Description

Technical Field

[0001] The utility model relates to the technical field of cellulose glucose production equipment, in particular to a pneumatic stirring and conveying device for cellulase. Background Art

[0002] Plant fiber can be used to obtain non-food bio-based glucose through enzymatic hydrolysis, which can effectively solve the problems of "competing with people for food and competing with livestock for feed" and carbon emissions, and has a positive effect on environmental protection and comprehensive utilization of resources.

[0003] Cellulose glucose is an extract of plant fiber. Cellulase needs to be added in its industrial production process. As a biologically active protein, the shear force will destroy the delicate spatial structure of the enzyme protein molecules to a certain extent. It is generally believed that the enzyme activity decreases with the increase of shear intensity and shear time. Due to the high price of cellulase, the partial inactivation of the enzyme will not only increase the production cost, but also seriously affect the quality of subsequent products.

[0004] In the existing production process, a stirring tank is often used to dissolve and dilute the enzyme and a centrifugal pump is used to pump it into the subsequent saccharification tank. Shear force will be generated during the stirring and conveying process of the centrifugal pump, which will undoubtedly have a certain impact on the enzyme activity, thereby increasing production costs and affecting product quality. Therefore, a stirring and conveying device that can effectively ensure the enzyme activity during the dissolution, dilution and conveying process of cellulase is an existing problem that needs to be solved. Utility Model Content

[0005] The utility model aims to provide a pneumatic stirring and conveying device for cellulase in view of the above-mentioned deficiencies of the prior art, so as to achieve the purpose of ensuring the enzyme activity during the process of dissolving, diluting and conveying the cellulase.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pneumatic stirring and conveying device for cellulose enzyme, comprising a tank body, an air inlet is arranged at the bottom of the tank body, the air inlet is connected to the air inlet pipe, and the air inlet is arranged tangentially along the tank body; a feed inlet, a water inlet and an air outlet are respectively arranged at the top of the tank body, the feed inlet is connected to the feeder, the water inlet is connected to the water inlet pipe, and the air outlet is connected to the air outlet pipe; a discharge port is arranged at the bottom of the tank body, and the discharge port is connected to the conveying pipe.

[0007] Furthermore, the feeder includes a feed hopper, the lower part of the feed hopper is connected to a feed pipe, and the feed pipe is connected to a feed port.

[0008] Furthermore, the air intake pipe is provided with an air intake control valve, the feed pipe is provided with a feed control valve, the water inlet pipe is provided with a water inlet control valve, the air outlet pipe is provided with an air outlet control valve, and the delivery pipe is provided with a delivery control valve.

[0009] Furthermore, the discharge port is also connected to a drain pipe, and a drain control valve is provided on the drain pipe.

[0010] Furthermore, a spoiler is arranged inside the tank in the direction of liquid flow.

[0011] Furthermore, three spoilers are provided and are evenly spaced, and the spoilers on both sides of the air inlet are symmetrically arranged relative to the air inlet.

[0012] Furthermore, a gap is provided between the spoiler and the inner wall of the tank body.

[0013] Beneficial effects of the utility model:

[0014] 1. The structure is simple and stable. Through pneumatic stirring and pneumatic conveying, it can effectively avoid the damage of traditional mechanical shear force to the activity of cellulase, thereby ensuring the activity of cellulase, which plays a positive role in reducing production costs and ensuring product quality;

[0015] 2. Through the arrangement of the spoiler inside the tank, the solution in the tank can be quickly mixed and evenly under pneumatic stirring, which on the one hand reduces the time of dissolution and mixing and improves the mixing efficiency; on the other hand, it also avoids the long-term inactivation of cellulase and plays a role in promoting the activity of cellulase.

[0023] like Figure 1-3 As shown, in the stirring and conveying equipment of this embodiment, a tank body 1 is provided, a feed port 11 is provided above the tank body 1, and the feed port 11 is connected to a feeder 2; wherein, the feeder 2 includes a feed hopper 21, a feed pipe 22 is provided below the feed hopper 21, the feed pipe 22 is connected to the feed port 11, and a feed control valve 23 is installed on the feed pipe 22.

[0024] A water inlet 12 is arranged above the tank body 1, the water inlet 12 is connected to the water inlet pipe 3, and a water inlet control valve 31 is installed on the water inlet pipe 3; an air inlet 13 is arranged below the tank body 1, the air inlet 13 is connected to the air inlet pipe 4, and an air inlet control valve 41 is installed on the air inlet pipe 4; correspondingly, an air outlet 14 is arranged above the tank body 1, the air outlet 14 is connected to the air outlet pipe 5, and an air outlet control valve 51 is installed on the air outlet pipe 5.

[0025] A discharge port 15 is provided at the bottom of the tank body 1, and the discharge port 15 is respectively connected to a conveying pipe 6 and an emptying pipe 7, a conveying control valve 61 is installed on the conveying pipe 6, and an emptying control valve 71 is installed on the emptying pipe 7; the conveying pipe 6 conveys the dissolved, diluted and mixed cellulase solution to the cellulose saccharification tank at the rear end.

[0026] In this embodiment, the feed control valve 23 is a gate valve; the air intake control valve 41 is a check valve; the water inlet control valve 31, the air outlet control valve 51, the delivery control valve 61 and the exhaust control valve 71 are ball valves.

[0027] The air inlet 13 is arranged tangentially at the bottom of the tank body 1, and a spoiler 16 is arranged from top to bottom in the tank body 1. Three spoilers 16 are provided and are evenly arranged at intervals. The wide sides of the spoilers 16 are arranged toward the direction of water flow. The spoilers 16 disturb the water flow, and a gap is provided between the spoilers 16 and the inner wall of the tank body 1.

[0028] The principle of this utility model is:

[0029] During the use of the utility model, cellulase is added into the tank body 1 through the feeder 2, and the tangential direction of the bottom of the tank body 1 is connected to the air inlet pipe 4, wherein the air inlet pipe 4 is a compressed air pipe; after the cellulase is added into the tank body 1, an appropriate amount of water is added through the water inlet pipe 3; at this time, the air inlet control valve 41 on the air inlet pipe 4 is opened, and the compressed air pushes the cellulase and water to mix and dissolve in the tangential direction, and the air entering the tank body 1 is discharged through the air outlet pipe 5 above the tank body 1.

[0030] During the mixing and dissolving process, under the action of the spoiler 16 in the tank body 1, the cellulase and water in the tank body 1 are quickly mixed and uniform. At this time, only the air intake control valve 41 and the delivery control valve 61 are kept open, and other valves are closed. As the pressure in the tank body 1 increases, the cellulase solution in the tank body 1 is pressed into the saccharification tank at the rear end through the delivery pipe 6, thereby realizing the dissolution and addition process of the entire cellulase. In this process, the damage of the cellulase to the shear force is effectively avoided, the activity of the cellulase is guaranteed, and it has a positive effect on reducing production costs and ensuring product quality.
