Description

TECHNICAL FIELD

[0001] The present application relates to the field of comprehensive pollution control technology, and particularly relates to a circulating filter dust removal device with dust suppression function. BACKGROUND

[0002] In the construction, the core of carrying out comprehensive pollution control operation is to strictly control the dust generated in the construction process, so as to reduce the concentration of air suspended particles, protect the health of the operation personnel and reduce the load of the surrounding environment. The dust removal device as an efficient local cleaning device on site can immediately suck, recover and close process the dust, stone blocks and metal pieces such as iron nails and screws generated in the operation, so as to optimize the operation environment and reduce the hidden danger of respiratory system occupational diseases.

[0003] However, the existing dust removal device will collect various waste such as dust after adsorption, and some recyclable metal pieces and sandstone fragments are mixed together and difficult to distinguish, resulting in resource waste. Subsequent manual separation leads to high cost. In addition, some existing dust removal devices are difficult to clean the filter screen, so that the filter screen is difficult to recycle. SUMMARY

[0004] The present application aims to provide a circulating filter dust removal device with dust suppression function to solve the problems in the prior art.

[0006] The dust removal device is provided with a control system capable of controlling the whole device.

[0007] The operation control system controls the dust removal device to move in the area to be cleaned through the sliding chassis. The negative pressure motor is started, and the output shaft of the negative pressure motor drives the fan to rotate. The fan drives air to pass through the discharge port of the sliding chassis, and the air in the fan shell is discharged to form a negative pressure. Then the air in the dust collection bin is sucked into the fan through the air suction pipe. The negative pressure is generated in the dust collection bin, and the external air is sucked into the dust collection bin through the dust suction pipe and the dust hopper. Thus, the dust hopper generates a negative pressure suction force, and the dust hopper sucks the waste on the ground. The waste sucked is guided into the semi-rigid filter screen along the dust suction pipe. Part of the dust mixed in the air is filtered by the dustproof filter screen. The dust removal device moves in the area to suck dust until all the waste in the area is cleaned, so as to achieve the effect of inhibiting dust raising.

[0008] After cleaning, the control system controls the negative pressure motor to rotate reversely. The negative pressure motor drives air to blow reversely to the dustproof filter screen through the fan, so that the dust adhered to the dustproof filter screen is blown down reversely, thereby realizing self-cleaning of the filter screen and ensuring that the filter screen can be used cyclically.

[0063] After the area is cleaned, the control system starts the separation motor 83, the output shaft of the separation motor 83 drives the main shaft 85 to rotate, the threaded segment 854 on the main shaft 85 rotates, since the threaded slider 873 is threadedly connected with the threaded segment 854, and the threaded slider 873 is embedded with the limiting strip 876, it can only slide up and down in the vibration lifting cylinder 87, under the action of the thread rotation, the threaded slider 873 starts to slide upwards, at this time, the sliding head 871 on the vibration lifting cylinder 87 is blocked by the vibration baffle 853, so that the vibration lifting cylinder 87 cannot move upwards, the threaded slider 873 moves upwards and squeezes the vibration spring 874 between the two, until the vibration spring 874 is completely compressed, then the threaded slider 873 rises and directly drives the vibration lifting cylinder 87 upwards through the completely compressed vibration spring 874, as the upward driving force gradually increases, the squeezing force between the vibration baffle 853 and the sliding head 871 increases, when the squeezing force exceeds the critical value, the sliding head 871 overcomes the elastic force of the compression spring 872, retracts into the vibration lifting cylinder 87 and slides upwards through the vibration baffle 853, then the vibration spring 874 rebounds quickly and drives the vibration lifting cylinder 87 to move upwards quickly, after the sliding head 871 slides through the vibration baffle 853, the compression spring 872 drives the sliding head 871 to pop out, the popped-out sliding head 871 moves upwards quickly with the vibration lifting cylinder 87 and collides with the vibration baffle 853 above, the vibration generated by the collision is transmitted to the vibration lifting cylinder 87 by the sliding head 871, the vibration lifting cylinder 87 drives the semi-rigid filter screen 82 to vibrate, the waste material in the semi-rigid filter screen 82 is subjected to vibration, so that the dust and tiny particles mixed in the large-particle waste material are further shaken off, improving the screening effect.

[0064] In this way, the main shaft 85 continues to rotate, the threaded slider 873 continues to rise, and the sliding head 871 generates vibration with the vibration baffles 853 one by one from bottom to top, so that the semi-rigid filter screen 82 generates intermittent multi-level vibration, at the same time, the vibration lifting cylinder 87 gradually rises, the vibration lifting cylinder 87 drives the semi-rigid filter screen 82 to continuously lift the bottom of the semi-rigid filter screen 82, so that the semi-rigid filter screen 82 gradually changes from concave to convex, accompanied by vibration, at this time, the large-particle waste material on the semi-rigid filter screen 82 starts to slide outward along the convex surface, the metal collectors 84 are arranged around the semi-rigid filter screen 82, when the metal parts mixed in the waste material pass through the adsorption strips 8411, they are adsorbed by the bar magnets 8413 therein, the remaining large-particle waste material further falls on the filter plate 815, the impurities and tiny particles remaining on the large-particle waste material pass through the holes of the filter plate 815 and fall into the bottom of the housing 81, together with the impurities collected before; the large-particle waste material is concentrated, which is convenient for recycling the gravel in the large-particle waste material.

[0065] When the threaded slider 873 rises to the top of the threaded section 854, enters the smooth section 855, the vibration spring 874 is in a compressed state, the threaded slider 873 remains at the current height after losing the threaded effect and no longer continues to rise, at this time, the vibration lifting cylinder 87 also no longer rises, since the transmission connecting piece 86 is rotationally connected with the vibration lifting cylinder 87, when the vibration lifting cylinder 87 rises, it synchronously drives the transmission connecting piece 86 to rise, when the transmission connecting piece 86 rises, the transmission cylinder 861 slides on the reinforcing shaft 851 and always remains without being separated from the reinforcing shaft 851, the reinforcing shaft 851 drives the transmission cylinder 861 to continuously rotate through the transmission bar 852, so that when the transmission connecting piece 86 rises, it can still rotate, when the transmission connecting piece 86 rises to a certain height, the transmission ring 862 begins to contact the turntable 88, the tooth groove 863 and the transmission tooth 883 gradually mesh transmission, when the vibration lifting cylinder 87 is at the highest position, the transmission ring 862 is fully engaged with the turntable 88, the transmission ring 862 drives the turntable 88 to rotate, the turntable 88 extrudes the transmission column 8425 through the arc-shaped groove 881, the transmission column 8425 is extruded to drive the blanking piece 842 to slide along the suction member 841, the blanking plate 8421 slides away from the blanking hole 812 in the direction of the metal collecting cavity 814, the blanking plate 8423 slides out of the blanking hole 813, as the blanking plate 8423 slides on the suction strip 8411, the metal pieces adsorbed on the suction strip 8411 are gradually pushed by the blanking plate 8423 to the blanking hole 812, when the blanking plate 8423 is displaced to the position of the blanking hole 812, the metal pieces on the suction strip 8411 are all pushed away from the suction strip 8411, and finally fall into the metal collecting cavity 814 to be collected, so as to realize the purpose of separating and classifying the waste materials.

[0066] After the classification is completed, the control system controls the separation motor 83 to rotate reversely, under the pushing force of the compression spring 872, the threaded slider 873 is quickly screwed with the threaded section 854, and drives the vibration lifting cylinder 87 to descend through the bottom ring 875 until reset, then the reset spring 843 rebounds to drive the blanking piece 842 to retract and reset, when the blanking piece 842 resets, it synchronously drives the turntable 88 to reset.
