Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an integrated wastewater treatment device with a protective structure. Background Technology

[0002] Integrated wastewater treatment equipment is a complete set of equipment that integrates multiple units of a wastewater treatment process into one or more compact boxes or tanks. It is mainly used to treat small- to medium-scale domestic sewage and some organic industrial wastewater, and is particularly suitable for decentralized wastewater treatment scenarios, serving as a powerful supplement to traditional large-scale wastewater treatment plants.

[0003] Installing a filter screen at the inlet of an integrated wastewater treatment system is a very important and proactive protective measure. It can actively intercept and screen out large solid impurities carried in the wastewater to prevent clogging of the treatment units inside the integrated wastewater treatment system.

[0004] Traditional filter screens are often fixed to the water inlet using flanges. This requires unscrewing numerous bolts during disassembly, making it inconvenient for users to remove and clean the filter screen, and increasing the complexity of filter maintenance. Therefore, there is an urgent need for an integrated wastewater treatment device that allows for easy disassembly and cleaning of the filter screen's protective structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated wastewater treatment device with a protective structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated sewage treatment device with a protective structure includes a sewage treatment device body. An inlet is fixedly installed on the sewage treatment device body. A detachable filter assembly is installed in the middle of the inlet, and a filter screen is installed inside the filter assembly. A top member is fixedly installed on the top of the filter assembly. Locking members are movably installed on both sides of the top member. A pressure plate for pushing the locking members is vertically movably installed inside the top member through a screw. A locking cavity is adapted to each locking member on the inlet.

[0008] In addition, a preferred structure is that the middle of the water inlet has a cavity adapted to the filter assembly, multiple support rods are fixedly installed on the outer side of the cavity, and locking cavities are respectively opened on both sides of the cavity.

[0009] Furthermore, in a preferred configuration, both sides of the top member have inwardly opening movable cavities, and the pressure plate and locking member are adapted to move within the movable cavities.

[0010] Furthermore, in a preferred configuration, both sides of the bottom of the top member are provided with inclined surfaces, and both locking members on both sides are provided with matching inclined surfaces.

[0011] In addition, a preferred structure is that side plates are fixedly provided on both sides of the locking member, and side cavities are adapted to be opened on the inner wall of the movable cavity corresponding to the side plates. Multiple guide posts for guiding the side plates are fixedly provided in the side cavities, and springs connected to the side plates are installed in the side cavities.

[0012] In addition, in a preferred structure, a screw is provided at the top of the top member that rotates downwards, the screw extends into the movable cavity and is rotatably connected to the pressure plate, an anti-dropping component is fixedly provided at the bottom of the screw, and an anti-dropping cavity is provided on the pressure plate corresponding to the anti-dropping component.

[0013] The beneficial effects of this utility model are as follows: by installing a filter assembly at the water inlet, large solid impurities in the sewage can be intercepted to prevent them from clogging the sewage treatment equipment. By rotating the screw, the locking part can be adjusted, and the filter assembly can be fixedly installed by the matching and locking between the locking part and the locking cavity.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-9 An integrated wastewater treatment device with a protective structure includes a wastewater treatment device body 1. An inlet 2 is fixedly installed on the wastewater treatment device body 1. A detachable filter assembly 3 is installed in the middle of the inlet 2, and a filter screen 30 is installed inside the filter assembly 3. A top member 31 is fixedly installed on the top of the filter assembly 3. Locking members 6 are movably installed on both sides of the top member 31. A pressure plate 5 for pushing the locking members 6 is vertically movably installed inside the top member 31 via a screw 4. A locking cavity 22 is adapted to fit the locking member 6 on the inlet 2.

[0026] The inlet 2 has a cavity in the middle that is compatible with the filter assembly 3. Multiple support rods 21 are fixedly installed on the outer side of the cavity, and locking cavities 22 are respectively opened on both sides of the cavity. The support rods 21 can support the filter assembly 3 to ensure the installation stability of the filter assembly 3.

[0027] The top member 31 has inwardly opening movable cavities 32 on both sides, and the pressure plate 5 and the locking member 6 are adapted to move within the movable cavities 32. The bottom of the top member 31 has inclined surfaces on both sides, and the locking members 6 on both sides also have matching inclined surfaces. Through the matching inclined surfaces between the pressure plate 5 and the locking members 6, the pressure plate 5 can push the locking members 6 outwards via the inclined surfaces when moving downwards.

[0028] The locking member 6 has side plates 61 fixedly installed on both sides. The inner wall of the movable cavity 32 has corresponding side cavities 321 adapted to each side plate 61. Multiple guide posts 322 for guiding the side plates 61 are fixedly installed in each side cavity 321, and springs 323 connected to the side plates 61 are installed in each side cavity 321. The springs 323 allow the locking member 6 to automatically return to its original position within the movable cavity 32 when the pressure plate 5 is moved upwards.

[0029] The top of the top piece 31 is rotatably fitted with a screw 4, which extends into the movable cavity 32 and is rotatably connected to the pressure plate 5. An anti-detachment component 41 is fixedly installed at the bottom of the screw 4, and anti-detachment cavities 51 are correspondingly provided on the pressure plate 5 for each anti-detachment component 41. A knob is provided at the top of the screw 4, and a screw hole is provided on the top piece 31 corresponding to the screw 4, allowing the user to rotate the screw 4 vertically using the knob.

[0030] During the rotation of the screw 4, the anti-detachment component 41 rotates within the anti-detachment cavity 51, allowing the screw 4 to move synchronously with the top plate 5 when moving vertically. However, the screw 4 does not rotate when rotating, preventing the top plate 5 from rotating. It is worth noting that a pre-existing threaded self-locking mechanism is provided between the screw 4 and the screw hole to prevent the screw 4 from rotating on its own.

[0031] In this invention, the wastewater treatment equipment body 1 is equipped with a pretreatment unit, a biological treatment unit, a sedimentation unit, a disinfection module, and a sludge treatment system. Each unit is integrated into a corrosion-resistant housing, and is supplemented by power equipment such as water pumps and blowers to achieve efficient purification throughout the entire process. The specific wastewater treatment structures within the wastewater treatment equipment body 1 are all existing technologies and are not part of the main technical problems to be solved in this technical solution; therefore, they will not be described in detail.

[0032] Furthermore, when the user needs to install the filter assembly 3 on the water inlet 2, simply insert the filter assembly 3 into the water inlet 2. At this time, the filter screen 30 inside the filter assembly 3 is adapted and connected to the water inlet cavity inside the water inlet 2, and the locking parts 6 are all aligned with the locking cavity 22. It is worth noting that sealing elements are provided on the contact surfaces between the filter assembly 3 and the water inlet 2 to ensure the airtightness of the water inlet 2.

[0033] The user then simply rotates screw 4 downwards to move pressure plate 5 downwards simultaneously. This pushes the locking elements 6 on both sides outwards through the inclined surface between pressure plate 5 and locking elements 6, thus pushing the locking elements 6 into the locking cavity 22. At this time, springs 323 are stretched. This completes the fixed installation of filter assembly 3 and filter screen 30.

[0034] Furthermore, when the user needs to disassemble and clean the filter screen 30, simply rotate the screw 4 upwards to move the top plate 5 upwards simultaneously. At this time, the top plate 5 no longer pushes the locking member 6 outwards, and the locking member 6 can automatically return to the movable cavity 32 by the elastic force of the spring 323, thereby releasing the adapter jamming between the locking member 6 and the locking cavity 22. At this time, the user can directly pull the filter assembly 3 upwards to achieve disassembly.

[0035] Furthermore, the filter screen 30 is existing technology, so it will not be described in detail. Guide members are provided on both sides of the pressure plate 5 to ensure its stability during movement. Guide members are also provided on both sides of the filter assembly 3 to ensure that the filter assembly 3 can be stably installed in the cavity in the middle of the inlet 2.

[0036] In this utility model, by installing a filter assembly 3 at the inlet 2, large solid impurities in the sewage can be intercepted to prevent them from clogging the sewage treatment equipment body 1. By rotating the screw 4, the locking part 6 can be adjusted, thereby achieving the fixed installation of the filter assembly 3 through the matching and locking between the locking part 6 and the locking cavity 22. This method of assembling the filter assembly 3 is simple and convenient, and it is easy for users to disassemble and clean the filter assembly 3 in the later stage.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
