Description

Technical Field

[0001] This utility model relates to the field of liquid level monitoring technology, specifically a low liquid level voice alarm device for a fruit granule bagging machine. Background Technology

[0002] In the production of fruit-flavored beverages and other food products, liquid level monitoring in the material tank of the fruit bag machine is crucial. It is typically equipped with a low-level voice alarm to alert workers to add material when the level is insufficient. However, because these materials often contain fruit particles and have a certain viscosity, they are prone to splashing and adhering to the level sensor's monitoring head during equipment operation.

[0003] Adhesive deposits can severely interfere with the normal detection of sensors: for ultrasonic sensors, they attenuate the sound signal; for photoelectric sensors, they form a misleading liquid film, ultimately leading to inaccurate level detection and causing false alarms or failure to alarm. Currently, the common cleaning methods to solve this problem are to remove the level sensor from the tank for manual cleaning, or to clean the sensor along with the entire tank after shutdown. These methods are not only cumbersome and inefficient, but also seriously affect the continuity and stability of production.

[0004] Therefore, it is necessary to propose a low liquid level voice alarm device for fruit granule bagging machines to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4As shown, a low liquid level voice alarm device for a fruit granule bagging machine includes a base plate 10. A water outlet pipe 1 and a fixed pipe 5 pass through the base plate 10. The fixed pipe 5 is fixedly connected to the base plate 10. A liquid level sensor 2 is fixedly connected to the top of the fixed pipe 5. A ring pipe 12 is fixedly connected to the outer side of the middle of the fixed pipe 5. The fixed pipe 5 communicates with the ring pipe 12 through multiple water outlet holes 11. A water inlet pipe 3 is connected to one side of the ring pipe 12. The water outlet pipe 1 is rotatably connected to the base plate 10. A sealing plate 6 is fixedly connected to the bottom of the water outlet pipe 1. A return water tank 14 communicating with the water outlet pipe 1 is opened at a position corresponding to the fixed pipe 5 on the sealing plate 6. The sealing plate 6 is driven to rotate by the water outlet pipe 1 to control the communication state between the fixed pipe 5 and the return water tank 14. Specifically, the liquid level sensor 2 is a photoelectric liquid level sensor or an ultrasonic liquid level sensor.

[0018] In use, the base plate 10 is fixed to the top of the tank 15. The liquid level inside the tank 15 is monitored by the level sensor 2. The water outlet pipe 1 is connected to the negative pressure pump. When material adheres to the probe of the level sensor 2, causing abnormal monitoring data, the sealing plate 6 is moved below the fixed pipe 5 by rotating the water outlet pipe 1, so that the fixed pipe 5 is connected to the return water tank 14. Then, clean water is sent into the ring pipe 12 through the water inlet pipe 3. The liquid is sprayed into the fixed pipe 5 through the water outlet hole 11 to rinse the probe of the level sensor 2. Finally, the negative pressure pump is started, and the fixed pipe 5 is discharged through the water outlet pipe 1, thereby preventing the rinsing water from entering the tank 15. After rinsing, the sealing plate 6 is reset by rotating the water outlet pipe 1 to prevent the sealing plate 6 from blocking the level sensor 2 from monitoring the liquid level.

[0019] Specifically, there are multiple water outlets 11, which are arranged in a circumferential array along the fixed pipe 5. The water outlets 11 are oriented towards the liquid level sensor 2 to improve the cleaning effect on the liquid level sensor 2.

[0020] In some embodiments, a limiting block 8 is fixedly connected to the outer side of the water outlet pipe 1, and an arc-shaped limiting groove 9 is formed on the base plate 10 at a position corresponding to the limiting block 8. Specifically, when the limiting block 8 is located at one end of the arc-shaped limiting groove 9, the fixing pipe 5 and the sealing plate 6 are staggered; when the limiting block 8 is located at the other end of the arc-shaped limiting groove 9, the fixing pipe 5 is connected to the return water tank 14. With the cooperation of the limiting block 8 and the arc-shaped limiting groove 9, the position of the sealing plate 6 can be easily determined, thereby making its use more convenient. Preferably, a handle 7 is fixedly connected to the outer side of the water outlet pipe 1 to rotate the water outlet pipe 1.

[0021] To prevent liquid leakage through the gap between the fixed pipe 5 and the sealing plate 6, a sealing ring 13 is embedded in the edge of the return water tank 14. The upper end surface of the sealing ring 13 is 1-1.5mm higher than the upper surface of the sealing plate 6, which ensures the sealing effect while avoiding excessive frictional resistance between the sealing ring 13 and the fixed pipe 5, which could cause the sealing ring 13 to fall off.

[0022] In some embodiments, an alarm is also included. The signal output terminal of the liquid level sensor 2 is electrically connected to the signal input terminal of the controller via an analog or digital signal line to continuously transmit the electrical signal of the current liquid level. Simultaneously, the control output terminal of the controller is electrically connected to the controlled terminal of the alarm. During operation, the controller collects and processes the signal from the liquid level sensor 2 in real time, comparing it with a preset threshold. Once the liquid level is detected to be outside the normal range (i.e., abnormal states such as being too high, too low, or fluctuating rapidly), the controller sends an electrical signal to the alarm through its output terminal, driving the alarm to activate and alert the operator. Specifically, the alarm is a voice alarm.

[0023] 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.
