Description

Technical Field

[0001] This utility model relates to rice noodle processing equipment, specifically a rice slurry mixing device for a small rice noodle machine. Background Technology

[0002] In the production of rice noodles using small rice noodle machines, the uniformity of rice slurry mixing, the accuracy of the feeding ratio, and the stability of conveying directly affect the final product quality and production efficiency.

[0003] Existing rice slurry mixing devices have many shortcomings:

[0004] First, the mixing structure is simple, mostly driven by a motor to rotate a single mixing blade in the center of the tank. This can only mix the rice slurry in the center of the tank. The rice slurry far from the mixing center is not mixed sufficiently, which easily leads to uneven concentration of the mixture and seriously affects the quality of the finished rice slurry.

[0005] Secondly, the feeding process relies on manual experience, and the ratio of rice powder to water has a large error, resulting in batch quality fluctuations.

[0006] Third, the delivery pump is prone to clogging, and the rice slurry is prone to separation.

[0007] Fourth, the mixing volume does not match the material supply requirements of the extruder, often resulting in oversupply or undersupply, which restricts the continuity of production.

[0033] (3) Precise and stable material supply

[0034] The level sensor in the secondary mixing tank is linked with the flexible pump to ensure a stable level of rice slurry in the secondary mixing tank. The flexible pump is less prone to clogging and has a high degree of compatibility with the rice noodle extruder's feeding, thus improving production continuity.

[0052] The present invention will be further described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention. Example

[0053] like Figures 1-6 As shown, a rice slurry mixing device for a small rice noodle machine includes a mixing component, which comprises a two-stage mixing component consisting of a main mixing tank component 1 and a secondary mixing tank component 3.

[0054] The main mixing tank component 1 includes a tank body 1-1, a first motor 1-8, a main mixing shaft 1-10, and multiple layers of blades; wherein, the main mixing shaft 1-10 is vertically installed inside the tank body 1-1; the multiple layers of blades are arranged on the main mixing shaft 1-10; the multiple layers of blades include at least two layers of blades arranged with different thread inclination directions, including a first layer of blades 1-11 and a second layer of blades 1-12; the first motor 1-8 drives the main mixing shaft 1-10 to rotate the multiple layers of blades, thereby rotating the first layer of blades 1-11 and the second layer of blades 1-12, so as to achieve the mixing effect of the rice slurry circulating up and down;

[0055] The secondary mixing tank component 3 includes a secondary tank body 3-3, a second motor 3-1, a secondary mixing shaft 3-9, and secondary impellers 3-10. The secondary mixing shaft 3-9 is vertically installed inside the secondary tank body 3-3, and the secondary impellers 3-10 are fixedly installed on the secondary mixing shaft 3-9. The secondary impellers 3-10 are provided with multiple staggered crossbars 3-12. The second motor 3-1 drives the secondary mixing shaft 3-9 to rotate, thereby driving the secondary impellers 3-10 to rotate to prevent rice slurry sedimentation.

[0056] The tank 1-1 and the secondary tank 3-3 are connected by a connecting pipe 6, and the connecting pipe 6 is equipped with a flexible pump 2 and a solenoid valve 5.

[0057] like Figure 3 As shown, the first layer of blades 1-11 forms an angle of 35° with the axis of the main stirring shaft 1-10; the second layer of blades 1-12 forms an angle of 15° with the axis of the main stirring shaft 1-10.

[0058] like Figure 1 Figure 2 As shown, the upper section of the tank 1-1 is cylindrical, and the lower section of the tank in this embodiment is an arc-shaped bottom. The top of the tank 1-1 is provided with an upper cover plate 1-6, which is fixed to the tank 1-1 by a buckle 1-4 provided on the tank 1-1. The first motor 1-8 is provided on the upper cover plate 1-6.

[0059] The upper side wall of the tank 1-1 is provided with a water inlet pipe 1-9 and a first liquid level sensor 1-3, and the bottom of the tank 1-1 is provided with a first slurry outlet pipe 1-16; the water inlet pipe 1-9 is connected to the water inlet pipe, and the water inlet pipe is provided with a water inlet pump 8 and a flow meter 7.

[0060] The upper side wall of the tank 1-1 is provided with a limit sensor 1-2;

[0061] The upper cover plate 1-6 is provided with a detection plate 1-7, which cooperates with the limit sensor 1-2.

[0062] like Figure 3 As shown, it includes a main impeller 1-13, which is U-shaped. The two sides of the U-shape are adapted to the shape of the inner wall of the upper section of the tank 1-1, and the bottom of the U-shape is adapted to the shape of the inner wall of the lower section of the tank 1-1. The two sides of the U-shaped main impeller are connected to the outer ends of the first layer blade 1-11 and the second layer blade 1-12, and the inner ends of the first layer blade 1-11 and the second layer blade 1-12 are connected to the main stirring shaft 1-10 to form a closed frame.

[0063] Furthermore, it includes a scraper 1-14, which is disposed on the outer side of the main paddle 1-13. The scraper 1-14 is made of a food-grade rubber material with a certain degree of elasticity. One end of the scraper 1-14 directly contacts the inner wall of the tank. When the main paddle 1-13 rotates, it drives the scraper 1-14 to scrape the slurry off the inner wall of the tank 1-1.

[0064] Furthermore, the scraper blades 1-14 are arranged in a staggered manner on the main blades 1-13.

[0065] Furthermore, the upper cover plate 1-6 is detachable, with the detachment hinged. The detachment of the upper cover plate 1-6 is hinged by hinges 1-5, and multiple fasteners 1-4 are distributed along the edge of the upper cover plate 1-6 for fixing the upper cover plate 1-6 to the tank body 1-1, such as... Figure 1 Figure 2 As shown, the disconnection is set at two points, dividing the upper cover plate 1-6 into three sections. The first motor 1-8 is installed on the second section of the upper cover plate, which is fixed to the tank body 1-1. When it is necessary to open or close the upper cover plate 1-6, the corresponding latches can be operated to open or close the first and third sections of the upper cover plate that are hinged to the second section. This structure ensures that opening and closing the upper cover plate will not affect the first motor 1-8 installed on the second section of the upper cover plate and the main stirring shaft 1-10 connected to it.

[0066] The upper section of the tank (1-1) is cylindrical, made of food-grade stainless steel with a wall thickness of 3.0-5.0mm, exhibiting good corrosion resistance and strength. The lower section has an arc-shaped or conical bottom, formed by die stamping and then welded to the cylindrical section. The arc-shaped bottom facilitates flow and is easy to manufacture; the conical bottom has a cone angle greater than 60°, formed by cutting and welding sheet metal. The inner wall of the tank is polished to a roughness ≤Ra1.6μm, ensuring that rice slurry does not easily adhere and is easy to clean, facilitating complete material drainage.

[0067] The tank body 1-1 has a height of 800mm, and the water inlet pipe 1-9 is 50mm-100mm from the top of the tank body 1-1. The first liquid level sensor 1-3 is used to detect the liquid level of the rice slurry. When the liquid level reaches the preset value of the position of the first liquid level sensor 1-3, the main control module controls the water inlet pump 8 to stop adding water. The edge of the upper cover plate 1-6 is fixedly connected to the detection plate 1-7, and the lower end of the detection plate 1-7 is attached to the limit sensor 1-2. The limit sensor 1-2 is fixedly connected to the outer wall of the tank body 1-1. When the upper cover plate 1-6 is opened at an angle greater than 15°, the detection plate 1-7 moves with the opened upper cover plate. When the limit sensor 1-2 changes from being attached to the detection plate to being detached, the main control module immediately cuts off the power to the first motor 1-8. Only when the upper cover plate 1-6 is closed and locked, and the lower end of the detection plate 1-7 is attached to the limit sensor 1-2, can the first motor 1-8 be started to prevent slurry splashing and foreign objects from entering.

[0068] like Figure 3 As shown, the main stirring shaft 1-10 passes through multiple first shaft sleeves 1-15 and is fixedly installed with the first shaft sleeves 1-15. The stirring blades are radially fixedly installed on the first shaft sleeves 1-15. The blades have a rectangular cross-section. The stirring blades, from top to bottom, are arranged in a first layer of blades 1-11 and a second layer of blades 1-12. The angle between the first layer of blades 1-11 and the axis of the main stirring shaft 1-10 is 30°-45°, and in this embodiment, it is 35°. The thread of the blades is left-handed, similar to a left-hand thread; that is, when viewed from the axis of the stirring shaft, the blades appear to be spiraling to the left. The blades are tilted in the direction of rotation. When the main stirring shaft 1-10 is driven to rotate clockwise, the material in the tank exerts a downward thrust on the material when it comes into contact with the inclined surface of the first layer of blades 1-11. The angle between the second layer of blades 1-12 and the axis of the main stirring shaft 1-10 is 10°-20°, which is 15° in this embodiment. The blades are tilted in the direction of right-hand thread, similar to a right-hand thread. That is, when viewed from the axis of the stirring shaft, the blades are tilted in the direction of "right-hand spiral". When the main stirring shaft 1-10 is driven to rotate clockwise, the material in the tank exerts an upward thrust on the material when it comes into contact with the inclined surface of the second layer of blades 1-12.

[0069] A third layer of blades 1-17 can also be installed. The spiral inclination direction of the third layer blades 1-17 is consistent with that of the adjacent second layer blades 1-12. The cooperation of multiple layers of blades creates an up-and-down circulation of materials, thereby enhancing the mixing effect. The upper layer of materials is pushed downwards, and the lower layer of materials is pushed upwards, which can prevent local accumulation of materials in the tank 1-1 and enhance the mixing uniformity of materials at different depths. The first layer has a larger included angle, 30°-45°, with a more significant downward thrust, which is suitable for driving the upper layer of materials to move downwards quickly. The second layer has a smaller included angle, 10°-20°, with a gentler upward thrust, which can balance the flow speed of the lower layer of materials and avoid excessive local turbulence or wasted power. Through the difference in spiral direction and blade inclination angle, the material is circulated back and forth in the axial direction, enhancing the mixing effect.

[0070] The outer ends of the first layer blades 1-11 and the second layer blades 1-12 are fixedly connected to the main blade 1-13 to form a closed frame. The bottom of the main blade 1-13 is curved in an arc shape, perfectly matching the cross-section of the lower section of the tank body 1-1. The rigid structure of the closed frame can disperse the resistance of the material to the blades, especially when stirring high-viscosity materials, it can withstand large radial and axial forces, ensuring long-term stable operation.

[0071] Multiple scraper blades 1-14 are fixedly installed on the main impeller blades 1-13, and the scraper blades 1-14 are staggered with each other. When the main stirring shaft 1-10 rotates, it can cover the bottom and side wall area of ​​the tank 1-1 to the maximum extent. The scraper blades 1-14 are close to the inner wall of the tank 1-1, which eliminates the "dead zone" on the wall that is difficult for traditional agitators to reach, thereby improving the scraping ability and efficiency.

[0072] The lower end of the tank body 1-1 is provided with a first slurry outlet pipe 1-16, which is connected to a solenoid valve 5. The solenoid valve 5 is fixedly connected to a connecting pipe 6, and the other end of the connecting pipe 6 is fixedly connected to the slurry inlet of the flexible pump 2. The slurry outlet of the flexible pump 2 is fixedly connected to the slurry inlet pipe 3-4 of the secondary mixing tank component 3.

[0073] The secondary tank 3-3 has a straight cylindrical upper section and a curved or conical bottom lower section, such as... Figure 4 As shown, this embodiment uses a conical bottom. The curved bottom facilitates the flow field and is easy to manufacture. The cone angle of the conical bottom is greater than 60°, which is more conducive to the complete emptying of materials. It is made of 304 food-grade stainless steel, and its structure is similar to that of the main mixing tank. The inner wall is also polished.

[0074] The slurry inlet pipe 3-4 is connected to the connecting pipe 6 of the main mixing tank component 1.

[0075] The secondary impeller 3-10 is U-shaped, and the shapes of the sides and bottom of the U-shaped secondary impeller 3-10 are adapted to the shape of the inner wall of the secondary tank 3-3; the secondary impeller 3-10 is connected to the secondary stirring shaft 3-9 through the crossbar 3-12.

[0076] The secondary stirring shaft 3-9 passes through the second shaft sleeve 3-11. Multiple crossbars 3-12 are staggered and connect the secondary blades 3-10 to the secondary stirring shaft 3-9 and the second shaft sleeve 3-11 to form a closed connection. The overall frame is based on the inner wall contour of the secondary tank 3-3, and the overall mixing is achieved during rotational stirring.

[0077] The secondary tank 3-3 has a support plate 3-2 at its top, and the second motor 3-1 is mounted on the support plate 3-2. The support plate 3-2 has an inlet pipe 3-4. The secondary tank 3-3 has a second outlet pipe 3-8 at its bottom, which is fixedly connected to the inlet pipe of the rice noodle extruder 4. The second motor 3-1 is connected to the secondary stirring shaft 3-9 via a coupling 3-5.

[0078] It includes a second liquid level sensor 3-6 and a third liquid level sensor 3-7; the second liquid level sensor 3-6 is disposed on the upper side wall of the secondary tank 3-3; the third liquid level sensor 3-7 is disposed on the lower side wall of the secondary tank 3-3.

[0079] When the liquid level is higher than the second liquid level sensor 3-6, the main control module immediately closes the solenoid valve 5, cuts off the power to the flexible pump 2, and stops feeding; when the liquid level is lower than the third liquid level sensor 3-7, the main control module immediately opens the solenoid valve 5 and starts the flexible pump 2 to replenish the material.

[0080] like Figure 6 As shown, the system includes a main control module, which is electrically connected to an input module and an output module. The input module is electrically connected to limit sensors 1-2, a first liquid level sensor 1-3, a second liquid level sensor 3-6, and a third liquid level sensor 3-7. The output module is electrically connected to a motor driver, which is electrically connected to a first motor 1-8, a second motor 3-1, a solenoid valve 5, and a flexible pump 2. The output module is sequentially connected to the water inlet pump 8 and a flow meter 7. The output module is also electrically connected to a rice noodle extruder 4. The main control module is connected to a power supply module.

[0081] The working process of the rice slurry mixing device includes the following steps:

[0082] 1. Feeding stage

[0083] The operator opens the upper cover 1-6 of the main mixing tank component 1, unlocks the latch 1-4, and the upper cover 1-6 opens around the hinge 1-5. At this time, because the opening angle of the upper cover 1-6 is greater than 15°, the detection plate 1-7 disengages from the limit sensor 1-2, triggering the limit sensor 1-2 to transmit the opening signal to the main control module. The main control module cuts off the power to the first motor 1-8 and stops the mixing.

[0084] After the bagged rice powder is poured into the can 1-1, the top cover 1-6 is closed and locked with the buckle 1-4. The detection plate 1-7 contacts the limit sensor 1-2, triggering the limit sensor 1-2 to transmit the closing signal to the main control module. The main control module then connects the power supply to the first motor 1-8.

[0085] The operator presses the "Pre-fill Water" button connected to the main control module, turns on the water pump 8 to inject water into the tank 1-1 through the water inlet pipe 1-9, and the first liquid level sensor 1-3 monitors the liquid level in real time. When the preset pre-fill water volume is reached, the main control module controls the water pump 8 to stop adding water.

[0086] The main control module automatically calculates the amount of water to be added based on the amount of rice powder added, and precisely controls the water addition through water inlet pipes 1-9, water pump 8, and flow meter 7.

[0087] 2. Main mixing stage

[0088] Low-speed mixing: The first motor 1-8 drives the main stirring shaft 1-10 to rotate clockwise. The first layer of blades 1-11 with the left-hand spiral generates a downward pushing force on the upper layer of material, and the second layer of blades 1-12 with the right-hand spiral generates an upward pushing force on the lower layer of material, forming an up-and-down circulation to initially mix rice powder and water, avoiding dust flying.

[0089] High-speed homogenization: The main stirring shaft 1-10 rotates clockwise, the multi-layer blades enhance the circulation intensity, the bottom arc of the main blade 1-13 fits the lower section of the tank 1-1, and the scraper 1-14 scrapes off the adhering material from the inner wall of the tank 1-1, eliminating dead zones on the wall.

[0090] Anti-settling slowdown: The first motor 1-8 maintains low-speed rotation to keep the rice slurry uniform after mixing, waiting for the pumping command;

[0091] 3. Pumping stage

[0092] When the liquid level in the secondary tank 3-3 of the secondary mixing tank component 3 is lower than the third liquid level sensor 3-7, the third liquid level sensor 3-7 transmits a signal to the main control module, the main control module starts the flexible pump 2 and opens the solenoid valve 5 at the same time to start conveying rice slurry to the secondary mixing tank;

[0093] 4. Secondary mixing and feeding

[0094] The second motor 3-1 drives the secondary stirring shaft 3-9 to rotate. The crossbar 3-12 on the secondary blade 3-10 works in conjunction with the blade to stir the rice slurry in the secondary tank 3-3 and prevent sedimentation.

[0095] When the liquid level in the secondary tank 3-3 is higher than the second liquid level sensor 3-6, the second liquid level sensor 3-6 transmits a signal to the main control module, and the main control module shuts down the flexible pump 2 and the solenoid valve 5 to stop feeding; when the liquid level is lower than the third liquid level sensor 3-7, the pumping stage operation is repeated to feed.

[0096] 5. The rice slurry flows from the second slurry outlet pipe 3-8 into the rice noodle extruder 4, completing the extrusion and forming of rice noodles.

[0097] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
