Abstract
Description
Technical Field
[0001] This utility model relates to a plate centrifuge, and more particularly to a plate centrifuge suitable for the immobilization and preparation of liquid lipase. Background Technology
[0002] Flatbed centrifuges utilize advanced centrifugation technology, generating powerful centrifugal force through high-speed rotation to rapidly separate different components in a mixture. Existing flatbed centrifuges have two main problems: First, the drain hole at the bottom of the centrifuge drum requires manual collection of the material inside. Since immobilized liquid lipases easily adhere to the inner wall of the drum, collection is difficult and inefficient. Second, the material is fed into the drum via a single feed pipe. Because the feed pipe is located in one position, the material is initially unevenly distributed within the drum, leading to uneven weight distribution and stress distribution. This reduces sample throughput and affects the effectiveness and efficiency of liquid lipase immobilization. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a flat plate centrifuge with reasonable design, high material collection efficiency, uniform material distribution, and suitable for the preparation of liquid lipase immobilization, in order to overcome the shortcomings of the existing technology.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A plate centrifuge suitable for the immobilization and preparation of liquid lipase includes a base, a drum mounted on the base, an outer shell covering the drum, and a cover plate on the top of the outer shell. A feed pipe extending into the drum is provided on the cover plate. A drain outlet is provided at the bottom of the outer shell, and a drain valve is installed at the drain outlet. The centrifuge is characterized by having a cloth bag inside the drum for easy material collection. The top of the cloth bag has a large opening the same size as the top opening of the drum, which is mounted at the top opening of the drum via a lifting frame. The bottom of the cloth bag has a small opening the same size as the central axis of the drum, and a tension rope is provided at the small opening for easy tightening.
[0006] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the lifting frame includes an annular plate with the same size as the top opening of the drum, a vertical baffle is provided on the top of the annular plate, the annular plate inside the vertical baffle is provided with an inner edge, an elastic ring for fixing the large opening of the cloth bag is provided on the inner edge, and a hydraulic cylinder connected to the annular plate is provided on the outer wall of the drum.
[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: at least three hydraulic cylinders are provided and are evenly arranged along the circumference of the drum.
[0008] The technical problem to be solved by this utility model can also be achieved by the following technical solution: a shock-absorbing component is provided at the bottom of the base.
[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the shock absorption component includes a fixed cylinder fixed on the ground and a spring provided in the fixed cylinder. A corrugated pipe for providing lifting stroke is fixed to the top of the fixed cylinder by a clamp. The upper end of the corrugated pipe is fixedly connected to a support provided at the bottom of the base by a clamp.
[0010] The technical problem to be solved by this utility model can also be achieved by the following technical solution: a material distributor is provided on the cover plate to achieve uniform material distribution inside the drum. The material distributor is provided with a material distribution pipe extending into the drum. The lower part of the material distribution pipe is provided with a bent pipe with its opening facing the feed pipe. A blower communicating with the material distribution pipe is installed on the cover plate. A one-way valve is installed on the material distribution pipe to prevent liquid backflow inside the drum.
[0011] Compared with existing technologies, this utility model features a filter bag for both material collection and filtration. The bag has openings at the top and bottom of different sizes. The top opening matches the top opening of the drum, while the bottom opening matches the diameter of the central rotating shaft of the drum. This allows for rapid collection of liquid lipase after fixation. Simultaneously, the filter bag has a filtration function, resulting in excellent material collection. Furthermore, the use of a material distribution pipe and air blowing for material distribution prevents material from accumulating in one location, thus reducing processing capacity. This design is convenient to use and increases the material processing capacity. Attached Figure Description
