Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and in particular relates to a dust collector for calcium carbonate processing. Background Art

[0002] Calcium carbonate is produced by calcining limestone and other raw materials to produce lime and carbon dioxide, adding water to digest the lime to produce lime milk, then introducing carbon dioxide to carbonize the lime milk to produce calcium carbonate precipitate, and finally dehydrating, drying and crushing. Before calcining the limestone, the limestone is crushed by a crusher and then transported to a calcining furnace. The crushed limestone is dropped by the crusher onto a conveyor and transported to the calcining furnace for calcination. When the crushed limestone drops on the conveyor, a large amount of dust will be generated, and the dust will be collected by a dust collector at this time.

[0003] A calcium carbonate dust collector is disclosed in Chinese patent application No. 202320665544.4. The patent installs a transition sleeve below the crusher to collect dust into a dust collection bag. The telescopic corrugated sleeve below the transition sleeve can effectively fill the gap between the transition sleeve and the conveyor to prevent dust from overflowing from the gap and increase the dust collection effect. However, there is no device for lifting the telescopic corrugated sleeve in the above transition sleeve. The bottom of the telescopic corrugated sleeve is always in contact with the conveyor, and the equivalent is relatively large. When the crushed limestone passes through the transition sleeve and the inside of the telescopic corrugated sleeve and falls on the conveyor, the limestone on the conveyor below the telescopic corrugated sleeve will be piled up to a certain height. At this time, the conveyor is prone to scrape the limestone piled up to a certain height at the bottom of the telescopic corrugated sleeve during the limestone transportation process, causing the limestone scraped by the telescopic corrugated sleeve to overflow to the outside and fall to the outside of the conveyor, resulting in a reduction in the amount of limestone transported by the conveyor, affecting the use effect of the dust collector. For this reason, we propose a dust collector for calcium carbonate processing. Utility Model Content

[0004] The utility model aims to provide a dust collector for processing calcium carbonate, so as to solve the problem in the above-mentioned background technology that when a relatively large amount of crushed limestone passes through a transition sleeve and the inside of a telescopic corrugated sleeve and falls on a conveyor, the limestone on the conveyor below the telescopic corrugated sleeve will be piled up to a certain height. At this time, the conveyor is prone to scrape the limestone piled up to a certain height at the bottom of the telescopic corrugated sleeve during the process of transporting the limestone, so that the limestone scraped by the telescopic corrugated sleeve overflows to the outside and falls to the outside of the conveyor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust collector for calcium carbonate processing, comprising a transition sleeve, a telescopic corrugated sleeve installed at the bottom of the transition sleeve, an exhaust fan is arranged on one side of the transition sleeve, a straight pipe is fixedly arranged on the exhaust fan, two groups of branch pipes are fixedly arranged on the straight pipe, two groups of lifting mechanisms for lifting the telescopic corrugated sleeve are arranged on the transition sleeve, the lifting mechanism comprises a lower ring, the lower ring is fixed to the bottom of the telescopic corrugated sleeve, an inclined rod is fixedly arranged on the outer wall of the lower ring, a winch is fixedly arranged on the outside of the transition sleeve, a rope is wound around the outside of the winch, the bottom of the rope extends to the end of the inclined rod, a connecting plate is fixedly arranged on the bottom of the winch, and a limiting member for limiting the rope is arranged at the bottom of the connecting plate.

A connecting plate 204 is fixedly provided at the bottom of the winch 203, and a limiting member for limiting the rope 200 is provided at the bottom of the connecting plate 204.

[0023] Example 2

[0024] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting member includes a mounting plate 205, and a conical ring 206 is fixedly provided at the end of the mounting plate 205. When in use, the conical ring 206 can limit the moving rope 200, and the bottom of the rope 200 passes through the inside of the conical ring 206;

[0025] The mounting plate 205 is fixed to the bottom of the connecting plate 204. The inner wall of the conical ring 206 is provided with a plurality of rolling holes. The balls 207 roll in the rolling holes. The balls 207 are arranged inside the rolling holes.

[0026] The utility model is designed with a lifting mechanism. When the crusher crushes a large amount of limestone, a large amount of limestone passes through the transition sleeve 101 and the telescopic corrugated sleeve 105 and falls onto the conveyor. At this time, the limestone will be accumulated at a certain height on the conveyor for transportation. At this time, the rope 200 is wound up by the winch 203 to lift the bottom of the telescopic corrugated sleeve 105, which can make the bottom of the telescopic corrugated sleeve 105 contact the limestone on the conveyor and increase the dust collection effect, and will not cause the bottom of the telescopic corrugated sleeve 105 to scrape the limestone accumulated to a certain height and cause it to fall, thereby improving the use effect of the dust collector.

[0027] Example 3

[0028] Based on Example 2, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The hoist 203 is provided with a cleaning piece for cleaning the rope 200, and the cleaning piece includes a cross bar 300 and a sliding ring 301. The sliding ring 301 is slidably connected to the outside of the cross bar 300. When in use, the sliding ring 301 can move or slide with the annular cleaning brush 302. The annular cleaning brush 302 moves with the left and right movement of the rope 200. The annular cleaning brush 302 is fixed on the sliding ring 301.

[0029] The bottom of the rope 200 passes through the inside of the annular cleaning brush 302, and the cross bar 300 is fixed on the winch 203.

[0030] The cleaning piece designed in the utility model can clean the impurities attached to the rope 200 located below the winch 203 during use, thereby reducing the impurities moving to the winch 203 as the rope 200 rises, and reducing the impurities from causing wear to the rope 200 wound around the winch 203, thereby facilitating use.

[0031] In this embodiment, preferably, a flange 100 is fixedly provided on the top of the transition sleeve 101 , and an annular filter screen is provided inside the transition sleeve 101 .

[0032] The working principle and use process of this utility model:

[0033] When the utility model is in use, when the amount of limestone crushed by the crusher is relatively large, the winch 203 is started, and the rope 200 wound on the winch 203 begins to wind, and the bottom of the rope 200 drives the inclined rod 202 to move upward, drives the lower ring 201 to move, and the lower ring 201 drives the bottom of the telescopic corrugated sleeve 105 to move upward, and finally rises to the bottom of the lower ring 201 and contacts with the limestone accumulated to a certain height on the conveyor. At this time, the winch 203 stops running, which can not only increase the effect of collecting dust, but also will not cause The bottom of the telescopic corrugated sleeve 105 scrapes the limestone accumulated to a certain height to reduce the probability of falling. During the lifting process, the rope 200 will be limited by the conical ring 206 when it moves, so that the rope 200 moves stably. The ball 207 makes the rope 200 contact the ball 207 on the inner wall of the conical ring 206, reducing the probability of wear on the rope 200 caused by the direct contact between the moving rope 200 and the inner wall of the conical ring 206. When it is necessary to lower the bottom of the telescopic corrugated sleeve 105, the above-mentioned reverse principle is followed;

[0034] When some impurities are attached to the rope 200 during movement, the rope 200 is swept away with the impurities attached to the outside of the rope 200 after being wound by the winch 203, thereby reducing the impurities moving to the winch 203 as the rope 200 rises, and reducing the impurities causing wear on the rope 200 wound on the winch 203.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
