Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and more specifically, to a sludge concentration filter press device and a use method thereof. Background Art

[0002] Sludge is a viscous substance produced during sewage treatment. It is mainly composed of aerobic and anaerobic microorganisms, and is also mixed with mud, sand, fiber, animal and plant residues and organic matter adsorbed on them, metals, bacteria, insect eggs, colloids and other complex mixtures contained in the original sewage. The composition of sludge varies greatly, and varies with the source of sewage, sewage treatment process and season. Treatment and remediation of sludge stored upstream of landfills is of great significance to improving the quality of the environment around landfills.

[0003] Before the sludge is filtered, it needs to be concentrated to reduce the water content in the sludge. The purpose of sludge concentration is to initially reduce the volume of the sludge and reduce the volume of the subsequent treatment structure or equipment capacity. The common sludge concentration method is gravity concentration, which usually requires mixing the sludge with a dehydrating solidifying agent and then placing it in a sedimentation tank. After the sludge settles, the supernatant is pumped away and the sludge is then filtered.

[0004] However, the device still has certain shortcomings in use. When using the above method, it is necessary to wait for enough sludge sedimentation time, and the sedimentation tank also needs to be large enough to handle a large amount of sludge, and the investment cost is high. Based on the above problems, we provide a sludge concentration filter press device. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a sludge thickening filter press device and a method for using the same.

[0006] The sludge concentration filter press device provided by the present invention adopts the following technical solution:

[0007] A sludge concentration filter press device, comprising:

[0008] A sludge channel, connected to an inlet box and an outlet box at the front and rear ends of the sludge channel respectively;

[0009] The concentrating mechanism is installed on the top of the sludge channel and is used to salvage the sludge in the sludge channel to dehydrate and concentrate the sludge;

[0010] The filter press mechanism is installed at the rear of the outlet box to further squeeze and dehydrate the sludge;

[0011] The conveying mechanism is installed between the concentrating mechanism and the filter pressing mechanism, and is used to connect the concentrating mechanism and the filter pressing mechanism and to stir the sludge evenly;

[0012] The concentrating mechanism is disc-shaped in appearance, with a central shaft installed for rotation inside. A support ring is sleeved on the central shaft, and the width of the support ring is the same as the width of the inner cavity of the concentrating mechanism. The support ring and the inner wall of the concentrating mechanism are kept in sliding fit. The outer surface of the support ring is equidistantly installed with multiple salvage frames in a radial shape. The salvage frame at the bottom extends into the sludge channel, and a filter is also installed on the side of the salvage frame in the direction of rotation.

[0013] The filter press mechanism is a rectangular frame structure, and two baffles are fixedly installed inside. The two baffles are symmetrically arranged about the center line of the filter press mechanism. An extrusion plate is also slidably arranged between the two baffles, and a water seepage plate is installed on one side of the baffle facing the extrusion plate.

[0014] A dispersing impeller is also installed inside the conveying mechanism, and a driving motor is installed outside the conveying mechanism, and the output shaft of the driving motor extends into the conveying mechanism and is connected to the shaft core rod of the dispersing impeller.

[0015] Preferably, the salvage frame is also equipped with a material return mechanism, which includes a push plate, which slides closely against the inner edge of the salvage frame equipped with a filter screen, and constraint arms are connected to both sides of the push plate, which extend to the outside of the salvage frame and slide closely against the outer wall of the salvage frame. Guide rods are also installed on the outer walls on both sides of the salvage frame, and the constraint arms are slidably mounted on the corresponding guide rods.

[0016] Preferably, a tension spring is also provided on the guide rod, one end of the tension spring is connected to the outer wall of the salvage frame, the other end of the tension spring is connected to the restraint arm, and the elastic force of the tension spring is smaller than the gravity of the push plate.

[0017] Preferably, the ends of the two restraining arms are also equipped with U-shaped frames, and the side of the U-shaped frame close to the salvage frame where the filter is installed is also equipped with a rubber plate, and the rubber plate slides closely against the outer edge of the filter.

[0018] Preferably, a plurality of partition plates are installed in the filter press mechanism along the direction perpendicular to the baffle frame, and a partition cavity is formed between adjacent partition plates. The partition cavities are of the same size, and an extrusion plate is slidably arranged in the partition cavity. A bottom plate is also movably arranged at the bottom of the filter press mechanism, and a plurality of extrusion plates are connected to the bottom plate. When the extrusion plate slides to be extruded and matched with the baffle frame on one side, an outlet for sludge to fall will be formed between the bottom plate and the baffle frame on the other side.

[0019] Preferably, water outlet pipes are installed at both ends of the baffle frame, and the water outlet pipes extend to the outside of the filter press mechanism.

[0020] Preferably, a slide rail is installed at the bottom center of the base plate, and one end of a folding rod is slidably fitted in the slide rail. A swing motor is also installed below the base plate. The swing motor is located below the center point of the filter press mechanism, and the output shaft of the swing motor is connected to the other end of the folding rod.

[0021] Preferably, the shaft core rod of the dispersing impeller extends outside the conveying mechanism and is equipped with a small pulley, one end of the central shaft extends outside the concentrating mechanism and is equipped with a large pulley, and the same belt is installed on the large pulley and the small pulley for transmission.

[0022] Preferably, a threaded conveying rod is rotatably arranged in the inlet box along the axial direction of the sludge channel, and a feed motor is installed at the outer end of the inlet box. The output shaft of the feed motor extends into the inlet box and is connected to the threaded conveying rod. A mud retaining net is also installed in the outlet box.

[0023] The present invention also provides a method for using a sludge concentration filter press device, comprising the following steps:

[0024] S1: The butt-jointed pipe provided on the inlet box can conveniently input the sludge into the inlet box. When the feeding motor is started, the threaded conveying rod can be rotated. Through the rotation of the threaded conveying rod, the sludge can be continuously input into the sludge channel. The sludge retaining net provided in the outlet box can preliminarily filter the sludge and discharge the water in the sludge to the outside.

[0025] S2: The central shaft can be driven to rotate by the transmission cooperation of the large pulley, the small pulley and the belt. When the central shaft drives the support ring to rotate in the filter press mechanism, the multiple salvage frames installed on the support ring will successively pick up the sludge from the sludge channel and pass through the filter screen installed on the side of the salvage frame. When the salvage frame rotates upward, the water in the sludge will flow out through the filter screen and be concentrated to a certain extent. When the salvage frame flips over the top, the sludge is poured to the conveying mechanism. Through the cooperation of the conveying mechanism, the sludge can be transported to the filter press mechanism for further extrusion and dehydration treatment. The dispersing impeller installed in the conveying mechanism can also break up the sludge when it rotates in cooperation to prevent the sludge from agglomerating and adhering to the conveying mechanism.

[0026] S3: At the same time, when the salvage frame is at the bottom, the push plate in the pushing mechanism will be close to the bottom of the salvage frame because the gravity of the push plate is greater than the elastic force of the tension spring. When salvaging sludge, the sludge will accumulate on the push plate. Then, as the salvage frame is continuously turned upward, the push plate will continuously slide in the salvage frame under the gravity of the push plate, and push the sludge out of the salvage frame for easy cleaning. Furthermore, when the restraint arm slides along the outer side of the salvage frame, it can also push the U-shaped frame and the rubber plate to slide along the filter screen, so that the sludge blocking the filter screen can be easily scraped away, which is convenient for repeated salvage operations.

[0027] S4: Through the cooperation of the conveying mechanism, the sludge can be transported to the filter press mechanism. With the cooperation of the swing motor, the folding rod can also be pushed to rotate, and due to the sliding cooperation between the folding rod and the slide rail, the bottom plate can be pushed to swing back and forth in the filter press mechanism. When the extrusion plate on the bottom plate slides back and forth in the separation chamber, it can cooperate with the baffle frame on the corresponding side to extrude and dehydrate the sludge, and a water seepage plate is also provided on the side of the baffle frame facing the extrusion plate. In the process of squeezing the sludge, water will penetrate into the baffle frame and be discharged through the outlet pipe. After that, when the bottom plate slides to the other side, an outlet for the sludge to fall will be formed between the corresponding baffle frame, which is convenient for discharging the sludge downward. Continuous extrusion and dehydration operations can be performed, and sludge dehydration work can be carried out continuously, which reduces the investment cost of the equipment and is more practical.

[0028] In summary, the present invention includes the following beneficial technical effects:

[0029] 1. The sludge can be initially filtered by the mud retaining net arranged in the outlet box, and the moisture in the sludge channel can be discharged outward through the outlet box. The support ring installed in the concentration mechanism can salvage the sludge from the sludge channel while driving multiple salvage frames to rotate continuously. In the process of the salvage frame rotating from bottom to top, the moisture in the sludge inside the salvage frame is filtered out through the filter screen. When the salvage frame flips over the highest point, the sludge inside the salvage frame will also pour obliquely downward into the conveying mechanism due to the effect of gravity, and through the cooperation of the conveying mechanism, the sludge is conveyed to the filter press mechanism for further extrusion and dehydration. The equipment is simple and can operate continuously, which can effectively reduce the cost investment and is more practical.

[0030] 2. In order to further enable the sludge to be poured out from the salvage frame and transported to the filter press mechanism, a pushing mechanism is also provided in the salvage frame. The push plate provided in the salvage frame will be located at the bottom when the sludge is salvaged because the gravity is greater than the elastic force of the tension spring. When the salvage frame continuously rotates upward, the push plate will gradually slide into the salvage frame under the influence of gravity. During the sliding process, the sludge in the salvage frame can be pushed out to facilitate discharge.

[0031] 3. At the same time, in order to further dehydrate the sludge, when the sludge enters the filter press mechanism through the conveying mechanism, the cooperation of the folding rod and the slide rail can push the bottom plate to swing continuously in the pressure mechanism, thereby pushing the extrusion plate to swing in the separation chamber, and the sludge input from the input mechanism will fall into each separation chamber. When the extrusion plate pushes the sludge to be squeezed toward the baffle frame, the moisture in the sludge can be squeezed into the inside of the baffle frame through the seepage plate and discharged through the set discharge pipe. The squeezed sludge is bonded into blocks. When the bottom plate slides toward the baffle frame on the other side, an outlet for the sludge to fall will appear between the bottom plate and the bottom of the corresponding baffle frame, thereby discharging the agglomerated sludge downward.

DETAILED DESCRIPTION

[0043] The following is combined with Figures 1 to 10 The present invention is described in further detail.

[0044] It should be noted that the drawings are schematic and not to scale. For the sake of clarity and convenience, the relative sizes and proportions of the parts shown in the drawings are exaggerated or reduced in size, and any size is only illustrative and not restrictive. In addition, the same reference symbol is used for the same structure, element or accessory appearing in more than two figures to reflect similar features.

[0045] The embodiment of the invention discloses a sludge concentrating filter pressing device.

[0046] Embodiment 1

[0047] Reference Figure 1 , 2 , 3, 4, 5, 8, 9, a sludge concentration filter press device, comprising:

[0048] A sludge channel 1, an inlet box 2 and an outlet box 4 connected to the front and rear ends of the sludge channel 1 respectively;

[0049] The concentrating mechanism 3 is mounted on the top of the sludge channel 1 and is used to salvage the sludge in the sludge channel 1 to dehydrate and concentrate the sludge;

[0050] The filter press mechanism 5 is installed at the rear of the outlet box 4 and is used to further squeeze and dehydrate the sludge;

[0051] The conveying mechanism 6 is installed between the concentrating mechanism 3 and the filter pressing mechanism 5, and is used to connect the concentrating mechanism 3 and the filter pressing mechanism 5, and to stir the sludge;

[0052] The concentrating mechanism 3 is disc-shaped in appearance, and a central shaft 31 is rotatably installed inside. A support ring 32 is sleeved on the central shaft 31, and the width of the support ring 32 is the same as the width of the inner cavity of the concentrating mechanism 3. The support ring 32 and the inner wall of the concentrating mechanism 3 are kept in sliding fit. The outer surface of the support ring 32 is equidistantly installed with multiple salvage frames 33 in a radial shape. The salvage frame 33 at the bottom extends into the sludge channel 1, and a filter screen 34 is also installed on the side of the salvage frame 33 in the rotation direction.

[0053] Specifically, since the central axis 31 can drive the support ring 32 to rotate continuously, the salvage frame 33 arranged on the support ring 32 can be rotated into the sludge channel 1 in turn to salvage the sludge from the sludge channel. When the salvage frame 33 is turned over from bottom to top, the sludge will be spread on the filter screen 34, and part of the water in the sludge will be separated through filtration by the filter screen 34, thereby achieving the purpose of concentration treatment.

[0054] The filter press mechanism 5 is a rectangular frame structure, and two baffles 52 are fixedly installed inside. The two baffles 52 are symmetrically arranged about the center line of the filter press mechanism 5. An extrusion plate 54 is also slidably arranged between the two baffles 52, and a water seepage plate 521 is installed on one side of the baffle 52 facing the extrusion plate 54.

[0055] In order to further dehydrate the sludge, after the sludge falls into the filter press mechanism 5, the squeezing plate 54 continuously slides between the two baffle frames 52, so that the sludge falling into the filter press mechanism 5 can be squeezed and dehydrated, and the seepage plate 521 installed on the baffle frame 52 can allow water to penetrate into the baffle frame 52 for discharge, thereby realizing the separation of sludge and water and completing the sludge dehydration work.

[0056] A dispersing impeller 62 is also installed inside the conveying mechanism 6 , and a driving motor 63 is installed outside the conveying mechanism 6 , and the output shaft of the driving motor 63 extends into the conveying mechanism 6 and is connected to the shaft core rod 61 of the dispersing impeller 62 .

[0057] Specifically, since the driving motor 63 can also drive the dispersing impeller 62 to rotate, the dispersing impeller 62 can break up the sludge in the conveying mechanism 6 when rotating, so as to prevent the sludge from sticking to form lumps and adhering to the inside of the conveying mechanism 6 and being difficult to separate.

[0058] Reference Figure 2 A threaded conveying rod 21 is also rotatably provided in the inlet box 2 along the axial direction of the sludge channel 1, and a feeding motor 22 is installed at the outer end of the inlet box 2. The output shaft of the feeding motor 22 extends into the inlet box 2 and is connected to the threaded conveying rod 21. A mud retaining net 41 is also installed in the outlet box 4. The sludge entering the inlet box 2 can be gradually conveyed into the sludge channel 1 with the cooperation of the threaded conveying rod 21, so that it is convenient for the salvage frame 33 to pick it up for concentration treatment. The excess water in the sludge channel 1 can be filtered through the mud retaining net 41 into the outlet box 4, and then discharged to the outside, thereby preliminarily reducing the water content in the sludge.

[0059] Reference Figure 3 , 6 The salvage frame 33 is also equipped with a material return mechanism, which includes a push plate 331, which slides closely against the inner edge of the salvage frame 33 equipped with the filter screen 34, and restraining arms 332 are connected to both sides of the push plate 331. The restraining arms 332 extend to the outside of the salvage frame 33 and slide closely against the outer wall of the salvage frame 33. Guide rods 333 are also installed on the outer walls of the corresponding two sides of the salvage frame 33, and the restraining arms 332 are slidably sleeved on the corresponding guide rods 333, so as to achieve the desired effect. In order to effectively dump out the sludge in the salvage frame 33, the push plate 331 arranged in the salvage frame 33 can slide close to the inner side of the filter screen 34, and the guide rod 333 installed on the salvage frame 33 can cooperate with the constraint arm 332 to support the push plate 331 to slide stably. When the salvage frame 33 slides from bottom to top, the push plate 331 can slide in the salvage frame 33, which is convenient for pushing the sludge in the salvage frame 33 and pouring it out.

[0060] Reference Figure 3, 6 The guide rod 333 is also provided with a tension spring 334, one end of which is connected to the outer wall of the salvage frame 33, and the other end of the tension spring 334 is connected to the constraint arm 332. The elastic force of the tension spring 334 is less than the gravity of the push plate 331. With the cooperation of the tension spring 334, the salvage frame 33 will not directly hit the inner wall of the salvage frame 33 when it rotates from bottom to top, thereby playing a buffering role. Moreover, the gravity of the push plate 331 is greater than the elastic force of the tension spring 334. When the salvage frame 33 rotates to the lowest point, the push plate 331 will also be located at the bottom, and the salvaged sludge will also accumulate above the push plate 331.

[0061] Reference Figure 3 , 5 The shaft core rod 61 of the dispersing impeller 62 extends to the outside of the conveying mechanism 6 and is equipped with a small pulley 64. One end of the central shaft 31 extends to the outside of the concentrating mechanism 3 and is equipped with a large pulley 312. The large pulley 312 and the small pulley 64 are driven by the same belt 313. Since the large pulley 312 and the small pulley 64 are equipped with the same belt, when the shaft core rod 61 rotates, the central shaft 31 can be pushed to rotate together.

[0062] Reference Figure 8 , 9 , 10. A plurality of partition plates 51 are also installed in the filter press mechanism 5 along the direction perpendicular to the baffle frame 52. A partition cavity is formed between adjacent partition plates 51. The partition cavities are of the same size, and an extrusion plate 54 is slidably arranged in the partition cavity. A bottom plate 53 is also movably arranged at the bottom of the filter press mechanism 5. A plurality of extrusion plates 54 are all connected to the bottom plate 53. When the extrusion plate 54 slides to be extruded and matched with the baffle frame 52 on one side, an outlet for sludge to fall is formed between the bottom plate 53 and the baffle frame 52 on the other side. Water outlet pipes 55 are also installed at both ends of the baffle frame 52, and the water outlet pipes 55 extend to the outside of the filter press mechanism 5. Due to the action of the partition plates 51, a plurality of partition cavities can be divided, and the sludge can be extruded and dehydrated in the plurality of partition cavities. It is relatively easy to cooperate, and the dehydration efficiency is easy to ensure.

[0063] Reference Fig.10 A slide rail 531 is also installed at the bottom center of the bottom plate 53, and one end of a folding rod 532 is slidably matched in the slide rail 531. A swing motor 534 is also installed below the bottom plate 53. The swing motor 534 is located below the center point of the filter press mechanism 5, and the output shaft of the swing motor 534 is connected to the other end of the folding rod 532. Due to the characteristics of the folding rod 532, when driven by the swing motor 534, the folding rod 532 will make a circular axis motion along the output shaft of the swing motor 534. At the same time, the cooperation between the folding rod 532 and the slide rail 531 can push the bottom plate 53 to slide back and forth, which is convenient for pushing the extrusion plate 54 to be extruded and matched with the baffle frames 52 on both sides.

[0064] Embodiment 2

[0065] Reference Figure 7 The difference between the second embodiment and the first embodiment is that: the ends of the two restraining arms 332 are also equipped with U-shaped frames 335, and the U-shaped frames 335 are also equipped with rubber plates 336 on the sides of the salvage frame 33 where the filter screen 34 is installed. The rubber plates 336 slide closely against the outer edge of the filter screen 34. When the U-shaped frames 335 follow the restraining arms 332 to slide on the guide rods 333, they can also push the rubber plates 336 to slide closely against the outer surface of the filter screen 34, thereby being able to scrape away the sludge blocked in the filter screen 34, making it convenient to continuously filter and concentrate the sludge.

[0066] The present invention also provides a method for using a sludge concentration filter press device, comprising the following steps:

[0067] S1: The butt joint provided on the inlet box 2 can conveniently input the sludge into the inlet box 2. When the feeding motor 22 is started, the threaded conveying rod 21 can be rotated. Through the rotation cooperation of the threaded conveying rod 21, the sludge can be continuously input into the sludge channel 1. The sludge retaining net 41 provided in the outlet box 4 can preliminarily filter the sludge and discharge the water in the sludge to the outside.

[0068] S2: The central shaft 31 can be driven to rotate by the transmission cooperation of the large pulley 312, the small pulley 64 and the belt 313. When the central shaft 31 drives the support ring 32 to rotate in the filter press mechanism 5, the multiple salvage frames 33 mounted on the support ring 32 will successively pick up the sludge from the sludge channel 1, and pass through the filter screen 34 installed on the side of the salvage frame 33. When the salvage frame 33 rotates upward, the water in the sludge will flow out through the filter screen 34, and be concentrated to a certain extent. When the salvage frame 33 turns over and exceeds the top, the sludge is poured to the position of the conveying mechanism 6. Through the cooperation of the conveying mechanism 6, the sludge can be transported to the filter press mechanism 5 for further extrusion and dehydration treatment. When the dispersing impeller 62 mounted in the conveying mechanism 6 rotates in cooperation, the sludge can also be broken up to prevent the sludge from agglomerating and adhering to the conveying mechanism 6.

[0069] S3: At the same time, when the salvage frame 33 is at the bottom, the push plate 331 in the pushing mechanism will be close to the bottom of the salvage frame 33 because the gravity of the push plate 331 is greater than the elastic force of the tension spring 334. When salvaging sludge, the sludge will accumulate on the push plate 331. Then, as the salvage frame 33 is continuously turned upward, the push plate 331 will continuously slide in the salvage frame 33 under the gravity, and push the sludge out of the salvage frame 33 for easy cleaning. Furthermore, when the restraining arm 332 slides along the outer side of the salvage frame 33, it can also push the U-shaped frame 335 and the rubber plate 336 to slide along the filter screen 34, so that the sludge blocking the filter screen 34 can be easily scraped away, which is convenient for repeated salvage operations.

[0070] S4: Through the cooperation of the conveying mechanism 6, the sludge can be transported to the filter press mechanism 5. With the cooperation of the swing motor 534, the folding rod 532 can also be pushed to rotate, and due to the sliding cooperation between the folding rod 532 and the slide rail 531, the bottom plate 53 can be pushed to swing back and forth in the filter press mechanism 5. When the extrusion plate 54 on the bottom plate 53 slides back and forth in the separation chamber, it can cooperate with the baffle frame 52 on the corresponding side to extrude and dehydrate the sludge. The side of the baffle frame 52 facing the extrusion plate 54 is also provided with a seepage plate 521. In the process of squeezing the sludge, water will penetrate into the baffle frame 52 and be discharged through the outlet pipe 55. After that, when the bottom plate 53 slides to the other side, an outlet for the sludge to fall will be formed between the bottom plate 53 and the corresponding baffle frame 52, so that the sludge can be discharged downward conveniently. The extrusion and dehydration operation can be carried out continuously, and the sludge dehydration work can be carried out continuously, which reduces the investment cost of the equipment and is more practical.

The cavities are of the same size, and a squeezing plate (54) is slidably arranged in the separation cavity. A bottom plate (53) is also movably arranged at the bottom of the filter press mechanism (5). The plurality of squeezing plates (54) are all connected to the bottom plate (53). When the squeezing plates (54) slide to squeeze and fit with the baffle frame (52) on one side, an outlet for sludge to fall is formed between the bottom plate (53) and the baffle frame (52) on the other side. Water outlet pipes (55) are also installed at the two ends of the baffle frame (52), and the water outlet pipes (55) extend to the outside of the filter press mechanism (5); A slide rail (531) is also installed at the bottom center of the bottom plate (53), and one end of a folding rod (532) is slidably arranged in the slide rail (531).

2. A sludge concentration filter press device according to claim 1, characterized in that: The shaft core rod (61) of the dispersing impeller (62) extends outside the conveying mechanism (6) and is equipped with a small belt pulley (64), one end of the central shaft (31) extends outside the concentrating mechanism (3) and is equipped with a large belt pulley (312), and the large belt pulley (312) and the small belt pulley (64) are driven by the same belt (313).

3. The sludge concentration filter press device according to claim 1, characterized in that: A threaded conveying rod (21) is also rotatably provided in the inlet box (2) along the axial direction of the sludge channel (1), and a feed motor (22) is installed at the outer end of the inlet box (2), the output shaft of the feed motor (22) extends into the inlet box (2) and is connected to the threaded conveying rod (21), and a mud retaining net (41) is also installed in the outlet box (4).

4. The method for using the sludge concentration filter press device according to any one of claims 1 to 3, characterized in that: include: S1: The butt joint provided on the inlet box (2) can facilitate the input of sludge into the inlet box (2). When the feed motor (22) is started, the threaded conveying rod (21) can be rotated. Through the rotation of the threaded conveying rod (21), the sludge can be continuously input into the sludge channel (1). The sludge retaining net (41) provided in the outlet box (4) can preliminarily filter the sludge and discharge the water in the sludge to the outside. S2: The central shaft (31) can be driven to rotate by the transmission cooperation between the large pulley (312), the small pulley (64) and the belt (313). When the central shaft (31) drives the support ring (32) to rotate in the filter press mechanism (5), a plurality of salvaging frames (33) mounted on the support ring (32) will sequentially salvage the sludge from the sludge channel (1) and pass through the filter screen (34) installed on the side of the salvaging frame (33). When the salvaging frame (33) rotates upward, the sludge is discharged. The water in the mud will flow out through the filter screen (34) and be concentrated to a certain extent. When the salvage frame (33) turns over and exceeds the top, the mud will be poured out to the conveying mechanism (6). Through the cooperation of the conveying mechanism (6), the mud can be conveyed to the filter press mechanism (5) for further squeezing and dehydration treatment. The dispersing impeller (62) installed in the conveying mechanism (6) can also break up the mud when it rotates in cooperation, so as to prevent the mud from agglomerating and adhering to the conveying mechanism (6). S3: At the same time, when the salvage frame (33) is at the bottom, the push plate (331) in the pushing mechanism will be in close contact with the bottom of the salvage frame (33) because the gravity of the push plate (331) is greater than the elastic force of the tension spring (334). When salvaging sludge, the sludge will accumulate on the push plate (331). Then, as the salvage frame (33) is continuously turned upward, the push plate (331) will continuously slide in the salvage frame (33) under the gravity, and push the sludge out of the salvage frame (33) for easy cleaning. Furthermore, when the restraining arm (332) slides along the outer side of the salvage frame (33), it can also push the U-shaped frame (335) and the rubber plate (336) to slide along the filter screen (34), so that the sludge blocking the filter screen (34) can be easily scraped away, facilitating repeated salvaging operations. S4: Through the cooperation of the conveying mechanism (6), the sludge can be conveyed to the filter pressing mechanism (5). With the cooperation of the swing motor (534), the folding rod (532) can be driven to rotate. Moreover, due to the sliding cooperation between the folding rod (532) and the slide rail (531), the bottom plate (53) can be driven to swing back and forth in the filter pressing mechanism (5). When the squeezing plate (54) on the bottom plate (53) slides back and forth in the partition chamber, it can cooperate with the baffle frame (52) on the corresponding side to squeeze the sludge. The sludge is squeezed and dehydrated, and a water seepage plate (521) is provided on the side of the baffle frame (52) facing the squeezing plate (54). During the squeezing process of the sludge, water will penetrate into the baffle frame (52) and be discharged through the outlet pipe (55). Then, when the bottom plate (53) slides to the other side, an outlet for the sludge to fall is formed between the bottom plate (53) and the corresponding baffle frame (52), so that the sludge can be discharged downwards conveniently. The squeezing and dehydration operation can be carried out continuously, and the sludge dehydration work can be carried out continuously, thereby reducing the investment cost of the equipment and being more practical.
