Technical Field

[0001] This utility model relates to the field of grinding and processing equipment, and in particular to a dust removal room for casting grinding. Background Technology

[0002] In the casting grinding process, a dedicated room is typically set up as a grinding workshop, equipped with dust removal equipment. This equipment extracts dust from the workshop and prevents it from escaping and affecting the external environment. To transport the castings to the grinding workshop, tracks and conveyor platforms are required, significantly increasing the space needed for the grinding workshop.

[0003] CN200920033427 discloses a dust-removing and noise-reducing grinding chamber for grinding aluminum castings. The grinding chamber includes a grinding chamber and a settling chamber located below the grinding chamber, with a load-bearing grid between them. The grinding chamber includes a top wall, side walls, and a sealed door. A filter layer is installed on the upper part of the grinding chamber, dividing it into an air inlet and distribution layer and an operating room. An explosion-proof trolley is installed at the top of the operating room, and a work trolley track is installed at the bottom, perpendicularly passing through the sealed door. The explosion-proof trolley is perpendicular to the work trolley track. A blower is installed in the air inlet and distribution layer, and a cartridge filter is installed in the settling chamber. Sound-absorbing material is installed on the inner surfaces of the top and side walls of the grinding chamber. The grinding chamber is equipped with a work trolley and an explosion-proof crane inside the operating room to transport castings. In this way, the explosion-proof crane can only be used in the grinding chamber. Secondly, the work trolley needs to extend outside the grinding chamber for convenient transportation, and the grinding chamber requires a large space.

[0004] The technical problem that this utility model needs to solve is: how to facilitate the entry and exit of castings into and out of the grinding and dust removal room and reduce the floor space occupied by the grinding and dust removal room. Utility Model Content

[0005] The main purpose of this utility model is to provide a dust removal chamber for grinding castings. The top of the operating space can be closed or opened by the top cover module, which makes it convenient for the external crane to place the castings into the operating space for grinding. There is no need to set up a transportation mechanism, thus reducing the floor space occupied by the dust removal chamber.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A dust removal chamber for casting grinding includes a dust removal unit and side plates connected to both sides of the dust removal unit; the dust removal unit and the side plates enclose an operating space; the top of the operating space is also provided with a horizontally retractable top cover module, which is used to close the top of the operating space or to open the top of the operating space.

[0008] Preferably, the top cover module includes a movable component and a flexible fabric; one end of the flexible fabric is connected to the movable module, and the other end is connected to the top of the dust removal unit; the movable component is slidably connected to the top of the side plate.

[0009] Preferably, the flexible fabric has a frame; the frame is used to enable the flexible fabric to be folded and stored.

[0010] Preferably, the moving component includes a frame and a motor; one end of the flexible fabric is connected to the frame; the motor is connected to the frame; the power output end of the motor is provided with a roller; the top of the side plate is provided with a rolling groove; the roller and the rolling groove cooperate to make the frame drive the flexible fabric to move to close the top of the operating space or open the top of the operating space.

[0011] Preferably, it further includes a reinforcing bracket; the reinforcing bracket is connected to the lower part of the side plate; the reinforcing bracket is used to improve the stability of the side plate.

[0012] Preferably, the dust removal unit includes a fixed frame and a filter module for extracting dust from the chamber; the filter module is connected inside the fixed frame; the fixed frame has symmetrically arranged frames; the frames are hinged to the fixed frame; the frames have hinges.

[0013] Preferably, the filtration module includes a filter cartridge and an exhaust fan; a fixing component is provided on the fixing frame; the filter cartridge is threadedly connected to the fixing component; the exhaust fan is connected to the filter cartridge through the fixing component; and the exhaust fan is connected to the fixing frame.

[0015] Preferably, the side panels are detachably connected to the dust removal unit; each side panel is provided with a lifting ring at its top.

[0016] Preferably, the room is equipped with lighting.

[0017] Compared with existing technologies, this solution has the following advantages:

[0018] The grinding and dust removal chamber in this case uses a top cover module to close or open the top of the operating space. When the casting needs to be transported into the operating space, the top cover module retracts, thereby opening the top of the operating space. An external crane then lifts the casting into the operating space, eliminating the need for an additional conveying mechanism. When grinding the casting, the top cover module extends, thereby closing the top of the operating space. The dust removal unit then extracts the dust generated during grinding, reducing the probability of dust escaping to the outside.

[0019] Secondly, the grinding dust removal room is assembled in a modular way, which can be installed on any open space without the need to modify the existing factory building. It can be placed according to the space of the factory building, thereby improving the utilization rate of the factory space. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] refer to Figure 1-5 A dust removal chamber for casting grinding includes a dust removal unit 1 and side plates 2 connected to both sides of the dust removal unit 1; the dust removal unit 1 and the side plates 2 enclose an operating space 3; the top of the operating space 3 is also provided with a horizontally retractable top cover module 4, which is used to close the top of the operating space 3 or to open the top of the operating space 3.

[0029] In this embodiment, there are two side plates 2, which are connected to both sides of the dust removal unit 1 to form an operating space 3 for grinding castings. The operating space 3 has an opening side, through which workers can enter and exit the operating space 3. The top cover module 4 is located on the top of the side plate 2 and can slide on the side plate 2.

[0030] The specific operating procedure for the grinding dust removal room is as follows: the staff controls the top cover module 4 to retract, so that the top of the operating space 3 is open. The staff then controls the external crane to lift the casting into the operating space 3. After the casting is placed in the operating space 3, the staff controls the top cover module 4 to extend, so that the top of the operating space 3 is closed. After the staff turns on the dust removal unit 1, the casting is ground.

[0031] It should be noted that by using the top cover module 4 to control whether the top of the operating space 3 is closed, the opening of the top of the operating space 3 will not affect the movement of the wire rope in the crane of the external device. The crane of the external device can place the casting at any position in the operating space 3. Moreover, there is no need to set up an additional conveying mechanism, which simplifies the structure of the grinding dust removal room, reduces the floor space of the grinding dust removal room, and reduces costs.

[0032] Preferably, the top cover module 4 includes a moving component 41 and a flexible cloth 42; one end of the flexible cloth 42 is connected to the moving module, and the other end is connected to the top of the dust removal unit 1; the moving component 41 is slidably connected to the top of the side plate 2.

[0033] In this embodiment, the flexible cloth 42 is foldable. One end of the flexible cloth 42 is connected to the top of the dust removal unit 1. When the moving component 41 moves one end of the flexible cloth 42 toward the outlet of the operating space 3, the flexible cloth 42 gradually covers the top of the operating space 3, thereby sealing the top of the operating space 3. When the moving component 41 moves one end of the flexible cloth 42 away from the outlet of the operating space 3, the flexible cloth 42 gradually contracts, thereby opening the top of the operating space 3, making it convenient for the external device's crane to enter the operating space 3.

[0034] Preferably, the flexible fabric 42 is provided with a skeleton 43; the skeleton 43 is used to enable the flexible fabric 42 to be folded and stored.

[0035] In this embodiment, the flexible fabric 42 is provided with multiple skeletons 43, which are slidably connected to the side plate 2. The flexible fabric 42 and the skeletons 43 form a structure similar to a telescopic canopy. When the moving component 41 moves the flexible fabric 42, the multiple skeletons 43 follow the movement of the flexible fabric 42, causing the flexible fabric 42 to gradually unfold or fold and contract. The skeletons 43 can also increase the rigidity of the flexible fabric 42, preventing the flexible fabric 42 from drifting off the top of the side plate 2 in the event of wind, and preventing dust generated during grinding from drifting out from the top of the operating space 3.

[0036] Preferably, the moving component 41 includes a frame 411 and a motor 412; one end of the flexible fabric 42 is connected to the frame 411; the motor 412 is connected to the frame 411; the power output end of the motor 412 is provided with a roller 413; the top of the side plate 2 is provided with a rolling groove 21; the roller 413 cooperates with the rolling groove 21 to make the frame 411 drive the flexible fabric 42 to move to close the top of the operating space 3 or open the top of the operating space 3.

[0037] In this embodiment, the moving component 41 uses a motor 412 to drive the rollers 413 to rotate, thereby moving the frame 411. Both sides of the frame 411 are equipped with motors 412 and rollers 413. When the frame 411 needs to move the flexible fabric 42, the motor 412 drives the rollers 413 to rotate in the rolling groove 21, thereby causing the flexible fabric 42 to extend or retract. The use of rollers 413 and the rolling groove 21 facilitates the assembly of the moving component 41 and reduces the labor intensity of workers.

[0038] Preferably, it further includes a reinforcing bracket 5; the reinforcing bracket 5 is connected to the lower part of the side plate 2; the reinforcing bracket 5 is used to improve the stability of the side plate 2.

[0039] In this embodiment, after the side panel 2 is installed, a reinforcing bracket 5 is installed on the side panel 2. The reinforcing bracket 5 has a large contact area with the ground, which can make the side panel 2 more firmly installed and reduce the risk of the side panel 2 tipping over when it is blown by the wind or hit by a collision.

[0040] Preferably, the dust removal unit 1 includes a fixed frame 11 and a filter module 12 for extracting dust from the chamber; the filter module 12 is connected inside the fixed frame 11; the fixed frame 11 is provided with symmetrically arranged frames 13; the frames 13 are hinged to the fixed frame 11; the frames 13 are provided with hinges 131.

[0041] In this embodiment, the frame 13 is provided with hinges 131, thereby forming a louver structure. Dust generated during grinding can enter the filter module 12 through the gaps between the hinges 131, and larger particles can be prevented from entering the filter module 12 and damaging it. The frame 13 is hinged to the fixing frame 11, making it easy to open the frame 13 to replace the components of the filter module 12.

[0042] Preferably, the filter module 12 includes a filter cartridge 121 and an exhaust fan 122; a fixing member 111 is provided on the fixing frame 11; the filter cartridge 121 is threadedly connected to the fixing member 111; the exhaust fan 122 is connected to the filter cartridge 121 through the fixing member 111; and the exhaust fan 122 is connected to the fixing frame 11.

[0043] In this embodiment, the filter cartridge 121 is a dust removal filter cartridge. The top of the filter cartridge 121 is fixed to the fixing member 111 by a threaded connection, which facilitates the replacement of the filter cartridge 121. The exhaust fan 122 is connected to multiple fixing members 111, thereby connecting to multiple filter cartridges 121, thereby drawing air out of the filter cartridges 121 and causing dust to be adsorbed on the surface of the filter cartridges 121.

[0044] Furthermore, the bottom of the mounting frame 11 is provided with a collection trough 14, which is detachably connected to the bottom of the mounting frame 11. When dust enters the mounting frame 11, some of the dust will fall into the collection trough 14. Or when the filter cartridge 121 is replaced, the dust on the upper part of the filter cartridge 121 will fall into the collection trough 14, making it convenient for staff to collect the dust.

[0045] Preferably, the side plate 2 is provided with a sound-absorbing plate to reduce the noise generated during polishing.

[0046] Preferably, the side plate 2 is detachably connected to the dust removal unit 1; each side plate 2 is provided with a lifting ring 22 on its top.

[0047] In this embodiment, the entire grinding and dust removal chamber adopts a modular design. During transportation, the side plate 2 and the dust removal unit 1 can be transported separately, reducing the difficulty of transportation. During assembly, after the dust removal unit 1 is placed, the external crane uses the lifting ring 22 to place the side plate 2 on the side of the dust removal unit 1, and then fixes the side plate 2 to the dust removal unit 1 with screws.

[0048] Preferably, the room is equipped with a lighting lamp 23.

[0049] In this embodiment, when the light is dim, the lighting lamp 23 can be turned on so that the workers can see the part of the casting that needs to be polished.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
