Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sludge dewatering devices, and particularly relates to a sludge dewatering device for water supply and drainage. Background Technique
[0002] A sludge treatment method that removes water from fluid raw, concentrated or digested sludge and converts it into semi-solid or solid sludge blocks. After dewatering, the moisture content of the sludge can be reduced to 55% to 80%, depending on the nature of the sludge and sediment and the efficiency of the dewatering equipment. Further dewatering of the sludge is called sludge drying, and the moisture content of the dried sludge is less than 10%. The dewatering methods mainly include natural drying method, mechanical dewatering method and granulation method. The natural drying method and mechanical dewatering method are applicable to sewage sludge. The granulation method is applicable to the sludge of coagulation precipitation;
[0003] At present, when the existing sludge dewatering device for water supply and drainage dewateres sludge, the separated sewage is usually directly discharged outside the device, resulting in waste of resources, or remains in the device, and the smell of the sewage will cause discomfort to the personnel in the device use area.
[0004] In view of this, we propose a sludge dewatering device for water supply and drainage. Content of the Utility Model

The stabilizing column passes through the internal through hole of the dewatering assembly plate. The output end of the sludge dewatering component is provided with a telescopic transmission end. The end of the telescopic transmission end is fixedly installed with a squeezing dewatering plate. The auxiliary guiding column passes through the internal through hole of the squeezing dewatering plate. The auxiliary guiding column is slidably connected with the squeezing dewatering plate. Both ends of the auxiliary guiding column are installed on the inner side of the dewatering assembly plate. A drainage groove is opened below the squeezing dewatering plate, and a post-treatment component is arranged below the drainage groove.
[0008] As a preferred technical solution, a drying air box is installed at the rear end of the sludge dewatering device main body, and an observation window is opened at the front end of the sludge dewatering device main body.
[0009] As a preferred technical solution, the left output end of the drainage groove is installed with a drainage pipe 1, the right output end of the drainage groove is installed with a drainage pipe 2. A water purification tank is arranged at the output end of the drainage pipe 2. A heater is installed on the left side of the water purification tank, and a connecting end is installed above the heater.
[0010] As a preferred technical solution, a discharge box is installed below the clean water tank, and a water outlet pipe is fixedly installed at the output end of the discharge box.

[0012] As a preferred technical solution, a support base is installed below the support frame.
[0013] As a preferred technical solution, installation pads are installed below the support base.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. When the sludge dewatering device main body is in use, the sludge to be dewatered enters the inside of the sludge dewatering component through the feeding trough opening. After the feeding is completed, the telescopic transmission end is started, and the extrusion dewatering plate is pushed towards the opposite dewatering assembly plate. At the same time, the auxiliary guide post maintains the extrusion direction of the dewatering assembly plate to prevent the dewatering assembly plate from shifting. The dewatering assembly plate continuously extrudes and dehydrates the sludge, and the separated water source enters the lower component through the drainage groove. After the extrusion is completed and reaches the maximum limit, the drying air box can be started to accelerate the evaporation of the remaining water source in the sludge and improve the efficiency of sludge dewatering.
[0016] 2. The present utility model guides the separated sewage into the clean water tank through the first drainage pipe and the second drainage pipe. After the clean water tank precipitates and adheres to the sewage, the heater heats and disinfects the cleaned water source.
