Description

Technical Field

[0001] This utility model relates to the field of impurity removal technology, and in particular to an impurity removal and stirring device for corn cob raw materials used in the production of functional sugars. Background Technology

[0002] In the production of functional sugars, corn cobs are an important raw material, and their pretreatment is crucial. Currently, corn cobs are a byproduct of farmers harvesting honey corn kernels, stored outdoors in a relatively crude manner. Debris such as plastic sheeting, waste plastic film, stretch film, and rags may be blown into the material by the wind. Additionally, some corn cobs are mixed into the material during collection and transportation using temporary packaging materials such as plastic bags, mesh bags, and cloth bags, as well as tying ropes. Entering the production system can cause severe blockages in pipes and pumps, leading to shutdowns and production disruptions. Therefore, it is necessary to thoroughly remove impurities from the material to ensure smooth production.

[0003] Traditional corn cob pretreatment methods often use simple screening or air and water separation to remove impurities, but these methods often have many drawbacks.

[0004] Screening methods can only remove larger particulate impurities, and are ineffective at removing small plastic fragments, fibers, and other impurities. Air separation can only remove some lightweight and relatively broken small impurities, while temporary packaging materials such as plastic bags, mesh bags, and cloth bags are easily entangled or hooked onto corn cobs, making it difficult to effectively separate these impurities using air separation. This deficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a stirring device for removing impurities from corn cob raw materials used in the production of functional sugars.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A stirring device for removing impurities from corn cob raw materials used in the production of functional sugars, comprising:

[0008] The tank is vertically arranged, with a feed inlet on one side of the top and a discharge outlet at the bottom.

[0009] A switch valve is installed at the discharge port of the tank.

[0010] The mounting bracket is divided into two parts, one part is installed on the top of the tank and the other part is installed on the bottom of the tank.

[0011] The stirring device, installed in the middle of the mounting frame, is used to stir the corn cobs in the tank, so that the corn cobs in the tank are turned up and down while being stirred horizontally.

[0012] The impurity removal device consists of multiple units spaced circumferentially along the outside of the stirring device and mounted on a mounting frame; it is used to wrap around the impurities mixed in the corn cob, so that the impurities are separated from the corn cob.

[0013] Preferably, the stirring device includes:

[0014] The first rotating shaft is rotatably connected to the mounting bracket.

[0015] The bracket consists of multiple brackets arranged spirally at intervals along the first axis of rotation;

[0016] The main helical blades are securely connected to the support.

[0017] The secondary helical blade is mounted on the shaft of the first rotating shaft; the main helical blade and the secondary helical blade rotate in opposite directions.

[0018] The first drive motor is mounted on top of the mounting bracket and is driven by the first rotating shaft.

[0019] Preferably, the impurity removal device includes:

[0020] The second drive motor is mounted on the top of the mounting bracket;

[0021] The impurity removal shaft is located between the upper and lower parts of the mounting bracket, and the top of the impurity removal shaft is connected to the second drive motor.

[0022] The impurity removal shaft includes:

[0023] The bottom of the second rotating shaft is movably connected to a portion of the mounting bracket located at the bottom of the tank body;

[0024] Connecting sleeves, which are multiple sleeves spaced apart along the shaft of the second rotating shaft;

[0025] The fork hooks are multiple hooks spaced apart along the circumferential direction of the connecting sleeve.

[0026] Preferably, the second rotating shaft is detachably connected to the second drive motor via a connecting device; the connecting device includes:

[0027] The splined shaft has one end connected to the second drive motor; the other end and the shaft body are provided with annular bosses.

[0028] The spline sleeve has one end connected to the spline shaft via a corresponding spline engagement, and the other end connected to the top spline engagement of the second rotating shaft; the annular boss at the bottom of the spline shaft is used to prevent the spline sleeve from falling off.

[0029] A spring is located between the spline sleeve and the annular boss on the spline shaft body, and the spring is movably sleeved with the spline shaft.

[0030] Preferably, a lifting ring is provided on one side of the top of the second rotating shaft.

[0031] Preferably, the bottom of the tank is provided with multiple support legs spaced circumferentially.

[0032] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0033] (1) The mounting frame inside the tank of this utility model is divided into two parts: the top and the bottom. It serves as the mounting base for the stirring device and the impurity removal device. Its design is reasonable, and the bottom part adopts a hollow structure, which facilitates the smooth discharge of corn cobs from the tank, ensuring the continuity of the production process, avoiding the accumulation of raw materials in the tank, and improving production efficiency.

[0034] (2) The stirring device of this utility model is further defined as having a structure including a first rotating shaft, a main spiral blade and a secondary spiral blade. The main spiral blade and the secondary spiral blade rotate in opposite directions. The main spiral blade is mounted on the shaft of the first rotating shaft through a bracket and is kept at a certain distance from the shaft. This structure enhances the range and force of stirring, so that the corn cob can fully contact the impurity removal device. At the same time, the corn cob is circulated and stirred up and down in the tank, which effectively improves the impurity removal effect and fully explores the functional value of the device in the raw material pretreatment stage. It plays a key role in ensuring the raw material supply for the subsequent production of functional sugars.

[0035] (3) The impurity removal device of this utility model consists of a second drive motor, a second rotating shaft, a connecting sleeve and a fork hook. The second drive motor drives the impurity removal rotating shaft to rotate, so that temporary packaging materials such as plastic bags, net bags, cloth bags or tying ropes in the corn cob are wrapped around the fork hook, thereby separating the impurities from the corn cob. This impurity removal method is highly targeted and can effectively remove common impurities in corn cob, ensuring the purity of corn cob raw materials and laying the foundation for the production of qualified functional sugars. Moreover, the operator can clean the impurities on the fork hook regularly, which can maintain a good impurity removal effect and prevent impurities from falling off or breaking due to long-term friction and re-mixing into the corn cob, further improving the stability of raw material quality.

[0036] (4) The present invention further adopts a connecting device to realize a detachable transmission connection. This design facilitates the quick separation of impurities on the impurity removal shaft when cleaning them. It can also easily remove the impurity removal shaft from the tank for cleaning and maintenance operations by using a lifting ring and a crane. This greatly reduces the labor intensity of operators, improves maintenance efficiency, and shortens downtime. In addition, multiple impurity removal shafts can be set up, one for backup, which effectively avoids the situation of extending the impurity removal cycle due to maintenance, improves the continuity and flexibility of production, has high practical application value, and can meet the needs of continuous and efficient processing of corn cob raw materials in the production process of functional sugars.

[0048] Example 1:

[0049] Combined with appendix Figures 1-3 According to devices 5 and 6, a stirring and impurity-removing device for corn cob raw materials used in the production of functional sugars includes a tank 1, a stirring device 4, and an impurity-removing device 5. The tank 1 is vertically arranged with a feed inlet on one side of its top and a discharge outlet at its bottom. Multiple support legs 7 are spaced circumferentially along the bottom of the tank 1, providing stable support for the entire tank 1. A switch valve 2 is installed at the discharge outlet of the tank 1. The crushed corn cobs enter the tank 1 through the feed inlet, and after impurity removal, the switch valve 2 is opened to discharge the processed corn cobs.

[0050] The tank 1 is equipped with a mounting bracket 3, which is divided into two parts: one part is located at the top of the tank 1, and the other part is located at the bottom of the tank 1. The mounting bracket 3 mainly serves as the mounting base for the stirring device 4 and the impurity removal device 5. The part of the mounting bracket 3 located at the bottom of the tank 1 has a hollow structure so that the corn cobs can be smoothly discharged from the tank 1.

[0051] A stirring device 4 is installed at the center of the mounting frame 3. Its function is to stir the corn cobs in the tank 1, allowing the corn cobs to be tumbled up and down while being horizontally stirred. In this embodiment, the stirring device 4 can be an existing mature device.

[0052] On the mounting frame 3, multiple impurity removal devices 5 are arranged circumferentially at intervals along the outside of the stirring device 4. The function of the impurity removal device 5 is to wrap around the impurities mixed in the corn cob, thereby achieving the separation of impurities from the corn cob.

[0053] Specifically, as shown in Figures 5 and 6, the impurity removal device 5 consists of a second drive motor 5-1 and an impurity removal rotating shaft. The second drive motor 5-1 is mounted on the top of the mounting frame 3, and the impurity removal rotating shaft is located between the upper and lower parts of the mounting frame 3, with its top connected to the second drive motor 5-1. By driving the impurity removal rotating shaft to rotate using the second drive motor 5-1, temporary packaging materials such as plastic bags, mesh bags, and cloth bags, or binding ropes mixed in with the corn cob, are wrapped around the impurity removal rotating shaft, thereby achieving the separation of impurities from the corn cob.

[0054] The impurity removal shaft specifically includes a second shaft 5-2, a connecting sleeve 5-3, and a fork hook 5-4. The bottom of the second shaft 5-2 is movably inserted into the part of the mounting bracket 3 located at the bottom of the tank 1, and the top is driven by the second drive motor 5-1. The mounting bracket 3 can effectively ensure the stability of the second shaft 5-2 and the stirring device 4, preventing collisions or interference between them.

[0055] Multiple connecting sleeves 5-3 are spaced apart on the shaft of the second rotating shaft 5-2, and multiple hooks 5-4 are distributed circumferentially on the sleeves 5-3. When the second rotating shaft 5-2 rotates, it drives the connecting sleeves 5-3, which in turn drives the hooks 5-4 to rotate. During rotation, the hooks 5-4 continuously collect and entangle impurities in the corn cob. Operators can periodically clean the impurities on the hooks 5-4 to maintain good impurity removal effect, while preventing impurities on the hooks 5-4 from falling off or breaking due to prolonged friction in the corn cob.

[0056] Example 2:

[0057] Referring to Figures 1-4, a stirring device for removing impurities from corn cob raw materials used in the production of functional sugars is described. Compared to Embodiment 1, the structure of the stirring device 4 is more clearly defined. It includes a first rotating shaft 4-1, a main helical blade 4-3, and a secondary helical blade 4-4. The shaft of the first rotating shaft 4-1 is rotatably connected to the mounting frame 3, that is, both ends of the first rotating shaft 4-1 are rotatably connected to the upper and lower parts of the mounting frame 3, respectively. This design enhances stability.

[0058] As shown in Figure 4, the first rotating shaft 4-1 is supported by multiple brackets 4-2 arranged spirally at intervals along its axial direction. The main helical blades 4-3 are mounted on these brackets 4-2, and a certain distance is maintained between the main helical blades 4-3 and the first rotating shaft 4-1. At the same time, secondary helical blades 4-4 are also mounted on the first rotating shaft 4-1, and the main helical blades 4-3 and secondary helical blades 4-4 rotate in opposite directions.

[0059] A first drive motor 4-5 is mounted on the top of the mounting frame 3, and the first drive motor 4-5 is driven by the first rotating shaft 4-1. Starting the first drive motor 4-5 drives the first rotating shaft 4-1 to rotate, which in turn drives the main spiral blade 4-3 and the auxiliary spiral blade 4-4 to rotate, stirring and tumbling the corn cobs inside the tank 1. The main spiral blade 4-3 stirs the corn cobs, ensuring they make full contact with the impurity removal device 5, and simultaneously flips the corn cobs from the bottom of the tank 1 to the top. The auxiliary spiral blade 4-4 flips the corn cobs from the top of the tank 1 to the bottom, and this cycle repeats, effectively improving the impurity removal effect.

[0060] Example 3:

[0061] Referring to Figures 5 and 7, a stirring device for removing impurities from corn cob raw materials used in the production of functional sugars, based on Embodiment 1 or 2, wherein the second rotating shaft 5-2 is detachably connected to the second drive motor 5-1 via a connecting device 6.

[0062] Specifically, the connecting device 6 includes a splined shaft 6-1, a splined sleeve 6-2, and a spring 6-3. One end of the splined shaft 6-1 is connected to the second drive motor 5-1, and the other end and its shaft body are provided with annular bosses. One end of the splined sleeve 6-2 is splinedly connected to the splined shaft 6-1, and the other end is splinedly connected to the top of the second rotating shaft 5-2. The annular boss at the bottom of the splined shaft 6-1 serves to prevent the splined sleeve 6-2 from falling off. The spring 6-3 is installed between the annular bosses on the splined sleeve 6-2 and the shaft body of the splined shaft 6-1. The spring 6-3 is movably sleeved with the splined shaft 6-1, and its function is to press the splined sleeve 6-2, keeping it connected to the top of the second rotating shaft 5-2, thereby transmitting power to the second rotating shaft 5-2.

[0063] When it is necessary to clean the impurities on the impurity removal shaft, the corresponding second drive motor 5-1 can be stopped, and the spline sleeve 6-2 can be moved up to separate the second shaft 5-2 from the connecting device 6. Then, the second shaft 5-2 can be pulled up to separate it from the part of the mounting bracket 3 located at the bottom of the tank 1, so that the entire impurity removal shaft can be taken out of the tank 1 for easy cleaning and maintenance.

[0064] It should be noted that multiple impurity removal shafts can be set, one for backup and one for use. This can effectively shorten downtime and avoid prolonging the impurity removal cycle.

[0065] Furthermore, a lifting ring 5-5 is provided on one side of the top of the second rotating shaft 5-2. The second rotating shaft 5-2 can be lifted out of the tank body 1 by connecting the lifting ring 5-5 with the hook of the crane. This can reduce the labor intensity of the operators.

[0066] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
