Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for stirring reactors, and more specifically, to a protective structure for preventing accidental contact during stirring of a reactor. Background Technology

[0002] Currently, in laboratories and pilot plants, the stirring components of reactors are partially exposed to the outside environment (specifically, the stirring shaft is located inside the reactor and is equipped with stirring rods, while the motor driving the stirring shaft is located on the reactor mounting frame rather than on the reactor lid (as per the instruction manual). Figure 1 As shown in the diagram, this necessitates an external roller connecting the motor and the stirring shaft outside the reactor. The external roller must be sized to fit the stirring shaft, thus not occupying space on the reactor lid and not obstructing any pipes such as condenser pipes installed on the lid. However, during operation, the unprotected external roller rotates at high speed. If an operator accidentally comes into contact with the rotating roller, fingers, arms, or other body parts could be caught, causing serious injury. This risk is particularly high in workplaces with inadequate safety measures and where operating procedures are not strictly followed.

[0003] Meanwhile, because the external rod lacks external protection, it is prone to damage. Damage can trigger a series of chain reactions, leading to mechanical equipment failure. Equipment failure and downtime not only affect production schedules and cause production losses, but also increase maintenance costs and time costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a protective structure to prevent accidental contact for stirring in a reaction vessel.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An anti-accidental contact protection structure for stirring a reactor includes a screw, a knob, a semi-circular shell, a mounting plate, a through hole, a nut, a semi-circular hole, a mating assembly, and a magnetic composite dust suppression assembly.

[0007] The screws are symmetrically distributed on the reactor mounting frame and are threadedly connected to the top cover of the reactor mounting frame.

[0008] The knob is connected to the upper end of the screw;

[0009] Two open semi-circular shells are symmetrically welded with mounting plates, and the mounting plates are provided with through holes that allow screws to pass through.

[0010] The nut is threadedly connected to the screw.

[0011] The semi-circular hole is formed on the bottom surface of the semi-circular shell;

[0012] The two semi-circular shells are accurately spliced ​​together by a fitting assembly, and after splicing, the two semi-circular holes form a circular hole that matches the size of the external roller.

[0013] The magnetic composite dust suppression component is movably installed inside the semi-circular shell.

[0014] Furthermore, the mating assembly includes a connecting plate, a plug block, and a slot.

[0015] The connecting plates are symmetrically welded onto each semi-circular shell.

[0018] Furthermore, the magnetic composite dust suppression component includes an arc-shaped plate, arc-shaped through holes, a dust suppression mesh, and neodymium iron boron permanent magnets.

[0019] The arc-shaped plate is welded to the middle area of ​​the inner wall of the semi-circular shell and fits against the inner wall of the semi-circular shell;

[0020] An arc-shaped through hole is formed on the arc-shaped plate;

[0021] The dust suppression net is inserted into the arc-shaped through hole and passes through the arc-shaped through hole to contact the bottom surface of the semi-circular shell;

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] Compared to existing technologies, this application protects the mixing equipment by wrapping two spliced ​​semi-circular shells around the outer side of the external roller between the motor and the mixing shaft. This reduces safety hazards caused by improper operation by workers, improves protection measures, and reduces the failure rate of the mixing equipment. In addition, the magnetic composite dust suppression component can effectively adhere and collect the dust generated during motor operation, thereby significantly reducing the amount of dust spilled into the surrounding environment.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0035] like Figures 1 to 4 As shown, a protective structure for preventing accidental contact during stirring in a reaction vessel includes a screw 1, a knob 2, a semi-circular shell 3, a mounting plate 4, a through hole 5, a nut 6, a semi-circular hole 301, a mating assembly, and a magnetic composite dust suppression assembly.

[0036] The screws 1 are symmetrically distributed on the reactor mounting frame and are threadedly connected to the top cover of the reactor mounting frame;

[0037] Knob 2 is connected to the upper end of screw 1;

[0038] Two open semi-circular shells 3 are symmetrically welded with mounting plates 4, and the mounting plates 4 are provided with through holes 5 that allow the screws 1 to pass through and correspond one-to-one.

[0039] Nut 6 is threadedly connected to screw 1 (specifically, a flat washer is added between nut 6 and mounting plate 4 to distribute pressure and protect the contact surface of mounting plate 4).

[0040] A semi-circular hole 301 is formed on the bottom surface of the semi-circular shell 3;

[0041] The two semi-circular shells 3 are accurately spliced ​​together by the interlocking assembly, and after splicing, the two semi-circular holes 301 form a circular hole that matches the size of the external roller.

[0042] The magnetic composite dust suppression component is movably installed inside the semi-circular shell 3.

[0043] Specific implementation of the embodiments of this utility model, such as Figure 3 As shown, the mating assembly includes a connecting plate 7, a plug block 8, and a slot.

[0044] The connecting plates 7 are symmetrically welded onto each of the semi-circular shells 3;

[0045] The insert 8 is mounted on the connecting plate 7 of one of the semi-circular shells 3;

[0046] The slot is located on the connecting plate 7 of another semi-circular shell 3 (the slot is not shown in the figure), and the slot mates with the insert block 8.

[0047] Specific implementation of the embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the magnetic composite dust suppression component includes an arc-shaped plate 9, arc-shaped through holes 10, and a dust suppression net.

[0048] The arc-shaped plate 9 is welded to the middle area of ​​the inner wall of the semi-circular shell 3 and fits against the inner wall of the semi-circular shell 3;

[0049] An arc-shaped through hole 10 is formed on the arc-shaped plate 9;

[0050] The dust suppression net is inserted into the arc-shaped through hole 10 and passes through the arc-shaped through hole 10 to contact the bottom surface of the semi-circular shell 3.

[0051] To improve the sealing between the top of the circular shell and the top cover of the reactor mounting frame after the circular shell is installed, the above embodiment is further optimized by providing a half-seal ring on the upper cross section of the semi-circular shell 3, and the two semi-circular shells 3 are assembled to form a complete seal ring.

[0052] To extend the service life of the semi-circular shell 3, the above embodiment is further optimized by providing a polyurethane shell (not shown in the figure) on the outer side of the semi-circular shell 3.

[0053] The working process of this utility model is as follows:

[0054] First, hold the two semi-circular shells 3 and approach them from both sides of the outer roller towards the center. At this time, the design of the insert block 8 and the slot allows the two semi-circular shells 3 to be accurately aligned. After alignment, the outer roller is placed in the circular hole without contacting the circular hole. Then, align the through holes 5 on the two mounting plates 4 with the two screws 1 and pass them through so that the upper section of the semi-circular shell 3 is in contact with the inner side of the top cover of the reactor mounting frame. Then, use the nut 6 to limit the position of the circular shell. During the process of fixing the circular shell, the two semi-circular shells 3 are not easy to separate due to magnetic adsorption. After the limit is completed, the two semi-circular shells 3 are not easy to separate under the dual limitation of screws 1 and magnetic adsorption. At this time, a cover can be formed to protect the outer roller. Afterwards, the staff will not directly contact the high-speed rotating outer roller when adding materials or performing other operations, thus significantly reducing the safety risk. At the same time, the circular shell can reduce the probability of damage to the outer roller, thus making the equipment less likely to malfunction or stop.

[0055] While the outer roller is being protected by wrapping it, the motor operation generates some dust (the dust comes from two sources: 1. metal particles generated by long-term friction in the bearing raceway or rolling elements, resulting in black metal particles in the grease; 2. carbonization of the grease due to high temperature or oxidation, forming black powdery residue, which mixes with metal wear particles to form a "black powder" phenomenon). At this time, these iron filings fall into the cylindrical shell and are adsorbed onto the dust suppression net with embedded neodymium iron boron permanent magnets (the dust will adhere to the surface of the dust suppression net under the influence of the high-speed rotating wind), thus significantly reducing the amount of dust overflow. When it is necessary to clean the attached dust, simply control the motor to turn off the power first, then loosen the nut 6 to remove and separate the semi-circular shell 3 to easily remove the dust suppression net for cleaning (the iron filings can be wiped off with a magnetic rod). The dust suppression net will not shift inside the semi-circular shell 3 due to the limitation of the arc-shaped through hole 10 and is easy to disassemble and maintain. Therefore, in addition to protecting the outer roller, it can also effectively reduce the amount of dust overflow generated by the motor during the stirring process.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
