Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, and in particular to a high-safety lifting machine for bleaching powder production. Background Technology

[0002] Bleaching powder is a mixture of calcium hydroxide, calcium chloride, and calcium hypochlorite, with calcium hypochlorite as its main component and an available chlorine content of 30%-38%. It is a white or off-white powder or granules with a strong chlorine odor, is highly unstable, hygroscopic, and easily decomposes upon exposure to light, heat, water, and ethanol. Bleaching powder dissolves in water, and its aqueous solution turns litmus paper blue, which then gradually fades to white. It releases hypochlorous acid upon contact with carbon dioxide in the air and produces a large amount of chlorine gas upon contact with dilute hydrochloric acid. During the production process, bleaching powder requires a hoist for transport.

[0003] The containers held by existing elevators used in bleaching powder production are mostly open, which makes it easy for dust and bleaching powder to fall during the lifting process. If this falls onto the workers below, it will directly affect their safety and pollute their working environment. Therefore, there is an urgent need for a safer elevator for bleaching powder production to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a high-safety elevator for bleaching powder production, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-safety elevator for bleaching powder production, comprising a fixed frame for installing the elevator for bleaching powder production and a storage box for lifting bleaching powder. Two drive toothed rollers are symmetrically and rotatably installed on the inner wall of the fixed frame. Chains are meshed and connected to the outer walls of the two drive toothed rollers. Connecting rods are fixedly installed on opposite sides of the two chains, and the storage box is rotatably installed between the two connecting rods.

[0006] The top surface of the storage box is symmetrically and slidably fitted with a cover plate. The opposite side walls of the two cover plates are symmetrically and fixedly fitted with L-shaped rods. The outer wall of the storage box is symmetrically and fixedly fitted with two electric telescopic rods, and the telescopic ends of the electric telescopic rods are fixedly connected to the side walls of the L-shaped rods.

[0007] The side wall of the storage box is connected to a discharge pipe, and the top surface of the discharge pipe has a strip hole, and a partition is slidably installed in the strip hole. The outer wall of the storage box is fixedly installed with a hydraulic cylinder, and the telescopic end of the hydraulic cylinder is fixedly connected to the partition.

[0008] The storage box has a vibrating plate that is slidably installed inside, and the inclined lower end of the vibrating plate is connected to the discharge pipe.

[0009] Preferably, a limiting cylinder is fixedly installed at the lower end of the storage box, and a telescopic rod is slidably installed inside the limiting cylinder, with the top surface of the telescopic rod fixedly connected to the bottom of the vibration plate.

[0010] Preferably, a push spring is fixedly installed on the inner wall of the limiting cylinder, and the upper end of the push spring is fixedly connected to the telescopic rod.

[0011] Preferably, sliding strips are symmetrically fixedly installed on the side wall of the cover plate, and strip grooves are symmetrically opened on the upper part of the interior of the storage box.

[0012] Preferably, the two sliding strips fixedly installed on the side wall of the cover plate slide to the interior of the strip groove opened in the inner wall of the storage box.

[0013] Preferably, a sealing strip is fixedly bonded to the outer wall of the vibrating plate, and the outer wall of the sealing strip slides against the inner wall of the storage box.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This high-safety hoist for bleaching powder production benefits from the design of multiple electric telescopic rods, L-shaped rods, and cover plates. When bleaching powder needs to be loaded, the multiple electric telescopic rods are activated to push the L-shaped rods and cover plates fixed at their telescopic ends to separate, thereby opening the top of the storage box. Then, the bleaching powder can be loaded into the storage box. After the bleaching powder is filled, the electric telescopic rods are activated in reverse to bring the L-shaped rods and cover plates closer together and into contact, thereby sealing the storage box. This effectively prevents the bleaching powder in the storage box from scattering during hoisting and affecting the working environment.

[0016] This high-safety elevator for bleaching powder production benefits from the design of the discharge pipe, baffle, hydraulic cylinder, and vibrating plate. By starting the hydraulic cylinder, the baffle is raised and the discharge is opened, allowing the bleaching powder in the storage box to be discharged. Then, the vibrating plate is activated to vibrate the bleaching powder on its top surface, which guides the bleaching powder to be discharged from the discharge pipe, thereby preventing the bleaching powder from clumping in the storage box and facilitating the discharge of the bleaching powder.

[0017] This high-safety elevator for bleaching powder production benefits from the design of structures such as a limiting cylinder, telescopic rod, and push spring. The top surface of the telescopic rod is connected to the bottom of the vibrating plate, while the bottom of the telescopic rod is connected to the push spring. Therefore, it can effectively increase the vibration amplitude of the vibrating plate and prevent the vibration of the vibrating plate from being transmitted to the storage box.

[0018] This high-safety elevator for bleaching powder production effectively improves safety during the lifting process compared to existing technologies, while also preventing pollution of the working environment. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] like Figures 1 to 6 The main structure of a high-safety elevator for bleaching powder production is a fixed frame 1 for installing the elevator and a storage box 5 for bleaching powder. Two drive toothed rollers 2 are symmetrically and rotatably installed on the inner wall of the fixed frame 1. Chains 3 are meshed and connected to the outer walls of the two drive toothed rollers 2. Connecting rods 4 are fixedly installed on opposite sides of the two chains 3. The storage box 5 is rotatably installed between the two connecting rods 4. The two connecting rods 4 are arranged horizontally and parallel. Since the storage box 5 is rotatably installed between the two connecting rods 4, when the two chains 3 rise synchronously and drive the connecting rods 4 and the storage box 5 to move upward, the storage box 5 can always be kept in a parallel position, which facilitates the discharge of bleaching powder in the storage box 5.

[0032] The top surface of the storage box 5 is symmetrically and slidably fitted with a cover plate 6. L-shaped rods 8 are symmetrically and fixedly installed on the opposite side walls of the two cover plates 6. Two electric telescopic rods 7 are symmetrically and fixedly installed on the outer wall of the storage box 5. The telescopic ends of the electric telescopic rods 7 are fixedly connected to the side walls of the L-shaped rods 8. Thanks to the structure of multiple electric telescopic rods 7, L-shaped rods 8 and cover plates 6, when it is necessary to load bleaching powder, the multiple electric telescopic rods 7 are activated to push the L-shaped rods 8 and cover plates 6 fixedly installed at their telescopic ends to separate from each other, so that the top surface of the storage box 5 can be opened. Then, bleaching powder can be loaded into the storage box 5. After the bleaching powder is filled, the electric telescopic rods 7 are activated in the opposite direction to drive the L-shaped rods 8 and cover plates 6 to come closer and contact each other, so that the storage box 5 can be sealed. This can effectively prevent the bleaching powder in the storage box 5 from scattering and affecting the working environment when it is lifted.

[0033] A discharge pipe 9 is connected to the side wall of the storage box 5, and a strip-shaped hole is opened on the top surface of the discharge pipe 9. A partition 10 is slidably installed in the strip-shaped hole. A hydraulic cylinder 11 is fixedly installed on the outer wall of the storage box 5, and the telescopic end of the hydraulic cylinder 11 is fixedly connected to the partition 10. A vibrating plate 12 is slidably installed inside the storage box 5, and the inclined lower end of the vibrating plate 12 is connected to the discharge pipe 9. Thanks to the structure of the discharge pipe 9, partition 10, hydraulic cylinder 11 and vibrating plate 12, the hydraulic cylinder 11 is activated to drive the partition 10 to rise and open the discharge pipe 9. Then the bleaching powder in the storage box 5 is discharged. Then the vibrating plate 12 is activated to vibrate the bleaching powder on its top surface, which can guide the bleaching powder to be discharged from the discharge pipe 9, thereby preventing the bleaching powder from clumping in the storage box 5 and facilitating the discharge of the bleaching powder.

[0034] A limiting cylinder 13 is fixedly installed at the lower end of the storage box 5, and a telescopic rod 14 is slidably installed inside the limiting cylinder 13. The top surface of the telescopic rod 14 is fixedly connected to the bottom of the vibrating plate 12. A push spring 15 is fixedly installed on the inner wall of the limiting cylinder 13, and the upper end of the push spring 15 is fixedly connected to the telescopic rod 14. Thanks to the setting of the limiting cylinder 13, the telescopic rod 14 and the push spring 15, the vibration amplitude of the vibrating plate 12 is amplified by the push spring 15 and the telescopic rod 14, while further preventing the vibration of the vibrating plate 12 from being transmitted to the body of the storage box 5.

[0035] Sliding strips 16 are symmetrically fixedly installed on the side wall of the cover plate 6. A strip groove is symmetrically opened on the upper part of the inside of the storage box 5. The two sliding strips 16 fixedly installed on the side wall of the cover plate 6 slide and extend into the inside of the strip groove opened on the inner wall of the storage box 5. The two sliding strips 16 can effectively limit the sliding direction of the cover plate 6 and further improve the stability of the cover plate 6 when sliding.

[0036] A sealing strip 17 is fixedly bonded to the outer wall of the vibrating plate 12, and the outer wall of the sealing strip 17 slides against the inner wall of the storage box 5. Thanks to the setting of the sealing strip 17, the sealing strip 17 can further improve the sealing effect between the outer wall of the vibrating plate 12 and the inner wall of the storage box 5.

[0037] Working principle

[0038] This high-safety elevator for bleaching powder production operates by first simultaneously activating two electric telescopic rods 7. These rods, along with two L-shaped rods 8 and cover plates 6 fixed at their telescopic ends, separate, effectively opening the storage box 5. Bleaching powder can then be loaded into the storage box 5. The electric telescopic rods 7 are then activated in reverse, bringing the two cover plates 6 closer together and resealing the storage box 5. Next, the drive roller 2 is activated, moving the chain 3 and storage box 5 upwards. Upon reaching the predetermined position, two hydraulic cylinders 11 are activated, moving the partition plates 10 fixed at their telescopic ends upwards and opening the discharge pipe 9. The bleaching powder in the storage box 5 is then discharged through the discharge pipe 9. Simultaneously, the vibrating plate 12 is activated, further guiding the bleaching powder into the discharge pipe 9, thus improving the discharge efficiency.
