[0030] As Figures 1 to 4 shown, the application provides a kind of medicine storage tank, for storing various drug raw materials, intermediates, finished products etc., and can accurately show the liquid level height in medicine storage tank.The medicine storage tank includes tank body 1, sealing element 2, pressure sensor 3, liquid level signal transmitter 8, medicine inlet 10 and medicine outlet 11.Tank body 1 is generally cylindrical with cavity inside, for storing medicine 12.Pressure sensor 3 is installed at the bottom of tank body 1, for feeling the liquid pressure in tank body 1, sealing element 2 is installed on the side of pressure sensor 3 away from tank body 1, for forming sealing to pressure sensor 3, prevent medicine 12 from causing pressure sensor 3 to be corroded, cause pressure sensor 3 to be out of order, thereby reduce the service life of pressure sensor 3.Liquid level signal transmitter 8 is connected with pressure sensor 3 at one end, and is installed on the outside of tank body 1, for converting the pressure felt by pressure sensor 3 into liquid level height.Medicine inlet 10 and medicine outlet 11 are connected with tank body 1, for inputting medicine 12 and outputting medicine 12 respectively.
[0031] In some embodiments, one end of the pressure sensor 3 is connected with a connecting line 4, a cable 6 is arranged between the connecting line 4 and the liquid level signal transmitter 8, and the pressure sensor 3 transmits the pressure sensed in the tank 1 to the liquid level signal transmitter 8 through the connecting line 4 and the cable 6. The liquid level signal transmitter 8 calculates the liquid level height of the medicament 12 in the tank 1 through a pressure calculation formula and displays the liquid level height on the liquid level signal transmitter 8. The bottom of the tank 1 is provided with a passage 5 which is a circular or polygonal through hole for passing through the cable 6. The side of the tank 1 is provided with a bracket 7, and the liquid level signal transmitter 8 is installed on the bracket 7. The top of the tank 1 is provided with an observation hole 9 for facilitating the staff to observe the liquid level height of the medicament 12 in the tank 1.
[0032] Further, in some embodiments, the bottom of the tank 1 is provided with a first recess 101 in which the pressure sensor 3 is installed, and a second recess 102 is arranged at the outer periphery of the first recess 101 and connected with the sealing member 2. One side of the sealing member 2 is provided with a protrusion 201 which cooperates with the second recess 102 to fixedly connect the sealing member 2 with the tank 1, wrap the pressure sensor 3 in the first recess 101, and form a seal, which can not only prevent the medicament 12 from corroding the pressure sensor 3, causing the pressure sensor 3 to malfunction, and reducing the service life of the pressure sensor 3, but also prevent the medicament 12 from flowing out of the first recess 101 and the passage 5. The sealing member 2 is detachably connected with the tank 1, which facilitates the removal of the pressure sensor 3 for maintenance when the pressure sensor 3 malfunctions, and facilitates the maintenance of the pressure sensor 3.
[0033] Specifically, in the present embodiment, the first recess 101 is a rectangular recess, the second recess 102 is arranged at the outer periphery of the first recess 101, the depth of the second recess 102 is not less than 5 mm, and the protrusion 201 protrudes a length matching the depth of the second recess 102, so that the protrusion 201 and the second recess 102 are combined more tightly under the pressure of the medicament 12.
[0034] Specifically, in the present embodiment, the medicine inlet 10 is located at the top of the tank 1, which facilitates the input of the medicament 12. If the medicine inlet 10 is located at one side or the bottom of the tank 1, the medicament 12 in the tank 1 will form a certain pressure at the medicine inlet 10 when the medicament 12 is input, which is not conducive to the input of the medicament 12. The medicine outlet 11 is close to the bottom of the tank 1, and a metering pump can be additionally arranged between the medicine outlet 11 and the tank 1, and the liquid medicine is drawn out from the medicine outlet 11 through the metering pump.
[0035] Optionally, the sealing member 2 is a flexible silica gel sealing gasket which can well fit on the pressure sensor 3 after being subjected to the pressure of the medicament 12, and will not cause the pressure sensor 3 to lose the sensitivity of pressure transmission, so that the change of the liquid level in the tank 1 can be more accurately transmitted to the liquid level signal transmitter 8.
[0036] Optionally, the distance between the bracket 7 and the bottom of the tank 1 is set at 1.5m-2.0m, which is convenient for on-site personnel to observe and read the liquid level, and the liquid level signal transmitter 8 can also transmit information to the control room through wired or wireless mode.
[0037] Optionally, the material of the tank 1 is PE or glass fiber reinforced plastic, which is corrosion resistant and facilitates one-time molding of the first groove 101 and the channel 5 during processing.
[0038] The utility model working principle: medicament 12 from tank 1 top's medicine inlet 10 enters, discharges from tank 1 bottom's medicine outlet 11. During this period, the liquid level in the tank 1 changes, and the pressure sensor 3 arranged at the bottom of the tank 1 can sense the liquid level change in the tank 1. The pressure sensor 3 senses the pressure of the medicament 12 in the tank 1, and transmits the sensed pressure to the liquid level signal transmitter 8 through the connecting line 4 and the cable 6. The liquid level signal transmitter 8 calculates the liquid level height of the medicament 12 in the tank 1 through the pressure calculation formula, and displays it on the liquid level signal transmitter 8. The on-site personnel can read the liquid level height in the tank 1 by observing the reading on the liquid level signal transmitter 8. The sealing element 2 is connected with the second groove 102 on the tank 1 through the protrusion 201, forming a seal for the pressure sensor 3, preventing the medicament 12 from corroding the pressure sensor 3 and causing the pressure sensor 3 to malfunction. In addition, the sealing element 2 is detachably connected with the tank 1. When the pressure sensor 3 fails, it can be removed for maintenance. After maintenance, it can be put back in place, which is convenient for the maintenance personnel to maintain the equipment.
