Description

Technical Field

[0001] This utility model belongs to the field of casting grinding technology, specifically, it relates to a casting grinding device with dust collection function. Background Technology

[0002] A grinding machine is a specialized device for grinding the circumference of an object. It typically consists of an outer casing, inside which is a grinding chamber. Inside the grinding chamber are grinding components (grinding wheels or grinding belts) driven by a motor. A grinding port is located at the front of the grinding chamber. When the motor is started, the object being processed approaches the grinding component through the grinding port, and the friction between the grinding component and the object grinds the object.

[0003] When using a polishing machine, it is usually placed in a dry room. During the polishing or grinding process, fine dust is generated. The dust will spread into the air and fill the entire room. Even if the staff wears a mask, a small amount of dust will still be inhaled by the staff, which will cause harm to their health.

[0004] To address the aforementioned issues, Chinese invention patent CN112059915A discloses a grinding machine with a wastewater discharge function. It uses negative pressure airflow to guide dust to a water tank for sedimentation, thereby avoiding the limited sedimentation volume and obstruction of grinding work caused by atomized spraying. At the same time, an automatic wastewater discharge device is added to automatically transport the dust settled in the water tank to the outside of the casing, eliminating the inconvenience of manually disassembling the casing and cleaning sludge, and improving the ease of operation.

[0005] Although the grinder can guide the dust to settle and be discharged outside the casing, during grinding, the abrasive dust is sprayed downwards in a fan shape. Since the negative pressure component is located at the top of the grinder, the dust will move from bottom to top and pass by the operator's mouth and nose during the movement. Therefore, there is still a problem of the operator inhaling dust. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] To address the issue raised in the background art that although the grinding machine can guide and settle the dust before discharging it outside the casing, during grinding, the abrasive dust is sprayed downwards in a fan shape. Since the negative pressure component is located at the top of the grinding machine, the dust will move upwards from below and pass by the operator's mouth and nose during the movement, thus still causing the operator to inhale the dust. Therefore, the present invention adopts the following technical solution.

[0008] A casting grinding device with dust collection function includes a mounting frame, on which a grinding mechanism is mounted. The grinding mechanism grinds the casting. A water guide rail is detachably connected to the outer wall of the mounting frame below the grinding mechanism. The water guide rail is located below the grinding belt. A drainage groove is provided on the outer wall of the mounting frame near the inner side of the water guide rail. A spray nozzle plate is detachably connected to the inner wall of the water guide rail near the outer end of the grinding belt. Multiple drain ports are provided at the bottom of the spray nozzle plate. A water supply pipe is detachably connected to the outer wall of the spray nozzle plate. The water supply pipe is connected to a water supply.

[0009] Preferably, the ends of the drainage channels on both sides converge inside the mounting frame and extend out from the back of the mounting frame. A sewage box is detachably connected to the outer wall of the back of the mounting frame near the bottom. Limiting protrusions are fixedly connected to both sides inside the sewage box, and a filter sedimentation box is inserted between the two limiting protrusions.

[0010] Preferably, a delivery pump is installed on the mounting frame. The outlet end of the delivery pump is detachably connected to a delivery water pipe, and the inlet end of the delivery pump is detachably connected to an inlet water pipe. The inlet water pipe is inserted into the interior of the sewage box, and a water filling pipe is detachably connected to the outer wall of the sewage box. The water filling pipe is connected to an external water supply device.

[0011] Preferably, a water level sensor is installed on the inner wall of the sewage box. When the water level sensor detects that the water level is lower than the minimum threshold, it sends a signal to start the external water supply equipment to add water to the sewage box. When the water level reaches the maximum threshold, the external water supply equipment is turned off.

[0012] Preferably, the grinding assembly includes left and right opposing grinding belts, with transmission wheels sleeved inside the grinding belts on both sides. Two opposing vertical posts are provided on the inner bottom of the mounting frame. A transmission rod is fixedly connected between the left and right opposing transmission wheels. One transmission rod passes through the other vertical post. A dual-axis motor is detachably connected to one vertical post. The rotating ends of the dual-axis motor on both sides are detachably connected to the transmission rod.

[0013] Preferably, a vertical protective cover is fixedly connected to the upper end of the water guide track near the outer side. The vertical protective cover is larger than the width of the grinding belt and is a certain distance away from the grinding belt.

[0014] Preferably, an inclined baffle plate is fixedly connected to the upper end of the water guide track near the mounting frame, and the inclined baffle plate is inclined towards the mounting frame or towards the vertical protective cover.

[0015] Preferably, an air inlet pipe is detachably connected to the upper end of the mounting frame, with the air inlet end of the air inlet pipe facing the grinding area. An exhaust fan is detachably connected to the back of the mounting frame, with the air inlet end of the exhaust fan connected to the air inlet pipe. An exhaust pipe is detachably connected to the air outlet end of the air inlet pipe, and the exhaust pipe extends to the outside.

[0016] Preferably, a dust shield is detachably connected to the mounting frame above the grinding belts on both sides, and the dust shield extends diagonally downward on the outer side.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. When the grinding belt is grinding, the dust splashes downward in a fan shape. Turning on the water supply causes water to spray out from the bottom of the spray nozzle plate. The water flows out through the water guide rail and drainage groove, while the dust splashes diagonally downward and enters the interior of the water guide rail. After contacting the water, it is carried out by the water, preventing the dust from floating upward and thus reducing the risk of operators inhaling dust.

[0019] 2. Water carrying dust is discharged into the filter sedimentation box through the back of the mounting frame. The filter sedimentation box can filter the dust and allow it to settle inside. After long-term use, the filter sedimentation box can be removed to recycle the dust inside, thus enabling the dust to be reused.

[0020] 3. The filtered water inside the sewage box can be recycled by the transfer pump. When the water level inside the sewage box decreases, the water level sensor sends a signal to control the external water supply equipment to start, and water is added to the sewage box through the water inlet pipe, thereby achieving the purpose of saving water.

[0021] 4. The vertical protective cover and the inclined baffle plate can better collect the dust sprayed downwards, prevent it from spreading outwards, and make the dust collection effect better.

[0022] 5. The exhaust fan can generate suction through the air intake pipe, which can draw the air out of the work area and exhaust it outdoors through the exhaust pipe, thus exchanging the air in the work area with the outside air and keeping the air fresh. Attached Figure Description

[0034] Example 1

[0035] like Figure 1 The diagram shows a preferred embodiment of the casting grinding device with dust collection function. This embodiment includes a mounting frame 100, on which a grinding assembly is mounted. The grinding assembly includes two opposing grinding belts 101. A transmission wheel 102 is sleeved inside each grinding belt 101. Two opposing vertical posts are provided on the inner bottom of the mounting frame 100. A transmission rod is fixedly connected between the opposing transmission wheels 102. One transmission rod passes through the other vertical post. A dual-axis motor 103 is detachably connected to one vertical post. The rotating ends of the dual-axis motor 103 are detachably connected to the transmission rod. In this embodiment, the dual-axis motor 103 rotates, driving the two transmission wheels 102 to rotate, which in turn causes the grinding belts 101 to rotate. Grinding is then completed by bringing the casting into contact with the grinding belts 101.

[0036] like Figure 1 As shown, a dust shield 104 is detachably connected to the mounting frame 100 above the grinding belts 101 on both sides. The dust shield 104 extends diagonally downward on the outer side. In this embodiment, the dust shield 104 can prevent dust from splashing onto the operator's face, thereby reducing the operator's inhalation of dust.

[0037] like Figure 2 As shown, this is the embodiment of the present invention. Figure 1The enlarged structural diagram at point A shows that the mounting frame 100 is detachably connected to water guide rails 200 on both sides. The water guide rails 200 are located below the grinding belt 101. A drainage groove 201 is provided on the outer wall of the mounting frame 100 near the inner side of the water guide rails 200. A spray nozzle plate 203 is detachably connected to the inner wall of the water guide rails 200 near the outer end of the grinding belt 101. Multiple drainage ports are provided at the bottom of the spray nozzle plate 203. A water supply pipe 202 is detachably connected to the outer wall of the spray nozzle plate 203. The water supply pipe 202 is connected to a water supply. In this embodiment, when the grinding belt 101 is grinding, the dust splashes downward in a fan shape. Turning on the water supply causes water to spray out from the bottom of the spray nozzle plate 203. The water flows out through the water guide rails 200 and the drainage grooves 201, while the dust splashes diagonally downward into the interior of the water guide rails 200 and is carried out by the water flow after contacting it, so that the dust cannot float upward, thereby reducing the risk of operators inhaling dust.

[0038] like Figure 3 As shown, this is a schematic diagram of the sedimentation component structure in this embodiment. The ends of the drainage channels 201 on both sides converge inside the mounting frame 100 and exit from the back of the mounting frame 100. A wastewater box 300 is detachably connected to the outer wall of the back of the mounting frame 100 near the bottom. Limiting protrusions 304 are fixedly connected to both sides inside the wastewater box 300. A filter sedimentation box 303 is inserted between the two limiting protrusions 304. In this embodiment, water carrying dust is discharged into the interior of the filter sedimentation box 303 through the back of the mounting frame 100. The dust can be filtered and settled inside the filter sedimentation box 303. After long-term use, the filter sedimentation box 303 can be removed to recycle the dust inside, thus enabling the dust to be reused.

[0039] like Figure 3 As shown, a delivery pump is installed on the mounting frame 100. The outlet end of the delivery pump is detachably connected to the delivery water pipe 202, and the inlet end of the delivery pump is detachably connected to the inlet pipe 305. The inlet pipe 305 is inserted into the interior of the sewage box 300. A water inlet pipe 306 is detachably connected to the outer wall of the sewage box 300 and is connected to an external water supply device. A water level sensor is installed on the inner wall of the sewage box 300. In this embodiment, the water filtered inside the sewage box 300 can be recycled by the delivery pump. When the water inside the sewage box 300 decreases, the water level sensor sends a signal to control the external water supply device to start, and water is added to the sewage box 300 through the water inlet pipe 306, thereby achieving the purpose of saving water.

[0040] Example 2

[0041] like Figure 4 as well as Figure 5As shown, this is another preferred embodiment of the present invention. The difference between this embodiment and the first embodiment is that a vertical protective cover 204 is fixedly connected to the upper end of the water guide track 200 near the outer side. The vertical protective cover 204 is wider than the grinding belt 101 and is a certain distance away from the grinding belt 101. An inclined baffle 205 is fixedly connected to the upper end of the water guide track 200 near the mounting frame 100. The inclined baffle 205 can be inclined towards the mounting frame 100 or towards the vertical protective cover 204. In this embodiment, the vertical protective cover 204 and the inclined baffle 205 enable better collection of the dust sprayed downwards, preventing it from spreading outwards and resulting in a better dust collection effect.

[0042] Example 3

[0043] like Figure 6 As shown, this is another preferred embodiment of the present invention. The difference between this embodiment and Embodiments 1 and 2 is that an air inlet pipe 400 is detachably connected to the upper end of the mounting frame 100, with the air inlet end of the air inlet pipe 400 facing the grinding area. An exhaust fan 401 is detachably connected to the back of the mounting frame 100, with the air inlet end of the exhaust fan 401 connected to the air inlet pipe 400. An exhaust pipe 402 is detachably connected to the air outlet end of the air inlet pipe 400, extending to the outside. In this embodiment, the exhaust fan 401 can generate suction in the air inlet pipe 400, thereby drawing air from the working area outward and discharging it to the outside through the exhaust pipe 402, thus allowing the air in the working area to exchange with the outside and keeping the air fresh.
