Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a non-powered drum waste residue filter device. Background Technology

[0002] Wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus fully utilizing water resources. Industrial production generates many types of pollutants, with significant differences in the types and concentrations of pollutants produced by different industries. In the treatment of wastewater containing dye residue, the primary method is filtration to remove the residue. This filtration method includes two treatment units: screen filtration and general filtration. The former uses equipment such as bar screens and sieves, while the latter uses sand filters and microfiltration machines.

[0003] Existing wastewater filtration devices use an external motor to drive a filter with a filter screen, causing wastewater to flow back and forth and thus filtering the waste. This structure requires an additional drive mechanism, making it not only complex but also costly. Furthermore, existing devices use horizontally mounted support rods to support the filter screen. This structure is prone to waste accumulation near the support rods during filtration, making it difficult to remove and clogging the filter screen over time, thus affecting filtration efficiency. Therefore, it is necessary to further improve existing filtration devices. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a non-powered drum waste sludge filtration device that can effectively solve the problems of complex structure, high operating cost, and poor filtration effect of existing waste sludge filtration devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-powered drum waste sludge filtration device includes a mounting frame and a filter assembly. The mounting frame has a mounting cavity, and an inlet and an outlet respectively connected to the mounting cavity. The filter assembly is rotatably mounted on the mounting frame and located in the mounting cavity. The filter assembly includes a filter frame, support rods, and a filter screen. The filter frame is arranged in a ring and extends laterally in the mounting cavity, with one end higher than the other, and the higher end of the filter frame located next to the inlet. The support rods extend laterally at both ends of the filter frame, and there are multiple support rods arranged in a ring. Each support rod is inclined on the filter frame, and all the rods are inclined in the same direction. The filter screen covers the outside of the filter frame and the support rods.

[0007] As a preferred embodiment, the water outlet is located at the bottom of the mounting cavity.

[0008] As a preferred embodiment, the mounting bracket is provided with a protective cover that covers the upper opening of the mounting cavity, and the water inlet is located on the protective cover.

[0009] As a preferred embodiment, the mounting frame is provided with two connecting parts arranged horizontally at intervals, the two connecting parts being one high and one low, and the filter frame is provided with a connecting shaft, the two ends of which are rotatably connected to the corresponding connecting parts.

[0010] As a preferred embodiment, each connecting part is provided with a bearing that mates with the connecting shaft.

[0011] As a preferred embodiment, the water inlet is located to the left or right of the connecting shaft.

[0012] As a preferred embodiment, the mounting frame has a discharge port that communicates with the mounting cavity, and the discharge port is located at the lower end of the filter frame.

[0013] As a preferred embodiment, the mounting frame is provided with an inclined guide plate, which is located on the side of the discharge port.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] The filter frame is horizontally extended within the mounting cavity, with one end higher than the other. Multiple ring-shaped support rods are attached, each inclined on the filter frame. All the rods tilt in the same direction, allowing wastewater to enter the filter frame from the outside and fall onto the support rods under gravity. The force exerted by the wastewater on the support rods drives the filter frame to rotate, eliminating the need for an external power source. This simplifies the structure and reduces operating costs. Furthermore, the inclined mounting frame allows wastewater to flow downwards along the support rods, increasing the flow distance compared to horizontal rotation. This results in better filtration and flushes away residual waste, preventing accumulation and ensuring optimal filtration.

[0030] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a mounting bracket 10 and a filter assembly 20.

[0031] The mounting frame 10 has a mounting cavity 101, and an inlet 102 and an outlet 103 respectively communicating with the mounting cavity 101. External wastewater enters the mounting cavity 101 and the filter assembly 20 through the inlet 102, and the outlet 103 is used to discharge the filtered wastewater for subsequent treatment processes. The outlet 103 is located at the bottom of the mounting cavity 101 to prevent filtered wastewater from remaining in the mounting cavity 101. A protective cover 11 is provided on the mounting frame 10, covering the upper opening of the mounting cavity 101. The inlet 102 is located on the protective cover 11. The protective cover 11 not only protects the filter assembly 20 but also prevents external dust from falling onto the surface of the filter assembly 20 and affecting its filtration effect. The mounting frame 10 has two horizontally spaced connecting parts 12, one higher than the other. The mounting frame 10 has a discharge port 104 that communicates with the mounting cavity 101. The discharge port 104 is used to discharge the filtered waste residue. The mounting frame 10 is provided with an inclined guide plate 14, which is located next to the discharge port 104. The guide plate 14 is used to facilitate the outward conveying of the waste residue.

[0032] The filter assembly 20 is rotatably mounted on the mounting frame 10 and located in the mounting cavity 101. The filter assembly 20 includes a filter frame 21, support rods 22, and a filter screen 23. The filter frame 21 is arranged in a ring and extends laterally in the mounting cavity 101, with one end of the filter frame 21 being higher than the other. The higher end of the filter frame 21 is located next to the inlet 102. The support rods 22 extend laterally at both ends of the filter frame 21, and there are multiple support rods arranged in a ring. Each support rod 22 is inclined on the filter frame 21, and all the support rods 22 are inclined in the same direction. The filter screen 23 covers the outside of the filter frame 21 and the support rods 22. Wastewater entering the filter assembly 20 is filtered out by the filter screen 23. In this embodiment, the filter frame 21 is provided with a connecting shaft 211, and the two ends of the connecting shaft 211 are rotatably connected to the corresponding connecting parts 12, thereby realizing the one end of the filter frame 21 being higher than the other. Each connecting part 12 is equipped with a bearing 13 that mates with the connecting shaft 211. The bearing 13 ensures smoother rotation of the filter frame 21, further guaranteeing the filtration effect. The water inlet 102 is located to the left or right of the connecting shaft. The position of the water inlet 102 can be adaptively set to the left or right of the connecting shaft according to the inclination direction of the support rod 22, making it easier for the gravity of the wastewater to act on the support rod 22 and drive the filter frame 21 to rotate. The discharge port 104 is located at the lower end of the filter frame 21.

[0033] The key design feature of this invention is that the filter frame extends laterally within the mounting cavity, with one end higher than the other. Multiple ring-shaped support rods are used, each inclined on the filter frame, all tilted in the same direction. This allows wastewater entering the filter frame from the outside to fall onto the support rods under gravity. The inclined frame and support rods, combined with the force exerted by the wastewater on the support rods, drive the filter frame to rotate, eliminating the need for an external power source. This simplifies the structure and reduces operating costs. Furthermore, the inclined mounting frame allows wastewater to flow downwards along the support rods, increasing the flow distance compared to horizontal rotation. This results in better filtration and flushes away residual waste, preventing accumulation and ensuring optimal filtration.

[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
