Description

Technical Field

[0001] The utility model belongs to the field of garbage treatment, and particularly relates to a pneumatic garbage collection system. Background Art

[0002] A pneumatic conveying system is a material collection system with a fan as the power source. During the operation of the system, the material is driven by a high-speed air flow and moves suspended or semi-suspended in the conveying pipeline along the wind to the target position, and then the material and the air flow are separated by a gas-solid separation device for collection. A garbage pneumatic conveying system is a pneumatic conveying system with garbage as the material, and the in-building garbage pneumatic conveying system is a system that sets the garbage discharge port inside high-rise buildings and then unifies the garbage to enter the collection station through the pipelines and underground pipe networks arranged in the building for recycling.

[0003] In the in-building system, the garbage put by users directly enters the vertical chute and is temporarily stored in the garbage storage section; when the garbage is centrally collected, the discharge valve below the storage section is opened for collection; because the collected garbage has a storage period and cannot be discharged in real time, when the garbage in the storage section transitions and the discharge valve is opened, the garbage in the storage section cannot be well sucked into the treatment device for treatment, and it is easy to cause blockage; moreover, when the garbage put into the vertical chute enters the storage section, it will cause a certain impact on the side wall of the storage section, and it is easy to damage the side wall of the storage section in the long run, thereby affecting the use of the storage section. Summary of the Utility Model

Detailed Description of the Preferred Embodiments

[0025] The present utility model will be further described below through specific embodiments.

[0026] Referring to Figures 1 to 6 shown, a pneumatic garbage collection system includes a vertically arranged receiving section 1 for garbage to enter, a storage section 2 connected to the receiving section 1 for temporarily storing garbage, a discharge valve 3 connected to the lower end of the storage section 2, an auxiliary air intake section 4 connected between the lower end of the receiving section 1 and the upper end of the storage section 2, a conveying pipeline 5 connected to the discharge valve 4 for conveying garbage to corresponding treatment equipment, and an intake valve provided at the front end of the conveying pipeline 5 for adjusting the intake air volume.

[0027] Storage section 2, including a first vertical connection section 21 connected to the lower end of the receiving section 1, a second vertical connection section 22 connected to the input end of the discharge valve 3, a storage section 23 inclined between the first vertical connection section 21 and the second vertical connection section 22, and a wear-resistant lining 24 provided on the inner wall of the storage section 23 opposite to the first vertical connection section 21. Among them, the first vertical connection section 21 and the second vertical connection section 22 are arranged staggered up and down.

[0028] The wear-resistant lining 24 includes a rubber buffer pad 241 attached to the inner wall of the storage section 23 and a wear-resistant plate 242 provided on the top surface of the rubber buffer pad 241; specifically, a positioning groove 25 for embedding the rubber buffer pad 241 is formed on the inner wall of the storage section 23, and the depth of the positioning groove 25 is less than the height of the rubber buffer pad 241. By providing the rubber buffer pad 241 to buffer the impact received by the wear-resistant plate 242, the hard contact between the wear-resistant plate 242 and the inner wall of the storage section 23 is reduced, further reducing the impact and damage to the inner wall of the storage section 2 when the garbage enters, and improving the service life of the storage section 2; further, the wear-resistant lining 24 is fixed to the inner wall of the storage section 2 by bolts, and the setting of the positioning groove 25 can cooperate with the bolts to achieve the rapid installation of the wear-resistant lining 24.

[0029] Auxiliary air intake section 4, including an air intake section 41, an adjustment section 42, and a flexible clamp 43 arranged in sequence from top to bottom. Among them, the air intake section 41 is connected to the lower end of the receiving section 1, and the flexible clamp 43 is connected between the lower end of the adjustment section 42 and the upper end of the first vertical connection section 21.

[0030] The air intake section 41 includes an air intake pipe body 411, a connection ring 412 provided at the upper end of the air intake pipe body 411 and connected to the lower end of the receiving section 1, and a plurality of air intake holes 413 circumferentially distributed on the outer peripheral surface of the air intake pipe body 411; specifically, the connection ring 412 and the lower end of the receiving section 1 or the upper end of the air intake pipe body 411 are both full-welded connections to ensure the stability of the connection between the air intake section 41 and the receiving section 1; through the circumferentially distributed plurality of air intake holes 413, the air intake volume of the auxiliary air intake section 4 is increased to ensure that the garbage in the storage section 2 can smoothly enter the conveying pipeline 5.

[0031] The adjustment section 42 includes an adjustment pipe body 421 and an adjustment component provided on the adjustment pipe body 421 for adjusting the intake air volume of the storage section. Specifically, the adjustment component includes an adjustment plate 422 that can move inward from the outside of the adjustment pipe body 421 into the adjustment pipe body 421, and a moving member 423 provided on the outer peripheral surface of the adjustment pipe body 421 for driving the adjustment plate 422 to move. Further, an arc-shaped moving hole 4211 extending inward is formed on the outer peripheral surface of the adjustment pipe body 421 for the adjustment plate 422 to move back and forth, and the arc-shaped moving hole 4211 is semicircularly arranged, so that the maximum inward process of the adjustment plate 422 can horizontally cover half of the inner cross-section of the adjustment pipe body 421; when the storage section 2 is in the storage cycle, the adjustment plate 422 moves outward to the outside of the adjustment pipe body 421, so that the inside of the adjustment pipe body 421 is completely opened without affecting the normal feeding of garbage.

[0032] The moving member 423 includes two mounting plates 424 oppositely arranged on the outer peripheral surface of the adjustment pipe body 421, a moving motor 425 and a balance block 426 respectively arranged on the two mounting plates 424, a screw-nut pair 427 connected between the output shaft of the moving motor 424 and the bottom of the adjustment plate 422, and a guiding member 428 arranged between the balance block 426 and the bottom of the adjustment plate 422; specifically, the guiding member 428 includes a guiding rod 4281 arranged on the balance block 426 and extending along the moving direction of the adjustment plate 422, a guiding sleeve 4282 arranged at the bottom of the adjustment plate 422 and cooperating with the guiding rod 4281, and a limiting block 4283 arranged at the front end of the guiding rod 4281 to prevent the guiding sleeve 4282 from disengaging from the guiding rod 4281. By arranging the guiding member 428 to cooperate with the screw-nut pair 427, it is ensured that the adjustment plate 422 moves back and forth stably; further, the guiding sleeve 4282 includes a guiding sleeve body 4284 sleeved on the guiding rod 4281 and a connecting block 4285 arranged on the outer periphery of the guiding sleeve body 4284 and connected to the bottom of the adjustment plate 422.

[0033] During operation, the adjusting plate 422 is located outside the adjusting pipe body 421 to fully open the inside of the adjusting pipe body 421. Garbage enters the receiving section 1 through the feeding opening and falls into the storage section 2 by gravity for temporary storage. When the garbage storage reaches the conveying condition, the negative pressure fan in the processing equipment is started to form an air flow in the conveying pipeline 5. At this time, the discharge valve 3 is opened to discharge the garbage in the storage section 2. After the discharge valve 3 is opened, the intake valve at the front end of the conveying pipeline 5 is controlled to reduce the intake air volume by half to reduce the air entering the conveying pipeline 5 from the intake valve, so that part of the air enters the adjusting section 42 through the intake section 41, and the powerful air flow in the adjusting section 42 is used as an auxiliary to bring all the garbage in the storage section 2 into the conveying pipeline 5. When the garbage discharge is completed, the intake valve is fully opened again, and the adjusting plate 422 is controlled to move inward to horizontally cover half of the inner cross-section of the adjusting pipe body 421, and the intake air volume of the adjusting section 42 is controlled so that most of the air enters the conveying pipeline 5 from the intake valve to meet the air flow requirement of the garbage in the conveying pipeline 5. When the garbage conveying is completed, the adjusting plate 422 is controlled to move outward to reset to fully open the inside of the adjusting pipe body 421, and the intake valve and the discharge valve 3 are controlled to be fully closed to complete the conveyance of the garbage this time; the storage of the next cycle of garbage is carried out.

[0034] Through the structural composition of the storage section 2 in this application, wear-resistant liners 24 are provided on the inner wall of the storage section 2 opposite to the first vertical connection section 21, so that the garbage entering from the receiving section 1 does not directly contact the inner wall of the storage section 23 when entering the storage section 23. The impact it receives is buffered by the wear-resistant liners 24, thereby reducing the impact and damage to its inner wall, reducing the maintenance cost of the storage section 2, and effectively improving the service life of the storage section 2. In addition, the auxiliary intake section 4 is provided in cooperation with the intake valve at the front end of the conveying pipeline 5, so that the garbage in the storage section 2 can be smoothly discharged into the conveying pipeline 5 and conveyed to the corresponding processing equipment, effectively solving the problem of pipe blockage in the storage section 2 and improving the stability of the system operation.

[0035] The above are only the preferred embodiments of the present invention, and thus cannot limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the present invention application and the content of the specification should still fall within the scope covered by the present invention application.
