Description

Technical Field

[0001] This utility model relates to the field of catalyst production equipment technology, and in particular to a novel filtration device for catalyst production. Background Technology

[0002] In catalyst production, material filtration and sieving are crucial steps to ensure product purity and particle uniformity. Traditional filtration devices often employ single-layer filtration structures, which suffer from insufficient filtration, easy clogging, and low sieving efficiency. Furthermore, material transport relies on manual labor or simple pipelines, resulting in poor continuity and preventing multi-stage continuous filtration. Moreover, material buildup during filtration negatively impacts filtration accuracy and production efficiency, failing to meet the demands of large-scale, high-precision catalyst production. Therefore, it is essential to provide a novel filtration device for catalyst production to address these shortcomings.

[0003] Therefore, it is essential to provide a novel filtration device for catalyst production to address the shortcomings of existing technologies. Utility Model Content

[0020] The present invention will be further described in conjunction with the following embodiments.

[0021] Example 1.

[0022] like Figure 1-4 As shown, a novel filtration device for catalyst production is presented. The main body of the device consists of a first filter cylinder 1 and a second filter cylinder 2 connected in series. The first filter cylinder 1 performs the primary pre-filtration function, and the second filter cylinder 2 performs the secondary fine filtration function, forming a complete continuous filtration production line.

[0023] The first filter cylinder 1 is a vertical cylindrical structure with a feed inlet 3 at the center of its top. The feed inlet 3 adopts a flared design to facilitate connection with the discharge port of the upstream production equipment and prevent material spillage. The filter tank assembly 4 is fixedly installed in the upper middle part of the first filter cylinder 1 to intercept large particulate impurities, agglomerated materials and mechanical impurities in the catalyst material, thus completing the first coarse filtration.

[0024] The filter tank assembly 4 consists of an annular groove 41, an inclined ramp 42, a filter cone 43, a filter screen 44, and a conical discharge port 45. The annular groove 41 is an outer ring material storage and guiding structure, with an inclined ramp 42 at 3°-5° along the circumference at the bottom to ensure that the material automatically converges to the center under gravity. The filter cone 43 is positioned upwards in the center of the annular groove 41, and the surface of the filter cone 43 is covered with a high-precision stainless steel filter screen 44. The mesh size of the filter screen 44 can be changed and adapted between 20 mesh and 80 mesh according to production needs. The conical discharge port 45 is located at the bottom center of the annular groove 41 and is installed vertically opposite to the filter cone 43. The material after coarse filtration flows into the conical discharge port 45 along the inclined ramp 42 and falls smoothly to the bottom of the first filter cylinder 1.

[0025] The bottom of the first filter cartridge 1 is integrally formed with the cartridge body to form a storage tank 5. The storage tank 5 has a concave material collection structure, which can temporarily store the catalyst material after coarse filtration to avoid material interruption during the pumping process. A pumping pump 6 is fixedly installed in the center of the storage tank 5. The pumping pump 6 is a corrosion-resistant magnetic pump, which is leak-free and low-noise, and can stably transport the material to the secondary filtration unit. The outlet end of the pumping pump 6 is sealed and connected to the conveying pipeline 7. The conveying pipeline 7 is a pressure-resistant hose or stainless steel rigid pipe, which extends upward along the side wall of the second filter cartridge 2 and finally connects to the upper part of the interior of the second filter cartridge 2.

[0026] The second filter cylinder 2 has a funnel groove 8 installed at the top inside. The funnel groove 8 is a flow guiding structure that is wider at the top and narrower at the bottom. The upper opening is sealed and connected to the outlet of the material conveying pipeline 7, and the lower opening is directly opposite the filter plate 9 below. This guides the material evenly to the filter plate 9, avoiding material deviation and impact that could affect the filtration effect. The filter plate 9 is fixedly connected below the funnel groove 8. The filter plate 9 is a fixed flat screen structure with a mesh size of 80 to 150 mesh, which undertakes the secondary pre-fine filtration task.

[0027] The bottom of the filter disc 9 is connected to the vibrating filter assembly 10, which is the core fine filtration unit of the device. It consists of a vibrating motor 101, a vibrating arm 102, a filter screen plate 103, a connecting rod 104, and a vibrating spring 105. The vibrating motor 101 is fixed to the outer wall of the second filter cylinder 2 by a mounting base, and its output end is rigidly connected to the vibrating arm 102. The vibrating arm 102 passes through the side wall of the second filter cylinder 2 and its end is hinged to the filter screen plate 103 to transmit vibration to the filter screen plate 103. The connecting rod 104 is vertically installed at the four corners of the filter screen plate 103, and the vibrating spring 105 is fitted on the top of the connecting rod 104. The upper end of the vibrating spring 105 is fixedly connected to the bottom of the filter disc 9 to form an elastic vibration support structure. The filter disc 9 and the filter screen plate 103 have the same diameter and are installed horizontally and parallel to each other. The mesh size of the filter screen plate 103 is 150 mesh to 300 mesh. Under the action of high-frequency vibration, fine filtration is completed quickly, effectively preventing the screen holes from clogging.

[0028] The second filter cylinder 2 has an opening 11 at the center of its bottom. A collection cylinder 12 is placed inside the opening 11. The collection cylinder 12 is located directly below the filter screen plate 103 and is used to receive and collect the final filtered catalyst product. The bottom of the collection cylinder 12 is equipped with rollers, which can be easily pulled out for unloading and cleaning.

[0029] To improve the maintainability and ease of observation of the device, a visible sealed chamber door 13 is opened on the side wall of the first filter cylinder 1 corresponding to the position of the filter tank assembly 4. The chamber door adopts a tempered glass window and silicone sealing structure, which allows real-time observation of the coarse filtration status and material blockage. After opening, the filter screen 44 can be cleaned and the screen can be replaced quickly. The top of the second filter cylinder 2 is equipped with a movable top cover 14, which corresponds to the position of the funnel trough 8 and adopts a quick-opening buckle connection, which facilitates the maintenance of the internal filter disc 9, the vibrating filter assembly 10 and the cleaning of residual materials. Four sets of fixed feet 15 are evenly connected around the bottom of the second filter cylinder 2. The fixed feet 15 have height adjustment and anti-slip and shock absorption functions to ensure stable operation of the equipment and reduce the impact of vibration displacement on the filtration accuracy.

[0030] During production, the catalyst material is evenly fed into the first filter cylinder 1 through the feed inlet 3, first falling into the filter tank assembly 4, where it undergoes coarse filtration of large impurities through the filter cone 43 and filter screen 44. The material then flows along the inclined ramp 42 into the conical discharge port 45 and enters the storage tank 5. The pump 6 is started, transporting the material in the storage tank 5 to the funnel trough 8 of the second filter cylinder 2 via the conveying pipeline 7. The material is guided through the funnel trough 8 to the filter plate 9 for secondary filtration, and then falls into the filter screen plate 103 of the vibrating filter assembly 10. The vibrating motor 101 drives the filter screen plate 103 to vibrate at high frequency, which, together with the vibrating spring 105, enhances the screening effect and completes high-precision fine filtration. Finally, the qualified material falls into the bottom collection cylinder 12, completing the entire continuous filtration process.

[0031] During operation, operators can monitor the coarse filter status in real time through the visual sealed chamber door 13, and stop the machine to clean it in time if material blockage is found. After long-term use, the movable top cover 14 can be opened to maintain the internal structure. The overall operation is simple, the operation is stable, and the filtration accuracy and efficiency are significantly better than traditional single-stage filtration equipment.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
