Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and in particular to a sewage treatment device. Background Technology

[0002] Wastewater treatment equipment is mainly used to treat and filter wastewater to ensure that the discharged wastewater meets the required standards. The core component of wastewater treatment equipment is the filter module, which has filter plates for filtering wastewater. Through the filtering action of the filter plates, solid impurities in the wastewater are removed.

[0003] In existing wastewater treatment equipment, the filter modules need to be replaced after a period of use for maintenance. However, replacing filter modules in existing wastewater treatment equipment is inconvenient, resulting in a lengthy replacement process and impacting wastewater treatment efficiency. Utility Model Content

[0006] The wastewater treatment equipment of this utility model includes a housing and a filter module;

[0007] The filter module has hanging plates on both sides, and a support assembly is provided in the housing. The support assembly has slots for accommodating and supporting the hanging plates so that the filter module is suspended in the housing.

[0008] Furthermore, the support assembly includes a first support frame and a second support frame arranged in parallel at intervals, and both the first support frame and the second support frame are provided with the slot.

[0009] Furthermore, both the first support frame and the second support frame are provided with U-shaped grooves, which constitute the slots. The two slots are arranged facing each other. Both the first support frame and the second support frame are provided with clearance notches to avoid the hanging plate, so that the hanging plate can enter the slot.

[0010] Furthermore, it also includes a limiting member used to restrict the displacement of the filter module.

[0011] Furthermore, the support component is provided with a first through hole, the hanging plate is provided with a second through hole, and the limiting member is a pin that passes through the first through hole and the second through hole.

[0012] Furthermore, the filter module also includes a cover plate with a handle.

[0013] Furthermore, the filtration module includes a liquid extraction component, a plate frame, and multiple filter plates located in the plate frame. The plate frame and the multiple filter plates form a filtration cavity. The filtration cavity has an upper opening, and a cavity cover is provided at the upper opening. The cavity cover has a liquid outlet. The liquid extraction component is used to extract the purified water in the filtration cavity from the liquid outlet.

[0014] The plate frame has a central symmetry plane extending in the vertical direction, and two filter plates are symmetrically arranged on both sides of the central symmetry plane. The two filter plates have a set inclination angle with the central symmetry plane so that impurity particles are detached from the filter plates due to their own weight.

[0015] Furthermore, the support components are provided in two sets and are arranged at intervals along the depth direction of the housing. The filter module has an upright position and an inverted position. The upper support component is used to suspend the filter module in the upright position, and the lower support component is used to suspend the filter module in the inverted position.

[0016] Furthermore, the housing is provided with a liquid inlet, the axis of which is parallel to the plane on which the filter plate is located, so that the sewage disturbs the impurity particles on the surface of the filter plate.

[0017] Furthermore, the housing has a main outlet pipe, and multiple filter modules are arranged in parallel inside the housing. Each of the multiple filter modules has a control valve at the end of its pumping assembly and is connected to the main outlet pipe through the control valve. The control valve has an open state and a closed state. When it is in the open state, the filter module filters the wastewater. When it is in the closed state, the filter module is in a self-cleaning state.

[0040] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0041] The following is in conjunction with the instruction manual appendix. Figure 1 To be continued Figure 6 This paper introduces the wastewater treatment equipment of this utility model.

[0042] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the wastewater treatment equipment includes a housing 100 and a filter module 200.

[0043] The filter module 200 has hanging plates 210 on both sides, and a support assembly is provided in the housing 100. The support assembly has slots 121 for accommodating and supporting the hanging plates 210 so that the filter module 200 is suspended in the housing 100.

[0044] The wastewater treatment equipment of this application achieves rapid replacement through a suspended connection structure between the housing 100 and the filter module 200. The housing 100 serves as the basic structure of the equipment, providing installation space. The filter module 200 is connected to the slots 121 of the support components via side mounting plates 210. When replacement is needed, simply lift the filter module 200 upwards to disengage the mounting plates 210 from the slots 121 for disassembly; installation is completed by reversing the operation. This shortens the replacement time for a single filter module 200 and improves wastewater treatment efficiency.

[0045] In some embodiments, the support assembly includes a first support frame 110 and a second support frame 120 arranged in parallel at intervals, and both the first support frame 110 and the second support frame 120 are provided with the slot 121.

[0046] Specifically, the first support frame 110 and the second support frame 120 can be formed by welding metal profiles or by injection molding engineering plastics. The inner wall of the slot 121 can be provided with anti-slip textures or a rubber pad to enhance friction. The spacing between the support frames can be adjusted according to the weight of the filter module 200.

[0047] By using a parallel, spaced-apart double-support frame structure, the filter module 200 mounting plate 210 can be fixed simultaneously at two support points. This dual-point support design effectively distributes the suspension load, avoiding stress concentration issues that are common with single-point support. The parallel-arranged support frames provide lateral restraint, preventing the filter module 200 from shaking or shifting during operation and reducing the risk of detachment due to vibration. The slot 121 structure ensures accurate positioning of the mounting plate 210 while facilitating installation and disassembly, simplifying maintenance procedures.

[0048] Furthermore, in some of these embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, both the first support frame 110 and the second support frame 120 are provided with U-shaped grooves, which form the slots 121. The two slots 121 are arranged facing each other. Both the first support frame 110 and the second support frame 120 are provided with clearance notches 122 for avoiding the hanging plate 210, so that the hanging plate 210 can enter the slots 121.

[0049] Specifically, the cross-sectional shape of the U-shaped groove can be a standard U-shape or a variable cross-section U-shape. The avoidance notch 122 can be implemented in ways including but not limited to: making a rectangular notch, an arc notch, or a stepped notch on the side wall of the support frame, and the depth of the notch must be greater than the thickness of the hanging plate 210.

[0050] This embodiment provides stable lateral constraints through a U-shaped groove structure, while the opposing slots 121 form bidirectional limiting, and the clearance notch 122 solves the spatial interference problem of the installation path. Specifically, after the mounting plate 210 enters the installation position through the clearance notch 122, it can complete the positioning by sliding along the axial direction of the U-shaped groove. The entire process does not require additional lateral force, thus avoiding repeated adjustments during installation, resulting in high positioning accuracy and short installation time.

[0051] In some embodiments, in order to prevent the filter module 200 from shifting within the housing 100, the wastewater treatment equipment further includes a limiting member 123, which is used to restrict the displacement of the filter module 200.

[0052] Specifically, the support assembly is provided with a first through hole 125, the hanging plate 210 is provided with a second through hole 211, and the limiting member 123 is a pin that passes through the first through hole 125 and the second through hole 211.

[0053] The first through hole 125 and the second through hole 211 form a coaxial channel after the filter module 200 is suspended in place. The pin can be made of a cylindrical metal rod or engineering plastic material, with a diameter slightly smaller than the inner diameter of the through hole to achieve a tight fit. As a preferred embodiment, the end of the pin can be equipped with an anti-dislodgement buckle or a threaded fastening structure to prevent the pin from accidentally falling off under vibration. In addition, the edge of the through hole can be chamfered to reduce the frictional resistance when the pin is inserted.

[0054] This embodiment achieves dual positioning functionality through the mechanical engagement of the pin and the through hole: lateral positioning is accomplished by the slot 121 of the support component, while longitudinal positioning is achieved by the through-hole pin structure. Therefore, when the filter module 200 is subjected to water flow impact or equipment vibration, the contact surface between the pin and the through hole wall generates a counterforce, thereby counteracting the displacement tendency, improving positioning reliability, and eliminating the need for complex drive mechanisms or sensors.

[0055] In some embodiments, the filtration module 200 includes a liquid extraction assembly 220, a plate frame 230, and a plurality of filter plates 240 located within the plate frame 230. The plate frame 230 and the plurality of filter plates 240 form a filtration chamber. The filtration chamber has an upper opening, and a chamber cover 250 is provided at the upper opening. The chamber cover 250 has a liquid outlet 251, and the liquid extraction assembly 220 is used to extract purified water from the filtration chamber through the liquid outlet 251. The chamber cover 250 also has a vent 252 to balance air pressure. For easier movement of the filtration module 200, a handle 253 is also provided on the chamber cover 250.

[0056] The plate frame 230 has a central symmetry plane extending in the vertical direction. Two filter plates 240 are symmetrically arranged on both sides of the central symmetry plane. The two filter plates 240 have a set inclination angle with the central symmetry plane so that impurity particles are removed from the filter plates 240 due to their own weight.

[0057] Specifically, the liquid extraction assembly 220 includes an outlet pipe 221 and a liquid extraction branch pipe 222, which is located in the filtration chamber and has a water passage. The outlet pipe 221 is connected to the liquid extraction branch pipe 222 and extends from the outlet port 251. The plate frame 230 is preferably made of stainless steel to enhance structural strength. The filter plate 240 has a microporous structure with filtration function, such as a microporous foam ceramic filter plate. The tilt angle is specifically achieved by pre-setting a fixed-angle mounting slot on the plate frame 230.

[0058] The inclined filter plate 240 structure utilizes gravity to automatically detach impurity particles from its surface. The modular filter chamber design forms a complete filtration-liquid extraction channel. The integration of the housing 100 and the filter module 200 provides structural support and a liquid inlet channel. The physical tilt design enables automatic impurity removal, allowing maintenance of the filter module 200 without shutdown and backwashing. This avoids damage to the filter module 200 caused by traditional backwashing methods, thereby improving filtration efficiency, reducing maintenance frequency, and extending the service life of the filter module 200.

[0059] Preferably, the set tilt angle is greater than or equal to 5° and less than or equal to 45°. This tilt angle range ensures that impurities are removed in time while avoiding structural instability caused by excessive angle.

[0060] Specifically, the plate frame 230 has multiple mounting positions that are adapted to and correspond one-to-one with the filter plate 240. The filter plate 240 is fixed in the mounting positions. By setting a set tilt angle for the mounting positions, the tilt angle of the filter plate 240 can be set. The set tilt angle is further preferably 10°-30°. This range ensures the effect of impurity sliding off while facilitating the compact arrangement of the filter modules 200200. For example, it can be 10°, 20°, or 30°. In other embodiments, it can also be 5°, 40°, or 45°.

[0061] In some embodiments, two sets of support components are provided and are spaced apart along the depth direction of the housing 100. The filter module 200 has an upright position and an inverted position. The upper support component is used to suspend the filter module 200 in the upright position, and the lower support component is used to suspend the filter module 200 in the inverted position.

[0062] Specifically, the support components can be made of metal brackets or engineering plastics, and the distance between the two sets of support components can be adjusted according to the size of the filter module 200. The depth and width of the slot 121 must match the hanging plate 210 to ensure suspension stability. As a preferred embodiment, the support components can be equipped with a height adjustment mechanism to accommodate filter modules 200 of different sizes. The size of the clearance notch 122 must be greater than the thickness of the hanging plate 210 to ensure that the hanging plate 210 can smoothly enter the slot 121.

[0063] By setting two sets of support components corresponding to different suspension positions, the upright or inverted suspension method can be selected according to the density difference of impurity particles. When the filter module 200 is in the upright position, impurity particles with a density greater than water slide down the inclined filter plate 240 under the action of gravity; when it is in the inverted position, impurity particles with a density less than water can float up and detach from the filter plate 240. This realizes the self-cleaning function of the filter module 200, significantly reducing the frequency of manual maintenance and improving the operating efficiency of the equipment.

[0064] In some embodiments, the housing 100 is provided with a liquid inlet 130, the axis of which is parallel to the plane on which the filter plate 240 is located, so that the sewage disturbs the impurity particles on the surface of the filter plate 240.

[0065] Specifically, the design of the inlet 130's axis being parallel to the plane of the filter plate 240 can be achieved in the following ways: the inlet 130 adopts a horizontal straight pipe structure, with its central axis parallel to the extended plane of the filter plate 240; or it adopts an inclined pipe structure, with the outlet direction parallel to the plane of the filter plate 240 by adjusting the angle. As a preferred embodiment, the inlet 130 can be equipped with a guide plate for precise control of the water flow direction. In addition, the inlet 130 can be designed as a rotatable structure to facilitate adjustment of the inlet angle according to actual needs.

[0066] The directional water inlet design allows the wastewater flow to directly impact the surface of the filter plate 240, using hydrodynamic disturbance to dislodge attached impurities. Specifically, firstly, continuous water flow prevents impurity accumulation and reduces the frequency of downtime for cleaning; secondly, the parallel water inlet method enhances the shearing effect of the fluid on the surface of the filter plate 240, improving impurity removal efficiency; and finally, the structure is simple and reliable, achieving self-cleaning without the need for an additional power unit.

[0067] In some embodiments, the housing 100 has a main outlet pipe 140, and multiple filter modules 200 are arranged in parallel inside the housing 100. The end of the liquid extraction component 220 of each filter module 200 is provided with a control valve 150 and connected to the main outlet pipe 140 through the control valve 150. The control valve 150 has an open state and a closed state. When it is in the open state, the filter module 200 filters the sewage. When it is in the closed state, the filter module 200 is in a self-cleaning state.

[0068] Specifically, the control valve 150 can be controlled by an electric ball valve, butterfly valve, or solenoid valve, wherein the electric actuator can receive PLC signals to achieve automatic switching. The diameter design of the main outlet pipe 140 needs to meet the flow requirements when multiple filter modules 200 drain simultaneously. The parallel arrangement of the filter modules 200 includes, but is not limited to: horizontal side-by-side arrangement, ring array arrangement, or layered three-dimensional arrangement. The self-cleaning state can be achieved by combining the principle of gravity sedimentation. When the valve is closed, the liquid in the filter chamber stops flowing, and the impurities attached to the surface of the filter plate 240 naturally fall off under the action of gravity.

[0069] This embodiment achieves parallel operation of filtration and cleaning through modular parallel design and independent valve control. Specifically, when some filter modules 200 require cleaning due to impurity accumulation, only the corresponding valve needs to be closed to put them into self-cleaning mode, while the remaining modules can continue filtration, thus avoiding the drawback of traditional equipment requiring complete shutdown for cleaning. The switching of the working state of the filter modules 200 only requires valve control, without disassembly or manual intervention, significantly improving the continuity of equipment operation. Furthermore, the centralized drainage design of the main outlet pipe 140 simplifies the pipeline layout and facilitates maintenance and management. This embodiment minimizes the impact of cleaning operations on production efficiency while ensuring filtration effectiveness, and eliminates the need for cleaning methods such as backflushing that may damage the filter media.

[0070] In some embodiments, the lower part of the housing 100 has a conical section, and a drain port 160 is provided at the bottom of the conical section. During equipment operation, the conical structure enables deposited impurity particles to automatically collect along the inclined surface under the action of gravity and be discharged from the drain port 160.

[0071] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
