Description

TECHNICAL FIELD

[0001] The present application relates to the field of dust removal production, and in particular to a casting sand mold spraying dust removal device. BACKGROUND

[0002] In the process of casting, the surface of the sand mold directly contacts with the metal liquid, and paint is usually sprayed on the surface of the sand mold to reduce the roughness of the surface, so as to reduce the production cost and improve the surface quality of the casting and reduce the inclusion of sand. There are many studies on the spraying of sand molds in China, such as patent document: a multi-head glue spraying device for sand mold casting (CN111283149A), which can realize uniform glue spraying on the surface of the sand mold through the multi-head glue spraying mechanism.

[0003] However, in the casting of train parts, the surface of the side frame and the casting sand mold is sprayed with a kind of aggregate, which causes great wear of the spray gun and the hose. The pressure and flow rate of the fluid vary during the spraying process, and it is not easy to achieve robot spraying. Moreover, the size of this type of sand mold is large, making it difficult to perform automatic spraying operations, and the operator needs to enter the spraying room to perform the spraying operation. In the field, the sand mold paint is sprayed on the surface of the sand mold by manual spraying with a spray gun. During the spraying operation, the paint atomizes and drifts, causing environmental pollution and harming the health of the workers.

[0004] Traditional dust removal technology is to set a fixed dust collection device at a predetermined position on one side or the top of the sprayed sand mold to adsorb dust. However, due to the large size of the side frame and the casting sand mold, in order to ensure that the operator can complete the spraying operation, the dust collection device cannot be set closely on both sides, and it is usually set at the top of the sand mold. However, the dust collection effect of the dust collection device set at the top is poor. Moreover, since the dust collection device is set at the top, the dust particles in the spraying process move upward from the head of the human body, and the operator needs to wear appropriate work clothes, but it still causes harm to the operator's body.

DETAILED DESCRIPTION

[0027] The application will be further described below in conjunction with the drawings and examples.

[0028] Reference Figures 1-7 A casting sand mold spraying dust removal device, comprising a spraying chamber 1, feeding openings 101 are opened on both sides of the spraying chamber 1, a feeding channel is formed between the two feeding openings 101, and a conveying assembly 102 is arranged in the spraying chamber 1, wherein the spraying part 2 is conveyed by the conveying assembly 102 to move directionally, after the spraying part 2 enters the spraying chamber 1, workers perform coating spraying work on the sand mold from both sides, and the spraying part 2 is the sand mold, and the spraying part 2 is used instead of the sand mold in the following description.

[0029] A dust suction device 3 is arranged in the spraying chamber 1, and the dust suction device 3 can absorb particulate matter generated in the coating spraying, so as to avoid that the particulate matter in the dust suction device 3 escapes to cause harm to the workers; wherein the dust suction device 3 comprises a dust collector 301, a dust suction channel 302 is opened in the dust collector 301, at least one dust suction port is opened in the side wall of the dust collector 301 and communicates with the dust suction channel 302, the dust suction port is arranged in a flat port shape, which can absorb the side wall of the spraying part 2 in all directions, wherein the dust collector 301 is connected with a negative pressure device, the negative pressure generated by the negative pressure device realizes the absorption of the particulate matter in the coating; the above-mentioned negative pressure device is connected with an electric pulse bag dust collector for collecting coating dust, the air suction speed is set to 15 m / s, the diameter of the air inlet pipe of the air suction port is 500 mm, 0.25*0.25*3.14*4*15*3600=42390 m3 / h, the air suction amount of the bag dust collector fan is greater than 50000 m3 / h, and the corresponding bag is matched.

[0030] The narrow dust suction port has consistent suction force at each position, and good dust suction effect, but the particulate matter in the aggregate is easily attached to the outside of the dust suction port, and needs to be cleaned regularly by manual. In order to solve the above problems, two cleaning rollers 303 are rotatably connected to the inner wall of the dust suction port, the two cleaning rollers 303 have a predetermined gap 3031 therebetween, the other side of the cleaning roller 303 abuts against the inner wall of the negative pressure port, and the two cleaning rollers 303 partially extend out of the dust suction port. During the dust suction process of the dust collector 301, the particulate matter is attached to the surface of the cleaning roller 303, and the periodic rotation of the cleaning roller 303 can rub against the inner wall of the dust collector 301 to remove the particulate matter attached to the surface of the cleaning roller 303.

[0031] The dust collector 301 is provided with an adjusting mount 5 outside, the adjusting mount 5 is rotatably connected to the outer wall of the dust collector 301, the first driving device 502 is fixedly connected to the side wall of the adjusting mount 5 to drive the rotation of the dust collector 301, and the second driving device 4 is mounted on the inner wall of the spraying chamber 1 to drive the linear movement of the adjusting mount 5. The second driving device 4 can drive the dust suction device 3 to move linearly through the adjusting mount 5, so that the dust suction device 3 moves to different positions to complete the dust removal work on the inner and outer sides of the sprayed part 2. The first driving device 502 can control the rotation of the dust suction device 3, so that the dust suction port at the top of the dust suction device 3 can correspond to the position at the upper end of the sprayed part 2, to realize the dust suction work on both sides of the sprayed part 2. Compared with the conventional fixed dust suction device 3, the dust suction device 3 is arranged to move to different positions, which can be adjusted according to the size of the sprayed part 2, to avoid the problem of poor dust suction effect caused by the conventional single-side dust suction, and to avoid the problem of difficulty in coating caused by double-side dust suction.

[0032] It should be noted that the dust suction device 3 is arranged to be inclined when moving to the inner side and the outer side, and is arranged to be inclined on one side of the sprayed part 2 to adsorb the particulate matter in the coating from the middle position. Unlike the conventional high-position dust suction port, the dust suction port is arranged to be low on one side, which can avoid the excessive upward floating of the particulate matter in the coating, and can protect the health of the workers to the greatest extent.

[0033] Since the dust suction port is flat, the dust suction area at the end of the dust suction port is limited. The dust suction port can be arranged in two groups or multiple groups, and the two groups or multiple groups of dust suction ports are arranged in parallel and extend in the length direction. The length of the dust suction port should correspond to the length of the sprayed part 2, so that the sprayed part 2 can be fully dusted. An inclined transition surface 3021 is arranged on the inner wall of the dust suction channel 302, and the two groups of transition surfaces 3021 are symmetrically arranged. The two groups of transition surfaces 3021 are provided with a negative pressure port in communication with the negative pressure equipment, and the negative pressure port is located in the middle position, so that the suction force of the dust suction port at each position is small, to ensure that the dust particles at each position are effectively adsorbed.

Through such a rotating arrangement, dust particles accumulated at the dust suction port and the cleaning roller 303 can be prevented from falling into the spraying part 2, and production accidents can be avoided. Through such a rotating arrangement, the dust collection device 3 can pass above the spraying part 2 at a lower attitude, and the dust collection device 3 can be closer to the surface of the spraying part 2 in the subsequent dust collection process, ensuring sufficient dust collection effect. Moreover, the lifting device is not needed for control, reducing the operation difficulty. It should be noted that when the dust collection device 3 is rotated to the inside or the outside, the final attitude is inclined arrangement, and the dust collection device 3 is inclined arranged above the spraying part 2 on the inside or the outside, which can be closest to the attitude of the spraying part 2 to adsorb the dust particles, ensuring the dust collection effect.

Since the driving block 7031 is located in the driving control groove and cooperates with the driving control groove, the power rotating roller 701 can be driven to rotate forward and reverse during the linear movement of the driving rod into the driving opening, so as to complete the driving process. The driving rod penetrates through the driving chamber and partially extends out, the driving rod is slidably connected with the outer wall of the dust collector 301, the inner wall of the adjusting mounting frame 5 is provided with a driving transition surface 501 matched with the driving rod, and the arc-shaped driving transition surface 501 can exert pressure on the driving rod during the movement of the driving rod through one side of the driving transition surface 501.

[0037] In the actual production process, the surface of the cleaning roller 303 needs to be sprayed for a period of time to produce relatively thick dust accumulation, and frequent cleaning process can accelerate the aging of related components and shorten the service life.
