Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration pretreatment, in particular to a high-efficiency pretreatment device for sludge dehydration filtrate. Background Art

[0002] Currently, silt refers to the sediment at the bottom of rivers, lakes, and ponds, also known as sludge or mud. In nature, silt can be formed by natural sedimentation and chemical precipitation from inorganic wastewater or natural water. This silt typically contains a certain amount of organic matter and toxic substances, and its properties vary depending on the formation conditions and composition. For example, the primary sludge from municipal sewage treatment plants is primarily composed of organic matter, while the product of industrial wastewater sedimentation tanks is mainly inorganic sediment.

[0003] Among them, sludge is a solid sediment produced by the water and sewage treatment process. It is a sludge treatment method that removes water from flowing primary, concentrated or digested sludge and converts it into semi-solid or solid mud blocks. After dehydration, the sludge moisture content can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dewatering equipment.

[0004] In the market, when silt is processed into sludge, the silt is directly introduced into the processing equipment. Due to the high water content inside the silt, it is difficult to quickly shape it when processed into sludge. Therefore, it is necessary to design a new technical solution to solve this problem. The silt can be pre-treated to discharge a large amount of water inside the sludge. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency pretreatment device for sludge dewatering filtrate, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-efficiency pretreatment device for sludge dewatering filtrate, comprising a mounting base, on which three groups of equally spaced mounting slots are provided, each group of the mounting slots being equipped with a dewatering treatment mechanism;

[0007] The dehydration processing mechanism includes a connecting cylinder rotatably installed inside the installation groove, a filter cylinder fixedly installed on the top of the connecting cylinder, a slag discharge pipe rotatably installed inside the connecting cylinder through a bearing, a gear ring fixedly installed on the bottom side of the outer wall of the connecting cylinder, and a gear meshing with the gear ring, and the top of the slag discharge pipe is located on the bottom side of the filter cylinder.

[0008] As an optional solution to the technical solution of the present application, a sewage pipe is fixedly installed on the top of the mounting seat, and three groups of equally spaced sewage outlets are installed on the side walls of the sewage pipe. The three groups of sewage outlets correspond to three groups of filter cartridges respectively. Each group of sewage outlets and slag discharge pipes is equipped with an electromagnetic valve, which can guide the material into the filter cartridge.

[0009] As an optional solution to the technical solution of the present application, three groups of equally spaced motors are fixedly installed on the bottom of the mounting base, and the three groups of motor drive output ends are respectively connected to the three groups of transmission shafts, and the three groups of transmission shafts are respectively fixed to the three groups of gear center axes, which can drive the gears to rotate.

[0010] As an optional solution to the technical solution of the present application, three groups of equidistantly distributed baffles are fixedly installed on the top of the mounting seat, and the three groups of baffles are respectively distributed on the outside of the filter cartridge. The side walls of the three groups of baffles are connected and installed with drainage pipes to prevent sewage from splashing everywhere.

[0011] As an optional solution of the technical solution of the present application, connecting frames are fixedly installed on both sides of the bottom of the mounting seat, and two groups of slag collecting pipes are fixedly installed on the bottom of the connection, so that the sludge can be discharged in a centralized manner.

[0012] As an optional solution of the technical solution of the present application, the slag collecting pipes are connected and installed with three groups of slag discharge pipes, and one end of the slag collecting pipe is connected and installed with a slag extraction pump, which can deliver negative pressure to the slag collecting pipes.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The technical solution of the present application drives the gears of the dehydration treatment mechanism to rotate by driving the corresponding motors. The gear ring engaged with the gear will drive the connecting cylinder in the installation groove to rotate. Since the filter cartridge is fixedly installed on the top of the connecting cylinder, the sewage and sludge inside the filter cartridge can be continuously centrifuged to throw the sewage out from the filter holes of the filter cartridge. When the sewage inside one group of filter cartridges is discharged, the solenoid valves on the corresponding slag discharge pipes will be opened, so that the negative pressure introduced by the slag suction pump is transmitted to the top of the slag discharge pipe, and the dehydrated sludge is continuously discharged from the slag discharge pump, and the three groups of filter cartridges are synchronously centrifuged for dehydration, which greatly improves the sludge dewatering efficiency.

[0015] 2. The technical solution of this application is to fix three groups of equidistantly distributed shields on the top of the mounting seat, and the side walls of the three groups of shields are connected and installed with drainage pipes. When the rotating filter cartridge continuously centrifugally dewaters the sludge, the shield installed on the outside of the filter cartridge can well concentrate the flying sewage, avoid a large amount of sewage splashing everywhere and polluting the working environment, and finally the sewage can be efficiently discharged through the drainage pipe.
