[0002] Currently, sandblasting is the most effective process for treating the external surface of steel. It can remove rust from the surface of the workpiece. After sandblasting, the surface of the workpiece can be painted, and the effect is more stable and better. Different sandblasting processes use different abrasives. Dry sandblasting can use abrasives such as steel grit, alumina, quartz sand, and silicon carbide, but quartz sand is the most widely used. Wet sandblasting is to mix the above abrasives with water to form a slurry abrasive.

[0003] Currently, sandblasting machines often generate a large amount of particulate dust during operation. Sandblasting machines are generally equipped with exhaust fans to extract the internal particulate dust and remove it through dust collection bags. However, during long-term use, particulate dust will gradually adhere to and clog the inner wall of the dust collection bags, requiring manual disassembly and replacement for cleaning, which is quite inconvenient.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-3 The dust removal mechanism shown includes a dust removal box 1, and an air inlet pipe 2 is provided on one side of the dust removal box 1.

[0033] Furthermore, the dust collection box 1 is equipped with a collection mechanism 3, which includes a fixing frame 31, dust bags 32, a collection box 33, and a shaking component 34. The fixing frame 31 is fixedly connected to the inside of the dust collection box 1. Multiple dust bags 32 are all set on the top of the fixing frame 31 and are installed upside down on the fixing frame 31 to remove dust from the gas input by the air inlet pipe 2. The collection box 33 is slidably inserted and connected to one side of the dust collection box 1. The shaking component 34 is set inside the dust collection box 1 and is used to clean the dust bags 32. The collection box 33 can directly collect a portion of the dust filtered out by the dust bags 32, and can also collect the dust shaken off when the shaking component 34 drives the multiple dust bags 32 to shake.

[0034] Specifically, the shaking assembly 34 includes: a sliding plate 341, squeezing rods 342, connecting ropes 343, a fixing rod 344, and a rotating rod 345. The sliding plate 341 is slidably inserted into the inner cavity of the dust collection box 1. One end of each of the multiple squeezing rods 342 is fixedly connected to the bottom end of the sliding plate 341 at equal intervals. The other end of each of the multiple squeezing rods 342 is provided with a connecting groove. One end of each of the multiple connecting ropes 343 is fixedly connected to a dust collection bag 32, and the other end of each of the multiple connecting ropes 343 cooperates with the connecting groove. The multiple dust collection bags 32 can be tied to the bottom of the multiple squeezing rods 342 through the connecting ropes 343, and are in an unfolded state under the pull of the squeezing rods 342, facilitating the entry of dust collection bags into the dust collection box 1. Dust removal operation is performed; one end of the fixed rod 344 is fixedly connected to the sliding plate 341, and the other end of the fixed rod 344 is slidably inserted into the top of the inner wall of the dust collection box 1; a rotating groove is opened at the top of the fixed rod 344, and the rotating rod 345 is slidably inserted into the inner cavity of the rotating groove. When it is necessary to clean the dust collection bag 32, the rotating rod 345 can be rotated to be in the same straight line as the fixed rod 344, and the sliding plate 341 can be pulled up and down to drive multiple squeezing rods 342 to turn out the inside of multiple dust collection bags 32 and shake them, thereby cleaning the dust particles attached to the inside of the dust collection bag 32 without disassembly and cleaning.

[0035] Furthermore, limit grooves are provided on both sides of the sliding plate 341, and limit blocks 4 are fixedly connected to both sides of the sliding plate 341. The limit blocks 4 are slidably inserted into the inner cavity of the limit grooves. The setting of the limit blocks 4 plays a limiting role on the sliding plate 341, so that the sliding plate 341 can only move in the vertical direction under the push of the rotating rod 345.

[0036] Furthermore, the shaking assembly 34 also includes: a positioning rod 346, a pull rod 347, and a compression spring 348. A positioning groove is provided at the top of the dust collector 1, and a positioning hole is provided at the bottom of the rotating rod 345. One end of the positioning rod 346 is slidably inserted into the inner cavity of the positioning groove, and the other end of the positioning rod 346 is slidably inserted into the inner cavity of the positioning hole. The pull rod 347 is fixedly connected to one side of the positioning rod 346. A pull groove is provided on one side of the dust collector 1, and the pull rod 347 is slidably inserted into the inner cavity of the pull groove. The positioning rod 346 can be pulled by the pull rod 347. This allows the positioning rod 346 to disengage from the positioning hole, thus eliminating the positioning of the rotating rod 345. The compression spring 348 is located inside the positioning groove. One end of the compression spring 348 is fixedly connected to the positioning rod 346, and the other end is fixedly connected to the inner wall of the positioning groove. The compression spring 348 is always in a compressed state, thus providing a stable upward elastic force to the positioning rod 346. This allows the rotating rod 345 to be positioned by the positioning rod 346 when not in use, thereby reducing the footprint of the entire dust removal mechanism and making it easier to use.

[0037] Furthermore, guide plates 5 are fixed on both sides of the inner wall of the dust collection box 1. The top of each guide plate 5 is provided with an inclined surface. The inclined surface makes it easy for dust to be accurately guided into the inside of the collection box 33 when it falls, so as to facilitate the collection of dust particles.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
