Description

Technical Field

[0001] This utility model belongs to the field of catalyst material processing technology, and in particular relates to a high-efficiency catalyst material classification device. Background Technology

[0002] Catalysts are substances that can accelerate the reaction rate during a chemical reaction but do not undergo permanent changes after the reaction. Catalysts accelerate the reaction by providing an alternative reaction pathway and lowering the activation energy of the reaction. Catalysts can be solid, liquid, or gaseous, with solid catalysts being widely used in industrial fields, especially in petroleum refining, fertilizer production, and environmental protection.

[0003] In the prior art, Chinese patent publication number "CN218014177U" discloses a finished particle grading device for catalyst additives. The device support is U-shaped, and a shaking mechanism is provided on the bottom side wall of the device support. The shaking mechanism includes a support platform and a shaking rod. A sorting mechanism is provided in the inner cavity of the device support. By setting the sorting mechanism, when using the device, the finished particle material is introduced into the sorting channel at the top of the inner cavity of the sorting body through the feeding channel. Since the sorting body is placed in an inclined state with the left side lower and the right side higher, the finished particle material moves from right to left under the action of its own gravity. During the movement, the finished particle material is sorted into four sizes by the first screening plate, the second screening plate and the third screening plate, and then discharged and collected through the four sets of discharge channels. The above operation can be continuously carried out to improve the processing efficiency of the finished particle material of the device.

[0004] However, the above-mentioned device still has the following problems in the implementation process: In the above application, after the material is screened, it needs to be discharged through the discharge channel. However, the discharge channel is designed to be open, and the whole device uses a vibrating structure and an inclined structure for screening. This causes the material to fall due to vibration and inclination during the screening process. This phenomenon not only affects the screening effect, but may also lead to material loss, thereby reducing the working efficiency of the equipment and the utilization rate of the material.

[0005] To address these issues, we provide a high-efficiency catalyst material classification device. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency catalyst material classification device. By combining the discharge component and the efficiency-enhancing component, it solves the problem in the existing catalyst additive finished particle classification device that causes some material to fall through the discharge channel during material screening, resulting in material loss.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a high-efficiency catalyst material classification device, comprising a frame, a classification box movably connected to the inner cavity of the frame, and a discharge port on one side of the classification box; a discharge assembly is provided on one side of the frame, the discharge assembly including sliding rods fixedly connected to both sides of the device, a receiving block slidably connected to the surface of the sliding rods, a sealing plate fixedly connected to one side of the receiving block, and extrusion blocks fixedly connected to both sides of the top of the discharge port, the discharge assembly being used to automatically discharge the classified catalyst material; an efficiency enhancement assembly is provided on the top of the classification box, the efficiency enhancement assembly including a fan fixedly connected to one side of the top of the frame, an air pipe connected to the output end of the fan, and a conical guide hood fixedly connected to the top of the classification box, one end of the air pipe being connected to the top of the conical guide hood, the efficiency enhancement assembly being used to evenly diffuse the airflow downwards.

[0009] The present invention is further configured such that a cylinder is movably connected to one side of the bottom of the equipment frame, and the free end of the cylinder is movably connected to one side of the bottom of the grading box.

[0010] The present invention is further configured such that a sieve plate is fixedly connected to the inner cavity of the grading box, and the number of the sieve plates is three.

[0011] The present invention is further configured such that a flow guide frame is fixedly connected to one side of the equipment frame, and slide bars are fixedly connected to both sides of the inner cavity of the flow guide frame. Guide bars are fixedly connected to both sides of the bottom of the sealing plate, and the bottom of the guide bars is slidably connected to the surface of the slide bars.

[0012] The present invention is further configured such that a feed inlet is provided on one side of the top of the grading box, a discharge outlet is provided at the bottom of the grading box, and a valve is installed on the surface of the discharge outlet.

[0013] The present invention is further configured such that limiting rods are fixedly connected to both sides of the equipment frame, and the surface of the limiting rods is slidably connected to one side of the inner cavity of the block being resisted.

[0014] The present invention is further configured such that a spring is sleeved on the surface of the slide bar, and one end of the spring is fixedly connected to one side of the block being resisted.

[0015] The present invention has the following beneficial effects.

[0016] This invention, by setting up a discharge assembly and adopting a linkage structure of sliding rod, supporting block, sealing plate, and extrusion block, realizes the automatic switching between screening and discharge states of the grading box. During screening, the spring pushes the supporting block to make the sealing plate tightly lock the discharge port, ensuring sealing. After screening, the cylinder drives the grading box to rotate, and the extrusion block presses the supporting block to drive the sealing plate away from the discharge port, realizing automatic discharge. This design cleverly uses the movement of the equipment itself as a power source, without the need for an additional drive device. It not only solves the problem of material leakage in traditional vibrating screens, but also ensures the precise opening and closing of the discharge port through mechanical linkage, significantly improving the material recovery rate and equipment reliability.

[0017] This invention utilizes the synergistic effect of the fan, air pipe, and conical guide hood in the efficiency-enhancing component to evenly diffuse airflow into the inner cavity of the classifier. On the one hand, this accelerates the dispersion and falling of materials, preventing particle accumulation and clogging of the screen. On the other hand, the airflow assists fine particles in penetrating the screen holes, improving classification efficiency and accuracy. Furthermore, the design of the conical guide hood optimizes the uniformity of airflow distribution, further shortening the classification time. It is suitable for the efficient separation of catalyst materials of different particle sizes.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figures 1-5 This utility model is a high-efficiency catalyst material classification device, including a frame 1, a classification box 2 movably connected to the inner cavity of the frame 1, and a discharge port 3 on one side of the classification box 2; three discharge ports 3 are opened on one side of the classification box 2, corresponding to one side of three screening plates 12. A discharge assembly is provided on one side of the frame 1, the discharge assembly including a slide rod 4 fixedly connected to both sides of the device, a limit block fixedly connected to one end of the slide rod 4 to prevent the abutment block 5 from separating from the surface of the slide rod 4, the abutment block 5 slidably connected to the surface of the slide rod 4, one side of the abutment block 5 contacts one side of the extrusion block 7, and the bottom is fixed to one side of the sealing plate 6 so that when the extrusion block 7 rotates, it drives the sealing plate 6 to separate from the inner cavity of the discharge port 3. The sealing plate 6 is fixedly connected to one side of the abutment block 5, one side of the sealing plate 6 fits against one side of the discharge port 3 and does not extend completely. The material is directed into the discharge port 3 to prevent the sealing plate 6 from moving when the classifier 2 rotates. Extrusion blocks 7 are fixedly connected to both sides of the top of the discharge port 3. These components are used to automatically discharge the classified catalyst material. An efficiency-enhancing component is installed on the top of the classifier 2. This component includes a blower 8 fixedly connected to one side of the top of the equipment frame 1. The blower 8 is an existing structure that can blow air into the classifier 2 using an air pipe 9. The air pipe 9 is connected to the output end of the blower 8. A conical guide hood 10 is fixedly connected to the top of the classifier 2. After the airflow is reflected by the conical surface, it forms a uniformly downward-spreading turbulent field, covering all the sieve plates 12. This converts the straight airflow into a rotating airflow, enhancing the penetration of the sieve plates 12. One end of the air pipe 9 is connected to the top of the conical guide hood 10, and the efficiency-enhancing component is used to uniformly spread the airflow downwards.

[0029] Example 2

[0030] Please see Figures 1-5Based on Example 1, a cylinder 11 is movably connected to one side of the bottom of the equipment frame 1. The free end of the cylinder 11 is movably connected to one side of the bottom of the grading box 2. A sieve plate 12 is fixedly connected to the inner cavity of the grading box 2. The aperture sizes of the three sieve plates 12 are different, decreasing from top to bottom, to facilitate grading and sieving. There are three sieve plates 12. A guide frame 13 is fixedly connected to one side of the equipment frame 1. The guide frame 13 can separate the material of each stage and discharge it separately to avoid mixing during discharge and affecting the sieving efficiency. Sliding strips 14 are fixedly connected to both sides of the inner cavity of the guide frame 13. Guide strips 15 are fixedly connected to both sides of the bottom of the sealing plate 6. Guide bar 15 and slide bar 14 can guide and support sealing plate 6. The bottom of guide bar 15 is slidably connected to the surface of slide bar 14. A feed inlet 16 is opened on one side of the top of the grading box 2. The material to be graded can be introduced through the feed inlet 16. A discharge outlet 17 is opened at the bottom of the grading box 2. The discharge outlet 17 can discharge impurities, dust and other substances from the grading box 2. A valve is installed on the surface of the discharge outlet 17. Limiting rods 18 are fixedly connected to both sides of the equipment frame 1. The function of the limiting rods 18 is to limit the block 5. The surface of the limiting rods 18 is slidably connected to one side of the inner cavity of the block 5. A spring 19 is sleeved on the surface of the slide bar 4. One end of the spring 19 is fixedly connected to one side of the block 5.

[0031] The working principle of this utility model is as follows: First, the catalyst material to be classified enters the interior of the classifier 2 through the feed inlet 16 at the top of the classifier 2 and falls onto the uppermost sieve plate 12. The blower 8 is started, and the airflow is transported to the conical guide hood 10 through the air pipe 9. After being reflected by the conical surface, it forms a uniform downward diffused turbulent flow, covering all sieve plates 12, accelerating the dispersion of the material and assisting fine particles to penetrate the sieve holes. During the screening process, the cylinder 11 keeps the classifier 2 horizontal. At this time, the spring 19 of the discharge component pushes the abutment block 5, so that the sealing plate 6 tightly locks the discharge port 3 to ensure sealing and prevent material leakage.

[0032] After screening is completed, cylinder 11 drives the bottom of the grading box 2 to rotate at a certain angle. The squeezing block 7 at the top of the discharge port 3 rotates accordingly and presses the resisting block 5. The resisting block 5 slides along the slide rod 4 and drives the sealing plate 6 to disengage from the discharge port 3. At the same time, the guide bar 15 slides along the slide bar 14 of the guide frame 13 to stabilize the guide and realize the automatic opening of the discharge port 3. The graded material is discharged through the discharge port 3 into the guide frame 13 for grading and collection. Impurities and dust are discharged through the bottom discharge port 17. After the discharge is completed, cylinder 11 resets the grading box 2 to a horizontal state, the squeezing block 7 disengages from the resisting block 5, and the spring 19 rebounds to make the sealing plate 6 reseal the discharge port 3, preparing for the next round of screening. The whole process realizes the automatic switching between screening and discharge through mechanical linkage, without the need for an additional drive device, which has both high efficiency and reliability.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
