Description
Technical Field
[0001] This utility model relates to the technical field of shot blasting machine cleaning, and in particular to a overhead chain shot blasting machine equipped with a dust removal device. Background Technology
[0002] Shot blasting machines are foundry equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. They can simultaneously remove sand, cores, and clean castings. In some regions, they are also colloquially called sandblasting machines or sandblasting machines. Suspension-type shot blasting machines are often used for shot blasting large batches of small to medium-sized workpieces. Workpieces can be continuously or step-by-step transported by a suspended chain, or an advanced accumulating and pushing suspension conveyor can be used, ensuring the workpieces are stopped during loading / unloading and shot blasting, achieving fixed-point loading / unloading and fixed-point shot blasting processes. This results in high production efficiency and reliable operation. However, existing equipment generates a large amount of dust after shot blasting, causing environmental pollution.
[0003] In the prior art, CN219027186U discloses a catenary shot blasting machine with a dust removal device, including a first chamber and a second chamber. The second chamber is fixedly installed on the upper end of the first chamber. Inclined limiting plates are fixedly installed on both the left and right sides inside the first chamber. Multiple springs are equidistantly fixed on the upper end of the inclined limiting plates, and inclined support plates are fixedly installed on the upper ends of the springs. This utility model relates to the field of dust removal technology. This catenary shot blasting machine with a dust removal device uses a filter plate to retain larger dust particles, brush strips to remove residual dust from the shot, fan blades to blow away lighter dust, and then a suction pipe to draw all the dust into a vacuum cleaner for centralized processing. This achieves centralized processing of dust and workpieces from shot blasting, and is simple and convenient to operate. The inclined support plates allow the falling shot to fall from a unified inlet, and the springs installed under the inclined support plates cushion the falling shot, preventing damage to the device due to inertia.
[0004] This application can leave dust on the aluminum plate, filter the dust, and then further process the dust on the projectiles through the set brush strips to further reduce the dust on the projectiles, thereby achieving the effect of dust cleaning. However, in this application, the channel width of the brush strips will gradually narrow, which will reduce the projectile conveying efficiency when a large number of projectiles and dust fall, and easily cause blockage, thus affecting the cleaning and further use of the projectiles. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a suspension chain shot blasting machine with a dust removal device, so as to solve the technical problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A overhead conveyor shot blasting machine equipped with a dust removal device includes a dust brushing channel and two conveying channels. The bottom side of the dust brushing channel is connected to an acceleration channel. The two conveying channels are respectively connected to the two sides of the acceleration channel. An acceleration component is provided in the acceleration channel. A number of upper brushes are connected to the top of the dust brushing channel, and a number of lower brushes are connected to the top of the acceleration channel.
[0008] The acceleration assembly includes an acceleration plate, an air chamber, an air pump, and jet nozzles. The acceleration plate is fixedly installed on the inner bottom sidewall of the acceleration channel, and its two ends are respectively attached to the two wide and long sidewalls of the acceleration channel. The air chamber is opened on the end side of the acceleration plate. The air pump is fixedly installed on the wide and long side of the acceleration channel, and the output end of the air pump is connected to the air chamber. There are several jet nozzles, and several jet nozzles are respectively opened on the two long sidewalls of the acceleration plate. Several sliding grooves are opened on the inner bottom sidewall of the conveying channel, and the bottom of the sliding grooves is arc-shaped.
[0009] In a preferred embodiment, the present invention can be further configured such that the bottom sidewall of the conveying channel is inclined and tilts downward in a direction away from the acceleration plate.
[0010] In a preferred embodiment, the present invention can be further configured such that the bottom and top sidewalls of the jet nozzle are inclined, and the corresponding bottom and top sidewalls of the jet nozzle are inclined downward toward the conveying channel.
[0011] In a preferred embodiment, the present invention can be further configured such that: a plurality of cavity tubes are connected to the top side of the acceleration plate, a spring is connected inside the cavity tube, a push rod is connected to the top end of the spring, and the top end of the push rod extends to the lower brush.
[0012] In a preferred embodiment, the present invention can be further configured such that a plurality of the jet nozzles are arranged in a linear array, and each jet nozzle corresponds to an adjacent sliding groove.
[0013] In a preferred embodiment, the present invention can be further configured such that: there is a gap between two adjacent lower brushes and two adjacent upper brushes, and the top end of the push rod is located between the corresponding two lower brushes.
[0014] In summary, this utility model has at least one of the following beneficial technical effects:
[0015] 1. The overhead conveyor shot blasting machine equipped with a dust removal device can accelerate the conveying efficiency of the shot in the conveying channel by the airflow of the air pump during use, thereby enabling the shot to be reused quickly. The accelerated conveying of the shot avoids the shot from getting stuck in the acceleration channel, and ultimately avoids the shot from getting stuck due to slow conveying speed, which would affect the shot reuse effect.
[0016] 2. The overhead conveyor shot blasting machine equipped with a dust removal device has an inclined conveying channel, which allows the shot to slide or roll faster by the inclined slope of the bottom side wall of the conveying channel, thereby further improving the conveying efficiency of the shot to the dust removal port and further preventing the shot from clogging in the acceleration channel.
[0017] 3. The overhead conveyor shot blasting machine equipped with a dust removal device has an inclined bottom and top sidewall of the air jet nozzle, and the inclination angle corresponds to the inclination angle of the bottom sidewall of the conveying channel, so that the airflow can blow along the bottom sidewall of the conveying channel, reducing the loss of airflow and improving the efficiency of shot blowing.
[0018] 4. This overhead conveyor shot blasting machine with a dust removal device has a cavity tube connected to an air chamber. Airflow blown out by an air pump will enter the cavity tube, which will push the push rod, causing the push rod to move upward. The spring will also be stretched, thereby pushing the push rod to push the shot into the acceleration channel, preventing the shot from getting stuck at the lower brush. At the same time, the falling shot will hit the push rod, and with the spring retraction, the push rod will reciprocate, thus preventing the shot from getting stuck.
[0019] 5. The overhead conveyor shot blasting machine equipped with a dust removal device has air jets arranged in a linear array and corresponding to adjacent sliding grooves. This allows the air jets to spray airflow from the sliding grooves individually, thereby assisting the shot to move quickly within the sliding grooves, thus improving the shot conveying efficiency and preventing the shot from clogging due to slow conveying.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example: Refer to Figures 1-3 The present invention discloses a suspension chain shot blasting machine with a dust removal device, comprising a dust brushing channel 1 and two conveying channels 2. The bottom side of the dust brushing channel 1 is connected to an acceleration channel 3. The two conveying channels 2 are respectively connected to the two sides of the acceleration channel 3. An acceleration component 4 is provided in the acceleration channel 3. A number of upper brushes 5 are connected to the top of the dust brushing channel 1, and a number of lower brushes 6 are connected to the top of the acceleration channel 3.
[0027] The acceleration assembly 4 includes an acceleration plate 7, an air chamber 8, an air pump 9, and jet nozzles 10. The acceleration plate 7 is fixedly installed on the inner bottom side wall of the acceleration channel 3, and the two ends of the acceleration plate 7 are respectively attached to the two wide and long side walls of the acceleration channel 3. The air chamber 8 is opened on the end side of the acceleration plate 7. The air pump 9 is fixedly installed on the wide and long side of the acceleration channel 3, and the output end of the air pump 9 is connected to the air chamber 8. There are several jet nozzles 10, and several jet nozzles 10 are respectively opened on the two long side sides of the acceleration plate 7. Several sliding grooves 11 are opened on the inner bottom side wall of the conveying channel 2, and the bottom of the sliding grooves 11 is arc-shaped.
[0028] In this embodiment, during use, after being screened by the existing cleaning mechanism, the projectile will enter the dust brush channel 1. It will first pass through the upper brush 5, where it will be cleaned to reduce the dust on the projectile. A vacuum cleaner is connected to the top of the elongated side of the acceleration channel 3 to collect the cleaned dust. Then, the projectile will pass through the lower brush 6 for secondary cleaning, further cleaning the projectile and significantly reducing the dust on it. Subsequently, it will be diverted by the acceleration plate 7, so that the projectile will enter two conveying channels 2 respectively. The conveying channels 2 are connected to the conveying mechanism in the existing technology, and the projectile will enter the conveying mechanism from the conveying channel 2 for recycling.
[0029] When the projectile enters the conveying channel 2, the air pump 9 is activated. The air pump 9 will spray high-pressure air into the air chamber 8 and then discharge from the jet nozzle 10, thereby blowing the projectile to roll or move, thus accelerating the conveying of the projectile at the bottom, thereby improving the conveying efficiency of the projectile and avoiding the blockage of the projectile in the acceleration channel 3, so as to facilitate the use of the projectile.
[0030] The sliding groove 11 opened on the inner bottom side wall of the conveying channel 2 allows the projectile to enter the sliding groove 11 for conveying, avoiding excessive irregular movement of the projectile, which would cause too many projectiles to move in multiple directions and collide with each other, thereby reducing the speed of the projectile's movement or rolling and reducing the conveying efficiency of the projectile.
[0031] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, the bottom sidewall of the conveying channel 2 is inclined and slopes downward away from the acceleration plate 7.
[0032] In this embodiment, the conveying channel 2 is inclined, so that when the projectile is in the conveying channel 2, it can accelerate sliding or rolling by the inclined slope of the bottom side wall of the conveying channel 2, thereby further improving the conveying efficiency of the projectile to the dust cleaning port and further preventing the projectile from being blocked in the acceleration channel 3.
[0033] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, the bottom and top sidewalls of the jet nozzle 10 are inclined, and the corresponding bottom and top sidewalls of the jet nozzle 10 are inclined downwards towards the conveying channel 2.
[0034] In this embodiment, the bottom and top sidewalls of the jet nozzle 10 are inclined, and the inclination angle corresponds to the inclination angle of the bottom sidewall of the conveying channel 2. This allows the airflow to blow along the bottom sidewall of the conveying channel 2, reducing airflow loss and improving the efficiency of projectile blowing.
[0035] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, the top side of the acceleration plate 7 is connected to a number of cavity tubes 12, and a spring 13 is connected inside the cavity tube 12. The top end of the spring 13 is connected to a push rod 14, and the top end of the push rod 14 extends to the lower brush 6.
[0036] In this embodiment, the cavity tube 12 is connected to the air chamber 8. The airflow blown out by the air pump 9 will rush into the cavity tube 12, thereby pushing the push rod 14, causing the push rod 14 to move upward. The spring 13 will also be stretched, so that the push rod 14 pushes the projectile into the acceleration channel 3, preventing the projectile from being blocked at the lower brush 6. At the same time, the falling of the projectile will hit the push rod 14, and with the spring 13 retracting, the push rod 14 will reciprocate, thus preventing the projectile from getting blocked.
[0037] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, a plurality of jet nozzles 10 are arranged in a linear array, and each jet nozzle 10 corresponds to an adjacent sliding groove 11.
[0038] In this embodiment, the jet nozzles 10 are arranged in a linear array and correspond to adjacent sliding grooves 11 respectively. Thus, the jet nozzles 10 spray airflow from the sliding grooves 11 individually, which can assist the projectile to move quickly within the sliding grooves 11, thereby improving the projectile's conveying efficiency and preventing the projectile from becoming blocked due to slow conveying.
[0039] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, there are gaps between two adjacent lower brushes 6 and two adjacent upper brushes 5, and the top of the push rod 14 is located between the corresponding two lower brushes 6.
[0040] In this embodiment, there is a gap between two adjacent lower brushes 6 and a gap between two adjacent upper brushes 5, so that the projectile can pass through the gap between the upper brushes 5 and the lower brushes 6 and clean after touching the brushes. The top of the push rod 14 is located between the corresponding two lower brushes 6, so that the push rod 14 can push the accumulated projectile and avoid the projectile from blocking the entrance of the acceleration channel 3.
[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
