Description

Technical Field

[0001] This utility model relates to the field of destoners, and more particularly to an automatic starch feeding device. Background Technology

[0002] In the production and processing of rice noodles, starch is used as an auxiliary material and can be mixed into the main ingredient, rice noodles, in a certain proportion to improve the taste and texture of the rice noodles.

[0003] In existing technologies, starch is prone to accumulating during storage due to moisture absorption and clumping or electrostatic adsorption, which can lead to poor discharge and affect the continuous supply of materials to subsequent processes. In addition, starch itself has poor fluidity, and the amount of material fed at any given time can vary, resulting in uneven feeding and causing deviations in the mixing ratio between starch and rice flour, thus affecting the consistency and quality of the product.

[0004] Therefore, how to achieve orderly storage, uniform distribution and efficient transportation of starch in a closed environment has become a key technical problem that needs to be solved to improve the automation level of rice noodle processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic starch feeding device that can continuously and uniformly feed starch.

[0006] To achieve this objective, the present invention adopts the following technical solution: an automatic starch feeding device, comprising a feeding bin, a first pneumatic conveyor, a first pneumatic conveying pipe, a storage bin, a distributing hopper, a vibrator, a discharge bin, a second pneumatic conveying pipe, and a second pneumatic conveyor;

[0007] The feeding hopper is used to receive the starch fed in. The bottom of the feeding hopper is connected to the top of the storage hopper through the first air conveying pipe.

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 4 As shown, this utility model embodiment provides an automatic starch feeding device, including a feeding bin 1, a first pneumatic conveyor 21, a first pneumatic conveying pipe 31, a storage bin 4, a distributing hopper 5, a vibrator 6, a discharge bin 7, a second pneumatic conveying pipe 32, and a second pneumatic conveyor 21; the feeding bin 1 is used to receive the fed starch, the bottom of the feeding bin 1 is connected to the top of the storage bin 4 through the first pneumatic conveying pipe 31, the first pneumatic conveyor 21 is connected to the first pneumatic conveying pipe 31, and the first pneumatic conveyor 21 is used to blow the starch in the first pneumatic conveying pipe 31 into the storage bin 4; the bottom of the feeding bin 1 is connected to the top of the storage bin 4 through the first pneumatic conveying pipe 31. Connected to the top of the storage silo 4 and driven by the first air conveyor 21, it can solve the problems of poor conveying and environmental pollution caused by the poor flowability and dustiness of starch materials during the conveying process. When starch is received in the feeding silo 1, the first air conveyor 21 is started. The positive pressure formed by the airflow conveys the starch in the feeding silo 1 along the first air conveying pipe 31 to the top of the storage silo 4 set at a high position, so as to realize the long-distance conveying of materials and avoid the problem of discontinuous feeding caused by gravity conveying. At the same time, the closed air conveying structure can effectively reduce the flying and waste of starch during the conveying process and improve the cleanliness of the workshop.

[0029] like Figure 3 As shown, the distributing hopper 5 is located at the bottom of the storage silo 4. The distributing hopper 5 has a conical structure and multiple distributing cavities 51 arranged circumferentially. The distributing cavities 51 are used to disperse the starch in the storage silo 4. The vibrator 6 is located on the side wall of the storage silo 4 and is used to drive the storage silo 4 to vibrate. The storage silo 4 can accumulate and store starch. Since starch itself has poor fluidity, it is easy to form accumulation at the bottom of the storage silo 4, affecting the continuity and uniformity of subsequent feeding. The distributing hopper 5 can use gravity to naturally guide the starch to the distributing cavities 51, realizing the initial dispersion of the material and preventing concentrated accumulation from blocking a single discharge port. The vibrator 6 can keep the starch in a loose state and improve the fluidity of the falling starch.

[0030] The top of the discharge bin 7 is connected to the bottom of the distribution hopper 5 via a first electric valve 81. The first electric valve 81 is used to control the opening or closing of the distribution hopper 5. The bottom of the discharge bin 7 is connected to the second air conveying pipe 32. The second air conveyor 21 is connected to the second air conveying pipe 32 and is used to blow out the starch conveyed into the second air conveying pipe 32. The first electric valve 81 can be opened as needed according to the system control signal to control a certain amount of starch to enter the discharge bin 7 below, so as to achieve precise adjustment of the feeding amount. The discharge bin 7 serves as a transfer buffer bin, which can temporarily store a certain amount of starch material to prevent material blockage or interruption caused by different rhythms of upstream and downstream processes. When the second air conveyor 21 is started, the starch can be conveyed to the downstream designated work station by positive pressure airflow through the second air conveying pipe 32.

[0031] like Figure 1 and Figure 2 As shown, the feeding hopper 1 is further equipped with a rotary level gauge 91 and a discharge valve 92. The rotary level gauge 91 is used to detect the starch accumulation height in the feeding hopper 1. The discharge valve 92 is located between the feeding hopper 1 and the first air conveying pipe 31. The rotary level gauge 91 is electrically connected to the discharge valve 92 through a controller. The rotary level gauge 91 contacts the material through a rotating probe. When the starch reaches a set height, the rotary level gauge 91 is blocked and triggers a signal, feeding back the current material level information to the controller. The controller can determine whether to open or close the discharge valve 92 based on the detection result. When the starch level is low, the discharge valve 92 is closed to prevent the first air conveyor 21 from running idle. When the material level reaches the set upper limit, the discharge valve 92 is opened, allowing the starch to smoothly enter the first air conveying pipe 31. In this way, material interruption or overfeeding caused by untimely manual judgment can be avoided, improving the operational stability of the equipment.

[0032] like Figure 4 As shown, it further includes a blowpipe 71, one end of which is connected to an external high-pressure airflow generator, and the other end extends into the inner wall of the material discharge bin 7. The blowpipe 71 is used to blow off the starch adhering to the inner wall of the material discharge bin 7. By releasing high-pressure airflow at regular intervals, the blowpipe 71 can locally sweep the inner wall of the material discharge bin 7, causing the adhering starch to quickly detach from the wall surface and return to the material flow, thereby preventing starch retention and clumping.

[0033] like Figure 4 As shown, the second air delivery pipe 32 is further provided with a second electric valve 82, which is used to control the opening or closing of the second air delivery pipe 32.

[0034] like Figure 2As shown, the feeding hopper 1 further includes a feeding port 10 on its side wall, and a flip-top plate 11 on the feeding port 10. The flip-top plate 11 is used to close or open the feeding port 10. The flip-top plate 11 can close the feeding port 10 when not feeding, to prevent external air or dust from entering the feeding hopper 1 and causing the starch to become damp or contaminated.

[0035] like Figure 2 As shown, the top of the feeding hopper 1 is further provided with a dust removal device 12, which is used to adsorb the dust generated during the feeding process to avoid environmental pollution and safety hazards caused by dust overflow.

[0036] like Figure 1 As shown, it further includes a climbing platform frame 100, which is located between the ground and the top of the storage bin 4, and is used for operators to climb.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
