Description

Technical Field

[0001] This utility model relates to the field of methanol recovery technology, and in particular to an emergency adsorption and recovery device for methanol leakage. Background Technology

[0002] Chemicals refer to pure substances and mixtures composed of different elements (chemical elements), including both naturally occurring substances and artificially synthesized or manufactured chemical substances. Methanol (chemical formula: CH3OH / CH4O) is the simplest saturated monohydric alcohol, a colorless and transparent liquid at room temperature with a pungent odor. Because it was first discovered through the dry distillation of wood, it is also known as "wood alcohol" or "wood spirit." Methanol is a basic raw material for many organic products such as formaldehyde, acetic acid, methylamine, and dimethyl sulfate, and is widely used in plastics, coatings, explosives, and textile treatment agents.

[0003] Because methanol is volatile and highly toxic, when methanol leaks, personnel in the leak area and downwind should be evacuated to a safe zone immediately. Small-scale leaks can be sealed with sand, lime, or special absorbent materials. In addition, a rotating recovery device is needed to recover the methanol. Based on this, an emergency adsorption and recovery device for methanol leaks is proposed to realize the emergency recovery of leaked methanol. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an emergency adsorption and recovery device for methanol leakage, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a methanol leakage emergency adsorption and recovery device, including a mobile platform. A recovery tank is installed on one side of the top surface of the mobile platform, and a support frame is installed on the other side of the top surface of the mobile platform. An explosion-proof pump and a rotatable cantilever mounting rod are installed on the top surface of the support frame. The input and output ends of the explosion-proof pump are respectively connected to a first antistatic pipe and a second antistatic pipe. A conical cover is installed at the other end of the first antistatic pipe. Universal wheels are installed on all four sides of the conical cover. A conical plug is installed inside the conical cover. An operating rod is rotatably installed on one side of the middle of the conical cover. Connecting wires are installed at one corner of the top surface of the mobile platform, one corner of the top surface of the support frame, and one side of the middle of the conical cover, and grounding bodies are installed at the ends of all three.

[0006] Preferably, of any of the above solutions, the recovery tank has an injection port on the side near the top surface of the support frame, and a float is slidably installed on the other side of the top surface of the recovery tank. This solution allows the operator to easily insert the second antistatic tube into the inside of the recovery tank through the injection port, making it easy to hold the recovered methanol in the recovery tank, while the float allows for observation of the liquid level inside the recovery tank.

[0007] Preferably, one end of the cantilever mounting rod is slidably fitted with a pin, the bottom end of which is slidably connected to the top end of the support frame. This design facilitates the insertion of the pin into the support frame, limits the position of the cantilever mounting rod, and prevents accidental slippage during the movement of the platform. After the pin is removed, the cantilever mounting rod can be rotated at a certain angle, providing stable support for the first antistatic tube and preventing the first antistatic tube from contacting and rubbing against the ground during movement.

[0008] Preferably, in any of the above solutions, the middle part of the cantilever mounting rod is hollowed out, and the first antistatic tube is fixedly connected to the top surface of the cantilever mounting rod by a pipe clamp. This solution helps to reduce the relative weight of the cantilever mounting rod and facilitates the rotation of the cantilever mounting rod at a certain angle by the first antistatic tube, so that the cantilever mounting rod faces the direction of the conical cover and provides stable support for the first antistatic tube.

[0009] Preferably, in any of the above schemes, a gap is left between the outer wall of the conical plug and the inner wall of the conical cover, and the conical plug is fixedly connected to the inner wall of the conical cover by screws. By using this scheme, it is easy to leave a certain distance between the conical plug and the conical cover, so that the methanol feeding area becomes annular. When the explosion-proof pump is powered on, the arc-shaped area between the conical plug and the conical cover will form a low negative pressure area, which is convenient for methanol to be drawn in.

[0010] This utility model has the following advantages:

[0011] 1. This methanol leakage emergency adsorption and recovery device consists of a recovery tank, an explosion-proof pump, and a conical cover. The explosion-proof pump is connected to the top of the conical cover via a first anti-static pipe. The conical cover is equipped with casters on all four sides, and an operating lever is rotatably mounted in the center. The operator holds the operating lever to guide the conical cover into the methanol accumulation area. Simultaneously, the explosion-proof pump is powered on, facilitating the suction of methanol into the recovery tank, thus achieving the purpose of recovering leaked methanol. The overall structure is simple, easy to operate, and convenient for widespread use.

[0012] 2. This methanol leakage emergency adsorption and recovery device features a support frame with a cantilevered mounting rod on one side of its top. The cantilevered mounting rod is horizontally positioned to provide support for the first antistatic tube. Simultaneously, when the operator moves the conical cover, the cantilevered mounting rod can rotate at a certain angle with the antistatic tube, facilitating methanol absorption. Three connecting wires and a grounding electrode are installed, with the three connecting wires electrically connected to the moving platform, support frame, and conical cover respectively. This facilitates the dissipation of static electricity generated during operation, which is then conducted to the ground via the grounding electrode, ensuring safety during the absorption process.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0021] like Figures 1 to 6 As shown, an emergency adsorption and recovery device for methanol leakage includes a mobile platform 1. A recovery tank 2 is installed on one side of the top surface of the mobile platform 1, and a support frame 7 is installed on the other side of the top surface of the mobile platform 1. An explosion-proof pump 5 and a rotatable cantilever mounting rod 6 are installed on the top surface of the support frame 7. The input and output ends of the explosion-proof pump 5 are respectively connected to a first antistatic pipe 13 and a second antistatic pipe 4. A conical cover 9 is installed at the other end of the first antistatic pipe 13. Universal wheels 8 are installed on all four sides of the conical cover 9. A conical plug 14 is installed inside the conical cover 9. An operating device is rotatably installed on one side of the middle of the conical cover 9. Connecting wires 11 are installed on one corner of the top surface of the rod 10, one corner of the top surface of the support frame 7, and one side of the middle of the conical cover 9. Grounding bodies 12 are installed at the ends of the three. The bottom end of the grounding body 12 is provided with a sharp corner. It is made of steel single rod material and the surface is galvanized to prevent corrosion during use. Both ends of the three connecting wires 11 are crimped with wire lugs, so that the two ends of the connecting wires 11 can be electrically connected to the mobile platform 1, the support frame 7 and the conical cover 9 respectively with bolts, so as to facilitate the timely discharge of static electricity generated during use.

[0022] An injection port is provided on one side of the recovery tank 2 near the top surface of the support frame 7, and a float 3 is slidably installed on the other side of the top surface of the recovery tank 2. As an optional technical solution of this utility model, this makes it easy for the operator to insert the second antistatic tube 4 into the inside of the recovery tank 2 from the injection port. The recovery tank 2 is convenient for holding the recovered methanol, and at the same time, the liquid level inside the recovery tank 2 can be observed through the float 3.

[0023] A pin 15 is slidably installed at one end of the cantilever mounting rod 6. The bottom end of the pin 15 is slidably connected to the top end of the support frame 7. As an optional technical solution of this utility model, this facilitates the insertion of the pin 15 into the support frame 7, which facilitates the positioning of the cantilever mounting rod 6 and prevents accidental sliding during the pushing of the mobile platform 1. After the pin 15 is removed, the cantilever mounting rod 6 can be rotated at a certain angle, which facilitates the stable support of the first antistatic tube 13 and avoids the first antistatic tube 13 from contacting and rubbing against the ground during the movement.

[0024] The middle part of the cantilever mounting rod 6 is hollowed out. The first antistatic tube 13 is fixedly connected to the top surface of the cantilever mounting rod 6 through a tube clamp. As an optional technical solution of this utility model, this makes it easier to reduce the relative weight of the cantilever mounting rod 6 and to drive the cantilever mounting rod 6 to rotate at a certain angle through the first antistatic tube 13, so that the cantilever mounting rod 6 faces the direction of the conical cover 9 and provides stable support for the first antistatic tube 13.

[0025] A gap is left between the outer wall of the conical plug 14 and the inner wall of the conical cover 9. The conical plug 14 is fixedly connected to the inner wall of the conical cover 9 by screws. As an optional technical solution of this utility model, this makes it easier to leave a certain distance between the conical plug 14 and the conical cover 9, so that the methanol feeding area becomes an annular area. When the explosion-proof pump 5 is powered on, the arc-shaped area between the conical plug 14 and the conical cover 9 will form a low negative pressure area, which is convenient for methanol to be drawn in.

[0026] This methanol leak emergency adsorption and recovery device requires the following steps to be used:

[0027] 1) When using, push the whole unit to the location of the methanol leak, and at the same time insert the grounding electrode 12 into the ground;

[0028] 2) The operator puts on protective equipment and holds the operating lever 10 to push the conical cover 9 into the methanol accumulation position;

[0029] 3) When the explosion-proof pump 5 is powered on, a negative pressure is created inside the conical cover 9, which then draws the leaked methanol into the recovery tank 2.

[0030] In summary, when in use, the system consists of a recycling bin 2, an explosion-proof pump 5, and a conical cover 9. The explosion-proof pump 5 is connected to the top of the conical cover 9 via a first anti-static pipe 13. The conical cover 9 is equipped with casters 8 on all four sides, and an operating lever 10 is rotatably mounted in the center. The operator holds the operating lever 10 to guide the conical cover 9 into the methanol accumulation area. Simultaneously, the explosion-proof pump 5 is powered on, facilitating the pumping of methanol into the recycling bin 2, thus achieving the purpose of recovering leaked methanol. The overall structure is simple, easy to operate, and convenient for widespread use. Furthermore, the support frame 7 further enhances its functionality. A cantilever mounting rod 6 is placed horizontally on one side of the top, which provides support for the first antistatic tube 13. At the same time, when the operator pushes the conical cover 9 to move, the cantilever mounting rod 6 can rotate at a certain angle with the antistatic tube 13 to facilitate the absorption of methanol. By setting three connecting wires 11 and a grounding body 12, and by electrically connecting the three connecting wires 11 to the moving platform 1, the support frame 7 and the conical cover 9 respectively, it is easy to conduct out the static electricity generated during the operation and conduct it to the ground through the grounding body 12, thereby ensuring the safety of the absorption process.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
