DETAILED DESCRIPTION

[0021] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0022] See also Figure 1 In this embodiment, a dust removal device for manufacturing hollow gangue bricks includes a dust removal box 1, a transport mechanism 2 and a through-hole dust removal mechanism 6. The dust removal box 1 is arranged at a section of the transport mechanism 2, and the transport mechanism 2 is arranged in the dust removal box 1. The transport mechanism 2 is used to transport hollow bricks 3. When the hollow bricks 3 enter the dust removal box 1, the finished products are dusted. The through-hole dust removal mechanism 6 is arranged in the dust removal box 1, and is used to clean and dust the inner wall of the through hole 31 of the hollow brick 3 specifically. The dust after dust removal is discharged from the outlet at the bottom of the dust removal box 1.

[0023] In this embodiment, the dust removal box 1 is a sealed box body, and two material ports 11 are provided on the side wall of the dust removal box 1 for the conveying mechanism 2 to pass through, and a barrier curtain 12 is fixedly installed on the upper end of the material port 11 to reduce the dust from overflowing from the material port 11. At least two fans 4 are fixedly installed on the inner top of the dust removal box 1, and the fans 4 generate downward airflow, so as to blow and remove dust from the hollow bricks 3 on the conveying mechanism 2 entering the dust removal box 1.

[0024] In order to specially clean the through hole 31 of the hollow brick 3, a through hole dust removal mechanism 6 is arranged in the dust removal box 1. The through hole dust removal mechanism 6 is arranged in the dust removal box 1 to move up and down, and the through hole dust removal mechanism 6 is arranged below the transportation mechanism 2. When the hollow brick 3 moves to a specific workstation directly above the through hole dust removal mechanism 6, the transportation mechanism 2 stops running, and the through hole dust removal mechanism 6 is shifted upward through the transportation mechanism 2 to the through hole 31, and the through hole 31 is cleaned.

[0025] In this embodiment, the transport mechanism 2 preferably uses conveying rollers 22, that is, multiple conveying rollers 22 are rotatably installed on the frame 21, and the conveying rollers 22 are arranged and distributed on the frame 21. There are intervals between the conveying rollers 22, which can facilitate the through-hole dust removal mechanism 6 to pass through.

[0026] In this embodiment, a mounting seat 13 is fixedly installed near the bottom of the dust removal box 1, a cylinder 14 is fixed on the mounting seat 13, and the through-hole dust removal mechanism 6 is fixed on the cylinder 14, and the through-hole dust removal mechanism 6 is driven by the cylinder 14 to move up and down.

[0027] See also Figure 2In this embodiment, specifically, the through-hole dust removal mechanism 6 includes a bracket 61, a bellows 62, a hollow shaft 63, an air pump 65 and a transmission device. The bracket 61 is fixed on the cylinder 14, and the bellows 62 is fixedly mounted on the bracket 61. The hollow shaft 63 is vertically arranged and rotatably mounted on the bellows 62 through a sealed bearing. A sweeping brush cloth 64 is fixed above the hollow shaft 63. A flow hole 66 for connecting to the bellows 62 is opened on the hollow shaft 63. The hollow shaft 63 is connected to the transmission device to drive it to rotate. An air pump 65 is arranged in the bellows 62, and an air outlet hole (not shown in the figure) is opened on the peripheral side of the hollow shaft 63. During operation, the cylinder 14 drives the bracket 61 to move upward, so that the bracket 61, the bellows 62 and the hollow shaft 63 move upward and pass through the gap between the conveying rollers 22 to move into the through hole 31 of the hollow brick 3. The transmission device drives the hollow shaft 63 to rotate, so that the sweeping cloth 64 sweeps the inner wall of the through hole 31, and cooperates with the airflow blown downward by the top fan 4, so that the dust on the surface of the hollow brick 3 and the inner wall of the through hole 31 can be completely removed. At the same time, in order to avoid the situation where the dust on the inner wall is not thoroughly cleaned, the pressurized airflow blown by the air pump 65 enters the hollow shaft 63 through the flow hole 66, and then blows toward the inner wall of the through hole 31 from the air outlet on the side wall, and cooperates with the cleaning function of the sweeping cloth 64, so that the inner wall of the through hole 31 is completely cleaned, greatly improving the cleaning effect.

[0028] In this embodiment, the number of the conveying rollers 22 is two, and may also be one or four, depending on the number of the through holes 31 in the hollow brick 3 .

[0029] In this embodiment, the transmission device includes a motor 67 and gears. The motor 67 is fixedly mounted on the bracket 61. A small gear 69 is fixedly mounted on the bottom of the hollow shaft 63. A large gear 68 is fixedly mounted on the transmission shaft of the motor 67. The large gear 68 meshes with the small gear 69 to realize the transmission of the hollow shaft 63.

[0030] The dust removal device in the manufacturing of the hollow gangue brick 3 of this embodiment is also provided with a position detection mechanism, which is used to detect whether the hollow brick 3 has reached a specific position above the through-hole dust removal mechanism 6, and control the start and stop of the transport mechanism 2. When the hollow brick 3 reaches the specific position, the transport mechanism 2 stops, and the through-hole dust removal mechanism 6 moves up to clean the through hole 31, and then moves down to reset after cleaning; on the contrary, when the hollow brick 3 has not reached the specific position, the transport mechanism 2 operates until the hollow brick 3 reaches the specific position.

[0031] Specifically, this embodiment is described by taking two hollow shafts 63 as an example. The position detection mechanism includes a signal transmitter, a signal receiver and a photoelectric ring 52a. There are three signal transmitters. The first signal transmitter 51, the second signal transmitter 52 and the third signal transmitter 53 are all fixedly installed on the top of the dust removal box 1. The first signal transmitter 51 and the third signal transmitter 53 correspond to the two hollow shafts 63 up and down. The first signal receiver 51a and the third signal receiver 53a are respectively fixed on the top of the two hollow shafts 63, thereby forming two groups of signal switches with the two signal transmitters respectively. The photoelectric ring 52a is fixedly mounted on the conveying roller 22 between the two hollow shafts 63. The second signal transmitter 52 corresponds to the photoelectric ring 52a up and down and forms a group of signal switches. The specific detection process is that when the hollow brick 3 moves to the specific position, the two through holes 31 thereon allow the signals of the first and third signal transmitters 53 to pass through, so that the first and third signal receivers 53a receive the signals, and the solid part between the two through holes 31 on the hollow brick 3 blocks the signal path between the photoelectric ring 52a and the second signal transmitter 52, so that the group of signal switches is disconnected, thereby realizing three-point linkage position detection, and the detection result is accurate, ensuring that the hollow brick 3 can accurately enter the specific position. Except for the above situation, it indicates that the hollow brick 3 has not entered the specific position, and the transportation mechanism 2 continues to operate.

[0032] Preferably, in this embodiment, a cyclone separation barrel 7 is further included, which is connected to the outlet at the bottom of the dust removal box 1 through a connecting pipe 15. The connecting pipe 15 is connected to the separation barrel along the tangential direction of the side wall of the cyclone separation barrel 7. An exhaust port 71 is arranged at the top of the cyclone separation barrel 7, and a dust outlet 72 is arranged at the bottom. The airflow blown out of the dust removal box 1 carries dust and is blown into the separation barrel along the tangential direction by the connecting pipe 15, and spirally settles along the inner wall of the separation barrel. The dust is discharged from the bottom dust outlet 72, and the airflow is discharged from the top exhaust port 71, so as to facilitate the centralized collection of dust.
