Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, in particular to a screw stacking type sludge dewatering treatment device. Background Art

[0002] The generation of sludge is inevitable in modern industrial and municipal wastewater treatment processes. This sludge contains a high percentage of water, and direct discharge or disposal not only takes up a significant amount of space but also causes significant environmental pollution. Therefore, effective sludge dewatering has become a crucial component of environmental protection and resource recovery. Traditional sludge dewatering methods include natural sedimentation, vacuum filtration, and centrifugal separation, but these methods often suffer from low efficiency, high energy consumption, and unsatisfactory dewatering results.

[0003] In the existing spiral stack sludge treatment device, it is not easy to control the amount of added chemicals when adding chemicals, resulting in the possibility that underutilized chemicals may enter the environment with wastewater discharge, causing pollution to water bodies and soil. Utility Model Content

[0004] The purpose of the utility model is to provide a spiral stacking sludge dewatering treatment device to solve the above-mentioned technical problems, so as to achieve the effect of quantitatively adding chemicals.

[0005] In view of this, the present invention provides a spiral stacking sludge dewatering treatment device, comprising:

[0006] A flocculation box, wherein a support frame is provided at the bottom of the flocculation box, a feed trough is protruding from the side of the flocculation box, and a feed pipe is provided at the bottom of the feed trough;

[0007] A partition, the partition is vertically arranged in the feed trough, and an overflow trough is opened on the top of the partition;

[0008] A communication trough, which is provided on the side wall of the flocculation tank and is located between the feed trough and the flocculation tank;

[0009] A quantitative feeding structure is provided on the top of the flocculation tank for quantitatively feeding the reagent;

[0010] A stirring structure, which is arranged in the flocculation tank and connected to the quantitative feeding structure;

[0011] A connecting pipe is provided between the dehydrator body and the flocculation box.

[0012] In this technical solution, sewage is discharged into a feed trough through a feed pipe and into a flocculation tank through the coordination between an overflow trough and a connecting trough. A stirring structure and a quantitative feeding structure are provided to allow a quantitative amount of reagent to be added to the flocculation tank for reaction with the sludge. The sewage in the flocculation tank is then transported to the dewatering machine through a connecting pipe for dewatering. The quantitative feeding structure controls the dosage of the device, preventing excessive dosage of reagent, which could result in underutilized reagent entering the environment along with wastewater discharge, potentially polluting water and soil.

[0013] In the above technical solution, further, the quantitative feeding structure includes:

[0014] A mounting plate, the mounting plate being arranged on the top of the flocculation tank, and a medicine hopper being arranged on the top surface of the mounting plate, and a support column being arranged between the medicine hopper and the mounting plate;

[0015] The delivery pipe is horizontally arranged above the mounting plate, and the delivery pipes are staggered on the delivery pipe, one of which is connected to the bottom of the medicine hopper;

[0016] A spiral blade is rotatably disposed in the conveying pipe and cooperates with the stirring structure to drive the spiral blade to rotate in the conveying pipe;

[0017] Among them, a valve is provided on the material delivery pipe connected to the bottom of the medicine hopper.

[0018] In this technical solution, the rotation of the stirring structure can drive the spiral blade to rotate, so that the medicine in the medicine hopper can be quantitatively put into the flocculation box through the medicine hopper, feed pipe, delivery pipe, and feed pipe in turn, and stirred by the set stirring structure to accelerate the reaction between the medicine and sewage and improve the sludge treatment efficiency.

[0019] In the above technical solution, further, the stirring structure includes:

[0020] A rotating shaft, the rotating shaft being vertically arranged in the flocculation tank, and the stirring blades being symmetrically arranged on the rotating shaft;

[0021] a first motor, wherein the first motor is arranged on the bottom surface of the flocculation box, and an output shaft passes through the bottom surface of the flocculation box and is connected to the rotating shaft;

[0022] A first bevel gear and a second bevel gear, wherein the first bevel gear and the second bevel gear are respectively arranged on the top of the rotating shaft and the end of the spiral blade;

[0023] Wherein, the first bevel gear and the second bevel gear are meshed with each other.

[0024] In this technical solution, starting the first motor to drive the rotating shaft to rotate can drive the stirring blade to rotate, which is beneficial to improving the mixing efficiency between the reagent and the sludge. In addition, the first bevel gear and the second bevel gear are matched to drive the spiral blade to rotate.

[0025] In the above technical solution, further, a cutting blade is rotatably provided at the sludge discharge end of the dehydrator body.

[0026] In this technical solution, the cutting blade is installed on the output shaft of the motor that drives the spiral stack to rotate, and is located at the discharge end of the dewatering machine body. When the dewatering machine body discharges the dehydrated sludge, the rotating cutting blade can cut the sludge, thereby reducing the space occupied by the sludge when receiving the sludge.

[0027] In the above technical solution, further, the spiral blade is away from the medicine hopper side, and the diameter of the central axis of the spiral blade gradually increases.

[0028] In this technical solution, the central axis of the spiral blade with gradually increasing diameter can squeeze the agent when the spiral blade drives the agent forward, causing the agents to squeeze each other, thereby causing the agents to further break up, which is beneficial to improving the reaction efficiency between the agent and the sludge.

[0029] In the above technical solution, further, a cover plate is hingedly provided on the top of the medicine hopper, and a handle is fixedly provided on the top surface of the cover plate.

[0030] In the present technical solution, the cooperation between the hinged cover and the handle can facilitate the operator to lift the cover and add medicine into the medicine hopper.

[0031] In the above technical solution, further, an observation window is vertically provided on the outer wall of the medicine hopper.

[0032] In this technical solution, the observation window provided can facilitate the operator to observe the amount of medicine inside the medicine hopper, which is beneficial to improving the stability of the device.

[0033] The beneficial effects of the utility model are:

[0034] 1. Sewage is discharged into the feed trough through the feed pipe and into the flocculation tank through the coordination between the overflow trough and the connecting trough. A predetermined amount of chemical is added to the flocculation tank through the stirring structure and the quantitative feeding structure, allowing the chemical to react with the sludge. The sewage in the flocculation tank is then transported to the dehydrator through the connecting pipe for dehydration. The quantitative feeding structure controls the dosage of chemical, preventing excessive chemical input, which could result in underutilized chemical entering the environment along with wastewater discharge, causing water and soil pollution.

[0035] 2. By installing the cutting blade on the output shaft of the motor that drives the stacking screw and locating it at the discharge end of the dehydrator body, when the dehydrator body discharges the dehydrated sludge, the rotating cutting blade can cut the sludge, thereby reducing the space occupied by the sludge when receiving the sludge.
