Abstract
Description
Technical Field
[0001] The utility model relates to the field of wastewater filtration equipment, in particular to a device for wastewater filtration. Background Art
[0002] In organic wastewater, in addition to organic substances, there are also insoluble solid impurities. Before the biochemical treatment of organic wastewater, it is necessary to use a filtration device for preliminary filtration to remove solid impurities.
[0003] The demand for the treatment of organic wastewater is large, while the capacity of the filtration device for solid impurities is limited. It is necessary to stop the machine for cleaning solid impurities or replacing the filter screen. Otherwise, the filter screen is easily blocked, resulting in the overflow of wastewater, and the continuous filtration treatment of wastewater cannot be carried out. Frequent manual maintenance is required, and the labor cost is high. Improvements are needed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a device for wastewater filtration, which automatically monitors the filtration effect and switches the filter screen to reduce the maintenance frequency.
[0005] To achieve this purpose, the utility model adopts the following technical solutions:
[0006] A device for wastewater filtration includes: a gantry, a turntable, a filter screen, a flow guide cylinder, a liquid level sensor, a controller, a wastewater tank and an adapter plate. The turntable is rotatably arranged below the gantry, the adapter plate is arranged below the turntable, an annular liquid receiving groove is concavely arranged at the top of the adapter plate, a drain valve communicated with the annular liquid receiving groove is arranged at the bottom of the adapter plate, stepped holes located above the annular liquid receiving groove are annularly and spacedly arranged at the top of the turntable, the flow guide cylinder is arranged in the stepped holes and extends upward, the filter screen is arranged in the flow guide cylinder, the wastewater tank is arranged on the gantry, an electromagnetic valve pointing downward to one of the flow guide cylinders is arranged at the bottom of the wastewater tank, the liquid level sensor is arranged on the gantry and on one side of the electromagnetic valve, the liquid level sensor is connected to the controller for detecting the liquid level in the flow guide cylinder, and the controller is connected to the electromagnetic valve to close the electromagnetic valve when the liquid level in the flow guide cylinder exceeds the standard.
[0007] Wherein, a cam divider for driving its rotation is arranged below the turntable, the cam divider is driven by a motor, and the controller is connected to the motor for rotation control.
[0008] Wherein, the adapter plate is arranged on the housing of the cam divider.
[0009] Wherein, a drain pipe is arranged at the bottom of the drain valve.
[0010] Wherein, a limiting ring is integrally arranged at the bottom of the flow guide cylinder.
[0011] One side of the wastewater tank is provided with a wastewater inlet pipe.
[0012] Advantages of the present utility model: A device for wastewater filtration. After the solenoid valve is opened, the wastewater in the wastewater tank flows downward through the solenoid valve into the guide cylinder, is filtered by the filter screen in the guide cylinder, then flows into the lower annular liquid receiving tank, and finally is discharged through the liquid discharge pipe for subsequent further treatment. As the filtration progresses, more and more solid impurities remain in the guide cylinder, and the filter screen is partially blocked, resulting in a decline in the filtration effect. At this time, the liquid level in the guide cylinder gradually rises. When the liquid level exceeds the standard, the solenoid valve is closed, the adjacent guide cylinder and filter screen are switched by the rotation of the turntable, and the solenoid valve is opened to continue filtration, improving the filtration efficiency and reducing the frequency and cost of manual maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The following combines Figure 1 and further illustrates the technical solution of the present utility model through specific embodiments.
[0015] Such as Figure 1 the device for wastewater filtration shown, including: gantry 1, turntable 2, filter screen 7, guide cylinder 6, liquid level sensor 5, controller 9, wastewater tank 3 and adapter plate 11. The wastewater tank 3 is arranged on the gantry. One side of the wastewater tank 3 is provided with a wastewater inlet pipe 4 to introduce the wastewater to be filtered into the wastewater tank 3.
[0016] The turntable 2 is rotatably arranged below the gantry 1. In this embodiment, a cam divider 12 for driving its rotation is arranged below the turntable 2. The cam divider 12 is driven by a motor, and the controller 9 is connected to the motor for rotation control. The automation degree is high.
[0017] The adapter plate 11 is arranged below the turntable 2. In this embodiment, the adapter plate 11 is arranged on the housing of the cam divider 12 and fixed by screws. The structure is stable and does not rotate with the turntable 2.
[0018] Such as Figure 1 shown, the top of the adapter plate 11 is concavely provided with an annular liquid receiving tank 8, and the bottom of the adapter plate 11 is provided with a drain valve 15 communicating with the annular liquid receiving tank 8. In this embodiment, a drain pipe 16 is arranged at the bottom of the drain valve 15, and the filtered wastewater is discharged through the drain pipe 16 for subsequent further biochemical treatment.
[0019] On the top of the turntable 2, stepped holes 14 are annularly and spacedly arranged above the annular liquid receiving tank 8. The guide cylinder 6 is arranged in the stepped hole 14 and extends upward. The filter screen 7 is arranged in the guide cylinder 6. A limiting ring 13 is integrally arranged at the bottom of the guide cylinder 6 to limit the filter screen 7, so that the filter screen 7 can be taken out together with the guide cylinder 6, which is convenient for maintenance.
[0020] The waste water flowing into the guide cylinder 6 can be filtered by the filter screen 7 and then flow into the lower annular liquid receiving tank 8 through the stepped hole 14. The annular structure of the annular liquid receiving tank 8 enables the waste water in the stepped hole 14 to still flow downward into the annular liquid receiving tank 8 when the turntable 2 rotates, avoiding the leakage problem.
[0021] An electromagnetic valve 10 pointing downward to one of the guide cylinders 6 is arranged at the bottom of the waste water tank 3. After the electromagnetic valve 10 is opened, the waste water in the waste water tank 3 flows downward through the electromagnetic valve 10 into the guide cylinder 6, is filtered by the filter screen 7 in the guide cylinder 6 and then flows into the lower annular liquid receiving tank 8, and finally is discharged through the drain pipe 16 for subsequent further treatment.
[0022] The liquid level sensor 5 is arranged on the gantry 1 and on one side of the electromagnetic valve 10. The liquid level sensor 5 is connected to the controller 9 to detect the liquid level in the guide cylinder 6. The controller 9 is connected to the electromagnetic valve 10. When the liquid level in the guide cylinder 6 exceeds the standard, the electromagnetic valve 10 is closed. By rotating the turntable 2 to switch to an adjacent guide cylinder and filter screen and opening the electromagnetic valve 10 to continue filtering, the closing time of the electromagnetic valve 10 is shortened and the filtering efficiency is improved. The number of guide cylinders 6 is 2 to 6. Using multiple guide cylinders 6 can extend the maintenance interval and reduce the frequency and cost of manual maintenance.
[0023] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
