Description

Technical Field

[0001] The utility model belongs to the technical field of catalyst reactors, and in particular relates to a reactor catalyst unloading auxiliary device. Background Art

[0002] In the chemical manufacturing industry, reactors are widely used equipment in various process flows. The process flows and reactor types are different, but reactors are generally placed on the ground, and the discharge port is mostly located above the skirt and at the bottom of the bed. The part connected to the bed is usually equipped with a manual door for isolation, and then the discharge port is sealed with a flange blind plate.

[0003] As the device runs longer, the catalyst in the reactor needs to be replaced regularly, but it is inconvenient for workers to operate because the skirt is too high or the device layout space is limited. Especially when the device is shut down and the catalyst needs to be replaced, on-site workers generally use the flange blind plate that directly opens the discharge port to discharge. Solid granular catalysts tend to flow directly from the discharge port under their own gravity, requiring workers to perform secondary bagging, transportation, cleaning and other tedious work, which is inefficient, time-consuming and labor-intensive. If the operation is improper, the catalyst may be ejected instantly, and dust may be generated, which will cause harm to the workers at the discharge port and also bring difficulties to the company's safety and environmental protection work. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a reactor catalyst unloading auxiliary device, including a top flange adapted to and detachably connected to a discharge port flange, a discharge conduit connected to the top flange and having a through cavity, and a regulating valve for controlling the discharge speed of the discharge port of the discharge conduit; the axis of the top flange is arranged at an acute angle to the axis of the discharge conduit; an opening is provided on the outer peripheral wall of the discharge conduit, and a flap for opening or closing the opening is provided at the opening.

[0005] The catalyst unloading auxiliary device for a reactor of the utility model has the beneficial effect that when the reactor device is stopped and needs to be unloaded, the top flange of the auxiliary device is installed on the unloading port flange of the reactor, a bag or other container for collecting catalyst is put on the discharge port of the unloading conduit, and the regulating valve is operated to close the discharge channel. The unloading conduit and the top flange are set at an oblique angle, that is, they are set at an oblique angle with the reactor, so that the discharge port of the unloading conduit is not set vertically downward; then the opening of the unloading conduit is opened by flipping the flap, and the operator opens the manual door isolating the unloading port of the reactor and the bed body through the opening, and quickly closes the opening, and the catalyst in the reactor bed body flows outward through the unloading port flange and the unloading conduit in turn, and the operator only needs to adjust the outflow of the catalyst by controlling the regulating valve, and the catalyst falls directly into the collection container, thus solving the problem that the catalyst is instantly ejected outward completely under the action of its own gravity, thereby ensuring the safety of the operator and the environmental protection requirements of the enterprise, while also improving the work efficiency and saving the production cost.

[0006] In some embodiments, a collar for fitting the catalyst collection container is provided on the outer peripheral wall of the discharge port of the discharge conduit, thereby facilitating fitting the catalyst collection container.

[0007] In some embodiments, one side of the flip cover is hinged on the peripheral wall of the opening, thereby facilitating opening and closing of the opening on the discharge conduit.

[0008] In some embodiments, a pin seat is provided on the discharge conduit, and a latch is used on the other side of the flip cover to engage with the pin seat to close the opening on the discharge conduit.

[0009] In some embodiments, the axis of the top flange is arranged at an angle of 45° to the axis of the discharge conduit, thereby facilitating the catalyst to flow obliquely downward under the action of gravity and also reducing the force acting on the regulating valve.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0019] Figure 1 The following schematically shows a reactor catalyst unloading auxiliary device according to an embodiment of the present utility model. Figure 1 and Figure 2 As shown, the device includes a top flange 20 adapted to and detachably connected to the discharge port flange 10, a discharge conduit 30 connected to the top flange 20 and having a through cavity, and a regulating valve for controlling the discharge speed of the discharge port 31 of the discharge conduit 30 (see Figure 1 The top flange 20 and the discharge port flange 10 are arranged at an acute angle Q; an opening 33 is provided on the outer peripheral wall of the discharge port 30, and a flap 34 is provided at the opening 33 for opening or closing the opening 33. A through cavity is formed between the inlet 32 ​​and the outlet 31 of the discharge port 30. Preferably, the top flange 20 and the discharge port flange 10 are detachably connected by bolts.

[0020] After the reactor device is stopped and safety measures are implemented, when unloading is required, the blind plate on the reactor discharge port flange 10 is first removed, the top flange 20 of the auxiliary device is installed on the reactor discharge port flange 10, a bag or other container for collecting catalyst is installed on the discharge port 31 of the discharge conduit 30, and the regulating valve is operated to close the discharge channel. The discharge conduit 30 is set at an angle to the top flange 20, that is, at an angle to the reactor, so that the discharge port 31 of the discharge conduit 30 is not set vertically downward; then the discharge conduit 30 is opened by flipping the flap 34. 0, the operator opens the manual door 11 that isolates the reactor discharge port and the bed through the opening 33, and quickly closes the opening 33. The catalyst in the reactor bed flows outward through the discharge port flange 10 and the discharge conduit 30 in turn. The operator only needs to control the regulating valve to adjust the outflow of the catalyst by the side, and directly falls into the collection container. This solves the problem that the catalyst is completely ejected outward instantly under the action of its own gravity, thereby ensuring the safety of the operator and the environmental protection requirements of the enterprise, while also improving work efficiency and saving production costs. In the process of collecting the catalyst, no external power or additional fixed action is required. After the container is full, the regulating valve is adjusted to control the discharge closure, which is convenient for replacing the container. In addition, as the material level of the solid catalyst in the discharge port flange 10 decreases and its own gravity cannot automatically discharge it, the operator can also manually discharge the remaining material by opening the opening 33, further ensuring personnel safety and environmental protection requirements.

[0021] In this embodiment, a collar 35 for fitting the catalyst collection container is provided on the outer peripheral wall of the discharge port 31 of the discharge conduit 30. Thus, it is convenient to fit the catalyst collection container. The collar 35 can be fixed by bending and welding iron wire.

[0022] like Figure 2 As shown, one side of the flip cover 34 is hinged on the outer peripheral wall of the opening 33. Thus, it is convenient to open and close the opening 33 on the discharge conduit 30. When unloading is required, the opening 33 of the discharge conduit 30 can be opened by simply flipping open the flip cover 34.

[0023] More specifically, a pin seat (not shown) is provided on the discharge conduit 30, and a latch is used on the other side of the flip cover 34 to plug into the pin seat to close the opening 33 on the discharge conduit 30. In other embodiments, the flip cover 34 and the discharge conduit 30 may be connected by other movable connection methods such as clamping, bolting, and riveting.

[0024] The axis of the top flange 20 is arranged at an angle of 45° to the axis of the discharge conduit 30. This facilitates the catalyst to flow obliquely downward under the action of gravity and also reduces the force acting on the regulating valve.

[0025] The regulating valve adopts a butterfly valve 40, which has a handle 41. The outer peripheral wall of the discharge port 31 of the discharge conduit 30 is provided with a hole for the handle 41 of the butterfly valve 40 to pass through. Therefore, it is convenient to control the flow rate of the catalyst flowing out. The opening and closing part of the butterfly valve 40 is a disc-shaped disc plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating. It is not only simple in structure, small in size, small in driving torque, easy and quick to operate, but also has good flow regulation function and closing and sealing characteristics.

[0026] The discharge port flange 10 and the discharge conduit 30 are integrally formed, and can be integrally cast, with a stable structure and convenient installation. The feed inlet 32 ​​of the discharge conduit 30 is communicated with the discharge port flange 10 .

[0027] The reactor catalyst unloading auxiliary device of the utility model is provided with an inclined unloading conduit 30 connected to the unloading port flange 10, so that the discharge port 31 of the unloading conduit 30 is not vertically downwardly arranged, thus solving the problem that the catalyst is instantly ejected outward completely under the action of its own gravity, thereby ensuring the safety of the operating personnel and the environmental protection requirements of the enterprise, and at the same time improving the work efficiency and saving the production cost.

[0028] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope of protection of the present invention.
