Description

Technical Field

[0001] This utility model relates to the field of sludge conveying, specifically a multi-stage feeding filtration mechanism for sludge conveying. Background Technology

[0002] Sludge transport refers to the process of safely and efficiently transferring sludge from its source (such as a wastewater treatment plant) to a treatment, disposal, or resource utilization site using equipment such as pipelines, pumps, or vehicles. Multi-stage feed filtration mechanisms used for sludge transport are sludge treatment equipment that combine multi-stage filtration and continuous feeding functions. They are designed to improve sludge filtration efficiency, prevent clogging, and achieve continuous automated operation.

[0003] In the existing technology, when sludge is transported by a threaded conveyor, the outlet size of the threaded conveyor is smaller than the cylinder size, which causes the sludge to be squeezed and agglomerated under high pressure when passing through the conveyor outlet, increasing the risk of clogging the conveying mechanism. At the same time, the sludge may contain a small amount of clumps, making it difficult to filter the sludge encased in the clumps during filtration. The existing sludge conveying and filtering mechanism is not convenient for breaking up clumps before filtration, which reduces the filtration effect of the sludge. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that sludge is squeezed and agglomerated under high pressure when passing through the outlet of the conveyor, making it difficult to break up the clumps before filtration, this utility model proposes a multi-stage feeding and filtration mechanism for sludge conveying.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-stage feeding filter mechanism for sludge conveying, comprising a conveying cylinder, a spiral conveying assembly rotatably connected inside the conveying cylinder, a softening assembly connected to a flange at one end of the conveying cylinder, and a multi-stage filter cylinder connected to a flange at one end of the softening assembly.

[0006] The spiral conveyor assembly includes a variable pitch threaded conveyor rod rotatably connected inside the conveyor cylinder. One end of the variable pitch threaded conveyor rod is fixedly connected to a transmission rod A, and one end of the transmission rod A is splinedly connected to the output end of a servo motor A.

[0007] The softening component includes a connecting pipe with a flange connected to one end of the conveying cylinder. An impact block is slidably connected to the inner surface of the connecting pipe. A connecting rod is fixedly connected to one end of the impact block. A rotating rod is rotatably connected to one end of the connecting rod. A turntable is rotatably connected to one end of the rotating rod. A B transmission rod is fixedly connected to one end of the turntable. One end of the B transmission rod is splinedly connected to the output end of the B servo motor.

[0008] Preferably, a base plate is fixedly connected to the bottom of the conveying cylinder, and a multi-stage filter cylinder is fixedly connected to the top of the base plate.

[0009] Preferably, the surface of the A servo motor is fixedly connected to the A motor box, and a conveyor cylinder is fixedly connected to one side of the A motor box.

[0010] Preferably, a fixing ring is fitted onto the surface of the A motor box, a bracket is fixedly connected to the bottom of the fixing ring, and a base plate is fixedly connected to the bottom of the bracket.

[0011] Preferably, a connecting plate is fixedly connected to the top edge of the base plate, a B-type transmission rod is connected through the surface of the connecting plate, and a turntable is rotatably connected to one side of the connecting plate.

[0012] Preferably, a B motor box is fixedly connected to the other side of the connecting plate, and a B servo motor is fixedly connected inside the B motor box.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, through the structural setting of the screw conveyor assembly, allows sludge to be fed into the conveying cylinder, and then the A servo motor is connected to the power supply and powered on, so that the A transmission rod drives the variable pitch screw conveyor rod to rotate. The pitch of the variable pitch screw conveyor rod gradually increases, so that the sludge is gradually spread evenly during the conveying process, and sufficient space is left for the sludge at the output port to prevent the sludge from being subjected to large pressure and sticking together, thereby reducing the risk of clogging the conveying mechanism.

[0015] 2. This utility model, through the structural design of the softening component, connects the B servo motor to the power supply before the sludge flows into the multi-stage filter cartridge. This causes the B transmission rod to drive the turntable. When the turntable rotates, it drives one end of the rotating rod to rotate, causing the rotating rod to drive the connecting rod to reciprocate. This causes the connecting rod to push the impact block to repeatedly impact the sludge flowing through the connecting pipe. This allows the sludge conveying and filtering mechanism to break up clumps of sludge before filtering, thus improving the sludge filtering effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a multi-stage feeding filtration mechanism for sludge conveying includes a conveying cylinder 1, a spiral conveying assembly 2 rotatably connected inside the conveying cylinder 1, a softening assembly 3 connected to one end flange of the conveying cylinder 1, and a multi-stage filter cylinder 4 connected to one end flange of the softening assembly 3.

[0024] The screw conveyor assembly 2 includes a variable pitch threaded conveyor rod 201 rotatably connected inside the conveyor cylinder 1. One end of the variable pitch threaded conveyor rod 201 is fixedly connected to a transmission rod 202 A. One end of the transmission rod 202 A is splinedly connected to the output end of a servo motor 203 A.

[0025] The softening component 3 includes a connecting pipe 301 with a flange connected to one end of the conveying cylinder 1. An impact block 302 is slidably connected to the inner surface of the connecting pipe 301. A connecting rod 303 is fixedly connected to one end of the impact block 302. A rotating rod 304 is rotatably connected to one end of the connecting rod 303. A turntable 305 is rotatably connected to one end of the rotating rod 304. A B transmission rod 306 is fixedly connected to one end of the turntable 305. One end of the B transmission rod 306 is splinedly connected to the output end of the B servo motor 307.

[0026] During operation, the sludge is fed into the conveying cylinder 1 via the spiral conveyor assembly 2. Then, servo motor A 203 is connected to the power supply, causing transmission rod A 202 to drive the variable-pitch threaded conveyor rod 201 to rotate. The pitch of the variable-pitch threaded conveyor rod 201 gradually increases, allowing the sludge to be gradually spread evenly during transport. Sufficient space is provided at the output port to prevent the sludge from adhering under excessive pressure, reducing the risk of clogging the conveying mechanism. Through the softening assembly 3, before the sludge flows into the multi-stage filter cylinder 4, servo motor B 307 is connected to the power supply, causing transmission rod B 306 to drive turntable 305. The rotation of turntable 305 causes one end of rotating rod 304 to rotate, which in turn drives connecting rod 303 to reciprocate. This causes connecting rod 303 to push impact block 302 to repeatedly impact the sludge flowing through connecting pipe 301, enabling the sludge conveying and filtering mechanism to break up clumps before filtration, thus improving the sludge filtration effect.

[0027] Furthermore, a base plate 5 is fixedly connected to the bottom of the conveying cylinder 1, and a multi-stage filter cylinder 4 is fixedly connected to the top of the base plate 5.

[0028] When in operation, the footprint of the mechanism can be defined by the base plate 5, which facilitates planning.

[0029] Furthermore, a motor housing 6 is fixedly connected to the surface of servo motor A 203, and a conveyor cylinder 1 is fixedly connected to one side of motor housing A 6;

[0030] During operation, the A servo motor 203 can be protected and secured by the A motor box 6.

[0031] Furthermore, a fixing ring 7 is fitted onto the surface of motor box 6, a bracket 8 is fixedly connected to the bottom of the fixing ring 7, and a base plate 5 is fixedly connected to the bottom of the bracket 8.

[0032] During operation, by setting up the fixing ring 7 and the bracket 8, the A servo motor 203 can be fixed at a suitable height by supporting the A motor box 6, so that the A transmission rod 202 can be connected to the variable pitch threaded conveyor rod 201.

[0033] Furthermore, a connecting plate 9 is fixedly connected to the top edge of the base plate 5, and a B transmission rod 306 is connected through the surface of the connecting plate 9. A turntable 305 is rotatably connected to one side of the connecting plate 9.

[0034] During operation, the connecting plate 9 provides support for the turntable 305, reducing the load on the B transmission rod 306.

[0035] Furthermore, a B motor box 10 is fixedly connected to the other side of the connecting plate 9, and a B servo motor 307 is fixedly connected inside the B motor box 10.

[0036] During operation, the B servo motor 307 can be protected and supported by the B motor box 10.

[0037] Working principle: After the sludge is fed into the conveying cylinder 1, the A servo motor 203 is connected to the power supply and energized, causing the A transmission rod 202 to drive the variable pitch threaded conveying rod 201 to rotate. The pitch of the variable pitch threaded conveying rod 201 gradually increases, so that the sludge is gradually spread evenly during the conveying process, and sufficient space is left at the output port to prevent the sludge from being squeezed and stuck. Before the sludge flows into the multi-stage filter cartridge 4, it first flows into the connecting pipe 301. The B servo motor 307 is connected to the power supply and energized, causing the B transmission rod 306 to drive the turntable 305. When the turntable 305 rotates, it drives one end of the rotating rod 304 to rotate, causing the rotating rod 304 to drive the connecting rod 303 to reciprocate. This causes the connecting rod 303 to push the impact block 302 to repeatedly impact the sludge flowing through the connecting pipe 301.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
