Description

Technical Field

[0001] This utility model relates to the field of railway track engineering technology, and in particular to a dustproof ventilation and filtration device for railway track engineering. Background Technology

[0002] A ventilation system is an independent air handling system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. A ducted fresh air system consists of a fresh air unit and duct fittings. The fresh air unit purifies outdoor air and introduces it into the room, while the indoor air is exhausted through the ducts. A ductless fresh air system consists of a fresh air unit, which also purifies outdoor air and introduces it into the room.

[0003] Chinese patent CN113834157A discloses a dustproof ventilation and filtration device for railway track engineering. The dust collection bag inside the dust collection box can perform preliminary filtration of the intake air, so that dust and large particles of impurities are trapped inside the dust collection box, thereby preventing dust and large particles of impurities from entering the ventilation box. This solves the risk of internal heat generation and pipe blockage, greatly extends the service life of the device, and prevents dust from entering the room.

[0004] In the aforementioned patent documents, the top of the dust collector bag is fixedly connected to the air collection pipe, while the bottom is fixedly connected to the partition plate by screws and nuts. This makes the process of replacing the dust collector bag cumbersome, and even if the air collection pipe itself is still usable, it must be replaced along with the dust collector bag, resulting in a waste of air collection pipe material. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology: In the existing dustproof ventilation filter device, the top of the dust bag is fixedly connected to the air collection pipe, and the bottom is fixedly connected to the partition by screw and nut fasteners. This makes the process of replacing the dust bag cumbersome. Even if the air collection pipe itself is still usable, it has to be replaced along with the dust bag, resulting in a waste of air collection pipe material. Therefore, this utility model proposes a dustproof ventilation filter device for railway track engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dustproof ventilation and filtration device for railway track engineering includes a dust collection box, a dust collection bag inside the dust collection box, a first fixing ring and a second fixing ring fixedly installed at both ends of the dust collection bag, an air collecting pipe fixedly installed at the top of the dust collection box, the bottom end of the air collecting pipe penetrating the dust collection box, the first fixing ring slidingly sleeved on the bottom end of the air collecting pipe, and symmetrically vertically fixedly installed insert plates at the top, the top of the dust collection box symmetrically opening through holes, two insert plates slidably inserted into the two through holes, and locking holes opening on the surface of both insert plates, mounting blocks symmetrically fixedly installed at the top of the dust collection box, a first spring rod fixedly installed on the surface of the mounting block, and a locking block fixedly installed at the free end of the first spring rod;

[0008] The dust collector is equipped with a partition. Vertical rods are symmetrically fixed on the lower surface of the second fixing ring. The top of the partition is symmetrically provided with openings for the two vertical rods to pass through. The surface of the dust collector is provided with a sliding opening. A rod is slidably inserted into the sliding opening. A U-shaped rod and a handle are fixedly installed at both ends of the rod. The surface of the vertical rod is provided with a socket for the end of the U-shaped rod to be inserted. The handle is connected to the dust collector through a telescopic component.

[0009] Preferably, the telescopic component includes a telescopic spring sleeved on the insert rod, with both ends of the telescopic spring fixedly connected to the handle and the dust collection box, respectively.

[0010] Preferably, the top of the dust collection box is provided with a pressing component, which is used to control the two first spring rods to be stretched together.

[0011] Preferably, the pressing component includes multiple second spring rods, a retaining ring fixedly installed at the top of the multiple second spring rods, and two inclined plates. The multiple second spring rods are all vertically fixedly installed at the top of the dust collector and are distributed circumferentially around the air collection pipe. The two inclined plates are respectively fixedly installed on the upper surfaces of two locking blocks, and the lower surface of the retaining ring is arranged face-to-face with the inclined surfaces of the two inclined plates.

[0012] Preferably, the dust collection box has symmetrically and vertically rotating rotating rods, and multiple impact rollers are fixedly sleeved on the rotating rods at equal intervals. The dust collection bag is located between the multiple impact rollers, and the two rotating rods are controlled to rotate relative to each other by a lifting component.

The top of the rotating rod extends out of the dust collection box and has a vertically opened threaded groove. The threads of the two threaded rods are in opposite directions, and their bottom ends are respectively threaded into the two threaded grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The dust collector bag can be quickly disassembled and assembled by the cooperation of the locking block, insert plate, vertical rod and U-shaped rod. The disassembly and assembly steps are simple, which improves the work efficiency of disassembling and assembling dust collector bags. In addition, the dust collector bag can be removed separately to avoid replacing the air collection pipe along with the dust collector bag, which would cause waste of materials.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0026] Reference Figures 1-7 A dustproof ventilation and filtration device for railway track engineering includes a dust collection box 1, a dust collection bag 2 inside the dust collection box 1, a first fixing ring 3 and a second fixing ring 4 fixedly installed at both ends of the dust collection bag 2, an air collecting pipe 5 fixedly installed at the top of the dust collection box 1, the bottom end of the air collecting pipe 5 passing through the dust collection box 1, the first fixing ring 3 slidingly sleeved on the bottom end of the air collecting pipe 5, and symmetrically vertically fixedly installed on the top of the dust collection box 1 with insert plates 6, symmetrically opened openings at the top of the dust collection box 1, two insert plates 6 slidably inserted into the two openings respectively, and locking openings 7 opened on the surface of both insert plates 6, symmetrically fixedly installed on the top of the dust collection box 1 with mounting blocks, a first spring rod 8 fixedly installed on the surface of the mounting blocks, and a locking block 9 fixedly installed at the free end of the first spring rod 8, the longitudinal section of the locking block 9 and the insert plate 6 are both right-angled trapezoids, and the locking openings 7 are rectangular.

[0027] The dust collector 1 is equipped with a partition 10. Vertical rods 11 are symmetrically fixedly installed on the lower surface of the second fixing ring 4. The top of the partition 10 is symmetrically provided with openings for the two vertical rods 11 to pass through. The surface of the dust collector 1 is provided with a sliding opening. A rod 12 is slidably inserted into the sliding opening. A U-shaped rod 13 and a handle 14 are fixedly installed at both ends of the rod 12. The surface of the vertical rod 11 is provided with a socket 15 for the end of the U-shaped rod 13 to be inserted. The handle 14 is connected to the dust collector 1 through a telescopic component. The telescopic component includes a telescopic spring 16 sleeved on the rod 12. The two ends of the telescopic spring 16 are fixedly connected to the handle 14 and the dust collector 1, respectively.

[0028] When installing the dust bag 2, first place the dust bag 2 inside the dust collection box 1. Then, place the first fixing ring 3 around the bottom of the air collecting pipe 5, and symmetrically place the two insert plates 6 on its upper surface through the two openings. Then, control the first fixing ring 3 to move upward, so that the tops of the two insert plates 6 pass through the two openings respectively. During the upward movement of the insert plates 6, the inclined surfaces of the two insert plates 6 will slide into contact with the inclined surfaces of the two locking blocks 9 respectively. Under the pressure of the inclined surfaces, the two first spring rods 8 will retract together, and the two locking blocks 9 will move away from each other until the first fixing ring 3 moves upward until its upper surface abuts against the top wall inside the dust collection box 1. At this time, the two locking blocks 9 will correspond to the positions of the two locking holes 7 respectively. The two locking blocks 9 will then quickly move and reset under the elastic potential energy of the first spring rods 8 and insert into the two locking holes 7 respectively. The upper and lower straight edges of the locking block 9 will contact the top and bottom straight edges of the locking port 7 respectively, thus fixing the top of the dust bag 2. Then, pull the handle 14 away from the dust box 1. The telescopic spring 16 will stretch, and the U-shaped rod 13 will move until its upper surface is no longer below the two openings. Then, control the two vertical rods 11 on the lower surface of the second fixing ring 4 to align with the two openings and make their bottom ends pass through the two openings until the lower surface of the second fixing ring 4 abuts against the upper surface of the partition 10. At this time, the two ends of the U-shaped rod 13 will correspond to the positions of the two insertion ports 15 respectively. Then, release the handle 14, and the U-shaped rod 13 will move and reset quickly under the elastic potential energy of the telescopic spring 16. Its two ends will be inserted into the two insertion ports 15 respectively, thus fixing the bottom of the dust bag 2.

[0029] When it is necessary to disassemble the dust bag 2, the two first spring rods 8 can be controlled to retract together, and the handle 14 can be pulled to control the U-shaped rod 13 to move until the two locking blocks 9 are removed from the two locking ports 7 respectively, and the two ends of the U-shaped rod 13 are removed from the two insertion ports 15 respectively. This is convenient and quick, avoiding the cumbersome steps of using screws and nuts to fix the dust bag 2, improving the work efficiency of disassembling and assembling the dust bag 2, and the dust bag 2 can be removed separately, avoiding the need to replace the air collection pipe 5 along with the dust bag 2, which would cause material waste.

[0030] The top of the dust collector 1 is provided with a pressing component, which is used to control the two first spring rods 8 to be stretched together. The pressing component includes multiple second spring rods 17, a pressing ring 18 fixedly installed on the top of the multiple second spring rods 17, and two inclined plates 19. The multiple second spring rods 17 are all vertically fixedly installed on the top of the dust collector 1 and are distributed in a circle around the air collecting pipe 5. The two inclined plates 19 are respectively fixedly installed on the upper surface of the two locking blocks 9. The lower surface of the pressing ring 18 is set face to face with the inclined surfaces of the two inclined plates 19.

[0031] When it is necessary to control the two first spring rods 8 to retract together, the abutment ring 18 can be moved down so that the lower surface of the abutment ring 18 slides into contact with the inclined surfaces of the two inclined plates 19. Under the pressure of the inclined surfaces, the two first spring rods 8 will retract together.

[0032] Inside the dust collector 1, there are symmetrically and vertically rotating rotating rods 20. Multiple impact rollers 21 are fixedly sleeved on the rotating rods 20 at equal intervals. The dust bag 2 is located between the multiple impact rollers 21. The two rotating rods 20 are controlled to rotate relative to each other by a lifting component. The lifting component includes two threaded rods 22 and a lifting plate 23 fixedly installed at the top of the two threaded rods 22. The top of the rotating rod 20 passes through the dust collector 1 and has a vertically opened threaded groove. The threads of the two threaded rods 22 are opposite in direction, and the bottom ends are respectively threaded into the two threaded grooves.

[0033] The lifting plate 23 moves vertically back and forth along with two threaded rods 22. Since the two threaded rods 22 cannot rotate, the two rotating rods 20 will rotate relative to each other along with multiple impact rollers 21 due to the engagement between the threads and grooves on the surface of the threaded rods 22. During the rotation, the multiple impact rollers 21 will strike the surface of the dust collection bag 2, causing the dust adhering to the inner wall of the dust collection bag 2 to fall off. The vertical back and forth movement of the lifting plate 23 can be operated manually or by mechanical equipment, such as telescopic cylinders or electric telescopic rods, with their drive shafts fixedly connected to the lifting plate 23. Then, starting the machine will move the lifting plate 23 back and forth.

[0034] In this utility model, the dust bag 2 can be quickly disassembled and assembled through the cooperation between the locking block 9, the insert plate 6, the vertical rod 11 and the U-shaped rod 13. The disassembly and assembly steps are simple, which improves the work efficiency of disassembling and assembling the dust bag 2. The dust bag 2 can be removed separately, avoiding the need to replace the air collection pipe 5 along with the dust bag 2, thus avoiding material waste.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
