Description

Technical Field

[0001] The utility model relates to the technical field of putty powder production, in particular to a filtering device for putty powder production. Background Art

[0002] Putty powder, a foundational material in the building and decoration industry, is widely used in the leveling and repair of surfaces such as walls and ceilings. Its quality is directly linked to the adhesion of subsequent coatings, the smoothness of the finished finish, and its durability over long-term use. During the putty powder production process, steps such as mixing and grinding the raw materials inevitably introduce impurities, uneven particle size, and clumping, all of which negatively impact the performance of the putty powder. Therefore, fine filtration of putty powder to remove impurities and ensure uniform particle distribution is a critical step in improving product quality and ensuring construction quality.

[0003] At present, in the field of processing paint and similar powder materials, a variety of filtering equipment has been widely used. Among them, a common design is to solve the problems of material accumulation and slow filtration in the paint filtration process by shaking the placement frame horizontally. This equipment uses the principle of mechanical vibration to shake the placement frame horizontally to make the paint continuously roll and disperse on the screening net, thereby promoting the flow and screening of materials. An auxiliary filtering device for paint processing with announcement number CN220900984U has a similar structure. The rotating motor is the driving force, and combined with the automatic reset characteristics of the elastic part, it can realize the rapid shaking of the placement frame, thereby achieving the screening frame selection of the paint. The stirring rod needs to be manually rotated.

[0004] Since large particles, lumps or sticky components in putty powder easily accumulate on the screening mesh, causing the mesh to become clogged, which in turn seriously affects the filtration rate. In this case, it is difficult to effectively solve this problem by relying solely on the lateral shaking of the placement frame. Because although lateral shaking can promote the flow of materials to a certain extent, its dispersion effect on large particles and lumps that are already densely accumulated on the mesh is limited. Therefore, based on the characteristics of putty powder, it is necessary to design a more efficient and adaptable filtering device to overcome the shortcomings of the existing technology and improve the filtration efficiency and quality of putty powder. Utility Model Content

[0005] In order to overcome the shortcomings of poor filtering effect and rate, the utility model provides a high-efficiency filtering device for putty powder production.

The filter frame is connected to the filter frame, and a motor, a cam and an elastic part are installed on the filter frame for laterally shaking the screen frame. A filter screen is connected inside the screen frame. Multiple rack sections are connected to both sides of the filter frame. Multiple rotating rods pass through the screen frame and are rotatably connected to the screen frame. Gears are connected to both ends of the rotating rod, and the gears are meshed with the racks. Multiple top blocks are connected to the rotating rod, and the top blocks are all located in the screen frame. The top blocks are squeezed and fitted with the bottom of the filter screen.

[0007] Preferably, it also includes a mounting ring, a cover plate and a sealing cover. The top of the screen frame is connected to the mounting ring, the cover plate is slidably connected to the mounting ring, the top of the cover plate is provided with a feed port, and the top of the cover plate is slidably connected to the sealing cover.

[0008] Preferably, a handle is further included, and the sealing cover is connected to the handle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Through the coordination of gears and racks, the moving rotating rod rotates, so that the top block hits the filter screen, realizing the lateral shaking of the screen frame and the up and down shaking of the filter screen, which greatly improves the screening efficiency of putty powder and prevents the accumulation of large particles and lumps on the screen, thereby ensuring the continuity and stability of the filtration process.

[0020] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," and "downwardly" are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Numerical designations such as "first" and "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0021] Example: A filter device for producing putty powder, such as Figure 1-Figure 5 As shown, it includes a filter frame 1, a screen frame 101, a rack 2, a rotating rod 3, a gear 4 and a top block 5. The screen frame 101 is connected to the filter frame 1, and a motor, a cam and an elastic member are installed on the filter frame 1. The motor drives the cam to rotate. When the cam lift section contacts the screen frame 101, the screen frame 101 moves backward and compresses the elastic member. When the cam return section contacts the screen frame 101, the elastic member rebounds and the screen frame 101 resets forward, so that the screen frame 101 reciprocates. A filter screen is connected inside the screen frame 101. Multiple racks 2 are connected on both sides of the filter frame 1. Multiple rotating rods 3 pass through the screen frame 101 and are rotatably connected to the screen frame 101. Gears 4 are connected at both ends of the rotating rod 3. The gear 4 meshes with the rack 2. Multiple top blocks 5 are connected to the rotating rod 3. The top blocks 5 are all located in the screen frame 101, and the top blocks 5 are squeezed and fitted with the bottom of the filter screen.

[0022] When filtering the putty powder, the staff turns on the motor installed on the filter frame 1. The motor cooperates with the cam and elastic parts to make the screen frame 101 move back and forth laterally, thereby realizing shaking filtration, and the lateral movement of the screen frame 101 drives the gears 4 at both ends to roll on the fixed rack 2 through the rotating rod 3, thereby realizing the rotation of the gear 4, thereby driving the rotating rod 3 to rotate. The top block 5 on the rotating rod 3 is located inside the screen frame 101, contacts the bottom of the filter screen, and lifts up the filter screen as the rotating rod 3 rotates. While the rotating rod 3 follows the reciprocating motion of the screen frame 101, it realizes reciprocating rotation, so that the top block 5 continuously knocks the filter screen, causing the filter screen to shake up and down, and the large particles and lumps on the filter screen are quickly dispersed. The putty powder has more gaps to pass through, thereby reducing blockage and no manual cleaning of the filter screen is required.

[0023] like Figure 2 and Figure 4As shown, it also includes a mounting ring 6, a cover plate 7 and a sealing cover 9. The top of the screen frame 101 is connected to the mounting ring 6, the cover plate 7 is slidably connected to the mounting ring 6, the top of the cover plate 7 is provided with a feed port 8, and the top of the cover plate 7 is slidably connected to the sealing cover 9.

[0024] During the filtering process of putty powder, since the entire sieve frame 101 is shaking, the cover plate 7 is covered in the mounting ring 6 to prevent the putty powder from escaping to the surroundings. If the device is located in the production line, open the sealing cover 9 on the top, connect the conveying pipeline, and continuously add material through the feed port 8 to optimize applicability.

[0025] like Figure 4 As shown, a handle 10 is also included. The sealing cover 9 is connected to the handle 10, and the handle 10 facilitates the movement of the sealing cover 9.

[0026] like Figure 1 and Figure 2 As shown, an observation window 11 is also included. The cover plate 7 is provided with an observation window 11 made of a transparent material. The observation window 11 provides good observation conditions, making it easy to understand the accumulation of large particles and agglomerates in the screen frame 101, and to clean the filter screen in time.

[0027] like Figure 5 As shown, it also includes a roller 12. The end of the top block 5 is rotatably connected to the roller 12, and the roller 12 is made of rubber.

[0028] The rubber roller 12 on the rotating rod 3 changes the sliding friction between the top block 5 and the filter screen into rolling friction, thereby reducing damage to the filter screen and extending the service life of the filter screen.

[0029] like Figure 2 As shown, a protective shell 13 is also included. The protective shell 13 is connected to both sides of the filter frame 1 to wrap the gear 4 and the rack 2. The rotating rod 3 is slidably connected to the protective shell 13, which effectively prevents external factors such as dust and impurities from invading the working area of ​​the gear and rack, reducing wear and failure caused by pollution.

[0030] When the putty powder enters the filtering process, the motor installed on the filter frame 1 is first started. The motor drives the screen frame 101 to reciprocate in a single direction through the coordinated action of the cam and the elastic part, causing the screen frame 101 and the built-in filter screen to vibrate laterally. The movement of the screen frame 101 drives the multiple rotating rods 3 to move laterally. Since the gears 4 at both ends of the rotating rods 3 are tightly engaged with the multi-segment racks 2 fixed on both sides of the filter frame 1, the gears 4 rotate accordingly, thereby driving the rotating rods 3 to rotate back and forth. The top blocks 5 evenly distributed on the rotating rod 3 are located inside the screen frame 101 and in contact with the bottom of the filter. As the rotating rod 3 rotates, the top blocks 5 continuously hit the filter, causing the filter to shake up and down. This dual shaking mechanism significantly enhances the screening effect, quickly disperses large particles and lumps, increases the gap for putty powder to pass through the screen, effectively reduces blockage, and avoids the tedious manual cleaning. In addition, the rubber roller 12 at the end of the top block 5 converts sliding friction into rolling friction, reducing wear on the filter and extending the service life of the filter. A cover plate 7 with a feed port 8 and a sealing cover 9 is provided on the top of the device. It is connected to the mounting ring 6 by sliding to ensure sealing during the filtration process and prevent putty powder from overflowing. The design of the handle 10 facilitates the opening and closing of the sealing cover 9. The setting of the observation window 11 allows staff to intuitively understand the situation inside the screen frame 101 and make timely cleaning decisions.
