Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation. Background Art

[0002] The overall scale of the hot pot market is expanding rapidly. According to statistics, the number of hot pot restaurants has increased by about 30% in the past five years, and this trend is expected to continue in the next few years. The market size is estimated to be several billion yuan, and it is expected to maintain a strong growth momentum in the next few years. A large amount of sewage and wastewater will inevitably be generated in the operation. In order to protect the environment and maintain public health, measures should be taken to treat the sewage and wastewater left after customers use the remaining hot pot soup base so that it meets the relevant national emission standards. Then, how to treat the sewage and wastewater of hot pot restaurants to meet the emission standards has become an important part that cannot be ignored.

[0003] On the one hand, the soup base after consumption contains a lot of waste oil, which has great recycling value. Directly pouring it into the sewer wastes resources and causes pollution. On the other hand, the soup base of hot pot restaurants is currently sent to the kitchen manually, and the boiling oil and pot body are huge hidden dangers during the transportation process, which is low in labor efficiency and difficult to transport. Therefore, the oil-water separation and recycling machine for hot pot restaurants came into being.

[0004] At present, there are many oil-water separation devices suitable for the catering industry, such as the public document with announcement number CN 111847686A, publication date October 30, 2020, and patent name "An Oil-Water Separation and Recovery Equipment for the Catering Industry". The disclosed oil-water separation and recovery equipment for the catering industry includes an oil separator, a feed box, and a discharge tank. The oil separator is connected to the feed box and the discharge tank through pipelines, respectively. In terms of height, the feed box is higher than the oil separator, and the oil separator is higher than the discharge tank. The oil separator includes a tank body, a core tube, and a filter layer. The filter layer is arranged at the lower part of the tank body, and the filter layer divides the tank body into an oil-water chamber and a water inlet chamber. An oil discharge port is arranged on the upper side of the oil-water chamber, and an air vent is arranged on the top of the oil-water chamber. The core tube is inserted into the tank body from top to bottom, and the lower end of the core tube is located in the water inlet chamber. The top of the core tube is connected to a downpipe and a siphon tube respectively. The other end of the downpipe is connected to a feed box, and the other end of the siphon tube is connected to a discharge tank. The highest point of the siphon tube is lower than the bottom of the feed box and higher than the oil discharge port. The oil-water separation and recovery equipment also includes a piercing tube, one end of which is inserted into the tank body, and the other end is bent and connected to the highest point of the siphon tube. The highest point of the piercing tube is higher than the highest point of the siphon tube. Most of these products have the following disadvantages:

[0005] High labor intensity: Traditional hot pot restaurants require a lot of labor, especially in large-scale hot pot restaurants. The distance between the kitchen and the customer's dining area is far, and the pot body is heavy with waste oil and water, which will lead to an increase in labor costs and may also have a certain degree of impact on the health of workers.

[0006] Low efficiency: After using the hot pot, the hot pot pot needs to be taken back to the kitchen for cleaning. At the same time, the workers have to pour out the oil, clean the pot body and clean the table. During this period, they need to go back and forth. If multiple tables of guests finish their meals at the same time, a large amount of manpower will be required to clean up in order to meet the dining needs of guests during peak hours.

[0007] Safety accidents are prone to occur: since the table needs to be cleaned in time for the next table of guests to dine in time, the hot pot pot needs to be taken away in time before it cools down. In the process of being sent to the kitchen, and at night, due to the influence of light and the fatigue or distraction of workers, mistakes are easy to occur, resulting in water and oil splashing.

[0008] Hygiene and quality control: Manual operation may not be able to ensure high levels of hygiene standards and quality control, and is easily affected by human factors. During the handling process, water and oil spills on the ground and walls, which is difficult to clean.

[0009] High cost: Due to the large amount of manpower required, the labor cost is relatively high, especially in long-term operation, the cost will further accumulate. And due to factors such as the environment, it will cause certain harm to the human body, so the labor cost is generally high.

[0010] Not suitable for large-scale production: Currently, most of them are small-scale hot pot restaurants that recycle manually, which is inefficient and cannot meet large-scale market demand.

[0011] High eggshell damage rate: Manual separation of eggshells and egg liquid requires directly breaking the eggshells and pouring out the egg liquid. This is inefficient and can easily damage the eggshells, thus losing the aesthetic value of the eggshells as handicrafts. Summary of the invention

When the water level in the sewage tank reaches a set value, the water pump A is started. When the water level in the clean water tank reaches a set value while the water pump A is working, the water pump A is turned off. When the water levels in the clean water tank and the sewage tank reach the set value at the same time, an alarm is triggered.

[0016] An inductive water level sensor B is provided in the oil tank, and the inductive water level sensor B is connected to and outputs a water level signal to the PLC.

[0035] The following is a further detailed description of the specific implementation methods of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, the manufacturing process and operation method, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0036] The overall scale of the hot pot market is expanding rapidly. According to statistics, the number of hot pot restaurants has increased by about 30% in the past five years, and this trend is expected to continue in the next few years. The market size is estimated at tens of billions of RMB, and it is expected to maintain a strong growth momentum in the next few years. A large amount of sewage and wastewater will inevitably be generated in the operation. In order to protect the environment and maintain public health, customers should take measures to treat the sewage and wastewater after using the remaining hot pot base so that it meets the relevant national emission standards. So, how to treat the sewage and wastewater of hot pot restaurants to meet the emission standards has become an important part that cannot be ignored. On the one hand, the soup base after consumption contains a large amount of waste oil, which has great recycling value. Directly pouring it into the sewer and wasting resources also causes pollution. On the other hand, the soup base of the hot pot restaurant is currently delivered to the kitchen by hand. During the transportation process, there are huge hidden dangers for the boiling oil and the pot body, and the manpower efficiency is low and the transportation is difficult. Therefore, the oil-water separation and recycling integrated machine for hot pot restaurants came into being.

[0037] The integrated equipment for separating and recovering oil and water in catering industry is particularly suitable for separating oil and water in hot pot restaurants. As shown in the figure, it mainly includes solid screen 1, iron plate 2, hinge 3, cabinet door lock 4, universal wheel 5, button box 6, faucet 7, straight-through solenoid valve A8, straight-through solenoid valve B9, hose 10, latch lock 11, clean water tank 12, oil tank 13, oil outlet button 14, inductive water level sensor A15, aluminum profile 16, tripod 17, water purifier 18, sewage tank 19, water pump B20, inductive water level sensor B21, inductive water level sensor C22, infrared temperature sensor 23, aluminum plate 24, punching plate 25, heating block 26, water pump A27, oil pump 28, PLC 29, protection switch 30, guide rail 31, terminal block 32, lead-acid battery 33, power supply 34, thermostat 35, wiring terminal 36, touch screen 37, oil-water separation physical sedimentation device 38, and handle 39.

[0038] The whole device is a cuboid shell, and all devices are fixed inside the shell. There are 4 universal wheels 5 at the bottom of the shell, which can be pushed to the required position as needed for use. That is, the swill can be directly poured into the device for separation. The feeding port is located at the top of the device. Below the feeding port, it is indirectly connected to the physical sedimentation device 38 through the solid sieve 1. The solid sieve 1 is a metal mesh bag that can filter out most of the solid food residues. The solid sieve 1 is supported at the edge on the feeding port. In this way, every time the solid sieve 1 is almost full, it can be directly taken down for cleaning. It is convenient to use. The passage between the feeding port and the inlet of the physical sedimentation device 38 is a smooth one. The physical sedimentation device 38 adopts an existing oil-water separation device. The physical sedimentation device 38 is provided with an oil discharge port and a sewage discharge port. The oil discharge port is connected to an oil discharge pipe, and the sewage discharge port is connected to a sewage discharge pipe. The oil discharge pipe is connected to the fuel tank 13 through a direct-flow solenoid valve A8, and the sewage discharge pipe is connected to the sewage tank 19 through a direct-flow solenoid valve B9. The direct-flow solenoid valve A8 and the direct-flow solenoid valve B9 can control the two sewage discharge states. The whole device is preferably provided with a PLC 29 to control all devices. The PLC 29 is connected to and controls the operation of the physical sedimentation device 38. At the same time, the PLC 29 is connected to and outputs control signals to the direct-flow solenoid valve A8 and the direct-flow solenoid valve B9, and can directly control the opening of the direct-flow solenoid valve A8 and the direct-flow solenoid valve B9 after the physical sedimentation device 38 finishes processing, so as to convey the separated oil and water to the fuel tank 13 and the sewage tank 19 for separation.

[0039] A water pump A27 for sewage discharge is provided in the sewage tank 19. The water pump A27 is connected to the sewage inlet of the water purifier 18 through a hose 10. The clean water outlet of the water purifier 18 is connected to the clean water tank 12 through a hose 10. A water pump B20 is provided in the clean water tank 12. The water pump B20 is connected to a faucet 7 through a hose 10. The water purifier 18 is a water filter that can filter sewage into secondary purified water, and even reach the standard of purified water through multi-stage filtration. The water pump B20 is connected to the faucet 7 through a hose 10, and then the water can be directly used for flushing. For example, when used in a restaurant, the filtered purified water can be directly used to clean the floor, tabletop, etc. An oil pump 28 is provided in the fuel tank 13. The oil pump 28 is connected to an oil outlet through an oil pipe. The separated oil can be recycled and used in reasonable and compliant places.

[0040] Because the oil and water in the restaurant generally contain more animal oil, it is easy to freeze after separation, especially when the temperature is low, so a heating block 26 is fixed on the outer wall of the oil-water separation physical sedimentation device 38, and an infrared temperature sensor 23 is provided in the oil-water separation physical sedimentation device 38. The infrared temperature sensor 23 is connected and outputs a temperature signal to the thermostat 35, which can be used for constant temperature control. The thermostat 35 is connected and outputs a control signal to the heater. The thermostat 35 is fixed on the surface of the equipment. After manually adjusting the required temperature, the heating block 26 makes the temperature in the oil-water separation physical sedimentation device 38 constant at the set value when the equipment is working. In addition, the oil pipe passes through and contacts the heating block 26, which can ensure smooth oil discharge and avoid oil pipe blockage.

[0041] In order to facilitate the storage capacity exceeding the limit in the oil tank 13, the sewage tank 19 and the clean water tank 12, an inductive water level sensor A21 is provided in the sewage tank 19, an inductive water level sensor B22 is provided in the oil tank 13, and an inductive water level sensor C is provided in the clean water tank 12. The inductive water level sensor A21, the inductive water level sensor B22 and the inductive water level sensor C are all connected and output water level signals to PLC29. During specific operation, when the water level in the sewage tank 19 reaches the set value, the water pump A27 is started. When the water pump A27 is working and the water level in the clean water tank 12 reaches the set value, the water pump A27 is turned off. When the water levels of the clean water tank 12 and the sewage tank 19 reach the set value at the same time, an alarm is triggered. When the water level in the oil tank 13 reaches the set value, the straight-through solenoid valve A8 and the straight-through solenoid valve B9 are controlled to be closed.

[0042] In order to ensure the stability of the entire device, a lead-acid battery 33 is fixed at the bottom of the shell. The lead-acid battery 33 is connected to all electrical devices through a power supply 34. The lead-acid battery 33 has a large weight, low cost, and can meet the needs of repeated charging and use. PLC29 is set on an independent side, and aluminum for isolation is provided between the oil-water separation physical sedimentation device 38, the sewage tank 19, the oil tank 13, and the clean water tank 12 to provide temperature insulation to prevent high temperature from affecting PLC29.

[0043] The whole device is built with aluminum profile 16, fixed by foot frame 17, and the shell is covered by iron plate 2. The movement of the device is through the rotation of four universal wheels 5 under the device. A handle 39 is installed on the iron plate 2 near the solid sieve 1. The control of the whole device is provided by the control module. The control module has PLC 29, terminal 36, power supply 34, protection switch 30, thermostat 35, lead-acid battery 33, guide rail 31, terminal block 32, touch screen 37. These components are fixed by punching plate 25. The faucet 7 and the oil outlet are installed in the shell. The faucet 7 and the iron plate 2 next to the oil outlet are detachable parts. The control module and the oil and water tank in the device are isolated by aluminum plate 24, and the control module is locked with cabinet door lock 4 to ensure safety.

[0044] Before the machine is turned on, the corresponding program will first be imported into the main control PLC29. At this time, the b protection switch 30 is turned on, the machine starts, and the soup base in the hot pot used by the guests is manually poured into the solid screen 1. The solid residue is left in the solid screen 1 and starts to operate according to the set program. The oil-water mixture enters the oil-water separation physical sedimentation device 38 to separate the oil and water through physical separation. After reaching the specified liquid level, the oil flows into the oil tank 13 through the straight-through solenoid valve A8, and the sewage flows into the sewage tank 19 through the straight-through solenoid valve B9. When the sewage accumulates to the specified position in the sewage tank 19, the inductive water level sensor A21 on the sewage tank 19 senses it, and the inductive water level sensor A21 feeds back the electrical signal to PLC29. PLC29 transmits the signal to the water pump A27 in the sewage tank 19. The water pump A27 pumps water through the hose 10 through the water purifier 18 for deep purification. The purified water passes through the hose 1 0 enters the clean water tank 12, and the clean water tank 12 also has a water pump B20. When clean water is needed, the button box 6 on the iron plate 2 is pressed to start the water pump B20 to pump clean water into the hose 10, and the tap 7 on the iron plate 2 is manually opened to allow clean water to flow out for workers to use. The oil tank 13 also has an oil pump 28. Open the latch lock 11 and press the button in the device to pump oil from the oil pump 28 for recycling. The oil tank 13 also has an inductive water level sensor B22, and the clean water tank 12 also has an inductive water level sensor C. When the water level reaches the tank port, the sensor senses and transmits the signal to the upper PLC 29. The PLC 29 sends a signal to the direct-through solenoid valve A8 and the direct-through solenoid valve B9, and the solenoid valve is closed to prevent liquid overload leakage. A heating block 26 is installed under the oil-water separation physical sedimentation device 38 to prevent the oil in the oil-water separation physical sedimentation device 38 from solidifying and causing blockage. The heating block 26 transmits the temperature to the temperature controller 35 through the infrared temperature sensor 23, resulting in constant temperature heating.

[0045] This device uses machine physical sedimentation to separate waste oil and water, and through the interaction and cooperation between various devices, it guarantees the recycling of resources to a great extent and reduces the pollution to the environment. It adopts a multiple classification method and is controlled by program to liberate manual labor. Unlike traditional oil-water separators, this mechanism can move freely and has a recycling function, relying on program operation. Waste oil and water are separated inside it, on the one hand. Avoid the influence of external secondary pollution, on the other hand, it also prevents splashing of oil and water during the separation process, improves the stability, safety and high precision of the machine operation, and adopts 4 universal wheels 5 under the body. On the one hand, it ensures the stability of the machine operation, and at the same time greatly improves the efficiency of transmission and separation.

[0046] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
