DETAILED DESCRIPTION
[0018] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.
[0019] The utility model provides a self-sealed recovery barrel for preventing the volatilization of residual liquid used for sampling of a 1.4-butanediol device, comprising a barrel body 1, a handle 2 arranged on the top of the barrel body 1 and a barrel cover 3, the barrel cover 3 being connected to the barrel body 1 by threads, a connecting hole 4 being provided on the barrel cover 3, a drain pipe 5 being fixedly connected in the connecting hole 4, a drain port 6 being provided on one side of the bottom of the drain pipe 5, a sealing plate 7 cooperating with the drain port 6 being rotatably connected to the top of the drain port 6, a funnel 8 being provided on the top of the barrel cover 3, the funnel 8 being connected to the drain pipe 5, the bottom of the drain pipe 5 being inclined toward the drain port 6, so as to avoid residual liquid being left in the drain pipe 5.
[0020] like Figure 1-3 As shown, the anti-volatile self-sealed recovery barrel for liquid sampling and replacement of residual liquid in the production process of 1.4-butanediol (BDO) uses a chemical plastic barrel as a containing container, and is equipped with an anti-volatile self-sealed barrel cover 3. The barrel cover 3 is a barrel cover 3 selected to be compatible with chemical plastic barrels. A connecting hole 4 is opened on the barrel cover 3 to fix the drainage pipe 5. When collecting residual liquid on a daily basis, the barrel cover 3 is installed on the barrel body 1, and the funnel 8 is placed on the drainage pipe 5, and then the residual liquid is poured into the funnel 8. The sealing plate 7 is opened by the self-gravity of the residual liquid. After the residual liquid flows into the barrel body 1, the sealing plate 7 is automatically sealed to achieve anti-volatile, anti-corrosion and anti-unorganized emission. After the residual liquid in the barrel body 1 is full, the barrel cover 3 is replaced with a new barrel body 1 to continue to hold the residual liquid. The barrel body 1 filled with residual liquid is sealed and transferred and recycled using an ordinary barrel cover without holes.
[0021] Mounting seats 9 are fixedly connected to the two ends of the outer wall of the liquid discharge pipe 5 and located above the liquid discharge port 6 , and a rotating shaft 10 is fixedly connected to the top of the sealing plate 7 , and the rotating shaft 10 is rotatably mounted in the mounting seats 9 .
[0022] like Figure 4 As shown, both ends of the rotating shaft 10 are rotatably installed in the mounting seat 9. When residual liquid passes through, the sealing plate 7 will rotate a certain angle with the rotating shaft 10 as the axis. When no residual liquid passes through, the sealing plate 7 will be retracted under its own gravity to cover the drain port 6.
[0023] A support plate 11 is fixedly connected inside the discharge pipe 5 and above the discharge port 6, and a through hole 12 is opened on the support plate 11 to match the discharge pipe of the funnel 8. Storage chambers 13 are symmetrically arranged on both sides of the discharge pipe 5, and seals are slidably installed in the storage chambers 13. The discharge pipe at the bottom of the funnel 8 passes through the seal and is connected to the through hole 12; the seal includes a sealing plate 2 14 and a reset spring 15 and a slider 16 installed in the storage chamber 13. The sealing plate 2 14 is slidably installed on the support plate 11, one end of the slider 16 is connected to the sealing plate 2 14 by a plurality of sliding rods 17, and the other end of the slider 16 is fixedly connected to the reset spring 15.
[0024] like Figure 3 and 5 As shown, there are two slide bars 17, and the through hole 12 is sealed by a seal, which can play a double sealing role for the residual liquid in the recovery barrel. When the residual liquid is not collected, the two sealing plates 14 are pressed together under the action of the reset spring 15 to cover the through hole 12; when collecting the residual liquid daily, the funnel 8 is placed in the discharge pipe 5, and the funnel 8 is pressed down. The discharge pipe of the funnel 8 moves the two sealing plates 14 toward the corresponding storage chamber 13 respectively. At this time, the discharge pipe at the bottom of the funnel 8 is between the two sealing plates 14, and its discharge end is inserted into the through hole 12. The sealing plates 14 and the through hole 12 also play the effect of fixing the funnel 8.
[0025] A second sliding block 18 is fixedly connected to the bottom of the second sealing plate 14 , and a sliding groove 19 adapted to the second sliding block 18 is provided on the support plate 11 , and the sliding groove 19 is arranged parallel to the sliding rod 17 .
[0026] like Figure 5 As shown, the slider 18 and the slide groove 19 are used to improve the stability of the sealing plate 14 when sliding.
[0027] The discharge port at the bottom of the discharge pipe of the funnel 8 is in the shape of an inclined surface, and the tops of the opposite surfaces of the two sealing plates 14 are both provided with semi-funnel-shaped grooves 20.
[0028] like Figure 2 and 3 As shown, the discharge port at the bottom of the discharge pipe of the funnel 8 is set to be inclined, and the end is pointed. The semi-funnel-shaped grooves 20 on the top of the two sealing plates 14 are combined into a funnel-shaped structure, which can conveniently separate the two sealing plates 14 that are in contact with each other and facilitate the discharge pipe of the funnel 8 to be inserted into the groove 20. When force is applied to the top of the funnel 8, the reset spring 15 contracts, and the two sealing plates 14 move back to back, so that the discharge port of the discharge pipe of the funnel 8 is completely inserted into the through hole 12.
[0029] Principle of use: When collecting residual liquid on a daily basis, install the barrel cover 3 on the barrel body 1 with threads, and place the funnel 8 on the discharge pipe 5, press the funnel 8 downward, the discharge pipe of the funnel 8 separates the two sealing plates 14, and the discharge port passes through the sealing plate 14 and is inserted into the through hole 12, then pour the residual liquid into the funnel 8, and the sealing plate 7 is opened by the gravity of the residual liquid. After the residual liquid flows into the barrel body 1, the sealing plate 7 is automatically sealed to achieve anti-volatilization, anti-corrosion and anti-unorganized emission. After the residual liquid in the barrel body 1 is filled, the barrel cover 3 is replaced with a new barrel body 1 to continue to hold the residual liquid. The barrel body 1 filled with residual liquid is sealed and transferred and recycled using an ordinary unperforated barrel cover; when the residual liquid is not poured into the funnel 8, the two sealing plates 14 are in contact with each other under the elastic action of the return spring 15 to cover the through hole 12, and the sealing plate 1 7 will automatically seal the discharge port 6. Through the double sealing of the discharge pipe 5, the occurrence of residual liquid volatilization can be effectively avoided.
[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
