge is first extracted from the sewage treatment valve cover 6 through the external pump structure to achieve the separation of the liquid on the surface of the sludge. For the sedimentation part at the bottom of the sludge, the hydraulic lifting mechanism on the sludge transport seat 1 will lift the sludge transfer box 2, and then open the packaging door 4 through the hydraulic rotation mechanism 3. This existing conventional technology will not be described in detail here. At this time, the self-adjusting rack 9 is controlled to slide in the guide rail 8, so that multiple adjustment gear rings 10 are deflected under the action of the movement of the self-adjusting rack 9. The rotation of the adjustment gear ring 10 will drive the destruction plate 11 to rotate, squeezing the flat packaging film 12, so that the overall structure of the sludge deposited on the packaging film 12 is destroyed from the bottom, which is convenient for the staff to quickly unload the sludge deposited at the bottom. In this way, the shaking during transportation can be used to perform preliminary stratification treatment on the sludge, so that the sludge deposited at the bottom can be further dehydrated and compacted in the future, thereby achieving pretreatment of the sludge during transportation.
[0054] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
