Description

Technical Field

[0001] This utility model relates to the field of sieve basket production technology, specifically a novel vertical stainless steel sieve basket. Background Technology

[0002] In centrifugal dewatering equipment, the vertical screen basket is a core filtration component, and its performance directly affects the material dewatering efficiency and equipment operational stability. Existing vertical screen baskets generally suffer from insufficient structural stability; most are fixed to the screen using only a single flange or a simple frame. During high-speed centrifugal operation, vibration can easily cause the screen to loosen and deform, shortening the basket's lifespan and potentially affecting filtration accuracy due to structural swaying.

[0003] In terms of filtration performance, traditional screen baskets mostly use parallel or equidistant arrangement of screen bars, resulting in a single direction of filtration gaps. Materials can easily pass through directly and quickly, making it difficult to fully contact the screen surface to achieve deep dewatering, resulting in poor dewatering performance. Some screen bars do not have auxiliary filtration structures and rely solely on the gaps between the screen bars for filtration, which limits the filtration area and further restricts the improvement of filtration efficiency.

[0004] In terms of material selection, existing screen baskets often use ordinary steel or low-grade stainless steel to make the screen mesh and screen bars. In dewatering operations involving corrosive or highly abrasive materials, rust and wear are prone to occur. Frequent replacements not only increase maintenance costs but also affect the continuous operation of the equipment. In addition, traditional screen bars are mostly solid structures, with a large overall weight. When the screen basket rotates at high speed, energy consumption is relatively high, indirectly increasing production and operating costs.

[0005] Meanwhile, some screen baskets lack targeted structural reinforcement designs, and the connection strength between the screen bars and supporting components is insufficient. Under long-term centrifugal force, they are prone to breakage and detachment, further increasing the risk of equipment failure. To address these issues, there is an urgent need for a vertical screen basket with a more robust structure, superior filtration effect, greater durability, and lower energy consumption to meet the requirements of efficient and stable centrifugal dewatering operations. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel vertical stainless steel sieve basket.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a novel vertical stainless steel sieve basket, comprising a first flange, a second flange, a filter screen, and reinforcing ribs. The first flange and the second flange are fixedly connected by multiple reinforcing ribs. Both the first flange and the second flange are annular in shape. The first flange, the second flange, and the reinforcing ribs form a frustum. The multiple reinforcing ribs are equidistantly distributed on the generatrix of the side of the frustum with the axis of the frustum as the center. The filter screen is frustum in shape. The multiple reinforcing ribs are fixedly connected to the outer surface of the filter screen. The top and bottom of the filter screen are fixedly connected to the first flange and the second flange, respectively. The filter screen includes a first screen bar, a second screen bar, and a support bar. The support bar is fixedly connected to the front and rear walls of the first screen bar and the second screen bar.

[0008] Preferably, the cross-sectional shape of the first and second screen bars is an isosceles trapezoid, the second screen bar is an inverted trapezoid, and the first and second screen bars are arranged alternately.

[0009] Preferably, the front surfaces of both the first and second screen bars are provided with slots, and the cross-sectional shape of the slots is rectangular.

[0010] Preferably, the cross-sectional shape of the gap between the first and second sieve bars is a parallelogram.

[0011] Preferably, the filter screen is made of stainless steel.

[0012] This utility model has the following beneficial effects:

[0013] 1. This new type of vertical stainless steel screen basket addresses the problems of insufficient structural stability and susceptibility to damage due to centrifugal vibration in traditional screen baskets. By fixing the screen mesh with flanges and reinforcing ribs, the overall structural stability is enhanced, ensuring stable operation during the centrifugal dewatering process. The buffering effect of the reinforcing ribs also reduces impact friction, solving the problem of short lifespan of traditional screen baskets. At the same time, the fixed connection between the stainless steel screen mesh and the support bars further improves the structural strength, extends the service life of the equipment, and compensates for the easy wear and tear caused by material and structural defects in traditional screen baskets.

[0014] 2. This new type of vertical stainless steel screen basket addresses the problems of poor filtration and insufficient dewatering performance of traditional screen baskets. By alternating the screen bars to form inclined gaps, combined with the slotted structure on the screen bars, it not only improves the filtration accuracy and dewatering efficiency, solving the problem of insufficient filtration caused by materials passing directly through, but also reduces the weight of the screen bars by slotting, reducing rotational energy consumption and solving the problem of high energy consumption in traditional equipment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figure 1-2 As shown, this utility model embodiment provides a novel vertical stainless steel sieve basket, including a first flange 1, a second flange 2, a filter screen 3, and reinforcing ribs 4. The first flange 1 and the second flange 2 are fixedly connected by multiple reinforcing ribs 4. The first flange 1 and the second flange 2 are both annular in shape. The first flange 1, the second flange 2, and the reinforcing ribs 4 form a frustum. Multiple reinforcing ribs 4 are equidistantly distributed on the generatrix of the side of the frustum with the axis of the frustum as the center. The filter screen 3 is frustum in shape. Multiple reinforcing ribs 4 are fixedly connected to the outer surface of the filter screen 3. The top and bottom of the filter screen 3 are fixedly connected to the first flange 1 and the second flange 2, respectively. The filter screen 3 includes a first screen bar 5, a second screen bar 6, and a support bar 8. The support bar 8 is fixedly connected to the front and rear walls of the first screen bar 5 and the second screen bar 6.

[0020] The cross-sectional shape of the first screen bar 5 and the second screen bar 6 is an isosceles trapezoid, while the second screen bar 6 is an inverted trapezoid. The first screen bar 5 and the second screen bar 6 are arranged alternately. Due to the alternating arrangement of the first screen bar 5 and the second screen bar 6, an inclined gap is formed between them, which can prevent materials from directly passing through the filter screen 3, thereby improving the filtration effect of the filter screen 3 and enhancing the dewatering performance of the screen basket. The front surfaces of both the first screen bar 5 and the second screen bar 6 are perforated with slots 7. The cross-sectional shape of the slots 7 is rectangular. By opening the slots on the first screen bar 5 and the second screen bar 6... The slots 7 on the first screen bar 5 and the second screen bar 6 allow for filtration using the sieve basket, thereby further improving the filtration effect of the filter screen 3. Furthermore, the slots 7 reduce the weight of the first screen bar 5 and the second screen bar 6, thus reducing the energy consumed during the rotation of the sieve basket and lowering production costs. The cross-sectional shape of the gap between the first screen bar 5 and the second screen bar 6 is a parallelogram, facilitating filtration and dewatering within this gap. The filter screen 3 is made of stainless steel, which helps extend its service life.

[0021] Working Principle: When using the new vertical stainless steel screen basket, the first flange 1, the second flange 2, and the reinforcing rib 4 together fix the filter screen 3, making the screen basket structure more stable and maintaining stability during centrifugal dewatering. Simultaneously, the reinforcing rib 4 improves the buffering force of the screen basket, reducing impact and friction and extending its service life. The stainless steel filter screen 3 is beneficial for extending its own service life. The support bar 8 fixes the first screen bar 5 and the second screen bar 6, making the structure of the filter screen 3 more stable and further improving its service life. The alternating arrangement of the first screen bar 5 and the second screen bar 6 creates an inclined gap, preventing material from directly passing through the filter screen 3. This improves the filtration effect of the filter screen 3 and enhances the dewatering performance of the screen basket. Furthermore, the slots 7 on the first screen bar 5 and the second screen bar 6 participate in the filtration process, further improving the filtration effect of the filter screen 3. The slots 7 also reduce the impact on the first screen bar 5 and the second screen bar 6. The weight is reduced, thereby reducing energy consumption when the screen basket rotates, which helps to reduce production costs.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
