Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically a dust extraction device for grinding castings. Background Technology

[0002] The dust generated during casting grinding (mainly metal dust and abrasive dust from grinding wheels) is highly concentrated and hard, and poses an explosion risk. Therefore, during casting grinding, a dust extraction device is needed to collect and remove the dust. A wet water curtain grinding table, also known as a water curtain dust removal table, water curtain cabinet, or wet grinding workbench, is an integrated device that combines a workbench with wet dust removal technology. It is particularly suitable for handling conditions such as casting grinding that generate heavy, high-density, high-temperature, or flammable and explosive dust.

[0003] The basic principle of a wet water curtain polishing table is to use circulating water to form a waterfall-like water curtain or screen, which serves as a filter medium to capture dust. The specific process is as follows: 1. Ventilation and guidance: After the built-in fan of the equipment is started, it will create a negative pressure (suction airflow) inside the workbench. When the operator is polishing on the workbench, the dust generated will be naturally guided by this airflow to the back of the workbench, rather than rushing towards the operator. 2. Water curtain formation: The water pump draws water from the tank to the overflow trough at the top of the workbench. The water overflows evenly from the trough and flows down a smooth slope (baffle) at the back or side, forming a complete and uniform water curtain. 3. Dust Collision with Water Curtain: The dust-laden airflow drawn in must pass through this water curtain as it passes the rear of the platform. During this process, dust particles collide violently with, become wetted by, and agglomerate with the water flow: denser dust particles (such as metal particles) are directly washed away by the water flow, while finer dust particles are enveloped by water, gain weight, and are thus separated from the air.

[0004] 4. Air-water separation and purification: The air that passes through the water curtain (now containing water droplets and residual fine dust) enters a baffle or an "S"-shaped air-water separation channel. Here, the air changes direction and speed, and the water droplets and residual moist dust separate from the air due to inertia, hitting the baffle and falling. 5. Circulation and Sedimentation: All water carrying dust eventually flows back into the bottom tank. Heavier water and dust particles settle naturally to the bottom. The relatively clean upper layer of water is then pumped away again to form a water curtain for reuse. 6. Clean air emission: Clean air, after being washed by water curtain and separated from water, is discharged outdoors by a fan through an exhaust pipe, or it can be directly circulated indoors after further filtration (depending on the nature of the dust and local environmental protection requirements). Wet water curtain polishing tables offer advantages such as high safety, efficient handling of large dust particles, no filter wear, and the ability to handle high-temperature sparks. However, in practical use, some shortcomings still exist: The wet water curtain grinding table also functions as a platform, where castings are placed for grinding. During grinding, the castings need to be positioned according to the grinding requirements. However, some heavy castings are difficult to position due to their weight. Therefore, in order to improve the platform of the wet water curtain grinding table and make it easier to position heavier castings, a dust extraction device for casting processing and grinding is provided.

[0014] 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.

[0015] Please see Figs. 1-6 In this embodiment of the utility model, a dust extraction device for grinding and polishing castings includes a wet water curtain grinding table 1 composed of a frame body 101, a grinding platform 102, and an L-shaped support frame 103. The grinding platform 102 is fixed to the front end of the frame body 101, and the L-shaped support frame 103 is fixed to the inner side of the grinding platform 102.

The platform component 2 includes a grid seat 201, a rotating groove 202, an L-shaped fixing frame 203, a base 204, and a straight groove 205.

[0016] The grid seat 201 is placed inside the grinding platform 102 and supported by the L-shaped support frame 103. The rotating groove 202 is opened in the middle of the grid seat 201. The L-shaped fixing frame 203 is distributed in a ring around the rotating groove 202 and fixed to the bottom of the grid seat 201. The base 204 is fixed in the middle of the multiple L-shaped fixing frames 203 and is concentrically distributed with the rotating groove 202.

[0017] The straight slot 205 is opened on the top of the grid seat 201 and located on one side of the rotating slot 202. The grid seat 201 is equipped with an orientation adjustment component 3 through the base 204 and the straight slot 205. The orientation adjustment component 3 is used to provide rotational support for heavier castings.

[0018] The orientation adjustment component 3 includes a rotation unit and a locking unit; the rotation unit is used to realize the rotation adjustment of the casting orientation; the locking unit is used to lock the rotation of the rotation unit to ensure the stability of the casting during grinding.

[0019] The rotating unit includes a turntable bearing 301, a rotating shaft 302, and a rotating grid disk 303. The outer ring of the turntable bearing 301 is fixed to the top of the base 204. The rotating shaft 302 is fixedly connected to the inner ring of the turntable bearing 301, and the top of the rotating shaft 302 is fixedly connected to the rotating grid disk 303. The rotating grid disk 303 is distributed inside the rotating groove 202 and is flush with the upper surface of the grid seat 201. The rotating grid disk 303 provides support for the placement of the casting, and the rotation of the rotating grid disk 303 is used to adjust the orientation of the casting.

[0020] In this embodiment, it should be noted that the wet water curtain polishing table 1 is a common specification of wet water curtain polishing table on the market. The dust collection structure inside the frame body 101 is a conventional design technology. Therefore, the dust collection structure inside the frame body 101 will not be described in detail here.

[0021] When using this wet water curtain polishing table 1, the platform component 2 with the orientation adjustment component 3 can be placed on the inner side of the front end of the polishing platform 102 as needed, or the grid seat 201 can be placed directly (it should be noted that the grid seat 201 is not equipped with a rotating groove 203, an L-shaped fixing bracket 203, or a straight groove 205).

[0022] Among them, the platform component 2, which houses the orientation adjustment component 3, is mainly used for grinding heavy castings, and its operating principle is as follows: First, place the casting on the rotating grid plate 303. At this time, the rotating handle 307 is vertically distributed, and the arc-shaped resistance plate 304 is not in contact with the rotating grid plate 303 (e.g., Figs. 1-3 That is, the rotating grid disk 303 can rotate freely, thereby enabling convenient adjustment of the orientation of the casting.

[0023] Please refer to this carefully. Figs. 1-6 The locking unit includes an arc-shaped resistance plate 304, a fixed back plate 305, a guide rod 306, a rotating handle 307, and a linkage arm 308; an L-shaped fixing frame 203 is aligned with the straight slot 205 in the horizontal direction, the arc-shaped resistance plate 304 is distributed on the side of the rotating grid plate 303 near the straight slot 205, and the fixed back plate 305 is fixed to one side of the arc-shaped resistance plate 304 and aligned with the vertical part of the L-shaped fixing frame 203.

[0024] The guide rod 306 is fixed to one side of the fixed back plate 305 and passes through the vertical part of the L-shaped fixed frame 203 to the inside of the straight groove 205. The rotating handle 307 is rotatably connected to the inside of the straight groove 205. One side of the linkage arm 308 is rotatably connected to the rotating handle 307, and the other side of the linkage arm 308 is rotatably connected to the guide rod 306.

[0025] Rotating the handle 307 downwards pushes the guide rod 306, the fixed back plate 305, and the arc-shaped resistance plate 304 closer to the rotating grid plate 303. The tight fit between the arc-shaped resistance plate 304 and the rotating grid plate 303 locks the rotation of the rotating grid plate 303.

[0026] The inner wall of the rotating groove 202 has a slot for the arc-shaped resistance plate 304 to move. The inner side of the arc-shaped resistance plate 304 and the outer side of the rotating grid disk 303 are adhered with rubber blocks to increase friction resistance, and the inner diameter of the arc-shaped resistance plate 304 matches the outer diameter of the rotating grid disk 303.

[0027] In this embodiment: after the orientation of the casting is determined, the rotating handle 307 is pulled down. The rotating handle 307 provides a pushing force to the linkage arm 308, and the linkage arm 308 provides a pushing force to the guide rod 306, so that the guide rod 306, the fixed back plate 305, and the arc-shaped resistance plate 304 move closer to the rotating grid plate 303 as a whole. Finally, the arc-shaped resistance plate 304 and the rotating grid plate 303 are tightly fitted together.

[0028] At this time, the rotation of the rotating grid plate 303 can be locked by the frictional resistance between the inner rubber block of the arc-shaped resistance plate 304 and the outer rubber block of the rotating grid plate 303, so that the rotating grid plate 303 cannot rotate. This facilitates the stable grinding of the casting (it should be added that the weight of the casting itself can ensure stability during grinding, and at the same time, the casting can be supported and fixed by an idle hand).

[0029] Please refer to this carefully. Fig. 6 Two guide rods 306 are provided vertically, and through holes are provided on the grid seat 201 and the L-shaped fixing bracket 203 for the two guide rods 306 to slide horizontally. The handle 307 is rotatably connected to a guide rod 306 above it.

[0030] In this embodiment, the structure of the two guide rods 306 provides stable guidance for the movement of the arc-shaped resistance plate 304.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
