[0039] As shown in the accompanying drawings for Figures 1-7 The utility model provides a technical scheme:

[0040] A kind of liquid chemical raw material automatic filling device, including support frame 1, the support frame 1 is L-shaped plate structure, constitutes installation base, and storage tank body 2 is fixedly connected on the outer side of the support frame 1, filling adjusting mechanism 3 and barrier mechanism 4 are also installed on the support frame 1, the filling adjusting mechanism 3 includes the injection pipe 310 for being used to raw material filling flow guide being communicated in tank body 2 export end, and flow regulating dial 37 being installed at the top of support frame 1, the dial 37 changes fluid passage sectional area by rotation movement, realizes the continuous regulation of chemical liquid injection flow, cooperates with the design of multiple channels and can accurately control the matching parameter of different raw materials, significantly improves the measurement precision of mixing process.The barrier mechanism 4 uses hierarchical protection design, and its main part is the blocking frame 43 being installed at the bottom of support frame 1, the barrier mechanism 4 controls blocking frame 43 displacement, after filling operation is completed, blocking frame 43 is quickly attached to the export end of injection pipe 310 and forms physical plugging, effectively blocks the gravity drop phenomenon of residual liquid in injection pipe 310 pipeline.This double protection mechanism avoids both the pollution risk of corrosive raw material to production environment, and prevents the security risk caused by accidental leakage of toxic medium, ensures that filling process meets the requirement of chemical safety specification.

[0041] In a preferred embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the filling adjustment mechanism 3 further comprises a motor 31 mounted on the outer wall of the support frame 1, the output end of the motor 31 is connected with a lead screw 32, the outer wall of the lead screw 32 is threadedly connected with a threaded block 33, the end of the threaded block 33 away from the lead screw 32 is further provided with a standardized mounting interface, and a telescopic electric rod 34 is vertically fixed to the interface, and the output end of the telescopic electric rod 34 is connected with a rack 35.

[0042] In the above description, the servo motor 31 is used as the driving core of the execution element, and a screw transmission pair can be formed by the lead screw 32 and the threaded block 33. When the motor 31 drives the lead screw to rotate, the threaded block 33 generates a precise displacement in the axial direction, converts the rotary motion into a linear reciprocating motion, and drives the threaded block 33 to move horizontally. In use, the piston end of the telescopic electric rod 34 is connected with the rack 35 in a flange connection manner to form a rigid connection, so that the telescopic stroke of the telescopic electric rod 34 is coupled with the meshing displacement of the rack 35 to provide a precise displacement input for the downstream execution mechanism (such as a flow regulating valve), thereby meeting the three control requirements of speed, position and force for the chemical filling process.

[0043] In a preferred embodiment, as shown in Figure 1 and Figure 4 , the top end surface of the support frame 1 is further provided with a support seat 36, the bottom end of a rotating disc 37 is rotatably arranged at the top end of the support seat 36, and a gear ring 38 is fixedly connected to the outer wall of the rotating disc 37. The gear ring 38 is meshed with the rack 35 in use, so that the rotating disc 37 and the gear ring 38 can be driven to rotate synchronously under the driving force of the rack 35 in use. The rotating disc 37 is provided with an adjusting hole 39, and the top end surface of the rotating disc 37 is provided with a sealing plate 311 to prevent liquid chemical raw materials from leaking from the joint between the rotating disc 37 and the gear ring 38.

[0044] Specifically, the number of the adjusting holes 39 on the rotating disc 37 is four, and the diameters of the adjusting holes 39 increase in size in sequence. In this way, the position of each adjusting hole 39 of different sizes can be adjusted by rotating the rotating disc 37, so as to adjust the flow of the liquid chemical.

[0045] In a preferred embodiment, as shown in Figure 1 , Figure 2 , Figure 6 and Figure 7 , the blocking mechanism 4 further comprises a limiting sliding groove 41 opened at the bottom end of the support frame 1, a limiting sliding block 42 is slidably arranged in the limiting sliding groove 41, the top end of a blocking frame 43 is connected with the bottom end of the limiting sliding block 42, a guide sliding groove 44 is opened on the top end surface of the blocking frame 43, and a handle 45 is connected to one side of the outer wall of the blocking frame 43.

[0046] In the above description, after the injection is completed, the handle 45 can be pulled to move the blocking frame 43. At this time, the blocking frame 43 can be moved through the sliding setting of the limiting sliding block 42 on the inner wall of the limiting sliding groove 41. With the movement of the blocking frame 43, it can be slid to the position below the three injection pipes 310 through the guide sliding groove 44. In this way, the injection pipe 310 can be closed and blocked by the blocking frame 43, which can prevent the chemical liquid remaining on the inner wall of the injection pipe 310 from dropping and causing safety hazards.

[0047] Specifically, the number of limiting sliding grooves 41 and limiting sliding blocks 42 is two, and the limiting sliding grooves 41 and limiting sliding blocks 42 are symmetrically distributed, which can uniformly support the blocking frame 43 on both sides, thereby improving the stability of the blocking frame 43 during movement and support.

[0048] Specifically, the number of guide sliding grooves 44 is three, and each guide sliding groove 44 corresponds to the position of three injection pipes 310.

[0049] The implementation principle of the automatic liquid chemical raw material injection device in the embodiment is as follows:

[0050] When the injection of different chemical liquids in the tank body 2 needs to be adjusted, the motor 31 is first started, and the output end will drive the lead screw 32 to rotate forward and backward. With the rotation of the lead screw 32, the threaded block 33 can move left and right reciprocally. With the movement of the threaded block 33, the electric telescopic rod 34 and the rack 35 are moved. After the rack 35 is moved to the position of one of the rotating discs 37, the electric telescopic rod 34 is started, and the output end will drive the rack 35 to move forward until the rack 35 moves to contact the tooth ring 38. Then the motor 31 is started again, which can drive the rack 35 to move. At this time, the rack 35 can be engaged with the tooth ring 38, thereby driving the tooth ring 38 to rotate. At this time, the tooth ring 38 will drive the rotating disc 37 to rotate through the rotating setting between the support seat 36. Through the rotation of the rotating disc 37, the adjustment hole 39 opened at the top end surface is rotated. Then the adjustment hole 39 of the required size is rotated to the position directly below the injection pipe 310, so that the adjustment operation can be completed. In this way, the flow of chemical liquid into the injection pipe 310 per unit time can be adjusted according to the size of the adjustment hole 39, so as to ensure the proportional injection of different chemical liquids and improve the accuracy, thereby avoiding the waste of chemical liquid.

[0051] After the injection is completed, the handle 45 can be pulled to move the blocking frame 43, at this time the blocking frame 43 can be moved through the sliding setting of the limiting sliding block 42 on the inner wall of the limiting sliding groove 41, and with the movement of the blocking frame 43, the blocking frame 43 can be slid to the position below the three injection tubes 310 through the guide sliding groove 44, so that the injection tube 310 can be closed and blocked by the blocking frame 43, so that the residual chemical liquid on the inner wall of the injection tube 310 can be prevented from dropping to cause a safety hazard.

[0052] It should be noted that the motor 31 and the electric telescopic rod 34 are both prior art known to those skilled in the art, and the specific model and power supply mode can be selected according to specific needs, which will not be repeated here.

[0053] The above is only a preferred embodiment of the present application, and is not intended to limit the scope of protection of the present application.
