It overcomes the defects of traditional material lab benches that are prone to rust, yellowing, and cracking when in contact with corrosive substances. It is suitable for all types of high-cleanliness laboratories.
[0003] When conducting combustion operation experiments, the PP test bench usually needs to use a container to heat and melt the material. Since the container will absorb heat and conduct it to the test bench, the test bench is exposed to high temperature for a long time and is prone to deformation, resulting in a reduction in its physical properties. When subsequent combustion experiments are carried out, the flame retardant effect of the damaged test bench is reduced, and there is a risk of ignition, which can easily lead to accidents.

[0036] Example
[0037] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide a highly flame-retardant PP experimental table, including an experimental table body 1, a water intake trough 2 is arranged on the top of the experimental table body 1, a first experimental table 11 is arranged outside the water intake trough 2, a storage component 3 is arranged on the top of the first experimental table 11 for placing materials, a waste material trough 4 is provided on the top of the first experimental table 11, an installation groove is provided on the inner wall of the first experimental table 11, a rotating block 5 is rotatably installed inside the installation groove, a second experimental table 51 is fixedly installed at one end of the rotating block 5, and the second experimental table 51 is made of a ceramic table top;
[0038] Furthermore, by setting a water intake trough 2 on the top of the experimental table body 1, the water pipe can be connected to facilitate the experimenter to take water. A first experimental table 11 for experiment is set on the top of the experimental table body 1. The first experimental table 11 is set on the side of the water intake trough 2. The first experimental table 11 can be used for ordinary reaction experiments. When a combustion experiment is needed, the second experimental table 51 can be rotated so that the second experimental table 51 falls on the top of the first experimental table 11. The second experimental table 51 is made of ceramic table top material, which can play a high-efficiency flame retardant effect, so that the experimental table can be switched and replaced according to different experimental needs, so that the PP experimental table can play a high-efficiency flame retardant effect.
[0039] A connecting block 6 is fixedly installed on the top of the experimental table body 1, and a closing plate 61 is rotatably installed on the outside of the connecting block 6. A leakage hole is opened on the front of the closing plate 61, and a docking joint 62 is installed inside the leakage hole for connecting a water pipe. A docking plate 63 is fixedly installed on the front of the closing plate 61, and the closing plate 61 is used to close the top of the second experimental table 51.
[0040] Furthermore, a connecting block 6 is installed on the top of the experimental table body 1, so that the closing plate 61 can be hinged on the outer side of the connecting block 6 and rotated. When the second experimental table 51 is conducting a combustion experiment, if an uncontrollable situation such as the flame cannot be extinguished occurs, the closing plate 61 can be rotated to cover the top of the second experimental table 51, and the burning part on the surface of the second experimental table 51 is closed. A leakage hole is opened on the front side of the closing plate 61, and a joint 62 can be installed inside the leakage hole to connect the water pipe. Water can be injected between the second experimental table 51 and the closing plate 61 to extinguish the burning material, thereby achieving a high flame retardant and fireproof effect.
[0041] It should be noted that a support plate 8 is fixedly installed at the bottom of the second experimental table 51, and the support plate 8 is arranged on the top of the first experimental table 11, and is used to support and place the second experimental table 51. The support plate 8 can make the second experimental table 51 horizontally placed on the top of the first experimental table 11. The connecting block 6 and the rotating block 5 and the rotating shaft of the closing plate 61 and the second experimental table 51 adopt a damping rotating shaft, which can suspend and fix the closed plate 61 and the second experimental table 51 after rotation.
[0042] First, consider the problem of how the water flows out after being injected into the second experimental table 51. Figure 2 , Figure 5 and Figure 6 A filter screen 41 is installed inside the waste tank 4, and a drain port 42 is opened at the bottom of the waste tank 4 for discharging waste liquid.
[0043] A leaking hole 52 is provided on the top of the second experimental table 51 . The leaking hole 52 is arranged above the waste tank 4 and is used to collect the liquid flowing down from the leaking hole 52 .
[0044] Furthermore, by opening a waste trough 4 on the first experimental table 11, experimental waste and waste liquid can be poured into the waste trough 4, screened by the filter screen 41 in the waste trough 4, and fixed waste can be collected. The filter screen 41 can be disassembled to facilitate subsequent unified treatment. The waste is discharged into the collection device through the drain port 42 at the bottom, and the waste liquid is uniformly treated to avoid being poured into the water intake trough 2 and polluted. In addition, a leakage hole 52 is opened on the top of the second experimental table 51, so that the waste poured out from the second experimental table 51 can flow into the waste trough 4, and when water is injected into the second experimental table 51 through the closing plate 61, the water source can flow into the waste trough 4 through the leakage hole 52, thereby achieving the effect of processing and collecting the water used for experimental fire extinguishing and experimental waste.
[0045] Secondly, considering the problem of how to place the experimental materials, Figure 1 , the specific structure of the storage component 3 is disclosed. The storage component 3 includes a blocking plate 301 fixedly installed on the top of the experimental table body 1, and a storage board 302 is fixedly installed on one side of the blocking plate 301 close to the first experimental table 11. A plurality of storage boards 302 are provided for placing objects.
[0046] The blocking plate 301 is configured to be L-shaped, a threading hole is provided on the top of the blocking plate 301, a connecting hole 7 is provided on the front of the blocking plate 301, a connecting column 601 is fixedly installed on the back of the closing plate 61, a connecting head is installed inside the connecting column 601, and the connecting column 601 is plugged into the inside of the connecting hole 7.
[0047] By installing a blocking plate 301 on the top of the experimental table body 1, the storage plate 302 can be fixedly installed so that materials can be placed on the storage plate 302 for storage, and a wire threading hole is opened inside the blocking plate 301, and the wires can be laid, and the switch socket on the experimental table body 1 can be energized to achieve the effect of energizing the materials and the experimental table body 1; the closing plate 61 is only rotated when the flame of the second experimental table 51 is uncontrollable. Under normal circumstances, the closing plate 61 remains stationary and the circuit equipment in the experimental table body 1 is energized.
[0048] It should be noted that the circuit inside the blocking plate 301 is disconnected. The wires inside the blocking plate 301 can be connected only by inserting the connecting column 601 on the back of the closing plate 61 into the connecting hole 7 opened on the blocking plate 301. When the second experimental table 51 encounters an uncontrollable fire, the second experimental table 51 is closed by rotating the closing plate 61 to block the oxygen inside, and the flame is extinguished by injecting water. When the second experimental table 51 catches fire, it will affect the circuit device. After rotating the closing plate 61, the connecting column 601 will be pulled out of the connecting hole 7, and the wires will no longer be connected. The circuit device on the experimental table body 1 can be powered off to avoid circuit fire and leakage, thereby further blocking the flame.
[0049] Finally, show Figure 1 and Figure 4 The experimental table body 1 is made of polypropylene. Two first experimental tables 11 are provided, and the two first experimental tables 11 are symmetrically distributed on both sides of the water tank 2, and experimental operations can be performed separately.
[0050] The experimental table body 1 is made of polypropylene material, and the second experimental table 51 and the closing plate 61 are made of ceramic tabletops, which can block the flame and prevent the flame from damaging the experimental table. The first experimental table 11 and the second experimental table 51 can be rotated and switched, which is easy to operate.
[0051] In summary, the working principle of this scheme is as follows:
[0052] When the experimental table is used, a non-heating reaction experiment can be operated on the first experimental table 11, and the waste generated by the experiment can be poured into the waste tank 4 for filtering and collection. When a heating experiment is required, the second experimental table 51 is rotated so that the second experimental table 51 covers the top of the first experimental table 11. The second experimental table 51 uses a ceramic table top, which can block the flame generated by the heat and avoid damage to the experimental table body 1, thereby achieving the flame retardant effect of the PP experimental table;
[0053] When uncontrollable flame combustion occurs on the second experimental table 51, the top of the second experimental table 51 can be closed by rotating the closing plate 61, so that the second experimental table 51 forms a sealed space to block oxygen and the burning flame, and water can be injected into the second experimental table 51 through the docking joint 62 on the closing plate 61 to extinguish the flame. When the closing plate 61 is rotated to close the second experimental table 51, the wires in the connecting hole 7 are no longer connected, and the circuit device on the experimental table body 1 can be powered off to avoid leakage caused by flame combustion, and the flame burning on the experimental table can be blocked from burning.
