Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment and relates to a cleaning device, in particular to a cleaning device for a chemical laboratory. Background Art

[0002] When conducting experiments involving heavy metal elements such as copper in chemical laboratories, copper-containing waste liquid will be generated. The traditional way to treat copper-containing waste liquid is to use neutralization precipitation to make copper ions form copper hydroxide precipitates, and then remove the precipitate through a solid-liquid separation device. The operation method is that the staff pours the copper-containing waste liquid into a reaction tank, then adds alkaline solution, and waits for it to react. When pouring the copper-containing waste liquid, residual waste liquid will be left on the inner wall of the container, resulting in incomplete waste liquid recovery. The container often needs to be cleaned repeatedly. However, when the container is scrubbed and the waste liquid is poured using cleaning tools, the copper-containing waste liquid is likely to adhere to the hands and endanger human health.

The flushing tank 2 is a cylinder with an opening on the top, and the bottom of the flushing tank 2 is retracted downward; the reaction cylinder 3 is detachably installed at the bottom of the flushing tank 2, and a feed port is provided on the top of the reaction cylinder 3. The feed port passes through the bottom of the flushing tank 2 and extends to the bottom of the inner wall of the flushing tank 2; the cleaning mechanism is arranged in the flushing tank 2, and is used for flushing the inner wall of the container, and sending the waste liquid generated by the flushing from the feed port into the reaction cylinder 3 for neutralization reaction with the alkali solution. Specifically, the cleaning mechanism includes a water pipe 4 and a nozzle 5. The water pipe 4 is arranged in the flushing tank 2. The liquid inlet end of the water pipe 4 passes through the inner wall of the flushing tank 2 and extends to the outside of the flushing tank 2 to be connected with a water supply device; the nozzle 5 is fixedly installed at the liquid outlet end of the water pipe 4; before flushing, the container is first sleeved on the outer periphery of the nozzle 5, and then the flushing liquid is pumped into the water pipe 4 through the water supply device, and sprayed from the nozzle 5 to flush the inner wall of the container, so that there is no need to manually scrub the inner wall of the container with the help of cleaning tools. At the same time, by rotating and moving the container, the nozzle 5 cleans the inside of the container in all directions, and the waste liquid generated after cleaning flows into the reaction cylinder 3 for neutralization reaction with the alkali solution, which can prevent the waste liquid from adhering to the hands of the operator and endangering human health; and the waste liquid and the alkali solution react synchronously during the cleaning process, which can shorten the reaction time and improve the cleaning efficiency. In the above, the water pipe 4 is an L-shaped pipe, and the liquid outlet end of the water pipe 4 faces the opening side close to the flushing pool 2, so that the container opens downward during the cleaning process, further preventing the waste liquid from adhering to the hands of the operator.

[0035] In the above-mentioned embodiment, the interior of the nozzle 5 is a hollow structure; a liquid inlet hole is provided at the bottom of the nozzle 5, and the liquid inlet hole is connected to the liquid outlet end of the water pipe 4; an annular boss is provided on the side of the inner wall of the nozzle 5 away from the liquid inlet hole, and a plurality of liquid outlet holes are provided on the inner wall of the annular boss along a ring shape; an opening and closing component is provided inside the annular boss, and a control end of the opening and closing component passes through an end of the nozzle 5 away from the liquid inlet hole and extends to the outside of the nozzle 5, so as to sleeve the container on the outer periphery of the nozzle 5, and squeeze the control end of the opening and closing component to open the liquid outlet hole of the nozzle 5, so as to realize automatic flushing of the inner wall of the container. Specifically, the opening and closing assembly includes a sealing plug 8, a contact shaft 6 and a reset spring 7.

The two ends of the reset spring 7 are respectively fixedly connected to the operating part and the opposite surface of the nozzle 5, and the reset spring 7 is sleeved on the contact shaft 6. During the cleaning process, the container squeezes the operating part, so that the contact shaft 6 drives the sealing plug 8 to slide downward and disengage from the annular boss, thereby connecting the liquid inlet hole and the liquid outlet hole of the nozzle 5, so that the cleaning liquid is sprayed from the liquid outlet hole to rinse the inner wall of the container. After the rinsing is completed, the container is picked up, and the sealing plug 8 is reset under the elastic restoring force of the reset spring 7 to close the liquid outlet hole, effectively controlling the displacement of the cleaning liquid and reducing resource waste.
