[0002] Lecithin has high nutritional and medical value, possessing a variety of physiological functions, including anti-aging and enhancing brain activity. It also possesses excellent emulsifying and antioxidant properties. Therefore, lecithin is widely used in the food, pharmaceutical, and cosmetic industries.

[0003] Egg yolk lecithin is extracted from egg yolks. Existing extraction methods involve an aluminum oxide reaction and an ethanol reaction, requiring feeding through a hopper. Currently, the hopper is open at the top, often causing dust and impurities to overflow. However, due to space limitations and explosion-proof requirements, conventional recovery and processing equipment is not feasible, necessitating the use of specialized recovery equipment. Utility Model Content

[0004] The utility model aims to provide an exhaust assembly device, which can effectively collect dust and impurities overflowing from the open openings of various hopper reactions without affecting the reactions in each hopper.

[0005] The basic solution provided by the utility model is: a combined exhaust device for exhausting gaseous impurities and non-gaseous impurities generated during the aluminum oxide reaction and ethanol reaction in the reaction space;

[0006] The invention comprises an exhaust device arranged outside the reaction space, an exhaust main pipeline arranged in the reaction space, and a plurality of exhaust cylinders connected to the exhaust main pipeline; the plurality of exhaust cylinders include a first exhaust cylinder, a second exhaust cylinder, a third exhaust cylinder, and a fourth exhaust cylinder, wherein the first exhaust cylinder and the second exhaust cylinder are respectively directly above the first hopper and the second hopper for the aluminum oxide reaction, and the third exhaust cylinder and the fourth exhaust cylinder are respectively directly above the third hopper and the fourth hopper for the ethanol reaction;

[0013] Figure 2 This is a structural schematic diagram of an air extraction assembly provided in Example 2 of the present utility model. DETAILED DESCRIPTION

[0014] The following is a further detailed description through specific implementation methods:

[0015] The marks in the drawings of the specification include: the main exhaust pipe 10, the first exhaust cylinder 21, the second exhaust cylinder 22, the third exhaust cylinder 23, the fourth exhaust cylinder 24, the increased part 25, the first hopper 31, the second hopper 32, the third hopper 33, the fourth hopper 34, the impurity discharge pipe 40, the filter 41, the one-way valve 50, the exhaust equipment 60, and the collection device 70.

[0016] Example 1

[0017] Basically as attached Figure 1Shown: A combined exhaust device is used to exhaust gaseous impurities and non-gaseous impurities generated during the aluminum oxide reaction and ethanol reaction in the reaction space.

[0018] It includes an exhaust device 60 arranged outside the reaction space, an exhaust main pipe 10 arranged in the reaction space, and several exhaust cylinders connected to the exhaust main pipe 10; the several exhaust cylinders include a first exhaust cylinder 21, a second exhaust cylinder 22, a third exhaust cylinder 23 and a fourth exhaust cylinder 24, wherein the first exhaust cylinder 21 and the second exhaust cylinder 22 are respectively directly above the first hopper 31 and the second hopper 32 used for aluminum oxide reaction, and the third exhaust cylinder 23 and the fourth exhaust cylinder 24 are respectively directly above the third hopper 33 and the fourth hopper 34 used for ethanol reaction.

[0019] Specifically, the structure of the vacuum cylinder is a trumpet structure with a large port and a small port, and is connected to the main vacuum pipe 10 through the small port. The large port is adapted to the open end of the hopper, and the cross-sectional area of the large port is not less than the cross-sectional area of the open end of the hopper, and at least the two cross-sectional areas are the same, ensuring a high recovery rate. Each of the vacuum cylinders is sealed with the corresponding hopper, and the sealing method further ensures a 100% recovery rate. During recovery, the trumpet structure can make the material overflowing from the hopper open move from the large port to the small port under the action of suction, which plays a role of gathering and is conducive to the recovery flow of the material.

[0020] An impurity discharge pipe 40 is provided through the main exhaust pipe 10 between the second exhaust cylinder 22 and the third exhaust cylinder 23, and the end of the main exhaust pipe 10 close to the impurity discharge pipe 40 is lower than the end of the main exhaust pipe 10 away from the impurity discharge pipe 40, so as to form the main exhaust pipe 10 with an inclined angle. A filter 41 is provided on the impurity discharge pipe 40, and the filter 41 is located at the upper end of the portion where the main exhaust pipe 10 and the impurity discharge pipe 40 pass through. The impurity discharge pipe 40 above the filter 41 is used to discharge gaseous impurities, and the impurity discharge pipe 40 below the filter 41 is used to discharge non-gaseous impurities. The end of the impurity discharge pipe 40 for discharging gaseous impurities is connected to the exhaust equipment 60.

[0021] Specifically, the diameter, diameter difference, and length of the impurity discharge pipe 40, the main exhaust pipe 10, and the small port of the exhaust cylinder, as well as the exhaust parameters and exhaust method of the exhaust equipment 60, are reasonably set according to the existing plant space and the amount of impurities generated per unit time. Due to the change in the diameter difference or the change in the exhaust pressure on the exhaust path, the effective separation of gas and non-gaseous impurities can be achieved. The exhaust principle and system are implemented in accordance with the existing technology and will not be elaborated here. The inclination angle is 10-15 degrees, which is reasonable and is conducive to the efficient discharge of slightly heavier particulate impurities under the action of gravity. The pipeline is made of explosion-proof and fire-proof materials to ensure safe and efficient impurity extraction.

[0022] Specifically, on the main exhaust pipe 10, the distance between the impurity exhaust pipe 40 and the second exhaust cylinder 22 is greater than the distance between the impurity exhaust pipe 40 and the third exhaust cylinder 23. The alumina reaction process requires higher purity of substances than the ethanol reaction process. Therefore, setting such a distance can reduce the possibility of impurities discharged from the ethanol reaction process entering the alumina reaction process.

[0023] Specifically, the specific configuration of the filter 41, such as the hole size and arrangement of the filter 41, can be adaptively designed according to the characteristics of the actual non-gaseous impurities to achieve effective separation of gaseous and non-gaseous impurities.

[0024] One end of the impurity discharge pipe 40 for discharging gaseous impurities is also connected to an environmental protection treatment device, and the other end of the impurity discharge pipe 40 for discharging gaseous impurities is connected to a collection device 70, so as to achieve efficient treatment by classification and path. At the same time, the environmental protection treatment equipment and the collection device 70 are both located outside the reaction space to ensure the safety within the reaction space.

[0025] A one-way valve 50 is provided between each of the vacuum cylinders and the main vacuum pipeline 10 .

[0026] Specifically, the one-way valve 50 is installed on the vacuum cylinder and at one end of the vacuum cylinder close to the main vacuum pipe 10. The setting of the one-way valve 50 allows the dust and impurities overflowing from the opening to be recovered in a one-way path, neither flowing back into the hopper nor flowing into other hoppers, so as not to affect the reactions in each hopper.

[0027] In actual use, the exhaust pipe and exhaust cylinder of this scheme are installed in the reaction space, while the exhaust equipment for exhaust, including the environmental protection treatment equipment and collection equipment, are all arranged outside the reaction space. First, the reaction space is limited, and second, the operation of mechanical equipment in the reaction space is minimized to meet the explosion-proof safety requirements; under the action of the exhaust equipment 60, the material overflowing from the opening of each hopper is extracted, from the hopper opening through the exhaust cylinder, to the exhaust main pipe 10, and discharged out of the reaction space from the impurity discharge pipe 40. Among them, through the inclined exhaust main pipe 10 and the change of the suction force per unit area at the filter 41, the slightly heavier particulate impurities fall to the collection device 70 by gravity, and the light gaseous impurities are discharged upward and can be discharged into the back-end environmental protection treatment equipment; the collection device 70 can be a material separation equipment or system, especially for separating and recovering alumina powder and ethanol, recycling, energy saving and emission reduction, and reducing costs.

[0028] The present embodiment provides a vacuum combination device, which has a targeted structural design based on the characteristics that the two reaction processes need not affect each other, the difference in impurity types, and the limitations and explosion-proof requirements of the space where the reaction processes are located. It can effectively collect impurities overflowing from the open mouth of each hopper reaction, and can also realize the classified and path-based recovery of gaseous impurities and non-gaseous impurities (such as particulate impurities with a certain weight), meeting the requirements of energy conservation and emission reduction. At the same time, the setting of the one-way valve does not affect the reactions in each other's hoppers, ensuring the safety of the recovery process. The device has a compact structure, meets the installation requirements of confined spaces, and is completely suitable for on-site installation. The components are simple and easy to install. The components operating in spaces with high explosion-proof requirements have low energy consumption, and there are no complex control components and live operating components, ensuring safety in the space.

[0029] Example 2

[0030] Different from the first embodiment, Figure 2 As shown, one end of each of the vacuum cylinders connected to the corresponding hopper is provided with a raised portion 25; the width of the raised portion 25 along the vacuum path is consistent.

[0031] The feeding port of a conventional hopper is relatively close to the open end, so a raised portion 25 is provided so that when extracting the material at the open end, the raised portion 25 forms a buffer zone, reduces the suction force at the open end, and avoids extracting the fed material, thereby ensuring high recovery efficiency while having no impact on the fed material itself.

[0032] The above description is merely an embodiment of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. A person of ordinary skill in the art is aware of all common technical knowledge in the technical field to which the utility model belongs before the application date or priority date, is able to obtain all existing technologies in the field, and has the ability to apply conventional experimental means before that date. A person of ordinary skill in the art can, under the guidance of this application, improve and implement the present scheme in combination with his or her own abilities. Some typical known structures or methods should not become an obstacle for a person of ordinary skill in the art to implement the present application. It should be pointed out that a person of ordinary skill in the art can make several variations and improvements without departing from the structure of the present invention. These should also be considered as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
