Description

Technical Field

[0001] The utility model relates to the technical field of artificial casing manufacturing, in particular to a collagen casing acid-base adjustment device. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] In the production process of collagen artificial casings, when the collagen casings are dried, the pH value of the collagen casings needs to be adjusted to change the state of the collagen fibers in the collagen casings, improve the structural stability and mechanical properties of the collagen casings, and prevent the casings from rupturing during enema. The prior art generally uses spraying sodium carbonate or sodium bicarbonate solution to adjust the pH of the collagen casings. However, this method causes a large amount of salt, namely ash, to be mixed into the collagen casings. Since the ash affects the oil and water absorption properties of the protein, the function of the collagen casings is reduced. In order to improve the functionality and quality of the collagen casings, the ash of the casings needs to be removed. The steps are cumbersome and the ash is difficult to completely remove. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of an embodiment of the utility model is to provide a device for adjusting the acidity and base of collagen casings, which adjusts the pH value of the collagen casings by neutralizing the acidity of the casings with ammonia gas, thereby preventing ash from being mixed in during the neutralization process of the casings.

[0005] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0006] A device for adjusting the acidity and alkaliity of collagen casings, comprising:

[0007] A casing, wherein a casing inlet area, a working area and a casing outlet area are sequentially arranged in the casing along the moving direction of the casing, and the casing inlet area and the casing outlet area are both arranged higher than the working area;

[0011] The utility model introduces ammonia into the working area and directly uses ammonia to adjust the pH value of the collagen casing, thereby achieving the casing neutralization process without mixing in ash, further improving the structural stability and mechanical properties of the casing, improving the flexibility of the casing, and preventing the casing from rupturing during enema; at the same time, the setting of the ammonia sensor can detect the concentration of ammonia in the working area so as to control the concentration range of ammonia.

[0012] In some embodiments, the housing includes a lower housing and a shield, the shield is detachable, and the shield and the lower housing are sealingly connected.

[0013] In some embodiments, the shield and the lower shell are connected by bolts or by snap-fit ​​connection, and the shield and the lower shell are sealed by a sealing strip.

[0014] In some embodiments, a spray device is further included, which is installed at the top of the working area. When the ammonia concentration is too high, the spray device is turned on to spray water.

[0015] In some embodiments, a V-shaped water collection trough is provided at the bottom of the lower shell for collecting waste water.

[0016] In some embodiments, the conveying rollers in the casing inlet area, the working area, and the casing outlet area are evenly arranged.

[0017] In some embodiments, the conveying rollers are all arranged at the bottom of the casing inlet area, the working area and the casing outlet area.

[0018] In some embodiments, a host and an actuator are also included. The host is used to receive data uploaded by the ammonia sensor, compare the data with a pre-set ammonia concentration parameter, and transmit an action signal to the actuator.

[0021] One or more technical solutions provided in the embodiments of the present utility model have at least the following technical effects or advantages:

[0022] 1. The utility model directly uses ammonia to adjust the pH value of the collagen casing without mixing in ash, thereby realizing the neutralization process of the collagen casing, further improving the structural stability and mechanical properties of the casing, improving the flexibility of the collagen casing, preventing the casing from rupturing during enema, and improving the performance of the collagen casing; at the same time, ammonia is used instead of the existing spraying of sodium carbonate or sodium bicarbonate solution to adjust the pH value of the collagen casing, thereby improving the drying efficiency of the subsequent drying stage and reducing the energy consumption in the drying stage.

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] As introduced in the background technology, in the prior art, the pH of collagen casings is generally adjusted by spraying sodium carbonate or sodium bicarbonate solution, so that a large amount of salt is mixed into the collagen casings. It is also necessary to reduce the ash content of the casings. The steps are cumbersome and the ash is difficult to completely remove, which reduces the function and quality of the collagen casings. In order to solve the above technical problems, the utility model proposes a acid-base adjustment device for collagen casings.

[0030] like Figure 1As shown, an embodiment of the utility model records a device for adjusting the acidity and alkali of collagen casings, comprising: a shell, which is used to form a casing inlet area 1, a working area 2 and a casing outlet area 3, and the shell is sequentially composed of the casing inlet area 1, the working area 2 and the casing outlet area 3 along the moving direction of the casing, the casing inlet area 1 and the casing outlet area 3 are both arranged higher than the working area 2, the casing inlet area 1 and the casing outlet area 3 are respectively provided with a casing inlet and a casing outlet, a conveying roller 8 is arranged in the casing inlet area 1, the working area 2 and the casing outlet area 3, and the conveying roller 8 is driven by a power device, an ammonia injection port 9 and an ammonia sensor 10 are arranged in the working area 2, and ammonia is introduced into the working area 2 through the ammonia injection port 9; an ammonia sensor 10 is arranged to detect the ammonia concentration.

[0031] Optionally, the main structure of the shell is stainless steel, including a lower shell 5 and a box cover 4. The box cover 4 and the lower shell 5 are separately arranged, and the box cover 4 is detachable, so that personnel can open the box cover 4 for maintenance or operation. The shell and the box cover 4 are sealed and connected, preferably by silicone strips, rubber strips and other rubber strips. The shell and the box cover 4 are connected by bolts, and can also be snap-fitted to achieve stable fixation. The length of the shell is set according to actual needs, and in some embodiments, it is preferably 12 meters.

[0032] Optionally, conveying rollers 8 are arranged in the casing inlet area 1, the working area 2 and the casing outlet area 3, the casing is placed above the conveying rollers 8, at least part of the conveying rollers 8 are connected to the power device, driven to rotate by the power device, the conveying rollers 8 rotate in the same direction, and push the casing from the inlet direction to the outlet direction, preferably, all the conveying rollers 8 are connected to a small stepping motor to drive the conveying rollers 8 to rotate in the same direction, and the conveying rollers 8 in the working area 2 are evenly arranged. When the casing passes through the adjustment device, it is conveyed by the conveying rollers 8 and passes through the casing inlet area 1, the working area 2 and the casing outlet area 3 in sequence.

[0033] Optionally, a plurality of ammonia injection ports 9 are provided in the working area 2, and the ammonia injection ports 9 are evenly arranged on the bottom surface of the working area 2, and the ammonia injection ports 9 are arranged horizontally. Ammonia is evenly injected horizontally from the vicinity of the conveying roller 8 through the ammonia injection ports 9 to ensure that the ammonia concentration at different positions in the working area 2 is equivalent.

[0034] Optionally, a plurality of ammonia sensors 10 are evenly arranged at the bottom of the working area 2 to detect the concentration of ammonia in the working area 2 and transmit the detection data to the host for processing and analysis.

[0035] Optionally, the spray device 7 is installed at the top of the working area 2 and is connected to a water pipe. When the ammonia concentration in the working area 2 is too high, the spray device 7 is turned on to release water droplets to absorb the ammonia in the working area 2 to reduce the concentration of the gas.

[0036] Optionally, a flow valve is connected to the ammonia injection port 9 and the ammonia source respectively, and the flow valve switches or adjusts the flow of ammonia to achieve the adjustment of the ammonia concentration in the working area 2.

[0037] Optionally, it also includes a host, which is connected to the ammonia sensor 10 and the actuator. The host is an existing structure. The actuator includes a spray device 7 and an ammonia flow valve.

[0038] Optionally, a V-shaped water collecting trough 6 is provided at the bottom of the lower shell 5 for collecting waste water generated when the casing passes through the working area 2 or water sprayed by the spraying device 7 .

[0039] Since the air contains water vapor, ammonia absorbs moisture in the air to produce NH3·H2O. According to the phenomenon that NH3·H2O sinks in the air, the inlet and outlet of the casing are higher than the working area 2, thereby reducing the leakage of ammonia from the inlet and outlet of the casing; ammonia is introduced into the working area 2 through the ammonia injection port 9, and then the conveying roller 8 is rotated in the same direction by the motor, and the conveying roller 8 drives the casing to move from the inlet direction to the outlet direction. The sensor detects the concentration of ammonia in the working area 2 and uploads the data signal to the host. The host processes and compares the data and sends an action signal to adjust the speed of ammonia injection into the working area 2 through the flow valve. When the ammonia concentration is higher than the limit value, the spray device 7 is started, the ammonia flow valve is closed, ammonia is absorbed, and the ammonia concentration in the working area 2 is reduced. The water collection tank 6 below the shell collects and discharges waste water.

[0040] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
