Description

TECHNICAL FIELD

[0001] The utility model relates to a bean vermicelli equipment, specifically a closed conveying device of bean vermicelli raw materials. BACKGROUND

[0002] At present, peas or mung beans are the main raw materials for producing bean vermicelli. In the production process of bean vermicelli, the conveying of raw materials is one of the key links to ensure product quality. However, the traditional raw material conveying method has problems: the traditional conveying method is open, for example, the common form of manual carrying combined with simple conveying belt. Due to the lack of effective sealing measures, impurities are easily mixed in the conveying process. Whether it is dust, particulate matter in the production workshop environment, or other foreign matter, it is possible to enter the raw material conveying flow. Once these impurities are mixed in, not only will they directly affect the purity of pea or mung bean raw materials, but also may introduce uncontrollable quality risks in the subsequent processing process. The presence of impurities may interfere with the forming process of bean vermicelli, resulting in quality defects such as broken strands and rough surface of bean vermicelli. At the same time, impurities may also carry microorganisms, increasing the risk of product contamination, and thus affecting the edible safety of bean vermicelli.

[0003] In addition, the open conveying method has very limited control ability over the quality of raw materials. Due to the lack of accurate measurement and monitoring means, it is impossible to accurately grasp the flow, ratio and other key parameters of peas or mung beans in the conveying process. In the production of bean vermicelli, the accuracy of the ratio of raw materials is directly related to the quality characteristics such as taste and toughness of the product. The open conveying method cannot ensure that the amount of raw materials conveyed each time meets the precise requirements, which is easy to cause fluctuations in the quality of different batches of products, and cannot meet the strict requirements of modern production for product consistency and stability.

[0004] With the continuous development of the bean vermicelli market, consumers' requirements for the quality of bean vermicelli products are increasing, and they pay more and more attention to the purity and taste stability of the products. The traditional open conveying method has obviously lagged behind the needs of industry development, seriously restricting the improvement of product quality and market competitiveness of bean vermicelli production enterprises. Therefore, it is urgent to develop a bean vermicelli raw material conveying device that can effectively prevent impurities from being mixed in and achieve accurate quality control.

[0027] In the description of the utility model, it is necessary to explain, unless there is definite stipulation and limitation, the term "installation", "linkage", "communication" should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be direct connection, also can through the intermediate medium indirectly connect, can be two elements inside the communication.For ordinary skilled person in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0028] The following specific embodiments illustrate the embodiments of the utility model, and those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled person in the art without creative labor belong to the scope of protection of the utility model.

[0029] As Figures 1-4 The utility model discloses a closed type conveying device of vermicelli raw materials, including raw material storage tank 1, fluidization tank 2 and microporous fluidization board 3, the lower section of raw material storage tank 1 narrows and forms lower taper section 11, the lower end opening of lower taper section 11 is fixedly connected with upper flange 12, the upper end opening of fluidization tank 2 is fixedly connected with lower flange 21, and microporous fluidization board 3 is clamped between upper flange 12 and lower flange 21 and is fixed together by fastener, and the inner end of raw material conveying pipe 4 is sealed and passes through lower taper section 11 and is bent downward, and the opening is downward and is located above microporous fluidization board 3, and the inner end of high-pressure gas conveying pipe is sealed and passes through fluidization tank 2 and opens below microporous fluidization board 3.

[0030] The working principle of the embodiment is as follows:

[0031] First, the vermicelli raw materials such as peas or mung beans are added to the raw material storage tank 1. The lower section of the raw material storage tank 1 narrows to form a lower taper section 11, which facilitates the downward flow of the raw materials. The high-pressure gas conveying pipe introduces gas inward, and the gas blows out upward from below the microporous fluidization board 3 after passing through the fluidization tank 2. The inner end of the raw material conveying pipe 4 is sealed and passes through the lower taper section 11 and is bent downward, and its opening is downward and is located above the microporous fluidization board 3. When the gas blows out from the microporous fluidization board 3, the raw materials above the microporous fluidization board 3 form a fluidized state. In the fluidized state, the friction between the raw material particles is reduced, similar to a fluid, facilitating the transportation through the raw material conveying pipe 4.

[0032] In another preferred embodiment, the taper of the lower taper section 11 is less than 80°. A smaller taper allows the raw materials to flow downward more smoothly under the action of gravity, avoiding problems such as impact, splashing or blockage caused by excessive taper resulting in excessive raw material flow rate, ensuring the stability and continuity of the raw material conveying process; it helps the raw materials to flow more thoroughly to the micro-porous fluidization plate 3, reduces the residue of raw materials on the inner wall of the lower taper section 11 of the raw material storage tank 1, improves the utilization rate of raw materials, reduces production costs, and at the same time is also conducive to maintaining the cleanliness of the equipment interior, reducing problems such as deterioration and mold caused by raw material residue, thereby ensuring the quality and safety of the vermicelli product.

[0033] In another preferred embodiment, the raw material conveying pipe 4 is smoothly transitioned within the lower taper section 11. The smooth transition design can reduce the jamming and frictional resistance of the raw materials during conveying, allowing the raw materials to enter the raw material conveying pipe 4 more smoothly, avoiding raw material accumulation and pipe blockage due to the lack of smoothness at the pipe connection, ensuring the efficiency of the conveying process, improving the conveying efficiency and reducing energy consumption; it avoids damage to the peas or mung beans and other raw materials caused by the sudden change in flow direction and possible collisions when passing through the pipe connection, protects the integrity of the peas or mung beans, helps maintain the quality of the raw materials, and ensures that the taste and quality of the produced vermicelli are not affected.

[0034] In another preferred embodiment, the pore size of the micro-pores on the micro-porous fluidization plate 3 is smaller than the smallest particle size of the mung beans. Ensuring that the mung beans and other raw materials do not leak out of the micro-pores during fluidization, ensuring the stability and reliability of the fluidization effect, allowing gas to uniformly act on the raw material layer, achieving a good fluidization state, and facilitating subsequent conveying operations; since the pore size is smaller than the particle size of the mung beans, it can prevent mung bean particles or other impurities from entering the micro-pores and causing blockage, ensuring the smoothness of gas flow, reducing the frequency and cost of equipment maintenance, prolonging the service life of the micro-porous fluidization plate 3, and ensuring that the entire conveying device can operate stably for a long period of time.

[0035] In another preferred embodiment, the upper end of the raw material storage tank 1 is a raw material inlet, and the raw material inlet is sealed by a tank cover 10. The movable sealing tank cover 10 can effectively block dust, debris and other impurities from entering the raw material storage tank 1 during raw material addition, ensuring the purity of the raw materials and avoiding the impact of impurities on the quality of the vermicelli raw materials, thereby improving the quality stability of the vermicelli product. The movable design of the tank cover 10 facilitates the opening and closing of the raw material inlet by the operator, making it convenient to add raw materials and perform equipment inspection, maintenance and other operations, improving work efficiency, and also better controlling the amount and timing of raw material addition, which is conducive to precise production process management.

[0036] In another preferred embodiment, the raw material storage tank 1 is supported by 3 evenly distributed legs 13. The three evenly distributed legs 13 can provide a stable support structure for the raw material storage tank 1, ensuring that the equipment remains balanced during operation, reducing problems such as uneven distribution of raw materials, loose pipe connections, poor fluidization, and other problems caused by equipment shaking or tilting, ensuring the normal operation of the conveying device. The design of the legs 13 allows the raw material storage tank 1 to have a certain gap from the ground, making it easier to clean, inspect, and maintain the equipment below, such as cleaning spilled raw materials, inspecting pipe connections, maintaining the fluidization tank 2 and related components, etc. It is also beneficial for ventilation and moisture prevention, extending the service life of the equipment.

[0037] In another preferred embodiment, the micro-porous fluidization plate 3 is a downwardly arched spherical structure, and the center of the spherical structure is located on the central axis of the lower cone section 11 and the inner end of the raw material conveying pipe 4. This spherical structure design allows the gas to be blown out from below the micro-porous fluidization plate 3 to be more evenly distributed to the surrounding area, resulting in a more uniform fluidization state of the raw material above the fluidization plate, avoiding local poor fluidization or dead zone phenomena, ensuring that the raw material is well fluidized at all locations, which is beneficial for subsequent smooth conveying. The shape of the spherical structure helps to guide the fluidized raw material to naturally converge towards the central axis, that is, to flow towards the inner end of the raw material conveying pipe 4, improving the efficiency of raw material entering the conveying pipe, reducing the residence time of raw material on the fluidization plate, and further improving the overall working efficiency of the conveying device, ensuring that the raw material can be timely and smoothly conveyed to the next production link.

[0038] In another preferred embodiment, the inner end of the raw material conveying pipe 4 is expanded outward to form a flared mouth 41; the lower end of the fluidizing tank 2 is centrally provided with a threaded hole with an axial direction being upward and downward, the fluidizing tank 2 is screwed with the screw rod 6 through the threaded hole, the lower end of the screw rod 6 is located outside the fluidizing tank 2 and is fixedly connected with a non-circular rotating section 61, the upper end of the screw rod 6 is located inside the fluidizing tank 2 and is fixedly connected with a circular truncated cone 62 which is matched with the flared mouth 41, the gap between the flared mouth 41 and the circular truncated cone 62 can be adjusted by rotating the rotating section 61 counterclockwise or clockwise, so as to adjust the flow of the raw material conveying pipe 4; the screw rod 6 outside the fluidizing tank 2 is screwed with a back nut 7, and a flat washer 8 and a sealing rubber ring 9 are additionally arranged between the back nut 7 and the fluidizing tank 2. The gap between the flared mouth 41 and the circular truncated cone 62 can be adjusted by rotating the rotating section 61 counterclockwise or clockwise, so as to realize the accurate control of the flow of the raw material conveying pipe 4. This design can flexibly adjust the conveying amount of the raw materials of peas or mung beans according to the actual production requirements, so as to meet the accurate requirements of different production processes and product formulas on the proportioning of raw materials, and help to improve the stability and consistency of the quality of vermicelli products. In the process of producing vermicelli, different raw material conveying speeds may be required at different stages or for different products. The device can conveniently realize real-time flow adjustment during operation, without the need to stop the machine, replace the equipment or adjust the complex mechanical structure, so as to improve the production efficiency and reduce the production cost. The screw rod 6 outside the fluidizing tank 2 is screwed with the back nut 7, and the flat washer 8 and the sealing rubber ring 9 are additionally arranged between the back nut 7 and the fluidizing tank 2, so as to effectively enhance the sealing performance of the connection between the screw rod 6 and the fluidizing tank 2. This can prevent gas from leaking from the threaded hole, ensure that all the gas input by the high-pressure gas conveying pipe is used below the microporous fluidizing plate 3, make the raw material fluidization process stable and reliable, and avoid problems such as poor fluidization effect and poor raw material conveying caused by gas leakage. Good sealing performance can also prevent foreign matters from entering the inside of the fluidizing tank 2 through the threaded hole, further ensure the purity of the raw materials of vermicelli, avoid the mixing of foreign matters into the raw materials of vermicelli to adversely affect the quality of vermicelli, and help to prolong the service life of the internal components of the equipment and reduce the equipment failure and maintenance cost caused by the entry of foreign matters. The entire flow adjustment mechanism is integrated at the lower end of the fluidizing tank 2, so as to have a compact structure and not occupy too much space, which is coordinated with the design of the overall closed conveying device, is convenient for the layout and installation of the equipment, and enables the operator to realize flow adjustment only by rotating the non-circular rotating section 61, so as to have simple and convenient operation, without the need for professional skills and complex tools, be easy to master and use, reduce the labor intensity, and improve the convenience and operability of production operation.

[0039] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
