Description

Technical Field

[0001] This utility model relates to the technical field of wastewater solid-liquid separators, specifically a rotary drum solid-liquid separator for wastewater treatment. Background Technology

[0002] A rotary drum solid-liquid separator is a device that uses a rotary drum structure to achieve solid-liquid separation. It uses the centrifugal force generated by the rotation of the screen to trap suspended solids with low water resistance, thus achieving efficient solid-liquid separation.

[0003] However, due to their hygroscopic nature, the solids separated by existing rotary drum solid-liquid separators may retain some moisture, making subsequent processing difficult. In addition, if there are large solids, they may clog the discharge port or the grid holes of the grid frame, thereby reducing the separation effect of the rotary drum solid-liquid separator. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary drum solid-liquid separator for wastewater treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rotary drum solid-liquid separator for wastewater treatment includes:

[0007] The material hopper is fixedly connected to the bottom of the sewage channel via a crossbeam support. One side of the sewage channel is an inlet, from which sewage is transported to the outlet. The bottom of the material hopper has a sewage inlet facing the sewage pipe inlet. A riser pipe is fixedly connected to the material hopper for transporting waste from the sewage. A pressing cylinder is fixedly connected to the riser pipe for squeezing out residual sewage from the waste. A discharge port is opened on the lower end face of the upper cylinder of the pressing cylinder, and a reducer is fixedly connected above the discharge port.

[0008] Preferably, the material hopper is installed obliquely inside the sewage pipe, and a baffle plate is fixedly connected to the inlet of the sewage pipe.

[0009] Preferably, a grid frame is rotatably connected inside the material hopper for separating waste from sewage. Preferably, a reinforcing plate is fixedly connected between the material hopper and the riser pipe, and a spiral blade is rotatably connected inside the riser pipe, the spiral blade being rotatably connected to the grid frame.

[0010] Preferably, the pressing cylinder is a cylindrical body with a filter medium and a spiral shaft inside.

[0011] Preferably, a cutting part is fixedly connected below the discharge port, and the cutting part contains a cutting blade.

[0012] Preferably, the output end of the reducer is rotatably connected to the spiral shaft inside the pressing cylinder, the spiral shaft is rotatably connected to the spiral blades inside the riser pipe, and the spiral blades are rotatably connected to the grid frame inside the material hopper.

[0013] Preferably, the riser pipe is connected to the stabilizing support via a retaining ring.

[0014] Preferably, an anti-clogging pipe is fixedly connected to the material hopper, the anti-clogging pipe is connected to an external water source and a pressing cylinder pipe, and the anti-clogging pipe is provided with multiple water outlets.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention separates solids and liquids inside wastewater through the cooperation of a speed reducer, a pressing cylinder, a riser pipe, and a grid frame. The liquid enters the wastewater channel outlet, while the solids enter the pressing cylinder for further separation and are then transported out from the discharge port for subsequent processing. The cooperation of these components ensures the separation of liquids and solids in the wastewater, facilitating subsequent recycling and processing.

[0017] In this invention, a cutting section is installed below the discharge port. The cutting section contains multiple cutting blades. The solid separated by the grid frame falls from the discharge port to the cutting section below through the riser pipe and the pressing cylinder. The solid is then cut into small pieces by the cutting blades for easy subsequent processing.

[0018] In this invention, an anti-clogging pipe is fixedly connected to the top of the material hopper. The anti-clogging pipe is connected to the pressing cylinder pipe. When the pressing cylinder squeezes and separates the residual liquid, the separated liquid is sprayed again from the spray nozzle on the anti-clogging pipe through the pump. The liquid pressurized by the pump is sprayed onto the material hopper and the grid frame, causing the solids blocking the grid holes to detach, thereby preventing clogging. When the separated liquid is small, since the anti-clogging pipe is connected to an external water source, external clean water can also be introduced to clean and remove blockages from the grid holes.

Detailed Implementation

[0021] 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 protection scope of the present utility model. Example

[0022] Please see Figure 1 This utility model provides a technical solution:

[0023] A rotary drum solid-liquid separator for wastewater treatment includes:

[0024] Material hopper 2 is fixedly connected to the bottom of sewage channel 10 via crossbeam support 1. One side of sewage channel 10 is inlet 11, from which sewage is transported to outlet 12. The bottom of material hopper 2 has a sewage inlet facing the sewage inlet 11. A riser pipe 6 is fixedly connected to material hopper 2 for transporting garbage in sewage. A pressing cylinder 7 is fixedly connected to the riser pipe 6 for squeezing out residual sewage from the garbage. An outlet 8 is opened on the lower end face of the upper cylinder of pressing cylinder 7. A reducer 9 is fixedly connected above the outlet 8.

[0025] In this embodiment, the bottom material hopper 2 of the rotary drum solid-liquid separator is fixedly connected to the sewage channel 10 via a crossbeam support 1. The bottom of the material hopper 2 is the sewage inlet. The material hopper 2 is installed at an angle, with one side of its bottom facing the inlet 11 of the sewage channel 10. The sewage to be treated flows from the inlet 11 of the sewage channel 10 to the outlet 12 on the other side, preferentially contacting the sewage inlet at the bottom of the material hopper 2 along the way. Under the guidance of the baffle plate 5, it enters the material hopper 2. The inside of the material hopper 2 has a grid frame 4, which is rotatably connected inside the material hopper 2. At the same time, the grid frame 4 is connected to the inside of the upper riser pipe 6. The spiral blades are rotatably connected, and the spiral blades are connected to the spiral shaft inside the pressing cylinder 7. The spiral shaft is rotatably connected to the output end of the reducer 9. When the reducer 9 starts, the reducer 9 drives the grid frame 4 to rotate continuously through transmission. The surface of the grid frame 4 is covered with a mesh filter or grid holes. The high-speed rotation of the grid frame 4 generates a strong centrifugal force. Based on the sieving effect and centrifugal sedimentation, the solids are trapped on the inner wall of the grid frame 4 because their size is larger than the grid holes. The separated liquid penetrates the grid holes under the action of centrifugal force, leaves the grid frame 4 and the material hopper 2, and is guided by the baffle plate 5 to prevent splashing or backflow before entering the outlet 12.

[0026] The separated solids are rotated by the spiral blades inside the rising pipe 6 fixedly connected above the grid frame 4. The spiral blades drive the separated solids upward and convey them to the pressing cylinder 7 above. The pressing cylinder 7 is equipped with a filter medium (such as a filter screen or filter cloth) and a spiral shaft is installed inside the cylinder. As the separated solids rise, the space inside the cylinder gradually decreases and the pressure on the material gradually increases, further separating the solids and liquids. The separated liquid is discharged through the filter medium, and the further separated solids continue to rise and are discharged from the discharge port 8.

[0027] Specifically, the material hopper 2 is installed obliquely inside the sewage pipe, and a baffle plate 5 is fixedly connected to the inlet 11 of the sewage pipe.

[0028] Specifically, the material hopper 2 is internally connected to a grid frame 4 for separating garbage from sewage.

[0029] Specifically, a reinforcing plate 201 is fixedly connected between the material hopper 2 and the riser pipe 6, and a spiral blade is rotatably connected inside the riser pipe 6, and the spiral blade is rotatably connected to the grid frame 4.

[0030] Specifically, the pressing cylinder 7 is a cylindrical body with a filter medium and a spiral shaft inside.

[0031] Specifically, the output end of the reducer 9 is rotatably connected to the spiral shaft inside the pressing cylinder 7, the spiral shaft is rotatably connected to the spiral blades inside the rising pipe 6, and the spiral blades are rotatably connected to the grid frame 4 inside the material hopper 2.

[0032] Specifically, a fixing ring 602 is connected to the outer wall of the riser pipe 6, and the bottom of the fixing ring 602 is fixedly connected to the stabilizing bracket 601. Example

[0033] Please see Figure 1 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with slight differences:

[0034] Specifically, a cutting part 801 is fixedly connected below the discharge port 8, and the cutting part 801 contains a cutting blade.

[0035] In this embodiment, a cutting section 801 is installed below the discharge port 8. Multiple cutting blades are installed inside the cutting section 801. The solid separated by the grid frame 4 falls from the discharge port 8 to the cutting section 801 below through the riser pipe 6 and the pressing cylinder 7. After being cut by the cutting blades, the separated solid is cut into small pieces for easy subsequent processing. Example

[0036] Please see Figure 1 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with slight differences:

[0037] Specifically, an anti-clogging pipe 3 is fixedly connected to the material hopper 2. The anti-clogging pipe 3 is connected to the external water source and the pressing cylinder 7. Multiple water spray nozzles 301 are provided on the anti-clogging pipe 3.

[0038] In this embodiment, an anti-clogging pipe 3 is fixedly connected to the top of the material hopper 2. The anti-clogging pipe 3 is connected to the pressing cylinder 7. When the pressing cylinder 7 squeezes and separates the residual liquid, the separated liquid is pumped out again from the spray nozzle 301 on the anti-clogging pipe 3. The liquid pressurized by the pump is sprayed onto the material hopper 2 and the grid frame 4, causing the solids blocking the grid holes on the grid frame 4 to detach, thereby preventing blockage. When the separated liquid is small, since the anti-clogging pipe 3 is connected to an external water source, external clean water can also be introduced to clean and remove blockages from the grid holes.

[0039] In use, the bottom material hopper 2 of the rotary drum solid-liquid separator is fixedly connected to the sewage channel 10 via a crossbeam support 1. The bottom of the material hopper 2 is the sewage inlet. The material hopper 2 is installed at an angle, with one side of its bottom facing the inlet 11 of the sewage channel 10. The sewage to be treated flows from the inlet 11 of the sewage channel 10 to the outlet 12 on the other side, preferentially contacting the sewage inlet at the bottom of the material hopper 2. Under the guidance of the baffle plate 5, it enters the material hopper 2. The inside of the material hopper 2 has a grid frame 4, which is rotatably connected inside the material hopper 2. At the same time, the grid frame 4 is connected to the upper riser pipe 6. The internal spiral blades are rotatably connected, and the spiral blades are connected to the spiral shaft inside the pressing cylinder 7. The spiral shaft is rotatably connected to the output end of the reducer 9. When the reducer 9 starts, the reducer 9 drives the grid frame 4 to rotate continuously through transmission. The surface of the grid frame 4 is covered with a mesh filter or grid holes. The high-speed rotation of the grid frame 4 generates a strong centrifugal force. Based on the sieving effect and centrifugal sedimentation, the solids are trapped on the inner wall of the grid frame 4 because their size is larger than the grid holes. The separated liquid penetrates the grid holes under the action of centrifugal force, leaves the grid frame 4 and the material hopper 2, and is guided by the baffle plate 5 to prevent splashing or backflow before entering the outlet 12.

[0040] The separated solids are rotated by the spiral blades inside the rising pipe 6 fixedly connected above the grid frame 4. The spiral blades drive the separated solids upward and convey them to the pressing cylinder 7 above. The pressing cylinder 7 is equipped with a filter medium (such as a filter screen or filter cloth) and a spiral shaft is installed inside the cylinder. As the separated solids rise, the space inside the cylinder gradually decreases and the pressure on the material gradually increases, further separating the solids and liquids. The separated liquid is discharged through the filter medium, and the further separated solids continue to rise and are discharged from the discharge port 8.

[0041] A cutting section 801 is installed below the discharge port 8. Multiple cutting blades are installed inside the cutting section 801. The solids separated by the grid frame 4 fall from the discharge port 8 to the cutting section 801 below through the riser pipe 6 and the pressing cylinder 7. After being cut by the cutting blades, the separated solids are cut into small pieces for easy subsequent processing.

[0042] An anti-clogging pipe 3 is fixedly connected to the top of the material hopper 2. The anti-clogging pipe 3 is connected to the pressing cylinder 7. When the pressing cylinder 7 squeezes and separates the residual liquid, the separated liquid is pumped out again from the spray nozzle 301 on the anti-clogging pipe 3. The liquid pressurized by the pump is sprayed onto the material hopper 2 and the grid frame 4, causing the solids blocking the grid holes on the grid frame 4 to detach, thereby preventing clogging. When the separated liquid is small, since the anti-clogging pipe 3 is connected to an external water source, external clean water can also be introduced to clean and remove blockages from the grid holes.
