A new type of sludge cleaning and collecting device

Abstract

The invention discloses a novel sludge cleaning and collecting device, which comprises a bottom plate, a base is installed on the upper surface of the bottom plate, the lower surface of the base is connected with the upper surface of the bottom plate, and a strut is installed on the upper surface of the bottom plate. The lower surface of the pole is connected to the upper surface of the bottom plate, the upper surface of the base is equipped with a top plate, the lower surface of the top plate is connected to the upper surface of the base, and slide plates are installed on both sides of the outer wall of the base. This new type of sludge cleaning and collecting device, through the action of the bottom plate, base and triangular plate, through the cooperation between the motor, rollers and chains, the bottom plate fixes the base to provide a good support foundation for the backing plate to support the legs and the box. It provides a good operating environment for the stable operation of the motor, improves the product quality of the new sludge cleaning and collecting device, saves the purchase cost of the user, and avoids the resource waste of the new sludge cleaning and collecting device, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of sludge cleaning, in particular to a novel sludge cleaning and collecting device. Background technique [0002] Sludge refers to the water-containing solid sediment produced in the sewage treatment process. It generally comes from municipal water supply and drainage treatment systems and industrial wastewater treatment systems. Its components are mainly water, volatile substances, ash, pathogens and toxic substances. By the end of 2015, the annual output of dewatered sludge (calculated at a water content of 80%) in my country will exceed 26 million tons. The standard issued by the Ministry of Housing and Urban-Rural Development of China in March 2010 - "Sludge Disposal of Urban Sewage Treatment Plants for Mixed Landfill Mud" requires that the moisture content of the sludge entering the landfill should not exceed 60%, so in order to meet Requirements for sludge landfill and reducing the pressure of sludge l...

Problems solved by technology

The standard issued by the Ministry of Housing and Urban-Rural Development of China in March 2010 - "Sludge Disposal of Urban Sewage Treatment Plants for Mixed Landfill Mud" requires that the moisture content of the sludge entering the landfill should not exceed 60%, so in order to meet Requirements for sludge landfill and reducing the pressure of sludge landfill on land resources, further reducing the volume of sludge, and further dehydrating dewatered sludge (with a moisture content of about 80%) have become a research hotspot. The deep dewatering system for sludge is a sludge deep dewatering system that integrates sludge conditioning, transportation, mixing and crushing, and deep pressing and dewatering. However, due to the large amount of negative charges on the surface of sludge flocs, and the sludge After conditioning, a large number of intracellular substances of microorganisms in the sludge are dissolved, which greatly increases the viscosity of the sludge. Therefore, the sludge mixed and crushed by the mixer is easy to bond together again, which affects the sludge in the belt-type deep dehydration press. The uniformity of the cloth on the machine, if the cloth is uneven, not only affects the deep dewatering effect of the sludge, causes mud running, affects the on-site operating environment, but also is prone to discounts on the filter cloth, which will damage the filter cloth and increase the efficiency of the deep dewatering of the sludge. Operating cost, in the prior art, for example, the invention patent with the application number 201420684068.1 includes the device, the sludge feeding bin body, the sludge spreading shaft, the first sludge crushing shaft, the second sludge crushing shaft, Sludge paving shaft, spiral belt, and scraper. The sludge paving shaft is arranged at the feeding end of the sludge feeding bin body. According to the sludge advancing direction, the first sludge crushing shaft, the second The sludge crushing shaft is arranged sequentially behind the sludge spreading shaft, the sludge flattening shaft is arranged behind the second sludge crushing shaft, the sludge spreading shaft, the first sludge crushing shaft, The outer periphery of the second sludge crushing shaft surrounds the spiral belt respectively, the scraper is arranged radially on the outer periphery of the sludge flattening shaft, and the blade of the scraper is parallel to the center of the sludge flattening shaft Shaft, although the structure of this invention is simple, there are many deficiencies and defects. In the existing equipment, there are defects in the design of the first sludge crushing shaft, the second sludge crushing shaft and the sludge paving shaft, and the first sludge crushing shaft The connection between the shaft and the second sludge crushing shaft is unstable, when in use, when the sludge block moves on the sludge flattening shaft, the sludge block is easy to cause the first sludge crushing shaft and the second sludge crushing shaft The jamming between them will affect the normal operation of the spiral belt, which will easily cause damage to the spiral belt, increase the production cost of the enterprise, reduce the processing efficiency, increase the workload of the maintenance personnel, and make the maintenance personnel prone to work fatigue. Cause waste of resources of the sludge cleaning and collecting device, in view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a new type of sludge cleaning and collecting device to overcome the defects in the prior art
