Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and relates to a municipal sewage pipeline device and method with a microorganism delivery function. Background Art

[0002] Microbial placement in municipal underground pipelines usually refers to the introduction of specific microbial flora for specific purposes in environments such as sewage treatment facilities or integrated pipelines. Microorganisms can decompose organic matter in sewage and convert it into harmless substances such as carbon dioxide and water, thereby purifying sewage. By introducing beneficial microorganisms, the odor generated by sewage can be reduced or even eliminated. Microorganisms can accelerate the decomposition of organic waste, reduce sludge generation, and reduce sludge treatment costs. Microbial placement is crucial. The most common microbial placement equipment currently available is a delivery pump; a delivery pump is a device used to place microorganisms in municipal underground pipelines in daily life, and it has been widely used in the field of municipal environmental protection.

[0003] When using the existing delivery pump, an appropriate amount of microbial product is added to the dissolution tank in batches. The quantity of each batch should be controlled at a certain proportion of the volume of the dissolution tank. The delivery pump is turned on, and the valve to the target area is opened through the control system. The high-pressure water gun is continued to be used for flushing and water injection to maintain a moderate proportion of solids in the tank to avoid excessive concentration leading to poor fluidity or clogging of the pump. During the entire process, water quality parameters are closely monitored to ensure that conditions are suitable for the survival of microorganisms. It was found in the use of existing delivery pumps that most delivery pumps are fixed-point delivery, and the pipe body needs to be extended after the manhole cover is opened for delivery, resulting in poor flexibility and poor uniformity of microbial laying, thereby resulting in low working efficiency of the equipment.

[0050] Example 2,

[0051] Microbial delivery,

[0052] S1: When microorganisms need to be placed, the telescopic device is activated to extend and retract to both sides of the placement box, and the equipment is adjusted to an appropriate size through extension and retraction. During this process, the longitudinal adjustment device is activated to slide, and the sliding drives the lateral wheels connected to it to contact the pipeline. During the contact process, the motors on the lateral wheels are activated to drive the lateral wheels to roll, and the rolling provides auxiliary power to the driving device, so that the equipment will not roll over due to top power during the sliding process;

[0053] S2: During this process, the longitudinal adjustment device is activated to expand at an oblique angle, and the inner wall of the pipeline is adaptively supported by the rebound force of the spring after expansion;

[0054] S3: During the driving process of the equipment, the driving device is started to lift and lower, and is adjusted according to the inner diameter of the pipeline so that the output roller fits the inner diameter. After fitting, the first motor is started to rotate, driving the driving wheel to roll and move. During this process, the throwing device is started to extend it into the placement box to release the microorganisms in an orderly manner.

[0055] Example 3,

[0056] device drivers,

[0057] S1: In the process of driving the equipment, the first electric push rod is started to extend and retract. During the extension and retraction process, the support rod hinged to the first electric push rod is pushed to rotate in an arc on the top plate, and the rotation drives the driving plate to move up and down;

[0058] S2: After the driving plate is raised and lowered to a certain height, the spring rebounds to support and fit the driving wheel on the driving plate against the inner wall of the pipe;

[0059] S3: During this process, the first motor is started to drive the driving wheel to rotate, thereby driving the device.

[0060] Example 4,

[0061] displacement,

[0062] S1: Before the device is driven, it is necessary to adjust the device and start the second electric push rod to drive the telescopic arm connected to it to slide. During the sliding process, the sliding position and direction of the telescopic arm are limited and stabilized by the first guide rail;

[0063] S2: During this process, the hydraulic cylinder is started to drive the extension arm to slide, and the second guide rail is used to stabilize the extension arm. After sliding to the appropriate position, the fourth electric push rod is started to drive the extension arm to rotate, forming a triangular structure with the lateral wheel to provide lateral stability support;

[0064] S3: During the displacement of the device, the driving wheel rolls and the lateral wheels rotate to displace the device.

[0065] Example 5,

[0066] Stability and balance,

[0067] S1: When the device moves in the pipeline, a steering problem may occur. The angles on both sides of the device need to be adjusted. During this process, the third electric push rod is activated to drive the tripod to rotate. The tripod's stable structure provides stable support, driving the support arm to rotate, thereby completing the device's steering.

[0068] S2: During this process, after the support arm is reset, the elbow on the support arm is inserted into the slot to assist in stabilization;

[0069] S3: Cooperate with the steel sleeve on the lateral wheel to provide stability and balance for the sliding of the equipment.

[0070] Example 6,

[0071] Restoring the ecology,

[0072] S1: During the process of releasing microorganisms, a motor is provided at the connection between the curved rod and the placement box. The curved rod is started to rotate, driving the bottom plate to rotate and expand in an arc, driving the microorganism dispenser to release the microorganisms;

[0073] S2: The selected microorganisms are mixed into the carrier solution in the recommended proportions. By introducing beneficial microorganisms, the odor generated by the sewage can be reduced or even eliminated.

[0074] S3: Introducing specific microorganisms into polluted surface water or groundwater can help degrade toxic and harmful substances and restore the ecological environment.

[0075] In the above method,

[0076] Microorganisms are delivered through automatic operation, allowing the equipment to automatically slide along the pipeline and deliver the microorganisms in an orderly manner during the sliding process, avoiding the fixed position and uneven delivery of traditional delivery.

[0077] The device automatically expands and contracts to adapt to pipelines of different sizes, thereby providing adjustable performance for the device.

[0078] During the sliding process of the equipment, a steel sleeve is installed to make it slide with more friction, avoiding the situation where the traditional roller has low friction when sliding in the pipeline, resulting in unstable sliding of the equipment.

The method for placing microorganisms into a municipal sewage pipeline device according to any one of claims 1 to 7, wherein: The steps include: S1, when microorganisms need to be placed, the telescopic device is activated to extend and retract to both sides of the placement box, and the device is adjusted to an appropriate size by telescoping; S2, start the longitudinal adjustment device to expand it at an oblique angle, and after expansion, the inner wall of the pipeline is adaptively supported by the rebound force of the spring; S3, during the driving process of the equipment, the driving device is started to lift and lower, and is adjusted according to the inner diameter of the pipeline so that the output roller fits the inner diameter. After fitting, the first motor is started to rotate, driving the driving wheel to roll and move. During this process, the throwing device is started to extend it into the placement box to release the microorganisms in an orderly manner.

9. The method for placing microorganisms into a municipal sewage pipeline device according to claim 8, wherein: In the process of driving the equipment, the first electric push rod is started to extend and retract. During the extension and retraction process, the support rod hinged to it is pushed to make it rotate in an arc on the top plate, and after the rotation, the driving plate is driven to rise and fall. After the driving plate is lifted to a certain height, the spring rebounds to support and fit the driving wheel on the driving plate with the inner wall of the pipeline. In this process, the first motor is started to drive the driving wheel to rotate, so as to drive the equipment.
