Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and in particular to a bifurcated bottom-turning type chlor-alkali salt sludge treatment device and a treatment method thereof. Background Art

[0002] Salt sludge treatment has always been a crucial step in chlor-alkali industrial production. Traditional chlor-alkali salt sludge treatment methods often present numerous challenges. During the dehydration process, the salt sludge often exhibits uneven distribution due to a lack of effective pretreatment and rational extrusion process design. Consequently, pressure cannot be evenly applied to all parts of the salt sludge during the subsequent extrusion dehydration operation, resulting in localized overpressure or underpressure.

[0003] When local pressure is too high, the salt mud may be over-extended, which not only damages the structure of the salt mud, but also may cause some water to be compacted and difficult to drain, which also increases equipment wear and energy consumption. If the local pressure is too low, the water cannot be effectively squeezed out, resulting in poor dehydration of the salt mud, causing excessive moisture content in some areas, and affecting the overall quality stability of the salt mud.

[0004] Furthermore, due to its unique location, the middle portion of the salt mud has a relatively long water drainage path, making it difficult to fully dehydrate using traditional treatment methods. This results in a high water content in this portion of the salt mud, which seriously affects the dehydration quality of the entire salt mud and is not conducive to subsequent recycling or further processing of the salt mud. These issues urgently require a new salt mud treatment technology to improve the uniformity, efficiency, and quality of salt mud dehydration to meet the needs of industrial production and environmental protection requirements.

[0043] A forked bottom-turning type chlor-alkali salt mud treatment method uses a forked bottom-turning type chlor-alkali salt mud treatment device.

[0044] The working principle and beneficial effects of the present invention are:

[0045] In the present invention, compared to the treatment of chlor-alkali salt mud in the prior art, the squeezing roller first performs a preliminary squeezing on the salt mud in the filter bag to remove a large amount of free water. Then, the bifurcated roller flips the salt mud and pushes it into the auxiliary bag. When the bifurcated roller pushes the filter bag into the auxiliary bag, the chlor-alkali salt mud that has undergone preliminary dehydration can be evenly distributed between the filter bag and the auxiliary bag. When the subsequent extruder squeezes the auxiliary bag, the pressure can be more evenly transmitted to each part of the salt mud. Compared with the situation where the salt mud is unevenly distributed, the problem of excessive or insufficient local pressure will not occur, so that the water in the salt mud can be squeezed out more evenly. This helps to improve the overall uniformity of dehydration, ensure that the entire salt mud body reaches a similar degree of dehydration, and avoid the problem of unstable salt mud quality caused by local dehydration differences, such as excessively high or low water content in some areas.

[0046] Evenly distributed salt mud can better adapt to pressure changes during the extrusion process, allowing water to drain more easily from the mud. Under uniform pressure, the gaps between salt mud particles more effectively form drainage channels, promoting the rapid flow and drainage of water. Compared to the potential water blockage or retention caused by uneven distribution, this uniform distribution speeds up dehydration and improves dehydration efficiency.

[0047] The flipping action of the bifurcated rollers exposes the difficult-to-dehydrate portion of the salt sludge to the outside for subsequent repeated extrusion. During the further extrusion process between the auxiliary bag and the extrusion element, these previously difficult areas are more fully dehydrated, thereby improving overall dehydration efficiency and shortening the time required to reach the desired dehydration level.

[0048] The central portion of the salt sludge is difficult to drain due to its unique location. By rotating and pushing the forked rollers, and by focusing the squeeze on this portion of the salt sludge with the auxiliary bag and squeeze element, the moisture in the central portion is effectively removed. This repeated squeezing action ensures effective dehydration of the central portion, reducing its moisture content and improving dehydration quality. This results in a more ideal salt sludge state, facilitating subsequent recycling or further processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0060] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0061] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0062] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0063] Reference Figures 1 to 8, which is the first embodiment of the present invention, provides a forked bottom-turning chlor-alkali salt mud processing equipment for dehydrating chlor-alkali salt mud in cylindrical filter bags, including a frame 1, a fixing member 2 is arranged on the frame 1, the fixing member 2 has a first fixing hole 201 and a second fixing hole 203, the first fixing hole 201 and the second fixing hole 203 are arranged coaxially and are respectively located on both sides of the fixing member 2, the first fixing hole 201 is used to fix the filter bag, the lifting member 3 is lifted relative to the fixing member 2 and is located on one side of the second fixing hole 203, the auxiliary bag 4 is arranged on the lifting member 3, the diameter of the auxiliary bag 4 is larger than the diameter of the filter bag, the squeezing roller 5 is lifted and arranged on the frame 1, the squeezing roller 5 is configured to squeeze the filter bag when lifting and lowering, the squeezing member 6 is arranged on the frame 1, the squeezing member 6 has an squeezing cavity 601, the auxiliary bag 4 and the lifting member 3 are both located in the squeezing cavity 601, the squeezing member 6 is used to squeeze the auxiliary bag 4, the forked roller 7 is lifted and arranged on the frame 1, and the forked roller 7 pushes the filter bag into the auxiliary bag 4 after rising.

[0064] In this embodiment, the frame 1 provides a stable support for the entire apparatus, ensuring accurate assembly and stable operation of all components, and withstanding the various forces and loads generated during operation. The fixing member 2 securely secures the filter bag containing the chlor-alkali salt sludge to the apparatus via the first fixing hole 201, preventing displacement of the filter bag during processing and ensuring accurate and stable processing. The lifting member 3 drives the auxiliary bag 4 upward and downward. This movement prevents the filter bag from being unable to desludge after dehydration. It should be noted that the lifting member 3 is an annular structure with several clearance holes to avoid interference with other components. The auxiliary bag 4 has a larger diameter than the filter bag, providing more space for the initially dehydrated salt sludge and facilitating subsequent extrusion and dehydration. The squeezing roller 5 applies pressure to the salt sludge in the filter bag through its lifting action, squeezing out moisture, achieving initial dehydration and paving the way for more complete dehydration. The squeezing member 6 compresses the auxiliary bag 4 containing the salt sludge, applying even stronger pressure to further remove moisture and improve dehydration efficiency. When the bifurcated roller 7 rises, the salt mud in the filter bag is turned over, so that the part in the middle that is not easy to dehydrate can be exposed to the outside for repeated squeezing. 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 processing process.

[0065] Compared to the treatment of chlor-alkali salt mud in the prior art, the squeezing roller 5 first performs a preliminary squeezing on the salt mud in the filter bag to remove a large amount of free water. Next, the bifurcated roller 7 flips the salt mud and pushes it into the auxiliary bag 4. When the bifurcated roller 7 pushes the filter bag into the auxiliary bag 4, the chlor-alkali salt mud that has undergone preliminary dehydration can be evenly distributed between the filter bag and the auxiliary bag 4. When the subsequent squeezing member 6 squeezes the auxiliary bag 4, the pressure can be more evenly transmitted to each part of the salt mud. Compared to the situation where the salt mud is unevenly distributed, there will be no problem of excessive or insufficient local pressure, so that the water in the salt mud can be squeezed out more evenly. This helps to improve the overall uniformity of dehydration, ensure that the entire salt mud body reaches a similar degree of dehydration, and avoid the problem of unstable salt mud quality caused by local dehydration differences, such as excessively high or low water content in some areas.

[0066] Evenly distributed salt mud can better adapt to pressure changes during the extrusion process, allowing water to drain more easily from the mud. Under uniform pressure, the gaps between salt mud particles more effectively form drainage channels, promoting the rapid flow and drainage of water. Compared to the potential water blockage or retention caused by uneven distribution, this uniform distribution speeds up dehydration and improves dehydration efficiency.

[0067] The flipping action of the bifurcated rollers 7 exposes the central, less-drainable portion of the salt sludge to the outside for subsequent repeated extrusion. During the further extrusion process by the auxiliary bag 4 and the extrusion element 6, these previously difficult-to-treat areas are more fully dehydrated, thereby improving overall dehydration efficiency and shortening the time required to achieve the desired dehydration level.

[0068] The central portion of the salt sludge is difficult to drain due to its unique location. The flipping and pushing of the bifurcated rollers 7, along with the focused squeezing of this portion by the auxiliary bag 4 and the extruder 6, effectively removes the moisture from the central portion. This repeated squeezing action ensures effective dehydration of the central portion, reducing its moisture content and improving dehydration quality. This results in a more ideal salt sludge state, facilitating subsequent recycling or further processing.

[0069] Furthermore, it also includes a pressure plate 8, which is slidably arranged in the extrusion cavity 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 lifted, 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 forked roller 7.

[0070] In this embodiment, after the auxiliary bag 4 passes through the through-hole 801 of the pressing plate 8, the through-hole 801 of the pressing plate 8 can apply additional pressure to the salt mud within the auxiliary bag 4. Before the extruder 6 extrudes the auxiliary bag 4, the pressing plate 8 restricts the expansion of the auxiliary bag 4 from all sides, so that the salt mud within the auxiliary bag 4 is pre-extruded. The chlor-alkali salt mud is shaped through the through-hole, further improving the dehydration effect during extrusion by the extruder 6. This dual extrusion action can more effectively remove moisture from the salt mud, especially for bound water that remains after initial dehydration or moisture that is difficult to expel. Through the auxiliary shaping of the pressing plate 8, the moisture 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 dehydration quality.

[0071] The sliding setting of the pressing plate 8 can play a certain role in adjusting the distribution and shape of the salt mud during the lifting and lowering process of the auxiliary bag 4. When the bifurcated roller 7 rises, the salt mud is affected by the combined action of the auxiliary bag 4 and the pressing plate 8 in the extrusion chamber 601, and will be more evenly distributed in the auxiliary bag 4, avoiding the salt mud from locally accumulating or forming uneven blocks. At the same time, the diameter of the through hole 801 of the pressing plate 8 is slightly larger than the diameter of the bifurcated roller 7. This design can limit the excessive flow of the salt mud to a certain extent, keeping it within an appropriate range, which is beneficial to the subsequent extrusion dehydration operation and ensuring that the salt mud is always in a state conducive to dehydration during the entire processing process.

[0072] Furthermore, it also includes a first screw 9, the first screw 9 is rotatably set on the extrusion member 6, the lifting member 3 has a first threaded hole, the lifting member 3 is threadedly connected to the first threaded hole, the first screw 9 has a first gear portion 901, the second screw 10 is rotatably set on the extrusion member 6, the pressure plate 8 has a second threaded hole, the second screw 10 is threadedly connected to the second threaded hole, the second screw 10 has a second gear portion 1001, the swing lifting member 11 is swinging and lifting and setting on the frame 1, the first gear 12 is rotatably set on the extrusion member 6, the first gear 12 is an inner ring gear, and the first gear 12 is connected to the inner ring gear. The first gear portion 901 is meshed and arranged, and the second gear 13 is rotatably arranged on the extrusion member 6. The second gear 13 is a double-sided gear ring. The second gear 13 has a third tooth portion 1301, and the third tooth portion 1301 is meshed with the second gear portion 1001. The third gear 14 is rotatably arranged at one end of the swing lifting member 11, and the fourth gear 15 is meshed with the third gear 14. After the swing lifting member 11 swings, the fourth gear 15 is meshed with the first gear 12 or the second gear 13. After the swing lifting member 11 rises, the fourth gear 15 is away from the first gear 12 and the second gear 13.

[0073] In this embodiment, the threaded connection between the first screw 9 and the lifting member 3, and the threaded connection between the second screw 10 and the pressing plate 8, realize the precise control of the lifting and lowering movement of the lifting member 3 and the pressing plate 8. By rotating the first screw 9 and the second screw 10, the height position of the lifting member 3 and the pressing plate 8 can be precisely adjusted according to the different stages and requirements of the salt mud treatment. This precise control helps to optimize the distribution and extrusion process of the salt mud within the equipment, so that the salt mud can be in the best state in different processing steps. For example, after the salt mud is initially dehydrated, the lifting member 3 is precisely controlled to install the auxiliary bag 4 to the side of the second fixing hole 203 so that the filter bag enters the auxiliary bag 4, achieving more effective secondary extrusion dehydration. The design of the first gear 12 and the second gear 13 increases the stability and precision of the gear transmission. The first gear 12 and the third tooth portion 1301 are respectively engaged with the first gear portion 901 of the first screw 9 and the second gear portion 1001 of the second screw 10, so that the transmission of force during rotation is smoother, the impact of the gap and shaking between the gears on the lifting control is reduced, and the accuracy of the lifting movement is further improved, ensuring that the equipment can operate according to the predetermined parameters during operation, thereby improving the quality and consistency of the dehydration process.

[0074] The combined design of the swinging lifter 11, third gear 14, fourth gear 15, first gear 12, and second gear 13 achieves efficient power transmission and coordinated operation between components. The swinging and lifting motion of the swinging lifter 11 flexibly transmits power to the first gear 12 or second gear 13 via the third gear 14 and fourth gear 15, thereby driving the rotation of the first screw 9 or second screw 10. This design allows a single power source to control the movement of multiple components, simplifying the equipment's power system and improving its overall efficiency. During the salt mud processing process, each component can operate sequentially or simultaneously as needed. For example, when the auxiliary bag 4 needs to be squeezed, the swinging lifter 11 swings, causing the fourth gear 15 to engage with the first gear 12, driving the first screw 9 to rotate, raising and lowering the lifter 3, and thereby controlling the position and degree of squeezing of the auxiliary bag 4. When the position of the pressing plate 8 needs to be adjusted, the swinging lifter 11 swings in the opposite direction, causing the fourth gear 15 to engage with the third tooth portion 1301, driving the second screw 10 to rotate and precisely adjust the height of the pressing plate 8. The coordinated work of various components ensures that the equipment can operate efficiently in different processing stages, improving the equipment's degree of automation and processing capabilities.

[0075] Furthermore, the pressure plate 8 has a slide groove 802, the extrusion member 6 includes an extrusion cylinder 602, the extrusion cylinder 602 is arranged 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 set on the extrusion cylinder 602, there are two pupil valves 603, which are respectively located at the upper and lower ends of the extrusion chamber 601, the pupil valve 603 has an opening and closing valve plate 604, the opening and closing valve plates 604 are arranged in several circles, there are several rotating rollers 605, the two ends of the rotating roller 605 are respectively set on the opening and closing valve plates 604 of the two pupil valves 603, and the rotating roller 605 is slidably set in the slide groove 802.

[0076] In this embodiment, the extrusion barrel 602 provides a stable extrusion space. The extrusion chamber 601 within it 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 barrel 602, facilitating coordination with other components for precise control of the extrusion process. The design of the pupil valve 603 adds 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 salt mud extrusion process, the opening and closing valve plates 604 are closed, and the rotating rollers 605 abut and squeeze the auxiliary bag 4. The ends of the multiple 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 as the shape and pressure of the salt mud change, ensuring more uniform extrusion of the salt mud. At the same time, 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, thereby preventing the salt mud from sticking or clogging during the extrusion process and ensuring the smooth progress of the extrusion process.

[0077] The combined design of the extrusion cylinder 602, the pupil valve 603 and the 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 sturdy structure and can withstand greater pressure, ensuring that it will not be deformed or damaged during the extrusion process. The two ends of the rotating roller 605 are arranged on the opening and closing valve plate 604, which increases the stability of the entire structure and prevents the rotating roller 605 from deflecting or falling off during the extrusion process. This stable structural design enables the equipment to maintain good performance during long-term operation, reduces the incidence of equipment failures, and improves the reliability and service life of the equipment.

[0078] Furthermore, the extruding member 6 is rotatably mounted on the frame 1 , the lifting member 3 is lifted relative to the frame 1 , and the rotating roller 605 is configured so as to abut against the auxiliary bag 4 .

[0079] In this embodiment, when the extruder 6 rotates, the rotating rollers 605 rotate synchronously and abut against the auxiliary bag 4. This design can achieve all-round and uniform extrusion of the salt mud in the auxiliary bag 4. As the extruder 6 rotates, the rotating rollers 605 apply pressure to the salt mud at different positions, avoiding the problem of excessive or uneven local pressure that may be caused by the traditional fixed extrusion method. Each rotating roller 605 continuously acts on the salt mud at different angles, so that the moisture in the salt mud can be squeezed out more evenly, thereby improving the dehydration efficiency and dehydration quality. The continuous rotation and extrusion of the rotating rollers 605 can also repeatedly knead the salt mud, further destroying the structure of the salt mud and making it easier to release the moisture therein. This kneading-like effect helps to improve the dehydration effect of the salt mud, especially for those salt muds with high viscosity or tight structure, which can effectively break the internal moisture binding force and improve the dehydration efficiency.

[0080] The synchronized rotation of the extruder 6 and the rotating rollers 605 enhances the stability of the equipment. During the extrusion process, the contact between the rotating rollers 605 and the auxiliary bag 4 provides stable support, preventing excessive deformation or displacement of the auxiliary bag 4. Furthermore, the even distribution and synchronized rotation of the rotating rollers 605 ensure a smoother extrusion process, reducing the risk of vibration and damage to the equipment caused by uneven localized pressure or sudden force.

[0081] Furthermore, the extrusion cylinder 602 has a mud outlet 606, which is located on the end side of the extrusion cylinder 602 close to the fixing member 2. The forked roller 7 has an abutment end 701 and also includes a vibrating member 16. The vibrating member 16 is arranged on the frame 1. The forked roller 7 is configured so that when it rises to the highest point, the output end of the vibrating member 16 abuts against the abutment end 701, and the spiral conveying member 17 is arranged at the mud outlet 606.

[0082] In this embodiment, the lifting member 3 rises, driving the auxiliary bag 4 to rise, and at the same time, the filter bag is buckled in the extrusion chamber 601 under the continuous action of the forked roller 7. At this time, the vibrating member 16 is started, and its output end abuts against the abutting end 701 of the forked roller 7, generating vibration that is transmitted to the equipment, loosening the salt mud. The spiral conveying member 17 is started, and the spiral conveying member 17 located at the mud outlet 606 of the extrusion cylinder 602 transports the dehydrated salt mud to the designated position. During the mud discharge process, the vibrating member 16 continues to work, assisting the smooth discharge of the salt mud, ensuring the smoothness and thoroughness of the mud discharge process, and reducing salt mud residue.

[0083] When mud removal is required, the lifting member 3 rises, driving the auxiliary bag 4 upward. Under the continuous action of the bifurcated roller 7, the filter bag is inverted within the extrusion chamber 601. This coordinated action creates a structural change that facilitates mud removal. The inverted filter bag exposes the salt mud to the outside, facilitating mud removal. At the same time, the rising auxiliary bag 4 scrapes the salt mud, facilitating its removal.

[0084] The coordinated action of the lifting element 3, forked roller 7, and other components makes the sludge discharge process more orderly and efficient. Compared to traditional sludge discharge methods, this design can significantly shorten sludge discharge time. In traditional methods, salt sludge can be difficult to discharge due to accumulation and adhesion inside the filter bag, requiring a long time to clean. However, this device, through operations such as flipping the filter bag in reverse, allows the salt sludge to fall off quickly, reducing obstructions during the sludge discharge process and thus increasing the sludge discharge speed. The flipping filter bag operation can effectively reduce the amount of salt sludge remaining inside the device. During the sludge discharge process, the salt sludge can be discharged more thoroughly from the device, avoiding accumulation and clogging of the device. Different chlor-alkali salt sludges may have different characteristics such as humidity, viscosity, and particle size. The sludge discharge design of this device, through the flipping of the filter bag, the rising of the auxiliary bag 4, and the coordinated action of the vibrating element 16 and the screw conveyor 17, can adapt to the sludge discharge needs of salt sludge with different characteristics. For salt sludge with high humidity and strong viscosity, the vibrating element 16 can effectively loosen the salt sludge. The rising of the auxiliary bag 4 and the inverted buckling of the filter bag provide greater squeezing force, making the salt sludge easier to discharge. For salt sludge with larger particles, the spiral conveying element 17 can adjust according to the particle size to ensure smooth conveying. This adaptability enables the equipment to maintain excellent mud discharge performance when handling various types of salt sludge, improving its versatility and practicality.

[0085] Furthermore, the extrusion cylinder 602 has an air cavity 609, the air cavity 609 has a high-pressure outlet 610, and the high-pressure outlet 610 is arranged in a plurality of rows on the inner wall of the extrusion cavity 601. It also includes a pusher 18 arranged at the end of the extrusion cylinder 602 away from the fixing member 2, and the output end of the pusher 18 passes through the end of the extrusion cylinder 602, and the output end of the pusher 18 acts on the auxiliary bag 4.

[0086] In this embodiment, the high-pressure outlet 610 of the extrusion barrel 602 can spray high-pressure gas. When the filter bag is desludging, the high-pressure gas is sprayed toward the filter bag to assist in desludging the filter bag, further reducing the difficulty of the operator in desludging the filter bag. At the same time, the high-pressure gas can blow the chlor-alkali salt mud at the bottom of the extrusion barrel 602 toward the outlet, ensuring the desludging effect. The design of the pushing member 18 is to avoid poor dehydration effect when the chlor-alkali salt mud is difficult to dehydrate. When the components of the chlor-alkali salt mud are difficult to dehydrate, after the rotating roller 605 completes dehydration, the lifting member 3 does not move. The pushing member is a multi-stage hydraulic cylinder. The pushing end of the pushing member pushes the chlor-alkali salt mud and the auxiliary bag 4 into the filter bag. The extrusion roller 5 repeats the extrusion. After repeated multiple times, a higher dehydration effect can be achieved.

[0087] Furthermore, it also includes a first pawl 19, which is swingably set on the extrusion cylinder 602, and the first ratchet 20 is set on the first gear 12. The first pawl 19 is used to engage with or cancel the engagement with the first ratchet 20, and the second pawl 21 is swingably set on the extrusion cylinder 602, and the second ratchet 22 is set on the second gear 13. The second pawl 21 is used to engage with or cancel the engagement with the second ratchet 22. One end of the first elastic member 23 acts on the extrusion cylinder 602, and the other end acts on the first pawl 19, providing force for the first pawl 19 to engage with the first ratchet 20, and one end of the second elastic member 24 acts on the extrusion cylinder 602, and the other end acts on the second ratchet 22, providing force for the second pawl 21 to engage with the second ratchet 22.

[0088] 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 are rotating in the forward direction, the pawl does not impede their movement. However, when the gears tend to reverse, the pawl immediately engages the ratchet, preventing the gears from reversing. In salt mud processing equipment, this design is crucial for precisely controlling the position of the lifting member 3 and the pressing plate 8. When adjusting the height of the lifting member 3 to control the position of the auxiliary bag 4, once the desired position is reached, the coordination of the pawl and ratchet prevents accidental reversal of the first screw 9, ensuring that the auxiliary bag 4 remains in this position, thus ensuring uniform force and dehydration of the salt mud during the extrusion process. Similarly, when adjusting the height of the pressing plate 8, the second pawl 21 and second ratchet 22 ensure its position remains stable, providing continuous and stable pre-extrusion and shaping for the salt mud. By preventing gear reversal, the equipment maintains the stable position of each component throughout the salt mud processing process, ensuring that each treatment of the salt mud receives the same degree of extrusion and dehydration. This helps improve the consistency of dehydration quality and avoids problems such as localized insufficient dehydration or excessive squeezing due to unstable component positioning.

[0089] Furthermore, the extrusion cylinder 602 also has a water outlet 608 , which is located on one side of the mud outlet 606 .

[0090] In this embodiment, the water outlet 608 provided on the extrusion cylinder 602 is located on the side of the mud outlet 606. During the salt mud processing process, as the extrusion operation proceeds, water in the salt mud is continuously squeezed out. The presence of the water outlet 608 allows this squeezed water to be promptly discharged from the equipment, preventing water accumulation within the equipment and affecting the subsequent dehydration effect. From the time the salt mud enters the equipment for extrusion dehydration to the final discharge of the dehydrated salt mud and water, each link is closely connected, improving production efficiency. The separate discharge of the water outlet 608 and the mud outlet 606 facilitates subsequent resource recycling.
