Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a dust removal component for shot blasting of turnout accessories. Background Art

[0002] Turnout is a line connection device that allows locomotives to transfer from one track to another. Turnouts are one of the weak links of the track because of their large number, complex structure, short service life, limited train speed, low driving safety, and large maintenance investment. They are usually laid in large quantities at stations and marshalling yards and play an important role on railway lines. Due to the short service life of turnouts, their accessories are usually produced in large quantities to facilitate timely replacement of damaged accessories. In the production and processing of turnout accessories, it is necessary to perform shot blasting on the formed turnouts to improve the strength of the turnout accessories. When the shot blasting machine is used for processing, a large amount of dust is usually generated. In order to avoid dust pollution to the environment, the shot blasting machine usually needs to be equipped with a dust removal component for use to handle dust and turnout debris. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with publication number CN202666640U discloses a dust removal device for a shot blasting machine, wherein a dust removal box is provided on the frame, a fan is provided on the top of the dust removal box, a dust cleaning filter cartridge is provided in the middle of the dust removal box, an ash storage bin is provided at the bottom of the dust removal box, an air inlet is provided on the left side wall in the middle of the dust removal box, and an air outlet is provided on the right side wall of the upper part of the dust removal box. In the process of dust removal by the dust removal device, due to the small size of some of the shot blasting, the flow of air driven by the fan often drives the used shot blasting to move together, and the shot blasting and dust debris are collected together in the ash storage bin, which is not convenient for recycling the used shot blasting and increases the labor intensity of the staff;

[0004] 2. In the process of collecting dust and debris, the dust removal component for shot blasting is easily clogged by a large amount of dust. It is necessary to set up a cleaning structure to clean the filter cartridge regularly to ensure the filtration efficiency and increase the cost. By collecting dust and debris by passing the dust into water, although the filter structure does not need to be cleaned, the dust and debris need to pass through the fan and then enter the water. The sharp debris may cause wear on the fan and reduce the service life of the fan. Utility Model Content

[0005] The utility model aims to provide a dust removal component for shot blasting of turnout accessories. Through a wet dust removal pool and a dry dust removal rack, the problem is solved that when the size of the shots of the shot blasting machine is small, the dust removal component drives the air flow for dust removal and drives the shots to move at the same time, and the shots and dust need to be separated and processed later. The dust cleaning filter cartridge is easily blocked by dust. The cost of the dust removal component is increased by setting a cleaning structure to clean the dust cleaning filter cartridge regularly. The dust debris is collected by passing the dust into water, and the dust debris needs to enter the water through a fan, and the sharp debris may cause wear to the fan.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a dust removal assembly for shot blasting of turnout fittings, comprising a wet dust removal pool and a dry dust removal frame, wherein a material receiving frame is slidably clamped on the top of the wet dust removal pool, a guide frame is welded and fixed at one end of the wet dust removal pool, a discharge pipe is penetrated and clamped at the bottom of one end of the material receiving frame, a dry dust removal frame is arranged at one end of the wet dust removal pool, an exhaust fan is clamped and fixed at one end of the dry dust removal frame, a ventilation dust filter frame is clamped and fixed in the dry dust removal frame, and a dust discharge pipe and a material discharge pipe are penetrated and welded at the bottom of one side of the dry dust removal frame;

[0008] The shot blasting can be collected by the collecting rack, and the shot blasting and dust debris can be separated, so that the staff can recycle the shot blasting. When the shot blasting hits the collecting rack under the action of air flow, it will drive the vibration of the first partition net, so that the dust blocked in the first partition net can be cleaned, and the first partition net can be blocked to avoid the decrease of cleaning efficiency due to the blockage of the first partition net. The air containing dust debris can be guided by the guide rack to extend the contact time between the flowing air and the liquid surface, so that part of the dust debris falls into the water, and the first step of dust removal is performed on the larger particles of dust debris. The air flow is driven by the exhaust fan to draw the dust debris to one side of the ventilation dust filter rack, so that the debris is avoided from directly contacting the exhaust fan and extending the service life of the exhaust fan. The first dust removal is performed through the wet dust removal pool to slow down the speed of clogging of the ventilation dust filter rack. After a certain period of time, the dust exhaust pipe and the discharge pipe are opened, so that the dust debris accumulated in the dry dust removal rack and the shot blasting accumulated in the collecting rack can be discharged through the dust exhaust pipe and the discharge pipe respectively under the action of air flow. The structure is simple and the labor intensity of the staff is greatly reduced.

[0009] Furthermore, a limit frame is welded and fixed in the wet dust removal pool, a first isolation net is inserted into the material receiving rack, a vibration spring is inserted into the bottom edge of the material receiving rack, and the vibration spring is inserted into the top of the limit frame, a slide groove is provided at one end of the wet dust removal pool, and the discharge pipe is inserted into one side of the slide groove;

[0010] During dust removal, the shot and dust debris can be screened through the first partition net, so that the shot is retained in the collecting rack for collection, and the dust debris is processed through the first partition net, which is convenient for the staff to recycle the shot. When the shot collides with the first partition net with the air flow, the vibration spring can further drive the vibration of the first partition net to shake out the dust debris blocked in the first partition net, thereby avoiding the blockage of the first partition net and causing a decrease in dust removal efficiency.

[0011] Furthermore, a dust removal pipe and a sewage discharge pipe are connected through one end of the wet dust removal pool from top to bottom, the limit frame is located between the guide frame and the material receiving frame, the guide frame is located at one end of the dust removal pipe of the wet dust removal pool, and the dust removal pipe and the sewage discharge pipe are located at the bottom of one end of the guide frame;

[0012] The dust and debris passing through the first screen flow along the guide frame and adhere to the liquid surface, extending the contact time between the flowing air and the liquid surface, causing larger dust and debris to fall into the water, performing the first step of dust removal on the dust and debris, and delaying the clogging speed of the ventilation dust filter frame.

[0013] Furthermore, a connecting pipe is inserted through the bottom of one end of the dry dust removal frame, and the connecting pipe is located at the other end of the dry dust removal frame relative to the exhaust fan. A bellows and a ventilation pipe are inserted through one end of the outer peripheral surface of the connecting pipe from top to bottom, and the ventilation pipe is inserted through one end of the dust removal pipe, and the bellows is inserted through one end of the discharge pipe.

[0014] When dust removal is performed, dust debris is sucked into the inside of the dry dust removal frame through the ventilation pipe for treatment. When shot blasting is collected and dust is treated, the shot blasting is sucked into the dry dust removal frame through the bellows for collection.

[0015] Furthermore, a rotating motor is inserted through one side of the dry dust removal frame, a rotating rod is inserted through one end of the rotating motor, the rotating rod is inserted into the inner side of the dry dust removal frame, a sealing pressure plate, a scraper and a support frame are fixedly inserted through the outer peripheral surface of the rotating rod, a vent is inserted through one side of the scraper, a second partition is inserted through one side of the support frame, the ventilation dust filter frame is located between the exhaust fan and the rotating rod, the sealing pressure plate is attached to the upper side of the dust discharge pipe, the support frame is attached to the upper side of the discharge pipe, and the scraper is rotatably attached to one side of the ventilation dust filter frame;

[0016] During dust removal, air drives dust debris through the vents, and the dust debris can be processed again through the ventilation dust filter frame to avoid dust debris from polluting the environment. During shot blasting recovery, the rotating motor drives the sealing pressure plate, scraper and support frame to rotate, so that the tube plate scraper cleans the surface of the ventilation dust filter frame, and the dust debris is discharged through the dust exhaust pipe under the action of gravity, and the support frame is rotated to the top of the rotating rod, and the second partition net prevents the shot blasting from entering the dust exhaust pipe, and the accumulated shot blasting is discharged through the discharge pipe under the action of gravity, which is convenient for the staff to collect the shot blasting, and at the same time improves the functionality of the scraper and rotating motor used to clean the ventilation dust filter frame, thereby reducing production costs.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that in the process of dust removal by the dust removal device, due to the small size of some shot blasting shots, the flow of air driven by the fan often drives the used shot blasting shots to move together, and the shot blasting shots and dust debris are collected together in the ash storage bin, which is inconvenient for recycling the used shot blasting shots and increases the labor intensity of the staff. When the air flow drives the dust debris and the shot blasting shots to move, the dust debris and the shot blasting shots can be screened by the collecting rack, so that the shot blasting shots are retained in the collecting rack, and the dust debris enters the wet dust removal pool and the dry dust removal rack through the collecting rack for dust removal. When the shot blasting shots are collected, the air flow drives the shot blasting shots in the collecting rack to enter the dry dust removal rack through the discharging pipe, and finally discharged through the discharging pipe, which is convenient for the staff to recycle the shot blasting shots and improves the convenience of use.

[0019] 2. The utility model solves the problem that the dust filter cartridge of the shot blasting dust removal component is easily blocked by a large amount of dust during the collection of dust and debris by setting a wet dust removal pool and a dry dust removal rack. It is necessary to regularly clean the dust filter cartridge by setting a cleaning structure to ensure the filtration efficiency, which increases the cost. By passing the dust into water to collect the dust and debris, although the filter structure does not need to be cleaned, the dust and debris need to enter the water through the fan, and the sharp debris may cause wear to the fan and reduce the service life of the fan. When the shot blasting collides with the air flow and hits the first partition screen of the receiving rack, the dust and debris are collected by the receiving rack through the receiving rack. The vibration spring of the frame can drive the first screen to vibrate, and through the vibration, the dust and debris blocked in the first screen can be shaken out, so as to avoid the decrease of dust removal efficiency due to the blockage of the first screen. The air guided by the guide frame can be in contact with the liquid surface for a long time, so that some dust and debris fall into the water, and the first step of cleaning the dust and debris is carried out. The dust is filtered again through the ventilation dust filter frame to avoid the contact between the dust and debris and the exhaust fan, thus extending the service life of the exhaust fan. The scraper and rotating motor used for cleaning the ventilation dust filter frame can simultaneously assist the collection and discharge of shot blasting, thereby improving the functionality of the cleaning structure and reducing production costs.
