Description

Technical Field

[0001] This invention relates to the field of sludge dewatering and purification technology, and in particular to a mobile sludge dewatering and purification device. Background Technology

[0002] Sludge dewatering and purification equipment is a sludge treatment method that removes water from fluid raw, concentrated or digested sludge and transforms it into semi-solid or solid sludge blocks. After dewatering, the sludge moisture content can be reduced to 55% to 80%, depending on the nature of the sludge and sediment and the efficiency of the dewatering equipment. Further dewatering of sludge is called sludge drying, and the moisture content of dried sludge is less than 10%.

[0003] In recent years, with the acceleration of urbanization and the improvement of residents' living standards, sewage treatment has gradually become an important factor affecting the environmental quality and living quality of towns and villages. Traditional sludge dewatering methods mainly include natural drying, mechanical dewatering and granulation. Natural drying and mechanical dewatering are suitable for sewage sludge, while granulation is suitable for sludge that has undergone coagulation and sedimentation.

[0004] However, in practical applications, sludge dewatering devices are bulky and have fixed installation locations, which severely limits their flexibility in application scenarios. Secondly, the lack of efficient simultaneous wastewater purification function in the sludge-water separation process leads to a reduction in overall treatment efficiency. In addition, the equipment relies on manual cleaning, which increases operation and maintenance costs and may affect the normal operation of the equipment due to untimely maintenance, thus leading to a decrease in work efficiency.

A dosing pipe is fixedly connected to the separation cylinder, and a sealing valve is fixedly connected to the dosing pipe.

[0016] Compared with the prior art, the present invention provides a mobile sludge dewatering and purification device, which has the following beneficial effects:

[0017] 1. This mobile sludge dewatering and purification device, through the setting of the airflow component, when the vacuum pump draws air into the separation cylinder, the negative pressure environment inside provides a power source for the material extraction pipe, realizing efficient extraction of sludge. At the same time, the airflow discharged from the airflow component drives the impeller and filter cartridge to rotate, which can effectively separate sludge and sewage.

[0018] 2. This mobile sludge dewatering and purification device, through the setting of linkage components, uses mechanical friction wheels to drive the friction wheels to rotate when the filter cylinder rotates, which can provide a power source for the stirring rod. The stirring rod rotates inside the separation cylinder, which can accelerate the mixing of the agent and the sewage, and further improve the sewage treatment efficiency.

[0019] 3. This mobile sludge dewatering and purification device, through the setting of the conveying components, the screw conveyor rod drives the scraper and conical frame to move simultaneously during the sludge conveying process. This can not only clean the inner wall of the filter cartridge and improve its separation quality, but also unclog the discharge pipe and improve the sludge discharge efficiency.

[0020] 4. This mobile sludge dewatering and purification device, through the setting of the discharge component, can filter and discharge the purified water, which can not only meet the spraying needs for road dust suppression, but also realize the scientific irrigation of surrounding vegetation, thus achieving the environmental protection goal of water resource recycling.

[0021] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention, through the arrangement of airflow components, creates a negative pressure environment when the vacuum pump draws gas from inside the separation cylinder. This negative pressure effect not only provides a power source for the extraction pipe to achieve efficient sludge extraction, but also allows the airflow discharged from the vacuum pump to drive the impeller to rotate the filter cylinder, achieving effective separation of sludge and wastewater. Secondly, the mechanical friction generated by the rotation of the filter cylinder causes the linkage component to transmit power to the stirring rod, achieving thorough mixing of wastewater and reagents, thereby significantly improving purification efficiency. In addition, when the conveying component transports and discharges sludge, the spiral conveying rod synchronously transmits power to the anti-clogging component, achieving automatic cleaning of the inner wall of the filter cylinder. This not only ensures the solid-liquid separation quality of the filter cylinder, but also optimizes the sludge discharge efficiency. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "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.

[0035] Example 1:

[0036] Reference Figures 1-4 and Figures 9-10 A mobile sludge dewatering and purification device includes a vehicle body 1 and a processing box 2 fixedly connected to the vehicle body 1. The processing box 2 has two cabinet doors for easy maintenance and repair of the internal equipment. A separation cylinder 3 is fixedly connected inside the processing box 2 to store the separated liquid. A filter cartridge 5 is installed inside the separation cylinder 3 through an airflow device. When the airflow device is working, the negative pressure inside the separation cylinder 3 is used to extract the sludge, and the gas discharged from the airflow device drives the filter cartridge 5 to rotate along the axis of the separation cylinder 3, thereby achieving sludge-water separation. A stirring rod 6 is installed inside the separation cylinder 3 and has a linkage component that works with the filter cartridge 5. When the filter cartridge 5 rotates, the linkage component controls the rotation of the stirring rod 6. The water flow inside the separation cylinder 3 is stirred. During the stirring process, the staff put the water purification agent into the separation cylinder 3 and uses the stirring rod 6 to fully stir the sewage and the agent to make them mix and react quickly. The discharge pipe 8 installed at the discharge port of the filter cylinder 5 is rotated. The end of the discharge pipe 8 away from the filter cylinder 5 is fixedly connected to the discharge valve 9. The bottom of the discharge valve 9 is equipped with a conveying component. After the sludge and sewage are separated, the discharge valve 9 is opened to make the sludge inside the filter cylinder 5 discharge into the conveying component. The anti-clogging component is set in the discharge pipe 8 and cooperates with the conveying component. When the conveying component transports the separated sludge, the anti-clogging component is used to unclog the discharge pipe 8 and clean the inner wall of the filter cylinder 5, reducing the frequency of manual maintenance and improving the sludge treatment efficiency.

[0037] Specifically, through the arrangement of the airflow components, the vacuum pump 4 creates a negative pressure environment when drawing gas from inside the separation cylinder 3. This negative pressure effect not only provides a power source for the extraction pipe 42 to achieve efficient sludge extraction, but also the airflow discharged by the vacuum pump 4 can drive the impeller 44 to rotate the filter cylinder 5, achieving effective separation of sludge and wastewater. Secondly, the mechanical friction generated by the rotation of the filter cylinder 5 causes the linkage component to transmit to the stirring rod 6, achieving full mixing of wastewater and reagents, thereby significantly improving purification efficiency. In addition, when the conveying component transports and discharges sludge, the spiral conveying rod 1002 synchronously transmits power to the anti-clogging component, achieving automatic cleaning of the inner wall of the filter cylinder 5, which not only ensures the solid-liquid separation quality of the filter cylinder 5, but also optimizes the sludge discharge efficiency.

[0038] Example 2:

[0039] Reference Figures 1-5 and Figures 9-10 The implementation is basically the same as in Example 1, but preferably, it is a specific implementation plan for sludge extraction and separation and wastewater mixing and purification.

[0040] The airflow components include a vacuum pump 4 fixedly mounted on the vehicle body 1, with a pipe fixedly connected to the air inlet of the vacuum pump 4, and the end of the pipe away from the vacuum pump 4 fixedly connected to the inner cavity of the separation cylinder 3; and an air guide shroud 41 fixedly mounted on the processing box 2, with the inner cavity of the air guide shroud 41 fixedly connected to the pipe at the air outlet of the vacuum pump 4, and a material extraction pipe 42 fixedly connected to the air guide shroud 41. When the vacuum pump 4 starts and performs air extraction operation inside the separation cylinder 3, a negative pressure environment will be rapidly formed inside its cavity. This pressure difference serves as the driving force, flowing through the material extraction pipe 42. A siphon effect is generated to achieve efficient sludge extraction; the feed pipe 43, which is rotatably connected inside the air guide shroud 41, is connected to the inner cavity of the extraction pipe 42, and the end of the feed pipe 43 away from the air guide shroud 41 is fixedly connected to the filter cartridge 5; the impeller 44 is fixedly sleeved on the feed pipe 43 and is located at the outlet of the vacuum pump 4. When the gas discharged from the vacuum pump 4 blows towards the impeller 44, the rotation of the impeller 44 can drive the filter cartridge 5 to rotate. By utilizing the rotation of the filter cartridge 5, the effective separation of sludge and sewage can be achieved.

[0041] It also includes a fan 45 fixedly installed on the vehicle body 1. The air outlet end of the fan 45 is fixedly connected to an air outlet pipe 46. The end of the air outlet pipe 46 away from the fan 45 is fixedly connected to the pipe at the air outlet end of the vacuum pump 4.

[0042] The linkage includes a sealing shell 7 fixedly installed inside the separation cylinder 3, a stirring rod 6 rotatably connected to the sealing shell 7, a transmission rod 71 rotatably connected to the sealing shell 7, a first synchronous wheel 72 fixedly sleeved on the transmission rod 71, and a second synchronous wheel 73 fixedly connected to the stirring rod 6 via a synchronous belt; a friction wheel 74 fixedly connected to the end of the transmission rod 71 away from the sealing shell 7, and a friction pad 75 fixedly sleeved on the filter cylinder 5 that abuts against the friction wheel 74. When the filter cylinder 5 drives the friction pad 75 to rotate, the friction between the friction pad 75 and the friction wheel 74 can cause the stirring rod 6 to rotate, thereby stirring the sewage inside the separation cylinder 3.

[0043] Specifically, during sludge extraction, the staff uses an external control switch to start the vacuum pump 4. The vacuum pump 4 evacuates the air inside the separation cylinder 3, quickly creating a negative pressure environment inside the cylinder. This pressure difference serves as the main driving force, causing the extraction pipe 42 to generate a siphon effect, extracting the sludge and transporting it into the filter cartridge 5. At the same time, the gas discharged by the vacuum pump 4 is introduced into the air guide hood 41. With the synergistic effect of the blower 45, the airflow speed inside the air guide hood 41 is significantly increased. The high-speed airflow drives the impeller 44 to rotate, which in turn drives the feed pipe 43 and the filter cartridge 5 to rotate synchronously. The centrifugal force generated by the rotation of the filter cartridge 5 allows the sewage to be effectively discharged through the gaps in the filter cartridge 5, achieving mechanical separation of sludge and sewage.

[0044] During the rotation of the filter cartridge 5, wastewater separation is achieved. The friction pad 75 on its surface rotates with the filter cartridge 5 and generates friction transmission with the friction wheel 74. This friction drives the friction wheel 74 to rotate, and then transmits the power to the first synchronous wheel 72 through the transmission rod 71. The first synchronous wheel 72 transmits the motion to the second synchronous wheel 73 through the synchronous belt, and finally drives the stirring rod 6 to rotate. This linkage design realizes the continuous stirring of wastewater in the separation cartridge 3. When the staff adds the agent to the separation cartridge 3, the stirring effect can significantly improve the mixing efficiency of the agent and wastewater, thereby optimizing the wastewater treatment effect.

[0045] Example 3:

[0046] Reference Figures 1-4 , Figures 6-8 and Figure 10 The implementation is basically the same as in Example 1, but preferably, it is a specific implementation plan for conveying sludge inside the filter cartridge 5 and cleaning the inner wall of the filter cartridge 5.

[0047] The conveying components include a conveying shell 10 fixedly connected to the separation cylinder 3, one end of the conveying shell 10 penetrating into the inner cavity of the separation cylinder 3, the inlet of the conveying shell 10 communicating with the inner cavity of the discharge valve 9, a motor 1001 fixedly mounted on the conveying shell 10, and a spiral conveying rod 1002 rotatably connected to the output end of the motor 1001; and a sludge tank 1003 fixedly mounted on the processing tank 2, with the inner cavity of the sludge tank 1003 fixedly connected to the discharge port of the conveying shell 10.

[0048] The anti-clogging component includes a bracket 11 fixedly connected inside the discharge pipe 8. A reciprocating screw 1101 is rotatably connected to the bracket 11 via a bearing. The end of the reciprocating screw 1101 away from the bracket 11 is rotatably connected to the bottom of the feed pipe 43. A reciprocating sleeve 1102 is slidably sleeved on the reciprocating screw 1101. A conical frame 1103 is fixedly sleeved on the reciprocating sleeve 1102. The conical frame 1103 is located at the upper end of the discharge pipe 8. When the reciprocating screw 1101 rotates, the reciprocating sleeve 1102 drives the conical frame 1103 to move vertically reciprocally, which can prevent the discharge pipe from clogging. The sludge blockage inside the feed pipe 8 is cleared. A T-shaped rod 1104, which is slidably connected to the support 11, is fixedly connected to the conical frame 1103 and used to vertically limit the conical frame 1103. A scraper 1105 is fixedly sleeved on the reciprocating screw 1101. The side of the scraper 1105 away from the reciprocating screw 1101 abuts against the inner wall of the filter cylinder 5. When the reciprocating screw 1101 rotates, the scraper 1105 rotates along the inside of the filter cylinder 5, which can clean the sludge adhering to its inner wall. On the one hand, it improves the dewatering quality of the filtered sludge, and on the other hand, it accelerates the sludge discharge efficiency.

[0049] It also includes a first bevel gear 1106 fixedly sleeved on the reciprocating lead screw 1101, a second bevel gear 1107 meshing with the first bevel gear 1106, a positioning rod 1108 rotatably connected to the side of the second bevel gear 1107 away from the first bevel gear 1106, a support rod rotatably connected to the positioning rod 1108 via a bearing, and the bottom of the support rod being fixedly connected to the top of the conveying shell 10; a first spur gear 1109 fixedly connected to the end of the positioning rod 1108 away from the first bevel gear 1106, and a second spur gear 1110 meshing with the first spur gear 1109 and fixedly connected to the screw conveyor 1002.

[0050] Specifically, after the sludge and wastewater separation process is completed, the staff turns off the vacuum pump 4 and starts the motor 1001 and the discharge valve 9 in sequence through the external control system. When the discharge valve 9 is opened, the sludge separated in the filter cartridge 5 enters the conveying shell 10 through the discharge pipe 8 under the action of gravity. At the same time, the motor 1001 drives the screw conveyor 1002 to rotate, so as to realize the continuous conveying and discharge of sludge.

[0051] During the sludge conveying process, the rotation of the screw conveyor 1002 drives the second spur gear 1110 to rotate. The rotation of the second spur gear 1110 drives the first spur gear 1109 to rotate. The rotation of the first spur gear 1109 drives the positioning rod 1108 to rotate. The rotation of the positioning rod 1108 drives the second bevel gear 1107 to rotate. The rotation of the second bevel gear 1107 drives the first bevel gear 1106 to rotate. The rotation of the first bevel gear 1106 drives the reciprocating screw 1101 to rotate. The reciprocating screw 1101... When rotating, the scraper 1105 rotates inside the filter cylinder 5. The scraper 1105 cleans the inside of the filter cylinder 5, removing the sludge adhering to the inner wall of the filter cylinder 5. This improves both the sludge discharge efficiency and the separation quality of the filter cylinder 5. Furthermore, during the rotation of the reciprocating screw 1101, the reciprocating sleeve 1102 drives the conical frame 1103 to move vertically back and forth. When the conical frame 1103 moves vertically back and forth, it can squeeze the sludge at the bottom of the inner cavity of the filter cylinder 5 to the discharge pipe 8. This improves the sludge discharge efficiency and prevents the sludge from clogging the discharge pipe 8.

[0052] Example 4:

[0053] Reference Figure 2 and Figure 10 The implementation is basically the same as in Example 1, but preferably, it is a specific implementation plan for the filtration and discharge of water purified inside the separator 3.

[0054] The treatment box 2 is equipped with a discharge device that is connected to the separation cylinder 3. The discharge device is used to filter and discharge the water inside the separation cylinder 3. After the water inside the separation cylinder 3 is purified, the water is extracted using the discharge device, which can be used for irrigation of vegetation or dust suppression on the road surface.

[0055] The discharge components include a water pump 12 fixedly installed inside the treatment tank 2, with the inlet end of the water pump 12 fixedly connected to a water collection shell 1201 via a pipe, and a filter element 1202 fixedly installed inside the water collection shell 1201; an inlet pipe 1203 fixedly connected to the end of the water collection shell 1201 away from the water pump 12, and the end of the inlet pipe 1203 away from the water collection shell 1201 connected to the inner cavity of the separation cylinder 3; an outlet pipe 1204 fixedly connected to the outlet end of the water pump 12, with a liquid outlet valve 1205 fixedly sleeved on the outlet pipe 1204 for controlling the water flow during discharge; and a dosing pipe 1206 fixedly connected to the separation cylinder 3, with a sealing valve fixedly connected to the dosing pipe 1206 for sealing the separation cylinder 3.

[0056] Specifically, after the sewage purification treatment is completed, the staff starts the water pump 12 through the external control system. The water pump 12 transports the treated sewage in the separation cylinder 3 to the water collection shell 1201. The water is then deeply filtered through the built-in filter element 1202 to further remove residual impurities. The purified water flow is precisely controlled by the discharge valve 1205 to regulate the discharge rate. This can meet the spraying needs for road dust suppression and also achieve scientific irrigation of surrounding vegetation, thus achieving the environmental protection goal of water resource recycling.

[0057] Example 5:

[0058] Similar to Example 1, a mobile sludge dewatering and purification method is proposed based on Example 1, with the following operation steps:

[0059] Step 1: Operate vehicle 1 to precisely transport the sludge dewatering and purification device to the designated work area;

[0060] Step 2: Start the airflow device to evacuate the separator 3 to establish a negative pressure working environment. Use the pressure difference to efficiently extract sludge. At the same time, use the airflow device to discharge gas to drive the filter cartridge 5 to rotate, so as to achieve the initial separation of sludge and sewage.

[0061] Step 3: The mechanical energy generated by the rotation of the filter cylinder 5 drives the linkage to rotate synchronously, which in turn drives the stirring rod 6 to rotate, adding the reagent into the separation cylinder 3, and using the rotation of the stirring rod 6 to fully and evenly mix the reagent with the sewage.

[0062] Step 4: After the sludge and sewage are separated, open the discharge valve 9 to allow the sludge inside the filter cartridge 5 to be discharged through the conveyor.

[0063] Step 5: During the sludge conveying process, the internal spiral conveying rod 1002 drives the scraper 1105 in the anti-clogging component to rotate along the inside of the filter cylinder 5, achieving efficient cleaning of the inner wall of the filter cylinder 5. At the same time, the conical frame 1103 moves vertically back and forth, which can push the sludge to the discharge pipe 8, thereby improving the sludge discharge efficiency and preventing the sludge from clogging the discharge pipe 8.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
