Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment technology, and in particular relates to a conveying equipment for urban solid waste transportation and treatment and its usage method. Background Technology

[0002] Conveying equipment is a key component of urban solid waste treatment systems, responsible for transporting various types of solid waste, such as domestic waste, municipal sludge, and construction waste, from collection points to treatment terminals. With the acceleration of urbanization and the deepening of the waste classification system in my country, the volume of solid waste treatment continues to rise, placing higher demands on the continuous operation capacity and operational stability of conveying equipment.

[0003] However, the "mud and water problem" that is common in the transportation of urban solid waste has long plagued the industry. Solid waste often contains a high proportion of organic matter and water. In particular, municipal sludge treated by plate and frame filter press, centrifugal dewatering and other methods is very prone to adhesion on the surface of the conveyor belt. This adhesion is not simply surface wetting, but the result of the interaction between the substance and the conveyor belt material. The adhered sludge will not only block the gaps in the equipment and increase the transmission resistance, but will also gradually wrap around the surface of the roller as the conveyor roller rotates, forming an uneven sludge layer, causing the conveyor belt to run off track and slip, and in severe cases, even causing the equipment to overload and shut down.

[0004] To address these issues, we provide a conveying equipment and its usage method for urban solid waste transportation and treatment. Summary of the Invention

[0009] The present invention is further configured such that the suction mechanism includes baffles respectively disposed in front of and behind the sponge ring, and a squeezing component disposed below the baffles.

[0010] The present invention is further configured such that the anti-drip mechanism includes a connecting pipe connected to the side of the liquid collection shell away from the conveyor belt, and a material guiding component disposed inside the connecting pipe.

[0011] The present invention is further configured such that the adjusting assembly includes a fixed box disposed on one side of the flushing pipe, a motor installed inside the front side of the fixed box, a rotating rod installed at the output end of the motor, a transmission rod disposed below the rotating rod, a first gear installed on the surface of the transmission rod, a threaded rod disposed below the transmission rod, a second gear meshing with the bottom of the first gear, a turntable disposed behind the second gear, an electric telescopic rod installed in front of the turntable, a limiting rod installed at the output end of the electric telescopic rod, a limiting groove opened in front of the second gear, a box body movably connected to the front and rear surfaces of the threaded rod respectively, a threaded sleeve threadedly connected to the front and rear surfaces of the threaded rod respectively, an extrusion wheel installed on the top of the threaded sleeve, a beveled block disposed on the top of the extrusion wheel, springs respectively installed on both sides of the bottom of the beveled block, a connecting rod installed on the top of the beveled block, and a second scraper disposed above the box body.

[0012] The invention is further configured such that a movable plate is installed at the bottom of the threaded sleeve, and the movable plate is slidably connected to the bottom of the housing.

[0013] The present invention is further configured such that the extrusion assembly includes a liquid collection hood disposed below the baffle, an extrusion roller rotatably connected to one side of the liquid collection hood, a liquid guide plate disposed on one side of the extrusion roller, a third scraper installed on the top of the liquid guide plate, and a conduit connected to the bottom of the liquid collection hood.

[0014] The present invention is further configured such that the material guiding assembly includes a first material guiding plate disposed on the side of the connecting pipe near the conveyor belt, second material guiding plates disposed on both sides below the first material guiding plate, and a third material guiding plate installed between the two second material guiding plates.

[0015] The present invention is further configured such that a support plate is provided below the conveyor belt, a groove is provided on the top of the support plate, a guide roller is rotatably connected inside the groove, a material guide shell is provided on one side of the support plate, a horizontal plate is provided below the support plate, and a cover is installed on the top of the frame.

[0016] A method of using a conveying device for transporting and treating urban solid waste includes the following steps:

[0017] S1: The motor drives the second conveyor roller to rotate, which in turn drives the conveyor belt to rotate in conjunction with the first conveyor roller. This allows the solid waste that needs to be processed to be transported. During the transport process, due to the presence of the liquid collection shell, the mud and water flowing out from the front and rear sides of the conveyor belt are collected by the liquid collection shell to prevent it from dripping and affecting the conveyor belt.

[0018] S2: When the second conveyor roller rotates, it will drive the support ring and the sponge ring to rotate synchronously. The mud and water dripping from the conveyor belt at the second conveyor roller will fall onto the surface of the sponge ring and be absorbed by the sponge ring, thereby preventing the mud and water from entering between the second conveyor roller and the conveyor belt and affecting the friction drive between the second conveyor roller and the conveyor belt.

[0019] S3: When the conveyor belt turns to the bottom, the first scraper will scrape off the sludge adhering to its surface, thus avoiding sludge adhesion and reducing the source of mud and water.

[0020] The beneficial effects of this invention are as follows: Through the coordinated operation of the scraping mechanism, the suction mechanism, and the anti-drip mechanism, the problems of conveyor belt slippage, deviation, and sludge accumulation on rollers caused by mud and water adhesion during the transportation of urban solid waste are systematically solved. The first scraper and the adjustable second scraper in the scraping mechanism can achieve layered scraping according to the thickness of the sludge, which not only avoids damage to the conveyor belt caused by excessive load in a single scraping, but also significantly reduces the adhesion and residue of sludge on the surface of the conveyor belt. The suction mechanism uses a sponge ring to absorb the dripping mud and water at the second conveyor roller, and combines it with squeezing... The pressure assembly and the third scraper separate the mud and water from the sand and discharge it into the collection shell, effectively preventing mud and water from entering the friction drive interface between the conveyor roller and the conveyor belt, thus ensuring transmission stability. The anti-drip mechanism guides the mud and water dripping from both sides of the conveyor belt to the connecting pipe in an orderly manner through the liquid collection shell and the material guiding assembly, avoiding mud and water from scattering and causing pollution to the inside of the equipment and the working environment. At the same time, the support plate, guide roller and cross plate and other structures further improve the running stability and scraping effect of the conveyor belt. The cover and negative pressure equipment can also improve the dust removal and deodorization conditions at the work site.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0041] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Example 1

[0043] Please see Figures 1-17This invention relates to a conveying device for transporting and treating urban solid waste, comprising a frame 1, a first conveying roller 2 disposed on one side above the frame 1, a second conveying roller 3 disposed on the other side above the frame 1, a conveyor belt 4 sleeved on the surface of the first conveying roller 2, and a scraping mechanism 5 disposed below the conveyor belt 4; the scraping mechanism 5 includes a first scraper 51 disposed below the conveyor belt 4, which can prevent mud from sticking to the conveyor belt 4; suction mechanisms 6 are disposed at the front and rear of the second conveying roller 3, and the suction mechanism 6 includes a support ring 61 respectively installed on the front and rear surfaces of the second conveying roller 3, and a sponge ring 62 installed on the surface of the support ring 61, which can prevent mud and water from adhering to the second conveying roller 3; and suction mechanisms 6 are disposed at the front and rear of the conveyor belt 4. The anti-drip mechanism 7 includes a liquid collection shell 71 respectively located in front of and behind the conveyor belt 4. The anti-drip mechanism 7 can prevent mud and water from dripping. The scraping mechanism 5 also includes a collection shell 52 located below the first scraper 51, an inclined plate 53 installed at the bottom of the collection shell 52, a flushing pipe 54 installed inside the collection shell 52, a sealing plate 55 bolted to one side of the collection shell 52, and an adjusting component 56 located on one side of the flushing pipe 54. The suction mechanism 6 also includes baffles 63 respectively located in front of and behind the sponge ring 62, and a squeezing component 64 located below the baffles 63. The anti-drip mechanism 7 also includes a connecting pipe 72 connected to the side of the liquid collection shell 71 away from the conveyor belt 4, and a guiding component 73 located inside the connecting pipe 72.

[0044] The frame 1 is equipped with casters on all four sides of its bottom. The first conveyor roller 2 and the second conveyor roller 3 are rotatably connected to the frame 1 through bearings. The first conveyor roller 2 and the second conveyor roller 3 are connected by a conveyor belt 4. The contact length between the first conveyor roller 2 and the conveyor belt 4 is greater than that between the second conveyor roller 3 and the first conveyor roller 2. The conveying equipment consisting of the first conveyor roller 2, the second conveyor roller 3, the frame 1 and the conveyor belt 4 in the figure is only a schematic diagram. During use, its length can be increased according to actual needs.

[0045] The first scraper 51 is in close contact with the conveyor belt 4. The collection shell 52 is fixedly connected to the frame 1. The inlet end of the flushing pipe 54 is threaded to facilitate connection with external water supply equipment and can also be sealed with a sealing cap. A support frame is installed between the flushing pipe 54 and the collection shell 52. Two baffles 63 are located in front of and behind the sponge ring 62, one on the surface of the support ring 61 and the other on the surface of the conveyor roller. They are fixedly connected to both the conveyor roller and the support ring 61. One of them is in close contact with the sponge ring 62. The liquid collection shell 71 is located below the upper belt of the conveyor belt 4 and is fixedly connected to the frame 1. The end of the connecting pipe 72 away from the conveyor belt 4 extends to the end of the frame 1 away from the conveyor belt 4. A flange is installed on the surface of the connecting pipe 72. It can be connected to external mud and water collection equipment through the flange for centralized treatment of mud and water.

[0046] The scraping mechanism 5 is mainly used to remove the sludge adhering to the surface of the conveyor belt 4, preventing the sludge from accumulating and causing the conveyor belt 4 to slip, run off course, or wear excessively. The adjusting component 56 can adjust the height of the second scraper 5618 according to the sludge thickness to achieve layered scraping and avoid excessive load from scraping at one time. The suction mechanism 6 is used to absorb the mud and water dripping near the second conveyor roller 3, preventing the mud and water from entering between the conveyor roller and the conveyor belt 4 and affecting the friction drive. The squeezing component 64 squeezes out the mud and water absorbed by the sponge ring 62 through the squeezing roller 642 and guides it to the liquid collection hood 641, and finally discharges it to the collection shell 52 through the conduit 645. The anti-drip mechanism 7 is used to collect the mud and water dripping from both sides of the conveyor belt 4. The liquid guiding component guides the mud and water to flow smoothly into the connecting pipe 72 to prevent sedimentation in the liquid collection shell 71.

[0047] When working, the motor 562 drives the second conveyor roller 3 to rotate, which in turn drives the first conveyor roller 2 to rotate the conveyor belt 4. The solid waste to be transported can be placed on top of the conveyor belt 4 for transport. During the transport process, mud and water drip from the front and rear sides of the conveyor belt 4 and are collected by the liquid collection shell 71 to prevent the dripping from affecting the conveyor belt 4.

[0048] The mud and water dripping from the second conveyor roller 3 will be absorbed by the sponge ring 62 that rotates synchronously with the second conveyor roller 3, preventing the mud and water from entering between the second conveyor roller 3 and the conveyor belt 4, adhering to the second conveyor roller 3, and affecting the friction drive. When the conveyor belt 4 rotates to the bottom, the second scraper 5618 will scrape off the sludge that is adhering to it. The scraped sludge will be collected by the collection shell 52. The sealing plate 55 will be opened periodically, and the sludge can be cleaned out and centrally processed through the cooperation of external equipment and flushing pipe 54.

[0049] In conventional designs, the width of the first conveyor roller 2 and the second conveyor roller 3 is the same as or wider than the conveyor belt 4. In this case, mud and water will enter between the second conveyor roller 3 and the conveyor belt 4. The current design makes the width of the second conveyor roller 3 smaller than that of the conveyor belt 4 to avoid this situation.

[0050] Example 2

[0051] Please see Figures 11-16Based on Embodiment 1, the adjustment assembly 56 includes a fixed box 561 disposed on one side of the flushing pipe 54, a motor 562 installed inside the front side of the fixed box 561, a rotating rod 563 installed at the output end of the motor 562, a transmission rod 564 disposed below the rotating rod 563, a first gear 565 installed on the surface of the transmission rod 564, a threaded rod 566 disposed below the transmission rod 564, a second gear 567 meshing with the bottom of the first gear 565, a turntable 568 disposed behind the second gear 567, an electric telescopic rod 569 installed in front of the turntable 568, a limiting rod 5610 installed at the output end of the electric telescopic rod 569, and a limit rod 5610 opened in...

[0052] The fixed box 561 is fixedly connected to the frame 1. The front end of the second conveying roller 3 extends into the fixed box 561 and is fixedly connected to the rotating rod 563. The second conveying roller 3 and the fixed box 561 are rotatably connected by bearings. The rear end of the threaded rod 566 extends into the rear box 5612. The transmission rod 564 and the threaded rod 566 are rotatably connected to the fixed box 561 by bearings. The rear end of the threaded rod 566 is rotatably connected to the rear box 5612 by bearings. The thread directions on the front and rear surfaces of the threaded rod 566 are opposite. A heat dissipation vent is provided on the top of the fixed box 561. A dustproof net is installed inside the heat dissipation vent. Synchronous pulleys are installed on the surfaces of the rotating rod 563 and the transmission rod 564. The two synchronous pulleys are connected by a synchronous belt. The synchronous pulleys drive the synchronous belt through tooth meshing. The synchronous pulleys, the synchronous belt, and the meshing drive method between them are all existing mature technologies and will not be described in detail here.

[0053] The second gear 567 is located on the surface of the threaded rod 566 and is hollow. Support rods are installed at the top and bottom of the front of the second gear 567. A limit block is installed in front of the support rod. The limit block is slidably connected to the front side of the interior of the fixed box 561. An annular movable groove adapted to the limit block is opened on the front side of the interior of the fixed box 561. The turntable 568 is installed on the surface of the threaded rod 566. The frame 1 and the collecting shell 52 are fixedly connected to the box body 5612. The extrusion wheel 5614 is in close contact with the oblique cutting block 5615. The bottom of the spring 5616 is fixedly connected to the box body 5612. A moving groove adapted to the movable plate is opened at the bottom of the interior of the box body 5612. The oblique cutting block 5615 is slidably connected to the box body 5612. Slider blocks are installed on both sides of the oblique cutting block 5615. Sliding grooves adapted to the sliders are opened on both sides of the interior of the box body 5612. The top of the connecting rod 5617 extends through to the top of the box body 5612 and is fixedly connected to the second scraper 5618.

[0054] During operation, if the sludge thickness adhering to the surface of conveyor belt 4 is too large, the electric telescopic rod 569 is activated to drive the limiting rod 5610 to insert into the limiting groove 5611. The rotating rod 563 rotates, driving the transmission rod 564 to rotate via the synchronous wheel and synchronous belt. The first gear 565 and the second gear 567 drive the threaded rod 566 to rotate, driving the extrusion wheel 5614 to extrude the oblique cut block 5615 via the threaded sleeve 5613. This causes the second scraper 5618 to move upward, scraping off the first layer of sludge. Then, the first scraper 51 performs the final scraping of the sludge. This layered scraping design avoids the first scraper 51 from being overloaded by scraping it all at once, which could affect the conveyor belt 4. The position of the second scraper 5618 can be adjusted according to the sludge thickness to adjust the thickness of the sludge scraped by the second scraper 5618. The sludge scraped off by the second scraper 5618 also falls into the collection shell 52 for collection.

[0057] The liquid collection hood 641 is fixedly connected to the frame 1 by a fixing rod and is located on the surface of the sponge ring 62. The squeezing roller 642 is rotatably connected to the liquid collection hood 641 by a bearing and squeezes against the sponge ring 62. The liquid guide plate 643 is fixedly connected to the liquid collection hood 641 and is in contact with the squeezing roller 642. The third scraper 644 is in close contact with the sponge ring 62.

[0058] During operation, the sponge ring 62, which absorbs dripping mud and water, rotates with the second conveying roller 3. The third scraper 644 scrapes off the mud and sand adhering to it, and the mud and sand fall into the collection hood 641 via the liquid guide plate 643. Then, the sponge ring 62 rotates and squeezes the squeezed mud and water, which is squeezed out. The mud and water flows into the collection hood 641 via the liquid guide plate 643. When it flows into the collection hood 641, it can wash the mud and sand on the surface of the liquid guide plate 643. Then, it is collected and discharged into the collection shell 52 for centralized treatment via the conduit 645.
