Description

Technical field:

[0001] The utility model relates to the technical field of metal processing equipment, and more specifically to a dust grinding material collecting and filtering device for casting processing. Background technology:

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] After casting, the casting needs to undergo further machining steps to make the required parts. For some machining, it is generally performed by cutting on machine tools or machining centers, and some later stages require manual processing, such as manual grinding and deburring of the surface. In this type of processing, a large amount of grinding material (small particles) and dust will fall and remain on the table. If not handled in time, they will fall to the ground or float in the air with the wind, affecting the surrounding environment. Utility model content:

[0004] The utility model aims to overcome the deficiencies of the prior art and provides a dust and grinding material collecting and filtering device for casting processing. When the casting is ground on a processing stand, the generated dust will be sucked into the main adsorption hood, and most of the dust will enter the dust collection equipment connected to the dust collection pipe along the dust collection pipe connected to the lower ventilation connector, while the generated grinding material heavier than the dust can be taken away manually or fall into the main adsorption hood from the through hole, and will fall above the bottom fixed plate and will not enter the dust collection equipment along the lower ventilation connector, thereby ensuring the normal use of the dust collection equipment, and the grinding material and dust on the processing stand can be processed in time, greatly reducing the impact on the surrounding environment, and having a good environmental protection effect.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A dust grinding material collecting and filtering device for casting processing comprises a processing stand, wherein a processing stand is fixed on the top surface of the top plate of the processing stand, and a plurality of through holes are formed on the processing stand, a main adsorption hood is fixed on the bottom surface of the top plate of the processing stand, and a sleeve portion extending downward is formed on the bottom of the main adsorption hood, and the bottom end of the sleeve portion is fixedly connected to a bottom fixing plate by bolts, and a middle through hole is formed in the middle of the bottom fixing plate, and a lower ventilation connector is fixed on the bottom surface of the bottom fixing plate, and the lower ventilation connector is communicated with the middle through hole, and an upper connecting sleeve portion is fixed in the middle of the top surface of the bottom fixing plate, and a cylindrical flat shell is formed on the top of the upper connecting sleeve portion, and the internal cavity of the cylindrical flat shell is communicated with the upper connecting sleeve portion, and the upper connecting sleeve portion is communicated with the middle through hole, and a plurality of side suction through holes are formed on the side wall of the cylindrical flat shell, and the side suction through holes are communicated with the internal cavity of the cylindrical flat shell.

[0007] A plurality of upper through holes are formed on the top plate of the processing platform, and the upper through holes correspond to and communicate with the through holes above one by one. When the casting is polished on the processing platform, the generated dust can be sucked into the main adsorption cover, reducing the pollution to the surrounding environment.

[0008] The top surface of the edge of the main adsorption cover is in a rectangular frame shape, and a rectangular frame-shaped sealing strip is sandwiched between the top surface of the edge of the main adsorption cover and the top plate of the processing platform, so as to improve the sealing performance of the connection between the two.

[0009] An outer annular ring is welded and fixed on the upper outer wall of the cylindrical flat shell, and a downwardly extending annular side plate portion is formed on the outer end bottom surface of the outer annular ring, and the annular side plate portion is located on the outer side of the outer wall of the cylindrical flat shell. The annular filter mesh is inserted into the upper part of the upper connecting sleeve portion, and the inner side wall of the middle through hole of the annular filter mesh is pressed against the upper outer wall of the upper connecting sleeve portion. The annular filter mesh covers the bottom end of the annular cavity formed between the annular side plate portion and the outer side wall of the cylindrical flat shell. An upwardly extending annular connecting portion is formed on the outer side edge of the annular filter mesh, and the annular connecting portion is inserted into the outer side of the annular side plate portion. The inner side wall of the annular connecting portion is tightly attached to the outer side wall of the annular side plate portion, and the annular connecting portion is fixedly connected to the outer side wall of the annular side plate portion by bolts.

[0010] The annular filter screen prevents oversized grinding material from being sucked into the cylindrical flat housing.

[0011] The outstanding effects of the utility model are:

[0012] When it grinds the casting on the processing bench, the generated dust will be sucked into the main adsorption hood, and most of the dust will enter the dust collection equipment connected to the dust collection pipe through the dust collection pipe connected to the lower ventilation connector. The grinding material heavier than the dust can be taken away manually or fall into the main adsorption hood from the through hole, and will fall above the bottom fixed plate and will not enter the dust collection equipment through the lower ventilation connector, thus ensuring the normal use of the dust collection equipment. The grinding material and dust on the processing bench can be processed in time, thus greatly reducing the impact on the surrounding environment, and having a good environmental protection effect.

[0015] Figure 3 It is a partial top view of the processing platform;

[0016] Figure 4 It is a partial top view of the main adsorption cover. Specific implementation method:

[0017] For example, see Figures 1 to 4 As shown, a dust grinding material collecting and filtering device for casting processing includes a processing stand 10, a processing table 11 is fixed to the top surface of the top plate of the processing stand 10, a plurality of through holes 12 are formed on the processing table 11, and all the through holes 12 cover the entire processing table 11, a plurality of upper through holes 13 are formed on the top plate of the processing stand 10, and the upper through holes 13 correspond to and communicate with the upper through holes 12 one by one, a main adsorption cover 20 is fixed to the bottom surface of the top plate of the processing stand 10, a sleeve portion 21 extending downward is formed at the bottom of the main adsorption cover 20, and a bottom end of the sleeve portion 21 is fixedly connected to a bottom fixing plate 22 by bolts, a middle through hole 221 is formed in the middle of the bottom fixing plate 22, and the bottom fixing plate 22 is fixedly connected to the bottom of the bottom fixing plate 22. A lower ventilation connector 23 is fixed to the bottom surface of 22, and the lower ventilation connector 23 is communicated with the middle through hole 221. An upper sleeve body extending upward is fixed to the middle of the top surface of the bottom fixing plate 22, and the middle vertical through hole of the upper sleeve body corresponds to and communicates with the middle through hole 221. The bottom outer wall of the upper connecting sleeve part 24 is clamped on the inner wall of the upper sleeve body, and a cylindrical flat shell 241 is formed on the top of the upper connecting sleeve part 24. The internal cavity of the flat shell 241 is communicated with the upper connecting sleeve part 24, and the upper connecting sleeve part 24 is communicated with the middle through hole 221. A plurality of side suction through holes 242 are formed on the side wall of the flat shell 241, and the side suction through holes 242 are communicated with the internal cavity of the cylindrical flat shell 241.

[0018] With this structure, when in use, the lower ventilation connector 23 is connected to the suction pipe of the external dust suction equipment through the connecting pipe (the dust suction equipment and the connecting pipe, the suction pipe and other structures are all conventional structures, which can be directly purchased on the market and will not be described in detail). The dust suction equipment is operated so that the lower ventilation connector 23 inhales air, which also causes the side suction holes 242 of the flat shell 241 to inhale air, so that the through holes 12 are all in a suction state, so that when the casting body is processed by grinding or other processing on the processing table 11, the processed powder will be sucked into the through holes 12. Among them, when some heavier grinding materials are not sucked down, they can be manually pushed from the corresponding through holes 12 into the main adsorption cover 20, or they can be manually taken and thrown into the surrounding waste bins, which makes the upper surface of the processing table 11 clean, reduces dust floating, ensures the cleanliness of the surrounding environment, and has a good environmental protection effect.

[0019] Furthermore, the top surface of the edge of the main adsorption cover 20 is in a rectangular frame shape, and a rectangular frame-shaped sealing strip 1 is sandwiched between the main adsorption cover 20 and the bottom surface of the edge of the top plate of the processing platform 10. The sealing strip 1 improves the sealing connection between the main adsorption cover 20 and the bottom surface of the edge of the top plate of the processing platform 10.

[0020] The edge of the top surface of the bottom fixing plate 22 is formed with a sleeve portion 222 extending upward, and the outer side wall of the sleeve portion 222 is closely attached to the lower inner side wall of the sleeve portion 21 .

[0021] The first sealing ring 2 is nested in the annular groove formed on the lower inner wall of the sleeve portion 21 , and the outer wall of the sleeve body portion 222 is pressed against the inner wall of the first sealing ring 2 .

[0022] A radially extending edge 231 is formed on the top outer side wall of the lower ventilation connector 23 , and a second sealing ring 3 is sandwiched between the top surface of the radially extending edge 231 and the bottom surface of the bottom fixing plate 22 .

[0023] The bottom end of the upper connecting sleeve portion 24 is welded and fixed to the top surface of the bottom fixing plate 22 .

[0024] An outer annular ring 243 is welded and fixed on the upper outer wall of the cylindrical flat shell 241, and a downwardly extending annular side plate portion 244 is formed on the outer end bottom surface of the outer annular ring 243. The annular side plate portion 244 is located at the outer side of the outer wall of the cylindrical flat shell 24, and the annular filter mesh 28 is inserted into the upper part of the upper connecting sleeve portion 24. The inner side wall of the middle through hole of the annular filter mesh 28 is pressed against the upper outer wall of the upper connecting sleeve portion 24. The annular filter mesh 28 covers the bottom end of the annular cavity formed between the annular side plate portion 244 and the outer side wall of the cylindrical flat shell 241. An upwardly extending annular connecting portion 29 is formed on the outer side edge of the annular filter mesh 28. The annular connecting portion 29 is inserted into the outer side of the annular side plate portion 244, and the inner side wall of the annular connecting portion 29 is close to the outer side wall of the annular side plate portion 244. The annular connecting portion 29 is fixedly connected to the outer side wall of the annular side plate portion 244 by bolts.

[0025] Most of the dust sucked into the main adsorption hood 20 and the grinding material dropped into the main adsorption hood 20 can pass through the annular filter mesh 28 and enter the cylindrical flat shell 24 along with the gas, and finally enter the external dust collection equipment from the lower ventilation connector 23 for treatment; the dust and the grinding material that have not entered the cylindrical flat shell 24 will be above the bottom fixed plate 22, and the bottom fixed plate 22 can be disassembled regularly so that the grinding material and part of the powder at the bottom of the sleeve part 21 can fall onto the lower bottom plate of the processing stand 10. When disassembling, a material receiving box can be placed on the lower bottom plate of the processing stand 10 below the bottom fixed plate 22, and the grinding material and part of the powder accumulated after the bottom fixed plate 22 is disassembled can be directly dropped into the material receiving box, which is very convenient, easy to clean, and has a good use effect.

[0026] When the casting is processed on the processing platform 10, the powder generated by the grinding will be sucked into the main adsorption cover 20 by the corresponding through hole 12 from time to time, which greatly reduces the pollution and impact on the surrounding air.
