Description

TECHNICAL FIELD

[0001] The utility model belongs to sludge treatment technical field, specifically speaking, a kind of automatic operation platform for dry sludge treatment BACKGROUND

[0002] After purifying treatment, industrial, domestic wastewater produces a lot of sludge with water content 99.7-97%, and after dewatering by conventional sludge dewatering equipment, it is generated as sludge with water content about 80-85%. According to the investigation result, nearly 90% of the sludge produced by wastewater treatment station and sewage treatment plant has not been properly reduced and resourceful. Further drying of sludge is a very feasible method of sludge reduction, and further drying of this kind of pre-dewatered sludge does not produce secondary waste gas pollution, and efficient reduction of energy consumption is a technical problem in the field of environmental protection.

[0003] At present, the sludge drying process equipment widely used at home and abroad is mainly thermal drying technology, including fluidized bed drying, belt drying, horizontal rotary drying, paddle drying, vertical disc drying, spray drying and other process equipment. When considering the maturity of technology and the operation cost of investment, the sludge drying process and equipment need to be selected in combination with the requirements of sludge treatment project; At the same time, the dust, odor emission and other problems generated in the process of sludge drying need to be treated by additional treatment facilities. The existing loading dust removal system adopts unloading screw conveyor plus loading chute device design, basically adopts direct air draft dust removal mode on the loading chute, installs air draft pipeline on the loading chute to the sludge bin, uses the negative pressure formed in the bin when the sludge bin dust remover works to suck the dust generated in loading operation. Due to the design reasons of existing loading dust removal system, negative pressure, flow and other factors, it cannot effectively absorb the impact air flow of falling material, and the effect of suppressing dust is not good

[0004] In addition, the existing sludge drying technology is mostly implemented by single-performance equipment, and there are inevitable dust and odor emission problems during sludge drying. If additional treatment and prevention facilities are not added, it will inevitably cause secondary pollution to the environment.

[0005] In addition, the loading operation process of the desilting chamber is basically manually operated by the driver (vehicle) in cooperation with the on-site operator. One-time loading operation requires two on-site operators to cooperate and operate. The on-site operator is responsible for guiding the vehicle to the right position, and at the same time, the on-site operator climbs to the top of the dump truck through the mobile ladder, and operates the unloading chute to align with one of the loading ports of the dump truck. During the loading process, the on-site operator needs to observe the loading condition of the loading port at any time, and timely manually controls the flatness of the tank car into the loading port with tools to prevent the dry sludge from being pushed into the unloading chute due to the accumulation of dry sludge, causing unsmooth unloading or even overflow outside the vehicle. When the on-site operator judges that the loading port is full, the driver and the vehicle need to repeat the previous operation twice until the whole vehicle is full, and the loading operation is completed. The dry sludge in the silo occasionally forms a lump, which has caused the unloading chute and the unloading screw to be blocked, and the equipment needs to be cut, the cleaning port needs to be opened, and the blockage needs to be manually cleared. After the cleaning port is welded and repaired, the operation can be restored. The overall processing process is complicated, resulting in low efficiency. Practical new type content

[0054] In specific use:

[0055] The total control console issues a loading instruction, the driver drives the sludge unloading car to stop behind the sludge car conveying mechanism, and the sludge car conveying mechanism moves the sludge unloading car to below the sludge bin.

[0056] It is detected whether the inlet of the sludge unloading car is aligned with the discharge port of one of the automatic sludge unloading devices, i.e., the inlet is connected with the screening crusher at the discharge port, and if it is already aligned, the dust removal device is controlled to seal the other inlets on the sludge unloading car.

[0057] The gate valve is opened, the sludge in the sludge bin enters the screening crusher through the discharge port, and then enters the sludge unloading car through the inlet after being crushed, and in this process, the dust removal device is used to suck away the dust at the other inlets in the sludge unloading car, and the suction force of the dust removal device is set to a relatively constant range, so that the sludge inside is not sucked away, but the dust is ensured to be sucked away.
