According to incomplete statistics, the discharge of catering wastewater accounts for about 30% of the total urban domestic sewage discharge.

[0003] The oil separator lifting equipment is a device that uses the oil-containing wastewater under the action of gravity, with the help of the difference in specific gravity of oil and water, to separate and remove the floating oil and some finely dispersed oil in the wastewater by natural flotation, thereby separating the oil and water. The oil separator lifting equipment enables the wastewater to be discharged through the inlet and outlet or into the sewage lifting tank for discharge.

[0030] The programmable controller 1 is provided with a detachable memory card inside to facilitate data storage and movement. The memory card is preferably a TF card.

[0031] In order to better illustrate the control system of the oil separation lifting equipment of the present invention, the main operating principles of the oil separation lifting equipment are described below:

[0032] The oil separation and lifting equipment includes a lifting pump, a grille machine, an air flotation pump, a heating device and an oil scraper;

[0033] The lifting pump is used to lift the water after the oil separation treatment to the next treatment stage or directly discharge it;

[0034] The screen machine is used to remove solid impurities in sewage, such as food residues, paper, etc., to prevent these impurities from entering subsequent treatment equipment;

[0035] The flotation pump is used to generate bubbles during the oil separation process to help grease and solid particles float to the water surface for easy separation;

[0036] The heating device is used to maintain the fluidity of grease in a cold environment, prevent the grease from solidifying, and ensure the grease isolation effect.

[0037] The oil scraper is used to scrape together the grease floating on the water surface for collection and treatment.

[0038] Specifically, the controller parameters include liquid level value, temperature value, weight value and float water level, etc. The controller parameters can be adjusted according to different control requirements.

[0039] The analog quantity acquisition module 4 is used to collect data from the sensor transmitter so as to start the oil separation lifting device according to the data from the sensor transmitter;

[0040] The sensor transmitter includes a liquid level transmitter, a temperature transmitter and a weight transmitter.

[0041] It should be noted that the present invention starts the oil separation lifting device by comparing the controller parameters with the data of the sensor transmitter. When the data of the sensor transmitter reaches the controller parameters, the oil separation lifting device is started.

[0042] For example, the liquid level value is compared with the parameters of the liquid level transmitter, the temperature value is compared with the data of the temperature transmitter, and the weight value is compared with the data of the weight transmitter to determine whether the oil-water separation lifting equipment needs to be started. The specific judgment conditions are existing technologies and can be set according to actual conditions and are not limited here.

[0043] In terms of signal input, the input terminal group 5 includes a power input terminal, a current transformer input terminal and a switch input terminal;

[0044] The power input terminal is used to connect to the power supply, the current transformer input terminal is connected to the current transformer to receive the fault status signal of the oil separation lifting equipment, and the switch input terminal is used to connect to the feedback signal;

[0045] The input terminal group 5 further includes a signal input terminal, and the communication module 3 is connected to the signal input terminal via a shielded wire to perform remote monitoring via the RS485 communication protocol.

[0046] The fault state signal includes underload, overload and phase loss, that is, when the oil separation lifting equipment is in a state of underload, overload and phase loss, it is uniformly judged as a fault state;

[0047] The feedback signals displayed on the display 21 include the status feedback signal of the lifting pump, the status feedback signal of the screen machine, the feedback signal of the scraper and the float water level signal, so that the operator can understand the information of the lifting pump, the screen machine, the scraper and the float water level in real time.

[0048] When the current transformer input terminal does not receive the fault status signal but receives a start or stop signal, the output terminal group 6 outputs a control signal to the relay group 7 to control the oil separation lifting device. The start or stop signal is issued by the programmable controller 1 or the manual control module 22.

[0049] The display hand controller 2 further includes an indicator light 23 provided below the display 21;

[0050] The manual control module 22 includes a grille start button, an oil drain start button, a start button, a stop button, a manual / automatic / setting button, and a lock / main / standby button.

[0051] Preferably, in actual application, two sets of the oil separation lifting equipment can be used, wherein one set of the oil separation lifting equipment is in use while the other set of the oil separation lifting equipment is in standby state;

[0052] Correspondingly, there are two start buttons, including 1# start button and 2# start button, and two stop buttons, including 1# stop button and 2# stop button;

[0053] More preferably, the indicator lights 23 are provided with six, including a 1# operation indicator light, a 1# fault indicator light, a 1 in use and 2 standby indicator lights, a 2# operation indicator light, a 2# fault indicator light, and a 2 in use and 1 standby indicator light;

[0054] Select one of the oil-water separation lifting equipment as 1# equipment and the other as 2# equipment. Obviously, when 1# equipment is in use and 2# equipment is in standby state, the 1# operation indicator light and the 1 in use and 2 standby indicator lights will light up; they can be controlled by the buttons of the manual control module 22.

[0055] To sum up, the oil-water separation lifting equipment control system of the utility model organically integrates multiple functional controls into one system, and realizes the connection of various devices in the oil-water separation lifting equipment through a bus control circuit, thereby improving the flexibility of practical application, reducing the number of wiring, and facilitating management.

[0056] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
