[0039] Turbidity meter 5 is fixedly installed on the front side of cleaning tank 1, and its detection end is fixedly inserted into cleaning tank 1. Turbidity meter 5 is electrically connected to PLC controller 2 through wires. Turbidity meter 5 is used to detect water turbidity value and transmits the turbidity value to PLC controller 2 through the analog input module of PLC controller 2.

[0040] An ultrasonic level sensor 201 is installed inside the cleaning tank 1. A rectangular through hole is provided on the top right side of the cleaning tank 1. A T-shaped support 202 located inside the rectangular through hole is connected to the right side of the cleaning tank 1. The ultrasonic level sensor 201 is fixedly connected to the bottom left side of the T-shaped support 202. The ultrasonic level sensor 201 is used to detect the water level and transmit the water level value to the PLC controller 2 through the analog input module of the PLC controller 2.

[0041] The air supply agitation bubble generation component is fixedly installed on the rear side of the cleaning tank 1 and connected to its interior, and electrically connected to the PLC controller 2; the air supply agitation bubble generation component is used to supply air to the water in the cleaning tank 1 to generate water flow bubbles, clean the added food, and is controlled by the PLC controller 2 to stop the air supply when the turbidity value exceeds the preset value.

[0042] The water supply rinsing assembly is installed on the cleaning tank 1 and electrically connected to the PLC controller 2. The water supply rinsing assembly is activated by the PLC controller 2 when the water level is lower than the preset minimum value, so as to rinse the bottom inner wall of the cleaning tank 1 and supply water to its interior.

[0043] The sewage discharge assembly is fixed to the bottom left side of the cleaning tank 1 and electrically connected to the PLC controller 2. The sewage discharge assembly is controlled by the PLC controller 2 to start the drainage work when the turbidity value exceeds the preset value, and is controlled by the PLC controller 2 to continue to operate for one minute when the water level value is lower than the preset minimum value.

[0044] In this embodiment, bearings are fixedly connected to the front and rear inner walls of the cleaning tank 1 and the front side of the rear support plate 102.

[0045] Furthermore, the T-shaped support 202 is welded to the right side of the cleaning tank 1.

[0046] Furthermore, such as Figure 2 and 3 As shown, the air-pumped bubble-generating assembly includes an air pump 3, an inclined tube 301, and multiple jet nozzles 302. The air pump 3 is fixedly installed on the rear side of the cleaning box 1. The inclined tube 301 is connected to and fixedly installed at the air outlet of the air pump 3. The left end of the inclined tube 301 is set as a sealing structure. The multiple jet nozzles 302 are all connected to and fixedly installed on the front side of the inclined tube 301. The front ends of the multiple jet nozzles 302 extend into the cleaning box 1 and are located above and behind the filter conveyor belt 104. The cleaning box 1 is fixedly fitted onto the outside of the jet nozzles 302 through the mounting holes opened on its rear side. The air pump 3 is electrically connected to the PLC controller 2.

[0047] In this embodiment, the air pump 3, the inclined tube 301, and multiple jet nozzles 302 work together to supply air into the inclined tube 301. The air is then blown forward into the cleaning tank 1 through the multiple jet nozzles 302 to agitate the water and generate water bubbles for cleaning the added food. The PLC controller 2 is used to preset the turbidity value that controls the air pump 3 and the geared motor 106 to shut down. When the water turbidity value exceeds the preset value, the PLC controller 2 controls the air pump 3 and the geared motor 106 to shut down to stop the air supply and conveying work.

[0048] Furthermore, such as Figure 1 and 2 As shown, the sewage discharge assembly includes a solenoid valve 4 and an L-shaped sewage discharge pipe 401. The solenoid valve 4 is fixed to the bottom left side of the cleaning tank 1, and the L-shaped sewage discharge pipe 401 is fixed to the bottom end of the solenoid valve 4. The solenoid valve 4 is electrically connected to the PLC controller 2.

[0049] In this implementation scheme, the solenoid valve 4 and the L-shaped drain pipe 401 work together. The PLC controller 2 is pre-set to control the turbidity value at which the solenoid valve 4 opens. It is also pre-set to control the solenoid valve 4 to continue opening for one minute after the water level reaches the minimum value before closing. When the turbidity value exceeds the preset value, the PLC controller 2 controls the solenoid valve 4 to open, so that the water in the cleaning tank 1 is discharged sequentially through the solenoid valve 4 and the L-shaped drain pipe 401. After the water in the cleaning tank 1 is discharged, when the water level is lower than the preset value, the PLC controller 2 controls the solenoid valve 4 to continue opening for one minute before closing.

[0050] Furthermore, such as Figure 1 and 2 As shown, the water supply and rinsing assembly includes a water pump 6, a one-way valve 601, a horizontal pipe 602, and multiple rinsing pipe heads 603. The water pump 6 is fixedly installed on the bottom right side of the cleaning tank 1. The one-way valve 601 is connected to and fixedly installed at the outlet of the water pump 6. The top of the one-way valve 601 is the outlet and is connected to and fixedly installed with a water pipe. The top end of the water pipe extends into the cleaning tank 1 and is connected to and fixedly installed at the bottom of the horizontal pipe 602. The bottom of the cleaning tank 1 has an installation through hole for fixing the water pipe. The front and rear ends of the horizontal pipe 602 are both set as sealing structures. Multiple rinsing pipe heads 603 are connected and fixedly installed at equal intervals on the left side of the horizontal pipe 602 and are inclined. The rinsing pipe heads 603 are adapted to the bottom inner wall of the cleaning tank 1. The water pump 6 is electrically connected to the PLC controller 2.

[0051] In this implementation scheme, the water pump 6, check valve 601, horizontal pipe 602, and multiple flushing nozzles 603 work together. The PLC controller 2 is pre-set to control the minimum water level at which the water pump 6 starts, and to pre-set the maximum water level at which the water pump 6 stops, the air pump 3 starts, and the geared motor 106 starts. The water inlet of the water pump 6 is pre-connected to an external water supply pipe. When the water level in the cleaning tank 1 is lower than the preset minimum value, the PLC controller 2 controls the water pump 6 to start. The water pump 6 draws external water and supplies it unidirectionally into the horizontal pipe 602 through the check valve 601. The water then flows out to the left through the multiple flushing nozzles 603, flushing the cleaning tank 1. The bottom inner wall of the cleaning tank is rinsed and cleaned to the left. The rinsing water is discharged through solenoid valve 4. After one minute, solenoid valve 4 closes and stops the drainage. The water supply to the cleaning tank 1 gradually increases. When the water level reaches the preset maximum water level, PLC controller 2 controls water pump 6 to turn off, air pump 3 to turn on, and geared motor 106 to turn on, stopping the water filling work and continuing the conveying and air supply for cleaning. Through automatic drainage, rinsing the bottom inner wall of the cleaning tank 1 for one minute after drainage, and automatically stopping water filling when the preset water level is reached, the automatic water replacement and cleaning effect is achieved, improving the convenience and automation of use.

[0052] It should be noted that the ultrasonic level sensor 201 is preferably a non-contact ultrasonic level sensor for water tanks and reservoirs, model SIN-ZP. The PLC controller 2 is preferably a Siemens S7-200SMART programmable controller with an integrated analog input module. This controller can receive the standard electrical signal transmitted by the ultrasonic level sensor 201 after detecting the water level value, and convert it into the actual water level value with the help of the integrated analog-to-digital conversion function. The turbidity meter 5 is preferably a TU510 online turbidity meter. This instrument has a dual-group analog signal output function and can provide two 0 / 4-20mA isolated analog signals. It can be directly connected to the analog input module of the PLC controller 2. When connecting, simply connect the signal output terminal of the turbidity meter to the corresponding terminal of the analog input module of the PLC controller 2 according to the positive and negative polarity correspondence, and then complete the relevant signal configuration and calibration in the PLC controller 2 to realize the transmission of turbidity value.

[0053] Regarding the connection between the one-way valve 601, water pump 6, and air pump 3 and the PLC controller 2, it is preferable to connect them directly via relays and wires to form an electrical connection controlled by the PLC controller 2. This wire-direct connection method is a conventional and mature known technology for controllers, and will not be described in detail here. In addition, by utilizing the time control function of this programmable controller, it can be programmed to control the solenoid valve 4 to continue opening for one minute when the water level is lower than the preset minimum water level, thereby realizing the time control function of the corresponding steps. The above operations are all conventional applications of programmable controllers, and will not be elaborated here.

[0054] Regarding power supply, considering that the bubble washing machine is used in food processing sites such as fruit processing plants, where power supply measures are sufficient and conditions are met, all electrical components of this device are connected to the local mains power supply. These components are connected to the power input interfaces of each device via conventional power distribution devices (not shown in the diagram), such as circuit breakers, contactors, and power modules, forming a complete power supply circuit. This power supply scheme is a conventional power distribution method for industrial equipment and is a mature and well-known technology, which will not be elaborated upon here.

[0055] This embodiment can perform food conveying and bubble cleaning. It can monitor water turbidity and automatically change the water when the turbidity value exceeds the preset value. It can also perform a one-minute rinsing of the bottom inner wall of the cleaning tank 1 before adding water after drainage, which further cleans the sediment at the bottom of the cleaning tank 1. Through automatic drainage, rinsing the bottom inner wall of the cleaning tank 1 for one minute after drainage, and automatically stopping water addition when the preset water level is reached, no personnel observation, judgment, or manual operation of water changing is required. It is simple to use, improves the convenience of use and the degree of automation of water changing, and saves labor costs.

[0056] The usage method of this embodiment is as follows: When using the bubble cleaning machine with water quality monitoring function, water is added to the cleaning tank 1 beforehand, and the air pump 3 and the reduction motor 106 are turned on. The reduction motor 106 drives the upper drive wheel 103 to rotate. The upper drive wheel 103 is used to cooperate with the lower drive wheel 103 to drive the filter conveyor belt 104 to rotate, and the poured food is conveyed to the upper right. The high-level receiving box is placed on the right side of the cleaning tank 1 to receive the food. When the air pump 3 is started, air is supplied into the inclined pipe 301. The gas is blown forward into the cleaning tank 1 through multiple jet nozzles 302 to supply air to the water and agitate it to generate water bubbles to clean the added food.

[0057] The PLC controller 2 is pre-set with preset turbidity values ​​to control the air pump 3 to shut down, the geared motor 106 to shut down, and the solenoid valve 4 to open. It is also pre-set to control the solenoid valve 4 to remain open for one minute after the water level reaches its minimum value before shutting it down. The minimum water level value for controlling the water pump 6 to open is also pre-set, as are the maximum water level values ​​for controlling the water pump 6 to shut down, the air pump 3 to open, and the geared motor 106 to open. The turbidity value is detected by the turbidity meter 5 and transmitted to the PLC controller 2 via its analog input module. The water level is detected by the ultrasonic level sensor 201. The water level value is transmitted to PLC controller 2 via the analog input module. During the cleaning process, when the water turbidity exceeds the preset value, PLC controller 2 controls the air pump 3 and the geared motor 106 to shut down, stopping the air supply and conveying operation. It also controls the solenoid valve 4 to open, allowing the water in cleaning tank 1 to be discharged sequentially through the solenoid valve 4 and the L-shaped drain pipe 401. The L-shaped drain pipe 401 is pre-connected to an external sewage pipe for wastewater discharge. After the water in cleaning tank 1 is discharged, if the water level falls below the preset value, PLC controller 2 controls the water pump 6 to start. The solenoid valve 4 is kept open for one minute before being closed. During this minute, the water pump 6 draws external water and supplies it into the horizontal pipe 602 through the one-way valve 601. The water then flows to the left through multiple flushing pipes 603 to clean the bottom inner wall of the cleaning tank 1. The flushing water is discharged through the solenoid valve 4. After one minute, the solenoid valve 4 closes to stop drainage. The water supply to the cleaning tank 1 gradually increases. When the water level reaches the preset maximum water level, the PLC controller 2 controls the water pump 6 to close, the air pump 3 to start, and the geared motor 106 to start. The system automatically stops adding water and continues the conveying and air-pumping cleaning process. It monitors turbidity and automatically changes water when the turbidity value exceeds the preset value. Before adding water after draining, it rinses the bottom inner wall of the cleaning tank 1 for one minute to further clean the sediment at the bottom of the cleaning tank 1. Through automatic drainage, rinsing the bottom inner wall of the cleaning tank 1 for one minute after drainage, and automatically stopping water addition when the preset water level is reached, no personnel observation, judgment, or manual water change is required. It is easy to use, improves the convenience of use and the degree of automation of water change, and saves labor costs.

[0058] Example 2

[0059] like Figure 5 As shown, this embodiment differs from Embodiment 1 in that: the T-shaped support 202 is detachably connected to the right side of the cleaning tank 1, the T-shaped support 202 is in movable contact with the top right side of the cleaning tank 1, the top right side of the cleaning tank 1 has two threaded grooves, and a knob bolt 203 is threaded into the threaded grooves. The right side of the T-shaped support 202 has two threaded holes that are threadedly connected to the corresponding knob bolt 203.

[0060] This embodiment facilitates the subsequent disassembly, removal, maintenance, and replacement of the ultrasonic level sensor 201, providing convenience for personnel in subsequent maintenance work of the ultrasonic level sensor 201.

[0061] The method of use in this embodiment is as follows: Unlike Embodiment 1, it also has the following functions: Utilizing the provided threaded groove, knob bolt 203, and threaded hole, the knob bolt 203 is threadedly engaged with the threaded groove to achieve threaded locking of the T-shaped support 202. Reverse rotation of the knob bolt 203 allows it to separate from the corresponding threaded groove, unlocking the T-shaped support 202. This allows the T-shaped support 202 to be moved to the right, causing the ultrasonic level sensor 201 to be removed. This facilitates the disassembly and removal of the ultrasonic level sensor 201, making it easier for personnel to disassemble and replace the ultrasonic level sensor 201 and providing convenience for subsequent maintenance work.

[0062] It should be noted that the T-shaped support 202 consists of a rectangular vertical plate and a rectangular horizontal plate integrally formed with the left side of the rectangular vertical plate. The right cross-sectional dimension of the rectangular vertical plate in the T-shaped support 202 is larger than the right cross-sectional dimension of the rectangular through hole. The rectangular vertical plate in the T-shaped support 202 can block the rectangular through hole on the right side. The rectangular horizontal plate in the T-shaped support 202 is used for mounting the ultrasonic liquid level sensor 201.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
