Abstract
Description
Technical Field
[0001] This utility model relates to the field of lime kiln lumps cleaning technology, specifically a height-adjustable lime kiln lumps cleaning device. Background Technology
[0002] Nodulation is a common phenomenon in lime production. The nodules formed by lime nodulation usually accumulate in the lower part of the kiln. When nodulation is severe, it can seriously affect the production process and the kiln. Due to the large size of the nodules, the lower part of the kiln can be blocked. The traditional method of cleaning nodules in the lower part of the kiln is mostly to use tools to enter the kiln and break up the lime nodules. However, due to the high temperature of the nodules, this method can easily cause personnel injury. In addition, the height of the nodules is uneven, and manual removal cannot quickly clean up the unevenly distributed nodules.
[0003] For example, announcement number CN217838753U describes a height-adjustable lime kiln lumps cleaning device. This device provides a height-adjustable lime kiln lumps cleaning device capable of quickly cleaning lumps with uneven height distribution in the lower part of the kiln body. The height-adjustable lime kiln lumps cleaning device includes an inlet pipe, a kiln body, an ash outlet hopper, a base, and a scraping mechanism. The kiln body is connected to the upper side of the base, the ash outlet hopper is connected to the lower side of the kiln body, the inlet pipe is connected to the upper side of the kiln body, and a chopping mechanism is provided on the kiln body for chopping the lumps in the lower part of the kiln body. This invention allows for the adjustment of the height of the first sliding plate by rotating the threaded rod, thereby enabling the crushing of lime lumps of different heights. This prevents lime lumps from clogging the ash hopper, improves lime processing efficiency, and eliminates the need for manual cleaning, thus enhancing safety. However, existing devices, due to their complex internal structure, generate lumps during lime preparation. Furthermore, the existing devices are fixed to the inner wall of the tank, making maintenance or cleaning extremely time-consuming after prolonged operation. Therefore, there is an urgent need to design a height-adjustable lime kiln lump cleaning device to solve these problems. Utility Model Content

[0022] Please see Figures 1-5 One embodiment provided by this utility model:
[0023] A height-adjustable lime kiln lumps cleaning device is disclosed in this application. The hydraulic cylinder 3, upper servo motor 413, and lower servo motor 514 used in this application are commercially available products. Their principles and connection methods are existing technologies well known to those skilled in the art. The device includes a tank body 1 and an outer cover 2. A hydraulic cylinder 3 is installed at the top of the outer cover 2. An adjustment mechanism 4 is installed at the bottom of the hydraulic cylinder 3. The adjustment mechanism 4 includes a drive frame 41 and a rotating disk 42. The hydraulic cylinder 3 drives the drive frame 41 to descend, and the drive frame 41 engages with and drives the rotating disk 42 to rotate. A cleaning mechanism 5 is installed at the bottom of the adjustment mechanism 4. The cleaning mechanism 5 includes a receiving component 51 and a cleaning arm 52. The receiving component 51 receives the cleaning arm 52 installed in the center. The rotating disk 42 drives the cleaning arm 52 at the bottom to work and clean.
[0024] As a further feature of this invention, the hydraulic cylinder 3 is installed in the center of the mounting plate 31, and counterweights 32 are inserted on both sides of the mounting plate 31. The two sets of counterweights 32 are installed on the upper side of the outer cover 2 to facilitate the stability of the hydraulic cylinder operation.
[0025] Furthermore, an upper fixed rotating shaft 411 is horizontally mounted inside the drive frame 41. The front end of the upper fixed rotating shaft 411 is driven by an upper servo motor 413. A horizontal bevel gear 412 is fixedly mounted on the rear side of the center of the upper fixed rotating shaft 411. The rotating disk 42 includes a fixed bearing 421, a rotating column 422, and a fixed circular plate 423. The top end of the fixed bearing 421 is fixedly mounted on the bottom side of the drive frame 41. The rotating column 422 is mounted at the center of the fixed bearing 421. A vertical bevel gear 424 is fixedly mounted on the top end of the rotating column 422. The vertical bevel gear 424 meshes with the horizontal bevel gear 412. A fixed circular plate 423 is fixedly mounted on the bottom end of the rotating column 422. A cleaning mechanism 5 is fixedly mounted on the bottom end of the fixed circular plate 423, which can rotate the cleaning arm to clean the inner wall of the tank and improve efficiency.
[0026] As a further improvement of this utility model, the storage component 51 includes two sets of side plates 511 and a lower fixed rotating shaft 512. The two sets of side plates 511 are fixed to the bottom side of the fixed circular plate 423. The lower fixed rotating shaft 512 is inserted into the center of the two sets of side plates 511. The lower fixed rotating shaft 512 is driven by a lower servo motor 514. A limit gear 513 is installed at the center of the lower fixed rotating shaft 512. A cleaning arm 52 is fixed at the right end of the limit gear 513. The cleaning arm 52 includes an extension arm 521 and an extension arm 524. A convex groove 522 is opened inside the extension arm 521. A fixing plate 523 is installed on the upper right side of the convex groove 522. An extension arm 524 is provided inside the extension arm 521. The left end of the extension arm 524 is installed on the inner wall of the extension arm 521 by a linear spring 525. Two sets of arc plates 526 are fixed on the right end of the extension arm 524. The center of the two sets of arc plates 526 is connected and fixed by multiple sets of scrapers 527 extending to the outside. A material discharge port 528 is opened in the center of the bottom arc plate 526. The angle of the cleaning arm can be adjusted by the storage component. This design not only facilitates adjustment but also makes it easy to store, improving the applicability of the device.
[0027] Working principle: When in use, the user first installs the hydraulic cylinder 3, the adjusting mechanism 4, and the cleaning mechanism 5 inside the tank body 1, and then uses the counterweight 32 to fix the hydraulic cylinder 3 on both sides of the mounting plate 31.
[0028] When cleaning of tank 1 is required, the lower servo motor 514 is first powered on to drive the lower fixed rotating shaft 512 to rotate. The rotation of the lower fixed rotating shaft 512 drives the centrally fixed limiting gear 513 to rotate. The rotation of the limiting gear 513 drives the fixed extension arm 521 to rotate and adjust it to be perpendicular to tank 1. When the two sets of arc plates 526 inside the extension arm 521 contact the inner wall of tank 1 with the central scraper 527, the extension wall 524 fixed to the arc plates 526 can be adjusted in position within the convex groove 522 under the action of the linear spring 525.
[0029] Then, by powering on the servo motor 413, the upper fixed rotating shaft 411 is driven to rotate within the drive frame 41. The rotation of the upper fixed rotating shaft 411 drives the rear-mounted horizontal bevel gear 412 to mesh with the vertical bevel gear 424, which in turn drives the rotating column 422. The rotation of the rotating column 422 then drives the fixed circular plate 423 and the cleaning arm 52 to rotate, cleaning the inner wall of the tank 1. Finally, only the height of the hydraulic cylinder 3 needs to be adjusted to clean the inner wall of the tank 1. This is the complete working principle of this utility model.
