Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Figures 1-5 The diagram shown is a complete structural schematic of a laboratory instrument cleaning device with wastewater treatment function according to this utility model. Please refer to [link / reference]. Figures 1-5This embodiment of a laboratory instrument cleaning device with wastewater treatment function includes a cleaning tank 100, a coagulation tank 200, and a purification tank 400. The cleaning tank 100 has a disinfection washing pool 110 on its upper inner side, and a mesh basket frame 120 is fitted inside the disinfection washing pool 110. The upper side of the cleaning tank 100 has a lifting frame 130 for vertically raising and lowering the mesh basket frame 120. The coagulation tank 200 is located on one side of the cleaning tank 100, and its inner cavity is equipped with a stirring assembly 300. Wastewater from the disinfection washing pool 110 is introduced into the inner cavity of the coagulation tank 200 through a pipe pump for coagulation treatment. The purification tank 400 is located on one side of the coagulation tank 200. The purified water after sedimentation in the coagulation tank 200 is introduced into the inner cavity of the purification tank 400 through a pipe pump for filtration and purification.

[0032] The disinfection and washing tank 110 is equipped with an ultrasonic transducer 1101 and multiple ultraviolet lamps 1102 on its inner side. The cleaning box 100 also has a storage chamber 140 at the bottom inside. The storage chamber 140 is equipped with an ultrasonic generator corresponding to the ultrasonic transducer 1101. The front of the storage chamber 140 has a matching door panel 150. It is understandable that the storage room 140 can be used to store cleaning solutions, flocculants, and related tools. Furthermore, it should be noted that the lifting frame 130 can be equipped with an electric lifting rail, hydraulic system, or mechanical transmission, among other methods; there are no limitations. Specifically, in use, glass instruments are placed in the mesh basket 120. Then, the lifting frame 130 lowers the basket and instruments into the disinfection and washing pool 110, submerging the instruments. Ultrasonic and ultraviolet light are then used for deep cleaning and disinfection of the glass instruments. A secondary rinse or soaking can be performed using a water tap. After completion, the mesh basket 120 is raised, and the water in the glass instruments is drained. This method is characterized by thorough cleaning and simple, convenient operation, bringing convenience to laboratory work.

[0033] A suction pump 220, connected to the inner cavity of the disinfection and washing tank 110, is installed on one side of the upper part of the coagulation tank 200. A dosing port and a corresponding cap 230 are located on one side of the top of the coagulation tank 200, also connected to its inner cavity. A discharge valve 240 is located at the lowest point of the bottom of the coagulation tank 200. A storage trough 210 is also provided on the top side of the coagulation tank 200 near the disinfection and washing tank 110. This allows laboratory instruments to be cleaned to be placed in the storage trough 210, and then, when cleaning is needed, to be placed in the mesh basket 120, either uniformly or selectively, facilitating the cleaning operation. The mixing assembly 300 includes a stirring rod 310 horizontally rotatably mounted on the top inner side of the coagulation tank 200, a pulley 320 fixed to the upper end of the stirring rod 310, a pulley 330 horizontally rotatably mounted on the upper end of the coagulation tank 200 via a rotating shaft, a belt 340 matchingly connected to the pulleys 320 and 330, and a reducer 350 disposed at the upper end of the coagulation tank 200 for driving the pulley 330 to rotate axially. It can be understood that this cleaning device, by equipping a small wastewater coagulation chamber suitable for cleaning laboratory instruments, namely the coagulation tank 200, can professionally treat laboratory wastewater with relatively small volumes. In addition, when the sludge in the coagulation tank 200 has settled to a certain extent, the sludge and the lower layer water can be discharged directly by opening the discharge valve 240. The discharge valve 240 can be connected to the sewage treatment system through an external pipeline. For example, the sludge can be discharged to the sludge collection unit, and when a sufficient amount is accumulated, the sludge can be dewatered and pressed into cakes using a filter press. The sludge collection unit or sewage treatment system can be equipped in the laboratory, or the collected sludge can be transported to the treatment station for unified treatment at regular intervals, etc. There are no restrictions on this.

[0034] The top of the purification tank 400 is also equipped with a suction pump 420 for introducing the settled water from the coagulation tank 200 into the inner cavity of the purification tank 400. The top of the purification tank 400 is also equipped with a hollow water distribution plate 410, which is connected to the output end of the suction pump 420. Several spray holes 4101 are opened at the bottom of the water distribution plate 410. The water distribution plate 410 allows water to be sprayed more evenly onto the filter screen 510, thus ensuring the filtration efficiency of the filter screen 510. The filter assembly 500 includes a filter screen 510 located in the upper inner part of the purification tank 400, an activated carbon filter layer 520 located below the filter screen 510, and a manganese sand filter layer 530 located below the activated carbon filter layer 520. The filter screen 510, activated carbon filter layer 520, and manganese sand filter layer 530 are installed in a drawer-type pull-out configuration with respect to the inner side of the purification tank 400. It is understood that the filter screen 510 can filter and remove impurities from the water after coagulation and sedimentation, and the activated carbon filter layer 520 can further adsorb and purify the filtered water, removing small particles and odors. Subsequently, the manganese sand filter layer 530 adsorbs and purifies heavy metals such as iron ions in the water. Specifically, in this embodiment, the wastewater generated in the disinfection and washing tank 110 is introduced into the coagulation tank 200 by a pipeline pump for stirring, followed by flocculation, sedimentation, and preliminary purification, allowing floating matter, organic matter, and inorganic matter in the water to be removed. After solid-liquid separation and sedimentation, the clear water after coagulation and sedimentation is introduced into the purification tank 400 by a pipeline pump. Under the action of filter screen 510, impurities in the water are further screened out. Then, with the cooperation of activated carbon filter layer 520 and manganese sand filter layer 530, the small particles, odors and heavy metals in the water are further deeply adsorbed and purified. With the cooperation of both, it effectively prevents and alleviates the drawback of existing laboratory instrument cleaning wastewater that cannot be treated in real time. It can be carried out simultaneously with the cleaning work, which reduces the spread of pollution sources and improves the environmental protection of the device.

[0035] It should be noted that in this embodiment, the laboratory instrument cleaning device is only suitable for conventional laboratory wastewater treatment. Although it has good versatility, it is not universally applicable. The device can be modified or supplemented according to the actual situation.

[0036] It is understood that in other embodiments, a removable cover plate can also be provided on the top of the coagulation tank 200 and the purification tank 400. In this way, the cleaning device can be used directly as an experimental platform, and the cover plate can be removed when maintenance is required. There is no limitation on this.

[0037] Furthermore, the bottom of the purification chamber 400 is equipped with a second drain valve 430 connected to its internal cavity, and the front of the purification chamber 400 is also equipped with a maintenance door 440 corresponding to the filter assembly 500. It can be understood that by opening the maintenance door 440, the filter assembly 500 inside the chamber can be easily removed for cleaning or replacement. In addition, the second drain valve 430 can be connected to the sewer network, river, sewage treatment system, etc., depending on the actual situation.

[0038] Furthermore, a controller for the cleaning device is also provided on the front of the cleaning tank 100. It can be understood that the staff can operate and preset multiple operating units of the cleaning device through the controller.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
