Abstract
Description
Technical Field
[0001] This application relates to the field of chemical production technology, and in particular to a catalyst loading device for a methanol synthesis tower. Background Technology
[0002] A methanol synthesis tower is a device used for the reaction of carbon monoxide hydrogenation to synthesize methanol. The raw materials, after pretreatment such as compression and preheating, enter the synthesis tower. Inside the tower, the gas reacts with a catalyst to produce methanol. The loading of the catalyst is a critical step in methanol production, directly affecting catalyst activity, bed resistance, and production stability.
[0003] A catalyst loading device mentioned in an existing Chinese patent (authorization announcement number: CN222989271U) can use a fan to evacuate the inside of the installation pipe and connecting pipe, thereby adsorbing impurities at the inlet through the annular pipe and the inlet to the dust storage bin, preventing dust from escaping during loading and affecting the production environment and the health of workers. Furthermore, the catalyst falls onto the metal mesh and impacts the metal mesh, causing the dust to fall downwards. The dust is then adsorbed by the collection hood, thus cleaning the dust on the surface of the catalyst and increasing the catalytic effect.
[0004] Currently, most catalysts are filtered during loading to enhance their effectiveness. However, catalyst particles vary in size, and after prolonged filtration, the catalyst may clog the filter pores. This requires workers to stop processing and clean the filter, which is inconvenient and increases workload. Utility Model Content
[0005] The purpose of this application is to solve the problem that the catalyst may clog the filter holes of the filter plate, which requires the staff to stop processing to clean the filter plate, making it inconvenient to use. This application provides a catalyst loading device for a methanol synthesis tower.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A catalyst loading device for a methanol synthesis tower includes a working box with a door hinged to its outer side. A feed pipe is installed on the top of the working box and connected to the working box. A filter plate is rotatably connected to the inner side of the working box. A discharge pipe is installed at the bottom of the working box and connected to the working box. A discharge hole is opened on the outer side of the working box, and a discharge plate is fixedly connected to the inner side of the discharge hole. An anti-clogging mechanism is provided on the outer side of the filter plate, and a dehumidification mechanism is provided on the inner side of the working box.
[0008] By adopting the above technical solution, the catalyst is put into the feed pipe and connected to the working box through the feed pipe, so that the catalyst moves to the top of the filter plate. At this time, the catalyst can be filtered through the filter plate. The filtered catalyst continues to fall downward and is discharged through the discharge pipe. Larger catalysts will fall onto the feed plate and be discharged through the feed hole. The anti-clogging mechanism reduces the risk of filter plate blockage.
[0009] Furthermore, the anti-clogging mechanism includes a connecting plate fixedly connected to the outside of the filter plate, a mounting base fixedly connected to the outside of the working box, a rotary motor fixedly connected to the top of the mounting base, the output shaft of the rotary motor passing through the working box and fixedly connected to a striking block, the output shaft of the rotary motor being rotatably connected to the working box, and the striking block contacting the connecting block when rotating.
[0010] By adopting the above technical solution, the rotary motor is started to drive the impact block to rotate. When the impact block rotates, it will hit the filter plate, causing the filter plate to vibrate and rotate. The impact force can cause the attached catalyst particles to detach from the surface of the filter plate, thereby keeping the filter pores unobstructed.
[0011] Furthermore, a sliding groove is provided on the inner side of the work box, and a slider is fixedly connected to the outer side of the connecting plate, with the slider slidably connected to the sliding groove.
[0012] By adopting the above technical solution, the slider and the groove provide guidance for the filter plate, so that the filter plate maintains the correct movement trajectory when vibrating.
[0013] Furthermore, a base plate is fixedly connected to the inner side of the work box, and springs are symmetrically fixedly connected to the top of the base plate, with the top of the springs fixedly connected to the connecting plate.
[0014] By adopting the above technical solution, the filter plate is reset by releasing the elastic potential energy of the spring, which facilitates the next vibration of the filter plate.
[0015] Furthermore, the dehumidification mechanism includes a mounting frame fixedly connected to the inside of the working box, and a dehumidification box is slidably connected to the top of the mounting frame. The inside of the dehumidification box has several through holes at equal intervals.
[0016] By adopting the above technical solution, bamboo charcoal stone is placed inside the dehumidification box, and the bamboo charcoal stone absorbs moisture from the air through its porous structure.
[0017] Furthermore, the outer side of the mounting bracket is symmetrically connected to a rotating shaft, and the outer side of the rotating shaft is fixedly connected to an abutment plate, which is slidably disposed with the dehumidification box.
[0018] By adopting the above technical solution, the dehumidifier can be limited by rotating the contact plate to the outside of the dehumidifier box.
[0019] In summary, this application includes at least one of the following beneficial effects;
[0020] 1. In this application, when the filter plate is filtering, the rotating motor is started to drive the impact block to abut against the filter plate. The impact force can cause the attached catalyst particles to detach from the surface of the filter plate, thereby keeping the filter holes unobstructed, ensuring stable filtration efficiency, reducing the inconvenience of manual cleaning during downtime, thereby reducing workload and improving work efficiency.
[0021] 2. In this application, when dehumidifying the working chamber, bamboo charcoal stone is placed inside the dehumidification chamber. The bamboo charcoal stone absorbs moisture from the air through its porous structure, and the pores allow air inside the working chamber to enter the dehumidification chamber more smoothly, thereby reducing the impact of moisture on the catalyst.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0029] This application discloses a catalyst loading device for a methanol synthesis tower.
[0030] Reference Figure 1 and Figure 2A catalyst loading device for a methanol synthesis tower includes a working box 1, a door 2 hinged to the outside of the working box 1, a feed pipe 3 installed on the top of the working box 1 and connected to the working box 1, a filter plate 4 rotatably connected to the inside of the working box 1, a discharge pipe 5 installed at the bottom of the working box 1 and connected to the working box 1, a discharge hole 6 opened on the outside of the working box 1, a discharge plate 7 fixedly connected to the inside of the discharge hole 6, an anti-clogging mechanism on the outside of the filter plate 4, and a dehumidification mechanism on the inside of the working box 1.
[0031] When loading the catalyst, the catalyst is first put into the feed pipe 3, which is connected to the working box 1, so that the catalyst moves to the top of the filter plate 4. At this time, the catalyst can be filtered through the filter plate 4. The filtered catalyst continues to fall downward and is discharged through the discharge pipe 5. Larger catalysts will fall onto the feed plate 7 and be discharged through the feed hole 6. The anti-clogging mechanism facilitates the vibration of the filter plate 4, reducing the risk of filter plate 4 clogging and reducing the inconvenience of manual cleaning.
[0032] Reference Figure 2 and Figure 3 The anti-clogging mechanism includes a connecting plate 8 fixedly connected to the outside of the filter plate 4, a mounting base 9 fixedly connected to the outside of the working box 1, a rotary motor 10 fixedly connected to the top of the mounting base 9, the output shaft of the rotary motor 10 passing through the working box 1 and fixedly connected to a striking block 11, the output shaft of the rotary motor 10 being rotatably connected to the working box 1, and the striking block 11 contacting the connecting block when rotating.
[0033] The inner side of the work box 1 is provided with a slide groove 19, and the outer side of the connecting plate 8 is fixedly connected with a slider, which is slidably connected to the slide groove 19.
[0034] In addition, a base plate 12 is fixedly connected to the inside of the work box 1, and springs 13 are fixedly connected symmetrically to the top of the base plate 12. The top of the springs 13 is fixedly connected to the connecting plate 8.
[0035] When the filter plate 4 is filtering, the rotating motor 10 drives the impact block 11 to rotate. When the impact block 11 rotates, it will contact the filter plate 4, causing the filter plate 4 to vibrate and rotate. The impact force can cause the attached catalyst particles to detach from the surface of the filter plate, thereby keeping the filter holes unobstructed, ensuring stable filtration efficiency, reducing the inconvenience of manual cleaning during downtime, thereby reducing workload and improving work efficiency.
[0036] When the striking block 11 contacts the connecting block, the connecting block compresses the spring 13 downwards. After the spring 13 is compressed, it generates elastic potential energy. After the striking block 11 moves away from the connecting plate 8, the elastic potential energy of the spring 13 is released, causing the filter plate 4 to reset, thus facilitating the next vibration of the filter plate 4.
[0037] When the filter plate 4 vibrates, the slider and the groove 19 provide guidance for the filter plate 4, so that the filter plate 4 maintains the correct motion trajectory during vibration.
[0038] Reference Figure 2 and Figure 4 The dehumidification mechanism includes a mounting bracket 14 fixedly connected to the inside of the working box 1. A dehumidification box 15 is slidably connected to the top of the mounting bracket 14. Several through holes 16 are equidistantly opened on the inside of the dehumidification box 15.
[0039] Among them, the outer side of the mounting bracket 14 is symmetrically connected to the rotating shaft 17, and the outer side of the rotating shaft 17 is fixedly connected to the contact plate 18, which is slidably arranged with the dehumidification box 15.
[0040] When dehumidifying the working chamber 1, first open the chamber door 2 and place the dehumidification chamber 15 on top of the mounting bracket 14. Then, place bamboo charcoal stone inside the dehumidification chamber 15. The bamboo charcoal stone absorbs moisture from the air through its porous structure. The through hole 16 allows the air inside the working chamber 1 to enter the dehumidification chamber 15 more smoothly, thereby reducing the impact of moisture on the catalyst.
[0041] When limiting the dehumidification box 15, the dehumidification box 15 can be limited by rotating the contact plate 18 to the outside of the dehumidification box 15, thereby improving the stability of the dehumidification box 15 during operation.
[0042] Working principle: The catalyst is put into the feed pipe 3, which is connected to the working box 1, so that the catalyst moves to the top of the filter plate 4. At this time, the catalyst can be filtered through the filter plate 4. The filtered catalyst continues to fall downward and is discharged through the discharge pipe 5. Larger catalysts will fall onto the feed plate 7 and be discharged through the feed hole 6. The rotating motor 10 drives the impact block 11 to rotate. When the impact block 11 rotates, it will abut against the filter plate 4, causing the filter plate 4 to vibrate and rotate. The impact force can make the attached catalyst particles detach from the surface of the filter plate, thereby keeping the filter holes unobstructed.
