DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 , the utility model provides a technical solution:

[0023] In the present technical solution, a refractory material production screening device includes a screening machine 1, a screening mechanism 2 is movably installed in the inner cavity of the screening machine 1, and a dust removal mechanism 3 is installed on the side wall of the inner cavity of the screening machine 1, and the dust removal mechanism 3 is arranged above the screening mechanism 2;

[0024] The dust removal mechanism 3 includes a fixed sleeve 31, a dust suction pipe 32, a dust collecting bag 33, a filter plate 34 and a fan 35. The fixed sleeve 31 is installed on the upper wall of the inner cavity of the screening machine 1, the dust suction pipe 32 is inserted and installed in the fixed sleeve 31, and the end of the dust suction pipe 32 is sleeved with the dust collecting bag 33. The fan 35 is inserted and installed on the lower wall of the screening machine 1. The fan 35 is electrically connected to an external power supply. The input end of the fan 35 passes through the lower wall of the screening machine 1 and is installed with a filter plate 34. The filter plate 34 is fitted on the lower wall of the dust collecting bag 33.

[0025] A cleaning mechanism 6 is installed in the dust suction tube 32. The cleaning mechanism 6 includes an insertion rod 61, a scraper 62 and a rubber ring 63. A mounting hole 7 is opened on the side wall of the dust suction tube 32. The insertion rod 61 is inserted and installed in the mounting hole 7. A scraper 62 is installed at one end of the insertion rod 61 located in the dust suction tube 32. The scraper 62 can fit the inner wall of the dust suction tube 32. A rubber ring 63 is sleeved on the outer side of the insertion rod 61 and can be inserted into the mounting hole 7.

[0026] In this technical solution, the fan 35 in the dust removal mechanism 3 generates suction, so that the dust generated by the screening mechanism 2 when screening the refractory material is sucked into the dust collection bag 33 through the dust suction pipe 23, thereby preventing the dust from escaping to the outside of the screening machine and affecting the external working environment;

[0027] After the dust suction pipe 32 has been used for a period of time, it is easy to get clogged due to the accumulation of dust inside. In order to avoid affecting the absorption of smoke and dust, the device is equipped with a cleaning mechanism 6 in the dust suction pipe 32. When the dust suction pipe 32 needs to be cleaned, it is only necessary to pull the insertion rod 61 to clean the inner wall of the dust suction pipe 32 through the scraper 62, which is very convenient.

[0028] In some technical solutions, the screening mechanism 2 includes a screening box 21, a connecting plate 22, a spring 23, a fixed plate 24 and a vibration motor 25. A feed hopper 5 is inserted into the upper wall of the screening machine 1, and the discharge end of the feed hopper 5 is arranged above the screening box 21. The left and right side walls of the screening box 21 are both installed with connecting plates 22, and one end of the spring 23 is installed on the lower wall of the connecting plate 22. A fixed plate 24 is installed on the inner wall of the screening machine 1, and the other end of the spring 23 is installed on the upper wall of the fixed plate 24. A vibration motor 25 is installed on the lower wall of the screening box 21, and the vibration motor 25 is electrically connected to an external power supply.

[0029] In this technical solution, the refractory material falls onto the screen 10 in the screening box 21 through the feed hopper 5. After being energized, the vibration motor 25 can drive the screening box 21 to vibrate in the screening machine 1, thereby improving the screening efficiency of the screen 10 for the refractory material.

[0030] In some technical solutions, the dust suction pipe 32 is arranged above the screening mechanism 2, and a through hole 4 is opened on the side wall of the dust suction pipe 32.

[0031] In this technical solution, a plurality of through holes 4 are provided, and the dust generated in the screening machine 1 enters the dust suction pipe 32 through the through holes 4 and then enters the dust collecting bag 33 through the dust suction pipe 32 .

[0032] In some technical solutions, the inner cavity of the screening box 21 is installed with a driving roller 8 and a driven roller 9, and the outer sides of the driving roller 8 and the driven roller 9 are sleeved with a screen 10. The driving roller 8 is connected to an external motor. The inner wall of the screening box 21 is installed with a cleaning brush 11, and the cleaning brush 11 is in contact with the lower wall of the screen 10. The side wall of the screening box 21 is inserted with a first discharge chute plate 12 and a second discharge chute plate 13. The first discharge chute plate 12 is arranged between the driving roller 8 and the driven roller 9, and the second discharge chute plate 13 is in contact with the upper wall of the screen 10. The first discharge chute plate 12 and the second discharge chute plate 13 both pass through the side wall of the screening machine 1.

[0033] In this technical solution, the refractory material discharged by the first discharge chute plate 12 is the fine material screened out, and the refractory material discharged by the second discharge chute plate 12 is the coarse material screened out. This part of the coarse material needs to be further processed before it can be used.

[0034] The driving roller 8, the driven roller 9 and the screen 10 form a structure similar to a conveyor belt. In this device, the moving direction of the screen 10 is opposite to the direction in which the refractory material rolls on the screen 10, which increases the time the refractory material stays on the screen 10, thereby avoiding the occurrence of incomplete screening.

[0035] A cleaning brush 11 is also provided in the screening box 21, so that the screen 10 can be cleaned to prevent the screen 10 from being blocked. The dust suction pipe 32 is also provided with a through hole 4 on one side below the screening box 21, so that the refractory particles brushed off by the cleaning brush 11 can be sucked into the dust collecting bag 33.

[0036] In some technical solutions, rubber plates 14 are fitted on both the front and rear side walls of the screening box 21 , and the rubber plates 14 can fit together with the inner wall of the screening machine 1 .

[0037] In this technical solution, the rubber sheet 14 can prevent the screening box 21 from colliding with the inner wall of the screening machine 1, thereby protecting the screening box 21 and reducing noise.

[0038] In some technical solutions, a clearance groove 15 is opened on the side wall of the screening machine 1. There are two clearance grooves 15. The first discharge chute plate 12 and the second discharge chute plate 13 pass through the side wall of the screening machine 1 through the two clearance grooves 15 respectively. The side walls of the two clearance grooves 15 are both installed with a shielding curtain 16.

[0039] In this technical solution, the shielding curtain 16 prevents smoke and dust generated in the screening machine 1 from escaping without affecting the discharge of materials.

[0040] Working principle: Start the vibration motor 25 and the fan 35, and put the refractory material into the screen 10 in the screening box 21 through the feed hopper 5. After the vibration motor 25 is powered on, it can drive the screening box 21 to vibrate in the screening machine 1, thereby improving the screening efficiency of the screen 10 for the refractory material. The fine refractory material screened out will fall onto the first discharge chute plate 12 and then be discharged from the screening machine 1. The coarse refractory material screened out will fall onto the second discharge chute plate 13 and then be discharged from the screening machine 1.

[0041] At the same time, the fan 35 generates suction, so that it sucks the smoke and dust generated by the screening mechanism 2 when screening the refractory material into the dust collecting bag 33 through the dust suction pipe 23, thereby preventing the smoke and dust from escaping to the outside of the screening machine and affecting the external working environment.
