Description

Technical Field

[0001] The invention belongs to the technical field of sandblasting, and in particular relates to a sandblasting room and a coating production line. Background Art

[0002] In the coating process, the workpiece to be coated will accumulate unnecessary sputtering after long-term use. These sputterings will affect the quality and uniformity of the coating, so sandblasting is required. Sandblasting is the most thorough and common surface cleaning method. By using compressed air to spray abrasives such as diamond sand onto the surface of the workpiece at high speed, it can effectively remove rust, oxide layer and other contaminants on the surface of the workpiece, laying a good foundation for subsequent coating or plating. The surface of the workpiece after sandblasting becomes rough, which increases the contact area with the coating or plating, thereby improving adhesion.

[0003] However, the common sandblasting process is that the operator wears dust-proof clothing to sandblast in the sandblasting room. The sandblasting process will generate a lot of dust, and the working environment is relatively poor, which affects the health and safety of the workers. In addition, the sand material cannot be recycled, resulting in a waste of resources. Summary of the invention

[0028] See also Figures 1 to 4 The embodiment of the present application provides a sandblasting room for cooperating with a sandblasting device to perform sandblasting on a target workpiece 200. The sandblasting room includes a room body 10 with a accommodating space, a supporting structure 20 for supporting the room body 10, and a collecting structure 30 arranged at the bottom of the room body 10. The target workpiece 200 is accommodated in the accommodating space. The room body 10 is provided with a sandblasting port 13 connected to the accommodating space. The sandblasting port 13 is used for the sandblasting device to spray material to the target workpiece 200. The bottom of the room body 10 is provided with an opening 15 connected to the accommodating space. The collecting structure 30 includes a hopper 31 connected to the opening 15 and a vibrator 32 arranged on the inner wall of the hopper 31. The vibrator 32 is used to drive the inner wall of the hopper 31 to vibrate so as to cause the spray material to be discharged through the hopper 31.

[0029] It should be noted that sandblasting is a process for treating the surface of a workpiece. The sandblasting device uses compressed air as a power source to form a high-speed jet beam to spray the material at high speed onto the surface of the target workpiece 200, thereby changing the appearance or shape of the workpiece surface.

[0030] It can be understood that the sandblasting device of the present application can be a sandblasting gun, and the blasting material can be corundum, copper ore sand, quartz sand, corundum, iron sand, sea sand, etc.

[0031] The sandblasting room provided by the present application sets the target workpiece 200 in the room body 10, and the operator can spray the material onto the target workpiece 200 in the room body 10 through the sandblasting port 13 outside the room body 10, thereby isolating the dust generated by the sandblasting, effectively ensuring the safety and health of the operator, and the sprayed material can be discharged outward through the hopper 31 under the action of gravity for recycling and reuse, thereby improving resource utilization; in addition, the vibrator 32 can drive the hopper 31 to vibrate, thereby accelerating the discharge of the material through the hopper 31, thereby improving the efficiency of material recovery.

[0032] Optionally, the vibrating member 32 may be a vibrating motor, which is an exciting source that combines a power source and a vibration source. The vibrating motor has a set of adjustable eccentric blocks installed at each end of the rotor shaft, and utilizes the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks to obtain exciting force.

[0033] The exciting force and power of the vibrating motor are properly matched, with strong vibration force, light body weight, small size and low mechanical noise; and because the vibrating motor is a strong resistance type vibration rather than resonance, it has a stable amplitude; the vibration frequency range of the vibrating motor is large, and the vibration frequency of the vibrating motor can be adjusted over a wide range by adjusting the speed, and the vibration frequency and amplitude can be arbitrarily selected according to different paths; the vibrating motor is less affected by power supply fluctuations, and the electromagnetic exciter will cause a large change in the exciting force due to voltage changes, but in the vibration motor, this change is very small; the vibrating motor can also change the direction of the exciting force according to the installation method.

[0034] In the embodiment of the present application, the house body 10 is made of a 5 mm thick steel structure, and the house body 10 includes a top plate 11 and a side plate 12 arranged around the periphery of the top plate 11 and connected to the top plate 11. The bottom of the house body 10 is supported by a support structure 20 and is paved with a 5 mm thick steel plate. Specifically, the dimensions of the house body 10 are 6200 mm long, 2560 mm wide, and 2450 mm high. Of course, in other possible implementations, the length, width, and height of the house body 10 may also be other dimensions, and the present application does not limit the specific dimensions of the house body 10.

[0035] In addition, in the embodiment of the present application, the support structure 20 is composed of multiple 40 mm square tubes, so that the support structure 20 has greater strength. The support structure 20 can support the house body 10 to a certain height, thereby facilitating the setting of the collection structure 30 at the bottom of the house body 10, so that the sprayed material in the accommodating space falls into the collection structure 30 under the action of gravity.

[0036] In some embodiments, the sandblasting room further includes a dust removal system 40. The room body 10 is provided with a dust suction port 16 connected to the accommodating space. The dust removal system 40 is connected to the dust suction port 16. The dust removal system 40 is used to absorb dust in the accommodating space.

[0037] By directly connecting the room 10 to the dust removal system 40, it is ensured that the dust, debris, etc. generated during the sandblasting process can be immediately sucked into the dust removal system 40 through the dust suction port 16. This configuration greatly reduces the spread of dust in the working environment and helps to keep the sandblasting area clean and safe. Through the efficient dust removal system 40, not only the health of the staff is protected, but also the quality of the overall working environment is improved, which meets the multiple requirements of modern environmental protection and occupational health.

[0038] Furthermore, the dust removal system 40 includes a plurality of air collecting structures 41 with cavities and an air duct 42. The room body 10 is provided with a plurality of dust suction ports 16. Each air collecting structure 41 corresponds to each dust suction port 16. The cavity of the air collecting structure 41 is connected to the dust suction port 16. The air duct 42 has a circulation channel, which is connected to the cavity. The dust collected by each air collecting structure 41 can be taken away synchronously through the air duct 42, which can improve the dust removal efficiency. The provision of a plurality of air collecting structures 41 also increases the scope of dust removal, further improving the quality of the overall working environment.

[0039] It is understandable that multiple air collecting structures 41 can be arranged along the length direction of the house body 10, and multiple air collecting structures 41 are at the same height, thereby increasing the span of the dust removal system 40 and further increasing the dust removal range. Specifically, the dust removal system 40 of the embodiment of the present application includes three air collecting structures 41. Of course, in other possible implementations, the number of air collecting structures 41 can also be four, five, six or more. The present application does not limit the specific number of air collecting structures 41.

[0040] In the embodiment of the present application, the shape of the air collecting structure 41 is trumpet-shaped, that is, the size of the opening 15 of the air collecting structure 41 facing the room body 10 is larger than the opening 15 of the air collecting structure 41 away from the room body 10. Along the direction of the air duct 42 pointing to the room body 10, the radial size of the cavity of the air collecting structure 41 gradually decreases, thereby accelerating the rate of dust discharge and further improving the dust removal efficiency.

[0041] In addition, the opening 15 of the wind collecting structure 41 facing the room body 10 is provided with a mesh plate 411, the mesh hole diameter of the mesh plate 411 is 3 mm, the hole spacing is 5 mm, and the plate thickness of the mesh plate 411 is 5 mm.

[0042] In some embodiments, the hopper 31 includes an input port 311 and an output port 312 that are relatively arranged, the input port 311 is connected to the opening 15, and the hopper 31 also includes a valve plate 313 slidably arranged on the output port 312, and the valve plate 313 has a first state of opening the output port 312 and a second state of closing the output port 312.

[0043] When the valve plate 313 is in a closed state, the hopper 31 can collect the sand leaking downward from the room body 10. When the sand gradually fills the cavity of the hopper 31, the valve plate 313 can be opened, and the sand can be quickly discharged through the vibration motor and the valve plate 313 for recycling and reuse. This design not only facilitates daily operations, but also greatly improves resource utilization.

[0044] In some embodiments, the cross-sectional area of ​​the output port 312 is smaller than the cross-sectional area of ​​the input port 311, that is, the cross-sectional area of ​​the hopper 31 is V-shaped, and along the direction of gravity, the inner size of the cavity of the hopper 31 gradually decreases, so that the sand in the hopper 31 can flow downward along the inclined inner wall surface, thereby accelerating the flow rate of the sand in the hopper 31 and preventing sand from being retained.

[0045] In addition, in the embodiment of the present application, the shape of the output port 312 is a square, and the radial dimension of the output port 312 is 210 mm. Of course, in other possible implementations, the output port 312 may also be other shapes, and the output port 312 may also be other sizes. The present application does not limit the shape and size of the output port 312.

[0046] In some embodiments, the side wall of the room body 10 is also provided with an observation window 17 for observing the sandblasting situation in the room body 10. The observation window 17 and the sandblasting port 13 are arranged on the same side of the room body 10, so that the operator can observe the sandblasting situation in the room body 10 while performing the sandblasting process and adjust the operation in time.

[0047] Specifically, the observation window 17 and the sandblasting port 13 are arranged in front of the room body 10, and there are six observation windows 17, the size of which is 580 mm×370 mm, and the observation window 17 is installed with 5 mm thick glass, which can play a protective role.

[0048] In addition, two sandblasting ports 13 with a diameter of 200 mm are arranged below each observation window 17. The two sandblasting ports 13 are arranged on the left and right sides below the observation window 17 and are symmetrical to each other. The arrangement positions of the observation windows 17 and the sandblasting ports 13 are adapted to the human body structure, thereby increasing the convenience of the operator's operation. Of course, in other possible implementations, the number and size of the observation windows 17 and the sandblasting ports 13 are also set according to actual needs, and the present application does not make a sole limitation on the number and size of the observation windows 17 and the sandblasting ports 13.

[0049] In addition, the sandblasting port 13 is provided with a sandblasting glove 70, and the operator can put his hand into the glove to protect the operator's safety during the sandblasting process.

[0050] In some embodiments, a buffer for buffering the splash of spraying materials is attached to the inner wall of the room body 10. Specifically, the buffer is a 10 mm thick rubber, which can buffer the splash of corundum and the like, and the rubber can be attached to the inner wall of the room body 10 by gluing. This design not only protects the structure of the inner chamber of the room body 10, but also extends its service life. Through effective internal protection, it reduces the cost and time loss caused by frequent replacement and maintenance, and improves overall work efficiency.

[0051] In some embodiments, the sandblasting room further includes a rack 50 disposed in the accommodating space, the rack 50 is used to place multiple target workpieces 200, and the rack 50 is a multi-layer structure so that the multiple target workpieces 200 are located at different heights. Specifically, the rack 50 can be used to place the cathode bottom plate of the coating line and other long strips of objects.

[0052] In addition, an explosion-proof lamp is installed on the top of the chamber in the room body 10. When the explosion-proof lamp is turned on, it can provide sufficient lighting for operators, so that they can clearly see the target workpiece 200.

[0053] Specifically, explosion-proof lamps are installed at the four corners of the top of the chamber in the room body 10, so as to increase the range of lighting.

[0054] In some embodiments, the sandblasting room further includes a screen structure 60 disposed at the opening 15 . The screen structure 60 may be disposed on a steel plate, and the diameter of the screen holes of the screen structure 60 is 8 mm.

[0055] In some embodiments, a door panel 14 is further provided on the side of the room body 10, and the door panel 14 is rotatably connected to the side panel 12 via a rotating shaft 141. When sandblasting is required, the door panel 14 can be closed to ensure the airtightness of the room body 10. When the sandblasting is completed, the target space needs to be placed or replaced, or the interior of the room body 10 needs to be maintained, the door panel 14 can be opened.

[0056] Specifically, the free end of the door panel 14 is also connected to a clamping handle 142. When the door panel 14 is in a closed state, the door panel 14 can be locked by the clamping handle 142, and the operation is convenient and quick.

[0057] In addition, the sandblasting room further comprises a staircase 18, which is convenient for operators to climb up to a high place.

[0058] The present application also proposes a coating production line, which includes a sandblasting room. The specific structure of the sandblasting room refers to the above-mentioned embodiment. Since the coating production line adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0059] In summary, the sandblasting room provided by the present application, by setting the target workpiece 200 in the room body 10, the operator can spray the material to the target workpiece 200 in the room body 10 through the sandblasting port 13 outside the room body 10, and the dust generated by the sandblasting can be isolated, effectively ensuring the safety and health of the operator, and the sprayed material can be discharged outward through the hopper 31 under the action of gravity, and recycled and reused, thereby improving the resource utilization rate; in addition, the vibrator 32 can drive the hopper 31 to vibrate, thereby accelerating the discharge of the material through the hopper 31, thereby improving the efficiency of material recovery.
