Description

Technical Field

[0001] The present application relates to the field of sewage treatment equipment, specifically a sewage treatment microfiltration machine. Background Art

[0002] Wastewater treatment is a process of purifying sewage to ensure that it meets the water quality requirements for discharge into a certain water body or reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. Among the treatment methods, microfiltration machines are sometimes used. Microfiltration machines can be used to filter raw water in water plants and remove plankton such as algae and water fleas. They can also be used for filtering industrial water, recovering swimming substances in industrial wastewater, and final treatment of sewage.

[0003] Application No. 202111572758.9 discloses a sewage treatment microfiltration machine, which includes a mounting plate, a support seat, a protective cover, a filtering device, a flushing device and a discharge port to collaboratively complete the filtration treatment of sewage. It can solve the problem that when the existing microfiltration machine treats sewage, the sewage to be treated is directly transported into the sewage treatment microfiltration machine for filtration treatment, solving the problems that a single filtration is difficult to fully remove impurities in the sewage and the existing microfiltration machine wastes a large amount of clean water when discharging impurities.

[0004] However, in actual use, the following problems may occur:

[0005] Since the device uses spiral bars to transport the impurities in the filter frame to the discharge port, and then manually removes and collects the filtered impurities from the discharge port, when the sewage is seriously polluted, it is too late to clean the filter frame by simply separating the impurities. Over time, impurities will accumulate, affecting the subsequent filtering effect. Utility Model Content

[0006] The purpose of this application is to provide a sewage treatment microfiltration machine, which solves the problem raised in the background technology that since the device uses spiral bars to transport impurities in the filter frame to the discharge port, and then manually removes and collects the filtered impurities from the discharge port, when the sewage is seriously polluted, it is too late to clean the filter frame by simply separating the impurities, and impurities will accumulate over time, affecting the subsequent filtering effect.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a sewage treatment microfiltration machine, comprising a base plate, an outer shell, an outer filter, an inner filter and a drainage hole, wherein a motor is movably installed at the bottom of the base plate, a rotating shaft is fixedly installed at the center of the top of the base plate, the top of the base plate is fixedly connected to the outer shell, the top of the outer shell is fixedly connected to the top plate, the top of the rotating shaft is movably connected to the support plate, the outer filter is fixedly connected to the outer filter on the outside of the top of the support plate, the inner support plate is movably connected to the inner filter on the inside of the top of the support plate, the inner filter is fixedly connected to the top of the inner filter, the inner fixed plate is fixedly connected to the top of the outer filter, the outer fixed plate is fixedly connected to the top of the outer filter, the outer fixed plate is fixedly connected to the top of the outer filter, a large circular hole is opened in the center of the top of the outer fixed plate, and the inner fixed plate is located inside the large circular hole of the outer fixed plate.

[0008] In this technical solution, impurities in the device can be quickly cleaned through the connecting block, inner fixing plate, outer fixing plate, inner filter and outer filter. By pulling out the inner filter and outer filter for replacement, the impurities in the device can be quickly cleaned, and the inner filter or outer filter can be pulled out separately without affecting the normal filtering work of the device. After the filter is replaced, it can be inserted into the large circular hole of the outer fixing plate and then connected to the connecting block. This not only increases the filtering efficiency, but also improves practicality.

[0009] As an optional solution to the technical solution of this application, a water inlet hole is opened at the top of the inner fixed plate, a connecting block is movably connected to the top of the inner fixed plate, a water inlet pipe is connected to the top of the connecting block, and a valve is fixedly connected to the side wall of the water inlet pipe.

[0010] As an optional solution of the technical solution of the present application, the center of the top end of the top plate is movably connected to the external fixing plate.

[0011] As an optional solution of the technical solution of the present application, drainage holes are provided on both sides of the top of the bottom plate.

[0012] As an optional solution of the technical solution of the present application, a handle is fixedly connected to the left side of the top end of the outer fixing plate and the inner fixing plate.

[0013] As an optional solution of the technical solution of the present application, the motor shaft of the motor is connected to the rotating shaft.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The present application uses the connecting block, inner fixing plate, outer fixing plate, inner filter and outer filter to quickly clean impurities in the device. By pulling out the inner filter and the outer filter for replacement, the impurities in the device can be quickly cleaned. The inner filter or the outer filter can be pulled out separately without affecting the normal filtering work of the device. After the filter is replaced, it can be inserted into the large circular hole of the outer fixing plate and then connected to the connecting block. This not only increases the filtering efficiency but also improves practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0021] like Figure 1 As shown, a sewage treatment microfiltration machine includes a bottom plate 9, an outer shell 101, an outer filter screen 202, an inner filter screen 302 and a drainage hole 5. The top of the bottom plate 9 is fixedly connected to the outer shell 101, the top of the outer shell 101 is fixedly connected to the top plate 1, and the top of the rotating shaft 4 is movably connected to the support plate 204.

[0027] In actual use, the valve 701 is opened, sewage is transported into the device through the water inlet pipe 7, the motor 10 is started, and the shaft 4 drives the support plate 204 and the inner support plate 303 to rotate. The inner filter 302 and the outer filter 202 throw out the sewage during the rotation, while retaining impurities in the net. The impurities in the device can be quickly cleaned through the connecting block 6, the inner fixing plate 3, the outer fixing plate 2, the inner filter 302 and the outer filter 202. By pulling out the inner filter 302 and the outer filter 202 for replacement, the impurities in the device are quickly cleaned.

After holding the handle 8, the inner filter 302 or the outer filter 202 can be selected to be pulled out separately, so as not to affect the normal filtering work of the device. After the inner filter 302 or the outer filter 202 is replaced, it is inserted back into the device and then connected to the connecting block 6 and the valve 701 is opened. This not only increases the filtration efficiency but also improves the practicality.
