Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage treatment device. Background Art

[0002] Wastewater treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering, and is increasingly entering the daily lives of ordinary people.

[0003] Compared with the actual use process, the existing sewage treatment devices currently use a multi-layer filter to filter sewage, so as to filter out harmful substances such as heavy metals and plastics in the sewage and prevent them from entering the outside world, thereby avoiding sewage discharge from causing pollution to the outside world. Although this filtering method can improve the filtering efficiency of sewage, the service life of the filter is limited, and frequent replacement of the filter will increase the investment in production costs.

[0004] Therefore, in order to solve the above problems, the present application provides a sewage treatment device.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By installing a stirring seat tube at the bottom of the centrifugal tank, the centrifugal force is used to stir the sewage inside the centrifugal tank. During this period, the impurities in the sewage will be in the middle of the sewage due to their own gravity, and finally enter the mud storage tank through the hole in the middle of the stirring seat tube.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 4A sewage treatment device comprises a support frame 1, a centrifugal tank 2 is fixed to the inner side of the top of the support frame 1 by bolts, a transmission chamber 3 is provided at the inner bottom of the centrifugal tank 2, a stirring seat tube 4 is embedded at the inner bottom of the centrifugal tank 2, in order to stir the sewage inside the centrifugal tank 2, thereby forming a centrifugal effect to separate impurities in the sewage, a rotating motor 5 is installed on the inner side of the transmission chamber 3 through a base, a driving bevel gear 6 is connected to the driving end of the rotating motor 5, a driven bevel gear disc 7 is welded to the outer side of the bottom end of the stirring seat tube 4, a mud storage tank 8 is fixed to the inner side of the bottom end of the support frame 1 by bolts, in order to store sludge and impurities, a connecting pipe 9 is connected to one side of the top of the mud storage tank 8, and the other end of the connecting pipe 9 is connected to the top of one side of the centrifugal tank 2, and the stirring seat tube The discharge end penetrates the centrifugal tank 2 and is connected to the top of the mud storage tank 8. A sludge discharge pipe 10 is connected to one end of the mud storage tank 8. In order to facilitate the discharge of sludge, a screw 12 is embedded at one end of the inner side of the mud storage tank 8. A discharge motor 11 is installed on the outer side of one end of the sludge discharge pipe 10 through the base. The driving end of the discharge motor 11 penetrates the sludge discharge pipe 10 and is connected to one end of the screw 12. A discharge port 13 is opened at the bottom of the sludge discharge pipe 10. A sewage pool 16 is placed on the outer side of one end of the centrifugal tank 2. In order to store sewage, a water pump 14 is installed on the top of the centrifugal tank 2 through the base. The water outlet end of the water pump 14 extends through the inner side of the centrifugal tank 2. The water inlet end of the water pump 14 is connected to a delivery pipe 15. The water inlet end of the delivery pipe 15 extends to the inner side of the sewage pool 16.

[0023] Working principle: First, the operator starts the water pump 14, and then the water pump 14 will pump water into the sewage pool 16 through the delivery pipe 15 connected to its water inlet end, and the sewage will enter the centrifugal tank 2 through the water outlet end of the water pump 14. The sewage entering the centrifugal tank 2 will flow into the mud storage tank 8 through the hole in the middle of the stirring seat tube 4 embedded in the inner bottom end thereof. After the sewage inside the centrifugal tank 2 and the mud storage tank 8 is filled to a certain extent, the water pump 14 is turned off, and then the rotating motor 5 installed in the transmission bin 3 opened at the inner bottom end of the centrifugal tank 2 is started. At that time, the rotating motor 5 will drive the active bevel gear 6 connected to its transmission end to rotate, and the active bevel gear 6 will drive the driven bevel gear disc 7 meshing on the outside to rotate, and the driven bevel gear disc 7 will drive the stirring seat tube 4 welded on the inner side to rotate, and the stirring seat tube 4 will rotate at the inner bottom end of the centrifugal tank 2, and at the same time, its bottom end will also rotate through the bearing connected to the mud storage tank 8;

[0024] As the stirring seat tube 4 rotates, the sewage inside the centrifugal tank 2 will be stirred to form a vortex, and the impurities in the sewage will all gather at the bottom of the vortex due to their own gravity, and enter the mud tank 8 along with a small amount of water. Since the sewage inside the mud tank 8 is full, the impurities will sink to the bottom of the inside after entering, and as the impurities continue to enter, the water inside the mud tank 8 will be squeezed into the centrifugal tank 2 by the impurities through the connecting pipe 9 until the impurities inside the mud tank 8 are stored to a certain extent, then the rotating motor 5 is turned off, and then the drainage valve connected to one end of the mud tank 8 is opened. The pipe will be opened, and the water inside the centrifugal tank 2 and the sludge storage tank 8 will be discharged. After the sewage is discharged, the discharge motor 11 will be started, and the discharge motor 11 will drive the screw 12 connected to the transmission end to rotate. During this period, the operator will remove the clamping plate fixed by bolts at the bottom of the sludge discharge pipe 10. As the screw 12 rotates, the sludge inside the sludge storage tank 8 will be carried by the screw 12 and discharged to the discharge port of the sludge discharge pipe 10. This design can avoid the cost increase caused by the intervention of the filter screen, and can also avoid the reduction of filtration efficiency caused by clogging of the filter screen due to long-term use.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
