[0015] The beneficial effects of the present invention are as follows:

[0016] 1. When the present invention collects waste liquid, first lift the top block to the side, add waste liquid into the enclosure, the waste liquid in the enclosure is led to the connecting piece, the waste liquid hits and squeezes the connecting piece, causing the connecting piece to shake, the waste liquid hits and squeezes the connecting piece to move the connecting piece downward, the waste liquid is led to the lower end of the enclosure, the connecting piece moves downward to press the sticking block, the sticking block moves downward until the length of the sticking block body reaches the lower end of the enclosure, the lower end of the enclosure approaches the sticking block, the impurity removal block moves with the movement of the sticking block, the impurity removal block attracts the solid matter in the waste liquid and makes it adhere to the impurity removal block, the sticking block presses the waste accumulated at the lower end of the enclosure The liquid level is measured, and the waste liquid is guided to the second guide channel. A transducer is installed on the installation cover. The transducer is a device that can output the sensed pressure signal as an electrical signal. When the transducer on the installation cover monitors the pressure in the guide channel and raises it to a preset pressure, the collection device is operated, and the waste liquid is guided to the connecting block through one end of the corner position on the second guide channel, and then guided into the guide unit along the connecting block, so that the operator can collect and transfer the waste liquid from the bottom of the guide unit, so as to monitor the waste liquid collection degree of the device, avoid the collected waste liquid amount exceeding the holding degree of the device, and facilitate the operation.

[0017] 2. The present invention is beneficial to change the degree of separation of the poisonous gas in the inner chamber through the impurity removal unit. The waste liquid and the poisonous gas are guided to the connection cover through the support block. If the poisonous gas in the connection cover is not properly handled, the poisonous gas is easily guided out from the middle of the receiving block, so the flow rate of the poisonous gas should be slowed down. The waste liquid is guided to the connection cover, and the connection block is squeezed. The connection block blocks the waste liquid, the connection block is deformed, the connection block tends to shift, and the connection block moves from right to left along the inner wall of the connection cover. The connection block is pressed against the transmission block and the stacking block. The stacking block is composed of a plurality of laminates, and the stacking block is pushed by the connection block. The two blocks are close to each other, the transmission block 1 is attached to the receiving block, and several transmission blocks are initially gathered toward the center. The transmission block 1 is stretched through the receiving block, and the spiral beryllium copper wire on the connecting block 1 is transformed from the initial tightened state to the stretched state. The support block moves toward the outside of the center with the transmission block 1. When the transmission block is stretched, it moves together with the support block, and the support block is pressed against the inner wall of the connecting cover 1. The stretching of the support block is beneficial to prevent the poisonous gas inside from being quickly discharged by the receiving block, which slows down the flow rate of the poisonous gas, helps to reduce the emission rate of the poisonous gas, and enhances the safety of laboratory waste liquid collection.

[0018] 3. When the present invention is used to inhibit the export of poisonous gas, the poisonous gas is guided to the center of the receiving block through the support block and the first transmission block, and then into the enclosure. The poisonous gas adheres to the second transmission block and enters through the installation opening one reserved on the elastic cover. The elastic cover is elastic. When the poisonous gas fills the inside of the elastic cover, the volume of the elastic cover expands. After the volume of the elastic cover expands, it squeezes the pressing block. The pressing block moves into the inner chamber of the second transmission block, enhancing the smoothness of the inner wall surface. The supporting chamber supports the elastic cover. When the pressing block stops at the inner wall of the second transmission block, the second transmission block vibrates, facilitating the operator to know that the device is in the stage of inhibiting the export of poisonous gas. When the vibration sound becomes louder, the operator can divert some of the collected laboratory waste liquid, which helps to reduce the export rate of the overflowing poisonous gas in the collected laboratory waste liquid and enhance the safety of collecting laboratory waste liquid.

[0019] 4. When the present invention is collecting laboratory waste liquid, the device is operated. The waste liquid enters through the third transmission block and then into the second connecting cover. The waste liquid in the second connecting cover has a moving rate. The waste liquid in the third transmission block squeezes the transmission piece and moves. The transmission piece rotates, and the waste liquid rotating on the transmission piece spreads evenly in the second connecting cover to prevent the solids in the waste liquid from coming out. The waste liquid collides with the second connecting block, and the second connecting block attracts the solids in the waste liquid and makes them adhere to the second connecting block, distinguishing the waste liquid with solids. Then the waste liquid is further guided into the support block for pre-treatment of the collected laboratory waste liquid, reducing the content of solids in the collected waste liquid, so as to facilitate subsequent disposal by the operator.

The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figures 1 - 10 The embodiment of the present invention provides a laboratory waste liquid collection device, comprising a supporting block 2, the upper end of the supporting block 2 is fixedly connected to a vertical block 3, and a cover 4 is movably mounted on the upper end of the vertical block 3, and the degree of differentiation of the collected waste liquid is changed through the cover 4;

[0035] The housing 4 includes an enclosure 42. A middle tube 43 is installed on the outer wall surface of the enclosure 42. A ring block 44 is fixedly connected to the lower part of the inner chamber of the enclosure 42. The upper part of the guiding unit 5 is fixedly connected to a connecting block 47. A second guiding path 45 is installed in the connecting block 47. An installation cover 46 is installed above the second guiding path 45. A bearing block 48 is installed on the side wall surface of the installation cover 46. A connecting piece 49 is movably installed at the end of the bearing block 48 farther away from the installation cover 46. A sticking block 410 is movably installed at the lower part of the connecting piece 49. The lower part of the sticking block 410 extends downward by the length of the sticking block 410 body and reaches below the enclosure 42. The lower part of the enclosure 42 approaches the sticking block 410. The impurity removing block 41 moves along with the movement of the sticking block 410. The impurity removing block 41 attracts the solid substances in the waste liquid and makes them adhere to the impurity removing block 41. The impurity removing block 41 is movably installed on the outer wall surface of the sticking block 410. The impurity removing block 41 is a black porous solid carbonaceous material. The second guiding path 45 is installed in the connecting block 47. The installation cover 46 is connected to the connecting block 47 through the second guiding path 45.

[0036] First, lift the top block 7 aside and pour the waste liquid into the enclosure 42. The waste liquid in the enclosure 42 is guided to the connecting piece 49, and the waste liquid impacts and squeezes the connecting piece 49, causing the connecting piece 49 to shake.

[0037] The waste liquid impacts and squeezes the connecting piece 49, causing the connecting piece 49 to move downward. The waste liquid is guided to the lower part of the enclosure 42. The connecting piece 49 moves downward and presses the sticking block 410. The lower part of the sticking block 410 extends downward by the length of the sticking block 410 body and reaches below the enclosure 42. The lower part of the enclosure 42 approaches the sticking block 410. The impurity removing block 41 moves along with the movement of the sticking block 410. The impurity removing block 41 attracts the solid substances in the waste liquid and makes them adhere to the impurity removing block 41. The sticking block 410 measures the liquid level of the waste liquid accumulated at the lower part of the enclosure 42. The waste liquid is guided into the second guiding path 45. A transducer is installed on the installation cover 46. The transducer is a device that can output the sensed pressure signal as an electrical signal. The model of the transducer is NPA - 700B - 10WD. When the transducer on the installation cover 46 monitors that the pressure in the guiding path rises to the preset pressure, the collection device operates. The waste liquid is guided to the connecting block 47 through one end of the turning position on the second guiding path 45 and then guided into the guiding unit 5 along the connecting block 47, so that the operator can collect and transfer the waste liquid from below the guiding unit 5, monitor the waste liquid collection degree of the monitoring device, avoid the amount of collected waste liquid exceeding the holding capacity of the device, and make the operation convenient.

[0038] An impurity removing unit 6 is movably installed on the outer wall surface of the housing 4. Both the impurity removing unit 6 and the transmission unit 8 are installed in the inner chamber of the housing 4. The impurity removing unit 6 is beneficial to changing the guiding degree of the poisonous gas in the inner chamber;

[0039] The impurity removal unit 6 includes a first briquette 62. The inner wall surface of the first briquette 62 is fixedly connected with a first connecting cover 64. Waste liquid and poisonous gas are led into the first connecting cover 64 through a support block 65. If the poisonous gas in the first connecting cover 64 is not properly disposed of, the poisonous gas is easily discharged from the middle part of the receiving block 66. A first connecting block 63 is movably installed on the inner chamber wall surface of the first connecting cover 64. The first connecting block 63 blocks the waste liquid. When the first connecting block 63 is deformed and tends to shift, the first connecting block 63 moves from right to left along the inner wall of the first connecting cover 64. The first connecting block 63 presses against a first driving block 69 and a stacked block 68. A spiral beryllium copper wire is installed on the first connecting block 63. A first driving block 69 is movably installed at the end of the first connecting block 63 farther from the first briquette 62. A support block 65 is movably installed outside the first driving block 69. A receiving block 66 is fixedly connected to the end of the first connecting cover 64 closer to the support block 65. A sealing unit 67 is movably installed on the outer wall surface of the receiving block 66. The support block 65 is located inside the first connecting cover 64. A stacked block 68 is installed in the middle of the first connecting block 63. Sealing units 67 are movably installed on both the front and back sides of the stacked block 68. The sealing units 67 are located outside the stacked block 68.

[0040] The receiving block 66 and the first connecting cover 64 form a right angle. The first connecting block 63 is connected to the receiving block 66 through the stacked block 68. Waste liquid and poisonous gas overflowing from the waste liquid are led into the first connecting cover 64 through the support block 65. If the poisonous gas in the first connecting cover 64 is not properly disposed of, the poisonous gas is easily discharged from the middle part of the receiving block 66.

[0041] The sealing unit 67 includes a ring cover 672. A second driving block 673 is movably installed in the inner chamber of the ring cover 672. A supporting chamber 674 is movably installed in the inner chamber of the second driving block 673. An elastic cover 675 is movably installed on the outer wall surface of the supporting chamber 674. An pressing block 676 is fixedly connected to the outer wall surface of the elastic cover 675. The pressing block 676 moves into the inner chamber of the second driving block 673. The pressing block 676 enhances the smoothness of the inner wall surface. The supporting chamber 674 supports the elastic cover 675. An installation opening one is reserved on the inner wall surface of the elastic cover 675. The installation opening two reserved on the elastic cover 675 has the same size as the supporting chamber 674. The second driving block 673 is installed inside the ring cover 672. The size of the second driving block 673 is larger than that of the supporting chamber 674. The supporting chamber 674 passes through the inside of the second driving block 673.

[0042] The waste liquid and poisonous gas are led to the first connecting cover 64 through the supporting block 65. If the poisonous gas in the first connecting cover 64 is not properly disposed of, the poisonous gas is easily discharged from the exact middle of the receiving block 66. Therefore, it is necessary to slow down the moving rate of the poisonous gas. The waste liquid is led to the first connecting cover 64, squeezing the first connecting block 63. The first connecting block 63 blocks the waste liquid, the first connecting block 63 deforms, the first connecting block 63 tends to shift, and the first connecting block 63 moves from right to left along the inner wall of the first connecting cover 64. The first connecting block 63 presses against the first driving block 69 and the laminated block 68. The laminated block 68 is composed of several laminated sheets. The laminated block 68 is pressed by the first connecting block 63 and approaches each other. The first driving block 69 is in contact with the receiving block 66. Several first driving blocks 69 are initially gathered towards the center. The first driving block 69 expands through the receiving block 66. The spiral beryllium copper wire on the first connecting block 63 changes from the initial tightened state to the expanded state. The supporting block 65 moves outward towards the center following the first driving block 69. The first driving block 69 expands and moves together with the supporting block 65. The supporting block 65 presses against the inner wall surface of the first connecting cover 64. The expansion of the supporting block 65 helps to prevent the poisonous gas inside from being quickly led away from the receiving block 66, slows down the moving rate of the poisonous gas, helps to reduce the discharge rate of the poisonous gas, and enhances the safety of laboratory waste liquid collection.

[0043] When inhibiting the discharge of poisonous gas, the poisonous gas is led to the middle position of the receiving block 66 through the supporting block 65 and the first driving block 69. The poisonous gas is led into the circular cover 672. The poisonous gas is in contact with the second driving block 673 and is led in through the first installation opening reserved on the elastic cover 675. The elastic cover 675 has elasticity. The poisonous gas filled inside the elastic cover 675 causes the volume of the elastic cover 675 to expand. After the volume of the elastic cover 675 expands, it presses against the pressing block 676. The pressing block 676 moves closely into the inner chamber of the second driving block 673. The pressing block 676 enhances the smoothness of the inner wall surface. The supporting chamber 674 supports the elastic cover 675. When the pressing block 676 blocks against the inner wall of the second driving block 673, the second driving block 673 vibrates, which is convenient for the operator to know that the device is in the stage of inhibiting the discharge of poisonous gas. When the vibration sound becomes louder, the operator can lead away some of the collected laboratory waste liquid, which helps to reduce the discharge rate of the overflowing poisonous gas in the collected laboratory waste liquid and enhances the safety of laboratory waste liquid collection.

[0044] The driving unit 8 is installed on the outer wall surface of the housing 4. The impurity removal unit 6 corresponds to the driving unit 8. The driving unit 8 helps to improve the impurity removal rate of the waste liquid during laboratory waste liquid collection. The top block 7 is installed on the top of the housing 4. The guiding unit 5 is installed at the bottom of the housing 4. The guiding unit 5 penetrates into the inner chamber of the housing 4. An inner chamber is reserved in the housing 4;

[0045] The transmission unit 8 includes a second pressing block 82. The inner wall surface of the second pressing block 82 is fixedly connected with a second connecting cover 83. One end of the second connecting cover 83 farther from the second pressing block 82 is fixedly connected with a connecting block 84. A third transmission block 85 is movably arranged at the center of the connecting block 84. Inside the third transmission block 85, a waste liquid extrusion transmission piece 87 moves, and the transmission piece 87 rotates. The waste liquid rotating the transmission piece 87 spreads evenly inside the second connecting cover 83. One end of the connecting block 84 farther from the third transmission block 85 is rotatably connected with the transmission piece 87. One end of the connecting block 84 closer to the transmission piece 87 is fixedly connected with several second connecting blocks 86. The transmission piece 87 is located outside the center of the connecting block 84, and a first installation opening is reserved in the second connecting block 86.

[0046] During the stage of collecting laboratory waste liquid, the operating device is run, and the waste liquid is introduced into the third transmission block 85 and then led into the second connecting cover 83. There is a moving rate of the waste liquid in the second connecting cover 83. Inside the third transmission block 85, the waste liquid extrudes the transmission piece 87 and moves, and the transmission piece 87 rotates. The waste liquid rotating the transmission piece 87 spreads evenly inside the second connecting cover 83 to prevent solids in the waste liquid from coming out. The waste liquid collides with the second connecting blocks 86, and the second connecting blocks 86 attract the solids in the waste liquid and make them adhere to the second connecting blocks 86. The waste liquid mixed with solids is separated, and then the waste liquid is led into the support block 65 for pre-treatment of the collected laboratory waste liquid, reducing the content of solids mixed in the collected waste liquid, so as to facilitate subsequent operators to dispose of the waste liquid.
