Description

Technical Field

[0001] This utility model belongs to the field of hazardous waste storage technology, specifically a semi-solid hazardous waste storage device. Background Technology

[0002] my country is a major producer of hazardous waste, and the amount of hazardous waste generated domestically is increasing year by year. Hazardous waste is divided into solid hazardous waste, liquid hazardous waste and semi-solid hazardous waste. Among them, semi-solid hazardous waste accounts for about 60% of the total amount of hazardous materials, and its composition is complex and difficult to dispose of.

[0003] Existing semi-solid hazardous waste is mostly stored in drums, and for easy transfer, the bottom of the containers is usually equipped with a pallet. However, the pallet structure of existing semi-solid hazardous waste storage drums is simple, requiring forklifts or other mechanical equipment for transfer, which is inconvenient for movement in small temporary storage rooms. Practical experience shows that when solids are stacked, there is friction and compression between them, resulting in large spaces between the stored semi-solid hazardous waste. Practical experience also shows that shaking the storage container during solid storage can make the stored solids more compact and reduce space occupation. Combined with this, the storage capacity of the drum can be increased and the space occupied by semi-solid hazardous waste can be reduced. However, existing semi-solid hazardous waste storage drums are not easy to shake and it is difficult to generate vibration, resulting in a significant reduction in the storage capacity of the drum. Therefore, it is necessary to develop a semi-solid hazardous waste storage device to overcome the shortcomings of existing technologies. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a semi-solid hazardous waste storage device with the advantage of high storage efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a semi-solid hazardous waste storage device, including a storage tank, a chassis provided below the storage tank, a guardrail installed on the top of the chassis, the storage tank being enclosed inside the guardrail, a support component provided at the bottom of the chassis, a handrail provided at the top of the chassis, and a filling port provided at the top of the storage tank.

[0006] The support assembly includes a support frame disposed around the bottom of the chassis.

A rotating shaft passes through the middle of the traveling wheel. Both ends of the rotating shaft pass through the traveling wheel and are connected to the support frame. A brake pad is also disposed inside the support frame. The lower end of the brake pad swings along the inside of the support frame and eventually fits tightly against the outer surface of the traveling wheel. A support column is also installed at the bottom of the chassis.

[0007] Preferably, the support column is composed of sleeve rods and abutment rods that are nested together. The sleeve rods are threaded onto the lower end of the abutment rods, the upper end of the abutment rods is fixedly connected to the bottom of the chassis, and the lower end of the sleeve rods abuts against the ground.

[0009] Preferably, the inner diameter of the sliding cavity is larger than the inner diameter of the through hole, and the outer diameter of the sliding shaft is larger than the outer diameter of the connecting shaft; the difference between the inner diameter of the sliding cavity and the outer diameter of the sliding shaft is greater than the difference between the inner diameter of the through hole and the outer diameter of the connecting shaft.

[0010] Preferably, the interior of the sliding cavity is provided with a plurality of evenly distributed buffer springs, one end of which is abutted against and connected to the outer surface of the sliding shaft.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, this utility model provides a semi-solid hazardous waste storage device, including a storage tank 1, a chassis 3 is provided below the storage tank 1, a guardrail 2 is installed on the top of the chassis 3, the storage tank 1 is wrapped inside the guardrail 2, a support component 4 is provided at the bottom of the chassis 3, a handrail 5 is provided at the top of the chassis 3, and a filling port 6 is provided at the top of the storage tank 1.

[0026] The support assembly 4 includes a support frame 41 disposed around the perimeter of the chassis 3. A shock-absorbing assembly 42 disposed at the bottom of the chassis 3 is connected to the upper end of the support frame 41. A traveling wheel 43 is movably mounted on the lower end of the support frame 41. A rotating shaft 44 passes through the middle of the traveling wheel 43, with both ends of the rotating shaft 44 penetrating the traveling wheel 43 and connecting to the support frame 41. A brake pad 45 is also disposed inside the support frame 41. The lower end of the brake pad 45 swings along the interior of the support frame 41 and eventually fits tightly against the outer surface of the traveling wheel 43. A support column 46 is also installed at the bottom of the chassis 3. Due to the placement of the shock-absorbing assembly 42, and with the cooperation of the traveling wheel 43, it facilitates the movement of workers. The operator uses the chassis 3 to transfer the storage tank 1 and the semi-solid hazardous waste it contains over a short distance. With the help of the brake pads 45, the traveling wheels 43 can be locked. Then, with the action of the shock-absorbing component 42, the chassis 3 and the storage tank 1 can be promptly reset after shock, thereby achieving the effect of improving the compactness of the filling through shock. Due to the setting of the brake pads 45, with the cooperation of the support frame 41, by swinging the lower end of the brake pads 45 up and down, it can be fixed after swinging under the restriction of the support frame 41. At the same time, after swinging down, it can be pressed against the outer surface of the traveling wheels 43, thereby achieving the purpose of braking, thus facilitating the shock-absorbing component 42 to provide the shock effect.

[0027] The support column 46 is composed of a sleeve rod and a support rod that are interlocked. The sleeve rod is threaded onto the lower end of the support rod, the upper end of the support rod is fixedly connected to the bottom of the chassis 3, and the lower end of the sleeve rod rests on the ground. Due to the setting of the support column 46, with the cooperation of the chassis 3, the length of the support column 46 can be changed by rotating it, that is, the distance between its lower end and the bottom of the chassis 3 can be changed, so that the lower end of the support column 46 can rest on the ground or detach from the ground. This facilitates the movement of the chassis 3 and the storage tank 1 as a whole by controlling the movement of the chassis 3 and the storage tank 1 through the traveling wheels 43, and achieves the purpose of providing a vibration effect for the chassis 3 and the storage tank 1 as a whole through the buffer vibration component 42 after locking the traveling wheels 43.

[0028] The shock-absorbing assembly 42 includes a sliding cavity 421 located at the bottom of the chassis 3. A sliding shaft 423 is slidably installed inside the sliding cavity 421. A through hole 422 communicating with the bottom of the sliding cavity 421 is provided at the bottom of the chassis 3. A connecting shaft 424 passes through the through hole 422. The upper and lower ends of the connecting shaft 424 are fixedly connected to the sliding shaft 423 and the support frame 41, respectively.

[0029] The inner diameter of the sliding cavity 421 is larger than that of the through hole 422, and the outer diameter of the sliding shaft 423 is larger than that of the connecting shaft 424. The difference between the inner diameter of the sliding cavity 421 and the outer diameter of the sliding shaft 423 is greater than the difference between the inner diameter of the through hole 422 and the outer diameter of the connecting shaft 424. Due to the arrangement of the sliding shaft 423 and the connecting shaft 424, with the cooperation of the connecting shaft 424 and the through hole 422, it can be ensured that the sliding shaft 423 can slide in any direction within the sliding cavity 421, so that the chassis 3 can push the chassis 3 to either side to make the storage tank 1 vibrate. At the same time, it can also be ensured that the sliding shaft 423 can always remain within the sliding cavity 421 and will not fall into the through hole 422, thereby ensuring the stability of the connection between the sliding shaft 423 and the sliding cavity 421.

[0030] The sliding cavity 421 is equipped with several evenly distributed buffer springs 425, one end of which is connected to the outer surface of the sliding shaft 423. Due to the arrangement of several buffer springs 425, with the cooperation of the sliding shaft 423 and the linkage ring 426, when the chassis 3 is pushed to any side of the horizontal plane by the handrail 5, the chassis 3 and the storage tank 1 as a whole can obtain the reverse restoring force in time, thereby improving the vibration effect.

[0031] The sliding cavity 421 is internally fitted with a linkage ring 426. A gap is left between the linkage ring 426 and the sliding shaft 423. Several buffer springs 425 are disposed in the gap, and the other end of the buffer springs 425 is abutted against the inner wall of the linkage ring 426. Due to the setting of the linkage ring 426, it can not only cooperate with the sliding shaft 423 to abut the buffer springs 425, but also follow the rotation of the sliding shaft 423, the support frame 41 and the traveling wheel 43 under the drive of the sliding shaft 423 and the buffer springs 425. This ensures that when the traveling wheel 43 cooperates with the chassis 3 to turn in any direction, it can provide the other end of the buffer springs 425 with the cooperation of the sliding shaft 423 through the linkage ring 426.

[0032] The top and bottom of the slide shaft 423 are movably embedded with a number of uniformly distributed drag-reducing balls 427. The bottom and top of the slide shaft 423 are respectively supported by the drag-reducing balls 427 against the bottom and top of the inner cavity of the slide cavity 421. The drag-reducing balls 427 are always located outside the top of the through hole 422. Due to the setting of the drag-reducing balls 427, it can be ensured that the top and bottom of the slide shaft 423 can be tightly connected to the slide cavity 421, thereby ensuring the stability of the slide shaft 423 sliding in the horizontal plane, and effectively reducing the contact friction resistance between the outer surface of the slide shaft 423 and the inner wall of the slide cavity 421.

[0033] Working principle and usage process of this utility model:

[0034] Rotate the support column 46 to lift its bottom off the ground and lock the brake pad 45 corresponding to the walking wheel 43. Then open the filling port 6 to fill the semi-solid hazardous waste. During this process, push the chassis 3 back and forth with the handrail 5 and make the storage tank 1 and guardrail 2 on top of it swing back and forth. Since the walking wheel 43 is locked, the reciprocating chassis 3 can slide relative to the sliding shaft 423 and connecting shaft 424 through the sliding cavity 421 and through hole 422 with the cooperation of the drag-reducing ball 427, and compress the corresponding buffer spring 425. At the same time, it stretches the buffer spring 425 on the other side. Thus, with the cooperation of the elastic restoring force of the buffer spring 425, the purpose of filling the semi-solid hazardous waste into the storage tank 1 by reciprocating vibration is achieved, thereby ensuring that the semi-solid hazardous waste is filled tightly.

[0035] Since force can be applied in any direction through the handle 5, and the chassis 3 and the storage tank 1 on top can be shaken with the cooperation of the buffer shock assembly 42, the sliding shaft 423 and the linkage ring 426 ensure that when the chassis 3 and the storage tank 1 shake in any direction in the horizontal plane, they can obtain sufficient restoring force with the cooperation of several buffer springs 425, thereby ensuring that the chassis 3 and the storage tank 1 can be reset in time and improving the compaction effect of shock filling.
