Description

Technical Field

[0001] This utility model relates to the field of waste treatment, specifically to an anti-slip and anti-displacement automatic lifting and conveying device for hazardous waste materials. Background Technology

[0002] Waste treatment plants are comprehensive facilities specifically designed, constructed, and operated for the centralized treatment, disposal, or resource utilization of municipal solid waste, industrial waste, or other types of waste. To improve the treatment efficiency of hazardous waste, it is often processed by crushing it into smaller pieces.

[0003] Waste treatment plants often have hazardous waste lifting and conveying systems to raise hazardous waste materials before feeding them into crushers. Existing hazardous waste lifting and conveying systems are mostly roller-type, meaning multiple rollers arranged in sequence transport hazardous waste. However, when transporting hazardous waste such as oil drums, slippage between the drums and the rollers prevents them from moving forward. Therefore, pallets are needed as carriers to transport the oil drums, and these pallets are also crushed and incinerated along with the oil drums. The pallets transported with the oil drums increase the cost of hazardous waste crushing, and the incinerated pallets further increase disposal costs and carbon emissions. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-slip and anti-displacement automatic lifting and conveying device for hazardous waste materials that can stably transport hazardous waste materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes supports located on the left and right sides. The supports on the left and right sides are respectively provided with an upper side baffle and a lower transmission groove. A transmission channel for transporting hazardous waste is formed between the side baffles on the left and right sides. A drive shaft located at the rear and a driven shaft located at the front are rotatably arranged between the transmission grooves on the left and right sides. The driven shaft is higher than the drive shaft. A reduction motor driving the drive shaft to rotate forward is provided on one side of the support. Transmission sprockets are fixedly installed in each transmission groove on the drive shaft and driven shaft respectively. A main transmission sprocket is sleeved between the transmission sprockets on the same side. A transmission chain with a driven shaft and a driven shaft is provided. Multiple planar chain plates are arranged sequentially between the transmission chains on the left and right sides along the circulation direction. A limiting chain plate is provided every few planar chain plates between the transmission chains on the left and right sides. A limiting groove is provided behind the limiting chain plate relative to the circulation direction of the transmission chain. A limiting baffle is hinged in the limiting groove and swings up and down and extends into the transmission channel. The width of the limiting baffle is the same as the width of the transmission channel. A V-shaped limiting space is formed between the limiting baffle and the limiting chain plate where the limiting baffle is located. A return torsion spring is provided between the limiting groove and the limiting baffle to reduce the V-shaped opening of the limiting space.

[0006] By adopting the above technical solution, when it is necessary to lift hazardous waste, the hazardous waste is placed on the rear end of the automatic lifting conveyor, that is, the lower flat chain plate. The hazardous waste will rise with the transmission chain and eventually fall into the crusher after reaching the front end of the automatic lifting conveyor. Even if the oil drum rolls relative to the flat chain plate due to its cylindrical structure, it will be limited by the limiting space formed by the limiting baffle and the limiting chain plate and rise together with the limiting space. The above structure has the following advantages: ① The limiting space restricts the oil drum, effectively preventing slippage and displacement, eliminating the need for a pallet to reduce its rolling motion, and thus avoiding a series of problems caused by using a pallet; ② As the size of the oil drum increases, its mass also increases accordingly. Since the limiting baffle is hinged to the limiting groove, the increased mass of the oil drum will squeeze the limiting baffle, increasing the V-shaped opening of the limiting space. As the V-shaped opening increases, the supporting area of ​​the limiting space for the oil drum also increases, thereby improving the limiting reliability of the limiting space. Combined with the return torsion spring, the V-shaped opening of the limiting space can adaptively adjust and stabilize according to the weight of the oil drum. ③ When hazardous waste is placed into the rear end of the automatic lifting conveyor, it inevitably impacts the transmission chain, causing vibration. This vibration affects the overall transmission stability. The limiting baffle absorbs this vibration by contacting the hazardous waste and uses its own high-frequency vibration to eliminate the impact of the vibration, further improving the transmission stability. ④ A transmission channel is formed between the side baffles on the left and right sides. By hiding the transmission chain in the transmission groove of the frame on the left and right sides, the limiting baffle, whose width is the same as the width of the transmission channel, can fully limit all hazardous waste put into the transmission channel, further reducing the possibility of side leakage.

[0007] The present invention is further configured such that: a limiting slope is provided in front of the limiting groove relative to the circulation direction of the transmission chain; when the limiting baffle abuts against the limiting slope, the V-shaped opening angle of the limiting space is at its minimum value, which is above 90° and below 110°.

[0008] By adopting the above technical solution, the V-shaped opening angle of the limiting space is limited to a minimum of 105° by the limiting slope, so that the limiting space maintains a suitable opening when no external force is applied, stably receiving all the hazardous waste materials put in, and avoiding side leakage of hazardous waste materials caused by the opening being too small.

[0009] The present invention is further configured such that when the limiting baffle abuts against the limiting slope, the limiting baffle located in the transmission channel completely covers the limiting groove of the same limiting chain plate in the vertical direction.

[0010] By adopting the above technical solution, even when the V-shaped opening angle of the limiting space is at its minimum, the limiting baffle can completely cover the limiting groove, preventing hazardous waste materials placed in the transmission channel from directly passing through the limiting groove into the transmission structure, thereby ensuring the reliable operation of the equipment.

[0011] The present invention is further configured such that: a compression plate parallel to the transmission chain is provided between the brackets on the left and right sides below the transmission chain; when the compression plate abuts against the limiting baffle, it expands the V-shaped opening of the limiting space and maintains the expanded state; when the V-shaped opening of the limiting space is in the expanded state, the included angle of the V-shaped opening is above 150° and below 170°.

[0012] By adopting the above technical solution, the limiting baffle circulating to the top of the transmission chain (within the transmission channel) is in the transmission state, while the limiting baffle circulating to the bottom of the transmission chain is in the non-transmission state. In order to reduce the equipment space occupied by the limiting baffle in the non-transmission state, a compression plate is added below the transmission chain. The compression plate squeezes the limiting baffle, which expands the V-shaped opening of the limiting space and keeps it in an expanded state, thereby reducing the height space occupied by the limiting space. This allows the feeding position at the rear end of the automatic lifting conveyor to be designed lower, making it easier to connect with other equipment / devices.

[0013] The present invention is further configured such that: a guide platform is horizontally provided at the front end of the compression plate, and a guide roller is rotatably provided at the other end of the limiting baffle that is hinged to the limiting groove. When the guide roller rolls along the guide platform, the V-shaped opening of the limiting space gradually expands until the guide roller rolls to the compression plate and remains in an expanded state, and continues to roll along the compression plate.

[0014] By adopting the above technical solution, the guide roller at the end of the limiting baffle, in conjunction with the guide platform at the front end of the compression plate, guides the V-shaped opening of the limiting space to gradually expand in a rolling manner until it expands to the extent that it matches the compression plate. This makes the transition of the limiting baffle from the transmission state to the non-transmission state smoother, while reducing the friction generated when the limiting baffle moves continuously along the compression plate, making the circulation of the transmission chain smoother. In addition, when hazardous waste accumulates above the limiting baffle, the guide roller also has a certain limiting function.

[0015] The present invention is further configured such that: the front end of the guide platform is provided with a guide ramp whose height gradually decreases from back to front.

[0016] By adopting the above technical solution and adding a guide ramp, the trajectory of the vertically falling hazardous waste is changed, causing it to gradually shift forward and approach the center of the crusher's feed inlet, thus stably falling into the feed inlet and further reducing the possibility of side leakage.

[0017] The present invention is further configured such that: a delay platform is horizontally arranged at the rear end of the compression plate, and the rear end and lower end of the delay platform are aligned with the rear end and lower end of the bracket.

[0018] By adopting the above technical solution and adding a delay platform, the limit baffle can be effectively delayed from resetting from the non-transmission state to the transmission state, making the transition of the limit baffle from the lowest point of the transmission chain smoother.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figure 1 — Figure 6As shown, this utility model discloses an anti-slip and anti-displacement automatic lifting and conveying device for hazardous waste materials, including supports 1 on the left and right sides. The supports 1 on the left and right sides are respectively provided with an upper side baffle 11 and a lower transmission groove 12. A transmission channel 17 for conveying hazardous waste materials is formed between the side baffles 11 on the left and right sides. A drive shaft 13 located at the rear and a driven shaft 14 located at the front are rotatably arranged between the transmission grooves 12 on the left and right sides. The driven shaft 14 is higher than the drive shaft 13. One of the supports 1 is provided with a drive shaft 1. A forward-rotating geared motor 15 has a drive shaft 13 and a driven shaft 14, each fixedly mounted with a drive sprocket 131 within a transmission groove 12. A transmission chain 132, forming the transmission connection between the drive shaft 13 and the driven shaft 14, is sleeved between the drive sprockets 131 on the same side. Multiple planar chain plates 2 are sequentially arranged between the drive chains 132 on both the left and right sides along the circulation direction. Limiting chain plates 3 are installed every few planar chain plates 2 between the drive chains 132 on both the left and right sides. Generally, there are three limiting chain plates 3, but the number can be adjusted based on the total number of planar chain plates 2. The number of planar chain plates 2 between the limiting chain plates 3 is finely adjusted by adding or removing one, so that the planar chain plates 2 fill the transmission chain 132. A limiting groove 31 is provided behind the limiting chain plate 3 relative to the transmission chain 132 in the cyclic direction. A limiting baffle 32, which swings up and down and extends into the transmission channel 17, is hinged within the limiting groove 31. The width of the limiting baffle 32 is the same as the width of the transmission channel 17. A V-shaped limiting space 33 is formed between the limiting baffle 32 and the limiting chain plate 3 containing the limiting baffle 32. A [missing information - likely a design feature] is provided between the limiting groove 31 and the limiting baffle 32. A reset torsion spring 34 is provided to reduce the V-shaped opening of the limiting space 33. When it is necessary to lift the hazardous waste, the hazardous waste is placed on the rear end of the automatic lifting conveyor, that is, the lower flat chain plate 2. The hazardous waste will rise with the transmission chain 132 and eventually fall into the crusher after reaching the front end of the automatic lifting conveyor. Even if the oil drum rolls relative to the flat chain plate 2 due to its cylindrical structure, it will be limited by the limiting space 33 formed by the limiting baffle 32 and the limiting chain plate 3 and rise together with the limiting space 33.The above structure has the following advantages: ① The limiting space 33 limits the oil drum, effectively preventing slippage and displacement, eliminating the need for a pallet to reduce its rolling motion, and thus avoiding a series of problems caused by using a pallet; ② As the size of the oil drum increases, its mass also increases accordingly. Since the limiting baffle 32 is hinged to the limiting groove 31, the increased mass of the oil drum will squeeze the limiting baffle 32, increasing the V-shaped opening of the limiting space 33. As the V-shaped opening increases, the supporting area of ​​the limiting space 33 for the oil drum also increases, thereby improving the limiting reliability of the limiting space 33. Combined with the return torsion spring 34, the V-shaped opening of the limiting space 33 can adaptively adjust according to the weight of the oil drum. And it remains stable at the adjusted angle; ③ When hazardous waste is put into the rear end of the automatic lifting conveyor, it inevitably impacts the transmission chain 132, which in turn causes vibration. This vibration will affect the overall transmission stability. The limiting baffle 32 absorbs this vibration by contacting the hazardous waste and uses its own high-frequency vibration to eliminate the impact of the vibration, further improving the transmission stability; ④ A transmission channel is formed between the side baffles 11 on the left and right sides. By hiding the transmission chain 132 in the transmission groove 12 of the frame on the left and right sides, the limiting baffle 32, whose width is the same as the width of the transmission channel, can fully limit all hazardous waste put into the transmission channel, further reducing the possibility of side leakage.

[0028] The limiting groove 31 is provided with a limiting slope 311 in front of the transmission chain 132 in the cyclic direction, and the limiting baffle 32 abuts against the limiting slope 311 (e.g., Figure 4 As shown, the V-shaped opening angle α of the limiting space 33 is at its minimum value, which is above 90° and below 110°. The limiting slope 311 restricts the V-shaped opening angle α of the limiting space 33 to a minimum value of above 90° and below 110°, so that the limiting space 33 maintains a suitable opening when no external force is applied, stably receiving all the hazardous waste materials put in, and avoiding side leakage of hazardous waste materials caused by the opening being too small. In this embodiment, the minimum value of the V-shaped opening angle α of the limiting space 33 is preferably 105°.

[0029] The limiting baffle 32 abuts against the limiting slope 311 (e.g.) Figure 4 As shown, the limiting baffle 32 located in the transmission channel 17 completely covers the limiting groove 31 located on the same limiting chain plate 3 in the vertical direction. The dotted line represents the area covered by the limiting baffle 32. When the V-shaped opening angle of the limiting space 33 is the smallest, the limiting baffle 32 can also completely cover the limiting groove 31, preventing hazardous waste materials put into the transmission channel 17 from directly passing through the limiting groove 31 and entering the transmission structure, thereby ensuring the reliable operation of the equipment.

[0030] A compression plate 16, parallel to the transmission chain 132, is provided between the left and right supports 1, below the transmission chain 132. When the compression plate 16 abuts against the limiting baffle 32, it expands the V-shaped opening of the limiting space 33 and maintains the expanded state (e.g., Figure 5 As shown), when the V-shaped opening of the limiting space 32 is in an expanded state, the included angle β of the V-shaped opening is above 150° and below 170°. The limiting baffle 32 circulating to the top of the transmission chain 132 (within the transmission channel 17) is in a transmission state, while the limiting baffle 32 circulating to the bottom of the transmission chain 132 is in a non-transmission state. In order to reduce the equipment space occupied by the limiting baffle 32 in the non-transmission state, a compression plate 16 is added below the transmission chain 132. The compression plate 16 squeezes the limiting baffle 32, causing the V-shaped opening of the limiting space 33 to expand and remain in an expanded state, thereby reducing the height space occupied by the limiting space 33 and making the feeding position at the rear end of the automatic lifting conveyor ( Figure 3 (a) The design is lower and easier to interface with other equipment / devices. In this embodiment, the V-shaped opening angle β of the limiting space 33 in the expanded state is preferably 155°.

[0031] A guide platform 161 is horizontally arranged at the front end of the compression plate 16. A guide roller 321 is rotatably arranged at the other end of the limiting baffle 32, which is hinged to the limiting groove 31. As the guide roller 321 rolls along the guide platform 161, the V-shaped opening of the limiting space 33 gradually expands until the guide roller 321 rolls to the compression plate 16 and remains in an expanded state, continuing to roll along the compression plate 16 (e.g., ...). Figure 5 As shown (the arrow without markings represents the conversion process), the guide roller 321 at the end of the limiting baffle 32 cooperates with the guide platform 161 at the front end of the compression plate 16 to guide the V-shaped opening of the limiting space 33 to gradually expand in a rolling manner until it expands to match the expansion degree of the compression plate 16, so that the transition of the limiting baffle 32 from the transmission state to the non-transmission state is smoother. At the same time, it reduces the friction generated when the limiting baffle 32 moves continuously along the compression plate 16, so that the circulation of the transmission chain 132 is smoother. In addition, when hazardous waste accumulates above the limiting baffle 32, the guide roller 321 also has a certain limiting function.

[0032] The front end of the guide platform 161 is equipped with a guide ramp 162 that gradually decreases in height from back to front. The addition of the guide ramp 162 changes the falling trajectory of the vertically falling hazardous waste material, causing it to gradually shift forward and gradually approach the center of the feed inlet of the crusher, so that it falls stably into the feed inlet, further reducing the possibility of side leakage.

[0033] A delay platform 163 is horizontally provided at the rear end of the compression plate 16. The rear end and lower end of the delay platform 163 are aligned with the rear end and lower end of the bracket 1. The addition of the delay platform 163 effectively delays the reset of the limit baffle 32 from the non-transmission state to the transmission state, making the transition of the limit baffle 32 from the lowest point of the transmission chain 132 smoother.

[0034] like Figure 6 As shown, to clearly illustrate the structure of the limiting chain plate 3, a cross-sectional view is taken at the position where the limiting chain plate 3 connects to the limiting baffle 32. The limiting baffle 32 has hinge shafts 322 on its left and right sides that are hinged to the limiting chain plate 3. The limiting chain plate 3 has hinge holes 35 that are rotatably engaged with the hinge shafts 322. A spring cavity 351 is arranged around the outer periphery of the hinge hole 35. A return torsion spring 34 is fixed in the spring cavity 351 and sleeved on the hinge shaft 322. One end of the return torsion spring 34 has a return support foot 341 extending to the back of the limiting baffle 32. In addition, the limiting chain plate 3 has fixed shafts 36 on its left and right sides that are fixed to the transmission chain 132.
