An intake filter pre-assembly component

Abstract

An air intake filter pre-filter includes a rectangular tube with an outlet on its lower side. A lower extension frame is welded to the lower side of the rectangular tube, and a baffle is welded to the lower long side of the lower extension frame. A rotating plate is hinged to the lower end of the lower extension frame via two shafts, and the lower wall of the rotating plate abuts against the upper wall of the baffle. Multiple filter elements are disposed inside the rectangular tube. This invention uses an inclined concave shell with multiple vertically arranged baffles to block large particles of dust such as sand and gravel. When these dust particles collide with the baffles, their movement is weakened, preventing them from moving forward with the airflow. Subsequently, due to the obstruction of the front plate, these large dust particles move downward along the front plate and into the lower extension frame, thus improving the filtration effect of the filter element.

Description

Technical Field

[0001] This utility model relates to the field of air intake conveying pipeline filtration technology, and in particular to an air intake filtration pre-positioning component. Background Technology

[0002] In factories, air intake components such as air circulation systems and large gas engines require appropriate filters to remove dust and other particles from the air. Filtration prevents dust from negatively impacting the indoor environment or the operation of large gas engines. Currently used filters mostly consist of pre-filters and secondary filters. Pre-filters are used to filter large particles such as sand and gravel, a crucial process in desert regions. Secondary filters further block dust, preventing its entry. Current secondary filters use filter cloths, which suffer from reduced filtration efficiency over time and require frequent replacement, increasing operating costs. Furthermore, pre-filters often have relatively weak filtration capacity. Utility Model Content

[0003] This utility model provides an air intake filter pre-filter component to overcome the shortcomings of the prior art and solve the problem of poor filtration effect of existing filter components, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] An intake filter pre-filter component includes a rectangular tube with an outlet on its lower side. A lower extension frame is welded to the lower side of the rectangular tube, and a baffle is welded to the lower long side of the lower extension frame. A rotating plate is hinged to the lower end of the lower extension frame via two shafts, and the lower wall of the rotating plate abuts against the upper wall of the baffle.

[0006] Multiple filter elements are installed inside the rectangular tube.

[0007] Furthermore, the filter element includes a concave shell, which is inclinedly disposed inside a rectangular tube. The lower end of the concave shell is inclined towards the air intake direction along the air intake direction of the rectangular tube. The upper and lower ends of the concave shell are horizontally arranged. A fixing strip is welded to the upper inner wall of the rectangular tube and welded to the lower wall of the concave shell. A front baffle is welded to the lower inner wall of the rectangular tube. Multiple pairs of insertion holes are opened on the front baffle. The lower end of the concave shell is inserted into the insertion holes. The front baffle is located in front of the outlet.

[0008] Furthermore, the upper end of the front visor is bent with vertical stripes.

[0009] Furthermore, an inner plate is welded inside the concave shell, and multiple strip-shaped holes are formed on the inner plate. The length direction of the strip-shaped holes is parallel to the length direction of the inner plate, and the length direction of the inner plate is parallel to the length direction of the concave shell.

[0010] Furthermore, a front plate is welded to the inner wall of the concave shell, and multiple holes are opened on the front plate. The length direction of the front plate is parallel to the length direction of the concave shell, and the diameter of the holes is larger than the width of the strip hole.

[0011] Furthermore, a baffle is welded to the inner wall of the concave shell along its length. The baffle is vertically arranged, and there is a gap between the inner end of the baffle and the front wall of the front plate.

[0012] Furthermore, L-shaped plates are welded to both sides of the concave shell, and the L-shaped plates of two adjacent concave shells abut against each other and are welded and fixed at the abutment. Side elongated holes are opened on both sides of the concave shell, and the side elongated holes are located inside the L-shaped plates.

[0013] The advantages of the above technical solution are:

[0014] This invention utilizes an inclined concave shell with multiple vertically arranged baffles to block large particles of dust such as sand and gravel. When these dust particles collide with the baffles, their movement is weakened, preventing them from moving forward with the airflow. Subsequently, due to the obstruction of the front plate, these large dust particles move downwards along the front plate and into the lower extension frame. Smaller dust particles are carried by the airflow through holes in the front plate into the cavity between the front plate and the inner plate. Further obstruction by the inner plate causes some of these dust particles to be discharged downwards along the inclined surface of the inner plate. Some inevitably enter the bottom of the concave shell through the strip-shaped holes and are eventually discharged downwards along the bottom of the concave shell. The airflow is discharged outwards through the side elongated holes. During discharge, the airflow forms swirling currents at the L-shaped plate. These swirling currents cause some dust to settle downwards, thus improving the filtration effect of the filter component. Attached Figure Description

[0020] Figure 5 A three-dimensional structural diagram of the concave shell is shown. Detailed Implementation

[0021] like Figures 1-5 As shown, an intake filter pre-filter component includes a rectangular tube 1, an outlet 10 is provided on the lower side of the rectangular tube 1, a lower extension frame 11 is welded to the lower side of the rectangular tube 1, a baffle 12 is welded to the lower long side of the lower extension frame 11, a rotating plate 13 is hinged to the lower end of the lower extension frame 11 through two shafts, the lower wall of the rotating plate 13 abuts against the upper wall of the baffle 12, and multiple filter elements are provided inside the rectangular tube 1.

[0022] The filter element includes a concave shell 4, which is inclinedly disposed inside a rectangular tube 1. The lower end of the concave shell 4 is inclined towards the air intake direction along the air intake direction of the rectangular tube 1. The upper and lower ends of the concave shell 4 are horizontally disposed. A fixing strip 2 is welded to the upper inner wall of the rectangular tube 1. The fixing strip 2 is welded to the lower wall of the concave shell 4. A front baffle 3 is welded to the lower inner wall of the rectangular tube 1. A vertical strip 31 is bent at the upper end of the front baffle 3. Multiple pairs of insertion holes 30 are opened on the front baffle 3. The lower end of the concave shell 4 is inserted into the insertion hole 30. The front baffle 3 is located in front of the outlet 10.

[0023] An inner plate 40 is welded inside the concave shell 4. Multiple strip-shaped holes 41 are formed on the inner plate 40, with the length direction of the holes 41 parallel to the length direction of the inner plate 40, which in turn is parallel to the length direction of the concave shell 4. A front plate 42 is welded to the inner wall of the concave shell 4. Multiple holes are formed on the front plate 42, with the length direction of the front plate 42 parallel to the length direction of the concave shell 4. The diameter of the holes is larger than the width of the strip-shaped holes 41. A baffle 43 is welded along the length of the inner wall of the concave shell 4. The baffle 43 is vertically positioned, and there is a gap between the inner end of the baffle 43 and the front wall of the front plate 42. L-shaped plates 45 are welded to both sides of the concave shell 4. The L-shaped plates 45 of two adjacent concave shells 4 abut against each other and are welded and fixed at the abutment. Side elongated holes 44 are formed on both sides of the concave shell 4, and these side elongated holes 44 are located within the L-shaped plates 45.

[0024] The dust collected in this embodiment can be discharged from the lower end of the lower extension frame 11, which reduces the difficulty and cost compared to replacing the filter screen or filter cloth. When discharging dust, the operator can push the rotating plate 13 upward to remove the blockage on the lower end of the lower extension frame 11, thereby allowing the dust inside to be discharged outward. When airflow is introduced, the airflow acts on the rotating plate 13, causing the lower wall of the rotating plate 13 to abut against the upper wall of the baffle 12, thereby avoiding affecting the airflow. Of course, in some embodiments, the rotating plate 13 can be omitted to facilitate the rapid discharge of sand and gravel.

[0025] In this embodiment, when air is introduced, some of the sand and gravel in the air are directly ejected due to the obstruction of the baffle 43, while some fall down onto the front plate 42 because their kinetic energy is insufficient to support their forward movement, and then roll down along the front plate 42 into the lower extension frame 11. In order to prevent sand and gravel from splashing out, a corresponding front baffle 3 is also provided so that the sand and gravel can enter the lower extension frame 11. Some of the sand and gravel will not collide with the baffle plate 43 but will directly impact the front plate 42 and then roll down with the front plate 42. Some of the smaller sand and gravel will move inward through the holes and then collide with the inner plate 40 and roll down. Some of the smaller sand and gravel will enter the bottom of the concave shell 4 through the strip hole 41. Since the bottom of the concave shell 4 is closed and the amount of airflow through the strip hole 41 is small, the incoming airflow will be discharged downward along the concave shell 4. Some of it will flow back into the airflow and be discharged outward through the side elongated hole 44. During the discharge process, the airflow will form a vortex in the L-shaped plate 45, which will cause some of the fine dust to be discharged downward. The airflow will then be discharged outward along the rectangular tube 1.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
