Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater sludge-liquid separation equipment, specifically an industrial wastewater sludge-liquid separation equipment. Background Technology

[0002] Industrial production processes, such as metallurgy, chemical engineering, and food processing, generate large amounts of industrial wastewater containing solid particles. Direct discharge of this wastewater not only causes serious environmental pollution but also leads to a waste of water resources.

[0003] Existing industrial wastewater solid-liquid separation methods rely on external force to improve solid-liquid separation efficiency. However, the extrusion mechanism lacks a stable guiding structure, resulting in uneven pressure distribution and insufficient extrusion of solid and liquid in some areas, leading to incomplete solid-liquid separation and a high water content in the separated waste residue. Relying on a single extrusion or filtration structure cannot effectively intercept fine suspended solids, making it difficult to guarantee the purity of the effluent, thus requiring additional filtration processes. Furthermore, most separation equipment does not consider the deposition of fine particles in the separated liquid. These particles tend to accumulate at the bottom of the equipment and in the conveying channels, which can easily cause channel blockage with long-term use, further affecting the continuity and stability of the separation process.

[0004] Therefore, a new type of industrial wastewater sludge-liquid separation equipment needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an industrial wastewater sludge-liquid separation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial wastewater sludge-liquid separation device, comprising a cabinet, two inlet pipes on both sides of the cabinet, a cavity inside the cabinet, a cylinder on the top of the cabinet, a pressure plate at one end of the cylinder via a piston rod, four telescopic rods between the pressure plate and the cabinet, and a collection assembly in the center of the cabinet.

[0007] Preferably, the collection component includes two sliding rails, which are symmetrically arranged on the inner wall of the cabinet. A collection drawer is slidably connected to the sliding rails. The bottom of the collection drawer is provided with multiple through holes, which are arranged in a circular distribution. The pressure plate matches the size of the collection drawer.

[0008] Preferably, the bottom of the collection drawer is provided with an arc-shaped guide plate, the interior of which is provided with a metal filter plate, and the bottom of the cabinet is provided with a stirring component.

[0009] Preferably, the stirring assembly includes a drive motor, the output end of which is connected to a rotating shaft via a coupling, the cabinet is equipped with a stirring tank located at the bottom of the arc-shaped guide plate, the rotating shaft extends through the cabinet into the stirring tank, and the rotating shaft is equipped with multiple stirring rods.

[0010] Preferably, the bottom of the cabinet is provided with two water outlet pipes, and the water outlet pipes are equipped with shut-off valves.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a pressure plate driven by a cylinder and guided by a telescopic rod works in conjunction with a collection drawer with through holes at the bottom to apply efficient mechanical extrusion to the wastewater and sludge, achieving initial solid-liquid separation. The arc-shaped guide plate and built-in metal filter plate at the bottom of the collection drawer constitute a secondary filter, effectively intercepting fine suspended solids and improving the purity of the effluent. At the same time, the trapezoidal stirring rod in the bottom stirring tank continuously stirs the liquid under the drive of the motor, preventing the deposition of fine particles and clogging of the channels, ensuring the continuity and stability of the separation process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] All electronic components in this application are controlled by an external controller.

[0020] Example 1 Please refer to Figure 1-5 As shown, this utility model provides an industrial wastewater sludge-liquid separation device, including a cabinet 1. Two inlet pipes 2 are provided on both sides of the cabinet 1 for introducing the industrial wastewater sludge-liquid to be treated into the cabinet 1. The cabinet 1 has an internal cavity, and a cylinder 3 is located at the top of the cabinet 1. One end of the cylinder 3 is connected to a pressure plate 5 via a piston rod 4. The cylinder 3 drives the piston rod 4 to move linearly via air pressure, thereby causing the pressure plate 5 to move up and down. The size of the pressure plate 5 matches the size of the collection drawer 8. Under the action of the piston rod 4, the pressure plate 5 squeezes the sludge-liquid inside the collection drawer 8 downwards, achieving initial solid-liquid separation through pressure. Four telescopic rods 6 are provided between the pressure plate 5 and the cabinet 1. The two ends of the telescopic rods 6 are fixedly connected to the pressure plate 5 and the cabinet 1 respectively, to stabilize the movement trajectory of the pressure plate 5 and prevent deviation during downward pressure. A collection assembly is located in the center of the cabinet 1.

[0021] Specifically, the collection component includes two sliding rails 7, which are symmetrically arranged on the inner wall of the cabinet 1 to provide sliding tracks for the collection drawer 8, making it easy to pull out the collection drawer 8 to clean up waste residue. The collection drawer 8 is slidably connected to the sliding rails 7. The bottom of the collection drawer 8 is provided with multiple through holes 9, which are arranged in a circular pattern. The collection drawer 8 can receive the waste residue liquid from the sewage inlet pipe 2. Under the pressure applied by the pressure plate 5, the through holes 9 at the bottom of the collection drawer 8 allow the liquid in the waste residue to flow out smoothly and intercept the waste residue. The size of the pressure plate 5 matches that of the collection drawer 8.

[0022] The bottom of the collection drawer 8 is provided with an arc-shaped guide plate 10 to guide the filtered liquid to flow into the mixing tank 14 below, avoiding liquid splashing or stagnation; the arc-shaped guide plate 10 is provided with a metal filter plate 11 inside, which is built into the arc-shaped guide plate 10 to perform secondary filtration on the permeated liquid, intercepting fine suspended impurities and improving the purity of the liquid; the bottom of the cabinet 1 is provided with a stirring component.

[0023] Based on the above embodiments, specifically, the stirring assembly includes a drive motor 12, which is fixedly connected to the bottom of the cabinet 1 by bolts to provide rotational power for the stirring assembly; the output end of the drive motor 12 is connected to a rotating shaft 13 via a coupling, and the rotating shaft 13 transmits the rotational power of the drive motor 12 to the stirring rod 15, causing the stirring rod 15 to rotate synchronously; the cabinet 1 is equipped with a stirring tank 14 inside, which is located at the bottom of the arc-shaped guide plate 10. The stirring tank 14 is open, and the arc-shaped guide plate 10 is provided above the opening for storing the liquid that has been initially filtered; the rotating shaft 13 extends through the cabinet 1 into the stirring tank 14, and multiple stirring rods 15 are provided on the rotating shaft 13. The stirring rods 15 are trapezoidal in design and are used to stir the liquid to prevent the deposition of fine waste residue, avoid clogging the subsequent channels, and improve the thoroughness of residue-liquid separation.

[0024] Specifically, the bottom of the cabinet 1 is provided with two water outlet pipes 16 for discharging the liquid after separation treatment; the water outlet pipe 16 is provided with a shut-off valve 17, which is installed on the water outlet pipe 16 to control the opening and closing of the water outlet pipe 16 and adjust the drainage speed.

[0025] Working principle: During operation, wastewater and sludge enter the cavity inside the cabinet 1 through the sewage inlet pipes 2 on both sides and flow directly into the collection drawer 8. Large pieces of waste residue and sludge are blocked by the through hole 9. Then, the cylinder 3 at the top of the cabinet 1 drives the pressure plate 5 to move downward. Under the stable guidance of the four telescopic rods 6, the sludge and liquid in the collection drawer 8 are squeezed to achieve initial solid-liquid separation. The liquid flows out through the through hole 9 at the bottom of the drawer, while the waste residue is intercepted.

[0026] The separated liquid passes through the arc-shaped guide plate 10 at the bottom of the collection drawer 8. The metal filter plate built into the arc-shaped guide plate 10 performs secondary filtration and is then guided by the arc-shaped guide plate 10 into the mixing tank 14 at the bottom. At the same time, the drive motor 12 drives the stirring rod 15 to rotate continuously through the rotating shaft 13, stirring the liquid in the tank to prevent fine particles from settling and clogging. Finally, the clarified liquid, after thorough separation and stirring, is discharged from the drain pipe 16 at the bottom of the cabinet 1 under the shut-off valve 17.
