Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to a bifurcated bottom-turning chlor-alkali salt sludge treatment device and its treatment method. Background Technology

[0002] In chlor-alkali industrial production, the treatment of salt mud has always been a crucial step. Traditional chlor-alkali salt mud treatment methods often suffer from numerous problems. During the dewatering process, due to the lack of effective pretreatment and a reasonable extrusion process design, the distribution of salt mud is often uneven. This results in the pressure not being applied evenly to different parts of the salt mud during subsequent extrusion dewatering operations, leading to situations where the pressure is either too high or too low in certain areas.

[0003] When the local pressure is too high, the salt mud may be over-compressed, which can damage its structure and cause some water to be compacted and difficult to drain. This also increases equipment wear and energy consumption. Conversely, if the local pressure is too low, the water cannot be effectively squeezed out, resulting in poor dehydration of the salt mud and excessively high water content in some areas, which affects the overall quality stability of the salt mud.

[0004] Furthermore, due to its unique location, the central part of the salt mud has a relatively long water drainage path, making it difficult to achieve sufficient dewatering using traditional methods. This results in a high water content in this portion of the salt mud, severely impacting the overall dewatering quality and hindering subsequent recycling or further processing. These problems urgently require a new salt mud treatment technology to improve the uniformity, efficiency, and quality of salt mud dewatering, meeting the needs of industrial production and environmental protection requirements. Summary of the Invention

[0005] This invention proposes a bifurcated bottom-turning chlor-alkali salt mud treatment equipment and method, which solves the problem of poor uniformity in the dewatering of chlor-alkali salt mud in related technologies.

After the swing lifting member rises, the fourth gear moves away from the first gear and the second gear.

[0009] As a further technical solution, the pressure plate has a groove, and the extrusion member includes: An extrusion cylinder is mounted on the frame and has an extrusion chamber. Both the first gear and the second gear are rotatably mounted on the extrusion cylinder. The pupil valve, comprising two pupil valves, is located at the upper and lower ends of the compression chamber respectively. Each pupil valve has an opening and closing valve plate arranged in a plurality of circumferential circles. A rotating roller, comprising several rotating rollers, with its two ends respectively disposed on the opening and closing valve plates of the two pupil valves, and the rotating rollers slidably disposed within the slide groove.

[0010] As a further technical solution, the extruder is rotatably mounted on the frame, the lifting member is raised and lowered relative to the frame, and the rotating roller is configured to abut against the auxiliary bag.

[0011] As a further technical solution, the extrusion cylinder has a mud outlet located on the end of the extrusion cylinder near the fixed member, the forked roller has an abutment end, and the forked bottom-turning chlor-alkali sludge treatment equipment further includes: A vibrating element is mounted on the frame, and the forked roller is configured such that when it rises to its highest point, the output end of the vibrating element abuts against the abutting end.

The second elastic element has one end acting on the extrusion cylinder and the other end acting on the second ratchet, providing the second pawl with the force to engage the second ratchet.

[0014] As a further technical solution, the extrusion cylinder also has a water outlet, which is located on one side of the mud outlet.

[0015] A bifurcation-type bottom-turning chlor-alkali salt sludge treatment method, using bifurcation-type bottom-turning chlor-alkali salt sludge treatment equipment.

[0016] The working principle and beneficial effects of this invention are as follows: In this invention, compared to existing chlor-alkali sludge treatment methods, the extrusion rollers first perform preliminary extrusion on the sludge in the filter bag, removing a large amount of free water. Then, the bifurcated rollers tumble the sludge and push it into the auxiliary bag. When the bifurcated rollers push the filter bag into the auxiliary bag, the pre-dehydrated chlor-alkali sludge can be evenly distributed between the filter bag and the auxiliary bag. When the subsequent extrusion components extrude the auxiliary bag, the pressure can be more evenly distributed to all parts of the sludge. Compared to unevenly distributed sludge, there is no problem of excessive or insufficient local pressure, allowing the water in the sludge to be squeezed out more evenly. This helps improve the overall uniformity of dehydration, ensuring that the entire sludge body reaches a similar degree of dehydration, avoiding the problem of unstable sludge quality caused by local dehydration differences, such as some areas having excessively high or low moisture content.

[0017] Uniformly distributed salt mud adapts better to pressure changes during extrusion, allowing water to drain more easily from its interior. Under uniform pressure, the gaps between salt mud particles more effectively form drainage channels, promoting rapid water flow and drainage. Compared to the potential for water blockage or retention in unevenly distributed mud, this uniform distribution accelerates dehydration and improves dehydration efficiency.

[0018] The tumbling action of the bifurcated rollers exposes the less dehydrated central portion of the salt mud to the outside, allowing it to undergo repeated pressing. During the further pressing process of the auxiliary bag and the extruder, these previously difficult-to-handle areas receive more thorough dehydration, thereby improving overall dehydration efficiency and shortening the time required to reach the ideal degree of dehydration.

[0019] Due to its unique location, the central part of the salt mud is difficult to drain. By using a forked roller to tumble and push the mud, along with auxiliary bags and extruders to focus pressure on this section, the moisture in the central part is effectively removed. Repeated extrusion ensures effective dewatering of the central salt mud, reducing its moisture content and improving dewatering quality. This results in a more ideal state for the salt mud, facilitating subsequent recycling or further processing. Attached Figure Description

[0026] Reference Figures 1-8 This is the first embodiment of the present invention, which proposes a bifurcated bottom-turning chlor-alkali sludge treatment device for dewatering chlor-alkali sludge in cylindrical filter bags. The device includes a frame 1, a fixing member 2 mounted on the frame 1, the fixing member 2 having a first fixing hole 201 and a second fixing hole 203, the first fixing hole 201 and the second fixing hole 203 being coaxially arranged and located on opposite sides of the fixing member 2. The first fixing hole 201 is used to fix the filter bag. A lifting member 3 is lifted relative to the fixing member 2 and located on one side of the second fixing hole 203. An auxiliary bag 4 is mounted on the lifting member 3, the diameter of the auxiliary bag 4 being larger than the diameter of the filter bag. A pressing roller 5 is lifted on the frame 1 and configured to press the filter bag during lifting. A pressing member 6 is mounted on the frame 1 and has a pressing chamber 601, where both the auxiliary bag 4 and the lifting member 3 are located. The pressing member 6 is used to press the auxiliary bag 4. A bifurcated roller 7 is lifted on the frame 1, and after the bifurcated roller 7 rises, it pushes the filter bag into the auxiliary bag 4.

[0027] In this embodiment, the frame 1 provides stable support for the entire equipment, ensuring accurate installation and stable operation of all components, and withstanding various forces and loads generated during equipment operation. The fixing component 2 securely fixes the filter bag containing chlor-alkali sludge to the equipment through the first fixing hole 201, preventing displacement of the filter bag during processing and ensuring the accuracy and stability of the processing. The lifting component 3 can move the auxiliary bag 4 up and down, preventing the filter bag from failing to remove sludge after dewatering. It should be noted that the lifting component 3 has a ring structure with several clearance holes to avoid interference with other structures. The auxiliary bag 4 has a larger diameter than the filter bag, providing more space for the initially dewatered sludge, facilitating further compression dewatering. The compression roller 5 applies pressure to the sludge in the filter bag through its lifting action, squeezing out the water and achieving initial dewatering, laying the foundation for more thorough dewatering later. The compression component 6 can squeeze the auxiliary bag 4 containing sludge, providing stronger pressure to further remove water from the sludge and improve the dewatering effect. When the bifurcated roller 7 rises, it flips the salt mud in the filter bag, so that the part in the middle that is not easy to dehydrate can be exposed to the outside to be repeatedly squeezed. At the same time, after the initial dehydration is completed, the filter bag is turned over and the initially dehydrated salt mud is pushed into the auxiliary bag 4, which promotes the efficient operation of the processing process.

[0028] Compared to existing chlor-alkali sludge treatment technologies, the extrusion roller 5 first performs preliminary extrusion on the sludge in the filter bag, removing a large amount of free water. Next, the bifurcated roller 7 flips the sludge and pushes it into the auxiliary bag 4. When the bifurcated roller 7 pushes the filter bag into the auxiliary bag 4, the pre-dehydrated chlor-alkali sludge can be evenly distributed between the filter bag and the auxiliary bag 4. When the subsequent extrusion component 6 extrudes the auxiliary bag 4, the pressure can be more evenly distributed to all parts of the sludge. Compared to unevenly distributed sludge, there is no problem of excessive or insufficient local pressure, allowing the water in the sludge to be squeezed out more evenly. This helps improve the overall uniformity of dewatering, ensuring that the entire sludge body reaches a similar degree of dewatering, avoiding instability in sludge quality caused by local dewatering differences, such as excessively high or low moisture content in some areas.

[0029] Uniformly distributed salt mud adapts better to pressure changes during extrusion, allowing water to drain more easily from its interior. Under uniform pressure, the gaps between salt mud particles more effectively form drainage channels, promoting rapid water flow and drainage. Compared to the potential for water blockage or retention in unevenly distributed mud, this uniform distribution accelerates dehydration and improves dehydration efficiency.

[0030] The flipping action of the forked roller 7 exposes the less dehydrated central portion of the salt mud to the outside, allowing it to undergo repeated pressing. During the further pressing process of the auxiliary bag 4 and the extruder 6, these previously difficult-to-handle areas can be more thoroughly dehydrated, thereby improving the overall dehydration efficiency and shortening the time required to reach the ideal dehydration level.

[0031] Due to its unique location, the central part of the salt mud is difficult to drain. Through the tumbling and pushing action of the forked roller 7, and the focused squeezing of this portion of the salt mud by the auxiliary bag 4 and the extruder 6, the moisture in the central part is effectively removed. Repeated squeezing ensures effective dewatering of the central salt mud, reduces the moisture content of the dewatered mud, improves the dewatering quality, and brings the salt mud to a more ideal state, which is beneficial for subsequent recycling or further processing.

[0032] Furthermore, it also includes a pressure plate 8, which is slidably disposed in the extrusion chamber 601. The pressure plate 8 is located on the side of the lifting member 3 away from the second fixed hole 203. The pressure plate 8 has a through hole 801. After the pressure plate 8 is raised or lowered, the auxiliary bag 4 passes through or cancels the through hole 801. The diameter of the through hole 801 is larger than the diameter of the fork roller 7.

[0033] In this embodiment, after the auxiliary bag 4 passes through the through hole 801 of the pressure plate 8, the through hole 801 of the pressure plate 8 can apply additional pressure to the salt mud inside the auxiliary bag 4. Before the extruder 6 squeezes the auxiliary bag 4, the pressure plate 8 restricts the expansion of the auxiliary bag 4 from all sides, so that the salt mud inside the auxiliary bag 4 is pre-compressed, and the chlor-alkali salt mud is shaped through the through hole, further improving the dewatering effect of the extruder 6 during extrusion. This dual extrusion action can more effectively remove water from the salt mud, especially for those bound water or water that is difficult to drain after preliminary dewatering. With the auxiliary shaping of the pressure plate 8, the water can be more thoroughly separated from the salt mud during extrusion by the extruder 6, reducing the water content of the salt mud and improving the dewatering quality.

[0034] The sliding arrangement of the pressure plate 8 can adjust the distribution and shape of the salt mud during the lifting and lowering of the auxiliary bag 4. When the forked roller 7 rises, the salt mud in the extrusion chamber 601 is more evenly distributed within the auxiliary bag 4 due to the combined action of the auxiliary bag 4 and the pressure plate 8, preventing local accumulation or uneven blockage. Simultaneously, the diameter of the through hole 801 in the pressure plate 8 is slightly larger than the diameter of the forked roller 7. This design can limit excessive flow of the salt mud to a certain extent, keeping it within a suitable range, which is beneficial for subsequent extrusion and dewatering operations, ensuring that the salt mud remains in a dewatering-friendly state throughout the entire processing.

[0035] Furthermore, it also includes a first screw 9, which is rotatably mounted on the extruder 6. A lifting member 3 has a first threaded hole and is threadedly connected to the first threaded hole. The first screw 9 has a first gear portion 901. A second screw 10 is rotatably mounted on the extruder 6. A pressure plate 8 has a second threaded hole, and the second screw 10 is threadedly connected to the second threaded hole. The second screw 10 has a second gear portion 1001. A swing lifting member 11 swings and lifts on the frame 1. A first gear 12 is rotatably mounted on the extruder 6. The first gear 12 is an inner ring gear. The first gear 12 and... The first gear 901 is engaged, and the second gear 13 is rotatably mounted on the extrusion member 6. The second gear 13 is a double-sided toothed ring and has a third tooth 1301. The third tooth 1301 is engaged with the second gear 1001. The third gear 14 is rotatably mounted at one end of the swing lifting member 11. The fourth gear 15 is engaged with the third gear 14. After the swing lifting member 11 swings, the fourth gear 15 is engaged with the first gear 12 or the second gear 13. After the swing lifting member 11 rises, the fourth gear 15 moves away from the first gear 12 and the second gear 13.

[0036] In this embodiment, the threaded connection between the first screw 9 and the lifting component 3, and the threaded connection between the second screw 10 and the pressure plate 8, enables precise control of the lifting movement of the lifting component 3 and the pressure plate 8. By rotating the first screw 9 and the second screw 10, the height position of the lifting component 3 and the pressure plate 8 can be precisely adjusted according to different stages and requirements of salt mud treatment. This precise control helps optimize the distribution and extrusion process of salt mud within the equipment, ensuring that the salt mud is in its optimal state at different treatment steps. For example, after the initial dewatering of the salt mud, the lifting component 3 is precisely controlled to install the auxiliary bag 4 to one side of the second fixing hole 203, allowing the filter bag to enter the auxiliary bag 4 for more effective secondary extrusion dewatering. The design of the first gear 12 and the second gear 13 increases the stability and accuracy of the gear transmission. The first gear 12 and the third gear 1301 mesh with the first gear 901 of the first screw 9 and the second gear 1001 of the second screw 10, respectively, making the force transmission during rotation smoother, reducing the impact of gear clearance and wobbling on lifting control, further improving the accuracy of lifting motion, ensuring that the equipment can operate according to the predetermined parameters during operation, and improving the quality and consistency of dehydration treatment.

[0037] The combined design of the swing lifting component 11, the third gear 14, the fourth gear 15, the first gear 12, and the second gear 13 achieves efficient power transmission and coordinated operation between components. The swinging and lifting movements of the swing lifting component 11 can flexibly transmit power to the first gear 12 or the second gear 13 through the third gear 14 and the fourth gear 15, thereby driving the first screw 9 or the second screw 10 to rotate. This design allows one power source to control the movement of multiple components, simplifying the power system of the equipment and improving the overall efficiency of the equipment. During the salt mud treatment process, each component can work sequentially or simultaneously as needed. For example, when it is necessary to squeeze the auxiliary bag 4, the swing lifting component 11 swings to engage the fourth gear 15 with the first gear 12, driving the first screw 9 to rotate, realizing the lifting of the lifting component 3, thereby controlling the position and degree of squeezing of the auxiliary bag 4; when it is necessary to adjust the position of the pressure plate 8, the swing lifting component 11 swings in the opposite direction to engage the fourth gear 15 with the third tooth 1301, driving the second screw 10 to rotate, precisely adjusting the height of the pressure plate 8. The coordinated operation of all components ensures that the equipment can operate efficiently at different processing stages, improving the automation level and processing capacity of the equipment.

[0038] Furthermore, the pressure plate 8 has a sliding groove 802, and the extrusion component 6 includes an extrusion cylinder 602, which is mounted on the frame 1. The extrusion cylinder 602 has an extrusion chamber 601. The first gear 12 and the second gear 13 are both rotatably mounted on the extrusion cylinder 602. There are two pupil valves 603, which are located at the upper and lower ends of the extrusion chamber 601, respectively. The pupil valve 603 has an opening and closing valve plate 604, which is arranged in several circles. There are several rotating rollers 605, and the two ends of the rotating rollers 605 are respectively mounted on the opening and closing valve plates 604 of the two pupil valves 603. The rotating rollers 605 are slidably mounted in the sliding groove 802.

[0039] In this embodiment, the extrusion cylinder 602 provides a stable extrusion space, and its internal extrusion chamber 601 can accommodate the auxiliary bag 4 and the salt mud, providing a basic environment for the extrusion operation. The first gear 12 and the second gear 13 are rotatably mounted on the extrusion cylinder 602, facilitating coordinated work with other components to achieve precise control of the extrusion process. The design of the pupil valve 603 brings flexibility to the extrusion process. The two pupil valves 603 are located at the upper and lower ends of the extrusion chamber 601, respectively, and their opening and closing valve plates 604 can be opened and closed as needed. During the extrusion of the salt mud, the opening and closing valve plates 604 are closed, and the rotating roller 605 abuts against and extrudes the auxiliary bag 4. The two ends of several rotating rollers 605 are respectively mounted on the opening and closing valve plates 604 of the two pupil valves 603, and can slide within the chute 802. During the extrusion process, the rotating rollers 605 can automatically adjust their position according to the shape and pressure changes of the salt mud, so that the salt mud is subjected to more uniform extrusion. Meanwhile, the rolling action of the rotating roller 605 can reduce the friction between the salt mud and the inner wall of the extrusion chamber 601, prevent the salt mud from sticking or clogging during the extrusion process, and ensure the smooth progress of the extrusion process.

[0040] The combined design of the extrusion cylinder 602, pupil valve 603, and rotating roller 605 improves the stability and reliability of the equipment. The extrusion cylinder 602, as the main load-bearing component, provides stable support for the entire extrusion process. The opening and closing valve plate 604 of the pupil valve 603 has a robust structure capable of withstanding high pressure, ensuring that it will not deform or be damaged during extrusion. The two ends of the rotating roller 605 are positioned on the opening and closing valve plate 604, increasing the stability of the entire structure and preventing the rotating roller 605 from shifting or falling off during extrusion. This stable structural design allows the equipment to maintain good performance during long-term operation, reducing the incidence of equipment failure and improving the reliability and service life of the equipment.

[0041] Furthermore, the extruder 6 is rotatably mounted on the frame 1, the lifting member 3 is raised and lowered relative to the frame 1, and the rotating roller 605 is configured to abut against the auxiliary bag 4.

[0042] In this embodiment, when the extruder 6 rotates, the rotating roller 605 rotates synchronously and abuts against the auxiliary bag 4. This design enables omnidirectional and uniform extrusion of the salt mud inside the auxiliary bag 4. As the extruder 6 rotates, the rotating roller 605 applies pressure to the salt mud at different positions, avoiding the problems of excessive or uneven local pressure that may occur with traditional fixed extrusion methods. Each rotating roller 605 continuously acts on the salt mud at different angles, allowing the water in the salt mud to be squeezed out more evenly, thereby improving dewatering efficiency and quality. The continuous rotation and extrusion of the rotating roller 605 can also repeatedly knead the salt mud, further breaking down its structure and making it easier to release the water. This kneading-like effect helps improve the dewatering effect of the salt mud, especially for salt mud with high viscosity or dense structure, effectively breaking the internal water binding force and improving dewatering efficiency.

[0043] The synchronous rotation design of the extruder 6 and the rotating roller 605 increases the stability of equipment operation. During the extrusion process, the contact between the rotating roller 605 and the auxiliary bag 4 provides stable support, preventing excessive deformation or displacement of the auxiliary bag 4 during extrusion. At the same time, the uniform distribution and synchronous rotation of the rotating roller 605 make the entire extrusion process smoother, reducing the risk of equipment vibration and damage caused by uneven local pressure or sudden force.

[0044] Furthermore, the extrusion cylinder 602 has a mud outlet 606, which is located on the end side of the extrusion cylinder 602 near the fixed member 2. The forked roller 7 has an abutment end 701 and also includes a vibrating member 16, which is mounted on the frame 1. When the forked roller 7 is raised to its highest point, the output end of the vibrating member 16 abuts against the abutment end 701. The screw conveyor 17 is mounted at the mud outlet 606.

[0045] In this embodiment, the lifting component 3 rises, causing the auxiliary bag 4 to rise as well. Simultaneously, the filter bag is inverted and secured inside the extrusion chamber 601 under the continuous action of the bifurcated roller 7. At this time, the vibrating component 16 starts, its output end contacting the contact end 701 of the bifurcated roller 7, generating vibration that is transmitted to the equipment, loosening the salt mud. The screw conveyor 17 starts, located at the mud outlet 606 of the extrusion cylinder 602, transporting the dewatered salt mud to the designated location. During the mud discharge process, the vibrating component 16 continues to operate, assisting in the smooth discharge of the salt mud, ensuring a smooth and thorough discharge process, and reducing salt mud residue.

[0046] When sludge discharge is required, the lifting component 3 rises, causing the auxiliary bag 4 to rise as well. Under the continuous action of the forked roller 7, the filter bag is turned inside out and placed inside the extrusion chamber 601. This coordinated action creates a structural change that facilitates sludge discharge. The turned-out filter bag exposes the salt sludge to the outside, which helps with sludge discharge. At the same time, the rising of the auxiliary bag 4 scrapes against the salt sludge, making it easier for the salt sludge to fall off.

[0047] The coordinated action of components such as the lifting element 3 and the forked roller 7 makes the sludge removal process more orderly and efficient. Compared with traditional sludge removal methods, this design can significantly shorten the sludge removal time. In traditional methods, salt sludge is difficult to remove due to accumulation and adhesion inside the filter bags, requiring a long cleaning time. However, this equipment, through operations such as filter bag reversal, allows the salt sludge to fall off quickly, reducing obstacles in the sludge removal process and thus increasing the sludge removal speed. The filter bag reversal operation can effectively reduce the residue of salt sludge inside the equipment. During the sludge removal process, the salt sludge can be removed from the equipment more thoroughly, avoiding accumulation and blockage inside the equipment. Different chlor-alkali salt sludge may have different characteristics such as moisture content, viscosity, and particle size. The sludge removal design of this equipment, through the coordinated action of filter bag reversal, auxiliary bag 4 lifting, and vibrating element 16 and screw conveyor 17, can adapt to the sludge removal needs of salt sludge with different characteristics. For salt mud with high moisture content and strong viscosity, the vibrating component 16 can better loosen the salt mud, and the rising of the auxiliary bag 4 and the inverting of the filter bag can provide greater squeezing force, making it easier for the salt mud to be discharged. For salt mud with larger particles, the screw conveyor 17 can be adjusted according to the particle size to ensure smooth conveying. This adaptability allows the equipment to maintain good mud discharge effect when processing various types of salt mud, improving the versatility and practicality of the equipment.

[0048] Furthermore, the extrusion cylinder 602 has an air chamber 609, the air chamber 609 has a high pressure outlet 610, the high pressure outlet 610 is arranged in a plurality of arrangements on the inner wall of the extrusion chamber 601, and also includes a pusher 18 disposed at the end of the extrusion cylinder 602 away from the fixing member 2, the output end of the pusher 18 penetrates through the end of the extrusion cylinder 602, and the output end of the pusher 18 acts on the auxiliary bag 4.

[0049] In this embodiment, the high-pressure outlet 610 of the extrusion cylinder 602 can spray high-pressure gas. When the filter bag is desliming, the high-pressure gas is sprayed towards the filter bag to assist in the desliming process, further reducing the difficulty of operation for the operator. At the same time, the high-pressure gas can blow the chlor-alkali sludge at the bottom of the extrusion cylinder 602 toward the outlet to ensure the desliming effect. The pusher 18 is designed to avoid poor dewatering effect when the chlor-alkali sludge is difficult to dewater. When the components of the chlor-alkali sludge are difficult to dewater, after the dewatering of the rotating roller 605 is completed, the lifting component 3 remains stationary, and the pushing component is a multi-stage hydraulic cylinder. The pushing end of the pushing component pushes the chlor-alkali sludge and the auxiliary bag 4 into the filter bag, and the extrusion roller 5 repeatedly squeezes. After repeated extrusion, a higher dewatering effect can be obtained.

[0050] Furthermore, it also includes a first pawl 19, which is oscillatingly mounted on the extrusion cylinder 602. A first ratchet 20 is mounted on the first gear 12. The first pawl 19 is used to engage or disengage with the first ratchet 20. A second pawl 21 is oscillatingly mounted on the extrusion cylinder 602. A second ratchet 22 is mounted on the second gear 13. The second pawl 21 is used to engage or disengage with the second ratchet 22. One end of a first elastic member 23 acts on the extrusion cylinder 602, and the other end acts on the first pawl 19, providing a force for the first pawl 19 to engage with the first ratchet 20. One end of a second elastic member 24 acts on the extrusion cylinder 602, and the other end acts on the second ratchet 22, providing a force for the second pawl 21 to engage with the second ratchet 22.

[0051] In this embodiment, the first pawl 19 engages with the first ratchet 20, and the second pawl 21 engages with the second ratchet 22, acting on the first gear 12 and the second gear 13 respectively. When the gears rotate in the forward direction, the pawl does not obstruct their movement; however, when the gears tend to rotate in the reverse direction, the pawl immediately engages the ratchet, preventing the gears from reversing. In the salt mud treatment equipment, this design is crucial for precisely controlling the positions of the lifting component 3 and the pressure plate 8. When adjusting the height of the lifting component 3 to control the position of the auxiliary bag 4, once the desired position is reached, the engagement of the pawl and ratchet prevents the first screw 9 from accidentally reversing, ensuring that the auxiliary bag 4 remains stable in that position, thereby guaranteeing uniform force and dehydration effect of the salt mud during the extrusion process. Similarly, for the height adjustment of the pressure plate 8, the action of the second pawl 21 and the second ratchet 22 also ensures its stable position, providing continuous and stable pre-extrusion and shaping effect for the salt mud. By preventing gear reversal, the equipment can maintain the stable position of each component throughout the salt mud treatment process, thereby ensuring that the salt mud treated each time receives the same degree of extrusion and dehydration. This helps improve the consistency of dehydration quality and avoids problems such as insufficient dehydration or excessive compression in certain areas due to unstable component positions.

[0052] Furthermore, the extrusion cylinder 602 also has a water outlet 608, which is located on one side of the mud outlet 606.

[0053] In this embodiment, the water outlet 608 on the extrusion cylinder 602 is located on the same side as the mud outlet 606. During the salt mud treatment process, as the extrusion operation proceeds, the water in the salt mud is continuously squeezed out. The presence of the water outlet 608 allows this squeezed-out water to be discharged from the equipment in a timely manner, preventing water accumulation inside the equipment and affecting the subsequent dewatering effect. From the entry of the salt mud into the equipment for extrusion and dewatering to the final discharge of the dewatered salt mud and water, each step is closely connected, improving production efficiency. The separate discharge of water outlet 608 from the mud outlet 606 facilitates subsequent resource recycling.
