Description

Technical Field

[0001] This application belongs to the technical field of injection pump liquid supply systems, and in particular relates to a liquid supply system that can synchronously supply liquid and replenish liquid with a single drive and two syringes. Background Art

[0002] The currently used injection pump quantitative liquid supply systems are all driven by a motor for a single piston or syringe, or a motor for multiple pistons or multiple syringes. The unidirectional liquid supply slurry realizes an uninterrupted and cyclic liquid supply mode through the alternating switching of two groups of motors driving multiple pistons or multiple syringes crosswise.

[0003] The above liquid supply modes are either only capable of supplying liquid through a one-way valve or require more driving mechanisms such as motors. The former cannot achieve an uninterrupted and cyclic liquid supply mode, and the latter has a higher cost. Utility Model Content

The liquid supply three-way mechanism is connected to the three-way solenoid valve A and the three-way solenoid valve B respectively through pipelines. The three-way solenoid valve A and the three-way solenoid valve B are respectively connected to different syringes of the two-syringe liquid supply and replenishment mechanism through pipelines. The three-way solenoid valve A and the three-way solenoid valve B are then connected to the liquid outlet three-way mechanism through pipelines. The liquid outlet three-way mechanism is connected to the nozzle three-way solenoid valve through a pipeline. The liquid storage bucket, the liquid outlet three-way mechanism, and the nozzle are located on the same pipeline, and a single drive and two syringes are used to realize a quantitative liquid supply method of synchronous liquid supply and replenishment; Tube A and / or syringe B can be composed of two syringes, three syringes, or multiple syringes.

[0007] Further, the two-syringe liquid supply and replenishment mechanism includes a frame, syringe A, syringe B, and a driving mechanism. The syringe barrel of syringe A is fixed on the outer side of the frame. The syringe barrel of syringe B is slidably arranged on the outer side of the frame. The piston handle of syringe B is fixed on the frame. The driving mechanism is located inside the frame. A connecting block is provided at the movable end of the driving mechanism. The connecting block is respectively connected to the piston handle of syringe A and the tail end of the syringe barrel of syringe B. The driving mechanism drives the piston handle of syringe A and the tail end of the syringe barrel of syringe B to move up and down, and thus the functions of liquid replenishment and liquid outlet can be realized within the same driving time.

[0008] Further, the driving mechanism can be a cylinder, a hydraulic cylinder, or other linear driving mechanisms.

[0009] Further, the driving mechanism is composed of a motor and a lead screw module driven by the motor. The lead screw module slider is respectively connected to the piston handle of syringe A and the tail end of the syringe barrel of syringe B. The linear driving accuracy of the lead screw module is the highest, and the liquid can be quantitatively proportioned.

[0011] Further, syringe A and syringe B are arranged on opposite side surfaces of the frame, and syringe A and syringe B are arranged vertically offset.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. The product of the present utility model is a two-way mechanism driven reciprocally by one motor, which outputs materials on one side and supplies materials on the other side. The supply and liquid supply are carried out simultaneously, maintaining the freshness of the slurry in the injection syringe and realizing continuous grouting at the same time.

[0014] 2. Cleaning and maintenance can also be completed in a cycle between the syringe and the liquid storage barrel, improving the degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS
