Abstract
Description
Technical Field
[0001] This utility model relates to the field of corn steep liquor by-product processing technology, specifically a solid-liquid separation device for corn steep liquor production by-products. Background Technology
[0002] Corn syrup solid-liquid separation devices are divided into centrifugal separation equipment, screw presses, plate and frame filter presses, etc. The equipment obtains liquid and filter residue, which can be further processed as needed. Among them, the filter press uses pressure to trap the solids in the syrup on the surface of the filter cloth to form a filter cake, thereby achieving solid-liquid separation. It is used for fine filtration of corn germ crude oil and deep deimpurification of corn syrup.
[0003] Existing filter presses mostly overcome the problem of increased filtration resistance caused by thickened filter cake by pressurizing, allowing liquid to penetrate the solid layer faster and improving filtration speed. This places high demands on the system's sealing performance. The hydraulic system applies high pressure to the plates and frames to prevent material leakage and ensure a tight and stable filtration process, which poses a significant challenge to the durability of the entire filtration system.
[0004] Existing corn slurry filtration systems typically utilize filter presses, which are not very convenient to use. Cleaning the filter residue often requires applying water to the inner walls of the device, which is also inconvenient. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This is a solid-liquid separation device for corn syrup production by-products. It uses a pressure plate instead of the pressurization device of a traditional filter press.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] Please refer to Figures 1-5.
[0022] A solid-liquid separation device for corn syrup production by-products includes a main body consisting of an outer separation tank 1 and an inner separation tank 11. The outer separation tank 1 is sleeved on the outside of the inner separation tank 11, and the gap between the outer separation tank 1 and the inner separation tank 11 is an inner cavity 10. A feed pipe 2 is installed through the left side of the outer separation tank 1, passing through the inner cavity 10 and extending into the interior of the inner separation tank 11. A discharge pipe 3 is installed through the left side of the outer separation tank 1. A hydraulic device 4 is fixedly installed on the top of the outer separation tank 1. The inner threaded connection is a threaded rod 5. The inner side of the outer separation tank 1 is slidably connected to a bottom plate 7. The top of the bottom plate 7 is provided with an embedded plate 8. The bottom of the bottom plate 7 is provided with a sliding plate 6. The fixed plate 9 is provided inside the outer separation tank 1. The inner side of the outer separation tank 1 is fixedly installed with a hydraulic rod 13. The output end of the hydraulic rod 13 is fixedly installed with a pressure plate 12. The outer wall of the pressure plate 12 is fixedly fitted with a scraper 14. The pressure plate 12 is fixedly installed around its perimeter with a soft filter plate 15. The inner separation tank 11 is provided with a filter screen 18 around its perimeter.
[0023] The scraper 14 is positioned above the flexible filter plate 15, and the flexible filter plate 15 is made of rubber.
[0024] The scraper 14 is slidably connected to the inner wall of the inner separation tank 11, and a sealing gasket is fitted on the inner side of the scraper 14.
[0025] The inner separation tank 11 is through-shaped, and the bottom of the inner separation tank 11 is provided with a fitting groove, which is movably connected to the embedded plate 8.
[0026] A handle 16 is provided on the outside of the inner separation tank 11, and a sliding rail 17 is provided between the inner separation tank 11 and the outer separation tank 1.
[0027] This is a solid-liquid separation device for corn syrup production by-products. By using a pressure plate 12 instead of the pressure device of a traditional filter press, the pressure plate 12 squeezes downwards, causing the corn syrup in the inner pressure tank to pass through the filter screen 18 more quickly, thus improving the filtration efficiency of the corn syrup. This also means that the entire device does not require excessive sealing performance. Through the pressure applied by the pressure plate 12 in the inner separation tank 11 and the action of the scraper 14, the residue in the tank can be better pressed to the bottom sliding plate 6. Adjusting the spiral extrusion device to move downwards allows the bottom sliding plate 6 to be pushed out through the slide rail 17 by applying force through the handle 16, thus cleaning all the filter residue.
[0028] Working principle: During operation, corn slurry is pumped into the inner separator tank 11 through the feed pipe 2. The bottom sliding plate 6 is tightly fitted into the bottom groove of the inner separator tank 11 to ensure that the corn slurry does not leak out. The inner separator tank 11 uses four-sided filter screens 18 for filtration to achieve slurry-residue separation. During the filtration process, the hydraulic device 4 controls the hydraulic rod 13 to move downward, causing the pressure plate 12 to squeeze the corn slurry, increasing the pressure and accelerating the filtration speed. At the same time, the soft filter plate 15 on the pressure plate 12 will scrape off the residue on the inner wall. Its scraper 14 not only bears the filtration capacity but also ensures that the corn slurry does not overflow from the pressure plate 12 due to squeezing. As the corn slurry gradually passes through the filter screen 18 and enters the inner cavity 10, the filtrate will flow out through the discharge pipe 3, and the corn slurry water level in the inner separator tank 11 will drop. The pressure plate 12 will also gradually pass through the filter screen 18, separating and squeezing the residue adsorbed on it to the bottom. After the filtrate flows out, the threaded rod 5 of the bottom plate 7 is adjusted down, allowing the sliding bottom plate 7 to slide out. At this time, the upper... If slurry residue is present, it can be removed and then re-embedded at the bottom of the inner separation tank 11. There is an embedding plate 8 and a corresponding embedding groove between the two to ensure sealing performance and prevent leakage under pressure. Compared with related technologies, the solid-liquid separation device for corn syrup production by-products provided by this utility model has the following beneficial effects: This solid-liquid separation device for corn syrup production by-products uses a pressure plate 12 instead of the pressure device of a traditional filter press. When the device is working, the pressure plate 12 squeezes downward, which accelerates the corn syrup in the inner pressure tank through the filter screen 18, improving the filtration efficiency of the corn syrup. It also makes the entire device less need for excessive sealing performance. Through the pressure of the pressure plate 12 in the inner separation tank 11 and the action of the scraper 14, the residue in the tank can be better pressed to the bottom sliding plate 6. Adjusting the spiral extrusion device to move downward allows the bottom sliding plate 6 to slide out through the slide rail 17 by applying force through the handle 16, thus cleaning all the filter residue.
