I. General requirements
1.1 Assist in cleaning inorganic residues (such as lead, mercury, cadmium, arsenic, etc.) and organic residues (such as industrial dyes, hormones, greases, etc.) in laboratory glassware or plastics by washing water spray and cleaning solution. Dust, etc., the sample can be dried after cleaning.
*1.2 The organic residue after cleaning is <0.1mg/L, and the residual metal ion is <0.02mg/L. A provincial authoritative experimental report or certification on the cleaning effect must be provided to ensure the accuracy of the trace analysis results.
1.3 Provide ISO9001, CE and other relevant international authority certification, and provide 8 or more product patents related to washing machines (non-design patents).
2, structural design
2.1 Double-layer detachable heat-insulating and sound-insulating enclosure. The inner cavity is made of 316L stainless steel. The outer casing is made of 304 stainless steel. The visible parts of the cabinet and door body must not have exposed screws and rivets to avoid rust in humid environment.
* 2.2 The horizontal design of the whole machine, the height of the equipment is 1.1 meters, the basic and the test bench are flush, and the upper part is convenient for placing light weight items.
*2.3 Two cleaning racks are placed in the cleaning compartment; the maximum cleaning height of the lower cleaning rack is 23cm, the maximum cleaning height of the upper layer is 18cm, and the maximum cleaning capacity is a single cleaning of 520 or 7cm diameter vessels of 2ml liquid bottles (volume bottles, cones) Bottles, etc.) 120.
*2.4 The original double-layer vacuum glass door can clearly see the internal cleaning situation, and at the same time effectively insulation and reduce energy consumption.
2.5 With two water inlets, tap water and pure water can be connected at the same time. You can choose which kind of water to enter through the control panel operation.
3. Control system
*3.1 Industrial PLC microcomputer control system is adopted, which is not controlled by ordinary circuit board and single chip microcomputer. Industrial PLC is a professional microcomputer. It has special standards and design for waterproof, anti-electricity and anti-magnetic. It can also directly upgrade the control software without changing the circuit and easy to
upgrade.
*3.2 The control system adopts 7-inch color LCD touch screen, full Chinese operation interface, and Chinese prompts for operation and alarm.
*3.3 The control system has 12 standard cleaning programs and 99 custom cleaning programs. The cleaning program can be set and adjusted for different vessels and requirements.
3.4 The control system adopts three levels of password settings, which facilitates the management and operation of different levels to set and manage parameters.
4, cleaning system
*4.1 The cleaning pump is a professional European imported circulating pump with a water output of 800L/min. The water output is large and the flushing force is large. The circulating pump blades are treated with high temperature resistance and can work normally under the temperature of disinfecting water (above 93 °C).
*4.2 The cleaning cabin adopts two parallel water supply systems, and the water supply structure with water supply on the side. The water supply structure at the top is not used. The two roads supply water at the same time, reducing the water pressure loss of the water supply. The upper and lower layers of the water are in the same strength; the water is connected to the side, no need to find the water inlet, the access is convenient, and the joint is not easy to be damaged.
*4.3 Both cleaning racks adopt side water connection, central water distribution structure. Central water distribution, cleaning rack will connect water into the middle and evenly distribute water to each spray column to ensure uniform water output from each spray column. The background is consistent.
*4.4 The spray column of the cleaning rack is distributed in parallel, and the scattering distribution around the center is not
used to ensure the uniform distance between each spray column. The cleaning amount is also increased, and the placement and estimation of the vessel are also facilitated.
*4.5 The cleaning rack has no tall central water pipe, which saves space and is convenient to place. The upper and lower layers of the cleaning rack can be interchanged to facilitate the arrangement of the vessels.
*4.6 The cleaning cabin has a built-in double-layer 360-degree rotating spray arm. The nozzle adopts a fan-shaped nozzle design, which sprays a fan-shaped water curtain, which has a large flushing force and no dead angle. The use of a simple orifice nozzle reduces the external spray dead angle.
*4.7 Cleaning adopts automatic heating system, the heating temperature is adjustable, the maximum temperature can reach 93 °C, and the disinfection level is reached.
*4.8 The cleaning solution and the neutralizing solution are automatically added by two peristaltic pumps, and the added dose can be set
5, drying system
*5.1 Injectable hot air drying, the filtered air is heated and directly connected to the spray pipeline. The air temperature is adjustable from room temperature to 120 °C. The hot air is also dried in addition to the drying vessel to prevent internal water accumulation.
5.2 Dry air passes through a high-efficiency filter with an efficiency of 99.99%, ensuring clean air into the cleaning chamber and avoiding secondary contamination of cleaning items.
*5.3 With the filter alarm function, it can automatically determine whether the filter needs to be replaced. When the filter expires or is accidentally damaged, an alarm will be given and a Chinese prompt will be given.
*5.4 Equipped with a dual steam condensing unit to prevent hot steam from escaping the laboratory to the experimental environment during operation.
5.5 Internal and external balance air pressure hole design, no internal humid air circulation is needed for drying, which effectively shortens the drying time.
6, security protection
*6.1 Safety door lock design, the door body can not be opened during the cleaning process to preventwater spray, burns, caused by misoperation; it has the function of emergency door opening, and the door can be quickly opened after power failure.
*6.2 The door lock adopts the upper two-point locking structure. The door frame is locked on the left and right sides of the door The single-point door lock seal in the middle connection is more reliable and prevents water and steam from overfl owing.
*6.3 Perfect protection function, with cleaning agent missing alarm, main washing pump over temperatureprotection function, heating anti-dry function, main washing pump idling protection function, water level sensing detection function, cleaning warehouse over temperature protection function, all with Chinese prompt And alarm
*6.4 With the program self-test function and the device self-cleaning function, the set program can be self-tested, and the device can be automatically cleaned after cleaning to reduce the residue.
