Description

Technical Field

[0001] This utility model belongs to the field of shot blasting equipment, specifically relating to a dust removal device for shot blasting machines. Background Technology

[0002] Shot blasting machines are casting equipment that uses high-speed shot to clean or strengthen the surface of castings. They can perform sand removal, core removal, and cleaning of castings. Shot blasting machines generate a large amount of dust during operation, requiring corresponding dust collection equipment for air filtration and purification. The dust collection device of a shot blasting machine generally uses dust filter plates for air filtration. However, these filter plates need to be cleaned regularly; otherwise, impurities will clog the filter screen, affecting the air filtration effect. Traditional filter plate cleaning requires manual opening and removal of the filter plate. While some existing dust collection devices are equipped with cleaning mechanisms, the cleaning effect of these mechanisms is poor and cannot effectively remove impurities from the filter plates.

This device can effectively filter and clean the smoke and dust during shot blasting operation, and can effectively clean and collect impurities on the filter plate, thereby improving the dust filtration effect.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dust removal device for a shot blasting machine includes a dust collection box and filter plates. The dust collection box has an inlet chamber, a connecting chamber, and an outlet chamber arranged vertically side-by-side from left to right. The bottom of the inlet chamber is connected to the bottom left side of the connecting chamber, and the top right side of the connecting chamber is connected to the top of the outlet chamber.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0023] like Figure 1-4 As shown, this utility model proposes a dust removal device for a shot blasting machine, including a dust collection box 1 and a filter plate 7. The dust collection box 1 has an air inlet chamber 101, a connecting chamber 102, and an air outlet chamber 103 arranged vertically side-by-side from left to right. The lower part of the air inlet chamber 101 is connected to the bottom left side of the connecting chamber 102, and the upper right side of the connecting chamber 102 is connected to the upper part of the air outlet chamber 103. An air inlet 11 is provided on the upper side wall of the air inlet chamber 101, and the air inlet 11 is connected to the air outlet of a suction fan 2 outside the dust collection box 1. The air inlet of the suction fan 2 is connected to the shot blasting machine. The exhaust vents of the machine are connected; an exhaust port 12 is provided at the bottom of the exhaust chamber 103, and an exhaust fan 5 is installed outside the dust collection box 1 at the exhaust port 12; dust filter plates 7 are symmetrically installed below the air inlet chamber 101 and the air outlet chamber 103 respectively, and dust discharge ports 13 are provided on the left and right sides of the dust collection box 1 at positions corresponding to the dust filter plates 7, and a dust collection box 4 is installed at the dust discharge ports 13; a cleaning brush 6 is movably provided on the dust filter plate 7, and the drive mechanism inside the dust collection box 1 is connected to the cleaning brush 6 to drive the cleaning brush 6 to move left and right to clean the dust on the dust filter plate 7.

[0024] The fumes generated during the operation of the shot blasting machine are sent into the air inlet chamber 101 through the air inlet 11 by the suction fan 2. After being filtered for the first time by the dust filter plate 7 in the air inlet chamber 101, the fumes enter the air outlet chamber 103 in a zigzag pattern through the connecting chamber 102. After being filtered for the second time by the dust filter plate 7 in the air outlet chamber 103, the filtered air is discharged into the dust collector box 1 through the air outlet 12 below by the exhaust fan 5. This application uses two dust filter plates 7 to effectively filter the fumes, significantly improving filtration efficiency and quality.

[0025] The dust filter plates 7 in the air inlet chamber 101 and the air outlet chamber 103 are respectively inclined downwards on both sides, forming an "eight" shape. Dust discharge ports 13 are opened on the left and right sides of the dust collection box 1 at positions corresponding to the dust filter plates 7, and dust collection boxes are installed at the dust discharge ports 13. Furthermore, a cleaning port is opened on the side of the dust collection box 4, and a sealed door 41 is installed at the cleaning port. By opening the sealed door 41, the impurities and dust collected in the dust collection box 4 can be centrally cleaned, facilitating the dust cleaning operation of this application. Moreover, the inclined arrangement of the dust filter plates 7 on both sides further facilitates the discharge of impurities filtered down from above into the dust collection boxes 4 on both sides, making the cleaning and collection of impurities more efficient.

[0026] In addition, connecting seats 73 are provided at both ends of the dust filter plate 7. The connecting seats 73 are detachably fixed in the dust collection box 1 by bolt structure. The connecting seats 73 are fixed in the dust collection box 1 by bolt structure on both sides of the dust filter plate 7, which makes the disassembly and installation of the dust filter plate 7 more convenient and more conducive to the regular maintenance and replacement of the dust filter plate 7.

[0027] A cleaning brush 6 is movably mounted on the dust filter plate 7. The drive mechanism inside the dust collection box 1 is connected to the cleaning brush 6 and is used to drive the cleaning brush 6 to move left and right to clean the dust on the dust filter plate 7. The drive mechanism includes a housing 3, a connecting rod 35, a vertical rod 34, a moving block 33, a crank 32, and a motor 31. The housing 3 is installed on the top of the dust collection box 1. The motor 31 is horizontally installed on the housing 3. The output shaft 311 of the motor 31 is vertically fixed to one end of the crank 32, which is set in the vertical direction. The other end of the crank 32 is horizontally fixed to a rotating shaft 321. The top of the air inlet chamber 101 and the air outlet chamber 103 are both provided with through holes 14. The corresponding vertical rods 34 are vertically slidably inserted through the through holes 14. The upper ends of the two vertical rods 34 are fixed to the moving block 33. The moving block 33 is horizontally provided with a sliding groove 711. The rotating shaft 321 is slidably locked in the sliding groove 711. The lower ends of the two vertical rods 34 are respectively rotatably connected to the upper ends of the corresponding connecting rods 35. The lower ends of the connecting rods 35 are inclined and rotatably connected to the corresponding cleaning brushes 6. The cleaning brushes 6 are slidably installed on the dust filter plate 7.

[0028] When the crank 32 driven by the motor 31 rotates in the vertical plane, the rotating shaft 321 slides in the groove 711 in the moving block 33, which can drive the moving block 33 to move up and down reciprocally. This, in turn, drives the two vertical rods 34 to move up and down in the through hole 14, which can drive the two connecting rods 35 to rotate and swing back and forth. This allows the connecting rods 35 to pull the cleaning brush 6 slidably installed on the dust filter plate 7 to move back and forth left and right, thereby effectively cleaning the impurities on the dust filter plate 7 and significantly improving the dust filtration efficiency of this application.

[0029] The dust filter plate 7 includes a mesh plate 72 and two frames 71. The mesh plate 72 is located in the middle, and the two frames 71 are fixed to the front and rear edges of the mesh plate 72. A groove 711 is formed along the length of each frame 71. The cleaning brush 6 is perpendicular to the two frames 71, and sliders 61 are fixed to its lower sides. The two sliders 61 are slidably engaged in the corresponding grooves 711. A connecting seat 73 is fixedly installed on the frame 71. In a specific implementation, the groove 711 can be designed as a T-shaped groove, and the sliders 61 can be T-shaped blocks that cooperate with the groove 711.

[0030] The frame structure 71 provided at the front and rear of this application can significantly improve the structural strength of the dust filter plate 7. The sliding groove 711 opened on its upper part can provide limiting guidance for the movement of the cleaning brush 6 by cooperating with the slider 61, thereby improving the movement stability of the cleaning brush 6.

[0031] When using this invention, under the action of the suction fan 2 and the exhaust fan 5, the fumes generated during the shot blasting operation enter the dust collection box 1 through the air inlet 11, pass through the air inlet chamber 101, the connecting chamber 102 and the air outlet chamber 103, and are then discharged from the dust collection box 1 through the air outlet 12. During this process, the air follows a zigzag path in the dust collection box 1, passing through two dust filter plates 7 for effective air purification and filtration. Impurities in the air adhere to the upper surface of the two dust filter plates 7. The motor 31 drives the crank 32, the moving block 33, the two vertical rods 34 and the two connecting rods 35 to reciprocate, thereby causing the cleaning brush 6 to move back and forth above the dust filter plates 7, effectively cleaning the impurities on the dust filter plates 7. The swept impurities and dust are sent into the dust collection box 4 through the dust discharge ports 13 on both sides, significantly improving the dust filtration efficiency of this application.
