Description

Technical Field

[0001] This utility model relates to the technical field of water-soluble fertilizer production, and in particular to a hydrolysate decolorization and filtration device. Background Technology

[0002] The protein complex hydrolysis method for preparing amino acid water-soluble fertilizer is a method that converts protein raw materials into amino acid water-soluble fertilizer through enzymatic hydrolysis and acid hydrolysis. It uses complex enzymes (such as alkaline protease and neutral protease) to hydrolyze for 24-48 hours under suitable temperature (45-55℃) and pH (6.0-8.0) conditions, and the enzymatic hydrolysis products have high activity.

[0003] Existing hydrolysate decolorization and filtration devices, such as the xylose hydrolysate decolorization and filtration device disclosed in utility model patent application number 201922295184.X, mainly include a decolorization tank, a filtration unit, a filter press, and a storage tank. The filtration unit includes at least three filters connected in parallel, which cycle back and forth between three working states: ready for use, ready for filtration, and ready for cleaning. In use, the xylose hydrolysate enters the filter ready for cleaning to form a waste carbon liquid with a light transmittance of 7% to 10%. The waste carbon liquid enters the filter press to form a plate and frame liquid. The plate and frame liquid enters the filter ready for filtration to form a pre-decolorized liquid with a light transmittance of 30% to 35%. The pre-decolorized liquid enters the decolorization tank and mixes with new carbon added to the decolorization tank to form a new carbon liquid. The new carbon liquid enters the ready-to-use filter to form a decolorized liquid with a light transmittance of greater than or equal to 65%.

[0004] However, amino acid water-soluble fertilizers have a high pH after hydrolysis, and the hydrolysate needs to be neutralized during filtration. Moreover, existing filtration devices have poor filtration effects and cannot completely filter out impurities in the hydrolysate. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hydrolysate decolorization filtration device that not only performs double filtration of the hydrolysate to ensure the filtration effect, but also adjusts the pH value of the hydrolysate to facilitate its subsequent application.

[0006] This utility model discloses a hydrolysate decolorization and filtration device, comprising a feeding mechanism; it also includes a centrifugation mechanism, a detection mechanism, two sets of liquid dispensing mechanisms, and a filtration mechanism. The centrifugation mechanism is installed on the feeding mechanism and performs centrifugal filtration of the hydrolysate. The detection mechanism is installed on the feeding mechanism and performs detection of the hydrolysate. Both sets of liquid dispensing mechanisms are installed on the feeding mechanism and respectively add ammonia and decolorizing agent into the centrifugation mechanism. The filtration mechanism is installed on the feeding mechanism and performs secondary filtration of the hydrolysate. The feeding mechanism delivers the hydrolysate to the centrifugation mechanism, the detection mechanism detects the pH value of the hydrolysate, and the operator quantitatively adds ammonia and decolorizing agent into the centrifugation mechanism through the two sets of liquid dispensing mechanisms. The centrifugation mechanism stirs the hydrolysate, then performs centrifugal filtration of the hydrolysate, and finally discharges the hydrolysate after secondary filtration by the filtration mechanism.

[0007] Preferably, the feeding mechanism includes a filter cylinder, an inlet pipe, a metering valve, six sets of hydraulic cylinders, and three sets of arc-shaped baffles. The bottom end of the filter cylinder is connected to the ground, and the filter cylinder has an internal cavity. The inlet pipe is connected to the top of the filter cylinder.

Multiple sets of stirring rods are all mounted on the centrifuge cylinder. The hydrolysate and decolorizing agent are respectively delivered into the centrifuge cylinder. Three sets of arc-shaped baffles prevent the hydrolysate from overflowing. The motor is started, and the motor drives the drive shaft and the centrifuge cylinder to rotate through the reducer. The centrifuge cylinder drives the multiple sets of stirring rods to rotate and stir the hydrolysate and decolorizing agent, accelerating the decolorization of the hydrolysate. Then, six sets of hydraulic cylinders drive the three sets of arc-shaped baffles to contract and separate. The hydrolysate is thrown out under the action of centrifugal force and enters the cavity of the filter cylinder. The drive shaft drives the scraper to rotate, accelerating the hydrolysate to enter the filtration mechanism for secondary filtration.

[0009] Preferably, the testing mechanism includes a pH meter, a probe, and a display screen. The pH meter is installed on the filter cartridge, the top of the probe is connected to the bottom of the pH meter, and the probe extends into the centrifuge cartridge. The display screen is installed on the probe. The probe detects the pH value of the hydrolysate, and the test result is displayed on the display screen, which makes it convenient for staff to add an appropriate amount of ammonia water based on the test result.

[0010] Preferably, the liquid preparation mechanism includes a connecting pipe, a valve, a liquid storage tank, a sealing cap, and a handle. The bottom end of the connecting pipe is connected to the top of the filter cylinder. The valve is installed on the connecting pipe. The bottom end of the liquid storage tank is connected to the top of the connecting pipe. The sealing cap is rotatably installed on the liquid storage tank. The handle is installed on the sealing cap.

The operator opens the corresponding valve as needed to deliver the ammonia water and decolorizing agent into the cavity of the filter cylinder respectively.

[0011] Preferably, the storage tank is made of glass and has graduation lines marked on it; the graduation lines make it easy for staff to accurately control the amount of ammonia and decolorizing agent added, and avoid excessive addition which would create new impurities.

[0012] Preferably, the filtration mechanism includes a filter plate, an activated carbon adsorption box, a collection hopper, a drain pipe, and a discharge valve. The filter plate is installed at the bottom of the cavity of the filter cylinder. The top of the activated carbon adsorption box is connected to the bottom of the filter plate.
