Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an oil slurry filter. Background Art

[0002] At present, the most common method of producing edible oil is pressing. The specific production process is as follows: raw materials (peanuts, rapeseed, soybeans, sunflower seeds, etc.) - screening and removing impurities - heating and stir-frying - screw oil press pressing - crude oil filtration - water washing - alkali refining - white clay bleaching - filtration - deodorization - filtration - filling - finished oil.

[0003] For the filtering process, the old plate and frame filter was used in the past. Because it is an open-air filtering, the product is easily contaminated again, the color is not pure, and the product quality is affected, which greatly reduces the appearance in the later stage. Nowadays, most canister filters are used for sealing, but the oil slurry has a high viscosity, the filtering time is long, and the efficiency is low. In order to improve the filtering efficiency of the oil slurry and speed up the filtering process, a patent document with announcement number CN202410292U discloses an edible oil filtering device, including an oil receiving box, a filter box, and a pressurizing box. The filter box is buckled at the upper end of the oil receiving box. After the oil slurry is injected into the filter box, the pressurizing box is inserted into the filter box, and then the pressurizing box is manually pressed, and the pressurizing box moves down, so that the pressure in the filter box increases, which promotes the oil slurry to filter the filter paper, thereby shortening the filtering time.

[0004] However, the problems with the above patents are:

[0005] 1. Even if the filtration efficiency is improved, manual pressing will still increase the operation time and labor burden;

[0006] 2. A mesh through hole is provided at the bottom of the filter box to form a filter plate, and the filter plate is covered with filter paper. The filter paper improves the filtering accuracy. However, it should be noted that the filter paper is a consumable material and needs to be replaced from time to time, and the filter plate also needs to be cleaned. The setting of this patent makes the filter plate embedded in the oil collection box, which is inconvenient to replace the filter paper.

[0007] To this end, the utility model provides an oil slurry filter to solve the problems of slow manual operation efficiency and inconvenient filter paper replacement. Utility Model Content

[0008] The utility model aims to solve the problems existing in the prior art and proposes an oil slurry filter.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0016] Preferably, the side wall of the oil receiving hopper is provided with a plurality of hanging ears, and the bottom end of each hanging ear is connected to a hydraulic rod.

[0017] Compared with the prior art, the utility model provides an oil slurry filter, which has the following beneficial effects:

[0018] 1. The motor drives the crank to rotate continuously through the rotating shaft, thereby driving the piston to move back and forth vertically in the pressurized chamber through the rocker. When the piston rises to the top of the stroke, the oil slurry seeps from the gap between the sink and the piston to the space below the pressurized chamber. When the piston descends, the piston squeezes the oil slurry, thereby increasing the pressure in the pressurized chamber and promoting the oil slurry to pass through the filter box quickly. The filtered oil slurry is discharged from the oil outlet. In this way, through the continuous operation of the motor, the piston reciprocates to squeeze the oil slurry for rapid filtration, which not only improves the filtration efficiency, but also does not require manual operation, is simpler and more labor-saving; and the oil slurry can be continuously supplied through the oil filling pipe for uninterrupted operation, which greatly improves the continuity of the oil slurry filtration operation.

[0019] 2. The filter box includes a supporting ring arranged on the inner wall of the upper end of the oil receiving hopper. The supporting ring is overlapped with a filter screen, filter paper and a pressure ring in sequence from bottom to top, so that the filter screen and filter paper can be removed and replaced. A plurality of hanging ears are arranged on the side wall of the oil receiving hopper. The bottom end of each hanging ear is connected to a hydraulic rod. The extended end of the hydraulic rod is extended, and the oil receiving hopper is abutted against the bottom end of the oil tank for receiving oil; the extended end of the hydraulic rod is retracted, the oil receiving hopper is separated from the oil tank, and the upper end of the oil receiving hopper leaks out. The pressure ring can be removed to replace the filter paper and clean the filter screen, which is convenient and quick.
