Description

Technical Field

[0001] This utility model relates to the field of environmental engineering equipment technology, and more specifically, to an environmental engineering solid-liquid separation device. Background Technology

[0002] In the field of environmental engineering, solid-liquid separation is a crucial fundamental process, widely used in various stages such as wastewater treatment, industrial wastewater purification, and solid waste resource recovery. Its main purpose is to effectively separate solid and liquid substances in a mixed system, so as to achieve the purification and reuse of liquids and the further treatment or resource utilization of solids.

[0003] Based on the above, the inventors have discovered that traditional solid-liquid separation devices, such as sedimentation tanks and plate and frame filter presses, often have limitations in practical applications. For example, sedimentation tanks have low separation efficiency, large footprint, and poor separation effect on fine particles; plate and frame filter presses are relatively cumbersome to operate, the filter cloth is prone to clogging, requiring frequent cleaning and replacement, resulting in high maintenance costs. Furthermore, some solid-liquid separation devices are prone to incomplete separation, equipment clogging, and unstable throughput when processing materials containing high concentrations of suspended solids or high viscosity, making it difficult to meet the requirements of modern environmental engineering for efficient, energy-saving, and continuously stable operation. Therefore, in view of this, the inventors have researched and improved existing structures to provide a solid-liquid separation device for environmental engineering, aiming to achieve greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a solid-liquid separation device for environmental engineering. It can effectively solve the problems of low separation efficiency, large footprint, poor separation effect on fine particles, cumbersome operation, easy clogging of filter cloth, high maintenance cost, and incomplete separation, equipment blockage and unstable processing capacity when processing high-concentration suspended solids or highly viscous materials. This device can meet the requirements of modern environmental engineering for efficient, energy-saving and continuous stable operation of solid-liquid separation processes.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0006] An environmental engineering solid-liquid separation device includes a mounting frame. Two mounting seats are fixedly connected to one end of the mounting frame. An outer cylinder and an inner cylinder are fixedly connected between the two mounting seats, with the inner cylinder located inside the outer cylinder. A filter plate is fixedly connected inside the outer cylinder and located at the bottom end of the inner cylinder. A slag discharge cylinder is fixedly connected to the top of the outer cylinder. A transition sleeve is fixedly connected to the top of the slag discharge cylinder. A sealing cover is fixedly connected to the top of the transition sleeve. A rotating shaft is rotatably connected between the inner bottom wall of the outer cylinder and the bottom of the transition sleeve. A spiral blade is fixedly connected to the outer periphery of the rotating shaft. A driving mechanism is provided inside the sealing cover.

[0007] Furthermore, a waste inlet is fixedly installed on the bottom outer periphery of the inner cylinder, with one end of the waste inlet extending to the outside of the outer cylinder and the other end communicating with the inside of the inner cylinder.

[0008] Furthermore, the outer surface of the inner cylinder is provided with a number of filter holes, and the filter holes are evenly distributed.

[0009] Furthermore, the inner bottom of the outer cylinder is divided by a filter plate to form a liquid storage chamber, and a drain port is fixedly installed at the bottom of the outer cylinder and is connected to the liquid storage chamber. The outer periphery of the transition sleeve is fixed and connected to a slag discharge port.

[0010] Furthermore, the top and bottom of the inner cylinder are both open, the top of the inner cylinder is connected to the interior of the transition sleeve, and the bottom of the inner cylinder is connected to the liquid storage chamber.

[0011] Furthermore, the helical blade extends from the bottom of the inner cylinder into the transition sleeve, and the outer periphery of the helical blade is fitted and connected to the inner wall of the inner cylinder.

[0012] Furthermore, the drive mechanism includes a drive motor fixedly installed at the bottom of one end of the sealing cover. The output shaft of the drive motor extends into the interior of the sealing cover and is connected to the extended end of the rotating shaft via a pulley set.

[0013] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) This scheme sets up a double-layer structure of inner and outer cylinders and opens evenly distributed filter holes on the surface of the inner cylinder. With the drive mechanism driving the rotating shaft and spiral blades to rotate at high speed, the solid-liquid mixture entering the inner cylinder is subjected to centrifugal force. The liquid quickly passes through the filter holes into the space between the outer and inner cylinders, and after being filtered by the filter plate, it enters the liquid storage chamber and is discharged from the drain port. This achieves efficient separation and purification of the liquid and effectively solves the problem of poor separation effect of fine particles in traditional devices.

[0014] (2) In this scheme, by fitting the outer periphery of the spiral blades to the inner wall of the inner cylinder and the bottom of the spiral blades to the upper surface of the filter plate, the spiral blades can continuously push the solid material at the bottom of the inner cylinder upward during rotation. After passing through the slag discharge cylinder into the transition sleeve, the material is discharged from the slag discharge port, forming a continuous solid-liquid separation and slag discharge process. This can effectively reduce material residue, avoid clogging of the filter plate and the inner cylinder, reduce maintenance costs, and ensure stable processing capacity, thereby fully meeting the modern environmental engineering requirements for efficient, energy-saving, continuous and stable operation of solid-liquid separation processes.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figures 1-4An environmental engineering solid-liquid separation device includes a mounting frame 1. Two mounting seats 2 are fixedly connected to one end of the mounting frame 1. An outer cylinder 3 and an inner cylinder 4 are fixedly connected between the two mounting seats 2, and the inner cylinder 4 is located inside the outer cylinder 3. A filter plate 5 is fixedly connected inside the outer cylinder 3 and is located at the bottom end of the inner cylinder 4. A slag discharge cylinder 6 is fixedly connected to the top of the outer cylinder 3. A transition sleeve 7 is fixedly connected to the top of the slag discharge cylinder 6. A sealing cover 8 is fixedly connected to the top of the transition sleeve 7. A rotating shaft 9 is rotatably connected between the inner bottom wall of the outer cylinder 3 and the bottom of the transition sleeve 7. A spiral blade 10 is fixedly connected to the outer periphery of the rotating shaft 9. A driving mechanism 11 is provided inside the sealing cover 8.

[0019] See Figure 4 Waste inlet 12 is fixedly installed on the outer periphery of the bottom of the inner cylinder 4. One end of the waste inlet 12 extends to the outside of the outer cylinder 3, and the other end is connected to the inside of the inner cylinder 4.

[0020] See Figure 3 The outer surface of the inner cylinder 4 is provided with a number of filter holes 13, and the filter holes 13 are evenly distributed.

[0021] See Figure 3 and Figure 4 The bottom of the outer cylinder 3 is divided by the filter plate 5 to form a liquid storage chamber 301. A drain port 14 is fixedly installed at the bottom of the outer cylinder 3 and is connected to the liquid storage chamber 301. A slag discharge port 15 is fixed and connected to the outer periphery of the transition sleeve 7.

[0022] See Figure 4 The top and bottom of the inner cylinder 4 are open. The top of the inner cylinder 4 is connected to the inside of the transition sleeve 7, and the bottom of the inner cylinder 4 is connected to the liquid storage chamber 301.

[0023] See Figure 4 The spiral blade 10 extends from the bottom of the inner cylinder 4 into the transition sleeve 7, and the outer periphery of the spiral blade 10 is fitted and connected to the inner wall of the inner cylinder 4.

[0024] See Figure 3 The drive mechanism 11 includes a drive motor 1101 fixedly installed at the bottom of one end of the sealing cover 8. The output shaft of the drive motor 1101 extends into the interior of the sealing cover 8 and is connected to the extension end of the rotating shaft 9 via a pulley set 1102.

[0025] In use: First, the solid-liquid mixture to be treated is continuously pumped into the inner cylinder 4 through the waste inlet 12. Then, the drive mechanism 11 inside the sealing cover 8 is activated, and the drive motor 1101 starts working. Its output shaft drives the rotating shaft 9 to rotate at high speed via the pulley set 1102. The spiral blades 10 fixed to the outer circumference of the rotating shaft 9 rotate synchronously inside the inner cylinder 4. Under the action of centrifugal force, the liquid components in the inner cylinder 4 quickly pass through the numerous evenly distributed filter holes 13 and enter the space between the inner cylinder 4 and the outer cylinder 3. Next, this initially filtered liquid falls onto the filter plate 5 inside the outer cylinder 3, where the filter plate 5 performs further fine filtration to remove any remaining tiny solid particles. The filtered clean liquid permeates into the liquid storage chamber 301 formed at the bottom of the outer cylinder 3 below the filter plate 5 and is finally discharged through the drain port 14, allowing for direct reuse or subsequent processing. Meanwhile, the solid material trapped inside the inner cylinder 4 is continuously pushed upwards from the bottom of the inner cylinder 4 by the rotating spiral blades 10, which are in close contact with the inner wall of the inner cylinder 4 and with the bottom of the spiral blades 10 in contact with the upper surface of the filter plate 5. Under the pushing action of the spiral blades 10, the solid material gradually moves upwards, enters the slag discharge cylinder 6 through the opening at the top of the inner cylinder 4, then enters the transition sleeve 7, and finally, under the continuous conveying of the spiral blades 10, is continuously discharged from the slag discharge port 15 on the outer periphery of the transition sleeve 7, thus achieving continuous separation of the solid-liquid mixture. Throughout the process, the mounting frame 1 and the mounting base 2 provide stable support for the entire device, ensuring stable separation operation.
