Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sewage treatment, and in particular to a backwash device for a slag discharge pipeline. Background Art
[0002] The screw conveying equipment for sewage treatment is used to transport the oil residue, scum, sediment and other residues produced after sewage treatment to the scum pool through the scum discharge pipeline. At present, the impurities in the sewage are sent to the scum discharge pipeline through the screw conveying mechanism, and then the impurity mixture is discharged to the scum pool by self-flow. However, the mixture is relatively thick and has poor fluidity in the scum discharge pipeline. The equipment is prone to blockage of the scum discharge pipeline during operation, requiring frequent repairs.
[0003] At present, when repairing the slag discharge pipeline, it is usually necessary to disconnect the flange connecting the slag discharge pipeline to the spiral conveying mechanism in order to clean the inside of the slag discharge pipeline; however, this method can easily cause the impurity mixture to flow from the flange mouth to the ground, causing pollution to the equipment platform and surrounding areas and polluting the air, which invisibly increases the risk level of safe operation. Utility Model Content
[0004] In order to facilitate cleaning of the interior of a slag discharge pipeline, the present application provides a recoil device for the slag discharge pipeline.
[0005] The present application provides a recoil device for a slag discharge pipeline adopting the following technical solution:
[0006] A recoil device for a slag discharge pipeline comprises a recoil pipe and a recoil nozzle, wherein the recoil pipe is connected to the slag discharge pipeline, and the recoil nozzle is installed on the recoil pipe and located at one end of the recoil pipe away from the slag discharge pipeline; the recoil pipe is provided with a plugging assembly, and the plugging assembly is used to separate the recoil pipe and the slag discharge pipeline.
[0007] By adopting the above-mentioned technical scheme, when the slag discharge pipeline is blocked, the sealing component is closed to connect the recoil pipe with the slag discharge pipeline; at this time, the recoil pipe is used as a channel to guide the water flushed out of the recoil nozzle into the slag discharge pipeline, and can dilute the impurity mixture in the slag discharge pipeline, and form a pressure difference between the beginning and the end of the slag discharge pipeline, thereby driving the mixture in the slag discharge pipeline to flow, thereby clearing the blockage in the slag discharge pipeline and maintaining the smooth flow of impurities in the slag discharge pipeline.
[0008] Optionally, the blocking assembly includes a mounting ring and a plurality of sector plates, the mounting ring being mounted on the inner wall of the recoil tube, and all the sector plates being hinged to the mounting ring; a torsion spring is arranged between the sector plate and the mounting ring, and the elastic force of the torsion spring drives all the sector plates to retract toward each other.
[0009] By adopting the above-mentioned technical solution, under normal circumstances, the elastic force of the torsion spring can make all the fan-shaped plates retract against each other to form a complete sealing surface, thereby isolating the connection between the recoil pipe and the slag discharge pipeline, preventing the mixture in the slag discharge pipeline from entering the recoil pipe, thereby reducing the situation where the recoil nozzle is immersed in the mixture.
[0010] When the slag discharge pipeline needs to be recoiled and cleaned, the recoil nozzle sprays water. At this time, one side of the fan plate is impacted by the water, causing the elastic force of the torsion spring to expand outward, so that high-pressure flushing water is sprayed into the slag discharge pipeline for cleaning. After the cleaning is completed, the fan plates are retracted under the elastic force of the torsion spring, and the connection between the recoil pipe and the slag discharge pipeline is cut off again.
[0011] Optionally, a clamping ring is provided on one side of the mounting plate close to the recoil nozzle, and the elastic force of the torsion spring drives the sector plate to abut against the clamping ring under normal conditions.
[0012] By adopting the above-mentioned technical solution and setting a clamping ring, if the mixture in the slag discharge pipeline overflows into the recoil pipe and abuts against one side of the fan-shaped plate, the setting of the clamping ring can reduce the rotation of the fan-shaped plate along the hinge of its own hinge ring toward the side of the recoil nozzle, thereby maintaining the sealing of the separation between the slag discharge pipeline and the recoil pipe.
[0013] Optionally, a rubber layer is provided between two adjacent sector plates.
[0014] By adopting the above technical solution and arranging the rubber layer, the sealing performance of the separation between the slag discharge pipeline and the recoil pipe is further improved.
[0015] Optionally, one end of the recoil pipe away from the slag discharge pipeline is inclined upward, and a sensor is provided in the recoil pipe. The sensor is located on the side of the plugging component close to the slag discharge pipeline; the recoil pipe is provided with an alarm, and the alarm is electrically connected to the sensor.
[0016] By adopting the above-mentioned technical solution and setting the recoil pipe at an angle, it is possible to reduce the situation where the mixture enters the recoil pipe during the process of transporting the mixture through the slag discharge pipeline under normal conditions; and if the slag discharge pipeline is blocked, the mixture enters the recoil pipe. At this time, the sensor senses the mixture and transmits it to the alarm, so as to promptly notify the staff to clear the slag discharge pipeline.
[0017] Optionally, the blocking assembly includes a blocking plate and a cylinder, the recoil pipe is provided with a blocking opening; the blocking plate is passed through the blocking opening to abut against the inner wall of the recoil pipe; the cylinder is installed in the recoil pipe, and the movable plug of the cylinder is connected to the blocking plate.
[0018] By adopting the above technical solution and controlling the movable plug of the cylinder, the abutment between the blocking plate and the inner wall of the recoil pipe can be cancelled, so that the recoil pipe is connected to the slag discharge pipeline and the water of the recoil nozzle is flushed into the slag discharge pipeline.
[0019] Optionally, a sealing groove for plugging a sealing plate is provided on the inner wall of the recoil pipe.
[0020] By adopting the above technical solution, the plugging plate and the plugging groove are plugged together to further improve the sealing performance of the separation between the slag discharge pipeline and the recoil pipe.
[0021] Optionally, the recoil pipe includes a first pipe and a second pipe, the first pipe is connected to the slag discharge pipeline, and the first pipe and the second pipe are connected by bolts; the plugging assembly is installed on the first pipe, and the recoil nozzle is installed on the second pipe.
[0022] By adopting the above technical solution, the recoil pipe is set as the first pipe and the second pipe. When the recoil nozzle is inspected and repaired, it is disassembled through the first pipe and the second pipe. At the same time, the recoil nozzle can be inspected and repaired while the sealing component keeps the slag discharge pipeline isolated, reducing the odor overflow from the slag discharge pipeline.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. By setting a recoil nozzle and a recoil pipe, the recoil pipe is used as a channel to guide the water flushed out of the recoil nozzle into the slag discharge pipeline, and can dilute the impurity mixture in the slag discharge pipeline, and form a pressure difference between the beginning and the end of the slag discharge pipeline, drive the mixture in the slag discharge pipeline to flow, and then play a role in unblocking the slag discharge pipeline and maintaining the smooth flow of impurities in the slag discharge pipeline;
[0025] 2. By setting up a plugging component, the connection between the recoil pipe and the slag discharge pipeline can be isolated, and the mixture in the slag discharge pipeline can be prevented from entering the recoil pipe, so as to reduce the situation where the recoil nozzle is immersed in the mixture.
