Description

Technical Field

[0001] This utility model relates to the field of building material processing technology, and in particular to a device for filtering impurities in decorative wall powder putty. Background Technology

[0002] In modern architectural decoration and renovation projects, putty is a key material for wall base treatment, and its quality directly affects the final coating effect and the smoothness and evenness of the wall surface. High-quality putty powder requires fine particles, uniform texture, and no impurities to ensure easy application and sanding during construction, forming a dense and smooth coating. However, various impurities often become mixed in during the production, transportation, storage, and use of putty powder. These impurities mainly come from the following aspects: First, the raw materials themselves may contain foreign objects such as sand, lumps, or fibers; second, during the production and processing process, metal shavings or other materials may be mixed in due to equipment wear; third, during packaging, transportation, and long-term storage, the putty powder may clump or become mixed with dust and debris due to damaged packaging or moisture. If these impurities are not effectively removed before construction, directly using putty powder containing impurities will form bumps, particles, or scratches on the wall surface, seriously affecting the smoothness and aesthetics of the wall. In the subsequent sanding process, hard impurities may also damage sanding tools, increasing the difficulty and cost of construction. Even worse, these defects become more noticeable after the topcoat is applied, leading to rework, which not only wastes materials and labor but also delays the project schedule.

[0003] Currently, some construction workers manually sieve putty powder using simple screens before application. This method is not only inefficient and labor-intensive, making it unsuitable for large-scale construction projects, but also prone to screen clogging and inconsistent filtration. Furthermore, the open sieving process generates a large amount of dust, polluting the construction environment and harming the respiratory health of operators.

[0004] Therefore, it is necessary to design a filter device for impurities in decorative wall plaster to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of low efficiency, unstable filtration effect and easy generation of a large amount of dust, this utility model provides a decorative wall putty impurity filtration device.

[0006] The technical solution of this utility model is as follows: a decorative wall powder putty impurity filtering device, including a shell, a rotating cylinder, a funnel, a filter frame and a collection frame. The rotating cylinder is rotatably connected to the upper part of the shell, and the funnel is fixedly connected to the bottom of the rotating cylinder. The funnel has multiple slow-flow holes. The filter frame is slidably contacted at the lower part of the shell. A filter screen is provided at the bottom of the filter frame. The collection frame is slidably contacted at the lower part of the shell and is located directly below the filter frame.

[0007] In a preferred embodiment of the present invention, a feeding hopper is also included, and the feeding hopper is fixedly connected to the top of the housing.

[0008] In a preferred embodiment of the present invention, a guide tube is also included. The guide tube is fixedly connected to the top of the housing and is arranged at an angle.

[0009] In a preferred embodiment of this utility model, it further includes a supplementary shell, a motor, a rotating rod, a gear, and a gear ring. The supplementary shell is fixedly connected to the left side of the housing, and a motor is fixedly connected between the supplementary shell and the top of the housing. A rotating rod is rotatably connected inside the supplementary shell. The output shaft at the bottom of the motor is fixedly connected to the top of the rotating rod. A gear is fixedly connected to the lower part of the rotating rod. A gear ring is sleeved on the middle of the outer side of the rotating cylinder, and the gear ring meshes with the gear.

[0010] In a preferred embodiment of the present invention, a limiting block and a sliding block are further included. The limiting block is fixedly connected to the lower front side of the housing, and the sliding block is slidably connected to the limiting block. The sliding block is in sliding contact with the front side of the filter frame.

[0011] In a preferred embodiment of the present invention, a handle is also included, with the collection box having a handle fixedly connected to the front side.

[0012] The beneficial effects of this utility model are as follows: 1. By setting a funnel with multiple slow-flow holes at the bottom of the rotating cylinder, this utility model allows the putty powder to be conveyed downward in a dispersed and intermittent manner, which significantly slows down the material flow rate, further ensures filtration efficiency and quality, and avoids the generation of a large amount of dust.

[0013] 2. By setting an inclined guide tube, this utility model can guide the putty powder poured from the feed hopper to slide smoothly and dispersedly into the rotating drum, effectively avoiding blockage or splashing caused by the material directly impacting the lower structure, thus improving the stability of feeding and the cleanliness of the working environment.

[0014] 3. This utility model achieves uniform material distribution and controllable feeding through the meshing transmission structure of the motor, rotating rod, gear, gear ring and rotating cylinder, effectively preventing the filter screen from clogging due to excessive instantaneous flow.

[0015] 4. This utility model uses a sliding block and a limiting block to ensure the stability of the filter frame during operation and facilitate disassembly and cleaning, making it highly practical. Attached Figure Description

Detailed Implementation

[0021] Example: A device for filtering impurities in decorative wall plaster, such as... Figures 1-4 As shown, it includes a shell 1, a rotating cylinder 4, a funnel 10, a filter frame 11, and a collection frame 14. The rotating cylinder 4 is rotatably connected to the upper part of the shell 1, and the funnel 10 is fixedly connected to the bottom of the rotating cylinder 4. The funnel 10 has multiple slow-flow holes. The filter frame 11 is slidably contacted at the lower part of the shell 1. The filter screen is provided at the bottom of the filter frame 11. The collection frame 14 is slidably contacted at the lower part of the shell 1 and is located directly below the filter frame 11.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a feed hopper 2, which is fixedly connected to the top of the housing 1.

[0023] like Figure 2 As shown, it also includes a guide tube 3. The guide tube 3 is fixedly connected to the top of the housing 1 and is set at an angle.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a supplementary shell 5, a motor 6, a rotating rod 7, a gear 8, and a gear ring 9. The supplementary shell 5 is welded to the left side of the shell 1. The motor 6 is fixedly connected to the top of the shell 1 by bolts. The rotating rod 7 is rotatably connected inside the supplementary shell 5. The output shaft at the bottom of the motor 6 is fixedly connected to the top of the rotating rod 7. The gear 8 is fixedly connected to the lower part of the rotating rod 7. A gear ring 9 is sleeved on the middle of the outer side of the rotating cylinder 4. The gear ring 9 meshes with the gear 8.

[0025] like Figure 1 and Figure 3 As shown, it also includes a limiting block 12 and a sliding block 13. The limiting block 12 is fixedly connected to the lower front side of the housing 1, and the sliding block 13 is slidably connected to the limiting block 12. The sliding block 13 is in sliding contact with the front side of the filter frame 11.

[0026] like Figure 1 and Figure 3 As shown, it also includes a handle 15, and the front side of the collection box 14 is fixedly connected to the handle 15.

[0027] When it is necessary to filter impurities in decorative wall putty powder, the operator pours the putty powder to be filtered into the feed hopper 2 at the top of the housing 1. The putty powder first falls into the guide tube 3. Because the guide tube 3 is inclined, it guides the material to slide smoothly and dispersedly into the rotating cylinder 4 below, avoiding direct impact that could cause blockage or splashing. Then, the motor 6 is started. The output shaft of the motor 6 drives the rotating rod 7 to rotate. The gear 8 at the bottom of the rotating rod 7 rotates accordingly and meshes with the gear ring 9 sleeved on the outside of the rotating cylinder 4, thereby driving the rotating cylinder 4 to rotate continuously in the upper part of the housing 1. Under the rotation of the rotating cylinder 4, the putty powder in the cylinder is driven and gradually falls into the funnel 10, and is discharged through the slow flow hole, so that the material can be conveyed downward evenly and controllably, preventing the filter screen from being blocked by a large amount of material fed at once, and effectively inhibiting... Dust flies as putty powder discharged from funnel 10 falls into the filter frame 11 below. Fine putty powder particles can pass through the filter screen smoothly, while larger impurities are trapped on the filter screen. The qualified putty powder that passes through falls into the collection box 14 located directly below the filter frame 11, realizing the collection of pure materials. After collection, the sliding block 13 can be pulled upward, and the sliding block 13 disengages from the filter frame 11. The filter screen is no longer limited, and the filter frame 11 can be pulled out smoothly from the housing 1 for cleaning or replacement of the filter screen. Then, the sliding block 13 is released and reset downward. The limiting block 12 plays a supporting and limiting role to ensure the stability of the sliding block 13 during the sliding process and prevent the filter frame 11 from accidentally slipping off during operation. Finally, the handle 15 is manually grasped to pull the collection box 14 outward from the bottom of the housing 1 for easy pouring of the collected putty powder.
