Description

Technical Field

[0001] This utility model relates to the field of microfiltration technology, and in particular to a rotary microfiltration machine. Background Technology

[0002] Rotary microfiltration machines are solid-liquid separation devices widely used in water treatment, wastewater treatment, and industrial production processes. They are primarily used to remove suspended solid particles from liquids to purify water or recover valuable materials.

[0003] Rotary microfiltration machines remove suspended solid particles from liquids using filter media (usually screens or filter cloths). The core of this equipment is a rotating cylinder or drum containing the filter media. When the liquid to be treated enters the equipment, it passes through the filter media under pressure difference, while solid particles are trapped on the surface of the filter media, forming a filter cake. Traditional rotary microfiltration machines typically require an external power source such as a motor to drive the drum rotation, consuming additional energy. Filtered impurities tend to adhere to the inside of the filter drum, making removal difficult and affecting filtration efficiency. Therefore, a new rotary microfiltration machine is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a rotary microfilter that solves the problems of traditional rotary microfilters, which usually require an external power source such as a motor to drive the drum to rotate, resulting in additional energy consumption, and the filtered impurities easily adhering to the inside of the filter drum, making it inconvenient to remove the impurities and affecting the filtration efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rotary microfiltration machine includes a mounting box, a first support plate fixedly connected inside the mounting box, a filter roller movably sleeved inside the first support plate, a screw blade fixedly connected inside the filter roller, a first mounting bracket fixedly connected above the mounting box, an inlet pipe fixedly sleeved inside the first mounting bracket, and the lower end of the inlet pipe being disposed inside the filter roller.

[0006] Furthermore, a second support plate is fixedly connected inside the mounting box, one end of the filter roller is movably sleeved on the second support plate, and a baffle plate is fixedly connected to one side of the inside of the filter roller.

[0007] Furthermore, a first drain trough is fixedly connected inside the mounting box, a second support plate is fixedly connected to one side of the first drain trough, and a drain pipe is fixedly connected to the outside of the mounting box.

[0008] Furthermore, a cleaning water pump is fixedly connected to the top of the mounting box, a connecting pipe is fixedly connected to one side of the water outlet of the cleaning water pump, several nozzles are fixedly connected at equal intervals below the connecting pipe, and second mounting brackets are fixedly connected to both sides of the connecting pipe. A first support plate and a second support plate are fixedly connected to the bottom of the two second mounting brackets, respectively.

[0009] Furthermore, a second drain trough is fixedly connected inside the installation box, one end of the second drain trough is set inside the filter drum, and a connection port is opened at the bottom of the second drain trough.

[0010] Furthermore, a control panel is fixedly connected to one side of the mounting box, and the control panel is electrically connected to a cleaning water pump. A drain pipe is fixedly connected to the lower side of one side of the mounting box.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the design of the screw blades, enables the filter drum to rotate self-drivenly, reducing additional energy consumption and facilitating the discharge of impurities. The installation box is placed on a horizontal plane, and an external power supply is connected via the control panel. Wastewater is injected through the inlet pipe, entering the filter drum. The wastewater is filtered by the filter drum, leaving impurities inside. The filtered wastewater is discharged through the drain pipe. Simultaneously, the wastewater pushes the screw blades, which in turn drive the filter drum to rotate. During rotation, the filter drum discharges the filtered impurities into the first drainage trough. Furthermore, the rotating screw blades further enhance the movement of the impurities, causing them to fall into the first drainage trough and be discharged through the drain pipe. This design enables the filter drum to rotate self-drivenly, reducing additional energy consumption and facilitating the discharge of impurities.

[0012] 2. This utility model, through the provision of a second drain trough, can further clean the surface of the filter drum, thereby improving filtration efficiency. When cleaning the filter drum is required, a cleaning water pump is activated to draw cleaning water from the outside and inject it into the connecting pipe. The cleaning water in the connecting pipe is then sprayed onto the surface of the filter drum through a nozzle. As the filter drum rotates, the cleaning water can clean the surface of the filter drum 360 degrees. The cleaning water carries impurities into the second drain trough, and the impurities in the second drain trough are discharged into the first drain trough through the connecting port. Through this design, the surface can be further cleaned, thereby improving filtration efficiency.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-5 As shown, a rotary microfiltration machine includes a mounting box 1. A first support plate 5 is fixedly connected inside the mounting box 1. A filter roller 6 is movably sleeved inside the first support plate 5. A screw blade 9 is fixedly connected inside the filter roller 6. A first mounting bracket 3 is fixedly connected above the mounting box 1. A water inlet pipe 4 is fixedly sleeved inside the first mounting bracket 3. One lower end of the water inlet pipe 4 is set inside the filter roller 6. By adopting the above technical solution, the structure of the filter roller 6 is a cylindrical plastic frame. A filter screen is installed on the outer wall of the frame. Wastewater entering the filter roller 6 will be filtered through the filter screen. The screw blade 9 is fixedly connected to the cylindrical plastic frame. The angle of the sewage discharged into the filter drum 6 through the water inlet pipe 4 is designed so that the sewage can impact the screw blade 9, thereby driving the filter drum 6 to rotate through the screw blade 9, so that the filter drum 6 can achieve self-drive. A limiting baffle is installed on the outer side of the filter roller 6, and the inner side of the limiting baffle abuts against the first support plate 5, which can limit the filter roller 6. During use, the inlet end of the inlet pipe 4 is usually equipped with an inlet water pump to facilitate the extraction of sewage into the microfiltration machine for treatment, and the inlet water pump can ensure that the sewage has sufficient impact force.

[0022] The installation box 1 is fixedly connected to the second support plate 7. One end of the filter roller 6 is movably sleeved on the second support plate 7. A baffle plate 8 is fixedly connected to one side of the inside of the filter roller 6. By adopting the above technical solution, a limit baffle is installed on the outside of the filter roller 6, so that the filter roller 6 is limited to the first support plate 5 and the second support plate 7 and can only rotate without displacement. The baffle plate 8 is located on the side near the water inlet pipe 4 to prevent sewage from overflowing when sewage enters the filter drum 6.

[0023] The first sewage trough 10 is fixedly connected inside the mounting box 1. The second support plate 7 is fixedly connected to one side of the first sewage trough 10. The sewage pipe 13 is fixedly connected to the outside of the mounting box 1. By adopting the above technical solution, the first sewage trough 10 is inclined and is located on the lower side of the filter drum 6. Impurities in the sewage discharged from the filter drum 6 can be collected and fall into the first sewage trough 10. The first drain trough 10 is concave in the middle, which allows impurities to be better concentrated in the middle of the first drain trough 10 and slide down, and can be discharged through the drain pipe 13.

[0024] A cleaning water pump 14 is fixedly connected to the top of the mounting box 1. A connecting pipe 15 is fixedly connected to the water outlet end of one side of the cleaning water pump 14. Several nozzles 17 are fixedly connected at equal intervals below the connecting pipe 15. Second mounting brackets 16 are fixedly connected to both sides of the connecting pipe 15. A first support plate 5 and a second support plate 7 are fixedly connected to the bottom of the two second mounting brackets 16 respectively. By adopting the above technical solution, the cleaning water pump 14 can inject cleaning water into the connecting pipe 15. The connecting pipe 15 is located on one side above the filter roller 6, and several nozzles 17 are evenly arranged in a row. The cleaning water discharged from the nozzles 17 can be evenly sprayed onto the surface of the filter roller 6.

[0025] The installation box 1 is fixedly connected to the inside of the second sewage trough 11. One end of the second sewage trough 11 is set inside the filter roller 6. A connection port 12 is opened at the bottom of the second sewage trough 11. By adopting the above technical solution, the connection port 12 is set above the first sewage trough 10. After the cleaning water is sprayed onto the filter roller 6, the cleaning water can carry the impurities into the second drain tank 11. The second drain trough 11 is inclined so that cleaning water carrying impurities falls into the connection port 12; The position of the second drain trough 11 corresponds to the nozzle 17.

[0026] A control panel 2 is fixedly connected to one side of the mounting box 1. The control panel 2 is electrically connected to the cleaning water pump 14. A drain pipe 18 is fixedly connected to the lower side of one side of the mounting box 1. By adopting the above technical solution, the cleaning water pump 14 can be controlled through the control panel 2. The drain pipe 18 is positioned between the first support plate 5 and the second support plate 7.

[0027] It should be noted that in actual use, the installation box 1 is placed on a horizontal plane, and an external power supply is connected through the control panel 2. Wastewater is injected through the inlet pipe 4 and enters the filter drum 6. The wastewater is filtered by the filter drum 6, and the impurities in the wastewater remain in the filter drum 6. The wastewater is discharged from the drain pipe 18 after being filtered by the filter drum 6. At the same time, the wastewater pushes the screw blade 9, which in turn drives the filter drum 6 to rotate. During the rotation of the filter drum 6, the filtered impurities are discharged into the first sewage tank 10. Furthermore, the screw blade 9 can further strengthen the movement of the impurities during the rotation. The impurities that fall into the first sewage tank 10 are discharged from the sewage pipe 13.

[0028] When cleaning the filter roller 6, the cleaning water pump 14 is started to draw cleaning water from the outside and inject it into the connecting pipe 15. The cleaning water in the connecting pipe 15 is then sprayed onto the surface of the filter roller 6 through the nozzle 17. As the filter roller 6 rotates, the cleaning water can clean the surface of the filter roller 6 in 360 degrees. The cleaning water carries impurities into the second drain trough 11. The impurities in the second drain trough 11 are discharged into the first drain trough 10 through the connecting port 12.

[0029] This utility model provides a rotary microfilter that solves the problems of traditional rotary microfilters, which usually require an external power source such as a motor to drive the drum rotation, resulting in additional energy consumption, and the filtered impurities easily adhering to the inside of the filter drum 6, making it inconvenient to remove the impurities and affecting the filtration efficiency. It is more practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
