Description

Non-stop wastewater combination filter Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a non-stop combined sewage filter. Background Technology

[0002] In the field of wastewater treatment, traditional wastewater filtration equipment uses filter cartridges to trap suspended solids, colloids and other impurities in wastewater, thereby achieving solid-liquid separation to purify water quality. Its core function is to improve the reusability of wastewater or its ability to meet discharge standards.

[0003] However, existing traditional wastewater filters generally adopt a single-cartridge filtration structure, which has significant drawbacks: when the filter cartridge reaches saturation due to impurities, the system must be shut down for cleaning or replacement. This process forces an interruption of the wastewater treatment process, affecting production continuity and potentially leading to water quality deterioration due to temporary wastewater storage during shutdown. The intermittent operation of traditional single-cartridge filtration equipment has become a technical bottleneck restricting the improvement of treatment efficiency. Therefore, a non-stop combined wastewater filter was designed. Summary of the Invention

[0004] In order to overcome the shortcomings of traditional single-cartridge filter equipment that requires shutdown for cleaning, the technical problem to be solved by this utility model is to provide a combined sewage filter that can be used without shutting down the machine.

[0005] The technical implementation scheme of this utility model is as follows: a non-stop combined sewage filter, including a shell, a fixed plate, a motor, a water storage tank, an outlet valve, a first connecting plate, filter elements, a connecting pipe, and a switching mechanism. A fixed plate is fixedly connected to one side of the shell, and a motor is installed at the other end of the fixed plate. A water storage tank is provided at the bottom of the shell, and the shell and the water storage tank are connected by a pipe. An outlet valve is installed on the water storage tank. A first connecting plate is installed on the output shaft of the motor, and three filter elements are installed on the first connecting plate. The other end of the filter elements is connected to a connecting pipe, and a switching mechanism is installed on the shell near the connecting pipe.

[0006] Furthermore, the switching mechanism includes a sealing block, a fixing rod, a water inlet pipe, and a connecting bucket. The fixing rod is installed near the connecting pipe on the outer shell, and the other end of the fixing rod is fixedly connected to the water inlet pipe. The bottom end of the water inlet pipe is installed with a connecting bucket. The three connecting pipes are fixedly connected to a sealing block, and the sealing block has water inlets leading to the three connecting pipes respectively.

[0007] Furthermore, the water inlet at the bottom of the sealing block forms a dynamic seal with the conical sealing surface of the connecting bucket.

[0008] Furthermore, it also includes a flow rate sensor, which is installed on the pipe between the outer casing and the water tank.

[0009] Furthermore, it also includes a limiting ring and a second connecting plate. The three filter elements are fixedly connected to the second connecting plate near the connecting pipe. The housing is installed with a limiting ring near the second connecting plate. The second connecting plate is slidably connected to the limiting ring.

[0010] Furthermore, it also includes a three-jaw ratchet and a spring-loaded block. The three-jaw ratchet is mounted on the output shaft of the motor, and a spring-loaded block is mounted on the end of the fixed plate near the three-jaw ratchet. The spring-loaded block meshes with the three-jaw ratchet.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a three-filter cartridge rotation mechanism, which enables the device to trigger an automatic switching program after the filter cartridges become clogged, achieving uninterrupted filtration. This improves efficiency compared to traditional single-filter cartridge equipment and avoids interruptions in wastewater treatment due to downtime maintenance.

[0013] 2. This utility model uses a flow rate sensor to achieve real-time monitoring and automatic switching of filter element blockage status, reducing the frequency of manual intervention, reducing operational errors, and improving system operational stability. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example: A non-stop combined sewage filter, as shown in Figures 1-5, includes a housing 1, a fixed plate 101, a motor 2, a water storage tank 4, an outlet valve 5, a first connecting plate 6, filter elements 7, a connecting pipe 10, and a switching mechanism. The fixed plate 101 is fixedly connected to one side of the housing 1, and the motor 2 is installed at the other end of the fixed plate 101. The water storage tank 4 is located at the bottom of the housing 1, and the housing 1 and the water storage tank 4 are connected by a pipe. The outlet valve 5 is installed on the water storage tank 4. The first connecting plate 6 is installed on the output shaft of the motor 2. Three filter elements 7 are installed on the first connecting plate 6, and the other end of the filter elements 7 is connected to the connecting pipe 10. The switching mechanism is installed on the housing 1 near the connecting pipe 10.

[0022] As shown in Figures 2-4, a fixing rod 12 is installed near the connecting pipe 10 on the outer shell 1. The other end of the fixing rod 12 is fixedly connected to the water inlet pipe 13. A connecting bucket 14 is installed at the bottom of the water inlet pipe 13. A sealing block 11 is fixedly connected to the three connecting pipes 10. The sealing block 11 has water inlets leading to the three connecting pipes 10 respectively. The design of the switching mechanism allows sewage to enter different filter elements 7 in an orderly manner through the water inlet of the water inlet pipe 13, the connecting bucket 14 and the water inlet of the sealing block 11.

[0023] As shown in Figures 3 and 4, the bottom water inlet of the sealing block 11 forms a dynamic seal with the conical sealing surface of the connecting bucket 14. The sealing material is polytetrafluoroethylene, which effectively prevents sewage leakage during the switching process and ensures the stability and efficiency of the filtration process.

[0024] As shown in Figures 1 and 2, a flow rate sensor 3 is installed on the pipe between the outer shell 1 and the water storage tank 4. It can monitor the flow rate of the filtered water in real time. Once the flow rate is detected to be lower than the set threshold, it can be determined that the filter element 7 is blocked, thereby triggering the automatic switching program. It does not require frequent manual intervention and realizes intelligent operation.

[0025] As shown in Figures 2 and 3, three filter elements 7 are fixedly connected to a second connecting plate 9 near the connecting pipe 10. A limiting ring 8 is installed on the outer shell 1 near the second connecting plate 9. The second connecting plate 9 is slidably connected to the limiting ring 8. This design enables the three filter elements 7 to remain stable when rotating, providing radial positioning and axial sliding guidance for the filter elements 7, preventing the filter elements 7 from shifting or shaking during rotation, and ensuring the accuracy of filter element 7 switching.

[0026] As shown in Figure 5, a three-jaw ratchet 15 is installed on the output shaft of the motor 2. A spring-loaded lever 16 is installed on one end of the fixed disk 101 near the three-jaw ratchet 15. The spring-loaded lever 16 meshes with the three-jaw ratchet 15. This design realizes unidirectional intermittent transmission. After the motor 2 drives the filter element 7 to rotate and switch positions, the three-jaw ratchet 15 can be locked by the spring-loaded lever 16 to prevent the transmission system from undergoing slight reversal due to factors such as water pressure fluctuations, thus ensuring the accuracy of the filter element 7 switching position.

[0027] Wastewater flows into the connecting hopper 14 through the inlet pipe 13, and enters the current bottom filter element 7 through the bottom inlet of the sealing block 11. Under the action of pressure difference, solid-liquid separation is completed: suspended solids, colloids and other impurities in the wastewater are intercepted by the filter element 7, and the filtered liquid flows into the bottom of the outer shell 1 through the outlet of the filter element 7, and enters the water storage tank 4 through the pipe to settle. At this time, the flow rate sensor 3 monitors the flow rate in the pipe in real time. When the flow rate is lower than the set threshold, it is determined that the filter element 7 is blocked, and the automatic switching program is triggered. The device drive motor 2 rotates 120° clockwise, driving the first connecting plate 6, the three filter elements 7 and the sealing block 11 to rotate synchronously. During the rotation, wastewater accumulates in the connecting hopper 14, so that the device can continuously supply water without stopping the machine. The connecting hopper 14 and the sealing block 11 maintain a conical surface seal to prevent wastewater leakage. When another filter element 7 rotates to the bottom position, the corresponding inlet of the sealing block 11 and the connecting hopper 14 are realigned, and the wastewater is switched to the other filter element 7 for filtration. After the motor 2 stops rotating, the three-jaw ratchet 15 engages and locks with the spring-loaded lever 16 to prevent the transmission system from undergoing slight reverse rotation due to water pressure fluctuations, thus ensuring the positioning accuracy of the filter element 7.
