[0021] The implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] according to Figure 1-4 As shown, the automatic liquid replenishing device of the sand core filter comprises a bottom plate 1;

A suction pump 13 is fixedly installed on the top of the support rod 2 14, and the suction pump 13 and the sand core filter 2 are installed through a rubber tube 2 8. When working, first fit the bottom of the bottom plate 1 to the flat ground, and after the device is placed stably, assemble the sand core filter 2 and place it between the infrared transmitter 3 and the infrared receiver 5, and then connect the liquid storage tank 10 and the sand core filter 2. After the devices are connected and installed together and debugged, they are started for operation. At this time, there is no reagent in the filter cup 203, and the infrared receiver 5 can receive the infrared signal of the infrared transmitter 3. The signal is fed back to the programmable analysis and control system 15, the diaphragm pump 7 is turned on, and the reagent in the liquid storage tank 10 is input into the sand core filter 2, and the suction pump 13 starts the suction filtration. When the infrared receiver 5 cannot receive the infrared signal of the infrared transmitter 3, the signal immediately feeds back the information to the programmable analysis and control system 15, and the liquid storage tank 10 stops supplying the reagent to the sand core filter 2. Then, when the suction filtration liquid in the sand core filter 2 reaches a certain position, the infrared receiver 5 cannot receive the infrared signal of the infrared transmitter 3, and immediately feeds back the information to the programmable analysis and control system 15, and the liquid storage tank 10 stops supplying the reagent to the sand core filter 2, and the suction pump 13 stops working, and the filtration is completed. At the same time, the sand core filter 2 can also manually control the opening and closing of the diaphragm pump 7 and the suction pump 13 to complete the suction filtration.

[0025] Furthermore, the sand core filter 2 is located between the infrared transmitter 3 and the infrared receiver 5, and corresponds to the infrared transmitter 3 and the infrared receiver 5; when working, the infrared transmitter 3 transmits infrared rays through the sand core filter 2 and is received by the infrared receiver 5.

[0029] Furthermore, the connecting assembly 4 includes a connecting rod 401 fixedly connected to the top of the filter cup 203, a threaded hole 404 that penetrates up and down is opened at the center of the connecting rod 401, an external threaded sleeve 403 is threadedly connected inside the threaded hole 404, a dust cover 204 is fixedly connected to the top of the external threaded sleeve 403, a socket 402 that penetrates up and down is opened on the right side of the center of the dust cover 204, the left end of the rubber tube 6 is inserted into the socket 402 and is rotatably connected to the socket 402 through a sealing bearing; when working, the threaded connection between the external threaded sleeve 403 and the threaded hole 404 facilitates the connection and installation of the dust cover 204 and the filter cup 203, and facilitates the disassembly of the dust cover 204, thereby facilitating the cleaning of the filter cup 203.

[0030] Furthermore, the infrared transmitter 3 and the infrared receiver 5 are respectively provided with three detection probes, namely probe A, probe B, probe C, probe D, probe E and probe F. The probe A and the probe D are used to detect the top liquid level of the filter cup 203, the probe B and the probe E are used to detect the bottom liquid level of the filter cup 203, and the probe C and the probe F are used to detect the top liquid level of the triangular flask 201; when working, it is convenient for the infrared receiver 5 to receive or not receive the infrared rays emitted by the infrared transmitter 3.

[0031] Working principle: When in use, first assemble the sand core filter 2 according to the test needs, and place it between the infrared transmitter 3 and the infrared receiver 5, then connect the liquid storage tank 10 and the dust cover 204 together, and start the operation after debugging the equipment. At this time, there is no reagent in the filter cup 203, and the probe E of the infrared receiver 5 can receive the infrared signal of the probe B of the infrared transmitter 3. The signal is fed back to the programmable analysis control system 15, and the diaphragm pump 7 is turned on. The reagent in the liquid storage tank 10 is input into the filter cup 203, and the suction pump 13 is turned on for suction. When the reagent in the filter cup 203 reaches a certain position, the probe E of the infrared receiver 5 When head D cannot receive the infrared signal of probe A of infrared transmitter 3, the signal will immediately feed back the information to programmable analysis and control system 15, and the liquid storage tank 10 will stop supplying reagent to filter cup 203. Then, when the filtered liquid in conical flask 201 reaches a certain position, probe F of infrared receiver 5 cannot receive the infrared signal of probe C of infrared transmitter 3, and the information will be immediately fed back to programmable analysis and control system 15. The liquid storage tank 10 will stop supplying reagent to filter cup 203, and the filtration pump 13 will stop working, and the filtration is completed. At the same time, the sand core filter 2 can also manually control the opening and closing of diaphragm pump 7 and filtration pump 13 to complete the filtration work.
