Problems solved by technology

[0009] 1) The main disadvantages of the implementation scheme of cracking the bag body with the filter device are: in the process of cracking the bag body, it is easy to cause powder pollution, the powder is easy to block the filter screen, and the acidity and alkalinity of the powder is easy to corrode the cutter and filter screen. At the same time, the powder It is also contaminated by cutters and filters, requiring frequent cleaning and maintenance of equipment, and thorough disinfection of dialysate;
[0010] 2) The main disadvantages of the implementation scheme of weighing and discharging the cache powder are: the powder cache box has very high requirements on temperature and humidity, and the accuracy of the metering device for discharge is also very high, resulting in very high equipment costs; It needs to be in contact with the external environment, and the quality of the powder is difficult to control during this period, so the equipment has very high requirements for the use environment
[0011] 3) The main disadvantages of the implementation scheme of hanging and walking cutting the bottom of the bag are: 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 clips is manually operated, not only when bagging Manual participation, empty bag recycling also requires manual participation, which is highly dependent on personnel; when the cutter opens the bag, it needs to be in direct contact with the powder bag, causing powder pollution; the receiving funnel below may not be able to completely collect the powder, and it is inevitable that there will be powder If the powder is spilled out, the equipment will be polluted, and bacteria will grow after the powder sticks on the funnel, which needs to be cleaned frequently; the method of cutting and opening the bag cannot ensure 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 dosing solution, but also Contaminate equipment during recycling
[0012] 4) The main disadvantages of the bag clamping and cutting bag rotation dumping scheme are: there is no buffer device, and the dependence on personnel is high; the cutter cuts the soft bag seal, and the cutter may not cut completely; when it is turned over and dumped, Relying on the fixed shoulder limit to maintain the position of the bag body does not guarantee that the bag package will not fall into the liquid dispensing barrel together with the powder, and the lid of the liquid dispensing barrel is turned inward, and there is a risk of contact with the dialysate; because of the shoulder limit , the recycling of empty bags is difficult to control by only relying on its gravity to slide freely

Abstract

The invention discloses an automatic bag-opening, adding, dissolving and liquid-supplying system for bagged powder. The automatic bag-opening, adding, dissolving and liquid-supplying system comprisesa temporary storage part, a discharging part and a liquid preparing barrel, wherein the temporary storage part comprises a driving mechanism, a hanging mechanism and a plurality of positioning clamp mechanisms; the hanging mechanism is formed by connecting a plurality of chain plates end to end and is in an oval track shape; and the discharging part comprises a rotary motor mounting bracket, a rotary motor, a loading box, a sealing clamp mechanism, a centering mechanism, a cutting mechanism, a bag locking push rod and a bag discharging push rod mechanism. The whole set of operation process ofpowder bag temporary storage, bag opening, feeding and empty bag recycling is completely automatic. Only manual participation is needed during bagging, so that the automation level of equipment is improved, and the dependence on personnel is reduced; meanwhile, discharging is thorough, material scattering is avoided, a bag opening is completely cut open in the bag opening process, elasticity is achieved in the discharging process, a powder bag is kept extruded, and thorough discharging is achieved; and after the bag is opened, the bag is sealed by the sealing clamp mechanism all the time, andthe liquid preparation barrel can ascend to be butted with the discharging part to avoid scattering.

Description

technical field [0001] The invention relates to the technical field of centralized liquid supply systems, and more specifically relates to a liquid supply system for automatically unpacking and dissolving bagged powder. Background technique [0002] At present, the known centralized liquid supply system is mainly divided into two categories: central concentrated liquid supply system and central dialysate supply system. my country mainly adopts the method of central concentrated liquid supply system. , Storage and output of concentrates. One dialysis powder aqueous solution is weakly acidic, and the other dialysis powder aqueous solution is weakly alkaline. When the powder is exposed to the air, it is easy to absorb water, which not only affects the quality but also breeds microorganisms. Guarantee the quality of the liquid medicine. [0003] At present, there are mainly four types of automatic liquid dispensing systems at home and abroad: [0004] 1) The method of cracking...
