Description

Technical Field

[0001] The utility model relates to the field of waste powder recovery, in particular to a safe waste powder collection system. Background Art

[0002] At present, traditional sprayed waste powder is generally directly recovered by a vacuum cleaner. However, when this waste powder is recovered, powder is generally raised on site, and this powder is harmful to both air and the human body. Secondly, the powder is prone to combustion during the process of collection and storage. Currently, a safety device is installed at the post-stage of recovery. The main function of the safety device is to prevent the powder from burning due to drying or other reasons. However, powder will still be caused during collection, mainly because the power of the fan used is generally large. If it is small, the waste powder cannot be recovered. Secondly, the on-site operation conditions cannot be detected in real time, especially the concentration of waste powder, the collection speed, and the on-site temperature, which are extremely likely to cause potential safety hazards.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment 1: Refer to Figure 1-7 , a safety type waste powder collection system, including a bracket 1, a collection box 2, an adjustment mechanism 3, an air outlet pipe 4, a dust reduction system 5, a blanking mechanism 6, a temperature sensor 7, a wind speed sensor 8, an ionic smoke sensor 9 and an explosion-proof controller 10. The collection box 2 is arranged on the upper part of the bracket 1. The adjustment mechanism 3 is arranged on one side of the collection box 2. One end of the adjustment mechanism 3 is connected to a collection fan through an air inlet pipe 11. The explosion-proof controller 10 is arranged on the other side of the collection box 2. The blanking mechanism 6 is arranged at the bottom of the collection box 2. The temperature sensor 7, the wind speed sensor 8 and the ionic smoke sensor 9 are respectively arranged at the top inside the collection box 2, and the temperature sensor 7, the wind speed sensor 8, the ionic smoke sensor 9 and the explosion-proof controller 10 are electrically connected.

[0025] The adjustment mechanism 3 includes a cabinet body 30, a partition plate 31, a bottom plate 32, a top plate 33, a rotating shaft 34, a wind deflector 35, a rotating gear 36, a rack 37, a driving gear 38, and a driving motor 39. The cabinet body 30 is installed on one side of the collection box 2, and the middle of the cabinet body 30 is divided into upper and lower parts by the partition plate 31. A plurality of round holes are opened on the bottom plate 32, each round hole is matched with the rotating shaft 34, and a wind deflector 35 is installed on each rotating shaft 34. The upper parts of the rotating shafts 34 all pass through the partition plate 31, and the parts passing through the partition plate 31 are all installed with rotating gears 36. A notch is also opened on the upper surface of the partition plate 31, and a rack 37 is fitted in the notch. The rack 37 is respectively matched with the rotating gears 36. The driving gear 38 is also matched with the rack 37, and the driving gear 38 is installed at the output end of the driving motor 39. The driving motor 39 is installed on the upper part of the top plate 32.

[0026] When it is necessary to reduce the feeding speed of the waste powder, as long as the driving motor 39 is used to drive the rack 37 to slide in the notch, the movement of the rack 37 will cause all the driving gears 36 engaged with it to rotate. In this way, the rotating shaft 32 will drive the wind deflector 35 to rotate. The change in the gap between the wind deflectors 35 is the main factor controlling the speed of the waste powder. The change in the gap between the wind deflectors 35 mainly depends on whether the rack 37 moves to the left or to the right, and the gap changes differently in different directions.

[0027] A handle 390 is further provided at the bottom of the bottom plate 32, which is convenient for replacing the internal wind deflector 35. The bottom plate 32 can be disassembled. That is, when waste powder accumulates inside the cabinet body 30, only the top plate 2 needs to be opened, and the nut between the driving gear 36 and the rotating shaft 34 is disconnected, then the internal wind deflector 35 can be taken out, and then the inside can be cleaned.

[0028] A filter 12 is further provided on the upper part of the collection box 2. A filter plate 13 is arranged inside the filter 12. The upper part of the filter 12 is communicated with the outside through an air outlet pipe 4. The filter plate 13 can be replaced at any time. The connection of the air outlet pipe 4 with the outside can prevent the internal pressure from being too high.

A connecting arm 53 is arranged on the inner wall of the collection box 2, and the connecting arm 53 is fixedly connected with the spray pipe 52. A control valve 51 is further arranged on the water inlet pipe 50, and the control valve 51 is electrically connected to the explosion-proof controller 10. The dust reduction system 5 can spray water intermittently on the waste powder during the collection process, secondly reduce the occurrence of dust flying, and secondly, when combustion occurs, the water can be pressurized through the control valve for fire extinguishing.

[0030] The blanking mechanism 6 includes a blanking hopper 60, a clamping groove 61, a moving plate 62, a fixing plate 63, a connecting plate 64 and an electric cylinder 65. The blanking hopper 60 is installed at the bottom of the collection box 2. A clamping groove 61 is opened at the bottom of the blanking hopper 60. The moving plate 62 is fitted in the clamping groove 61. Fixing plates 63 are respectively arranged on both sides of the blanking hopper 60. The electric cylinder 65 is fixed on each fixing plate 63. The telescopic end of the electric cylinder 65 is connected to the moving plate 62 through the connecting plate 64.

[0031] During blanking, just control the electric cylinder 65 to extend left and right, and the moving plate 62 in the clamping groove 61 can be taken out, so as to start blanking. In order to prevent blockage during the blanking process, a dispersion block 16 is also arranged inside. When not blanking, the dispersion block 16 is located inside the placement groove 14 and does not affect normal blanking.

[0032] A placement groove 14 is also opened inside the blanking hopper 60. A push-pull rod 15 is arranged at the other end of the blanking hopper 60. A dispersion block 16 is arranged at one end of the push-pull rod 15 extending into the blanking hopper 60.

[0033] An alarm 17 is also arranged on the top of the explosion-proof controller 10. The explosion-proof controller 10 detects the operation situation inside the collection box 2 in real time, feeds back in time according to the operation situation, and gives an alarm when there is a potential safety hazard.
