Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting process equipment, and more specifically, to a sandblasting dust separation device. Background Technology

[0002] Sandblasting is a dry sandblasting process. The abrasives used can be steel grit, alumina, quartz sand, silicon carbide, etc., but quartz sand is the most commonly used. Depending on the material of the part, the surface condition, and the processing requirements, different abrasive materials can be selected. In the current technology, in the process of recycling qualified abrasives, waste sand, and dust, most of the existing technologies use a three-layer screen to screen qualified abrasives, waste sand, and dust in a vibrating manner. However, due to the limited load-bearing capacity of the vibrating screen, it will be frequently crushed or worn, resulting in a short service life and reduced production efficiency. In addition, a large amount of dust is easily generated during the vibration process, causing pollution to the production environment and dust hazards to workers.

[0003] Therefore, there is an urgent need for a device that can extend the service life of abrasive recycling and separation equipment, improve production efficiency, reduce the labor intensity of workers, and reduce dust pollution. Utility Model Content

[0004] The purpose of this invention is to provide a sandblasting dust separation device. This sandblasting dust separation device improves production efficiency, reduces labor intensity for workers, minimizes dust pollution, and is adaptable to different abrasives, thus increasing its practicality.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A sandblasting dust separation device is used for the collection, dust removal, separation and recycling of abrasives. The inlet of the sandblasting dust separation device is connected to the sandblasting equipment. The sandblasting dust separation device includes: a separating sand flow tank and a separator.

[0007] The feed inlet of the separating sand trough is connected to the sandblasting equipment. The separating sand trough can separate impurities. The discharge outlet of the separating sand trough is connected to the feed inlet of the separator. The separator is located below the separating sand trough. The abrasive is separated into dust by the separator and the dust can be collected.

[0008] Preferably, the separator includes a sand-blocking and stacking mechanism, a negative pressure separation mechanism, and a housing;

[0009] The sand-blocking and stacking mechanism is disposed on the top surface of the box body. The outlet of the separate sand trough is connected to one end of the sand-blocking and stacking mechanism. The sand-blocking and stacking mechanism can stack the incoming abrasive and form an abrasive sand curtain for separating dust. A through dust separation hole is opened on the bottom side wall of the box body. The negative pressure separation mechanism is disposed outside the box body corresponding to the dust separation hole. The negative pressure separation mechanism adsorbs and collects dust in the abrasive sand curtain through the dust separation hole.

[0010] Preferably, the sand-blocking and stacking mechanism includes a plate, a sand-blocking plate disposed on the plate, and a discharge plate slidably disposed at the end of the plate;

[0011] The sand-blocking plate is connected to the plate body so that the abrasive accumulates on the plate body. The end of the plate body is provided with a plurality of snap-fit ​​holes. The discharge plate is provided with buckles corresponding to the snap-fit ​​holes, which can be snapped into the snap-fit ​​holes. The abrasive forms a sand curtain with an adjustable horizontal distance between the dust separation holes through the discharge plate.

[0012] Preferably, the plate body includes a bottom plate and three side walls;

[0013] The sidewalls are all fixedly connected to the base plate. At least two sand-blocking plates are fixedly installed on the base plate to form an abrasive accumulation. The height of the sand-blocking plates is lower than the height of the sidewalls. The end of the base plate that is not connected to the sidewalls is slidably connected to the discharge plate.

[0014] Preferably, the negative pressure separation mechanism includes a dust collector and a suction pipe;

[0015] The dust collector is installed outside the housing. The output end of the dust collector is connected to one end of the suction pipe, and the other end of the suction pipe is connected to the dust separation hole on the housing to adsorb dust in the sand curtain.

[0016] Preferably, a screen is laid on the surface of the separating sand trough, and the separating sand trough is connected to the separator through the screen.

[0017] Preferably, the mesh size of the sieve is not less than 8 mesh, and the number of layers of the sieve is not less than one.

[0018] The beneficial effects of this utility model are as follows:

[0019] This sandblasting dust separation device, through the design of a separating flow trough, separates large solid impurities such as unusable large abrasive particles, large pieces of oxide scale or paint, and other debris, collecting them in a waste bag. This prevents large solid impurities from interfering with subsequent negative pressure separation during abrasive recovery. The screen on the surface of the separating flow trough facilitates both debris separation and maintenance / replacement, extending the device's lifespan. The abrasive particles filtered and separated in the separating flow trough enter the separator and undergo negative pressure separation in the separator's negative pressure sorting zone, ensuring the quality of the recovered abrasive and preventing dust pollution.

[0020] Furthermore, the sandblasting dust separation device avoids the waste caused by frequent screen damage, which resulted in usable abrasive being mixed with waste abrasive, thus greatly saving abrasive and improving economic efficiency. Moreover, the separator can be adjusted according to the different specific gravities of various abrasives, allowing the negative pressure sorting zone to adsorb and separate abrasives of different specific gravities, thereby improving the applicability of the sandblasting dust separation device.

[0026] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] like Figure 1 As shown, a sandblasting dust separation device is used for the collection, dust removal, separation, and recycling of abrasives. The inlet of the sandblasting dust separation device is connected to the sandblasting equipment. The sandblasting dust separation device includes: a separating sand trough 1 and a separator 2. The inlet of the separating sand trough 1 is connected to the sandblasting equipment. The separating sand trough 1 can separate impurities. The outlet of the separating sand trough 1 is connected to the inlet of the separator 2. The separator 2 is located below the separating sand trough 1. The abrasives are separated into dust by the separator 2 and the dust can be collected.

[0030] In this embodiment, the sandblasting dust separation device, through the setting of the separating flow sand tank 1, separates large solid impurities such as unusable large abrasive particles, large pieces of oxide scale or paint, and other debris, and collects them into a waste bag. This prevents large solid impurities from interfering with subsequent negative pressure separation during abrasive recycling. Simultaneously, the screen on the surface of the separating flow sand tank 1 facilitates the separation of debris and also makes maintenance and replacement easy for operators, thus extending the service life of the sandblasting dust separation device. The abrasive separated by the separating flow sand tank 1 enters the separator 2 and undergoes negative pressure separation in the negative pressure sorting zone. Unsuitable abrasive particles and dust are separated from suitable abrasive particles through negative pressure adsorption. Furthermore, the separator 2 can be adjusted according to the different specific gravities of different abrasives, so that the negative pressure sorting zone of the separator 2 can adsorb and separate abrasives with different specific gravities, thereby improving the applicability of the sandblasting dust separation device, avoiding the need to constantly replace the sandblasting dust separation device to separate different abrasives, improving production efficiency and increasing economy.

[0031] like Figure 1 and Figure 2As shown, the separator 2 includes a sand-blocking and stacking mechanism 21, a negative pressure separation mechanism, and a housing 22. The sand-blocking and stacking mechanism 21 is disposed on the top surface of the housing 22. The outlet of the separation-type sand trough 1 is connected to one end of the sand-blocking and stacking mechanism 21. The sand-blocking and stacking mechanism 21 can stack the incoming abrasive and form an abrasive sand curtain for separating dust. A through dust separation hole 221 is provided on the bottom side wall of the housing 22. The negative pressure separation mechanism is disposed outside the housing 22 corresponding to the dust separation hole 221. The negative pressure separation mechanism adsorbs and collects dust in the abrasive sand curtain through the dust separation hole 221. The sand-blocking and accumulation mechanism 21 includes a plate 211, a sand-blocking plate 212 disposed on the plate 211, and a discharge plate 213 slidably disposed at the end of the plate 211. The sand-blocking plate 212 is connected to the plate 211 so that the abrasive accumulates on the plate 211. The end of the plate 211 is provided with multiple snap-fit ​​holes. The discharge plate 213 is provided with buckles corresponding to the snap-fit ​​holes that can snap into the snap-fit ​​holes. The abrasive forms a sand curtain with an adjustable horizontal distance between the dust separation holes 221 through the discharge plate 213.

[0032] In this embodiment, a sand-blocking and accumulation mechanism 21 is provided on the top of the housing 22 of the separator 2. The abrasive after being separated by the separation-type sand-flowing trough 1 gradually accumulates on the plate 211 through the sand-blocking plate 212, so that the subsequent flowing abrasive will not directly wash over the plate 211, avoiding damage to the plate 211 under long-term washing. As the abrasive accumulates, it gradually forms an inclined abrasive pile, so that the abrasive at the top of the abrasive pile slides down under the action of gravity and slides down the discharge plate 213 at the end of the plate 211 in a uniform abrasive sand curtain. When the abrasive sand curtain flows through the area directly opposite the dust separation hole 221 opened on the housing 22, the negative pressure separation mechanism connected to the dust separation hole 221 adsorbs the abrasive and dust that do not meet the screening specific gravity, thereby separating the required abrasive. Furthermore, the discharge plate 213 slidably disposed at the end of the plate 211 in the sand blocking and accumulation mechanism 21 allows the sand blocking and accumulation mechanism 21 to adjust the distance between the discharge plate 213 and the dust separation hole 221 according to the actual use requirements and the different abrasive specific gravities required, thereby adjusting the distance between the sand curtain and the dust separation hole 221 to achieve the retention of abrasives with different specific gravities.

[0033] In a preferred embodiment, the plate 211 includes a bottom plate and three side walls; the side walls are all fixedly connected to the bottom plate, and at least two sand-blocking plates 212 are fixedly provided on the bottom plate to form an abrasive accumulation. The height of the sand-blocking plates 212 is lower than the height of the side walls, and the end of the bottom plate not connected to the side walls is slidably connected to the discharge plate 213.

[0034] In this embodiment, the setting of the sand-blocking plate 212 with a height lower than the side wall ensures that when the abrasive accumulates to the point of slipping, the height of the abrasive pile does not exceed the side wall of the plate 211, thus avoiding abrasive overflow caused by excessive abrasive accumulation.

[0035] In a preferred embodiment, the negative pressure separation mechanism includes a dust collector and a suction pipe. The dust collector is located outside the housing 22, and its output end is connected to one end of the suction pipe. The other end of the suction pipe is connected to a dust separation hole 221 on the housing 22 to adsorb dust from the sand curtain. A screen is laid on the surface of the separating sand trough 1, and the separating sand trough 1 is connected to the separator 2 through the screen. The screen has a mesh size of not less than 8 mesh and has at least one layer.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
