Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically a timed and weighted catalyst feeding device. Background Technology

[0002] Catalysts play a crucial role in dye production. Problems in either the amount added or the timing of their addition can lead to the failure of the entire reaction, resulting in significant economic and time losses. Strictly adhering to the required order of material addition is essential, as different sequences can trigger different chemical reactions, leading to variations in product quality. For example, in the synthesis of disperse dyes, the dispersant and a portion of the solvent are typically added first, stirred thoroughly, followed by the dye intermediate, and finally the oxidant for oxidation. Reversing the order may cause the dye intermediate to polymerize without sufficient dispersion, forming large aggregates that negatively impact the dye's dispersibility and dyeing properties.

[0003] Most existing catalyst devices directly add catalysts to the reactor. However, one-time addition may lead to excessively high local material concentrations, excessively violent reactions, and a large amount of heat that cannot be dissipated in time, causing local overheating or even explosions and other safety accidents. To address this, we propose a timed and weighted catalyst addition device. Utility Model Content

[0004] The purpose of this invention is to provide a timed and weighted catalyst addition device to solve the problem mentioned in the background art that a single addition may lead to excessively high local material concentration, excessively violent reaction, and a large amount of heat that cannot be dissipated in time, causing local overheating or even explosions and other safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a timed and weight-based catalyst dosing device, comprising: a catalytic reactor; Also includes: A mounting bracket is located at the bottom of the catalytic reactor and is used to fix the catalytic reactor. The reaction vessel is located below the fixed frame and is used to stir and mix dyes; The feeding component is located at the bottom of the fixed frame. The feeding component is used to disperse the catalyst and add the catalyst quantitatively to the reactor. The feeding component includes a movable tube. Multiple differentiation tubes are fixedly connected to the bottom of the movable tube. The multiple differentiation tubes are arranged in a ring array about the central axis of the movable tube. A fixed ring is fixedly connected between the bottom ends of each differentiation tube.

[0006] The bottom of the catalytic reactor is equipped with an output pipe, and the top of the output pipe is equipped with a flow regulating valve. The output pipe is connected to the movable pipe.

[0007] The reactor is equipped with a lid at the top, which is fixedly connected to a movable tube. The movable tube is located at the central axis of the lid, and a flow meter is installed at the bottom of the movable tube. The flow meter is electrically connected to a flow regulating valve.

[0008] Among them, multiple differentiation tubes are fixedly connected by fixing rings, and the fixing rings are fixedly connected to the vessel lid.

[0009] The frame has limit plates fixedly connected to both sides, and mounting plates are fixedly connected to the rear sides of the two limit plates.

[0010] The movable tube has a set of movable frames on both sides, with two movable frames in each set. A movable shaft connects the two movable frames. The outer wall of the limiting plate has a sliding groove, and the internal dimensions of the sliding groove match the external dimensions of the movable shaft.

[0011] A reset spring is provided on the outside of the output tube, and the bottom end of the reset spring is fixedly connected to the movable tube.

[0012] This utility model has at least the following beneficial effects: Two movable shafts move in opposite directions inside the chute, causing the two sets of movable frames connected to the movable shafts to separate in a cross shape. This drives the movable tube to move along the output tube. By raising and lowering the movable tube, the entire kettle lid is lifted. Subsequently, the operator can add various dyes into the reactor. The combination of the kettle lid and the feeding component facilitates the rapid addition of dyes while strictly adhering to the process requirements for adding catalysts. Furthermore, multiple dispersing tubes disperse the dispersant in the solution, facilitating better control of the reduction reaction conditions and reaction rate. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figures 1 to 5 This utility model provides a technical solution: a timed and weighted catalyst addition device, comprising: a catalyst reactor 001; Also includes: Fixing frame 002 is located at the bottom of catalytic reactor 001 and is used to fix catalytic reactor 001. Reactor 003 is located below the fixed frame 002 and is used to stir and mix dyes. Feeding component 004 is located at the bottom of fixed frame 002. Feeding component 004 is used to disperse catalyst and quantitatively add catalyst to reaction vessel 003. Feeding component 004 includes movable tube 401. Multiple differentiation tubes 402 are fixedly connected to the bottom end of movable tube 401. Multiple differentiation tubes 402 are arranged in a ring array about the central axis of movable tube 401. Fixed rings 403 are fixedly connected between the bottom ends of each differentiation tube 402.

[0017] Both sides of the movable tube 401 have a set of movable frames 130. Each set of movable frames 130 has two frames. The two movable frames 130 are movably connected by a movable shaft 140. The outer wall of the limiting plate 210 has a sliding groove 150. The internal dimensions of the sliding groove 150 match the external dimensions of the movable shaft 140.

[0018] In this process, the operator can install cylinders at the rear end of the two movable shafts 140, start the cylinders, and drive the two movable shafts 140 to move in opposite directions inside the slide 150. This causes the two sets of movable frames 130 connected to the movable shafts 140 to separate in a cross shape. The two sets of movable frames 130 simultaneously drive the movable tube 401 to move along the output tube 110. By lifting the movable tube 401, the entire lid 310 is lifted. Subsequently, the operator can put various dyes into the reactor 003. The lid 310 is combined with the feeding component 004 to ensure that the reactor 003 is completely closed before feeding materials into the reactor 003.

[0019] The bottom of the catalytic reactor 001 is equipped with an output pipe 110, and the top of the output pipe 110 is equipped with a flow regulating valve 120. The output pipe 110 is connected to the movable pipe 401.

[0020] The top of the reactor 003 is provided with a lid 310, which is fixedly connected to the movable tube 401. The movable tube 401 is located at the central axis of the lid 310. A flow meter 410 is installed at the bottom of the movable tube 401, and the flow meter 410 is electrically connected to the flow regulating valve 120.

[0021] The flow meter 410 and flow regulating valve 120 are connected in series to the SIS and DCS systems. During production, the SIS system of this device can be activated to achieve automatic and quantitative addition of catalyst at any time, avoiding human risks such as forgetting, under-addition, over-addition, or incorrect addition. This enables more demanding automated operation and lean production.

[0022] A fixing ring 403 is fixedly connected between multiple differentiation tubes 402, and the fixing ring 403 is fixedly connected to the kettle cover 310.

[0023] Multiple differentiation tubes 402 are arranged in a ring around the vessel lid 310. The catalyst enters the multiple differentiation tubes 402 through the output tube 110 and the active tube 401 to disperse the dispersant in the solution, which facilitates better control of the reduction reaction conditions and reaction rate.

[0024] Both sides of the fixed frame 002 are fixedly connected to limit plates 210, and the rear side of the two limit plates 210 is fixedly connected to the mounting plate 220.

[0025] The operator can fix the mounting plate 220 to other support surfaces by passing screws through the mounting plate 220, thereby fixing the two limiting plates 210, so that the fixing frame 002 can be used stably and support the entire catalytic reactor 001.

[0026] Example 2 like Figure 4 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a reset spring 160 is provided on the outside of the output tube 110, and the bottom end of the reset spring 160 is fixedly connected to the movable tube 401.

[0027] The reset spring 160 is designed to provide a downward elastic force to the movable tube 401, so that the lid 310 can be pressed tightly against the reactor 003, thus preventing the dye from splashing to the outside during feeding and dye production.
