Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste, and in particular to a kitchen waste anti-mixing washing device with a material blockage early warning function. Background Technology

[0002] An automated food waste treatment production line refers to a production line that uses automated equipment and technology to collect, sort, process, and recycle food waste. It aims to improve the efficiency of food waste treatment, reduce human intervention, and achieve the harmlessness, reduction, and resource recovery of food waste.

[0003] However, in automated food waste processing lines, the on-site air environment is often harsh, and the facilities are unattended. If there are issues like delayed material discharge or clogged filters, the lack of timely intervention can lead to equipment damage. This is especially true in the filtration and screening stages.

[0004] The prior art discloses an invention patent entitled: "An Integrated Equipment for Food Waste Treatment, Collection, Back-mixing Washing, and Conveying," with publication number CN112222143A. It includes a back-mixing washing device and a filtrate collection tank located at the liquid outlet of the back-mixing washing device. The bottom of the back-mixing washing device is equipped with a filter screen for solid-liquid separation, which transports the liquid from the back-mixing washing device to the filtrate collection tank.

[0005] However, when the filtrate collection tank in the patent application achieves solid-liquid separation, solid waste remains in the reverse mixing washing device. When sheet-like objects such as plastic film clog the filter screen, it will cause the accumulation of kitchen waste, affecting the separation efficiency of oil, water and residue, and in severe cases, it will cause damage to the equipment. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art where flaky residue remaining in the reverse mixing washing device causes filter screen blockage that cannot be detected in a timely manner.

[0007] To achieve the above objectives, this application proposes a kitchen waste anti-mixing washing device with a blockage warning function, comprising an anti-mixing washing device; a first support base and a second support base disposed at both ends of the anti-mixing washing device; a first weight sensor and a second weight sensor respectively disposed between the anti-mixing washing device and the first and second support bases; a flow meter disposed on the conveying pipe of the anti-mixing washing device; the first weight sensor, the second weight sensor, and the flow meter are all connected to a monitoring and analysis unit; a transmission unit is disposed between the first and second support bases, and the monitoring and analysis unit is connected to the transmission unit, triggering a blockage warning and tilt adjustment based on abnormal weight and flow data.

[0008] The kitchen waste anti-mixing washing device of this application with a blockage warning function has a flow meter on the conveying pipeline to monitor the flow rate of oil and water in the conveying pipeline; a first weight sensor and a second weight sensor are respectively installed at the connection between the first support base, the second support base and the anti-mixing washing device, and the above sensors, flow meter and monitoring and analysis unit are connected. When the filter screen is blocked, an alarm is triggered by the signal transmitted by the sensor and flow meter, which solves the problem in the prior art that the blockage of the filter screen caused by the flaky residue retained in the anti-mixing washing device cannot be detected in time.

[0009] As an improvement to the aforementioned cylinder, in order to enable the cylinder to change its tilt angle around the fixed pin as the axis, the reverse mixing washing device includes a cylinder and a rotating roller conveyor. The cylinder surrounds the end of the rotating roller conveyor, and the filter screen is set at the end of the rotating roller conveyor covered by the cylinder. The outer wall of the cylinder is hinged to the U-shaped support column of the first support seat through a connecting plate and a fixed pin.

[0010] Furthermore, in order to achieve dynamic monitoring by linking spring deformation with weight data, mounting slots are symmetrically arranged on both sides of the U-shaped support of the first support base. The first weight sensor is fixed to the bottom of the mounting slot, and a spring is set on its top. The top of the spring is connected to the end of the fixing pin.

[0011] Furthermore, in order to provide feedback on the load change of the rotating roller conveyor through the displacement of the ball bearings, an installation groove is provided on the limiting arc groove of the second support base. The second weight sensor is symmetrically arranged at the bottom of the installation groove, and a spring and a ball bearing are provided at its top. The rotating roller conveyor makes rolling contact with the ball bearings.

[0012] Furthermore, in order to adjust the tilt angle of the anti-mixing washing device by changing the height difference of the support seat through the extension and retraction of the cylinder, the transmission unit includes a bidirectional cylinder and a Y-shaped connecting rod. The two ends of the bidirectional cylinder are respectively connected to the first support seat and the second support seat through the Y-shaped connecting rod.

[0013] Furthermore, to ensure the stability of the support seat during the lifting process, both the first and second support seats include a hollow base. The base is slidably connected to the U-shaped support column and the limiting arc groove through a slide rail, and the slide rail is a T-shaped structure.

[0014] Furthermore, the two forks of the Y-shaped connecting rod are respectively connected to the slide rail on the outer wall of the base and the connecting plate of the U-shaped support / limiting arc groove. When the bidirectional cylinder extends, the included angle of one side of the Y-shaped connecting rod increases to lift the U-shaped support, and the included angle of the other side decreases to lower the limiting arc groove, forming an inclined gradient of the anti-mixing water washing device.

[0015] The beneficial effects of this application are as follows:

[0016] 1. The kitchen waste anti-mixing washing device with blockage early warning function of this application has a flow meter on the conveying pipeline for monitoring the flow rate of oil and water in the conveying pipeline; a first weight sensor and a second weight sensor are respectively installed at the connection between the first support base, the second support base and the anti-mixing washing device, and the above sensors and the flow meter are connected to the monitoring and analysis unit. When the filter screen is blocked, an alarm is triggered by the signal transmitted by the sensor and the flow meter, which solves the problem in the prior art that the blockage of the filter screen caused by the flaky residue retained in the anti-mixing washing device cannot be detected in time.

[0017] 2. The kitchen waste anti-mixing washing device with blockage warning function of this application has a simple structure, few electronic components, and is easy to maintain.

[0018] 3. This application provides a transmission unit between the first support base and the second support base. When blockage occurs, the unidirectional movement of the transmission unit can increase the tilt angle of the anti-mixing washing device. On the one hand, this ensures that kitchen waste does not overflow from the anti-mixing washing device and cause pollution to other equipment. On the other hand, it increases the difference between the data collected by the first weight sensor and the second weight sensor, assisting the monitoring and analysis unit in confirming the blockage.

[0033] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0034] Example 1:

[0035] like Figures 1-3 This application illustrates a kitchen waste back-mixing washing device with a blockage warning function. In order to detect filter blockage problems in a timely manner and issue an early warning, this application installs the kitchen waste back-mixing washing device with a blockage warning function on the kitchen waste back-mixing washing equipment.

[0036] Specifically, the system monitors the flow rate changes of oil and water in the pipeline in real time through the flow meter 4 on the delivery pipeline 103. Simultaneously, a first weight sensor 2 and a second weight sensor 3 are installed at key locations where the first support 61 and the second support 62 connect to the reverse mixing water washing device 100, respectively. Data from these sensors and the flow meter are transmitted in real time to the monitoring and analysis unit 5 for comprehensive analysis. The flow meter 4, installed on the delivery pipeline 103, is used to monitor the oil and water flow rate through the pipeline in real time. The flow meter 4 calculates the flow rate by measuring the fluid velocity or the pressure change generated by the fluid on the sensor. When the filter screen is clogged, the oil and water flow rate decreases, and the flow meter 4 detects this change. The first weight sensor 2 and the second weight sensor 3 are installed on the first support 61 and the second support 62 at both ends of the reverse mixing water washing device 100, respectively. These sensors are used to monitor the weight changes at both ends of the device. When one side of the filter becomes clogged, the accumulated debris on that side increases the weight of that part of the device. The weight sensor can detect this change. The flow meter 4, the first weight sensor 2, and the second weight sensor 3 are all connected to the monitoring and analysis unit 5. The monitoring and analysis unit 5 receives data from these sensors and analyzes the data using algorithms to detect abnormal decreases in flow rate and abnormal increases in weight. When both conditions are detected simultaneously, the monitoring and analysis unit 5 triggers a blockage warning.

[0037] Furthermore, since the cylinder 102 does not need to rotate, while the rotating roller conveyor 103 needs to rotate to discharge the solids inside after solid-liquid separation, a structure with a U-shaped support column 611 and a connecting plate 605 is provided to support the cylinder 102. Simultaneously, ball bearings 622 and a limiting arc-shaped groove 621 are provided to support the rotating roller conveyor 103 while allowing it to rotate freely. The first support base 61 has mounting grooves 606 and springs 604 on both sides of the U-shaped support column 611, with a fixing pin 612 connected to the top of the spring 604. This structure achieves dynamic monitoring through the linkage of spring deformation and weight data. The second support base 62 has a mounting groove 606 on the limiting arc-shaped groove 621, with a spring 604 and ball bearings 622 at the bottom of the mounting groove 606. The rotating roller conveyor 102 rolls in contact with the ball bearings 622. This structure provides feedback on the load changes of the rotating roller conveyor 102 through the displacement of the ball bearings 622.

[0038] Specific work process:

[0039] Food waste enters the reverse mixing and washing device 100 for processing.

[0040] Flow meter 4 monitors the flow rate in the delivery pipeline 103 in real time.

[0041] Weight sensors 2 and 3 monitor weight changes at both ends of the reverse mixing washing device 100.

[0042] The monitoring and analysis unit 5 receives and analyzes the data from the flow meter 4 and the weight sensors (2 and 3).

[0043] When an abnormal decrease in flow rate and an abnormal increase in weight are detected, the monitoring and analysis unit 5 triggers a blockage warning.

[0044] Furthermore, when the filter screen becomes clogged with flaky residue, the flow rate of oil and water through the filter screen will significantly decrease. At this time, the flow meter 4 will detect this change and transmit a first-level warning signal to the monitoring and analysis unit 5. Simultaneously, due to the increased internal pressure of the back-mixing washing device 100 caused by the filter screen clogging, if the oil-water mixture is not discharged in time, the weight borne by the first support 61 and the second support 62 will increase accordingly when kitchen waste is added to the back-mixing washing device 100 for the second time. The first weight sensor 2 and the second weight sensor 3 will detect this weight change. When this weight change reaches the warning value, a second-level warning signal will be transmitted to the monitoring and analysis unit 5. Upon receiving these two warning signals, the monitoring and analysis unit 5 will immediately issue a warning and cut off the power to the back-mixing washing device 100, thereby effectively preventing the equipment from continuing to operate due to filter screen clogging and thus damaging the equipment.

[0045] Furthermore, since the anti-mixing water washing device 100 is tilted, two support seats and two weight sensors are set up to more accurately capture the different weight changes in the front and rear sections of the anti-mixing water washing device 100, thereby determining whether a blockage has occurred.

[0046] Furthermore, the analysis process of the operating data of the first weight sensor 2 and the second weight sensor 3 is as follows:

[0047] Step 1: Within one interval, using the data collected by the first weight sensor 2 and the second weight sensor 3 as a reference, this data represents the pressure exerted by the anti-mixing water washing device 100 on the first support 61 and the second support 62 respectively. If, in subsequent intervals, the data collected by the first weight sensor 2 and the second weight sensor 3 gradually increase by a factor of two compared to the data collected in the first interval, a secondary warning signal is transmitted to the monitoring and analysis unit 5.

[0048] Furthermore, within the interval after the anti-mixing water washing device 100 starts working, the monitoring and analysis unit 5 receives a first-level warning signal and a second-level warning signal respectively, then issues a warning and cuts off the power to the anti-mixing water washing device 100.

[0049] Example 2:

[0050] like Figures 1-3 This invention illustrates a kitchen waste anti-mixing washing device with a blockage warning function. In order to assist in confirming the blockage situation through tilt adjustment, this invention provides a transmission unit 7 between the first support 61 and the second support 62.

[0051] Working principle:

[0052] Transmission Unit 7: Transmission Unit 7 includes a bidirectional cylinder 71 and a Y-shaped connecting rod 72. When the monitoring and analysis unit 5 receives a blockage warning signal, it controls the bidirectional cylinder 71 to extend and retract, which drives the height difference between the first support seat 61 and the second support seat 62 to change through the Y-shaped connecting rod 72. This achieves the tilt angle adjustment of the anti-mixing water washing device 100. The tilt adjustment not only prevents kitchen waste from overflowing and causing pollution in the event of blockage, but also further assists the monitoring and analysis unit 5 in confirming the blockage by increasing the difference between the data collected by the first weight sensor 2 and the second weight sensor 3.
