Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, and in particular to a waste liquid treatment device of a cleaning machine. Background Art

[0002] Sealed solvent cleaning machines are widely used in the field of industrial cleaning. They use a closed cleaning chamber and a solvent circulation system. The solvent is evenly sprayed on the surface of the object to be cleaned through a spray device. After dissolving the dirt, the solvent passes through a filter device to remove impurities and achieve recycling. However, during the cleaning process, a certain amount of waste liquid will be generated. If these waste liquids are discharged directly, it will not only waste resources, but also may pollute the environment. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a waste liquid treatment device for a cleaning machine, which has the advantages of solving the problems raised in the above background technology, improving resource utilization and reducing environmental pollution.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: The top of the waste liquid tank is provided with a mounting hole, the mounting hole is provided with a stirring assembly, the bottom of the waste liquid tank is provided with a condensing box, and a water storage tank is placed in the condensing box. A demisting pipe is provided between the bottom of the waste liquid tank and the evaporating box, and a defogger is provided on the demisting pipe.

[0005] By adopting the above technical scheme, when in use, the waste liquid in the cleaning machine is pumped into the feed pipe, and enters the filter box in the inner cavity of the waste liquid tank through the feed pipe. The waste liquid is further filtered and processed by the filter component in the filter box to filter out floating objects and large particles in the waste liquid. The filtered waste liquid enters the evaporation box through the drainage pipe at the bottom of the filter box. At this time, the operator connects the external power supply and provides heat by connecting the heating plate wire. When the heating plate is heated to a certain temperature, the waste liquid forms steam. During this process, the operator turns on the stirring component to stir the waste liquid, thereby improving the evaporation efficiency. At this time, the steam is separated from the concentrated liquid through the cooperation of the demister and the demister pipe. At this time, the steam enters the condensation box and releases heat by contacting with the condensed water in the water storage tank in the condensation box. This part of the condensed water can be reused or meet the emission standards after treatment. The condensation process ensures that the water in the steam is recovered in liquid form for subsequent treatment.

[0006] It is further configured that the filter assembly includes a filter mesh layer arranged in a filter box, and an activated carbon plate is also arranged at the bottom of the filter box.

[0007] By adopting the above technical solution, when the waste liquid enters the filter box through the feed pipe, it can filter out floating objects and large particles in the waste liquid through contact with the filter mesh layer. After the filtered waste liquid passes through the activated carbon plate, it can absorb odor or some organic pollutants in the waste liquid.

[0008] It is further configured that: a plurality of placement grooves are provided on the inner wall of the drainage tube, and activated carbon bags are placed in each of the plurality of placement grooves.

[0009] By adopting the above technical solution, the waste liquid passing through the drainage pipe can absorb odor or organic pollutants in the waste water by contacting with the activated carbon bag placed in the tank.

[0010] It is further configured that the stirring assembly includes a stirring motor arranged in the mounting hole, a stirring shaft is connected to the bottom of the stirring motor, the stirring shaft extends into the evaporation box, and a plurality of stirring plates are fixedly connected to the outer side of the stirring shaft.

[0011] By adopting the above technical solution, during the evaporation operation, the operator turns on the stirring motor to drive the stirring shaft and multiple stirring plates on the stirring shaft to rotate at a uniform speed, thereby cooperating with the heating component to accelerate the evaporation efficiency.

[0012] It is further configured that: a plurality of drainage holes are formed through the stirring plate, and a screen is provided in each of the plurality of drainage holes.

[0013] By adopting the above technical solution, during the rotating stirring process of the stirring plate, the plurality of drainage holes provided on the stirring plate can reduce resistance and improve stirring efficiency.

[0014] It is further configured that heat conducting plates are arranged around the bottom of the inner wall of the evaporator box, and the bottoms of the heat conducting plates are in contact with the heating plate.

[0015] By adopting the above technical solution, during the heating process, the heating plate increases the contact with the waste liquid by setting up multiple heat conducting plates, thereby improving the evaporation efficiency.

[0016] In summary, the present invention has the following beneficial effects: When the present invention is in use, the waste liquid in the cleaning machine is pumped into the feed pipe, and enters the filter box in the inner cavity of the waste liquid tank body through the feed pipe, and the waste liquid is further filtered and processed by the filter component in the filter box to filter out floating objects and large particles of debris in the waste liquid, and the filtered waste liquid enters the evaporation box through the drainage pipe at the bottom of the filter box. At this time, the operator connects an external power supply and provides heat by connecting to the heating plate wire. When the heating plate is heated to a certain temperature, the waste liquid forms steam. During this process, the operator turns on the stirring component to stir the waste liquid, thereby improving the evaporation efficiency. At this time, the steam is separated from the concentrated liquid through the cooperation of the demister and the demister pipe. At this time, the steam enters the condensation box and releases heat by contacting with the condensed water in the water storage tank in the condensation box. This part of the condensed water can be reused or meet the emission standards after treatment. The condensation process ensures that the water in the steam is recovered in liquid form, which is convenient for subsequent treatment. BRIEF DESCRIPTION OF THE DRAWINGS
