Technical Field

[0001] The utility model relates to the technical field of sludge drying and processing equipment, in particular to a sludge conditioner vacuum drying device. Background Art

[0002] In the field of sludge treatment, sludge drying is a crucial link. However, traditional sludge dryers often face a technical problem during operation, that is, the dried sludge is easy to clump, which brings many inconveniences to subsequent discharge and treatment.

[0003] Specifically, during the drying process, sludge often forms a relatively compact block structure due to the evaporation of water and the concentration of solids. This agglomeration phenomenon not only greatly reduces the fluidity of the sludge, but also makes the dryer prone to clogging when discharging sludge, affecting the efficiency of the entire treatment process. In addition, the agglomerated sludge is difficult to achieve uniform dispersion in the subsequent utilization or disposal process, further limiting its scope of application.

[0004] In summary, the utility model solves the existing problems by designing a sludge conditioner vacuum drying device. Utility Model Content

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0023] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0024] A sludge conditioner vacuum drying device comprises a sludge pool 1, a stirring device 2 is arranged on one side of the sludge pool 1, a conveying device 3 is arranged on the side of the sludge pool 1 close to the stirring device 2, a dryer 4 is arranged on the side of the conveying device 3 away from the sludge pool 1, a heater 5 is arranged on one side of the dryer 4, a condensing device 6 is arranged on the side of the dryer 4 away from the heater 5, a conveyor belt outlet 7 is arranged on the side of the dryer 4 away from the conveying device 3, a machine housing 8 is arranged on the side of the heater 5 close to the conveyor belt outlet 7, a discharge port 9 is arranged on one side of the machine housing 8, a crushing motor cover 10 is arranged on the side of the machine housing 8 close to the discharge port 9, and a crushing roller 11 is arranged on one side of the crushing motor cover 10.

[0025] Specifically, refer to Figure 3A vertical falling channel is provided between the conveyor belt outlet 7 and the crushing motor cover 10 . After the sludge blocks are discharged through the conveyor belt outlet 7 , they directly fall into the vertical falling channel and then enter the crushing motor cover 10 .

[0026] Furthermore, a plurality of groups of crushing rollers 11 are arranged side by side inside the crushing motor cover 10, and each group of crushing rollers 11 can operate independently to ensure that the sludge blocks that fall into the crushing motor cover 10 are fully and evenly crushed.

[0027] Furthermore, the arrangement and rotation speed of the crushing rollers 11 can be adjusted according to the hardness and humidity of the sludge blocks to meet the treatment requirements of sludge of different properties, thereby improving the crushing efficiency and effect.

[0028] For details, please refer to Figure 2 A collecting hopper is provided under the crushing motor cover 10 to collect the sludge particles crushed by the crushing roller 11 to ensure the continuity and efficiency of the treatment process. The collecting hopper is connected to the discharge port 9 to facilitate the smooth discharge of the crushed sludge particles. The crushing roller 11 is made of special wear-resistant and corrosion-resistant materials, which can operate efficiently for a long time without being easily damaged. In addition, the surface of the crushing roller is specially treated to effectively prevent sludge from sticking and clogging, thereby improving the crushing efficiency.

[0029] The working process of the utility model: a sludge conditioner vacuum drying device designed by the present invention is used. In the sludge drying process, the sludge in the sludge pool 1 is first pre-treated by adding a conditioner to improve its dehydration performance. Subsequently, after being fully mixed by the stirring device 2, the sludge is sent to the conveying device 3 and smoothly transported to the dryer 4. In the dryer 4, the sludge is subjected to the heat energy provided by the heater 5, and the internal moisture begins to evaporate. At the same time, the condensing device 6 effectively collects and discharges the generated water vapor to maintain the stability of the drying environment. After a period of vacuum drying treatment, the moisture of the sludge is greatly removed to form a relatively dry block. When the dried sludge blocks are discharged through the conveyor belt outlet 7, they will fall into the crushing motor cover 10, where the array crushers 11 arranged side by side start to rotate at high speed to crush and pulverize the sludge blocks. The arrangement and rotation speed of the crushing rollers 11 can be adjusted according to the hardness and humidity of the sludge blocks to ensure the best crushing effect. After being crushed by the crushing roller 11, the originally agglomerated sludge is evenly refined to facilitate subsequent utilization or disposal. Finally, the crushed sludge particles enter the discharge port through the collecting bucket and are smoothly discharged from the device, which improves the inconvenience of traditional equipment lacking the ability to crush and dry agglomerated sludge.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
