Description

Technical Field

[0001] The utility model specifically relates to a cleaning machine with a double-path discharge cooling function, belonging to the technical field of cleaning machines. Background Art

[0002] The automatic laboratory cleaning machine is one of the core equipment of modern laboratories. It replaces the traditional manual cleaning process with automation technology, significantly improving the efficiency and safety of experiments. It is suitable for many fields such as biomedicine, environmental monitoring, and food safety. During the operation of the cleaning machine, it needs to be drained many times. Currently, all laboratory cleaning machines on the market have single-channel drainage, which cannot meet the application of certain scenarios. The details are as follows:

[0003] 1. The washing machine drains water many times during operation, and the pollution degree of each drainage is inconsistent. For example, the main washing water usually contains acidic or alkaline cleaning agents, and there are also residual pollutants from the utensils themselves. The pollution degree is high and needs to be recycled separately; drainage with low pollution degree can be directly discharged into the municipal pipeline;

[0004] 2. In some application scenarios, such as the electronic semiconductor industry, the main wash reagent needs to be reused. After the main wash of the cleaning machine is completed, the cleaning machine needs to recycle the main wash water and then transport the water to the cleaning machine through a water pump for recycling when it is used next time. The rinsing water used in other cleaning steps does not need to be recycled;

[0005] 3. Depending on the residue, the cleaning method of the cleaning machine will use high-temperature cleaning. For example, the cleaning water may be heated to 80 to 93°C, and there are requirements for the discharge temperature of the discharge water, which needs to be lower than 60°C to avoid affecting the municipal pipeline. Utility Model Content

[0006] In order to solve the above problems, the utility model proposes a cleaning machine with dual-path discharge and cooling function. The cleaning machine has dual-path discharge, and the discharge has a cooling function, so that the cleaning machine can meet the application of various scenarios.

[0007] The cleaning machine with dual-path discharge and cooling function of the utility model comprises a cleaning machine body and a controller for controlling the operation of the whole machine, and also comprises:

[0008] A main discharge line, the input end of which is connected to the drain valve of the cleaning machine; a temperature transmitter is installed at the input end of the main discharge line;

[0009] A cooling water pipeline, wherein the cooling water pipeline comprises a first tee connected in series to the main discharge pipeline; a third end of the first tee is connected to the cooling water supply network through a first electric control valve;

When the drainage instruction is triggered during the operation of the cleaning machine, the discharged water enters the main discharge pipeline, and the drainage temperature is monitored by the temperature transmitter; when the temperature reaches the set value (for example, when the water temperature exceeds 60°C), the first electric control valve is opened, and the cooling water enters the main discharge pipeline through the cooling water supply network and the cooling water pipeline, and the discharged water of the cleaning machine is cooled and neutralized. When the water temperature is lower than 60°C, the first electric control valve is not opened, and the discharged water reaches the second three-way valve. The controller selects to open the second electric control valve or the third electric control valve according to the current cleaning mode; thereby the discharged water is sent to the second three-way valve. Enter the main wash water storage tank or temporary storage tank; the main wash water storage tank receives the main wash water, and when the main wash water is the washing water with a high degree of pollution, it can be centrally treated; when the main wash water is the main wash reagent, the main wash reagent can be centrally collected and reused. After the main wash of the cleaning machine is completed, the cleaning machine stores the main wash water in the main wash water storage tank, and when it is used next time, the water is transported to the main wash water supply port of the cleaning pipeline of the cleaning machine through a water pump for recycling; the temporary storage tank receives the rinse water, and uses the temporary storage tank to cool and neutralize the rinse water, saving the water supply of the cooling water pipeline, and then discharges the rinse water to the municipal pipe network through the overflow end of the temporary storage tank;

[0014] In addition, depending on the type of residue, the cleaning machine's cleaning method will perform high-temperature cleaning. For example, the cleaning water needs to be heated to 80 to 93°C. When the discharge temperature of the discharge water needs to be lower than 60°C, cooling water is connected through the cooling water pipeline to cool the discharge water, protect municipal pipelines, and extend their service life.

[0015] Furthermore, the main discharge line is provided with a one-way valve at the first three-way input end, and the one-way valve can prevent sewage from flowing back and polluting the clean main discharge line.

[0017] Furthermore, the cooling water supply network is a tap water network or a return water network of a temporary storage tank; cold water for neutralization of cold and heat is provided through the tap water network or the return water network.

[0018] Furthermore, it also includes a heat exchanger, the working medium flow channel of the heat exchanger is connected in series to the main discharge line; the cleaning pipeline of the cleaning body is connected to the heat exchange flow channel of the heat exchanger; the heat in the discharge water is recovered by the heat exchanger, thereby reducing the heat of the discharge water, and at the same time the heat is recovered and applied to the cleaning water in the cleaning pipeline for heating.

[0019] Furthermore, the main discharge pipeline, cooling water pipeline and main wash water discharge pipeline are composed of pipes with waterproof coating on the inner wall; if the waterproof coating adopts polytetrafluoroethylene coating, it can resist corrosion from the discharge water; the rinse water discharge pipeline is composed of stainless steel pipes to reduce costs.
