Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to a modular solid-liquid separation device. Background Art

[0002] As an indispensable device in the industrial production process, the solid-liquid separation system is widely used in industries such as chemical engineering, pharmaceuticals, food, and environmental protection. Its main function is to separate solid particles or crystals from the liquid medium, thereby realizing resource recovery and product purification. Through an efficient separation process, these systems can not only improve production efficiency but also reduce waste generation, promoting green production.

[0003] With the continuous development of industrial production, the limitations of traditional solid-liquid separation systems have gradually emerged. First of all, the transportation problem is a major challenge in system deployment. Since existing solid-liquid separation systems usually consist of multiple components, these components need to be transported to the production site and then assembled. This process not only takes time and effort but also places high requirements on the assembly ability of technicians, resulting in a slow overall assembly speed.

[0004] Secondly, large floor space and cumbersome on-site deployment are also problems faced by solid-liquid separation systems. The system often requires complex wiring and adjustment on-site, affecting the utilization efficiency of the production site. In addition, the system has weak transfer capabilities and cannot flexibly respond to changes in production tasks, resulting in poor overall flexibility and affecting the production efficiency and market competitiveness of enterprises.

[0005] Finally, the cost of existing solid-liquid separation systems is relatively high, including equipment cost, transportation cost, assembly cost, and maintenance cost. These high costs pose great pressure on some small and medium-sized enterprises when choosing and applying such equipment, restricting the popularization and application of modular solid-liquid separation systems.

[0006] Therefore, existing solid-liquid separation systems need to be further optimized and improved. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a modular solid-liquid separation device that is superior to existing devices in terms of transportation, assembly, space occupation, transfer ability, and cost.

[0008] To achieve the above purpose, the utility model adopts the following scheme: A modular solid-liquid separation device, comprising:

[0009] A frame, which is rectangular in shape;

[0010] A mother liquor tank, and the mother liquor tank is installed within the frame;

[0011] A centrifuge installed at the top of the frame, which is used to receive the concentrated liquid from the external crystallization system, perform solid-liquid separation on it, and is driven by a drive motor installed on one side of the centrifuge;

[0012] A liquid discharge pipe, the two ends of which are respectively connected between the bottom of the centrifuge and the top of the mother liquor tank, and is used to introduce the separated liquid into the mother liquor tank;

[0013] A drain pipe, which is connected to the bottom of the mother liquor tank and is used to transport the liquid in the mother liquor tank back to the external crystallization system for recycling;

[0014] A hopper, which is installed at the top of the frame and opens downward, and is used to discharge the solid particles separated by the centrifuge.

[0015] The above solution integrates the mother liquor tank, centrifuge and other components within a rectangular frame. Through this modular design, the structure of the equipment is compact and the overall deployment is simple and convenient. Compared with the traditional solid-liquid separation system, the modular frame makes the transportation and installation of the equipment more simple and fast, greatly shortening the assembly time and reducing the complexity of on-site deployment. In addition, the modular structure also helps to save space and improve the site utilization rate. In addition, by directly connecting the centrifuge and the mother liquor tank, the liquid after solid-liquid separation can quickly enter the mother liquor tank, reducing the intermediate links. This design not only improves the separation efficiency, but also simplifies the pipeline layout and reduces the risk of pipeline failures. At the same time, the entire separation process is more smooth, reducing the operation difficulty and maintenance cost, and enhancing the stability and operation efficiency of the system.

The design of the blanking port corresponding to the hopper ensures the smooth discharge of solid particles. The overall layout is simple, reducing the possibility of particle blockage, and at the same time optimizing the material flow path and improving the separation efficiency.

[0020] As a preferred embodiment of the present utility model, a liquid extraction pump is provided on the drain pipe, and a check valve is provided at the liquid outlet end of the drain pipe. By providing a liquid extraction pump and a check valve on the drain pipe, the flow of the liquid can be effectively controlled to prevent the liquid from flowing back or leaking.

[0022] As a further embodiment of the present utility model, a rain shelter is provided on the frame, which can cover the top of the frame and cover the centrifuge and the driving motor. This design provides effective protection for the centrifuge and the motor, especially suitable for working conditions outdoors or in harsh environments. The design of the rain shelter can extend the service life of the equipment, reduce equipment damage caused by environmental factors, reduce maintenance costs, and ensure the stable operation of the equipment under various weather conditions.

[0023] As a preferred embodiment of the present utility model, the centrifuge is a continuous filtration centrifuge. This makes the solid-liquid separation process more efficient and continuous, reducing the downtime and being suitable for large-scale industrial production.

[0026] In addition, the design of feeding at the top and discharging at the front end of the centrifuge, as well as the discharge channel corresponding to the hopper, ensure the smooth discharge of solid particles, facilitating the handling of solid particles by the operator.

[0037] The present utility model will be further described below in conjunction with the accompanying drawing description and the specific implementation mode: As Figures 1 to 5A modular solid-liquid separation device shown in the figure includes a rectangular frame 1. A tank base 11 is provided at the bottom of the frame 1. A mother liquor tank 2 is arranged inside the frame 1, and the bottom of the mother liquor tank 2 is installed on the tank base 11. A centrifuge 3 is installed at the top of the frame 1, which is used to receive the concentrated liquid from the external crystallization system and perform solid-liquid separation on it. In this embodiment, a continuous filtration centrifuge is used for the centrifuge 3. Compared with the traditional intermittent centrifuge, the continuous centrifuge not only improves the production efficiency, but also reduces the operation complexity and energy consumption, making the system operation more economical. A driving motor 4 for driving the centrifuge 3 to work is provided at the top of the frame 1 on one side of the centrifuge 3. A feed inlet 31 is provided at the top of the centrifuge 3 and is connected to the external crystallization system through a pipeline for inputting the concentrated liquid.

A receiving area 12 is provided at the bottom of the frame 1 below the outlet of the hopper 5, which facilitates the operator to bag the solid particles.

[0038] Among them, as Figures 1 to 4 shown, a through hole 20 is provided at the top of the mother liquor tank 2. A liquid outlet pipeline 33 is connected to the bottom of the centrifuge 3 for guiding the separated liquid into the mother liquor tank 2.

[0039] In addition, in order to keep the liquid in the mother liquor tank 2 uniform, precipitation is avoided, thereby improving the liquid recycling efficiency.

[0041] The working principle of the utility model is as follows: The concentrated liquid is first transported to the inside of the centrifuge 3 by the crystallization system through a pipeline. Driven by the motor 4, the centrifuge rotates at a high speed, generating a strong centrifugal force, which causes the solid particles in the liquid to settle rapidly and separate from the liquid. The separated solid particles are discharged through the discharge port 32 inside the centrifuge 3, directly falling into the hopper 5, and entering the prepared collection bag under the guidance of the hopper 5, facilitating subsequent processing and transportation.

[0042] Meanwhile, the liquid mother liquor separated by the centrifuge 3 flows into the lower mother liquor tank 2 by gravity through the liquid discharge pipeline 33 for centralized collection. The liquid in the mother liquor tank 2 is transported back to the crystallization system by the liquid extraction pump 21 through the connected liquid discharge pipeline 22 for the next round of recycling, thus realizing the efficient utilization of resources and closed-loop operation of the entire system. This process not only improves the efficiency of solid-liquid separation, but also reduces resource waste, enhancing the sustainability and economic benefits of production.
