Description

Technical Field

[0001] The utility model relates to the technical field of vermicelli production, in particular to a wastewater recycling device for vermicelli production. Background Art

[0002] Vermicelli is mainly a strip or filament non-instant food made from sweet potato starch, potato starch or bean starch as the main raw materials through processes such as pulp mixing, stirring, forming, cooling, and drying. However, in the actual production process of vermicelli, wastewater will be generated in many links. If these wastewaters are directly discharged, it will not only waste water resources but also pollute the ecological environment;

[0003] Since the wastewater generated from vermicelli production contains many recyclable elements and has a high recycling value, a recycling device for recovering protein from vermicelli production waste liquid has emerged. Existing such devices usually adopt the method of heating and stirring, arrange heat conduction pipelines in the interlayer between the inner and outer walls of the recovery barrel, introduce hot steam into the pipelines, and cooperate with the stirring device installed in the barrel to precipitate the recyclable substances in the wastewater for vermicelli production, and then filter and recycle. This method has a long filtration time, low separation efficiency, and poor separation effect. Summary of the Utility Model

[0004] Regarding the problems existing in the prior art, a wastewater recycling device for vermicelli production provided by the utility model can shorten the filtration time and improve the separation efficiency.

[0005] To achieve the above object, the technical scheme adopted by the utility model is as follows: A wastewater recycling device for vermicelli production includes a separation barrel.

The filter screen is installed on the inner wall of the water passing port. A sealing plug is plugged at the water passing port. The sealing plug is located below the filter screen;

[0008] The first valve is opened and the second valve is closed. Hot steam is introduced into the reaction chamber to push the sealing plug out from the water passing port, and the increased pressure forces the wastewater to flow towards the drainage chamber.

[0009] Preferably, the interlayer is located above the drainage chamber, and the length of the interlayer is the same as the length of the reaction chamber.

[0010] Preferably, a sealing door is installed on the side wall of the separation barrel, and the sealing door is located at the position where the drainage chamber is close to the water passing port.

During filtration and drainage, the hot steam introduced into the reaction chamber gradually increases the air pressure in the chamber, forcing the wastewater in the chamber to quickly pass through the filter screen and flow towards the drainage chamber, thereby improving the filtration speed and efficiency.

[0020] 2. The present utility model plugs a sealing plug at the water passing port, so that during the heating process of the wastewater injected into the reaction chamber, all the water in it can stay in the reaction chamber, enabling the wastewater to have strong fluidity and be fully heated under the agitation of the stirring roller, thereby improving the extraction rate of protein.

Detailed Embodiment

[0025] For the convenience of those skilled in the art to understand, the present utility model will be further described below with reference to the drawings.

[0026] As Figure 1-2 shown, a wastewater recycling device for vermicelli production includes a separation barrel 1. A filter screen 14 is installed inside the separation barrel 1. The filter screen 14 divides the interior of the separation barrel 1 into a reaction chamber 15 and a drainage chamber 9. The reaction chamber 15 is located above the drainage chamber 9. The upper end of the separation barrel 1 is connected with a liquid injection pipe 3 communicating with the reaction chamber 15, and the lower end of the separation barrel 1 is provided with a liquid discharge pipe 10 communicating with the drainage chamber 9;

[0027] A water passing port 12 is provided between the drainage chamber 9 and the reaction chamber 15 of the present utility model. The upper end of the water passing port 12 is provided with a material guiding slope 8 inclined downward along the axis direction of the separation barrel 1 to drain the wastewater in the reaction chamber 15, so that both the protein and the wastewater can smoothly flow to the water passing port 12.

[0028] Specifically, the filter screen 14 is installed on the inner wall of the water passing port 12. A plug 13 is plugged at the water passing port 12. The plug 13 is in interference fit with the inner wall of the water passing port 12. Before the protein in the wastewater is fully denatured and forms a precipitate. The plug 13 plugged at the water passing port 12 can block the passage between the drainage chamber 9 and the reaction chamber 15, so that all the wastewater remains in the reaction chamber 15.

[0029] An air delivery pipe 18 is installed on the separation barrel 1 of the utility model. A sandwich layer 6 is provided on the side wall of the separation barrel 1. The sandwich layer 6 is located above the drainage cavity 9. The length of the sandwich layer 6 is the same as the length of the reaction cavity 15. A heat conduction pipeline 7 is arranged in the sandwich layer 6. One end of the air delivery pipe 18 is connected to a gas supply device for delivering hot steam. One end of the heat conduction pipeline 7 is connected to the air delivery pipe 18. The hot steam delivered by the gas supply device into the heat conduction pipeline 7 heats the reaction cavity 15, so that the wastewater in the reaction cavity 15 is heated, and the proteins inside are deformed, which is convenient for recovery.

[0030] Specifically, the heat conduction pipeline 7 is closely attached to the side of the sandwich layer 6 close to the reaction cavity 15. The sandwich layer 6 is filled with a heat insulation material 5, which can improve the heat preservation of the separation barrel 1, avoid waste of heat, achieve a better heating effect, and at the same time, the heat insulation material 5 can also play a role in fixing the heat conduction pipeline 7.

[0031] The other end of the air delivery pipe 18 of the utility model passes through the sandwich layer 6 and extends into the reaction cavity 15. A stirring device is installed in the reaction cavity 15. The stirring device includes a motor 2 and a stirring roller 16. The motor 2 is installed at the upper end of the separation barrel 1. The upper end of the stirring roller 16 passes through the separation barrel 1 and is connected to the motor 2. The stirring of the stirring roller 16 enables the wastewater to fully contact the inner wall of the reaction cavity 15. The heat in the heat conduction pipeline 7 in the sandwich layer 6 can be transferred to the reaction cavity 15, so that the proteins are fully heated and denatured;

[0032] A first valve 17 is installed at one end of the air delivery pipe 18 close to the reaction cavity 15. A second valve 20 is installed on the heat conduction pipeline 7. A check valve 4 is installed on the liquid injection pipe 3. A pressure pump 19 is installed between the air delivery pipe 18 and the gas supply device;

[0033] Specifically, the wastewater injected from the liquid injection pipe 3 first enters the reaction cavity 15. The proteins in the wastewater are converted into flocculent precipitates in the reaction cavity 15. Then, the first valve 17 is opened, the second valve 20 is closed, and the pressure pump 19 is turned on. The pressurized hot steam is introduced into the reaction cavity 15. The sealing plug 13 is located below the filter screen 14. The increased air pressure pushes the sealing plug 13 open, and the reaction cavity 15 is communicated with the drainage cavity 9, and the wastewater can flow into the drainage cavity 9;

[0034] Specifically, the increased pressure in the reaction cavity 15 can also accelerate the flow rate of the wastewater towards the drainage cavity 9, thereby accelerating the speed of the wastewater passing through the filter screen 14, greatly reducing the filtration time, and improving the filtration efficiency. In addition, directly introducing the hot steam into the reaction cavity 15 can also directly heat the internal wastewater, further avoiding the possibility that some proteins fail to denature and form precipitates due to uneven heating of the wastewater, and improving the protein extraction rate.

[0035] A sealing door 11 is installed on the side wall of the separation barrel 1 of the utility model. The sealing door 11 is located near the water inlet 12 of the drainage cavity 9. The filter screen 14 is detachably installed on the water inlet 12. The diameter of the filter screen 14 is smaller than the width of the sealing door 11. After the filtration is completed, when taking out the protein precipitate, only need to open the sealing door 11, disassemble the filter screen 14 and take it out. After cleaning the filter screen 14, reset it and plug the plug 13 back into the water inlet 12 for the next separation.

[0036] It should be understood that the use of these embodiments is only for illustrating the present utility model and is not intended to limit the protection scope of the present utility model. In addition, it should also be understood that after reading the technical content of the present utility model, those skilled in the art can make various changes, modifications and / or variations to the present utility model, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
