Description

Technical Field

[0001] This utility model relates to the field of track grinding vehicle technology, and in particular to a track grinding filter cartridge dust collector. Background Technology

[0002] A rail grinding machine, also known as a rail grinder or rail polisher, is a specialized maintenance vehicle or train for railway tracks. It is primarily used for preventative and repair grinding of rails in rail transit lines, eliminating defects such as rust, fatigue cracks, ripples, spots, and fins on the track surface, thereby restoring the track's geometry and shape, and improving its smoothness and running quality. However, rail grinding machines generate a large amount of dust during operation, which can easily cause environmental pollution.

[0003] In the prior art, Chinese patent CN202121080032.9 discloses a dust collection device for cleaning railway grinding rails, including rails and a base plate located above the rails. Multiple rail wheels are arranged on both the left and right sides below the base plate, and the multiple rail wheels are rotatably connected to the upper end face of the rails. A main suction pipe is connected to one side of a first fan. Two dust collection boxes are located directly above the rails on both sides, and the dust collection boxes surround the top perimeter of the rails on both sides. Under the adsorption of the side fan, the grinding powder located on the top perimeter of the rails is sucked in by multiple dust collection ports and introduced into the cyclone filter cartridge dust collector through the tail dust collection pipe, thereby cleaning the grinding powder on the top perimeter of the rails and greatly improving the dust removal effect.

[0004] Although existing technologies have solved the problem of dust collection during rail grinding, the following shortcomings still exist in actual use: the use of cyclone filter cartridge dust collectors requires the combination of multi-stage suction pipes and fans to achieve dust collection, which is complex in structure, occupies a large space, is complicated to operate, has poor flexibility, and is difficult to integrate into small grinding vehicles. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing grinding rail cleaning and dust collection devices, such as complex structure, poor flexibility, and difficulty in integration with small grinding vehicles, and to provide a rail grinding filter cartridge dust collector.

[0006] This utility model is achieved through the following technical solution: a track-grinding filter cartridge dust collector includes a housing, the interior of which is divided into a dirty air chamber and a clean air chamber by a partition. An air outlet is located on the top side of the housing and connected to the clean air chamber, while an air inlet is located on the bottom side of the housing and connected to the dirty air chamber. A centrifugal fan is installed inside the clean air chamber and connected to the air outlet. A filter cartridge assembly is installed inside the dirty air chamber, with its air outlet connected to the clean air chamber.

[0009] A further improvement of this invention is that the dust extraction assembly includes a dust guide plate and a dust collection drawer. The dust guide plate is inclinedly positioned at the dust inlet, and the dust collection drawer is located directly below the dust guide plate. This design facilitates dust collection and cleaning by staff, enabling regular maintenance and reducing downtime.

[0010] A further improvement of this invention is that a pneumatic vibrator is provided on the bottom side of the dust guide plate, which is used to remove dust from the dust guide plate. This design can further improve the dust removal effect and achieve better dust removal results.

[0011] A further improvement of this invention is that a back-flushing system is installed inside the clean air chamber, and a pulse solenoid valve is installed at the back-flushing port of the back-flushing system. The back-flushing system is used to remove dust from the surface of the filter cartridge assembly. This design can further improve the dust removal effect and ensure efficient dust removal.

[0012] A further improvement of this invention is that the air outlet adopts a bent pipe structure. This design is more reasonable and can prevent foreign objects from entering the air outlet.

[0013] A further improvement of this utility model is that a cover plate A is provided on the top side of the box, and the air outlet is provided on the cover plate A.

[0014] A further improvement of this invention is that a cover plate B is provided on the top side of the box, located on the same side as cover plate A. This design facilitates disassembly and replacement by staff, making it highly practical.

[0015] A further improvement of this invention is that a removable inspection cover is provided on the rear side of the housing via an inspection port. This design facilitates routine maintenance by staff.

[0016] A further improvement of this invention is that an observation window is provided on one side of the box. This design facilitates disassembly by staff and allows them to view the internal condition of the box.

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0030] Please refer to the attached document. Figure 1 , 2 3 and 4, in conjunction with specific embodiments, are described as follows: The track-grinding filter cartridge dust collector of this utility model includes a housing 1. The interior of the housing 1 is divided into a dirty air chamber 101 and a clean air chamber 102 by a partition. An air outlet 6 is provided on the top side of the housing 1, located in the clean air chamber 102, and an air inlet 104, connected to the dirty air chamber 101, is provided on the bottom side of the housing 1. A centrifugal fan 5 is bolted into the clean air chamber 102. The machine 5 is connected to the air outlet 6; the dirty air chamber 101 is equipped with a filter cartridge assembly 2, the air outlet of the filter cartridge assembly 2 is connected to the clean air chamber 102, and the outer wall of the dirty air chamber 101 is provided with a number of air passages, which are connected to the inner cavity of the filter cartridge assembly 2; a dust removal assembly installed inside the housing 1 is provided below the dirty air chamber 101, and a dust collection port corresponding to the dust removal assembly is provided on the bottom side of the dirty air chamber 101. The dust removal assembly is used to collect and discharge dust.

[0031] The centrifugal fan 5 installed in the clean air chamber 102 of this invention draws in external air, allowing it to enter the air inlet 104. Dust-laden air enters the dirty air chamber 101 through the air inlet 104, is filtered by the filter cartridge assembly 2 installed within the dirty air chamber 101, and the filtered clean air enters the clean air chamber 102 and is discharged. It then exits through the outlet of the centrifugal fan 5, while dust remains in the dirty air chamber 101 and falls into the dust removal assembly. Finally, the dust is quickly cleaned by the dust removal assembly. This invention reduces the overall size of the equipment through its box structure, making it suitable for small rail grinding vehicles. The design of the filter cartridge assembly 2 and the centrifugal fan 5 improves the dust removal effect, ensuring efficient dust removal, and the dust removal assembly allows for quick dust removal, making operation convenient.

[0032] In one embodiment, the filter cartridge assembly 2 is a cylindrical structure with a filter surface on its outer circumferential surface. The air outlet of the filter cartridge assembly 2 is connected to the clean air chamber 102. This design significantly increases the effective filtration area. Compared with traditional planar filters or bag filters, the cylindrical structure can accommodate more filter media in a limited space, improving the dust removal efficiency per unit volume, and is especially suitable for small rail grinding vehicles with limited space. Simultaneously, the outer circumferential filter surface is connected to the clean air chamber 102 via the air outlet. Dust-laden gas enters the outer circumferential surface of the filter cartridge assembly 2 from the dirty air chamber 101, where dust is trapped on the outer surface of the filter cartridge. Clean gas then enters the clean air chamber 102 directly from the air outlet through the internal channels of the filter cartridge. This design optimizes the airflow path, reduces airflow resistance, and avoids the additional pressure loss of complex structures such as traditional venturi tubes, thereby reducing energy consumption and improving fan efficiency.

[0033] In one embodiment, the dust removal assembly includes a dust guide plate 103 and a dust collection drawer 3. The dust guide plate 103 is inclinedly disposed at the dust inlet, and the dust collection drawer 3 is disposed directly below the dust guide plate 103. This design facilitates the collection and cleaning of dust by staff, enables regular cleaning, and reduces downtime.

[0034] In one embodiment, a pneumatic vibrator 4 is provided on the bottom side of the dust guide plate 103. The pneumatic vibrator 4 is used to remove dust from the dust guide plate 103. Compressed air enters the air inlet at one end of the pneumatic vibrator 4, and the piston rod of the pneumatic vibrator 4 extends. Compressed air enters the air inlet at the other end of the pneumatic vibrator 4, and the piston rod of the pneumatic vibrator 4 retracts. This reciprocating motion realizes the high-frequency vibration of the pneumatic vibrator 4. At the same time, the side wall of the dust guide plate 103 resonates, achieving a better dust removal effect.

[0035] In one embodiment, a back-flushing system is provided in the inner cavity of the clean air chamber 102. A pulse solenoid valve is provided at the back-flushing port of the back-flushing system. The back-flushing system is used to remove dust from the surface of the filter cartridge assembly 2. Specifically, the back-flushing system is a pulse back-flushing cleaning system. Combining existing pulse back-flushing technology, the pulse back-flushing cleaning system includes components such as a pulse solenoid valve, a blowpipe, a filter cartridge, and a compressed air tank. The pulse solenoid valve issues a control system command, and high-pressure gas enters the blowpipe, generating extremely high velocity and spraying it towards the filter cartridge assembly 2. This causes the filter cartridge assembly 2 to expand and deform, generating vibration. At the same time, under the action of the reverse airflow, the dust adhering to the outer surface of the filter cartridge assembly 2 is peeled off and falls into the dust discharge assembly.

[0036] In one embodiment, the air outlet 6 adopts a bent pipe structure. This design is more reasonable and can prevent foreign objects from entering the air outlet 6.

[0037] In one embodiment, a cover plate A9 is bolted to the top side of the housing 1, and the air outlet 6 is bolted to the cover plate A9. This design allows for easy disassembly and replacement by staff, making it highly practical.

[0038] In one embodiment, a cover plate B10 is provided on the top side of the housing 1, located on one side of the cover plate A9. This design facilitates disassembly by personnel and allows them to understand the internal situation of the housing 1.

[0039] In one embodiment, a removable inspection cover 8 is provided on the rear side of the housing 1 via an inspection port 105. This design facilitates routine maintenance of the invention by staff.

[0040] In one embodiment, an observation window 7 is provided on one side of the enclosure 1. This design makes it easier for staff to view the interior of the enclosure 1.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
