Description

Technical Field

[0001] This utility model belongs to the technical field of proportional control of liquid mixtures, specifically relating to an automatic control device for slurry concentration in rice noodle production lines. Background Technology

[0002] In the rice noodle production process, the stability of the slurry concentration directly affects the product quality and taste. With the increasing demand for automation upgrades in the food industry, automatic control devices monitor slurry parameters in real time and dynamically adjust the water-to-powder ratio to achieve standardized control of the production process. These devices are usually integrated into the mixing system or conveying pipeline in the rice noodle production line, becoming a key component of modern rice noodle processing equipment.

[0003] Currently, starch in slurry tends to gradually deposit and clump on the surface of the sensor probe, forming a layer of deposit. This deposit interferes with the sensor's accurate detection of slurry concentration, causing reading deviations. Because the deposition process is slow and not easily detected in the early stages, the control system may continuously receive incorrect concentration signals for a period of time. It will only be detected when the deposition becomes severe enough, at which point it has already had a potential impact on product quality. Utility Model Content

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0019] Reference Figures 1-5 This embodiment of the present invention provides an automatic control device for the slurry concentration of a rice noodle production line, comprising: The support mechanism 100 includes a tank 110 and a stirring assembly 120 disposed on the top of the tank 110; The automatic cleaning mechanism 200 includes a slow-speed bushing 210, a connecting rod 220 fixedly installed on the outside of the slow-speed bushing 210, a trough plate 230 fixedly installed in the inner cavity of the mixing assembly 120, and a cleaning brush head 240 fixedly installed on the top of the connecting rod 220.

[0020] By setting up a linkage structure between the automatic cleaning mechanism 200 and the stirring assembly 120, the online cleaning function of the concentration sensor 145 can be realized. The slow-speed bushing 210 drives the connecting rod 220 to perform periodic rotation, so that the cleaning brush head 240 mechanically scrapes the sensor surface along the trajectory defined by the trough plate 230, effectively preventing detection deviation caused by slurry deposition.

[0021] Specifically, the automatic cleaning mechanism 200 also includes a bearing 250 fixedly installed at the end of the connecting rod 220, a gear 260 hinged in the inner cavity of the bearing 250, and a spring rod 270 movably locked at the center of the top of the gear 260 for limiting its position.

[0022] The buffer limiting mechanism formed by gear 260 and spring rod 270 enables the cleaning brush head 240 to have an adaptive clamping force when it contacts the sensor. The bearing 250 provides a stable rotation fulcrum, and the elastic deformation characteristics of spring rod 270 can compensate for the wear of the brush head, ensuring the long-lasting effectiveness of the cleaning action.

[0023] It should be noted that the design of the gear 260 and the groove plate 230 forms a unique biomimetic cleaning mechanism. When the gear 260 rotates along the groove surface of the groove plate 230, the periodic radial displacement generated by the meshing of the two forces the connecting rod 220 to swing with a controllable amplitude. This dynamic and irregular mechanical motion is transformed into the composite motion trajectory of the cleaning brush head 240, so that when it contacts the surface of the concentration sensor 145, it forms a reciprocating micro-oscillation motion similar to manual brushing. This not only enhances the peeling effect of deposits, but also avoids cleaning dead corners caused by unidirectional scraping, and improves the removal rate of stubborn clumps.

[0024] Furthermore, the supporting mechanism 100 also includes a discharge component 130 disposed on the outside of the mixing assembly 120, a detection component 140 disposed on the top of the mixing assembly 120, and a connecting pipe 150 fixedly installed on the top of the mixing assembly 120.

[0025] The integrated layout of the discharge component 130, the detection component 140 and the connecting pipe 150 forms a closed-loop control system. The detection component 140 collects the slurry parameters in the mixing cylinder 121 in real time, the discharge component 130 performs precise discharge, and the connecting pipe 150 realizes the fluid connection of each functional module.

[0026] Preferably, the stirring assembly 120 includes a mixing cylinder 121 fixedly installed on the top of the tank 110, a shaft 122 hinged to the inner cavity of the mixing cylinder 121, a ring 123 fixedly installed on the outside of the shaft 122, and a support rod 124 fixedly installed on the outside of the ring 123. The stirring assembly 120 also includes a scraper 125 fixedly installed on the end of the support rod 124, a stirring rod 126 fixedly installed on the outside of the support rod 124, and a drive motor 127 fixedly installed on the top of the mixing cylinder 121. The output end of the drive motor 127 is fixedly connected to the top of the shaft 122.

[0027] The stirring assembly 120 adopts a nested structure of shaft 122 and ring 123, and the support rods 124 are radially distributed to form a three-dimensional stirring network, so that the slurry forms a three-dimensional turbulent flow in the mixing cylinder 121, which improves the uniformity of powder-liquid mixing and creates a stable flow field environment for concentration detection. It is equipped with a combination structure of scraper 125 and stirring rod 126. The scraper 125 moves close to the inner wall of the mixing cylinder 121 to prevent material adhesion, and the stirring rod 126 generates axial shear flow. The drive motor 127 transmits compound torque through shaft 122 to achieve efficient and low-resistance stirring.

[0028] Furthermore, the detection assembly 140 includes a tube head 141 fixedly installed on the top of the mixing cylinder 121, a metering pump 142 fixedly installed on the top of the tube head 141, a regulating valve 143 fixedly installed on the outside of the metering pump 142, a delivery pipe 144 fixedly installed on the outside of the regulating valve 143, and a concentration sensor 145 fixedly installed on the bottom of the tube head 141 and extending into the inner cavity of the mixing cylinder 121. The top of the cleaning brush head 240 is in contact with the bottom of the concentration sensor 145, and the cleaning brush head 240 adopts a detachable design.

[0029] The detection component 140 uses a recessed tube head 141 to install a concentration sensor 145. The metering pump 142 and the regulating valve 143 form a precise slurry sampling system. The delivery pipeline 144 ensures the flow and renewal of the detection medium. The dynamic contact design between the cleaning brush head 240 and the sensor end face makes the detection process both real-time and reliable.

[0030] Furthermore, the discharge assembly 130 includes a housing 131 fixedly installed on the outside of the mixing cylinder 121, a cylinder 132 fixedly installed on the outside of the housing 131, a valve plate 133 fixedly installed on the output end of the cylinder 132, and a discharge pipe 134 fixedly installed on the bottom of the housing 131.

[0031] Among them, the discharge component 130 drives the valve plate 133 to move linearly through the cylinder 132, realizing the rapid opening and closing of the box 131 and the discharge pipe 134 channel. This solves the problem of traditional butterfly valves being prone to jamming in viscous slurry, and has the characteristics of rapid response and reliable sealing. It is especially suitable for intermittent production processes.

[0032] In use, after the drive motor 127 starts, it drives the shaft 122 to rotate. The slurry in the mixing drum 121 is fully stirred by the stirring rod 126 and the scraper 125. The concentration sensor 145 detects the slurry concentration data in real time. At the same time, the automatic cleaning mechanism 200 drives the cleaning brush head 240 to perform biomimetic cleaning of the sensor through the meshing action of the gear 260 and the trough plate 230. The detection data is transmitted to the control system through the sampling system composed of the metering pump 142 and the regulating valve 143. When the concentration reaches the set value, the cylinder 132 drives the valve plate 133 to open the discharge pipe 134 for precise discharge. The whole process forms an automated closed-loop control of stirring, detection, cleaning and regulation.

[0033] In summary, the mixing component 120 forms a uniform flow field through a three-dimensional mixing network, the detection component 140 collects slurry parameters in real time and maintains sensor accuracy through an automatic cleaning mechanism 200, and the discharge component 130 achieves precise flow control. The innovative linkage mechanism between the gear 260 and the trough plate 230 enables the cleaning brush head 240 to produce a composite motion that mimics human movement. Combined with the anti-stick design of the scraper 125 and the mixing rod 126, this not only ensures the reliability of the detection data but also improves the accuracy and stability of concentration control while maintaining the continuity of the production process.
