Automatic filling, adding, dissolving and liquid supplying system for upright soft bag powder

Abstract

The invention discloses an automatic filling, adding, dissolving and liquid supplying system for upright soft bag powder. The automatic filling, adding, dissolving and liquid supplying system comprises a fixed support frame, a rotating frame, an annular chain plate type conveyor, a first powder bag pushing-out mechanism, a powder bag clamping mechanism, a lifting type water injection bag opening mechanism, a stirring barrel, a self-circulating pipe, a liquid storage barrel and a control box. According to the automatic filling, adding, dissolving and liquid supplying system, complete automationof the whole set of operation process of powder bag opening, filling liquid preparation and empty bag recycling is achieved, manual participation is needed only when powder bags are placed, the automation level of the system is greatly improved, the dependence on personnel is reduced, and the labor intensity of the personnel is reduced.

Description

Technical field [0001] The present invention relates to the technical field of hemodialysis, more particularly, to a standing pouch automatic powder dosing was dissolved perfusion liquid supply system. Background technique [0002] Currently, well-known medical hemodialysis concentrate liquid supply system is mainly divided into the central concentrate supply system and the central dialysate supply systems into two categories, mainly of used central concentrate supply system, in this system, the liquid supply apparatus concentration quantitative work under dosing, storing and outputting concentrate. [0003] Conventional automatic dosing device there are four, three domestic often used: the first using pouch cracks implemented method, as follows: powder bags manually placed on the feed conveyor, the bag opening means is motor-driven multi-row hob, the hob bag was cut into multiple segments, by rotation or vibration of the cartridge, separated from the bag body and powders, dusts ...

AI Technical Summary

Problems solved by technology

[0004] But above-mentioned four kinds of ways all have the following shortcoming: cracking bag body cooperates the realization scheme of filtering device, and major shortcoming is: easily cause the pollution of powder in the process of cracking bag body, and powder is easy to block filter screen, and the acidity and alkalinity of powder easily Corrosion of the cutter and filter, meanwhile, the powder is also polluted by the cutter and filter

The main disadvantages of the realization scheme of buffer powder discharge by weight are: the powder buffer box has very high requirements on temperature and humidity, and the discharge metering device has high precision requirements, resulting in very high equipment costs

The buffer box needs to be in contact with the external environment when feeding and discharging. During this period of time, the quality of the buffer box powder is difficult to control, and the equipment also has very high requirements for the environment in which it is used.

The main disadvantage of the implementation plan of hanging and walking cutting the bottom of the bag is that the distance between the powder bags on the suspension system is not fixed, and mutual impact will affect the positioning and equipment stability

The opening and closing of the clip is manually operated, not only when filling the bag, but also when recycling the empty bag, which is highly dependent on personnel

The cutter needs to be in direct contact with the powder bag when opening the bag, causing powder pollution

The receiving funnel below may not be able to completely collect the powder, it is inevitable that the powder will spill out and pollute the equipment, and the powder on the funnel will breed bacteria after sticking, requiring frequent cleaning

The method of cutting and opening the bag cannot guarantee that the bag body is completely opened, and there will be some material left in the bag, which not only affects the concentration of the liquid, but also pollutes the equipment during recycling

The main disadvantages of foreign solutions for clamping and perfusing the bag are: the shape of the bag is cubic, and there are only limit plates on both sides on the conveyor. Next, limit the number of cache bags

No clear design for empty bag recycling
