Description

Technical Field

[0001] The utility model relates to the technical field of hydrogenation catalyst preparation, and more specifically to a feeding device for a hydrogenation catalyst preparation kettle. Background Art

[0002] A hydrogenation catalyst refers to a catalyst used when a compound is added with hydrogen. In the process of preparing a hydrogenation catalyst using a hydrogenation catalyst preparation kettle, it is usually necessary to add some auxiliary materials to the preparation kettle in the middle of the preparation.

[0003] When adding auxiliary materials to the existing hydrogen catalyst preparation kettle, the head on the preparation kettle needs to be opened as a whole. During the opening process, not only does it need to be opened and closed manually, but it is also easy to change the preparation environment in the preparation kettle during the feeding process after the opening is fully opened, which has certain disadvantages.

[0004] Therefore, we propose a feeding device for a hydrogenation catalyst preparation kettle in view of the above problems. Utility Model Content

[0005] The utility model aims to solve the existing practical problems. Compared with the existing technology, it provides a feeding device for a hydrogenation catalyst preparation kettle, by arranging a feeding channel for feeding on the end wall on one side of the head, and adding a blocking partition that can slide inwards and outwards at the junction of the feed channel and the head, the blocking partition is moved inwards and outwards by a driving component. When it is necessary to add material, first open the cover to pre-store the material to be added in the feed channel, and then use the driving component to slide the blocking partition toward one side of the sliding cavity until the inner end of the blocking partition abuts against the groove of the feed channel. At this time, the material is introduced into the preparation kettle through the head. After the feeding is completed, the blocking partition is replaced in the feed channel. There is no need to manually open the head, and during the feeding process, it will not cause too much impact on the preparation environment in the preparation kettle.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A feeding device for a hydrogenation catalyst preparation kettle comprises a head installed up and down and a preparation kettle, a feeding port is provided on one side of the top end of the head, a feeding channel extending to the interior is embedded and installed at the feeding port, a sealing cover is rotatably installed on the top end of the feeding channel, a sliding cavity connected to the feeding port is provided on the rear end wall of the head, a blocking layer is slidably installed between the upper and lower relative inner walls of the sliding cavity, a notch matching the blocking layer is provided on the rear end wall of the feed channel, and a driving component for pulling the blocking layer inwards and outwards is fixedly installed on the rear end wall of the head.

[0008] Furthermore, the sealing head is in a conical structure that is narrow at the top and wide at the bottom, and the feed channel is inserted at the feed inlet at an angle downward.

[0009] Furthermore, guide strips are embedded and installed between the upper and lower relative inner walls of the sliding cavity, and a pair of the guide strips pass through the slots and are embedded on the relative inner walls on the inner side of the feed channel. The upper and lower end walls of the blocking partition are respectively slidably connected with the relative inner walls of the pair of guide strips. Adding a pair of guide strips is beneficial to stabilizing the guiding effect on the inner and outer sliding of the blocking partition.

[0010] Furthermore, the inner wall of the feed channel near the bottom is fixedly connected with an arc-shaped guide plate whose lower end is connected to the upper end wall of the guide bar, which is used to guide the catalyst introduced by the feed channel to prevent the catalyst from falling on the upper end of the guide bar.

[0011] Furthermore, the driving assembly includes an arc-shaped sealing sleeve fixedly mounted on the outer end wall of the head and arranged opposite to the slot of the feed channel, the arc-shaped sealing sleeve is connected to the inside of the feed channel through the slot, the arc-shaped sealing sleeve is provided with a lower end and a sliding groove opening near one end of the slot, a magnetic sliding plate is slidably mounted in the sliding groove, and the inner end wall of the sliding groove away from the slot is embedded with an electromagnetic sheet matching the magnetic sliding plate.

[0012] Furthermore, the inner end of the blocking barrier abuts against the inner wall of the feed channel, and the outer end of the blocking barrier passes through the slot and extends into the sliding cavity and is fixedly connected to the lower end wall of the magnetic sliding plate. In the initial state, the blocking barrier is blocked in the feed channel by relying on the magnetic repulsion of the electromagnetic sheet on the magnetic sliding plate. When adding material is needed, the cover is opened, and the material is introduced into the feed channel, and then the upper cover is closed, and the current direction of the electromagnetic sheet is changed. By relying on the magnetic attraction of the electromagnetic sheet on the magnetic sliding plate, the blocking barrier slides outward along a pair of guide strips toward the sliding cavity until the inner end of the blocking barrier abuts against the slot of the feed channel. At this time, the material is introduced into the preparation kettle through the head. After the feeding is completed, the current direction of the electromagnetic sheet is changed again, and the blocking barrier is re-blocked in the feed channel. There is no need to open the head, and during the adding process, it will not cause too much impact on the preparation environment in the preparation kettle.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) This solution provides a feed channel for adding materials on the end wall of one side of the head, and adds a blocking layer that can slide inwards and outwards at the junction of the feed channel and the head. The blocking layer is moved inwards and outwards by a driving component. When adding materials is required, the cover is first opened to pre-store the materials to be added in the feed channel, and then the blocking layer is slid toward the sliding cavity by the driving component until the inner end of the blocking layer abuts against the groove of the feed channel. At this time, the materials are introduced into the preparation kettle through the head. After the feeding is completed, the blocking layer is returned to the inside of the feed channel. There is no need to manually open the head, and during the feeding process, it will not cause too much impact on the preparation environment in the preparation kettle.

[0015] (2) The driving assembly in this scheme is composed of an arc-shaped sealing sleeve, a magnetic sliding plate, and an electromagnetic sheet structure. The arc-shaped sealing sleeve is sealed on the outside of the slot of the feed channel, and the internal and external movement of the sealing partition is achieved by the attraction or repulsion of the electromagnetic sheet on the magnetic sliding plate. After the material to be fed is pre-stored in the feed channel, the current direction of the electromagnetic sheet is changed, and the sealing partition slides outward toward the sliding cavity along a pair of guide strips by relying on the magnetic attraction of the electromagnetic sheet on the magnetic sliding plate, so that the lower end of the feed channel is in an open state. During the feeding process, the inside of the feed channel is in a closed and isolated state. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the utility model belong to the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] The utility model discloses a feeding device for a hydrogenation catalyst preparation kettle, please refer to Figure 1-Figure 4 , comprising a head 2 and a preparation kettle 1 installed up and down, a feeding port 201 is provided on one side of the top of the head 2, a feeding channel 3 extending to the inside of the feeding port 201 is embedded and installed, the head 2 is a tapered structure narrow at the top and wide at the bottom, and the feeding channel 3 is inserted at the feeding port 201 obliquely downward;

[0028] A sealing cover 301 is rotatably installed at the top of the feed channel 3, and a sliding cavity 202 connected to the feeding port 201 is opened on the rear end wall of the head 2. A sealing partition 5 is slidably installed between the upper and lower opposite inner walls of the sliding cavity 202, and guide strips 6 are embedded and installed between the upper and lower opposite inner walls of the sliding cavity 202. A pair of guide strips 6 pass through the groove and are embedded on the inner wall relative to the inner side of the feed channel 3. The upper and lower end walls of the sealing partition 5 are respectively slidably connected with the relative inner walls of the pair of guide strips 6. Adding a pair of guide strips 6 is beneficial to the stable guiding effect on the inner and outer sliding of the sealing partition 5.

[0029] The inner wall of the feed channel 3 near the bottom is also fixedly connected with an arc-shaped guide plate 302 whose lower end is connected to the upper end wall of the guide bar 6, which is used to guide the catalyst introduced by the feed channel 3 to prevent the catalyst from falling on the upper end of the guide bar 6.

[0030] See also Figure 3-Figure 7A notch matching the blocking barrier 5 is provided on the rear end wall of the feed channel 3, and a driving assembly for pulling the blocking barrier 5 inside and outside is fixedly installed on the rear end wall of the head 2. Specifically, the driving assembly includes an arc-shaped sealing sleeve 4 fixedly installed on the outer end wall of the head 2 and arranged in contact with the notch position of the feed channel 3. The arc-shaped sealing sleeve 4 is connected to the inside of the feed channel 3 through the notch. A sliding groove with a lower end and an opening near one end of the notch is provided inside the arc-shaped sealing sleeve 4. A magnetic sliding plate 7 whose lower end is fixedly connected to the outer end of the blocking barrier 5 is slidably installed in the sliding groove. An electromagnetic sheet 8 matching the magnetic sliding plate 7 is embedded and installed on the inner end wall of the sliding groove away from the notch.

[0031] The inner end of the blocking barrier 5 is against the inner wall of the feed channel 3, and the outer end of the blocking barrier 5 extends through the notch into the sliding cavity 202 and is fixedly connected to the lower end wall of the magnetic sliding plate 7. In the initial state, the blocking barrier 5 is blocked in the feed channel 3 by the magnetic repulsion of the electromagnetic sheet 8 on the magnetic sliding plate 7. When it is necessary to add material, the cover 301 is opened, the material is introduced into the feed channel 3, and then the upper cover 301 is closed to change the current direction of the electromagnetic sheet 8. Relying on the magnetic attraction of the electromagnetic sheet 8 on the magnetic sliding plate 7, the blocking partition 5 slides outward along a pair of guide strips 6 toward the sliding cavity 202 until the inner end of the blocking partition 5 abuts against the groove of the feed channel 3. At this time, the material is introduced into the preparation kettle 1 through the head 2. After the feeding is completed, the current direction of the electromagnetic sheet 8 is changed again, and the blocking partition 5 is re-sealed in the feed channel 3 without opening the head 2. In addition, during the feeding process, it will not cause too much impact on the preparation environment in the preparation kettle 1.

[0032] The working process and principle of the utility model are as follows:

[0033] When it is necessary to add materials, first open the cover 301 to store the materials to be added in the feed channel 3. In the initial state, the blocking layer 5 is blocked in the feed channel 3 by the magnetic repulsion of the electromagnetic sheet 8 on the magnetic sliding plate 7. After the required materials are stored in the feed channel 3, close the upper cover 301.

[0034] The current direction of the electromagnetic sheet 8 is changed, and the blocking layer 5 slides outward toward the sliding cavity 202 along the pair of guide strips 6 by the magnetic attraction of the electromagnetic sheet 8 to the magnetic sliding plate 7 until the inner end of the blocking layer 5 abuts against the notch of the feed channel 3. At this time, the material is introduced into the preparation kettle 1 through the feed channel 3 and the head 2. After the feeding is completed, the current direction of the electromagnetic sheet 8 is changed again, and the blocking layer 5 is re-blocked in the feed channel 3 without opening the head 2. In addition, during the feeding process, it will not cause too much impact on the preparation environment in the preparation kettle 1.

[0035] It should be added here that the feed channel 3 has a certain volume, and when the preparation kettle 1 is working and when the amount of material fed is large, the feeding can be completed in batches.

[0036] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
