Description

Technical Field

[0001] This utility model relates to the technical field of suspended shot blasting machines, specifically a shot blasting machine for castings with built-in dust removal function. Background Technology

[0002] A suspended shot blasting machine is a highly efficient surface treatment device for castings. It uses a shot blaster to propel shot at high speed onto the surface of the casting, removing impurities and improving surface quality. During operation, the casting is suspended by a hook and enters the shot blasting machine chamber. The shot blaster rotates at high speed, propelling shot onto the casting surface to remove impurities such as oxide scale and rust. The shot and impurities are separated by a bottom separator, and the shot is then lifted and recycled by a screw conveyor.

[0003] When a shot blasting machine is in use, the shot is blasted at a high frequency and speed. The hook can drive the casting to rotate and perform multi-directional surface treatment on the casting. Therefore, a certain amount of dust will be generated during the process. When the door of the shot blasting machine is opened, there is still dust inside that has not settled. If workers work directly under these conditions, they will inevitably be affected by the dust, which is not conducive to the health and hygiene of the working environment and causes inconvenience to the work. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a casting shot blasting machine with built-in dust removal function, which solves the problem of dust generated during the operation of existing casting shot blasting machines causing inconvenience to workers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A shot blasting machine for castings with built-in dust removal function includes a shot blasting machine housing and a control cabinet. The top two sides of the shot blasting machine housing are respectively connected to an air inlet pipe and an air outlet pipe. An electric push rod is installed on the top of the shot blasting machine housing at the position corresponding to the air inlet pipe. The lower end of the piston rod of the electric push rod is fixed with a cover corresponding to the position of the air inlet pipe.

[0007] The exhaust pipe is connected to an induced draft fan via a connecting pipe, and a diamond mesh is installed between the connecting pipe and the exhaust pipe. The air outlet of the induced draft fan is connected to a long cylindrical filter bag. Multiple cylindrical limiting cages are fixed on one side of the shot blasting machine box, and the long cylindrical filter bag is inserted into the limiting cage in an S-shape.

[0008] Preferably, the air inlet pipe and the air outlet pipe are respectively located at diagonal positions on the top of the shot blasting machine housing.

[0009] Preferably, the connecting pipe is a large circular arc bend pipe.

[0010] Preferably, the induced draft fan is fixed to the upper side of the shot blasting machine box via a mounting bracket fixed to the top side of the shot blasting machine box, and the induced draft fan and the long filter bag are located in the same vertical plane.

[0011] Preferably, the plurality of limiting cages are parallel to each other and the limiting cages are arranged vertically.

[0012] Preferably, the limiting cage is fixed on the side of the shot blasting machine housing away from the control cabinet.

[0013] Preferably, the long filter bag is tied to the air outlet of the blower using a slip-on stainless steel cable tie.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention, by setting up an air inlet pipe and an air outlet pipe, allows for dust removal after shot blasting. Air is introduced through the air inlet pipe and drawn in by the induced draft fan, drawing dust and air from inside the shot blasting machine chamber into a long cylindrical filter bag for dust removal. When the chamber door is then opened, the internal dust has been removed, thus improving working conditions and providing convenience for users. This solves the problem of dust generation during the operation of existing casting shot blasting machines causing inconvenience to workers. Attached Figure Description

[0020] 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.

[0021] like Figure 1-3As shown, this utility model provides a technical solution: a shot blasting machine for castings with built-in dust removal function, including a shot blasting machine box 1 and a control cabinet 2. The top two sides of the shot blasting machine box 1 are respectively connected to an air inlet pipe 3 and an air outlet pipe 4. The air inlet pipe 3 and the air outlet pipe 4 are respectively set at diagonal positions on the top of the shot blasting machine box 1, which helps the air to circulate and remove internal dust. An electric push rod 5 is installed on the top of the shot blasting machine box 1 at the position corresponding to the air inlet pipe 3. The lower end of the piston rod of the electric push rod 5 is fixed with a cover 6 corresponding to the position of the air inlet pipe 3.

[0022] The exhaust pipe 4 is connected to the induced draft fan 8 through the connecting pipe 7. The connecting pipe 7 is a large arc bend, and a diamond mesh 9 is installed between the connecting pipe 7 and the exhaust pipe 4. The air outlet of the induced draft fan 8 is connected to a long filter bag 10. The long filter bag 10 is tied to the air outlet of the induced draft fan 8 with a slip-on stainless steel cable tie 13 for easy disassembly, cleaning and replacement. The induced draft fan 8 is fixed to the upper side of the shot blasting machine box 1 through the mounting bracket 12 fixed to the top side of the shot blasting machine box 1. The induced draft fan 8 and the long filter bag 10 are located in the same vertical plane to reduce air resistance.

[0023] Multiple cylindrical limiting cages 11 are fixed on one side of the shot blasting machine housing 1. The limiting cages 11 are fixed on the side of the shot blasting machine housing 1 away from the control cabinet 2. The long filter bags 10 are inserted into the limiting cages 11 in an S-shape. The multiple limiting cages 11 are parallel to each other and the limiting cages 11 are set vertically, so that most of the long filter bags 10 are in a vertical state, which facilitates dust settling.

[0024] Working principle:

[0025] After shot blasting, without opening the door of the shot blasting machine chamber 1, the electric push rod 5 moves the cover 6 upward to open the air inlet pipe 3. The induced draft fan 8 drives the air inside the shot blasting machine chamber 1 to flow into the long filter bag 10. The air mixed with dust enters the long filter bag 10 and is filtered to remove dust. The electric push rod 5 moves the cover 6 downward to seal the air inlet pipe 3. The induced draft fan 8 is turned off to stop dust removal. Then the door of the shot blasting machine chamber 1 can be opened to take out and put in the castings. The long filter bag 10 is conveniently cleaned of internal dust regularly with the slip-on stainless steel cable ties 13.
