Description

Technical Field

[0001] The utility model relates to the field of sludge disposal, in particular to a sludge disposal system integrating filter pressing and drying functions. Background Art

[0002] With the continuous improvement of people's living standards, people have more and more demands for electromechanical equipment in their daily lives. From transportation to various household appliances, computers, printers, etc., they have become indispensable electromechanical products in people's lives. Advanced electromechanical equipment can not only greatly improve labor productivity, reduce labor intensity, improve the production environment, and complete work that cannot be completed by manpower, but the electromechanical equipment mounting bases on the market can only be installed and fixed at a certain height, and cannot be freely raised or lowered, and cannot meet the needs of use in environments at different heights. Even when short-distance height adjustment is possible, the four supporting legs need to be adjusted one by one to achieve height adjustment. Under such operation, the height adjustment process is cumbersome and the work efficiency is low.

[0003] For example, the utility model disclosed in the publication (announcement) number CN220166048U discloses a high-pressure belt-type continuous sludge deep dehydration integrated machine, which includes a conditioning module, a dehydration module and a multi-stage filter press module in sequence. The conditioning module stirs the material evenly and transports it to the dehydration module. The multi-stage filter press modules connected to the rear of the dehydration module are connected to each other and perform multi-stage filtration on the material in sequence. The pressure of the rear filter press module is greater than that of the front filter press module.

[0004] The equipment of the above-mentioned utility model is provided with a conditioning module, a dehydration module and a multi-stage filter press module for sludge treatment, wherein the conditioning module stirs the sludge to make it more uniform, thereby being more conducive to the subsequent dehydration and filter press treatment process. However, during the continuous use of the equipment, a large amount of sewage remains in the conditioning tank along with the sludge feed. Under long-term working conditions, the sewage that is not discharged with the sludge remains in the conditioning tank, which will cause the subsequent conditioning process after the sludge enters, and increase the water content of the subsequent sludge after entering. At the same time, the above-mentioned equipment does not dry the sludge during the sludge filter press process. Utility Model Content

[0005] The purpose of the utility model is to provide a sludge disposal system integrating filter pressing and drying functions to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sludge disposal system integrating filter pressing and drying functions, comprising a conditioning tank connected to a dehydration unit at one end, a cover plate fixedly connected to the center position of the top of the conditioning tank, and a motor fixedly installed at the center position of the top of the cover plate, the output end of the motor is rotatably arranged through the center position of the cover plate and extends to the interior of the conditioning tank, and the output end of the motor is fixedly connected to one end of the rotating shaft through a coupling, and a number of stirring rods are symmetrically connected to both sides of the rotating shaft, a hot air blower is fixedly installed on the top of the cover plate, and the output end of the hot air blower is connected to the interior of the conditioning tank through a pipeline, an air pump is fixedly installed on the side of the top of the cover plate away from the hot air blower, and one end of the air pump is connected to the interior of the conditioning tank through a pipeline, the other end of the air pump is connected to one end of the drying component through a pipeline, and the bottom end of the drying component is fitted with the cover plate.

[0009] Preferably, both ends of the connecting pipe are connected to the interior of the air jet pipe respectively, and the top end of the connecting pipe is connected to one end of the motor through a pipeline.

[0010] Preferably, a plurality of nozzles are fixedly mounted on one side of the air jet pipe close to the dehydration unit.

[0011] Preferably, the plurality of nozzles are distributed in a ring shape along the bottom end of the air injection pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model starts the motor so that its output end drives the rotating shaft to rotate, thereby evenly stirring the sludge entering the conditioning tank through the feed pipe, heats the outside air through the working state of the hot air blower and then transports it to the inside of the conditioning tank, thereby promoting the drying process of the residual moisture in the conditioning tank, and transports the air containing waste heat in the conditioning tank to the connecting pipe through the working process of the air pump, and is transported through the connecting pipe and sprayed out through multiple nozzles at the bottom end of the jet pipe to dry the sludge dehydrated by the dehydration unit, thereby further improving the sludge treatment effect, and by setting the jet pipe as a ring structure and arranging multiple nozzles in a ring at the bottom end of the jet pipe, the hot air spraying range is expanded, so that the sludge can be in contact with the hot air over a larger area, thereby improving the drying effect.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The output end of the motor 3 is rotatably arranged with the center position of the cover plate 2 and extends to the interior of the conditioning tank 1, and the output end of the motor 3 is fixedly connected to one end of the rotating shaft 4 through a coupling. A plurality of stirring rods 5 are symmetrically connected on both sides. A hot air blower 6 is fixedly installed on the top of the cover plate 2, and the output end of the hot air blower 6 is connected to the interior of the conditioning tank 1 through a pipeline. An air pump 7 is fixedly installed on the top of the cover plate 2 away from the hot air blower 6. One end of the air pump 7 is connected to the interior of the conditioning tank 1 through a pipeline, and the other end of the air pump 7 is connected to one end of a drying component 8 through a pipeline. The bottom end of the drying component 8 is fitted with the cover plate 2. The dehydration unit 200 and the filter press unit have been fully disclosed in the prior art and will not be described in detail here.

[0020] In this embodiment, the drying component 8 includes an air jet tube 81 that is fitted with the dehydration unit 200.

[0021] Furthermore, by starting the motor 3, its output end drives the rotating shaft 4 to rotate, so that the sludge entering the conditioning tank 1 through the feed pipe 9 is evenly stirred, and the outside air is heated by the hot air blower 6 and then transported to the conditioning tank 1 to promote the drying process of the residual moisture in the conditioning tank 1. The air containing residual heat in the conditioning tank 1 is transported to the connecting pipe 82 through the working process of the air pump 7, and is transported through the connecting pipe 82 to be sprayed out through the multiple nozzles 83 at the bottom end of the jet pipe 81 to dry the sludge dehydrated by the dehydration unit 200, thereby further improving the sludge treatment effect. By setting the jet pipe 81 as a ring structure and arranging multiple nozzles 83 in a ring at the bottom end of the jet pipe 81, the hot air ejection range is expanded, so that the sludge can be in contact with the hot air over a larger area, thereby improving the drying effect.
