Description

Technical Field

[0001] This application relates to the field of sludge treatment technology, and in particular to an integrated sludge directional composting treatment device. Background Technology

[0002] With increasingly stringent environmental regulations, the effective treatment of sewage sludge has become a pressing issue. Directional sludge composting, as an important sludge treatment method, has attracted widespread attention due to its advantage of converting sludge into fertilizer and realizing waste utilization. The main purpose of directional sludge composting equipment is to transform the organic matter in the sludge into stable humus through a series of biological and chemical reactions, thereby producing valuable fertilizer. During this process, various substances remain inside the equipment, including incompletely composted sludge, microbial metabolic products, and some impurities. Therefore, regular cleaning of the equipment is a crucial step in ensuring its normal operation and composting effectiveness.

[0003] However, existing sludge directional composting treatment equipment suffers from serious deficiencies in the cleaning process, significantly impacting its ease of use. The biggest problem with cleaning these devices is their considerable depth. While this design feature is beneficial to the sludge composting process to some extent, providing sufficient space and a stable environment, it also creates significant difficulties for cleaning. Due to the depth, operators struggle to directly reach the sludge at the bottom and in the corners. Traditional cleaning tools, such as brooms and shovels, are inadequate in this situation. Thorough cleaning remains difficult in narrow corners and deep within the sludge. This results in some sludge remaining inside the device for extended periods, not only occupying valuable space but also potentially breeding harmful microorganisms and affecting subsequent composting results. Furthermore, the depth of the device inefficients cleaning, requiring significant time and effort from personnel to remove the sludge. Limited operating space also restricts the use of cleaning tools, further slowing down the cleaning process. This not only affects the normal operation of the equipment but also increases operating costs. Therefore, in order to improve the practicality and efficiency of the device, it is necessary to improve the structure and cleaning method of the device and develop a sludge directional composting treatment device that is easier to clean. Summary of the Invention

[0004] One of the purposes of this application is to provide an integrated sludge directional composting treatment device, which aims to solve the problem of low efficiency in existing sludge directional composting treatment.

A self-cleaning mechanism is installed on the tank cover. The self-cleaning mechanism includes a mounting bracket connected to the upper end of the bucket lid. A motor is fixedly connected to the upper end of the mounting bracket, and an electric actuator is fixedly connected to the output end of the motor.

[0013] As one technical solution of this application, the scraper is provided with a plurality of drainage holes evenly distributed.

[0014] As one technical solution of this application, the end of the water inlet pipe away from the water pump is connected to a flange.

Therefore, this device, through the cooperation of the scraper and high-pressure nozzles, can quickly and effectively clean the interior of the sludge composting treatment device, significantly improving the convenience of directional sludge composting treatment and use, and greatly increasing its working efficiency.
