[0002] The Z-type bucket elevator is a common material conveying device, primarily used for vertical and inclined conveying of various granular and bulk materials. Its name comes from the different locations of its inlet and outlet, which resemble the letter Z. Z-type bucket elevators are also known as rotating bucket elevators, induced bucket elevators, Z-type elevators, Z-loaders, chain bucket elevators, or bucket elevators. Z-type bucket elevators use chains or belts to drive the bucket along a Z-shaped trajectory within a sealed housing, achieving vertical lifting and horizontal conveying of materials. They are widely used in various industrial fields.

[0024] The plurality of fixed air holes 1812 and the plurality of adjusting air holes 1815 are consistent in size and one-to-one correspondence, and in the initial state, the adjusting air holes 1815 and the fixed air holes 1812 are staggered.

[0025] The bottom of the air chamber is provided with a fixing rod 1819, the end of the fixing rod 1819 is provided with a fixing sleeve 1820, the fixing sleeve 1820 is rotatably provided with a pole 1821, the end of the pole 1821 close to the interception net 1802 is provided with a conductive column 1822, the side wall of the conductive column 1822 is circumferentially provided with a plurality of metal blades 1823, the end of the conductive column 1822 is provided with a rotation sensor 1824, the center of the adjusting baffle 1814 is provided with an angle sensor, the rotation sensor 1824, the angle sensor and the driving motor 1817 are electrically connected, when the interception net 1802 in different air chamber areas is attached with different degrees of dust, the airflow pushes the metal blades 1823 to rotate through the interception net 1802, so that the metal blades 1823 drive the conductive column 1822 to rotate synchronously, the rotation rate of the conductive column 1822 is detected through the rotation sensor 1824, when the rotation rate of the conductive column 1822 is reduced, the rotation sensor 1824 can control the driving motor 1817 to operate, so that the driving gear 1818 drives the adjusting baffle 1814 to rotate, the overlapping area of the adjusting air hole 1815 and the fixed air hole 1812 is gradually increased, and when the rotation angle of the adjusting baffle 1814 detected through the angle sensor meets the requirement, the driving motor 1817 is controlled to stop operating, so that the overlapping degree of the adjusting air hole 1815 and the fixed air hole 1812 can be positively and negatively feedback controlled according to the amount of dust on the interception net 1802, and different air chambers can be independently regulated and controlled according to the amount of dust on the interception net 1802 in the corresponding area.

[0026] The rotation sensor 1824 controls the driving motor 1817 to drive the adjusting baffle 1814 to rotate at a corresponding angle under the control of the angle sensor according to the rotation speed of the conductive column 1822, so as to adjust the overlapping area of the adjusting air hole 1815 and the fixed air hole 1812.

[0027] Two magnetic plates 1901 are symmetrically installed in the air chamber. The two magnetic plates 1901 are respectively positive and negative poles. A rotary joint is installed at the end of the pole 1821 away from the conductive column 1822. A current sensor 1902 is installed on the top of the air chamber. The current sensor 1902 is connected to the rotary joint through a wire 1903. A plurality of guide rails 1904 are installed on the upper part of the port of the opening 1801 away from the cover 1803. The plurality of guide rails 1904 correspond to the air chambers one by one. Slide seats 1905 are slidably installed on the plurality of guide rails 1904. A cleaning brush 1906 is installed on the slide seat 1905. The cleaning brush 1906 is in contact with the intercepting net 1802. The guide rail 1904 is electrically connected to the current sensor 1902. When the metal blade 1823 rotates, the metal The blade 1823 can cut the magnetic flux lines between the two magnetic plates 1901, so that the generated current can enter the current sensor 1902 through the wire 1903 and be monitored. The guide rail 1904 is controlled to drive the slide 1905 to move back and forth at a speed according to the strength of the current monitored by the current sensor 1902. When there is too much dust on the interception net 1802, the rotation speed of the metal blade 1823 is reduced, and the current intensity generated by the current sensor 1902 is reduced, so that the guide rail 1904 can drive the slide 1905 to move back and forth at a faster speed, which is beneficial for the slide 1905 to drive the cleaning brush 1906 to synchronously clean the interception net 1802 at the air chamber, and it is convenient to control the cleaning frequency of the cleaning brush 1906 according to the amount of dust on the interception net 1802.

[0028] Working principle of the present invention: When lifting materials, start the servo motor 7 so that the conveyor chain 8 can drive the hopper 9 to lift and convey under the transmission of the driving gear 4, the transmission gear 6 and the driven gear 5. At the same time, the connecting hole 14 on the hopper 9 is connected to the connecting pipe 13 through the hopper shaft 15, and then the embedded shaft 11 is engaged with the card slot 10 at the upper end of the next hopper 9, so that the adjacent hoppers 9 are softly connected through the connecting pipe 13, the soft plate 12 and the embedded shaft 11 to form a continuous hopper, so that each hopper 9 is connected to each other, thereby preventing the hopper 9 from tilting and material spilling during lifting and turnover, thereby achieving the effect of preventing material leakage.

[0029] When the lower hopper 3 is discharging, the air pump 1807 is started, and the suction pipe 1808 can absorb the dust in the lower hopper 3 through the connecting pipe 1806 and the air outlet 1805, and the inhaled air flow can be filtered through the interception net 1802. At the same time, the air pump 1807 can transport the inhaled air flow to the annular exhaust pipe 1809 through the air supply pipe 1810, so that the annular exhaust pipe 1809 can spray air flow downward to form an air flow dust-proof layer.

[0030] When the interception net 1802 at the air chamber is attached with dust, the driving motor 1817 can be started according to the air permeability of the interception net 1802 at the air chamber, and through the meshing of the driving teeth 1818 and the ring teeth 1816, the ring teeth 1816 can drive the adjusting baffle 1814 to rotate, so that the adjusting baffle 1814 drives the adjusting air holes 1815 to rotate synchronously, thereby controlling the overlapping area of the adjusting air holes 1815 and the fixed air holes 1812, improving the air intake and air pressure of the air chamber, and thereby ensuring the stable flow of the airflow.

[0031] When the interception net 1802 in different air chamber areas is attached with different amounts of dust, the airflow pushes the metal blade 1823 to rotate through the interception net 1802, so that the metal blade 1823 drives the conductive column 1822 to rotate synchronously, and the rotation rate of the conductive column 1822 is detected by the rotation sensor 1824. When the rotation rate of the conductive column 1822 decreases, the rotation sensor 1824 can control the driving motor 1817 to operate, so that the driving teeth 1818 drive the adjusting baffle 1814 to rotate, and the overlapping area of the adjusting air holes 1815 and the fixed air holes 1812 is gradually increased. When the rotation angle of the adjusting baffle 1814 detected by the angle sensor meets the requirements, the driving motor 1817 is controlled to stop operating, so that the overlapping degree of the adjusting air holes 1815 and the fixed air holes 1812 can be positively feedback controlled according to the amount of dust on the interception net 1802, and different air chambers can be independently regulated and controlled according to the amount of dust on the interception net 1802 in the corresponding area.

[0032] When the metal blade 1823 rotates, the metal blade 1823 can cut the magnetic induction lines between the two magnetic plates 1901, so that the current formed can enter the current sensor 1902 through the wire 1903 and be monitored. The reciprocating movement rate of the sliding seat 1905 driven by the guide rail 1904 is controlled according to the strength of the current monitored by the current sensor 1902. When the amount of dust on the interception net 1802 is too much, the rotation speed of the metal blade 1823 decreases, and the current sensor 1902 monitors the decrease of the current intensity, so that the reciprocating movement rate of the sliding seat 1905 driven by the guide rail 1904 can be increased, which is conducive to the synchronous cleaning of the interception net 1802 at the air chamber by the cleaning brush 1906 driven by the sliding seat 1905.

[0033] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the patent document.
