DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 5 As shown, this embodiment provides an environmental protection engineering solid waste treatment equipment, including:

[0033] Base 1, serving as the foundation of the equipment and used for fixing the equipment;

[0034] A pulverizing mechanism is provided on the base 1 and is used for pulverizing solid waste. The outlet at the bottom of the pulverizing mechanism is connected to a discharge pipe 2 provided on the base 1. A screening component for screening the pulverized solid waste is provided on the discharge pipe 2.

[0035] The feeding mechanism includes a feeding hopper 3, in which a one-way component that can be opened and closed is arranged. The solid waste pushes the one-way component open, and after entering the crushing mechanism, the one-way component automatically resets;

[0036] The air return hole 4 is arranged on the one-way component and is opened one-way to the crushing mechanism;

[0037] The dust collecting mechanism comprises a dust collecting pipe 5, one end of which is connected to the feed hopper 3, and the other end of which is connected to the discharge pipe 2, so as to recover the dust generated by the crushing.

[0038] The present invention discloses a solid waste treatment equipment for environmental protection engineering. The base 1 fixes the equipment on the ground, reduces the vibration of the crushing process, and improves the stability of the equipment. The crushing mechanism is arranged on the base 1, and can crush the added solid waste. The solid waste is crushed to form a mixture of powder and particles. The crushed solid waste enters the discharge pipe 2, and is screened by the screening component to separate the solid waste. The solid waste that meets the crushing requirements enters the next process, and the unqualified solid waste is recycled for further treatment. The solid waste to be treated is sent into the feed hopper 3 through the existing transfer equipment, and the solid waste falls into the one-way The weight of the one-way component pushes the one-way component open and then falls into the crushing mechanism for crushing. After the solid waste falls, the one-way component automatically resets after losing external force, and the inlet of the feed hopper 3 is sealed to prevent the smoke and dust generated during crushing from escaping, thereby improving the environmental level and the treatment effect. The return air hole 4 on the one-way component opens unidirectionally to the crushing mechanism, and when the dust collecting mechanism collects the scattered dust, the clean air from the outside can enter the feed hopper 3, avoiding the generation of negative pressure to affect the crushing, and at the same time, the dirty air can be driven out by the clean air, which is convenient for dust recovery and treatment, and reduces the impact of dust. The present invention has a compact structure, can quickly crush and recycle solid waste, greatly reduces the smoke and dust emission during the crushing process, and at the same time effectively recovers the scattered dust, reduces the impact on the environment, improves the efficiency and crushing effect of the crushing process, and is convenient for subsequent recycling.

[0039] Furthermore, a dust collecting fan 30 is provided on the dust collecting pipe 5 to provide power for the flow of the air containing dust and separate the dust at the same time.

[0040] Furthermore, the air outlet of the dust collecting fan 30 enters the discharge pipe 2, which is perpendicular to the side wall of the discharge pipe 2, so that the air outlet is directed toward the screened qualified solid waste to achieve preliminary air separation, and the light materials inside, such as plastics, can be separated according to the different solid waste densities, which is convenient for subsequent processing.

[0041] Further optimization scheme, the one-way component includes a mounting plate 6 arranged in the feed pipe, the bottom end of the mounting plate 6 is hinged with a symmetrically arranged one-way plate 7, and the two one-way plates 7 are hinged to the mounting plate 6 on the side away from each other; the free end of the one-way plate 7 is opened to the crushing mechanism in one direction; a telescopic rod 8 is hinged between the lower end of the free side of the one-way plate 7 and the side wall of the feed hopper 3. The mounting plate 6 is arranged in a ring shape, and its outer wall is fixedly connected to the inner wall of the feed hopper 3. Two symmetrically arranged one-way plates 7 block the inner hole of the mounting plate 6; when the solid waste enters the feed hopper 3 and falls on the one-way plate 7, the one-way plate 7 is forced to compress the telescopic rod 8, so that the telescopic rod 8 shrinks, and the one-way plate 7 deflects the crushing mechanism with the two ends away from each other as the axis, so that the solid waste slides into the crushing mechanism for crushing; and after the solid waste slides, the one-way plate 7 loses the external force, and the telescopic rod 8 automatically rebounds, so that the two one-way plates 7 are automatically reset, and the center hole of the mounting plate 6 is sealed to prevent the smoke generated by the crushing from escaping.

[0042] Furthermore, a flexible sealing ring is embedded in the bottom end of the mounting plate 6 of the present embodiment. When the one-way plate 7 is reset, the top end of the one-way plate 7 contacts the sealing ring, thereby improving the sealing performance. At the same time, it can ensure that no hard collision occurs when the one-way plate 7 rebounds, thereby improving safety, reducing noise generation, and avoiding deformation of the one-way plate 7 caused by bumps, thereby extending the service life of the equipment and reducing maintenance pressure.

[0043] Furthermore, in this embodiment, the side wall of the feed hopper 3 and the free end of the one-way plate 7 are provided with an articulated seat 9, and both ends of the telescopic rod 8 are provided with an articulated head 10 corresponding to the articulated seat 9, and the articulated head 10 is hinged to the articulated seat 9 through a rotating shaft.

[0044] Further optimization scheme, the return air holes 4 are arranged in an array with equal spacing on the one-way plate 7; the bottom end of the return air hole 4 is fixedly connected with a return air cap 11, and a lifting plate 12 is slidably arranged inside the return air cap 11, and the lifting plate 12 elastically slides between the upper and lower sides of the air inlet 13 on the side wall of the return air cap 11. The return air hole 4 is arranged on the one-way plate 7, and the bottom end thereof is covered with a return air cap 11, and the lifting plate 12 slides and rises inside the return air cap 11. When the smoke and dust generated are collected by exhausting air, negative pressure is generated in the feed hopper 3, and the negative pressure acts on the lifting plate 12 through the air inlet 13, so that the lifting plate 12 descends until the lifting plate 12 falls under the air inlet 13, so that the air inlet 13 is connected with the outside, and the fresh air from the outside enters the feed hopper 3 to replace the dirty air containing smoke and dust, so as to facilitate the collection of smoke and dust.

[0045] When the air inlet 13 is lowered from the bottom of the air hopper 13, the air inlet 13 is disconnected from the outside, and the dust in the air hopper 13 is prevented from flying.

[0046] In a further optimized solution, the screening assembly includes a screening net 16 obliquely arranged in the discharge pipe 2, the screening net 16 is located below the crushing mechanism, and a vibration motor 17 is arranged on the screening net 16 to screen the crushed solid waste through vibration. After the solid waste is crushed, it forms particles and falls on the screening net 16. At the same time, the vibration motor 17 drives the screening net 16 to vibrate, so that the particles falling on the screening net 16 shake, which accelerates the screening of the particles. The crushed particles are discharged through the discharge pipe 2 after passing through the screening net 16, and the unqualified particles are recycled and crushed again.

[0047] Further optimization scheme, the lower end of the screening net 16 is connected with a discharge pipe 18, the discharge pipe 18 is connected with a collection box 19, and the collection box 19 is connected with the feed hopper 3 above the crushing mechanism through a lifter 20. Unqualified particles are vibrated to the bottom end of the screening net 16, and discharged from the side wall of the discharge pipe 2 into the discharge pipe 18 and collected in the collection box 19. The collected unqualified particles are returned to the feed hopper 3 through the lifter 20 for re-crushing.

[0048] Furthermore, the lifter 20 of this embodiment includes a lifting pipe 31 arranged in the aggregate box 19, and the top end of the lifting pipe 31 is connected to the feed hopper 3 through the transfer pipe 34, so that unqualified solid waste enters the feed hopper 3; the bottom end of the lifting pipe 31 passes through the bottom end of the aggregate box 19 and is installed with a lifting motor 32, and the output shaft of the lifting motor 32 extends into the lifting pipe 31 and is connected to the screw conveyor 33 for transmission; the unqualified particles are carried out to the bottom end of the lifting pipe 31, and are lifted by the rotation of the screw conveyor 33, and are transferred into the feed hopper 3 through the transfer pipe 34 to be crushed again.

[0049] Furthermore, the lifting pipe 31 of this embodiment is divided into two corresponding parts, which are respectively fixed and connected to the upper and lower sides of the aggregate box 19, wherein the lifting motor 32 is installed at the bottom end of the lower lifting pipe 31, and the screw conveyor 33 extends from the bottom to the upper end of the lifting pipe 31, and is used to lift the particulate material collected in the aggregate box 19 upward.

[0050] Further optimizing the scheme, the crushing mechanism includes a crushing box 21 installed on the base 1 and connected to the outlet of the feed hopper 3. Two relatively rotating crushing rollers 22 are arranged in the crushing box 21. The two crushing rollers 22 are arranged in a transmission and rotate relatively toward the middle. Any crushing roller 22 is connected to a crushing motor 23 arranged on the base 1. The two crushing rollers 22 rotate relatively in the crushing box 21. The crushing motor 23 serves as a driving source and drives any crushing roller 22 to rotate through a coupling 27. The two realize relative rotation through the meshing of the driving gear 28 and the driven gear 29, so that the solid waste is gathered in the middle and crushed to form small particles.

[0051] In a further optimized solution, two guide blocks 24 are arranged opposite to each other in the crushing box 21, and the two guide blocks 24 are arranged obliquely toward the area between the two crushing rollers 22. The cross section of the guide block 24 is triangular, so that the solid waste falling into the feed hopper 3 is guided between the two crushing rollers 22, which is convenient for crushing.

[0052] In a further optimized solution, a plurality of crushing teeth 25 are arranged on the outer wall of the crushing roller 22, and the crushing teeth 25 correspondingly arranged on the two crushing rollers 22 are staggered to hook the solid waste between the two crushing rollers 22. The crushing teeth 25 are arranged in a hook shape and face the position between the two crushing rollers 22, so that they can hook the solid waste, facilitate crushing, prevent the solid waste from sliding, and improve the crushing efficiency; at the same time, the staggered crushing teeth 25 can increase the crushing efficiency of the two crushing rollers 22 and improve the crushing effect.

[0053] Furthermore, a plurality of mounting holes are provided on the two crushing rollers 22, and the crushing teeth 25 are mounted on the crushing rollers by bolts, so that the position can be easily adjusted and the crushing teeth 25 can be easily disassembled for maintenance and replacement. Firstly, the difficulty of the process caused by the integral production of the crushing rollers 22 is reduced, and at the same time, the overall replacement can be avoided after damage, and the damaged crushing teeth 25 can be removed and replaced.

[0054] Further optimization scheme, the base 1 is provided with a control box 26, and the control box 26 is provided with a control module for controlling the automatic operation of the device. The control module in the control box 26 has programmable capability, can control the operation of the device, and realize automatic control; at the same time, the control module can also monitor the operation status of the device. When the abnormal operation of the device is detected, the control module will issue an alarm and control the device to stop working to prevent a larger fault.
