Description

Technical Field

[0001] This utility model relates to the technical field of sludge concentration, and in particular to a sludge concentration device. Background Technology

[0002] Wastewater treatment processes generate wastewater containing a large amount of sludge (solid impurities). This wastewater cannot be discharged directly and its solid components need to be concentrated and separated. The resulting clear water and concentrated sludge can be reused after further treatment. The volume of the concentrated sludge is significantly reduced compared to the original wastewater, thus facilitating subsequent treatment or disposal.

[0003] In existing sludge thickening devices, such as the flocculation sedimentation sludge thickening device for sewage treatment disclosed in utility model patent application number 202420101018.X, the tank body of this utility model is provided with an inner pipe and an overflow pipe. The inner pipe contains a sewage inlet pipe, a chemical dosing pipe, and an air supply pipe. The upper ends of the sewage inlet pipe, the chemical dosing pipe, and the air supply pipe all extend out of the tank body. The lower end of the chemical dosing pipe is closed, and its side wall has multiple drug delivery holes. The sewage inlet pipe and the chemical dosing pipe are both located inside the inner pipe. When sewage enters the tank body through the inner pipe, the chemical dosing pipe can pass through the drug delivery holes on its side wall. The spraying of a flocculant solution allows the flocculant components in the solution to come into full contact with solid impurities in the wastewater passing through the inner pipe, promoting rapid sedimentation of these impurities into sludge. Simultaneously, the air supply pipe, driven by an air pump, introduces air into the wastewater below the tank, agitating the water and further promoting the flocculant's effect on solid particles, accelerating sludge deposition, and improving sludge concentration and sedimentation efficiency. Furthermore, the overflow pipe inside the tank is equipped with a filter screen that continuously filters wastewater, significantly reducing impurities in the water flowing out of the overflow pipe and improving wastewater treatment efficiency.

[0004] However, during the sludge thickening process, the deposited sludge still contains a large amount of water, resulting in poor sludge thickening effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sludge thickening device that, by setting a discharge mechanism and an extrusion mechanism, can perform secondary separation of water in the discharged sludge during the sludge thickening process, thereby improving the sludge thickening effect.

[0006] This utility model provides a sludge thickening device, which includes a material storage mechanism; it also includes an overflow mechanism, a stirring mechanism, an aeration mechanism, a discharge mechanism, and a squeezing mechanism. The overflow mechanism is installed on the material storage mechanism, the stirring mechanism is installed on the material storage mechanism, the aeration mechanism is installed on the material storage mechanism, the discharge mechanism is installed at the lower end of the material storage mechanism, and the squeezing mechanism is installed on the discharge mechanism.

[0007] The material storage mechanism stores materials, the overflow mechanism overflows, the stirring mechanism stirs, the aeration mechanism aerates, the discharge mechanism discharges, and the extrusion mechanism extrudes. Sludge and flocculant are added through the material storage mechanism, mixed by activating the stirring mechanism, aerated by activating the aeration mechanism, and the upper layer of clear water overflows through the overflow mechanism. Sludge is discharged through the discharge mechanism, and the extrusion mechanism simultaneously squeezes out water from the discharged sludge. This allows for secondary separation of water from the discharged sludge during the sludge concentration process, thereby improving the sludge concentration effect.

[0008] Preferably, the material storage mechanism includes a sludge tank, a feed inlet, a chemical inlet, and a partition. The feed inlet is installed at the top of the sludge tank, the chemical inlet is installed at the top of the sludge tank, and the partition is installed inside the sludge tank. Sludge is added through the feed inlet, flocculant is added through the chemical inlet, and the partition separates the coagulated sludge from the clear water.

[0009] Preferably, the overflow mechanism includes an overflow box, a baffle, a filter screen, and a guide pipe. The overflow box is installed on the sludge box, the baffle is installed inside the overflow box, the filter screen is installed inside the overflow box, and the guide pipe is installed at the right end of the overflow box. The upper water is filtered through the filter screen, the overflow is coordinated with the baffle, and the overflow water is discharged through the guide pipe.

[0010] Preferably, the stirring mechanism includes a stirring shaft and a motor. The stirring shaft is rotatably mounted on the sludge tank, and the motor is mounted on the upper end of the sludge tank. The output end of the motor is connected to the input end of the stirring shaft. By turning on the motor, the stirring shaft is driven to rotate and stir the sludge.

[0011] Preferably, the aeration mechanism includes an air pump, an aeration channel, and an air pipe. The air pump is installed at the upper end of the sludge tank, the aeration channel is installed inside the sludge tank, and the output end of the air pump is connected to the aeration channel through the air pipe. By turning on the air pump, air is pumped into the aeration channel through the air pipe, causing the gas in the aeration channel to burst out from the small holes for mixing.

[0012] Preferably, the discharge mechanism includes an auger, a spiral blade shaft, and a second motor. The auger is installed at the lower end of the sludge tank, the spiral blade shaft is rotatably installed inside the auger, and the second motor is installed at the left end of the auger, with the output end of the second motor connected to the input end of the spiral blade shaft. By turning on the second motor to drive the spiral blade shaft, the spiral blade shaft rotates to discharge the sludge.

[0013] Preferably, the extrusion mechanism includes a discharge port, a connecting pipe, a filter plate, and a spring. The discharge port is installed at the front end of the auger, the connecting pipe is installed at the right end of the auger and connects with the guide pipe, and the filter plate is slidably installed inside the auger by the spring. The sludge extrudes the filter plate to discharge excess water through the connecting pipe into the guide pipe, and the sludge is discharged from the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: sludge and flocculant are added through the material storage mechanism, the mixing mechanism is opened for stirring and mixing, the aeration mechanism is opened for aeration, the upper clear water is overflowed through the overflow mechanism, the sludge is discharged through the discharge mechanism, and the water in the discharged sludge is squeezed out by the extrusion mechanism. Thus, during the sludge concentration process, the water in the discharged sludge can be separated a second time, thereby improving the sludge concentration effect. Attached Figure Description
