Description

Technical Field

[0001] This utility model relates to the field of anaerobic tank reaction mixture separation technology, specifically a countercurrent three-phase separator for anaerobic tanks. Background Technology

[0002] In fields such as wastewater treatment and organic waste resource utilization, anaerobic digesters, as core reaction equipment, require three-phase separators to achieve efficient separation of the gas, liquid, and solid phases in the reaction mixture, in order to ensure the stable operation of the anaerobic digestion process and improve treatment efficiency and resource recovery rate.

[0003] Currently, most anaerobic three-phase separators on the market adopt the basic structure of filter plates to retain solid phase and baffle plates to separate gas and liquid. However, there are still many shortcomings in practical applications. After long-term use, the surface and filter holes of the filter plates of traditional three-phase separators are easily blocked by solid materials such as sludge. The equipment needs to be disassembled manually for cleaning, which is not only labor-intensive and inefficient, but also causes equipment downtime and affects the continuity of the overall treatment process. Some equipment with unblocking function has a simple unblocking mechanism design with limited cleaning coverage, making it difficult to completely remove stubborn sludge in the filter holes. In addition, there is a lack of auxiliary unblocking methods, resulting in poor unblocking effect.

[0004] Meanwhile, the existing three-phase separators have insufficient optimization of gas-liquid separation structure, unreasonable baffle angle design, and lack of auxiliary structures to enhance separation, resulting in a short gas-liquid separation path, poor inertial collision effect, and problems of incomplete gas-liquid separation and low separation efficiency, which affect the quality of subsequent material recovery. Against this background, we propose a countercurrent three-phase separator for anaerobic ponds. Utility Model Content

[0005] The purpose of this utility model is to provide a countercurrent three-phase separator for anaerobic ponds. By setting up filter plates, staggered baffles and collision blocks, it solves the problems of incomplete gas-liquid-solid separation and low efficiency in traditional three-phase separators. By setting up a cleaning mechanism and heating strips, it solves the problems of easy clogging of filter plates, cumbersome manual cleaning and impact on equipment operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A countercurrent three-phase separator for an anaerobic digester includes a base plate, a separation cylinder mounted on the top surface of the base plate, a detachable cover mounted on the top surface of the separation cylinder, a plurality of baffles for separating liquid phase materials mounted on the inner wall of the separation cylinder, and a filter plate for separating solid phase materials mounted near the bottom of the separation cylinder. The separator also includes: A cleaning mechanism, located inside the separation cylinder, is used to clean the solid material on the surface of the filter plate. The cleaning mechanism includes a movable rod slidably connected to the inner wall of the separation cylinder, a lifting plate located below the filter plate, several brush bristles fixed on the top surface of the lifting plate, an electric push rod installed on the outer wall of the movable rod for driving the lifting plate to move up and down, a screw rotatably connected to the inner wall of the separation cylinder for driving the movable rod to move left and right, and a motor installed on the outer wall of the separation cylinder for driving the screw to rotate.

The motor is mounted on the outer wall of the separation cylinder, and the output shaft of the motor is coaxially connected to the rotating column on the same side. The screw is coaxially fixed between the two rotating columns and is arranged laterally, and the screw is threadedly connected to the moving rod.

The longitudinal cross-sectional shape of the guide grooves on the inner wall of the separation cylinder is I-shaped, and the shape of the guide blocks is I-shaped to match the shape of the guide grooves on the inner wall of the separation cylinder. In one preferred embodiment, the bristles on the top surface of the lifting plate are arranged in a matrix, and the positions of the filter plate and the bristles are corresponding and their sizes are matched. These four settings make the lifting plate's lifting transmission smoother, reduce direct wear between the piston rod and the lifting plate, stabilize the lateral drive of the moving rod, ensure the operational reliability of the cleaning mechanism, ensure precise and non-deviation-free sliding of the moving rod, improve the working accuracy of the cleaning mechanism, ensure comprehensive cleaning coverage of the filter plate, and improve the filter plate unclogging effect.

[0008] In a preferred embodiment, several baffles are fixed in two groups on the inner walls of the left and right sides of the separation cylinder, respectively. The two groups of baffles are staggered. Each group of baffles is installed on the inner wall of the separation cylinder in a vertical linear and equidistant arrangement. Several baffles on the left side extend to the right, and several baffles on the right side extend to the left. An S-shaped baffle channel is formed between every two adjacent baffles. The inclination angle of the baffles is 25°-47°, and several collision blocks arranged in a matrix are fixed on the bottom surface of the baffles. In a preferred embodiment, the separation cylinder is fixed to the top surface of the base plate by several support legs. The top surface of the base plate is provided with several mounting holes.

A water outlet pipe communicating with the inner cavity is fixed to the bottom end of the separation cylinder. Manual valves are installed on the outer walls of both the water outlet pipe and the air outlet pipe.

The air outlet pipe passes through the top surface of the sealing plate and extends into the interior of the separation cylinder near the top.

They also make the cylinder cover easy to install and remove, ensure good device sealing, prevent gas-liquid leakage, and guarantee a stable separation environment.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves efficient and opposite-directional separation of gas, liquid, and solid phases through the coordinated arrangement of a separation cylinder, filter plates, staggered baffles, and collision blocks. The feed mixture first passes through the filter plates to retain solid sludge, and then the liquid and gas mixture enters the S-shaped baffle channel. With the help of the inclined angle of the baffles and the bottom collision blocks, the inertial collision separation of gas and liquid is enhanced. Finally, the gas phase is collected through the gas outlet pipe, and the liquid phase is discharged from the water outlet pipe. This design precisely matches the separation requirements of anaerobic reaction, greatly improves the separation efficiency and material purity, and lays the foundation for subsequent treatment or resource recovery. 2. This utility model achieves automated anti-clogging and cleaning of filter plates through the combination of a cleaning mechanism and a heating strip. The motor-driven screw drives the moving rod to slide laterally, and the electric push rod pushes the lifting plate upward, allowing the matrix-style bristles to penetrate deep into the filter plate pores for cleaning. The I-shaped guide block ensures stable movement. The heating strip helps soften stubborn sludge, and with the detachable cylinder cover and sealing structure, cleaning can be completed without manual disassembly. This design completely solves the problem of easy clogging of traditional filter plates, reduces the number of equipment downtime maintenance, lowers labor costs, and at the same time ensures the long-term stable operation of the separation system and extends the service life of the equipment.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

The cleaning mechanism 3 includes a movable rod 31 slidably connected to the inner wall of the separation cylinder 2, a lifting plate 32 located below the filter plate 210, several bristles 34 fixed on the top surface of the lifting plate 32, an electric push rod 33 installed on the outer wall of the movable rod 31 and used to drive the lifting plate 32 to move up and down, a screw 36 rotatably connected to the inner wall of the separation cylinder 2 and used to drive the movable rod 31 to move left and right, and a motor 37 installed on the outer wall of the separation cylinder 2 and used to drive the screw 36 to rotate. By combining the base plate 1, separation cylinder 2, cylinder cover 22, baffle plate 27, filter plate 210 and cleaning mechanism 3, the device can achieve heterogeneous separation of gas, liquid and solid phases, and can automatically clean the filter plate 210 without manual disassembly and clogging, greatly improving ease of use.

By using the electric push rod 33 and the shim 39, the lifting plate 32 is subjected to uniform force, and the lifting action is smooth.
