Description

Technical Field

[0045] like Figure 10 As shown in the figure, as a specific solution, the control cabinet 109 is electrically connected to the negative pressure fan 1052, heavy metal detector 107, total organic carbon analyzer 108, display screen 110, acid-base detector 114, vertical compression cylinder 115, lifting cylinder 116, gyroscope 117, liquid level sensor 123, first electrically controlled valve 128, electric push rod 130, second electrically controlled valve 131, and clamping cylinder 140. A Bluetooth module is installed inside the control cabinet 109 to achieve overall control.

[0046] like Figure 5As shown, as a specific solution, rubber sleeves 138 are fixedly sleeved on the four edges of the side door panel 103. The rubber sleeves 138 are located between the side door panel 103 and the inner wall of the box body 101 to provide a seal between the side door panel 103 and the box body 101 and to fill the gap when the side door panel 103 closes the box body 101.

[0047] Instructions for use: When the entire device is in use, the waste liquid can be introduced from the collecting funnel 111. When pouring, the second electrically controlled valve 131 is first in a closed state, and the waste liquid is in the collecting funnel 111. The first probe 112, the second probe 113 and the acid-base detector 114 are used to detect the waste liquid. In conjunction with the heavy metal detector 107 and the total organic carbon analyzer 108, the type of the poured waste liquid can be determined, and whether the waste liquid is an organic solution, a heavy metal salt solution or an acid or alkali solution. After the judgment, a signal is further provided to the single-chip microcomputer in the control cabinet 109 to open the second electrically controlled valve 131 and at the same time open a first electrically controlled valve 128 to allow the waste liquid to enter the designated collection liquid tank 121, thereby realizing the classified storage of the waste liquid.

[0048] After classified storage, the overall sealing is good and volatile gases are not easy to enter the outside. The first electrically controlled valve 128 is in a closed state, and the lifting cylinder 116 can provide pressure to clamp the end ring 132 and the fitting sleeve 136 to clamp the rubber sealing ring 133, thereby forming a first seal. The rubber cushion 134 is further clamped by the fitting sleeve 136 and the horn cover 129 to provide a second seal. At the same time, an activated carbon adsorption layer 135 is provided on the horn cover 129, and a baffle 137 is also provided to form a gap, which provides a flow channel for the overflow gas, which can be adsorbed by the activated carbon adsorption layer 135, further reducing the overflow of volatile gases into the box body 101, greatly reducing the overflow of volatile gases.

[0049] When the whole device is pushed, it can be moved on the ground through the universal wheel 102. When moving, the gyroscope 117 is used to judge whether the entire device is moving or stationary. When it is in the moving state, the gyroscope 117 provides a signal to the single-chip microcomputer in the control cabinet 109, which is controlled by the single-chip microcomputer to always keep the first electric-controlled valve 128 and the second electric-controlled valve 131 closed, and keep the classification work stopped. When dumping the collected waste liquid, the vertical clamping cylinder 115 and the lifting cylinder 116 shrink, and the pressure plate 143 stops pressing down on the collecting liquid box 121, so that the end ring 132 is separated from the fitting sleeve 136, and the connection is cancelled. The electric push rod 130 shrinks and disengages from the recessed hole, canceling the closure of the side door panel 103. By pulling the side door panel 103, the bottom plate 118 is separated from the box body 101, so that the collecting liquid box 121 leaves the box body 101, and the clamping cylinder 140 shrinks and stops clamping the collecting liquid box 121, completing the installation of the collecting liquid box 121. The collecting liquid box 121 can be moved down, and the drain valve 122 door is opened to discharge the waste liquid.

[0050] At the same time, when adding waste liquid, it can be connected to the user's mobile phone through the Bluetooth module and can be controlled by the mobile phone.

[0051] When storing after classification and moving the whole thing, start the negative pressure fan 1052, and suction can be carried out inside the box 101 through the air inlet pipe 106 to provide a negative pressure environment to prevent volatile gases from leaving the box 101 directly. The sucked gas can be filtered through the high-efficiency filter 1053, the adsorption cotton layer 1054, and the activated carbon filter 1055, thereby improving the protective effect.

[0052] Advantages: The entire waste liquid collection device 100 has been improved on the existing technology. It has the function of diverting, classifying and storing waste liquid. The diverting liquid inlet mechanism is used for the entry of waste liquid. By analyzing the waste liquid, the nature of the waste liquid can be judged, so that the waste liquid can be classified and diverted into organic solution, heavy metal salt solution and acid and alkali solution, and stored separately, which improves the use effect. At the same time, the whole has a pull-out design. The collection liquid box 121 inside the box body 101 can be pulled out and operated, which is convenient for processing and dumping.

[0053] The liquid collecting box 121 can be connected and separated by the diverter liquid inlet mechanism that can be raised and lowered. The overall separation and connection effects are good, and it is easy to use and can be automatically opened and closed. At the same time, the overall sealing effect is good, with good sealing, which can reduce the overflow of volatile gases. The rubber sealing ring 133 is clamped by the end ring 132 and the chimeric sleeve 136 to provide a first seal, and the rubber cushion 134 is further clamped by the chimeric sleeve 136 and the horn cover 129 to provide a second seal. At the same time, an activated carbon adsorption layer 135 is provided on the horn cover 129, and a baffle 137 is also provided, thereby forming a gap, which provides a flow channel for the overflow gas, which can be adsorbed by the activated carbon adsorption layer 135, further reducing the overflow of volatile gases and entering the box body 101, greatly reducing the overflow of volatile gases.

[0054] At the same time, the box body 101 is sealed by the side door panel 103, and a rubber sleeve 138 is added to the side door panel 103 to fill the gap and provide sealing, thereby improving the sealing effect. At the same time, it has a negative pressure exhaust mechanism 105, which can provide negative pressure adsorption for the inside of the box body 101, thereby further avoiding the overflow of volatile gases. At the same time, the negative pressure exhaust mechanism 105 has a filtering structure, which can provide a filtering effect to avoid the volatile gases being directly discharged to the outside during negative pressure adsorption.

[0055] In summary, in this application, the volatile gas is difficult to escape and is not easily discharged to the outside.

[0056] Each collection liquid box 121 has a specific slot structure, so that each collection liquid box 121 can only be fixed in a specified position and cannot be placed in other positions to avoid mixing and causing diversion errors. A gyroscope 117 is also provided to facilitate the determination of the movement or static state of the entire device.

[0057] The foregoing description is merely a specific embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
