Description

Technical Field

[0001] The utility model belongs to the technical field related to the production of nickel-based catalysts, and particularly relates to a shaping die for the production of nickel-based catalysts. Background Technique

[0002] Nickel-based catalysts generally refer to Raney nickel, also known as Raney nickel, which is a solid heterogeneous catalyst composed of fine grains of nickel-aluminum alloy with a porous structure. It was first used as a catalyst in the hydrogenation process of vegetable oils. However, nickel-based catalysts have micropores of different sizes. Raney nickel appears as fine gray powder on the surface, but from a microscopic perspective, each tiny particle in the powder is a three-dimensional porous structure. This porous structure greatly increases its surface area, and the extremely large surface area brings high catalytic activity. This makes Raney nickel widely used as a heterogeneous catalyst in organic synthesis and hydrogenation reactions in industrial production. During the production process, it is necessary to support the nickel-based catalyst powder into granular form to maintain stability and facilitate transportation and other uses, which requires the cooperation of relevant shaping dies. However, the relevant shaping dies still have the following disadvantages in actual use:

[0003] 1. During the shaping granulation process of nickel-based catalysts, it is necessary to quickly carry out granulation operations. However, for powder granulation, it can only rely on strong pressure for pressing, and the conventional granulation method for liquid materials cannot meet the requirements.

[0004] 2. Secondly, during the granulation and forming process, it is necessary to intermittently supplement raw materials. After granulation, the next batch of raw materials needs to be quickly supplemented, and a stable processing efficiency needs to be maintained.

[0005] 3. Finally, granulation usually requires the assistance of a shaping die, but it is different from the conventional fluid extrusion type shaping granulation. After the nickel-based catalyst is formed in the die, it is not convenient to quickly export, which will affect the processing efficiency. Content of the Utility Model

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Please refer to Figure 1-7 As shown, the present invention is a shaping die for the production of nickel-based catalysts, including a workbench 1, a pressing plate 2, a preparation frame 3, a main body of the shaping die 5, a surrounding frame 6 and an insertion plate 7. Two groups of limit rods 105 are symmetrically fixed at the upper end of the workbench 1, and a pressing plate 2 is slidably sleeved outside the two groups of limit rods 105. Pressing rods 201 distributed in a rectangular array are fixed on the bottom surface of the pressing plate 2;

[0034] First of all, the workbench 1 serves as the main working place. The position of the pressing plate 2 is restricted by the limit rods 105 above it, and it remains stable during the lifting and lowering process of the pressing plate 2, so that the pressing rods 201 at the bottom of the pressing plate 2 can accurately align with the shaping groove 501 to perform a pressing and shaping process on the powder in the shaping groove 501;

[0035] A through groove 106 is opened at the center of the upper surface of the workbench 1, and a surrounding frame 6 is fixed on the upper surface of the workbench 1 outside the through groove 106. A main body of the shaping die 5 is fixed inside the upper part of the surrounding frame 6, and shaping grooves 501 corresponding to the number of pressing rods 201 are opened in the main body of the shaping die 5;

[0036] The through groove 106 is used to assist in discharging the formed nickel-based catalyst particles. The surrounding frame 6 is used to assist in fixing the main body of the shaping die 5 and make the main body of the shaping die 5 have a certain height. Shaping grooves 501 are arranged in the main body of the shaping die 5 for filling nickel-based catalyst powder for granulation and shaping;

[0038] The preparation frame 3 is used to assist in the feeding operation. The nickel-based catalyst powder is placed on the bearing platform 301. With the scraping of the scraper 8, the nickel-based catalyst powder enters the shaping groove 501 in the shaping die body 5 until the shaping groove 501 is filled, realizing a rapid feeding operation;

[0039] A plug board 7 is inserted into the surrounding frame 6 in a through-hole and movable manner, and a square groove 702 is also arranged in the plug board 7; the plug board 7 can move within the surrounding frame 6 to close the bottom of the shaping die body 5. When the plug board 7 is moved so that the square groove 702 is located below the shaping die body 5, the shaped nickel-based catalyst particles can be discharged.

[0040] Symmetrically distributed supporting legs 101 are fixed to the bottom of the workbench 1, and symmetrically distributed vertical plates 102 are also fixed to the upper end of the workbench 1. A reinforcing rib 1021 is fixed between the side of the vertical plate 102 away from the through groove 106 and the upper end surface of the workbench 1. A cross plate 103 is fixed to the two vertical plates 102 together. The cross plate 103 is located above the pressing plate 2, and a hydraulic cylinder 104 is fixed to the top surface of the cross plate 103, and the telescopic end of the hydraulic cylinder 104 penetrates the cross plate 103 and is fixed to the top surface of the pressing plate 2;

[0041] The pressing plate 2 is located above the shaping die body 5, and the pressing rod 201 is located above the forming groove, and the number of the pressing rods 201 is equal to the number of the forming grooves. A forming groove is vertically corresponding to each pressing rod 201 below;

[0042] The workbench 1 is stably supported by the supporting legs 101 and has a certain distance from the ground. The cross plate 103 is installed on the workbench 1 through the vertical plates 102, and the hydraulic cylinder 104 is installed on the cross plate 103. The hydraulic cylinder 104 can drive the pressing plate 2 to lift and lower, so as to make the pressing rod 201 lift and lower, and control whether the pressing rod 201 enters the shaping groove 501. After the pressing rod 201 enters the shaping groove 501, the nickel-based catalyst powder is pressed to form granular materials, realizing the pressing and forming operation.

[0043] The adjacent ends of the two bearing platforms 301 are fixed to the outer wall of the shaping die body 5, and the upper surface of the bearing platform 301 is flush with the upper surface of the shaping die body 5. The upper end of the preparation frame 3 is higher than the shaping die body 5;

[0044] The preparation frame 3 is slightly higher than the shaping die body 5, so that a certain amount of nickel-based catalyst powder material can be stored on the bearing platform 301, which is convenient for subsequent feeding use.

[0045] Supporting plates 302 are fixed to the bottom of the bearing platform 301, and the bottom surface of the supporting plates 302 is fixed to the upper surface of the workbench 1; used to enhance the structural strength of the bearing platform 301.

[0046] The upper surface of the plug board 7 contacts the lower surface of the shaping die main body 5, and the length of the plug board 7 is greater than twice the length of the shaping die main body 5. A limiting plate 703 is fixed at one end of the plug board 7 close to the square groove 702, a handle 701 is fixed at the other end of the plug board 7, and limiting strips 704 are fixed on both sides of the plug board 7. Limiting grooves matching the limiting strips 704 are formed on two opposite inner walls of the surrounding frame 6. The plug board 7 is slidably inserted into the surrounding frame 6 through the limiting strips 704 inserted into the limiting grooves;

[0047] When the plug board 7 contacts the lower surface of the shaping die main body 5, the lower end of the shaping groove 501 is blocked, which is convenient for use during pressing and shaping. When discharging is required, the plug board 7 is pulled by the handle 701 to make the square groove 702 located below the shaping die main body 5, and then the pressing rod 201 is moved downward to extrude the nickel-based catalyst particles in the shaping groove 501 to achieve the discharging operation.

[0048] The upper part of the shaping groove 501 is in an inverted frustum shape structure, the lower part of the shaping groove 501 is in a cylindrical groove structure, and the minimum diameter of the shaping groove 501 is equal to the diameter of the pressing rod 201; it is convenient for the pressing rod 201 to enter the shaping groove 501 better and more accurately. A collection box 4 is arranged below the through groove 106; it is used to collect the formed nickel-based catalyst particles.

[0049] The specific working principle of the present utility model is as follows: First, the powder raw material of the nickel-based catalyst is replenished. A certain amount of nickel-based catalyst powder is directly poured onto the bearing platform 301 and the shaping die main body 5, and then the scraper 8 is used to scrape back and forth several times, which can make the shaping groove 501 filled with nickel-based catalyst powder to quickly replenish the raw material. Subsequently, the hydraulic cylinder 104 drives the pressing plate 2 to lift and lower, so as to make the pressing rod 201 lift and lower, and control whether the pressing rod 201 enters the shaping groove 501. After the pressing rod 201 enters the shaping groove 501, the nickel-based catalyst powder is pressed to form granular materials. During this process, the plug board 7 contacts the lower surface of the shaping die main body 5 to block the lower end of the shaping groove 501 to complete the pressing. After shaping, the plug board 7 is pulled by the handle 701 to make the square groove 702 located below the shaping die main body 5, and then the pressing rod 201 is driven to move downward to extrude the nickel-based catalyst particles in the shaping groove 501 into the collection box 4 for collection, completing the shaping operation of one batch.

[0050] The above is only the preferred embodiment of the present utility model, which does not limit the present utility model. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present utility model.
