Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a process equipment for the directional separation of organic and inorganic sediments in wastewater treatment plants. Background Technology

[0002] The sediments in wastewater treatment plants must be treated for several reasons: From an environmental safety perspective, sediments often contain large amounts of organic matter, heavy metals, pathogens and other harmful substances. If they are discharged directly without treatment, these substances will be washed into the surrounding water bodies and soil by rainwater, causing eutrophication of water bodies (such as the deterioration of water quality due to the proliferation of algae) and soil pollution (affecting crop growth and even harming human health through the food chain).

[0003] Currently, existing wastewater treatment plant sediment material processing equipment typically has a simple processing flow and limited separation accuracy. Although it can perform simple processing on some materials, it cannot achieve efficient and precise directional separation of sludge materials. This results in the loss of a large amount of recyclable effective carbon sources and effective biochemical bacteria along with the waste, increasing the cost and difficulty of subsequent dewatering treatment. At the same time, incomplete separation also makes it difficult to directly reuse the effluent as a resource. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot achieve efficient and precise directional sorting and separation of sludge materials, resulting in the loss of a large amount of recyclable effective carbon sources and effective biochemical bacteria along with the waste. Therefore, this invention proposes a process equipment for the directional sorting of organic and inorganic sediment materials in wastewater treatment plants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An organic-inorganic directional separation process equipment for sediment materials in a wastewater treatment plant, comprising: The system includes a gravity separation group, a vibration sorting group, a pretreatment group, a washing and separation group, and a sludge removal unit. The gravity separation group is fixedly equipped with a support frame on top, the pretreatment group is fixedly installed on top of the support frame, and the vibration sorting group is fixedly installed on top of the gravity separation group and located next to the support frame.

[0006] In one possible design, the pretreatment group includes a separation mechanism disposed therein, a screenings outlet is provided at the bottom of the upper part of the pretreatment group, an organic-inorganic material outlet is provided on one side of the lower part of the pretreatment group, the organic-inorganic material outlet is connected to the vibrating sorting group through a pipe, and a feed inlet is provided on the side of the pretreatment group away from the screenings outlet, and the feed inlet is connected to the sludge removal unit through a pipe.

[0007] In one possible design, the gravity separation group includes an organic material collection box and an inorganic material collection box. The organic material collection box is fixedly connected to the lower part of the vibration separation group via a pipe, and the inorganic material collection box is fixedly connected to the upper part of the vibration separation group via a pipe.

[0008] In one possible design, the washing and separating unit includes a tank, a stirring motor is fixedly mounted on the top of the tank, a stirring rod is rotatably mounted inside the tank, and stirring blades are fixedly mounted on the outside of the stirring rod. The output shaft of the stirring motor is fixedly connected to the stirring rod. The top of the tank is connected to an inorganic material collection box through a pipe, and a connecting pipe connected to a water supply pipe is fixedly connected to one side of the tank.

[0009] In one possible design, the bottom of the tank is fixedly connected to a conveying pipe, the top of the conveying pipe is fixedly equipped with a conveying motor, a conveying rod is rotatably installed inside the conveying pipe, and a spiral auger is fixedly installed outside the conveying rod. The output shaft of the conveying motor is fixedly connected to the conveying rod, and a discharge port is opened at the bottom of the high part of the conveying pipe.

[0010] In one possible design, a waste bin is placed directly below both the screenings outlet and the discharge port.

[0011] In this application, when the device is first put into use, the entire device is connected to the power supply. Then, the dredging unit transports the dredged material (including the remaining debris, gravel, mud and other sediments that are not completely cleaned by the previous coarse and fine screens) through the pipeline to the feed inlet of the pretreatment unit. The material is fed into the pretreatment group from the feed inlet. The separation mechanism (multiple star disk groups) inside the pretreatment group starts to operate. The multiple star disk groups are driven by chains and sprockets and rotate at high speed under the drive of motors. When the material passes through the star disk group, the high speed of the star disks causes the material to jump locally, effectively breaking the mutual wrapping of organic and inorganic substances and peeling off the organic matter on the surface of sand and gravel. After being processed by the separation mechanism, large debris such as filter residue is discharged from the screenings outlet at the bottom of the pretreatment group and falls into the garbage bin directly below the screenings outlet. The organic-inorganic mixture containing sand, gravel and organic sludge enters the vibrating sorting group through the pipe from the organic-inorganic material outlet on the lower side of the pretreatment group. Materials containing sand and gravel and organic slurry enter the inclined vibrating sorting disc of the vibrating sorting group. By adjusting the vibration frequency and vibration amplitude of the sorting disc, the materials are sorted. Inorganic materials such as sand and gravel are used as oversize materials and enter the inorganic material collection box from the top of the vibrating sorting group through the pipe. Organic slurry (mixture) and fine inorganic materials are used as undersize materials and enter the organic material collection box from the bottom of the vibrating sorting group through the pipe. The organic material collection box collects the organic sludge and mixed liquid separated by the vibration separation group. These materials are returned to the sewage treatment biochemical process section as an effective carbon source and bacteria in the sewage treatment plant. The inorganic material collection box collects the sand and gravel and other inorganic materials separated by the vibration separation group and transports them to the tank of the washing and separation group through pipelines. Inorganic materials such as sand and gravel enter the tank through a pipe from the inorganic material collection box. At this time, the stirring motor drives the stirring rod and its blades to rotate, stirring the inorganic materials in the tank. Simultaneously, a certain amount of reclaimed water is injected into the tank through a connecting pipe connected to the water supply pipe. The sand and gravel are efficiently scrubbed by combining the wall effect and mixing, further cleaning the small amount of organic matter on the surface of the sand and gravel. Then the stirring motor stops working, and gravity sedimentation allows the washed inorganic materials to settle to the bottom. The washing wastewater is discharged to the biological treatment tank through a pipe. At this time, the conveying motor is started. The output shaft of the conveying motor drives the conveying rod and its spiral auger to transport the inorganic materials settled at the bottom of the tank upward in the conveying pipe. Finally, it is discharged from the bottom outlet at the top of the conveying pipe and falls into the garbage bin directly below, where it is reused as building materials and other resources.

[0012] This utility model has the following beneficial effects: This invention, through the setup of a gravity separation group, a vibration sorting group, a pretreatment group, and a washing separation group, enables efficient and precise directional sorting and separation of sludge in wastewater treatment plants, saving significant dewatering costs. It also returns effective carbon sources and effective biochemical bacteria to the original chemical process section, while simultaneously achieving resource reuse of the effluent.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0016] Reference Figure 1-4 A sorting process equipment, comprising: The gravity separation group 1, vibration sorting group 2, pretreatment group 4, washing and separation group 5, and sludge removal group 6 achieve efficient directional sorting of organic and inorganic materials. The top of the gravity separation group 1 is fixedly installed with a support frame 3. The pretreatment group 4 is stably set on the top of the support frame 3, making it higher than the vibration sorting group 2. The vibration sorting group 2 is fixedly set on the top of the gravity separation group 1 and located next to the support frame 3, so that the organic and inorganic materials at the bottom of the pretreatment group 4 flow into the vibration sorting group 2 by gravity.

[0017] Pretreatment group 4 is the key starting part for the entire equipment to achieve efficient sorting. It is equipped with a separation mechanism, which consists of multiple star disk groups. These star disk groups are driven by chains and sprockets and rotate at high speed under the drive of a motor. The pretreatment group 4 has a feed inlet on the side away from the screenings discharge outlet 401. This feed inlet is connected to the sludge removal unit 6 through a pipeline. When the equipment starts working, the sludge removal unit 6 removes the sediment formed by the mutual entanglement of residual debris, gravel, mud, etc., which were not completely removed by the previous coarse and fine screens in the sewage treatment plant. This sediment is the sludge material, which is then transported through the pipeline. The material enters the pretreatment group 4 through the feed inlet. Inside the pretreatment group 4, as multiple star disks in the separation mechanism rotate at high speed, the material jumps locally when passing through the star disks. This process can effectively break the mutual encapsulation of organic and inorganic substances and peel off the organic matter on the surface of sand and gravel. After processing, large impurities such as filter residue are discharged from the screenings outlet 401 at the bottom of the pretreatment group 4, while the organic-inorganic mixture containing sand and gravel and organic mud enters the vibrating sorting group 2 through the pipe from the organic-inorganic material outlet 402 on the lower side of the pretreatment group 4.

[0018] Vibration sorting group 2 adopts an inclined vibration sorting disc structure. After materials containing sand and gravel and organic slurry enter the vibration sorting disc, the materials are accurately sorted by adjusting the vibration frequency and vibration amplitude of the sorting disc. Inorganic materials such as sand and gravel are used as oversize materials and enter the inorganic material collection box 102 in gravity separation group 1 through a pipe from the top of vibration sorting group 2. Organic slurry mixture and fine inorganic materials are used as undersize materials and enter the organic material collection box 101 in gravity separation group 1 through a pipe from the bottom of vibration sorting group 2. Vibration sorting group 2 is higher than organic material collection box 101 and inorganic material collection box 102.

[0019] The gravity separation group 1 includes an organic material collection box 101 and an inorganic material collection box 102. The organic material collection box 101 is fixedly connected to the lower part of the vibration separation group 2 through a pipe and is used to collect the organic sludge and mixed liquid separated by the vibration separation group 2. These materials are rich in effective carbon sources and effective biochemical bacteria, and will be returned to the original process section as effective resources of the sewage treatment plant. The inorganic material collection box 102 is fixedly connected to the upper part of the vibration separation group 2 through a pipe and collects inorganic materials such as sand and gravel separated by the vibration separation group 2. These inorganic materials are then transported to the tank 501 of the washing separation group 5 through a pipe. The inorganic material collection box 102 is higher than the tank 501.

[0020] A stirring motor 502 is fixedly installed on the top of the tank 501 of the washing and separation unit 5. A stirring rod is rotatably mounted inside the tank 501, and stirring blades 503 are fixedly installed outside the stirring rod. The output shaft of the stirring motor 502 is fixedly connected to the stirring rod. When inorganic materials such as sand and gravel enter the tank 501 from the inorganic material collection box 102 through a pipe, the stirring motor 502 starts, driving the stirring rod and stirring blades 503 to rotate, stirring the inorganic materials such as sand and gravel inside the tank 501. Simultaneously, a certain amount of water is injected into the tank 501 through a connecting pipe fixedly connected to a water supply pipe on one side of the tank 501. Utilizing the wall adhesion effect and a combination of mixing and stirring, the sand and gravel are efficiently scrubbed, further cleaning the small amount of organic matter coated on the surface of the sand and gravel. After stirring for a period of time, the stirring motor... When 502 stops working, the washed inorganic matter settles to the bottom of tank 501 using the principle of gravity sedimentation. The wastewater generated during washing is discharged to a biological treatment tank through a pipe for further treatment. A conveying pipe 504 is fixedly connected to the bottom of tank 501. A conveying motor 505 is fixedly installed at the top of conveying pipe 504. A conveying rod is rotatably installed inside conveying pipe 504, and a spiral auger is fixedly installed outside the conveying rod. The output shaft of conveying motor 505 is fixedly connected to the conveying rod. When it is necessary to discharge the washed inorganic matter, conveying motor 505 is started. The output shaft of conveying motor 505 drives the conveying rod and spiral auger to rotate, conveying the inorganic matter that has settled to the bottom of tank 501 upward in conveying pipe 504, and finally discharged from the bottom outlet at the top of conveying pipe 504.

[0021] This application can be used in the field of organic-inorganic directional sorting of sediment materials in wastewater treatment plants, and can also be used in other fields applicable to this application. Example

A garbage bin 7 is placed directly below the screenings discharge outlet 401, and the discharged filter residue falls directly into the garbage bin 7. A garbage bin 7 is also placed directly below the discharge outlet, and the discharged inorganic matter falls into the garbage bin 7. The materials collected by the garbage bin 7 can be reused as building materials and other resources.
