Description

Technical Field

[0001] The utility model relates to the technical field of powder recovery, in particular to a powder recovery device for producing flame-retardant extruded boards. Background Art

[0002] At present, in the production process of extruded polystyrene board, operations such as embossing and grooving are required, and some powder and block waste will be generated in the process, which need to be collected and cleaned in time to avoid affecting the processing environment. At the same time, recycling can save production costs. For example, the patent with publication number CN214391451U discloses a powder recovery device for extruded polystyrene board production, including a frame, a curved pipe is provided at the upper end of the frame, a conveying platform is provided under the curved pipe, a transverse pipe is connected to the upper end of the curved pipe, a blower is provided at the end of the transverse pipe away from the curved pipe, a first filter is provided in the middle of the transverse pipe, a second filter is provided between the first filter and the blower, and a first recovery is connected in the middle of the transverse pipe. The blower rotates forward to exhaust air, and the waste is sucked into the bent pipe from the lower end of the bent pipe and then enters the horizontal pipe. The block waste is blocked by the first filter and falls into the first recovery trough, and the powdery waste passes through the first filter to the second filter. The mesh diameter of the second filter is smaller, and the powdery waste is blocked by the second filter and falls into the second recovery trough, and the powdery waste is collected separately from the block waste, and the powdery waste is directly recycled. However, since the horizontal pipe is constantly exhausting air, the horizontal pipe is in a negative pressure state, making it difficult for the lighter powder in the horizontal pipe to fall off, resulting in the accumulation of powder in the horizontal pipe, causing the horizontal pipe to be blocked, affecting the strength of the exhaust, and thus affecting the recovery of the powder.

[0003] To this end, the utility model provides a powder recovery device for producing flame-retardant extruded boards. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a powder recovery device for the production of flame-retardant extruded boards, comprising an air duct 1, a suction head 2 is fixed at one end of the air duct 1, an exhaust fan is fixed at the other end of the air duct 1, a first material discharge channel 3 and two connecting channels 17 are fixed on the air duct 1, a second material discharge channel 4 is fixed on the lower side of the connecting channel 17, a filter screen 9 and a dustproof screen 10 are fixed in the air duct 1, a static electricity elimination rod 11 is installed in the air duct 1, the static electricity elimination rod 11 is in contact with the filter screen 9, a collection box 18 is slidably matched in the air duct 1, and the collection box 18 corresponds to the connecting channel 17.

[0022] In this embodiment, the air duct 1 is connected to the first material discharge channel 3, a crushing roller 8 is rotatably arranged in the first material discharge channel 3, a motor 7 is fixed to one side of the first material discharge channel 3, and an output end of the motor 7 is fixedly connected to the crushing roller 8.

[0023] Specifically, larger pieces of extruded board waste are sucked into the air duct 1 and then blocked by the filter 9. At this time, the larger pieces of extruded board waste fall into the first discharge channel 3 by their own gravity, and then the motor 7 is started, so that the motor 7 drives the crushing roller 8 to rotate, thereby breaking up the larger pieces of extruded board waste, which is convenient for recycling.

[0024] A slide groove 14 is provided in the air duct 1, and a slider 15 is slidably fitted in the slide groove 14. A baffle 13 is installed between the slider 15 and the static elimination rod 11. The baffle 13 is rotatably connected to the static elimination rod 11 and the slider 15. An electric cylinder 12 is fixed on the air duct 1, and the output end of the electric cylinder 12 is fixedly connected to the static elimination rod 11.

[0025] Specifically, when it is necessary to clean the dust on the filter 9, the electric cylinder 12 is started, so that the electric cylinder 12 drives the static elimination rod 11 to slide downward, thereby pushing the dust into the first feeding channel 3, and the static elimination rod 11 will also drive the baffle 13 to move when it moves, so that the baffle 13 blocks the air duct 1, thereby preventing the scraped dust from falling naturally.

[0026] The connecting channel 17 is connected to the air duct 1. The two connecting channels 17 are respectively located on both sides of the air duct 1. Half of the collecting box 18 is located in the connecting channel 17. The collecting box 18 is an M-shaped structure. Push-pull rods 19 are fixed on both sides of the collecting box 18. The push-pull rods 19 are slidably connected to the connecting channel 17.

[0027] Specifically, when there is a lot of dust in the collection box 18 located in the air duct 1, the push-pull rod 19 can be pulled manually to drive the collection box 18 to move, thereby sending the collection box 18 located in the air duct 1 to the connecting channel 17. At this time, the other half of the collection box 18 will enter the air duct 1 to collect dust, and the dust in the collection box 18 in the connecting channel 17 can naturally fall into the second discharge channel 4, thereby facilitating the collection of dust.

[0028] The connecting channel 17 is connected to the second material discharge channel 4, a collecting channel 5 is installed at the lower side of the air duct 1, the collecting channel 5 is fixedly connected to the second material discharge channel 4 and the first material discharge channel 3, the collecting channel 5 is connected to the second material discharge channel 4 and the first material discharge channel 3, a discharge channel 6 is fixed at the lower side of the collecting channel 5, and the discharge channel 6 is connected to the collecting channel 5.

[0029] Specifically, the dust enters the connecting channel 17 through the first material discharge channel 3 and the second material discharge channel 4, and then the dust can be recovered through the discharge channel 6, thereby preventing the dust from polluting the production environment and reducing production costs.
