Description

Technical Field

[0001] The utility model relates to the technical field of soybean milk manufacturing and processing equipment, in particular to a detection device for the concentration of soybean milk. Background Art

[0002] In the production process of soy milk products, the concentration of soy milk needs to be tested. Accurate control of soy milk concentration is crucial to ensure product quality. Traditional soy milk concentration detection methods often rely on manual sampling and offline analysis, which is not only inefficient but also difficult to reflect the changes in soy milk concentration in real time.

[0003] The existing automatic pulp concentration detection device requires manual pulp addition when the concentration is not enough. In addition, due to the influence of factors such as precipitation and impurities produced during the storage and transportation of the pulp, it cannot be fully mixed after water injection, which easily leads to uneven concentration detection. Utility Model Content

[0004] In order to solve the existing technical problem of uneven concentration detection, the utility model provides a slurry concentration detection device.

[0011] Through the above technical scheme, the slurry level detection device installed in the slurry outlet section monitors the liquid level of the slurry in real time to ensure that the slurry maintains an appropriate liquid level during the filtration process to avoid overflow or insufficiency. The inspection doors on both sides can conveniently maintain the driving device to ensure the long-term stable operation of the equipment. The filter plate can be driven by the driving device to complete rapid up and down lifting.

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0029] A device for detecting pulp concentration, such as Figure 1-6 As shown, it includes a control panel, a slurry inlet pipeline, a slurry return pipeline 2, a filter box 3 and a slurry storage box 5. The slurry inlet pipeline is connected to the filter box 3. The filter box 3 is provided with a slurry return pipeline 2. The filter box 3 is connected to the slurry storage box 5 through a slurry delivery pipeline arranged thereon. The slurry storage box 5 is provided with a concentration detector 8 and a stirring shaft 7. The slurry storage box 5 is connected with a slurry outlet pipeline and a water injection pipeline. A proportional valve 1 is provided on the slurry inlet pipeline and the water injection pipeline. A filter plate 32 can be pulled out on the filter box 3. The pullable design of the filter plate 32 makes the filtering operation more convenient. When the filter plate 32 is blocked, it can be easily pulled out for cleaning or replacement. The filter box 3 accommodating chamber is divided into a slurry inlet part and an outlet part by the filter plate 32. The slurry section and the slurry outlet section are connected to the slurry inlet section through the slurry return pipe 2, and secondary filtration is performed through the slurry return pipe 2 to improve the efficiency and quality of subsequent processing. After the filtration is completed, the slurry (soy milk) enters the slurry storage box 5 through the slurry delivery pipe, and the overall concentration of the slurry is adjusted in conjunction with the water injection pipe. The slurry return pipe 2, the slurry delivery pipe, and the slurry outlet pipe are all installed with a sanitary pump 10. The sanitary pump 10, the proportional valve 1, and the concentration detector 8 are all communicatively connected to the control panel. When the concentration is too high or too low, the control panel can automatically adjust the proportional valve 1 on the slurry inlet pipe and the water injection pipe according to the preset parameters, thereby controlling the ratio of slurry inlet and water injection to achieve the expected concentration, effectively improving production efficiency and product quality.

[0030] The filter box 3 includes a box body 31, a cover 33 and a slot 34. The box body 31 is provided with a slot 34. The filter plate 32 can be pulled out and set in the slot 34. The cover 33 is snap-fitted into the slot 34. The accommodating chamber in the filter box 3 is divided into a pulp inlet portion and a pulp outlet portion by the filter plate 32. The pulp inlet portion is located above the pulp outlet portion. A pulp level detection device 6 is installed in the pulp outlet portion. The inner wall of the box body 31 is located below the pushing device 4. The pulp level detection device 6 is a water level detector to prevent the soybean milk height in the pulp outlet portion from being too high, thereby preventing the soybean milk from penetrating into the pushing device 4 and affecting the pushing device 4, thereby ensuring the normal operation of the equipment and extending the service life of the equipment. The pulp level detection device 6 also communicates with the control panel The filter box 3 is connected to the filter plate 32 to monitor the slurry surface height in real time. A pushing device 4 is provided in the slot 34 below the filter plate 32. The pushing device 4 abuts against the filter plate 32. The width of the slot 34 is greater than the filter plate 32, which is convenient for the pushing device 4 to push the filter plate 32 to vibrate, thereby preventing the filtered bean dregs slurry from blocking the filter plate 32, thereby increasing the service life of the filter plate 32 and ensuring the filtering efficiency. The cover 33 fits the outer surface of the filter box 3 perfectly. The filter plate 32 can be pulled out for replacement by simply removing the cover 33. Inspection doors are detachably installed on both sides of the box body 31 close to the cover 33. The inspection doors are detachably installed on the box body 31 by bolts, which is convenient for maintenance or replacement of the pushing device 4.

[0031] The pushing device 4 includes a cylinder 41, a lower shock absorbing block 42 and an upper shock absorbing block 43. The cylinder 41 is installed in the box body 31 below the slot 34. The telescopic end of the cylinder 41 abuts the filter plate 32. The lower shock absorbing block 42 is correspondingly installed on both sides of the telescopic end of the cylinder 41. The upper shock absorbing block 43 and the lower shock absorbing block 42 are relatively arranged. The filter plate 32 is located between the lower shock absorbing block 42 and the upper shock absorbing block 43. The filter plate 32 is quickly pushed upward by the pushing device 4, and further quickly retracted to make it fall quickly from a high point until it touches the lower shock absorbing block 42. The collision vibration effectively cleans the bean dregs or other impurities accumulated on the filter plate 32, ensuring that the filter plate 32 continues to maintain an efficient filtering capacity, while also reducing noise. The lower shock absorbing block 42 and the upper shock absorbing block 43 are preferably soft rubber blocks, which reduce the collision and wear of the filter plate 32 itself and the box body 31, thereby extending the service life of the filter plate 32. The cylinder 41 adopts

[0032] A plurality of grooves are provided at the end of the return slurry pipe 2, and a plurality of grooves are provided at the end of the return slurry pipe 2 at the slurry outlet part. The grooves can serve as gas escape channels, effectively avoiding the occurrence of breath holding, thereby ensuring the smooth flow of the slurry (soy milk) and increasing the return slurry efficiency. A driving motor 9 is provided on the outer surface of the slurry storage box 5, and a stirring shaft 7 is installed on the output shaft of the driving motor 9. The stirring shaft 7 fully mixes the water-injected slurry to achieve an adapted concentration.

[0033] The parts and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.

[0034] Working principle: The proportional valve 1 of the slurry inlet pipe and the water injection pipe is opened or closed through the control panel to complete the slurry inlet and water injection. The slurry first enters the filter box 3 for filtration and purification. When the slurry level at the slurry outlet of the filter box 3 reaches a certain height, the slurry level detection device 6 therein detects and feeds back the signal to the control panel, and the control panel closes the proportional valve 1 of the slurry inlet pipe. At this time, the sanitary pump 10 of the slurry return pipe 2 is started to perform secondary filtration and purification on the slurry in the slurry outlet. After the secondary filtration, it is transported to the slurry storage box 5 through the slurry outlet pipe. At this time, the proportional valve 1 of the water injection pipe is opened for water injection, and the mixing is carried out through the stirring shaft 7. The concentration is detected by the concentration detector 8 in the slurry storage box 5. If the numerical judgment value is less than the specified value, the controller transmits it to the proportional valve 1 on the slurry inlet pipe, and the proportional valve 1 is opened to transport the soy milk. The above steps are repeated until the concentration is suitable.
