A sealed chemical reagent filling device with adjustable capacity

Abstract

This utility model relates to the technical field of chemical reagent filling equipment, and discloses an adjustable-capacity sealed chemical reagent filling device, which consists of a support assembly, an infusion assembly, a filling assembly, and an anti-drip assembly. Reagent is replenished to the storage tank through the inlet, and a water pump pressurizes and delivers the reagent to the infusion tube. Filling parameters are input at the control console, a first motor drives a rotating shaft to rotate, and a control valve adjusts the reagent flow rate in the infusion tube, controlling the filling capacity in conjunction with a time setting. A conveyor belt transports the reagent bottle to below the outlet tube, where a second motor drives a driving half-gear and a driven gear to rotate. A rotating rod opens the anti-drip plate, allowing the reagent to be filled into the reagent bottle through the outlet tube. After filling, the second motor reverses, and a torsion spring assists the anti-drip plate in closing and blocking the outlet tube to prevent leakage. The conveyor belt then transports the filled reagent bottle to the next process.

Description

Technical Field

[0001] This utility model relates to the technical field of chemical reagent filling equipment, specifically an adjustable-capacity sealed chemical reagent filling device. Background Technology

[0002] In the fields of chemical engineering, pharmaceuticals, and scientific research, the filling of chemical reagents is a critical step in the production and experimental process. Its "precision, sealing, and safety" directly affect the effectiveness of the reagents and the safety of the operators.

[0003] A search revealed existing technology (application number: CN202321296897.8), which describes "a chemical reagent and auxiliary agent filling device." This utility model incorporates a positioning mechanism to clamp and position the auxiliary agent packaging cans, enabling adaptive clamping and positioning based on different can models, thus improving the device's compatibility and practicality. A filling mechanism further automates the filling process, with a conveyor belt working in conjunction with the positioning and filling mechanisms to achieve automated transport and filling of the cans. This eliminates the need to replace any parts, simplifying the filling process and improving efficiency.

[0004] However, while existing technologies employ positioning mechanisms to clamp and position auxiliary agent packaging cans, enabling adaptive clamping and positioning based on different can models and improving compatibility and practicality, and filling mechanisms to automate the transportation and filling of these cans with the help of a conveyor belt, simplifying the filling process and increasing efficiency without requiring replacement of parts, some shortcomings remain. After filling, residual reagent in the outlet pipe of existing equipment tends to drip naturally, wasting reagent in each batch, especially for high-value reagents. The dripping reagent also contaminates the conveyor belt and the outer wall of the reagent bottles, requiring additional cleaning and affecting filling continuity. Furthermore, contaminated reagent bottles need to be re-sterilized, reducing production efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-capacity sealed chemical reagent filling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable-capacity sealed chemical reagent filling device, comprising: a support assembly, disposed on the ground; an infusion assembly, disposed inside the support assembly; a filling assembly, disposed on the support assembly; and an anti-drip assembly, disposed on the support assembly; wherein the filling assembly comprises: a control assembly, disposed on the filling assembly, for controlling the filling capacity.

[0007] As a further description of the above technical solution:

[0008] The canning assembly further includes: a housing, disposed on a support assembly; a control console, disposed on the housing; and an infusion tube, disposed inside the housing.

[0009] As a further description of the above technical solution:

[0010] The control assembly includes: a first motor, disposed inside the housing; a rotating shaft, one end of which is fixedly connected to the output end of the first motor, and the other end is rotatably connected to the housing, passing through and rotatably connected to the infusion tube; and a control valve, welded to the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The support assembly includes: a housing, set on the ground; hinges, evenly distributed, with one end set on the housing; two sets of doors, set on the other end of the hinges; a support frame, set on the ground; and a conveyor belt, set on the support frame.

[0013] As a further description of the above technical solution:

[0014] The infusion assembly includes: a storage tank, disposed inside the support assembly; an inlet, located on the storage tank; and a water pump, disposed on the storage tank.

[0015] As a further description of the above technical solution:

[0016] The anti-drip assembly includes: an outer casing, mounted on the canning assembly; a rotating rod, one end of which is rotatably connected to the canning assembly; an anti-drip plate, welded to the rotating rod; a driven gear, welded to the other end of the rotating rod; a second motor, located inside the outer casing; a driving half-gear, meshing with the driven gear and fixedly connected to the output end of the second motor; and a torsion spring, one end of which is welded to the canning assembly and the other end of which is welded to the rotating rod.

[0017] As a further description of the above technical solution:

[0018] The outer shell is equipped with a liquid outlet pipe for filling chemical reagents.

[0019] This utility model has the following beneficial effects:

[0020] The anti-drip component works in concert with a second motor, a driving half-gear, a driven gear, an anti-drip plate, and a torsion spring. After filling, the anti-drip plate quickly closes to block the dispensing pipe, improving the anti-drip rate. This reduces reagent waste per batch, saving reagent costs. At the same time, it prevents dripping from contaminating the conveyor belt and the outer wall of the reagent bottle, shortening cleaning time and reducing the frequency of re-sterilization of reagent bottles, thus improving filling continuity.
