Description

Technical Field

[0001] This utility model relates to the technical field of fish meat processing equipment, and in particular to a fish paste cleaning and fine filtration device. Background Technology

[0002] In the industrial production of surimi products, efficient removal of impurities such as bones and scales is a key step in ensuring product quality. Traditional surimi filtration processes have the following drawbacks: Incomplete cleaning: Static soaking or drum washing easily leads to surimi accumulation, resulting in low efficiency in separating bones from fish meat and a residual impurity rate of 3%-5%; High separation energy consumption: A single filter press requires multiple repeated compressions, increasing power consumption by more than 30%; Low automation: Feed flow rate depends on manual adjustment, and the coupling of vibration feeding and filter press actions can easily cause equipment resonance, increasing the failure rate.

[0003] Chinese Patent (Patent No. 202635468U) discloses a fish cleaning device, including a water tank for holding cleaning water. The device is characterized by: at least two pairs of supporting guide wheels installed on the inner side walls at the front and rear of the water tank, with rollers that cooperate with the supporting guide wheels, and small holes evenly distributed on the rollers; a water inlet pipe for adding water to the water tank is provided at the rear of the water tank; and a support frame connected to the water tank is provided above the end of the rollers where the fish meat enters, with a drive motor for driving the rollers to rotate on the support frame.

[0004] According to the aforementioned public document, the fish cleaning device tends to shred the fish meat when the drum rotates, and the fish meat in the middle of the drum often cannot be cleaned properly. Utility Model Content

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] In the attached diagram, all identical reference numerals refer to the same components.

[0027] Example 1, as Figure 1-5 As shown, this utility model provides a fish paste washing and filtration device, which includes the following core structure:

[0028] Frame 1: A rectangular frame welded from channel steel, on which all components are mounted.

[0029] The feeding assembly 2 includes a feeding hopper 21: a conical stainless steel hopper with a top opening size of 600×800mm and a bottom outlet width of 300mm; a gate-type baffle 22: a 304 stainless steel plate with a thickness of 10mm, slidably embedded in the bottom guide groove of the feeding hopper 21; and a switching cylinder 23: the cylinder body is bolted to the side column of the frame 1, and the piston rod is rigidly connected to the end of the baffle 22 through a flange, controlling the outlet opening degree from 0-100mm. The cylinder 23 pushes the baffle 22 to slide horizontally, achieving precise flow rate adjustment.

[0030] The spray oscillation assembly 3 includes a slide support 31: an L-shaped steel plate, vertically fixed to the frame 1 by M16 bolts; an inclined guide rail 32: two sets of linear guide rails, inclined at 15°, 1200mm in length, bolted to the inclined surface of the slide support 31; a slide fixing plate 33: a rectangular steel plate, with a bottom slider engaging with the guide rail 32, and a cleaning funnel 34 welded to the top; a cleaning funnel 34: made of stainless steel, with an upper diameter of 400mm and a bottom discharge port of φ150mm; a guide rail drive cylinder 35: the cylinder body is hinged to the base of the slide support 31, and the piston rod is hinged to the side ear plate of the slide fixing plate 33; and a conical nozzle 36: four evenly distributed water pipes, with a nozzle diameter of 1.5mm, a water pressure of 1.2MPa, and an inlet connected to an external centrifugal pump. The cylinder 35 drives the slide fixing plate 33 to reciprocate along the guide rail 32, causing the fish paste to tumble inside the funnel 34, which, in conjunction with high-pressure spraying, removes surface impurities.

[0031] The vibrating feeding assembly 4 includes a feeding channel 41: a trapezoidal stainless steel cylinder with an upper opening width of 300mm, a lower opening width of 150mm, and a height of 600mm; and a vibrating motor 42: fixed to a mounting base on the side wall of the channel 41 by bolts, with the vibration direction perpendicular to the inclined surface of the channel (i.e., horizontal). Vibration causes the fish paste to fall evenly, avoiding accumulation and blockage.

[0032] Filter press assembly 5: The elastic support base 52 is fixed to the table surface of the frame 1 by 4 sets of rubber shock absorbers (stiffness coefficient 50N / mm); Vibration platform 51: suspended above the frame 1 by shock absorbers; Filter press box 53: fixed to the platform 51 by bolts, the internal filter press chamber 54 has a size of 400×400×400mm; Detachable filter plate 57: 304 stainless steel plate, screen hole diameter 1mm, magnetically fixed to both sides of the filter press chamber 54; Discharge hole 58: 5mm wide, with a feed hopper 59 welded to the bottom.

[0033] The synchronous extrusion mechanism 55 includes: horizontal guide holes 551: 20 holes with a diameter of 50mm, located on the right side wall of the filter press box 53; extrusion rods 56: 4 φ45mm alloy steel rods, passing through the guide holes 551; connecting fixing seat 553: a rectangular frame, welded to fix the outer ends of all extrusion rods 56; a scaling linkage mechanism 554: a trapezoidal four-bar linkage, with a waist rod length of 500mm and a bottom rod length of 300mm; and an extrusion cylinder 555: the cylinder body is hinged to the side of the material conveying channel 41, and the piston rod is hinged to the midpoint of the waist rod. When the cylinder 555 retracts, the linkage mechanism 554 pushes the extrusion rods 56 to move inward synchronously, forming multi-directional extrusion.

[0034] Example 2, for fish species with high bone spines (such as carp), optimizes the filter press structure based on Example 1: the linkage mechanism 554 is upgraded: the length of the waist rod is increased to 600mm, and the middle node is reinforced with a cast steel hinge block; the output force of the extrusion cylinder 555 is increased to 1kN to ensure that the bone spine crushing rate is ≥99%;

[0035] Example 3 adds an automated control strategy based on Example 1: The switching cylinder 23 is linked with the guide rail drive cylinder 35; when the feed rate exceeds 300 kg / h, the frequency of cylinder 35 automatically increases to 3 Hz; the pressure of the extrusion cylinder 555 is dynamically adjusted: the initial extrusion pressure is 8 MPa, and it automatically increases to 15 MPa when resistance feedback is encountered. A pressure sensor is added to the water inlet pipe of the conical nozzle 36 to maintain a water pressure of 1.2 ± 0.1 MPa; the spray wastewater is filtered through the bottom collection tank and then returned to the water pump, achieving a water saving rate of 40%.

[0036] The method of using this utility model is as follows:

[0037] 1. Feeding stage: Fish paste falls from the feed hopper 21, and the opening of the gate baffle 22 is controlled by the cylinder 23 to 50mm;

[0038] 2. Cleaning stage: The fish paste falls into the cleaning funnel 34 and is rinsed for 30 seconds by 1.2MPa water pressure under the 15° tilting and shaking driven by the cylinder 35.

[0039] 3. Conveying stage: The fish paste falls along the conveying channel 41, and the vibrating motor 42 vibrates laterally at a frequency of 1000 rpm to prevent blockage.

[0040] 4. Filtration stage: The extrusion cylinder 555 pushes the connecting rod mechanism 554, so that the four extrusion rods 56 simultaneously extrude the fish paste for 12 seconds. The fish meat is squeezed out from the discharge hole 58, and the bones remain in the filter chamber 54. The water is discharged from the detachable filter plate 57.

[0041] This utility model is a fish paste washing and filtration device. Through modular design, it optimizes the entire process of washing, conveying and pressing, providing a highly reliable solution for the industrial production of fish paste products.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
