Description
Technical Field
[0001] This utility model belongs to the field of oyster meat processing and filtration technology, and in particular relates to a multi-stage precision filtration device for oyster meat production. Background Technology
[0002] In the production of oyster sauce and oyster meat seasonings, the efficient extraction of pure oyster juice from oyster paste is a key technological step. Traditional filtration methods often use static screens or rely on gravity for natural percolation, resulting in low filtration efficiency and limited processing capacity. Oyster paste has a viscous texture and fine solid particles, which easily clog the filter screen pores, leading to slow filtration speed, frequent shutdowns for cleaning, and difficulty in achieving complete solid-liquid phase separation, resulting in a loss of oyster juice yield. At the same time, in the later stages of filtration, due to the accumulation of filter cake and the lack of effective separation driving force, the effective components remaining in the residue phase are difficult to fully recover. This extensive filtration method restricts the continuity and automation level of production and has become a major bottleneck in improving product quality and yield.
[0003] To address these issues, we provide a multi-stage precision filtration device for oyster meat production. Utility Model Content

A base cover is fixedly installed inside the vertical wall below the cone shell. A centrifugal cone is fixed at the center of the upper end face of the base cover, and a fine filter paper ring is fitted around the centrifugal cone. A coarse filter component is installed above the cone shell. After the oyster meat is processed into minced meat, it is filtered by the coarse filter component, extracting the oyster juice from the oyster meat. The oyster juice enters the cone shell, and a motor drives the cone shell to rotate. Under the action of centrifugal force, the oyster juice on the base cover passes through the fine filter paper ring inside the cone shell and enters the collection funnel through the liquid permeation holes on the surface of the base cover plate. This completes the multi-stage filtration of the oyster meat and the extraction of the oyster juice.

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Example 1 Please see Figures 1 to 5This utility model relates to a multi-stage precision filtration device for oyster meat production, comprising a coarse filtration component 1, a fine filtration component 2, and a platform 3. The fine filtration component 2 includes a conical shell 201, a bottom cover 202, a fine filter paper ring 203, and a liquid collection funnel 204. A vertical wall 201a is fixedly provided on the lower end face of the conical shell 201. The bottom cover 202 is fixedly fitted inside the vertical wall 201a. A centrifugal cone 202a is fixedly provided at the center of the upper end face of the bottom cover 202. A set of liquid permeation holes 202b are circumferentially arrayed on the surface of the bottom cover 202. The fine filter paper ring 203 is positioned above the liquid permeation holes 202b. The conical shell 201 is rotatably mounted on the surface of the platform 3. The outer wall of the vertical wall 201a is connected to the motor via a connecting belt. The output end is connected to the drive, and the lower end of the bottom cover 202 passes through the platform 3. The liquid collection funnel 204 is fixedly installed on the lower end face of the bottom cover 202. The upper end of the cone of the cone shell 201 is fixed with the liquid inlet pipe head 201b. The coarse filter component 1 is set above the cone shell 201, and the outlet end of the coarse filter component 1 is connected to the liquid inlet pipe head 201b. The rotating cone shell 201 and the fine filter component 2 with the built-in centrifugal cone 202a make the oyster juice after coarse filtration forced to pass through the fine filter paper ring 203 under the action of centrifugal force, realizing a dynamic and efficient fine filtration process. This effectively overcomes the problems of filter screen clogging and low efficiency caused by the viscosity and fine particles of traditional static filtration, significantly improves the filtration speed and processing capacity, and ensures the continuity of production.
[0022] Specifically, the upper and lower ends of the outer side wall of the vertical wall 201a are respectively fixed with a sleeve edge 201a-1, and a set of ball bearing seats 201a-2 are fixed on the lower end face of the lower sleeve edge 201a-1. Ball bearings 201a-3 are fixedly embedded in the lower end face of the ball bearing seats 201a-2. A ball bearing ring groove 301 is opened on the upper end face of the platform 3. Each ball bearing 201a-3 is rolled and embedded in the ball bearing ring groove 301. The rolling cooperation between the ball bearings 201a-3 and the ball bearing ring groove 301 provides stable and low-friction support for the rotation of the cone shell 201, ensuring the stability and reliability of the equipment when operating at high speed, reducing vibration and noise, reducing transmission energy consumption, and extending the service life of the equipment.
[0023] Furthermore, a filter paper ring holder 202c is provided on the upper end face of the bottom cover 202. The inner ring wall of the filter paper ring holder 202c is sleeved on the outer side of the centrifugal cone 202a, and the outer wall of the filter paper ring holder 202c is attached to the upper inner cover wall of the bottom cover 202. A set of through holes 202c-1 are opened through the plate surface of the filter paper ring holder 202c, and the fine filter paper ring 203 is attached to the upper end face of the filter paper ring holder 202c. The filter paper ring holder 202c not only provides a stable installation platform for the fine filter paper ring 203, preventing it from shifting or deforming under the action of centrifugal force, but also ensures that the filtrate passes smoothly through the through holes 202c-1. At the same time, the design of the centrifugal cone 202a helps to guide the oyster juice to be evenly distributed, avoid local accumulation, and improve the uniformity of filtration and the utilization rate of the fine filter paper ring 203.
[0024] Furthermore, the coarse filtration component 1 includes a filter cake assembly 101 and a pressurizing assembly 102. The filter cake assembly 101 includes a coarse filter screen cylinder 101a, a filter cloth sleeve 101b, a screen cylinder end cap 101c, and a liquid collection tube sleeve 101d. An L-shaped mounting arm 101d-1 is fixedly provided on the outer wall of the liquid collection tube sleeve 101d. The lower end of the mounting arm 101d-1 is fixedly mounted on the upper end plate surface of the platform 3. The filter cloth sleeve 101b is sleeved inside the coarse filter screen cylinder 101a. The screen cylinder end cap 101c is installed at the upper opening of the coarse filter screen cylinder 101a. The liquid collection tube sleeve 101d... The pressure assembly 102 is detachably fitted onto the lower outer side of the end cap 101c of the filter cylinder and is located inside the filter cloth sleeve 101b. The lower end of the liquid collection tube sleeve 101d is fitted inside the liquid inlet head 201b. The cooperation between the filter cloth sleeve 101b and the coarse filter cylinder 101a achieves preliminary solid-liquid separation. The detachable liquid collection tube sleeve 101d is easy to clean and maintain. The introduction of the pressure assembly 102 provides an active driving force for the coarse filtration process, effectively accelerating the initial extraction of oyster juice, reducing material retention, laying the foundation for subsequent fine filtration, and improving the overall filtration efficiency.
[0025] Furthermore, the pressurizing assembly 102 includes a filter press piston 102a, a compression spring 102b, and a top spring plug 102c. A sliding sleeve 101c-1 is vertically fixed to the upper end face of the mesh cylinder end cap 101c. The filter press piston 102a is slidably sleeved inside the filter cloth sleeve 101b. The compression spring 102b is fixedly connected to the upper end face of the filter press piston 102a. The top spring plug 102c is vertically slidably sleeved inside the sliding sleeve 101c-1. The upper end of the compression spring 102b is fixedly connected to the lower end face of the top spring plug 102c. The elastic force of the compression spring 102b continuously pushes the filter press piston 102a downward, applying uniform and stable pressure to the oyster meat paste, forcing the oyster juice through the filter cloth sleeve 101b, which significantly improves the juice extraction efficiency and thoroughness of the coarse filtration stage and avoids filtration stagnation or blockage caused by the viscosity of the material.
[0026] Furthermore, the upper closed section of the sliding sleeve 101c-1 is threaded with a downward pressure screw 102c-1, the lower end of which rests against the upper end face of the top spring plug 102c. The downward pressure screw 102c-1 allows the user to adjust the downward pressure on the top spring plug 102c by rotation, precisely controlling the compression amount of the compression spring 102b, and achieving stepless adjustment of the coarse filtration pressure. This enables the device to adapt to oyster meat paste raw materials with different viscosities or moisture contents, enhancing the process adaptability and operational flexibility of the equipment, and further optimizing the coarse filtration effect.
[0027] The operation process in this embodiment is as follows: First, the oyster meat mince is placed into the filter cloth sleeve 101b of the coarse filter component 1, the screen cylinder end cap 101c is installed, and the liquid collection tube sleeve 101d is connected to the liquid inlet pipe head 201b. Then, according to the material characteristics, the pressure of the pressurizing component 102 is adjusted by rotating the pressing screw 102c-1. The compression spring 102b pushes the filter press piston 102a down, causing the oyster juice to initially separate from the mince and flow into the collection tube through the filter cloth sleeve 101b and the coarse filter cylinder 101a. Liquid tube sleeve 101d; the oyster juice that has been initially filtered enters the rotating conical shell 201 through the liquid inlet head 201b. The motor drives the conical shell 201 to rotate at high speed through the belt. Under the action of centrifugal force, the oyster juice moves towards the peripheral wall and passes through the fine filter paper ring 203 for fine filtration. Solid particles are trapped, and the pure oyster juice falls into the liquid collection funnel 204 through the liquid permeation hole 202b on the bottom cover 202 for collection. After use, the motor is turned off, and each filter element and component can be disassembled and cleaned for the next use.
