Description

Technical Field

[0001] This application relates to the field of sludge treatment technology, specifically to a sludge disposal and reuse device. Background Technology

[0002] Silt refers to fine-grained soil containing organic matter that has been deposited in still or slow-flowing water environments. With the increasing environmental protection requirements in my country, the harmless, reduced-volume, and resource-based treatment of silt generated from water bodies such as rivers, lakes, and ponds has become an urgent task. Silt is rich in organic matter, nitrogen, phosphorus, and other nutrients required by plants. After harmless treatment such as composting, fermentation, or aerobic digestion, it can be made into nutrient soil, greening cultivation substrate, or soil conditioner, and can be recycled after disposal. The initial treatment of sludge containing impurities is usually filtration and separation. However, due to the complex composition of sludge, which not only has a high water content but also usually contains a large number of solid impurities such as plastic products, stones, shells, and branches, the current method of impurity removal is usually to use screens. However, the screen pores are easily clogged, requiring frequent shutdowns for cleaning, which makes continuous and efficient operation impossible and seriously affects the processing efficiency. Therefore, this application proposes a sludge treatment and reuse device. Utility Model Content

[0003] The purpose of this application is to provide a sludge treatment and reuse device in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution: A sludge treatment and reuse device, comprising: The box body is provided with a partition inside, which is used to divide the box body into a cleaning chamber and a dehydration chamber. The box body is provided with a feed inlet and a drain pipe that are respectively connected to the cleaning chamber and the dehydration chamber. A discharge port is provided through the partition. The impurity removal mechanism, located inside the impurity removal chamber, is used to separate impurities from the sludge; The dewatering mechanism, located inside the dewatering chamber, is used to dewater and separate the sludge after impurity removal.

[0005] Furthermore, the impurity removal mechanism includes a guide rod that rotates through the box body, one end of the guide rod is connected to a first motor mounted on the box body, a plurality of connecting plates are fixedly arranged on the guide rod, a plurality of first arc-shaped rods are fixedly arranged on the connecting plates, and an impurity discharge port corresponding to the partition is opened through one side of the box body.

[0006] Furthermore, a guide plate is inclinedly arranged on the inner wall of the box body below the feed inlet, and several clearance grooves are arrayed at the end of the guide plate, and several first arc-shaped rods respectively move through several clearance grooves.

[0007] Furthermore, a support plate is fixedly provided on the partition plate, and a plurality of second arc-shaped rods are arranged in an array on the support plate, with the plurality of second arc-shaped rods being distributed alternately with a plurality of first arc-shaped rods.

[0008] Furthermore, the dehydration mechanism includes a conical mesh cylinder disposed inside the box and open at one end. The open end of the conical mesh cylinder movably penetrates through the box. The conical mesh cylinder is connected to a discharge port via a discharge cylinder. A shaft is coaxially rotatably inserted inside the conical mesh cylinder. One end of the shaft is connected to a second motor disposed on the box. A spiral blade is fixed on the shaft, and the outer edge of the spiral blade abuts and overlaps with the inner wall of the conical mesh cylinder.

[0009] Furthermore, the pitch of the helical blades gradually decreases from the feed end to the open end.

[0010] Furthermore, the conical mesh cylinder includes a first cylinder and a second cylinder that are rotatably connected. The first cylinder is fixed to the inner wall of the box and communicates with the unloading cylinder. The box is provided with a driving component for driving the second cylinder to rotate.

[0011] Furthermore, the driving component includes a rotating rod rotatably mounted on the housing, one end of which is connected to a shaft via a gear assembly, and the other end is connected to the second cylinder via a pulley assembly.

[0012] The beneficial effects of this application are as follows: 1. In this application, the sludge enters the impurity removal chamber through the feed inlet. First, the solid impurities in the sludge are separated by the impurity removal mechanism. After impurity removal, the sludge enters the dewatering chamber through the discharge port. Then, the sludge is dewatered by the dewatering mechanism to separate the sludge from the water. Impurity removal and dewatering are carried out in sequence, which can effectively separate the solid impurities and water carried in the sludge, facilitating the subsequent processing of the sludge.

[0013] 2. In this application, during the removal of impurities from sludge, as the guide rod continues to rotate, several first arc-shaped rods intercept impurities. Under the stress of rotation, the first arc-shaped rods will throw the intercepted solid impurities to the right. The solid impurities are then discharged from the discharge port along the inclined plane. This not only separates solid impurities in the sludge, but also prevents clogging due to centrifugal force and throwing force. Furthermore, the separated solid impurities can be discharged directly without stopping the machine for cleaning, thus ensuring the efficiency of impurity removal and separation.

[0014] 3. In this application, during the dewatering of sludge, the conical screen cylinder structure allows the sludge and water to gradually move from the lower end to the upper end under the push of the spiral blades. During the movement, the water can fall down through the mesh and be discharged from the drain pipe, while the sludge is discharged from the box. During dewatering, the conical structure of the conical screen cylinder makes the conveying space gradually smaller from the feed end to the discharge end. The pushing of the spiral blades gradually increases the pressure on the sludge. By using this pressurization, a gradient dewatering from gentle to intense is achieved, resulting in high dewatering efficiency. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1-8 As shown, an embodiment of this application proposes a sludge treatment and reuse device, comprising: The housing 1 has a partition 2 inside, which divides the housing 1 into a cleaning chamber and a dewatering chamber. The housing 1 has an inlet 3 and a drain pipe 4 that are respectively connected to the cleaning chamber and the dewatering chamber. A discharge port 5 is opened through the partition 2. By opening the discharge port 5 on the partition 2, although the partition 2 divides the housing 1 into a cleaning chamber and a dewatering chamber, the two chambers can be connected, so that the sludge can be cleaned first and then dewatered. The cleaning mechanism 6 is set in the cleaning chamber and is used to separate impurities in the sludge. When the sludge is added into the housing 1 from the inlet 3, the cleaning mechanism 6 first separates the solid impurities in the sludge, and the sludge and the water contained in it enter the dewatering chamber through the discharge port 5 for subsequent processes. The dewatering mechanism 7 is set in the dewatering chamber and is used to dewater the sludge after cleaning. When the sludge after cleaning enters the dewatering chamber, the dewatering mechanism 7 dewaters the sludge and separates the sludge from the water. In this scheme, the sludge enters the impurity removal chamber through the feed inlet 3. First, the solid impurities in the sludge are separated by the impurity removal mechanism 6. After impurity removal, the sludge enters the dewatering chamber through the discharge port 5. Then, the sludge is dewatered by the dewatering mechanism 7 to separate the sludge from the water. Impurity removal and dewatering are carried out in sequence, which can effectively separate the solid impurities and water carried in the sludge, making it easier for the subsequent processing of the sludge.

[0019] like Figure 2 , Figure 3 and Figure 7The specific structure of the impurity removal mechanism 6 of this application is disclosed. The impurity removal mechanism 6 includes a guide rod 601 that rotates through the housing 1. One end of the guide rod 601 is connected to a first motor 602 mounted on the housing 1. Several connecting plates 605 are fixedly arranged on the guide rod 601. Several first arc-shaped rods 603 are fixedly arranged on the connecting plates 605. A discharge port 604 corresponding to the partition 2 is opened through one side of the housing 1. Preferably, the partition 2 has an inverted V-shaped structure with two sloping surfaces, left and right. The discharge port 5 is opened on the left sloping surface, and the feed port 3 is located on the left side of the housing 1. The right end of the partition 2 moves through the discharge port 604. When sludge is added from the feed port 3, the sludge carrying solid impurities and water will fall downwards. At this time, the first motor 602 does work, and its output shaft drives the connecting plate 605 and the several first arc-shaped rods 603 fixed on it to rotate. When sludge carrying solid impurities and water falls downwards, it impacts several first arc-shaped rods 603 located on the same connecting plate 605. Preferably, the gap between two adjacent first arc-shaped rods 603 only allows sludge and water to pass through, while solid impurities are intercepted on them. The sludge and water then slide onto the partition plate 2 and down the left slope, and are discharged into the dewatering chamber through the discharge port 5. As the guide rod 601 continues to rotate, under the stress of rotation, the first arc-shaped rods 603 will throw the intercepted solid impurities to the right, thus throwing the solid impurities onto the right slope of the partition plate 2. The solid impurities are then discharged from the discharge port 604 along the slope. This not only separates solid impurities in the sludge, but also prevents clogging due to centrifugal force and throwing force. Furthermore, the separated solid impurities can be discharged directly without stopping the machine for cleaning, thus ensuring the efficiency of impurity removal and separation.

[0020] like Figure 7 As shown, this application discloses a further technical solution for the impurity removal mechanism 6. A guide plate 8 is inclinedly arranged on the inner wall of the housing 1 and below the feed inlet 3. Several clearance grooves 9 are arrayed at the ends of the guide plate 8. Several first arc-shaped rods 603 respectively move through several clearance grooves 9. By setting the guide plate 8 and opening clearance grooves 9 on the guide plate 8, the first arc-shaped rods 603 that follow the rotation of the guide rod 601 can rotate through the clearance grooves 9, which can better guide the sludge falling from the feed inlet 3 to the rotating first arc-shaped rods 603, so that the sludge can effectively pass through the first arc-shaped rods 603, thereby further ensuring the impurity removal effect.

[0021] like Figure 7As shown, this application discloses a further technical solution for the impurity removal mechanism 6. A support plate 10 is fixed on the partition plate 2, and a plurality of second arc-shaped rods 11 are arranged in an array on the support plate 10. The plurality of second arc-shaped rods 11 are staggered with a plurality of first arc-shaped rods 603. When the first arc-shaped rods 603 intercept solid impurities, during the scattering process, some impurities (such as tree branches with multiple branches) are easily stuck between two adjacent first arc-shaped rods 603, causing them to be unable to be scattered smoothly. By setting the support plate 10 and the second arc-shaped rods 11, as the guide rod 601 rotates, the plurality of second arc-shaped rods 11 are staggered with the plurality of first arc-shaped rods 603, which can peel off the stuck impurities, thereby playing a role in preventing blockage and further improving the impurity removal effect.

[0022] like Figure 3 , Figure 5 , Figure 7 and Figure 8 The specific structure of the dewatering mechanism 7 of this application is disclosed. The dewatering mechanism 7 includes a conical mesh cylinder 701 disposed inside the housing 1 with one end open. The open end of the conical mesh cylinder 701 movably penetrates the housing 1. The conical mesh cylinder 701 is connected to the discharge port 5 via a discharge cylinder 705. A shaft 702 is coaxially rotatably inserted inside the conical mesh cylinder 701. One end of the shaft 702 is connected to a second motor 703 disposed on the housing 1. A spiral blade 704 is fixed on the shaft 702. The outer edge of the spiral blade 704 abuts and overlaps with the inner wall of the conical mesh cylinder 701. Preferably, the conical mesh cylinder 701 is horizontally arranged, with the end with a larger inner diameter connected to the discharge cylinder 705, and the end with a smaller inner diameter being open and movably penetrating the housing 1. After impurity removal, the sludge carrying water enters the conical mesh cylinder 701 through the discharge port 5 and the discharge cylinder 705. The second motor... When 703 performs work, it drives the shaft 702 and the spiral blade 704 to rotate. As the spiral blade 704 rotates, it applies a thrust to the sludge, thus pushing the sludge to move along the right side and being discharged from the box 1 through the opening of the conical mesh cylinder 701. Preferably, the mesh openings on the conical mesh cylinder 701 only allow water to pass through. The structure of the conical mesh cylinder 701 allows the sludge and water to gradually move from the lower end to the higher end under the push of the spiral blade 704. During the movement, water can fall down through the mesh openings and be discharged from the drain pipe 4, while the sludge is discharged from the box 1. During dewatering, the conical structure of the conical mesh cylinder 701 makes the conveying space gradually decrease from the feed end to the discharge end. The pushing of the spiral blade 704 gradually increases the pressure on the sludge. By using this pressurization, a gradient dewatering from gentle to intense is achieved, resulting in high dewatering efficiency.

[0023] like Figure 6As shown, this application discloses a further technical solution for the spiral blade 704. The pitch of the spiral blade 704 gradually decreases from the feed end to the open end. Based on the conical structure, the variable pitch design further improves the pressurization effect. The large pitch at the feed end facilitates rapid feeding and conveying, while the small pitch at the discharge end greatly increases the extrusion pressure, thereby further improving the dewatering effect on sludge.

[0024] like Figure 5 As shown, a further technical solution for the conical mesh cylinder 701 of this application is disclosed. The conical mesh cylinder 701 includes a first cylinder 7011 and a second cylinder 7012 rotatably connected. The first cylinder 7011 is fixed to the inner wall of the box 1 and communicates with the unloading cylinder 705. The box 1 is provided with a driving member 12 for driving the second cylinder 7012 to rotate. By forming the conical mesh cylinder 701 with the first cylinder 7011 and the second cylinder 7012, and rotatably connected, the mesh is actually opened on the second cylinder 7012. The second cylinder 7012 is driven to rotate by the driving member 12. Preferably, the rotation direction of the second cylinder 7012 is opposite to the rotation direction of the shaft 702. The second cylinder 7012 rotates actively and forms relative motion with the spiral blade 704, which completely destroys the adhesion between the sludge and the mesh cylinder, making the mesh less likely to be blocked and ensuring that the dewatering process is carried out continuously and efficiently.

[0025] like Figure 2 As shown, the specific structure of the driving component 12 of this application is disclosed. The driving component 12 includes a rotating rod 1201 rotatably mounted on the housing 1. One end of the rotating rod 1201 is connected to the shaft 702 via a gear assembly 1202, and the other end is connected to the second cylinder 7012 via a pulley assembly 1203. Preferably, the gear assembly 1202 includes a transmission bevel gear and a driven gear respectively fixed on the shaft 702 and the rotating rod 1201, and the teeth of the two are meshed. When the shaft 702 rotates, the meshing of the teeth of the transmission gear and the driven gear drives the rotating rod 1201 to rotate synchronously in the opposite direction. Then, the linkage of the pulley assembly 1203 is used to drive the second cylinder 7012 to rotate. The second cylinder 7012 rotates synchronously in the opposite direction with the shaft 702. The free end of the second cylinder 7012 is constructed with a retaining edge so that the silt falling from its end (open end) will not contact the pulley assembly 1203 and will not affect the stability of its linkage.

[0026] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
