Description

Technical Field

[0001] This utility model belongs to the technical field of elevator equipment, specifically relating to an elevator for calcium hydroxide processing. Background Technology

[0002] Calcium hydroxide, commonly known as slaked lime or quicklime, is a white powdery inorganic strong alkali obtained by slaking quicklime (calcium oxide) with water. It is widely used in construction, environmental protection, metallurgy, chemical industry, food, and water treatment. In calcium hydroxide processing, elevators are responsible for vertically lifting bulk or bagged quicklime raw materials and finished calcium hydroxide powder from the ground or low-level storage silos to the feed inlets of high-level digesters, classifiers, finished product silos, and other equipment. This achieves continuous, closed, and automatic material conveying, prevents dust from escaping, and improves the flexibility of the production line's height layout and overall operating efficiency.

[0003] Chain (plate chain / ring chain) bucket elevators are commonly used in calcium hydroxide processing. The mainstream types are the NE plate chain series and the self-closing bucket series. The whole machine consists of a head sprocket, a tail sprocket, a closed-loop chain, several buckets, a sealed shell, and matching inlet / outlet ports. The head is equipped with a drive device (motor + reducer + hydraulic coupling), and the tail is equipped with a spring or counterweight tensioning device. An inspection door and support components can be added to the middle section of the shell to prevent the chain from swinging.

[0004] In existing calcium hydroxide processing elevators, calcium hydroxide tends to clump and adhere inside the hopper during use, gradually reducing the effective volume of the hopper and thus decreasing the load per unit hopper. Consequently, the elevator's conveying capacity decreases, and the clumps can easily fall off and cause cross-contamination, affecting the activity and whiteness of the finished product. Timely cleaning of the hopper is necessary. Existing cleaning operations typically require stopping the machine, disconnecting the power, knocking down the hopper, and chiseling, which is time-consuming, labor-intensive, and generates dust, increasing the difficulty of occupational health and safety management for workers. Frequent knocking can also deform the hopper's steel plate, crack the welds, shorten its service life, and affect its use. Utility Model Content

[0005] The purpose of this invention is to provide a lifting machine for calcium hydroxide processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A calcium hydroxide processing elevator includes: a base plate and an elevator body. The bottom of the elevator body is fixedly mounted on the top of the base plate. The elevator body has multiple hoppers inside, and bushings are installed inside the hoppers. Two symmetrically arranged connecting plates are fixedly mounted on the inner side wall of the bushings. Connecting frames adapted to the connecting plates are fixedly mounted on the outer side walls at both ends of the hoppers. The ends of the connecting plates are inserted into the connecting frames. Support components are provided inside the connecting frames, and fixing mechanisms are provided on the connecting frames.

[0008] The fixing mechanism includes a mounting frame fixedly mounted on the outer wall of the connecting frame, a movable plate slidably mounted on the inner wall of the mounting frame, a fixing block fixedly mounted at the end of the movable plate, an opening adapted to the fixing block on the outer wall of the connecting frame, a connecting groove adapted to the fixing block on the outer wall of the connecting plate, the end of the fixing block being inserted into the connecting groove, and an adjustment component inside the mounting frame.

[0009] Preferably, the adjustment component includes a fixing plate fixedly disposed inside the mounting frame, a threaded rod being disposed through and rotatably disposed on the fixing plate, a threaded connection being disposed between the fixing block and the threaded rod, and a threaded groove adapted to the threaded rod being formed on the outer wall of the fixing block.

[0010] Preferably, a rotating rod is rotatably provided on the inner sidewall of the mounting frame, and the rotating rod and the threaded rod are fixedly connected by a coupling. A worm gear is fixedly sleeved on the outer sidewall of the rotating rod. Multiple sliders are fixedly provided on the outer sidewall of the moving plate, and multiple slide rails adapted to the sliders are fixedly provided on the inner sidewall of the mounting frame.

[0011] Preferably, a worm gear is rotatably provided on the inner sidewall of the mounting frame, the worm gear and the worm wheel are meshed together, and a handwheel is fixedly provided at the end of the worm gear through the mounting frame.

[0012] Preferably, the supporting component includes multiple fixing rods fixedly disposed on the bottom of the connecting frame, a limiting block fixedly disposed on the top of the fixing rod, and a slot adapted to the limiting block and the fixing rods being opened at the bottom of the connecting plate. The limiting block and the fixing rods are inserted into the slots, and the same support plate is slidably sleeved on the multiple fixing rods. The top of the support plate and the bottom of the connecting plate are in tight contact.

[0013] Preferably, a spring is sleeved on the outer wall of the fixing rod, and the top and bottom of the spring are in close contact with the bottom of the support plate and the bottom of the connecting frame, respectively.

[0014] Preferably, multiple positioning strips are fixedly provided on the outer walls of both ends of the bushing, and a positioning groove adapted to the positioning strips is opened on the inner wall of the hopper, and the positioning strips are inserted into the positioning grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Turning the handwheel drives the worm gear and threaded rod to rotate synchronously. The fixed block, which is threadedly connected to the threaded rod, is inserted linearly into the connecting groove of the connecting plate under the guidance of the moving plate and the slide rail, realizing the quick locking of the bushing and the hopper. Reverse rotation unlocks it. The operation is convenient. The removable bushing effectively isolates calcium hydroxide powder from the metal inner wall of the hopper. After it clumps, it can be cleaned simply by pulling out the bushing. There is no need to knock the hopper, which prevents the hopper from deforming, the weld from cracking, and dust from flying. This extends the service life of the hopper, reduces downtime maintenance time and occupational health risks, and improves the conveying efficiency and operational reliability of the entire elevator.

[0025] 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.

[0026] Example 1:

[0027] Please see Figure 1 - Figure 7 As shown, a calcium hydroxide processing elevator includes: a base plate 1 and an elevator body 2. The bottom of the elevator body 2 is fixedly installed on the top of the base plate 1. Multiple hoppers 3 are provided inside the elevator body 2. Bushings 4 are provided inside the hoppers 3. Two symmetrically arranged connecting plates 5 are fixedly installed on the inner side wall of the bushings 4. Connecting frames 6 adapted to the connecting plates 5 are fixedly installed on the outer side walls at both ends of the hoppers 3. The ends of the connecting plates 5 are inserted into the connecting frames 6. A support component is provided inside the connecting frames 6. A fixing mechanism is provided on the connecting frames 6.

[0028] The fixing mechanism includes a mounting frame 7 fixedly mounted on the outer side wall of the connecting frame 6, a movable plate 8 slidably mounted on the inner side wall of the mounting frame 7, a fixing block 9 fixedly mounted at the end of the movable plate 8, an opening adapted to the fixing block 9 on the outer side wall of the connecting frame 6, a connecting groove adapted to the fixing block 9 on the outer side wall of the connecting plate 5, the end of the fixing block 9 being inserted into the connecting groove, and an adjustment component inside the mounting frame 7.

[0029] As can be seen from the above, by adjusting the components to control the entry and exit of the fixing block 9 into the connecting groove, the connection between the connecting plate 5 and the connecting frame 6 is fixed and disconnected, thereby controlling the installation and disassembly of the bushing 4. The bushing 4 effectively isolates the calcium hydroxide powder from the metal inner wall of the hopper 3. After it clumps, it can be cleaned simply by pulling out the bushing 4, without having to knock the hopper 3. This prevents the hopper from deforming, the weld from cracking, and dust from flying, extends the service life of the hopper 3, reduces downtime maintenance time and occupational health risks, and improves the conveying efficiency and operational reliability of the entire elevator.

[0030] Specifically, regarding the aforementioned adjustment assembly, the adjustment assembly includes a fixed plate 10 fixedly installed inside the mounting frame 7, a threaded rod 11 that passes through and rotatably is provided on the fixed plate 10, a threaded connection is provided between the fixed block 9 and the threaded rod 11, and a threaded groove adapted to the threaded rod 11 is provided on the outer wall of the fixed block 9.

[0031] A rotating rod 12 is rotatably provided on the inner side wall of the mounting frame 7. The rotating rod 12 and the threaded rod 11 are fixedly connected by a coupling. A worm gear 13 is fixedly sleeved on the outer side wall of the rotating rod 12. Multiple sliders are fixedly provided on the outer side wall of the movable plate 8. Multiple slide rails that are adapted to the sliders are fixedly provided on the inner side wall of the mounting frame 7.

[0032] A worm gear 14 is rotatably mounted on the inner side wall of the mounting frame 7. The worm gear 14 and the worm wheel 13 are meshed together. The end of the worm gear 14 passes through the mounting frame 7 and is fixedly mounted with a handwheel 15.

[0033] As can be seen from the above, by rotating the handwheel 15, the worm 14 is driven to rotate, and the worm 14 drives the worm wheel 13, which meshes with it, to rotate. In turn, the threaded rod 11 is driven to rotate through the rotating rod 12 and the coupling. Since the fixed block 9 meshes with the threaded rod 11 through its threaded groove, and its movement is restricted to horizontal sliding by the moving plate 8, the slider and the slide rail, the rotational motion of the threaded rod 11 is converted into the precise linear forward and backward motion of the fixed block 9. The reverse self-locking characteristics of the worm wheel 13 and the worm 14 transmission ensure that the fixed block 9 will not loosen or fall off on its own due to material impact or equipment vibration in a vibrating working environment, thus ensuring the reliability and safety of the connection.

[0034] Specifically, regarding the aforementioned support assembly, the support assembly includes multiple fixed rods 16 fixedly mounted on the bottom of the connecting frame 6. A limit block is fixedly mounted on the top of the fixed rod 16. The bottom of the connecting plate 5 has a slot adapted to the limit block and the fixed rod 16. The limit block and the fixed rod 16 are inserted into the slot. The same support plate 17 is slidably sleeved on the multiple fixed rods 16. The top of the support plate 17 and the bottom of the connecting plate 5 are in tight contact.

[0035] A spring 18 is fitted on the outer wall of the fixing rod 16. The top and bottom of the spring 18 are in close contact with the bottom of the support plate 17 and the bottom of the connecting frame 6, respectively.

[0036] As can be seen from the above, in its natural state, the elastic force of spring 18 pushes the support plate 17 upward. When the bushing 4 is installed, the connecting plate 5 is inserted downward into the connecting frame 6, and its bottom will press against the support plate 17 and move downward against the elastic force of spring 18. The rebound force generated after the spring 18 is compressed will continuously push the connecting plate 5 upward through the support plate 17. When the fixing block 9 is retracted and unlocked, the compressed spring 18 will immediately release its elastic force and push the support plate 17 and the connecting plate 5 upward, so that the bushing 4 will automatically spring up a small distance, thereby easily breaking any possible slight adhesion and providing the operator with the starting force to pull out the bushing 4, making disassembly more effortless and convenient.

[0037] Example 2:

[0038] Multiple positioning strips 19 are fixedly installed on the outer walls of both ends of the bushing 4. The inner wall of the hopper 3 is provided with positioning grooves that are compatible with the positioning strips 19, and the positioning strips 19 are inserted into the positioning grooves.

[0039] As can be seen from the above, when installing bushing 4, the operator must first align the positioning strips 19 at both ends of bushing 4 with the corresponding positioning grooves on the inner wall of hopper 3 before the bushing 4 can be pushed into place smoothly. During the alignment process, the connecting plate 5 on it can be accurately aligned with the connecting frame 6 on the outer side of hopper 3, which facilitates the installation of bushing 4. It should be noted that when the positioning strip 19 is fully inserted into the positioning groove, the connecting groove and the fixing block 9 are aligned, which facilitates the insertion of the fixing block 9 into the connecting groove.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
